Clean and green organizing in urban neighborhoods: Measuring perceived and objective outcomes

ABSTRACT

One way in which urban community organizations attempt to improve neighborhood health is through cleaning and greening efforts. Few studies have evaluated how such efforts are related to changes in both residents’ perceptions of neighborhoods and objective community-wide cleaning and greening indicators over time. Drawing upon quantitative and qualitative data collected during an evaluation of a community-building initiative in two communities, results show how neighborhood changes in cleaning and greening were reflected in perceived and objective measures and how these measures compare across different time periods and sub-groups of residents within the two target communities. We provide suggestions for additional ways that future evaluations of urban cleaning and greening efforts can examine the impact.     

Teaching Communication in a Statistical Collaboration Course: A Feasible,Project-Based,Multimodal Curriculum

Many schools offer a statistical collaboration curriculum using standard instructional methods such as lectures whereby students are taught to successfully apply their training. The process of building statisticians' collaborative skills and characteristics can be challenging due to logistical issues, time constraints, unstructured research problems, and resources. Instructors vary in their pedagogy and topics taught, and students' experiences vary. There is a dearth of literature describing how to implement a course integrating communication skills, critical thinking, collaboration, and the integration of team members in a learner-centered format. Few courses integrate behavior-based learning using role-playing, video demonstration and feedback, case-based teaching activities, and presentation of basic statistical concepts. We have developed and implemented a two-semester biostatistics collaboration course, of which the purpose is to develop the students' knowledge, skills, attitudes, and behaviors necessary to interact effectively with investigators. Our innovative curriculum uses a multimodal, project-based, experiential process to address real-world problems provided by real and/or simulated collaborators while minimizing usual challenges. Rubrics and peer evaluation forms are offered as online supplementary materials. This article describes how a collaboration curriculum focusing on communication and team practice is feasible, how it enhances skill and professionalism, and how it can be implemented at other institutions.     

Abstinence-Based Versus Service Learning Prevention Education in Small Groups: Effects on the Life Plans of Young Adolescents

The purpose of this study was to assess the impact of two types of pregnancy prevention programs on youths’ behavioral intentions. Before and after participating in a series of adolescent pregnancy prevention support group meetings guided by abstinence OR service learning curricula, 88 youth, ages 13 and 14 years, forecasted their future life plans. Repeated measures analysis with two groups by two time points was conducted to assess changes in life forecasts over time and differences between the programs. From pre-test to post-test in the abstinence-based program there was reduction in plans to have first baby before marriage (p < .05). There were no significant changes in youths’ forecasts regarding sexual debut in either group. Implications for research and practice are discussed.     

Interpersonal Influences on Students' Academic and Career Decisions: The Impact of Sexual Orientation

The authors investigated differences in interpersonal influences on career decision making between gay, lesbian, and bisexual (GLB) and heterosexual college students. Contrary to hypotheses, GLB students reported having more career role models than did heterosexual students, and the amount of inspiration received from role models did not differ between the 2 groups. However, GLB students perceived they received less support and guidance from others in their academic and career decision making. As expected, GLB students were more likely to endorse the importance of a career role model's sexual orientation and support of people with their own sexual orientation. Career intervention and research implications are discussed.     

Impact of rater personality on transformational and transactional leadership ratings

This study addresses the role of rater personality in ratings of transformational and transactional leadership. In a naturalistic field study, we found that rater personality (i.e., agreeableness, openness, extraversion, and conscientiousness) was positively associated with ratings of transformational leadership, but significant rater personality effects were not found in an experimental study where leadership behavior was invariant. These results suggest that disagreements among raters about leaders' behaviors are not due solely to random error and may instead reflect true differences either in (a) the behaviors leaders exhibit toward individual followers or (b) personality-related differences between followers in attention to and recall of leadership behaviors. We also found that personality (of subordinates and peers) was not randomly distributed across leaders, though clustering effects were generally small. Practically, our results suggest that (a) individual reports of leadership may be better at predicting leadership outcomes than aggregated group reports – especially those related to individual attitudes and behaviors – though they are rarely used in the literature; (b) aggregation is complicated because rater personality is associated with leadership ratings and is not randomly distributed across leaders; and (c) corrections for measurement error based on inter-rater agreement may not be appropriate due to non-random unique rater variance.     

Mixture Multi-state Markov Regression Model

Although heterogeneity across individuals may be reduced when a two-state process is extended into a multi-state process, the discrepancy between the observed and the predicted for some states may still exist owing to two possibilities, unobserved mixture distribution in the initial state and the effect of measured covariates on subsequent multi-state disease progression. In the present study, we developed a mixture Markov exponential regression model to take account of the above-mentioned heterogeneity across individuals (subject-to-subject variability) with a systematic model selection based on the likelihood ratio test. The model was successfully demonstrated by an empirical example on surveillance of patients with small hepatocellular carcinoma treated by non-surgical methods. The estimated results suggested that the model with the incorporation of unobserved mixture distribution behaves better than the one without. Complete and partial effects regarding risk factors on different subsequent multi-state transitions were identified using a homogeneous Markov model. The combination of both initial mixture distribution and homogeneous Markov exponential regression model makes a significant contribution to reducing heterogeneity across individuals and over time for disease progression.     

Home(land) Décor: China Adoptive Parents’ Consumption of Chinese Cultural Objects for Display in their Homes

American parents of children adopted from China frequently consume Chinese cultural objects for display in their homes. While parents defend this consumption for display as an effort to validate their children’s ethno-cultural origins, they also reveal how it signifies and solidifies their own identifications with Chinese culture. As part of a larger research project examining China adoptive parents’ evolving “Chinese” identities, this paper asks: Which parents “become ‘Chinese’” through the consumption and display of Chinese cultural objects, and why? To answer this question, I conducted semi-structured in-depth interviews with 91 Americans in the China adoption process and ethnographic fieldwork at two different field-sites: Families with Children from China (FCC) Chinese cultural celebrations and Chinese culture camps organized by/for China adoptive families. Focusing on the emergent and personal meanings that parents give to Chinese cultural objects, I demonstrate how these meanings both structure parents’ consumption and yield a display differential. In doing so, I reveal that white European-American parents and mothers are most likely to engage in this consumption and display, thereby amending the three types of ethno-cultural identity consumption represented in the literature. Specifically, I expose the central role of race in ethno-cultural identity consumption; demonstrate that the collective category of reference for ethno-cultural identity consumption is not always an ethnic category (in this case, such consumption refers to a gendered category); and illustrate the ways in which global ethno-cultural identity consumption both appeals to and satisfies distinctly local constructs.
