Published: March 2021

Objective: This study aims to explore the relationship between widowhood and social participation on life satisfaction of
the elderly in rural China. Methods: We used questionnaires and scales to investigate 322 rural elderly people in Shaanxi Province.
Results: We found that widowhood was negatively correlated with social participation (P = 0.033). Widowhood was negatively
correlated with life satisfaction (P = 0.007). Social activities play a mediating role between widowhood and life satisfaction.
Conclusion: Widowhood directly affects the life satisfaction of the elderly, and widowhood affects the life satisfaction of the
elderly through social activities. More participation in social activities is an effective way to improve the life satisfaction of the
elderly.

Zerdüştîlik Yeniden Canlanıyor mu? (Kuzey Irak’ta Ortaya Çıkan Yeni Zerdüştî Hareket Üzerine Bir Araştırma)
Authors: SULAR Mehmet Emin
Published: March 2021

20. yüzyıldan itibaren Celadet ve Kamuran Ali Bedirhan gibi seküler milliyetçi Kürt aydınlar, Kürtlerin Medlerden geldikleri, İslam öncesi dinlerinin Zerdüştîlik olduğunu iddia etmişlerdir. Bu iddialar gelişen Kürt milliyetçiliğine bağlı olarak Kürtler için şanlı tarih, kadîm bir din oluşturmayı amaçlamıştır. Söylemler zamanla, bazı okur-yazar kesim arasında da karşılık bulmuştur. 2012 yılında İsveç-Stockholm’da Andez Hawezi dine yeni giren taraftarlarıyla bir Zerdüştî tapınağı kurmuştur. Onun desteği ve yurt dışından dönenlerle Kuzey Irak’ta Zerdüştîliğe geçişte bir hareketlilik başlamıştır. 2014’te DEAŞ’ın saldırıları, geçişleri daha da hızlandırmış ve yeni bir Zerdüştî Hareket ortaya çıkmıştır.Yeni Zerdüştî Hareket, çıkışından kısa süre sonra Pîr Lokman ve Yesna Grubu şeklinde ikiye bölünmüştür. Çalışmanın amacı Yeni Zerdüştî Hareket hakkında bilgi verdikten sonra iki grubu ayrı ayrı incelemektir. Araştırma için alan çalışması yapılmış ayrıca yazılı-görsel veri sağlayan kitap, makale ve dijital kaynaklardan faydalanılmıştır.
European Union-Canada Relations: Cooperation, Disputes and Prospects
Authors: SÜLÜN Dilara , YILDIZ Uğur Burç , ÇAMYAMAÇ Anil
Published: March 2021

This paper aims to analyze European Union-Canada relations that have significantly enhanced in the last decade. Economic and security relations between the European Union and Canada have considerably improved in the last decade particularly after the conclusion of the Comprehensive Economic and Trade Agreement and the Strategic Partnership Agreement, which are also milestones that would govern the parties’ long-term relations. Despite a territorial dispute between Canada and Denmark regarding Hans Island, and Canada’s on-going opposition to the European Union’s Arctic Council membership, these frictions are not significant enough to jeopardize the current progress in relations, as analyzed in this paper. As long as both sides continue their powerful commitment to liberal democracy, free market economy and multilateralism, their cooperation is likely to intensify in the 21st century in the face of international economic and security problems.

The footballisation of the polish sociology of sport
Authors: Stempień Jakub Ryszard
Published: March 2021

The article addresses the issue of the unique position of football among sports, which supports Bromberger’s thesis on the footballisation of society. As an overview of publications shows, football has occupied a special place in the international sociology of sport over the last 30 years; studies of football have been among the twenty most popular topics within the sub-discipline. However, it would be unjustified to speak of the footballisation of the international sociology of sport, understood as the overrepresentation of football in this sub-discipline. The situation is different when it comes to the Polish sociology of sport, where up to 50% of publications in the first fifteen years of the 21st century tackled various football-related issues. In conclusion, theses concerning possible consequences of the footballisation of the Polish sociology of sport are presented, including the type I and type II errors.

