Integrating the leader trait perspective with dominance complementarity theory, we propose team power distance as an important boundary condition for the indirect impact of leader extraversion, agreeableness, and conscientiousness on team performance through a team's potency beliefs and through relational identification with the leader. Using time-lagged, 3-source data from 71 teams, we found that leader extraversion had a positive indirect impact on team in-role and extrarole performance through relational identification, but only for high power distance teams; leader conscientiousness had a positive influence on team in-role performance through team potency, but only for high power distance teams; and leader agreeableness had a positive effect on team in-role and extrarole performance via relational identification and on team in-role performance via team potency, but only for low power distance teams. The findings address prior inconsistencies regarding the relationships between leader traits and team effectiveness, identify an important boundary condition and key team processes that bridge the links, and provide a deeper understanding of the role of leader traits in teams.

Crisis resource management principles dictate appropriate distribution of mental and/or physical workload so as not to overwhelm any one team member. Workload during pediatric emergencies is not well studied. The National Aeronautics and Space Administration-Task Load Index is a multidimensional tool designed to assess workload validated in multiple settings. Low workload is defined as less than 40, moderate 40-60, and greater than 60 signify high workloads. Our hypothesis is that workload among both team leaders and team members is moderate to high during a simulated pediatric sepsis scenario and that team leaders would have a higher workload than team members. Multicenter observational study. Nine pediatric simulation centers (five United States, three Canada, and one United Kingdom). Team leaders and team members during a 12-minute pediatric sepsis scenario. National Aeronautics and Space Administration-Task Load Index. One hundred twenty-seven teams were recruited from nine sites. One hundred twenty-seven team leaders and 253 team members completed the National Aeronautics and Space Administration-Task Load Index. Team leader had significantly higher overall workload than team member (51 ± 11 vs 44 ± 13; p < 0.01). Team leader had higher workloads in all subcategories except in performance where the values were equal and in physical demand where team members were higher than team leaders (29 ± 22 vs 18 ± 16; p < 0.01). The highest category for each group was mental 73 ± 13 for team leader and 60 ± 20 for team member. For team leader, two categories, mental (73 ± 17) and effort (66 ± 16), were high workload, most domains for team member were moderate workload levels. Team leader and team member are under moderate workloads during a pediatric sepsis scenario with team leader under high workloads (> 60) in the mental demand and effort subscales. Team leader average significantly higher workloads. Consideration of decreasing

Team Leader Structuring for Team Effectiveness and Team Learning in Command-and-Control Teams.
van der Haar, Selma; Koeslag-Kreunen, Mieke; Euwe, Eline; Segers, Mien
2017-04-01
Due to their crucial and highly consequential task, it is of utmost importance to understand the levers leading to effectiveness of multidisciplinary emergency management command-and-control (EMCC) teams. We argue that the formal EMCC team leader needs to initiate structure in the team meetings to support organizing the work as well as facilitate team learning, especially the team learning process of constructive conflict. In a sample of 17 EMCC teams performing a realistic EMCC exercise, including one or two team meetings (28 in sum), we coded the team leader's verbal structuring behaviors (1,704 events), rated constructive conflict by external experts, and rated team effectiveness by field experts. Results show that leaders of effective teams use structuring behaviors more often (except asking procedural questions) but decreasingly over time. They support constructive conflict by clarifying and by making summaries that conclude in a command or decision in a decreasing frequency over time.

The present research examines the impact of leaders' confidence in their team on the team confidence and performance of their teammates. In an experiment involving newly assembled soccer teams, we manipulated the team confidence expressed by the team leader (high vs neutral vs low) and assessed team members' responses and performance as they unfolded during a competition (i.e., in a first baseline session and a second test session). Our findings pointed to team confidence contagion such that when the leader had expressed high (rather than neutral or low) team confidence, team members perceived their team to be more efficacious and were more confident in the team's ability to win. Moreover, leaders' team confidence affected individual and team performance such that teams led by a highly confident leader performed better than those led by a less confident leader. Finally, the results supported a hypothesized mediational model in showing that the effect of leaders' confidence on team members' team confidence and performance was mediated by the leader's perceived identity leadership and members' team identification. In conclusion, the findings of this experiment suggest that leaders' team confidence can enhance members' team confidence and performance by fostering members' identification with the team. © 2015 John Wiley & Sons A/S.

Trauma team leaders' non-verbal communication: video registration during trauma team training.
Härgestam, Maria; Hultin, Magnus; Brulin, Christine; Jacobsson, Maritha
2016-03-25
There is widespread consensus on the importance of safe and secure communication in healthcare, especially in trauma care where time is a limiting factor. Although non-verbal communication has an impact on communication between individuals, there is only limited knowledge of how trauma team leaders communicate. The purpose of this study was to investigate how trauma team members are positioned in the emergency room, and how leaders communicate in terms of gaze direction, vocal nuances, and gestures during trauma team training. Eighteen trauma teams were audio and video recorded during trauma team training in the emergency department of a hospital in northern Sweden. Quantitative content analysis was used to categorize the team members' positions and the leaders' non-verbal communication: gaze direction, vocal nuances, and gestures. The quantitative data were interpreted in relation to the specific context. Time sequences of the leaders' gaze direction, speech time, and gestures were identified separately and registered as time (seconds) and proportions (%) of the total training time. The team leaders who gained control over the most important area in the emergency room, the "inner circle", positioned themselves as heads over the team, using gaze direction, gestures, vocal nuances, and verbal commands that solidified their verbal message. Changes in position required both attention and collaboration. Leaders who spoke in a hesitant voice, or were silent, expressed ambiguity in their non-verbal communication: and other team members took over the leader's tasks. In teams where the leader had control over the inner circle, the members seemed to have an awareness of each other's roles and tasks, knowing when in time and where in space these tasks needed to be executed. Deviations in the leaders' communication increased the ambiguity in the communication, which had consequences for the teamwork. Communication cannot be taken for granted; it needs to be practiced

We examined the interactive effects of leader group prototypicality, accountability, and team identification on team-oriented behavior of leaders, thus extending the social identity perspective on leadership to the study of leader behavior. An experimental study (N = 152) supported our hypothesis that leader accountability relates more strongly to team-oriented behavior for group nonprototypical leaders than for group prototypical leaders. A multisource field study with leaders (N = 64) and their followers (N = 209) indicated that this interactive effect is more pronounced for leaders who identify more strongly with their team. We discuss how these findings further develop the social identity analysis of leadership. PsycINFO Database Record (c) 2013 APA, all rights reserved.

In this study, we evaluate the role of leader charisma in fostering positive affective team climate and preventing negative affective climate. The analysis of a longitudinal database of 137 bank branches by means of hierarchical moderated regression shows that leader charisma has a stronger effect on team optimism than on team tension. In addition, the leader's influence and the frequency of leader-team interaction moderate the relationship between charisma and affective climate. However, whereas the leader's influence enhances the relationship between leader charisma and positive affective climate, the frequency of interaction has counterproductive effects.

Leader evaluation and team cohesiveness in the process of team development: A matter of gender?
Sczesny, Sabine; Gumí, Tània; Guimerà, Roger; Sales-Pardo, Marta
2017-01-01
Leadership positions are still stereotyped as masculine, especially in male-dominated fields (e.g., engineering). So how do gender stereotypes affect the evaluation of leaders and team cohesiveness in the process of team development? In our study participants worked in 45 small teams (4–5 members). Each team was headed by either a female or male leader, so that 45 leaders (33% women) supervised 258 team members (39% women). Over a period of nine months, the teams developed specific engineering projects as part of their professional undergraduate training. We examined leaders’ self-evaluation, their evaluation by team members, and team cohesiveness at two points of time (month three and month nine, the final month of the collaboration). While we did not find any gender differences in leaders’ self-evaluation at the beginning, female leaders evaluated themselves more favorably than men at the end of the projects. Moreover, female leaders were evaluated more favorably than male leaders at the beginning of the project, but the evaluation by team members did not differ at the end of the projects. Finally, we found a tendency for female leaders to build more cohesive teams than male leaders. PMID:29059231

The role of justice in team member satisfaction with the leader and attachment to the team.
Phillips, J M; Douthitt, E A; Hyland, M M
2001-04-01
This study examined the effects of team decision accuracy, team member decision influence, leader consideration behaviors, and justice perceptions on staff members' satisfaction with the leader and attachment to the team in hierarchical decision-making teams. The authors proposed that staff members' justice perceptions would mediate the relationship between (a) team decision accuracy, (b) the amount of influence a staff member has in the team leader's decision, and (c) the leader's consideration behaviors and staff attachment to the team and satisfaction with the leader. The results of an experiment involving 128 participants in a total of 64 teams, who made recommendations to a confederate acting as the team leader, generally support the proposed model.

Interprofessional Care and Role of Team Leaders.
Kaini, B K
2015-01-01
Interprofessional care is an essential part of the health service delivery system. It helps to achieve improved care and to deliver the optimal and desired health outcomes by working together, sharing and learning skills. Health care organisation is a collective sum of many leaders and followers. Successful delivery of interprofessional care relies on the contribution of interprofessional care team leaders and health care professionals from all groups. The role of the interprofessional care team leader is vital to ensuring continuity and consistency of care and to mobilise and motivate health care professionals for the effective delivery of health services. Medical professionals usually lead interprofessional care teams. Interprofessional care leaders require various skills and competencies for the successful delivery of interprofessional care.

The authors examined how leader briefings and team-interaction training influence team members' knowledge structures concerning processes related to effective performance in both routine and novel environments. Two-hundred thirty-seven undergraduates from a large mid-Atlantic university formed 79 three-member tank platoon teams and participated in a low-fidelity tank simulation. Team-interaction training, leader briefings, and novelty of performance environment were manipulated. Findings indicated that both leader briefings and team-interaction training affected the development of mental models, which in turn positively influenced team communication processes and team performance. Mental models and communication processes predicted performance more strongly in novel than in routine environments. Implications for the role of team-interaction training, leader briefings, and mental models as mechanisms for team adaptation are discussed.

The authors present the findings of the first phase of a 3-year study developing a skills training curriculum for mental health team leaders. A factor model empirically generated from clinical team members was compared to Bass' (1990) Multifactor Model of Leadership. Members of mental health teams generated individual responses to questions about effective leaders. Results from this survey were subsequently administered to a sample of mental health team members. Analysis of these data yielded six factors: Autocratic Leadership, Clear Roles and Goals, Reluctant Leadership, Vision, Diversity Issues, and Supervision. Additional analyses suggest Bass' Multifactor Model offers a useful paradigm for developing a curriculum specific to the needs of mental health team leaders.

Flexible knowledge repertoires: communication by leaders in trauma teams
2012-01-01
Background In emergency situations, it is important for the trauma team to efficiently communicate their observations and assessments. One common communication strategy is “closed-loop communication”, which can be described as a transmission model in which feedback is of great importance. The role of the leader is to create a shared goal in order to achieve consensus in the work for the safety of the patient. The purpose of this study was to analyze how formal leaders communicate knowledge, create consensus, and position themselves in relation to others in the team. Methods Sixteen trauma teams were audio- and video-recorded during high fidelity training in an emergency department. Each team consisted of six members: one surgeon or emergency physician (the designated team leader), one anaesthesiologist, one nurse anaesthetist, one enrolled nurse from the theatre ward, one registered nurse and one enrolled nurse from the emergency department (ED). The communication was transcribed and analyzed, inspired by discourse psychology and Strauss’ concept of “negotiated order”. The data were organized and coded in NVivo 9. Results The findings suggest that leaders use coercive, educational, discussing and negotiating strategies to work things through. The leaders in this study used different repertoires to convey their knowledge to the team, in order to create a common goal of the priorities of the work. Changes in repertoires were dependent on the urgency of the situation and the interaction between team members. When using these repertoires, the leaders positioned themselves in different ways, either on an authoritarian or a more egalitarian level. Conclusion This study indicates that communication in trauma teams is complex and consists of more than just transferring messages quickly. It also concerns what the leaders express, and even more importantly, how they speak to and involve other team members. PMID:22747848

In this study, we identify leader humility, characterized by being open to admitting one's limitations, shortcomings, and mistakes, and showing appreciation and giving credit to followers, as a critical leader characteristic relevant for team creativity. Integrating the literatures on creativity and leadership, we explore the relationship between leader humility and team creativity, treating team psychological safety and team information sharing as mediators. Further, we hypothesize and examine team power distance as a moderator of the relationship. We tested our hypotheses using data gathered from 72 work teams and 354 individual members from 11 information and technology firms in China using a multiple-source, time-lagged research design. We found that the positive relationship between leader humility and team information sharing was significant and positive only within teams with a low power distance value. In addition, leader humility was negatively related to team psychological safety in teams with a high power distance value, whereas the relationship was positive yet nonsignificant in teams with low power distance. Furthermore, team information sharing and psychological safety were both significantly related to team creativity. We discuss theoretical and practical implications for leadership and work teams.

Rapid response teams (RRTs) improve the detection of and response to deteriorating patients. Professional hierarchies and the multidisciplinary nature of RRTs hinder team performance. This study assessed whether an intervention involving crew resource management training of team leaders could improve team performance. In situ observations of RRT activations were performed pre- and post-training intervention. Team performance and dynamics were measured by observed adherence to an ideal task list and by the Team Emergency Assessment Measure tool, respectively. Multiple quartile (median) and logistic regression models were developed to evaluate change in performance scores or completion of specific tasks. Team leader and team introductions (40% to 90%, P = .004; 7% to 45%, P = .03), floor team presentations in Situation Background Assessment Recommendation format (20% to 65%, P = .01), and confirmation of the plan (7% to 70%, P = .002) improved after training in patients transferred to the ICU (n = 35). The Team Emergency Assessment Measure metric was improved in all 4 categories: leadership (2.5 to 3.5, P < .001), teamwork (2.7 to 3.7, P < .001), task management (2.9 to 3.8, P < .001), and global scores (6.0 to 9.0, P < .001) for teams caring for patients who required transfer to the ICU. Targeted crew resource management training of the team leader resulted in improved team performance and dynamics for patients requiring transfer to the ICU. The intervention demonstrated that training the team leader improved behavior in RRT members who were not trained. Copyright © 2017 by the American Academy of Pediatrics.

Although coaches and players recognise the importance of leaders within the team, research on athlete leadership is sparse. The present study expands knowledge of athlete leadership by extending the current leadership classification and exploring the importance of the team captain as formal leader of the team. An online survey was completed by 4,451 participants (31% females and 69% males) within nine different team sports in Flanders (Belgium). Players (N = 3,193) and coaches (N = 1,258) participated on all different levels in their sports. Results revealed that the proposed additional role of motivational leader was perceived as clearly distinct from the already established roles (task, social and external leader). Furthermore, almost half of the participants (44%) did not perceive their captain as the principal leader on any of the four roles. These findings underline the fact that the leadership qualities attributed to the captain as the team's formal leader are overrated. It can be concluded that leadership is spread throughout the team; informal leaders rather than the captain take the lead, both on and off the field.

A multidisciplinary approach to team nursing within a low secure service: the team leader role.
Nagi, Claire; Davies, Jason; Williams, Marie; Roberts, Catherine; Lewis, Roger
2012-01-01
This article critically examines the clinical utility of redesigning a nursing practice model within the Intensive Support and Intervention Service, a new low secure mental health facility in the United Kingdom. Specifically, the "team nursing" approach to care delivery has been adapted to consist of multidisciplinary team leaders as opposed to nursing team leaders. The authors describe the role, properties, and functions of the multidisciplinary team leader approach. The authors provide examples of the benefits and challenges posed to date and the ways in which potential barriers have been overcome. Nursing care leadership can be provided by multidisciplinary staff. An adapted model of team nursing can be implemented in a low secure setting. © 2011 Wiley Periodicals, Inc.

The present study was designed to produce novel theoretical insight regarding how leader humility and team member characteristics foster the conditions that promote shared leadership and when shared leadership relates to team effectiveness. Drawing on social information processing theory and adaptive leadership theory, we propose that leader humility facilitates shared leadership by promoting leadership-claiming and leadership-granting interactions among team members. We also apply dominance complementary theory to propose that team proactive personality strengthens the impact of leader humility on shared leadership. Finally, we predict that shared leadership will be most strongly related to team performance when team members have high levels of task-related competence. Using a sample composed of 62 Taiwanese professional work teams, we find support for our proposed hypothesized model. The theoretical and practical implications of these results for team leadership, humility, team composition, and shared leadership are discussed.

We examine the effect of (in)congruence between leaders' and teams' power distance values on team effectiveness. We hypothesize that the (in)congruence between these values would differentially predict team effectiveness, with procedural justice climate serving as a mediator. Using multisource data and polynomial regression, we found that similarities (and differences) between leaders' and their teams' power distance values can have consequential effects on teams' justice climate and, ultimately, their effectiveness (viz., team performance and team organizational citizenship behavior). We conclude that to fully understand the implications of power distance, one should consider the multiple perspectives of both leaders and team members. (c) 2013 APA, all rights reserved.

Do followers perform better when their leader expresses anger or when their leader expresses happiness? We propose that this depends on the follower's level of agreeableness. Anger is associated with hostility and conflict-states that are at odds with agreeable individuals' goals. Happiness facilitates affiliation and positive relations-states that are in line with agreeable individuals' goals. Accordingly, the two studies we conducted showed that agreeableness moderates the effects of a leader's emotional displays. In a scenario study, participants with lower levels of agreeableness responded more favorably to an angry leader, whereas participants with higher levels of agreeableness responded more favorably to a neutral leader. In an experiment involving four-person teams, teams composed of participants with lower average levels of agreeableness performed better when their leader expressed anger, whereas teams composed of participants with higher average levels of agreeableness performed better when their leader expressed happiness. Team performance was mediated by experienced workload, which was highest among agreeable followers with an angry leader. Besides having important practical implications, the findings shed new light on the fundamental question of how emotional expressions regulate social behavior.

Despite the increasing prevalence of ethnic diversity, findings regarding its effects on team performance remain contradictory. We suggest that past inconsistencies can be reconciled by examining the joint impact of leader behavior and leader categorization tendencies in ethnically diverse teams. We propose that leaders who exhibit high levels of visionary leader behavior and also have the tendency to categorize their team members into in- and out-groups will facilitate a negative effect of ethnic diversity on team communication and financial performance, whereas leaders who exhibit visionary behaviors but do not tend to categorize will lead ethnically diverse teams to positive outcomes. We find support for these ideas in a study of 100 retail outlets.

Norwegian trauma team leaders - training and experience: A national point prevalence study
2011-01-01
Background The treatment of trauma victims is a complex multi-professional task in a stressful environment. We previously found that trauma team members perceive leadership as the most important human factor. The aim of the present study was to assess the experience and education of Norwegian trauma team leaders, and allow them to describe their perceived educational needs. Methods We conducted an anonymous descriptive study using a point prevalence methodology based on written questionnaires. All 45 hospitals in Norway receiving severely injured trauma victims were contacted on a randomly selected weeknight during November 2009. Team leaders were asked to specify what trauma related training programs they had participated in, how much experience they had, and what further training they wished, if any. Results Response rate was 82%. Slightly more than half of the team leaders were residents. The median working experience as a surgeon among team leaders was 7.5 years. Sixty-eight percent had participated in multi-professional training in non-technical skills, while 54% had passed the advanced trauma life support(ATLS) course. Fifty-one percent were trained in damage control surgery. A median of one course per team leader was needed to comply with the new proposed national standards. Team leaders considered training in damage control surgery the most needed educational objective. Conclusions Level of experience among team leaders was highly variable and their educational background insufficient according to international and proposed national standards. Proposed national standards should be urgently implemented to ensure equal access to high quality trauma care. PMID:21975088

We develop a model in which cognitive and affective trust in the leader mediate the relationship between leader behavior and team psychological states that, in turn, drive team performance. The model is tested on a sample of 191 financial services teams in Hong Kong and the U.S. Servant leadership influenced team performance through affect-based trust and team psychological safety. Transformational leadership influenced team performance indirectly through cognition-based trust. Cognition-based trust directly influenced team potency and indirectly (through affect-based trust) influenced team psychological safety. The effects of leader behavior on team performance were fully mediated through the trust in leader variables and the team psychological states. Servant leadership explained an additional 10% of the variance in team performance beyond the effect of transformational leadership. We discuss implications of these results for research on the relationship between leader behavior and team performance, and for efforts to enhance leader development by combining knowledge from different leadership theories.

Effective team leadership in cardiopulmonary resuscitation (CPR) is well recognized as a crucial factor influencing performance. Generally, leadership training focuses on task requirements for leading as well as non-leading team members. We provided crisis resource management (CRM) training only for designated team leaders of advanced life support (ALS) trained teams. This study assessed the impact of the CRM team leader training on CPR performance and team leader verbalization. Forty-five teams of four members each were randomly assigned to one of two study groups: CRM team leader training (CRM-TL) and additional ALS-training (ALS add-on). After an initial lecture and three ALS skill training tutorials (basic life support, airway management and rhythm recognition/defibrillation) of 90-min each, one member of each team was randomly assigned to act as the team leader in the upcoming CPR simulation. Team leaders of the CRM-TL groups attended a 90-min CRM-TL training. All other participants received an additional 90-min ALS skill training. A simulated CPR scenario was videotaped and analyzed regarding no-flow time (NFT) percentage, adherence to the European Resuscitation Council 2010 ALS algorithm (ADH), and type and rate of team leader verbalizations (TLV). CRM-TL teams showed shorter, albeit statistically insignificant, NFT rates compared to ALS-Add teams (mean difference 1.34 (95% CI -2.5, 5.2), p = 0.48). ADH scores in the CRM-TL group were significantly higher (difference -6.4 (95% CI -10.3, -2.4), p = 0.002). Significantly higher TLV proportions were found for the CRM-TL group: direct orders (difference -1.82 (95% CI -2.4, -1.2), p < 0.001); undirected orders (difference -1.82 (95% CI -2.8, -0.9), p < 0.001); planning (difference -0.27 (95% CI -0.5, -0.05) p = 0.018) and task assignments (difference -0.09 (95% CI -0.2, -0.01), p = 0.023). Training only the designated team leaders in CRM improves performance of the entire team, in

When leaders interact in teams with their subordinates, they build social capital that can have positive effects on team performance. Does this social capital affect team performance because subordinates come to see the leader as charismatic? We answered this question by examining 2 models. First, we tested the charisma-to-centrality model…

High quality team leadership is important for the outcome of medical emergencies. However, the behavioral marker of leadership are not well defined. The present study investigated frequency of behavioral markers of shared mental models (SMM) on quality of medical management. Training video recordings of 27 trauma teams simulating emergencies were analyzed according to team -leader's frequency of shared mental model behavioral markers. The results showed a positive correlation of quality of medical management with leaders sharing information without an explicit demand for the information ("push" of information) and with leaders communicating their situational awareness (SA) and demonstrating implicit supporting behavior. When separating the sample into higher versus lower performing teams, the higher performing teams had leaders who displayed a greater frequency of "push" of information and communication of SA and supportive behavior. No difference was found for the behavioral marker of team initiative, measured as bringing up suggestions to other teammembers. The results of this study emphasize the team leader's role in initiating and updating a team's shared mental model. Team leaders should also set expectations for acceptable interaction patterns (e.g., promoting information exchange) and create a team climate that encourages behaviors, such as mutual performance monitoring, backup behavior, and adaptability to enhance SMM.

The predictors and correlates of positive functioning among community prevention teams have been examined in a number of research studies; however, the role of personality has been neglected. In this study, we examined whether team member and leader personality dimensions assessed at the time of team formation predicted local prevention team functioning 2.5-3.5 years later. Participants were 159 prevention team members in 14 communities participating in the PROSPER study of prevention program dissemination. Three aspects of personality, aggregated at the team level, were examined as predictors: Openness to Experience, Conscientiousness, and Agreeableness. A series of multivariate regression analyses were performed that accounted for the interdependency of five categories of team functioning. Results showed that average team member Openness was negatively, and Conscientiousness was positively linked to team functioning. The findings have implications for decisions about the level and nature of technical assistance support provided to community prevention teams.

Does leader-affective presence influence communication of creative ideas within work teams?
Madrid, Hector P; Totterdell, Peter; Niven, Karen
2016-09-01
Affective presence is a novel, emotion-related personality trait, supported in experimental studies, concerning the extent to which a person makes his or her interaction partners feel the same way (Eisenkraft & Elfenbein, 2010). Applying this concept to an applied teamwork context, we proposed that team-leader-affective presence would influence team members' communication of creative ideas. Multilevel modeling analysis of data from a survey study conducted with teams from a consultancy firm confirmed that team-leader-affective presence interacted with team-member creative idea generation to predict inhibition of voicing their ideas. Specifically, withholding of ideas was less likely when team members generated creative ideas and their team leader had higher positive affective presence or lower negative affective presence. These findings contribute to emotion research by showing affective presence as a trait with interpersonal meaning, which can shape how cognition is translated into social behavior in applied performance contexts, such as teamwork in organizations.

Learning and adapting to change are imperative as teams today face unprecedented change. Yet, an important part of learning involves challenging assumptions and addressing differences of opinion openly within a group--the kind of behaviors that pose the potential for embarrassment or threat. How can leaders foster an environment in which team members feel it is safe to take interpersonal risks in order to learn? In a study of 71 teams, we found that psychological safety and learning behavior were higher for teams with mastery than performance goal instructions or no goal instructions. Team psychological safety mediated the relationship between mastery and performance goal instructions and learning behavior. Findings contribute to our understanding of how leader-assigned goals are related to psychological safety and learning behavior in a team context, and suggest approaches to foster such processes.

Do you see what we see? The complex effects of perceptual distance between leaders and teams.
Gibson, Cristina B; Cooper, Cecily D; Conger, Jay A
2009-01-01
Previous distance-related theories and concepts (e.g., social distance) have failed to address the sometimes wide disparity in perceptions between leaders and the teams they lead. Drawing from the extensive literature on teams, leadership, and cognitive models of social information processing, the authors develop the concept of leader-team perceptual distance, defined as differences between a leader and a team in perceptions of the same social stimulus. The authors investigate the effects of perceptual distance on team performance, operationalizing the construct with 3 distinct foci: goal accomplishment, constructive conflict, and decision-making autonomy. Analyzing leader, member, and customer survey responses for a large sample of teams, the authors demonstrate that perceptual distance between a leader and a team regarding goal accomplishment and constructive conflict have a nonlinear relationship with team performance. Greater perceptual differences are associated with decreases in team performance. Moreover, this effect is strongest when a team's perceptions are more positive than the leader's are (as opposed to the reverse). This pattern illustrates the pervasive effects that perceptions can have on team performance, highlighting the importance of developing awareness of perceptions in order to increase effectiveness. Implications for theory and practice are delineated. (PsycINFO Database Record (c) 2009 APA, all rights reserved).

To investigate health care improvement team coaching activities from the perspectives of coachees, coaches and unit leaders in two national improvement collaboratives. Despite numerous methods to improve health care, inconsistencies in success have been attributed to factors that include unengaged staff, absence of supportive improvement resources and organisational inertia. Mixed methods sequential exploratory study design, including quantitative and qualitative data from interprofessional improvement teams who received team coaching. The coachees (n = 382), coaches (n = 9) and leaders (n = 30) completed three different data collection tools identifying coaching actions perceived to support improvement activities. Coachees, coaches and unit leaders in both collaboratives reported generally positive perceptions about team coaching. Four categories of coaching actions were perceived to support improvement work: context, relationships, helping and technical support. All participants agreed that regardless of who the coach is, emphasis should include the four categories of team coaching actions. Leaders should reflect on their efforts to support improvement teams and consider the four categories of team coaching actions. A structured team coaching model that offers needed encouragement to keep the team energized, seems to support health care improvement. © 2013 John Wiley & Sons Ltd.

Human values in the team leader selection process.
Rovira, Núria; Ozgen, Sibel; Medir, Magda; Tous, Jordi; Alabart, Joan Ramon
2012-03-01
The selection process of team leaders is fundamental if the effectiveness of teams is to be guaranteed. Human values have proven to be an important factor in the behaviour of individuals and leaders. The aim of this study is twofold. The first is to validate Schwartz's survey of human values. The second is to determine whether there are any relationships between the values held by individuals and their preferred roles in a team. Human values were measured by the items of the Schwartz Value Survey (SVS) and the preferred roles in a team were identified by the Belbin Self Perception Inventory (BSPI). The two questionnaires were answered by two samples of undergraduate students (183 and 177 students, respectively). As far as the first objective is concerned, Smallest Space Analysis (SSA) was performed at the outset to examine how well the two-dimensional circular structure, as postulated by Schwartz, was represented in the study population. Then, the results of this analysis were compared and contrasted with those of two other published studies; one by Schwartz (2006) and one by Ros and Grad (1991). As for the second objective, Pearson correlation coefficients were computed to assess the associations between the ratings on the SVS survey items and the ratings on the eight team roles as measured by the BSPI.

High-performance teams and the physician leader: an overview.
Majmudar, Aalap; Jain, Anshu K; Chaudry, Joseph; Schwartz, Richard W
2010-01-01
The complexity of health care delivery within the United States continues to escalate in an exponential fashion driven by an explosion of medical technology, an ever-expanding research enterprise, and a growing emphasis on evidence-based practices. The delivery of care occurs on a continuum that spans across multiple disciplines, now requiring complex coordination of care through the use of novel clinical teams. The use of teams permeates the health care industry and has done so for many years, but confusion about the structure and role of teams in many organizations contributes to limited effectiveness and suboptimal outcomes. Teams are an essential component of graduate medical education training programs. The health care industry's relative lack of focus regarding the fundamentals of teamwork theory has contributed to ineffective team leadership at the physician level. As a follow-up to our earlier manuscripts on teamwork, this article clarifies a model of teamwork and discusses its application to high-performance teams in health care organizations. Emphasized in this discussion is the role played by the physician leader in ensuring team effectiveness. By educating health care professionals on the fundamentals of high-performance teamwork, we hope to stimulate the development of future physician leaders who use proven teamwork principles to achieve the goals of trainee education and excellent patient care.

Taking the reins: the effects of new leader status and leadership style on team performance.
Sauer, Stephen J
2011-05-01
New leaders face a challenging task when they take charge of their teams. They have to determine how best to guide the work process, and they must understand how their behaviors will affect the members of their team. This research examines how a newly assigned team leader's status moderates subordinates' reactions to different leadership styles to affect assessments of the leader's self-confidence and effectiveness, and how this impacts team performance. Across 2 experimental studies, results demonstrate that low-status leaders are rated as more effective when they use a directive style, whereas high-status leaders are viewed as more effective when they use a participative style, and this relationship is mediated by perceptions of self-confidence. In addition, teams whose leaders are viewed more favorably perform better on a complex group task. These findings imply that low-status individuals are able to enhance their level of personal power by drawing on whatever positional power they hold, whereas high-status individuals are better off relying solely on their personal power to influence others. This research also provides a clear demonstration that assessments of new leaders' behaviors are subject to an appraisal that is clouded by observers' status perceptions and attributions.

This study examines the underlying mechanism of the crossover process in work teams. Drawing on conservation of resources theory, we hypothesize that a leader's psychological distress positively influences subordinates' psychological distress through abusive supervision. We further hypothesize that team performance attenuates the association between a leader's psychological distress and abusive supervision. In addition, we expect that psychological capital attenuates the positive relationship between abusive supervision and subordinates' psychological distress. Participants were drawn from 86 business teams, and multisource data were collected. The hypotheses were tested with multilevel analysis. Results supported the crossover of psychological distress from leader to subordinates, and abusive supervision serves as a mediating mechanism. The positive relationship between a leader's distress and abusive supervision is stronger when team performance is lower. In addition, the positive relationship between abusive supervision and subordinates' psychological distress is stronger when subordinates' psychological capital is lower.

Background Nosocomial infections caused by Pseudomonas aeruginosa presenting resistance to beta-lactam drugs are one of the most challenging targets for antimicrobial therapy, leading to substantial increase in mortality rates in hospitals worldwide. In this context, P. aeruginosa harboring acquired mechanisms of resistance, such as production of metallo-beta-lactamase (MBLs) and extended-spectrum beta-lactamases (ESBLs) have the highest clinical impact. Hence, this study was designed to investigate the presence of genes codifying for MBLs and ESBLs among carbapenem resistant P. aeruginosa isolated in a Brazilian 720-bed teaching tertiary care hospital. Methods Fifty-six carbapenem-resistant P. aeruginosa strains were evaluated for the presence of MBL and ESBL genes. Strains presenting MBL and/or ESBL genes were submitted to pulsed-field gel electrophoresis for genetic similarity evaluation. Results Despite the carbapenem resistance, genes for MBLs (blaSPM-1 or blaIMP-1) were detected in only 26.7% of isolates. Genes encoding ESBLs were detected in 23.2% of isolates. The blaCTX-M-2 was the most prevalent ESBL gene (19.6%), followed by blaGES-1 and blaGES-5 detected in one isolate each. In all isolates presenting MBL phenotype by double-disc synergy test (DDST), the blaSPM-1 or blaIMP-1 genes were detected. In addition, blaIMP-1 was also detected in three isolates which did not display any MBL phenotype. These isolates also presented the blaCTX-M-2 gene. The co-existence of blaCTX-M-2 with blaIMP-1 is presently reported for the first time, as like as co-existence of blaGES-1 with blaIMP-1. Conclusions In this study MBLs production was not the major mechanism of resistance to carbapenems, suggesting the occurrence of multidrug efflux pumps, reduction in porin channels and production of other beta-lactamases. The detection of blaCTX-M-2,blaGES-1 and blaGES-5 reflects the recent emergence of ESBLs among antimicrobial resistant P. aeruginosa and the extraordinary

The present study examined the impact of athlete leaders' perceived confidence on their teammates' confidence and performance. Male basketball players (N = 102) participated in groups of 4. To manipulate leaders' team confidence, the appointed athlete leader of each newly formed basketball team (a confederate) expressed either high or low team confidence. The results revealed an effect of team confidence contagion such that team members had greater team confidence when the leader expressed high (rather than low) confidence in the team's success. Second, the present study sought to explain the mechanisms through which this contagion occurs. In line with the social identity approach to leadership, structural equation modeling demonstrated that this effect was partially mediated by team members' increased team identification. Third, findings indicated that when leaders expressed high team confidence, team members' performance increased during the test, but when leaders expressed low confidence, team members' performance decreased. Athlete leaders thus have the capacity to shape team members' confidence--and hence their performance--in both positive and negative ways. In particular, by showing that they believe in "our team," leaders are able not only to make "us" a psychological reality, but also to transform "us" into an effective operational unit.

Interdisciplinary preceptor teams to improve the clinical nurse leader student experience.
Moore, Penny; Schmidt, Debra; Howington, Lynnette
2014-01-01
The Clinical Nurse Leader (CNL) role was introduced by the American Association of Colleges of Nursing (AACN) in 2003 (AACN, 2003). There are now over 2,500 certified CNLs in the United States. Still some areas of the country have no CNLs in practice; this was true of north central Texas until May 2010 when Texas Christian University (TCU) had its first graduating class. Lack of CNLs to serve as preceptors for the practicum courses in the CNL program was one concern, although AACN does offer options when CNLs are not available. TCU's CNL teaching team developed the interdisciplinary preceptor team (IPT) model to strengthen the practicum component of CNL education at TCU. One advantage of the IPT model is the match it provides with several CNL competencies: lateral integration of care via interdisciplinary teams, member and leader of health care teams, skillful communication within teams, and implementation of an interdisciplinary approach to safe, quality, patient care. Components of the IPT model are discussed with specific information about preceptor selection, team development, and examples of feedback from preceptors and students. © 2014.

In this study, we have developed real-time PCR assays using SYBR Green chemistry to detect all known alleles of bla KPC , bla NDM , and bla OXA-48 -like carbapenemase genes in water, sediment, and biofilm samples collected from hospital and wastewater treatment plant (WWTP) effluents and rivers receiving chronic WWTP discharges. The amplification of bla KPC , bla NDM , and bla OXA-48 DNA was linear over 7 log dilutions (R 2 between 0.995 and 0.997) and showing efficiencies ranging from 92.6% to 100.3%. The analytical sensitivity indicated that the reaction for bla KPC , bla NDM , and bla OXA-48 -like genes was able to detect 35, 16, and 19 copy numbers per assay, respectively. The three carbapenemase genes were detected in hospital effluents, whereas only the bla KPC and bla NDM genes were detected in biofilm and sediment samples collected from wastewater-impacted rivers. The detection of bla KPC , bla NDM , and bla OXA-48 -like genes in different matrices suggests that carbapenem-resistant bacteria occur in both planktonic and benthic habitats thus expanding the range of resistance reservoirs for last-resort antibiotics. We believe that these real-time PCR assays would be a powerful tool for the rapid detection and quantification of bla KPC , bla NDM , and bla OXA-48 -like genes in complex environmental samples.

Nosocomial infections caused by Acinetobacter spp. resistant to carbapenems are increasingly reported worldwide. Carbapenem-resistant Acinetobacter (CRA) is becoming a serious concern with increasing patient morbidity, mortality, and lengths of hospital stay. Therefore, the rapid detection of CRA is essential for epidemiological surveillance. Polymerase chain reaction (PCR) has been extensively used for the rapid identification of most pathogens. In this study, we have developed two multiplex real-time PCR assays to detect and differentiate A. baumannii and non-A. baumannii Acinetobacter spp, and common carbapenemase genes, including blaNDM, blaOXA-23-like, blaOXA-40-like, blaOXA-51-like, and blaOXA-58-like. We demonstrate the potential utility of these assays for the direct detection of blaNDM-, blaOXA-23-like-, blaOXA-40-like-, blaOXA-51-like-, and blaOXA-58-like-positive CRA in clinical specimens. Primers were specifically designed, and two multiplex real-time PCR assays were developed: multiplex real-time PCR assay1 for the detection of Acinetobacter baumannii 16S–23S rRNA internal transcribed spacer sequence, the Acinetobacter recA gene, and class-B-metalloenzyme-encoding gene blaNDM; and multiplex real-time PCR assay2 to detect class-D-oxacillinase-encoding genes (blaOXA-23-like, blaOXA-40-like, blaOXA-51-like,and blaOXA-58-like). The assays were performed on an ABI Prism 7500 FAST Real-Time PCR System. CRA isolates were used to compare the assays with conventional PCR and sequencing. Known amounts of CRA cells were added to sputum and fecal specimens and used to test the multiplex real-time PCR assays. The results for target and nontarget amplification showed that the multiplex real-time PCR assays were specific, the limit of detection for each target was 10 copies per 20 μL reaction volume, the assays were linear over six log dilutions of the target genes (r2 > 0.99), and the Ct values of the coefficients of variation for intra- and interassay

Fatal errors due to miscommunication among members of trauma teams are 2 to 4 times more likely to occur than in other medical teams, yet most trauma team members do not receive communication effectiveness training. A needs assessment was conducted to examine trauma team members' miscommunication experiences and research scientists' evaluations of live trauma activations. The purpose of this study is to demonstrate that communication training is necessary and highlight specific team communication competencies that trauma teams should learn to improve communication during activations. Data were collected in 2 phases. Phase 1 required participants to complete a series of surveys. Phase 2 included live observations and assessments of pediatric trauma activations using the assessment of pediatric resuscitation team assessments (APRC-TA) and assessment of pediatric resuscitation leader assessments (APRC-LA). Data were collected at a southwestern pediatric hospital. Trauma team members and leaders completed surveys at a meeting and were observed while conducting activations in the trauma bay. Trained research scientists and clinical staff used the APRC-TA and APRC-LA to measure trauma teams' medical performance and communication effectiveness. The sample included 29 healthcare providers who regularly participate in trauma activations. Additionally, 12 live trauma activations were assessed monday to friday from 8am to 5pm. Team members indicated that communication training should focus on offering assistance, delegating duties, accepting feedback, and controlling emotional expressions. Communication scores were not significantly different from medical performance scores. None of the teams were coded as effective medical performance and ineffective team communication and only 1 team was labeled as ineffective leader communication and effective medical performance. Communication training may be necessary for trauma teams and offer a deeper understanding of the communication

To describe the experiences of 14 clinical nursing leaders introducing a knowledge translation (KT) project into one metropolitan acute care hospital in South Australia. The study also explored team members' and service managers' experiences. KT strategies assume that local (nursing) clinical leaders have the capacity and capability to champion innovation combining positional leadership roles (ward leader) with a project lead role. There is limited evidence to support these assumptions. Semi-structured interviews of clinical nursing leaders and managers were undertaken at month 4 and 12 of the project. Data were also collected from the interdisciplinary team members (n = 28). Clinical nursing leaders identified risks and anxieties associated with taking on an additional leadership role, whereas managers acknowledged the multiple pressures on the system and the need for local level innovation. Team members generally reported positive experiences. With support, clinical nursing leaders can effectively embrace KT project leadership roles that complement their positional leadership roles. Clinical nursing leaders' experiences differed from nursing and medical managers' experiences. Managers need to be more attuned to the personal risks local leaders experience, providing support for leaders to experiment and innovate. Managers need to integrate local priorities with broader system wide agendas. © 2011 The Authors. Journal compilation © 2011 Blackwell Publishing Ltd.

The relationship between a leader's personality and his team's performance has been established in organisational research, but the underlying process and mechanism responsible for this effect have not been fully explored. Both the traditional multiple linear regression and the multilevel structural equation model approaches were used in this study to test a proposed mediating model of subordinates' perception of collective efficacy between leader personality and team performance. The results show that the team leader's extraversion and conscientiousness personality traits were related positively to both the team-average (individual) perception of collective efficacy and team performance, and the collective efficacy mediated the relationship of the leader's personality traits and team performance. This study also discusses how Chinese cultural elements play a role in such a mediating model. © 2014 International Union of Psychological Science.

A growing body of evidence shows that team training can develop essential team skills and contribute to better patient outcomes. Current simulation-based team training (SBTT) programmes most often include targets and feedback focused on the whole team and/or leader, ignoring the follower as a unique entity. By considering followers' individual experiences, and tailoring behavioural targets for training and feedback, SBTT could be improved. Our aim was to explore the individual experiences and behaviours of leaders and followers during the early phase of SBTT, and we hypothesised that leaders and followers would show different responses. Medical students (n=54) participated in half-day SBTT including three video-recorded scenarios. Self-efficacy was assessed pretraining and post-training. For each scenario (n=36), the individual teamwork behaviours, concentration, mental strain and the team's clinical performance were recorded. Data were analysed using a mixed model allowing for participants to be their own control in their roles as leader or follower. Self-efficacy improved. In the role of leader, participants communicated to a greater extent and experienced higher mental strain and concentration than they did in the role of follower. The increased self-efficacy enables a positive learning outcome after only three scenarios. Individual experiences and behaviours differed between the role of leader and that of follower. By shedding further light on leaders' and followers' individual experiences and behaviours, targets for training and feedback could be specified in order to improve SBTT.

Effective assessment and resuscitation of trauma patients requires an organised, multidisciplinary team. Literature evaluating leadership roles of nurses in trauma resuscitation and their effect on team performance is scarce. To assess the effect of allocating the most senior nurse as team leader of trauma patient assessment and resuscitation on communication, documentation and perceptions of leadership within an Australian emergency department. The study design was a pre-post-test survey of emergency nursing staff (working at resuscitation room level) perceptions of leadership, communication, and documentation before and after the implementation of a nurse leader role. Patient records were audited focussing on initial resuscitation assessment, treatment, and nursing clinical entry. Descriptive statistical analyses were performed. Communication trended towards improvement. All (100%) respondents post-test stated they had a good to excellent understanding of their role, compared to 93.2% pre-study. A decrease (58.1-12.5%) in 'intimidating personality' as a negative aspect of communication. Nursing leadership had a 6.7% increase in the proportion of those who reported nursing leadership to be good to excellent. Accuracy of clinical documentation improved (P = 0.025). Trauma nurse team leaders improve some aspects of communication and leadership. Development of trauma nurse leaders should be encouraged within trauma team training programmes.

It has been said that the construction industry must unleash its potential as a source of wealth creation and provide opportunity for the betterment of quality of life. In ensuring the quality of workmanship at construction sites, supervisory skills of site supervisors need to be enhanced. It stressed out that to match business growth and excellence overseas, we must recognize and act on the importance of continuously developing niche expertise and capabilities. Undoubtedly, the role of research in determining the specific leadership skills and the needed core capabilities cannot be over-emphasized. In ensuring the quality of workmanship at construction sites, leadership skills especially supervisory skill for site supervisors need to be enhanced. In this study, quantitative research design with survey questionnaire was used to collect the data and simple random sampling was employed in selecting 248 respondents involving team leaders in construction industry from whole of Malaysia. The data was analyzed using descriptive and inferential statistics; ANOVA in SPSS 21.0. Training and experience in leadership has been found to be significance to leadership capability of team leaders. The opinions from the respondents also indicated that they need the training of leadership and they had to enhance themselves to enable them to become better and more competitive leaders. The results of this assessment can pinpoint the areas needing improvement and therefore can be used as basis in designing and/or deciding development programmes. This study also found that generally the team leaders in construction industry needed more opportunities to expand their leadership capability to become the effective leaders in future.

Although treatment teams have been examined often in the mental health literature, this literature seldom addresses the crucial property of "teamness"--the key set of intangible phenomena that allow a team to function synergistically as more than the sum of its parts, and with a sense of team identity. In this paper, the concept of the work group is used to develop a framework for understanding the factors contributing to effective team functioning and identity, an their implications for the tasks of team leadership and sociotherapy: "the art of maintaining a social system in which the treatment of an individual patient can best occur" (Edelson 1970). Leadership activities that promote team cohesiveness and boundary maintenance are discussed, and suggestions are provided for ways in which the subjective experiences and emotional reactions of the leader and team members can be used to promote improved task performance and clinical care.

This study examines team performance as a moderator of the relationship between decision influence and outcomes relevant to team effectiveness in hierarchical teams with distributed ex pertise. In this type of team staff members have unique roles and make recommendations to the team leader, who ultimately makes the team's final decisions. It is suggested that the positive rela tionship between decision influence and favorable outcomes (e.g., satisfaction) consistently described in the literature is dependent on team performance in this type of team. Specifically, team effec tiveness outcomes are proposed to be consistently more favorable in higher performing than in lower performing teams. Decision influence is proposed to relate positively to member satisfaction with the leader, willingness to return, and self-efficacy and to relate negatively to withdrawal in higher performing teams. The opposite pattern of relationships is expected in lower performing teams. A laboratory study was conducted with 228 undergradu ates performing a computer task as subordinates in 76 four-person teams with a confederate leader. The results generally support the hypotheses and illustrate a dilemma for leaders attempting to manage team effectiveness. Copyright 2000 Academic Press.

Evaluating Peer-Led Team Learning: A Study of Long-Term Effects on Former Workshop Peer Leaders
NASA Astrophysics Data System (ADS)
Gafney, Leo; Varma-Nelson, Pratibha
2007-03-01
Peer-led team learning (PLTL) is a program of small-group workshops, attached to a course, under the direction of trained peer leaders who have completed the course. Peer leaders ensure that team members engage with the materials and with each other, they help build commitment and confidence, and they encourage discussion. Studies of PLTL have found that grades and retention improve, and students value the workshops as important in their learning. With a ten-year history, it was possible to study the impact of PLTL on former leaders as they took subsequent steps into graduate work and careers. A survey was developed, piloted, revised, and placed online. Nearly 600 former leaders from nine institutions were contacted; 119 completed surveys were received. Respondents reported that leading the workshops reinforced the breadth and depth of their own learning, helped them develop personal qualities such as confidence and perseverance, and fostered a variety of presentation and team-related skills. The respondents offered rich insights into issues in implementing workshops. This study contributes to the literature on involvement theory in the academic development of college students.

Occurrence of Enterobacter hormaechei carrying blaNDM-1 and blaKPC-2 in China.
Yang, Biwei; Feng, Yu; McNally, Alan; Zong, Zhiyong
2018-02-01
Three carbapenem-resistant clinical isolates of the Enterobacter cloacae complex (ECC) were recovered from different patients in a hospital. All 3 isolates carried 2 carbapenemase genes bla KPC-2 and bla NDM-1 . A study was performed to characterize their relatedness and to investigate possible links among the patients. Whole genome sequencing revealed that the isolates were Enterobacter hormaechei and belonged to ST177 of the ECC. There were 19-142 single nucleotide polymorphisms (SNPs) between the isolates, suggesting that the isolates were likely from a central reservoir, which might have existed for some time. bla KPC-2 and bla NDM-1 were carried on 2 different IncF-type plasmids in the isolates. The 3 bla NDM-1 -carrying plasmids were almost identical and were self-transmissible, while the bla KPC-2 -carrying plasmids were only transmissible in the presence of the bla NDM-1 -carrying plasmid. The source of and direct links among them were not identified, suggesting a hospital transmission of a common multidrug resistant strain. Copyright © 2017 Elsevier Inc. All rights reserved.

[Self-perception of health care team leaders in Andalusia. A quantitative and qualitative study].
García-Romera, I; Danet, A; March-Cerdà, J C
To determine the perception and self-assessment on leadership among health care team leaders in Andalusia. Design: Exploratory descriptive study using quantitative and qualitative methodology, developed between 2013 and 2015, using a questionnaire and semi-structured interviews. Andalusia. All health managers from the Primary Care Management Units and Health Management Areas of the Departments of Paediatrics, Emergency and Internal Medicine, for the quantitative study. A purposive sample of 24 health managers was used for the qualitative study. Descriptive statistical study and bivariate analysis of comparison of means. Content analysis of the semi-structured interviews: Codification, category tree, and triangulation of results. The best self-assessment dimension relates to support, and the worst to considering oneself as a 'good leader'. The definition of a 'good leader' includes: Honesty, trust, and attitudes of good communication, closeness, appreciation, and reinforcement of the health team members. Different leadership styles were perceived. Main difficulties for leadership are related to the economic crisis and the management of personal conflicts. Health managers describe an adaptive leadership style, based on personal and professional support, and using communication as the main cohesive element for the team project. More studies on leaders' perspectives are important, in order to better understand their experiences, needs and expectations. Copyright © 2016 SECA. Publicado por Elsevier España, S.L.U.

