Preventing Substance Abuse Among American-Indian Adolescents: A Bicultural Competence Skills Approach

Tobacco, alcohol, and drug use are problems for American-Indian people. We reviewed these problems and the explanations for them and described a bicultural competence skills approach for preventing substance abuse with American-Indian adolescents. Data from a study of that approach suggest its efficacy with American-Indian youth. At posttest and a 6-month follow-up, American-Indian subjects who received preventive intervention based on bicultural competence skills concepts improved more than did American-Indian subjects in a no-intervention control condition on measures of substance-use knowledge, attitudes, and interactive skills, and on self-reported rates of tobacco, alcohol, and drug use. Our findings have implications for future substance-abuse prevention research with American-Indian people.     

Clauses and the semantic representation of words

When a sentence with more than one clause is processed, words of the first clause become less available for recall or recognition once the clause boundary has been passed. One common interpretation of this observation is that the representation of a given word shifts from a predominantly surface form (e.g., phonological or lexical) to a semantic form, after the clause boundary. Two experiments that test that interpretation are reported. In the first experiment, two-clause spoken sentences were followed by spoken word or picture probes. Pictures were intended to provide a fast semantic match to probed words, but a slow surface match. Although response times exhibited a robust main effect of the clause position of the probe, no interaction with probe type was found. Similar results were obtained in a second experiment that compared pictures with written word probes. The faster response to picture than to word probes in the second experiment indicates that subjects did not covertly name the picture, but made a semantic match (as intended). These observations suggest the following reinterpretation of earlier sentence memory experiments: Words in the most recent clause of a sentence are more available than words in an earlier clause because their semantic representations are more active, not because their surface representations are more active.     

Sustainable mobility choices: Exploring the impact of consumers' values,attitudes, perceived behavioural control and subjective norms on the likelihood to choose sustainable mobility options

This study explores consumers' behaviour regarding sustainable mobility options. A mixed-methods approach was adopted to examine the impact of bio-altruistic values, egoistic values, environmental attitudes, attitudes regarding sustainable mobility, perceived behavioural control and subjective norms on the likelihood of choosing sustainable mobility options. To collect the data, an online survey was applied to a sample of 645 Portuguese consumers, which included one single non-mandatory open-ended question to understand which factors could contribute to increase respondents' likelihood to choose more sustainable transport modes. As most studies in the mobility field are quantitative, combining both quantitative and qualitative data provided a greater in-depth analysis with richer findings. Firstly, findings revealed that attitudes towards sustainable mobility, subjective norms, perceived behaviour control, and egoistic values influence the likelihood of choosing sustainable mobility options. However, environmental attitudes, altruistic and biospheric values do not impact this choice. Secondly, consumers highlight that the existence of a broad public transport network, safe bicycle lanes, and accessible prices would contribute to their likelihood of adopting more sustainable mobility behaviours. The content analysis of 402 answers allowed to discover new dimensions that influence sustainable mobility behaviour, such as safety, respect towards bicycle users, mindset adjustment, willpower, and especially physical efforts associated with long distances, bad weather, orography, and the difficulty to transport materials or other people. Based on both quantitative and qualitative findings, the paper provides key recommendations for politicians, urban planners, and transport organisations, that according to respondents, would contribute to increase their use of sustainable mobility.     

Category discrimination by pigeons using five polymorphous features

Eight pigeons were trained to discriminate between sets of color photographs of natural scenes. The scenes differed along five two-valued dimensions (site, weather, camera distance, camera orientation, and camera height), and all combinations of the feature values were used. One value of each dimension was designated as positive, and slides containing three or more positive feature values were members of the positive stimulus set. Thus, each feature had an equal, low, correlation with reinforcement, and all features had zero correlations with each other. Seven of the 8 pigeons learned this discrimination, and their responding came under the control of all five features. Within the positive and negative stimulus sets, response rates were higher to stimuli that contained more positive feature values. Once discrimination had been achieved, reversal training was given using a subset of the slides. In this subset, only a single feature was correlated with reinforcement. All pigeons learned this reversal successfully and generalized it to additional photographs with the same feature content. After reversal, the original reinforcement contingencies were reinstated, and training was continued using all the slides except those that had been used in reversal. Reversal generalized to these slides to some extent. Analysis of the response rates to individual slides showed that, compared with prereversal training, only the feature that had been subjected to reversal contingencies showed a reversed correlation with response rate. The remaining features showed the same correlation with response rate as they had before reversal training. Thus, reversal on some members of a category following category discrimination training led to generalization to stimuli within the category that were not involved in the reversal, but not to features that were not reversed. It is therefore inappropriate to refer to the pigeons as learning a concept.     

"Having it all": women's perception of impact of female promotion on threat of domestic violence

This study involved 219 women participants. The main aim of the present study is to examine the perceived consequences of a work-related promotion for the female partner in a heterosexual relationship. The impact of the promotion was manipulated - both partners share paid and domestic work, the male partner taking responsibility for all the domestic work - or female partner continuing to do all the domestic work, as well as the male partner's sexist ideology. Finally, the study examined gender ideology of participants. The results showed that participants felt that violence was more likely when the male partner was presented as sexist and that this was due to a perception of threat on the part of the male partner.     

Don't leave me: the effect of dependency and emotions in relationship conflict

Two studies examined how the effect of dependency and emotions on the dynamics of relationship conflict differs between men and women. In Study 1, 96 women and 67 men were presented with conflict situations that might occur in their relationship; the probability of aggression, anger, and dependency was measured. Results showed that anger mediated the relationship between dependency and the intention to use aggression, in men, but not in women. In Study 2, 95 women and 65 men wrote about a conflict situation that they had experienced with their partner; loyalty, guilt, and dependency were measured. Results showed that dependency predicted loyalty among women, and that this effect was mediated by guilt.     

Perception of Candomble Practitioners About Herbal Medicine and Health Promotion in Ceará, Brazil

Candomble, a Brazilian religion of African origin that worships Orishas, promotes “healing” assistance during its worship rituals using therapy with plants and beliefs. From its ancestry tradition, the respect and beware with nature are expressed. Therefore, the aim of this study is to investigate the perception of ethnoecology and health promotion among Candomble practitioners from a Candomble temple in the state of Ceará, Brazil. The ethnography was designed to allow greater immersion into the current mystique. This immersion results in the breaking of existing prejudices and admiration for their worldview. Thus, it can be observed that people seek Candomble to get rid of “bad” health difficulties, such as insomnia, depression, eyesight problems among others, which are commonly treated with herbal preparations, baths, and teas, using plants native to the region; however, their indications are not always in accordance with scientific evidence. In parallel with biomedicine, their hospitable and healthcare practices are considered by most as the equivalent to traditional healthcare actions, but greater recognition of biomedicine is necessary. Based on this perspective, the use of native plants in Candomble is examples of memory, hospitality, and humanization for the community wellness.
