Stimulus selectivity of drug purchase tasks: A preliminary study evaluating alcohol and cigarette demand

Stimulus selectivity of drug purchase tasks: A preliminary study evaluating alcohol and cigarette demand. By Strickland, Justin C.; Stoops, William W. Experimental and Clinical Psychopharmacology, Vol 25(3), Jun 2017, 198-207. http://dx.doi.org/10.1037/pha0000123

Abstract: The use of drug purchase tasks to measure drug demand in human behavioral pharmacology and addiction research has proliferated in recent years. Few studies have systematically evaluated the stimulus selectivity of drug purchase tasks to demonstrate that demand metrics are specific to valuation of or demand for the commodity under study. Stimulus selectivity is broadly defined for this purpose as a condition under which a specific stimulus input or target (e.g., alcohol, cigarettes) is the primary determinant of behavior (e.g., demand). The overall goal of the present study was to evaluate the stimulus selectivity of drug purchase tasks. Participants were sampled from the Amazon.com’s crowdsourcing platform Mechanical Turk. Participants completed either alcohol and soda purchase tasks (Experiment 1; N = 139) or cigarette and chocolate purchase tasks (Experiment 2; N = 46), and demand metrics were compared to self-reported use behaviors. Demand metrics for alcohol and soda were closely associated with commodity-similar (e.g., alcohol demand and weekly alcohol use) but not commodity-different (e.g., alcohol demand and weekly soda use) variables. A similar pattern was observed for cigarette and chocolate demand, but selectivity was not as consistent as for alcohol and soda. Collectively, we observed robust selectivity for alcohol and soda purchase tasks and modest selectivity for cigarette and chocolate purchase tasks. These preliminary outcomes suggest that demand metrics adequately reflect the specific commodity under study and support the continued use of purchase tasks in substance use research

Using Appellate Decisions to Evaluate the Impact of Judicial Elections

Using Appellate Decisions to Evaluate the Impact of Judicial Elections. By Gregory DeAngelo & Bryan McCannon
West Virginia University Working Paper, June 2017, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2973369

Abstract: We investigate judicial election's impact on criminal case handling. Data from appeals of felony convictions in New York state are used to measure the accuracy of lower court outcomes. We also account for judicial election pressures and career paths. A theoretical model is developed where to guide the empirical analysis judges face a trade-off between exerting time and effort in criminal and civil cases. We show that during a re-election campaign, when the importance of good decision making in both types of cases is heightened, if the civil case outcomes are sufficiently more important, then error rates in criminal cases can increase. This effect is reversed for those who have a greater intrinsic interest in criminal justice. Results from the empirical analysis conform to the hypotheses derived from the theoretical model. Convictions that occur during the judge's re-election campaign are less likely to be upheld if appealed. The effect is concentrated in those who did not previously work in a prosecutor's office. In fact, judges who are former prosecutors experience higher affirmation rates with an additional escalation in success when up for re-election. We also differentiate judges who handle more civil cases and show that re-election distortions are greater. Finally, we also consider those who receive greater campaign support from special interest groups. Those who receive financial support have reduced accuracy. These additional results are consistent with the theory that it is the trade-off between criminal and civil cases that is driving decision making. Our results suggest that the criminal justice system is impacted by the interaction between a judge's characteristics and re-election incentives.

Effects of alcohol, initial gambling outcomes, impulsivity, and gambling cognitions on gambling behavior using a video poker task

Effects of alcohol, initial gambling outcomes, impulsivity, and gambling cognitions on gambling behavior using a video poker task. By Corbin, William R.; Cronce, Jessica M.
Experimental and Clinical Psychopharmacology, Vol 25(3), Jun 2017, 175-185. http://dx.doi.org/10.1037/pha0000125

Abstract: Drinking and gambling frequently co-occur, and concurrent gambling and drinking may lead to greater negative consequences than either behavior alone. Building on prior research on the effects of alcohol, initial gambling outcomes, impulsivity, and gambling cognitions on gambling behaviors using a chance-based (nonstrategic) slot-machine task, the current study explored the impact of these factors on a skill-based (strategic) video poker task. We anticipated larger average bets and greater gambling persistence under alcohol relative to placebo, and expected alcohol effects to be moderated by initial gambling outcomes, impulsivity, and gambling cognitions. Participants (N = 162; 25.9% female) were randomly assigned to alcohol (target BrAC = .08g%) or placebo and were given $10 to wager on a simulated video poker task, which was programmed to produce 1 of 3 initial outcomes (win, breakeven, or lose) before beginning a progressive loss schedule. Despite evidence for validity of the video poker task and alcohol administration paradigm, primary hypotheses were not supported. Individuals who received alcohol placed smaller wagers than participants in the placebo condition, though this effect was not statistically significant, and the direction of effects was reversed in at-risk gamblers (n = 41). These findings contradict prior research and suggest that alcohol effects on gambling behavior may differ by gambling type (nonstrategic vs. strategic games). Interventions that suggest alcohol is universally disinhibiting may be at odds with young adults’ lived experience and thus be less effective than those that recognize the greater complexity of alcohol effects.

