Isa Boletini (1864-1916): An Ottoman Albanian Figure of Twists and Turns
Authors: Ferko Beria Kafali
Published: February 2024

sa Boletini is one of the figures of Ottoman Empire with multiple identities and loyalties at the turn of the twentieth century. He was born in the village of Boletin near Mitroviçe during the transformation of the last Ottoman land in the Balkans into an independent state of Albania. He was one of the local figures who felt the foreign pressure in the region by the Great Powers and tackled them in his own ways which resulted in diplomatic crises between the Ottoman and Russian Empires. As a local power magnet, he was invited to the Palace to serve as a personal guard, tüfenkçi, to the Sultan Abdülhamid II. Endowed with privileges and concessions, he returned to his hometown where he became a gendarme of the Sultan and continued to exercise his authority within the limits. However, with the success of the 1908 Revolution by the Young Turks, the new regime targeted him and aimed to diminish the symbolism he carried as an old ally of the Sultan. Yet, in the tumultuous environment of the Balkans, perpetuating further violence turned the region into a more vulnerable land in the eyes of the Great Powers. This thesis aims to show the parallelism between the fluctuating events of the Balkans in nineteenth century and Isa Boletini’s multiple identities, in the light of the “Imperial Biography” approach, by making use of Ottoman archival material which was not yet incorporated into the study of his life.

The study carried out qualitative and bibliographical research seeking to highlight the main questions raised by high school teachers regarding Sexuality Education in schools. A survey of articles published between 2013 and 2022, in Portuguese, was carried out on the Periodicals Portal of the Coordination for the Improvement of Higher Education Personnel (Capes). The descriptors “Sexual Education”, “High School” and “teachers” were used and the analysis is based on Bardin’s proposal. The chosen works present in their summary references to the theme of Sexuality Education in High Schools. The results pointed to the unpreparedness and insecurity of teachers to deal with students’ manifestations and doubts on the topic of sexuality, as well as Sexuality Education being carried out only in the contents of human reproduction, contraceptive methods, prevention of pregnancy and sexually transmitted infections. The need for investments in continued training stands out so that this theme can be exercised inside and outside the school environment, as one of the means for restoring Education in all its configurations and knowledge.
O COMPLEXO CLÍNICO ORIUNDO DOS DISTÚRBIOS DA TIREÓIDE: UMA ABORDAGEM GERAL
Authors: Pulcino Tarciany das Neves
Published: February 2024

The thyroid is na endocrine gland, subject to hormonal stimulation, that is, by the hormone TSH, which is synthesized by the pituitary gland and sent to the thyroid via the bloodstream, thus synthesizing the hormones T4 (thyroxine) and T3 (triiodothyronine), which are responsible for control metabolic functions. Dysfunctions can occur such as hypothyroidism and hyperthyroidism, which are associated with factors such as pregnancy, aging, autoimmune disease and drug interactions with a certain type of drug, all of which can disrupt hormonal levels. Excessive or insufficient production of thyroid hormones can cause pathologies secondary to thyroid dysfunction. Therefore, knowledge about the proper functioning of the thyroid gland is essential, seeking to preserve homeostasis and, subsequently, a better quality of life for the patient. The diagnosis, that in both conditions, serum levels of Thyroid Stimulating Hormone (TSH) and thyroid hormone are essential for this, and treatment are essential for the patient to lead a normal life. The objective was to carry out a literature review on general aspects of the clinical complex arising from thyroid disorders, addressing the respective diagnosis and treatment.

Processos Administrativos na Administração Pública
Authors: Silva José Tadeu
Published: February 2024

With the increasing computerization of public administration, administrative processes have followed the trend of electronic management, through systems that allow its processing faster and more transparent, additionally adding greater productivity and effi ciency. This virtually irreversible movement establishes the necessary conditions for major innovations, as it allows knowledge engineering techniques to be applied to repositories inexorably formed by large volumes of data, either for their improvement towards better citizen service or as a support to public servants in decision making. This article seeks to probe, through a systematic review of scientifi c literature, how academic research has addressed the theme of the use of knowledge engineering about digital administrative processes in recent years.
To what extent do Brazilian NGOs in the state of Pará choose their organisation/ project locations based on assessed need?
Authors: Seibel Konrad Franz
Published: February 2024

