BACKGROUND: Risk perceptions are central to many health behavior theories. However, the relationship between risk perceptions and behavior, muddied by instances of inappropriate assessment and analysis, often looks weak. METHOD: A meta-analysis of eligible studies assessing the bivariate association between adult vaccination and perceived likelihood, susceptibility, or severity was conducted. RESULTS: Thirty-four studies met inclusion criteria (N = 15,988). Risk likelihood (pooled r = .26), susceptibility (pooled r = .24), and severity (pooled r = .16) significantly predicted vaccination behavior. The risk perception-behavior relationship was larger for studies that were prospective, had higher quality risk measures, or had unskewed risk or behavior measures. CONCLUSIONS: The consistent relationships between risk perceptions and behavior, larger than suggested by prior meta-analyses, suggest that risk perceptions are rightly placed as core concepts in theories of health behavior.

A consensual, componential model of emotions conceptualises them as experiential, physiological, and behavioural responses to personally meaningful stimuli. The present review examines this model in terms of whether different types of emotion-evocative stimuli are associated with discrete and invariant patterns of responding in each response system, how such responses are structured, and if such responses converge across different response systems. Across response systems, the bulk of the available evidence favours the idea that measures of emotional responding reflect dimensions rather than discrete states. In addition, experiential, physiological, and behavioural response systems are associated with unique sources of variance, which in turn limits the magnitude of convergence across measures. Accordingly, the authors suggest that there is no "gold standard" measure of emotional responding. Rather, experiential, physiological, and behavioural measures are all relevant to understanding emotion and cannot be assumed to be interchangeable.

Genetic linkage maps based on restriction fragment length polymorphisms are useful for many purposes; however, different populations are required to fulfill different objectives. Clones from the linkage map(s) are subsequently probed onto populations developed for special purposes such as gene tagging. Therefore, clones contained on the initial map(s) must be polymorphic on a wide range of genotypes to have maximum utility. The objectives of this research were to (i) calculate polymorphism information content values of 51 low-copy DNA clones and (ii) use the resulting values to choose potential mapping parents. Polymorphism information content was calculated using gene diversity by classifying restriction fragment patterns on a diverse set of 18 wheat genotypes. Combinations of potential parents were then compared by examining both the proportion of polymorphic clones and the likelihood that those mapped clones would give a polymorphism when used on other populations. Genotype pairs were identified that would map more highly informative DNA clones compared with a population derived from the most polymorphic potential parents. The methodologies used to characterize clones and rank potential parents should be applicable to other species and types of markers as well.

Abstract A new correlation-based transition model has been developed, which is based strictly on local variables. As a result, the transition model is compatible with modern computational fluid dynamics (CFD) approaches, such as unstructured grids and massive parallel execution. The model is based on two transport equations, one for intermittency and one for the transition onset criteria in terms of momentum thickness Reynolds number. The proposed transport equations do not attempt to model the physics of the transition process (unlike, e.g., turbulence models) but form a framework for the implementation of correlation-based models into general-purpose CFD methods. Part I (this part) of this paper gives a detailed description of the mathematical formulation of the model and some of the basic test cases used for model validation, including a two-dimensional turbine blade. Part II (Langtry, R. B., Menter, F. R., Likki, S. R., Suzen, Y. B., Huang, P. G., and Völker, S., 2006, ASME J. Turbomach., 128(3), pp. 423–434) of the paper details a significant number of test cases that have been used to validate the transition model for turbomachinery and aerodynamic applications. The authors believe that the current formulation is a significant step forward in engineering transition modeling, as it allows the combination of correlation-based transition models with general purpose CFD codes.

This study examined the contribution of two concepts to the conventional view of commitment: foci of commitment, the individuals and groups to whom an employee is attached, and bases of commitment, the motives engendering attachment. Commitment to top management, supervisor, and work group were important determinants of job satisfaction, intent-to quit, and prosocial organizational behaviors over and above commitment to an organization. Compliance, identification, and internalization as bases of commitment were unique determinants above and beyond commitment to the foci.

This article examines the effects of three major revenue strategies in nonprofit organizations. Evolving resource dependence is demonstrated by the shifting reliance on each source of funds: private contributions, government funding, and commercial activities. A wide-ranging literature review is condensed into summary profiles comparing revenue volatility, goal displacement, process, and structure effects of each strategy. The profiles are drawn upon to anticipate potential advantages and disadvantages of increasingly diversified revenue strategies employed by nonprofits to combat resource dependence. The potential interaction effects raise critical but unanswered questions about nonprofit performance, legitimacy, and public policy issues.

