Published: February 2023

Electron beam annealing was carried out to form amorphous and crystalline germanium clusters in GeO[SiO] and GeO[SiO2] films deposited on quartz and monocrystalline silicon substrates. Using electron microscopy, Raman spectroscopy, and light transmission and reflection spectroscopy, the structural transformations of the films and their optical properties were studied. From the analysis of Raman spectra, it was shown that amorphous germanium nanoclusters are present in the as-deposited GeO[SiO] film, while they are not observed in the as-deposited GeO[SiO2] film. Regimes of electron beam annealing which are necessary for the formation of germanium nanocrystals in GeO[SiO] and GeO[SiO2] films were found. It was shown that, at the same annealing parameters, the fraction of the crystalline phase of germanium in GeO[SiO] films were smaller than in GeO[SiO2] films. In addition, it was found that the fraction of the crystalline phase at the same annealing parameters is larger for films on a quartz substrate than on monocrystalline silicon substrate. The sizes of germanium nanocrystals formed as a result of electron beam annealing were determined from Raman spectra analysis. The proposed method of obtaining amorphous germanium nanoclusters and nanocrystals in films of nonstoichiometric germanosilicate glasses using electron beam annealing can be used to create ordered arrays of such nanostructures. Keywords: films of nonstoichiometric germanosilicate glass, electron beam annealing, germanium nanoclusters and nanocrystals.

Published: February 2023

Earlier research proved that organizational productivity depends on the implementation of HR practices.  Companies grow high by adopting high-performance-oriented practices. The purpose of this study is to see how the employer-employee relationship affected employee engagement and task performance in food processing plants in Hyderabad. One of the most common HR practices is the employer-employee relationship, which is crucial in determining the employee level of engagement. Task performance refers to an employee's capacity to get things done, and it is backed up by the employer-employee relationship. To measure the influence of the employer-employee relationship on staff engagement and task performance, the researcher performed a study in two food processing plants in Hyderabad, India. To investigate the association between the dependent variables “employee engagement” and “task performance” and the independent variable “employer-employee relationship”, hypotheses were constructed. A questionnaire was circulated to respondents as a research instrument, and information was  collected from a sample of 100 people. It is inferred that the employer-employee relationship is significantly connected with employee engagement and negatively correlated with task performance. Gender is linked with all three variables and also with the profile factors. Employee engagement is connected to age, whereas task performance is negatively related to the employer-employee relationship. Statistical tools such as descriptive statistics, correlation, and ANOVA tests were used.
QUALITATIVE FEATURES OF WOMEN’S ENTREPRENEURIAL ACTIVITY IN THE REPUBLIC OF SERBIA: THE SECTORAL DISTRIBUTION PERSPECTIVE
Authors: Stošić Panić Danijela
Published: February 2023

Although growing in volume, women’s entrepreneurship is still significantly underrepresented relative to the entrepreneurial activities of men. Moreover, in most of the contexts, quantitative performance of female entrepreneurs are worse, compared to the ones achieved by their male counterparts. Though certainly important, knowing only the quantitative performance of female entrepreneurs is not enough for improving their competitiveness and socio-economic status. Quantitative performance are the results of certain qualitative features of women’s entrepreneurial activities, which are often neglected in the public discourse. The aim of the study is to provide an overview of the sectoral structure of women’s entrepreneurship from the less studied contexts, such Serbian environment is. Working with data provided by the Statistical Office of the Republic of Serbia, the study empirically tests and supports the hypotheses that there are differences in the sectoral distribution of female and male entrepreneurs in the Republic of Serbia, with Serbian female entrepreneurs being overrepresented in the services sector. Moreover, the results show women’s observed participation in the services sector is significantly higher than the one which would be expected given the sectoral structure of the general population of entrepreneurs. The paper discusses its theoretical and practical contributions as well.
THE MOST INFLUENTIAL ORGANIZATIONAL CHANGE MANAGEMENT MODELS FROM 1950 TO 2020
Authors: Vrcelj Nikolina , Karabašević Darjan
Published: February 2023

