BCube, an NSF EarthCube Building Block project, aims to improve efficiency and productivity of geoscientists who work across disciplinary boundaries by facilitating discovery and access of geoscience data, linking major data facilities, and creating a new paradigm for data advertising and discovery. In this presentation we describe the achievements to date of the BCube brokering and web crawling efforts, addressing focus areas and outcomes in both cyberinfrastructure and geocsciences. We describe science scenarios illustrating the research in the ocean, climate, hydrology and polar domains that is being supported by the BCube Broker. By providing mediation between a diversity of standards and protocols the broker makes it possible for the geoscientists working in these demains to discover and access high-value datasets via a cloud-based interface. An Accessor Development Kit (ADK) enables the community to develop modules that extend the capabilities of the broker. In addition, we describe the web crawling and semantic technologies that are being applied to find new geoscience-relevant datasets and services on the web.

POPPER, a simple programming language for probabilistic semantic inference in medicine.

PubMed

Robson, Barry

2015-01-01

Our previous reports described the use of the Hyperbolic Dirac Net (HDN) as a method for probabilistic inference from medical data, and a proposed probabilistic medical Semantic Web (SW) language Q-UEL to provide that data. Rather like a traditional Bayes Net, that HDN provided estimates of joint and conditional probabilities, and was static, with no need for evolution due to "reasoning". Use of the SW will require, however, (a) at least the semantic triple with more elaborate relations than conditional ones, as seen in use of most verbs and prepositions, and (b) rules for logical, grammatical, and definitional manipulation that can generate changes in the inference net. Here is described the simple POPPER language for medical inference. It can be automatically written by Q-UEL, or by hand. Based on studies with our medical students, it is believed that a tool like this may help in medical education and that a physician unfamiliar with SW science can understand it. It is here used to explore the considerable challenges of assigning probabilities, and not least what the meaning and utility of inference net evolution would be for a physician.

The Information and Communication Technology User Role: Implications for the Work Role and Inter-Role Spillover.

PubMed

Piszczek, Matthew M; Pichler, Shaun; Turel, Ofir; Greenhaus, Jeffrey

2016-01-01

Management and organization research has traditionally focused on employees' work role and the interface between their work and family roles. We suggest that persons assume a third role in modern society that is relevant to work and organizations, namely the Information and Communication Technology User (ICTU) role. Based on role theory and boundary theory, we develop propositions about the characteristics of this role, as well as how ICTU role characteristics are related to boundary spanning activity, inter-role spillover with the work role, and work role performance. To this end, we first conceptualize the ICTU role and its associations with work and family roles. We then apply identity theory and boundary management theory to advance our understanding of how the ICTU role is related to criteria that are important to individuals and to organizations, namely self-selection into certain types of work roles and positive and negative inter-role spillover. The implications of this role for theory, research, and practice in management and organizations are discussed.

Biogas represents an important source of renewable energy issued from biological degradation of biomass. It is planned to produce in Europe the amount of biogas equivalent to 6400 kWh electricity and 4500 kteo (kilo tons equivalent oil) in 2020. Currently the biogas is used in cogeneration engines to produce heat and electricity directly in farms or it is injected in gas networks after purification and odorisation. The aim of this work is to propose a third option that consists of valorization of biogas by transformation into liquid hydrocarbons like acetone, methanol, ethanol, acetic acid etc. These chemicals, among the most important feed materials for chemical industries, retain CO2 molecules participating to reduce the greenhouse gas emissions and have high storage energy capacity. We developed a low temperature atmospheric plasma-catalyst reactor (surface dielectric barrier discharge) to transform biogas into chemicals. The conversion rates of CH4 and CO2 are respectively about 50% and 30% depending on operational conditions. The energetic cost is 25 eV/molecule. The yields of liquid hydrocarbon reaches currently 10% wt. More the 11 liquid chemicals are observed in the liquid fraction. Acknowledgements are due to SPC Programme Energie de demain.

Betwixt and between: Role conflict, role ambiguity and role definition in project-based dual-leadership structures.

PubMed

Ebbers, Joris J; Wijnberg, Nachoem M

2017-11-01

Project-based organizations in the film industry usually have a dual-leadership structure, based on a division of tasks between the dual leaders - the director and the producer - in which the former is predominantly responsible for the artistic and the latter for the commercial aspects of the film. These organizations also have a role hierarchically below and between the dual leaders: the 1st assistant director. This organizational constellation is likely to lead to role conflict and role ambiguity experienced by the person occupying that particular role. Although prior studies found negative effects of role conflict and role ambiguity, this study shows they can also have beneficial effects because they create space for defining the role expansively that, in turn, can be facilitated by the dual leaders defining their own roles more narrowly. In a more general sense, this study also shows the usefulness of analyzing the antecedents and consequences of roles, role definition, and role crafting in connection to the behavior of occupants of adjacent roles.

I am my (high-power) role: power and role identification.

PubMed

Joshi, Priyanka D; Fast, Nathanael J

2013-07-01

Research indicates that power liberates the self, but findings also show that the powerful are susceptible to situational influences. The present article examines whether enacting roles that afford power leads people to identify with the roles or, instead, liberates them from role expectations altogether. The results of three experiments support the hypothesis that power enhances role identification. Experiment 1 showed that enacting a particular role resulted in greater implicit and explicit role identification when the role contained power. In Experiment 2, infusing a role with power resulted in greater role identification and role-congruent behavior. Experiment 3 demonstrated that power resulted in greater role-congruent self-construal, such that having power in a close relationship caused participants to define themselves relationally, whereas having power in a group situation caused participants to embrace a collective self-construal. Implications for research on power, roles, and the self are discussed.

Gender, multiple roles, role meaning, and mental health.

PubMed

Simon, R W

1995-06-01

This paper examines gender differences in the consequences of combining spouse, parent, and worker roles for mental health. I suggest that work and family roles have different meanings for males and females, and that differences in the meaning of these roles may be partially responsible for why the mental health advantages of holding multiple roles are fewer for women than for men. Based on qualitative analyses of follow-up, in-depth interviews with 40 employed married parents who participated in a community panel study of mental health, I find that sex differences in the perceived relationship between work and family roles may help account for sex differences in distress by contributing to male-female differences in both the extent and nature of work-parent conflicts, attributions of responsibility for marital problems, feelings of guilt, and self-evaluations as parents and spouses. By identifying gender differences in the meaning of roles among individuals who have the same multiple role configuration, and suggesting how these differences can help explain sex differences in well-being; this research may expand existing theories about the mental health consequences of multiple role involvements.

Role Overload, Role Self Distance, Role Stagnation as Determinants of Job Satisfaction and Turnover Intention in Banking Sector

Purpose: This study examined the relationship of the organizational role stress: Role overload, role self-distance, and role stagnation with job satisfaction and turnover intention with a sample of banking employees in India. Methodology: In this research, we used the RODS scale developed by Prohit and Pareek (2010) for measuring occupational role scale. The reliability of the scale came out to be 0.71. Findings: The majority of employees of all ranks, in both private and public sector banks, suffer from high role stress of all types. It was found that role overload and role stagnation are inversely associated with banking employees' job satisfaction. Private sector bank employees have more role stress and more unsatisfied than employees of public sector banks. Employees Turnover intention was found to be positively impacted by job satisfaction, contrary to many other studies. Possible reasons have been suggested. Job satisfaction was found to play a partial mediating role in the relationship between role overload and turnover intention with 40% mediation. Further, employees with longer tenure (work experience) have less role stress and are more satisfied. Originality: This study is unique in the sense there is hardly any study linking role stress to job satisfaction and turnover intention, specially in Indian context. PMID:29200554

RESUME Plus de trois millions de morts sont attribués au tabagisme dans le monde par an, et l’usage de tabac est en progression dans les pays en voie de développement. L’usage de tabac est donc une des rares causes de mortalité qui augmente, avec une prévision de plus de 10 millions de morts par an dans 30–40 ans. Le cannabis ou marijuana est la drogue illicite la plus consommée dans le monde et il n’y a actuellement pas de traitement disponible. Bien que les systèmes dopaminergiques jouent un rôle central dans les effets renforçants des drogues, d’autres systèmes sont impliqués. Nous présentons ici des résultats récents obtenus avec des antagonistes des récepteurs cannabinoides CB1, des récepteurs D3 de la dopamine et des récepteurs opioïdes. Ces antagonistes qui modulent de façon directe ou indirecte la transmission dopaminergique cérébrale représentent des approches prometteuses pour le traitement du tabagisme ou de la dépendance au cannabis. Ces approches sont à valider dans des essais cliniques. PMID:18663981

Roles of Communication Problems and Communication Strategies on Resident-Related Role Demand and Role Satisfaction.

PubMed

Savundranayagam, Marie Y; Lee, Christopher

2017-03-01

This study investigated the impact of dementia-related communication difficulties and communication strategies used by staff on resident-related indicators of role demand and role satisfaction. Formal/paid long-term care staff caregivers (N = 109) of residents with dementia completed questionnaires on dementia-related communication difficulties, communication strategies, role demand (ie, residents make unreasonable demands), and role satisfaction (measured by relationship closeness and influence over residents). Three types of communication strategies were included: (a) effective repair strategies, (b) completing actions by oneself, and (c) tuning out or ignoring the resident. Analyses using structural equation modeling revealed that communication problems were positively linked with role demand. Repair strategies were positively linked with relationship closeness and influence over residents. Completing actions by oneself was positively linked to role demand and influence over residents, whereas tuning out was negatively linked with influence over residents. The findings underscore that effective caregiver communication skills are essential in enhancing staff-resident relationships.

The expanding role(s) of eosinophils in health and disease

PubMed Central

Jacobsen, Elizabeth A.; Helmers, Richard A.

2012-01-01

Surprisingly, the role(s) of eosinophils in health and disease is often summarized by clinicians and basic research scientists as a pervasive consensus opinion first learned in medical/graduate school. Eosinophils are rare white blood cells whose activities are primarily destructive and are only relevant in parasitic infections and asthma. However, is this consensus correct? This review argues that the wealth of available studies investigating the role(s) of eosinophils in both health and disease demonstrates that the activities of these granulocytes are far more expansive and complex than previously appreciated. In turn, this greater understanding has led to the realization that eosinophils have significant contributory roles in a wide range of diseases. Furthermore, published studies even implicate eosinophil-mediated activities in otherwise healthy persons. We suggest that the collective reports in the literature showing a role for eosinophils in an ever-increasing number of novel settings highlight the true complexity and importance of this granulocyte. Indeed, discussions of eosinophils are no longer simple and more often than not now begin with the question/statement “Did you know …?” PMID:22936660

Role of Atmospheric Transport on the Arctic Amplification: Adjusting Role

NASA Astrophysics Data System (ADS)

KUG, J.; Yim, B.; Jin, F.

2013-12-01

It is controversial whether the atmospheric transport plays a role in arctic amplification. Recently, Hwang et al. (2011) showed that the magnitude of the arctic amplification is negatively correlated with anomalous poleward atmospheric transport. That is, when the arctic amplification is strong (weak), the atmospheric transport plays a negative (positive) role in the arctic amplification. In this study, it is discussed what is a physical mechanism to determine the role of atmospheric transport and relation with the arctic amplification. Here, we suggest adjusting roles of atmospheric transport. The strength of local feedback over the Arctic determines zonal wind changes. The zonal wind changes are determined by two factors. The first one is polar cap cooling, and second is surface warming. They play opposite roles. So, there will be two different zonal wind responses in high-latitude to the greenhouse warming. Depending on the zonal wind response, the atmospheric transport can play a different role because the zonal wind changes can organize synoptic eddy feedbacks including heat flux, which largely contributes to poleward energy transport. We show here that when polar cap cooling is strong, and surface warming over Arctic is relatively weak, the Jet stream tends to be shifted poleward, so it leads to poleward atmospheric transport. On the other hand, when the surface warming is too strong, it lead to southward shift of Jet stream and equatorward atmospheric transport, which paly a negative role in the Arctic amplification.

The importance of role sending in the sensemaking of change agent roles.

PubMed

Tucker, Danielle A; Hendy, Jane; Barlow, James

2015-01-01

The purpose of this paper is to investigate what happens when a lack of role-sending results in ambiguous change agent roles during a large scale organisational reconfiguration. The authors consider the role of sensemaking in resolving role ambiguity of middle manager change agents and the consequences of this for organisational restructuring. Data were collected from a case study analysis of significant organisational reconfiguration across a local National Health Service Trust in the UK. Data consists of 82 interviews, complemented by analysis of over 100 documents and field notes from 51 hours of observations collected over five phases covering a three year period before, during and after the reconfiguration. An inductive qualitative analysis revealed the sensemaking processes by which ambiguity in role definition was resolved. The data explains how change agents collectively make sense of a role in their own way, drawing on their own experiences and views as well as cues from other organisational members. The authors also identified the organisational outcomes which resulted from this freedom in sensemaking. This study demonstrates that by leaving too much flexibility in the definition of the role, agents developed their own sensemaking which was subsequently very difficult to manipulate. In creating new roles, management first needs to have a realistic vision of the task and roles that their agents will perform, and second, to communicate these expectations to both those responsible for recruiting these roles and to the agents themselves. Much of the focus in sensemaking research has been on the importance of change agents' sensemaking of the change but there has been little focus on how change agents sensemake their own role in the change.

2007-01-01

Background Little research has been conducted to investigate role stress experienced by faculty members in medical schools in developing countries. This becomes even more important when the process of reform in medical education has already taken place, such as the case of Iran. The objectives of this study were to investigate and assess the level and source of role-related stress as well as dimensions of conflict among the faculty members of Iranian medical schools. Variables like the length of academic work, academic rank, employment position, and the departments of affiliation were also taken into consideration in order to determine potentially related factors. Methods A survey was conducted at three different ranks of public medical schools. The validated Organizational Role Stress Scale was used to investigate the level of role stress and dimensions of role conflict among medical faculty members. The response rate was 66.5%. Results The findings show that role stress was experienced in high level among almost all faculty members. All three studied medical schools with different ranks are threatened with relatively the same levels of role stress. Specific differences were found among faculty members from different disciplines, and academic ranks. Also having permanent position and the length of services had significant correlation with the level of role stress. The major role- related stress and forms of conflict among faculty members were role overload, role expectation conflict, inter-role distance, resource inadequacy, role stagnation, and role isolation. Conclusion The most role-related stressors and forms of conflict among faculty members include too many tasks and everyday work load; conflicting demands from colleagues and superiors; incompatible demands from their different personal and organizational roles; inadequate resources for appropriate performance; insufficient competency to meet the demands of their role; inadequate autonomy to make decision on

Social roles among recruits in Switzerland: Do social roles relate to alcohol use and does role change have an impact?

Young men are likely to report high levels of alcohol use. Previous studies found a reduction in alcohol use when adopting adult social roles. This study examines the frequency of parenthood, partnership and stable employment among young men in Switzerland. It tests whether the alcohol use of those with adult social roles differs from those without and whether changes in social roles relate to changes in alcohol use. Data was available from 5025 men (20.0 years) at baseline (August 2010 to November 2011) and 15 months later. Changes in social roles and their impact on alcohol use were examined in multiple regression models. At baseline, 15.8% had a job and 4.9% a stable partner, and 1.5% had a child or were expecting one (30.5%, 6.1% and 2.2% at follow-up). Having a partner was associated with a significant decrease in annual frequency of drinking and weekly risky single-occasion drinking (RSOD) at follow-up. A higher number of social roles at follow-up was associated with a significant decrease in weekly RSOD. Apart from a significant decrease in weekly RSOD among those remaining in a stable partnership, role development was not found to have significant effects on alcohol use between baseline and follow-up. In Switzerland, an early engagement in permanent social roles is uncommon. Nevertheless, holding single or multiple social roles was commonly associated with reduced alcohol use, although not always significantly so. In western European countries, the engagement in adult social roles is postponed to later ages. Copyright © 2015. Published by Elsevier Ltd.

Mexican American Adolescents’ Gender Role Attitude Development: The Role of Adolescents’ Gender and Nativity and Parents’ Gender Role Attitudes

Gender development has long term implications for education and career endeavors and family formation behaviors, but we know very little about the role of sociocultural factors in developmental and individual differences. In this study, we investigated one domain of gender development, gender role attitudes, in Mexican American adolescents (N = 246; 51% female), using four phases of longitudinal data across eight years. Data were collected when adolescents averaged 12.51 years (SD = 0.58), 14.64 years (SD = 0.59), 17.72 years (SD = 0.57), and 19.60 years of age (SD = 0.66). Mothers’ and fathers’ gender role attitudes also were assessed in Phases 1, 3, and 4. Findings revealed that gender attitude development varied as a function of the interaction between adolescents’ nativity and gender. Among Mexico-born adolescents, females exhibited significant declines in traditional attitudes from early to late adolescence, but males’ attitudes were stable over time. U.S.-born females and males, in contrast, did not differ in their gender attitude trajectories. Examining the links between mothers’, fathers’, and adolescents’ gender role attitudes revealed within-person associations between mothers’ and adolescents’ gender role attitudes: on occasions when mothers reported more traditional attitudes relative to their own cross-time average, adolescents also reported more traditional attitudes than usual. In addition, fathers’ more traditional gender role attitudes were associated with daughters’, but not sons’, more traditional gender role attitudes at the between-person level. The discussion focuses on the interpretation of Mexican American adolescents’ gender role attitude development from a cultural ecological perspective. PMID:24777649

Development and validation of the work-family-school role conflicts and role-related social support scales among registered nurses with multiple roles.

Xu, Lijuan; Song, Rhayun

2013-10-01

The purpose of this study was to develop work-family-school role conflicts and role-related social support scales, and to validate the psychometrics of those scales among registered nurses with multiple roles. The concepts, generation of items, and the scale domains of work-family-school role conflicts and role-related social support scales were constructed based on a review of the literature. The validity and reliability of the scales were examined by administering them to 201 registered nurses who were recruited from 8 university hospitals in South Korea. The content validity was examined by nursing experts using a content validity index. Exploratory factor analysis and confirmatory factor analysis were used to establish the construct validity. The correlation with depression was examined to assess concurrent validity. Finally, internal consistency was assessed using Cronbach's alpha coefficients. The work-family-school role conflicts scale comprised ten items with three factors: work-school-to-family conflict (three items), family-school-to-work conflict (three items), and work-family-to-school conflict (four items). The role-related social support scale comprised nine items with three factors: support from family (three items), support from work (three items), and support from school (three items). Cronbach's alphas were 0.83 and 0.76 for the work-family-school role conflicts and role-related social support scales, respectively. Both instruments exhibited acceptable construct and concurrent validity. The validity and reliability of the developed scales indicate their potential usefulness for the assessment of work-family-school role conflict and role-related social support among registered nurses with multiple roles in Korea.

Many athletes experience a discrepancy between the roles they expect to fulfill and the roles they eventually occupy. Drawing from met expectations theory, we applied response surface methodology to examine how role expectations, in relation to role experiences, influence perceptions of group cohesion among Canadian Interuniversity Sport athletes (N = 153). On the basis of data from two time points, as athletes approached and exceeded their role contribution expectations, they reported higher perceptions of task cohesion. Furthermore, as athletes approached and exceeded their social involvement expectations, they reported higher perceptions of social cohesion. These response surface patterns-pertaining to task and social cohesion-were driven by the positive influence of role experiences. On the basis of the interplay between athletes' role experiences and their perception of the group environment, efforts to improve team dynamics may benefit from focusing on improving the quality of role experiences, in conjunction with developing realistic role expectations.

Gender development has long term implications for education and career endeavors and family formation behaviors, but we know very little about the role of sociocultural factors in developmental and individual differences. In this study, we investigated one domain of gender development, gender role attitudes, in Mexican-American adolescents (N = 246; 51 % female), using four phases of longitudinal data across 8 years. Data were collected when adolescents averaged 12.51 years (SD = 0.58), 14.64 years (SD = 0.59), 17.72 years (SD = 0.57), and 19.60 years of age (SD = 0.66). Mothers' and fathers' gender role attitudes also were assessed in Phases 1, 3, and 4. Findings revealed that gender attitude development varied as a function of the interaction between adolescents' nativity and gender. Among Mexico-born adolescents, females exhibited significant declines in traditional attitudes from early to late adolescence, but males' attitudes were stable over time. U.S.-born females and males, in contrast, did not differ in their gender attitude trajectories. Examining the links between mothers', fathers', and adolescents' gender role attitudes revealed within-person associations between mothers' and adolescents' gender role attitudes: on occasions when mothers reported more traditional attitudes relative to their own cross-time average, adolescents also reported more traditional attitudes than usual. In addition, fathers' more traditional gender role attitudes were associated with daughters', but not sons', more traditional gender role attitudes at the between-person level. The discussion focuses on the interpretation of Mexican-American adolescents' gender role attitude development from a cultural ecological perspective.

Background As medical students spend most of their time with their clinical teachers and imitate their roles and characteristics during the school year, it is important to identify the roles and characteristics that they find essential in their role models. These traits play a part in their future professions as doctors. Objective The aim of this study was to determine the perspective of students, interns, and residents regarding the roles and characteristics of a clinical role model. Methods In an analytical cross-sectional study, a structured and self-developed questionnaire was completed by 185 medical students at educational hospitals of Kerman University of Medical Sciences during April and May 2015. Participants were selected using convenience sampling method. For data analysis, we used descriptive and inferential statistics. SPSS software version 16 was used as needed. Results In total, 90 medical students (48.7%), 65 interns (35.1%), and 30 residents (16.2%) participated in this study. Male respondents (n=75) comprised 40.5% and female respondents (n=110) 59.5% of the study sample. The three most important roles of a clinical teacher were organizer role (99.7), teacher role (101.7), and supporter role (109.5) for students, interns, and residents respectively. On the other hand, supporter role (85.4), communicator role (86.4) and organizer role (83.4) were ranked as the least important for students, interns, and residents respectively. There was no significant association among the three batches and the roles of a clinical teacher (p>0.05). Conversely, Females rated the roles of a clinical teacher significantly higher than males (p<0.05). Conclusions As teachers are frequently perceived by students as role models in medical schools, great attention should be given to their roles. Teachers must be aware that their roles have an impact on students’ professional development and performance. PMID:28607645

Scientific evidence has shown Coriolus versicolor (L. ex Fr.) Quel (also known as Yunzhi) has the role of immunomodulator in therapeutic effect. The aim of this in vitro study was to investigate the antioxidative effect of Yunzhi and to explore the mechanisms behind its DNA protection. Commercial Yunzhi extract was dissolved in water and diluted in five concentrations (10(1)-10(5) μg/L) with appropriate buffers. Lymphocytes harvested from three healthy subjects were incubated with Yunzhi extract for 30 min. Cells were then subjected to 5 min oxidant challenge by 45 μM hydrogen peroxide. The standard alkaline comet (SAC) assay and lysed cell comet (LCC) assay were performed in parallel. DNA damage of each treatment was scored under a fluorescence microscope and compared with the cells without Yunzhi pretreatment. U-shaped dose-response was seen in both versions of the comet assay. Yunzhi at 10(4) μg/L demonstrated a genoprotective effect against oxidative damage in the SAC assay (25% decrease in comet score). In the LCC assay, a trend of protection in lymphocytes was observed but it did not reach statistical significance. A direct antioxidant effect of Yunzhi against oxidant challenge on the DNA of lymphocytes was evidenced. The active component in Yunzhi was likely to be membrane permeable.

Provider Role Attitudes, Marital Satisfaction, Role Overload, and Housework: A Dyadic Approach

2010-01-01

Treating the marital dyad as the unit of analysis, this study examined the within-couple patterning of 272 dual-earner spouses’ provider role attitudes and their longitudinal associations with marital satisfaction, role overload, and the division of housework. Based on the congruence of husbands’ and wives’ provider role attitudes, couples were classified into one of four types: (1) main-secondary, (2) coprovider, (3) ambivalent coprovider, and (4) mismatched couples. Nearly half of all spouses differed in their attitudes about breadwinning. A series of mixed model ANCOVAs revealed significant between- and within-couple differences in human capital characteristics, spouses’ perceptions of marital satisfaction and role overload, and the division of housework across 3 years of measurement. Coprovider couples reported higher levels of marital satisfaction and a more equitable division of housework than the other couple groups. Wives in the ambivalent coprovider couples’ group reported higher levels of role overload than their husbands to a greater extent than was found in the other couple groups. As the first study to adopt a dyadic approach that considers the meanings that both spouses in dual-earner couples ascribe to paid employment, these findings advance understanding of how dual-earner spouses’ provider role attitudes serve as contexts for marital quality, behavior, and role-related stress.

Fernández, Juan; Quiroga, M Angeles; del Olmo, Isabel; Aróztegui, Javier; Martín, Arantxa

2011-11-01

This study was designed to develop a computerized test to assess gender roles. This test is presented as a decision-making task to mask its purpose. Each item displays a picture representing an activity and a brief sentence that describes it. Participants have to choose the most suitable sex to perform each activity: man or woman. The test (Gender Roles Test, GRT-36) consists of 36 items/activities. The program registers both the choices made and their response times (RTs). Responses are considered as stereotyped when the chosen sex fits stereotyped roles and non-stereotyped when the chosen sex does not fit stereotyped roles. Individual means (RTs) were computed for stereotyped and non-stereotyped responses, differentiating between domestic and work spheres. A "D" score, reflecting the strength of association between activities and sex, was calculated for each sphere and sex. The study incorporated 78 participants (69% women and 31% men) ranging from 19 to 59 years old. The results show that: (a) reading speed does not explain the variability in the RTs; (b) RTs show good internal consistency; (c) RTs are shorter for stereotyped than for neutral stimuli; (d) RTs are shorter for stereotyped than for non-stereotyped responses. Intended goals are supported by obtained results. Scores provided by the task facilitate both group and individual detailed analysis of gender role, differentiating the gender role assigned to men from that assigned to women, at the domestic and work spheres. Obtained data fall within the scope of the genderology and their implications are discussed.

The objective of this pilot study was to determine women's perceptions of their levels of maternal role competence at discharge from a Baby-Friendly hospital. A convenience sample of 30 women completed two self-report questionnaires: a demographic questionnaire and the Perceived Maternal Parenting Self-Efficacy scale. Women report that they perceived high levels of maternal role competence with a mean total score of 69.80 (standard deviation = 6.86) out of 80. As women experience breastfeeding in Baby-Friendly hospitals, maternal role competence may develop with appropriate support. © 2017 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

Psychological effects of dog ownership: role strain, role enhancement, and depression.

Cline, Krista Marie Clark

2010-01-01

The purpose of this study is to examine the link between multiple roles and depression and to attempt to provide a clearer answer to the question of what effect, if any, the role of dog ownership plays. Role strain and role enhancement theories are drawn upon to study this relationship. Ordinary least squares regression is used to examine a national sample of 201 adults in the United States. Findings revealed sex and marital status differences in the relationship between dog ownership and well-being, with women and single adults more likely to benefit from dog ownership. The findings presented here suggest that inattention to variations in marital status and sex may have been one factor in the inconsistency in the literature on pets and well-being.

Mentoring relationships and the levels of role conflict and role ambiguity experienced by novice nursing faculty.

PubMed

Specht, Jennifer A

2013-01-01

This study explored the effect of mentoring on the levels of role conflict and role ambiguity experienced by novice nursing faculty related to their transitions into academe using a descriptive, comparative design. It also measured the relationship between the quality of mentoring experiences of novice nursing faculty and their levels of role conflict and role ambiguity using a correlational design. P. Benner's (1984) novice to expert model was utilized as a framework for successful role transition. J. R. Rizzo, R. J. House, and S. I. Lirtzman's (1970) role conflict and role ambiguity scale was used to measure the levels of role conflict and role ambiguity experienced by novice nursing faculty. Results indicate that participants (n = 224) who were mentored have significantly lower levels of role conflict (M = 3.57) and role ambiguity (M = 3.02) than those who were not mentored (M = 4.62 and M = 3.90, respectively). Also significant, the higher the participants' reported levels of quality of mentoring experiences were, the lower their levels of role conflict and role ambiguity were. The results of this study indicate that mentoring eases the transition of novice nursing faculty from practice into academe by decreasing the degree of role ambiguity and role conflict that they experience. © 2013.

Sociophonetics: The Role of Words, the Role of Context, and the Role of Words in Context.

Hay, Jennifer

2018-03-02

This paper synthesizes a wide range of literature from sociolinguistics and cognitive psychology, to argue for a central role for the "word" as a vehicle of language variation and change. Three crucially interlinked strands of research are reviewed-the role of context in associative learning, the word-level storage of phonetic and contextual detail, and the phonetic consequences of skewed distributions of words across different contexts. I argue that the human capacity for associative learning, combined with attention to fine-phonetic detail at the level of the word, plays a significant role in predicting a range of subtle but systematically robust observed socioindexical patterns in speech production and perception.

Role transition in primary care settings.

PubMed

Holt, Ian G S

2008-01-01

This paper reports on research that explored how nurses who are engaged in advanced practice adapt and adjust to their roles in primary and community health settings. Successive government policy has highlighted how the changing roles of nurses, who are engaged in advanced practice, are crucial to delivering high-quality patient care. The paper offers a framework for role transition which is potentially generalisable to doctors, physiotherapists and other healthcare professionals. The aim of the study was to enable an understanding of role transition, from a study of nurses going through changes to their roles or moving to new roles. The intended purpose of the study was to explore what was going on within role transition, and considers by what process(es) role transition evolves or is experienced. Eleven nurses' actions, expectations, and experiences of role transition were explored, within three district nurse centres and two community NHS trusts. Data were collected from participant and non-participant observation, content analysis of job descriptions and from individual and group interviews, including semi-structured schedules and focus group techniques. Data were comparatively analysed to conceptualise and saturate core themes, which were discussed and developed with participants and healthcare managers. A theory of role transition is proposed through a model representing the 'who', 'what', 'where' and 'how' of role transition, through four concepts of centring identity(ies); focusing role(s); enacting role(s); and shaping role(s). Identity was regarded by the participants as being the role, the person, and as part of a group. Current and anticipated role foci directed enactment of role within given contexts and resources, while shaping of role involved a balance of role loss and role expansion. This article presents a theory of role transition for primary care professionals.

