Cultural Patterns of Suicide in the United States: The Role of Honor Culture

New Insights on Cultural Patterns of Suicide in the United States: The Role of Honor Culture. By Marisa Crowder & Markus Kemmelmeier
Cross-Cultural Research, http://journals.sagepub.com/doi/abs/10.1177/1069397117712192

Abstract: Cultural differences in suicide can be indicative of varying social pressures placed on individuals. High suicide rates in U.S. honor cultures have been proposed to reflect pressures associated with maintaining one’s reputation. We extend this argument by highlighting that honor concerns differentially impact individuals based on gender, ethnicity, and age. Controlling for relevant confounds, we show that suicide rates were highest among older European American men from honor cultures, presumably because aging may render these men less capable of conforming to cultural ideals of masculinity. We discuss the need for process-focused and subgroup analyses when examining the effects of culture on suicide.

Variation in the Serotonin Transporter Polymorphism (5-HTTLPR) and Inertia of Negative and Positive Emotions

Variation in the Serotonin Transporter Polymorphism (5-HTTLPR) and Inertia of Negative and Positive Emotions in Daily Life. By Eeske van Roekel et al.
Emotion, doi: 10.1037/emo0000336
https://www.ncbi.nlm.nih.gov/m/pubmed/28569537/

Abstract: An important element of understanding the genotype–phenotype link in psychiatric disorders lies in identifying the psychological mechanisms through which genetic variation impacts mental health. Here we examined whether emotional inertia, the tendency for a person’s emotions to carry over from 1 moment to the next and a prospective predictor of the development of depression, is associated with a known genetic risk factor for emotional dysregulation, a polymorphism in the serotonin transporter gene (5-HTTLPR). Two hundred thirty-six adolescents recorded their positive and negative emotions in daily life 9 times a day for 6 consecutive days using smartphones, completed a depression questionnaire, and were genotyped for the 5-HTTLPR polymorphism. Carriers of the short 5-HTTLPR were characterized by higher inertia for negative emotions, even after controlling for depressive symptoms. These findings suggest a possible psychological pathway how the serotonin transporter gene contributes to risk for depression.

Dying Is Unexpectedly Positive

Dying Is Unexpectedly Positive. By Amelia Goranson et al.
Psychological Science, http://journals.sagepub.com/doi/abs/10.1177/0956797617701186

Abstract: In people’s imagination, dying seems dreadful; however, these perceptions may not reflect reality. In two studies, we compared the affective experience of people facing imminent death with that of people imagining imminent death. Study 1 revealed that blog posts of near-death patients with cancer and amyotrophic lateral sclerosis were more positive and less negative than the simulated blog posts of nonpatients — and also that the patients’ blog posts became more positive as death neared. Study 2 revealed that the last words of death-row inmates were more positive and less negative than the simulated last words of noninmates — and also that these last words were less negative than poetry written by death-row inmates. Together, these results suggest that the experience of dying — even because of terminal illness or execution — may be more pleasant than one imagines.

Child Gender Influences Paternal Behavior, Language, and Brain Function

Child Gender Influences Paternal Behavior, Language, and Brain Function. By Jennifer Mascaro et al.
Behavioral Neuroscience, June 2017, Pages 262-273
http://www.apa.org/pubs/journals/releases/bne-bne0000199.pdf

Abstract: Multiple lines of research indicate that fathers often treat boys and girls differently in ways that impact child outcomes. The complex picture that has emerged, however, is obscured by methodological challenges inherent to the study of parental caregiving, and no studies to date have examined the possibility that gender differences in observed real-world paternal behavior are related to differential paternal brain responses to male and female children. Here we compare fathers of daughters and fathers of sons in terms of naturalistically observed everyday caregiving behavior and neural responses to child picture stimuli. Compared with fathers of sons, fathers of daughters were more attentively engaged with their daughters, sang more to their daughters, used more analytical language and language related to sadness and the body with their daughters, and had a stronger neural response to their daughter's happy facial expressions in areas of the brain important for reward and emotion regulation (medial and lateral orbitofrontal cortex [OFC]). In contrast, fathers of sons engaged in more rough and tumble play (RTP), used more achievement language with their sons, and had a stronger neural response to their son's neutral facial expressions in the medial OFC (mOFC). Whereas the mOFC response to happy faces was negatively related to RTP, the mOFC response to neutral faces was positively related to RTP, specifically for fathers of boys. These results indicate that real-world paternal behavior and brain function differ as a function of child gender.

Less than a third of the 65 Chinese highway & rail projects examined were “genuinely economically productive.”

