Published: February 2024

We propose and study a new generalized class of distributions called the Type II Exponentiated Half Logistic-Gompertz-G Power Series (TIIEHL-Gom-GPS) distribution. Some structural properties including expansion of density,ordinary and conditional moments, generating function, order statistics and entropy are derived. We present some specialcases of the proposed distribution. The maximum likelihood method is used for estimating the model parameters. Theimportance of the new class of distributions are illustrated by means of two applications to real data sets.
Using transfer adaptation method for dynamic features expansion in multi-label deep neural network for recommender systems
Authors: Abdullayeva Fargana , Suleymanzade Suleyman
Published: February 2024

In this paper, we propose to use a convertible deep neural network (DNN) model with a transfer adaptation mechanism to deal with varying input and output numbers of neurons. The flexible DNN model serves as a multi-label classifier for the recommender system as part of the retrieval systems’ push mechanism, which learns the combination of tabular features and proposes the number of discrete offers (targets). Our retrieval system uses the transfer adaptation, mechanism, when the number of features changes, it replaces the input layer of the neural network then freezes all gradients on the following layers, trains only replaced layer, and unfreezes the entire model. The experiments show that using the transfer adaptation technique impacts stable loss decreasing and learning speed during the training process.

‘Nothing new under the sun’
Authors: Ruch Gillian
Published: February 2024

The post-qualification social work context is undergoing enormous change. What remains clear amidst the turmoil, is that the delivery of the new programmes will be to groups of social work practitioners with varying degrees of interest in, ambivalence about or resistance to engaging in further professional development This paper explores the use of sculpting, a creative technique that originated in family therapy as a means of countering some of the resistance to learning that can characterise such groups. Encouraging practitioners to explore ‘embodied understandings’ of families with whom they work or group contexts in which they find themselves has the potential to offer holistic, anti-oppressive and energising learning opportunities.
Strengths-based groupwork with alcohol dependent older persons
Authors: Geyer Stephan
Published: February 2024

Worldwide the numbers of older people in the population are increasing. Simultaneously the need for treatment programmes increases as more alcohol dependent people are growing into old age. Literature reviews revealed that groupwork programmes offered to older persons are exclusively problem-centred, while strengths-based scholars suggest that following a strengths perspective may be more effective. The majority of studies tend to evaluate the outcomes of treatment programmes quantitatively. It was also found that South Africa, which adopted a developmental approach towards social welfare, lacks groupwork programmes specifically designed for alcohol dependent older persons. This article reports on the outcomes of a strengths-based groupwork programme for alcohol dependent older persons. The programme is unique in the sense that it is based on a strengths perspective; it is reconcilable with South Africa’s welfare approach; and follows a mixed methods research approach in order to evaluate the programme holistically. Eight respondents were randomly selected. The results, collected with a group administered questionnaire, show that the respondents’ psychosocial functioning improved, in that: their repertoire of strengths increased and they have achieved, or are on a path towards, ego integrity. This programme is considered to be complementary to current treatment programmes.

Authors: Singh Penny , Niranjan Ivan
Published: February 2024

Abstract: In order to ensure the safety and health of workers, Occupational Health and Safety practitioners must have an excellent understanding of the Occupational Health and Safety Act and Regulations. They must therefore be able to interpret statutes and legislation which ensure that all sorts of work activities are carried out safely and with minimal risk. The aim of this study was to determine the effectiveness of the designing and playing of the board games as an educational intervention in Occupational Health and Safety within a groupwork context in a diverse classroom at a tertiary institution in South Africa, and report on students’ reflections of the process. Using groupwork, the boardgame exercise proved to be an effective teaching methodology and deep learning was achieved by designing, playing, and being assessed on the games. The use of groupwork also promoted improved relations and interactions, and effective teamwork. Valuable lessons in communication, collaboration and conflict resolution were also learned.
Use of social media by self-help and mutual aid groups
Authors: Boyce Melanie , Seebohm Patience , Chaudhary Sarah , Munn-Giddings Carol , Avis Mark
Published: February 2024

This paper explores the use of social media by self-help/mutual aid groups that meet on a regular face-to-face basis. It draws on data from the ESTEEM project, which ran from 2010 to 2013 with the overall aim of developing a range of resources for health and social care practitioners on how to support self-help/mutual aid groups. A re-examination of the interviews and discussions that were undertaken with 21 groups in two UK sites indicated that groups’ use of social media was becoming an increasingly important resource. The findings highlight a range of benefits and limitations with selfhelp/mutual aid groups using social media and suggest a blurring of boundaries between online and face-to-face groups. For groupworkers involved with self-help/mutual aid groups opportunities in developing groups’ online presence are raised.
Therapeutic factors in expressive art therapy for persons with eating disorders
Authors: Sporild Inge Anne , Bonsaksen Tore
Published: February 2024