Women combining paid employment with dual caring responsibilities for children and aging parents, otherwise known as the sandwich generation, experience both benefits and costs related to role participation and quality of life. However, previous literature is inconclusive regarding the impact of this role combination on role balance. In the context of these mixed findings on role balance for working sandwich generation women, this study aimed to explore how within role characteristics and between role interactions are related to role balance for these women. This aim was achieved through the use of a questionnaire administered to 18 Australian working sandwich generation women. Data were analyzed using descriptive statistics and correlation coefficients, with findings suggesting the women studied tended to experience neither role balance or role imbalance. Within-role characteristics, particularly within the mother and family member roles, were related to role balance. In addition, between-role conflict and role interactions involving either the home maintainer or family member roles had the greatest impact on role balance.

Categorizing entities by common role.

PubMed

Goldwater, Micah B; Markman, Arthur B

2011-04-01

Many categories group together entities that play a common role across situations. For example, guest and host refer to complementary roles in visiting situations and, thus, are role-governed categories (A. B. Markman & Stilwell, Journal of Experiment & Theoretical Artificial Intelligence, 13, 329-358, 2001). However, categorizing an entity by role is one of many possible classification strategies. This article examines factors that promote role-governed categorization over thematic-relation-based categorization (Lin & Murphy, Journal of Experimental Psychology: General, 130, 3-28, 2001). In Experiments 1a and 1b, we demonstrate that the use of novel category labels facilitates role-governed categorization. In Experiments 2a and 2b, we demonstrate that analogical comparison facilitates role-governed categorization. In Experiments 1b and 2b, we show that these facilitatory factors induce a general sensitivity to role information, as opposed to only promoting role-governed categorization on an item-by-item basis.

2011-01-01

This exploratory study was designed to examine the relationship between gender role dimensions derived from the Bem Sex-Role Inventory (BSRI) and the 4 dimensions of gender role conflict represented on the Gender Role Conflict Scale (GRCS) using a sample (N = 400) composed of exclusively gay men. Results from regression of 3 BSRI scores (femininity, social masculinity, personal masculinity) on the 4 subscale scores of the GRCS indicated that gender role conflict was most strongly and positively associated with the negative aspect of masculinity (social masculinity), accounting for about 11% of variability in social masculinity scores. In particular, the success-power-competition dimension of the GRCS was the major predictor of social masculinity in gay men. Gender role conflict was also strongly but negatively associated with femininity, accounting for approximately 10% of the variance in femininity scores among the men in the sample. Implications and recommendations for further studies are discussed.

A case for multi-model and multi-approach based event attribution: The 2015 European drought

Science on the role of anthropogenic influence on extreme weather events such as heat waves or droughts has evolved rapidly over the past years. The approach of "event attribution" compares the occurrence probability of an event in the present, factual world with the probability of the same event in a hypothetical, counterfactual world without human-induced climate change. Every such analysis necessarily faces multiple methodological choices including, but not limited to: the event definition, climate model configuration, and the design of the counterfactual world. Here, we explore the role of such choices for an attribution analysis of the 2015 European summer drought (Hauser et al., in preparation). While some GCMs suggest that anthropogenic forcing made the 2015 drought more likely, others suggest no impact, or even a decrease in the event probability. These results additionally differ for single GCMs, depending on the reference used for the counterfactual world. Observational results do not suggest a historical tendency towards more drying, but the record may be too short to provide robust assessments because of the large interannual variability of drought occurrence. These results highlight the need for a multi-model and multi-approach framework in event attribution research. This is especially important for events with low signal to noise ratio and high model dependency such as regional droughts. Hauser, M., L. Gudmundsson, R. Orth, A. Jézéquel, K. Haustein, S.I.

2007-01-01

Nurses' perceptions of their role are influenced by societal attitudes, government policies and trends in professional issues. Dynamic factors in contemporary health environments challenge traditional nursing roles, in particular those of community nurses. Role theory is a conceptual framework that defines how individuals behave in social situations and how these behaviours are perceived by external observers. This paper reviews the role theory literature as a conceptual framework to explore community nurses' perceptions of their role. Three theoretical perspectives of role theory have emerged from the literature review: 1. social structuralism 2. symbolic interactionism and 3. the dramaturgical perspective. These philosophical perspectives provide a useful framework to investigate the role of community nurses in the contemporary health care system.

Evidence for the social role theory of stereotype content: observations of groups' roles shape stereotypes.

PubMed

Koenig, Anne M; Eagly, Alice H

2014-09-01

In applying social role theory to account for the content of a wide range of stereotypes, this research tests the proposition that observations of groups' roles determine stereotype content (Eagly & Wood, 2012). In a novel test of how stereotypes can develop from observations, preliminary research collected participants' beliefs about the occupational roles (e.g., lawyer, teacher, fast food worker, chief executive officer, store clerk, manager) in which members of social groups (e.g., Black women, Hispanics, White men, the rich, senior citizens, high school dropouts) are overrepresented relative to their numbers in the general population. These beliefs about groups' typical occupational roles proved to be generally accurate when evaluated in relation to data from the Bureau of Labor Statistics. Then, correlational studies predicted participants' stereotypes of social groups from the attributes ascribed to group members' typical occupational roles (Studies 1a, 1b, and 1c), the behaviors associated with those roles (Study 2), and the occupational interest profile of the roles (Study 3). As predicted by social role theory, beliefs about the attributes of groups' typical roles were strongly related to group stereotypes on both communion and agency/competence. In addition, an experimental study (Study 4) demonstrated that when social groups were described with changes to their typical social roles in the future, their projected stereotypes were more influenced by these future roles than by their current group stereotypes, thus supporting social role theory's predictions about stereotype change. Discussion considers the implications of these findings for stereotype change and the relation of social role theory to other theories of stereotype content. 2014 APA, all rights reserved

Deployed communication between the Role 3 and Role 1.

Parsons, Iain T

2015-06-01

The discharge summary is the most common method for documenting a patient's diagnostic findings, hospital management and arrangements for post-discharge follow up. After being discharged from hospital, patients are routinely reviewed without a discharge summary being available. A recent review revealed that a significant proportion of patients discharged from the Role 3 had no evidence of their admission on their permanent medical record. The aim of this audit was to assess the transition of discharge summaries from Role 3 to Role 1 during Op HERRICK 18. The intention was to review where errors in the transfer of discharge information between Role 3 and Role 1 might be occurring with a view to implementing improvements. Two audits assessed the delivery of discharge information. A re-audit was performed 1 month after a system was implemented. The transfer of discharge information was poor with only 1/40 (2.5%) summaries arriving from R3 to R1. Following implementation of a system the transfer of discharge information improved to 24/30 (80%). The adoption of a system to transit discharge information from R3 to R1 resulted in a drastic improvement. Ideally, a future electronic patient record system used by all facets of Defence Medical Services would limit the potential for future adverse events due to communication failure. Regular audits assessing the transfer of discharge information should form part of standard audit cycles in future contingency operations. Published by the BMJ Publishing Group Limited.

Increasingly, women simultaneously balance the roles of mother, parental carer and worker. However, individual role balance strategies among these working 'sandwich' generation women have not been thoroughly explored. Eighteen women combining these three roles were interviewed about their individual role balance strategies. Findings were identified through the framework analysis technique, underpinned by the Model of Juggling Occupations. Achieving and maintaining role balance was explained as a complex process accomplished through a range of strategies. Findings revealed the women used six within-role balance strategies: living with integrity, being the best you can, doing what you love, loving what you do, remembering why and searching for signs of success. The women also described six between-role balance strategies: maintaining health and wellbeing, repressing perfectionism, managing time and energy, releasing responsibility, nurturing social connection and reciprocating. These findings provide a basis for health care providers to understand and potentially support working 'sandwich' generation women.

This article suggests that a more effective way to build and manage your medical practice team is to define team roles through employee behaviors. It provides 10 rules of behavioral team roles that can help practice managers to select and build high-performing teams, build more productive team relationships, improve the employee recruitment process, build greater team trust and understanding; and increase their own effectiveness. This article describes in detail Belbin's highly regarded and widely used team role theory and summarizes four additional behavioral team role theories and systems. It offers lessons learned when applying team role theory to practice. Finally, this article offers an easy-to-implement method for assessing current team roles. It provides a simple four-question checklist that will help practice managers balance an imbalanced medical practice team.

Role Model, Hero or Champion? Children's Views Concerning Role Models

Background: Claims that male role models can improve the behaviour and achievement of boys are familiar and persistent. However, research has not confirmed such a link; recent UK studies indicate that peers and relatives may be far more important to boys than their teachers. Given the seemingly relentless reference to male teachers as role models…

Consequences of Team Job Demands: Role Ambiguity Climate, Affective Engagement, and Extra-Role Performance

In the absence of clearly established procedures in the workplace, employees will experience a negative affective state. This situation influences their well-being and their intention to behave in ways that benefit the organization beyond their job demands. This impact is more relevant on teamwork where members share the perception of ambiguity through emotional contagion (role ambiguity climate). In the framework of the job demands-resources model, the present study analyzes how high levels of role ambiguity climate can have such an effect to reduce employee affective engagement. Over time it has been associated with negative results for the organization due to a lack of extra-role performance. The sample included 706 employees from a multinational company, who were divided into 11 work teams. In line with the formulated hypotheses, the results confirm the negative influence of the role ambiguity climate on extra-role performance, and the mediated effect of affective engagement in the relationship between the role ambiguity climate and extra-role performance. These findings indicate that the role ambiguity climate is related to the adequate or inadequate functioning of employees within a work context. PMID:29375424

Resident Role Modeling: "It Just Happens".

Role modeling by staff physicians is a significant component of the clinical teaching of students and residents. However, the importance of resident role modeling has only recently emerged, and residents' understanding of themselves as role models has yet to be explored. This study sought to understand residents' perceptions of themselves as role models, describe how residents learn about role modeling, and identify ways to improve resident role modeling. Fourteen semistructured interviews were conducted with residents in internal medicine, general surgery, and pediatrics at the McGill University Faculty of Medicine between April and September 2013. Interviews were audio-recorded and subsequently transcribed for analysis; iterative analysis followed principles of qualitative description. Four primary themes were identified through data analysis: residents perceived role modeling as the demonstration of "good" behaviors in the clinical context; residents believed that learning from their role modeling "just happens" as long as learners are "watching"; residents did not equate role modeling with being a role model; and residents learned about role modeling from watching their positive and negative role models. While residents were aware that students and junior colleagues learned from their modeling, they were often not aware of role modeling as it was occurring; they also believed that learning from role modeling "just happens" and did not always see themselves as role models. Helping residents view effective role modeling as a deliberate process rather than something that "just happens" may improve clinical teaching across the continuum of medical education.

Aggression in the workplace is increasingly recognized as a serious problem, but there are few studies about worker aggression toward outsiders in the workplace. We investigated the association between aggression and occupational stress among teachers. This was a cross-sectional study of 1583 teachers, principals, and vice-principals. Aggression was measured using the Japanese version of the Buss-Perry Aggression Questionnaire (BAQ). The survey respondents were classified into tertiles according to the BAQ score. The high BAQ group was defined as the upper tertile for the BAQ total score (BAQ total score 625). Occupational stress was measured using the Japanese version of the Generic Job Stress Questionnaire. Comparisons among the groups were performed using multiple logistic regression analysis. Of the 1583 respondents, 488 were included in the high BAQ group. After adjusting for demographic and occupational variables, high role conflict and role ambiguity were significantly associated with belonging to the high BAQ group. In subscales of the BAQ, high role conflict and role ambiguity related to high levels of hostility, and physical aggression. Occupational stress such as role conflict and role ambiguity was associated with aggression among teachers. It is necessary to reduce problems which relates to role conflict and role ambiguity for preventing teachers' aggression.

Mining Stable Roles in RBAC

NASA Astrophysics Data System (ADS)

Colantonio, Alessandro; di Pietro, Roberto; Ocello, Alberto; Verde, Nino Vincenzo

In this paper we address the problem of generating a candidate role-set for an RBAC configuration that enjoys the following two key features: it minimizes the administration cost; and, it is a stable candidate role-set. To achieve these goals, we implement a three steps methodology: first, we associate a weight to roles; second, we identify and remove the user-permission assignments that cannot belong to a role that have a weight exceeding a given threshold; third, we restrict the problem of finding a candidate role-set for the given system configuration using only the user-permission assignments that have not been removed in the second step—that is, user-permission assignments that belong to roles with a weight exceeding the given threshold. We formally show—proof of our results are rooted in graph theory—that this methodology achieves the intended goals. Finally, we discuss practical applications of our approach to the role mining problem.

CNS role evolution.

Payne, J L; Baumgartner, R G

1996-01-01

THE CNS ROLE has been actualized in a variety of ways. Flexibility-inherent in the role-and the revolution in health care consciousness tend to place the CNS at risk for criticism regarding value to the organization. At Vanderbilt University Medical Center, a CNS task force evaluated the current reality of CNS practice and recommended role changes to include the financial analysis of patient care. After incorporating a financial perspective into our present practice, we have embarked on an interesting journey of post-Master's degree study, that of the tertiary care nurse practitioner. This practice option could elevated the clinical and financial aspects of providing cost-effective health care to a more autonomous role form; however, the transition has been challenging. Since 1990, the American Nurses Association has recommended that nursing school curricula change to meet the needs of the health care environment and provide increased career flexibility through creating one advanced degree incorporating both CNS and NP functions. Swiftly moving past differences and toward similarities will bridge the gap for advanced practice nurses in the future.

Biological roles of glycans

PubMed Central

Varki, Ajit

2017-01-01

Abstract Simple and complex carbohydrates (glycans) have long been known to play major metabolic, structural and physical roles in biological systems. Targeted microbial binding to host glycans has also been studied for decades. But such biological roles can only explain some of the remarkable complexity and organismal diversity of glycans in nature. Reviewing the subject about two decades ago, one could find very few clear-cut instances of glycan-recognition-specific biological roles of glycans that were of intrinsic value to the organism expressing them. In striking contrast there is now a profusion of examples, such that this updated review cannot be comprehensive. Instead, a historical overview is presented, broad principles outlined and a few examples cited, representing diverse types of roles, mediated by various glycan classes, in different evolutionary lineages. What remains unchanged is the fact that while all theories regarding biological roles of glycans are supported by compelling evidence, exceptions to each can be found. In retrospect, this is not surprising. Complex and diverse glycans appear to be ubiquitous to all cells in nature, and essential to all life forms. Thus, >3 billion years of evolution consistently generated organisms that use these molecules for many key biological roles, even while sometimes coopting them for minor functions. In this respect, glycans are no different from other major macromolecular building blocks of life (nucleic acids, proteins and lipids), simply more rapidly evolving and complex. It is time for the diverse functional roles of glycans to be fully incorporated into the mainstream of biological sciences. PMID:27558841

Aggression toward gay men as gender role enforcement: effects of male role norms, sexual prejudice, and masculine gender role stress.

Parrott, Dominic J

2009-08-01

This study examined sexual prejudice and masculine gender role stress as mediators of the relations between male gender norms and anger and aggression toward gay men. Participants were 150 self-identified heterosexual men who completed measures of adherence to male gender role norms, sexual prejudice, masculine gender role stress, and state anger. Participants then viewed a video depicting intimate relationship behavior between 2 gay men, reported state anger a second time, and competed in a laboratory aggression task against either a heterosexual or a gay male. Results indicated that adherence to the antifemininity norm exerted an indirect effect, primarily through sexual prejudice, on increases in anger. Adherence to the status and antifemininity norms exerted indirect effects, also through sexual prejudice, on physical aggression toward the gay, but not the heterosexual, male. Findings provide the first multivariate evidence for determinants of aggression toward gay men motivated by gender role enforcement.

Atom-Role-Based Access Control Model

Cai, Weihong; Huang, Richeng; Hou, Xiaoli; Wei, Gang; Xiao, Shui; Chen, Yindong

Role-based access control (RBAC) model has been widely recognized as an efficient access control model and becomes a hot research topic of information security at present. However, in the large-scale enterprise application environments, the traditional RBAC model based on the role hierarchy has the following deficiencies: Firstly, it is unable to reflect the role relationships in complicated cases effectively, which does not accord with practical applications. Secondly, the senior role unconditionally inherits all permissions of the junior role, thus if a user is under the supervisor role, he may accumulate all permissions, and this easily causes the abuse of permission and violates the least privilege principle, which is one of the main security principles. To deal with these problems, we, after analyzing permission types and role relationships, proposed the concept of atom role and built an atom-role-based access control model, called ATRBAC, by dividing the permission set of each regular role based on inheritance path relationships. Through the application-specific analysis, this model can well meet the access control requirements.

Background: Traditionally, pharmacy technicians have worked alongside pharmacists in community and hospital pharmacy. Changes within pharmacy provide opportunity for role expansion and with no apparent career pathway, there is a need to define the current pharmacy technician role and role in medicines optimisation. Aim: To capture the current roles of pharmacy technicians and identify how their future role will contribute to medicines optimisation. Methods: Following ethical approval and piloting, an online survey to ascertain pharmacy technicians’ views about their roles was undertaken. Recruitment took place in collaboration with the Association of Pharmacy Technicians UK. Data were exported to SPSS, data screened and descriptive statistics produced. Free text responses were analysed and tasks collated into categories reflecting the type of work involved in each task. Results: Responses received were 393 (28%, n = 1380). Results were organised into five groups: i.e., hospital, community, primary care, General Practitioner (GP) practice and other (which included HM Prison Service). Thirty tasks were reported as commonly undertaken in three or more settings and 206 (84.7%, n = 243) pharmacy technicians reported they would like to expand their role. Conclusions: Tasks core to hospital and community pharmacy should be considered for inclusion to initial education standards to reflect current practice. Post qualification, pharmacy technicians indicate a significant desire to expand clinically and managerially allowing pharmacists more time in patient-facing/clinical roles. PMID:28970452

A study of role expansion: a new GP role in cardiology care

PubMed Central

2014-01-01

Background The National Health Service is reconfiguring health care services in order to meet the increasing challenge of providing care for people with long-term conditions and to reduce the demand on specialised outpatient hospital services by enhancing primary care. A review of cardiology referrals to specialised care and the literature on referral management inspired the development of a new GP role in Cardiology. This new extended role was developed to enable GPs to diagnose and manage patients with mild to moderate heart failure or atrial fibrillation and to use a range of diagnostics effectively in primary care. This entailed GPs participating in a four-session short course with on-going clinical supervision. The new role was piloted in a small number of GP practices in one county in England for four months. This study explores the impact of piloting the Extended Cardiology role on the GP’s role, patients’ experience, service delivery and quality. Methods A mixed methods approach was employed including semi-structured interviews with GPs, a patient experience survey, a quality review of case notes, and analysis on activity and referral data. Results The participating GPs perceived the extended GP role as a professional development opportunity that had the potential to reduce healthcare utilisation and costs, through a reduction in referrals, whilst meeting the patient’s wishes for the provision of care closer to home. Patient experience of the new GP service was positive. The standard of clinical practice was judged acceptable. There was a fall in referrals during the study period. Conclusion This new role in cardiology was broadly welcomed as a model of care by the participating GPs and by patients, because of the potential to improve the quality of care for patients in primary care and reduce costs. As this was a pilot study further development and continuing evaluation of the model is recommended. PMID:24885826

Beyond common features: The role of roles in determining similarity1

PubMed Central

Jones, Matt; Love, Bradley C.

2007-01-01

Historically, accounts of object representation and perceived similarity have focused on intrinsic features. Although more recent accounts have explored how objects, scenes, and situations containing common relational structures come to be perceived as similar, less is known about how the perceived similarity of parts or objects embedded within these relational systems is affected. The current studies test the hypothesis that objects situated in common relational systems come to be perceived as more similar. Similarity increases most for objects playing the same role within a relation (e.g., predator), but also increases for objects playing different roles within the same relation (e.g., the predator or prey role in the hunts relation) regardless of whether the objects participate in the same instance of the relation. This pattern of results can be captured by extending existing models that extract meaning from text corpora so that they are sensitive to the verb-specific thematic roles that objects fill. Alternative explanations based on analogical and inferential processes are also considered, as well as the implications of the current findings to research in language processing, personality and person perception, decision making, and category learning.

2015-09-01

Ever since the first descriptions of methods to isolate pancreatic stellate cells (PSCs) from rodent and human pancreas 17 years ago, rapid advances have been made in our understanding of the biology of these cells and their functions in health and disease. This review updates recent literature in the field, which indicates an increasingly complex role for the cells in normal pancreas, pancreatitis and pancreatic cancer. Work reported over the past 12 months includes improved methods of PSC immortalization, a role for PSCs in islet fibrosis, novel factors causing PSC activation as well as those inducing quiescence, and translational research aimed at inhibiting the facilitatory effects of PSCs on disease progression in chronic pancreatitis as well as pancreatic cancer. Improved understanding of the role of PSCs in pancreatic pathophysiology has prompted a focus on translational studies aimed at developing novel approaches to modulate PSC function in a bid to improve clinical outcomes of two major fibrotic diseases of the pancreas: chronic pancreatitis and pancreatic cancer.

Influence of ownership type on role orientation, role affinity, and role conflict among community pharmacy managers and owners in Canada.

2010-12-01

Ownership of community pharmacies is increasingly being controlled by a relatively small number of corporate entities. The influence of this ownership type should not be ignored, because ownership has the ability to impact pharmacy practice. To examine the relationship between ownership type and community pharmacy managers with regard to role orientation, role affinity, and role conflict. This study consisted of a cross-sectional survey of community pharmacy managers in Canada by means of a self-administered postal questionnaire sent to a stratified sample of community pharmacies. Statistical analysis consisted of exploratory factor analysis with reliability testing on identified constructs. Frequencies, 1-way analyses of variance, and Scheffe post hoc tests were used to determine significant differences among groups, including ownership structure, on each of the constructs. A total of 646 completed questionnaires were received (32.9% response rate). Most of the respondents were males (60.8%), with slightly less than half of the respondents identifying their practice type as an independent pharmacy (44.6%). There were 5 multi-item scale constructs (professional orientation, business orientation, professional affinity, business affinity, and role conflict) arising from the data, which were analyzed against the pharmacy ownership structure (independent, franchise, corporate) independent variable. Analysis revealed significant differences for 3 of the 5 constructs; however, no differences were seen regarding the 2 professionally focused constructs. Community pharmacy managers/owners are generally oriented to their professional role; however, those working in a corporate pharmacy environment are less oriented to their business role when compared with those working in an independent or franchise pharmacy environment. Further research is needed to identify different practice cultures that may exist in various practice settings and the extent to which these cultures

Data-mining to build a knowledge representation store for clinical decision support. Studies on curation and validation based on machine performance in multiple choice medical licensing examinations.

PubMed

Robson, Barry; Boray, Srinidhi

2016-06-01

Extracting medical knowledge by structured data mining of many medical records and from unstructured data mining of natural language source text on the Internet will become increasingly important for clinical decision support. Output from these sources can be transformed into large numbers of elements of knowledge in a Knowledge Representation Store (KRS), here using the notation and to some extent the algebraic principles of the Q-UEL Web-based universal exchange and inference language described previously, rooted in Dirac notation from quantum mechanics and linguistic theory. In a KRS, semantic structures or statements about the world of interest to medicine are analogous to natural language sentences seen as formed from noun phrases separated by verbs, prepositions and other descriptions of relationships. A convenient method of testing and better curating these elements of knowledge is by having the computer use them to take the test of a multiple choice medical licensing examination. It is a venture which perhaps tells us almost as much about the reasoning of students and examiners as it does about the requirements for Artificial Intelligence as employed in clinical decision making. It emphasizes the role of context and of contextual probabilities as opposed to the more familiar intrinsic probabilities, and of a preliminary form of logic that we call presyllogistic reasoning.

The literature has seen a surge in research on the mental health impacts of technologies such as Facebook, video games, and massively-multiplayer online role-playing games such as World of Warcraft, but little is known regarding the mental health impact of non-video role-playing games, such as Dungeons & Dragons. The present study examines how psychiatrists' perceive role-playing games and whether they play them. Psychiatrists at a tertiary care centre in Canada completed a questionnaire assessing history of playing role-playing games and whether they associate them with psychopathology. Forty-eight psychiatrists responded. Twenty-three percent have played a role-playing game over their lifetimes. Twenty-two percent believed there was an association between psychopathology and role-playing games. A majority of psychiatrists who responded do not associate role-playing games with psychopathology. Implications for clinical practice and future research are discussed.

The purpose of the program is to provide the engineering community with a centralized database for entering and accessing system functional definitions, subsystem and instrument-end circuit pinout details, and harnessing data. The primary objective is to provide an instantaneous single point of information interchange, thus avoiding error-prone, time-consuming, and costly multiple-path data shuttling. The DFACS program, which is centered around a single database, has built-in menus that provide easy data input and access for all involved system, subsystem, and cabling personnel. The DFACS program allows parallel design of circuit data sheets and harness drawings. It also recombines raw information to automatically generate various project documents and drawings including the Circuit Data Sheet Index, the Electrical Interface Circuits List, Assembly and Equipment Lists, Electrical Ground Tree, Connector List, Cable Tree, Cabling Electrical Interface and Harness Drawings, Circuit Data Sheets, and ECR List of Affected Interfaces/Assemblies. Real time automatic production of harness drawings and circuit data sheets from the same data reservoir ensures instant system and cabling engineering design harmony. DFACS also contains automatic wire routing procedures and extensive error checking routines designed to minimize the possibility of engineering error. DFACS is designed to run on DEC VAX series computers under VMS using Version 6.3/01 of INGRES QUEL/OSL, a relational database system which is available through Relational Technology, Inc. The program is available in VAX BACKUP format on a 1600 BPI 9-track magnetic tape (standard media) or a TK50 tape cartridge. DFACS was developed in 1987 and last updated in 1990.

Daigle, Leah E; Mummert, Sadie J

2014-01-01

Although sex-role identification has been found to be associated with crime and delinquency, the link between sex-role identification and violent victimization has remained largely unexplored. Using the Add Health data, this study examines sex-role identification and its relationship to violent victimization. The findings suggest that masculinity increases the risk of violent victimization for males, but does not for females. Other differences in risk factors across gender were also found. These findings indicate that masculinity is an important construct in understanding the complexity of why some persons are violently victimized and others are not.

Most studies about multiple roles and women's health suggested that combining with paid job, being married and having children was more likely to improve health status than in case of single or traditional roles. We investigated whether there was better health outcome in multiple roles among Korean women coinciding with previous studies of other nations. Data were from the 2005 Korea National Health & Nutritional Examination Survey, a subsample of women aged 25-59 years (N=2,943). Health status was assessed for self-rated poor health, perceived stress and depression, respectively based on one questionnaire item. The age-standardized prevalence of all health outcomes were calculated by role categories and socioeconomic status. Multiple logistic regression was used to assess the association of self rated health, perceived stress, and depression with multiple roles adjusted for age, education, household income, number of children and age of children. Having multiple roles with working role was not associated with better health and psychological wellbeing. Compared to those with traditional roles, employed women more frequently experienced perceived stress, with marital and/or parental roles. Non-working single mothers suffered depression more often than women with traditional roles or other role occupancy. Socioeconomic status indicators were potent independent correlates of self-rated health and perceived stress. Employment of women with other roles did not confer additional health benefit to traditional family responsibility. Juggling of work and family responsibility appeared more stressful than traditional unemployed parental and marital role in Korean women.

Purewal, Satvinder; Crawshaw, Marilyn; van den Akker, Olga

2012-06-01

This study investigated the attitudes of parental order reporters (PORs) towards their work with surrogacy arrangements and their experiences of role conflict and role ambiguity. A questionnaire was used to assess PORs' perceptions of their role in parental order [PO] applications, attitudes towards surrogacy arrangements and the legal process and the influence of role ambiguity or conflict. Questionnaires were distributed to all PORs employed by the Children and Family Court Advisory and Support Service in England. Thirty-three PORs participated (response rate 46%) who, on average, had each completed five PO applications (range 1-40). Positive attitudes towards surrogacy and the child's needs for openness about origins were found. Concerns about the inadequacy of preparation and assessment arrangements, overseas arrangements and non-regulation of surrogacy agencies were evident. PORs with high-role ambiguity were more likely to report less positive attitudes towards the emotional consequence of surrogacy on offspring. High scores on role ambiguity and role conflict were reflected in less positive attitudes towards the parties' preparation towards parenthood. These results have implications for training, policy and practice in this area.

