The article considers the determinants of the strategy of tourism business development in the regional economic and social destination, which are implemented according to the criteria for assessing the quality of components of the tourist flows. The purpose of the study was to implement these determinants and to develop the mechanism of regulation of the development of tourist business in regional economic and social destination of market type. An approach to the concept of a tourist product as a set of properties that determine its usefulness and form value and attractiveness for tourists was used allowing the reliability of its assessment as a commodity with the definition of promising areas of change in consumer behavior in regional blocs and their interaction with neighboring territories. The multi-attributive model of a tourist product in a regional economic and social destination was used. During the study, the necessity to form an optimal price mechanism for tourism products, which will give market regulators a targeted and less costly self-development of business structures in the tourism sector was found. The development of tourism business can help to create affordable conditions for continuous improvement of the business climate and competition. It was proved that the existing tools for assessing the tourism business are the levers of indirect influence on the state economy.

Saharan tourism in Algeria is promising and can give a boost to the country’s tourism and the economic sector. The aim of this study is to measure the tourist appeal of Biskra through its natural and cultural assets. We will try to identify its potential and constraints in order to promote local tourism while taking into account the specificities of our territory. This study will focus on the Biskra province, which is one of the Saharan Algerian cities. It is located in the loop of oases, connecting the north and the south of the country. It is famous for its palm trees, dates (Deglet Nour) and its traditional architecture. Within the framework of spatial planning and tourism development our research theme will focus on the enhancement of local assets in order to promote the tourism sector so that it is equitable and sustainable while respecting moral and cultural integrity of the region. To do so, we opted for a theoretical and analytical approach by consulting a set of bibliographic references, interviewing local officials and conducting field visits. Driven by SWOT analysis (Strengths – Weaknesses – Opportunities – Threats), which is a diagnostic and decision support tool. The results show that our study area is rich in natural and cultural potential. Nevertheless, the development of tourism is lagging behind and it is therefore necessary to seek the tourism model adapted to the specificities of the region and the capacities to be developed to achieve the objectives defined by the SDAT 2030 (Master Plan for Tourism Development).

This study examines the agropolitan-based Oro-Oro Ombo Tourism Village. It aims to (1) determine the potential, (2) analyze 4-A (attraction, accessibility, amenities, and ancillary) in the development, and (3) know the achieved Village Development Index (Indeks Desa Membangun – IDM) based on the parameters of Sustainable Development Goals (SDGs) in 2021 of the village. This quantitative-descriptive study used primary data (field observations, measurements, and interviews) and secondary data (study of previous research and information from related agencies such as the Central Bureau of Statistics and Tourism Office). The data were processed using descriptive statistics from the Analysis of Operational Area of Natural Tourism Attractions and Objects (Analisis Daerah Operasional Objek dan Daya Tarik Wisata Alam – ADO-ODTWA), which was converted using scoring and single tabulation techniques. The ADO-ODTWA results show that Oro-Oro Ombo has potential tourist attractions, and based on the 4-A analysis, this tourism village has excellent local potential. These results are relevant to the IDM of Oro Oro Ombo that is 0.9981. Based on the explanation above, it shows that sustainable development in agropolitan tourism villages cannot be separated from stakeholders (government, local communities, and private parties) to optimize the local potential of the region and improve the economy and welfare of the community to achieve Indonesia’s 2021 Sustainable Development Goals.
ENVIRONMENTAL SELF-IDENTITY AND ENERGY SAVING BEHAVIOUR OF HOTEL EMPLOYEES: THE MEDIATING ROLE OF INTRINSIC MOTIVATION
Authors:   University of Limpopo, Department of Business Management, Sovenga, South Africa, FATOKI Olawale
Published: June 2022

The emission of carbon dioxide and other greenhouse gases through energy (electricity) consumption by firms is one the significant drivers of climate change. Energy conservation is one of the ways to achieve a cleaner, healthier environment and manage climate change. Energy conservation in firms is to a large extent dependent on employee participation and personal factors are significant determinants of pro-environmental behaviour. The aim of the paper is to examine the relationship between environmental self-identity and energy saving behaviour of employees of hospitality firms. In addition, the study investigates whether intrinsic motivation (measured by obligation-based intrinsic motivation and enjoyment-based intrinsic motivation) mediates the relationship between environmental self-identity and energy saving behaviour. The study uses the quantitative research design and the cross-sectional survey method is adopted for data collection. The hypotheses of the study are tested using the Partial Least Square Structural Equation modelling (PLS SEM). The results of the empirical study indicate that environmental self-identity is positively related to energy saving behaviour. The mediating effects of obligation and enjoyment-based intrinsic motivation are significant. The results suggest that intrinsic motivation is a mechanism through which environmental self-identity can affect employee energy saving behaviour.

