The aim of this study is to examine employee motivation and its influence on job satisfaction. As a result of the fact that people and the information they possess are the most essential factors determining the productivity of an organization, motivation is becoming an increasingly vital component of modern business. One of the most important parts of motivation is determining how satisfied employees are with their jobs. As a necessary first step for achieving higher levels of efficiency, responsiveness, quality, and recognized service, businesses have an obligation to ensure that their staff members report high levels of job satisfaction. The goal of this thesis is to investigate the level of contentment and drive experienced by workers. It also discusses the impact that the company's culture has on the level of satisfaction experienced by the staff. Concepts like job satisfaction, different types of motivation, and different types of incentives are included in the theoretical framework of this thesis. The relationship between the employees and the management, as well as the communication that exists between the two groups, is one of the organization's greatest strengths.

Published: December 2022

La pandemia global de Covid-19, declarada en México a partir de marzo de 2020, puso en jaque la vida. Por casi dos años los espacios físicos de la universidad fueron abandonados. Ahora, con el regreso presencial a las aulas, las autoras de este texto se preguntan de qué manera se volverán a habitar las aulas. En la Facultad de Filosofía y Letras de la UNAM resuena una voz que exige un giro pedagógico restaurativo que permita la transformación de las dinámicas –muchas veces violentas– y las relaciones sociales, culturales y académicas que, antes de la pandemia, llevaron a la universidad al silencio, la ausencia y la desesperanza. Este texto expone las experiencias vividas dentro del Círculo Errante, un espacio para desenvolverse libremente entre los procesos de formación individual y colectiva. Las autoras presentan un lugar seguro para (des)aprender formas de construir conocimientos y así restaurar el tejido comunitario de la universidad.

Published: December 2022

The retention period of the drug and dosage form in the stomach is very challenging for the treatment of gastrointestinal disease. To solve this problem and improve the efficacy and bioavailability of the drug, most researchers develop a novel carrier system that is called a Floating drug delivery system (FDDS).  The goal of this review on floating drug delivery systems (FDDS) is to synthesise contemporary material with a particular concentration on the main mechanism of flotation for stomach retention. The physiology of the stomach (including gastric pH and movement) has been shown a major effect on gastrointestinal holding period and drug delivery behaviour in both intra- and inter-subject variability. The most recent advancements in the Floating drug delivery system (FDDS) are thoroughly reviewed, including the physiological and formulation factors that influence stomach retention, design methods for single-unit and multiple-unit floating systems, and their categorization and formulation characteristics. A synopsis of the research that has been done to determine the effectiveness and utility of floating systems, as well as uses for such systems, is also included in this review. This study covers the most recent Floating drug delivery system (FDDS) technology advances, including patented delivery techniques and commercial devices, along with their benefits and potential applications for oral controlled drug administration in the future.

Looking for “The Best of all Worlds”: Using Different Teaching Formats in an English as an Additional Language Program
Authors:   University of Latvia, Ginzburg Tatiana , Daniela Linda
Published: December 2022

In spring of 2020, when the first Covid-19 related restrictions were introduced, educators were forced to rapidly look for new solutions. Most of those involved moving classes online. However, although quality was a concern for all institutions, ensuring a balance between safety and quality of education presented an additional challenge to providers of non-formal adult education. Therefore, developing a course to accommodate the new and, probably, enduring reality as well as carefully monitoring its delivery was essential. Even though different modalities have been used in education for decades, only now have they become a part of the mainstream. Most educators were used to working in either traditional face-to-face or online mode, while some students could have used a combination of both as well as other web-based resources. Thus, shifting from one modality to another or mixing them in a course presented certain challenges for both educators and students. This paper describes a blended hybrid program of English as an Additional Language for adults developed at RTU Riga Business School English Language Center in response to the Covid-19 pandemic. The program has the same basic content as previous face-to-face one but incorporates various carefully analyzed modalities. Specifically, it combines a face-to-face (F2F) and remote online synchronous learning, and adds asynchronous part to the course. It has been piloted in open public groups as well as corporate courses with student feedback analyzed vis-a-vis face-to-face courses. This paper analyzes the development of a program for open groups.
Types of Digital Learning Solutions Most Used by Educators in Latvia
Authors:   Riga Stradiņš University, Purina-Bieza Katrina Elizabete , Sarva Edīte ,   University of Latvia
Published: December 2022