The authors propose that competence need fulfillment within valued role domains (i.e., spouse, parent, worker) will account, in part, for associations between autonomy and relatedness need fulfillment and psychological health. Testing these assertions in cross-sectional and longitudinal surveys of women in two independent community samples, the findings are the first to formally examine whether the satisfaction of competence needs within social roles accounts for associations between other types of need satisfaction and affective outcomes as well as depressive symptomology. Evidence supporting the hypothesis was stronger when examining individuals’ affective health as compared to their depressive symptoms. Implications of the findings are discussed with regard to need fulfillment within social roles. PMID:22215698

To quantify the risk for delivering care at Role 1 in the Land Environment (point of wounding to hospital care) on current operations and set the conditions for systematic change to enhance future capability. UK, US and Danish Army Role 1 Subject Matter Experts (SMEs) (1) Questionnaire study ofUK SMEs to determine capability gaps; (2) Questionnaire study of US and Danish SMEs to benchmark UK capability; (3) Semi-structured interviews of UK SMEs; (4) In-theatre evaluation of deployed Role 1. Thirty two SMEs completed the questionnaire (68% response rate), comprising 25 medical officers (20 in clinical appointments; five in command and staff appointments), six nurses and one medical support officer. Results of the entire review were collated as a cross-Defence Lines of Development analysis, separating the specific experience of 1 Medical Regiment's Hybrid Foundation Training (HFT), Mission Specific Training (MST) and deployment cycle from the analysis gained from questionnaire studies, SME consultation and documentary evidence. The review generated 77 recommendations and 38 sub-recommendations. The top six messages of the review were (1) To balance the expressed desire to increase the ratio of trained Team Medics with the reality of generating credible instructors with clinical experience; (2) To recognise that inadequate experience for Combat Medical Technicians in Primary Healthcare in the Firm Base undermines their operational preparedness; (3) To recognise that Current Regimental Aid Post (RAP) at contingency without power lacks the rudimentary infrastructure of a modern Medical Treatment Facility; (4) To recognise that inappropriate deployment of personnel with chronic disease or acutely limiting conditions is a consistent trend for 20 years that highlights continuing system weaknesses in applying protective medical grading; (5) To accept that General Practitioner manning requires re-evaluating as an Operational Pinch Point, reviewing all options to maintain

Using role play to develop cultural competence.

PubMed

Shearer, Ruth; Davidhizar, Ruth

2003-06-01

Role play is a useful teaching strategy for nursing education. This strategy can simulate patient behaviors, as well as demonstrate nursing interventions that students must learn to be clinically competent. Role play is a dramatic technique that encourages participation to improvise behaviors that may be encountered in nurse-patient situations. Using this technique, participants may test behaviors and decisions in an experimental atmosphere without risk of negative effects in a relationship. Role play is useful in developing cultural competence because participants may experience diverse roles. Cultural competence is the ability to care for patients in a culturally sensitive and appropriate manner. In role play, students may participate as culturally diverse patients or as nurses encountering patients from different cultures. Various teaching strategies facilitate successful use of role play in the classroom, including defining a time frame, selected roles, specific objectives, references, and grading criteria. To optimize learning, the importance of exploration and analysis must be emphasized. Many benefits and potential problems accompany use of role play.

The importance of workplace friendship is recognized by researchers and practitioners, but its antecedents with respect to work roles are not well understood. Employees' gender might moderate a relationship between work roles and friendships. Data from a survey of 221 international tourist hotel employees showed that a key aspect of job support, role ambiguity, was negatively related to having workplace friendships. However, employees' gender did not moderate this relationship. Role clarity (the opposite of role ambiguity) may facilitate workplace friendships.

There has been interest in the relationship between homosexuality, gender role and suicide risk. Though homosexuals are more likely to identify as cross-gender, research has not simultaneously examined sexual orientation and gender role in assessing suicide risk. In the current study, the unique and interactive effects of sexual orientation and gender role were assessed in regard to suicidal ideation, related psychopathology and measures of coping. 77 participants were recruited from an undergraduate psychology subject pool (n=47) or from gay, lesbian and transgender student organizations (n=30) and assessed on measures of gender role, homosexuality, and psychopathology. Consistent with expectations, cross-gender role (i.e., personality traits associated with the opposite sex) is a unique predictor of suicidal symptoms. Moreover, gender role accounted for more of the overall variance in suicidal symptoms, positive problem orientation, peer acceptance and support, than sexual orientation. After accounting for gender role, sexual orientation contributed little to the variance in suicidal symptoms, associated pathology and problem-solving deficits. There was no support for gender role by sexual orientation interaction effects. The cross-sectional nature of the data limits statements regarding causality. Cross-gendered individuals, regardless of sexual orientation, appear to have higher risk for suicidal symptoms. Researchers and clinicians should assess gender role in evaluations of youth samples.

A case study of nurse practitioner role implementation in primary care: what happens when new roles are introduced?

PubMed Central

2013-01-01

Background At the time of this study (2009) the role of the nurse practitioner was new to the province of British Columbia. The provincial government gave the responsibility for implementing the role to health authorities. Managers of health authorities, many of whom were unfamiliar with the role, were responsible for identifying the need for the NP role, determining how the NP would function, and gaining team members’ acceptance for the new role. Method The purpose of the study was to explain the process of nurse practitioner role implementation as it was occurring and to identify factors that could enhance the implementation process. An explanatory, single case study with embedded units of analysis was used. The technique of explanation building was used in data analysis. Three primary health care settings in one health authority in British Columbia were purposively selected. Data sources included semi-structured interviews with participants (n=16) and key documents. Results The results demonstrate the complexity of implementing a new role in settings unfamiliar with it. The findings suggest that early in the implementation process and after the nurse practitioner was hired, team members needed to clarify intentions for the role and they looked to senior health authority managers for assistance. Acceptance of the nurse practitioner was facilitated by team members’ prior knowledge of either the role or the individual nurse practitioner. Community health care providers needed to be involved in the implementation process and their acceptance developed as they gained knowledge and understanding of the role. Conclusion The findings suggest that the interconnectedness of the concepts of intention, involvement and acceptance influences the implementation process and how the nurse practitioner is able to function in the setting. Without any one of the three concepts not only is implementation difficult, but it is also challenging for the nurse practitioner to fulfill

Role congruity theory of prejudice toward female leaders.

PubMed

Eagly, Alice H; Karau, Steven J

2002-07-01

A role congruity theory of prejudice toward female leaders proposes that perceived incongruity between the female gender role and leadership roles leads to 2 forms of prejudice: (a) perceiving women less favorably than men as potential occupants of leadership roles and (b) evaluating behavior that fulfills the prescriptions of a leader role less favorably when it is enacted by a woman. One consequence is that attitudes are less positive toward female than male leaders and potential leaders. Other consequences are that it is more difficult for women to become leaders and to achieve success in leadership roles. Evidence from varied research paradigms substantiates that these consequences occur, especially in situations that heighten perceptions of incongruity between the female gender role and leadership roles.

The Morphogenetic Role of Apoptosis.

PubMed

Monier, Bruno; Suzanne, Magali

2015-01-01

Beyond safeguarding the organism from cell misbehavior and controlling cell number, apoptosis (or programmed cell death) plays key roles during animal development. In particular, it has long been acknowledged that apoptosis participates in tissue remodeling. Yet, until recently, this contribution to morphogenesis was considered as "passive," consisting simply in the local removal of unnecessary cells leading to a new shape. In recent years, applying live imaging methods to study the dynamics of apoptosis in various contexts has considerably modified our vision, revealing that in fact, dying cells remodel their neighborhood actively. Here, we first focus on the intrinsic cellular properties of apoptotic cells during their dismantling, in particular the role of the cytoskeleton during their characteristic morphological changes. Second, we review the various roles of apoptosis during developmental morphogenetic processes and pinpoint the crucial role of live imaging in revealing new concepts, in particular apoptosis as a generator of mechanical forces to control tissue dynamics. © 2015 Elsevier Inc.

2011-03-01

There has been a rapid growth of online teaching in the past few years, yet the implementation of role-play for formal educational activities in an online setting is growing more slowly. The use of online role-playing for the development of health professions educators is virtually un-documented in the literature. In the project reported here we use role-playing as a method to motivate and increase active participation in an online web-based discussion on community-based medical education (CBME). The Foundation for Advancement of International Medical Education & Research (FAIMER(®) ) Institute hosts virtual group discussions for fellows as part of its fellowship programmes, in order to deepen their knowledge base in health professions education and research. In June 2008, a group of seven FAIMER(®) fellows and faculty members moderated an online discussion on CBME using an online role-play exercise with other fellows and faculty members. Out of a total of 102 fellows, 36 (35.3%) participated actively, which exceeded the typical percentage of list server participation. In addition, a rich discussion resulted in a comprehensive report on the goals, challenges, logistical components, role of Health Ministry policy and the possible ethical mandate of CBME in developing countries. Online role-play encouraged distributed participation among a highly diverse international group of participants, supporting the conclusion that role-playing can be used effectively with mid-career health professional faculty members in the online environment. © Blackwell Publishing Ltd 2011.

Linking perceptions of role stress and incivility to workplace aggression: the moderating role of personality.

PubMed

Taylor, Shannon G; Kluemper, Donald H

2012-07-01

Although research on workplace aggression has long recognized job stressors as antecedents, little is known about the process through which employee responses to stressful workplace demands escalate from relatively mild interactions into more intense behaviors. This study investigates the influence that employees' perceptions of role stress (ambiguity, conflict, overload) have on their aggressive behavior by affecting their perceptions of incivility, and whether these downstream effects depend on personality traits (neuroticism, agreeableness, conscientiousness). Results supported moderated mediation, such that the indirect effects of perceived role ambiguity and role conflict on enacted aggression through experienced incivility varied according to individual differences in personality.

Gender Role Violations and the Sexual Double Standard.

PubMed

Zaikman, Yuliana; Marks, Michael J; Young, Tara M; Zeiber, Jacqueline A

2016-12-01

The sexual double standard (SDS) suggests that women are evaluated negatively and men positively for engaging in similar sexual behaviors. According to social role theory, the SDS exists due to gender role structures. Consequently, perceived violations of women's sexual behavior are associated with the SDS. In addition to gender role violations of sexual behavior, two additional violations of gender roles exist: heterosexual sexual orientation norms and gender role characteristics. The current study aims to investigate whether the SDS persists for sexual orientation-violating and gender role characteristic-violating targets, and to examine which of the three gender role violations influence evaluations of others' sexual behavior. A U.S. sample of 483 participants evaluated target individuals who were either female or male, heterosexual/gay man or lesbian, feminine or masculine, and had 1 or 12 sexual partners. Results indicate that SDS persists for gender role-violating targets but is exhibited differently for targets violating heterosexual sexual orientation norms and gender role characteristics.

Role perceptions of divorcing parents.

Fishel, A H; Samsa, G P

1993-01-01

Using interview data from a convenience sample of 101 divorcing parents, we examined the gender roles of parents during the transition from marriage to divorce. We found that the women, who most often initiated divorce, were changing their roles and that this was related to marital dissatisfactions. Factor analysis indicated that real differences existed in how mothers and fathers perceived the co-parental relationship. Mothers saw the relationship as supportive at times and conflictual at times. Fathers tended to view the relationship as helpful only if it did not contain conflict. Improved communication in the coparental relationship after divorce seemed to be related to changes in traditional female and male roles.

Hyaluronic acid: its role in voice.

2002-09-01

The extracellular matrix (ECM), once regarded simply as a structural scaffold, is now recognized as an important modulator of cellular behavior and function. One component that plays a prominent role in this process is hyaluronic acid (HA)--a molecule found in many different tissues. Research into the roles of HA indicates that it plays a key role in tissue viscosity, shock absorption, and space filling. Specifically, research into the role of HA in laryngology indicates that it has profound effects on the structure and viscosity of vocal folds. This article provides an introduction to the structure and biological functions of HA and its importance in voice. In addition, an overview of the pharmaceutical applications of HA is discussed.

Rapidly increasing amounts of (physical and genetic) protein-protein interaction (PPI) data are produced by various high-throughput techniques, and interpretation of these data remains a major challenge. In order to gain insight into the organization and structure of the resultant large complex networks formed by interacting molecules, using simulated annealing, a method based on the node connectivity, we developed ModuleRole, a user-friendly web server tool which finds modules in PPI network and defines the roles for every node, and produces files for visualization in Cytoscape and Pajek. For given proteins, it analyzes the PPI network from BioGRID database, finds and visualizes the modules these proteins form, and then defines the role every node plays in this network, based on two topological parameters Participation Coefficient and Z-score. This is the first program which provides interactive and very friendly interface for biologists to find and visualize modules and roles of proteins in PPI network. It can be tested online at the website http://www.bioinfo.org/modulerole/index.php, which is free and open to all users and there is no login requirement, with demo data provided by "User Guide" in the menu Help. Non-server application of this program is considered for high-throughput data with more than 200 nodes or user's own interaction datasets. Users are able to bookmark the web link to the result page and access at a later time. As an interactive and highly customizable application, ModuleRole requires no expert knowledge in graph theory on the user side and can be used in both Linux and Windows system, thus a very useful tool for biologist to analyze and visualize PPI networks from databases such as BioGRID. ModuleRole is implemented in Java and C, and is freely available at http://www.bioinfo.org/modulerole/index.php. Supplementary information (user guide, demo data) is also available at this website.

Linking transformational leadership to nurses' extra-role performance: the mediating role of self-efficacy and work engagement.

Salanova, Marisa; Lorente, Laura; Chambel, Maria J; Martínez, Isabel M

2011-10-01

This paper is a report of a social cognitive theory-guided study about the link between supervisors' transformational leadership and staff nurses' extra-role performance as mediated by nurse self-efficacy and work engagement. Past research has acknowledged the positive influence that transformational leaders have on employee (extra-role) performance. However, less is known about the psychological mechanisms that may explain the links between transformational leaders and extra-role performance, which encompasses behaviours that are not considered formal job requirements, but which facilitate the smooth functioning of the organization as a social system. Seventeen supervisors evaluated nurses' extra-role performance, the data generating a sample consisting of 280 dyads. The nurses worked in different health services in a large Portuguese hospital and the participation rate was 76·9% for nurses and 100% for supervisors. Data were collected during 2009. A theory-driven model of the relationships between transformation leadership, self-efficacy, work engagement and nurses' extra-role performance was tested using Structural Equation Modelling. Data analysis revealed a full mediation model in which transformational leadership explained extra-role performance through self-efficacy and work engagement. A direct relationship between transformational leadership and work engagement was also found. Nurses' supervisors with a transformational leadership style enhance different 'extra-role' performance in nurses and this increases hospital efficacy. They do so by establishing a sense of self-efficacy but also by amplifying their levels of engagement in the workplace. © 2011 Blackwell Publishing Ltd.

2013-03-01

The NSW Health Policy Directive (NSW Department of Health, 2000) lists clinical service and consultancy; clinical leadership; research; education; clinical services planning and management as the five domains of practice for nurses appointed as Clinical Nurse Consultants (CNCs), an Australian advanced practice nurse (APN) role. However, there is no clear definition of what is meant by advanced practice in the Australian nursing context. Nowhere is this more evident than in differentiating between the roles of Clinical Nurse Consultants (CNCs) and Nurse Practitioners (NP) in NSW. To date, limited empirical research has been done to characterise or delineate CNC role activity and responsibility. To investigate (i) the nature of CNC roles, activities and responsibilities, (ii) differentiate between CNCs by their work patterns and activities, and (iii) empirically conceptualize and differentiate ways CNCs practice in terms of an APN typology. The study sample was 56 CNCs at one tertiary level public hospital in Australia. A descriptive exploratory cohort study was conducted to explore CNC role characteristics and patterns of activity. Data were triangulated using an online survey, a follow-up survey, and semi-structured interviews. The data were analysed using descriptive statistics to examine differences between CNC work patterns and role activities. The survey data and the individual reports were thematically analysed to investigate for difference across the population of CNCs. Interpretation of survey and interview data led to an analyst-developed CNC typology of four CNC categories based on the work patterns and activities of Sole Practitioner, Clinic Coordinator, Clinical Team Coordinator and Clinical Leader. The typology was based on the themes interprofessional, role focus, clinical focus and setting as these themes distinguished and differentiated CNC roles. The study provides evidence of great diversity and prioritization within CNC roles. The CNC typology

2010-01-01

The Department of Defense (000) has successfully applied a number of methods for cultural familiarization training ranging from stand-up classroom training, to face-to-face live role-play, to so-called smart-cards. Recent interest has turned to the use of single and mUlti-player gaming technologies to augment these traditional methods of cultural familiarization. One such system, termed CulturePad, has been designed as a game-based role-play environment suitable for use in training and experimentation involving cultural roleplay scenarios. This paper describes the initial CulturePad effort focused on a literature review regarding the use of role-play for cultural training and a feasibility assessment of using a game-mediated environment for role-play. A small-scale pilot involving cultural experts was conducted to collect qualitative behavioral data comparing live role-play to game-mediated role-play in a multiplayer gaming engine.

Male to female: the role transformation of transsexuals.

PubMed

Levine, E M; Shaiova, C H; Mihailovic, M

1975-03-01

Twelve male transsexuals were found to have acquired a successtion of gender roles from childhood to adulthood-ambivalent, homosexual, drag queen, and transsexual. Thse roles constituted different stages of their livers during which they were clarifying their psychosocial gender role as transsexuals. Their transition through these roles suggests that these individuals are a subset of the transsexual phenomenon, for many--probably most--other transsexuals do not adopt these roles prior to becoming adult transsexuals. The social interaction of these transsexuals with significant others differed from the ways in which sociological role theories view this process: the significant others in their lives (apart from their mothers) primarily influenced their role changes by withdrawing from and/or rejecting these individuals--not by inducing them to conform to their role expectations. As permanently cross-dressed transsexuals, these individuals continued to associate with the institutions of the gay world, which alone was tolerant of them and where they could draw on the emotional support of other transsexuals in this last presurgery role. At this point they had become their own reference group.

The part-time student role: implications for the emotional experience of managing multiple roles amongst Hong Kong public health nurses.

PubMed

Shiu, A T

1999-04-01

The study investigated the contribution of the added part-time student role on the emotional experience of managing multiple roles of Hong Kong public health nurses (PHNs) who have children by comparing PHNs with and without the part-time student role. The research design employed the experience sampling method. Convenience sampling was used to recruit 20 subjects of which nine were undertaking part-time degree programmes. A watch was worn that gave a signal at six random times each day for 7 days to complete an experience sampling diary. PHNs on average responded to 34 signals (80%) and therefore completed 34 diaries, which collected data on work, college-work and family juggling and their effects on mood states. Results indicate that PHNs with an added part-time student role, although having fewer juggling occasions and higher emotional spouse support, had fewer family-related activities as well as a lower positive effect and a higher negative effect than PHNs without this role. These results suggest that taking up an added part-time student role creates additional role strain to nurses with children, and lend support to the argument that the stress of managing multiple roles is greatest and benefits least when work and non-work role responsibilities are both heavy.

Teaching clinical interviewing skills using role-playing: conveying empathy to performing a suicide assessment: a primer for individual role-playing and scripted group role-playing.

PubMed

Shea, Shawn Christopher; Barney, Christine

2015-03-01

This article provides a useful introduction to the art of role-playing in both the individual format and the group format using scripted group role-playing (SGRP). Role-playing can provide powerful learning opportunities, but to do so it must be done well. This article imparts guidance toward this goal. SGRP may greatly enhance the acquisition of critical complex interviewing skills, such as suicide assessment and uncovering domestic violence, in health care providers across all disciplines, an educational goal that has not been achievable to date. Although research is at an early stage of development, the hope represented by SGRP is tangible. Copyright © 2015 Elsevier Inc. All rights reserved.

Role stress among auxiliary nurses midwives in Gujarat, India.

Purohit, Bhaskar; Vasava, Paul

2017-01-23

Understanding Role Stress is important as health service providers, especially nurses experience high levels of Role Stress which is linked to burnout, poor quality of care and high turnover. The current study explicates the concept of Role Stress and assesses the Role Stress experienced by the Auxiliary Nurse Midwives (ANMs) working with rural government health centres from Gujarat, India. The study included 84 ANMs working with government health centres from one district in India. A structured instrument with established reliability and validity was used to measure 10 dimensions of Role Stress namely: Inter-role distance, role stagnation, role expectation conflict, role erosion: role overload, role isolation, personal inadequacy, self-role distance, role ambiguity and resource inadequacy. The study instrument was based on 5 point Likert rating scale that contained 50 unidirectional negative statements, 5 for each dimension. Kolmogorov-Smirnov and Shapiro-Wilk test were carried out to assess if the data were normally distributed. Cronbach's alpha test was carried out to assess reliability of the instrument. The study data was analyzed using descriptive statistics mainly using mean scores with higher scores indicating higher Role Stress and vice versa. The data was analyzed using SPSS version 19. Kolmogorov-Smirnov and Shapiro-Wilk test indicated that the data were normally distributed. Cronbach's alpha test indicated values of 0.852 suggesting high reliability of the tool. The highest Role Stress among ANMs was experienced for resource inadequacy. Role overload, role stagnation and inter-role distance were among the other important role stressors for ANMs. The study results suggests that ANMs frequently feel that: they do not have adequate amount of resources, facilities and financial support from the high levels authorities; people have too many expectations from their roles and as result they are overloaded with work and have very limited opportunities for

Scalable and Axiomatic Ranking of Network Role Similarity

PubMed Central

Jin, Ruoming; Lee, Victor E.; Li, Longjie

2014-01-01

A key task in analyzing social networks and other complex networks is role analysis: describing and categorizing nodes according to how they interact with other nodes. Two nodes have the same role if they interact with equivalent sets of neighbors. The most fundamental role equivalence is automorphic equivalence. Unfortunately, the fastest algorithms known for graph automorphism are nonpolynomial. Moreover, since exact equivalence is rare, a more meaningful task is measuring the role similarity between any two nodes. This task is closely related to the structural or link-based similarity problem that SimRank addresses. However, SimRank and other existing similarity measures are not sufficient because they do not guarantee to recognize automorphically or structurally equivalent nodes. This paper makes two contributions. First, we present and justify several axiomatic properties necessary for a role similarity measure or metric. Second, we present RoleSim, a new similarity metric which satisfies these axioms and which can be computed with a simple iterative algorithm. We rigorously prove that RoleSim satisfies all these axiomatic properties. We also introduce Iceberg RoleSim, a scalable algorithm which discovers all pairs with RoleSim scores above a user-defined threshold θ. We demonstrate the interpretative power of RoleSim on both both synthetic and real datasets. PMID:25383066

Knowledge Management in Role Based Agents

NASA Astrophysics Data System (ADS)

Kır, Hüseyin; Ekinci, Erdem Eser; Dikenelli, Oguz

In multi-agent system literature, the role concept is getting increasingly researched to provide an abstraction to scope beliefs, norms, goals of agents and to shape relationships of the agents in the organization. In this research, we propose a knowledgebase architecture to increase applicability of roles in MAS domain by drawing inspiration from the self concept in the role theory of sociology. The proposed knowledgebase architecture has granulated structure that is dynamically organized according to the agent's identification in a social environment. Thanks to this dynamic structure, agents are enabled to work on consistent knowledge in spite of inevitable conflicts between roles and the agent. The knowledgebase architecture is also implemented and incorporated into the SEAGENT multi-agent system development framework.

Development of the Perceived Multiple Role Stress Scale (PMRS).

Gigliotti, E

2001-01-01

Assessment of women's perception of multiple-role stress arising from occupancy of the maternal and student role is crucial if we are to engage in prevention and intervention strategies. Existing measures do not fully address the components of multiple role stress in this population: emotional role ambiguity, person-role and inter-role conflict. This article describes the development of the Perceived Multiple Role Stress Scale (PMRS) which was derived from Kahn, Wolfe, Quinn and Snoek's (1964) systems-based role theory. The 8-item, 3-factor PMRS measures multiple role stress in women who are both mothers and students. Review of the PMRS by role stress and women's roles experts supported content validity. Construct validity was supported in three phases over a five-year period. It is recommended that the three correlated factors be used as one eight-item scale. The internal consistency for the PMRS was .86.

Masculine role discrepancy and discrepancy stress occur when men perceive that they fail to live up to the ideal manhood derived from societal prescriptions. The present study examined the associations between masculine role discrepancy and two emotional and mental health problems (social anxiety and depressive symptoms), and potential mediation effects through discrepancy stress and self-esteem in a male general population. Based on random population-based sampling, 2000 male residents in Hong Kong were interviewed. Levels of masculine role discrepancy, discrepancy stress, self-esteem, social anxiety, and depressive symptoms were assessed by using validated scales. Results of structural equation modeling analysis indicated that the proposed model fit the sample well. (χ 2 (118) = 832.34, p < .05, CFI = 0.94, NNFI = 0.91, RMSEA = 0.06). Those who were young, single and less educated were vulnerable to masculine role discrepancy, discrepancy stress, and emotional/mental health problems. We found that discrepancy stress significantly mediated the association between masculine role discrepancy and social anxiety, while self-esteem significantly mediated the associations between masculine role discrepancy and both social anxiety and depression. Study limitations mainly included the cross-sectional design and reliance on self-reported questionnaires. The associations between masculine discrepancy and social anxiety/depressive symptoms among men may be explained by the increase in discrepancy stress and decrease in self-esteem. The findings suggest needs and directions for future research for the relationship between masculine role discrepancy and men's mental health, mechanisms involved, and interventions for improvement.

2018-04-01

Role ambiguity is a lack of clarity or uncertainty related to one's position or role. Role ambiguity has been documented in the literature in relationship to athletics, industry, business, education, and nursing. However, a concept analysis has not been performed. Therefore, the process of concept analysis outlined by Walker and Avant is now used to look at the concept of role ambiguity and its relevance to senior nursing students' socialization and education into the profession of nursing. Attributes, antecedents, consequences, and empiric referents are discussed and theories commonly associated with role ambiguity are presented. At the end of the analysis, an operational definition is provided for use in exploring the concept of role ambiguity as it relates to senior nursing students' articulation of the role of the professional nurse. © 2017 Wiley Periodicals, Inc.

Role of vitamins in gastrointestinal diseases

Masri, Omar A; Chalhoub, Jean M; Sharara, Ala I

2015-01-01

A tremendous amount of data from research was published over the past decades concerning the roles of different vitamins in various gastrointestinal diseases. For instance, most vitamins showed an inverse relationship with the risk of colorectal carcinoma as well as other malignancies like gastric and esophageal cancer in observational trials, however interventional trials failed to prove a clear beneficial preventive role. On the other hand, more solid evidence was obtained from high quality studies for a role of certain vitamins in specific entities. Examples for this include the therapeutic role of vitamin E in patients with non-alcoholic steatohepatitis, the additive role of vitamins B12 and D to the standard therapy of chronic hepatitis C virus, the role of vitamin C in reducing the risk of gallstones, the positive outcome with vitamin B12 in patients with aphthous stomatitis, and the beneficial effect of vitamin D and B1 in patients with inflammatory bowel disease. Other potential uses are yet to be elaborated, like those on celiac disease, pancreatic cancer, pancreatitis, cholestasis and other potential fields. Data from several ongoing interventional trials are expected to add to the current knowledge over the coming few years. Given that vitamin supplementation is psychologically accepted by patients as a natural compound with relative safety and low cost, their use should be encouraged in the fields where positive data are available.

Physical activity behavior and role overload in mothers.

PubMed

Lovell, Geoff P; Butler, Frances R

2015-01-01

We examined physical activity stages of change, physical activity behavior, and role overload in different stages of motherhood in a predominantly Australian sample. Neither physical activity behavior, stages of physical activity change, nor role overload significantly differed across motherhood groups. Role overload was significantly higher for mothers in the contemplation, planning, and action stages of physical activity than in the maintenance stage of change. Role overload had a weak, although significant, negative correlation with leisure-time physical activity. We conclude that strategies focused upon reducing role overload or perceived role overload have only limited potential to meaningfully increase leisure-time physical activity in mothers.

Ethics of caring and professional roles.

PubMed

Paulsen, Jens Erik

2011-03-01

Normative discussions about modern health care often revolve around principles stating what must not be done or how to ration scarce resources in the name of justice. These are important discussions. However, in order to have an impact on clinical roles, ethical reflection must be able to describe and address the complexities and challenges of modern nursing and doctoring, and maybe even the patient role. A multi-principled approach, such as the one suggested by Beauchamp and Childress, can obviously address almost any such issue, but a great deal of translation is often required in order to address role-related issues. I shall here argue that an ethics of caring is better suited to grasping the big picture when the question is how to create value-informed clinical roles in an era of rapid development.

Marital role attitudes and expected role behaviors of college youth in mainland China and Taiwan.

PubMed

Hsieh, K H; Burgess, R L

1994-09-01

Mainland China and Taiwan have been politically and physically segregated since 1949, and it was not until the late 1980s that limited contacts and cultural exchanges between the two societies began to take place. During their period of segregation, the two societies adopted different approaches toward gender roles. While gender equality was actively promoted in mainland China, the government in Taiwan lacked the theoretical guidance on how to achieve such equality. Gender egalitarianism in Taiwan therefore remains at the abstract or philosophical level with no specification of what gender equality means in concrete terms. Testing the hypothesis that people in mainland China have become more egalitarian than have people in Taiwan with respect to the division of marital roles, the authors investigated the differences in marital role attitudes and expected behavior among selected college students in mainland China and Taiwan. Survey responses were obtained from 185 male and 154 female students from Taiwan and 150 male and 138 female students from mainland China of different years and majors on four dimensions of marital role attitudes and six areas of traditional husband and wife role behaviors. The dimensions were determined through exploratory and confirmatory factor analyses. The data indicate that although most of the hypothesized societal differences are supported, some are not. The authors speculate that possible regressive changes in mainland China and progressive changes in Taiwan during the past decade were responsible for the discrepancy between hypotheses and results.

Clinical skills are an important and necessary part of clinical competence. Simulation plays an important role in many fields of medical education. Although role-playing is common in communication training, there are no reports about the use of student role-plays in the training of technical clinical skills. This article describes an educational intervention with analysis of pre- and post-intervention self-selected student survey evaluations. After one term of skills training, a thorough evaluation showed that the skills-lab training did not seem very realistic nor was it very demanding for trainees. To create a more realistic training situation and to enhance students' involvement, case studies and role-plays with defined roles for students (i.e. intern, senior consultant) were introduced into half of the sessions. Results of the evaluation in the second term showed that sessions with role-playing were rated significantly higher than sessions without role-playing.