Published: June 2022

The COVID-19 pandemic underlines the importance of geography and geographical analysis to tourism scholarship. This paper utilises a spatial approach to examine the impacts of the pandemic on tourism flows and examine the comparative performance of coastal tourism destinations in COVID-times. The case research is on South Africa one of the worst-hit countries in sub-Saharan Africa for the pandemic. Existing international literature points to a geographical change in consumer preferences for coastal destinations with reduced flows to traditional mass coastal destinations. The South African findings demonstrate the highly negative effects of the pandemic upon coastal tourism as a whole with the largest coastal cities experiencing the worst impacts. COVID-19 has caused a reversal of trends recorded for the past two decades for the benefits of coastal tourism to be concentrated in South Africa’s large coastal cities. Instead, it has resulted in the relative improvement of smaller coastal centres and in particular of centres which are relatively well-located for access to the domestic markets offered by large cities. These South African findings signal potential shifts in consumer psyche and travel behaviour as an outcome of COVID-19.

This research was conducted in Taji Village which is a village located in the Bromo Tengger Semeru (BTS) area. The purpose of this study is to explore the strategy of the local community of Taji Village in preserving the environment to support the development of the Tourism Village. The method was conducted through physical surveyand socio-economic surveys. This research started from environmental physical research in the form of landslides with a geomorphological approach. Data collection on conservation efforts and socio-economic conditions was carried out through deep interviews, purposive questionnaires and deep interviews and also observations at tourist attractions in Taji Village. Based on the results of the study, it shows that the people of Taji Village are very aware that their area is an area that is prone to landslides. The local community of Taji Village has local wisdom as a conservation effort in the form of planting multi-strata plants on each part of the slopes in Taji Village with woody plants and horticultural crops. Conservation efforts with vegetative techniques through multi-strata plants, which are part of local wisdom actually make Taji Village a village that has a tourist destination i.e Arabica coffee cultivation and supporting tourism development such some of waterfall in Taji Village. Local wisdom carried out by the local community of Taji Village is also a community survival strategy because most of the life of the Taji Village community depends on the results of agriculture with weekly, monthly and annual harvest times.

Published: June 2022

Serpantin üzerinde oluşan topraklarda Cr ve Ni gibi bazı elementler oldukça yüksek konsantrasyonlara ulaşabilmekte ve toprak sisteminde meydana gelen yer değişimleri ve kayıp süreçleriyle ekosistemi olumsuz etkileyebilmektedir. Biga yarımadasında değişik lokasyonlarda farklı arazi kullanım türleri altında serpantin toprakları bulunmaktadır. Bu çalışmada sebze tarımı yapılan Çanakkale-Ezine İlçesi anayol güzergâhındaki serpantin üzerinde oluşmuş alanlardan alınan toprak örneklerinde Co, Cr ve Ni içeriklerinin incelenmesi amaçlanmıştır. Farklı sebze yetiştirilen beş parselden alınan 15 ve kontrol amaçlı tarım yapılmayan alandan üç adet toprak numunesi çalışmanın materyalini oluşturmuştur. Metallerin jeokimyasal fraksiyonlarını belirlemek için ise ardışık ektraksiyon yöntemi kullanılmıştır. Kontrol topraklarındaki metal konsantrasyonlarının tarım yapılan toprak numunelerine göre 3-4 kat daha yüksek olduğu tespit edilmiştir. Tarım yapılan parsellerden alınan toprak numunelerinde bulunan Cr ve Ni konsantrasyonları tarımsal üretim açısından limit değerlerin üzerinde bulunmuştur. Metallerin potansiyel hareketliliği, tarım toprakları için Co (%50.6) > Ni (%19.3) > Cr (%6.7) ve kontrol için Co (%34.6) > Ni (%20.3) > Cr (%6.0) şeklindedir. Potansiyel mobil fraksiyonlar göz önüne alındığında, özellikle Co ve kısmen de Ni en fazla indirgenebilir fraksiyonda belirlenmiştir. Bu sonuç, Co ve Ni’nin çoğunlukla Fe/Mn oksitler tarafından adsorbe edildiğine veya çöktürüldüğüne işaret etmektedir. Tüm numunelerde metaller değişebilir fraksiyonda oldukça düşük oranlarda bulunmuştur. Bu durum antropojenik etkinin çok zayıf olduğunu, büyük oranda litolojik etkileşimi açıklamaktadır. Tarım ve kontrol alanı toprak numunelerinde tüm metaller çoğunlukla kalıntı fraksiyonda belirlenmiştir. Toprağın mineral yapısındaki metalleri gösteren kalıntı fraksiyonu, toprak örneklerinde bulunan Co, Cr ve Ni içeriklerinin çevre jeolojisinin özelliklerini yansıttığını göstermektedir.
Optimization of a B-pillar with tailored properties under impact loading
Authors: ÖZTÜRK İsmail
Published: June 2022

