Lantibiotics are ribosomally synthesized peptide antibiotics composed of an N-terminal leader peptide that promotes the core peptide's interaction with the post translational modification (PTM) enzymes. Following PTMs, mutacin 1140 is transported out of the cell and the leader peptide is cleaved to yield the antibacterial peptide. Mutacin 1140 leader peptide is structurally unique compared to other class I lantibiotic leader peptides. Herein, we further our understanding of the structural differences of mutacin 1140 leader peptide with regard to other class I leader peptides. We have determined that the length of the leader peptide is important for the biosynthesis of mutacin 1140. We have also determined that mutacin 1140 leader peptide contains a novel four amino acid motif compared to related lantibiotics. PTM enzyme recognition of the leader peptide appears to be evolutionarily distinct from related class I lantibiotics. Our study on mutacin 1140 leader peptide provides a basis for future studies aimed at understanding its interaction with the PTM enzymes. © 2014 The Authors.

Developing science-based communication guidance and positive-themed messages for suicide prevention are important priorities. Drawing on social learning and elaboration likelihood models, we designed and tested two positive-focused presentations by high school peer leaders delivered in the context of a suicide prevention program (Sources of Strength). Thirty-six classrooms in four schools (N = 706 students) were randomized to (1) peer leader modeling of healthy coping, (2) peer leader modeling plus audience involvement to identify trusted adults, or (3) control condition. Students' attitudes and norms were assessed by immediate post-only assessments. Exposure to either presentation enhanced positive coping attitudes and perceptions of adult support. Students who reported suicide ideation in the past 12 months benefited more than nonsuicidal students. Beyond modeling alone, audience involvement modestly enhanced expectations of adult support, congruent with the elaboration likelihood model. Positive peer modeling is a promising alternative to communications focused on negative consequences and directives and may enhance social-interpersonal factors linked to reduced suicidal behaviors. © 2015 The American Association of Suicidology.

2017-12-01

Full Text Available The power and importance of peer influence in educational settings has been well documented (Cuseo, 2010; Ender & Kay, 2001; Keup, 2010. In South Africa, research supports international trends that student involvement in peer-led activities contributes to student success and ultimate throughput (Layton & McKenna, 2015; Loots, 2009; Underhill & McDonald, 2010. A plethora of research exists attesting to the benefits for students who are the recipients of peer-led activities. In South Africa, however, knowledge gaps exist pertaining to a national perspective on the experiences and, to some extent, on the benefits of peer leadership activities for peer leaders themselves. The purpose of this study is to provide an initial national snapshot of the development and experiences of peer leaders at six South African institutions of higher education, using the International Survey of Peer Leaders (ISPL. The research design adopted was a non-probability purposive sampling technique, with a sample size of N=466. Data were analysed using descriptive analyses. Findings validate previous findings and provide a more comprehensive picture of the types of peer leadership positions held, the training and support peer leaders receive, levels of engagement, and the benefits of being involved in peer-led activities.

Class attendance, peer similarity, and academic performance in a large field study

2017-01-01

Identifying the factors that determine academic performance is an essential part of educational research. Existing research indicates that class attendance is a useful predictor of subsequent course achievements. The majority of the literature is, however, based on surveys and self-reports, methods which have well-known systematic biases that lead to limitations on conclusions and generalizability as well as being costly to implement. Here we propose a novel method for measuring class attendance that overcomes these limitations by using location and bluetooth data collected from smartphone sensors. Based on measured attendance data of nearly 1,000 undergraduate students, we demonstrate that early and consistent class attendance strongly correlates with academic performance. In addition, our novel dataset allows us to determine that attendance among social peers was substantially correlated (>0.5), suggesting either an important peer effect or homophily with respect to attendance.

A Latent Class Analysis of Early Adolescent Peer and Dating Violence: Associations With Symptoms of Depression and Anxiety.

Science.gov (United States)

Garthe, Rachel C; Sullivan, Terri N; Behrhorst, Kathryn L

2018-02-01

Violence within peer and dating contexts is prevalent among early adolescents. Youth may be victims and/or aggressors and be involved in violence across multiple contexts, resulting in negative outcomes. This study identified patterns of perpetration and victimization for peer and dating violence, using a latent class analysis (LCA), and examined how different patterns of engaging in or experiencing violence among early adolescents were associated with symptoms of depression and anxiety. Participants included a sample of 508 racially and ethnically diverse youth (51% male) who had dated in the past 3 months. Youth were in the seventh grade within 37 schools and were primarily from economically disadvantaged communities across four sites in the United States. LCA identified three classes: (a) a low involvement in violence class, (b) a peer aggression and peer victimization class, and (c) a peer and dating violence class. Youth involved with multiple forms of violence displayed significantly higher levels of depressive and anxious symptoms than those with low involvement in violence. Study findings revealed the importance of understanding how peer and dating violence co-occur, and how different patterns of aggression and victimization were related to internalizing symptoms. Prevention efforts should address the intersection of victimization and perpetration in peer and dating contexts in potentially reducing internalizing symptoms among early adolescents.

Improving health consciousness and life skills in young people through peer-leadership in Thailand.

Teerachote, C; Kessomboon, P; Rattanasiri, A; Koju, R

2013-01-01

Peer leadership is widely recognized as an effective approach to health promotion and empowerment among people of similar ages, especially the youth. Such programs build peer leaders who in turn help empower the youths in their groups to improve their health and life skills related to health. Most previous studies have focused on the effectiveness of such activities in target groups but have neglected to effectively address and explore the transformations in peer leaders themselves. This descriptive study aimed to investigate the level of social change and health consciousness among student peer leaders in three Youth health promotion programs in Thailand: Friend's Corner, Smart Consumer and Volunteer Minded Young Dentists, and to compare them with the general students. The study was conducted using a self-administered questionnaire, which was developed based on Tyree's Social Change Model of leadership, Gould's concept and Dutta-Bergman's concept. The study population comprised of 11th grade students (N=660) from Kalasin Province in Thailand, 320 of whom were peer leaders. The findings revealed that the peer leaders scored higher than non peer leaders in all domains. Among the peer leaders, it was found that Volunteer Minded Young Dentists group had the highest scores in "controversy with civility", "social change agent" characteristics, "holistic health perceptions" and "responsibility for one's own health" regarding health consciousness. The results of this study confirmed that the peer leadership approach can help young people to develop life skills through social transformation and increase health consciousness for better status of health in the community.

Peer Led Team Learning in Introductory Biology: Effects on Peer Leader Critical Thinking Skills

Science.gov (United States)

Snyder, Julia J.; Wiles, Jason R.

2015-01-01

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

Social adjustment of children with cerebral palsy in mainstream classes: peer perception.

Science.gov (United States)

Nadeau, Line; Tessier, Réjean

2006-05-01

The aim of this study was to describe the social experience of children with cerebral palsy (CP) in mainstream classes in Canada and compare it with that of their classmates without disability. The CP group included 25 females and 35 males (mean age 10 y 5 mo [SD 0.95], range 10 y 4 mo-10 y 10 mo) diagnosed as having hemiplegia (n=44) or diplegia (n=16) and classified as Level I on the Gross Motor Function Classification System (GMFCS). Fifty-seven comparison children, born at term and without any motor and/or sensory impairment, were recruited from the classes of the children with CP during a school visit (mean age 10 y 3 mo, [SD 1.0], range 10 y-10 y 6 mo). They were matched to children with CP for sex, age, parents' education level, and family income. Social adjustment measures (social status, reciprocated friendships, social isolation, aggression, sociability/leadership, and verbal and/or physical victimization) were obtained by conducting a class-wide sociometric interview (n=943) in the classes of the children with CP. Findings showed that children with CP (specifically females with CP and irrespective of their type of disability) had fewer reciprocated friendships, exhibited fewer sociable/leadership behaviours, and were more isolated and victimized by their peers than their classmates without a disability. This seems to suggest that females and males with CP are perceived differently from their peers in a mainstreaming context. The discussion addresses the issue of age- and sex-related differences and provides avenues of intervention relating to personal and environmental factors that could facilitate or interfere with the social experience of children with CP in a mainstream environment.

2018-04-28

The effectiveness of peer leaders in promoting health may depend on the position they occupy within their social networks. Using sociocentric (whole network) and behavioral data from the intervention arm of a cluster-randomized HIV prevention trial in Dar es Salaam, Tanzania, we used generalized linear models with standardized predictors to examine the association between heath leaders' baseline structural network position (i.e., in-degree and betweenness centrality) and their 12-month self-reported (1) confidence in educating network members about HIV and gender-based violence (GBV) and (2) number of past-week conversations about HIV and GBV. As in-degree centrality increased, leaders reported fewer HIV-related conversations. As betweenness centrality increased, leaders reported greater number of conversations about GBV. Network position was not significantly associated with confidence in discussing either topic. Our results suggest that peer leaders who occupy spaces between sub-groups of network members may be more effective in engaging their peers in sensitive or controversial topics like GBV than more popular peer leaders.

A Campus-Wide Investigation of Clicker Implementation: The Status of Peer Discussion in STEM Classes

Science.gov (United States)

Lewin, Justin D.; Vinson, Erin L.; Stetzer, MacKenzie R.; Smith, Michelle K.

2016-01-01

At the University of Maine, middle and high school teachers observed more than 250 university science, technology, engineering, and mathematics classes and collected information on the nature of instruction, including how clickers were being used. Comparisons of classes taught with (n = 80) and without (n = 184) clickers show that, while instructional behaviors differ, the use of clickers alone does not significantly impact the time instructors spend lecturing. One possible explanation stems from the observation of three distinct modes of clicker use: peer discussion, in which students had the opportunity to talk with one another during clicker questions; individual thinking, in which no peer discussion was observed; and alternative collaboration, in which students had time for discussion, but it was not paired with clicker questions. Investigation of these modes revealed differences in the range of behaviors, the amount of time instructors lecture, and how challenging the clicker questions were to answer. Because instructors can vary their instructional style from one clicker question to the next, we also explored differences in how individual instructors incorporated peer discussion during clicker questions. These findings provide new insights into the range of clicker implementation at a campus-wide level and how such findings can be used to inform targeted professional development for faculty.

An Agent-Based Model of Private Woodland Owner Management Behavior Using Social Interactions, Information Flow, and Peer-To-Peer Networks.

Directory of Open Access Journals (Sweden)

Emily Silver Huff

Full Text Available Privately owned woodlands are an important source of timber and ecosystem services in North America and worldwide. Impacts of management on these ecosystems and timber supply from these woodlands are difficult to estimate because complex behavioral theory informs the owner's management decisions. The decision-making environment consists of exogenous market factors, internal cognitive processes, and social interactions with fellow landowners, foresters, and other rural community members. This study seeks to understand how social interactions, information flow, and peer-to-peer networks influence timber harvesting behavior using an agent-based model. This theoretical model includes forested polygons in various states of 'harvest readiness' and three types of agents: forest landowners, foresters, and peer leaders (individuals trained in conservation who use peer-to-peer networking. Agent rules, interactions, and characteristics were parameterized with values from existing literature and an empirical survey of forest landowner attitudes, intentions, and demographics. The model demonstrates that as trust in foresters and peer leaders increases, the percentage of the forest that is harvested sustainably increases. Furthermore, peer leaders can serve to increase landowner trust in foresters. Model output and equations will inform forest policy and extension/outreach efforts. The model also serves as an important testing ground for new theories of landowner decision making and behavior.

Using VoiceThread to Promote Collaborative Learning in On-Line Clinical Nurse Leader Courses.

Science.gov (United States)

Fox, Ola H

The movement to advance the clinical nurse leader (CNL) as an innovative new role for meeting higher health care quality standards continues with CNL programs offered on-line at colleges and universities nationwide. Collaborative learning activities offer the opportunity for CNL students to gain experience in working together in small groups to negotiate and solve care process problems. The challenge for nurse educators is to provide collaborative learning activities in an asynchronous learning environment that can be considered isolating by default. This article reports on the experiences of 17 CNL students who used VoiceThread, a cloud-based tool that allowed them to communicate asynchronously with one another through voice comments for collaboration and sharing knowledge. Participants identified benefits and drawbacks to using VoiceThread for collaboration as compared to text-based discussion boards. Students reported that the ability to hear the voice of their peers and the instructor helped them feel like they were in a classroom communicating with "real" instructor and peers. Students indicated a preference for on-line classes that used VoiceThread discussions to on-line classes that used only text-based discussion boards. Copyright © 2016 Elsevier Inc.

We evaluated a peer leader-support program (PLSP) for diabetes self-management in China in terms of acceptability and feasibility; implementation; perceived advantages; disadvantages and barriers; reach and recruitment; effectiveness in terms of diabetes knowledge and clinical impacts; adoption; and sustainability. Within each of 3 cities in Anhui Province, 2 subcommunities were randomly assigned to usual care or PLSP. Peer leaders and staff of Community Health Service Centers (CHSCs) co-led biweekly educational meetings. Peer leaders also led biweekly discussion meetings, promoted regular care through the CHSCs, organized informal health promotion activities (eg, walking and tai chi groups), and provided informal individual support to participants through casual contact. Qualitative evaluations indicated acceptance of and positive responses to the program among patients, peer leaders, and CHSC staff. Implementation was successful in 2 of 3 subcommunities, the third failing for lack of staff resources. Reported advantages included peer support as a bridge between CHSCs and their patients. In 2 sites where the PLSP was implemented, analyses controlling for baseline differences and site showed significant benefits for PLSP relative to controls (P management. The PLSP was well accepted, feasible given sufficient administrative and staff resources, effective for those who participated, and generalizable to other sites and health problems. © 2015 Annals of Family Medicine, Inc.

Full Text Available Patricia A Rosenau, Rita F Lisella, Tracey L Clancy, Lorelli S NowellFaculty of Nursing, University of Calgary, Calgary, AB, CanadaBackground: The nursing workforce and nursing education demographic trends reinforce the urgency to cultivate future nursing leaders, educators, and mentors. The changing realities of health care environments, involving crowded student placements, overtaxed clinical mentors and preceptors, and inexperienced staff, hamper student learning and professional development. Peer mentoring has been used successfully in nursing education to enhance student engagement and the quality of the student learning experience. Although various terms like peer mentor have been used to describe the role of senior students facilitating junior student learning, the literature is silent about how peer mentoring fosters the development of future nursing education leaders.Objectives: The aim of this study was to understand how peer mentorship fosters the development of nursing education leadership in senior undergraduate nursing students enrolled in an elective undergraduate peer-mentoring credit course, Introductory Concepts in Nursing Education and Leadership Through Peer-Led Learning.Design and method: This phenomenological study explored the development of nursing education leadership in senior undergraduate students through the analysis of critical reflections of individual senior students and online discussions between triads of senior students teaching/learning across diverse junior-level theory and practice courses.Participants: Seventeen senior undergraduate nursing students enrolled in the elective course participated in the study.Results: From the critical reflections and online discussions, four themes emerged: "developing teaching philosophies and pedagogies", "learning teaching strategies", "supportive peer relationship", and "benefits of the peer mentorship program".Conclusion: The creation and promotion of peer leadership

Learning Gains from a Recurring "Teach and Question" Homework Assignment in a General Biology Course: Using Reciprocal Peer Tutoring Outside Class.

Providing students with one-on-one interaction with instructors is a big challenge in large courses. One solution is to have students interact with their peers during class. Reciprocal peer tutoring (RPT) is a more involved interaction that requires peers to alternate the roles of "teacher" and "student." Theoretically, advantages for peer tutoring include the verbalization and questioning of information and the scaffolded exploration of material through social and cognitive interaction. Studies on RPT vary in their execution, but most require elaborate planning and take up valuable class time. We tested the effectiveness of a "teach and question" (TQ) assignment that required student pairs to engage in RPT regularly outside class. A quasi-experimental design was implemented: one section of a general biology course completed TQ assignments, while another section completed a substitute assignment requiring individuals to review course material. The TQ section outperformed the other section by ∼6% on exams. Session recordings were coded to investigate correlation between TQ quality and student performance. Asking more questions was the characteristic that best predicted exam performance, and this was more predictive than most aspects of the course. We propose the TQ as an easy assignment to implement with large performance gains.

2002-03-01

Peer education has become a popular strategy for health promotion interventions with adolescents, but it has not been used widely in school-based nutrition education. This paper describes and reports on the feasibility of the peer leader component of a school-based nutrition intervention for young adolescents designed to increase fruit and vegetable intakes and lower fat foods. About 1,000 seventh-grade students in eight schools received the nutrition intervention. Of these, 272 were trained as peer leaders to assist the teacher in implementing the activities. Results from a multicomponent process evaluation based on peer leader and classroom student feedback, direct classroom observation, and teacher ratings and interviews are presented. Results show that peer-led nutrition education approaches in schools are feasible and have high acceptability among peer leaders, classroom students, and teachers.

Large amount of evidence supports the contribution of the Stanford Chronic Disease Self-Management Program (CDSMP) to a global chronic disease management strategy. However, many studies have suggested further exploring of the factors influencing acceptance and completion of participants in this program. This study aimed to describe and examine factors associated with acceptance and completion rates of the CDSMP among frequent users of health care services, and to highlight the experience of patients and peer leaders who facilitated the program. A descriptive design with mixed sequential data was used. Acceptance and completion rates were calculated and their relationship with patient characteristics was examined in regression analysis (n = 167). Interviews were conducted among patients who accepted (n = 11) and refused (n = 13) to participate and with the program coordinator. Focus groups were held with the seven peer leaders who facilitated the program. Data were analysed using thematic analysis. Of the 167 patients invited, 60 (36%) accepted to participate in the program. Group format was the most frequent reason to decline the invitation to participate. Twenty-eight participants (47%) completed the program. Participants who dropped out during the program raised different reasons such as poor health and too much heterogeneity among participants. Factors such as location, schedule, content, group composition and facilitation were considered as important elements contributing to the success of the program. The CDSMP could therefore be considered as a self-management support option for this vulnerable clientele, while taking measures to avoid too much heterogeneity among participants to improve completion rates. © The Author 2016.

While mental health peer support originated in its contemporary form in English-speaking countries, it is now spreading rapidly across the globe. This rapid growth presents two major challenges. The first pertains to "role integrity" and the second to the possible culture-bound nature of peer support; a concern which has attended the emergence of peer support in countries that have significantly different worldviews. Recognizing the growth of peer support and the resulting challenges, this report results from the convening of an international consortium of peer leaders from six continents (all but Antarctica). Following an environmental scan of the state of peer support globally, this group moved to develop consensus on a common, core set of guiding principles and values to ensure a robust future for the development of effective, culturally responsive forms of peer support. Key principles, values and practices considered essential to peer support are presented. Assuming that sufficient political and community support are generated, there can be considerable enthusiasm for the expansion of peer support around the globe. Peer leaders are encouraged, however, to develop and deliver peer support both with integrity to its founding values in a civil rights and social justice framework and with responsiveness to local cultural worldviews.

Creative benefits from well-connected leaders: leader social network ties as facilitators of employee radical creativity.

Science.gov (United States)

Venkataramani, Vijaya; Richter, Andreas W; Clarke, Ronald

2014-09-01

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

Full Text Available Aim: Research was conducted as a experimental study in order to determine the effect of menstrual health education conducted with peer education to adolescent girls in 6-8 classes on information and behaviors. Method: The study was made in Primary School of Regional Girl Boarding. Working group consisted of 202 students responded completely pre-test and post-test from 214 female students studying in this school in 2008-2009 academic year. Data were collected by Personal Information Form, Menstruation and Menstrual Health Information Form. The forms were implemented to all students before the start of peer education program. Then, a total of 24 students including two students from each class were chosen as a peer educator with simple random sampling method. Peer educators were given information about menstruation and menstrual health for 2 hours per week and a total of 6 hours during 3 weeks in line with the educational booklet. Peer educator were asked to share acquired this information with classmates in various environments. Forms used at the beginning of students were applied to students again 4 weeks after completion of peer education program. Results: The average score of the students' knowledge of menstruation and menstrual health increased significantly (p <0.05 after the peer education program. Also, a statistically significant increase has occurred in the behaviors of students’ washing their hands before the toilet during menstruation, lustrating from front to back with toilet paper, bathing in the form of shower during menstruation, using cotton underwear, changing frequently pads used and taking away the pads used by wrapping (p<0.05. Conclusion: It can be considered that the method of peer education is an effective method to increase knowledge of adolescent girls about menstruation and menstrual health and develop health behaviors.

Raising schooling quality in low-income countries is a pressing challenge. Substantial research has considered the impact of cutting class sizes on skills acquisition. Considerably less attention has been given to the extent to which peer effects, which refer to class composition, also may affect...... bias from omitted variables, the preferred IV results indicate considerable negative effects due to larger class sizes and larger numbers of overage-for-grade peers. The latter, driven by the highly prevalent practices of grade repetition and academic redshirting, should be considered an important...

I follow, therefore I lead: A longitudinal study of leader and follower identity and leadership in the marines.

