Hidden profiles and concealed information: strategic information sharing and use in group decision making.

PubMed

Toma, Claudia; Butera, Fabrizio

2009-06-01

Two experiments investigated the differential impact of cooperation and competition on strategic information sharing and use in a three-person group decision-making task. Information was distributed in order to create a hidden profile so that disconfirmation of group members' initial preferences was required to solve the task. Experiment 1 revealed that competition, compared to cooperation, led group members to withhold unshared information, a difference that was not significant for shared information. In competition, compared to cooperation, group members were also more reluctant to disconfirm their initial preferences. Decision quality was lower in competition than in cooperation, this effect being mediated by disconfirmation use and not by information sharing. Experiment 2 replicated these findings and revealed the role of mistrust in predicting strategic information sharing and use in competition. These results support a motivated information processing approach of group decision making.

Psychologists have repeatedly shown that a single statistical factor--often called "general intelligence"--emerges from the correlations among people's performance on a wide variety of cognitive tasks. But no one has systematically examined whether a similar kind of "collective intelligence" exists for groups of people. In two studies with 699 people, working in groups of two to five, we find converging evidence of a general collective intelligence factor that explains a group's performance on a wide variety of tasks. This "c factor" is not strongly correlated with the average or maximum individual intelligence of group members but is correlated with the average social sensitivity of group members, the equality in distribution of conversational turn-taking, and the proportion of females in the group.

How Knowledge Worker Teams Deal Effectively with Task Uncertainty: The Impact of Transformational Leadership and Group Development.

Leuteritz, Jan-Paul; Navarro, José; Berger, Rita

2017-01-01

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.

Learned helplessness in chess players: the importance of task similarity and the role of skill.

PubMed

Gobet, F R

1992-01-01

The effects of noncontingency between subjects' responses and outcomes were examined with respect to treatment-and-posttest similarity and skill in the task. The experimental design consisted of three groups. The first group had to solve chess problems with objective solutions and received veridical feedback; each member of the second group faced problems with no objective solutions, and received the same feedback as the member of the first group he was yoked with, but without any control on it; the control group received a waiting task. It was found at the end of the experiment that the group with unsolvable problems was more depressed than the two other groups. The mid-strength players were the most sensitive to the manipulation, and the weakest players showed little effect of learned helplessness. It was also found that the effects were proportional to the degree of similarity between the treatment and the posttest. The results limit the domain of applicability of the learned-helplessness model.

Planning and Performance in Small Groups: Collective Implementation Intentions Enhance Group Goal Striving.

Thürmer, J Lukas; Wieber, Frank; Gollwitzer, Peter M

2017-01-01

There are two key motivators to perform well in a group: making a contribution that (a) is crucial for the group (indispensability) and that (b) the other group members recognize (identifiability). We argue that indispensability promotes setting collective ("We") goals whereas identifiability induces individual ("I") goals. Although both goals may enhance performance, they should align with different strategies. Whereas pursuing collective goals should involve more cooperation, pursuing individual goals should involve less cooperation. Two experiments support this reasoning and show that planning out collective goals with collective implementation intentions (cIIs or "We-plans") relies on cooperation but planning out individual goals with individual implementation intentions (IIs or "I-plans") does not. In Experiment 1, three-member groups first formed a collective or an individual goal and then performed a first round of a physical persistence task. Groups then either formed a respective implementation intention (cII or II) or a control plan and then performed a second round of the task. Although groups with cIIs and IIs performed better on a physical persistence task than respective control groups, only cII groups interacted more cooperatively during task performance. To confirm the causal role of these interaction processes, Experiment 2 used the same persistence task and manipulated whether groups could communicate: When communication was hindered, groups with cIIs but not groups with IIs performed worse. Communication thus qualifies as a process making cIIs effective. The present research offers a psychology of action account to small group performance.

Peer effects on risk behaviour: the importance of group identity.

PubMed

Gioia, Francesca

2017-01-01

This paper investigates whether and to what extent group identity plays a role in peer effects on risk behaviour. We run a laboratory experiment in which different levels of group identity are induced through different matching protocols (random or based on individual painting preferences) and the possibility to interact with group members via an online chat in a group task. Risk behaviour is measured by using the Bomb Risk Elicitation Task and peer influence is introduced by giving subjects feedback regarding group members' previous decisions. We find that subjects are affected by their peers when taking decisions and that group identity influences the magnitude of peer effects: painting preferences matching significantly reduces the heterogeneity in risk behaviour compared with random matching. On the other hand, introducing a group task has no significant effect on behaviour, possibly because interaction does not always contribute to enhancing group identity. Finally, relative riskiness within the group matters and individuals whose peers are riskier than they are take on average riskier decisions, even when controlling for regression to the mean.

Cognitive synergy in groups and group-to-individual transfer of decision-making competencies

In a field study (148 participants organized in 38 groups) we tested the effect of group synergy and one's position in relation to the collaborative zone of proximal development (CZPD) on the change of individual decision-making competencies. We used two parallel sets of decision tasks reported in previous research to test rationality and we evaluated individual decision-making competencies in the pre-group and post-group conditions as well as group rationality (as an emergent group level phenomenon). We used multilevel modeling to analyze the data and the results showed that members of synergetic groups had a higher cognitive gain as compared to members of non-synergetic groups, while highly rational members (members above the CZPD) had lower cognitive gains compared to less rational group members (members situated below the CZPD). These insights extend the literature on group-to-individual transfer of learning and have important practical implications as they show that group dynamics influence the development of individual decision-making competencies.

Ellis, Wendy; Zarbatany, Lynne; Chen, Xinyin; Kinal, Megan; Boyko, Lisa

2018-01-01

Peer group interactional style was examined as a moderator of the relation between peer group school misconduct and group members' school misconduct. Participants were 705 students (M age  = 11.59 years, SD = 1.37) in 148 peer groups. Children reported on their school misconduct in fall and spring. In the winter, group members were observed in a limited-resource task and a group conversation task, and negative and positive group interactional styles were assessed. Multilevel modeling indicated that membership in groups that were higher on school misconduct predicted greater school misconduct only when the groups were high on negative or low on positive interactional style. Results suggest that negative laughter and a coercive interactional style may intensify group effects on children's misconduct. © 2017 The Authors.

The Name-Letter-Effect in Groups: Sharing Initials with Group Members Increases the Quality of Group Work

Polman, Evan; Pollmann, Monique M. H.; Poehlman, T. Andrew

2013-01-01

Although the name-letter-effect has been demonstrated reliably in choice contexts, recent research has called into question the existence of the name-letter-effect–the tendency among people to make choices that bear remarkable similarity with the letters in their own name. In this paper, we propose a connection between the name-letter-effect and interpersonal, group-level behavior that has not been previously captured in the literature. Specifically, we suggest that sharing initials with other group members promotes positive feelings toward those group members that in turn affect group outcomes. Using both field and laboratory studies, we found that sharing initials with group members cause groups to perform better by demonstrating greater performance, collective efficacy, adaptive conflict, and accuracy (on a hidden-profile task). Although many studies have investigated the effects of member similarity on various outcomes, our research demonstrates how minimal a degree of similarity among members is sufficient to influence quality of group outcomes.

Neural mechanisms tracking popularity in real-world social networks.

Zerubavel, Noam; Bearman, Peter S; Weber, Jochen; Ochsner, Kevin N

2015-12-08

Differences in popularity are a key aspect of status in virtually all human groups and shape social interactions within them. Little is known, however, about how we track and neurally represent others' popularity. We addressed this question in two real-world social networks using sociometric methods to quantify popularity. Each group member (perceiver) viewed faces of every other group member (target) while whole-brain functional MRI data were collected. Independent functional localizer tasks were used to identify brain systems supporting affective valuation (ventromedial prefrontal cortex, ventral striatum, amygdala) and social cognition (dorsomedial prefrontal cortex, precuneus, temporoparietal junction), respectively. During the face-viewing task, activity in both types of neural systems tracked targets' sociometric popularity, even when controlling for potential confounds. The target popularity-social cognition system relationship was mediated by valuation system activity, suggesting that observing popular individuals elicits value signals that facilitate understanding their mental states. The target popularity-valuation system relationship was strongest for popular perceivers, suggesting enhanced sensitivity to differences among other group members' popularity. Popular group members also demonstrated greater interpersonal sensitivity by more accurately predicting how their own personalities were perceived by other individuals in the social network. These data offer insights into the mechanisms by which status guides social behavior.

Task-switching costs promote the evolution of division of labor and shifts in individuality

2012-01-01

From microbes to humans, the success of many organisms is achieved by dividing tasks among specialized group members. The evolution of such division of labor strategies is an important aspect of the major transitions in evolution. As such, identifying specific evolutionary pressures that give rise to group-level division of labor has become a topic of major interest among biologists. To overcome the challenges associated with studying this topic in natural systems, we use actively evolving populations of digital organisms, which provide a unique perspective on the de novo evolution of division of labor in an open-ended system. We provide experimental results that address a fundamental question regarding these selective pressures: Does the ability to improve group efficiency through the reduction of task-switching costs promote the evolution of division of labor? Our results demonstrate that as task-switching costs rise, groups increasingly evolve division of labor strategies. We analyze the mechanisms by which organisms coordinate their roles and discover strategies with striking biological parallels, including communication, spatial patterning, and task-partitioning behaviors. In many cases, under high task-switching costs, individuals cease to be able to perform tasks in isolation, instead requiring the context of other group members. The simultaneous loss of functionality at a lower level and emergence of new functionality at a higher level indicates that task-switching costs may drive both the evolution of division of labor and also the loss of lower-level autonomy, which are both key components of major transitions in evolution.

This paper presents a conceptual approach for leading various types of groups of chronically mentally ill patients. Although these groups may have a concrete, task-oriented purpose, with skillful leadership they also function as psychotherapy groups. The developmental deficits in ego functions, object relations, and social skills that severely impair such groups can be compensated by non-interpretative actions of the therapists. The group leader must actively work to provide for the structure, stability, and safety of the group when group members are unable to provide these for themselves. PMID:4049917

The process of developing evidence-based guidance in medicine and public health: a qualitative study of views from the inside

PubMed Central

2013-01-01

Background There has been significant investment in developing guidelines to improve clinical and public health practice. Though much is known about the processes of evidence synthesis and evidence-based guidelines implementation, we know little about how evidence presented to advisory groups is interpreted and used to form practice recommendations or what happens where evidence is lacking. This study investigates how members of advisory groups of NICE (National Institute of Health and Clinical Excellence) conceptualize evidence and experience the process. Methods Members of three advisory groups for acute physical, mental and public health were interviewed at the beginning and end of the life of the group. Seventeen were interviewed at both time points; five were interviewed just once at time one; and 17 were interviewed only once after guidance completion. Using thematic and content analysis, interview transcripts were analysed to identify the main themes. Results Three themes were identified: 1. What is the task? Different members conceptualized the task differently; some emphasized the importance of evidence at the top of the quality hierarchy while others emphasized the importance of personal experience. 2. Who gets heard? Managing the diversity of opinion and vested interests was a challenge for the groups; service users were valued and as was the importance of fostering good working relationships between group members. 3. What is the process? Group members valued debate and recognized the need to marshal discussion; most members were satisfied with the process and output. Conclusions Evidence doesn’t form recommendations on its own, but requires human judgement. Diversity of opinion within advisory groups was seen as key to making well-informed judgments relevant to forming recommendations. However, that diversity can bring tensions in the evaluation of evidence and its translation into practice recommendations. PMID:24006933

Biased information search in homogeneous groups: confidence as a moderator for the effect of anticipated task requirements.

Kerschreiter, Rudolf; Schulz-Hardt, Stefan; Mojzisch, Andreas; Frey, Dieter

2008-05-01

When searching for information, groups that are homogeneous regarding their members' prediscussion decision preferences show a strong bias for information that supports rather than conflicts with the prevailing opinion (confirmation bias). The present research examined whether homogeneous groups blindly search for information confirming their beliefs irrespective of the anticipated task or whether they are sensitive to the usefulness of new information for this forthcoming task. Results of three experiments show that task sensitivity depends on the groups' confidence in the correctness of their decision: Moderately confident groups displayed a strong confirmation bias when they anticipated having to give reasons for their decision but showed a balanced information search or even a dis confirmation bias (i.e., predominately seeking conflicting information) when they anticipated having to refute counterarguments. In contrast, highly confident groups demonstrated a strong confirmation bias independent of the anticipated task requirements.

Ensemble perception in autism spectrum disorder: Member-identification versus mean-discrimination.

PubMed

Van der Hallen, Ruth; Lemmens, Lisa; Steyaert, Jean; Noens, Ilse; Wagemans, Johan

2017-07-01

To efficiently represent the outside world our brain compresses sets of similar items into a summarized representation, a phenomenon known as ensemble perception. While most studies on ensemble perception investigate this perceptual mechanism in typically developing (TD) adults, more recently, researchers studying perceptual organization in individuals with autism spectrum disorder (ASD) have turned their attention toward ensemble perception. The current study is the first to investigate the use of ensemble perception for size in children with and without ASD (N = 42, 8-16 years). We administered a pair of tasks pioneered by Ariely [2001] evaluating both member-identification and mean-discrimination. In addition, we varied the distribution types of our sets to allow a more detailed evaluation of task performance. Results show that, overall, both groups performed similarly in the member-identification task, a test of "local perception," and similarly in the mean identification task, a test of "gist perception." However, in both tasks performance of the TD group was affected more strongly by the degree of stimulus variability in the set, than performance of the ASD group. These findings indicate that both TD children and children with ASD use ensemble statistics to represent a set of similar items, illustrating the fundamental nature of ensemble coding in visual perception. Differences in sensitivity to stimulus variability between both groups are discussed in relation to recent theories of information processing in ASD (e.g., increased sampling, decreased priors, increased precision).

What makes a 'good group'? Exploring the characteristics and performance of undergraduate student groups.

Channon, S B; Davis, R C; Goode, N T; May, S A

2017-03-01

Group work forms the foundation for much of student learning within higher education, and has many educational, social and professional benefits. This study aimed to explore the determinants of success or failure for undergraduate student teams and to define a 'good group' through considering three aspects of group success: the task, the individuals, and the team. We employed a mixed methodology, combining demographic data with qualitative observations and task and peer evaluation scores. We determined associations between group dynamic and behaviour, demographic composition, member personalities and attitudes towards one another, and task success. We also employed a cluster analysis to create a model outlining the attributes of a good small group learning team in veterinary education. This model highlights that student groups differ in measures of their effectiveness as teams, independent of their task performance. On the basis of this, we suggest that groups who achieve high marks in tasks cannot be assumed to have acquired team working skills, and therefore if these are important as a learning outcome, they must be assessed directly alongside the task output.

The Insensitive Ruins It All: Compositional and Compilational Influences of Social Sensitivity on Collective Intelligence in Groups.

PubMed

Meslec, Nicoleta; Aggarwal, Ishani; Curseu, Petru L

2016-01-01

A group's collective intelligence reflects its capacity to perform well across a variety of cognitive tasks and it transcends the individual intelligence of its members. Previous research shows that group members' social sensitivity is a potential antecedent of collective intelligence, yet it is still unclear whether individual or group-level indices are responsible for the positive association between social sensitivity and collective intelligence. In a comprehensive manner, we test the extent to which both compositional (lowest and highest individual score) and compilational aspects (emergent group level) of social sensitivity are associated with collective intelligence. This study has implications for research that explores groups as information processors, and for group design as it indicates how a group should be composed with respect to social sensitivity if the group is to reach high levels of collective intelligence. Our empirical results indicate that collectively intelligent groups are those in which the least socially sensitive group member has a rather high score on social sensitivity. Differently stated, (socially sensitive) group members cannot compensate for the lack of social sensitivity of the other group members.

Social identity influences stress appraisals and cardiovascular reactions to acute stress exposure.

PubMed

Gallagher, Stephen; Meaney, Sarah; Muldoon, Orla T

2014-09-01

This study tested a recent theoretical development in stress research to see whether group membership influenced cardiovascular reactions following exposure to acute stress. Participants (N = 104) were exposed to a message in which a maths test was described as stressful or challenging by an ingroup member (a student) or outgroup member (a stress disorder sufferer). Systolic blood pressure and diastolic blood pressure(DBP) and heart rate (HR) were monitored throughout a standard reactivity study. As expected, a significant interaction was found; relative to those who were told that the task was challenging, ingroup members reported more stress and had higher DBP and HR reactivity when told by an ingroup member that the maths task was stressful; task information did not have the same effect for outgroup members. These results indicate that informational support is not constant but varies as a function of group membership. Finally, this recent development in stress research may prove useful for those interested in investigating the interactions between social, psychological and physiological processes underlying health disparities. What is already known on this subject? Stress is a common risk factor for hypertension and coronary heart disease. Social support has been found to reduce cardiovascular reactions to acute psychological stress. The influence of social support on stress varies as a consequence of social identity. What does this study add? The social group that one belongs to influences how one appraises and responds to stress. Social identity provides a useful framework for understanding how social processes are associated with health disparities. © 2013 The British Psychological Society.

Data was collected from 187 nurses distributed in eight units in a mid-western hospital in the USA. Hierarchical linear modeling was used to analyze the cross-level interaction of leader-member exchange variability and task interdependence on individual-level perceptions of justice. Leader-member exchange variability was significantly related to distributive justice and interactional justice but not significantly related to procedural justice. The interaction term was significantly related to interpersonal justice, but not to procedural justice or distributive justice. This study showed that if leaders demonstrated a variation in treatment of different subordinates, nurses could perceive this as unfair regarding distribution and interaction; when the group was highly task interdependent, this kind of perception of 'unfairness,' particularly regarding interpersonal treatment, became even more salient. Preferential and inconsistent treatment by them within the work group could introduce nurses' perceptions of unfair treatment. It is of crucial importance to provide training for supervisors on how to display relatively consistent behaviour towards nurses, particularly when the teams are highly task interdependent. © 2012 John Wiley & Sons Ltd.

In the present study, the in-group bias or in-group derogation among Mainland Chinese was investigated through a rating task and a recognition test. In two experiments,participants from two universities with similar ranks rated novel faces or names and then had a recognition test. Half of the faces or names were labeled as participants' own university and the other half were labeled as their counterpart. Results showed that, for either faces or names, rating scores for out-group members were consistently higher than those for in-group members, whereas the recognition accuracy showed just the opposite. These results indicated that the attitude and memory for group-relevant information might be dissociated among Mainland Chinese.

In robotic surgery, the professional ergonomic habit of using an armrest reduces operator fatigue and increases the precision of motion. We designed and validated a pressure surveillance system (PSS) based on force sensors to investigate armrest use. The objective was to evaluate whether adding an alarm to the PSS system could shorten ergonomic training and improve performance. Twenty robot and simulator-naïve participants were recruited and randomized in two groups (A and B). The PSS was installed on a robotic simulator, the dV-Trainer, to detect contact with the armrest. The Group A members completed three tasks on the dV-Trainer without the alarm, making 15 attempts at each task. The Group B members practiced the first two tasks with the alarm and then completed the final tasks without the alarm. The simulator provided an overall score reflecting the trainees' performance. We used the new concept of an "armrest load" score to describe the ergonomic habit of using the armrest. Group B had a significantly higher performance score (p < 0.001) and armrest load score (p < 0.001) than Group A from the fifth attempt of the first task to the end of the experiment. Based on the conditioned reflex effect, the alarm associated with the PSS rectified ergonomic errors and accelerated professional ergonomic habit acquisition. The combination of the PSS and alarm is effective in significantly shortening the learning curve in the robotic training process.

Affective expressions in groups and inferences about members' relational well-being: The effects of socially engaging and disengaging emotions.

PubMed

Rothman, Naomi B; Magee, Joe C

2016-01-01

Our findings draw attention to the interpersonal communication function of a relatively unexplored dimension of emotions-the level of social engagement versus disengagement. In four experiments, regardless of valence and target group gender, observers infer greater relational well-being (more cohesiveness and less conflict) between group members from socially engaging (sadness and appreciation) versus disengaging (anger and pride) emotion expressions. Supporting our argument that social (dis)engagement is a critical dimension communicated by these emotions, we demonstrate (1) that inferences about group members' self-interest mediate the effect of socially engaging emotions on cohesiveness and (2) that the influence of socially disengaging emotion expressions on inferences of conflict is attenuated when groups have collectivistic norms (i.e., members value a high level of social engagement). Furthermore, we show an important downstream consequence of these inferences of relational well-being: Groups that seem less cohesive because of their members' proud (versus appreciative) expressions are also expected to have worse task performance.

Spouses of returning Iraq (Operation Iraqi Freedom, OIF) and Afghanistan (Operation Enduring Freedom, OEF) military service members report increased depression and anxiety post deployment as they work to reintegrate the family and service member. Reconnecting the family, renegotiating roles that have shifted, reestablishing communication patterns, and dealing with mental health concerns are all tasks that spouses must undertake as part of reintegration. We tested telephone support groups focusing on helping spouses with these basic reintegration tasks. Year-long telephone support groups focused on education, skills building (communication skills, problem solving training, cognitive behavioral techniques, stress management), and support. Spouse depression and anxiety were decreased and perceived social support was increased during the course of the study. In subgroup analyses, spouses with husbands whose injuries caused care difficulties had a positive response to the intervention. However, they were more likely to be depressed, be anxious, and have less social support compared to participants who had husbands who had no injury or whose injury did not cause care difficulty. Study findings suggest that this well-established, high-access intervention can help improve quality of life for military spouses who are struggling with reintegration of the service member and family.

Group heterogeneity increases the risks of large group size: a longitudinal study of productivity in research groups.

Heterogeneous groups are valuable, but differences among members can weaken group identification. Weak group identification may be especially problematic in larger groups, which, in contrast with smaller groups, require more attention to motivating members and coordinating their tasks. We hypothesized that as groups increase in size, productivity would decrease with greater heterogeneity. We studied the longitudinal productivity of 549 research groups varying in disciplinary heterogeneity, institutional heterogeneity, and size. We examined their publication and citation productivity before their projects started and 5 to 9 years later. Larger groups were more productive than smaller groups, but their marginal productivity declined as their heterogeneity increased, either because their members belonged to more disciplines or to more institutions. These results provide evidence that group heterogeneity moderates the effects of group size, and they suggest that desirable diversity in groups may be better leveraged in smaller, more cohesive units.

This study seeks to explore whether neuroticism, agreeableness, and conscientiousness moderate the influence of relationship conflict experienced in groups on changes in group members' evaluative cognitions related to teamwork quality (teamwork-related mental models). Data from 216 students, nested in 48 groups were analyzed using a multilevel modeling approach. Our results show that the experience of relationship conflict leads to a negative shift from the pre-task to the post-task teamwork-related mental models. Moreover, the results indicate that conscientiousness buffered the negative association between relationship conflict and the change in teamwork-related mental models. Our results did not support the hypothesized moderating effect of agreeableness and show that the detrimental effect of relationship conflict on the shift in teamwork-related mental models is accentuated for group members scoring low rather than high on neuroticism. These findings open new research venues for exploring the association between personality, coping styles and change in teamwork-related mental models.

History-Based Response Threshold Model for Division of Labor in Multi-Agent Systems

PubMed Central

Lee, Wonki; Kim, DaeEun

2017-01-01

Dynamic task allocation is a necessity in a group of robots. Each member should decide its own task such that it is most commensurate with its current state in the overall system. In this work, the response threshold model is applied to a dynamic foraging task. Each robot employs a task switching function based on the local task demand obtained from the surrounding environment, and no communication occurs between the robots. Each individual member has a constant-sized task demand history that reflects the global demand. In addition, it has response threshold values for all of the tasks and manages the task switching process depending on the stimuli of the task demands. The robot then determines the task to be executed to regulate the overall division of labor. This task selection induces a specialized tendency for performing a specific task and regulates the division of labor. In particular, maintaining a history of the task demands is very effective for the dynamic foraging task. Various experiments are performed using a simulation with multiple robots, and the results show that the proposed algorithm is more effective as compared to the conventional model. PMID:28555031

The Power of a "Maverick" in Collaborative Problem Solving: An Experimental Investigation of Individual Perspective-Taking Within a Group.

PubMed

Hayashi, Yugo

2018-05-01

Integrating different perspectives is a sophisticated strategy for developing constructive interactions in collaborative problem solving. However, cognitive aspects such as individuals' knowledge and bias often obscure group consensus and produce conflict. This study investigated collaborative problem solving, focusing on a group member interacting with another member having a different perspective (a "maverick"). It was predicted that mavericks might mitigate disadvantages and facilitate perspective taking during problem solving. Thus, 344 university students participated in two laboratory-based experiments by engaging in a simple rule-discovery task that raised conflicts among perspectives. They interacted with virtual partners whose conversations were controlled by multiple conversational agents. Results show that when participants interacted with a maverick during the task, they were able to take others' perspectives and integrate different perspectives to solve the problem. Moreover, when participants interacted in groups with a positive mood, groups with a maverick outperformed groups having several perspectives. Copyright © 2018 Cognitive Science Society, Inc.

Cooperation during cultural group formation promotes trust towards members of out-groups.

PubMed

Pan, Xiaofei Sophia; Houser, Daniel

People often cooperate with members of their own group, and discriminate against members of other groups. Previous research establishes that cultural groups can form endogenously, and that these groups demonstrate in-group favouritism. Given the presence of cultural groups, the previous literature argues that cultural evolution selects for groups that exhibit parochial altruism. The source of initial variation in these traits, however, remains uninformed. We show here that a group's economic production environment may substantially influence parochial tendencies, with groups formed around more cooperative production (CP) displaying less parochialism than groups formed around more independent production (IP) processes. Participants randomized into CP and IP production tasks formed cultural groups, and subsequently played hidden-action trust games with in-group and out-group trustees. We found CP to be associated with significantly greater sharing and exchanging behaviours than IP. In trust games, significant parochial altruism (in-group favouritism combined with out-group discrimination) was displayed by members of IP groups. By contrast, members of CP groups did not engage in either in-group favouritism or out-group discrimination. Further, we found the absence of out-group discrimination in CP to persist even following 'betrayal'. Finally, belief data suggest that members of CP are not more intrinsically generous than IP members, but rather more likely to believe that out-group trustees will positively reciprocate. Our results have important implications for anyone interested in building cooperative teams, and shed new light on connections between culture and cooperation.

The effects of legacy organization culture on post-merger integration.

PubMed

Frantz, Terrill L; Carley, Kathleen M

2013-01-01

We explore the relationship between the characteristics of pre-existing organization cultures and post-merger integration dynamics; this study involves examining data produced by computer simulation. Two characteristics of organization culture, its characteristic complexity and its propensity for members' to share information, are controlled in computational experiments. To characterize post-merger integration dynamics, we measure the transfer of information with respect to two types: (a) that which is necessary in performing work tasks, and (b) that which underlies the features of a group's culture. The extent to which this information is common in a group is indicative of task performance and the cultural cohesiveness of its members; leading to the level of performance for the group. We consider cultural knowledge as it pertains to both that of the entire organization and at the work-team level; often times, these can be dissimilar. We find that cultural complexity and exchange motivation vary in their influence on the diffusion of task and cultural knowledge: the more complex the culture, the longer for post-merger integration to complete, while simultaneously task performance suffers. However, the inclination for an organization to energetically share their culture with another group does not immensely impact the diffusion of cultural or task knowledge; moreover, high levels of task focus in a culture can hinder cultural diffusion, though performance is positively correlated with this characteristic. This study has relevance to post-merger integration research and practice by providing a theoretically grounded, quantitative model useful for estimating the post-merger dynamics of cultural awareness and knowledge diffusion for a specific merger situation.

A selective review of research highlights the emerging view of groups as information processors. In this review, the authors include research on processing objectives, attention, encoding, storage, retrieval, processing, response, feedback, and learning in small interacting task groups. The groups as information processors perspective underscores several characteristic dimensions of variability in group performance of cognitive tasks, namely, commonality-uniqueness of information, convergence-diversity of ideas, accentuation-attenuation of cognitive processes, and belongingness-distinctiveness of members. A combination of contributions framework provides an additional conceptualization of information processing in groups. The authors also address implications, caveats, and questions for future research and theory regarding groups as information processors.

Drawing on classic social identity theorizing (Tajfel, Differentiation between social groups: Studies in the social psychology of intergroup relations, London, UK, Academic Press, 1978), we propose that low-status minority group members' self-efficacy and performance on intellectual tasks can be enhanced by prompting them to believe in a better future for their group (i.e., increasing awareness of cognitive alternatives to the existing low-status position). Study 1 manipulated cognitive alternatives among 157 migrant workers' children in China, showing that self-efficacy was enhanced in the high compared to the low cognitive alternative condition. Study 2 extended this experimental finding among 114 migrant workers' children: Participants in the high cognitive alternative condition performed better on mathematics and attention tasks than did participants in the low cognitive alternative condition. Results highlight the power of believing in a better future for the collective as a means of enhancing self-efficacy and educational outcomes among members of disadvantaged groups. © 2017 The British Psychological Society.

Psychological collectivism: a measurement validation and linkage to group member performance.

PubMed

Jackson, Christine L; Colquitt, Jason A; Wesson, Michael J; Zapata-Phelan, Cindy P

2006-07-01

The 3 studies presented here introduce a new measure of the individual-difference form of collectivism. Psychological collectivism is conceptualized as a multidimensional construct with the following 5 facets: preference for in-groups, reliance on in-groups, concern for in-groups, acceptance of in-group norms, and prioritization of in-group goals. Study 1 developed and tested the new measure in a sample of consultants. Study 2 cross-validated the measure using an alumni sample of a Southeastern university, assessing its convergent validity with other collectivism measures. Study 3 linked scores on the measure to 4 dimensions of group member performance (task performance, citizenship behavior, counterproductive behavior, and withdrawal behavior) in a computer software firm and assessed discriminant validity using the Big Five. The results of the studies support the construct validity of the measure and illustrate the potential value of collectivism as a predictor of group member performance.

Fostering group identification and creativity in diverse groups: the role of individuation and self-verification.

Swann, William B; Kwan, Virginia S Y; Polzer, Jeffrey T; Milton, Laurie P

2003-11-01

A longitudinal study examined the interplay of identity negotiation processes and diversity in small groups of master's of business administration (MBA) students. When perceivers formed relatively positive impressions of other group members, higher diversity predicted more individuation of targets. When perceivers formed relatively neutral impressions of other group members, however, higher diversity predicted less individuation of targets. Individuation at the outset of the semester predicted self-verification effects several weeks later, and self-verification, in turn, predicted group identification and creative task performance. The authors conclude that contrary to self-categorization theory, fostering individuation and self-verification in diverse groups may maximize group identification and productivity.

Neural mechanisms tracking popularity in real-world social networks

2015-01-01

Differences in popularity are a key aspect of status in virtually all human groups and shape social interactions within them. Little is known, however, about how we track and neurally represent others’ popularity. We addressed this question in two real-world social networks using sociometric methods to quantify popularity. Each group member (perceiver) viewed faces of every other group member (target) while whole-brain functional MRI data were collected. Independent functional localizer tasks were used to identify brain systems supporting affective valuation (ventromedial prefrontal cortex, ventral striatum, amygdala) and social cognition (dorsomedial prefrontal cortex, precuneus, temporoparietal junction), respectively. During the face-viewing task, activity in both types of neural systems tracked targets’ sociometric popularity, even when controlling for potential confounds. The target popularity–social cognition system relationship was mediated by valuation system activity, suggesting that observing popular individuals elicits value signals that facilitate understanding their mental states. The target popularity–valuation system relationship was strongest for popular perceivers, suggesting enhanced sensitivity to differences among other group members’ popularity. Popular group members also demonstrated greater interpersonal sensitivity by more accurately predicting how their own personalities were perceived by other individuals in the social network. These data offer insights into the mechanisms by which status guides social behavior. PMID:26598684

2014-03-01

Recent event related brain potential research observed a greater frontal activity to pain expressions of racial in-group than out-group members and such racial bias in neural responses to others' suffering was modulated by task demands that emphasize race identity or painful feeling. However, as pain expressions activate multiple brain regions in the pain matrix, it remains unclear which part of the neural circuit in response to others' suffering undergoes modulations by task demands. We scanned Chinese adults, using functional MRI, while they categorized Asian and Caucasian faces with pain or neutral expressions in terms of race or identified painful feelings of each individual face. We found that pain vs. neutral expressions of Asian but not Caucasian faces activated the anterior cingulate (ACC) and anterior insular (AI) activity during race judgments. However, pain compared to race judgments increased ACC and AI activity to pain expressions of Caucasian but not Asian faces. Moreover, race judgments induced increased activity in the dorsal medial prefrontal cortex whereas pain judgments increased activity in the bilateral temporoparietal junction. The results suggest that task demands emphasizing an individual's painful feeling increase ACC/AI activities to pain expressions of racial out-group members and reduce the racial bias in empathic neural responses. © 2013.

Scalable Authenticated Tree Based Group Key Exchange for Ad-Hoc Groups

Desmedt, Yvo; Lange, Tanja; Burmester, Mike

Task-specific groups are often formed in an ad-hoc manner within large corporate structures, such as companies. Take the following typical scenario: A director decides to set up a task force group for some specific project. An order is passed down the hierarchy where it finally reaches a manager who selects some employees to form the group. The members should communicate in a secure way and for efficiency, a symmetric encryption system is chosen. To establish a joint secret key for the group, a group key exchange (GKE) protocol is used. We show how to use an existing Public Key Infrastructure (PKI) to achieve authenticated GKE by modifying the protocol and particularly by including signatures.

The effects of gender composition on women's experience in math work groups.

2017-06-01

The present studies tested a model outlining the effects of group gender composition on self- and others' perceptions of women's math ability in a truly interactive setting with groups composed entirely of naïve participants (N = 158 4-person groups across 3 studies). One woman in each group was designated to be the "expert" by having her complete a tutorial that gave her task-relevant knowledge for a subsequent group task. Group gender composition was hypothesized to influence perceptions of women's math ability through intrapersonal processes (stereotype threat effects on performance) and interpersonal processes (social cohesion between the expert and other group members). Group composition affected the experts' performance in the group math task, but importantly, it also affected their social cohesion with group members. Moreover, both of these effects-lowered performance and poorer social cohesion in male-dominated groups-made independent contributions in accounting for group gender composition effects on perceptions of women's math ability (Studies 1 and 2). Boundary conditions were examined in a 3rd study. Women who had a history of excelling in math and had chosen a math-intensive STEM major were selected to be the designated experts. We predicted and found this would be sufficient to eliminate the effect of group gender composition on interpersonal processes, and correspondingly the effect on women's perceived math ability. Interestingly (and consistent with past work on stereotype threat effects among highly domain-identified individuals), there were continued performance differences indicative of effects on intrapersonal processes.

Little research has been done on therapeutic alliance in group psychotherapy, especially the impact of treatment duration and therapist professional characteristics. Therapeutic alliance was rated by patients on the Working Alliance Inventory-Short Form at three time points (sessions 3, 10 and 17) in a randomized controlled trial of short-term and long-term psychodynamic group psychotherapy. As predictors we selected therapist clinical experience and length of didactic training, which have demonstrated ambiguous results in previous research. Linear latent variable growth curve models (structural equation modeling) were developed for the three Working Alliance Inventory-Short Form subscales bond, task and goal. We found a significant variance in individual growth curves (intercepts and slopes) but no differential development due to group length. Longer therapist formal training had a negative impact on early values of subscale task in both treatments. There was an interaction between length of the therapists' clinical experience and group length on early bond, task and goal: therapists with longer clinical experience were rated lower on initial bond in the long-term group but less so in the short-term group. Longer clinical experience influenced initial task and goal positively in the short-term group but was unimportant for task or significantly negative for goal in the long-term group. There was no mean development of alliance, and group length did not differentially impact the alliance during 6 months. Early ratings of the three Working Alliance Inventory-Short Form subscales partly reflected different preparations of patients in the two group formats, partly therapist characteristics, but more research is needed to see how these aspects impact alliance development and outcome. Therapists should pay attention to all three aspects of the alliance, when they prepare patients for group therapy. In psychodynamic groups, length of therapy does not differentiate the overall level or the development of member-leader alliance. Within psychodynamic groups, each individual appear to have their unique perception of the member-leader alliance. Therapists with longer formal psychotherapy training may be less successful in establishing early agreement with patients on the tasks of psychodynamic group psychotherapy. Patients perceive a somewhat lower degree of early emotional bonding with the more clinically experienced therapists in long-term psychodynamics groups. Therapists with more clinical experience may contribute to a stronger degree of initial agreement with patients on the tasks and goals of short-term group psychotherapy.

Social Familiarity Reduces Reaction Times and Enhances Survival of Group-Living Predatory Mites under the Risk of Predation

PubMed Central

Strodl, Markus Andreas; Schausberger, Peter

2012-01-01

Background Social familiarity, which is based on the ability to recognise familiar conspecific individuals following prior association, may affect all major life activities of group-living animals such as foraging, reproduction and anti-predator behaviours. A scarcely experimentally tested explanation why social familiarity is beneficial for group-living animals is provided by limited attention theory. Limited attention theory postulates that focusing on a given task, such as inspection and assessment of unfamiliar group members, has cognitive and associated physiological and behavioural costs with respect to the attention paid to other tasks, such as anti-predator vigilance and response. Accordingly, we hypothesised that social familiarity enhances the anti-predator success of group-living predatory mites, Phytoseiulus persimilis, confronted with an intraguild predator, the predatory mite Amblyseius andersoni. Methodology/Principal Findings We videotaped and analysed the response of two P. persimilis larvae, held in familiar or unfamiliar pairs, to attacks by a gravid A. andersoni female, using the behavioural analyses software EthoVision Pro®. Familiar larvae were more frequently close together, reacted more quickly to predator attacks, survived more predator encounters and survived longer than unfamiliar larvae. Significance In line with the predictions of limited attention theory, we suggest that social familiarity improves anti-predator behaviours because it allows prey to shift attention to other tasks rather than group member assessment.

The members of the WGPSN and its task groups have worked since the early 1970s to provide a clear, unambiguous system of planetary nomenclature that represents cultures and countries from all regions of Earth. WGPSN members include Rita Schulz (Chair) and 9 other members representing countries around the globe. The participation of knowledgeable scientists and experts in this process is vital to its success of the IAU WGPSN . Planetary nomenclature is a tool used to uniquely identify features on the surfaces of planets or satellites so they can be located, described, and discussed in publications, including peer-review journals, maps and conference presentations. Approved names are listed in the Transactions of the IAU and on the Gazetteer of Planetary Nomenclature website. Any names currently in use that are not listed the Gazetteer are not official. Planetary names must adhere to rules and conventions established by the IAU WGPSN (see http://planetarynames.wr.usgs.gov/Page/Rules for the complete list). The gazetteer includes an online Name Request Form (http://planetarynames.wr.usgs.gov/FeatureNameRequest) that can be used by members of the professional science community. Name requests are first reviewed by one of six task groups (Mercury, Venus, Moon, Mars, Outer Solar System, and Small Bodies). After a task group has reviewed a proposal, it is submitted to the WGPSN. Allow four to six weeks for the review and approval process. Upon WGPSN approval, names are considered formally approved and it is then appropriate to use them in publications. Approved names are immediately entered into the database and shown on the website. Questions about the nomenclature database and the naming process can be sent to Rosalyn Hayward, USGS Astrogeology Science Center, 2255 N. Gemini Dr., Flagstaff, AZ 86001, or by email to rhayward@usgs.gov.

A Secure Multicast Framework in Large and High-Mobility Network Groups

NASA Astrophysics Data System (ADS)

Lee, Jung-San; Chang, Chin-Chen

With the widespread use of Internet applications such as Teleconference, Pay-TV, Collaborate tasks, and Message services, how to construct and distribute the group session key to all group members securely is becoming and more important. Instead of adopting the point-to-point packet delivery, these emerging applications are based upon the mechanism of multicast communication, which allows the group member to communicate with multi-party efficiently. There are two main issues in the mechanism of multicast communication: Key Distribution and Scalability. The first issue is how to distribute the group session key to all group members securely. The second one is how to maintain the high performance in large network groups. Group members in conventional multicast systems have to keep numerous secret keys in databases, which makes it very inconvenient for them. Furthermore, in case that a member joins or leaves the communication group, many involved participants have to change their own secret keys to preserve the forward secrecy and the backward secrecy. We consequently propose a novel version for providing secure multicast communication in large network groups. Our proposed framework not only preserves the forward secrecy and the backward secrecy but also possesses better performance than existing alternatives. Specifically, simulation results demonstrate that our scheme is suitable for high-mobility environments.

Nonlinear effects of team tenure on team psychological safety climate and climate strength: Implications for average team member performance.

