Trumped by context collapse: Examination of ‘Liking’ political candidates in the presence of audience diversity. Ben Marder. Computers in Human Behavior, https://doi.org/10.1016/j.chb.2017.10.025
Highlights
• Examination of the effect of audience diversity on ‘Liking’ political candidates.
• Survey of 1027 potential voters prior the 2016 US presidential election.
• Increased audience diversity is associated with a reduced ‘Liking’.
• Increased audience diversity predicts greater social anxiety.
• ‘Non-Likers’ have a more diverse audience than ‘Likers’.
Abstract: Harnessing social media such as Facebook is now considered critical for electoral success. Although Facebook is widely used by the electorate, few have ‘Liked’ the Facebook pages of the political candidates for whom they vote. To provide understanding of this discrepancy, the present paper offers the first investigation on the role of audience diversity on ‘Liking’ behavior, as well as its association with varying degrees of social anxiety that may arise from ‘Liking’ political candidates. A survey of potential voters who used Facebook preceding the 2016 Presidential Election was conducted ( = 1027). Using the lens of Self-Presentation Theory, results found that for those who had not already ‘Liked’ Hillary Clinton or Donald Trump, their intention to do so before the election was negatively associated with the diversity of their Facebook audience. This relationship was mediated by their expected degree of social anxiety from ‘Liking’ the candidate. A comparison of audience diversity of participants who had ‘Liked’ a candidate vs. those who had not ‘Liked’ a candidate also showed that increased audience diversity hinders ‘Liking’. This paper contributes to the knowledge of engagement with politicians through social media as well as the study of audience diversity more generally. Implications for managers are provided.

Psychedelic use associated with reduced odds of larceny/theft, assault, arrest for a property crime & for a violent crime
The relationships of classic psychedelic use with criminal behavior in the United States adult population. Peter S Hendricks et al. Journal of Psychopharmacology, https://doi.org/10.1177/0269881117735685
Abstract: Criminal behavior exacts a large toll on society and is resistant to intervention. Some evidence suggests classic psychedelics may inhibit criminal behavior, but the extent of these effects has not been comprehensively explored. In this study, we tested the relationships of classic psychedelic use and psilocybin use per se with criminal behavior among over 480,000 United States adult respondents pooled from the last 13 available years of the National Survey on Drug Use and Health (2002 through 2014) while controlling for numerous covariates. Lifetime classic psychedelic use was associated with a reduced odds of past year larceny/theft (aOR = 0.73 (0.65–0.83)), past year assault (aOR = 0.88 (0.80–0.97)), past year arrest for a property crime (aOR = 0.78 (0.65–0.95)), and past year arrest for a violent crime (aOR = 0.82 (0.70–0.97)). In contrast, lifetime illicit use of other drugs was, by and large, associated with an increased odds of these outcomes. Lifetime classic psychedelic use, like lifetime illicit use of almost all other substances, was associated with an increased odds of past year drug distribution. Results were consistent with a protective effect of psilocybin for antisocial criminal behavior. These findings contribute to a compelling rationale for the initiation of clinical research with classic psychedelics, including psilocybin, in forensic settings.

