Inventory Policy for Retail Stores: A Multi-Item EOQ Model Considering Permissible Delay in Payment and Limited Warehouse Capacity
Authors: Silitonga Roland Y. H. , Sembiring Ester E. L. Br
Published: June 2022

The retail industry such as minimarkets has many products consisting of several types of products that have expiration dates. Their warehouses have limited capacity, making it difficult to make decision about optimum inventory. Most of the suppliers will give permissible delay in payment, that can be used to increase income potential through earned by considering the risk of fines imposed if payments are exceeded and help companies raise capital before generating sales. These three factors must be considered when developing the inventory model. The purpose of this study is to develop a multi-item inventory model by considering perishable or damaged products, permissible delay in payment in limited warehouse. Model development is carried out in 2 stages. The first stage was the development of a multi-item EOQ model by considering product defects and permissible delay in payment. The second stage model is by adding a capacity constraint factor to the model. The results obtained are getting the optimal order quantity by considering the number of product types, product damage factors, late payments in limited warehouses, the best ordering policy can be found, and it is known that the total inventory costs to changes in parameters are good and sensitive to changes in percentage, interest percentage, payment allowances, and warehouse capacity through sensitivity tests.
Luchas de representación: Prácticas, procesos y sentidos audiovisuales colectivos en el suroccidente colombiano

“En la película La última gallina en el solar hay un personaje, El Mosca, que habla como el propio actor; o sea, él en la vida real habla así y en la película dice: '¡Es una heriencia que me dejó mi abuela!'. Entonces alguien le dijo: “¡No, no, se dice herencia!”. Y yo le dije: 'No, no, sigamos grabando que está bien'. También pasó cuando ese actor dice yama, que se dice en realidad yema, la del huevo. Lo mismo cuando él dice comprobancia. Allí dijeron: '¡No, lo que pasa es que él quiso decir prueba!'. Y entonces yo les dije: '¡Pero me estás hablando de un sinónimo y todo el mundo va a entender lo que él quiso decir!'. Para uno entender no necesita siempre que le digan la palabra correcta y la gente entiende lo que uno quiere mostrar. Por eso es bueno no callar a las personas que tienen su voz; porque es importante uno conocer la expresión cultural de esas personas. Ahí es donde me parece que mostrar la forma de hablar de El Mosca es como una forma de mostrar que la televisión siempre quiere una perfección y ahí se oculta la realidad de las personas. La televisión tapa muchas cosas que la realidad nos puede mostrar” [Gufilms].
Legal worldview as an attribute and component of legal consciousness
Authors: Zozulia Aleksandr
Published: June 2022

The object of the study is legal awareness as a phenomenon of the sphere of positive law. The subject of the research is the legal worldview as a legal category and a phenomenon of legal reality. The author examines in detail the terminological aspect, analyzes various approaches and formulates an integrative definition of the legal worldview. Special attention is paid to the modern determinants of the formation of a legal worldview and the definition of key criteria for a socially acceptable legal worldview. The theoretical basis of the research is post-non-classical concepts of legal understanding, considering law as a means of social communication. The system, axiological and formal legal methods were used. The purpose of the study is to develop directions for the formation of a socially acceptable legal worldview.The approach applied by the author to the study of legal consciousness through the prism of the legal worldview, taking into account the determinants of legal reality, ensures the novelty of the research results. The author, in line with a broad understanding of the legal worldview, suggests considering it as a dominant value-normative component of legal consciousness, examines the factors of state-legal reality that influence public legal consciousness, among which he highlights the diversification of modern legal understanding, crisis phenomena in the field of positive law, the actualization of self-regulation in the legal sphere. On this basis, the key features of a socially acceptable legal worldview are formulated and a conclusion is made about the need to modernize the legal component of educational programs at various levels.
Dual citizenship in the context of the interaction of international and national public law
Authors: Proniakina Svetlana
Published: June 2022

