QUALIMETRY OF INNOVATIVE PRODUCTS WITH THE ADDITION OF THE SHRIMP PALAEMON ADSPERSUS
Authors: Sydorenko O. , Petrova O.
Published: December 2021

Crustaceans of the Azov–Black Sea basin, in particular, the shrimp Palaemon adspersus, are a type of raw material easily available in the domestic market, because the large volumes of its industrial production in the Azov–Black Sea basin make it inexpensive and abundant. That is why we have suggested innovative products with the addition of Palaemon adspersus meat: dumplings (pelmeni) and fish fingers. We selected the following main recipe components of these dumplings: Palaemon adspersus meat, Azov–Black Sea goby meat, unleavened dough, and those for fish fingers: Palaemon adspersus meat, Azov–Black Sea goby meat, egg powder. To enhance the taste and aroma, Svanetian salt was added to the minced meat in the model compositions of the products developed. To substantiate the rational content of the recipe components in the model compositions of products with Palaemon adspersus meat added, the method of qualimetric analysis of the sensory parameters was used. According to the results of qualimetric evaluation, it has been found that for dumplings, the best ratio of Palaemon adspersus meat, Azov–Black Sea goby meat, and unleavened dough is 1:2.7:3, and for fish fingers, the most practical ratio of Palaemon adspersus meat, Azov–Black Sea goby meat, and egg powder is 2.5:6.5:1. The obtained results of qualimetric analysis of the model compositions have been confirmed by mathematical calculations using multiple linear regression with initial determination of criterial factors of influence. According to the mathematical calculations performed, the highest value of the parameter (y1 = 0.93) has been obtained for the model composition of dumplings with Palaemon adspersus meat added with the ratio of the recipe components 1:2.7:3. For fish fingers, the highest value of the parameter (y4 = 0.8) has been determined for the model composition where the ratio of the recipe components was 2.5:6.5:1. These calculations confirm the objectivity, efficiency, and practicality of the chosen method of qualimetric analysis of the model compositions under study
EFFECT OF CHITOSAN PRETREATMENT ON THE QUALITY OF STRAWBERRIES DURING COLD STORAGE
Authors: Blahopoluchna A. , Liakhovska N.
Published: December 2021

The paper is focused on improving the technology of storing strawberries. It has been investigated how pretreatment of berries with aqueous solutions of low-molecular-weight chitosan of three concentrations (0.1%, 0.3%, 0.5%) affects the quality parameters of strawberries during refrigeration. The treated berries and the reference (untreated sample) were stored in 500 g perforated plastic containers at 0±2°C for 14 days. It has been found that strawberries treated with chitosan solutions had significantly smaller weight loss than the reference. At the end of storage, this parameter was 9.7% in the reference and 7.0–8.6% in the treated berries. It has been established that the respiration rate of the strawberries decreased sharply on the first day, which was caused by refrigerated storage, and continued to decline until the end of storage. Finally, this parameter attained the value 3.3 mg CO2/kg-1h-1in the reference and 2.2–3.0 mg CO2/kg-1h-1 in the treated berries. The hardness of the strawberries at the end of storage was 0.10–0.14 kg/cm2. The change in the lustre level of the berries has been observed. It has been established that on the 14th day of storage, the surface of the untreated berries was dull. The best characteristics have been observed for treatment at the chitosan concentration 0.5%. The effect of chitosan films on the sensory characteristics of berries has been investigated. It has been found that the pretreatment did not impair the taste of the berries. The results of the tasting evaluation indicate that the taste, aroma, and colour were better in the variants with the treatment concentrations 0.3 and 0.5%. However, as for the appearance and consistency, the experts preferred the berries treated at the concentration 0.5%. After two weeks’ storage, the strawberries have been found to be damaged by four fungal diseases. The infections found in the samples were Botrytis cinerea (grey mould), Rhizopus stolonifer (black mould), Whetzelinia sclerotiorum (white mould), and Penicillium spp. It has been established that pretreatment of strawberries with chitosan solutions reduces the development of phytopathogenic diseases. It has been shown that chitosan-based edible coatings have a positive effect on strawberries, increasing their shelf life and improving their quality. A conclusion has been drawn about the technology of application of chitosan solutions and about their concentrations.

