Violence is a public health concern faced on a daily basis by transgender women. Literature has documented how it adversely affects quality of life and health and in some instances leads to homicide. Considering the lack of research documenting the experiences of violence among transgender women, the objective of this article was to explore manifestations of violence among this population in Puerto Rico. The data presented in this article are part of a larger study on transgender/transsexual health in Puerto Rico. For the purpose of this article we focus on the quantitative data analysis. Participants (N = 59 transgender women) were recruited via respondent driven sampling. Implications and specific recommendations are discussed in light of these findings. 相似文献

This article describes the harassment patterns and the risk profile in trans people living in Spain. A sample of 212 trans persons, aged 10–62, participated in this cross-sectional study. Results showed a high percentage of harassment (59.9%) and frequency of daily harassment (12.6%), especially verbal attacks (59%) that occurred in public spaces (49.1%) and within educational contexts (46.2%). Harassment is more prevalent in trans women than men. Those who disclose their gender identities at a younger age experience higher percentages and frequency of harassment than those who disclose at an older age. They also suffer more harassment of different types. The risk profile of harassment indicates that older trans women are more likely to suffer harassment than younger ones, and the risk decreases each year they delay their gender identity disclosure. The elimination of transphobic attitudes and the promotion of gender justice should be priority strategies in Spain. 相似文献

Online Bin Stretching is a semi-online variant of bin packing in which the algorithm has to use the same number of bins as an optimal packing, but is allowed to slightly overpack the bins. The goal is to minimize the amount of overpacking, i.e., the maximum size packed into any bin.We give an algorithm for Online Bin Stretching with a stretching factor of 1.5 for any number of bins. We build on previous algorithms and use a two-phase approach. However, our analysis is technically more complicated and uses amortization over the bins with the help of two weight functions. 相似文献

The use of the area under the receiver-operating characteristic, ROC, curve (AUC) as an index of diagnostic accuracy is overwhelming in fields such as biomedical science and machine learning. It seems that a larger AUC value has become synonymous with a better performance. The functional transformation of the marker values has been proposed in the specialized literature as a procedure for increasing the AUC and therefore the diagnostic accuracy. However, the classification process is based on some regions (classification subsets) which support the decision made; one subject is classified as positive if its marker is within this region and classified as negative otherwise. In this paper we study the capacity of improving the classification performance of univariate biomarkers via functional transformations and the impact of this transformation on the final classification regions based on a real-world dataset. Particularly, we consider the problem of determining the gender of a subject based on the Mode frequency of his/her voice. The shape of the cumulative distribution function of this characteristic in both the male and the female groups makes the resulting classification problem useful for illustrating the differences between having useful diagnostic rules and obtaining an optimal AUC value. Our point is that improving the AUC by means of a functional transformation can produce classification regions with no practical interpretability. We propose to improve the classification accuracy by making the selection of the classification subsets more flexible while preserving their interpretability. Besides, we provide different graphical approximations which allow us a better understanding of the classification problem. 相似文献

Burnout has been considered important to understanding the well-being of social workers and the quality of the services they render. Despite the ample international usage of the Maslach Burnout Inventory, its psychometric properties have come into question and alternative models of measuring the inventory have been suggested. The purpose of this study was to examine the psychometric properties and the applicability of a Spanish version of the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) in an incidental sample of 947 social workers. Three alternative models of the MBI-HSS were tested for the purpose of identifying the most suitable model for measuring burnout in Spain. The confirmatory factor analysis supported the theory that the model of three correlated factors was superior to alternative models of one and two factors. The structure of three factors (emotional exhaustion, depersonalization, and personal accomplishment) and 19 items showed the best adjustment and a suitable internal consistency of the dimensions of the MBI-HSS. These findings demonstrate that the MBI-HSS has validity and reliability acceptable for measuring burnout in social workers, providing valuable information to the managers of social services in order to reduce burnout among social workers. The limitations of the study and recommendations for future investigation are emphasized. 相似文献

In this article, we analyse the possibility of extending the Moulin theorem to Condorcet voting correspondences. Moulin (1988)
established that every Condorcet voting function suffers from the No Show Paradox, or Abstention Paradox, which means that
in some voting situations some voters would achieve a better result by abstaining (in other words, could manipulate the election
by abstaining). This problem is similar to that of extending the Gibbard–Satterthwaite theorem on voting manipulation through
casting an insincere ballot to voting correspondences. The main result of the paper states that for every Condorcet voting
correspondence there are situations in which every optimistic or pessimistic voter with some preferences could manipulate
the election by abstaining. Another result states, by counterexample, that some Condorcet voting correspondences are free
from the Abstention Paradox from the point of view of other types of voters. 相似文献

There exist an increasing number of studies that demonstrate the necessity to evaluate the processes which characterize a program and guarantee its implementation and evaluation. This paper deals with the implementation of a program designed to improve the acculturation of immigrant families in Spain (EU). Implementation followed a process that has proved successful in other settings, but is being applied here for the first time. Qualitative and quantitative measures are employed to assess each stage of implementation, with a particular emphasis on fidelity to program design. The intent was to guide effective revision of the program, and to establish it in a form that can be implemented on a larger scale. 相似文献