The subject of the study is international legal conventions and agreements concluded in the XX-XXI centuries on issues of dual citizenship. The methodological basis of the research consists of the following methods of cognition: system legal analysis, comparative legal and formal legal analysis. The purpose of the work is to compare international legal norms that consolidate the legal status of persons with dual citizenship. The article examines the issues of military duty and tax payment by bipatrides, as well as the constitutional and legal regulation of legal relations related to citizenship, analyzes the institution of dual citizenship in the context of the protection of state sovereignty. The author considers bilateral international legal agreements concluded on issues of dual citizenship. The author concludes that the adopted international acts are mainly aimed at reducing the occurrence of dual citizenship, which indicates the unwillingness of countries to openly recognize this legal institution. The scientific novelty of the study lies in the fact that the author proposes the inclusion in international legal acts on the avoidance of double taxation of additional criteria for determining the status of tax residence of bipatrids. In order to develop international cooperation with the Republic of Belarus, the author proposes the adoption of a single Union normative legal act in the field of citizenship, which enshrines the rights and obligations of citizens of the Union State and establishes that citizens of the Union State are not persons with dual citizenship.

Zeno’s Dichotomy and the Paradox of Logical Causality
Authors:   Tomsk Scientific Center of the Siberian Branch of the Russian Academy of Sciences, Borisov Evgeny ,   Tomsk State University
Published: June 2022

A number of versions of Zeno’s ‘Dichotomy’ is being discussed in literature. Some of them are versions of a paradox that can be called ‘the paradox of logical causality’. It can be traced back to Benardete; in recent decades it has been discussed by Priest, Yablo, Hawthorne, Uzquiano, Shackel, Caie, and others. Unlike the original ‘Dichotomy’, the paradox of logical causality is an open problem for it has no generally accepted solution. In the paper, I examine the solution to the paradox proposed by Hawthorne and argue that it has an essential flaw caused by Hawthorne’s rejection of what he calls ‘the Change Principle’. I also compare the paradox and Zeno’s ‘Dichotomy’ and specify features shared by them, and features distinguishing the paradox. Their shared features are using infinite open series and reasoning from logical premises to physical conclusions. What distinguishes the new paradox is presupposing motion, and applying Zeno’s series to phenomena of physical interaction.

Philosophy and Religious Politics in Damascius’ “Philosophical History”
Authors:   Novosibirsk State University, Afonasin Eugene ,   Institute of Philosophy and Law SB RAS
Published: June 2022

In the paper, I consider some aspects of religious politics in late antiquity on the basis of select fragments from Damascius’ “Philosophical History,” translated into Russian for the first time. I also observe that the archeological finds, often better than the biased literary evidences, show both the different strategies of interaction between the adherents of pagan cults and official Christianity in late antiquity and, more importantly, the non-linearity of the paths by which Christians advanced towards their goal, without ever reaching it. We see that the church authorities often permitted the total destruction of pagan sanctuaries, as happened in 392 with the Serapeum, by initiating the full-scale persecution of pagans and their physical elimination, as Damascus testifies in many sections of his history. On the contrary, in some cases they sought only to "neutralize" the pagan cult, depicting crosses on statues and using ancient temples as churches and, accordingly, to attract the pagan intellectual elite to their side. All in all, this material allows us to take a more comprehensive view of history, reconstructing a complex cultural context.

Introduction We studied the duration of adaptation to new complete dentures (CD) and changes for 5 years based on patients’ self-reported outcomes. Methodology Sixty fully edentulous patients who received new CDs and wore them for 5 years were included. A questionnaire (answers 0-10 VAS) related to self-perceived speech, chewing function, comfort of denture wearing, denture retention, and orofacial esthetics was completed on the 1st, 3rd, 8th, 15th, and 30th day after new CD delivery, and after 1, 3, and 5 years of denture wearing. Results Self-perceived speech reached the highest scores on the 30th day; females and previous removable denture (RD) wearers adapted faster during the first days. Chewing reached the highest scores on the 30th day, remained unchanged over the 1st year, and decreased significantly afterwards; females gave higher scores during the first 15 days and previous RD wearers from the 3rd till the 30th day. A comfort of denture wearing first slightly decreased, but soon increased, reaching the highest values the 30th day, remained unchanged after one year, then decreased gradually, with no significant difference between gender and previous RD experience. Retention scores decreased after 3 and 5 years, without difference between gender and previous RD experience. Orofacial esthetics scores decreased substantially after 3 years with no effect of gender and previous experience (p>0.05). Conclusion The highest scores were obtained for orofacial esthetics and speech, the lowest for chewing function. Participants needed 30 days to adapt to new CDs. The adaptation lasted one year and decreased significantly the 3rd and the 5th year
Management of single tooth gingival recession using free gingival grafting followed by coronally advanced flap with cross-linked collagen matrix: A case report
Authors: Tokpam Sarda , Bains Vivek Kumar , Chandra Chetan , Srivastava Ruchi
Published: June 2022

