Pressures of rapid development continue to increase, and recreational activities are becoming a prominent driving force in many urban wildlife communities. Freshwater turtles live in many urban environments, yet little attention has been given to the impact of human recreation upon these communities. We examined the response of basking turtles to observer presence along the towpath of a recreational canal in central New Jersey. All species, except for turtles of the family Kinosternidae, were more frequently observed basking on substrate with less than 50 % canopy cover, log substrate was most preferred, and turtles on the towpath side basked an average of 3 m from the towpath. Turtles were vigilant and over 75 % of C. picta, T.S. elegans, and P. rubriventris responded to observer presence by retreating (swimming away). The distance from the towpath turtles were first seen basking by the observer (approach distance) was significantly correlated with the flight-initiation distance (distance of first respond to observer). Nearly 80 % of the variability in flight initiation distance for Kinosternidae was accounted for by the percent canopy cover, percent cloud cover, and height basking above the water. Researchers aiming to quantify and manage human recreational impact on turtles should examine flight-initiation distances. We encourage wildlife managers of urban parks to construct towpaths or recreational areas at a minimum of 7 m from the water’s edge, maintain moderate vegetation in basking areas, and construct additional basking platforms opposite from towpaths or at great distances from human recreational areas. 相似文献

Charitable nonprofit organizations have long been under scrutiny with regard to how they manage excess funds, particularly cash holdings. Given previous empirical evidence, agency problems have been treated as an effective lens to explain the consequences of cash holdings among nonprofits. That is, nonprofit managers spend cash holdings for their own interests as opposed to the social interests of the organization. This study revisits the question of how charities manage extra cash and further examines the role of government funding in nonprofits' spending decisions. The results suggest that nonprofit managers make decisions on how to manage extra cash in accordance with the level of cash holdings; therefore, agency problems do not effectively explain how nonprofits manage extra cash. Furthermore, the results illustrate two contrasting roles of government funding in nonprofits' financial behavior: government funding may be used to monitor unscrupulous behaviors among managers, but it may also restrain nonprofits from investing in human capital. 相似文献

We report data concerning cross-cultural judgments of emotion in spontaneously produced facial expressions. Americans, Japanese,
British, and International Students in the US reliably attributed emotions to the expressions of Olympic judo athletes at
the end of a match for a medal, and at two times during the subsequent medal ceremonies. There were some observer culture
differences in absolute attribution agreement rates, but high cross-cultural agreement in differences in attribution rates
across expressions (relative agreement rates). Moreover, we operationalized signal clarity and demonstrated that it was associated
with agreement rates similarly in all cultures. Finally, we obtained judgments of won-lost match outcomes and medal finish,
and demonstrated that the emotion judgments were associated with accuracy in judgments of outcomes. These findings demonstrated
that members of different cultures reliably judge spontaneously expressed emotions, and that across observer cultures, lower
absolute agreement rates are related to noise produced by non-emotional facial behaviors. Also, the findings suggested that
observers of different cultures utilize the same facial cues when judging emotions, and that the signal value of facial expressions
is similar across cultures. 相似文献

Adding to the growing body of literature on outcomes for children living in orphanages and children's homes, this qualitative study explored the perceptions of institutional personnel – caregivers, staff members, supervisors, and administrators – about organizational factors affecting their ability to care for orphaned and vulnerable children living in institutions in the Ashanti Region of Ghana. The participants in this study consisted of 59 caregivers, 7 supervisors, 10 administrators, 4 cooks, 4 teachers, 1 social worker, 1 security guard/driver, and 6 women classified as house helpers. Individual interviews were conducted using an English-written and stated semistructured interview guide the researchers had created. The data from the 92 interviews were transcribed and coded using inductive methodologies. The results revealed concerns from the personnel about their institutions' lack of adequate funding for essential items, including food and medicine for the children. The personnel were also concerned about the lack of appropriate workplace standards to ensure the sustainability of a viable workplace environment, including inadequate training, supervision, communication procedures, and staffing patterns, and collaborative partnerships and associations with other public or private community-based institutions. The findings from this study have considerable policy, practice, and research implications for social workers. 相似文献

Data collected out of the breeding season suggest that House sparrows (Passer domesticus) from the urban populations are characterized by a smaller body size and poorer body condition compared to birds from rural populations. Considering an urbanized Eurasian Sparrowhawk (Accipiter nisus) and other potential predators, a new predator-prey dependency is developing that can also be a reason for the House sparrow’s poorer condition. This study was aimed at comparing the multivariate biometrical characteristics and few body condition indices of adult birds from urban and rural populations during the breeding season. It was hypothesized that a higher predation risk during the breeding season concerns mainly males, thus affecting their poorer condition. Most of the condition indices of males were significantly lower in the urban population. Males from the urban populations had lower body mass, shorter tarsus, longer alula, greater Kipp’s distance and higher wing pointedness index in comparison to the birds from rural populations, whereas these differences were not found between females. We suggest that the lower body condition and biometric differences in the analyzed birds are a means of adapting to the new predator-prey scheme in accordance to the tradeoff theory between starvation and predation risks. A lower condition of birds in poor foraging urban habitats and higher predation risk may be indicative of a declining population. 相似文献

ABSTRACT Activist groups in ethnographic research re-negotiated our Ethics Committee’s expected order of securing consent before data collection, demonstrating the importance of researchers taking time to build relationships first. Although the Ethics Committee expected us to obtain group consent, the literature provides little guidance on how to do this. We developed a Memorandum of Understanding to summarize what forms of participant observation each group agreed to and how we would reciprocate. In this article, we (re)conceptualize consent, using analogies to consent in social contract theory and sexual relations to offer a critical perspective on what constitutes consent. We argue that taking time to build relationships before expecting research participants to consent and replacing informed consent with a negotiated agreement is a more ethical approach. We advocate for Ethics Committees to expand the meaning of ‘informed consent’ and review its timing, especially for ethnographic research with groups. 相似文献

We explored adolescents’ (12‐ to 18‐year‐olds; n = 51) awareness of their audience and subsequent self‐presentation practices on Facebook and Instagram through focus group discussions. Findings suggest that teens, who are developmentally able to perceive a situation from the third‐person perspective and who value peer approval, purposefully share content to appear interesting, well liked, and attractive. Some teens invested great effort into posting by these norms, even asking their friends to help; however, this was more common among girls. Older teens especially discussed taking the perspective of their audience when deciding what to post, which is consistent with the finding that perspective taking continues to develop throughout adolescence. These findings suggest that perspective taking skills and need for peer approval influence self‐presentation online. 相似文献

In research and policy discourse, conceptualizations of fertility decision-making often assume that people only consider circumstances within national borders. In an integrated Europe, citizens may know about and compare conditions across countries. Such comparisons may influence the way people think about and respond to childrearing costs. To explore this possibility and its implications, we present evidence from 44 in-depth interviews with Polish parents in the United Kingdom and Poland. Explanations of childbearing decisions involved comparisons of policy packages and living standards across countries. Individuals in Poland used richer European countries as an important reference point, rather than recent conditions in Poland. In contrast, migrants often positively assessed their relatively disadvantaged circumstances by using the Polish setting as a reference. The findings could help explain why, despite substantial policy efforts, fertility has remained at very low levels in poorer European countries, while migrants from those countries often have higher fertility abroad. 相似文献
