Every year thousands of children are discharged from the foster care system and find themselves ill prepared for the responsibility of adulthood. Providing enhanced employment opportunities to both current and former foster care youth will allow them to become economically self-sufficient and therefore have an improved transition from foster care. This Note proposes that states incorporate a foster youth employment program in the one-stop career centers mandated by the Workforce Investment Act. Through this program, foster youth will be provided with the tools they need for success while maintaining control over their own future. 相似文献

Calcified tissues, such as bone and tooth, and some other sample types, such as those containing adhesive, present a challenge to standard extraction protocols. We have developed a lysis reagent, BTA™ lysis buffer, which is designed for use with PrepFiler™ Kit reagents. The BTA™ lysis buffer disrupts calcified tissue matrices and achieves effective extraction of DNA from pulverized bone and tooth samples. In addition, the BTA™ lysis buffer mildly but efficiently extracts DNA from challenging substrates like tape, chewing gum, and cigarette butts and, as with bone and tooth, DNA from these lysates is purified using established PrepFiler™ reagent extraction protocols.We successfully extracted DNA from powdered human bone samples, chewed gum and smoked cigarettes using BTA™ lysis buffer. Extraction yields for bone, gum and cigarette samples tested were consistent and reproducible. This extraction method efficiently removed potential PCR inhibitors from all samples tested, and CT values for the internal PCR control of Quantifiler® Human DNA Quantification Kit were consistent and within the normal range. The DNA extracted from these samples also provided conclusive profiles that were free of PCR artifacts when amplified using the AmpF?STR® Identifiler® PCR Amplification Kit. The protocol is easily adapted for automation. 相似文献

Identification of colorants in pigmented pen inks by laser desorption mass spectrometry 总被引:1,自引:0,他引:1
Pigments are rapidly replacing dyes as colorants in pen and printer inks, due to their superior colors and stability. Unfortunately, tools commonly used in questioned document examination for analyzing pen inks, such as TLC, cannot be used for the analysis of insoluble pigments on paper. Laser desorption mass spectrometry is demonstrated here as a tool for analyzing pigment-based pen inks. A pulsed nitrogen laser can be focused onto a pen stroke from a pigmented ink pen on paper, and positive and negative ions representative of the pigment can be generated for subsequent mass spectrometric analysis. Targeted pens for this work were a set of Uni-ball 207 pigmented ink pens containing blue, light blue, orange, green, violet, red, pink, and black inks. Copper phthalocyanine was identified as the pigment used to make both blue inks. A mixture of halogenated copper phthalocyanines were identified in the green ink. Unexpectedly, the pink ink was found to contain a red pigment, Pigment Red 12, treated with a mixture of water-soluble dyes. Each sample yielded ions representative of the pigments present. 相似文献

Migration and the global media have mixed up all the old cultures into a hybrid brew. How will aging and shrinking societies that need immigrants to survive cope with this new culture? What political philosophy fits this new reality? 相似文献

Abstract: Much has been written on the growth of government expenditures at the national level, focusing on economic variables. Few studies have focused on the growth of spending at the provincial level. Even fewer studies have sought to examine the role of politics in provincial government spending. This paper seeks to fill the gap. It examines the growth of government in Canadian provinces over the last quarter-century, 1960 through 1986, and the role of politics in that growth. Government spending in Canada has grown rapidly at the provincial level over the past quarter-century, more rapidly than at the federal level. The present study develops and tests an econometric model of provincial government expenditure that incorporates economic, social, and political factors. In particular, the influence of the political party in power on provincial government spending is examined. Surprisingly, in most Canadian provinces the political party in power is found to have no significant impact on the level or growth of provincial government spending over the last twenty-five years. Instead, the growth of provincial government spending has been stimulated by the growth of the private sector provincial GDP. The provincial governments have responded to changes in the state of provincial economy and to provincial unemployment by increasing their own level of expenditures. Sommaire: La croissance des dépenses gouvernementales à l'échelon national a fait l'objet de nombreuses analyses, centrées sur des variables économiques. Très peu d'études ont porté sur l'augmentation des dépenses provinciales et, encore moins, sur le rôle joué par la politique à cet égard. Le présent exposé a pour objet de combler cette lacune en examinant la croissance des gouvernements dans les provinces canadiennes au cours du dernier quart de siècle, soit de 1960 à 1986, ainsi que le rôle qu'a joué la politique dans cette croissance. Les dépenses gouvernementales au Canada ont augmenté pendant cette période plus rapidement au niveau des provinces qu'au fédéral. La présente étude élabore et teste un modèle économétrique des dépenses des gouvernements provinciaux qui incorpore des facteurs économiques, sociaux et politiques. En particulier, on y examine l'influence du parti politique au pouvoir sur les dépenses du gouvernement au niveau provincial. Chose surprenante, dans la plupart des provinces, on constate que l'identité du parti politique au pouvoir n'a pas d'effet significatif sur le niveau ou sur la croissance des dépenses des gouvernements provinciaux au cours de ce quart de siècle. C'est plutôt la croissance du produit intérieur brut du secteur privé provincial qui a stimulé l'augmentation des dépenses des gouvernements provinciaux. Ces derniers ont réagi à l'évolution de l'économie provinciale ainsi qu'au chômage provincial en augmentant leur propre niveau de dépenses. 相似文献
