Detaching from the Nine-to-Five: How Retirement and Genetics are related to Chronotype
Authors: Landvreugd Anne , Nivard Michel Guillaume , Bartels Meike
Published: December 2024

Introduction: Our sleep-wake rhythm is determined by the interaction of our work-life balance, i.e. the ‘social clock’, and our biological clock. After retirement, the social restrictions generally loosen up, possibly giving more room for our genetic predispositions to regulate the sleep-wake rhythm. In this study, we investigated shifts in wake-up times and chronotypes during employment and retirement. We hypothesized that the variance of chronotype explained by genetics is larger in retirees compared to employees. Method: We used data from 20.189 participants from the Netherlands Twin Register. First, we fitted a regression model to assess the association between chronotype and age. Second, we applied a mixed-effects model to test whether the type of day (working day or non-working day) is a predictor of wake-up time in early birds and late risers. Third, we separated the employed from the retirees and performed a regression to assess the prevalence of chronotypes in the two groups. Fourth, we tested whether the two groups differed in their wake-up times on working days and non-working days using quantile regression. Finally, we used polygenic scores for Morningness to predict the variance in Chronotype in the employed and retirees. Results: Chronotype was both linearly and quadratically related to age. Both early and late risers have later wake-up times on non-working days compared to working days. Employment status was not a predictor of chronotype, but rather of wake-up time on working days. The effect of the polygenic score for Morningness on Chronotype did not depend on employment status. Discussion: Our study showed that the social clock influences wake-up time on working days, but not chronotype, making chronotype a relatively stable trait. Additionally, the social clock does not suppress the genetic predisposition for chronotype. These analyses enhance our understanding of how both society and genetics influence our chronotype and sleep-wake rhythm.

A prospective partner’s sexual history provides important information that can be used to minimise mating-related risks. Such information includes the number of past sexual partners, which has an inverse relationship with positive suitor evaluation. However, sexual encounters with new partners vary in frequency over time, providing an additional dimension of context not previously considered. Across three studies (N = 5,331) with 15 samples, we demonstrate that the impact of past partner number on a suitor’s desirability varies as a function of distribution over time. Using graphical representations of a suitor’s sexual history, we found that past partner number effects were smaller when the frequency of new sexual encounters decreased over time. This moderation effect was stronger, and often curvilinear, when past partner numbers were higher. We replicated these findings in 11 countries from five world regions. Sex differences were minimal and inconsistent pointing to a lack of a sexual double standards. Sociosexuality (openness to casual sex) was a consistent moderator and tended to mute the sexual history effects. These findings suggest that people not only attend to a potential mate’s quantity of sexual partners, but also the context surrounding these encounters such as pattern and timing. Together, the findings raise the possibility of an evolved mechanism for managing mating risks present in both sexes and across populations and adds nuance to a contentious topic of public interest.

Published: December 2024

The working class, referred to as the proletariat in Marxist terminology, comprises all individuals who receive compensation through wage or salary-based employment contracts. This study examined the economic impact of COVID-19 in Kathmandu district among different professions of working class, or proletariat. Using a pragmatic approach with both deductive and inductive methods, the study focused on three purposively selected municipalities in Kathmandu: Kirtipur, Kathmandu Metropolitan City, and Gokarneshwor. Respondents included private school teachers, daily wage workers, small business owners, farmers, and transportation laborers. A cluster-stratified sampling design was used, with a sample of 324 determined by Cochran’s formula. The study employed a descriptive research design, collecting both quantitative and qualitative data through interviews, focus group discussions (FGD), and key informant interviews (KII). The mean monthly income dropped from Rs.18,176.85 before the pandemic to Rs.9,518.52 during the pandemic. The lower coefficient of variation after the pandemic (31.1%) indicated a significant income effect. Financial problems were reported by 77.8% of private school teachers and a significant portion of other professions. The chi-square test (χ² = 104.864, p = 0.000) highlighted significant livelihood problems across professions. Recommendations included cash distribution (48.1%), food support in scarce areas (28.7%), and improved access to medicine (21.3%). The study draws on Keynesian theory, noting government interventions to restore employment but reveals dissatisfaction with these efforts among local victims of the pandemic. It suggests further policy development to support agricultural productivity, create emergency funds for the working class, and explore post-COVID recovery strategies.

