A satisfação vital: sua relação com o preconceito, a identidade nacional, a autoestima e o bem-estar material, em imigrantes

El propósito de esta investigación fue estudiar la relación de la satisfacción vital con varios factores psicosociales corrientemente vinculados a los procesos de migración internacional. En concreto, este estudio exploró la relación de la satisfacción vital - componente cognitivo del bienestar subjetivo - con las variables prejuicio grupal percibido, discriminación personal percibida, autoestima global personal, identidad nacional y bienestar material percibido. La investigación, de tipo empírico y cuantitativo, se realizó a través de un muestreo no probabilístico con inmigrantes colombianos en varias ciudades del Ecuador (N = 185). Confirmando las hipótesis, se halló una relación positiva entre la satisfacción vital, el bienestar material percibido y la autoestima. Se confirmó así mismo una relación negativa entre la satisfacción vital, la discriminación personal percibida y la identidad nacional. Estas mismas variables; la autoestima, el bienestar material percibido, la discriminación personal percibida y la identidad nacional, emergieron como predictoras de la satisfacción vital. No se confirmó, en cambio, la relación negativa hipotetizada entre la satisfacción vital y el prejuicio grupal percibido. Se hace un análisis de dichos resultados desde la literatura psicosocial.O propósito desta pesquisa foi estudar a relação da satisfação vital com vários fatores psicossociais correntemente vinculados aos processos de migração internacional.

Specifically, this study explored the relationship between life satisfaction-a cognitivedimension of subjective well-being- and perceived group prejudice, perceived personal discrimination, global personal self-esteem, national identity and perceived material well- being. The research, of empirical quantitative type, was conducted with a non-probabilistic sample of Colombian migrants at several cities of Ecuador. As expected, the hypothesis that life satisfaction was positively related to self -esteem and perceived material well-being was confirmed. Also, a negative correlation was confirmed between life satisfaction, perceived personal discrimination and national identity. Results show that the variables self-esteem, perceived material well-being, perceived personal discrimination and national identity are significant predictors of life satisfaction. Findings didn´t confirm the expected negative association between life satisfaction and perceived group prejudice. Results are analyzed from a psychosocial perspective

So you call that research? : mending methodological biases in strategy and organization departments of top business schools

We believe that all strategy and organization (SO) scholars should be able to decide for themselves whether to specialize in certain parts of the knowledge cycle or adopt a broader, multi-method view on the scientific process. In a situation of ―methodological pluralism‖, individuals might choose to contribute to the construction of new administrative theories by means of qualitative works like case studies, ethnographies, biographies, or grounded theory studies (e.g., see Denzin and Lincoln, 2000). Others could then specialize in testing these theories by means of experiments, surveys, or longitudinal econometric studies (e.g., see Lewis-Beck, 1987-2004). Again others could combine both approaches in Herculean attempts to conduct high-impact, integrative research with the potential to change the way we understand the field as a whole

A Method of Drusen Measurement Based on the Geometry of Fundus Reflectance

BACKGROUND: The hallmarks of age-related macular degeneration, the leading cause of blindness in the developed world, are the subretinal deposits known as drusen. Drusen identification and measurement play a key role in clinical studies of this disease. Current manual methods of drusen measurement are laborious and subjective. Our purpose was to expedite clinical research with an accurate, reliable digital method. METHODS: An interactive semi-automated procedure was developed to level the macular background reflectance for the purpose of morphometric analysis of drusen. 12 color fundus photographs of patients with age-related macular degeneration and drusen were analyzed. After digitizing the photographs, the underlying background pattern in the green channel was leveled by an algorithm based on the elliptically concentric geometry of the reflectance in the normal macula: the gray scale values of all structures within defined elliptical boundaries were raised sequentially until a uniform background was obtained. Segmentation of drusen and area measurements in the central and middle subfields (1000 μm and 3000 μm diameters) were performed by uniform thresholds. Two observers using this interactive semi-automated software measured each image digitally. The mean digital measurements were compared to independent stereo fundus gradings by two expert graders (stereo Grader 1 estimated the drusen percentage in each of the 24 regions as falling into one of four standard broad ranges; stereo Grader 2 estimated drusen percentages in 1% to 5% intervals). RESULTS: The mean digital area measurements had a median standard deviation of 1.9%. The mean digital area measurements agreed with stereo Grader 1 in 22/24 cases. The 95% limits of agreement between the mean digital area measurements and the more precise stereo gradings of Grader 2 were -6.4 % to +6.8 % in the central subfield and -6.0 % to +4.5 % in the middle subfield. The mean absolute differences between the digital and stereo gradings 2 were 2.8 +/- 3.4% in the central subfield and 2.2 +/- 2.7% in the middle subfield. CONCLUSIONS: Semi-automated, supervised drusen measurements may be done reproducibly and accurately with adaptations of commercial software. This technique for macular image analysis has potential for use in clinical research

Split Tickets? On the Strategic Allocation of Presidential Versus Vice Presidential Visits in 2016

This article analyzes the strategic allocation of presidential campaign visits in 2016. In particular, we test whether each campaign disproportionately targeted its presidential versus vice presidential candidates’ visits toward voters with whom they shared a salient demographic or political characteristic. Our purpose in doing so is to discern whether—and, if so, among which groups—the campaigns perceived the candidates as having a strategic advantage in appealing to affiliated voters. To this end, we analyze an original database of 2016 campaign visits that includes local population characteristics for each host site. Our results indicate that each ticket’s visits were highly coordinated across states, but frequently divergent within states. At the substate level, we find several systematic differences in the populations visited by presidential versus vice presidential candidates—in some cases aligning with a candidate’s personal characteristics. We discuss these findings’ implications with respect to campaign strategy and vice presidential selection

Communication and cross-examination in court for children and adults with intellectual disabilities: A systematic review

Courts in England, Wales and Northern Ireland have identified children and adults with intellectual disabilities (ID) as vulnerable witnesses. The call from the English Court of Appeal is for advocates to adjust questioning during cross-examination according to individual needs. This review systematically examined previous empirical studies with the aim of delineating the particular communication needs of children and adults with ID during cross-examination. Studies utilising experimental methodology similar to examination/cross-examination processes, or which assessed the communication of actual cross-examinations in court were included. A range of communication challenges were highlighted including: suggestibility to leading questions and negative feedback; acquiescence; accuracy; and understanding of court language. In addition, a number of influencing factors were identified, including: age; IQ level; question styles used; recall memory; and delays. This review highlights the need for further research using cross-examination methodology and live practice, that take into consideration the impact on communication of the unique environment and situation of the cross-examination process
