Indigenous aid workers carry out the majority of humanitarian aid work, yet there is little empirical information available on their support needs in different contexts. Focus groups (N = 26: Study 1) and a survey (N = 137; Study 2) were conducted with Guatemalan aid workers to explore their exposure to violence, posttraumatic stress symptoms, burnout, support needs, and motivators. Participants reported experiencing an average of 13 events of community violence and 17% reported symptoms consistent with posttraumatic stress disorder (PTSD). Direct community violence exposure and levels of emotional exhaustion were positively related to PTSD symptoms, while levels of personal accomplishment were inversely related to PTSD symptoms. Expressed support needs, motivators and rewards for aid work in the face of adversity are also reported as potential protective factors for further exploration. Implications for training and support of aid workers in similar contexts are also suggested.  相似文献

There is mounting evidence that physical aggression and nonaggressive, rule‐breaking delinquency constitute two separable though correlated subtypes of antisocial behavior. Even so, it remains unclear whether these behavioral subtypes have meaningfully different interpersonal correlates, particularly as they are subsumed within the same broad domain of antisocial behavior. To evaluate this, we examined whether hostile perceptions of others (assessed via exposure to a series of neutral unknown faces) were linked to level and type of antisocial behavior aggression vs. rule‐breaking, and moreover, whether this association persisted even when also considering the common association with negative affect (as manipulated via written recollection of one's best and worst life experiences). Analyses revealed that aggression, but not rule‐breaking, was uniquely tied to hostile perceptions of others. Furthermore, this association persisted over and above the common association of both hostile perceptions and aggression with negative affect (at both trait and state levels). Such results provide additional support for clinically meaningful differences between the behavioral subtypes of aggression and nonaggressive rule‐breaking and for the independent role of hostile perceptions in aggressive behavior.

Delay discounting is the process by which a commodity loses value as the delay to its receipt increases. Rapid discounting predicts various maladaptive behaviors including tobacco use. Typically, delay discounting of different outcomes has been compared between cigarette smokers and nonsmokers. To better understand the relationship of delay discounting to different modes of tobacco use, we examined the differences in delay discounting of different outcomes between cigarette smokers, smokeless tobacco users, e-cigarette users, and non-tobacco users. In the present study, all participants completed 8 titrating delay-discounting tasks: $100 gain, $500 gain, $500 loss, alcohol, entertainment, food, a temporary health gain, and a temporary cure from a disease. Non-tobacco users discounted most outcomes less than tobacco users overall; however, there were no differences in discounting among the different types of tobacco users. These results suggest that nicotine consumption of any kind is associated with a higher degree of impulsivity compared to non-tobacco users. Adoption of tobacco products that have been perceived as less harmful (e.g., e-cigarettes) is not associated with a baseline difference or decrease in delay discounting if adopted after a history of cigarette use.  相似文献

The present study examined resurgence of reinforced variability in college students, who completed a 3-phase computer-based variability task. In the first phase, baseline, points were delivered for drawing rectangles that sufficiently differed from previous rectangles in terms of a target dimension (size or location, counterbalanced) but were sufficiently similar in terms of the alternative dimension. In the second phase, alternative, points were only delivered for rectangles that were sufficiently different in terms of the alternative dimension, but repetitive in terms of the target dimension. In the third phase, extinction, no points were delivered. In baseline, participants made rectangles that were highly varied in terms of the target dimension and less varied in terms of the alternative dimension, and vice versa in the alternative phase. During extinction, levels of variability increased for the target dimension, providing evidence for resurgence of reinforced variability of a specific dimension of behavior. However, levels of variability also remained high for the alternative dimension, indicating that extinction-induced response variability may also have impacted the results. Although future research is needed to explore other explanations, the results of this study replicate prior research with pigeons and provide some support for the notion of variability as an operant.  相似文献

All accounts of language acquisition agree that, by around age 4, children’s knowledge of grammatical constructions is abstract, rather than tied solely to individual lexical items. The aim of the present research was to investigate, focusing on the passive, whether children’s and adults’ performance is additionally semantically constrained, varying according to the distance between the semantics of the verb and those of the construction. In a forced-choice pointing study (Experiment 1), both 4- to 6-year olds (N = 60) and adults (N = 60) showed support for the prediction of this semantic construction prototype account of an interaction such that the observed disadvantage for passives as compared to actives (i.e., fewer correct points/longer reaction time) was greater for experiencer-theme verbs than for agent-patient and theme-experiencer verbs (e.g., Bob was seen/hit/frightened by Wendy). Similarly, in a production/priming study (Experiment 2), both 4- to 6-year olds (N = 60) and adults (N = 60) produced fewer passives for experiencer-theme verbs than for agent-patient/theme-experiencer verbs. We conclude that these findings are difficult to explain under accounts based on the notion of A(rgument) movement or of a monostratal, semantics-free, level of syntax, and instead necessitate some form of semantic construction prototype account.  相似文献

Human immunodeficiency virus (HIV) continues to be a prominent health and social justice issue, especially for African American communities in the Southern United States. Gender role norms, specifically within faith-based communities in the South, pose challenges to empowering women to make safer sexual health decisions. To explore perceptions of gender norms and sexual health, 42 qualitative interviews were gathered from female members of 16 predominantly African American churches in Atlanta, GA. Constructs from the theory of gender and power and the social ecological model were used to guide coding and analysis. Participants discussed their experiences with gender norms and gender-based power differentials at the institutional (i.e., church), familial, and interpersonal (i.e., intimate relationship) levels. Because of the attitudes and beliefs held by their religious communities and families, many participants recalled struggling to assert themselves in sexual relationships and recalled engaging in risky and unwanted sexual behavior, especially during their young adult years. However, as the participants matured, they worked to overturn traditional gender norms, empowering both their children and women in their religious communities to make healthy, autonomous sexual decisions. Moving forward, participants want their churches and members of their faith communities to play an active role in the empowerment of African American women and provide them with the confidence and education necessary to negotiate sexual decisions with their partners.