Far from fairness: Prejudice, skin color, and psychological functioning in Asian Americans

Far from fairness: Prejudice, skin color, and psychological functioning in Asian Americans. By Tran, Alisia G. T. T.; Cheng, Hsiu-Lan; Netland, Jason D.; Miyake, Elisa R.
Cultural Diversity and Ethnic Minority Psychology, Vol 23(3), Jul 2017, 407-415.
http://dx.doi.org/10.1037/cdp0000128

Abstract

Objectives: We explored the moderating role of observed skin color in the association between prejudice and concurrent and lagged psychological functioning (i.e., depression, ingroup/outgroup psychological connectedness). We further aimed to understand gender differences in these processes.

Method: Data from 821 Asian American undergraduate students (57.5% female and 42.5% male) were drawn from the National Longitudinal Survey of Freshman. Cross-sectional and longitudinal regression-based moderation models were conducted with PROCESS 2.13 for SPSS.

Results: Lighter skin color nullified the association between prejudice and recent depression for Asian American females. This moderating effect did not hold over time with regards to depression symptoms 1 year later. Additionally, prejudice predicted psychological distance to other Asian students 1 year later among females rated as lighter in skin color, whereas prejudice was tied to psychological closeness for females with darker skin ratings.

Conclusions: Results highlight skin color as a pertinent factor relevant to the short-term and long-term mental health and social experiences of Asian American women in particular.

County governing boards: Where are all the women?

County governing boards: Where are all the women? By Leander Kellogg et al.
Politics, Groups, and Identities, http://www.tandfonline.com/doi/abs/10.1080/21565503.2017.1304223?journalCode=rpgi20

Abstract: This research seeks to explore the extent of women representation on county governing boards and tests several hypotheses to explain variation in representation. This study evaluates a random sample of 394 of the more than 3000 counties in the United States. Half of the counties did not have any women serving on their county governing boards. A two-stage analysis using first a logit model sought to explain when counties have women commissioners and then a truncated regression analysis evaluated the percentage of women serving on county boards. Size of governing boards, size of government, religious adherence, and two election formats had significant effects in explaining when a county had women commissioners. Three variables (religious adherence, level of support for President Obama, and size of governing boards) were significant in explaining the percentage of women serving on county governing boards with size of the boards operating opposite of the hypothesized direction.

Does the Stock Market Boost Firm Innovation? Evidence from Chinese Firms

Does the Stock Market Boost Firm Innovation? Evidence from Chinese Firms. By Hui He, Hanya Li, Jinfan Zhang. IMF Working Paper No. 17/147, http://www.imf.org/en/Publications/WP/Issues/2017/06/29/Does-the-Stock-Market-Boost-Firm-Innovation-Evidence-from-Chinese-Firms-44983?cid=em-COM-123-35527

Summary: The paper analyses the effect of the stock market on firm innovation through the lens of initial public offering (IPO) using uniquely matched Chinese firm-level data. We find that IPOs lead to an increase in both the quantity and quality of firm innovation activity. In addition, IPOs expand a firm’s scope of innovation beyond its core business. The impact of IPOs on firm innovation varies across financial constraints, corporate governance, and ownership structures. Our results further illustrate that IPOs induce a firm to increase the number of inventors and enable better retention of existing inventors after the IPO. Finally, we show that the enhanced innovation activity resulting from IPOs increases a firm’s Tobin’s Q in the long run.

More politicians, more corruption: Evidence from Swedish municipalities

More politicians, more corruption: Evidence from Swedish municipalities. By Andreas Bergh, Günther Fink & Richard Öhrvall. Public Choice (2017), https://link.springer.com/article/10.1007/s11127-017-0458-4

Abstract: In the literature on political economy and public choice, it is typically assumed that government size correlates positively with public corruption. The empirical literature, however, is inconclusive, owing to both measurement problems and endogeneity. This paper creates a corruption index based on original data from a survey covering top politicians and civil servants in all Swedish municipalities. The effect of more politicians on corruption problems is analyzed using discontinuities in the required minimum size of local councils. Despite the fact that Sweden consistently has been ranked among the least corrupt countries in the world, the survey suggest that non-trivial corruption problems are present in Sweden. Municipalities with more local council seats have more reported corruption problems, and the regression discontinuity design suggests that the effect is causal.