Uma Corporeidade para a Naturologia: problematizações e possibilidades
Authors: Gouveia Luana Boffo , Di Pietro Nicole Cerulio , Leite-Mor Ana Cláudia Moraes Barros
Published: March 2021

Neste artigo pretende-se refletir, apoiado na bibliografia “Uma Feno-menologia do Corpo” e “Corporeidades: Inspirações Merleau-Pontia-nas...” da autora Terezinha Petrucia da Nóbrega, acerca de novas pos-sibilidades para a concepção de corpo no campo de saber da naturo-logia. OBJETIVO: Objetivamos apontar e ampliar o fazer e o saber corpóreo e sensível na naturologia, de forma a não reproduzirmos as concepções de corpo reducionistas ou dualistas ora vigentes no cam-po da saúde. MÉTODO: trata-se de uma pesquisa bibliográfica teóri-ca-reflexiva, desenvolvida através de leitura sistemática e em profun-didade da literatura da autora e de levantamento de artigos e pesqui-sas que trabalharam noções, técnicas e abordagens do corpo na natu-rologia. RESULTADOS/DISCUSSÃO: nas publicações da naturologia nos deparamos com compreensões sobre o corpo que perpetuam seu aspecto instrumental e biologizante, na qual o corpo se mostra mero receptáculo passível de aplicação de técnicas e ferramentas terapêuti-cas. A teoria da corporeidade proposta por Nóbrega nos permite con-siderar a fenomenologia do corpo, a experiência vivida, a estesia, e suas relações com o processo de conhecimento. CONSIDERAÇÕES FINAIS: sugere-se o aprofundamento dos estudos na literatura da au-tora, perspectiva fenomenológica de Merleau-Ponty e de seus interlo-cutores, que consideramos essenciais para aprofundarmos a reflexivi-dade acerca do corpo e da corporeidade de forma a evitar o risco de a naturologia reproduzir os padrões instrumentalizadores do corpo, no campo da saúde.
Kínai és indiai transznacionális vállalatok befektetései Magyarországon

Published: March 2021

A tanulmány célja, hogy megvizsgálja a kínai és indiai vállalatok magyarországi befektetéseit, azok fő jellemzőit és a magyar kormány ún. „Keleti nyitás” politikájának szerepét e beruházások alakulásában. A szerző a két ázsiai óriásgazdaságból származó befektetések ágazati megoszlásával, piacra lépésük módjával és motivációival foglalkozik. Mindkét ország vállalatai számára az autóipar a legvonzóbb ágazat, de a kínaiak szívesen fektetnek be az információ- és kommunikációtechnológiai (information and communications technology, ICT) termékgyártó (elektronikai) és ­szolgáltató, illetve a megújulóenergia-ágazatokba is, az indiaiak pedig az információtechnológiai (information technology, IT) és az üzletifolyamat-kiszervezési (business process outsourcing, BPO) szolgáltatásokba, valamint a vegyiparba. Elsősorban zöldmezős beruházások vagy felvásárlások útján lépnek be a magyar piacra, és dominánsak a piac-, illetve stratégiaieszköz-kereső motivációik. 2010 után a Keleti nyitás politika pozitívan befolyásolta számos Magyarországra „újonnan érkező” kínai és indiai befektető lokációválasztását, illetve a hazánkban már letelepedettek bővítő beruházásait.

Authors: Moreno Gené Josep
Published: March 2021

Una de las cuestiones más conflictivas que plantea el contrato predoctoral es la de determinar si a la finalización del mismo los investigadores que lo han sus­crito tienen o no derecho a percibir indemnización alguna. Frustrada la posibi­lidad de dotar de indemnización por finalización de contrato a estos supuestos en base a la normativa comunitaria, se plantea la posibilidad de reclamar una indemnización en base a la normativa nacional y, en particular, al art. 49.1.c) ET, que prevé que a la finalización del contrato, excepto en los casos del con­trato de interinidad y de los contratos formativos, el trabajador tendrá derecho a recibir una indemnización equivalente a doce días de salario por año de servi­cios. Pues bien, es en este punto donde se incardinan sendas sentencias del TSJ de Asturias de 23 y 30 de junio de 2020 objeto de este comentario que abordan específicamente esta cuestión, con la particularidad añadida de que, en este su­puesto, el derecho a percibir una indemnización por finalización del contrato, en concreto, de nueve días de salario por año de servicios, se encuentra prevista de un modo expreso en el propio contrato de trabajo.

