‘The politics of free speech’

The present article addresses the support and supervisional relations of Palestinian Israeli single mothers vis-à-vis their families and communities. It links the theoretical discussion on intersectional analysis with power relations and gender. In this article I focus on the importance of employing analytical models that take into consideration the internal variance within this social category of ‘Palestinian Israeli single mothers' which emerge due to the contradictory social trends typifying Palestinian society in Israel today – models that examine the implications of the complexity of women's lives in discrete locations, the changes society is undergoing, together with processes of discrimination and the strengthening of conservative trends. The article is based on data gathered during in-depth, semi-structured interviews that were conducted and analyzed with a commitment to the principles of feminist research.     

Towards (Re)Conciliation: The Post-Colonial Economy of Giving

In this paper the author argues that the Chinese theory of All-under-Heaven is the best philosophy for world governance. All-under-Heaven is a deep world concept with a trinity of meanings: the earth, people's hearts and a world institution. And it introduces a political principle, ‘world-ness’, that arguably transcends the principle of ‘internationality’. The author argues that the theory of All-under-Heaven is a more appropriate ‘world theory’ than ‘international theory’ in dealing with world problems. The author also considers the philosophies of the UN and EU.     

A cognitive-behavioral plus exercise intervention for older adults with chronic back pain: race/ethnicity effect?

This pilot study examined the feasibility and potential efficacy of a self-management program for seniors with chronic back pain and assessed for possible race/ethnicity differences in program impact. Sixty-nine seniors (24 African Americans, 25 Hispanics, and 20 non-Hispanic Whites) enrolled in the 8-wk community-based program. Efficacy outcomes included pain-related disability as measured by the Roland Morris Disability Questionnaire (RMDQ), pain intensity, pain self-efficacy, depressive symptoms, social activity, and functional status. Eighty percent of enrollees completed the program. Clinically important decreases in RMDQ scores were found for non-Hispanic White (adjusted change score = -3.53), African American (-3.89), and Hispanic (-8.45) participants. Improvements in all other outcomes were observed, but only for Hispanic participants. Results confirm that implementation of the protocol in urban senior centers is feasible, and the program shows potential efficacy. The race/ethnicity differences observed in the current study merit further investigation.     

Urban flora in the Southeast Europe and its correlation with urbanization

Many studies have refuted the opinion that urban floras are poor in total species number and characterized primarily by neophytes. Also, it has been proved that urban flora differs from its surroundings, and at the same time reflects its richness. Our study focused on urban flora, structure and similarities, and the possible correlation with the urban attributes. Therefore, we selected 11 cities in Southeast Europe, which differ in the development of transportation networks (roads, rails and inland waterways) and population size. Next, we compared two sets of data (structure of urban flora and urban attributes) to define the correlation patterns. Analyzed urban floras were primarily distinguished by a total number of species, number of unique species and neophytes. Belgrade is a city with the highest urbanization level, the most species and the highest number of unique species and neophytes as well. Kosovska Mitrovica, Grocka and Po?arevac stand out by floristic richness. These cities have a high number of species, yet a small proportion of neophytes. Other cities are characterized by similar floristic structure, with a relatively similar proportion of neophytes and approximately similar number of unique species in relation to the total number. It can be concluded that other factors beside the chosen urban attributes have additional effects on floristic structure, except for the factor - the presence of neophytes. This is in accordance with predefining subjects, since urban attributes were chosen based on knowledge about important corridors for invasive species.     

Second-order properties of intraclass correlation estimators for a symmetric normal distribution

Consider the problem of estimating the intraclass correlation coefficient of a symmetric normal distribution under the squared error loss function. The general admissibility of the standard estimators of the intraclass correlation coefficient is hard to check due to their complicated sampling distributions. We follow the asymptotic decision-theoretic approach of Ghosh and Sinha (1981) and prove that the three standard intraclass correlation estimators (the maximum-likelihood estimator, the method-of-moments estimator and the first-order unbiased estimator) are second-order admissible for all p ≥ 2, p being the dimension of the distribution.     

Optimum Mixture Design for the Detection of Synergistic Effects

In mixture experiments, optimal designs for the estimation of parameters, both linear and non-linear, have been discussed by several authors. Optimal designs for the estimation of a subset of parameters have also been investigated. However, designs for testing the effects of certain factors and interactions have been studied only in the context of response surface models. In this article, we attempt to find the optimum design for testing the presence of synergistic effects in a mixture model. The classical F-test has been considered and the optimum design has been obtained so as to maximize the power of the test. It is observed that the barycenters are necessarily the support points of the trace-optimal design.
