This article explores significant factors influencing the process of Arab American racial formation. I bring into conversation theories of racial formation and ‘political shock’ in social movement scholarship to develop the notion of ‘racialized political shock’ as an important factor in how racial and ethnic groups mobilize and organize. Many moments of political shock are highly racialized and have the potential to reorder the racial and ethnic landscape in ways that can open opportunities or introduce constraints to mobilizations around racial formation. Drawing on existing studies of Arab Americans, this paper highlights how Arab American racial formation has been galvanized during moments of racialized political shock. In the Arab American case, these moments have led to a call for recognition outside the category of white. I conclude by outlining ways forward in the study of Arab Americans, who have been overlooked in studies of race and ethnicity in the US. 相似文献

This article explores Arab American "invisibility" as a central theme in the historical narrative of Arab immigrants and their descendants in North America. "Invisibility" is primarily addressed in terms of Arab Americans' paradoxical positioning within the US racial/ethnic classification system. The article argues that four central paradoxes shape Arab American identity. The first paradox is that Arab Americans are a complex, diverse community, but are represented as a monolith in popular North American media images. The second paradox is that Arab Americans are simultaneously racialized as whites and as non-whites. The third paradox is that Arab Americans are racialized according to religion (Islam) rather than biology (phenotype). The fourth paradox involves the intersection between religious forms of identity that Arab immigrants bring to the US and racial forms of identity that structure US society. Overall, the article claims that each paradox of Arab American identity reinforces the difficulties associated in classifying this population. 相似文献

Plants often lose natural enemies (herbivores and pathogens) while invading new geographic regions, as predicted by the Enemy Release Hypothesis. However, a similar reduction in attack might occur at a more local scale within an invader’s range as plants in marginal areas escape enemies that fail to find them or cannot maintain local populations. In this study, we test the hypothesis that isolated populations near the northern edge of an invader’s range escape the enemies present in more southern populations, using the non-native monocarpic biennial, common burdock (Arctium minus), as a model species. In southern Ontario, this plant is attacked by a wide range of insect herbivores, including generalist leaf chewers as well as leaf-mining flies (Liriomyza arctii, Calycomyza flavinotum) and an abundant lepidopteran seed predator (Metzneria lappella). Surveys over an 815 km transect from temperate southern to boreal northern Ontario indicate that damage by all of these enemies declines sharply with latitude, while plants in more northern areas are slightly larger and more fecund. Critically, seed parasitism drops from more than 85 % in the south to less than 25 % in the north. These results indicate that populations of Arctium near this species’ northern limit escape many of their usual natural enemies, potentially counteracting less favourable environmental conditions. Such escape from enemies near invaders’ range margins may accelerate further spread, including expected migration in response to climate change. 相似文献

As the minority group frequently at the centre of public fear in the post-9/11 era, Arab Americans’ own sentiment toward, and concerns with, crime, has eluded scholarly attention. This study investigated their fear of crime net of five empirically validated fear of crime theoretical models. Face-to-face interviews with a random sample of Arab and non-Arab households in Metro-Detroit, Michigan indicated that net of all controls, Arab Americans experienced significantly higher levels of fear concerning both general and bias crimes than non-Arab Americans. The greater fear among Arab Americans calls for policy and practice change, and moving from perceiving Arab Americans as a major “source” of fear, to “carriers” of fear who are in need of more attention, care, and assistance. 相似文献

Social jetlag, the misalignment between the internal clock and the socially required timing of activities, is highly prevalent, especially in people with an evening chronotype and is hypothesized to be related to the link between the evening chronotype and major depressive disorder. Although social jetlag has been linked to depressive symptoms in non-clinical samples, it has never been studied in patients with major depressive disorder (MDD). This study is aimed to study social jetlag in patients with major depressive disorder and healthy controls, and to further examine the link between social jetlag and depressive symptomatology. Patients with a diagnosis of MDD (n = 1084) and healthy controls (n = 385), assessed in a clinical interview, were selected from the Netherlands Study of Depression and Anxiety. Social jetlag was derived from the Munich Chronotype Questionnaire, by calculating the absolute difference between the midsleep on free days and midsleep on work days. Depression severity was measured with the Inventory of Depressive Symptomatology. It was found that patients with MDD did not show more social jetlag compared to healthy controls, neither in a model without medication use (β = 0.06, 95% CI: ?0.03–0.15, p = 0.17) nor in a model where medication use is accounted for. There was no direct association between the amount of social jetlag and depressive symptoms, neither in the full sample, nor in the patient group or the healthy control group. This first study on social jetlag in a clinical sample showed no differences in social jetlag between patients with MDD and healthy controls. 相似文献