China’s New Bridges: Rising High, but Buried in Debt. By Chris Buckley
TNYT, Jun 10 2017
China has built hundreds of dazzling new bridges, including the longest and highest, but many have fostered debt and corruption.https://www.nytimes.com/2017/06/10/world/asia/china-bridges-infrastructure.html

“The amount of high bridge construction in China is just insane,” said Eric Sakowski, an American bridge enthusiast who runs a website on the world’s highest bridges. “China’s opening, say, 50 high bridges a year, and the whole of the rest of the world combined might be opening 10.”

Of the world’s 100 highest bridges, 81 are in China, including some unfinished ones, according to Mr. Sakowski’s data. (The Chishi Bridge ranks 162nd.)

China also has the world’s longest bridge, the 102-mile Danyang-Kunshan Grand Bridge, a high-speed rail viaduct running parallel to the Yangtze River, and is nearing completion of the world’s longest sea bridge, a 14-mile cable-stay bridge skimming across the Pearl River Delta, part of a 22-mile bridge and tunnel crossing that connects Hong Kong and Macau with mainland China.

The country’s expressway growth has been compared to that of the United States in the 1950s, when the Interstate System of highways got underway, but China is building at a remarkable clip. In 2016 alone, China added 26,100 bridges on roads, including 363 “extra large” ones with an average length of about a mile, government figures show.

[...]

A study that Mr. Ansar helped write [https://academic.oup.com/oxrep/article/32/3/360/1745622/Does-infrastructure-investment-lead-to-economic] said fewer than a third of the 65 Chinese highway and rail projects he examined were “genuinely economically productive,” while the rest contributed more to debt than to transportation needs. [...]

In the country that built the Great Wall, major feats of infrastructure have long been a point of pride. China has produced engineering coups like the world’s highest railway, from Qinghai Province to Lhasa, Tibet; the world’s largest hydropower project, the Three Gorges Dam; and an 800-mile canal from the Yangtze River system to Beijing that is part of the world’s biggest water transfer project.
Leaders defend the infrastructure spree as crucial to China’s development.

“It’s very important to improve transport and other infrastructure so that impoverished regions can escape poverty and prosper,” President Xi Jinping said while visiting the spectacular, recently opened Aizhai Bridge in Hunan in 2013. “We must do more of this and keep supporting it.”

Indeed, the new roads and railways have proved popular, especially in wealthier areas with many businesses and heavy commuter traffic. And even empty infrastructure often has a way of eventually filling up, as early critics of the country’s high-speed rail and the Pudong skyscrapers in Shanghai have discovered.

Why do some societies fail to adopt more efficient institutions in response to changing economic conditions?

The Ideological Roots of Institutional Change, by Murat Iyigun & Jared Rubin
University of Colorado Working Paper, April 2017
Abstract:Why do some societies fail to adopt more efficient institutions in response to changing economic conditions? And why do such conditions sometimes generate ideological backlashes and at other times lead to transformative sociopolitical movements? We propose an explanation that highlights the interplay - or lack thereof - between new technologies, ideologies, and institutions. When new technologies emerge, uncertainty results from a lack of understanding how the technology will fit with prevailing ideologies and institutions. This uncertainty discourages investment in institutions and the cultural capital necessary to take advantage of new technologies. Accordingly, increased uncertainty during times of rapid technological change may generate an ideological backlash that puts a higher premium on traditional values. We apply the theory to numerous historical episodes, including Ottoman reform initiatives, the Japanese Tokugawa reforms and Meiji Restoration, and the Tongzhi Restoration in Qing China.

Physical Safety Promotes Socially (but Not Economically) Progressive Attitudes among Conservatives

Napier, J. L., Huang, J., Vonasch, A. J., and Bargh, J. A. (2017) Superheroes for Change: Physical Safety Promotes Socially (but Not Economically) Progressive Attitudes among Conservatives. Eur. J. Soc. Psychol., doi: 10.1002/ejsp.2315
http://onlinelibrary.wiley.com/doi/10.1002/ejsp.2315/abstract

Abstract: Across two studies, we find evidence for our prediction that experimentally increasing feelings of physical safety increases conservatives' socially progressive attitudes. Specifically, Republican and conservative participants who imagined being endowed with a superpower that made them invulnerable to physical harm (vs. the ability to fly) were more socially (but not economically) liberal (Study 1) and less resistant to social change (Study 2). Results suggest that socially (but not economically) conservative attitudes are driven, at least in part, by needs for safety and security.

