Authors: N’Gatta Prisca , Mian Dehi Boston , Angoi Virginie , N’Guessan Koffi , Boni Serge
Published: August 2023

Background: Dysmenorrhea is the most common pelvic pain phenomenon during menstruation in women of reproductive age, and is often characterized by social, educational, and economic impact. The objective of the study is to update the epidemiological and clinical characteristics of dysmenorrhea in a university setting, in a low- and middle-income country (LMIC). Methods: A prospective longitudinal descriptive study, over 6 months, conducted in three university residences in Cocody, Abidjan, the capital of Côte d’Ivoire. It involved female students of all levels of study, present at the time of the survey, volunteers and suffering from menstrual pain for more than 12 months, with an intensity higher than 3 on the visual analog scale (VAS). Pain intensity was divided into mild (1–3), moderate (4–5), and severe (7–10) on the VAS. Students with unstable psychological status or with a disability were not included. After obtaining administrative approval from the university, the questionnaire was administered. The parameters studied were general data and specific characteristics of dysmenorrhea. Statistical analysis was performed using EPI INFO 3.5.4 software (Center for disease control and prevention (CDC), Atlanta, GA, USA). Results: The incidence of dysmenorrhea was 79.7%, with an average age of 23.40 years and a median age of 23 years. These students were aged between 20 and 35 (75%), and participated in undergraduate courses (55.8%). The main form of dysmenorrhea was primary (74.2%), the pain location was pelvic (42.3%) or diffuse (53.1%), protomenial (51.2%), severe pain (56.9%), and torsional pain (44.2%), which affects school activities, with an average duration of 3.49 days. Conclusions: Dysmenorrhea is a common disease among women of childbearing age, and due to social and cultural considerations, it may be underdiagnosed in low resources countries. Due to its diverse symptoms, it has a negative impact on the quality of life, leading to a decrease in enrollment rates.

Background: Complex surgical plans and consideration of risks and benefits often cause decisional conflicts for decision-makers in aortic dissection (AD) surgery, resulting in decision delay. Shared decision-making (SDM) improves decision readiness and reduces decisional conflicts. The purpose of this study was to investigate the impact of SDM on decision quality in AD. Methods: One hundred and sixty AD decision-makers were divided into two groups: control (n = 80) and intervention (n = 80). The surgical plan for the intervention group was determined using patient decision aids. The primary outcome was decisional conflict. Secondary outcomes included decision preparation, decision satisfaction, surgical method, postoperative complications, actual participation role, and duration of consultation. The data were analyzed with SPSS 26.0 (IBM Corp., Chicago, IL, USA). p < 0.05 was considered statistically significant. Results: The decisional conflict score was significantly lower in the intervention group than in the control group (p < 0.001). The decision preparation and decision satisfaction scores in the intervention group were significantly higher than those in the control group (p < 0.001). There were more SDM decision-makers in the intervention group (16 [20%] vs. 42 [52.50%]). There was no statistical significance in the choice of surgical, postoperative complications, duration of consultation, and hospital and post-operative intensive care unit stay time (p = 0.267, p = 0.130, p = 0.070, p = 0.397, p = 0.421, respectively). Income, education level, and residence were the influencing factors of decision-making conflict. Conclusions: SDM can reduce decisional conflict, improve decision preparation and satisfaction, and help decision-makers actively participate in the medical management of patients with AD without affecting the medical outcome.

BEND3 is differentially expressed in central nervous system metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: August 2023

Metastasis to the brain occurs in a significant fraction of patients with breast cancer (1-3). We mined published RNA-sequencing and microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that BEN domain-containing 3, encoded by BEND3, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. BEND3 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of BEND3 in primary tumors was correlated with patient distant metastasis-free and recurrence-free survival. Modulation of BEND3 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.

