Mapping out the interpersonal boundary stones in contemporary China: Guanxi network structure and its association with traditional culture endorsement.

Guanxi research would benefit from an empirical description of holistic guanxi network structures and consideration of sociologically meaningful antecedents such as one's cultural value endorsement. This study, inspired by the relational sociology and drawing on the reported trustworthiness of a rich array of referees in one's guanxi network collected from the Traditional Culture and Cognitive Pattern Survey, identifies two types of guanxi network structures in contemporary China: one is featured by the binary distinction between family and non-family referees, and the other displays a fourfold classification scheme, respectively concerning parents, nuclear family members (children and spouse), other relatives and close friends, and acquaintances. Furthermore, traditional culture endorsement is positively correlated with the likelihood of being subject to the binary classification scheme, while some counter social forces, such as the establishment of quasi-kinship relationships, encourage one to lean toward the more fine-grained fourfold guanxi network partitioning.

Heterogeneous treatment effects analysis for social scientists: A review.

Social scientists have long been interested in the varying responses to a specific intervention, motivating the enterprise of heterogeneous treatment effects (HTE) analysis. Over the past five decades, the rapid development of HTE methods, from conventional multiplicative interactions in linear models to explorations based on machine learning techniques, has been witnessed. This article presents a systematic review of major HTE methods, including multiplicative interaction modeling, generalized additive modeling, propensity-score-based methods, marginal treatment effect, separate LASSO constraints, causal trees, causal forests, Bayesian additive regression trees, and meta-learners (i.e., the S-learner, T-learner, X-learner, and R-learner). These methods, as described roughly in a chronological order to emphasize methodological developments, are addressed to highlight their respective strengths and limitations. Following an illustrative example, this article reflects on future methodological developments.

Outward specific trust in the balancing of hierarchical government trust: Evidence from mainland China.

This study elaborates the link between social trust and government trust by investigating how the extent of outwardness in one's specific trusting relation, as coalescence of trust strength and radius, relates to the varying trust in governments of different administrative levels. Using survey data collected in China, a country featured by the hierarchical government trust and differential mode of interpersonal association, we show that, in both urban and rural areas, the outward orientation of interpersonal trust is positively associated with the trust in the subnational governments, while being independent from the confidence in the central government, suggesting a less hierarchical and more balanced attitude toward government trust. One's generalized trust fails to show such a pattern. This study illustrates a handy measure that combines trust radius and trust strength and highlights the relevance of specific trust for political attitudes in an authoritarian regime.

Can greater reliance on test scores ameliorate the association between family background and access to post-collegiate education? Survey evidence from the Beijing College Students Panel survey.

We evaluate whether greater reliance on test scores may reduce the extent of educational inequality by family origin as college graduates seek entrance to graduate school. In this article, we present a case study using survey data of colleges in Beijing, China, where students' performance in standardized graduate school entrance examination (the GSEE) is the primary determinant for the entrance to graduate school. Using multiple waves of the Beijing College Students Panel Survey (BCSPS), we fit a series of models to capture the correlations of family socio-economic status (SES) with the probabilities of seeking entrance to post-collegiate education, registering for and taking the GSEE, and finally obtaining admission to graduate school. After balancing the differential probabilities of seeking graduate level education, we find that family SES is not significantly associated with the likelihood of taking the GSEE, but significantly predicts the probability of applying a foreign graduate program. Although family SES can be marginally correlated with the odds of being admitted by a domestic graduate program, the strength of such an association is significantly weaker than for overseas programs. It is also shown that, for the elite graduate programs, family origin is independent from both GSEE registration and subsequent admission. These findings suggest that the test-oriented evaluations could ameliorate the extent of inequality at the post-collegiate level.

Detecting affiliation in colaughter across 24 societies.

Laughter is a nonverbal vocal expression that often communicates positive affect and cooperative intent in humans. Temporally coincident laughter occurring within groups is a potentially rich cue of affiliation to overhearers. We examined listeners' judgments of affiliation based on brief, decontextualized instances of colaughter between either established friends or recently acquainted strangers. In a sample of 966 participants from 24 societies, people reliably distinguished friends from strangers with an accuracy of 53-67%. Acoustic analyses of the individual laughter segments revealed that, across cultures, listeners' judgments were consistently predicted by voicing dynamics, suggesting perceptual sensitivity to emotionally triggered spontaneous production. Colaughter affords rapid and accurate appraisals of affiliation that transcend cultural and linguistic boundaries, and may constitute a universal means of signaling cooperative relationships.