Exploring the Diversity of Everyday Experiences through the Humans of the University of Wisconsin-Stout Facebook Assignment
Authors: Carter Genesea
Published: December 2021

In this personal essay and research article mash-up genre, I reflect on my Humans of the University of Wisconsin-Stout first-year composition Facebook assignment, which was developed to teach my predominately white students about the diversity of everyday experiences. I share with readers how my positionality, as a former evangelical Christian Republican who left Christianity and became a liberal progressive a few years before this assignment, and the context of my university, a predominately white, midwestern polytechnic university, shaped my assignment design. I include Humans of UW-Stout Facebook stories, corresponding student reflections and homework, and my own personal reflection on the curriculum to empower instructors to teach diversity-focused FYC assignments and to inspire instructors to reflect upon how their own political and religious beliefs shape their curriculum.
Writing While Black
Authors: Keeton Sarah
Published: December 2021

In this critical personal narrative Keeton explores how identity is negotiated at the site of their Black, queer body. They use autoethnography as a method to record their lived experiences in the context of the social, cultural, and political world. This writing explores their experiences with the education system and how their identities and experiences have influenced how they interact with the world, their perception of self, and their relationship with writing. Throughcritical reflection, Keeton describes how embodying an ethic of love and experiencing supportive role models within the education system allowed them to resist racist indoctrination and find their way to embodying healing and black self-love.
It Doesn't Have to Protest: A Review of Black or Right: Anti/Racist Campus Rhetorics
Authors: Denson Shenita
Published: December 2021

[To predominantly white institutions:] Whose responsibility is it to make our Black community feel like their lives matter here, and what are we purposefully and creatively doing about it [every day] to live up to it? Reflecting critically on my own intimate experiences as a Black doctoral student, college lecturer, and former student affairs professional in predominantly white spaces, I share an insightful review of Louis M. Maraj’s (2020) riveting new book, Black or Right: Anti/Racist Campus Rhetorics. Based on the title, I initially expected Black or Right to be some sort of a guidebook to help campuses learn how to refrain from using racist language in their marketing, programming, classrooms, and ways of interacting with campus constituents and community partners. I speculated that it would teach these same folx how to make Black faculty, staff, and students feel welcomed and equal instead of anxious and hyperaware. I thought about the white colleagues [and students] I could pass this text on to, with the accompanying note, “You might like this!,” which really means, “You need this.” Sigh. While Black or Right is not a guidebook on how to eliminate racist language on college campuses or an explicit outline for how to embrace the Black members on them, it is a beautiful piece of choreographed words that illustrates, examines, and disrupts how decolonized ways of writing, storytelling, and ways of being, teaching, and communicating on college campuses confronts, strategizes, calls out/in, and proclaims notions of Blackness in anti-Black spaces. I argue that this type of work is far more important than a Black person writing another book to teach white people how to talk to and treat us. Black or Right pays homage to and educates readers on the Black academy’s social justice pioneers, whose trailblazing paths and research encourage us to keep running in this race and reminds us we are dynamic. Courageously accepting the baton to complete the next leg, Maraj empowers and pushes us to run alongside him through his creative ability to discuss these topics through literary events, discussions, and assignments he has created in his own safe space, in his classroom. Brother Maraj, thank you for bringing your whole self, multiple identities, and diverse lived experiences to this text. In the spirit of your mother who allowed you to leave the islands to come to the US for greater opportunities - this book is a manifestation of her knowing your worth. Thank you for writing this fascinating piece that reminds us to never forget our worth, to demand our respect, and for educating and engaging all people in this necessary dialogue. Black is right. Black is right. Black is right. But Black folx are always protesting. Dear Brothers and Sisters, never forget: We always mattered.

It is essential to develop entrepreneurship in Russia, both to promote economic growth of the country and its regions, and to create jobs and opportunities for highly qualified personnel. At the same time, institutions and spatial concentration of business are known to affect enterprise activity. The aim of our research is to estimate the role of institutional factors and spatial concentration in entrepreneurial activity in Russia's regions. We use panel data for 80 Russian regions covering the period from 2008 to 2018 and apply the system generalized method of moments. Our main contribution to the research on Russian regions is that in addition to institutional factors we estimate spatial effects, while performing a comprehensive analysis of entrepreneurial activity, i.e. considering small, medium, and large enterprises. The results of the empirical analysis show that the impact of institutional factors on entrepreneurship in Russia is varied. The number of economic crimes in the region negatively and significantly affects medium and large business. Corruption is found to be significant only for large business, while the level of the banking system and the risk index positively affect firms of all sizes. We also reveal a positive impact of entrepreneurship in the neighboring regions on the entrepreneurial activity in the region under consideration and confirm that spatial effects decline with distance. We conclude that institutional and spatial factors deserve attention while elaborating and implementing economic policy measures aimed at development of entrepreneurial activity. The heterogeneity of the development of entrepreneurship in the regions indicates the need for a differentiated policy in the field of entrepreneurship. An effective policy for one region may not be suitable for other regions, so government support should differ depending on the situation and the recipient. The results of our research can be useful for designing regional economic policy.