Published: August 2023

The rapid expansion of digital connectivity has provided youth with near universal access to digital platforms for communication, entertainment, and education. This unprecedented access to digital devices continues to raise concerns about online safety, data privacy, and cybersecurity. The critical factor influencing the ability of youth to navigate digital platforms responsibly is digital literacy. While some regions across the world have implemented digital literacy programs, inequities and disparities remain in not only overall digital literacy levels, but also evaluation of digital literacy. To address these challenges, an environmental scan was conducted to identify existing digital literacy programs in Canada developed specifically for youth, as well as digital literacy assessment tools. The literature search encompassed peer-reviewed articles, organizational curricula, and assessment measures indexed in various databases. Data was synthesized from identified programs and assessment tools to inform the development of a new digital literacy program, and an assessment tool tailored for youth. The environmental scan identified 15 digital literacy programs targeting various components such as data safety, cyberbullying, and digital media. Based on the findings, a new program was developed focusing on four key components: 1) digital fluency, 2) digital privacy and safety, 3) ethics and empathy, and 4) consumer awareness. Additionally, 12 assessment tools were identified for digital literacy focusing on evaluating several aspects, including searching and processing digital information and digital safety, which informed the development of an assessment tool to complement the new program.Tailored digital literacy programs and assessments are crucial for understanding and addressing digital literacy among youth globally. This program's adaptability allows for customization to various target audiences, including culturally diverse and geographically remote communities, to enhance digital literacy across settings. Implementing digital literacy programs can better prepare youth for an increasingly digital world, while minimizing potential risks associated with technology use.

Published: August 2023

The hypothalamus, a diminutive yet vital neuroanatomical structure, plays a central role in integrating external (e.g., environmental) and internal (e.g., physiological/hormonal) stimuli that, in turn, govern diverse physiological processes and shape cognition, emotion, and behavior outcomes. It also establishes the functional connection between the nervous and endocrine systems, upholding homeostasis and coordinating bodily functions. Recent functional advancements in the neurobiology of the hypothalamus unpinned its functional map and established a causal relationship between physiological processes or its responses, including respiration, sleep, and stress, with the hypothalamus. Mechanistically, the hypothalamus facilitates and coordinates the aforementioned complex processes by integrating and processing these diverse stimuli mix and therefore enabling the body to maintain internal balance and respond efficiently to external demands, promoting overall well-being and adaptability. Targeted induced external stimuli could exert specialized tuning of the hypothalamic neuronal activities, and hence could modulate the physiological, cognitive, and emotional landscape. This comprehensive review aims to thoroughly discuss the intricate functional connections between the hypothalamus, cognition, emotion, and physiology and the cross-talks between them. We also briefly elaborated on non-invasive techniques, such as controlled breathing exercises, optimized sleep architecture, and stress management, as potential means to empower the hypothalamus, fostering well-being and cognitive enhancement. In conclusion, this comprehensive review consolidates the multifaceted role of the hypothalamus in integrating signals, maintaining homeostasis, and influencing cognition, emotion, and physiology.
Data Analysis on the Equilibrium Constant of Membrane Configuration Changes in the Human Body Yields Significant Results
Authors: Chaturvedi Archit
Published: August 2023

The general equilibrium constant of a membrane configuration change can be found through the use of a mathematical formula derived through the use of the Metropolis Algorithm. In this paper, I perform a linear and polynomial regression analysis with a degree n = 3, correlating the change in enthalpy of the configurations of the cell membrane with the equilibrium value. I also determine the polynomial function expressed in standard form, the coefficient of correlation, and R2 value. Through this, I propose that the change in enthalpy and equilibrium constant K for the states of a cell membrane present a near-linear relationship, and the linear equation and polynomial derived based on the analysis can be used to approximate the equilibrium constant for the states of a cell membrane in the human body based on the change in enthalpy, and vice versa.

Metastasis to the brain occurs in a significant fraction of patients with breast cancer1-3. We mined published RNA-sequencing and microarray data4,5 to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with brain metastasis in humans with metastatic breast cancer. We found that thioesterase superfamily member 6, encoded by THEM6, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. THEM6 mRNA was present at increased quantities in brain metastatic tissues as compared to primary tumors of the breast. Expression of THEM6 in primary tumors, however, was not correlated with patient distant metastasis-free survival. Modulation of THEM6 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with metastatic breast cancer.
Association between yoga and physical activity among Indian children and youth: a culturally appropriate path to reduce the burden of non-communicable diseases in the global south

Published: August 2023

Physical activity's role in reducing non-communicable disease risk in children and youth is well established. Incorporating yoga, an ancient practice that originated in India, can be a culturally-appropriate strategy to promote physical activity in India. However, there is little evidence of the relationship between yoga practice and physical activity. This study aims to understand how yoga practice is associated with moderate-to-vigorous physical activity (MVPA) among children and youth in India. Data for this study were obtained during the Coronavirus disease lockdown in 2021. Online surveys capturing MVPA, yoga practice, and demographic characteristics, were completed by 5 to 17-year-old children and youth in partnership with 41 schools across 28 urban and rural locations in five states. Linear regression analyses were conducted to assess the association between yoga practice and MVPA. After controlling for age, gender, and location, yoga practice was significantly associated with MVPA among children and youth (β = 0.634, p < 0.000). These findings highlight the value of culturally appropriate activities such as yoga, to promote physical activity among children and youth. Yoga practice might have a particularly positive impact on physical activity among children and youth across the world, owing to its growing global prevalence.
Redefinition of new physics philosophical principles for explaining motion phenomenon
Authors: Dalir Mohammad Asadi
Published: August 2023

