Rock Art Recording and Documentation in Ikungi, Singida (Tanzania)
Authors:   University of Dar es Salaam, Itambu Makarius Peter
Published: April 2023

Although several research projects on rock art have been conducted in northern Tanzania, the Lake region and central Tanzania in the past, none of them has discovered cupule and gong features. Also, these early research undertakings did not document and interpret the rock engravings, cupules, hollows and gongs from the local people’s perspectives. This study sought to fill that gap through a fresh look at the rock art. It investigated and recorded ten sites in Singida region, and collected oral accounts from the local people. The fieldwork entailed systematic reconnaissance surveys which helped to discover and document more rock art sites that were not known by the scientific community as well as by the locals. Ethnographic inquiries were conducted to explore the varied meanings of the noted artistic features within the culture of the communities associated with them. Although the neighbouring Kondoa rock art sites are on the UNESCO World Heritage List, no single study has hitherto reported cupules and gongs rock engravings. Thus, this research is the first to report and discuss in detail the occurrence, types, and spread of rock paintings together with the engravings of the Singida region.

Salud mental y estrés laboral en un grupo de policías municipales
Authors: Linares Olivas Oliverio Leonel
Published: April 2023

El trabajo de policía en México se encuentra relacionado a situaciones peligrosas y de alto estrés que implica la propia naturaleza del trabajo. Las condiciones laborales precarias, además de un contexto de alta peligrosidad debido la delincuencia organizada y altos índices de corrupción. Se analizó la influencia de los estresores y apoyos personales, sociales y del trabajo, sobre los niveles de salud mental. Se encuestó a 242 policías municipales mediante un muestreo por conveniencia y se utilizó el SWS-Survey© para medir los tipos de estresores y apoyos, así como también la salud mental funcional y deficitaria. Los hallazgos muestran que los tres tipos de apoyo fueron predictores de la salud mental funcional, mientras que el estrés personal, el apoyo y el estrés sociales tuvieron influencia estadísticamente significativa con la salud mental deficitaria. Las principales fuentes de estrés laboral fueron las condiciones laborales y las relaciones con mandos.

NAVIGATING A FRACTAL WORLD: CIVILISATIONAL RENEWAL TOWARDS SUSTAINABILITY
Authors:   Independent Researcher, Malaysia, Winkel Eric
Published: April 2023

There is a conception of the Earth, the cosmos, and reality lost sometime in the 17th century (replaced by quantity, rationality, and attacks against the spiritual, the feminine, and the mythical). The present article seeks to view and consider the details of the old conception and their intriguing connections to bits and pieces of new sciences, new physics, and mathematics that deal with a world which does not look like the modern one (and which actually looks quite old).
THE DOMINION OF THE SCHOLARS: A PRELIMINARY LOOK INTO ISLĀM’S CIVILISATIONAL CONTRIBUTION IN THE PRE-MODERN REGION OF KHURĀSĀN
Authors:   Institute of Islamic Understanding Malaysia (IKIM), Malaysia, Mohd. Amin Muhammad Husni
Published: April 2023

The preliminary discussion of this short essay focuses on some of Islām’s intellectual and civilisational contributions in a historical region of Central Asia called Khurāsān. As a starting point, it mentions a number of hadīths (sayings from the Prophet Muḥammad) and athār (sayings of the Holy Prophet’s Companions and their followers) that impute to this region some eschatological importance as well as matters pertaining to the legal aspect of the religion, especially from Muslim Sunnī perspective. As a preliminary discussion and in a non-exhaustive manner, the writing highlights and evaluates a number of important Muslim figures that have emerged from that region along with their respective intellectual and cultural contributions to human civilisation as materialisation of the religion’s aspirations arising from collective understanding of its worldview.
MENILAI KEMBALI FAHAM “BUDI” MELALUI BACAAN TEKS-TEKS MANUSKRIP MELAYU HINGGA KURUN KE–18: SUATU PENELITIAN AWAL
Authors:   International Islamic University Malaysia, Malaysia, Elias Aliza
Published: April 2023