Following democratizing reforms and the introduction of new legislation in the late 1990s, NGOs in Brazil underwent a series of shifts regarding their funding and relationship with the government. In this context, this research project investigates the motivations for location choice of NGOs in the Brazilian state of Pará using a theoretical framework consisting of three theories. While the research project aims primarily to investigate to what extent the needs-based hypothesis applies, it will also engage with the self-interest motivation and the political connectivity motivation. Based on a mixed methods research methodology consisting of a regression analysis and multiple semi-structured interviews with NGO directors, this research comes to the conclusion that there is little quantitative evidence for clustering based on need on a national level, but fi nds an NGO sector reporting a very high commitment to the need-based hypothesis which is arguably not realized due to extensive funding and infrastructure constraints and an inability to account for duplication eff orts. While the overall relationship between NGOs and the public sector is fraught, personal relationships and boundary-crossing are perceived as advantageous for gaining access to funding, though more explicit forms of rent-seeking behaviour are not reported.

Graphics-processing-unit-accelerated ice flow solver for unstructured meshes using the Shallow-Shelf Approximation (FastIceFlo v1.0.1)
Authors: Sandip Anjali , Räss Ludovic , Morlighem Mathieu
Published: February 2024

Abstract. Ice-sheet flow models capable of accurately projecting their future mass balance constitute tools to improve flood risk assessment and assist sea-level rise mitigation associated with enhanced ice discharge. Some processes that need to be captured, such as grounding-line migration, require high spatial resolution (under the kilometer scale). Conventional ice flow models mainly execute on central processing units (CPUs), which feature limited parallel processing capabilities and peak memory bandwidth. This may hinder model scalability and result in long run times, requiring significant computational resources. As an alternative, graphics processing units (GPUs) are ideally suited for high spatial resolution, as the calculations can be performed concurrently by thousands of threads, processing most of the computational domain simultaneously. In this study, we combine a GPU-based approach with the pseudo-transient (PT) method, an accelerated iterative and matrix-free solution strategy, and investigate its performance for finite elements and unstructured meshes with application to two-dimensional (2-D) models of real glaciers at a regional scale. For both the Jakobshavn and Pine Island glacier models, the number of nonlinear PT iterations required to converge a given number of vertices (N) scales in the order of 𝒪(N1.2) or better. We further compare the performance of the PT CUDA C implementation with a standard finite-element CPU-based implementation using the price-to-performance metric. The price of a single Tesla V100 GPU is 1.5 times that of two Intel Xeon Gold 6140 CPUs. We expect a minimum speedup of at least 1.5 times to justify the Tesla V100 GPU price to performance. Our developments result in a GPU-based implementation that achieves this goal with a speedup beyond 1.5 times. This study represents a first step toward leveraging GPU processing power, enabling more accurate polar ice discharge predictions. The insights gained will benefit efforts to diminish spatial resolution constraints at higher computing performance. The higher computing performance will allow for ensembles of ice-sheet flow simulations to be run at the continental scale and higher resolution, a previously challenging task. The advances will further enable the quantification of model sensitivity to changes in upcoming climate forcings. These findings will significantly benefit process-oriented sea-level-projection studies over the coming decades.

Anionic molecules play essential roles in our biology, controlled by a complex system of proteins that when something goes wrong, critical health problems can arise. This thesis combined computational tools and laboratory-based assays to investigate how some of these proteins recognize molecules and attempt to find small molecules that could help address these health problems. The three publications each study a different protein – LexA, which helps bacteria develop antibiotic resistance; human single-stranded binding protein 1, implicated in cancer; and the SARS-CoV-2 spike protein, studying how it infects cells.
Smart urban governance for more-than-human future(s)
Authors:   , Sheikh Hira
Published: February 2024

