Impacts of urbanization on biodiversity are commonly studied using urbanization gradients which provide a space-for-time substitution in estimating consequences of urban expansion. Rates of urbanization and human population growth are high in tropical countries of the developing world, which also hold most of the world’s biodiversity hot-spots, yet few studies have considered biodiversity trends along urban gradients in these regions. Bird communities across a gradient of nine sites in Uganda, from the city centre of Kampala to outlying rural locations, were studied over a six year period. These sites were ordered along an urbanization gradient using Principle Components Analysis based on habitat variables estimated at each site. Bird species richness showed a decrease from rural to urban sites, a trend especially evident in forest birds. There was no clear pattern in total abundance, total biomass or biomass per individual along the gradient. However, this latter result was heavily influenced by a colony of Marabou Storks at one site. When this species was omitted, there was evidence of a positive trend with urbanization, showing that as species richness decreased, the bird community was increasingly dominated by larger species with increasing urbanization, which were mainly scavengers able to exploit human refuse. These results provide further support for the negative impacts of urbanization on species richness, but also demonstrate trends in abundance and biomass are variable across different regions. In particular, the increasing dominance of larger species in urban areas may be relevant to certain geographic and/or socioeconomic contexts. 相似文献

In this article, I engage with Edward Said's Orientalism and various perspectives within the othering paradigm to analyze the emergence and transformation of radicalization discourses in the news media. Employing discourse analysis of 607 New York Times articles from 1969 to 2014, this article demonstrates that radicalization discourses are not new but are the result of complex sociolinguistic and historical developments that cannot be reduced to dominant contemporary understandings of the concept or to singular events or crises. The news articles were then compared to 850 government documents, speeches, and other official communications. The analysis of the data indicates that media conceptualizations of radicalization, which once denoted political and economic differences, have now shifted to overwhelmingly focus on Islam. As such, radicalization discourse now evokes the construct radicalization as symbolic marker of conflict between the West and the East. I also advanced the established notion that the news media employ strategic discursive strategies that contribute to conceptual distinctions that are used to construct Muslims as an “alien other” to the West. 相似文献

Although research has demonstrated the manifestation of racial bias by measuring overt attitudes and behaviors, there has been little examination of the subtle nonverbal cues that may also characterize such bias. The present study investigates implicit racial bias by analyzing nonverbal behaviors of individuals shown video of a criminal suspect whose ethnic identity is manipulated to be Black or White. Participants appeared significantly more uncertain about what they were saying when describing the White suspect than when describing the Black suspect. Participants were also more likely to display “open” posture when describing the Black suspect but “closed” posture (e.g., crossed arms) when describing the White suspect. The results indicate that biases in attitudes and beliefs might be reliably detected and measured through body language. The findings are discussed in terms of how nonverbal behaviors may reveal more subtle forms of prejudice and miscommunication. Contextual correlations between specific nonverbal behaviors and affective states are also discussed. 相似文献

Two overseas survey-based scales measuring perceived quality of neighbourhood were adapted and replicated in a New Zealand
context. An Italian study (Bonaiuto, Fornara, and Bonnes. (2003). Landscape and Urban Planning, 65, 41–52) measuring Perceived Residential Environmental Quality (PREQ) and an American study (Carp and Carp. (1982). Journal of Environmental Psychology, 2, 295–312) using the Perceived Environmental Quality Indices (PEQI) were applied to a sample of Auckland residents, separated
into low, medium, and high population density areas. The surveys measured attitudes towards subjects such as noise, neighbours,
accessibility, green areas, welfare services, recreational services, safety, maintenance, environmental health, transport
services, and characteristics of an ideal neighbourhood, and were completed by 369 respondents. Primary analyses examined
differences in perception across the three density groups. The factor structures of both scales were replicated with the Auckland
sample, and differences across densities were found for subscales of the PREQ. The results are discussed in relation to the
cross-cultural similarities of perceived environmental quality, and the concept that environmental satisfaction is based on
balancing aspects of the residential environment is proposed.

Arrivals of new immigrants into the south Florida area have put increased pressure on housing markets and fostered renewed efforts to provide more affordable housing. Many view household extension largely as a response to the lack of a sufficient amount of affordable housing. This paper examines the nature, proportion and housing condition of nuclear and extended households in the Miami-Fort Lauderdale area. The study also investigates how the incidence and housing situation of extended households has changed during the period from 1986 to 1990. This study illustrates that extended families in the Miami-Fort Lauderdale area are not uniformly worse off than nuclear families, given ethnicity and income level. While the area's housing problems require attention, some of that attention should be focused on removing institutional barriers to household extension and to providing broader housing choices for minority ethnic groups. 相似文献

In their professional capacities doctors are often confronted with clients who present with psycho-sexual problems. At the present time Australian medical students are provided with very little instruction in the areas of human sexual behaviour. This paper examines the attitudes and amount of information possessed by a cohort of second year medical students compared with groups of first and fifth year students; these attitudes and levels of information are then related to students' sex, religious affiliation, strength of religious conviction, where this is seen to be relevant. It is shown that some areas of ignorance exist. The paper concludes by outlining some aspects relevant to courses in human sexual behaviour. 相似文献

Clinical and literary citations to a syndrome in which a sexual relationship is established with a human representation (usually a statue) are examined. Notwithstanding the observations of Havelock Ellis, Krafft‐Ebing, and more modern commentators, the present survey found only a single documented instance where this condition existed as part of a complex manifestation of symptoms but a number of instances where it occurred as a pornographic fantasy. 相似文献
