Authors: Adedoja Dorcas , Kuhns Lisa M , Radix Asa , Garofalo Robert , Brin Maeve , Schnall Rebecca 
Published: May 2024

Background
Transgender men and transmasculine youth are at high risk for acquiring HIV. Growing research on transgender men demonstrates increased HIV risk and burden compared with the general US population. Despite biomedical advancements in HIV prevention, there remains a dearth of evidence-based, sexual health HIV prevention interventions for young transgender men. MyPEEPS (Male Youth Pursuing Empowerment, Education, and Prevention around Sexuality) Mobile is a web-based app that builds on extensive formative community–informed work to develop an evidence-based HIV prevention intervention. Our study team developed and tested the MyPEEPS Mobile intervention for 13- to 18-year-old cisgender young men in a national randomized controlled trial, which demonstrated efficacy to reduce sexual risk in the short term—at 3-month follow-up. Trans men and transmasculine youth resonated with basic HIV educational information and sexual scenarios of the original MyPEEPS app for cisgender men, but recognized the app's lack of transmasculine specificity.

Objective
The purpose of this study is to detail the user-centered design methods to adapt, improve the user interface, and enhance the usability of the MyPEEPS Mobile app for young transgender men and transmasculine youth.

Methods
The MyPEEPS Mobile app for young transgender men was adapted through a user-centered design approach, which included an iterative review of the adapted prototype by expert advisors and a youth advisory board. The app was then evaluated through a rigorous usability evaluation.

Results
MyPEEPS Mobile is among the first mobile health interventions developed to meet the specific needs of young transgender men and transmasculine youth to reduce HIV risk behaviors. While many of the activities in the original MyPEEPS Mobile were rigorously developed and tested, there was a need to adapt our intervention to meet the specific needs and risk factors among young transgender men and transmasculine youth. The findings from this study describe the adaptation of these activities through feedback from a youth advisory board and expert advisors. Following adaptation of the content, the app underwent a rigorous usability assessment through an evaluation with experts in human-computer interaction (n=5) and targeted end users (n=20).

Conclusions
Usability and adaptation findings demonstrate that the MyPEEPS Mobile app is highly usable and perceived as potentially useful for targeting HIV risk behaviors in young transgender men and transmasculine youth.

Published: May 2024

Introduction. Chemoresistance is a multifactorial phenomenon implicated in all failed therapies and accounts for 90% of all cancer deaths and 30% of relapses. Objective. To understand the genetic mechanisms by which cancer cells acquire resistance to chemo drugs. Methodology. A non-systematic review study was carried out, in which genes and proteins involved in chemoresistance were searched using the terms “Cancer Drug resis-tance [Title/Abstract]”. From the articles obtained, highly involved genes, emerging genes, and proteins related to resistance were recognized. To obtain more specific information about genes, their interactions, and proteins associated with metabolism, the tools “The Human Protein Atlas”, “STRING CONSORTIUM 2022,” and The Small Molecule Pa- thway Database were used for their review. Results. From this review it was found that there are genes highly related to resistance such as: ABCA3, ABCB1, ABCB2, ABCC1, ABCC2, ABCG2, CYP2D6, CYP3A4, GSTA1. Recently recognised genes such as: FOXO3,FOXM1, Skp2, Snail, Twist1, ZEB1 and SLCO1B3. Conclusions. It is necessary to taking account new approaches related to cancer treatments considering chemoresistence and the genes related to the resistence.
CEO Incentives for Risk-Taking and Compensation Duration
Authors: Kubick Thomas R. , Robinson John R. , Starks Laura T. 
Published: May 2024

ABSTRACT
When determining new equity grants, corporate boards face a tradeoff between the CEO’s incentives generated from the grant’s duration versus those arising from the convexity of the embedded equity risk. We hypothesize and find that boards lengthen the horizon of new compensation grants in the presence of greater pre-existing compensation sensitivity to stock return volatility (vega). In addition, consistent with our hypothesis, we find stronger results in the presence of greater left-tail risk. Further, employing two exogenous shocks to left-tail risk, we provide evidence consistent with our hypothesis that grant horizons are related to risk incentives. Our analysis of the interaction of these two incentive mechanisms provides new insights on compensation contracting.