Environmental change is giving rise to the inclusion of multispecies justice in urban discourse and practice. At the same time, ‘smart’ thinking/practice about cities driven by technocratic approaches, has been critiqued for reinforcing human exceptionalism. That is, nonhuman nature in cities is increasingly perceived and governed via digital technologies that rarely account for limits to human perception. This doctoral thesis offers an alternative and addresses how digital technologies and politics can be reconfigured to care for the nonhuman species in cities.
“Lejos del polvo” en el Discurso acerca de la pintura de Shitao: Soledad en el arte chino
Authors: Rongqiao Wu , Yan He
Published: February 2024

“Lejos del polvo” es un concepto importante en el sistema pictórico de Shitao, que cristaliza su profunda reflexión sobre la interrelación entre el arte, el individuo, la sociedad y la naturaleza. Este artículo tiene como objetivo analizar la rica semántica de este concepto. En este estudio se revelará que la afirmación de “Lejos del polvo” no implica una segregación del individuo con la sociedad mundana, ni tampoco una evasión de las suciedades de la vida terrenal. Este concepto pictórico se enmarca en la filosofía de la soledad en el arte chino. Mediante la no adhesión a lo impuro y lo puro, el artista crea un estado de observación sereno y contemplativo que permite vislumbrar la esencia del arte. En este estado, se logra superar las limitaciones temporales y espaciales, hasta que se disuelve la dicotomía entre el sujeto y el objeto. Esta tríada semántica se entrelaza en una cadena de significados que apuntan al ideal supremo del paisajismo, que es el tao.
La plástica comunista chilena ante el Realismo Socialista durante el preámbulo de la Guerra Fría (1948-1952)
Authors: Lewin Velasco Josefina
Published: February 2024

Este artículo analiza la plástica comunista chilena en la época de la persecución anticomunista desatada por el presidente Gabriel González Videla (1948-1952). Más precisamente, proponemos estudiar las prácticas de los artistas visuales que fueron consagrados en el seno de la cultura comunista chilena de lado de los discursos del arte (reflexiones, debates y críticas de arte) que circularon en los medios del PCCh en esta época. Nuestro principal objetivo será dilucidar los encuentros y desencuentros entre la cultura plástica del PCCh y el realismo socialista, que alcanzó su formulación más dogmática precisamente en el contexto de la temprana Guerra Fría.  Así, pues, se tratará de pensar el problema de la recepción de la teoría estética soviética en las plataformas del PCCh, sin perder de vista las inclinaciones “localistas” de la plástica comunista chilena o los problemas asociados a la propia exportabilidad del realismo socialista.
Análisis del impacto emocional del Síndrome de Rett en el contexto familiar
Authors: Galán González Nuria , Fontana Abad Mónica
Published: February 2024

Introducción.   Las investigaciones sobre el Síndrome de Rett se han centrado mayoritariamente en su conocimiento a nivel clínico, ofreciendo escasa información del contexto familiar. Considerando este vacío en la literatura científica, se propone un estudio cuyo objetivo es analizar el impacto emocional que provoca el Síndrome de Rett (incluyendo el ámbito de la Atención Temprana) en la familia. Método.  Se analizan cuatro variables relacionadas con el impacto emocional (ansiedad, depresión, inadaptación y resiliencia) mediante un diseño de tipo descriptivo-correlacional expostfacto. La muestra está compuesta por 222 familiares directos de una persona con Síndrome de Rett en España. Resultados.  Las familias vinculadas al Síndrome manifiestan niveles altos de ansiedad e inadaptación y a la vez resiliencia, frente a baja prevalencia de trastorno depresivo. Por otra parte, la edad de diagnóstico es tardía (5 años), prolongando el impacto emocional en el sistema familiar y dificultando su adaptación ante la nueva situación. Discusión y conclusiones. Valorando el impacto emocional de los familiares a través del análisis de las variables de interés del estudio, se concluye que la presencia de ansiedad e inadaptación es una realidad que forma parte de las familias que conviven con esta alteración, lo que conlleva a experimentar dificultades para afrontar el Síndrome y asimilar los nuevos cambios surgidos en el sistema familiar. Al mismo tiempo, la resiliencia ha mostrado una gran representatividad (al contrario que la depresión), concluyendo que familiares que conviven con el Síndrome de Rett siguen un perfil de familiares resilientes con capacidad de superar situaciones de presión, que buscan el equilibrio emocional y control.

