Reciprocal interactions between group perceptions of leader charisma and group mood through mood contagion

Departing from the static perspective of leader charisma that prevails in the literature, we propose a dynamic perspective of charismatic leadership in which group perceptions of leader charisma influence and are influenced by group mood. Based on a longitudinal experimental study conducted for 3 weeks involving 116 intact, self-managing student groups, we found that T1 group perceptions of leader charisma mediate the effect of leader trait expressivity on T2 positive and negative group moods. T2 positive and negative group moods influence T3 distal charisma perceptions by affecting T2 proximal perceptions of leader effectiveness. The current findings offer critical insights into (a) the reciprocal relationship between group perceptions of leader charisma and group mood, (b) the dynamic and transient nature of group perceptions of leader charisma, (c) the importance of understanding negative mood in charismatic leadership, and (d) the mechanism through which charismatic leadership perceptions can be formed and sustained over time.     

Family planning practice and women's fertility decision-making power

This paper investigates the effects of family planning practice on fertility decision-making power in South Korea. The log-linear analysis of the 1981 survey data by the Institute of Population and Health Services Research, Yonsei University, Seoul, Korea, shows that those urban and rural women who practice family planning or have experienced abortion exercise greater influence on a couple's fertility decision making than those who do not practice family planning or who have had no abortion experience. In addition, there is the interactive effect of abortion experience and contraceptive use on fertility decision making among urban women. This finding is significant because regardless of how birth control is available within a society, birth control use enhances women's decision making power where fertility is concerned.     

Occupational Status in 2000; Over a Century of Census-Based Measurement

The Nam–Powers–Boyd Occupational Status Scale for the year 2000 is introduced here. It is the sixth in a decennial series of such scales that were initiated at the Census Bureau a half century earlier. The bureau's examination of occupational status actually goes back to the end of the 19th century and its thread continues today. The historical background of the 2000 scale, the methodology for constructing the scores, some comparisons with other occupational scales, the 2000 scores themselves, and applications of the 2000 scores are presented.     

A Decision Support Tool to Compare Waterborne and Foodborne Infection and/or Illness Risks Associated with Climate Change

Climate change may impact waterborne and foodborne infectious disease, but to what extent is uncertain. Estimating climate‐change‐associated relative infection risks from exposure to viruses, bacteria, or parasites in water or food is critical for guiding adaptation measures. We present a computational tool for strategic decision making that describes the behavior of pathogens using location‐specific input data under current and projected climate conditions. Pathogen‐pathway combinations are available for exposure to norovirus, Campylobacter, Cryptosporidium, and noncholera Vibrio species via drinking water, bathing water, oysters, or chicken fillets. Infection risk outcomes generated by the tool under current climate conditions correspond with those published in the literature. The tool demonstrates that increasing temperatures lead to increasing risks for infection with Campylobacter from consuming raw/undercooked chicken fillet and for Vibrio from water exposure. Increasing frequencies of drought generally lead to an elevated infection risk of exposure to persistent pathogens such as norovirus and Cryptosporidium, but decreasing risk of exposure to rapidly inactivating pathogens, like Campylobacter. The opposite is the case with increasing annual precipitation; an upsurge of heavy rainfall events leads to more peaks in infection risks in all cases. The interdisciplinary tool presented here can be used to guide climate change adaptation strategies focused on infectious diseases.     

Husbands’ and wives’ time spent on housework: A comparison of measures

This study compares a series of estimates of the time spent on housework from survey responses and time‐use estimates from the Experience Sampling Method (ESM) obtained from husbands and wives in the Sloan 500 Family Study. These include estimates from husband's and wife's answers to questions about own time and spouse's time on household tasks, and time‐use estimates from the ESM. The three ESM estimates include primary activity only, primary plus secondary activity, and primary and secondary activity plus time spent thinking about household tasks. We find that estimates of hours spent on housework differ substantially and significantly across various measures, as does the absolute size of the gap between hours spent by husbands and wives. Share of housework done by husbands differs somewhat less.     

Two-Player Asymmetric Contests with Ratio-Form Contest Success Functions

I examine players' equilibrium effort levels in two-player asymmetric contests with ratio-form contest success functions. I first characterize the Nash equilibrium of the simultaneous-move game. I show that the equilibrium effort ratio is equal to the valuation ratio, and that the prize dissipation ratios for the players are the same. I also show that the prize dissipation ratio for each player is less than or equal to the minimum of the players' probabilities of winning at the Nash equilibrium and thus never exceeds a half. Then I examine how the equilibrium effort ratio, the prize dissipation ratios, and the players' equilibrium effort levels respond when the players' valuations for the prize or their abilities change.