This study explored the dynamics related to a leadership development programme and their impact on the clinical leader, the nursing team and the care-giving process. While there is a growing conviction about the need to invest in transformational leadership in nursing, further insight into the true complexity of leadership development and, more specifically, how leadership can make a difference in nursing and patient outcomes is essential. A single instrumental case study was conducted in a unit of a large academic hospital where a Clinical Leadership development Project (CLP) was implemented successfully. We used mixed methods with multiple sources of data to capture the complexity of leadership development. Data were collected through individual interviews, focus groups and observation of participants. A purposive sample of 17 participants representing a wide variety of team members has permitted data saturation. The data were categorized and conceptualized and finally organized into a framework describing leadership development on the unit and its impact on the leader, the nursing team and the care-giving process. Leadership development is an ongoing, interactive process between the clinical leader and the co-workers. The head nurse became more effective in areas of self-awareness, communication skills, performance and vision. The nursing team benefited because more effective leadership promoted effective communication, greater responsibility, empowerment and job clarity. Improved clinical leadership seemed also to influence patient-centred communication, continuity of care and interdisciplinary collaboration. The results of the study give more insight into the processes underlying the leader's progress towards attaining a transformational leadership style and its impact on the team members. The impact of leadership on the care-giving process, however, remains difficult to describe. The interactive nature of leadership development makes CLP a challenge for the

The health educator as a team leader in primary health care.
Brieger, W R; Ramakrishna, J
1986-01-01
Health teams naturally vary in size and composition according to their goals and objectives. Leadership of these teams should also be based on these goals. The goals of community-based primary health care, local involvement, cultural relevance, effective use of local resources, imply an important leadership role for health educators. The experience in the Ibarapa Local Government Area in Nigeria shows that health educators can be effective leaders in guiding a primary health care work group through various stages of program development. The use of a flexible, contractual model of team formation fits in well with the health educator's abilities to coordinate various program inputs and serve as mediator between professionals and the communities they serve. The ultimate mark of the health educator's leadership skills is the incorporation of community members into the health team.

The resident physician as leader within the healthcare team.
Sonnenberg, Lyn Kathryn; Pritchard-Wiart, Lesley; Busari, Jamiu
2018-05-08
Purpose The purpose of this study was to explore inter-professional clinicians' perspectives on resident leadership in the context of inter-professional teams and to identify a definition for leadership in the clinical context. In 2015, CanMEDS changed the title of one of the core competencies from manager to leader. The shift in language was perceived by some as returning to traditional hierarchical and physician-dominant structures. The resulting uncertainty has resulted in a call to action to not only determine what physician leadership is but to also determine how to teach and assess it. Design/methodology/approach Focus groups and follow-up individual interviews were conducted with 23 inter-professional clinicians from three pediatric clinical service teams at a large, Canadian tertiary-level rehabilitation hospital. Qualitative thematic analysis was used to inductively analyze the data. Findings Data analysis resulted in one overarching theme: leadership is collaborative - and three related subthemes: leadership is shared; leadership is summative; and conceptualizations of leadership are shifting. Research limitations/implications Not all members of the three inter-professional teams were able to attend the focus group sessions because of scheduling conflicts. Participation of additional clinicians could have, therefore, affected the results of this study. The study was conducted locally at a single rehabilitation hospital, among Canadian pediatric clinicians, which highlights the need to explore conceptualization of leadership across different contexts. Practical implications There is an evident need to prepare physicians to be leaders in both their daily clinical and academic practices. Therefore, more concerted efforts are required to develop leadership skills among residents. The authors postulate that continued integration of various inter-professional disciplines during the early phases of training is essential to foster collaborative leadership and

New Delhi MBL (NDM) is a type of carbapenemase; 20 variants of NDM have been identified to date. We have found a new variant of NDM, NDM-21, and describe it here. A carbapenem-resistant Escherichia coli was subjected to WGS using an Illumina X10 sequencer to identify the antimicrobial resistance genes and its ST. The gene encoding the new variant of NDM was cloned into E. coli DH5α, with blaNDM-5 being cloned as the control. Transformants were tested for susceptibility to carbapenems. Mating was performed to obtain the plasmid carrying the new blaNDM gene and the complete plasmid sequence was obtained using long-read MinION sequencing. The E. coli isolate belonged to ST617 and phylogenetic group A. It had a gene encoding NDM-21, a new NDM variant. NDM-21 differs from NDM-5 by a Gly-to-Ser amino acid substitution at position 69 (G69S). NDM-21 retains the same activity against carbapenems as NDM-5. blaNDM-21 is carried by a 46.1 kb IncX3 plasmid, which is self-transmissible, and is located in a complex genetic context as blaNDM-5. The isolate also carried blaCTX-M-55, which encodes an ESBL conferring resistance to aztreonam (which completed its resistance to all clinically available β-lactams), and rmtB, which mediates high-level resistance to aminoglycosides, on an IncFII plasmid. A new NDM variant has been identified and blaNDM-21 has evolved from blaNDM-5 on an IncX3 plasmid.

Objectives: To describe the genetic environment, transferability, and antibiotic susceptibility of one clinical Klebsiella pneumoniae isolate harboring both bla OXA-48 and bla NDM-1 on different plasmids from a Chinese hospital. Methods: The isolate was subjected to antimicrobial susceptibility testing and multilocus sequence typing using Etest and PCR. The plasmids harboring bla OXA-48 and bla NDM-1 were analyzed through conjugation experiments, S1-nuclease pulsed-field gel electrophoresis, and hybridization with specific probes. Plasmid DNA was sequenced using Pacbio RS II and annotated using RAST. Results: K. pneumoniae RJ119, carrying both bla OXA-48 and bla NDM-1 , was resistant to almost all carbapenems, cephalosporins, fluoroquinolone, and aminoglycosides and belonged to ST307. bla OXA-48 was located on a 61,748-bp IncL/M conjugative plasmid, which displayed overall nucleotide identity (99%) to pKPN-E1-Nr.7. bla NDM-1 was located on a 335,317-bp conjugative plasmid, which was a fusion of a bla NDM-1 -harboring InA/C plasmid pNDM-US (140,825 bp, 99% identity) and an IncFIB plasmid pKPN-c22 (178,563 bp, 99% identity). The transconjugant RJ119-1 harboring bla NDM-1 was susceptible to carbapenem, and there was an insertion of IS 10 into the bla NDM-1 gene. Conclusion: This is the first report of the coexistence of bla OXA-48 and bla NDM-1 in one K. pneumoniae clinical isolate in China. OXA-48 in RJ119 contributed to the majority to its high resistance to carbapenems, whereas NDM-1 remained unexpressed, most likely due to the insertion of IS 10 . Our results provide new insight for the relationship between genetic diagnosis and clinical treatment. They also indicate that increased surveillance of bla OXA-48 is urgently needed in China.

Interview: Mr. Stephen Chee, team leader, UNFPA country support team (CST) for the South Pacific.
1993-09-01
The UNFPA country support team (CST) for the South Pacific is the action-arm at the regional level of the new Technical Support Services arrangement introduced by the agency. Operational since April 1993, the CST currently covers the following Pacific island countries or territories: the Cook Islands, the Federated States of Micronesia, Fiji, Kiribati, Marshall Islands, Nauru, Niue, Palau, Papua New Guinea, Samoa, Solomon Islands, Tokelau, Tonga, Tuvalu, and Vanuatu. The CST office is located in Suva, Fiji, with the main goal of strengthening national capacity and building self-reliance in the countries of the region. The office in Suva is currently staffed by six highly qualified advisors with extensive experience in the population and related fields; two more advisors are expected to join the Team in early 1994. The Team is well equipped to provide countries and territories of the region with a wide range of technical support services ranging from ad hoc technical advisory services to the conceptualization and development of comprehensive population policies and programs. Services are offered in the areas of basic data collection, processing, and research in population dynamics; population policy formulation, evaluation, and implementation; family planning and maternal-child health; information, education, and communication; women in population and development; and population program management. The team also plays an advocacy role in mainstreaming population concerns into the programs and activities of international, regional, and national organizations. The team leader responds to questions about population problems experienced by the countries served, the scope of UNFPA assistance to country governments in the subregion, the importance of population information in the subregion, and how Asia-Pacific POPIN may help the team and countries served.

External leaders continue to be an important source of influence even when teams are empowered, but it is not always clear how they do so. Extending research on structurally empowered teams, we recognize that teams' external leaders are often responsible for multiple teams. We adopt a multilevel approach to model external leader influences at both the team level and the external leader level of analysis. In doing so, we distinguish the influence of general external leader behaviors (i.e., average external leadership) from those that are directed differently toward the teams that they lead (i.e., relative external leadership). Analysis of data collected from 451 individuals, in 101 teams, reporting to 25 external leaders, revealed that both relative and average external leadership related positively to team empowerment. In turn, team empowerment related positively to team performance and member job satisfaction. However, while the indirect effects were all positive, we found that relative external leadership was not directly related to team performance, and average external leadership evidenced a significant negative direct influence. Additionally, relative external leadership exhibited a significant direct positive influence on member job satisfaction as anticipated, whereas average external leadership did not. These findings attest to the value in distinguishing external leaders' behaviors that are exhibited consistently versus differentially across empowered teams. Implications and future directions for the study and management of external leaders overseeing multiple teams are discussed.

The location of the repressor gene, blaI, for the beta-lactamase gene blaP of Bacillus licheniformis 749, on the 5' side of blaP, was confirmed by sequencing the bla region of the constitutive mutant 749/C. An amber stop codon, likely to result in a nonfunctional truncated repressor, was found at codon 32 of the 128 codon blaI open reading frame (ORF) located 5' to blaP. In order to study the DNA binding activity of the repressor, the structural gene for blaI, from strain 749, with its ribosome binding site was expressed using a two plasmid T7 RNA polymerase/promotor system (S. Tabor and C. C. Richardson. Proc. Natl. Acad. Sci. 82, 1074-1078 (1985). Heat induction of this system in Escherichia coli K38 resulted in the production of BlaI as 5-10% of the soluble cell protein. Repressor protein was then purified by ammonium sulfate fractionation and cation exchange chromatography. The sequence of the N-terminal 28 amino acid residues was determined and was as predicted from the DNA. Binding of BlaI to DNA was detected by the slower migration of protein DNA complexes during polyacrylamide gel electrophoresis. BlaI was shown to selectively bind DNA fragments carrying the promoter regions of blaI and blaP. Images PMID:3498148

: The perceived benefits of rapid response teams (RRTs) influence whether RRTs are used and sustained. Perceived benefits are particularly important to sustaining RRTs when limited RRT data are shared with organizational members. Nurse leaders' perceptions of the benefits of RRTs likely influence their support, which is crucial for sustained RRT use. The perceptions of RRT members and end users similarly will affect use. But little is known regarding the perceptions of nurse leaders, RRT members, and RRT users in this regard.This study sought to explore and compare the perceptions of nurse leaders, RRT members, and RRT users regarding the benefits of RRTs.A qualitative, multiple-case study design was used. Semistructured interviews were conducted with nurse leaders, RRT members, and RRT users at four community hospitals, as part of a larger mixed-methods study examining RRT sustainability. Purposive and snowball sampling were used. Recruitment strategies included e-mail and listserv announcements, on-site presentations, direct personal contact, and a study flyer.All participants reported perceiving various ways that RRTs benefit the organization, staff members, and patients. Variations in the benefits perceived were observed between the three participant groups. Nurse leaders' perceptions tended to focus on macro-level benefits. RRT members emphasized the teaching and learning opportunities that RRTs offer. RRT users focused on the psychological support that RRTs can provide.Both similarities and differences were found between nurse leaders, RRT members, and RRT users regarding their perceptions of RRT benefits. Differences may be indicative of organizations' information-sharing processes; of variation in the priorities of nurse leaders, RRT members, and RRT users; and of the challenges nurses face daily in their work environments. Future research should investigate whether the perceived benefits of RRTs are borne out in actuality, as well as the relationships

ABSTRACT The extended-spectrum-β-lactamase (ESBL)- and Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae represent serious and urgent threats to public health. In a retrospective study of multidrug-resistant K. pneumoniae, we identified three clinical isolates, CN1, CR14, and NY9, carrying both blaCTX-M and blaKPC genes. The complete genomes of these three K. pneumoniae isolates were de novo assembled by using both short- and long-read whole-genome sequencing. In CR14 and NY9, blaCTX-M and blaKPC were carried on two different plasmids. In contrast, CN1 had one copy of blaKPC-2 and three copies of blaCTX-M-15 integrated in the chromosome, for which the blaCTX-M-15 genes were linked to an insertion sequence, ISEcp1, whereas the blaKPC-2 gene was in the context of a Tn4401a transposition unit conjugated with a PsP3-like prophage. Intriguingly, downstream of the Tn4401a-blaKPC-2-prophage genomic island, CN1 also carried a clustered regularly interspaced short palindromic repeat (CRISPR)-cas array with four spacers targeting a variety of K. pneumoniae plasmids harboring antimicrobial resistance genes. Comparative genomic analysis revealed that there were two subtypes of type I-E CRISPR-cas in K. pneumoniae strains and suggested that the evolving CRISPR-cas, with its acquired novel spacer, induced the mobilization of antimicrobial resistance genes from plasmids into the chromosome. The integration and dissemination of multiple copies of blaCTX-M and blaKPC from plasmids to chromosome depicts the complex pandemic scenario of multidrug-resistant K. pneumoniae. Additionally, the implications from this study also raise concerns for the application of a CRISPR-cas strategy against antimicrobial resistance. PMID:28438939

Eighty pilots participated in a study of variables influencing the transfer process. Posttraining performance was assessed in a flight simulation under 1 of 2 conditions. Those in the maximum performance condition were made aware of the skill to be assessed and the fact that their teammates were confederates, whereas those in the typical performance condition were not. The results indicated that (a) simulator ratings correlated with a measure of transfer to the cockpit for those in the typical condition only; (b) team leader support, manipulated in a pretask brief, moderated the disparity between maximum and typical performance; (c) team climate mediated the impact of support on performance in the typical condition; (d) those with a stronger predisposition toward the trained skill viewed their climate as more supportive; and (e) perceptions of team climate were better predictors of performance for those with a more external locus of control.

There is widespread use of clinical information systems in intensive care units however, the evidence to support electronic handover is limited. The study aim was to assess the barriers and facilitators to use of an electronic minimum dataset for nursing team leader shift-to-shift handover in the intensive care unit prior to its implementation. The study was conducted in a 21-bed medical/surgical intensive care unit, specialising in cardiothoracic surgery at a tertiary referral hospital, in Queensland, Australia. An established tool was modified to the intensive care nursing handover context and a survey of all 63 nursing team leaders was undertaken. Survey statements were rated using a 6-point Likert scale with selections from 'strongly disagree' to 'strongly agree', and open-ended questions. Descriptive statistics were used to summarise results. A total of 39 team leaders responded to the survey (62%). Team leaders used general intensive care work unit guidelines to inform practice however they were less familiar with the intensive care handover work unit guideline. Barriers to minimum dataset uptake included: a tool that was not user friendly, time consuming and contained too much information. Facilitators to minimum dataset adoption included: a tool that was user friendly, saved time and contained relevant information. Identifying the complexities of a healthcare setting prior to the implementation of an intervention assists researchers and clinicians to integrate new knowledge into healthcare settings. Barriers and facilitators to knowledge use focused on usability, content and efficiency of the electronic minimum dataset and can be used to inform tailored strategies to optimise team leaders' adoption of a minimum dataset for handover.

Adolescent alcohol drinking increases the risk for alcohol-use disorder in adulthood. Yet, the changes in adult neural function resulting from adolescent alcohol drinking remain poorly understood. We hypothesized that adolescent alcohol drinking alters basolateral amygdala (BLA) function, making alcohol drinking BLA-dependent in adulthood. Male, Long Evans rats were given voluntary, intermittent access to alcohol (20% ethanol) or a bitter, isocaloric control solution, across adolescence. Half of the rats in each group received neurotoxic BLA lesions. In adulthood, all rats were given voluntary, intermittent access to alcohol. BLA lesions reduced adult alcohol drinking in rats receiving adolescent access to alcohol, but not in rats receiving adolescent access to the control solution. The effect of the BLA lesion was most apparent in high alcohol drinking adolescent rats. The BLA is essential for fear learning and is hyper-active in anxiety disorders. The results are consistent with adolescent heavy alcohol drinking inducing BLA hyper-activity, providing a neural mechanism for comorbid alcohol use disorder and anxiety disorders. PMID:29135933

This study aimed to assess the molecular basis of the resistance to carbapenems in clinical isolates of Pseudomonas aeruginosa recovered from a tertiary-level health facility in San José, Costa Rica. A total of 198 non-duplicated isolates were evaluated for their susceptibility to β-lactams, aminoglycosides and fluoroquinolones. The production of metallo-β-lactamases (MBLs), the presence of MBL encoding genes (blaIMP, blaVIM and blaGIM-1) and the occurrence of these genes within class 1 integrons were investigated. In addition, an ERIC2 PCR fingerprinting method was used to elucidate the distribution of the detected MBL genes within the strain collection. Of the 198 isolates tested, 125 (63.1 %) were categorized as carbapenem-resistant. The majority (88.8 %) of the carbapemen-resistant isolates also showed resistance to ceftazidime, cefepime, aztreonam, ticarcillin/clavulanic acid, amikacin, gentamicin, tobramycin, ciprofloxacin and gatifloxacin. Among the carbapenem-resistant isolates, 102 (81.6 %) showed MBL activity. Strikingly, both blaIMP and blaVIM genes were simultaneously detected in most (94.1 %) of the 102 MBL producers. Five carbapenem-resistant MBL producers were positive only for blaIMP genes. Almost 70 % of the isolates examined harboured the intI1 gene, accompanied by the sul1 and qacEΔ1 genes in 136 (99 %) and 122 (89 %) isolates, respectively. The majority (94.4 %) of the carbapenem-resistant isolates carried the intI1 gene, in contrast to 26 % of the carbapenem-susceptible isolates. Ninety-three out of 96 (96.9 %) isolates carrying both blaIMP and blaVIM genes also harboured the intI1, sul1 and qacEΔ1 genes. Gene cassettes from carbapenem-susceptible and MBL-negative carbapenem-resistant isolates encoded aminoglycoside-resistance enzymes (aadA2, aadA4 and aadA6) as well as orfD and qacF genes. RAPD analysis distributed 126 of the isolates in 29 clusters. Eighty of the 90 blaIMP (+) blaVIM (+) isolates were sorted into 16

We screened 364 Enterobacteriaceae for carbapenem resistance between 2012 and 2013 and detected four carbapenem-resistant K. pneumoniae isolates from three different patients. We used whole genome sequencing to determine the antibiotic resistance profiles and confirmed the presence of carbapenemase genes by multiplex PCR. We used multilocus sequence typing and PCR-based replicon typing to genetically characterize the carbapenem-resistant isolates. The carbapenemase gene blaNDM was detected in K. pneumoniae isolates from two patients. The first patient had ventilator-associated pneumonia and lumbar shunt infection from K. pneumoniae ST273 carrying blaNDM-7. The second patient had asymptomatic genitourinary colonization with K. pneumoniae ST656 carrying blaNDM-1. The third patient had a gluteal abscess with K. pneumoniae ST1 that did not carry a carbapenemase gene, but did carry blaDHA-1, blaOXA-1, and blaSHV-1. In this study, we report the first cases of blaNDM-carrying pathogens in the Philippines and add to the growing evidence of the worldwide spread of ST273 and NDM-7, a more efficient carbapenem hydrolyzer than NDM-1.

Interpersonal team leadership skills.
Nelson, M
1995-05-01
To say that a team leader's job is a tough one is certainly not saying enough. It is up to the team leader to manage a group of people to be individuals but yet work as a team. The team leader must keep the peace and yet create a revolution with this group all at the same time. The good leader will require a lot of education, training, and tons of practical application to be a success. The good news, however, is that the team leader's job is a rewarding one, one that they'll always feel good about if they do it right. How many of us get the opportunity to take a group of wonderful, thinking individual minds and pull from them ideas that a whole team can take to success? Yes, the job is indeed tough, but the paybacks are many.

Leading team learning: what makes interprofessional teams learn to work well?
Chatalalsingh, Carole; Reeves, Scott
2014-11-01
This article describes an ethnographic study focused on exploring leaders of team learning in well-established nephrology teams in an academic healthcare organization in Canada. Employing situational theory of leadership, the article provides details on how well established team members advance as "learning leaders". Data were gathered by ethnographic methods over a 9-month period with the members of two nephrology teams. These learning to care for the sick teams involved over 30 regulated health professionals, such as physicians, nurses, social workers, pharmacists, dietitians and other healthcare practitioners, staff, students and trainees, all of whom were collectively managing obstacles and coordinating efforts. Analysis involved an inductive thematic analysis of observations, reflections, and interview transcripts. The study indicated how well established members progress as team-learning leaders, and how they adapt to an interprofessional culture through the activities they employ to enable day-to-day learning. The article uses situational theory of leadership to generate a detailed illumination of the nature of leaders' interactions within an interprofessional context.

Peer led team learning in introductory biology: effects on peer leader critical thinking skills.
Snyder, Julia J; Wiles, Jason R
2015-01-01
This study evaluated hypothesized effects of the Peer-Led Team Learning (PLTL) instructional model on undergraduate peer leaders' critical thinking skills. This investigation also explored peer leaders' perceptions of their critical thinking skills. A quasi-experimental pre-test/post-test with control group design was used to determine critical thinking gains in PLTL/non-PLTL groups. Critical thinking was assessed using the California Critical Thinking Skills Test (CCTST) among participants who had previously completed and been successful in a mixed-majors introductory biology course at a large, private research university in the American Northeast. Qualitative data from open-ended questionnaires confirmed that factors thought to improve critical thinking skills such as interaction with peers, problem solving, and discussion were perceived by participants to have an impact on critical thinking gains. However, no significant quantitative differences in peer leaders' critical thinking skills were found between pre- and post-experience CCTST measurements or between experimental and control groups.

Despite increasing demand for structured processes to guide clinical handover, nursing handover tools are limited in the intensive care unit. The study aim was to identify key items to include in a minimum dataset for intensive care nursing team leader shift-to-shift handover. This focus group study was conducted in a 21-bed medical/surgical intensive care unit in Australia. Senior registered nurses involved in team leader handovers were recruited. Focus groups were conducted using a nominal group technique to generate and prioritise minimum dataset items. Nurses were presented with content from previous team leader handovers and asked to select which content items to include in a minimum dataset. Participant responses were summarised as frequencies and percentages. Seventeen senior nurses participated in three focus groups. Participants agreed that ISBAR (Identify-Situation-Background-Assessment-Recommendations) was a useful tool to guide clinical handover. Items recommended to be included in the minimum dataset (≥65% agreement) included Identify (name, age, days in intensive care), Situation (diagnosis, surgical procedure), Background (significant event(s), management of significant event(s)) and Recommendations (patient plan for next shift, tasks to follow up for next shift). Overall, 30 of the 67 (45%) items in the Assessment category were considered important to include in the minimum dataset and focused on relevant observations and treatment within each body system. Other non-ISBAR items considered important to include related to the ICU (admissions to ICU, staffing/skill mix, theatre cases) and patients (infectious status, site of infection, end of life plan). Items were further categorised into those to include in all handovers and those to discuss only when relevant to the patient. The findings suggest a minimum dataset for intensive care nursing team leader shift-to-shift handover should contain items within ISBAR along with unit and patient specific

The purpose of this study was to examine the effects of coaching behaviours provided by peers and by the leader on the emotions experienced by interprofessional health and social care teams and on members' satisfaction with the team, as well as on team performance. Data were obtained from a survey among 344 employees working in 52 interprofessional health and social care teams from nine Portuguese organizations. The results show that leader coaching and peer coaching have a positive effect on the level of team members' satisfaction with the team and on positive emotions, and a negative effect on negative emotions. Furthermore, coaching provided by peers presents a positive effect on team performance as assessed by the leader of the team. Our findings put forward the importance of engaging in coaching behaviours to promote quality of the team experience, as well as the achievement of team performance objectives. Further studies should explore how coaching behaviours impact the patient, whose well-being is the ultimate objective of a team in the health and social care system, namely in terms of the patient's perception of quality care or patient outcomes.

Employee radical creativity critically depends on substantive informational resources from others across the wider organization. We propose that the social network ties of employees' immediate leaders assume a central role in garnering these resources, thereby fostering their employees' radical creativity both independent of and interactively with employees' own network ties. Drawing on data from 214 employees working in 30 teams of a public technology and environmental services organization, we find that team leaders' betweenness centrality in the idea network within their teams as well as among their peer leaders provides creative benefits beyond employees' own internal and external ties. Further, employees' and leaders' ties within and external to the team interactively predict employee radical creativity. Implications for theory and practice are discussed.

Background Due to the overuse of antibiotics in livestock as a growth-promoting agent, the emergence of multi-antibiotic resistant bacteria is becoming a concern. Objectives In this study, we aimed to detect the presence and discover the molecular determinants of foodborne bacteria in retail sausages resistant towards the antibacterial agent amoxicillin-clavulanate. Methods Two grams of sausages were chopped into small pieces and transferred into sterile Luria-Bertani (LB) enrichment broths overnight before they were plated on MacConkey agar petri dishes. The bacteria isolated were then screened for amoxicillin-clavulanate resistance, and an antimicrobial susceptibility test of each isolate was performed by using the disc diffusion method. Double synergy and phenotypic tests were carried out to detect the presence of extended spectrum β-lactamase (ESBL). API 20E kit was used to identify the Enterobacteriaceae. All isolates were further examined by polymerase chain reaction (PCR) for resistant genes blaOXA-1, blaOXA-10, plasmid-mediated AmpC (blaCMY and blaDHA), and the chromosome-mediated AmpC, Sul1, blaTEM, and blaSHV genes. Results A total of 18 amoxicillin-clavulanate resistant isolates were obtained from seven different types of retail sausages. Only half of them were identified as Enterobacteriaceae, but none were ESBL-producers. All the 18 isolated strains demonstrated resistance towards amoxicillin-clavulanate, penicillin and oxacillin (100%), cefotaxime (71.4%), cefpodoxime (66.7%), and ampicillin (83.3%). blaTEM was the most frequently detected β-lactamase gene. Both plasmid- and chromosomal-bound blaTEM genes were detected in all of the isolated Enterobacteriaceae. blaSHV and Sul1 accounted for 22.2% and 11.1% of the amoxicillin-clavulanate resistant isolates, respectively, whereas blaAMPC, blaCMY, blaDHA, blaOXA-1, and blaOXA-10 were not found in any of the isolates. The only one ESBL-producing bacteria detected in this study was Chryseobacterium

This study uses the naturalistic decision-making (NDM) perspective to examine how Dutch forensic team leaders (i.e., the officers in charge of criminal forensic research from the crime scene until the use of laboratory assistance) make decisions in real-life settings and identifies the contextual factors that might influence those decisions. First, a focus group interview was conducted to identify four NDM mechanisms in day-to-day forensic decision making. Second, a serious game was conducted to examine the influence of three of these contextual mechanisms. The results uncovered that forensic team leaders (i) were attracted to obtain further information when more information was initially made available, (ii) were likely to devote more attention to emotionally charged cases, and (iii) used not only forensic evidence in the decision making but also tactical, unverified information of the police inquiry. Interestingly, the measured contextual influences did not deviate significantly from a control group of laypeople. © 2011 American Academy of Forensic Sciences.

For globally distributed teams charged with innovation, member contributions to the team are crucial for effective performance. Prior research, however, suggests that members of globally distributed teams often feel isolated and excluded from their team's activities and decisions. How can leaders of such teams foster member inclusion in team decisions? Drawing on leader-member exchange (LMX) theory, we propose that for distributed teams, LMX and communication frequency jointly shape member influence on team decisions. Findings from a test of our hypotheses using data from 40 globally distributed teams suggest that LMX can enhance member influence on team decisions when it is sustained through frequent leader-member communication. This joint effect is strengthened as team dispersion increases. At the team level, member influence on team decisions has a positive effect on team innovation. (c) 2012 APA, all rights reserved.

To study the prevalence of blaVIM and blaIMP genes in metallo-β-lactamase (MBL)-producing burn isolates of Pseudomonas aeruginosa in relation with AmpC and extended-spectrum β-lactamase (ESBL) production. Thirty-two carbapenem-resistant MBL-producing P aeruginosa burn isolates from Shahid Motahari Burn Hospital in Tehran were employed. Antibiotic susceptibility was determined to 13 antibiotics including imipenem and meropenem by disk diffusion. AmpC and ESBL production was detected by the AmpC disk test and combined disk diffusion assay, respectively, blaIMP and blaVIM gene carriage was shown by polymerase chain reaction and type-specific primers. AmpC production was observed in 81% and ESBL production was detected in 12.5% of the isolates. blalMP carriage was observed in 56.25% and blaVIM gene in 46.8% of the isolates. Surprisingly, 43.5% of the isolates carried both blalMP and blaviM genes. We think that this is the first report on the cocarriage of blalMP and blavIM in P aeruginosa. There was also a strong association between MBL gene carriage and AmpC β-lactamase production.

Profile of an excellent nurse manager: identifying and developing health care team leaders.
Kallas, Kathryn D
2014-01-01
The purpose of this research was to identify the profile of an excellent nurse manager who can lead effective health care teams. Leadership attributes and competencies that characterize an excellent nurse manager and tools to identify them are lacking in the literature but are required to efficiently and effectively address the growing shortage of registered nurses (RNs) in health care team leadership roles and the critical linkage of these roles to patient outcomes. A profile of an excellent nurse manager was developed on the basis of the responses of nurse managers across the United States who had been identified as excellent or competent by chief nurse executive assessment or/and the Nurse Manager Ability, Leadership, and Support of Nurses staff survey to the Kouzes and Posner Leadership Practices Inventory: Self Instrument. Statistically significant distinctions exist between nurse managers who are excellent and those who are competent as assessed by the Five Practices of Exemplary Leadership, which together comprise the profile of an excellent nurse manager. The Kouzes and Posner Leadership Practices Inventory: Self Instrument can be used to identify, recruit, and develop RNs in the nurse manager role as excellent leaders of effective health care teams.

Carbapenem resistant Pseudomonas aeruginosa is a serious cause of nosocomial infections. The main purpose of the study is to determine the prevalence rate of imipenem resistant Pseudomonas aeruginosa carrying metallo-ß-lactamase (MBL) genes. 236 Pseudomonas aeruginosa isolates were collected from teaching hospitals of Ahvaz University of Medical Sciences during a period of 9 months in 2012. These strains were identified using conventional microbiological tests. The susceptibility of isolates to antibiotics were assessed using disk diffusion test. The IMP-EDTA combination disk phenotypic test was performed for detection of MBL producing strains. Finally, polymerase chain reaction (PCR) was performed to detect MBL genes, bla IMP-1, bla VIM-2 and bla SPM-1 in imipenem resistant strains. Out of 236 examined isolates, 122 isolates (51.4%) were resistant to imipenem. The IMP-EDTA combination test showed that among 122 imipenem resistant strains, 110 strains (90%) were phenotipically MBL producers. Additionally, the results of PCR method showed that 2 strains (1.6%) and 67strains (55%) of imipenem resistant Pseudomonas aeruginosa isolates contained bla VIM-2 and bla IMP-1 genes respectively. No SPM-1gene was found in the examined samples. Resistance of P. aeruginosa isolates to imipenem due to MBL enzymes is increasing in Ahavaz. Because of clinical significance of this kind of resistance, rapid detection of MBL producing strains and followed by appropriate treatment is necessary to prevent the spreading of these organisms.

The University of Arizona's Collaboration to Advance Teaching Technology and Science (CATTS) program sponsored by the National Science Foundation has found a successful way to unite public and charter school students and teachers, university science outreach programs, graduate and undergraduate students, and university faculty for the betterment of science education. A key aspect of this success has been the ability of the project to assist stakeholders in understanding the different cultural perspectives of all of the participants. The success of this program has led us to create a template for a professional development and support program emphasizing the degree of cross-cultural understanding appropriate for today's multinational photonics industry. This template is designed to give future photonics technical, managerial, and manufacturing leaders training in a variety of areas that can enhance their productivity and ability to lead teams. The design would be appropriate for photonics research and development teams, sales and marketing teams, teams with diverse members new college hires, and newly emplaced managers. This education template would also be appropriate for students in photonics industry technician and graduate- level programs. This type of program is not a substitute for other forms of professional managerial training, but rather augments such programs with material that can aid in a more global perspective.

Bla g 2 is a major indoor cockroach allergen associated with the development of asthma. Antigenic determinants on Bla g 2 were analyzed by mutagenesis based on the structure of the allergen alone and in complex with monoclonal antibodies that interfere with IgE antibody binding. The structural analysis revealed mechanisms of allergen-antibody recognition through cation-π interactions. Single and multiple Bla g 2 mutants were expressed in Pichia pastoris and purified. The triple mutant K132A/K251A/F162Y showed an ∼100-fold reduced capacity to bind IgE, while preserving the native molecular fold, as proven by x-ray crystallography. This mutant was still able to induce mast cell release. T-cell responses were assessed by analyzing Th1/Th2 cytokine production and the CD4+ T-cell phenotype in peripheral blood mononuclear cell cultures. Although T-cell activating capacity was similar for the KKF mutant and Bla g 2 based on CD25 expression, the KKF mutant was a weaker inducer of the Th2 cytokine IL-13. Furthermore, this mutant induced IL-10 from a non-T-cell source at higher levels that those induced by Bla g 2. Our findings demonstrate that a rational design of site-directed mutagenesis was effective in producing a mutant with only 3 amino acid substitutions that maintained the same fold as wild type Bla g 2. These residues, which were involved in IgE antibody binding, endowed Bla g 2 with a T-cell modulatory capacity. The antigenic analysis of Bla g 2 will be useful for the subsequent development of recombinant allergen vaccines. PMID:26644466

Leader succession often occurs during organizational change processes, but the implications of leader succession, in terms of reactions to the change, rarely have been investigated. Employee attitudes and behaviors during organizational change may be influenced jointly by a former leader who recently has transitioned out of the team and the new leader who recently has transitioned into it. We predict an interaction between former and new leaders' transformational leadership on employees' behavioral resistance to and support for change. On the basis of contrast effect theory, a highly transformational former leader constrains the potential effectiveness of the new leader, but a former leader low in transformational leadership enhances this potential effectiveness. We also propose conditional indirect effects transmitted through commitment to the changing organization. Our research was conducted in a large Chinese hospitality organization that was implementing radical organizational change, during which virtually all aspects of processes and products are changed. We collected a 2-wave multisource data from employees who had recently experienced a leader succession and their newly assigned leaders. On the basis of a final sample of 203 employees from 22 teams, we found empirical support for the proposed interaction effects. The conditional indirect effects were also consistent with our expectations, but the effect on behavioral resistance to change was stronger than the effect on behavioral support for change.

The emergence of carbapenem resistance among Escherichia coli is a serious threat to public health. The objective of this study was to investigate resistance genes and clonality of carbapenem resistant E. coli in Iran. Between February 2015 and July 2016, a total of 32 non-duplicate E. coli isolates that were ertapenem resistant or intermediate (R/I-ETP) were collected from patient clinical or surveillance cultures (rectal swabs) at two university hospitals. Resistance genes were identified by PCR and sequencing. Conjugation experiments, PCR-based replicon typing, PFGE and multilocus sequence typing (MLST) were performed. PCR assays showed, among the 32 isolates, twenty-nine strains produced carbapenemase genes. The predominant carbapenemase was bla OXA-48 (82.8%), followed by bla NDM-1 (31%), bla NDM-7 (6.9%) and bla OXA-181 (3.4%). Seven of the bla NDM positive isolates co-harbored bla OXA-48 carbapenemases. The bla NDM and bla OXA-48 were found in IncA/C and IncL/M conjugative plasmids, respectively. The bla CTX-M-15 , qnrA and intI1 genes were also present in most isolates. The PFGE revealed genetic diversity among the 28 E. coli isolates, which belonged to six minor PFGE clusters and 14 isolates were singletons. The 26 isolates were distributed into 18 STs, of which two were dominant (ST648 and ST167). We identified one bla NDM-1 -positive ST131 E. coli isolates that harbor the bla CTX-M-15 and bla TEM genes. Horizontal transfer of IncA/C and IncL/M plasmids has likely facilitated the spread of the bla OXA-48 and bla NDM genes among E. coli. Their clonal diversity and the presence of faecal carriers in isolates suggest an endemic spread of OXA-48 and NDM. Therefore, it emphasizes the critical importance of monitoring and controlling the spread of carbapenem resistant E. coli. Copyright © 2017. Published by Elsevier B.V.

The spread of carbapenemase-producing Enterobacteriaceae (CPE) is a great problem of healthcare worldwide. Study of the spread for bla OXA-48-like genes coding epidemically significant carbapenemases among hospital pathogens is important for the regional and global epidemiology of antimicrobial resistance. Antibacterial resistant isolates of Klebsiella pneumoniae (n = 95) from 54 patients, P. mirabilis (n = 32) from 20 patients, Enterobacter aerogenes (n = 6) from four patients, and Enterobacter cloacae (n = 4) from four patients were collected from January, 2013 to October, 2014 in neurosurgical intensive care unit (ICU) of the Burdenko Neurosurgery Institute, Moscow. Characteristics of the isolates were done using susceptibility tests, PCR detection of the resistance genes, genotyping, conjugation, DNA sequencing, and bioinformatic analysis. Major strains under study were multi drug resistant (MDR), resistant to three or more functional classes of drugs simultaneously-98.9 % K. pneumoniae, 100 % P. mirabilis, one E. aerogenes isolate, and one E. cloacae isolate. Molecular-genetic mechanism of MDR in K. pneumoniae and P. mirabilis isolates were based on carrying of epidemic extended-spectrum beta-lactamase bla CTX-M-15 gene (87.2 and 90.6 % accordingly), carbapenemase bla OXA-48-like gene (55.3 and 23.3 % accordingly), and class 1 (54.8 and 31.3 % accordingly) and class 2 (90.6 % P. mirabilis) integrons. The bla OXA-48-like-positive K. pneumoniae were collected during whole two-year surveillance period, while P. mirabilis and Enterobacter spp. carrying bla OXA-48-like genes were detected only after four and 18 months after the research start, respectively. The bla OXA-48-like gene acquisition was shown for P. mirabilis isolates collected from five patients and for E. cloacae isolate collected from one patient during their stay in the ICU, presumably from bla OXA-48-like-positive K. pneumoniae.

Integrating leader-member exchange (LMX) research with role engagement theory (Kahn, 1990) and role system theory (Katz & Kahn, 1978), we propose a multilevel, dual process model to understand the mechanisms through which LMX quality at the individual level and LMX differentiation at the team level simultaneously affect individual and team performance. With regard to LMX differentiation, we introduce a new configural approach focusing on the pattern of LMX differentiation to complement the traditional approach focusing on the degree of LMX differentiation. Results based on multiphase, multisource data from 375 employees of 82 teams revealed that, at the individual level, LMX quality positively contributed to customer-rated employee performance through enhancing employee role engagement. At the team level, LMX differentiation exerted negative influence on teams' financial performance through disrupting team coordination. In particular, teams with the bimodal form of LMX configuration (i.e., teams that split into 2 LMX-based subgroups with comparable size) suffered most in team performance because they experienced greatest difficulty in coordinating members' activities. Furthermore, LMX differentiation strengthened the relationship between LMX quality and role engagement, and team coordination strengthened the relationship between role engagement and employee performance. Theoretical and practical implications of the findings are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Bla g 2 is a major indoor cockroach allergen associated with the development of asthma. Antigenic determinants on Bla g 2 were analyzed by mutagenesis based on the structure of the allergen alone and in complex with monoclonal antibodies that interfere with IgE antibody binding. The structural analysis revealed mechanisms of allergen-antibody recognition through cation-π interactions. Single and multiple Bla g 2 mutants were expressed in Pichia pastoris and purified. The triple mutant K132A/K251A/F162Y showed an ∼100-fold reduced capacity to bind IgE, while preserving the native molecular fold, as proven by x-ray crystallography. This mutant was still able to induce mast cell release. T-cell responses were assessed by analyzing Th1/Th2 cytokine production and the CD4(+) T-cell phenotype in peripheral blood mononuclear cell cultures. Although T-cell activating capacity was similar for the KKF mutant and Bla g 2 based on CD25 expression, the KKF mutant was a weaker inducer of the Th2 cytokine IL-13. Furthermore, this mutant induced IL-10 from a non-T-cell source at higher levels that those induced by Bla g 2. Our findings demonstrate that a rational design of site-directed mutagenesis was effective in producing a mutant with only 3 amino acid substitutions that maintained the same fold as wild type Bla g 2. These residues, which were involved in IgE antibody binding, endowed Bla g 2 with a T-cell modulatory capacity. The antigenic analysis of Bla g 2 will be useful for the subsequent development of recombinant allergen vaccines. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

ABSTRACT Carbapenem-resistant Enterobacter cloacae complex isolates submitted to a reference laboratory from 2010 to 2015 were screened by PCR for seven common carbapenemase gene groups, namely, KPC, NDM, OXA-48, VIM, IMP, GES, and NMC-A/IMI. Nineteen of the submitted isolates (1.7%) were found to harbor Ambler class A blaNMC-A or blaIMI-type carbapenemases. All 19 isolates were resistant to at least one carbapenem but susceptible to aminoglycosides, trimethoprim-sulfamethoxazole, tigecycline, and ciprofloxacin. Most isolates (17/19) gave positive results with the Carba-NP test for phenotypic carbapenemase detection. Isolates were genetically diverse by pulsed-field gel electrophoresis macrorestriction analysis, multilocus sequence typing, and hsp60 gene analysis. The genes were found in various Enterobacter cloacae complex species; however, blaNMC-A was highly associated with Enterobacter ludwigii. Whole-genome sequencing and bioinformatics analysis revealed that all NMC-A (n = 10), IMI-1 (n = 5), and IMI-9 (n = 2) producers harbored the carbapenemase gene on EludIMEX-1-like integrative mobile elements (EcloIMEXs) located in the identical chromosomal locus. Two novel genes, blaIMI-5 and blaIMI-6, were harbored on different IncFII-type plasmids. Enterobacter cloacae complex isolates harboring blaNMC-A/IMI-type carbapenemases are relatively rare in Canada. Though mostly found integrated into the chromosome, some variants are located on plasmids that may enhance their mobility potential. PMID:28223374

Human leader and robot follower team: correcting leader's position from follower's heading
NASA Astrophysics Data System (ADS)
Borenstein, Johann; Thomas, David; Sights, Brandon; Ojeda, Lauro; Bankole, Peter; Fellars, Donald
2010-04-01
In multi-agent scenarios, there can be a disparity in the quality of position estimation amongst the various agents. Here, we consider the case of two agents - a leader and a follower - following the same path, in which the follower has a significantly better estimate of position and heading. This may be applicable to many situations, such as a robotic "mule" following a soldier. Another example is that of a convoy, in which only one vehicle (not necessarily the leading one) is instrumented with precision navigation instruments while all other vehicles use lower-precision instruments. We present an algorithm, called Follower-derived Heading Correction (FDHC), which substantially improves estimates of the leader's heading and, subsequently, position. Specifically, FHDC produces a very accurate estimate of heading errors caused by slow-changing errors (e.g., those caused by drift in gyros) of the leader's navigation system and corrects those errors.

Characterization of Proteus mirabilis isolates harbouring bla OXA-58 with emphasis on the genetic environment of this resistance determinant. Strains of P. mirabilis ( n = 37) isolated from different patients were tested for the presence of bla OXA-58 . The genetic context of bla OXA-58 was determined by WGS of two strains and Sanger sequencing. Clonality of the strains was assessed by PFGE. Susceptibility testing was performed by microdilution according to EUCAST. Four strains isolated in different geographical regions of Germany were positive for bla OXA-58 , and WGS showed that this resistance gene was harboured on a plasmid. Sanger sequencing confirmed the presence of two nearly identical plasmids, 6219 and 6208 bp in size, in all four strains. Upstream of bla OXA-58 an IS Aba 3-like transposase gene was located. The P. mirabilis strains were not clonally related according to PFGE. MICs of meropenem for three of the strains were only just above the EUCAST breakpoint and the Carba NP test was positive for only two of the strains. To our knowledge, this is the first description of bla OXA-58 in the species P. mirabilis . The resistance gene is harboured by almost identical plasmids in strains not clonally related and from different geographical regions. Apart from an IS Aba 3-like transposase gene upstream of bla OXA-58 the genetic context is different from bla OXA-58 harboured on plasmids in the genus Acinetobacter . With MICs of meropenem well below the EUCAST breakpoint or only just above it and equivocal or false negative results from the Carba NP test, bla OXA-58 can be easily overlooked in P. mirabilis . © The Author 2017.

Although a growing body of research links leadership behavior to follower health, comparatively little is known about the health effects of being in the lead. This longitudinal study of 315 team members and 67 leaders examined the crossover of emotional exhaustion and work engagement from followers to leaders. Leader emotional self-efficacy was tested as a moderator in the crossover process. Multiple regression analyses revealed that followers' work engagement was positively related to leaders' work engagement eight months later, controlling for followers' tenure with the leader, leader gender, autonomy, workload, and work engagement at Time 1. Leaders' emotional self-efficacy did not moderate the crossover of work engagement. Followers' emotional exhaustion was not directly related to leaders' emotional exhaustion over time. We did find a significant interaction effect for follower emotional exhaustion and leader emotional self-efficacy. This study is the first to show that crossover of emotional exhaustion and work engagement can unfold over time from team members to leaders. Main theoretical implications lie in the finding that-in line with job demands-resources theory-followers' psychological states can pose a demand or resource for leaders, and influence their well-being. For practitioners, our results offer valuable insights regarding the design of organizational health interventions as well as leadership development measures.

Better team management--better team care?
Shelley, P; Powney, B
1994-01-01
Team building should not be a 'bolt-on' extra, it should be a well planned, integrated part of developing teams and assisting their leaders. When asked to facilitate team building by a group of NHS managers we developed a framework which enabled individual members of staff to become more effective in the way they communicated with each other, their teams and in turn within the organization. Facing the challenge posed by complex organizational changes, staff were able to use 3 training days to increase and develop their awareness of the principles of teamwork, better team management, and how a process of leadership and team building could help yield better patient care.

Background There is consensus about the importance of ‘recovery’ in mental health services, but the link between recovery orientation of mental health teams and personal recovery of individuals has been underresearched. Aims To investigate differences in team leader, clinician and service user perspectives of recovery orientation of community adult mental health teams in England. Method In six English mental health National Health Service (NHS) trusts, randomly chosen community adult mental health teams were surveyed. A random sample of ten patients, one team leader and a convenience sample of five clinicians were surveyed from each team. All respondents rated the recovery orientation of their team using parallel versions of the Recovery Self Assessment (RSA). In addition, service users also rated their own personal recovery using the Questionnaire about Processes of Recovery (QPR). Results Team leaders (n = 22) rated recovery orientation higher than clinicians (n = 109) or patients (n = 120) (Wald(2) = 7.0, P = 0.03), and both NHS trust and team type influenced RSA ratings. Patient-rated recovery orientation was a predictor of personal recovery (b = 0.58, 95% CI 0.31–0.85, P<0.001). Team leaders and clinicians with experience of mental illness (39%) or supporting a family member or friend with mental illness (76%) did not differ in their RSA ratings from other team leaders or clinicians. Conclusions Compared with team leaders, frontline clinicians and service users have less positive views on recovery orientation. Increasing recovery orientation may support personal recovery.

Reports of carbapenemase-producing Enterobacteriaceae in Africa remain rare and assess mostly blaOXA-48–producing isolates from Mediterranean countries and South Africa. We identified blaNDM-7–producing Enterobacteriaceae in Gabon in 2016. The isolates contained blaNDM-7 IncX3 plasmids that were unusual and similar to the one described in a colistin-resistant Klebsiella pneumoniae SZ04 isolate from China. PMID:28098536

The aim of this study was to assess the validity of a formative feedback instrument for leaders of simulated resuscitations. This is a prospective validation study with a fully crossed (person × scenario × rater) study design. The Concise Assessment of Leader Management (CALM) instrument was designed by pediatric emergency medicine and graduate medical education experts to be used off the shelf to evaluate and provide formative feedback to resuscitation leaders. Four experts reviewed 16 videos of in situ simulated pediatric resuscitations and scored resuscitation leader performance using the CALM instrument. The videos consisted of 4 pediatric emergency department resuscitation teams each performing in 4 pediatric resuscitation scenarios (cardiac arrest, respiratory arrest, seizure, and sepsis). We report on content and internal structure (reliability) validity of the CALM instrument. Content validity was supported by the instrument development process that involved professional experience, expert consensus, focused literature review, and pilot testing. Internal structure validity (reliability) was supported by the generalizability analysis. The main component that contributed to score variability was the person (33%), meaning that individual leaders performed differently. The rater component had almost zero (0%) contribution to variance, which implies that raters were in agreement and argues for high interrater reliability. These results provide initial evidence to support the validity of the CALM instrument as a reliable assessment instrument that can facilitate formative feedback to leaders of pediatric simulated resuscitations.