Abstract: Group therapy has been widely discussed in terms of factors that work. Most of the previous work in this field is related to verbal psychotherapy, but it should not be assumed that non-verbal, activity-based groups, as well as combined group forms, have the same operating mechanisms as verbal psychotherapy groups. Thus, there is a need for more knowledge concerning the therapeutic mechanisms that other types of groups rely on. This article describes and discusses the expressive art therapy group at an eating disorders unit in Norway. Particular emphasis is placed on linking specific elements of a case example to a framework for describing therapeutic factors in groups.
Strengths-based group supervision with social work students
Authors: Alschuler Mari , Silver Thelma , McArdle Linda
Published: February 2024

This paper integrates the theoretical models of the strengths perspective with narrative theory and reflective practice, while incorporating the concepts of parallel process and the Socratic method into the group supervision of social work students. With the strengths perspective as a unifying model in social work today, it is suggested that this model also can reflect the supervisory parallel process. Thus, just as we strive to work with clients in a cooperative partnership that emphasizes their strengths and abilities, empowerment, resilience, and diversity, so, too, we need to bring these concepts into the supervisee-supervisor relationship.

Authors: Saliu Mojeed Olanrewaju
Published: February 2024

This research work examines the impacts of foreign aids and human capital on economic growth of African oil and non-oil producing countries. Adopting the time series data from 2000 to 2021, the study employs Westerlund Error Correction Based panel cointegration test to investigate the impacts of Physical Capital (FA, GCF, FDI), Human Capital (EDU, HLT) and Policy Variables (REV, EXR) on Gross Domestic Product growth rate (GDPgr). Findings from results of the study affirms that there is a long-term co-movement between the GDPgr and the explanatory variables (FA, GCF, FDI, EDU, HLT, REV, EXR) of both African oil and non-oil producing countries. The study also reveals that foreign aids are better effectively put into use in the African non-oil producing countries than in the oil producing countries. Findings in the study equally confirm that financial resources in the African non-oil producing countries are better efficiently spent on human capital and domestic investment than in the African oil producing countries. The study further shows that revenue generation and foreign exchange earnings stimulate growth better in the African oil producing countries than the non-oil countries counterparts in Africa.
Reviewers should not destructively assume the role of a researcher
Authors: Diko Mlamli
Published: February 2024

It cannot be nullified that the peer review process is characterized by reviewers who tend to destructively assume the role of researchers. In so doing, this behavior undermines the intellectual ability of researchers, especially novice researchers, who dedicate their time attempting to contribute to scholarly epistemology. Effectively, this concerning behavior of assuming the role of a researcher may denote that the reviewers downplay the reality that researchers certainly know something; no matter how little or greater it is. Thus, it cannot be fair-minded for reviewers to regard themselves as if they are gods of knowledge. With this in mind, this particular paper aims to explore and open a dialogue concerning the challenge of reviewers who destructively assume the role of an author or researcher, thereupon sabotaging the peer review process by imposing their personal scholarly interests. This is against the reality that such conduct may deter potential epistemologies that may potentially make a constructive social impact within and outside the arena of scholarship. In parallel, such behavior from the reviewers may lead to the rejection of scholarly contributions that can generate change in the academic community. By the same token, the rejection of papers, in large part, by the recommendations of destructive reviewers who assume researchers’ roles may demoralize novice researchers who have a strong determination to construct and assemble original, and innovative insights into the body of knowledge. In view of this fact, reviewers ought to appreciate the importance of recognizing the voices and narratives of the authors without imposing their personal interests that may compromise the quality and publication of valuable and well-deserving scholarly papers. On account of this, I conclude this scholarly dialogue by presenting some of the recommendations that may be considered to mitigate the problematized phenomenon.
Procurement hurdles: unveiling challenges in the subsidized commuter bus sector of Gauteng, South Africa
Authors: Ngcamphalala Thobeka KT , Ambe Intaher Marcus
Published: February 2024