Arms races between brood parasites and their hosts provide model systems for studying the evolutionary repercussions of species interactions. However, how naive hosts identify brood parasites as enemies remains poorly understood, despite its ecological and evolutionary significance. Here, we investigate whether young, cuckoo-naive superb fairy-wrens, Malurus cyaneus, can learn to recognize cuckoos as a threat through social transmission of information. Naive individuals were initially unresponsive to a cuckoo specimen, but after observing conspecifics mob a cuckoo, they made more whining and mobbing alarm calls, and spent more time physically mobbing the cuckoo. This is the first direct evidence that naive hosts can learn to identify brood parasites as enemies via social learning. 相似文献

Using data from the Early Childhood Longitudinal Study–Kindergarten Cohort (N = 13,970), we examined whether two aspects of school-family connections, parental involvement and communication quality, accounted for the association between classroom composition and children's academic and socioemotional functioning following the transition to elementary school. For students with more same-race/ethnic representation in their classrooms, greater classroom race/ethnic diversity promoted more parental involvement, which in turn promoted children's interpersonal skills and reading achievement. Classroom diversity made little difference to parental involvement when students had fewer same-race/ethnic peers in the classroom. Teacher–parent communication quality did not emerge as an explanatory mechanism, and findings did not vary by the race/ethnic match between students and their teachers. 相似文献

Winter pruning is a cultural practice used to modify vegetative growth, which is likely to affect the development of pests. However, it has been poorly defined as a cultural method for diminishing the population levels of the pomegranate aphid Aphis punicae (Hemiptera, Aphididae) in pomegranate orchards. This study aimed to evaluate the impact of winter pruning of pomegranate on A. punicae population and their natural enemies. The results showed that winter pruning significantly decreased the population of A. punicae (p < 0.05) in pomegranate. Also, number of natural enemies decreased in pomegranate trees after winter pruning. This technical practice affects the number of winged and wingless individuals, the mean relative growth rate, the specific age of the population and the infestation rate. Winter pruning for A. punicae control in pomegranate orchards is highly recommended. 相似文献

Non-timber forest products contribute significantly to rural livelihoods in the West African savannas. This study investigates differences in use preferences for native woody species in six categories of plant use and their economic returns among five ethnic groups in Northern Benin. Ethnobotanical survey data from 230 households revealed that both ethnic affiliation and location significantly impact species’ valuation. Of a total of 90 species, 61 % were used for medicinal applications, 41 % as firewood, 39 % for construction, and 32 % as human foods. While certain plant species were used by all rural dwellers, others were used exclusively by particular ethnic groups. Vitellaria paradoxa, Parkia biglobosa and Adansonia digitata are key economic species for all groups. Conservation measures should consider multi-purpose trees fulfilling subsistence and cash needs while taking into consideration cultural differences in use preferences. 相似文献

This article examines the role co-ethnic youth basketball leagues play in shaping ethnic community among third- and fourth-generation Japanese American youth. With dwindling rates of Japanese immigration, increased rates of out-marriage, and fewer cultural hubs available, finding a thriving ethnic community has become a particular challenge for later-generation Japanese Americans. Drawing from ethnographic data, I argue that even among highly ‘assimilated’ Japanese Americans, youth basketball leagues serve as an active space for constructing and preserving ethnic community and social networks. I demonstrate how through social, cultural, and spatial interactions facilitated by sports, some Japanese Americans have found a sense of ethnic ‘connectedness’ within basketball leagues while performing their own renditions of ethnic identity that is simultaneously attentive to fluid local and global connections. These findings illuminate the role and importance of sport through which Japanese Americans challenges the racial contours of American-ness and belonging while claiming their place, locally, nationally, and transnationally. 相似文献

This study investigated U.S. ethnic majority and minority youth's perceptions of fair and unfair treatment by authorities and evaluations of three situations of interracial exclusion (N = 685). Findings revealed that older adolescents who reported fair treatment by authorities were more likely to perceive wrongfulness in interracial exclusion scenarios than were their peers who reported unfair treatment. Additionally, in explaining the wrongfulness of interracial exclusion, older adolescents who had not experienced unfair treatment by authorities were more likely to mention racial prejudice than were their counterparts who had experienced unfair treatment. Results are discussed with reference to developmental theory on authority relations and the positive benefits of authority-adolescent relationships that reflect just and fair treatment. 相似文献