Leadership by health care professionals is likely to vary because of differences in the social contexts within which they are situated, socialization processes and societal expectations, education and training, and the way their professions define and operationalize key concepts such as teamwork, collaboration, and partnership. This research examines the effect of the nurse and physician leaders on interdependence and encounter preparedness in chronic disease management practice groups. The aim of this study was to examine the effect of complementary leadership by nurses and physicians involved in jointly producing a health care service on care team functioning. The design is a retrospective observational study based on survey data. The unit of analysis is heart failure care groups in U.S. Veterans Health Administration medical centers. Survey and administrative data were collected in 2009 from 68 Veterans Health Administration medical centers. Key variables include nurse and physician leadership, interdependence, psychological safety, coordination, and encounter preparedness. Reliability and validity of survey measures were assessed with exploratory factor analysis and Cronbach alphas. Multivariate analyses tested hypotheses. Professional leadership by nurses and physicians is related to encounter preparedness by different paths. Nurse leadership is associated with greater team interdependence, and interdependence is positively associated with respect. Physician leadership is positively associated with greater psychological safety, respect, and shared goals but is not associated with interdependence. Respect is associated with involvement in learning activities, and shared goals are associated with coordination. Coordination and involvement in learning activities are positively associated with encounter preparedness. By focusing on increasing interdependence and a constructive climate, nurse and physician leaders have the opportunity to increase care coordination

Transformational and transactional leadership skills for mental health teams.
Corrigan, P W; Garman, A N
1999-08-01
Many treatments for persons with severe mental illness are provided by mental health teams. Team members work better when led by effective leaders. Research conducted by organizational psychologists, and validated on mental health teams, have identified a variety of skills that are useful for these leaders. Bass (1990, 1997) identified two sets of especially important skills related to transformational and transactional leadership. Leaders using transformational skills help team members to view their work from more elevated perspectives and develop innovative ways to deal with work-related problems. Skills related to transformational leadership promote inspiration, intellectual stimulation, individual consideration, participative decision making, and elective delegation. Mental health and rehabilitation teams must not only develop creative and innovative programs, they must maintain them over time as a series of leader-team member transactions. Transactional leadership skills include goal-setting, feedback, and reinforcement strategies which help team members maintain effective programs.

Bla g 1 allergen levels in Zagreb area household dust.
Prester, Ljerka; Macan, Jelena
2011-03-01
Cockroach allergy is a health problem in many parts of the world. In urban environments, indoor exposure to cockroach allergens involves a risk of asthma. The aim of this study was to measure the mass fraction of Bla g 1, a major allergen of the German cockroach (Blatella germanica) in 30 house samples, collected at random from Zagreb area households, Croatia. Dust samples were collected on cellulose filters by vacuuming living rooms floors. After extraction, Bla g 1 was detected using the commercial enzyme-linked immunosorbent assay (ELISA). Only four of the thirty households had detectable Bla g 1 levels, and only in one was its concentration higher than 2.0 U g(-1), the threshold associated with sensitisation. The Bla g 1 ELISA proved highly sensitive, with the detection limit of 0.12 U g(-1). The within- and between-assay imprecision was 8.9 % and 14.4 %, respectively, and accuracy 85 % to 120 %. Low Bla g 1 levels in the household dust support previously reported low prevalence of skin sensitisation to B. germanica among Zagreb residents. Further monitoring should reveal if there are differences in cockroach allergen exposure and sensitisation between households from other geographic areas in Croatia.

Transformational leadership and the mental health team.
Corrigan, Patrick W; Diwan, Sarah; Campion, John; Rashid, Fadwa
2002-11-01
Bass's (1990) multifactor model contrasts transformational and transactional styles of leadership with an essentially ineffective style: laissez-faire leadership. This study examines the relationship between these leadership styles and measures of organizational culture and staff burnout in mental health services teams. There were 236 leaders and 620 subordinates from 54 mental health teams who provided their perceptions of leadership style, organizational culture, and burnout in their program. Results show transformational leadership to be positively associated with a cohesive organizational culture and negatively associated with burnout. Moreover, leaders and subordinates differ in their ratings of transformational leadership-leaders viewed themselves more positively. These findings are helpful for understanding the central role of leaders in the organizational structure of teams.

BlaI is a repressor of BlaZ, the beta-lactamase responsible for penicillin resistance in Staphylococcus aureus. Through screening a transposon library in S. aureus Newman for susceptibility to cathelicidin antimicrobial peptide, we discovered BlaI as a novel cathelicidin resistance factor. Additionally, through integrational mutagenesis in S. aureus Newman and MRSA Sanger 252 strains, we confirmed the role of BlaI in resistance to human and murine cathelidicin and showed that it contributes to virulence in human whole blood and murine infection models. We further demonstrated that BlaI could be a target for innate immune-based antimicrobial therapies; by removing BlaI through subinhibitory concentrations of 6-aminopenicillanic acid, we were able to sensitize S. aureus to LL-37 killing.

The systemic surveillance of imipenem-resistant Acinetobacter baumannii (IRAB) from multicenters in Taiwan revealed the emergence of isolates with bla(OXA-72). This study described their genetic makeup, mechanism of spread, and contribution to carbapenem resistance. Two hundred and ninety-one non-repetitive isolates of A. baumannii were collected from 10 teaching hospitals from different geographical regions in Taiwan from June 2007 to September 2007. Minimal inhibitory concentrations (MICs) were determined by agar dilution. Clonality was determined by pulsed-field gel electrophoresis. Plasmid was extracted and digested by restriction enzymes, and subsequently analyzed by electrophoresis and Southern blot for bla(OXA-72). The flanking regions of bla(OXA-72) were determined by inverse PCR. The contribution of bla(OXA-72) to imipenem MIC was determined by transforming plasmids carrying bla(OXA-72) into imipenem-susceptible A. baumannii. Among 142 IRAB in Taiwan, 27 harbored bla(OXA-72); 22 originated from Southern Taiwan, 5 from Central Taiwan, and none from Northern Taiwan. There were two major clones. The bla(OXA-72) was identified in the plasmids of all isolates. Two genetic structures flanking plasmid-borne bla(OXA-72) were identified and shared identical sequences in certain regions; the one described in previous literature was present in only one isolate, and the new one was present in the remaining isolates. Introduction of bla(OXA-72) resulted in an increase of imipenem MIC in the transformants. The overexpression of bla(OXA-72) mRNA in response to imipenem further supported the contribution of bla(OXA-72). In conclusion, isolates with new plasmid-borne blaOXA-72 were found to be disseminated successfully in Southern Taiwan. The spread of the resistance gene depended on clonal spread and dissemination of a new plasmid. Bla(OXA-72) in these isolates directly led to their imipenem-resistance.

The clinical nurse leader: a response from practice.
Drenkard, Karen Neil
2004-01-01
In October 2003, over 200 nurse leaders from education and practice met at the invitation of the American Association of Colleges of Nursing. A newly released white paper, describing the role of the clinical nurse leader, was discussed at the conference. This article outlines a response to that white paper from one practice setting. The article shares information about another role, that of team coordinator, that is similar to clinical nurse leader and has been implemented at an integrated not-for-profit health care system in 5 hospitals. The comparison of the team coordinator role to the clinical nurse leader role might assist in visualizing such a role in practice. Although the roles are not identical, many of the driving forces for change were similar; these included the need to meet the changing demands for improved patient outcomes and nurse retention. The team coordinator role has 4 domains of practice that are crosswalked against the clinical nurse leader 15 core competencies. An evaluation of the team coordinator role showed changes that need to be made, such as placing more emphasis on clinical progression of patients. Lessons learned are shared, including keeping the scope of the role manageable, providing documentation standards for new roles, and the leadership required of the nursing executive to implement change.

2007-03-01
A multilevel model of leadership, empowerment, and performance was tested using a sample of 62 teams, 445 individual members, 62 team leaders, and 31 external managers from 31 stores of a Fortune 500 company. Leader-member exchange and leadership climate related differently to individual and team empowerment and interacted to influence individual empowerment. Also, several relationships were supported in more but not in less interdependent teams. Specifically, leader-member exchange related to individual performance partially through individual empowerment; leadership climate related to team performance partially through team empowerment; team empowerment moderated the relationship between individual empowerment and performance; and individual performance was positively related to team performance. Contributions to team leadership theory, research, and practices are discussed. (c) 2007 APA, all rights reserved.

From a basis in social exchange theory, the authors investigated whether, and how, negative feedback-seeking behavior and a team empowerment climate affect the relationship between leader-member exchange (LMX) and member performance. Results showed that subordinates' negative feedback-seeking behavior mediated the relationship between LMX and both objective and subjective in-role performance. In addition, the level of a team's empowerment climate was positively related to subordinates' own sense of empowerment, which in turn negatively moderated the effects of LMX on negative feedback-seeking behavior. 2007 APA, all rights reserved

We examine how interpersonal behavior and social interaction influence team sensemaking and subsequent team actions during a hospital-based health information technology (HIT) implementation project. Over the course of 18 months, we directly observed the interpersonal interactions of HIT implementation teams using a sensemaking lens. We identified three voice-promoting strategies enacted by team leaders that fostered team member voice and sensemaking; communicating a vision; connecting goals to team member values; and seeking team member input. However, infrequent leader expressions of anger quickly undermined team sensemaking, halting dialog essential to problem solving. By seeking team member opinions, team leaders overcame the negative effects of anger. Leaders must enact voice-promoting behaviors and use them throughout a team's engagement. Further, training teams in how to use conflict to achieve greater innovation may improve sensemaking essential to project risk mitigation. Health care work processes are complex; teams involved in implementing improvements must be prepared to deal with conflicting, contentious issues, which will arise during change. Therefore, team conflict training may be essential to sustaining sensemaking. Future research should seek to identify team interactions that foster sensemaking, especially when topics are difficult or unwelcome, then determine the association between staff sensemaking and the impact on HIT implementation outcomes. We are among the first to focus on project teams tasked with HIT implementation. This research extends our understanding of how leaders' behaviors might facilitate or impeded speaking up among project teams in health care settings.

Becoming a nursing faculty leader.
Young, Patricia K; Pearsall, Catherine; Stiles, Kim A; Horton-Deutsch, Sara
2011-01-01
Academic leaders are one component of a well-prepared faculty that is required to achieve and sustain excellent educational programs. But what is it like to become an academic leader? How does one become a leader? These questions were addressed in an interpretive study in which nurse faculty leaders were interviewed about the experience of becoming a leader. Interview texts were analyzed hermeneutically by a research team to uncover three themes (common, shared experiences): Being Thrust into Leadership, Taking Risks, and Facing Challenges, which are explicated in this article. This study develops the evidence base for leadership preparation at a time when there is a strong need for nursing education leaders in academia.

The authors investigated the relationship between transformational leadership behavior and group performance in 218 financial services teams that were branches of a bank in Hong Kong and the United States. Transformational leadership influenced team performance through the mediating effect of team potency. The effect of transformational leadership on team potency was moderated by team power distance and team collectivism, such that higher power distance teams and more collectivistic teams exhibited stronger positive effects of transformational leadership on team potency. The model was supported by data in both Hong Kong and the United States, which suggests a convergence in how teams function in the East and West and highlights the importance of team values.

Mental health team leadership and consumers satisfaction and quality of life.
Corrigan, P W; Lickey, S E; Campion, J; Rashid, F
2000-06-01
The purpose of this study was to determine the association between leadership styles of leaders of mental health treatment teams and consumers' ratings of satisfaction with the program and their quality of life. A multifactor model has distinguished three factors relevant to leadership of mental health teams: transformational leadership, in which a leader's primary goal is to lead the team to evolving better programs; transactional leadership, in which the leader strives to maintain effective programs through feedback and reinforcement; and laissez-faire leadership, an ineffective, hands-off leadership style. Research has shown transformational leadership to be positively associated with measures of the team's functioning, but the effects of leadership style on consumers is not well known. A total of 143 leaders and 473 subordinates from 31 clinical teams rated the leadership style of the team leader. In addition, 184 consumers served by these teams rated their satisfaction with the treatment program and their quality of life. Consumers' satisfaction and quality of life were inversely associated with laissez-faire approaches to leadership and positively associated with both transformational and transactional leadership. Moreover, leaders' and subordinates' ratings of team leadership accounted for independent variance in satisfaction ratings-up to 40 percent of the total variance. Leadership seems to be an important variable for understanding a team's impact on its consumers.

One of the most important emerging carbapenem-resistant bacteria is Klebsiella pneumoniae (K. pneumoniae). The present study aimed to investigate the antibiotic susceptibility pattern of K. pneumoniae isolates and detection of carbapenemase producing K. pneumoniae obtained from Iranian hospitalized patients. This cross-sectional study was performed on 211 K. pneumoniae isolates which were recovered from different clinical specimens from 2014 to 2015. Modified Hodge test (MHT) and double disk synergy test (DDST) were done for detection of carbapenemase and metallo-beta-lactamase (MBL) producing K. pneumoniae. The presence of antibiotic resistance determinants was investigated by polymerase chain reaction (PCR) method. The results of antibiotic susceptibility showed that all isolates were resistant to ampicillin, and then mostly resistant to piperacillin and ceftazidime with 76.3% and 66.8%, respectively. On the other hand, the highest sensitivity was toward polymyxin B, followed by carbapenems. Of 29 carbapenem-resistant isolates, all were high-level imipenem-resistant isolates (Minimum inhibitory concentration ≥4), except 4 isolates. The results of MHT and DDST showed that 93.1% (27/29) of carbapenem-resistant isolates were carbapenemase and MBL producing isolates, respectively. The presence of bla NDM-1 and bla OXA-48-like genes was detected in 27 (10.9%) and 2 (0.9%) isolates, respectively. This is the first identification of bla NDM-1 and bla OXA-48-like in K. pneumoniae in Southwestern Iran and the highest reported prevalence of bla NDM in this bacterium from Iran. Since carbapenem-resistant isolates containing New Delhi metallo-beta-lactamase 1 (NDM-1) were almost resistant to all the tested antibiotics, the resistance due to this gene may be increased in the near future as a potential health threat.

Several epidemiology studies have found an increase in the major cockroach allergen Bla g 2 with reported pesticide use. Our aim was to investigate the effect on the excretion of Bla g 1 and Bla g 2 allergens by cockroaches exposed to sub-lethal doses of the pesticides, boric acid and hydramethylnon gel. German cockroaches in separate colonies were fed either boric acid or hydramethylnon gel at concentrations of 0.2, 0.1 and 0.01% in their water supply over a 2 week period. Ten colonies were exposed to each treatment concentration. Bla g 1 and Bla g 2 in fecal pellets were measured by ELISA. Cockroaches exposed to boric acid excreted fecal pellets with significantly higher concentrations of Bla g 2 (35,400 U/g) than did controls (12,700 U/g) (P = 0.001). Bla g 1 concentrations were not significantly different. There was no difference in either Bla g 1 or Bla g 2 concentrations between cockroaches that ingested hydramethylnon gel and those in the controls colonies. The application of boric acid, a common pesticide, appears to paradoxically increase the production of Bla g 2, a major allergen, by the surviving cockroaches. This may have important implications in avoidance strategies.

The purpose of this study was to investigate how high-quality dyadic co-worker relationships (CWXs) favour or hinder team performance. Specifically, we examine the role played by CWX, team creative environment, job complexity and task interdependence to achieve higher levels of team performance. We analyse data from 410 individuals belonging to 81 R&D teams in technology sciences to examine the quality of the dyadic relationships between team members under the same supervisor (co-workers) and team performance measured by the number of publications as their research output. Higher levels of team average CWX relationships are positively related to the establishment of a favourable creative team environment, ending into higher levels of team performance. Specifically, the role played by team average CWX in such relationship is stronger when job complexity and task interdependence are also high. Team's output not only depends on the leader and his/her relationships with subordinates but also on quality relationships among team members. CWXs contribute to creative team environments, but they are essential where jobs are complex and tasks are highly dependent. This study provides evidence of the important role played by CWXs in determining a creative environment, irrespective of their leaders. Previous research has provided information about how leader's role affects team outcomes, but the role of dyadic co-worker relationships in a team remains still relatively unknown. Considering job complexity and task interdependence variables, the study provides with a better understanding about how and when high-quality CWXs should be promoted to achieve higher team performance.

Survival of the fittest: implications of self-reliance and coping for leaders and team performance.
Daus, C S; Joplin, J R
1999-01-01
Using a laboratory methodology, the authors sought to establish an association between self-reliance (based on attachment theory) and team performance and satisfaction. Three hypotheses (direct effect, mediator, and moderator) were tested. With a sample of 187 students, the authors compared leader self-reliance characteristics with group member self-reliance characteristics (group n = 50) as predictors of group performance and satisfaction. Only group member counterdependence was predictive of decreased performance. Further, the authors examined the possible mediating and moderating effects of coping on the self-reliance-group effectiveness relationships. Coping did not mediate the relationship but did operate as a significant moderator in some instances.

Empowering and guiding the team has become crucial to the long-term success of any business. Today, an important measurement for leaders is their ability to facilitate a group of people to work together as a team and successfully accomplish their task. What will separate a good leader from a great leader will be the understanding and development of his or her facilitation skills.

Background Sensitization to cockroach allergens is a major risk factor for asthma. The cockroach allergen Bla g 1 has multiple repeats of ~100 amino acids, but the fold of the protein and the biological function are unknown. Objective To determine the structure of Bla g 1, investigate the implications for allergic disease, and standardize cockroach exposure assays. Methods Natural Bla g 1 and recombinant constructs were compared by ELISA using specific murine IgG and human IgE. The structure of Bla g 1 was determined by X-ray crystallography. Mass spectrometry and NMR were utilized to examine ligand-binding properties of the allergen. Results The structure of a recombinant Bla g 1 construct with comparable IgE and IgG reactivity to the natural allergen was solved by X-ray crystallography. The Bla g 1 repeat forms a novel fold with 6 helices. Two repeats encapsulate a large and nearly spherical hydrophobic cavity, defining the basic structural unit. Lipids in the cavity varied depending on the allergen origin. Palmitic, oleic and stearic acids were associated with nBla g 1 from cockroach frass. One Unit of Bla g 1 was equivalent to 104 ng of allergen. Conclusions Bla g 1 has a novel fold with a capacity to bind various lipids, which suggests a digestive function associated with non-specific transport of lipid molecules in cockroaches. Defining the basic structural unit of Bla g 1 facilitates the standardization of assays in absolute units for the assessment of environmental allergen exposure. PMID:23915714

Relatively little empirical research has been conducted on external leaders of self-managing teams. The integration of functional leadership theory with research on team routines suggests that leaders can intervene in teams in several different ways, and the effectiveness of this intervention depends on the nature of the events the team encounters. External team leaders from 3 organizations first described a series of events (N=117), and leaders and team members then completed surveys to quantitatively describe the events. Results indicated that leader preparation and supportive coaching were positively related to team perceptions of leader effectiveness, with preparation becoming more strongly related to effectiveness as event novelty increased. More active leader intervention activities (active coaching and sense making) were negatively related to satisfaction with leadership yet were positively related to effectiveness as events became more disruptive.

The health care industry embraces the concept that collective learning occurs through group social interactions and has been initiating huddles as an avenue for collaborative learning. During change of shift or prior to beginning daily tasks, a huddle is initiated and facilitated by the manager or frontline supervisor. Given that "shared knowledge is obtained through group-based learning," why are some teams learning and others are not? The phenomenon is perplexing, given that the same resources are provided to all teams. Based on the findings in the literature review on learning in groups, teams learn from huddles and others do not because of the following: communication style and dialogue among the group members, communication style and dialogue facilitated by the leader, team and member perceptions, and team membership. Teams that learn from huddles do so because of the elements within the dialogue between team members (reflexive questioning, redundancy of information, metaphors, analogies, dramatic dialogue, strategic meaning) and because the huddle team exhibits higher levels of collegiality, tenure, heterogeneity, team identification, and collective efficacy. Facilitators must encourage a conversation in order to encourage reframing of cognitive maps that encourage learning by huddle members.

This study investigated the characteristics of Escherichia coli isolates carrying mcr-1-bla NDM from a chicken farm in China. Of the 78 E. coli isolates, 21 clonally unrelated isolates carried mcr-1-bla NDM Diverse IncI2 plasmids disseminated mcr-1 , while the dissemination of bla NDM was mediated by diverse IncB/O plasmids. More striking was the colocalization of resistance genes mcr-1 and bla NDM-4 in an IncHI2/ST3 plasmid, which might pose a great challenge for public health.

To investigate the association between the time taken to make a decision to go to surgery and gender, ethnicity, years in profession, experience of trauma team training, experience of structured trauma courses and trauma in the trauma team, as well as use of closed-loop communication and leadership styles during trauma team training. In situ trauma team training. The patient simulator was preprogrammed to represent a severely injured patient (injury severity score: 25) suffering from hypovolemia due to external trauma. An emergency room in an urban Scandinavian level one trauma centre. A total of 96 participants were divided into 16 trauma teams. Each team consisted of six team members: one surgeon/emergency physician (designated team leader), one anaesthesiologist, one registered nurse anaesthetist, one registered nurse from the emergency department, one enrolled nurse from the emergency department and one enrolled nurse from the operating theatre. HRs with CIs (95% CI) for the time taken to make a decision to go to surgery was computed from a Cox proportional hazards model. Three variables remained significant in the final model. Closed-loop communication initiated by the team leader increased the chance of a decision to go to surgery (HR: 3.88; CI 1.02 to 14.69). Only 8 of the 16 teams made the decision to go to surgery within the timeframe of the trauma team training. Conversely, call-outs and closed-loop communication initiated by the team members significantly decreased the chance of a decision to go to surgery, (HR: 0.82; CI 0.71 to 0.96, and HR: 0.23; CI 0.08 to 0.71, respectively). Closed-loop communication initiated by the leader appears to be beneficial for teamwork. In contrast, a high number of call-outs and closed-loop communication initiated by team members might lead to a communication overload. Published by the BMJ Publishing Group Limited.

This study was designed to investigate the prevalence of metallo-β-lactamase (MBL) in Pseudomonas aeruginosa isolates collected from Suez Canal University Hospital in Ismailia, Egypt. Antibiotic susceptibility testing and phenotypic and genotypic screening for MBLs were performed on 147 isolates of P. aeruginosa. MICs were determined by agar dilution method for carbapenem that was ≥2 μg/mL for meropenem. MBL genes were detected by multiplex and monoplex PCR for P. aeruginosa-harbored plasmids. Mutation profile of sequenced MBL genes was screened using online software Clustal Omega. Out of 147 P. aeruginosa, 39 (26.5%) were carbapenem-resistant isolates and 25 (64%) were confirmed to be positive for MBLs. The susceptibility rate of P. aeruginosa toward polymyxin B and norfloxacin was 99% and 88%, respectively. Identification of collected isolates by API analysis and constructed phylogenetic tree of 16S rRNA showed that the isolates were related to P. aeruginosa species. The frequency of blaGIM-1, blaSIM-1, and blaSPM-1 was 52%, 48%, and 24%, respectively. BlaVIM and blaIMP-like genes were 20% and 4% and the sequences confirm the isolate to be blaVIM-1, blaVIM-2, blaVIM-4, and blaIMP-1. Three mutations were identified in blaVIM-4 gene. Our study emphasizes the high occurrence of multidrug-resistant P. aeruginosa-producing MBL enzymes. © 2017 APMIS. Published by John Wiley & Sons Ltd.

Making star teams out of star players.
Mankins, Michael; Bird, Alan; Root, James
2013-01-01
Top talent is an invaluable asset: In highly specialized or creative work, for instance, "A" players are likely to be six times as productive as "B" players. So when your company has a crucial strategic project, why not multiply all that firepower and have a team of your best performers tackle it? Yet many companies hesitate to do this, believing that all-star teams don't work: Big egos will get in the way. The stars won't be able to work with one another. They'll drive the team Leader crazy. Mankins, Bird, and Root of Bain & Company believe it's time to set aside that thinking. They have seen all-star teams do extraordinary work. But there is a right way and a wrong way to organize them. Before you can even begin to assemble such a team, you need to have the right talent management practices, so you hire and develop the best people and know what they're capable of. You have to give the team appropriate incentives and leaders and support staffers who are stars in their own right. And projects that are ill-defined or small scale are not for all-star teams. Use them only for critical missions, and make sure their objectives are clear. Even with the right setup, things can still go wrong. The wise executive will take steps to manage egos, prune non-team-players, and prevent average coworkers from feeling completely undervalued. She will also invest a lot of time in choosing the right team Leader and will ask members for lots of feedback to monitor how that leader is doing.

Leadership within nursing is receiving unprecedented focus and development. This reflective narrative explores the nature of leadership, termed scholarly leadership, by an academic and a clinical leader of a Nursing Development Unit. The narrative explores the characteristics of such leadership and highlights how it empowered a nursing team to further reach its potential. Two areas, patient-centered care and the characteristics of practice, are focused upon to highlight the leadership style that the clinical leader adopted. The paper concludes by suggesting what structural and systems changes need to be put in place in order to bring about change.

Combinations of β-lactams with clavulanate are currently being investigated for tuberculosis treatment. Since Mycobacterium tuberculosis produces a broad spectrum β-lactamase, BlaC, the success of this approach could be compromised by the emergence of clavulanate-resistant variants, as observed for inhibitor-resistant TEM variants in enterobacteria. Previous analyses based on site-directed mutagenesis of BlaC have led to the conclusion that this risk was limited. Here, we used a different approach based on determination of the crystal structure of β-lactamase BlaMAb of Mycobacterium abscessus, which efficiently hydrolyzes clavulanate. Comparison of BlaMAb and BlaC allowed for structure-assisted site-directed mutagenesis of BlaC and identification of the G132N substitution that was sufficient to switch the interaction of BlaC with clavulanate from irreversible inactivation to efficient hydrolysis. The substitution, which restored the canonical SDN motif (SDG→SDN), allowed for efficient hydrolysis of clavulanate, with a more than 104-fold increase in kcat (0.41 s−1), without affecting the hydrolysis of other β-lactams. Mass spectrometry revealed that acylation of BlaC and of its G132N variant by clavulanate follows similar paths, involving sequential formation of two acylenzymes. Decarboxylation of the first acylenzyme results in a stable secondary acylenzyme in BlaC, whereas hydrolysis occurs in the G132N variant. The SDN/SDG polymorphism defines two mycobacterial lineages comprising rapidly and slowly growing species, respectively. Together, these results suggest that the efficacy of β-lactam–clavulanate combinations may be limited by the emergence of resistance. β-Lactams active without clavulanate, such as faropenem, should be prioritized for the development of new therapies.

Recent literature has been critical of research that adopts a narrow focus on single leaders and on leadership attributes and has called for attention to leadership that is distributed among individuals and to practices in which leaders engage. We conducted a study of health care teams where we attended to role distribution among leadership constellation members and to loose or tight coupling practices between leaders and the remainder of the team. This focus provides insights into how leadership can be practiced and structured to enhance team functioning. A qualitative, multicase study of four teams was conducted. Data collection involved 44 interviews with almost all the members of the teams and 18 team meeting observations. Thematic analysis was conducted by the two authors. Leadership constellations can give rise to leadership role overlaps and gaps that may create ambiguity within teams, ambiguity is diminished if the leaders can agree on which leader assumes ultimate authority in an area, the presence of more leaders does not necessarily entail more comprehensive fulfillment of team needs, and teams' needs for tight or loose leadership practices are influenced by contextual factors that we elaborate. (a) It is important to recognize areas of overlap and gaps in leadership roles and to provide clarity about role boundaries to avoid ambiguity. Role mapping exercises and open discussions should be considered. (b) Attempting to spread formal leadership responsibilities informally among individuals is not always a workable strategy for addressing team needs. (c) Organizations need to examine critically the allocation of resources to leadership activities.

Building a leadership team that works.
Blomenberg, Emily M
2005-01-01
Radiology administrators often are challenged to do more with less. In today's fast-paced work environment, leaders must be creative. They must surround themselves with good people in order to successfully achieve their organizations' goals. Once a radiology administrator is satisfied and comfortable that he or she has, the right staff involved, a leadership team can be formally establislished. Howard Regional Health System established an Imaging Services Leadership Team with a vision to provide leaders for the staff to "follow," just as team members learn from the radiology administrator. In addition, team members are vital in assisting the radiology administrator in managing the department The process of building the team consisted of 3 steps: selecting team members (the most challenging and time-consuming component), formalizing a functional team, and putting the team into action. Finding the right people, holding regular meetings, and making those team meetings meaningful are keys to a successful leadership team. The implementation of the team has had a positive effect on imaging services: the number of procedures has increased, the team is used as a communication tool for front-line staff, front-line staff are becoming more comfortable with making decisions.

Antibiotic sensitivity pattern in blaNDM-1-positive and carbapenemase-producing Enterobacteriaceae
Mulla, Summaiya; Charan, Jaykaran; Rajdev, Sangita
2016-01-01
Background: Some studies published in recent time revealed that many bacteria from Enterobacteriaceae group are multi-antibiotic-resistant because of the production enzymes carbapenemase particularly New Delhi metallo-beta-lactamase encoded by gene called blaNDM-1. Looking at public health importance of this issue there is a need for studies at other centers to confirm or refute published findings. Objectives: This study was designed with the aim of exploring antibiotic resistance in Enterobacteriaceae group of bacteria and also to explore gene and enzyme responsible for it. Materials and Methods: Samples of Enterobacteriaceae were collected from wards and outpatient departments. Antibiotic sensitivity was checked by an automated system (VITEK 2 COMPACT). Carbapenemase production was assessed by Modified Hodge Test. Presence of blaNDM-1 was assessed by polymerase chain reaction. Statistics: Frequency and percentage were used to describe the data. Frequency of sensitivity was compared between carbapenemase producers and noncarbapenemase producers by Fisher's exact test. Results: Forty-seven percent bacteria were found to be producing carbapenemase enzyme. These bacteria were significantly less sensitive to cefoperazone, cefepime, and amikacin. Among carbapenemase-producing organisms, 3% and 6% were resistant to tigecycline and colistin, respectively. Forty percent bacteria were found to be having blaNDM-1 gene. There was a significant difference between blaNDM-1-positive and blaNDM-1-negative for sensitivity toward cefoperazone + sulbactam, imipenem, meropenem, amikacin, tobramycine, ciprofloxacin, and levofloxacin. Conclusion: Presence of carbapenemase enzyme and blaNDM-1 gene is associated with high level of resistance in Enterobacteriaceae group of bacteria and only few antibiotics have good sensitivity for these organisms.

The emergence of carbapenem-resistant Acinetobacter baumannii has been observed worldwide. We describe the first detection of A. baumannii carrying the blaNDM-1 gene in Lebanon, isolated from Syrian patients wounded during the civil war. Four carbapenem-resistant A. baumannii strains isolated in 2012 in the Tripoli Government Hospital, Lebanon, from civilians wounded during the Syrian war, were analysed. Susceptibility was determined by disk diffusion testing, and resistance to carbapenems was confirmed by Etest. The presence of blaOXA-23-like, blaOXA-24-like, blaOXA-58-like, blaOXA-143-like, and blaNDM was investigated by PCR. Clonal relationships were studied by pulsed-field gel electrophoresis (PFGE), multilocus sequence typing (MLST), and blaOXA-51 sequence-based typing. All isolates harboured the blaNDM-1 gene and were negative for other tested carbapenemases. They all belonged to the sequence type 85 and formed a single cluster by PFGE. Finally, blaOXA-51-like gene sequencing revealed the presence of the blaOXA-94 variant in all four isolates. These findings show that Syria constitutes a reservoir for NDM-1-producing bacteria. These results also highlight the need for effective measures to stop the threatening spread of such strains. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

The bla OXA-23 group was considered as the first group of OXA-type β-lactamases conferring carbapenem resistance and has been reported worldwide in Acinetobacter baumannii, however their presence in Escherichia coli is very rare and unique. This study describes an unusual occurrence of bla OXA-23 in 14 clinical isolates of E. coli obtained from intensive care unit patients admitted to a tertiary referral hospital in India. The bla OXA-23 gene was found located within a self-conjugative plasmid of IncF rep B and IncK incompatibility types and simultaneously carrying bla CTX-M-15 , bla VEB-1 , bla PER-1 and/or bla NDM-1 . The copy number of bla OXA-23 within the IncK-type plasmid was inversely proportional to increasing concentrations of imipenem, whereas in the case of the IncF rep B-type the result was variable; and increased copy number of the IncK-type plasmid was observed with increasing concentrations of meropenem. Plasmids encoding bla OXA-23 could be successfully eliminated after single treatment and were found to be not highly stable, as complete loss of plasmids was observed within 5-10 days. This study emphasises that carbapenem stress invariably altered the copy number of two different Inc type plasmids encoding the bla OXA-23 resistance gene and also highlights a potential threat of clonal expansion of this class D carbapenemase through a heterologous host in this country, which is in second incidence globally.

Salmonella is an important cause of foodborne illness; however, identifying the source of these infections can be difficult. This is especially true for Salmonella serotype Typhimurium, which is found in diverse agricultural niches. Extended-spectrum cephalosporins (ESC) are one of the primary treatment choices for complicated Salmonella infections. In Salmonella, ESC resistance in the United States is mainly mediated by blaCMY genes carried on various plasmids. In this study, we examined whether the characterization of blaCMY plasmids, along with additional information, can help us identify potential sources of infection by Salmonella, and used serotype Typhimurium as a model. In the United States, monitoring of retail meat, food animals, and ill persons for antimicrobial-resistant Salmonella is conducted by the National Antimicrobial Resistance Monitoring System. In 2008, 70 isolates (70/581; 12.0%) (34 isolates from retail meat, 23 food animal, and 13 human) were resistant to ceftriaxone and amoxicillin/clavulanic acid. All were polymerase chain reaction (PCR)-positive for blaCMY and 59/70 (84.3%) of these genes were plasmid encoded. PCR-based replicon typing identified 42/59 (71.2%) IncI1-blaCMY plasmids and 17/59 (28.8%) IncA/C-blaCMY plasmids. Isolates from chickens or chicken products with blaCMY plasmids primarily had IncI1-blaCMY plasmids (37/40; 92.5%), while all isolates from cattle had IncA/C-blaCMY plasmids. Isolates from humans had either IncA/C- blaCMY (n=8/12; [66.7%]) or IncI1- blaCMY (n=4/12 [33.3%]) plasmids. All of the IncI1-blaCMY plasmids were ST12 or were closely related to ST12. Antimicrobial susceptibility patterns (AST) and pulsed-field gel electrophoresis (PFGE) patterns of the isolates were also compared and differences were identified between isolate sources. When the source of a Typhimurium outbreak or sporadic illness is unknown, characterizing the outbreak isolate's blaCMY plasmids, AST, and PFGE patterns may help identify it.

The spread of carbapenem-resistant Klebsiella pneumoniae especially bla NDM-1 -carrying isolates is a great concern worldwide. In this study we describe the molecular basis of carbapenem-resistant K. pneumoniae in three teaching hospitals at Bandar Abbas, south of Iran. A total of 170 nonduplicate clinical isolates of K. pneumoniae were investigated. Antimicrobial susceptibility test was performed by disc diffusion method. PCR was carried out for detection of carbapenemase (bla KPC , bla IMP , bla VIM , bla NDM , bla SPM , bla OXA-48 , and bla OXA-181 ) and extended-spectrum β-lactamase (bla CTX-M , bla SHV , bla TEM , bla VEB , bla GES , and bla PER ). Clonal relatedness of bla NDM-1 -positive isolates was evaluated by multilocus sequence typing (MLST). Tigecycline was the most effective antimicrobial agent with 96.5% susceptibility. In addition, 6.5% of the isolates were carbapenem resistant. Bla NDM-1 was identified in four isolates (isolate A-D) and all of them were multidrug-resistant. MLST revealed that bla NDM-1 -positive isolates were clonally related and belonged to two distinct clonal complexes, including sequence type (ST) 13 and ST 392. In addition to bla NDM-1, isolate A coharbored bla SHV-11 , bla CTX-M-15 , and bla TEM-1 , isolate B harbored bla SHV-11 and bla CTX-M-15 , and isolates C and D contained both bla SHV-1 and bla CTX-M-15 . Our results indicate that NDM-1-producing K. pneumoniae ST 13 and ST 392 are disseminated in our region. Moreover, one of our major concerns is that these isolates may be more prevalent in the near future. Tracking and urgent intervention is necessary for control and prevention of these resistant isolates.

Antibiotic resistance (AR) is often rooted in inappropriate antibiotic use, but poor water quality and inadequate sanitation exacerbate the problem, especially in emerging countries. An example is increasing multi-AR due to mobile carbapenemases, such as NDM-1 protein (coded by blaNDM-1 genes), which can produce extreme drug-resistant phenotypes. In 2010, NDM-1 positive isolates and blaNDM-1 genes were detected in surface waters across Delhi and have since been detected across the urban world. However, little is known about blaNDM-1 levels in more pristine locations, such as the headwaters of the Upper Ganges River. This area is of particular interest because it receives massive numbers of visitors during seasonal pilgrimages in May/June, including visitors from urban India. Here we quantified blaNDM-1 abundances, other AR genes (ARG), and coliform bacteria in sediments and water column samples from seven sites in the Rishikesh-Haridwar region of the Upper Ganges and five sites on the Yamuna River in Delhi to contrast blaNDM-1 levels and water quality conditions between season and region. Water quality in the Yamuna was very poor (e.g., anoxia at all sites), and blaNDM-1 abundances were high across sites in water (5.4 ± 0.4 log(blaNDM-1·mL–1); 95% confidence interval) and sediment (6.3 ± 0.7 log(blaNDM-1·mg–1)) samples from both seasons. In contrast, water column blaNDM-1 abundances were very low across all sites in the Upper Ganges in February (2.1 ± 0.6 log(blaNDM-1·mL–1)), and water quality was good (e.g., near saturation oxygen). However, per capita blaNDM-1 levels were 20 times greater in June in the Ganges water column relative to February, and blaNDM-1 levels significantly correlated with fecal coliform levels (r = 0.61; p = 0.007). Given that waste management infrastructure is limited in Rishikesh-Haridwar, data imply blaNDM-1 levels are higher in visitor’s wastes than local residents, which results in seasonally higher blaNDM-1 levels in the

Building effective critical care teams
2011-01-01
Critical care is formulated and delivered by a team. Accordingly, behavioral scientific principles relevant to teams, namely psychological safety, transactive memory and leadership, apply to critical care teams. Two experts in behavioral sciences review the impact of psychological safety, transactive memory and leadership on medical team outcomes. A clinician then applies those principles to two routine critical care paradigms: daily rounds and resuscitations. Since critical care is a team endeavor, methods to maximize teamwork should be learned and mastered by critical care team members, and especially leaders. PMID:21884639

The increase in bla NDM -1 in Enterobacteriaceae has become a major concern worldwide. In previous study, we investigated clonal dissemination and mechanisms of resistance to carbapenem in China. We carried out retrospective surveillance for bla NDM -1 among carbapenem-resistant enterobacter strains, which were isolated from patients at our hospital by bacterial strains selection, antimicrobial susceptibility testing, species identification, and molecular detection of resistance gene. We found three bla NDM -1 -positive isolates which were identified as Enterobacter aerogenes in clinical patients in China. The bla NDM -1 -positive Enterobacter aerogenes isolates were first found. It is important to mandate prudent usage of antibiotics and implement infection control measures to control the spread of these resistant bla NDM -1 -positive strains. © 2016 Wiley Periodicals, Inc.

Multidisciplinary teams (MDTs) are used in healthcare organizations to address both clinical and managerial functions. Despite their prevalence, little is known about how team processes work to facilitate effectiveness among MDT leadership teams. This study explores perceptions of MDT participation experienced by organizational leaders in healthcare organizations in the United States. A survey of American College of Healthcare Executives members was conducted to assess involvement and perceptions of MDTs among health care management professionals. Descriptive statistics, independent T-Tests and Chi-square analyses were used to examine participation in MDTs, perception of MDT processes, and the association of participation and perceived processes with employee and organizational characteristics. The survey yielded a sample comprised of 492 healthcare executive or executive-track employees. An overwhelming majority indicated participation in MDTs. The study identified team processes that could use improvement including communication, cooperation, and conflict resolution. The study provides evidence that can help guide the development of training programs that focus on providing managerial leaders with strategies aimed at improving communication, coordination, and conflict resolution that will improve the effectiveness of MDT functioning in healthcare organizations.

Collaboration and Team Science: From Theory to Practice
Gadlin, Howard
2013-01-01
Interdisciplinary efforts are becoming more critical for scientific discovery and translational research efforts. Highly integrated and interactive research teams share a number of features that contribute to their success in developing and sustaining their efforts over time. Through analysis of in-depth interviews with members of highly successful research teams and others that did not meet their goals or ended due to conflicts, we identified key elements that appear critical for team success and effectiveness. There is no debate that the scientific goal sits at the center of the collaborative effort. However, supporting features need to be in place to avoid the derailment of the team. Among the most important of these is trust: without trust the team dynamic runs the risk of deteriorating over time. Other critical factors of which both leaders and participants need to be aware include developing a shared vision, strategically identifying team members and purposefully building the team, promoting disagreement while containing conflict, and setting clear expectations for sharing credit and authorship. Self-awareness and strong communication skills contribute greatly to effective leadership and management strategies of scientific teams. While all successful teams share the characteristic of effectively carrying out these activities, there is no single formula for execution with every leader exemplifying different strengths and weaknesses. Successful scientific collaborations have strong leaders who are self -aware and are mindful of the many elements critical for supporting the science at the center of the effort. PMID:22525233

Why teams don't work. Interview by Diane Coutu.
Hackman, J Richard
2009-05-01
The belief that teams make us more creative and productive--and are the best way to get things done--is deeply entrenched. But Hackman, a professor of organizational psychology at Harvard and a leading expert on teams, is having none of it. Research, he says, consistently shows that teams underperform despite all their extra resources. In an interview with senior editor Diane Coutu, Hackman explains where teams go wrong. Shockingly, most of the time members don't agree on what the team is supposed to be doing or even on who is on the team. The belief that bigger is better also compounds problems; as a team grows, the effort needed to manage links between members increases almost exponentially. Leaders need to be ruthless about defining teams and keeping them small (fewer than 10 members), and some individuals (like team destroyers) should simply be forced off. The leader also must set a compelling direction for the team--but in so doing, may encounter intense resistance that puts him or her at great risk. Hackman explores other fallacies about teams--for instance, that teams whose members have been together a long time become stale. In fact, research reveals that new teams make 50% more mistakes than established teams. To avoid complacency, though, every team needs a deviant--someone who is willing to make waves and open up the group to more ideas. Unfortunately, such individuals often get thrown off the team, robbing it of its chance to be magical. Leaders can't make a team do well. However, by being disciplined about how a team is set up and managed, instituting the right support systems, and providing coaching in group processes, they can increase the likelihood that a team will be great.

Lift outs: how to acquire a high-functioning team.
Groysberg, Boris; Abrahams, Robin
2006-12-01
More and more, expanding companies are hiring high-functioning groups of people who have been working together effectively within one company and can rapidly come up to speed in a new environment. These lifted-out teams don't need to get acquainted with one another or to establish shared values, mutual accountability, or group norms; their long-standing relationships and trust help them make an impact very quickly. Of course, the process is not without risks: A failed lift out can lead to loss of money, opportunity, credibility, and even native talent. Boris Groysberg and Robin Abrahams studied more than 40 high-profile moves and interviewed team leaders in multiple industries and countries to examine the risks and opportunities that lift outs present. They concluded that, regardless of industry, nationality, or size of the team, a successful lift out unfolds over four consecutive, interdependent stages that must be meticulously managed. In the courtship stage, the hiring company and the leader of the targeted team determine whether the proposed move is, in fact, a good idea, and then define their business goals and discuss strategies. At the same time, the team leader discusses the potential move with the other members of his or her group to assess their level of interest and prepare them for the change. The second stage involves the integration of the team leader with the new company's top leadership. This part of the process ensures the team's access to senior executives-the most important factor in a lift out's success. Operational integration is the focus of the third stage. Ideally, teams will start out working with the same or similar clients, vendors, and industry standards. The fourth stage entails full cultural integration. To succeed, the lifted-out team members must be willing to re-earn credibility by proving their value and winning their new colleagues' trust.

Penicillinase-producing Neisseria gonorroheae (PPNG) was first isolated in 1976. PPNG strains carrying bla TEM-1 and bla TEM-135 gene have been described in different countries. Recently, a novel bla TEM-220 allele was detected in PPNG isolates carrying Toronto/Rio plasmid. The prevalence and characteristics of TEM-220 strains worldwide are unknown, and therefore, it needs to be studied. The purpose of this study was to detect bla TEM-220 gene in PPNG strains possessing Toronto/Rio plasmid over a period of ten years in Argentina, and to evaluate the proportion of isolates producing non-TEM-220 containing the T539C substitution in the bla TEM allele. One hundred and fifty one PPNG isolates carrying Toronto/Rio plasmid were studied between 2002 and 2011. A mismatch amplification mutation assay (MAMA) PCR was used to identify the T539C substitution in the bla TEM allele and a MAMA-PCR protocol was developed to detect the G547A substitution in the bla TEM-220. The reference agar dilution method of the Clinical and Laboratory Standard Institute (CLSI) was used for susceptibility testing to five β-lactams antibiotics, ciprofloxacin, tetracycline and azithromycin. In all TEM-220-producing isolates, the whole bla TEM gene was sequenced and the isolates were typed using N. gonorroheae multiantigen sequence typing (NG-MAST). MAMA PCR successfully identified the G547A substitution in the bla TEM-220 allele. The proportion of isolates that possessed the bla TEM-220 allele was 2.6 %, and 93.2 % MAMA TEM-220 PCR-negative isolates showed the T539C substitution in the bla TEM gene. No differences in the susceptibility to five beta-lactam antibiotics tested were observed in PPNG isolates TEM-220-producing and PPNG isolates carrying the T539C substitution in the bla TEM gene. All TEM-220 isolates were indistinguishable by NG-MAST. This is the first study which shows the prevalence of bla TEM-220 in N. gonorrhoeae isolates carrying Toronto/Rio plasmid in Argentina.

The present research expands upon previous theory and empirical work concerning the leadership-health link by examining the lagged effects of leader identity entrepreneurship (i.e., leaders' creation of a sense of "we" and "us" among team members) on team members' burnout, work engagement and turnover intentions. We report results from a 2-wave field study with employees from a large solar panel producing organization in China conducted over a 10-month period. Findings indicate that perceived leader identity entrepreneurship predicted greater subsequent work engagement among team members, as well as lower subsequent burnout and turnover intentions. Moreover, effects on reduced turnover intentions were mediated by reduced burnout and increased work engagement. These findings are the first to examine how leader identity entrepreneurship impacts subsequent employee health and turnover intentions and suggest that leaders help to promote health and well-being in the workplace by creating and developing a sense of shared identity among those they lead.

Enterobacteriaceae with blaNDM-7 are relatively uncommon and had previously been described in Europe, India, the United States, and Japan. This study describes the characteristics of Enterobacteriaceae (Klebsiella pneumoniae [n = 2], Escherichia coli [n = 2], Serratia marcescens [n = 1], and Enterobacter hormaechei [n = 1] isolates) with blaNDM-7 obtained from 4 patients from Calgary, Canada, from 2013 to 2014. The 46,161-bp IncX3 plasmids with blaNDM-7 are highly similar to other blaNDM-harboring IncX3 plasmids and, interestingly, showed identical structures within the different isolates. This finding may indicate horizontal transmission within our health region, or it may indicate contact with individuals from areas of endemicity within the hospital setting. Patients infected or colonized with bacteria containing blaNDM-7 IncX3 plasmids generate infection control challenges. Epidemiological and molecular studies are required to better understand the dynamics of transmission, the risk factors, and the reservoirs for bacteria harboring blaNDM-7. To the best of our knowledge, this is the first report of S. marcescens and E. hormaechei with blaNDM-7. Copyright © 2016, American Society for Microbiology. All Rights Reserved.

Researchers have argued that leadership is one of the most important determinants of team effectiveness. The present study examined the extent to which the perceived quality of athlete leadership was related to the effectiveness of elite sports teams. Three professional football teams (N=135) participated in our study during the preparation phase for the Australian 2016 season. Players and coaching staff were asked to assess players' leadership quality in four leadership roles (as task, motivational, social, and external leader) via an online survey. The leadership quality in each of these roles was then calculated in a social network analysis by averaging the indegree centralities of the three best leaders in that particular role. Participants also rated their team's performance and its functioning on multiple indicators. As hypothesized, the team with the highest-quality athlete leadership on each of the four leadership roles excelled in all indicators of team effectiveness. More specifically, athletes in this team had a stronger shared sense of the team's purpose, they were more highly committed to realizing the team's goals, and they had a greater confidence in their team's abilities than athletes in the other teams. Moreover, this team demonstrated a higher task-involving and a lower ego-involving climate, and excelled on all measures of performance. High-quality athlete leadership is positively related to team effectiveness. Given the importance of high-quality athlete leadership, the study highlights the need for well-designed empirically-based leadership development programs. Copyright © 2017 Sports Medicine Australia.

