This essay discusses engineering ethics in Puerto Rico by examining the impact of the Colegio de Ingenieros y Agrimensores de Puerto Rico (CIAPR) and by outlining the constellation of problems and issues identified in workshops and retreats held with Puerto Rican engineers. Three cases developed and discussed in these workshops will help outline movements in engineering ethics beyond the compliance perspective of the CIAPR. These include the Town Z case, Copper Mining in Puerto Rico, and a hypothetical case researched by UPRM students on laptop disposal. The last section outlines four future challenges in engineering ethics pertinent to the Puerto Rican situation. 相似文献

Despite the mental health needs in the military and improved access to military psychologists, many in need do not seek psychological services. The military policies, culture, and environment pose considerable barriers to help seeking. In turn, military practices often conflict with the psychologist’s professional ethics, leading to a range of ethical dilemmas including multiple relationships, multiple agencies, and limited confidentiality. To address ethical concerns and encourage service members to seek mental health services, this article proposes maintaining an understanding of military rules, law, and professional ethics; identifying multiple relationships and establishing boundaries up front; and collaborating with the patient in disclosures of information. 相似文献

The study explored whether intercultural competence was a significant predictor of religious attitudes among Third Culture Kids (TCKs), individuals who had spent their developmental years abroad. It also examined whether growing up as a missionary kid (MK) would predict religious attitudes. Two hundred and seventy-six TCKs from 37 countries and 19 religious affiliations completed the web-based survey that included measures of intercultural competence, religious attitudes and beliefs, and demographic information. Intercultural competence was a significant predictor of participants’ desire for all religions to be treated fairly whereas growing up as an MK was a significant predictor of participants’ desire for their religion to be unchallenged and of less desire for interreligious dialogue. The findings suggest that increasing intercultural competence may be a way to promote religious acceptance. 相似文献

Decision-making groups in organizations are often expected to function as a “think tank” and to perform “reality testing” to detect the best alternative. A biased search for information supporting the group's favored alternative impairs a group's ability to fulfill these requirements. In a two-factorial experiment with 201 employees and managers from various economic and public organizations, genuine and contrived dissent were investigated as counterstrategies to biased information seeking. Genuine dissent was manipulated by forming three-person groups whose members either all favored the same alternative individually (homogeneous groups) or consisted of a minority and a majority faction with regard to their favored alternative (heterogeneous groups). Contrived dissent was varied by the use or nonuse of the “devil's advocacy” technique. The results demonstrate that heterogeneity was more effective in preventing a confirmatory information-seeking bias than devil's advocacy was. Confidence was identified as an important mediator. Implications for the design of interventions aimed at facilitating reality testing in group decision making are discussed. 相似文献

Classroom discourse was examined as a predictor of changes in children's beliefs about their academic capabilities. Kindergarten, first-grade, and second-grade students (N = 106) participated in 2 waves of data collection, approximately 1 year apart. During the 1st year of the study, children's verbal interactions with their classmates were observed and recorded. Children rated their self-perceptions of academic competence during the 1st and 2nd years. Analyses revealed that changes over time in children's competence perceptions could be predicted from the types of statements that children made and had directed toward them by classmates. Examining sequences of child and classmate statements proved helpful in explaining the observed changes in children's perceptions of competence. 相似文献

Transient long-term potentiation (E-LTP) can be transformed into a long-lasting LTP (L-LTP) in the dentate gyrus (DG) by behavioral stimuli with high motivational content. Previous research from our group has identified several brain structures, such as the basolateral amygdala (BLA), the locus coeruleus (LC), the medial septum (MS) and transmitters as noradrenaline (NA) and acetylcholine (ACh) that are involved in these processes. Here we have investigated the functional interplay among brain structures and systems which result in the conversion of a E-LTP into a L-LTP (reinforcement) by stimulation of the BLA (BLA-R). We used topical application of specific drugs into DG, and other targets, while following the time course of LTP induced by stimulation of the perforant pathway (PP) to study their specific contribution to BLA-R. One injection cannula, a recording electrode in the DG and stimulating electrodes in the PP and the BLA were stereotactically implanted one week before electrophysiological experiments. Topical application of atropine or propranolol into the DG blocked BLA-R in both cases, but the effect of propranolol occurred earlier, suggesting a role of NA within the DG during an intermediate stage of LTP maintenance. The injection of lidocaine into the LC abolished BLA-R indicating that the LC is part of the functional neural reinforcing system. The effect on the LC is mediated by cholinergic afferents because application of atropine into the LC produced the same effect. Injection of lidocaine inactivating the MS also abolished BLA-R. This effect was mediated by noradrenergic afferents (probably from the LC) because the application of propranolol into the MS prevented BLA-R. These findings suggest a functional loop for BLA-R involving cholinergic afferents to the LC, a noradrenergic projection from the LC to the DG and the MS, and finally, the cholinergic projection from the MS to the DG. 相似文献

Research has consistently shown that aggressive video console and PC games elicit aggressive cognitions, affect, and behaviors. Despite the increasing popularity of racing (driving) games, nothing is known about the psychological impact of this genre. This study investigated whether playing racing games affects cognitions, affect, and behaviors that can promote risk taking in actual road traffic situations. In Study 1, the authors found that the frequency of playing racing games was positively associated with competitive driving, obtrusive driving, and car accidents; a negative association with cautious driving was observed. To determine cause and effect, in Study 2, the authors manipulated whether participants played 1 of 3 racing games or 1 of 3 neutral games. Participants who played a racing game subsequently reported a higher accessibility of cognitions and affect positively associated with risk taking than did participants who played a neutral game. Finally, on a more behavioral level, in Study 3, the authors found that men who played a racing game subsequently took higher risks in computer-simulated critical road traffic situations than did men who played a neutral game. Theoretical and practical implications are discussed. 相似文献