PubMed

Koopmann, Jaclyn; Lanaj, Klodiana; Wang, Mo; Zhou, Le; Shi, Junqi

2016-07-01

The teams literature suggests that team tenure improves team psychological safety climate and climate strength in a linear fashion, but the empirical findings to date have been mixed. Alternatively, theories of group formation suggest that new and longer tenured teams experience greater team psychological safety climate than moderately tenured teams. Adopting this second perspective, we used a sample of 115 research and development teams and found that team tenure had a curvilinear relationship with team psychological safety climate and climate strength. Supporting group formation theories, team psychological safety climate and climate strength were higher in new and longer tenured teams compared with moderately tenured teams. Moreover, we found a curvilinear relationship between team tenure and average team member creative performance as partially mediated by team psychological safety climate. Team psychological safety climate improved average team member task performance only when team psychological safety climate was strong. Likewise, team tenure influenced average team member task performance in a curvilinear manner via team psychological safety climate only when team psychological safety climate was strong. We discuss theoretical and practical implications and offer several directions for future research. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

The Coal Ash Resources Research Consortium{reg_sign} (CARRC{reg_sign}, pronounced 'cars') is the core coal combustion product (CCP) research group at the Energy & Environmental Research Center (EERC). CARRC focuses on performing fundamental and applied scientific and engineering research emphasizing the environmentally safe, economical use of CCPs. CARRC member organizations, which include utilities and marketers, are key to developing industry-driven research in the area of CCP utilization and ensuring its successful application. The U.S. Department of Energy is a partner in CARRC through the EERC Jointly Sponsored Research Program, which provides matching funds for industrial member contributions and facilitates an increased levelmore » of effort in CARRC. CARRC tasks were designed to provide information on CCP performance, including environmental performance, engineering performance, favorable economics, and improved life cycle of products and projects. CARRC technical research tasks are developed based on member input and prioritization. CARRC special projects are developed with members and nonmembers to provide similar information and to support activities, including the assembly and interpretation of data, support for standards development and technology transfer, and facilitating product development and testing. CARRC activities from 2007 to 2009 included a range of research tasks, with primary work performed in laboratory tasks developed to answer specific questions or evaluate important fundamental properties of CCPs. The tasks were included in four categories: (1) Environmental Evaluations of CCPs; (2) Evaluation of Impacts on CCPs from Emission Controls; (3) Construction and Product-Related Activities; and (4) Technology Transfer and Maintenance Tasks. All tasks are designed to work toward achieving the CARRC overall goal and supporting objectives. The various tasks are coordinated in order to provide broad and useful technical data for CARRC members. Special projects provide an opportunity for non-CARRC members to sponsor specific research or technology transfer consistent with CARRC goals. This report covers CARRC activities from January 2007 through March 2009. These activities have been reported in CARRC Annual Reports and in member meetings over the past 2 years. CARRC continues to work with industry and various government agencies with its research, development, demonstration, and promotional activities nearing completion at the time of submission of this report. CARRC expects to continue its service to the coal ash industry in 2009 and beyond to work toward the common goal of advancing coal ash utilization by solving CCP-related technical issues and promoting the environmentally safe, technically sound, and economically viable management of these complex and changing materials.« less

Individual deals within teams: Investigating the role of relative i-deals for employee performance.

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.

ESA has established a Planetary Science Archive User Group (PSA-UG), with the task of offering independent advice to ESA's Planetary Science Archive (e.g. Heather et al., 2013). The PSA-UG is an official and independent body that continuously evaluates services and tools provided by the PSA to the community of planetary data scientific users. The group has been tasked with the following top level objectives: a) Advise ESA on future development of the PSA. b) Act as a focus for the interests of the scientific community. c) Act as an advocate for the PSA. d) Monitor the PSA activities. Based on this, the PSA-UG will report through the official ESA channels. Disciplines and subjects represented by PSA-UG members include: Remote Sensing of both Atmosphere and Solid Surfaces, Magnetospheres, Plasmas, Radio Science and Auxilliary data. The composition of the group covers ESA missions populating the PSA both now and in the near future. The first members of the PSA-UG were selected in 2013 and will serve for 3 years, until 2016. The PSA-UG will address the community through workshops, conferences and the internet. Written recommendations will be made to the PSA coordinator, and an annual report on PSA and the PSA-UG activities will be sent to the Solar System Exploration Working Group (SSEWG). Any member of the community and planetary data user can get in touch with individual members of the PSA-UG or with the group as a whole via the contacts provided on the official PSA-UG web-page: http://archives.esac.esa.int/psa/psa-ug The PSA is accessible via: http://archives.esac.esa.int/psa

Coffee with co-workers: role of caffeine on evaluations of the self and others in group settings.

2018-03-01

This research explores the effect of consuming a moderate amount of commercially available caffeinated coffee on an individual's self-evaluated participation in a group activity and subsequent evaluations of the experience. Across two studies, results show that consuming a moderate amount of caffeinated coffee prior to indulging in a group activity enhances an individual's task-relevant participation in the group activity. In addition, subjective evaluations of the participation of other group members and oneself are also positively influenced. Finally, the positive impact of consuming a moderate amount of caffeinated coffee on the evaluation of participation of other group members and oneself is moderated by a sense of an increased level of alertness.

Telling Friend from Foe: Listeners Are Unable to Identify In-Group and Out-Group Members from Heard Laughter.

Ritter, Marie; Sauter, Disa A

2017-01-01

Group membership is important for how we perceive others, but although perceivers can accurately infer group membership from facial expressions and spoken language, it is not clear whether listeners can identify in- and out-group members from non-verbal vocalizations. In the current study, we examined perceivers' ability to identify group membership from non-verbal vocalizations of laughter, testing the following predictions: (1) listeners can distinguish between laughter from different nationalities and (2) between laughter from their in-group, a close out-group, and a distant out-group, and (3) greater exposure to laughter from members of other cultural groups is associated with better performance. Listeners ( n = 814) took part in an online forced-choice classification task in which they were asked to judge the origin of 24 laughter segments. The responses were analyzed using frequentist and Bayesian statistical analyses. Both kinds of analyses showed that listeners were unable to accurately identify group identity from laughter. Furthermore, exposure did not affect performance. These results provide a strong and clear demonstration that group identity cannot be inferred from laughter.

Society members whose research publication during the past 125 yr had an important impact on the discipline of physiology were featured at the American Physiological Society (APS)'s 125th Anniversary symposium. The daunting and challenging task of identifying and selecting significant publications was assumed by the Steering Committee of the History of Physiology Interest Group, who requested recommendations and rationales from all Sections, select Interest Groups, and active senior APS members. The request resulted in recommendations and rationales from nine Sections, one Interest Group, and 28 senior members, identifying 38 publications and 43 members for recognition purposes. The publication recommendations included 5 individuals (Cournand, Erlanger, Gasser, Hubel, and Wiesel) whose research significantly contributed to their selection for the Nobel Prize in Medicine or Physiology, 4 individuals who received multiple recommendations [i.e., Cannon (3), Curran (2), Fenn (3), and Hamilton (2)], and 11 members who had been APS Presidents. Of the recommended articles, 33% were from the American Journal of Physiology, with the earliest being published in 1898 (Cannon) and the latest in 2007 (Sigmund). For the brief oral presentations, the History of Physiology Steering Committee selected the first choices of the Sections or Interest Group, whereas rationales and representation of the membership were used for the presentations by senior members.

The Effects of Long-Duration Spaceflight on Training Retention and Transfer

NASA Technical Reports Server (NTRS)

Barshi, Immanuel; Healy, Alice; Dempsey, Donna L.; McGuire, Kerry M.; Landon, Lauren B.

2018-01-01

Training our crew members for long duration, exploration-class missions will have to maximize long-term retention and transfer of the trained skills. The expected duration of the missions, our inability to predict all the possible tasks the crew will be called upon to perform, and the low training-to-mission time ratio require that the training be maximally effective such that the skills acquired during training will be retained and will be transferrable across a wide range of specific tasks that are different from the particular tasks used during training. However, to be able to design training that can achieve these ambitious goals, we must first understand the ways in which long-duration spaceflight affects training retention and transfer. Current theories of training retention and transfer are largely based on experimental studies conducted at university laboratories using undergraduate students as participants. Furthermore, all such studies have been conducted on Earth. We do not know how well the results of these studies predict the performance of crew members. More specifically, we do not know how well the results of these studies predict the performance of crew members in space and especially during long-duration missions. To address this gap in our knowledge, the current on-going study seeks to test the null hypothesis that performance of university undergraduate students on Earth on training retention and transfer tests do in fact predict accurately the performance of crew members during long-duration spaceflights. To test this hypothesis, the study employs a single 16-month long experimental protocol with 3 different participant groups: undergraduate university students, crew members on the ground, and crew members in space. Results from this study will be presented upon its completion. This poster presents results of study trials of the two tasks used in this study: a data entry task and a mapping task. By researching established training principles, by examining future needs, and by using current practices in spaceflight training as test beds, this research project is mitigating program risks and generating templates and requirements to meet future training needs.

Effect of Blast Injury on Auditory Localization in Military Service Members.

PubMed

Kubli, Lina R; Brungart, Douglas; Northern, Jerry

Among the many advantages of binaural hearing are the abilities to localize sounds in space and to attend to one sound in the presence of many sounds. Binaural hearing provides benefits for all listeners, but it may be especially critical for military personnel who must maintain situational awareness in complex tactical environments with multiple speech and noise sources. There is concern that Military Service Members who have been exposed to one or more high-intensity blasts during their tour of duty may have difficulty with binaural and spatial ability due to degradation in auditory and cognitive processes. The primary objective of this study was to assess the ability of blast-exposed Military Service Members to localize speech sounds in quiet and in multisource environments with one or two competing talkers. Participants were presented with one, two, or three topic-related (e.g., sports, food, travel) sentences under headphones and required to attend to, and then locate the source of, the sentence pertaining to a prespecified target topic within a virtual space. The listener's head position was monitored by a head-mounted tracking device that continuously updated the apparent spatial location of the target and competing speech sounds as the subject turned within the virtual space. Measurements of auditory localization ability included mean absolute error in locating the source of the target sentence, the time it took to locate the target sentence within 30 degrees, target/competitor confusion errors, response time, and cumulative head motion. Twenty-one blast-exposed Active-Duty or Veteran Military Service Members (blast-exposed group) and 33 non-blast-exposed Service Members and beneficiaries (control group) were evaluated. In general, the blast-exposed group performed as well as the control group if the task involved localizing the source of a single speech target. However, if the task involved two or three simultaneous talkers, localization ability was compromised for some participants in the blast-exposed group. Blast-exposed participants were less accurate in their localization responses and required more exploratory head movements to find the location of the target talker. Results suggest that blast-exposed participants have more difficulty than non-blast-exposed participants in localizing sounds in complex acoustic environments. This apparent deficit in spatial hearing ability highlights the need to develop new diagnostic tests using complex listening tasks that involve multiple sound sources that require speech segregation and comprehension.

The Independence and Interdependence of Coacting Observers in Regard to Performance Efficiency, Workload, and Stress in a Vigilance Task.

Funke, Gregory J; Warm, Joel S; Baldwin, Carryl L; Garcia, Andre; Funke, Matthew E; Dillard, Michael B; Finomore, Victor S; Matthews, Gerald; Greenlee, Eric T

We investigated performance, workload, and stress in groups of paired observers who performed a vigilance task in a coactive (independent) manner. Previous studies have demonstrated that groups of coactive observers detect more signals in a vigilance task than observers working alone. Therefore, the use of such groups might be effective in enhancing signal detection in operational situations. However, concern over appearing less competent than one's cohort might induce elevated levels of workload and stress in coactive group members and thereby undermine group performance benefits. Accordingly, we performed the initial experiment comparing workload and stress in observers who performed a vigilance task coactively with those of observers who performed the vigilance task alone. Observers monitored a video display for collision flight paths in a simulated unmanned aerial vehicle control task. Self-reports of workload and stress were secured via the NASA-Task Load Index and the Dundee Stress State Questionnaire, respectively. Groups of coactive observers detected significantly more signals than did single observers. Coacting observers did not differ significantly from those operating by themselves in terms of workload but did in regard to stress; posttask distress was significantly lower for coacting than for single observers. Performing a visual vigilance task in a coactive manner with another observer does not elevate workload above that of observers working alone and serves to attenuate the stress associated with vigilance task performance. The use of coacting observers could be an effective vehicle for enhancing performance efficiency in operational vigilance. © 2016, Human Factors and Ergonomics Society.

Subliminal Gender Stereotypes: Who Can Resist?

PubMed

van Breen, Jolien A; Spears, Russell; Kuppens, Toon; de Lemus, Soledad

2018-05-01

We examine women's responses to subliminal gender stereotypes, that is, stereotypes present outside conscious awareness. Previous research suggests that subtle stereotypes elicit acceptance and assimilation, but we predict that subliminal exposure to gender stereotypes will trigger resistance in some women. Specifically, we expect resistance to occur among women who are relatively strongly identified with feminists, but not with the broader group of women. We predict that resistance takes the form of persistence in stereotypically masculine domains and (implicit) in-group bias. Indeed, we found that subliminal exposure to stereotypes (vs. counter-stereotypes) led women who identify relatively strongly with feminists, but less strongly with women, to (a) persist in a math task, (b) show increased willingness to sacrifice men in a Moral Choice Dilemma task, and (c) show implicit in-group bias on an evaluative priming task. This evidence of resistance suggests that members of devalued groups are more resilient than previously thought.

Implications for the Self Determine Benevolence and Self-Protection in Intergroup Relations.

PubMed

Malloy, Thomas E; Kinney, Lorin

2017-01-01

People often favor groups they belong to over those beyond the in-group boundary. Yet, in-group favoritism does not always occur, and people will sometimes favor an out-group over the in-group. We delineate theoretically when in-group favoritism (i.e., self-protection) and out-group favoritism (i.e., benevolence) should occur. In two experiments, groups' relative status and competence stereotypes were manipulated; groups' outcomes were non-contingent in Experiment 1 and contingent in Experiment 2. When allocating reward, members of a low status group were self-protective, favoring the in-group over the out-group under both non-contingent and contingent outcomes. Those with high status benevolently favored the out-group when outcomes were non-contingent, but were self-protective with contingent outcomes. People were willing to engage in social activities with an out-group member regardless of competence. However, when task collaboration had implications for the self, those with low status preferred competent over less competent out-group members.

Stereotype-based faultlines and out-group derogation in diverse teams: The moderating roles of task stereotypicality and need for cognition.

PubMed

Stanciu, Adrian

2017-01-01

Alignment of individuals on more than one diversity attribute (i.e., faultlines) may lead to intergroup biases in teams, disrupting the efficiency expectancies. Research has yet to examine if this can be a consequence of a stereotypical consistency between social and information attributes of diversity. The present study tests the hypothesis that, in a team with a stereotype-based faultline (a stereotypical consistency between gender and skills), there is increased out-group derogation compared to a team with a stereotype-inconsistent faultline. Furthermore, the study proposes that tasks can activate stereotypes, and the need for cognition dictates whether stereotypes are applied. The findings confirm the hypothesis and additionally provide evidence that tasks that activate gender stereotypes emphasize out-group derogation, especially for team members with low need for cognition.

The role of social facilitation by way of audience effect in select exercise-related variables during an isometric handgrip task was assessed using a mixed design. Fifty three moderately active participants (Mage= 21.76 ± 5.27) were recruited from the Midwestern United States. Participants were randomly assigned to one of two groups: supportive audience or control. Audience members provided positive verbal encouragement to participants in the experimental condition throughout the task performance. Participants in the control group performed the task in the absence of an audience and did not receive any verbal encouragement. Participants provided anxiety ratings pre- and post-task using the State-trait anxiety inventory for adults (STAI). Participants’ ratings of perceived exertion (RPE) and heart rate (HR) were monitored and assessed at 30-second intervals. Upon task completion, sustained effort in the form of time on task was recorded in seconds. A repeated measures analysis of variance (RM ANOVA) revealed that there was a time effect within groups of HR = ( F(2.64, 131.85) = 189.3, p <0.001) and within groups of RPE = (F(2.97, 139.42) = 2189.43 p <0.001). An independent sample T-test revealed significant differences in HR at 0, 30 and 60 seconds between the groups. An independent sample T-test revealed no significant differences in anxiety and RPE between the groups. These results partially support the notion of social facilitation and may have implications for research and practice. PMID:29399254

A Review of the Perceptions of Healthcare Providers and Family Members Toward Family Involvement in Active Adult Patient Care in the ICU.

Liput, Shea A; Kane-Gill, Sandra L; Seybert, Amy L; Smithburger, Pamela L

2016-06-01

The objective of this article is to provide a summary of the perceptions of healthcare providers and family members toward their role in active patient care in the ICU and compare the views of healthcare providers with those of relatives of critically ill patients. The search was conducted using PubMed as the primary search engine and EMBASE as a secondary search engine. Studies were included if they were conducted in the ICU, had an adult patient population, and contained a discussion of active patient care, including perspective or actions of family members or healthcare providers about the active participation. Titles and abstracts of articles identified through PubMed and EMBASE were assessed for relevancy of family involvement. The full article was reviewed of titles and abstracts involving family involvement of care in the ICU to assess if the topic was active care and if the article involved perceptions of healthcare providers or family members. The references of all selected articles were then evaluated for the inclusion of additional studies. Articles including perceptions of healthcare providers were grouped separately from articles including attitudes of family members. Articles that contained the perceptions of both healthcare providers and family members were considered in both groups but were evaluated with each perspective separately. Examples of specific patient care tasks that were mentioned in each article were identified. A positive attitude exists among both family members and providers toward the involvement of family members in active care tasks. Providers and family members share the attitude that a partnership is necessary and that encouragement for family members to participate is essential. The findings in this review support the need for more objective research regarding how families are caring for their loved ones and how family involvement in care is affecting patient and family outcomes.

2011-12-01

The general formulation of the assignment problem consists in the optimal allocation of a given set of tasks to a workforce. This problem is covered by existing literature for different domains such as distributed databases, distributed systems, transportation, packets radio networks, IT outsourcing, and teaching allocation. This paper presents a new version of the assignment problem for the allocation of academic tasks to staff members in departments with long leave opportunities. It presents the description of a workload allocation scheme and its algorithm, for the allocation of an equitable number of tasks in academic departments where long leaves are necessary.

Collective induction without cooperation? Learning and knowledge transfer in cooperative groups and competitive auctions.

PubMed

Maciejovsky, Boris; Budescu, David V

2007-05-01

There is strong evidence that groups perform better than individuals do on intellective tasks with demonstrably correct solutions. Typically, these studies assume that group members share common goals. The authors extend this line of research by replacing standard face-to-face group interactions with competitive auctions, allowing for conflicting individual incentives. In a series of studies involving the well-known Wason selection task, they demonstrate that competitive auctions induce learning effects equally impressive as those of standard group interactions, and they uncover specific and general knowledge transfers from these institutions to new reasoning problems. The authors identify payoff feedback and information pooling as the driving factors underlying these findings, and they explain these factors within the theoretical framework of collective induction.

Contagion and differentiation in unethical behavior: the effect of one bad apple on the barrel.

PubMed

Gino, Francesca; Ayal, Shahar; Ariely, Dan

2009-03-01

In a world where encounters with dishonesty are frequent, it is important to know if exposure to other people's unethical behavior can increase or decrease an individual's dishonesty. In Experiment 1, our confederate cheated ostentatiously by finishing a task impossibly quickly and leaving the room with the maximum reward. In line with social-norms theory, participants' level of unethical behavior increased when the confederate was an in-group member, but decreased when the confederate was an out-group member. In Experiment 2, our confederate instead asked a question about cheating, which merely strengthened the saliency of this possibility. This manipulation decreased the level of unethical behavior among the other group members. These results suggest that individuals' unethicality does not depend on the simple calculations of cost-benefit analysis, but rather depends on the social norms implied by the dishonesty of others and also on the saliency of dishonesty.

Maintaining patients' social contacts through displaying nonverbal awareness information on mobile devices.

Awareness systems had been invented for supporting groups collaborating simultaneously over a network. They provide each group member with real-time information about the state of affairs on the remote locations of the other members. Awareness systems have also been observed to help remote collaborators develop the same shared sense of community that often emerges within co-located work groups, and this effect of creating or maintaining group cohesion is an important goal in itself. Purely social awareness systems can be employed by any kind of group, e.g. families, without shared work tasks. As a means of preventing loneliness they can be regarded as examples of biomedical technology. In this paper a demonstrator of an awareness-enhanced instant messaging system for elderly living alone is described along with assumptions about group processes that led to its specification.

Task versus relationship conflict, team performance, and team member satisfaction: a meta-analysis.

PubMed

De Dreu, Carsten K W; Weingart, Laurie R

2003-08-01

This study provides a meta-analysis of research on the associations between relationship conflict, task conflict, team performance, and team member satisfaction. Consistent with past theorizing, results revealed strong and negative correlations between relationship conflict, team performance, and team member satisfaction. In contrast to what has been suggested in both academic research and introductory textbooks, however, results also revealed strong and negative (instead of the predicted positive) correlations between task conflict team performance, and team member satisfaction. As predicted, conflict had stronger negative relations with team performance in highly complex (decision making, project, mixed) than in less complex (production) tasks. Finally, task conflict was less negatively related to team performance when task conflict and relationship conflict were weakly, rather than strongly, correlated.

ESA has established a Planetary Science Archive User Group (PSA-UG), with the task of offering independent advice to ESA's Planetary Science Archive (e.g. Heather et al., 2013). The PSA-UG is an official and independent body that continuously evaluates services and tools provided by the PSA to the community of planetary data scientific users. The group has been tasked with the following top level objectives: a) Advise ESA on future development of the PSA. b) Act as a focus for the interests of the scientific community. c) Act as an advocate for the PSA. d) Monitor the PSA activities. Based on this, the PSA-UG will report through the official ESA channels. Disciplines and subjects represented by PSA-UG members include: Remote Sensing of both Atmosphere and Solid Surfaces, Magnetospheres, Plasmas, Radio Science and Auxilliary data. The composition of the group covers ESA missions populating the PSA both now and in the near future. The first members of the PSA-UG were selected in 2013 and will serve for 3 years, until 2016. The PSA-UG will address the community through workshops, conferences and the internet. Written recommendations will be made to the PSA coordinator, and an annual report on PSA and the PSA-UG activities will be sent to the Solar System Exploration Working Group (SSEWG). Any member of the community and planetary data user can get in touch with individual members of the PSA-UG or with the group as a whole via the contacts provided on the official PSA-UG web-page: http://archives.esac.esa.int/psa/psa-ug.

2014-01-01

Children prefer learning from, and affiliating with, their racial in-group but those preferences may vary for biracial children. Monoracial (White, Black, Asian) and biracial (Black/White, Asian/White) children (N = 246, 3-8 years) had their racial identity primed. In a learning preferences task, participants determined the function of a novel object after watching adults (White, Black, and Asian) demonstrate its uses. In the social preferences task, participants saw pairs of children (White, Black, and Asian) and chose with whom they most wanted to socially affiliate. Biracial children showed flexibility in racial identification during learning and social tasks. However, minority-primed biracial children were not more likely than monoracial minorities to socially affiliate with primed racial in-group members, indicating their in-group preferences are contextually based. © 2014 The Authors.

Disease-modifying therapies are urgently needed for the treatment of Alzheimer's disease (AD). The European Union/United States (EU/US) Task Force represents a broad range of stakeholders including biopharma industry personnel, academicians, and regulatory authorities. The EU/US Task Force represents a community of knowledgeable individuals who can inform views of evidence supporting disease modification and the development of disease-modifying therapies (DMTs). We queried their attitudes toward clinical trial design and biomarkers in support of DMTs. A survey of members of the EU/US Alzheimer's Disease Task Force was conducted. Ninety-three members (87%) responded. The details were analyzed to understand what clinical trial design and biomarker data support disease modification. Task Force members favored the parallel group design compared to delayed start or staggered withdrawal clinical trial designs to support disease modification. Amyloid biomarkers were regarded as providing mild support for disease modification while tau biomarkers were regarded as providing moderate support. Combinations of biomarkers, particularly combinations of tau and neurodegeneration, were regarded as providing moderate to marked support for disease modification and combinations of all three classes of biomarkers were regarded by a majority as providing marked support for disease modification. Task Force members considered that evidence derived from clinical trials and biomarkers supports clinical meaningfulness of an intervention, and when combined with a single clinical trial outcome, nearly all regarded the clinical trial design or biomarker evidence as supportive of disease modification. A minority considered biomarker evidence by itself as indicative of disease modification in prevention trials. Levels of evidence (A,B,C) were constructed based on these observations. The survey indicates the view of knowledgeable stakeholders regarding evidence derived from clinical trial design and biomarkers in support of disease modification. Results of this survey can assist in designing clinical trials of DMTs.

Impact of centrality on cooperative processes

Reia, Sandro M.; Herrmann, Sebastian; Fontanari, José F.

2017-02-01

The solution of today's complex problems requires the grouping of task forces whose members are usually connected remotely over long physical distances and different time zones. Hence, understanding the effects of imposed communication patterns (i.e., who can communicate with whom) on group performance is important. Here we use an agent-based model to explore the influence of the betweenness centrality of the nodes on the time the group requires to find the global maxima of NK-fitness landscapes. The agents cooperate by broadcasting messages, informing on their fitness to their neighbors, and use this information to copy the more successful agents in their neighborhood. We find that for easy tasks (smooth landscapes), the topology of the communication network has no effect on the performance of the group, and that the more central nodes are the most likely to find the global maximum first. For difficult tasks (rugged landscapes), however, we find a positive correlation between the variance of the betweenness among the network nodes and the group performance. For these tasks, the performances of individual nodes are strongly influenced by the agents' dispositions to cooperate and by the particular realizations of the rugged landscapes.

Decision rules and group rationality: cognitive gain or standstill?

PubMed

Curşeu, Petru Lucian; Jansen, Rob J G; Chappin, Maryse M H

2013-01-01

Recent research in group cognition points towards the existence of collective cognitive competencies that transcend individual group members' cognitive competencies. Since rationality is a key cognitive competence for group decision making, and group cognition emerges from the coordination of individual cognition during social interactions, this study tests the extent to which collaborative and consultative decision rules impact the emergence of group rationality. Using a set of decision tasks adapted from the heuristics and biases literature, we evaluate rationality as the extent to which individual choices are aligned with a normative ideal. We further operationalize group rationality as cognitive synergy (the extent to which collective rationality exceeds average or best individual rationality in the group), and we test the effect of collaborative and consultative decision rules in a sample of 176 groups. Our results show that the collaborative decision rule has superior synergic effects as compared to the consultative decision rule. The ninety one groups working in a collaborative fashion made more rational choices (above and beyond the average rationality of their members) than the eighty five groups working in a consultative fashion. Moreover, the groups using a collaborative decision rule were closer to the rationality of their best member than groups using consultative decision rules. Nevertheless, on average groups did not outperformed their best member. Therefore, our results reveal how decision rules prescribing interpersonal interactions impact on the emergence of collective cognitive competencies. They also open potential venues for further research on the emergence of collective rationality in human decision-making groups.

[What is the situation with human rights of the elderly? : UN Open-ended Working Group on Ageing - review and prospects].

2017-06-01

In November 2010 the United Nations General Assembly set up a working group to strengthen the protection of human rights for older persons (UN Open-ended Working Group on Ageing) with the United Nations Resolution A/C.3/65/L.8/Rev.1. In December 2016 the members of the working group met for the seventh time and discussed how they can approach the fulfillment of the mandate. In addition to better implementation, the strengthening of rights can consist of closing existing gaps or further differentiation of the rights in order to give the member states better guidance on how to implement them. To improve the human rights of older persons a task of the members of the working group would be to examine the existing rights and, where possible, adjust them to the real needs of the group. One of the major challenges facing the working group is already apparent: who belongs to the group of older persons and how could the group be described? This article deals with the presentation of the international process, new developments at the regional level and the attitudes of the member states and the civil society. A further aim is to present the possibilities and effects of a comprehensive legally binding instrument.

This paper presents the activities and publications of Organisation for Economic Co-operation and Developments (OECD's) Working Group on Harmonisation of Regulatory Oversight in Biotechnology and the Task Force for the Safety of Novel Foods and Feeds. The main outputs of the work are the Series of "consensus documents" of the respective groups. These documents compile information which is intended to be used by those involved in the business of risk/safety assessment. These documents are one means of ensuring the transportability of data amongst authorities. An increasing trend in both the Working Group and Task Force is to consider crop species which are relevant to tropical regions and therefore to countries that are not necessarily members of the OECD. For example, the Working Group has recently published a consensus document on bananas and plantains while the Task Force has published a document on cassava. This trend towards crops of greater interest in the tropics is likely to continue into the future.

Influence of mental practice on development of voluntary control of a novel motor acquisition task.

PubMed

Creelman, Jim

2003-08-01

The purpose of this investigation was to assess whether mental practice facilitates the development of voluntary control over the recruitment of the abductor hallucis muscle to produce isolated big toe abduction. A sample of convenience of 15 women and 20 men with a mean age of 28.8 yr. (SD=5.7) and healthy feet, who were unable voluntarily to abduct the big toe, were randomly assigned to one of three groups, a mental practice group, a physical practice group, and a group who performed a control movement during practice. Each subject received neuromuscular electrical stimulation to introduce the desired movement prior to each of five practice bouts over a single session lasting 2 hr. Big toe abduction active range of motion and surface electromyographic (EMG) output of the abductor hallucis and extensor digitorum brevis muscles were measured prior to the first practice bout and following each practice bout, yielding seven acquisition trials. Acquisition is defined as an improvement in both active range of motion and in the difference between the integrated EMG of the abductor hallucis and extensor digitorum brevis muscles during successive acquisition trials. Seven members of both the mental and physical practice groups and one member of the control group met the acquisition criteria. Chi-square analysis indicated the group difference was statistically significant, suggesting mental practice was effective for this task.

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 responsibilities may improve team workload distribution.

The basis of shooter biases: beyond cultural stereotypes.

PubMed

Miller, Saul L; Zielaskowski, Kate; Plant, E Ashby

2012-10-01

White police officers and undergraduate students mistakenly shoot unarmed Black suspects more than White suspects on computerized shoot/don't shoot tasks. This bias is typically attributed to cultural stereotypes of Black men. Yet, previous research has not examined whether such biases emerge even in the absence of cultural stereotypes. The current research investigates whether individual differences in chronic beliefs about interpersonal threat interact with target group membership to elicit shooter biases, even when group membership is unrelated to race or cultural stereotypes about danger. Across two studies, participants with strong beliefs about interpersonal threats were more likely to mistakenly shoot outgroup members than ingroup members; this was observed for unfamiliar, arbitrarily formed groups using a minimal group paradigm (Study 1) and racial groups not culturally stereotyped as dangerous (Asians; Study 2). Implications for the roles of both group membership and cultural stereotypes in shaping decisions to shoot are discussed.

The effects of reward and punishment are different, and there are individual differences in sensitivity to reward and punishment. The purpose of this study was to investigate the effects of reward and punishment on task performance, mood, and autonomic nervous function, along with the interaction with personality. Twenty-one healthy female subjects volunteered for the experiment. The task performance was evaluated by required time and total errors while performing a Wisconsin Card Sorting Test. We assessed their personalities using the Minnesota Multiphasic Personality Inventory (MMPI) questionnaire, and mood states by a profile of mood states. Autonomic nervous function was estimated by a spectral analysis of heart rate variability, baroreflex sensitivity, and blood pressure. Repeated measures analysis of variance (ANOVA) revealed significant interaction of condition x time course on mood and autonomic nervous activity, which would indicate a less stressed state under the rewarding condition, but revealed no significant interaction of condition x time course on the task performance. The interactions with personality were further analyzed by repeated measures ANOVA applying the clinical scales of MMPI as independent variables, and significant interactions of condition x time course x Pt (psychasthenia) on task performance, mood, and blood pressure, were revealed. That is, the high Pt group, whose members tend to be sensitive and prone to worry, showed gradual improvement of task performance under the punishing situation with slight increase in systolic blood pressure, while showed no improvement under the rewarding situation with fatigue sense attenuation. In contrast, the low Pt group, whose members tend to be adaptive and self-confident, showed gradual improvement under the rewarding situation. Therefore, we should carefully choose the strategy of reward or punishment, considering the interaction with personality as well as the context in which it is given.

Social networks predict selective observation and information spread in ravens

Animals are predicted to selectively observe and learn from the conspecifics with whom they share social connections. Yet, hardly anything is known about the role of different connections in observation and learning. To address the relationships between social connections, observation and learning, we investigated transmission of information in two raven (Corvus corax) groups. First, we quantified social connections in each group by constructing networks on affiliative interactions, aggressive interactions and proximity. We then seeded novel information by training one group member on a novel task and allowing others to observe. In each group, an observation network based on who observed whose task-solving behaviour was strongly correlated with networks based on affiliative interactions and proximity. Ravens with high social centrality (strength, eigenvector, information centrality) in the affiliative interaction network were also central in the observation network, possibly as a result of solving the task sooner. Network-based diffusion analysis revealed that the order that ravens first solved the task was best predicted by connections in the affiliative interaction network in a group of subadult ravens, and by social rank and kinship (which influenced affiliative interactions) in a group of juvenile ravens. Our results demonstrate that not all social connections are equally effective at predicting the patterns of selective observation and information transmission. PMID:27493780

To identify the specific needs, preferences and expectations of the stakeholders impacted by returning neuroimaging incidental findings to research participants. Six key stakeholder groups were identified to participate in focus group discussions at our active neuroimaging research facility: Participants, Parents of child participants, Investigators, Institutional Review Board (IRB) Members, Physicians and Community Members. A total of 151 subjects attended these discussions. Transcripts were analysed using principles of Grounded Theory and group consensus coding. A series of similar and divergent themes were identified across our subject groups. Similarities included beliefs that it is ethical for researchers to disclose incidental findings as it grants certain health and emotional benefits to participants. All stakeholders also recognised the potential psychological and financial risks to disclosure. Divergent perspectives elucidated consistent differences between our 'Participant' subjects (Participants, Parents, Community Members) and our 'Professional' subjects (IRB Members, Investigators and Physicians). Key differences included (1) what results should be reported, (2) participants' autonomous right to research information and (3) the perception of the risk-benefit ratio in managing results. Understanding the perceived impact on all stakeholders involved in the process of disclosing incidental findings is necessary to determine appropriate research management policy. Our data further demonstrate the challenge of this task as different stakeholders evaluate the balance between risk and benefit related to their unique positions in this process. These findings offer some of the first qualitative insight into the expectations of the diverse stakeholders affected by incidental finding disclosure. Published by the BMJ Publishing Group Limited.

Learning through "huddles" for health care leaders: why do some work teams learn as a result of huddles and others do not?

PubMed

Little, Johanna

2014-01-01

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.

A subset of the AGARD-STRES battery including memory search, unstable tracking, and a combination of both tasks (dual-task), was applied repeatedly to the four chamber crew members before, during, and after the 60-day isolation period of EXEMSI. Five ground control group members served as a control group. A subjective state questionnaire was also included. The results were subjected to a quantitative single-subject analysis. Electroencephalograms (EEG) were recorded to permit correlation of changes in task performance with changes in the physiological state. Evaluation of the EEG focused on spectral parameters of spontaneous EEG waves. No physiological data were collected from the control group. Significant decrements in tracking ability were observed in the chamber crew. The time course of these effects followed a triphasic pattern with initial deterioration, intermediate recovery to pre-isolation baseline scores after the first half of the isolation period, and a second deterioration towards the end. None of the control group subjects displayed such an effect. Memory search (speed and accuracy) was only occasionally impaired during isolation, but the control group displayed a similar pattern of changes. It is suggested that a state of decreased alertness causes tracking deterioration, which leads to a reduced efficiency of sustained cue utilization. The assumption of low alertness was further substantiated by higher fatigue ratings by the chamber crew compared to those of the control group. Analysis of the continuous EEG recordings revealed that only two subjects produced reliable alpha wave activity (8-12 Hz) over Pz and, to a much smaller extent, Fz-theta wave activity (5-7 Hz) during task performance. In both subjects Pz-alpha power decreased consistently under task conditions involving single-task and dual-task tracking. Fz-theta activity was increased more by single-task and dual-task memory search than by single-task tracking. The alpha attenuation appears to be associated with an increasing demand on perceptual cue utilization required by the tracking performance. In one subject marked attenuation of alpha power occurred during the first half of the confinement period, where he also scored the highest fatigue ratings. A striking increase in fronto-central theta activity was observed in the same subject after six weeks of isolation. The change was associated with an efficient rather than a degraded task performance, and a high rating of the item "concentrated" and a low rating of the item "fatigued." This finding supports the hypothesis that the activation state associated with increased fronto-central theta activity accompanies efficient performance of demanding mental tasks. The usefulness of standardized laboratory tasks as monitoring instruments is demonstrated by the direct comparability with results of studies obtained from other relevant research applications using the same tasks. The feasibility of a self-administered integrated psychophysiological assessment of the individual state was illustrated by the nearly complete collection of data. The large number of individual data collected over the entire period permitted application of quantitative single-subject analysis, allowing reliable determination of changes in the individual state in the course of time. It thus appears that this assessment technique can be adapted for in-flight monitoring of astronauts during prolonged spaceflights. Parallel EEG recording can provide relevant supplementary information for diagnosing the individual activation state associated with task performance. The existence of large individual differences in the generation of task-sensitive EEG rhythms forms an important issue for further studies.

The relationship between three-dimensional imaging and group decision making: an exploratory study.

This paper describes an empirical investigation of the effect of three dimensional (3-D) imaging on group performance in a tactical planning task. The objective of the study is to examine the role that stereoscopic imaging can play in supporting face-to-face group problem solving and decision making-in particular, the alternative generation and evaluation processes in teams. It was hypothesized that with the stereoscopic display, group members would better visualize the information concerning the task environment, producing open communication and information exchanges. The experimental setting was a tactical command and control task, and the quality of the decisions and nature of the group decision process were investigated with three treatments: 1) noncomputerized, i.e., topographic maps with depth cues; 2) two-dimensional (2-D) imaging; and 3) stereoscopic imaging. The results were mixed on group performance. However, those groups with the stereoscopic displays generated more alternatives and spent less time on evaluation. In addition, the stereoscopic decision aid did not interfere with the group problem solving and decision-making processes. The paper concludes with a discussion of potential benefits, and the need to resolve demonstrated weaknesses of the technology.

Cooperative context is a determinant of the social influence on outcome evaluation: An electrophysiological study.

PubMed

Kimura, Kenta; Katayama, Jun'ichi

2016-02-01

The present study examined whether or not a cooperative context is a determinant of the social influence on the evaluation of two action outcomes: a monetary outcome and a conflict of opinion with other group members. In the present study, three-person groups were randomly assigned to be either a cooperative or individual group and asked to perform a gambling task. The monetary outcomes in the cooperative group were interrelated among group members, whereas those in the individual group did not influence each other. The present results showed that monetary outcomes elicited feedback-related negativity (FRN) and a conflict of opinion with other group members elicited FRN-like negativity, which reflect an evaluation of the motivational significance of action outcomes. The FRN elicited by monetary outcomes was reduced when participants shared decisions with other group members only in the cooperative group, indicating that the cooperative context reduced the motivational significance of monetary outcomes through the diffusion of responsibility. The FRN-like negativity elicited by a conflict of opinion showed a different pattern between the cooperative and individual groups, indicating that the cooperative context can influence the evaluation of a conflict of opinion, possibly via the modulation of group cohesiveness or conflict processing. The present results suggest that a cooperative context, rather than the social setting, is a determinant of the social influence on outcome evaluation. Copyright © 2015 Elsevier B.V.

Audience Design through Social Interaction during Group Discussion

Rogers, Shane L.; Fay, Nicolas; Maybery, Murray

2013-01-01

This paper contrasts two accounts of audience design during multiparty communication: audience design as a strategic individual-level message adjustment or as a non-strategic interaction-level message adjustment. Using a non-interactive communication task, Experiment 1 showed that people distinguish between messages designed for oneself and messages designed for another person; consistent with strategic message design, messages designed for another person/s were longer (number of words) than those designed for oneself. However, audience size did not affect message length (messages designed for different sized audiences were similar in length). Using an interactive communication task Experiment 2 showed that as group size increased so too did communicative effort (number of words exchanged between interlocutors). Consistent with a non-strategic account, as group members were added more social interaction was necessary to coordinate the group's collective situation model. Experiment 3 validates and extends the production measures used in Experiment 1 and 2 using a comprehension task. Taken together, our results indicate that audience design arises as a non-strategic outcome of social interaction during group discussion. PMID:23437343

A major goal of recent research in aging has been to examine cognitive plasticity in older adults and its capacity to counteract cognitive decline. The aim of the present study was to investigate whether older adults could benefit from brain training with video games in a cross-modal oddball task designed to assess distraction and alertness. Twenty-seven healthy older adults participated in the study (15 in the experimental group, 12 in the control group. The experimental group received 20 1-hr video game training sessions using a commercially available brain-training package (Lumosity) involving problem solving, mental calculation, working memory and attention tasks. The control group did not practice this package and, instead, attended meetings with the other members of the study several times along the course of the study. Both groups were evaluated before and after the intervention using a cross-modal oddball task measuring alertness and distraction. The results showed a significant reduction of distraction and an increase of alertness in the experimental group and no variation in the control group. These results suggest neurocognitive plasticity in the old human brain as training enhanced cognitive performance on attentional functions. ClinicalTrials.gov NCT02007616.