The effectiveness of carbapenems, considered as last-resort antimicrobials in severe infections, becomes compromised by bacterial resistance. The production of metallo-β-lactamases (MBLs) is the most significant threat to carbapenems activity among Pseudomonas aeruginosa. The aim of this study was to assess the presence and type of MBLs genes in carbapenem-resistant P. aeruginosa clinical strains, to identify the location of MBLs genes and to determine genetic relatedness between MBL-producers using pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). The first identified MBL-positive (with blaVIM genes) P. aeruginosa strains were isolated from patients hospitalized in the University Clinical Hospital of Bialystok in the period from September 2012 to December 2013. Variants of MBLs genes and variable integron regions were characterized by PCR and sequencing. PFGE was performed after digesting of bacterial genomes by XbaI enzyme. By MLST seven housekeeping genes were analyzed for the determination of sequence type (ST). Three strains carried the blaVIM-2 gene and one harbored the blaVIM-4 gene. The blaVIM genes resided within class 1 integrons. PCR mapping of integrons revealed the presence of four different cassette arrays. Genetic relatedness analysis by PFGE classified VIM-positive strains into four unrelated pulsotypes (A-D). MLST demonstrated the presence of four (ST 111, ST27, and ST17) different sequence type including one previously undescribed new type of ST 2342. Antimicrobial susceptibility testing showed that VIM-positive strains were resistant to carbapenems, cephalosporins, aminoglycosides, and quinolones, intermediate to aztreonam, and susceptible only to colistin. Integrons mapping, PFGE, and MLST results may point to different origin of these strains and independent introduction into hospitalized patients.

Team-Based Multidisciplinary Research Scholarship in the Geosciences

Wernette, P. A.; Houser, C.; Quick, C.
2016-12-01
The traditional approach to undergraduate research can be time-intensive for both the mentee and mentor, and can deter potential undergraduates and faculty from participating in research. The Aggie Research Leadership (ARL) and Aggie Research Scholars (ARS) programs represent a team-based, vertically-tiered, and multidisciplinary approach to research that can successfully address complex and relevant research questions. The program is structured such that faculty mentor one or more graduate students or postdocs, who, in turn, mentor teams of 2 to 8 undergraduate students. While it is the responsibility of the graduate student or postdoc to put together a team that works for their research question, undergraduate teams are encouraged to be multidisciplinary in order to leverage the experience and perspective that comes from students in different areas of study. Team leaders are encouraged to discuss their research teams with the faculty mentor regularly to address any potential issues that they might be having, but team leaders are required to meet regularly with other team leaders to discuss any issues that they might be having. Meeting with new and experienced team leaders is a valuable approach to a graduate student or postdoc developing their own set of best practices for mentoring. This experience is invaluable in their future careers, regardless of the field of study. By collaborating with students from other fields of study, no one student is required to become an expert in all topics relating to the research. Another significant advantage of the ARL/ARS programs is that complex research questions are able to be examined because teams typically continue longer than a single semester or academic year. Research teams are vertically-tiered and typically include freshman through seniors. In this way, younger students on the projects are mentored by senior students when they first arrive. Eventually, the younger students will advance through to senior students and

Objective: To elucidate whether the genetic platforms of blaCTX-M contribute to the phenotypes of multi-drug-resistance (MDR) in the first carbapenemase-producing K. pneumoniae strains isolated in Chile. Method: Twenty-two carbapenemase-producing K. pneumoniae strains isolated from different Chilean patients and hospitals were studied. Their genetic relatedness was assessed by PFGE and MLST. The levels of antibiotic resistance were evaluated by determining the minimum inhibitory concentration of various antimicrobials. In addition, several antibiotic resistance genes of clinical relevance in Chile were investigated. The prevalence, allelic variants, and genetic platforms of blaCTX-M were determined by PCR and sequencing. Results: Out of the 22 strains studied, 20 carry KPC, one carries NDM-1, and one carries OXA-370. The PFGE analysis showed three clades with a genetic relatedness >85%, two formed by four strains and one by eight strains. The other strains are not genetically related, and a total of 17 different pulse types were detected. Ten different STs were identified, the main ones being ST258 (five strains) and ST1161 (seven strains). The isolates presented different percentages of resistance, and 82% were resistant to all the β-lactams tested, 91% to ciprofloxacin, 73% to colistin, 59% to gentamicin, 50% to amikacin, and only 9% to tigecycline. All isolates carried blaTEM and blaSHV, whereas 71% carried aac(6′)Ib-cr, and 57% one qnr gene (A, B, C, D, or S). The blaCTX-M gene was found in 10 of the isolates (4 blaCTX-M−15 and 6 blaCTX-M−2). The characterization of the platform, in seven selected strains, revealed that the gene is associated with unusual class 1 integrons and insertion sequences such as ISCR1, ISECp1, and IS26. Conclusion: In the first carbapenemase-producing K. pneumoniae strains isolated in Chile the genetic platform of blaCTX-M−2 corresponds to an unusual class 1 integron that can be responsible for the MDR phenotype, whereas the

Teamwork in perioperative nursing. Understanding team development, effectiveness, evaluation.
Farley, M J
1991-03-01
Teams are an essential part of perioperative nursing practice. Nurses who have a knowledge of teamwork and experience in working on teams have a greater understanding of the processes and problems involved as teams develop from new, immature teams to those that are mature and effective. This understanding will assist nurses in helping their teams achieve a higher level of productivity, and members will be more satisfied with team efforts. Team development progresses through several stages. Each stage has certain characteristics and desired outcomes. At each stage, team members and leaders have certain responsibilities. Team growth does not take place automatically and inevitably, but as a consequence of conscious and unconscious efforts of its leader and members to solve problems and satisfy needs. Building and maintaining a team is certainly work, but work that brings a great deal of satisfaction and feelings of pride in accomplishment. According to I Tenzer, RN, MS, teamwork "is not a panacea; it is a viable approach to developing a hospital's most valuable resource--people."

To determine the impact of simulation-based instruction on student performance in the role of emergency department resuscitation team leader. A randomized, single-blinded, controlled study using an intention to treat analysis. Eighty-three fourth-year medical students enrolled in an emergency medicine clerkship were randomly allocated to two groups differing only by instructional format. Each student individually completed an initial simulation case, followed by a standardized curriculum of eight cases in either group simulation or case-based group discussion format before a second individual simulation case. A remote coinvestigator measured eight objective performance end points using digital recordings of all individual simulation cases. McNemar chi2, Pearson correlation, repeated measures multivariate analysis of variance, and follow-up analysis of variance were used for statistical evaluation. Sixty-eight students (82%) completed both initial and follow-up individual simulations. Eight students were lost from the simulation group and seven from the discussion group. The mean postintervention case performance was significantly better for the students allocated to simulation instruction compared with the group discussion students for four outcomes including a decrease in mean time to (1) order an intravenous line; (2) initiate cardiac monitoring; (3) order initial laboratory tests; and (4) initiate blood pressure monitoring. Paired comparisons of each student's initial and follow-up simulations demonstrated significant improvement in the same four areas, in mean time to order an abdominal radiograph and in obtaining an allergy history. A single simulation-based teaching session significantly improved student performance as a team leader. Additional simulation sessions provided further improvement compared with instruction provided in case-based group discussion format.

In its recent history, the U.S. Forest Service is among many federal land management agencies struggling with questions concerning why its planning procedures are sometimes inefficient, perform poorly in the eyes of the public, and fail to deliver outputs that advance agency mission. By examining a representative sample of National Environmental Policy Act (NEPA) processes conducted by the agency between 2007 and 2009, we provide new insights into what drives outcomes in these planning processes. We examined team leaders' perceptions of the following outcomes: achievement of agency goals and NEPA mandates, process efficiency, public relations, and team outcomes. The most consistently important predictors of positive outcomes were team harmony and a clearly empowered team leader. Other factors, such as perceptions of the use of best science, a clear and unambiguous purpose and need, team turnover (personnel changes during the process), extra-agency engagement, and intra-agency relations, were also important, but played a less consistent role. The findings suggest the importance of empowering team leaders and team members through enhancing elements of discretion, responsibility, clear role definition, collaborative interdisciplinary deliberation, and perceived self-efficacy. The results also suggest the importance of genuine concern and respect for participating publics and effective inter-agency coordination. Copyright © 2012 Elsevier Ltd. All rights reserved.

Enterobacter aerogenes has recently emerged as an important hospital pathogen. In this study, we showed the emergence of E. aerogenes isolates carrying the blaKPC gene in patients colonized by carbapenem-resistant Klebsiella pneumoniae strains. Two multiresistant E. aerogenes isolates were recovered from bronchial aspirates of two patients hospitalized in the Intensive Care Unit at the "Santa Maria della Scaletta" Hospital, Imola. The antimicrobial susceptibility test showed the high resistance to carbapenems and double-disk synergy test confirmed the phenotype of KPC and AmpC production. Other investigation revealed that ESBL and blaKPC genes were carried on the conjugative pKpQIL plasmid. This is a relevant report in Italy that describes a nosocomial infection due to the production of KPC beta-lactamases by an E. aerogenes isolate in patients previously colonized by K. pneumoniae carbapenem-resistant. In conclusion, it's necessary a continuous monitoring of multidrug-resistant strains for the detection of any KPC-producing bacteria that could expand the circulation of carbapenem-resistant pathogens. © 2016 APMIS.

In this article we employ a trait activation framework to examine how unfairness perceptions influence narcissistic leaders' self-interested behavior, and the downstream implications of these effects for employees' pro-social and voice behaviors. Specifically, we propose that narcissistic leaders are particularly likely to engage in self-interested behavior when they perceive that their organizations treat them unfairly, and that this self-interested behavior in turn decreases followers' pro-social behavior and voice. Data from a multisource, time-lagged survey of 211 team leaders and 1,205 subordinates provided support for the hypothesized model. Implications for theory and practice are discussed.

Klebsiella pneumoniae is considered an opportunistic pathogen and an important agent of nosocomial and community infections. It presents the ability to capture and harbour several antimicrobial resistance genes and, in this context, the extensive use of carbapenems to treat serious infections has been responsible for the selection of several resistance genes. This study reports the draft genome sequence of a KPC-2-producing K. pneumoniae strain (Kp10) simultaneously harbouring bla CTX-M-15 and bla CTX-M-59 genes isolated from urine culture of a patient with Parkinson's disease. Classical microbiological methods were applied to isolate and identify the strain, and PCR and sequencing were used to identify and characterise the genes and the genetic environment. Whole-genome sequencing (WGS) was performed using a Nextera XT DNA library and a NextSeq platform. WGS analysis revealed the presence of 5915 coding genes, 46 RNA-encoding genes and 255 pseudogenes. Kp10 belonged to sequence type 340 (ST340) of clonal complex 258 (CC258) and carried 20 transferable genes associated with antimicrobial resistance, comprising seven drug classes. Although the simultaneous presence of different bla CTX-M genes in the same strain is rarely reported, the bla KPC-2 , bla CTX-M-15 and bla CTX-M-59 genes were not associated with the same genetic mobile structure in Kp10. These results confirm the capacity of K. pneumoniae to harbour several antimicrobial resistance genes. Thus, this draft genome could help in future epidemiological studies regarding the dissemination of clinically relevant resistance genes.

Chromosome-encoded beta-lactamases of Shewanella spp. have been indicated as probable progenitors of bla OXA-48 -like genes. However, these have been detected in few Shewanella spp. and dissemination mechanisms are unclear. Thus, our main objective was to confirm the role of Shewanella species as progenitors of bla OXA-48 -like genes. In silico analysis of Shewanella genomes was performed to detect bla OXA-48 -like genes and context, and 43 environmental Shewanella spp. were characterised. Clonal relatedness was determined by BOX-PCR. Phylogenetic affiliation was assessed by 16S rDNA and gyrB sequencing. Antibiotic susceptibility phenotypes were determined. The bla OXA-48 -like genes and genetic context were inspected by PCR, hybridisation and sequence analysis. Gene variants were cloned in Escherichia coli and MICs were determined. Shewanella isolates were screened for integrons, plasmids and insertion sequences. Analysis of Shewanella spp. genomes showed that putative bla OXA-48 -like is present in the majority and in an identical context. Isolates presenting unique BOX profiles affiliated with 11 Shewanella spp. bla OXA-48 -like genes were detected in 22 isolates from 6 species. Genes encoded enzymes identical to OXA-48, OXA-204, OXA-181, and 7 new variants differing from OXA-48 from 2 to 82 amino acids. IS1999 was detected in 24 isolates, although not in the vicinity of bla OXA-48 genes. Recombinant E. coli strains presented altered MICs. The presence/absence of bla OXA-48 -like genes was species-related. Gene variants encoded enzymes with hydrolytic spectra similar to OXA-48-like from non-shewanellae. From the mobile elements previously described in association with bla OXA-48 -like genes, only the IS1999 was found in Shewanella, which indicates its relevance in bla OXA-48 -like genes transfer to other hosts.

Acinetobacter baumannii is one of the major threats in clinical infections due to its antibiotic resistance ability. It shows increasing resistance to carbapenems, mainly due to β-lactamase mediated mechanisms. The aim of this study was to investigate carbapenem resistance (CR) profiles and analyze β-lactamases genes composition of clinical A. baumannii strains from a teaching hospital in Xi'an. The resistance patterns to imipenem and meropenem were checked for 51 clinical A. baumannii strains. The existence of 15 β-lactamases genes was detected by polymerase chain reaction (PCR), and the positive genes were sequenced. The correlation between PCR-positive genes and CR phenotype was analyzed using Chi-square test and contingency coefficient. The expressions of PCR-positive genes were investigated. Forty-five out of 51 strains were resistant to imipenem and meropenem. blaTEM, blaOXA-23-like, and blaOXA-51-like were positive among 15 β-lactamases genes, and TEM-1, OXA-23, and OXA-66/69 were their subtypes. TEM and OXA-23-like only showed up in CR isolates, with the occurrence rate of 91.1% and 97.8%, respectively, whereas OXA-51-like appeared in all strains. ISAba1 was present in the upstream of OXA-23-like, but absent from that of OXA-51-like in our strains. OXA-23-like had highest relationship with CR, followed by TEM, but OXA-51-like had no correlation. This was verified by RT-qPCR that the expression was positive for OXA-23 and TEM-1, but negative for OXA-66/-69. A high rate of CR A. baumannii was detected in this study. Coexistence of TEM, OXA-23-like, and OXA-51-like was the primary resistance profile. The expressions of OXA-23-like and TEM genes were closely related with CR, while OXA-51-like had no contribution to the CR phenotype.

To characterize bla(CTX-M) IncFII plasmids and clones of Escherichia coli from cats and dogs and to compare them with bla(CTX-M) IncFII plasmids reported in humans. From December 2006 to April 2010, 518 E. coli isolates from clinical infections in cats and dogs were screened for extended-spectrum β-lactamase (ESBL) production. Antimicrobial susceptibility was performed by disc diffusion and resistance genes were identified by PCR and sequencing. Plasmids were characterized using PCR-based replicon typing and sub-typing schemes, restriction fragment length polymorphism analysis, S1-PFGE and Southern hybridization. Isolates were characterized by PFGE, phylogenetic grouping, O25b typing and multilocus sequence typing. Nineteen E. coli isolates (3.7%) produced ESBLs, of which 14 (74%) carried bla(CTX-M) IncFII plasmids. The bla(CTX-M) gene was predominant and located on F31:A4:B1, F36:A4:B1 or F36:A1:B20 plasmids, abundantly reported in humans. The bla(CTX-M) F22:A1:B20 or F2:A2:B20 plasmids were also found. Different sequence types (STs) were identified, such as ST10, ST410, ST359, ST617 and ST224. Only one E. coli isolate belonged to the ST131 E. coli clone and carried a bla(CTX-M) F2:A2:B20 plasmid. This is the first known extensive study on ESBL-producing E. coli isolates from pets in France. The ST131 clone was rare. However, the predominance of human-like bla(CTX-M) IncFII plasmids suggests exchanges of these plasmids with the human reservoir.

Team leadership: network differences in women's and men's instrumental and expressive relations.
Webster, C; Grusky, O; Podus, D; Young, A
1999-01-01
Recent studies have emphasised differences in leadership styles between women and men. Women have an "interactive" leadership style while men are more "directive" and "authoritative." Social network analysis is used to examine differences in eight mental health case management teams, half formally supervised by women and half by men. The techniques used are graphical displays and measures of centrality. Results show male leaders as the most central team member for both instrumental and expressive relations. Female leaders, however, do not adhere to a single leadership style. Team centralisation also differs with gender composition of teams influencing leadership differences.

The ability to effectively exchange information and develop trusting, collaborative relationships across disciplinary boundaries is essential for 21st century scientists charged with solving complex and large-scale societal and environmental challenges, yet these communication skills are rarely taught. Here, we describe an adaptable training program designed to increase the capacity of scientists to engage in information exchange and relationship development in team science settings. A pilot of the program, developed by a leader in ecological network science, the Global Lake Ecological Observatory Network (GLEON), indicates that the training program resulted in improvement in early career scientists’ confidence in team-based network science collaborations within and outside of the program. Fellows in the program navigated human-network challenges, expanded communication skills, and improved their ability to build professional relationships, all in the context of producing collaborative scientific outcomes. Here, we describe the rationale for key communication training elements and provide evidence that such training is effective in building essential team science skills.

Team dynamics within quality improvement teams: a scoping review.
Rowland, Paula; Lising, Dean; Sinclair, Lynne; Baker, G Ross
2018-03-31
This scoping review examines what is known about the processes of quality improvement (QI) teams, particularly related to how teams impact outcomes. The aim is to provide research-informed guidance for QI leaders and to inform future research questions. Databases searched included: MedLINE, EMBASE, CINAHL, Web of Science and SCOPUS. Eligible publications were written in English, published between 1999 and 2016. Articles were included in the review if they examined processes of the QI team, were related to healthcare QI and were primary research studies. Studies were excluded if they had insufficient detail regarding QI team processes. Descriptive detail extracted included: authors, geographical region and health sector. The Integrated (Health Care) Team Effectiveness Model was used to synthesize findings of studies along domains of team effectiveness: task design, team process, psychosocial traits and organizational context. Over two stages of searching, 4813 citations were reviewed. Of those, 48 full-text articles are included in the synthesis. This review demonstrates that QI teams are not immune from dysfunction. Further, a dysfunctional QI team is not likely to influence practice. However, a functional QI team alone is unlikely to create change. A positive QI team dynamic may be a necessary but insufficient condition for implementing QI strategies. Areas for further research include: interactions between QI teams and clinical microsystems, understanding the role of interprofessional representation on QI teams and exploring interactions between QI team task, composition and process.

Proteus mirabilis (P. mirabilis) is one of Gram-negative pathogens encountered in clinical specimens. A clinical isolate (TRP41) of P. mirabilis was isolated from a Turkish patient in Turkey. The isolate was identified using the API 32GN system and 16S rRNA gene sequencing and it was found resistant to ampicillin/sulbactam, piperacillin, tetracycline, and trimethoprim/sulfamethoxazole. This isolate was harboring a Class 1 integron gene cassette and its DNA sequence analysis revealed a novel blaOXA variant exhibiting one amino acid substitution (Asn266Ile) from blaOXA-1 . This new variant of OXA was located on Class 1 integron together with aadA1 gene encoding aminoglycoside-modifying enzymes. According to sequence records, the new variant was named as blaOXA-320 . Cassette array and size of integron were found as blaOXA-320 -aadA1 and 2086 bp, respectively. The blaOXA-320 gene is not transferable according to conjugation experiment. In this study, we report the first identification of blaOXA-320 -aadA1 gene cassette, a novel variant of Class D β-lactamase, in P. mirabilis from Turkey. © 2014 WILEY-VCH Verlag GmbH & Co.

We investigated the relationships between leaders' and their followers' psychological capital and organizational identification in a Chinese community. Participants included 423 followers on 34 work teams, each with its respective team leader. Hierarchical linear models (HLM) were used in the analyses to delineate the relationships among participants' demographic background (gender, age, marital status, and educational level), human capital, and tenure. The results revealed that leaders' psychological capital positively influenced their followers' psychological capital through the mediation effect of enhancing followers' organizational identification. The implications of these findings, the study's limitations, and directions for future research are discussed. PMID:29075218

Salmonella enterica is one of the most common bacterial causes of foodborne illness, and nontyphoidal Salmonella is estimated to cause ∼1.2 million illnesses in the United States each year. Plasmids are mobile genetic elements that play a critical role in the dissemination of antimicrobial resistance determinants. AmpC-type CMY β-lactamases (bla(CMY)) confer resistance to extended-spectrum cephalosporins and β-lactam/β-lactamase inhibitor combinations and are commonly plasmid-encoded. A variety of plasmids have been shown to encode CMY β-lactamases and certain plasmids may be associated with particular Salmonella serotypes or environmental sources. In this study, we characterized bla(CMY) β-lactamase-encoding plasmids among Salmonella isolates. Isolates of Salmonella from specimens collected from humans in 2007 were submitted to the Centers for Disease Control and Prevention National Antimicrobial Resistance Monitoring System laboratory for susceptibility testing. Three percent (65/2161) of Salmonella isolates displayed resistance to ceftriaxone (minimum inhibitory concentration [MIC] ≥4 mg/L) and amoxicillin/clavulanic acid (MIC ≥32 mg/L), a combination associated with the presence of a bla(CMY) mechanism of resistance. Sixty-four (98.5%) isolates were polymerase chain reaction-positive for bla(CMY) genes. Transformation and conjugation studies showed that 95% (61/64) of the bla(CMY) genes were plasmid-encoded. Most of the bla(CMY)-positive isolates were serotype Typhimurium, Newport, Heidelberg, and Agona. Forty-three plasmids were replicon type IncA/C, 15 IncI1, 2 contained multiple replicon loci, and 1 was untypeable. IncI1 plasmids conferred only the bla(CMY)-associated resistance phenotype, whereas IncA/C plasmids conferred additional multi-drug resistance (MDR) phenotypes to drugs such as chloramphenicol, sulfisoxazole, and tetracycline. Most of the IncI1 plasmids (12/15) were sequence type 12 by plasmid multi-locus sequence typing. CMY

The impact of team building on communication and job satisfaction of nursing staff.
Amos, Mary Anne; Hu, Jie; Herrick, Charlotte A
2005-01-01
A series of team-building activities were conducted on a medical-surgical unit and their impact on staff's communication and job satisfaction was examined. Forty-four unit personnel participated in the interventions. Staff communication and job satisfaction were measured before and after the intervention. The findings linked team-building activities with improved staff communication and job satisfaction. Team-building strategies assisted the nurse leader/manager to build an effective work team by strengthening communication and interpersonal relationships so that the staff could function as a more cohesive group. Staff development consultants can help nurse managers become more effective team leaders by identifying the necessary resources and by helping to plan and coordinate team-building strategies.

Mental health treatment teams and leadership: a systems model.
Yank, G R; Barber, J W; Spradlin, W W
1994-10-01
Mental health treatment teams are living systems at the group level and comprise key productive subsystems of organizations providing mental health care. Effective treatment teams, like effective organizations, are anticipatory systems that contain subsystems that model and predict future system and environmental conditions and enable responses that increase system viability. A systems analysis of treatment teams highlights their potential instability due to their tendencies to regress toward dysfunctional partial systems and their active maintenance in nonequilibrium steady states with their organizational and external environments. Team subsystems are analyzed from the viewpoints of system processes and also with regard to individuals and their roles. Boundary processes are central to effective team functioning, assure constancy of team membership, and regulate the team's interfaces with its parent agency and with the external environment. Various causes and forms of disturbed information processing within hierarchical organizations are examined, and their effects at the treatment team level are discussed. The conclusion of the discussion focuses on team leadership and how leadership expands upon the concept of the decider subsystem to include role and personal factors to the team's leaders, and functions that are anticipatory and integrative in nature. Effective leaders must set appropriate thresholds for feedback regulation processes, and balance several pairs of seemingly opposing forces, including homeostasis and development, role differentiation and role overlap, and personal accountability and empowerment of others.

Carbapenem-resistant Acinetobacter baumannii (CR-AB) causes serious nosocomial infections, especially in ICU wards of hospitals, worldwide. Expression of blaOXA genes is the chief mechanism of conferring carbapenem resistance among CR-AB. Although some blaOXA genes have been studied among CR-AB isolates from Iran, their blaOXA-23-like genes have not been investigated. We used a multiplex-PCR to detect Ambler class A, B, and D carbapenemases of 85 isolates, and determined that 34 harbored blaOXA-23-like genes. Amplified fragment length polymorphism (AFLP) genotyping, followed by DNA sequencing of blaOXA-23-like amplicons of CR-AB from each AFLP group was used to characterize their blaOXA-23-like genes. We also assessed the antimicrobial susceptibility pattern of CR-AB isolates, and tested whether they harbored insertion sequences ISAba1 and ISAba4. Sequence comparison with reference strain A. baumannii (NCTC12156) revealed five types of mutations in blaOXA-23-like genes; including one novel variant and four mutants that were already reported from China and the USA. All of the blaOXA-23-like genes mutations were associated with increased minimum inhibitory concentrations (MICs) against imipenem. ISAba1 and ISAba4 sequences were detected upstream of blaOXA-23 genes in 19 and 7% of isolates, respectively. The isolation of CR-AB with new blaOXA-23 mutations including some that have been reported from the USA and China highlights CR-AB pervasive distribution, which underscores the importance of concerted national and global efforts to control the spread of CR-AB isolates worldwide.

Discrepancies, or perceptual distance, between leaders' self-ratings and followers' ratings of the leader are common but usually go unrecognized. Research on discrepancies is limited, but there is evidence that discrepancies are associated with organizational context. This study examined the association of leader-follower discrepancies in Implementation Leadership Scale (ILS) ratings of mental health clinic leaders and the association of those discrepancies with organizational climate for involvement and performance feedback. Both involvement and performance feedback are important for evidence-based practice (EBP) implementation in mental health. A total of 593 individuals-supervisors (leaders, N=80) and clinical service providers (followers, N=513)-completed surveys that included ratings of implementation leadership and organizational climate. Polynomial regression and response surface analyses were conducted to examine the associations of discrepancies in leader-follower ILS ratings with organizational involvement climate and performance feedback climate, aspects of climate likely to support EBP implementation. Both involvement climate and performance feedback climate were highest where leaders rated themselves low on the ILS and their followers rated those leaders high on the ILS ("humble leaders"). Teams with "humble leaders" showed more positive organizational climate for involvement and for performance feedback, contextual factors important during EBP implementation and sustainment. Discrepancy in leader and follower ratings of implementation leadership should be a consideration in understanding and improving leadership and organizational climate for mental health services and for EBP implementation and sustainment in mental health and other allied health settings.

Conceptualizing clinical nurse leader practice: an interpretive synthesis.
Bender, Miriam
2016-01-01
The Institute of Medicine's Future of Nursing report identifies the clinical nurse leader as an innovative new role for meeting higher health-care quality standards. However, specific clinical nurse leader practices influencing documented quality outcomes remain unclear. Lack of practice clarity limits the ability to articulate, implement and measure clinical nurse leader-specific practice and quality outcomes. Interpretive synthesis design and grounded theory analysis were used to develop a theoretical understanding of clinical nurse leader practice that can facilitate systematic and replicable implementation across health-care settings. The core phenomenon of clinical nurse leader practice is continuous clinical leadership, which involves four fundamental activities: facilitating effective ongoing communication; strengthening intra and interprofessional relationships; building and sustaining teams; and supporting staff engagement. Clinical nurse leaders continuously communicate and develop relationships within and across professions to promote and sustain information exchange, engagement, teamwork and effective care processes at the microsystem level. Clinical nurse leader-integrated care delivery systems highlight the benefits of nurse-led models of care for transforming health-care quality. Managers can use this study's findings to frame an implementation strategy that addresses theoretical domains of clinical nurse leader practice to help ensure practice success. © 2015 John Wiley & Sons Ltd.

Developing our leaders in the future.
Hackett, M; Spurgeon, P
1998-01-01
The role of the chief executive in a transformed organisation is an extremely challenging one. The development of vision, building a commitment to it and communicating it constantly are key skills for a chief executive. However, the need to build and empower the stakeholders within and outside the organisation to support the changes required to deliver the vision requires leaders who can connect with a wide range of people and build alliances and partnerships to secure organisational success. A passion for understanding human intervention and behaviour is needed to encourage, cajole and drive teams and individuals to own and commit to change and a new direction. This requires leaders who have imagination and creativity--who seek connections and thread them together to create order out of incoherence. These skills are not taught in schools or textbooks, but are probably innate. They are what separate leaders from the rest. These skills need to be developed. A movement towards encouraging experimentation, career transfers and more individuality is needed if capable leaders of the future are to appear.

Nurses' views on the characteristics of an effective leader.
Feltner, Arta; Mitchell, Barbara; Norris, Elfi; Wolfle, Clara
2008-02-01
Effective leadership can promote a satisfying and productive work environment in which staff members positively contribute to the success of the organization. Nurses at a magnet hospital in Florida undertook a project to determine what staff nurses believed were the characteristics of an effective leader. Using one-on-one interviews and surveys, the project team discovered that the most highly ranked qualities and characteristics of an effective leader included effective communication skills, fairness, and knowledge about staff members' jobs.

Effect of different simulated altitudes on repeat-sprint performance in team-sport athletes.
Goods P, S R; Dawson, Brian T; Landers, Grant J; Gore, Christopher J; Peeling, Peter
2014-09-01
This study aimed to assess the impact of 3 heights of simulated altitude exposure on repeat-sprint performance in team-sport athletes. Ten trained male team-sport athletes completed 3 sets of repeated sprints (9 × 4 s) on a nonmotorized treadmill at sea level and at simulated altitudes of 2000, 3000, and 4000 m. Participants completed 4 trials in a random order over 4 wk, with mean power output (MPO), peak power output (PPO), blood lactate concentration (Bla), and oxygen saturation (SaO2) recorded after each set. Each increase in simulated altitude corresponded with a significant decrease in SaO2. Total work across all sets was highest at sea level and correspondingly lower at each successive altitude (P < .05; sea level < 2000 m < 3000 m < 4000 m). In the first set, MPO was reduced only at 4000 m, but for subsequent sets, decreases in MPO were observed at all altitudes (P < .05; 2000 m < 3000 m < 4000 m). PPO was maintained in all sets except for set 3 at 4000 m (P < .05; vs sea level and 2000 m). BLa levels were highest at 4000 m and significantly greater (P < .05) than at sea level after all sets. These results suggest that "higher may not be better," as a simulated altitude of 4000 m may potentially blunt absolute training quality. Therefore, it is recommended that a moderate simulated altitude (2000-3000 m) be employed when implementing intermittent hypoxic repeat-sprint training for team-sport athletes.

Pathology Residents Comprise Inspection Team for a CAP Self-Inspection.
Beal, Stacy G; Kresak, Jesse L; Yachnis, Anthony T
2017-01-01
We report our experience at the University of Florida in which residents and fellows served as the inspection team for a College of American Pathologists (CAP) self-inspection. We aimed to determine whether the CAP self-inspection could serve as a learning opportunity for pathology residents and fellows. To prepare for the inspection, we provided a series of 4 lunchtime seminars covering numerous laboratory management topics relating to inspections and laboratory quality. Preparation for the inspection began approximately 4 months prior to the date of the inspection. The intent was to simulate a CAP peer inspection, with the exception that the date was announced. The associate residency program director served as the team leader. All residents and fellows completed inspector training provided by CAP, and the team leader completed the team leader training. A 20 question pre- and posttest was administered; additionally, an anonymous survey was given after the inspection. The residents' and fellows' posttest scores were an average of 15% higher than on the pretest ( P < .01). The surveys as well as subjective comments were overwhelmingly positive. In conclusion, the resident's and fellow's experience as an inspector during a CAP self-inspection was a useful tool to learn accreditation and laboratory management.

Empowerment in nurse leader groups in middle management: a quantitative comparative investigation.
Spencer, Caroline; McLaren, Susan
2017-01-01
The aim was to investigate structural empowerment in nurse leaders in middle management positions. Objectives were to determine levels of empowerment of nurse leaders and to compare levels of empowerment between nurse leader groups. Access to formal and informal power, opportunity, resources, information and support are determinants of structural empowerment. Empowerment of nurse leaders in middle management positions is vital given their roles in enabling nursing teams to deliver high-quality care, benefitting both patient and workforce outcomes. Quantitative component of a mixed methods study using survey principles. The Conditions of Work Effectiveness Questionnaire II was distributed to the total population (n = 517) of nurse leaders in an NHS Foundation Trust in England. Nurse leader groups comprised unit leaders (sisters, matrons) and senior staff nurses. Quantitative data entered on spss v 17/18, were analysed using descriptive and inferential statistics. Overall, the unit response rate was 44·1% (n = 228). Levels of total and global empowerment were moderate and moderate to high respectively. Groups did not differ significantly on these parameters or on five elements of total empowerment, but significantly higher scores were found for unit leaders' access to information. Significantly higher scores were found for senior staff nurses on selected aspects of informal power and access to resources, but scores were significantly lower than unit leaders for components of support. A moderately empowered population of nurse leaders differed in relation to access to information, aspects of support, resources and informal power, reflecting differences in roles, spheres of responsibility, hierarchical position and the constraints on empowerment imposed on unit leaders by financial and resource pressures. Empowerment of nurse leaders in middle management is vital in enabling nursing teams to deliver high-quality care. Roles, spheres of responsibility, hierarchical

In this study, 417 Escherichia coli isolates from defined disease conditions of companion and farm animals collected in the BfT-GermVet study were investigated for the presence of extended-spectrum β-lactamase (ESBL) genes. Three ESBL-producing E. coli isolates were identified among the 100 ampicillin-resistant isolates. The E. coli isolates 168 and 246, of canine and porcine origins, respectively, harbored blaCTX-M-1, and the canine isolate 913 harbored blaCTX-M-15, as confirmed by PCR and sequence analysis. The isolates 168 and 246 belonged to the novel multilocus sequence typing (MLST) types ST1576 and ST1153, respectively, while isolate 913 had the MLST type ST410. The ESBL genes were located on structurally related IncN plasmids in isolates 168 and 246 and on an IncF plasmid in isolate 913. The blaCTX-M-1 upstream regions of plasmids pCTX168 and pCTX246 were similar, whereas the downstream regions showed structural differences. The genetic environment of the blaCTX-M-15 gene on plasmid pCTX913 differed distinctly from that of both blaCTX-M-1 genes. Detailed sequence analysis showed that the integration of insertion sequences, as well as interplasmid recombination events, accounted for the structural variability in the blaCTX-M gene regions.

Opportunities for improving patient care through lateral integration: the clinical nurse leader.
Begun, James W; Tornabeni, Jolene; White, Kenneth R
2006-01-01
Today, healthcare organizations are faced with the growing realization that functional and professional silos within the organization are counter to the provision of efficient and effective patient care and are fertile grounds for errors or sentinel events to occur. The improvement of patient care and prevention of errors require that collaboration among professionals occur at the patient care delivery level, not just within the leadership team. A new nursing role-the clinical nurse leader, the first new nursing role advanced nationally in more than three decades--currently is under development in more than 180 pilot healthcare delivery sites across the United States and Puerto Rico. The clinical nurse leader is a master's-prepared nurse who assumes accountability for healthcare outcomes for a specific group of clients within a unit or setting through the assimilation and application of research-based information to design, implement, and evaluate client plans of care. The clinical nurse leader serves as a lateral integrator for the healthcare team and facilitates, coordinates, and oversees the care provided by the healthcare team. Healthcare administrators should seize the opportunity to work with nurses in healthcare delivery organizations to influence the early evolution and diffusion of this new role.

A double standard when group members behave badly: transgression credit to ingroup leaders.
Abrams, Dominic; Randsley de Moura, Georgina; Travaglino, Giovanni A
2013-11-01
This research tested the hypothesis that people forgive serious transgressions by ingroup leaders but not by other group members or outgroup leaders. They apply a double standard in judgments of ingroup leaders. A series of studies (N = 623), using an array of different ingroups and outgroups, tested how group members judged ingroup or outgroup leaders and nonleaders who unexpectedly transgressed or did not transgress in important intergroup scenarios. Experiments 1, 2, and 4 focused on captains and players in either soccer or netball sports competitions. Across studies, transgressive captains of ingroup teams were evaluated more favorably than captains from outgroup teams and (Experiments 1, 2, and 4) more favorably than transgressive ingroup players. Experiment 3 demonstrated the double standard in a minimal group paradigm. Experiment 5 showed that the double standard is only applied if the leader is perceived as serving the group's interest. Across studies, the double standard is evident in evaluations toward, inclusion and punishment of, and rewards to the transgressive targets. Implications for sport, politics, and business and intergroup conflict are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

2018-04-01
Preparation, characterization and catalytic activity of ZrO2/bamboo leaves ash (BLA) catalyst for conversion of rice bran oil to biodiesel have been investigated. The catalyst was prepared by impregnation method of ZrOCl2 as ZrO2 precursor with BLA at a theoretical content of 20% wt. followed by calcination. The physicochemical properties of the catalyst material were characterized by x-ray diffraction (XRD), FTIR and surface acidity measurement. Activity test of materials in biodiesel conversion of rice bran oil was used by reflux method and microwave (MW) assisted method. Reaction variables studied in the investigation were the effect of catalyst weight and time of MW irradiation compared with the use reflux method. The results showed that ZrO2/BLA catalyst exhibited competitively effective and efficient processes for the production of biodiesel. The reflux method demonstrated an higher conversion (%) compared to MW method, however MW method showed the better reusable properties.

Objectives: The aim of this study is to investigate the prevalence of blaTEM and nim genes that encode resistance to β-lactams and nitroimidazoles, respectively, in the oral cavity of systemically healthy Greek subjects. Materials and Methodology: After screening 720 potentially eligible subjects, 154 subjects were recruited for the study, including 50 periodontally healthy patients, 52 cases of gingivitis and 52 cases of chronic periodontitis. The clinical parameters were assessed with an automated probe. Various samples were collected from the tongue, first molars and pockets >6mm, and analysed by polymerase chain reaction-amplification of the blaTEM and nim genes, using primers and conditions previously described in the literature. Results: There was a high rate of detection of blaTEM in plaque and tongue samples alike in all periodontal conditions (37% of plaque and 60% of tongue samples, and 71% of participants). The blaTEM gene was detected more frequently in the tongue samples of the periodontally healthy (56%) and chronic periodontitis (62%) groups compared to the plaque samples from the same groups (36% and 29%, respectively; z-test with Bonferroni corrections-tests, P<0.05). The nim gene was not detected in any of the 343 samples analysed. Conclusion: The oral cavity of Greek subjects often harbours blaTEM but not nim genes, and therefore the antimicrobial activity of β-lactams might be compromised. PMID:27099637

This research aimed to introduce social network analysis as a novel technique in sports teams to identify the attributes of high-quality athlete leadership, both at the individual and at the team level. Study 1 included 25 sports teams (N = 308 athletes) and focused on athletes' general leadership quality. Study 2 comprised 21 sports teams (N = 267 athletes) and focused on athletes' specific leadership quality as a task, motivational, social, and external leader. The extent to which athletes felt connected with their leader proved to be most predictive for athletes' perceptions of that leader's quality on each leadership role. Also at the team level, teams with higher athlete leadership quality were more strongly connected. We conclude that social network analysis constitutes a valuable tool to provide more insight in the attributes of high-quality leadership both at the individual and at the team level.

Nurse leader resilience: career defining moments.
Cline, Susan
2015-01-01
Resilience is an essential component of effective nursing leadership. It is defined as the ability to survive and thrive in the face of adversity. Resilience can be developed and internalized as a measure to improve retention and reduce burnout. Nurse leaders at all levels should develop these competencies to survive and thrive in an increasingly complex health care environment. Building positive relationships, maintaining positivity, developing emotional insight, creating work-life balance, and reflecting on successes and challenges are effective strategies for resilience building. Nurse leaders have a professional obligation to develop resilience in themselves, the teams they supervise, and the organization as a whole. Additional benefits include reduced turnover, reduced cost, and improved quality outcomes through organizational mindfulness.

This naturalistic study focused on the perceptions of leadership and student performance in science from campus leaders in three purposefully selected secondary campuses of ninth through twelfth grades. Each school had experienced an improvement in student passing rates on the science TAKS test that exceeded the state's percent improvement in passing rates for the past three years and had a record of improving science TAKS scores for the period of 2003 to 2008 exceeding fifteen percentage points. The qualitative research technique of multi-case studies design was used. Data was collected through semi-structured, in-depth interviews with four campus leaders from each of the selected schools. These campus leaders included campus administrators, science department chairs, and grade-level team leaders. A framework of transformational leadership was utilized in the analysis of the data generated from the interviews. The perception from the campus leaders was that leadership has a positive impact on student success in science. The findings indicated perceptions of leadership from the campus leaders had certain leadership practices in common. These included (a) clear vision and goals from the campus principal, (b) high performance expectations for teachers and students from administrators and science department leaders, (c) encouragement and support from campus administrators and science department leaders to develop new programs to address problem areas, (d) emphasis on collaborative teams, and (e) open door policy from administrators.

Background The importance of leadership is recognized in surgery, but the specific impact of leadership style on team behavior is not well understood. In other industries, leadership is a well-characterized construct. One dominant theory proposes that transactional (task-focused) leaders achieve minimum standards, whereas transformational (team-oriented) leaders inspire performance beyond expectations. Study Design We video-recorded 5 surgeons performing complex operations. Each surgeon was scored on the Multifactor Leadership Questionnaire, a validated method for scoring transformational and transactional leadership style, by an organizational psychologist and a surgeon-researcher. Independent coders assessed surgeons' leadership behaviors according to the Surgical Leadership Inventory and team behaviors (information-sharing, cooperative, and voice behaviors). All coders were blinded. Leadership style (MLQ) was correlated with surgeon behavior (SLI) and team behavior using Poisson regression, controlling for time and the total number of behaviors, respectively. Results All surgeons scored similarly on transactional leadership (2.38-2.69), but varied more widely on transformational leadership (1.98-3.60). Each 1-point increase in transformational score corresponded to 3× more information-sharing behaviors (p<0.0001) and 5.4× more voice behaviors (p=0.0005) amongst the team. With each 1-point increase in transformational score, leaders displayed 10× more supportive behaviors (p<0.0001) and 12.5× less frequently displayed poor behaviors (p<0.0001). Excerpts of representative dialogue are included for illustration. Conclusions We provide a framework for evaluating surgeons' leadership and its impact on team performance in the OR. As in other fields, our data suggest that transformational leadership is associated with improved team behavior. Surgeon leadership development therefore has the potential to improve the efficiency and safety of operative care. PMID

The emergence and spread of New Delhi metallo-β-lactamase-producing Enterobacteriaceae has been a serious challenge to manage in the clinic due to its rapid dissemination of multi-drug resistance worldwide. As one main type of carbapenemases, New Delhi metallo-β-lactamase (NDM)is able to confer resistance to almost all β-lactams, including carbapenems, in Enterobacteriaceae . Recently, New Delhi metallo-β-lactamase-5 attracted extensive attention because of increased resistance to carbapenems and widespread dissemination. However, the dissemination mechanism of bla NDM-5 gene remains unclear. A total of 224 carbapenem-resistant Enterobacteriaceae isolates (CRE) were collected from different hospitals in Zhejiang province. NDM-5-positive isolates were identified and subjected to genotyping, susceptibility testing, and clinical data analysis. We established the genetic location of bla NDM-5 with southern blot hybridisation, and analysed plasmids containing bla NDM-5 with filter mating and DNA sequencing. Eleven New Delhi metallo-β-lactamase-5 (NDM-5)-producing strains were identified, including 9 Escherichia coli strains, 1 Klebsiella pneumoniae strain, and 1 Citrobacter freundii strain. No epidemiological links for E. coli isolates were identified by multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE). S1-PFGE and southern blot suggested that the bla NDM-5 gene was located on a 46-kb IncX3-type plasmid in all isolates. Nine of the 11 isolates (81.8%) tested could successfully transfer their carbapenem-resistant phenotype to E. coli strain C600. Moreover, sequence analysis further showed that this plasmid possessed high sequence similarity to most of previously reported bla NDM-5 -habouring plasmids in China. The present data in this study showed the IncX3 type plasmid played an important role in the dissemination of bla NDM-5 in Enterobacteriaceae . In addition, to the best of our knowledge, this report is the first to isolate both E

Objectives Discrepancies between leaders' self-ratings and follower ratings of the leader are common but usually go unrecognized. Research on discrepancies is limited but there is evidence that discrepancies are associated with organizational context. This study examined the association of leader-follower discrepancies in Implementation Leadership Scale (ILS) ratings of mental health clinic leaders, and the association of those discrepancies with organizational climate for involvement and performance feedback. Both involvement and performance feedback may be important for evidence-based practice implementation in mental health. Methods A total of 593 supervisors (i.e., leaders, n=80) and clinical service providers (i.e., followers, n=513) completed surveys including ratings of implementation leadership and organizational climate. Polynomial regression and response surface analyses were conducted to examine the associations of discrepancies in leader-follower ILS ratings with organizational involvement climate and performance feedback climate, aspects of climate likely to support EBP implementation. Results Both involvement climate and performance feedback climate were highest where leaders rated themselves low on the ILS and their followers rated those leaders high on the ILS (i.e., “humble leaders”). Conclusions Teams with “humble leaders” showed more positive organizational climate for involvement and for performance feedback, contextual factors important during EBP implementation and sustainment. Discrepancy in leader and follower ratings of implementation leadership should be a consideration in understanding and improving leadership and organizational climate for mental health services and for evidence-based practice implementation and sustainment in mental health and other allied health settings.

The membrane-spanning protein BlaR is essential for the induction of beta-lactamase in Bacillus licheniformis. Its nature and location were confirmed by the use of an antiserum specific for its carboxy-terminal penicillin sensor, its function was studied by genetic dissection, and the structure of the penicillin sensor was derived from hydrophobic cluster analysis of the amino acid sequence by using, as a reference, the class A beta-lactamases with known three-dimensional structures. During the first 2 h after the addition of the beta-lactam inducer, full-size BlaR, bound to the plasma membrane, is produced, and then beta-lactamase is produced. By 2 h after induction, BlaR is present in various (membrane-bound and cytosolic) forms, and there is a gradual decrease in beta-lactamase production. The penicillin sensors of BlaR and the class D beta-lactamases show strong similarities in primary structures. They appear to have the same basic spatial disposition of secondary structures as that of the class A beta-lactamases, except that they lack several alpha helices and, therefore, have a partially uncovered five-stranded beta sheet and a more readily accessible active site. Alterations of BlaR affecting conserved secondary structures of the penicillin sensor and specific sites of the transducer annihilate beta-lactamase inducibility. Images PMID:1400165

Background Metallo-β-lactamase-production among Gram-negative bacteria, including Pseudomonas aeruginosa, has become a challenge for treatment of infections due to these resistant bacteria. Objectives The aim of the current study was to evaluate the metallo-β-lactamase-production and carriage of bla-VIM genes among carbapenem-resistant P. aeruginosa isolated from burn wound infections. Patients and Methods A cross-sectional study was conducted from September 2014 to July 2015. One hundred and fifty P. aeruginosa isolates were recovered from 600 patients with burn wound infections treated at Imam-Musa-Kazem Hospital in Isfahan city, Iran. Carbapenem-resistant P. aeruginosa isolates were screened by disk diffusion using CLSI guidelines. Metallo-β-lactamase-producing P. aeruginosa isolates were identified using an imipenem-EDTA double disk synergy test (EDTA-IMP DDST). For detection of MBL genes including bla-VIM-1 and bla-VIM-2, polymerase chain reaction (PCR) methods and sequencing were used. Results Among the 150 P. aeruginosa isolates, 144 (96%) were resistant to imipenem by the disk diffusion method, all of which were identified as metallo-β-lactamase-producing P. aeruginosa isolates by EDTA-IMP DDST. Twenty-seven (18%) and 8 (5.5%) MBL-producing P. aeruginosa isolates harbored bla-VIM-1 and bla-VIM-2 genes, respectively. Conclusions Our findings showed a high occurrence of metallo-β-lactamase production among P. aeruginosa isolates in burn patient infections in our region. Also, there are P. aeruginosa isolates carrying the bla-VIM-1 and bla-VIM-2 genes in Isfahan province. PMID:28144604

The bla SHV-12 β-lactamase gene is one of the most prevalent genes conferring resistance to extended-spectrum β-lactams in Enterobacteriaceae disseminating within and between reservoirs, mostly via plasmid-mediated horizontal gene transfer. Yet, studies regarding the biology of plasmids encoding bla SHV-12 are very limited. In this study, we revealed the emergence of IncX3 plasmids alongside IncI1α/γ in bla SHV-12 in animal-related Escherichia coli isolates. Four representative bla SHV-12 -encoding IncX3 plasmids were selected for genome sequencing and further genetic and functional characterization. We report here the first complete sequences of IncX3 plasmids of animal origin and show that IncX3 plasmids exhibit remarkable synteny in their backbone, while the major differences lie in their bla SHV-12 -flanking region. Our findings indicate that plasmids of this subgroup are conjugative and highly stable, while they exert no fitness cost on their bacterial host. These favourable features might have contributed to the emergence of IncX3 amongst SHV-12-producing E. coli in the Netherlands, highlighting the epidemic potential of these plasmids.

Assessing the professional development needs of experienced nurse executive leaders.
Leach, Linda Searle; McFarland, Patricia
2014-01-01
The objective of this study was to identify the professional development topics that senior nurse leaders believe are important to their advancement and success. Senior/experienced nurse leaders at the executive level are able to influence the work environment of nurses and institutional and health policy. Their development needs are likely to reflect this and other contemporary healthcare issues and may be different from middle and frontline managers. A systematic way of assessing professional development needs for these nurse leaders is needed. A descriptive study using an online survey was distributed to a convenience sample of nurse leaders who were members of the Association of California Nurse Leaders (ACNL) or have participated in an ACNL program. Visionary leadership, leading complexity, and effective teams were the highest ranked leadership topics. Leading change, advancing health: The future of nursing, healthy work environments, and healthcare reform were also highly ranked topics. Executive-level nurse leaders are important to nurse retention, effective work environments, and leading change. Regular assessment and attention to the distinct professional development needs of executive-level nurse leaders are a valuable human capital investment.