In this research, the author attempts to make a fundamental revision on the Newtonian mechanics to provide a new theory having a more diverse range of phenomena explained. It is proposed that the first and second laws are reformed and the third one is held while the general law of gravity has been removed. The basic concepts of Newtonian mechanics are location, mass and absolute time. The absolute time being held, mass is included as a more general concept and location is not an original concept, but a second order one. Motion in 3D frame is considered to be an inherent property for 3D objects and location is its integration. On the other hand, location for light as a 4D object is not sensible. The free fall phenomenon is described without using Newton’s general law of gravity. The well-known experimentally verified results of relativity theories (special and general) are covered by three postulations of the new theory. The gravity is a result of Ether’s motion as a fluid among cosmological masses and the accelerating expansions of galaxies as well as the fast motion of objects in the galaxies margin are shown to be explainable without needing some unknowns such as dark energy and dark matter. The philosophical aspects of new theory are analyzed at the end.

This chapter reviews the motivations, challenges and benefits, and practical considerations of conducting replication studies in the field of second language acquisition (SLA) with a focus on quasi-experimental designs. The chapter begins by describing what replication research is, what the most common types of replication research are, and why carrying out replications is both important and needed. This is followed by an overview of some the challenges to doing replication research in SLA. In the “How to” section, step by step guidance is provided for addressing approaches to variable modification in the planning and design of replication studies, which represents a key challenge to publishing high-quality replication studies in SLA. A recurrent theme in this chapter is highlighting the specific contribution of quasi-experimental replication studies to knowledge and understanding in the field. Recommendations for future quasi-experimental replications in SLA are suggested as well ways in which researchers can integrate replication into future programs of research.
Sea Ice Loss, Water Vapor Increases, and Their Interactions with Atmospheric Energy Transport in Driving Seasonal Polar Amplification
Authors: Chung Po-Chun , Feldl Nicole
Published: August 2023

The ice-albedo feedback associated with sea ice loss contributes to polar amplification, while the water vapor feedback contributes to tropical amplification of surface warming. However, these feedbacks are not independent of atmospheric energy transport, raising the possibility of complex interactions that may obscure the drivers of polar amplification, in particular its manifestation across the seasonal cycle. Here, we apply a radiative transfer hierarchy to the idealized Isca climate model coupled to a thermodynamic sea ice model. The climate responses and radiative feedbacks are decomposed into the contributions from sea ice loss, including both retreat and thinning, and the radiative effect of water vapor changes. We find that summer sea ice retreat causes winter polar amplification through ocean heat uptake and release, and the resulting decrease in dry energy transport weakens the magnitude of warming. Moreover, sea ice thinning is found to suppress summer warming and enhance winter warming, additionally contributing to winter amplification. The water vapor radiative effect produces seasonally symmetric polar warming via offsetting effects: enhanced moisture in the summer hemisphere induces the summer water vapor feedback and simultaneously strengthens the winter latent energy transport in the winter hemisphere by increasing the meridional moisture gradient. These results reveal the importance of changes in atmospheric energy transport induced by sea ice retreat and increased water vapor to seasonal polar amplification, elucidating the interactions among these physical processes.
Collaborative learning in older age and the role of familiarity: Evidence from the Map Task

Published: August 2023

As we age, learning new knowledge and skills becomes more difficult due to age-related changes to cognition. Learning collaboratively could counteract these changes, and perhaps more so when working with someone familiar. This study examined whether collaborative learning is affected by age and partner familiarity. Forty-eight participants (younger n = 24, older n = 24) completed the Map Task with a familiar and unfamiliar same-age partner. Participants became more efficient at completing the Map Task over time, regardless of age and partner familiarity. There was no age difference in immediate or 1-hour recall, but younger adults recalled more after 7 days than older adults. Overall, results suggest that collaborative learning outcomes are unaffected by age or partner familiarity, and that collaborative learning has short-term protective effects on memory, with age-related declines only emerging after 7 days.
Being a round /y/: An acoustic description of high front vowels in Singapore Mandarin elicited by speakers with different bilingual balance in Mandarin and English
Authors: Pan Lei , Moisik Scott R , Styles Suzy J
Published: August 2023

