‘We Are All the Same,We All Are Mestizos’: Imagined Populations and Nations in Genetics Research in Colombia

In Colombia, as in other Latin American countries, current population genetics research is based on the understanding that Colombians constitute a mestizo nation, given the admixture process that took place between Africans, Amerindians, and Europeans during colonial times. The mestizo is a pervasive category used by geneticists to conduct, organise, and publish research studies that deal with the continent's peopling process and the genetic makeup of its contemporary population(s). It is also the dominant imaginary for the Colombian population and a key nation-building ideology. By tracing how this category moves and is used across four Colombian genetics laboratories, it is possible to discern that despite its apparently clear-cut boundaries, the mestizo is contingent, contested, and flexible, allowing for multiple understandings and usages. This flexibility and multiplicity are visible in the quantification of genetic ancestry, the divisions of geographical location, and the understanding of gender. Such understandings allow one to think about a homogeneous nation (inclusive) that is simultaneously heterogeneous (exclusive); they provide multiple but not necessarily contradictory possibilities of being mestizo, allowing the coexistence of images of the nation that could otherwise seem contradictory; and they permit navigation around contested terms such as race, while simultaneously thinking of mixed races or racialised individuals. Finally, these flexible and multiple constructions of the mestizo (re)produce various subjects as ‘other’, whether they are women, the Indigenous, the black/dark, or the poor.     

Body checking and associated cognitions among Brazilian outpatients with eating disorders and nonpsychiatric controls

This work aims to compare in patients with anorexia nervosa, bulimia nervosa, and control subjects: (a) body checking types, frequency, and parts; (b) prevalence of body avoidance and the most checked body parts; (c) body checking cognitions. Eighty-five outpatients with eating disorders (ED) and 40 controls filled out validated body checking and cognition questionnaires. ED patients, especially bulimia nervosa, check their bodies more than do the control subjects. The most checked area was the belly. The most frequent means of body checking was mirror checking, while the most avoided was weighing. The reasons that participants in the various study groups check their bodies seem to differ. Given the importance of body checking in the etiology and maintenance of EDs, it is important that clinicians consider this behavior, as well as the factors that lead to checking/avoidance in the different eating disorder subtypes, so that treatment may be more specific.     

Influencia de la imitación y la comprensión en la adquisición del lenguaje en niños deficientes: dos experimentos basados en un diseño de líneas de base múltiple y control concurrente

RESUMEN

En este trabajo se exponen dos experimentos relacionados con algunos aspectos de la adquisición y desarrollo del pre-lenguaje y primeras etapas del lenguaje funcional, tanto comprensivo como expresivo, con niños deficientes no-verbales. Las autoras parten del programa de Kent “Language Acquisition Program for the Retarded or Multiply Impaired”, y utilizan un diseño experimental de líneas de base múltiples y control concurrente. Los resultados confirman en gran parte la hipótesis según la cual la imitación vocal y el lenguaje comprensivo son dos repertorios básicos para el lenguaje expresivo, concluyendo que el programa adaptado de Kent es un instrumento válido para la enseñanza de diversos aspectos del lenguaje y que la técnica de control concurrente parece ser una buena alternativa en aquellos casos en que el diseño experimental intrasujeto no permite la reversión de las condiciones experimentales.     

Estructura social y conductas de saludo en dos especies de babuinos

Resumen

Independientemente de la proximidad taxonómica, dentro del género Papio existen distintas formas de estructura social. Al mismo tiempo se encuentran diferencias cuantitativas y cualitativas en los repertorios de conducta de las dos especies estudiadas (P. hamadryas y P. cynocephalus), concretamente en los movimientos de salutación.

Se buscó una relación entre dichas estructuras sociales y los respectivos movimientos de saludo que aparecían como característicos de cada especie. La estructura social podría modificarse rápidamente por las presiones ambientales, por lo que serían necesarios nuevos repertorios conductuales en consonancia con el cambio y al mismo tiempo que éste.

Al menos en niveles tan altos de la escala evolutiva, los individuos son capaces de organizar sus conductas según su posición respecto al conjunto del grupo y adecuarlas para acceder a los distintos nichos sociales. Por tanto, no es posible adscribir a la conducta una función exclusiva, sino que dependería de la idiosincrasia individual y de los distintos escalones sociales característicos de una determinada estructura social.     

Universalidad de la expresión emocional e inferencia correcta: Una contestación a Iglesias y cols. (1984)

Resumen

El articulo revisa las críticas que Iglesias y cols. (1984) hacen a otro trabajo (Valle-Inclán, 1983) y concluye que no hay lugar para la critica. La controversia está alrededor del número de patrones faciales de la emoción universales. En mi articulo anterior se defendía que la evidencia sólo permite hablar de dos grandes patrones universales de la expresión facial de las emociones, mientras que Iglesias y col., en la línea de muchos autores, defienden que se pueden defender más patrones faciales universales.     

Green construction and energy training program for at‐risk individuals: a case study

Training individuals who are at risk of unemployment/underemployment to increase their employability is a mission of many nonprofit agencies. These training programs, often supported by government funding, attempt to reduce these individuals’ reliance on government assistance. The purpose of this study is to obtain hard data and an in‐depth understanding about the factors that contribute to the success of the Green Construction training program. The methodology used is a multimethod, multimeasure approach, which provides a reasonably robust triangulation of results. The findings indicate that the program is successful because it has good participant retention, knowledge gain, and placement rates.     

Predictive Criterion-Related Validity of Observer Ratings of Personality and Job-Related Competencies Using Multiple Raters and Multiple Performance Criteria

The purpose of this study was to assess the predictive validity of observer ratings of personality and job-related competencies in a selection setting. Based on ratings from multiple raters of both the predictors and the criteria in a sample of MBA students, results indicated that observer ratings of Conscientiousness, Emotional Stability, leadership, and interpersonal skills predicted work performance, team performance, and academic performance. For work performance and team performance, a composite of the four predictors had incremental predictive validity over general mental ability, even after controlling for how well the rater knew the ratee.     

Authentic leadership and its relationships with work engagement and organizational citizenship behaviors in military units: The role of identification as a mediating variable

The objective of the study is to explore the relationship of authentic leadership with work engagement and organizational citizenship behaviors (OCB) in military units, measuring the mediating effect of personal identification with the leader and social identification with the military unit. We used the Structural Equation Modeling (SEM) technique to analyze data from a sample of 225 Spanish military troops. The results showed that social identification with the military unit influenced the relationship of authentic leadership with the outcome variables.