Published: December 2021

La velocidad con la que se genera información y el fácil acceso que existe hoy en día a muchas fuentes de información, precipita la obsolescencia del conocimiento adquirido en detrimento del nuevo. Muchos sistemas educativos no han sido ajenos a esta realidad y han adaptado las metodologías pedagógicas para incluir la educación por competencias. Estas son el conjunto de habilidades que engloban conocimientos conceptuales, actitudinales y procedimentales que permiten enfrentarse a los retos diarios con efectividad. Estas competencias evolucionan y se van añadiendo nuevas teniendo en cuenta las necesidades de cada momento, es en este sentido que cobra fuerza la idea de varios países de incluir el Pensamiento Computacional como competencia ya que esta comprende herramientas muy importantes para el aprendizaje de la ciencia, tecnología, ingeniería y matemáticas, que utiliza la programación como medio. Con el objetivo de promover estas competencias, Plan Ceibal en 2017 comenzó un programa piloto con 33 escuelas y en 2021 ya participaban en el programa (voluntario) casi el 54% de escuelas públicas urbanas. En este sentido, se considera importante evaluar el desempeño de los estudiantes en Pensamiento Computacional, y por falta de instrumentos de medida estandarizados se empezó el proceso de creación y validación de un instrumento de medida estandarizado en formato de videojuego. Este trabajo pretende presentar los avances en la generación del videojuego. De este objetivo general se desprenden los siguientes objetivos específicos:1. Operacionalizar los componentes que conforman el Pensamiento computacional. 2. Decidir qué componentes resultan medibles teniendo en cuenta el formato de la evaluación. 3. Dar algún ejemplo de ítem interactivo. En la actualidad se está programando el instrumento y se realizarán estudios de validez y fiabilidad.
Uso de internet para conocer parejas sexuales y/o románticas: preferencias en función del género y de tener o no pareja estable
Authors: Cervigón-Carrasco Verónica , Elipe-Miravet Marcel , Castro-Calvo Jesús , Giménez-García Cristina , Ballester-Arnal Rafael
Published: December 2021

Una de las principales motivaciones para consumir cibersexo es conocer a otras personas con fines románticas y/o sexuales. Parece que el género podría ser importante a la hora de modular la realización de este tipo de Actividad Sexual Online (ASO); sin embargo, los datos son escasos y no siempre apuntan a la misma dirección. Así mismo, tampoco se ha estudiado ampliamente el impacto que puede tener el hecho de tener una relación estable sobre el consumo de este tipo de ASO. Por ello, el objetivo de este trabajo es analizar la influencia del género y tener o no pareja estable sobre el uso y la selección de ASOs que impliquen la interacción sexual y/o romántica con otros usuarios online. Para ello, 120 personas de entre 18-48 años (59.17% mujeres, 40.83% hombres; 56.65% sin pareja estable, 43.35% con pareja estable) cumplimentaron un cuestionario sobre conductas y prácticas sexuales online. El flirteo e insinuaciones a terceros es la ASO interactiva más común en hombres (55.1%) y mujeres (45.1%). Los hombres tienden a preferir aquellas ASO interactivas que buscan establecer contacto sexual offline, mientras que las mujeres presentan preferencia por el cibersexo online. Sin embargo, las diferencias de género solo son estadísticamente significativas para la búsqueda de pareja sexual online (χ2= 3.870; p=.049). El consumo de cibersexo interactivo es muy común en personas con una relación estable (89.5%-92.9%), de forma que no se aprecian diferencias estadísticamente significativas respecto a los solteros para ninguna ASO. Este trabajo nos ha permitido demostrar que el género se constituye como un claro factor modulador en el uso y la selección de ASOs para conocer a gente con fines sexuales y/o románticos. No obstante, parece que el hecho de tener o no pareja estable no es un factor explicativo de este uso.
Plan de acción tutorial para prevenir el acoso escolar transfóbico en la adolescencia
Authors: Sánchez Sánchez Tara , Etopa Bitata María del Pilar
Published: December 2021