In acoustic phonetics, there is limited research about individual differences among bilinguals with different language balances. Using a picture description task, we recorded 942 vowel tokens of high front vowels from Singaporean adult bilinguals of Mandrin Chinese and English (N=50, 25 female). F1, F2 and F3 frequencies were tracked for /y/ (phonemic in Mandarin Chinese) and /i/ (phonemic in English and Mandarin). Generalized additive mixed models were used to characterise formant trajectories of /y/ and /i/ over the timecourse of articulation, with smooth terms of vowel, gender, tone and phonemic context. F1 was similar throughout articulation for both vowels. Formant trajectories differed across the whole timecourse for F2, and in the final stage for F3. Furthermore, we observed that speakers’ bilingual balance influenced the degree of difference between /y/ and /i/ for a given speaker, with larger differences in F3 (the psychoacoustic correlate of lip rounding) for those with more Mandarin in their bilingual balance. These findings demonstrate that three-dimensional formant trajectories are a valuable way to investigate nuanced acoustic profiles, and that language histories can be considered a powerful addition to our understanding of individual differences within a multilingual community.
Disentangling Genetic and Social Pathways of the Intergenerational Transmission of Cognitive Ability – A Nuclear Twin Family Study
Authors: Wolfram Tobias , Ruks Mirko , Spinath Frank M.
Published: August 2023

As cognitive ability accounts for large parts of the intergenerational transmission of advantage, it is crucial to understand the mechanisms driving the intergenerational transmission of cognitive ability itself. Social mobility research usually focuses on social mechanisms of intergenerational transmission. For the case of cognitive ability, this means that parental cognitive ability affects offspring ability via the family environment. However, parents do not only provide resources, but also pass their genes to their children. As social and genetic transmission are not mutually exclusive, it is crucial to disentangle the contribution of both to the intergenerational transmission of cognitive ability. Using data from the German TwinLife survey, we apply a nuclear twin family design to address this question. Using data from all four twin birth cohorts, covering an age range from 5-25 years, we further explore whether the contribution of both mechanisms varies over the life course. For all four cohorts, in any of the estimated models, social transmission is very small and not significant. Genetic transmission, in turn, seems to be the primary mechanisms of intergenerational transmission of cognitive ability and becomes increasingly important with age. Our findings challenge conventional social mobility perspectives, stressing the need to incorporate genetic transmission into sociological research for a more comprehensive understanding of intergenerational transmission of advantage.
Young Authors & the Anthropocene: What story books reveal about the place-ecological meaning constructed by children of the global south

Published: August 2023

This qualitative research conducted in 2020 examines 14 Indian children’s place-ecological meaning as expressed in the story books they authored. Thematic analysis of the story books, interviews, journals, creative writing assignments & group discussion revealed that the children’s outdoor nature experiences shaped their place-ecological meaning and inspired a striking critique of the necropolitical-geontopolitical Anthropocene regime in local contexts. Children’s sense of marginalisation forged empathy with the more-than-human, fostering feelings collective identities and resistance, despite muted agency. The research emphasizes that environmental education program should not only build awareness and conscientization among participants but also provide opportunities for expression of meaning-making. The significance of the research lies in it bringing the unheard voices of children in the Global South to the fore as they attempt to examine the Anthropocene from their experiences of local ecologies and places in Chennai, India.

Published: August 2023

The expansion and growth of Higher Education in Indonesia are very rapid with a large population, large area, and dense activity, resulting in significant waste generation. This study was to analyze and plan waste management according to the green campus concept. This research uses a descriptive explorative with a case study strategy at Universitas Respati Yogyakarta. The sample is all waste generated in the campus and the research instrument uses 2 guidelines: measurement of waste generation and composition refers to the SNI and waste management analysis based on guidelines from UI GreenMetric. The results showed that the generation and volume of waste were above the SNI values. The waste containers provided do not meet SNI: volume, number, color, and several waste collection tools. The campus has a program to reduce the use of paper and plastic, but it has not been maximized because there is no recycling program, >75% of organic waste has not been handled, there is no handling of B3 waste and the method of disposing of liquid waste is still conventional. The conclusion is that handling waste on site is a step that must be carried out before being disposed of in a container.