To elucidate the mechanisms responsible for the diversity of beta-lactam resistance phenotypes among isolates of a VIM-1-producing Klebsiella pneumoniae (VPKP) strain that is endemic in Greek hospitals. Five VPKP clinical isolates were studied. MICs of beta-lactams were determined by agar dilution. PFGE of XbaI-digested genomic DNA was used for typing. Profiles of outer membrane proteins (OMPs) were determined by SDS-PAGE. Selected isolates were transformed with a plasmid encoding the Omp36K porin. beta-Lactamase activities were analysed by IEF and imipenem hydrolysis was assessed by spectrophotometry. VIM-1-encoding, self-transmissible plasmids were characterized by replicon typing, RFLP and hybridization with bla(VIM)- and IS26-specific probes. Characterization of integrons was performed by PCR, cloning and sequencing. Isolates exhibited highly similar PFGE patterns. Imipenem MICs were 2, 4, 16, 32 and 64 mg/L. The isolate with the highest imipenem MIC (Vipm-64) lacked a 36 kDa OMP. Expression of a cloned OmpK36 in this isolate reduced the imipenem MIC to susceptibility levels. Imipenem-hydrolysing activity was significantly higher in Vipm-16 as compared with the other isolates that expressed similar amounts of VIM-1. All isolates transferred beta-lactam resistance to Escherichia coli through conjugative, IncN plasmids that exhibited differences in the RFLP and hybridization patterns with bla(VIM)- and IS26-specific probes. The Vipm-16 plasmid, mediating the higher imipenem MICs among transconjugants, carried two copies of bla(VIM-1). Cloning and sequencing showed In-e541-like integrons truncated at the 5'CS by insertion of IS26 elements at two different positions. A VIM-1-producing strain of K. pneumoniae has evolved through OMP alterations and rearrangements in the bla(VIM-1)-carrying plasmid probably mediated by IS26, generating isolates with imipenem MICs ranging from susceptibility to resistance.

The World Health Organisation has advocated for comprehensive primary care teams, which include family physicians. However, despite (or because of) severe doctor shortages in Africa, there is insufficient clarity on the role of the family physician in the primary health care team. Instead there is a trend towards task shifting without thought for teamwork, which runs the risk of dangerous oversimplification. It is not clear how African leaders understand the challenges of implementing family medicine, especially in human resource terms. This study, therefore, sought to explore the views of academic and government leaders on critical human resource issues for implementation of family medicine in Africa. In this qualitative study, key academic and government leaders were purposively selected from sixteen African countries. In-depth interviews were conducted using an interview guide. All interviews were audio-recorded, transcribed and thematically analysed. There were 27 interviews conducted with 16 government and 11 academic leaders in nine Sub-Saharan African countries: Botswana, Democratic Republic of Congo, Ghana, Kenya, Malawi, Nigeria, Rwanda, South Africa and Uganda. Respondents spoke about: educating doctors in family medicine suited to Africa, including procedural skills and holistic care, to address the difficulty of recruiting and retaining doctors in rural and underserved areas; planning for primary health care teams, including family physicians; new supervisory models in primary health care; and general human resource management issues. Important milestones in African health care fail to specifically address the human resource issues of integrated primary health care teamwork that includes family physicians. Leaders interviewed in this study, however, proposed organising the district health system with a strong embrace of family medicine in Africa, especially with regard to providing clinical leadership in team-based primary health care.

The extensive use of β-lactam antibiotics has led to emergence and spread of extended-spectrum β-lactamases (ESBLs). This study was conducted to investigate the prevalence of 7 different ESBL genes (bla TEM , bla SHV , bla CTX-M , bla VEB , bla PER , bla GES , and bla OXA-10 ) and O25b-ST131 high-risk clone among 61 clinical isolates of Escherichia coli. Also, one broad-spectrum β-lactamase (bla OXA-1 ) was investigated. This study was also constructed to evaluate iodometric overlay method in detection of ESBL production. Phenotypic identification of E. coli isolates using API 20E revealed 18 distinct biotypes. DNA fingerprinting using enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) differentiated all isolates into 2 main phylogenetic groups with 60 distinct genetic profiles. Elevated values of minimal inhibitory concentration (MIC) 50 and MIC 90 for third- and fourth-generation cephalosporins were observed. Phenotypic tests revealed that 85.24% of isolates were ESBL producers. The incidence rates of bla TEM , bla SHV , bla CTX-M , bla GES , bla OXA-1 , and bla OXA-10 among E. coli ESBL producer phenotype were 69.23%, 25%, 96.15%, 3.85%, 11.54%, and 48%, respectively. On the other hand, bla VEB and bla PER were not detected. Sequencing of bla TEM and bla SHV revealed that bla TEM-214 and bla SHV-11 were the most prevalent variants. Group characterization of bla CTX-M revealed that bla CTX-M-1 was the most prevalent group of bla CTX-M family. It was found that 30.77% of E. coli ESBL producers belonged to O25b-ST131 clone harboring bla CTX-M-15 . This study concluded that iodometric overlay method was 100% sensitive in detection of ESBL production. To our knowledge, this is the first Egyptian study that declares the emergence of E. coli O25b-ST131 harboring bla GES .

Are you tired? Overcoming leadership styles that create leader fatigue.
Kerfoot, Karlene M
2013-01-01
Part of the culture of nursing is convincing everyone you are perpetually overworked and overwhelmed. The leadership style the leader chooses will determine whether he or she will be energized or overwhelmed. When the leader is unable and unwilling to surround him or herself with people who are more knowledgeable and astute, the level of stress and worry becomes unbearable. Relationships thrive when a structure is present. Your staff will be energized and empowered, and will reach incredible levels of productivity and the highest level of achievement possible. Doing "nothing" allows your staff to grow as people and as a team, and you will be free to do the work of the leader, and not be tired.

The role of trauma team leaders in missed injuries: does specialty matter?
Leeper, W Robert; Leeper, Terrence John; Vogt, Kelly Nancy; Charyk-Stewart, Tanya; Gray, Daryl Kenneth; Parry, Neil Geordie
2013-09-01
Previous studies have identified missed injuries as a common and potentially preventable occurrence in trauma care. Several patient- and injury-related variables have been identified, which predict for missed injuries; however, differences in rate and severity of missed injuries between surgeon and nonsurgeon trauma team leaders (TTLs) have not previously been reported. A retrospective review was conducted on a random sample of 10% of all trauma patients (Injury Severity Score [ISS] > 12) from 1999 to 2009 at a Canadian Level I trauma center. Missed injuries were defined as those identified greater than 24 hours after presentation and were independently adjudicated by two reviewers. TTLs were identified as either surgeons or nonsurgeons. Of our total trauma population of 2,956 patients, 300 charts were randomly pulled for detailed review. Missed injuries occurred in 46 patients (15%). Most common missed injuries were fractures (n = 32, 70%) and thoracic injuries (n = 23, 50%). The majority of missed injuries resulted in minor morbidity with only 5 (11%) requiring operative intervention. On univariate analysis, higher ISS (p < 0.01), higher maximum Abbreviated Injury Scale (MAIS) score of the thorax (p < 0.01), and nonsurgeon TTL status were predictive of missed injuries (p = 0.02). Multivariable logistic regression revealed that, after adjustment for age, ISS, and severe head injuries, the presence of a nonsurgeon TTL was associated with an increased odds of missed injury (odds ratio, 2.15; 95% confidence interval, 1.10-4.20). Missed injuries occurred in 15% of patients. A unique finding was the increased odds of missed injury with nonsurgeon TTLs. Further research should be undertaken to explore this relationship, elucidate potential causes, and propose interventions to narrow this discrepancy between TTL provider types. Therapeutic study, level IV. Prognostic and epidemiologic study, level III.

Preparing nurse leaders for 2020.
Huston, Carol
2008-11-01
This article highlights eight leadership competencies likely to be an essential part of the nurse leader's repertoire in 2020. Planning for the future is difficult, even when environments are relatively static. When environments are dynamic, the challenges multiply exponentially. Unfortunately, few environments have been more unpredictable in the 21st century than health care. The healthcare system is in chaos, as is much of the business world. It is critical then that contemporary nursing and healthcare leaders identify skill sets that will be needed by nurse leaders in 2020 and begin now to create the educational models and management development programs necessary to assure these skills are present. Essential nurse leader competencies for 2020 include: (i) A global perspective or mindset regarding healthcare and professional nursing issues. (ii) Technology skills which facilitate mobility and portability of relationships, interactions, and operational processes. (iii) Expert decision-making skills rooted in empirical science. (iv) The ability to create organization cultures that permeate quality healthcare and patient/worker safety. (v) Understanding and appropriately intervening in political processes. (vi) Highly developed collaborative and team building skills. (vii) The ability to balance authenticity and performance expectations. (viii) Being able to envision and proactively adapt to a healthcare system characterized by rapid change and chaos. Nursing education programmes and healthcare organizations must be begin now to prepare nurses to be effective leaders in 2020. This will require the formal education and training that are a part of most management development programmes as well as a development of appropriate attitudes through social learning. Proactive succession planning will also be key to having nurse leaders who can respond effectively to the new challenges and opportunities that will be presented to them in 2020.

Individual deals within teams: Investigating the role of relative i-deals for employee performance.
Vidyarthi, Prajya R; Singh, Satvir; Erdogan, Berrin; Chaudhry, Anjali; Posthuma, Richard; Anand, Smriti
2016-11-01
The authors extend i-deals theory to an individual-within-a-team context. Drawing upon social comparison theory, they contend that individuals will react to their own i-deals within the context of group members' i-deals. Therefore, they examine the role of relative i-deals (an individual's i-deals relative to the team's average) in relation to employee performance. Furthermore, integrating social comparison theory with social identity theory the authors assert that the behavioral outcomes of relative i-deals are influenced by the team's social and structural attributes of team orientation and task interdependence. Finally, they contend that the perceptions of one's relative standing with the leader, or leader-member exchange social comparison (LMXSC), mediate the i-deals-outcome relationship in groups with low team orientation and task interdependence. Results of multilevel modeling using time-lagged data from 321 employees nested in 46 teams demonstrated that the positive relationship between relative i-deals and employee performance was stronger in groups with low team orientation and task interdependence, and the mediation effect of LMXSC was stronger in teams with low rather than high team orientation.

The purpose of this paper is to clarify how leadership is able to improve team effectiveness, by means of its influence on group processes (i.e., increasing group development) and on the group task (i.e., decreasing task uncertainty). Four hundred and eight members of 107 teams in a German research and development (R&D) organization completed a web-based survey; they provided measures of transformational leadership, group development, 2 aspects of task uncertainty, task interdependence, and team effectiveness. In 54 of these teams, the leaders answered a web-based survey on team effectiveness. We tested the model with the data from team members, using structural equations modeling. Group development and a task uncertainty measurement that refers to unstable demands from outside the team partially mediate the effect of transformational leadership on team effectiveness in R&D organizations ( p < 0.05). Although transformational leaders reduce unclarity of goals ( p < 0.05), this seems not to contribute to team effectiveness. The data provided by the leaders was used to assess common source bias, which did not affect the interpretability of the results. Limitations include cross-sectional data and a lower than expected variance of task uncertainty across different job types. This paper contributes to understanding how knowledge worker teams deal effectively with task uncertainty and confirms the importance of group development in this context. This is the first study to examine the effects of transformational leadership and team processes on team effectiveness considering the task characteristics uncertainty and interdependence.

Inhalant allergens from cockroaches are an important cause of asthma to millions of individuals worldwide. Here we report for the first time the structures of two major cockroach allergens, Bla g 4 and Per a 4, that adopt a typical lipocalin fold but with distinct structural features as compared with other known lipocalin allergens. Both Bla g 4 and Per a 4 contain two long-range disulfide bonds linking the N and C termini to a beta-barrel. The C-terminal helix of Bla g 4 is bent and greatly extended toward the N terminus. Bla g 4 is found to be amore » monomer, whereas Per a 4 exists as a dimer in solution with a novel dimeric interface involving residues from loops at the top and bottom of the beta-barrel. Putative ligand binding sites of both allergens are determined by docking of the juvenile hormone III inside the beta-barrel and found to interact with the ligand using non-conserved residues. Bla g 4 and Per a 4 are found to be cross-reactive in sera IgE binding, at least in the Singaporean Chinese population tested. A major IgE binding epitope unique to Per a 4 is found on the loops at the bottom of the beta-barrel that may aid the development of hypoallergens for immunotherapy.« less

Teams and teamwork at NASA Langley Research Center

Dickinson, Terry L.
1994-01-01
The recent reorganization and shift to managing total quality at the NASA Langley Research Center (LaRC) has placed an increasing emphasis on teams and teamwork in accomplishing day-to-day work activities and long-term projects. The purpose of this research was to review the nature of teams and teamwork at LaRC. Models of team performance and teamwork guided the gathering of information. Current and former team members served as participants; their collective experience reflected membership in over 200 teams at LaRC. The participants responded to a survey of open-ended questions which assessed various aspects of teams and teamwork. The participants also met in a workshop to clarify and elaborate on their responses. The work accomplished by the teams ranged from high-level managerial decision making (e.g., developing plans for LaRC reorganization) to creating scientific proposals (e.g., describing spaceflight projects to be designed, sold, and built). Teams typically had nine members who remained together for six months. Member turnover was around 20 percent; this turnover was attributed to heavy loads of other work assignments and little formal recognition and reward for team membership. Team members usually shared a common and valued goal, but there was not a clear standard (except delivery of a document) for knowing when the goal was achieved. However, members viewed their teams as successful. A major factor in team success was the setting of explicit a priori rules for communication. Task interdependencies between members were not complex (e.g., sharing of meeting notes and ideas about issues), except between members of scientific teams (i.e., reliance on the expertise of others). Thus, coordination of activities usually involved scheduling and attendance of team meetings. The team leader was designated by the team's sponsor. This leader usually shared power and responsibilities with other members, such that team members established their own operating

To estimate the prevalence of burnout and the perception of teamwork in Primary Care teams from Barcelona. Multicenter cross-sectional. Primary Health Care Teams from Barcelona. Institut Català de la Salut. All permanent employees or temporary professionals of all categories from 51 teams (N=2398). A total of 879 responses (36.7%) were obtained. The Maslach Burnout Inventory questionnaire, with 3 dimensions, was sent by emotional exhaustion (AE), depersonalization (DP), and personal accomplishment (RP). Burnout is considered present when two or more dimensions scored high marks. Perception of teamwork and evaluation of leaders was evaluated using an ad hoc questionnaire. The prevalence of burnout was17.2% (two or more dimensions affected), and 46.2% had at least one of the three dimensions with a high level. A high level of AE was found in 38.2%, of DP in 23.8%, and 7.7% had low RP. Almost half (49.2%) believe that teamwork is encouraged in their workplace. Social workers overall, have a higher average of dimensions affected at a high level, followed by administrative personnel, dentists, doctors and nurses (p<0.001). Permanent staff have a greater degree of emotional exhaustion (p<0.002). Those who rated their leaders worst and least rated teamwork had more emotional exhaustion, depersonalization and higher level of burnout in general (p<0.001). The level of burnout among professionals is considerable, with differences existing between occupational categories. Teamwork and appreciating their leaders protect from burnout.

Leader development transformation in the Army Nurse Corps.
Funari, Tamara S; Ford, Kathleen; Schoneboom, Bruce A
2011-01-01
The Army Nurse (AN) Corps is undergoing a historic transformation. Under the leadership of its Chief, MG Patricia Horoho, the Corps developed and implemented the AN Campaign Plan to insure that the Corps has the right capability and capacity to meet the current and future needs of the US Army. This article describes the work conducted by the AN Corps Leadership Imperative Action Team (Leader IAT) to develop full-spectrum leaders for the future. The mission of the Leader IAT is derived from both the AN Campaign plan as well as the operational objectives defined in the AN balanced scorecard. As a result of the analysis conducted during preparation of the AN Campaign Plan, several key gaps were identified regarding the Army Nurse Corps' ability to match leadership talents with the diverse demands of current missions, as well as its adaptability and flexibility to be prepared for unknown future missions. This article also introduces the Leadership Capability Map and other initiatives implemented to ensure the development of full-spectrum leaders who will be effective in the future military healthcare environment.

Individual performance and leader's laterality in interactive contests.
Mukherjee, Satyam
2017-05-01
Left-handedness is known to provide an intrinsic and tactical advantage at top level in many sports involving interactive contests. Again, most of the renowned leaders of the world are known to have been left-handed. Leadership plays an important role in politics, sports and mentorship. In this paper we show that Cricket captains who bat left-handed have a strategic advantage over the right-handed captains in One Day International (ODI) and Test matches. The present study involving 46 left-handed captains and 148 right-handed captains in ODI matches, reveal a strong relation between leader's laterality and team member performance, demonstrating the critical importance of left-handedness and successful leadership. The odds for superior batting performance in an ODI match under left-handed captains are 89% higher than the odds under right-handed captains. Our study shows that left-handed captains are more successful in extracting superior performance from the batsmen and bowlers in ODI and Test matches; perhaps indicating left-handed leaders are better motivators as leaders when compared to right-handed captains.

ABSTRACT Mycobacterium abscessus pulmonary infections are treated with a macrolide (clarithromycin or azithromycin), an aminoglycoside (amikacin), and a β-lactam (cefoxitin or imipenem). The triple combination is used without any β-lactamase inhibitor, even though M. abscessus produces the broad-spectrum β-lactamase BlaMab. We determine whether inhibition of BlaMab by avibactam improves the activity of imipenem against M. abscessus. The bactericidal activity of drug combinations was assayed in broth and in human macrophages. The in vivo efficacy of the drugs was tested by monitoring the survival of infected zebrafish embryos. The level of BlaMab production in broth and in macrophages was compared by quantitative reverse transcription-PCR and Western blotting. The triple combination of imipenem (8 or 32 μg/ml), amikacin (32 μg/ml), and avibactam (4 μg/ml) was bactericidal in broth (<0.1% survival), with 3.2- and 4.3-log10 reductions in the number of CFU being achieved at 72 h when imipenem was used at 8 and 32 μg/ml, respectively. The triple combination achieved significant intracellular killing, with the bacterial survival rates being 54% and 7% with the low (8 μg/ml) and high (32 μg/ml) dosages of imipenem, respectively. In vivo inhibition of BlaMab by avibactam improved the survival of zebrafish embryos treated with imipenem. Expression of the gene encoding BlaMab was induced (20-fold) in the infected macrophages. Inhibition of BlaMab by avibactam improved the efficacy of imipenem against M. abscessus in vitro, in macrophages, and in zebrafish embryos, indicating that this β-lactamase inhibitor should be clinically evaluated.

Mycobacterium abscessus pulmonary infections are treated with a macrolide (clarithromycin or azithromycin), an aminoglycoside (amikacin), and a β-lactam (cefoxitin or imipenem). The triple combination is used without any β-lactamase inhibitor, even though M abscessus produces the broad-spectrum β-lactamase Bla Mab We determine whether inhibition of Bla Mab by avibactam improves the activity of imipenem against M. abscessus The bactericidal activity of drug combinations was assayed in broth and in human macrophages. The in vivo efficacy of the drugs was tested by monitoring the survival of infected zebrafish embryos. The level of Bla Mab production in broth and in macrophages was compared by quantitative reverse transcription-PCR and Western blotting. The triple combination of imipenem (8 or 32 μg/ml), amikacin (32 μg/ml), and avibactam (4 μg/ml) was bactericidal in broth (<0.1% survival), with 3.2- and 4.3-log 10 reductions in the number of CFU being achieved at 72 h when imipenem was used at 8 and 32 μg/ml, respectively. The triple combination achieved significant intracellular killing, with the bacterial survival rates being 54% and 7% with the low (8 μg/ml) and high (32 μg/ml) dosages of imipenem, respectively. In vivo inhibition of Bla Mab by avibactam improved the survival of zebrafish embryos treated with imipenem. Expression of the gene encoding Bla Mab was induced (20-fold) in the infected macrophages. Inhibition of Bla Mab by avibactam improved the efficacy of imipenem against M. abscessus in vitro , in macrophages, and in zebrafish embryos, indicating that this β-lactamase inhibitor should be clinically evaluated. The in vitro evaluation of imipenem may underestimate the impact of Bla Mab , since the production of the β-lactamase is inducible in macrophages. Copyright © 2017 American Society for Microbiology.

Becoming a nurse faculty leader: Taking risks by being willing to fail.
Pardue, Karen T; Young, Patricia K; Horton-Deutsch, Sara; Halstead, Judith; Pearsall, Catherine
2018-04-01
Higher education is undergoing rapid transformation requiring nurse faculty leaders to engage in risk taking. Consequently, what is known about the experience of taking risks? How do leaders decide what constitutes a risk worth taking? How do leaders who take risks tolerate failure? The purpose of this study was to explicate the leadership practices of risk taking in nurse faculty leaders. Interpretive phenomenology was used to explore the experience of risk taking among 15 self-identified nurse faculty leaders. Unstructured audio recorded interviews were conducted in which participants described their experiences of taking risks. Transcribed interviews were analyzed by a research team to uncover themes in the narrative data. A theme, willingness to fail, and three subthemes, enacting a culture of experimentation, working hard for success, and learning from failure are reported. This study provides practical know-how and an evidence-base to support nurse academic leaders in the practice of risk taking during these challenging times in higher education. © 2018 Wiley Periodicals, Inc.

In response to global concerns over the spread of the New Delhi metallo-β-lactamase gene 1, bla(NDM-1), a monthly surveillance program was initiated in September 2010. All carbapenem-resistant Gram-negative strains forwarded to our facility are screened for this gene. To date, 321 carbapenem-resistant isolates, encompassing 11 bacterial species, have been tested. In February 2011, two strains of Providencia stuartii, submitted from a military hospital in Afghanistan, tested positive for bla(NDM-1). Both strains were identical by pulsed-field gel electrophoresis (PFGE). bla(NDM-1) was carried on a large plasmid, pMR0211, which was sequenced by emulsion PCR and pyrosequencing. pMR0211 is 178,277 bp in size and belongs to incompatibility group A/C. The plasmid consists of a backbone with considerable homology to pAR060302 from Escherichia coli, and it retains many of the antibiotic resistance genes associated with it. The plasmid also shares common elements with the pNDM-HK plasmid, including bla(NDM-1), armA, and sul1. However, gene orientation is reversed, and a 3-kb fragment from this region is absent from pMR0211. pMR0211 also contains additional genes, including the aminoglycoside-modifying enzyme loci aadA and aac(6'), the quinolone resistance gene qnrA, a gene with highest homology to a U32 family peptidase from Shewanella amazonensis, and the bla(OXA-10) gene. The finding of this gene in an intrinsically colistin-resistant species such as Providencia stuartii is especially worrisome, as it renders the organism resistant to nearly every available antibiotic. The presence of multiple insertion sequences and transposons flanking the region containing the bla(NDM-1) gene further highlights the potential mobility associated with this gene.

Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae isolates have been increasingly reported worldwide, and therapeutic options to treat infections caused by these organisms are limited. We evaluated the activity of ceftazidime-avibactam and comparators against 456 Enterobacteriaceae isolates carrying bla KPC collected from 79 U.S. hospitals during 2012 to 2015. Overall, ceftazidime-avibactam (MIC 50/90 , 0.5/2 μg/ml; 99.3% susceptible) and tigecycline (MIC 50/90 , 0.5/1 μg/ml; 98.9% susceptible at ≤2 μg/ml) were the most active agents. Only 80.5% and 59.0% of isolates were susceptible to colistin and amikacin, respectively. All three isolates (0.7%) displaying resistance to ceftazidime-avibactam ( K. pneumoniae ; MICs, ≥16 μg/ml) were evaluated using whole-genome sequencing analysis and relative quantification of expression levels of porins and efflux pump. Two isolates carried metallo-β-lactamase genes, bla NDM-1 or bla VIM-4 , among other β-lactam resistance mechanisms, and one displayed a premature stop codon in ompK35 and decreased expression of ompK36 Ceftazidime-avibactam was active against 100.0 and 99.3% of isolates carrying bla KPC-3 ( n = 221) and bla KPC-2 ( n = 145), respectively. Isolates carrying bla KPC were more commonly recovered from pneumonia ( n = 155), urinary tract ( n = 93), and skin/soft tissue ( n = 74) infections. Ceftazidime-avibactam (97.8 to 100.0% susceptible) was consistently active against isolates from all infection sites. K. pneumoniae (83.3% of the collection) susceptibility rates were 99.2% for ceftazidime-avibactam, 98.9% for tigecycline, and 80.1% for colistin. Ceftazidime-avibactam susceptibility did not vary substantially when comparing isolates from intensive care unit (ICU) patients to those from non-ICU patients. Ceftazidime-avibactam was active against this large collection of isolates carrying bla KPC and represents a valuable addition to the armamentarium currently available for the

Implementation of a team-based learning course: Work required and perceptions of the teaching team.
Morris, Jenny
2016-11-01
Team-based learning was selected as a strategy to help engage pre-registration undergraduate nursing students in a second-year evidence-informed decision making course. To detail the preparatory work required to deliver a team-based learning course; and to explore the perceptions of the teaching team of their first experience using team-based learning. Descriptive evaluation. Information was extracted from a checklist and process document developed by the course leader to document the work required prior to and during implementation. Members of the teaching team were interviewed by a research assistant at the end of the course using a structured interview schedule to explore perceptions of first time implementation. There were nine months between the time the decision was made to use team-based learning and the first day of the course. Approximately 60days were needed to reconfigure the course for team-based learning delivery, develop the knowledge and expertise of the teaching team, and develop and review the resources required for the students and the teaching team. This reduced to around 12days for the subsequent delivery. Interview data indicated that the teaching team were positive about team-based learning, felt prepared for the course delivery and did not identify any major problems during this first implementation. Implementation of team-based learning required time and effort to prepare the course materials and the teaching team. The teaching team felt well prepared, were positive about using team-based learning and did not identify any major difficulties. Crown Copyright © 2016. Published by Elsevier Ltd.

Occupational therapists in the interdisciplinary team setting.
Reed, S M
1984-01-01
The interdisciplinary team approach to patient care provides an answer to the fragmentation and confusion patients feel when dealing with our complex healthcare system. Even though the team approach has been in use for the past two decades, implementation of a successful team is very difficult and rarely sustained over a significant period of time. This is especially true in general hospitals and in physical rehabilitation programs that spring from general hospitals where the physician and the nurse are the traditional care group. Occupational therapists, as they establish roles on interdisciplinary teams as staff members and team leaders, will require a knowledge of what makes a team function effectively. They can use this knowledge to evaluate the status of their own team and contribute to changes that will insure its long-term success. Six key issues should be addressed during the planning stage of any new healthcare team to insure its continued viability. These issues are: program philosophy, client focus, role clarification, collaboration and information sharing, policies and procedures, and staff supportiveness.

Working with sports organizations and teams.
McDuff, David R; Garvin, Michelle
2016-12-01
Athletes and coaches at all competitive levels will utilize sports performance and psychiatric services at very high rates if the services are offered on-site and free of charge and are broad in scope and culturally sensitive. Services should be available throughout the team year and cover areas such as team building, mental preparation, stress control, substance prevention, sleep and energy regulation, injury recovery, crisis intervention, and mental disorder treatment. The staff offering these services should be diverse by gender, profession, and culture, and the fees should be paid by the organization. When these services are endorsed by the team's leaders and integrated with the athletic training/medical/player development staff, their utilization will grow quickly and lead to positive outcomes individually and collectively.

Dissemination of resistance to carbapenems among Enterobacteriaceae through plasmids is an increasingly important concern in health care worldwide. Here we report the first description of an IncX3 plasmid carrying the blaKPC-3 gene in a strain of Serratia marcescens isolated from a kidney-liver transplanted patient at the transplantation centre ISMETT (Istituto Mediterraneo per i Trapianti e Terapie ad Alta Specializzazione, Palermo, Italy). To localize the transposable element containing the resistance-associated gene Next-Generation Sequencing of the bacterial DNA was performed. S. marcescens was positive for blaKPC-3 and blaSHV-11 genes. The molecular analysis demonstrated that the blaKPC-3 gene of this bacterial strain was located in one copy of the Tn-3-like element Tn4401-a carried in a plasmid that is 53 392 bp in size and showed the typical IncX3 scaffold. Our data demonstrated the presence of a new blaKPC-3 harbouring the IncX3 plasmid in S. marcescens. The possible dissemination among Enterobacteriaceae of this type of plasmid should be monitored and evaluated in terms of clinical risk.

Superb leaders have very different ways of directing a team, a division, or a company. Some are subdued and analytical; others are charismatic and go with their gut. And different situations call for different types of leadership. Most mergers need a sensitive negotiator at the helm, whereas many turnarounds require a more forceful kind of authority. Psychologist and noted author Daniel Goleman has found, however, that effective leaders are alike in one crucial way: they all have a high degree of what has come to be known as emotional intelligence. In fact, Goleman's research at nearly 200 large, global companies revealed that emotional intelligence--especially at the highest levels of a company--is the sine qua non for leadership. Without it, a person can have first-class training, an incisive mind, and an endless supply of good ideas, but he still won't make a great leader. The components of emotional intelligence--self-awareness, self-regulation, motivation, empathy, and social skill--can sound unbusinesslike. But exhibiting emotional intelligence at the workplace does not mean simply controlling your anger or getting along with people. Rather, it means understanding your own and other people's emotional makeup well enough to move people in the direction of accomplishing your company's goals. In this article, the author discusses each component of emotional intelligence and shows through examples how to recognize it in potential leaders, how and why it leads to measurable business results, and how it can be learned. It takes time and, most of all, commitment. But the benefits that come from having a well-developed emotional intelligence, both for the individual and the organization, make it worth the effort.

Objective(s) Extended-spectrum beta-lactamase (ESBL) producing bacteria have an important role in nosocomial infections. Due to the limited availability of information about the molecular epidemiology of ESBL producing bacteria in Mashhad, we decided to investigate about TEM, CTX and SHV ESBLs among urinary Escherichia coli isolates in Mashhad, a city in northeast Iran. Materials and Methods One hundred and eleven clinical isolates of E. coli were diagnosed from hospitalized patients in 2009. After performing antibiogram and phenotypic confirmation test, polymerase chain reaction (PCR) was performed by blaTEM, blaSHV and blaCTX primers and restriction digestion was carried out using PstI and TaqI (Fermentas-Lithuania) for confirmation. Results ESBL producers of E. coli isolates were 33.3%. Among 37 ESBL-producing isolates, 35 (94.6%), 21 (56.8%) and 5 (13.5%) were shown to have blaCTX, blaTEM and blaSHV, genes respectively. Co-resistance to non-beta lactam antibiotics was observed more with ESBL producers (P < 0.05). Conclusion The results showed that the studied ESBL genes are found with high prevalence and among them blaCTX is more widespread in urine E. coli isolates in Mashhad. PMID:23493415

Background Plasmid mediated antimicrobial resistance in the Enterobacteriaceae is a global problem. The rise of CTX-M class extended spectrum beta lactamases (ESBLs) has been well documented in industrialized countries. Vietnam is representative of a typical transitional middle income country where the spectrum of infectious diseases combined with the spread of drug resistance is shifting and bringing new healthcare challenges. Methodology We collected hospital admission data from the pediatric population attending the hospital for tropical diseases in Ho Chi Minh City with Shigella infections. Organisms were cultured from all enrolled patients and subjected to antimicrobial susceptibility testing. Those that were ESBL positive were subjected to further investigation. These investigations included PCR amplification for common ESBL genes, plasmid investigation, conjugation, microarray hybridization and DNA sequencing of a bla CTX–M encoding plasmid. Principal Findings We show that two different bla CTX-M genes are circulating in this bacterial population in this location. Sequence of one of the ESBL plasmids shows that rather than the gene being integrated into a preexisting MDR plasmid, the bla CTX-M gene is located on relatively simple conjugative plasmid. The sequenced plasmid (pEG356) carried the bla CTX-M-24 gene on an ISEcp1 element and demonstrated considerable sequence homology with other IncFI plasmids. Significance The rapid dissemination, spread of antimicrobial resistance and changing population of Shigella spp. concurrent with economic growth are pertinent to many other countries undergoing similar development. Third generation cephalosporins are commonly used empiric antibiotics in Ho Chi Minh City. We recommend that these agents should not be considered for therapy of dysentery in this setting.

In order to study the clonal relationship and blaKPC gene detection in clinical isolates of Klebsiella pneumoniae resistant to carbapenems, we analyzed 22 clinical isolates of K. pneumoniae with resistance to imipenem and/ or meropenem, isolated in the laboratory of bacteriology at the University Hospital "Antonio Patricio de Alcalá" (HUAPA) from the Cumana city, Sucre state, Venezuela, for a period of five consecutive years. Susceptibility to different antimicrobials was determined, and the presence of carbapenemases was detected by modified Hodge method, phenyl boronic acid synergy and combination discs. blaKPC gene detection was conducted by polymerase chain reaction and the clonal relationship was determined by pulsed field electrophoresis. High rates of antimicrobial resistance were found, five strains were negative, at least one phenotypic method, and all carried the blaKPC gene. Clonal spread was observed only in the intensive care unit (ICU), while in other services, polyclonality was found. We concluded that blaKPC gene is present in K. pneumoniae strains resistant to carbapenems isolated in the HUAPA and clonal spread it was only in the ICU.

Peer mentored teams to support undergraduate group work in higher education
NASA Astrophysics Data System (ADS)
Cinderey, Lynn Elizabeth
This research starts with a set of practical research questions to investigate a problem which occurs in some computing undergraduate modules that use group work as part of the learning and assessment strategy. In this study final year students with experience in information systems project work and trained in team processes met with small groups of first year computing students with the aim of turning the first year project group into a team. This study seeks to explore the experience of the final year students as they take on the role of peer tutor looking at the problems they perceive within the first year teams and the skills and knowledge they use to help them. The study includes the recruitment and training of final year students (n=9) and allocation to first year teams. The final year students acted as co-researchers and team leaders in L4 Information Systems project work and recorded their thoughts and observations in a diary during the first semester of 2008/9 academic year. Diary data was supplemented by interview data from a sample of final year students (n=4). The sample was selected based on the richness of the data provided in the diaries and the number of meetings held with their teams. Rich data and thick descriptions were essential for a phenomenological examination of the experience of the final year students. A number of findings emerged. A critical approach to analysis revealed ongoing conflicts occurred across cultural divides within the first year teams that final year leaders did not articulate or appear fully aware of. This had important implications for individual team members. Other findings which relate to issues of changing levels of motivation in the teams over the ten weeks, roles adopted by the leaders, ability to systematize the project or team processes and the ability to reflect on unsuccessful strategies also had implications for peer mentoring training and support. The picture that emerged from the data suggested that lack of

To examine the beliefs and attitudes of FPs and health care professionals (HCPs) regarding FPs' roles and responsibilities on interdisciplinary geriatric health care teams. Qualitative study using focus groups. Calgary Health Region. Seventeen FPs and 22 HCPs working on geriatric health care teams. Four 90-minute focus groups were conducted with FPs, followed by 2 additional 90-minute focus groups with HCPs. The FP focus groups discussed 4 vignettes of typical teamwork scenarios. Discussions were transcribed and the 4 researchers analyzed and coded themes and subthemes and developed the HCP focus group questions. These questions asked about HCPs' expectations of FPs on teams, experiences with FPs on teams, and perspectives on optimal roles on teams. Several meetings were held to determine themes and subthemes. Family physicians identified patient centredness, role delineation for team members, team dynamics, and team structure as critical to team success. Both FPs and HCPs had a continuum of beliefs about the role FPs should play on teams, including whether FPs should be autonomous or collaborative decision makers, the extent to which FPs should work within or outside teams, whether FPs should be leaders or simply members of teams, and the level of responsibility implied or explicit in their roles. Comments from FPs and HCPs identified intraprofessional and interprofessional tensions that could affect team practice and impede the development of high-functioning teams. It will be important, as primary care reform continues, to help FPs and HCPs learn how to work together effectively on teams so that patients receive the best possible care.

This paper presents empirical research into the relationship between leader-follower value congruence in social responsibility and the level of ethical satisfaction for employees in the workplace. 163 dyads were analyzed, each consisting of a team leader and an employee working at a large manufacturing company in South Korea. Following current methodological recommendations for congruence research, polynomial regression and response surface modeling methodologies were used to determine the effects of value congruence. Results indicate that leader-follower value congruence in social responsibility was positively related to the ethical satisfaction of employees. Furthermore, employees' ethical satisfaction was stronger when aligned with a leader with high social responsibility. The theoretical and practical implications are discussed.

Purpose The organisational level and leadership development are crucial elements in advancing patient safety, because patient safety weaknesses are often caused by system failures. However, little is known about how frontline leader and director teams can be supported to develop patient safety practices. The purpose of this study is to describe the patient safety development process carried out by nursing leaders and directors. The research questions were: how the chosen development areas progressed in six months' time and how nursing leaders view the participatory development process. Design/methodology/approach Participatory action research was used to engage frontline nursing leaders and directors into developing patient safety practices. Semi-structured group interviews ( N = 10) were used in data collection at the end of a six-month action cycle, and data were analysed using content analysis. Findings The participatory development process enhanced collaboration and gave leaders insights into patient safety as a part of the hospital system and their role in advancing it. The chosen development areas advanced to different extents, with the greatest improvements in those areas with simple guidelines to follow and in which the leaders were most participative. The features of high-reliability organisation were moderately identified in the nursing leaders' actions and views. For example, acting as a change agent to implement patient safety practices was challenging. Participatory methods can be used to support leaders into advancing patient safety. However, it is important that the participants are familiar with the method, and there are enough facilitators to steer development processes. Originality/value Research brings more knowledge of how leaders can increase their effectiveness in advancing patient safety and promoting high-reliability organisation features in the healthcare organisation.

A unique undergraduate team that spans five different engineering disciplines, chemistry, biology, and mathematics was formed. The team was formed to promote cross-disciplinary learning, to improve retention, and to prepare the students for the kind of problems they will face in their careers. This paper describes the variety of activities used over 2 years to tie the team together, as well as afford opportunities to develop team-building skills. The activities described highlight the critical elements of a faculty leader whose own work is interdisciplinary, correct balance of disciplines in the team, and sufficient time for team development. The use of external feedback was essential for all activities. Clearly defined goals and hard deadlines were critical for the completion of individual activities, as well as developing a healthy team environment. Although the student cohort has learned from the activities, more time is needed to assess whether the students have become a fully efficient team. Furthermore, an additional cohort would be needed to assess whether the approach was able to assist with student's interest in STEM and their desire to help other people.

The extended spectrum β-lactamase (ESBL)-producing Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) are the major pathogens causing pneumonia and have a significant impact on the clinical course. Limited data exist on molecular characterization of ESBL-producing E. coli and K. pneumoniae that cause pneumonia. The aim of this study was to investigate the comprehensive multilevel characteristics of E. coli and K. pneumoniae causing pneumonia in China for the first time. E. coli (17) and K. pneumoniae (21) isolates responsible for pneumonia were isolated from 1270 specimens collected in a prospective multi-center study in eight teaching hospitals in China from June to December in 2007. The susceptibilities, ESBL confirmation, sequence typing, blaCTX-M and blaSHV genes, their genetic environment and plasmid Inc/rep types were determined. Sixteen E. coli (94.1%) and eleven K. pneumoniae (52.4%) isolates were ESBL producers. About 77.8% and 66.7% of them were resistance to ciprofloxacin and levofloxacin, and 100% were susceptible to imipenem. The most prevalent ESBL gene was CTX-M-14, followed by SHV-2, CTX-M-15, CTX-M-3, CTX-M-65, SHV-12, SHV-26 and SHV-28. SHV-1 and SHV-11 were also detected and coexisted with blaCTX-Ms in five strains, and three strains contained only SHV-1. All CTX-M-14 were detected ISEcp1 upstream and nine were found IS903 downstream and the majority of them (64.3%) were carried by IncF plasmids. All blaSHV were flanked by recF and deoR, located on IncF, IncN, IncX and IncH plasmids. Two SHV-2, one SHV-1 and the only SHV-28 were further preceded by IS26. Genes lacY and lacZ were detected at further upstream of two blaSHV-1. The K. pneumoniae carrying SHV-28 was susceptible to β-lactams, and no mutations or deletions in gene or promoter sequences were identified to account for susceptibility. Multilocus sequence typing experiments showed the ESBL-producing strains were genetically diverse. The rate of occurrence of blaESBL in E

Bacteria that produce Klebsiella pneumoniae carbapenemases (KPCs) are resistant to broad-spectrum β-lactam antibiotics. The objective of this study was to phenotypically and genotypically characterize the antibiotic susceptibility to carbapenems of 297 isolates recovered from clinical samples obtained from inpatients at 16 hospitals in São Luis (Maranhão, Brazil). The study was conducted using phenotypic tests and molecular methods, including polymerase chain reaction (PCR), sequencing and enterobacterial repetitive intergenic consensus (ERIC)-PCR. The nonparametric chi-square test of independence was used to evaluate the associations between the bacterial bla KPC gene and the modified Hodge test, and the chi-square adherence test was used to assess the frequency of carbapenemases and their association with the bla KPC gene. The most frequently isolated species were Acinetobacter baumannii (n = 128; 43.0%), K. pneumoniae (n = 75; 25.2%), and Pseudomonas aeruginosa (n = 42; 14.1%). Susceptibility assays showed that polymixin B was active against 89.3% of the bacterial isolates. The Acinetobacter spp. and K. pneumoniae strains were susceptible to amikacin and tigecycline, and Pseudomonas spp. were sensitive to gentamicin and amikacin. Among the 297 isolates, 100 (33.7%) were positive for the bla KPC gene, including non-fermentative bacteria (A. baumannii) and Enterobacteriaceae species. Among the isolates positive for the bla KPC gene, K. pneumoniae isolates had the highest positivity rate of 60.0%. The bla KPC gene variants detected included KPC-2, which was found in all isolates belonging to species of the Enterobacteriaceae family. KPC-2 and KPC-3 were observed in A. baumannii isolates. Importantly, the bla KPC gene was also detected in three Raoultella isolates and one isolate of the Pantoea genus. ERIC-PCR patterns showed a high level of genetic diversity among the bacterial isolates; it was capable of distinguishing 34 clones among 100 strains

Multicultural team leaders under the conditions of globalisation process must understand that acquiring cultural awareness and diversity management skills is one of the premises for gaining competitive advantage and satisfying the employeeś need for social cohesion. The concept presented in this paper goes beyond standard understanding of what cultural diversity management means, as it is not perceived as a set of activities that a business as a whole should be responsible for, but encourage every leader to take responsibility for its own awareness firstly. After understanding that cross-cultural competence is a lifelong learning process it is possible to start recognising one’s own cultural mindset before attempting to recognise those of people from other cultures. At this point it is a right time to spread the experience amongst other team members or associates.

Narcissists often pursue leadership and are selected for leadership positions by others. At the same time, they act in their own best interest, putting the needs and interests of others at risk. While theoretical arguments clearly link narcissism and leadership, the question whether leader narcissism is good or bad for organizations and their members remains unanswered. Narcissism seems to have two sides, a bright and a dark one. This systematic literature review seeks to contribute to the ongoing academic discussion about the positive or negative impact of leader narcissism in organizations. Forty-five original research articles were categorized according to outcomes at three levels of analysis: the dyadic level (focusing on leader-follower relationships), the team level (focusing on work teams and small groups), and the organizational level. On this basis, we first summarized the current state of knowledge about the impact that leader narcissism has on outcomes at different levels of analysis. Next, we revealed similarities and contradictions between research findings within and across levels of analysis, highlighting persistent inconsistencies concerning the question whether leader narcissism has positive or negative consequences. Finally, we outlined theoretical and methodological implications for future studies of leader narcissism. This multi-level perspective ascertains a new, systematic view of leader narcissism and its consequences for organizations and their stakeholders. The article demonstrates the need for future research in the field of leader narcissism and opens up new avenues for inquiry. PMID:28579967

In 2012 and 2014 the Norwegian monitoring programme for antimicrobial resistance in the veterinary and food production sectors (NORM-VET) showed that 124 of a total of 406 samples (31%) of Norwegian retail chicken meat were contaminated with extended-spectrum cephalosporin-resistant Escherichia coli. The aim of this study was to compare selected cephalosporin-resistant E. coli from humans and poultry to determine their genetic relatedness based on whole genome sequencing (WGS). Escherichia coli representing three prevalent cephalosporin-resistant multi-locus sequence types (STs) isolated from poultry (n=17) were selected from the NORM-VET strain collections. All strains carried an IncK plasmid with a bla CMY-2 gene. Clinical E. coli isolates (n=284) with AmpC-mediated resistance were collected at Norwegian microbiology laboratories from 2010 to 2014. PCR screening showed that 29 of the clinical isolates harboured both IncK and bla CMY-2 . All IncK/bla CMY-2 -positive isolates were analysed with WGS-based bioinformatics tools. Analysis of single nucleotide polymorphisms (SNP) in 2.5 Mbp of shared genome sequences showed close relationship, with fewer than 15 SNP differences between five clinical isolates from urinary tract infections (UTIs) and the ST38 isolates from poultry. Furthermore, all of the 29 clinical isolates harboured IncK/bla CMY-2 plasmid variants highly similar to the IncK/bla CMY-2 plasmid present in the poultry isolates. Our results provide support for the hypothesis that clonal transfer of cephalosporin-resistant E. coli from chicken meat to humans may occur, and may cause difficult-to-treat infections. Furthermore, these E. coli can be a source of AmpC-resistance plasmids for opportunistic pathogens in the human microbiota.

Resistance to β-lactam/β-lactamase inhibitors in enterobacteria is a growing problem that has not been intensively studied in Argentina. In the present work, 54/843 enterobacteria collected in a teaching hospital of Buenos Aires city were ampicillin-sulbactam-resistant isolates remaining susceptible to second- and third-generation cephalosporins. The enzymatic mechanisms present in the isolates, which were also amoxicillin-clavulanic acid (AMC)-resistant (18/54) were herein analyzed. Sequencing revealed two different variants of blaTEM-1, being blaTEM-1b the most frequently detected allelle (10 Escherichia coli, 3 Klebsiella pneumoniae, 2 Proteus mirabilis and 1 Raoultella terrigena) followed by blaTEM-1a (1 K. pneumoniae). Amoxicillin-clavulanate resistance seems to be mainly associated with TEM-1 overproduction (mostly in E. coli) or co-expressed with OXA-2-like and/or SHV β-lactamases (K. pneumoniae and P. mirabilis). A new blaTEM variant (TEM-163) was described in an E. coli strain having an AMC MIC value of 16/8μg/ml. TEM-163 contains Arg275Gln and His289Leu amino acid substitutions. On the basis of the high specific activity and low IC50 for clavulanic acid observed, the resistance pattern seems to be due to overproduction of the new variant of broad spectrum β-lactamase rather than to an inhibitor-resistant TEM (IRT)-like behavior.

Watkins, Michael D

Most leaders don't have the luxury of building their teams from scratch. Instead they're put in charge of an existing group, and they need guidance on the best way to take over and improve performance. Watkins, an expert on transitions, suggests a three-step approach: Assess. Act quickly to size up the personnel you've inherited, systematically gathering data from one-on-one chats, team meetings, and other sources. Reflect, too, on the business challenges you face, the kinds of people you want in various roles, and the degree to which they need to collaborate. Reshape. Adjust the makeup of the team by moving people to new positions, shifting their responsibilities, or replacing them. Make sure that everyone is aligned on goals and how to achieve them--you may need to change the team's stated direction. Consider also making changes in the way the team operates (reducing the frequency of meetings, for example, or creating new subteams). Then establish ground rules and processes to sustain desired behaviors, and revisit those periodically. Accelerate team development. Set your people up for some early wins. Initial successes will boost everyone's confidence and reinforce the value of your new operating model, thus paving the way for ongoing growth.

Most postsecondary institutions in the state of Alaska (USA) have a broad mission to serve diverse students, many of whom come from schools in rural villages that are accessible only by plane, boat, or snowmobile. The major research university, the University of Alaska in Fairbanks (UAF), serves a population whereby 40% are from groups recognized as underrepresented in the biomedical workforce. The purpose of this article is to describe the Building Infrastructure Leading to Diversity (BUILD)-supported program in the state of Alaska that seeks to engage students from rural areas with a culturally relevant approach that is centered on the One Health paradigm, integrating human, animal, and environmental health. The Biomedical Learning and Student Training (BLaST) program distinguished by broad themes that address recruitment, retention, and success of students in biomedical programs, especially for students from rural backgrounds. Targeted rural outreach emphasizes that biomedical research includes research on the integration of human, animal, and environmental health. This One Health perspective gives personal relevance and connection to biomedical research. This outreach is expected to benefit student recruitment, as well as foster family and community support for pursuit of college degrees. BLaST promotes integration of research into undergraduate curricula through curriculum development, and by creating a new class of instructors, laboratory research and teaching technicians, who provide research mentorship, course instruction, and comprehensive advising. Finally, BLaST facilitates early and sustained undergraduate research experiences in collaborations with graduate students and faculty. BLaST's approach is highly adapted to the Alaskan educational and physical environment, but components and concepts could be adapted to other rural areas as a means to engage students from rural backgrounds, who often have a closer relationship with the natural environment than

A new role for the ACNP: the rapid response team leader.
Morse, Kate J; Warshawsky, Deborah; Moore, Jacqueline M; Pecora, Denise C
2006-01-01
The implementation of a rapid response team or medical emergency team is 1 of the 6 initiatives of the Institute for Healthcare Improvement's 100,000 Lives Campaign with the goal to reduce the number of cardiopulmonary arrests outside the intensive care unit and inpatient mortality rates. The concept of RRT was pioneered in Australia and is now being implemented in many hospitals across the United States. This article reviews the current literature and describes the implementation of an RRT in a community hospital. The first-quarter data after implementation are described. The unique role of the acute care nurse practitioner in this hospital's model is described.