Diversas investigaciones sobre el acoso escolar transfóbico en España corroboran que el 46,2% del acoso que sufren las personas trans* ocurre en los centros educativos, convirtiéndose en el segundo contexto donde más acoso experimenta este colectivo (Devís-Devís et al., 2017). Por tanto, a pesar de la implementación en el año 2014 de la Ley de Igualdad LGTBI por parte de ciertas comunidades autónomas, hoy en día, aparece en las aulas un 58% de casos de acoso transfóbico en todas las etapas educativas, observándose un 37% de casos en la etapa de secundaria (FELGTB, 2019a). En cuanto a la tipología de las agresiones, pese a la variabilidad, las investigaciones hacen referencia a las agresiones verbales como las más frecuentes (Devís-Devís et al., 2017; FELGTB, 2019a; FELGTB, 2019b; Martín et al., 2019), pero las y los menores trans* también sufren agresiones físicas, aislamiento social, ciberacoso y acoso sexual (FELGTB, 2019a). Por ello, cuando el acoso transfóbico se prolonga en el tiempo afecta a la estabilidad psicológica de la víctima, elevando el riesgo de suicidio que, según los estudios, afecta al 20% de los chicos y las chicas trans*. A este respecto, se destaca la importancia de afrontar esta realidad en las instituciones educativas, puesto que, tanto los acontecimientos sociales que vivimos día a día como las cifras generales de diversas investigaciones estatales muestran que los casos de transfobia han crecido exponencialmente, sucediendo más de la mitad de ellos en los centros educativos. Dada esta alarmante situación, surge la necesidad de elaborar un programa de intervención para, a través del Plan de Acción Tutorial, prevenir el acoso escolar hacia el alumnado trans* en la etapa de Educación Secundaria; formando a jóvenes más concienciados, empáticos y asertivos que favorezcan la creación de entornos seguros e inclusivos, impulsando el cambio social.
Consumo excesivo de alcohol ¿existen diferencias de género?
Authors: Elipe Miravet Marcel , Cervigón Carrasco Verónica , Fernández García Olga , Estruch Verónica , Ballester Arnal Rafael
Published: December 2021

El consumo de alcohol es una práctica muy extendida en nuestra sociedad, pese a sus nocivas consecuencias (intoxicaciones etílicas, accidentes de tráfico, reyertas, ITS, etc.). Aunque sus efectos afectan a toda la población, con independencia del género o la edad, las estrategias preventivas no siempre tienen en cuenta dicha diversidad; aspecto que, seguramente, reduce su eficacia. Dada la necesidad de contar con un perfil más concreto de quienes consumen alcohol de manera más riesgosa, el objetivo de este trabajo es conocer si existen diferencias, según el género y la edad, en la vivencia de algunas consecuencias derivadas del consumo de alcohol. Para ello, 60 participantes (35 mujeres y 25 hombres), con edades comprendidas entre los 22 y los 64 años, respondieron una encuesta sobre el consumo de sustancias. Los resultados muestran que el 100% de hombres y el 97% de mujeres han consumido alcohol. Los primeros son los que más han vomitado por la ingesta de alcohol (52.8%; 2=4.91; p=.027), más veces han ido en estado de embriaguez al trabajo (87.5%; 2=7.72; p=.005), y más veces han conducido borrachos (66.7%; 2=7.88; p=.005). Por otro lado, la única diferencia que existe en función de la edad se centra en la experiencia de haber vomitado, siendo mayor entre las personas que tienen más años. A la vista de los resultados, preocupa la cantidad de consecuencias de riesgo que están asociadas a un consumo excesivo de alcohol, especialmente para los hombres; destacando igualmente el indicador de vomitar según la edad. Es por eso que, a la hora de realizar intervenciones de prevención, debería tenerse en cuenta la perspectiva de género, ampliando de igual forma los esfuerzos a todas las edades, y no solamente centrar las campañas e intervenciones hacia los más jóvenes.
Na teia da ficção: a complexa narrativa da síndrome de Munchausen por procuração
Authors: Lopes Elisabete , Caçador Anastácio Zélia
Published: December 2021