Gingival recession is the exposure of root surfaces due to apical migration of the gingival margins beyond the cementoenamel junction and is considered as one of the most common esthetic concerns associated with periodontal tissues. Insufficient gingival thickness and lack of adequate width of attached gingiva are considered to be the most common reason for progressive gingival recession. This case report presented the management of gingival recession in the lower anterior tooth using two-stage recession coverage technique. In the first stage, free gingival grafting was performed which was followed by coronally advanced flap in combination with cross-linked collagen matrix (Fibro-Gide, Geistlich Biomaterials, Switzerland) for recession coverage and enhancement of gingival thickness. Three-month follow-up of the case reported significant enhancement in clinical parameters with improvement in patient’s esthetic demand.
Diagnostic utility of conventional and liquid-based cytology in the management of thyroid lesions; an institutional experience
Authors: Sharma Rohit , Zaheer Sufian , Ahluwalia Charanjeet
Published: June 2022

Objectives:

Liquid-based cytology (LBC) is becoming a useful method in evaluating both gynecological and nongynecological preparations. Many studies have been conducted these days to see the quality of LBC in diagnosing thyroid lesions and its role is yet to be standardized. This study has been done to pick the cytomorphological features of thyroid lesions on LBC and to compare them with the conventional cytology of these lesions.The objective of the study is to evaluate the efficacy of thyroid fine-needle aspiration cytology processed by LBC as compared to conventional smears.

Material and Methods:

A prospective study has been done on 53 cases of thyroid lesions using standard conventional and LBC techniques.

Results:

In most of the cases, the cytological features are similar in conventional cytology smears and LBC, but the colloid film and the lymphocytic component show a clear picture on direct smears, whereas nuclear and cytoplasmic details are better evaluated in LBC slides. The preservative solution used in LBC could be efficiently used for the application of immunocytochemical and molecular techniques.

Conclusion:

LBC does not represent as a valid alternative to conventional cytology but it can be considered as a diagnostic utility process especially due to the possibility of applying additional techniques which enhance the efficacy of the cytological diagnosis of thyroid lesions.

Qu’est-ce qui lie les chaînes de vlog basées sur des couples ? Cette analyse se fait sous l’angle de la médiation et de la médiatisation, c’est-à-dire en s’intéressant au processus de communication qui dépend autant du dispositif technique à disposition, à savoir YouTube, qu’aux normes propres à la communauté en question, les couplesvlogueurs. D'abord, les chaînes sont soumises à une analyse formelle, puis les vidéos sont analysées dans leur contenu. Trois catégories de vidéos ressortent : "quotidien sensationnalisé", "accès à l'intime" et "révélations". Bien que les sujets diffèrent, les aspects présentatifs des chaînes et les stratégies de mise en scène sont quasiment similaires, d’où la conclusion que les couples-vlogueurs sont membres d'une même communauté, car ils ont une même manière de médiatiser.
In situ Time-Resolved Spectroelectrochemistry Reveals Limitations of Biohybrid Photoelectrode Performance
Authors: Nawrocki Wojciech J. , Jones Michael R. , Frese Raoul N. , Croce Roberta , Friebe Vincent M.
Published: June 2022

Photosynthetic reaction centres catalyse the majority of solar energy conversion on Earth. These pigment proteins achieve this goal with a near-unity quantum efficiency, transducing the energy of almost every absorbed photon into that of a charge separated state. Capturing the high efficiency of these natural proteins with man-made electrodes is the goal of biohybrid technologies such as biophotovoltaics, biofuel cells and biosensors. However, the removal of reaction centres from their natural cellular environment and their integration into an abiotic biohybrid architecture invariably introduces loss channels that compromise energy conversion efficiency. Here, we developed the combined use of spectroscopy and analytical electrochemistry to identify electron transfer bottlenecks, back-reactions and short-circuits that affect the performance of a bacterial reaction centre-based biophotoelectrode. We determined that the system was over 90% efficient under low intensity light but dropped to ~10% efficiency under intense continuous illumination. Limitations and loss processes included bottlenecks in electron transfer that rendered 62% of reaction centres inactive, as well as a short-circuiting of 73% of the photochemical product from active reaction centres. These findings will help shape rational design strategies for improving the performance of biohybrid devices and may be more broadly applied to other donor-acceptor type photocatalysts.
Reductive Dimerization of Styrenes to 1,4-Organodilithiums Enabled by Flow Microreactors
Authors: Jiang Yiyuan , Yorimitsu Hideki
Published: June 2022