The article is a preliminary study on the concept of Malay “budi” based on the “language” used by many authors of Malay manuscipts prior to the 18th century. It attempts to clarify the impact of the worldview of Islam on the choice of keywords, formation of compounds and articulation of ideas involving the word “budi” and its network. Some main contentions made by Lim Kim Hui in his PhD dissertation (2003), a pioneering analysis on “budi” based on the Malay proverbs, shall be critically reevaluated with the hope of adding more spectrum and breadth to the present understanding on the conception of “budi.” Hence, it will further enhance the integration and perfection of the old “budi” into the worldview of Islam as practised by the Malays. This would indirectly highlight the true nature and extent of Islamisation, the role of ʿulamāʾ and kitāb tradition in strengthening and perfecting the Malays with a comprehensive understanding of “budi” projecting their new worldview. The article resolves linguistically and etymologically the choice of words, formation of compounds and structure of language used by these authors of early Malay manuscripts which were consciously planned and fashioned to be in line with the prevalent Islamic ethos regarding the nature of man and his character. In short, this article shall shed some light on the nature of Islamisation of the Malay world, especially the way it was carried out through its effective Islamisation of language.

Published: April 2023

The global increase in young consumer population and purchasing power has created a new demand for halal cosmetics product development. In Malaysia, it is now the trend in the industry of cosmetics for local manufacturers to produce halal cosmetic products. As the market growth is rapid, the manufacturers of cosmetics are eager to dominate the market and come up with many product varieties in order to pursue and satisfy customers. However, most consumers are conscious of the ingredients used in the making of cosmetic products. While the introduction of new products may facilitate companies in gaining competitive advantage, the failure rate of local products is high. Therefore, the objectives of this study are to understand the relationship between product characteristics, social influence and individual innovativeness with halal cosmetics adoption among young consumers in the Klang Valley, Malaysia. The sampling of this study comprised 350 respondents using survey questionnaires that were distributed in shopping malls in the Klang Valley. In order to test the model, this study used the structural equation modelling (SEM) technique using partial least squares (PLS) with SmartPLS 3.2.8. The findings of this study show that there is a positive relationship between product characteristics, social influence and individual innovativeness towards halal cosmetics adoption among respondents. This study demonstrates that halal cosmetics adoption is increasing among young consumers. Therefore, cosmetics producers or marketers need to understand the behaviour of young consumers in order to ensure that failure rate can be minimised.
ANALISIS KRITIKAN JASSER AUDA TERHADAP KAEDAH AL-NASKH
Authors:   Universiti Teknologi Malaysia (UTM), Malaysia, Mustafa Kamar Izal
Published: April 2023

There are various efforts by modern researchers and scholars which are aimed at introducing some kind of reformation (tajdīd) to various aspects related to uṣūl al-fiqh and maqāṣid. One of those leading contemporary reformation proponents in uṣūl al-fiqh today is Jasser Auda. This paper aims to analyse one of his proposals, which is related to the concept of al-naskh (abrogation). According to him, the principle of abrogation does not have any religious basis in the al-Qur’ān nor the Sunnah. It is instead in most situations a personal opinion of the narrator/comentator. As an alternative to alnaskh, his proposal is for the uṣūliyyūn to consider the maqāṣid (higher objectives) behind each verse (naṣṣ) in circumstances where there are disagreements between the verses (nuṣūṣ).
AL-ATTAS’S VIEW ON THE IMPORTANCE OF MAN IN OUR UNDERSTANDING OF THE COSMOS
Authors:   Attaqwa College, Pondok Pesantren At-Taqwa, Indonesia, Khayrurrijal Khayrurrijal
Published: April 2023

This article affirms man’s special position and existence as the most established point of departure in the realm of creation to comprehend both God’s existence and the cosmos. By means of the method of tafsīr-taʾwīl and muḥkamāt-mutashābihāt appropriated by al-Attas as a way of understanding the cosmos, it is argued that man proceeds to understand the different degrees of existence through his understanding of metaphors and man as a metaphorical concept. Man, then, is able to recognise a higher degree of existence that is the cause of his own existence, which is God’s existence. Furthermore, with knowledge and its transmissions through various chains of authority of knowledge, man accepts the validity of true report (khabar ṣādiq) which is especially true with regard to the reality and the truth of God’s Revelation.

