Retraction Note: Globalization and vulnerable populations in times of a pandemic: A Mayan perspective

Understanding representations of disease in various art genres provides insights into how patients and health care providers view the diseases. It can also be used to enhance patient care and stimulate patient self-management. This paper reviews how cardiovascular diseases are represented in novels, films, and paintings: myocardial infarction, aneurysm, hypertension, stroke, heart transplantation, Marfan’s disease, congestive heart failure. Various search systems and definitions were used to help identify sources of representations of different cardiovascular diseases. The representations of the different diseases were considered separately. The Common Sense Model was used a theoretical model to outline illness perceptions and self-management in the various identified novels, films, and paintings. Myocardial infarction followed by stroke were the most frequently detailed diseases in all three art genres. This reflects their higher prevalence. Representations ranged from biomedical details through to social and psychological consequences of the diseases. Artistic representations of cardiovascular diseases reflect cognitions, emotions, and images of prevalent disease. These representations shape views and behaviour of ill and healthy persons regarding heart diseases. As these representations are amenable to change, they deserve further research, which may be instrumental in improving the quality of life of persons struck by cardiovascular diseases. Changing illness perceptions appears to be a method to improve self-management and thereby quality of life in patients with various cardiovascular diseases.     

Stereotypes and beliefs about different ethnic groups in Spain. A study with Spanish and Latin American children living in Madrid

96 Spanish and Latin American children from 3 grades in Madrid reported their knowledge of positive and negative stereotypes regarding Spaniards, Gypsies, Latin American and Chinese people. Their personal beliefs about these four ethnic groups were also assessed. Stereotypes about Spaniards were perceived as overwhelmingly positive and least negatively while stereotypes about Gypsies were rarely positive and often negative. Spanish children attributed more positive and fewer negative stereotypes to Chinese immigrants than Latin American children did. Older children reported more positive stereotypes about Gypsies than younger children and older Spanish children reported fewer positive stereotypes for their own group than their younger counterparts. Older children's personal beliefs about Gypsies were less consistent with negative stereotypes than younger children's. Older children also showed greater discrepancy of their personal beliefs with positive stereotypes of Spaniards than younger children did. Findings are discussed within the context of socio-cognitive approaches.     

Diffusion of novel foraging behaviour in Amazon parrots through social learning

While social learning has been demonstrated in species across many taxa, the role it plays in everyday foraging decisions is not well understood. Investigating social learning during foraging could shed light on the emergence of cultural variation in different groups. We used an open diffusion experiment to examine the spread of a novel foraging technique in captive Amazon parrots. Three groups were tested using a two-action foraging box, including experimental groups exposed to demonstrators using different techniques and control birds. We also examined the influence of agonistic and pilfering behaviour on task acquisition. We found evidence of social learning: more experimental birds than control birds interacted with and opened the box. The birds were, however, no more likely to use the demonstrated technique than the non-demonstrated one, making local or stimulus enhancement the most likely mechanism. Exhibiting aggression was positively correlated with box opening, whilst receiving aggression did not reduce motivation to engage with the box, indicating that willingness to defend access to the box was important in task acquisition. Pilfering food and success in opening the box were also positively correlated; however, having food pilfered did not affect victims’ motivation to interact with the box. In a group context, pilfering may promote learning of new foraging opportunities. Although previous studies have demonstrated that psittacines are capable of imitation, in this naturalistic set-up there was no evidence that parrots copied the demonstrated opening technique. Foraging behaviour in wild populations of Amazons could therefore be facilitated by low-fidelity social learning mechanisms.     