Facing a projected $1.4M deficit on a $35M operating budget for fiscal year 2011/2012, members of the Dalhousie University Faculty of Medicine developed and implemented an explicit, transparent, criteria-based priority setting process for resource reallocation. A task group that included representatives from across the Faculty of Medicine used a program budgeting and marginal analysis (PBMA) framework, which provided an alternative to the typical public-sector approaches to addressing a budget deficit of across-the-board spending cuts and political negotiation. Key steps to the PBMA process included training staff members and department heads on priority setting and resource reallocation, establishing process guidelines to meet immediate and longer-term fiscal needs, developing a reporting structure and forming key working groups, creating assessment criteria to guide resource reallocation decisions, assessing disinvestment proposals from all departments, and providing proposal implementation recommendations to the dean. All departments were required to submit proposals for consideration. The task group approved 27 service reduction proposals and 28 efficiency gains proposals, totaling approximately $2.7M in savings across two years. During this process, the task group faced a number of challenges, including a tight timeline for development and implementation (January to April 2011), a culture that historically supported decentralized planning, at times competing interests (e.g., research versus teaching objectives), and reductions in overall health care and postsecondary education government funding. Overall, faculty and staff preferred the PBMA approach to previous practices. Other institutions should use this example to set priorities in times of fiscal constraints.

Effective Collaboration for Scaling Up Health Technologies: A Case Study of the Chlorhexidine for Umbilical Cord Care Experience

2018-01-01

The global health field is replete with examples of cross-organizational collaborative partnerships, such as networks, alliances, coalitions, task forces, and working groups, often established to tackle a shared global health concern, condition, or threat affecting low-income countries or communities. The purpose of this article is to review factors influencing the effectiveness of a multi-agency global health collaborative effort using the Chlorhexidine Working Group (CWG) as our case study. The CWG was established to accelerate the introduction and global scale-up of chlorhexidine for umbilical cord care to reduce infection-related neonatal morbidity and mortality in low-income countries. Questions included: how current and past CWG members characterized the effectiveness, productivity, collaboration, and leadership of the CWG; what factors facilitated or hindered group function; institutional or individual reasons for participating and length of participation in the CWG; and lessons that might be relevant for future global collaborative partnerships. Data were collected through in-depth, semistructured individual interviews with 19 group members and a review of key guiding documents. Six domains of internal coalition functioning (leadership, interpersonal relationships, task focus, participant benefits and costs, sustainability planning, and community support) were used to frame and describe the functioning of the CWG. Collaboration effectiveness was found to depend on: (1) leadership that maintained a careful balance between discipline and flexibility, (2) a strong secretariat structure that supported the evolution of trust and transparent communication in interpersonal relationships, (3) shared goals that allowed for task focus, (4) diverse membership and active involvement from country-level participants, which created a positive benefit-cost ratio for participants, (5) sufficient resources to support the partnership and build sustainable capacity for members to accelerate the transfer of knowledge, and (6) support from the global health community across multiple organizations. Successful introduction and scale-up of new health interventions require effective collaboration across multiple organizations and disciplines, at both global and country levels. The participatory collaborative partnership approach utilized by the Chlorhexidine Working Group offers an instructive learning case. PMID:29602871

The aim was to describe the strengths and weaknesses, from team member perspectives, of working with the Global Trigger Tool (GTT) method of retrospective record review to identify adverse events causing patient harm. A qualitative, descriptive approach with focus group interviews using content analysis. 5 Swedish hospitals in 2011. 5 GTT teams, with 5 physicians and 11 registered nurses. 5 focus group interviews were carried out with the five teams. Interviews were taped and transcribed verbatim. 8 categories emerged relating to the strengths and weaknesses of the GTT method. The categories found were: Usefulness of the GTT, Application of the GTT, Triggers, Preventability of harm, Team composition, Team tasks, Team members' knowledge development and Documentation. Gradually, changes in the methodology were made by the teams, for example, the teams reported how the registered nurses divided up the charts into two sets, each being read respectively. The teams described the method as important and well functioning. Not only the most important, but also the most difficult, was the task of bringing the results back to the clinic. The teams found it easier to discuss findings at their own clinics. The GTT method functions well for identifying adverse events and is strengthened by its adaptability to different specialties. However, small, gradual methodological changes together with continuingly developed expertise and adaption to looking at harm from a patient's perspective may contribute to large differences in assessment over time.

This report provides the basis for discussion and subsequent articulation of a national plan for the Amphibian Research and Monitoring Initiative (ARMI). The authors were members of a task force formed from within the U.S. Geological Survey (USGS) that included scientists with expertise in biology, cartography, hydrology, and statistics. The assignment of the task force was to extend work begun by the National Amphibian Leadership Group. This group, composed of senior USGS scientists, managers, and external authorities, met in Gainesville, Florida, in February 20001. The product of this meeting was a document outlining the framework for a national program to monitor amphibian populations and to conduct research into the causes of declines.

There are currently no international safety standards and guidelines to assist designers, operators and authorities in the suborbital domain. There is a launch licensing regime in the United States (US) to assist the forerunners of the suborbital domain however this does not provide a safety approval for the vehicle against set standards or does not have an acceptable level of safety to achieve in terms of design or operation. In Europe a certification framework may be implemented however this (or any regulatory framework) is not in place as yet. This paper summarises the 5 tasks thus far completed by the International Association for the Advancement of Space Safety (IAASS) Suborbital Safety Technical Committee (SS TC) in terms of deriving standards and guidelines for the suborbital domain. The SS TC comprises members from the suborbital industry (US and European vehicle designers), safety experts, legal experts, medical/training experts, prospective spaceport operators and members from the US and European authorities (though these members cannot directly steer the standards and guidelines - they can merely review them for interest and comment on non-policy aspects). The SS TC has been divided into three working groups (WG): Regulatory WG, Technical WG and Operations WG. The 5 tasks that are summarised in this paper include: Regulatory WG - (Task 1) Clarify and promote regulatory framework for suborbital flights (including discussions on Space Law 'v' Air Law for suborbital domain); Technical WG - (Task 1) Defining & Alignment (globally) of Safety Criteria for Suborbital domain using industry best practices, (Task 2) Software/complex hardware certification for suborbital flights; Operations WG - (Task 1) Flight Crew and Spaceflight Participant Medical and Training Standards & Guidelines for suborbital flight, (Task 2) Spaceport Safety Management System. This paper also details the next set of standards and guidelines that will be derived by the SS TC. The paper concludes that these and future IAASS suborbital safety standards and guidelines are needed now and should beconsidered by the industry players before the first commercial flights expected late 2013/early 2014.

Patient safety depends on effective teamwork. The similarity of team members' mental models - or their shared understanding-regarding clinical tasks is likely to influence the effectiveness of teamwork. Mental models have not been measured in the complex, high-acuity environment of the operating room (OR), where professionals of different backgrounds must work together to achieve the best surgical outcome for each patient. Therefore, we aimed to explore the similarity of mental models of task sequence and of responsibility for task within multidisciplinary OR teams. We developed a computer-based card sorting tool (Momento) to capture the information on mental models in 20 six-person surgical teams, each comprised of three subteams (anaesthesia, surgery, and nursing) for two simulated laparotomies. Team members sorted 20 cards depicting key tasks according to when in the procedure each task should be performed, and which subteam was primarily responsible for each task. Within each OR team and subteam, we conducted pairwise comparisons of scores to arrive at mean similarity scores for each task. Mean similarity score for task sequence was 87 % (range 57-97 %). Mean score for responsibility for task was 70 % (range = 38-100 %), but for half of the tasks was only 51 % (range = 38-69 %). Participants believed their own subteam was primarily responsible for approximately half the tasks in each procedure. We found differences in the mental models of some OR team members about responsibility for and order of certain tasks in an emergency laparotomy. Momento is a tool that could help elucidate and better align the mental models of OR team members about surgical procedures and thereby improve teamwork and outcomes for patients.

Implications for the Self Determine Benevolence and Self-Protection in Intergroup Relations

People often favor groups they belong to over those beyond the in-group boundary. Yet, in-group favoritism does not always occur, and people will sometimes favor an out-group over the in-group. We delineate theoretically when in-group favoritism (i.e., self-protection) and out-group favoritism (i.e., benevolence) should occur. In two experiments, groups’ relative status and competence stereotypes were manipulated; groups’ outcomes were non-contingent in Experiment 1 and contingent in Experiment 2. When allocating reward, members of a low status group were self-protective, favoring the in-group over the out-group under both non-contingent and contingent outcomes. Those with high status benevolently favored the out-group when outcomes were non-contingent, but were self-protective with contingent outcomes. People were willing to engage in social activities with an out-group member regardless of competence. However, when task collaboration had implications for the self, those with low status preferred competent over less competent out-group members. Traits of high status targets were differentiated by those with low status in both experiments, whereas those with high status differentiated low status members’ traits only when outcomes were contingent. A general principle fits the data: the implications of intergroup responses for the self determine benevolence and self-protection.

Previous functional neuroimaging studies demonstrated that different neural networks underlie different types of cognitive processing by engaging participants in particular tasks, such as verbal or spatial working memory (WM) tasks. However, we report here that even when a working memory task is defined as verbal or spatial, different types of memory strategies may be employed to complete it, with concomitant variations in brain activity. We developed a questionnaire to characterize the type of strategy used by individual members in a group of 28 young healthy participants (18–25 years) during a spatial WM task. A cluster analysis was performed to differentiate groups. We acquired functional magnetoencephalography (MEG) and structural diffusion tensor imaging (DTI) measures to characterize the brain networks associated with the use of different strategies. We found two types of strategies were utilized during the spatial WM task, a visuospatial and a verbal strategy, and brain regions and timecourses of activation differed between participants who used each. Task performance also varied by type of strategy used, with verbal strategies showing an advantage. In addition, performance on neuropsychological tests (indices from WAIS-IV, REY-D Complex Figure) correlated significantly with fractional anisotropy (FA) measures for the visuospatial strategy group in white matter tracts implicated in other WM/attention studies. We conclude that differences in memory strategy can have a pronounced effect on the locations and timing of brain activation, and that these differences need further investigation as a possible confounding factor for studies using group averaging as a means for summarizing results.

Counselling and communication in hospital dentistry.

PubMed

Nordenram, G; Wiklund, K

2000-01-01

Many of the people who are members of hospital dental teams are highly motivated, caring individuals. Unfortunately, though, they are not given the kind of training or support that is necessary to enable them to perform their tasks most effectively. This study was initiated at a hospital dental clinic where burdensome cutbacks and reorganization had been keenly felt by the personnel. A counselling group was formed under the leadership of a professional counsellor, and in the course of the year there were seven meetings, each of which lasted 1.5-2 hours. The open way in which counselling was designed presented opportunities for the six group members to influence the topics of each meeting, something all of them preferred to more structured sessions. Different stress factors in the environment were discussed. The group members concluded that the counselling programme had increased their self-esteem and facilitated effective communication between the group and patients by giving them all the opportunity to discuss barriers and confusing clinical situations. Counselling had also facilitated interpersonal relationships between the team members by revealing hierarchical difficulties. Apart from the clear humanitarian need for counselling there is a good economic argument. Effective staff support is not a luxury, nor is it a waste of time. Adequate time for counselling must be provided, simply.

The essential tension between leadership and power: when leaders sacrifice group goals for the sake of self-interest.

PubMed

Maner, Jon K; Mead, Nicole L

2010-09-01

Throughout human history, leaders have been responsible for helping groups attain important goals. Ideally, leaders use their power to steer groups toward desired outcomes. However, leaders can also use their power in the service of self-interest rather than effective leadership. Five experiments identified factors within both the person and the social context that determine whether leaders wield their power to promote group goals versus self-interest. In most cases, leaders behaved in a manner consistent with group goals. However, when their power was tenuous due to instability within the hierarchy, leaders high (but not low) in dominance motivation prioritized their own power over group goals: They withheld valuable information from the group, excluded a highly skilled group member, and prevented a proficient group member from having any influence over a group task. These self-interested actions were eliminated when the group was competing against a rival outgroup. Findings provide important insight into factors that influence the way leaders navigate the essential tension between leadership and power.

[Effects of group entitativity on the judgment of collective intentionality and responsibility].

PubMed

Hioki, Koichi; Karasawa, Minoru

2010-04-01

Two studies investigated whether observers perceive collective intention and responsibility of a task group when a group member (i.e., a member of a company's board) committed a corporate crime. In Study 1, undergraduate students read a scenario describing a criminal case, in which the degree to which the group (i.e., the company's board) was likely to be perceived as a coherent acting agent (i.e., "entitativity") was manipulated. The results revealed that the perception of collective intentionality led to perceived responsibility of the group, and then to less favorable attitudes toward the company. However, there were no effects of entitativity on perceived intentionality and responsibility. With a refined experimental design, Study 2 showed that high group entitativity induced a high level of perceived intentionality and responsibility, particularly when the crime was directly relevant to the mission as a company (i.e., food manufacturing of a food company). Implications of these findings for other research areas such as business and law are discussed.

Performance and process in collective and individual memory: the role of social decision schemes and memory bias in collective memory.

Van Swol, Lyn M

2008-04-01

To assess performance and processes in collective and individual memory, participants watched two job candidates on video. Beforehand, half the participants were told they would be tested on their memory of the interviews, and the other half were asked to make a decision to hire one of the candidates. Afterwards, participants completed a recognition memory task in either a group or individual condition. Groups had better recognition memory than individuals. Individuals made more false positives than false negatives and groups exaggerated this. Post-hoc analysis found that groups only exaggerated the tendency towards false positives on items that reflected negatively on the job candidate. There was no significant difference between instruction conditions. When reaching consensus on the recognition task, groups tended to choose the correct answer if at least two members had the correct answer. This method of consensus is discussed as a factor in groups' superior memory performance.

The Interlibrary Loan, Document Delivery, and Union List Task Force of the Health Sciences Libraries Consortium (HSLC)--with nineteen libraries located in Philadelphia, Pittsburgh, and Hershey, Pennsylvania, and Delaware--accepted the charge of evaluating and recommending for purchase telefacsimile hardware to further interlibrary loan among HSLC members. To allow a thorough and scientific evaluation of group 3 level telefacsimile equipment, the task force identified ninety-six hardware features, which were grouped into nine broad criteria. These features formed the basis of a weighted analysis that identified three final candidates, with one model recommended to the HSLC board. This article details each of the criteria and discusses features in terms of library applications. The evaluation grid developed in the weighted analysis process should aid librarians charged with the selection of level 3 telefacsimile equipment. PMID:2328361

Summary Background Inpatient teams commonly track their tasks using paper checklists that are not shared between team members. Team members frequently communicate redundantly in order to prevent errors. Methods We created a mobile, collaborative, real-time task list application on the iOS platform. The application listed tasks for each patient, allowed users to check them off as completed, and transmitted that information to all other team members. In this report, we qualitatively describe our experience designing and piloting the application with an inpatient pediatric ward team at an academic pediatric hospital. Results We successfully created the tasklist application, however team members showed limited usage. Conclusion Physicians described that they preferred the immediacy and familiarity of paper, and did not experience an efficiency benefit when using the electronic tasklist. PMID:26767063

A major goal of recent research in aging has been to examine cognitive plasticity in older adults and its capacity to counteract cognitive decline. The aim of the present study was to investigate whether older adults could benefit from brain training with video games in a cross-modal oddball task designed to assess distraction and alertness. Twenty-seven healthy older adults participated in the study (15 in the experimental group, 12 in the control group. The experimental group received 20 1-hr video game training sessions using a commercially available brain-training package (Lumosity) involving problem solving, mental calculation, working memory and attention tasks. The control group did not practice this package and, instead, attended meetings with the other members of the study several times along the course of the study. Both groups were evaluated before and after the intervention using a cross-modal oddball task measuring alertness and distraction. The results showed a significant reduction of distraction and an increase of alertness in the experimental group and no variation in the control group. These results suggest neurocognitive plasticity in the old human brain as training enhanced cognitive performance on attentional functions.

The purpose of this report is to describe caregiving by teens for family members with Huntington disease (HD). Thirty-two teens in HD families in the United States and Canada participated in focus groups from 2002 to 2005 in a study to identify concerns and strategies to manage concerns. An unexpected finding was 24 (77%) described caregiving activities. Descriptive analysis of caregiving statements identified themes of Tasks and Responsibilities, Subjective Burden, Caregiving in Context of Personal Risk for HD, and Decisional Responsibility. Teens took an active part in nearly all aspects of care with the exception of contacting health care providers and attending doctors’ appointments. Some described emotional distress, and many provided care knowing they had the potential to develop HD. Teens recognized the need for decisions but lacked the authority to make these decisions. Findings may be relevant for other teens who strive to meet caregiver and student roles and developmental tasks. PMID:19465560

Breaking the students into small, collaborative learning groups to solve a meaningful task together is one of the most successful and fully evaluated teaching techniques implemented over the last century. Although there are many ways to accomplish small group learning, a long-standing and consistently successful collaborative class activity is to use the case study teaching strategy. The use of case studies is common in medical schools and law schools, but not so common in the teaching of astronomy. Case studies create meaningful conversations among students and with the professor by focusing on life-like dilemmas to be solved. Case study tasks ask audience members to synthesize several ideas or evaluate scenarios that have not been explicitly presented to them in the lecture or in available readings.

A new Child and Adolescent Psychiatry in Medical Education (CAPME) Task Force, sponsored by the Association for Directors of Medical Student Education in Psychiatry (ADMSEP), has created an inter-organizational partnership between child and adolescent psychiatry (CAP) educators and medical student educators in psychiatry. This paper outlines the task force design and strategic plan to address the long-standing dearth of CAP training for medical students. The CAPME ADMSEP Task Force, formed in 2010, identified common challenges to teaching CAP among ADMSEP's CAPME Task Force members, utilizing focus-group discussions and a needs-assessment survey. The Task Force was organized into five major sections, with inter-organizational action plans to address identified areas of need, such as portable modules and development of benchmark CAP competencies. The authors predict that all new physicians, regardless of specialty, will be better trained in CAP. Increased exposure may also improve recruitment into this underserved area.

Decision Rules and Group Rationality: Cognitive Gain or Standstill?

PubMed Central

Curşeu, Petru Lucian; Jansen, Rob J. G.; Chappin, Maryse M. H.

2013-01-01

Recent research in group cognition points towards the existence of collective cognitive competencies that transcend individual group members’ cognitive competencies. Since rationality is a key cognitive competence for group decision making, and group cognition emerges from the coordination of individual cognition during social interactions, this study tests the extent to which collaborative and consultative decision rules impact the emergence of group rationality. Using a set of decision tasks adapted from the heuristics and biases literature, we evaluate rationality as the extent to which individual choices are aligned with a normative ideal. We further operationalize group rationality as cognitive synergy (the extent to which collective rationality exceeds average or best individual rationality in the group), and we test the effect of collaborative and consultative decision rules in a sample of 176 groups. Our results show that the collaborative decision rule has superior synergic effects as compared to the consultative decision rule. The ninety one groups working in a collaborative fashion made more rational choices (above and beyond the average rationality of their members) than the eighty five groups working in a consultative fashion. Moreover, the groups using a collaborative decision rule were closer to the rationality of their best member than groups using consultative decision rules. Nevertheless, on average groups did not outperformed their best member. Therefore, our results reveal how decision rules prescribing interpersonal interactions impact on the emergence of collective cognitive competencies. They also open potential venues for further research on the emergence of collective rationality in human decision-making groups. PMID:23451050

Automatic stereotyping against people with schizophrenia, schizoaffective and affective disorders

2010-01-01

Similar to members of the public, people with mental illness may exhibit general negative automatic prejudice against their own group. However, it is unclear whether more specific negative stereotypes are automatically activated among diagnosed individuals and how such automatic stereotyping may be related to self-reported attitudes and emotional reactions. We therefore studied automatically activated reactions toward mental illness among 85 people with schizophrenia, schizoaffective or affective disorders as well as among 50 members of the general public, using a Lexical Decision Task to measure automatic stereotyping. Deliberately endorsed attitudes and emotional reactions were assessed by self-report. Independent of diagnosis, people with mental illness showed less negative automatic stereotyping than did members of the public. Among members of the public, stronger automatic stereotyping was associated with more self-reported shame about a potential mental illness and more anger toward stigmatized individuals. Reduced automatic stereotyping in the diagnosed group suggests that people with mental illness might not entirely internalize societal stigma. Among members of the public, automatic stereotyping predicted negative emotional reactions to people with mental illness. Initiatives to reduce the impact of public stigma and internalized stigma should take automatic stereotyping and related emotional aspects of stigma into account. PMID:20843560

2000-01-01

The authors suggest that a charismatic leadership style has an impact on the maintenance of boundaries and standards of practice within a department of psychiatry. They also underline the need for all members of a self-regulated professional group to assume responsibility for the maintenance of standards within the group. An overview of leadership tasks and styles, with particular emphasis on the qualities of charismatic leadership, is provided, and the impacts of boundary violations committed by members of a psychiatric department or institute on the integrity of the professional group are also elaborated. The authors then develop several hypotheses regarding the phenomenon of emotional collusion that occurs in departments in which a charismatic leader becomes sexually involved with patients. The individual internal psychological mechanisms and companion group dynamics that may allow the leader to be supported at the cost of ethical standards, principles of practice, and the ultimate creativity and viability of the group are then discussed. The authors conclude that the maintenance of standards within a self-regulating professional group must be the shared responsibility of all members. The example of boundary violations by a charismatic leader is used to illustrate the need for open debate regarding fundamental principles required to maintain a healthy functioning of critical checks and balances within the psychiatric profession.

Community-based participatory research (CBPR) has great potential to address cancer disparities, particularly in racially and ethnically diverse and underserved neighborhoods. The objective of this study was to conduct a process evaluation of an innovative academic-community partnership, Queens Library HealthLink, which aimed to reduce cancer disparities through neighborhood groups (Cancer Action Councils) that convened in public libraries in Queens, New York. We used a mixed-methods approach to conduct 69 telephone survey interviews and 4 focus groups (15 participants) with Cancer Action Council members. We used 4 performance criteria to inform data collection: action or attention to sustainability, library support for the council, social cohesion and group leadership, and activity level. Focus group transcripts were independently coded and cross-checked for consensus until saturation was achieved. Members reported benefits and barriers to participation. Thirty-three original focus group transcript codes were organized into 8 main themes related to member experiences: 1) library as a needed resource, 2) library as a reputable and nondenominational institution, 3) value of library staff, 4) need for a HealthLink specialist, 5) generation of ideas and coordination of tasks, 6) participation challenges, 7) use of community connections, and 8) collaboration for sustainability. In response to the process evaluation, Cancer Action Council members and HealthLink staff incorporated member suggestions to improve council sustainability. The councils merged to increase intercouncil collaboration, and institutional changes were made in funding to sustain a HealthLink specialist beyond the grant period.

Gender influences as an impediment to knowledge sharing: when men and women fail to seek peer feedback.

Miller, Diane L; Karakowsky, Leonard

2005-03-01

Little research has considered how work team characteristics influence feedback-seeking behavior among team members. The authors' aim in this research was to identify central sources of influence on feedback-seeking behavior in a mixed-gender context. They placed men and women in work groups of varying gender composition. The participants then participated in a gender-biased (perceived as either male-oriented or female-oriented) negotiation exercise. Findings indicated that the gender of the participant, the team's gender composition, and the gender orientation of the task influenced feedback-seeking behavior among team members.

Silence is golden: effect of encouragement in motivating the weak link in an online exercise video game.

Irwin, Brandon C; Feltz, Deborah L; Kerr, Norbert L

2013-06-04

Despite the physical and mental health benefits, few adults meet US Department of Health and Human Services physical activity guidelines for exercise frequency, intensity, and duration. One strategy that may increase physical activity duration is exercising with an Internet partner (ie, someone who is virtually present, as in video chat). Internet partners help people overcome many barriers associated with face-to-face exercise groups (eg, time, coordinating schedules, social physique anxiety). Past research examining individual performance in groups suggests that an increase in effort occurs when performing a task conjunctively, ie, when a participant is (1) less capable than fellow group members, and (2) participants efforts are particularly indispensable for group success (ie, where the group's potential productivity is equal to the productivity of its least capable member). This boost in effort is more commonly known as the Köhler effect, named after the German psychologist who first observed the effect. While encouragement between group members is common practice in face-to-face group exercise, the effect of encouragement between partners exercising conjunctively across the Internet is unknown. To examine the impact of exercising alone, compared to exercising conjunctively with an Internet partner, both with and without encouragement, on exercise persistence (primary outcomes) and secondary psychosocial outcomes (self-efficacy, enjoyment, exercise intention). Participants were recruited online and face-to-face from the campus of Michigan State University. With the assistance of the experimenter, participants (n=115) played an exercise video game in a laboratory, performing a series of five abdominal plank exercises where they were asked to hold the plank for as long as possible (Time 1). They were then randomized to a condition (Individual, Partner-without-encouragement, or Partner-with-encouragement), where they performed the exercises again (Time 2). The impact of condition on the primary outcome measures and secondary outcome measures were evaluated using a 2 (Gender) x 3 (Condition) ANOVA on change scores (Time 2-Time 1). Those who exercised in online teams (n=80) exercised significantly longer (time=78.8s, P<.001) than those who worked individually (n=35). However, exercise duration was shorter when one's more capable partner gave verbal encouragement (n=55) than when s/he did not (n=25) (a mean difference of 31.14s). These increases in effort were not accompanied by altered task self-efficacy, enjoyment of the task, or intention to exercise in the future. Exercising conjunctively with an Internet partner can boost one's duration of exercise. However, encouragement from the stronger to the weaker member can mitigate these gains, especially if one perceives such comments being directed at someone other than themselves. To boost exercise duration, Internet-based physical activity interventions involving group interaction should make relative abilities of participants known and communication clear.

Oxytocin promotes group-serving dishonesty.

PubMed

Shalvi, Shaul; De Dreu, Carsten K W

2014-04-15

To protect and promote the well-being of others, humans may bend the truth and behave unethically. Here we link such tendencies to oxytocin, a neuropeptide known to promote affiliation and cooperation with others. Using a simple coin-toss prediction task in which participants could dishonestly report their performance levels to benefit their group's outcome, we tested the prediction that oxytocin increases group-serving dishonesty. A double-blind, placebo-controlled experiment allowing individuals to lie privately and anonymously to benefit themselves and fellow group members showed that healthy males (n = 60) receiving intranasal oxytocin, rather than placebo, lied more to benefit their group, and did so faster, yet did not necessarily do so because they expected reciprocal dishonesty from fellow group members. Treatment effects emerged when lying had financial consequences and money could be gained; when losses were at stake, individuals in placebo and oxytocin conditions lied to similar degrees. In a control condition (n = 60) in which dishonesty only benefited participants themselves, but not fellow group members, oxytocin did not influence lying. Together, these findings fit a functional perspective on morality revealing dishonesty to be plastic and rooted in evolved neurobiological circuitries, and align with work showing that oxytocin shifts the decision-maker's focus from self to group interests. These findings highlight the role of bonding and cooperation in shaping dishonesty, providing insight into when and why collaboration turns into corruption.

When Does Diversity Trump Ability (and Vice Versa) in Group Decision Making? A Simulation Study

Luan, Shenghua; Katsikopoulos, Konstantinos V.; Reimer, Torsten

2012-01-01

It is often unclear which factor plays a more critical role in determining a group's performance: the diversity among members of the group or their individual abilities. In this study, we addressed this “diversity vs. ability” issue in a decision-making task. We conducted three simulation studies in which we manipulated agents' individual ability (or accuracy, in the context of our investigation) and group diversity by varying (1) the heuristics agents used to search task-relevant information (i.e., cues); (2) the size of their groups; (3) how much they had learned about a good cue search order; and (4) the magnitude of errors in the information they searched. In each study, we found that a manipulation reducing agents' individual accuracy simultaneously increased their group's diversity, leading to a conflict between the two. These conflicts enabled us to identify certain conditions under which diversity trumps individual accuracy, and vice versa. Specifically, we found that individual accuracy is more important in task environments in which cues differ greatly in the quality of their information, and diversity matters more when such differences are relatively small. Changing the size of a group and the amount of learning by an agent had a limited impact on this general effect of task environment. Furthermore, we found that a group achieves its highest accuracy when there is an intermediate amount of errors in the cue information, regardless of the environment and the heuristic used, an effect that we believe has not been previously reported and warrants further investigation.

The mere presence of an outgroup member disrupts the brain's feedback-monitoring system.

Hobson, Nicholas M; Inzlicht, Michael

2016-11-01

Much of human learning happens in the social world. A person's social identity-the groups to which they belong, the people with whom they identify-is a powerful cue that can affect our goal-directed behaviors, often implicitly. In the present experiment, we explored the underlying neural mechanisms driving these processes, testing hypotheses derived from social identity theory. In a within-subjects design, participants underwent a minimal group manipulation where they were randomly assigned to an arbitrary ingroup. In two blocks of the experiment, participants were asked to complete a task for money while being observed by an ingroup member and outgroup member separately. Results revealed that being observed by an ingroup or outgroup member led to divergent patterns of neural activity associated with feedback monitoring, namely the feedback-related negativity (FRN). Receiving feedback in the presence of an ingroup member produced a typical FRN signal, but the FRN was dampened while receiving feedback in the presence of an outgroup member. Further, this differentiated neural pattern was exaggerated in people who reported greater intergroup bias. Together, the mere presence of a person can alter how the brain adaptively monitors feedback, impairing the reinforcement learning signal when the person observing is an outgroup member. © The Author (2016).

Reframing Balint: thoughts on family medicine departmental Balint groups.

Stein, Howard F

2003-04-01

This paper explores recurrent processes and themes in the 1,300 family medicine faculty, resident, intern, and community Balint groups the author has facilitated/led. The frequent group "deviation" from the central Balint task of understanding difficult physician-patient relationships is reframed as less "resistance" or "obstacle" to work, as it is an expression of unmet developmental needs and organizational realities. When group members are carefully attended to (by facilitator and one another), the group often becomes emotionally capable of addressing a "case " in the conventional Balint understanding of the work the group has assembled to do. The group dynamics of such "hybrid" Balint groups thus become comprehensible as other than error.

2008-01-01

This article explores the linkages between strategies for managing different types of conflict and group performance and satisfaction. Results from a qualitative study of 57 autonomous teams suggest that groups that improve or maintain top performance over time share 3 conflict resolution tendencies: (a) focusing on the content of interpersonal interactions rather than delivery style, (b) explicitly discussing reasons behind any decisions reached in accepting and distributing work assignments, and (c) assigning work to members who have the relevant task expertise rather than assigning by other common means such as volunteering, default, or convenience. The authors' results also suggest that teams that are successful over time are likely to be both proactive in anticipating the need for conflict resolution and pluralistic in developing conflict resolution strategies that apply to all group members. 2008 APA

We examine the DataONE (Data Observation Network for Earth) project, a transdisciplinary organization tasked with creating a cyberinfrastructure platform to ensure preservation of and access to environmental science and biological science data. Its objective was a difficult one to achieve, requiring innovative solutions. The DataONE project used a working group structure to organize its members. We use organizational discontinuity theory as our lens to understand the factors associated with success in such projects. Based on quantitative and qualitative data collected from DataONE members, we offer recommendations for the use of working groups in transdisciplinary synthesis. Recommendations include welcome diverse opinions and world views, establish shared communication practices, schedule periodic synchronous face-to-face meetings, and ensure the active participation of bridge builders or knowledge brokers such as librarians who know how to ask questions about disciplines not their own.

Gulf Coast Ecosystem Restoration Task Force---Gulf of Mexico Ecosystem Science Assessment and Needs

USGS Publications Warehouse

Walker, Shelby; Dausman, Alyssa M.; Lavoie, Dawn L.

2012-01-01

The Gulf Coast Ecosystem Restoration Task Force (GCERTF) was established by Executive Order 13554 as a result of recommendations from “America’s Gulf Coast: A Long-term Recovery Plan after the Deepwater Horizon Oil Spill” by Secretary of the Navy Ray Mabus (Mabus Report). The GCERTF consists of members from 11 Federal agencies and representatives from each State bordering the Gulf of Mexico. The GCERTF was charged to develop a holistic, long-term, science-based Regional Ecosystem Restoration Strategy for the Gulf of Mexico. Federal and State agencies staffed the GCERTF with experts in fields such as policy, budgeting, and science to help develop the Strategy. The Strategy was built on existing authorities and resources and represents enhanced collaboration and a recognition of the shared responsibility among Federal and State governments to restore the Gulf Coast ecosystem. In this time of severe fiscal constraints, Task Force member agencies and States are committed to establishing shared priorities and working together to achieve them.As part of this effort, three staffers, one National Oceanic and Atmospheric Administration (NOAA) scientist and two U.S. Geological Survey (USGS) scientists, created and led a Science Coordination Team (SCT) to guide scientific input into the development of the Gulf of Mexico Regional Ecosystem Restoration Strategy. The SCT leads from the GCERTF coordinated more than 70 scientists from the Federal and State Task Force member agencies to participate in development of a restoration-oriented science document focused on the entire Gulf of Mexico, from inland watersheds to the deep blue waters. The SCT leads and scientists were organized into six different working groups based on expanded goals from the Mabus Report: Coastal habitats are healthy and resilient.Living coastal and marine resources are healthy, diverse, and sustainable.Coastal communities are adaptive and resilient.Storm buffers are sustainable.Inland habitats and watersheds are managed to help support healthy and sustainable Gulf of Mexico ecosystems.Offshore environments are healthy and well managedEach working group was charged with defining their specific goal, describing the current conditions related to that goal (for example, the status of coastal habitats in the Gulf of Mexico), providing highlevel activities needed to further define and achieve the goal, with associated outcome-based performance indicators, and identifying the scientific gaps in understanding to accomplish the goal and implement the recommended activities. The overall scientific assessment reveals that the Gulf of Mexico ecosystem continues to suffer from extensive degradation, and action is necessary to develop a healthy, resilient, and sustainable Gulf of Mexico ecosystem. The six groups also were tasked with outlining the necessary monitoring, modeling, and research needs to aid in achieving the goals. Recognizing that (1) the scientific needs (monitoring, modeling, and research) overlap among many of the goals, and (2) an overarching scientific framework could be developed to implement the necessary science in support of the Strategy, a seventh group was created with several members from each of the original six working groups. This seventh group compiled all of the cross-cutting monitoring, modeling, and research needs previously identified by the individual groups. These scientific requirements are found in Chapter 5 of this document. The seventh group also has developed a Science Plan, outlined in Chapter 6. The Science Plan provides the basic science infrastructure to support the overall Gulf restoration program and Strategy. The Science Plan allows for the development of an iterative and flexible approach to adaptive management and decision-making related to restoration projects based on sound science that includes monitoring, modeling, and research. Taken in its entirety, this document helps to articulate the current state of the system and the critical science needs to support effective restoration of the Gulf of Mexico resources that have been trending towards decline for decades.

With the move towards globalized international commerce and trade, a call for harmonization of medical device regulatory requirements and practices has evolved. The purpose of the Global Harmonization Task Force (GHTF) is to encourage convergence of regulatory requirements and practices at a global level through consensus to achieve four principle goals: promote safety, quality and performance/effectiveness of medical devices; encourage technological innovation; foster international trade; and serve as a forum of information exchange - all in the interests of protecting and promoting public health. The GHTF is governed by a Steering Committee, and the principle development of the GHTF regulatory model has been, and continues to be, done through five working groups known as Study Groups and supplemented recently by the creation of several Ad Hoc Working Groups. Since its creation in 1992, the members of the GHTF have worked collaboratively to develop what is now ready to be called a global model for the regulation of medical devices.

One way to improve students' learning outcomes and well-being is to change teaching practices to allow students to become more active participants. We used an anatomy dissection course to test a cooperative group work method in which first-year veterinary students took turns leading their peer group and were each responsible for teaching the anatomy of a particular topographic region. The important blood vessels, lymphatic system, and nerves of each region of the body were covered. Students felt that exploration of the entire topographic region helped them to acquire a comprehensive understanding of the respiratory apparatus and the cardiovascular and nervous systems. Assigning individual tasks to each group member resulted in sharing the workload equally. Open-ended comments revealed that support from other group members was important for the students' learning experience, but the results also offered insight into a lack of constructive criticism. While teaching was considered challenging, and even a stress factor that hindered learning for some students, group work was generally held to be supportive of learning. The results suggest that more thorough instruction of students in their group work and in their individual tasks is required. Some students experienced difficulty in expressing their concerns openly and in seeking guidance from teachers, demonstrating the need for further investigation regarding students' self-regulation skills. Comments from the open-ended responses suggest that use of a cooperative learning method in anatomy dissection courses not only deepens student understanding of a subject but also offers first-year students an opportunity to practice the generic skills that will be needed in their future profession.

Identify useful concepts related to the emotional context facing family members of nursing home residents. These concepts can be used in future studies to design and test interventions that benefit family caregivers. Secondary data analyses of qualitative ethnographic data. Two nursing homes in a large Midwestern city; 8 months of data collection in each. 44 family members of nursing home residents whose health was considered, "declining." Role theory was used to design and help interpret the findings. Data included transcripts of conversations between family members and researchers and were analyzed using a coding scheme developed for the secondary analysis. Comments about emotions related to the social role of family member were grouped into three categories: relief related to admission, stress, and decision making support/stress. Subcategories of stress include the role strain associated with "competing concerns" and the psychological pressures of 1) witnessing the decline of a loved one in a nursing home, and 2) guilt about placement. Decision-making was discussed as a challenge which family members did not want to face alone; support from the resident, health care professionals, and other family members was appreciated. Family members may benefit from role reinforcement activities provided by nursing home staff and community members. All nursing home staff members (in particular social workers) and physicians are called upon to provide educationa and support regarding nursing home admissions, during the decline of the resident, and especially regarding medical decision-making. Community groups are asked to support the family member by offering assistance with concrete tasks (driving, visiting, etc.) and social support.

Oxytocin promotes group-serving dishonesty

To protect and promote the well-being of others, humans may bend the truth and behave unethically. Here we link such tendencies to oxytocin, a neuropeptide known to promote affiliation and cooperation with others. Using a simple coin-toss prediction task in which participants could dishonestly report their performance levels to benefit their group’s outcome, we tested the prediction that oxytocin increases group-serving dishonesty. A double-blind, placebo-controlled experiment allowing individuals to lie privately and anonymously to benefit themselves and fellow group members showed that healthy males (n = 60) receiving intranasal oxytocin, rather than placebo, lied more to benefit their group, and did so faster, yet did not necessarily do so because they expected reciprocal dishonesty from fellow group members. Treatment effects emerged when lying had financial consequences and money could be gained; when losses were at stake, individuals in placebo and oxytocin conditions lied to similar degrees. In a control condition (n = 60) in which dishonesty only benefited participants themselves, but not fellow group members, oxytocin did not influence lying. Together, these findings fit a functional perspective on morality revealing dishonesty to be plastic and rooted in evolved neurobiological circuitries, and align with work showing that oxytocin shifts the decision-maker’s focus from self to group interests. These findings highlight the role of bonding and cooperation in shaping dishonesty, providing insight into when and why collaboration turns into corruption. PMID:24706799

One of the most difficult tasks in cost-effectiveness analysis is the measurement of quality weights (utilities) for health states. The task is difficult because subjects often lack familiarity with health states they are asked to rate and because utilities measures such as the standard gamble, ask subjects to perform tasks that are complex and far from everyday experience. A large body of research suggests that computer methods can play an important role in explaining health states and measuring utilities. However, administering computer surveys to a "general public" sample, the most relevant sample for cost-effectiveness analysis, is logistically difficult. In this paper, we describe a software system designed to allow the study of general population preferences in a volunteer Internet survey panel. The approach, which relied on over sampling of ethnic groups and older members of the panel, produced a data set with an ethnically, chronologically and geographically diverse group of respondents, but was not successful in replicating the joint distribution of demographic patterns in the population.

We tested whether stereotypical situations would affect low-status group members' performance more strongly than high-status group members'. Experiment 1 and 2 tested this hypothesis using gender as a proxy of chronic social status and a gender-neutral task that has been randomly presented to favor boys (men superiority condition), favor girls (women superiority condition), or show no gender preference (control condition). Both experiments found that women’s (Experiment 1) and girls’ performance (Experiment 2) suffered more from the evoked stereotypes than did men's and boys’ ones. This result was replicated in Experiment 3, indicating that short men (low-status group) were more affected compared to tall men (high-status group). Additionally, men were more affected compared to women when they perceived height as a threat. Hence, individuals are more or less vulnerable to identity threats as a function of the chronic social status at play; enjoying a high status provides protection and endorsing a low one weakens individual performance in stereotypical situations.

Judicial virtues and decision-making in the VCAT Guardianship List.

PubMed

Polkinghorn, Richard

2014-06-01

The contemporary legal theory of virtue jurisprudence provides great insight into the proper practice of Australian tribunal members and the desired operation of tribunals. Virtue jurisprudence identifies the attributes of "good" tribunal members and provides guidance on how legal disputes should be decided. This article focuses on the fundamental virtues relevant to tribunal practice in the Guardianship List of the Victorian Civil and Administrative Tribunal. The special features of this tribunal jurisdiction, particularly the disadvantaged nature of its primary client group, require tribunal members to undertake a fact-finding, inquisitorial role, as well as a support and advisory role. Decision-makers must also become conversant with expert evidence and the process of testing expert evidence; they cannot simply defer to the expert on issues of decision-making capacity. This analysis considers the fundamental breaches of human rights that occur when tribunal members fail to execute this multilevel task properly.

