Modified goodness-of-fit test for the laplace distribution

In this paper critical values of the Anderson-Darling and Cra[macute]er-von Mises are given for the Laplace distribution for maximum likelihood estimation of the location and scale parameters. The power of these tests is investigated for a number of alternative distributions. The Anderson-Darling test yields higher power generally than the Cra[macute]er-von Mises test.     

A Bayesian Network Estimation of the Service‐Profit Chain for Transport Service Satisfaction

Bayesian network methodology is used to model key linkages of the service‐profit chain within the context of transportation service satisfaction. Bayesian networks offer some advantages for implementing managerially focused models over other statistical techniques designed primarily for evaluating theoretical models. These advantages are (1) providing a causal explanation using observable variables within a single multivariate model, (2) analysis of nonlinear relationships contained in ordinal measurements, (3) accommodation of branching patterns that occur in data collection, and (4) the ability to conduct probabilistic inference for prediction and diagnostics with an output metric that can be understood by managers and academics. Sample data from 1,101 recent transport service customers are utilized to select and validate a Bayesian network and conduct probabilistic inference.     

The contribution of network research to managerial culture and practice

Although research on social networks has gained significant influence in the academic world, several factors seem to have lowered its echo in the business world. It is still unclear how this fast-growing stream of research has translated into solid implications for managerial action and decision making. Based on a review of recent research, this paper attempts to provide evidence that network research does have practical relevance. We focus on five areas where network research has introduced new angles and renewed the understanding of how organizations should tackle management issues. We also suggest directions for future research, with the same objective of placing the emphasis on strengthening the contribution of the approach to management practices.     

Firm‐level Evidence on Gender Wage Discrimination in the Belgian Private Economy

In this paper we explore a matched employer–employee data set to investigate the presence of gender wage discrimination in the Belgian private economy labour market. Contrary to many existing papers, we analyse gender wage discrimination using an independent productivity measure. Using firm‐level data, we are able to compare direct estimates of a gender productivity differential with those of a gender wage differential. We take advantage of the panel structure to identify gender‐related differences from within‐firm variation. Moreover, inspired by recent developments in the production function estimation literature, we address the problem of endogeneity of the gender mix using a structural production function estimator alongside instrumental variable‐general method of moments (IV‐GMM) methods where lagged value of labour inputs are used as instruments. Our results suggest that there is no gender wage discrimination inside private firms located in Belgium, on the contrary.     

The Compassion Strategy: Race and the Gender Gap in Campaign 2000

Recent studies have shown that social "compassion" issues, andnot those directly linked to women’s interests, seem todrive the gender gap in presidential vote choice. Some of thesecompassion issues are associated with the plight of racial minoritiesin the media and in the minds of average citizens. Drawing ontheories of gender role socialization, we predict that traditionalpartisan stands on racial issues may help to explain the gendergap. Specifically, we hypothesize that the gap emerges becausemen and women react differently to cues about how compassionatecandidates are toward vulnerable social groups. In one experiment,we manipulate news information regarding George W. Bush’scommitment to blacks versus women. The gender gap is maximizedwhen Bush takes the traditional Republican stance, while itis reduced significantly when Bush espouses a more moderateposition. The gender gap is unaffected by variation in the positionthat Bush takes on women’s issues. In another experiment,we also find that the gender gap emerges when traditional partisanappeals are racialized. Finally, exposure to the 2000 RepublicanNational Convention, with its message of racial inclusion, boostedevaluations of Bush among women but not men.     

Information and communication technologies and migrant intimacies: the case of Punjabi youth in Manila

This article examines how South–South migrants use information and communication technologies (ICTs) in negotiating their encounters with traditional cultural imaginaries of intimacy. It focuses on second-generation Punjabi Indian youth in the Philippine capital of Manila. Through an ethnographic approach, it unpacks how these migrants harness technologies to steer through two particular ideals about the end-goal of intimate relationships: the Punjabi notion of arranged marriage and the Filipino notion of love marriage. I characterise how the young Punjabis use ICTs to enact what I call a ‘temporarily resolution’ to their migrant double consciousness about intimacy. I also describe how this temporary resolution continues to be entwined with the wider dynamics of multicultural relations in the Philippines. Ultimately, I aim to better understand the role of ICTs in migrant intimacies, especially within the realities of multiculturalism in a postcolonial city in the Global South.     

Individual vs. group decision-making: an experiment on dynamic choice under risk and ambiguity

This paper focuses on the comparison of individual and group decision-making, in a stochastic inter-temporal problem in two decision environments, namely risk and ambiguity. Using a consumption/saving laboratory experiment, we investigate behaviour in four treatments: (1) individual choice under risk; (2) group choice under risk; (3) individual choice under ambiguity and (4) group choice under ambiguity. Comparing decisions within and between decision environments, we find an anti-symmetric pattern. While individuals are choosing on average closer to the theoretical optimal predictions, compared to groups in the risk treatments, groups tend to deviate less under ambiguity. Within decision environments, individuals deviate more when they choose under ambiguity, while groups are better planners under ambiguity rather than under risk. Our results extend the often observed pattern of individuals (groups) behaving more optimally under risk (ambiguity), to its dynamic dimension.

     

Latino Adolescent Reproductive and Sexual Health Behaviors and Outcomes: Research Informed Guidance for Agency-Based Practitioners

Latinos are the largest and fastest growing minority youth group in the United States. Currently, Latino adolescents experience higher rates of teen pregnancy compared to any other racial or ethnic group and have disproportionately high levels of sexually transmitted infections and HIV. Latino teens are also affected by a number of social problems such as school dropout, poverty, depression and limited access to healthcare, which contributes to disparities in reproductive health outcomes for this population. Relatively few intervention research studies and programs have been dedicated to reducing sexual risk among Latino youth, despite their particular vulnerabilities in experiencing negative reproductive health outcomes. We provide recommendations for identifying the unique reproductive health needs of Latino youth and specific applied strategies so that agency-based social workers and other providers can develop family-based interventions that improve adolescent Latino sexual and reproductive health.     

Income inequality and self-rated health status: Evidence from the european community household panel

We examine the effect of income inequality on individualś self-rated health status in a pooled sample of 11 countries, using longitudinal data from the European Community Household Panel survey. Taking advantage of the longitudinal and cross-national nature of our data, and carefully modeling the self-reported health information, we avoid several of the pitfalls suffered by earlier studies on this topic. We calculate income inequality indices measured at two standard levels of geography (NUTS-0 and NUTS-1) and find consistent evidence that income inequality is negatively related to self-rated health status in the European Union for both men and women, particularly when measured at national level. However, despite its statistical significance, the magnitude of the impact of inequality on health is very small.
