Authors: Omary Eddie , Pastory Dickson
Published: August 2022

This study investigated on Determinant of tax compliance among Small and Medium Enterprises in Tanzania specifically Ilala municipality, Particular objectives included evaluating the influence of economic factors and taxpayer personal demographics on tax compliance.  The descriptive cross-sectional survey design and quantitative research approach were used in the current study. The study's population consisted of 5324 Small and Medium Enterprises from Ilala Municipality, from where a random sample of 98 respondents was drawn. Structured questionnaires were used to collect data, which was then analyzed using The Multiple Linear Regression, which provided a comprehensive proof that helped to answer the research questions. The study's findings demonstrated a positive and statistically significant association between the study independent variables and the dependent variable. Taxpayer, economic, and institutional factors all influence taxpayers' willingness to engage in tax evasion, according to the regression analysis. Study findings reveal that all taxpayer predictors, including economic and institutional factors, have a significant impact on tax compliance since all have mean of above 3.0. Furthermore, regression analysis supports the findings, since all three factors were found to have a significant impact on tax compliance, with p-values less than the 0.05 cutoff limit. The study concludes Tax morality can help increase voluntary tax compliance on the country through this taxpayer will have a positive perception toward government spending. Maintaining tax fairness, appropriate and moderate levels of penalty, and keeping tax rates as low as possible can all foster taxpayers' voluntary compliance. Fairness in the execution of tax regulations should be enshrined, and tough measures to combat tax revenue corruption should be implemented.

Published: August 2022

This study sought to establish teachers’ reflections on the role of inquiry-based learning in science education. The study was quantitative in nature and used the descriptive research design. Data was gathered through a questionnaire containing closed ended items. Respondents were eighty-two science teachers from secondary schools in Kirehe District.  It is concluded that the choice of appropriate teaching and learning approaches influences understanding in science education. Inquiry-based learning is effective for acquisition of practical skills and development of higher order thinking skills. However, shortage of continuous professional development impedes teachers’ implementation of the inquiry-based learning. The use of inquiry-based learning serves as a promising learning method to enhance learners’ understanding.  It is recommended that school administrators should understand the 5-E model that governs the inquiry-based learning as one of the best teaching and learning approaches and collaborate with teachers to find out means and strategies that may stimulate the implementation of new teaching and learning approaches in science education. School administrators should regularly organize internal workshops and training of teachers on teaching and learning approaches.

Published: August 2022

The purpose of this study was to explore the mothers’ experiences in taking care of schooling children in the context of domestic violence in Songwe Region, Tanzania. The study opted for qualitative approach using the interpretive phenomenological design with a sample of 30 interviewed participants obtained through snowball sampling. The findings show that physical violence against mothers in terms of slapping and punching with fists from husbands made mothers provide inadequate needs and services to children. The results further show that social cultural beliefs and norms that assign men to control the family properties and make decision on family issues are the major underlying root cause of violence against women including wives. It is therefore recommended that deliberate measures should be taken by the government through its respective ministry and NGOs to protect women including mothers against partner violence so as to create harmonious home environments where fathers and mothers should work together in providing essential needs for children.

This study sought to establish the effect of Concept Cartoons on Kindergarten Pupils’ Numeracy and Science Performance at a demonstration primary school in Sagnarigu-Tamale, Ghana using the experimental research design. The population of the study was 100 KG-2 A and B Pupils in the school. A purposive sampling technique was used to select an intact class of 58 pupils that had difficulty in participation and performance in natural science and numeracy. A pre-test was conducted to determine the initial performance of pupils before the intervention that was done through teaching with the support of the concept cartoons. The analysis of the first two objectives involved mean scores and standard deviation. Pre-test and post-test scores were analysed to address the two objectives. The study established that the use of concept cartoons significantly improved the pupils’ achievement in natural science and numeracy lessons. Therefore, the use of concept cartoons as a teaching aid is a powerful approach to improve the performance of pupils in sciences and numeracy. The study recommended that teachers of sciences and numeracy in early primary education ought to use the concept cartoon approach in order to improve the performance of pupils in the su