Authors: Bernal Yamuca Jorge Luis , López Bravo Jair Alberto , Mora Carpio Wendy Tamara , Molina Argudo Fernando Antonio , Vivas Ibarvo Bryan Roberto
Published: April 2023

Las condiciones en que las MIPYMES se desenvuelven actualmente en América Latina no les son exclusivamente favorables, en buena parte tiene que ver con sus competencias endógenas, como el bajo grado de adopción tecnológica, mano de obra no cualificada, fragilidad administrativa, entre otros factores, pero también es cierto que ciertas condiciones institucionales y del entorno les afectan en mayor grado que a las grandes empresas. En este contexto, el presente artículo tiene como objetivo analizar los factores económicos y sociales asociados a la creación y evolución de las MIPYMES en el Ecuador durante el periodo del 2015 al 2020. Mediante la estimación de un modelo de regresión lineal múltiple, el cual se rige a la metodología econométrica tradicional, utilizando el método de mínimos cuadrados ordinarios, se determinó que la productividad laboral y el analfabetismo digital son los factores estadísticamente más relevantes y los que más influyen sobre la creación de nuevas MIPYMES en el Ecuador, mientras que la tasa de interés activa a pesar de su importancia en la dinámica microempresarial no es un factor relevante.

A Critical Review of Historical Analysis of Social Change in Nigeria from the Pre-Colonial To the Post-Colonial Period
Authors: Ari Maisule Suleiman , Bamidele Joseph , Olayemi Sennuga Samson
Published: April 2023

Changes are inevitable in both civilization as a whole and in humans. The majority of the time, social change in a country is brought about on a global scale. The intentional and unintentional changes that occur in our culture are explained by a variety of theories. They include theories on conflict, evolution, and different agents of change like invention and finding. Our society, politics, family, and even our education have all been impacted by social change. Hence, the pre-colonial, colonial, military, and what might be referred to as the democratic eras are some of the stages that the Nigerian society has gone through. Although the society undergoes changes as a result of each step, this society's desire for change has not yet been fully satiated. There is a constant search for improved social reforms and conditions because change is a fact of life. Particularly in Nigeria, societal change has occurred over time and continues to occur. It is advised that Nigeria should preserve its native language because it has played a significant role in social change since the post-Colonial era. These changes can be attributed to a number of variables, including language education, technology, modernization, environment, population, etc. It does, however, demonstrate that there are additional variables at play.
Financial Ratios: Considerations of Their Relevance to Corporate Financial Analysis and an In-Depth Look at the Major Errors Often Mar These Ratios
Authors: Maria Silvia Avi Prof.
Published: April 2023