IMPACT OF THE WAR ON THE SPHERE OF EDUCATION IN UKRAINE AND THE SOCIAL AND PSYCHOLOGICAL SITUATION OF STUDENTS
Authors: Tilikina Nataliia
Published: December 2024

In the article there has been studied the impact of the full-scale Russian invasion on February 22, 2022 on the Ukrainian system of education and the structural changes in the student youth population. The war has caused not only physical destruction and damage of a significant quantity of educational institutions, but has also forced a significant part of population, the youth in particular, to move to safer regions or abroad. According to the data from the International Organization for Migration, the number of refugees from Ukraine has reached almost 6 million people, more than 2 million from which are children. The issue of the gender imbalance has also become specifically topical since the majority of people, who left, are women. Furthermore, students’ flows have also been affected by these changes. Adoption of new rules for going out abroad of male students has caused the decrease of a number of people, who could go abroad for studying, and that, in its turn, has also been reflected in the general structure of students. The number of Ukrainian students, who were studying abroad, continued to increase. At the same time the trend in Ukraine has been stable, although the number of students continued to decrease in the institutions of vocational and higher education due to demographic and migration processes. A significant factor influencing educational processes has also been socio-economic and psychological challenges, which students have faced during the war. Loss of the opportunity to study due to financial difficulties, migration or danger has become a widespread issue among the youth. Moreover, military actions have negatively impacted emotional state of students. The studies indicate that a large number of youth felt fear, anxiety and other negative emotions at the beginning of the war, and 1 year after the invasion these emotions underwent changes – the fear and anxiety reduced, but hatred, aggression and other negative feelings boosted.In general, the situation with the educational process in the war context in Ukraine is difficult, and includes demographic, social and psychological aspects. The student youth, as one of the most vulnerable population categories, keeps adapting to new circumstances, facing numerous challenges, the most important of which are safety, stability and access to quality education.
Feathered Foes
Authors: Tilburg Patricia
Published: December 2024

When turn-of-the-century conservationists in the United States and Europe began to lambast and promote legislative action against the use of exotic bird feathers in women's fashion, French naturalists stood apart from their Anglo-American colleagues in offering an ecological program that emphasized the needs of the French feather trade. This article explores the particular French cultural investment in fashion not only by feather tradesmen but also by conservationists from the 1890s through the 1920s. This attachment to the importance of women's luxury fashion as a French national patrimony meant that French response to proposed feather bans by the United States and Great Britain included a more sympathetic address to the bourgeois woman consumer and patriotic praise for the skill and taste of the workingwomen of the Parisian feather trade.

Published: December 2024

This study aimed to study the social exclusion of transgender in Hazara Division of Khyber Pakhtunkhwa province of Pakistan. The study used qualitative research method in which data was collected through in-depth interviews with 25 respondents in the selected locales. The collected data was thematically analyzed and the results suggest that transgender face social exclusion which further exacerbates the vicious circle of discrimination, harassment, and violence from the broader society. It is concluded from the study that due to complex and debatable nature of the issue and the discriminative behavior of society toward transgender leads towards their sexual victimization, stigma, sexual abuse and violence. It is recommended that that the existing laws and policies regarding physical and sexual violence against transgender may be reassessed and to take concrete policy measures to ensure the mainstreaming of transgender in society.
Migrations in the late Neolithic – Eneolithic in the Volga-Ural region: archaeology, chronology, paleoclimate
Authors: Vybornov Alexander A. , Gilyazov Filat F. , Doga Natalya S. , Kulkova Marianna A.
Published: December 2024

The Volga-Ural region draws attention of experts because of the Khvalynian Eneolithic spreading across this territory. Archaeologists consider autochthonous, migration and combined hypotheses for this culture. The findings of anthropological and paleogenetic analyses support the combined hypotheses. The components that comprise the basis of the Khvalynian tribes are determined in this region. The investigations in the field of natural sciences establish two components including the northern and southern hunters. Archaeologists face the problem of cultural attribution of these subjects. Analysis of ceramics and stone tools allow us to consider the following. Due to the deterioration of climatic conditions, the carriers of the earlier stage of Nizhnedonskaya culture moved to the Northern Cis-Caspian region. There is no evidence of cattle breeding among carriers of this culture. They possessed such innovations as comb ornamentation of wares, bifacial processing of heads and replaceable blade tool-making technique. Interaction with the local Late Neolithic (Tenteksor) culture led to the Cis-Caspian culture emerging in the last quarter of the 6th millennium BC. The substrate base is characterised with motifs and compositions of pottery ornamentation that will become typical for the migrants. There is no evidence of a production economy in the Tenteksor culture. In the Cis-Caspian culture, some early features of cattle breeding are found. Therefore, the Cis-Caspian culture people can be attributed as southern hunters. Driven by aridization, they moved to the border of the steppe and forest-steppe of the Low Volga region. Contacts between these tribes and the local Neolithic Srednevolzhskaya culture led to the Samarskaya culture forming. The superstrate component gave this culture vessels with collars, bifacial heads and their shapes, and replaceable blade stone tool-making technique. These tribes can be considered northern hunters. It needs to be taken into consideration that the Srednevolzhskaya culture goes back to the earlier Elshanka culture, therefore, this component has a stable local tradition. Caucasian elements in the Neolithic and Eneolithic materials are not found. The new data allow us to claim the climatic factors to drive the migration processes rather than the type of economy. The climatic conditions drove cultural groups in the Khvalynian culture period as well.
Fortifications of the Ust-Tersyuk fortified settlement of the Early Middle Ages
Authors: Matveeva Natalia P. , Rafikova Tatiana N. , Tretyakov Evgenii A. , Yakimov Artem S.
Published: December 2024