Ongoing educational digitalization, as well as remote learning caused by the COVID-19 pandemic, has significantly promoted the use of digital technologies in education. Consequently, questions regarding the use of different digital solutions (DSs) have arisen, such as which DSs are best suited for teaching and learning, what types of digital learning solutions (DLSs) are freely accessible and what kinds of solutions are still insufficiently available to educators. The research questions were designed to answer (1) what kind of DSs educators are most interested in and (2) which DSs they have successfully implemented in their practice. To determine the answers to these questions, two separate data sets were combined. The first data set emerged from analysing site traffic data from the educational platform DigiKlase.lv, where DSs and educational resources that can be implemented in the teaching-learning process have been collected. The second data set was gathered during an educational technology mentor professional development course and from the Erasmus+ project “Network of technology INTEGRAtionists in pupils’ informal education” (INTEGRA) educators in Latvia, where 798 educators were surveyed about their success with implementing DSs in their educational practice. The results demonstrate that educators are most interested in electronic and digital teaching resources that are types of digital solutions with limited interactivity. Furthermore, educators are interested to further explore DLS that are accessible without registration, are free of charge, and contain methodological recommendations for using them in an educational setting. Nevertheless, instructions on how to use a DLS have a negative impact on their opening rate. Educators also prefer resources that are in the national language, visibly dismissing and not further exploring solutions that are in other widely used languages in Latvia, for example Russian or English. The data reveal that DSs are, overall, significantly less used in preschool settings and in subject areas that are not directly related to the usage of technology including solutions that could be used in any subject area like digital educational games, co-working documents etc. Furthermore, educators report that they have more successfully implemented DSs that emulate the analogue learning process, and fewer choose solutions that are related to working in a digital environment.
Syllabus and Learning Outcomes: A Case Study of Medical College Students’ And Lectures’ Experience
Authors:   University of Latvia, Svētiņa Karīna , Litiņa Sanita
Published: December 2022

Syllabus is an important document for higher education institutions. It is a normative requirement for the assessment of the quality and facilitates understanding between teachers and students on the course and requirements. An important section of syllabi is the learning outcomes that characterise what students need to be able to demonstrate after completing the course. The aim of this research is to find out to what extent students read syllabi, to find out students’ opinions about the learning outcomes to be achieved specified in the syllabus, as well as to analyse how lecturers introduce students to the content of the syllabus. The research consists of three stages: 1) compilation of statistics and analysis on the number of readings of syllabi; 2) analysis of students’ self-assessment of the learning outcomes to be achieved; 3) survey of lecturers on the process of the introduction of syllabi. In the results, it was concluded that in the 2nd academic year there are more students who have read the syllabi than in the 1st and 3rd academic year. It was discovered that 64% of students agree with the statement that the lecturer introduces the requirements of the study course and 56.5% of students agree that at the end of the study course they have achieved the learning outcomes specified in the syllabus. The results of lecturers’ surveys indicate that the vast majority 78.8.5% are convinced that only a few read the syllabi, 41.2% use the presentation, 5.9% create a separate report to introduce students to the syllabus and learning outcomes and 60.6% devote around 10 minutes to it. According to the obtained results, it would be necessary to encourage lecturers to devote more time when introducing students to the syllabus and to inform the lecturers about the feedback on the reading statistics of their syllabi.

