Interval shrinkage estimators

This paper considers estimation of an unknown distribution parameter in situations where we believe that the parameter belongs to a finite interval. We propose for such situations an interval shrinkage approach which combines in a coherent way an unbiased conventional estimator and non-sample information about the range of plausible parameter values. The approach is based on an infeasible interval shrinkage estimator which uniformly dominates the underlying conventional estimator with respect to the mean square error criterion. This infeasible estimator allows us to obtain useful feasible counterparts. The properties of these feasible interval shrinkage estimators are illustrated both in a simulation study and in empirical examples.     

Maintenance of submersible pumps in the septic tanks: ergonomic and biological risks to the worker

In this study was observed the maintenance task of submersible pumps septic tanks installed in industrial bathrooms. This maintenance activity operators are exposed to various biological and ergonomic risks. This type of activity requires its great physical performers who are also subject to contact with human waste in the form of liquids, gases and solids. Besides the problems mentioned, are still exposed to high temperatures that can cause diseases such as hyperthermia or heatstroke. These aspects were observed using the ergonomic assessment methodology in order to suggest improvements that are reflected in productivity and employee satisfaction.     

On the educational edges of a learning society: the Finnish hinterland as a framework of educational choices for young people

In this article, we examine the school-going and educational choices of youth living in sparsely populated regions of Finland that are located far away from educational institutions. We ask the following question: What kind of concrete impact does the geographic narrowing of educational possibilities have on the lives of youth in remote villages? Thirty-five interviewees (15 boys and 20 girls) between the ages of 14 and 18 were selected for this analysis. According to the results, gender and families’ symbolic resources are still strong predictors of youth’s educational choices; however, in the Finnish hinterland, families’ economic resources become a significant reflection of young people’s realistic educational possibilities. The youth in our analysis can be seen as ‘others’ of the contemporary educational and regional policies – that is, members of a learning society who are living in an educational vacuum and are forced to create their educational paths by making numerous compromises and forgetting many of their personal dreams. Their situation is not unique, as Finland’s wide-ranging neoliberal centralisation policies tend to create educational vacuums in certain regions on the edges of society.     

Unionization in the American Newsroom, 1930 to 1960

This study of the material benefits brought to American news workers from the 1930s through the 1960s builds on previous work by media labor‐studies scholars such as Bonnie Brennen, Daniel Leab, Phillip Glende and Sam Kuczun, among others, who have examined the history of the American Newspaper Guild (ANG) in great detail. Their work has focused on legal and policy developments under the Roosevelt administration and in U.S. labor law. My study, as part of a larger project, looks at some of the ground‐level impacts of unionization. It does so examining Editor & Publisher, The Quill and The Guild Reporter, among other publications, and references to the material benefits in pay, time off, work‐life balance, health insurance, job security and other, practical and positive ancillary effects brought by the uneven unionization of the newsroom. The arrival of white‐collar unions for new workers was not a panacea to their problems. But it did help them in their collective quest in the United States during the interwar and then post‐World War Two‐eras for better working conditions and a firmer sense of their professionalized identity.     

SELECTIVE RECOGNITION: HOW TO RECOGNIZE DONORS TO INCREASE CHARITABLE GIVING

Recognizing donors by revealing their identities is important for increasing charitable giving. Using a framed field experiment, we show that all forms of recognition that we examine increase donations relative to the baseline treatment, and recognizing only the highest or only the lowest donors has the strongest and significant effect. We argue that selective recognition creates tournament‐like incentives. Recognizing the highest donors activates the desire to seek a “positive prize” of prestige, while recognizing the lowest donors activates the desire to avoid a “negative prize” of shame. We discuss how selective recognition can be used by charities to increase donations. (JEL C93, D64)     

Multiple Monte Carlo testing,with applications in spatial point processes

The rank envelope test (Myllymäki et al. in J R Stat Soc B, doi: 10.1111/rssb.12172, 2016) is proposed as a solution to the multiple testing problem for Monte Carlo tests. Three different situations are recognized: (1) a few univariate Monte Carlo tests, (2) a Monte Carlo test with a function as the test statistic, (3) several Monte Carlo tests with functions as test statistics. The rank test has correct (global) type I error in each case and it is accompanied with a p-value and with a graphical interpretation which determines subtests and distances of the used test function(s) which lead to the rejection at the prescribed significance level of the test. Examples of null hypotheses from point process and random set statistics are used to demonstrate the strength of the rank envelope test. The examples include goodness-of-fit test with several test functions, goodness-of-fit test for a group of point patterns, test of dependence of components in a multi-type point pattern, and test of the Boolean assumption for random closed sets. A power comparison to the classical multiple testing procedures is given.     

Negotiating motherhood: women with troubled upbringings and their self‐conceptions as mothers

This paper examines how women who experienced severe adjustment problems during adolescence, and who had troubled childhoods in families with high levels of conflict, construct their self‐conceptions as mothers. Applying data from a 30‐year‐long follow‐up study, this paper examines how participants with troubled upbringings experience social norms of motherhood. Two overall themes emerged along with their associated subcategories, and these are identified as significant findings. The first theme is the stigmatizing gaze, exemplifying how the intervention of the child welfare service is recognized as essential to the women's self‐conception; its three subcategories are prejudiced motherhood, predestined motherhood and self‐critical motherhood. The second theme is significant relationships, exemplifying the mothers' personal bonds and contributing greatly to their self‐conception; its three subcategories are the other half, next of kin and disturbed relations. The findings reveal that the way these women view themselves as mothers cannot be separated from the way that others view them, and in addition, they must negotiate their positions as mothers through the normative discourses of motherhood. The findings apply to both theoretical and practical social work, addressing the need for an understanding of motherhood within the field of child welfare.     

Jewish fearless speech: towards a definition of Soviet Jewish nonconformism

ABSTRACT

The article proposes a model for analyzing the utterances of Jewish nonconformism in the late-Soviet Russian literature, based on Michel Foucault’s theory of fearless speech and Eric Gans’ theory of the origins of culture. The utterances of nonconformism transform an asymmetrical conflict into symmetrical nonvictimary relations, in which a new, supposedly real identity of a figure is revealed and mobilized for protest. These new relations are based on mutual recodification of different discursive configurations – political, moral, social, aesthetical, metaphysical, or mystical. The discussion will focus on the selected novels of Fridrikh Gorenshtein, Felix Roziner, and, in greater detail, David Shrayer-Petrov.
