Published: March 2023

Telangana state's population is mostly dependent on agriculture. The Telangana state's economy depends heavily on agriculture, as does the nation's and the state's ability to achieve food security. Combining art and science to fit a statistical distribution to data involves making trade-offs along the way. The secret to effective data analysis is striking a balance between improving distributional fit and preserving ease of estimation while keeping in mind that the analysis's ultimate goal is to help you make better decisions. A recurring issue in agricultural research was which distribution should be utilized to simulate the production data from an experiment.

An analysis is then carried out utilizing the obtained distributions using the statistical method to fit probability distributions to data of variables. These distributions would be a representation of the properties of the variable data. The twenty distributions are: Cauchy, Error, Hypersequent, Gamma(3p), Laplace, Logistic, Log Pearson 3, Rayleigh (2p), Weibull (3p), Log Logistic (3p), Triangular, Gen Gamma, Gen.Gamma(4p), Gen.Extreme Value, Log Normal (3p), Pearson 5 (3p), Fatigue life (3p), Inv. Gaussian (3p), Nakagami, In order to suit a distribution research, rice distributions are used. Twenty probability distributions were computed, and the test statistic Kolmogorov-Smirnov test, Anderson-Darling test, Chi-Square test, and each data set were used to choose the distribution that fit the data the best. The probability distributions include Cauchy, Error, Hypersequent, Gamma, Laplace, Logistic, Log Pearson 3, Rayleigh (2p), Weibull (3p), Log Logistic (3p), Triangular, Gen. Gamma, Gen. Gamma (4p), Gen. Extreme Value, Log Normal (3p), Log Pearson 5, Fatigue life (3p), Inv. Gaussian (3p), and Nakagami.

Published: March 2023

The growing evidence favoring the positive effect of exercise on cognition is mostly based on men participants (75%). We therefore exposed females and males to acute exercise and evaluated gender cognitive response to this intervention.
Thirty- two adults (M=17; F=15) ages 18-34 participated in the study. The exercise consisted of ten repetitions: 10 seconds sprints at maximal speed, followed by 50 seconds active recovery. Stroop test (ST) 1-3; Trail-making test (TMT) 1-2; Word fluency were evaluated prior to; immediately post exercise; and at 45’ recovery. Two-way ANOVA with repeated measures (three test points X 2 gender groups) was used to test the effect of exercise on cognitive performance.
All participants reached close to maximal heart rates at the end of the 10th sprint round. Stroop 1- 2 results improved for both males and females from pre to post exercise (p<0.01). After 45’ males returned to pre-exercise while females retained high values. For Stroop 3 both genders improved from pre to post (p<0.01) and retained high values after 45’. For TMT-1 males showed no response while females’ results improved immediately and at 45’ post intervention (p<0.01). For TMT-2 both genders improved after exercise (p<0.01); however, only females continued improving at 45’ recovery. Word fluency was positively affected by exercise in males only.
Acute bout of exercise has a positive immediate effect on cognitive performance both in males and females; whereas males returned to pre-intervention values at 45’ min recovery, females retained the positive effect of exercise also after 45 minutes.

Published: March 2023

Severe complex deformities of the forefoot in elderly patients with no rheumatoid arthritis result in the pronounced decrease in quality of life, chronic pain, reduced mobility, failure to get shoes for everyday use, exacerbation of the concomitant somatic diseases. The use of conventional joint preservation techniques in such patients often leads to the deformity relapse, persistent pain, and the need for revision surgery that is often impossible due to worsening of the patients' general somatic status and local functional status. The study was aimed to improve surgical outcomes in elderly patients with no rheumatoid arthritis who had severe forefoot deformities. The prospective cohort study that involved allocation to the retrospective group for comparison of surgical outcomes in 65 patients was carried out in 2016–2019. The results obtained before and after surgery were assessed using the FFI, AOFAS Hallux, and AOFAS Lesser Toes scores. The Maryland scores were used to assess the outcomes during the postoperative period. The study revealed significant differences in treatment outcomes based on the AOFAS Hallux (p = 0.0001), AOFAS Lesser Toes (p = 0.0001), FFI (p = 0.0001), and Maryland (p = 0.0001) scores. In view of the elderly patients' specific nature, the radical surgical techniques that do not ensure joint preservation may be considered as effective and predictable methods of correction aimed at reducing the rate of revision surgeries. These techniques represent a one-step method to improve the quality of life of elderly patients.