Enacting cultural interests: how intergroup contact reduces prejudice by sparking interest in an out-group's culture.

Brannon, Tiffany N; Walton, Gregory M

2013-10-01

In the present research, we examined the hypothesis that cues of social connectedness to a member of another social group can spark interest in the group's culture, and that such interest, when freely enacted, contributes to reductions in intergroup prejudice. In two pilot studies and Experiment 1, we found that extant and desired cross-group friendships and cues of social connectedness to an out-group member predicted increased interest in the target group's culture. In Experiments 2 and 3, we manipulated cues of social connectedness between non-Latino American participants and a Latino American (i.e., Mexican American) peer and whether participants freely worked with this peer on a Mexican cultural task. This experience reduced the participants' implicit bias against Latinos, an effect that was mediated by increased cultural engagement, and, 6 months later in an unrelated context, improved intergroup outcomes (e.g., interest in interacting with Mexican Americans; Experiment 4). The Discussion section addresses the inter- and intragroup benefits of policies that encourage people to express and share diverse cultural interests in mainstream settings.

Organizational workforces are becoming increasingly dispersed. To facilitate communications among individuals or groups of people located in a number of different locations, teleconferencing technologies, such as audioconferencing, have been developed. The authors examined whether a structural group intervention, the stepladder technique, can facilitate the task performance of 4-person groups (n = 52) when using audioconferencing. Consistent with research conducted on face-to-face groups, the stepladder technique was found to facilitate the decision-making performance of groups interacting via audioconference. The authors postulated that certain structural elements of the stepladder technique compensate for obstacles inherent in nonvisual communications. Supplementary analyses examined best member influence and the existence of order of entry effects into the stepladder process.

During the IAU General Assembly in Rio de Janeiro in 2009, the members of Commission 22 established the Working Group on Meteor Shower Nomenclature, from what was formerly the Task Group on Meteor Shower Nomenclature. The Task Group had completed its mission to propose a first list of established meteor showers that could receive officially names. At the business meeting of Commission 22 the list of 64 established showers was approved and consequently officially accepted by the IAU. A two-step process is adopted for showers to receive an official name from the IAU: i) before publication, all new showers discussed in the literature are first added to the Working List of Meteor Showers, thereby receiving a unique name, IAU number and three-letter code; ii) all showers which come up to the verification criterion are selected for inclusion in the List of Established Meteor Showers, before being officially named at the next IAU General Assembly.

In August 2009, the American Association of Colleges of Pharmacy (AACP) Council of Sections established a Task Force to assess the current status of compounding education at its member institutions and to provide recommendations for future direction. The Task Force conducted a survey in late June 2010 of faculty members enrolled in the AACP Pharmaceutics and Pharmacy Practice sections to gain qualitative information of the current state of compounding education. The survey results were then organized around eight curricular topics for which the Task Force members provided interpretations and recommendations. A final report was sent to the AACP Council of Sections on February 15, 2011. This publication provides the information contained in that final report to the professional community. PMID:23049115

Student involvement in learning: Collaboration in science for PreService elementary teachers

The present study provided insights regarding the interactions that take place in collaborative science laboratory and regarding the outcome of such interactions. Science laboratory experiences structured by teachers have been criticized for allowing very little, if any, meaningful learning. However, this study showed that even structured laboratory experiments can provide insightful experience for students when conducted in a group setting that demanded interactive participation from all its members. The findings of the present study underscored the synergistic and supportive nature of collaborative groups. Here, students patiently repeated explanations to support the meaning construction on the part of their slower peers and elaborated their own understanding in the process; groups negotiated the meaning of observations and the corresponding theoretical explanations; students developed and practiced a range of social skills necessary in today’s workplace; and off-task behavior was thwarted by the group members motivated to work toward understanding rather than simply generating answers for task completion. The current findings suggest an increased use of collaborative learning environments for the teaching of science to elementary education majors. Some teachers have already made use of such settings in their laboratory teaching. However, collaborative learning should not be limited to the laboratory only, but be extended to more traditionally structured classes. The effects of such a switch in activity structures, increased quality of peer interaction, mastery of subject matter content, and decreased anxiety levels could well lead to better attitudes toward science among preservice elementary school teachers and eventually among their own students.

Recommendations on evidence needed to support measurement equivalence between electronic and paper-based patient-reported outcome (PRO) measures: ISPOR ePRO Good Research Practices Task Force report.

Patient-reported outcomes (PROs) are the consequences of disease and/or its treatment as reported by the patient. The importance of PRO measures in clinical trials for new drugs, biological agents, and devices was underscored by the release of the US Food and Drug Administration's draft guidance for industry titled "Patient-Reported Outcome Measures: Use in Medical Product Development to Support Labeling Claims." The intent of the guidance was to describe how the FDA will evaluate the appropriateness and adequacy of PRO measures used as effectiveness end points in clinical trials. In response to the expressed need of ISPOR members for further clarification of several aspects of the draft guidance, ISPOR's Health Science Policy Council created three task forces, one of which was charged with addressing the implications of the draft guidance for the collection of PRO data using electronic data capture modes of administration (ePRO). The objective of this report is to present recommendations from ISPOR's ePRO Good Research Practices Task Force regarding the evidence necessary to support the comparability, or measurement equivalence, of ePROs to the paper-based PRO measures from which they were adapted. The task force was composed of the leadership team of ISPOR's ePRO Working Group and members of another group (i.e., ePRO Consensus Development Working Group) that had already begun to develop recommendations regarding ePRO good research practices. The resulting task force membership reflected a broad array of backgrounds, perspectives, and expertise that enriched the development of this report. The prior work became the starting point for the Task Force report. A subset of the task force members became the writing team that prepared subsequent iterations of the report that were distributed to the full task force for review and feedback. In addition, review beyond the task force was sought and obtained. Along with a presentation and discussion period at an ISPOR meeting, a draft version of the full report was distributed to roughly 220 members of a reviewer group. The reviewer group comprised individuals who had responded to an emailed invitation to the full membership of ISPOR. This Task Force report reflects the extensive internal and external input received during the 16-month good research practices development process. RESULTS/RECOMMENDATIONS: An ePRO questionnaire that has been adapted from a paper-based questionnaire ought to produce data that are equivalent or superior (e.g., higher reliability) to the data produced from the original paper version. Measurement equivalence is a function of the comparability of the psychometric properties of the data obtained via the original and adapted administration mode. This comparability is driven by the amount of modification to the content and format of the original paper PRO questionnaire required during the migration process. The magnitude of a particular modification is defined with reference to its potential effect on the content, meaning, or interpretation of the measure's items and/or scales. Based on the magnitude of the modification, evidence for measurement equivalence can be generated through combinations of the following: cognitive debriefing/testing, usability testing, equivalence testing, or, if substantial modifications have been made, full psychometric testing. As long as only minor modifications were made to the measure during the migration process, a substantial body of existing evidence suggests that the psychometric properties of the original measure will still hold for the ePRO version. Hence, an evaluation limited to cognitive debriefing and usability testing only may be sufficient. However, where more substantive changes in the migration process has occurred, confirming that the adaptation to the ePRO format did not introduce significant response bias and that the two modes of administration produce essentially equivalent results is necessary. Recommendations regarding the study designs and statistical approaches for assessing measurement equivalence are provided. The electronic administration of PRO measures offers many advantages over paper administration. We provide a general framework for decisions regarding the level of evidence needed to support modifications that are made to PRO measures when they are migrated from paper to ePRO devices. The key issues include: 1) the determination of the extent of modification required to administer the PRO on the ePRO device and 2) the selection and implementation of an effective strategy for testing the measurement equivalence of the two modes of administration. We hope that these good research practice recommendations provide a path forward for researchers interested in migrating PRO measures to electronic data collection platforms.

Innovation in values based public health nursing student selection: A qualitative evaluation of candidate and selection panel member perspectives.

Values based recruitment emerges from the premise that a high degree of value congruence, or the extent to which an individual's values are similar to those of the health organization in which they work, leads to organizational effectiveness. The aim of this evaluation was to explore how candidates and selection panel members experienced and perceived innovative methods of values based public health nursing student selection. The evaluation was framed by a qualitative exploratory design involving semi-structured interviews and a group exercise. Data were thematically analyzed. Eight semi-structured interviews were conducted with selection panel members. Twenty-two successful candidates took part in a group exercise. The use of photo elicitation interviews and situational judgment questions in the context of selection to a university-run public health nursing educational program was explored. While candidates were ambivalent about the use of photo elicitation interviews, with some misunderstanding the task, selection panel members saw the benefits for improving candidate expression and reducing gaming and deception. Situational interview questions were endorsed by candidates and selection panel members due to their fidelity to real-life problems and the ability of panel members to discern value congruence from candidates' responses. Both techniques offered innovative solutions to candidate selection for entry to the public health nursing education program. © 2018 Wiley Periodicals, Inc.

Tham and Tegner proposed the Baking Tray Task (BTT) as a fast simple assessment test for detecting spatial negligence. However, very few studies have examined its validity as a diagnostic test. To analyse the diagnostic validity of the BTT by measuring its specificity and sensitivity in a sample of subjects with right hemisphere strokes. Forty-eight patients with right hemisphere vascular lesions were distributed in two groups (negligence group, n = 35; non-negligence group, n = 13) according to the scores obtained in a battery of visuospatial examination tests. The participants' performance on the BTT was compared with that of a healthy control group (n = 12). The results showed a high level of sensitivity of the BTT, but low specificity. The performance on the BTT of eight of the 13 members of the non-negligence group was suggestive of negligence. The BTT has proved to be a sensitive test for the detection of spatial negligence. Yet, based on its low specificity, its use alone as a single diagnostic test is not recommended.

Oxytocin promotes human ethnocentrism

2011-01-01

Human ethnocentrism—the tendency to view one's group as centrally important and superior to other groups—creates intergroup bias that fuels prejudice, xenophobia, and intergroup violence. Grounded in the idea that ethnocentrism also facilitates within-group trust, cooperation, and coordination, we conjecture that ethnocentrism may be modulated by brain oxytocin, a peptide shown to promote cooperation among in-group members. In double-blind, placebo-controlled designs, males self-administered oxytocin or placebo and privately performed computer-guided tasks to gauge different manifestations of ethnocentric in-group favoritism as well as out-group derogation. Experiments 1 and 2 used the Implicit Association Test to assess in-group favoritism and out-group derogation. Experiment 3 used the infrahumanization task to assess the extent to which humans ascribe secondary, uniquely human emotions to their in-group and to an out-group. Experiments 4 and 5 confronted participants with the option to save the life of a larger collective by sacrificing one individual, nominated as in-group or as out-group. Results show that oxytocin creates intergroup bias because oxytocin motivates in-group favoritism and, to a lesser extent, out-group derogation. These findings call into question the view of oxytocin as an indiscriminate “love drug” or “cuddle chemical” and suggest that oxytocin has a role in the emergence of intergroup conflict and violence.

The "social lubrication" function of alcohol during interpersonal interactions is well documented. However, less is known about the effects of alcohol consumption on group-level behavior. Empirical findings from social psychological literature suggest that individuals tend to favor those who are considered as members of their own social group. Not yet evaluated is how alcohol intoxication interacts with this group-level bias. Therefore, the current study examined experimentally the effects of intoxication on group bias. Ninety-four individuals (M age = 20.18, SD = 2.36, 55 women, 39 men) were randomly assigned to consume an alcoholic (n = 48) or a placebo (n = 46) drink before completing manipulated allocation matrices, a task which measured the distribution of hypothetical monetary awards based on social groups. Results point to an interaction between drink condition and social group identification, whereby identification was significantly associated with in-group favoritism among intoxicated individuals only. Following alcohol consumption, participants with higher identification with their social group were more likely to demonstrate allocation strategies that favored their own group members. However, nonsignificant effects were observed for those in the placebo condition. The findings highlight how alcohol intoxication may facilitate group bias that results from social group identification. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

A review of the literature related to in-hand manipulation (IHM) revealed that there is no assessment which specifically measures this construct in the adult population. This study reports the face and content validity of an IHM assessment for adults with impaired hand function based on expert opinion. The definition of IHM skills, assessment tasks and scoring methods identified from literature was discussed in a focus group (n = 4) to establish face validity. An expert panel (n = 16) reviewed the content validity of the proposed assessment; evaluating the representativeness and relevance of encompassing the IHM skills in the proposed assessment tasks, the clarity and importance to daily life of the task and the clarity and applicability to clinical environment of the scoring method. The content validity was calculated using the content validity index for both the individual task and all tasks together (I-CVI and S-CVI). Feedback was incorporated to create the assessment. The focus group members agreed to include 10 assessment tasks that covered all IHM skills. In the expert panel review, all tasks received an I-CVI above 0.78 and S-CVI above 0.80 in representativeness and relevance ratings, representing good content validity. With the comments from the expert panel, tasks were modified to improve the clarity and importance to daily life. A four-point Likert scale was identified for assessing both the completion of the assessment tasks and the quality of IHM skills within the task performance. Face and content validity were established in this new IHM assessment. Further studies to examine psychometric properties and use within clinical practice are recommended. © 2018 Occupational Therapy Australia.

In a collaboration the size of CMS (approx. 3000 users, and almost 100 computing centres of varying size) communication and accurate information about the sites it has access to is vital in co-ordinating the multitude of computing tasks required for smooth running. SiteDB is a tool developed by CMS to track sites available to the collaboration, the allocation to CMS of resources available at those sites and the associations between CMS members and the sites (as either a manager/operator of the site or a member of a group associated to the site). It is used to track the roles a person has for an associated site or group. SiteDB eases the coordination load for the operations teams by providing a consistent interface to manage communication with the people working at a site, by identifying who is responsible for a given task or service at a site and by offering a uniform interface to information on CMS contacts and sites. SiteDB provides api's and reports for other CMS tools to use to access the information it contains, for instance enabling CRAB to use "user friendly" names when black/white listing CE's, providing role based authentication and authorisation for other web based services and populating various troubleshooting squads in external ticketing systems in use daily by CMS Computing operations.

Since 1990, the EC-US Task Force on Biotechnology Research has been coordinating transatlantic efforts to guide and exploit the ongoing revolution in biotechnology and the life sciences. The Task Force was established in June 1990 by the European Commission and the White House Office of Science and Technology Policy. The Task Force has acted as an effective forum for discussion, coordination, and development of new ideas for the last 18 years. Task Force members are European Commission and US Government science and technology administrators who meet annually to enhance communication across the Atlantic, and to encourage collaborative research. Through sponsoringmore » workshops, and other activities, the Task Force also brings together scientific leaders and early career researchers from both sides of the Atlantic to forecast research challenges and opportunities and to promote better links between researchers. Over the years, by keeping a focus on the future of science, the Task Force has played a key role in establishing a diverse range of emerging scientific fields, including biodiversity research, neuroinformatics, genomics, nanobiotechnology, neonatal immunology, transkingdom molecular biology, biologically-based fuels, and environmental biotechnology. The EC-US Task Force has sponsored a number of Working Groups on topics of mutual transatlantic interest. The idea to create a Working Group on Environmental Biotechnology research was discussed in the Task Force meeting of October 1993. The EC-US Working Group on Environmental Biotechnology set as its mission 'To train the next generation of leaders in environmental biotechnology in the United States and the European Union to work collaboratively across the Atlantic.' Since 1995, the Working Group supported three kinds of activities, all of which focus one early career scientists: (1) Workshops on the use of molecular methods and genomics in environmental biotechnology; (2) Short courses with theoretical, laboratory and field elements; and (3) Short term exchange fellowships. The short term exchange fellowships were created to enable young scientists to develop collaborations with colleagues across the Atlantic and to learn a new skill or expertise in the area of environmental biotechnology.« less

Approaches to mitigating the likelihood of psychosocial problems during space missions emphasize preflight measures such as team training and team composition. Additionally, it may be necessary to monitor team interactions during missions for signs of interpersonal stress. The present research was conducted to identify features in team members' communications indicative of team functioning. Team interactions were studied in the context of six computer-simulated search and rescue missions. There were 12 teams of 4 U.S. men who participated; however, the present analyses contrast the top two teams with the two least successful teams. Communications between team members were analyzed using linguistic analysis software and a coding scheme developed to characterize task-related and social dimensions of team interactions. Coding reliability was established by having two raters independently code three transcripts. Between-rater agreement ranged from 78.1 to 97.9%. Team performance was significantly associated with team members' task-related communications, specifically with the extent to which task-critical information was shared. Successful and unsuccessful teams also showed different interactive patterns, in particular concerning the frequencies of elaborations and no-responses. Moreover, task success was negatively correlated with variability in team members' word count, and positively correlated with the number of positive emotion words and the frequency of assenting relative to dissenting responses. Analyses isolated certain task-related and social features of team communication related to team functioning. Team success was associated with the extent to which team members shared task-critical information, equally participated and built on each other's contributions, showed agreement, and positive affect.

The purpose of the present study was to determine the value of virtual reality (VR) training for a multimodality training program of basic laparoscopic surgery. Participants in a two-day multimodality training for laparoscopic surgery used box trainers, live animal training, and cadaveric training on the pulsating organ perfusion (POP) trainer in a structured and standardized training program. The participants were divided into two groups. The VR group (n = 13) also practiced with VR training during the program, whereas the control group (n = 14) did not use VR training. The training modalities were assessed using questionnaires with a five-point Likert scale after the program. Concerning VR training, members of the control group assessed their expectations, whereas the VR group assessed the actual experience of using it. Skills performance was evaluated with five standardized test tasks in a live porcine model before (pre-test) and after (post-test) the training program. Laparoscopic skills were measured by task completion time and a general performance score for each task. Baseline tests were compared with laparoscopic experience of all participants for construct validity of the skills test. The expected benefit from VR training of the control group was higher than the experienced benefit of the VR group. Box and POP training received better ratings from the VR group than from the control group for some purposes. Both groups improved their skill parameters significantly from pre-training to post-training tests [score +17 % (P < 0.01), time -29 % (P < 0.01)]. No significant difference was found between the two groups for laparoscopic skills improvement except for the score in the instrument coordination task. Construct validity of the skills test was significant for both time and score. At its current level of performance, VR training does not meet expectations. No additional benefit was observed from VR training in our multimodality training program.

The proportion of elderly people in the population has increased rapidly in the last century and consequently “healthy aging” is expected to become a critical area of research in neuroscience. Evidence reveals how healthy aging depends on three main behavioral factors: social lifestyle, cognitive activity, and physical activity. In this study, we focused on the role of cognitive activity, concentrating specifically on educational and occupational attainment factors, which were considered two of the main pillars of cognitive reserve (CR). Twenty-one subjects with similar rates of social lifestyle, physical and cognitive activity were selected from a sample of 55 healthy adults. These subjects were divided into two groups according to their level of CR; one group comprised subjects with high CR (9 members) and the other one contained those with low CR (12 members). To evaluate the cortical brain connectivity network, all participants were recorded by Magnetoencephalography (MEG) while they performed a memory task (modified version of the Sternberg's Task). We then applied two algorithms [Phase Locking Value (PLV) and Phase Lag Index (PLI)] to study the dynamics of functional connectivity. In response to the same task, the subjects with lower CR presented higher functional connectivity than those with higher CR. These results may indicate that participants with low CR needed a greater “effort” than those with high CR to achieve the same level of cognitive performance. Therefore, we conclude that CR contributes to the modulation of the functional connectivity patterns of the aging brain. PMID:24982632

Ethnic identity in adolescents and adults: review of research.

PubMed

Phinney, J S

1990-11-01

Ethnic identity is central to the psychological functioning of members of ethnic and racial minority groups, but research on the topic is fragmentary and inconclusive. This article is a review of 70 studies of ethnic identity published in refereed journals since 1972. The author discusses the ways in which ethnic identity has been defined and conceptualized, the components that have been measured, and empirical findings. The task of understanding ethnic identity is complicated because the uniqueness that distinguishes each group makes it difficult to draw general conclusions. A focus on the common elements that apply across groups could lead to a better understanding of ethnic identity.

Why do I always have the best ideas? The role of idea quality in unconscious plagiarism.

PubMed

Perfect, Timothy J; Stark, Louisa-Jayne

Groups of individuals often work together to generate solutions to a problem. Subsequently, one member of the group can plagiarise another either by recalling that person's idea as their own (recall-own plagiarism), or by generating a novel solution that duplicates a previous idea (generate-new plagiarism). The current study examines the extent to which these forms of plagiarism are influenced by the quality of the ideas. Groups of participants initially generated ideas, prior to an elaboration phase in which idea quality was manipulated in two ways: participants received feedback on the quality of the ideas as rated by independent judges, and they generated improvements to a subset of the ideas. Unconscious plagiarism was measured in recall-own and generate-new tasks. For recall, idea improvement led to increased plagiarism, while for the generate-new task, the independent ratings influenced plagiarism. These data indicate that different source-judgement processes underlie the two forms of plagiarism, neither of which can be reduced simply to memory strength.

What's good for the goose may not be as good for the gander: the benefits of self-monitoring for men and women in task groups and dyadic conflicts.

PubMed

Flynn, Francis J; Ames, Daniel R

2006-03-01

The authors posit that women can rely on self-monitoring to overcome negative gender stereotypes in certain performance contexts. In a study of mixed-sex task groups, the authors found that female group members who were high self-monitors were considered more influential and more valuable contributors than women who were low self-monitors. Men benefited relatively less from self-monitoring behavior. In an experimental study of dyadic negotiations, the authors found that women who were high self-monitors performed better than women who were low self-monitors, particularly when they were negotiating over a fixed pool of resources, whereas men did not benefit as much from self-monitoring. Further analyses suggest that high self-monitoring women altered their behavior in these negotiations--when their partner behaved assertively, they increased their level of assertiveness, whereas men and low self-monitoring women did not alter their behavior.

In intergroup conflict, self-sacrifice is stronger among pro-social individuals, and parochial altruism emerges especially among cognitively taxed individuals

Parochial altruism is decomposed in a tendency to benefit the in-group along with a tendency to ignore, derogate, and harm rivaling out-groups. Building off recent work suggesting that decisions to cooperate can be relatively fast and intuitive, we examine parochial altruism in intergroup conflict when cognitive deliberation is rendered difficult or not. Predictions were tested in an experiment using an incentivized Intergroup Prisoner’s Dilemma–Maximizing Differences Game with 95 subjects classified as either pro-social or pro-self being randomly allocated to high vs. low impulse-control conditions. Results showed, first of all, that self-sacrificial decisions to contribute were made faster than decisions not to contribute, and that faster decision time associated with more positive expectations of in-group members. Second, we observed that lowering impulse control with a difficult rather than easy Stroop Task increased the amount contributed to a pool that benefited in-group members while harming out-group members; thus reducing deliberation increased parochial altruism. Finally, results replicated earlier work showing that especially pro-social (vs. pro-self) individuals contributed more to the in-group and did not lower their contributions to the between-group pool that benefitted their in-group and, simultaneously, hurt the out-group. This pattern emerged independent of their impulse control. Thus, (in-group bounded) cooperation is more prominent among individuals with strong rather than weak other-regarding preferences. Moreover, the intuitive tendency to cooperate may have evolved in the context of intergroup conflict and therefore is sharp-edged—in-group bounded and including willingness to aggress out-groups.

The authors develop and test theoretical extensions of the relationships of task conflict, relationship conflict, and 2 dimensions of team effectiveness (performance and team-member satisfaction) among 2 samples of work teams in Taiwan and Indonesia. Findings show that relationship conflict moderates the task conflict-team performance relationship. Specifically, the relationship is curvilinear in the shape of an inverted U when relationship conflict is low, but the relationship is linear and negative when relationship conflict is high. The results for team-member satisfaction are more equivocal, but the findings provide some evidence that relationship conflict exacerbates the negative relationship between task conflict and team-member satisfaction.

Vicarious intergroup contact and the role of authorities in prejudice reduction.

PubMed

Gómez, Angel; Huici, Carmen

2008-05-01

The present study focuses on the effect of vicarious intergroup contact and the support of an authority figure on the improvement of outgroup and meta-stereotype evaluations. Meta-stereotype refers to the shared beliefs of ingroup members about how they consider outgroup members to perceive their group. Three preliminary studies were carried out to determine desirable and undesirable characteristics for a good basketball performance, the task that best demonstrates the application of these characteristics, and the two groups (basketball teams) that should be involved in the vicarious intergroup contact. Fans of one of the basketball teams participated in the current study. Vicarious intergroup contact improved outgroup and meta-stereotype evaluations as compared with a no contact condition. In addition, the positive effects of vicarious intergroup contact significantly increased when it was supported by an authority figure. More importantly, our study also shows that the improvement of outgroup evaluation was partially mediated by changes on meta-stereotypes.

This study investigated changes in motor and cognitive skills, anxiety levels, and quality of life perception among patients with Parkinson's Disease (PD) following training with different commercial gaming devices-Nintendo Wii™ and Xbox Kinect™. We used a quasi-experimental, simple blinded clinical trial, dividing 27 patients with PD into three equal groups of nine members: (a) Nintendo Wii™, (b) Xbox Kinect™, and (c) control group. After pretests, experimental group participants spent 10 sessions playing four games of the selected gaming device, while control group participants received no intervention. Only those engaged with the Nintendo Wii™ significantly improved their performance on single and dual task gait tests, decreased anxiety levels, and improved memory, attention, and reversibility. The control group showed no changes on any measures.

There are few detailed workforce studies of specialty fields within professional psychology, and none have been reported for pediatric psychology since 2006. Availability of such data could facilitate more-informed decision making by students and trainees, psychologists pursuing employment opportunities, and psychologists involved in employment or compensation negotiations. This article describes the work of a task force of the American Psychological Association (APA) Division 54 (Society of Pediatric Psychology) in the design, construction, pretesting, distribution, and data management for the Society of Pediatric Psychology (SPP) Workforce Survey. The 18-member task force was established to design and implement a workforce survey that balanced needs for breadth, clarity, brevity, and protection of confidentiality. The survey solicits information about demographic characteristics; training, licensure and certifications; employment settings, responsibilities, and productivity metrics; compensation; and employment satisfaction. A survey link was distributed via e-mail to full members of the SPP in June 2015. A total of 404 members (32.3% return rate) completed the survey. This article focuses on the development, methodology, and respondent characteristics for this 1st administration of the workforce survey. Separate articles will report detailed analyses of the survey results such as compensation and work satisfaction. Future distributions of the survey will enable compilation of a longitudinal database to track changes in the profession. SPP members and others may propose additional analyses of these data. This work may provide guidance to other groups of specialized psychologists who may wish to implement similar initiatives. PMID:28066693

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.

Teamwork, a skill critical for quality patient care, is recognized as a core competency by the Accreditation Council for Graduate Medical Education (ACGME). To date, there is no consensus on how to effectively teach these skills in a forum that engages learners, immerses members in life-like activities, and builds both trust and rapport. Recreational ‘Escape Rooms’ have gained popularity in creating a life-like environment that rewards players for working together, solving puzzles, and completing successions of mind-bending tasks in order to effectively ‘escape the room’ in the time allotted. In this regard, escape rooms share many parallels with the multitasking and teamwork that is essential for a successful emergency department (ED) shift. A pilot group of nine emergency medicine (EM) residents and one senior EM faculty member underwent a commercial escape room as part of a team-building exercise in January 2018. The escape room required participants to practice teamwork, communication, task delegation, and critical thinking to tackle waves of increasingly complex puzzles, ranging from hidden objects, physical object assembly (i.e., jigsaw puzzles), and symbol matching. Activities required members to recognize and utilize the collective experiences, skills, knowledge base, and physical abilities of the group. After the game, players underwent a structured ‘game-master’ debriefing facilitated by an employee of the commercial escape room; this was followed by a post-event survey facilitated by a faculty member, which focused on participants’ feelings, experiences, and problem-solving techniques. Escape rooms afford learners the opportunity to engage in an activity that rewards teamwork and effective leadership through experiences that directly link to specific ACGME milestones and educational learning theories. EM participants were engaged in the activity and felt that the escape room reproduced an environment analogous to the ED. The debriefing that followed the activity provided a satisfactory conclusion to the experience; but learners preferred a more organized debriefing format that provided them with constructive and specific feedback on their performance.

In 1989, the newly formed BAA Campaign for Dark Skies (CfDS) asked astronomical groups across the UK to nominate members who would actively spread the dark-skies message. Thirty-one 'regional officers' emerged, scattered from Plymouth to near John O'Groats, and from North Wales to the Wash. An unenviable task faced them: a CfDS survey had concluded that more than 90% of British observers, astronomers or not, experienced some degree of skyglow.

Is task-shifting a solution to the health workers' shortage in Northern Ghana?

Okyere, Eunice; Mwanri, Lillian; Ward, Paul

2017-01-01

To explore the experiences and perceptions of health workers and implementers of task-shifting in rural health facilities in Upper East Region, Ghana. Data was collected through field interviews. A total of sixty eight (68) in-depth interviews were conducted with health workers' in primary health care facilities (health centres); Four in-depth interviews with key persons involved in staff management was conducted to understand how task-shifting is organised including its strengths and challenges. The health workers interview guide was designed with the aim of getting data on official tasks of health workers, additional tasks assigned to them, how they perceive these tasks, and the challenges associated with the practice of task-shifting. Task-shifting is a practice being used across the health facilities in the study area to help reduce the impact of insufficient health workers. Generally, health workers had a comprehensive training that supported the organisation of task-shifting. However, staff members' are sometimes engaged in tasks above their level of training and beyond their actual job descriptions. Adequate training is usually not provided before additional tasks are assigned to staff members. Whilst some health workers perceived the additional tasks they performed as an opportunity to learn new skills, others described these as stressful and overburdening. Task-shifting has the potential to contribute to addressing the insufficient health workforce, and thereby improving health delivery system where the procedures are well defined and staff members work in a coordinated and organised manner. The provision of adequate training and supervision for health workers is important in order to improve their expertise before additional tasks are assigned to them so that the quality of care would not be compromised.

Overview of crew member energy expenditure during Shuttle Flight 61-8 EASE/ACCESS task performance

1987-01-01

The energy expenditure of the Shuttle Flight 61-B crewmembers during the extravehicular performance of Experimental Assembly of Structures in EVA (EASE) and Assembly Concept of Construction of Space Structures (ACCESS) construction system tasks are reported. These data consist of metabolic rate time profiles correlated with specific EASE and ACCESS tasks and crew comments. Average extravehicular activity metabolic rates are computed and compared with those reported from previous Apollo, Shylab, and Shuttle flights. These data reflect total energy expenditure and not that of individual muscle groups such as hand and forearm. When correlated with specific EVA tasks and subtasks, the metabolic profile data is expected to be useful in planning future EVA protocols. For example, after experiencing high work rates and apparent overheating during some Gemini EVAs, it was found useful to carefully monitor work rates in subsequent flights to assess the adequacy of cooling garments and as an aid to preplanning EVA procedures. This presentation is represented by graphs and charts.

Modes of Decision Making Used by Nursing Home Residents and Their Families When Confronted With Potential Hospital Readmission.

The purpose of the current study was to characterize the decision-making processes used by nursing home (NH) residents and their families when confronted with an acute change in condition and the choice of transfer to the hospital or treatment in the NH. Using cognitive task analysis, 96 residents and 75 family members from 19 NHs were asked how they would make this choice. Fifty-one residents (53%) and 61 family members (81%) used a deliberative mode characterized by seeking information and weighing risks and benefits. Ten residents (10%) and five family members (7%) used a predominantly emotion-based mode characterized by references to feelings and prior experiences in these facilities. Thirty-six residents (38%) and nine family members (12%) delegated the decision to a family member or provider. Age and resident/family status were associated with mode used; transfer choice, gender, religion, education, and ethnic group were not. Although classic theories of information processing posit two modes of decision making, deliberative and affective, the current data suggest a third mode, that of delegating the decision to trusted others, particularly family members and providers.

Objectives To examine the experiences of low-income Part D beneficiaries with mental illness and their use of community helpers to access prescription medicines. Methods Individual semi-structured interviews were conducted with 26 Medicare beneficiaries with mental illness in community settings. The transcripts were analyzed for content related to community help-seeking and attitudes toward family and professional helpers. Results Medicare Part D beneficiaries with mental illness used the assistance of community helpers extensively. Pharmacists, nurses, community mental health case managers, and family members assisted beneficiaries with understanding their benefit plans and interpreting paperwork from plans and government agencies. Community helpers also assisted with tasks related to medication adherence. Mental health consumers appreciated the help that they received from family members and professionals. Conclusion This group of Medicare beneficiaries would have experienced difficulty in using their benefits and obtaining their medication without considerable help from professionals and family members in the community.

Involving Members of the Public in Health Economics Research: Insights from Selecting Health States for Valuation to Estimate Quality-Adjusted Life-Year (QALY) Weights.

PubMed

Goodwin, Elizabeth; Boddy, Kate; Tatnell, Lynn; Hawton, Annie

2018-04-01

Over recent years, public involvement in health research has expanded considerably. However, public involvement in designing and conducting health economics research is seldom reported. Here we describe the development, delivery and assessment of an approach for involving people in a clearly defined piece of health economics research: selecting health states for valuation in estimating quality-adjusted life-years (QALYs). This involvement formed part of a study to develop a condition-specific preference-based measure of health-related quality of life, the Multiple Sclerosis Impact Scale (MSIS-8D), and the work reported here relates to the identification of plausible, or realistic, health states for valuation. An Expert Panel of three people with multiple sclerosis (MS) was recruited from a local involvement network, and two health economists designed an interactive task that enabled the Panel to identify health states that were implausible, or unlikely to be experienced. Following some initial confusion over terminology, which was resolved by discussion with the Panel, the task worked well and can be adapted to select health states for valuation in the development of any preference-based measure. As part of the involvement process, five themes were identified by the Panel members and the researchers which summarised our experiences of public involvement in this health economics research example: proportionality, task design, prior involvement, protectiveness and partnerships. These are described in the paper, along with their practical implications for involving members of the public in health economics research. Our experience demonstrates how members of the public and health economists can work together to improve the validity of health economics research. Plain Language Summary It has become commonplace to involve members of the public in health service research. However, published reports of involving people in designing health economics research are rare. We describe how we designed a way of involving people in a particular piece of health economics research.The aim of the work was to produce descriptions of different states of health experienced by people with multiple sclerosis (MS). These descriptions have since been rated in terms of how good or bad they are in a way that can be used by the National Institute for Health and Care Excellence (NICE) to make decisions about what services to fund on the NHS.We formed a panel of three people with MS, and designed a task to help the group produce health descriptions likely to be experienced by people with MS. After discussion about jargon, and working together to find more layman's terms, the task worked well, and can be adapted to produce health descriptions for any condition.We identified some key themes about working together that give insights into how members of the public can be involved in health economics research, and show the importance of their involvement in improving the relevance of this research.

Cluster management.

PubMed

Katz, R

1992-11-01

Cluster management is a management model that fosters decentralization of management, develops leadership potential of staff, and creates ownership of unit-based goals. Unlike shared governance models, there is no formal structure created by committees and it is less threatening for managers. There are two parts to the cluster management model. One is the formation of cluster groups, consisting of all staff and facilitated by a cluster leader. The cluster groups function for communication and problem-solving. The second part of the cluster management model is the creation of task forces. These task forces are designed to work on short-term goals, usually in response to solving one of the unit's goals. Sometimes the task forces are used for quality improvement or system problems. Clusters are groups of not more than five or six staff members, facilitated by a cluster leader. A cluster is made up of individuals who work the same shift. For example, people with job titles who work days would be in a cluster. There would be registered nurses, licensed practical nurses, nursing assistants, and unit clerks in the cluster. The cluster leader is chosen by the manager based on certain criteria and is trained for this specialized role. The concept of cluster management, criteria for choosing leaders, training for leaders, using cluster groups to solve quality improvement issues, and the learning process necessary for manager support are described.

Role of meaningful subgroups in explaining differences in perceived variability for in-groups and out-groups.

PubMed

Park, B; Ryan, C S; Judd, C M

1992-10-01

Five aspects of the complexity of the knowledge representation of business and engineering majors were examined to see whether these differed by group membership and whether these differences were related to differences in perceived variability. Significantly more subgroups were generated when describing the in-group than the out-group; this difference predicted the relative tendency to see the in-group as more variable, and when controlled for statistically, out-group homogeneity effects were eliminated. Familiarity, redundancy, number of attributes used to describe the group, and the deviance of the subgroups from the larger group generally showed differences for in-group and out-group but did not show consistent evidence of mediation. In a 2nd study, Ss who were asked to sort group members into meaningful subgroups perceived greater variability relative to those who did not perform the sorting task.

Content-related interactions and methods of reasoning within self-initiated organic chemistry study groups

NASA Astrophysics Data System (ADS)

Christian, Karen Jeanne

2011-12-01

Students often use study groups to prepare for class or exams; yet to date, we know very little about how these groups actually function. This study looked at the ways in which undergraduate organic chemistry students prepared for exams through self-initiated study groups. We sought to characterize the methods of social regulation, levels of content processing, and types of reasoning processes used by students within their groups. Our analysis showed that groups engaged in predominantly three types of interactions when discussing chemistry content: co-construction, teaching, and tutoring. Although each group engaged in each of these types of interactions at some point, their prevalence varied between groups and group members. Our analysis suggests that the types of interactions that were most common depended on the relative content knowledge of the group members as well as on the difficulty of the tasks in which they were engaged. Additionally, we were interested in characterizing the reasoning methods used by students within their study groups. We found that students used a combination of three content-relevant methods of reasoning: model-based reasoning, case-based reasoning, or rule-based reasoning, in conjunction with one chemically-irrelevant method of reasoning: symbol-based reasoning. The most common way for groups to reason was to use rules, whereas the least common way was for students to work from a model. In general, student reasoning correlated strongly to the subject matter to which students were paying attention, and was only weakly related to student interactions. Overall, results from this study may help instructors to construct appropriate tasks to guide what and how students study outside of the classroom. We found that students had a decidedly strategic approach in their study groups, relying heavily on material provided by their instructors, and using the reasoning strategies that resulted in the lowest levels of content processing. We suggest that instructors create more opportunities for students to explore model-based reasoning, and to create opportunities for students to be able to co-construct in a collaborative manner within the context of their organic chemistry course.

This report describes the development and preliminary application of an experimental test bed for modeling human behavior in the context of a computer generated environment to analyze the effects of variations in communication modalities, incentives and stressful conditions. In addition to detailing the methodological development of a simulated task environment that provides for electronic monitoring and recording of individual and group behavior, the initial substantive findings from an experimental analysis of distributed interactive communication in simulated space dwelling groups are described. Crews of three members each (male and female) participated in simulated "planetary missions" based upon a synthetic scenario task that required identification, collection, and analysis of geologic specimens with a range of grade values. The results of these preliminary studies showed clearly that cooperative and productive interactions were maintained between individually isolated and distributed individuals communicating and problem-solving effectively in a computer-generated "planetary" environment over extended time intervals without benefit of one another's physical presence. Studies on communication channel constraints confirmed the functional interchangeability between available modalities with the highest degree of interchangeability occurring between Audio and Text modes of communication. The effects of task-related incentives were determined by the conditions under which they were available with Positive Incentives effectively attenuating decrements in performance under stressful time pressure. c2003 Elsevier Ltd.

The purpose of this study was to evaluate a global deficit in sequential processing as candidate endophenotypein a family with familial childhood apraxia of speech (CAS). Of 10 adults and 13 children in a three-generational family with speech sound disorder (SSD) consistent with CAS, 3 adults and 6 children had past or present SSD diagnoses. Two preschoolers with unremediated CAS showed a high number of sequencing errors during single-word production. Performance on tasks with high sequential processing loads differentiated between the affected and unaffected family members, whereas there were no group differences in tasks with low processing loads. Adults with a history of SSD produced more sequencing errors during nonword and multisyllabic real word imitation, compared to those without such a history. Results are consistent with a global deficit in sequential processing that influences speech development as well as cognitive and linguistic processing. PMID:23339324

Interdisciplinary group approach to occupational safety and health administration standard: reductions in cost and duplication of effort.

After the December 1991 publication of the Occupational Safety and Health Administration standard, "Occupational Exposure to Bloodborne Pathogens; Final Rule," medical facilities in the United States were challenged to meet the mandates of this standard with massive training in a relatively short time. An interdisciplinary task force composed of representative members of a major health maintenance organization was charged with the task of developing a training plan for 11 Southern California medical centers and their 42 satellite medical offices. The task force ultimately developed, refined, and distributed a Trainer Guidebook that could be used by a variety of disciplines. This guidebook provided a method by which the information could be disseminated concisely, thoroughly, and promptly. The processes used in this project can be applied to other health care educational situations. The purpose of this article is to share these processes.

When remembering the past suppresses memory for future actions.

PubMed

Utsumi, Kenta; Saito, Satoru

2016-01-01

Remembering planned actions at the correct time in the future is an integral component of prospective cognition. Recent studies on future remembering have led to suggestions that prospective cognition might be based on past experience. To test this hypothesis, we focused on retrieval-induced forgetting (RIF), which usually indicates that remembering past events suppresses memory for related but different past events. The current study assessed RIF in two kinds of event-based prospective memory (PM) tasks using either focal or non-focal cues for ongoing tasks. Participants studied six members from each of eight taxonomic categories and then practiced recalling three of the six members from four of the eight categories using category-stem cues. This retrieval practice suppressed the detection of non-practiced members of the practiced categories during the PM task with non-focal cues (Experiment 1) but not with focal cues (Experiment 2). The results suggest that recall of certain items inhibits the function of the others as PM cues, but only if the PM task does not largely share its processing with the ongoing task.

