Daily Fantasy Sports Players: Gambling,Addiction, and Mental Health Problems

Studies point to a relationship between fantasy sports/daily fantasy sports (DFS) play and gambling behavior. However, little is known about the nature of those relationships, particularly regarding the development of gambling problems. This study investigates the nature, frequency, and preferences of gambling behavior as well as problem gambling severity and comorbid conditions among DFS players. Data were collected from an epidemiologic survey of 3634 New Jersey residents on gambling and leisure activities. Participants were contacted by phone (land-line and cell) and online to obtain a representative, cross-sectional sample of non-institutionalized adults, aged 18 years or older. Excluding non-gamblers, the remaining 2146 participants, included in these analyses, indicated they had either played DFS (n = 299) or had gambled but not played DFS (1847) in the past year. Univariate comparisons and multiple logistic regression analyses were performed to identify the most significant characteristics and predictors of DFS players. Overall, a higher number of gambling activities, high frequency gambling, male gender, and reports of suicidal thoughts in the past year were most predictive of DFS players. Being Hispanic (vs. Caucasian) and/or single (vs. married or living with a partner) also doubled the odds of DFS play. Findings suggest that DFS players are characterized by high gambling frequency and problem severity and comorbid problems, notably suicidal ideation. Future research should examine the motivations and possible etiological sub-types of DFS players and the nature and course of DFS play, particularly in relation to gambling behavior and the development of gambling and other problems.     

Effects of Mindfulness-Based Therapies for Female Sexual Dysfunction: A Meta-Analytic Review

Mindfulness-based therapy (MBT) represents a potentially efficacious treatment for female sexual dysfunction (FSD). A number of recent trials assessing MBT for FSD have been published, but we are aware of no existing meta-analysis synthesizing these results. We conducted a literature review to identify all published trials of MBT for FSD. References of retrieved studies were searched and key authors were contacted with requests for complete but unpublished trials. Eleven trials, including a total of 449 participants, were identified. Two of these studies were under review at the time of the current analyses. Four trials utilized wait-list controls. All aspects of sexual function and subjective sexual well-being exhibited significant improvement during MBT, with effect sizes generally moderate. Controlled effect sizes versus wait list were of similar magnitude in most cases; however, they did not reach statistical significance for multiple outcome measures. Results for some outcomes were consistent with possible publication bias. For some outcomes, larger effect sizes tended to be reported in studies requiring participants to be in a romantic relationship or studies providing individual (versus group) therapy. MBT may be an efficacious intervention for FSD. However, important limitations of the current literature and future directions for research are discussed.     

The Multidimensionality of Prosocial Behaviors and Evidence of Measurement Equivalence in Mexican American and European American Early Adolescents

There is growing recognition of the need to examine distinct forms of prosocial behaviors and to conduct research on prosocial behaviors among ethnic minorities. Middle school students (mean age=12.67 years; 54% girls; European American, n=290; Mexican American, n=152) completed a multidimensional measure of prosocial behavior and measures of parental monitoring, externalizing behaviors, and religiosity. Results yield supportive evidence that anonymous, dire, emotional, compliant, public, and altruism are different forms of prosocial behaviors. Moreover, the measure of prosocial behaviors shows measurement equivalence properties across ethnicity and gender. The discussion focuses on the multidimensional nature of prosocial behaviors and implications for future research on prosocial behaviors.     

Discrimination and Adjustment for Mexican American Adolescents: A Prospective Examination of the Benefits of Culturally Related Values

Mexican American adolescents face disparities in mental health and academic achievement, perhaps in part because of discrimination experiences. However, culturally related values, fostered by ethnic pride and socialization, may serve to mitigate the negative impact of discrimination. Guided by the Stress Process Model, the current study examined risk and protective processes using a 2‐wave multi‐informant study with 750 Mexican American families. Specifically, we examined 2 possible mechanisms by which Mexican American values may support positive outcomes in the context of discrimination: as a protective factor (moderator) or risk reducer (mediator). Analyses supported the role of Mexican American values as a risk reducer. This study underscores the importance of examining multiple mechanisms of protective processes in understanding Mexican American adolescent resilience.     

