Objective. In September 2005, approximately 150,000 Gulf Coast residents fled to Houston, Texas, seeking shelter following Hurricane Katrina. Since the majority of evacuees were poor African Americans, the political and social consequences of the storm inspired a national dialogue on race and class. However, in Houston, the discourse on Katrina evacuees also involved immigration concerns. The city's distinction as a gateway to new arrivals influenced the dialogue on the evacuees' impact on the local area. This article assesses the extent to which race, class, and immigration concerns influenced Houstonians' beliefs about the Katrina evacuees. Methods. We analyze data from the 2006 and 2008 Houston Area Survey in order to assess attitudes toward these newcomers at two distinct time periods: within six months of their arrival and then again more than two years later. Results. Our findings show that both national and local factors influenced beliefs about the Katrina evacuees. Conclusions. The dynamics of race/ethnicity and apprehension toward immigrants drove largely antagonistic beliefs about the mostly poor, mostly black new arrivals.  相似文献

Due to a revision of the land utilisation plan the town Lichtenberg had initiated a civic participation. After four official workshops the citizens decided to continue on their own. The article describes a best practice example of a citizen’s action committee. The citizens develop concepts and work pro bono for their community. Their aim is to prepare the town for future challenges. The citizen’s action committee works closely together with the town’s council. In the meantime there are three projects that have been finished successfully. One project–the development of a shared vision–is described more detailed. The author summarizes experiences that could be beneficial for other citizen’s action committees.  相似文献

Interactions with mothers and fathers form a critical foundation for youths’ later peer relationships. This study focused on the associations of maternal and paternal sensitivity in third grade with friendship outcomes in sixth grade. Because interactions with parents provide the earliest opportunities for children to learn prosocial behaviors such as cooperation, and cooperation is theoretically conceptualized as a foundation of friendship, cooperation may play a role in the link between parenting and children’s later social relationships. Using the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development sample (N = 955; 51% female; 83% White), and a multimethod, multireporter longitudinal design, children’s cooperation was tested as a mediating mechanism that linked parental sensitivity to early adolescent friendship. Results indicated that most indirect paths from both mothers and fathers’ sensitivity to observed friendship interactions and perceived friendship quality, via cooperation, were significant. Findings provide a more concrete understanding of how parental sensitivity translates to better friendships.  相似文献

General career research suggests that many factors may influence how people select a career, including information about or exposure to the career. The focus of this paper is upon how exposure to a social worker personally (e.g. friend or family) or in a therapeutic capacity (e.g. received social work therapy) may influence the decision to become a social worker, when compared to other disciplines. The results showed that 63% of 64 social work students had personal and/or professional exposure to social work prior to making a career decision. When compared to other students (n?=?447) the social work students were significantly more likely to have accessed social work services (themselves or a family member). The influence of a friend who was a social worker and working with a social worker was noteworthy for mature-aged students. These results highlight that every interaction social workers have with the community provides valuable information about the profession and gives insight into social work as a career. Additionally, the results suggest that the increase in numbers of social workers and the influence of that exposure to a social worker have resulted in an increase in the use of social work services by students, and may continue to rise in the future.  相似文献

Risk analysis standards are often employed to protect critical infrastructures, which are vital to a nation's security, economy, and safety of its citizens. We present an analysis framework for evaluating such standards and apply it to the J100-10 risk analysis standard for water and wastewater systems. In doing so, we identify gaps between practices recommended in the standard and the state of the art. While individual processes found within infrastructure risk analysis standards have been evaluated in the past, we present a foundational review and focus specifically on water systems. By highlighting both the conceptual shortcomings and practical limitations, we aim to prioritize the shortcomings needed to be addressed. Key findings from this study include (1) risk definitions fail to address notions of uncertainty, (2) the sole use of “worst reasonable case” assumptions can lead to mischaracterizations of risk, (3) analysis of risk and resilience at the threat-asset resolution ignores dependencies within the system, and (4) stakeholder values need to be assessed when balancing the tradeoffs between risk reduction and resilience enhancement.  相似文献

Background and aimSymptoms of perinatal depression and anxiety are usually described and understood from a nosological perspective. This research sought to gain insight into women's lived experience of postnatal depression and anxiety, the factors that contribute to these symptoms and the context in which they develop.MethodFace to face and telephone interviews were conducted with 28 women from metropolitan and rural areas across Australia, who had experienced postnatal depression and/or anxiety within the last five years. Analysis was conducted from a grounded theory perspective.FindingsParticular symptoms of anxiety and depression develop in the context of the numerous changes inherent to the transition to motherhood and contribute to a common experience of frustration and loss. Symptoms were also associated with feelings of dissatisfaction with the pregnancy and motherhood experience.ConclusionsThe findings provide useful insights into women's experiences of mental health symptoms during the perinatal period, how these symptoms present and the factors involved in their development and maintenance. The need to consider women's perspectives to develop resources and health promotions strategies, as well as within the context of relationships with health professionals is highlighted. The study emphasizes the need for greater, more accurate information surrounding perinatal depression and the need to increase the profile and awareness of anxiety disorders.  相似文献

Previous studies have suggested that Asian parents’ high academic expectations can lead to negative mental health outcomes among Asian American youth. We explore this hypothesis by analyzing data collected in an affluent, suburban high school with a large Asian American population. We examine the relationships between parent expectations, students’ relationships with their parents, and mental health outcomes among Asian American (predominantly Indian American and Chinese American) and white youth. We find that the quality of parent-child relationships is associated with mental health outcomes and that the association between parent expectations and mental health outcomes is insignificant after controlling for these relationships. We discuss significant differences by race and gender. The findings presented expand our understanding of the influence of Asian parents. They suggest that focusing on improving parent-child relationships, as opposed to altering parents’ expectations, might lead to improved mental health outcomes for Asian American youth, particularly for those in affluent communities.  相似文献

In this article, we model functional magnetic resonance imaging (fMRI) data for event-related experiment data using a fourth degree spline to fit voxel specific blood oxygenation level-dependent (BOLD) responses. The data are preprocessed for removing long term temporal components such as drifts using wavelet approximations. The spatial dependence is incorporated in the data by the application of 3D Gaussian spatial filter. The methodology assigns an activation score to each trial based on the voxel specific characteristics of the response curve. The proposed procedure has a capability of being fully automated and it produces activation images based on overall scores assigned to each voxel. The methodology is illustrated on real data from an event-related design experiment of visually guided saccades (VGS).  相似文献

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.  相似文献
