Central to the development of culturally competent violence prevention programs for Hispanic youth is the development of psychometrically sound violence risk and outcome measures for this population. A study was conducted to determine the psychometric properties of two commonly used violence measures, in this case for Mexican American adolescent females. The Conflict Tactics Scales (CTS2) and the Past Feelings and Acts of Violence Scale (PFAV) were analyzed to examine their interitem reliability, criterion validity, and discriminant validity. A sample of 150 low-risk and 150 high-risk adolescent females was studied. Discriminant validity was indicated by the perpetrator negotiation scale and by the victim psychological aggression and sexual coercion scales of the CTS2 and the PFAV. Analysis indicates that the CTS2 scales and the PFAV demonstrate adequate reliability, whereas strong criterion validity was evidenced by eight of the CTS2 scales and the PFAV. 相似文献

"This study of migration and the socioeconomic dynamics of the community of Zoogocho in the state of Oaxaca [Mexico] is an example of what happens in rural areas when Indian-campesinos establish contacts with foreign parts. The penetration of alien socioeconomic and cultural values alters both family and communal structures to such an extent that available resources prove insufficient in competing with the colliding external society. This leads to increasingly more complex movements of the population, the manifestations, causes and consequences of which vary through time not only in the places of origin but also in destinations."

The benzylation of three low molecular weight N,N-disubstituted ethanolamines related to chemical warfare agents (CWAs) to furnish derivatives with improved gas chromatography-mass spectrometry (GC-MS) profiles is described. Due to their low molecular weight and polar nature, N,N-disubstituted ethanolamines are notoriously difficult to detect by routine GC-MS analyses during Organisation for the Prohibition of Chemical Weapons (OPCW) proficiency tests (PTs), particularly in scenarios when they are present at low levels (~1–10 ppm) amidst more abundant interferences. Our studies revealed that the optimal derivatization conditions involved the treatment of the ethanolamine with benzyl bromide in the presence of an inorganic base (e.g., Na2CO3) in dichloromethane at 55°C for 2 h. This optimized set of conditions was then successfully applied to the derivatization of N,N-dimethylethanolamine, N,N-diethylethanolamine and N,N-diisopropylethanolamine present separately at 1 and 10 μg/mL concentrations in a glycerol-rich matrix sample featured in the 48th OPCW PT. The benzylated derivatives of the three ethanolamines possessed retention times long enough to clear the massive glycerol-containing matrix interferences. The protocol herein is introduced as an alternative method for derivatization of these CWA and pharmaceutically important species and should find broad applicability in laboratories where routine forensic analysis is carried out. 相似文献

Most industrialized countries have seen part-time employment as a percentage of total employment increasing in the last decade.
This paper presents the results of a comparative study of part-time employment in Spain and the Netherlands. The project comprises
a legal comparative study of the effectiveness of the normative solutions provided by the Dutch and Spanish legal orders regarding
the protection of part-time workers and the promotion of part-time employment, with special attention paid to the gender dimension
of part-time work in both countries; and an analysis, based on data extracted from the European Community Household Panel
(1995–2001), of the determinants of part-time employment in both countries and an examination of the extent to which part-time
jobs are used as stepping-stones to full-time positions. We have found significant country differences regarding females’
decisions to take part-time jobs. We also have found that, in general, Dutch females are not less likely than their male counterparts
to increase the number of hours they work. However, this applies only to those females who are part of a couple or have children
younger than 12 years. In Spain, females are 2.6 times less likely than their male counterparts to switch from a part-time
to a full-time job. 相似文献

This article contributes to the study of the politics of patronage appointments by creating a typology of patronage roles based on the nature of trust between patrons and appointees and on the skills patrons seek in appointees. Our classification brings together the dispersed literature on patronage roles and can be applied to the study of modalities of patronage across and within countries. We offer preliminary evidence from our study of the politics of patronage appointments in Latin America suggesting that variations in patronage roles can be related to variations in the institutionalization of party systems and to the nature of the links between political actors and voters. Finally, we explore whether the categories identified in our empirical study can be found in other settings. We conclude that our typology can contribute to the study of the impact of modalities of patronage on the quality of public administration and on political governability. 相似文献

Orders of protection are regularly utilized to protect victims of domestic violence as well as their children, by restricting the subject from contact or specific activity with the protected parties. Unfortunately, it is common for the adult protected party to facilitate the violation of these orders in an effort to reconcile with the subject, placing children in danger. This undermines the protection that these orders were intended to offer; without penalty to the protected party. This Note proposes a model statute penalizing any party who knowingly endangers children by facilitating the violation of any order of protection; family or criminal. 相似文献

The history of Cuba during the last 140 years is one of both struggle to preserve national identity and independence and the history of the evolution of the American empire, with its constant craving to appropriate Cuba and of the horrendous methods that it uses today to hold on to world domination. Prominent Cuban historians have dealt in depth with these subjects in different periods and in various excellent books that deserve to be readily available to our compatriots. These reflections are addressed especially to the new generations with the aim of helping them learn about very important and decisive events in the destiny of our homeland. 相似文献
