Latin American Psychology in the Interamerican Journal of Psychology in the 1990's

This paper reviews 119 articles by Latin American psychologists, which have been published between 1990–1998 in the Revista Interamericana de Psicologia/Interamerican Journal of Psychology (RIP, ISP). As the official publication of the Interamerican Society of Psychology, the journal plays a prominent role, especially in Latin American psychology. It is concluded that Latin American psychologists have been active in many research areas and are seeking solutions for many pressing societal problems. While interested in a variety of general theoretical issues, Latin American psychologists have focused above all on applied studies.     

Nonparametric Tail Copula Estimation: An Application to Stock and Volatility Index Returns

In this study, we measure asymmetric negative tail dependence and discuss their statistical properties. In a simulation study, we show the reliability of nonparametric estimators of tail copula to measure not only the common positive lower and upper tail dependence, but also the negative “lower–upper” and “upper–lower” tail dependence. The use of this new framework is illustrated in an application to financial data. We detect the existence of asymmetric negative tail dependence between stock and volatility indices. Many common parametric copula models used in finance fail to capture this characteristic.     

Structural changes in multivariate regression models

This study generalizes the work of chin choy and Broemeling (1980) who investigated the change in the regression parameters of univariate linear models.

The marginal posterior distributions of the change point, the regression matrices,and the precision matrix are found with the use of a proper multivariate normal-Wishart distribution for the parameters of the model.

A numerical study is undertaken in order to gain some insight into the effect that changes in sample size and certain parameter values have on these marginal posterior distributions.     

The Power of Imagination in Transnational Mobilities

At the roots of many travels to distant destinations, whether in the context of tourism or migration, are historically laden and socioculturally constructed imaginaries. People worldwide rely on such imaginaries, from the most spectacular fantasies to the most mundane reveries, to shape identities of themselves and others. These unspoken representational assemblages are powerful because they enact and construct peoples and places, implying multiple, often conflicting, representations of Otherness, and questioning several core values multicultural societies hold, by blurring as well as enforcing traditional territorial, social, and cultural boundaries. What are the contours of power, agency, and subjectivity in imaginaries of transnational mobility and the intersecting social categories those visions both reify and dissolve? Ethnographic studies of human (im)mobility provide an innovative means to grasp the complexity of the global circulation of people and the world-making images and ideas surrounding these movements. As a polymorphic concept, mobility invites us to renew our theorizing, especially regarding conventional themes such as culture, identity, and transnational relationships. This article critically analyzes some preliminary findings of an ongoing multisited research project that traces how prevalent imaginaries of transnational tourism to and migration from the “global South” are (dis)connected. I suggest anthropology has unique contributions to make to the current debate in the social sciences by ethnographically detailing how mobility is a contested ideological construct involving so much more than mere movement.     

The Politics of Temporality: An Analysis of Leftist Youth Politics and Generational Contention

Based on focus groups and in-depth interviews with young leftist political party activists in Uruguay, this article analyzes the dilemmas faced by young people as they use images from the past to interpret and orient their situation in the present and their aspirations for the future. They are the heirs to a highly romantic image of what it means to be a political activist on the Left; in this sense, the shadow of the radical Sixties and the omnipresent image of armed struggle and military dictatorship define them. But the reality of politics in contemporary democratic Uruguay is that of pressing for incremental and routine social reform inside a ‘Broad Front’ where ideological definitions for the future have become hazy. This paper explores the various ways that young Uruguayan Leftists work to reconcile these different senses of time and how these mediate their relationships with ‘significant generational others’. In so doing, I place the concept of time, of the perceived and socially constructed sense of acting in the current of a particular historical time, at the center of analysis.     

A Test of the Emergent Norm Theory of Collective Behavior

Objective: The paper uses the timing of evacuation behavior of occupants of the World Trade Center at the time of the explosion of February 26, 1993, to test predictions from Emergent Norm Theory. Method: It uses ordinary least square multiple regression analysis to examine data from a survey done in the first week in May 1993 of 415 people who worked at the World Trade Center. Results: The theory's predictions regarding the additive effects of size of group and preexisting social relationships on the timing of evacuation are supported. However, the findings document important and unexpected interaction effects of these two variables on the effects of perceived threat, resources, and cooperativeness on the timing of evacuation. Conclusion: The results augment the theory by showing the continued importance of enduring social relationships as determinants of collective behavior. Enduring social relationships are not only useful to differentiate collective behavior from institutionalized behavior but also specify the dynamics attending the occurrence of collective behavior.     

Incorporating self‐determination into substance abuse prevention programming for youth transitioning from foster care to adulthood

Youth transitioning from foster care to adulthood are at higher risk for alcohol and substance abuse disorders than general population youth. At the same time, these youths are often recipients of strong clinical intervention, often at levels considered unnecessary, for other mental health or behavioural challenges. Because of this, there is sometimes resistance from providers to offer services such as substance abuse prevention programming as it may be seen as contributing to youths' overclinicalization, stigmatization, or retraumatization. Using thematic content analysis, this qualitative study analysed focus groups with community stakeholders providing recommendations on support services for youth transitioning from foster care to adulthood to derive strategies for delivering substance abuse prevention programming in a way that enhances youth self‐determination. Findings were organized by self‐determination theory's 3 key psychological needs: autonomy, competence, and relatedness. All three needs were represented in stakeholder recommendations, which were translated into strategies for bolstering youths' achievement of each need. Strategies include a mix of those already present in motivational interviewing‐based brief substance abuse prevention interventions as well as more unique strategies that are much less frequently employed but that may better meet the needs of youth with foster care experience.     

Applying a Community Violence Framework to Understand the Impact of Immigration Enforcement Threat on Latino Children

Heeding the call put out by the New England Journal of Medicine (2017), we utilize an ecological–transactional model as a conceptual framework for understanding existing literature and for guiding future research on immigration enforcement threat and Latino child development. Using the World Health Organization's definition of violence, we draw on literature from psychology, medicine, social work, and developmental psychology to outline how the anti-immigrant climate in the United States and the threat of immigration enforcement practices in everyday spaces are experienced by some Latino children as psychological violence. Researchers, teachers, and practitioners are encouraged to be aware of how uncertainty and threat regarding familial safety adversely impacts the lives of Latino children in immigrant households, especially in charged, anti-immigrant climates.