На троне и на Мавзолее. Женщина и власть в новых российских исторических сериалах
Authors:   University of Tampere, Savkina I. L.
Published: March 2021

This essay explores issues of gender and power in three recent Russian TV series: the first two, “Catherine” (2014–2019) and “The Great” (2015) feature the empress Catherine the Second as a protagonist, while a third, “Fourtseva. The Legend of Catherine” (2011) tells the story of the high-level Soviet official Ekaterina Fourtseva. The producers of these shows have a contradictory task: they seek to strengthen patriarchal stereotypes of femininity through the character of a female monarch while at the same time keeping intact the concept of strong imperial power. Thus, they ‘divide’ their heroine into Catherine-the-female, who had to sacrifice her feminine maternal essence, and Catherine the Great, the empress and the conqueror. The series about ‘Catherine the Third’, as Fourtseva was sometime called, treats the issue of gender and power in a more straightforward way, suggesting that a woman in high power is out of place: doomed to marginality and ‘secondary’ roles, she, at the same time, has no chance of finding happiness as a woman. Differences between the series notwithstanding, none of them question the masculine nature of political power, to which a woman can accede only on the basis of luck or as a sad exception.

The article contains important conceptual conclusions on the problems of the realistic novel of the 19th century and the postmodern novel of the 20th centuries, defines the peculiarities of the traditions of F.M. Dostoevsky and J. Fowles. The presented work provides an opportunity to take a fresh look at the cult works written in the 19th–20th centuries. F.M. Dostoevsky as the “founder” of neo-mythological consciousness — the cultural paradigm of the 20th century — gave J. Fowles valuable “tips” against the background of modern literary thought and his comparison with the mythopoetic thought of the English writer was especially embodied in mythological premises associated with the sphere of deepest questions of ethics and religious metaphysics.

Better Than Rational: A Naturalistic View of Economic Governance
Authors: Stoelhorst J.W.
Published: March 2021

The purpose of this paper is to present a recently emerging evolutionary approach to the study of human organization that I will refer to as ‘naturalistic’, and to highlight its integrative potential for the social and administrative sciences. This naturalistic approach considers the various forms of human cooperation as products of gene-culture co-evolutionary processes, and in doing so goes to the heart of the collective action problems that are central to explaining the human condition. Moreover, in building empirically grounded explanations of human behavior and organization, it also offers an alternative to the traditional view of governance in economic theory, with its emphasis on decentralized exchange and rational self-interested choice. The naturalistic approach both explains why human nature has evolved to the point where we often can do ‘better than rational’ in the face of the social dilemmas underlying collective action problems, and why modern forms of social, economic, and political organization are nevertheless always prone to being undermined by these same dilemmas.
Zum Wandel der Korrelation von Fertilität und Frauenerwerbstätigkeit in Raum und Zeit: Eine empirische Analyse unter Berücksichtigung der Effekte ausgewählter sozialer Indikatoren
Authors: Engelhardt Henriette
Published: March 2021

In OECD countries, the cross-country correlation between the total fertility rate and the female labour force participation rate turned from a negative value before the 1980s to a positive value thereafter. Based on pooled time-series analysis, the literature seems to agree that this change is due to unmeasured country and time heterogeneity with respect to female employment. However, the determinants of this heterogeneity remain unclear. Using data of 16 European countries from 1960-2005, I estimate pooled time-series models of fertility and female labor force participation by applying Prais-Winsten regressions with fixed country and time effects and investigate the changing effect of female labor participation for a set of labor market, educational and demographic variables and indicators of social policy. The empirical findings reveal that the change in the correlation seems to be due to the increasing proportion of females employed part-time, increasing educational attainment of females, increasing age at first birth and increasing gross enrollment ratio of children in pre-primary education.

Zusammenfassung

In den OECD-Ländern hat sich die Korrelation zwischen der Gesamtfertilitätsrate und der Frauenerwerbsquote über die Zeit von einem negativen Wert vor den 1980er Jahren zu einem positiven Wert gewendet. Dieser Wechsel ist offensichtlich durch unbeobachtete länderspezifische Heterogenität und durch Heterogenität in der Beziehung zwischen Fertilität und Erwerbstätigkeit über die Zeit bedingt. Die Determinanten dieser zeit- und länderspezifischen Heterogenität sind jedoch unklar. Basierend auf Daten aus 16 europäischen Ländern werden in der vorliegende Studie zusammengefasste Zeitreihenmodelle mit fixen Länder und Zeiteffekten geschätzt und die Veränderung des Effekts der Erwerbsbeteiligung von Frauen für Indikatoren des Arbeitsmarktes, der Bildungsbeteiligung von Frauen, proximale Determinanten der Fertilität sowie sozialpolitische Indikatoren untersucht. Die empirischen Ergebnisse legen nahe, dass der Wandel in der Korrelation durch die zunehmende Teilzeiterwerbstätigkeit und Bildungsbeteiligung der Frauen, dem Anstieg des Alters bei Geburt sowie dem steigenden Anteil Kinder in Vorschulerziehung bedingt ist.
Entscheidungsprozess zur Familiengründung in Partnerschaften
Authors: Pavetic Monika , Stein Petra
Published: March 2021