We describe lessons for safety from a synthesis of seven studies of teamwork, leadership and team training across a healthcare region. Two studies identified successes and challenges in a unit with embedded team training: a staff survey demonstrated a positive culture but a perceived need for greater senior presence; training improved actual emergency care, but wide variation in team performance remained. Analysis of multicenter simulation records showed that variation in patient safety and team efficiency correlated with their teamwork but not individual knowledge, skills or attitudes. Safe teams tended to declare the emergency earlier, hand over in a more structured way, and use closed-loop communication. Focused and directed communication was also associated with better patient-actor perception of care. Focus groups corroborated these findings, proposed that the capability and experience of the leader is more important than seniority, and identified teamwork and leadership issues that require further research. © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

Bacterial resistance occurs by spontaneous mutations or horizontal gene transfer mediated by mobile genetic elements, which represents a great concern. Resistance to β-lactam antibiotics is mainly due to the production of β-lactamases, and an important mechanism of fluoroquinolone resistance is the acquisition plasmid determinants. The aim of this study was to verify the presence of β-lactamase-encoding genes and plasmid-mediated quinolone resistance genes in different water samples obtained from São Paulo state, Brazil. A high level of these resistance genes was detected, being the bla SHV , bla GES , and qnr the most prevalent. Besides that, the bla NDM gene, which codify an important and hazardous metallo-β-lactamase, was detected.

The current emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis calls for novel treatment strategies. Recently, BlaC, the principal β-lactamase of Mycobacterium tuberculosis, was recognized as a potential therapeutic target. The combination of meropenem and clavulanic acid, which inhibits BlaC, was found to be effective against even extensively drug-resistant M. tuberculosis strains when tested in vitro. Yet there is significant concern that drug resistance against this combination will also emerge. To investigate the potential of BlaC to evolve variants resistant to clavulanic acid, we introduced substitutions at important amino acid residues of M. tuberculosis BlaC (R220, A244, S130, and T237). Whereas the substitutions clearly led to in vitro clavulanic acid resistance in enzymatic assays but at the expense of catalytic activity, transformation of variant BlaCs into an M. tuberculosis H37Rv background revealed that impaired inhibition of BlaC did not affect inhibition of growth in the presence of ampicillin and clavulanate. From these data we propose that resistance to β-lactam-β-lactamase inhibitor combinations will likely not arise from structural alteration of BlaC, therefore establishing confidence that this therapeutic modality can be part of a successful treatment regimen against M. tuberculosis.

This year, the University of Arizona is conducting its first two Leadership Workshops for Girl Scout adult leaders. These workshops are being supported by a five-year NASA Collaborative Agreement, Reaching for the Stars: NASA Science for Girl Scouts (www.seti.org/GirlScoutStars), through the SETI Institute in collaboration with the University of Arizona, Girl Scouts of the USA (GSUSA), the Girl Scouts of Northern California, the Astronomical Society of the Pacific, and Aries Scientific, Inc. These workshops are an outgrowth of Astronomy Camp for Girl Scout Leaders, a 14-year "Train the Trainer" program funded by NASA through the James Webb Space Telescope's Near Infrared Camera (NIRCam) education and outreach team. We are continuing our long-term relationship with all Girl Scout Councils to engage girls and young women not only in science and math education, but also in the astronomical and technological concepts relating to NASA's scientific mission. Our training aligns with the GSUSA Journey: It's Your Planet-Love It! and introduces participants to some of the activities that are being developed by the Girl Scout Stars team for GSUSA's new space science badges for all Girl Scout levels being developed as a part of Reaching for the Stars: NASA Science for Girl Scouts.The workshops include hands-on activities in basic astronomy (night sky, stars, galaxies, optics, telescopes, etc.) as well as some more advanced concepts such as lookback time and the expansion of the Universe. Since the inception of our original Astronomy Camp in 2003, our team has grown to include nearly 280 adult leaders, staff, and volunteers from over 79 Councils in 43 states and the District of Columbia so they can, in turn, teach young women essential concepts in astronomy, the night sky environment, applied math, and engineering. Our workshops model what astronomers do by engaging participants in the process of science inquiry, while equipping adults to host astronomy-related programs with

An increasing prevalence since 2010 of Serratia marcescens harbouring the Ambler class A carbapenemase SME prompted us to further characterize these isolates. Isolates harbouring bla(SME) were identified by PCR and sequencing. Phenotypic analysis for carbapenemase activity was carried out by a modified Hodge test and a modified Carba NP test. Antimicrobial susceptibilities were determined by Etest and Vitek 2. Typing was by PFGE of macrorestriction digests. Whole-genome sequencing of three isolates was carried out to characterize the genomic region harbouring the bla(SME)-type genes. All S. marcescens harbouring SME-type enzymes could be detected using a modified Carba NP test. Isolates harbouring bla(SME) were resistant to penicillins and carbapenems, but remained susceptible to third-generation cephalosporins, as well as fluoroquinolones and trimethoprim/sulfamethoxazole. Isolates exhibited diverse genetic backgrounds, though 57% of isolates were found in three clusters. Analysis of whole-genome sequence data from three isolates revealed that the bla(SME) gene occurred in a novel cryptic prophage genomic island, SmarGI1-1. There has been an increasing occurrence of S. marcescens harbouring bla(SME) in Canada since 2010. The bla(SME) gene was found on a genomic island, SmarGI1-1, that can be excised and circularized, which probably contributes to its dissemination amongst S. marcescens. © The Author 2014.

The emergence of antimicrobial resistant bacteria is an important public health and environmental contamination issue. Antimicrobials of β-lactam group accounts for approximately two thirds, by weight, of all antimicrobials administered to humans due to high clinical efficacy and low toxicity. This study explores β-lactam resistance determinant gene (blaTEM) as emerging contaminant in Indo-Gangetic region using qPCR in molecular beacon format. Quantitative Microbial Risk Assessment (QMRA) approach was adopted to predict risk to human health associated with consumption/exposure of surface water, potable water and street foods contaminated with bacteria having blaTEM gene. It was observed that surface water and sediments of the river Ganga and Gomti showed high numbers of blaTEM gene copies and varied significantly (p<0.05) among the sampling locations. The potable water collected from drinking water facility and clinical settings exhibit significant number of blaTEM gene copies (13±0.44-10200±316 gene copies/100mL). It was observed that E.crassipes among aquatic flora encountered in both the rivers had high load of blaTEM gene copies. The information on prevalence of environmental reservoirs of blaTEM gene containing bacteria in Indo-Gangetic region and risk associated will be useful for formulating strategies to protect public from menace of clinical risks linked with antimicrobial resistant bacteria.

The nurse's lived experience of becoming an interprofessional leader.
Stiles, Kim A; Horton-Deutsch, Sara L; Andrews, Catherine A
2014-11-01
In the current complex health care environment, nurses in all practice settings are called on to be leaders in advocating for a healthier future. Health care reform, the rise of the evidence-based practice movement, and the proliferation of new educational options are opening opportunities as never before for nurses to expand their leadership capacity to an interprofessional level. This interpretive phenomenological study conducted with eight nurse participants describes their experience of becoming an interprofessional leader. A team of three nurse researchers interpreted the texts individually and collectively. Interview texts were analyzed hermeneutically to uncover the common shared experience of moving toward common ground with interprofessional leadership as a process, one that not only took time, but also called for self-reflection, deliberate actions, and a new mind-set. This study develops the evidence base for leadership preparation at a time when there is a strong need for interprofessional leaders and educators in health care. Copyright 2014, SLACK Incorporated.

2012-03-01
To examine nurse leaders' change management projects within British Columbia, Canada. British Columbia Nursing Leadership Institute 2007-10 attendees worked on year-long change management initiatives/projects of importance to their respective health-care institutions. Most leaders were in first-line positions with <3 years' experience. Consenting leaders' project reports (N = 133) were content analysed for specific themes: types of projects; scope of projects (e.g. unit or local level, departmental, institutional); influence targets or key stakeholder groups targeted by the projects; leadership successes and challenges. Of study participants, 77% successfully completed their projects. Staff tool and resource development and existing services improvement were major project types. Care delivery teams were the major influence targets. Only 25% of projects were at the unit level. Many projects had broader scopes, such as institutional levels. Participants cited multiple leadership successes, including enhanced leadership styles and organizational skills. First-line nurse leaders were able to successfully manage projects beyond their traditional scope of responsibilities. The majority of projects dealt with staff needs and healthcare restructuring initiatives. Constant change is a global reality. Change management, a universal competency, must be included in leadership development programmes. © 2011 Blackwell Publishing Ltd.

To conceptualize how health care leaders' strategies to increase their influence in their psychosocial work environment are experienced and handled, and may be supported. The complex nature of the psychosocial work environment with increased stress creates significant challenges for leaders in today's health care organizations. Interviews with health care leaders (n = 39) were analysed in accordance with constructivist grounded theory. Compound identities, loyalty commitments and professional interests shape conditions for leaders' influence. Strategies to achieve legitimacy were either to retain clinical skills and a strong occupational identity or to take a full leadership role. Ethical stress was experienced when organizational procedural or consequential legitimacy norms were in conflict with the leaders' own values. Leadership support through socializing processes and strategic support structures may be complementary or counteractive. Support programmes need to have a clear message related to decision-making processes and should facilitate communication between top management, human resource departments and subordinate leaders. Ethical stress from conflicting legitimacy principles may be moderated by clear policies for decision-making processes, strengthened sound networks and improved communication. Supportive programmes should include: (1) sequential and strategic systems for introducing new leaders and mentoring; (2) reflective dialogue and feedback; (3) team development; and (4) decision-making policies and processes.

Changes in commitment to change among leaders in home help services.
Westerberg, Kristina; Tafvelin, Susanne
2015-07-06
The purpose of the this study was to explore the development of commitment to change among leaders in the home help services during organizational change and to study this development in relation to workload and stress. During organizational change initiatives, commitment to change among leaders is important to ensure the implementation of the change. However, little is known of development of commitment of change over time. The study used a qualitative design with semi-structured interviews with ten leaders by the time an organizational change initiative was launched and follow-up one year later. Thematic content analysis was used to analyze the interviews. Commitment to change is not static, but seems to develop over time and during organizational change. At the first interview, leaders had a varied pattern reflecting different dimensions of commitment to change. One year later, the differences between leaders' commitment to change was less obvious. Differences in commitment to change had no apparent relationship with workload or stress. The data were collected from one organization, and the number of participants were small which could affect the results on workload and stress in relation to commitment to change. It is important to support leaders during organizational change initiatives to maintain their commitment. One way to accomplish this is to use management team meetings to monitor how leaders perceive their situation. Qualitative, longitudinal and leader studies on commitment to change are all unusual, and taken together, this study shows new aspects of commitment.

2010-01-01
Would you like to lead a world renowned team that draws out all the talents and expertise of its members and consistently out performs all others in the industry? Ever wonder why so many organizations fail to truly learn from past mistakes only to repeat the same ones at a later date? Are you a program/project manager or team member in a high-risk organization where the decisions made often carry the highest of consequences? Leadership, communication, team building, critical decision-making and continuous team improvement skills and behaviors are mere talking points without the attitudes, commitment and strategies necessary to make them the very fabric of a team. Developing Expert Teams with a Strong Safety Culture, will provide you with proven knowledge and strategies to take your team soaring to heights you may have not thought possible. A myriad of teams have applied these strategies and techniques within their organization team environments: military and commercial aviation, astronaut flight crews, Shuttle flight controllers, members of the Space Shuttle Program Mission Management Team, air traffic controllers, nuclear power control teams, surgical teams, and the fire service report having spectacular success. Many industry leaders are beginning to realize that although the circumstances and environments of these teams may differ greatly to their own, the core elements, governing principles and dynamics involved in managing and building a stellar safety conscious team remain identical.

Being a team leader: newly registered nurses relate their experiences.
Ekström, Louise; Idvall, Ewa
2015-01-01
This paper presents a study that explores how newly qualified registered nurses experience their leadership role in the ward-based nursing care team. A nurse's clinical leadership affects the quality of care provided. Newly qualified nurses experience difficulties during the transition period from student to qualified professional and find it challenging to lead nursing care. Twelve nurses were interviewed and the transcribed texts analysed using qualitative content analysis to assess both manifest and latent content. Five themes were identified: feeling stranded; forming well-functioning teams; learning to lead; having the courage, strength, and desire to lead; and ensuring appropriate care. The findings indicate that many factors limit nurses' leadership but some circumstances are supportive. The leadership prerequisites for newly registered nurses need to improve, emphasizing different ways to create a supportive atmosphere that promotes professional development and job satisfaction. To increase nurse retention and promote quality of care, nurse managers need to clarify expectations and guide and support newly qualified nurses in a planned way. © 2013 John Wiley & Sons Ltd.

Building the occupational health team: keys to successful interdisciplinary collaboration.
Wachs, Joy E
2005-04-01
Teamwork among occupational health and safety professionals, management, and employees is vital to solving today's complex problems cost-effectively. No single discipline can meet all the needs of workers and the workplace. However, teamwork can be time-consuming and difficult if attention is not given to the role of the team leader, the necessary skills of team members, and the importance of a supportive environment. Bringing team members together regularly to foster positive relationships and infuse them with the philosophy of strength in diversity is essential for teams to be sustained and work to be accomplished. By working in tandem, occupational health and safety professionals can become the model team in business and industry delivering on their promise of a safe and healthy workplace for America's work force.

In Enterobacteriaceae, the blaNDM genes have been found in many different genetic contexts, and a wide diversity of plasmid scaffolds bearing those genes has been found. In August 2013, we identified NDM-1-producing Escherichia coli and Enterobacter hormaechei strains from a single rectal swab sample from a patient hospitalized in Rio de Janeiro, Brazil, who had no history of travel abroad. Complete DNA sequencing using the Illumina platform and annotation of the two plasmids harboring the blaNDM-1 gene, one from each strain, showed that they belonged to incompatibility groups IncFIIK and IncX3 and harbored a novel transposon named Tn3000. Similar genetic structures have been identified among other isolates in Brazil but also on plasmids from other continents. Our findings suggest that the blaNDM-1 gene may be transmitted by Tn3000 in different parts of the world. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

β-Lactamase production is one of the most important strategies for Gram-negative bacteria to combat β-lactam antibiotics. Studies of the regulation of β-lactamase expression have largely been focused on the class C β-lactamase AmpC, whose induction by β-lactams requires LysR-type regulator AmpR and permease AmpG-dependent peptidoglycan recycling intermediates. In Shewanella, which is ubiquitous in aquatic environments and is a reservoir for antibiotic resistance, production of the class D β-lactamase BlaA confers bacteria with natural resistance to many β-lactams. Expression of the blaA gene in the genus representative Shewanella oneidensis is distinct from the AmpC paradigm because of the lack of an AmpR homologue and the presence of an additional AmpG-independent regulatory pathway. In this study, using transposon mutagenesis, we identify proteins that are involved in blaA regulation. Inactivation of mrcA and lpoA, which encode penicillin binding protein 1a (PBP1a) and its lipoprotein cofactor, LpoA, respectively, drastically enhances blaA expression in the absence of β-lactams. Although PBP1b and its cognate, LpoB, also exist in S. oneidensis, their roles in blaA induction are dispensable. We further show that the mrcA-mediated blaA expression is independent of AmpG.

This study has been conducted with the aim of ascertaining the relationship between peer leaders in sport teams and the levels of burnout experienced by their team-mates. A total of 219 Spanish athletes involved in football and basketball participated in the study. To measure leadership among peers, we employed the Sports Peer Leadership Scale, which comprises 24 items, grouped into 6 primary factors: empathy, influence on decision making, sports values, social support, training orientation and competition orientation. And to measure burnout, we employed the Athlete Burnout Questionnaire, which comprises 15 items which are indicators of physical and emotional exhaustion, devaluation and reduced sense of accomplishment among athletes. The results led to the conclusion that there is a statistically significant negative relationship between perceived leadership capacity and the levels of burnout experience by a team. The greater the level of leadership capacity perceived, the lower the levels of burnout will be. A multiple regression analysis with total burnout as dependent variable and social and task orientations of the leader as predictors showed standardized regression coefficients of -.241 (p = .010) and -.076 (p = .413), respectively for social and task orientation, being the effect size equal to .089.

Team situational awareness (TSA) is critical for effective teamwork and supports dynamic decision making in unpredictable, time-pressured situations. Simulation provides a platform for developing and assessing TSA, but these efforts are limited by suboptimal measurement approaches. The objective of this study was to develop and evaluate a novel approach to TSA measurement in interprofessional emergency medicine (EM) teams. We performed a multicenter, prospective, simulation-based observational study to evaluate an approach to TSA measurement. Interprofessional emergency medical teams, consisting of EM resident physicians, nurses, and medical students, were recruited from the University of Washington (Seattle, WA) and Wayne State University (Detroit, MI). Each team completed a simulated emergency resuscitation scenario. Immediately following the simulation, team members completed a TSA measure, a team perception of shared understanding measure, and a team leader effectiveness measure. Subject matter expert reviews and pilot testing of the TSA measure provided evidence of content and response process validity. Simulations were recorded and independently coded for team performance using a previously validated measure. The relationships between the TSA measure and other variables (team clinical performance, team perception of shared understanding, team leader effectiveness, and team experience) were explored. The TSA agreement metric was indexed by averaging the pairwise agreement for each dyad on a team and then averaging across dyads to yield agreement at the team level. For the team perception of shared understanding and team leadership effectiveness measures, individual team member scores were aggregated within a team to create a single team score. We computed descriptive statistics for all outcomes. We calculated Pearson's product-moment correlations to determine bivariate correlations between outcome variables with two-tailed significance testing (p < 0.05). A

Emergence of plasmids harbouring bla(NDM-1) is a major public health concern due to their association with multidrug resistance and their potential mobility. PCR was used to detect bla(NDM-1) from clinical isolates of Providencia rettgeri (PR) and Klebsiella pneumoniae (KP). Antimicrobial susceptibilities were determined using Vitek 2. The complete DNA sequence of two bla(NDM-1) plasmids (pPrY2001 and pKp11-42) was obtained using a 454-Genome Sequencer FLX. Contig assembly and gap closures were confirmed by PCR-based sequencing. Comparative analysis was done using BLASTn and BLASTp algorithms. Both clinical isolates were resistant to all β-lactams, carbapenems, aminoglycosides, ciprofloxacin and trimethoprim/sulfamethoxazole, and susceptible to tigecycline. Plasmid pPrY2001 (113 295 bp) was isolated from PR. It did not show significant homology to any known plasmid backbone and contained a truncated repA and novel repB. Two bla(NDM-1)-harbouring plasmids from Acinetobacter lwoffii (JQ001791 and JQ060896) shared 100% similarity to a 15 kb region that contained bla(NDM-1). pPrY2001 also contained a type II toxin/antitoxin system. pKp11-42 (146 695 bp) was isolated from KP. It contained multiple repA genes. The plasmid backbone had the highest homology to the IncFIIk plasmid type (51% coverage, 100% nucleotide identity). The bla(NDM-1) region was unique in that it was flanked upstream by IS3000 and downstream by a novel transposon designated Tn6229. pKp11-42 also contained a number of mutagenesis and plasmid stability proteins. pPrY2001 differed from all known plasmids due to its novel backbone and repB. pKp11-42 was similar to IncFIIk plasmids and contained a number of genes that aid in plasmid persistence.

A Course To Prepare Peer Leaders To Implement a Student-Assisted Learning Method
NASA Astrophysics Data System (ADS)
Tien, Lydia T.; Roth, Vicki; Kampmeier, J. A.
2004-09-01
This article reports our efforts to develop a two-credit course to train undergraduate students to implement a new pedagogical model, Peer-Led Team Learning (PLTL). The leader training course is a collaborative effort of faculty and educational specialists to join pedagogy and chemistry. The syllabus is grounded in the research literature and situated in the context of the specific course in which the peer leaders will work, leading a weekly Workshop. Since the peer leaders take the training course while they are working as leaders, the pedagogical ideas find immediate application. We have taught the course since 1995 to more than 250 undergraduate and graduate students. In practice, our training course is the central mechanism to transform students from Workshop participants to skilled Workshop leaders. In turn, these carefully prepared peer leaders are essential forces for curricular change. In addition to the immediate practical benefits, the training course leads to new working relationships among students, faculty, and educational specialists. As a result, the training course becomes a mechanism to introduce current faculty to a new research literature and to encourage the development of future faculty.

1998-01-01
This study assesses the contributions of the leader power and top management team characteristics to perceived strategic capability. Low age heterogeneity and low tenure heterogeneity were found to have a positive association with perceived adaptability. High diversity in educational specialization was also found to be positively associated with adaptability. Top management perceptions of CEO power were, however, lower among high adaptors. Implications for leadership research, senior management recruitment, and the design of management development for top management teams are discussed.

Pseudomonas aeruginosa is a frequent colonizer of hospitalized patients. They are responsible for serious infections such as meningitis, urological infections, septicemia and pneumonia. Carbapenem resistance of Pseudomonas aeruginosa is currently increasingly reported which is often mediated by production of metallo-β-lactamase (MBL). Multidrug resistant Pseudomonas aeruginosa isolates may involve reduced cell wall permeability, production of chromosomal and plasmid mediated β lactamases, aminoglycosides modifying enzymes and an active multidrug efflux mechanism. This study is aimed to detect the presence and the nature of plasmids among metallo-β-lactamase producing Pseudomonas aeruginosa isolates. Also to detect the presence of bla VIM gene from these isolates. Clinical isolates of Pseudomonas aeruginosa showing the metalo-β-lactamase enzyme (MBL) production were isolated. The MBL production was confirmed by three different methods. From the MBL producing isolates plasmid extraction was done by alkaline lysis method. Plasmid positive isolates were subjected for blaVIM gene detection by PCR method. Two thousand seventy six clinical samples yielded 316 (15.22%) Pseudomonas aeruginosa isolates, out of which 141 (44.62%) were multidrug resistant. Among them 25 (17.73%) were metallo-β-lactamase enzyme producers. Plasmids were extracted from 18 out of 25 isolates tested. Five out of 18 isolates were positive for the blaVIM gene detection by the PCR amplification. The MBL producers were susceptible to polymyxin /colistin with MIC ranging from 0.5 - 2μg/ml. Molecular detection of specific genes bla VIM were positive among the carbapenem resistant isolates.

2017-10-01
The incorporation of team context into research and practice regarding team effectiveness in NGOs projects is a constant challenge. The research seeks to address the gap and identify the critical determinants of team effectiveness in projects undertaken by non-governmental organizations. Using a systematic process, the study involved both literature and focus group discussions to generate the required items. A total of 157 respondents (Team Members and Team Leaders) were part of the study that filled the questionnaires. Using exploratory factor analysis followed by confirmatory factor analysis, both convergent and discriminant validity was established. The present study found that team effectiveness in NGO social projects has a total of seven dimensions namely: Inter team coordination, community social linkage, team performance, knowledge, skills, and attitudes, leadership communication and engagement, decision making and information sharing, and team formation. There is a significant lack of research on team effectiveness in NGO projects. Where considerably large proportion of research on team effectiveness has focused on the corporate sector, the non-governmental teams have been neglected. This study clearly highlights the determinants that make up team effectiveness in NGOs. The determinants identified will help to specifically look at the effectiveness of teams in NGO projects. The study would help NGOs identify the dimensions in which they may be performing in a weaker manner and direct their energies in improving the factors. Copyright © 2017 Elsevier Ltd.

Horizontal gene transfer may occur between distantly related bacteria, thus leading to genetic plasticity and in some cases to acquisition of novel resistance traits. Proteus mirabilis is an enterobacterial species responsible for human infections that may express various acquired β-lactam resistance genes, including different classes of carbapenemase genes. Here we report a Proteus mirabilis clinical isolate (strain 1091) displaying resistance to penicillin, including temocillin, together with reduced susceptibility to carbapenems and susceptibility to expanded-spectrum cephalosporins. Using biochemical tests, significant carbapenem hydrolysis was detected in P. mirabilis 1091. Since PCR failed to detect acquired carbapenemase genes commonly found in Enterobacteriaceae, we used a whole-genome sequencing approach that revealed the presence of bla OXA-58 class D carbapenemase gene, so far identified only in Acinetobacter species. This gene was located on a 3.1-kb element coharboring a bla AmpC -like gene. Remarkably, these two genes were bracketed by putative XerC-XerD binding sites and inserted at a XerC-XerD site located between the terminase-like small- and large-subunit genes of a bacteriophage. Increased expression of the two bla genes resulted from a 6-time tandem amplification of the element as revealed by Southern blotting. This is the first isolation of a clinical P. mirabilis strain producing OXA-58, a class D carbapenemase, and the first description of a XerC-XerD-dependent insertion of antibiotic resistance genes within a bacteriophage. This study revealed a new role for the XerC-XerD recombinase in bacteriophage biology. Copyright © 2017 American Society for Microbiology.

In 2009, Griffith University School of Dentistry and Oral Health, in Queensland, Australia, introduced into its various curricula the concept of team-based treatment planning (TBTP), aiming to facilitate intraprofessional, interdisciplinary training and peer learning among its students. Fifty student teams were organized, each of which included students from three programs (Dental Science, Oral Health Therapy, and Dental Technology) and three years of study (third-, fourth-, and fifth-year students). This study prospectively evaluated the impact of TBTP on students' perceptions and attitudes towards teamwork and their role in a team of peers. A total of 202 students who participated in fifty TBTP teams were prospectively surveyed at baseline and at six and twelve months after introduction of TBTP. "Reliable" and "responsible" were reported to be the most important qualities of both an effective team leader and member. Fifth-year students identified "hard-working" as an important quality of the ideal leader as opposed to the fourth-year students who ranked "supportive" higher. Attitudes of the fifth-year students towards TBTP appeared to have declined significantly from the previous years, while fourth-year students remained consistently more positive. In addition, fourth-year students appeared more likely to enjoy working in a team and considered themselves more effective in a team. No gender differences were observed, other than female students' appearing less confident to lead a team. It was concluded that the function of student-directed interdisciplinary, intraprofessional treatment planning teams might pose disproportionate strain on fifth-year students, impacting their attitudes to such modes of work.

ICU shows increasing incidence of infection associated with the use of invasive procedures for the diagnostic purpose as well as the indiscriminate use of antibiotics. Pseudomonas aeruginosa and Acinetobacter species are "very successful" pathogen and the emergence of the Metallo-β-Lactamases (MBL) is becoming a therapeutic challenge. To isolate the Nonfermenting Gram negative bacilli from the ICU samples. To identify the metallo betalactamase producers and to detect the bla gene presence among the Pseudomonas aeruginosa and Acinetobacter baumannii . The Nonfermenting Gram negative bacilli isolates from the ICU samples were taken over for 5 years (2009-2014) in a tertiary care hospital. The isolates of Pseudomonas species and Acinetobacter species were confirmed by API analyser and processed according to standard procedures. Detection of the MBL producers were done by E strip method and subjected for bla gene detection by PCR method. In our study a total of 195 isolates of NFGNB were obtained from various ICU. Of these MBL producers, 26 % were Pseudomonas aeruginosa and 25 % were Acinetobacter baumannii . The subtypes of bla VIM MBL producing P.aeruginosa were 26%. The predominant gene coding for MBL activity in A.baumannii were found to be bla OXA gene 11.9%. The gene accession numbers were KF975367, KF975372. We have to control the development and dissemination of these superbugs among the ICU's.

To succeed as a biomedical researcher, the ability to flourish in interdisciplinary teams of scientists is becoming ever more important. Institutions supported by the Clinical and Translational Science Awards (CTSAs) from the National Institutes of Health have a specific mandate to educate the next generation of clinical and translational researchers. While they strive to advance integrated and interdisciplinary approaches to education and career development in clinical and translational science, general approaches and evaluation strategies may differ, as there is no single, universally accepted or standardized approach. It is important, therefore, to learn about the different approaches used to determine what is effective. We implemented a Web-based survey distributed to education leaders at the 60 funded CTSA institutions; 95% responded to the survey, which included questions on the importance of preparation for interdisciplinary team science careers, methods used to provide such training, and perceived effectiveness of these training programs. The vast majority (86%) of education leaders reported that such training is important, and about half (52%) of the institutions offer such training. Methods of training most often take the form of courses and seminars, both credit bearing and noncredit. These efforts are, by and large, perceived as effective by the training program leaders, although long-term follow-up of trainees would be required to fully evaluate ultimate effectiveness. Results from the survey suggest that CTSA education directors believe that specific training in interdisciplinary team science for young investigators is very important, but few methodologies are universally practiced in CTSA institutions to provide training or to assess performance. Four specific recommendations are suggested to provide measurable strategic goals for education in team science in the context of clinical and translational research.

Stressful events can directly produce significant alterations in subsequent sleep, in particular rapid eye movement sleep (REM); however, the neural mechanisms underlying the process are not fully known. Here, we investigated the role of the basolateral nuclei of the amygdala (BLA) in regulating the effects of stressful experience on sleep. We used optogenetics to briefly inhibit glutamatergic cells in BLA during the presentation of inescapable footshock (IS) and assessed effects on sleep, the acute stress response, and fear memory. c-Fos expression was also assessed in the amygdala and the medial prefrontal cortex (mPFC), both regions involved in coping with stress, and in brain stem regions implicated in the regulation of REM. Compared to control mice, peri-shock inhibition of BLA attenuated an immediate reduction in REM after IS and produced a significant overall increase in REM. Moreover, upon exposure to the shock context alone, mice receiving peri-shock inhibition of BLA during training showed increased REM without altered freezing (an index of fear memory) or stress-induced hyperthermia (an index of acute stress response). Inhibition of BLA during REM under freely sleeping conditions enhanced REM only when body temperature was high, suggesting the effect was influenced by stress. Peri-shock inhibition of BLA also led to elevated c-Fos expression in the central nucleus of the amygdala and mPFC and differentially altered c-Fos activity in the selected brain stem regions. Glutamatergic cells in BLA can modulate the effects of stress on REM and can mediate effects of fear memory on sleep that can be independent of behavioral fear. © Sleep Research Society 2017.

Team working is an integral aspect of primary care, but barriers to effective team working can limit the effectiveness of a primary care team (PCT). The establishment of new PCTs in Ireland provides an excellent opportunity to explore team working in action. The aim of this qualitative study was to explore the experiences of team members working in a PCT. Team members (n = 19) from two PCTs were interviewed from May to June 2010 using a semi-structured interview guide. All interviews were audio-recorded and transcribed. Data were analysed using NVivo (version 8). Thematic analysis was used to explore the data. We identified five main themes that described the experiences of the team members. The themes were support for primary care, managing change, communication, evolution of roles and benefits of team working. Team members were generally supportive of primary care and had experienced benefits to their practice and to the care of their patients from participation in the team. Regular team meetings enabled communication and discussion of complex cases. Despite the significant scope for role conflict due to the varied employment arrangements of the team members, neither role nor interpersonal conflict was evident in the teams studied. In addition, despite the unusual team structure in Irish PCTs - where there is no formally appointed team leader or manager - general issues around team working and its benefits and challenges were very similar to those found in other international studies. This suggests, in contrast to some studies, that some aspects of the leadership role may not be as important in successful PCT functioning as previously thought. Nonetheless, team leadership was identified as an important issue in the further development of the teams. © 2014 John Wiley & Sons Ltd.

Organizational socialization in team sport environments.
Benson, A J; Evans, M B; Eys, M A
2016-04-01
Socialization tactics are often used to manage initial group member interactions in a way that facilitates transition experiences. Although this process is heavily researched in organizational contexts, we sought to extend this line of inquiry to sport by examining the nature of socialization tactics used to integrate new members into existing teams. Interviews were conducted with 12 coaches and 12 athletes from several Canadian Interuniversity Sport teams to explore the nature of socialization and the circumstances underscoring why certain approaches are taken over others. A key process involved establishing congruency of role expectations between incoming athletes and group leaders, and socialization processes balanced expectations of conformity with encouragement of individual personalities within the group. A conceptual basis to examine socialization into team sport environments is discussed in relation to the extant organizational theories, and the practical implications of delineating sport socialization tactics are forwarded. © 2015 John Wiley & Sons A/S.

To explore how team processes support nursing teams in hospital units during every day work. Due to their close proximity to patients, nurses are central to the process of maintaining patient safety. Globally, changes in models of care delivery by nurses, inclusive of team nursing are being considered. This qualitative study used purposive sampling in a single hospital and participants were nurses employed to work on a paediatric unit. Data was collected using non-participant observation. Thematic analysis was used to analyse and code data to create themes. Three clear themes emerged. Theme 1:"We are a close knit team"; Behaviours building a successful team"- outlines expectations regarding how members are to behave when establishing, nurturing and managing a team. Theme 2: "Onto it"; Ways of interacting with each other" - Identifies the expected pattern of relating within the team which contribute to shared understanding and actions. Theme 3: "No point in second guessing"; Maintaining a global view of the unit" - focuses on the processes for monitoring and reporting signals that team performance is on course or breaking down and includes accepting responsibility to lead the team and team members having a widespread sensitivity to what needs to happen. Essential to successful teamwork is the interplay and mutuality of team members and team leaders. Leadership behaviours exhibited in this study provide useful insights to how informal and shared or distributed leadership of teams may be achieved. Without buy-in from team members, teams may not achieve successful desired outcomes. It is not sufficient for teams to rely on current successful outcomes, as they need to be on the look-out for new ways to ensure that they can anticipate possible risks or threats to the team before harm is done.

Introduction:Pseudomonas aeruginosa is a frequent colonizer of hospitalized patients. They are responsible for serious infections such as meningitis, urological infections, septicemia and pneumonia. Carbapenem resistance of Pseudomonas aeruginosa is currently increasingly reported which is often mediated by production of metallo-β-lactamase (MBL). Multidrug resistant Pseudomonas aeruginosa isolates may involve reduced cell wall permeability, production of chromosomal and plasmid mediated β lactamases, aminoglycosides modifying enzymes and an active multidrug efflux mechanism. Objective: This study is aimed to detect the presence and the nature of plasmids among metallo-β-lactamase producing Pseudomonas aeruginosa isolates. Also to detect the presence of bla VIM gene from these isolates. Materials and Methods: Clinical isolates of Pseudomonas aeruginosa showing the metalo-β-lactamase enzyme (MBL) production were isolated. The MBL production was confirmed by three different methods. From the MBL producing isolates plasmid extraction was done by alkaline lysis method. Plasmid positive isolates were subjected for blaVIM gene detection by PCR method. Results: Two thousand seventy six clinical samples yielded 316 (15.22%) Pseudomonas aeruginosa isolates, out of which 141 (44.62%) were multidrug resistant. Among them 25 (17.73%) were metallo-β-lactamase enzyme producers. Plasmids were extracted from 18 out of 25 isolates tested. Five out of 18 isolates were positive for the blaVIM gene detection by the PCR amplification. Conclusion: The MBL producers were susceptible to polymyxin /colistin with MIC ranging from 0.5 – 2μg/ml. Molecular detection of specific genes bla VIM were positive among the carbapenem resistant isolates. PMID:25120980

To characterize a pan-drug-resistant Serratia marcescens clinical isolate carrying the New Delhi metallo-β-lactamase (NDM)-1. The presence of β-lactamase genes was examined by PCR and sequencing. Antibiotic susceptibility was determined by antibiotic gradient test. Transformation assays, transconjugation assays, PFGE and PCR-based replicon typing were used for plasmid analysis. Horizontal gene transfer was evaluated by liquid mating using Escherichia coli J53 as a recipient. Pathogenicity of NDM-1 expressing S. marcescens was analysed using the Galleria mellonella infection model. S. marcescens isolate SM1890 was non-susceptible to all tested antibiotics, with minocycline retaining intermediate activity. blaNDM-1 was located on a 140 kb IncA/C-type plasmid which was transferable to E. coli and Klebsiella pneumoniae by conjugation. The LD50 of the NDM-positive, SM1890 isolate was higher than that of other, NDM-1 negative, S. marcescens strains. The presence of a blaNDM-1-harbouring IncA/C plasmid resulted in marked resistance to β-lactam antibiotics, but had no significant effect on virulence of isogenic strains. Because of the intrinsic resistance of S. marcescens to colistin and reduced susceptibility to tigecycline, treatment options for infections by NDM-1-positive isolates are extremely limited in this species. © The Author 2014.

Leading teams during simulated pediatric emergencies: a pilot study
Coolen, Ester H; Draaisma, Jos M; den Hamer, Sabien; Loeffen, Jan L
2015-01-01
Purpose Leadership has been identified as a key variable for the functioning of teams and as one of the main reasons for success or failure of team-based work systems. Pediatricians often function as team leaders in the resuscitation of a critically ill child. However, pediatric residents often report having little opportunity to perform in the role of team leader during residency. In order to gain more insight into leadership skills and behaviors, we classified leadership styles of pediatric residents during simulated emergencies. Methods We conducted a prospective quantitative study to investigate leadership styles used by pediatric residents during simulated emergencies with clinical deterioration of a child at a pediatric ward. Using videotaped scenarios of 48 simulated critical events among 12 residents, we were able to classify verbal and nonverbal communication into different leadership styles according to the situational leadership theory. Results The coaching style (mean 54.5%, SD 7.8) is the most frequently applied by residents, followed by the directing style (mean 35.6%, SD 4.1). This pattern conforms to the task- and role-related requirements in our scenarios and it also conforms to the concept of situational leadership. We did not find any significant differences in leadership style according to the postgraduate year or scenario content. Conclusion The model used in this pilot study helps us to gain a better understanding of the development of effective leadership behavior and supports the applicability of situational leadership theory in training leadership skills during residency.

CONTEXT: ICU shows increasing incidence of infection associated with the use of invasive procedures for the diagnostic purpose as well as the indiscriminate use of antibiotics. Pseudomonas aeruginosa and Acinetobacter species are “very successful” pathogen and the emergence of the Metallo-β-Lactamases (MBL) is becoming a therapeutic challenge. AIMS: To isolate the Nonfermenting Gram negative bacilli from the ICU samples. To identify the metallo betalactamase producers and to detect the bla gene presence among the Pseudomonas aeruginosa and Acinetobacter baumannii. SETTINGS AND DESIGN: The Nonfermenting Gram negative bacilli isolates from the ICU samples were taken over for 5 years (2009-2014) in a tertiary care hospital. METHODS AND MATERIALS: The isolates of Pseudomonas species and Acinetobacter species were confirmed by API analyser and processed according to standard procedures. Detection of the MBL producers were done by E strip method and subjected for bla gene detection by PCR method. RESULTS: In our study a total of 195 isolates of NFGNB were obtained from various ICU. Of these MBL producers, 26 % were Pseudomonas aeruginosa and 25 % were Acinetobacter baumannii. The subtypes of blaVIM MBL producing P.aeruginosa were 26%. The predominant gene coding for MBL activity in A.baumannii were found to be blaOXA gene 11.9%. The gene accession numbers were KF975367, KF975372. CONCLUSIONS: We have to control the development and dissemination of these superbugs among the ICU's. PMID:29692589

Metallo-β-lactamase (MBL)-producing Pseudomonas aeruginosa is a significant pathogen in burn patients. The aim of this study was to determine the prevalence of carbapenem-resistant P. aeruginosa isolates, including those resistant to imipenemase (IMP), in a burn unit in Isfahan, Iran. One hundred and fifty P. aeruginosa isolates from burn patients were tested for antibiotic susceptibility by the disc diffusion method in accordance with CLSI guidelines. Production of MBL was identified with the EDTA disk method. DNA was purified from the MBL-positive isolates, and detection of the bla IMP gene was performed with PCR. Fifty-seven out of 150 (38%) isolates were multi-drug resistant (MDR), and 93 (62%) were extensively-drug resistant (XDR). Among all isolates, the resistance rate to ciprofloxacin, tobramycin, imipenem, meropenem, amikacin, ceftazidime, and cefepime was higher than 90%, while the resistance rates to piperacillin/tazobactam and aztreonam were 70.7% and 86%, respectively. Colistin and polymyxin B remained the most effective studied antibiotics. All of the imipenem-resistant P. aeruginosa isolates were MBL-positive, and 107 out of 144 (74.3%) of the MBL isolates were positive for the bla IMP gene. The results of this study show that the rate of P. aeruginosa -caused burn wound infections was very high, and many of the isolates were resistant to three or more classes of antimicrobials. Such extensive resistance to antimicrobial classes is important because few treatment options remain for patients with burn wound infections. bla IMP -producing P. aeruginosa isolates are a rising threat in burn-care units, and should be controlled by conducting infection-control assessments.

PURPOSE: The purpose of this study was to investigate the relations between leaders' communication styles and charismatic leadership, human-oriented leadership (leader's consideration), task-oriented leadership (leader's initiating structure), and leadership outcomes. METHODOLOGY: A survey was conducted among 279 employees of a governmental organization. The following six main communication styles were operationalized: verbal aggressiveness, expressiveness, preciseness, assuredness, supportiveness, and argumentativeness. Regression analyses were employed to test three main hypotheses. FINDINGS: In line with expectations, the study showed that charismatic and human-oriented leadership are mainly communicative, while task-oriented leadership is significantly less communicative. The communication styles were strongly and differentially related to knowledge sharing behaviors, perceived leader performance, satisfaction with the leader, and subordinate's team commitment. Multiple regression analyses showed that the leadership styles mediated the relations between the communication styles and leadership outcomes. However, leader's preciseness explained variance in perceived leader performance and satisfaction with the leader above and beyond the leadership style variables. IMPLICATIONS: This study offers potentially invaluable input for leadership training programs by showing the importance of leader's supportiveness, assuredness, and preciseness when communicating with subordinates. ORIGINALITY/VALUE: Although one of the core elements of leadership is interpersonal communication, this study is one of the first to use a comprehensive communication styles instrument in the study of leadership.

Objective There is growing emphasis on health care organizations to ensure that lay people are meaningfully engaged as partners on research teams. Our aim was to explore the perspectives of patients, family members and informal caregivers who have been involved on health care research teams in Canada and elicit their recommendations for meaningful engagement. Methods We conducted a qualitative study guided by thematic analysis of transcripts of focus groups and interviews of 19 experienced patient research partners in Canada. Results We identified four main themes: research environment, expectations, support and value, which highlight participants' combined perspectives on important factors to ensure their engagement in research is meaningful. Conclusions Our findings add to the evolving evidence base on the perspectives of lay people involved in health care research and their recommendations for research leaders on meaningful engagement. Our study suggests that research leaders should provide a welcoming research environment, outline appropriate expectations for patient research partners on research teams, support patient research partners' engagement in projects and recognize the value patient research partners bring to health research.

Team working in intensive care: current evidence and future endeavors.
Richardson, Joanne; West, Michael A; Cuthbertson, Brian H
2010-12-01
It has recently been argued that the future of intensive care medicine will rely on high quality management and teamwork. Therefore, this review takes an organizational psychology perspective to examine the most recent research on the relationship between teamwork, care processes, and patient outcomes in intensive care. Interdisciplinary communication within a team is crucial for the development of negotiated shared treatment goals and short-team patient outcomes. Interventions for maximizing team communication have received substantial interest in recent literature. Intensive care coordination is not a linear process, and intensive care teams often fail to discuss how to implement goals, trigger and align activities, or reflect on their performance. Despite a move toward interdisciplinary team working, clinical decision-making is still problematic and continues to be perceived as a top-down and authoritative process. The topic of team leadership in intensive care is underexplored and requires further research. Based on findings from the most recent research evidence in medicine and management, four principles are identified for improving the effectiveness of team working in intensive care: engender professional efficacy, create stable teams and leaders, develop trust and participative safety, and enable frequent team reflexivity.

INTRODUCTION: This study was conducted to assess the prevalence of metallo-beta-lactamases (MBLs) in general and blaNDM-1 in particular. It also aimed at evaluating clinical characteristics and outcome in patients infected with MBLs. MATERIALS AND METHODS: A total of 116 carbapenem-resistant Gram-negative bacilli (CRGNB) were evaluated in the study. These CRGNB were tested for MBL production both phenotypically for MBLs and genotypically for blaNDM-1 gene by polymerase chain reaction (PCR). Representative stains of NDM-1 isolates were further sequenced by Triyat Scientific Co., (Nagpur, India). RESULTS: Among 116 CRGNB Citrobacter species 28 (24.13%) was the most common pathogen. Phenotypically, MHT, imipenem-EDTA (IPM-EDTA) double-disk synergy test and IPM-EDTA combined disk synergy test (CDST) detected MBL production in 105 (90.51%), 96 (81.03%), and 87 (75%) CRGNB, respectively. However, blaNDM-1 genes were detected in 66 (56.89%) isolates. The prevalence of blaNDM-1 gene was highest among Escherichia coli 26 (100%). Considering PCR as gold standard, it was observed that IMP-EDTA CDST was most specific (78.38%) while MHT was most sensitive (97.47%). Results of blaNDM-1 gene by PCR were further confirmed by sequencing (Triyat genomics, Nagpur). All the 11 representative strains were confirmed to be an NDM-1 gene. The presence of MBLs in our group of patients (non-Intensive Care Unit patients) is a cause for concern. However, on tracing their outcome, it was interesting to note that while the duration of stay lengthened in a large number of patients 112 (96.5%), mortality was relatively low 5 (4.31%). CONCLUSION: The results of this study provide insight into the prevalence of MBLs, including blaNDM-1, in a tertiary care hospital. Antibiotic stewardship implemented in all seriousness may to a great extent stave off the impending pan-drug resistance. The surprising outcome of our patients suggests either that the bacteria trade off virulence for drug resistance or

Team sponsors in community-based health leadership programs.
Patterson, Tracy Enright; Dinkin, Donna R; Champion, Heather
2017-05-02
Purpose The purpose of this article is to share the lessons learned about the role of team sponsors in action-learning teams as part of community-based health leadership development programs. Design/methodology/approach This case study uses program survey results from fellow participants, action learning coaches and team sponsors to understand the value of sponsors to the teams, the roles they most often filled and the challenges they faced as team sponsors. Findings The extent to which the sponsors were perceived as having contributed to the work of the action learning teams varied greatly from team to team. Most sponsors agreed that they were well informed about their role. The roles sponsors most frequently played were to provide the teams with input and support, serve as a liaison to the community and serve as a sounding board, motivator and cheerleader. The most common challenges or barriers team sponsors faced in this role were keeping engaged in the process, adjusting to the role and feeling disconnected from the program. Practical implications This work provides insights for program developers and community foundations who are interested in building the capacity for health leadership by linking community sponsors with emerging leaders engaged in an action learning experience. Originality/value This work begins to fill a gap in the literature. The role of team sponsors has been studied for single organization work teams but there is a void of understanding about the role of sponsors with multi-organizational teams working to improve health while also learning about leadership.

Communication between members of the cardiac arrest team--a postal survey.
Pittman, J; Turner, B; Gabbott, D A
2001-05-01
Effective communication enhances team building and is perceived to improve the quality of team performance. A recent publication from the Resuscitation Council (UK) has highlighted this fact and recommended that cardiac arrest team members make contact daily. We wished to identify how often members of this team communicate prior to a cardiopulmonary arrest. A questionnaire on cardiac arrest team composition, leadership, communication and debriefing was distributed nationally to Resuscitation Training Officers (RTOs) and their responses analysed. One hundred and thirty (55%) RTOs replied. Physicians and anaesthetists were the most prominent members of the team. The Medical Senior House Officer is usually nominated as the team leader. Eighty-seven centres (67%) have no communication between team members prior to attending a cardiopulmonary arrest. In 33%, communication occurs but is either informal or fortuitous. The RTOs felt that communication is important to enhance team dynamics and optimise task allocation. Only 7% achieve a formal debrief following a cardiac arrest. Communication between members of the cardiac arrest team before and after a cardiac arrest is poor. Training and development of these skills may improve performance and should be prioritised. Team leadership does not necessarily reflect experience or training.

The purpose of this study was to examine the main and interaction effects of perceived organisational support, span of control and leadership rank on novice nurse leaders' organisational commitment. As nurse leaders' organisational commitment is eroded at times of healthcare restructuring, it is important to study factors associated with organisational commitment. Cross-sectional data from 69 novice nurse leaders, collected via mailed surveys at two time points, were analysed using hierarchical regression. The findings supported our hypotheses about the positive effect of perceived organisational support, the positive effect of leadership rank and the negative effect of span of control on novice nurse leaders' organisational commitment. In addition, perceived organisational support was shown to moderate the negative effect of span of control on novice nurse leaders' organisational commitment at time 2. Organisational strategies aimed at supporting nurse leaders, and attention to span of control, are required to enhance the organisational commitment of novice nurse leaders. Nurse leaders with a wide span of control, in particular those with little leadership experience, need to adopt leadership strategies that maximise their effectiveness, such as organising smaller work groups or teams within their wide span of control. © 2013 John Wiley & Sons Ltd.