Published: August 2023

Kinematics analysis includes analysis of position, velocity and acceleration of the rods of a mechanism. The complex number method is a kinematic analytical way to express position, velocity and acceleration vectors in the form of complex numbers. The first step that needs to be done is to determine the position vector of the point to be analyzed, then determine the velocity and acceleration vectors by differentiating with time. After that is done, then the algorithm can be made. The mechanism used for this study is the quick return mechanism. The assumed data for this analysis is the angular velocity of rod 2 is 19.0986 rpm and the acceleration of rod 2 is 0 rad/s2. The results of the position analysis show that if rod 2 rotates one full rotation (360o), then rod 4 rotates about 1/6 circle (232.72o - 294.12o) and the slider moves along the X axis (406.939 - 504.111). The maximum speed behind the slider is 121.45 mm/s while the maximum speed forward for the slider is 101.09 mm/s. A large change in velocity (acceleration) is needed when bar 4 and the slider change direction (from CW to CCW or vice versa), this is indicated by a decrease and increase at the beginning and end of the graphic with significant acceleration

Chinese citrus fly is the major pest of sweet orange in citrus growing districts of Bagmati Province Nepal. Farmer’s production constrains and production problems such as Chinese citrus fly problem in sweet orange are not well documented and studied. This study was conducted in Sindhuli, Ramechhap, Dolakha and Kavre districts of Bagmati Province in 2021 with aim to understand the farmer’s perception, knowledge about CCF and their management practices using semi-structured questionnaire. Collected survey data was analyzed using the SPSS-20 and MS Excel. The survey results depicted that the intensity of Chinese citrus fly damage has been decreased in Sindhuli district with the infestation level of < 20% in sweet orange orchard. However, CCF population as well as their damage level was in increasing trend of > 50% in sweet orange orchard in Ramechhap, and > 80% in Dolakha and Kavre district. Chinese citrus fly loss has been recorded up to 25% in Mandarin orange in Dolakha and Kavre district. Maximum Chinese citrus fly loss was recorded in sweet orange orchard in October month. Farmers usefully managed the dropping fruits by collecting in plastic bags and burying in pits. Great fruit fly bait, has been used for the CCF management in three districts except in Kavre. Majority of farmers reported that chemical pesticides are less effective or sometime not-effective for this pest management. This study provides a preliminary information about sweet orange orchard management practices, general pest problems, Chinese citrus fly and future management strategy in survey districts.
Molecular Interactions of Zinc Finger Protein Kaiso with Hemimethylated DNA
Authors: Thapa B. , Adhikari N. P.
Published: August 2023

DNA methylation is an epigenetic modification that is involved in various essential cellular processes. Methyl CpG binding proteins (MBPs), such as zinc finger protein Kaiso, bind with methylated DNA and mediate to translate methylation signal into the transcription process. To have mechanistic understanding of how these proteins recognize and interpret the DNA methylation signal is important because of their critical role in regulation of gene expression in both normal and diseased cells. In this study, we performed molecular dynamics (MD) simulation to investigate the recognition and binding of hemimethylated (methylation in one strand of double stranded DNA) sequences by Kaiso to assess the role of methylation in each strand. We investigated the major interactions involved in the complex formation as well as the contact area and binding free energy of the Kaiso-DNA complexes. Our results show that the number and strength of hydrogen bonds as well as other non-bonded interactions are greater in Kaiso-DNA complex with methylated CpG sites in non-coding strand. Similarly, the contact area at the Kaiso-DNA interface and binding free energy of Kaiso is also higher in hemimethylated sequence having methylation in non-coding strand. Therefore, methylated CpG sites in non-coding strand play important role in the binding of Kaiso with methylated DNA sequences.

Electronic and magnetic properties of materials are appealing properties and have budding applications in the devices. In this work, we have investigated the structural, electronic and magnetic properties of pristine Zinc-Oxide (ZnO) and Oxygen-defected Zinc-Oxide (ZnO_O) materials by spin-polarized density functional theory (DFT) method. Structural properties are studied by calculating their total ground state energy, and found that both are stable 2D materials. It is also found that ZnO have higher stability than of ZnO_O material. Electronic properties of considered materials are examined by analyzing of their band structure, density of states (DOS) calculations and found that ZnO is a direct band gap, n-type semiconductor material in its pristine form and an indirect band gap, p-type semiconductor material in its Oxygen-defected form (ZnO_O). Magnetic properties of pristine and defected ZnO are investigated by analyzing their density of states (DOS) and partial density of states (PDOS) calculations, they revealed that ZnO and ZnO_O have non-magnetic properties.

