“Celebrities to lean on!” Perceived celebrity support across two cultures—Iran and the United States

Though many people loathe celebrities and their lifestyles, celebrities can also be perceived as being available to provide community support. The purpose of this study was to establish the psychometric properties of the Perceived Celebrity Support Inventory. The scale was developed to capture three aspects of perceived celebrity support to the community: instrumental (i.e., providing tangible and concrete assistance), informational (i.e., advice, explanation, and information), and emotional (i.e., empathizing, encouraging, listening, and comforting) support. Factor and item analyses have revealed robust psychometric properties in samples drawn from the United States (US) and Iran. The US sample perceived higher community support from celebrities than the Iranian sample. In the Iranian sample, perceived celebrity support for the community was associated with more positive attitudes and less hatred of celebrity culture. In the US, perceived celebrity support was associated with negative attitudes and elevated hatred towards celebrities. The findings advance the literature by providing an instrument with which to measure positive aspects of celebrity influence across cultures.     

Male HIV-1 transgenic rats show reduced cocaine-maintained lever-pressing compared to F344 wildtype rats despite similar baseline locomotion

The HIV-1 transgenic (Tg) rat model is valuable for understanding HIV-associated neurocognitive disorders (HAND) and accompanying substance use and misuse. Tg and F344/NHsd wildtype (WT) rats were allowed to self-administer intrajugular cocaine. For the first 7 sessions, neither genotype self-administered cocaine (0.1 mg/kg/infusion) on a fixed ratio 1 schedule. We thus implemented a lever–cocaine “autoshaping” session followed by a series of manipulations changing dose and reinforcement schedule. Tg rats self-administered much less cocaine than WT rats throughout the study. Of 8 Tg rats, 5 modestly increased self-administration from sessions 36–50. Of those, only 3 showed a lever discrimination. Of 10 WT rats, 8 acquired robust self-administration by session 19; all WT rats self-administered cocaine by the end of the study. WT and Tg rats had similar baseline locomotor activity in the self-administration chamber suggesting that the low levels of cocaine intake in the Tg rats did not reflect a nonspecific motor impairment in this rat strain. Concomitant measurement of activity with self-administration revealed activity increases that followed increased cocaine intake. That relation held in Tg rats. Therefore, the present study provides evidence that HIV-1 Tg rats are less sensitive to the reinforcing effects of cocaine than their F344 WT counterparts.     

College Arrests and Later Criminal Convictions: An Examination of the Cumulative Disadvantage of Misconduct While in College

Crimes committed by college students have recently revealed some disturbing forms of misconduct. We know little however, about the sustained criminal behavior of this group in the decades following college. This study assesses whether being arrested while attending college is associated with an adult criminal conviction, 14–17 years following the college years. Data included a matched sample of non-arrested college students during the years 1996–1999, matched by gender, year in school, and college affiliation. The findings reveal that postcollege conviction odds increase between 3.3 and 5.4 times if a student has been arrested while attending college. Dropping out of college is associated with an increase in the odds of later criminal conviction, but dropping out does not have multiplicative effects on arrest status in college and later criminal conviction. Being a first year student moderates the association between arrest status and criminal conviction following college.     

New Faces in a New Place: Long-Time Residents’ Perceptions of New Residents in an Oil Boomtown in the Bakken Oil Shale Region

ABSTRACT

In 2008, increased oil production in the Bakken oil shale region in western North Dakota sparked a rapid increase in population for the communities in that area. This study examines long-time residents’ perceptions of new residents moving into their community using quantitative methods. The findings reveal that long-time residents who reported an increase in fear of crime because of the oil boom in western North Dakota were less likely to have positive perceptions of new residents. In addition, long-time residents who viewed their community as a friendly place and its residents as trustworthy, and who attempted to interact with new residents, were more likely to report positive perceptions of new residents.     