Published: August 2022

This study aimed at establishing elderly perceptions regarding changes in the parent-child relationship in the Coast region through crossectional design. Both probability and non-probability techniques were used to select the sample. The study managed to collect data from 394 respondents. Data was collected through a questionnaire survey, focus group discussions and key informant interviews. The study findings revealed that older people perceived changes in the parent-children relationship as negative and detrimental. This marks a contrasting difference in the parent-child relationship between the traditional and modern eras. Further, the elderly had a perception that the current generation of adult children has tremendously failed to keep and preserve values, norms, folklore and taboos that used to maintain the parent-child relationship in the past. This has led adult children to lack respect, proper consultation and regular communication with their elderly parents. Modernization and urbanization were perceived as the main causes of changing parent-child relationships in modern days. It is recommended that the government and the community should ensure that traditional norms and values which enforced children’s obedience towards their parents when are old are maintained. Further, the traditional communal parenting system whereby the whole community was responsible for the children's upbringing should be emphasized. Additionally, the community and the government at large should ensure that adult children are taught the importance of the elderly in the community, given their vast wisdom and experience. Moreover, there is a need for the government to collaborate with community leaders to ensure that modernization and urbanization do not alter the norms and values of most Tanzanian societies.
The Use of Conditioning in Behavior Modification
Authors: Thompson-Bramwell Belinda , Mauzard Nicole
Published: August 2022

Behavior modification has been an important topic of discussion in psychology for decades. This topic has generated much interest among parents, educators, marketers, clinicians and others. We all want to understand how to effectively help people to change undesirable behaviors.  Behaviorists have developed a number of theories and have contributed significant insights into how the principles of these theories can be applied to modify behaviors. This paper reviewed three such theories: classical conditioning, operant conditioning, and contiguous conditioning. The articles reviewed suggested that the principles of these theories, when implemented, help to modify behaviors. However, not all can be depended on for lasting effects. Classical and operant conditioning remain effective only with reinforcements. When the reinforcements are removed, the response (behavior) goes extinct. Contiguous conditioning, on the other hand, proposes three approaches to behavior modification which seem to have a longer lasting effect on behavior modification.

Published: August 2022

In this study, phenolic and flavonoid contents of various extracts of Acalypha fimbriata Schum. & Thonn. leaf and stem were determined. The metabolic profile of one extract was studied using GC-MS analysis. The antioxidant activities of the extracts were evaluated using in vitro and in silico studies. Four extracts each of leaf and stem of A. fimbriata have phenolic contents of 0.17 - 0.29 and 0.15 - 0.29 mg gallic acid equivalent/g extract, respectively. The leaf extracts have flavonoid content of 0.13 - 0.40 mg quercetin equivalent (QE)/g extract, which was slightly higher than that of the stem (0.18 - 0.33 mg QE/g extract). Extracts of the stem (IC50 range 50.82 - 62.94 μg/ml) showed greater DPPH radical scavenging activity than those of the leaves (IC50 range 61.03 - 82.24 μg/ml). All the extracts (except the ethyl acetate and aqueous extracts of the leaf) demonstrated significant NO• radical scavenging activities, which were comparable (p > 0.05) to that of ascorbic acid. The extracts of the leaf and stem displayed lower reducing powers (0.07 - 0.56 and 0.09 - 0.50, respectively) compared to ascorbic acid (0.16 - 0.63) and showed considerable total antioxidant capacity values of 0.27 - 0.55 and 0.36 - 0.54 mg ascorbic acid equivalent/g extract, respectively. Some metabolites, including preg-4-en-3-one-17α-hydroxyl-17β-cyano, salirepin hexaacetate, eugenol and squalene were identified in one of the extracts. These metabolites gave good binding affinities against cytochrome P450, lipoxygenase, myeloperoxidase, NADPH oxidase and xanthine oxidase, indicating good antioxidant potentials. This study reveals that extracts of A. fimbriata possess broad spectrum of antioxidant activity and could be exploited as sources of antioxidant constituents to manage oxidative stress.

