Does family support ensure the protection of children? Messages from child protection research

The history of child protection is, in many ways, a catalogue of changes arising from the political/professional interface tensions relating to a highly contentious area of public and professional policy. The latest contribution to this process is the Department of Health's 1995 publication Child Protection: Messages from Research. The overview of the studies recommends that there be a shift in resources and attitudes from an investigative approach to a family support perspective. Many local authorities have subsequently produced policies which will lead to referrals being recorded as ‘children in need’ rather than child protection. The ramifications of this change in approach are examined from the dual perspectives of policy and practice. The article suggests that while much of the change in emphasis is to be welcomed, the needs of the most severely abused children may be compromised by the new orthodoxy, as it is not based on the reality of the many problems encountered by children and professionals in child protection work. It is argued that a focus on practice issues needs to permeate all such documents. © 1998 John Wiley & Sons, Ltd.     

The Democratization of Data Science Education

Abstract

Over the last three decades, data have become ubiquitous and cheap. This transition has accelerated over the last five years and training in statistics, machine learning, and data analysis has struggled to keep up. In April 2014, we launched a program of nine courses, the Johns Hopkins Data Science Specialization, which has now had more than 4 million enrollments over the past five years. Here, the program is described and compared to standard data science curricula as they were organized in 2014 and 2015. We show that novel pedagogical and administrative decisions introduced in our program are now standard in online data science programs. The impact of the Data Science Specialization on data science education in the U.S. is also discussed. Finally, we conclude with some thoughts about the future of data science education in a data democratized world.     

Information technologies and the

conclusion The evolution in the role of middlemen has many important implications at the macro-economic level as well. In many markets, the negative employment effects of labor-saving technologies are offset by increases in the demand for labor as transaction costs fall and additional labor is needed to produce more goods and services. As discussed above, middlemen operate successfully in markets when private transactions are costly and inefficiencies exist. Many traditional aspects of this role are being replaced by information technologies. Generally, information technologies are a close substitute for match-making services, but are less suited for reducing privately held asymmetric information. The reduction in transaction costs and improved efficiencies in match mak-ing provided by information technologies increases the demand for expert services which further increases the returns to education and widens the earnings gap. The widening should be greatest in industries that concentrate on match-making services such as real estate, however a widening is likely to be present in most sectors. Middle-men with expertise beyond match making will remain viable, while those lacking value-adding expertise will be rapidly marginalized.

A Methodological Review of Exploratory Factor Analysis in Sexuality Research: Used Practices,Best Practices,and Data Analysis Resources

Sexuality researchers frequently use exploratory factor analysis (EFA) to illuminate the distinguishable theoretical constructs assessed by a set of variables. EFA entails a substantive number of analytic decisions to be made with respect to sample size determination, and how factors are extracted, rotated, and retained. The available analytic options, however, are not all equally empirically rigorous. We discuss the commonly available options for conducting EFA and which options constitute best practices for EFA. We also present the results of a methodological review of the analytic options for EFA used by sexuality researchers in more than 200 EFAs, published in more than 160 articles and chapters from 1974 to 2014, in a sample of sexuality research journals. Our review reveals that best practices for EFA are actually those least frequently used by sexuality researchers. We introduce freely available analytic resources to help make it easier for sexuality researchers to adhere to best practices when conducting EFAs in their own research.     

SENTIMENT BIAS AND ASSET PRICES: EVIDENCE FROM SPORTS BETTING MARKETS AND SOCIAL MEDIA

Previous research using attendance‐based proxies for sentiment bias in sports betting markets confirmed the presence of investor sentiment in these markets. We use data from social media (Facebook “Likes”) to proxy for sentiment bias and analyze variation in bookmakers' prices investor sentiment. Based on betting data from seven professional sports leagues in Europe and North America, we find evidence that bookmakers increase prices for bets on teams with relatively more Facebook “Likes,” indicating the presence of price‐insensitive investors with sentiment bias. These price changes do not affect informational efficiency in this market. (JEL L81, G14)     

Sexual Self-Concept: Testing a Hypothetical Model for Men and Women

One theoretical concept receiving modest attention in contemporary sex research is the sexual self-concept (SSC). However, a lack of cohesion within this research has culminated in a collection of SSC models which overlap one another but which are not exactly the same. Therefore, a unified conceptual model of SSC needs to be established. In addition, little research has examined potential differences between genders in SSC, as most SSC research has focused on women. Using Buzwell and Rosenthal's 1996 Buzwell , S. , & Rosenthal , D. (1996). Constructing a sexual self: Adolescents’ sexual self-perceptions and sexual risk-taking. Journal of Research on Adolescence , 6, 489–513.[Web of Science ®] , [Google Scholar] sexual selves model as a theoretical basis, a six-factor higher-order latent SSC model was tested using confirmatory factor analysis. Lower-order factors for this model included multidimensional sexual self-esteem and sexual self-efficacy factors, as well as unidimensional arousal, anxiety, exploration, and commitment factors. A five-factor latent model (after removing the commitment and the resistance sexual self-efficacy factors) was the best-fitting model. This model was then tested for measurement and structural invariance between genders. Results indicated that while the measurement of SSC was similar between men and women, structural invariance did not hold, as men had a significantly higher latent SSC score compared to women. These findings have important implications for sexual self-concept research, as well as contributing to better understanding of human sexuality.     

Effect of Environmental Risk and Externalizing Comorbidity on Internalizing Problems Among Economically Disadvantaged African American Youth

This study examined the effects of racial discrimination, community violence, and stressful life events on internalizing problems among African American youth from high‐poverty neighborhoods (N = 607; 293 boys; M_age = 16.0 years, SD = 1.44 years). Mediated effects via externalizing problems on these relations were also examined, given the high comorbidity rate between internalizing and externalizing problems. Externalizing problems partially mediated the effect of stressful life events on internalizing problems and fully mediated the effect of racial discrimination for boys but not for girls. Exposure to violence had a significant indirect effect on internalizing problems via externalizing problems. The findings call for greater attention to internalizing problems among African American youth and pathways to internalizing problems via externalizing problems.     

Pathways of Commitment to Wed: The Development and Dissolution of Romantic Relationships

The authors used changes in commitment to wed and reasons for these changes to classify couples into developmental pathways. Using data from a random sample of dating couples (N = 376), they found 4 distinct commitment processes: (a) dramatic, (b) conflict ridden, (c) socially involved, and (d) partner focused. Dramatic commitments were defined by relatively frequent fluctuations in commitment and negative attributions about their relationships. Conflict‐ridden commitments were defined by high levels of conflict and relatively frequent decreases in commitment. Individuals in socially involved commitments reported the highest proportion of positive dyadic attributions and references to joint interaction with social networks. Those in partner‐focused commitments reported a high proportion of positive dyadic attributions and references to interaction with partners. Types also differed on important relational variables, including satisfaction, love, ambivalence, worries about marriage, and leisure. Dramatic commitments were more likely than any other type to break up and showed an increased likelihood of regression in stage of involvement.     

THE EFFECTS OF ASSET FORFEITURE ON POLICING: A PANEL APPROACH

Asset forfeiture has proven highly controversial in the United States since its expansion in 1984. Most contentious is the widespread policy that allows police agencies to keep the assets seized, which both proponents and critics assert changes police behavior. From newly developed panel data sets, we find some statistical support for the proposition that police agencies change the intensity and pattern of policing in response to forfeiture. However, in economic terms these effects are very weak and do not support the proposition that forfeiture provides vital funds and incentives for crime policing. (JEL H39, H71, K42)