This article focuses on financial ratios, a topic that is often considered obsolete. This leads many scholars and companies to underestimate the danger of incorrect calculations and interpretations of these ratios. Sometimes, in some articles and books, it can be perceived how the author, while addressing the issue of a company's financial situation, considers Financial ratios as obsolete analysis tools and proposes the use of much more sophisticated and complex instruments for financial analysis. This behaviour is to be stigmatised because we know that more refined and complex instruments must supplement financial ratios for a company's financial analysis to be complete. However, we disagree with considering Financial ratios as obsolete instruments. Further investigations may be performed alongside these ratios, but these ratios can never replace by any complex and, perhaps, more structured financial tool. And it should note that underestimating the importance of financial ratios frequently leads to the quantitative determination of incorrect values and the interpretation of data, even if determined correctly, that is entirely misleading and far removed from the reality that the ratios are intended to portray. For the writer, therefore, financial ratios are not only not obsolete but represent the starting point of a financial analysis that provides company management with indispensable information on the development of the financial situation of the company to which they belongAnalysis of a company's financial situation is not feasible except by comparing specific data with other values. Absolute values do not allow one to judge the 'trend of the company's financial situation. For this reason, it is well-known that particular ratios are used to understand whether the enterprise enjoys excellent health or has more or less severe problems financially. Often the determination of these ratios starts foot, by some scholars and by many companies, using aggregates, unsuitable for the analysis to be complete and correct. In some instances, it is also noticeable how ratios are determined whose informational value is practically null. As a result, a calculation of them is an interpretation that can be downright misleading regarding the situation being experienced, at a given instant, the enterprise under analysis. And it should be noted how using ratios alone is insufficient to carry out a financial analysis point. The completion of proportions with dynamic analysis is essential, and therefore, for this reason, the preparation of a cash flow statement should be considered indispensable completion of purely financial ratios.

Published: April 2023

The emergence of the Covid-19 virus in the city of Wuhan in the state of China, since March 2020 has almost covered the entire care business sector, from MSMEs, service companies and industry to even universities. Universities in Indonesia have also experienced a decline in revenue and operational costs. One of the higher education institutions in Indonesia is the Mahaputra Riau College of Economics (STIE Mahaputra Riau). The aim of the study was to see the difference in income and operational costs of STIE Mahaputra Riau both before and during the Covid-19 pandemic. The research method uses a comparative method with a quantitative description approach. The data used is in the form of secondary data from financial reports at STIE Mahaputra Riau during the 2018–2021 period. The results showed that the income experienced by the STIE Mahaputra Riau campus both before and during the Covid-19 pandemic fluctuated every month, but in total income during the Covid-19 pandemic was higher than income before the Covid-19 pandemic with an increase of 0.30%. While the operational costs experienced by the STIE Mahaputra Riau campus both before and during the Covid-19 pandemic fluctuated every month, the total operational costs during the Covid-19 pandemic were lower compared to operational costs before the Covid-19 pandemic with a total reduction in operational costs of -6.36%. The findings from this study are that income increased during the Covid-19 pandemic due to an increase in the number of registrations in 2020 so that it affected STIE Mahaputra Riau's income, while operational costs decreased due to the implementation of online lectures.
Pemodelan Pertumbuhan E-Commerce di Indonesia dengan Spatial Autoregresive Model (SAR)
Authors: Purwanti Yuniasih
Published: April 2023

The development of information technology has had a significant impact on the growth of e-commerce in Indonesia. However, the distribution of e-commerce is still concentrated in Java and Sumatera. It shows the inequality of the distribution of the e-commerce industry. Therefore, this study attempted to model the growth of e-commerce by considering the effect of dependence between regions. The variables use in this study included economic growth, base transceiver station (BTS), computer use, cellular phone ownership and the availability of strong signals (4G). The methods used were the Spatial Autoregressive Model (SAR) and the Spatial Error Model (SEM). The study's results showed that the SAR model was better than the SEM model. In addition, the test results indicated an autocorrelation relationship between provinces, which means that the growth of e-commerce in a province will be followed by an increase in e-commerce in the surrounding region. Meanwhile, the e-commerce growth in a province was affected by BTS, computer and telephone use, the availability of strong signals, and spatial residuals from other provinces that are close to each other.

Selection and Evaluation of Test Data Sets Based on Genetic Programming
Authors: Emer Maria Claudia F. P. , Vergilio Silvia Regina
Published: April 2023

A testing criterion is a predicate to be satisfied and generally addresses two important questions related to: 1) the selection of test cases capable of revealing as many faults as possible; and 2) the evaluation of a test set to consider the test ended. Studies show that fault based criteria, such as mutation testing, are very efficacious, but very expensive in terms of the number of test cases. Mutation testing uses mutation operators to generate alternatives for the program P under test. The goal is to derive test cases to producing different behaviours in P and its alternatives. This approach usually does not allow the test of interaction between faults since the alternative differs from P by a simple modification. This work explores the use of Genetic Programming (GP) to derive alternatives for testing P and describes two GP-based test procedures for selection and evaluation of test data. Experimental results show the GP approach applicability and allow comparison with mutation testing.