In the modern world economy, the survival of the organization increasingly depends on the ability of management to understand and manage change. The organization is constantly on the move and nothing should be considered static. Many diverse factors affect change, and few are under the control of the organization. The task of management is to understand the nature of changes, accept them, and direct them. However, there is no generally accepted model in the field of organizational change management. Many researchers and practitioners have failed to reach a consensus on which model is more effective for organizational change to be successful. This paper aims to identify the most influential organizational change models from 1950 to 2020. In order to identify them an analysis of 16 leading journals was carried out. The first 10 journals are listed on the Financial Times 50 list as the most influential in business and management and were selected for the analysis based on their relevance and scope (organizational change management). Other 6 journals were selected for the analysis as they are published by the world's prestigious academic institutions and have a high impact on the field of organizational change. Analysis of the journals in the period from 1950 to 2020 was performed, and 19 models of organizational change management that are relevant for this research were extracted. Afterward, an examination of domestic literature was conducted. There, three additional referent models were identified using the keywords: "model" and "change" within the research of the COBIB.SR database. The identified models of organizational change are then further analyzed and divided into three groups - process models that focus on the actual steps or phases of the change - 14 models, structural models that discuss the factors of change - 5 models; and integrated ones that use a combination of the previous two approaches - 3 models.

Con la finalidad de evaluar la presencia de insatisfacción corporal en jóvenes varones, resulta importante contar con instrumentos adecuados que midan esta insatisfacción y que garanticen resultados válidos. En el Perú y en diversos países, no se cuenta con gran variedad de herramientas apropiadas que midan la insatisfacción de la imagen corporal en varones, por lo que el propósito de la investigación fue adaptar el Body Shape Questionnaire (BSQ) en un grupo de jóvenes varones universitarios (n=320) de Lima Metropolitana con un rango de edad de 18 a 30 años. Se obtuvo una explicación del 50.72% sobre la variabilidad del instrumento y los resultados mostraron una excelente consistencia interna en ambos factores: 1) Malestar Corporal Normativo (α= .88) y 2) Malestar Corporal Patológico (α= .87). Respecto a la validez convergente y divergente, el BSQ demostró una buena capacidad para determinar la presencia de insatisfacción de la imagen corporal denotando una convergencia positiva y significativa entre ambos factores del BSQ con el Afecto Negativo del PANAS, explicando como todos estos sentimientos negativos se encuentran presentes e influyen con la aparición de esta incomodidad. Se discuten las limitaciones y recomendaciones del estudio, y la dirección de futuras investigaciones.

Alat pembayaran atau uang terus mengalami inovasi dan berevolusi mulai dari bentuk tunai menjadi bentuk non tunai atau disebut juga uang elektronik. Kemunculan bitcoin sebagai salah satu dari virtual currency menimbulkan pro dan kontra di berbagai kalangan. Ada yang membolehkan ada pula yang mengharamkannya. Penelitian ini bertujuan untuk menjelaskan konsep mata uang dalam perspektif ekonomi Islam dengan menganalisis bitcoin sebagai salah satu dari virtual currency. Metode yang digunakan dalam penelitian ini adalah metode kualitatif deskriptif. Sumber data diperoleh dari hasil wawancara dengan beberapa akademisi dari bidang ekonomi dan pihak regulator yaitu Bank Indonesia dan Otoritas Jasa Keuangan (OJK). Data dianalisis dengan mendeskripsikan konsep bitcoin sebagai mata uang virtual dalam perspektif ekonomi Islam. Hasil penelitian ini menjelaskan bahwa dalam ekonomi Islam mata uang harus memiliki underlying asset dan dijamin oleh pemerintah. Sedangkan bitcoin tidak memiliki underlying asset, tidak jelas siapa penerbitnya dan tidak ada yang bertanggung jawab. Banyak unsur ketidakjelasan yang dimiliki oleh bitcoin. Bahkan di Indonesia belum ada regulasi secara resmi dan masih dalam tahap pengkajian oleh para ulama. Oleh sebab itu, Bank Indonesia menghimbau kepada masyarakat untuk bertransaksi dengan rupiah karena sesuai dengan Undang-Undang No 7tahun 2011 tentang Mata Uang.