How Will China's Industrial Modernization Plan affect Workers? By Boy Luethje
How Will China's Industrial Modernization Plan affect Workers? By Boy Luethje. East-West Center, Oct 17 2017. How Will China’s Industrial Modernization Plan Affect Workers? | East-West Center | www.eastwestcenter.org
HONOLULU (Oct. 17, 2017) -- Today’s discussions about the future of manufacturing are awash with visions of revolutionary change. Digital technologies are expected to create a “fourth industrial revolution”—a world of seamlessly interconnected “smart factories” driven by artificial intelligence, cloud computing and big data applications.
In line with this thinking, China has developed a master plan to transform its vast manufacturing base from low-cost export production to highly automated advanced manufacturing aimed primarily at the domestic market. The plan was drafted by the Ministry of Industry and Information Technology (MIIT) and was outlined in 2015 in a comprehensive government document titled “Made in China 2025.”
Made in China 2025 gives a strong role to China’s new multinationals in areas such as solar systems, wind turbines, LED, household appliances and, most prominently, telecommunications and advanced Internet services. The plan thus reflects the increased importance of large non-state-owned enterprises as drivers of innovation and marks a substantial change in economic power relations in China.
Serious questions remain, however, for China’s large, low-wage labor force, particularly related to labor markets, the transformation of work and industrial relations. Reforms are needed in areas such as vocational training, human-resource management, wage and incentive systems, appraisal of skills, and workplace safety and privacy. Yet the Ministry of Labor and Social Security, the Ministry of Education, the All China Federation of Trade Unions and other mass organizations have been mostly absent from the drafting and execution of the program.
Some relevant labor laws have been extended in recent years and offer improved protections for workers related to mass layoffs, workplace safety and employment of temporary workers. Current discussions are dominated, however, by demands to discontinue key provisions of the 2008 Labor Contract Law in order to facilitate the massive job reductions underway in state-owned heavy industries and coal mining.
Meanwhile, the Chinese government and research institutions have not provided any valid assessment of the potential labor-market effects of Made in China 2025. The relevant statistics are scattered among various government agencies, making it difficult to assess the labor-market, social-security, training and other implications of the program. Ongoing research on current automation projects and policies clearly indicates that massive job cuts lie ahead. The effect will vary by industry and region:
. In predominantly state-owned manufacturing, such as the automotive industry, the job impacts of digitalization appear to be relatively minor. Many factories are already characterized by high levels of automation, and digital technologies can be introduced gradually.
. Among private Chinese and multinational manufacturers with large, low-wage labor forces, the effects of transformation from labor-intensive to automated manufacturing are potentially much greater. In some model “Internet factories” of home-appliance makers, more than 50 percent of the manufacturing workforce has already been cut.
. Job reductions are potentially highest among labor-intensive small and medium enterprises. Here, relatively simple automation equipment can replace large numbers of semi- and low-skilled workers. A recent study in the city of Dongguan in central Guangdong Province found job reductions of 67 to 85 percent in such companies, often affecting the workers with the best skills and bargaining positions.
The situation in Guangdong Province illustrates the negative effects of top-down industrial policies. Ambitious to become China’s leading region in factory automation, the provincial government has promoted Made in China 2025 with the slogan “Robot-Replaces-Man.” City governments have picked up the message and make the replacement of workers a top criterion in their plans to subsidize the procurement of robots. The issue of job cuts and retraining is mostly ignored because many of the workers who lose their jobs are migrants from other regions.
The Dongguan city government reported that in 2015, the first year of its “Robot-Replaces-Man” program, 1,262 participating companies cut 71,000 jobs. With a working population of more than five million, the local labor market may absorb these job losses for the time being. In the long term, however, serious problems may occur.
Overall, digital technologies have significant potential to change the structure of manufacturing, improve cooperation within production networks and relocate production closer to end markets. For China, digital manufacturing could ease pressures for large-scale urbanization and related problems of labor migration.
Instead of the present top-down approach, industrial policies “from below” could integrate technological upgrading with strategies to develop a skilled workforce and rebalance labor markets. Industrial cities in the Pearl River Delta, for example, could support industrial upgrading by making subsidies for automation equipment conditional upon improvements in working conditions and training of workers. Long-term development of a skilled industrial workforce could be supported by granting permanent residence (called hukou) to migrant workers who graduate from vocational training programs. Last but not least, the provincial and local trade unions could enforce standards of decent work and accelerate the implementation of collective bargaining in privately owned enterprises.
Such approaches exist, but the innovative potential of digital manufacturing to improve conditions for China’s huge workforce remains unexplored due to pressure for short-term profits and the absence of institutional reform. There will most likely be job losses, but the key challenge is to find the right mix of automation and a higher-skilled labor force for long-term growth.