CAMS as a tool for human factors research in spaceflight

NASA Astrophysics Data System (ADS)

Sauer, Juergen

2004-01-01

The paper reviews a number of research studies that were carried out with a PC-based task environment called Cabin Air Management System (CAMS) simulating the operation of a spacecraft's life support system. As CAMS was a multiple task environment, it allowed the measurement of performance at different levels. Four task components of different priority were embedded in the task environment: diagnosis and repair of system faults, maintaining atmospheric parameters in a safe state, acknowledgement of system alarms (reaction time), and keeping a record of critical system resources (prospective memory). Furthermore, the task environment permitted the examination of different task management strategies and changes in crew member state (fatigue, anxiety, mental effort). A major goal of the research programme was to examine how crew members adapted to various forms of sub-optimal working conditions, such as isolation and confinement, sleep deprivation and noise. None of the studies provided evidence for decrements in primary task performance. However, the results showed a number of adaptive responses of crew members to adjust to the different sub-optimal working conditions. There was evidence for adjustments in information sampling strategies (usually reductions in sampling frequency) as a result of unfavourable working conditions. The results also showed selected decrements in secondary task performance. Prospective memory seemed to be somewhat more vulnerable to sub-optimal working conditions than performance on the reaction time task. Finally, suggestions are made for future research with the CAMS environment.

The operating room (OR) remains the main teaching venue for surgical trainees. The OR is considered a pure-discovery learning environment; the downsides of this can be putatively overcome when faculty and trainee arrive at a shared understanding of learning. This study aimed to better understand preoperative learning goals to identify areas of commonalities and potential barrier to intraoperative teaching. Brief, structured preoperative interviews were conducted outside the OR with the resident and faculty member who were scheduled to operate together. Answers were analyzed and grouped using grounded theory. Twenty-seven resident-faculty pairs were interviewed. Nine residents (33.3%) were junior (PGY 1 and 2) and 18 (66.7%) were senior (PGY 3 through 5). Learning goal categories that emerged from the response analysis were anatomy, basic and advanced surgical skills, general and specific procedural tasks, technical autonomy, and pre-, intra-, and postoperative considerations. Residents articulated fewer learning goals than faculty (1.5 versus 2.4; P = 0.024). The most frequently identified learning goal by both groups was one classifiable under general procedural tasks; the greatest divergence was seen regarding perioperative considerations, which were identified frequently by faculty members but rarely by residents. Faculty articulate significantly more learning goals for the residents they will operate with than residents articulate for themselves. Our data suggest that residents and faculty align on some learning goals for the OR but residents tend to be more limited, focusing predominantly on technical aspects of the operation. Faculty members tend to hold a broader view of the learning potential of the OR. These discrepancies may present barriers to effective intraoperative teaching. Copyright © 2011 Elsevier Inc.

1982-01-01

The objective of this training tool in group dynamics is to have the participants' experience and identify barriers to the accomplishment of group tasks and to give the trainer an opportunity to observe interaction within a particular group of participants. This exercise works best for groups which have been together long enough to establish mutual trust. There can be 10 to 20 participants and one should allow 1 1/2 to 2 hours. The materials required are pieces of paper to represent currency, paper for computation and notes, and writing implements. Details of the procedure are given. The material was prepared by INTRAH staff members. Other materials include how to use tracing techniques to create visual aids, how to evaluate teaching and how to create a family health case study.

Skewed task conflicts in teams: What happens when a few members see more conflict than the rest?

PubMed

Sinha, Ruchi; Janardhanan, Niranjan S; Greer, Lindred L; Conlon, Donald E; Edwards, Jeffery R

2016-07-01

Task conflict has been the subject of a long-standing debate in the literature-when does task conflict help or hurt team performance? We propose that this debate can be resolved by taking a more precise view of how task conflicts are perceived in teams. Specifically, we propose that in teams, when a few team members perceive a high level of task disagreement while a majority of others perceive low levels of task disagreement-that is, there is positively skewed task conflict, task conflict is most likely to live up to its purported benefits for team performance. In our first study of student teams engaged in a business decision game, we find support for the positive relationship between skewed task conflict and team performance. In our second field study of teams in a financial corporation, we find that the relationship between positively skewed task conflict and supervisor ratings of team performance is mediated by reflective communication within the team.

Contingent interaction during work and play tasks for mothers with multiple sclerosis and their daughters.

PubMed

Crist, P

1993-02-01

Occupational therapy has focused on activity as a catalyst for understanding human roles and interactions, regardless of whether disability or chronic illness is present. Parenting is an important interactional activity accompanied by specific role expectations. This investigation examined the interaction patterns of mothers with multiple sclerosis and their daughters. Thirty-one mothers with multiple sclerosis and their daughters aged 8 to 12 years were compared with 34 mothers without disabilities and their daughters aged 8 to 12 years. Videotaped mother-daughter interactions during a work task and a play task were scored by two raters for 11 different behaviors. These behaviors were collapsed into three behavioral composites--receptiveness, directiveness, and dissuasiveness--for statistical analysis. Statistical analysis revealed no significant differences between the two groups on the behavioral composites for either mothers or their daughters. The two tasks stimulated a different pattern of mother-daughter interactions. For both members of the dyad, interactions during the work task were more directive and less dissuasive than those in the play task. The clinical implication of this finding indicates the importance of understanding the influence of the task selected when observing interaction. Because of recent social and legal changes, understanding parenting and chronic illness is critical.

This report summarizes the results of a five-month LDRD late start project which explored the potential of enabling technology to improve the performance of small groups. The purpose was to investigate and develop new methods to assist groups working in high consequence, high stress, ambiguous and time critical situations, especially those for which it is impractical to adequately train or prepare. A testbed was constructed for exploratory analysis of a small group engaged in tasks with high cognitive and communication performance requirements. The system consisted of five computer stations, four with special devices equipped to collect physiologic, somatic, audio andmore » video data. Test subjects were recruited and engaged in a cooperative video game. Each team member was provided with a sensor array for physiologic and somatic data collection while playing the video game. We explored the potential for real-time signal analysis to provide information that enables emergent and desirable group behavior and improved task performance. The data collected in this study included audio, video, game scores, physiological, somatic, keystroke, and mouse movement data. The use of self-organizing maps (SOMs) was explored to search for emergent trends in the physiological data as it correlated with the video, audio and game scores. This exploration resulted in the development of two approaches for analysis, to be used concurrently, an individual SOM and a group SOM. The individual SOM was trained using the unique data of each person, and was used to monitor the effectiveness and stress level of each member of the group. The group SOM was trained using the data of the entire group, and was used to monitor the group effectiveness and dynamics. Results suggested that both types of SOMs were required to adequately track evolutions and shifts in group effectiveness. Four subjects were used in the data collection and development of these tools. This report documents a proof of concept study, and its observations are preliminary. Its main purpose is to demonstrate the potential for the tools developed here to improve the effectiveness of groups, and to suggest possible hypotheses for future exploration.« less

Calculus detection calibration among dental hygiene faculty members utilizing dental endoscopy: a pilot study.

2015-02-01

Dental and dental hygiene faculty members often do not provide consistent instruction in the clinical environment, especially in tasks requiring clinical judgment. From previous efforts to calibrate faculty members in calculus detection using typodonts, researchers have suggested using human subjects and emerging technology to improve consistency in clinical instruction. The purpose of this pilot study was to determine if a dental endoscopy-assisted training program would improve intra- and interrater reliability of dental hygiene faculty members in calculus detection. Training included an ODU 11/12 explorer, typodonts, and dental endoscopy. A convenience sample of six participants was recruited from the dental hygiene faculty at a California community college, and a two-group randomized experimental design was utilized. Intra- and interrater reliability was measured before and after calibration training. Pretest and posttest Kappa averages of all participants were compared using repeated measures (split-plot) ANOVA to determine the effectiveness of the calibration training on intra- and interrater reliability. The results showed that both kinds of reliability significantly improved for all participants and the training group improved significantly in interrater reliability from pretest to posttest. Calibration training was beneficial to these dental hygiene faculty members, especially those beginning with less than full agreement. This study suggests that calculus detection calibration training utilizing dental endoscopy can effectively improve interrater reliability of dental and dental hygiene clinical educators. Future studies should include human subjects, involve more participants at multiple locations, and determine whether improved rater reliability can be sustained over time.

Attitudes of dental students regarding the provision of treatment tend to be dentist-centered; however, facilitating mixed student group formation could change such perceptions. The aim of this study was to investigate the perceived scope of practice of dental and dental hygiene students and whether their perceptions of task distribution between dentists and dental hygienists would change following an educational intervention consisting of feedback, intergroup comparison, and competition between mixed-group teams. The study employed a pretest-posttest single group design. Third-year dental students and second-year dental hygiene students at a university in The Netherlands were randomly assigned to intraprofessional teams (four or five members) and received team-based performance feedback and comparison. The intervention was finalized with an award ceremony for the best intraprofessional team. Before and after the intervention, students completed a questionnaire measuring their perceived distribution of ten tasks between dentists and dental hygienists. A total of 38 dental students and 32 dental hygiene students participated in the intervention-all 70 of those eligible. Questionnaires were completed by a total 88.4% (n=61) of the participants: 34 dental (89.5%) and 27 dental hygiene students (84.4%). Dental and dental hygiene students had similar perceptions regarding teeth cleaning (prophylaxis) (p=0.372, p=0.404) and, after the intervention, preventive tasks (p=0.078). Following the intervention, dental students considered four out of ten tasks as less dentist-centered: radiograph for periodontal diagnosis (p=0.003), local anesthesia (p=0.037), teeth cleaning (p=0.037), and periodontal treatment (p=0.045). Dental hygiene students perceived one task as being less dentist-centered after the intervention: radiograph for cariologic diagnosis (p=0.041). This study found that these dental and dental hygiene students had different opinions regarding the scope of practice for dentistry and dental hygiene. The number of redistributed tasks after the intervention was especially substantial among the dental students, although the amount of change per task was minimal. Half of all tasks were perceived as less dentist-centered as a result of the intervention.

Sugar ingestion and dichotic listening: Increased perceptual capacity is more than motivation.

PubMed

Scheel, Matthew H; Ambrose, Aimee L

2014-01-01

Participants ingested a sugar drink or a sugar-free drink and then engaged in a pair of dichotic listening tasks. Tasks presented category labels then played a series of word pairs, one in the left ear and one in the right. Participants attempted to identify pairs containing a target category member. Target category words were homonyms. For example, arms appeared as a target in the "body parts" category. Nontargets that played along with targets were related to a category-appropriate version of the target (e.g., sleeves), a category-inappropriate version (e.g., weapons), or were unrelated to either version of the target (e.g., plant). Hence, an effect of nontarget type on number of targets missed was evidence that participants processed nontargets for meaning. In the divided attention task, participants monitored both ears. In the focused attention task, participants monitored the left ear. Half the participants in each group had the divided attention task before the focused attention task; the other half had the focused attention task before the divided attention task. We set task lengths to about 12 min so working on the first task would give sufficient time for metabolizing sugar from the drink before the start of the second task. Nontarget word type significantly affected targets missed in both tasks. Drink type affected performance in the divided attention task only after sufficient time for converting sugar into blood glucose. The result supports an energy model for the effect of sugar ingestion on perceptual tasks rather than a motivational model.

We tend to think that everyone deserves an equal say in a debate. This seemingly innocuous assumption can be damaging when we make decisions together as part of a group. To make optimal decisions, group members should weight their differing opinions according to how competent they are relative to one another; whenever they differ in competence, an equal weighting is suboptimal. Here, we asked how people deal with individual differences in competence in the context of a collective perceptual decision-making task. We developed a metric for estimating how participants weight their partner’s opinion relative to their own and compared this weighting to an optimal benchmark. Replicated across three countries (Denmark, Iran, and China), we show that participants assigned nearly equal weights to each other’s opinions regardless of true differences in their competence—even when informed by explicit feedback about their competence gap or under monetary incentives to maximize collective accuracy. This equality bias, whereby people behave as if they are as good or as bad as their partner, is particularly costly for a group when a competence gap separates its members. PMID:25775532

2012-08-01

There is a need to train and evaluate a wide variety of nontechnical surgical skills. The goal of this project was to develop and evaluate a decision-based simulation to assess team skills. The decision-based exercise used our previously validated Laparoscopic Ventral Hernia simulator and a newly developed team evaluation survey. Five teams of 3 surgical residents (N = 15) were tasked with repairing a 10 × 10-cm right upper quadrant hernia. During the simulation, independent observers (N = 6) completed a 6-item survey assessing: (1) work quality; (2) communication; and (3) team effectiveness. After the simulation, team members self-rated their performance by using the same survey. Survey reliability revealed a Cronbach's alpha of r = .811. Significant differences were found when we compared team members' (T) and observers' (O) ratings for communication (T = 4.33/5.00 vs O = 3.00/5.00, P < .01) and work quality (T = 4.33/5.00 vs O = 3.33/5.00, P < .05). The team with the greatest survey ratings was the only group to successfully complete the task. The team evaluation survey had good reliability and correlated with task performance on the simulator. Our current and previous work provides strong evidence that nontechnical and team related skills can be assessed without simulating a crisis situation. Copyright © 2012 Mosby, Inc.

Community coalitions have proliferated as a means of addressing a range of complex community problems. Such coalitions often consist of a small paid staff and volunteer members. The present study examines one likely contributor to coalition effectiveness: the degree of agreement on role expectations between paid staff and volunteer members. Role confusion occurs when paid staff and volunteers differ in their expectations of who is responsible for accomplishing specific tasks. Staff and volunteer members from 69 randomly selected Drug Free Coalitions in the United States as well as 21 Drug Free Coalitions in Connecticut were asked to respond to an online survey asking about 37 specific coalition tasks critical for effective coalition functioning and the degree to which paid staff and/or voluntary members should be responsible for accomplishing each. Our final sample consisted of 476 individuals from 35 coalitions. Using coalitions as the unit of analysis, we found significant differences between paid staff and volunteer coalition members on nine tasks reflecting four domains: meeting leadership and participation, (2) planning and implementation leadership, (3) publicity/media relations, and (4) logistical functions. Implications of these differences and ways that evaluators could help coalitions deal with differing role expectations were discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Marine and freshwater toxins.

PubMed

Hungerford, James M

2006-01-01

In a very busy and exciting year, 2005 included First Action approval of a much needed official method for paralytic shellfish toxins and multiple international toxin symposia highlighted by groundbreaking research. These are the first-year milestones and activities of the Marine and Freshwater Toxins Task Force and Analytical Community. Inaugurated in 2004 and described in detail in last year's General Referee Report (1) this international toxins group has grown to 150 members from many regions and countries. Perhaps most important they are now making important and global contributions to food safety and to providing alternatives to animal-based assays. Official Method 2005.06 was first approved in late 2004 by the Task Force and subsequently Official First Action in 2005 (2) by the Methods Committee on Natural Toxins and Food Allergens and the Official Methods Board. This nonproprietary method (3) is a precolumn oxidation, liquid chromatographic method that makes good use of fluorescence detection to provide high sensitivity detection of the saxitoxins. It has also proven to be rugged enough for regulatory use and the highest level of validation. As pointed out in the report of method principle investigator and Study Director James Lawrence, approval of 2005.06 now provides the first official alternative to the mouse bioassay after many decades of shellfish monitoring. This past year in April 2005 the group also held their first international conference, "Marine and Freshwater Toxins Analysis: Ist Joint Symposium and AOAC Task Force Meeting," in Baiona, Spain. The 4-day conference consisted of research and stakeholder presentations and symposium-integrated subgroup sessions on ciguatoxins, saxitoxin assays and liquid chromatography (LC) methods for saxitoxins and domoic acids, okadaiates and azaspiracids, and yessotoxins. Many of these subgroups were recently formed in 2005 and are working towards their goals of producing officially validated analytical methods. (Abstracts from the Baiona 2005 meeting cited in this report can be found in the online version of the conference abstract book in the Files and Folders section of the Marine and Freshwater Toxins online community at www.aoac.org.) An active topic for discussion in Baiona and subsequent Task Force activities was the expert consultation for Codex which met in Oslo, Norway in 2004 (previously described and cited in last year's GR report, ref 1). The consultation group's executive summary report (http://www.fao.org/es/ESN/food/risk_biotoxin en.stm) describes suggested changes in action levels as well as methods, method validation, and other issues. September 2005 saw the AOAC Task Force efforts further supported by another symposium, "Marine and Freshwater Toxins: Quality Methods for Food Safety and International Trade," at the AOAC INTERNATIONAL Annual Conference in Orlando, Florida. The multidisciplinary talks at this full day symposium ranged from ciguatoxins to cyanobacterial toxins, and spanned toxicology, biochemistry, molecular biology and analytical chemistry. Again, the symposium preceded Task Force meetings. Toxin subgroups, including a new group on cyanobacterial toxins, met for engaging and productive subgroup discussions. All of these activities were preceded by a Wiley Award symposium for Task Force member Mike Quilliam of NRC Canada. These talks, presented at a half-day symposium on the first day of the Annual Meeting, focused on Quilliam's work with LC tandem mass spectrometry (LC/MS/MS) and certified reference standards and materials, and included related presentations by some of his many research collaborators. To maintain flow and continuity between symposia and between Task Force meetings, the group now uses new electronic discussion forums. Individual subgroup areas, under the Marine and Freshwater Toxins Task Force, comprise this online community. First introduced by AOAC INTERNATIONAL in early 2005, these new resources are being used to distribute information and to supplement the in-person subgroup meetings and electronic mail in the group's validation efforts.

An Onboard ISS Virtual Reality Trainer

NASA Technical Reports Server (NTRS)

Miralles, Evelyn

2013-01-01

Prior to the retirement of the Space Shuttle, many exterior repairs on the International Space Station (ISS) were carried out by shuttle astronauts, trained on the ground and flown to the Station to perform these specific repairs. With the retirement of the shuttle, this is no longer an available option. As such, the need for ISS crew members to review scenarios while on flight, either for tasks they already trained for on the ground or for contingency operations has become a very critical issue. NASA astronauts prepare for Extra-Vehicular Activities (EVA) or Spacewalks through numerous training media, such as: self-study, part task training, underwater training in the Neutral Buoyancy Laboratory (NBL), hands-on hardware reviews and training at the Virtual Reality Laboratory (VRLab). In many situations, the time between the last session of a training and an EVA task might be 6 to 8 months. EVA tasks are critical for a mission and as time passes the crew members may lose proficiency on previously trained tasks and their options to refresh or learn a new skill while on flight are limited to reading training materials and watching videos. In addition, there is an increased need for unplanned contingency repairs to fix problems arising as the Station ages. In order to help the ISS crew members maintain EVA proficiency or train for contingency repairs during their mission, the Johnson Space Center's VRLab designed an immersive ISS Virtual Reality Trainer (VRT). The VRT incorporates a unique optical system that makes use of the already successful Dynamic On-board Ubiquitous Graphics (DOUG) software to assist crew members with procedure reviews and contingency EVAs while on board the Station. The need to train and re-train crew members for EVAs and contingency scenarios is crucial and extremely demanding. ISS crew members are now asked to perform EVA tasks for which they have not been trained and potentially have never seen before. The Virtual Reality Trainer (VRT) provides an immersive 3D environment similar to the one experienced at the VRLab crew training facility at the NASA Johnson Space Center. VRT bridges the gap by allowing crew members to experience an interactive, 3D environment to reinforce skills already learned and to explore new work sites and repair procedures outside the Station.

Dynamics of Cooperation in a Task Completion Social Dilemma

PubMed Central

Passino, Kevin M.

2017-01-01

We study the situation where the members of a community have the choice to participate in the completion of a common task. The process of completing the task involves only costs and no benefits to the individuals that participate in this process. However, completing the task results in changes that significantly benefit the community and that exceed the participation efforts. A task completion social dilemma arises when the short-term participation costs dissipate any interest in the community members to contribute to the task completion process and therefore to obtain the benefits that result from completing the task. In this work, we model the task completion problem using a dynamical system that characterizes the participation dynamics in the community and the task completion process. We show how this model naturally allows for the incorporation of several mechanisms that facilitate the emergence of cooperation and that have been studied in previous research on social dilemmas, including communication across a network, and indirect reciprocity through relative reputation. We provide mathematical analyses and computer simulations to study the qualitative properties of the participation dynamics in the community for different scenarios. PMID:28125721

Can Simple Transmission Chains Foster Collective Intelligence in Binary-Choice Tasks?

In many social systems, groups of individuals can find remarkably efficient solutions to complex cognitive problems, sometimes even outperforming a single expert. The success of the group, however, crucially depends on how the judgments of the group members are aggregated to produce the collective answer. A large variety of such aggregation methods have been described in the literature, such as averaging the independent judgments, relying on the majority or setting up a group discussion. In the present work, we introduce a novel approach for aggregating judgments-the transmission chain-which has not yet been consistently evaluated in the context of collective intelligence. In a transmission chain, all group members have access to a unique collective solution and can improve it sequentially. Over repeated improvements, the collective solution that emerges reflects the judgments of every group members. We address the question of whether such a transmission chain can foster collective intelligence for binary-choice problems. In a series of numerical simulations, we explore the impact of various factors on the performance of the transmission chain, such as the group size, the model parameters, and the structure of the population. The performance of this method is compared to those of the majority rule and the confidence-weighted majority. Finally, we rely on two existing datasets of individuals performing a series of binary decisions to evaluate the expected performances of the three methods empirically. We find that the parameter space where the transmission chain has the best performance rarely appears in real datasets. We conclude that the transmission chain is best suited for other types of problems, such as those that have cumulative properties.

An Onboard ISS Virtual Reality Trainer

NASA Technical Reports Server (NTRS)

Miralles, Evelyn

2013-01-01

Prior to the retirement of the Space Shuttle, many exterior repairs on the International Space Station (ISS) were carried out by shuttle astronauts, trained on the ground and flown to the station to perform these repairs. After the retirement of the shuttle, this is no longer an available option. As such, the need for the ISS crew members to review scenarios while on flight, either for tasks they already trained or for contingency operations has become a very critical subject. In many situations, the time between the last session of Neutral Buoyancy Laboratory (NBL) training and an Extravehicular Activity (EVA) task might be 6 to 8 months. In order to help with training for contingency repairs and to maintain EVA proficiency while on flight, the Johnson Space Center Virtual Reality Lab (VRLab) designed an onboard immersive ISS Virtual Reality Trainer (VRT), incorporating a unique optical system and making use of the already successful Dynamic Onboard Ubiquitous Graphical (DOUG) graphics software, to assist crew members with current procedures and contingency EVAs while on flight. The VRT provides an immersive environment similar to the one experienced at the VRLab crew training facility at NASA Johnson Space Center. EVA tasks are critical for a mission since as time passes the crew members may lose proficiency on previously trained tasks. In addition, there is an increased need for unplanned contingency repairs to fix problems arising as the ISS ages. The need to train and re-train crew members for EVAs and contingency scenarios is crucial and extremely demanding. ISS crew members are now asked to perform EVA tasks for which they have not been trained and potentially have never seen before.

Group boundary permeability moderates the effect of a dependency meta-stereotype on help-seeking behaviour.

PubMed

Zhang, Lange; Kou, Yu; Zhao, Yunlong; Fu, Xinyuan

2016-08-01

Previous studies have found that when low-status group members are aware that their in-group is stereotyped as dependent by a specific out-group (i.e. a dependency meta-stereotype is salient), they are reluctant to seek help from the high-status out-group to avoid confirming the negative meta-stereotype. However, it is unclear whether low-status group members would seek more help in the context of a salient dependency meta-stereotype when there is low (vs. high) group boundary permeability. Therefore, we conducted two experiments to examine the moderating effect of permeability on meta-stereotype confirmation with a real group. In study 1, we manipulated the salience of the dependency meta-stereotype, measured participants' perceived permeability and examined their help-seeking behaviour in a real-world task. Participants who perceived low permeability sought more help when the meta-stereotype was salient (vs. not salient), whereas participants who perceived high permeability sought the same amount of help across conditions. In study 2, we manipulated the permeability levels and measured the dependency meta-stereotype. Participants who endorsed a high-dependency meta-stereotype sought more help than participants who endorsed a low-dependency meta-stereotype; this effect was particularly strong in the low-permeability condition. The implications of these results for social mobility and intergroup helping are discussed. © 2015 International Union of Psychological Science.

Conflicting social motives in negotiating groups.

Weingart, Laurie R; Brett, Jeanne M; Olekalns, Mara; Smith, Philip L

2007-12-01

Negotiators' social motives (cooperative vs. individualistic) influence their strategic behaviors. In this study, the authors used multilevel modeling and analyses of strategy sequences to test hypotheses regarding how negotiators' social motives and the composition of the group influence group members' negotiation strategies. Four-person groups negotiating a 5-issue mixed-motive decision-making task were videotaped, and the tapes were transcribed and coded. Group composition included 2 homogeneous conditions (all cooperators and all individualists) and 3 heterogeneous conditions (3 cooperators and 1 individualist, 2 cooperators and 2 individualists, 1 cooperator and 3 individualists). Results showed that cooperative negotiators adjusted their use of integrative and distributive strategies in response to the social-motive composition of the group, but individualistic negotiators did not. Results from analyses of strategy sequences showed that cooperators responded more systematically to others' behaviors than did individualists. They also redirected the negotiation depending on group composition. (c) 2007 APA, all rights reserved.

Multi-team dynamics and distributed expertise in imission operations.

PubMed

Caldwell, Barrett S

2005-06-01

The evolution of space exploration has brought an increased awareness of the social and socio-technical issues associated with team performance and task coordination, both for the onboard astronauts and in mission control. Spaceflight operations create a unique environment in which to address classic group dynamics topics including communication, group process, knowledge development and sharing, and time-critical task performance. Mission operations in the early years of the 21st century have developed into a set of complex, multi-team task settings incorporating multiple mission control teams and flight crews interacting in novel ways. These more complex operational settings help highlight the emergence of a new paradigm of distributed supervisory coordination, and the need to consider multiple dimensions of expertise being supported and exchanged among team members. The creation of new mission profiles with very long-duration time scales (months, rather than days) for the International Space Station, as well as planned exploration missions to the Moon and Mars, emphasize fundamental distinctions from the 40 yr from Mercury to the Space Shuttle. Issues in distributed expertise and information flow in mission control settings from two related perspectives are described. A general conceptual view of knowledge sharing and task synchronization is presented within the context of the mission control environment. This conceptual presentation is supplemented by analysis of quasi-experimental data collected from actual flight controllers at NASA-Johnson Space Center, Houston, TX.

Effect of hierarchy legitimacy on low status group members' attributions for ingroup and outgroup failures.

PubMed

Beatson, Ruth M; Halloran, Michael J

2015-04-01

Previous research has shown that people have a tendency to explain successes and failures in ways that favor their ingroups relative to outgroups. However, there has been a dearth of research examining whether social-contextual factors such as group status and hierarchy legitimacy moderate such intergroup attributions. Participants in this study were assigned to a low status group, and perceived hierarchy legitimacy was then experimentally manipulated; the extent to which ingroup versus outgroup failures were attributed to several causes was measured. When low status was considered illegitimate, ingroup failure was attributed to external causes (task difficulty, bad luck) more so than outgroup failure. Implications and directions for future research examining consequences and mediating processes are discussed.

Implementing an effective organization and governance structure for a radiology practice.

PubMed

Muroff, Lawrence R

2004-01-01

Radiology practices that are well organized and effectively governed have a competitive advantage. Decisions are made rapidly, actions are taken decisively and in accordance with established policy, and each group member has a responsibility for practice building. Such groups are perceived by their peers, hospital administration, and community business leaders to be both formidable and effective. This paper details the mechanisms that facilitate planning for and implementing an efficient practice organization and governance structure. The tasks of group leaders are defined, as are the committees necessary for appropriate action. The integral roles of a mission statement and a business plan are discussed. Practices adopting the suggested organizational structure will be best positioned to survive in both good times and bad.

Psychosocial workload and stress in the workers’ representative

2012-01-01

Background Using a data set of works councils of trade union IG Metal, this paper investigates psychosocial stress and strain on this specific group in comparison to employees working in administration in general (leadership and non-leadership-role) and a national reference value. Methods For assessing psychosocial work factors on works councils within the sector represented by the trade union IG Metal in Germany, a research by using the German standard version of COPSOQ (Copenhagen Psychosocial Questionnaire) was performed. The instrument includes 87 single items forming 25 aspects of strain and stress. Results from the study group of works councils were compared to those from employees working in administration and to the general population mean (COPSOQ database). Statistical analysis included t-tests, analysis of variance and multiple comparisons of means. To be significant in terms of statistics, p<0.05 (two-tailed) and a minimum deviation of 5 or more points between groups′ mean values identify the relevant values. Results All in all, 309 works councils from a national survey of the German chemical and metalworking industries took part in the study. 113 were full-time works council members (exempted from the duty to perform their regular work), 196 were voluntary members (acting as employee representatives on an honorary basis alongside their normal duties). Comparison between works councils and employees working in administration (leadership roles (N=1810) and non-leadership roles (N=2970)) and for employees in general (N=35.000) showed unfavourable values for works councils for most scales. Significantly higher values indicating higher strain and stress were found for the scales: emotional demands, work-privacy conflict, role conflicts, mobbing, cognitive stress symptoms and burnout. Unfavourable results were obtained for the aspects: quality of leadership, social support, sense of community and general health. Favourable findings were found on the scales: influence at work, quantity of social relations and the partly positive values for quantitative demands and commitment to the workplace. Conclusion Compared to the reference groups, works council members perceive the psychosocial demands of working life as more exhausting for the majority of aspects. This allows several conclusions. One reason may be the extended tasks employee representatives face, an other may be that the education of most works council members does not seem appropriate to the high demands of their managerial and executive tasks.

Ineffective coping may lead to impaired job performance and burnout, with adverse consequences to staff well-being and patient outcomes. We examined the relationship between coping styles and burnout in emergency physicians, nurses and support staff at seven small, medium and large emergency departments (ED) in a Canadian health region (population 500,000). Linear regression with the Coping Inventory for Stressful Situations (CISS) and Maslach Burnout Inventory (MBI) was used to evaluate the effect of coping style on levels of burnout in a cross-sectional survey of 616 ED staff members. CISS measures coping style in three categories: task-oriented, emotion-oriented and avoidance-oriented coping; MBI, in use for 30 years, assesses the level of burnout in healthcare workers. Task-oriented coping was associated with decreased risk of burnout, while emotion-oriented coping was associated with increased risk of burnout. Specific coping styles are associated with varied risk of burnout in ED staff across several different types of hospitals in a regional network. Coping style intervention may reduce burnout, while leading to improvement in staff well-being and patient outcomes. Further studies should focus on building and sustaining task-oriented coping, along with alternatives to emotion-oriented coping. Published by the BMJ Publishing Group Limited.

Numerous accrediting organizations are calling for competency-based medical education that would help define specific specialties and serve as a foundation for ongoing assessment throughout a practitioner's career. Pulmonary Medicine and Critical Care Medicine are two distinct subspecialties, yet many individual physicians have expertise in both because of overlapping content. Establishing specific competencies for these subspecialties identifies educational goals for trainees and guides practitioners through their lifelong learning. To define specific competencies for graduates of fellowships in Pulmonary Medicine and Internal Medicine-based Critical Care. A Task Force composed of representatives from key stakeholder societies convened to identify and define specific competencies for both disciplines. Beginning with a detailed list of existing competencies from diverse sources, the Task Force categorized each item into one of six core competency headings. Each individual item was reviewed by committee members individually, in group meetings, and conference calls. Nominal group methods were used for most items to retain the views and opinions of the minority perspective. Controversial items underwent additional whole group discussions with iterative modified-Delphi techniques. Consensus was ultimately determined by a simple majority vote. The Task Force identified and defined 327 specific competencies for Internal Medicine-based Critical Care and 276 for Pulmonary Medicine, each with a designation as either: (1) relevant, but competency is not essential or (2) competency essential to the specialty. Specific competencies in Pulmonary and Critical Care Medicine can be identified and defined using a multisociety collaborative approach. These recommendations serve as a starting point and set the stage for future modification to facilitate maximum quality of care as the specialties evolve.

A task force for the American Society for Surgery of the Hand (ASSH) recently investigated the practice patterns, board certification, subspecialty certification status, and ASSH membership of hand surgeons after completion of fellowship training. A total of 37% of the fellowship graduates from 2000 to 2006 had not attained subspecialty certification for a variety of reasons. A smaller group of fellowship graduates obtained the subspecialty certification but had not become Active Members of the ASSH. Efforts to strengthen the hand surgeon community and best serve our patients should focus on evolving patterns in post fellowship choices that reflect practice type choices and generational changes.

A proposed model for small-world structural organization of mission teams and tasks in order to optimize efficiency and minimize costs

NASA Astrophysics Data System (ADS)

Ribeiro, André S.; Almeida, Miguel

2003-11-01

We propose a model of structural organization and intercommunication between all elements of every team involved in the development of a space probe to improve efficiency. Such structure is built to minimize path between any two elements, allowing fast information flow in the structure. Structures are usually very clustered inside each task team but only the heads of departments, or occasional meetings, usually assure the links between team elements. This is responsible for a lack of information exchange between staff members of each team. We propose the establishment of permanent small working groups of staff elements from different teams, in a random but permanent basis. The elements chosen for such connections establishment can be chosen in a temporary basis, but the connections must exist permanently because only with permanent connections can information flow when needed. A few of such random connections between staff members will diminish the average path length, between any two elements of any team, for information exchange. A small world structure will emerge with low internal energy costs, which is the structure used by biological neuronal systems.

Distortions in autobiographical memory have been implicated in major depressive disorder (MDD). Those with MDD demonstrate a 'depressogenic' autobiographical life structure. Research has not examined how culture influences this process. We investigated whether Malay individuals (members of an interdependent culture) with MDD demonstrated a 'depressogenic' autobiographical life structure similar to that of British individuals (members of an independent culture) with MDD. A 2 (Culture; Malay, British) × 2 (Mood; depressed, control) cross-sectional design using a card sort task and self-report measures was used. Malay individuals with MDD or no history of MDD completed the life-structure card-sorting task, which provided a novel method for investigating organizational structure of the life narrative. These data were compared to previously collected data in which British individuals with MDD or without MDD had completed the same task within the same experimental protocol. Pan-culturally those with MDD had greater negativity (i.e., used more negative attributes), negative redundancy (i.e., used the same negative attributes repeatedly across life chapters) and negative emodiversity (i.e., had greater variety and relative abundance of negative attributes), and reduced positive redundancy (i.e., used the same positive attributes repeatedly across chapters) in their structuring relative to controls. While the British MDD group had greater compartmentalization (i.e., the negative and positive attributes were clustered separately across different chapters) than British controls, the Malay MDD group had lower levels of compartmentalization than Malay controls. The findings suggest culture may shape aspects of the autobiographical life structure in MDD. The majority of the literature investigating depression pertains to individuals from European Western cultures, despite recognition that depression ranks as one of the most debilitating diseases worldwide. This raises questions as to whether current depression models and interventions can be applied universally or whether they are limited to European Western groups. The current study found that pan-culturally those with MDD had similar structuring of their life story relative to controls. However, there were some cultural differences that need to be considered (e.g., Malay individuals provided less detailed, less elaborate and less emotionally diverse life stories and while the British MDD group had greater compartmentalization than British controls, the Malay MDD group had lower levels of compartmentalization than Malay controls). Limitations of the study included group differences in gender and mood at the time of testing. Cultural differences in the number of attributes used may have influenced findings. Only the Malay group completed the individualism-collectivism measure. © 2018 The British Psychological Society.

2017-01-01

Abstract Social groups aid human beings in several ways, ranging from the fulfillment of complex social and personal needs to the promotion of survival. Despite the importance of group affiliation to humans, there remains considerable variation in group preferences across development. In the current study, children and adolescents completed an explicit evaluation task of in-group and out-group members during functional neuroimaging. We found that participants displayed age-related increases in bilateral amygdala, fusiform gyrus and orbitofrontal cortex (OFC) activation when viewing in-group relative to out-group faces. Moreover, we found an indirect effect of age on in-group favoritism via brain activation in the amygdala, fusiform and OFC. Finally, with age, youth showed greater functional coupling between the amygdala and several neural regions when viewing in-group relative to out-group peers, suggesting a role of the amygdala in directing attention to motivationally relevant cues. Our findings suggest that the motivational significance and processing of group membership undergoes important changes across development. PMID:27633395

A new model for recognizing and rewarding the educational accomplishments of surgery faculty.

1999-12-01

Faculty members' educational endeavors have generally not received adequate recognition. The Association for Surgical Education in 1993 established a task force to determine the magnitude of this problem and to create a model to address the challenges and opportunities identified. To obtain baseline information, the task force reviewed information from national sources and the literature on recognizing and rewarding faculty members for educational accomplishments. The group also developed and mailed to surgery departments at all U.S. and Canadian medical schools a questionnaire asking about the educational endeavors of the surgery faculty and their recognition for such activities. The response rate after two mailings was only 56%, but the responses reaffirmed the inadequacy of systems for rewarding and recognizing surgeon-teachers and surgeon-educators, and confirmed that the distinction between the roles of teacher and educator was rarely made. The task force created a four-tier hierarchical model based on the designations teacher, master teacher, educator, and master educator as a framework to offer appropriate recognition and rewards to the faculty, and endorsed a broad definition of educational scholarship. Criteria for various levels of achievement, ways to demonstrate and document educational contributions, appropriate support and recognition, and suggested faculty ranks were defined for these levels. The task force recommended that each surgery department have within its faculty ranks a cadre of trained teachers, a few master teachers, and at least one educator. Departments with a major commitment to education should consider supporting a master educator to serve as a resource not only for the department but also for the department's medical school and other medical schools. Although this model was created for surgery departments, it is generalizable to other disciplines.

Phenomenological theory of collective decision-making

Zafeiris, Anna; Koman, Zsombor; Mones, Enys; Vicsek, Tamás

2017-08-01

An essential task of groups is to provide efficient solutions for the complex problems they face. Indeed, considerable efforts have been devoted to the question of collective decision-making related to problems involving a single dominant feature. Here we introduce a quantitative formalism for finding the optimal distribution of the group members' competences in the more typical case when the underlying problem is complex, i.e., multidimensional. Thus, we consider teams that are aiming at obtaining the best possible answer to a problem having a number of independent sub-problems. Our approach is based on a generic scheme for the process of evaluating the proposed solutions (i.e., negotiation). We demonstrate that the best performing groups have at least one specialist for each sub-problem - but a far less intuitive result is that finding the optimal solution by the interacting group members requires that the specialists also have some insight into the sub-problems beyond their unique field(s). We present empirical results obtained by using a large-scale database of citations being in good agreement with the above theory. The framework we have developed can easily be adapted to a variety of realistic situations since taking into account the weights of the sub-problems, the opinions or the relations of the group is straightforward. Consequently, our method can be used in several contexts, especially when the optimal composition of a group of decision-makers is designed.

Family-led rehabilitation after stroke in India (ATTEND): a randomised controlled trial.

PubMed

2017-08-05

Most people with stroke in India have no access to organised rehabilitation services. The effectiveness of training family members to provide stroke rehabilitation is uncertain. Our primary objective was to determine whether family-led stroke rehabilitation, initiated in hospital and continued at home, would be superior to usual care in a low-resource setting. The Family-led Rehabilitation after Stroke in India (ATTEND) trial was a prospectively randomised open trial with blinded endpoint done across 14 hospitals in India. Patients aged 18 years or older who had had a stroke within the past month, had residual disability and reasonable expectation of survival, and who had an informal family-nominated caregiver were randomly assigned to intervention or usual care by site coordinators using a secure web-based system with minimisation by site and stroke severity. The family members of participants in the intervention group received additional structured rehabilitation training-including information provision, joint goal setting, carer training, and task-specific training-that was started in hospital and continued at home for up to 2 months. The primary outcome was death or dependency at 6 months, defined by scores 3-6 on the modified Rankin scale (range, 0 [no symptoms] to 6 [death]) as assessed by masked observers. Analyses were by intention to treat. This trial is registered with Clinical Trials Registry-India (CTRI/2013/04/003557), Australian New Zealand Clinical Trials Registry (ACTRN12613000078752), and Universal Trial Number (U1111-1138-6707). Between Jan 13, 2014, and Feb 12, 2016, 1250 patients were randomly assigned to intervention (n=623) or control (n=627) groups. 33 patients were lost to follow-up (14 intervention, 19 control) and five patients withdrew (two intervention, three control). At 6 months, 285 (47%) of 607 patients in the intervention group and 287 (47%) of 605 controls were dead or dependent (odds ratio 0·98, 95% CI 0·78-1·23, p=0·87). 72 (12%) patients in the intervention group and 86 (14%) in the control group died (p=0·27), and we observed no difference in rehospitalisation (89 [14%]patients in the intervention group vs 82 [13%] in the control group; p=0·56). We also found no difference in total non-fatal events (112 events in 82 [13%] intervention patients vs 110 events in 79 [13%] control patients; p=0·80). Although task shifting is an attractive solution for health-care sustainability, our results do not support investment in new stroke rehabilitation services that shift tasks to family caregivers, unless new evidence emerges. A future avenue of research should be to investigate the effects of task shifting to health-care assistants or team-based community care.