Student Explanations in the Context of Computational Science and Engineering Education

Creating explanations is an important process for students, not only to make connections between novel information and background knowledge, but also to be able to communicate their understanding of any given topic. This article explores students’ explanations in the context of computational science and engineering, an important interdisciplinary field that enables scientists and engineers to solve complex problems. Specifically, this study explores: (a) students’ approaches to create written explanations of programing code and (b) the relationship between students’ explanations and their ability to do computer programing. Students wrote in-code comments for 3 MATLAB^® worked-examples, which were qualitatively analyzed using a coding scheme. Different approaches to self-explain were identified using hierarchical cluster analysis, and differences in students’ ability to do computer programing were identified using analysis of variance. The resulting approaches to self-explain were: original solution, mechanistic, principle-based, limited, and goal-based. The findings suggest that experienced students wrote simple in-code comments to self-explain, but students with lower ability to do computer programing wrote more comprehensive explanations, as they may take this as a learning opportunity.     

The development of the conception of socioeconomic mobility in children from Mexico and Spain

The authors studied the developmental stages of children's understanding of upward socioeconomic mobility. They interviewed one hundred 6- to 14-year-old participants from Mexico and Spain and asked them about sources of wealth and factors related to socioeconomic mobility. Categorical analyses of the responses showed few age-related changes but noted some cross-national differences. A different analysis designed to identify levels of understanding showed a significant association between age and type of explanation of socioeconomic mobility. Overall, cross-national comparisons yielded similarities in children's developmental trends, and only slight differences were found with regard to cultural background. The present results contrast with those of studies conducted from the perspective of the social representation theory.     

Retrieval-induced forgetting in perceptually driven memory tests

Recent data (T. J. Perfect, C. J. A. Moulin, M. A. Conway, & E. Perry, 2002) have suggested that retrieval-induced forgetting (RIF) depends on conceptual memory because the effect is not found in perceptually driven tasks. In 3 experiments, the authors aimed to show that the presence of RIF depends on whether the procedure induces appropriate transfer between representations and competition rather than on the nature of the final test. The authors adapted the standard paradigm to introduce lexical categories (words that shared the first 2 letters) at study and practice. Direct and indirect fragment completion tests were used at retrieval. The results showed significant RIF effects in perceptually driven tasks. Furthermore, they indicated that the presence of RIF effects depended on using adequate cuing to induce competition during the retrieval practice and on the final memory test tapping the inhibited representation.     

The use of moral dilemmas for teaching agricultural engineers

Agricultural engineers’ jobs are especially related to sustainability and earth life issues. They usually work with plants or animals, and the aim of their work is often linked to producing food to allow people to improve their quality of life. Taking into account this dual function, the moral requirements of their day-to-day professional practice are arguably greater than those of other professions. Agricultural engineers can develop their ability to live up to this professional responsibility by receiving ethical training during their university studies, not only by taking courses specifically devoted to ethics, but also by having to deal with moral questions that are integrated into their technical courses through a program of Ethics Across the Curriculum (EAC). The authors feel that a suitable pedagogical technique for achieving this goal is the use of moral dilemmas, following Kohlberg’s theory of levels of morality (1981), with the final objective of attaining a post-conventional level. This paper examines the possibilities and limitations of using moral dilemmas as a pedagogical technique for training agricultural engineers. The cases, discussions, and evaluation used in the Agricultural Engineering Department of the Technical University of Valencia (Spain) are also presented. An earlier version of this paper was presented at the 2005 conference, Ethics and Social Responsibility in Engineering and Technology, Linking Workplace Ethics and Education, co-hosted by Gonzaga University and Loyola Marymount University, Los Angeles, CA, USA, 9–10 June 2005.     

The Bridge of Benevolence: Hutcheson and Mencius

The Scottish sentimentalist Francis Hutcheson and the Chinese Confucianist Mencius give benevolence (ren) a key place in their respective moral theories, as the first and foundational virtue. Leaving aside differences in style and method, my purpose in this essay is to underline this similarity by focusing on four common features: first, benevolence springs from compassion, an innate and universal feeling shared by all human beings; second, its objects are not only human beings but also animals; third, it is sensitive to proximity; and finally, it has to be constantly cultivated in order to become a character trait. I will conclude with some brief remarks as to how this understanding of benevolence as rooted in feeling rather than reason, and in personal rather than impersonal relationships, helps to illuminate part of the discussion in moral philosophy today.