Science.gov (United States)

Peters, Kim; Haslam, S Alexander

2018-05-22

It is acknowledged that identity plays an important role in a person's leadership development. To date, however, there has been little consideration of the possibility - suggested by the social identity perspective - that individuals who identify as followers may be especially likely to emerge as leaders. We test this possibility in a longitudinal sample of recruit commandos in the Royal Marines. Recruits rated their identification with leader and follower roles five times over the course of their 32-week training programme. Recruits' leadership and followership were evaluated by their commanders, and their leadership was assessed by their peers. Analysis indicated that while recruits who identified as leaders received higher leadership ratings from their commanders, recruits who identified - and were perceived - as followers emerged as leaders for their peers. These findings suggest that follower and leader identities underpin different aspects of leadership and that these are differentially recognized by others. © 2018 The British Psychological Society.

Objective Evaluate the acceptability, feasibility, and preliminary outcomes of a peer-mediated intervention to improve social competence of brain tumor survivors and classmates. Methods Twelve childhood brain tumor survivors and 217 classroom peers in intervention (n = 8) or comparison (n = 4) classrooms completed measures of social acceptance and reputation at two time points in the year. The intervention (5–8 sessions over 4–6 weeks) taught peer leaders skills for engaging classmates. Individual and classroom outcomes were analyzed with ANCOVA. Results Recruitment rates of families of brain tumor survivors (81%) and schools (100%) were adequate. Peer leaders reported satisfaction with the intervention. Preliminary outcome data trended toward some benefit in increasing the number of friend nominations for survivors of brain tumors but no changes in other peer-reported metrics. Preliminary results also suggested some positive effects on classroom levels of victimization and rejection. Conclusions A peer-mediated intervention was acceptable to families of brain tumor survivors and feasible to implement in schools. Findings warrant a larger trial to evaluate improvements for children with brain tumors and their peers. PMID:27355881

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

The aim of this study was to determine the validity of peer evaluation for team-based learning (TBL) classes in dental education in comparison with the term-end examination records and TBL class scores. Examination and TBL class records of 256 third- and fourth-year dental students in six fixed prosthodontics courses from 2013 to 2015 in one dental school in Japan were investigated. Results of the term-end examination during those courses, individual readiness assurance test (IRAT), group readiness assurance test (GRAT), group assignment projects (GAP), and peer evaluation of group members in TBL classes were collected. Significant positive correlations were found between all combinations of peer evaluation, IRAT, and term-end examination. Individual scores also showed a positive correlation with group score (total of GRAT and GAP). From the investigation of the correlations in the six courses, significant positive correlations between peer evaluation and individual score were found in four of the six courses. In this study, peer evaluation seemed to be a valid index for learning performance in TBL classes. To verify the effectiveness of peer evaluation, all students have to realize the significance of scoring the team member's performance. Clear criteria and detailed instruction for appropriate evaluation are also required.

Peer teaching is an effective tool to promote learning and retention of knowledge. By preparing to teach, students are encouraged to construct their own learning program, so that they can explain effectively to fellow learners. Peer teaching is introduced in present study to foster learning and pedagogical skills amongst first year medical under-graduates in physiology with a Hypothesis that teaching is linked to learning on part of the teacher. Non-randomized, Interventional study, with mixed methods design. Cases experienced peer teaching whereas controls underwent tutorials for four consecutive classes. Quantitative Evaluation was done through pre/post test score analysis for Class average normalized gain and tests of significance, difference in average score in surprise class test after one month and percentage of responses in closed ended items of feedback questionnaire. Qualitative Evaluation was done through categorization of open ended items and coding of reflective statements. The average pre and post test score was statistically significant within cases (p = 0.01) and controls (p = 0.023). The average post test scores was more for cases though not statistically significant. The class average normalized gain (g) for Tutorials was 49% and for peer teaching 53%. Surprise test had average scoring of 36 marks (out of 50) for controls and 41 marks for cases. Analysed section wise, the average score was better for Long answer question (LAQ) in cases. Section wise analysis suggested that through peer teaching, retention was better for descriptive answers as LAQ has better average score in cases. Feedback responses were predominantly positive for efficacy of peer teaching as a learning method. The reflective statements were sorted into reflection in action, reflection on action, claiming evidence, describing experience, and recognizing discrepancies. Teaching can stimulate further learning as it involves interplay of three processes: metacognitive awareness

A Peer-Support and Mindfulness Program to Improve the Mental Health of Medical Students.

Science.gov (United States)

Moir, Fiona; Henning, Marcus; Hassed, Craig; Moyes, Simon A; Elley, C Raina

2016-01-01

There is evidence that peer-support programs can improve mental health indices and help-seeking behavior among students in some secondary school and university settings and that mindfulness can improve mental health in medical students. Peer-led programs have not been formally assessed in a medical student population, where psychological issues exist and where it has been shown that students approach peers for help in preference to staff members or professional services. Medical students elected peer leaders who underwent training and then provided the intervention. The peer leaders provided support to students in the intervention group, as well as offering teaching in mindfulness meditation. An exploratory study was conducted with 2nd- and 3rd-year medical students at 1 medical school in New Zealand randomized into 2 groups. In addition to existing mental health resources, intervention participants received a program including peer support and peer-taught mindfulness practice. Study participants not offered the intervention participants could use existing mental health resources. Primary measures included depression (PHQ-9) and anxiety (GAD-7) scores. Secondary measures were quality of life, resilience (15-item resilience scale), academic self-concept, and motivation to learn, assessed at baseline and 6 months. Of the 402 students eligible, 275 (68%) participated and 232 (58%) completed the study. At baseline, 53% were female and mean age was 21 years (SD = 3)-PHQ-9 score (M = 5.2, SD = 3.7) and GAD-7 score (M = 4.5, SD = 3.4). Twelve peer leaders were elected. There was good participation in the intervention. One fourth of intervention students used the face-to-face peer support and more than 50% attended a peer social event and/or participated in the mindfulness program. Although improvements in mental health were seen in the intervention group, the difference between the intervention and nonintervention groups did not reach statistical significance. Although

The paper further aims to identify the leaders’ vulnerability and strength at work in the current situation of shortage of manpower and other resources in the health care sector. This is seen through the lens of self-determination theory.Methods: Qualitative interviews were conducted with nine nursing leaders in nursing homes and home-care services, which, in part, capture the municipal health care service in a time of reform.Results: The nursing leaders are highly independent regarding their role as leaders. They act with strength and power in their position as superiors for their own staff, but they lack support and feel left alone by their leader, the municipal health director. The relation between the nursing leaders and their superiors is characterized by controlling structures and lack of autonomy support. As a consequence, the nursing leaders’ relations with subordinates and particularly peers, contribute to satisfy their needs for competence and relatedness, and, to some extent, autonomy. However, this cannot substitute for the lack of support from the superior level.Conclusion: The paper maintains a need to increase the consciousness of the value of horizontal support and interaction with peers and subordinates for the municipal nursing leader. Also, the need for increased focus on “the missing link” upward between the municipal health director and the

The impact of contact on students' attitudes towards peers with disabilities.

This study aimed to understand the relationship between contact with peers with Special Educational Needs (SEN) and students' attitudes towards their peers with SEN, by examining the inter-group contact theory in regular and inclusive classes. A total of 463 students in 8th grade, with a mean age of 14.42 years, from 25 secondary school classes in Styria (Austria) completed a self-report questionnaire regarding their contact with peers with SEN and their attitudes towards peers with disabilities. Contact was indicated by nominations for joint activities and examined in inclusive and regular classes. The German short version of the Chedoke-McMaster Attitudes towards Children with Handicaps scale (CATCH; Schwab, 2015b; Rosenbaum et al., 1986) was used to measure students' attitudes towards peers with learning disabilities and emotional disorders. Students with SEN are less frequently nominated by their peers for joint activities, such as working together on a school project. Students from inclusive and regular classes did not differ in their attitudes towards peers with SEN. However, those students who nominated at least one peer with SEN for a joint activity had more positive attitudes towards peers with disabilities. Freely choosing contact with a peer with SEN was associated with more positive attitudes towards disability while simply attending the same class may have no effect or even a negative impact on students' attitudes.

We estimate peer effects in risk attitudes in a sample of high school students. Relative risk aversion is elicited from surveys administered at school. Identification of peer effects is based on parents not being able to choose the class within the school of their choice, and on the use of instrumental variables conditional on school-grade fixed effects. We find a significant and quantitatively large impact of peers' risk attitudes on a male individual's coefficient of risk aversion. Specifically, a one standard deviation increase in the group's coefficient of risk aversion increases an individual's risk aversion by 43%. Our findings shed light on the origin and stability of risk attitudes and, more generally, on the determinants of economic preferences. © 2014 Society for Risk Analysis.

Our study assessed the impact of the Students As LifeStyle Activists (SALSA program on SALSA peer leaders’ EBRBs, and their intentions regarding these behaviors. Methods We used a pre–post study design to assess changes in EBRBs and intentions of Year 10 secondary school students (15–16 year olds who volunteered to be peer leaders to deliver the SALSA program to Year 8 students (13–14 year olds. This research is part of a larger study conducted during 2014 and 2015 in 23 secondary schools in Sydney, Australia. We used an online questionnaire before and after program participation to assess Year 10 peer leaders’ fruit and vegetable intake, daily breakfast eating, sugar sweetened beverage (SSB intake, moderate-to-vigorous physical activity (MVPA participation and school-day recreational screen time behaviors and intentions regarding these EBRBs. Generalized estimating equations with a robust variance structure and exchangeable correlation structure were used to estimate the individual-level summary statistics and their 95% CIs, adjusted for clustering. We further assessed the effect of covariates on EBRB changes. Results There were significant increases in the proportion of Year 10 peer leaders (n = 415 who reported eating ≥2 serves fruit/day fruit from 54 to 63% (P < 0.01; eating ≥5 serves vegetables/day from 8 to 12% (P < 0.01; and drinking <1 cup/day of SSBs from 56 to 62% (P < 0.01.

Hojat, Mohammadreza; Michalec, Barret; Veloski, J Jon; Tykocinski, Mark L

2015-04-01

To test the hypotheses that medical students recognized by peers as the most positive social influencers would score (1) high on measures of engaging personality attributes that are conducive to relationship building (empathy, sociability, activity, self-esteem), and (2) low on disengaging personality attributes that are detrimental to interpersonal relationships (loneliness, neuroticism, aggression-hostility, impulsive sensation seeking). The study included 666 Jefferson Medical College students who graduated in 2011-2013. Students used a peer nomination instrument to identify classmates who had a positive influence on their professional and personal development. At matriculation, these students had completed a survey that included the Jefferson Scale of Empathy and Zuckerman-Kuhlman Personality Questionnaire short form and abridged versions of the Rosenberg Self-Esteem Scale and UCLA Loneliness Scale. In multivariate analyses of variance, the method of contrasted groups was used to compare the personality attributes of students nominated most frequently by their peers as positive influencers (top influencers [top 25% in their class distribution], n = 176) with those of students nominated least frequently (bottom influencers [bottom 25%], n = 171). The top influencers scored significantly higher on empathy, sociability, and activity and significantly lower on loneliness compared with the bottom influencers. However, the effect size estimates of the differences were moderate at best. The research hypotheses were partially confirmed. Positive social influencers appear to possess personality attributes conducive to relationship building, which is an important feature of effective leadership. The findings have implications for identifying and training potential leaders in medicine.

The Leader Ship Is Sinking: A Temporal Investigation of Narcissistic Leadership.

Ong, Chin Wei; Roberts, Ross; Arthur, Calum A; Woodman, Tim; Akehurst, Sally

2016-04-01

Individuals higher in narcissism have leader emergent tendencies. The characteristics of their personality suggest, however, that their leadership qualities will decrease over time as a function of group acquaintance. We present data from two studies that provide the first empirical support for this theoretical position within a transformational leadership framework. In Study 1 (N = 112), we tested narcissistic leadership qualities in groups of unacquainted individuals over a 12-week period. In Study 2 (N = 152), we adopted the same protocol with groups of acquainted individuals. In Study 1, narcissism was positively associated with peer-rated leadership during initial group formation but not later. In Study 2, narcissism was not significantly associated with peer-rated leadership during initial group formation and was negatively associated with peer-rated leadership later. In Study 1, transformational leadership mediated the relationship between narcissism and leadership initially but not later on. In Study 2, transformational leadership failed to mediate the relationship between narcissism and leadership throughout the study. Despite enjoying a honeymoon period of leadership, the appeal and attractiveness of the narcissistic leader rapidly wane. This decline is explained in part by their changing transformational leadership qualities. © 2014 Wiley Periodicals, Inc.

Multiple-baseline, quasi-experimental design with video recorded engagement observations during conventional and revised education classes; visual and statistical analysis of difference in positive engagement responses observed in classes using each approach. 81 patients (72% male, 73% white, mean age 36 SD 15.6) admitted for SCI/D inpatient rehabilitation in a non-profit rehabilitation hospital, who attended one or more of 33 care self-management education classes that were video recorded. All study activities were approved by the host facility institutional review board. Conventional nurse-led self-management classes were replaced with revised peer-led classes incorporating approaches to promote transformative learning. Revised classes were introduced across three subject areas in a step-wise fashion over 15 weeks. Positive engagement responses (asking questions, participating in discussion, gesturing, raising hand, or otherwise noting approval) were documented from video recordings of 14 conventional and 19 revised education classes. Significantly higher average (per patient per class) positive engagement responses were observed in the revised compared to conventional classes (p=0.008). Redesigning SCI inpatient rehabilitation care self-management classes to promote transformative learning increased patient engagement. Additional research is needed to examine longer term outcomes and replicability in other settings.

Physician leaders in obstetrics and gynecology find themselves in complex power relationships with administrative subordinates, administrative peers, and administrative superiors. The ethical dimensions of these power relationships have not been examined previously. The authors draw on the work of 3 major historic figures (John Gregory, Thomas Hobbes, and Friedrich Hoffmann) to identify for the first time 3 major types of power relationships and organizational cultures. Gregorian power relationships and organizational cultures are characterized by shared fiduciary responsibility that advances the core mission of a health care organization. Hobbesian power relationships and organizational cultures are characterized by relentless self-interest in a zero-sum game. Hoffmannian power relationships and organizational cultures are characterized by enlightened self-interest in a win-win game. The authors analyze the ethical dimensions of power relationships of physician leaders with subordinates, peers, and superiors and of organizational cultures. The authors support transformational leadership toward Gregorian power relationships and organizational cultures, using, when necessary, Hoffmannian power relationships and organizational cultures as a way station.

HOW DOES PEER PRESSURE AFFECT EDUCATIONAL INVESTMENTS?

Science.gov (United States)

Bursztyn, Leonardo; Jensen, Robert

When effort is observable to peers, students may try to avoid social penalties by conforming to prevailing norms. To test this hypothesis, we first consider a natural experiment that introduced a performance leaderboard into computer-based high school courses. The result was a 24 percent performance decline. The decline appears to be driven by a desire to avoid the leaderboard; top performing students prior to the change, those most at risk of appearing on the leaderboard, had a 40 percent performance decline, while poor performing students improved slightly. We next consider a field experiment that offered students complimentary access to an online SAT preparatory course. Sign-up forms differed randomly across students only in whether they said the decision would be kept private from classmates. In nonhonors classes, sign-up was 11 percentage points lower when decisions were public rather than private. Honors class sign-up was unaffected. For students taking honors and nonhonors classes, the response depended on which peers they were with at the time of the offer, and thus to whom their decision would be revealed. When offered the course in a nonhonors class (where peer sign-up rates are low), they were 15 percentage points less likely to sign up if the decision was public. But when offered the course in an honors class (where peer sign-up rates are high), they were 8 percentage points more likely to sign up if the decision was public. Thus, students are highly responsive to their peers are the prevailing norm when they make decisions.

Developing Leaders: Implementation of a Peer Advising Program for a Public Health Sciences Undergraduate Program

Full Text Available Peer advising is an integral part of our undergraduate advising system in the Public Health Sciences major at the University of Massachusetts Amherst. The program was developed in 2009 to address the advising needs of a rapidly growing major that went from 25 to over 530 majors between 2007 and 2014. Each year, 9-12 top performing upper-level students are chosen through an intensive application process. A major goal of the program is to provide curriculum and career guidance to students in the major and empower students in their academic and professional pursuits. The year-long program involves several components, including: staffing the drop-in advising center, attending training seminars, developing and presenting workshops for students, meeting prospective students and families, evaluating ways to improve the program, and collaborating on self-directed projects. The peer advisors also provide program staff insight into the needs and perspectives of students in the major. In turn, peer advisors gain valuable leadership and communication skills, and learn strategies for improving student success. The Peer Advising Program builds community and fosters personal and professional development for the peer advisors. In this paper, we will discuss the undergraduate peer advising model, the benefits and challenges of the program, and lessons learned. Several methods were used to understand the perceived benefits and challenges of the program and experiences of students who utilized the Peer Advising Center. The data for this evaluation were drawn from three sources: 1 archival records from the Peer Advising Center; 2 feedback from peer advisors who completed the year-long internship; and 3 a survey of students who utilized the Peer Advising Center. Results of this preliminary evaluation indicate that peer advisors gain valuable skills that they can carry into their professional world. The program is also a way to engage students in building community

Gender inequality is at the core of the HIV patterns that are evident in sub-Saharan Africa. Gender-based violence (GBV) and lack of economic opportunity are important structural determinants of HIV risk. We piloted a microfinance and health promotion intervention among social networks of primarily young men in Dar es Salaam. Twenty-two individuals participated in the microfinance component and 30 peer leaders were recruited and trained in the peer health leadership component. We collected and analysed observational data from trainings, monitoring data on loan repayment, and reports of peer conversations to assess the feasibility and acceptability of the intervention. Eighteen of the loan recipients (82%) paid back their loans, and of these 15 (83%) received a second, larger loan. Among the loan defaulters, one died, one had chronic health problems, and two disappeared, one of whom was imprisoned for theft. The majority of conversations reported by peer health leaders focused on condoms, sexual partner selection, and HIV testing. Few peer leaders reported conversations about GBV. We demonstrated the feasibility and acceptability of this innovative HIV and GBV prevention intervention. The lessons learned from this pilot have informed the implementation of a cluster-randomised trial of the microfinance and peer health leadership intervention.

To evaluate a prenatal breast-feeding class developed and facilitated by peer Breast-feeding Buddies. Non-equivalent control group quasi-experimental study comparing participants of the peer-led class (PLC) to those attending an established hospital-based breast-feeding nurse-led class (NLC). A brief questionnaire was completed immediately prior to the class, and telephone interviews were conducted approximately one week following the class, and one and six months post partum. 54 expectant mothers who registered for the community PLC and 55 expectant mothers who registered for the NLC. Breast-feeding intentions were measured at all time-points. Class evaluations, breast-feeding experiences, and breast-feeding support were measured at all post-class interviews. Both classes were considered worthwhile, but the PLC class was rated as more helpful and participants appreciated learning from the peers' personal experiences. Mothers taught by peers were more likely to access peer breast-feeding support. PLC participants initially decreased their prenatal breast-feeding duration intentions but had significantly stronger intentions to continue breast feeding at six months than did NLC mothers. A peer-led prenatal breast-feeding class is as effective as a traditional model of breast-feeding education and is a valuable tool to promote and support successful breast feeding. RECOMMENDATIONS FOR PRACTICE: Peer-led breast-feeding classes should be provided to enhance the accessibility of breast-feeding education and support for expectant mothers.

Formal faculty development programs for simulation educators are costly and time-consuming. Peer coaching integrated into the teaching flow can enhance an educator's debriefing skills. We provide a practical guide for the who, what, when, where, why, and how of peer coaching for debriefing in simulation-based education. Peer coaching offers advantages such as psychological safety and team building, and it can benefit both the educator who is receiving feedback and the coach who is providing it. A feedback form for effective peer coaching includes the following: (1) psychological safety, (2) framework, (3) method/strategy, (4) content, (5) learner centeredness, (6) co-facilitation, (7) time management, (8) difficult situations, (9) debriefing adjuncts, and (10) individual style and experience. Institutional backing of peer coaching programs can facilitate implementation and sustainability. Program leaders should communicate the need and benefits, establish program goals, and provide assessment tools, training, structure, and evaluation to optimize chances of success.

How Peer Pressure Shapes Consensus, Leadership, and Innovations in Social Groups

Estrada, Ernesto; Vargas-Estrada, Eusebio

2013-10-01

What is the effect of the combined direct and indirect social influences--peer pressure (PP)--on a social group's collective decisions? We present a model that captures PP as a function of the socio-cultural distance between individuals in a social group. Using this model and empirical data from 15 real-world social networks we found that the PP level determines how fast a social group reaches consensus. More importantly, the levels of PP determine the leaders who can achieve full control of their social groups. PP can overcome barriers imposed upon a consensus by the existence of tightly connected communities with local leaders or the existence of leaders with poor cohesiveness of opinions. A moderate level of PP is also necessary to explain the rate at which innovations diffuse through a variety of social groups.

