Culture Within: An Exploration of the Effects of Social Class and Region on the Self and Cognitive Habits.

Culture’s psychological impact stretches from some of the most basic perceptual processes to higher order reasoning. Yet much less is known about the impact of group differences within cultures due to factors such as social class, geographic region, or religion. Exploring within-culture differences not only provides insight into the psychological consequences of these factors, but can also inform our understanding of the mechanisms by which cultural differences operate and are maintained. In Chapter 2, I explore the effects of culture and social class on cognitive habits (attribution, patterns of visual attention, and reasoning about change) and symbolic representation of the self. Russians demonstrated more holistic cognitive patterns and less symbolic self-inflation than Americans; people from working-class backgrounds demonstrated more holistic cognitive patterns and less symbolic self-inflation than those from middle-class backgrounds. Furthermore, for both group comparisons, cognitive differences were partially mediated by differences in self-inflation, suggesting a common mechanism may underlie both group differences. In Chapter 3, I examined whether social class differences in causal inference might be due to relatively automatic or controlled processes. Previous research has found that cultural differences in causal inference appear to be due to differences in early-stage processing of personality-relevant information. Using an ERP paradigm, we found results for social class that were largely parallel to the previously observed cross-cultural difference, suggesting that differences in attribution related to culture and to social class both likely arise from automatic inference processes. In Chapter 4, I tested the voluntary settlement hypothesis by exploring regional variation in naming practices both within the US and Canada and comparing countries recently settled by Europeans with European countries. The voluntary settlement hypothesis (Kitayama, et al., 2010) holds that areas that were more recently frontiers both select for individuals who are more independent and promote independent values and behaviors. I found that popular names were less prevalent in US states and Canadian provinces that were more recently frontiers. The same pattern was observed comparing countries recently settled by Europeans with European countries, suggesting that the settling of frontiers has led to parallel differences both across and within countries.Ph.D.PsychologyUniversity of Michigan, Horace H.

Parental cancer diagnosis and child mortality : a population-based cohort study in Sweden

OBJECTIVE: Cancer diagnosis is known to induce severe psychological stress for the diagnosed patients; however, how it affects the next-of-kin is less well documented. This study aimed to assess the impact of parental cancer on the risk of childhood death. METHODS: A population-based cohort study was conducted using the Swedish national registries, including 2,871,242 children followed during the period of 1991-2009. Parental cancer diagnosis was defined as a time-varying exposure. We used Cox proportional hazards regression to calculate the hazard ratio (HR) and its corresponding 95% confidence interval (CI) as an estimate of the association between parental cancer and childhood mortality. We adjusted for attained age, sex, gestational age, mode of delivery and birth weight of the child, maternal age at child's birth, as well as educational level and socio-economic classification of the parents in the analyses. RESULTS: Among 113,555 children with parental cancer, 127 deaths occurred during 561,198 person-years of follow-up. A parental cancer diagnosis was associated with an increased rate of death among children at the age of 1-18 (HR for all-cause death: 1.39; 95% CI: 1.16-1.66). For young children (aged 1-12), an increased rate was only noted for death due to cancer (HR: 2.06; 95% CI: 1.13-3.75) after parental cancer diagnosis. Among adolescents (aged 13-18), an increased rate was noted for all-cause death (HR: 1.52; 95% CI: 1.25-1.86), and for both non-cancer-related (HR: 1.43; 95% CI: 1.14-1.79) and cancer-related (HR: 2.07; 95% CI: 1.33-3.24) death in the exposed children. CONCLUSION: Children have an increased rate of death if they have a parent diagnosed with cancer as compared to children without such experience; this association appears to be slightly stronger among adolescents.Swedish Research CouncilSwedish Research Council for Health Working Life & Welfare (Forte), 2012-0498Swedish Research Council SIMSAM, 80748301, 340-2013-5867China Scholarship Council, 201206100002Swedish Society for Medical Research (SSMF)Karolinska InstitutetPublishe

Hot dense capsule implosion cores produced by z-pinch dynamic hohlraum radiation

Hot dense capsule implosions driven by z-pinch x-rays have been measured for the first time. A ~220 eV dynamic hohlraum imploded 1.7-2.1 mm diameter gas-filled CH capsules which absorbed up to ~20 kJ of x-rays. Argon tracer atom spectra were used to measure the Te~ 1keV electron temperature and the ne ~ 1-4 x10^23 cm-3 electron density. Spectra from multiple directions provide core symmetry estimates. Computer simulations agree well with the peak compression values of Te, ne, and symmetry, indicating reasonable understanding of the hohlraum and implosion physics.Comment: submitted to Phys. Rev.

