Background

Bicycle theft is a serious problem in many countries, and there is a lack of evidence concerning effective prevention strategies. Displaying images of ‘watching eyes’ has been shown to make people behave in more socially desirable ways in a number of settings, but it is not yet clear if this effect can be exploited for purposes of crime prevention. We report the results of a simple intervention on a university campus where signs featuring watching eyes and a related verbal message were displayed above bicycle racks.

Methodology and Principal Findings

We installed durable signs at three locations which had experienced high levels of bicycle theft, and used the rest of the university campus as a control location. Reported thefts were monitored for 12 months before and after the intervention. Bicycle thefts decreased by 62% at the experimental locations, but increased by 65% in the control locations, suggesting that the signs were effective, but displaced offending to locations with no signs. The Odds Ratio for the effect of the intervention was 4.28 (95% confidence interval 2.04–8.98), a large effect compared to other place-based crime prevention interventions.

Conclusions and Significance

The effectiveness of this extremely cheap and simple intervention suggests that there can be considerable crime-reduction benefits to engaging the psychology of surveillance, even in the absence of surveillance itself. Simple interventions for high-crime locations based on this principle should be considered as an adjunct to other measures, although a possible negative consequence is displacement of offending.  相似文献

In 2010, South Africa hosted the first World Cup in soccer ever to take place on the African continent. Twenty years after the fall of Apartheid, South Africa presents a series of fractured and contradictory images to the outside world. It is, on the one hand, an economic powerhouse in sub-Saharan Africa, but on the other hand a society in which socio-economic inequalities have continued to flourish and increase. What can anthropology tell us about contemporary South Africa? As part of an ongoing series in public anthropology, Professor Thomas Hylland Eriksen and Postdoctoral Fellow Sindre Bangstad sat down for a public conversation with Professors John L. and Jean Comaroff in The House of Literature in Oslo, Norway, on 28 September 2010.  相似文献

The objective of this paper is the structural and narrative reconstruction of representations of ‘nature’, ‘wildlife’ and ‘landscape’, held by rural residents of the Dadia Forest Reserve. Data collection involved in-depth interviews. Employing a social representations’ approach, we recovered representational elements that are expected in the case of rural belief systems, such as negative dispositions towards wolves and foxes, as well as elements of an urban adherence, such as nature’s independence. Representational elements refer to visual aspects of the countryside, which seem compatible with the figurative nucleus of the rural idyll. Concerning ‘wildlife’, residents focused on vultures, which comprise the main tourist attraction of the reserve. Scientific knowledge adds to the complexity of the narrative schema, which corresponds to the representation of ‘wildlife’. Interviewees perceived the rural landscape as an interface between the natural and the human-conditioned environment. Our study shows that interviewees make no reference to environmental conservation or quality of life issues, as it could be expected according to relatively wide definitions of the term ‘environmentalism’. Environmental messages reinforced by ecotourism development seem to be recalled primarily in terms of their compatibility with the perceived economic benefit of local people. Despite ecotourism development, representational elements that diverge from a tourist version of ‘nature’, ‘wildlife’ and ‘landscape’ were not pronounced within rural belief-systems. Further interventions within the study area are needed, in order to address a variety of topics under the environmental conservation discourse and raise the environmental awareness of rural residents.  相似文献

A comparative statistical study has been carried out on populations of modern algae, of Precambrian algal microfossils, of the organized elements of the Orgueil carbonaceous meteorite, and of the oldest microfossil-like objects now known (spheroidal bodies from the Fig Tree and Onverwacht Groups of the Swaziland Supergroup, South Africa). The distribution patterns exhibited by the >3000 m.y.-old Swaziland microstructures bear considerable resemblance to those of the abiotic organized elements but rather markedly differ from those exhibited by younger, assuredly biogenic, populations. Based on these comparisons it is concluded that the Swaziland spheroids could be, at least in part, of non-biologic origin; these oldest known fossil-like micro-structures should not be regarded as constituting firm evidence of Archean life.Given at the International Seminar Origin of Life, 2–7 August 1974, Moscow, U.S.S.R.  相似文献

Bdelloid rotifers are mostly known for two peculiarities, continuous parthenogenetic reproduction and dormancy in response to habitat desiccation, a phenomenon named anhydrobiosis. These uncommon traits earned them the names of ‘evolutionary scandals’ and ‘sleeping beauties’, respectively. Relevant aspects of bdelloid biology have recently been described that connect parthenogenesis to anhydrobiosis and that might account for their evolutionary survival in spite of the conservative reproduction. In the present study, I explore recent literature, in the attempt to disentangle the apparent incongruency between the apomictic reproduction and the presumed long-term evolutionary survival of bdelloid species. Recent results remarkably improved our knowledge of bdelloid population biology, genetics, and molecular biology. The most relevant findings concern (i) acquisition of foreign genes through horizontal transfer, (ii) presence of divergent sequences possibly corresponding to ancient gene duplications and (iii) capacity to escape parasites: events that appear to be connected with dormancy. I also address the results of recent studies on the relationships between bdelloids and other rotifers, including acanthocephalans, in an attempt to highlight similarities and differences that should be clarified to better understand phylogenetic relationship among the Rotifera sensu lato.

