Peer influence in NIPF landowner decision making in the western Upper Peninsula, Michigan

Non-industrial private forest (NIPF) owners hold the largest amount of privately owned forest in the United States. Activities undertaken by NIPF owners have the potential to drastically impact the forested landscape of the United States, along with its associated biodiversity and ecological services. Many government sanctioned programs are in place to discourage the conversion of forest to other uses as well as to ensure sustainable management and a continuous supply of timber. Reaching NIPF owners with information about these programs and other management information is therefore important to the forests of the United States. This thesis presents research on how the NIPF owners of the western Upper Peninsula of Michigan communicate about forest management with neighboring NIPF owners. The data were obtained from 34 telephone interviews with owners of NIPF properties in the western Upper Peninsula. The goal of this research was to understand the way information moves through NIPF owner dominated landscapes in order to provide recommendations to policy implementers on how to best reach NIPF owners with information. Understanding where NIPF owners get information about management and landowner assistance programs is vital to ensuring a sustainably managed forest landscape in the western Upper Peninsula of Michigan.

Emergence of Financial Intermediaries in Electronic Markets: The Case of Online P2P Lending

We analyze the role of intermediaries in electronic markets using detailed data of more than 14,000 originated loans on an electronic P2P (peer-to-peer) lending platform. In such an electronic credit market, lenders bid to supply a private loan. Screening of potential borrowers and the monitoring of loan repayment can be delegated to designated group leaders. We find that these market participants act as financial intermediaries and significantly improve borrowers' credit conditions by reducing information asymmetries, predominantly for borrowers with less attractive risk characteristics. Our findings may be surprising given the replacement of a bank by an electronic marketplace.

Peer victimisation and depressive symptoms: can specific coping strategies buffer the negative impact of cybervictimisation?

This longitudinal study investigated whether cybervictimisation is an additional risk factor for depressive symptoms over and beyond traditional victimisation in adolescents. Furthermore, it explored whether certain coping strategies moderate the impact of cybervictimisation on depressive symptoms. A total of 765 Swiss seventh graders (mean age at time-point 1 (t1) = 13.18 years) reported on the frequency of traditional and cybervictimisation, and of depressive symptoms twice in six months. At time-point 2 (t2) students also completed a questionnaire on coping strategies in response to a hypothetical cyberbullying scenario. Analyses showed that both traditional and cybervictimisation were associated with higher levels of depressive symptoms. Cybervictimisation also predicted increases in depressive symptoms over time. Regarding coping strategies, it was found that helpless reactions were positively associated with depressive symptoms. Moreover, support seeking from peers and family showed a significant buffering effect: cybervictims who recommended seeking close support showed lower levels of depressive symptoms at t2. In contrast, cybervictims recommending assertive coping strategies showed higher levels of depressive symptoms at t2.

Characteristics and experiences of past participants in the Texas Peer Assistance Program for Nurses

There are nearly 200,000 licensed practicing nurses in the state of Texas, representing one-tenth of the nations' workforce. The prevalence of substance abuse among nurses is estimated to range between six and 20 percent in this professional group.^ Since March 1987, the Texas Peer Assistance Program for Nurses (TPAPN) has offered intervention, education, support and monitoring to nurses in Texas whose practice has become impaired due to substance abuse and/or mental illness. Since then approximately 44 percent of nurses who voluntarily signed participation agreements successfully completed the program; fifty-six percent have not. One determinant of completion for those nurses identified as chemically dependent is abstinence from mood altering substances. Other helping professions report higher rates of abstinence two years following treatment.^ The purpose of this study was to investigate the relationship between relapse, demographics, treatment variables, work setting, "stress" indicators and support factors for nurses who participated in TPAPN. A questionnaire was mailed to 1000 randomly selected nurses who had signed agreements since 1987 and were no longer active in the program. More than 41% of the questionnaires were returned undeliverable.^ Recipients of the questionnaire were known only to TPAPN, never to the investigator. All information was received anonymously except when the participant chose to sign the questionnaire. A cover letter explaining the study and inviting participation was enclosed. Completion and return of the questionnaire was considered consent to participate.^ Findings demonstrated a significant relationship between relapse and opiates as the drug of choice for past participants in the Texas Peer Assistance Program for Nurses. Significant associations were found among factors such as control at work, support, physical complaints, job security, self-esteem and employment in this sample. Respondents shared copious written comments about their experiences in TPAPN. These data were analyzed using qualitative methods and compared with similar studies of recovering nurses. Further research with nurses whose practice has been affected by abuse of chemical and mental illness is warranted. ^

Cost-effectiveness of peer role play and standardized patients in undergraduate communication training.

