Environmental Law and Policy in Tanzania: Reflections on the Enforcement of The Environmental Management Act
Authors:   University of Dar es Salaam School of Law, Mapunda Benedict Thomas
Published: December 2022

Tanzania is a vast country with adverse environment that needs to be protected for the good of current and future generations. The government has adopted environmental policies and enacted laws in order to protect the environment. The leading legislation in this effort is the Environmental Management Act which contains relatively comprehensive provisions which, if properly enforced, can help to protect and conserve the environment of the country. This article argues that the Act is not fully enforced not only by individual citizens but also relevant government institutions and as a result the intended objectives for its enactment are not fully realized. Using all the available avenues of enforcement, public education and collaboration among state organs will help to protect the environment. Key Words: Environment, policy, biological diversity, enforcement

Published: December 2022

Metaverse is a virtual reality (VR) environment with avatars and software agents using the internet and augmented reality (AR). This one is described as a new iteration of the internet, Metaverse uses VR headsets, blockchain technology and avatars in a new fusion of real and virtual worlds. The role of the programmer in the metaverse is to create and maintain programs that control the behavior of virtual objects and entities within the virtual space. This can include characters controlled by the computer, animations, special effects, and other visual and interactive elements. Programmers in the metaverse may work on a variety of different projects, such as developing new virtual worlds, creating games or other interactive experiences, or building tools and applications for use within the metaverse. They may also be responsible for maintaining and updating existing programs, fixing bugs, and optimizing performance. The main challenge facing programmers in the metaverse is creating a seamless and immersive experience for users. This involves designing and implementing a wide range of features, such as realistic and interactive 3D environments, avatars, physics and interactions, network communication and synchronization, and AI-powered non-player characters. The development of the metaverse requires a wide range of skills and technologies, including expertise in computer graphics, networking, AI, and user experience design.
Mass Culture of the Postmodern Epoch in Light of the Philosophy of Postmodernism
Authors:   Far Eastern State Technical Fisheries University, Tsareva Nadezhda A.
Published: December 2022

Mass culture presents the most important phenomenon of society without which it becomes difficult to perceive the realities of the 21st century. The postmodern era has exerted influence on the qualities of the mass culture of the metamodern age. In order to understand its new characteristic features and forms of existence it is important to indicate the connection with the philosophy of postmodernism. The aim of the present article is to research the rhizomatic model of culture of philosophy of postmodernism and to reveal in it the bases of the transformation of mass culture in the metamodern epoch. The author systematizes the evaluations of 21st century mass culture, defines its peculiarities in the paradigm of the culture of the metamodern age with the use of rhizome-analysis as a scholarly approach. On the basis of comprehension of the rhizomatic model of culture in the philosophy of postmodernism the conclusion is arrived at: the ideas of decentration, multiplicity and plurality explain in many ways the new characteristic features of mass culture. It may be examined as an open system endowed with the creative potential of self-organization and acquiring new features in various sociocultural systems. The contradictory evaluations of contemporary mass culture in the 21st century make it possible to reveal both its negative (its entertaining character, commercialization, creation of virtual reality, manipulation of consciousness, a threat to national culture, etc.) and its positive characteristic features (its democratic quality, accessibility, mass character, etc.). Application of the concept of the rhizome as a method makes it possible to study the particularities of mass culture, to open up new verges of the phenomenon of the metamodern epoch. The transformation of mass culture expressed in synthesizing the elite and mass cultures, art and mundanity, the real and the ideal.

Authors:   Lipetsk State Pedagogical University named after P. P. Semenov-Tian-Shansky, Shefova Elena A.
Published: December 2022

The article examines the specificity of manifestation of the images of nature on the material of children’s piano album What the Finch Sang About by Nikolai Sidelnikov (1930–1992). The image of nature is own of the predominant features in the composer’s musical output. In the narrative such aspects as landscapes, the vegetative and animal worlds, weather conditions, water, and the heavenly hosts are reflected. An analysis of the miniatures makes it possible to see the ambiguousness of the image, and also reveals the emotional-psychological significance which reveals itself in the pieces. The author comes up with the conclusion that the image of nature in the composer’s narrative is presented on the level of the musical-expressive means – genre, figurativeness and theatricality, which creates a particular mood and is conducive for expansion of the concert and pedagogical repertoire.

