ABSTRACTThis is the first study to examine the early history of the Israeli transgender community. It covers three decades of transgender activity, from Rina Nathan’s public campaign in the 1950s to permit gender confirmation surgeries in the country to the decision in 1986 to allow surgeries in one public hospital after a lengthy vetting process that de facto held up or disqualified the great majority of applications. The main focus of this study is the generation of “founding mothers” of the transgender community in the 1960s and 1970s and their quest to obtain knowledge, medical technology and paperwork necessary for their gender journeys. We argue that decades before the creation of the internet, Israeli trans pioneers crossed domestic and international boundaries (both social and spatial) and created a network, which later generations of transgender women and men would depend on. This article relies on oral history, contemporaneous media reports and archival documents. 相似文献

In this paper, we examined the psychometric properties of cross‐cultural validation and replicability (i.e. measurement invariance) of the Belief in a Zero‐Sum Game (BZSG) scale, measuring antagonistic belief about interpersonal relations over scarce resources. The factorial structure of the BZSG scale was investigated in student samples from 36 countries (N = 9907), using separate confirmatory factor analyses (CFAs) for each country. The cross‐cultural validation of the scale was based on multigroup confirmatory factor analyses (MGCFA). The results confirmed that the scale had a one‐factor structure in all countries, in which configural and metric invariance between countries was confirmed. As a zero‐sum belief about social relations perceived as antagonistic, BZSG is an important factor related to, for example, social and international relations, attitudes toward immigrants, or well‐being. The paper proposes different uses of the BZSG scale for cross‐cultural studies in different fields of psychology: social, political, or economic. 相似文献

Mixture analysis of count data has become increasingly popular among researchers of substance use, behavioral analysis, and program evaluation. However, this increase in popularity seems to have occurred along with adoption of some conventions in model specification based on arbitrary heuristics that may impact the validity of results. Findings from a systematic review of recent drug and alcohol publications suggested count variables are often dichotomized or misspecified as continuous normal indicators in mixture analysis. Prior research suggests that misspecifying skewed distributions of continuous indicators in mixture analysis introduces bias, though the consequences of this practice when applied to count indicators has not been studied. The present work describes results from a simulation study examining bias in mixture recovery when count indicators are dichotomized (median split; presence vs. absence), ordinalized, or the distribution is misspecified (continuous normal; incorrect count distribution). All distributional misspecifications and methods of categorizing resulted in greater bias in parameter estimates and recovery of class membership relative to specifying the true distribution, though dichotomization appeared to improve class enumeration accuracy relative to all other specifications. Overall, results demonstrate the importance of accurately modeling count indicators in mixture analysis, as misspecification and categorizing data can distort study outcomes. 相似文献

Subgroup analyses allow us to examine the influence of a categorical moderator on the effect size in meta‐analysis. We conducted a simulation study using a dichotomous moderator, and compared the impact of pooled versus separate estimates of the residual between‐studies variance on the statistical performance of the Q B (P) and Q B (S) tests for subgroup analyses assuming a mixed‐effects model. Our results suggested that similar performance can be expected as long as there are at least 20 studies and these are approximately balanced across categories. Conversely, when subgroups were unbalanced, the practical consequences of having heterogeneous residual between‐studies variances were more evident, with both tests leading to the wrong statistical conclusion more often than in the conditions with balanced subgroups. A pooled estimate should be preferred for most scenarios, unless the residual between‐studies variances are clearly different and there are enough studies in each category to obtain precise separate estimates. 相似文献

Mediation analyses have provided a critical platform to assess the validity of theories of action across a wide range of disciplines. Despite widespread interest and development in these analyses, literature guiding the design of mediation studies has been largely unavailable. Like studies focused on the detection of a total or main effect, an important design consideration is the statistical power to detect indirect effects if they exist. Understanding the sensitivity to detect indirect effects is exceptionally important because it directly influences the scale of data collection and ultimately governs the types of evidence group-randomized studies can bring to bear on theories of action. However, unlike studies concerned with the detection of total effects, literature has not established power formulas for detecting multilevel indirect effects in group-randomized designs. In this study, we develop closed-form expressions to estimate the variance of and the power to detect indirect effects in group-randomized studies with a group-level mediator using two-level linear models (i.e., 2-2-1 mediation). The results suggest that when carefully planned, group-randomized designs may frequently be well positioned to detect mediation effects with typical sample sizes. The resulting power formulas are implemented in the R package PowerUpR and the PowerUp!-Mediator software (causalevaluation.org). 相似文献