Wisdom in a complex world: A situated account of wise reasoning and its development

Social issues (e.g., partisan politics, economic decisions, and interpersonal conflicts) often involve trade‐offs, necessitating the consideration of multiple interests. Such issues do not have simple answers and benefit from wise reasoning—a set of metacognitive strategies that guide people toward managing complexity and balancing different interests. We review recent advances in research on wise reasoning, including evidence pertinent to the question of wisdom's trait‐like and state‐specific features, how it varies across situations, and how one can develop it. Overall, empirical studies suggest that researchers can understand wisdom better by paying attention to its situated nature across time and contexts.     

Psychology through international congresses: differences between regions, countries, and congresses

A published database of presentations from the seven most recent International Congresses of Applied Psychology (ICAPs) was compared to a similar but unpublished database (Adair, Anguas-Plata, Unik, & Radons, 2009) on the International Congresses of Psychology (ICPs) for the years 1996-2004. Analyses revealed phenomena characteristic of attendance at both international congresses: Participation rates spike dramatically for host countries; less dramatic regional surges in participation occur when the congress is held in a neighbouring country. Psychologists from 117 different countries participated in the seven recent congresses (ICAP and ICP) from 1994 to 2006. Overall ICP was double the size of ICAP, and represented a larger set of countries at each of its congresses. Regardless of location, most participants at both congresses came from the same 11 economically advantaged and seven majority-world countries. Congress presentations are dispersed across a much larger number of countries than are journal publications. The USA, for example, had modest 14.4% (ICAP) and 11.6% (ICP) presentation rates, much smaller than its majority share of publications (Adair, 2009 ). By contrast, the USA had the greater share of invited addresses at both ICAP (33.7%) and ICP (28.9%) congresses. Nonetheless, the majority-world countries contributing to both ICAP and ICP are clearly indicative of where the discipline is gaining strength and importance to international psychology. The emergence of Iran as a new leading national contributor to the two most recent international congresses, and the rise in the proportion of presentations by majority-world psychologists at ICAPs from only about one in five to more than one of every three presentations in recent congresses are findings consistent with Zakaria's (2008) analysis of changes taking place in the world. Within international congresses, certainly, the "rise of the rest" is changing the face of international psychology.     

On equivalence between a partial credit item and a set of independent Rasch binary items

Given a Masters partial credit item withn known step difficulties, conditions are stated for the existence of a set of (locally) independent Rasch binary items such that their raw score and the partial credit raw score have identical probability density functions. The conditions are those for the existence ofn positive values with predetermined elementary symmetric functions and include the requirement that then step difficulties form an increasing sequence.     

A bayesian procedure for mastery decisions based on multivariate normal test data

A Bayesian framework for making mastery/nonmastery decisions based on multivariate test data is described in this study. Overall, mastery is granted (or denied) if the posterior expected loss associated with such action is smaller than the one incurred by the denial (or grant) of mastery. An explicit form for the cutting contour which separates mastery and nonmastery states in the test score space is given for multivariate normal test scores and for a constant loss ratio. For multiple cutting scores in the true ability space, the test score cutting contour will resemble the boundary defined by multiple test cutting scores when the test reliabilities are reasonably close to unity. For tests with low reliabilities, decisions may very well be based simply on a suitably chosen composite score.This work was performed pursuant to Grant NIE-G-78-0087 with the National Institute of Education, Department of Health, Education, and Welfare, Huynh Huynh, Principal Investigator.

Some approximate tests for repeated measurement designs

Four approximate tests are considered for repeated measurement designs in which observations are multivariate normal with arbitrary covariance matrices. In these tests traditional within-subject mean square ratios are compared with critical values derived fromF distributions with adjusted degrees of freedom. Two of them—the approximate and the improved general approximate (IGA) tests—behave adequately in terms of Type I error. Generally, the IGA test functions better than the approximate test, however the latter involves less computations. In regards to power, the IGA test may compete with one multivariate procedure when the assumptions of the latter are tenable.The author wishes to thank Garrett K.