2015-09-01

This pilot study investigated the feasibility, acceptability, and effectiveness of a peer-led dissonance-based eating disorders (ED) prevention/risk factor reduction program with high school girls. Ninth grade girls (n = 50) received the peer-led program within the school curriculum. A quasi-experimental design was used to assess changes in ED risk factors preintervention and postintervention compared with waitlist control. Participants were followed through 3-month follow-up. Peer-leader adherence to an intervention manual tailored for this age group was high. The intervention was rated as highly acceptable, with a large proportion of participants reporting that they enjoyed the program and learned and applied new information. Intervention participants exhibited significantly greater pre-post reductions in a majority of risk-factor outcomes compared to waitlist controls. When groups were combined to assess program effects over time there were significant pre-post reductions in a majority of outcomes that were sustained through 3-month follow-up. This pilot study provides tentative support for the effectiveness of using peer leaders to implement an empirically supported ED risk factor reduction program in a high school setting. Additional research is needed to replicate results in larger, better-controlled trials with longer follow-up. © 2015 Wiley Periodicals, Inc.

People with lived experience of mental illness have become leaders of an influential movement to help the mental health system embrace the notion of whole health and wellness in the areas of advocacy, policy, and care delivery. Wellness-oriented peer approaches delivered by peer-support whole-health specialists and wellness coaches can play an important role in integrated care models. This column examines the wellness definitions and peer models and some specific benefits and tensions between the peer-oriented wellness approach and the medical model. These models can work in unison to improve health and wellness among people with mental and substance use disorders.

Improving Scientific Writing in Undergraduate Geosciences Degrees Through Peer Review

Science.gov (United States)

Day, E. A.; Collins, G. S.; Craig, L.

2016-12-01

In the British educational system, students specialise early. Often geoscience undergraduates have not taken a class that requires extended writing since they were sixteen years old. This can make it difficult for students to develop the written skills necessary for a geoscience degree, which often has assessments in the form of essays and reports. To improve both the writing and editing skills of our undergraduates we have introduced a peer review system, in which seniors review the work of first year students. At Imperial College London we set written coursework in every year of the degree. Communication is taught and assessed in many courses. There are two major modules with substantial written components that bookend the undergraduate degree at Imperial; the freshmen all write an assessed essay, while all seniors take 'Science Communication', a course that aims to prepare them for a range of possible careers. In the 2015-16 academic year we linked these courses by introducing a modified form of peer marking and instruction. Seniors had to complete reviews of draft first year essays for credit in Science Communication. These reviews are completed for the department 'journal' and introduce the first and fourth years to the nature of peer review. Seniors learn how to critically, but kindly, evaluate the work of other students, and are also prepared for potentially submitting their senior theses to journals. Reviews were managed by volunteer seniors, who acted as associate editors. They allocated anonymous reviewers and wrote decision letters, which were sent to the freshmen before their final assessed essay submission. Ultimately the fourth year reviews were formally assessed and graded by members of staff, as were the revised and resubmitted first year essays. Feedback for both courses has improved since the introduction of student reviews of essays. The markers of the freshman essay have also commented on the improvement in the standard of the writing and a

Peer Instruction in introductory physics: A method to bring about positive changes in students’ attitudes and beliefs

Directory of Open Access Journals (Sweden)

Ping Zhang

2017-01-01

Full Text Available This paper analyzes pre-post matched gains in the epistemological views of science students taking the introductory physics course at Beijing Normal University (BNU in China. In this study we examined the attitudes and beliefs of science majors (n=441 in four classes, one taught using traditional (lecture teaching methods, and the other three taught with Peer Instruction (PI. In two of the PI classes, student peer groups were constantly changing throughout the semester, while in the other PI class student groups remained fixed for the duration of the semester. The results of the pre- and post-test using the Colorado Learning Attitudes about Science Survey showed that students in traditional lecture settings became significantly more novicelike in their beliefs about physics and learning physics over the course of a semester, a result consistent with what was reported in the literature. However, all three of the classes taught using the PI method improved student attitudes and beliefs about physics and learning physics. In the PI class with fixed peer groups, students exhibited a greater positive shift in attitudes and beliefs than in the other PI class with changing peer groups. The study also looked at gender differences in student learning attitudes. Gender results revealed that female science majors in the PI classes achieved a greater positive shift in attitudes and beliefs after instruction than did male students.

This process study is a companion to a randomized evaluation of a school-based, peer-led comprehensive sexual health education program, Teen Prevention Education Program (Teen PEP), in which 11th- and 12th-grade students are trained by school health educators to conduct informative workshops with ninth-grade peers in schools in North Carolina. The process study was designed to understand youth participants' perspectives on the program in order to gain insight into program effectiveness. This is a mixed-methods study in 7 schools, with online surveys (N = 88) and 8 focus groups with peer educators (N = 116), end-of-program surveys (N = 1122), 8 focus groups with ninth-grade workshop participants (N = 89), and observations of the Teen PEP class and workshops during the semester of implementation in each school, 2012-2014. Both peer educators and ninth graders perceived benefits of participating in Teen PEP across a range of domains, including intentions, skills, and knowledge and that the peer education modality was important in their valuation of the experience. Our findings suggest that the peer-led comprehensive sexual health education approach embodied in Teen PEP can be an important educational mechanism for teaching students information and skills to promote sexual health. © 2017, American School Health Association.

This article analyzes how the behaviors of leaders and peers affect the performance and well-being of military women. Locating our analysis within the conceptual model in this issue, we summarize the empirical literature and make practice and policy recommendations. We synthesize results about unit integration, such as research on the conditions for successful integration of previously excluded groups and on the relationship between cohesion and performance. We apply lessons learned from the history of diversity integration in military and civilian organizations, analyzing the treatment of military personnel by race, gender, and sexual orientation. The opening of ground combat specialties and units to women is the latest step in personnel policy changes broadening the recruitment base. We analyze research on gender integration in contemporary armed forces, focusing on positive and negative effects on women of leader and peer behaviors. We discuss conditions for successfully integrating women and those that tend to lead to failure. We analyze military women's family issues, including the effects of deployments and how leaders and peers can help ameliorate problems-or exacerbate them with inappropriate or unsupportive behavior.

The purpose of the present study was to assess the effect of peer education in type 2 diabetes patients with emotional disorders on the metabolic index and psychological status. Educators use psychological scales to screen type 2 diabetes patients with emotional disorders. Participants were divided into usual and peer education groups. Both groups received usual diabetes education. Peer leaders were recruited to provide support with the peer education group for 6 months. The metabolic index, diabetes knowledge, self-management, diabetes-related distress, emotional status and quality of life were compared at the end of the study. A total of 127 patients participated in the study. There were 20 peer leaders engaged in the study as volunteers for peer education. All participants completed the study and fulfilled the scales. Improvements in the peer education group were significant compared with the usual education group with respect to anxiety (49.0 ± 9.65 vs 54.0 ± 8.48), depression (51.3 ± 7.97 vs 55.8 ± 7.52), diabetes knowledge (18.8 ± 2.46 vs 16.3 ± 2.08), distress (2.67 ± 0.55 vs 3.02 ± 0.56), self-management (66.5 ± 4.26 vs 62.4 ± 5.88) and quality of life (-1.98 ± 0.82 vs -2.50 ± 0.71), whereas no significant difference existed with respect to the metabolic index. Peer education, providing more attention to diabetes patients with emotional disorders, is a preferred model for delivering care.

Full Text Available Politics in democracy and dictatorship is markedly different; democracy and dictatorship are also associated with distinct policy outcomes. Do political regimes also select different leaders, i.e., do democratic leaders have distinct personal backgrounds to those of their peers in dictatorships, do they tend to hold different prior careers and posts while climbing the “greasy pole” of politics? The aim of this paper is to introduce the new data on leaders’ careers in democracy and dictatorship and compare their personal background, experience in politics, careers and significant posts prior to their tenure, and details about their time in office, inter alia. In general, democratic leaders differ from nondemocratic ones in terms of their educational, social and career background. The paper also finds significant differences among leaders in different nondemocratic regimes, and suggests possible venues for further research.

This raises the question of whether lead users and opinion leaders are positioned similarly in social networks, which we addressed using a sample of 23 school classes consisting of 537 children....... Research among children is very scarce in this particular domain. Our statistical analyses based on hierarchical linear modeling reveal two general results: First, lead users among children appear to possess a variety of links between clusters. Second, opinion leaders are locally positioned within clusters...

Influence of religious leaders in the health-disease process

Elton Lima Macêdo

2017-02-01

Full Text Available Introduction: Religion has helped the lower classes to raise the perspective of "divine justice" in the struggle for survival by allowing their believers to seek, in their practices, under the influence of religious leaders, the main guidelines to alleviate the suffering from the health-disease process. Objective: Unveil the limits and potentialities of religious leaders' influence on the health-disease process. Materials and Methods: Exploratory-type research, with a qualitative approach, based methodologically on the Historical Dialectical Materialism. For the data analysis, one used the discourse analysis technique proposed by Fiorin. Results: From the empirical universe, two analytical categories emerged: (1. Limits and possibilities of religious influence in relation to the health-disease process; 2. Vulnerabilities of the Unified Health System and the complementarity of religion: Interfaces of the health-disease process in postmodernity, in which religious practices, institutions and leaders express positively health care in the face of the disease process. However, the religious leader's power relations over the community and religious fanaticism make the search for religion to have a negative influence on people's health-disease process. Conclusion: Religious leaders encourage the complementarity between religion and medicine only at times when their believers need medium and high-complexity assistance, showing little attention to the preventive aspects of self-care, which reinforces the need to invest in new studies in the area.

Peer Effects and Youth Smoking in the European Global Youth Tobacco Survey

Nikaj Silda

2017-09-01

Full Text Available This paper investigates the effect of peer smoking on individual smoking among youths in 10 countries that participated in the European Global Youth Tobacco Survey (GYTS. I control for endogeneity in school selection and unobserved school-level characteristics through the use of school fixed-effects. I use instrumental variables to address the simultaneity in peer and individual behaviours. Identification arises by comparing students in different classes within the same school. On average, an increase in the share of classmates who smoke by 10 percentage points increases the probability that an individual in that class will smoke by 3 to 6.9 percentage points. The results imply that any policy intervention such as anti-smoking messages, smoking bans, or higher cigarette prices will be even more cost-effective because of the social multiplier effect of peers – policies affecting some individuals in a group will generate spillovers to others through the peer effect.

Trust in direct leaders and top leaders: A trickle-up model.

Science.gov (United States)

Fulmer, C Ashley; Ostroff, Cheri

2017-04-01

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

Impact of supplemental instruction leader on the success of supplemental instruction model

Science.gov (United States)

Mahabaduge, Hasitha; Haslam, Jeanne

Supplemental instruction utilizes peer-assisted study sessions to provide review sessions on course material and an opportunity to discuss and work out problems. The impact of supplemental instruction on student performance is well researched and used in a large number of universities around the world due to its proven success. However, the impact of the student leader who plays a significant role in this model is rarely discussed in the literature. We present a case study on the impact of student leader on the success of supplemental instruction model. This case study was done for an Introductory Physics course correlating student performance and the supplemental instruction sessions they attended. Further analysis revealed that the academic performance and work ethics of the student leader has a significant impact on the success of the supplemental instruction model. Important factors to consider when selecting a student leader, the challenges and possible remedies will also be discussed.

Szeles, Heather M.

2015-01-01

Objective: The purpose of this mixed method, exploratory study was to measure the impact of a peer coaching program on the measured emotional intelligence (EI) of a group of student nurse leaders. Methods Participation in the study was offered to nurses in the Student Ambassador program. Students who consented received instruction on EI and its importance in leadership. Participants then took a preintervention EI test (The Mayer-Salovey-Caruso EI Test, version 2 [MSCEIT]) to obtain a baseline EI ability score. Students then participated in a series of peer coaching sessions across a semester. Participants then completed a postintervention MSCEIT test, and also a qualitative survey. Results: The analysis of the paired sample t-test showed that there was not a statistically significant difference in the total group EI scores from pre to posttest, t (8) = 0.036 >0.05; however, 80% of participants reported perceived changes in EI ability due to the intervention and 90% reported that peer coaching was beneficial to their leadership development. Conclusions: This study contributes to the body of EI literature and research on nursing education and leadership development. PMID:27981099

Leaders of neuronal cultures in a quorum percolation model

Directory of Open Access Journals (Sweden)

Jean-Pierre Eckmann

2010-09-01

Full Text Available We present a theoretical framework using quorum-percolation for describing the initiation of activity in a neural culture. The cultures are modeled as random graphs, whose nodes are neurons with $kin$ inputs and $kout$ outputs, and whose input degrees $kin=k$ obey given distribution functions $p_k$. We examine the firing activity of the population of neurons according to their input degree ($k$ classes and calculate for each class its firing probability $Phi_k(t$ as a function of $t$. The probability of a node to fire is found to be determined by its in-degree $k$, and the first-to-fire neurons are those that have a high $k$. A small minority of high-$k$ classes may be called ``Leaders,'' as they form an inter-connected subnetwork that consistently fires much before the rest of the culture. Once initiated, the activity spreads from the Leaders to the less connected majority of the culture. We then use the distribution of in-degree of the Leaders to study the growth rate of the number of neurons active in a burst, which was experimentally measured to be initially exponential. We find that this kind of growth rate is best described by a population that has an in-degree distribution that is a Gaussian centered around $k=75$ with width $sigma=31$ for the majority of the neurons, but also has a power law tail with exponent $-2$ for ten percent of the population. Neurons in the tail may have as many as $k=4,700$ inputs. We explore and discuss the correspondence between the degree distribution and a dynamic neuronal threshold, showing that from the functional point of view, structure and elementary dynamics are interchangeable. We discuss possible geometric origins of this distribution, and comment on the importance of size, or of having a large number of neurons, in the culture.

Response switching and self-efficacy in Peer Instruction classrooms

Miller, Kelly; Schell, Julie; Ho, Andrew; Lukoff, Brian; Mazur, Eric

2015-06-01

Peer Instruction, a well-known student-centered teaching method, engages students during class through structured, frequent questioning and is often facilitated by classroom response systems. The central feature of any Peer Instruction class is a conceptual question designed to help resolve student misconceptions about subject matter. We provide students two opportunities to answer each question—once after a round of individual reflection and then again after a discussion round with a peer. The second round provides students the choice to "switch" their original response to a different answer. The percentage of right answers typically increases after peer discussion: most students who answer incorrectly in the individual round switch to the correct answer after the peer discussion. However, for any given question there are also students who switch their initially right answer to a wrong answer and students who switch their initially wrong answer to a different wrong answer. In this study, we analyze response switching over one semester of an introductory electricity and magnetism course taught using Peer Instruction at Harvard University. Two key features emerge from our analysis: First, response switching correlates with academic self-efficacy. Students with low self-efficacy switch their responses more than students with high self-efficacy. Second, switching also correlates with the difficulty of the question; students switch to incorrect responses more often when the question is difficult. These findings indicate that instructors may need to provide greater support for difficult questions, such as supplying cues during lectures, increasing times for discussions, or ensuring effective pairing (such as having a student with one right answer in the pair). Additionally, the connection between response switching and self-efficacy motivates interventions to increase student self-efficacy at the beginning of the semester by helping students develop early mastery or

Women are underrepresented in science, technology, engineering, and mathematics (STEM) disciplines. Evidence suggests the microclimate of the classroom is an important factor influencing female course grades and interest, which encourages retention of women in STEM fields. Here, we test whether the gender composition of small (8-9 person) learning groups impacts course performance, sense of social belonging, and intragroup peer evaluations of intellectual contributions. Across two undergraduate active learning courses in introductory biology, we manipulated the classroom microclimate by varying the gender ratios of learning groups, ranging from 0% female to 100% female. We found that as the percent of women in groups increased, so did overall course performance for all students, regardless of gender. Additionally, women assigned higher peer- evaluations in groups with more women than groups with less women. Our work demonstrates an added benefit of the retention of women in STEM: increased performance for all, and positive peer perceptions for women.

Mastering the leader role : how individuals in leader roles increase leader role efficacy and trust in subordinates, (re)construct leader identities, and attempt to craft leader roles that fit

Sanfilippo, Fred; Powell, Deborah; Folberg, Robert; Tykocinski, Mark

2018-01-01

The 2017 Association of Pathology Chairs Annual Meeting included a session for department chairs and other department leaders on "how to deal with deans and academic medical center leadership." The session was focused on discussing ways to foster positive relationships with university, medical school, and health system leaders, and productively address issues and opportunities with them. Presentations and a panel discussion were provided by 4 former pathology chairs who subsequently have served as medical deans and in other leadership positions including university provost, medical center CEO, and health system board chair. There was a strong consensus among the participants on how best to deal with superiors about problems, conflicts, and requests for additional resources and authority. The importance of teamwork and accountability in developing a constructive and collaborative relationship with leaders and peers was discussed in detail. Effectiveness in communication, negotiation, and departmental advocacy were highlighted as important skills. As limited resources and increased regulations have become growing problems for universities and health systems, internal stress and competition have increased. In this rapidly changing environment, advice on how chairs can interact most productively with institutional leaders is becoming increasingly important.

Pharmacy leader development over time was analyzed using the seven action logics. As part of an ongoing leadership seminar series, students were required to select a visionary pharmacy leader and conduct a structured interview to evaluate pharmacy leaders' action logics. A standardized questionnaire comprising 13 questions was created by the class. Questions addressed leadership qualities during the leaders' early years, education years, and work years. Transcripts were then coded by two separate trained investigators based on the leader's stage of life to provide a score for each action logic individually over time. Kappa coefficient was used to evaluate interrater agreement. A total of 14 leaders were interviewed. All leaders were currently employed and had won national awards for their contributions to pharmacy practice. Overall, there was 82% agreement between the two evaluators' scores for the various characteristics. Action logics changed based on the leaders' life stage. Using aggregate data from all leader interviews, a progression from lower-order action logics (opportunist, diplomat, expert) to higher-order action logics (strategist, alchemist) was found. Ten leaders (71%) were diplomats during their early years. Six leaders (43%) were experts during their education years, and 4 (29%) were strategists or alchemists. During the third life stage analyzed (the work years), 6 leaders (43%) were strategists, and 2 were alchemists. During their work years, all leaders had a percentage of their answers coded as alchemist (range, 5-22%). Throughout their professional careers, pharmacy leaders continually develop skills through formal education and mentorship that follow action logics.

2017-12-01

Full Text Available This study examines the effectiveness of flipped classrooms in chemistry, and identifies relationships as a major factor impacting the success of flipped instruction methods. Examination of student interview data reveals factors that affect the development of peer-peer, peer-peer leader, and peer-expert relationships in first-year general chemistry and second-year organic chemistry flipped classrooms. Success was measured in terms of student perceptions of the effectiveness of the instruction, as well as student academic development. Furthermore, analysis of research participant interviews reveals that academic reading circles, open-response multiple-attempt group quizzes, and peer leaders are important elements of a text-centric flipped approach at a small-classroom, commuter-campus university. Student reflections and classroom observations provide further support for these conclusions. Cet étude examine l’efficacité des salles de classe inversées en chimie et identifie la création de liens en tant que facteur important qui affecte la réussite des méthodes d’instruction inversée.

Public health leadership development programs are widely employed to strengthen leaders and leadership networks and ultimately agencies and systems. The year-long National Public Health Leadership Institute's (PHLI) goals are to develop the capacity of individual leaders and networks of leaders so that both can lead improvement in public health systems, infrastructure, and population health. To evaluate the impact of PHLI on individual graduates using data collected from the first 15 cohorts. Between 1992 and 2006, PHLI graduated 806 senior leaders from governmental agencies, academia, health care, associations, nonprofit organizations, foundations, and other organizations. Of 646 graduates located, 393 (61%) responded to a survey, for an overall response rate of 49% (393/806). PHLI has included retreats; readings, conference calls, and webinars; assessments, feedback, and coaching; and action learning projects, in which graduates apply concepts to a work challenge aided by peers and a coach. A survey of all graduates and interviews of 34 graduates and one other key informant. PHLI improved graduates' understanding, skills, and self-awareness, strengthened many graduates' connections to a network of leaders, and significantly increased graduates' voluntary leadership activities at local, state, and national levels (P supportive peers and ideas, and bolstered confidence and interest in taking on leadership work. Nearly all graduates remained in public health. Some partially attributed to PHLI their promotions into more senior positions. Leadership development programs can strengthen and sustain their impact by cultivating sustained "communities of practice" that provide ongoing support for skill development and innovative practice. Sponsors can fruitfully view leadership development as a long-term investment in individuals and networks within organizations or fields of practice.

Pragmatic, consensus-based minimum standards and structured interview to guide the selection and development of cancer support group leaders: a protocol paper.