Published: December 2022

A feeding trial was conducted to assess the effect of incorporating dried green aquatic fern Azolla (Azolla microphylla) in the diet of lactating Murrah buffaloes. Ten multiparous Murrah buffaloes with an average body weight of 499.34±20.71 kg, parity of 2.4±0.31, average milk yield of 11.29±0.51 kg and average days in milk 30.40±3.86 were distributed randomly into two equal groups. One of the groups served as control and fed concentrate mixture prepared by Wheat bran, Maize grain, Mustard cake, Cotton seed cake, Groundnut cake, mineral mixture, and salt, while in treatment group 10% of the dried Azolla was incorporated in the concentrate mixture to make both the concentrate mixtures iso-nitrogenous and iso-caloric. Milk quantity was recorded and milk components including protein, fat, lactose, solids not fat and total solids were assessed at the day before starting experimental feeding and followed by a weekly interval for four week.After 28 days of experimental feeding no significant (P>0.05) effect was apparent on total milk production, but fall in production of fat corrected milk was 23.54% in the control group as compared to only 8.24% in the Treatment group, which indicated the superiority of Azolla based concentrate mixture over control concentrate mixture. No significant (P>0.05) variation was also observed in the quality of milk produced including milk protein, fat, lactose, solids not fat and total solids between the milk of buffaloes fed with two different concentrate mixtures. Results indicated that feeding of concentrate mixture consisting of 10% dried Azolla helped to maintain the production of fat corrected milk in early lactating Murrah buffaloes without affecting the intake of nutrients.

Published: December 2022

The study assessed the impact of franchising clothing/textile enterprise in Benue State. Objectives were to assess the awareness of franchising, examine the impact of clothing/textile franchising enterprise on employment generation, identify the challenges of franchising in Benue State, and the way forward. Sixty-five clothing stores across Benue were assessed. Questionnaire was used for data collection. The findings of the study are inadequate media publicity, lack of franchise general regulation, and ignorance about franchising leads to low level of awareness. Franchising contributes to public policy initiatives of employment creation and poverty reduction, revenue generation, and sustainability. Also, lack of start-up capital, difficulties in accessing finances, and inadequate infrastructure are some of the challenges of franchising in the State. The way forward includes that government policies towards franchising should be favorable, and banks and other money lenders should make cash available to people who may want to engage in franchising, among others. In conclusion, since franchising does generate employment for Benue State, it should be made known to the people to invest in it. The study therefore recommended that, government and other sectors should create adequate awareness through media, seminars and workshops on franchising.

Published: December 2022

The impact of exchange rate misalignment on economic growth has become an important research topic in recent years in many different countries. Especially, in the context of global economic turmoil and trading conflicts between China and the United States, many countries have raised interest rates to combat rising inflation. Governments try to find suitable exchange rate policies to help stabilize the inflation and develop their economies. This paper aims to analyze the misalignment of the real effective exchange rate in Vietnam by using the Behavioral equilibrium exchange rate and purchasing power parity model. The result shows that the Vietnam Dong was undervalued in the period 2000-2010 and overvalued in the period 2010-2020.