Within the study's scope, the impact performance of a boron steel B-pillar with three different hardness values and six different B-pillar designs with tailored properties was compared in crashworthiness. Impact simulation results were compared in terms of spe-cific energy absorption and peak crushing force values of the B-pillar. “Upper part T500 and lower part O25 heat treated B-pillar” gave the highest specific energy absorption. “Upper part O25 and lower part T25 heat treated B-pillar” resulted in the lowest peak crushing force and gave the second highest specific energy absorption. This pillar was used in optimization studies to maximize specific energy absorption and minimize peak crushing force. The single-objective optimization problem was solved with Adaptive Re-sponse Surface Method and Sequential Quadratic Programming methods. Specific ener-gy absorption value increased by 47.7% from 1.32 to 1.95 kJ/kg compared reference de-sign for both techniques. Multi-objective Genetic Algorithm and Global Response Sur-face Method were utilized to solve the multi-objective optimization problem, and similar Pareto front curves were obtained. For both methods, the optimal B-pillar with max spe-cific energy absorption increased the specific energy absorption by 51.5% from 1.32 to 2.00 kJ/kg compared to the reference design. However, peak crushing force increased 14.9% from 63.7 to 73.2 kN. Optimal B-pillar could be used in the automotive industry.
A History of the Common Law Double Jeopardy Principle: From Classical Antiquity to Modern Era
Authors: Coffey Ger
Published: June 2022

The double jeopardy principle is a guarantee of individual liberty that has ancient origins. The development of the principle has been incremental, and its meaning has varied through the ages. The research question and attending analyses presented in this article advances an examination of the evolution of the double jeopardy principle in historical context. Through doctrinal analysis the hypothesis advances the supposition that the common law principle was firmly established by the post-medieval period. Through an examination of landmarks in the development of the principle the article examines theoretical underpinnings and considers the extent to which the criminal justice system developed a public prosecution model of criminal justice. The incremental development of this fundamental principle of criminal justice can be explained in terms of the deficiencies in medieval criminal procedure, prejudices and practices of medieval trial procedure and punishments imposed on convicted offenders. Jurisprudence on the application of the principle indicates significant developments following the Restoration.

Drug-induced liver injury causality assessment data from a crosssectional study in Brazil: a call for the use of updated RUCAM in hospital Pharmacy
Authors: LUNARDELLI Michele M. , BECKER Matheus W. , ORTIZ Gabriela X. , BLATT Carine R.
Published: June 2022

