Robust estimation of dynamic fixed-effects panel data models

This paper extends an existing outlier-robust estimator of linear dynamic panel data models with fixed effects, which is based on the median ratio of two consecutive pairs of first-order differenced data. To improve its precision and robustness properties, a general procedure based on higher-order pairwise differences and their ratios is designed. The asymptotic distribution of this class of estimators is derived. Further, the breakdown point properties are obtained under contamination by independent additive outliers and by the patches of additive outliers, and are used to select the pairwise differences that do not compromise the robustness properties of the procedure. The proposed estimator is additionally compared with existing methods by means of Monte Carlo simulations.     

‘I Became a Mom’: Identity Changes in Mothers Receiving Public Assistance

ABSTRACT

This phenomenological study used individual, semistructured, face-to-face interviews to explore motherhood experiences among 15 women receiving public assistance in a large urban area on the West coast. A primary phenomenon observed was that motherhood was described as an experience of identity change, with resulting emotional, behavioral, and sense-of-self changes. Within this broad theme, two categories emerged: the experience and process of change, and consequences of change. It was concluded that motherhood may serve as an important catalyst for change in some women and that the context of poverty is essential for understanding the motherhood experience. These results suggest that interventions aimed at leveraging emerging motherhood identities may be beneficial in setting women on the path out of poverty, drug addiction, and incarceration. Future research should examine the consequences of maternal change within the specific context of the stages of change documented in the recovery process from drug addiction.     

On generalized semi-Pareto and semi-Burr distributions and random coefficient minification processes

A characterization of Pareto type III distribution is obtained. As a generalization of the Pareto distribution, a new class of distributions called the generalized Pareto distributions is introduced and a characterization of this class is obtained. We introduce a new class of autoregressive models with semi-Pareto marginals and study its properties. As a generalization of semi-Pareto distribution, we introduce semi-Burr distribution and develop a random coefficient autoregressive model with semi-Burr marginal distributions.     

Maternal Sensitivity and Child Responsiveness: Associations with Social Context,Maternal Characteristics,and Child Characteristics in a Multivariate Analysis

This study examined unique associations of multiple distal context variables (family socioeconomic status [SES], maternal employment, and paternal parenting) and proximal maternal (personality, intelligence, and knowledge; behavior, self‐perceptions, and attributions) and child (age, gender, representation, language, and sociability) characteristics with maternal sensitivity and child responsiveness in 254 European American mothers and their firstborn 20‐month‐olds. Specific unique relations emerged in hierarchical regression analyses. Mothers who worked fewer hours per week and reported less dissonance in their husbands' didactic parenting, whose children spoke using more vocabulary, and who reported less limit setting in their parenting and attributed their parenting failures to internal causes were observed to be more sensitive in their interactions with their children. Children in higher SES families, whose mothers worked fewer hours and attributed their parenting failures to internal causes, and who themselves used more vocabulary were observed to be more responsive in their interactions with their mothers. Although potential associations are many, when considered together, unique associations with maternal sensitivity and child responsiveness are few, and some are shared whereas others are unique.     

ENHANCING DISCOURSE ON NEW TECHNOLOGY WITHIN HIGHER EDUCATION

Universities face challenges in creating and nurturing reflective discourse about ICTs within higher education. Constraints to this discourse include time-space compression caused by ICTs, and changing perceptions of the university's role in an information society. In answering these challenges, a call is made for elevating the role of higher education in public knowledge formation. Such a move reduces the constraints of time pressures by valuing discussion and debate and the time required for these activities, and questions authority and credibility gained solely due to practical and discursive technological competency. Thus, the question is not just to explore how communications technologies are shaping our experience of time and space, but to debate how we wish to use technologies and other means to shape and create the time and space in which meaningful human social and political life is possible. Institutions of higher education should both serve as sites for public knowledge formation, and as contributors to such initiatives in civic society.     

Theoretical, Empirical, and Practical Approaches to Intergroup Conflict

The study of intergroup relations has long been an interest of social scientists, particularly members of The Society for the Psychological Study of Social Issues. The articles in this issue offer a wide variety of theoretical, empirical, and practical approaches to understanding and resolving national and international group conflict. This introductory article summarizes the original social psychological work that laid the foundation for contemporary thinking on intergroup relations, and presents an overview of each of the contributions in this issue. Also discussed are applications of social psychology to real-world intergroup conflicts.     

Religiosity,Citizenship and Belonging: The Everyday Experiences of Young Australian Muslims

Abstract

Since 11 September 2001 Muslim Diasporas have emerged as objects of anxiety in Western societies. Underlying this (in)security-driven problematisation is the question of whether Muslims living in the West have the capacity to become fully active citizens while maintaining their religious beliefs, rituals and practices. This apprehension has prompted reactionary government programmes, particularly targeting young Muslims. Such responses fail to recognise the societal capacities that practising Muslims possess, including those informed by the ethical precepts of Islamic faith. This paper argues that it is timely to explore expressions of Islamic religiosity as they are grounded in everyday multicultural environments. The paper draws on survey data and interviews conducted with Muslims living in Melbourne, Australia. We take into consideration key variables of age and generation to highlight how young, practising Muslims enact citizenship through Islamic rituals and faith-based practices and traditions. The paper will draw from key findings to argue that these performances provide a foundation for exploring ways of ‘living’ together in a manner that privileges ethics central to Islamic faith traditions.     

ECONOMIC INTEGRATION,POLITICAL INTEGRATION OR BOTH?

We study the effects of economic and political integration by presenting a model in which firms compete with each other in both an economic market—where they produce a good and compete for market share—and in a political (rent seeking) market—where they compete for transfers from the government. Growth is driven by firms’ cost‐reducing innovation activity and economic and political integration affect firms’ incentive to innovate differently. In this setting, economic and political integration can be seen as complementary. Economic integration, when not accompanied by political integration, can lead to less innovation and slower growth as firms respond to increased competition in the economic market by focusing more on rent‐seeking activity. When economic integration is accompanied by political integration, innovation and growth will be stronger and welfare higher.