BACKGROUND The few studies directly comparing the methodological approach of peer role play (RP) and standardized patients (SP) for the delivery of communication skills all suggest that both methods are effective. In this study we calculated the costs of both methods (given comparable outcomes) and are the first to generate a differential cost-effectiveness analysis of both methods. METHODS Medical students in their prefinal year were randomly assigned to one of two groups receiving communication training in Pediatrics either with RP (N = 34) or 19 individually trained SP (N = 35). In an OSCE with standardized patients using the Calgary-Cambridge Referenced Observation Guide both groups achieved comparable high scores (results published). In this study, corresponding costs were assessed as man-hours resulting from hours of work of SP and tutors. A cost-effectiveness analysis was performed. RESULTS Cost-effectiveness analysis revealed a major advantage for RP as compared to SP (112 vs. 172 man hours; cost effectiveness ratio .74 vs. .45) at comparable performance levels after training with both methods. CONCLUSIONS While both peer role play and training with standardized patients have their value in medical curricula, RP has a major advantage in terms of cost-effectiveness. This could be taken into account in future decisions.

Peer Acceptance and Friendship as Predictors of Early Adolescents' Adjustment Across the Middle School Transition

This study examines several aspects of adolescents' pretransition peer relationships as predictors of their adjustment to middle school. Participants were 365 students (175 boys; 99% Caucasian) involved in the Time 1 (the spring of fifth grade) and Time 2 (the fall of sixth grade) assessments. Adolescents completed measures that assessed peer acceptance, number of friends, the quality of a specific mutual friendship, loneliness, depression, self-esteem, and involvement in school. Academic achievement and absentee data were obtained from student files. Regression analyses indicated that the pretransition peer variables predicted posttransition loneliness, self-esteem, school involvement, and academic achievement. The patterns of prediction varied slightly for each adjustment variable, with the most robust relationship being between peer acceptance and achievement. Results of repeated-measures MANOVAs indicated no differential changes in adjustment across time by gender. Implications for including a peer component in programs that prepare students for the middle school transition are discussed.

PARENT-CHILD RELATIONSHIP QUALITY AND THE INFLUENCE ON SOCIOMETRIC VERSUS PEER-PERCEIVED POPULARITY

The purpose of this study was to compare factors in the parent-child relationships of peer perceived popular adolescents to those of sociometrically popular adolescents. Factors included autonomy, relatedness, and idealization. Participants were 71 8th grade adolescents. Results showed similarities in parent-child relationships between perceived popular and sociometrically popular adolescents for autonomy, relatedness, and idealization. Results suggest that future research should explore other factors, such as affection from mother and father and levels of psychological control behavior to differentiate perceived popularity from sociometrically popular adolescents.

An analysis of the effects of a peer mentor program and other factors on HIV patients' retention in care and clinical outcomes at Thomas Street Health Clinic, Houston Texas

Research examining programs designed to retain patients in health care focus on repeated interactions between outreach workers and patients (Bradford et al. 2007; Cheever 2007). The purpose of this study was to determine if patients who are peer-mentored at their intake exam remain in care longer and attend more physicians' visits than those who were not mentored. Using patients' medical records and a previously created mentor database, the study determined how many patients attended their intake visit but subsequently failed to establish regular care. The cohort study examined risk factors for establishing care, determined if patients lacking a peer mentor failed to establish care more than peer mentor assisted patients, and subsequently if peer mentored patients had better health outcomes. The sample consists of 1639 patients who were entered into the Thomas Street Patient Mentor Database between May 2005 and June 2007. The assignment to the mentored group was haphazardly conducted based on mentor availability. The data from the Mentor Database was then analyzed using descriptive statistical software (SPSS version 15; SPSS Inc., Chicago, Illinois, USA). Results indicated that patients who had a mentor at intake were more likely to return for primary care HIV visits at 90 and 180 days. Mentored patients also were more likely to be prescribed ART within 180 days from intake. Other risk factors that impacted remaining in care included gender, previous care status, time from diagnosis to intake visit, and intravenous drug use. Clinical health outcomes did not differ significantly between groups. This supports that mentoring did improve outcomes. Continuing to use peer-mentoring programs for HIV care may help in increasing retention of patients in care and improving patients' health in a cost effective manner. Future research on the effects of peer mentoring on mentors, and effects of concordance of mentor and patient demographics may help to further improve peer-mentoring programs. ^

