Do People Agree on How Positive Emotions Are Expressed? A Survey of Four Emotions and Five Modalities Across 11 Cultures

Journal of Nonverbal Behavior - While much is known about how negative emotions are expressed in different modalities, our understanding of the nonverbal expressions of positive emotions remains...     

Dynamic exchange networks

Considering the theoretical and empirical untenability of static exchange networks, researchers have asked how exchange outcomes change when links are added or deleted. The present paper assesses the validity of seemingly sensible propositions concerning the effects of adding and deleting a link on (i) the payoffs of the actors in the link, (ii) the payoffs of actors in neighboring links and (iii) the variance of payoffs in the exchange network. The propositions were examined by applying expected value theory (EVT) to all 13,597 networks up to size 8. All propositions were falsified. Some falsifications of propositions could be attributed to EVTs prediction that actors use sub-optimal exchange relations. Since other well-known theories of exchange, like power-dependence theory and network exchange theory, also predict that actors use sub-optimal relations, these results are robust to selection of the theory of exchange.     

Theories of network exchange: Anomalies,desirable properties,and critical networks

The present study evaluates four well-known theories of exchange in networks. In previous research these theories’ predictions were compared for a small set of networks using experimental data. We compared their predictions for all 12,112 networks up to size 8. By comparing these predictions we (i) identified anomalies in theories of network exchange, (ii) investigated to what extent the theories satisfy basic principles of exchange, (iii) identified ‘critical’ networks for which predictions are very different. We conclude that exchange in networks is not yet well understood.     

Happily ever after?

Eight months after filling out questionnaires, 23 dating couples and 15 living-together couples were recontacted about their relationships. A larger percentage of dating couples had married than had living-together couples. Lower scores on couple adjustment characterized couples who later separated, compared with those who stayed together or who married. Adjustment was measured in terms of the unique configuration of relationship variables for each group. It was concluded that marriage may be a less appropriate index of couple progress in courtship than aspects of interpersonal and personal development.     

Cooking Practices in the Kitchen—Observed Versus Predicted Behavior

Cross-contamination and undercooking are major factors responsible for campylobacteriosis and as such should be incorporated in microbiological risk assessment. A previous paper by van Asselt et al. ^{( 1 )} quantified cross-contamination routes from chicken breast fillet via hand, cutting board, and knife ending up in a prepared chicken-curry salad in the domestic kitchen. The aim of the current article was to validate the obtained transfer rates with consumer data obtained by video observations and microbial analyses of a home prepared chicken-curry salad. Results showed a wide range of microbial contamination levels in the final salad, caused by various cross-contamination practices and heating times varying from 2'44" to 41'30". Model predictions indicated that cooking times should be at least 8 minutes and cutting boards need to be changed after cutting raw chicken in order to obtain safe bacterial levels in the final salad. The model predicted around 75% of the variance in cross-contamination behavior. Accuracy of the model can further be improved by including other cross-contamination routes besides hands, cutting boards, and knives. The model proved to be fail-safe, which implies it can be used as a worst-case estimate to assess the importance of cross-contamination in the home.     

Reflecting on Grantee Evaluation Accountability to Funders: Exploring Power Dynamics with Grassroots Organizations in Communities of Color

Grassroots organizations in communities of color often struggle in their relationships with philanthropic partners, especially as it relates to the issue of accountability. This article focuses on exploring the nature of accountability within the social contract between the philanthropic sector and these grassroots organizations. Drawing on a review of the relevant literature and results of 11 structured interviews with leaders from the philanthropic sector and grassroots organizations in communities of color, key themes are identified. Recommendations are offered on how the hierarchy within the sector can be addressed and how the dialogue between these partners can be improved.     

Emotional labor and leadership: A threat to authenticity?

Building on the emotional labor and authentic leadership literatures, we advance a conceptual model of leader emotional displays. Three categories of leader emotional displays are identified: surface acting, deep acting and genuine emotions. The consistency of expressed leader emotions with affective display rules, together with the type of display chosen, combines to impact the leader's felt authenticity, the favorability of follower impressions, and the perceived authenticity of the leader by the followers. Emotional intelligence, self-monitoring ability, and political skill are proposed as individual differences that moderate leader emotional display responses to affective events. We also look at followers' trust in the leader and leader well-being as key outcomes. Finally, we explore the influence on leader emotional labor of contextual dimensions of the environment, including the omnibus (national and organizational culture, industry and occupation, organizational structure, time) and discrete (situational) context. Directions for future research are discussed.
