Central American regional integration in science,technology and innovation: a new challenge

In recent years in international cooperation policies and public policies of the Central American (CA) region multilateral mechanisms were generated to form interinstitutional networks that drive science, technology, and innovation (STI) as the engine for regional economic growth. In the agreements social, political, and economic disparity were taken into account in order to stimulate the articulation between actors and potentialize local strengths to generate critical mass on the level of knowledge and build a research core base. The aim of this article is to identify institutional and productive capacities acquired in the countries of the region (CA) that encourage interaction on a national level and create favorable conditions to generate regional agreements to build regional interaction on STI. Results show deficiencies in the linking between public and private agents derived from the limited funds destined to I+D, the insufficient channels of information and the lack of interest of the investigations to respond to priority problems of the region, which weaken links with the productive sector. From there, arise the need to build a joint and collaborative work agenda to consolidated the institutional environment and favors the capacities to absorb knowledge.     

Reflexivity and ethical research practice while interviewing on sexual topics

Reflexivity is a multimodal research feature that relies on the researcher’s subjectivity and self-awareness. This paper discusses uses of reflexivity when carrying out qualitative in-depth interviews on sexual topics. Through extracts of a challenging interview, where the challenge comes in the form of sexualised provocation from one man to another, this paper considers the benefits of using reflexivity to address emerging complexities in the interview process. The discussion focuses on ethical research practice through the lens of three forms of reflexivity: (1) reviewing the values that underpin a research project, with emphasis on the tension between rationality and intuition; (2) emotional self-awareness and self-care; and (3) recognition of the power dynamics in the researcher-participant relationship. Reflexivity promotes an intuition-informed decision-making process as a means to achieve ethical practice and conduct interviews with sensitivity and proficiency.     

A note on glejser's test for heteroscedasticity

Glejser published a test on the residuals of a regression model where the parameters are estimated by OLS that purports to detect “mixed” heteroscedasticity. This note addresses the problem of detecting this type heteroscedasticity from,both a theoretical and pragmatic point of view. We conclude that “mixed” heteroscedasticity cannot be separated from non zero expected errors and thus cannot be detected using Glejser s technique.     

Cut-points to prevent low back injury due to force exertion at work

Force exertion is related to low back injuries (LBI). This paper critically reviews the literature concerning cut-points for back force exertion, presents available guidelines in a concise manner, and identifies areas that need further research. The studies reviewed were grouped according to the criteria used to set the cut-point values. Most often cut-points differ than concur. The approach considering physiological, psychophysical, epidemiological, and biomechanical aspects of back force exertion meets the most known criteria and presents the lowest common denominator of instantaneous load for lifting tasks. Further experimental and epidemiological studies in peak load and cumulative exposure are necessary. Compound indices should also be developed for pushing, pulling, and carrying. Future indices should consider electromyographically determined fatigue, differential viscoelastic properties of tissues, aging, and the cross sectional area of back muscles. We hope that this paper contributes to a more systematic appraisal of back force exertion at work.     

Statistical methods to evaluate health effects associated with major sources of air pollution: a case-study of breathing patterns during exposure to concentrated Boston air particles

Summary.  We conduct a case-study evaluating the source-specific effects of particulate matter on respiratory function. Using a structural equation approach, we assess the effect of different receptor models on the estimated source-specific effects for univariate respiratory response. Furthermore, we extend the structural equation model by placing a factor analysis model on the response to represent the measured respiratory responses in terms of underlying respiratory patterns. We estimate the particulate matter source-specific effects on respiratory rate, accentuated normal breathing and airway irritation and find a strong increase in airway irritation that is associated with exposure to motor vehicle particulate matter.     

Developmental Differences in Infants' Attention to Social and Nonsocial Threats

Research has demonstrated that humans detect threatening stimuli more rapidly than nonthreatening stimuli. Although the literature presumes that biases for threat should be normative, present early in development, evident across multiple forms of threat, and stable across individuals, developmental work in this area is limited. Here, we examine the developmental differences in infants' (4‐ to 24‐month‐olds) attention to social (angry faces) and nonsocial (snakes) threats using a new age‐appropriate dot‐probe task. In Experiment 1, infants' first fixations were more often to snakes than to frogs, and they were faster to fixate probes that appeared in place of snakes vs. frogs. There were no significant age differences, suggesting that a perceptual bias for snakes is present early in life and stable across infancy. In Experiment 2, infants fixated probes more quickly after viewing any trials that contained an angry face compared to trials that contained a happy face. Further, there were age‐related changes in infants' responses to face stimuli, with a general increase in looking time to faces before the probe and an increase in latency to fixate the probe after seeing angry faces. Together, this work suggests that different developmental mechanisms may be responsible for attentional biases for social vs. nonsocial threats.     

A Systems Approach to the Policy‐Level Risk Assessment of Exotic Animal Diseases: Network Model and Application to Classical Swine Fever

Exotic animal diseases (EADs) are characterized by their capacity to spread global distances, causing impacts on animal health and welfare with significant economic consequences. We offer a critique of current import risk analysis approaches employed in the EAD field, focusing on their capacity to assess complex systems at a policy level. To address the shortcomings identified, we propose a novel method providing a systematic analysis of the likelihood of a disease incursion, developed by reference to the multibarrier system employed for the United Kingdom. We apply the network model to a policy‐level risk assessment of classical swine fever (CSF), a notifiable animal disease caused by the CSF virus. In doing so, we document and discuss a sequence of analyses that describe system vulnerabilities and reveal the critical control points (CCPs) for intervention, reducing the likelihood of U.K. pig herds being exposed to the CSF virus.     

CONSTRUCTING RAPE: FEMINISM,CHANGE, AND WOMEN'S EVERYDAY UNDERSTANDINGS OF SEXUAL ASSAULT

The cultural and legal meaning of rape has changed dramatically over the past 30 years as the feminist movement has challenged traditional constructions of sexual violence and offered an alternative construction of the meaning of rape. The transformation of rape into a social problem has brought increased attention to the subject in both popular and academic realms. Despite the growing body of research and theory on sexual violence, little inquiry exists into women s everyday constructions of rape and the degree to which such constructions have been influenced by the feminist movement. This article uses a constructionist framework to examine the everyday understandings of rape held by a diverse sample of women. Data gathered through an open-ended survey instrument were analyzed to reveal both interesting similarities and significant differences in the ways women of different ages, races, and personal histories define and interpret the phenomenon of rape. By examining these data, the extent to which the feminist reconstruction of rape has influenced women s everyday assumptions is examined, and the role of differences among women in perceptions of rape is explored. The findings presented in this article have implications for theories of social problems, for feminist discourse, and for the application of research on rape in applied settings.