After seeing an agent attain two goals equally often at varying costs, infants expected the agent to prefer the goal it attained through costlier actions
Liu, Shari, Tomer D Ullman, josh tenenbaum, and Elizabeth Spelke. 2017. “Ten-month-old Infants Infer the Value of Goals from the Costs of Actions”. PsyArXiv. October 17. psyarxiv.com/78qd4
Abstract: Infants understand that people pursue goals, but how do they learn which goals people prefer? Here, we test whether infants solve this problem by inverting a mental model of action planning, trading off the costs of acting against the rewards actions bring. After seeing an agent attain two goals equally often at varying costs, infants expected the agent to prefer the goal it attained through costlier actions. These expectations held across three experiments conveying cost through different physical path features (jump height and width; incline angle), suggesting that an abstract variable, such as ‘force’, ‘work’ or ‘effort’, supported infants’ inferences. We model infants' expectations as Bayesian inferences over utility-theoretic calculations, providing a bridge to recent quantitative accounts of action understanding in older children and adults.

Dramatic pretend play games uniquely improve emotional control in young children
Goldstein TR, Lerner MD. Dramatic pretend play games uniquely improve emotional control in young children. Dev Sci. 2017;e12603. https://doi.org/10.1111/desc.12603
Abstract: Pretense is a naturally occurring, apparently universal activity for typically developing children. Yet its function and effects remain unclear. One theorized possibility is that pretense activities, such as dramatic pretend play games, are a possible causal path to improve children's emotional development. Social and emotional skills, particularly emotional control, are critically important for social development, as well as academic performance and later life success. However, the study of such approaches has been criticized for potential bias and lack of rigor, precluding the ability to make strong causal claims. We conducted a randomized, component control (dismantling) trial of dramatic pretend play games with a low-SES group of 4-year-old children (N = 97) to test whether such practice yields generalized improvements in multiple social and emotional outcomes. We found specific effects of dramatic play games only on emotional self-control. Results suggest that dramatic pretend play games involving physicalizing emotional states and traits, pretending to be animals and human characters, and engaging in pretend scenarios in a small group may improve children's emotional control. These findings have implications for the function of pretense and design of interventions to improve emotional control in typical and atypical populations. Further, they provide support for the unique role of dramatic pretend play games for young children, particularly those from low-income backgrounds.

Generic language encourages to categorize individuals using a lower evidentiary standard regardless of negative consequences
When Your Kind Cannot Live Here: How Generic Language and Criminal Sanctions Shape Social Categorization. Deborah Goldfarb et al. Psychological Science, https://doi.org/10.1177/0956797617714827
Abstract: Using generic language to describe groups (applying characteristics to entire categories) is ubiquitous and affects how children and adults categorize other people. Five-year-olds, 8-year-olds, and adults (N = 190) learned about a novel social group that separated into two factions (citizens and noncitizens). Noncitizens were described in either generic or specific language. Later, the children and adults categorized individuals in two contexts: criminal (individuals labeled as noncitizens faced jail and deportation) and noncriminal (labeling had no consequences). Language genericity influenced decision making. Participants in the specific-language condition, but not those in the generic-language condition, reduced the rate at which they identified potential noncitizens when their judgments resulted in criminal penalties compared with when their judgments had no consequences. In addition, learning about noncitizens in specific language (vs. generic language) increased the amount of matching evidence participants needed to identify potential noncitizens (preponderance standard) and decreased participants’ certainty in their judgments. Thus, generic language encourages children and adults to categorize individuals using a lower evidentiary standard regardless of negative consequences for presumed social-group membership.