Patients’ crying experiences in psychotherapy: Relationship with the patient level of personality organization, clinician approach, and therapeutic alliance

Patients’ crying experiences in psychotherapy: Relationship with the patient level of personality organization, clinician approach, and therapeutic alliance. By Zingaretti, Pietro; Genova, Federica; Gazzillo, Francesco; Lingiardi, Vittorio
Psychotherapy: Theory, Research, Practice, Training, Vol 54(2), Jun 2017, 159-166.
http://dx.doi.org/10.1037/pst0000110

Abstract: The present study sought to further understand patients’ crying experiences in psychotherapy. We asked 64 clinicians to randomly request one patient in their practice to complete a survey concerning crying in psychotherapy as well as a measure of therapeutic alliance. All clinicians provided information regarding their practice and patient diagnostic information. Fifty-five (85.93%) patients cried at least once, and 18 (28.1%) had cried during their most recent session. Patients’ frequency of crying episodes in therapy was negatively related with psychotic level of personality organization, while patients’ tendency to feel more negative feelings after crying was positively related to lower levels of personality organization. Patients’ feeling more in control after crying was positively related with an interpersonal therapeutic approach, while patients’ perception of therapists as more supportive after crying was positively related to a psychodynamic approach. Patients’ tendency to experience more negative feelings after crying was significantly related with both lower levels of personality organization and patients’ perception of the therapeutic alliance as weak. In regard to their most recent crying event in treatment, therapeutic alliance was related to gaining a new understanding of experience not previously recognized by the patient. Further, patients’ experiences of having never told anyone about their experience related to a crying episode, as well as their realization of new ideas and feeling of having communicated something that words could not express was positively related to the goal dimension of alliance. Patients’ perception of crying as a moment of genuine vulnerability, greater feelings of self-confidence and self-disclosure as well as having had a therapist response that was compassionate and supportive, was positively related with the bond dimension of alliance. Clinical implications and future research directions regarding patient crying experiences in psychotherapy are discussed.

Why Elites Love Authentic Lowbrow Culture: Overcoming High-Status Denigration with Outsider Art

Why Elites Love Authentic Lowbrow Culture: Overcoming High-Status Denigration with Outsider Art. By Oliver Hahl, Ezra W. Zuckerman, Minjae Kim
American Sociological Review
http://journals.sagepub.com/doi/abs/10.1177/0003122417710642

Abstract: We develop and test the idea that public appreciation for authentic lowbrow culture affords an effective way for certain elites to address feelings of authenticity-insecurity arising from “high status denigration” (Hahl and Zuckerman 2014). This argument, which builds on recent sociological research on the “search for authenticity” (e.g., Grazian 2005) and on Bourdieu’s (1993) notion of artistic “disinterestedness,” is validated through experiments with U.S. subjects in the context of “outsider” art (Fine 2004). The first study demonstrates that preference for lowbrow culture perceived to be authentic is higher when individuals feel insecure in their authenticity because they attained status in a context where extrinsic incentives are salient. The second study demonstrates that audiences perceive the members of erstwhile denigrated high-status categories to be more authentic if they consume lowbrow culture, but only if the cultural producer is perceived as authentic. We conclude by noting how this “authenticity-by-appreciation” effect might be complementary to distinction-seeking as a motivation for elite cultural omnivorousness, and we draw broader implications for when and why particular forms of culture are in demand.

Mi resumen de lo que los autores defienden: el aprecio por el arte lowbrow* proporciona a ciertas élites un modo eficaz de abordar la inseguridad sobre su autenticidad, dudas que emanan del la denigración del status alto (“high status denigration,” Hahl and Zuckerman 2014). La búsqueda de la autenticidad y el carácter desinteresado, no enfocado en lo lucrativo, de ciertas muestras artísticas, se someten a experimentos con sujetos estadounidenses. El primer estudio muestra que la preferencia por cultura lowbrow percibida como auténtica es alta cuando los sujetos se sienten inseguros sobre su autenticidad. El segundo estudio muestra que los otros perciben a miembros de las categorias denigradas (alto standing) como más auténticos si consumen cultura lowbrow, pero solo si el productor cultural se percibe como auténtico. Este efecto de autenticidad es complementario a la búsqueda de carácter único en la motivación del carácter omnívoro cultural de la élite.