A Síndrome de Munchausen por Procuração, também designada como Transtorno Factício Imposto a Outro, é definida como uma perturbação significativa, complexa e, por conseguinte, de difícil controlo e diagnóstico. A sua complexidade deve-se ao facto de ser considerada como tipologia de abuso infantil em que o agressor, geralmente a mãe, induz ou simula, deliberadamente, sinais e/ou sintomas de doença no filho/a com intuito de obter atenção para si. É representada por uma relação triangular que envolve, mãe-agressor, filho/a-vítima e médicoprofissional de saúde, sendo este último utilizado pelo/a perpetrador/a do abuso para satisfação da sua necessidade intrínseca e, por consequência, na perpetuação do abuso. O presente artigo propõe uma revisão narrativa da literatura sobre a Síndrome de Munchausen por Procuração tentando enquadrá-la à luz da designação do abuso infantil, ao mesmo tempo que procura alertar para a necessidade da sua identificação precoce pelos profissionais de saúde, visto que este comportamento pode conduzir à morte da criança.

As you know, when conducting small - and medium - scale works (regional survey or search), one of the main sources of obtaining information about large structures is the decoding of aerial and space images. However, only pronounced large structural elements are well identified, while the identification of small or specific elements is very difficult. It is in such cases that a digital surface model can serve as a source of additional information.

Influence of public agricultural extension on technology adoption by small-scale farmers in Zimbabwe
Authors: Masere TP , Worth S
Published: December 2021

This paper presents the findings of challenges facing Zimbabwe’s extension services and how these have affected the adoption of technologies they render to small-scale farmers. This study uses a critical review of relevant literature on Zimbabwe’s primary public extension agency (AGRITEX). Additionally, 21 key informant interviews (KIIs) were conducted to corroborate data collected in secondary research on extension approaches currently in use, the key factors affecting technology adoption, and the technology adoption process of small-scale farmers. The study found AGRITEX’s major challenges to be poor funding, poor remuneration and incentives for extension personnel, lack of in-service training, lack of appropriate technology, as well as poor operational resources like transport to reach all farmers. Consequently, services offered to small-scale farmers were compromised, which led to poor adoption of recommended technologies. Furthermore, the study determined that key factors influencing technology adoption are related to the farmers’ circumstances, the operating environment, and the attributes of technology itself. As a lasting solution to poor technology adoption, an adaptive extension system that promotes building the capacity of extension workers and researchers, as well as embracing farmers and their indigenous knowledge, is proposed.
Socio-economic factors affecting home gardens as a livelihood strategy in rural areas of the Eastern Cape province, South Africa
Authors: Mdiya L , Mdoda L
Published: December 2021

Home gardens have been identified as one of the possible ways of producing food and offer great solutions to some of the issues surrounding poverty alleviation and improving food security in rural areas. However, home gardens' potential as a living strategy has not been recognized and affected by many factors. Therefore, the study examines socio-economic factors influencing home gardens as a living strategy in rural areas of the Eastern Cape Province. The study was conducted in the Eastern Cape Province rural areas, where data was collected from 200 households using snowball sampling. The study made use of descriptive and logit regression models for analysis. The study results reveal that female households actively participated in home gardens with an average of 46 years. Households were landowners with an average farm size of 3 Ha and owning farm assets. Home gardens contributed immensely to households by providing food for home consumption and generating income from crops and vegetables. The study concludes that Socio-economic factors were the factors influencing home gardens as the living strategy in rural areas. Therefore, the study recommends the provision of external personnel in rural areas to assist home gardeners in improving their productivity.
South African government palliative funds for agriculture amid Covid-19: Challenges of implementation and suggestions for improvements
Authors: Popoola OO , Yusuf SFG
Published: December 2021

The novel Corona virus pandemic has been extremely overwhelming at all levels causing massive economic setbacks for many countries including South Africa. The country witnessed an unprecedented scaling-down of its national economic activities, which called for an emergency response from the government. Several Covid-19 relief schemes were instituted by the government to ensure that farms of all sizes would survive. A support fund of R1.2 billion was allocated to the agriculture and food sector through the Department of Agriculture, Land Reform and Rural Development (DALRRD). The fund was primarily meant to assist financially distressed small-scale farmers to ensure continued production and food security for the country. This study collated the conditions for financial Covid-19 stimulus support required from smallholders and analysed several factors that prevented some members of this vulnerable group from benefitting from the relief funds. These factors include complexities associated with satisfactorily categorizing smallholder producers, productivity, marketing and policy challenges, glitches in formalising smallholder producer operations, the farm-business record keeping pitfall, and the exclusion of subsistent producers. The paper suggests some possible corrective measures that could allow for more inclusive support to these categories of farmers; some of which includes a simple but robust financial traceability system for the farmers, and a need to continue to push for the completion of national registration process of smallholder producers.