Published: February 2023

This investigation discusses the relationship between the body culture of movement and two rock art scenes located in the Parque Nacional Serra da Capivara, (Serra da Capivara National Park) - PNSC, in the state of Piauí, Brazil. The scenes depict a flic flac and a human pyramid, which have been accepted in contemporaneity as gymnastics and acrobatics. An interdisciplinary theoretical apparatus based on Physical Education and its relationships with Archeology and Anthropology was used in the analysis. The analysis is based on inferences, as nothing guarantees that the hands that portrayed the scenes had the same intentions as the authors of the research. One of the findings understands that motor skills helped the daily demands of adversity for the survival of the group. In another point of view, based on the Ilinx concept, flic flac satisfies the search for a trance/vertigo vital to ritualistic liturgy, and the human pyramid serves the imperative task of consolidating cooperative bonds and trust between its members in a hostile environment.
Integration of organoids in peptide drug discovery: rise of the high-throughput screening
Authors: Zhang Siqi , Shen Jieting , Wang Xingkai , Sun Xiaona , Wu Yuxuan , Zhang Ming-Rong , Wang Rui , kuan hu
Published: February 2023

Organoids are three-dimensional cell aggregates with near-physiologic
cell behaviors and can undergo long-term expansion in vitro. They are
amenable to high-throughput drug screening processes, which renders them
a viable preclinical model for drug development. The procedure of
organoid-based high-throughput screening has been extensively employed
to discover small molecule drugs, encompassing the steps of generating
organoids, examining efficient drugs in organoid cultures, and data
assessment. Compared to small molecules, peptides are more
straightforward to synthesize, can be modified chemically, and
demonstrate a high degree of target specificity and low cytotoxicity.
Therefore, they have emerged as promising carriers to deliver drugs to
disease-associated targets, and could be efficient therapeutic drugs for
various diseases. To date, organoids have been used to evaluate the
efficacy of certain peptide agents; however, no organoid-based
high-throughput screening of peptide drugs has been reported. Given the
advantages of peptide drugs, there is an urgent need to establish
organoid-based peptide high-throughput screening platforms. In this
review, we discuss the typical approach of screening small-molecular
drugs with the use of organoid cultures, as well as provide an overview
of the studies that have incorporated organoids in peptide research.
Drawing on the knowledge gained from small molecular screens, we explore
the difficulties and potential avenues for creating new platforms to
identify peptide agents using organoid models.

Authors: Yingzi Ming , Zhou Zhaoqin , Li Junhui , Jiang Jie , Luo Yulin
Published: February 2023

Background Immune cells are important for the development of
schistosomiasis japonica and are also critical for the treatment of
schistosomiasis. The immune cells in the peripheral blood help assess
the immune state. The peripheral lymphocytes in schistosomiasis mansoni
were well studied, however immune cells in patients with different
stages of Schistosomiasis Japonica are not well analyzed. Here we
performed a preliminary study to explore characteristics of peripheral
lymphocyte subsets in patients with different stages of Schistosomiasis
Japonica. Methods 135 patients with S. japonicum infection and
25 healthy volunteers were included in this study, including 84 patients
with chronic S. japonicum infection and 51 patients with advanced S.
japonicum infection. Flow cytometry analysis was performed to evaluate
peripheral lymphocytes including T cells, B cells and NK cells. Blood
routine and liver function test data were analyzed. Ultrasound
examination was used to access liver fibrosis according to the World
Health Organization standard about ultrasound in schistosomiasis.
Results Demographic data analysis suggested there was no
difference in age and gender in patients with S. japonicum infection and
health control group. Liver function tests showed that patients with
advanced schistosomiasis had a higher incidence of liver function
abnormality and blood lipid than those with chronic schistosomiasis.
Blood routine results reflected that hemoglobin, red blood cells,
platelets, as well as lymphocytes in the advanced group were
significantly less than that in the chronic group. Furthermore, flow
cytometry analysis indicated that the percentage of CD4
T cells was lower in the advanced group, but the
percentage of CD19 B cells was higher in the advanced
group. In addition, the number of CD3 T cells, CD3
CD4 T cells, CD3
CD8 T cells, and NK cells was less
in the advanced group when compared with those in the chronic group. In
addition, there was a correlation between the decrease in CD4
T cells and more severe fibrosis on ultrasound
images. Conclusion Our results indicated that the immune state
in the peripheral is different in different stages of S. japonicum
infection. Lymphocyte subset analysis have potential to facilitate
differential diagnosis of different stages of schistosomiasis japonica
and even to be a prognostic factor.