* lowbrow art: An underground visual art movement that arose in the Los Angeles area in the late 1970s. Lowbrow is a widespread populist art movement with origins in the underground comix world, punk music, hot-rod street culture, and other California subcultures. It is also often known by the name pop surrealism. Most lowbrow artworks are paintings, but there are also toys, and sculptures. Many of the creators of lowbrow art are influenced by Acid house flyers, Advertising, Animated cartoons, Circus and Sideshow culture, Commercial art, Comic books, Erotica, Graffiti and Street art, Kitsch, Kustom Kulture, Mail art, Pop culture, Psychedelic art, Punk rock culture, Retro Illustration, Religious art, Pulp magazine art, Surf culture, Tattoo art, Tiki culture, Toys for adults, notably vinyl figurines, anti-political views, among many other things.

Are the ethnically tolerant free of discrimination, prejudice and political intolerance? They aren't.

Bizumic, B., Kenny, A., Iyer, R., Tanuwira, J., and Huxley, E. (2017) Are the ethnically tolerant free of discrimination, prejudice and political intolerance? Eur. J. Soc. Psychol., doi: 10.1002/ejsp.2263
http://onlinelibrary.wiley.com/doi/10.1002/ejsp.2263/abstract

Abstract: We hypothesized that the ethnically tolerant (i.e., people who are anti-ethnocentric and score very low on a measure of ethnocentrism) would perceive people with extremely incompatible values and beliefs as out-groups and would engage in discrimination, prejudice and political intolerance against them. Experiments among Australian citizens in Studies 1 (N = 224) and 2 (N = 283) showed that the ethnically tolerant perceived supporters of a message in favour of mandatory detention of asylum seekers as out-groups and consequently exhibited discrimination, prejudice and political intolerance against them. Study 3 with 265 U.S. citizens showed that, controlling for liberalism, ethnic tolerance led to prejudice against out-groups. This was replicated with 522 UK citizens in Study 4, which also showed that social identity, and not moral conviction, mediated the link between ethnic tolerance and prejudice. The findings suggest that the ethnically tolerant can be discriminatory, prejudiced and politically intolerant against fellow humans.

The self and autobiographical memories of immoral actions

I’m not the person I used to be: The self and autobiographical memories of immoral actions. By Stanley, Matthew L.; Henne, Paul; Iyengar, Vijeth; Sinnott-Armstrong, Walter; De Brigard, Felipe
Journal of Experimental Psychology: General, Vol 146(6), Jun 2017, 884-895
http://dx.doi.org/10.1037/xge0000317

Abstract: People maintain a positive identity in at least two ways: They evaluate themselves more favorably than other people, and they judge themselves to be better now than they were in the past. Both strategies rely on autobiographical memories. The authors investigate the role of autobiographical memories of lying and emotional harm in maintaining a positive identity. For memories of lying to or emotionally harming others, participants judge their own actions as less morally wrong and less negative than those in which other people lied to or emotionally harmed them. Furthermore, people judge those actions that happened further in the past to be more morally wrong than those that happened more recently. Finally, for periods of the past when they believed that they were very different people than they are now, participants judge their actions to be more morally wrong and more negative than those actions from periods of their pasts when they believed that they were very similar to who they are now. The authors discuss these findings in relation to theories about the function of autobiographical memory and moral cognition in constructing and perceiving the self over time.

How much information to sample before making a decision? It's a matter of psychological distance

How much information to sample before making a decision? It's a matter of psychological distance. By Vered Halamish & Nira Liberman
Journal of Experimental Social Psychology, July 2017, Pages 111–116
http://www.sciencedirect.com/science/article/pii/S0022103116307089

Abstract:: When facing a decision, people look for relevant information to guide their choice. But how much information do they seek to obtain? Based on Construal Level Theory, we predicted that psychological distance from a decision would make participants seek more information prior to making a decision. Five experiments supported this prediction. When facing a decision between two decks of cards or two urns with marbles, participants preferred to sample more units of information for the purpose of making this decision in the distant future or for a friend (vs. in the near future or for themselves). These results suggest that expanding the scope of sampled experience is yet another way by which psychological distance affects decision making.

The Benefits of Forced Experimentation: Striking Evidence from the London Underground Network

The Benefits of Forced Experimentation: Striking Evidence from the London Underground Network. By Ferdinand Rauch, Shaun Larcom, Tim Willems
https://www.economics.ox.ac.uk/Department-of-Economics-Discussion-Paper-Series/the-benefits-of-forced-experimentation-striking-evidence-from-the-london-underground-network

Abstract: We estimate that a significant fraction of commuters on the London underground do not travel their optimal route. Consequently, a tube strike (which forced many commuters to experiment with new routes) taught commuters about the existence of superior journeys -- bringing about lasting changes in behaviour. This effect is stronger for commuters who live in areas where the tube map is more distorted, thereby pointing towards the importance of informational imperfections. We argue that the information produced by the strike improved network-efficiency. Search costs are unlikely to explain the suboptimal behaviour. Instead, individuals seem to under-experiment in normal times, as a result of which constraints can be welfare-improving.

