Emotional reactions,coping and long‐term consequences of perceived discrimination among the Mapuche people of Chile

Although a substantial body of research has now documented the negative mental and physical health impacts of discrimination on various minority/non‐dominant groups, little has been reported on the impacts of such discrimination on indigenous populations. In this study, we investigated the self‐reported emotional reactions, coping responses and long‐term impacts of discriminatory experiences among 50 Mapuche adults in Chile. The limited literature suggests that a substantial proportion of the Chilean majority society is prejudiced and discriminatory towards the indigenous Mapuche population, and that the Mapuche experience discrimination. Interviews with participants indicated that discrimination was psychologically wounding, and aroused anger, undifferentiated bad feelings, shame and a sense of powerlessness. Participants responded with self‐protective, self‐controlled or confronting actions. Although negative long‐term effects were reported, ethnic re‐affirmation and strengthening of bonds within the Mapuche community were positive outcomes that seem to provide resilience for the participants. This does not discount however, the need for more research assessing the impacts of discrimination in Chile nor the need for anti‐discrimination measures to be implemented.

Prayer Behavior in Rural Kilimanjaro,Tanzania

Theories and empirical evidence regarding prayer behavior generally emerge from studies of survey respondents in developed countries. The research we describe here adds to the literature by exploring links between demographic characteristics and the frequency and content of prayers for respondents in rural Tanzania. We surveyed 349 Christian households from six villages in the country's Kilimanjaro region. In some aspects our findings match results from survey research conducted elsewhere, and in other aspects our results differ from those commonly reported in the literature. We suggest that local cultural and socioeconomic conditions may account for the differences in outcomes. These results suggest a need for caution in applying to poor countries theories and expectations drawn from the developed country context.

EFFECTS OF WITHIN-STIMULUS AND EXTRA-STIMULUS PROMPTING ON DISCRIMINATION LEARNING IN AUTISTIC CHILDREN1

Two different prompting procedures to teach visual and auditory discriminations to autistic children were compared. The first involved presenting an added cue as an extra-stimulus prompt. This required the child to respond to both prompt and training stimulus. The second involved the use of a within-stimulus prompt. This consisted of an exaggeration of the relevant component of the training stimulus and thus did not require that the child respond to multiple cues. The results indicated that (1) children usually failed to learn the discriminations without a prompt, (2) children always failed to learn when the extra-stimulus prompt was employed but usually did learn with the withinstimulus prompt, and (3) these findings were independent of which modality (auditory or visual) was required for the discrimination.     

Peak shift following simultaneous discriminations

Pigeons were exposed to stimuli presented on two keys. For some birds, the stimuli varied in a dimension of visual flicker-rate, and for others they varied in visual intensity. During differential training, concurrent schedules operated, with one stimulus correlated with one schedule and another stimulus correlated with a second schedule that arranged a lower, or zero, rate of reinforcement. The stimuli were alternated randomly on the two keys. Generalization tests were given in which the original two, and seven other stimuli lying in the same dimension, were presented in pairs on the two keys in various combinations. In the generalization test given after differential training, each bird showed peak shift. The data did not support explanation for peak shift that gave critical emphasis to whether stimuli were presented simultaneously or successively during differential training.     

Effects of signaling on temporal control of behavior in response‐initiated fixed intervals

Behavior and events distributed in time can serve as markers that signal delays to future events. The majority of timing research has focused on how behavior changes as the time to some event, usually food availability, decreases. The primary objective of the two experiments presented here was to assess how behavior changes as time passes between two time markers when the first time marker was manipulated but the second, food delivery, was held constant. Pigeons were exposed to fixed‐interval, response‐initiated fixed‐interval, and signaled response‐initiated fixed‐interval 15‐ and 30‐s schedules of reinforcement. In Experiment 1, first‐response latencies were systematically shorter in the signaled response‐initiated schedules than response‐initiated schedules, suggesting that the first response was a more effective time marker when it was signaled. In Experiment 2, responding in no‐food (i.e. “peak”) trials indicated that timing accuracy was equivalent in the three schedule types. Compared to fixed interval schedules, timing precision was reduced in the signaled response‐initiated schedules and was lowest in response‐initiated schedules. Results from Experiments 1 and 2 coupled with previous research suggest that the overall “informativeness” of a time marker relative to other events and behaviors in the environment may determine its efficacy.     

Associations of ethnic discrimination with symptoms of anxiety and depression among Hispanic emerging adults: a moderated mediation model

Background and Objectives: Emerging adulthood is often marked with elevated symptoms of anxiety and depression. Hispanic emerging adults may face cultural stressors such as ethnic discrimination that further increase levels of anxiety and depression symptoms. The study aims were to examine if (a) self-esteem mediated effects of ethnic discrimination on symptoms of anxiety and depression, and (b) if gender moderated the indirect effects of discrimination. Design: The study design was cross-sectional self-report. Method: Two moderated mediation models were tested, with 1084 Hispanic emerging adults (ages 18–25) enrolled in institutions of post-secondary in the United States. Results: Results indicated that (a) higher ethnic discrimination was associated with higher anxiety symptoms (β?=?.05, p?=?.04), higher depression symptoms (β?=?.06, p?=?.02), and lower self-esteem (β?=??.30, p?Conclusions: Findings suggest that the mediating effects of self-esteem linking ethnic discrimination with symptoms of anxiety and depression vary between genders.     

Hijab in the American workplace: visibility and discrimination

While the initial purpose of this article was to outline online collective action (OCA) towards promoting the rights of hijab-wearing Muslim women in the workplace, it became apparent that there were substantial impediments to this solidarity. Thus, the bulk of it takes up these obstacles, arguing that American hijabis face structural discrimination and Muslims in the United States are subjected to heightened discrimination when they are highly visible to the mainstream culture. This article reviews two cases of workplace discrimination against hijabis and the reactions to these incidents on the Huffington Post, Los Angeles Times, and hijab-oriented blogs. Findings indicate that intolerance of Muslims is prevalent across various political affiliations and apprehension associated with hijabi rights could be related to the perceived decline of white privilege. The analysis also demonstrates that there may be impediments to solidarity with hijabi rights within Muslim communities due to disagreements on the Qur’anic mandate of modesty, divergent perspectives on how Muslims can best promote their rights and ensure their safety, and misunderstandings related to the rights guaranteed under reasonable accommodation. Despite the various obstacles to solidarity with hijabis, the article traces various forms of OCA at local, national and international levels that were encountered on social media platforms.     

Bioethicists Can and Should Contribute to Addressing Racism

The problems of racism and racially motivated violence in predominantly African American communities in the United States are complex, multifactorial, and historically rooted. While these problems are also deeply morally troubling, bioethicists have not contributed substantially to addressing them. Concern for justice has been one of the core commitments of bioethics. For this and other reasons, bioethicists should contribute to addressing these problems. We consider how bioethicists can offer meaningful contributions to the public discourse, research, teaching, training, policy development, and academic scholarship in response to the alarming and persistent patterns of racism and implicit biases associated with it. To make any useful contribution, bioethicists will require preparation and should expect to play a significant role through collaborative action with others.