Typical courses and critical thinking skills acquired during a semester are not sufficient to prompt skepticism about myth statements
Class Dis-Mythed: Exploring the Prevalence and Perseverance of Myths in Upper-Level Psychology Courses. Michael Root and Caroline Stanley. https://www.researchgate.net/publication/317646288_Class_Dis-Mythed_Exploring_the_Prevalence_and_Perseverance_of_Myths_in_Upper-Level_Psychology_Courses
Description: Undergraduates (N = 117) from two mid-sized universities enrolled in one of three psychology courses (Cognitive Psychology, Learning & Memory, or Personality) completed surveys about commonly held psychology myths related to the course in which they were enrolled. Students completed the surveys at the beginning and end of the semester. The purpose of our study was twofold. First, we wanted to measure the prevalence of myth beliefs in undergraduates taking upper level psychology courses. Second, we wanted to discern whether course content alone (i.e., readings, lectures, class activities, tests, and assignments) was sufficient to disabuse undergraduates of their myth beliefs. Although all three courses had prerequisite psychology courses, beginning-of-semester responses indicated that students in all three classes believed a majority of the myths related to the subject matter of their course. End-of-semester responses indicated that, unless a myth was explicitly debunked in a course (e.g., material in a Learning & Memory course contradicted their belief that people have different learning styles), myth beliefs persisted throughout the semester. Our results suggest that typical course content and any critical thinking skills acquired during a semester is not sufficient to prompt skepticism about myth statements. Instead, we argue that a more effective strategy to dispel common myths that may hinder undergraduates reasoning and critical thinking skills is for instructors to make undergraduates explicitly aware of these myths and how research fails to support them.

The Influence of Circadian Timing on Olfactory Sensitivity. Rachel S Herz, Eliza Van Reen, David Barker, Cassie J Hilditch, Ashten Bartz, Mary A Carskadon. Chemical Senses, bjx067, https://doi.org/10.1093/chemse/bjx067
Abstract: Olfactory sensitivity has traditionally been viewed as a trait that varies according to individual differences but is not expected to change with one’s momentary state. Recent research has begun to challenge this position and time of day has been shown to alter detection levels. Links between obesity and the timing of food intake further raise the issue of whether odor detection may vary as a function of circadian processes. To investigate this question, thirty-seven (21 male) adolescents (M age =13.7 years) took part in a 28-hr forced-desynchrony (FD) protocol with 17.5 hours awake and 10.5 hours of sleep, for seven FD cycles. Odor threshold was measured using Sniffin’ Sticks six times for each FD cycle (total threshold tests = 42). Circadian phase was determined by intrinsic period derived from dim light melatonin onsets. Odor threshold showed a significant effect of circadian phase, with lowest threshold occurring on average slightly after the onset of melatonin production, or about 1.5 ○ (approximately 21:08 hours). Considerable individual variability was observed, however, peak olfactory acuity never occurred between 80.5 ○- 197.5 ○ (~02:22-10:10 hours). These data are the first to show that odor threshold is differentially and consistently influenced by circadian timing, and is not a stable trait. Potential biological relevance for connections between circadian phase and olfactory sensitivity are discussed.

Citizens believe others, especially their political rivals, gravitate toward like-minded news
Public Perceptions of Partisan Selective Exposure. Perryman, Mallory R. The University of Wisconsin - Madison, ProQuest Dissertations Publishing, 2017. 10607943. https://search.proquest.com/openview/20d6e3befcf61455779aebe39b91d29f/1?pq-origsite=gscholar&cbl=18750&diss=y
From the introduction:
This dissertation investigates citizens’ perceptions of where others turn to for news, i.e., perceived exposure. In two empirical studies, I demonstrate how the assumptions that perceivers make about media and the assumptions they make about other people ultimately produce a perception of perceived partisan selective exposure. I test the extent to which citizens believe that they and others engage in selective media habits and examine the cognitive shortcuts that perceivers use to make such assessments. Ultimately, this investigation concludes that citizens believe others, especially their political rivals, gravitate toward like-minded news.
Though this is the first examination of public perceptions of selective exposure, it is not the first study to try and gauge perceptions of others’ media use. Capturing beliefs about others’ media exposure originated with research into perceived media effects, an avenue of research concerned with the ways in which people believe media impact other people. It is easy to see how perceived exposure is a core tenet of perceived media effects research: In order to believe others have been affected by a media message, a perceiver must first assume the others-in-question have been exposed to that message.
Understanding why citizens believe certain others interact with certain media messages thus requires revisiting the basic principles of perceived media effect research –- research that explores how individuals make assumptions other people, about media, and about what happens when other people encounter that media.

