Optimization of the Androgenesis Method in the In Vitro Culture of Anteneson the Basis ofT. AestivumHybrids

This study aimed to examine the regularities of the regenerationprocesses of haploid plants, the dependence of in vitro microspore morphogenesis in anther culture on optimization factors, and their efficiency in F1 hybrids of T. aestivumof different ecological and geographicorigin. It was found that heterosis contributed to an increased yield of haploid chlorophyll-bearing regenerants from hybrids obtained from the crossing of parental forms with different responsiveness to androclinia. Results were obtained for the complex optimization of the androgenesis method for the in vitro anther culture of T. aestivum, in order to create diploidized haploid lines (DHL) regardless of the influence of the genotype. The agroecological properties for a complex of economically useful traits were also assessed. DHLs were created that combined high yield (5.1-6.8 t / ha) with lodging resistance (straw height – 60-80 cm) and consistently high grain quality; these were characterized by increased resistance to major leaf diseases in comparison with the standard variety in the conditions of the Central Economic Region of the Non-Black Earth Zone of the Russian Federation. Keywords: spring soft wheat, androgenesis, embyroidogenesis, callusogenesis, diploidized haploids, in vitro, yield and quality

Of herds and societies—Seasonal aspects of Vinča culture herding and land use practices revealed using sequential stable isotope analysis of animal teeth

Late Neolithic Vinča communities, spread over much of central and northern Balkans during the late sixth to mid-fifth millennium BC and characterised by unusually large and densely population centres, would have required highly organised food production systems. Zooarchaeological analysis indicates that domesticate livestock were herded, but little is known about the seasonal husbandry practices that helped ensure a steady supply of animal products to Vinča farming communities. Here, we present new stable carbon (δ13C) and oxygen (δ18O) isotopic measurements of incremental bioapatite samples from the teeth of domesticated livestock and wild herbivore teeth from two late Neolithic Vinča culture sites: Vinča-Belo brdo and Stubline (Serbia). Our results show a low variation overall within sheep and goats in terms of pasture type that may have been composed of seasonal halophyte plant communities, which have higher δ13C values due to the saline rich growing environments. Cattle feeding strategies were more variable and provided with supplementary forage, such as cut branches or leafy hay, during winter. The sharp distinction in the management of cattle and sheep/goat may be associated with the development of herding strategies that sought to balance livestock feeding behaviours with available forage or, more provocatively, the emergence of household-based control over cattle–an animal that held a central economic and symbolic role in Vinča societies.

ANALYZING THE PLATFORM ECONOMY – FEUDALISM, MEDIEVALISM AND COLONIALISM AS USEFUL FRAMEWORKS

The platform economy challenges existing economic systems, social interactions and participation as well as the very foundation of democracy. As data is replacing labor as the central economic good, economy, society, class structures and democracy might change fundamentally. Or we might experience old wine on new bottles. Karl Marx famously said that history tends to repeat itself, first as comedy, later as tragedy. In this panel we ask, whether history is repeating itself? The panel’s speakers employ different historical perspectives but focus mainly in two periods: medieval times and the age of colonialism. Both periods were characterized by a strong correlation between a certain economic system and the exercise of political power. Structured inequalities in systems of labor, trade and distribution of wealth had significant consequences for the distribution and (re)production of political power. Medieval and colonial societies were each based on logics of exploitation and dominance, ideologically legitimized by references to first God, later the nation, what Marx would have referred to as the superstructures of economic logics. In this systems, individual agency and possibilities were limited compared to today. In medieval society it was hard to change the estate in which you were born, in colonial times it was hard to change your role in the international system. And the fixed structures were basically grounded in economic logics.

Are Resource-Rich Regions Impacted More by Covid-19 Pandemic? Comparing Economic and Mobility Impact in Indonesia’s Provinces

The coronavirus pandemic has caused negative impact on economy as it limits people interactions from their normal life. This paper tries to compare the effects on economic growth and visits by locals to central economic places (retail and recreation, grocery and pharmacy stores, parks, and workplaces) of Covid-19 in Indonesia’s provinces as social restrictions applied. By using Google’s mobility report data combined with the second quarterly GRDP data across Indonesia’s sub-national level, we compare economic and mobility performances between “the treated provinces” located in Sumatra, Kalimantan and Papua Islands (SKP) who’s their economy has been dominated by natural resources-based sectors (e.g., palm oil, natural gas, oil and coal) and “the untreated provinces” in Java-Bali-and Eastern Regions (Sulawesi, Maluku, Nusa Tenggara), henceforth JBE. We visualize and provide scatterplots to depict relationships between selected variables. We also test whether each impact differs between SKP and JBE. Our study finds that while almost all provinces have been impacted negatively during the pandemic, its effects graphically differ among regions, while Java’s provinces have looked to be affected strongly. However, our statistical analyses based on Welch’s and Levene’s tests provide weak evidence that the pandemic harms regions disproportionately.

Towards climate resilient peace: an intersectional and degrowth approach

How can peace be climate resilient? How can peace and environmental sustainability be advanced simultaneously? To address these questions, I develop a new conceptual and theoretical framework for climate resilient peace through degrowth. This paper calls for stronger consideration of positive conceptualizations of peace and of intersectionality and degrowth in pursuit of peace and resilience. Not only does climate change make planetary limitations more salient, but it also highlights rising inequalities. In light of this, peace necessitates transforming societal power structures that are both driving climate change and influencing people’s experiences of climate impacts. Addressing imbalanced power structures then is key to understanding and fostering climate resilient peace. This paper conceptualizes climate resilient peace based on an intersectional understanding of positive peace, highlighting that peace depends on the negation of structural violence experienced at the intersection of political and social identities. In relation to this, I argue that a process of climate resilient peace must address underlying power structures influencing people’s experience of climate harms, and driving climate change so as to mitigate further damage. This paper demonstrates such a process through degrowth, wherein growth is no longer the central economic goal, exemplifying social and ecological means for disrupting structural violence within climate limitations. I discuss and give examples of three key degrowth processes—redistribution, reprioritized care economies, and global equity—as opportunities to foster peace in a changing climate. This framework, thus, contributes a new approach to climate resilient peace that addresses challenges of both social and environmental sustainability.
