The 1998 floods, which inundated much of Bangladesh, had a major effect on the lives and work of urban slum children. Lack of work opportunities, and beliefs about appropriate roles for young children, meant that the floods did not lead to great increases in workforce entry and in some cases led to a reduction in the opportunities available. Children's domestic work was also affected. Children's paid and domestic work had an important impact on how well households survived during and after the floods. The findings highlight the simultaneously beneficial and harmful nature of much child labour, and are therefore relevant to the dilemmas that face policy makers in this area. The research reported on in this article also has implications for those involved in disaster relief policy making. 相似文献

Abstract: Detecting composite resin upon postmortem examination can be difficult. Ultraviolet illumination has been suggested to ease location of this material; however, this may not be advisable in incineration situations. Understanding of the chemical and physical properties of resin as a function of temperature is an important parameter in identification of this material in incineration circumstances. Twenty-seven discs of resin, Quixx (Dentsply), Filtek Supreme (3 M), and Tetric Ceram (Ivoclar) were prepared and exposed to increasing heating conditions of 200°C–900°C in 100°C increments for 30 min. Analysis was performed with Fourier transform infrared spectroscopy, ultraviolet-visible light spectrophotometry, scanning electron microscopy/energy dispersive X-ray spectroscopy, optical microscopy, and UV illumination. Characterization of the material occurred at each temperature range. The organic components and the fluorescence properties were lost at temperatures above 300°C. The inorganic component remained through 900°C. This information can aid in detection of resin in high temperature circumstances. 相似文献

This article applies theories of legal compliance to analyze the making of this country's first “illegal immigrants”—Chinese laborers who crossed the U.S.‐Canadian and U.S.‐Mexican borders in defiance of the Chinese exclusion laws (1882–1943). Drawing upon a variety of sources, including unpublished government records, I explore the ways in which Chinese laborers gained surreptitious entry into the United States during this period and ask, what explains their mass noncompliance? I suggest that while an instrumental perspective is useful for understanding these border crossings, it overlooks other important determinants of noncompliance: normative values and opportunity structures. Specifically, the exclusion laws were widely perceived by the Chinese as lacking social and moral legitimacy, and thus not worthy of obedience. In addition, the existence of smuggling networks and liberal immigration policies in Canada and Mexico played a critical role in facilitating noncompliance. The article concludes with a discussion about the benefits and challenges of using this theoretical framework to analyze noncompliance in immigration law. 相似文献

This clinically based study asked 165 batterers attending a court-mandated assessment program to quantify a series of behaviors that occurred since being convicted of battering. The behaviors clustered into 2 factors: (1) an Ambivalent Contact Pattern whereby behaviors of batterers were associated with contacting their ex-partner, sending gifts and letters, and watching her without her knowing while harboring conflicting feelings of love, hate, and anger; and (2) a Predatory Contact Pattern whereby the behaviors of batterers were associated with hang up calls, entering her home without permission, threatening or physically causing harm to her while harboring a propensity for abusiveness. Clinicians should assess batterers for predatory thoughts about the estranged partner, and reason for the contact since separation. Presence of stalking behaviors and predatory fantasy is a window to determine repetitive and escalating domestic violence. 相似文献
