Comercialización social de la donación de órganos en Colombia: un estudio exploratorio

Resumen Este estudio tiene como objetivo determinar las actitudes, creencias y aspectos culturales que motivan a los familiares de las personas fallecidas a donar sus órganos, a través de los cuales el marketing social puede desarrollar acciones que promuevan cambios de comportamiento. Se realizó un estudio de investigación descriptivo exploratorio a través del método de recopilación de información cualitativa con entrevistas en profundidad utilizando un cuestionario semiestructurado, procesado por el software NVivo 11. Descubrimos que las razones por las cuales los miembros de la familia donaron órganos fueron principalmente manifestaciones durante la vida del donante, el deseo de las familias de poder ayudar a otras personas (altruismo) y creencias religiosas.

A meta-analysis of the effect of visiting zoos and aquariums on visitors' conservation knowledge, beliefs, and behavior

Zoos and aquariums are well placed to connect visitors with the issues facing biodiversity globally and many deliver interventions that seek to influence visitors' beliefs and behaviors with respect to conservation. However, despite primary studies evaluating the effect of such interventions, the overall effect of engaging with zoos and the factors that influence this effect remain unclear. We conducted a systematic review to investigate the effect of zoo-led interventions on knowledge, beliefs (attitudes, intentions, self-efficacy, and social norms), and behavior among zoo visitors. These outcomes were identified using the Theory of Planned Behavior as a theoretical lens. We identified and described the nature of zoo-led interventions in 56 studies and used the behavior change technique (BCT) taxonomy to identify 6 specific BCTs used in interventions to date. Multilevel meta-analyses revealed a small to medium positive effect of engaging with zoo-led interventions on outcomes (d+ = 0.40, 95% confidence interval = 0.28-0.51). Specifically, visitors were more knowledgeable about conservation issues, held more favorable attitudes toward conservation, and reported being more likely to act for the benefit of biodiversity. No evidence of publication bias was present. Effect sizes were, however, heterogeneous and subgroup analyses revealed that the nature of the intervention or type of outcome did not explain this variance. Larger effects were, however, found in studies conducted at a single institution relative to research at multiple institutions and studies that used within-participant designs relative to between-participant designs. Taken together, these findings demonstrate how behavior change frameworks can be used to describe zoo-led interventions and supports the assertion that zoos and aquariums can promote changes in beliefs and behaviors that may help protect biodiversity.

[Preliminary Study on Cognitive Determinants Influencing Argentine Youngsters towards Intensive Alcohol Consumption or Binge Drinking]

INTRODUCTION

The current alcohol consumption pattern among youngsters and adolescents, characterized by heavy drinking during a few hours, several days a week, or binge drinking (binge drinking, concentrated drinking or long-gulp drinking) is a reality in many countries, including Spain and Argentina.

OBJECTIVE

To describe cognitive determinants in the behavior regarding excessive alcohol consumption (binge drinking) in 16-25 year subjects in Argentina.

METHODOLOGY

An ad hoc survey was conducted to assess cognitive determinants influencing heavy alcohol consumption, according to I. Ajzen's guidelines.

RESULTS

There are significant statistic differences between the group of heavy drinkers and the group that does not reach such level of consumption in relation to behavioral beliefs, and control beliefs. Both groups recognized consumption is noxious and not safe; no differences were observed concerning normative beliefs.

CONCLUSIONS

There is a complex interaction mong attitudinal factors, motivational and behavior control factors. Instruments require greater sensitivity and further in-depth analysis is required regardomg short, middle and long consequences generated by binge drinking and its role as a positive or negative reinforment.