From the introduction:
This dissertation investigates citizens’ perceptions of where others turn to for news, i.e., perceived exposure. In two empirical studies, I demonstrate how the assumptions that perceivers make about media and the assumptions they make about other people ultimately produce a perception of perceived partisan selective exposure. I test the extent to which citizens believe that they and others engage in selective media habits and examine the cognitive shortcuts that perceivers use to make such assessments. Ultimately, this investigation concludes that citizens believe others, especially their political rivals, gravitate toward like-minded news.
Though this is the first examination of public perceptions of selective exposure, it is not the first study to try and gauge perceptions of others’ media use. Capturing beliefs about others’ media exposure originated with research into perceived media effects, an avenue of research concerned with the ways in which people believe media impact other people. It is easy to see how perceived exposure is a core tenet of perceived media effects research: In order to believe others have been affected by a media message, a perceiver must first assume the others-in-question have been exposed to that message.
Understanding why citizens believe certain others interact with certain media messages thus requires revisiting the basic principles of perceived media effect research –- research that explores how individuals make assumptions other people, about media, and about what happens when other people encounter that media.

Psychopaths are willing and able to disclose how they are under conditions of confidentiality, and do not mind being so
Kelley, S. E., Edens, J. F., Donnellan, M. B., Mowle, E. N. and Sörman, K. (), Self- and Informant Perceptions of Psychopathic Traits in Relation to the Triarchic Model. Journal of Personality. Accepted Author Manuscript. doi:10.1111/jopy.12354
Abstract
Objective: The validity of self-report psychopathy measures may be undermined by characteristics thought to be defining features of the construct, including poor self-awareness, pathological lying, and impression management. The current study examined agreement between self- and informant perceptions of psychopathic traits captured by the triarchic model (Patrick, Fowler, & Krueger, 2009) and the extent to which psychopathic traits are associated with socially desirable responding.
Method: Participants were undergraduate roommate dyads (N = 174; Mage = 18.9 years; 64.4% female; 59.8% Caucasian) who completed self- and informant-reports of boldness, meanness, and disinhibition.
Results: Self-reports of psychopathic traits reasonably aligned with the perceptions of informants (rs = .36 - .60) and both predicted various types of antisocial behaviors, although some associations were only significant for monomethod correlations. Participants viewed by informants as more globally psychopathic did not engage in greater positive impression management. However, this response style significantly correlated with self- and informant-reported boldness, suppressing associations with antisocial behavior.
Conclusions: These findings suggest that participants are willing and able to disclose psychopathic personality traits in research settings under conditions of confidentiality. Nonetheless, accounting for response style is potentially useful when using self-report measures to examine the nature and correlates of psychopathic traits.

Higher paternal age at offspring conception increases de novo genetic mutations & the children would be less likely to survive and reproduce
Older fathers' children have lower evolutionary fitness across four centuries and in four populations. Ruben Arslan et al. Proceedings of the Royal Society: Biological Sciences, Volume 284, issue 1862, September 13 2017. DO 10.1098/rspb.2017.1562
Abstract: Higher paternal age at offspring conception increases de novo genetic mutations. Based on evolutionary genetic theory we predicted older fathers' children, all else equal, would be less likely to survive and reproduce, i.e. have lower fitness. In sibling control studies, we find support for negative paternal age effects on offspring survival and reproductive success across four large populations with an aggregate N > 1.4 million. Three populations were pre-industrial (1670–1850) Western populations and showed negative paternal age effects on infant survival and offspring reproductive success. In twentieth-century Sweden, we found minuscule paternal age effects on survival, but found negative effects on reproductive success. Effects survived tests for key competing explanations, including maternal age and parental loss, but effects varied widely over different plausible model specifications and some competing explanations such as diminishing paternal investment and epigenetic mutations could not be tested. We can use our findings to aid in predicting the effect increasingly older parents in today's society will have on their children's survival and reproductive success. To the extent that we succeeded in isolating a mutation-driven effect of paternal age, our results can be understood to show that de novo mutations reduce offspring fitness across populations and time periods.