8 ways to build collaborative teams.
Gratton, Lynda; Erickson, Tamara J
2007-11-01
Executing complex initiatives like acquisitions or an IT overhaul requires a breadth of knowledge that can be provided only by teams that are large, diverse, virtual, and composed of highly educated specialists. The irony is, those same characteristics have an alarming tendency to decrease collaboration on a team. What's a company to do? Gratton, a London Business School professor, and Erickson, president of the Concours Institute, studied 55 large teams and identified those with strong collaboration despite their complexity. Examining the team dynamics and environment at firms ranging from Royal Bank of Scotland to Nokia to Marriott, the authors isolated eight success factors: (1) "Signature" relationship practices that build bonds among the staff, in memorable ways that are particularly suited to a company's business. (2) Role models of collaboration among executives, which help cooperation trickle down to the staff. (3) The establishment of a "gift culture," in which managers support employees by mentoring them daily, instead of a transactional "tit-for-tat culture", (4) Training in relationship skills, such as communication and conflict resolution. (5) A sense of community, which corporate HR can foster by sponsoring group activities. (6) Ambidextrous leadership, or leaders who are both task-oriented and relationship-oriented. (7) Good use of heritage relationships, by populating teams with members who know and trust one another. (8) Role clarity and task ambiguity, achieved by defining individual roles sharply but giving teams latitude on approach. As teams have grown from a standard of 20 members to comprise 100 or more, team practices that once worked well no longer apply. The new complexity of teams requires companies to increase their capacity for collaboration, by making long-term investments that build relationships and trust, and smart near-term decisions about how teams are formed and run.

Social isolation during the vulnerable period of adolescence contributes to the occurrence of psychiatric disorders and profoundly affects brain development and adult behavior. Although the impact of social isolation during adolescence on anxiety behaviors has been well studied, much less is known about the onset and underlying mechanisms of these behaviors. We observed that following 2 weeks, but not 1 week, of social isolation, adolescent mice exhibited anxiety behaviors. Strikingly, the mGluR5 protein levels in the amygdala increased concomitantly with anxiety behaviors, and both intraperitoneal administration and intra-basolateral amygdala (BLA) infusion of MPEP, a metabotropic glutamate receptor 5 antagonist, normalized anxiety behaviors. Furthermore, electrophysiological studies showed that 2 weeks of social isolation during adolescence facilitated pyramidal neuronal excitability in the BLA, which could be normalized by MPEP. Together, these results reveal a critical period in adolescence during which social isolation can induce anxiety behaviors and facilitate BLA pyramidal neuronal excitability, both of which are mediated by mGluR5, thus providing mechanistic insights into the onset of anxiety behaviors after social isolation during adolescence.

The crystal structure of Bla g 2 was solved in order to investigate the structural basis for the allergenic properties of this unusual protein. This is the first structure of an aspartic protease in which conserved glycine residues, in two canonical DTG triads, are substituted by different amino acid residues. Another unprecedented feature revealed by the structure is the single phenylalanine residue insertion on the tip of the flap, with the side-chain occupying the S1 binding pocket. This and other important amino acid substitutions in the active site region of Bla g 2 modify the interactions in the vicinity ofmore » the catalytic aspartate residues, increasing the distance between them to {approx}4 {angstrom} and establishing unique direct contacts between the flap and the catalytic residues. We attribute the absence of substantial catalytic activity in Bla g 2 to these unusual features of the active site. Five disulfide bridges and a Zn-binding site confer stability to the protein, which may contribute to sensitization at lower levels of exposure than other allergens.« less

Coltice, Nicolas; Bocher, Marie
2016-04-01
The project AUGURY was selected in 2014 for a ERC consolidator grant. Like many of these projects, a new team is built almost from scratch, focused on a common scientific goal. In this project, the team was mostly feminine, being 5 women and 1 man. In a masculine world like geosciences, this situation revealed stereotypical reactions and behaviors. Especially when the only man is the leader of the project, shortcuts are easily made. We had to develop strategies to work against inappropriate situations, and we started to use the AUGURY project as a platform to promote equal opportunity in our department, and beyond. The two of us will present (1) how the team was put together for the project and show how the geodynamics community is more and more feminine, (2) how the team responded to the scientific challenges as a group of persons working together, and (3) how the team faced the challenges of its environment regarding equal opportunity.

The Mental Health Team: Evaluation From a Professional Viewpoint. A Qualitative Study.
Pileño, María Elena; Morillo, Javier; Morillo, Andrea; Losa-Iglesias, Marta
2018-04-01
Health care institutions include workers who must operate in accordance with the requirements of the position, even though there are psychosocial influences that can affect the stability of the worker. To analyze the organizational culture of the team of professionals who work in the mental health network. A qualitative methodology was used to assess a sample of 55 mental health professionals who have been practicing for at least 5years. "Team" was the overall topic. The subtopics within "Team" were: getting along in the unit, getting along with the patient, personal resources for dealing with patients, adaptive resources of team members and, resources that the team uses in their group activities. It was observed that the team does not work with a common objective and needs an accepted leader to manage the group. The definition and acceptance of roles can result in conflict. By increasing the skill level of each worker, the multidisciplinary team would be more collaborative. Copyright © 2017 Elsevier Inc. All rights reserved.

Carbapenem-resistance among enterobacteriaceae has become a global health concern. The objective of this study was to understand NDM producing enterobacteriaceae and their genetic basis of resistance, spreading in neonatal intensive care unit. Carbapenem resistant NDM producing enterobacteriaceae isolates were recovered from rectal swab and blood sample of infants admitted in NICU. These were determined by using Carba-NP test. All isolates were identified using BD PhoenixTM−100 and MICs were determined by broth microdilution method. The blaNDM and associated resistant markers were checked by PCR followed by sequencing. Moreover, ERIC-PCR and genetic environment of blaNDM gene were also performed for the analysis of clonal relationship and genetic surrounding of the strains. We characterized 44 isolates with blaNDM variants in Escherichia coli (45.5%), Klebsiella pneumoniae (40.9%), Citrobacter freundii (4.5%), Citrobacter braakii (2.3%), Klebsiella oxytoca (2.3%), Enterobacter cloacae (2.3%), Enterobacter aerogenes (2.2%) from NICU, showing resistance against all antibiotics except colistin and polymixin B. ISAba125 and bleomycin gene were found surrounding all blaNDM variants, besides class I integron on plasmid. (ERIC)-PCR data revealed non-clonal relatedness among most of the isolates. The transfer of resistant markers was confirmed by conjugation experiment. The PCR-based replicon typing was carried out using DNA of transconjugants. These isolates carried NDM-1 (20.45%), NDM-4 (36.36%), NDM-5 (38.64%), NDM-7 (4.55%), along with OXA, CMY, and SHV variants on conjugative plasmid of IncFIA, IncFIC, IncF, IncK, IncFIB, IncB/O, IncHI1, IncP, IncY, IncFIIA, IncI1, and IncN types. An increased number of carbapenem-resistant NDM producing enterobacteriaceae isolates recovered from NICU which is alarming signal for health workers and policy makers. Hence, it is utmost important to think about infection control measures. PMID:29563908

Can the language used and the patterns of communication differentiate a multidisciplinary team from an interprofessional team? This research question arose from an unexpected outcome of a study that investigated clinical reasoning of health professional team members in the elder care wards of two different hospitals. The issue at stake was the apparent disparity in the way in which the two teams communicated. To further explore this, the original transcribed interview data was analysed from a symbolic interactionist perspective in order that the language and communication patterns between the two teams could be identified and compared. Differences appeared to parallel the distinctions between multidisciplinary and interprofessional teams as reported in the literature. Our observations were that an interprofessional team was characterized by its use of inclusive language, continual sharing of information between team members and a collaborative working approach. In the multidisciplinary team, the members worked in parallel, drawing information from one another but did not have a common understanding of issues that could influence intervention. The implications of these communication differences for team members, team leaders and future research are then discussed.

Trust in direct leaders and top leaders: A trickle-up model.
Fulmer, C Ashley; Ostroff, Cheri
2017-04-01
Low levels of employee trust in top leaders pose challenges to organizations with respect to retention, performance, and profits. This research examines how trust in top leaders can be fostered through the relationships individuals have with their direct leaders. We propose a trickle-up model whereby trust in direct leaders exerts an upward influence on trust in top leaders. Drawing on the group value model, we predict that direct leaders' procedural justice serves as the key mechanism in facilitating the trickle-up process. Further, this process should be particularly strong for employees high on vertical collectivism, and the trickled-up trust in top leaders should exert a stronger impact on employees' overall performance in the organization than trust in direct leaders. Multiphase and multisource data from 336 individuals support these hypotheses. The findings advance our understanding of trust and leadership by highlighting that trust in leaders at different levels does not form independently and that trust in leaders trickles up across hierarchical levels.

Sport and exercise participation exert a positive effect on numerous aspects of individuals' health. Although sport and exercise leaders have generally been observed to play a key role in shaping group members' behavior, our understanding of their impact on group members' attendance in sport and exercise sessions is limited. To address this, and building on promising findings in other domains, we examined the associations between perceptions of sport and exercise leaders' engagement in social identity leadership, group identification, and attendance. A sample of 583 participants from sports teams (n = 307) and exercise groups (n = 276) completed questionnaires measuring identity leadership, group identification, and attendance. Analyses demonstrated that perceptions of leader engagement in social identity leadership were positively associated with members' group identification, and that this in turn was positively associated with their attendance in either a sports group or an exercise group. Moreover, there was a significant indirect effect for perceptions of leader engagement in identity leadership on group members' attendance through their greater identification with these groups. Findings highlight the importance of considering the impact sport and exercise leaders have on group members' attendance and suggest that leaders who represent, advance, create, and embed a shared sense of identity (ie, a shared sense of "us") among attendees can promote participation in sport and exercise. © 2018 The Authors.

Members' sensemaking in a multi-professional team.
Rovio-Johansson, Airi; Liff, Roy
2012-01-01
The aim of this study is to investigate sensemaking as interaction among team members in a multi-professional team setting in a new public management context at a Swedish Child and Youth Psychiatric Unit. A discursive pragmatic approach grounded in ethonomethodology is taken in the analysis of a treatment conference (TC). In order to interpret and understand the multi-voiced complexity of discourse and of talk-in-interaction, the authors use dialogism in the analysis of the members' sensemaking processes. The analysis is based on the theoretical assumption that language and texts are the primary tools actors use to comprehend the social reality and to make sense of their multi-professional discussions. Health care managers are offered insights, derived from theory and empirical evidence, into how professionals' communications influence multi-professional cooperation. The team leader and members are interviewed before and after the observed TC. Team members create their identities and positions in the group by interpreting and "misinterpreting" talk-in-interaction. The analyses reveal the ways the team members relate to their treatment methods in the discussion of a patient; advocating a treatment method means that the team member and the method are intertwined. The findings may be valuable to health care professionals and managers working in teams by showing them how to achieve greater cooperation through the use of verbal abilities. The findings and methods contribute to the international research on cooperation problems in multi-professional teams and to the empirical research on institutional discourse through text and talk.

Tips for leaders, part I: basic principles of leadership.
Harolds, Jay A
2011-08-01
There are many important leadership skills that can be learned from experience, mentoring, reading, discussions, lectures, etc. The subjects include not only business topics and communication skills but also a variety of tips on what to do and what not to do. These include desirable styles of leadership, how to gain the trust of others in the organization, the significance of the appropriate delegation of tasks, the importance of teams, how to manage change, how to win during a crisis, what to do in the early days of becoming a new leader, preventing the loss of one's practice to a rival organization, improving quality, and others. There are also many important attributes of leaders, including having a strong moral compass. Although each of these topics could be a book in of itself, this short series of articles will briefly examine these issues and others.

Carbapenemase-producing Escherichia coli are of major clinical concern. The present study aimed to identify NDM-5 producing E.coli associated with community-acquired urinary tract infection, co-harboring ESBL genes and a pattern of imipenem MIC creep. A total of 973 urine samples were collected from females of age between 18-49 diagnosed with UTI. Isolates were identified by standard microbiological procedures. Presence of bla NDM and ESBL genes was determined by PCR assay and sequencing.PCR based replicon typing was performed. Plasmid stability of all bla producers and their transformants study were analyzed by serial passages and MIC creep phenomenon was analysed by studying revertants. Among 34 bla NDM-5 positive E.coli isolates, 21 isolates co harbored bla CTX-M-15 , followed by multiple combinations of genes. The study revealed diverse types of plasmids type viz; HI1, I1, FIA+FIB, FIA and Y. The strains showed progressive plasmid loss after 31 passages.Twenty-eight isolates mostly had MIC value of 0.5μg/ml and 1μg/ml against imipenem, ertapenem and meropenem. However, on studying the MIC creep activity; the MIC was found elevated from 0.5ug/ml to 64μg/ml and from 1μg/ml to 128μg/ml. While analyzing the revertants, MIC of most of the NDM positive isolates was reduced to 16μg/ml after the 30th serial passages. This study observed a unique phenotype of NDM producers which is not been reported earlier. In the current study, the observed phenomenon poses a global threat as these pathogens may evade phenotypic screening by routine laboratories. Copyright © 2018. Published by Elsevier Ltd.

Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), remains one of the most frequent causes of death worldwide. The slow growth rate of Mtb limits progress toward understanding tuberculosis including diagnosis of infections and evaluating therapeutic efficacy. Development of near-infrared (NIR) β-lactamase (BlaC)-specific fluorogenic substrate has made a significant breakthrough in the whole-animal imaging to detect Mtb infection. The reporter enzyme fluorescence (REF) system using a BlaC-specific fluorogenic substrate has improved the detection sensitivity in whole-animal optical imaging down to ~104 colony forming units (CFU) of bacteria, about 100-fold improvement over recombinant strains. However, improvement of detection sensitivity is strongly needed for clinical diagnosis of early stage infection at greater tissue depth. In order to improve detection sensitivity, we have integrated a fiber-based microendoscpe into a whole-animal imaging system to transmit the excitation light from the fiber bundle to the fluorescent target directly and measure fluorescent level using BlaC-specific REF substrate in the mouse lung. REF substrate, CNIR800, was delivered via aerosol route to the pulmonary infected mice with M. bovis BCG strain at 24 hours post-infection and groups of mice were imaged at 1-4 hours post-administration of the substrate using the integrated imaging system. In this study we evaluated the kinetics of CNIR800 substrate using REF technology using the integrated imaging system. Integration of these technologies has great promise for improved detection sensitivity allowing pre-clinical imaging for evaluation of new therapeutic agents.

Pseudomonas aeruginosa is an opportunistic human pathogen that causes serious problems, especially in people, who have immunodeficiency. In recent times, metallo-β-lactamase (MBLs) resistance in this bacterium has led to some difficulties in treating bacterial infections. The metallo-beta-lactamase family of genes, including blaVIM-1, is being reported with increasing frequency worldwide. The aim of this study is the detection of the metallo-β-lactamase gene blaVIM-1 in imipenem-resistant P. aeruginosa (IRPA) strains isolated from hospitalized patients. In this study, 106 P. aeruginosa samples were isolated from various nosocomial infections. The isolates were identified, tested for susceptibility to various antimicrobial agents by the Kirby-Bauer disk diffusion method, and all the imipenem-resistant isolates were screened for the presence of MBLs by using the combined disk (IMP-EDTA). The minimal inhibitory concentration (MIC) of imipenem was determined by E-test on the Mueller-Hinton agar. To detect the blaVIM-1 gene, the isolates were subjected to a polymerase chain reaction (PCR). Of all the P. aeruginosa isolates, 62 (58.5%) were found to be imipenem-resistant P. aeruginosa (MIC ≥32 μg/ml). Twenty-six (42%) of the imipenem-resistant isolates were MBL positive. None of these isolates carried the blaVIM-1 gene using the PCR assay. The results demonstrated the serious therapeutic threat of the MBL-producing P. aeruginosa populations. The rate of imipenem resistance due to MBL was increased dramatically. Early detection and infection-control practices are the best antimicrobial strategies for this organism. None of MBL-producing isolates in this study carry the blaVIM-1 gene; therefore, another gene in the MBL family should be investigated.

During 2013, ST278 Klebsiella pneumoniae with blaNDM-7 was isolated from the urine (KpN01) and rectum (KpN02) of a patient in Calgary, Canada. The same strain (KpN04) was subsequently isolated from another patient in the same unit. Interestingly, a carbapenem-susceptible K. pneumoniae ST278 (KpN06) was obtained 1 month later from the blood of the second patient. Next-generation sequencing (NGS) revealed that the loss of carbapenem-resistance in KpN06 was due to a 5-kb deletion on the blaNDM-7-harboring IncX3 plasmid. In addition, an IncFIB plasmid in KpN06 had a 27-kb deletion that removed genes encoding for heavy metal resistance. Phylogenetic analysis showed that the K. pneumoniae ST278 from patient 2 was likely a descendant of KpN02 and that KpN06 was a close progenitor of an environmental ST278. It is unclear whether KpN06 lost the blaNDM-7 gene in vivo. This study detailed the remarkable plasticity and speed of evolutionary changes in multidrug-resistant K. pneumoniae, demonstrating the highly recombinant nature of this species. It also highlights the ability of NGS to clarify molecular microevolutionary events within antibiotic-resistant organisms. © The Author 2016.

Making sense of effective partnerships among senior leaders in the National Health Service.
Mitra, Mahima; Hoff, Timothy; Brankin, Paul; Dopson, Sue
2017-05-22
Changing health care systems depend on strong organizational leadership that realizes the collaborative potential of both physician and nonphysician leaders. The aim of this study was to seek insight into the everyday health care leader experience by examining 24 physician and nonphysician leaders working in the U.K. National Health Service. We explored (a) how they make sense of and act with respect to specific collaborative tensions in their interactions and (b) which aspects of their everyday leadership contexts heighten the probability for producing and resolving such tensions. We conducted 24 in-depth interviews with physician and nonphysician leaders in job titles including Chief Operating Officer, Managing Director, Medical Director, and Clinical Director. Ideas from the social psychological perspectives of sensemaking, organizational role theory, and organizational citizenship behavior helped frame the study. We identified four areas of ongoing tension between senior leaders. Each of these was linked to a set of underlying drivers, with the strongest support for drivers with interpersonal roots. Effective strategies for resolving tensions involved significant effort by leaders at improving the interpersonal dynamics associated with everyday interaction and forging relational connections through enhanced trust within the leadership team. This study outlines the organizational and individual characteristics that lend to effective collaboration among senior health care leadership and the types of collaborative tensions likely to be experienced by senior health care leaders. Organizations should provide greater role clarity for senior leadership roles, promote "soft" interpersonal competencies within them, and better assess potential leaders for success in senior roles. Organizational support in the form of facilitation, time, and spaces to learn together can provide a better context for collaborative decision-making.

Amoxicillin-clavulanate resistance (MIC >16 μg/ml) and the corresponding molecular mechanisms were prospectively studied in Escherichia coli over a 3-year period (1996 to 1998) in 14 French hospitals. The overall frequency of resistant E. coli isolates remained stable at about 5% over this period. The highest frequency of resistant isolates (10 to 15%) was observed, independently of the year, among E. coli isolated from lower respiratory tract samples, and the isolation rate of resistant strains was significantly higher in surgical wards than in medical wards in 1998 (7.8 versus 2.8%). The two most frequent mechanisms of resistance for the 3 years were the hyperproduction of the chromosomal class C β-lactamase (48, 38.4, and 39.7%) and the production of inhibitor-resistant TEM (IRT) enzymes (30.4, 37.2, and 41.2%). By using the single-strand conformational polymorphism–PCR technique and sequencing methods, we determined that 59 IRT enzymes corresponded to previously described IRT enzymes whereas 8 were new. Three of these new enzymes derived from TEM-1 by only one amino acid substitution (Ser130Gly, Arg244Gly, and Asn276Asp), whereas three others derived by two amino acid substitutions (Met69Leu and Arg244Ser, Met69Leu and Ile127Val, and Met69Val and Arg275Gln). The two remaining new IRTs showed three amino acid substitutions (Met69Val, Trp165Arg, and Asn276Asp and Met69Ile, Trp165Cys, and Arg275Gln). New genetic features were also found in blaTEM genes, namely, blaTEM-1B with either the promoters Pa and Pb, P4, or a promoter displaying a C→G transversion at position 3 of the −35 consensus sequence and new blaTEM genes, notably one encoding TEM-1 but possessing the silent mutations originally described in blaTEM-2 and then in some blaTEM-encoding IRT enzymes.

2012-10-01
The purpose of this study was to measure RNs' perceptions of teamwork skills and behaviors in their work environment during a multiphase multisite nursing organizational teamwork development initiative. Teamwork is essential for patient safety in healthcare organizations and nursing teams. Organizational development supporting effective teamwork should include a just culture, engaged leadership, and teamwork training. A cross-sectional survey study of bedside RNs was conducted in one 5-hospital healthcare system after a TeamSTEPPS teamwork training initiative. TeamSTEPPS teamwork training related to improved RN perceptions of leadership. Initiatives to align the perspectives and teamwork efforts of leaders and bedside nurses are indicated and should involve charge nurses in the design.

Leader narcissism and follower outcomes: The counterbalancing effect of leader humility.

[Correction Notice: An Erratum for this article was reported in Vol 100(4) of Journal of Applied Psychology (see record 2015-29666-001). The last name of the second author was misspelled in the Online First version of the article. All versions of this article have been corrected.] In response to recent calls to theorize and examine how multiple leader characteristics may work together in their effects, the current research examines how leader narcissism and humility interact to predict perceived leader effectiveness and follower (i.e., direct-report) job engagement and performance. Although an examination of leaders who are narcissistic yet humble may seem oxymoronic and even paradoxical, researchers have suggested that seemingly contradictory personal attributes may exist simultaneously and may actually work together to produce positive outcomes. Results from survey data from followers and leaders working for a large health insurance organization showed that the interaction of leader narcissism and leader humility is associated with perceptions of leader effectiveness, follower job engagement, and subjective and objective follower job performance. Together, these results suggest that narcissistic leaders can have positive effects on followers when their narcissism is tempered by humility. (c) 2015 APA, all rights reserved).

Simulation-based training provides a low-stress learning environment where real-life emergencies can be practiced. Simulation can improve surgical education and patient care in crisis situations through a team approach emphasizing interpersonal and communication skills. This study assessed the effects of simulation-based training in the context of trauma resuscitation in teams of trainees. In a New York State-certified level I trauma center, trauma alerts were assessed by a standardized video review process. Simulation training was provided in various trauma situations followed by a debriefing period. The outcomes measured included the number of healthcare workers involved in the resuscitation, the percentage of healthcare workers in role position, time to intubation, time to intubation from paralysis, time to obtain first imaging study, time to leave trauma bay for computed tomography scan or the operating room, presence of team leader, and presence of spinal stabilization. Thirty cases were video analyzed presimulation and postsimulation training. The two data sets were compared via a 1-sided t test for significance (p < 0.05). Nominal data were analyzed using the Fischer exact test. The data were compared presimulation and postsimulation. The number of healthcare workers involved in the resuscitation decreased from 8.5 to 5.7 postsimulation (p < 0.001). The percentage of people in role positions increased from 57.8% to 83.6% (p = 0.46). The time to intubation from paralysis decreased from 3.9 to 2.8 minutes (p < 0.05). The presence of a definitive team leader increased from 64% to 90% (p < 0.05). The rate of spine stabilization increased from 82% to 100% (p < 0.08). After simulation, training adherence to the advanced trauma life support algorithm improved from 56% to 83%. High-stress situations simulated in a low-stress environment can improve team interaction and educational competencies. Providing simulation training as a tool for surgical education may

Managing diversity and enhancing team outcomes: the promise of transformational leadership.
Kearney, Eric; Gebert, Diether
2009-01-01
In a sample of 62 research and development (R&D) teams, the authors examined transformational leadership as a moderator of the relationship of age, nationality, and educational background diversity with team outcomes. When levels of transformational leadership were high, nationality and educational diversity were positively related to team leaders' longitudinal ratings of team performance. These relationships were nonsignificant when transformational leadership was low. Age diversity was not related to team performance when transformational leadership was high, and it was negatively related to team performance when transformational leadership was low. Two mediated moderation effects help explain these findings. Transformational leadership moderated the relationship of the 3 examined diversity dimensions with the elaboration of task-relevant information, which in turn was positively associated with team performance. Moreover, transformational leadership moderated the relationship of the 3 diversity types with collective team identification, which in turn was positively related to the elaboration of task-relevant information. The authors discuss the theoretical and practical implications of these results. Overall, this study suggests that transformational leadership can foster the utilization of the potential, but frequently untapped, benefits entailed by both demographic and informational/cognitive team diversity.

The usefulness of carbapenems for gram-negative infections is becoming compromised by organisms harboring carbapenemases, enzymes which can hydrolyze the drug. Currently KPC (class A), NDM (class B), and OXA-48 types (class D) are the most globally widespread carbapenemases. However, among the GES-type class A extended-spectrum β-lactamases (ESBLs) there are variants that hydrolyze carbapenems, with blaGES-5 being the most common. Two Escherichia coli and two Serratia marcescens harboring blaGES-5 on plasmids were isolated by the Canadian Nosocomial Infection Surveillance Program (CNISP) from four different patients in a single hospital over a 2-year period. Complete sequencing of the blaGES-5 plasmids indicated that all four had nearly identical backbones consisting of genes for replication, partitioning, and stability, but contained variant accessory regions consisting of mobile elements and antimicrobial resistance genes. The plasmids were of a novel replicon type, but belonged to the MOBQ1 group based on relaxase sequences, and appeared to be mobilizable, but not self-transmissible. Considering the time periods of bacterial isolation, it would appear the blaGES-5 plasmid has persisted in an environmental niche for at least 2 years in the hospital. This has implications for infection control and clinical care when it is transferred to clinically relevant gram-negative organisms.

ABSTRACT The emergence of pan-resistant Klebsiella pneumoniae strains is an increasing concern. In the present study, we describe a cluster of 9 pan-resistant K. pneumoniae sequence type 147 (ST147) isolates encountered in 4 patients over nearly 1 year in 3 hospitals of the United Arab Emirates (UAE). The isolates exhibited highly similar genotypes. All produced chromosomally encoded OXA-181, and the majority also produced the NDM-5 carbapenemase. As with the previously described single isolate from the UAE, MS6671, the mgrB was disrupted by a functional, ISEcp1-driven blaOXA-181 insertion causing resistance to carbapenems. The mutation was successfully complemented with an intact mgrB gene, indicating that it was responsible for colistin resistance. blaNDM-5 was located within a resistance island of an approximately 100-kb IncFII plasmid carrying ermB, mph(A), blaTEM-1B, rmtB, blaNDM-5, sul1, aadA2, and dfrA12 resistance genes. Sequencing this plasmid (pABC143-NDM) revealed that its backbone was nearly identical to that of plasmid pMS6671E from which several resistance genes, including blaNDM-5, had been deleted. More extensive similarities of the backbone and the resistance island were found between pABC143C-NDM and the blaNDM-5-carrying IncFII plasmids of two K. pneumoniae ST147 isolates from South Korea, one of which was colistin resistant, and both also produced OXA-181. Notably, one of these strains was isolated from a patient transferred from the UAE. Our data show that this pan-resistant clone has an alarming capacity to maintain itself over an extended period of time and is even likely to be transmitted internationally. PMID:28438945

Students' Understanding and Perceptions of Assigned Team Roles in a Classroom Laboratory Environment
Ott, Laura E.; Kephart, Kerrie; Stolle-McAllister, Kathleen; LaCourse, William R.
2018-01-01
Using a cooperative learning framework in a quantitative reasoning laboratory course, students were assigned to static teams of four in which they adopted roles that rotated regularly. The roles included: team leader, protocol manager, data recorder, and researcher. Using a mixed-methods approach, we investigated students' perceptions of the team roles and specifically addressed students' understanding of the roles, students' beliefs in their ability to enact the roles, and whether working with assigned team roles supported the teams to work effectively and cohesively. Although students expressed confidence in their understanding of the team roles, their understanding differed from the initial descriptions. This suggests that students' understanding of team roles may be influenced by a variety of factors, including their experiences within their teams. Students also reported that some roles appeared to lack a purpose, implying that for roles to be successful, they must have a clear purpose. Finally, the fact that many students reported ignoring the team roles suggests that students do not perceive roles as a requirement for team productivity and cohesion. On the basis of these findings, we provide recommendations for instructors wishing to establish a classroom group laboratory environment. PMID:29681667

Divide and rule: A qualitative analysis of the debriefing process in elite team sports.
Macquet, A-C; Ferrand, C; Stanton, N A
2015-11-01
This article aimed to gain an understanding of the process of debriefing during major competitions in elite team sports. Debrief interviews were conducted with 9 head coaches. The interview data were used to identify how head coaches divided up the tasks given to staff and team members prior to, and during the post-match debriefing. Results showed that debriefing consisted of two steps: preparation and presentation. Preparation referred to four successive tasks. Presentation to the team of players consisted of eight tasks relating to transformational and transactional styles of leadership. Coaches were shown to divide the labor within the staff and team. The data tend to support the view that in elite team sports, coaches are both transformational and transactional leaders, adapting their style of leadership to the situation, athletes and time available. This study provides insights into the task-work and team-work underlying team functioning and division of labor. Copyright © 2015 Elsevier Ltd and The Ergonomics Society. All rights reserved.

Nursing in the mirror: unveiling transpersonal leadership in team care.
Nunes, Emanuelle Caires Dias Araújo; Muniz, Edla Lobo
2017-02-23
The aim of this paper was to reveal the individual nurse in the leadership process for transpersonal care of the nursing team. This is a descriptive-exploratory and qualitative study grounded in Transpersonal Care provided at the General Hospital in Vitória da Conquista, Bahia, with 10 nurses who coordinated services at the unit in 2013. Data were collected using a mirror and semi-structured interviews subjected to thematic analysis. The following three categories emerged: Leadership in nursing: potentialities and barriers that permeate intersubjectivity; Transpersonal care of the leader with the team; and transpersonal leadership on balance: critical nodes. The final reflections revealed the individual nurse in the leadership process for transpersonal care of the nursing team, and stress the need to provide institutional and educational support that can help develop the servant and transpersonal skills of the leading nurse.

Moving the Science of Team Science Forward: Collaboration and Creativity
Hall, Kara L.; Feng, Annie X.; Moser, Richard P.; Stokols, Daniel; Taylor, Brandie K.
2012-01-01
Teams of scientists representing diverse disciplines are often brought together for purposes of better understanding and, ultimately, resolving urgent public health and environmental problems. Likewise, the emerging field of the science of team science draws on diverse disciplinary perspectives to better understand and enhance the processes and outcomes of scientific collaboration. In this supplement to the American Journal of Preventive Medicine, leading scholars in the nascent field of team science have come together with a common goal of advancing the field with new models, methods, and measures. This summary article highlights key themes reflected in the supplement and identifies several promising directions for future research organized around the following broad challenges: (1) operationalizing cross-disciplinary team science and training more clearly; (2) conceptualizing the multiple dimensions of readiness for team science; (3) ensuring the sustainability of transdisciplinary team science; (4) developing more effective models and strategies for training transdisciplinary scientists; (5) creating and validating improved models, methods, and measures for evaluating team science; and (6) fostering transdisciplinary cross-sector partnerships. A call to action is made to leaders from the research, funding, and practice sectors to embrace strategies of creativity and innovation in a collective effort to move the field forward, which may not only advance the science of team science but, ultimately, public health science and practice.

What are the traits of successful leaders and can they be applied to those of us in health care? Leaders must deal with conflict to get a group of people to move in the same direction. Successful leaders learn to have difficult conversations that increase understanding and morale and creatively deal with the inevitable interpersonal conflicts present in every organization made up of people. Another useful trait for a leader during uncertain and chaotic times is the ability to see things as they really are, rather than as we wish or believe them to be. Successful leaders are also usually optimists who level with their co-workers.

Although narcissists often emerge as leaders, research has thus far shown inconsistent results on the relationship between leader narcissism and effectiveness in the eyes of followers. Here we draw on leader distance theory (Shamir, 1995) and implicit leader theory (Lord & Maher, 1991) to propose that followers' assessment of a narcissistic leader and followers' overall job attitudes depend on the leader's visibility to the followers. The more opportunities followers have to observe narcissistic leaders the more they will experience these leaders' toxic behavior (e.g., exploitativeness) and the less they will perceive the leader as effective. To test our hypotheses we collected multisource, longitudinal data from 175 retail stores and obtained subjective (followers' perceptions of leader effectiveness and their overall job attitudes) as well as objective (leaders' organizational experience at time of hire, employee absenteeism trends) indices of leader functionality. Results showed that narcissistic leaders had less organizational experience at the time they were hired. Moreover, when followers had fewer opportunities to observe their leader, leader narcissism was positively related to perceived leadership effectiveness and job attitudes. However, when followers had more opportunity to observe their leader, the positive relationship disappeared. Finally, leader narcissism was neither positively nor negatively associated with absenteeism, whereas absenteeism declined over time under non-narcissistic leaders. These findings advance our knowledge of how followers respond to narcissistic leaders and how these leaders function in organizational settings where they have legitimate positions of power.

Performance improvement in a complex health care environment depends on the cooperation of diverse individuals and groups, allocation of time and resources, and use of effective improvement methods. To address this challenge, we developed an 18-week multidisciplinary training program that would also provide a vehicle for effecting needed improvements, by using a team- and project-based model. The program began in the radiology department and subsequently expanded to include projects from throughout the medical center. Participants were taught a specific method for team-based problem solving, which included (a) articulating the problem, (b) observing the process, (c) analyzing possible causes of problems, (d) identifying key drivers, (e) testing and refining interventions, and (f) providing for sustainment of results. Progress was formally reviewed on a weekly basis. A total of 14 teams consisting of 78 participants completed the course in two cohorts; one project was discontinued. All completed projects resulted in at least modest improvement. Mean skill scores increased from 2.5/6 to 4.5/6 (P < .01), and the mean satisfaction score was 4.7/5. Identified keys to success include (a) engagement of frontline staff, (b) teams given authority to make process changes, (c) capable improvement coaches, (d) a physician-director with improvement expertise and organizational authority, (e) capable administrative direction, (f) supportive organizational leaders, (g) weekly progress reviews, (h) timely educational material, (i) structured problem-solving methods, and ( j ) multiple projects working simultaneously. The purpose of this article is to review the program, including the methods and results, and discuss perceived keys to program success. © RSNA, 2016.

Team-based primary care: The medical assistant perspective.
Sheridan, Bethany; Chien, Alyna T; Peters, Antoinette S; Rosenthal, Meredith B; Brooks, Joanna Veazey; Singer, Sara J
Team-based care has the potential to improve primary care quality and efficiency. In this model, medical assistants (MAs) take a more central role in patient care and population health management. MAs' traditionally low status may give them a unique view on changing organizational dynamics and teamwork. However, little empirical work exists on how team-based organizational designs affect the experiences of low-status health care workers like MAs. The aim of this study was to describe how team-based primary care affects the experiences of MAs. A secondary aim was to explore variation in these experiences. In late 2014, the authors interviewed 30 MAs from nine primary care practices transitioning to team-based care. Interviews addressed job responsibilities, teamwork, implementation, job satisfaction, and learning. Data were analyzed using a thematic networks approach. Interviews also included closed-ended questions about workload and job satisfaction. Most MAs reported both a higher workload (73%) and a greater job satisfaction (86%) under team-based primary care. Interview data surfaced four mechanisms for these results, which suggested more fulfilling work and greater respect for the MA role: (a) relationships with colleagues, (b) involvement with patients, (c) sense of control, and (d) sense of efficacy. Facilitators and barriers to these positive changes also emerged. Team-based care can provide low-status health care workers with more fulfilling work and strengthen relationships across status lines. The extent of this positive impact may depend on supporting factors at the organization, team, and individual worker levels. To maximize the benefits of team-based care, primary care leaders should recognize the larger role that MAs play under this model and support them as increasingly valuable team members. Contingent on organizational conditions, practices may find MAs who are willing to manage the increased workload that often accompanies team-based care.

Enterobacter hormaechei and Cronobacter sakazakii are amongst the most important causes of outbreaks of neonatal sepsis associated with powdered milk. In this study, we report for the first time an outbreak of a novel Enterobacter sp. harbouring bla(CTX-M-15) in a neonatal unit in Tanzania. Seventeen Gram-negative enteric isolates from neonatal blood cultures were studied. Antibiotic susceptibility was assessed by disc diffusion testing, and the presence of the bla(CTX-M-15) gene was established by polymerase chain reaction (PCR) and sequencing. Isolates were typed by pulsed-field gel electrophoresis (PFGE). Identification by biochemical profiling was followed by nucleotide sequencing of 16S ribosomal DNA (rDNA), rpoB and hsp60 alleles. Environmental sampling was done and control measures were established. Isolates were initially misidentified based on their fermentation characteristics and agglutination as Salmonella enterica serotype Paratyphi. All isolates were resistant to multiple antibiotics, except for ciprofloxacin and carbapenems, and were found to harbour bla(CTX-M-15) on a 291-kb narrow-range plasmid. PFGE analysis indicated the clonal outbreak of a single strain, infecting 17 neonates with a case fatality rate of 35%. The same strain was isolated from a milk bucket. Phylogenetic analysis using 16S rDNA, rpoB and hsp60 sequences permitted no definitive identification, clustering the strains in the Enterobacter cloacae complex with similarities of 92-98.8%. The data describe an outbreak of a novel bla(CTX-M-15)-positive, multiresistant Enterobacter strain in an African neonatal unit that can easily be misidentified taxonomically. These data highlight the need for constant surveillance of bacteria harbouring extended-spectrum β-lactamases as well as improvements in hygiene measures in developing countries.

Rapid detection of blaKPC-containing organisms can significantly impact infection control and clinical practices, as well as therapeutic choices. Current molecular and phenotypic methods to detect these organisms, however, require additional testing beyond routine organism identification. In this study, we evaluated the clinical performance of matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS) to detect pKpQIL_p019 (p019)—an ∼11,109-Da protein associated with certain blaKPC-containing plasmids that was previously shown to successfully track a clonal outbreak of blaKPC-pKpQIL-Klebsiella pneumoniae in a proof-of-principle study (A. F. Lau, H. Wang, R. A. Weingarten, S. K. Drake, A. F. Suffredini, M. K. Garfield, Y. Chen, M. Gucek, J. H. Youn, F. Stock, H. Tso, J. DeLeo, J. J. Cimino, K. M. Frank, and J. P. Dekker, J Clin Microbiol 52:2804–2812, 2014, http://dx.doi.org/10.1128/JCM.00694-14). PCR for the p019 gene was used as the reference method. Here, blind analysis of 140 characterized Enterobacteriaceae isolates using two protein extraction methods (plate extraction and tube extraction) and two peak detection methods (manual and automated) showed sensitivities and specificities ranging from 96% to 100% and from 95% to 100%, respectively (2,520 spectra analyzed). Feasible laboratory implementation methods (plate extraction and automated analysis) demonstrated 96% sensitivity and 99% specificity. All p019-positive isolates (n = 26) contained blaKPC and were carbapenem resistant. Retrospective analysis of an additional 720 clinical Enterobacteriaceae spectra found an ∼11,109-Da signal in nine spectra (1.3%), including seven from p019-containing, carbapenem-resistant isolates (positive predictive value [PPV], 78%). Instrument tuning had a significant effect on assay sensitivity, highlighting important factors that must be considered as MALDI-TOF MS moves into applications beyond microbial identification.

Conflict on interprofessional primary health care teams--can it be resolved?
Brown, Judith; Lewis, Laura; Ellis, Kathy; Stewart, Moira; Freeman, Thomas R; Kasperski, M Janet
2011-01-01
Increasingly, primary health care teams (PHCTs) depend on the contributions of multiple professionals. However, conflict is inevitable on teams. This article examines PHCTs members' experiences with conflict and responses to conflict. This phenomenological study was conducted using in-depth interviews with 121 participants from 16 PHCTs (10 urban and 6 rural) including a wide range of health care professionals. An iterative analysis process was used to examine the verbatim transcripts. The analysis revealed three main themes: sources of team conflict; barriers to conflict resolution; and strategies for conflict resolution. Sources of team conflict included: role boundary issues; scope of practice; and accountability. Barriers to conflict resolution were: lack of time and workload; people in less powerful positions; lack of recognition or motivation to address conflict; and avoiding confrontation for fear of causing emotional discomfort. Team strategies for conflict resolution included interventions by team leaders and the development of conflict management protocols. Individual strategies included: open and direct communication; a willingness to find solutions; showing respect; and humility. Conflict is inherent in teamwork. However, understanding the potential barriers to conflict resolution can assist PHCTs in developing strategies to resolve conflict in a timely fashion.

Performance Under Stress Conditions During Multidisciplinary Team Immersive Pediatric Simulations.
Ghazali, Daniel Aiham; Darmian-Rafei, Ivan; Ragot, Stéphanie; Oriot, Denis
2018-06-01
The primary objective was to determine whether technical and nontechnical performances were in some way correlated during immersive simulation. Performance was measured among French Emergency Medical Service workers at an individual and a team level. Secondary objectives were to assess stress response through collection of physiologic markers (salivary cortisol, heart rate, the proportion derived by dividing the number of interval differences of successive normal-to-normal intervals > 50 ms by the total number of normal-to-normal intervals [pNN50], low- and high-frequency ratio) and affective data (self-reported stress, confidence, and dissatisfaction), and to correlate them to performance scores. Prospective observational study performed as part of a larger randomized controlled trial. Medical simulation laboratory. Forty-eight participants distributed among 12 Emergency Medical System teams. Individual and team performance measures and individual stress response were assessed during a high-fidelity simulation. Technical performance was assessed by the intraosseous access performance scale and the Team Average Performance Assessment Scale; nontechnical performance by the Behavioral Assessment Tool for leaders, and the Clinical Teamwork Scale. Stress markers (salivary cortisol, heart rate, pNN50, low- and high-frequency ratio) were measured both before (T1) and after the session (T2). Participants self-reported stress before and during the simulation, self-confidence, and perception of dissatisfaction with team performance, rated on a scale from 0 to 10. Scores (out of 100 total points, mean ± SD) were intraosseous equals to 65.6 ± 14.4, Team Average Performance Assessment Scale equals to 44.6 ± 18.1, Behavioral Assessment Tool equals to 49.5 ± 22.0, Clinical Teamwork Scale equals to 50.3 ± 18.5. There was a strong correlation between Behavioral Assessment Tool and Clinical Teamwork Scale (Rho = 0.97; p = 0.001), and Behavioral Assessment

This study aims to explore the relationship between team-leadership skills and quality of cardiopulmonary resuscitation in an adult cardiac-arrest simulation. Factors affecting team-leadership skills were also assessed. Forty advanced life-support providers leading a cardiac arrest team in a standardized cardiac-arrest simulation were videotaped. Background data were collected, including age (in yrs), sex, whether they had received any leadership training in the past, whether they were part of a professional group, the most recent advanced life-support course (in months) they had undergone, advanced life-support instructor/provider status, and whether they had led in any cardiac arrest situation in the preceding 6 months. Participants were scored using the Cardiac Arrest Simulation test score and Leadership Behavior Description Questionnaire for leadership skills. Process-focused quality of cardiopulmonary resuscitation data were collected directly from manikin and video recordings. Primary outcomes were complex technical skills (measured as Cardiac Arrest Simulation test score, preshock pause, and hands-off ratio). Secondary outcomes were simple technical skills (chest-compression rate, depth, and ventilation rate). Univariate linear regressions were performed to examine how leadership skills affect quality of cardiopulmonary resuscitation and bivariate correlations elicited factors affecting team-leadership skills.Teams led by leaders with the best leadership skills performed higher quality cardiopulmonary resuscitation with better technical performance (R = 0.75, p < .001), shorter preshock pauses (R = 0.18, p < .001), with lower total hands-off ratio (R = 0.24, p = .01), and shorter time to first shock (R = 0.14, p = .02). Leadership skills were not significantly associated with more simple technical skills such as chest-compression rate, depth, and ventilation rate. Prior training in team leader skills was independently associated with better leadership

Vibrio parahaemolyticus is an important causative agent of gastroenteritis, with the consumption of contaminated seafood being the major transmission route. Resistance to penicillin is common among V. parahaemolyticus strains, whereas cephalosporin resistance remains rare. In an attempt to assess the current prevalence and characteristics of antibiotic resistance of this pathogen in common food samples, a total of 54 (17% of the total samples) V. parahaemolyticus strains were isolated from 318 meat and seafood samples purchased from supermarkets and wet markets in Shenzhen, China, in 2013. These isolates exhibited high-level resistance to ampicillin, yet they were mostly susceptible to other antimicrobials, except for two that were resistant to extended-spectrum cephalosporins. The β-lactamase gene blaPER-1 was detectable in one strain, V. parahaemolyticus V43, which was resistant to both third- and fourth-generation cephalosporins. Compared to other blaPER-1-positive V. parahaemolyticus strains reported in our previous studies, strain V43 was found to harbor an ∼200-kb conjugative plasmid carrying genes that were different from the antimicrobial resistance genes reported from the previous studies. The β-lactamase gene blaCMY-2 was detectable for the first time in another V. parahaemolyticus isolate, V4, which was resistant to third-generation cephalosporins. This blaCMY-2 gene was shown to be located in an ∼150-kb IncA/C-type conjugative plasmid with a genetic structure consisting of traB-traV-traA-ISEcp1-blaCMY-2-blc-sugE-encR-orf1-orf2-orf3-orf4-dsbC-traC, which is identical to that of other IncA/C conjugative plasmids in Enterobacteriaceae, albeit with a different size. These findings indicate that the transmission of extended-spectrum-β-lactamase (ESBL) and AmpC β-lactamase genes via conjugative plasmids can mediate the development of extended-spectrum cephalosporin resistance in V. parahaemolyticus, thereby posing a potential threat to public health

Are Empowered Employees More Proactive? The Contingency of How They Evaluate Their Leader.
Yin, Kui; Xing, Lu; Li, Can; Guo, Yungui
2017-01-01
Finding ways to enhance employee proactive behavior is a focal concern for academics and practitioners. Previous studies have found a positive association between empowering leadership and proactive behavior (Martin et al., 2013; Li et al., 2017). However, these studies lack elaboration on mechanisms and do not rule out the effect of employees' proactive personality during empirical testing. We investigate empowering leadership from individual perspective due to the variation of empowerment levels even in the same team. Our research proposes a more elaborated theoretical model that explains why, and when, empowering leadership might promote employee proactive behavior. Specifically, we examine mediating mechanisms based on social cognitive theory and propose trust in leader competency as boundary condition. Using a sample of 280 leader-follower dyads from a large state-owned Chinese company, our results revealed that (1) empowering leadership was positively related to proactive behavior, with role breadth self-efficacy acting as a mediator for this relationship; (2) employees' trust in leader competency moderated both the empowering leadership-subordinate proactive behavior relationship and the mediating effect of role breadth self-efficacy, such that the empowering leadership-subordinate proactive behavior relationship was weaker, and the mediating effect of role breadth self-efficacy was stronger, for employees with high levels of trust in leader competency.

Bringing new therapies to patients with rare diseases depends in part on optimizing clinical trial conduct through efficient study start-up processes and rapid enrollment. Suboptimal execution of clinical trials in academic medical centers not only results in high cost to institutions and sponsors, but also delays the availability of new therapies. Addressing the factors that contribute to poor outcomes requires novel, systematic approaches tailored to the institution and disease under study. To use clinical trial performance metrics data analysis to select high-performing cystic fibrosis (CF) clinical research teams and then identify factors contributing to their success. Mixed-methods research, including semi-structured qualitative interviews of high-performing research teams. CF research teams at nine clinical centers from the CF Foundation Therapeutics Development Network. Survey of site characteristics, direct observation of team meetings and facilities, and semi-structured interviews with clinical research team members and institutional program managers and leaders in clinical research. Critical success factors noted at all nine high-performing centers were: 1) strong leadership, 2) established and effective communication within the research team and with the clinical care team, and 3) adequate staff. Other frequent characteristics included a mature culture of research, customer service orientation in interactions with study participants, shared efficient processes, continuous process improvement activities, and a businesslike approach to clinical research. Clinical research metrics allowed identification of high-performing clinical research teams. Site visits identified several critical factors leading to highly successful teams that may help other clinical research teams improve clinical trial performance.

Communication and relationship skills for rapid response teams at hamilton health sciences.
Cziraki, Karen; Lucas, Janie; Rogers, Toni; Page, Laura; Zimmerman, Rosanne; Hauer, Lois Ann; Daniels, Charlotte; Gregoroff, Susan
2008-01-01
Rapid response teams (RRT) are an important safety strategy in the prevention of deaths in patients who are progressively failing outside of the intensive care unit. The goal is to intervene before a critical event occurs. Effective teamwork and communication skills are frequently cited as critical success factors in the implementation of these teams. However, there is very little literature that clearly provides an education strategy for the development of these skills. Training in simulation labs offers an opportunity to assess and build on current team skills; however, this approach does not address how to meet the gaps in team communication and relationship skill management. At Hamilton Health Sciences (HHS) a two-day program was developed in collaboration with the RRT Team Leads, Organizational Effectiveness and Patient Safety Leaders. Participants reflected on their conflict management styles and considered how their personality traits may contribute to team function. Communication and relationship theories were reviewed and applied in simulated sessions in the relative safety of off-site team sessions. The overwhelming positive response to this training has been demonstrated in the incredible success of these teams from the perspective of the satisfaction surveys of the care units that call the team, and in the multi-phased team evaluation of their application to practice. These sessions offer a useful approach to the development of the soft skills required for successful RRT implementation.