Reduction of styrenes with lithium arenide in a flow microreactor leads to the instantaneous generation of the radical anion of styrenes and subsequent dimerization by fast mixing to yield the corresponding 1,4-dilithium species. The efficiency and selectivity of this reductive dimerization are low in a batch reactor. A series of styrenes undergo the dimerization and the resulting 1,4-dilithium species are trapped with various electrophiles. Trapping with divalent electrophiles such as dichlorosilanes affords precursors for useful yet less accessible cyclic structures such as siloles. Single electron reduction of unsaturated compounds in flow microreactors has thus proved to be a powerful protocol in organic synthesis.
Mechanistic Roles of Metal- and Ligand-Protonated Species in Hydrogen Evolution with [Cp*Rh] Complexes

Published: June 2022

Protonation reactions involving organometallic complexes are ubiquitous in redox chemistry and often result in the generation of reactive metal hydrides. However, some organometallic species supported by η5-pentamethylcyclopentadienyl (Cp*) ligands have recently been shown to undergo ligand-centered protonation by direct proton transfer from acids or tautomerization of metal hydrides, resulting in the generation of complexes bearing the uncommon η4-cyclopentadiene (Cp*H) ligand. Here, time-resolved pulse radiolysis (PR) and stopped-flow spectroscopic studies have been applied to examine the kinetics and atomistic details involved in the elementary electron- and proton-transfer steps leading to complexes ligated by Cp*H, using Cp*Rh(bpy) as a molecular model (where bpy is 2,2′-bipyridyl). Stopped-flow measurements coupled with infrared and UV-visible detection reveal that the sole product of initial protonation of Cp*Rh(bpy) is [Cp*Rh(H)(bpy)]+, an elusive hydride complex that has spectroscopically and kinetically characterized here for the first time. Tautomerization of the hydride leads to the clean formation of [(Cp*H)Rh(bpy)]+. Variable-temperature and isotopic labeling experiments further confirm this assignment, providing experimental activation parameters and mechanistic insight into metal-mediated hydride-to-proton tautomerism. Spectroscopic monitoring of the second proton transfer event reveals both the hydride and related Cp*H complex can be involved in further reactivity, showing that [(Cp*H)Rh] is not necessarily an off-cycle intermediate, but, instead, depending on the strength of the acid used to drive catalysis, an active participant in hydrogen evolution. Identification of the mechanistic roles of the protonated intermediates in the catalysis studied here will inform design of new catalytic systems supported by non-innocent cyclopentadienyl-type ligands.
Combining Iminium and Supramolecular Catalysis for the [4 + 2] Cycloaddition of E-Cinnamaldehydes
Authors: Shrestha Kendra , Hilyard Michael , Alahakoon Indunil , Young Michael
Published: June 2022

Herein we describe a method for combining supramolecular catalysis with imininum-based organocatalysis in the Diels–Alder cycloaddition reaction. Notably, both cage and L-proline are required for the reaction to occur, implying that encap-sulation of the substrates and co-catalyst are necessary for the reaction to occur. We explore the substrate scope for a va-riety of E-cinnamaldehydes and dienes. Finally, we probe the supramolecular assembly processes responsible for the observed catalysis using NMR spectroscopic methods, determining that the reaction is negative order in the cinnamalde-hyde substrate and experiences product inhibition.
The microkinetics of ammonia synthesis: the effect of surface coverage on apparent activation energy and reaction order
Authors: Morimoto Ryusei , Ogawa Takaya , Ishihara Keiichi
Published: June 2022

We investigated the coverage effect on the experimental results using Ru and Ru+K for ammonia synthesis at 0.1 MPa and 380~460℃. Especially for Ru+K, the reaction order changed significantly with temperature, and the rate-limiting step was also affected by temperature. The apparent activation energy decreased as the gas flow rate decreased, even when the total pressure was the same. We showed through experimental techniques that even relatively small changes in experimental conditions on a laboratory scale can change the coverage and have a non-negligible effect on the reaction order and apparent activation energy.