Published: February 2023

Background: Aging of the liver was regarded as a successful
adaptation or as a progressive disease state remains a matter of
controversy. This study aims to approach the mature investigation to
determine the mature effects of exercise training, resveratrol intake,
and the combination on SAMP8 mice liver. Methods: Histological
of 3- and 6-month-old SAMP8 mice were examined by H&E and Masson’s
trichrome staining. Apoptosis cells were determined by TUNEL staining.
Examine molecular protein of p-PI3K/PI3K, p-Akt/Akt, Bad, cytochrome c,
Bcl 2, ERK1, IL-6, STAT3, MEK5, p-ERK5/ERK5, FGF2, and MMP2 by western
blotting. Results: Results showed that the cross-sections of
6-month-old SAMP8 mice livers observed lower adipocytes, collagen, and
apoptosis cells appeared after exercise training, resveratrol intake,
and their combination than 3-month-old SAMP8 mice. Combination habitual
exercise training and resveratrol intake in the 6-month-old SAMP8 mice
liver has significant increases in p-PI3K/PI3K (p<0.001) and
p-Akt/Akt (p<0.01) ratios compared to 3-month-old SAMP8 mice.
Exercise training, resveratrol intake, and combined exercise training
and resveratrol intake facilitated ERK1-Bcl2 increases, and Bad,
Cytochrome c, IL-6-STAT3-MEK5-p-ERK5/ERK5 and FGF2-MMP2 decreases in the
6-month-old SAMP8, but not 3-month-old SAMP8 mice liver.
Conclusion: Fortunately, habitual exercise training and
resveratrol intake combination observed in the liver of mature SAMP8
mice at 6 months of age has an excellent good reversed age interaction
function in mature SAMP8 mice liver.

Published: February 2023

Understanding the relations between soil features and plant responses is important for agricultural production and nature conservation. The aim of this study was to investigate the importance of the influence of soils? physical and chemical features on the composition of plant species and richness in grasslands studied on the limestone massif in eastern Serbia (Mt. Rtanj). The data set included 22 phytosociological releves, the same number of corresponding mixed soil samples (0-10 cm depth) and 8 soil profiles. Two vegetation types were distinguished by numerical classification as Saturejion montanae and Festucion valesiacae. The results of detrended correspondence analysis (DCA) indicated that the most important soil parameters affecting species composition in dry grasslands were humus, the content of calcium, soil exchange capacity and base saturation, in addition to total acidity, pH and soil depth. The communities of both vegetation types are developed on Leptosols and Phaeozems. Under similar physical and chemical conditions of the soil, the grassland vegetation exhibits differences in floristic composition.

Test anxiety, coping, and academic achievement: Maladaptive perfectionism as a moderator
Authors: Genc Ana
Published: February 2023

The educational process is saturated with evaluative situations, which often
provoke a specific subtype of anxiety known as test anxiety. Since test
anxiety is not a reliable direct predictor of achievement, contemporary
research has consistently highlighted the need to explore how this
situation-specific trait indirectly affects success through various
mediation and moderation processes. The goal of this study was to determine
the existence and nature of complex moderated and mediated relationships
between the level of test anxiety, coping mechanisms, maladaptive
perfectionism, and academic achievement. The survey was conducted on a
sample of 263 students. The instruments used for data collection included
the Test Anxiety Inventory, the Coping Inventory for Task Stress, and the
Discrepancy subscale from the Almost Perfect Scale-Revised. Academic success
was expressed through the number of points achieved on a pre-exam knowledge
test. According to the results, maladaptive perfectionism proved to be a
statistically significant moderator in the relationship between test anxiety
and avoidance as a coping mechanism. In students with moderate maladaptive
perfectionism, test anxiety indirectly predicted lower achievement through
emotion-focused coping mechanisms. In subjects with high levels of
maladaptive perfectionism, test anxiety indirectly predicted better
performance through avoidance. The article discusses educational guidelines
for reducing the negative effects of test anxiety and maladaptive
perfectionism on achievement.

