We analysed the Chilean university student selection processes, comparing ‘First Generation’ and ‘Continuist’ students, using the Chilean Higher Education population databases (2000–2015). Findings confirm that 60 percent of participants in the selection process are First Generation students. The data registers an increasing self-exclusion phenomenon. Of the students who did not take the selection test after enrolling, 80 percent are First Generation and 18 are enrolled in a selective university, compared to 44 in the Continuist conglomerate. These differences may be explained by cultural capital in the Bourdieu sense, in conjunction with a diversified, massified and marketalised higher education system.  相似文献

In a context of rising violence and long-lasting impunity, in 2008, Mexico's criminal justice system underwent a radical change from an inquisitorial model to an adversarial one, to make it more effective, transparent, and expeditious. The new system tasked judges with publicly determining the admissibility of forensic evidence, as well as assessing its technical quality and probative value—tasks for which they currently receive little to no training. With the aim of contributing to the consolidation of the adversarial model, a comparative framework—in the form of a checklist—of the analysis of fingerprints, DNA samples, and voice recordings was created. To do so, a review of the academic literature, published reports, and guidelines was performed. The collected data were synthesized and submitted to a panel of Mexican judges, who provided feedback on its adequacy. The framework focuses on the steps on which quality assurance of forensic evidence depends, organized in five discrete stages that span from the collection of samples at the scene of a crime to the presentation of evidence at trial, specifying the main technical criteria experts should state to allow a decision maker to examine its accuracy and reliability. Differences and commonalities among the three methods were identified, particularly in terms of how qualitative and quantitative analyses are performed in each. Besides its potential usefulness as an aid for judicial decision-making, the checklist could be a valuable resource for training programs aimed at judges, as well as quality assurance programs.  相似文献

Abstract

Despite shared historical experience and cultural proximity, the Visegrad group (V4) struggles to institutionalise its cooperation through stable mechanisms ensuring internal cohesion and external credibility. This is especially evident in the field of security and defence, which requires a shared strategic vision, in particular, common norms regarding the legitimate use of military force. While in the 1990s the four countries exhibited solidarity and unity in their collective ambition under the narrative of the ‘Return to Europe’, their general perception of security threats and strategic culture prevents deeper integration into a security community.  相似文献

The article analyzes the relationship that exists between electoral campaigns and corruption, studying the case of Mexico. The most common ways and means of practicing and presenting corruption during these electoral processes are described. In addition, the circle of corruption that begins during the electoral processes and continues once in the government is described. In the same sense, the results of an opinion survey in the Metropolitan Zone of Guadalajara (ZMG) on corruption during electoral campaigns are presented. It is concluded that, many times, corruption in the government begins during the electoral stage, so it is important to articulate various strategies and legal instruments to inhibit it from the electoral stage.  相似文献

The purpose of this article is twofold: first, to examine the differences between buyers' and sellers' use of negotiation tactics in face‐to‐face business‐to‐business (B2B) negotiations and second, to explore how negotiators' professed negotiation styles influence buyers' and sellers' use of tactics. The methodology is a multiple case study analysis of eighteen negotiators representing twelve companies in six real‐life buyer–seller negotiations in B2B settings analyzed using qualitative research methods, including both comparative analysis and frequency analysis. We found some difference between buyers' and sellers' use of negotiation tactics, which suggests this question deserves further empirical study. Buyers' and sellers' use of specific tactics differs according to which overall strategy the negotiators chose, and sellers generally use a greater number of negotiation tactics than buyers. The findings challenge previous findings that suggest that B2B negotiations are collaborative and that negotiators communicate in a collaborative manner. The findings also increase our understanding of buyers' and sellers' variable use of tactics in the course of everyday practice as well as the interplay between negotiation tactics and strategies.  相似文献

Young adulthood represents a developmental period with disproportionately heightened risk of losing a job. Young adult unemployment has been linked to increased mental health problems, at least in the short term. However, their possible long-term impacts, often referred as “scarring effects,” have been understudied, possibly underestimating the magnitude of mental health burden that young adult unemployment generates. This longitudinal study examined whether duration of unemployment during young adulthood is associated with later mental health disorders, after accounting for mental and behavioral health problems in childhood. Furthermore, the current study investigated whether childhood neighborhood characteristics affect this association and if so, in what specific functional ways. Data were drawn from a longitudinal study of developmental outcomes in a community sample in Seattle. Data collection began in 1985 when study participants were elementary students and involved yearly assessments in childhood and adolescence (ages 10–16) and then biennial or triennial assessments (ages 18–39; N?=?677 at age 39; 47% European American, 26% African American, 22% Asian American, and 5% Native American; 49% female). The current study findings suggest that duration of unemployment across young adulthood increased mental health problems at age 39, regardless of gender. Childhood neighborhood characteristics, particularly their positive aspect, exerted independent impacts on adult mental health problems beyond unemployment experiences across young adulthood. The current findings indicate a needed shift in service profiles for unemployed young adults—a comprehensive approach that not only facilitates reemployment but also addresses mental health needs to help them to cope with job loss. Further, the present study findings suggest that childhood neighborhoods, particularly positive features such as positive neighborhood involvement, may represent concrete and malleable prevention targets that can curb mental health problems early in life.