Published: June 2022

Supported gold nanoparticles play a fundamental role in modern heterogeneous catalysis. However, controlling their fine dispersion remains a challenge, in particular when using silica supports. Here, we report a simple one-pot aerosol route to Au-SiO2 catalysts featuring small gold nanoparticles and calibrated mesoporous texture. To achieve such result, we rely on the strong interactions between gold and the thiol function of a mercapto-silane. We show that the addition of this gold-stabilizer during synthesis enhances the stability of the gold precursor and is the key to control the formation of small gold nanoparticles in the one-pot synthesis. After calcination, the catalyst displays advantageous textural properties (SSA = 440 m².g-1; Vp = 0.5 cm³.g-1; Dp = 5 nm) with small gold nanoparticles (3.7 nm, compared to 13.7 nm without the stabilizer). The dispersion of gold in the material reaches 21 % (compared to 3 % without the stabilizer). The selective oxidation of glycerol to dihydroxyacetone was employed as a test reaction, of importance in the context of sustainable chemistry. We show that the highly dispersed catalyst obtained via gold stabilization outcompetes benchmark catalysts, reaching a glycerol conversion of 59 % after 8 hours (vs. 5 % without stabilization).

Polycrystalline diamond has the potential to improve the osseointegration of orthopaedic implants compared to conventional materials such as titanium. However, despite the excellent biocompatibility and superior mechanical properties, the major challenge of using diamond for implants, such as those used for hip arthroplasty, is the limitations of microwave plasma chemical vapor deposition (CVD) techniques to synthesize diamond on complex-shaped objects. Here, for the first time we demonstrate diamond growth on titanium acetabular shells using surface wave plasma CVD method. Polycrystalline diamond coatings were synthesized at low temperatures (~400 °C) on three types of acetabular shells with different surface structure and porosity. We achieved the growth of diamond on highly porous surfaces designed to mimic the structure of the trabecular bone and improve osseointegration. Biocompatibility was investigated on nanocrystalline diamond (NCD) and ultrananocrystalline diamond (UNCD) coatings terminated either with hydrogen or oxygen. To understand the role of diamond surface topology and chemistry in the attachment and proliferation of mammalian cells, we investigated the adsorption of extracellular matrix (ECM) proteins, and monitored the metabolic activity of fibroblasts, osteoblasts, and bone marrow-derived mesenchymal stem cells (MSCs). The interaction of bovine serum albumin (BSA) and Type I collagen with the diamond surfaces was investigated by confocal fluorescence lifetime imaging microscopy (FLIM). We found that the proliferation of osteogenic cells was better on hydrogen terminated UNCD than on the oxygen terminated counterpart. These findings correlated with the behaviour of collagen on diamond substrates observed by FLIM. Hydrogen terminated UNCD provided better adhesion and proliferation of osteogenic cells, compared to titanium, while growth of fibroblasts was poorest on hydrogen terminated NCD and MSCs behaved similarly on all tested surfaces. These results open new opportunities for application of diamond coatings on orthopaedic implants.

Published: June 2022

Asthma is a chronic airway inflammatory disease, characterized by reversible airway obstruction and airway hyperresponsiveness. It affects 1-18% of population in different countries and approximately 5–10% of the overall asthma population has severe asthma. Systemic glucocorticoids still represent a significant burden due to treatment of asthma exacerbations and severe forms of asthma. Monoclonal antibodies are powerful anti-inflammatory agents with glucocorticoid-sparing properties. With the increasing use of biologics, tapering and cessation of maintenance systemic glucocorticoids have become much more common. Personalized approach to tapering and careful assessment for adrenal insufficiency in all patients are recommended by the experts.

