Women on strike: mobilizing against reproductive injustice in Poland

The paper employs a lens of reproductive justice (RJ) to discuss the events of the 2016 mobilization against a total abortion ban proposal in Poland. By presenting the context of women’s rights in Poland, especially the abortion debates, we argue that the 2016 Women’s Strike showed that taking a stand for reproductive justice was countered by governmental actions. By using a case study approach, the paper analyzes the Strike as a tumultuous act of women’s solidarity while simultaneously assessing its implications for RJ issues. We discuss the aftermath and the socio-political reticence to acknowledge the complexities of women’s lives and reproductive choices. Further, we provide arguments for applying the RJ framework into discerning the notion of ideal citizens and gendered social control in Poland. This localized analysis has a global relevance by reflecting the impact of worldwide trends in women’s rights activism and RJ in the context of resurfacing nationalisms and populism.     

Does Consumer Confidence Forecast Household Saving and Borrowing Behavior? Evidence for Poland

Consumer confidence plays an important role in households’ decision-making processes. This study investigates the effects of consumer confidence on household saving and borrowing behavior that are unsatisfactorily considered in previous discussions. The questions of interest are first, whether indexes of consumer confidence have any predictive power on their own for future household saving and borrowing rates, and second, whether they contain information about future household saving and borrowing rates aside from the information contained in other available indicators. In addition to aggregate confidence indicators, their components are used to provide more precise information. Overall, the multiple linear regression analysis (OLS technique) of Polish time-series data gives positive answers to both questions. This finding supports the recommendation of combining the strengths of objective indicators (such as economic fundamentals) and subjective indicators (such as consumer confidence) to improve household financial behavior forecasts.     

Packing <Emphasis Type="Bold">[1, Δ]</Emphasis>-factors in graphs of small degree

Given an undirected, connected graph G with maximum degree Δ, we introduce the concept of a [1, Δ]-factor k-packing in G, defined as a set of k edge-disjoint subgraphs of G such that every vertex of G has an incident edge in at least one subgraph. The problem of deciding whether a graph admits a [1,Δ]-factor k-packing is shown to be solvable in linear time for k = 2, but NP-complete for all k≥ 3. For k = 2, the optimisation problem of minimising the total number of edges of the subgraphs of the packing is NP-hard even when restricted to subcubic planar graphs, but can in general be approximated within a factor of by reduction to the Maximum 2-Edge-Colorable Subgraph problem. Finally, we discuss implications of the obtained results for the problem of fault-tolerant guarding of a grid, which provides the main motivation for research.     

Management innovation,pro-innovation organisational culture and enterprise performance: testing the mediation effect

The interest in management innovation (MI) is growing and the conviction about its significant role in boosting an enterprise’s competitive advantage and performance has recently gained ground. The studies on MI and its relationships with enterprise performance, which are relatively scarce in literature, indicate the complexity of these relationships. This inspired us to propose the management innovation construct and its operationalisation, which allowed for the empirical verification of the relationships between management innovation and enterprise performance. Simultaneously, we adopted the hypothesis on the mediating role of pro-innovation organisational culture. The aim of this article, therefore, is to study the relationships between MI and enterprise performance as well as to determine what role is played by pro-innovation organisational culture in these relationships. In order to do that, we conducted a survey of 301 companies based in Poland. Our research results confirmed the existence of relationships between management innovation and enterprise performance in the survey sample, although they were not very strong. Additionally, the hypothesis about the mediating role of organisational culture was also partially supported. The results of our study enrich the knowledge about the role of MI in stimulating enterprise performance and the role of pro-innovation organisational culture. We also discuss the implications for further research and management practice.     