Published: August 2023

The COVID-19 pandemic has led to a significant increase in the production and use of disposable face masks, contributing to the growing global waste problem. While face masks were initially used primarily by healthcare professionals who knew how to dispose of them properly, their widespread adoption by the general public has raised concerns regarding the correct management of discarded masks. This issue is particularly significant as new types of pollutants, including microplastics, are being introduced into the environment. In underdeveloped nations like Nepal, misconceptions about the composition of face masks and a lack of awareness about their environmental impact are prevalent. To gain insight into the particle constituents of commonly used face masks, namely normal, surgical, and KN95 masks favored by residents of Nepal's Kathmandu Valley, we conducted Fourier Transform Infrared Spectroscopy (FTIR) analysis using an IRTracer-100 spectrometer. Our analysis identified the functional group and revealed that the primary material found in these masks is polypropylene microplastic polymers, rather than biodegradable fibers.

Persistent Organic Pollutants (POPs) merupakan senyawa organik yang dapat bertahan lama di lingkungan (persistent) serta mempunyai sifat toksik bagi makhluk hidup. Jika senyawa ini dikonsumsi terus-menerus oleh masyarakat, maka akan menimbulkan masalah serius yang memiliki dampak negatif bagi lingkungan dan kesehatan. Pada artikel review ini, dibahas dampak yang disebabkan oleh POPs terhadap lingkungan dan kesehatan. Metode yang digunakan yaitu metode naratif. Teknik pengumpulan data secara kajian literatur dilakukan secara luas menggunakan search engine, yaitu Google Scholar, ScienceDirect, dan American Chemical Society. Pada lingkungan, senyawa ini dapat menyebabkan pemanasan global, perubahan iklim, perubahan penggunaan lahan akibat emisi pestisida organoklorin, perubahan ekologis, dan lain-lain. Dampak lain juga dapat ditimbulkan terhadap kesehatan, seperti kanker, obesitas, penyakit reproduksi dan neurologis, diabetes, dan lain-lain. Oleh karena itu, akademisi dan ilmuwan harus mengevaluasi lebih lanjut model yang berbeda untuk menentukan berbagai aspek POPs sehingga senyawa ini di masa depan dapat diturunkan risiko-risiko berbahaya yang ditimbulkannya.

On the concept of intellectual rights in the light of their object
Authors: Ovchinnikov Ivan
Published: August 2023

This article explores the concept of intellectual rights, introduced by Part 4 of the Civil Code of the Russian Federation to denote the totality of intellectual property rights. The author argues its independence among subjective civil rights not only from property rights, but also from the rights of personality. The development of European Civil Law of the XIX century that led to steady decline of the proprietary theory of intellectual property, simultaneously led to the formation of the theory of personality rights in relation to artistic work. This theory, which understood the work as a continuation of the author’s self, still exerts its influence upon Russian Civil Law and leads to the confusion of intellectual property with inalienable attributes of personality (intangible goods) in the system of objects of civil rights.

Features of the formation of political and legal subjectivity of modern Russia S. Shakhray. How I wrote the Constitution of the Yeltsin and Putin era
Authors: Khabibulin Alik G.
Published: August 2023

The features of an autobiographical narrative allows the reader to trace not only the main stages of the life path of the hero of the story, but also to get a more complete picture of the events of the past, when the desire inevitably arises to agree, and in some ways disagree with the author’s vision and perception of events, people, features of the formation of new foundations of Russian statehood. The rather voluminous narrative of the author about the work of the First Congress of People’s Deputies of the RSFSR, where he was elected chairman of the Committee of the Supreme Soviet of the RSFSR on legislation, deserves attention. By virtue of his position, he also became a member of the Presidium of the Supreme Soviet of the RSFSR, which was headed by B.N. Yeltsin. Constant communication with the head of the Russian parliament helped to form a clear idea among the author of the memoirs and his colleagues, which made it possible to convince B.N. Yeltsin of the need to adopt the law on a referendum as the first practical step of the new parliament. It is obvious that such a decision made it possible to overcome many negative consequences that were the result of unprecedented political processes that took place in society in the early 1990 s. in the last century. The creation of a mechanism for holding referendums allowed the head of state to largely maintain control over the development of the situation in the country. We note the simple language of narration that is accessible to the reader, the book contains the author's assessments of legal battles that are tough in their content, emotionally colored political clashes, capacious, but at the same time objective characteristics of statesmen and public figures are given. It can be said that the author, with his work, became a forerunner for those who dare to write such memoirs, especially when it comes to such a difficult period, which began with the events of thirty years ago