Today, the issue of preservation, maintenance and development of mental performance is of great importance due to social transformation and the school and higher education system upgrade. The growing body of information, continuous modernization of the training programmes, the use of various technical training aids that result in intensification of cognitive activity have a negative impact on the students' mental state. The study was aimed to assess the medical students' mental performance indicators in relation to the time of the day and the daily fluid intake. A total of 300 students were enrolled, who had both morning and afternoon (after lunch) classes. Mental performance of medical students was assessed using the Anfimov's table. It was found that the students' mental performance depended not only on the start time, but also on the water consumption regime. The main trends of water consumption in young adults were defined: moderate water consumption (1–2 L per day) prevailed, low water consumption (less than 1 L per day) was ranked second, and high water consumption (more than 2 L per day) was the rearest.

Published: March 2023

This paper presents the results of estimating the population density and abundance of Ursus arctos (hereinafter – brown bear) in the Southern Forestry of the Central Forest State Nature Biosphere Reserve (CFNR), West of European Russia, in 2021 based on the Random Encounter Model (REM) based upon data obtained from camera traps. Methods for obtaining parameters necessary for building a model are demonstrated. A total of 7970 camera trap nights were worked out at 46 stations, and 502 independent trap events were obtained. The average relative abundance index (RAI) was 6.28 ± 1.59. The total average brown bear population density was 0.086 ± 0.034 individuals per 1 km2. The approximate estimated abundance was 18.98 ± 7.54 individuals. The coefficient of variation was 38%. Population density estimates had a pronounced seasonal dynamics. The minimum value was recorded for the period from 24 June to 23 July (individuals feeding on meadows and ants outside the CFNR core area), and the maximum for the period from 24 July to 22 August (brown bears feeding by berries in the CFNR core area). We found a strong significant correlation between brown bear population density and its relative abundance index (r = 0.81, p < 0.05). It was found that with an increase in the sampling period duration, the estimate of the population density noticeably decreases (r = -0.53, p < 0.05). Parameters of the average travel speed and activity level are a subject to the greatest variability, which determines the significant variability of the day range. In general, the method of population density estimation using REM is highly promising to carry out the brown bear population size estimation in forests and mountain forests, where visual estimations are difficult or impossible.
Social Partnership as a Method of Legal Regulation of Employment Relations: The Case of Lithuania
Authors: Krasauskas Rytis , Mačernytė-Panomariovienė Ingrida
Published: March 2023

This article assesses the significance of social partnership in the regulation of employment relations. It is pointed out that the legal regulation of employment relations in Lithuania lacks stability, and the hypothesis is raised that this situation has been partly determined by the vanishing, negligible role of social partnership. The presumption is put forward that the regulation of employment relations can result in an effective and sustainable balance between the interests of employees and employers only if the possibilities of social partnership are used to their full extent and an optimal balance is achieved between contractual law-making and state law-making. The Lithuanian social partnership model is defined as gravitating from quasipartnership towards real social partnership; therefore, ways are still being sought as to how to strengthen the impact of social partnership on the regulation of employment relations by means of legislation and the use of soft law. To reveal the impact of social partnership on the regulation of employment relations in Lithuania, the article identifies and assesses the key indicators revealing the influence of social partnership on the regulation of employment relations and examines the positive legal regulation related to social partnership.
The Democratic Legitimacy of Constituent Referendum(s) in Constitution-Making Process Within The Scope of Turkish Constituent Referendum Experiences
Authors: Bagceci Hamide
Published: March 2023

The referendum experiences of each state vary according to their democratic background, development, and welfare level. Accordingly, it becomes hard to adopt a uniformed approach towards the issue and necessitates questioning the democratic value of each practice within itself. Although a referendum is a tool for reflecting the people’s will, it may not necessarily take place in every case. Constituent referendums differ from other types of referendums in that the constituent power is not bound by any rule of law. In view of this, the democratic value of the constituent referendum has been chosen to be examined in this article, rather than the democratic value of referendums in general.

