A growing literature has examined the prevalence of transnational engagement among children of immigrants. However, few studies have been equipped to analyse underlying dynamics that serve to impede or perpetuate transnational practices among them in the United States. In this article, we compare transnationalism narratives between 1.5- and second-generation children of immigrants to more fully adjudicate enduring transnational ties over time. Our analysis of 134 interviews from the Children of Immigrants Longitudinal Study suggests that children of immigrants from Southern California conceptualise transnational experiences in diverse but remarkably similar ways. The meanings attached to transnational behaviours and identities employ certain patterns, and are often related to strength of kin-based ties, ethnic language fluency, and levels of structural access to the homeland. Moreover, findings indicate that the second-generation is nearly as transnationally engaged as the 1.5-generation. This provides novel but limited evidence in support of claims that transnational ties are sustained across generations. 相似文献

Changes to the ground layer in urban areas are extensive, but the effects on arthropod fauna are poorly understood. We undertook a manipulative experiment to examine the response of arthropods to small-scale variation in ground covers commonly found in urban parks and gardens in Australia. The ground covers tested were bare ground, leaf litter, woodchips and grass, with plot sizes of 3.6 m2. Epigeic arthropods were sampled with pitfall traps and Tullgren funnels over 12 months following establishment of the treatments. All epigeic arthropods were sorted to order and the ants (Hymenoptera: Formicidae), beetles (Coleoptera), millipedes (Diplopoda) and slaters (Isopoda: Oniscidea) were examined at lower taxonomic levels. Diverse arthropods rapidly colonised previously cleared plots in all four treatments and were most abundant in grass plots. The diversity of ants and beetles was significantly different in different ground covers and tended to be most diverse in grass plots. Despite the treatments providing very different microclimates, the fauna studied did not show strong selection for a particular cover type overall. The abundance of grass cover in the surrounding area may have led to the grass plots having the greatest abundance of arthropods. These results have important implications for developing effective small-scale conservation efforts for arthropods in anthropogenically modified landscapes, especially for species with poor dispersal abilities. 相似文献

Emerging research suggests that existing culture, including religious culture, serves to constrain and enable the rhetoric
and claims of social actors in situations of conflict and change. Given that religious institutions continue to have significant
authority in framing moral debates in the United States, we hypothesize that groups connected to each other through a religious
tradition will share similar orientations towards the moral order, shaping the kinds of rhetoric they use and the kinds of
claims they can make. To test this, we compare the official rhetoric of the 25 largest religious denominations on gay and
lesbian issues, as well as their orientation towards the moral order more broadly, with the rhetoric of each denomination’s
respective movement for lesbian, gay, bisexual, and transgender inclusion, affirmation, or rights. We use Kniss’ heuristic
map of the moral order to analyze and theorize about the patterns that emerge from these comparisons. Ultimately, we find
that the existing rhetoric of the parent denomination on gay and lesbian issues, along with the broader moral stances they
take, do appear to shape the rhetoric and ideologies of associated pro-LGBT organizations. This provides support for the notion
that existing culture, belief, and rhetoric shape the trajectories of conflict and change. 相似文献

Unlike other life domains, sexual quality of life (SQoL) has a negative relationship with age. This study disentangled the effect of age in this relationship from confounding sociocultural influences (e.g., the period of time in which data were collected, and cohort differences) and aimed to understand the roles of other sexual domains (i.e., frequency, perceived control, thought and effort invested in sex, and number of sexual partners). We analyzed data from the longitudinal Midlife in the United States study (n = 6,278; age range 20–93), which were collected between 1995 and 2013. Repeated measures linear mixed-effects models showed that age was the most robust time-related predictor of declining SQoL. However, after the sexual domains were included in the model, age had a positive relationship with SQoL and older adults’ SQoL was differentially influenced by the quality—not quantity—of sex. When partnership characteristics were included in the model, age was no longer related to SQoL. These findings suggest that aging may be associated with the acquisition of skills and strategies that can buffer age-related declines in SQoL, particularly in the context of a positive relationship. We summarize these findings as sexual wisdom. 相似文献

