This paper focuses on the recent production of multimodal writing in an indigenous community in Brazil, resulting from the equally recent introduction of literacy. Seeing this form of writing as part of the process of intercultural semiosis and cultural translation, the paper discusses how concepts of local indigenous oral culture and received wisdom interact with the Western concept of writing as the ‘record’ or ‘representation’ of speech, bringing to writing the indigenous notion of cultural ‘enactment’ or ‘performativity’. In an effort to overcome a view of alphabetic writing as semantically only propositional, mimetic and decontextualized, the Kashinawa´ community, by adding visual components to alphabetic texts, appear to transform writing into contextualized performative ‘poiesis’, which simul taneously inaugurates a complex process of semiosis inseparable and only comprehensible from their local cultural perspective.  相似文献

Few academically rigorous accounts exist of the financial activities that sustained the rise of the Provisional Irish Republican Army (PIRA) during the Northern Ireland Troubles. Through a sustained methodology this study seeks to challenge some popular preconceptions and address omissions in the limited historical record. The article explores the organization's evolving financial sophistication by analyzing PIRA's acquisition of capital rather than its arms dealings. Using a new quantitative evaluation, this investigation confronts the prevailing understanding that Irish-American funds were of unrivaled significance to PIRA. It points to an array of domestic fund-raisers that collectively provided the overwhelming bulk of revenue. The study reveals also how PIRA developed an extensive reliance on criminal gangs for its expertise in illegal fund-raising, suggesting that moneymaking schemes were perceived as a necessary but unpopular by-product of the greater political objective. Finally, this article briefly explores how the British authorities sought to interdict PIRA's funding. While the general perception is that little was done to counteract PIRA's financing initiatives in the early phases of its violent campaign, this study, nevertheless, reveals that a subtle counterfinance initiative did take place in Belfast across the 1970s. Overall, the analysis enables a more rounded comprehension of the group's financial resilience.  相似文献

This article reviews the economics literature on the impacts of forced migration. The literature is divided into two parts: impacts on forced migrants and impacts on host communities. Studies exploring the impact of forced migration due to WWII suggest that the long-term impact is often positive. The literature for developing countries suggests that there are serious consequences of forced migration for those forced to migrate. These consequences range from worse labour market outcomes to less consumption smoothing. The impact on host communities seems to be mixed and there are winners and losers. The article provides suggestions for future research.  相似文献

In Germany, both the number of patients treated in forensic psychiatric hospitals and the average inpatient treatment period have been increasing for over thirty years. Biographical and clinical factors, e.g., the number of prior offences, type of offence, and psychiatric diagnosis, count among the factors that influence the treatment duration and the likelihood of discharge. The aims of the current study were threefold: (1) to provide an estimate of the German forensic psychiatric patient population with a low likelihood of discharge, (2) to replicate a set of personal variables that predict a relatively high, as opposed to a low, likelihood of discharge from forensic psychiatric hospitals, and (3) to describe a group of other factors that are likely to add to the existing body of knowledge. Based on a sample of 899 patients, we applied a battery of primarily biographical and other personal variables to two subgroups of patients. The first subgroup of patients had been treated in a forensic psychiatric hospital according to section 63 of the German legal code for at least ten years (long-stay patients, n=137), whereas the second subgroup had been released after a maximum treatment period of four years (short-stay patients, n=67). The resulting logistic regression model had a high goodness of fit, with more than 85% of the patients correctly classified into the groups. In accordance with earlier studies, we found a series of personal variables, including age at first admission and type of offence, to be predictive of a short or long-stay. Other findings, such as the high number of immigrants among the short-stay patients and the significance of a patient's work time before admission to a forensic psychiatric hospital, are more clearly represented than has been observed in previous research.  相似文献

Young adults are more likely to experience intimate partner violence (IPV) than older adults. Little is known about the effect of confiding to others about sustained violence on the mental health of victims. The objective of this study was to explore the links between IPV, help-seeking behaviors and psychological distress by gender in a sample of 233 young couples.Our results indicate the frequency of sustained psychological violence, but not physical violence, was positively associated to distress. For women, seeking help from a greater number of confidents moderated the association between violence and psychological distress. For men, results showed that frequencies of physical and psychological violence were both positively linked to distress. However, unlike women, social support had no buffering effect on men’s distress. These findings increase our understanding of the effects of social support on young adults’ distress following episodes of IPV.  相似文献