2017-06-30

Across the globe, peer support groups have emerged as a community-led approach to accessing support and connecting with others with cancer experiences. Little is known about qualities required to lead a peer support group or how to determine suitability for the role. Organisations providing assistance to cancer support groups and their leaders are currently operating independently, without a standard national framework or published guidelines. This protocol describes the methods that will be used to generate pragmatic consensus-based minimum standards and an accessible structured interview with user manual to guide the selection and development of cancer support group leaders. We will: (A) identify and collate peer-reviewed literature that describes qualities of support group leaders through a systematic review; (B) content analyse eligible documents for information relevant to requisite knowledge, skills and attributes of group leaders generally and specifically to cancer support groups; (C) use an online reactive Delphi method with an interdisciplinary panel of experts to produce a clear, suitable, relevant and appropriate structured interview comprising a set of agreed questions with behaviourally anchored rating scales; (D) produce a user manual to facilitate standard delivery of the structured interview; (E) pilot the structured interview to improve clinical utility; and (F) field test the structured interview to develop a rational scoring model and provide a summary of existing group leader qualities. The study is approved by the Department Human Ethics Advisory Group of The University of Melbourne. The study is based on voluntary participation and informed written consent, with participants able to withdraw at any time. The results will be disseminated at research conferences and peer review journals. Presentations and free access to the developed structured interview and user manual will be available to cancer agencies. © Article author(s) (or their

Observer-based leader-following tracking control under both fixed and switching topologies

This paper studies the tracking problem for a class of leader-follower multi-agent systems moving on the plane using observer-based cooperative control strategies. In our set-up, only a subset of the followers can obtain some relative information on the leader. We assume that the control input of the leader is not known to any of the followers while the system matrix is broadcast to all the followers. To track such a leader, an observer-based decentralized feedback controller is designed for each follower and detailed analysis for the convergence is presented for both fixed and switching interaction topologies between agents with the method of common Lyapunov function. We can also generalize the result to the higher dimension case for fixed topology and some special system matrices of the leader for switching topology.

2015-01-01

Strategic planning and thinking skills are essential for today's nurse leaders. Doctor of nursing practice (DNP) programs provide an opportunity for developing effective nurse strategists. A well-designed strategy course can stimulate intellectual growth at all levels of Bloom's Taxonomy. Discussion forums in online education provide new opportunities for rich interaction among peers en route to development of well-informed strategic plans. An interprofessional perspective adds a rich and vital aspect to doctoral nursing education and it serves to inform strategic plan development. A roadmap for teaching strategic planning to current and future nursing leaders will guide the integration of essential content into DNP programs.

Gender Differences in Resistance to Schooling: The Role of Dynamic Peer-Influence and Selection Processes.

Science.gov (United States)

Geven, Sara; O Jonsson, Jan; van Tubergen, Frank

2017-12-01

Boys engage in notably higher levels of resistance to schooling than girls. While scholars argue that peer processes contribute to this gender gap, this claim has not been tested with longitudinal quantitative data. This study fills this lacuna by examining the role of dynamic peer-selection and influence processes in the gender gap in resistance to schooling (i.e., arguing with teachers, skipping class, not putting effort into school, receiving punishments at school, and coming late to class) with two-wave panel data. We expect that, compared to girls, boys are more exposed and more responsive to peers who exhibit resistant behavior. We estimate hybrid models on 5448 students from 251 school classes in Sweden (14-15 years, 49% boys), and stochastic actor-based models (SIENA) on a subsample of these data (2480 students in 98 classes; 49% boys). We find that boys are more exposed to resistant friends than girls, and that adolescents are influenced by the resistant behavior of friends. These peer processes do not contribute to a widening of the gender gap in resistance to schooling, yet they contribute somewhat to the persistence of the initial gender gap. Boys are not more responsive to the resistant behavior of friends than girls. Instead, girls are influenced more by the resistant behavior of lower status friends than boys. This explains to some extent why boys increase their resistance to schooling more over time. All in all, peer-influence and selection processes seem to play a minor role in gender differences in resistance to schooling. These findings nuance under investigated claims that have been made in the literature.

What makes a leader?

Science.gov (United States)

Goleman, D

1999-01-01

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

Schwab, Susanne

2015-01-01

Positive peer relationships play a significant role in the development of students. They are beneficial for learning and psychological outcomes. This article draws upon an important distinction between the four main themes of social participation (friendships, interactions, peer acceptance and self-perception of social participation) and examines these aspects in inclusive and regular classes. Especially, differences in social participation of students with and without special educational needs (SEN) in inclusive classes and between students without SEN in inclusive and regular classes are examined. In this study, data from 1115 pupils in primary and secondary schools in Austria were analysed, of which 129 were diagnosed as having SEN. The results showed that in inclusive classes, students with SEN had lower scores on all four subthemes of social participation (friendships, interactions, peer acceptance and self-perception of social integration) than students without SEN. Regarding students without SEN, friendships and peer acceptance were significantly higher in inclusive classes than in regular classes. Differences were neither found for gender, nor between primary and secondary school students. Copyright © 2015 Elsevier Ltd. All rights reserved.

Full Text Available More currently literature reviews suggests the use of authentic assessment, which aims to involve students to be more responsible with their learning. This article reports the findings of a descriptive study on student teachers’ perception on the use of self and peer assessment to give evaluation on planning the lesson and teaching performance in Reflective Teaching Class. There were 100 samples taken randomly from 234 students in a survey using questionnaire and 15 students participating in the focus group discussion (FGD. The finding from the questionnaire shows that they had a very positive perception toward the use of self and peer assessment. Additionally, from the FGD, they conveyed by practicing doing self assessment, they could learn to see self performance deeply, strengths and weaknesses. From peer-assessment, they could learn collaboratively from feedback given by peers how to make a better lesson plan and perform a more effective teaching. Hence, self and peer assessment is considered beneficial for preparing the real teaching practicum and future career development. However, there are some problems challenged them, such as feeling subjectivity in assessing both self or peers, embarrassed and less confidence, and time constraints to make evaluation and reflection in the classroom

Peer mentored teams to support undergraduate group work in higher education

Science.gov (United States)

Cinderey, Lynn Elizabeth

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

To do so, we employed multiwave methodology to examine the differential impact of leaders' chronic collective, relational, and individual identities on the frequency and consistency of their subsequent transformational, consideration, and abusive behaviors over a 3-week period. We also examined the relative importance of these leadership behaviors for predicting perceived leader effectiveness as rated by subordinates and peers. Results indicated that leaders' collective and individual identities were uniquely related to transformational and abusive behaviors, respectively. We also observed a significant collective by individual identity interaction, such that abusive behaviors were most frequent when a strong individual identity was paired with a weak collective identity. Frequency of transformational behaviors accounted for the largest proportion of variance in perceived leader effectiveness, followed by frequency of abusive behaviors and consistency of transformational behaviors. We discuss the implications of these findings for leadership theory and development. (c) 2012 APA, all rights reserved.

2014-01-01

The present study investigated the impact of a manualized high school transition program, the Peer Group Connection (PGC) program, on the graduation rate at a low-income, Mid-Atlantic high school. The program utilized twelfth grade student peer leaders to create a supportive environment for incoming ninth grade students. Results of a randomized control trial demonstrated that male students who participated in the program during ninth grade were significantly more likely to graduate from high school within four years than male students in the control group (81% versus 63%). Findings suggest that peers can be effective in delivering a school-based, social emotional learning intervention and that it is possible to intervene in the ninth grade to influence the probability of high school graduation.

Hidden Advantages and Disadvantages of Social Class.

Three studies conducted among fifth and sixth graders examined how school contexts disrupt the achievement of working-class students by staging unfair comparison with their advantaged middle-class peers. In regular classrooms, differences in performance among students are usually showcased in a way that does not acknowledge the advantage (i.e., higher cultural capital) experienced by middle-class students, whose upbringing affords them more familiarity with the academic culture than their working-class peers have. Results of Study 1 revealed that rendering differences in performance visible in the classroom by having students raise their hands was enough to undermine the achievement of working-class students. In Studies 2 and 3, we manipulated students' familiarity with an arbitrary standard as a proxy for social class. Our results suggest that classroom settings that make differences in performance visible undermine the achievement of the students who are less familiar with academic culture. In Study 3, we showed that being aware of the advantage in familiarity with a task restores the performance of the students who have less familiarity with the task.

Adolescent and young adult binge drinking is strongly associated with perceived social norms and the drinking behavior that occurs within peer networks. The extent to which an individual is influenced by the behavior of others may depend upon that individual's resistance to peer influence (RPI). Students in their first semester of college (N=1323; 54.7% female, 57% White, 15.1% Hispanic) reported on their own binge drinking, and the perceived binge drinking of up to 10 important peers in the first-year class. Using network autocorrelation models, we investigated cross-sectional relationships between participant's binge drinking frequency and the perceived and actual binge drinking frequency of important peers. We then tested the moderating role of RPI, expecting that greater RPI would weaken the relationship between perceived and actual peer binge drinking on participant binge drinking. Perceived and actual peer binge drinking were statistically significant predictors of participant binge drinking frequency in the past month, after controlling for covariates. RPI significantly moderated the association between perceptions of peer binge drinking and participant's own binge drinking; this association was weaker among participants with higher RPI compared to those with lower RPI. RPI did not interact with the actual binge drinking behavior of network peers. RPI may function to protect individuals from the effect of their perceptions about the binge drinking of peers, but not from the effect of the actual binge drinking of peers. Copyright © 2017.

Zhang, Niu; Henderson, Charles N.R.

2016-01-01

Objective: The objective of this study was to evaluate the academic impact of cooperative peer instruction during lecture pauses in an immunology/endocrinology course. Methods: Third-quarter students participated across iterations of the course. Each class offered 20 lectures of 50 minutes each. Classes were divided into a peer-instruction group incorporating cooperative peer instruction and a control group receiving traditional lectures. Peer-instruction group lectures were divided into 2–3 short presentations followed by a multiple-choice question (MCQ). Students recorded an initial answer and then had 1 minute to discuss answers with group peers. Following this, students could submit a revised answer. The control group received the same lecture material, but without MCQs or peer discussions. Final-exam scores were compared across study groups. A mixed-design analysis of covariance was used to analyze the data. Results: There was a statistically significant main effect for the peer-instruction activity (F(1, 93) = 6.573, p = .012, r = .257), with recall scores higher for MCQs asked after peer-instruction activities than for those asked before peer instruction. Final-exam scores at the end of term were greater in the peer-instruction group than the control group (F(1, 193) = 9.264, p = .003, r = .214; question type, F(1, 193) = 26.671, p = .000, r = .348). Conclusion: Lectures with peer-instruction pauses increase student recall and comprehension compared with traditional lectures. PMID:26967766

Women who start college in one of the natural or physical sciences leave in greater proportions than their male peers. The reasons for this difference are complex, and one possible contributing factor is the social environment women experience in the classroom. Using social network analysis, we explore how gender influences the confidence that college-level biology students have in each other's mastery of biology. Results reveal that males are more likely than females to be named by peers as being knowledgeable about the course content. This effect increases as the term progresses, and persists even after controlling for class performance and outspokenness. The bias in nominations is specifically due to males over-nominating their male peers relative to their performance. The over-nomination of male peers is commensurate with an overestimation of male grades by 0.57 points on a 4 point grade scale, indicating a strong male bias among males when assessing their classmates. Females, in contrast, nominated equitably based on student performance rather than gender, suggesting they lacked gender biases in filling out these surveys. These trends persist across eleven surveys taken in three different iterations of the same Biology course. In every class, the most renowned students are always male. This favoring of males by peers could influence student self-confidence, and thus persistence in this STEM discipline.

Religious leaders are well respected in most Nigerian communities and are often called in to provide support for terminally-ill patients. Many Nigeria communities still view cancer as a stigmatised disease. This study sought to elicit the perceptions of Christian and Islamic religious leaders and explore problems associated with their involvement in end-of-life care for cancer patients. Participants were recruited among 114 religious leaders. Four focus group discussion sessions were then conducted with open-ended questions on previous involvement in end-of-life care of cancer patients and whether they would like to do more. There were thirty (30) willing participants in all. The discussions were audiotaped, transcribed and coded using the NUDIST software. Ninety of the respondents (62%) would not be involved in end-of-life care. This is because of the fear of peer pressure. The responses could be classified under three major themes were identified: (1) Care supposed to be provided by all religious leaders (2) End-of-Life care in institutions are safer (3) End-of-Life care consumes time. Statements made by respondents include "I will fall out with many if I am found ministering to dying patients". We observe that peer pressure played an important role in the acceptability of end-of-life activities in this group. This could be used in the positive light in designing interventions. © 2015, Published by the BMJ Publishing Group Limited.

Bacon, Cynthia Thornton

The purpose of this study was to describe nurses' needs and how they are being met and not met after caring for surgical patients who died after a failure to rescue (FTR). A qualitative, phenomenologic approach was used for the interview and analysis framework. Methods to ensure rigor and trustworthiness were incorporated into the design. The investigator conducted semistructured 1:1 interviews with 14 nurses. Data were analyzed using Colaizzi's methods. Four themes were identified: (1) coping mechanisms are important; (2) immediate peer and supervisor feedback and support are needed for successful coping; (3) subsequent supervisor support is crucial to moving on; and (4) nurses desire both immediate support and subsequent follow-up from their nurse leaders after every FTR death. Nurses' needs after experiencing an FTR patient death across multiple practice areas and specialties were remarkably similar and clearly identified and articulated. Coping mechanisms vary and are not uniformly effective across different groups. Although most nurses in this study received support from their peers after the FTR event, many nurses did not receive the feedback and support that they needed from their nurse leaders. Immediate nurse leader support and follow-up debriefings should be mandatory after patient FTR deaths. Developing an understanding of nurses' needs after experiencing an FTR event can assist nurse leaders to better support nurses who experience FTR deaths. Insight into the environment surrounding FTR deaths also provides a foundation for future research aimed at improving patient safety and quality through an improved working environment for nurses.

ROAST: Peer Review as a Learning and Assessment Tool in Graduate Education

Science.gov (United States)

Somerville, R. C.

2003-12-01

Constructivist learning theory and inquiry-based educational practice stress the parallels between learning and research. Although peer review has long been a central feature of the working lives of research scientists, it has rarely found its way into the classroom. Motivated by this thought, an imaginary journal, Reviews of Atmospheric Science Topics (ROAST), has been integrated into a graduate-level course in atmospheric thermodynamics. The instructor acts as editor of ROAST. Students in the class are divided into teams and assigned topics on which to write survey papers and give in-class presentations, using the text, the Internet, the library, and other resources. The assigned topics range over the subject matter of the course. The submitted survey papers are sent by the ROAST editor to other members of the class, acting as anonymous reviewers. Just as in the case of real research journals, the editor asks the authors to respond to criticisms of reviewers and then sends the revised papers back to the reviewers. Each student is thus a researcher and co-author of one paper as well as an anonymous reviewer of several others. ROAST has proven to be not only a useful means of fostering learning, but also a natural and effective assessment tool. The peer review mechanism allows the student authors to address the defects in their papers, and hence in their learning, as pointed out not by an authority figure or an examination but by their own peers. As an important side benefit, the students gain experience with the peer review process itself and come to appreciate its strengths and weaknesses in evaluating scientific papers.

Fitting in and feeling good: the relationships among peer alignment, instructor connectedness, and self-efficacy in undergraduate satisfaction with engineering

Science.gov (United States)

Micari, Marina; Pazos, Pilar

2016-07-01

This study examined the relationships among peer alignment (the feeling that one is similar in important ways to one's engineering peers), instructor connectedness (the sense that one knows and looks up to academic staff/faculty members in the department), self-efficacy for engineering class work (confidence in one's ability to successfully complete engineering class work), and engineering students' satisfaction with the major. A total of 135 sophomore (second-year university students) and junior (third-year students) engineering students were surveyed to measure these three variables. A multiple regression analysis showed that self-efficacy, peer alignment, and instructor connectedness predicted student satisfaction with the major, and that self-efficacy acted as a mediator between both peer alignment and instructor connectedness on the one hand, and satisfaction on the other. The authors offer suggestions for practice based on the results.

Origin of Peer Influence in Social Networks

Pinheiro, Flávio L.; Santos, Marta D.; Santos, Francisco C.; Pacheco, Jorge M.

2014-03-01

Social networks pervade our everyday lives: we interact, influence, and are influenced by our friends and acquaintances. With the advent of the World Wide Web, large amounts of data on social networks have become available, allowing the quantitative analysis of the distribution of information on them, including behavioral traits and fads. Recent studies of correlations among members of a social network, who exhibit the same trait, have shown that individuals influence not only their direct contacts but also friends' friends, up to a network distance extending beyond their closest peers. Here, we show how such patterns of correlations between peers emerge in networked populations. We use standard models (yet reflecting intrinsically different mechanisms) of information spreading to argue that empirically observed patterns of correlation among peers emerge naturally from a wide range of dynamics, being essentially independent of the type of information, on how it spreads, and even on the class of underlying network that interconnects individuals. Finally, we show that the sparser and clustered the network, the more far reaching the influence of each individual will be.

Development of Nurse Self-Concept in Nursing Students: The Effects of a Peer-Mentoring Experience.

Science.gov (United States)

Ford, Yvonne

2015-09-01

Positive nurse self-concept has been shown to increase job productivity, retention, and job satisfaction. Student participation in peer-mentoring experiences has been shown to increase self-confidence and understanding of the role of the nurse leader. The Nurse Self-Concept Questionnaire (NSCQ) was used to measure the nurse self-concept of senior baccalaureate nursing students before and after completion of a peer-mentoring experience. Female students scored significantly higher on two subscales of the NSCQ than male students prior to the peer-mentoring experience. This difference was not seen after the experience. Mean changes in scores on all six dimensions of self-concept measured by the NSCQ were significantly higher after the mentoring experience. Further investigation of male students' experiences in clinical settings may be warranted. The experience of mentoring lower-level students offers practice for upper-level nursing students in providing direction, exercising leadership and management skills, and working as a member of the health care team.

Utilisation of a peer assisted learning scheme in an undergraduate diagnostic radiography module

International Nuclear Information System (INIS)

Meertens, R.

2016-01-01

Background: Peer to peer support programmes involve students supporting each other in either an educational, social and/or pastoral way. This is now common place in higher education institutes and has been proven to decrease student attrition and improve grades. Aim: To evaluate a peer assisted learning scheme (PALS) within the University of Exeter undergraduate programme, where final year (stage 3) students held extra-curricular teaching sessions in an on-campus X-ray room throughout the academic term to support a first year (stage 1) module introducing basic projectional radiographic examinations, radiation safety, patient care and radiographic equipment. PALS sessions were unstructured and as such could involve roleplaying radiographic examinations, revisiting lecture material and/or discussing hospital placement or pastoral issues. Methods: Brookfield's four lenses of critical reflection were used. 16 of 63 stage 1 students and 9 of 29 stage 3 students were electronically surveyed upon completion of the PALS sessions. Relevant colleagues and educational specialists were also informally interviewed. These were put in context with autobiographical reflections and the existing literature base on PALS. Results: All agreed that the sessions provided a good environment for stage 1 students to improve their practical skills, revise lecture content, and gain confidence for upcoming clinical placements. Stage 3 students gained experience teaching students, an essential role of a graduate radiographer's job. Improvements around recruiting stage 3 peer leaders, sustainability, timetabling and session structure were explored. Conclusion: The PALS proved to be a successful initiative within the undergraduate programme and will be continued into the future. - Highlights: • Peer Assisted Learning Schemes are an established part of higher education. • Peer Assisted Learning Schemes can reduce student attrition and improve grades. • Peer Assisted Learning

Full Text Available Objective: To evaluate the reliability of a peer evaluation instrument in a longitudinal team-based learning setting. Methods: Student pharmacists were instructed to evaluate the contributions of their peers. Evaluations were analyzed for the variance of the scores by identifying low, medium, and high scores. Agreement between performance ratings within each group of students was assessed via intra-class correlation coefficient (ICC. Results: We found little variation in the standard deviation (SD based on the score means among the high, medium, and low scores within each group. The lack of variation in SD of results between groups suggests that the peer evaluation instrument produces precise results. The ICC showed strong concordance among raters. Conclusions: Findings suggest that our student peer evaluation instrument provides a reliable method for peer assessment in team-based learning settings.

Not even the past: The joint influence of former leader and new leader during leader succession in the midst of organizational change.

Science.gov (United States)

Zhao, Helen H; Seibert, Scott E; Taylor, M Susan; Lee, Cynthia; Lam, Wing

2016-12-01

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

The effect of peer interactions on Newtonian thinking in secondary physics: What are they saying? How does it help?

Science.gov (United States)

Crowe, Jacalyn

Many studies in the field of Physics Education Research (PER) have demonstrated that courses which include a component of interaction among peers achieve significantly higher gains in conceptual understanding. Few of those studies have closely examined the content of those interactions and the role that they play in achieving those gains. This study evaluates the role of peer interaction in children's understanding of Newtonian physics and analyzes the characteristics of peer interaction that are conducive to better learning. The current study took place in a suburban public high school, in a college-preparatory, introductory course in physics. One hundred and seventy eight students were randomly placed in the eight classes participating in the study. Two of the classes were randomly chosen to constitute the treatment group and were taught by the principal investigator. The remaining six classes were taught by five other instructors in the department and served as a control or comparison group. One class session of each instructor was videotaped to assess how class time was typically utilized. In all classes, students used the same textbook, and completed the same problem sets and laboratory investigations. Students in the treatment group participated in peer instruction activities, approximately twice per week, over the course of the semester. Results showed a significant effect of treatment on achievement from pre- to post-test, based on scores on the Force and Motion Conceptual Evaluation (FMCE). Employing peer instruction methods did not require additional instructional time overall. Analysis of classroom videotapes demonstrated that a greater portion of class time is dedicated to active student discussion in classes where peer instruction methods are employed. Conversational data revealed that, in peer discussions, students were routinely involved in conversational mechanisms such as articulating their own thinking, questioning, and explanation. Each of these

Situational moderators of leader reward and punishment behaviors: fact or fiction?