2012-02-01

To examine inter-relationships among arthritis (A), work (W) and personal life (P) roles and their reciprocal influences, especially experiences of role balance/imbalance among individuals with inflammatory arthritis (IA) and OA. Eight focus groups were conducted with 24 women and 16 men (aged 29-72 years). A purposive sample was recruited from community advertising. Eligibility included current employment or having been employed within the previous year. Participants were asked about ways arthritis, work and personal life roles intersected and their impact. A standardized questionnaire collected demographic, symptom and employment data for descriptive purposes. Participants noted that having arthritis affected their identity and intersected with work and personal roles, creating role overload, role conflict, role strain and role facilitation. Role overload highlighted that arthritis both affected and was impacted by work and personal life (A → W; A → P; W → A; P → A). Role conflict focused on A → W and A → P difficulties, whereas role facilitation emphasized the positive impact of work and personal life roles on arthritis (W → A; P → A). Role strain was pervasive and arose from numerous sources. Personal strategies (e.g. positive framing) and contextual factors (e.g. support) were important in contributing to or ameliorating role balance/imbalance. By comprehensively examining multiple types of role balance/imbalance and the context within which it occurs, this study identifies gaps in patient-oriented measurement of the impact of arthritis and areas of need in the development of arthritis intervention.

[The Relationship Between Marital Adjustment and Psychological Symptoms in Women: The Mediator Roles of Coping Strategies and Gender Role Attitudes].

2015-01-01

The aim of this study were to investigate the mediator role of coping strategies and gender roles attitudes on the relationship between women's marital adjustment and psychological symptoms. 248 married women participated in the study. Participants completed Marital Adjustment Scale, Ways of Coping Questionnaire, Brief Symptom Inventory, Gender Role Attitudes Scale and Demographic Information Form. Regression analyses revealed that Submissive (Sobel z= -2.47, p<.01) and Helpless Coping Approach (Sobel z=-2.95, p<.001) have partial mediator role on the relationship between marital relationship score and psychological symptom level. Also, having Egalitarian Gender Role Attitude effects the psychological symptoms in relation with the marital relationship, but it is seen that this effect is not higher enough to play a mediator role (Sobel z =-1.21, p>.05). Regression analysis showed that there is a statistically significant correlation between women's marital adjustment and their psychological symptoms, indicating that the marital adjustment decreases as the psychological symptoms increases. It is also found out that submissive and helpless coping approach have mediator roles in this relationship. Also, contrary to expectations, having egalitarian gender role attitude effects the psychological symptoms in relation with the marital relationship, but this effect does not seem to play a mediator role. It is thought that the effects of marriage and couple therapy approaches considering couples’s problem solving and coping styles should be examined in further studies.

Exploring emergency nurse practitioners' perceptions of their role.

PubMed

Bagley, Sue

2018-02-21

Since the 1980s, the emergency nurse practitioner (ENP) role has evolved as increasing socioeconomic pressures and changing government policy have led to new working practices in emergency departments. Similarly, a lack of consensus regarding educational support for ENPs and the regulation of ENP training, mean that variations remain in the scope of practice, role description and academic requirements for ENPs. To explore ENPs' perceptions of their changing role, including their educational requirements and whether their training needs are being met. This qualitative phenomenological study examined the views of six ENPs using semi-structured interviews. The study identified four themes: inadequate protected time for continuing professional development (CPD); importance of senior medical support in role expansion and CPD; inconsistent educational preparation for expanded roles; and the ENPs' perceived reasons for role expansion. Although all the participants stated that it was challenging to find time for CPD when working in busy clinical environments, this was regarded as less important than the positive effect of senior medical support for advanced roles. Over the past three decades, the ENP role has become well established, which has led to increased confidence, and the development of collaborative ways of working, among ENPs and their colleagues. However, while ENPs have embraced the challenges of their changing role, educational support has not been consistent. There are still disparities in ENPs' scope of practice, expectations of the role between services, and the educational preparation required to undertake the role. ©2018 RCN Publishing Company Ltd.

Effects of children on parental sex-role orientation.

PubMed

Ganong, L H; Coleman, M

1987-09-01

The predominant theories of gender-role development have focused primarily on childhood; socialization processes for gender roles are explained from birth through adolescence. The assumption appears to be that gender roles are developed in childhood and implemented, basically unchanged, in adulthood. There is evidence, however, that gender-role self-perceptions change in adulthood. This study investigates the effects of sex of children on parental sex-role orientation. More specifically, an attempt is made to determine if the presence of sons affects sex-role self-concept of parents more than the presence of daughters. The Bem Sex Role Inventory was administered to 153 parental dyads who had daughters only (n=41), sons only (n=41), or an equal number of both sons and daughters (n=71). Sex of child, especially sons, did appear to have an effect on parents' femininity. Fathers with sons have lower femininity scores than fathers with daughters only, and mothers with sons have higher femininity scores than mothers with daughters only.

An important question in the study of language production is the nature of the semantic information that speakers use to create syntactic structures. A common answer to this question assumes that thematic roles help to mediate the mapping from messages to syntax. However, research using structural priming has suggested that the construction of syntactic frames may be insensitive to variations in thematic roles within messages (Cognition 35 (1990) 1; Psychological Review 99 (1992) 150). Because these studies involved structural alternations whose syntax covaries with the order of thematic roles, it is difficult to assess any independent contribution that role information may make to the positioning of phrases. In this study, we primed the order of the roles without changing the syntactic structure of the sentences produced, and found that the order of the roles was influenced by the priming manipulation. This implies that thematic roles or the features that differentiate them are active within the mapping between messages and sentence structures.

Objective. To examine inter-relationships among arthritis (A), work (W) and personal life (P) roles and their reciprocal influences, especially experiences of role balance/imbalance among individuals with inflammatory arthritis (IA) and OA. Methods. Eight focus groups were conducted with 24 women and 16 men (aged 29–72 years). A purposive sample was recruited from community advertising. Eligibility included current employment or having been employed within the previous year. Participants were asked about ways arthritis, work and personal life roles intersected and their impact. A standardized questionnaire collected demographic, symptom and employment data for descriptive purposes. Results. Participants noted that having arthritis affected their identity and intersected with work and personal roles, creating role overload, role conflict, role strain and role facilitation. Role overload highlighted that arthritis both affected and was impacted by work and personal life (A → W; A → P; W → A; P → A). Role conflict focused on A → W and A → P difficulties, whereas role facilitation emphasized the positive impact of work and personal life roles on arthritis (W → A; P → A). Role strain was pervasive and arose from numerous sources. Personal strategies (e.g. positive framing) and contextual factors (e.g. support) were important in contributing to or ameliorating role balance/imbalance. Conclusions. By comprehensively examining multiple types of role balance/imbalance and the context within which it occurs, this study identifies gaps in patient-oriented measurement of the impact of arthritis and areas of need in the development of arthritis intervention.

Background: "Adolescent pregnancy is one of the most pressing, persistent, and poignant problems facing society" (Yoos, 1987, p. 247). Manitoba's teen pregnancy rates are among the highest in Canada. Yet, little is known about adolescent fathers and their parenting involvement. The purpose of this descriptive correlational study was to explore variables which may influence teen fathers' participation in parenting.Methods: A convenience sample of 30 adolescent fathers, whose partners were attending an Adolescent Prenatal Clinic, completed two questionnaires: Offer Self-Image-Revised, and Perceived Parenting Role Performance. Guided by family role theory, four hypotheses were examined utilizing a quantitative research method.Results: Data analysis revealed that 30% of these respondents had a low to very low self-image. Pearson's correlation coefficient, which facilitated hypotheses testing, failed to validate a relationship between teen fathers' perceived role performance and self-image, and perceived parenting role expectations. Nevertheless, a moderate negative correlation was noted between teen fathers' self-image and their perceived parenting role expectations (r = -.35, p <.05).Conclusions: These findings contradict the philosophy of family role theory. Results of this study indicated that teen fathers want to be involved in parenting. However, unrealistic expectations and the inability to combine the developmental tasks of adolescence with the responsibilities of fatherhood increase their vulnerability to parenting failure.

Toward edge minability for role mining in bipartite networks

2016-11-01

Bipartite network models have been extensively used in information security to automatically generate role-based access control (RBAC) from dataset. This process is called role mining. However, not all the topologies of bipartite networks are suitable for role mining; some edges may even reduce the quality of role mining. This causes unnecessary time consumption as role mining is NP-hard. Therefore, to promote the quality of role mining results, the capability that an edge composes roles with other edges, called the minability of edge, needs to be identified. We tackle the problem from an angle of edge importance in complex networks; that is an edge easily covered by roles is considered to be more important. Based on this idea, the k-shell decomposition of complex networks is extended to reveal the different minability of edges. By this way, a bipartite network can be quickly purified by excluding the low-minability edges from role mining, and thus the quality of role mining can be effectively improved. Extensive experiments via the real-world datasets are conducted to confirm the above claims.

An Attitude Strength and Self-Perception Framework Regarding the Bi-directional Relationship of Job Satisfaction with Extra-Role and In-Role Behavior: The Doubly Moderating Role of Work Centrality

PubMed Central

Ziegler, Rene; Schlett, Christian

2016-01-01

Studies have identified variables either moderating the extent to which job satisfaction predicts work behavior or moderating the reverse impact of work behavior on job satisfaction. Based on an attitude strength and self-perception framework, we argue that certain variables may moderate both the predictive utility of job satisfaction for work behavior and the impact of work behavior on job satisfaction. Specifically focusing on work centrality, we hold that high work centrality renders job satisfaction a strong job attitude, whereas low work centrality renders job satisfaction a weak job attitude. Hence, the predictive utility of job satisfaction for both extra-role behavior and in-role behavior should be higher the more work is central to employees. In contrast, the influence of extra-role behavior, but not of in-role behavior, on job satisfaction should be higher the less work is central to employees. Results of a two-wave study (N = 176) were in line with these predictions. We discuss further variables that may play a similar role for the bi-directional relationship between job satisfaction and work behavior. PMID:26973556

The effectiveness of social impact assessment (SIA) hinges largely on the capabilities and ethics of the practitioners, yet few studies have dedicated to discuss the expectations for these professionals. Recognising this knowledge gap, we employed the systemic review approach to construct a framework of roles of SIA practitioners from literature. Our conceptual framework encompasses eleven roles, namely project manager of SIA, practitioner of SIA methodologies, social researcher, social strategy developer, social impact management consultant, community developer, visionary, public involvement specialist, coordinator, SIA researcher, and educator. Although these roles have been stratified into three overarching categories, the project, community and SIAmore » development, they are indeed interrelated and should be examined together. The significance of this study is threefold. First, it pioneers the study of the roles of SIA practitioners in a focused and systematic manner. Second, it informs practitioners of the expectations of them thereby fostering professionalism. Third, it prepares the public for SIAs by elucidating the functions and values of the assessment. - Highlights: • We adopt systematic review to construct a framework of roles of social impact assessment (SIA) practitioners from literature. • We use three overarching categorises to stratify the eleven roles we proposed. • This work is a novel attempt to study the work as a SIA practitioner and build a foundation for further exploration. • The framework informs practitioners of the expectations on them thus reinforcing professionalism. • The framework also prepares the public for SIAs by elucidating the functions and values of the assessment.« less

Developing the role of the healthcare assistant.

PubMed

Hancock, H; Campbell, S

Two studies are described in this article. The first evaluated the preparedness of healthcare assistants (HCAs) to develop a new role and attend an HCA development programme. The second examined the impact of one NHS trust's HCA development programme on the role of the HCA, on other members of the multidisciplinary team and on patients. The research methodology was qualitative and inductive, using a naturalistic approach in both studies, and a 360 degree model of assessment and feedback in study two. For both studies, the data were analysed following the principles of thematic analysis. Findings Eight out of 12 HCAs in study one were prepared to attend the programme and to develop their role. Study two indicated a positive but restricted impact of the HCA development programme on the HCAs' role, that of other healthcare professionals and on patient care. The findings have implications for role development in the NHS and for the development of programmes that aim to address these changes. The HCA development programme has been reviewed and extended, and strategies to promote and support role development in the clinical setting have been introduced in the trust where the research was conducted.

Unusually dynamic sex roles in a fish.

Forsgren, Elisabet; Amundsen, Trond; Borg, Asa A; Bjelvenmark, Jens

2004-06-03

Sex roles are typically thought of as being fixed for a given species. In most animals males compete for females, whereas the females are more reluctant to mate. Therefore sexual selection usually acts most strongly on males. This is explained by males having a higher potential reproductive rate than females, leading to more males being sexually active (a male-biased operational sex ratio). However, what determines sex roles and the strength of sexual selection is a controversial and much debated question. In this large-scale field study, we show a striking temporal plasticity in the mating competition of a fish (two-spotted goby, Gobiusculus flavescens). Over the short breeding season fierce male-male competition and intensive courtship behaviour in males were replaced by female-female competition and actively courting females. Hence, sex role reversal occurred rapidly. This is the first time that a shift in sex roles has been shown in a vertebrate. The shift might be explained by a large decline in male abundance, strongly skewing the sex ratio towards females. Notably, the sex role reversal did not occur at an equal operational sex ratio, contrary to established sex role theory.

Distinguishing the Clinical Nurse Specialist From Other Graduate Nursing Roles.

PubMed

Mohr, Lynn D; Coke, Lola A

Today's healthcare environment poses diverse and complex patient care challenges and requires a highly qualified and experienced nursing workforce. To mitigate these challenges are graduate nursing roles, each with a different set of competencies and expertise. With the availability of many different graduate nursing roles, both patients and healthcare professionals can be confused in understanding the benefit of each role. To gain the maximum benefit from each role, it is important that healthcare providers and administrators are able to distinguish the uniqueness of each role to best use the role and develop strategies for effective collaboration and interprofessional interaction. The purpose of this article was to define the role, educational preparation, role differences, and practice competencies for the clinical nurse specialist (CNS), nurse practitioner, clinical nurse leader, and nurse educator/staff development educator roles. A second purpose was to provide role clarity and demonstrate the unique value the CNS brings to the healthcare environment. Using evidence and reviewing role competencies established by varying organizations, each role is presented with similarities and differences among the roles discussed. In addition, collaboration among the identified roles was reviewed, and recommendations were provided for the new and practicing CNSs. Although there are some similarities among the graduate nursing roles such as in educational, licensing, and certification requirements, each role must be understood to gain the full role scope and benefit and glean the anticipated outcomes. Healthcare providers must be aware of the differences in graduate nursing roles, especially in comparing the CNS with other roles to avoid confusion that may lead to roles being underused with a limited job scope. The CNS provides a unique set of services at all system outcome levels and is an essential part of the healthcare team especially in the acute care setting.

Researchers' Roles in Patient Safety Improvement.

2016-03-01

In this article, we explore how researchers can contribute to patient safety improvement. We aim to expand the instrumental role researchers have often occupied in relation to patient safety improvement. We reflect on our own improvement model and experiences as patient safety researchers in an ongoing Finnish multi-actor innovation project through self-reflective narration. Our own patient safety improvement model can be described as systemic. Based on the purpose of the innovation project, our improvement model, and the improvement models of the other actors in the project, we have carried out a wide range of activities. Our activities can be summarized in 8 overlapping patient safety improvement roles: modeler, influencer, supplier, producer, ideator, reflector, facilitator, and negotiator. When working side by side with "practice," researchers are offered and engage in several different activities. The way researchers contribute to patient safety improvement and balance between different roles depends on the purpose of the study, as well as on the underlying patient safety improvement models. Different patient safety research paradigms seem to emphasize different improvement roles, and thus, they also face different challenges. Open reflection on the underlying improvement models and roles can help researchers with different backgrounds-as well as other actors involved in patient safety improvement-in structuring their work and collaborating productively.

Postgraduate internal medicine residents' roles at patient discharge - do their perceived roles and perceptions by other health care providers correlate?

Card, Sharon Elizabeth; Ward, Heather A; Chipperfield, Dylan; Sheppard, M Suzanne

2014-01-01

Knowing one's own role is a key collaboration competency for postgraduate trainees in the Canadian competency framework (CanMEDS®). To explore methods to teach collaborative competency to internal medicine postgraduate trainees, baseline role knowledge of the trainees was explored. The perceptions of roles (self and others) at patient discharge from an acute care internal medicine teaching unit amongst 69 participants, 34 physicians (25 internal medicine postgraduate trainees and 9 faculty physicians) and 35 health care professionals from different professions were assessed using an adapted previously validated survey (Jenkins et al., 2001). Internal medicine postgraduate trainees agreed on 8/13 (62%) discharge roles, but for 5/13 (38%), there was a substantial disagreement. Other professions had similar lack of clarity about the postgraduate internal medicine residents' roles at discharge. The lack of interprofessional and intraprofessional clarity about roles needs to be explored to develop methods to enhance collaborative competence in internal medicine postgraduate trainees.

Roles for librarians in systematic reviews: a scoping review

Objective What roles do librarians and information professionals play in conducting systematic reviews? Librarians are increasingly called upon to be involved in systematic reviews, but no study has considered all the roles librarians can perform. This inventory of existing and emerging roles aids in defining librarians’ systematic reviews services. Methods For this scoping review, the authors conducted controlled vocabulary and text-word searches in the PubMed; Library, Information Science & Technology Abstracts; and CINAHL databases. We separately searched for articles published in the Journal of the European Association for Health Information and Libraries, Evidence Based Library and Information Practice, the Journal of the Canadian Heath Libraries Association, and Hypothesis. We also text-word searched Medical Library Association annual meeting poster and paper abstracts. Results We identified 18 different roles filled by librarians and other information professionals in conducting systematic reviews from 310 different articles, book chapters, and presented papers and posters. Some roles were well known such as searching, source selection, and teaching. Other less documented roles included planning, question formulation, and peer review. We summarize these different roles and provide an accompanying bibliography of references for in-depth descriptions of these roles. Conclusion Librarians play central roles in systematic review teams, including roles that go beyond searching. This scoping review should encourage librarians who are fulfilling roles that are not captured here to document their roles in journal articles and poster and paper presentations. PMID:29339933

[The role in verbal communication].

PubMed

Panini, Roberta; Fiorini, Fulvio

2015-01-01

The content of the thought is expressed by words articulated correctly according to grammar and syntax. The meanings are conveyed through words but also through the way they are used, the manner of communication. The real reason of communication is the intention, the purpose, often implicit, which determines the source of a speech. It is possible to identify a direct aim (the purpose of communicating) and an indirect objective (the role intention), understood as keeping a role between the speaker and the listener. The role is also indicated by the non-verbal or paraverbal component of the message, that is the tone of voice, the emphasis and the posture of the communicator. In the multitude of possible relationship (affective, social, business, political, religious), frequently bounded together, we can recognize three categories of relations: symmetrical, reciprocal and complementary.

The influence of role-specific self-concept and sex-role identity on career choices in science

NASA Astrophysics Data System (ADS)

Baker, Dale R.

Despite much effort on the part of educators the number of females who choose science careers remains low. This research focuses on two factors which may be influencing females in their choice of careers. These factors are role-specific self-concept in science and self perception in terms of stereotypical masculine and feminine characteristics. In addition logical ability and mathematics and science courses were also examined as factors in career choice. Females preferring science related careers and females preferring nontraditional careers such as police, military and trades were found to have a positive role-specific self-concept and a masculine perception of themselves. Females preferring traditional careers such as teacher or hairdresser had a poor role-specific self-concept and a more feminine perception of themselves. Males as a group were found to have a more positive role-specific self-concept than females. Logical ability was also related to a science career preference for both males and females. Males expected to take more higher level math courses than females, while females preferring science careers expected to take the most higher level science courses.

Association between work role stressors and sleep quality.

2018-05-17

Work-related stressors are associated with low sleep quality. However, few studies have reported an association between role stressors and sleep quality. To elucidate the association between role stressors (including role conflict and ambiguity) and sleep quality. Cross-sectional study of daytime workers whose sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Work-related stressors, including role stressors, were assessed using the Generic Job Stress Questionnaire (GJSQ). The association between sleep quality and work-related stressors was investigated by logistic regression analysis. A total of 243 participants completed questionnaires were received (response rate 71%); 86 participants reported poor sleep quality, based on a global PSQI score ≥6. Multivariable logistic regression analysis revealed that higher role ambiguity was associated with global PSQI scores ≥6, and that role conflict was significantly associated with sleep problems, including sleep disturbance and daytime dysfunction. These results suggest that high role stress is associated with low sleep quality, and that this association should be considered an important determinant of the health of workers.

Gray, Frances C; White, Ann; Brooks-Buck, Judith

2013-01-01

This is a report of the results of a pilot project conducted to identify the areas where role confusion/ambiguity exists in the practice of nurse case management. A convenience sample of 25 registered nurses practicing as case managers in a small east coast medical treatment facility's outpatient clinics. Participants responded to 2 Likert-type surveys designed to evaluate role confusion from an individual and a team membership perspective. Analysis indicated that nurse case managers experience role confusion in the specific areas of conflicts between time resources, capabilities, and multiple individual roles. There was no identified role confusion associated with membership on multidisciplinary teams. The application of the Synergy Model as a theoretical framework for nurse case management serves as a benchmark for the implementation of evidence-based practices. This project could serve as the starting point for the development of a skill set for nurse case managers, for the standardization of the practice, and for the recognition of nurse case management as a legitimate nursing subspecialty.

A Role Calculus for ORM

NASA Astrophysics Data System (ADS)

Curland, Matthew; Halpin, Terry; Stirewalt, Kurt

A conceptual schema of an information system specifies the fact structures of interest as well as related business rules that are either constraints or derivation rules. Constraints restrict the possible or permitted states or state transitions, while derivation rules enable some facts to be derived from others. Graphical languages are commonly used to specify conceptual schemas, but often need to be supplemented by more expressive textual languages to capture additional business rules, as well as conceptual queries that enable conceptual models to be queried directly. This paper describes research to provide a role calculus to underpin textual languages for Object-Role Modeling (ORM), to enable business rules and queries to be formulated in a language intelligible to business users. The role-based nature of this calculus, which exploits the attribute-free nature of ORM, appears to offer significant advantages over other proposed approaches, especially in the area of semantic stability.

Emotion-regulation ability, role stress and teachers' mental health.

PubMed

Mérida-López, S; Extremera, N; Rey, L

2017-10-01

Work-related stressors, including role ambiguity and role conflict, are related to psychological maladjustment and mental ill-health. However, to date, the role of personal resources such as emotion-regulation ability (ERA) in the prediction of mental health indicators has not been addressed. To examine whether ERA would contribute to explaining teachers' depression, anxiety and stress symptoms beyond role ambiguity and role conflict. We carried out a cross-sectional questionnaire survey. We used a correlation matrix and hierarchical regression models to analyse the data. Three hundred and thirty-six Spanish teachers (185 female) from several grade levels completed the surveys (40% response rate). Role ambiguity and role conflict were positively related to depression, anxiety and stress symptoms. ERA was negatively related to teachers' scores on depressive, anxious and stress symptoms, with predictive power above the main effects of role ambiguity and role conflict. An interaction between role ambiguity and ERA was also significant in predicting depression. Our study provides preliminary evidence suggesting the development of integrative models considering work-related stressors along with personal resources such as ERA aiming to prevent teachers' mental ill-health. Future studies should examine the influence of ERA on psychological symptoms using longitudinal designs. © The Author 2017.

Alterations in osteoblast growth, differentiation and activity play a role in the pathogenesis of several rheumatic diseases, such as rheumatoid arthritis, spondyloarthritides, osteoarthritis, and osteoporosis. In fact, in these rheumatic diseases, abnormal activity of Wnt signaling, receptor activator of nuclear factor-κB (RANK)-RANK ligand (RANKL)-osteoprotegerin (OPG) signaling, bone morphogenetic proteins (BMPs) pathway and other mechanisms have been described in osteoblasts. This review article is focused on current knowledge on the role of osteoblast dysregulation occurring in rheumatic diseases.

Gender roles and sexual behavior among young women.

PubMed

Lucke, J C

1998-08-01

The associations between gender role orientation and high-risk sex behaviors were explored in a study of 400 sexually active women 16-24 years of age (mean, 20.4 years) recruited from two metropolitan family planning clinics in Queensland, Australia. Three dimensions of gender role orientation were examined: gender role personality traits, gender role attitudes, and gender role dating behavior. It was hypothesized that women with more nontraditional or "masculine" characteristics are more likely than those with traditional or "feminine" characteristics to engage in unsafe sexual behaviors. Only partial support was found for this hypothesis. Although a number of univariate relationships emerged, very few associations between sexual behavior and gender roles remained significant in the multivariate analysis. Logistic regression analysis indicated that women with two or more sexual partners in the year preceding the study were significantly more likely than those with 0-1 sex partners to have masculine personality traits and to be more liberal in their attitudes toward women in society. Nonuse of condoms with the most recent sexual partner was not significantly associated with the gender role variables; however, women who reported masculine dating behaviors were more likely to have used a condom with their most recent nonsteady sexual partner. Similarly, substance use before or during last sexual intercourse was associated with masculine traits when the partner was nonsteady but was not related to gender role orientation when the partner was steady. The association of "masculine" personality traits with multiple partners and substance use indicates that caution should be exercised in assuming that masculine gender role characteristics are beneficial for women in sexual situations.

Managers' experience of training the associate practitioner role.

PubMed

Thurgate, Claire; MacGregor, Janet; O'Keefe, Helen

2013-03-01

This paper documents findings from a service evaluation of clinical managers' (n = 5) perceptions of the assistant practitioner (AP) training programme in one National Health Service (NHS) Trust in South East England, UK. The AP has been identified in England as a means for supporting registered nurses and enhancing patient care. The development of the AP role requires managers to consider how the role will be embedded and how they work with education providers. This service evaluation interviewed five clinical managers who have supported APs in relation to their function for the specialist clinical role. The AP role should be defined by competence, boundaries and the skill mix needed for specific clinical team function. Careful recruitment is vital and mentors need clear outcomes for the AP role. Managers need to be involved in all levels of the programme, from liaison with the Higher Education Institute and Trust decisions on role job descriptions and employment. Recruitment is vital, individuals have to be flexible and responsive to change and should be used in relation to their clinical competence. A competency framework for all health-care workers was the managers' desire for job descriptions and assessment of practice so that every member of the health-care team was 'fit for purpose'. Nurse managers need to work with workforce leads when considering introduction of new roles so appropriate skill mix is achieved and the AP role is embedded. © 2012 Blackwell Publishing Ltd.

To determine and compare the perception among nurses and doctors of the roles and tasks of critical care advanced practice nurses (APNs) in order to establish standardized and formally agreed role criteria for such critical care APNs. This study measured and analyzed the necessity of each of the roles and tasks of critical care APNs, as perceived by nurses and doctors, through a survey of 121 participants: 71 nurses in 7 intensive care units (ICUs) at a general hospital in Seoul, and 50 doctors who used ICUs. Data collection utilized a questionnaire of 128 questions in the following fields: direct practice (79), leadership and change agent (17), consultation and collaboration (15), education and counseling (11), and research (6). Both the nurses' and the doctors' groups confirmed the necessity of critical care APNs, with doctors who frequently used ICUs indicating a particularly strong need. As for the priority of each role of critical care APNs, the nurses considered direct practice to be the most critical, followed by education and counseling, research, consultation and collaboration, and leadership and change agent. The doctors also considered direct practice to be the most critical, followed by education and counseling, consultation and collaboration, research, and leadership and change agent. There was a statistically significant difference between how the two groups regarded all the roles, except for the consultation and collaboration roles. As for the necessity of each role of critical care APNs, the nurses considered research to be the most necessary, followed by education and counseling, consultation and collaboration, leadership and change agent, and direct practice. The doctors, on the other hand, considered education and counseling to be the most necessary, followed by research, consultation and collaboration, leadership and change agent, and direct practice. The responses of the two groups to all the roles, except for education and counseling roles

Do employed and nonemployed Korean mothers experience different levels of psychological well-being in relation to their gender role attitudes and role qualities?

PubMed

Kim, H

1998-06-01

This study explored the association of gender role attitudes (GRAs) and the quality of roles with the psychological well-being among employed and nonemployed mothers in Korea. Evidence supports the thesis that employed mothers with more liberal GRAs will report higher levels of psychological well-being. All role qualities were expected to be related to women's psychological well-being regardless of work status. Maternal role was expected to be more important in determining a working mothers well-being, but wife role was in fact the most important. Among nonemployed mothers, both the maternal and wife role affected well-being. Participants were recruits from a variety of institutional settings in Seoul, Korea, in 1995. The sample included 700 mothers, of whom 263 were working mothers; 295 were nonemployed mothers. Most were highly educated and affluent. The first model included only social structural variables, which were unrelated to the relationship between employment status and well-being. Gender of children was the only significant variable. Nonemployed mothers with a son had greater well-being than those without a son. The model excluding all social structural variables showed that GRA was unrelated to employed mothers' well-being. But, inclusion of the interaction between attitude and group suggests that well-being was related to agreement with whatever their role was. A model that included role qualities found that roles as wife, mother, and employee were positively related to well-being. The role of wife was significantly related to well-being among employed mothers. The wife and mother roles were significantly related to well-being among nonemployed mothers.

Health education and the teacher's role.

Charlton, A

1981-01-01

Health education is receiving increased attention in English schools. A currently favoured method of incorporating it into the curriculum is to include relevant parts of it in all subjects. Some teachers however are unwilling to include a health education topic in their teaching. This paper looks at the possibility that this unwillingness could be associated with the way in which teachers view their role and what they think is the main aim of Health Education. Questions were put to 672 future teachers in training and 160 of their tutors. The teacher's role most frequently selected by both group was "to help all pupils make the most of their talents". Students intending to teach in primary schools provided a striking exception: 53.6% of them chose "to give pupils basic skills" as their first choice. The most popular first choice for the aims o health education was "to give information". Again primary teachers differed, however, the largest percentage selecting "to influence pupils' attitudes" (38.7%) as their first choice. The future teachers who saw their main role to be giving information in their own subject favoured the teaching of health education as a separate course, whereas those who chose "contributing to a total curriculum" as their essential role mainly opted for the inclusion of health education in all subjects. Not only view on the role of a teacher, but also specialist subject and type of school appeared to be related to views on health education.