Need for uniqueness motivates conspiracy beliefs

Imhoff, R., and Lamberty, P. K. (2017) Too special to be duped: Need for uniqueness motivates conspiracy beliefs. Eur. J. Soc. Psychol., doi: 10.1002/ejsp.2265
http://onlinelibrary.wiley.com/doi/10.1002/ejsp.2265/full

Abstract: Adding to the growing literature on the antecedents of conspiracy beliefs, this paper argues that a small part in motivating the endorsement of such seemingly irrational beliefs is the desire to stick out from the crowd, the need for uniqueness. Across three studies, we establish a modest but robust association between the self-attributed need for uniqueness and a general conspirational mindset (conspiracy mentality) as well as the endorsement of specific conspiracy beliefs. Following up on previous findings that people high in need for uniqueness resist majority and yield to minority influence, Study 3 experimentally shows that a fictitious conspiracy theory received more support by people high in conspiracy mentality when this theory was said to be supported by only a minority (vs. majority) of survey respondents. Together, these findings support the notion that conspiracy beliefs can be adopted as a means to attain a sense of uniqueness.

Perceived social presence reduces fact-checking

Perceived social presence reduces fact-checking. By Youjung Jun, Rachel Meng, and Gita Venkataramani Johar
Proceedings of the National Academy of Sciences    vol. 114 no. 23
DOI 10.1073/pnas.1700175114, http://www.pnas.org/content/114/23/5976.abstract

Significance: The dissemination of unverified content (e.g., “fake” news) is a societal problem with influence that can acquire tremendous reach when propagated through social networks. This article examines how evaluating information in a social context affects fact-checking behavior. Across eight experiments, people fact-checked less often when they evaluated claims in a collective (e.g., group or social media) compared with an individual setting. Inducing momentary vigilance increased the rate of fact-checking. These findings advance our understanding of whether and when people scrutinize information in social environments. In an era of rapid information diffusion, identifying the conditions under which people are less likely to verify the content that they consume is both conceptually important and practically relevant.

Abstract: Today’s media landscape affords people access to richer information than ever before, with many individuals opting to consume content through social channels rather than traditional news sources. Although people frequent social platforms for a variety of reasons, we understand little about the consequences of encountering new information in these contexts, particularly with respect to how content is scrutinized. This research tests how perceiving the presence of others (as on social media platforms) affects the way that individuals evaluate information—in particular, the extent to which they verify ambiguous claims. Eight experiments using incentivized real effort tasks found that people are less likely to fact-check statements when they feel that they are evaluating them in the presence of others compared with when they are evaluating them alone. Inducing vigilance immediately before evaluation increased fact-checking under social settings.

Call My Rep! How Unions Overcame the Free-Rider Problem

Murphy, Richard John: Call My Rep! How Unions Overcame the Free-Rider Problem (March 01, 2017). CESifo Working Paper Series No. 6362. Available at SSRN: https://ssrn.com/abstract=2941381

Abstract: This paper proposes an explanation of why union membership has been increasing in some occupations, despite the opportunity to freeride on traditional union benefits. I model membership as legal insurance whose demand increases with the perceived risk of allegations. Using media reports on allegations against teachers as shocks to perceived risk, I find for every five reports occurring in a region, teachers are 2.5 percentage points more likely to be members in the subsequent year. These effects are larger when teachers share characteristics with the news story and explain 45 percent of the growth in teacher union membership since 1992.

Increase in own state's minimum wage increases frequency with which low-wage workers commute out of the state

Cross-state differences in the minimum wage and out-of-state commuting by low-wage workers. By Terra McKinnish
Regional Science and Urban Economics, Volume 64, May 2017, Pages 137–147
https://doi.org/10.1016/j.regsciurbeco.2017.02.006
Highlights

•  The federal minimum wage hike compressed cross-border minimum wage differentials.
•  Low wage workers responded by commuting out of states that increased their minimum wage.
•  Results are consistent with a disemployment effect of minimum wage increases.