Провели компьютерное моделирование процессов трех- и четырехвалковой винтовой прокатки с помощью вычислительной среды конечно-элементного анализа QForm при постоянном и переменном факторе трения для пар «валок–заготовка». По результатам моделирования при постоянном факторе трения установили, что в продольном сечении заготовки после четырехвалковой прокатки среднее значение накопленной деформации выше по сравнению с трехвалковой прокаткой, деформация проникает глубже в заготовку. Также определили, что при постоянном и переменном факторе трения четырехвалковая прокатка протекает быстрее, чем трехвалковая. Анализ оценки скорости перемещения заготовки при трехвалковой и четырхвалковой прокатке позволил установить, что при четырехвалковой винтовой прокатке после резкого падения скорости вследствие недостаточного трения между валком и заготовкой возврат к устойчивому протеканию процесса наступает быстрее, чем при трехвалковой прокатке.

Finite element method computer simulation of three- and four-high screw rolling was done using QForm software. Computer simulation was carried out in terms of constant and variable friction for the “roll–billet” pair. Results of computer simulation at constant friction showed that mean value of accumulated strain for the longitudinal section of billet is higher after four-hogh screw rolling compared to same after three-high screw rolling. It means that deformation penetrates deeper while four-high screw rolling. It was also established that four-high screw rolling occurs faster than threehigh screw rolling at variable friction condition. Analysis of billets displacement at three- and four-high screw rolling allowed estimating that after sharp decrease of rolling velocity due insufficient friction return to stationary rolling process at four-high rolling occurs faster than at three-high screw rolling.

Приведены результаты экспериментальных исследований по влиянию лазерного излучения на глубину закаленного слоя вырубных штампов, изготовленных из углеродистой и легированных инструментальных сталей У8, 40ХН2МА, 5ХВ2С, 9ХС и ХI2М, которые показали, что после лазерной закалки количество остаточного аустенита в 1,5–2,5 раза больше, чем после объемной. Установлено, что после лазерной обработки стали различных структурных групп имеют различную глубину и твердость закаленного слоя, при этом наибольшей глубиной и твердостью обладают эвтектоидная сталь У8 и заэвтектоидная сталь 9ХС, а наименьшей – доэвтектоидная сталь 40ХН2МА и ледебуритная сталь Х12М. В результате обработки опытных данных показано, что глубина первой зоны упрочненного слоя в первом приближении пропорциональна коэффициенту теплопроводности. Для изготовления деталей, которым по условиям эксплуатации требуется большая глубина упрочненного слоя, можно рекомендовать стали с повышенным содержанием кремния, особенно, в поверхностном слое.

The results of experimental studies on the effect of laser radiation on the depth of the hardened layer of trunched dies made of carbon and alloy tool steels U8, 40HN2MA, 5ХВ2С, 9ХС and XI2М are presented, which showed that after laser hardening, the amount of residual austenite is 1.5–2.5 times more than after volumetric. It was established that after laser processing, steels of various structural groups have different depth and hardness of the hardened layer, while the highest depth and hardness are eutectoid steel U8 and zaeuthectoid steel 9XC, and the smallest – pre-eutectoid steel 40HN2MA and ledeburite steel X12M. As a result of processing experimental data, it is shown that the depth of the first zone of the hardened layer in the first approximation is proportional to the coefficient of thermal conductivity. For the manufacture of parts that, according to the operating conditions, require a large depth of the hardened layer, it is possible to recommend steels with a high silicon content, especially in the surface layer.