Predictors and correlates of maternal role competence and satisfaction.

PubMed

Ngai, Fei-Wan; Wai-Chi Chan, Sally; Ip, Wan-Yim

2010-01-01

Developing a sense of competence and satisfaction in the maternal role enhances positive parenting and healthy development of the child. There is limited longitudinal research on the predictive factors influencing maternal role competence and satisfaction. The aim of this study was to determine the predictive and concurrent associations of prenatal perceived maternal role competence, learned resourcefulness, social support, stress, and depression to perceived maternal role competence and satisfaction at 6 weeks postpartum. A longitudinal, descriptive design was used. A convenience sample of 184 first-time pregnant women with a singleton and uneventful pregnancy were recruited from two regional public hospitals in Hong Kong. The Parenting Sense of Competence Scale, Self-control Schedule, Medical Outcomes Study Social Support Survey, Social Readjustment Rating Scale, and Edinburgh Postnatal Depression Scale were used to assess maternal role competence and satisfaction, learned resourcefulness, social support, stress, and depressive symptoms, respectively. Data were collected during pregnancy and at 6 weeks postpartum. Multiple regression analysis showed that perceived maternal role competence and satisfaction at 6 weeks postpartum were predicted by prenatal perceived maternal role competence and learned resourcefulness and were associated with postnatal learned resourcefulness and depression. Social support and stress were not associated directly with perceived maternal role competence and satisfaction at 6 weeks postpartum. The present findings suggest that maternal learned resourcefulness and depression are important factors affecting perceived maternal role competence and satisfaction at postpartum. Culturally competent healthcare should be developed to promote the psychological well-being of women and to equip women with the learned resourcefulness skills to facilitate maternal role taking and enhance women's sense of competence and satisfaction in the maternal

The role of WOX genes in flower development

PubMed Central

Costanzo, Enrico; Trehin, Christophe; Vandenbussche, Michiel

2014-01-01

Background WOX (Wuschel-like homeobOX) genes form a family of plant-specific HOMEODOMAIN transcription factors, the members of which play important developmental roles in a diverse range of processes. WOX genes were first identified as determining cell fate during embryo development, as well as playing important roles in maintaining stem cell niches in the plant. In recent years, new roles have been identified in plant architecture and organ development, particularly at the flower level. Scope In this review, the role of WOX genes in flower development and flower architecture is highlighted, as evidenced from data obtained in the last few years. The roles played by WOX genes in different species and different flower organs are compared, and differential functional recruitment of WOX genes during flower evolution is considered. Conclusions This review compares available data concerning the role of WOX genes in flower and organ architecture among different species of angiosperms, including representatives of monocots and eudicots (rosids and asterids). These comparative data highlight the usefulness of the WOX gene family for evo–devo studies of floral development. PMID:24973416

Intimate partner violence in Kenya: expanding healthcare roles.

PubMed

Maina, Geoffrey; Majeke, Sisana

To identify health professionals' perceptions of their role working in the emergency department (ED) in managing and preventing intimate partner violence in Kenya. A qualitative research study was conducted involving in-depth interviews with one doctor, six nurses and four clinical officers who had worked in an ED for at least one year. Interviews were recorded on a digital voice recorder. Transcription and subsequent analysis of the interviews were done using NVivo 7 software for qualitative data. Emerging ideas were collated into themes and sub-themes. Participants found themselves assuming diverse roles within and without the health setting, for example that of clinician, liaison officer, counsellor and health and community educators. These roles represented the wide scope of involvement of healthcare professionals in relation to intimate partner violence and were perceived as enhancing effectiveness in addressing domestic violence towards women. Healthcare providers identified several roles that they assume to assist abused women. These roles were considered over and above the usual clinical roles that they are expected to perform.

Sex, gender role orientation, gender role attitudes and suicidal thoughts in three generations. A general population study.

PubMed

Hunt, Kate; Sweeting, Helen; Keoghan, Margaret; Platt, Stephen

2006-08-01

Suicide and other suicidal behaviours are markedly (though differently) patterned by gender. The increase in young male suicide rates in many countries has heightened interest in whether suicidal behaviours and ideation (thoughts) are related to masculinity. Relatively little research has explored the relationship between gender role attitudes and orientation and suicidal behaviours and ideation. Most research in this area has been conducted with young people. We investigated whether gender role orientation (masculinity and femininity scores) and gender role attitudes were related to the reporting of serious suicidal thoughts in three generations (early adulthood, and early and late middle age) in a community sample. Subjects (653 men and women aged around 23 years, 754 aged around 43 years, 722 aged around 63 years) completed home interviews with nurses as part of an ongoing longitudinal community-based study of social factors and health. These included measures of suicidal ideation (thoughts), attitudes to traditional gender roles, and a validated measure of gender role orientation (masculinity and femininity scores). The prevalence of serious suicidal thoughts was higher in early adulthood (10% men, 15% women) than in early (4% men, 8% women) and late (6% men, 5% women) middle age. In early adulthood only sex was significantly related to suicidal thoughts, with women at higher risk (adjusted OR 1.74, 95% CI 1.01-3.00). In early middle age masculinity scores were negatively related to suicidal thoughts (adjusted OR for each unit increase in score 0.65: 95% CI 0.46-0.93), and more traditional views on gender roles were positively associated with suicidal thoughts (adjusted OR 1.48: 95% CI 1.07-2.04). In late middle age trends were in the same direction as in early middle age, but were not statistically significant. Femininity scores were unrelated to serious suicidal thoughts at any age. The high rates of suicidal thoughts amongst men and women in early adulthood

Little is known about the independent associations of reward and stress within specific roles with multiple measures of mental health in an ethnically diverse community sample of midlife women. The objective of this study is to examine if (1) role reward (within each role and across roles) contributes directly to mental health and buffers the negative impact of role stress and (2) associations among role occupancy, role stress, and role reward and mental health vary by race/ethnicity. With separate logistic regression analysis, we investigated cross-sectional relationships between role stress and role reward with presence/absence of high depressive symptoms (Center for Epidemiologic Studies Depression Scale [CES-D≥16]), anxiety symptoms (feeling tense or nervous, irritable or grouchy, fearful for no reason, and heart pounding or racing total score≥4), or low social functioning (bottom 25th percentile of the Short-Form-36 [SF-36] social functioning subscale) in 2549 women participating in the third visit of the Study of Women's Health Across the Nation (SWAN), a longitudinal population-based study of menopause. High reward across roles attenuated the negative impact of role stress on social functioning but not on anxiety or depression. High reward marriage buffered the impact of marital stress on depression, and high reward mothering buffered the effect of maternal stress on depression and social functioning. Compared to Caucasians, Hispanics and Chinese with high stress across roles had better social functioning, and African American mothers had lower odds of high depressive symptoms. Role reward buffers the negative impact of stress on social functioning and depression, but not on anxiety. Minorities may respond to role stress by seeking social support.

Effects of work-family-school role conflicts and role-related social support on burnout in Registered Nurses: a structural equation modelling approach.

PubMed

Goong, Hwasoo; Xu, Lijuan; Li, Chun-Yu

2016-11-01

To examine the effects of work-family-school role conflicts and role-related social support (RRSS) on burnout of nurses pursuing an advanced degree. A predictive correlational cross-sectional study design was used. Nurses were found to be a high-risk group for burnout, even more so among nurses pursuing an advanced degree. When nurses with a professional career marry and decide to become students, inter-role conflicts and burnout are possible outcomes of the resulting multiple roles. Using convenience sampling, data were collected from October 2011-May 2012. A questionnaire about work-family-school role conflicts, RRSS, burnout and general information was completed by 286 nurses pursuing an advanced degree at 12 hospitals in Korea. Data were analysed using SPSS and structural equation modelling with the Analysis of Moment Structures program. The proposed model provided a good fit to the obtained data. Work-family-school role conflicts and social support exerted significant effects on burnout. Role-related social support was found to play a partial mediating role between work-family-school role conflicts and burnout. The findings of this study imply that RRSS significantly directly and indirectly influences burnout among the nurses pursuing an advanced degree. It is necessary for nursing managers to consider implementing family- and school-friendly policies (e.g. flexible work schedules) to help nurses to manage their multiple roles and thereby decrease their burnout rate. © 2016 John Wiley & Sons Ltd.

1985-06-01

Responses from four separate samples of accountants and hospital employees provided a constructive replication of the Bedeian and Armenakis (1981) model of the causal nexus between role stress and selected outcome variables. We investigated the relationship between both role ambiguity and role conflict--as specific forms of role stress--and job-related tension, job satisfaction, and propensity to leave, using LISREL IV, a technique capable of providing statistical data for a hypothesized population model, as well as for specific causal paths. Results, which support the Bedeian and Armenakis model, are discussed in light of previous research.

Understanding doctors' ethical challenges as role virtue conflicts.

McDougall, Rosalind

2013-01-01

This paper argues that doctors' ethical challenges can be usefully conceptualised as role virtue conflicts. The hospital environment requires doctors to be simultaneously good doctors, good team members, good learners and good employees. I articulate a possible set of role virtues for each of these four roles, as a basis for a virtue ethics approach to analysing doctors' ethical challenges. Using one junior doctor's story, I argue that understanding doctors' ethical challenges as role virtue conflicts enables recognition of important moral considerations that are overlooked by other approaches to ethical analysis. © 2011 Blackwell Publishing Ltd.

1995-01-01

The author's purpose in conducting this study was to identify the relationship of sex role orientation to indices of psychological well-being among 148 American Indian working women from the Midwest. Analyses revealed that the sex-typed group had significantly higher depression scores, higher role conflict scores, lower self-esteem scores and lower life satisfaction scores when compared with the cross-typed and androgynous groups. The undifferentiated group had significantly lower self-esteem scores when compared with the androgynous group. Further research is needed to understand how different sex role orientations support different roles that American Indian women occupy.

Emerging roles of basophils in allergic inflammation.

PubMed

Miyake, Kensuke; Karasuyama, Hajime

2017-07-01

Basophils have long been neglected in immunological studies because they were regarded as only minor relatives of mast cells. However, recent advances in analytical tools for basophils have clarified the non-redundant roles of basophils in allergic inflammation. Basophils play crucial roles in both IgE-dependent and -independent allergic inflammation, through their migration to the site of inflammation and secretion of various mediators, including cytokines, chemokines, and proteases. Basophils are known to produce large amounts of IL-4 in response to various stimuli. Basophil-derived IL-4 has recently been shown to play versatile roles in allergic inflammation by acting on various cell types, including macrophages, innate lymphoid cells, fibroblasts, and endothelial cells. Basophil-derived serine proteases are also crucial for the aggravation of allergic inflammation. Moreover, recent reports suggest the roles of basophils in modulating adaptive immune responses, particularly in the induction of Th2 differentiation and enhancement of humoral memory responses. In this review, we will discuss recent advances in understanding the roles of basophils in allergic inflammation. Copyright © 2017 Japanese Society of Allergology.

Fish Peroxiredoxins and Their Role in Immunity

PubMed Central

Valero, Yulema; Martínez-Morcillo, Francisco J.; Esteban, M. Ángeles; Chaves-Pozo, Elena; Cuesta, Alberto

2015-01-01

Peroxiredoxins (Prxs) are a family of antioxidant enzymes that protect cells from oxidative damage. In addition, Prxs may act as modulators of inflammation, protect against cell death and tumour progression, and facilitate tissue repair after damage. The most studied roles of Prx1 and Prx2 are immunological. Here we present a review on the effects of some immunostimulant treatments and bacterial, viral, or parasitic infections on the expression of fish Prxs at the gene and/or protein level, and point to their important role in immunity. The Prxs show antioxidant activity as well as a protective effect against infection. Some preliminary data are presented about the role of fish Prx1 and Prx2 in virus resistance although further studies are needed before the role of fish Prx in immunity can be definitively defined.

2012-01-01

This study investigates how future informatics applications can support and challenge intensive care nurses (ICU nurses) to grow and learn continuously. To this end a research-and-design tool is introduced which is based on a model of the nursing process that starts from the idea that a nurse fulfills three different roles: the role of practitioner (using information immediately to base actions upon), the role of scholar (using information later on to learn from) and the role of human (coping with stress and dealing with emotions). In this paper the focus is on the scholar role. Twenty-eight intensive care staff members from six different hospitals were asked to recount an imposing experience from the perspective of each role. Regarding the scholar role, the participants mentioned 77 learning strategies they adopt for individual as well as organizational learning. Individual learning concerned reflection on former patient cases, reflection on current patient cases to anticipate a change in the patient's condition and reflection on personal behavior and decisions. Organizational learning concerned reflection on former patient cases. Examples of specific strategies were formal team evaluations focused on procedure and understanding the perspective of team members, being present at autopsies, and giving feedback on the nursing skills of colleagues. Based on these strategies design implications are defined for future nursing informatics applications, which will be presented.

Abstract Background Little is known about the independent associations of reward and stress within specific roles with multiple measures of mental health in an ethnically diverse community sample of midlife women. The objective of this study is to examine if (1) role reward (within each role and across roles) contributes directly to mental health and buffers the negative impact of role stress and (2) associations among role occupancy, role stress, and role reward and mental health vary by race/ethnicity. Methods With separate logistic regression analysis, we investigated cross-sectional relationships between role stress and role reward with presence/absence of high depressive symptoms (Center for Epidemiologic Studies Depression Scale [CES-D≥16]), anxiety symptoms (feeling tense or nervous, irritable or grouchy, fearful for no reason, and heart pounding or racing total score≥4), or low social functioning (bottom 25th percentile of the Short-Form-36 [SF-36] social functioning subscale) in 2549 women participating in the third visit of the Study of Women's Health Across the Nation (SWAN), a longitudinal population-based study of menopause. Results High reward across roles attenuated the negative impact of role stress on social functioning but not on anxiety or depression. High reward marriage buffered the impact of marital stress on depression, and high reward mothering buffered the effect of maternal stress on depression and social functioning. Compared to Caucasians, Hispanics and Chinese with high stress across roles had better social functioning, and African American mothers had lower odds of high depressive symptoms. Conclusions Role reward buffers the negative impact of stress on social functioning and depression, but not on anxiety. Minorities may respond to role stress by seeking social support. PMID:22360697

The clinical role of lecturers in nursing in Ireland: perceptions from key stakeholder groups in nurse education on the role.

The clinical role of lecturers in nursing has been a focus of debate since the integration of nurse education into higher education institutions. The purpose of this paper is to report the findings from the preliminary phase of a study, undertaken to investigate the perceptions of key stakeholder groups in nurse education, regarding the current clinical role of nurse lecturers in Ireland. A descriptive exploratory design was used involving focus group and individual interviews, soliciting views of purposefully selected educationalists, clinicians, policy formulators and students. The issue was examined from a policy perspective, aiming to collectively represent views of all participant groups. This approach facilitated a more complete picture of perceptions of the role to emerge, to better inform future decision making. Twenty two focus group interviews and twenty one individual interviews were conducted. Content analysis was used to identify themes. All groups were in agreement that role definition was urgently required to dispel ambiguities surrounding what the clinical role should involve. Conflicting views were evident among groups regarding lecturers' clinical credibility, visibility and teaching effectiveness. Findings highlight the essential nature of nurse lecturers engaging with clinical areas to maintain their skills, demonstrate a value for the practice component of the role and provide a link between education and practice.

Gender role biases on Indian television.

PubMed

Behera, S K

1989-01-01

Gender role biases in Indian television have served to reinforce and even enhance the degradation of women in the broader society. A content analysis of 20 news programs, 20 fictionalized serials, and 100 commercials conducted over a 3-week period in 1988 indicated that women are portrayed as victims, caretakers, and sex objects while men are presented as masters, doers, and intellectuals. Of the 400 hours of news programs studied, men newsmakers accounted for 71% of the content while women were featured in only 10% of the segments. Even then, women's portrayal in the news tended to center on their roles as beneficiaries of welfare schemes, victims of accidents, or as the wives of male dignitaries. Fictionalized dramas reinforced the sex role stereotypes of men as decisive, assertive, dominant, and career- oriented, and of women as emotionally dependent, eager to please, sentimental, and primarily concerned with family relationships. Female characters in these series were most often housewives, secretaries, teachers, or nurses. Women were featured more often (56% of content) than men in Indian commercials, yet were shown performing stereotyped female activities such as shopping, preparing meals, and dressing to obtain the sexual approval of men. This sex role stereotyping in the media is seriously impeding the struggles of women in India to achieve economic and political autonomy. To promote more positive role modeling and change women's self-image, Indian television must move immediately to portray women achieving self-realization through their careers and social participation and to depict cooperation between men and women in performing household chores.

Cardiovascular reactivity in a simulated job interview: the role of gender role self-concept.

Sieverding, Monika; Weidner, Gerdi; von Volkmann, Bettina

2005-01-01

This study investigated the relation of gender role self-concept (G-SC) to cardiovascular and emotional reactions to an ecologically relevant stressor in a sample of graduating male and female university students. Thirty-seven men and 37 women completed the Personal Attribute Questionnaire and worked on four tasks designed to reflect common features of a job interview. Blood pressure and heart rate were measured at baseline, during, and after each task; subjective stress was measured at baseline and after each task. Subjective and objective stress scores were averaged across tasks and analyzed by sex and G-SC (i.e., instrumentality, expressiveness). Results indicated that women as a group demonstrated greater emotional reactivity, but did not differ in their physiological reactions when compared to men. Regardless of sex, participants' instrumentality scores contributed significantly to the variation in subjective stress response: those scoring high on instrumentality reported less stress, but evidenced greater blood pressure reactivity than those scoring low on instrumentality. These results suggest that gender roles, particularly an instrumental self-concept, may play an important role in both subjective and objective reactions to an ecologically relevant stressor.

The assistant practitioner role in healthcare.

Dix, Ann

The assistant practitioner role is intended to free up nurses to make better use of their professional skills and improve patient outcomes. However, it can be perceived as a threat to nurses because it involves handing over clinical aspects of their work to unregistered and unregulated support workers. This article looks at how the role is developing, and the implications for nursing and quality of patient care.

Hence, the process of maternal role among working women has been investigated in this study. The grounded theory approach is used in this qualitative research. In-depth and unstructured interviews were the main way in collecting the data. Initially, the targeted sampling was started and continued gradually to the data saturation, in the form of theoretical sampling based on the obtained classes. The data was analyzed using Strauss and Corbin analysis. Accuracy and validity by four criteria in this study included: Credibility, dependability, Confirmable potential, Transferability or Fittingness. Data analysis led to the identification of the core variable of role conflict. The main classes of occupied mothers' experiences included: different pregnancy experience, returning concerns, supportive umbrella, role assignation, role overlap, role strain, gradual acceptance, satisfaction and erosion. The acceptance of numerous roles such as maternal and marital roles by working women creates various role expectations of them from their children, spouses, family and the society which in turn forces them to meet both family and job requirements and expectations; This causes role conflict in working mothers and endure a lot of pressure and stress, that can influences of mental and physical health of the mothers.

Sex role ideology among physicians.

PubMed Central

Leichner, P.; Harper, D.

1982-01-01

Physicians have been accused by some feminist writers of having traditional views on sex roles that make them part of society's oppressive power structure and therefore responsible in part for the high incidence of psychologic problems and drug dependency among women. To assess whether physicians' attitudes towards women are indeed polarized in a traditional fashion, a sex role ideology questionnaire was given to all practising physicians belonging to the Manitoba Medical Association. Overall the physicians were found to be more feminist than male college students and a group of women with traditional beliefs. Psychiatrists, who had the highest adjusted group mean score on a sex role ideology scale (high indicating feminist beliefs), were found to be significantly more feminist than family practitioners, surgeons, and obstetricians and gynecologists, although not more so than internists, radiologists, pediatricians and anesthesiologists. These findings do not support the assumption that physicians have traditional views that reflect those of society. However, the significant differences between specialties emphasize the need for educating physicians and medical students in the behaviour of women. PMID:7104916

Uncovering middle managers' role in healthcare innovation implementation.

Birken, Sarah A; Lee, Shoou-Yih Daniel; Weiner, Bryan J

2012-04-03

Middle managers have received little attention in extant health services research, yet they may have a key role in healthcare innovation implementation. The gap between evidence of effective care and practice may be attributed in part to poor healthcare innovation implementation. Investigating middle managers' role in healthcare innovation implementation may reveal an opportunity for improvement. In this paper, we present a theory of middle managers' role in healthcare innovation implementation to fill the gap in the literature and to stimulate research that empirically examines middle managers' influence on innovation implementation in healthcare organizations. Extant healthcare innovation implementation research has primarily focused on the roles of physicians and top managers. Largely overlooked is the role of middle managers. We suggest that middle managers influence healthcare innovation implementation by diffusing information, synthesizing information, mediating between strategy and day-to-day activities, and selling innovation implementation. Teamwork designs have become popular in healthcare organizations. Because middle managers oversee these team initiatives, their potential to influence innovation implementation has grown. Future research should investigate middle managers' role in healthcare innovation implementation. Findings may aid top managers in leveraging middle managers' influence to improve the effectiveness of healthcare innovation implementation.

Cooperative learning (CL) and role play are both efficient educational tools for enhancing Chinese student active learning and communication skills. This study was designed to obtain student feedback on the format of CL together with role play in the study of pharmacology in Chinese pharmaceutical undergraduates. CL was used in the self-study of new drugs used clinically but neglected in textbook and class teaching, so that groups of students were assigned to become "specialists" in one area of new drugs. Then, these "specialists" taught their new-found knowledge to other groups in role play approach involving an interaction between the pharmacist and a patient. Student perceptions of CL together with role play were examined using an eight-item survey instrument. Students were satisfied with CL together with role play. Majority of the students believed this teaching method enhanced their learning experience, made them gain more pharmacological expertise, increased the awareness of their career in future and self-educational abilities, and fostered their cooperation spirit and confidence. The materials on CL and role play were also believed pertinent. Only 63.4-76.5% and 63.1-37.3% of the students thought "CL and role-play were very funny" and "I felt very relaxed during CL together with role-play", respectively. CL together with role play is an efficient educational tool for enhancing student active-learning and communication skills. But Chinese students will take some time to adapt to this new teaching method.

Role stress amongst nurses at the workplace: concept analysis.

PubMed

Riahi, Sanaz

2011-09-01

The present study explicates the concept of role stress amongst nurses through an analysis adopted from Walker and Avant; Strategies for Theory Construction in Nursing, 4th edn, Prentice Hall, New Jersey, NY. Role stress has become a significant problem amongst nurses and has created much distress leading to burnout among many in the nursing profession. It is significant to analyse the concept of role stress and its relative attributes and consequences, in order to recognize the necessary antecedents needed to create better conditions for nurses at the workplace. A modified method developed by Walker and Avant was used for this concept analysis. A model representing the concept of role stress was developed through careful consideration of the attributes, consequences, antecedents and empirical referents of role stress. The concept analysis of role stress among nurses at the workplace recognized the vulnerability of the nursing discipline towards burnout and distress in general. It is critical to be aware of the current state of health care and note the increased workload created for nurses. Nurses are at a greater vulnerability for role stress, making it imperative for health care organizations to critically evaluate and establish preventative measures for the concept of role stress. 2011 Blackwell Publishing Ltd.

THE ROLE OF THE SPORTS PHYSICAL THERAPIST-MARATHON EVENTS

The role of the Sports physical therapist (PT) as a part of the sports medical team at marathon-type events varies widely. The PT can assume the role of an emergency medical responder (EMR) whose primary role is the management of the athlete in emergency type situations. The role of the EMR extends beyond the care of the athlete to the care and safety of the spectators. In this role, the PT must be prepared to handle any type of emergency situation, which may occur from medical conditions to acute orthopedic/sports injuries, to medical conditions which may be found in the participants of the race or the spectators. Additional roles of the PT can be in pre-race education, pre-participation screening/physicals, and other concerns by the participant related to injury prevention. Regardless of the role assumed by the PT, prior planning is essential for the safety, security, and maximal performance of the participant and to make the race enjoyable and safe for everyone.

Evolution of gender stereotypes in Spain: traits and roles.

PubMed

López-Sáez, Mercedes; Morales, J Francisco; Lisbona, Ana

2008-11-01

The aim of this study is twofold: to determine whether (and how) gender stereotypes have changed over time through a comparison of two different sets of data collected in 1993 (N=1255) and 2001 (N=1255) from a representative sample of the Spanish population, and to examine the relation between gender traits and roles and its stability over time. In addition, special attention is paid to the psychometric properties of the measures of gender traits and roles used in the study. The content of gender stereotypes was found to remain stable over the target period of time, confirming the classical typology (a higher assignment of expressive-communal traits to women and of instrumental-agentic traits to men). The structure of the gender-role questionnaire allows us to distinguish between family-role and work-role stereotyping. Gender-role stereotyping shows a marked decline between 1993 and 2001, a result that contrasts with the stability of trait-role stereotyping. The fact that a very low correlation is observed at the two time points between these two components of gender stereotyping strongly suggests their independence.

The role of the charge nurse manager: a descriptive exploratory study.

PubMed

McCallin, A M; Frankson, C

2010-04-01

To explore the charge nurse manager role. Management in nursing is increasingly challenging. Restructuring of organizations has had an impact on the scope of the charge nurse manager role that has expanded so that managers are now expected to be leaders. If role preparation is inadequate, potential for role confusion and role stress increases, undermining role effectiveness in this key senior nursing position. This descriptive exploratory study investigated the experiences of charge nurse managers. Twelve nurse managers from an acute care hospital in New Zealand were interviewed. Data were analysed thematically. Three themes, role ambiguity, business management deficit and role overload emerged. It was evident that charge nurse managers were appointed into a management role with clinical expertise but without management skills. Findings suggest that role preparation should include postgraduate education and business management training. Role induction requires a formal organizational management trainee programme and ongoing supportive clinical supervision. New approaches to charge nurse manager role development are needed. Organizations must provide formal structural support to facilitate management development. The profession needs to promote succession planning that would reduce these longstanding problems.

Defining the doula's role: fostering relational autonomy.

Meadow, Sandra L

2015-12-01

Training organizations as well as academic and popular literature provide ambiguous or ethically contentious characterizations of the role of the birth doula, a non-clinical role assisting women in pregnancy and birth with information and physical and emotional support. Doulas have been criticized for attempting to impose their own agendas on their clients and for interfering with the relationship between women and their medical caregivers. To develop a theoretically grounded model of the birth doula's role to guide constructive practice and refute some training organizations' and doulas' adoption of an active 'advocacy' role with clients that can lead to inappropriate practices. Apply the theoretical framework of relational autonomy to the components of the work that doulas perform with their clients. The conceptual framework of relational autonomy recognizes the social context in which women make choices about their care in pregnancy and birth, instead of assuming that autonomy is exercised in isolation. To support this understanding of autonomy, a relational model emphasizes women's skills development, self-confidence and recognition of the social context for decisions. Highlighting these aspects of exercising autonomy reduces the potential for the doula to seek to influence her client. The doula's role is reframed as one of facilitating patient engagement and shared decision-making. © 2014 John Wiley & Sons Ltd.

The Role of Notch3 in Cancer.

The Notch family is a highly conserved gene group that regulates cell-cell interaction, embryogenesis, and tissue commitment. This review article focuses on the third Notch family subtype, Notch3. Regulation via Notch3 signaling was first implicated in vasculogenesis. However, more recent findings suggest that Notch3 signaling may play an important role in oncogenesis, tumor maintenance, and resistance to chemotherapy. Its role is mainly oncogenic, although in some cancers it appears to be tumor suppressive. Despite the wealth of published literature, it remains relatively underexplored and requires further research to shed more light on its role in cancer development, determine its tissue-specific function, and elaborate novel treatment strategies. Herein we summarize the role of Notch3 in cancer, possible mechanisms of its action, and current cancer treatment strategies targeting Notch3 signaling. The Notch family is a highly conserved gene group that regulates cell-cell interaction, embryogenesis, and tissue commitment. This review summarizes the existing data on the third subtype of the Notch family, Notch3. The role of Notch3 in different types of cancers is discussed, as well as implications of its modification and new strategies to affect Notch3 signaling activity. © AlphaMed Press 2018.

Two contrasting perspectives on the effects of multiple roles; the 'role overload hypothesis' and the 'role enhancement model', have been proposed to predict variations in health. The aim of this study was to evaluate the impact of multiple roles on all-cause mortality in Japan where gender roles are currently changing. A total of 76,758 individuals from the Japan Collaborative Cohort Study were followed for an average of 15.7 years. Hazard ratios (HRs) with 95% confidence intervals were calculated from proportional hazard models to estimate the risk of all-cause mortality according to multiple roles (spouse, parent and worker, and combinations of these roles). After adjusting for potential confounding factors, the risks of all-cause mortality were elevated among men and women without a role. The number of roles was also associated with all-cause mortality risk, showing the highest risk values among those with no roles compared with those with triple roles (HR: 1.66 in men and 1.78 in women). The impact of the lack of a role was generally greater in men than in women and also in the middle-aged than in the elderly. A beneficial effect of multiple roles was suggested among Japanese. The fewer roles they had, the higher all-cause mortality risks were observed. The risk values of those with fewer roles were generally higher in men than in women and also in the middle-aged than in the elderly, partially explained by greater role overload in middle-aged women than other groups in Japan.