Objective: to identify the frequency of DILI inpatients from abnormal liver enzyme levels using the updated Roussel Uclaf Causality Assessment Method (RUCAM) causality assessment algorithm, as well as to provide a descriptive analysis of DILI cases. Methods: we conducted a crosssectional study in a medium complexity hospital in southern Brazil. Data regarding DILI was collected retrospectively from electronic medical records (EMR) in 2015. Inclusion criteria were all adult patients (≥ 18 years old) who presented alanine aminotransferase (ALT) greater than twice the superior limit of normality (ALT > 60 UI/L) with concomitant change of aspartate aminotransferase (AST) or alkaline phosphatase (ALP) or change of ALP greater than twice the superior limit of normality (ALP > 250 UI/L) during hospitalization. The RUCAM was applied to all suspected DILI cases. Results: 84,134 inpatients in this period; 178 patients had abnormal liver tests, six patients had sufficient medical information to allow DILI causality assessment, and two patients had DILI described in EMR, although our group could not find suficient information to apply RUCAM retrospectively. Absence of information was mainly related to drug reconciliation at hospital admission, time of onset of suspected drug therapy and no description of previous clinical conditions in EMR. Four patients developed hepatic injury as a result of drug treatment initiated during hospitalization. Suspected drugs were antibiotics, nonsteroidal anti-inflammatory drugs, antiviral, tuberculostatics and platelet antiaggregant. Liver injury pattern was identified as hepatocellular and mixed. Conclusion: DILI appeared as a rare ADR, but absence of data in most EMR affected the application of RUCAM and underestimated DILI frequency. There is an urgency to develop DILI knowledge in Brazilian hospitals. Pharmacists must be aware of the use of the updated RUCAM to prospectively assess possible DILI cases. For future research, we suggest to combine cross-linking DILI tracers such as ICD-10 liver injury codes, abnormal liver biomarkers, search for trigger hepatotoxicity drugs and EMR text search tools, adding artificial intelligence to pharmacovigilance and hospital pharmacy.

Authors: Sulistiawati Sulistiawati , Fithria Annisa
Published: June 2022

The implementation of good corporate governance (GCG) can be seen in the relationship between the main elements of GCG mechanisms implemented by the board of commissioners (BOC) as supervisors, the board of directors (BOD) as managers, and the sharia supervisory board (SSB) as directors, consultants, and supervisors on sharia compliance of Islamic banks. This study aims to analyze the effect of corporate governance on the maqasid sharia-based performance of Islamic banks (Bank Umum Syariah–BUS) in Indonesia from 2016 to 2019. Corporate governance is proxied by the number of BOC, BOD, the audit committee, and SSB. Based on the purposive sampling criteria, 8 BUS are used as samples in this study, with a total of 32 observations. The type of data used is secondary data in the form of annual reports and GCG reports. The data analysis technique used is multiple regression analysis. The results show that BOC has a negative effect on the maqasid sharia-based performance of Islamic banks. In contrast, BOD positively impacts the maqasid sharia-based performance of Islamic banks. On the other hand, the audit committee and SSB do not affect the maqasid sharia-based performance of Islamic banks.

Abstract

Road construction often experiences problems during its construction, including in areas of expansive soil type, swelling soils, and soft soil. In Banjarmasin generally, the problem that is often faced is the construction of roads on soft clay soil. PET (Polyethylene Terephthalate) plastic waste is very common in Banjarmasin. Plastic waste is thrown away and is rarely used as an alternative solution to problems in infrastructure and other fields. This study, using PET (Polyethylene Terephthalate) plastic waste for the stabilization of soft clay soil in the city of Banjarmasin. The composition of the mixture is 1%, 3%, and 5% PET plastic waste from the total weight of the soil sample. While the size of plastic waste is varied with sizes 0.5x0.5 cm, 1x1 cm, and 2x2 cm. The purpose of this study was to determine the value of the physical properties and the value of the soil shear strength and the value of the free compressive strength of the soil before and after the addition of PET plastic waste. From the results of UCT and Direct Shear testing with PET pieces of various sizes, it can be seen that the larger the size of the PET pieces, the higher the free compression test value. The highest free compressive test value was obtained in the soil mixture with pieces of 2.0 cm x 2.0 cm with a mixture of original soil + 3% pieces of PET waste, which was 1.366 kg/cm2.
Enablers and obstacles in teaching and learning of mathematics
Authors: Kayan Fadlelmula Fatma
Published: June 2022