Ethnicity looks something like kinship on a larger scale. The same math can be used to measure genetic similarity within ethnic/racial groups and relatedness within families. For example, members of the same continental race are about as related (r = 0.18–0.26) as half-siblings (r = 0.25). However (contrary to some claims) the theory of kin selection does not apply straightforwardly to ethnicity, because inclusive fitness calculations based on Hamilton's rule break down when there are complicated social interactions within groups, and/or groups are large and long-lasting. A more promising approach is a theory of ethnic group selection, a special case of cultural group selection. An elementary model shows that the genetic assimilation of a socially enforced cultural regime can promote group solidarity and lead to the regulation of recruitment to groups, and to altruism between groups, based on genetic similarity – in short, to ethnic nepotism. Several lines of evidence, from historical population genetics and political psychology, are relevant here. 相似文献

Children's evaluations of two parental roles, working outside the home, and staying home to take care of children, were assessed in second (M = 7.13 years, SD = .39) and fifth grade (M = 10.42, SD = .57) students (N = 121). Children viewed it as acceptable for both mothers and fathers to work full-time, and used personal choice and social conventional reasons as justifications. In contrast, children found it less acceptable for fathers to stay at home than for mothers to stay at home, and they used gender stereotypes about domestic roles as justifications. With age, children were more flexible in their reasoning and used fewer stereotypes in their evaluations; children from traditional family structures used more stereotypic expectations than did children from non-traditional ones. Overall, children's interpretations of competence in a caretaker role was highly contingent on the gender of the parent. 相似文献

The present study investigated social jetlag in school students of the Raipur district of Chhattisgarh. The sample consisted of 919 school students from six different schools, age range 12–19 year, comprising of both males (n = 513) and females (n = 406). Two inventories, the 19-item MEQ and MCTQ (Munich Chronotype Questionnaire) were employed. Data analysis (SPSS) used t-test, Chi-square test, ANOVA, and correlation. The results revealed that 73.9% of the sample had social jetlag. There were significant effects upon social jetlag of chronotype, gender, and the use of an alarm clock. Owls were at a higher risk of having social jetlag. There was a significant positive correlation between the amount of social jetlag and the time spent watching television. From these results, it is concluded that there is prevalence of social jetlag, particularly among boys and those who use an alarm clock. The results also lead to the prediction that those school students with social jetlag will be predisposed to health hazards associated with it in the future. Thus it is recommended that school students must be provided with sleep education so that they understand the role of sleep on health and do not become sleep deprived. 相似文献

This paper argues that the refusal of the Muslim Council of Britain to attend Holocaust Memorial Day highlights a key dimension of memory as political myth: namely, the sense that time is cyclical. Prior external and internal enemies (in their current manifestations) are apocalyptically destined to threaten the integrity of the nation once more. Hence, ideologies based on political myths draw on both the future hopes and the future fears of people. The paper highlights the similarities between Jewish and Pakistani fears, rooted in the Holocaust and Partition, of a repeated ‘cycle of death and suffering’. These loom large especially for those suffering racism. The more bound people are by their narrow group's particular symbols and history, the more apocalyptic their vision of this future is likely to be. 相似文献

Happiness and Social Exclusion of Indigenous Peoples in Taiwan - A Social Sustainability Perspective
Jiun-Hao Wang 《PloS one》2015,10(2)
IntroductionHappiness and social inclusion are important indicators of social sustainability, as recommended in the Sustainable Development Goals; however, little is known about the social sustainable development of ethnic minorities. To fill this knowledge gap, special attention is paid to understanding the issues of social exclusion and happiness in relation to the indigenous peoples in Taiwan.MethodsData used were drawn from a nationwide representativeness survey of the Taiwanese Indigenous People in 2007; it included 2,200 respondents. This study employed binary logistic regression to examine the effects of different domains of social exclusion on the likelihood of perceiving happiness; other exogenous factors, were controlled.ResultsThe results show that among the respondents, mountain indigenous peoples, females, the elderly and those who are healthier, wealthier, highly educated, possessing western beliefs, and are more likely to be happy, compared to their counterparts. As expected, the results reveal that the likelihood of being happy is higher for those who have received medical benefits, as well as those persons without housing problems or financial difficulties, compared to their excluded counterparts. However, no significant association is found between happiness and some social exclusion domains, such as child and youth benefits, and unemployment benefits.ConclusionsThe disengagement of the indigenous peoples in mainstream society, with respect to the accessibility of welfare provisions, is a crucial element in regard to social exclusion and happiness. Several policy implications for the social sustainability of indigenous peoples can be inferred from these findings. For example, providing a mobile clinical tour, on-site health counseling, or homecare service can contribute to the removal of institutional and geographic barriers to medical welfare provisions for the mountain indigenes. Moreover, the government may devote more welfare resources to assist indigenous families and tribal communities to develop their own social safety net, instead of the individual-oriented welfare provisions. 相似文献