毛泽东和农民:一个革命战略形成中的阶级和力量(上)

针对西方毛泽东研究领域比较盛行的那种认为毛泽东是农民革命家,而不是正统的马克思主义者,毛泽东对农民的重视决定了他是马克思主义的一个异端的观点,以成熟的方法论准备和扎实的文献学为基础,对这种观点进行了有理有据的反驳。毛泽东对农民的重视主要是一种战略和策略的需要,毛泽东从未否认工人阶级在革命中的领导地位,毛泽东是真正的马克思主义者。     

Theoretical and Methodological Perspectives on Domestic Violence: Implications for Social Action

Theoretical and methodological paradigms used by researchers and applied workers to conceptualise domestic violence are examined, with particular emphasis on the implications for social action. It is argued that the gender assumptions underlying the theoretical framework adopted are often implicit, unacknowledged, and that when they assume equal power between men and women may do a disservice to female victims. We maintain that the consequence of discrepant approaches of professionals encountering domestic violence is insufficient dialogue between researchers and applied workers, reducing the potential for effective social remedy. Some resolutions of this dilemma are proposed; specifically, these concern the adoption of feminist paradigms, the importance of making victims more visible, and empowering women to overcome violent oppression.     

The Ethical Implications of Mandatory Computer Ownership for Students

Many universities, colleges, and schools are contemplating mandatory computer ownership policies for undergraduate students. Review of these policies and the rhetoric employed in debate over such policies leaves some with strong misgivings. I suggest that seemingly widely held social values and a number of suspect assumptions underlie such policies, the questions raised by both their supporters and detractors, and the answers offered in response to those questions. Moreover, I identify four serious ethical concerns linked to mandatory computer ownership policies. Therefore, I argue that social science educators and practitioners have an ethical responsibility to resist such policies.     

A New Marriage Squeeze for Black Women: The Role of Racial Intermarriage by Black Men

Recent declines in the rate of marriage among Black women have been accompanied by substantial increases in rates of interracial marriage, especially between Black men and non‐Black women. Explanations for the retreat from marriage among Black women have focused on deficits in the quantity and quality of available partners, and the role of racial intermarriage largely has been ignored. This study examines the impact of interracial marriage by Black men on the marriage prospects of Black women. First, our analysis of data from the 1990 Integrated Public Use Microdata Series (IPUMS) reveals that intermarried Black men are selective of those with the highest levels of education, income, and occupational prestige. Second, multilevel analyses, using both the IPUMS and Panel Study of Income Dynamics, show that the level of intermarriage in metropolitan areas is significantly related to the marital behaviors of Black women. Local rates of intermarriage among Black men reduce the likelihood that Black women currently will be married and that they will make the transition to marriage. These effects are especially acute for highly educated Black women whose marriage markets are defined by those Black men who are most likely to intermarry. Finally, our analyses indicate that intermarriage affects the marital prospects of Black women by negatively affecting the pool of economically attractive marriage partners in the metropolitan area.     

The Perishability of Online Grocers*

In this article we explore the profitability of different operations models used by online grocers and develop a linear demand model in a competitive setting to better understand the trade‐offs made by two competing online grocers in choices for distribution strategy (leverage or direct) and product focus (perishable or nonperishable). We find that the results derived in the duopoly setting are different from those in a monopolistic setting. Specifically, we determine that there is a threshold value for the secondary competitive effects in the demand function that determines how the prices and profitability of an online grocer will be affected by the supply chain length of its competitor. There is also a threshold value for the ratio of supply chain lengths of the two competitors that determines whether product perishability increases or decreases profits. We demonstrate that the existence of this threshold is robust when considering capacity constraints. Further, we show, assuming that supply chain length can be optimized, how the relative size of the infrastructure change cost (when compared with that of the competitor) coupled with the perishability of the product determines the profitability of an investment leading to a shorter supply chain.