This article focuses on the relationship between the constituent referendum and democracy as a basis and questions whether constituent referendums are indeed a genuine tool of democratic constitution-making and whether they are sufficient to secure democratic legitimacy for the constitutions. Despite the fact that at first glance, constituent referendums tend to have their sights on a democratic goal, the practices reveal that the outcome is not necessarily in accordance with the intended goal. Particularly, the adoption of the 1961 and 1982 Turkish Constitutions has shown that this method is not sufficient in terms of ensuring democratic legitimacy. Therefore, the issue has been evaluated specifically in relation to the constituent referendums that ensured the adoption of the 1961 and 1982 Turkish Constitutions.

In this study, the relationship between the constituent referendum and the constitutionmaking process is discussed in a theory-oriented manner in the first three sections, and two important case analyses selected from Turkish constitutional law are included in the following sections. As a consequence, it has been concluded that constituent referendums, when held in antidemocratic settings, are incapable of ensuring democratic legitimacy for constitutions and thus are not necessarily a genuine instrument of democratic constitution-making.
Caring about The Caregivers: Challenges for Female Caregivers in Lithuanian and Estonian Labour Law
Authors: Ambrazevičiūtė Kristina
Published: March 2023

While considerable efforts are being made to consolidate and implement the principle of gender equality, the gender pay gap remains a real problem. One of the reasons for this gap is the traditional role of women in caring for children and other relatives. By devoting a significant part of their time to the unpaid care function, women have fewer opportunities to participate in employment relationships. This leads to women’s poorer financial situation, limited career opportunities, and a higher risk of poverty in old age. Therefore, both at the EU and national level, there has been a search for optimal ways to enable female caregivers to remain in the labour market and ensure their income levels. This article provides an overview of the situation of female caregivers and the legal measures taken by Lithuania and Estonia (both EU Member States) to improve the situation of women performing unpaid care functions in labour relationships.
Epieikeia or “Better Justice”: Formalism in Tax Law Revisited
Authors: Filipczyk Hanna
Published: March 2023

For Aristotle, “the essence what is equitable is that it is an amendment of the law, in those points where is fails through the generality of its language”. The application of legal rules produces appropriate (just) results in the majority of cases, but not in all. When its application would lead to injustice, a legal rule can be defeated by equity.

The idea ofepieikeia(equity) sheds light on the modern discussion about the nature of legal rules, the distinction between rules and principles, and mechanisms of adjudication.

This idea is also relevant in the tax law domain. In this area, the dominant theoretical position is legal formalism, with its focus on (strictly conceived) legal rules in legislation and in the application of the law. The Aristotelian reflection onepieikeiaposes challenges to this traditional view: legal rules are deficient, and thus, as demonstrated, so is the formalistic approach to tax law. In particular, the equitable resolution of a tax dispute can be achieved through alternative dispute resolution methods: on the basis of a consensus between a taxpayer and a tax authority that is not strictly based on a legal rule.
Accessibility of Legal Aid to Children in Conflict With The Law: Bringing the General Concept to Practice

Published: March 2023

This paper analyses the concept of accessibility of legal aid for children in conflict with the law, searching for its essential elements in international standards and national practices. By analysing the comparative empirical data on legal regulation in different European jurisdictions, the authors of the paper discuss what it means for legal aid to be accessible to children and what could be done to strengthen it. The paper argues that the goal of improving access to legal aid for children in conflict with the law should be approached from various directions, including the provision of information on legal aid in a child-friendly and age-appropriate manner, the strengthening of children’s legal education, the dissemination of child-friendly materials, and the training and specialisation of legal aid lawyers and other professionals.

