Comentarios a la Ley Simpson-Rodino

Para la relación México-Estados Unidos la reciente aprobación de la Ley Simpson-Rodino constituye un elemento más para agudizar y tensificar la ya deteriorada relación bilateral. Su principal objetivo es controlar de manera más efectiva el flujo de trabajadores ilegales que, de acuerdo a la opinión pública norteamericana, constituye una amenaza para su sociedad. Con la aplicación de esta ley, plantean que se recuperará el control de sus fronteras

Competencias profesionales y su desarrollo mediante aprendizaje-servicio en la universidad: perspectiva de los empleadores

Introducirse en el mundo laboral es costoso y uno de los primeros obstáculos es el déficit competencial que, en ocasiones, presentan los universitarios. Para subsanar el exceso de una teoría descontextualizada, el EEES (Espacio Europeo de Educación Superior) ha auspiciado un cambio metodológico que fomenta una docencia más práctica, ya que el aprendizaje más efectivo es activo y está conectado con la experiencia. De este modo, la enseñanza universitaria se enfoca, entre otros aspectos, en la consecución de resultados de aprendizaje en forma de competencias asociadas al mercado laboral. En este contexto se están ensayando en la universidad [española] metodologías más prácticas y aplicadas, entre ellas, el Aprendizaje-Servicio. El objetivo de este trabajo es conocer si para los empleadores participantes en nuestro estudio, los universitarios que participan en actividades de Aprendizaje-Servicio desarrollan el perfil competencial que buscan, haciéndoles candidatos más atractivos en los procesos de selección, mejorando en consecuencia su empleabilidad. Para ello, se desarrolló una investigación cualitativa genérica. Se realizaron tres grupos focales en los que participaron por muestreo intencional trece empleadores de egresados de distintas facultades de la universidad, pertenecientes a distintos sectores. La guía temática incluía preguntas sobre las competencias más demandadas por los empleadores, el Aprendizaje-Servicio y su influencia en el perfil profesional. La transcripción textual fue analizada mediante análisis de contenido inductivo por dos investigadores. En el apartado de resultados y discusión se constató que, para los empleadores consultados, los alumnos que participan en actividades de Aprendizaje- Servicio en la universidad, desarrollan algunas de las competencias profesionales más demandadas en el mundo laboral, incidiendo positivamente en su empleabilidad.Entering the labour force is onerous and one of the first obstacles is, on occasion, the competence shortcomings of university students. To correct the excess of a decontextualized theory, the EHEA (European Higher Education Area) has sponsored a methodological change that encourages more practical teaching, since the most effective learning is active and connected with experience. In this way, university teaching focuses, among other aspects, on achieving learning results in the form of competences associated with the labour market. In this context, more practical and applied methodologies are being tested at the university, including Service-Learning. The objective of this study is to find out whether, for the employers participating in our study, the university students who participate in these Service-Learning activities develop the competency profile they are looking for, making them more attractive candidates in the selection processes, consequently improving their employability. Generic quantitative research has been carried out. A purposive sampling of the employers of graduates from different university faculties was adopted. Three focal groups were formed using a topic guide, which addressed: the professional competences most demanded by employers; the repercussion of the teaching focus on employability; the social involvement capacity of their employees; Service-Learning and its influence on professional profile. 13 employers from different fields participated. Audio clips of the focal groups were recorded and their transcription was analysed by two researchers using content analysis. In the view of the employers consulted, students who participate in Service-Learning activities at the university develop some of the most in-demand professional competences, which positively affect their employability

Analysis of Y chromosome lineages in native South American population

Abstract. The present work tries to identify both the evolutionary footprints and the origin of native population of Argentina using 26 SNPs and 11 STRs of the Y chromosome. A total of 34 samples from 3 different native population (Kolla, Mapuche, Diaguitas) from 5 different regions were analysed.

Onstage and off: The shifting relevance of gender in women’s prisons

uncorrected proofEven though international research on men’s prisons is no longer oblivious to gender, approaches to women’s prisons have tended to be more gender-bound as a whole. Besides having informed a specific reflexive agenda of representation, the angle of gender has presided to most research issues as an analytical overall parti pris: from the gendered nature of prison regimes to the gendered character of prison cultures, socialities and ‘pains of imprisonment’. This more ‘gendercentric’ agenda is however becoming more diversified for theoretical and empirical reasons alike. These involve a recognition of the diversity of women prisoners’ experiences and identities, and an attention to a wider variety of aspects of carceral life. Drawing on field approaches to the Portuguese carceral world spanning three decades, I propose to take this debate further by focusing on contextual shifts in the actual saliency of gender as a category of identity and social life in women’s prisons.(undefined)(undefined)info:eu-repo/semantics/publishedVersio

Uniparental markers of contemporary Italian population reveals details on its pre-Roman heritage.