The “ugly” face of social investment? The politics of childcare in Central and Eastern Europe

In this article, we aim to understand the development dynamics of a specific area of social investment (SI), that is, childcare policies, in the context of postcommunist politics and the recent right-wing turn that took place in the Czech Republic, Hungary, and Poland. This article identifies varieties of channels for promoting SI. First, in taking the perspective of the “mixed economy of welfare,” we argue that attempts made to introduce elements of SI to the childcare policies involved various leading roles available for either the private sector or state/public domain. Second, it is important to distinguish between implicit/unintended and explicit/intended projects both in relation to cases in which SI strategy is applied via marketization/privatization and when it involves a government-led project. Third, we take into account the politics of SI implementation that might involve applying certain principles central to policy concepts (such as “investment”) in justifying policy instruments incompatible with original ideas. Although arguments about SI have been extensively used by Eastern European leaders, their goal has been to justify welfare reforms that were implicitly or explicitly directed towards the middle class while excluding the “nondeserving” often based on ethnic identity. We characterize Poland as a case of “implicit marketization,” the Czech Republic as a case of “explicit privatization,” and the Hungarian version of SI as a case of “explicit public dualization.” In this, we show that in some cases, the implementation of SI approaches by right-wing populist parties might rear its “ugly” head.     

Data-Driven Tests for Trend

This article proposes a new nonparametric test for the ordered alternatives problem in the k-sample setting for null hypothesis of lack of trend. This article further elaborates upon and extends the results of Ledwina and Wy?upek (2012a Ledwina , T. , Wy?upek , G. ( 2012a ). Two-sample test against one-sided alternatives . Scand. J. Statist. 39 : 358 – 381 .[Crossref], [Web of Science ®] , [Google Scholar]) obtained for k = 2. Simulations show that the new test has high and stable power and is able to control the Type I error to satisfactory extent, thus solving the problem posed in Terpstra and Magel (2003 Terpstra , J. T. , Magel , R. C. ( 2003 ). A new nonparametric test for the ordered alternative problem . J. Nonparametr. Statist. 15 : 289 – 301 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). Our theoretical results say that asymptotic errors of both kinds do not exceed significance level, thus implying that the test is asymptotically unbiased.     

Circadian rhythm of hot flashes and activity levels among prostate cancer patients on androgen deprivation therapy

Abstract

Background: Modifiable risk factors contribute to the pathogenesis of cardiovascular disease (CVD) and erectile dysfunction (ED). We aimed to compare the knowledge about the contribution of modifiable risk factors to the pathogenesis of CVD and ED. The impact of patients’ having modifiable risk factors on the awareness of their negative influence on the development of CVD and ED was examined.

Methods: To this multicenter cohort study, we included 417 patients with CHD who had been hospitalized in the cardiology or cardiac surgery department during the previous six weeks and underwent cardiac rehabilitation in one of the five centers. Knowledge about modifiable risk factors was collected. ED was assessed by an abridged IIEF-5 questionnaire. Comparisons between groups were conducted using the Student’s t-test, Mann–Whitney U test, and Kruskal–Wallis test. Relationships were analyzed with Spearman's rank correlation coefficient.

Results: The mean number of correctly identified risk factors for CVD was significantly higher than those for ED (3.71?±?1.87 vs. 2.00?±?1.94; p?<?.0001). Smoking was the most recognized risk factor both for CVD and ED. Dyslipidemia was least frequently identified as a risk factor for CVD. Sedentary lifestyle was the only risk factor whose incidence did not affect the level of patient knowledge.

Conclusions: Cardiac patients with ED know more about risk factors for CVD than ED. It is necessary to include information about the negative impact of modifiable risk factors on sexual health into education programs promoting healthy lifestyles in men with cardiovascular diseases.     

Some methods for constructing C-designs

Block designs having a property described by Caliński (1971) and Saha (1976), referred to as C-property, are further considered. A necessary and sufficient condition for a block design to have the C-property is given by Saha (1976) and another by Ceranka and Koz?owska (1983). In this paper some methods for constructing such block designs are presented.     

Anxiety and social stress related to adolescent gambling behaviour

Abstract

This study examined the relationship between anxiety, social stress, and gambling behaviour among 1,044 high school students in grades 7 to 11. Adolescents completed questionnaires concerning their state, trait, and generalised anxiety, social stress, and gambling behaviour. Results reveal that adolescent probable pathological gamblers report more state anxiety, trait anxiety, and higher levels of social stress compared to non‐gamblers, social gamblers, and gamblers at‐risk for serious problems. Gamblers with high state and trait anxiety engaged in more severe gambling behaviours, greater substance abuse, reported different reasons for gambling, and endorsed more dissociation items. The results provide additional support for Jacobs’ (1986) General Theory of Addictions. The implications for treatment and prevention programs are discussed.