In 2015, the U.S. Geological Survey’s (USGS) Lake Erie Biological Station (LEBS) successfully completed large vessel surveys in all three of Lake Erie’s basins. Lake Erie Biological Station’s primary vessel surveys included the Western Basin Forage Fish Assessment and East Harbor Fish Community Assessment as well as contributing to the cooperative multi-agency Central Basin Hydroacoustics Assessment, the Eastern Basin Coldwater Community Assessment, and Lower Trophic Level Assessment (see Forage and Coldwater Task Group reports). In 2015, LEBS also initiated a Lake Erie Central Basin Trawling survey in response to the need for forage fish data from Management Unit 3 (as defined by the Yellow Perch Task Group). Results from these surveys contribute to Lake Erie Committee Fish Community Goals and Objectives. Our 2015 vessel operations were initiated in early April and continued into late November. During this time, crews of the R/V Muskie and R/V Bowfin deployed 121 bottom trawls covering 83.2 ha of lake-bottom and catching 105,600 fish totaling 4,065 kg during four separate trawl surveys in the western and central basins of Lake Erie. We deployed and lifted 9.5 km of gillnet, which caught an additional 805 fish, 100 (337 kg) of which were the native coldwater predators Lake Trout, Burbot, and Lake Whitefish (these data are reported in the 2016 Coldwater Task Group report). We also conducted 317 km of hydroacoustic survey transects (reported in the 2016 Forage Task Group report), collected 114 lower trophic (i.e. zooplankton and benthos) samples, and obtained 216 water quality observations (e.g., temperature profiles, and water samples). The LEBS also assisted CLC member agencies with the maintenance and expansion of GLATOS throughout all three Lake Erie sub-basins. Within the following report sections, we describe results from three trawl surveys – the spring and autumn Western Basin Forage Fish Assessment and the East Harbor Forage Fish Assessment – and the Lower Trophic Level Assessment conducted in 2015, and examine trends in the fish community structure and trophic status of Lake Erie. Results of our central basin trawl survey are reported in the 2016 Yellow Perch Task Group report.

The wisdom of crowds for visual search

Decision-making accuracy typically increases through collective integration of people’s judgments into group decisions, a phenomenon known as the wisdom of crowds. For simple perceptual laboratory tasks, classic signal detection theory specifies the upper limit for collective integration benefits obtained by weighted averaging of people’s confidences, and simple majority voting can often approximate that limit. Life-critical perceptual decisions often involve searching large image data (e.g., medical, security, and aerial imagery), but the expected benefits and merits of using different pooling algorithms are unknown for such tasks. Here, we show that expected pooling benefits are significantly greater for visual search than for single-location perceptual tasks and the prediction given by classic signal detection theory. In addition, we show that simple majority voting obtains inferior accuracy benefits for visual search relative to averaging and weighted averaging of observers’ confidences. Analysis of gaze behavior across observers suggests that the greater collective integration benefits for visual search arise from an interaction between the foveated properties of the human visual system (high foveal acuity and low peripheral acuity) and observers’ nonexhaustive search patterns, and can be predicted by an extended signal detection theory framework with trial to trial sampling from a varying mixture of high and low target detectabilities across observers (SDT-MIX). These findings advance our theoretical understanding of how to predict and enhance the wisdom of crowds for real world search tasks and could apply more generally to any decision-making task for which the minority of group members with high expertise varies from decision to decision.

The dorsomedial prefrontal cortex plays a causal role in mediating in-group advantage in emotion recognition: A TMS study.

Consistent evidence suggests that emotional facial expressions are better recognized when the expresser and the perceiver belong to the same social group (in-group advantage). In this study, we used transcranial magnetic stimulation (TMS) to investigate the possible causal involvement of the dorsomedial prefrontal cortex (dmPFC) and of the right temporo-parietal junction (TPJ), two main nodes of the mentalizing neural network, in mediating the in-group advantage in emotion recognition. Participants performed an emotion discrimination task in a minimal (blue/green) group paradigm. We found that interfering with activity in the dmPFC significantly interfered with the effect of minimal group-membership on emotion recognition, reducing participants' ability to discriminate emotions expressed by in-group members. In turn, rTPJ mainly affected emotion discrimination per se, irrespective of group membership. Overall, our results point to a causal role of the dmPFC in mediating the in-group advantage in emotion recognition, favoring intragroup communication. Copyright © 2016 Elsevier Ltd.

Conserved herpesvirus protein kinases

PubMed Central

Gershburg, Edward; Pagano, Joseph S.

2008-01-01

Conserved herpesviral protein kinases (CHPKs) are a group of enzymes conserved throughout all subfamilies of Herpesviridae. Members of this group are serine/threonine protein kinases that are likely to play a conserved role in viral infection by interacting with common host cellular and viral factors; however along with a conserved role, individual kinases may have unique functions in the context of viral infection in such a way that they are only partially replaceable even by close homologues. Recent studies demonstrated that CHPKs are crucial for viral infection and suggested their involvement in regulation of numerous processes at various infection steps (primary infection, nuclear egress, tegumentation), although the mechanisms of this regulation remain unknown. Notwithstanding, recent advances in discovery of new CHPK targets, and studies of CHPK knockout phenotypes have raised their attractiveness as targets for antiviral therapy. A number of compounds have been shown to inhibit the activity of human cytomegalovirus (HCMV)-encoded UL97 protein kinase and exhibit a pronounced antiviral effect, although the same compounds are inactive against Epstein-Barr Virus (EBV)-encoded protein kinase BGLF4, illustrating the fact that low homology between the members of this group complicates development of compounds targeting the whole group, and suggesting that individualized, structure-based inhibitor design will be more effective. Determination of CHPK structures will greatly facilitate this task. PMID:17881303

This study examined the effectiveness of a planned cockpit rest period to improve alertness and performance in long-haul flight operations. The Rest Group (12 crew members) was allowed a planned 40 minute rest period during the low workload, cruise portion of the flight, while the No-Rest Group (9 crew members) had a 40 minute planned control period when they maintained usual flight activities. Measures used in the study included continuous ambulatory recordings of brain wave and eye movement activity, a reaction time/vigilance task, a wrist activity monitor, in-flight fatigue and alertness ratings, a daily log for noting sleep periods, meals, exercise, flight and duty periods, and the NASA Background Questionnaire. The Rest Group pilots slept on 93 percent of the opportunities, falling asleep in 5.6 minutes and sleeping for 25.8 minutes. This nap was associated with improved physiological alertness and performance compared to the No-Rest Group. The benefits of the nap were observed through the critical descent and landing phases of flight. The nap did not affect layover sleep or the cumulative sleep debt. The nap procedures were implemented with minimal disruption to usual flight operations and there were no reported or identified concerns regarding safety.

A Randomized Control Trial of Working Memory Training With and Without Strategy Instruction: Effects on Young Children’s Working Memory and Comprehension

2015-01-01

Researchers are increasingly interested in working memory (WM) training. However, it is unclear whether it strengthens comprehension in young children who are at risk for learning difficulties. We conducted a modest study of whether the training of verbal WM would improve verbal WM and passage listening comprehension, and whether training effects differed between two approaches: training with and without strategy instruction. A total of 58 first-grade children were randomly assigned to 3 groups: WM training with a rehearsal strategy, WM training without strategy instruction, and controls. Every member of the 2 training groups received a one-to-one, 35-minute session of verbal WM training on each of 10 consecutive school days, totaling 5.8 hours. Both training groups improved on trained verbal WM tasks, with the rehearsal group making greater gains. Without correction for multiple group comparisons, the rehearsal group made reliable improvements over controls on an untrained verbal WM task and on passage listening comprehension and listening retell measures. The no-strategy- instruction group outperformed controls on passage listening comprehension. When corrected for multiple contrasts, these group differences disappeared, but were associated with moderate-to-large effect sizes. Findings suggest—however tentatively—that brief but intensive verbal WM training may strengthen the verbal WM and comprehension performance of young children at risk. Necessary caveats and possible implications for theory and future research are discussed. PMID:26156961

Closing the Generational Gap in Surgery: Why So Angry?

PubMed Central

2016-01-01

Summary: Significant and rapid changes in healthcare delivery are forcing surgeons into collaborative teams. Additionally, surgeons are faced with new bureaucratic requirements that do not directly impact patient care, but nevertheless require allocation of time and attention. Surgeons are required to communicate with an expanding group of individuals at various professional levels, adding further stress to daily tasks. Even the method of communication is undergoing rapid transformation. Some surgeons, especially those who are members of the Boomer or X Generation, find this revolution difficult to manage; whereas those who are members of the Y Generation may in fact be better equipped. Surgeons who either refuse to acknowledge these changes or simply lack emotional self-awareness run the risk of being labeled as disruptive. Behavioral techniques are explored which may help those surgeons who are having difficulty. PMID:27826481

BioCreative III interactive task: an overview

PubMed Central

2011-01-01

Background The BioCreative challenge evaluation is a community-wide effort for evaluating text mining and information extraction systems applied to the biological domain. The biocurator community, as an active user of biomedical literature, provides a diverse and engaged end user group for text mining tools. Earlier BioCreative challenges involved many text mining teams in developing basic capabilities relevant to biological curation, but they did not address the issues of system usage, insertion into the workflow and adoption by curators. Thus in BioCreative III (BC-III), the InterActive Task (IAT) was introduced to address the utility and usability of text mining tools for real-life biocuration tasks. To support the aims of the IAT in BC-III, involvement of both developers and end users was solicited, and the development of a user interface to address the tasks interactively was requested. Results A User Advisory Group (UAG) actively participated in the IAT design and assessment. The task focused on gene normalization (identifying gene mentions in the article and linking these genes to standard database identifiers), gene ranking based on the overall importance of each gene mentioned in the article, and gene-oriented document retrieval (identifying full text papers relevant to a selected gene). Six systems participated and all processed and displayed the same set of articles. The articles were selected based on content known to be problematic for curation, such as ambiguity of gene names, coverage of multiple genes and species, or introduction of a new gene name. Members of the UAG curated three articles for training and assessment purposes, and each member was assigned a system to review. A questionnaire related to the interface usability and task performance (as measured by precision and recall) was answered after systems were used to curate articles. Although the limited number of articles analyzed and users involved in the IAT experiment precluded rigorous quantitative analysis of the results, a qualitative analysis provided valuable insight into some of the problems encountered by users when using the systems. The overall assessment indicates that the system usability features appealed to most users, but the system performance was suboptimal (mainly due to low accuracy in gene normalization). Some of the issues included failure of species identification and gene name ambiguity in the gene normalization task leading to an extensive list of gene identifiers to review, which, in some cases, did not contain the relevant genes. The document retrieval suffered from the same shortfalls. The UAG favored achieving high performance (measured by precision and recall), but strongly recommended the addition of features that facilitate the identification of correct gene and its identifier, such as contextual information to assist in disambiguation. Discussion The IAT was an informative exercise that advanced the dialog between curators and developers and increased the appreciation of challenges faced by each group. A major conclusion was that the intended users should be actively involved in every phase of software development, and this will be strongly encouraged in future tasks. The IAT Task provides the first steps toward the definition of metrics and functional requirements that are necessary for designing a formal evaluation of interactive curation systems in the BioCreative IV challenge.

An anesthesia preinduction checklist (APIC) to be performed before anesthesia induction was introduced and evaluated with respect to 5 team-level outcomes, each being a surrogate end point for patient safety: information exchange (the percentage of checklist items exchanged by a team, out of 12 total items); knowledge of critical information (the percentage of critical information items out of 5 total items such as allergies, reported as known by the members of a team); team members' perceptions of safety (the median scores given by the members of a team on a continuous rating scale); their perception of teamwork (the median scores given by the members of a team on a continuous rating scale); and clinical performance (the percentage of completed items out of 14 required tasks, e.g., suction device checked). A prospective interventional study comparing anesthesia teams using the APIC with a control group not using the APIC was performed using a multimethod design. Trained observers rated information exchange and clinical performance during on-site observations of anesthesia inductions. After the observations, each team member indicated the critical information items they knew and their perceptions of safety and teamwork. One hundred five teams using the APIC were compared with 100 teams not doing so. The medians of the team-level outcome scores in the APIC group versus the control group were as follows: information exchange: 100% vs 33% (P < 0.001), knowledge of critical information: 100% vs 90% (P < 0.001), perception of safety: 91% vs 84% (P < 0.001), perception of teamwork: 90% vs 86% (P = 0.028), and clinical performance: 93% vs 93% (P = 0.60). This study provides empirical evidence that the use of a preinduction checklist significantly improves information exchange, knowledge of critical information, and perception of safety in anesthesia teams-all parameters contributing to patient safety. There was a trend indicating improved perception of teamwork.

A Metric to Quantify Shared Visual Attention in Two-Person Teams

NASA Technical Reports Server (NTRS)

Gontar, Patrick; Mulligan, Jeffrey B.

Critical tasks in high-risk environments are often performed by teams, the members of which must work together efficiently. In some situations, the team members may have to work together to solve a particular problem, while in others it may be better for them to divide the work into separate tasks that can be completed in parallel. We hypothesize that these two team strategies can be differentiated on the basis of shared visual attention, measured by gaze tracking.

Dual n-back training increases the capacity of the focus of attention.

2013-02-01

Working memory (WM) training has been reported to benefit abilities as diverse as fluid intelligence (Jaeggi et al., Proceedings of the National Academy of Sciences of the United States of America, 105:6829-6833, 2008) and reading comprehension (Chein & Morrison, Psychonomic Bulletin & Review, 17:193-199, 2010), but transfer is not always observed (for reviews, see Morrison & Chein, Psychonomics Bulletin & Review, 18:46-60, 2011; Shipstead et al., Psychological Bulletin, 138:628-654, 2012). In contrast, recent WM training studies have consistently reported improvement on the trained tasks. The basis for these training benefits has received little attention, however, and it is not known which WM components and/or processes are being improved. Therefore, the goal of the present study was to investigate five possible mechanisms underlying the effects of adaptive dual n-back training on working memory (i.e., improvements in executive attention, updating, and focus switching, as well as increases in the capacity of the focus of attention and short-term memory). In addition to a no-contact control group, the present study also included an active control group whose members received nonadaptive training on the same task. All three groups showed significant improvements on the n-back task from pretest to posttest, but adaptive training produced larger improvements than did nonadaptive training, which in turn produced larger improvements than simply retesting. Adaptive, but not nonadaptive, training also resulted in improvements on an untrained running span task that measured the capacity of the focus of attention. No other differential improvements were observed, suggesting that increases in the capacity of the focus of attention underlie the benefits of adaptive dual n-back training.

Effect of CRM team leader training on team performance and leadership behavior in simulated cardiac arrest scenarios: a prospective, randomized, controlled study.

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 particular guideline adherence and team leader behavior. Emphasis on training of team leader behavior appears to be beneficial in resuscitation and emergency medical course performance.

2010-03-01

In two experiments, we investigated individual differences in the ability to resolve interference in participants diagnosed with major depressive disorder (MDD). Participants were administered the "Ignore/Suppress" task, a short-term memory task composed of two steps. In Step 1 ("ignore"), participants were instructed to memorize a set of stimuli while ignoring simultaneously presented irrelevant material. In Step 2 ("suppress"), participants were instructed to forget a subset of the previously memorized material. The ability to resolve interference was indexed by response latencies on two recognition tasks in which participants decided whether a probe was a member of the target set. In Step 1, we compared response latencies to probes from the to-be-ignored list with response latencies to nonrecently presented items. In Step 2, we compared response latencies to probes from the to-be-suppressed list with response latencies to nonrecently presented items. The results indicate that, compared with control participants, depressed participants exhibited increased interference in the "suppress" but not in the "ignore" step of the task, when the stimuli were negative words. No group differences were obtained when we presented letters instead of emotional words. These findings indicate that depression is associated with difficulty in removing irrelevant negative material from short-term memory.

Leaders in space: Mission commanders and crew on the International Space Station

NASA Astrophysics Data System (ADS)

Brcic, Jelena

Understanding the relationship between leaders and their subordinates is important for building better interpersonal connections, improving group cohesion and cooperation, and increasing task success. This relationship has been examined in many types of groups but not a great amount of analysis has been applied to spaceflight crews. We specifically investigated differences between mission commanders and flight commanders during missions to the International Space Station (ISS). Astronauts and cosmonauts on the ISS participate in long-duration missions (2 to 6 months in length) in which they live and work in close proximity with their 2 or 3 member crews. The leaders are physically distant from their command centres which may result in delay of instructions or important advice. Therefore, the leaders must be able to make quick, sound decisions with unwavering certainty. Potential complications include that the leaders may not be able to exercise their power fully, since material reward or punishment of any one member affects the whole group, and that the leader's actions (or lack thereof) in this isolated, confined environment could create stress in members. To be effective, the mission commander must be able to prevent or alleviate any group conflict and be able to relate to members on an emotional level. Mission commanders and crew are equal in the competencies of spaceflight; therefore, what are the unique characteristics that enable the commanders to fulfill their role? To highlight the differences between commander and crew, astronaut journals, diaries, pre- flight interviews, NASA oral histories, and letters written to family from space were scored and analyzed for values and coping styles. During pre-flight, mission commanders scored higher than other crew members on the values of Stimulation, Security, Universalism, Conformity, Spirituality, and Benevolence, and more often used Self-Control as a coping style. During the long-duration mission on ISS, mission commanders scored higher than crew on the coping style of Accepting Responsibility. These results improve our understanding of the similarities and differences between mission commanders and crew, and suggest areas of importance for the selection and training of future commanders.

Beagle dogs have been utilized extensively in biomedical research. The US Department of Energy`s (DOE) Office of Health and Environmental Research (OHER) has sponsored life-span dose-effect radiation studies in beagles at various laboratories. Because results from studies in the various laboratories were to be compared, all the investigators strove to use similar nomenclature and criteria to describe biological effects. For this reason, pathologists from these laboratories met on five occasions between 1976 and 1977 to discuss nomenclature and histologic criteria for diagnoses. At these meeting, criteria were discussed for histopathologic description of lesions in bone, liver, lung, hematopoietic and lymphoidmore » tissues, mammary gland, pituitary, testis, and thyroid. To provide further assurance of cooperation among the DOE laboratories involved, DOE organized several Task Groups in 1985, composed of staff members from the laboratories. The Task Group on Biological Effects was asked to standardize nomenclature and diagnostic criteria for pathology; this beagle pathology atlas is the result of that request. The atlas describes target organs of particular interest: lungs for radionuclides delivered by inhalation; bones for bone-seeking radionuclides; and hematopoietic and other soft tissues for external irradiation.« less

Deviance as adherence to injunctive group norms: the overlooked role of social identification in deviance.

PubMed

Crane, Monique F; Platow, Michael J

2010-12-01

We currently report three studies investigating group members' expressions of dissatisfaction and discontent with the behaviour and attitudes of their in-group members. Our analysis examines the context in which group members will deviate from actual group member behaviour. We argue that highly identifying group members will challenge fellow group member behaviour when that group member behaviour is perceived to violate injunctive group norms. Further, we predicted that high identifiers would still challenge such group member behaviour even if that behaviour were conducted by a majority of group members. Thus, high identifiers were predicted to express descriptively deviant opinions when the behaviour of other members contravenes injunctive group norms. In Studies 1 and 2, group-level self-definition served as a moderator in the relationship between the expression of discontent and perceived injunctive norm violation; in Study 3, group-level self-investment served as this moderator. The findings supported our predictions. This support was particularly strong when a majority of group members violated group norms. Implications for the analysis of the relationship between social identification and deviance are discussed.

Isolation, confinement, and the characteristics of microgravity will accentuate the need for privacy in the proposed NASA space station, yet limit the mechanism available for achieving it. This study proposes a quantitative model for understanding privacy, interpersonal distancing, and performance, and discusses the practical implications for Space Station design. A review of the relevant literature provided the basis for a database, definitions of physical and psychological distancing, loneliness, and crowding, and a quantitative model of situational privacy. The model defines situational privacy (the match between environment and task), and focuses on interpersonal contact along visual, auditory, olfactory, and tactile dimensions. It involves summing across pairs of crew members, contact dimensions, and time, yet also permits separate analyses of subsets of crew members and contact dimensions. The study concludes that performance will benefit when the type and level of contact afforded by the environment align with that required by the task. The key to achieving this is to design a flexible, definable, and redefinable interior environment that provides occupants with a wide array of options to meet their needs for solitude, limited social interaction, and open group activity. The report presents 49 recommendations in five categories to promote a wide range of privacy options despite the space station's volumetric limitations.

Rationale Impaired emotion processing in schizophrenia predicts broader social dysfunction and has been related to negative symptom severity and amygdala dysfunction. Pharmacological modulation of emotion-processing deficits and related neural abnormalities may provide useful phenotypes for pathophysiological investigation. Objectives We used an acute benzodiazepine challenge to identify and modulate potential emotion-processing abnormalities in 20 unaffected first-degree relatives of individuals with schizophrenia, compared to 25 control subjects without a family history of psychosis. Methods An oral 1mg dose of the short-acting anxiolytic benzodiazepine alprazolam was administered in a balanced crossover placebo-controlled double-blind design, preceding identical 3T fMRI sessions approximately 1 week apart. Primary outcomes included fMRI activity in amygdala and related regions during two facial emotion-processing tasks: emotion identification and emotion memory. Results Family members exhibited abnormally strong alprazolam-induced reduction in amygdala and hippocampus activation during emotion identification, compared to equal reduction in both groups for the emotion memory task. Conclusions GABAergic modulation with alprazolam produced differential responses in family members vs. controls, perhaps by unmasking underlying amygdalar and/or GABAergic abnormalities. Such pharmacological fMRI paradigms could prove useful for developing drugs targeting specific neural circuits to treat or prevent schizophrenia. PMID:21603892

Does the mask govern the mind?: effects of arbitrary gender representation on quantitative task performance in avatar-represented virtual groups.

PubMed

Lee, Jong-Eun Roselyn; Nass, Clifford I; Bailenson, Jeremy N

2014-04-01

Virtual environments employing avatars for self-representation-including the opportunity to represent or misrepresent social categories-raise interesting and intriguing questions as to how one's avatar-based social category shapes social identity dynamics, particularly when stereotypes prevalent in the offline world apply to the social categories visually represented by avatars. The present experiment investigated how social category representation via avatars (i.e., graphical representations of people in computer-mediated environments) affects stereotype-relevant task performance. In particular, building on and extending the Proteus effect model, we explored whether and how stereotype lift (i.e., a performance boost caused by the awareness of a domain-specific negative stereotype associated with outgroup members) occurred in virtual group settings in which avatar-based gender representation was arbitrary. Female and male participants (N=120) were randomly assigned either a female avatar or a male avatar through a process masked as a random drawing. They were then placed in a numerical minority status with respect to virtual gender-as the only virtual female (male) in a computer-mediated triad with two opposite-gendered avatars-and performed a mental arithmetic task either competitively or cooperatively. The data revealed that participants who were arbitrarily represented by a male avatar and competed against two ostensible female avatars showed strongest performance compared to others on the arithmetic task. This pattern occurred regardless of participants' actual gender, pointing to a virtual stereotype lift effect. Additional mediation tests showed that task motivation partially mediated the effect. Theoretical and practical implications for social identity dynamics in avatar-based virtual environments are discussed.

Group Dynamics as a Critical Component of Successful Space Exploration: Conceptual Theory and Insights from the Biosphere 2 Closure Experiment

NASA Astrophysics Data System (ADS)

Nelson, Mark; Allen, John P.

As space exploration and eventually habitation achieves longer durations, successfully managing group dynamics of small, physically isolated groups will become vital. The paper summarizes important underlying research and conceptual theory and how these manifested in a well-documented example: the closure experiments of Biosphere 2. Key research breakthroughs in discerning the operation of small human groups comes from the pioneering work of W.R. Bion. He discovered two competing modalities of behavior. The first is the “task-oriented” or work group governed by shared acceptance of goals, reality-thinking in relation to time, resources and rational, and intelligent management of challenges presented. The opposing, usually unconscious, modality is what Bion called the “basic-assumption” group and alternates between three “group animal” groups: dependency/kill the leader; fight/flight and pairing. If not dealt with, these dynamics work to undermine and defeat the conscious task group’s goal achievement. The paper discusses crew training and selection, various approaches to structuring the work and hierarchy of the group, the importance of contact with a larger population through electronic communication and dealing with the “us-them” syndrome frequently observed between crew and Mission Control. The experience of the first two year closure of Biosphere 2 is drawn on in new ways to illustrate vicissitudes and management of group dynamics especially as both the inside team of biospherians and key members of Mission Control had training in working with group dynamics. Insights from that experience may help mission planning so that future groups in space cope successfully with inherent group dynamics challenges that arise.

The ties that bind: Group membership shapes the neural correlates of in-group favoritism.

Across species, including non-human primates, rodents, and humans, prosocial behavior, the act of helping others, is preferentially provided to members of one's own group. Whereas a particularly ubiquitous example of this is kinship, whereby humans and animals expend greater resources and take more risks for their own kin, in-group prosocial behavior has been demonstrated among diverse shared social groups, including race and culture. In the current study, we made group membership salient by recruiting Chinese and American participants to engage in a prosocial decision-making task during fMRI with an American and Chinese confederate. We found across all participants that donations to the in-group relative to out-group was associated with increased activation in the ventral striatum. Moreover, participants with a greater sense of group identity and Chinese participants relative to American participants, showed heightened activation in self-control (VLPFC, ACC) and mentalizing (TPJ, DMPFC) regions when contributing to the out-group relative to in-group. Our findings provide novel evidence about the neural mechanisms involved in intergroup prosocial behavior. Copyright © 2015 Elsevier Inc. All rights reserved.

On the road to DSM-V and ICD-11.

2008-11-01

Development of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) has been ongoing since 1994, though official release will not occur for another 4 years. Potential revisions are being derived from multiple sources, including building on perceived limitations of DSM-IV; broad-based literature reviews; secondary and primary data analyses; and discussions between global members of the mental health community. The current focus on aligning DSM with the International Classification of Diseases-11 (ICD-11) speaks to the importance of creating a unified text that embraces cross-cutting issues of diagnostics, such as developmental, age-related, and cultural phenomena. International discourse is vital to this process and has been fostered by a National Institutes of Health-sponsored conference series on diagnosis-specific topics. From this series, the DSM-V Task Force developed the following set of revision principals to guide the efforts of the DSM-V Work Groups: grounding recommendations in empirical evidence; maintaining continuity with previous editions of DSM; removing a priori limitations on the amount of changes DSM-V may incur; and maintaining DSM's status as a living document. With work group formation complete, members are currently carrying out the research and revision recommendations proposed during the conference series. Ongoing activities include adding specialized advisors to each work group; completing literature reviews and planning data analyses; and forming study groups to discuss integration of cross-cutting issues (e.g., developmental lifespan factors; formation of diagnostic spectra). The road to DSM-V and ICD-11 has been challenging, but members continue to work diligently in their goal of constructing the most harmonious, scientifically sound, and clinically relevant DSM to date.

Recent research addressed the relationship between staff behaviour and challenging behaviour of individuals with an intellectual disability (ID). Consequently, research on interventions aimed at staff is warranted. The present study focused on the effectiveness of a staff training aimed at emotional intelligence and interactions between staff and clients. The effects of the training on emotional intelligence, coping style and emotions of support staff were investigated. Participants were 214 support staff working within residential settings for individuals with ID and challenging behaviour. The experimental group consisted of 76 staff members, 138 staff members participated in two different control groups. A pre-test, post-test, follow-up control group design was used. Effectiveness was assessed using questionnaires addressing emotional intelligence, coping and emotions. Emotional intelligence of the experimental group changed significantly more than that of the two control groups. The experimental group showed an increase in task-oriented coping, whereas one control group did not. The results with regard to emotions were mixed. Follow-up data revealed that effects within the experimental group were still present four months after the training ended. A staff training aimed at emotional intelligence and staff-client interactions is effective in improving emotional intelligence and coping styles of support staff. However, the need for more research aiming at the relationship between staff characteristics, organisational factors and their mediating role in the effectiveness of staff training is emphasised. © 2014 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Preference for High Status Predicts Implicit Outgroup Bias among Children from Low-Status Groups

2014-01-01

Whereas members of high-status racial groups show ingroup preference when attitudes are measured implicitly, members of low-status racial groups – both adults and children – typically show no bias, potentially reflecting awareness of the ingroup’s low status. We hypothesized that when status differences are especially pronounced, children from low-status groups would show an implicit outgroup bias, the strength of which might relate to attitudes toward status. We tested these predictions among 6–11-year-old Black and Coloured (i.e., multiracial) children from South Africa, a country marked by extreme status differentials among racial groups. As a measure of implicit intergroup bias, children (N=78) completed an Implicit Association Test, a speeded categorization task that assesses the relative strength of association between two target groups (in the present study, either Whites vs. Blacks or Whites vs. Coloureds) and positive versus negative evaluation. Children also completed explicit (i.e., self-report) measures of attitudes toward racial groups, as well as rich and poor people (a measure of attitudes toward status). Both groups of children showed an implicit outgroup-favoring (i.e., pro-White) bias, suggesting that children were sensitive to the extent of status differences. The only instance in which implicit pro-White bias did not emerge involved Black children’s evaluations of Whites versus Coloureds, both higher-status outgroups. Explicit preference for high status predicted implicit pro-White bias, particularly when the IAT contrasted two outgroups. The impact of status on the development of implicit and explicit intergroup bias is discussed. PMID:24219317

Perceptual advantages for own-race compared to other-race faces have been demonstrated for the recognition of facial identity and expression. However, these effects have not been investigated in the same study with measures that can determine the extent of cross-cultural agreement as well as differences. To address this issue, we used a photo sorting task in which Chinese and Caucasian participants were asked to sort photographs of Chinese or Caucasian faces by identity or by expression. This paradigm matched the task demands of identity and expression recognition and avoided constrained forced-choice or verbal labelling requirements. Other-race effects of comparable magnitude were found across the identity and expression tasks. Caucasian participants made more confusion errors for the identities and expressions of Chinese than Caucasian faces, while Chinese participants made more confusion errors for the identities and expressions of Caucasian than Chinese faces. However, analyses of the patterns of responses across groups of participants revealed a considerable amount of underlying cross-cultural agreement. These findings suggest that widely repeated claims that members of other cultures "all look the same" overstate the cultural differences.

Mental and Physical Workload, Salivary Stress Biomarkers and Taste Perception: Mars Desert Research Station Expedition

2012-01-01

Background: Very few studies have been conducted on the effects of simulation of Mars conditions on taste. Aims: This study was planned to find the effects of physical and mental workload on taste sensitivity and salivary stress biomarkers. Materials and Methods: Twelve crew members were selected. Taste reactions and intensity of the taste sensations to quinine sulfate, citric acid, and sucrose were tested before and after mental and physical tasks for one hour. Also, psychological mood states by profile of mood state, salivary, salivary alpha amylase and cortisol, and current stress test scores were measured before and after mental and physical tasks. Results: Average time intensity evaluation showed that after the mental and physical tasks, the perceived duration of bitter, sour, and sweet taste sensations was significantly shortened relative to control group. There were good correlations between average time intensity of sweetness, bitterness, sourness and cortisol levels. Conclusions: Taste alterations due to stress can have an effect on the health and confidence of astronauts in long- term space missions. Thus, this issue remains one of the important issues for future human explorations. PMID:23181230

The Changing Landscape of Undergraduate Physics

2006-11-01

The National Task Force on Undergraduate Physics was convened by APS, AAPT and AIP to study the steep decline in the number of physics majors that occurred during the 1990s. The Task Force conducted project SPIN-UP (Strategic Programs for Innovations in Undergraduate Physics) to investigate why some departments were thriving while others are losing majors. With support from the ExxonMobil Foundation, we conducted site visits to 21 ``thriving'' departments and have worked with the AIP statistics program to survey the 562 departments that grant undergraduate degrees in physics. The results of the study identified key ingredients in thriving departments and essential elements needed to make changes that respond to the changing environments in which physics departments find themselves. Today, enrollments in undergraduate physics are climbing again. We need to ensure that this positive trend continues and ensure that we attract women and members of underrepresented groups to the study of physics.

Pyrrhic victories: the need for social status drives costly competitive behavior.

2013-01-01

Competitive behavior is commonly defined as the decision to maximize one's payoffs relative to others. We argue instead that competitive drive derives from a desire for social status. We make use of a multi-player auction task in which subjects knowingly incur financial losses for the sake of winning auctions. First, we show that overbidding is increased when the task includes members of a rival out-group, suggesting that social identity is an important mediator of competitiveness. In addition, we show that the extent that individuals are willing to incur losses is related to affective responses to social comparisons but not to monetary outcomes. Second, we show that basal levels of testosterone predict overbidding, and that this effect of testosterone is mediated by affective responses to social comparisons. Based on these findings, we argue that competitive behavior should be conceptualized in terms of social motivations as opposed to just relative monetary payoffs.

The Asian/Pacific Islander Youth Violence Prevention Center (APIYVPC) focuses its youth violence prevention efforts on community mobilization by partnering with Kailua High School and other local community groups. This paper describes the development and activities of the Safe School Task Force (SSTF) and the lessons learned. In response to concerns of school, community members, and students, the SSTF was organized to promote student leadership in raising awareness about problems related to violence. Collaboration among the school, community, and the university places students in leadership roles to reduce school violence and enhances their self-efficacy to improve their school environment. To increase SSTF effectiveness, more attention must be paid to student recruitment, consistent community partnerships, and gaining teacher buy-in. This partnership may be useful in multicultural communities to provide students the opportunities to learn about violence prevention strategies, community mobilization, and leadership skills.

Objectives  To revise an existing three-talk model for learning how to achieve shared decision making, and to consult with relevant stakeholders to update and obtain wider engagement. Design  Multistage consultation process. Setting  Key informant group, communities of interest, and survey of clinical specialties. Participants  19 key informants, 153 member responses from multiple communities of interest, and 316 responses to an online survey from medically qualified clinicians from six specialties. Results  After extended consultation over three iterations, we revised the three-talk model by making changes to one talk category, adding the need to elicit patient goals, providing a clear set of tasks for each talk category, and adding suggested scripts to illustrate each step. A new three-talk model of shared decision making is proposed, based on "team talk," "option talk," and "decision talk," to depict a process of collaboration and deliberation. Team talk places emphasis on the need to provide support to patients when they are made aware of choices, and to elicit their goals as a means of guiding decision making processes. Option talk refers to the task of comparing alternatives, using risk communication principles. Decision talk refers to the task of arriving at decisions that reflect the informed preferences of patients, guided by the experience and expertise of health professionals. Conclusions  The revised three-talk model of shared decision making depicts conversational steps, initiated by providing support when introducing options, followed by strategies to compare and discuss trade-offs, before deliberation based on informed preferences.

Okyere, Eunice; Mwanri, Lillian; Ward, Paul

2017-01-01

Objective To explore the experiences and perceptions of health workers and implementers of task-shifting in rural health facilities in Upper East Region, Ghana. Methods Data was collected through field interviews. A total of sixty eight (68) in-depth interviews were conducted with health workers’ in primary health care facilities (health centres); Four in-depth interviews with key persons involved in staff management was conducted to understand how task-shifting is organised including its strengths and challenges. The health workers interview guide was designed with the aim of getting data on official tasks of health workers, additional tasks assigned to them, how they perceive these tasks, and the challenges associated with the practice of task-shifting. Findings Task-shifting is a practice being used across the health facilities in the study area to help reduce the impact of insufficient health workers. Generally, health workers had a comprehensive training that supported the organisation of task-shifting. However, staff members’ are sometimes engaged in tasks above their level of training and beyond their actual job descriptions. Adequate training is usually not provided before additional tasks are assigned to staff members. Whilst some health workers perceived the additional tasks they performed as an opportunity to learn new skills, others described these as stressful and overburdening. Conclusion Task-shifting has the potential to contribute to addressing the insufficient health workforce, and thereby improving health delivery system where the procedures are well defined and staff members work in a coordinated and organised manner. The provision of adequate training and supervision for health workers is important in order to improve their expertise before additional tasks are assigned to them so that the quality of care would not be compromised.

Perceptual Averaging in Individuals with Autism Spectrum Disorder.

PubMed

Corbett, Jennifer E; Venuti, Paola; Melcher, David

2016-01-01

There is mounting evidence that observers rely on statistical summaries of visual information to maintain stable and coherent perception. Sensitivity to the mean (or other prototypical value) of a visual feature (e.g., mean size) appears to be a pervasive process in human visual perception. Previous studies in individuals diagnosed with Autism Spectrum Disorder (ASD) have uncovered characteristic patterns of visual processing that suggest they may rely more on enhanced local representations of individual objects instead of computing such perceptual averages. To further explore the fundamental nature of abstract statistical representation in visual perception, we investigated perceptual averaging of mean size in a group of 12 high-functioning individuals diagnosed with ASD using simplified versions of two identification and adaptation tasks that elicited characteristic perceptual averaging effects in a control group of neurotypical participants. In Experiment 1, participants performed with above chance accuracy in recalling the mean size of a set of circles ( mean task ) despite poor accuracy in recalling individual circle sizes ( member task ). In Experiment 2, their judgments of single circle size were biased by mean size adaptation. Overall, these results suggest that individuals with ASD perceptually average information about sets of objects in the surrounding environment. Our results underscore the fundamental nature of perceptual averaging in vision, and further our understanding of how autistic individuals make sense of the external environment.

The imitation game: Effects of social cues on 'imitation' are domain-general in nature.

PubMed

Marsh, Lauren E; Bird, Geoffrey; Catmur, Caroline

2016-10-01

Imitation has been hailed as 'social glue', facilitating rapport with others. Previous studies suggest that social cues modulate imitation but the mechanism of such modulation remains underspecified. Here we examine the locus, specificity, and neural basis of the social control of imitation. Social cues (group membership and eye gaze) were manipulated during an imitation task in which imitative and spatial compatibility could be measured independently. Participants were faster to perform compatible compared to incompatible movements in both spatial and imitative domains. However, only spatial compatibility was modulated by social cues: an interaction between group membership and eye gaze revealed more spatial compatibility for ingroup members with direct gaze and outgroup members with averted gaze. The fMRI data were consistent with this finding. Regions associated with the control of imitative responding (temporoparietal junction, inferior frontal gyrus) were more active during imitatively incompatible compared to imitatively compatible trials. However, this activity was not modulated by social cues. On the contrary, an interaction between group, gaze and spatial compatibility was found in the dorsolateral prefrontal cortex in a pattern consistent with reaction times. This region may be exerting control over the motor system to modulate response inhibition. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

Compelling Evidence that Exposure Therapy for PTSD Normalizes Brain Function.

PubMed

Roy, Michael J; Costanzo, Michelle E; Blair, James R; Rizzo, Albert A

2014-01-01

Functional magnetic resonance imaging (fMRI) is helping us better understand the neurologic pathways involved in posttraumatic stress disorder (PTSD). We previously reported that military service members with PTSD after deployment to Iraq or Afghanistan demonstrated significant improvement, or normalization, in the fMRI-measured activation of the amygdala, prefrontal cortex and anterior cingulate gyrus following exposure therapy for PTSD. However, our original study design did not include repeat scans of control participants, rendering it difficult to discern how much of the observed normalization in brain activity is attributable to treatment, rather than merely a practice effect. Using the same Affective Stroop task paradigm, we now report on a larger sample of PTSD-positive combat veterans that we treated with exposure therapy, as well as a combat-exposed control group of service members who completed repeat scans at 3-4 month intervals. Findings from the treatment group are similar to our prior report. Combat controls showed no significant change on repeat scanning, indicating that the observed differences in the intervention group were in fact due to treatment. We continue to scan additional study participants, in order to determine whether virtual reality exposure therapy has a different impact on regional brain activation than other therapies for PTSD.

