The ingestion of corrosive substances may produce severe burns to the upper aerodigestive tract and stomach, particularly if the pH is greater than 12 or less than two. There is a biphasic age grouping with adult cases most often involving self‐harm and pediatric cases accidental ingestion. Three cases are reported to demonstrate characteristic features following the ingestion of potassium hydroxide, glacial acetic acid and Lysol®, respectively. All deaths were due to the effects of caustic burns to the upper aerodigestive tract, esophagus and stomach with perforation and/or hemorrhage. The extent of injuries in these cases depends on the nature, amount, and concentration of the agent and on the exposure time. A point to note at autopsy is that tissue damage may also occur from postmortem exposure. Typical injuries involve perioral, limb, and trunk burns, with extensive aerodigestive liquefactive/coagulative necrosis causing hemorrhage and perforation. 相似文献

Latent fingerprint deposits on thermal paper sourced from the U.S., China, the U.K., and Australia have been visualized by heating. U.S. and Chinese sourced paper produced two distinct types of fingerprint development. In one type (type 1), the paper dye colors where the deposit is present (as previously reported) and in the other type (type 2) the ‘inverse’ of this gives paper coloring only in areas not coincident with the deposit. Both development types gave identifiable fingerprints, the majority fading within 24 h of heating. Fingerprint development from U.K. and Australian sourced paper was exclusively type 1 and resistant to fading. Temperatures for fingerprint visualization were higher for U.S. paper (64–71°C) and Chinese paper (75–95°C) than for U.K. and Australian sourced paper (43–50°C). Particularly for Chinese sourced paper, these temperatures were within a few degrees of the normal paper color temperature. A mechanism for type 2 fingerprint development is proposed. 相似文献

The field of public administration knows many concepts. By focusing on one such concept, this research shows how definitions can be deceptive, and how typologies unable to capture all dimensions of a concept can blind policy makers and researchers. We concentrate our attention on decentralization. This has been a core concept in the field of public administration for decades. Definitions and typologies of decentralization have flourished. The present study gives an overview. We categorize definitions and analyse their different emphases. Typologies serve to order and compare items, but have themselves become prone to disorder. We provide a meta-analysis of typologies, exposing the wide variety of policy dimensions. Even after aggregation, typologies ignore—and definitions explicitly exclude—certain aspects of decentralization. One such issue is “silent decentralization.” It is characterized by absence of explicit decentralization reform, and thus distinguishes itself mainly by its potential origins: network changes, initiative shifts, policy emphasis developments, or resource availability alterations. Highlighting this particular aspect might well proof useful for other concepts in the field as well. 相似文献

That HIV/AIDS has had an enormous impact on southern Africa in general, and in Botswana in particular, is not in doubt. Numerous studies have documented certain aspects of the problem—high HIV prevalence rates, increasing numbers of orphans and vulnerable children, declining average life expectancy, and a high number of deaths among adults during their most productive years. Scholars have engaged in speculation about the possible impacts that this disease might have on social relationships, economic growth and development, and governance in both the near and the long terms. But these studies are only forecasts of possible futures, not data driven analyses. This study closely examines data available from two agencies in the Botswana civil service, the police and prisons services in an effort to assess, albeit indirectly, any impact that the HIV/AIDS crisis may have had on the workforce. Although the AIDS epidemic in the country as a whole was reflected in the experience of these services, neither agency suffered the devastating effects some feared. 相似文献

This article explores labour market behaviour of members of extended and nuclear households in Suriname. Previous analyses have found that co‐operative childcare opportunities within the extended household increase female labour force participation. Such coordination implies correlated participation decisions, which invalidates standard assumptions made in estimating participation with probits and wages with regressions. We employ a GMM estimation, which allows correlation among household members. We find that extended and nuclear household members are not significantly different in participation propensities, but do differ significantly in wages. We argue that greater home production opportunities in extended households dilute labour market effort and hours, reducing earnings. 相似文献

The modern theory of investment identifies the importance of uncertainty to investment. A number of empirical studies have tested the theory on South African time series, employing political instability measures as proxies for uncertainty. This paper verifies that political instability measures are required in the formulation of the investment function for South Africa. It also establishes that there are distinct institutional factors that influence the uncertainty variable such as property rights and crime levels. We find that rising income and property rights lower political instability, and that rising crime levels are positively related to political instability. The inference is that political instability in South Africa may not represent uncertainty directly, since it is systematically related to a set of determinants. Instead, uncertainty would have to be understood as being related to a broader institutional nexus that in concert may generate uncertainty for investors. The paper highlights the significance of getting institutions right to ensure that uncertainty is kept to a minimum by providing a predictable long-term environment. Stability at a systemic level appears crucial if investment rates are to rise in South Africa and this paper demonstrates that stability in turn is driven by a sound institutional environment that has multiple dimensions. 相似文献

We replicated the study ‘Male circumcision for HIV prevention in young men in Kisumu, Kenya: a randomised controlled trial’ using an epidemiological approach as well as an econometric approach. Both approaches confirmed the 60 per cent protective effect of circumcision reported in the original paper. Similar to the original paper, we found no evidence of heterogeneous treatment effects by age. Contrary to the original study, we found evidence of risk compensation, with circumcised men less likely to stay abstinent (odds ratio 0.79 [95% CI: 0.64, 0.99]) and more likely to have had unprotected intercourse (OR 1.2 [1.1, 1.4]). These findings reinforce the impact of circumcision but highlight behavioural risk. 相似文献

Abstract The present paper attempts to demonstrate how hope theory is conceptually consistent with current positive approaches to sexual offender treatment. Hope theory and its components of goals, pathways thinking, and agentic thinking is reviewed as defined by Snyder and his colleagues. A theoretical relationship exists between the role of hope and many aspects of sexual offending and treatment. Developmental course, attachment style, and the formation and maintenance of coping styles are reviewed as they relate to hope and sexual offending. A framework by which to apply hope theory to pre-treatment, treatment, and more specifically, self-management or relapse prevention for sexual offenders is proposed. Emphasis is placed on the use of techniques that target hope components, particularly in pre-treatment programs. 相似文献

Abstract Traditionally, research on offender profiling has investigated the relationships between offender behaviour and offender characteristics. However, evidence about offender behaviour is not the only evidence available at a crime scene. This study extends previous collaborative research between forensic scientists and psychologists (e.g. Bond & Sheridan, Journal of Forensic Science, 52, 1122–1128, 2007) to investigate how forensic science can assist in the psychological process of offender profiling. Specifically, the potential utility of footwear impression evidence in the task of offender profiling is investigated. Using 155 domestic burglaries, the consistency and homology assumptions underlying offender profiling were tested. Evidence supportive of both assumptions is reported. A multiple regression analysis identified significant relationships between cost of footwear and employment status, age of offender, and the relative deprivation of his/her residence. 相似文献