Testate amoebae of the natural monument bog “Klyukvennoye-2” (Usman pine forest, Voronezh Oblast, Russia)
Authors: Загумённая О.Н. 
Published: May 2024

В работе впервые рассматриваются результаты изучения видового состава сооб- ществ раковинных амеб из разнотипных микробиотопов, отличающихся по степени обводнен- ности и составу субстрата переходного болота Клюквенное-2 (ООПТ) Усманского бора. Выяв- лено 72 вида раковинных амеб. Наиболее богатыми по числу видов и количественному обилию были мезофильные сообщества раковинных амеб, населяющие промежуточные местообитания между моховыми и водными микробиотопами. Сообщество раковинных амеб, населяющих су- хие сфагновые кочки, отличалось самыми низкими показателями. Среди всех выявленных видов Arcella gibbosa имела максимальное количественное обилие.
This paper was the first to present the results of investigations of species composition of testate amoebae from different microbiotopes with regard to watering and a substrate type of the protected natural area “ bog Klyukvennoye-2” of Usman Pine Forest. A total of 72 species of testate amoebae were identified. Mesophilic communities of testate amoebae dwelling in the intermediate habitats between moss and aquatic microbiotopes were the richest in terms of species number and abundance. These indicators for the testate amoebae community inhabiting dry sphagnum tussocks turned out to be the least. Arcella gibbosa had the highest abundance among all identified species.

Установлено влияние гидрологических и метеорологических факторов (температу- ры воды, атмосферных осадков, притока воды в водохранилище, сбросов в нижний бьеф, уров- ня и объема водохранилища, интенсивности внешнего водообмена) на химический состав воды (содержание растворенного кислорода, взвешенных веществ, нитратов, нитритов, соединений, содержащих аммонийный азот, сульфатов, хлоридов, фосфатов, ряда органических веществ и тяжелых металлов) Новосибирского водохранилища в средние по водности годы. Рассмотрены периоды весеннего наполнения водохранилища и летней стабилизации уровня воды на отметке нормального подпорного уровня как периоды формирования качества воды водохранилища и наиболее активного развития биоты.
The influence of hydrological and meteorological factors (water temperature, precipitation, intensity of external water exchange, water inflow into the reservoir, discharge to the downstream, water level, reservoir volume) on the chemical composition of water (content of dissolved oxygen, suspended solids, nitrates, nitrites, compounds containing ammonium nitrogen, sulfates, chlorides, phosphates, a number of organic substances and heavy metals) of Novosibirsk Reservoir in the mean-water years was analyzed. The period of reservoir filling in spring and the period of water level standing at the normal maximum operating level in summer were investigated as the times most important for water quality and biota development in the reservoir.

Поиск растений-концентраторов тяжелых металлов (ТМ) имеет значение с диагно- стической и ремедиационной сторон. В ходе работы были измерены валовые содержания Cd, Zn, Ni, Cu, Pb в листьях тополя канадского Populus canadensis Moench и ясеня американского Fraxinus americana L. – деревьев, часто используемых в озеленении населенных мест. Методом атомно-абсорбционой спектроскопии исследованы воздушно-сухие биопробы листьев деревьев, собранные в течение одного вегетационного сезона на 5 участках, расположенных на террито- рии г. Кирова (Россия, Кировская область). Показано, что в листьях тополя в большей степени аккумулировался цинк, максимальное накопление которого установлено в промышленных зонах города. Листья ясеня в большей степени накапливали медь и свинец, содержание которых было высоким на всех участках.
The search for heavy metal concentrator plants is important in terms of diagnostics and remediation. In the course of the work, the gross contents of Cd, Zn, Ni, Cu, Pb were measured in the leaves of poplar Populus Canadensis Moench and ash Fraxinus Americana L. These trees are often used in the landscaping of populated areas. Air-dry samples of tree leaves collected during one growing season at 5 sites located on the territory of Kirov (Russia, Kirov oblast) were studied by atomic absorption spectroscopy. Zinc was accumulated to a greater extent in poplar leaves. Maximum accumulation of zinc was noted in the industrial areas of the city. Ash leaves largely accumulated copper and lead, the content of which was high throughout.

Впервые изучены эколого-физиологические и видовые особенности системы лей- коцитов крови двух видов цикломорфных грызунов – рыжей полевки Myodes glareolus Schreber, 1780 и малой лесной мыши Apodemus uralensis Pallas, 1811 на сопредельных территориях Коло- гривского и Костромского районов Костромской области. Установлено, что лейкоформулы иссле- дуемых грызунов видоспецифичны и значимо отличаются у особей, обитающих на территории заповедника «Кологривский лес» и на территории Костромского лесничества. Многофакторный дисперсионный анализ выявил существенное влияние на лейкоформулу всех изученных фак- торов: «локация отлова», «видовая принадлежность», «пол», «стадия популяционного цикла» и «год исследования». Относительно высокая степень девиации индекса селезенки у исследуемых видов свидетельствует о неоднородности популяций по данному признаку. При этом достоверной сопряженности риска развития спленомегалии у мышевидных грызунов с особенностями их ре- продуктивной стратегии и восприимчивости к инвазиям не обнаружено.
The ecological, physiological and species-specific characteristics of the leukocyte profile of two species of cyclomorphic rodents, the bank vole Myodes glareolus (Schreber, 1780) and the pygmy wood mouse Apodemus uralensis (Pallas, 1811), were studied for the first time in the adjacent territories of the Kologriv and Kostroma districts of the Kostroma Oblast. It was established that the leukocyte profiles of the studied rodents are different in different species and vary significantly among individuals inhabiting the Kologrivsky Forest Reserve and the Kostroma Forestry. Multivariate analysis of variance showed that the white blood cell differential parameters largely correlate with the following factors: “location of capture,” “taxonomic species,” “gender,” “stage of the population cycle,” and “year of study.” The relatively high degree of deviation of the splenic index in the studied species indicates the heterogeneity of populations for this trait. At the same time, no reliable association was found between the risk of developing splenomegaly in mouse-like rodents, and the characteristics of their reproductive strategy and susceptibility to invasions.