To identify and describe new roles for medical assistants (MAs) in innovative care models that improve care while providing training and career advancement opportunities for MAs. Primary data collected at 15 case study sites; 173 key informant interviews and de-identified secondary data on staffing, wages, patient satisfaction, and health outcomes. Researchers used snowball sampling and screening calls to identify 15 organizations using MAs in new roles. Conducted site visits from 2010 to 2012 and updated information in 2014. Thematic analysis explored key topics: factors driving MA role innovation, role description, training required, and wage gains. Categorized outcome data in patient and staff satisfaction, quality of care, and efficiency. New MA roles included health coach, medical scribe, dual role translator, health navigator, panel manager, cross-trained flexible role, and supervisor. Implementation of new roles required extensive training. MA incentives and enhanced compensation varied by role type. New MA roles are part of a larger attempt to reform workflow and relieve primary care providers. Despite some evidence of success, spread has been limited. Key challenges to adoption included leadership and provider resistance to change, cost of additional MA training, and lack of reimbursement for nonbillable services. © Health Research and Educational Trust.

Objective To define the role and education of the traditional pharmacist who supports the needs of the veterinarian (hereafter referred to as veterinary pharmacist) and a pharmacist who practices solely in veterinary pharmacy (here after referred to as veterinary pharmacy specialist). Methods The Delphi technique involving 7 panels of 143 experts was employed to reach consensus on the definition of the roles and education of the veterinary pharmacist and veterinary pharmacy specialist. Results The veterinary pharmacy specialist's role included dispensing medications, complying with regulations, advocating for quality therapeutic practices, and providing consultative services, research, and education. The perceived role of the veterinary pharmacist was viewed as being somewhat narrower. Compared to veterinary pharmacists, a more in-depth education in veterinary medicine was viewed as essential to the role development of veterinary pharmacy specialists. Conclusions The authors hope their research will promote widespread awareness of the emerging field of veterinary pharmacy and encourage schools to offer increased access to clinically relevant professional training programs.

Immunomodulation: A definitive role of microRNA-142.

PubMed

Sharma, Salil

2017-12-01

Majority of microRNAs are evolutionarily conserved in vertebrates. This is suggestive of their similar roles in regulation of gene networks. In addition to their conserved mature sequences and regulatory roles, a few microRNAs show very cell or tissue specific expression. These microRNAs are highly enriched in some cell types or organs. One such microRNA is microRNA-142 (miR-142). The classical stem-loop structure of miR142 encodes for two species of mature microRNAs; miR142-5p and miR142-3p. MiR-142 is abundant in cells of hematopoietic origin, and therefore, aptly plays a role in lineage differentiation of hematopoietic cells. Interestingly, over the years, miR-142 has gained considerable attention for its quintessential role in regulating immune response. This mini-review discusses the important functional roles of miR-142 in inflammatory and immune response in different physiological and disease setting. Copyright © 2017 Elsevier Ltd.

Qualitative Evaluation of a Role Play Bullying Simulation.

PubMed

Gillespie, Gordon L; Brown, Kathryn; Grubb, Paula; Shay, Amy; Montoya, Karen

Bullying against nurses is becoming a pervasive problem. In this article, a role play simulation designed for undergraduate nursing students is described. In addition, the evaluation findings from a subsample of students who participated in a role play simulation addressing bullying behaviors are reported. Focus group sessions were completed with a subset of eight students who participated in the intervention. Sessions were audiorecorded, transcribed verbatim, and analyzed using Colaizzi's procedural steps for qualitative analysis. Themes derived from the data were "The Experience of Being Bullied", "Implementation of the Program", "Desired Outcome of the Program", and "Context of Bullying in the Nursing Profession". Role play simulation was an effective and active learning strategy to diffuse education on bullying in nursing practice. Bullying in nursing was identified as a problem worthy of incorporation into the undergraduate nursing curriculum. To further enhance the learning experience with role play simulation, adequate briefing instructions, opportunity to opt out of the role play, and comprehensive debriefing are essential.

The present study evaluated the antinociceptive effect of (1→3),(1→6)-linked β-glucan (GL) isolated from Pleurotus pulmonarius (Fr.) Quel. in mice and its possible mechanism of action. Intraperitoneal administration of GL inhibited glutamate-induced licking with an ID(50) of 0.34 mg/kg and inhibition of 96% ± 3%. The treatment of animals with GL (1 mg/kg i.p.) inhibited nociception induced by intrathecal injection of N-methyl-D-aspartic acid, α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid, kainate and interleukin -1β in 67% ± 13%, 89% ± 11%, 74% ± 9%, and 75% ± 7%, respectively, but not the nociceptive response induced by (±)-1-aminocyclopentane-trans-1,3-dicarboxylic acid, substance P, and tumor necrosis factor-α. Moreover, GL (30 mg/kg i.p.) also reduced mechanical allodynia caused by partial sciatic nerve ligation for 2 hours, with inhibition of 47% ± 10% observed 0.5 hours after treatment. When given chronically (twice a day) over 7 days, GL reversed the mechanical allodynia caused by partial sciatic nerve ligation (inhibition of 45% ± 13% to 60% ± 8%). Interestingly, GL did not affect the locomotor activity of mice in an open field test with doses that produce antinociceptive effects. Our findings show that GL inhibits acute and neuropathic pain in mice through mechanisms that involve the inhibition of ionotropic glutamate receptors and the interleukin -1β pathway. This article presents the antinociceptive activity of GL in acute and neuropathic pain with participation of ionotropic glutamate receptors and pro-inflammatory cytokines (interleukin-1β). After further experiments, this compound may represent a new pharmacological agent for the treatment of clinical pain. Copyright © 2010 American Pain Society. Published by Elsevier Inc.

Social support plays a role in the attitude that people have towards taking an active role in medical decision-making.

PubMed

Brabers, Anne E M; de Jong, Judith D; Groenewegen, Peter P; van Dijk, Liset

2016-09-21

There is a growing emphasis towards including patients in medical decision-making. However, not all patients are actively involved in such decisions. Research has so far focused mainly on the influence of patient characteristics on preferences for active involvement. However, it can be argued that a patient's social context has to be taken into account as well, because social norms and resources affect behaviour. This study aims to examine the role of social resources, in the form of the availability of informational and emotional support, on the attitude towards taking an active role in medical decision-making. A questionnaire was sent to members of the Dutch Health Care Consumer Panel (response 70 %; n = 1300) in June 2013. A regression model was then used to estimate the relation between medical and lay informational support and emotional support and the attitude towards taking an active role in medical decision-making. Availability of emotional support is positively related to the attitude towards taking an active role in medical decision-making only in people with a low level of education, not in persons with a middle and high level of education. The latter have a more positive attitude towards taking an active role in medical decision-making, irrespective of the level of emotional support available. People with better access to medical informational support have a more positive attitude towards taking an active role in medical decision-making; but no significant association was found for lay informational support. This study shows that social resources are associated with the attitude towards taking an active role in medical decision-making. Strategies aimed at increasing patient involvement have to address this.

Simplified process model discovery based on role-oriented genetic mining.

PubMed

Zhao, Weidong; Liu, Xi; Dai, Weihui

2014-01-01

Process mining is automated acquisition of process models from event logs. Although many process mining techniques have been developed, most of them are based on control flow. Meanwhile, the existing role-oriented process mining methods focus on correctness and integrity of roles while ignoring role complexity of the process model, which directly impacts understandability and quality of the model. To address these problems, we propose a genetic programming approach to mine the simplified process model. Using a new metric of process complexity in terms of roles as the fitness function, we can find simpler process models. The new role complexity metric of process models is designed from role cohesion and coupling, and applied to discover roles in process models. Moreover, the higher fitness derived from role complexity metric also provides a guideline for redesigning process models. Finally, we conduct case study and experiments to show that the proposed method is more effective for streamlining the process by comparing with related studies.

Role of mitochondrial oxidative stress in hypertension

PubMed Central

Ungvari, Zoltan

2013-01-01

Based on mosaic theory, hypertension is a multifactorial disorder that develops because of genetic, environmental, anatomical, adaptive neural, endocrine, humoral, and hemodynamic factors. It has been recently proposed that oxidative stress may contribute to all of these factors and production of reactive oxygen species (ROS) play an important role in the development of hypertension. Previous studies focusing on the role of vascular NADPH oxidases provided strong support of this concept. Although mitochondria represent one of the most significant sources of cellular ROS generation, the regulation of mitochondrial ROS generation in the cardiovascular system and its pathophysiological role in hypertension are much less understood. In this review, the role of mitochondrial oxidative stress in the pathophysiology of hypertension and cross talk between angiotensin II signaling, pathways involved in mechanotransduction, NADPH oxidases, and mitochondria-derived ROS are considered. The possible benefits of therapeutic strategies that have the potential to attenuate mitochondrial oxidative stress for the prevention/treatment of hypertension are also discussed. PMID:24043248

Role of inflammation in the aging bones.

PubMed

Abdelmagid, Samir M; Barbe, Mary F; Safadi, Fayez F

2015-02-15

Chronic inflammation in aging is characterized by increased inflammatory cytokines, bone loss, decreased adaptation, and defective tissue repair in response to injury. Aging leads to inherent changes in mesenchymal stem cell (MSC) differentiation, resulting in impaired osteoblastogenesis. Also, the pro-inflammatory cytokines increase with aging, leading to enhanced myelopoiesis and osteoclastogenesis. Bone marrow macrophages (BMMs) play pivotal roles in osteoblast differentiation, the maintenance of hematopoietic stem cells (HSCs), and subsequent bone repair. However, during aging, little is known about the role of macrophages in the differentiation and function of MSC and HSC. Aged mammals have higher circulating pro-inflammatory cytokines than young adults, supporting the hypothesis of increased inflammation with aging. This review will aid in the understanding of the potential role(s) of pro-inflammatory (M1) and anti-inflammatory (M2) macrophages in differentiation and function of osteoblasts and osteoclasts in relation to aging.

2013-02-01

To identify the perceived roles and responsibilities of clinicians during care transitions of older adults. Qualitative study involving 1-hour in-depth semistructured interviews. Audiotapes of interviews were transcribed, coded, and analyzed, and themes and subthemes were generated. An acute care hospital, a skilled nursing facility, two community-based outpatient practices, and one home healthcare agency. Forty healthcare professionals directly involved in care transitions of older adults (18 physicians, 11 home healthcare administrative and field staff, four social workers, three nurse practitioners, three physician assistants, and one hospital case manager). Perspectives of healthcare professionals regarding clinicians' roles and responsibilities during care transitions were examined and described. Content analysis revealed several themes: components of clinicians' roles during care transitions; congruence between self- and others' perceived ideal roles but incongruence between ideal and routine roles; ambiguity in accountability in the postdischarge period; factors prompting clinicians to act closer to ideal roles; and barriers to performing ideal roles. A conceptual framework was created to summarize clinicians' roles during care transitions. This study reports differences between what healthcare professionals perceive as ideal roles of clinicians during care transitions and what clinicians actually do routinely. Certain patient and clinician factors prompt clinicians to act closer to the ideal roles. Multiple barriers interfere with consistent practice of ideal roles. Future investigations could evaluate interventions targeting various components of the conceptual framework and relevant outcomes. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

Role of plant hormones in plant defence responses.

PubMed

Bari, Rajendra; Jones, Jonathan D G

2009-03-01

Plant hormones play important roles in regulating developmental processes and signaling networks involved in plant responses to a wide range of biotic and abiotic stresses. Significant progress has been made in identifying the key components and understanding the role of salicylic acid (SA), jasmonates (JA) and ethylene (ET) in plant responses to biotic stresses. Recent studies indicate that other hormones such as abscisic acid (ABA), auxin, gibberellic acid (GA), cytokinin (CK), brassinosteroids (BR) and peptide hormones are also implicated in plant defence signaling pathways but their role in plant defence is less well studied. Here, we review recent advances made in understanding the role of these hormones in modulating plant defence responses against various diseases and pests.

1999-01-01

This article explores the role of the clinical nurse specialist (CNS) in school health. School nurse roles and responsibilities are expanding from their original emphasis on providing direct care and education to children and their parents to community-oriented care. CNS roles and practice areas have expanded to fill needs in a variety of settings, with a variety of clients. The identified CNS roles of clinician, educator, consultant, researcher, and leader/manager provide a comprehensive approach to providing school health services directly to individuals and indirectly through community-oriented care. A CNS's expertise is essential to assist with providing comprehensive care to students, their families, and the community through comprehensive school health services.

Role of thymus-eicosanoids in the immune response.

PubMed

Juzan, M; Hostein, I; Gualde, N

1992-08-01

The present review deals with the role(s) of thymus-eicosanoids in the immune response. It reports the production of cyclooxygenase and lipoxygenase metabolites of arachidonic acid by cells of the thymus microenvironment and the role(s) of these eicosanoids in the differentiation and the maturation of immature T-cells. The possibility that these products may be involved in tolerance to self is discussed. Briefly, it is likely that cells from the monocyte-macrophage lineage which constitute a part of the thymus microenvironment could contribute to the education of immature thymocytes by both presenting self-antigens and producing eicosanoids. Tolerance to self might result from PGE2-driven apoptosis and/or LTB4-induced generation of suppressor cells.

Role conflict and satisfaction in the work-family context: Age differences in the moderating effect of role commitment.

2015-03-01

This study examined age differences in the buffering effects of role commitment on the associations between role conflicts and satisfaction from the within-domain and cross-domain perspectives. Eighty-five working mothers participated in the study. Multiple regression analyses revealed that work conflicts were negatively associated with job satisfaction of younger employees but not older employees. Commitment to both work and family buffered against the negative association between family conflicts and family satisfaction for older employees but not younger employees. These findings highlight the importance of role commitment for working mothers across adulthood to cope with the demands in the work-family interface. © 2015 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

Macrophages: Their Emerging Roles in Bone

PubMed Central

Sinder, Benjamin P; Pettit, Allison R; McCauley, Laurie K

2016-01-01

Macrophages are present in nearly all tissues and are critical for development, homeostasis, and regeneration. Resident tissue macrophages of bone, termed osteal macrophages, are recently classified myeloid cells that are distinct from osteoclasts. Osteal macrophages are located immediately adjacent to osteoblasts, regulate bone formation, and play diverse roles in skeletal homeostasis. Genetic or pharmacological modulation of macrophages in vivo results in significant bone phenotypes, and these phenotypes depend on which macrophage subsets are altered. Macrophages are also key mediators of osseous wound healing and fracture repair, with distinct roles at various stages of the repair process. A central function of macrophages is their phagocytic ability. Each day, billions of cells die in the body and efferocytosis (phagocytosis of apoptotic cells) is a critical process in both clearing dead cells and recruitment of replacement progenitor cells to maintain homeostasis. Recent data suggest a role for efferocytosis in bone biology and these new mechanisms are outlined. Finally, although macrophages have an established role in primary tumors, emerging evidence suggests that macrophages in bone support cancers which preferentially metastasize to the skeleton. Collectively, this developing area of osteoimmunology raises new questions and promises to provide novel insights into pathophysiologic conditions as well as therapeutic and regenerative approaches vital for skeletal health.

Role-taking ability and social behavior in deaf school children.

PubMed

Cates, D S; Shontz, F C

1990-07-01

This study assessed the relationship between role-taking skill and social-emotional adjustment in deaf children. Twenty-three prelingually deafened boys and girls between 7 and 14 years of age were administered a role-taking task, surreptitious behavioral measures of helping and altruism, and a measure of nonverbal intelligence. In addition, two professionals experienced in working with deaf children rated the social and emotional adjustment, language/communication skills and role-taking ability of the participants. Performance on the role-taking task correlated positively with ratings of emotional adjustment, self-image, communicative effectiveness and role-taking skill. Role-taking performance, however, was not reliably related to any of the measures of social behavior. The study also considered several factors which may account for the apparent independence of role-taking and social behavior.

Why nursing has not embraced the clinician--scientist role.

PubMed

Mackay, Martha

2009-10-01

Reasons for the limited uptake of the clinician-scientist role within nursing are examined, specifically: the lack of consensus about the nature of nursing science; the varying approaches to epistemology; and the influence of post-modern thought on knowledge development in nursing. It is suggested that under-development of this role may be remedied by achieving agreement that science is a necessary, worthy pursuit for nursing, and that rigorous science conducted from a clinical perspective serves nursing well. Straddling practice and research is a powerful strategy for ensuring relevant research while forging strong links with practice. The clinician-scientist role, typically requiring a 75:25 ratio between research and clinical activities, is well established in medicine. Nursing, however, has been slow to institute the role; it is rare within North America, Australia, and western European countries, and almost non-existent outside those areas. Beyond structural obstacles, philosophical issues may explain nursing's reluctance to implement the role. Following a survey of clinician-scientist roles throughout the world, the nature of nursing science and epistemology, and the influence of post-modern thought on nursing attitudes to research are examined with respect to their influence on this role. The nurse clinician-scientist role holds promise for making strides in clinically relevant research, and for accelerating the knowledge cycle from clinical problem to research question to change in clinical practice.

The role of WOX genes in flower development.

PubMed

Costanzo, Enrico; Trehin, Christophe; Vandenbussche, Michiel

2014-11-01

WOX (Wuschel-like homeobOX) genes form a family of plant-specific HOMEODOMAIN transcription factors, the members of which play important developmental roles in a diverse range of processes. WOX genes were first identified as determining cell fate during embryo development, as well as playing important roles in maintaining stem cell niches in the plant. In recent years, new roles have been identified in plant architecture and organ development, particularly at the flower level. In this review, the role of WOX genes in flower development and flower architecture is highlighted, as evidenced from data obtained in the last few years. The roles played by WOX genes in different species and different flower organs are compared, and differential functional recruitment of WOX genes during flower evolution is considered. This review compares available data concerning the role of WOX genes in flower and organ architecture among different species of angiosperms, including representatives of monocots and eudicots (rosids and asterids). These comparative data highlight the usefulness of the WOX gene family for evo-devo studies of floral development. © The Author 2014.

Uncovering middle managers' role in healthcare innovation implementation

PubMed Central

2012-01-01

Background Middle managers have received little attention in extant health services research, yet they may have a key role in healthcare innovation implementation. The gap between evidence of effective care and practice may be attributed in part to poor healthcare innovation implementation. Investigating middle managers' role in healthcare innovation implementation may reveal an opportunity for improvement. In this paper, we present a theory of middle managers' role in healthcare innovation implementation to fill the gap in the literature and to stimulate research that empirically examines middle managers' influence on innovation implementation in healthcare organizations. Discussion Extant healthcare innovation implementation research has primarily focused on the roles of physicians and top managers. Largely overlooked is the role of middle managers. We suggest that middle managers influence healthcare innovation implementation by diffusing information, synthesizing information, mediating between strategy and day-to-day activities, and selling innovation implementation. Summary Teamwork designs have become popular in healthcare organizations. Because middle managers oversee these team initiatives, their potential to influence innovation implementation has grown. Future research should investigate middle managers' role in healthcare innovation implementation. Findings may aid top managers in leveraging middle managers' influence to improve the effectiveness of healthcare innovation implementation. PMID:22472001

What are the roles of clinical nurses and midwife specialists?

PubMed

Wickham, Sheelagh

Research shows the increasing part the Clinical Nurse Specialist (CNS) plays in healthcare today. But what does a CNS actually do in their day-to day-work? This study, set in the Republic of Ireland, aimed to explore the CNS and clinical midwife specialist (CMS) roles in practice. Quantitative methodology was used to explore the roles and activities of the CNS and CMS. Following ethics approval, a valid and reliable questionnaire was circulated to the total population of CNS/CMS in Ireland. The data were analysed using SPSS. This study articulates the individual role elements and activity level. The findings show the CNS/CMS to be active in the roles of researcher, educator, communicator, change agent, leader and clinical specialist, but the level of activity varies between different roles and individual role elements. The CNS/CMS is seen as a valuable resource in health care today and has potential to have a positive effect on patient care. The majority of CNS/CMSs are active in varying roles but the analysis shows lesser activity in some areas, such as research. The findings merit further study on role activity and possible variables that influence role activity.

Zeelie, S C; Bornman, J E; Botes, A C

2003-12-01

This article reports on role player expectations regarding the education of nursing research. The importance of the role player expectations are two-fold: firstly as a factor in the external environment influencing and guiding the formulation phase of the development of standards and secondly, due to the clear indications of problems regarding nursing research in the nursing profession in literature. The role player expectations were elicited using a qualitative, exploratory and contextual design. The role player population included nurse educators, nurses in managerial, clinical and research positions, students and the medical profession. The data was gathered using the naïve sketches and qualitative data analysis was done using Morse & Field's approach (1996:103-107) in combination with Tesch's data analysis approach as cited by Creswell (1994:154-156). Sixty initial categories were narrowed down to six final categories, which are the research learning programme, personnel, students, departmental policies, funding and support systems. The role player expectations were elicited as part of a research study aiming tot develop a self-evaluation system for quality assurance in nursing research and as such, the role player expectations plays a pivotal role in the development of standards for the self-evaluation system.

Background Family support is important in diabetes self-management. However, children as providers of support have received little attention. This study examines the role of children in their parents’ diabetes self-management, diet, and exercise. Methods This research used community-based participatory research principles. Researchers conducted semi-structured parallel interviews of 24 Latino and African-American adults with diabetes and with a child (age 10–17 years) in their home (2004–06). Interviews were transcribed, coded, and analyzed for themes (2004–07). Results Adults and children perceived that children play many roles related to adults’ diabetes self-management. Parents described children as monitoring parents’ dietary intake and reminding them what they should not be eating. Some children helped with shopping and meal preparation. Families described children reminding parents to exercise and exercising with their parent. Children reminded parents about medications and assisted with tasks such as checking blood sugar. Parents and children perceived that children played a role in tempting parents to stray from their diabetes diet, because children's diets included food that parents desired but tried to avoid. Conclusion Children and parents perceived that children have many roles in both supporting and undermining adults’ diabetes self-management. There is more to learn about the bidirectional relationships between adults and children in this setting and the most beneficial roles children can play. Health-care providers should encourage family lifestyle change, strengthen social support for families and direct children toward roles that are beneficial for both parent and child and do not place an unreasonable level of responsibility on the child.

Tribbles role in reproduction.

2015-10-01

Tribbles (TRIB) proteins, a family of evolutionary conserved psuedokinase proteins, modulate various signalling pathways within the cell. The regulatory roles of TRIB make them an important part of a number of biological processes ranging from cell proliferation to metabolism, immunity, inflammation and carcinogenesis. Innate immune system plays a pivotal role during the regulation of reproductive processes that allows successful creation of an offspring. Its involvement initiates from fertilization of the oocyte by spermatozoon and lasts throughout early embryonic development, pregnancy and labour. Therefore, there is a close cooperation between the reproductive system and the innate immune system. Evidence from our lab has demonstrated that improper activation of the innate immune system can reduce embryo implantation, thus leading to infertility. Therefore, control mechanisms regulating the innate immune system function can be critical for successful reproductive events. © 2015 Authors; published by Portland Press Limited.

Predictors of dating violence among Chinese adolescents: the role of gender-role beliefs and justification of violence.

Shen, April Chiung-Tao; Chiu, Marcus Yu-Lung; Gao, Jianxiu

2012-04-01

In Chinese societies, violence among adolescent dating partners remains a largely ignored and invisible phenomenon. The goal of this study is to examine the relationships among gender-role beliefs, attitudes justifying dating violence, and the experiences of dating-violence perpetration and victimization among Chinese adolescents. This study has used self-reporting measures to collect data from a probability sample of 976 adolescents (mean age = 15.9) in three Chinese societies: Taiwan, Hong Kong, and Shanghai. Research results reveal a high prevalence of dating violence (including physical violence, sexual violence, and controlling behavior) among Chinese adolescents with dating experience: the perpetration rate is 27.3% and the victimization rate is 39%. Study results demonstrate that adolescents who endorse traditional gender-role beliefs tend to view dating violence as acceptable behavior. Boys' endorsement of traditional gender roles, boys' attitudes justifying boy-on-girl violence, and boys' attitudes against girl-on-boy violence predict boys' actual sexual-violence behavior. Moreover, boys' attitudes justifying boy-on-girl dating violence is the strongest predictor of boys' perpetration of physical and sexual dating violence. This study also shows that boys' hostility is a significant predictor of boys' controlling behavior. Programs for preventing dating violence should include components designed to challenge traditional gender-role beliefs and attitudes justifying dating violence.

Grandparenting Roles and Volunteer Activity

PubMed Central

Jendrek, Margaret Platt

2016-01-01

Objectives. We examine whether grandparenting roles are related to formal volunteering among older adults. Method. Logistic regression is used to examine the likelihood of volunteering based on grandchild care using data from the 2004 wave of the Health and Retirement Study (n = 13,785). Longitudinal analyses utilize treatment effects models to examine changes in volunteering for grandparents who begin nonresidential grandchild care between the 2004 and 2008 waves (n = 10,811). Results. Results show that grandparents raising coresidential grandchildren have lower odds of volunteering than grandparents providing no regular grandchild care. However, grandparents who provide nonresidential grandchild care are more likely to volunteer than grandparents not providing grandchild care and those raising a coresidential grandchild. Grandparents who provide nonresidential care for grandchildren engage in more volunteering before assuming grandchild care, and their volunteerism increases after becoming a caregiver for a grandchild. Discussion. Consistent with resource theory and the accumulation of roles, providing nonresidential grandchild care may draw grandparents into formal volunteer activity. The lower human capital resources evidenced by grandparents raising coresidential grandchildren may play a role in their lower likelihood of formal volunteering. PMID:24721748

To explore the nurse's role in the process of medication management and identify the challenges associated with safe medication management in contemporary clinical practice. Medication errors have been a long-standing factor affecting consumer safety. The nursing profession has been identified as essential to the promotion of patient safety. A review of literature on medication errors and the use of electronic prescribing in medication errors. Medication management requires a multidisciplinary approach and interdisciplinary communication is essential to reduce medication errors. Information technologies can help to reduce some medication errors through eradication of transcription and dosing errors. Nurses must play a major role in the design of computerized medication systems to ensure a smooth transition to such as system. The nurses' roles in medication management cannot be over-emphasized. This is particularly true when designing a computerized medication system. The adoption of safety measures during decision making that parallel those of the aviation industry safety procedures can provide some strategies to prevent medication error. Innovations in information technology offer potential mechanisms to avert adverse events in medication management for nurses. © 2010 The Authors. Journal compilation © 2010 Blackwell Publishing Ltd.

Sex-role attitudes across two cultures: United States and India.

PubMed

Rao, V V; Rao, V N

1985-12-01

This study tests whether students from India hold more traditional sex role attitudes compared to students from the US, whether women from either country hold more liberal sex role attitudes than males, and whether socioeconomic and demographic factors are better predictors of sex role attitudes among women of either culture. Data were obtained in 1978 from a sample of 409 undergraduate students from three Mississippi colleges in the US and 419 undergraduate and graduate students from three educational institutions in Andhra Pradesh, India. Sex role attitudes are measured by scaling developed by Scanzoni (1975). Out of a total possible score of 100, the mean values are 69.09 for the US sample and 53.62 for the Indian sample. Differences between the means for all 20 sex role attitudes are statistically significant. Results indicate that US females and Indian females had less traditional sex role attitudes than their respective counterparts. Mother role, wife role, father role, and total sex role attitude were more traditional among males in India compared to males in the US and among females in India compared to females in the US. More traditional attitudes were held by males in India with lower educated fathers and unemployed mothers. Religion was the only variable significantly related to Indian female students. In the US, traditional sex role attitudes of males were significantly related to high maternal income and residence in urban areas. More traditional sex role attitudes among US females were related to increasing age and marital status. Stepwise analysis reveals that the most powerful explanatory factors were sex and mother's occupation among Indian students and sex, father's income, and year in college among US students. What little variance was explained was explained by more variables in the US sample, and the best model predictors explained more variance in the US sample.

Taurine and its neuroprotective role.

PubMed

Kumari, Neeta; Prentice, Howard; Wu, Jang-Yen

2013-01-01

Taurine plays multiple roles in the CNS including acting as a -neuro-modulator, an osmoregulator, a regulator of cytoplasmic calcium levels, a trophic factor in development, and a neuroprotectant. In neurons taurine has been shown to prevent mitochondrial dysfunction and to protect against endoplasmic reticulum (ER) stress associated with neurological disorders. In cortical neurons in culture taurine protects against excitotoxicity through reversing an increase in levels of key ER signaling components including eIF-2-alpha and cleaved ATF6. The role of communication between the ER and mitochondrion is also important and examples are presented of protection by taurine against ER stress together with prevention of subsequent mitochondrial initiated apoptosis.

The journalist's role in bioethics.

PubMed

Rosenfeld, A

1999-04-01

In the late 1950s and early 1960s, emerging advances in the biomedical sciences raised insufficiently noticed ethical issues, prompting science reporters to serve as a sort of Early Warning System. As awareness of bioethical issues increased rapidly everywhere, and bioethics itself arrived as a recognized discipline, the need for this early-warning press role has clearly diminished. A secondary but important role for the science journalist is that of investigative reporter/whistleblower, as in the Tuskegee syphilis trials and the government's secret plutonium experiments. Because the general public gets most of its information from the popular media, ways are suggested for journalists and bioethicists to work together.

2009-02-01

To determine the importance of role overload (the extent to which a person feels overwhelmed by her total responsibilities) relative to other known social determinants of women's mental health. A Canadian national, random sample, cross-sectional telephone survey in 2003 assessed the association among role overload, types and quality of roles (parent, employee, spouse), sociodemographics, and mental health (using the SF-12) using linear regression. Analysis included 716 women aged 25-54 who indicated that their youngest child living in the household was aged < or =17 years. Perceptions of greater role overload were associated with poorer mental health (p < 0.0001). Women working <35 hours per week (p = 0.04) or 35-40 hours per week (p 5 0.002) reported better mental health than nonemployed women, as did women with the highest annual household income ($70,000+)(p = 0.001). Also associated with better mental health were higher marital status quality scores for both married and single women (p < 0.001), higher job quality scores among employed women (p = 0.02), greater homemaking quality scores among unemployed women (p = 0.03), and women reporting high parental quality (p = 0.04) Role overload showed a stronger relationship to mental health than other sociodemographic variables, including income. Our findings indicate the importance of measuring women's experience of their multiple roles rather than focusing on single roles. More research is warranted on the totality of women's experiences of their many social role obligations.