Podsakoff, P M; Todor, W D; Grover, R A; Huber, V L

1984-08-01

One assumption shared by many contemporary models of leadership is that situational variables moderate the relationships between leader behaviors and subordinate responses. Recently, however, R. J. House and J. L. Baetz (1979 in B. Staw & L. Cummings, Eds., Research in Organizational Behavior (Vol. 1), Greenwich, Connecticut, JAI Press) have suggested that the effects of some leader traits and behaviors may be relatively invariant; that is, have the same effects in a variety of situations. One possible class of leader behaviors which may have relatively consistent effects across situations are those known as leader reward and punishment behaviors. The first goal of the research reported here was to increase our understanding of the relationships between leader contingent and noncontingent reward and punishment behaviors and subordinate responses. Contingent reward behavior was found to have the most pronounced relationships with subordinate performance and satisfaction, followed by noncontingent punishment behavior. Neither leader noncontingent reward nor contingent punishment behavior were found to be related to either subordinate performance or satisfaction, with the exception that noncontingent reward behavior was negatively related to subordinates' satisfaction with work. The second goal of the research was to examine the effects of a variety of potential moderators on the relationships between leader reward and punishment behaviors and subordinate responses. The results of this study suggest that the relationships between leader reward and punishment behaviors and subordinates' performance are relatively free of moderating effects.

An increasing number of large-scale applications exploit peer-to-peer network architecture to provide highly scalable and flexible services. Among these applications, data management in peer-to-peer systems is one of the interesting domains. In this paper, we investigate the multidimensional...... skyline computation problem on a structured peer-to-peer network. In order to achieve low communication cost and quick response time, we utilize the iMinMax(\\theta ) method to transform high-dimensional data to one-dimensional value and distribute the data in a structured peer-to-peer network called BATON....... Thereafter, we propose a progressive algorithm with adaptive filter technique for efficient skyline computation in this environment. We further discuss some optimization techniques for the algorithm, and summarize the key principles of our algorithm into a query routing protocol with detailed analysis...

Empowering the people: Development of an HIV peer education model for low literacy rural communities in India

Krupp Karl

2008-04-01

Full Text Available Abstract Background Despite ample evidence that HIV has entered the general population, most HIV awareness programs in India continue to neglect rural areas. Low HIV awareness and high stigma, fueled by low literacy, seasonal migration, gender inequity, spatial dispersion, and cultural taboos pose extra challenges to implement much-needed HIV education programs in rural areas. This paper describes a peer education model developed to educate and empower low-literacy communities in the rural district of Perambalur (Tamil Nadu, India. Methods From January to December 2005, six non-governmental organizations (NGO's with good community rapport collaborated to build and pilot-test an HIV peer education model for rural communities. The program used participatory methods to train 20 NGO field staff (Outreach Workers, 102 women's self-help group (SHG leaders, and 52 barbers to become peer educators. Cartoon-based educational materials were developed for low-literacy populations to convey simple, comprehensive messages on HIV transmission, prevention, support and care. In addition, street theatre cultural programs highlighted issues related to HIV and stigma in the community. Results The program is estimated to have reached over 30 000 villagers in the district through 2051 interactive HIV awareness programs and one-on-one communication. Outreach workers (OWs and peer educators distributed approximately 62 000 educational materials and 69 000 condoms, and also referred approximately 2844 people for services including voluntary counselling and testing (VCT, care and support for HIV, and diagnosis and treatment of sexually-transmitted infections (STI. At least 118 individuals were newly diagnosed as persons living with HIV (PLHIV; 129 PLHIV were referred to the Government Hospital for Thoracic Medicine (in Tambaram for extra medical support. Focus group discussions indicate that the program was well received in the communities, led to improved health

Longest, Beaufort

2017-02-06

Purpose The purpose of this paper is to expand attention to responsible leader behavior in the world's health sectors by explaining how this concept applies to health sectors, considering why health sector leaders should behave responsibly, reviewing how they can do so, and asserting potential impact through an applied example. Design/methodology/approach This paper is a viewpoint, reflecting conceptualizations rooted in leadership literature which are then specifically applied to health sectors. A definition of responsible leader behavior is affirmed and applied specifically in health sectors. Conceptualizations and viewpoints about practice of responsible leader behavior in health sectors and potential consequences are then discussed and asserted. Findings Leadership failures and debacles found in health, but more so in other sectors, have led leadership researchers to offer insights, many of them empirical, into the challenges of leadership especially by more clearly delineating responsible leader behavior. Practical implications Much of what has been learned in the research about responsible leader behavior offers pathways for health sector leaders to more fully practice responsible leadership. Social implications This paper asserts and provides a supporting example that greater levels of responsible leader behavior in health sectors hold potentially important societal benefits. Originality/value This paper is the first to apply emerging conceptualizations and early empirical findings about responsible leader behavior specifically to leaders in health sectors.

Medical leadership is increasingly considered as crucial for improving the quality of care and the sustainability of healthcare. However, conceptual clarity is lacking in the literature and in practice. Therefore, a systematic review of the scientific literature was conducted to reveal the different conceptualizations of medical leadership in terms of definitions, roles and activities, and personal-and context-specific features. Eight databases were systematically searched for eligible studies, including empirical studies published in peer-reviewed journals that included physicians carrying out a manager or leadership role in a hospital setting. Finally, 34 articles were included and their findings were synthesized and analyzed narratively. Medical leadership is conceptualized in literature either as physicians with formal managerial roles or physicians who act as informal 'leaders' in daily practices. In both forms, medical leaders must carry out general management and leadership activities and acts to balance between management and medicine, because these physicians must accomplish both organizational and medical staff objectives. To perform effectively, credibility among medical peers appeared to be the most important factor, followed by a scattered list of fields of knowledge, skills and attitudes. Competing logics, role ambiguity and a lack of time and support were perceived as barriers. However, the extent to which physicians must master all elicited features, remains ambiguous. Furthermore, the extent to which medical leadership entails a shift or a reallocation of tasks that are at the core of medical professional work remains unclear. Future studies should implement stronger research designs in which more theory is used to study the effect of medical leadership on professional work, medical staff governance, and subsequently, the quality and efficiency of care.

The Self, the Peer and the Teacher in the EFL Pronunciation Class: A Comparative Study on Assessment, Perceptions and Systematicity

Full Text Available This pilot study is aimed at describing, analysing and comparing self, peer and teacher quantitative and qualitative assessment (and consequently also perceptions and degree of systematicity when assessing in the English as a Foreign Language (EFL pronunciation class in tertiary education. Accordingly, the main objectives of this study have been to measure, rank and compare the harshness or leniency of the three different types of raters involved and their consistency/systematicity when in this role, as well as to measure the levels of coincidence and/or discrepancy when evaluating from different roles and depending on quantitative or qualitative considerations. The method used for the analysis involves the quantitative and qualitative analyses of the scores obtained in a triple-role assessment task carried out by 16 students and a teacher. The calculation of various statistical measures, the triangulation of the data obtained and the Many-Facet Rasch Measurement analysis of the results have completed the study and constitute the departure point for further larger studies. From the results obtained, it can be highlighted that quantitatively, the self and the teacher’s perceptions seem to be the ones that are more distant or different, whereas the self and the peer's tend to be the most similar. In the same way, qualitative assessments seem to be more lenient, that is to say, slightly higher in mean score and have a lower coefficient of variation than quantitative ones in the three groups analysed. Consistency/systematicity is relatively high but it is still an aspect to be improved on the part of most raters.

Patterns of adjustment for youth victimized by peers vary depending on whether youth are identified as victims through self-reports, peer-reports, or both. In order to provide more targeted strategies that may help mitigate negative consequences associated with specific victimization groups, more information is needed about how these youth perceive their school ecology (bullying and academic ecology), their feelings of school belonging, and their valuing of school. Based on the convergence of self- and peer-reports of victimization, we identified four victim groups from a sample of students in 5th grade classrooms (N = 1360; 52.8% girls, 53.1% White, 34.6% Black or Hispanic, 12.2% Native American, Asian, or other) using Latent Profile Analysis (LPA): convergent victims (high self- and peer-reports), self-identified victims (high self-, low peer-reports), peer-identified victims (low self-, high peer-reports), and nonvictims (low self- and peer-reports). Convergent victims' perceptions were similar to nonvictims with key differences being convergent victims' greater willingness to protect peers being bullied but lower feelings of school belonging compared to nonvictims. Peer-identified and self-identified victims perceived differences in the bullying and academic ecology including peer-identified victims' greater willingness to protect peers and expectations for more peers to encourage bulling against them compared to self-identified victims. However, both peer- and self-identified victims perceived greater emotional risk of participating in class and had lower feelings of school belonging compared to nonvictims. Implications for supporting youth with divergent self- and peer-reported victimization status as they transition to middle school are discussed.

Preventing DoS attacks in peer-to-peer media streaming systems

Conner, William; Nahrstedt, Klara; Gupta, Indranil

2006-01-01

This paper presents a framework for preventing both selfishness and denial-of-service attacks in peer-to-peer media streaming systems. Our framework, called Oversight, achieves prevention of these undesirable activities by running a separate peer-to-peer download rate enforcement protocol along with the underlying peer-to-peer media streaming protocol. This separate Oversight protocol enforces download rate limitations on each participating peer. These limitations prevent selfish or malicious nodes from downloading an overwhelming amount of media stream data that could potentially exhaust the entire system. Since Oversight is based on a peer-to-peer architecture, it can accomplish this enforcement functionality in a scalable, efficient, and decentralized way that fits better with peer-to-peer media streaming systems compared to other solutions based on central server architectures. As peer-to-peer media streaming systems continue to grow in popularity, the threat of selfish and malicious peers participating in such large peer-to-peer networks will continue to grow as well. For example, since peer-to-peer media streaming systems allow users to send small request messages that result in the streaming of large media objects, these systems provide an opportunity for malicious users to exhaust resources in the system with little effort expended on their part. However, Oversight addresses these threats associated with selfish or malicious peers who cause such disruptions with excessive download requests. We evaluated our Oversight solution through simulations and our results show that applying Oversight to peer-to-peer media streaming systems can prevent both selfishness and denial-of-service attacks by effectively limiting the download rates of all nodes in the system.

The Hartford Gerontological Nursing Leaders (HGNL) formerly known as the Building Academic Geriatric Nursing Capacity Initiative (BAGNC), in conjunction with the National Hartford Centers of Gerontological Nursing Excellence (NHCGNE), developed and executed a peer mentoring program beginning in 2011 to enhance both (a) the experience of newly selected scholars and fellows to the NHCGNE and (b) the ongoing professional development of HGNL members. The purpose of this article is to describe key strategies used to develop and execute the peer mentoring program and to present formative program evaluation. The program was launched in January 2011 with seven peer mentor and mentee matches. In June 2012, the peer mentoring committee solicited feedback on the development of the peer mentoring program and changes were made for the subsequent cohorts. An additional 12 matches were made in the following 2 years (2012 and 2013), for a total of 31 matches to date. We have learned several key lessons from our three cohorts regarding how to structure, implement, and carefully evaluate a peer mentoring program. Informal evaluation of our peer mentoring program noted several challenges for both peer mentors and mentees. Having knowledge of and addressing those challenges may increase the overall quality and effectiveness of peer mentoring programs and, in turn, benefit academic nursing by strengthening the faculty workforce. Findings from development and implementation of a peer mentoring program for gerontological faculty could lead to new and adaptable programs in a variety of clinical and education settings. © 2015 Sigma Theta Tau International.

Delay-sensitive content distribution with peer-to-peer (P2P) cooperation in public safety vehicular networks is investigated. Two cooperative schemes are presented and analyzed. The first scheme is based on unicasting from the base station, whereas the second is based on threshold based multicasting. Long Term Evolution (LTE) is used for long range (LR) communications with the base station (BS) and IEEE 802.11p is considered for inter-vehicle collaboration on the short range (SR). The first scheme is shown to outperform non-cooperative unicasting and multicasting, while the second scheme outperforms non-cooperative unicasting beyond a specific number of cooperating vehicles, when the appropriate 802.11p power class is used. The first scheme achieves the best performance among the compared methods, and a practical approximation of that scheme is shown to be close to optimal performance. © 2014 Elsevier B.V.

On the Transition from Initial Leader to Stepped Leader in Negative Cloud-to-ground Lightning

Stolzenburg, M.; Marshall, T. C.; Karunarathne, S.; Orville, R. E.

2017-12-01

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

The outcome of children with an out-of-hospital cardiac arrest is still poor, but bystander cardiopulmonary resuscitation can increase survival and minimise severe neurological sequelae. While teaching basic life support is standardised in emergency medicine classes, paediatric basic life support (PBLS) in neonates and toddlers is under-represented in paediatric curricula during university education. The appropriate mixture of E-learning and peer teaching lessons remains controversial in teaching paediatric basic skills. However, an increasing number of medical schools and paediatric classes switch their curricula to much cheaper and less tutor-dependent E-learning modules. We hypothesise that a peer teaching lesson is superior to a PBLS video demonstration with co-extensive contents and improves knowledge, skills and adherence to resuscitation guidelines. Eighty-eight medical students were randomly assigned to a video PBLS lesson (n = 44) or a peer teaching group (n = 44). An objective structured clinical examination was performed immediately after the class and at the end of the semester. Students taught by a peer teacher performed significantly better immediately after the initial course and at the end of the semester when compared to the video-trained group (P = 0.008 and P = 0.003, respectively). In addition, a borderline regression analysis also revealed a better resuscitation performance of students instructed in the peer teaching group. In our setting, peer teaching is superior and more sustainable than a co-extensive video demonstration alone when teaching PBLS to medical students. However, additional studies with combinations of different teaching methods are necessary to evaluate long-term outcomes. © 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

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

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

To evaluate an interprofessional peer-teaching activity during which physical therapy students instructed undergraduate pharmacy students on 3 ambulatory devices (canes, crutches, walkers). The pre/post evaluation of 2 pharmacy undergraduate classes included 220 students, 110 per year. After pharmacy students completed a 10-point, knowledge-based pretest, they participated in a hands-on activity with physical therapy students teaching them about sizing, use, and safety of canes, crutches, and walkers. A 10-point posttest was completed immediately afterward. The mean difference of pre/post scores was 3.5 (SD 1.9) for the peer-led teaching, and 3.8 (SD 2.2) for the peer learning group. Students had positive responses regarding the learning exercise and recommended further peer teaching. The peer-learning activity involving physical therapy students teaching pharmacy students was an effective method of improving knowledge and skills regarding basic ambulatory devices.

Quality assurance in radiology: peer review and peer feedback

International Nuclear Information System (INIS)

Strickland, N.H.

2015-01-01

Peer review in radiology means an assessment of the accuracy of a report issued by another radiologist. Inevitably, this involves a judgement opinion from the reviewing radiologist. Peer feedback is the means by which any form of peer review is communicated back to the original author of the report. This article defines terms, discusses the current status, identifies problems, and provides some recommendations as to the way forward, concentrating upon the software requirements for efficient peer review and peer feedback of reported imaging studies. Radiologists undertake routine peer review in their everyday clinical practice, particularly when reporting and preparing for multidisciplinary team meetings. More formal peer review of reported imaging studies has been advocated as a quality assurance measure to promote good clinical practice. It is also a way of assessing the competency of reporting radiologists referred for investigation to bodies such as the General Medical Council (GMC). The literature shows, firstly, that there is a very wide reported range of discrepancy rates in many studies, which have used a variety of non-comparable methodologies; and secondly, that applying scoring systems in formal peer review is often meaningless, unhelpful, and can even be detrimental. There is currently a lack of electronic peer feedback system software on the market to inform radiologists of any review of their work that has occurred or to provide them with clinical outcome information on cases they have previously reported. Learning opportunities are therefore missed. Radiologists should actively engage with the medical informatics industry to design optimal peer review and feedback software with features to meet their needs. Such a system should be easy to use, be fully integrated with the radiological information and picture archiving systems used clinically, and contain a free-text comment box, without a numerical scoring system. It should form a temporary record

Optimization of routing strategies for data transfer in peer-to-peer networks

Morioka, Atsushi; Igarashi, Akito

2014-01-01

Since peer-to-peer file-sharing systems have become familiar recently, the information traffic in the networks is increasing. Therefore it causes various traffic problems in peer-to-peer networks. In this paper, we model some features of the peer-to-peer networks, and investigate the traffic problems. Peer-to-peer networks have two notable characters. One is that each peer frequently searches for a file and download it from a peer who has the requested file. To decide whether a peer has the requested file or not in modelling of the search and download process, we introduce file-parameter P j , which expresses the amount of files stored in peer j. It is assumed that if P j is large, peer j has many files and can meet other peers' requests with high probability. The other character is that peers leave and join into the network repeatedly. Many researchers address traffic problems of data transfer in computer communication networks. To our knowledge, however, no reports focus on those in peer-to-peer networks whose topology changes with time. For routing paths of data transfer, generally, the shortest paths are used in usual computer networks. In this paper, we introduce a new optimal routing strategy which uses weights of peers to avoid traffic congestion. We find that the new routing strategy is superior to the shortest path strategy in terms of congestion frequency in data transfer

Argumentation Skills: A Peer Assessment Approach to Discussions in the EFL Classroom

2016-07-01

Full Text Available This paper presents an exploratory action research study carried out by two English as a foreign language teachers in a private, non-profit institution in Bogota, Colombia, with a group of 12 learners in a B1 English course. These students faced difficulties elaborating on their ideas when discussing issues in class. The study placed emphasis on the use of argumentation outlines and peer assessment to boost learners’ argumentative abilities. Audio-taped conversations and open-ended interviews were used to understand the impact on the pedagogical intervention. Findings revealed that argumentation outlines and peer assessment can promote learners’ awareness and ability to engage in argumentation processes. Moreover, peer assessment appears to be an essential tool for enhancing personal and collaborative learning, as well as for promoting learner reflection and agency.

EFL LEARNERS REPAIR SEQUENCE TYPES ANALYSIS AS PEER- ASSESSMENT IN ORAL PERFORMANCE

Full Text Available There are certain concerns that EFL teacher needs to observe in assessing students oral performance, such as the amount of words which the learners utter, the grammatical errors that they make, the hesitation and certain expression that they produce. This paper attempts to give overview of research results using qualitative method which show the impacts of repair sequence types analysis on those elements needed to be observed as students peer and self-assessment to enhance their speaking ability. The subject was tertiary level learners of English Department, State University of Semarang, Indonesia in 2012. Concerning the repair types, there are four repair sequences as reviewed by Buckwalter (2001, they are Self-Initiated Self Repair (SISR, Self-Initiated Other Repair (SIOR, Other-Initiated Self Repair (OISR, and Other-Initiated Other Repair (OIOR. Having the repair sequences types anaysis, the students investigated the repair sequence of their peers while they performed in class conversation. The modified peer- assessment guideline as proposed by Brown (2004 was used in identifying, categorizing and classifying the types of repair sequences in their peers oral performance. While, the peer-assessment can be a valuable additional means to improve students speaking since it is one of the motives that drive peer- evaluation, along with peer- verification, also peer and self- enhancement. The analysis results were then interpreted to see whether there was significant finding related to the students’ oral performance enhancement.

Athletic trainers are in positions of leadership. To determine self-reported leadership practices of head athletic trainers (HATCs) and program directors (PDs). Cross-sectional study. Respondents' academic institutions. A total of 238 athletic training leaders completed the Leadership Practices Inventory. Of these, 50.4% (n = 120) were HATCs and 49.6% (n = 118) were PDs; 69.3% (n = 165) were men and 30.7% (n = 73) were women; almost all respondents (97.1%, n = 231) were white. Respondents typically reported having 11 to 15 years of experience as an athletic trainer (n = 57, 23.9%) and being between the ages of 30 and 39 years (n = 109, 45.8%). Categories of leadership behaviors (ie, Model, Inspire, Challenge, Encourage, and Enable) were scored from 1 (almost never) to 10 (almost always). Item scores were summed to compute mean category scores. We analyzed demographic information; used t ratios to compare the data from athletic training leaders (PDs and HATCs) with normative data; compared sex, age, position, ethnicity, and years of experience with leadership practices; and computed mean scores. Athletic training leaders reported using leadership behaviors similar to those of other leaders. The PDs reported using inspiring, challenging, enabling, and encouraging leadership behaviors more often than did the HATCs. No differences were found by ethnicity, age, years of experience, or leadership practices. Athletic training leaders are transformational leaders. Athletic training education program accreditation requirements likely account for the difference in leadership practices between PDs and HATCs.