This article offers a historical and institutional overview of the discipline of religious studies in Korea. It first reviews four early sources of comparative studies: work by Christian missionaries; by Japanese scholars during the period of colonization by that nation; by nationalist Korean scholars who reacted against colonization; and by Korean Christian theologians. The founding of the Korean Association for the History of Religions (KAHR) in 1969 was a key point in the professionalization of the discipline. The field became more firmly established in the late 1980s and early 1990s and has diversified in recent years with a new generation of often foreign-trained scholars. The article ends with a brief discussion of potential contributions that the discipline could make to current debates of national significance. 相似文献

We describe our ethics‐driven process of addressing missing data within a social network study about accountability for racism, classism, sexism, heterosexism, cis‐sexism, ableism, and other forms of oppression among social justice union organizers. During data collection, some would‐be participants did not return emails and others explicitly refused to engage in the research. All refusals came from women of color. We faced an ethical dilemma: Should we continue to seek participation from those who had not yet responded, with the hopes of recruiting more women of color from within the network so their perspectives would not be tokenized? Or, should we stop asking those who had been contacted multiple times, which would compromise the social network data and analysis? We delineate ways in which current discussions of the ethics of social network studies fell short, given our framework and our community psychology (CP ) values. We outline literature that was helpful in thinking through this challenge; we looked outside of CP to the decolonization literature on refusal. Lessons learned include listening for the possible meanings of refusals and considering the level of engagement and the labor required of participants when designing research studies. 相似文献

This study compared motor actions and spatiotemporal changes between weight divisions from Ultimate Fighting Championship (UFC™), conducting a practical application for mixed martial arts (MMA) training. For this, we analyzed 2814 rounds of all weight divisions by motor actions and spatiotemporal changes according actions and time of the Keeping distance, Clinch and Groundwork combat phases. We observed differences between weight divisions in the keeping distance on stand-up combat (p ≤ 0.001; with lower time in Featherweight 131.4 s and bantamweight 127.9 s) clinch without attack (p ≤ 0.001; with higher timer in Flyweight 11.4 s and Half-middleweight 12.6 s) and groundwork without attack (p ≤ 0.001; with higher timer in Half-middleweight 0.9 s). During keeping distance, half-middleweight presented a higher frequency of Head Strikes Landed (p = 0.026; 7 ± 8 times) and attempted (p = 0.003; 24 ± 22 times). In clinch actions heavyweight present a higher frequency (p ≤ 0.023) of head strike landed (3 ± 7 times) and attempted (4 ± 9 times) and half-middleweight for body strikes (p ≤ 0.023) landed (2 ± 5 times) and attempted (3 ± 5 times). At the last, during groundwork, Bantamweight present a higher frequency (p ≤ 0.036) of head strikes landed (8 ± 10 times) and attempted (10 ± 13 times) body strikes landed (p ≤ 0.044; 3 ± 5 times) and attempted (3 ± 6 times). This study reveals important point to training and provide a challenge applied referential to the conditioning plains. From the weight divisions differences should be aware of the increase in the frequency of distance actions, especially in light and middleweights. On the Ground, bantamweight can focus on striking and grappling actions than others. 相似文献

Everyday life is full of self‐control problems. The economist's favorite explanation for self‐control problems is present bias. This paper tests whether experimentally elicited present bias predicts self‐control problems in everyday life. We measure present bias by using a standard incentivized delay discounting task and everyday self‐control by using the day reconstruction method (DRM). Because this is the first study to measure everyday self‐control by using the DRM, we also validate the method by showing that its data replicate key results from the seminal Everyday Temptation Study. We find that present bias does not predict everyday self‐control. This points to a distinction between decreasing impatience (as measured in delay discounting tasks) and visceral influences (as occurring in everyday life) as determinants of self‐control problems. We argue that decision making research can benefit from the DRM as a cost‐effective tool that complements lab and field experiments to better understand economic preference measures and their correlates in everyday life decision making.