The article analyses early medieval structures of the outer fortification line in Ust-Tersyuk hillfort by the Iset River. The research is based on excavation finds made in 2010 and 2023. The fortified cape settlement is surrounded by a protection structure all around. Besides, it has two transverse structures that separate the cape and gullies and form two sites. One of the sites is pentagonal, the other one is octagonal. It is established that the structure lasted through at least four periods of functioning. These periods are separated from one another by intervals of desolation several centuries each. During these idle intervals the burial soil profiles started to form. Two early episodes are associated with the Bakalskaya culture and dated 300–400s. At that time the highest point was isolated all around with a stake wall as a temporary defence until earth works are over. Later the stake wall was disassembled and replaced with a low rampart, a 2 m wide berm and a moat across the slopes. In 500–800s the Bakalskaya culture people enhanced the defence with a mound and a 1.1 m wide wall over the mound. The wall cavity was filled with soil brought from the settlement site. Differences in the design of the wall on the cape (fence) and in the west flank (log framework) can be interpreted as different time of construction or troubled material delivery. The moat was relocated down the slope. The berm was enhanced to reach 5.5 m. In 1000s–1200s (Yudino culture) the moat around the hillfort was renovated. But the research is yet to establish the type of woks conducted on the ramparts. Every new episode of construction stands out with increasingly more efforts and attack marks. During the Bakalskaya culture the soil was meadow chernozem. The climate was warmer and humid due to close creeks. Later the climate got cooler and formed grey wood soil.

Published: December 2024

The solid thin films of Py/Pt and Py/W heterostructures have been studied using the ferromagnetic resonance method. The temperature dependences of the Gilbert damping parameter and voltage of the the inverse spin Hall effect (ISHE) have been obtained in the 5–290 K temperature range. An anomalous increase in the Gilbert damping parameter in the vicinity of 50 K and a change in the voltage of ISHE has been found. It has been concluded that an increase in the Gilbert damping parameter is of spin-orbital nature.

Published: December 2024

X-ray diffraction analysis, ellipsometry and optical microscopy have been used to study aluminum alloys samples (Al and Al–2.3% V) fabricated by 3D printing using selective laser melting. The mechanical properties of the resulting products have been compared. The strength and plastic properties of parts made from pure Al and Al–2.3% V alloys have been found to be insensitive to heat treatment. The addition of vanadium to pure Al showed that the Al–2.3% V alloy has significantly improved performance properties compared to those of primary aluminum, without affecting its initial plasticity.
Haplotypic diversity of Leptidea morsei (Fenton, 1882) (Lepidoptera, Pieridae) on the northwestern periphery of the area
Authors: Kulakova O. I. , Shadrin D. M. , Tatarinov A. G.
Published: December 2024

The ﬁrst data on haplotypic diversity in natural populations of the L. morsei in the north-east of the Russian plain and in the northern regions of the Urals have been obtained. Our interest is caused by the fact that the northwestern border of this species distribution passes here. Six haplotypes were identiﬁed, of which ﬁve were found only in the studied region. A comparative analysis of haplotypic diversity in different parts of the species range and the geographical distribution of haplotypes allowed us to draw a preliminary conclusion that the population groupings of L. morsei in the north-west of the range have greater genetic similarity with Asian populations than with isolated Central European ones. The settlement of this species to the north of the Russian Plain and the Urals in the post-Glacial epoch obviously took place along the south of the West Siberian Plain through the Southern Trans-Urals.