Abstract: The 2009 federal minimum wage increase, which compressed cross-state differences in the minimum wage, is used to investigate the claim that low-wage workers are attracted to commute out of state to neighboring states that have higher minimum wages. The analysis focuses on Public Use Microdata Areas (PUMAs) that experience commuting flows with one or more neighboring state. A difference-in-differences-in-differences model compares PUMAs that experienced a sizeable increase or decrease in their cross-border minimum wage differential to those that experience smaller change in the cross-border differential. Out-of-state commuting of low wage workers (less than 10 dollars an hour) is then compared to that of moderate wage workers (10–13 dollars an hour). The results suggest that an increase in own state's minimum wage, relative to neighbor's, increases the frequency with which low-wage workers commute out of the state. The analysis is replicated on the subset of PUMAs that experience commuting flows with more than one neighboring state, so that the estimates are identified entirely within PUMA. As a whole, the results suggest that low-wage workers tend to commute away from minimum wage increases rather than towards them.

Rethinking the Benefits of Youth Employment Programs: The Heterogeneous Effects of Summer Jobs

Rethinking the Benefits of Youth Employment Programs: The Heterogeneous Effects of Summer Jobs
Jonathan Davis & Sara Heller
NBER Working Paper, May 2017
http://www.nber.org/papers/w23443

Abstract: his paper reports the results of two randomized field experiments, each offering different populations of youth a supported summer job in Chicago. In both experiments, the program dramatically reduces violent-crime arrests, even after the summer. It does so without improving employment, schooling, or other types of crime; if anything, property crime increases over 2-3 post-program years. To explore mechanisms, we implement a machine learning method that predicts treatment heterogeneity using observables. The method identifies a subgroup of youth with positive employment impacts, whose characteristics differ from the disconnected youth served in most employment programs. We find that employment benefiters commit more property crime than their control counterparts, and non-benefiters also show a decline in violent crime. These results do not seem consistent with typical theory about improved human capital and better labor market opportunities creating a higher opportunity cost of crime, or even with the idea that these programs just keep youth busy. We discuss several alternative mechanisms, concluding that brief youth employment programs can generate substantively important behavioral change, but for different outcomes, different youth, and different reasons than those most often considered in the literature.

Increase in deployment & combat injuries for white and Hispanic soldiers relative to black ones & for soldiers from high-income neighborhoods relative to those from low-income ones

Who Will Fight? The All-Volunteer Army after 9/11. By Susan Payne Carter, Alexander Smith & Carl Wojtaszek
American Economic Review, May 2017, Pages 415-419
https://www.aeaweb.org/articles?id=10.1257/aer.p20171082

Abstract: Who fought the War on Terror? We find that as the wars in Iraq and Afghanistan progressed, there was an increase in the fraction of active-duty Army enlistees who were white or from high-income neighborhoods and that these two groups selected combat occupations more often. Among men, we find an increase in deployment and combat injuries for white and Hispanic soldiers relative to black soldiers and for soldiers from high-income neighborhoods relative to those from low-income neighborhoods. This finding suggests that an all-volunteer force does not compel a disproportionate number of non-white and low socio-economic men to fight America's wars.

IV.  Discussion
Today's all-volunteer force represents a diverse group of individuals serving for both patriotic and economic reasons. For those with fewer economic opportunities, a steady job may be the deciding factor in their enlistment decision; while for those with more outside options, wartime service may shape their deci- sion. Concerns over equity could arise under the  all-volunteer system if these enlistment motivations are differentially distributed across demographic groups. While we cannot uncover the distribution of these motivations, we can observe which groups bear the burden of war. Were the first sustained conflicts of the AVF.Iraq and Afghanistan..poor man.s fights.? To the contrary, during this time period it does not appear that there was an undue burden placed on blacks or individuals from low-income neighborhoods. The percentages of black and low-income enlistees decreased as fighting intensified, with these trends stopping when outside labor market opportunities diminished during the Great Recession and combat risk decreased. These trends were the same for men and women, although black women continued to be over-represented in the Army relative to the general population. Furthermore, black and low-income enlisted men were less likely than their white and high-income peers to be deployed or injured in combat. These differences are driven primarily by the military occupation an individual enters: black and low-income men were less likely to choose combat-intensive occupations than their white and high-income peers with the same eligibility.

Will the high-tech cities of the future be utterly lonely?

Will the high-tech cities of the future be utterly lonely? By Jessica Brown
The Week, April 24, 2017
http://theweek.com/articles/689527/hightech-cities-future-utterly-lonely

In Britain, more than one in eight people say they don't consider anyone a close friend, and the number of Americans who say they have no close friends has roughly tripled in recent decades. A large proportion of the lonely are young; almost two-thirds of 16- to 24-year-old Brits said they feel lonely at least some of the time, while almost a third are lonely often or all the time.


