Muslim communities have frequently been the victim of vilification and discrimination in Australia and the broader Asian region. This article discusses and compares the narratives around Muslim vilification in Australia and Sri Lanka. Despite the fact that these two nations are vastly different in size, demographics and cultural history, I will argue that there are remarkable similarities in how Muslims are subject to attack in both nations. The hate speech occasioned against Muslims in Sri Lanka and Australia is shaped by almost identical narrative structures and is cultivated in similar online environments. In both cases, anti‐Muslim animus is fuelled by a fear of displacement and perceived contamination of what nativists regard as ethnically sovereign territory. I will argue that the underlying sub‐text in both cases is owed to a repulsion to the physical presence of Muslims which can be understood in terms of Mary Douglas' concept of the moral pollutant.  相似文献

To improve understanding of human impacts on headwater stream condition, we quantified relationships between human, terrestrial landscape, and stream system variables in 29 central Iowa watersheds. Across study watersheds, between 0 and 100 % of total land area was characterized as “urban” (developed and barren land), whereas cultivated land constituted between 0 and 71 % of watershed area. Several variables were measured for each stream and associated watershed. Strengths of correlative relationships were used to select variables for path analysis, which we used to gain insight into factors affecting stream condition by evaluating direct and indirect effects of human system variables, terrestrial landscape variables, and physical stream variables on stream invertebrates. Results indicated that in predominantly urban watersheds, contaminant inputs to streams (measured by streamwater conductivity) negatively affected invertebrates, including EPT taxa (Ephemeroptera, Plecoptera, Trichoptera), and streamwater contaminant concentrations increased with impervious surface and human population density in the watershed. In rural watersheds, high streamwater nitrogen concentrations associated with cultivated land were related to declines in invertebrate taxon richness. Independent of land use, invertebrate abundance and taxonomic diversity were positively related to coarse substrate abundance on the streambed. Additionally, stream flow (discharge) increased with watershed area, which in turn increased invertebrate taxonomic diversity. Apparently, mechanisms responsible for human impacts on stream condition in central Iowa depend on dominant land use in the watershed. Additionally, stream ecosystems with high quality benthic habitat, and those located in large watersheds with greater flow, appear to be more resilient to land use effects.  相似文献

This study aimed to explore, articulate and expand on existing concepts of recovery and paid peer support within consumer-operated mental health organizations. Focus groups and interviews were conducted with 32 participants to identify elements of paid peer support work in two organizations in Queensland, Australia. Participants included peer-supported consumers, paid peer support workers, managers and other key stakeholders. Through a grounded theory analysis, eight categories of paid peer support were identified. For the most part, the categories aligned well with evidence in the literature. However, two of these categories, issues of power and the ‘dark side’ of peer support, have been relatively unexplored and understated in previous studies. These findings provide an expanded understanding of the role of paid peer support as part of the recovery process in mental health service delivery. The effective use of paid peer support workers can be enhanced through attention to the issues identified.  相似文献

U.S. immigration has changed dramatically in the last 20 years: immigrants have increasingly gravitated toward “new destinations” and a growing portion are undocumented. In the absence of federal comprehensive immigration reform, states are proposing a patchwork of laws. While some laws encourage immigrant integration, most seek restriction. To understand this trend, this article analyzes Utah as a new immigration destination, exploring its transformation from an inclusive to a restrictive state. It focuses on a major debate: whether to allow unauthorized residents legal driving privileges. Because Utah initiated this law earlier than most, it leads this debate. To explain its evolution, this article analyzes 10 years of legislative debates and articles published on this law. Building on the narrative studies literature, I find that both sides of the immigration debate utilized a public safety and well‐being narrative. However, supporters of the driver license law relied on a “lower mimetic” narrative, characterized by logic and factual arguments. In contrast, their opponents wove a compelling, “apocalyptic” narrative to criticize the law. This narrative indelibly linked immigration to the dangers of crime and terrorism and thus paved the way for the passage of one of the most restrictive immigration laws in the United States.  相似文献