This paper explores the identities that North American lifestyle migrants in Ecuador adopt as they adjust to life in a new racialized social environment. It is based on qualitative interviews with migrants from North America, as well as ethnographic field notes. North Americans describe their growing community in racialized terms and adopt a series of practices that demonstrate anxiety about their position in the racialized social order of Ecuador. The paper discusses the strategies that North American migrants engage in to diminish the importance of their racialized identities in Ecuador. I identify two main practices that complicate North American incorporation in Ecuador: self-policing practices that aim to optimize Ecuadorians' perceptions of them; and desires for integration and ethnic mobility, which seek to erase their ‘Otherness’. 相似文献

This paper examines social determinants of resource competition among Tsimane Amerindian women of Bolivia. We introduce a
semi-anonymous experiment (the Social Strategy Game) designed to simulate resource competition among women. Information concerning
dyadic social relationships and demographic data were collected to identify variables influencing resource competition intensity,
as measured by the number of beads one woman took from another. Relationship variables are used to test how the affiliative
or competitive aspects of dyads affect the extent of prosociality in the game. Using a mixed-modeling procedure, we find that
women compete with those with whom they are quarreling over accusations of meat theft, mate competition, and rumor spreading.
They also compete with members of their social network and with those who were designated as cooperative helpers or as close
kin. Women take fewer beads from desired friends, neighbors, and from those viewed as enemies. We interpret favoritism toward
enemies as resulting from fear of retribution. Our results suggest that social relations among women are multifaceted and
often cannot be simplified by exclusive focus on genetic relatedness, physical proximity, or reciprocity. We argue that a
complex understanding of cooperation and competition among women may require important contextual information concerning relationship
history in addition to typical features of resource ecology. 相似文献

Children's social skills are an important class of learned behaviors that facilitate success in the classroom; the primary method used in the assessment of social skills involves having parents or teachers complete standardized checklists using judgments of frequency or intensity. Children's (N = 1,102) social skills were modeled as time-varying predictors of student achievements within a latent growth curve model that allowed for estimation of student level variation and the possibility of non-linear achievement growth across 4–5 years of age and grades one, three, and five. Separate models were examined to determine whether ratings provided by mothers' accounted for more achievement score variance than ratings provided by teachers', and multi-group time-varying conditional latent growth curve models were investigated for boys and girls separately by informant type. Results indicated that children's social skills accounted for levels of achievement score variance that were most pronounced at pre-school age, that teachers' ratings of children's social skills generally accounted for more achievement score variance than those obtained by mothers' regardless of the child's sex, and that the explanatory power of social skills for boys and girls was dependent upon the type of achievement considered. 相似文献

Brook trout feed primarily on prey items for which they have developed a search image. Periodically, fish are required to update their search images to match temporal variability in prey abundance. It is currently unknown how brook trout develop search images, but there is evidence to suggest that it could be influenced by social learning, wherein a fish learns a novel behavior through observation alone. Here we demonstrate that adult brook trout use social learning to quickly develop search images for novel prey. We trained a set of demonstrators to develop a search image for canned mealworms and subsequently moved demonstrators to treatment pools that contained naïve bystanders. We also had control pools that contained naïve bystanders and sham demonstrators that had not been trained on mealworms. Over an 8-day period, bystanders in treatment pools consumed 68 % of mealworms, compared to only 36 % in control pools. Moreover, social learning of search images was rapid as bystanders in treatment pools began feeding on mealworms in less than 1 day, whereas it took 7 days for bystanders in control pools to feed heavily on mealworms. Social learning of search images confers an adaptive advantage by reducing energetic costs of foraging. 相似文献