Increasing population densities predict decreasing fertility rates over time : a 174-nation investigation

Fertility rates have been declining worldwide over the past fifty years, part of a phenomenon known as “the demographic transition.” Prior work suggests that this decline is related to population density. In the present study, we draw on life history theory to examine the relationship between population density and fertility across 174 countries over 69 years (1950 to 2019). We find a robust association between density and fertility over time, both within- and between-countries. That is, increases in population density are associated with declines in fertility rates, controlling for a variety of socioeconomic, socioecological, geographic, population-based, and female empowerment variables. We also tested predictions about environmental boundary conditions. In harsher living conditions (e.g., higher homicide or pathogen rates), the effect of increased population density on fertility rates was attenuated. The density-fertility association was also moderated by religiousness and strength of social norms, where the relationship between density and fertility was attenuated in countries with high religiosity and strong social norms. We discuss why and when changes in population density may influence fertility rates and the broader implications of this work

Validation of the Thai version of the family reported outcome measure (FROM-16)© to assess the impact of disease on the partner or family members of patients with cancer

© The Author(s). 2019Background: Cancer not only impairs a patient's physical and psychosocial functional behaviour, but also contributes to negative impact on family members' health related quality of life. Currently, there is an absence of a relevant tool in Thai with which to measure such impact. The aim of this study was to translate and validate the Family Reported Outcome Measure (FROM-16) in Thai cancer patients' family members. Methods: Thai version of FROM-16 was generated by interactive forward-backward translation process following standard guidelines. This was tested for psychometric properties including reliability and validity, namely content validity, concurrent validity, known group validity, internal consistency, exploratory and confirmatory factor analysis. Construct validity was examined by comparing the Thai FROM-16 version with the WHOQOL-BREF-THAI. Results: The internal consistency reliability was strong (Cronbach's alpha = 0.86). A Negative moderate correlation between the Thai FROM-16 and WHOQOL-BREF-THAI was observed (r = - 0.4545, p < 0.00), and known group validity was proved by a statistically significant higher score in family members with high burden of care and insufficient income. The factor analysis supported both 3-factor and 2-factor loading model with slight difference when compared with the original version. Conclusions: The Thai FROM-16 showed good reliability and validity in Thai family members of patients with cancer. A slight difference in factor analysis results compared to the original version could be due to cross-culture application.Peer reviewedFinal Published versio

Review of high convergence implosion experiments with single and double shell targets

Experiments have been been performed in recent years at the Omega laser studying double shell capsules as an a1 teinative, 11011 cryogenic, path towards ignition at NTF. Double shell capsules designed to mitigate the Au M-band radiation asymmetries, were experimentally found to perform well in both spherical and cylindrical hohlraums, achieving near 1-D (-90 %) clean calculated yield at convergence comparable to that required for NIF ignition. Near-term plans include directly driven double shell experiments at Omega, which eliminates Au M-band radiation as a yield degradation m ec h an i s in

Parental bereavement and the loss of purpose in life as a function of interdependent self-construal

Citation: Parental bereavement and the loss of purpose in life as a function of interdependent self-construal. Front. Psychol. 6:1078. doi: 10.3389/fpsyg.2015 Parental bereavement and the loss of purpose in life as a function of interdependent self-construal Children are often inextricably linked to their parents&apos; hopes and dreams. As such, the loss of a child often represents one of the most traumatic experiences possible. The current research explores how this specific loss relates to one&apos;s sense of purpose in life. We further explore whether the loss of a child is particularly detrimental to one&apos;s sense of purpose for highly interdependent parents. Analyses of parents from the Midlife in the United States data set revealed, as expected, that the loss of child negatively predicts one&apos;s sense of purpose in life, and that this effect is most pronounced for parents high in interdependent self-construal. Potential mechanisms and implications of the present findings are discussed

Aging and Wisdom: Culture Matters

People from different cultures vary in the ways they approach social conflicts, with Japanese being more motivated to maintain interpersonal harmony and avoid conflicts than Americans are. Such cultural differences have developmental consequences for reasoning about social conflict. In the study reported here, we interviewed random samples of Americans from the Midwest United States and Japanese from the larger Tokyo area about their reactions to stories of intergroup and interpersonal conflicts. Responses showed that wisdom (e.g., recognition of multiple perspectives, the limits of personal knowledge, and the importance of compromise) increased with increasing age among Americans, but older age was not associated with wiser responses among Japanese. Younger and middle-aged Japanese showed greater use of wise-reasoning strategies than younger and middle-aged Americans did. This cultural difference was weaker for older participants’ reactions to interpersonal conflicts and was actually reversed for intergroup conflicts. This research has important implications for the study of aging, cultural psychology, and wisdom.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Capsule design for the National Ignition Facility

Several choices exist in the design and production of capsules intended to ignite and propagate fusion burn of the DT fuel when imploded by indirect drive at the National Ignition Facility. These choices include ablator material, ablator dopant concentration and distribution, capsule dimensions, and x-ray drive profile (shock timings and strengths). The choice of ablator material must also include fabrication and material characteristics, such as attainable surface finishes, permeability, strength, transparency to radio frequency and infrared radiation, thermal conductivity, and material homogeneity. Understanding the advantages and/or limitations of these choices is an ongoing effort for LLNL and LANL designers. At this time, simulations in one- two- and three- dimensions show that capsules with either a copper doped beryllium or a polyimide (C22H10N2O4) ablator material have both the least sensitivity to initial surface roughnesses and favorable fabrication qualities. Simulations also indicate the existence of capsule designs based on these ablator materials which ignite and burn when imploded by less than nominal laser performance (900 kJ energy, 250 TW power, producing 250 eV peak radiation temperature). We will describe and compare these reduced scale capsules, in addition to several designs which use the expected 300 eV peak x-ray drive obtained from the nominal NIF laser (1.3 MJ, 500 TW)