Authors: Barros Juliana R. B. D. , Ferraz Carlos A. G.
Published: April 2023

Aplicações distribuídas com suporte a tempo real fazem parte de um tipo emergente de aplicação. Neste tipo de sistema podem ser encontrados alguns fortes requisitos de qualidade de serviço e recursos temporais. Embora exista esta tendência de utilização de sistemas que atendam a requisitos de tempo e qualidade de serviços, os sistemas que já atingiram uma certa maturidade em ambientes corporativos não podem simplesmente ser abandonados e redesenvolvidos com a intensão de atender a tais restrições. Com o objetivo de encontrar uma solução para isto, este artigo apresenta duas estratégias de migração de sistemas distribuídos legados para sistemas de tempo real, utilizando as especificações de Real-time CORBA e CORBA Messaging.

Published: April 2023

A Object Constraint Language (OCL) é uma linguagem proposta para ser utilizada em conjunto com outras ferramentas, tais como os diagramas de classe da UML, e que serve para especificar restrições em um modelo de classes. Além disso, existem uma série de abordagens propondo o uso de OCL para a documentação de Regras de Negócio. Embora a OCL seja uma linguagem declarativa e de fácil entendimento, programadores pouco familiarizados com ela podem ter certa dificuldade em entender expressões em OCL. Este artigo apresenta a ferramenta FalaOCL. Esta ferramenta é um módulo parafraseasor de OCL, ou seja, dada uma expressão em OCL, a ferramenta gera um texto que explica, em linguagem natural, a expressão dada. Com isso, é possível a um usuário sem habilidades de programação em OCL entender expressões em OCL, facilitando o trabalho de validação e manutenção do sistema.

Published: April 2023

Mutation Testing is a testing approach for assessing the adequacy of a set of test cases by analyzing their ability in distinguishing the product under test from a set of alternative products, the so-called mutants. The mutants are generated from the product under test by applying a set of mutant operators, which systematically yield products with slight syntactical differences. Aiming at automating the generation of mutants, we have designed a language — named MuDeL — for describing mutant operators. In this paper, we describe the mudelgen system, which was developed to support the language MuDeL. mudelgen was developed using concepts that come from transformational and logical programming paradigms, as well as from context-free grammar and denotational semantics theories.

Ensuring Meaningful Access to Powerful Knowledge to Enable Success of Students from Rural Areas in the Field of Science in Higher Education: A Decolonial Perspective
Authors: Emmanuel Madondo Nkosinathi
Published: April 2023

The dominant discourse in higher education which rather simplistically equates hard work with success, serves to privilege the already privileged, with their background in particular forms of knowledge and learning. The assumption that success in higher education could largely be explained through meritocracy based on hard work and bright minds only favors middle class students, globally, because of their privilege. This is because students’ enrollment in universities is linked to benefitting from powerful knowledge, but this is likely to be merged with the acquisition of the knowledge of the powerful, the middle and upper classes. Consequently, students from lower class backgrounds are unlikely to draw on knowledge resources that they bring with them to university. Through empirical qualitative data drawn from discussions of 2nd year science students at a historically white and privileged university, I argue that knowledges outside of the academy, for example, in rural homes could be used as a pathway to access powerful knowledge. I draw on the theoretical lenses of critical realism and social realism to develop an understanding of students’ prior experiences. A decolonial gaze is adopted to critique how university space, physical, ideological, and intellectual, could constrain access to powerful knowledge.
Regular Physical Activity Influences Gut Microbiota with Positive Health Effects
Authors: Jurdana Mihaela , Barlič Maganja Darja
Published: April 2023