BACKGROUND: According to archaeological records and historical documentation, Italy has been a melting point for populations of different geographical and ethnic matrices. Although Italy has been a favorite subject for numerous population genetic studies, genetic patterns have never been analyzed comprehensively, including uniparental and autosomal markers throughout the country. METHODS/PRINCIPAL FINDINGS: A total of 583 individuals were sampled from across the Italian Peninsula, from ten distant (if homogeneous by language) ethnic communities--and from two linguistic isolates (Ladins, Grecani Salentini). All samples were first typed for the mitochondrial DNA (mtDNA) control region and selected coding region SNPs (mtSNPs). This data was pooled for analysis with 3,778 mtDNA control-region profiles collected from the literature. Secondly, a set of Y-chromosome SNPs and STRs were also analyzed in 479 individuals together with a panel of autosomal ancestry informative markers (AIMs) from 441 samples. The resulting genetic record reveals clines of genetic frequencies laid according to the latitude slant along continental Italy--probably generated by demographical events dating back to the Neolithic. The Ladins showed distinctive, if more recent structure. The Neolithic contribution was estimated for the Y-chromosome as 14.5% and for mtDNA as 10.5%. Y-chromosome data showed larger differentiation between North, Center and South than mtDNA. AIMs detected a minor sub-Saharan component; this is however higher than for other European non-Mediterranean populations. The same signal of sub-Saharan heritage was also evident in uniparental markers. CONCLUSIONS/SIGNIFICANCE: Italy shows patterns of molecular variation mirroring other European countries, although some heterogeneity exists based on different analysis and molecular markers. From North to South, Italy shows clinal patterns that were most likely modulated during Neolithic times

Evaluation of appendicitis risk prediction models in adults with suspected appendicitis

Background Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis. Methods A systematic search was completed to identify all existing appendicitis risk prediction models. Models were validated using UK data from an international prospective cohort study that captured consecutive patients aged 16–45 years presenting to hospital with acute RIF in March to June 2017. The main outcome was best achievable model specificity (proportion of patients who did not have appendicitis correctly classified as low risk) whilst maintaining a failure rate below 5 per cent (proportion of patients identified as low risk who actually had appendicitis). Results Some 5345 patients across 154 UK hospitals were identified, of which two‐thirds (3613 of 5345, 67·6 per cent) were women. Women were more than twice as likely to undergo surgery with removal of a histologically normal appendix (272 of 964, 28·2 per cent) than men (120 of 993, 12·1 per cent) (relative risk 2·33, 95 per cent c.i. 1·92 to 2·84; P < 0·001). Of 15 validated risk prediction models, the Adult Appendicitis Score performed best (cut‐off score 8 or less, specificity 63·1 per cent, failure rate 3·7 per cent). The Appendicitis Inflammatory Response Score performed best for men (cut‐off score 2 or less, specificity 24·7 per cent, failure rate 2·4 per cent). Conclusion Women in the UK had a disproportionate risk of admission without surgical intervention and had high rates of normal appendicectomy. Risk prediction models to support shared decision‐making by identifying adults in the UK at low risk of appendicitis were identified

Averting biodiversity collapse in tropical forest protected areas

The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon¹⁻³. With deforestation advancing quickly, protected areas are increasingly becoming final refuges for threatened species and natural ecosystem processes. However, many protected areas in the tropics are themselves vulnerable to human encroachment and other environmental stresses⁴⁻⁹. As pressures mount, it is vital to know whether existing reserves can sustain their biodiversity. A critical constraint in addressing this question has been that data describing a broad array of biodiversity groups have been unavailable for a sufficiently large and representative sample of reserves. Here we present a uniquely comprehensive data set on changes over the past 20 to 30 years in 31 functional groups of species and 21 potential drivers of environmental change, for 60 protected areas stratified across the world’s major tropical regions. Our analysis reveals great variation in reserve ‘health’: about half of all reserves have been effective or performed passably, but the rest are experiencing an erosion of biodiversity that is often alarmingly widespread taxonomically and functionally. Habitat disruption, hunting and forest-product exploitation were the strongest predictors of declining reserve health. Crucially, environmental changes immediately outside reserves seemed nearly as important as those inside in determining their ecological fate, with changes inside reserves strongly mirroring those occurring around them. These findings suggest that tropical protected areas are often intimately linked ecologically to their surrounding habitats, and that a failure to stem broad-scale loss and degradation of such habitats could sharply increase the likelihood of serious biodiversity declines.Keywords: Ecology, Environmental scienc