In South Africa, like many developing countries, procurement is seen and used as a strategic tool to promote socioeconomic development, including the promotion of competition, among other objectives. The South African commuter bus industry is structured to procure – through competitive tendering – SMMEs within the industry’s mainstream. These contracts are subsidized by the government – their origins date back to the 1940s – to ease the financial burden on black African communities. However, since its establishment, some challenges are hindering the effective procurement of these services, thus affecting the provision of these services. This paper highlights the challenges faced by Gauteng Province in the procurement of subsidised commuter services. The paper employs a mixed-methods research approach, and the research instrument was a face-to-face semi-structured interview questionnaire. Based on the findings of the study, Gauteng commuter bus industry operations are challenged with poor policy implementation, a lack of funds to support the industry’s operational needs, and a deficiency in administrative skills, among other challenges. The paper recommends that the Gauteng government revisit the guiding policies for the establishment of the industry and employ the best procurement practice(s) for this industry, considering the complex nature of South Africa (being influenced by the apartheid era and the government is faced with maintaining a balance between the blacks and the whites among citizens).
Application of Explainable Artificial Intelligence technique to model the predictors of South African SMMEs resilient performance during the Covid-19 pandemic
Authors: Zhou Helper , Chamba Lucy T , Zondo Robert. W. D
Published: February 2024

Various studies have been carried out to establish the key drivers impacting small enterprise sustainable performance in developing countries. Despite many policy-oriented studies to uncover the factors influencing SME resilience in emerging markets, these firms continue to register high failure rate, which has been further exacerbated by the Covid-19 pandemic. Guided by a history of linear- and log-linear econometric model estimation that ignores potential network effects, our study extends the literature by implicating SMME resilience as a production network. Utilising data from both incubated and non-incubated SMMEs, marking a departure from traditional linear econometric models, radial basis function artificial neural network algorithm was invoked to establish the drivers of SMME resilience during Covid-19 regime. The study extends the literature by implicating eXplainable Artificial Intelligence (XAI) methods. Specifically, optimal SHapley Additive Explanations values (SHAP values) were computed to enhance the prediction output from the machine learning algorithm. The XAI analytics provide insightful findings on the key drivers which influenced the resilience of SMMEs during the Covid-19 pandemic. The importance of innovation through introduction of new products, company age and higher number of marketing mediums is confirmed however total assets, analytics, educational level and number of workers surfaced as a threat to these enterprises’ sustainable performance. The study recommends that both the government and SMEs should leverage XAI to identify their heterogeneous attributes and inform intelligent decision-making which necessities their resilient performance.

The development of small businesses as the basis of the people's economy is one of the strategic steps that need to be followed up with concrete steps to increase family productivity, improve the economy, and overcome the problems of poverty, and unemployment. Community business is one of the strengthening of the local economy. This research is field research with qualitative and quantitative approaches to provide a comprehensive explanation.  The research sample was MSME business actors in Sukajadi Village, Muaraenim Regency using the purposive sampling method. Data collection techniques are used through surveys, documentation, and questionnaires using Likert scales to assess instruments.  Multiple linear regression equations were utilized for the analysis of the data. The results showed that the variables of innovation, competitiveness, and business ecosystem partially or simultaneously affect the strengthening of the local economy. The independent variable affected the dependent variable by 51.2% while the remaining 48.8% was influenced by other variables not described in this study. Innovation, competitiveness, and business ecosystems play a crucial role in strengthening the local economy. These factors are interconnected and have a positive impact simultaneously and reinforce each other. By working together, innovation, competitiveness, and business ecosystems can create a strong sustainable, and inclusive local economic environment at the local level. This not only benefits local businesses but also for communities to become more resilient and able to access more opportunities. This condition supports the improvement of the welfare and quality of life of the community as a whole.
Realizing potential: a real option perspective on communities of practice in organizational transformation
Authors: Wang Tz-Li
Published: February 2024

This research aims to explore the recognized advantages of Communities of Practice (CoPs) in enhancing knowledge sharing and spurring organizational transformation. Despite their acknowledged importance, CoPs often receive inadequate attention or representation in numerous organizations, likely due to leaders' unfamiliarity or insufficient skills to manage such groups. This study introduces the "Real Option Perspective" as the recommended approach for top executives to understand and leverage CoPs. Initially, it clarifies the concepts of CoPs and the Real Option Perspective, highlighting their significance. These concepts then lay the groundwork for developing a management model for CoPs. The proposed management trajectory for CoPs involves five phases: Investment in CoPs, Recognition of Stagnation, Re-engagement with CoPs, Transition of Value, and finally, Dissolution and Feedback. This research seeks to expand the applicability of the Real Options framework in managing CoPs, providing leaders with strategic insights to fully realize the potential of CoPs in line with organizational objectives.