Healthy offspring from freeze-dried mouse spermatozoa held on the International Space Station for 9 months

Healthy offspring from freeze-dried mouse spermatozoa held on the International Space Station for 9 months. Sayaka Wakayama et al. Proceedings of the National Academy of Sciences, May 22 2017. http://www.pnas.org/content/early/2017/05/16/1701425114.full

Significance: Radiation on the International Space Station (ISS) is more than 100 times stronger than at the Earth’s surface, and at levels that can cause DNA damage in somatic cell nuclei. The damage to offspring caused by this irradiation in germ cells has not been examined, however. Here we preserved mouse spermatozoa on the ISS for 9 mo. Although sperm DNA was slightly damaged during space preservation, it could be repaired by the oocyte cytoplasm and did not impair the birth rate or normality of the offspring. Our results demonstrate that generating human or domestic animal offspring from space-preserved spermatozoa is a possibility, which should be useful when the “space age” arrives.

Abstract: If humans ever start to live permanently in space, assisted reproductive technology using preserved spermatozoa will be important for producing offspring; however, radiation on the International Space Station (ISS) is more than 100 times stronger than that on Earth, and irradiation causes DNA damage in cells and gametes. Here we examined the effect of space radiation on freeze-dried mouse spermatozoa held on the ISS for 9 mo at –95 °C, with launch and recovery at room temperature. DNA damage to the spermatozoa and male pronuclei was slightly increased, but the fertilization and birth rates were similar to those of controls. Next-generation sequencing showed only minor genomic differences between offspring derived from space-preserved spermatozoa and controls, and all offspring grew to adulthood and had normal fertility. Thus, we demonstrate that although space radiation can damage sperm DNA, it does not affect the production of viable offspring after at least 9 mo of storage on the ISS.

Distress disclosure, depression, life satisfaction, and cultural differences

Distress disclosure and psychological functioning among Taiwanese nationals and European Americans: The moderating roles of mindfulness and nationality.
Kahn, Jeffrey H.; Wei, Meifen; Su, Jenny C.; Han, Suejung; Strojewska, Agnes
Journal of Counseling Psychology, Vol 64(3), Apr 2017, 292-301. http://dx.doi.org/10.1037/cou0000202

Abstract: Research using Western samples shows that talking about unpleasant emotions—distress disclosure—is associated with fewer psychological symptoms and higher well-being. These benefits of distress disclosure may or may not be observed in East Asia where emotional control is valued. Instead, mindfulness may be more relevant to emotion regulation in East Asia (e.g., Taiwan). In the present study, cultural context (Taiwanese nationals vs. European Americans) and mindfulness were examined as moderators of the relation between distress disclosure and both depression symptoms and life satisfaction. A sample of 256 Taiwanese college students and a sample of 209 European American college students completed self-report measures in their native language. Moderated multiple regression analyses revealed significant interaction effects of mindfulness and distress disclosure on both depression symptoms and life satisfaction for Taiwanese participants but not for European Americans. Specifically, distress disclosure was negatively associated with depression symptoms and positively associated with life satisfaction for Taiwanese low in mindfulness but not for Taiwanese high in mindfulness. For European Americans, distress disclosure was not associated with depression symptoms but was associated with higher life satisfaction, regardless of one’s level of mindfulness. These findings suggest that the potential benefits of disclosing distress are a function of one’s cultural context as well as, for those from Taiwan, one’s mindfulness.

Unintended Consequences: The Regressive Effects of Increased Access to Courts

Unintended Consequences: The Regressive Effects of Increased Access to Courts. By Anthony  Niblett & Albert  Yoon, University of Toronto - Faculty of Law
Small claims courts enable parties to resolve their disputes relatively quickly and cheaply. The court’s limiting feature, by design, is that alleged damages must be small, in accordance with the jurisdictional limit at that time. Accordingly, one might expect that a large increase in the upper limit of claim size would increase the court’s accessibility to a larger and potentially more diverse pool of litigants.

We examine this proposition by studying the effect of an increase in the jurisdictional limit of the Ontario Small Claims Court. Prior to January 2010, claims up to $10,000 could be litigated in the small claims court. After January 2010, this jurisdictional limit increased to include all claims up to $25,000. We study patterns in nearly 625,000 disputes over the period 2006-2013.

In this paper, we investigate plaintiff behavior. Interestingly, the total number of claims filed by plaintiffs does not increase significantly with the increased jurisdictional limit. We do find, however, changes to the composition of plaintiffs. Following the jurisdictional change, we find that plaintiffs using the small claims court are, on average, from richer neighborhoods. We also find that proportion of plaintiffs from poorer neighborhoods drops. The drop-off is most pronounced in plaintiffs from the poorest 10% of neighborhoods.