Published: December 2024

Type 2 diabetes mellitus (T2DM) is a disease characterized by increased blood glucose, formed as a result of impaired mechanisms of insulin binding to cells. DNA samples of patients with T2DM (N = 535) and healthy individuals (N = 475) were used. We identified the association of lncRNA gene loci LINC02227 rs2149954 (OR = 0.76, P = 0.0083, PFDR = 0.017), LINC00305 rs2850711 (OR = 1.43, P = 0.0017, PFDR = 0.004) and CDKN2B-AS1 rs4977574 (OR = 0.70, P = 0.0001, PFDR = 0.0003) in an additive model with T2DM. The LINC00305 gene locus rs2850711 showed association with fasting glucose level (P = 0.023), C-peptide level (P = 0.00001), LINC02227 rs2149954 and CDKN2B-AS1 rs4977574 loci showed association with hypertension. MALAT rs619586 gene polymorphism was associated with C-peptide (P = 0.017), LDL (P = 0.012) and total cholesterol levels (P = 0.01). CDKN2B-AS1 rs4977574 gene polymorphism showed association with C-peptide levels (P = 0.027). SNP LINC02227 rs2149954 was associated with obesity (P = 0.0011, PFDR = 0.008). MEG3 rs7158663 gene polymorphism was associated with post infarct cardiosclerosis (P = 0.02). ROC curve analysis showed that the studied loci and variables such as sex, age of subjects and BMI level, included in the construction of the risk calculation model, could predict the development of T2DM with a sensitivity of 98.0% and specificity of 97.0%, the area under the AUC curve was 95.30% (95%CI 93.50–97.40).
“I Definitely Would Not Be Doing Science…”, or Features of the Status Transmission in Scientific Dynasties in Russia
Authors: Isaev Dmitry P. , Posukhova Oxana Yu.
Published: December 2024

The article discusses the problem of value orientations in scientific dynasties of Russia in the 20th century. An interdisciplinary historical, sociological and anthropological perspective focused on a socio-historical approach was applied to the study of intergenerational interaction. Evolved on the developed classification of transmission status models in professional dynasties, the authors sought to identify the features and patterns of the choice of certain types of succession by members of the dynasties during а specified period. The following observations were made with the help of sociological data. Hence, according to the study, the reform spirit of the 1950s – 1960s corresponds to the model of active succession. The transition to a conservative model of political and economic development of the country in the Brezhnev period, and the evolution of the image of a scientist as a mass researcher lead to the spread of a passive model of professional inheritance. However, the internal patterns of mastering professional practices in academic families should be also accounted. Moreover, in the context of socio-political and economic transformations in Russia in the 1990s, subsequent generations “X” and “Y” demonstrate a full set of models for the professional status transmission, such as transprofessional mobility, active and passive models. Under conditions of “depressurization” of the scientific community, hybrid transmission models, characterized by a partial return to basic scientific values, enriched by the actualization of subjective life experience, turned out to be possible.

Published: December 2024

The article examines the evolution of leadership models in a VUCA environment characterized by instability, uncertainty, complexity, and ambiguity. The impact of these factors on distribution companies is analyzed, including changes in consumer behavior, personnel, and business processes. The results of the study show that the shortening of product life cycles and the growth of customer expectations have significantly complicated management processes. For example, technological innovations have reduced the product update cycle to 6 months. We analyze examples of companies such as Amazon and Walmart, which use demand forecasting systems to reduce logistics costs by 15–20%. The article develops practical recommendations for improving management approaches and proposes a leadership model adapted to modern challenges, in particular through the introduction of personalization and innovation. This study provides relevant information for improving the efficiency of distribution management in the face of global changes.

