The permutation flow shop problem with blocking. A tabu search approach

This paper develops a fast tabu search algorithm to minimize makespan in a flow shop problem with blocking. Some properties of the problem associated with the blocks of jobs have been presented and discussed. These properties allow us to propose a specific neighbourhood of algorithms. Also, the multimoves are used that consist in performing several moves simultaneously in a single iteration and guide the search process to more promising areas of the solutions space, where good solutions can be found. It allow us to accelerate the convergence of the algorithm. Besides, a dynamic tabu list is proposed that assists additionally to avoid being trapped at a local optimum. The proposed algorithms are empirically evaluated and found to be relatively more effective in finding better solutions than attained by the leading approaches in a much shorter time. The presented ideas can be applied in many local search procedures.     

Neyman-type sample allocation for domains-efficient estimation in multistage sampling

We consider a problem of allocation of a sample in two- and three-stage sampling. We seek allocation which is both multi-domain and population efficient. Choudhry et al. (Survey Methods 38(1):23–29, 2012) recently considered such problem for one-stage stratified simple random sampling without replacement in domains. Their approach was through minimization of the sample size under constraints on relative variances in all domains and on the overall relative variance. To attain this goal, they used nonlinear programming. Alternatively, we minimize here the relative variances in all domains (controlling them through given priority weights) as well as the overall relative variance under constraints imposed on total (expected) cost. We consider several two- and three-stage sampling schemes. Our aim is to shed some light on the analytic structure of solutions rather than in deriving a purely numerical tool for sample allocation. To this end, we develop the eigenproblem methodology introduced in optimal allocation problems in Niemiro and Wesołowski (Appl Math 28:73–82, 2001) and recently updated in Wesołowski and Wieczorkowski (Commun Stat Theory Methods 46(5):2212–2231, 2017) by taking under account several new sampling schemes and, more importantly, by the (single) total expected variable cost constraint. Such approach allows for solutions which are direct generalization of the Neyman-type allocation. The structure of the solution is deciphered from the explicit allocation formulas given in terms of an eigenvector \({\underline{v}}^*\) of a population-based matrix \(\mathbf{D}\). The solution we provide can be viewed as a multi-domain version of the Neyman-type allocation in multistage stratified SRSWOR schemes.

     

Biochemical markers of bone metabolism in healthy elderly men. The relationship to physical activity

The purpose of the present study was to examine the serum levels of bone turnover markers and interleukin 1β in healthy elderly men with different levels of habitual physical activity. The study was conducted on 40 healthy men aged between 65 and 85 years (mean 74.0?±?7.55 years). The study population was divided into two groups with respect to the level of physical activity: 22 less active subjects (energy expenditure related to physical activity below 1600?kcal per week) and 18 more active subjects (above 1600?kcal per week). To estimate the physical activity of the study population, weekly energy expenditure was measured in each subject with use of Caltrac accelerometer. In the blood serum levels of bone formation marker – osteocalcin and resorption marker – the C-terminal telopeptide of collagen I (ICTP), and interleukin-1β were determined. Concentrations of osteocalcin and ICTP in less active subjects were significantly higher (by 3.62?ng/ml and by 1.21?μg/l respectively, p?<?0.05), reflecting the higher bone turnover in comparison to values determined in more active subjects. Positive correlations between ICTP and osteocalcin levels (r?=?0.5814 and r?=?0.6526; p?<?0.05), and between ICTP and IL-1β (r?=?0.5823 and r =?0.6040; p?<?0.05) in less and more active men were found. On the ground of the presented study it can be concluded that the decreased bone turnover occurred in men with higher level of habitual physical activity. This study showed the relationship between serum level of IL-1β and bone resorption but the habitual physical activity has no effect on this cytokine activity.     

Reproductive rights or duties? The rhetoric of division in social media debates on abortion law in Poland

ABSTRACT

This study explores the argumentative schemas used in claim-making and the rhetorical resources for stance-taking in the online abortion law debate in Poland in late 2016. It shows how these discursive devices were used to divide and discredit the opponent in the social media by two social movements: the Stop Abortion coalition of conservative and religious organizations that sponsored the legislative proposal to considerably restrict abortion, and the Save Women committee that stood behind the ‘black’ protests opposing the project. The textual material is drawn from social media profiles of the two movements following a week of intense street protests and publicity activities (19–26 October 2016). It is subjected to contrastive argument analysis and critical discourse analysis of rhetorical resources. The analysis involves comparing (1) the discrepant premises underpinning arguments in the process of claim-making; (2) the reverse distribution of legitimization techniques deployed; and (3) the choices of name-calling devices aimed at discrediting antagonists.     

Proud to be a woman: Womanhood,old age,and emotions

ABSTRACT

This article takes its starting point in the discussions regarding intersecting discourses of gender and age and the lived experience of older women. The main objective is to discuss the experience of womanhood among older women and to demonstrate their active role in creating spaces for themselves and their friends and affecting each other. The study is based on narrative interviews with female members of the University of the Third Age (U3A). The main findings describe older women who actively engage with discourses of gender to embark on positive constructions of womanhood. They create their own spaces for women’s activism that are filled with positive emotions mobilized to support each other. This article discusses such findings and their relevance to the study of old age and gender. As a result, it serves as an invitation to think and feel differently about older women and their experience of womanhood.