With the availability of very large, relatively inexpensive main memories, it is becoming possible keep large databases resident in main memory In this paper we consider the changes necessary to permit a relational database system to take advantage of large amounts of main memory We evaluate AVL vs B+-tree access methods for main memory databases, hash-based query processing strategies vs sort-merge, and study recovery issues when most or all of the database fits in main memory As expected, B+-trees are the preferred storage mechanism unless more than 80--90% of the database fits in main memory A somewhat surprising result is that hash based query processing strategies are advantageous for large memory situations

The construct of experiential avoidance has become more frequently used by clinical researchers. Experiential avoidance involves the unwillingness to remain in contact with private experiences such as painful thoughts and emotions and is often proposed to be critical to the development and maintenance of psychopathology. This review summarizes the empirical studies on experiential avoidance as a factor in the etiology of maladaptive behavior and its relationship to specific diagnostic categories. Although some of the current literature suggests that experiential avoidance may be implicated in various forms of psychopathology, a fundamental limitation of this research is the lack of theoretical integration and refinement with regard to operationalizing and assessing experiential avoidance. Future studies should attempt to understand the core processes involved in experiential avoidance better, and then clearly operationalize the construct and determine its incremental validity relative to other constructs.

Effect size information is essential for the scientific enterprise and plays an increasingly central role in the scientific process. We extracted 147,328 correlations and developed a hierarchical taxonomy of variables reported in Journal of Applied Psychology and Personnel Psychology from 1980 to 2010 to produce empirical effect size benchmarks at the omnibus level, for 20 common research domains, and for an even finer grained level of generality. Results indicate that the usual interpretation and classification of effect sizes as small, medium, and large bear almost no resemblance to findings in the field, because distributions of effect sizes exhibit tertile partitions at values approximately one-half to one-third those intuited by Cohen (1988). Our results offer information that can be used for research planning and design purposes, such as producing better informed non-nil hypotheses and estimating statistical power and planning sample size accordingly. We also offer information useful for understanding the relative importance of the effect sizes found in a particular study in relationship to others and which research domains have advanced more or less, given that larger effect sizes indicate a better understanding of a phenomenon. Also, our study offers information about research domains for which the investigation of moderating effects may be more fruitful and provide information that is likely to facilitate the implementation of Bayesian analysis. Finally, our study offers information that practitioners can use to evaluate the relative effectiveness of various types of interventions.

Previous research has found that employee commitment and job performance are largely unrelated. However, prior work has not distinguished among individual foci (targets) and bases (motives) of commitment. We found, as expected, that commitment to supervisors was positively related to performance and was more strongly associated with performance than was commitment to organizations. Further, internalization of supervisors' and organizations' values was associated with performance but identification with these foci was not.

Metaphors linking spatial location and affect (e.g., feeling up or down) may have subtle, but pervasive, effects on evaluation. In three studies, participants evaluated words presented on a computer. In Study 1, evaluations of positive words were faster when words were in the up rather than the down position, whereas evaluations of negative words were faster when words were in the down rather than the up position. In Study 2, positive evaluations activated higher areas of visual space, whereas negative evaluations activated lower areas of visual space. Study 3 revealed that, although evaluations activate areas of visual space, spatial positions do not activate evaluations. The studies suggest that affect has a surprisingly physical basis.

Little is currently known about cheating among graduate business students. We collected data from more than 5,000 business (mostly MBA) and nonbusiness graduate students at 32 colleges and universities in the United States and Canada during the 2002–2003 and 2003–2004 academic years to test a series of hypotheses regarding the prevalence of graduate business student cheating and reasons why these students cheat. We found that graduate business students cheat more than their nonbusiness-student peers. Correlation results found cheating to be associated with perceived peer behavior, as well as the perceived certainty of being reported by a peer, and the understanding and acceptance of academic integrity policies by students and faculty. But, regression analysis results suggest that perceived peer behavior has the largest effect. Drawing from these findings and past research on undergraduate students, we propose strategies that business schools and faculty can use to promote academic integrity in graduate business programs.

A longitudinal investigation was conducted to explicate how the confluence of early behavioral dispositions, relational histories, and cognitive representations of the self and others contributes to internalizing problems, externalizing problems, and loneliness. One-hundred and ninety three girls, and 206 boys were assessed annually from age 5 (kindergarten) to age 10 (Grade 4). Early aggressive behavior was related to Grade 4 maladjustment directly and indirectly through subsequent relational stressors. Significant associations emerged between chronic friendlessness and rejection and later adaptation not accounted for by concurrent relational difficulties. Self- and peer beliefs partially mediated the relation between peer difficulties and internalizing problems and loneliness. The results highlight the utility of child-by-environment models as a guide for the investigation of processes that antecede psychosocial maladjustment.

AbstractCommunication is increasingly recognized as an important process in organizational crisis and crisis management. The Three Mile Island incident, the Bhopal Union Carbide accident, the crash of Northwest Airlines Flight 255, and the Exxon Valdez oil spill can all be described as specific, unexpected, and nonroutine events or series of events that created high levels of uncertainty and threat or perceived threat to an organization's high-priority goals. Crises disrupt employees and communities, damage corporate reputations, and cost hundreds of millions of dollars. Crises also serve as the impetus for investigations and organizational change. This review organizes a dynamic and growing body of communication and organizational literature dealing with crisis, including various developmental approaches used to describe crisis, decision making, public relations, rhetorical approaches, organizational legitimacy, and methodologies for crisis communication research. Research themes and new directions are identified. Weick's concept of enactment, stakeholder theory, and chaos theory are discussed as frameworks for emerging research directions.