Menarcheal timing is accelerated by favorable nutrition but unrelated to developmental cues of mortality or familial instability
Menarcheal timing is accelerated by favorable nutrition but unrelated to developmental cues of mortality or familial instability in Cebu, Philippines. Moira A. Kyweluka et al. Evolution and Human Behavior, https://doi.org/10.1016/j.evolhumbehav.2017.10.002
Abstract: Understanding the determinants of pubertal timing, particularly menarche in girls, is an important area of investigation owing to the many health, psychosocial, and demographic outcomes related to reproductive maturation. Traditional explanations emphasized the role of favorable nutrition in maturational acceleration. More recently, work has documented early maturity in relation to markers of familial and environmental instability (e.g. paternal absence), which are hypothesized to serve as cues triggering adaptive adjustment of life history scheduling. While these studies hint at an ability of human females to accelerate maturity in stressful environments, most have focused on populations characterized by energetic excess. The present study investigates the role of developmental nutrition alongside cues of environmental risk and instability (maternal absence, paternal absence, and sibling death) as predictors of menarcheal age in a well-characterized birth cohort born in 1983 in metropolitan Cebu, the Philippines. In this sample, which was marked by a near-absence of childhood overweight and obesity, we find that menarcheal age is not predicted by cues of risk and instability measured at birth, during childhood and early adolescence, but that infancy weight gain and measures of favorable childhood nutrition are strong predictors of maturational acceleration. These findings contrast with studies of populations in which psychosocial stress and instability co-occur with excess weight. The present findings suggest that infancy and childhood nutrition may exert greater influence on age at menarche than psychosocial cues in environments characterized by marginal nutrition, and that puberty is often delayed, rather than accelerated, in the context of stressful environments.

Automated Driving: Use With Caution
Automated driving: Safety blind spots. Ian Y. Noy, David Shinar, William J. Horrey. Safety Science, Volume 102, February 2018, Pages 68–78. https://doi.org/10.1016/j.ssci.2017.07.018
Highlights
• Automated driving has the potential to improve traffic safety in the long term.
• For the foreseeable future, partially AD present unwitting consequences.
• Drivers’ role will change and lead to potential confusion or traffic conflicts.
• Human factors research is needed address new questions of partial automation.
• Integration within the broader cyber-physical world is an emerging challenge.
• This paper identifies areas that require explicit and urgent scientific exploration.
Abstract: Driver assist technologies have reached the tipping point and are poised to take control of most, if not all, aspects of the driving task. Proponents of automated driving (AD) are enthusiastic about its promise to transform mobility and realize impressive societal benefits. This paper is an attempt to carefully examine the potential of AD to realize safety benefits, to challenge widely-held assumptions and to delve more deeply into the barriers that are hitherto largely overlooked. As automated vehicle (AV) technologies advance and emerge within a ubiquitous cyber-physical world they raise additional issues that have not yet been adequately defined, let alone researched. Issues around automation, sociotechnical complexity and systems resilience are well known in the context of aviation and space. There are important lessons that could be drawn from these applications to help inform the development of automated driving. This paper argues that for the foreseeable future, regardless of the level of automation, a driver will continue to have a role. It seems clear that the benefits of automated driving, safety and otherwise, will accrue only if these technologies are designed in accordance with sound cybernetics principles, promote effective human-systems integration and gain the trust by operators and the public.