This paper presents results of a systematic review of papers published at the LUMAT journal on the current issues positively and negatively affecting teaching and learning in mathematics, in concurrence with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The analysis also offers insight into the most studied topics in mathematics education research, including key demographic and methodological characteristics such as year of publication, participants, education level, research methodologies, and research focus. Data was gathered from the studies published in the LUMAT: International Journal on Math, Science and Technology Education, starting from its first volume in 2013. So far, 225 articles were published in this journal, with 133 studies written in English and 51 studies related to mathematics. Although earlier studies support the notion that mathematics education is mostly traditional, this review suggests current research has thorough and positive outcomes, such that mathematics educators are likely to implement non-traditional approaches, encouraging student engagement, peer collaboration, and mathematical discourse. Certainly, in such learning environments, students tend to feel more motivated and less anxious about learning mathematics. They may also be more active and responsible in their learning, collaborate with peers, and get into mathematical discussions. Yet, there are also a number of difficulties and obstacles highlighted both in teaching and learning of mathematics. The findings might inspire several instructional implications for mathematics educators, curriculum developers, and researchers. Recommendations are given to add into what the existing literature claims and offer greater empirical evidence to support the verdicts.
“Learning models”
Authors: Eriksson Inger , Tabachnikova Natalia
Published: June 2022

The overarching aim of this article is to exemplify and analyse how some algebraic aspects of equations can be theoretically explored and reflected upon by young students in collaboration with their teacher. The article is based upon an empirical example from a case study in a grade 1 in a primary school. The chosen lesson is framed by the El’konin-Davydov curriculum (ED Curriculum) and learning activity theory in which the concept of a learning model is crucial. Of the 23 participating students, 12 were girls and 11 boys, approximately seven to eight years old. The analysis of data focuses on the use of learning models and reflective elaboration and discussions exploring algebraic structures of whole and parts. The findings indicate that it is possible to promote the youngest students’ algebraic understanding of equations through the collective and reflective use of learning models, and we conclude that the students had opportunity to develop algebraic thinking about equations as a result of their participation in the learning activity.
Languaging and conceptual understanding in engineering mathematics
Authors: Rinneheimo Kirsi-Maria , Suhonen Sami
Published: June 2022

The ability to apply mathematical concepts and procedures in relevant contexts in engineering subjects sets the fundamental basis for the mathematics competencies in engineering education. Among the plethora of digital techniques and tools arises a question: Do the students gain a deep and conceptual enough understanding of mathematics that they are able to apply mathematical concepts in engineering studies? This paper introduces the use of languaging exercises in the engineering mathematics course ‘Differential Calculus’ during the spring semester 2020, at Tampere University of Applied Sciences, TAMK. In this study, the students’ conceptual understanding and learning of differential calculus is researched. In the learning process, the languaging method is used to deepen the conceptual understanding of the concepts of differential calculus. Pre-test/post-test setup was used to see the possible gain in conceptual understanding. During the course, students did online assignments, which included languaging exercises. Students described the concepts of differential calculus using natural language, pictures, or a combination of them. The students were also asked to fill in a self-evaluation form to collect their perception of their own knowledge of mathematical skills. Mid-term and final exams summarized the acquired knowledge. The study aimed to enhance the learning outcomes and to gain a deeper understanding of mathematical concepts by exploiting the languaging method.
Evaluation of development partnership scenarios of the Croatian seaports using MAMCA analysis
Authors: Perić Hadžić Ana
Published: June 2022

The aim of this paper is to evaluate development partnership scenarios of the seaports in the Republic of Croatia using the Multi-Actor Multi-Criteria Analysis (MAMCA). Previous author’s research indicated a number of effects and criteria that PPPs need to achieve in order to ensure sustainable port development. However, implementation of partnership models in seaports in the Republic of Croatia has not reached its full potential although there has been significant progress over the last ten years. For that reason, the evaluation of the partnership models in Croatian seaports is a poorly researched issue. The author has defined three models of port development according to the degree of private investors’ involvement in Croatian ports (status quo, minimal participation and maximal participation of private sector). The author uses MAMCA as a tool to evaluate the PPP model, using relevant criteria for the evaluation of public-private partnerships (economical-financial, organizational, technical-technological, social criteria and the criteria aiming at harmonization with the policies of the European Union), from relevant stakeholders’ point of view (public interest, private interest and the interest of the wider community). The research results show that the best-evaluated model is maximal participation of private sector. It has positive influence on port development from economic and technological side, it directly contributes to different stakeholder’s interests, and in the long term, it contributes to the local community development.

