Precarization, Genderization and Neotaylorist Work: How Global Value Chain Restructuring Affects Banking Sector Workers in Brazil

The transnationalization of financial markets impacted on the fragmentation and recomposition of value chains which induced comprehensive processes of outsourcing and the commodification of bank services. This paper explores how this translates into the sectoral and internal reorganization of Brazilian banks and how work organization and social relations are affected. The case of (bank-owned as well as outsourced) call center not only reflects changes in the importance and form of service relations but also shapes a neotayorist reorganization of the labor process and the respective modes of control. As a result, a complex process of precarization and segmentation of the work force can be observed which impacts on new lines of inequality related to categories like gender, class and race. The analysis is based on a theoretical approach which refers to Michael Burawoy’s concept of the “politics of production” and categories of Pierre Bourdieu’s social theory like symbolic violence. This allows an analysis of power relations which also includes the dimension of identities. Thus a more fine-grained insight can be gained on how transnational restructuring affects redistribution on a macro, meso and micro level

Potential and limitations of Burgundy truffle cultivation

Burgundy truffles (Tuber aestivum syn. Tuber uncinatum) are the highly prized fruit bodies of subterranean fungi always occurring in ectomycorrhizal symbiosis with host plants. Successful cultivation can be achieved through artificial mycorrhization and outplanting of mostly oaks and hazel on suitable terrain. Here, we review ecological requirements, the influence of environmental factors, and the importance of molecular techniques for a successful cultivation of T. aestivum across Europe. The historical background and current knowledge of T. aestivum cultivation are discussed in light of its socioeconomic relevance

Introduction

Plomien A, Scheele A, Sproll M. Global Contestations of Social Reproduction. Compounding Crises and COVID-19. In: Scheele A, Roth J, Winkel H, eds. Global Contestations of Gender Rights. Bielefeld: Bielefeld University Press / transcript Verlag; 2022: 163-182.Across the globe, a growing number of social movements, such as demonstrations in support of equal civil status or reproductive freedom and against sexualized violence, show that women's and gender rights are highly contested. Against the backdrop of a long history of unequal rights implementation, the contributors to this volume deal with the questions of why and in which ways gender equality has become contested in various political contexts. Local case studies examine the relevant structural, institutional, and socio-cultural causes of the global challenges to equality. This book follows an interdisciplinary approach and unites scholars from law, linguistics, cultural studies, history, social sciences, and gender studies in diverse contexts

New evidence for the symbiosis between Tuber aestivum and Picea abies

The Burgundy truffle (Tuber aestivum Vittad.), an ectomycorrhizal fungus living in association with host plants, is one of the most exclusive delicacies. The symbiosis with deciduous oak, beech, and hazel dominates our concept of truffle ecophysiology, whereas potential conifer hosts have rarely been reported. Here, we present morphological and molecular evidence of a wildlife T. aestivum symbiosis with Norway spruce (Picea abies Karst.) and an independent greenhouse inoculation experiment, to confirm our field observation in southwest Germany. A total of 27 out of 50 P. abies seedlings developed T. aestivum ectomycorrhizae with a mean mycorrhization rate of 19.6 %. These findings not only suggest P. abies to be a productive host species under suitable biogeographic conditions but also emphasize the broad ecological amplitude and great symbiotic range of T. aestivum. While challenging common knowledge, this study demonstrates a significant expansion of the species' cultivation potential to the central European regions, where P. abies forests occur on calcareous soils

The fall of the summer truffle : Recurring hot, dry summers result in declining fruitbody production of Tuber aestivum in Central Europe

Global warming is pushing populations outside their range of physiological tolerance. According to the environmental envelope framework, the most vulnerable populations occur near the climatic edge of their species' distributions. In contrast, populations from the climatic center of the species range should be relatively buffered against climate warming. We tested this latter prediction using a combination of linear mixed effects and machine learning algorithms on an extensive, citizen-scientist generated dataset on the fruitbody productivity of the Burgundy (aka summer) truffle (Tuber aestivum Vittad.), a keystone, ectomycorrhizal tree-symbiont occurring on a wide range of temperate climates. T. aestivum's fruitbody productivity was monitored at 3-week resolution over up to 8 continuous years at 20 sites distributed in the climatic center of its European distribution in southwest Germany and Switzerland. We found that T. aestivum fruitbody production is more sensitive to summer drought than would be expected from the breadth of its species' climatic niche. The monitored populations occurring nearly 5°C colder than the edge of their species' climatic distribution. However, interannual fruitbody productivity (truffle mass year-1 ) fell by a median loss of 22% for every 1°C increase in summer temperature over a site's 30-year mean. Among the most productive monitored populations, the temperature sensitivity was even higher, with single summer temperature anomalies of 3°C sufficient to stop fruitbody production altogether. Interannual truffle productivity was also related to the phenology of host trees, with ~22 g less truffle mass for each 1-day reduction in the length of the tree growing season. Increasing summer drought extremes are therefore likely to reduce fruiting among summer truffle populations throughout Central Europe. Our results suggest that European T. aestivum may be a mosaic of vulnerable populations, sensitive to climate-driven declines at lower thresholds than implied by its species distribution model.publishe

Fine-scale genetic structure of natural Tuber aestivum sites in southern Germany

Although the Burgundy truffle (Tuber aestivum) is an ectomycorrhizal fungus of important economic value, its subterranean life cycle and population biology are still poorly understood.Here, we determine mating type and simple sequence repeat (SSR) maternal genotypes of mapped fruiting bodies to assess their genetic structure within two naturally colonized forest sites in southern Germany. Forty-one genotypes were identified from 112 fruiting bodies. According to their mating types, the maternal genotypes were aggregated only in one population. Genotypic diversity of individuals that mostly were small and occurred in 1 out of 2 years of sampling was high. Although these results suggested a ruderal colonization strategy, some genets spread several hundred meters.This result indicates that, besides sexual spore dispersal, vegetative growth or spreading by mycelial propagules contributes to dissemination. In one site, fewer individuals with a tendency to expand genets belonging to only one genetic group were observed. In the second site, numerous small individuals were found and were grouped into two clearly differentiated genetic groups that were spatially intermingled. Forest characteristics and disturbances are possible reasons for the observed genetic patterns.Our findings contribute to a better understanding of the biology of one of the most widespread and commercially important truffle species. This knowledge is critical for establishing and maintaining sustainable long-term truffle cultivations