Cultural homogenization has accompanied many of the most destructive processes of mass displacement during the Twentieth century. Its goal has been to make polity and citizens ethnically and culturally ‘congruent’. This article questions the explanatory power of traditional accounts linking cultural homogenization with industrialization during state-building processes and the emergence of nationalism. It suggests that further attention must be paid to the role of the military as an essential institution in both of these processes. Finally, the ‘egalitarian’ rhetoric and legitimizing rationale underpinning both militarization and cultural homogenization is assessed as a most powerful nationalist tool for imposing new hierarchical structures.  相似文献

Focusing on ethnic Chinese as cultural citizens of the nation, this paper examines national identity in the context of generational change. In so doing, it connects to colonialist conceptions of identity the dominant framework of ethnicity that operates in Malaysia. It argues that this framework allows for the nationalist imagining of ‘Malaysian-Chinese’ as ‘outsiders’. In probing the complex conceptual relationship between ethnicity, national identity and cultural citizenship, this article asks: How does ‘ethnicity’ enter into negotiations over the ‘national’ in the cultural realm? What are the notions of cultural difference and national otherness that operate in the negative dualisms by which nation and ethnicity are defined? How are these dualisms tied to notions of authenticity and cultural citizenship? Using the novel The Harmony Silk Factory by Malaysian author Tash Aw to address these questions, this paper argues the need to rethink current policies and narratives of ethnic and national identity in Malaysia.  相似文献

While racialized youth are often central in debates on citizenship, multiculturalism and belonging, those ascribed as ‘British Chinese’ are constructed as model minorities, lacking a hybridized culture but insulated from racism, and thus invisible in these discussions. This article argues, however, that the model minority discourse is itself a specific form of contemporary racialization that revives ‘yellow peril’ discourses on the capacities of particular ‘Oriental’ bodies. Drawing on ethnographic fieldwork, it examines how young people challenge these constructions, by drawing on popular culture to organize and participate in what they call ‘British Chinese’ and, more provocatively, ‘Oriental’ nightlife spaces. It analyses how through these spaces participants forge a sense of identity that allows them to reimagine themselves as racialized subjects. It demonstrates how these spaces constitute transient sites of experimental belonging, facilitating new cultural politics and social identifications that at once contest reified conceptions of British Chineseness yet also create new exclusions.  相似文献

The actual evidence observed in studies of LEK (local environmental knowledge) is nearly always talk about the environment, or what we refer to as LET (local environmental talk), with the claim of studying LEK usually being built upon the implicit assumption that talk about the environment is the expression of knowledge about the environment. We suggest that it is critically important for researchers to question this assumption, especially when the distinction between LET and LEK is also emphasized by local people themselves. In the case we present here, residents of small fishing villages on the Northern Peninsula of Newfoundland are routinely skeptical about what other local residents say about the environment; that is, they engage in LES (local environmental skepticism). We suggest that paying explicit attention to LES can help distinguish LEK from LET.  相似文献

The central nervous system (CNS) effects of anticholinergic agents have been documented in various patient populations and to varying degrees in case reports, brain-activity surrogates, and computerized cognitive testing. The older patient population with overactive bladder represents a group at increased risk of cognitive impairment and other CNS side effects associated with antimuscarinic agents. The complexity of the effect of anticholinergic agents on CNS function requires an increased level of careful investigation. Studies need to be performed in the at-risk population with multiple, validated tests at clinically prescribed doses in acute and chronic situations. These studies need to take into account the effect of commonly prescribed dosing regimens, with doses selected to represent with equivalent bladder potency. The alterations in the serum levels and parent/metabolite effects contributed by metabolic issues or drug delivery systems require special attention.  相似文献

In this review we discuss recent progress in the development, testing, and clinical evaluation of new vaccines against tuberculosis (TB). Over the last 20 years, tremendous progress has been made in TB vaccine research and development: from a pipeline virtually empty of new TB candidate vaccines in the early 1990s, to an era in which a dozen novel TB vaccine candidates have been and are being evaluated in human clinical trials. In addition, innovative approaches are being pursued to further improve existing vaccines, as well as discover new ones. Thus, there is good reason for optimism in the field of TB vaccines that it will be possible to develop better vaccines than BCG, which is still the only vaccine available against TB.  相似文献