Relative deprivation in context: How contextual status homogeneity shapes the relationship between disadvantaged social status and health.

We examine the relationship between disadvantaged social status and adverse health outcomes within a context-contingent thesis of relative deprivation. We argue that the health effect of low relative status depends on contextual status homogeneity, which is measured as income inequality and group diversity. Applying mixed-effect modeling to the pooled 2011-2013 Chinese General Social Survey and exploring the cross-level interactions, we found that 1) people in the bottom socioeconomic quartile report significantly better health when contextual income inequality is lower; 2) racial-ethnic minorities report significantly better health when contextual ethnic diversity is higher; and 3) religious minorities also report significantly better health when contextual religious diversity is higher. Ethnic minorities and Muslims even report better health than the majorities in highly diverse contexts. Thus, contextual status homogeneity can modify or even eliminate the health disparities caused by relative deprivation. The context-level moderation of relative deprivation may be explained by the processes of social comparison, institutional resources, and social capital formation. Our findings suggest that health disparities are an interactive product of contextual homogeneity and individual's relative deprivation, and underscore the importance of the nature of the social environment where relative deprivation occurs. In this way, we contribute to knowledge about reducing health disparities along the social gradient.

Science or liberal arts? Cultural capital and college major choice in China.

Previous studies on major East Asian societies such as Japan and Korea generally fail to find a strong effect of cultural capital in educational inequality, partly due to the characteristic extreme focus on standardized test and curriculum. This study shifts attention to the horizontal stratification of education by investigating the association between family background, cultural capital, and college major choice in contemporary China. Based on analysis of data from the Beijing College Students Panel Survey (BCSPS), we found that, on average, cultural capital significantly mediates the relationship between family background and college major preference. Those with greater endowment of cultural capital are more likely to come from socio-economically advantaged families, and, at the same time, demonstrate a stronger propensity to major in liberal arts fields rather than science, technology, engineering and mathematics (STEM) fields. Further analyses reveal that the association between cultural capital and academic field choice comes into being by way of performance in the Chinese test in the national college entrance examination and of the non-cognitive dispositions, such as self-efficacy and self-esteem. Our findings better our understanding of formation of the horizontal stratification of higher education.

The Perception of Spontaneous and Volitional Laughter Across 21 Societies.

Laughter is a nonverbal vocalization occurring in every known culture, ubiquitous across all forms of human social interaction. Here, we examined whether listeners around the world, irrespective of their own native language and culture, can distinguish between spontaneous laughter and volitional laughter-laugh types likely generated by different vocal-production systems. Using a set of 36 recorded laughs produced by female English speakers in tests involving 884 participants from 21 societies across six regions of the world, we asked listeners to determine whether each laugh was real or fake, and listeners differentiated between the two laugh types with an accuracy of 56% to 69%. Acoustic analysis revealed that sound features associated with arousal in vocal production predicted listeners' judgments fairly uniformly across societies. These results demonstrate high consistency across cultures in laughter judgments, underscoring the potential importance of nonverbal vocal communicative phenomena in human affiliation and cooperation.

Radius of trust: Gradient-based conceptualization and measurement.

The radius of trust - the width of one's cooperation circle - has been widely cited by scholars from various disciplines as a key factor in the production and maintenance of public good. However, the vagueness in its conceptualization, measurement, and analysis obstructs efficient communication between empirical works, impeding the accumulation of scientific knowledge. This study develops a conceptualization of trust radius as the gradient in the level of trust in specific individuals across social ties of differing strengths. Along with this conceptualization, a new measurement scheme is constructed, which, relative to previous measures, is empirically easy-to-implement and theoretically valid in displaying individual-level variations in trust radius, highlighting trust radius' distinction from generalized trust and affinity with specific trust, and accommodating the differing tie strengths within one's trust network. Finally, this measurement scheme is well integrated in a multilevel modeling framework to study the determinants of trust radius, which is illustrated by two examples.