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

In accordance with the purpose and objectives of the study, we used a set of socio-psychological methods and techniques: sociometry, referentometry, a method of defining informal intragroup power structure in a contact community, S. Bem questionnaire (traditional and modified versions. The study involved 138 adolescents, studying at VI-VIII grades of Moscow secondary schools, aged 12 to 14 years. It is shown that the teenagers’ ideas about the leader contain pronounced masculine features. It is proved that gender-typed behavior is more typical of low-status students.

Quality assurance in radiology: peer review and peer feedback.

Science.gov (United States)

Strickland, N H

2015-11-01

Peer review in radiology means an assessment of the accuracy of a report issued by another radiologist. Inevitably, this involves a judgement opinion from the reviewing radiologist. Peer feedback is the means by which any form of peer review is communicated back to the original author of the report. This article defines terms, discusses the current status, identifies problems, and provides some recommendations as to the way forward, concentrating upon the software requirements for efficient peer review and peer feedback of reported imaging studies. Radiologists undertake routine peer review in their everyday clinical practice, particularly when reporting and preparing for multidisciplinary team meetings. More formal peer review of reported imaging studies has been advocated as a quality assurance measure to promote good clinical practice. It is also a way of assessing the competency of reporting radiologists referred for investigation to bodies such as the General Medical Council (GMC). The literature shows, firstly, that there is a very wide reported range of discrepancy rates in many studies, which have used a variety of non-comparable methodologies; and secondly, that applying scoring systems in formal peer review is often meaningless, unhelpful, and can even be detrimental. There is currently a lack of electronic peer feedback system software on the market to inform radiologists of any review of their work that has occurred or to provide them with clinical outcome information on cases they have previously reported. Learning opportunities are therefore missed. Radiologists should actively engage with the medical informatics industry to design optimal peer review and feedback software with features to meet their needs. Such a system should be easy to use, be fully integrated with the radiological information and picture archiving systems used clinically, and contain a free-text comment box, without a numerical scoring system. It should form a temporary record

Arthurs, Leilani A.; Kreager, Bailey Zo

2017-10-01

Engaging students in active learning is linked to positive learning outcomes. This study aims to synthesise the peer-reviewed literature about 'active learning' in college science classroom settings. Using the methodology of an integrative literature review, 337 articles archived in the Educational Resources Information Center (ERIC) are examined. Four categories of in-class activities emerge: (i) individual non-polling activities, (ii) in-class polling activities, (iii) whole-class discussion or activities, and (iv) in-class group activities. Examining the collection of identified in-class activities through the lens of a theoretical framework informed by constructivism and social interdependence theory, we synthesise the reviewed literature to propose the active learning strategies (ALSs) model and the instructional decisions to enable active learning (IDEAL) theory. The ALS model characterises in-class activities in terms of the degrees to which they are designed to promote (i) peer interaction and (ii) social interdependence. The IDEAL theory includes the ALS model and provides a framework for conceptualising different levels of the general concept 'active learning' and how these levels connect to instructional decision-making about using in-class activities. The proposed ALS model and IDEAL theory can be utilised to inform instructional decision-making and future research about active learning in college science courses.

Case study of physician leaders in quality and patient safety, and the development of a physician leadership network.

Hayes, Chris; Yousefi, Vandad; Wallington, Tamara; Ginzburg, Amir

2010-01-01

There is increasing recognition of the need for physician leadership in quality and patient safety, and emerging evidence that physician leadership contributes to improved care. Hospitals are beginning to establish physician leader positions; however, there is little guidance on how to define these roles and the strategies physician leaders can use toward improving care. This case study examines the roles of four physician leaders, describes their contribution to the design and implementation of hospital quality and patient safety agendas and discusses the creation of a physician network to support these activities. The positions were established between July 2006 and April 2009. All are corporate roles with varying reporting and accountability structures. The physician leads are involved in strategic planning, identifying and leading quality and safety initiatives, physician engagement and culture change. All have significantly contributed to the implementation of hospital improvement activities and are seen as influential among their peers as resources and mentors for local project success. Despite their accomplishments, these physician leads have been challenged by ambiguous role descriptions and difficulty identifying effective improvement strategies. As such, an expanding physician network was created with the goal of sharing approaches and tools and creating new strategies. Physician leaders are an important factor in the improvement of safety and quality within hospitals. This case study provides a template for the creation of such positions and highlights the importance of networking as an effective strategy for improving local care and advancing professional development of physician leaders in quality and patient safety.

Full Text Available An investigation of whether and to what extent a peer-led model is able to counteract mechanisms underlying bullying in peer groups, seeking clarification of divergence in reported results on the efficacy of peer-led models. Two studies were carried out in Italy within a project tackling bullying and cyberbullying in secondary schools. In the first study (n= 386, concerning the first phase of the project, a significant decrease was found only for cyberbullying, most of all for male peer educators. For the second study (n= 375 the model was improved and significant effects were found for several participating groups (peer educators and the experimental classes, who exhibited a decrease in bullying, victimization, and cybervictimization. Results suggest that peer educators can act as agents of change in the broader context.

Narcissistic leaders: An asset or a liability? Leader visibility, follower responses, and group-level absenteeism.

Nevicka, Barbara; Van Vianen, Annelies E M; De Hoogh, Annebel H B; Voorn, Bart C M

2018-03-19

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

A CASE STUDY OF COMBINED PEER-TEACHER FEEDBACK ON PARAGRAPH WRITING AT A UNIVERSITY IN THAILAND

Directory of Open Access Journals (Sweden)

Nguyen Thi Thuy Loan

2017-09-01

Full Text Available Writing in English is challenging for ESL writers, so feedback is crucial in assisting them. Although several studies have been conducted on the effectiveness of peer and teacher-feedback in ESL writing, studies on the combined peer-teacher feedback model tend to be scarce. This study thus reported on the combined feedback model in two paragraph-writing classes of sixty students at a university in Thailand where English is taught as a foreign language, students are reported to be passive in class activities and most writing programs are still taught using the traditional method. Students’ peer comments (both valid and invalid ones, their revisions based on both their peers’ and teacher’s feedback (correct and incorrect revisions and their grades on each paragraph were recorded, and a five-point Likert scale survey and a focus group interview were conducted. The findings indicated its success in terms of students’ positive attitudes towards this feedback model, the usefulness of peer comments, high percentages of feedback incorporations and the high overall writing scores. This paper is thus expected to shed some light on how Thai university students with their passive style of learning English positively react to this interactive activity and partly reflect how in-service teachers adjust feedback strategies in their actual teaching situations.

Aarons, Gregory A; Ehrhart, Mark G; Torres, Elisa M; Finn, Natalie K; Beidas, Rinad S

2017-02-01

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

Less than half of all U.S. adults meet the 2008 Physical Activity Guidelines. Leader behaviors and group cohesion have been associated with increased participation or adherence in sports team and exercise class settings. Physical activity interventions in community settings that encompass these factors may enhance intervention adherence. The purpose of this study is to examine the impact of Community Health Promoter leader behaviors and group cohesion on participation in a walking group intervention among racially/ethnically diverse adults in low to moderate-income communities in Detroit, Michigan. Data for the current study were drawn from the Walk Your Heart to Health (WYHH) data set. WYHH was a multisite cluster RCT with a lagged intervention and outcome measurements at baseline and 4, 8, and 32 weeks. Pooled survey data from both intervention arms were used for the current study. Data were analyzed between August 2013 and October 2014. A total of 603 non-Hispanic black, non-Hispanic white, and Hispanic adults across five cohorts that began the 32-week WYHH intervention between March 2009 and October 2011. The intervention was a 32-week walking group program hosted by community- and faith-based organizations and facilitated by Community Health Promoters. Walking groups met three times per week for 90 minutes per session. To promote participation in or adherence to WYHH, Community Health Promoters used evidence-based strategies to facilitate group cohesion. Group members assumed increasing leadership responsibility for facilitating sessions over time. Participation in WYHH as measured by consistency of attendance. Community Health Promoter leader behaviors were positively associated with participation in WYHH. Social but not task cohesion was significantly associated with consistent participation. Social cohesion may mediate the relationship between leader behaviors and walking group participation. Providing leaders with training to build socially cohesive groups

Development of physician leadership competencies: perceptions of physician leaders, physician educators and medical students.

McKenna, Mindi K; Gartland, Myles P; Pugno, Perry A

2004-01-01

Research regarding the development of healthcare leadership competencies is widely available. However, minimal research has been published regarding the development of physician leadership competencies, despite growing recognition in recent years of the important need for effective physician leadership. Usingdata from an electronically distributed, self-administered survey, the authors examined the perceptions held by 110 physician leaders, physician educators, and medical students regarding the extent to which nine competencies are important for effective physician leadership, ten activities are indicative of physician leadership, and seven methods are effective for the development of physician leadership competencies. Results indicated that "interpersonal and communication skills" and "professional ethics and social responsibility" are perceived as the most important competencies for effective physician leadership. Furthermore, respondents believe "influencing peers to adopt new approaches in medicine" and "administrative responsibility in a healthcare organization" are the activities most indicative of effective physician leadership. Finally, respondents perceive"coaching or mentoring from an experienced leader" and "on-job experience (e.g., a management position)" as the most effective methods for developing physician leadership competencies. The implications of these findings for the education and development of physician leaders are discussed.

Problem-based writing with peer review improves academic performance in physiology.

Pelaez, Nancy J

2002-12-01

The aim of this study was to determine whether problem-based writing with peer review (PW-PR) improves undergraduate student performance on physiology exams. Didactic lectures were replaced with assignments to give students practice explaining their reasoning while solving qualitative problems, thus transferring the responsibility for abstraction and generalization to the students. Performance on exam items about concepts taught using PW-PR was compared with performance on concepts taught using didactic lectures followed by group work. Calibrated Peer Review, a Web-delivered program, was used to collect student essays and to manage anonymous peer review after students "passed" three calibration peer reviews. Results show that the students had difficulty relating concepts. Relationship errors were categorized as (1) problems recognizing levels of organization, (2) problems with cause/effect, and (3) overgeneralizations. For example, some described cells as molecules; others thought that vesicles transport materials through the extracellular fluid. With PW-PR, class discussion was used to confront and resolve such difficulties. Both multiple-choice and essay exam results were better with PW-PR instead of lecture.

Distinctive role of opinion leaders in the social networks of school adolescents: an investigation of e-cigarette use.

Gentina, E; Kilic, D; Dancoine, P-F

2017-03-01

This study examines a diverse set of social motives (e.g. peer support, peer pressure, social loneliness) for e-cigarette use, through the mediating effects of opinion leadership, among both male and female adolescents. Prospective cohort study. The data were obtained from a survey conducted among 666 adolescents across 14 school classes, namely, students at three urban schools, public and private, in Lille, France. The proposed integrative model includes social motives, opinion leadership and e-cigarette use in a trilateral relationship; gender is proposed and tested as a potential moderator in a structural equation model. More positive peer support is negatively associated with opinion leadership and e-cigarette use. Both loneliness and susceptibility to peer influence are positively related to opinion leadership and e-cigarette use. Moreover, social support from peers and opinion leadership shape e-cigarette use differently across genders. Policy makers should account for the various (positive and negative) roles of peers and consider the gender of their audience when designing anti-e-cigarette policies.

The impact of previous leaders on the evaluation of new leaders: an alternative to prototype matching.

Science.gov (United States)

Ritter, Barbara A; Lord, Robert G

2007-11-01

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

2005-01-01

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

Class-first analysis in a continuum: an approach to the complexities of schools, society, and insurgent science

Valdiviezo, Laura Alicia

2010-06-01

This essay addresses Katherine Richardson Bruna's paper: Mexican Immigrant Transnational Social Capital and Class Transformation: Examining the Role of Peer Mediation in Insurgent Science, through five main points . First, I offer a comparison between the traditional analysis of classism in Latin America and Richardson Bruna's call for a class-first analysis in the North American social sciences where there has been a tendency to obviate the specific examination of class relations and class issues. Secondly, I discuss that a class-first analysis solely cannot suffice to depict the complex dimensions in the relations of schools and society. Thus, I suggest a continuum in the class-first analysis. Third, I argue that social constructions surrounding issues of language, ethnicity, and gender necessarily intersect with issues of class and that, in fact, those other constructions offer compatible epistemologies that aid in representing the complexity of social and institutional practices in the capitalist society. Richardson Bruna's analysis of Augusto's interactions with his teacher and peers in the science class provides a fourth point of discussion in this essay. As a final point in my response I discuss Richardson Bruna's idea of making accessible class-first analysis knowledge to educators and especially to science teachers.

Analysis of Student Performance in Peer Led Undergraduate Supplements

Science.gov (United States)

Gardner, Linda M.

Foundations of Chemistry courses at the University of Kansas have traditionally accommodated nearly 1,000 individual students every year with a single course in a large lecture hall. To develop a more student-centered learning atmosphere, Peer Led Undergraduate Supplements (PLUS) were introduced to assist students, starting in the spring of 2010. PLUS was derived from the more well-known Peer-Led Team Learning with modifications to meet the specific needs of the university and the students. The yearlong investigation of PLUS Chemistry began in the fall of 2012 to allow for adequate development of materials and training of peer leaders. We examined the impact of academic achievement for students who attended PLUS sessions while controlling for high school GPA, math ACT scores, credit hours earned in high school, completion of calculus, gender, and those aspiring to be pharmacists (i.e., pre-pharmacy students). In a least linear squares multiple regression, PLUS participants performed on average one percent higher on exam scores for Chemistry 184 and four tenths of a percent on Chemistry 188 for each PLUS session attended. Pre-pharmacy students moderated the effect of PLUS attendance on chemistry achievement, ultimately negating any relative gain associated by attending PLUS sessions. Evidence of gender difference was demonstrated in the Chemistry 188 model, indicating females experience a greater benefit from PLUS sessions. Additionally, an item analysis studied the relationship between PLUS material to individual items on exams. The research discovered that students who attended PLUS session, answered the items correctly 10 to 20 percent more than their comparison group for PLUS interrelated items and no difference to 10 percent for non-PLUS related items. In summary, PLUS has a positive effect on exam performance in introductory chemistry courses at the University of Kansas.

Prothero, W. A.

Scientists must have in-depth background knowledge of their subject area and know where current knowledge can be advanced. They perform experiments that gather data to test new or existing theories, present their findings at meetings, publish their results, critically review the results of others, and respond to the reviews of their own work. In the context of a course, these activities correspond to learning the background material by listening to lectures or reading a text, formulating a problem, exploring data using student friendly data access and plotting software, giving brief talks to classmates in a small class or lab setting, writing a science paper or lab report, reviewing the writing of their peers, and receiving feedback (and grades) from their instructors and/or peers. These activities can be supported using course management software and online resources. The "LearningWithData" software system allows solid Earth (focused on plate tectonics) data exploration and plotting. Ocean data access, display, and plotting are also supported. Background material is delivered using animations and slide show type displays. Students are accountable for their learning through included homework assignments. Lab and small group activities provide support for data exploration and interpretation. Writing is most efficiently implemented using the "Calibrated Peer Review" method. This methodology is available at http://cpr.molsci.ucla.edu/. These methods have been successfully implemented in a large oceanography class at UCSB.

Adolescence is a key period of social development at the end of which individuals are expected to take on adult social roles. The school class, as the most salient peer group, becomes the prime environment that impacts social development during adolescence. Using social network analyses, we investigated how individual and group level features are related to prosocial behavior and social capital (generalized trust). We mapped the social networks within 22 classrooms of adolescents aged between 12 and 18 years (N = 611), and collected data on social behaviors towards peers. Our results indicate that individuals with high centrality show both higher levels of prosocial behavior and relational aggression. Importantly, greater social cohesion in the classroom was associated with (1) reduced levels of antisocial behavior towards peers and (2) increased generalized trust. These results provide novel insights in the relationship between social structure and social behavior, and stress the importance of the school environment in the development of not only intellectual but also social capital.

Full Text Available Peer teaching is recognized as a powerful instructional method; however, there is a paucity of studies that have evaluated the outcomes experienced by peer-teachers and their student recipients in the context of trained, non-reciprocal, high school physical education. Accordingly, the effectiveness of a formalized and trained non-reciprocal peer teaching (T-PT program upon psychosocial, behavioral, pedagogical and student learning outcomes within high school physical education classes was investigated. Students from eight intact classes (106 males, 94 females, Mage = 12.46, SD = 0.59 were randomly assigned to either a T-PT intervention group (taught by a volunteer peer-teacher who was trained in line with a tactical games approach or untrained group (U-PT; where volunteer peer-teachers received no formal training, but did receive guidance on the game concepts to teach. Data were collected over 10 lessons in a 5-week soccer unit. Mixed-model ANOVAs/MANOVAs revealed that, in comparison to U-PT, the T-PT program significantly enhanced in-game performance actions and academic learning time among student recipients. Those in the T-PT also provided greater levels of feedback and structured learning time, as well as reporting more positive feelings about peer teaching and fewer perceived barriers to accessing learning outcomes. These findings show that non-reciprocal peer-teachers who receive formalized support through training and tactical games approach-based teaching resources can enhance behavioral, pedagogical, and motor performance outcomes in physical education.

Seeger, M; Niemeyer, L; Bujotzek, M

2009-01-01

The breakdown mechanism of compressed SF 6 in gas insulation is known to be controlled by stepped leader propagation. This process is still not well understood in uniform and weakly non-uniform background fields with small electrode protrusions, such as particles or surface roughness. In a previous publication an investigation of partial discharges and breakdown in uniform background fields that focused on streamer and leader inception mechanisms was presented (Seeger et al 2008 J. Phys. D: Appl. Phys. 41 185204). In this paper we present for the first time a physical leader propagation model that consistently describes the observed phenomena in uniform background fields in SF 6 . The model explains two different types of leader breakdown; these can be associated with the precursor and the stem mechanisms. It also yields the parameters of stepped leader propagation, which include step lengths, associated step charges, step times and fields and temperatures in the leader channel. Further, it explains the features of arrested leaders in uniform background fields. The model predicts the range of parameters under which arrested and breakdown leaders occur in good agreement with the experimental data.

Conceptual question response times in Peer Instruction classrooms

Directory of Open Access Journals (Sweden)

Kelly Miller

2014-08-01

Full Text Available Classroom response systems are widely used in interactive teaching environments as a way to engage students by asking them questions. Previous research on the time taken by students to respond to conceptual questions has yielded insights on how students think and change conceptions. We measure the amount of time students take to respond to in-class, conceptual questions [ConcepTests (CTs] in two introductory physics courses taught using Peer Instruction and use item response theory to determine the difficulty of the CTs. We examine response time differences between correct and incorrect answers both before and after the peer discussion for CTs of varying difficulty. We also determine the relationship between response time and student performance on a standardized test of incoming physics knowledge, precourse self-efficacy, and gender. Our data reveal three results of interest. First, response time for correct answers is significantly faster than for incorrect answers, both before and after peer discussion, especially for easy CTs. Second, students with greater incoming physics knowledge and higher self-efficacy respond faster in both rounds. Third, there is no gender difference in response rate after controlling for incoming physics knowledge scores, although males register significantly more attempts before committing to a final answer than do female students. These results provide insight into effective CT pacing during Peer Instruction. In particular, in order to maintain a pace that keeps everyone engaged, students should not be given too much time to respond. When around 80% of the answers are in, the ratio of correct to incorrect responses rapidly approaches levels indicating random guessing and instructors should close the poll.

Whereas early peer-to-peer platforms were designed to enable file sharing and goods trading, we recently witness the emergence of a new breed of peer-to-peer platforms that are designed for ordinary service sharing. Ordinary services entail intangible provisions and are defined as an economic...... activity that generates immaterial benefits and does not result in ownership of material goods. Based on a structured analysis of 41 internet-based rideshare platforms, we explore and layout the unique characteristics of peer-to-peer service sharing platforms based on three distinct temporal patterns...

Stepped-to-dart Leaders in Cloud-to-ground Lightning

Stolzenburg, M.; Marshall, T. C.; Karunarathne, S.; Karunarathna, N.; Warner, T.; Orville, R. E.

2013-12-01

Using time-correlated high-speed video (50,000 frames per second) and fast electric field change (5 MegaSamples per second) data for lightning flashes in East-central Florida, we describe an apparently rare type of subsequent leader: a stepped leader that finds and follows a previously used channel. The observed 'stepped-to-dart leaders' occur in three natural negative ground flashes. Stepped-to-dart leader connection altitudes are 3.3, 1.6 and 0.7 km above ground in the three cases. Prior to the stepped-to-dart connection, the advancing leaders have properties typical of stepped leaders. After the connection, the behavior changes almost immediately (within 40-60 us) to dart or dart-stepped leader, with larger amplitude E-change pulses and faster average propagation speeds. In this presentation, we will also describe the upward luminosity after the connection in the prior return stroke channel and in the stepped leader path, along with properties of the return strokes and other leaders in the three flashes.