Sexual dysfunctions commonly co-occur with various depressive and anxiety disorders. An emerging framework for understanding the classification of mental disorders suggests that such comorbidity is a manifestation of underlying dimensions of psychopathology (or “spectra”). In this review, we synthesize the evidence that sexual dysfunctions should be included in the empirical taxonomy of psychopathology as part of the internalizing spectrum, which accounts for comorbidity among the depressive and anxiety disorders. The review has four parts. Part 1 summarizes the empirical basis and utility of the empirical taxonomy of psychopathology. Part 2 reviews the prima facie evidence for the hypothesis that sexual dysfunctions are part of the internalizing spectrum (i.e., high rates of comorbidity; shared cognitive, affective, and temperament characteristics; common neural substrates and biomarkers; shared course and treatment response; and the lack of causal relationships between them). Part 3 critically analyzes and integrates the results of the eight studies that have addressed this hypothesis. Finally, Part 4 examines the implications of reconceptualizing sexual dysfunctions as part of the internalizing spectrum, and explores avenues for future research. 相似文献

Interpersonal accuracy correlates modestly across different domains. Although some research has explored factors that predict accuracy within specific domains of interpersonal judgment (e.g., social attributes), whether any variables might predict interpersonal accuracy generally across different domains remains in question. Subjective socioeconomic status (SES) has recently emerged as an important moderator of various social cognitions, such as contextual focus and empathic accuracy. Moreover, people lower in SES tend to show greater interpersonal engagement and attention; thus, we wondered whether individuals with lower subjective SES might exhibit superior interpersonal accuracy in multiple domains. Indeed, across four studies, we found that subjective SES inversely correlated with accuracy in three different domains of interpersonal accuracy: social attributes, situational affect, and emotion. These findings therefore demonstrate that subjective SES may predict broad interpersonal accuracy abilities and suggest that, despite modest relationships between different types of first impression accuracy, the correlates of such accuracy can still operate across domains. 相似文献

ABSTRACTThis national online survey (N = 493) examined the political organization-public relationship (POPR) that voters perceived with their own political party and their opposing political party, as well as voters’ assessment of the credibility of candidates running for president during the primary season of the 2016 election. Results indicated that although credibility assessment of one’s own party’s candidate was much as expected, POPR with the Democratic Party was generally stronger than that with the Republican Party. Data showed no evidence that a poor POPR with one’s own party would drive voters to support interloper candidates. We conclude by reflecting on the importance of POPR with the opposing party and what weak relationships may mean for parties in the long term. 相似文献

Limit of detection (LoD) is a common problem in the analysis of data generated by instruments that cannot detect very small concentrations or other quantities, resulting in left-censored measurements. Methods intended for data that are not subject to this problem are often difficult to modify for censoring. We adapt the simulation-extrapolation method, devised originally for fitting models with measurement error, to dealing with LoD in conjunction with a mixture analysis. The application relates the levels of thyroglobulin in individuals with cancer of the thyroid before and after treatment with radioactive iodine I–131. We conclude that the fitted mixture components correspond to levels of effectiveness of the treatment. 相似文献

ABSTRACTDependence among defaults both across assets and over time is an important characteristic of financial risk. A Bayesian approach to default rate estimation is proposed and illustrated using prior distributions assessed from an experienced industry expert. Two extensions of the binomial model are proposed. The first allows correlated defaults yet remains consistent with Basel II’s asymptotic single-factor model. The second adds temporal correlation in default rates through autocorrelation in the systemic factor. Implications for the predictability of default rates are considered. The single-factor model generates more forecast uncertainty than does the parameter uncertainty. A robustness exercise illustrates that the correlation indicated by the data is much smaller than that specified in the Basel II regulations. 相似文献

The equipment failure distributions commonly identified in practice pose great difficulties in the establishment of sound maintenance total float policy. Some of the existing analytical constructs utilize the reliability ratio of the equipment in operations in order to bypass the obstacles and arrive at applicable solutions. In this paper we give a summary of these theoretical models. In addition, we provide insight by testing the significance of factors utilized in maintenance total float determination. The paper examines the effect of the assumption made by the analytical model of no waiting time for repair. Our test showed that there is no statistically significant difference between the analytical model and simulation when waiting is allowed for the normal and uniform distributions. The analytical model thus offers some advantage in its use to estimate maintenance float due to its simplicity. When failure distribution is an exponential, Erlang-2 or lognormal, the assumption of no waiting time for repair must be kept in order to use the analytical model. 相似文献