Changing perceived importance of religion in mainland China, 1990-2012: An age-period- cohort analysis.

The comprehensive social reform and relaxation of religious regulation in mainland China have encouraged scholars to propose a revival thesis of religion, predicting a rising prevalence of religious adherence in the Reform Era. This study extends the revival thesis by focusing attention on people's subjective religiosity, and investigates age, period, and cohort effects on the transition in perceived importance of religion from 1990 to 2012. Capitalizing on the repeated cross-sectional data of the China sample in the World Values Survey, this study shows that (1) The senior population, relative to the younger counterpart, attaches greater importance to religion. (2) The net period effect suggests that Chinese citizens' perceived importance of religion follows an upward trend by the early 2000s, but no significant growth is detected henceforward. (3) The cohorts who experienced the anti-religion Mao's Era in their adolescent life course stage have an evidently lower probability of viewing religion to be important, in relation to the cohorts of the Reform Era. Theoretical implications of the empirical age-period-cohort patterns for the religious economies theory and change of Chinese religious landscape are discussed.

Does higher education expansion promote educational homogamy? Evidence from married couples of the post-80s generation in Shanghai, China.

The expansion of higher education witnessed in many societies influences the pattern of educational assortative mating. Structural transition theory predicts growing educational homogamy due to increasing preference for highly-educated partners who become more widely available. In contrast, social closure theory suggests depressed educational homogamy because the inflation of the education elite circle fosters the openness of marriage market, reducing the preference for a highly-educated mate and increasing the penetrability across social-status boundaries. Capitalizing the survey data that are representative of the post-80s one-child generation collected in Shanghai, China, we test the hypotheses derived from the two theories. Empirical results suggest that, with increasing availability of highly educated individuals, the extent of educational homogamy by birth cohort reveals a U-shaped pattern. This U-shaped pattern demonstrates increasing levels of educational homogamy and lends support to structural transition theory.

A loosening tray of sand? Age, period, and cohort effects on generalized trust in Reform-Era China, 1990-2007.

This study examines the transition of generalized trust in mainland China from 1990 to 2007. Using the methodology of intrinsic estimator to analyze the repeated cross-sectional survey data from the World Values Survey, we separate age, period, and cohort effects on the extent of generalized trust of Chinese citizens. Empirical findings suggest that (1) There is a declining trend in the level of generalized trust across different periods from 1990 to 2007, net of age and cohort effects; (2) People's confidence in an ordinary social member increases as they age, a pattern resembling that of many Western societies; (3) The cohorts that experience the totalitarian Mao's Era in the formative stage of their life course stand out in evidently lower trust in generalized others, relative to those cohorts with formative stage falling in the Reform Era.

Changes in college attainment and the economic returns to a college degree in urban China, 2003-2010: implications for social equality.

Expansion of higher education is expected to reduce social inequality under the conditions that (1) higher education should become increasingly egalitarian; (2) educational attainment should be the main determinant of class destinations; and (3) individuals from different social backgrounds should benefit from higher education homogeneously. Using representative data collected in mainland China from 2003 to 2010, we find (1) social background factors, especially parents' education, are significantly associated with the opportunity of completing college across periods; (2) the economic returns to a college degree have been longitudinally increasing; and (3) for both 2003 and 2010, people from different social origins benefit from higher education attainment in a homogeneous way. An overall assessment of the findings suggests that changes in college attainment and the returns to higher education in urban China are not in favor of the promotion of general social equality, but maintain the existing extent of inequality.

Public sector employment, relative deprivation and happiness in adult urban Chinese employees.

The decline in perceived happiness within economic prosperity in Chinese society calls for further examination. In this research, we investigate the effect of employment in public sector work units on perceived happiness through the mediation of economic and social status relative deprivations. In the reform era of China, work unit is still an important mechanism maintaining social inequality, and those working in government/Communist Party agencies and public institutions have advantages of getting access to high wage, comprehensive welfare and the manipulation of administrative public power. Such economic and social status advantages are expected to reduce their relative deprivation and further promote their perceived happiness. Using a nationwide survey data conducted in 2006, we find working in public sector can significantly reduce the odds of experiencing economic relative deprivation, which is further contributive to the improvement of subjective wellbeing.

