The aim of this paper is to analyse the welfare consequences of the processes of liberalisation of trade between asymmetric states in terms of the various size sand effectiveness of their economies and the type of international exchange. These characteristics ultimately define the distribution of benefits from the liberalisation of international trade. When it is inter-industry or vertical intra-industry and barriers in trade are smaller than the difference in the effectiveness of the economies, the trade liberalisation undoubtedly contributes to improved social welfare, regardless of the level of effectiveness and the size of the economy. In the situation, however, of horizontal intra-industry trade, changes in the welfares of asymmetric countries, caused by their progressing trade liberalisation, depend on the sizes and effectiveness of their economies. The welfare of society in either a very big and ineffective or in a small and very ineffective country could even decrease in such a situation. This is the case when the increase in consumers’ surplus is not sufficient to compensate for the decreasing profits of firms.

The use of welfare support by EU migrants has dominated media coverage and political debates about EU migration in the UK for several years, regularly featuring claims about the negative effects of the presence of EU migrants on the UK social security system. Such claims became particularly prominent in 2013–2015, during the UK government’s campaign to limit EU migrants’ access to UK welfare benefits and in debates prior to the Brexit referendum. This article sheds light on how Polish migrants position themselves concern-ing the claiming of welfare benefits in the UK and how this affects their welfare strategies. The article is based on 14 qualitative interviews conducted in Liverpool 18 months after the Brexit referendum. Using stigma and benefits stigma as an overall theoretical framework, we find that the informants, in their posi-tioning narratives, 1) put forward similar stigmatising expressions and stereotypes regarding the use of wel-fare as those featured by politicians and the media, which points to perceived abuse; 2) make a distinction between in-work and out-of-work benefits, the first being more acceptable than the second; 3) prefer living on savings or accepting ‘any job’ over making use of out-of-work benefits, which points to an underuse and/or to possible processes of marginalisation; and 4), a tendency among those who have experience with claiming out-of-work benefits to question the discourses of welfare abuse. Finally, ‘working’ and ‘contrib-uting’ to the system as opposed to relying on welfare support is perceived as a precondition to staying in the UK after Brexit – welfare and work are seen to signal very high stakes indeed.

This article, through the prism of immigration policy models proposed by Stephen Castles (1995), Steven Weldon (2005) and Liah Greenfeld (1998), discusses those aspects of Norwegian immigration policy that refer directly to children. Areas such as employment, education, housing and health care influence the situation of an immigrant family, which in turn affects the wellbeing of a child. However, it is the education system and the work of Child Welfare Services that most directly influence a child’s position. Analysis presented in this article is based on the White Paper to the Norwegian Parliament, and data that were obtained in expert interviews and ethnographic observation in Akershus and Buskerud area in Norway, conducted between 2012 and 2014. The article raises the question whether the tools of im-migration policy used by social workers and teachers lead to integration understood as an outcome of a pluralist or individualistic-civic model of immigration policy or are rather aimed at assimilation into Norwegian society, attempting to impose the effect of assimilation or the collectivistic-civic policy model.

The main goal of this article is to compare the opinions of citizens from four European countries (Germany, Great Britain, Spain and Poland) regarding basic income in the broader context, among other things, of welfare regimes these countries represent. Statistical analyses of the Europeans’ attitudes towards basic income are based on interviews carried out in 28 European Union countries. Four countries, representing four different types of welfare regimes that can be found in the literature (the Nordic model has been excluded due to the sample size), and differing in economic welfare as well as historical experiences in regard to socio-economic system formation, have been selected for further analysis. Our analysis is based on special use of the single posthoc test with the Bonferroni adjustment for evaluating cross-country differences in basic income support and use of logistic regression for verifying the within-country impact of particular effects on basic income attitudes. The results of our analysis do not confirm that either the type of welfare regime or the level of social services in particular countries have a significant impact on attitudes toward basic income attitudes. However, we found the clear and direct impact of basic income awareness on supporting the programme.

Introduction: Effective and safe anesthesia for rodents has long been a leading concern among biomedical researchers. Intraperitoneal injection constitutes an alternative to inhalant anesthesia.

Purpose: The aim of this study was to identify a safe, reliable, and effective anesthesia and postoperative analgesia protocol for laboratory rats exposed to painful procedures.

Material and methods: Twenty-seven female Wistar rats in an ongoing study that required surgery were randomized into groups for three different intraperitoneal anesthesia protocols and three different analgesia regimens. The anesthesia groups were (1) medetomidine + ketamine (MK), (2) ketamine + xylacine (KX), and (3) fentanyl + medetomidine (FM). Three analgesia groups were equally distributed among the anesthesia groups: (1) local mepivacaine + oral ibuprofen (MI), (2) oral tramadol + oral ibuprofen (TI), and (3) local tramadol + oral tramadol + oral ibuprofen (TTI). A core was assigned to measure anesthesia (0-3) and analgesia (0-2) effectiveness; the lower the score, the more effective the treatment.

Results: The mean MK score was 0.44 versus 2.00 for FM and 2.33 for KX. Mean score for analgesia on the first postoperative day was TTI (4.66) TI (9.13), and MI (10.14). Mean score 48 hours after surgery was TTI (3.4), TI (6.71), and MI (9.5). These differences were statistically significant.

Conclusion: MK was shown to be a reliable, safe, and effective method of anesthesia. The TTI analgesia regimen is strongly recommended in light of these results.

In this paper a novel non-linear optimization problem is formulated to maximize the social welfare in restructured environment with generalized unified power flow controller (GUPFC). This paper presents a methodology to optimally allocate the reactive power by minimizing voltage deviation at load buses and total transmission power losses so as to maximize the social welfare. The conventional active power generation cost function is modified by combining costs of reactive power generated by the generators, shunt capacitors and total power losses to it. The formulated objectives are optimized individually and simultaneously as multi-objective optimization problem, while satisfying equality, in-equality, practical and device operational constraints. A new optimization method, based on two stage initialization and random distribution processes is proposed to test the effectiveness of the proposed approach on IEEE-30 bus system, and the detailed analysis is carried out.

The analyses and conclusions presented in the article are based on the results of qualitative panel surveys conducted among large indigent families in the years 2013 to 2014 and in 2017. The survey attempted to answer the questions of whether and to what extent the implementation of a pro-family policy in Poland in 2016 influenced the situation of large families receiving institutional social aid. On what do these families spend the payments received from the Family 500+ programme? Has their new economic situation favoured their activation or increased their ability to manage? Could the programme, in consequence, hinder or limit the intergenerational transmission of poverty? The author concludes that in fact the effects of financing large families differ from those that were intended. The programme, which was intended to be pro-natal, has acquired the nature of social aid payments. It has improved the material situation of many families, but it has not sufficiently contributed to changing ways of thinking about the children’s futures, which would contribute to limiting the processes of inheriting poverty.
