The influence of land use type and municipal context on urban tree species diversity

Recent research has focused on the ways urban forest patterns vary in relation to level of urbanization and socioeconomic characteristics, with most studies limited to one urban land use type or multiple non-differentiate land uses. Additionally, the majority of studies examining urban forest patterns focus on canopy cover extent, with less attention given to patterns of species diversity. This study explores how tree species diversity varies across different urban land uses and municipal boundaries to better understand the role of land use types in shaping urban forest patterns. The goal is addressed through an exploration of plot-level tree data in the urban municipalities of Peel Region located in the Greater Toronto Area (Ontario, Canada). Species composition and standard diversity metrics are calculated for eight land use types and four municipalities. Our results show that differences in diversity metrics and species composition are greater between urban land uses than municipalities. Moreover, Peel’s urban forest has relatively high alpha diversity but many species are present on only one land use type. The results suggest that different causal processes are associated with each land use type, and that urban forest managers should adopt land use-specific strategies to meet species composition goals within the urban forest.     

The Characteristics of Two Samples of Women Seeking Abortion in Queensland

The legalization of abortion is still a live issue in Queensland. The numbers and characteristics of women seeking abortion through the Children by Choice Association in 1973–74 and in 1980 were studied since no official statistics on abortion are available. From 1974 to 1980 there was a threefold growth in demand and a threefold rise in the proportion seeking their second or subsequent abortion. Both samples closely reflect the Queensland population as measured by place of birth and religious affiliation. Contraceptive knowledge was found to be associated with education while the proportion who stated they had formal lessons at school rose from 3% to 16% between the samples. In both samples two-thirds of the pregnancies resulted when no physical contraceptive was in use. Social characteristics of the women and men involved were investigated, as well as factors in the abortion decision.     

Community Size,Individual Social Position,and Community Attachment1

Abstract The objective of this investigation is to elaborate and test the linear development and systemic models of community attachment. We focus on the interplay of community size, five social position variables, and three dimensions of community attachment, namely, involvement, amity, and sentiment. Data are obtained from a statewide migration telephone survey of 851 respondents aged 18 and over, conducted in Utah in October 1988. We focus on a weighted subsample of 415 nonmetropolitan respondents. Multiple Classification Analysis (MCA) techniques are employed. Contrary to the linear development model, community size did not have an independent inverse impact on community involvement, amity, and sentiment. Results do vary by social position and community attachment dimensions.     

A Survey of 100 Community Colleges on Student Substance Use,Programming, and Collaborations

Abstract

Objective: The objective was to survey community college personnel about student substance use, and infrastructure (staff and funding), programs, and collaborations dedicated to substance use prevention. Participants: The sample included 100 administrators, faculty, and health services staff at 100 community colleges. Methods: Participants completed a Web-based survey. Results: Participants reported a number of alcohol and other drug (AOD) related concerns. Despite limited staff and funding dedicated to AOD, institutions are implementing a number of programs, although many are not implementing some of the programs popular at traditional 4-year colleges. They are also collaborating with a number of on- and off-campus groups. The availability of staff and funding dedicated to AOD, and the presence of residence halls, is associated with health programming and substance abuse collaborations. Conclusions: Results suggest that there is a need for increased research to understand the most effective AOD prevention strategies for community colleges.     

Contemporary Political Communications: Audiences, Politicians and the Media in International Research

Research into political communication has grown rapidly in the past three decades, shifting from specific, quantitative and utilitarian studies to include a broad variety of research questions, methods and theoretical frameworks. Interdisciplinary work in political communication takes audiences, political actors (such as governments and politicians), and media content and media institutions as central foci. Research has traditionally focused on election campaign-specific studies within national contexts. Emerging research, however, is now addressing broader questions about media texts and organisations and also about representations and power. This research is working to trace technological changes and developments in an era of globalised media and political communication and developing new, complex conceptions of audience agency and reception.     

Healthcare Providers’ Nonverbal Behavior can Lead Patients to Show Their Pain More Accurately: An Analogue Study

Accurate pain assessment is a joint function of both the judge perceiving correct (valid) cues of pain and targets displaying valid indicators of pain. The present research examined whether the judgeability of pain expressions could be altered by manipulating the nonverbal supportiveness of a videotaped physician who guided targets through an experimentally induced pain experience in the laboratory. Ten-s video clips of these targets during their pain experience were viewed by 95 naïve judges who assessed each target’s pain on an 11-point numeric rating scale. In addition, the video clips were rated by independent coders on 9-point scales (focused, calm, tense, distressed, composed, fidgety, determined, bored, and nervous). Judges’ pain assessment accuracy was calculated by correlating their inferred pain rating for each target with targets’ self-reported pain. Pain targets assigned to interact with the nonverbally supportive physician displayed more valid impressions of their pain and judges had higher pain assessment accuracy when viewing these targets compared to targets assigned to interact with the nonverbally unsupportive physician. Interventions for caregivers and healthcare providers that emphasize the importance of nonverbal behavior when interacting with pain sufferers are discussed.     

Masculinity and Sexual Violence: Assessing the State of the Field

Despite strong evidence that men perpetrate most acts of sexual violence, little is known about the factors that lead some men to commit such harmful acts. A growing body of feminist scholarship has begun to explore this question, although the disciplinary and geographic breadth of these studies has prevented the development of a cohesive research agenda. This literature review contributes to this task by reviewing the major theoretical contributions to the study of masculinity and sexual violence, detailing some of the ways in which sexual violence aids in the production of masculine individuals, groups, and states. Taken as a whole, we argue that this body of scholarship views sexual violence as a mechanism through which social constructions of masculinity are produced and reproduced, although the forms that this violence takes vary by context. We conclude with a discussion of some of the theoretical and empirical limitations of this research and consider the implications of these findings for public policy.     

How rival partners compete based on cooperation?

Prior studies of coopetition have explained the what, how and why of firms cooperating with competitors. Among these, examining the how question as to the stream of coopetition dynamics is the most challenging theme. Previous research has focused much more on the cooperation side. Less attention has been paid to the competition side to reveal what happens to competition after the competitors have collaborated. This study sheds light on the issue of cooperation-based competition by answering the question: while cooperating with competitors, how do rival partners compete based on cooperation? Linking the competitive dynamics perspective to coopetition, we conducted a single-case study to analyse the competition between two leading competitors in the Taiwanese bicycle industry. We collected the reported issues pertaining to the competition in the European market and supported by in-depth interviews. The analysis leads us to develop three propositions and a conceptual framework for illustrating the cooperation-based competition and addressing how cooperation may influence competition in a coopetition relationship. This study provides new insights into a theoretical issue of cooperation-based competition. The case also provides management implications while taking a coopetition strategy.     

Community size preference status,community satisfaction and migration intentions

Increasing attention has been directed to the effect of cognitive factors on migration decision making. We evaluate the influence of community size preference status and six domains of community satisfaction on migration intentions per se and short- vs. longterm migration intentions, separately, simultaneously, and with controls on community involvement and social position. The data are from a 1988 statewide migration survey of 851 Utahns. Separate multivariate analyses are conducted for metropolitan and nonmetropolitan residents. Satisfaction/dissatisfaction with selected features of community life primarily impacts migration intentions per se while community size preference status dominates the time frame of migration intentions.