The transition to parenthood can be viewed as the result of social interaction. It signifies the outcome of a decision-making process of two individuals in a relationship. Nevertheless, little research has, so far, looked into how the interpersonal couple level influences the decision. What needs to be considered here is, firstly, the relative importance of both partners’ desire to have a child, or the partners’ disposition towards reproduction. Secondly, the reciprocal influence ,of both partners on each other within the decision-making process, and thirdly the relevance of both partners’ biographical background with regard to their respective decisions and disposition must be assessed. In this article, a nonlinear simultaneous probit model is introduced, with the help of which the relative effects of the decisionmaking process within the relationship can be estimated. The analysis is based on the “Bamberg Married Couples Panel”. The results of the model show an equal influence of both partners’ dispositions on the decision itself. However, they also demonstrate different levels of influence of the partners within the process of interaction and convergence.

Zusammenfassung

Obwohl der Übergang in die Elternschaft als Ergebnis einer sozialen Interaktion und damit als Ergebnis eines Entscheidungsprozesses zwischen zwei Individuen im Kontext einer Partnerschaft verstanden werden kann, existieren bisher kaum gesicherte Forschungserkenntnisse auf der Paarebene. Dieses betrifft erstens die relative Bedeutsamkeit der Kinderwünschebzw. Dispositionen beider Partner für die generative Entscheidung, zweitens die wechselseitige Beeinflussung beider Partner im Entscheidungsprozess und drittens die Relevanz der biographischen Kontexte beider Partner für die eigene Disposition sowie für die des Partners. Im Folgenden wird ein nicht-lineares simultanes Probit-Modell vorgestellt, mit dem die relativen Effekte im innerpartnerschaftlichen Entscheidungsprozess zur Familiengründung geschätzt werden können. Als Datengrundlage dient das Bamberger Ehepaar-Panel. Die Ergebnisse des Modells zeigen einen gleichwertigen Einfluss der Dispositionen beider Partner auf die Entscheidung, jedoch ungleiche Gewichte der Partner im Interaktions- bzw.Annäherungsprozess.
Child poverty in the German social investment state
Authors: Olk Thomas , Hübenthal Maksim
Published: March 2021

In the last years child poverty in Germany has become a political issue. However, child poverty rates are relatively high and even on the rise. Against this backdrop we will analyse the strategy of the federal government to fight child poverty in Germany. We will demonstrate that the federal government uses a ‘child-centred social investment strategy’ (cf. Esping-Andersen 2002) as a blueprint. By analysing measures and instruments of the German anti-poverty Strategy, we will make clear that this strategy is not completely put into effect. Whereas Esping-Andersen propagates a fine balance of social services and financial transfers, the German government underestimates the relevance of material redistribution and focuses predominantly on social services and education. This is not by chance but can be understood as a consequence of the conceptual limits of the social investment ideology. To guarantee generational justice and to make sure that children will receive a fair share of societal resources in a rich country we plea for a children’s rights-based approach to fight child poverty.