Authors: Gunawan Arie Indra , Dewi Andrieta Shintia , Azis Elvira
Published: February 2024

This paper aims to contribute to a better understanding of the relatively comprehensive breadth of information on outsourcing-offshoring from existing and open-source research articles. A systematic literature review was carried out on 700 articles related to global outsourcing to obtain results of scientific studies. The PRISMA method is used to get relevant articles that meet the quality control aspects of the article data used. Research on global outsourcing and offshoring showed significant progress from the start until its peak in 2008. In 2000 global outsourcing was in the implementation stage, requiring a lot of basic and conceptual research to develop global outsourcing activities. After 2008 the topic of global outsourcing research studies decreased. This was because research on global outsourcing became more specific. The 32 topic items grouped into 4 clusters are state-of-the-art research on global outsourcing-offshoring topics in the last 20 years.
Shockwaves in consumer minds: The thunderous role of media in sculpting brand popularity
Authors: Fitrianna Hafizh
Published: February 2024

This study explores the complex relationship between brand popularity, media exposure, curiosity, fear of missing out, and consumers’ information-seeking behaviour on digital platforms. Negative and controversial news sometimes actually makes a brand increase in popularity. This phenomenon is known as the Streisand Effect. With a sample of 358 smartphone users in Indonesia, and utilizing a theory of planned behaviour (TPB) approach, we analyze how digital news content influences consumers’ perceptions and behaviour towards brands, primarily through increased information-seeking behaviour. Partial-Least-Squares Structural Equation Modelling and Importance-Performance Analysis (IMPA) were used to analyze the data. Our findings show a significant correlation between information-seeking behaviour and brand popularity, underscoring the impact of digital news content in shaping individual preferences and behaviours. Positive news, negative news, and controversial news, respectively, have different influences on each relationship. This research contributes to a deeper understanding of the role of media in brand management and offers insights for marketers looking to utilize digital platforms for brand enhancement. Future research could expand our study with additional variables.
Fabrication Methods of the Polygonal Masonry of Large Tightly-fitted Stone Blocks with Curved Surface Interfaces in Megalithic Structures of Peru
Authors: Lapshin Rostislav
Published: February 2024

The article suggests methods that allow creating the most complicated type of polygonal masonry existing in Peru. This masonry type consists of large stone blocks weighing from several hundred kilograms to several tons fitted close to each other almost without a gap between complicated curved surfaces over a large area. The work provides a description of techniques, which apparently were used by builders who arrived from Europe. The techniques under discussion are based on the use of a reduced clay model, 3D-pantograph, topography translator and replicas. The use of the topography translator, reduced clay model and pantograph provides not only the unique appearance and high quality of the masonry of large blocks, but also allows to increase productivity of the builders significantly. As mechanisms for coping-scaling three-dimensional objects are known since the beginning of the 18th century, the stone structures under consideration should be approximately dated by this time. The remaining simpler types of the polygonal masonry, when the stones are small or the fitted surfaces are almost flat, or the stones contact each other over a small area, or there are significant gaps between the stones, are quite consistent with the well-known methods of stone processing at that or earlier time and, therefore, they do not require any additional explanations. The Fortress Sacsayhuaman is considered as an example of early star fortresses that has survived to our time. The polygonal structures in Peru, the polygonal Face Towers and polygonal bas-reliefs in Cambodia, the symmetrical statues of pharaohs in Egypt are based on the same construction technologies, working methods, tools and technical contrivances. Therefore, with a high probability one can state that all these monuments were created by the same group of architects, sculptors, builders and could not have appeared before the 17th century.

The compressive strength for cubes and cylinder with carbon fibers is the highest as compare to steel fibers as well as glass fibers. The compressive strength of concrete is measured on 3 day, 7 day, 14 day and 28 day strength. The compressive strength of cube on 28th day strength is 37.52 MPa for carbon fiber steel, for steel fiber it is 34.22 MPa and with glass fiber the strength is 29.335 MPa whereas the compressive strength of cylinder with carbon fibers the 34.88 MPa, with steel fiber it is 34.22 MPa and with glass fiber the strength is 27.447 MPa. For the cubes the maximum difference between different fibers inducted concrete sample is 28% approximately and for cylinder it is 27%, respectively. On the other hand, the tensile strength of concrete was also gained with the carbon fiber. It was determined that carbon fiber provided about 16% and 12.8% tensile strength higher than glass and steel fibers respectively.

