Gender Roles of Indigenous Women Reindeer Herders in Transition with Particular Reference to the Arctic Siberian Tundra Areas: Challenges of Social (In)Security

The changing role of women in the traditional Indigenous communities of the Russian Arctic in the 21st century is a rarely studied phenomenon. However, this is an important period of significant strengthening of their civil, political and social rights compared to the 18th to 19th centuries, when gender inequalities and strict subordination of women limited their choices. Now, their voices can be heard: they can participate in political life and lobby for their rights to regional and federal authorities. However, some social insecurities still remain for women reindeer herders. During the last decade, gender asymmetries concerning lifestyle, educational level and marital behaviour have intensified and resulted in increasing emigration of women from the tundra as they have chosen to abandon their traditional lifestyles and move to urban areas. This chapter analyses the changing position of women in traditional reindeer herding societies and whether these transformations have improved women’s social security, reduced gender inequality and increased social justice. To increase the social security of women reindeer herders, the authors recommend encouraging these women to apply for official self-employment (samozanjatyj) status (special tax regime with a tax on professional income), supporting cooperative forms of reindeer herding husbandry that employ women reindeer herders, encouraging the semi-nomadic lifestyles of Indigenous women, developing facilities in settlements for processing reindeer herding products that are managed by reindeer herders’ families, organising production cooperatives for reindeer herders to develop facilities for deep processing of reindeer products and increasing the profitability of reindeer herding

Properties of LiGa0.5In0.5Se2: A Quaternary Chalcogenide Crystal for Nonlinear Optical Applications in the Mid-IR

LiGaSe2 (LGSe) and LiInSe2 (LISe) are wide band-gap nonlinear crystals transparent in the mid-IR spectral range. LiGa0.5In0.5Se2 (LGISe) is a new mixed crystal, a solid solution in the system LGSe–LISe, which exhibits the same orthorhombic structure (mm2) as the parent compounds in the same time being more technological with regard to the growth process. In comparison with LGSe and LISe its homogeneity range is broader in the phase diagram. About 10% of the Li ions in LGISe occupy octahedral positions (octapores) with coordination number of 3. The band-gap of LGISe is estimated to be 2.94 eV at room temperature and 3.04 eV at 80 K. The transparency at the 0-level extends from 0.47 to 13 µm. LGISe crystals exhibit luminescence in broad bands centered near 1.7 and 1.25 eV which is excited most effectively by band-to-band transition. From the measured principal refractive indices and the fitted Sellmeier equations second-harmonic generation from 1.75 to 11.8 μm (fundamental wavelength) is predicted. The nonlinear coefficients of LGISe have values between those of LGSe and LISe. 6LGISe crystals are considered promising also for detection of thermal neutrons

Traditional nutrition of Indigenous Peoples in the Arctic zone of Western Siberia : challenges and impact on food security and health

The chapter presents traditional nutrition as a part of the traditional culture of the nomadic Indigenous population in the Arctic zone of Western Siberia. Traditional nutrition effectively prevents health problems and enables people to adapt to the harsh climate conditions of the High North. This chapter analyses the implementation of Russian national policies on traditional reindeer herding in this region that is affected by issues of food security and food sovereignty. Export trends of traditional products have decreased local Indigenous Peoples’ access to venison, negatively impacting their health

Food Sovereignty of the Indigenous Peoples in the Arctic Zone of Western Siberia: Response to COVID-19 Pandemic

This article presents the challenges facing reindeer herding as being both a profitable business and part of the traditional culture of the nomadic Indigenous peoples in the Arctic zone of Western Siberia which addresses substantial needs of the local population. Reindeer herding products are used as traditional nutrition, and as effective preventive means and remedies for adapting to the cold and geomagnetic activity in the High North. Export trends of traditional reindeer products have decreased local Indigenous peoples' access to venison and had a negative impact on their health. Due to the COVID-19 pandemic, it is especially urgent for the Indigenous peoples to have sufficient access to traditional food and be involved in policy decision-making to maintain this traditional business. We aim to analyze the dependencies of Indigenous peoples on the reindeer produce-exporting "food value chain" and explore how (1) the independence of reindeer herders could be increased in these export chains and (2) how provision of their products to local communities could be secured. The study takes a multidisciplinary approach based on policy and socioeconomic analyses with input from medical research. Primary sources include data collected from interviews and surveys of Indigenous peoples during expeditions to the Nyda settlement, the Nydinskaya tundra, the Tazovsky settlement, the Tazovskaya tundra, the Nakhodka tundra, the Gyda and Gydansky settlements, the Yavai-Salinskaya tundra, the Seyakha settlement, the Seyakhinskaya and Tambeyskaya tundras located along the southern coast of the Ob Bay, the northeast coast of the Yamal Peninsula, the Tazovsky and Gydansky Peninsulas, and the Shuryshkarsky district. Data were collected during the summers and winters of 2014-2020

The Impact of Environmental and Anthropogenic Factors on the Migration of the Rural Arctic Population of Western Siberia