El objetivo de esta investigación fue identificar los factores principales considerados en la administración del hogar para luego señalar su relación con el nivel educativo, la edad y el género. Para ello, se realizó un análisis directo de la forma en cómo se ha presentado el ingreso y gasto a nivel nacional, a partir de la Encuesta Nacional de Ingresos y Gastos de los Hogares (ENIGH) 2022, con un total de 37 millones de viviendas analizadas. Como complemento se efectuó una encuesta con una muestra de 212 casos para identificar y contrastar la forma en que algunas familias administran sus hogares (caso de estudio) a través de la prueba de ji al cuadrado, utilizando el software IBM SPSS Statistics 23. Los resultados señalaron que la principal fuente de ingreso de los hogares fue el trabajo, que sumó el 65.7 % del ingreso total, posteriormente las transferencias y la estimación del alquiler de la vivienda, que representaron el 17.2 y 11.8 %, respectivamente. El gasto corriente por grandes rubros fue para alimentos, bebidas y tabaco, posteriormente para transporte y en tercera posición para la educación. Los hogares de la CDMX, Baja California y Querétaro presentaron el mayor gasto promedio mensual. Igualmente, los resultados del caso de estudio mostraron que únicamente el 56 % reconocen que administran sus hogares y de ellos 58 % son mujeres. Finalmente se acepta la H0, ya que el resultado de la prueba fue mayor que 0.05, es decir, no existe una correlación directa entre la administración del hogar con la edad, el género ni el nivel de educativo.

Authors: Restrepo Betancur Luis Fernando 
Published: May 2024

El sector agrícola desempeña un rol muy importante en la economía mundial, su papel es protagónico tanto en la generación de empleo como en la contribución de los ingresos y la renta de las naciones. Las mujeres que se ocupan de las labores del campo tienen poca participación en la toma de decisiones y en el liderazgo de los diferentes procesos relacionados con el agro. El objetivo del presente estudio consiste en describir estadísticamente la participación femenina en el sector agropecuario en Sudamérica en las últimas dos décadas. El estudio es de tipo descriptivo comparativo de carácter longitudinal. Ecuador, Chile y Perú son las naciones con mayor tenencia de la tierra por parte del sexo femenino. Se detectó diferencia estadística entre las diferentes naciones de Sudamérica. Es necesario fomentar programas orientados a reconocer y a apoyar a las mujeres campesinas como socias productoras con capacidad de decidir y con autonomía.

Authors: Melnikova Elena B. , Melnikov Anatolii V. 
Published: May 2024

Abstract
A study was conducted on the changes in sea surface temperature (SST) on the southwestern shelf of the Crimea between 2000 and 2020. The equations of trends in the change of SST were found. It is shown that the following three periods can be distinguished according to the nature of changes in the average annual sea temperature: 2000 - 2007, 2008-2013 and 2014 - 2020. The influence of changes in the average annual SST on the development of pelagic fish of the cold-water complex was considered (using the example of the Black Sea sprat). Changes in the main parameters of the populations and their relationship with the change in the average annual SST were determined. It was found that the increase in sea temperature negatively affected the development of the sprat population, and the average age of the population decreased by 1.3 times. In general, the population was rejuvenated, and the average size and weight of individuals decreased.
Structures of breeding bird communities in wooded and densely built-up areas in a city centre in SW Poland
Authors: Kopij Grzegorz 
Published: May 2024