Traditionally, nostalgia has been conceptualized as a medical disease and a psychiatric disorder. Instead, we argue that nostalgia is a predominantly positive, self-relevant, and social emotion serving key psychological functions. Nostalgic narratives reflect more positive than negative affect, feature the self as the protagonist, and are embedded in a social context. Nostalgia is triggered by dysphoric states such as negative mood and loneliness. Finally, nostalgia generates positive affect, increases self-esteem, fosters social connectedness, and alleviates existential threat.

Part II (this part) details a significant number of test cases that have been used to validate the transition model for turbomachinery and aerodynamic applications, including the drag crisis of a cylinder, separation-induced transition on a circular leading edge, and natural transition on a wind turbine airfoil. Turbomachinery test cases include a highly loaded compressor cascade, a low-pressure turbine blade, a transonic turbine guide vane, a 3D annular compressor cascade, and unsteady transition due to wake impingement. In addition, predictions are shown for an actual industrial application, namely, a GE low-pressure turbine vane. In all cases, good agreement with the experiments could be achieved and the authors believe that the current model is a significant step forward in engineering transition modeling.

In this target article, we argue that personality processes, personality structure, and personality development have to be understood and investigated in integrated ways in order to provide comprehensive responses to the key questions of personality psychology. The psychological processes and mechanisms that explain concrete behaviour in concrete situations should provide explanation for patterns of variation across situations and individuals, for development over time as well as for structures observed in intra–individual and inter–individual differences. Personality structures, defined as patterns of covariation in behaviour, including thoughts and feelings, are results of those processes in transaction with situational affordances and regularities. It cannot be presupposed that processes are organized in ways that directly correspond to the observed structure. Rather, it is an empirical question whether shared sets of processes are uniquely involved in shaping correlated behaviours, but not uncorrelated behaviours (what we term ‘correspondence’ throughout this paper), or whether more complex interactions of processes give rise to population–level patterns of covariation (termed ‘emergence’). The paper is organized in three parts, with part I providing the main arguments, part II reviewing some of the past approaches at (partial) integration, and part III outlining conclusions of how future personality psychology should progress towards complete integration. Working definitions for the central terms are provided in the appendix. Copyright © 2017 European Association of Personality Psychology

OBJECTIVE: Accurate measurement of beliefs about risk probability is essential to determine what role these beliefs have in health behavior. This study investigated the ability of several types of risk perception measures and of other constructs from health behavior theories to predict influenza vaccination. DESIGN: Prospective study in which students, faculty, and staff at 3 universities (N = 428) were interviewed in the fall, before influenza vaccine was available, and again early in the next calendar year. MAIN OUTCOME MEASURE: Self-reported influenza vaccination. RESULTS: Two interview questions that asked about feeling at risk and feeling vulnerable predicted subsequent behavior better (r = .44, p = .001) than 2 questions that asked for agreement or disagreement with statements about risk probability (r = .25, p = .001) or 4 questions that asked respondents to estimate the magnitude of the risk probability (r = .30, p = .001). Of the 4 perceived risk magnitude scales, a 7-point verbal scale was the best predictor of behavior. Anticipated regret was the strongest predictor of vaccination (r = .45, p = .001) of all constructs studied, including risk perceptions, worry, and perceived vaccine effectiveness. CONCLUSION: Risk perceptions predicted subsequent vaccination. However, perceived risk phrased in terms of feelings rather than as a purely cognitive probability judgment predicted better. Because neither feeling at risk nor anticipated regret is represented in the most commonly used theories of health behavior, the data suggest that these theories are missing important constructs.

Local firms in their home countries often engage in behavior that constitutes corruption, at least through some cultural lenses. One such practice is bribery of public officials. This study uses multilevel theory to address the question of why bribery activity of this type differs among countries. We analyze responses from nearly 4,000 firms worldwide using hierarchical linear modeling to investigate cross-level predictions about bribery. Drawing from anomie theory, we find support for country-level cultural and institutional drivers of firm-level bribery. We extend anomie theory by showing how firm-level pressures can encourage the supplying of bribes as a firm strategy.

Prior reviews and meta-analyses have supported the hypothesis that offender rehabilitation programs based on cognitive-behavioral principles reduce recidivism. This article quantitatively synthesizes the extant empirical evidence on the effectiveness of structured cognitive-behavioral programs delivered to groups of offenders. The evidence summarized supports the claim that these treatments are effective at reducing criminal behavior among convicted offenders. All higher quality studies reported positive effects favoring the cognitive-behavioral treatment program. Specifically, positive reductions in recidivism were observed for moral reconation therapy, reasoning and rehabilitation, and various cognitive-restructuring programs. The evidence suggests the effectiveness of cognitive skills and cognitive restructuring approaches as well as programs that emphasize moral teachings and reasoning.