The use of bone as a biomarker for chronic and acute exposure to fluoride salts has been suggested, but there are no data published about its use to evaluate lethal intoxication. One hundred and sixty rats were divided into eight groups that received a single oral intubation dose from 0 (control) to 90 mg F/kg as NaF. The animals' time of death was recorded and their femurs were removed for fluoride analysis. Acid-soluble fluoride was determined in the whole bone and on the surface (periosteal), using an ion specific electrode. The data showed a statistically significant relationship between fluoride dose and the number of deaths (P<0.0001). A statistically significant relationship was also found between fluoride dose and fluoride concentration ([F]) in either the whole femur (P<0.0017), on the surface (P<0.0001) or for the ratio periosteal [F]/whole [F] (P<0.0001). However, the [F] on the femur surface was more closely correlated with mortality than that in the whole bone, showing statistically significant differences among the lethal doses and control (P<0.05). The data suggest that the ratio [F] periosteal bone/[F] whole bone, is a biomarker for acute fluoride toxicity.  相似文献

The laborer's physical and mental health, well‐being, and happiness are among the major indicators for measuring each nation's sustainable development. A conflictive and hostile external environment (war zone) poses considerable difficulty and psychological distress to workers and nonworkers. Therefore, working in such a physically dangerous business environment may hurt worker's well‐being and happiness that in turn may reduce the workers' productivity at the workplace. A high level of laborers' productivity in public and private sectors is essential for achieving sustainable development in the long term. Therefore, this paper examines the effects of perceived danger on employees' psychological well‐being in war‐torn Afghanistan, an issue being addressed for the first time. We tested the moderating role of social support from coworkers on this effect in order to have a broader vision of which individuals are healthier and happier in a physically dangerous working environment. Two survey data sets were collected from 190 employees working in various small private and public businesses in Herat, Afghanistan. Our results reveal the negative impact of perceived danger on employees' psychological well‐being and that employees who receive little or no social support from their peers feel the negative effects of a physically dangerous working condition even more acutely.  相似文献

The preservation of teeth that have been exposed to a heat source is a key factor in order to keep their value as evidence. This research paper presents some methods under development for the analysis of dental evidence after exposure to high temperatures; it also establishes age related alterations of young and aged teeth which have been exposed to direct heat. A total of thirty permanent healthy teeth (young=15 and old=15) were submitted to direct heat (n=14) and to a controlled raise of temperature (n=16); they were embedded in polymethylmetacrilate. For the macroscopic study, blocks were cut in half, polished and their surfaces were digitalized. Subsequently, blocks were put in slides, worn away and observed through a photomicroscope. The study of the colorimetric pattern was done by Corel Photo Paint 12.0 and Image J. software. All teeth submitted to the gradual raise of temperature presented a degree of structural damage lower than those exposed to direct heat. The internal surface of young teeth exposed to direct heat showed lines of fracture oblique to the long axis of the tooth; in contrast, a reticular pattern was observed on aged teeth. All teeth exposed to direct heat showed some matte-black coloration areas, while those submitted to a gradual increment of temperature showed a greyish colour in the enamel and a chalky-white in the cementum. By using both thermal treatments in young teeth, the amelodentinal junction was lost, thus preserving the integrity of each tissue. In aged teeth, the separation of this junction was produced because of the breakdown of the dentine. Microscopically, in teeth exposed to direct heat, it was neither possible to differentiate the dentin from the cementum, nor to distinguish the incremental lines of the latter; while in those submitted to a controlled increment of temperature, the corresponding morphology in the tissues was observed. A significant statistical difference was obtained for black colour among young and aged teeth exposed to direct heat, as well as among the means of all colours obtained from the teeth exposed to both treatments. The structural changes observed allow locating a tooth in the studied age groups. Our results show the viability of the applied method for the processing of samples, allowing their preservation as evidence during an indefinite time.  相似文献

Identification of human remains is an imperative element of any medicolegal investigation, and a challenging task for forensic experts and physical anthropologists worldwide. Three hundred adult hands (150 males and 150 females) belonging to south Indian population were studied to investigate sexual dimorphism of the index and ring finger ratio. The index and ring finger ratio is derived by dividing the index finger length by ring finger length. The index and ring finger ratio is found to be higher in females. Index and ring finger ratio < or =0.9700 identified 80% of males for both hands, and ratio >0.9700 identified 74% females for the right hand and 78% for the left hand accurately. This study may prove useful to determine the sex of an isolated hand when it is subjected for medicolegal examination.  相似文献