Published: December 2022

In the social security system, the State plays a leading role in building the mechanisms, policies and programs on social security. Businesses and social communities also have a responsibility to share the burden with the State to help all members of society cope with social and economic risks that reduce or cause loss of income sources due to objective and subjective reasons. The article presents the basic theory of implementing social security for employees according to the theory of sharing corporate social responsibility, using the Kano - IPA integration model to analyze the current situation of implementing social security for employees at enterprises in Vietnam. From there, the authors propose a number of strategies for enterprises to ensure the implementation of social security for employees according to the theory of sharing corporate social responsibility.
How Does Firm Location Affect Cash Holdings?
Authors: Duc Kien Vu
Published: December 2022

Using a sample of Vietnamese listed companies, this study finds a statistically significant relationship between geographical location and cash holdings. Companies located in the two biggest financial centers, Hanoi and Ho Chi Minh City, have about a two percent higher cash over assets ratio than companies located in other regions. In addition, the average enterprises in five cities under the jurisdiction of the central government (Hanoi, Ho Chi Minh City, Da Nang, Can Tho, and Hai Phong) also have a higher cash-over-assets ratio of about two percent more than their counterparts in the provinces. If geographical location is measured as the distance from the firms’ headquarters to Hanoi or Ho Chi Minh City, the analysis still shows robust evidence.
Impacts of COVID-19 on Vietnamese Bank Performance: The Role of Bank Diversification
Authors: Thi Minh Giang Thao
Published: December 2022

Although the COVID-19 pandemic has been undisputedly found to exert negative impacts on bank performance in general and their traditional lending activities specifically, the strategy of banks to deal with such a problem is still an open question. Our study attempts to answer this question through an empirical analysis of the impacts of COVID-19 on bank performance and the role of bank diversification. Specifically, data of all listed commercial banks in Vietnam over the period from 2015 to 2021 are estimated by the two-step system GMM models. COVID-19 is confirmed to have negative impacts on bank profitability. Bank diversification is found to increase bank profitability over the entire study period. Additionally, the study contributes to the extant literature by offering evidence that bank diversification has helped preserve bank profitability during COVID-19. It is suggested that to deal with the worsened traditional lending activities, diversification towards non-interest activities is an effective strategy for banks to improve their performance.

Published: December 2022

Carrying out corporate social responsibility (CSR) not only brings benefits to the community but also benefits the business itself. There are many studies on the application of CSR in business strategies to create competitive advantages and sustainable development. However, CSR is still a new term in Vietnam, and the concept has various definitions and most studies are mainly theory-based with limited research on the real situation of CSR practices, especially in the case of FDI firms. Therefore, this study aims to investigate the impact of CSR implementation on corporate strategic goals, including reputation, innovation and differentiation of FDI firms in Vietnam. This study uses regression models to analyze survey data of 224 FDI enterprises in Hanoi, the capital of Vietnam. The empirical results indicated that implementing CSR significantly impacts improving the efficiency of deploying three business strategic goals: enhancing reputation, enhancing innovation, and creating a competitive advantage. The findings of this study suggest that FDI enterprises in Vietnam need to renew their perspectives and approaches to integrate and implement CSR, not only seeing CSR as a costly obligation or merely charitable activities, but truly an opportunity to create competitive advantages and sustainable development.

Published: December 2022

Sustainability report is a report produced by firms which disclose their economic, environmental and social performance. These reports are normally geared toward the attainment of the United Nations sustainable development goals (SDGs). Even though compliance is voluntary in Nigeria, its effects on firm’s financial performance are enormous and as a result, it is essential for firm’s prosperity as well as better financial performance. This study examines the effect of sustainability reporting on financial performance of quoted Nigerian oil and gas firms. The population of the study comprises 12 listed oil and gas firms in Nigeria. Census sampling technique was adopted and filter was used. For firm to be selected it must be listed on or before 1st January 2009 and remain listed up to 31st December 2019. The firm must also publish their annual reports for the relevant period of the study. Based on these, five firms that failed to meet the set criteria were filtered out. This study makes use of Return on Asset to measure financial performance. Secondary source was used to collect the relevant data. Data in relation to sustainability reporting were extracted from the firm’s annual reports as well as standalone sustainability reports. However, data in relation financial performance were collected from the firm’s annual reports. Data for this study were analyse using STATA 13 statistical software. The regression result revealed that economic sustainability has a positive insignificant effect on ROA; environmental sustainability has a positive significant effect on ROA while social sustainability has a positive insignificant effect on ROA. Based on the findings, this study therefore, concludes that sustainability reporting has a significant effect on the financial performance of listed oil and gas firms in Nigeria. This study therefore, recommends among others that, listed Nigerian oil and gas firms should emphasize more on reporting their sustainability activities as it is capable of improving their financial performance. The policy makers and standard setting organisations should facilitate the issuance of a sector specific reporting guidelines to facilitate compliance.