Abstract
Breeding bird community in the city centre of Brzeg was quantified by means of the simplified version of the territory mapping method. The centre consists two habitats: densely built-up area (c. 40 ha) and wooded belt (c. 26 ha) around the built-up area. In 2022, 46 breeding bird species were recorded in the city centre; 25 species in the built-up area and 36 in the wooded area. The group of dominants in Brzeg city centre was composed of Apus apus, Columba livia, Sturnus vulgaris, Streptopelia decaocto, and Passer domesticus. They comprised together 59.1% of all breeding pairs of all species recorded. The group of subdominant was composed of five species Columba palumbus, Turdus merula, Cyanistes caeruleus, Sylvia atricapilla, Phylloscopus collybita (together 15.9% of all breeding pairs). In wooded area the following species were dominants: Stunus vularis, Columba palumbus, Turdus merula, Cyanistes caeurlea and Sylvia atricapilla (together 44.9%); while in built-up area: Apus apus, Columba palumbus, Streptopelia decaocto and Passer domesticus. Two species: Apus apus and Columba livia comprised 2/3 of all breeding pairs in the built-up area. Insectivores and granivores were the most numerous feeding guilds in the built-up area (58.3% and 39.3% respectively), whereas in the wooded area, the insectivores were much more numerous (75.0%) than the granivores (20.1%). In built up areas, most birds nested on buildings (79.8%), much less on trees or shrubs (15.6%), in tree holes (4.0%) and in herbaceous vegetation (0.2%). In the wooded area, most birds nested on trees/shrubs (52.8%) and in tree holes (37.3%).
Investigation of Phase Separation and Morphology of Organic-Inorganic Interpenetrating Polymer Networks
Authors: Tsebriienko T. , Popov A. 
Published: May 2024

Abstract
The paper investigates the process of phase separation and morphology of organic-inorganic interpenetrating polymer networks (OI IPNs) based on the cross-linked polyurethane (PU), poly(hydroxyethyl methacrylate) (PHEMA) and poly(titanium oxide) (–TiO2–)n obtained by solgel method in the presence of poly(oxypropylene glycol) (POPG) at various molar ratio of titanium (IV) isopropoxide (Ti(OPri)4) and water. It has been established that the phase separation in OI IPNs depends on the kinetics of PHEMA-component formation and it occurs through the mechanism of the spinodal decomposition. It has been shown that by varying the ratio of IPNs components, content of inorganic component and Ti(OPri)4/H2O molar ratio it is possible to control the phase separation process and obtain OI IPNs with a different phase structure.
Leprosy and Stigma in Hislop’s Maria
’
s Island
Authors: Menelaou Iakovos 
Published: May 2024

Abstract
In this article, we propose a reading of Victoria Hislop’s Maria
’
s Island through the lens of the medical humanities. The novel belongs to the literary genre of children’s literature and, thus, is meant to be read by children. However, its strong meanings make it an interesting read for the adult reader, as well as the scholar in the fields of literary studies, the medical humanities and medicine. The plot unfolds in the small Greek villages of Plaka and Spinalonga (in Crete) and revolves around a leprosy epidemic. As we are going to see, the locals viewed the disease as a “curse” and a “social stigma,” and not as a medical condition. After a historical account of the disease, its “shame” and “stigma,” we proceed with a detailed analysis of the novel and explain how these notions are manifested. We also analyse how Maria, Anna and Doctor Nikos Kyritsis (three key characters in the story) represent different values and perspectives. On the one hand, Anna reflects the mentality of a conservative society and the view that leprosy carries a social stigma. On the other hand, Maria and Nikos believe that leprosy should be seen like any other disease that needs treatment, and that the leprosy patient is not a “stigmatised” or a “cursed individual.” Maria and Nikos represent the medical community in the novel, as Maria becomes a nurse and Nikos is already a Doctor, and show how medicine, compassion and a feeling of understanding create a safe and secure environment for the patient. Memory and flashback are key elements in the story, as Maria, the main character of the novel, explains to her granddaughter what happened in her village many years ago.
Memory, Self-Deception and Denial in Kazuo Ishiguro’s the Remains of the Day
Authors: Mureşan Dorel-Aurel 
Published: May 2024

Abstract
Kazuo Ishiguro’s novel The Remains of the Day delves into the intricacies of memory, self-deception, and denial through the lens of its protagonist, Stevens, a devoted butler. This article meticulously examines the interplay of these themes within the novel, elucidating their profound impact on Stevens’ identity and worldview. By meticulously dissecting Ishiguro’s narrative, the paper elucidates how memory functions as a tool for constructing personal narratives, particularly evident in Stevens’ selective recollection of events to maintain his idealized butler persona. Furthermore, it explores Stevens’ unwavering commitment to duty, which leads to his blindness towards his employer’s moral failings and the subsequent isolation and regret he faces. Through a comprehensive analysis, this paper argues that Stevens’ self-deception and denial emanate from a quest for dignity and purpose, underscoring Ishiguro’s critique of sacrificing integrity for societal conformity. Moreover, it elucidates how Ishiguro’s exploration resonates with broader philosophical discourse on memory, identity, and ethical considerations, accentuating the imperative of acknowledging past errors for individual growth and societal advancement.