Published: December 2022

he extreme situation connected with the outbreak of the pandemic coronavirus has forced foreign language teachers worldwide to challenge their teaching competences and approaches when teaching remotely. Now, more than ever, foreign language teachers are forced or encouraged to implement digital materials, learning objects and environments. Meanwhile, foreign language teachers’ knowledge, skills and attitudes related to Digital Citizenship Education (DCE) are tested and challenged, too. The aim of this paper is to explore how confident and knowledgeable about DCE foreign language teachers are in order to offer activities that can enhance the development of language learners’ digital citizenship competences. This study presents the survey findings of the ERASMUS+ project: “Digital Citizenship Education and Foreign Language Learning” (Dice.Lang), which brings together five European partner universities: University of Munich, University of Aveiro, University of Latvia, University of Limerick, and Siena Italian Studies. There were 627 foreign language teachers (312 pre-service teachers and 315 in-service teachers) in total who participated in the online survey representing Germany, Ireland, Italy, Latvia, and Portugal. The findings highlighted the needs foreign language teachers have to develop and apply their expertise on DCE in their language lessons. The authors of the paper present their vision to address the teachers’ needs, providing and analysing samples of a comprehensive set of open educational resources (OER) available in English and additional European languages. These OER, which have been designed by the Dice.Lang consortium and confirmed by the questionnaire results, aim at developing language learners’ digital citizenship competences. The resources intertwine the five DCE strands created by the consortium (Critical Digital Literacies; Intercultural and Transcultural Perspective on Digital Exchanges; Identity-oriented Component; Content-oriented Perspective and Critical and Meta-reflective Component) with the existing European theoretical frameworks.
Sufficient chloroplast DNA is necessary for germ cell development in Volvox powersii, an emerging model for the evolution of cellular differentiation
Authors: Siverio Belmarie , Ortiz Elysia , Grochau-Wright Zachariah
Published: December 2022

Germ-soma cellular differentiation plays a key role in the evolutionary
transition from single-celled individuality to multicellular
individuality. The volvocine green algae, with their relatively recent
origin of multicellularity and gradient in multicellular complexity
across closely related species, serves as a model system for studying
the evolution of multicellularity and cellular differentiation. Volvox
carteri is the best studied species in its genus and is consequently a
well-established model for the evolution of multicellular development.
However, V. carteri possesses a derived type two developmental program
in which cellular differentiation is determined by differences in cell
size that arise through asymmetric division. Compared to other Volvox
species, Volvox powersii is less studied and has ancestral features,
including a type one developmental program in which large gonidia
undergo rapid, symmetrical divisions with cellular differentiation
occurring after hatching. With the absence of asymmetrical divisions, in
contrast to the more derived type two developmental program, embryonic
cell size cannot be a valid determinant of cell fate. We hypothesized
that chloroplast DNA (cpDNA) inheritance may be a determining factor in
cell fate due to expression levels of photosynthetic genes varying
greatly among somatic and germ cells and greater amounts of chloroplast
DNA in germ cells. Using gyrase inhibitors Nalidixic acid and
Novobiocin, Volvox powersii cultures were manipulated to disrupt the
distribution of cpDNA throughout the colonies and analyze the resulting
distribution of cell types, the size of each cell, and the number of
offspring in consecutive generations. Our results indicate that there is
a specific amount of cpDNA that must be present in each cell to be able
to fully develop into a germ cell.

Published: December 2022

Climate change and shrub encroachment affect nematode biodiversity,
although shrub species had different effects on below-ground community.
Yet, the consequences of shrub species on the nematode beta diversity
under future climate change scenarios remain insufficiently explored.
Here, we studied the dominant shrub effects on the beta diversity of
soil nematode communities along climate gradients on the Qinghai-Tibet
Plateau. We investigated soil nematode communities in 31 sites of alpine
meadow ecosystems across a 1200 km × 1200 km area with widespread shrub
on the Qinghai-Tibet Plateau. We found that shrubs decreased the
nematode beta diversity through decreasing the nestedness component at
local and landscape scales. Leguminous shrubs had stronger effects on
the nematode beta diversity than non-leguminous shrub types at landscape
scale. MAP and MAT both significantly increased the negative shrub
effects on the nematode beta diversity, but they remained constant for
leguminous shrub. The pSEM analysis showed that shrubs had direct and
indirect effects on nematode beta diversity via plant species turnover.
Our results showed that shrub encroachment, particularly leguminous
shrubs, leads to the homogenization of nematode communities. The
“warming-wetting” trend will exacerbate shrub effects on the
homogenization of nematode communities on the Qinghai-Tibet Plateau. Our
study provides insight into the ecological processes that maintain soil
biodiversity and biogeographic patterns of soil communities on the
Qinghai-Tibet Plateau.
Nude mice inoculated with MT-2 cells supporting SIV replication in vivo：a small animal model for anti-HIV efficacy evaluation
Authors: Xie Lei , Chen Xiuyun , Yin Mingyu , Li Junlin , Huang Wenguan , Luo Minyi , Liu Yatian , He Haolan , He Jinyang
Published: December 2022