Blockchain Forensics: A Modern Approach to Investigating Cybercrimes in the Age of Decentralisation
Authors: Salisu Saminu , Filipov Velitchko
Published: June 2022

Blockchain forensics (the use of scientific methods to manipulate data to create useful and informative descriptions of the manipulated data) takes data from the blockchain to interpret the flow of digital assets. Investigators use sophisticated data manipulation and visualization tools to identify the travel history of stolen assets. With these capabilities, chain hopping, round-tripping, and all attempts to blur transfer trails by cyber criminals become smoke screens with no effect. This paper establishes a framework for investigating financial crimes on the blockchain, starting with a brief explanation of blockchain forensics, types of financial crimes committed by criminals using the blockchain, and how they can be mitigated using NIST’s investigation process of data collection, data preservation, data processing, and data presentation. This paper also presents a community-based approach to financial crime investigations on the blockchain that involves the general public and victims themselves contributing valuable intelligence that can be used to trace and track criminals by authorities and security agencies in the global fight against cybercrime.

Music Cognition from Birth to Adolescence: A Structuralist Approach
Authors: Nikolsky Aleksey
Published: June 2022

This book draws a new perspective on music as a special form of cognition that provides growing children with the means to mediate their emotional state and attitude to suit their physical and social environment. My conclusions are based on new evidence coming from: 1) musicological analysis of the original and spontaneous vocalizations by children, selected to represent the milestones in the development of music cognition; 2) comprehensive research on "ear development" throughout early childhood, systematically conducted in the USSR/Russia on a large pool of subjects during the 1920-1980s; 3) data on music perception by people habituated to non-Western forms of music, including timbre-oriented music traditions of northeast Eurasia; and 4) research coming from Vygotskian school on sociogenesis and objectivization of musical sound in early childhood (published in Russian only). The principal objective of this book is to arm researchers and students with tools to analyze, interpret, and evaluate the patterns of tonal organization in children musicking - and to inter-relate these patterns to cross-cultural patterns of early verbal, social, and emotional development. Children’s musical cognition needs a thorough revision because of the old erroneous belief, still widespread amongst developmental psychologists, that the principles of Western tonality constitute a universal modus operandi, intuitively sought by children from birth. According to this view, early children’s musicking constitutes a “defective” implementation of adult’s music due to children’s deficiencies in vocal control and its coordination with hearing. In reality, early childhood musicking constitutes a peculiar type of music, different from adult’s music – very much like children’s early speech that follows its own principles, different from adult’s speech. The principles of children’s musicking ought to be inferred from the structural organization of their non-imitative attempts to make music - bottom-to-top (as opposed to the current "a priori" top-to-bottom method of describing children's music in terms of Western tonality). Some other important issues covered in this book are the goals of musical development in childhood, the issues of musical attrition, bimusicality, and normalcy of musical abilities, the modularity of musical hearing, and the relation between musical and real-life emotions.
Networks of Adversity in Childhood and Adolescence and their Relationship to Adult Mental Health
Authors: Pollmann Ayla , Fritz Jessica , Barker Edward D. , Fuhrmann Delia

Adverse events before the age of eighteen are common and include diverse experiences ranging from sexual abuse to parental divorce. These stressful events have been linked to physical and mental health issues. Previous research has focused mainly on childhood adversity, such as experiences in the family environment. Little consideration has been given to adversities that may be particularly harmful in adolescence. To understand adolescents' adverse experiences, this project used data from the Avon Longitudinal Study of Parents and Children (ALSPAC, total N = 14,901, N ≈ 1,200-10,000 per measure). We modelled interrelations of adversities in childhood (1-11 years) and adolescence (11-23 years) and examined adversity clusters using network analysis. We found two similar clusters in the childhood and adolescence networks: (1) direct abuse and (2) adverse family factors. We identified a third cluster of (3) educational and social adversities for adolescence. For both age groups, emotional abuse in the family environment was closely linked to mental health in early adulthood and most adversities were linked with depression in early adulthood. In adolescence, housing and academic issues and abuse by a romantic partner were particularly central to the network of adversities. Thus, we found commonalities and differences in the relevance of adverse experiences at different developmental stages. These findings highlight the need to develop age-dependent frameworks for adversity research and policymaking.
Rationale of Employee Turnover: An Analysis of Banking Sector in Nepal
Authors: Chaudhary Manoj Kumar
Published: June 2022

