Evaluation of the parameters of su by rational fractions

A rational fraction approximation is given for a function of one of the parameters defining Johnson's S_UError assessment for a segment of the domain of validity shows remarkable accuracy.     

Pax Rossica: The History of the Eurasianist Movement and the Fate of the Eurasianists

The radical changes that are taking place in the country, and which have led to a total crisis both in the political and the economic and social spheres, have affected all segments and groups of the population—men and women, rich and poor, old people and children, and those engaged in physical and mental work.     

On the one-sample location hypothesis for mixed bivariate data

We study a hypothesis testing problem involving the location model suggested by Olkin and Tate (1961). Specifically, we derive a likelihood ratio lest of the associated location hypothesis as an alternative to the conventional method of carrying out separate tests for each of the parameters. A small sample Monte Carlo comparison indicates the general superiority of the former in terms of statistical power. We also comment briefly on the properties of the test.     

Not Just about Posttraumatic Stress Disorder: A Call for Military-Centric Social Work

Most warriors do not get PTSD but can still be affected by war. The “military gestalt,” defined as the complex myriad of “all things military” including the functions, processes, and human elements related to combat, is seriously impacted by the warrior-in-combat construct that is reflective of the person-in-environment construct. Thus, it suggests that problems within the gestalt can be understood and addressed from a military-centric social work perspective and approach. The situation is so insidious that it requires a call to action from all disciplines but, most important, for the social work profession to take the lead.     

Optimal design of complex experiments with qualitative factors of influence

A complex experiment with qualirarive factors influencing the outcome of the experiment can be seen as a general ANOVA setup. A design of such an experiment will be the assignment at which of the possible levels of the factors the actual experiment should be performed. In this paper optimal designs of such experiments will be characterized with respect to three different optimality criteria including the so called uniform optimality of a design. The possible applications of the main optimization result providing these characterizations can be used to more general experiments. The particular results on these generalizations will be indicated at the end of this paper.     

Estimation of gaussian mixtures with rotationally invariant covariance matrices

Homoscedastic and heteroscedastic Gaussian mixtures differ in the constraints placed on the covariance matrices of the mixture components. A new mixture, called herein a strophoscedastic mixture, is defined by a new constraint, This constraint requires the matrices to be identical under orthogonal trans¬formations, where different transformations are allowed for different matrices. It is shown that the M-step of the EM method for estimating the parameters of strophoscedastic mixtures from sample data is explicitly solvable using singular value decompositions. Consequently, the EM-based maximum likelihood estimation algorithm is as easily implemented for strophoscedastic mixtures as it is for homoscedastic and heteroscedastic mixtures. An example of a “noisy” Archimedian spiral is presented.     

Mobilizing Gender to Promote Peace: The Case of Machsom Watch

The binary model that presents women as peaceful and men as warfaring is a common conception of war and peace. Despite increasing levels of gender equality in most spheres of public life and decreasing gender segregation in institutions in many parts of the world, the associational link of men to war and women to peace remains widespread. Focusing on the Israeli women??s peace organization, Machsom Watch, this article uses a content analysis of interactions between Machsom Watch activists, soldiers and Palestinians to examine how gendered political opportunity structures affect and are affected by interactions between individuals, organizations and institutions. The paper highlights the contradiction between Machsom Watch??s form as a women-only organization and their framing and report language, which is non-gender specific. I argue that this contradiction emerges from their strategic negotiation of the gendered political opportunity structure as well as their culturally bounded experiences of gendered interactions and embodied gender norms. More generally, I argue that by understanding political opportunity structures as being bound by cultural norms that create distinct sets of opportunities and constraints for different groups of people, scholars can better understand the particular manifestation of social movement action and thereby more fully account for human agency in social and political structures. Additionally, this paper encourages social movement scholars to understand social movement framing as both a product of political opportunities and constraints as well as an influence in the formation of the political opportunity structure.