We explore potential explanations for this regressive effect, including crowding out, congestion, increased legal representation, and behavioral influences. Our findings suggest that legislative attempts to make the courts more accessible may have unintended regressive consequences.

From Existential to Social Understandings of Risk - Examining Gender Differences in Nonreligion

From Existential to Social Understandings of Risk - Examining Gender Differences in Nonreligion. By Penny Edgell, Jacqui Frost, Evan Stewart

Abstract: Across many social contexts, women are found to be more religious than men. Risk preference theory proposes that women are less likely than men to accept the existential risks associated with nonbelief. Building on previous critiques of this theory, we argue that the idea of risk is relevant to understanding the relationship between gender and religiosity if risk is understood not as existential, but as social. The research on existential risk focuses on religious identification as solely a matter of belief; as part of the movement away from this cognitivist bias, we develop the concept of social risk to theorize the ways that social location and differential levels of power and privilege influence women’s nonreligious choices. We show that women’s nonreligious preferences in many ways mirror those of other marginalized groups, including nonwhites and the less educated. We argue that nonreligion is socially risky, that atheism is more socially risky than other forms of nonreligion, and that women and members of other marginalized groups avoid the most socially risky forms of nonreligion.

When Children Rule: Parenting in Modern Families

During the 20th century there was a secular transformation within American families from a household dominated by the father to a more egalitarian one in which the wife and the children have been empowered. This transformation coincided with two major economic and demographic changes, namely the increase in economic opportunities for women and a decline in family size. To explain the connection between these trends and the transformation in family relationships we develop a novel model of parenting styles that highlights the importance of competition within the family. The key intuition is that the rise in relative earnings of wives increased competition between spouses for the love and affection of their children while the decline in family size reduced competition between children for resources from their parents. The combined effect has empowered children within the household and allowed them to capture an increasing share of the household surplus over the past hundred years

Pregnancy leads to long-lasting changes in human brain structure

Abstract: Pregnancy involves radical hormone surges and biological adaptations. However, the effects of pregnancy on the human brain are virtually unknown. Here we show, using a prospective ('pre'-'post' pregnancy) study involving first-time mothers and fathers and nulliparous control groups, that pregnancy renders substantial changes in brain structure, primarily reductions in gray matter (GM) volume in regions subserving social cognition. The changes were selective for the mothers and highly consistent, correctly classifying all women as having undergone pregnancy or not in-between sessions. Interestingly, the volume reductions showed a substantial overlap with brain regions responding to the women's babies postpartum. Furthermore, the GM volume changes of pregnancy predicted measures of postpartum maternal attachment, suggestive of an adaptive process serving the transition into motherhood. Another follow-up session showed that the GM reductions endured for at least 2 years post-pregnancy. Our data provide the first evidence that pregnancy confers long-lasting changes in a woman's brain.

A Virtual Out-of-Body Experience Reduces Fear of Death

A Virtual Out-of-Body Experience Reduces Fear of Death. By Pierre Bourdin et al.

Abstract: Immersive virtual reality can be used to visually substitute a person’s real body by a life-sized virtual body (VB) that is seen from first person perspective. Using real-time motion capture the VB can be programmed to move synchronously with the real body (visuomotor synchrony), and also virtual objects seen to strike the VB can be felt through corresponding vibrotactile stimulation on the actual body (visuotactile synchrony). This setup typically gives rise to a strong perceptual illusion of ownership over the VB. When the viewpoint is lifted up and out of the VB so that it is seen below this may result in an out-of-body experience (OBE). In a two-factor between-groups experiment with 16 female participants per group we tested how fear of death might be influenced by two different methods for producing an OBE. In an initial embodiment phase where both groups experienced the same multisensory stimuli there was a strong feeling of body ownership. Then the viewpoint was lifted up and behind the VB. In the experimental group once the viewpoint was out of the VB there was no further connection with it (no visuomotor or visuotactile synchrony). In a control condition, although the viewpoint was in the identical place as in the experimental group, visuomotor and visuotactile synchrony continued. While both groups reported high scores on a question about their OBE illusion, the experimental group had a greater feeling of disownership towards the VB below compared to the control group, in line with previous findings. Fear of death in the experimental group was found to be lower than in the control group. This is in line with previous reports that naturally occurring OBEs are often associated with enhanced belief in life after death.