Published: March 2023

Forest cleaning, being an operation that requires investment, but the return on investment is due for the next generations, utilizes tools and methods that mostly haven’t been humanized. Harmful vibration is still present in today’s forestry operations, and new tools provide possible reduction of exposure to vibrations. Petrol chainsaw and battery chainsaw (late cleaning) and billhook, machete, and battery shears (early cleaning) were used and observed in this study. Vibration levels were measured and assessed using validated Brüel & Kjær 4447 vibrometer which complies with the ISO 8041:2017 standard. The measurement was performed according to the recommendations of ISO 5349-1:2001 and ISO 5349-2:2001 standards. Vibration exposure was assesed using work sampling method on the obtained video recordings in order to calculate relative shares of different work elements. Results show that hand tools (machete and billhook) are causing the highest vibration levels, while battery shears cause the lowest. Battery chainsaw causes higher vibration levels while cutting, but lower daily vibration exposure than petrol chainsaw. A detailed revision in the classification of tools is needed, considering their ability to produce and transmit harmful vibrations to the operator. Using the current classification, the daily exposure to vibration of workers in early forest cleaning is high above legislative values.

Mosquito is one of insects spreading the vector of serious diseases to human being through its bite such as Culex which spreads the vector of filariasis and brain inflammatory diseases. Some people have used plants as insecticides traditionally, such as fern (Diplazium esculentum (Retz.) Sw.). D. esculentum (Retz.) Sw. popularly known as edible fern which almost all Asian people, especially Indonesian consumed it as vegetable, and some people also used it for medicinal purposes. This study was performed to investigate the secondary metabolites from D. esculentum leaves and its larvicidal activity against Culex. The phytochemical screening was undertaken on the leaves and methanol extract of D. esculentum, the results showed the presence of alkaloids, steroids, phenols, and tannins on leaves, while methanol extract exhibited existence of steroids, saponins, phenols and tannins. Investigation of larvicidal activity of methanol extract was carried out against Culex larvaes for various concentrations which observed for 48 hours. Percentage of mortality was analyzed statistically using Bill Test method that showed active larvicidal activity with a LC50 value of 149.279 ppm. This study indicates that fern plant have the potential as larvicidal against Culex and need to perform the further research to develop the new natural insecticides.

Published: March 2023

A variable selection method is required to deal with regression models with many variables, and LASSO has been the most widely used methodology.  However, as several authors have noted, LASSO is sensitive to outliers in the data.  For this reason, the Robust-LASSO approach was introduced by applying some weighting schemes for each sample in the data.  This research presented a comparative study of the three weighting schemes in Robust LASSO, namely Huber-LASSO, Tukey-LASSO, and Welsch-LASSO.  The study did a rich simulation containing many scenarios with various characteristics on the covariance structures of the explanatory variable, the types of outliers, the number of outliers, the location of active variables, and the number of variables.  The study then found that Tukey-LASSO outperformed Huber-LASSO and Welsch-LASSO in identifying significant variables.  The Robust LASSO performance generally decreased as the covariances among explanatory variables increased and the data dimension increased.  Exploration of sembung leaf extract data shows that the data is high dimensional data which contains outliers of about 14,28% on the response variable and about 25,71% on the explanatory variables.  Based on the research, the number of variables selected using the Tukey-LASSO method was nine compounds, Huber-LASSO and Welsch-LASSO were eight compounds, and LASSO 13 compounds.  The Tukey-LASSO prediction accuracy is superior to the other three methods.

Understanding feral cat behavior can be one of the aspects that is necessary for proper management and taking policy action in controlling the cat population. This study aimed to observe the daily activities of feral cats and see the correlation between the number of visitors on cat-to-human interaction at a canteen in IPB University. Observation of cat’s daily behavior was conducted by scan sampling method and cats’ interaction with humans was conducted by ad libitum sampling. Our results showed that self-care (66.27%) dominated the daily behavior of cats followed by negative behavior (20.83%) and affiliative behavior (12.9%). Correlation test showed there was a significant negative correlation between the number of visitors and frequency of affiliative behavior (p = 0.024). The number of visitors also shows a positive correlation to self-care (p = 0.034). No significant correlation between the number of visitors and negative encounters behavior (p = 0.27). The highest frequency value of cat-human interaction was approaching human (A) 28.15%, followed by vocalization (MV) 28.15% and eye contact (KM) 22.71%. Cat-human interaction behavior did not significantly correlate with the number of visitors (p 0.05). Our result implies that the feral cat’s use the canteen as a place to rest, not a place to find food and daily activities and human-cat interactions were specific for each study site. Therefore, in the management of feral cats, it was necessary to pay attention to the conditions of their respective habitats.