Gender roles and relationships: Implications for water management

NASA Astrophysics Data System (ADS)

Peter, G.

This study mainstreams gender at household level by showing how the gendered roles and relations between women and men influence access, allocation and use of resources in a rural community, Makhosini, in Swaziland. Implications of the identified gender roles and relationships for water management in Swaziland are highlighted. The working hypotheses of this study are (i) that gender-neutral development initiatives will benefit equally women and men at household level; and (ii) in Swaziland the trend toward irrigated agriculture for food security will have unequal impacts on men and women as access, allocation and use of key resources is highly gendered, privileging men as the value of the resource increases. In this study, a questionnaire was administered to sampled male and female heads of household as well as women under male heads. The heads were asked to indicate the roles they play and key decisions they make in resource use as heads of households. The women under male heads were also asked to indicate their roles and key decision responsibilities. The key resources considered were land and crops produced. Comparative analysis on roles and decisions made as well as access and use of resources and production was done by gender and between the women groups. The results show marked gender differences within households and across resources. Men were overwhelmingly involved in productive roles, giving low priority to reproductive roles. In contrast, priority of women’s roles were reproductive in nature. The key findings are that there were no significant differences in the roles of men and women as heads of households. Women as heads of households assume the same roles as those of men heads suggesting relative gender-neutrality. Also all women played “double-day” roles. However, the data reveals that men dominate decisions on crops to be grown, inputs to be used, disposal of the products and use of income obtained. Only a small percentage of women claimed

Qualitative Evaluation of a Role Play Bullying Simulation

Gillespie, Gordon L.; Brown, Kathryn; Grubb, Paula; Shay, Amy; Montoya, Karen

2015-01-01

Bullying against nurses is becoming a pervasive problem. In this article, a role play simulation designed for undergraduate nursing students is described. In addition, the evaluation findings from a subsample of students who participated in a role play simulation addressing bullying behaviors are reported. Focus group sessions were completed with a subset of eight students who participated in the intervention. Sessions were audiorecorded, transcribed verbatim, and analyzed using Colaizzi’s procedural steps for qualitative analysis. Themes derived from the data were “The Experience of Being Bullied”, “Implementation of the Program”, “Desired Outcome of the Program”, and “Context of Bullying in the Nursing Profession”. Role play simulation was an effective and active learning strategy to diffuse education on bullying in nursing practice. Bullying in nursing was identified as a problem worthy of incorporation into the undergraduate nursing curriculum. To further enhance the learning experience with role play simulation, adequate briefing instructions, opportunity to opt out of the role play, and comprehensive debriefing are essential.

David Johnson, J

2014-08-12

Objective: To determine the new roles that physicians will adopt in the near future to adjust to accelerating trends from managed care to outcome-based practice to health care reform to health information technology to the evolving role of health consumers. Methods: Trends and related developments concerning the changing roles of physicians based on prior literature reviews. Results: Six possible roles, traditional, gatekeeper, coach, navigator, informatician and one voice among many, are discussed in terms of physician's centrality, patient autonomy, decision-making and uncertainty, information seeking, satisfaction and outcomes, particularly those related to compliance. Conclusion: A greater understanding of these emerging roles could lead to more efficacious outcomes in our ever changing, increasingly complex medical system. Patients often have little understanding of emerging trends that lead to the development of specialized roles such as hospitalist and navigators and, relatedly, the evolving roles of physicians.

Redefining the school nurse role: an organizational perspective.

PubMed

Chabot, Guylaine; Gagnon, Marie-Pierre; Godin, Gaston

2012-01-01

This paper aims to identify organizational readiness for change towards adoption of a redefined role of the school nurse as a strategic option in the context of a health promoting school approach. This new role is consistent with planned change directed at life habits and life conditions. A questionnaire based on a modified version of the organizational readiness for change (ORC) framework was e-mailed to 122 top and middle managers (response rate of 74 percent) in 42 local health organizations in the Province of Quebec, Canada, during the fall of 2009. In total, 90 percent of participants perceived the proposed role as a solution to fulfil their school health program needs, especially to plan and integrate health promotion projects. The lack of resources and nursing support emerged as factors hampering the capacity of school nurses to play such a role. Additional implications of the ORC framework are needed in order to better address organizational readiness for complex changes in specific health-related settings. Access to information technology and the development of computer skills would help enhance this encompassing role in health promotion. Findings have the potential to better inform health authorities regarding the new role of the school nurse as a strategic option in health promotion. This study also provides an application of the theoretical framework showing the need for additional empirical tests.

The role of the elementary school principal — as perceived by Israeli principals an attempt at role analysis

NASA Astrophysics Data System (ADS)

Kremer, Lya

1983-03-01

The study aimed to define the role of principalship, necessary because of the conflicting loyalties and responsibilities inherent in this role. Four `facets' were used to classify areas of principals' activities, from which a questionnaire was constructed. Ninety principals, representing most of those in the northern part of Israel, participated in the project. On the basis of the questionnaire, they related their role activities to the degree of autonomy they felt they were granted. The findings identify the main factors in the role of the principal and show that principals' activities may be defined according to (a) the degree to which they have been planned in advance or carried out ad hoc; (b) their professional or bureaucratic character; (c) the goals which they are meant to serve and whether their aim is task/product-or person-orientated. In all of these areas the principal can act with varying degrees of autonomy. The techniques employed in obtaining and analyzing the results offer a means of creating and comparing principals' profiles, hence also of indicating the position of the principal in the more general system; producing a typology of administrative styles; and identifying personal styles of principalship.

Relationships of role stressors with organizational citizenship behavior: a meta-analysis.

PubMed

Eatough, Erin M; Chang, Chu-Hsiang; Miloslavic, Stephanie A; Johnson, Russell E

2011-05-01

Several quantitative reviews have documented the negative relationships that role stressors have with task performance. Surprisingly, much less attention has been directed at the impact of role stressors on other aspects of job performance, such as organizational citizenship behavior (OCB). The goal of this study was to therefore estimate the overall relationships of role stressors (i.e., role ambiguity, conflict, and overload) with OCB. A meta-analysis of 42 existing studies indicated that role ambiguity and role conflict were negatively related to OCB and that these relationships were moderated by the target of OCB, type of organization, OCB rating source, and publication status. As expected, role conflict had a stronger negative relationship with OCB than it did with task performance. Finally, we found support for a path model in which job satisfaction mediated relationships of role stressors with OCB and for a positive direct relationship between role overload and OCB.

Role of proline under changing environments

When exposed to stressful conditions, plants accumulate an array of metabolites, particularly amino acids. Amino acids have traditionally been considered as precursors to and constituents of proteins, and play an important role in plant metabolism and development. A large body of data suggests a positive correlation between proline accumulation and plant stress. Proline, an amino acid, plays a highly beneficial role in plants exposed to various stress conditions. Besides acting as an excellent osmolyte, proline plays three major roles during stress, i.e., as a metal chelator, an antioxidative defense molecule and a signaling molecule. Review of the literature indicates that a stressful environment results in an overproduction of proline in plants which in turn imparts stress tolerance by maintaining cell turgor or osmotic balance; stabilizing membranes thereby preventing electrolyte leakage; and bringing concentrations of reactive oxygen species (ROS) within normal ranges, thus preventing oxidative burst in plants. Reports indicate enhanced stress tolerance when proline is supplied exogenously at low concentrations. However, some reports indicate toxic effects of proline when supplied exogenously at higher concentrations. In this article, we review and discuss the effects of exogenous proline on plants exposed to various abiotic stresses. Numerous examples of successful application of exogenous proline to improve stress tolerance are presented. The roles played by exogenous proline under varying environments have been critically examined and reviewed. PMID:22951402

Gender differences in depression across parental roles.

PubMed

Shafer, Kevin; Pace, Garrett T

2015-04-01

Prior research has focused on the relationship between parenthood and psychological well-being, with mixed results. Some studies have also addressed potential gender differences in this relationship, again yielding varied findings. One reason may be methodological choices pursued in these studies, including the lack of focus on combined parental roles (for example, biological parent and stepparent). The authors used data from the National Longitudinal Survey of Youth, 1979 (N = 6,276) and multinomial treatment models to address how combined roles influence depressive symptoms in mothers and fathers. Further, they explored potential gender differences. Their results indicated that having multiple parental roles is negatively associated with psychological well-being for both men and women, whereas childlessness is more negative for women, and specific parental role combinations affect mothers and fathers differently. Within the context of changing family structure in the United States, these results have important implications for social workers and other mental health professionals-particularly with regard to screening for depression among parents, who are less likely to seek mental health counseling than childless adults.

Dimensions of the transition service coordinator role.

PubMed

Betz, Cecily L; Redcay, Gay

2005-01-01

This article describes the development and implementation of an innovative advanced practice role, as a transition service coordinator for nurses who work with adolescents with special healthcare needs. Transition services for adolescents with special healthcare needs is an area of growing clinical need requiring that all healthcare professionals, including advanced practice nurses develop new clinical knowledge and skills to practice effectively. This emerging specialty area will require advanced practice nurses to provide direct services blending both pediatric and adult healthcare needs and to function in advanced practice roles such as case managers who can ensure the coordination of services between these two very different systems of care while promoting the youth's acquisition of goals for adulthood. This nursing role was first created to provide and coordinate transition services to youth seen in a piloted clinic titled Creating Healthy Futures. This article describes the various components of this nursing role that incorporated the advanced practice dimensions of clinical expert, consultant, change agent, leader, researcher, and educator that can be replicated in other clinical settings.

Role modeling excellence in clinical nursing practice.

Perry, R N Beth

2009-01-01

Role modeling excellence in clinical nursing practice is the focus of this paper. The phenomenological research study reported involved a group of 8 nurses identified by their colleagues as exemplary. The major theme revealed in this study was that these exemplary nurses were also excellent role models in the clinical setting. This paper details approaches used by these nurses that made them excellent role models. Specifically, the themes of attending to the little things, making connections, maintaining a light-hearted attitude, modeling, and affirming others are presented. These themes are discussed within the framework of Watson [Watson, J., 1989. Human caring and suffering: a subjective model for health services. In: Watson, J., Taylor, R. (Eds.), They Shall Not Hurt: Human Suffering and Human Caring. Colorado University, Boulder, CO] "transpersonal caring" and [Bandura, A., 1997. Social Learning Theory. Prentice Hall, Englewood Cliffs, NJ] "Social Learning Theory." Particular emphasis in the discussion is on how positive role modeling by exemplary practitioners can contribute to the education of clinical nurses in the practice setting.

2006-01-01

This two-part article explores the process of role transition as it pertains to nurses moving from roles of caregivers to roles of case managers. Part 1 of the article presented a theoretical model that demonstrated the interplay of significant factors in the process of role transition and discussed how this model could be used to examine nurses' experience of this transition. Part 2 presents findings from a qualitative study involving interview and focus group data contributed by nurses who have made the transition from caregiver to case manager. Data point to specific tensions experienced by these nurses, which are associated with time-task orientation, interactions and relationships, business culture and objectives, and self-image and professional identity. Recommendations for preparing and supporting nurses through this role are also offered.

Role conflict: cause of burnout or energizer?

PubMed

Jones, M L

1993-03-01

A year-long study of public child welfare administrators examined the effects of role conflict on their attitudes and performance. Popular belief and some of the literature have suggested that burnout is inevitable for those confronted with role conflict. Other literature has proposed that it may instead be energizing to individuals and lead to greater personal and organizational effectiveness. This qualitative study found that individuals in the study had developed specific, effective skills for responding to role conflict. Although there was a public presentation of self that indicated they were under stress and in "impossible" situations, there was in fact an energizing effect resulting from the ongoing challenge of dealing with conflict.

1990-01-01

Although clinical nurse specialists (CNSs) have been in the Army Medical Department for more than 10 years, there are no reports in the literature regarding role implementation for them. In this study, a survey of all practicing CNSs in the Army Medical Department (AMEDD) and their supervisors was conducted with the purpose of defining their perceived role and the value placed on it by their supervisors. The results showed that the study population (n = 52) has implemented the role with all components (practice, education, consultation, administration, and research) considered important by them. Further, 85% of the CNSs report positive job satisfaction, and 67% believe they have reached role maturation. Their supervisors were equally or more positive about the importance of the role, and all (n = 26) felt it must be maintained despite budget constraints and nursing shortages. Findings were that CNSs experience role satisfaction, have achieved role maturation, and are valued by their supervisors within the AMEDD.

This study delves into the different roles that elementary science teachers play in the classroom to orchestrate science learning opportunities for students. Examining the classroom practices of three elementary science teachers in Singapore, we found that teachers shuttle between four key roles in enabling student learning in science. Teachers can play the role of (1) dispenser of knowledge (giver), (2) mentor of learning (advisor), (3) monitor of students' activities (police), and (4) partner in inquiry (colearner). These roles are dynamic, and while teachers show a preference for one of the four roles, factors such as the nature of the task, the types of students, as well as the availability of time and resources affect the role that teachers adopt. The roles that teachers play in the classroom have implications for the practice of science as inquiry in the classroom as well as the identities that teachers and students form in the science learning process.

The process of maternal role attainment over the first year.

Mercer, R T

1985-01-01

A study of the process of maternal role attainment in three age groups (15 to 19 years, 20 to 29 years, and 30 to 42 years) over the first year of motherhood found that the role attainment behaviors of feelings of love for the baby, gratification in the maternal role, observed maternal behavior, and self-reported ways of handling irritating child behaviors did not show a positive linear increase over the year. Behaviors peaked at 4 months postbirth, but declined at 8 months. Interview data suggested that the challenges of the infant's developmental behaviors at 8 and 12 months contributed to feelings of role incompetency. Although age groups functioned at different levels, their patterns of behaviors over the year did not vary, except for gratification in the role, indicating that the maternal role presented similar challenges for all women. There were no significant differences by maternal age in role strain or self-image as a mother over the year.

Ebolaviruses: New roles for old proteins.

PubMed

Cantoni, Diego; Rossman, Jeremy S

2018-05-01

In 2014, the world witnessed the largest Ebolavirus outbreak in recorded history. The subsequent humanitarian effort spurred extensive research, significantly enhancing our understanding of ebolavirus replication and pathogenicity. The main functions of each ebolavirus protein have been studied extensively since the discovery of the virus in 1976; however, the recent expansion of ebolavirus research has led to the discovery of new protein functions. These newly discovered roles are revealing new mechanisms of virus replication and pathogenicity, whilst enhancing our understanding of the broad functions of each ebolavirus viral protein (VP). Many of these new functions appear to be unrelated to the protein's primary function during virus replication. Such new functions range from bystander T-lymphocyte death caused by VP40-secreted exosomes to new roles for VP24 in viral particle formation. This review highlights the newly discovered roles of ebolavirus proteins in order to provide a more encompassing view of ebolavirus replication and pathogenicity.

Possible role of hemichannels in cancer

Schalper, Kurt A.; Carvajal-Hausdorf, Daniel; Oyarzo, Mauricio P.

2014-01-01

In humans, connexins (Cxs) and pannexins (Panxs) are the building blocks of hemichannels. These proteins are frequently altered in neoplastic cells and have traditionally been considered as tumor suppressors. Alteration of Cxs and Panxs in cancer cells can be due to genetic, epigenetic and post-transcriptional/post-translational events. Activated hemichannels mediate the diffusional membrane transport of ions and small signaling molecules. In the last decade hemichannels have been shown to participate in diverse cell processes including the modulation of cell proliferation and survival. However, their possible role in tumor growth and expansion remains largely unexplored. Herein, we hypothesize about the possible role of hemichannels in carcinogenesis and tumor progression. To support this theory, we summarize the evidence regarding the involvement of hemichannels in cell proliferation and migration, as well as their possible role in the anti-tumor immune responses. In addition, we discuss the evidence linking hemichannels with cancer in diverse models and comment on the current technical limitations for their study. PMID:25018732

Movement dynamics reflect a functional role for weak coupling and role structure in dyadic problem solving.

PubMed

Abney, Drew H; Paxton, Alexandra; Dale, Rick; Kello, Christopher T

2015-11-01

Successful interaction requires complex coordination of body movements. Previous research has suggested a functional role for coordination and especially synchronization (i.e., time-locked movement across individuals) in different types of human interaction contexts. Although such coordination has been shown to be nearly ubiquitous in human interaction, less is known about its function. One proposal is that synchrony supports and facilitates communication (Topics Cogn Sci 1:305-319, 2009). However, questions still remain about what the properties of coordination for optimizing communication might look like. In the present study, dyads worked together to construct towers from uncooked spaghetti and marshmallows. Using cross-recurrence quantification analysis, we found that dyads with loosely coupled gross body movements performed better, supporting recent work suggesting that simple synchrony may not be the key to effective performance (Riley et al. 2011). We also found evidence that leader-follower dynamics-when sensitive to the specific role structure of the interaction-impact task performance. We discuss our results with respect to the functional role of coordination in human interaction.

Antagonistic neural networks underlying differentiated leadership roles.

PubMed

Boyatzis, Richard E; Rochford, Kylie; Jack, Anthony I

2014-01-01

The emergence of two distinct leadership roles, the task leader and the socio-emotional leader, has been documented in the leadership literature since the 1950s. Recent research in neuroscience suggests that the division between task-oriented and socio-emotional-oriented roles derives from a fundamental feature of our neurobiology: an antagonistic relationship between two large-scale cortical networks - the task-positive network (TPN) and the default mode network (DMN). Neural activity in TPN tends to inhibit activity in the DMN, and vice versa. The TPN is important for problem solving, focusing of attention, making decisions, and control of action. The DMN plays a central role in emotional self-awareness, social cognition, and ethical decision making. It is also strongly linked to creativity and openness to new ideas. Because activation of the TPN tends to suppress activity in the DMN, an over-emphasis on task-oriented leadership may prove deleterious to social and emotional aspects of leadership. Similarly, an overemphasis on the DMN would result in difficulty focusing attention, making decisions, and solving known problems. In this paper, we will review major streams of theory and research on leadership roles in the context of recent findings from neuroscience and psychology. We conclude by suggesting that emerging research challenges the assumption that role differentiation is both natural and necessary, in particular when openness to new ideas, people, emotions, and ethical concerns are important to success.

Adaptive role switching promotes fairness in networked ultimatum game.

PubMed

Wu, Te; Fu, Feng; Zhang, Yanling; Wang, Long

2013-01-01

In recent years, mechanisms favoring fair split in the ultimatum game have attracted growing interests because of its practical implications for international bargains. In this game, two players are randomly assigned two different roles respectively to split an offer: the proposer suggests how to split and the responder decides whether or not to accept it. Only when both agree is the offer successfully split; otherwise both get nothing. It is of importance and interest to break the symmetry in role assignment especially when the game is repeatedly played in a heterogeneous population. Here we consider an adaptive role assignment: whenever the split fails, the two players switch their roles probabilistically. The results show that this simple feedback mechanism proves much more effective at promoting fairness than other alternatives (where, for example, the role assignment is based on the number of neighbors).

Sex-role orientation associations with college students' body-image preferences.

Sex roles dictate acceptable attitudes and preferences for men and women. Further, perception of ideal body type is one attitude and preference that may be associated with sex-role orientation. Therefore, the current study examined the association between sex-role orientation and men's and women's reports of their preferred body type and their views of others' preferred body type for men and women. Responses from 172 university students indicated sex-role associations with participants' personal body-type preferences and participants' perceptions of the body types others prefer. Analysis indicates that a more masculine sex-role orientation was associated with men's and women's perceptions of larger ideal body images. Results are discussed in terms of the association between sex-role orientation and possible susceptibility to societal standards of ideal body images.

Changes in social roles as predictors of changes in drinking behaviour.

Hajema, K J; Knibbe, R A

1998-11-01

To assess the possible effects of changes in marital status, employment status and having children at home on alcohol consumption and the frequency of heavy drinking. With role theory as a starting point it was expected that a shift into more social roles would decrease consumption and heavy drinking while the shift away from social roles would be associated with an increase in consumption and heavy drinking. Prospective cohort study. The province of Limburg, The Netherlands (1980-89). 1327 men and women aged 16-69 years at first measurement. Weekly consumption of standard units (10 g ethanol) of alcoholic beverages; frequency of drinking six units or more; self-reported social role. The acquisition of a spouse role and a parental role but not an employment role was associated with a decrease in consumption or heavy drinking. The loss of the spouse role among women was associated with an increase in heavy drinking. Otherwise, losing a role was not linked with a change in consumption and heavy drinking. Limited support was found for the expectation that role transitions influence drinking behaviour. Our study suggests that other theories must be sought to explain social differences in drinking behaviour.

2017-01-01

This multi-country study used role models to boost perceptions of entrepreneurial feasibility and desirability. The results of a structural equation model based on a sample comprising 426 individuals who were primarily from Austria, Finland and Greece revealed a significant positive influence on perceived entrepreneurial desirability and feasibility. These findings support the argument for embedding entrepreneurial role models in entrepreneurship education courses to promote entrepreneurial activities. This direction is not only relevant for the academic community but also essential for nascent entrepreneurs, policymakers and society at large.

Emotional boundary work in advanced fertility nursing roles.

PubMed

Allan, Helen; Barber, Debbie

2005-07-01

In this article we examine the nature of intimacy and knowing in the nurse-patient relationship in the context of advanced nursing roles in fertility care. We suggest that psychoanalytical approaches to emotions may contribute to an increased understanding of how emotions are managed in advanced nursing roles. These roles include nurses undertaking tasks that were formerly performed by doctors. Rather than limiting the potential for intimacy between nurses and fertility patients, we argue that such roles allow nurses to provide increased continuity of care. This facilitates the management of emotions where a feeling of closeness is created while at the same time maintaining a distance or safe boundary with which both nurses and patients are comfortable. We argue that this distanced or 'bounded' relationship can be understood as a defence against the anxiety of emotions raised in the nurse-fertility patient relationship.

Role of forensic pathologists in mass disasters.

2012-06-01

The forensic pathologist has always had a central role in the identification of the dead in every day practice, in accidents, and in disasters involving hundreds or thousands of victims. This role has changed in recent years, as advances in forensic odontology, genetics and anthropology have improved the chances of identifying victims beyond recognition. According to the Interpol DVI Guide, fingerprints, dental examination and DNA are the primary identifiers, and this has given new emphasis to the role of the forensic pathologist as the leader of a multidisciplinary team of experts in a disaster situation, based on his or her qualifications and the experience gained from doing the same work in the everyday situation of an institute of forensic medicine.

Multifaceted role of lipids in Mycobacterium leprae.

Mycobacterium leprae must adopt a metabolic strategy and undergo various metabolic alterations upon infection to survive inside the human body for years in a dormant state. A change in lipid homeostasis upon infection is highly pronounced in Mycobacterium leprae. Lipids play an essential role in the survival and pathogenesis of mycobacteria. Lipids are present in several forms and serve multiple roles from being a source of nutrition, providing rigidity, evading the host immune response to serving as virulence factors, etc. The synthesis and degradation of lipids is a highly regulated process and is the key to future drug designing and diagnosis for mycobacteria. In the current review, an account of the distinct roles served by lipids, the mechanism of their synthesis and degradation has been elucidated.

Androgens in pregnancy: roles in parturition

2014-01-01

BACKGROUND Understanding the physiology of pregnancy enables effective management of pregnancy complications that could otherwise be life threatening for both mother and fetus. A functional uterus (i) retains the fetus in utero during pregnancy without initiating stretch-induced contractions and (ii) is able to dilate the cervix and contract the myometrium at term to deliver the fetus. The onset of labour is associated with successful cervical remodelling and contraction of myometrium, arising from concomitant activation of uterine immune and endocrine systems. A large body of evidence suggests that actions of local steroid hormones may drive changes occurring in the uterine microenvironment at term. Although there have been a number of studies considering the potential role(s) played by progesterone and estrogen at the time of parturition, the bio-availability and effects of androgens during pregnancy have received less scrutiny. The aim of this review is to highlight potential roles of androgens in the biology of pregnancy and parturition. METHODS A review of published literature was performed to address (i) androgen concentrations, including biosynthesis and clearance, in maternal and fetal compartments throughout gestation, (ii) associations of androgen concentrations with adverse pregnancy outcomes, (iii) the role of androgens in the physiology of cervical remodelling and finally (iv) the role of androgens in the physiology of myometrial function including any impact on contractility. RESULTS Some, but not all, androgens increase throughout gestation in maternal circulation. The effects of this increase are not fully understood; however, evidence suggests that increased androgens might regulate key processes during pregnancy and parturition. For example, androgens are believed to be critical for cervical remodelling at term, in particular cervical ripening, via regulation of cervical collagen fibril organization. Additionally, a number of studies highlight

The nursing educator's role in e-learning: a literature review.

PubMed

Koch, Lee F

2014-11-01

e-Learning is becoming more commonplace in nursing and healthcare professional education. Research has shown that e-learning can be just as effective at helping students achieve cognitive learning objectives as traditional face-to-face courses, provided that certain quality criteria are met. However, the decentralized, asynchronous nature of e-learning precludes spontaneous, personal interaction between the instructor and the learner. In addition to this, learning objectives in nursing and other healthcare professions are not only within the cognitive, but also within the affective and psychomotor domains. This article seeks to answer the following question: How does e-learning transform the role of nurse educators? Narrative literature review. A comprehensive database search was conducted using the English and German key words "teacher," "educator," "role," "e-learning," and "nursing" to identify literature that examined the role of (nurse) educators in e-learning. The search strategy resulted in the inclusion of 40 sources. The majority of the literature is expert opinion and examines the educator's role in e-learning from a theoretical point of view (n=30). There is a paucity of empirical research pertaining directly to the educator's role (n=10). Only four sources deal specifically with the nurse educator's role. The literature agrees on the need for a new role definition in light of e-learning. This role is more complex than the educator's traditional role. The literature does not provide any indication of how the educator's role can be adapted to the specific needs of online nurse education. There is a need for more empirical research on this subject.

The impact of social roles on trait judgments: a critical reexamination.

PubMed

Bosak, Janine; Sczesny, Sabine; Eagly, Alice H

2012-04-01

Consistent with social role theory's assumption that the role behavior of men and women shapes gender stereotypes, earlier experiments have found that men's and women's occupancy of the same role eliminated gender-stereotypical judgments of greater agency and lower communion in men than women. The shifting standards model raises the question of whether a shift to within-sex standards in judgments of men and women in roles could have masked underlying gender stereotypes. To examine this possibility, two experiments obtained judgments of men and women using measures that do or do not restrain shifts to within-sex standards. This measure variation did not affect the social role pattern of smaller perceived sex differences in the presence of role information. These findings thus support the social role theory claim that designations of identical roles for subgroups of men and women eliminate or reduce perceived sex differences.

Work-role transition: from staff nurse to clinical nurse educator.

PubMed

Manning, Liz; Neville, Stephen

2009-07-01

This article presents the findings of a study describing Clinical Nurse Educators' experiences, as they recall their transition from staff nurse to the Clinical Nurse Educator role, within a New Zealand District Health Board. Nurse Educator roles influence clinical practice and professional development of nurses, and although designated as a senior role nationally, the complexities and size of the role are poorly understood. A qualitative descriptive methodology utilising transition theory as a conceptual framework underpinned the study. A sample of eight Clinical Nurse Educators from a New Zealand District Health Board were interviewed about their transition from experienced staff nurse to inexperienced senior nurse. Data were analysed using a general inductive approach. Participants found the Clinical Nurse Educator role was more complex than anticipated, with no preparation for the role and sub-optimal orientation periods being provided by the District Health Board. As a result, signs of stress were evident as the enormity of the role became apparent. Consequently, employers need to ensure that appropriate orientation programmes and mentorship are inherent in health care organisations.

Keeping experience at the bedside: the emergency consultant nurse role.

PubMed

Currie, Jane

The consultant nurse concept has not yet been transferred to the military setting. The motivation for developing the role in the NHS was to improve the quality of patient care by strengthening professional leadership and extending the clinical career ladder. The consultant nurse may be defined as an expert in their clinical field, possessing expert leadership and visionary skills. The role is based on four domains: expert practice, professional leadership, education and research. Typically, the emergency consultant nurse spends 50% of their time working clinically, thereby providing senior clinical expertise and adding value to the clinical role. In a military context the consultant nurse role could be perceived as the coming together of the senior command and administrative role and the clinical role. The military has the opportunity to develop a senior clinical emergency nurse role encompassing elements of the civilian consultant nurse model, which may strengthen leadership, provide a central resource of expertise and raise the profile of military nursing. This has the added potential to provide inspiration for junior nurses and retain experienced emergency nurses in the clinical arena.

Predicting Intentions to Read Suicide Awareness Stories. The Role of Depression and Characteristics of the Suicidal Role Model.

Research on factors that influence the intention to read suicide awareness material is lacking. To identify how social and state similarities between the featured protagonist of a suicide awareness story and the audience impact on the intent to read similar stories. Laboratory experiment with n = 104 students. Participants were randomly assigned to study groups. In the first group, the role model provided his personal story of crisis and was a student. In the second group, the content was identical but the model was socially dissimilar. The third group read about a topic unrelated to suicide. Depression, identification, and exposure intent were measured after the experiment. Conditional process analysis was carried out. In the group featuring a once-suicidal role model with high social similarity, depression in the audience increased the intention to read similar material in the future via identification with the role model; 82% of individuals wanted to read similar material in the future, but only 50% wanted to do so in the group featuring a dissimilar person. Exposure intention increases via identification when role model and audience characteristics align regarding social traits and the experience of depression. These factors are relevant when developing campaigns targeting individuals with stories of recovery.