Background and Purpose: The previous humanized mouse model for HIV/AIDS
study loses the superiority of easy operation and justifiable cost. In
this study, an economical and easy-to-operate small animal model
supporting SIV replication in vivo was established. Experimental
approach: Three-week-old male BALB/c nude mice were transplanted with
SIV infected MT-2 cells by single intraperitoneal injection to establish
the SIV infection model. The change in plasma viral load and the
colonization of MT-2 cells in vivo were investigated. Changes of the
immune system were evaluated by ELISA assay and flow cytometry assay.
Results: The success rates of this model were 100% and all mice in the
model group had detectable plasma viral loads (4.98±0.35
~ 5.39±0.31 log10 SIV RNA copies / mL) in peripheral
blood. It is our speculation that the virus replication in mice was
mainly due to the proliferation of SIV-infected MT-2 cells that
distributed and colonized in abdominal cavities as well as lymph nodes,
releasing free virions to maintain infection. It is worth mentioning
that there was a statistically significant downtrend in the plasma viral
loads of the HAART group. Administration of HAART somewhat reversed this
trend of SIV-associated B cell exhaustion and immune collapse.
Conclusions and Implications: Therefore, it is reasonable to believe
that the model proposed in this study could be a valuable tool to
evaluate antiviral effects and immune regulation efficacy in vivo.
Flexible inventory system of imperfect production under deterioration and inflation
Authors: Sharma Archana , Singh Chaman , Verma Priyanka , Malik A.K.
Published: December 2022

This study emphasizes the development of a flexible inventory system considering rework requirements on imperfect and defective items. This work has
considered defective items could be sold at a lower price in the market as
compared to the perfect items. The developed model has considered Weibull
deterioration and inflation to balance the same amount in the future due to
its potential earning capacity. And demand's function depends on price as
well as inventory level because a large pile of goods and their price
strategy attracts more customers to generate higher demand. The work also
supports managerial decision-making by focusing on the volume flexibility
system for smooth production runs. The mathematical formulation of the
developed inventory system tries to optimize the inventory cost function
under a realistic scenario. A solution procedure has been illustrated and
assisted with a numerical example. Later, a validation test is also
performed to check the robustness of the proposed mathematical model. The
findings of the study will support policymakers, strategists, and firms to
implement flexible inventory systems under realistic conditions.
Psicologia islâmica
Authors: Omais Sálua , Antônio dos Santos Manoel
Published: December 2022

A busca por novos paradigmas e epistemologias que atendam as demandas dos mais diversos grupos étnico-culturais tem sido uma tendência crescente no campo da psicologia. O uso de teorias universalizantes hegemônicas que por tanto tempo dominaram a Ciência, desconsiderando a influência da religião e da espiritualidade nas cognições, emoções e comportamentos do indivíduo, cria a necessidade de novas propostas epistemológicas a fim de abarcar tais singularidades. A inclusão da religiosidade/espiritualidade (R/E) nas práticas e intervenções terapêuticas tem sido encorajada pelos resultados positivos descritos pela literatura, tanto na esfera física quanto psíquica, o que inspira a necessidade de ampliação contínua do conhecimento neste campo. Esse cenário abre espaço para a conjugação de diversos saberes com a ciência psicológica em uma perspectiva multidisciplinar, entre os quais tem se destacado a psicologia islâmica. Este artigo é uma revisão de literatura que tem como objetivo apresentar as bases, marcos e elementos que contribuíram para a construção de alguns dos modelos teóricos da psicologia islâmica, analisando os avanços e desafios enfrentados na constituição deste campo de estudo. Diante disso, conclui-se que, apesar de o saber religioso não oferecer respostas para todas as indagações da ciência psicológica, ele pode agregar informações que ajudem na compreensão da psiquê humana e do estudo da alma. Embora seja um campo pouco explorado na ciência atual, a psicologia islâmica é uma epistemologia que possui suas raízes em saberes religiosos e filosóficos islâmicos milenares, tendo como proposta principal a construção de uma abordagem holística que integre as dimensões física, mental e espiritual.