Christchurch urban lawns are dominated by non-native grasses and forbs. However, we document considerable plant diversity; the total number of species encountered in our 327 sampled lawns was 127, although 80 species occurred in <2% of lawns. Seven distinct lawn communities were identified by Two-Way INdicator SPecies ANalysis using occurrence of 47 species that occurred in > 2% of lawns. Our ability to explain variation in species composition was surprisingly good and indicates intensity of lawn maintenance such as frequency of mowing, irrigation, fertiliser, and herbicide use and whether clippings are removed or not plays the major role. Species richness significantly declines with an increase in total area of contiguous lawn, leaf litter cover, the presence of grass clippings, and on loamy soil. Hence, park lawns with coarser management had lower species richness than residential lawns. Native species were more prevalent in well tended residential lawns, where more frequent mowing and removal of clippings or litter build-up diminishes shoot competition or shading. There is tremendous potential for more native species in New Zealand lawns which would contribute substantially to the conservation of endangered lowland herbaceous flora.  相似文献

Ecological momentary assessment (EMA) studies investigate intensive repeated observations of the current behavior and experiences of subjects in real time. In particular, such studies aim to minimize recall bias and maximize ecological validity, thereby strengthening the investigation and inference of microprocesses that influence behavior in real-world contexts by gathering intensive information on the temporal patterning of behavior of study subjects. Throughout this paper, we focus on the data analysis of an EMA study that examined behavior of intermittent smokers (ITS). Specifically, we sought to explore the pattern of clustered smoking behavior of ITS, or smoking ‘bouts’, as well as the covariates that predict such smoking behavior. To do this, in this paper we introduce a framework for characterizing the temporal behavior of ITS via the functions of event gap time to distinguish the smoking bouts. We used the time-varying coefficient models for the cumulative log gap time and to characterize the temporal patterns of smoking behavior, while simultaneously adjusting for behavioral covariates, and incorporated the inverse probability weighting into the models to accommodate missing data. Simulation studies showed that irrespective of whether missing by design or missing at random, the model was able to reliably determine prespecified time-varying functional forms of a given covariate coefficient, provided the the within-subject level was small.  相似文献

Previous research identifies a “great paradox” in attitudes toward environmental regulation: some people close to environmental risk nevertheless oppose environmental regulation for partisan reasons. Does this pattern hold in large survey samples? Unexpectedly, we do not find evidence for it. Instead, we find that Republicans who report higher levels of personal environmental harm also report stronger support for environmental regulation. This pattern holds across varied measurement specifications, and it is weaker for Democrats, suggesting that exposure to environmental harm might directly challenge and change partisan opposition to environmental reform. We present a theory and research agenda that accounts for these “green elephants in the room.” Our work, as we will demonstrate, crosses at least three disciplinary boundaries: social psychology, cultural sociology, and political science. A conceptual replication of results is provided in the Appendices S1 and S2.  相似文献

Misconduct versus honest error and scientific disagreement   总被引:1,自引:0,他引:1  
Researchers sometimes mistakenly accuse their peers of misconduct. It is important to distinguish between misconduct and honest error or a difference of scientific opinion to prevent unnecessary and time-consuming misconduct proceedings, protect scientists from harm, and avoid deterring researchers from using novel methods or proposing controversial hypotheses. While it is obvious to many researchers that misconduct is different from a scientific disagreement or simply an inadvertent mistake in methods, analysis or misinterpretation of data, applying this distinction to real cases is sometimes not easy. Because the line between misconduct and honest error or a scientific dispute is often unclear, research organizations and institutions should distinguish between misconduct and honest error and scientific disagreement in their policies and practices. These distinctions should also be explained during educational sessions on the responsible conduct of research and in the mentoring process. When researchers wrongfully accuse their peers of misconduct, it is important to help them understand the distinction between misconduct and honest error and differences of scientific judgment or opinion, pinpoint the source of disagreement, and identify the relevant scientific norms. They can be encouraged to settle the dispute through collegial discussion and dialogue, rather than a misconduct allegation.  相似文献