[Development of a scale to measure leadership capacity of players in sports teams].
Arce, Constantino; Torrado, Julio; Andrade, Elena; Garrido, Javier; de Francisco, Cristina
2008-11-01
This study describes the process of developing a scale to measure the leadership capacity of players in sports teams. Research into sports leadership has focused almost exclusively on the formal leadership of the coach, in which the studies by Chelladurai, with his five-factor model, have become an essential point of reference. Nevertheless, hardly any research has been carried out into the leadership that certain players exercise over the other team members. For this purpose, a sample of 143 male basketball players was used; these participants were asked to evaluate the characteristics of the sports leader over a total of 54 indicators. Firstly, explanatory factor analysis was performed with participants' responses, using principal axis and oblique rotation methods. The factor structure obtained was then subjected to confirmatory factorial analysis, enabling us to propose a Sports Leader Evaluation Scale (EELD, in Spanish) with 18 items grouped into 3 factors, denominated empathy and responsibility, assertiveness, and impulsiveness. Satisfactory fit indices were obtained for the model, for the reliability of items and for the internal consistency of factors.

In 2 studies, this research demonstrated the existence of leader transference, a cognitive process whereby mental representations of previous leaders are activated and used for evaluation when new, similar leaders are encountered. The 1st study demonstrated that exposure to a new leader who was similar to a past leader led to erroneous generalization of leader characteristics and associated underlying attributions. The 2nd study showed that expectations of just treatment and abuse were also subject to transfer from old to new, similar leaders, although positive and negative affective responses were not. Results suggested that individuals exposed to a leader who was not reminiscent of an old leader were more likely to use a general leader prototype to form leader expectations, whereas individuals exposed to a leader who was similar to an old leader activated a significant other mental representation for use in making judgments. These results have implications for individual- and relational-level processes as characterized by implicit leadership theory and leader-member exchange theory as well as macro theories of leader succession and organizational culture change.

Leader-member exchange (LMX) and innovation climate: the role of LMX differentiation.
Tordera, Núria; González-Romá, Vicente
2013-01-01
Leader-member Exchange (LMX) theory has been shown to be one of the most compelling theories for understanding the effects of leadership on organizational behavior. This theory proposes that leaders establish differentiated relationships with each of their subordinates according to the exchanges produced between them. Recently, the concept of LMX differentiation has been introduced into the theory to extend research from the dyadic to the group level. The present paper uses a longitudinal design to analyze the moderator role of LMX differentiation in the relationship between mean LMX and innovation climate in a sample of 24 healthcare teams. The results showed no direct effects of mean LMX on changes in innovation climate over time. However, they provide support for the moderator effect of LMX differentiation in this relationship, as it was stronger when LMX differentiation was low than when it was high.

2005-01-01
Cancer support groups are an important source of support for cancer patients, yet little is known about the characteristics of, and barriers to, effective leadership, and the training needs of both professionally trained and untrained leaders. This study explored the views of 179 leaders of 184 cancer support groups in NSW, Australia, regarding these issues. Four hundred and sixteen members of 50 groups selected from the larger cohort completed questionnaires eliciting the importance of group processes, including leader qualities, and satisfaction with group leadership. Finally, members of nine groups participated in focus groups regarding effective group processes. The importance of the leader(s) was emphasized in all stages of the research. Fifty-nine percent of group leaders were currently experiencing a difficulty, primarily related to infrastructure or group process. Three characteristics of effective leaders were identified: educational qualities, facilitation skills, and personal qualities. There is clearly a need to develop and evaluate effective interventions to maintain leaders in these roles, if the proven benefits for cancer patients are to be protected.

Changes in the way organizations are structured and advances in communication technologies are two factors that have altered the conditions under which group decisions are made. Decisions are increasingly made by teams that have a hierarchical structure and whose members have different areas of expertise. In addition, many decisions are no longer made via strictly face-to-face interaction. The present study examines the effects of two modes of communication (face-to-face or computer-mediated) on the accuracy of teams' decisions. The teams are characterized by a hierarchical structure and their members differ in expertise consistent with the framework outlined in the Multilevel Theory of team decision making presented by Hollenbeck, Ilgen, Sego, Hedlund, Major, and Phillips (1995). Sixty-four four-person teams worked for 3 h on a computer simulation interacting either face-to-face (FtF) or over a computer network. The communication mode had mixed effects on team processes in that members of FtF teams were better informed and made recommendations that were more predictive of the correct team decision, but leaders of CM teams were better able to differentiate staff members on the quality of their decisions. Controlling for the negative impact of FtF communication on staff member differentiation increased the beneficial effect of the FtF mode on overall decision making accuracy.

Demand for palliative care services in Canada will increase owing to an aging population and the evolving role of palliative care in non-malignant illness. Increasing healthcare demands continue to shape the clinical nurse specialist (CNS) role, especially in the area of palliative care. Clinical nurse specialists bring specialized knowledge, skills and leadership to the clinical setting to enhance patient and family care. This paper highlights the clinical leadership role of the CNS as triage leader for a hospital-based palliative care consulting team. Changes to the team's referral and triage processes are emphasized as key improvements to team efficiency and timely access to care for patients and families.

Increasing evidence shows that active sites of proteins have non-trivial conformational dynamics. These dynamics include active site residues sampling different local conformations that allow for multiple, and possibly novel, inhibitor binding poses. Yet, active site dynamics garner only marginal attention in most inhibitor design efforts and exert little influence on synthesis strategies. This is partly because synthesis requires a level of atomic structural detail that is frequently missing in current characterizations of conformational dynamics. In particular, while the identity of the mobile protein residues may be clear, the specific conformations they sample remain obscure. Here, we show how an appropriate choice of ligand can significantly sharpen our abilities to describe the interconverting binding poses (conformations) of protein active sites. Specifically, we show how 2-(2'-carboxyphenyl)-benzoyl-6-aminopenicillanic acid (CBAP) exposes otherwise hidden dynamics of a protein active site that binds β-lactam antibiotics. When CBAP acylates (binds) the active site serine of the β-lactam sensor domain of BlaR1 (BlaRS), it shifts the time scale of the active site dynamics to the slow exchange regime. Slow exchange enables direct characterization of inter-converting protein and bound ligand conformations using NMR methods. These methods include chemical shift analysis, 2-d exchange spectroscopy, off-resonance ROESY of the bound ligand, and reduced spectral density mapping. The active site architecture of BlaRS is shared by many β-lactamases of therapeutic interest, suggesting CBAP could expose functional motions in other β-lactam binding proteins. More broadly, CBAP highlights the utility of identifying chemical probes common to structurally homologous proteins to better expose functional motions of active sites.

Research describes leadership as important to guideline use. Yet interventions to develop current and future leaders for this purpose are not well understood. To describe the planning and evaluation of a leadership intervention to facilitate nurses' use of guideline recommendations for diabetic foot ulcers in home health care. Planning the intervention involved a synthesis of theory and research (qualitative interviews and chart audits). One workshop and three follow-up teleconferences were delivered at two sites to nurse managers and clinical leaders (n=15) responsible for 180 staff nurses. Evaluation involved workshop surveys and interviews. Highest rated intervention components (four-point scale) were: identification of target indicators (mean 3.7), and development of a team leadership action plan (mean 3.5). Pre-workshop barriers assessment rated lowest (mean 2.9). Three months later participants indicated their leadership performance had changed as a result of the intervention, being more engaged with staff and clear about implementation goals. Creating a team leadership action plan to operationalize leadership behaviours can help in delivery of evidence-informed care. Access to clinical data and understanding team leadership knowledge and skills prior to formal training will assist nursing management in tailoring intervention strategies to identify needs and gaps. © 2010 The Authors.

To describe how actions of nursing unit leaders influenced the long-term sustainability of a best practice guidelines (BPG) program on inpatient units. Several factors influence the initial implementation of evidence-based practice improvements in nursing, with leadership recognized as essential. However, there is limited knowledge about enduring change, including how frontline nursing leaders influence the sustainability of practice improvements over the long term. A qualitative descriptive case study included 39 in-depth interviews, observations, and document reviews. Four embedded nursing unit subcases had differing levels of program sustainability at 7 years (average) following implementation. Higher levels of BPG sustainability occurred on units where formal leadership teams used an integrated set of strategies and activities. Two key strategies were maintaining priorities and reinforcing expectations. The coordinated use of six activities (e.g., discussing, evaluating, integrating) promoted the continuation of BPG practices among staff. These leadership processes, fostering exchange and learning, contributed to sustainability-promoting environments characterized by teamwork and accountability. Unit leaders are required to strategically orchestrate several overlapping and synergistic efforts to achieve long-term sustainability of BPG-based practice improvements. As part of managing overall unit performance, unit leaders may influence practice improvement sustainability by aligning vision, strategies, and activities. © 2015 John Wiley & Sons Ltd.

To analyse nursing turnover intention from the unit by using multilevel approach, examining at the individual level, the relationships between job characteristics, job satisfaction and turnover intention, and at the group level the role of leader-member exchange. Research on nursing turnover has given little attention to the effects of multilevel factors. Aggregated data of 935 nurses nested within 74 teams of four Italian hospitals were collected in 2009 via a self-administered questionnaire. Hierarchical linear modelling showed that job satisfaction mediated the relationship between job characteristics and intention to leave at the individual level. At the unit level, leader-member exchange was directly linked to intention to leave. Furthermore, cross-level interaction revealed that leader-member exchange moderated the relationship between job characteristics and job satisfaction. This study supported previous research in single-level turnover studies concerning the key role of job satisfaction, providing evidence that job characteristics are important in creating motivating and satisfying jobs. At the unit-level, leader-member exchange offers an approach to understand the role of unit-specific conditions created by leaders on nurses' workplace wellbeing. This study showed that it is important for nursing managers to recognise the relevance of implementing management practices that foster healthy workplaces centred on high-quality nurse-supervisor relationships. © 2014 John Wiley & Sons Ltd.

The objective of this study was to genetically characterize the antimicrobial resistance mechanisms of Salmonella enterica serotype Indiana C629 isolated from a chicken carcass in China in 2014. Antimicrobial susceptibility against a panel of 23 antimicrobial agents was carried out on Salmonella enterica serotype Indiana C629 and assessed according to CLSI standards. Whole-genome sequencing of this isolate was conducted to obtain the complete genome of S. Indiana. Salmonella Indiana C629 expressed an XDR phenotype being resistant to more than 20 antimicrobial agents, including imipenem and meropenem. From the analysis of the resistance mechanisms, two mutations were identified in subunit A of DNA gyrase within the quinolone resistance determining region, in addition to the acquisition of mobile efflux pumps encoding oqxA/B/R. Additionally, four beta-lactamases resistance genes (bla CTX-M-65 , bla TEM-1 , bla OXA-1 , and bla NDM-1 ), five aminoglycosides resistance genes (aac(3)-IV, aac(6')-Ib-cr, aadA2, aadA5, and aph(4)-Ia), two phenicol resistance genes (catB3 and floR), and five trimethoprim/sulfamethoxazole resistance genes (sul1/2/3 and dfrA12/17) were also identified. A total of 191 virulence genes were identified. Among them, 57 belonged to type-three secretion system (T3SS) encoding genes, 55 belonged to fimbrial adherence encoding genes, and 39 belonged to flagella-encoding genes CONCLUSIONS: This study demonstrated that multi-resistance mechanisms consistent with an XDR-phenotype, along with various virulence encoding genes of a S. Indiana strain in China These findings highlight the importance of cooperation among different sectors in order to monitor the spread of resistant pathogens among food animal, foods of animal origin and human beings that might further take measures to protect consumers' health.

Dealing with aggressive behavior within the health care team: a leadership challenge.
Hynes, Patricia; Kissoon, Niranjan; Hamielec, Cindy M; Greene, Anne Marie; Simone, Carmine
2006-06-01
During an interdisciplinary Canadian leadership forum [ (click on the Conferences icon)], participants were challenged to develop an approach to a difficult leadership/management situation. In a scenario involving aggressive behavior among health care providers, participants identified that, before responding, an appropriate leader should collect additional information to identify the core problem(s) causing such behavior. Possibilities include stress; lack of clear roles, responsibilities, and standard operating procedures; and, finally, lack of training on important leadership/management skills. As a result of these core problems, several potential solutions are possible, all with potential obstacles to implementation. Additional education around communication and team interaction was felt to be a priority. In summary, clinical leaders probably have a great deal to gain from augmenting their leadership/management skills.

The role of leadership in the management and delivery of health and allied health services is often discussed but lacks empirical research. Discrepancies are often found between leaders' self-ratings and followers' ratings of the leader. To our knowledge no research has examined leader-follower discrepancies and their association with organizational culture in mental health clinics. The current study examines congruence, discrepancy, and directionality of discrepancy in relation to organizational culture in 38 mental health teams (N = 276). Supervisors and providers completed surveys including ratings of the supervisor transformational leadership and organizational culture. Polynomial regression and response surface analysis models were computed examining the associations of leadership discrepancy and defensive organizational culture and its subscales. Discrepancies between supervisor and provider reports of transformational leadership were associated with a more negative organizational culture. Culture suffered more where supervisors rated themselves more positively than providers, in contrast to supervisors rating themselves lower than the provider ratings of the supervisor. Leadership and leader discrepancy should be a consideration in improving organizational culture and for strategic initiatives such as quality of care and the implementation and sustainment of evidence-based practice.

Trauma teams responsible for the first response to patients with multiple injuries upon arrival in a hospital consist of medical specialists or resident physicians. We hypothesized that 24-hour video registration in the trauma room would allow for precise evaluation of team functioning and deviations from Advanced Trauma Life Support (ATLS) protocols. We analyzed all video registrations of trauma patients who visited the emergency room of a Level I trauma center in the Netherlands between September 1, 2000, and September 1, 2002. Analysis was performed with a score list based on ATLS protocols. From a total of 1,256 trauma room presentations, we found a total of 387 video registrations suitable for analysis. The majority of patients had an injury severity score lower than 17 (264 patients), whereas 123 patients were classified as multiple injuries (injury severity score >or=17). Errors in team organization (omission of prehospital report, no evident leadership, unorganized resuscitation, not working according to protocol, and no continued supervision of the patient) lead to significantly more deviations in the treatment than when team organization was uncomplicated. Video registration of diagnostic and therapeutic procedures by a multidisciplinary trauma team facilitates an accurate analysis of possible deviations from protocol. In addition to identifying technical errors, the role of the team leader can clearly be analyzed and related to team actions. Registration strongly depends on availability of video tapes, timely started registration, and hardware functioning. The results from this study were used to develop a training program for trauma teams in our hospital that specifically focuses on the team leader's functioning.

Leadership and team building in gastrointestinal endoscopy.
Valori, Roland M; Johnston, Deborah J
2016-06-01
A modern endoscopy service delivers high volume procedures that can be daunting, embarrassing and uncomfortable for patients [1]. Endoscopy is hugely beneficial to patients but only if it is performed to high standards [2]. Some consequences of poor quality endoscopy include worse outcomes for cancer and gastrointestinal bleeding, unnecessary repeat procedures, needless damage to patients and even avoidable death [3]. New endoscopy technology and more rigorous decontamination procedures have made endoscopy more effective and safer, but they have placed additional demands on the service. Ever-scarcer resources require more efficient, higher turnover of patients, which can be at odds with a good patient experience, and with quality and safety. It is clear from the demands put upon it, that to deliver a modern endoscopy service requires effective leadership and team working [4]. This chapter explores what constitutes effective leadership and what makes great clinical teams. It makes the point that endoscopy services are not usually isolated, independent units, and as such are dependent for success on the organisations they sit within. It will explain how endoscopy services are affected by the wider policy and governance context. Finally, within the context of the collection of papers in this edition of Best Practice & Research: Clinical Gastroenterology, it explores the potentially conflicting relationship between training of endoscopists and service delivery. The effectiveness of leadership and teams is rarely the subject of classic experimental designs such as randomized controlled trials. Nevertheless there is a substantial literature on this subject within and particularly outside healthcare [5]. The authors draw on this wider, more diffuse literature and on their experience of delivering a Team Leadership Programme (TLP) to the leaders of 70 endoscopy teams during the period 2008-2012.

Reablement is an early and time-limited home-based rehabilitation intervention that emphasizes intensive, goal-oriented, and multidisciplinary assistance for people experiencing functional decline. Few empirical studies to date have examined the experiences of the integrated multidisciplinary teams involved in reablement. Accordingly, the aim of this study was to explore and describe how an integrated multidisciplinary team in Norway experienced participation in reablement. An integrated multidisciplinary team consisting of health care professionals with a bachelor's degree (including a physiotherapist, a social educator, occupational therapists, and nurses) and home-based care personnel without a bachelor's degree (auxiliary nurses and nursing assistants) participated in focus group discussions. Qualitative content analysis was used to analyze the resulting data. Three main themes emerged from the participants' experiences with participating in reablement, including "the older adult's goals are crucial", "a different way of thinking and acting - a shift in work culture", and "a better framework for cooperation and application of professional expertise and judgment". The integrated multidisciplinary team and the older adults collaborated and worked in the same direction to achieve the person's valued goals. The team supported the older adults in performing activities themselves rather than completing tasks for them. To facilitate cooperation and application of professional expertise and judgment, common meeting times and meeting places for communication and supervision were necessary. Structural factors that promote integrated multidisciplinary professional decisions include providing common meeting times and meeting places as well as sufficient time to apply professional knowledge when supervising and supporting older persons in everyday activities. These findings have implications for practice and suggest future directions for improving health care services. The

Do lightning positive leaders really "step"?
NASA Astrophysics Data System (ADS)
Petersen, D.
2015-12-01
It has been known for some time that positive leaders exhibit impulsive charge motion and optical emissions as they extend. However, laboratory and field observations have not produced any evidence of a process analogous to the space leader mechanism of negative leader extension. Instead, observations have suggested that the positive leader tip undergoes a continuous to intermittent series of corona streamer bursts, each burst resulting in a small forward extension of the positive leader channel. Traditionally, it has been held that lightning positive leaders extend in a continuous or quasi-continuous fashion. Lately, however, many have become concerned that this position is incongruous with observations of impulsive activity during lightning positive leader extension. It is increasingly suggested that this impulsive activity is evidence that positive leaders also undergo "stepping". There are two issues that must be addressed. The first issue concerns whether or not the physical processes underlying impulsive extension in negative and positive leaders are distinct. We argue that these processes are in fact physically distinct, and offer new high-speed video evidence to support this position. The second issue regards the proper use of the term "step" as an identifier for the impulsive forward extension of a leader. Traditional use of this term has been applied only to negative leaders, due primarily to their stronger impulsive charge motions and photographic evidence of clearly discontinuous forward progression of the luminous channel. Recently, due to the increasing understanding of the distinct "space leader" process of negative leader extension, the term "step" has increasingly come to be associated with the space leader process itself. Should this emerging association, "step" = space leader attachment, be canonized? If not, then it seems reasonable to use the term "step" to describe impulsive positive leader extension. If, however, we do wish to associate the

The purpose of the study is to evaluate the impact of primary service involvement on rapid response team (RRT) evaluations. The study is a combination of retrospective chart review and prospective survey-based evaluation. Data included when and where the activations occurred and the patient's code status, primary service, and ultimate disposition. These data were correlated with survey data from each event. A prospective survey evaluated the primary team's involvement in decision making and the overall subjective quality of the interaction with primary service through a visual analog scale. We analyzed 4408 RRTs retrospectively and an additional 135 prospectively. The primary team's involvement by telephone or in person was associated with significantly more transfers to higher care levels in retrospective (P < .01) and prospective data sets. Code status was addressed more frequently in primary team involvement, with more frequent changes seen in the retrospective analysis (P = .01). Subjective ratings of communication by the RRT leader were significantly higher when the primary service was involved (P < .001). Active primary team involvement influences RRT activation processes of care. The RRT role should be an adjunct to, but not a substitute for, an engaged and present primary care team.

This paper discusses a leadership program implemented in the School of Nursing at Edith Cowan University to develop leadership in fourth semester nursing students enrolled in a three year undergraduate nursing degree to prepare them for the dynamic 'changing world' environment of healthcare. Students were invited to apply to undertake the program in extracurricular time. Nineteen students applied to the program and ten were chosen to participate in the program. The numbers were limited to ten to equal selected industry leader mentors. The leadership program is based on the belief that leadership is a function of knowing oneself, having a vision that is well communicated, building trust among colleagues, and taking effective action to realize one's own potential. It is asserted that within the complexity of health care it is vital that nurses enter the clinical setting with leadership capabilities because graduate nurses must take the lead to act autonomously, make decisions at the point of service, and develop a professional vision that fits with organizational and professional goals Thus, the more practice students have with leadership skills, the more prepared they will be to enter the workforce. The program consists of three components: leadership knowledge, leadership skills and leadership-in-action. The leadership program focuses on the student-participant's ability to be self reflective on personal leadership qualities, critically appraise, and work within a team as well as to take responsibility for ensuring the achievement of team goals as leader. The program is practical and is reliant on the involvement of leader mentors who hold positions of leadership with the health industry in Western Australia. Students completed a pre and post program questionnaire related to abilities and skills in leadership. This paper discusses pre and post evaluation data against program outcomes. The findings demonstrate that participants of the program increased their ability

Background The accountable care organization (ACO) is a new type of health care organization incentivized to improve quality of care, improve population health, and reduce the total cost of care. An ACO’s success in meeting these objectives will depend greatly upon its ability to improve patient care management. Numerous studies have found relational coordination to be positively associated with key measures of organizational performance in health care organizations, including quality and efficiency. Purpose The purpose of this paper is twofold: (1) identify the extent to which ACO leaders are aware of the dimensions of relational coordination, and (2) identify the ways these leaders believe the dimensions influenced care management practices in their organization. Methodology/Approach We performed content analysis of interviews with managerial and clinical leaders from a diverse group of 11 ACOs to assess awareness of relational coordination and identify the ways that dimensions of relational coordination were perceived to influence development of care management practices. Findings ACO leaders mentioned four relational coordination dimensions: shared goals, frequency of communication, timeliness of communication, and problem solving communication. Three dimensions – shared knowledge of team members’ tasks, mutual respect, and accuracy of communication – were not mentioned. Our analysis identified numerous ways leaders believed the four mentioned dimensions contributed to the development of care management, including contributions to standardization of care, patient engagement, coordination of care, and care planning. Discussion We propose two hypotheses for future research on relational coordination and care management. Practice Implications If relational coordination is to have a beneficial influence on ACO performance, organizational leaders must become more aware of relational coordination and its various dimensions and become cognizant of relational

Leaders who create change and those who manage it. How leaders limit success.
Bruhn, John G
2004-01-01
There is no formula for either leading or managing change. Every organization and leader is unique. Leading change, however, is more art than science. Managing change is more science than art. Leading change is not simply a matter of a leader's style or personality; it is a leader's philosophy of how to generate and mobilize the total resources of an organization to enable it to be its best. Managing change, on the other hand, is focused on maintaining stability in an organization and containing the effects of unwanted and unexpected change. Leaders set the limits of success in their organizations by how they manage change. The different approaches of 2 leaders who have created change to correct problems in our health care delivery system are discussed.

Cardiovascular leaders moving beyond logic: an active strategy for advancing cardiac services.
Greisler, D S; Stupak, R J
1997-01-01
Cardiac leaders need to put forth cogent, well-articulated, conceptually sound reasons for pursuing issues that they consider to be significant to the future of their service. Logic, rationality, and quantification of issues are "givens"--they are the price of admission that one pays to have an issue contested in the organizational arena. Understanding the larger sphere in which CV issues reside by contextualizing logic and rationality in terms of organizational culture, power, politics, group dynamics, and ego improves the chance that the cardiac agenda will receive thoughtful consideration and support by organizational decision-makers. Clearly, optimal CV performance can only be attained through the process of sophisticated interdependence. Accordingly, by understanding and using the Iceberg in its entirety, CV leaders will manifest the power of it to bring about constructive change and market viability. The completed model appears in Figure 6. As your cardiovascular team advocates for the CV agenda, take care to "be as wary as snakes but as harmless as doves.

Delivering team training to medical home staff to impact perceptions of collaboration.
Treadwell, Janet; Binder, Brenda; Symes, Lene; Krepper, Rebecca
2015-01-01
The purpose of this study was to explore whether an evidence-based educational and experiential intervention to develop team skills in medical homes would positively affect team members' perceptions of interprofessional collaboration. The study population consisted of primary care medical home practices associated with the health plan sponsor of this research. All practices were located within the greater Houston region of Texas and had more than 500 patients. A cluster design experimental study was conducted between August 2013 and June 2014. Fifty medical home practices, 25 intervention and 25 attention control, were recruited as study sites. Results indicate that individual team members in the medical homes receiving the intervention were significantly more likely than the individual team members in the attention control groups to report higher levels of positive perception of team collaboration after the 12-week intervention. This research indicates that educating teams about interprofessional collaboration tools and supporting technique use may be an effective strategy to assist medical homes in developing collaborative environments. Case management experience in collaboration supports the role facilitating team training. Transforming culture from hierarchical to team-based care supports the case management approach of collaborative practice. In addition, role satisfaction attained through the respect and communication of team-based care delivery may influence retention within the case management profession. As case managers in primary care settings assume roles of embedded care coordinators, program leaders, and transition facilitators, an understanding of collaboration techniques is needed to support the entire care team to achieve desired outcomes.

Project Development Teams: A Novel Mechanism for Accelerating Translational Research
Sajdyk, Tammy J.; Sors, Thomas G.; Hunt, Joe D.; Murray, Mary E.; Deford, Melanie E.; Shekhar, Anantha; Denne, Scott C.
2014-01-01
The trend in conducting successful biomedical research is shifting from individual academic labs to coordinated collaborative research teams. Teams of experienced investigators with a wide variety of expertise are now critical for developing and maintaining a successful, productive research program. However, assembling a team whose members have the right expertise requires a great deal of time and many resources. To assist investigators seeking such resources, the Indiana Clinical and Translational Sciences Institute (Indiana CTSI) created the Project Development Teams (PDTs) Program to support translational research on and across the Indiana University-Purdue University Indianapolis, Indiana University, Purdue University, and University of Notre Dame campuses. PDTs are multidisciplinary committees of seasoned researchers who assist investigators, at any stage of research, in transforming ideas/hypotheses into well-designed translational research projects. The teams help investigators capitalize on Indiana CTSI resources by providing investigators with, as needed, mentoring and career development; protocol development; pilot funding; institutional review board, regulatory, and/or nursing support; intellectual property support; access to institutional technology; and assistance with biostatistics, bioethics, recruiting participants, data mining, engaging community health, and collaborating with other investigators. Indiana CTSI leaders have analyzed metrics, collected since the inception of the PDT Program in 2008 from both investigators and team members, and found evidence strongly suggesting that the highly responsive teams have become an important one-stop venue for facilitating productive interactions between basic and clinical scientists across four campuses, have aided in advancing the careers of junior faculty, and have helped investigators successfully obtain external funds.

Code Blue Emergencies: A Team Task Analysis and Educational Initiative.
Price, James W; Applegarth, Oliver; Vu, Mark; Price, John R
2012-01-01
The objective of this study was to identify factors that have a positive or negative influence on resuscitation team performance during emergencies in the operating room (OR) and post-operative recovery unit (PAR) at a major Canadian teaching hospital. This information was then used to implement a team training program for code blue emergencies. In 2009/10, all OR and PAR nurses and 19 anesthesiologists at Vancouver General Hospital (VGH) were invited to complete an anonymous, 10 minute written questionnaire regarding their code blue experience. Survey questions were devised by 10 recovery room and operation room nurses as well as 5 anesthesiologists representing 4 different hospitals in British Columbia. Three iterations of the survey were reviewed by a pilot group of nurses and anesthesiologists and their feedback was integrated into the final version of the survey. Both nursing staff (n = 49) and anesthesiologists (n = 19) supported code blue training and believed that team training would improve patient outcome. Nurses noted that it was often difficult to identify the leader of the resuscitation team. Both nursing staff and anesthesiologists strongly agreed that too many people attending the code blue with no assigned role hindered team performance. Identifiable leadership and clear communication of roles were identified as keys to resuscitation team functioning. Decreasing the number of people attending code blue emergencies with no specific role, increased access to mock code blue training, and debriefing after crises were all identified as areas requiring improvement. Initial team training exercises have been well received by staff.

The trend in conducting successful biomedical research is shifting from individual academic labs to coordinated collaborative research teams. Teams of experienced investigators with a wide variety of expertise are now critical for developing and maintaining a successful, productive research program. However, assembling a team whose members have the right expertise requires a great deal of time and many resources. To assist investigators seeking such resources, the Indiana Clinical and Translational Sciences Institute (Indiana CTSI) created the Project Development Teams (PDTs) program to support translational research on and across the Indiana University-Purdue University Indianapolis, Indiana University, Purdue University, and University of Notre Dame campuses. PDTs are multidisciplinary committees of seasoned researchers who assist investigators, at any stage of research, in transforming ideas/hypotheses into well-designed translational research projects.

2018-12-01
The current study examines the feasibility and potential effects of long distance, remote simulation training on team dynamics. The study design was a prospective study evaluating team dynamics before and after remote simulation. Study subjects consisted of interdisciplinary teams (attending physicians, physicians in training, advanced care practitioners, and/or nurses). The study was conducted at nine training sites in eight countries. Study subjects completed 2-3 simulation scenarios of acute crises before and after training with the Checklist for Early Recognition and Treatment of Acute Illness (CERTAIN). Pre- and post-CERTAIN training simulations were evaluated by two independent reviewers utilizing the Team Emergency Assessment Measure (TEAM), which is a 11-item questionnaire that has been validated for assessing teamwork in the intensive care unit. Any discrepancies of greater than 1 point between the two reviewers on any question on the TEAM assessment were sent to a third reviewer to judge. The score that was deemed discordant by the third judge was eliminated. Pre- and post-CERTAIN training TEAM scores were averaged and compared. Of the nine teams evaluated, six teams demonstrated an overall improvement in global team performance following CERTAIN virtual training. For each of the 11 TEAM assessments, a trend toward improvement following CERTAIN training was noted; however, no assessment had universal improvement. 'Team composure and control' had the least absolute score improvement following CERTAIN training. The greatest improvement in the TEAM assessment scores was in the 'team's ability to complete tasks in a timely manner' and in the 'team leader's communication to the team'. The assessment of team dynamics using long distance, virtual simulation training appears to be feasible and may result in improved team performance during simulated patient crises; however, language and video quality were the two largest barriers noted during the review process.

Leadership coaching is becoming an increasingly important intervention that helps individual nurse executives and managers develop and use the best of their strengths, gifts, and talents. As the need for leadership in nursing becomes urgent and brave souls move into the positions of greater authority and potential impact, they will face challenges as they move up in rank. This article identifies the hidden and often-overlooked challenges that are faced by new leaders as they transition into roles of increased responsibility, and it demonstrates how leadership coaching can help new leaders make successful transitions. As the current health care crisis creates opportunity for new leaders, those who opt for promotions and lateral shifts encounter both expected and surprising challenges. The expected challenges include mastering new content skills, learning new organizational structures, and getting to know new teams. The less obvious stressors include issues of self-esteem, assertiveness, self-consciousness, self-criticism, perfectionism, new boundaries, changing identities, and finding one's own leadership style. These important issues are often kept out of conscious awareness and overlooked at great cost to the individual leader and her institution. Leadership coaching can provide support and practical strategies for managing and overcoming these hidden challenges.

Leader-Member Exchange (LMX) theory suggests that the quality of the leader-employee relationship is linked to employee psychological health. Leaders who reside at different hierarchical levels have unique roles and spheres of influence and potentially affect employees' work experiences in different ways. Nevertheless, research on the impact of leadership on employee psychological health has largely viewed leaders as a homogeneous group. Expanding on LMX theory, we argue that (1) LMX sourced at the levels of the line manager (LM) and senior management (SM) team will be differentially linked to employee psychological health (assessed as worn-out) and that (2) these relationships will be mediated by perceived work characteristics (reward and recognition, workload management, quality of relationships with colleagues and physical environment). Structural equation modelling on data from 337 manual workers partially supported the hypotheses. Perceptions of the physical environment mediated the relationship between LMX at the LM level and employee psychological health, whereas perceptions of workload management mediated the relationship between LMX at the SM level and psychological health. These findings corroborate arguments that leaders are not a uniform group and as such the effects of LMX on employees will depend on leadership hierarchy. Implications for expanding leadership theory are discussed.

The role of simulation-based education continues to expand exponentially. To excel in this environment as a surgical simulation leader requires unique knowledge, skills, and abilities that are different from those used in traditional clinically-based education. Leaders in surgical simulation were invited to participate as discussants in a pre-conference course offered by the Association for Surgical Education. Highlights from their discussions were recorded. Recommendations were provided on topics such as building a simulation team, preparing for accreditation requirements, what to ask for during early stages of development, identifying tools and resources needed to meet educational goals, expanding surgical simulation programming, and building educational curricula. These recommendations provide new leaders in simulation with a unique combination of up-to-date best practices in simulation-based education, as well as valuable advice gained from lessons learned from the personal experiences of national leaders in the field of surgical simulation and education.

Career anchors of dentist leaders.
Tuononen, Tiina; Lammintakanen, Johanna; Suominen, Anna Liisa
2016-08-01
The work of a health care leader is demanding; in order to cope, leaders need motivation and support. The occurrence of intrinsic factors called career anchors (combination of one's competence, motives and values) could be a contributing factor in dentist leaders' career decisions. The aim of our study was to identify dentist leaders' career anchors and their association to dentist leaders' retention or turnover of the leadership position. Materials were gathered in 2014 via an electronic questionnaire from 156 current (Leaders) or former (Leavers) Finnish dentist leaders. Career anchor evaluation was conducted by the questionnaire and scoring-table taken from Edgar Schein's Career Anchors Self-Assessment. Both the most and the least important career anchors were detected by the highest and lowest scores and their occurrence reported as percentages. Associations between career anchor scores and tendency to stay were analyzed with logistic regression. 'Technical/Functional Competence' and 'Lifestyle' were most frequently reported as the most important and 'Entrepreneurial Creativity' and 'General Managerial Competence' as the least important career anchors. However, a higher level of 'General Managerial Competence' anchor was most significantly associated with staying in a leadership position. Instead, 'Pure Challenge' and 'Lifestyle' decreased the odds to stay. The knowledge of the important and essential career anchors of dentist leaders' and individuals' could perform crucial part in career choices and also in planning education, work opportunities and human resource policies promoting retention of dentist leaders and probably also other health care leaders.

There is a pressing workforce shortage and leadership scarcity in palliative care to adequately meet the demands of individuals with serious illness and their families. To address this gap, the Cambia Health Foundation launched its Sojourns Scholars Leadership Program in 2014, an initiative designed to identify, cultivate, and advance the next generation of palliative care leaders. This report intends to summarize the second cohort of Sojourns Scholars' projects and their reflection on their leadership needs. This report summarizes the second cohort of sojourns scholars' project and their reflection on leadership needs. After providing a written reflection on their own projects, the second cohort participated in a group interview (fireside chat) to elicit their perspectives on barriers and facilitators in providing palliative care, issues facing leadership in palliative care in the United States, and lessons from personal and professional growth as leaders in palliative care. They analyzed the transcript of the group interview using qualitative content analysis methodology. Three themes emerged from descriptions of the scholars' project experience: challenges in palliative care practice, leadership strategies in palliative care, and three lessons learned to be a leader were identified. Challenges included perceptions of palliative care, payment and policy, and workforce development. Educating and collaborating with other clinicians and influencing policy change are important strategies used to advance palliative care. Time management, leading team effort, and inspiring others are important skills that promote effectiveness as a leader. Emerging leaders have a unique view of conceptualizing contemporary palliative care and shaping the future. Providing comprehensive, coordinated care that is high quality, patient and family centered, and readily available depends on strong leadership in palliative care. The Cambia Scholars Program represents a unique opportunity.

This paper develops optimal control protocols for the distributed output synchronization problem of leader-follower multiagent systems with an active leader. Agents are assumed to be heterogeneous with different dynamics and dimensions. The desired trajectory is assumed to be preplanned and is generated by the leader. Other follower agents autonomously synchronize to the leader by interacting with each other using a communication network. The leader is assumed to be active in the sense that it has a nonzero control input so that it can act independently and update its control to keep the followers away from possible danger. A distributed observer is first designed to estimate the leader's state and generate the reference signal for each follower. Then, the output synchronization of leader-follower systems with an active leader is formulated as a distributed optimal tracking problem, and inhomogeneous algebraic Riccati equations (AREs) are derived to solve it. The resulting distributed optimal control protocols not only minimize the steady-state error but also optimize the transient response of the agents. An off-policy reinforcement learning algorithm is developed to solve the inhomogeneous AREs online in real time and without requiring any knowledge of the agents' dynamics. Finally, two simulation examples are conducted to illustrate the effectiveness of the proposed algorithm.

Walk the Talk: Teachers as Leaders in Climate Change Education
NASA Astrophysics Data System (ADS)
Warburton, J.; Bartholow, S.; Larson, A.
2014-12-01
The notion of teachers as leaders and communicators is not new but rather it has been limited in scope. Teachers have long served as team leaders, department chairs, and curriculum developers. But what happens when you go beyond these typical roles in professional development? Can teachers become lead communicators beyond the classroom? Can they become leaders of change on important topics like the climate? For nearly a decade, PolarTREC (Teachers and Researchers Exploring and Collaborating), funded by the National Science Foundation, has been teaming teachers with research projects in all fields of polar science. Teachers participate in hands-on field research experiences in the polar regions which focus heavily on climate change and climate science. Administrated by the Arctic Research Consortium of the United States, the goal of PolarTREC is to invigorate polar science education and understanding by bringing K-12 educators and polar researchers together. The program fosters a teacher and researcher network, which accelerates the cross-pollination of knowledge in science practices, findings, and classroom implementation throughout disciplines. Evaluation data exposes a crucial dynamic that increases the potential for a successful climate change science campaign. Data indicates that teachers can tackle challenges such as reframing climate change science to better address the need for a particular campaign, as well as garnering the science project the necessary support through effective, authentic, and tangible communication efforts to policymakers, funders, students, and the public. Researchers reported the value of explaining their science, in-situ, allowed them to reframe and rework the objectives of the science project to attain meaningful outcomes. More than half of the researchers specifically noted that one of the strengths of the PolarTREC project is its benefit to the scientific process. The researchers also viewed PolarTREC as an essential outreach

Challenges of interprofessional team training: a qualitative analysis of residents' perceptions.
van Schaik, Sandrijn; Plant, Jennifer; O'Brien, Bridget
2015-01-01
Simulation-based interprofessional team training is thought to improve patient care. Participating teams often consist of both experienced providers and trainees, which likely impacts team dynamics, particularly when a resident leads the team. Although similar team composition is found in real-life, debriefing after simulations puts a spotlight on team interactions and in particular on residents in the role of team leader. The goal of the current study was to explore residents' perceptions of simulation-based interprofessional team training. This was a secondary analysis of a study of residents in the pediatric residency training program at the University of California, San Francisco (United States) leading interprofessional teams in simulated resuscitations, followed by facilitated debriefing. Residents participated in individual, semi-structured, audio-recorded interviews within one month of the simulation. The original study aimed to examine residents' self-assessment of leadership skills, and during analysis we encountered numerous comments regarding the interprofessional nature of the simulation training. We therefore performed a secondary analysis of the interview transcripts. We followed an iterative process to create a coding scheme, and used interprofessional learning and practice as sensitizing concepts to extract relevant themes. 16 residents participated in the study. Residents felt that simulated resuscitations were helpful but anxiety provoking, largely due to interprofessional dynamics. They embraced the interprofessional training opportunity and appreciated hearing other healthcare providers' perspectives, but questioned the value of interprofessional debriefing. They identified the need to maintain positive relationships with colleagues in light of the teams' complex hierarchy as a barrier to candid feedback. Pediatric residents in our study appreciated the opportunity to participate in interprofessional team training but were conflicted about the

Who helps the leaders? Difficulties experienced by cancer support group leaders.
Kirsten, Laura; Butow, Phyllis; Price, Melanie; Hobbs, Kim; Sunquist, Kendra
2006-07-01
Cancer support groups are an important source of support for cancer patients, yet little is known about the challenges and training needs of both professionally trained and untrained leaders. The aim of this study was to discover the difficulties experienced and training desired by cancer support group leaders. Twenty-seven leaders of 34 cancer support groups participated in focus groups or individual interviews. Groups were purposively selected as representative of 173 support groups identified in New South Wales which were for adults with cancer and/or their adult carers and were not therapeutic or education-only groups. Difficulties identified included dealing with people's different communication styles and needs; dealing with recurrence, metastases and death; practical issues, including resources, setting the programme and funding security; maintaining personal balance and preventing burn out; establishing group credibility; dealing with group cycles; and leading groups in rural areas. Leaders also identified benefits and rewards from group leadership such as contributing to others' well-being, self-development and insight into others' lives. Non-professionally trained leaders experienced more difficulties, particularly in dealing with group process and practical issues. Difficulties identified were related both to working with a cancer population specifically and to working with groups in general. While some issues were common to both health professionals and non-health professionals, non-health professionals reported greater supportive needs. Clear guidelines, targeted training and development of better methods of support to reduce the stress and burn out experienced by group leaders are needed.

Remembering the Leaders of China.
Fu, Mingchen; Xue, Yan; DeSoto, K Andrew; Yuan, Ti-Fei
2016-01-01
In two studies, we examined Chinese students' memory for the names of the leaders of China. In Study 1, subjects were cued with the names of periods from China's history. Subjects listed as many leaders as possible from each period and put them in the correct ordinal position when they could (see Roediger and DeSoto, 2014). Results showed that within each period, a primacy effect and sometimes a recency effect emerged. Moreover, the average recall probability for leaders within a specific period was a function of the ordinal position of the period. In Study 2, we asked another group of subjects to identify the sources through which they were able to recall each leader. We found that most subjects remembered leaders due to class and coursework. We also found a relation between a leader's recall probability and the amount of information available on that leader on the Internet. Our findings further imply that the serial position function captures the form of collective memory.

Trust and team performance: A meta-analysis of main effects, moderators, and covariates.
De Jong, Bart A; Dirks, Kurt T; Gillespie, Nicole
2016-08-01
Cumulating evidence from 112 independent studies (N = 7,763 teams), we meta-analytically examine the fundamental questions of whether intrateam trust is positively related to team performance, and the conditions under which it is particularly important. We address these questions by analyzing the overall trust-performance relationship, assessing the robustness of this relationship by controlling for other relevant predictors and covariates, and examining how the strength of this relationship varies as a function of several moderating factors. Our findings confirm that intrateam trust is positively related to team performance, and has an above-average impact (ρ = .30). The covariate analyses show that this relationship holds after controlling for team trust in leader and past team performance, and across dimensions of trust (i.e., cognitive and affective). The moderator analyses indicate that the trust-performance relationship is contingent upon the level of task interdependence, authority differentiation, and skill differentiation in teams. Finally, we conducted preliminary analyses on several emerging issues in the literature regarding the conceptualization and measurement of trust and team performance (i.e., referent of intrateam trust, dimension of performance, performance objectivity). Together, our findings contribute to the literature by helping to (a) integrate the field of intrateam trust research, (b) resolve mixed findings regarding the trust-performance relationship, (c) overcome scholarly skepticism regarding the main effect of trust on team performance, and (d) identify the conditions under which trust is most important for team performance.

On the Transition from Initial Leader to Stepped Leader in Negative Cloud-to-ground Lightning
NASA Astrophysics Data System (ADS)
Stolzenburg, M.; Marshall, T. C.; Karunarathne, S.; Orville, R. E.
2017-12-01
High-speed video and electric field change (E-change) data are used to describe the first 5 ms of a natural negative cloud-to-ground (CG) flash. These observations reveal differences in appearance of both the video luminosity and the E-change pulses before the leader transitions to propagating as a negative stepped leader (SL). During the initial breakdown (IB) stage, the initial leader advances intermittently forward in jumps of 78-175 m, at intervals of 100-280 μs, and in separate bursts that are bright for a few 20-μs video frames. The IB pulses accompanying these luminosity bursts have long duration, large amplitude, and a characteristic bipolar shape in nearby E-change observations. In the time between IB pulses, the initial leader is very dim or not visible during the earliest 1-2 ms of the IB stage. Over the next few milliseconds, the leader propagation transitions to an early SL phase, in which the leader tips advance 20-59 m forward at more regular intervals of 40-80 μs during relatively dim and brief steps. In the E-change data, the accompanying SL pulses have very short duration, small amplitude, and are typically unipolar. These data indicate that when the entire initial leader length behind the lower end begins to remain illuminated between bursts, the propagation mode changes from IB bursts to SL steps, and the IB stage ends. Additional differences in initial leader character are evident during the return stroke, as its luminosity speed decreases sharply upon reaching the topmost initial leader section of the channel, and that section of channel does not saturate the video intensity. Results of these analyses support a prior hypothesis that the early initial leader development occurs in the absence of a continuously hot channel, and consequently, the initial leader propagation is unlike the self-propagating advance of the later stepped leader.

How to create high-performing teams.
Lam, Samuel M
2010-02-01
This article is intended to discuss inspirational aspects on how to lead a high-performance team. Cogent topics discussed include how to hire staff through methods of "topgrading" with reference to Geoff Smart and "getting the right people on the bus" referencing Jim Collins' work. In addition, once the staff is hired, this article covers how to separate the "eagles from the ducks" and how to inspire one's staff by creating the right culture with suggestions for further reading by Don Miguel Ruiz (The four agreements) and John Maxwell (21 Irrefutable laws of leadership). In addition, Simon Sinek's concept of "Start with Why" is elaborated to help a leader know what the core element should be with any superior culture. Thieme Medical Publishers.

Background Fewer than half of all U.S. adults meet the 2008 Physical Activity Guidelines. Leader behaviors and group cohesion have been associated with increased participation or adherence in sports team and exercise class settings. Physical activity interventions in community settings that encompass these factors may enhance intervention adherence. Purpose To examine the impact of Community Health Promoter leader behaviors and group cohesion on participation in a walking group intervention among racially/ethnically diverse adults in low-to-moderate income communities in Detroit, Mich. Design Data for the current study were drawn from the Walk Your Heart to Health (WYHH) data set. WYHH was a multi-site cluster randomized controlled study with a lagged intervention and outcome measurements at baseline, four, eight, and 32 weeks. Pooled survey data from both intervention arms is used for the current study. Data were analyzed between August 2013 and October 2014. Setting/participants A total of 603 non-Hispanic Black, non-Hispanic White, and Hispanic adults across five cohorts that began the 32-week WYHH intervention between March 2009 and October 2011. Intervention A 32-week long walking group program hosted by community- and faith-based organizations and facilitated by Community Health Promoters. Walking groups met three times per week for 90-minutes per session. To promote participation in or adherence to WYHH, Community Health Promoters used evidence-based strategies to facilitate group cohesion. Group members assumed increasing leadership responsibility for facilitating sessions over time. Main outcome measures Participation in WYHH as measured by consistency of attendance. Results Community Health Promoter leader behaviors were positively associated with participation in WYHH. Social but not task cohesion was significantly associated with consistent participation. Social cohesion may mediate the relationship between leader behaviors and walking group

Are Empowered Employees More Proactive? The Contingency of How They Evaluate Their Leader
Yin, Kui; Xing, Lu; Li, Can; Guo, Yungui
2017-01-01
Finding ways to enhance employee proactive behavior is a focal concern for academics and practitioners. Previous studies have found a positive association between empowering leadership and proactive behavior (Martin et al., 2013; Li et al., 2017). However, these studies lack elaboration on mechanisms and do not rule out the effect of employees’ proactive personality during empirical testing. We investigate empowering leadership from individual perspective due to the variation of empowerment levels even in the same team. Our research proposes a more elaborated theoretical model that explains why, and when, empowering leadership might promote employee proactive behavior. Specifically, we examine mediating mechanisms based on social cognitive theory and propose trust in leader competency as boundary condition. Using a sample of 280 leader–follower dyads from a large state-owned Chinese company, our results revealed that (1) empowering leadership was positively related to proactive behavior, with role breadth self-efficacy acting as a mediator for this relationship; (2) employees’ trust in leader competency moderated both the empowering leadership–subordinate proactive behavior relationship and the mediating effect of role breadth self-efficacy, such that the empowering leadership–subordinate proactive behavior relationship was weaker, and the mediating effect of role breadth self-efficacy was stronger, for employees with high levels of trust in leader competency.

The aim of this study was to investigate the spread and location of the fosA3 gene among Enterobacteriaceae from diseased broiler chickens. Twenty-nine Escherichia coli and seven Proteus mirabilis isolates recovered from one chicken farm were screened for the presence of plasmid-mediated fosfomycin resistance genes by PCR. The clonal relatedness of fosA3-positive isolates, the transferability and location of fosA3, and the genetic context of the fosA3 gene were determined. Seven P. mirabilis isolates with three different pulsed-field gel electrophoresis (PFGE) patterns and five E. coli isolates belonging to sequence type 117 (ST117) and phylogenetic group D were positive for fosA3 and all carried the bla CTX-M gene. In E. coli, the genetic structures IS26-ISEcp1-bla CTX-M-65 -IS26-fosA3-1758 bp-IS26 and IS26-ISEcp1-bla CTX-M-3 -bla TEM-1 -IS26-fosA3-1758 bp-IS26 were present on transferable IncHI2/ST3 and F2:A-:B- plasmids, respectively. However, fosA3 was located on the chromosome of the seven P. mirabilis isolates. IS26-ISEcp1-bla CTX-M-65 -IS26-fosA3-1758 bp-IS26 and IS26-bla CTX-M-14 -611 bp-fosA3-1222 bp-IS26 were detected in three and four P. mirabilis isolates, respectively. Minicircles that contained both fosA3 and bla CTX-M-65 were shared between E. coli and P. mirabilis. This is the first report of the fosA3 gene integrated into the chromosome of P. mirabilis isolates with the bla CTX-M gene. The emergence and clonal spread of avian pathogenic E. coli ST117 with the feature of multidrug resistance and high virulence are a serious problem.