From the discussion on the insertion of computational concepts in Basic Education in Brazil, there has been a growing demand for support to these teachers in the form of training courses in computing, whether offered by formal bodies or even by independent projects such as the university extension. If, on the one hand, the offer of these courses fulfills the role of helping Basic Education teachers in this challenge of integrating computational concepts in their classroom practice, on the other hand, these training courses also have the potential to engage teachers to attract their students to the area of ​​computing as a profession. We argue that because many girls are rarely exposed to content in this area in particular, and hearing quality clarifications from their teachers can spark previously unexplored curiosities. However, in order to fulfill this second role, it is necessary to discuss how these courses are approached in order to break with certain stereotypes, such as gender, which have long been perceived in this area. In this sense, this article highlights this demand for training courses in computing free of stereotypes, since it identifies a perception that is still stereotyped, a possible reflection of a clear lack of basic education teachers in training courses offered by the TIChers extension project.

Published: December 2022

Background: Post-laparoscopic cholecystectomy (LC) pain control is still an issue postoperatively. Objectives: We investigated the effectiveness of the unilateral right-side ultrasound-guided erector spinae plane block (ESPB) on post-LC pain intensity and opioid consumption. Methods: This is a parallel-arm randomized control trial on 62 adult patients with an American Society of Anesthesiologists (ASA) physical status ≤ 2 who underwent LC. The patients were randomized into 2 groups (the block group [BG] and the control group [CG]; n = 31 per group). BG received a single-shot right-sided T7 ESPB with 20 mL of 0.2% ropivacaine at arrival time in the post-anesthesia care unit (PACU). CG) received no regional anesthesia. Both groups received patient-controlled intravenous fentanyl and rescue meperidine for analgesia. The primary outcome was the pain intensity determined using a Numerical Rating Scale (NRS) in the first 24 hours after surgery. Secondary outcomes included total fentanyl and meperidine consumption within 24 hours. Results: Median pain scores were significantly higher in CG at rest and with coughing up to 12 hours after surgery compared with BG. Pain scores were higher in CG with a cough at 24 hours compared with BG (median 1 [interquartile range (IQR) 1, 2] vs. 1 [1, 0]; P = 0.0005). Total fentanyl consumption and meperidine consumption within 24 hours were significantly lower in BG compared with CG (median 60 µg [IQR 60, 90] vs 250 µg [90, 300]; P < 0.0001 and median 20 µg [IQR 10, 20] vs 25 [20, 25]; P = 0.002, respectively). Conclusions: A single-shot, right-sided, unilateral ESPB decreases post-LC opioid consumption and pain.

Published: December 2022

Context: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease of 2019 (COVID-19). Pulmonary manifestations have been identified as the common symptom, and patients present a wide range of hematologic changes depending on the flow of the diseases. The interpretation and treatment of hematological complications in COVID-19 patients are very challenging. There are limited guidelines thus far due to the novelty of the disease. Evidence Acquisition: This review summarizes the hematological findings (platelet and coagulation/fibrinolytic) in COVID-19 patients and discusses possible mechanisms for their changes. Results: The results showed that the common findings were thrombocytopenia, elevated D-dimer levels, and prolonged prothrombin time (PT) and partial thromboplastin time (PTT) in severe patients. Conclusions: Attention to hematological changes may be helpful biomarkers in diagnosing and determining patients needing intensive care, as well as monitoring the treatment process and treatment effects on COVID-19 patients.