Full Text Available Besides leading theories of people in one way or another from different angles reveal the types of leaders who can meet in business management literature contains classifications of management styles, which take into account different criteria or viewpoints. The word “leadership‟ has been used in various aspects of human endeavor such as politics, businesses, academics, social works, etc. Previous views about leadership show it as personal ability. The individual leader traits depend not only on personal abilities and his characteristics, but in special on the characteristics of the situation and environment in which he finds himself. People could become members of an organization in other to achieve certain personal objectives, the extent to which they are active members depends on how they are convinced that their membership will enable them to achieve their predetermined objectives. The leader will support an organization if he believes that through it his personal objectives and goals could be met otherwise the person’s interest will decline. The type leader or style of leading in an organization is one of the factors that play significant role in enhancing or retarding the interest and commitment of the individuals in the organization.

Leader charisma and affective team climate: the moderating role of the leader's influence and interaction.

2009-11-01

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

2001-01-01

To explore the influence of administrative aspects of a nutrition education program with peer educators delivering the program. Telephone interviews with peer educators trained to deliver La Cocina Saludable, a nutrition education program for Hispanics. Open- and closed-ended questions. Abuelas (grandmothers) recruited and trained as peer educators for the program. The sample included peer educators no longer teaching (22%), currently teaching (30%), and who never taught after training. Motives and incentives for becoming peer educators, challenges for peer educators, and reasons peer educators withdrew from the program. Descriptive statistics were used to analyze quantitative data from the closed-ended questions. Qualitative analysis was applied to data from open-ended questions. Working with community and learning about nutrition were prime motivators. Recruiting participants and coordination of classes appeared to be major challenges. Personal issues and traveling in a large geographic area were cited as the main reasons for quitting. The effectiveness of using peer educators for La Cocina Saludable may be improved through empowerment, additional training, a structured and equitable reimbursement system, and assistance to carry out administrative tasks.

Factors supporting dentist leaders' retention in leadership.

Tuononen, T; Lammintakanen, J; Suominen, A L

2017-12-01

The aim was to study factors associated with staying in a dentist leadership position. We used an electronic questionnaire to gather data from 156 current or former Finnish dentist leaders in 2014. Principal component analysis categorized statements regarding time usage and opportunities in managerial work into five main components. Associations between these main component scores and the tendency to stay as a leader were analyzed with logistic regression. Out of the five main components, two were significantly associated with staying as a leader: 'career intentions', which represented intent to continue or to leave the leadership position; and 'work time control opportunities', which represented how leaders could control their own work time. Other factors that supported staying were leadership education, more work time available for leadership work, and lower age. The main component 'work pressure' decreased, although not significantly, the odds of continuing; it included lack of leadership work time, and pressure from superiors or subordinates. Leaders have important roles in health care, ensuring everyday operations as well as developing their organizations to meet future challenges. Knowledge of these supporting factors will enable dentist leaders and their organizations to improve working conditions in order to recruit and retain motivated and competent persons. In addition, well-designed education is important to inspire and encourage future leaders. Copyright© 2017 Dennis Barber Ltd.

Peer pressure is regarded as an important determinant of substance use, sexual behavior and juvenile delinquency. However, few peer pressure scales are validated, especially in French or German. Little is known about the factor structure of such scales or the kind of scale needed: some scales takes into account both peer pressure to do and peer pressure not to do, while others consider only peer pressure to do. The aim of the present study was to adapt French and German versions of the Peer Pressure Inventory, which is one of the most widely used scales in this field. We considered its factor structure and concurrent validity. Five thousand eight hundred and sixty-seven young Swiss men filled in a questionnaire on peer pressure, substance use, and other variables (conformity, involvement) in a cohort study. We identified a four-factor structure, with the three factors of the initial Peer Pressure Inventory (involvement, conformity, misconduct) and adding a new one (relationship with girls). A non-valued scale (from no peer pressure to peer pressure to do only) showed stronger psychometric qualities than a valued scale (from peer pressure not to do to peer pressure to do). Concurrent validity was also good. Each behavior or attitude was significantly associated with peer pressure. Peer pressure seems to be a multidimensional concept. In this study, peer pressure to do showed the strongest influence on participants. Indeed, peer pressure not to do did not add anything useful. Only peer pressure to do affected young Swiss men's behaviors and attitudes and was reliable. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Simple Peer-to-Peer SIP Privacy

Science.gov (United States)

Koskela, Joakim; Tarkoma, Sasu

In this paper, we introduce a model for enhancing privacy in peer-to-peer communication systems. The model is based on data obfuscation, preventing intermediate nodes from tracking calls, while still utilizing the shared resources of the peer network. This increases security when moving between untrusted, limited and ad-hoc networks, when the user is forced to rely on peer-to-peer schemes. The model is evaluated using a Host Identity Protocol-based prototype on mobile devices, and is found to provide good privacy, especially when combined with a source address hiding scheme. The contribution of this paper is to present the model and results obtained from its use, including usability considerations.

Jupiter: Peer-to-Peer Networking Platform over Heterogeneous Networks

Directory of Open Access Journals (Sweden)

Norihiro Ishikawa

2006-10-01

Full Text Available Peer-to-peer has entered the public limelight over the last few years. Several research projects are underway on peer-to-peer technologies, but no definitive conclusion is currently available. Compared with traditional Internet technologies, peer-to-peer has the potential to realize highly scalable, extensible, and efficient distributed applications. This is because its basic functions realize resource discovery, resource sharing, and load balancing in a highly distributed manner. An easy prediction is the emergence of an environment in which many sensors, people, and many different kinds of objects exist, move, and communicate with one another. Peer-to-peer is one of the most important and suitable technologies for such networking since it supports discovery mechanisms, simple one-to-one communication between devices, free and extensible distribution of resources, and distributed search to handle the enormous number of resources. The purpose of this study is to explore a universal peer-to-peer network architecture that will allow various devices to communicate with one another across various networks. We have been designing architecture and protocols for realizing peer-to-peer networking among various devices. We are currently designing APIs that are available for various peer-to-peer applications and are implementing a prototype called "Jupiter" as a peer-to-peer networking platform over heterogeneous networks.

What about the leader? Crossover of emotional exhaustion and work engagement from followers to leaders.

Wirtz, Nina; Rigotti, Thomas; Otto, Kathleen; Loeb, Carina

2017-01-01

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

Brooks-Russell, Ashley; Foshee, Vangie; Ennett, Susan

2014-01-01

This study identified classes of developmental trajectories of physical dating violence victimization from grades 8 to 12 and examined theoretically-based risk factors that distinguished among trajectory classes. Data were from a multi-wave longitudinal study spanning 8th through 12th grade (n = 2,566; 51.9% female). Growth mixture models were used to identify trajectory classes of physical dating violence victimization separately for girls and boys. Logistic and multinomial logistic regressions were used to identify situational and target vulnerability factors associated with the trajectory classes. For girls, three trajectory classes were identified: a low/non-involved class; a moderate class where victimization increased slightly until the 10th grade and then decreased through the 12th grade; and a high class where victimization started at a higher level in the 8th grade, increased substantially until the 10th grade, and then decreased until the 12th grade. For males, two classes were identified: a low/non-involved class, and a victimized class where victimization increased slightly until the 9th grade, decreased until the 11th grade, and then increased again through the 12th grade. In bivariate analyses, almost all of the situational and target vulnerability risk factors distinguished the victimization classes from the non-involved classes. However, when all risk factors and control variables were in the model, alcohol use (a situational vulnerability) was the only factor that distinguished membership in the moderate trajectory class from the non-involved class for girls; anxiety and being victimized by peers (target vulnerability factors) were the factors that distinguished the high from the non-involved classes for the girls; and victimization by peers was the only factor distinguishing the victimized from the non-involved class for boys. These findings contribute to our understanding of the heterogeneity in physical dating violence victimization during

The aim of the present study is to describe and evaluate an ongoing peer-led model against bullying and cyberbullying carried out with Italian adolescents. The evaluation of the project was made through an experimental design consisting of a pre-test and a post-test. Participants in the study were 375 adolescents (20.3% males), enrolled in 9th to 13th grades. The experimental group involved 231 students with 42 peer educators, and the control group involved 144 students. Results showed a significant decrease in the experimental group as compared to the control group for all the variables except for cyberbullying. Besides, in the experimental group we found a significant increase in adaptive coping strategies like problem solving and a significant decrease in maladaptive coping strategies like avoidance: these changes mediate the changes in the behavioural variables. In particular, the decrease in avoidance predicts the decrease in victimization and cybervictimization for peer educators and for the other students in the experimental classes whereas the increase in problem solving predicts the decrease in cyberbullying only in the peer educators group. Results are discussed following recent reviews on evidence based efficacy of peer led models.

South African women who live in informal settlement communities are at high risk of HIV/AIDS infection due to their poor economic and social status. Prevention programs must include methods for improving their social conditions as well as their sexual risk behaviors. Members of Partners trained 24 women from informal settlements to lead HIV/AIDS education workshops for 480 residents. When these participants reached out to their neighbors, this participatory community-based approach resulted in providing HIV/AIDS prevention messages to more than 1,440 residents. Program leaders from three settlements said in focus group discussions that results from this social influences peer led approach demonstrated that women residents are a valuable resource in providing effective HIV/AIDS prevention programs to South Africa's most vulnerable residents.

To document peer teaching activity performed by first-year medical students and their views on the teaching activity. Survey. Medical Education Department, Ataturk University, Erzurum, Turkey, in the 2012 - 2013 academic year. Volunteer students were selected for peer teaching model by an academician from the Medical Education Department. Students were taught subjects selected from classes such as biochemistry and microbiology in the same way as the academicians do. Following each class activity, the teaching student was assessed by the other students on a 5-point rating scale. Written and verbal feedback was also obtained from both teaching students and participated students. Verbal feedbacks were noted by a faculty member and similar opinions were categorized. Data were analyzed by SPSS version 20 statistical program. Eleven students took part in the program. Feedback was received from students 171 times. The mean number of students participated was 24.4 ± 14.3 in each program. Statistical analysis revealed that mean value for teaching materials, peer instructors and teaching environment were 4.62 ± 0.49, 4.63 ± 0.47 and 3.88 ± 1. 27 respectively. Peer teaching method is a pretty good way of teaching for medical students. It is a practicable technique that can be used in medical training. Taking part in this program as a lecturer, student increased students' self-confidence in the learning and teaching activities. Quite positive feedbacks were received.

Barriers to undergraduate peer-physical examination of the lower limb in the health sciences and strategies to improve inclusion: a review.

Science.gov (United States)

Hendry, Gordon James

2013-10-01

Peer-physical examination is a widely adopted and an integral component of the undergraduate curriculum for many health science programs. Unwillingness or perceived inability to participate in peer-physical examination classes may have a negative impact upon students' abilities to competently conduct physical examinations of patients in future as registered health professionals. A literature review on the perceptions and attitudes of peer-physical examination of the lower limb amongst medical and health science students was conducted to identify potential barriers to participation, and to review strategies to improve participation in classes designed to develop clinical examination skills. A pragmatic search strategy of the literature from PubMed and Google Scholar published prior to June 2012 yielded 23 relevant articles. All articles were concerned with the views of medical students' education and there were no articles explicitly addressing the role of peer-physical examination in health science disciplines. Several ethical issues were identified including feelings of coercion, embarrassment, and perceptions of a lack of consideration for cultural and religious beliefs. The available evidence suggests that barriers to participation may be overcome by implementing standard protocols concerned with obtaining informed written consent, adequate choice of peer-examiner, changing facilities and garment advice, and possible alternative learning methods.

Leader-to-leader splicing is required for efficient production and accumulation of polyomavirus late mRNAs.

OpenAIRE

Adami, G R; Marlor, C W; Barrett, N L; Carmichael, G G

1989-01-01

Polyomavirus late mRNA molecules contain multiple, tandem copies of a noncoding 57-base "late leader" exon at their 5' ends. This exon is encoded only once in the genome. Leader multiplicity arises from leader-leader splicing in giant primary transcripts, which are the result of multiple circuits of the viral genome by RNA polymerase II. We have been interested in learning more about the role of the leader exon in late viral gene expression. We recently showed that an abbreviated-leader mutan...

2018-06-01

Full Text Available This review offers an integration of dark leadership styles with dark personality traits. The core of dark leadership consists of Three Nightmare Traits (TNT—leader dishonesty, leader disagreeableness, and leader carelessness—that are conceptualized as contextualized personality traits aligned with respectively (low honesty-humility, (low agreeableness, and (low conscientiousness. It is argued that the TNT, when combined with high extraversion and low emotionality, can have serious (“explosive” negative consequences for employees and their organizations. A Situation-Trait-Outcome Activation (STOA model is presented in which a description is offered of situations that are attractive to TNT leaders (situation activation, situations that activate TNT traits (trait activation, and the kinds of outcomes that may result from TNT behaviors (outcome activation. Subsequently, the TNT and STOA models are combined to offer a description of the organizational actions that may strengthen or weaken the TNT during six career stages: attraction, selection, socialization, production, promotion, and attrition. Except for mainly negative consequences of the TNT, possible positive consequences of TNT leadership are also explored, and an outline of a research program is offered that may provide answers to the most pressing questions in dark leadership research.

2016-05-01

The present study identifies and describes romantic relationship patterns from adolescence to adulthood and examines their associations with family and peer experiences in early adolescence. In a 13-year longitudinal study, 281 youth (58 % girls) identified all their romantic partners each year from the ages of 16-24. Dimensions of family relationships (family cohesion, parent-child conflict) and peer relationships (peer likeability, social withdrawal, close friendships, other-sex friendships) were assessed at age 12. Latent class analyses brought out five distinct romantic relationship patterns and significant associations were found with family and peer relationships in early adolescence. These five romantic relationship patterns appeared to follow a continuum of romantic involvement, with romantic relationship patterns situated a both ends of this continuum (later involvement pattern and intense involvement pattern) being associated with more interpersonal experiences in early adolescence.

In this study, the robustness of the Big Five personality factors in adolescents' self-ratings and peer nominations was investigated. Data were obtained on 2,001 adolescents attending secondary school (885 girls; 1,116 boys; M age = 14.5 years). Exploratory and confirmatory factor analyses on the self-ratings confirmed the Big Five personality factors. In contrast, exploratory analysis on the peer nominations revealed five different factors: Aggression-Inattentiveness, Achievement-Withdrawal, Self-Confidence, Sociability, and Emotionality-Nervousness. It is suggested that peers evaluate group members not in terms of their personality but in terms of their group reputation. Peer evaluations contributed substantially to the prediction of peer acceptance and rejection; the Big Five personality factors based on self-ratings did not.

Do lightning positive leaders really "step"?

Science.gov (United States)

Petersen, D.

2015-12-01

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

Cultures differ in the emotions they teach their members to value ("ideal affect"). We conducted 3 studies to examine whether leaders' smiles reflect these cultural differences in ideal affect. In Study 1, we compared the smiles of top-ranked American and Chinese government leaders, chief executive officers, and university presidents in their official photos. Consistent with findings that Americans value excitement and other high-arousal positive states more than Chinese, American top-ranked leaders (N = 98) showed more excited smiles than Chinese top-ranked leaders (N = 91) across occupations. In Study 2, we compared the smiles of winning versus losing political candidates and higher versus lower ranking chief executive officers and university presidents in the United States and Taiwan/China. American leaders (N = 223) showed more excited smiles than Taiwanese/Chinese leaders (N = 266), regardless of election outcome or ranking. In Study 3, we administered self-report measures of ideal affect in college student samples from 10 different nations (N = 1,267) and then 8 years later, coded the smiles that legislators from those nations showed in their official photos (N = 3,372). The more nations valued excitement and other high arousal positive states, the more their leaders showed excited smiles; similarly, the more nations valued calm and other low-arousal positive states, the more their leaders showed calm smiles. These results held after controlling for national differences in democratization, human development, and gross domestic product per capita. Together, these findings suggest that leaders' smiles reflect the affective states valued by their cultures. (c) 2016 APA, all rights reserved).

Peer review in design: Understanding the impact of collaboration on the review process and student perception

Science.gov (United States)

Mandala, Mahender Arjun

A cornerstone of design and design education is frequent situated feedback. With increasing class sizes, and shrinking financial and human resources, providing rich feedback to students becomes increasingly difficult. In the field of writing, web-based peer review--the process of utilizing equal status learners within a class to provide feedback to each other on their work using networked computing systems--has been shown to be a reliable and valid source of feedback in addition to improving student learning. Designers communicate in myriad ways, using the many languages of design and combining visual and descriptive information. This complex discourse of design intent makes peer reviews by design students ambiguous and often not helpful to the receivers of this feedback. Furthermore, engaging students in the review process itself is often difficult. Teams can complement individual diversity and may assist novice designers collectively resolve complex task. However, teams often incur production losses and may be impacted by individual biases. In the current work, we look at utilizing a collaborative team of reviewers, working collectively and synchronously, in generating web based peer reviews in a sophomore engineering design class. Students participated in a cross-over design, conducting peer reviews as individuals and collaborative teams in parallel sequences. Raters coded the feedback generated on the basis of their appropriateness and accuracy. Self-report surveys and passive observation of teams conducting reviews captured student opinion on the process, its value, and the contrasting experience they had conducting team and individual reviews. We found team reviews generated better quality feedback in comparison to individual reviews. Furthermore, students preferred conducting reviews in teams, finding the process 'fun' and engaging. We observed several learning benefits of using collaboration in reviewing including improved understanding of the assessment

The use of student tutors (peers) is an accepted method in medical education. In 2011, final year students of the otorhinolaryngology (ORL) department of the University Hospital in Dresden were appointed as peers for the clinical ORL examination. They assisted in the instruction of the clinical ORL examination (peer teaching, PT) and served as examiners (peer assessment, PA) in the final objective structured clinical examination (OSCE). The effect on the quality of education and examination was examined. 248 medical students (5(th) year) were divided in 2 groups. They were trained and finally examined in the standardized clinical ORL examination by peers and/or physicians. Group I (n=118) was exclusively trained and examined by physicians and group II (n=130) by peers and physicians. The results of the OSCE were stratified for the 2 groups and in group II for the subgroups according to the instructors' and examiners' qualification (peer or physician). The students evaluated the internship and the instructors' and examiners' quality with a validated questionnaire. In the OSCE, group I scored in the mean 59.9±4.9 points (max. 65). In group II the mean score was 58.3±4.3 points examined by the peers and 59.5±4.8 points for same performance assessed by the physicians. There were no statistical significant differences in the examination results when stratified for the instructors' and examiners' qualification. The evaluation results were consistently positive and identical when compared to the previous year without use of PT and PA and between the 2 groups and subgroups. When using a standardized clinical examination routine peers can be used for PT and PA to appropriate tools in student's medical education without any decrease in the teaching and examination quality. © Georg Thieme Verlag KG Stuttgart · New York.

In praise of the incomplete leader.

Today's top executives are expected to do everything right, from coming up with solutions to unfathomably complex problems to having the charisma and prescience to rally stakeholders around a perfect vision of the future. But no one leader can be all things to all people. It's time to end the myth of the complete leader, say the authors. Those at the top must come to understand their weaknesses as well as their strengths. Only by embracing the ways in which they are incomplete can leaders fill in the gaps in their knowledge with others' skills. The incomplete leader has the confidence and humility to recognize unique talents and perspectives throughout the organization--and to let those qualities shine. The authors' work studying leadership over the past six years has led them to develop a framework of distributed leadership. Within that model, leadership consists of four capabilities: sensemaking, relating, "visioning," and inventing. Sensemaking involves understanding and mapping the context in which a company and its people operate. A leader skilled in this area can quickly identify the complexities of a given situation and explain them to others. The second capability, relating, means being able to build trusting relationships with others through inquiring (listening with intention), advocating (explaining one's own point of view), and connecting (establishing a network of allies who can help a leader accomplish his or her goals). Visioning, the third capability, means coming up with a compelling image of the future. It is a collaborative process that articulates what the members of an organization want to create. Finally, inventing involves developing new ways to bring that vision to life. Rarely will a single person be skilled in all four areas. That's why it's critical that leaders find others who can offset their limitations and complement their strengths. Those who don't will not only bear the burden of leadership alone but will find themselves at the helm

This study evaluated the effectiveness of a community health worker (CHW) diabetes self-management education (DSME) program, followed by two different approaches to maintain improvements in HbA 1c and other clinical and patient-centered outcomes over 18 months. The study randomized 222 Latino adults with type 2 diabetes and poor glycemic control from a federally qualified health center to 1 ) a CHW-led, 6-month DSME program or 2 ) enhanced usual care (EUC). After the 6-month program, participants randomized to the CHW-led DSME were further randomized to 1 ) 12 months of CHW-delivered monthly telephone outreach (CHW-only) or 2 ) 12 months of weekly group sessions delivered by peer leaders (PLs) with telephone outreach to those unable to attend (CHW+PL). The primary outcome was HbA 1c . Secondary outcomes were blood pressure, lipid levels, diabetes distress, depressive symptoms, understanding of diabetes self-management, and diabetes social support. Assessments were conducted at baseline and at 6, 12, and 18 months. Participants in the CHW intervention at the 6-month follow-up had greater decreases in HbA 1c (-0.45; 95% CI -0.87, -0.03; P diabetes distress (-0.3; 95% CI -0.6, -0.03; P diabetes distress at 12 and 18 months. CHW+PL participants also had significantly fewer depressive symptoms at 18 months compared with EUC (-2.2; 95% CI -4.1, -0.3; P diabetes social support and in understanding of diabetes self-management at 6 months relative to EUC, but these intervention effects were not sustained at 18 months. This study demonstrates the effectiveness of a 6-month CHW intervention on key diabetes outcomes and of a volunteer PL program in sustaining key achieved gains. These are scalable models for health care centers in low-resource settings for achieving and maintaining improvements in key diabetes outcomes. © 2018 by the American Diabetes Association.