Inter-observer agreement of computed tomography and magnetic resonance imaging on gross tumor volume delineation of intrahepatic cholangiocarcinoma: an initial study.

BACKGROUND: Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver tumor, and local radiotherapy has a positive effect on patients with an unresectable tumor. Accurate delineation of gross tumor volume (GTV) is crucial to improve the efficacy of radiotherapy. The purpose of this article was to evaluate the consistency of CT, diffusion weighted imaging (DWI) and Gadoxetic acid disodium (Gd-EOB-DTPA)-enhanced MRI on GTV delineation of ICC. METHODS: Fourteen patients with ICC underwent CT (Plain and Portal, CT scans before and 70 s after the injection of Omnipaque, respectively), DWI, and Gd-EOB-DTPA-enhanced MRI (EOB 70 s and EOB 15 min, mDIXON scans at 70 s and 15 min after the injection of Gd-EOB-DTPA, respectively) examinations before radiotherapy. Volumes of GTV delineation on CT and MRI images were recorded. Dice similarity coefficient (DSC) was calculated to evaluate the spatial overlap. RESULTS: Tumor volume on DWI and EOB 15 min were larger than that on EOB 70 s significantly (both P=0.004). DSC of DWI was significantly larger than that of other CT and MRI sequences (all P≤0.002). DSC of EOB 15 min tended to be larger than that of other CT sequences and EOB 70 s, however, without significances (all P>0.005). Significant correlation was found between DSC and tumor volume (R=0.35, P=0.003). CONCLUSIONS: DWI had significantly higher agreement on GTV delineation of ICC. GTV delineations of ICC on Gd-EOB-DTPA-enhanced MRI showed excellent inter-observer agreement. Fusion of CT and MRI images should be considered to improve the accuracy of GTV delineation.

Modification and comparison of CT criteria in the preoperative assessment of hepatic arterial invasion by hilar cholangiocarcinoma.

OBJECTIVE: To compare the diagnostic performance of three CT criteria and two signs in evaluating hepatic arterial invasion by hilar cholangiocarcinoma. METHODS: In this study, we retrospectively reviewed the CT images of 85 patients with hilar cholangiocarcinoma. Modified Loyer's, Lu's, and Li's standards were used to evaluate hepatic arterial invasion by hilar cholangiocarcinoma with the reference of intraoperative findings and/or the postoperative pathological diagnosis. Arterial tortuosity and contact length were also evaluated. RESULTS: Loyer's, Lu's, and Li's standards showed sensitivities of 91.7%, 90.3%, and 72.2%, specificities of 94.0%, 94.5%, and 95.6%, and accuracies of 93.3%, 93.3%, and 89.0%, respectively, in evaluating hepatic arterial invasion by hilar cholangiocarcinoma. Loyer's and Lu's standards and contact length performed better than Li's standard (P < 0.001). Arterial tortuosity performed worse than other criteria (P < 0.001). The CT criteria performed best in evaluating proper hepatic arterial invasion compared with the left and right hepatic artery. When the cut-off contact length of 6.73 mm was combined with Loyer's standard, 4 false-negative cases could be avoided. CONCLUSIONS: Loyer's and Lu's standards and the contact length performed best in evaluating hepatic arterial invasion by hilar cholangiocarcinoma on preoperative CT images, particularly in assessing the proper hepatic artery. Arterial tortuosity could serve as an important supplement. The combination of the contact length and Loyer's standard could improve the diagnostic performance.

An analysis of the interactions between the spine, pelvis, and lower limbs in asymptomatic adults with limited pelvic compensation.