Authors: J Kurukulaaratchy Ramesh , Eames Chellan
Published: June 2022

Difficult-to-treat (or difficult) asthma presents a challenging multidimensional model of chronic disease that imposes a significant burden at both individual patient and wider societal levels. Within that model of disease there is increasing understanding of the diverse range of asthma phenotypes that might be encountered. There is also the growing realisation that these do not occur in isolation but exist within a wider multimorbidity disease framework. Identifying these other treatable traits that exist within the setting of difficult asthma has shown capability to improve patient outcomes. In that context, application of structured approaches to patient assessment have shown good efficacy, both at more general as well as specialist care levels. So too have multidisciplinary team approaches to difficult asthma care. The combined roles of the Asthma Specialist Physician, Asthma Nurse Specialist, Asthma Pharmacist, Speech & Language Therapist and Asthma Dietitian in that regard are evolving rapidly. In this chapter we review the multimorbidity model of difficult asthma and how best to approach that via multi-disciplinary team working approaches when undertaking specialist management of adult difficult asthma in clinical practice.
Topics in Spherically Symmetric Spacetimes
Authors:   , Jowsey Aden
Published: June 2022

Throughout this thesis, we explore mathematical and physical ideas pertaining to much wider theoretical understandings through the context of convenient stellar models described by spherically symmetric perfect fluid stars. These relativistic models allow for an ease of computation and analysis in more physically interesting situations.

Of direct investigation in this thesis is the construction and physical viability of multi-layered stellar models, that is stellar objects with controlled discontinuities in their equation of state. Here, the conditions for junction-free thin-shell intermediary boundary layers are calculated in general through Israel–Lanczos–Sen formalism, then applied to ideal metrics to produce and discuss tractable examples.

Additionally, we investigate and produce counter-examples to modern theories involving maximal quantities, namely maximum power, using intuitive definitions. These analyses include evaluations of physical reasonability, such as through the enforcement of energy conditions across a given spacetime. Here, we aim to voice arguments for definitional caution, regarding the scope of maximal theories. The philosophical nature of such theories remains outside of the scope and consideration of this thesis.

Overall, in this thesis is presented a series of mathematical and physical analyses through the well-understood medium of isotropic perfect fluids, within the framework of general relativity. Our approach is designed to create extension agnostic results, that can be developed and extrapolated to higher complexities as one desires.

Published: June 2022

Dieng Wetan Village is one of the areas in Wonosobo Regency that has tourism potential. In publicizing their tourism potential, local youth released an Instagram account @desadieng. However, the publication of tourism through this account is a problem. This is due to several factors. First, the lack of human resources (HR) from the youth organizations of Dieng Wetan Village as managers. Second, the need to strengthen HR skills in terms of content writing, photo and video production as a medium for publication of regional tourism potential. Therefore, it is necessary to carry out a training in the production of written and photo content for youth members of Dieng Wetan Village as the manager of the official @desadieng account as a form of publication of regional tourism potential. The training was carried out in four stages, including situation analysis, planning, implementation, and evaluation. The training program which was held for two days began with the provision of materials, discussions, field practices, and evaluations. As a result, participants were able to create promotional content for the tourism potential of Dieng Wetan Village through Instagram social media channels. In the future, participants need to sharpen their sensitivity to local wisdom issues that can enrich publication materials. In addition, public awareness also needs to be formed so that they can independently manage the @desadieng account as the official and consistent official account of Dieng Wetan Village tourism publications.
PERAMALAN DENGAN METODE SARIMA PADA DATA INFLASI DAN IDENTIFIKASI TIPE OUTLIER (Studi Kasus: Data Inflasi Indonesia Tahun 2008-2014)
Authors: Fadliani Iin , Purnamasari Ika , Wasono Wasono
Published: June 2022

Inflation is defined as rising prices of goods in general and continuously. The effect of inflation on the economy can cause the currency to decline, resulting in the country's economic power becoming weak. Time series data is data arranged in order of time or data collected over time. Changes in the inflation rate tend to make inflation data unstable and affect the forecasting process in the time series data. The method used in this study is the seasonal autoregressive integrated moving (SARIMA) method to predict the time series in one or two periods ahead. This study also used outlier identifiers on models that still have outlier tendencies in residuals. The forecasting results of the SARIMA method become inaccurate when residual data contains outliers. The presence of outlier data in residual data results in residuals is not a normal distribution. The method used obtained the best model results, namely the SARIMA model (0,1,1) (0,1,1)12 with inflation forecast value for January to May 2015 is in the range of 5-6 %. On SARIMA models (0,1,1) (1,1,1)12 and SARIMA models (1,1,0) (2,1,0)12 outliers are detected in residual are Additive Outlier (AO) and Temporary Change (TC) type.

