Facing arrhythmia. Reconstructing time in the pandemic by the metropolitan creative classes in Poland

This paper shows how the metropolitan creative classes in Poland reacted to the changes in the organization of everyday life caused by the COVID-19 pandemic, especially its temporality and rhythmicity. The pandemic and lockdowns reorganized previous ways of experiencing and managing time. Based on our empirical research and research by other scholars, we have identified some of the most common disruptions of pandemic temporality. However, a vital element of the article is to specify how the social category we studied dealt with these disruptions. In doing so, we show that the response to the breakdown of the previous order of everyday life was to restore a sense of stability actively. We were also interested in the possible, also negative consequences of the findings for the social category under study. The empirical basis for the article are in-depth interviews conducted during the fourth phase of the ongoing research project [title anonymized], which began during the first weeks of the lockdown in Poland.     

Is Gender Mainstreaming Viable? Empirical Analysis of the Practicality of Policies for Agriculture-Based Gendered Development in Ethiopia

Gender mainstreaming is a global strategy to ensure gender-equality in agriculture and other economic sectors. However, the operationalization of gender mainstreaming is often contested in the global south. Using a concurrent mixed method design, this study investigates if the gender mainstreaming narratives embedded in agricultural extension and food security policies in Ethiopia are practical for improving agriculture-based gendered development among smallholder users of climate-smart agricultural technologies. Results demonstrate that women smallholders’ needs that are essential to the use of agricultural technologies are overlooked. Despite they are “users” of agricultural technologies; women’s access to agricultural inputs and extension services is restricted. There is a lack of synchronized activities and strategies to guide the implementation of gender mainstreaming, as well as separate gender budgets to address gendered agricultural problems. Increasing agricultural production is a national policy goal, although gender equality in production growth is not a key priority in the implementations of agricultural policies. Although improvement in the institutionalization and implementation of the GAD approach for addressing strategic gender needs is a priority in gender mainstreaming, an interchangeable and concurrent institutionalization and implementation of the Women in Development approach for addressing practical gender needs and the Women Culture and Development approach for addressing constraints that emanate from the multiple realities and identities of women are also required. Identifying and addressing the practical gender needs of women and problems that emanate from their multiple identities and realities are essential prerequisites for the practicality of gender mainstreaming for gender equality in agricultural development. Furthermore, there is a need to design and implement locally specific gender-mainstreaming strategies that address the distinct needs of women smallholders, as well as separate gender budgets to reach local contexts.     

On the problem of the unique characterization of discrete distributions by single regression of weak records

We consider the problem of the unique identification of discrete probability distributions by the single regression function of non-adjacent discrete weak record values. We present a new approach to this problem and we show that the uniqueness of the characterization is equivalent to the uniqueness of solution to a corresponding difference equation or an appropriate system of difference equations. This result is applied to obtain known as well as new characterizations of discrete distributions.     

Uniqueness of characterization of absolutely continuous distributions by regressions of generalized order statistics

We provide a new approach to the problem of the unique identification of distributions with a continuous density by a single regression function of order statistics or record values or, more generally, generalized order statistics. Using their Markov property we show that the characterization is unique if and only if the corresponding system of differential equations has the unique solution. This result is new even in the particular case of ordinary order statistics. This approach provides a new proof of characterization of power, exponential and Pareto distributions by linearity of corresponding regression. It also yields new examples of characterizations of distributions.     

Comment on stephen M. Wunker, ‘The promise of non-profits in Poland and Hungary: an analysis of third sector renaissance’

Both the pre-war tradition and the real socialist system have influenced the form of the non-profit sector emerging in Poland. In as much as the pre-war traditions are continued by the church charities, lay institutions are established on the basis of state structures in the form of specific non-profit organisations subsidised to a large extent by the state (the so-called non-profit social institutions). Perhaps in this way partnership relations will develop between the government and nonprofit organisations which will continue to expand. The stage through which Poland is currently passing means that a coherent system of non-profit organisations has not yet developed and, what is more, it is seldom called a voluntary or third sector. The only formalised institutions are foundations and associations. It is evidently necessary to fill the gap in social service provision caused by government and market failures, and we may cherish a hope that such a system of non-profit organisations providing services to those in most need will soon be created in Poland.     

Quadratic subspaces and construction of Bayes invariant quadratic estimators of variance components in mixed linear models

Gnot et al. (J Statist Plann Inference 30(1):223–236, 1992) have presented the formulae for computing Bayes invariant quadratic estimators of variance components in normal mixed linear models of the form where the matrices V _i , 1 ≤ i ≤ k − 1, are symmetric and nonnegative definite and V _k is an identity matrix. These formulae involve a basis of a quadratic subspace containing MV ₁ M,...,MV _k-1 M,M, where M is an orthogonal projector on the null space of X′. In the paper we discuss methods of construction of such a basis. We survey Malley’s algorithms for finding the smallest quadratic subspace including a given set of symmetric matrices of the same order and propose some modifications of these algorithms. We also consider a class of matrices sharing some of the symmetries common to MV ₁ M,...,MV _k-1 M,M. We show that the matrices from this class constitute a quadratic subspace and describe its explicit basis, which can be directly used for computing Bayes invariant quadratic estimators of variance components. This basis can be also used for improving the efficiency of Malley’s algorithms when applied to finding a basis of the smallest quadratic subspace containing the matrices MV ₁ M,...,MV _k-1 M,M. Finally, we present the results of a numerical experiment which confirm the potential usefulness of the proposed methods. Dedicated to the memory of Professor Stanisław Gnot.