Published: March 2023

Generalized Linear Models (GLMs) are a modeling approach that allows the modeling of nonlinear behaviors and non-Gaussian distributions of residues. This approach is very useful for general insurance analysis, where the frequency of claims and the amount of claims distributions are usually non-Gaussian. In this article, the application of Poisson and Negative Binomial models to estimate the frequency of claims of auto insurance is discussed. The accuracy of the models was compared to choose the best model for determining pure insurance premiums using R software. The data used are a secondary dataset which is the motor vehicle insurance dataset from Sweden named dataOhlsson and the motor vehicle dataset from Australia named ausprivauto0405. The results of the exploration of the GLMs model are that Poisson's GLM and Negative Binomial models both are suitable models for estimating the number of claims for the dataOhlsson dataset. Both models have relatively similar parameter estimates, as well as the AIC and BIC values for the dataOhlsson dataset, however, both models are not suitable for estimating the number of claims for the ausprivauto0405 dataset. More investigation using different models is needed to ensure which model is more appropriate for estimating the frequency of insurance claims.

Solar energy plays an important role in the temperature distribution on the Earth's surface and essential energy that sustains life for human. In the calculation of solar energy, the limitation of solar radiation data is a major obstacle. Solar radiation data is very limited at some observation stations due to the costly procurement of measuring instruments and complicated techniques. Estimation of global solar radiation using empirical models is one way to overcome the limitations of global solar radiation data at various locations. This study built the Angstrom-Prescott model to estimate global solar radiation based on the sunshine duration’s parameter in Aceh Besar Regency. Two years (2019-2020) global solar radiation and sunshine duration data from Aceh Climatological Station were used to estimate global solar radiation in 2021. Data for 2021 was using to evaluated the equation H/H0=0.28+0.22 (n/N), the results showed good model accuracy with an RMSE value of 0.052 and a MAPE of 11% (good forecasting). The model equation has been reliable to calculate solar radiation in four locations in Aceh Besar Regency.

The civil Nature of public-private Partnership Agreements
Authors: Kilinkarov Vladimir Vital'evich , Ponomarev Bulat Askarovich
Published: March 2023

The subject of the research is the legislation and law enforcement practice regarding the legal nature of the public-private partnership agreement and the concession agreement. The authors intend to prove the civil law nature of these agreements; therefore, they review dominant theories on the relevant issue in the doctrine of legal science. The first group of scientists refers these agreements to private-public contracts, the second - to administrative, the third - to private law. The analysis of the legislation confirms the validity of the third group’s point of view. The paper also examines the practice of judicial and administrative authorities, which testifies to the dispositive nature of legal relations arising between private and public partners.

Published: March 2023

The purpose of the study of the article is to consider the legal regulation of the field of pharmacy in the late 17th - early 19th centuries, using the methods of historical heuristics and general statistics. The relevance of studying the problem of legal regulation of pharmacy is due to the fact that, despite the high scientific interest in the history of medicine, as one of the leading areas of interdisciplinary research, there is an extremely limited number of works on the issue under consideration, mainly represented by general lecture courses for medical students. The object of this study is the process of legislative regulation of pharmacy in the late 17th - early 19th centuries. The subject of study is a wide range of normative legal acts presented in the Complete Collection of Laws of the Russian Empire. A special contribution of the authors of the study of the topic is the analysis of more than 150 legal acts (NLA) for the specified historical period. The authors carry out the distribution of the NPAs under consideration according to the subjects of their regulation by the periods of leadership of the country by the Russian rulers. The authors conclude that pharmacy was an important component of legislative activity in the field of legal regulation of healthcare. Directions of regulation within the framework of pharmacy for the period under review cover a wide range: from military pharmacies to determining the behavior of pharmacy students. The formation of pharmacy in Russia has largely developed, as legal sources show, thanks to the imperative norms of the supreme power.