The gut microbiota is believed to have a major impact on human health and disease. It is involved in barrier functions and maintenance of homeostasis. It provides nutrients and metabolites, participates in a signaling network, regulates epithelial development, and influences the immune system as well as protects the intestinal mucosa from the aggression of pathogenic microorganisms. There is growing evidence that physical activity has an impact on the gut microbiota. Recent studies in animals and humans suggest that regular physical activity increases the presence of beneficial microbial species and improves host health. However, some specific differences should be noted: different forms of physical activity, frequency or intensity, aerobic or resistance training, and benefits and consequences for amateur or competitive athletes. Because the positive role of physical activity can have an impact on health and various types of diseases, the results of research studies in this area are increasingly becoming the focus of scientific interest. In addition, probiotic supplements modulate intestinal microbial flora, and the ability of probiotics to modulate perturbations in immune function after exercise highlights their potential for use in individuals exposed to high levels of physical activity.
An Insight towards the Design of a Ruthenium-Containing Biomaterial
Authors: Nkomo Duduzile , Phasha Maje , Moller Hein
Published: April 2023

Ruthenium (Ru) is one of the platinum group metals (PGMs). These metals belong to the transition metals group of the periodic table. They have excellent properties such as high melting point and are inert with variety of substances, thus also called noble metals. Currently, Ru is the cheapest of the PGMs, thus it is readily available compared to other PGMs. Recently, incorporating PGMs in shape memory alloys (SMAs) has been extensively explored, with titanium-nickel (TiNi) used as a bench-mark material. TiRu is amongst the compounds that are currently explored for various potential applications. This compound has an ordered B2 (CsCl-type) crystal structure. It is hard and brittle, thus some shape memory (SM) properties are difficult to induce in this compound. However, due to Ru possessing some good biomedical properties such as biocompatibility, corrosion resistance, improved radiopacity and ultra-low magnetic susceptibility for MRI diagnostics, the mechanical properties of TiRu must be improved for biomedical applications. Since niobium (Nb) is known to be biocompatible and is usually studied in biomedical alloys, a systematic substitution of Ti with niobium (Nb) was performed in an effort to reduce the stiffness (Young’s modulus). This chapter gives an insight on the structural and mechanical properties of biocompatible Ru-rich alloy compositions.

Penelitian ini bertujuan untuk Menguji Pelatihan dan Disiplin Kerja terhadap Kinerja Karyawan pada PT Persona Prima Utama. Jenis penelitian ini bersifat deskriptif kualitatif. Teknik pengumpulan data dengan cara kuesioner, dan tehnik analisis data dengan uji instrument, uji asumsi klasik, regresi linier berganda, koefisien korelasi, koefisien determinasi dan uji thitung dan uji Fhitung.  Pengaruh Pelatihan terhadap Kinerja karyawan PT. Persona Prima Utama dengan pengujian hipotesis (H1) telah membuktikan bahwa terdapat pengaruh Pelatihan terhadap Kinerja karyawan. Berdasarkan perhitungan regresi di peroleh hasil Y= 1,083 + 0,104X1 yang menunjukan bahwa pada saat Pelatihan (X1) bernilai nol, maka Kinerja karyawan (Y) akan bernilai 1,083. Sedangkan nilai b yaitu sebesar 0,104 menunjukan bahwa ketika terjadi kenaikan Pelatihan sebesar satu satuan, maka Kinerja karyawan akan meningkat sebesar 0,104 satuan. Melalui hasil perhitungan yang dilakukan maka diperoleh nilai thitung 0,970 < ttabel 1,673 dan tingkat t < 0,05 (0,000 < 0,05). Karena thitung nilainya positif tapi lebih kecil dari ttabel maka dapat disimpulkan bahwa secara parsial Pelatihan (X1) tidak memiliki pengaruh yang bermakna terhadap Kinerja karyawan (Y) pada PT. Persona Prima Utama.