Para isso, realizou-se um levantamento de dados no Diretório de Grupos de Pesquisa, com foco nos grupos vinculados a instituições da ALB. Como resultados, encontrou-se que a maior parte dos Grupos de Pesquisa com esta temática estão localizados no Estado do Pará, e que há um certo isolamento dos pesquisadores em seus grupos. Outrossim, observou-se a ausência na formação de novos grupos após o ano de 2017, sendo importante incentivar a criação destes ambientes para uma ampliação das discussões dessa temática.

Published: December 2022

The article discusses experimental studies of the strength characteristics of high-strength concrete and steel fiber reinforced concrete from highly mobile concrete and steel fiber reinforced concrete mixtures. There have been obtained experimental dependences of prism and cube strength before and after alternate cyclic freezing and thawing. Calculation formulas are proposed that demonstrate the relationship between cube and prism strength in compression and tension. Calculation diagrams of steel fiber reinforced concrete under compression and tension of experimental prism samples are formed.

Endodontic microsurgery was introduced in the ‘90s and has significantly increased the success rate of apical surgical intervention the last few decades. Utilizing the dental operating microscope, ultrasonic tips for root end preparation and biocompatible root end filling materials, predictably manages the apical pathology preserving the buccal cortical plate. The bone window technique for buccal approach to the apical area involves the use of piezoelectric unit to prepare and elevate a buccal cortical bony window and the reposition of the bone after the apical root end filling is completed. Two cases are reported in this article, highlighting the importance of endodontic microsurgery and buccal bone window technique in addressing apical pathology in a minimally invasive way, preserving the hard tissues and the tooth structure. Cases were reevaluated clinically and radiographically after a period of 3 months up to 36 months.
Elements of the Transformation of Preschool Curriculum and Educational Practices
Authors: Slunjski Edita , Lančić Marina
Published: December 2022

The development of a curriculum poses a challenge for theoreticians, practitioners and educational policy makers. The official curriculum of a country represents the guidelines that should serve as the basis on which practices are developed in educational institutions. However, every institution modifies and applies the curriculum differently. The level of a practitioner’s professional development, as well as the culture of the educational institution in question profoundly influence the manner in which the curriculum is evolving in a particular educational institution. For that reason, it is especially important to facilitate access to systematic and high-quality professional development for preschool teachers, so that they are capable of developing the curriculum in line with the challenges of our time and contemporary scientific findings on early childhood education and care. The practice of many preschool teachers in Croatia reflects an outdated understanding of educational work involving children, and the official curriculum does not have much of an impact on that fact. Despite the fact that the practices of individual preschool teachers, even within the same institution, can differ significantly, there are certain shared traditionalisms that represent a burden for practice in Croatian preschools, and that are not easily removed. In order to gradually remove them, i.e., replace them with more contemporary methods of educating children, it is necessary to first become aware of them, as it is precisely the lack of awareness that such traditionalisms exist that causes them to remain a part of the practice.
Orthodox Clergy About the Bolshevik and Nazi Types of Socialism (1930–1940s)
Authors: Ivan V. Petrov
Published: December 2022