  To explore the feasibility and acceptability of a clinical nurse leader (CNL) role to improve interdisciplinary collaboration (IC) within a fragmented acute-care microsystem.   Fragmented patient care is associated with preventable adverse healthcare outcomes. IC decreases fragmentation and improves patient care quality. The CNL role is theorized to provide the necessary leadership and competency skill base to impact IC at the optimal organizational level, the point of care where most healthcare decisions are made.   This study used a descriptive non-experimental design. CNL daily workflow was developed to target empirical determinants of IC. Descriptive data were collected from multiple stakeholders using an investigator-developed survey.   Findings indicate the integration of the role is feasible and acceptable to the microsystem healthcare team.   Preliminary evidence suggests the CNL role may be an effective intervention to facilitate IC. More research is needed to support the CNL role's association with microsystem IC.   The CNL role presents an innovative opportunity for clinical and administrative leadership to partner together to redesign a healthcare delivery system and improve patient care quality. © 2012 Blackwell Publishing Ltd.

This study describes the evolution of the clinical nurse leader (CNL(®) ) role and its utility in a tertiary care and community hospital. In the US, quality and safety metrics are being publically reported and healthcare organizations are just beginning to experience pay-for-performance and its impact. The American Association of the Colleges of Nursing (AACN) developed the role of the CNL to address the complexities and challenges of providing high-quality care in the current environment. Since 2007, a cohort of CNLs in practice has evaluated the effectiveness of the role with measures of clinical outcomes, financial savings and case studies. Having CNLs with a strategic perspective acting as facilitators and integrators of care has proven invaluable. Leadership support has been critical and commitment to maintaining the integrity of the role has ensured its success and sustainability. This role has established its value in risk assessment, strategic quality improvement, interdisciplinary collaboration and the implementation of evidence-based solutions. The flexibility and broad scope of this role allows for its use across practice settings and represents an exciting opportunity for nursing to drive quality of care to new levels while managing costs. © 2012 Blackwell Publishing Ltd.

Women and multiple roles: myths and reality.

PubMed

Barnett, Rosalind Chait

2004-01-01

Strong beliefs persist about the negative effects of maternal employment on women, their marriages, and their children, in spite of considerable systematic research indicating that, on average, employment has positive effects. The underlying assumption is that the roles of wife and mother are "natural" roles and are therefore performed without undue stress. In contrast, the role of employee is seen as "unnatural" and therefore highly demanding. These beliefs affect clinical practice, fostering a concern among mental health professionals about whether women can handle the demands of multiple roles without serious negative health consequences. It is therefore important to evaluate these beliefs in light of the empirical literature. Such an evaluation is especially critical at this particular time, when demographic trends suggest that the number of employed women with children is increasing, that paid employment will be a central component in most women's life experiences, and that as a society we are highly unlikely to return to the days of the "traditional" family. The need for careful scrutiny is underscored by the current political climate, in which there is much rhetoric implying that maternal employment "causes" many of our social ills--school dropouts, drug abuse, juvenile violence, and divorce.

Role of Bajo Women in Wakatobi Island

NASA Astrophysics Data System (ADS)

Fatirahwahidah; Mansur, Mansur

2018-05-01

This paper investigates the unique side of Bajo women at Pulau Pandai Besi in Wakatobi. Bajo women are able to take over their husband’s role. Bajo fishermen’s households present different conditions from the common fishermen community in which the man and woman can share roles in the family. Although naturally, men and women are created differently which leads to the role difference, the local wisdom of Bajo indicates that women are very dominant in their households. The husband only works in the sea to earn a fortune. Meanwhile, Bajo women, in addition to taking domestic roles such as cooking, taking care of children and cleaning the house, are also in control of the development and survival of their families when their husbands go sailing in the sea. This research is qualitative research. This research was conducted in Peka Besi region of Wakatobi in 2017. The data of this research were collected through observation and interview. The study reveals that women are the leaders and managers of their households. Regarding economic needs, Bajo women process and market the fish caught by their husbands, open a small shop of basic necessities, and sell a variety of traditional food.

The number of innovative roles in nursing and midwifery has expanded considerably; however, the evidence base for the introduction of these roles is limited. This study aimed to identify the managerial and developmental issues affecting those in innovative roles. A self-completion postal questionnaire was distributed to all innovative role holders in Northern Ireland, 450 responses were analysed. This survey was the second phase of a larger investigation into innovative roles in nursing and midwifery. The questionnaire that had been developed for the 'Exploring New Roles in Practice' project was adapted for use in this study. The explanatory letter sent to potential participants clearly detailed that informed consent was assumed on receipt of a completed questionnaire and gave contact details for the research team. The confidentiality and anonymity of responses were assured. Most participants (65%) stated that their innovative role had commenced since the year 2000. There was evidence of preparation for these roles including the development of job descriptions and protocols. Nevertheless, there were issues noted relating to resource allocation and replacement when the role holder was absent. The importance of role evaluation was highlighted, with some participants noting their role had not been assessed since its inception. Support provided by managers and colleagues was key to ensuring role effectiveness. Participants reported high levels of job satisfaction. Innovative role holders were identified by managers in their employing organization: therefore the research team could not verify that all existing innovative roles were included in the study. Innovative roles in private and voluntary sectors were not included. The evolution of innovative nursing and midwifery roles has been considerable worldwide and they engender job satisfaction to those occupants them. Results support international literature showing that adequate support, especially from administrators

Parkinson disease: a role for autophagy?

PubMed

Yang, Qian; Mao, Zixu

2010-08-01

Autophagy is a term used to describe the process by which lysosomes degrade intracellular components. Known originally as an adaptive response to nutrient deprivation, autophagy has now been recognized to play important roles in several human disorders including neurodegenerative diseases. Experimental results from genetic, cellular, and toxicological studies indicate that many of the etiological factors associated with Parkinson disease (PD) can perturb the autophagic process in various model systems. Thus, the emerging data support the view that dysregulation of autophagy may play a critical role in the pathogenic process of PD.

Can role models boost entrepreneurial attitudes?

PubMed Central

Fellnhofer, Katharina; Puumalainen, Kaisu

2017-01-01

This multi-country study used role models to boost perceptions of entrepreneurial feasibility and desirability. The results of a structural equation model based on a sample comprising 426 individuals who were primarily from Austria, Finland and Greece revealed a significant positive influence on perceived entrepreneurial desirability and feasibility. These findings support the argument for embedding entrepreneurial role models in entrepreneurship education courses to promote entrepreneurial activities. This direction is not only relevant for the academic community but also essential for nascent entrepreneurs, policymakers and society at large. PMID:28458611

On how role versatility boosts an STI.

Cortés, Andrés J

2017-12-19

The prevalence of the HIV-1 infection has decayed in the last decades in western heterosexual populations. However, among men who have sex with men (MSM) the prevalence is still high, despite intensive campaigns and treatment programs that keep infected men as undetectable (Beyrer et al. 2012). Promiscuity and condom fatigue (Adam et al. 2005), which are not unique to the MSM community, are making unprotected anal intercourse (UAI) more common and sexually transmitted infections (STIs) presumably harder to track. Yet, MSM communities are peculiar in the sense that men can adopt fixed (insertive or receptive) or versatile (both practices) roles. Some old theoretical work (Wiley & Herschkorn 1989, Van Druten et al. 1992, Trichopoulos et al. 1998) predicted that the transmission of HIV-1 would be enhanced in MSM populations engaged more in role versatility than in role segregation, in which fixed roles are predominantly adopted. These predictions were based on the assumption that the probability of acquisition from unprotected insertive anal (UIA) sex was neglectable. However, as later shown (Vittinghoff et al. 1999, Goodreau et al. 2005), this assumption is inappropriate and HIV-1 may still be acquired via UIA sex. Here I show through a stochastic model that the increase of the HIV-1 prevalence among MSM due to role versatility holds under a stronger assumption of bidirectional virus transmission.

Race differences in the relationship between role experiences and well-being.

PubMed

Marcussen, Kristen; Piatt, Liz

2005-07-01

Theory and research generally support the notion that social roles benefit subjective well-being. These conclusions, however, are largely based on studies examining Whites. Studies that have included Blacks have found race differences in the influence of social roles on well-being, yet most of these studies focus on role occupancy. With few exceptions, little attention has been paid to whether there are race differences in how individuals experience their roles, and the extent to which race differences in role experiences relate to differences in well-being. In this article we examine racial variation in the experience of work and family roles. We find that Blacks and Whites are similar in their experiences of role conflict and perceptions of role success and balance, but the association between these experiences and well-being varies, to some extent, by race and gender. The implications of these findings as well as suggestions for future research are discussed.

Clinical prioritisations of healthcare for the aged--professional roles.

Although fair distribution of healthcare services for older patients is an important challenge, qualitative research exploring clinicians' considerations in clinical prioritisation within this field is scarce. To explore how clinicians understand their professional role in clinical prioritisations in healthcare services for old patients. A semi-structured interview-guide was employed to interview 45 clinicians working with older patients. The interviews were analysed qualitatively using hermeneutical content analysis. 20 physicians and 25 nurses working in public hospitals and nursing homes in different parts of Norway. The clinicians struggle with not being able to attend to the comprehensive needs of older patients, and being unfaithful to professional ideals and expectations. There is a tendency towards lowering the standards and narrowing the role of the clinician. This is done in order to secure the vital needs of the patient, but is at the expense of good practice and holistic role modelling. Increased specialisation, advances and increase in medical interventions, economical incentives, organisational structures, and biomedical paradigms, may all contribute to a narrowing of the clinicians' role. Distributing healthcare services in a fair way is generally not described as integral to the clinicians' role in clinical prioritisations. If considerations of justice are not included in clinicians' role, it is likely that others will shape major parts of their roles and responsibilities in clinical prioritisations. Fair distribution of healthcare services for older patients is possible only if clinicians accept responsibility in these questions.

Automated Comparative Auditing of NCIT Genomic Roles Using NCBI

Cohen, Barry; Oren, Marc; Min, Hua; Perl, Yehoshua; Halper, Michael

2008-01-01

Biomedical research has identified many human genes and various knowledge about them. The National Cancer Institute Thesaurus (NCIT) represents such knowledge as concepts and roles (relationships). Due to the rapid advances in this field, it is to be expected that the NCIT’s Gene hierarchy will contain role errors. A comparative methodology to audit the Gene hierarchy with the use of the National Center for Biotechnology Information’s (NCBI’s) Entrez Gene database is presented. The two knowledge sources are accessed via a pair of Web crawlers to ensure up-to-date data. Our algorithms then compare the knowledge gathered from each, identify discrepancies that represent probable errors, and suggest corrective actions. The primary focus is on two kinds of gene-roles: (1) the chromosomal locations of genes, and (2) the biological processes in which genes plays a role. Regarding chromosomal locations, the discrepancies revealed are striking and systematic, suggesting a structurally common origin. In regard to the biological processes, difficulties arise because genes frequently play roles in multiple processes, and processes may have many designations (such as synonymous terms). Our algorithms make use of the roles defined in the NCIT Biological Process hierarchy to uncover many probable gene-role errors in the NCIT. These results show that automated comparative auditing is a promising technique that can identify a large number of probable errors and corrections for them in a terminological genomic knowledge repository, thus facilitating its overall maintenance.

HEALTH ISSUE: Research on the relationship between women's social roles and mental health has been equivocal. Although a greater number of roles often protect mental health, certain combinations can lead to strain. Our study explored the moderating affects of different role combinations on women's mental health by examining associations with socioeconomic status and differences in women's distress (depressive symptoms, personal stress (role strain) and chronic stress (role strain plus environmental stressors). KEY FINDINGS: Women with children, whether single or partnered, had a higher risk of personal stress. Distress, stress and chronic stress levels of mothers, regardless of employment, or marital status, are staggeringly high. Single, unemployed mothers were significantly more likely than all other groups to experience financial stress and food insecurity. For partnered mothers, rates of personal stress and chronic stress were significantly lower among unemployed partnered mothers. Married and partnered mothers reported better mental health than their single counterparts. Lone, unemployed mothers were twice as likely to report a high level of distress compared with other groups. Lone mothers, regardless of employment status, were more likely to report high personal and chronic stress. DATA GAPS AND RECOMMENDATIONS: National health surveys need to collect more data on the characteristics of women's work environment and their care giving responsibilities. Questions on household composition should include inter-generational households, same sex couples and multifamily arrangements. Data disaggregation by ethno-racial background would be helpful. Data should be collected on perceived quality of domestic and partnership roles and division of labours.

Role of Fat-Soluble Vitamins in Osteoarthritis Management.

PubMed

Zheng, Xiao-Yan; Liang, Jun; Li, Yu-Sheng; Tu, Min

2018-04-01

Osteoarthritis (OA) is a chronic degenerative joint disease, in which metabolic imbalance in bone is observed. The pathological mechanism of metabolic imbalance is not clear yet, but the nutritional factors, particularly the vitamins, might be intrinsic to the development and progression of OA. In this review article, we have explored databases such as PubMed, Scopus, and Google Scholar articles until the beginning of 2017 and reviewed the role of fat-soluble vitamins in pathological and therapeutic aspects of OA. Vitamin D plays an important role in the development and maintenance of the skeleton, as well as bone and cartilage metabolism, and its deficiency is implicated in the pathological process of OA. Vitamin E enhances chondrocyte growth and exhibits an anti-inflammatory activity, as well as plays an important role in the prevention of cartilage degeneration. In human OA cartilage, vitamin K deficiency produces abnormal growth plate calcification and inappropriate mineralization of cartilage. Thus, these fat-soluble vitamins play a key role in the pathophysiology of OA, and supplementation of these vitamins may provide innovative approaches for OA management. However, vitamin A has a different role, which is a regulator of cartilage and skeletal formation. When metabolite levels of vitamin A are elevated in synovial fluid, they appear to drive OA development. The role of inhibitors of vitamin A here remains unclear. More investigations are needed to examine the effects of fat-soluble vitamins on the various molecular pathways of OA, as well as to assess the efficacy and safety of their usage clinically.

Role-playing in the problem-based learning class.

PubMed

Chan, Zenobia C Y

2012-01-01

Learning and teaching have been conceptualized and executed in many styles, such as self-learning, peer learning, and interaction between the learner and mentor. Today, openness to alternative ideas and embracing innovative approaches in nursing education are encouraged in order to meet students' learning interests and needs, and to address ever-changing healthcare requests. Problem-based learning has been widely adopted in nursing education, with various positive effects on students' learning, such as motivated learning, team work, problem-solving skills and critical thinking. Role-plays have been demonstrated as an effective learning strategy that includes an active and experiential feature that facilitates students' autonomy in their health-related learning. However, there is a lack of discussion of whether and how role-play can be used in problem-based learning (PBL). This paper shows the development of a classroom-based innovation using role-play in the PBL class for higher diploma year-one nurse students (a total of 20 students, five per group). This paper consists of five sections: a) the literature on PBL and nurse education, and role-plays as the innovation; b) the PBL case scenario with the illustration of the two role-play scripts, c) student evaluation on role-play in the PBL class; d) discussions on both achievements and limitations of this innovation, and e) the conclusion. It is hoped that this paper will be an example to other nurse educators who are keen on exploring interactive and student-driven learning and teaching strategies in the PBL class.

2014-01-01

Forensic dentistry has become an integral part of forensic science over the past 100 years that utilizes dental or oro-facial findings to serve the judicial system. This has been due to the dedication of people like Gustafson's, Keiser-Nielson, and Suzuki for this field. They established the essential role which forensic dentistry plays mainly in the identification of human remains. The tooth has been used as weapons and under certain circumstances, may leave information about the identity of the biter. Dental professionals have a major role to play in keeping accurate dental records and providing all necessary information so that legal authorities may recognize mal practice, negligence, fraud or abuse, and identity of unknown individuals. This paper will try to summarize the various roles of dental experts in forensic medicine. PMID:25298709

PubMed search using the terms preconception, immunizations, epilepsy, diabetes, depression, tobacco, asthma, hypertension, anticoagulation, pharmacist, pregnancy, and current national guidelines. Preconception health has become recognized as an important public health focus to improve pregnancy outcomes. Pharmacists have a unique role as accessible health care providers to optimize preconception health by screening women for tobacco use, appropriate immunizations, and current medication use. Counseling patients on preconception risk factors and adequate folic acid supplementation as well as providing recommendations for safe and effective management of chronic conditions are also critical and within the scope of practice for pharmacists. Pharmacists play an important role in medication screening, chronic disease state management, and preconception planning to aid women in preparing for healthy pregnancies.

The role of pleiotrophin in bone repair.

Lamprou, Margarita; Kaspiris, Angelos; Panagiotopoulos, Elias; Giannoudis, Peter V; Papadimitriou, Evangelia

2014-12-01

Bone has an enormous capacity for growth, regeneration, and remodelling, largely due to induction of osteoblasts that are recruited to the site of bone formation. Although the pathways involved have not been fully elucidated, it is well accepted that the immediate environment of the cells is likely to play a role via cell–matrix interactions, mediated by several growth factors. Formation of new blood vessels is also significant and interdependent to bone formation, suggesting that enhancement of angiogenesis could be beneficial during the process of bone repair. Pleiotrophin (PTN), also called osteoblast-specific factor 1, is a heparin-binding angiogenic growth factor, with a well-defined and significant role in both physiological and pathological angiogenesis. In this review we summarise the existing evidence on the role of PTN in bone repair.

Scala Roles: Reusable Object Collaborations in a Library

NASA Astrophysics Data System (ADS)

Pradel, Michael; Odersky, Martin

Purely class-based implementations of object-oriented software are often inappropriate for reuse. In contrast, the notion of objects playing roles in a collaboration has been proven to be a valuable reuse abstraction. However, existing solutions to enable role-based programming tend to require vast extensions of the underlying programming language, and thus, are difficult to use in every day work. We present a programming technique, based on dynamic proxies, that allows to augment an object’s type at runtime while preserving strong static type safety. It enables role-based implementations that lead to more reuse and better separation of concerns.

Negotiating multiple roles: link teachers in clinical nursing practice.

PubMed

Ramage, Charlotte

2004-02-01

The background to this study was a concern about the teacher's role in clinical practice. Experience suggested that teachers believed that their role in practice was important but that there were significant forces which impeded their ability to move with ease between education and practice. A discrepancy between previous research findings and theoretical discussions, and the reality experienced by teachers, led to the adoption of grounded theory as a way of exploring uncertainties in the situation. Data were gathered over a period of 7 years and involved 28 in-depth interviews with nurses with a range of educational roles, employed in educational institutions and practice settings in inner city and provincial areas in the South of England. The data revealed four categories, 'gaining access', 'negotiating credibility', 'being effective' and the core category 'negotiating multiple roles'. The core category is addressed in this article. Experiences of moving from a position of clinical practitioner to link teacher involved: 'disassembling the self' through leaving behind old identities; 'reconstructing the self' through clarifying new ways of being; and, finally, 'realizing the self' through reciprocal interpersonal activity with students, educational and nursing colleagues. It is inevitable that an individual with a remit for change entering an established social group will experience difficulties in establishing their role. It is also clear that an individual who changes their role within a group to reflect behaviours not congruent with the primary activity in that setting will experience dimensions of social exclusion. Further work needs to address how educational roles can make a significant impact on the everyday lives of students and nurses working in practice. The findings of this study are as relevant for the new roles of practice educator, clinical facilitator and practice placement co-ordinator as they are for link teachers and lecturer practitioners

The influence of role models in undergraduate nurse education.

To explore the concept of role modelling in undergraduate nurse education and its effect on the personal and professional development of student nurses. Effective educative strategies are important for student nurses, who have to cope with learning in both clinical and university settings. Given the contemporary issues facing nurse education and practice in the United Kingdom (UK), it is timely and important to undertake pedagogical research into the concept of role modelling as an effective educative method. A descriptive narrative approach. Unstructured interviews were conducted with 14 current/recently discontinued students from Adult and Mental Health branches of nursing degree programmes in the north-west region of England, United Kingdom (UK). Data were thematically analysed. Students valued exposure to positive role models in clinical and university settings and viewed them as beneficial to their learning. Exposure to negative role models occurred, and this provided students with opportunities to consider the type of nurse they aspired to become. In some cases, students' exposure to perceived poor practice had an adverse effect on their learning and led to negative feelings about nursing work. Clinical staff might be perceived as more relevant role models than those in the university setting although there were still opportunities for academic staff to model professional behaviours. The study found that role modelling is an effective way to support learning and led to student satisfaction across both clinical and university settings. The findings support the use of role models in nurse education, and further research about conscious positive modelling of practice is required. Exploring the use of role models is important when examining ways in which the quality of nurse education might be developed. © 2017 John Wiley & Sons Ltd.

The Price of Anarchy in Network Creation Games Is (Mostly) Constant

NASA Astrophysics Data System (ADS)

Mihalák, Matúš; Schlegel, Jan Christoph

We study the price of anarchy and the structure of equilibria in network creation games. A network creation game (first defined and studied by Fabrikant et al. [4]) is played by n players {1,2,...,n}, each identified with a vertex of a graph (network), where the strategy of player i, i = 1,...,n, is to build some edges adjacent to i. The cost of building an edge is α> 0, a fixed parameter of the game. The goal of every player is to minimize its creation cost plus its usage cost. The creation cost of player i is α times the number of built edges. In the SumGame (the original variant of Fabrikant et al. [4]) the usage cost of player i is the sum of distances from i to every node of the resulting graph. In the MaxGame (variant defined and studied by Demaine et al. [3]) the usage cost is the eccentricity of i in the resulting graph of the game. In this paper we improve previously known bounds on the price of anarchy of the game (of both variants) for various ranges of α, and give new insights into the structure of equilibria for various values of α. The two main results of the paper show that for α > 273·n all equilibria in SumGame are trees and thus the price of anarchy is constant, and that for α> 129 all equilibria in MaxGame are trees and the price of anarchy is constant. For SumGame this (almost) answers one of the basic open problems in the field - is price of anarchy of the network creation game constant for all values of α? - in an affirmative way, up to a tiny range of α.

Professional role identity in shaping community nurses' reactions to nursing policy.

Elliott, Lawrie; Kennedy, Catriona; Raeside, Robert

2015-05-01

To establish the extent to which professional role identity shapes community nurses' reactions before the implementation of a policy that sought to introduce a generic role. Many countries seek to alter community nurse roles to address changes in population health and health workforce. We know little about the influences that might shape nurses' reaction to these policies before their implementation and our theoretical understanding is poorly developed at this point in the policy-making cycle. Self completed cross-sectional survey of 703 community nurses before the introduction of a generic Community Health Nurse role in Scotland. The minority (33%) supported the new role. The professional role identity of those who were supportive differed significantly from those who did not support the policy or were uncertain of it. It is possible that the new policy acted to increase the value of the professional role identity of those who were supportive and conversely devalued the professional role identity of those who were unsupportive or uncertain of it. Professional role identity should be considered by policy makers in any country seeking to introduce policies that aim to radically change the role of community nurses and that this is acknowledged at an early stage in the policy-making cycle. © 2013 The Authors.

Expanding roles for lipid droplets

PubMed Central

Welte, Michael A.

2015-01-01

Summary Lipid droplets are the intracellular sites for neutral lipid storage. They are critical for lipid metabolism and energy homeostasis, and their dysfunction has been linked to many diseases. Accumulating evidence suggests that the roles lipid droplets play in biology are significantly broader than previously anticipated. Lipid droplets are the source of molecules important in the nucleus: they can sequester transcription factors and chromatin components and generate the lipid ligands for certain nuclear receptors. Lipid droplets have also emerged as important nodes for fatty acid trafficking, both inside the cell and between cells. In immunity, new roles for droplets, not directly linked to lipid metabolism, have been uncovered, as assembly platforms for specific viruses and as reservoirs for proteins that fight intracellular pathogens. Until recently, knowledge about droplets in the nervous system has been minimal, but now there are multiple links between lipid droplets and neurodegeneration: Many candidate genes for Hereditary Spastic Paraplegia also have central roles in lipid-droplet formation and maintenance, and mitochondrial dysfunction in neurons can lead to transient accumulating of lipid droplets in neighboring glial cells, an event that may, in turn, contribute to neuronal damage. As the cell biology and biochemistry of lipid droplets are increasingly well understood, the next few years should yield many new mechanistic insights into these novel functions of lipid droplets.

Shapiro, Danielle

2014-03-01

Previous research suggests that stepparenting can be stressful, although the mechanisms that contribute to the experience of parenting stress in stepfamilies are less clear. This study examines gender, marital quality, and views about gendered family roles as correlates of parenting stress among 310 stepmothers, stepfathers, and biological mothers and fathers. Findings suggest that stepparents, and especially stepmothers, experience higher levels of parenting stress than biological parents. Findings also suggest that less traditional views about gendered family roles and higher dyadic adjustment are associated with lower parenting stress for stepparents, particularly in combination. Stepparents reporting both of these protective factors were indistinguishable in terms of parenting stress from biological parents. These findings indicate potential pathways to mitigate the stress associated with stepparenting. © 2014 FPI, Inc.

The Dying Role: Its Relevance to Improved Patient Care.

PubMed

Noyes, Russell; Clancy, John

2016-01-01

SOCIETY is failing to meet the obligation it has to its dying members. Persons with terminal illnesses suffer isolation and neglect in hospitals, receive overzealous treatment by physicians, and are kept in ignorance of their situation by families and medical personnel. Evidence for these statements has come from observers of the medical care system and from dying patients themselves (Kübler-Ross, 1969; Reynolds and Kalish, 1974; Sudnow, 1967). In the nineteenth century it was common for persons to die in the familiar environs of their homes, surrounded by grieving families from whom they parted in a meaningful manner (Blauner, 1966). Dying persons of today no longer fill a well-defined social role. Instead, the distinction between the roles of sick and dying persons has been lost and, in the resulting confusion, the care of dying people has suffered. The purpose of this article is to clarify the distinction between the dying and sick roles, identify the signs of existing role confusion, suggest ways in which this confusion may be corrected, and show how reestablishment of the dying role can result in improved care of dying people. The important part physicians play in defining sick and dying roles will be emphasized.

A ROle-Oriented Filtering (ROOF) approach for collaborative recommendation

NASA Astrophysics Data System (ADS)

Ghani, Imran; Jeong, Seung Ryul

2016-09-01

In collaborative filtering (CF) recommender systems, existing techniques frequently focus on determining similarities among users' historical interests. This generally refers to situations in which each user normally plays a single role and his/her taste remains consistent over the long term. However, we note that existing techniques have not been significantly employed in a role-oriented context. This is especially so in situations where users may change their roles over time or play multiple roles simultaneously, while still expecting to access relevant information resources accordingly. Such systems include enterprise architecture management systems, e-commerce sites or journal management systems. In scenarios involving existing techniques, each user needs to build up very different profiles (preferences and interests) based on multiple roles which change over time. Should this not occur to a satisfactory degree, their previous information will either be lost or not utilised at all. To limit the occurrence of such issues, we propose a ROle-Oriented Filtering (ROOF) approach focusing on the manner in which multiple user profiles are obtained and maintained over time. We conducted a number of experiments using an enterprise architecture management scenario. In so doing, we observed that the ROOF approach performs better in comparison with other existing collaborative filtering-based techniques.

Sex-Role Inconstancy, Biology, and Successful Aging: A Dialectical Model

This paper examines sex-role inconstancy from a life-span point of view. New environmental realities and an increasing life-span may make traditional sex roles less functional in old age. Evidence is presented for more successful aging in persons manifesting convergent sex-role behavior. (Author)

Nursing faculty roles in international service-learning projects.

The purpose of this article is to describe faculty roles related to the design and implementation of an international nursing service-learning project. The impetus for this project was the 2008 American Association of Colleges of Nursing (AACN) recommendations for using service-learning and immersion of students in diverse communities to improve nursing education in the area of cultural competency (American Association of Colleges of Nursing, 2008a). We define service-learning as a learning experience engaging students in meeting community needs in an international setting so as to offer a different perspective into community health practices and to promote cultural competency. Based on our experience with service-learning, we identified four faculty roles in developing these types of projects. We define these roles as initiator, collaborator, facilitator, and advocate. This article will discuss the application of these faculty roles in developing service-learning opportunities with students. Copyright © 2013 Elsevier Inc. All rights reserved.

The empirical evidence as regards the precise association between alcohol use and social roles, and these associations across genders and cultures is heterogeneous. The literature tends to focus on two central but conflicting theories. The first - classic role theory - assumes that a higher number of social roles is associated with a more structured life and thus fewer opportunities to drink heavily. The second - the multiple burden hypothesis - posits that the increasing complexity of multiple social roles leads to higher stress levels, and thus to increased alcohol use. Survey data on 25- to 54-year olds in ten western industrialised countries which participate in the GenACIS project were used to test whether holding the three main social roles - partnership, parenthood, and paid labour - had a more protective or a more detrimental association with problematic alcohol use than holding fewer roles. Age and education were included as possible confounders, while the outcome variables were risky single occasion drinking (RSOD) and heavy-volume drinking. For both genders and in almost all countries, the study found that those who had all three roles were least likely to drink heavily or engage in RSOD, thus supporting the assumptions of classic role theory. It also found that the protective effect of multiple roles was more consistent for RSOD. There were a few countries where a two-role model gave a better fit. Results for Germany (RSOD), Switzerland, and the US (heavy volume) indicate that the role of paid labour appears to be particularly relevant for risky alcohol use among women. Despite some variability in the association between paid labour and heavy drinking or RSOD among women, in almost all countries the greater the number of roles a person held, the lower their risk of this type of alcohol use was.