Published: August 2022

Service delivery is simply the act of providing service to users, customers, or clients. It is a component of activities that defines the interaction between providers (librarians) and clients (users). Leadership is the influencing process of leaders and followers to achieve organizational objectives through change. Influencing in leadership is about the relationship between leaders and followers, it does not necessarily mean control is enforced on the followers. This paper discussed effective leadership as the roadmap toward academic librarians‟ service delivery. A general overview was explained of what leadership is, looking at the leadership styles that leaders of academic libraries and others alike may employ to carry out their daily activities to ensure service delivery. This paper also described the effectiveness of leadership for service delivery which showcases the ability of the individual to successfully direct the activities of the group of librarians to the attainment of stated goals and objectives. The role of leadership in academic libraries in service delivery was expatiated. The conclusion of this work stated that leadership is a function of group association and interaction. It was recommended among others that there should be effective leadership in the library so as to bring about good service delivery and information dissemination to the library users.

Published: August 2022

In June 2018, iCog Labs held its second annual robosoccer competition which featured groups of humanoid robots playing soccer against each other. The authors were members of a team called upon to represent Nigeria with the University of Lagos at the competition which took place in Ethiopia. The work here presents a review of the approach taken to address the problem of automating robot coordination in real-world soccer applications. The design methodology relies on the Robot Operating System (ROS) as the platform upon which an asynchronous communication network between each robot and a central server is built. On the network, each robot is a node that consists of sub nodes for object detection and motion control. For object detection the work makes use of the you only look once (YOLO)v2 deep learning algorithm, and a simple decision-making algorithm for controlling vcv the robot based on the objects detected is devised. To quantify the object detection results, the common objects in context (COCO) evaluation metric is used. The results indicate an average recall and precision of 84% across different IOU. For qualitative results on the robot coordination in the ball’s direction, a reference to the open-source implementation of the work has been provided.

Published: August 2022

Carcinogenic effects and other harmful effects associated with low dose-rate and low dose radiation have recently been reported. Therefore, it is important to identify effective and safe radioprotectors or radiation mitigators that can counter the effects of ionizing radiation damage. Therefore, the aim of the study was to evaluate the mitigating potential of methanolic leaves extract of Duranta erecta (DE) against acute whole-body X-ray irradiation-induced oxidative stress in Wistar albino rats. Rats in groups B, C and D, were exposed to double X-rays radiation at a source to skin distance (SSD) of 70 cm to deliver a total radiation dose of 18.4mGy at the rate of 9.2mGy/exposure using 100kVp and 30mAs exposure factors and quality factor of the X-ray machine (P) of 15. Rats in group A (control) were neither irradiated nor administered with DE extract. In contrast, group B rats were irradiated but not treated. DE extract at doses of 500 and 1000 mg/kg body weight was administered to groups C and D rats for 15 consecutive days. On post-irradiation days 1, 7, 14 and 21, the antioxidant status of the rats was evaluated and compared with control. Parameters assessed were catalase (CAT), superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA). Mean serum levels of GSH, SOD, CAT and MDA in the irradiated and treated groups did not vary significantly (P > 0.05) from the un-irradiated control group. In conclusion, methanolic extract of DE mitigated against radiation-induced decline in serum GSH, SOD, CAT, and radiation-induced MDA elevation. Results obtained indicated that methanolic extract of DE can be used potentially as a natural radiation mitigating agent.