comprised nine class and subject teachers employed at two primary schools in
Belgrade. The research was conceived as a multiple-case study in which
thematic analysis was used as an auxiliary method for analyzing the data
obtained via a semi-structured interview. The criterion for the selection of
tense situations was the presence of one of the four types of tense
relations in the agonistic self: acceptance with critique, productive
tension, acute conflict, and permanent conflict. These relations were
interpreted as different forms of psychosocial dynamics and ways of
resolving psychological tension among participants. Subsequently, we
thematically categorized the selected situations. We identified nine themes
in relation to which our participants had professional dilemmas. Our
findings indicate that the same professional dilemma within a teacher?s self
can manifest itself in different kinds of tense relations. This suggests
that it is not sufficient to direct research attention towards the content
of the narratives about professional dilemmas, but that it is also necessary
to explore different mechanisms of psychosocial dynamics through which these
tensions develop and get resolved. This perspective on teachers?
professional dilemmas represents a contribution to the creation of new
models and the refinement of existing models of teacher professional
development.

Published: February 2023

The state of emergency was declared in Serbia in the spring of 2020 due to
the pandemic of the new disease, COVID-19. As a result, distance learning
was introduced for the first time at Serbian universities - online learning
in utterly specific crisis circumstances caused by the outbreak of the
pandemic of a completely unknown infectious disease. This model of learning
was adjusted to that fact in the form of emergency remote teaching. The
paper presents the results of examining the attitudes of female students of
teacher education faculties in Serbia regarding the efficiency and
sustainability of the distance learning model in which they gained
experience. The sample included 399 female students, who completed an online
survey designed for the purposes of this research. The results of the survey
showed the strengths and weaknesses of distance learning as a formerly
untapped potential in higher education in Serbia, which specifically refers
to the teaching model applied during the state of emergency introduced due
to the crisis caused by the COVID-19 pandemic. Also, the differences in the
knowledge of digital technologies by the professors came to the fore in
terms of the methods that the professors used in their work. The results
suggest that distance learning can be a useful tool in the process of
knowledge transfer in higher education, but that final year students are
most affected by the inability to acquire knowledge in practice that cannot
be virtually compensated, which is a very important step in their work
training, as well as the pronounced general problem of lack of social
interaction and meeting social needs, arising as a result of the pandemic.
In contrast, increased leisure time and health reasons stand out as the main
advantages of the new teaching model, which is significantly characterized
by the crisis environment.

LIV Golf and PGA Tour: Reinvigorated Issue of Antitrust in Sport
Authors: Alrefaei S. J. D Ammar
Published: February 2023

LIV Golf is a professional golf tour launched by the Saudi Public Investment Fund as a competitor to the PGA Tour. Prior to the first event of the LIV in June 2022, PGA had warned that it would sanction golfers participating in conflicting to PGA LIV events. It later suspended the LIV event participants from PGA and associated tournaments. In August 2022, a group of suspended golfers filed an antitrust lawsuit in the US demanding reinstatement in the PGA tour. They were joined by LIV which claimed that such suspension practices would destroy its “ability to maintain a meaningful competitive presence in the markets.” The US Department of Justice also launched an inquiry into the case. The primary issue in the matter seems to be whether PGA’s reaction to LIV consists of legitimate business protection or monopolist practices. This paper attempts to answer this question based on review of the relevant antitrust legal framework in the US. Additionally, the paper will look into possible implications of the likely court decision for golf and professional sports overall.

The problem of optimising financial relations in the budgetary system with respect to its vertical and horizontal structure often manifests itself in the form of vertical and horizontal fiscal imbalances, when the revenues of public administration units at its different levels or at the same level do not correspond to the expenditures related to the performance of the delegated responsibilities. The aim of the study is to map, using the case study method, the problem of vertical fiscal imbalance in the performance of delegated responsibilities at the level of local self-government in the Slovak Republic. Research ousomes show that municipalities overwhelmingly do not know the costs of performing delegated responsibilities (cost-center accouting is notu sed) , and thus we cannot legitimately determine vertical fiscsal imbalance scope. Identifying the sope of vertical fiscal imbalance througth the cost-center accouting is the starting point for its solution by the functionalisation of inter-level financial relations so that the revenues of public administration units at its different levels correspond to the expenditures associated with the performance of the delgated responsibilities.