Abstract

Islamophobia bundles religious, ethnic and cultural prejudices together even though a narrow definition of the term flags religion as playing the central part. Calls for decoupling religion from ethnicity and culture appear justifiable: religions are increasingly disconnected from the cultures in which they have been embedded. But established political discourse infrequently makes such distinctions and may go further to racialize cultural and religious attributes of non-Europeans through essentialist framing. Islamophobia becomes a cryptic articulation of race and racism even if overtly it appears as religiously-based prejudice. Islam has been culturalized and racialized by its adherents and antagonists alike. Survey data on attitudes towards Muslims confirm such framing: the most common grounds given for experiencing discrimination was race or ethnic origin; religion and belief system were cited less often. Racialization, race and differential racism have become more endemic to Islamophobesã stigmatizing of Muslims, but to categorize Islamophobes as racists is bad politics.  相似文献

Gregory Bateson was welcomed into Biosemiotics as one of its precursors along with C. S. Peirce and Jacob von Uexküll He certainly endorsed Peirce pragmatic concern with learning as an essential characteristic of mammalian life, and also endorsed von Uexküll’s notion that the fundamental unit of animate existence is organism plus econiche. But he was at odds both with the subjectivism and with the cognitivism that connects Peirce to von Uexküll. Bateson rests his case on information theory which, he believes replaces many metaphysical notions that were the background to Peirce and von Uexküll’s approaches to ‘meaning.’ His idea of cybernetic ‘feedback’ in information circuits or networks yields a new understanding of recursiveness. Yet biofeedback in mammalian interaction had to be wrestled away from technical cybernetics and its thermodynamic rules about information, for the latter payed no attention to ‘meaning’ (“Bioentropy” section). Of the contrasts between Peirce and Bateson, the most significant is that Bateson regards ‘difference’ as primary to perception, while Peirce is concerned with continuity as primary from perception to cognition. This contrast is at the heart of Bateson’s Korzybski Lecture (see “On the Title of ‘Steps’” section), and shows how ‘difference’ in Learning develops orders and levels (see “Memory and Learning” section) leading to different categories of learning. With regard to perception, Bateson argues that the processes of perception do not bind perception to conscious awareness in any exclusive sense. Further, patterns of perception are not bounded by the skin for they include all external pathways along which information can travel. This recursive activity develops ‘agency’ (“Perception and Consciousness” section). We are ourselves interact with living mental ‘things’ but interactions with animate ‘creatura,’ is not the same as the objective interactions we purse in measuring inanimate material ‘things’ (pleroma) (“How Bioentropy Informs Bateson’s Notions of Pleroma and Creatura ” section). The grasping of context in communicative interaction, for example, is unique to creatura (“Context in Recursive Communication” section). Recognition of ‘difference’ occurs through communicative interactions and is meta-physical (without dimension). The pattern of interaction is the ‘thing,’ and ostensive aspects of communication are contextual, inclusive of all ‘external’ aspects vital for interpretation of ‘signals’ between initiators and responders to messages. Towards the end of his life, Bateson’s concerns with non-human conditions of ‘meaning’ and ‘mind’ in nature, resulted in his dropping several of the Peirce’s conditions of semiosis, as he looks at ‘meaning’ without language. He rests his method the propositional order of Peirce’s abduction rather than the latter’s full array of abduction, induction and deduction. Bateson is supported by the Biosemantics of Ruth Millikan, this paper will argue, who also believes that the derivation of meaning in animals through natural signs requires the stripping away of any ‘meaning rationalism’ (“Meaning Rationalism” section). Together they provide joint conclusions about as sign use in the ecosystems of creatura (“Conclusion” section).  相似文献

The deinstitutionalization of psychiatric patients is a deeply cultural as well as political task. It entails the sharing of responsibility for human distress with family and community. Consequently, the locus of social control has also shifted from psychiatric and medical expertise to community and legal institutions. Diagnosis and treatment models must be more compatible with lay explanatory models. This paper explores the various meanings of going mental and being mental in the white, working class, ethnic neighborhood of South Boston. The data are extracted from a study of the impact of deinstitutionalization on a cohort of middle-aged, psychiatric patients discharged from Boston State Hospital in the attempt to return them to community living. Individual, family, and community responses to, and interpretations of, the symptoms of mental distress are discussed. The study indicates that even seriously disturbed individuals are sensitive to cultural meanings and social cues regarding the perception, expression, and content of psychiatric episodes. While madness invariably disenfranchises, it does not necessarily deculturate the individual.  相似文献