BACKGROUND: The interactions between the spine, pelvis, and lower limbs are dynamic based on the "cone of economy" concept; thus, different global radiographic parameters could be regarded as reflections of different centers of gravity. We conducted this retrospective study to evaluate the offsets of different centers of gravity in asymptomatic populations and to investigate how the global sagittal alignment is supported. METHODS: The following parameters were measured: cervical lordosis, thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), the ratio between PT and PI (PT/PI), sacral slope, PI minus LL (PI-LL), the sagittal vertical axis (SVA), cranial SVA to ankle center (Cr-A), CrSVA to the femoral head center (Cr-FH), C2SVA to the femoral head center (C2-FH), pelvic translation (P. Shift), and knee angle (KA). Participants were divided into subgroups based on the PT/PI ratio. Mean values were compared using the t-test, and correlations were assessed using Pearson's coefficient. RESULTS: A total of 82 asymptomatic adults were enrolled. The average PT/PI in subgroup 1 was the smallest, showing that individuals in this group may have limited pelvic retroversion. No significant differences in Cr-FH, Cr-A, or C2-FH were found between subgroups (all P>0.1), implying that global alignment was well supported in each group. Specifically, C2-FH showed minor changes between subgroups (P=0.998), showing that C2-FH may be a target for sagittal compensation. There were positive correlations between PT/PI and both P. Shift and SVA (r=0.930 and r=0.606, respectively). However, Cr-FH, Cr-A, and C2-FH were not significantly correlated with P. Shift or PT/PI (all P>0.05). Weak correlations existed between Cr-A, Cr-FH, and age (all P>0.2). CONCLUSIONS: This study revealed that the Cr-FH and C2-FH offsets are stable across the population and could be maintained by regulating only the sagittal spinal curvature when pelvic compensation is limited. Cr-FH is not affected by age in the asymptomatic population. Thus, the stable Cr-FH and C2-FH could provide references for surgeons during the surgical decision-making process in patients with adult spinal deformity with sagittal malalignment.

Is college education an equalizer for social disparities in health literacy? A case study in Shanghai, China.

OBJECTIVES: The aim of the study was to illustrate the immediate effect of the college education process (across college grades) on the strength of association between parental education and college attendees' health literacy. METHODS: Cross-sectional analysis was conducted based on data from a random sample of students in one university in Shanghai, China (N = 574). Exploratory factor analysis was used to generate factors of different dimensions of health literacy. Ordinary least square regression models were estimated to investigate how college education process alters the family-based disparity in health literacy. RESULTS: The link between parental education and health-related skills did not vary significantly across grades of participants, but participants in their third (p < 0.05) and fourth year (p < 0.001) revealed a significantly weaker association between health-promoting proactivity and parental education, relative to the first-year counterparts. Also, the impact of parental education on health-related attitudes significantly declined among the fourth-year seniors, compared with first-year students (p < 0.05). CONCLUSIONS: Higher education experience is an important mechanism to alleviate the socioeconomic gap in health literacy. Such an equalizer effect, nevertheless, is contingent on the particular dimensions of health literacy.

Allocation of Eldercare Responsibilities between Children and the Government in China: Does the Sense of Injustice Matter?

China's large aging population poses grim challenges to eldercare provision. Against the background of withering traditional kinship-based eldercare and the increasing significance of government-sponsored support programs, this study draws on data from the 2013 Chinese General Social Survey to investigate not only the correlation between the sense of social injustice and the preference to allocate eldercare responsibilities between public and private agents but also how this correlation varies between urban-versus-rural regions. We find that perceived social injustice is significantly correlated with the odds of designating the government, instead of family members, to shoulder eldercare responsibilities. Further mediation analysis suggests that this correlation is mediated through concerns about eldercare. On average, the link between perceived social injustice and the preference for eldercare duty allocation is weaker in rural China than in urban China. Theoretical and policy implications are discussed.

Which Child Is Parents' Preferred Caregiver/Listener in China?

Adult children are an important source of care providers for parents in a rapidly aging Chinese society, but we know little of which particular child is preferred by parents in time of need. Using the China Longitudinal Aging Social Survey, we investigate the factors associated with parental preference of caregivers and listeners among all his or her children. With children nested within each parent, we fit the conditional (family) fixed-effect fractional logit model. The main results for both caregivers and listeners suggest a preference for the unmarried, the oldest or the youngest, and children who have provided them with support before. Coresident children are favored in rural but not urban China. We did not find preference for sons over daughters. Neither did we find any effect of prior transfers from parents to children. Our findings shed light on the changing norms of eldercare provision in a transitioning society.
