Based on research showing that alcohol expectancy and gender both play a role in sexual perceptions, we factorially crossed the apparent drinking status of yoked pairs consisting of a participant and a target person (a confederate posing as co-participant). Alcohol expectancy interacted with gender in complex ways to influence sexual perceptions. We also found behavioral effects: Men showed more erotic material to both male and female targets than women did. Men perceived the target as more sexually aroused by erotic material than women did. Men also showed more erotic material to drinking targets than to non-drinking targets. Sexual perceptions and erotica showing behavior were correlated significantly and positively. These findings are discussed in terms of implications for postdrinking heterosexual encounters. 相似文献
Social exclusion of those who challenge group norms was investigated by asking children and adolescents, adolescents, age 9–13 years (N = 381), to evaluate exclusion of group members who deviated from group norms. Testing predictions from social reasoning developmental theories of group‐based exclusion, children and adolescents evaluated exclusion based on group norms involving allocation of resources and group traditions about dress code. Exclusion of deviant members was viewed as increasingly wrong with age, but also varied by the type of norm the deviant challenged. Participants who reported disliking a deviant member who wanted to distribute money unequally also found it acceptable to exclude them. Those who disliked deviants who went against norms about dress codes did not think exclusion was warranted. These findings are discussed in the context of children's social‐cognitive development regarding peer rejection as well as the role played by moral judgment and group dynamics. 相似文献
Many studies have focussed upon Western countries, such as the United States and members of the European Union, and how they engage with foreign publics. There is also an increasing amount of attention being paid to non-Western countries. The debate on soft power, for instance, shows that the concept is perceived and applied in a manner that differs from Nye's vision. This present article seeks to examine and analyse how and why the Russian state engages foreign publics with different communicational means and methods. Relations and approaches are much more pragmatic in the current situation, ideology seems to have been discarded. The current foreign policy concept gives context to positioning Russia, which not only gives Russia a certain role, but one that is set in relation to other international actors. Although, not all countries are treated the same, a different approach based upon a different set of assumptions produces a different understanding as to what programmes and means are needed. This produces a difference in approach between Western countries and those countries on the territory of the Former Soviet Union. 相似文献
This study investigates the influence of crisis on leader use of charismatic rhetoric. We examine leader charismatic rhetoric across two major crises, longitudinally exploring potential long-term influences of charismatic rhetoric on perceptions of leader effectiveness. Using an inductive approach to theory generation, we draw upon findings from the data analysis of eight charismatic rhetoric constructs (collective focus, temporal orientation, followers' worth, similarity to followers, values and moral justifications, tangibility, action, and adversity) to advance propositions regarding potential time and ceiling effects of charismatic rhetorical leadership on followers. Additionally, we discuss the relationships between characteristics of the crisis and the use of charismatic rhetorical leadership. In doing so, we identify potential boundary conditions for the use of charismatic rhetoric (as an element of charismatic leadership) within the context of different crises. 相似文献
Urban land area is expanding worldwide and may contribute to long-term carbon (C) storage; however, little is known about potential drivers of soil C in urban areas. Residential areas are one of the largest urban land use zones and lawns can provide stable chronosequences for studying soil C dynamics. In residential lawns containing no trees (n?=?23), the relationships between soil C and four potential drivers [home age (1–51 years), yard maintenance practices (fertilization, irrigation, and bagging or mulching lawn clippings), soil nitrogen (N) and soil texture] were investigated. Soil C increased with home age at 0–15 cm depth by 0.026 kg C m?2?yr?1, declined by ?0.011 kg C m?2?yr?1 at 15–30 cm depth, and was stable at 30–50 cm depth. Soil C had a positive relationship with soil N (R2?=?0.55) at the 0–15 cm depth. Soil C and N were not related to yard maintenance practices or soil texture. The low soil C sequestration rate and limited relationships between soil C and home age, yard maintenance, soil N and soil texture may have resulted from the positive influence of Auburn’s humid, subtropical climate on residue decomposition. 相似文献
Because of the need for efficient, consistent strength measurements, the test-retest reliability of concentric, isometric, and eccentric strength; concentric work; and concentric power was determined in older women without a familiarization session. The reliability of measures derived from a single peak score were compared with those derived from an averaged score. On 2 occasions 25 older women with a mean age of 72 +/- 6 years performed 3 submaximal knee extensions and 5 maximal contractions on an isokinetic dynamometer at 90 degrees/s (CON), 0 degrees/s, and -90 degrees/s on both lower limbs. Statistical analyses for peak and averaged values (best 3 contractions of 5) exhibited good relative reliability (ICCs > .88), except for CON power. Typical error as a coefficient of variation and ratio limits of agreement for peak and averaged score values were larger than desired, with CON power scores demonstrating unacceptable error ranges. Although relative reliability of this 1-session assessment protocol was acceptable, further research is needed to determine whether additional practice trials could enhance absolute reliability. 相似文献
We examine the extent to which migration equilibria fail to exist in a global economy in which a specific division rule determines
the allocation of a perfectly divisible, nondisposable resource among individuals with single-peaked preferences who reside
in local economies. In particular, almost without exception, under the egalitarian, proportional, queuing, and uniform division
rules, migration equilibria fail to exist for some sets of preferences.

Decomposition of fertility into its age, period, and cohort components demonstrates the empirical importance of age and period. Of the two, less is known about the period dimension. A new measure of fertility, specific to race and birth order, is used to estimate the effects of annual change in unemployment, the marriage and unemployment rate, as well as annual change in contraceptive sterilization and change in the proportion of couples adopting the more effective (pill and IUD) methods introduced in the early 1960s, are all important determinants of fertility change, but their impact varies greatly by birth order. 相似文献
Environmental change and climate-related disasters are an under-examined factor impacting women’s health, globally. Drawing on ecofeminist theory, we conduct analyses examining if the HIV burden among women is higher in nations that experience suffering from droughts. Specifically, we posit that droughts, which typically impact more people and for greater lengths of time than other climate-related disasters, have a unique impact on women’s vulnerability to HIV/AIDS. We use a cross-national dataset of less-developed countries and ordinary least squares (OLS) regression to explore and compare relationships between suffering from drought and total HIV prevalence and suffering from drought and women’s proportion of HIV cases. Overall, the results demonstrate that while droughts have an inconsistent impact on total HIV prevalence, suffering from drought significantly increases the proportion of HIV cases among women in comparison to men, net of the impact of common economic, social, cultural, and political predictors. The findings suggest that suffering from drought differentially impacts women’s health in less-developed countries, where a number of mechanisms, such as transactional sex or displacement, likely underlie the associations identified.
