Changing symbolic and geographical boundaries between penal zones and rural communities in the Russian Federation

The article examines the processes involved in the integration of the USSR's secret places into mainstream rural society in the Russian Federation. Taking the example of one rural district in the Volga-Ural region that has been the site of a large prison complex over a period of ninety years, the article examines how economic changes and local government and penal reforms have eroded the boundary that marked off the penal region from the rural district in which it was located. Using interviews and social surveys conducted among the local population, the article examines the extent to which the opening of the penal sub-region has led to changes in the symbolic boundary between the communities in the rural raion. The article concludes that although new spaces of active government are being produced in rural Russia, these are not necessarily the basis for the emergence of new common identities among the people living in them.     

x~n+1在有理数域上的因式分解

从特殊情况研究多项式f(x)=xn+1在有理数域上的因式分解.对于正整数,设H(n)是n的大于1的奇约数的个数.本文用初等数论和近世代数的知识证明了:多项式xn+1在有理数域上可分解为H(n)+1个不可约因式的乘积,即D(f)=H(n)+1.     

Do military veteran and civilian students function differently in college?

Objective: The authors sought to assess military veterans' functioning in college by comparing their experience with that of civilian students. Participants: The study, conducted from April 2012 to February 2013, included 445 civilian and 61 student service member/veteran (SSM/V) undergraduates, drawn from a community college and two 4-year Catholic colleges, in Pennsylvania, New Jersey, and New York. Methods: Participants completed anonymous online surveys. Six areas of functioning in transition to college were examined: Health, Fitting In, Emotional Adjustment, Productivity, Perceived Career Support, and Social Engagement. Results: Students, both SSM/V and civilian, with past exposure to a potentially traumatic event fit in worse than students without such exposure. Past exposure to trauma was associated with poorer emotional adjustment in civilian students, but not in SSM/V. Conclusions: Implications of results were discussed.

On square ordinal contingency tables: a comparison of social class and income mobility for the same individuals

Summary.  Square contingency tables with matching ordinal rows and columns arise in particular as empirical transition matrices and the paper considers these in the context of social class and income mobility tables. Such tables relate the socio-economic position of parents to the socio-economic position of their child in adulthood. The level of association between parental and child socio-economic position is taken as a measure of mobility. Several approaches to analysis are described and illustrated by UK data in which interest focuses on comparisons of social class and income mobility tables that are derived from the same individuals. Account is taken of the use of the same individuals in the two tables. Additionally comparisons over time are considered.

Extreme statistics from the cosine distribution

The cosine distribution serves as a very good teaching example for which exact moment properties of extreme order statistics can be expressed in terms of elementary functions. This article presents the limiting joint distribution of the extreme order statistics for the cosine distribution. It is shown that burrows'(1986) result is a special case of the result presented in this article.

Lattice path combinatorics for multiple product identities

Lattice paths are enumerated as walks on a lattice under the Delannoy criterion of vertical, horizontal and upward diagonal steps. Delannoy recursions are generalized for arbitrary weights in each of these directions, where the row elements of the Delannoy triangles correspond to lattice paths for all walks at a given length.     

Estimation on Varying-Coefficient Partially Linear Model With Different Smoothing Variables

The authors give the estimation on the varying-coefficient partially linear regression model with different smoothing variables. The efficient estimators of the intercept function and the coefficient functions are obtained by a one-step back-fitting technique based on their initial estimators given by local linear technique and the averaged method. Furthermore, their asymptotic normalities are given. Some simulation studies are used to illustrate the performances of the estimation.