Vaccines are one of the most effective and successful strategies employed to date to prevent and increase the population's immunity against several viral diseases. However, vaccine hesitancy among populations poses a potential danger to global health. This study focused on determining the vaccine acceptance rate and associated key determinants among veterinarians. A cross-sectional study using a web-based survey among veterinarians was conducted in the month of April 2021. A multivariate logistic regression model was performed to identify key predictors for vaccine acceptance among veterinarians. A total of 305 veterinarians participated in this survey, of whom 39 respondents (12.8%) had received the COVID-19 vaccine. The vaccine acceptance rate among respondents was 38.3% (excluding those that have taken the vaccine). Only 37.0 % of the respondents were confident about the safety and efficacy of the Oxford–AstraZeneca vaccine in circulation in the country. Major perceived drivers for vaccine acceptability were safety (91.8%), possible adverse reactions (85.6%) and global acceptability (75.7%). The adjusted odds ratio (aOR) of vaccine acceptance increased by 2.3 times among male veterinarians than females (95% CI: 1.358-3.900; p = 0.002) in the multivariate model. In Nigeria, little is known about COVID-19 vaccine acceptance (VA) and predictors among animal healthcare providers, including veterinarians. The study found gender as a key sociodemographic predictor for VA. There is a need to address the sociodemographic determinants of vaccine hesitancy through public health efforts and increase COVID-19 vaccine acceptance and coverage in Nigeria.

In Burkina Faso, beekeeping is practised throughout the country. It has many potentialities, but it faced many constraints. Sanitary constraints are less investigated and need to be elucidate for a better management of bee colonies and improvement of beekeeping. A descriptive study was conducted in Cascades region to assess the prevalence and the density of Varroa mite infestation. The method of sugar shake on adult bees was used. The overall prevalence found was 91.7% [95% CI: 83.8% - 99.5%] and the density varied from 0.3 mite/100 bees to 12.3 mites/100 bees. These results show that the Varroa mite is widespread in bee colonies and its monitoring should be considered for bee health management, which is essential for sustainable beekeeping. Advanced research is needed in a large sample area to further investigate the epidemiological aspects and the potential impact of the mite on honeybee production.
Chern currents of coherent sheaves
Authors: Lärkäng Richard , Wulcan Elizabeth
Published: August 2022

Given a finite locally free resolution of a coherent analytic sheaf $\mathcal F$, equipped with Hermitian metrics and connections, we construct an explicit current, obtained as the limit of certain smooth Chern forms of $\mathcal F$, that represents the Chern class of $\mathcal F$ and has support on the support of $\mathcal F$. If the connections are $(1,0)$-connections and $\mathcal F$ has pure dimension, then the first nontrivial component of this Chern current coincides with (a constant times) the fundamental cycle of $\mathcal F$. The proof of this goes through a generalized Poincar\'e-Lelong formula, previously obtained by the authors, and a result that relates the Chern current to the residue current associated with the locally free resolution.

A Coalgebraic Approach to Dualities for Neighborhood Frames
Authors: Bezhanishvili Guram , Bezhanishvili Nick , de Groot Jim
Published: August 2022

We develop a uniform coalgebraic approach to J\'onsson-Tarski and Thomason
type dualities for various classes of neighborhood frames and neighborhood
algebras. In the first part of the paper we construct an endofunctor on the
category of complete and atomic Boolean algebras that is dual to the double
powerset functor on $\mathsf{Set}$. This allows us to show that Thomason
duality for neighborhood frames can be viewed as an algebra-coalgebra duality.
We generalize this approach to any class of algebras for an endofunctor
presented by one-step axioms in the language of infinitary modal logic. As a
consequence, we obtain a uniform approach to dualities for various classes of
neighborhood frames, including monotone neighborhood frames, pretopological
spaces, and topological spaces.
In the second part of the paper we develop a coalgebraic approach to
J\'{o}nsson-Tarski duality for neighborhood algebras and descriptive
neighborhood frames. We introduce an analogue of the Vietoris endofunctor on
the category of Stone spaces and show that descriptive neighborhood frames are
isomorphic to coalgebras for this endofunctor. This allows us to obtain a
coalgebraic proof of the duality between descriptive neighborhood frames and
neighborhood algebras. Using one-step axioms in the language of finitary modal
logic, we restrict this duality to other classes of neighborhood algebras
studied in the literature, including monotone modal algebras and contingency
algebras.
We conclude the paper by connecting the two types of dualities via canonical
extensions, and discuss when these extensions are functorial.

