Implications of evidence-based practice for community health

Evidence-based practice, developed in clinical medicine, is being applied to community health programs. Barriers to implementation of evidence-based practice noted in clinical medicine are likely to exist in community health settings and may be complicated by the nature of community health programs. These barriers include accessibility and availability of relevant data, social and political considerations of program decision-making, and conflicting expectations for evaluation research. This paper discusses barriers to both amassing evidence for practice and using evidence for decision-making in community health. The potential for conflict between practice goals set by evidence-based thinking and those set by community health organizations is also discussed. Implications for evaluations of community health programs are raised and recommendations for improving access to and use of evaluation information are made.     

A policy‐modeling approach to examining fairness judgments in organizational acquisitions

Organizational acquisitions may be characterized by the degree of friendliness or hostility as well as the degree of autonomy or absorption of the organizations following the merger. This study examined judgments of fairness across four types of organizational acquisitions. Students read fictitious newspaper accounts of a university acquisition and rated their expectations and perceptions of fairness about possible changes. Results indicated that in an acquisition, both the procedures used and the outcomes provided influenced how fair the acquisition was perceived. As predicted, the relative importance of procedures and outcomes in overall perceptions of fairness shifted depending on the context of the acquisition. As the desirability of the acquisition increased, individuals placed greater importance on the procedural elements. In a friendly and low integration acquisition, the processes and outcomes became equally important. Individuals faced with a high integration acquisition expected more unfair changes and fewer fair changes to occur. Furthermore, these results highlight the importance expectations play in perceptions of fairness. The type of acquisition will influence expectations for fair treatment. Under less desirable conditions (hostile and high‐integration mergers), organizations should take steps early in the process to manage fairness perceptions.

An Influence of Positive Affect on Decision Making in Complex Situations: Theoretical Issues With Practical Implications

This article reviews evidence indicating that, in most circumstances, positive affect enhances problem solving and decision making, leading to cognitive processing that is not only flexible, innovative, and creative, but also thorough and efficient. These results have implications regarding consumers’ potential reactions to affect generated by ads, products, consumption situations, and service encounters. These cognitive effects of positive affect are considered in the context of effects on social interaction that show that positive affect leads to helping, generosity, and interpersonal understanding. Together, these findings suggest implications especially for customer satisfaction, and particularly for a role for employee positive affect, or employee satisfaction, in generating customer satisfaction. Moreover, studies specifically in the domain of medical decision making and problem solving indicate that these implications would apply to the specific areas of doctor–patient interaction, medical decision making, and medical consumer satisfaction. Finally, it is suggested that the benefits of positive affect be considered when formulating healthcare policy and be included in economic models and policy decisions more generally as well.     

Genetic Influences on Anxiety in Children: What we’ve Learned and Where we’re Heading

Anxiety is a common problem, typically beginning early in life. This article explores reasons for individual differences in levels of anxiety among children, by reviewing the genetic literature. The plethora of research to date has demonstrated clearly that both genes and environmental influences play important roles in explaining differences in levels of anxiety of various types among children. This has encouraged researchers to search for specific genes and environmental influences upon anxiety. Despite important progress in identifying links between anxiety and specific genes—including associations between serotonin and dopamine genes and different symptoms of anxiety—overall, progress has been slow because multiple genes of small effect size are likely to influence anxiety. This article explains how the hunt for genes involved in anxiety is likely to benefit from genetically sensitive research, which examines the co-occurrence of symptoms; includes measures of the environment; and examines endophenotypes and risk pathways.     

Familiarization effects for bilingual letter detection involving translation or exact text repetition.

In two experiments, English-Spanish bilinguals read passages, performing letter detection on some passages by circling target letters as they read. Detection passages were sometimes familiarized (primed) by prior reading of the same passage or a translation of it. Participants detected letters in English passages in Experiment 1 and in Spanish passages in Experiment 2. For both experiments, a missing letter effect occurred (depressed detection accuracy on frequent function words relative to less frequent content words). Familiarization promoted overall improvements in letter detection only for English passages, suggesting that reprocessing benefits depend on high language fluency. For Spanish passages, cognates engendered greater error rates than noncognates; the visual similarity of Spanish and English cognates apparently enabled faster identification of Spanish cognates in a way unaffected by familiarization of the whole text passage. Priming by familiarized text was significantly higher when the passages were in the same language than when they were in different languages, suggesting that the reprocessing benefits are at the word level instead of the semantic level. These results are consistent with the GO model of reading (Greenberg, Healy, Koriat, & Kreiner, 2004) but require an expanded consideration of attention redistribution processes in that model.     

Differential effects of age-of-acquisition for concrete nouns and action verbs: evidence for partly distinct representations?

There is growing evidence that words that are acquired early in life are processed faster and more accurately than words acquired later, even by adults. As neuropsychological and neuroimaging studies have implicated different brain networks in the processing of action verbs and concrete nouns, the present study was aimed at contrasting reaction times to early and later-acquired action verbs and concrete nouns, in order to determine whether effects of word learning age express differently for the two types of words. Our results show that while word frequency affected both types of words in the same way, distinct learning age effects were observed for action verbs and concrete nouns. A further experiment specified that this difference was observed for verbs describing actions belonging to the human motor repertoire, but not for verbs denoting actions past this repertoire (e.g., to neigh). We interpret these data within a recently emerging framework according to which language processing is associated with sensory motor programs.     

Prefrontal cognitive ability, intelligence, Big Five personality, and the prediction of advanced academic and workplace performance

Studies 1 and 2 assessed performance on a battery of dorsolateral prefrontal cognitive ability (D-PFCA) tests, personality, psychometric intelligence, and academic performance (AP) in 2 undergraduate samples. In Studies 1 and 2, AP was correlated with D-PFCA (r=.37, p<.01, and r=.33, p<.01, respectively), IQ (r=.24, p<.05, and r=.38, p<.01, respectively), and Conscientiousness (r=.26, p<.05, and r=.37, p<.01, respectively). D-PFCA remained significant in regression analyses controlling for intelligence (or g) and personality. Studies 3 and 4 assessed D-PFCA, personality, and workplace performance among (a) managerial-administrative workers and (b) factory floor workers at a manufacturing company. Prefrontal cognitive ability correlated with supervisor ratings of manager performance at values of r ranging from .42 to .57 (ps<.001), depending on experience, and with factory floor performance at pr=.21 (p=.02), after controlling for experience, age, and education. Conscientiousness correlated with factory floor performance at r=.23.     

Gender Differences in Virtual Negotiation: Theory and Research

Social roles create conflicting behavioral expectations for female negotiators; however, virtual negotiations reduce social pressures. This paper reviews theoretical explanations on why men and women might differ in negotiations that occur through email, telephone, or video. Forty-three negotiation studies comparing face-to-face and virtual negotiations were examined for gender differences. All studies were reported in English but not limited to US participants. While many reports omitted gender information, meta-analytic findings supported the prediction that women would be more hostile in virtual compared to face-to-face negotiations, as well as finding no hostility difference for men between virtual and face-to-face negotiations. While negotiators overall were more successful face-to-face than virtually, results separated by gender did not find this effect.