The production of biomass fly ash has been increasing every year in Europe, reaching 5.5 million tons in 2020. Biomass fly ash is not yet accepted in the standards as a substitute material for cement in mortar and concrete. In a first approach, the substitution limit of biomass fly ash is determined by comparing the mechanical strengths, fresh state properties and hardened properties of mortars produced with biomass fly ash to those of mortars produced with classical coal fly ash. Then, masonry and rendering mortars have been designed with different substitution rates of biomass fly ashes from wood combustion in thermal power plant. Although there is an overall decrease in performance, mortars made with biomass ash retain properties that make them suitable for use in masonry or rendering.

This study investigated the effects of exogenous gibberellic acid (GA) treatments (elongating cluster + seedless + expanding, T1; seedless + expanding, T2; expanding, T3 and water, CK) on the content of sugars, organic acids, and endogenous hormones and sink strength.Results showed that T2 treatment displayed the highest fructose and glucose levels at 100 days after treatment (DAT), whereas its effect on tartaric acid, malic acid, and citric acid concentrations at 80 and 100 DAT was relatively weak. Under GA3 treatments, both GA3, IAA, and CTK contents increased, whereas ABA contents decreased at 1, 2, 4, 8, and 48 h. Analysis of sugar phloem unloading revealed that T2 treatment exhibited the highest values during softening and ripening stages. Our findings indicate that appropriate GA3 application can positively influence sink strength by regulating sink size and activity, including berry size enlargement, sugar phloem unloading and sugar accumulation in grape sink cells.
Numerical integration of one-dimensioned parabolic problems using adaptive grids
Authors: Bulatov Pavel Evgenyevich
Published: February 2024

A method of numerical integration of one-dimensioned parabolic initial boundary value problems with contrast structures using movable adaptive grids is described. A difference scheme which is resistant to machine rounding errors and time-monotonic is constructed. Algorithms for constructing adaptive grids in space and time are proposed. A series of numerical experiments using the example of a singularly perturbed “reaction-diffusion-advection” problem is provided.

Background:

Various studies have examined the risk of peroneal nerve injury with use of standard magnetic resonance imaging (MRI) of the knee. However, the position of the knee during standard MRI is different from that during an actual arthroscopic lateral meniscal repair. The purpose of the present study was to evaluate and compare the risk of peroneal nerve injury during simulated all-inside lateral meniscal repairs on the basis of MRI scans made with the knee in both positions.

Methods:

With use of axial MRI scans made with the knee in the standard position (i.e., in 30° of flexion) and in the actual position used during arthroscopic lateral meniscal repair (i.e., in a figure-of-4 position), direct lines were drawn to simulate the passage of a straight all-inside meniscal repair device from the anteromedial and anterolateral portals to the medial and lateral borders of the popliteus tendon. The distance from the closest passage of each line to the peroneal nerve was measured. If a line touched or passed through the peroneal nerve, a risk of iatrogenic injury was noted and a new line was drawn from the same portal to the outer border of the peroneal nerve. The danger area was measured from the first line to the new line along the joint capsule.

Results:

In 28 Thai patients, the shortest distances from each line to the peroneal nerve were significantly shorter on the MRI scans made with the knee in the standard position than on those made with the knee in the arthroscopic position (p < 0.05 for all). All danger areas on the MRI scans that were made with the knee in the arthroscopic position were included within the danger areas on the scans that were made with the knee in the standard position.

Conclusions:

Standard MRI scans of the knee can be used to determine the risk of peroneal nerve injury at the time of arthroscopic lateral meniscal repair, although the risks are slightly overestimated.

Published: February 2024

The research was conducted to analyze the level of students critical thinking skills and and the requirements for implementing PBL using android modules to improve students critical thinking skills in physics. This research method was included in the preliminary research with a sample of 174 students in XI grade MIPA at Gresik State High School. Data collection is done by sharing critical thinking tests with students, conducting questionnaires for students, and conducting teacher interviews. The data is examined both qualitatively and descriptively to explain the research's findings. The results of this research showed that 1) many students still had a low level of critical thinking. Of the 174 students, 119 have low level, 44 have medium level, and 10 have high level. The evaluation indicator has the lowest average value, and the interpretation indicator has the highest average. Student critical thinking skills are higher for females than for males. The conclusion is that the skills to think critically is very important during learning, especially in physics. To improve the critical thinking skills of students, the way that can be done is by applying PBL-assisted android modules.