Published: August 2022

The Mantaro River travels through Junín, Ayacucho, and Huancavelica departments,in Peru, and receives not only domestic discharges from the population but also tailings fields and dumps containing lead, silver, copper, and zinc from mining companies. To be able to assess the water quality, the grey clustering method was applied, using Center-point Triangular Whitenization Weight Functions (CTWF) for this purpose. As well, Pearson correlation between parameters was used to understand the dynamics of pollution. In the watershed of the Mantaro river the results of the Monitoring of the Surface Water published in 2018 by the Mantaro Water Administrative Authority were compared to the Peruvian Environmental Quality Standards (ECA) Category 1, subcategory A parameters. The results obtained suggest that the main driver of pollution in the Mantaro river is not mining, but domestic waste in landfills and probably agriculture. Finally, this study shows responsible environmental management by mining companies, besides, could be helpful for regional and local authorities of Peru in making decisions to improve the management of the Mantaro river watershed and make the population aware of the sustainable use of water

Published: August 2022

Researchers in robotics and computer vision are experimenting with the image-based localization of indoor cameras. Implementation of indoor camera localization problems using a Convolutional neural network (CNN) or Recurrent neural network (RNN) is more challenging from a large image dataset because of the internal structure of CNN or RNN. We can choose a preferable CNN or RNN variant based on the problem type and size of the dataset. CNN is the most flexible method for implementing indoor localization problems. Despite CNN's suitability for hyper-parameter selection, it requires a lot of training images to achieve high accuracy. In addition, overfitting leads to a decrease in accuracy. Introduce RNN, which accurately keeps input images in internal memory to solve these problems. Longshort-term memory (LSTM), Bi-directional LSTM (BiLSTM), and Gated recurrent unit (GRU) are three variants of RNN. We may choose the most appropriate RNN variation based on the problem type and dataset. In this study, we can recommend which variant is effective for training more speedily and which variant produces more accurate results. Vanishing gradient issues also affect RNNs, making it difficult to learn more data. Overcome the gradient vanishing problem by utilizing LSTM. The BiLSTM is an advanced version of the LSTM and is capable of higher performance than the LSTM. A more advanced RNN variant is GRU which is computationally more efficient than an LSTM. In this study, we explore a variety of recurring units for localizing indoor cameras. Our focus is on more powerful recurrent units like LSTM, BiLSTM, and GRU. Using the Microsoft 7-Scenes and InteriorNet datasets, we evaluate the performance of LSTM, BiLSTM, and GRU. Our experiment has shown that the BiLSTM is more efficient in accuracy than the LSTM and GRU. We also observed that the GRU is faster than LSTM and BiLSTM

Published: August 2022

Emotions are essential in interpreting the actions and relations of people. Nowadays, EEG signals are commonly used in emotion realization, so neurologists and psychiatrists can use a brain-computer interface to diagnose and cure emotional disorders. Another benefit of the BCI system is recognizing emotions without a clinical exam. A significant issue in automatic emotion realization is the appropriate extraction and selection of features. This paper aims to develop a state-of-the-art method to automatically classify four types of emotions from PSD and DE features. Features are fed to a convolutional neural network and long short-term memory network (CNN-LSTM). The 1DCNN network has been combined with the LSTM network to get a more stable system. The accuracy of subject-independent emotion realization with PSD and DE features is 84% and 93%, respectively. We have also compared our proposed CNN-LSTM model with other deep learning models. Our results are promising compared to similar approaches and have a better F1 score value. The experimental results also show that human emotions are better recognized by beta and gamma band