Authors: DIMITROVA-GIRGITSOVA Ani
Published: June 2022

Objectives: The question that the article attempts to answer is whether and how the opportunities for meaningful work could be positioned as a competitive advantage in job advertisements. A specific focus is the software development job market in Bulgaria. Material and methods. Content analysis was applied to a sample of 60 job advertisements using the keywords “software engineer” and “software developer”. All selected job advertisements included a part describing what the company offers to its potential new hires. This specific part of the job advertisement was analyzed through manual coding of phrases. The coding was drawn from the Meaningful Work Framework model developed by Lips-Wiersma and Morris (2009) and Lips-Wiersma and Wright (2012), including “Unity with Others”, “Developing and Becoming Self”, “Expressing Full Potential”, “Service to Others”. Results. The majority (64%) of the phrases related to meaningful work could be linked to “Expressing Full Potential”. “Unity to Others” could be identified as a theme in 32% of the phrases related to meaningful work. “Service to Others” was found in 3% of the phrases. “Developing and Becoming Self” was not identified as a theme. Conclusion. Even though elements of the concept of meaningful work could be identified in the analyzed job advertisements, there is a prevalence of opportunities related to “Expressing Full Potential”. Such disbalance could be attributed to the job advertisements’ specifics as a medium to promote opportunities for new jobs. Keywords: meaningful work, job advertisements, software developer.

Social Media for Teaching and Learning: A Technology Acceptance Model Analysis of Preservice Teachers’ Perceptions During the COVID-19 Pandemic
Authors: Mangundu John
Published: June 2022

The Covid-19 pandemic has resulted in the adoption of lockdowns, social distancing, and quarantines as measures to contain the spread of the coronavirus, forcing education spaces in both developed and developing economies to suddenly shift towards adoption of emergency online teaching and learning. However, developing economies were lagging in the migration to online teaching and learning strategies due to incapacity and lack of resources such as formal learning management systems (LMS) that support the migration. Social media use has been identified as an alternative given the sharp rise in social media (SM) presence and activities around the world by individuals of different age, regardless of economic status, during the lockdowns. A few studies have been conducted on the perceptions of SM use by preservice teachers in a developing country context. Through the technology acceptance model (TAM), this study applied a mixed methods approach to examine perceptions of preservice teachers on SM use in teaching during the practice periods. Results revealed that preservice teachers perceived SM platforms as mainly for social purposes rather than educational purposes, despite their high usage of WhatsApp and YouTube. The study recommends initiatives to change preservice teachers’ mindset as part of teachers’ professional development to get them to appreciate the usefulness of SM platforms in education contexts.

Gamification is a learning approach that transfers the power of games to the education context, with the purpose of improving the performance of students in the classroom. The present study aimed to analyze scientific activity related to gamification in the context of higher education by using a bibliometric and bibliographic approach and the Scopus database. A bibliometric study was applied with the help of VOSviewer and RStudio software, and the authors managed to identify 287 documents published between 2012 and 2022. The results were classified according to the most influential published documents, keyword co-occurrence network, trend topics, collaboration maps between countries and authors, scientific production by countries, and geographical scientific gaps. The findings show a large geographical scientific gap for the African continent, in particular. This research provides an overview of publications on the topic of gamification in the university environment.

Authors: Mohd Zhaffar Nursafra , Rashed Zetty Nurzuliana
Published: June 2022

Although there is a growing interest in the culture of thinking in education, detailed information about classroom interaction that can incorporate thinking culture is lacking, particularly in the Malaysian context. Additionally, past studies do not focus on Islamic education. This study aimed to explore the feedback of excellent teachers in classroom interactions to incorporate a thinking culture. A qualitative case study approach was adopted on six excellent teachers (ETS) in Islamic Education using purposive sampling. Data were collected via teaching observation, semi-structured interviews, and document analysis. Thematic analysis revealed five themes that represented ETs’ feedback in classroom interactions to enhance thinking culture: give praise, give reprimand and criticism, stimulate information seeking, evaluate information, and ask for clarification. This study added value to the description of teachers’ feedback to create a thinking culture, especially in Islamic Education classrooms in Malaysia. The findings indicated that teachers need to increase open feedback, be willing to listen to students’ views, use praise and criticism selectively, and be a trustee of students for a democratic classroom to be realized. This study is expected to strengthen the effectiveness of teaching that incorporates a thinking culture.