The paper analyzes the structure of the market share of revenues in the mobile communications market, focusing on changing trends, the impact of innovative technologies on the company's financial performance, also pays attention to the analysis of the number of users of PrJSC Kyivstar, substantiates the factors influencing changes in the number of users, which is an important indicator of the effectiveness of strategies aimed at attracting and retaining customers. The influence of the number of users on the financial indicators of net profit from the sale of services is determined, which allows to assess the financial stability and profitability of the company in a turbulent environment associated with the martial law in Ukraine and the occupation of territories. For a deeper analysis of the strategic positioning of the enterprise, the modified SPACE-analysis method and SWOT-analysis were applied. SWOT analysis allows to identify the strengths and weaknesses of the organization, as well as opportunities and threats from the external environment and takes into account the specifics of innovation processes, such as the introduction of new technologies, changes in consumer needs, new market opportunities and changes in the direction of specialization.To develop the SPACE model, the main factor was the high level of technological development of the company, which is the basis for Kyivstar's leading position in the market, so a model for developing the strategic direction of the enterprise's development based on a modified SPACE analysis matrix was proposed. SPACE-analysis is an important tool in assessing the strategic position and actions, which includes a reflection of external factors (attractiveness and sustainable scientific and technical development of the mobile communications industry) and internal factors (investment and innovation potential of the company). This methodology is used to evaluate strategic plans and processes, which is complemented by a SWOT analysis, which ultimately determines the strategic position of PrJSC Kyivstar in the oligopoly mobile market in Ukraine. The article is a useful resource for specialists in the field of strategic management and analysis of the telecommunications market, as well as for anyone interested in innovative business development in the context of globalization and digitalization.
Sunscreen Cost and Its Effect on Skin Cancer in Low-Income Communities: A Systematic Review
Authors: Sauer John
Published: December 2024

This research examines the pivotal connection between sunscreen affordability and its impact on skin cancer prevalence, especially in low-income communities. Despite universal dermatological recommendations for daily sunscreen use, stringent criteria contribute to elevated prices, averaging around $10 for a 6 oz unit. This financial strain is compounded for families adhering to recommended application rates, leading to significant economic burdens. Outdoor laborers, less likely to follow guidelines, face heightened risks. Government programs' excluding sunscreen costs further exacerbate challenges for low-income communities, contributing to increased skin cancer incidence. This review aims to establish a correlation between sunscreen cost and skin cancer rates, emphasizing the potential to prevent deadly cancers and mitigate post-diagnosis financial burdens. The research methodology involves a systemic review, analyzing sunscreen usage patterns, and correlating them with skin cancer incidence, independent of racial factors. The ultimate goal is to collaborate on strategies for affordable sunscreen access and community education, contributing to a tangible reduction in skin cancer instances in low-income communities.
Spontaneous Intracranial Hemorrhage in a 29-Year-Old Male: A Case Report
Authors: Fateha MD , Nguyen Caroline , Morris Michael A
Published: December 2024

Spontaneous intracranial hemorrhage is rare, especially in a young patient population. Signs and symptoms of intracranial hemorrhage include facial droop, vision loss, motor deficits with extraocular movements, deficits with tongue movement, weakness in the arms or legs, sensation loss, and mental status change. This is a case report of a 29-year-old male with no past medical history who presented for a spontaneous intracranial hemorrhage. This patient's only neurologic deficit was the loss of visual field on the left inferior quadrant of his field of vision. The patient obtained a CT head non-contrast which showed 21 mm acute right occipital hemorrhage medially with mild surrounding vasogenic edema. The patient’s blood pressure was lowered with a blood pressure goal of less than 160 systolic blood pressure with a nicardipine drip of 5 mg/hr. The patient was admitted to the intensive care unit for further management of intracranial hemorrhage and neurosurgical evaluation. This case report helps to educate medical providers on the importance of a thorough neurologic exam and the possibility of an intracranial hemorrhage occurring despite age.

Published: December 2024

The issue of measuring the difference in gravitational potentials and the corresponding difference in orthometric heights based on two spatially separated highly stable ground-based hydrogen quantum clocks is investigated. The relevance of the presented study and its practical significance are determined, in particular, by the prospects for measuring the difference in orthometric heights using the duplex method of comparing the time scales of remote consumers via a geostationary communications satellite. The problem of determining the difference in gravitational potentials and the corresponding difference in orthometric heights between points on the Earth's surface is considered. A solution is proposed for measuring the difference in orthometric heights using the duplex method of comparing time scales of remote consumers via a geostationary communications satellite. A scheme of an original experiment is described for measuring the difference in gravitational potentials and the corresponding difference in orthometric heights based on two spatially separated highly stable ground-based hydrogen quantum clocks. In accordance with the proposed scheme, for the first time in the Russian Federation, the difference in gravitational potentials and orthometric heights of ground points located at a distance of 825 m from each other was measured based on the duplex satellite method and transportable quantum hydrogen clocks. The domestic geostationary satellite Express-80 was used in the geostationary repeater satellite; duplex communication was established using stationary and relocatable sets of duplex equipment. With a relative instability of quantum clocks of 10–15 and a difference in orthometric heights of about 21 m, the measurement error was 2.8 m. The results obtained are relevant for geodetic gravimetry when solving problems of constructing a unified altitude base using highly stable quantum frequency standards.