The main purpose of this study is to elaborate the reasons for employee turnover in the banking sector of Nepal .The study has opted both primary and secondary sources of data to achieve the objective of the study. The structured questionnaires were used to collect the data from the sample banks. Meanwhile, different published and unpublished reports of the selected banks were used for the analysis. The collected data were analyzed with the help of MS-excel, and SPSS descriptive statistics.  The finding of the study emphasized that employees tend to leave their current jobs due to the lack of proper environment and facilities provided by the banks. This study concludes that the Managers in the sample banks to some extent lack awareness regarding the prediction of employees’ turnover intentions. Hence, it is recommended to make clear policies and a proper plan with reference to the effective payment & reward schemes and motivational strategies to minimizethe employees’ turnover.
مبشرات السنة النبوية لبيت المقدس "دارًا للهجرة ، ودوامًا للعمران، ومقرًا للخلافة أنموذجًا".
Authors: ALDOORI Ayman

Vitiligo is a depigmentation disorder characterized by the loss of melanocytes in the skin, which is aggravated by oxidative stress. The relationship between oxidative stress and cellular senescence is still unclear despite considerable research on melanocyte senescence in vitiligo in recent years. Many chronic diseases associated with oxidative stress, that is, degenerative diseases, have been shown to ultimately result in cellular senescence due to sustained activation of reactive oxygen species. This study advances research on the pathophysiology of vitiligo and its treatment options by summarizing the role of oxidative stress and melanocyte senescence in vitiligo and investigating the mechanisms behind the interaction of melanocyte senescence with oxidative stress. Keywords: Vitiligo, melanocytes, oxidative stress, cellular senescence, age
Pharmaceutical interventions to slow human aging. Are we ready for cocktails?

Slowing human aging with pharmaceuticals is now recognized as a feasible strategy. However, the design of clinical trials is still focused on single drug approaches. The process of aging has multiple pathways, which no current drug has been shown to effectively target. Therefore, it is of interest to study combinations, or cocktails, of drugs. A recently published article reported that a drug cocktail of rapamycin, acarbose and phenylbutyrate slowed aging in middle-aged mice treated for three months. The impact of this report is discussed, with the implications for determining endpoints in humans for testing drug cocktails as well as testing other drug combinations. Keywords: Healthy aging, drug cocktail, aging mice, rapamycin, acarbose, phenylbutyrate
A computational exercise on the bureaucratic corruption within the principal-agent approach with lotteries
Authors: Matsuoka Danilo Hiroshi
Published: June 2022

This paper models a corruption problem through the principal-agent framework with lotteries where the bureaucrat is regarded as the agent and the society, as the principal. The model contemplates three variables: bureaucratic efficiency, compensation and level of honesty. Solutions for the model were given using linear program algorithms. The optimal contracts indicate that: (1) under an unmonitored scenario, it is possible that the society be better off in the presence of extreme corruption; (2) risk-loving bureaucrats can provide more righteous conducts and increase the society’s expected utility; (3) altruist bureaucrats makes the society better off while spiteful bureaucrats makes the society worse off; and (4) higher reservation utility tends to increase the probability of the bureaucrats receive a high compensation.
Problemas de agência no panorama normativo das entidades fechadas de previdência complementar (fundos de pensão)
Authors: Mano Joaquim Chacur Biasotto , Porto Antônio José Maristrello
Published: June 2022

Este estudo analisa o arcabouço legal relacionado à governança de entidades fechadas de previdência complementar, para identificar se as normas vigentes impõem a adoção de estruturas de governança eficientes, sob a ótica da teoria da agência. A governança ineficiente propicia problemas de agência que podem resultar desde má performance de investimentos, quando em níveis mais brandos, até graves danos aos investidores em razão de má conduta da administração, quando em níveis extremos. Portanto, este estudo propõe a análise da legislação, à luz da teoria da agência.