The article considers and analyzes the perception of the Bolshevik and Nazi regimes by the Orthodox clergy, their policy towards the Church, as well as the essence of anti-Christian doctrines. The starting point of the study is 1927 and the release of the infamous “declaration of loyalty” by Metropolitan Sergius (Stragorodsky). In addition to further discussion about the possibility of recognizing Soviet power and solidarity with its policy of the Orthodox clergy, the article raises the question of the limits of support for political regimes that aim to combat religion. The period of the Great Patriotic War is subjected to special consideration, when many bishops and priests revised their views on the communist system in the Soviet Union, both due to the political situation and due to the transformation of their own opinion. Also, a polar view of the clergy on German National Socialism arose, depended on being on one side or the other of the front.
Alexander Herzen and Natalia Zakharina: an Episode from 1838. Love Fever, Christianity and Early Socialism
Authors: Andrey A. Teslya
Published: December 2022

Alexander Herzen has been the subject of an immeasurable number of biographical works as well as studies in the history of ideas, political philosophy, the history of philosophy, and a number of other disciplines. At the same time, we cannot say that the study of Herzen’s ideas has been exhausted, and while our knowledge of his biography is unlikely to expand significantly, the range of sources published to date is if not exhausted then at least close to it, a detailed study of Herzen within the framework of intellectual history and the history of political thought remains a highly relevant task. This is primarily due to the fact that, as the «big ideologies» of the 19th century recede into the past, it is time to undertake an in-depth analysis not only of the processes of forming their specific versions and debates within the framework of big ideological structures, but also to pay attention to theoretical transfers from one ideological framework to another and, far more important, to consider not from retrospect, knowledge about what these or those ideological and ideological structures will become in their development, but in synchronicity. This arrangement of the cognitive gaze is also close to Herzen’s mature philosophy, with its focus on alternatives (real ones), a history that develops as improvisation-not free of logic, but not subject to strict necessity either. In this article we focus our attention on a small episode of Herzen’s life - his stay in Vladimir in 1838 during several winter and spring months, between his arrival from Vyatka (after granting him relief from exile) and up to his marriage with his cousin Natalia Zakharina. In this small interval of time Herzen devotes almost entirely his time, free from non-burdensome service, to reflections on his past life, autobiographical experiences and love correspondence with his bride (with the latter including numerous material on the first two subjects). This focus on the intimate in the context of a mature romantic and socialist outlook turns out to be both a development of Natalia-Alexander’s «personal myth» and a new, in relation to the years 1834-1837, reflection on possibilities and ways for the self in the aspect of universal, all-important action/behavior/existence.
“Socialism” of the Priest Grigory Petrov in the View of Maxim Gorky
Authors: Konstantin A. Kostromin
Published: December 2022

A well-known pre-revolutionary writer and orator, priest Grigory Petrov, was perceived by some contemporaries as a socialist. Maxim Gorky, who himself gravitated towards socialist views, was one of the first to call him a socialist. However, over time, Gorky’s views on socialism and his attitude towards Petrov changed. The article traces the evolution of Gorky’s views on socialism in the context of his “god-seeking”, as well as relations with the Bolsheviks, shows the evolution of Petrov’s relationship with the writing community. An analysis of the content of Petrov’s book “The Gospel as the Basis of Life” showed that it is difficult to unambiguously consider him a socialist. This was reflected in Gorky’s attitude towards Petrov. The history of their relationship is reconstructed based on the analysis of the preserved and published correspondence between Gorky and relatives and friends
The Topic of Socialism in the Emigrant Journalistic Works by V.V. Shulgin
Authors: Anton A. Chemakin
Published: December 2022

Readers are invited to the articles, published by politician and journalist V.V. Shulgin in emigrant newspapers and united by the theme of socialism. Issued in the 1920s in Russian emigrant press, they have never been reprinted since then, and some of them are completely absent from the collections of Russian archives and libraries. In these articles, V.V. Shulgin acts not only as an opponent of socialism in general and Bolshevism in particular, but also pays attention to a critical examination of Slavophile theories about the originality and usefulness of the peasant community, the existence of which the author considers one of the main reasons of the collapse of “old” Russia