Deradicalizing Detained Terrorists

Marc-Andre Lafreniere, and Jocelyn J. Belanger. 2017. "Deradicalizing Detained Terrorists." Political Psychology (May). http://onlinelibrary.wiley.com/doi/10.1111/pops.12428/abstract

Abstract: Deradicalization of terrorists constitutes a critical component of the global “war on terror.” Unfortunately, little is known about deradicalization programs, and evidence for their effectiveness is derived solely from expert impressions and potentially flawed recidivism rates. We present the first empirical assessment of one such program: the Sri Lankan rehabilitation program for former members of the Liberation Tigers of Tamil Eelam (a terrorist organization that operated in Sri Lanka until their defeat in 2009). We offer evidence that deradicalization efforts that provided beneficiaries with sustained mechanisms for earning personal significance significantly reduced extremism after 1 year (Study 1). We also found that upon release, beneficiaries expressed lower levels of extremism than their counterparts in the community (Study 2). These findings highlight the critical role of personal significance in deradicalization efforts, offer insights into the workings of deradicalization, and suggest practical methods for improving deradicalization programs worldwide.

Cultural evolution of military camouflage

Cultural evolution of military camouflage. By Laszlo Talas, Roland Baddeley & Innes Cuthill
Philosophical Transactions of the Royal Society: Biological Sciences, July 5, 2017, https://www.ncbi.nlm.nih.gov/pubmed/28533466

Abstract: While one has evolved and the other been consciously created, animal and military camouflage are expected to show many similar design principles. Using a unique database of calibrated photographs of camouflage uniform patterns, processed using texture and colour analysis methods from computer vision, we show that the parallels with biology are deeper than design for effective concealment. Using two case studies we show that, like many animal colour patterns, military camouflage can serve multiple functions. Following the dissolution of the Warsaw Pact, countries that became more Western-facing in political terms converged on NATO patterns in camouflage texture and colour. Following the break-up of the former Yugoslavia, the resulting states diverged in design, becoming more similar to neighbouring countries than the ancestral design. None of these insights would have been obtained using extant military approaches to camouflage design, which focus solely on concealment. Moreover, our computational techniques for quantifying pattern offer new tools for comparative biologists studying animal coloration.

When Criticism is Ineffective: The Case of Historical Trauma and Unsupportive Allies

Hirschberger, G., Lifshin, U., Seeman, S., Ein-Dor, T., and Pyszczynski, T. (2017) When Criticism is Ineffective: The Case of Historical Trauma and Unsupportive Allies. Eur. J. Soc. Psychol., doi: 10.1002/ejsp.2253, http://onlinelibrary.wiley.com/doi/10.1002/ejsp.2253/abstract

Abstract: Three studies examined the effect of historical trauma reminders and criticism from international allies on attitudes toward current conflicts. In Study 1, Israeli participants (N = 116) were primed with the Holocaust, and read either that US President Obama supports Israel's right to defend itself and attack Iran, or that he opposes such action. Then, support for preemptive violence was assessed. Study 2 (N = 133) replicated this design, comparing inclusive and exclusive framings of the Holocaust. Study 3 (N = 478), examined the effect of Holocaust reminders and criticism from the EU on attitudes toward militant policies against Palestinians. All three studies found that Holocaust primes juxtaposed with international criticism increased support for aggression, especially under exclusive framings of the Holocaust. Study 3, however, found this effect only among left-wing participants. These findings indicate that when historical trauma is salient, international criticism may be ineffective and may even backfire.

Does Competition Reduce Racial Discrimination in Lending?

Does Competition Reduce Racial Discrimination in Lending? By Greg Buchak & Adam Tejs Jørring
University of Chicago Working Paper, April 2017. http://home.uchicago.edu/~buchak/papers/mortgage_discrimination.pdf

Abstract: This paper examines whether increases in bank competition reduce discriminatory practices in mortgage lending. Lenders are significantly less likely to approve black applicants' loan applications despite facing similar credit risk. However, following the relaxation of interstate bank branching laws in the 1990s, increases in local lending competition reduced the approval differential between potential white and black borrowers by roughly one quarter. The reduction was driven both by incumbent lenders altering lending policies to avoid losing market share and by the entry of new banks. The results suggest strong complementaries between direct regulation and the competition mechanism. In particular, direct regulation is effective against large lenders where statistical proof problems are less severe, while competition provides incentives to smaller, harder to regulate lenders.

Gender Equality in Mortgage Lending

Fang, L. and Munneke, H. J. (2017), Gender Equality in Mortgage Lending. Real Estate Economics. doi:10.1111/1540-6229.12198

Abstract: Using a sample of 30-year fixed-rate subprime mortgage loans, this paper empirically examines whether gender inequality exists in the mortgage market, specifically, whether a borrower's gender affects the loan contract rate charged, beyond the impact of the borrower's probability of default and prepayment. The results, based on a competing-risks loan hazard model, reveal that borrowers of different gender have different loan termination patterns. After controlling for the probability of a borrower defaulting or prepaying, female borrowers pay higher contract rates in the subprime mortgage market over the study period.