The purpose of the study was to characterize irrigated smallholder agricultural enterprises (ISAEs) in selected areas of Vhembe District, Limpopo Province. The characterization focused on the geophysical environment and on participants in ISAEs.  Precipitation was at most 460mmpa for villages along Madimbo Corridor and 701-1380mmpa for those along Mutale Valley, and temperatures were 38.1℃-44.0℃ (Madimbo) and 30.0℃-40.0℃ (Mutale). Groundwater supplemented surface water and was utilized more at Madimbo Corridor compared to Mutale Valley. The study area was characterized as semi-arid to sub-humid, hence technologies for efficient irrigation should be promoted. Participants in ISAEs were female (94.9%), and adult (52.72%) with low education levels (67.7% ≤ secondary education). The majority (88.65%) were not formally employed (54.61% self-employed, 34.04% full-time farmers). Participants experienced some level of poverty, 68.03 percent received low household incomes (R1001-R5000/month), 77 percent received social grants. Interestingly, the majority (65.31%) stayed in multiple-roomed houses, had cement brick walls, and corrugated iron roofs (54.42%), and all had electricity, a stove, and a fridge. Also, majority-owned radio (96.67%), DSTV (87.45%), vehicles (65.56%), and cellphones. Participants mostly provided adequate food supply (91.84%) with three meals/day (79.38%) except during hard times where 49.56 percent provided fewer meals mostly due to delayed readiness of farm produce. Strategies to empower ISAE participants to be more effective should consider their gender, age, education, and economic status estimated by income, asset ownership, and food security.

The consequences of climate change threaten existing agriculture systems across Zimbabwe. The researchers examined the possibility and potential for developing a smallholder farmer driven macadamia nuts value chain. Using the case of Chipinge district, Manicaland province, Zimbabwe, the study evaluated the potential of macadamia nut value chain functions as a climate change resilience strategy in Zimbabwe. Challenges faced by actors and positive developments made in incorporating smallholders into the macadamia nuts production sector were explored. The role of local markets and producers in the international trade in macadamia nuts were also examined, using a modified stakeholder analysis framework. Triangulation, a mixed methodology, was used to adequately capture the various quantitative and qualitative dimensions along the macadamia nuts value chain pillars. A sample of 220 farming units including Estates, A1 and A2 farmers was proportionately selected for the study. Primary data were collected from Key Informants through interviews and personal communications. Secondary data were collected from Agritex officers, buyers, and the Macadamia Association of Zimbabwe farmers’ records.  The production-marketing interface for macadamia nuts is weakly coordinated in the study area as shown by the rudimentary production systems especially for the A1 and A2 farmers. Results show that the major missing links are the limited application of extension driven production enhancers and the limited visibility of farmers in more rewarding export markets. Production scales have, however, been increasing with more farmers allocating land towards the macadamia nuts trees. Decentralization of macadamia nuts markets and localized value addition needs to be done to realign domestic and export market prices.
BIO-LAW AS A NEW GENERATION OF LAW