Psychophysical testing of visual prosthetic devices: a call to establish a multi-national joint task force

Recent advances in the field of visual prostheses, as showcased in this special feature of Journal of Neural Engineering , have led to promising results from clinical trials of a number of devices. However, as noted by these groups there are many challenges involved in assessing vision of people with profound vision loss. As such, it is important that there is consistency in the methodology and reporting standards for clinical trials of visual prostheses and, indeed, the broader vision restoration research field. Two visual prosthesis research groups, the Boston Retinal Implant Project (BRIP) and Bionic Vision Australia (BVA), have agreed to work cooperatively to establish a multi-national Joint Task Force. The aim of this Task Force will be to develop a consensus statement to guide the methods used to conduct and report psychophysical and clinical results of humans who receive visual prosthetic devices. The overarching goal is to ensure maximum benefit to the implant recipients, not only in the outcomes of the visual prosthesis itself, but also in enabling them to obtain accurate information about this research with ease. The aspiration to develop a Joint Task Force was first promulgated at the inaugural 'The Eye and the Chip' meeting in September 2000. This meeting was established to promote the development of the visual prosthetic field by applying the principles of inclusiveness, openness, and collegiality among the growing body of researchers in this field. These same principles underlie the intent of this Joint Task Force to enhance the quality of psychophysical research within our community. Despite prior efforts, a critical mass of interested parties could not congeal. Renewed interest for developing joint guidelines has developed recently because of a growing awareness of the challenges of obtaining reliable measurements of visual function in patients who are severely visually impaired (in whom testing is inherently noisy), and of the importance of comparing outcomes amongst the many research teams that have entered this field, all of which are using different devices implanted at various locations within the visual system and different methods of assessing efficacy. Researchers at the BRIP and BVA believe that use of common methods for testing and for reporting results would benefit all scientists and clinicians in the field, the agencies that regulate human testing, corporations that are invested in the success of this field, and, most importantly, potential patients. The Task Force will be formed with the intent of developing substantive recommendations to provide a measure of consistency and quality control within the field. The guidelines will offer recommendations for the assessment of the: (1) baseline (pre-implant) visual status of potential patients (including specification of the disease diagnosis and impact on visual functioning) and (2) post-operative visual function. The guidelines will be available to the public, research groups and companies. Any groups that choose to adopt the recommendations would be encouraged to include a formal statement of compliance in their presentations and publications. The Task Force will develop these guidelines with the understanding that the ability to perform experiments in the suggested manner might be limited by the particular engineering design and functionality of different prosthesis devices. It is not the intent of the Task Force to write strict test protocols for all parties to follow, but instead to work cooperatively as a research field to develop guidelines about the types of tests that should be implemented, and how they could be reported in a similar format between groups. The opportunity to participate on the Task Force is open to all researchers, clinicians and other specialists who work in the fields of sensory prostheses (both visual and cochlear implants), molecular therapy, stem cells, optogenetics or other fields that share a similar goal of restoring vision to the blind. Decisions about the guidelines will be made democratically, with precautions to prevent any one group or company from having a more dominant voice than any other. One or more smaller working groups may be established to delve more deeply into specific issues, like the ethics of testing or governance structure, and to develop specific wording for recommendations that would be voted on by the entire Task Force group. Ultimately, the various recommendations, once approved democratically, will serve as the consensus document for the Multi-National Joint Task Force. The full list of members of the Task Force and the rules of governance will be published to promote transparency. The Joint Task force will post its guidelines with all signatories on a dedicated page within the website of the Henry Ford Department of Ophthalmology (Detroit). This site was chosen in recognition of the consistent support that Phillip Hessburg MD and the Board of Directors of the Detroit Institute of Ophthalmology, which has recently merged with the Henry Ford Department of Ophthalmology, have so generously and selflessly provided to our field over the past 14 years. This website will also contain a list of all human psychophysical testing that has been performed in the visual prosthetic field, with designations for those studies that were performed in accordance with the guidelines of the Multi-National Task Force, which will assume responsibility for the accuracy of the material. For those who wish to join this Task Force or have further questions, Dr Rizzo and Dr Ayton can be contacted at the email addresses listed above. The founding members of the Task Force anticipate that this digital resource will prove valuable to anyone who has interest in learning more about the achievements in our field, especially our prospective patients, to whom we dedicate our work.

We developed a course to introduce incoming third-year medical students to the subject of patient safety, to focus their attention on teamwork and communication, and to create an awareness of patient-safe practices that will positively impact their performance as clinicians. The course, held prior to the start of clinical rotations, consisted of lectures, web-based didactic materials, small group activities and simulation exercises, with an emphasis on experiential learning. First, students inspected a 'room of horrors', which is a simulated clinical environment riddled with errors. Second, we used lenticular puzzles in small groups to elicit teamwork behaviours that parallel real-life interactions in health care. Each team was given 8 minutes to complete a 48-piece puzzle, with five pieces removed at random and given to other teams. The salient teaching point of this exercise is that for a team to complete the task, team members must communicate with members of their own team as well as with other teams. Last, simulation scenarios provided a clinical context to reinforce the skills introduced through the puzzle exercise and lectures. The students were split into groups of six or seven members and challenged with two scenarios. Both scenarios focused on a 56-year-old man in respiratory distress. The teams were debriefed on both clinical management and teamwork. The vast majority of the students (93%) agreed that the course improved their patient safety knowledge and skills. The positive response from students to the introductory course is an important step in fostering a culture of patient safety. © Blackwell Publishing Ltd 2012.

Activities of enzymes involved in muscle damage [creatine kinase (CK) and aspartate aminotransferase (AST)] and levels of malondialdehyde (MDA) as a marker of oxidative stress were monitored in the plasma of 27 members of an America's Cup yachting crew. The preventive benefits of allopurinol on muscle damage were also tested. In racing period A, the crew was divided into two groups according to their tasks on board. Blood samples from all 27 sailors were obtained before the start of a 5-day fleet race, after the last race, and after the ten match races. In period B, crew members were divided at random into two groups. One group (13 participants) received 300 mg/day of allopurinol 3 h before racing. The other ten members received placebo. Blood samples were collected just before and after the second round of the Louis Vuitton Cup. All participants showed increased CK and AST activities after the racing period A. The increase in CK activity was highest in sailors involved in strenuous physical work. At the end of period A, plasma MDA levels were higher in all participants as compared with non-participant athletes. In period B, a significant decrease in CK activity, but not in AST, appeared among participants receiving allopurinol. Plasma MDA decreased in sailors treated with allopurinol, but this reduction did not reach statistical significance. America's Cup is a sailing sport with high physical demands, as shown by the increase in muscle-damage markers. Treatment with allopurinol appeared to decrease the levels of muscle damage markers.

The Union for International Cancer Control (UICC) is a membership-based, non-governmental organization with a mandate to “…to unite the cancer community to reduce the global cancer burden, to promote greater equity, and to integrate cancer control into the world health and development agenda.” COMP is an associate member of the UICC. It is well recognized by the UICC that there are major gaps between high, and low and middle income countries, in terms of access to cancer services including access to radiation therapy. In this context, the UICC has developed a Global Task Force on Radiotherapy for Cancer Control withmore » a charge to answer a single question: “What does it cost to close the gap between what exists today and reasonable access to radiotherapy globally?” The Task Force consists of leaders internationally recognized for their radiation treatment related expertise (radiation oncologists, medical physicists, radiation therapists) as well as those with global health and economics specialization. The Task Force has developed three working groups: (1) to look at the global burden of cancer; (2) to look at the infrastructure requirements (facilities, equipment, personnel); and (3) to consider outcomes in terms of numbers of lives saved and palliated patients. A report is due at the World Cancer Congress in December 2014. This presentation reviews the infrastructure considerations under analysis by the second work group. The infrastructure parameters being addressed include capital costs of buildings and equipment and operating costs, which include human resources, equipment servicing and quality control, and general overhead.« less

Web-based technology is critical to the future of healthcare. As part of the Safe Kidney Care cohort study evaluating patient safety in CKD, this study determined how effectively a representative sample of patients with CKD or family members could interpret and use the Safe Kidney Care website (www.safekidneycare.org), an informational website on safety in CKD. Between November of 2011 and January of 2012, persons with CKD or their family members underwent formal usability testing administered by a single interviewer with a second recording observer. Each participant was independently provided a list of 21 tasks to complete, with each task rated as either easily completed/noncritical error or critical error (user cannot complete the task without significant interviewer intervention). Twelve participants completed formal usability testing. Median completion time for all tasks was 17.5 minutes (range=10-44 minutes). In total, 10 participants had greater than or equal to one critical error. There were 55 critical errors in 252 tasks (22%), with the highest proportion of critical errors occurring when participants were asked to find information on treatments that may damage kidneys, find the website on the internet, increase font size, and scroll to the bottom of the webpage. Participants were generally satisfied with the content and usability of the website. Web-based educational materials for patients with CKD should target a wide range of computer literacy levels and anticipate variability in competency in use of the computer and internet.

Patient-centred care based on needs has been gaining momentum in health policy and the workforce. This creates new demand for interprofessional teams and redefining roles and tasks of professionals, yet little is known on how to implement new health policies more effectively. Our aim was to analyse the role and capacity of health professions in driving organisational change in interprofessional working and patient-centred care. A case study of the introduction of interprofessional, early discharge teams in stroke rehabilitation in Denmark was conducted with focus on day-to-day coordination of care tasks and the professional groups' interests and strategies. The study included 5 stroke teams and 17 interviews with different health professionals conducted in 2015. Professional groups expressed highly positive professional interest in reorganised stroke rehabilitation concerning patients, professional practice and intersectoral relations; individual professional and collective interprofessional interests strongly coincided. The corresponding strategies were driven by a shared goal of providing needs-based care for patients. Individual professionals worked independently and on behalf of the team. There was also a degree of skills transfer as individual team members screened patients on behalf of other professional groups. The study identified supportive factors and contexts of patient-centred care. This highlights capacity to improve health workforce governance through professional participation, which should be explored more systematically in a wider range of healthcare services.

People believe that they can respond effectively to threats, but actually they experience difficulties in disengaging from ongoing tasks and shifting their attention to life-threatening events. We contend that this tendency is especially true for secure people with respect to their worldview and perception of others and not for insecure individuals. In Study 1 (N = 290), we examined individuals' reactions to various threat scenarios. In Study 2 (N = 65), we examined these reactions using a behavioral design high in ecological validity. In Study 3 (N = 78), we examined group-level benefits for the actions of insecure individuals by manipulating asocial behavior in response to an emergency. Study 1 indicated that anxiously attached individuals stayed away from threats and sought help; avoidant people tended to take action by either assessing the risk of the event and/or enacting an asocial action such as fight or flight. Study 2 added ecological validity to these findings, and Study 3 showed that priming asocial behavior responses promoted actions that increased group members' chances of survival. Results validate the central tenets of social defense theory and indicate that actions that are deemed asocial may paradoxically promote the survival of individuals and groups. © 2017 Wiley Periodicals, Inc.

2008-04-01

We placed anaesthesia teams into a stressful environment in order to explore interactions between members of different professional groups and to investigate their perspectives on the impact of these interactions on team performance. Ten anaesthetists, 5 nurses and 5 trained anaesthetic assistants each participated in 2 full-immersion simulations of critical events using a high-fidelity computerised patient simulator. Their perceptions of team interactions were explored through questionnaires and semi-structured interviews. Written questionnaire data and interview transcriptions were entered into N6 qualitative software. Data were analysed by 2 investigators for emerging themes and coded to produce reports on each theme. We found evidence of limited understanding of the roles and capabilities of team members across professional boundaries, different perceptions of appropriate roles and responsibilities for different members of the team, limited sharing of information between team members and limited team input into decision making. There was a perceived impact on task distribution and the optimal utilisation of resources within the team. Effective management of medical emergencies depends on optimal team function. We have identified important factors affecting interactions between different health professionals in the anaesthesia team, and their perceived influences on team function. This provides evidence on which to build appropriate and specific strategies for interdisciplinary team training in operating theatre staff.

The second annual Geosciences Congressional Visits Day (Geo-CVD), on 15-16 September 2009, came at a time when the U.S. Congress is considering a number of issues intimately connected to the geosciences, including energy, the environment, and climate. Nearly 60 geoscientists from across the country, including 22 AGU members from 12 states, participated in this year's event by discussing geoscience issues with members of Congress and their staffs. AGU cosponsored the event along with nine other Earth and space science societies that work together on geoscience policy issues as part of the Geopolicy Working Group in Washington, D. C. Geo-CVD kicked off with the U.S. Geological Survey (USGS) Coalition's annual reception on Capitol Hill on 14 September. AGU is a member of the USGS Coalition, which includes several other science societies, and this year AGU organized the reception together with the Seismological Society of America. At the reception, U.S. senators Dianne Feinstein (D-Calif.) and Lisa Murkowski (R-Alaska) received the coalition's annual Leadership Award in recognition of their continuing commitment to USGS. Sen. Feinstein chairs the Senate Appropriations Subcommittee on Interior, Environment, and Related Issues, which is tasked with allocating funds to USGS; Sen. Murkowski is the ranking member on the Senate Committee on Energy and Natural Resources.

BARTER: Behavior Profile Exchange for Behavior-Based Admission and Access Control in MANETs

NASA Astrophysics Data System (ADS)

Frias-Martinez, Vanessa; Stolfo, Salvatore J.; Keromytis, Angelos D.

Mobile Ad-hoc Networks (MANETs) are very dynamic networks with devices continuously entering and leaving the group. The highly dynamic nature of MANETs renders the manual creation and update of policies associated with the initial incorporation of devices to the MANET (admission control) as well as with anomaly detection during communications among members (access control) a very difficult task. In this paper, we present BARTER, a mechanism that automatically creates and updates admission and access control policies for MANETs based on behavior profiles. BARTER is an adaptation for fully distributed environments of our previously introduced BB-NAC mechanism for NAC technologies. Rather than relying on a centralized NAC enforcer, MANET members initially exchange their behavior profiles and compute individual local definitions of normal network behavior. During admission or access control, each member issues an individual decision based on its definition of normalcy. Individual decisions are then aggregated via a threshold cryptographic infrastructure that requires an agreement among a fixed amount of MANET members to change the status of the network. We present experimental results using content and volumetric behavior profiles computed from the ENRON dataset. In particular, we show that the mechanism achieves true rejection rates of 95% with false rejection rates of 9%.

2012-01-01

PURPOSE Primary care faces the dilemma of excessive patient panel sizes in an environment of a primary care physician shortage. We aimed to estimate primary care panel sizes under different models of task delegation to nonphysician members of the primary care team. METHODS We used published estimates of the time it takes for a primary care physician to provide preventive, chronic, and acute care for a panel of 2,500 patients, and modeled how panel sizes would change if portions of preventive and chronic care services were delegated to nonphysician team members. RESULTS Using 3 assumptions about the degree of task delegation that could be achieved (77%, 60%, and 50% of preventive care, and 47%, 30%, and 25% of chronic care), we estimated that a primary care team could reasonably care for a panel of 1,947, 1,523, or 1,387 patients. CONCLUSIONS If portions of preventive and chronic care services are delegated to nonphysician team members, primary care practices can provide recommended preventive and chronic care with panel sizes that are achievable with the available primary care workforce.

Objective: The objective is to formulate clinical practice guidelines for treating Cushing's syndrome. Participants: Participants include an Endocrine Society-appointed Task Force of experts, a methodologist, and a medical writer. The European Society for Endocrinology co-sponsored the guideline. Evidence: The Task Force used the Grading of Recommendations, Assessment, Development, and Evaluation system to describe the strength of recommendations and the quality of evidence. The Task Force commissioned three systematic reviews and used the best available evidence from other published systematic reviews and individual studies. Consensus Process: The Task Force achieved consensus through one group meeting, several conference calls, and numerous e-mail communications. Committees and members of The Endocrine Society and the European Society of Endocrinology reviewed and commented on preliminary drafts of these guidelines. Conclusions: Treatment of Cushing's syndrome is essential to reduce mortality and associated comorbidities. Effective treatment includes the normalization of cortisol levels or action. It also includes the normalization of comorbidities via directly treating the cause of Cushing's syndrome and by adjunctive treatments (eg, antihypertensives). Surgical resection of the causal lesion(s) is generally the first-line approach. The choice of second-line treatments, including medication, bilateral adrenalectomy, and radiation therapy (for corticotrope tumors), must be individualized to each patient. PMID:26222757

Many researchers have suggested team processes that enhance team performance. However, past team process models were based on crew team, whose all team members perform an indivisible temporary task. These models may be inapplicable business teams, whose individual members perform middle- and long-term tasks assigned to individual members. This study modified the teamwork model of Dickinson and McIntyre (1997) and aimed to demonstrate a whole team process that enhances the performance of business teams. We surveyed five companies (member N = 1,400, team N = 161) and investigated team-level-processes. Results showed that there were two sides of team processes: "communication" and "collaboration to achieve a goal." Team processes in which communication enhanced collaboration improved team performance with regard to all aspects of the quantitative objective index (e.g., current income and number of sales), supervisor rating, and self-rating measurements. On the basis of these results, we discuss the entire process by which teamwork enhances team performance in business organizations.

This field study examines the joint effects of social exchange relationships at work (leader-member exchange and team-member exchange) and employee personality (conscientiousness and agreeableness) in predicting task performance and citizenship performance. Consistent with trait activation theory, matched data on 230 employees, their coworkers, and their supervisors demonstrated interactions in which high quality social exchange relationships weakened the positive relationships between personality and performance. Results demonstrate the benefits of consonant predictions in which predictors and outcomes are matched on the basis of specific targets. We discuss theoretical and practical implications.

This experiment develops an integrative, path-analytic model for the endorsement accorded formal leaders. The model contains four independent variables reflecting aspects of group structure (i.e., group success-failure, the payoff distribution, the degree of support by others members for the leader, and the vulnerability of the leader). Also included are two intervening variables reflecting perceptual processes (attributed competence and attributed fairness), and one dependent variable endorsement). The results indicate that endorsement is greater when the group's success is high, when the payoff distribution is flat rather than hierarchial, and when the leader is not vulnerable to removal from office. Other support had no significant impact on endorsement. Analyses further demonstrate that the effect of success-failure on endorsement is mediated by attributed competence, while the effect of the payoff distributed is mediated by attributed fairness. These results suggest that moral and task evaluations are distinct bases of endorsement.

Effects of speech intelligibility level on concurrent visual task performance.

PubMed

Payne, D G; Peters, L J; Birkmire, D P; Bonto, M A; Anastasi, J S; Wenger, M J

1994-09-01

Four experiments were performed to determine if changes in the level of speech intelligibility in an auditory task have an impact on performance in concurrent visual tasks. The auditory task used in each experiment was a memory search task in which subjects memorized a set of words and then decided whether auditorily presented probe items were members of the memorized set. The visual tasks used were an unstable tracking task, a spatial decision-making task, a mathematical reasoning task, and a probability monitoring task. Results showed that performance on the unstable tracking and probability monitoring tasks was unaffected by the level of speech intelligibility on the auditory task, whereas accuracy in the spatial decision-making and mathematical processing tasks was significantly worse at low speech intelligibility levels. The findings are interpreted within the framework of multiple resource theory.

Fong de los Santos, L; Dong, L; Greener, A

Purpose: AAPM Task Group (TG) 275 is charged with developing riskbased guidelines for plan and chart review clinical processes. As part of this work an AAPM-wide survey was conducted to gauge current practices. Methods: The survey consisted of 103 multiple-choice questions covering the following review processes for external beam including protons: 1) Initial Plan Check, 2) On-Treatment and 3) End-of-Treatment Chart Check. The survey was designed and validated by TG members with the goal of providing an efficient and easy response process. The survey, developed and deployed with the support of AAPM headquarters, was released to all AAPM members whomore » have self-reported as working in the radiation oncology field and it was kept open for 7 weeks. Results: There are an estimated 4700 eligible participants. At the time of writing, 962 completed surveys have been collected with an average completion time of 24 minutes. Participants are mainly from community hospitals (40%), academicaffiliated hospitals (31%) and free-standing clinics (18%). Among many other metrics covered on the survey, results so far indicate that manual review is an important component on the plan and chart review process (>90%) and that written procedures and checklists are widely used (>60%). However, the details of what is reviewed or checked are fairly heterogeneous among the sampled medical physics community. Conclusion: The data gathered from the survey gauging current practices will be used by TG 275 to develop benchmarks and recommendations for the type and extent of checks to perform effective physics plan and chart review processes.« less

If you get better, will I? An actor-partner analysis of the mutual influence of group therapy outcomes.

The effectiveness of group psychotherapy has been empirically studied and supported over several decades; however, there remains much to understand regarding the specific factors contributing to effective group psychotherapy. The current study uses Kashy and Kenny's (2000) actor-partner interdependence model (APIM) to examine the relationship between an individual group member's outcome and the outcomes of the other group members. This is the first study to examine the effects of the outcomes of other therapy group members on those of individual members. Specifically, we examined the relationship between an individual group member's presymptom score, the aggregated presymptom scores of the other group members, and the aggregated pre- to postsymptom change of the other group members on an individual group member's pre- to postsymptom change. We analyzed the change in pre-post posttraumatic stress disorder (PTSD) symptoms of 105 women in 16 trauma-informed groups in a women's correctional facility. As hypothesized, an individual's presymptom measure (actor effect) and the aggregated presymptom measures of the other group members (partner effect) were positively related to the individual's change in PTSD symptoms. Contrary to our hypothesis, the aggregated pre-post change in PTSD symptom measures of the other group members (partner effect) was negatively associated with the pre-post change in PTSD symptom measures of an individual group member. Social comparison theory is discussed as an explanation for why a group member would report lowered amounts of change when in a group with others who are reporting a higher amount of change. Implications for research and practice are discussed.

Leadership skills directly correlate with the quality of technical performance of cardiopulmonary resuscitation (CPR) and clinical outcomes. Despite an improved focus on non-technical skills in CPR training, the leadership of cardiac arrests is often variable. To assess the perceptions of leadership and team working among members of a cardiac arrest team and to evaluate future training needs. Cross-sectional survey of 102 members of a cardiac arrest team at an Acute Hospital Trust in the UK with 892 inpatient beds. Responses sought from doctors, nurses and healthcare assistants to 12 rated statements and 4 dichotomous questions. Of 102 responses, 81 (79%) were from doctors and 21 (21%) from nurses. Among specialist registrars 90% agreed or strongly agreed that there was clear leadership at all arrests compared with between 28% and 49% of nurses and junior doctors respectively. Routine omission of key leadership tasks was reported by as many as 80% of junior doctors and 50% of nurses. Almost half of respondents reported non-adherence with Advanced Life Support (ALS) guidelines. Among junior members of the team, 36% felt confident to lead an arrest and 75% would welcome further dedicated cardiac arrest leadership training. Leadership training is integrated into the ALS (Resus Council, UK) qualification. However, this paper found that in spite of this training; standards of leadership are variable. The findings suggest a pressing need for further dedicated cardiac arrest leadership training with a focus on improving key leadership tasks such as role assignment, team briefing and debriefing.

Yanke, Eric; Moriarty, Helene; Carayon, Pascale; Safdar, Nasia

2018-06-11

Using a novel human factors engineering approach, the Systems Engineering Initiative for Patient Safety model, we evaluated environmental service workers' (ESWs) perceptions of barriers and facilitators influencing adherence to the nationally mandated Department of Veterans Affairs Clostridium difficile infection (CDI) prevention bundle. A focus group of ESWs was conducted. Qualitative analysis was performed employing a visual matrix display to identify barrier/facilitator themes related to Department of Veterans Affairs CDI bundle adherence using the Systems Engineering Initiative for Patient Safety work system as a framework. Environmental service workers reported adequate cleaning supplies/equipment and displayed excellent knowledge of CDI hand hygiene requirements. Environmental service workers described current supervisory practices as providing an acceptable amount of time to clean CDI rooms, although other healthcare workers often pressured ESWs to clean rooms more quickly. Environmental service workers reported significant concern for CDI patients' family members as well as suggesting uncertainty regarding the need for family members to follow infection prevention practices. Small and cluttered patient rooms made cleaning tasks more difficult, and ESW cleaning tasks were often interrupted by other healthcare workers. Environmental service workers did not feel comfortable asking physicians for more time to finish cleaning a room nor did ESWs feel comfortable pointing out lapses in physician hand hygiene. Multiple work system components serve as barriers to and facilitators of ESW adherence to the nationally mandated Department of Veterans Affairs CDI bundle. Environmental service workers may represent an underappreciated resource for hospital infection prevention, and further efforts should be made to engage ESWs as members of the health care team.

Patients as educators: interprofessional learning for patient-centred care.

Patients with chronic conditions have unique expertise that enhances interprofessional education. Although their active involvement in education is increasing, patients have minimal roles in key educational tasks. A model that brings patients and students together for patient-centred learning, with faculty playing a supportive role, has been described in theory but not yet implemented. To identify issues involved in creating an educational intervention designed and delivered by patients and document outcomes. An advisory group of community members, students and faculty guided development of the intervention (interprofessional workshops). Community educators (CEs) were recruited through community organizations with a healthcare mandate. Workshops were planned by teams of key stakeholders, delivered by CEs, and evaluated by post-workshop student questionnaires. Workshops were delivered by CEs with epilepsy, arthritis, HIV/AIDS and two groups with mental health problems. Roles and responsibilities of planning team members that facilitated control by CEs were identified. Ten workshops attended by 142 students from 15 different disciplines were all highly rated. Workshop objectives defined by CEs and student learning both closely matched dimensions of patient-centredness. Our work demonstrates feasibility and impact of an educational intervention led by patient educators facilitated but not controlled by faculty.

To identify the functions that Volunteer Stroke Service (VSS) groups fulfil for their members. Qualitative focus group study. Mixed urban and rural community settings in Scotland. Seven focus groups comprising a total of 24 men and 14 women, with dysarthria or aphasia following stroke, who were members of VSS groups funded by Chest Heart and Stroke Scotland. We identified eight main themes. VSS groups (1) include members in an interpersonal network, (2) provide members with the opportunity to develop interpersonal relations, (3) provide members with support, (4) provide opportunities for personal growth and development, (5) supply members with a purpose, structure and routine, (6) help members establish and confirm their identify, beliefs and values, (7) help members accomplish individual and shared goals, and (8) provide members with the opportunity to influence others and be influenced. VSS groups appear to provide a range of functions that meet members' personal, interpersonal and psychological needs.

Household Size and the Decision to Purchase Health Insurance in Cambodia: Results of a Discrete-Choice Experiment with Scale Adjustment.

Ozawa, Sachiko; Grewal, Simrun; Bridges, John F P

2016-04-01

Community-based health insurance (CBHI) schemes have been introduced in low- and middle-income countries to increase health service utilization and provide financial protection from high healthcare expenditures. We assess the impact of household size on decisions to enroll in CBHI and demonstrate how to correct for group disparity in scale (i.e. variance differences). A discrete choice experiment was conducted across five CBHI attributes. Preferences were elicited through forced-choice paired comparison choice tasks designed based on D-efficiency. Differences in preferences were examined between small (1-4 family members) and large (5-12 members) households using conditional logistic regression. Swait and Louviere test was used to identify and correct for differences in scale. One-hundred and sixty households were surveyed in Northwest Cambodia. Increased insurance premium was associated with disutility [odds ratio (OR) 0.61, p < 0.01], while significant increase in utility was noted for higher hospital fee coverage (OR 10.58, p < 0.01), greater coverage of travel and meal costs (OR 4.08, p < 0.01), and more frequent communication with the insurer (OR 1.33, p < 0.01). While the magnitude of preference for hospital fee coverage appeared larger for the large household group (OR 14.15) compared to the small household group (OR 8.58), differences in scale were observed (p < 0.05). After adjusting for scale (k, ratio of scale between large to small household groups = 1.227, 95 % confidence interval 1.002-1.515), preference differences by household size became negligible. Differences in stated preferences may be due to scale, or variance differences between groups, rather than true variations in preference. Coverage of hospital fees, travel and meal costs are given significant weight in CBHI enrollment decisions regardless of household size. Understanding how community members make decisions about health insurance can inform low- and middle-income countries' paths towards universal health coverage.

2012-09-01

We describe a study to assess the bacteriological quality and safety of meat in Bodija market in Ibadan and to investigate the influence of gender and group membership on food safety. Mixed methods were used to gather information on meat safety and related socioeconomic factors. These methods included a participatory urban appraisal, focus group discussions with eight butchers' associations, in depth discussions with six key informants, a questionnaire study of 269 meat sellers and a cross-sectional survey of meat quality (200 samples from ten associations). We found that slaughter, processing and sale of beef meat take place under unhygienic conditions. The activities involve both men and women, with some task differentiation by gender. Meat sold by association members is of unacceptable quality. However, some groups have consistently better quality meat and this is positively correlated with the proportion of women members. Women also have significantly better food safety practice than men, though there was no significant difference in their knowledge of and attitude towards food safety. Most meat sellers (85 %) reported being ill in the last 2 weeks and 47 % reported experiencing gastrointestinal illness. Eating beef, eating chicken, eating offal, consuming one's own products and belonging to a group with poor quality of meat were all strong and significant predictors of self-reported gastrointestinal illness. We include that gender and group membership influence meat quality and self-reported gastrointestinal illness and that butchers' associations are promising entry points for interventions to improve food safety.

Good research practices for measuring drug costs in cost-effectiveness analyses: an international perspective: the ISPOR Drug Cost Task Force report--Part VI.

The pharmacoeconomic guidelines available in the literature or promulgated in many countries are either vague or silent about how drug costs should be established or measured so an international comparison of cost-effectiveness analysis (CEA) results can be made. The objective of this report is to provide guidance and recommendations on how drug costs should be measured for CEAs done from an internationally comparative perspective. Members of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) Task Force on Good Research Practices-Use of Drug Costs for Cost Effectiveness Analysis (Drug Cost Task Force [DCTF]) subgroup from several countries were experienced developers or users of CEA models, and worked in academia, industry, and as advisors to governments. They solicited comments on drafts from a core group of 174 external reviewers and more broadly, from the members of the ISPOR at the ISPOR 12th Annual International meeting and via the ISPOR Web site. Drug units should be standardized in terms of volume of active ingredient, regardless of packaging and dosing strength variations across countries. Drug costs should be measured in local currency per unit of active ingredient and should be converted to other currencies using sensitivity analyses of purchasing power parities (PPP) and exchange rates, whichever is more appropriate. When using drug prices from different years, the consumer price index for the local currency should be applied before the PPP and/or exchange rate conversion. CEA researchers conducting international pharmacoeconomic analysis should tailor the appropriate measure of drug costs to the international perspective, to maintain clarity and transparency on drug cost measurement in the context of international drug comparison and report the sensitivity of CEA results to reasonable cost conversions.

The use of source memory to identify one's own episodic confusion errors.

PubMed

Smith, S M; Tindell, D R; Pierce, B H; Gilliland, T R; Gerkens, D R

2001-03-01

In 4 category cued recall experiments, participants falsely recalled nonlist common members, a semantic confusion error. Errors were more likely if critical nonlist words were presented on an incidental task, causing source memory failures called episodic confusion errors. Participants could better identify the source of falsely recalled words if they had deeply processed the words on the incidental task. For deep but not shallow processing, participants could reliably include or exclude incidentally shown category members in recall. The illusion that critical items actually appeared on categorized lists was diminished but not eradicated when participants identified episodic confusion errors post hoc among their own recalled responses; participants often believed that critical items had been on both the incidental task and the study list. Improved source monitoring can potentially mitigate episodic (but not semantic) confusion errors.

In support of the new strategic plan, AGU has established a new task force to review, evaluate, and update the Union's policies on scientific misconduct and the process for investigating and responding to allegations of possible misconduct by AGU members. As noted by AGU president Michael McPhaden, "AGU can only realize its vision of `collaboratively advancing and communicating science and its power to ensure a sustainable future' if we have the trust of the public and policy makers. That trust is earned by maintaining the highest standards of scientific integrity in all that we do. The work of the Task Force on Scientific Ethics is essential for defining norms of professional conduct that all our members can aspire to and that demonstrate AGU's unwavering commitment to excellence in Earth and space science."

2013-12-01

To evaluate the effect of ergonomics training on non-ergonomists' ability to recognize and characterize the potential for musculoskeletal harm in manufacturing tasks. Ergonomics training was delivered to members of a participatory ergonomics team in a manufacturing facility. Before and after training, participatory ergonomics team members and the research team rated the potential for musculoskeletal harm for each of 30 tasks. Measures of agreement included Pearson, concordance, and intraclass correlation coefficients. Measures of agreement generally improved after training. The greatest agreement was observed for ratings of the potential for musculoskeletal harm to the low back. The greatest improvement in agreement was observed for ratings of the potential for musculoskeletal harm to the neck/shoulder. The training seemed to improve non-experts' ability to identify the potential for musculoskeletal harm.

Perspectives on bioanalytical mass spectrometry and automation in drug discovery.

PubMed

Janiszewski, John S; Liston, Theodore E; Cole, Mark J

2008-11-01

The use of high speed synthesis technologies has resulted in a steady increase in the number of new chemical entities active in the drug discovery research stream. Large organizations can have thousands of chemical entities in various stages of testing and evaluation across numerous projects on a weekly basis. Qualitative and quantitative measurements made using LC/MS are integrated throughout this process from early stage lead generation through candidate nomination. Nearly all analytical processes and procedures in modern research organizations are automated to some degree. This includes both hardware and software automation. In this review we discuss bioanalytical mass spectrometry and automation as components of the analytical chemistry infrastructure in pharma. Analytical chemists are presented as members of distinct groups with similar skillsets that build automated systems, manage test compounds, assays and reagents, and deliver data to project teams. The ADME-screening process in drug discovery is used as a model to highlight the relationships between analytical tasks in drug discovery. Emerging software and process automation tools are described that can potentially address gaps and link analytical chemistry related tasks. The role of analytical chemists and groups in modern 'industrialized' drug discovery is also discussed.

Organization's Orderly Interest Exploration: Inception, Development and Insights of AIAA's Topics Database

NASA Technical Reports Server (NTRS)

Marshall, Jospeh R.; Morris, Allan T.

2007-01-01

Since 2003, AIAA's Computer Systems and Software Systems Technical Committees (TCs) have developed a database that aids technical committee management to map technical topics to their members. This Topics/Interest (T/I) database grew out of a collection of charts and spreadsheets maintained by the TCs. Since its inception, the tool has evolved into a multi-dimensional database whose dimensions include the importance, interest and expertise of TC members and whether or not a member and/or a TC is actively involved with the topic. In 2005, the database was expanded to include the TCs in AIAA s Information Systems Group and then expanded further to include all AIAA TCs. It was field tested at an AIAA Technical Activities Committee (TAC) Workshop in early 2006 through live access by over 80 users. Through the use of the topics database, TC and program committee (PC) members can accomplish relevant tasks such as: to identify topic experts (for Aerospace America articles or external contacts), to determine the interest of its members, to identify overlapping topics between diverse TCs and PCs, to guide new member drives and to reveal emerging topics. This paper will describe the origins, inception, initial development, field test and current version of the tool as well as elucidate the benefits and insights gained by using the database to aid the management of various TC functions. Suggestions will be provided to guide future development of the database for the purpose of providing dynamics and system level benefits to AIAA that currently do not exist in any technical organization.

Management-related issues are an important aspect of monitoring asthma in children in clinical practice. This review summarises the literature on practical aspects of monitoring including adherence to treatment, inhalation technique, ongoing exposure to allergens and irritants, comorbid conditions and side-effects of treatment, as agreed by the European Respiratory Society Task Force on Monitoring Asthma in Childhood. The evidence indicates that it is important to discuss adherence to treatment in a non-confrontational way at every clinic visit, and take into account a patient's illness and medication beliefs. All task force members teach inhalation techniques at least twice when introducing a new inhalation device and then at least annually. Exposure to second-hand tobacco smoke, combustion-derived air pollutants, house dust mites, fungal spores, pollens and pet dander deserve regular attention during follow-up according to most task force members. In addition, allergic rhinitis should be considered as a cause for poor asthma control. Task force members do not screen for gastro-oesophageal reflux and food allergy. Height and weight are generally measured at least annually to identify individuals who are susceptible to adrenal suppression and to calculate body mass index, even though causality between obesity and asthma has not been established. In cases of poor asthma control, before stepping up treatment the above aspects of monitoring deserve closer attention. Copyright ©ERS 2015.

Fluctuations of the experience of togetherness within the team over time: task-cohesion and shared understanding throughout a sporting regular season.

Bourbousson, Jérôme; Fortes-Bourbousson, Marina

2017-06-01

Based on a diagnosis action research design, the present study assessed the fluctuations of the team experience of togetherness. Reported experiences of 12 basketball team members playing in the under-18 years old national championship were studied during a four-month training and competitive period. Time series analysis (Auto-Regressive Integrated Moving Average procedures) served to describe temporal properties of the way in which the fluctuations of task-cohesion and shared understanding were step-by-step experienced over time, respectively. Correlations, running-correlations and cross-lagged correlations were used to describe the temporal links that governed the relationships between both phenomena. The results indicated that the task-cohesion dimensions differed mainly for shared understanding dynamics in that their time fluctuations were not embedded in external events, and that the variations in shared understanding tend to precede 'individual attractions to the task' variations with seven team practical sessions. This study argues for further investigation of how 'togetherness' is experienced alternatively as a feeling of cohesion or shared understanding. Practitioner Summary: The present action research study investigated the experience that the team members have to share information during practice, and the subsequent benefices on team cohesion. Results call for specific interventions that make team members accept the fluctuating nature of team phenomena, to help them maintaining their daily efforts.

Summary Background and objectives Web-based technology is critical to the future of healthcare. As part of the Safe Kidney Care cohort study evaluating patient safety in CKD, this study determined how effectively a representative sample of patients with CKD or family members could interpret and use the Safe Kidney Care website (www.safekidneycare.org), an informational website on safety in CKD. Design, setting, participants, & measurements Between November of 2011 and January of 2012, persons with CKD or their family members underwent formal usability testing administered by a single interviewer with a second recording observer. Each participant was independently provided a list of 21 tasks to complete, with each task rated as either easily completed/noncritical error or critical error (user cannot complete the task without significant interviewer intervention). Results Twelve participants completed formal usability testing. Median completion time for all tasks was 17.5 minutes (range=10–44 minutes). In total, 10 participants had greater than or equal to one critical error. There were 55 critical errors in 252 tasks (22%), with the highest proportion of critical errors occurring when participants were asked to find information on treatments that may damage kidneys, find the website on the internet, increase font size, and scroll to the bottom of the webpage. Participants were generally satisfied with the content and usability of the website. Conclusions Web-based educational materials for patients with CKD should target a wide range of computer literacy levels and anticipate variability in competency in use of the computer and internet.

Conflict in medical teams: opportunity or danger?

PubMed

Greer, Lindred L; Saygi, Ozum; Aaldering, Hillie; de Dreu, Carsten K W

2012-10-01

  Intragroup conflicts often occur when people are called upon to collaborate in the accomplishment of a task. For example, when surgeons and nurses work together during an operation, conflicts may emerge because of differences in functional understanding. Whether these conflicts are beneficial or detrimental to team outcomes has been the source of much debate. From one perspective, a conflict that stems from differences in members' functional understanding may enhance team members' understanding and performance of the task at hand. By contrast, such a conflict may cause hostility, emotionality and distraction from actual task accomplishment.   This study reviews findings on the relationships between intragroup conflict and team outcomes, discusses potential conflict resolution strategies for intragroup conflicts and explores how these link to the field of medical education.   Three primary types of conflict have been distinguished, involving, respectively, task-, process- and relationship-associated conflict. Both process conflict, or conflict about the logistics of task accomplishment, and relationship conflict, or conflict about interpersonal incompatibilities, have been shown to detract from effective team functioning. Task conflict, or conflict about the content of the task itself, is also generally negative for team functioning, but under certain conditions its negative effects may be minimised. For example, when teams can clearly separate task issues from relationship issues, task conflicts are less destructive for team outcomes. However, achieving such a separation in practice, and thereby realising the benefits of task conflict, is quite difficult to achieve.   Intragroup conflicts pose a challenge to effective team functioning. In the education of medical professionals, effective training in conflict management skills and their application to specific team conflict dynamics, such as with reference to how to resolve task as opposed to relationship conflict, is critical. © Blackwell Publishing Ltd 2012.

The Wallpaper Effect: The Contact Hypothesis Fails for Minority Group Members Who Live in Areas with a High Proportion of Majority Group Members

PubMed Central

Barlow, Fiona Kate; Hornsey, Matthew J.; Thai, Michael; Sengupta, Nikhil K.; Sibley, Chris G.

2013-01-01

We aim to provide one explanation for why the link between contact and prejudice is consistently less strong for minority group members than it is for majority group members. Specifically, we propose a “wallpaper effect” such that contact works to increase minority group members' positivity towards majority groups when they live in areas densely populated with other minority group members. Conversely, we suggest that when minority group members live in neighborhoods patterned with majority group faces (as is so often the case), contact will be less transformative. We test this assumption using a large sample of both New Zealander minority (Māori; N = 925) and majority (European; N = 3805) group members. In line with predictions, Māori who lived in minority dense neighborhoods showed the traditional association between contact and increased warmth towards New Zealander Europeans. This relationship, however, was weak or non-existent when they lived in primarily European neighborhoods. Contact effects in majority group members were unaffected by neighborhood composition. The interaction held when controlling for, and was not explained by: gender, income, experiences of harm, cognitions of race-based rejection, or realistic threat. We provide the first evidence to suggest that when it comes to minority group members' intergroup attitudes, contact with majority group members may be a relatively ineffective predictor unless the “wallpaper” of their lives is minority-dense.