İktisadi kalkınma olgusunun ölçülmesinde ülkelerin ekonomik, demografik, sosyal, kültürel ve siyasal yapılarında meydana gelen farklılıkların bulunması bu kavramın tek bir ölçütle belirlenmesine engel olmaktadır. Bu durumda insani gelişme raporunda da belirtildiği gibi kalkınmanın amaçları ve araçları arasında temel bir ayrımın yapılmasını zorunlu kılmaktadır. Kalkınma ekolü gelişme ekonomisi olarak da adlandırılmakta ve ‘ekonomik büyüme’ ve ‘insani gelişme’ olmak üzere iki ayrı çerçevede incelenmektedir. Günümüzde teknolojik alanda meydana gelen gelişmeler; ekonomik gelişimin tetikleyici, insani gelişiminde itici gücü olmaktadır. Küresel piyasalarda ülkeler elde ettikleri bu güç doğrultusunda orta ve uzun vadede üstünlük elde etme ve rekabetçi yapılarını da koruma arzusu içindedirler.

Ekonomide kalkınma kavramı, inovasyon kavramı ve rekabet gücü kavramları arasında domino etkisi söz konusudur. Şöyle ki inovatif bir ülkede yaşanan gelişmeler rekabet gücünü arttırmakta, rekabet gücü ve inovasyon içeren ülkelerde kalkınmaktadır. Kalkınma gelişmekte olan ülkeler için önemli bir süreçtir. Bu süreç içerisindeki ekonomik hamlelerin doğru atılması, gelişmekte olan ülkelerin gelişmiş ülke seviyesine yükselmesinde ve toplumsal refah elde etmesinde büyük önem taşımaktadır.

Bu çalışmada gelişmekte olan G-20 ülkelerinde rekabet ve inovasyon değişkenlerinin ekonomik kalkınma ilişkisinin panel veri analizi kullanılarak araştırılması amaçlanmaktadır. Bu amaç doğrultusunda verisine ulaşılabilinen 13 G-20 ülkesi 1997-2018 dönemleri arasında incelenmiştir. Çalışmada panel veri analizi tekniklerinden yararlanılmıştır. Çalışma sonuçlarına göre; ekonomik kalkınma ile rekabet ve inovasyon değişkenlerinin uzun dönende ilişkili oldukları ve bu değişkenler arasında pozitif nedensel ilişkinin bulunduğu sonucuna ulaşılmıştır.

In many real-life situations, data consists of entities and the connections between them, which are naturally described by a complex network (graph). The structure of the network is often such that it is possible to group nodes based on the existence of connections between them, where such groups are called clusters (communities, modules). If the nodes are allowed to partially belong to clusters, they are called fuzzy (overlapping) clusters. There is a huge number of algorithms in the literature that perform fuzzy clustering, that is finds overlapping clusters, so a mechanism is needed to evaluate such clustering. The function that assesses the quality of a performed clustering is called the cluster quality function. One of the latest proposed quality functions is the E-function. The E-function is based on a comparison of the internal structure of a cluster, i.e., the connection between nodes within a cluster and the connection of its nodes with the nodes of other clusters. Due to its exponential nature, the E-function is sensitive to small changes in the membership degrees to which the nodes belong to clusters. As such, it has shown good results in evaluating clustering on known data sets. In this paper, the experimental results that the modified E-function achieves in the case of overlapping clusters are presented. Also, some possibilities for fuzzy clustering by optimizing the E-function are displayed.