Offspring of parents who were separated and not speaking to one another have reduced resistance to the common cold as adults

Offspring of parents who were separated and not speaking to one another have reduced resistance to the common cold as adults. By Michael L. M. Murphy, Sheldon Cohen, Denise Janicki-Deverts, and William J. Doyle
Proceedings of the National Academy of Sciences, http://www.pnas.org/content/114/25/6515.abstract

Significance: Adults whose parents separated during childhood are at increased risk for poorer health, although the underlying mechanisms remain unclear. Furthermore, increasing evidence suggests that aspects of the family environment following parental separation better predict a child’s adjustment than the separation itself. Using a viral challenge study, we found that adults whose parents separated but remained on speaking terms during childhood were no more likely to develop a cold when exposed to a cold-causing virus than adults from intact childhood families. However, adults whose parents separated and did not speak to each other during childhood were more than three times as likely to develop a cold following viral exposure. This increased risk was attributed to heightened inflammation in response to infection.

Abstract: Exposure to parental separation or divorce during childhood has been associated with an increased risk for physical morbidity during adulthood. Here we tested the hypothesis that this association is primarily attributable to separated parents who do not communicate with each other. We also examined whether early exposure to separated parents in conflict is associated with greater viral-induced inflammatory response in adulthood and in turn with increased susceptibility to viral-induced upper respiratory disease. After assessment of their parents’ relationship during their childhood, 201 healthy volunteers, age 18–55 y, were quarantined, experimentally exposed to a virus that causes a common cold, and monitored for 5 d for the development of a respiratory illness. Monitoring included daily assessments of viral-specific infection, objective markers of illness, and local production of proinflammatory cytokines. Adults whose parents lived apart and never spoke during their childhood were more than three times as likely to develop a cold when exposed to the upper respiratory virus than adults from intact families. Conversely, individuals whose parents were separated but communicated with each other showed no increase in risk compared with those from intact families. These differences persisted in analyses adjusted for potentially confounding variables (demographics, current socioeconomic status, body mass index, season, baseline immunity to the challenge virus, affectivity, and childhood socioeconomic status). Mediation analyses were consistent with the hypothesis that greater susceptibility to respiratory infectious illness among the offspring of noncommunicating parents was attributable to a greater local proinflammatory response to infection.

The Acquisitive Nature of Extraverted CEOs

The Acquisitive Nature of Extraverted CEOs. By Shavin Malhotra et al.
Administrative Science Quarterly, https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2973018

Abstract: This study examines how extraversion, a personality trait that signifies more or less positive affect, assertive behavior, decisive thinking, and desires for social engagement, influences chief executive officers’ (CEOs’) decisions and the ensuing strategic behavior of firms. Using a novel linguistic technique to assess personality from unscripted text spoken by 2,381 CEOs of S&P 1500 firms over ten years, we show that CEOs’ extraversion influences the merger and acquisition (M&A) behavior of firms above and beyond other well-established personality traits. We find that extraverted CEOs are more likely to engage in acquisitions, and to conduct larger ones, than other CEOs and that these effects are partially explained by their higher representation on boards of other firms. Moreover, we find that the acquisitive nature of extraverted CEOs reveals itself particularly in so-called “weaker” situations, in which CEOs enjoy considerable discretion to behave in ways akin to their personality traits. Subsequent analyses show that extraverted CEOs are also more likely than other CEOs to succeed in M&As, as reflected by stronger abnormal returns following acquisition announcements.

Pupillary Responses to Words That Convey a Sense of Brightness or Darkness

Pupillary Responses to Words That Convey a Sense of Brightness or Darkness. By Sebastiaan Mathôt, Jonathan Grainger & Kristof Strijkers
Psychological Science, https://www.ncbi.nlm.nih.gov/pubmed/28613135

Abstract: Theories about embodiment of language hold that when you process a word’s meaning, you automatically simulate associated sensory input (e.g., perception of brightness when you process lamp) and prepare associated actions (e.g., finger movements when you process typing). To test this latter prediction, we measured pupillary responses to single words that conveyed a sense of brightness (e.g., day) or darkness (e.g., night) or were neutral (e.g., house). We found that pupils were largest for words conveying darkness, of intermediate size for neutral words, and smallest for words conveying brightness. This pattern was found for both visually presented and spoken words, which suggests that it was due to the words’ meanings, rather than to visual or auditory properties of the stimuli. Our findings suggest that word meaning is sufficient to trigger a pupillary response, even when this response is not imposed by the experimental task, and even when this response is beyond voluntary control.