Zusammenfassung

Kinderarmut wurde in Deutschland in den letzten Jahren verstärkt zum Gegenstand der politischen Debatte. Dennoch sind die Armutsraten bei Kindern hoch und steigen sogar weiter an. Vor diesem Hintergrund analysieren wir in dem vorliegenden Beitrag die Strategie der Bundesregierung zur Bekämpfung der Kinderarmut in Deutschland. Dabei zeigen wir auf, dass die Bundesregierung ihr diesbezügliches politisches Handeln auf eine „kindzentrierte Investitionsstrategie“ (Esping-Andersen 2002) aufbaut. Anhand der Analyse der Maßnahmen und Instrumente zur Kinderarmutsbekämpfung arbeiten wir heraus, dass diese Strategievorlage allerdings nicht vollständig umgesetzt wird. Während Esping-Andersen eine ausgewogene Balance zwischen sozialen Dienstleistungen und finanziellen Transfers propagiert, unterschätzt die Bundesregierung die Bedeutsamkeit materieller Umverteilung und fokussiert ihr Handeln einseitig auf soziale Dienstleistungen und Bildung. Dies geschieht keinesfalls zufällig, sondern kann als Folge der konzeptuellen Schwächen der Sozialinvestitionsideologie verstanden werden. Um Generationengerechtigkeit zu gewährleisten und um sicherzustellen, dass Kinder einen gerechten Anteil an den gesellschaftlichen Ressourcen in einem reichen Land erhalten, plädieren wir zur Bekämpfung der Kinderarmut für einen Ansatz, der auf den Rechten der Kinder basiert.
Generationenbeziehungen im alternden Europa: Analysepotenziale und Befunde des Survey of Health, Ageing and Retirement in Europe
Authors: Hank Karsten
Published: March 2021

Building on exemplary analyses using micro-data from the Survey of Health, Ageing and Retirement in Europe (SHARE), this paper aims to provide an account of intergenerational relations in contemporary – ageing – Europe and to demonstrate the research potential of SHARE, which is now available as a longitudinal dataset. The findings presented here suggest, firstly, high levels of family solidarity across Europe and reflect, secondly, the manifold opportunities which SHARE provides for interdisciplinary and crossnationally comparative research investigating the dynamics of intergenerational relations.

Zusammenfassung

Anhand exemplarischer Analysen auf Basis von Mikrodaten des Survey of Health, Ageing and Retirement in Europe (SHARE) will der vorliegende Beitrag eine Bestandsaufnahme der Generationenbeziehungen im heutigen – alternden – Europa versuchen und gleichzeitig das Forschungspotenzial des inzwischen als Längsschnittdatensatz verfügbaren SHARE demonstrieren. Die hier präsentierten Befunde zeigen, erstens, dass überall auf dem Kontinent lebendige Beziehungen zwischen den Generationen bestehen und reflektieren, zweitens, die vielfältigen Möglichkeiten des SHARE für die interdisziplinäre und international vergleichende Erforschung der Dynamik von Generationenbeziehungen.
Die Rolle des Sexuallebens in einer romantischen Partnerschaft für die Beziehungszufriedenheit. Der Fragebogen zum Erleben von Sexualität in engen Partnerschaften (FESP)
Authors: Von Irmer Jörn
Published: March 2021

Research on romantic relationships has rarely investigated the role of sex. Therefore a questionnaire measuring the sexual experience along the two dimensions of physical and affective attraction has been developed. The results describe the fit between sexual experience and expectations as experienced by the participants. In a study with 1,583 participants, the questionnaire was proven reliable. Male participants reported suffering from not receiving enough attention within the physical domain. In a cross-sectional analysis, physical attraction was accorded a diminishing importance with increasing age of the participants. Affective attraction had an impact on relationship satisfaction. Affective attraction is an aspect of sex life which may be typical for sex in close relationships only. The effect of both dimensions of experiencing sex in close relationships on relationship satisfaction will be discussed with respect to age and gender effects.

Zusammenfassung

Die Rolle der Sexualität für romantische Partnerschaften ist ein wenig untersuchtes Gebiet in der Partnerschaftsforschung. Es wird ein Fragebogen vorgestellt, der das Erleben von Sexualität in engen Partnerschaften auf den zwei Dimensionen physische und affektive Anziehung erfasst. Er ermöglicht eine Beschreibung, was Partner in ihrer Sexualität erleben und wie dies mit ihren Wünschen in Einklang steht. In einer Studie an 1.583 Personen erweist sich der Fragebogen als reliables Messinstrument. Männer berichten größere Defizite in der physischen Anziehung. Außerdem wird sie im Querschnittsvergleich mit steigendem Alter immer negativer bewertet. Die affektive Anziehung ist ein Aspekt der Sexualität, der speziell für die partnerschaftliche Sexualität als zentral angesehen wird. Die Bedeutung dieser beiden Dimensionen des Erlebens partnerschaftlicher Sexualität für die Beziehungszufriedenheit unter Berücksichtigung von Alters- und Geschlechtseffekten wird diskutiert.