Published: February 2024

Employee turn-over is often associated with “employee retention”. Employee retention plays an important role to keep up with other companies amidst the rapid evolvement of global economic environment. The objectives of the study are to understand the importance of employee retention, assess the factors affecting retention of private employees in Cambodia such as compensation, promotion and opportunity and growth; work environment, training and development and work-life balance and job satisfaction thus provide suggestions to private companies on what to undertake to retain its employees. The researcher employed model synthesis to determine the factors affecting employee retention from previous researches. Then, the researcher applied Delphi method technique to identify the significant factors according the experts. Pilot testing was conducted with 43 sample size. After pilot testing, the researcher surveyed 420 respondents using disproportionate stratified random sampling technique equally distributed to financial services, manufacturing, tourism and hospitality industry; education, retails and others (professional services, hospital, construction etc.). However, there were only 410 samples qualified to the analysis. The research model and research hypothesis were successfully tested by Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM) using SPSS and Amos 26. Based on the study “job satisfaction” is driven by compensation and work-life balance. They are the significant and the most influencing factors that make private employees stay in a company. Work environment, promotion, opportunity and growth; and training and development are the least significant factors affecting employee retention. However, according to the experts during in-depth interview, the factors vary from one person to another individual needs.
Farmer’s Attitudes on pesticide-use and pest-management practices: A case study of vegetable-cultivators in the vicinity of Lucknow, India
Authors: Kumar Pradeep , LNU Dipti , Singh Rana Pratap
Published: February 2024

For effective pest management, farmer’s awareness of pesticide toxicity and its safe application is crucial. The use of pesticides in vegetables and fruits is increasing day by day. To assess the awareness of the vegetable and cereal growers in Uttar Pradesh, India on the safety and toxicity management of chemical pesticides, a household survey was carried out using a well-structured questionnaire. According to our survey and observation, more than 99% of farmers preferred chemical pesticides to other alternative approaches for controlling pests. Notably, 80% of farmers were unaware of the harmful consequences that chemical pesticides have on human health and the environment. Nearly 40% of farmers had at least some brief training in integrated pest management (i.e., Communicated through the Kisan Mela and agricultural experts), however, none of them were conscious of the negative effects of pesticide residue or appropriate disposal strategies. For technical information on the selection, handling, and use of pesticides, more than 90% of growers seem to be dependent on local pesticide retailers, radio, and television.

Authors: Dr. Ranjana Sharma Dr. Devendra Kumar Dixit,
Published: February 2024

In the digital era, the advent of electronic payment systems has revolutionized financial transactions, with significant implications for financial inclusion. This research paper delves into the dynamics of digital payment methods and their impact on financial inclusion in India, focusing on user demographics, adoption rates, perceptions, and barriers to usage.

The study was underpinned by several research objectives aimed at understanding the nuances of digital payment adoption across different demographic segments, assessing the perception of security and privacy, evaluating the role of digital payments in reducing cash dependency, identifying the adoption barriers, and recommending inclusive strategies for broader access. A set of research questions and hypotheses were formulated in line with these objectives.

A quantitative research approach was employed, involving a survey disseminated across multiple Indian states. The survey, comprising structured questionnaires, targeted a diverse population segment, accumulating a total of 500 responses. The data collected was rigorously analyzed using descriptive statistics, inferential tests (t-tests and ANOVA), and thematic analysis for open-ended responses.

Key findings of the study indicated a higher propensity for digital payment adoption among younger individuals, with notable hesitancy among older demographics. Security and privacy concerns were prevalent, significantly influencing user behavior, particularly among females. The research also highlighted a substantial reduction in cash dependency among digital payment users, indicating an increase in financial autonomy. However, significant barriers, including digital literacy, infrastructure inadequacies, and language barriers, especially in rural areas, impede widespread adoption.

These findings have profound implications for financial inclusion, emphasizing the need for a multifaceted approach to address the digital divide. The study underscores the necessity for stakeholder collaboration in enhancing digital infrastructure, literacy, and trust, thereby fostering an inclusive financial environment. The insights derived are of paramount importance for policymakers, financial institutions, and fintech companies aiming to innovate and expand the reach of digital financial services.
Community assembly of the human piercing microbiome
Authors: Xu Charles , Barrett Rowan
Published: February 2024

Predicting how biological communities respond to disturbance requires understanding the forces that govern their assembly. We propose using human skin piercings as a model system for studying community assembly after rapid environmental change. Local skin sterilization provides a ‘clean slate’ within the novel ecological niche created by the piercing. Stochastic assembly processes can dominate skin microbiomes due to the influence of environmental exposure on local dispersal, but deterministic processes might play a greater role within occluded skin piercings if piercing habitats impose strong selection pressures on colonizing species. Here we explore the human ear-piercing microbiome and demonstrate that community assembly is predominantly stochastic but becomes significantly more deterministic with time, producing increasingly diverse and ecologically complex communities. We also observed changes in two dominant and medically relevant antagonists (*Cutibacterium acnes* and *Staphylococcus epidermidis*), consistent with competitive exclusion induced by a transition from sebaceous to moist environments. By exploiting this common yet uniquely human practice, we show that skin piercings are not just culturally significant but also represent ecosystem engineering on the human body. The novel habitats and communities that skin piercings produce may provide general insights into biological responses to environmental disturbances with implications for both ecosystem and human health.