The association of peer victimization and/or bullying perpetration and body dissatisfaction in elementary students from the healthy passages baseline study

This is the first U.S. study to investigate the association between peer victimization and/or bullying perpetration and body image dissatisfaction in American elementary school students. The study used data collected from the Healthy Passages baseline cohort of 5152 ethnically diverse fifth grade students from Alabama, Texas, and California. The overall prevalence of body dissatisfaction in our fifth grade sample was 50%. Students who were dissatisfied with their bodies were 23% more likely to be involved in peer victimization than students who were satisfied with their bodies (OR = 1.23; 95% CI = 1.02, 1.48). No significant associations were found between bullying status or bully-victim status and body dissatisfaction. Other factors that contributed significantly to a student's body image status were BMI, level of self-worth, level of household income, gender, pubertal timing and support received from adults (other than parents). It is noteworthy that those who were dissatisfied were heavier, came from lower income homes and were more likely to be male. Additional longitudinal studies are needed to confirm these associations, especially among large ethnically and socio-economically diverse samples. ^

Young Jewish adults sexual behaviors Peer, parental and surrounding influences

A qualitative study was conducted on young Jewish adults to determine cultural sexual health patterns with in the Jewish adolescent community. The young Jewish adults were recruited through Jewish social settings, such as Hillel Student Centers in Austin and Houston, Texas. Jewish was self-defined. A young adult, for this study, was defined as being between the ages of 18 and 23. Both female and males are needed in the study group. Individual interviews revealed 35 themes identifying the cultural, parental, peer, and surrounding factors that affect sexual behaviors during Jewish adolescence. Overall, this research demonstrates the need to further study and understand the culture and behaviors with in the Jewish community to then create a tailored intervention on healthy sexuality.^

Beyond Bullying: Transforming the Culture of Peer Abuse

Bullying needs to be understood and positioned as a form of child abuse – peer abuse. For too many people, bullying is a benign term. This article will include information collected from a wide-range of researchers and discussions with over 50,000 students that I have facilitated during the past twenty years. The content will focus on new morbidities related to bullying such as depression and suicide, obesity, eating disorders, food allergies, juvenile diabetes, truancy, and substance and alcohol abuse. Making a cultural change in our society will require identified Change Agents, along with recommendations for collaboration, policies, projects and legislation.

Student Reciprocal Peer Teaching as a Method for Active Learning: An Experience in an Electrotechnical Laboratory

Active learning is one of the most efficient mechanisms for learning, according to the psychology of learning. When students act as teachers for other students, the communication is more fluent and knowledge is transferred easier than in a traditional classroom. This teaching method is referred to in the literature as reciprocal peer teaching. In this study, the method is applied to laboratory sessions of a higher education institution course, and the students who act as teachers are referred to as ‘‘laboratory monitors.’’ A particular way to select the monitors and its impact in the final marks is proposed. A total of 181 students participated in the experiment, experiences with laboratory monitors are discussed, and methods for motivating and training laboratory monitors and regular students are proposed. The types of laboratory sessions that can be led by classmates are discussed. This work is related to the changes in teaching methods in the Spanish higher education system, prompted by the Bologna Process for the construction of the European Higher Education Area

P2P assisted streaming for low popularity VoD contents

The Video on Demand (VoD) service is becoming a dominant service in the telecommunication market due to the great convenience regarding the choice of content items and their independent viewing time. However, due to its high traffic demand nature, the VoD streaming systems are faced with the problem of huge amounts of traffic generated in the core of the network, especially for serving the requests for content items that are not in the top popularity range. Therefore, we propose a peer assisted VoD model that takes advantage of the clients unused uplink and storage capacity to serve requests for less popular items with the objective to keep the traffic on the periphery of the network, reduce the transport cost in the core of the network and make the system more scalable.