The development of national and international biotechnology law in the context of new constitutional priorities, threats and challenges to life, public health and safety, is one of the current and yet under-researched topics in the scientific legal literature. Unfortunately, pro-gress in the life sciences is proceeding faster than the legal thinking that should accompany them. Breakthroughs in biology and medicine dictate the corresponding development of law, which today unfortunately lags chronically behind, resulting in gaps and contradictions between existing legal norms. As contemporary researchers have noted, and as is also evident in judicial practice, the issues of regulating the objects of bio-law - the body, life, procreation, self-identification, and ecology - mirror the contradictions of our society. The need to legally regulate the application of biotechnology has led to the formation of bioclaw as a new, integrated set of laws and, in the long term, as a branch of law of a new generation. As a response to the rapid introduction of advances in biotechnology into human life, we believe that bio-law must take into account the benefits and challenges associated with the impact of new technologies on the human body that may fundamentally alter the human condition as a physical individual. In this case, ethical issues, i. e. the requirements of bioethics, lead to a reflection on the content of bioethics in contemporary democracies and legal states. In particular, the introduction of technologies associated with gene editing, cloning, surrogacy, transplantation medicine, sex reassignment surgeries and other interventions into human nature, the consequences of which are not fully understood and threaten the physical and mental health of individuals, can cause irreparable harm to the spiritual, social, moral and ethical foundations of individuals, families, society, states and humanity as a whole. In our opinion, in the next few decades, bio-law will emerge as a global, integrated branch of law that simultaneously incorporates the norms of international law and national law. The main purpose of bio-law as a new branch of law is to counteract the global threat to humanity which consists in the emergence of a trend toward mass, large-scale changes to human nature and its unique natural qualities through the use of biotechnological advances. Therefore, the object of regulation and, accordingly, protection by this branch of law is not only the individual, his or her physical and spiritual health, but humanity as a whole, current and future generations. The uniqueness of bio-law as a new branch of law also lies in the fact that the individual, humanity, present and future generations are both the objects and subjects of law. The integrated nature of bioprinciples is manifested in the close connection of public and private interests with the obvious predominance of the public significance of their legal norms.

Introduction. The transition to parenthood can be a source of stress for fathers and, in some cases, it can be accompanied by emotional distress. This aspect has been neglected in Mexican research. Objective. To estimate the prevalence of emotional distress and the sociodemographic factors associated with it in Mexican fathers. Method. Cross-sectional study. A subsample of 997 fathers, over 18 years of age, was taken from the data of a national survey, whose partners were pregnant or had given birth in the last six months. The Kessler Emotional Distress Scale (K6) was used. Results. About 25% of the fathers experienced moderate emotional distress during their partner's pregnancy and 29.5% during the postpartum period; 1.0% and 1.9% showed serious emotional distress in those periods, respectively. Being between 18 and 29 years old (PR = .10; CI [.01, .79]), having lower educational attainment (PR = 5.59; CI [1.19, 26.21]), and going through postpartum (PR = 4.11; CI [1.00, 16.78]) were at higher risks for severe emotional distress; having one or two children (PR = .16; CI [.05, .55]) or more than three (PR = .08; CI [.01, .44]) was a higher risk than being a first-time father. Discussion and conclusion. It is necessary to continue studying paternal perinatal mental health due to the impact it has on the mother and the infant, and to design tailored interventions. Parental emotional distress needs to be better understood considering recent changes in the paternal role in developing countries.
RELATIONSHIP BETWEEN STATE AND PUBLIC CONTROL OF THE ELECTION PROCESS IN UKRAINE

During the years of independence, Ukraine has undergone certain processes that have led tochanges in the relationship between government and society. These changes were not alwayspositive. State power had a high level of authority in the eyes of the Ukrainian people. The majorityof the population does not believe in the objectivity of the results of the people’s will, which, infact, stimulates interest and shows the importance of public control over the election process.The purpose of the article – is to study the correlation of the state and public control over thesuffrage of Ukraine and its influence on the formation and development of civil society.The methodological basis of the study were general scientific and special legal methods ofcognition. Among the general scientific methods used is the method of philosophical dialectics,which is revealed through the methods of analysis and synthesis, ascent from simple to complex,from abstract to concrete, modeling, abstraction, idealization and formalization.Despite the expansion of opportunities to influence the future of the country through the free willof the people, the importance and effectiveness of public control faces a number of obstacles. Forexample, the presence of underdeveloped civil society, the lack of a prescribed mechanism for publiccontrol, political indifference of citizens, the negative impact of bureaucratic manifestations – allthis and many other factors together have a negative impact on the development of civil societyand effective control for the election process. But a rather significant shortcoming in the way ofits development is the lack of scientific research on this issue.As a result of the research, it was found that through election procedures it is possible to bestbalance and reconcile the interests of political elites, social classes, groups of the whole society,to bring the government closer to the needs of the people. The public sector plays a positive role in the processes of stabilization and harmonization of relations in society and the electoral processin particular. Public control as a social phenomenon is impossible without the formation of afavorable environment for its full and effective functioning, ie without a developed civil society.The article concludes that election control can be effective only when it is carried out by anindependent third party, in our case – civil society in relation to public authorities and localgovernments, which are directly involved in ensuring the preparation and conduct of the electionprocess. Many years of international and national experience clearly show that the lack or lowlevel of public control over the electoral process and excessive state control ultimately lead tousurpation of power and falsification of election results.