Boga-TN is a formula originating from herbal medicines that are used to treat liver disorders; however, its toxicity is not yet investigated. Therefore, this study  was conducted to assess the acute and sub-chronic toxicity of Boga-TN tablets in experimental animals. Acute toxicity study was performed  via Swiss mice, with a single oral dose, and followed up to seven days according to World Health Organization Guidance. No sign of acute oral toxicity was detected, and the LD50 Boga-TN was estimated to be more than 60.38 g/kg. Based onobtained results , the sub-chronic toxicity study was carried out in Wistar rats for 4 consecutive weeks by oral administration at the doses of 0.77 and 2.31 g/kg/day. After treatment, no significant treatment-related abnormalities were observed at both doses of Boga-TN, compared to the control group, except  lower neutrophil but higher lymphocyte values were observed in the treated animals. Histopathology assessment did not show any significant variation between control and treatment groups during the study period.

We evaluate the acute and subchronic toxicities of “Com kien ty” through oral administration in experimental animals. The acute toxicity was determined using the Litchfield Wilcoxon method in mice. Following WHO's recommendation, the subchronic toxicity was assessed in rabbits with oral doses of 0.9 g/kg/day (equal to the recommended human dose) and 2.7 g/kg/day (3 times as high as the recommended human dose) in 4 consecutive weeks. Results showed “Com kien ty” at the highest dose of 60.0 g/kg did not express acute toxicity in mice. Regarding the subchronic toxicity test, after oral administration of “Com kien ty”, hematological parameters, hepato-renal functions were unchanged as compared with the control group, and no gross lesions in organs were observed in all experimental animals. In conclusion, “Com kien ty” did not produce acute and subchronic toxicities in Swiss mice and New Zealand rabbits.

Knee osteoarthritis is one of the most common joint disorders of older individuals. It is a painful and disabling disease characterized by pain, stiffness. However, in Vietnam, the number of studies on this issue is still very limited, especially those on physical function. Objective: This study aimed to evaluate physical function in 178 elderly patients with knee OA. A cross-sectional study was utilized. Physical function was assessed by The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Timed up and go test (TUG). Mean total WOMAC scores of older patients with knee OA in the study was: 34.67 (± 15.63). The proportion of older patients with knee OA with impaired mobility (assessed by TUG test) was 64.8%. The mean total WOMAC scores were more likely to be higher in the elderly with knee OA whohave advanced age, living with others (family, caregiver), overweight/obese or underweight, poor nutritional status, no sleep disturbance, more pain, inflammatory pain and had no treatment for knee OA. There was a decrease in physical function in patients with osteoarthritis of the knee. Mobility impairment was associated with the level of pain, and treatment of knee OA or lack of.

El Infanticidio. Configuración legal y aplicación jurisprudencial de un delito de honor en el Derecho Penal histórico español (1822-1995)
Authors: Ramos Vázquez Isabel
Published: February 2024

A principios del siglo xix, los principios humanitarios y utilitaristas que alumbraron el primer Código penal español de 1822, dieron lugar a la configuración legal de un nuevo delito, el infanticidio, que se mantuvo con escasas modificaciones en el ordenamiento jurídico español a lo largo de los siglos xix y xx, hasta la promulgación del Código penal de 1995. Este trabajo de investigación pretende analizar los argumentos jurídicos que sustentaron la configuración legal de este especial delito de honor en los distintos Códigos penales contemporáneos (Códigos penales de 1822, 1848-1850, 1870, 1928, 1932, 1944, y sus reformas de 1963, 1973 y 1983), y la aplicación del mismo a través del estudio de la autorizada jurisprudencia del Tribunal Supremo.