Nos últimos anos, com a intensificação do processo de globalização e o avanço de novas tecnologias, ocorreram transformações nas dinâmicas e cadeias produtivas, permitindo que alguns autores afirmassem a mudança de uma sociedade industrial para sociedade do conhecimento (CASTELLS, 1999). Neste contexto, que a busca pelo avanço da tecnologia passou a fomentar o mercado capitalista, ocasionando na competitividade de empresas entre diferentes escalas geográficas (local, regional, nacional e global). É nesta perspectiva que surgem os parques tecnológicos, com o objetivo de fomentar a criação de ambientes inovadores, visando à produção e difusão da inovação, seja ela de base tecnológica, com novos produtos e processos, ou de marketing e organizacional, entre outras. No Brasil, com os programas de incentivo à inovação e criação de parques tecnológicos, atualmente há 103 iniciativas (MCTI, 2019), tendo sua concentração no estado de São Paulo. Este artigo tem como objetivo compreender a espacialização dos parques tecnológicos no estado de São Paulo, destacando o papel das redes técnicas, enquanto condições gerais de produção favoráveis à sua implantação, a metodologia utilizada neste estudo pautou-se em pesquisa bibliográfica, documental, com coleta de dados no IBGE (Instituto Brasileiro de Geografia e Estatística) e MCTI (Ministério da Ciência, Tecnologia e Inovações).

The article analyzes the questions related to the service packaging, which is performed in the function of realization of the process of selling a product, as well as those concerning packaging and requirements that must be satisfied with regard to its composition, reusability and reproducibility. The packaging rules, packaging obligations that are used for packaging, have been shaped by the participants themselves and are applied as a customary commercial practice. Rules on packaging composition, reusability and reproducibility are part of a group of modern rules, which are given special attention through the adoption of regulations, among which is the new Directive 2018/852/EU. That directive pointed out the need to prevent the creation of packaging waste, the measures that should be taken to that end, while defining the deadlines within which it is necessary to achieve a certain level of recycling of packaging waste in relation to the total quantity of waste and type of packaging material.

Almost all the services which are available today in a modern society were also known to the ancient Romans. Among others are the laundary and dry cleaning services. We are not claiming here that dry cleaning existed then in the same form that has been adopted in modern times, but certainly there were laundery workers called fullo, nis who worked in laundary shops called Fullonica (Fullonicum) in which specific forms of clothes cleaning and whitening were performed, as well as the services of finishing fabric by rolling and scrubbing it to remove imperfections from spinning and weaving. We learn about fullo's activities from the scripts of ancient historians, but also a significant part of the Code of Justinian, the Digest, was dedicated to the rules governing thier activity. There we can find that this kind of services was always charged and that fullo even had their association called collegium. The information related to the fees charged for this activity can be found in Diocletian's Price Edict defining the maximum prices of services (Edictum de pretiis rerum venalium). Thus, for example, the Section 7 of the Edict includes the rates of 76 different types of services of various workers and craftsmen, but not the rate for laundary services. However, the Section 22 of the Edict is entirely dedicated to these services which emphasized the importance of this profession in ancient Rome. The most famous laundary shop was in in Pompeii, called Fullery of Stephanus.

In this paper the author points to the essential role of providing intellectual services in all fields of activities, given the fact that there is a generally spread paradox “to know everything is to know nothing”. Namely, we live in times when people specialize to perform only certain segments of work, which they execute to perfection. Therefore, in order to avoid mistakes in certain fields one does not know much about, the companies decide to look for certain intellectual cervices. When it comes to the field of insurance, the brokers have become the essential part of the contemporary insurance business and its success is directly connected to their success in providing services. Recently, there has been a growing number of individuals offering such services which resulted in a need to regulate this field, bringing it within legal framework of the Insurance Law. Not only in Serbia, but also in Republic of Srpska this matter has been given a considerable attention, so this entity adopted Law on insurance intermediaries 10 years before Serbia.

The social value of sport is expressed through the various roles that sport has, or should be, in the life of a particular individual or community. Accordingly, the social functions of sport should be subordinated to noble goals in order to achieve individual as well as collective benefits. Nevertheless, the history of social relations has shown that almost everything that a man has created for his own well-being can be the object of his abuse. In this sense, sport is no exception. Therefore, the consideration of the social value of sports implies an attempt to see the relationship between the positive and negative sides of this exceptional social phenomenon.
