Culture, Modernization, and Politics: Ethnic Differences in Union Formation in Kyrgyzstan

The unique cultural and political history of Central Asia has produced intriguing ethnic variations in union formation. We use data from a survey of 1,535 young adults conducted in 2005 in northern Kyrgyzstan to examine ethnic patterns of entry into marriage versus cohabitation. To reflect the historic-cultural and political realities of Kyrgyzstan, we subdivide ethnic Kyrgyz into two categories based on the degree of linguistic Russification??more-Russified Kyrgyz and less-Russified Kyrgyz??and compare them to each other and to respondents of European origin. The results of the multinomial discrete-time logit models show significant differences among the three groups. Thus, Europeans were most likely to enter cohabitation whereas less-Russified Kyrgyz were least likely to do so, net of other factors. The three groups were lined up in the converse order with respect to probability of entering marriage, but upon breakdown by gender this ordering was present only among women. In contrast, among men, more-Russified Kyrgyz were less likely to marry than both less-Russified Kyrgyz and Europeans. We interpret these findings in light of long-term historic-cultural and demographic distinctions as well as more recent politically induced cleavages in Kyrgyzstan.     

Inference on Counterfactual Distributions

Counterfactual distributions are important ingredients for policy analysis and decomposition analysis in empirical economics. In this article, we develop modeling and inference tools for counterfactual distributions based on regression methods. The counterfactual scenarios that we consider consist of ceteris paribus changes in either the distribution of covariates related to the outcome of interest or the conditional distribution of the outcome given covariates. For either of these scenarios, we derive joint functional central limit theorems and bootstrap validity results for regression‐based estimators of the status quo and counterfactual outcome distributions. These results allow us to construct simultaneous confidence sets for function‐valued effects of the counterfactual changes, including the effects on the entire distribution and quantile functions of the outcome as well as on related functionals. These confidence sets can be used to test functional hypotheses such as no‐effect, positive effect, or stochastic dominance. Our theory applies to general counterfactual changes and covers the main regression methods including classical, quantile, duration, and distribution regressions. We illustrate the results with an empirical application to wage decompositions using data for the United States. As a part of developing the main results, we introduce distribution regression as a comprehensive and flexible tool for modeling and estimating the entire conditional distribution. We show that distribution regression encompasses the Cox duration regression and represents a useful alternative to quantile regression. We establish functional central limit theorems and bootstrap validity results for the empirical distribution regression process and various related functionals.     

Development of a Measure of College Students' Adherence to Religious Doctrine Concerning Sexual Behavior

Abstract

Objective: The authors developed a 14-item measure of adherence to religious doctrine concerning sexual behavior (ARDSB). The ARDSB psychometric properties were investigated to better understand religious motivations associated with changes in sexual behavior that may provide support for sexual health promotion and prevention programs. Participants: Four hundred eighty-three undergraduates aged 18 to 26. Methods: Data were collected from an online survey during the 2012–2013 academic school year. Results: Principle components factor analysis identified 2 factors: reasons to break religious doctrine and reasons to adhere to religious doctrine concerning sexual behavior. The subscales had good internal consistency. Correlations, t tests, and analyses of variance of the subscales with measures of intrinsic and extrinsic religiosity and self-reported sexual behavior and risk provide support for concurrent validity. Conclusions: The ARDSB could be employed as a measure to better understand sexual behavior; it is inexpensive and relatively easy to employ in both research and campus ministry settings.     

From Detention Camps of Thailand to Freedom in the Foothills of North Carolina: One Family’s Remarkable Story

In the 1980s, a number of Hmong families relocated from Thailand detention camps to the United States. This research explores one such family. The family became the key informant in snowball sampling for a larger, ongoing study. Following a series of interviews, qualitative narrative life stories were created and themes of family preservation, survival, and perpetuation of Hmong culture began to emerge. Importantly, parental concerns about how to keep the family intact despite different levels of acculturation surfaced during the process. The purpose of this research was to examine one family’s attempts to preserve the oral history of the Hmong culture and to promote understanding across generations and community members from different cultural backgrounds. The interviews gave the family a forum to expose and discuss their secret journey along with their sacrifices and triumphs. Significantly, the sense of urgency to blend the Hmong and American cultures was profound.     

Diagnostic significance of free salivary testosterone measurement using a direct luminescence immunoassay in healthy men and in patients with disorders of androgenic status

The accurate measurement of testosterone remains a challenge. The determination of the blood testosterone concentrations in serum by conventional immunoassays is inaccurate in men and even more so in females and children. A new luminescence enzyme immunoassay (LIA) has been developed and validated. The high analytical (8.7 pmol/L) and functional (17.3 pmol/L) sensitivity allows the quantification of the very low concentration in saliva, as well as in serum, after 1/40 dilution. This study measured salivary testosterone levels and compared the results with the free levels calculated from total testosterone and sex hormone-binding globulin in eugonadal and hypogonadal men. Salivary testosterone concentrations in healthy men in morning hours were 369 pmol/L (mean), range 263–544 pmol/L, which was statistically significantly higher than that in men with androgen deficiency, 215 pmol/L (mean), range 51–249 pmol/L.

Repetitive determination of free testosterone concentrations in saliva (once a week for 5 weeks) showed high stability of results over time, with coefficient of variation 9% (range 5–23%).

In this study we showed that free salivary testosterone levels in morning samples correlated well with calculated free testosterone in blood, both in healthy men (R = 0.754, P = 0.001), and in patients with androgen deficiency (R = 0.889, P = 0.0001), though in cases with very low testosterone, salivary concentrations were systematically higher than calculated free testosterone levels in blood.     

Effects of foster care placement on biological children in the home

This project used questionnaires to investigate the effects of foster care on biological children in the foster home setting. In southeast Iowa, 52 foster parents and 51 biological children voluntarily responded. Approximately 77% of the foster parents were concerned about the effects of foster care on their biological children—in particular, that biological children felt left out of the family unit. The majority of the foster parents stated that sharing of parental attention should be discussed with biological children before beginning, and both parents and children felt that pretraining sessions for biological children would help their adjustment to foster care.     

为21世纪构建安全的全球能源新体系

过去的10年,关于全球能源体系的预期已经发生非常显著的变化。在经历了长期的产能过剩之后,从2001年开始,全球能源市场中大部分能源产品的价格急速上升,能源供应链也极不稳定。全球油价在持续上升18个月之后达到了历史最高水平,而后下降了2/3。此后,在全球经济持续疲软的影响之下,油价再度上扬至令人担忧的水平。事实上,令人担忧的远远不只油价上扬。例如,欧洲各国政府担心天然气供应的安全,印度等