City universities play a leading role in the formation of the educational, socio-cultural, intellectual environment of the city. At the same time, a new paradigm of interaction between universities and citizens is being formed as part of the implementation of the idea of "cities as communities of citizens", when urban communities become full-fledged subjects of city development along with city authorities. In this regard, the subject of the study was to identify the potential of the university in interaction with urban communities. Research methods: survey, focus group interview with elements of brainstorming. The study involved representatives of various urban communities of Moscow (N=170), students, teachers of the Moscow State Pedagogical University (N=358).      The results of the study. The priority areas of interaction between university campuses and urban communities can be identified as: educational (counseling and support of citizens, courses, clubs, webinar programs, clubs for children and adults, lectures; popularization of topics at the request of communities; supervision and care); diagnostic; research; volunteer; sports and recreation; infrastructure; cultural and leisure; expert; development of the city's infrastructure. When building such interaction, it is important to take into account: regulatory and legal aspects of providing university infrastructure to urban communities and attracting teachers and students to implement educational programs for citizens of different ages; the financial side of interaction with urban communities; requests from urban communities; psychological and organizational aspects of interaction with urban communities; interaction with municipalities and representatives of district administrations, educational and other organizations working with the public and interested in the resources of the university.
Spiritual Security in the Conditions of Modern Cultural and Civilizational Development
Authors: Popov Evgeniy Aleksandrovich
Published: March 2023

The article reveals some possibilities for conceptualizing such a concept as spiritual security. At the same time, the author proceeds from the position that the political context of understanding spiritual security prevails in modern scientific discourse, but it clearly cannot be considered complete or sufficient. That is why the identification of spiritual security from the point of view of the cultural-philosophical approach provides the greatest heuristic potential for understanding spiritual security. Thus, the subject of the study is spiritual security within the boundaries of cultural and civilizational development. The emphasis is not on the genesis of the development of civilization and culture, but on their conjugacy in modern conditions. The main conclusions of this article are the following key provisions: 1) understanding the conjugacy of civilization and culture within the framework of the cultural-philosophical approach significantly increases the possibilities of conceptualizing these phenomena; 2) the study of spiritual security should be conducted through the prism of the correlation of this phenomenon with the levels of development of civilizations and cultures; 3) the absolute advantage of scientific understanding of spiritual security becomes a value-semantic perspective that allows overcoming the traditionally existing socio-political a vector in understanding spiritual security. The advantage of the proposed aspect is the orientation to the data of large-scale empirical studies devoted to the transformations of the value structures of human existence.
Demographic factor of integration of the territories of the deported peoples (on the example of the Volga Germans and Kalmyk ASSR)
Authors: Taktasheva Fliura Anvarovna
Published: March 2023

The article is devoted to the problem of economic and economic strengthening of territories disbanded as a result of ethnic deportations of the Kalmyk ASSR and the ASSR of Volga Germans in the 1940s. Based on the extensive historical literature on the problems of deportations, it is proved that the topic of integration of the territories of deported peoples has been little studied. The author shows the administrative and territorial changes that occurred in the Stalingrad region in connection with the annexation of the districts of the former republics. It is proved that the successful integration of the territories of the former republics into the economy of the Stalingrad region was based on the demographic factor. Based on the documents of the archives, the dynamics of the population, as well as the activities of regional authorities to replenish the human potential of these territories are analyzed. The novelty of the study is determined by the lack of a comprehensive study of the problems of integration of the territories of the Volga and Kalmykia German republics, most of whose population were deported, into the economic system of the Stalingrad region in the 1940s. For the first time, unpublished historical sources are introduced into scientific circulation, including statistical information and documents of the Stalingrad Regional Party Committee. As the main conclusion, it was established that by the beginning of the 1950s, the restoration of the pre-war population level did not occur, as a result of which the territories of the former republics remained economically inefficient.
