Bayesian approach to change point problems

A Bayesian approach is considered to study the change point problems. A hypothesis for testing change versus no change is considered using the notion of predictive distributions. Bayes factors are developed for change versus no change in the exponential families of distributions with conjugate priors. Under vague prior information, both Bayes factors and pseudo Bayes factors are considered. A new result is developed which describes how the overall Bayes factor has a decomposition into Bayes factors at each point. Finally, an example is provided in which the computations are performed using the concept of imaginary observations.     

De Jure vs. De Facto Rights: A Response to “Human Rights: What the United States Might Learn from the Rest of the World and,Yes, from American Sociology”

Blau's ( 2016 ) argument for a Constitutional Project implies that changes in the U.S. Constitution would ensure fundamental adherence to human rights standards. We disagree with the assumption that legal and institutional instruments are guarantors of human rights practice. Instead, we see rights practices as the function of power struggles that include but go far beyond formal law. Instead, we emphasize an important distinction between de jure human rights instruments and de facto human rights practice, arguing that the focus on de jure instruments and legal discourse misses the significant effect of social movements and direct action that secure rights practice. De jure instruments may codify human rights and enumerate them as important, but they do not carry the authority of enforcement. We argue that the pursuit of human rights must be reframed to include both de jure and de facto human rights terrains. While charitable provisions from generous states can temporarily relieve specific human rights abuses, universal human rights practice requires establishing the fundamental political primacy of the people through the processes of the human rights enterprise.     

Diversification and Performance in Developed and Emerging Market Contexts: A Review of the Literature*

The link between diversification and performance has become an important topic for research in diverse fields such as strategic management, industrial organization and financial management. However, a synthesis of the research done in developed and emerging markets is missing. This paper attempts such a synthesis by comparing and contrasting the past cumulative empirical research evidence on the relationship between diversification and firm performance in the context of developed economies to the more recent work in the emerging economies. The empirical literature has been divided into three broad perspectives, and the paper highlights the considerable diversity in its findings in developed and emerging markets across each of these perspectives. Based on this study, it is proposed that related diversification is preferable in developed economies and should be based on specific resources, whereas unrelated diversification is appropriate in emerging economies and should be based on generic resources. Although agency problems exist in both contexts, it is argued that the type of problem differs in developed and emerging markets. The paper concludes by identifying three directions for future research. First, the relationship between diversification and performance should be examined across each industry separately and not in aggregate. Secondly, future research needs to examine the organizational mechanisms required to make diversification successful. Finally, the relationship needs to be examined under unstable and dynamic situations such as the current global economic downturn.     

Liminal Lives: South Asian Youth and Domestic Violence

This article examines domestic violence experiences among South Asian youth in the United States. The paper uses a broad definition of violence, a continuum which includes aggression, coercion, control, intimidation, assault, to accommodate the meanings suggested by the youth. The main argument of this paper is that the youth's experiences cannot be adequately explained with reference to individual deviance or traditional cultural norms of ethnic groups. Based on a sociological perspective of gender, this paper argues that these youth are placed between mainstream and ethnic gender regimes and their experience of domestic violence depends on how these regimes work in relation to each other. Thus their liminal social structural position emerges as a significant factor in their experiences of violence.

‘I’m a different kind of biracial’: how black/white biracial Americans with immigrant parents negotiate race

Increasingly, multiracial families have garnered scholarly attention. However, the roles of ethnicity and immigrant ties are largely absent in bi/multiracial studies. Drawing on 17 in-depth interviews with black/white biracial Americans with at least one immigrant parent, this study analyzes the dynamic interplay of race, ethnicity, and immigrant roots in the bi/multiracial community. Our findings show that participants struggle to articulate the meaning of race, and they assert specific racial/ethnic identities to circumvent stereotypical connotations of whiteness and blackness. We highlight how biracial Americans with immigrant ties – those who we might assume would have a limited understanding of race – voice clear understandings of racial superiority and inferiority, racial relations, and racial stereotypes. Emphasizing their ethnic roots is not only an attempt to accurately describe their ancestry; it also allows them to avoid the social consequences (i.e. stereotypes, discrimination, etc.) of being (half) white or (half) black.