Few educational interventions have been developed to teach Family Meeting (FM) communication skills at the undergraduate level. We developed an innovative curriculum to address this gap. Fourth year medical students during 2011-2013 (n = 674) completed training for conducting a FM. To assess the effectiveness of this training, students completed a FM Objective Structured Clinical Exam (OSCE) that included 15 domains rated on a 1-5 point Likert scale. Tasks included discussing prognosis, establishing goals of care and demonstrating conflict resolution skills. Students received one-to-one feedback from standardized family members and faculty observers. Group debriefings with faculty were held after the OSCE. Analysis of faculty feedback narratives revealed four themes in which students required improvement: 1) Discussing prognosis, 2) Explaining palliative care/hospice, 3) Avoiding medical jargon, and 4) Discussing cultural/religious preferences. Evaluation total mean score was 28.2 (Min 15, Max 63; SD 7.57), and identified student's need to; 1) Ask more about the degree of knowledge family members want, 2) Ask religious beliefs, and 3) Assess family members' level of education ( p < 0.001). Qualitative analysis of group debriefings suggested that student perception of the OSCE experience was positive overall. Students found the case to be realistic and immediate feedback to be helpful. Conducting a FM is an advanced skill. This study shows that it is possible to train fourth year students to lead FMs and identify their strengths, needs using a FM OSCE.

Response to Vogelstein: How the 2012 AAP Task Force on circumcision went wrong.

PubMed

Van Howe, Robert S

2018-01-01

Vogelstein cautions medical organizations against jumping into the fray of controversial issues, yet proffers the 2012 American Academy of Pediatrics' Task Force policy position on infant male circumcision as 'an appropriate use of position-statements.' Only a scratch below the surface of this policy statement uncovers the Task Force's failure to consider Vogelstein's many caveats. The Task Force supported the cultural practice by putting undeserved emphasis on questionable scientific data, while ignoring or underplaying the importance of valid contrary scientific data. Without any effort to quantitatively assess the risk/benefit balance, the Task Force concluded the benefits of circumcision outweighed the risks, while acknowledging that the incidence of risks was unknown. This Task Force differed from other Academy policy-forming panels by ignoring the Academy's standard quality measures and by not appointing members with extensive research experience, extensive publications, or recognized expertise directly related to this topic. Despite nearly 100 publications available at the time addressing the substantial ethical issues associated with infant male circumcision, the Task Force chose to ignore the ethical controversy. They merely stated, with minimal justification, the opinion of one of the Task Force members that the practice of infant male circumcision is morally permissible. The release of the report has fostered an explosion of academic discussion on the ethics of infant male circumcision with a number of national medical organizations now decrying the practice as a human rights violation. © 2017 John Wiley & Sons Ltd.

Allington, Ruth; Fernandez-Fuentes, Isabel

2013-04-01

A new IUGS Task Group entitled the Task Group on Global Geoscience Professionalism was formed in 2012 and launched at a symposium at the 341GC in Brisbane on strengthening communication between fundamental and applied geosciences and between geoscientists and public. The Task Group aims to ensure that the international geoscience community is engaged in a transformation of its profession so as to embed the need for a professional skills base alongside technical and scientific skills and expertise, within a sound ethical framework in all arenas of geoscience practice. This needs to be established during training and education and reinforced as CPD throughout a career in geoscience as part of ensuring public safety and effective communication of geoscience concepts to the public. The specific objective of the Task Group on Global Geoscience Professionalism that is relevant to this poster session is: • To facilitate a more 'joined up' geoscience community fostering better appreciation by academics and teachers of the professional skills that geoscientists need in the workplace, and facilitate better communication between academic and applied communities leading to more effective application of research findings and technology to applied practitioners and development of research programmes that truly address urgent issues. Other Task Group objectives are: • To provide a specific international forum for discussion of matters of common concern and interest among geoscientists and geoscientific organizations involved in professional affairs, at the local, national and international level; • To act as a resource to IUGS on professional affairs in the geosciences as they may influence and impact "Earth Science for the Global Community" in general - both now and in the future; • To offer and provide leadership and knowledge transfer services to countries and geoscientist communities around the world seeking to introduce systems of professional governance and self-regulation in the Earth sciences; • To provide geoscientists in all areas of professional practice and at all stages of their careers with practical guidance and support on professional matters; • To continue and increase over time the provision of symposia and technical sessions to allow for exchange and knowledge transfer at IGCs and other events for those involved in, and impacted by, the evolution of professionalism in the geosciences. • To act as a resource to members of IUGS, and others, of material and speakers to present to geoscience groups - in particular young Earth scientists - around the world on professional practice and registration matters (including geoscience practice standards and guidelines, and reporting standards, codes of ethics and conduct, and professional registration.) The sponsors of the new TG are: • European Federation of Geologists (EFG) • Geoscientists Canada • American Institute of Professional Geologists (AIPG) • Australian Institute of Geoscientists (AIG) • South African Council for Natural Scientific Professions (SACNSP) • El Colegio de Geólogos de Bolivia (College of Geologists of Bolivia)

The Association of Academic Physiatrists (AAP) convened a women's task force in 2016, and the members agreed on a list of metrics that would permit retrospective data review pertaining to the representation and inclusion of women physicians in the society. Examples of categories examined included leadership positions (i.e., board membership, board presidents, committee membership, committee chairs, and resident fellow physician chairs), conference presentations (i.e., annual meeting session proposals, annual meeting faculty, annual meeting plenary speakers) and recognition awards (i.e., recognition award nominations and recipients). The findings highlight areas in which the AAP has been successful in supporting gender equity and other areas in which women physiatrists have been underrepresented. The task force worked with the Board of Trustees to construct an action plan; asking the respective committees to address areas of underrepresentation. A volunteer from each committee was deemed a 'diversity steward' and going forward will work directly with the task force as a liaison to document an action plan and collect data. The board plans to transparently report progress to members and other stakeholders, and the task force aims to publish a follow-up report within the next five years.

Practice analysis of chiropractic radiology: identifying items for part I of the clinical competency examination.

Smith, Sara Dawn; Beran, Tanya N

2012-01-01

The purpose of this study was to describe the current scope of practice of chiropractic radiologists by identifying frequent tasks conducted as well as those conditions most often seen and those that present the greatest risk of harm to patients. A mixed-methods approach was used. An online survey was conducted with 91 diplomates listed with the American Chiropractic Board of Radiology. Participants rated the frequency of tasks they perform and conditions they see on a 5-point scale from "never" to "daily." They also rated the level of risk each condition presents to patients on a 5-point scale from "no risk" to "severe risk." Frequency and risk ratings were then presented in rank order to 22 subject matter experts at 3 focus groups. The most frequent task reported was writing radiology reports (mean [SD], 4.29 [1.58]). Ratings of the frequency of conditions seen in practice and the risk they present to patients were ranked from the highest to lowest for frequency and risk separately. The most frequent conditions seen were reportedly those with structural or joint derangement; the highest risk conditions seen are those that are systemic. Focus group members recommended that some conditions receive higher rankings and that certain conditions be recategorized for future practice analyses. This study helps to define the current scope of practice of chiropractic radiologists and identify frequent tasks and conditions. These results inform the development of a new test outline for Part I of the chiropractic radiology certification examination to ensure that examinees are tested on the most important conditions chiropractic radiologists see in practice.

Lykes, M B; Brabeck, M M; Ferns, T; Radan, A

1993-12-01

The Task Force of the American Psychological Association Division 35, Psychology of Women, conducted a literature review of resources from Latin America to examine the social dimensions of state-sponsored violence in Latin America, their effects on socialization and community, and some responses of women surviving these experiences. It limited its review to works of women's groups, progressive organizations, and individual women exploring the effects of war and state-sponsored violence on women's mental health. Recurring emergent themes included the false dichotomy of violence committed against women in public versus that committed in private, silencing of women accompanies state imposed terror, collective resistance to such terror. The resources addressed 3 types of women's experiences of violence: exile within and beyond one's national borders; torture--an extreme form of state-sponsored violence; and nontraditional, culturally appropriate interventions--alternatives to Western models. This review motivated the Task Force to call on their colleagues to contribute to the on-going documentation of state-sponsored violence. Task Force members identified several areas for collaborative research and/or theory development. Psychologists should question the validity of clinical neutrality and examine the particular meanings of non-neutrality within different cultures. For example, some Latin American psychologists reject diagnoses of intrapsychic syndromes (e.g., post-traumatic stress syndrome) and propose concepts that center on the nexus of individuals and social life. The Task Force sees great opportunities for US psychologists to network and to form solidarity-based relationships with Latin American women. It has identified many women's groups working in Latin America. Human rights organizations (e.g., Americas Watch) have formed women's projects. Further work should be done to improve resource exchanges.

Plan for conducting an international machine tool task force

The basic objectives of the Machine Tool Task Force (MTTF) are to characterize and summarize the state of the art of cutting machine tool technology and to identify promising areas of future R and D. These goals will be accomplished with a series of multidisciplinary teams of prominent experts and individuals experienced in the specialized technologies of machine tools or in the management of machine tool operations. Experts will be drawn from all areas of the machine tool community: machine tool users or buyer organizations, builders, and R and D establishments including universities and government laboratories, both domestic and foreign.more » A plan for accomplishing this task is presented. The area of machine tool technology has been divided into about two dozen technology subjects on which teams of one or more experts will work. These teams are, in turn, organized into four principal working groups dealing, respectively, with machine tool accuracy, mechanics, control, and management systems/utilization. Details are presented on specific subjects to be covered, the organization of the Task Force and its four working groups, and the basic approach to determining the state of the art of technology and the future directions of this technology. The planned review procedure, the potential benefits, our management approach, and the schedule, as well as the key participating personnel and their background are discussed. The initial meeting of MTTF members will be held at a plenary session on October 16 and 17, 1978, in Scottsdale, AZ. The MTTF study will culminate in a conference on September 1, 1980, in Chicago, IL, immediately preceeding the 1980 International Machine Tool Show. At this time, our results will be released to the public; a series of reports will be published in late 1980.« less

Effects of dual-task training on balance and executive functions in Parkinson's disease: A pilot study.

Fernandes, Ângela; Rocha, Nuno; Santos, Rubim; Tavares, João Manuel R S

2015-01-01

The aim of this study was to analyze the efficacy of cognitive-motor dual-task training compared with single-task training on balance and executive functions in individuals with Parkinson's disease. Fifteen subjects, aged between 39 and 75 years old, were randomly assigned to the dual-task training group (n = 8) and single-task training group (n = 7). The training was run twice a week for 6 weeks. The single-task group received balance training and the dual-task group performed cognitive tasks simultaneously with the balance training. There were no significant differences between the two groups at baseline. After the intervention, the results for mediolateral sway with eyes closed were significantly better for the dual-task group and anteroposterior sway with eyes closed was significantly better for the single-task group. The results suggest superior outcomes for the dual-task training compared to the single-task training for static postural control, except in anteroposterior sway with eyes closed.

Locating overlapping dense subgraphs in gene (protein) association networks and predicting novel protein functional groups among these subgraphs

Most tasks in a cell are performed not by individual proteins, but by functional groups of proteins (either physically interacting with each other or associated in other ways). In gene (protein) association networks these groups show up as sets of densely connected nodes. In the yeast, Saccharomyces cerevisiae, known physically interacting groups of proteins (called protein complexes) strongly overlap: the total number of proteins contained by these complexes by far underestimates the sum of their sizes (2750 vs. 8932). Thus, most functional groups of proteins, both physically interacting and other, are likely to share many of their members with other groups. However, current algorithms searching for dense groups of nodes in networks usually exclude overlaps. With the aim to discover both novel functions of individual proteins and novel protein functional groups we combine in protein association networks (i) a search for overlapping dense subgraphs based on the Clique Percolation Method (CPM) (Palla, G., et.al. Nature 435, 814-818 (2005), http://angel.elte.hu/clustering), which explicitly allows for overlaps among the groups, and (ii) a verification and characterization of the identified groups of nodes (proteins) with the help of standard annotation databases listing known functions.

Developing the nuclear idea: concept, technique, and process.

PubMed

Billow, Richard M

2013-10-01

I introduce an approach to group that has remained undeveloped in the literature, but represents an essence of relationally oriented group psychotherapy. Evolving from the verbalizations and enactments through which the group symbolizes and becomes known-a nuclear idea takes shape. It emerges from the nucleus of the group process: co-created from intersubjective forces and locations that cannot be fully specified, yet may be possible to observe, name, and utilize clinically. Groups organize themselves by developing nuclear ideas, with the therapist's active participation. They are vehicles through which a group comes to think about its thinking: not only what it thinks, but also how it thinks, or chooses not to think, and when and why. Developing the nuclear idea provides a framework for how the therapist-and the group itself-goes about the task of containing. With its emphasis on meaning and the development of meaning as transformational, the concept of the nuclear idea supplements the whole group, interpersonal, and intrapsychic lenses through which the therapist comes to understand group experience and base interventions. Clinical vignettes illustrate how the therapist may develop nuclear ideas thematically, conceptualize further, and negotiate meaning with the co-participation of other group members.

To formulate clinical practice guidelines for hormonal replacement in hypopituitarism in adults. The participants include an Endocrine Society-appointed Task Force of six experts, a methodologist, and a medical writer. The American Association for Clinical Chemistry, the Pituitary Society, and the European Society of Endocrinology co-sponsored this guideline. The Task Force developed this evidence-based guideline using the Grading of Recommendations, Assessment, Development, and Evaluation system to describe the strength of recommendations and the quality of evidence. The Task Force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies. One group meeting, several conference calls, and e-mail communications enabled consensus. Committees and members of the Endocrine Society, the American Association for Clinical Chemistry, the Pituitary Society, and the European Society of Endocrinology reviewed and commented on preliminary drafts of these guidelines. Using an evidence-based approach, this guideline addresses important clinical issues regarding the evaluation and management of hypopituitarism in adults, including appropriate biochemical assessments, specific therapeutic decisions to decrease the risk of co-morbidities due to hormonal over-replacement or under-replacement, and managing hypopituitarism during pregnancy, pituitary surgery, and other types of surgeries.

Oppositional identities: dissimilarities in how women and men experience parent versus professional roles.

PubMed

Hodges, Allegra J; Park, Bernadette

2013-08-01

As stereotypes of social groups undergo change, group members gain access to previously denied social and cultural roles. Although such access is desirable, to the extent that the behavior, traits, and attitudes required to succeed in a new role are in opposition to those required to do well in a still-valued old role, conflict in the self-concept may ensue. Specifically, the individual must necessarily fall short in social comparisons of the self to the ideal group member in 1 or both roles, threatening self-integrity. Examining the specific case of oppositional identities between career and mom roles, we argue that women respond to this conflict by shifting back and forth between activation of whichever identity is relevant in a given situational context in a way that men do not. This shifting of self-associations is hypothesized to deplete scarce cognitive resources, interfering with performance on a task that requires executive function capacity. In addition, to the extent the identities are viewed as trading off against one another, failure in 1 domain may be responded to by activating the alternate identity in an effort to restore self-integrity, again in a way that is not true for men. These hypotheses are explored across 4 studies, utilizing both college students in the midst of formulating--and working parents in the midst of negotiating--these identities.

Team cognition is an important factor in evaluating and determining team performance. Forming a team with good shared cognition is even more crucial for laparoscopic surgery applications. In this study, we analyzed the eye tracking data of two surgeons during a laparoscopic simulation operation, then performed Cross Recurrence Analysis (CRA) on the recorded data to study the delay behaviour for good performer and poor performer teams. Dual eye tracking data for twenty two dyad teams were recorded during a laparoscopic task and then the teams were divided into good performer and poor performer teams based on the task times. Eventually we studied the delay between two team members for good and poor performer teams. The results indicated that the good performer teams show a smaller delay comparing to poor performer teams. This study is compatible with gaze overlap analysis between team members and therefore it is a good evidence of shared cognition between team members.

Rasker, P C; Post, W M; Schraagen, J M

2000-08-01

In two studies, the effect of two types of intra-team feedback on developing a shared mental model in Command & Control teams was investigated. A distinction is made between performance monitoring and team self-correction. Performance monitoring is the ability of team members to monitor each other's task execution and give feedback during task execution. Team self-correction is the process in which team members engage in evaluating their performance and in determining their strategies after task execution. In two experiments the opportunity to engage in performance monitoring, respectively team self-correction, was varied systematically. Both performance monitoring as well as team self-correction appeared beneficial in the improvement of team performance. Teams that had the opportunity to engage in performance monitoring, however, performed better than teams that had the opportunity to engage in team self-correction.

Mentoring of junior faculty members continues to be a widespread need in academic pharmacy in both new programs and established schools. The American Association of Colleges of Pharmacy (AACP) Joint Council Task Force on Mentoring was charged with gathering information from member colleges and schools and from the literature to determine best practices that could be shared with the academy. The task force summarized their findings regarding the needs and responsibilities for mentors and protégés at all faculty levels; what mentoring pieces are in existence, which need improvement, and which need to be created; and how effective mentoring is defined and could be measured. Based on these findings, the task force developed several recommendations as well as the PAIRS Faculty Mentorship Checklist. Academic institutions can benefit from the checklist whether they are planning to implement a faculty mentorship program or are interested in modifying existing programs. PMID:24954938

Collaborative, case-based learning: how do students actually learn from each other?

PubMed

Thurman, Joanne; Volet, Simone E; Bolton, John R

2009-01-01

The value of collaborative, case-based, and problem-based learning has received increased attention in recent years. Several studies have documented veterinary staff and students' generally positive feedback on group learning activities, but one largely unaddressed question is how students actually learn from each other. This study examined how second-year veterinary students learned from each other during a collaborative, case-based learning project. Data were students' written reflections on their learning in the veterinary course and the specific learning experience, and a matched pre- and post-task questionnaire. Consistent with prior research describing veterinary students as individualistic learners, only a third of students spontaneously mentioned learning from each other as one of their most effective strategies. However, when prompted to describe a time when they felt that group members were really learning from each other, students reported highly valuable collaborative learning processes, which they explicitly linked to learning and understanding benefits. Questionnaire data were consistent, showing that students became more positive toward several aspects of the activity as well as toward group work in general. One unexpected finding was the lack of a relationship between students' self-evaluation of their learning and how well group members knew each other. These findings provide strong support for the educational value of collaborative, case-based learning. In light of other research evidence (using observation data) that the amount of time students actually engage in high-level collaborative processes may be rather limited, this article points to the need for veterinary teachers to better prepare students for group learning activities.

Ant-like task allocation and recruitment in cooperative robots

Krieger, Michael J. B.; Billeter, Jean-Bernard; Keller, Laurent

2000-08-01

One of the greatest challenges in robotics is to create machines that are able to interact with unpredictable environments in real time. A possible solution may be to use swarms of robots behaving in a self-organized manner, similar to workers in an ant colony. Efficient mechanisms of division of labour, in particular series-parallel operation and transfer of information among group members, are key components of the tremendous ecological success of ants. Here we show that the general principles regulating division of labour in ant colonies indeed allow the design of flexible, robust and effective robotic systems. Groups of robots using ant-inspired algorithms of decentralized control techniques foraged more efficiently and maintained higher levels of group energy than single robots. But the benefits of group living decreased in larger groups, most probably because of interference during foraging. Intriguingly, a similar relationship between group size and efficiency has been documented in social insects. Moreover, when food items were clustered, groups where robots could recruit other robots in an ant-like manner were more efficient than groups without information transfer, suggesting that group dynamics of swarms of robots may follow rules similar to those governing social insects.

Social Groups Prioritize Selective Attention to Faces: How Social Identity Shapes Distractor Interference

Human faces automatically attract visual attention and this process appears to be guided by social group memberships. In two experiments, we examined how social groups guide selective attention toward in-group and out-group faces. Black and White participants detected a target letter among letter strings superimposed on faces (Experiment 1). White participants were less accurate on trials with racial out-group (Black) compared to in-group (White) distractor faces. Likewise, Black participants were less accurate on trials with racial out-group (White) compared to in-group (Black) distractor faces. However, this pattern of out-group bias was only evident under high perceptual load—when the task was visually difficult. To examine the malleability of this pattern of racial bias, a separate sample of participants were assigned to mixed-race minimal groups (Experiment 2). Participants assigned to groups were less accurate on trials with their minimal in-group members compared to minimal out-group distractor faces, regardless of race. Again, this pattern of out-group bias was only evident under high perceptual load. Taken together, these results suggest that social identity guides selective attention toward motivationally relevant social groups—shifting from out-group bias in the domain of race to in-group bias in the domain of minimal groups—when perceptual resources are scarce.

Native Amazonian children forego egalitarianism in merit-based tasks when they learn to count.

Cooperation often results in a final material resource that must be shared, but deciding how to distribute that resource is not straightforward. A distribution could count as fair if all members receive an equal reward (egalitarian distributions), or if each member's reward is proportional to their merit (merit-based distributions). Here, we propose that the acquisition of numerical concepts influences how we reason about fairness. We explore this possibility in the Tsimane', a farming-foraging group who live in the Bolivian rainforest. The Tsimane' learn to count in the same way children from industrialized countries do, but at a delayed and more variable timeline, allowing us to de-confound number knowledge from age and years in school. We find that Tsimane' children who can count produce merit-based distributions, while children who cannot count produce both merit-based and egalitarian distributions. Our findings establish that the ability to count - a non-universal, language-dependent, cultural invention - can influence social cognition. © 2015 John Wiley & Sons Ltd.

Since long ago the nurse has become more concerned about the delivery of care for patients with chronic and degeneratives diseases. Nevertheless, the accomplishment of this task is not an easy one. Moreover, when the patient reaches the final stage. Usually this patient experiences emotional and physical alteration. The family is deeply involved in this process and generally they seek nurses help because they are the closest ones to the patient and his/her family. When the patient go trough this dramatic acute change in health condition or in face of chronic degenerative or final stage disease is made, the relationship with the family becomes more difficult demanding nursing intervention. The objective of this study is to report the experience of nurse's participation in the implantation and development of multidisciplinary group for treatment of chronical and final stage patients. This group has been working for two years and has had good results. This group has worked treatment schemes for treatment used by all members of multidisciplinary team. From previous experiences, we knew that there is always a discrepancy between the information given by professional and friends and relatives ones. Which could increase fear and anxiety the reassurance given by the health team, a fair distribution of tasks and the information delivery to the patient proved to be successful.

The aim was to formulate clinical practice guidelines for acromegaly. The Task Force included a chair selected by the Endocrine Society Clinical Guidelines Subcommittee (CGS), five experts in the field, and a methodologist. The authors received no corporate funding or remuneration. This guideline is cosponsored by the European Society of Endocrinology. This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to describe both the strength of recommendations and the quality of evidence. The Task Force reviewed primary evidence and commissioned two additional systematic reviews. One group meeting, several conference calls, and e-mail communications enabled consensus. Committees and members of the Endocrine Society and the European Society of Endocrinology reviewed drafts of the guidelines. Using an evidence-based approach, this acromegaly guideline addresses important clinical issues regarding the evaluation and management of acromegaly, including the appropriate biochemical assessment, a therapeutic algorithm, including use of medical monotherapy or combination therapy, and management during pregnancy.

Facial Comparison from CCTV footage: The competence and confidence of the jury.

PubMed

Walker, Heather; Tough, Ann

2015-12-01

CCTV footage is commonly used in the court room to help visualise the crime in question and to help identify the offender. Unfortunately the majority of surveillance cameras produce such poor quality images that the task of identifying individuals can be extremely difficult. This study aimed at determining whether the task of identifying the offender in CCTV footage was one which a jury should be competent to do, or whether expert evidence would be beneficial in such cases. The ability of potential jury members, the general public, was tested by asking participants to play the role of a jury member by means of an online survey. Potential jury members viewed CCTV in which a simulated offence took place, and were subsequently asked to compare still images of a defendant to the offender to try to determine if they were competent and confident about making a judgement as to whether the defendant committed the crime. Factors such as age, gender and profession of the potential jury members were considered, as well as the type of crime committed, in order to establish if these play any role in the decision made by potential jury members. These factors did not appear to play a significant role; however confidence was also investigated and it became very evident that this was a factor that must be taken into consideration when determining the requirement for expert contribution in facial comparisons. Jury members may well be willing and competent to a basic level in carrying out a facial comparison but if they lack a certain level of confidence in their ability and decision making then this task is more suitable for an expert with experience and skills in this field.

Skin self-examinations and visual identification of atypical nevi: comparing individual and crowdsourcing approaches.

PubMed

King, Andy J; Gehl, Robert W; Grossman, Douglas; Jensen, Jakob D

2013-12-01

Skin self-examination (SSE) is one method for identifying atypical nevi among members of the general public. Unfortunately, past research has shown that SSE has low sensitivity in detecting atypical nevi. The current study investigates whether crowdsourcing (collective effort) can improve SSE identification accuracy. Collective effort is potentially useful for improving people's visual identification of atypical nevi during SSE because, even when a single person has low reliability at a task, the pattern of the group can overcome the limitations of each individual. Adults (N=500) were recruited from a shopping mall in the Midwest. Participants viewed educational pamphlets about SSE and then completed a mole identification task. For the task, participants were asked to circle mole images that appeared atypical. Forty nevi images were provided; nine of the images were of nevi that were later diagnosed as melanoma. Consistent with past research, individual effort exhibited modest sensitivity (.58) for identifying atypical nevi in the mole identification task. As predicted, collective effort overcame the limitations of individual effort. Specifically, a 19% collective effort identification threshold exhibited superior sensitivity (.90). The results of the current study suggest that limitations of SSE can be countered by collective effort, a finding that supports the pursuit of interventions promoting early melanoma detection that contain crowdsourced visual identification components.

Integrated data lookup and replication scheme in mobile ad hoc networks

NASA Astrophysics Data System (ADS)

Chen, Kai; Nahrstedt, Klara

2001-11-01

Accessing remote data is a challenging task in mobile ad hoc networks. Two problems have to be solved: (1) how to learn about available data in the network; and (2) how to access desired data even when the original copy of the data is unreachable. In this paper, we develop an integrated data lookup and replication scheme to solve these problems. In our scheme, a group of mobile nodes collectively host a set of data to improve data accessibility for all members of the group. They exchange data availability information by broadcasting advertising (ad) messages to the group using an adaptive sending rate policy. The ad messages are used by other nodes to derive a local data lookup table, and to reduce data redundancy within a connected group. Our data replication scheme predicts group partitioning based on each node's current location and movement patterns, and replicates data to other partitions before partitioning occurs. Our simulations show that data availability information can quickly propagate throughout the network, and that the successful data access ratio of each node is significantly improved.

Socialisation scheme with a high staff-patient ratio.

1981-01-01

Six months after a comprehensive socialisation scheme began, a prospective controlled study was carried out. The patients were tested in three practical sections - Cooking; Maintenance of Home and Clothing; Other Skills (eg. form-filling); and with a Questionnaire. Forty-eight members of an experimental group received socialisation training after initial testing. They and the 20 controls who did not undergo training were re-evaluated three months later. There was no significant difference between the groups in their initial scores. On retesting, the experimental group showed a significant improvement in Cooking (p less than 0.001), Home Maintenance (p less than 0.001) and the Questionnaire (p less than 0.05). Analysis of the inter-group differences showed significant superiority of the experimental group in Cooking (p less than 0.05) and Home Maintenance (p less than 0.05). It is suggested that such a socialisation scheme be considered for inclusion alongside other rehabilitation services in psychiatric hospitals. The emphasis on a high staff-to-patient ratio and the breakdown of each task into smaller steps emerged as essential elements in the training programme.

Introduction The authors examined the time that medical librarians spent on specific tasks for systematic reviews (SRs): interview process, search strategy development, search strategy translation, documentation, deliverables, search methodology writing, and instruction. We also investigated relationships among the time spent on SR tasks, years of experience, and number of completed SRs to gain a better understanding of the time spent on SR tasks from time, staffing, and project management perspectives. Methods A confidential survey and study description were sent to medical library directors who were members of the Association of Academic Health Sciences Libraries as well as librarians serving members of the Association of American Medical Colleges or American Osteopathic Association. Results Of the 185 participants, 143 (77%) had worked on an SR within the last 5 years. The number of SRs conducted by participants during their careers ranged from 1 to 500, with a median of 5. The major component of time spent was on search strategy development and translation. Average aggregated time for standard tasks was 26.9 hours, with a median of 18.5 hours. Task time was unrelated to the number of SRs but was positively correlated with years of SR experience. Conclusion The time required to conduct the librarian’s discrete tasks in an SR varies substantially, and there are no standard time frames. Librarians with more SR experience spent more time on instruction and interviews; time spent on all other tasks varied widely. Librarians also can expect to spend a significant amount of their time on search strategy development, translation, and writing. PMID:29632442

Keeping up appearances: Strategic information exchange by disidentified group members

PubMed Central

Matschke, Christina

2017-01-01

Information exchange is a crucial process in groups, but to date, no one has systematically examined how a group member’s relationship with a group can undermine this process. The current research examined whether disidentified group members (i.e., members who have a negative relationship with their group) strategically undermine the group outcome in information exchange. Disidentification has been found to predict negative group-directed behaviour, but at the same time disidentified members run the risk of being punished or excluded from the group when displaying destructive behaviour. In three studies we expected and found that disidentified group members subtly act against the interest of the group by withholding important private information, while at the same time they keep up appearances by sharing important information that is already known by the other group members. These findings stress the importance of taking a group member’s relationship with a group into account when considering the process of information exchange. PMID:28384322

2017-01-01

The authors investigated whether working memory training improves motor-motor dual-task performance consisted of upper and lower limb tasks. The upper limb task was a simple reaction task and the lower limb task was an isometric knee extension task. 45 participants (age = 21.8 ± 1.6 years) were classified into a working memory training group (WM-TRG), dual-task training group, or control group. The training duration was 2 weeks (15 min, 4 times/week). Our results indicated that working memory capacity increased significantly only in the WM-TRG. Dual-task performance improved in the WM-TRG and dual-task training group. Our study provides the novel insight that working memory training improves dual-task performance without specific training on the target motor task.

2017-10-01

This study examines how group members' questions shape member participation in health counselling and health education groups. The study applies conversation analytic principles as a method. The data consist of video-recorded health education lessons in secondary school and health counselling sessions for adults with a high risk of Type 2 diabetes. Group members' questions accomplish a temporary change in participatory roles. They are used to 1) request counselling, 2) do counselling or 3) challenge previous talk. They are usually treated as relevant and legitimate actions by the participants, but are occasionally interpreted as transitions outside the current action or topic. Group members' questions result in a shift from leader-driven to member-driven discussion. Thus they constitute a pivot point for detecting changes in participation in group interventions. Observing the occurrence of group members' questions helps group leaders to adjust their own actions accordingly and thus facilitate or guide group participation. Comparison of the type and frequency of members' questions is a way to detect different trajectories for delivering group interventions and can thus be used to develop methods for process evaluation of interventions.

All groups are differentiated into more or less group-prototypical members. Central members readily influence and lead the group, and they define its identity. Peripheral members can feel voiceless and marginalized, as well as uncertain about their membership status - they may engage in extreme behaviors to try to win acceptance. These relative prototypicality dynamics sometimes benefit group performance but sometimes compromise performance.

Prior cognitive activity implicitly modulates subsequent emotional responses to subliminally presented emotional stimuli.

2012-06-01

It has been reported that engagement in several kinds of cognitive activity can successfully inhibit unpleasant emotions. In this study, we tried to replicate the previous finding that cognitive activity can modulate subsequent psychological and physiological emotional processes and to investigate whether prior cognitive activity can attenuate implicit emotional processes triggered by subliminal emotional stimuli. Sixty students were randomly divided into three groups (cognitive task group, noncognitive task group, control group). The cognitive task group was asked to engage in an n-back task, while the control group was asked to stay calm. The noncognitive task group was asked to do a handgrip-squeezing task. All participants then engaged in a version of a subliminal affective priming task where they were unconsciously exposed to affectively negative pictures. The cognitive task group showed lower negative experiences after the subliminal affective priming task and a substantial reduction in their heart rate responses, as compared with the other groups. These results provide evidence that engagement in cognitive activity can attenuate emotional processes in an automatic and unconscious manner.

[Multiprofessional family-system training programme in psychiatry--effects on team cooperation and staff strain].

PubMed

Zwack, Julika; Schweitzer, Jochen

2008-01-01

How does the interdisciplinary cooperation of psychiatric staff members change after a multiprofessional family systems training programme? Semi-structured interviews were conducted with 49 staff members. Quantitative questionnaires were used to assess burnout (Maslach Burnout Inventory, MBI) and team climate (Team-Klima-Inventar, TKI). The multiprofessional training intensifies interdisciplinary cooperation. It results in an increased appreciation of the nurses involved and in a redistribution of therapeutic tasks between nurses, psychologists and physicians. Staff burnout decreased during the research period, while task orientation and participative security within teams increased. The multiprofessional family systems training appears suitable to improve quality of patient care and interdisciplinary cooperation and to reduce staff burnout.

Autocracy bias in informal groups under need for closure.

PubMed

Pierro, Antonio; Mannetti, Lucia; De Grada, Eraldo; Livi, Stefano; Kruglanski, Arie W

2003-03-01

Two experiments investigated the tendency of groups with members under high (vs. low) need for cognitive closure to develop an autocratic leadership structure in which some members dominate the discussion, constitute the "hubs" of communication, and influence the group more than other members. The first experiment found that high (vs. low) need for closure groups, as assessed via dispositional measure of the need for closure, manifested greater asymmetry of conversational floor control, such that members with autocratic interactional style were more conversationally dominant and influential than less autocratic members. The second experiment manipulated the need for closure via time pressure and utilized a social network analysis. Consistent with expectation, groups under time pressure (vs. no pressure) showed a greater asymmetry of participation, of centrality, and of prestige among the group members, such that the more focal members were perceived to exert the greater influence over the groups' decisions.

Beersma, Bianca; De Dreu, Carsten K W

2005-09-01

Two studies tested the effects of social motives during negotiation on postnegotiation group performance. In both experiments, a prosocial or a proself motivation was induced, and participants negotiated in 3-person groups about a joint market. In Experiment 1, groups subsequently performed an advertisement task. Consistent with the authors' predictions, results showed that proself groups performed worse on the convergent aspects of this task but better on the divergent aspects than prosocial groups. In Experiment 2, the authors manipulated social motive and negotiation (negotiation vs. no negotiation), and groups performed a creativity task (requiring divergent performance) or a planning task (requiring convergent performance). Proself groups showed greater dedication, functioned more effectively, and performed better than prosocial groups on the creativity task, whereas prosocial groups showed greater dedication, functioned more effectively, and performed better than proself groups on the planning task, and these effects only occurred when the task was preceded by group negotiation.

Hepatocellular carcinoma (HCC) is one of the major causes of morbidity, mortality and healthcare expenditure in patients with chronic liver disease. There are no consensus guidelines on diagnosis and management of HCC in India. The Indian National Association for Study of the Liver (INASL) set up a Task-Force on HCC in 2011, with a mandate to develop consensus guidelines for diagnosis and management of HCC, relevant to disease patterns and clinical practices in India. The Task-Force first identified various contentious issues on various aspects of HCC and these issues were allotted to individual members of the Task-Force who reviewed them in detail. The Task-Force used the Oxford Center for Evidence Based Medicine—Levels of Evidence of 2009 for developing an evidence-based approach. A 2-day round table discussion was held on 9th and 10th February, 2013 at Puri, Odisha, to discuss, debate, and finalize the consensus statements. The members of the Task-Force reviewed and discussed the existing literature at this meeting and formulated the INASL consensus statements for each of the issues. We present here the INASL consensus guidelines (The Puri Recommendations) on prevention, diagnosis and management of HCC in India. PMID:25755608

Judging Normality and Attractiveness in Faces: Direct Evidence of a More Refined Representation for Own-Race, Young Adult Faces.

2016-09-01

Young and older adults are more sensitive to deviations from normality in young than older adult faces, suggesting that the dimensions of face space are optimized for young adult faces. Here, we extend these findings to own-race faces and provide converging evidence using an attractiveness rating task. In Experiment 1, Caucasian and Chinese adults were shown own- and other-race face pairs; one member was undistorted and the other had compressed or expanded features. Participants indicated which member of each pair was more normal (a task that requires referencing a norm) and which was more expanded (a task that simply requires discrimination). Participants showed an own-race advantage in the normality task but not the discrimination task. In Experiment 2, participants rated the facial attractiveness of own- and other-race faces (Experiment 2a) or young and older adult faces (Experiment 2b). Between-rater variability in ratings of individual faces was higher for other-race and older adult faces; reduced consensus in attractiveness judgments reflects a less refined face space. Collectively, these results provide direct evidence that the dimensions of face space are optimized for own-race and young adult faces, which may underlie face race- and age-based deficits in recognition. © The Author(s) 2016.

Hepatocellular carcinoma (HCC) is one of the major causes of morbidity, mortality and healthcare expenditure in patients with chronic liver disease. There are no consensus guidelines on diagnosis and management of HCC in India. The Indian National Association for Study of the Liver (INASL) set up a Task-Force on HCC in 2011, with a mandate to develop consensus guidelines for diagnosis and management of HCC, relevant to disease patterns and clinical practices in India. The Task-Force first identified various contentious issues on various aspects of HCC and these issues were allotted to individual members of the Task-Force who reviewed them in detail. The Task-Force used the Oxford Center for Evidence Based Medicine-Levels of Evidence of 2009 for developing an evidence-based approach. A 2-day round table discussion was held on 9th and 10th February, 2013 at Puri, Odisha, to discuss, debate, and finalize the consensus statements. The members of the Task-Force reviewed and discussed the existing literature at this meeting and formulated the INASL consensus statements for each of the issues. We present here the INASL consensus guidelines (The Puri Recommendations) on prevention, diagnosis and management of HCC in India.

Emotion recognition is important for social interaction and communication, yet previous research has identified a cross-cultural emotion recognition deficit: Recognition is less accurate for emotions expressed by individuals from a cultural group different than one's own. The current study examined whether social categorization based on race, in the absence of cultural differences, influences emotion recognition in a diverse context. South Asian and White Canadians in the Greater Toronto Area completed an emotion recognition task that required them to identify the seven basic emotional expressions when posed by members of the same two groups, allowing us to tease apart the contributions of culture and social group membership. Contrary to our hypothesis, there was no mutual in-group advantage in emotion recognition: Participants were not more accurate at recognizing emotions posed by their respective racial in-groups. Both groups were more accurate at recognizing expressions when posed by South Asian faces, and White participants were more accurate overall compared to South Asian participants. These results suggest that in a diverse environment, categorization based on race alone does not lead to the creation of social out-groups in a way that negatively impacts emotion recognition.

Flexibility of associative learning can be revealed by establishing and then reversing cue-outcome discriminations. Here, we used functional MRI to examine whether neurobehavioral correlates of reversal-learning are impaired in White and Asian volunteers when initial learning involves fear-conditioning to a racial out-group. For one group, the picture of a Black male was initially paired with shock (threat) and a White male was unpaired (safe). For another group, the White male was a threat and the Black male was safe. These associations reversed midway through the task. Both groups initially discriminated threat from safety, as expressed through skin conductance responses (SCR) and activity in the insula, thalamus, midbrain and striatum. After reversal, the group initially conditioned to a Black male exhibited impaired reversal of SCRs to the new threat stimulus (White male), and impaired reversals in the striatum, anterior cingulate cortex, midbrain and thalamus. In contrast, the group initially conditioned to a White male showed successful reversal of SCRs and successful reversal in these brain regions toward the new threat. These findings provide new evidence that an aversive experience with a racial out-group member impairs the ability to flexibly and appropriately adjust fear expression towards a new threat in the environment.

Cooperative learning are being used increasingly in the university classroom, in order to promote teamwork among students, improve performance and develop interpersonal competences. Responsibility and cooperation are two fundamental pillars of cooperative learning. Team members' responsibility is a necessary condition for the team's success in the assigned tasks. Students must be aware that they depend on each other and should make their maximum effort. On the other hand, in efficient groups, the members cooperate and pool their efforts to achieve the proposed goals. In this research, we propose to create a Questionnaire of Group Responsibility and Cooperation in Learning Teams (CRCG) . Participants in this work were 375 students from the Faculty of Teacher Training of the University of Extremadura (Spain). The CRCG has very acceptable psychometric characteristics, good internal consistency, and temporal reliability. Moreover, structural equation analysis allowed us to verify that the latent variables in the two factors found are well defined and, therefore, their assessment is adequate. Besides, we found high significant correlations between the Learning Team Potency Questionnaire (CPEA) and the total score and the factors of the CRCG. This tool will evaluate cooperative skills and offer faculty information in order to prepare students for teamwork and conflict resolution.

ATLAS Experiment is an international collaboration where more than 37 countries, 172 institutes and laboratories, 2900 physicists, engineers, and computer scientists plus 700 students participate. The management of this teamwork involves several aspects such as institute contribution, employment records, members' appointment, authors' list, preparation and publication of papers and speakers nomination. Previously, most of the information was accessible by a limited group and developers had to face problems such as different terminology, diverse data modeling, heterogeneous databases and unlike users needs. Moreover, the systems were not designed to handle new requirements. The maintenance has to be an easy task due to the long lifetime experiment and professionals turnover. The Glance system, a generic mechanism for accessing any database, acts as an intermediate layer isolating the user from the particularities of each database. It retrieves, inserts and updates the database independently of its technology and modeling. Relying on Glance, a group of systems were built to support the ATLAS management and operation aspects: ATLAS Membership, ATLAS Appointments, ATLAS Speakers, ATLAS Analysis Follow-Up, ATLAS Conference Notes, ATLAS Thesis, ATLAS Traceability and DSS Alarms Viewer. This paper presents the overview of the Glance information framework and describes the privilege mechanism developed to grant different level of access for each member and system.