School climate and bullying victimization: a latent class growth model analysis.

Gage, Nicholas A; Prykanowski, Debra A; Larson, Alvin

2014-09-01

Researchers investigating school-level approaches for bullying prevention are beginning to discuss and target school climate as a construct that (a) may predict prevalence and (b) be an avenue for school-wide intervention efforts (i.e., increasing positive school climate). Although promising, research has not fully examined and established the social-ecological link between school climate factors and bullying/peer aggression. To address this gap, we examined the association between school climate factors and bullying victimization for 4,742 students in Grades 3-12 across 3 school years in a large, very diverse urban school district using latent class growth modeling. Across 3 different models (elementary, secondary, and transition to middle school), a 3-class model was identified, which included students at high-risk for bullying victimization. Results indicated that, for all students, respect for diversity and student differences (e.g., racial diversity) predicted within-class decreases in reports of bullying. High-risk elementary students reported that adult support in school was a significant predictor of within-class reduction of bullying, and high-risk secondary students report peer support as a significant predictor of within-class reduction of bullying.

First and foremost, physicians: the clinical versus leadership identities of physician leaders.

Science.gov (United States)

Quinn, Joann Farrell; Perelli, Sheri

2016-06-20

Purpose - Physicians are commonly promoted into administrative and managerial roles in US hospitals on the basis of clinical expertise and often lack the skills, training or inclination to lead. Several studies have sought to identify factors associated with effective physician leadership, yet we know little about how physician leaders themselves construe their roles. The paper aims to discuss these issues. Design/methodology/approach - Phenomenological interviews were performed with 25 physicians at three organizational levels with physicians affiliated or employed by four hospitals within one health care organization in the USA between August and September 2010. A rigorous comparative methodology of data collection and analysis was employed, including the construction of analytic codes for the data and its categorization based on emergent ideas and themes that are not preconceived and logically deduced hypotheses, which is characteristic of grounded theory. Findings - These interviews reveal differences in how part- vs full-time physician leaders understand and value leadership roles vs clinical roles, claim leadership status, and identify as physician leaders on individual, relational and organizational basis. Research limitations/implications - Although the physicians in the sample were affiliated with four community hospitals, all of them were part of a single not-for-profit health care system in one geographical locale. Practical implications - These findings may be of interest to hospital administrators and boards seeking deeper commitment and higher performance from physician leaders, as well as assist physicians in transitioning into a leadership role. Social implications - This work points to a broader and more fundamental need - a modified mindset about the nature and value of physician leadership. Originality/value - This study is unique in the exploration of the nature of physician leadership from the perspective of the physician on an individual, peer

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

Finding pertinent information is not limited to search engines. Online communities can amplify the influence of a small number of power users for the benefit of all other users. Users' information foraging in depth and breadth can be greatly enhanced by choosing suitable leaders. For instance in delicious.com, users subscribe to leaders' collection which lead to a deeper and wider reach not achievable with search engines. To consolidate such collective search, it is essential to utilize the leadership topology and identify influential users. Google's PageRank, as a successful search algorithm in the World Wide Web, turns out to be less effective in networks of people. We thus devise an adaptive and parameter-free algorithm, the LeaderRank, to quantify user influence. We show that LeaderRank outperforms PageRank in terms of ranking effectiveness, as well as robustness against manipulations and noisy data. These results suggest that leaders who are aware of their clout may reinforce the development of social networks, and thus the power of collective search.

We investigate various aspects of the statistics of leaders in growing network models defined by stochastic attachment rules. The leader is the node with highest degree at a given time (or the node which reached that degree first if there are co-leaders). This comprehensive study includes the full distribution of the degree of the leader, its identity, the number of co-leaders, as well as several observables characterizing the whole history of lead changes: number of lead changes, number of distinct leaders, lead persistence probability. We successively consider the following network models: uniform attachment, linear attachment (the Barabási–Albert model), and generalized preferential attachment with initial attractiveness

Objective The development and course of the subtypes of peer victimization is a relatively understudied topic despite the association of victimization with important developmental and clinical outcomes. Moreover, understanding potential predictors, such as peer rejection and emotion regulation, in early childhood may be especially important to elucidate possible bi-directional pathways between relational and physical victimization and rejection. The current study (N = 97) was designed to explore several gaps and limitations in the peer victimization and peer rejection literature. In particular, the prospective associations between relational and physical victimization and peer rejection over the course of 3.5 months during early childhood (i.e., 3- to 5- years-old) were investigated in an integrated model. Method The study consisted of 97 (42 girls) preschool children recruited from four early childhood schools in the northeast of the US. Using observations, research assistant report and teacher report, relational and physical aggression, relational and physical victimization, peer rejection, and emotion regulation were measured in a short-term longitudinal study. Path analyses were conducted to test the overall hypothesized model. Results Peer rejection was found to predict increases in relational victimization. In addition, emotion regulation was found to predict decreases in peer rejection and physical victimization. Conclusions Implications for research and practice are discussed, including teaching coping strategies for peer rejection and emotional distress. PMID:25133659

Despite advances in tobacco control, adolescent smoking remains a problem. The smoking status of friends is one of the highest correlates with adolescent smoking. This homophily (commonality of friends based on a given attribute) may be due to either peer pressure, where adolescents adopt the smoking behaviors of their friends, or peer selection, where adolescents choose friends based on their smoking status. This study used structural equation modeling to test a model of peer influence and peer selection on ever smoking by adolescents. The primary analysis of the model did not reach significance, but post hoc analyses did result in a model with good fit. Results indicated that both peer influence and peer selection were occurring, and that peer influence was more salient in the population than was peer selection. Implications of these results for tobacco prevention programs are discussed.

Peer Learning in Instrumental Practicing.

Nielsen, Siw G; Johansen, Guro G; Jørgensen, Harald

2018-01-01

In higher music education (HME), the notion of "private teaching, private learning" has a long tradition, where the learning part rests on the student's individual practicing between instrumental lessons. However, recent research suggests that collaborative learning among peers is beneficial in several aspects, such as sense of belonging, motivation and self-efficacy. This is consistent with the concept of vicarious learning. In this study, we conducted a survey among bachelor music students in church music, performance or music education programs enrolled in a music academy ( N = 96), where parts of the questionnaire addressed peer learning and peer's influence on the students's instrumental practicing, and the degree of satisfaction with their practicing. These issues were seen in relation to gender, musical genre and study program. Overall, the students reported engaging in peer learning related to their instrumental practicing, to various degrees. This involved discussing practicing matters with peers, and practicing together with peers. However, student's reports of their views on peer learning, show that they perceive it more beneficial than the amount of time reported doing it would indicate. No significant gender differences were found, but students within improvised music/jazz engaged the most in peer learning, and church music students the least. Neither the degree of engaging in peer learning nor reported influence from peers correlated significantly with the degree of satisfaction. We discuss whether a general dissatisfaction is caused by being in a competitive learning environment combined with a privatized culture for learning. Finally, we suggest that collaborative forums for instrumental practicing within HME institutions can function as constructive and supportive arenas to enhance students learning and inner motivation.

How Mandated College Students Talk About Alcohol: Peer Communication Factors Associated with Drinking

Science.gov (United States)

Carey, Kate B.; Lust, Sarah A.; Reid, Allecia E.; Kalichman, Seth C.; Carey, Michael P.

2015-01-01

Relatively little research has examined how peer communication influences alcohol consumption. In a sample of mandated college students, we differentiate conversations about drinking among from conversations about harm prevention and provide evidence for the validity of these communication constructs. Students who violated campus alcohol policies and were referred for alcohol sanctions (N = 345) reported on drinking patterns, use of protective behavioral strategies, perceived descriptive norms for close friends and serving as social leader among their friends; they also reported on the frequency of conversations about drinking, about drinking safety, and about risk reduction efforts. Predicted correlations were found among types of communication and conceptually related variables. General communication was related to consumption but not protective behavioral strategies, whereas safety/risk reduction conversations correlated positively with all protective behavioral strategies. Both types of communication were associated with social leadership. Safety communication moderated the relationship between peer descriptive norms and drinks per week; more frequent talking about safety attenuated the norms-consumption relationship. Peer communication about both drinking and safety may serve as targets for change in risk reduction interventions for mandated college students. PMID:26861808

Williams, Quintin; Ochsner, Michele; Marshall, Elizabeth; Kimmel, Louis; Martino, Carmen

2010-06-01

workers surveyed post-training reported sharing information from their safety workbook with friends and co-workers. Focus groups and interview results generally confirmed the quantitative findings. Participatory, peer led training tailored to the needs of construction day laborers may have a positive effect on Latino immigrant workers' attitudes, work practices, and self reported injury rates, but major changes would require employer engagement. Health and safety researchers have identified reducing the number of traumatic injuries among the immigrant construction workforce as an increasingly important priority. This project provides one model for collaboration between university-based researchers, a union, and a community-based organization. The specific elements of this project-participatory curriculum customized to the needs of day laborers in residential construction, training day laborers to facilitate training classes, and involving peer leaders in outreach and research-could be adapted by other organizations. The findings of this study suggest that the Latino day laborers have a strong interest in and some ability to act on health and safety information. Widespread implementation of this type of training, especially if supported with cooperation from residential contractors, could lead to reduced rates of traumatic injury in the residential construction industry.

My beliefs of my peers' beliefs: exploring the gendered nature of social norms in adolescent romantic relationships.

Science.gov (United States)

Hertzog, Jodie L; Rowley, Rochelle Lynn

2014-01-01

Dating violence in adolescent relationships is a growing social problem in the United States. A majority of adolescents have dated by the time they finish high school and these experiences have an impact on their relationship trajectories as adults. Although more and more prevention efforts are aimed at reducing teen dating violence and/or teaching adolescents about healthy relationships, very few of these efforts investigate discrepancies in descriptive and injunctive norms associated with adolescent dating. This pilot study adds to the existing literature by investigating the dating norms of early and mid-adolescents to aid in tailoring prevention efforts among this population. One hundred eighty-seven middle and high school student leaders from public schools in the Midwest completed an annual relationship survey. Findings suggest that participants did not support unhealthy relationship norms overall. However, two patterns of discrepancies emerged: one between participant attitudes (descriptive norms) and their perceptions of peer attitudes (injunctive norms), and another between perceptions participants hold about their male versus female peers' beliefs. Results imply the development of pluralistic ignorance occurs during adolescence and that perceptions of peer norms are in line with the principles of hegemonic masculinity. Implications for possible prevention initiatives and future research directions are noted.

Social Consequences of Academic Teaming in Middle School: The Influence of Shared Course-Taking on Peer Victimization

Science.gov (United States)

Echols, Leslie

2014-01-01

This study examined the influence of academic teaming (i.e., sharing academic classes with the same classmates) on the relationship between social preference and peer victimization among 6th grade students in middle school. Approximately 1,000 participants were drawn from 5 middle schools that varied in their practice of academic teaming. A novel methodology for measuring academic teaming at the individual level was employed, in which students received their own teaming score based on the unique set of classmates with whom they shared academic courses in their class schedule. Using both peer- and self-reports of victimization, the results of two path models indicated that students with low social preference in highly teamed classroom environments were more victimized than low preference students who experienced less teaming throughout the school day. This effect was exaggerated in higher performing classrooms. Implications for the practice of academic teaming were discussed. PMID:25937668

2015-01-01

In response to calls for implementing active learning in college-level science, technology, engineering, and mathematics courses, classrooms across the country are being transformed from instructor centered to student centered. In these active-learning classrooms, the dynamics among students becomes increasingly important for understanding student experiences. In this study, we focus on the role a student prefers to assume during peer discussions, and how this preferred role may vary given a student’s social identities. In addition we explore whether three hypothesized barriers to participation may help explain participation difference in the classroom. These barriers are 1) students are excluded from the discussion by actions of their groupmates; 2) students are anxious about participating in peer discussion; and 3) students do not see value in peer discussions. Our results indicate that self-reported preferred roles in peer discussions can be predicted by student gender, race/ethnicity, and nationality. In addition, we found evidence for all three barriers, although some barriers were more salient for certain students than others. We encourage instructors to consider structuring their in-class activities in ways that promote equity, which may require more purposeful attention to alleviating the current differential student experiences with peer discussions.

Lewis, Adam; Cave, Phoene; Hopkinson, Nicholas S

2017-01-01

Introduction Singing for Lung Health (SLH) groups are an increasingly popular intervention for people with respiratory disease. There are limited data as to how these groups should be developed and run. We aimed to evaluate the experience of singing leaders both to assess the training provided by the British Lung Foundation (BLF) and to provide information to guide future development of programmes. Methods A convenience sample of 15 leaders who had received BLF SLH training participated in the BLF service evaluation. Fifteen singing groups were observed, and singing leader interviews and questionnaires were collected. Inductive themes from the qualitative data were the primary outcome. The content of observed singing groups was also rated against the training leaders had received. Results Singing leaders valued the BLF training but felt that a significant level of expertise is required before joining. Singing leaders often found setting up groups challenging and some found clinician support beneficial. There were important technical aspects of running a lung health group including issues around content, for example, choice of repertoire to suit breathing pattern, and delivery, for example, pace, rhythm and management of group dynamics. Leaders said that group participants reported physical health improvements such as reduced breathlessness on activity. The content and delivery of singing classes observed displayed a good level of fidelity, suggesting that SLH training is effective. Conclusion The experience of the leaders highlights the requirements, support and technical skills needed to run SLH groups, which have features distinct from generic community singing groups.

Peer-to-peer psychological contracts in the South African wine industry

Directory of Open Access Journals (Sweden)

Ruth Penfold

2015-12-01

Full Text Available Orientation: Very few studies examine the impact of peer relationships on the psychological contract. Research purpose: Using the backdrop of wine farm workers in the Western Cape, South Africa, the aim of our study was to explore the nature of peer relationships shaping the psychological contract. Motivation for the study: The agricultural sector of South Africa, in particular the wine farms in the Western Cape, has undergone radical change in the past decades as a result of labour legislation and changing government structures. It was therefore expected that these changes would influence the psychological contracts held by wine farm workers. Research approach, design and method: This qualitative study sampled all 24 full-time employees and 2 managers on the Constantia Hills Wine Estate in Cape Town, South Africa. Semi-structured interviews were conducted using the critical incident technique in combination with a series of open questions. Main findings: Our findings showed support for the existence of peer-to-peer psychological contracts and noted the valuable influence of a suitable conduit individual on the relationship between employees and their employer. Practical and/or managerial implications: Wine farm workers in South Africa have a strong need to be consulted after a lifetime of having no voice. In addition to ensuring suitable levels of two-way communication, management must understand the inter-peer contract and the nature of the relationships sustaining it. Contribution: Whilst literature has suggested that management of the psychological contract lies firmly within the domain of the employer, our findings indicated that ensuring harmonious peer-to-peer contracts was also central to good working relationships.

Wealth and the inflated self: class, entitlement, and narcissism.

Science.gov (United States)

Piff, Paul K

2014-01-01

Americans may be more narcissistic now than ever, but narcissism is not evenly distributed across social strata. Five studies demonstrated that higher social class is associated with increased entitlement and narcissism. Upper-class individuals reported greater psychological entitlement (Studies 1a, 1b, and 2) and narcissistic personality tendencies (Study 2), and they were more likely to behave in a narcissistic fashion by opting to look at themselves in a mirror (Study 3). Finally, inducing egalitarian values in upper-class participants decreased their narcissism to a level on par with their lower-class peers (Study 4). These findings offer novel evidence regarding the influence of social class on the self and highlight the importance of social stratification to understanding basic psychological processes.

The condition for mutual, or peer-to-peer, locking of two magnetrons is derived. This condition reduces to Adler's classical phase-locking condition in the limit where one magnetron becomes the ''master'' and the other becomes the ''slave.'' The formulation is extended to the peer-to-peer locking of N magnetrons, under the assumption that the electromagnetic coupling among the N magnetrons is modeled by an N-port network.

Iudin, Dmitry; Syssoev, Artem; Davydenko, Stanislav; Rakov, Vladimir

2017-04-01

It is well-known that the negative leaders develop in a step manner using a mechanism of the so-called space leaders in contrary to positive ones, which propagate continuously. Despite this fact has been known for about a hundred years till now no one had developed any plausible model explaining this asymmetry. In this study we suggest a model of the stepped development of the negative lightning leader which for the first time allows carrying out the numerical simulation of its evolution. The model is based on the probability approach and description of temporal evolution of the discharge channels. One of the key features of our model is accounting for the presence of so called space streamers/leaders which play a fundamental role in the formation of negative leader's steps. Their appearance becomes possible due to the accounting of potential influence of the space charge injected into the discharge gap by the streamer corona. The model takes into account an asymmetry of properties of negative and positive streamers which is based on well-known from numerous laboratory measurements fact that positive streamers need about twice weaker electric field to appear and propagate as compared to negative ones. An extinction of the conducting channel as a possible way of its evolution is also taken into account. This allows us to describe the leader channel's sheath formation. To verify the morphology and characteristics of the model discharge, we use the results of the high-speed video observations of natural negative stepped leaders. We can conclude that the key properties of the model and natural negative leaders are very similar.

Effective peer-to-peer support for young people with end-stage renal disease: a mixed methods evaluation of Camp COOL

Background The Camp COOL programme aims to help young Dutch people with end-stage renal disease (ESRD) develop self-management skills. Fellow patients already treated in adult care (hereafter referred to as ‘buddies’) organise the day-to-day program, run the camp, counsel the attendees, and also participate in the activities. The attendees are young people who still have to transfer to adult care. This study aimed to explore the effects of this specific form of peer-to-peer support on the self-management of young people (16–25 years) with ESRD who participated in Camp COOL (CC) (hereafter referred to as ‘participants’). Methods A mixed methods research design was employed. Semi-structured interviews (n = 19) with initiators/staff, participants, and healthcare professionals were conducted. These were combined with retrospective and pre-post surveys among participants (n = 62), and observations during two camp weeks. Results Self-reported effects of participants were: increased self-confidence, more disease-related knowledge, feeling capable of being more responsible and open towards others, and daring to stand up for yourself. According to participants, being a buddy or having one positively affected them. Self-efficacy of attendees and independence of buddies increased, while attendees’ sense of social inclusion decreased (measured as domains of health-related quality of life). The buddy role was a pro-active combination of being supervisor, advisor, and leader. Conclusions Camp COOL allowed young people to support each other in adjusting to everyday life with ESRD. Participating in the camp positively influenced self-management in this group. Peer-to-peer support through buddies was much appreciated. Support from young adults was not only beneficial for adolescent attendees, but also for young adult buddies. Paediatric nephrologists are encouraged to refer patients to CC and to facilitate such initiatives. Together with nephrologists in adult

An audience response system (ARS) has become popular among educators in medicine and the health professions because of the system's ability to engage listeners during a lecture presentation. No one has described the usefulness of ARS technology during planned nonlecture peer teaching sessions in gross anatomy instruction for health professionals. The unique feature of each peer teaching session was a nongraded 12-15 item ARS quiz assembled by six second-year doctor of physical therapy (DPT) students and purposely placed at the beginning of the review session for those first-year DPT students in attendance. This study used a ten-item questionnaire and a five-point Likert scale in addition to three open ended questions to survey perceptions of both first-year and second-year DPT students about the usefulness of ARS technology implemented during weekly interactive peer teaching sessions during a semester course in Anatomy for Physical Therapists. First-year students overwhelmingly acknowledged the ARS system permitted each student to self-assess his/her preparedness for a quiz or examination and compare his/her performance with that of classmates. Peer teachers recognized an ARS quiz provided them an opportunity to: (1) estimate first-year students' level of understanding of anatomical concepts; and (2) effectively prepare first-year students for their weekly quizzes and future examinations. On the basis of the mutual benefits derived by both students/tutees and teachers/tutors, physical therapist educators may wish to consider using ARS technology to enhance teaching methods for a class in gross human anatomy.

Auctioning emission permits in a leader-follower setting

We analise emission permit auctions under leader-follower competition when the leader bids strategically and the follower acts as price-taker both at the auction and the secondary market. We obtain linear equilibrium bidding strategies for both firms and a unique equilibrium of the auction, which is optimal ex-post for the leader. Under specific distributional assumptions we conclude that the auction always awards less permits to the leader than the cost-effective amount. Our central result i...