Environmental and anthropogenic factors represent challenges impacting the lifestyle and demographic rural population’s behaviour in the Russian Arctic that threaten its social and food security. We aim to explore (1) which key “push” factors are jeopardising social sustainability and increasing migration outflows in the Arctic rural communities of Western Siberia (2) and how the Siberian population’s sustainable development could be secured. The methodology and analysis were based on Lee’s theory of migration factors with the main focus on the “push” factors forcing people to migrate to other Arctic and non-Arctic territories. The primary sources included fieldwork data and interviews collected during expeditions to the Arctic zone of Western Siberia between 2000 and 2021. Both men and women confirmed the insignificant impact of environmental factors on their emigration plans. However, they signified social and personal motives related to low standards of living that threatened their social and food security. The rural Siberian population’s migration strategies could be re-evaluated only by increasing the physical availability of food products and developing the social infrastructure of the settlements as either “models of rural cities” or “service centres for nomadic and rural population”

Sino-Russian cooperation on the sustainable utilization of Arctic biological resources: modernizing traditional knowledge

Considering the effects of global warming, humans need to face the possibility of an ice-free Arctic during summer. Russia spans Eurasia and occupies more Arctic lands than any other country. This vast area has a great variety of species, and the geography and environment of the Arctic have endowed these species with unique and valuable properties. All the world’s ancient nations have their traditional knowledge. The indigenous traditional knowledge of the Arctic and the knowledge embedded in traditional Chinese medicine are part of the world’s time-honored wisdom. Some of this ancient lore cannot be verified by modern scientific methods, but the methods are effective in practice, triggering further exploration and innovation. Russian Arctic indigenous people have a long history of using the Arctic biological resources. The use of therapeutic materials in traditional Chinese medicine has many similarities with the use of Arctic biological resources by indigenous peoples. Both types of traditional knowledge can inspire new approaches to the development of the Arctic biological resources. China and Russia are among the world’s largest countries, and it is important that they cooperate in developing the Arctic biological resources. The development of sustainable use of these resources, while updating traditional knowledge, is an urgently needed investment that requires an innovative approach

Long-term outcomes of different rehabilitation programs in patients with long COVID syndrome: a cohort prospective study

After the resolution of the acute SARS-COV-2 infection, an important percentage of patients do not fully recover and continue to present several symptoms. Nevertheless, there is a lack of data in the literature on the effects of rehabilitation programs on medium- and long-term long COVID symptoms. Therefore, the aim of this study was to evaluate the long-term outcomes after rehabilitation programs in long COVID syndrome patients. A prospective cohort study was conducted from August 2021 to March 2022, involving 113 patients with long COVID syndrome. The patients in the experimental group (EG, n=25) received a tailored and multidisciplinary rehabilitative program, involving aquatic exercises, respiratory and motor exercises, social integration training and neuropsychologic sessions, LASER therapy and magnetotherapy. Patients in the other three comparison groups received eastern medicine techniques (CG1), balneotherapy and physiotherapy (group CG2), self-training and home-based physical exercise (CG3). Once the several rehabilitation protocols had been performed, a structured telephone contact was made with the patients after 6 months ± 7 days from the end of the rehabilitation treatment, in order to record the frequency of hospital ad-missions due to exacerbation of post-exacerbation syndrome, death or disability, and the need for other types of care or drugs. The patients in the comparison groups were more likely to request therapeutic care for emerging long COVID symptoms (χ2=6.635, p=0.001; χ2=13.463, p=0.001; χ2=10.949, p=0.001, respectively), as well as more likely to be hospitalized (χ2=5.357, p=0.021; χ2=0.125, p=0.724; χ2=0.856, p=0.355, respectively) when compared to the patients of the EG. The relative risk (RR) of hospital admissions in the observed cohort was 0.143 ±1,031 (СI: 0.019; 1.078); 0.580±1,194 (CI: 0.056; 6.022); 0,340±1,087 (CI: 0.040; 2.860). The RR of hospital admissions for patients with long COVID syndrome was reduced by 85.7%; 42.0% and 66.0%, respectively, when the experimental rehabilitation technique was employed. In conclusion, a tailored and multidisciplinary rehabilitative program seems to have a better preventive effect not only in the short term, but also over the next 6 months, avoiding the new onset of disabilities and the use of medicines and specialist advice, than other rehabilitative programs. Future studies will need to further investigate these aspects to identify the best rehabilitation therapy, also in terms of cost-effectiveness, for these patients

Optical, vibrational, thermal, electrical, damage and phase-matching properties of lithium thioindate

Lithium thioindate (LiInS$_{2}$) is a new nonlinear chalcogenide biaxial material transparent from 0.4 to 12 $\mu$m, that has been successfully grown in large sizes and good optical quality. We report on new physical properties that are relevant for laser and nonlinear optics applications. With respect to AgGaS(e)$_2$ ternary chalcopyrite materials, LiInS$_{2}$ displays a nearly-isotropic thermal expansion behavior, a 5-times larger thermal conductivity associated with high optical damage thresholds, and an extremely low intensity-dependent absorption allowing direct high-power downconversion from the near-IR to the deep mid-IR. Continuous-wave difference-frequency generation (5-11$\mu$m) of Ti:sapphire laser sources is reported for the first time.Comment: 27 pages, 21 figures.
