We consider the fraction of pairs of m distinct alternatives on which a social welfare function f may be nondictatorially independent and Pareto when the domain of f satisfies the free k-tuple property. When k = 4 we improve the existing upper bound to . When there are at least 26 alternatives and we obtain an original upper bound, . To obtain these results we define and analyze the graph formed from the nondictatorial independent and Pareto pairs and
combine the results of this analysis with known results from extremal graph theory.
The authors extend special thanks to the two reviewers and the editor for their comments. 相似文献

Limited empirical study of the career development of Asian Americans in general and Korean Americans in particular has been conducted. The authors present the results of a theory‐based exploration of the career goals of Korean American university students in which ethnic identity, self‐efficacy, outcome expectations, and career interests were used to predict goal intentions for science and nonscience careers. Outcome expectations and career interests predicted a moderate amount of variance in science career goal intentions and a moderate to large amount of variance in nonscience career goal intentions. Korean American students' career goal development seems similar to that of American college students. 相似文献

Variability has been demonstrated to be an operant dimension of behavior (Neuringer, 2002; Page & Neuringer, 1985). Recently, lag schedules have been used to demonstrate operant variability of verbal behavior in persons with a diagnosis of autism (e.g., Lee, McComas, & Jawor, 2002). The current study evaluated the effects of a Lag 1 schedule on the vocal variability of 2 nonverbal children with a diagnosis of autism. Results showed systematic increases in variability during the Lag 1 schedule. Implications of lag schedules for speech and language training are discussed. 相似文献

Treating clients from diverse cultural backgrounds, and supervising clinicians who are treating clients of the same ethnicity
and gender, are now common experiences in our mental health system. As the growth of minorities in the US greatly outpaces
the training of minority clinicians, more attention to these situations is needed. Operating from the premise that interpersonal
sensitivity is a fundamental aspect of cross-cultural and cross-ethnic sensitivity, we describe the treatment of a Latino
male by a Latino male clinician, in this case both of Puerto Rican descent. We outline the contours of the therapy with a
man whose life history included numerous incidents of humiliation and thwarted efforts at efficacy, mastery, agency, and competence,
resulting in an adult character structure based on shame and self-doubt. We also discuss the challenges to the clinician posed
by working with a man whose traditional upbringing mirrored his own, with all the positives and negatives that must be considered
in the countertransference. We describe clinical and cultural reasons for various interventions, and their resulting outcome.
The framework of a dynamic interpersonal therapy and the challenges of transference, countertransference, therapist disclosure,
and working-through are covered. 相似文献

The positive association between moderate alcohol consumption and wages is well documented in the economic literature. Positive
health effects as well as networking mechanisms serve as explanations for the “alcohol–income puzzle.” Using individual-based
microdata from the SOEP for 2006, we confirm that this relationship exists for Germany as well. More importantly, we shed
light on the alcohol–income puzzle by analyzing, for the first time, the association between beverage-specific drinking behavior
and wages. In our analysis, we disentangle the general wage effect of drinking into diverse effects for different types of
drinkers. Mincerian estimates reveal significant and positive relationships between wine drinkers and wages as well as between
multiple beverage drinkers and wages. When splitting the sample into age groups, the “drinking gain” disappears for employees
under the age of 35 and increases in size and significance for higher age groups. We also find a “beer gain” for the oldest
age group and male residents of rural areas as well as a “cocktail gain” for residents of urban areas. Several explanations
for our empirical results are discussed in view of the likelihood that the alcohol–income puzzle is a multicausal phenomenon.

In research on value similarity and transmission between parents and adolescents, no consensus exists on the level of value similarity. Reports of high‐value similarities coexist with reports of low‐value similarities within the family. The present study shows that different conclusions may be explained by the use of different measurement strategies. In addition, we demonstrate that measured value similarities may be biased by a cultural stereotype, that is, an indirectly measurable phenomenon outside the family most likely attributed to shared cultural experiences. We examined similarities in 8 social–cultural value orientations among fathers, mothers, and adolescents from 433 Dutch families. Results revealed different outcomes when using ordinary correlations (r), absolute difference scores (d), or profile correlations (q). Similarly, different influences of a cultural stereotype were found when applying different measurement strategies. We discuss which measurement strategies are best used under which circumstances and which role the cultural stereotype plays. 相似文献

In this article we make use of inclusive masculinity theory to explore online media representations of male homosexuality and masculinity within the increasingly popular combat sport of mixed martial arts (MMA). Adopting a case-study approach, we discuss narratives constructed around one aspirational male MMA fighter, Dakota Cochrane, whose history of having participated in gay pornography became a major talking point on a number of MMA discussion/community Web sites during early 2012. While these narratives attempted to discursively rescue Cochrane’s supposedly threatened masculinity, highlighting both his “true” heterosexuality and his prodigious fighting abilities, they also simultaneously celebrated the acceptance of homosexual men within the sport that Cochrane’s case implied. Thus, we suggest that these media representations of homosexuality and masculinity within MMA are indicative of declining cultural homophobia and homohysteria and an inclusive vision of masculinity, as previously described by proponents of inclusive masculinity theory. 相似文献

The empirical literature on the impact of HIV on the quality (Q) and quantity (N) of children provides limited and somewhat mixed evidence. This study introduces individual HIV risk perceptions, as a predictor of mortality, into a Q–N investment model. In this model, higher maternal mortality predicts lower N, while higher child mortality predicts lower Q. Thus, the two effects together make likely negative associations between HIV and both Q and N. Based on longitudinal micro-data on mothers and their children in rural Malawi, our results suggest that higher mothers’ reported HIV risk reduces both child quality, as reflected in children’s schooling and health, and child quantity, when the perceived risk is already moderate or high. The effects are sizable and, in the case of Q (schooling and health), are found for children and teenagers, both boys and girls, while in the case of N, they are found for young and mature women. 相似文献