Development of plaques compositions caused by atherosclerosis inside of coronary arteries is known as coronary artery disease. Its treatment includes the possibility of stent deployment through operation called percutaneous transluminal coronary angioplasty. In this procedure stent is delivered using a balloon catheter and then inserted across the lesion. The new stent design development or optimization of existing ones requires the performance of many expensive mechanical tests which are always followed by their time-consuming analysis. Thus, the possibility of those tests to be performed on computer, i.e., in-silico, instead of in reality, i.e. invitro could remove the necessity of a greater number of in-vitro tests. With in-silico mechanical testing the analysis of all mechanical characteristics could be performed which would drastically decrease both the time and the expenses of the process and even gives the possibility to compare two or more designs. In this study, recently introduced material model of PolyL-Lactic Acid (PLLA) fully bioresorbable vascular scaffold and recently accredited numerical InSilc platform were used to perform in-silico mechanical tests on different stent designs that have different geometrical and material characteristics. In-silico tests include radial compression (RCI), inflation, three-point bending and two plate crush test whose results could provide well-grounded conclusions and thus a notable contribution in stent design and optimization.

This is one of the few proposed integrated platforms that include different areas of bioengineering. The platform includes already developed solutions, various datasets and models related to cancer, cardiovascular, bone disorders, and tissue engineering. The biggest obstacle in designing a platform of this type is the use of different tools for each of the layers of architecture for models which are created using different technologies and their integration and visualization within a platform. This study describes the technologies that were used for building the platform and methods for data and models visualization. The goal was to build the most flexible system capable of executing tools of various nature and connecting them into a platform.

The human body, as a complex biomechanical system, is daily exposed to oscillatory movements. Vibrations are observed as small displacements of points compared to the dimensions of the system. The body's sensitivity to vibration depends on many factors, such as body position, muscle tension, frequency, amplitude, and direction of vibration. Comfort is one of the important factors in the study of the quality of the vehicle. Exposure to vibrations over a long time can seriously and permanently damage some organs of the body. In this paper, the influence of vibrations on the lumbar part of the human body was investigated. Vibrations were determined experimentally while the vehicle was moving on the highway for the case of two different speeds. A 3D computer model of a lumbar spine was developed using CT scans. The acceleration values obtained by the experiment were the input values for the numerical analysis of the lumbar spine using the Ansys software package.

The purpose of this research was to determine the physical fitness profile of students in terms of sports activities. The quantitative description was the method of this research. The data collection technique used was the Indonesian Physical Fitness Test. The results showed that the fitness level of SMP Sekolah Alam Indonesia students was 0% in the excellent and good category, 31% in the medium category, 36% in the low category, and 33% in the poor category. The calculation obtained a significance value of more than 0.05, meaning the sample variance was normal. Thus, the hypothesis that the variance of the existing variables was the same was accepted. To determine whether there was a difference between sports activities and the fitness profile of SMP SAI students, the researchers performed the independent sample t-test on the data taken from the Indonesian Physical Fitness Test. The obtained significance value was 0.000 (less than 0.05). Therefore, it can be interpreted that there was a significant difference between the Fitness Profile of SMP SAI students and sports activities. In conclusion, the 8th-grade students of the school have not yet reached the good and excellent categories. The more active students are in exercising, the better their physical fitness level will be.

Published: December 2022

There is only one management function involved in the management of advice and counseling, which is controlling (supervision). Supervision is an essential component of the guidance and counseling program. As a result, academic monitoring implemented by both school supervisors and school principals is linked to the professional performance of guidance and counseling teachers. The purpose of this study is to investigate the impact of academic supervision implementation on the professional performance of guidance and counseling teachers using self-efficacy as an intervening variable. This study employs quantitative tools and a correlational research design. The study involved guidance and counseling teachers from the State Junior High School in Pemalang Regency. According to the study's findings, academic monitoring by school supervisors is still not equivalent since the number of school supervisors is still limited compared to the number of schools and teachers in the Pemalang Regency. However, the study's findings also suggest that academic supervision impacts the professional performance of guidance and counseling teachers at SMP Negeri Pemalang Regency. Furthermore, this element of self-efficacy demonstrates that the outcomes have no substantial positive influence. That is, academic supervision does not mediate between Guidance and Counseling teachers' professional performance.
