The judge as the main element in the court places his profession as a representative of God, because the judge's job is to determine law and justice in society, so the responsibility he bears is very heavy but noble. Therefore, the profession of judges has such great power, that judges are required to balance an attitude that is full of responsibility to conscience and ethical values towards their profession. However, if you look at the current reality, there has been a decline in the quality of judges not only in their decisions but also in regards to a decrease in the moral aspect. The research method used in this study is a normative method with a conceptual approach and a statutory approach. The results of this study are that judges must be able to embody ethical and moral values as formulated in the code of ethics for the profession of judges, namely by exploring the sense of justice held by society. With an ethical and moral foundation through the professional code of ethics of judges, judges will realize fair law enforcement.Keywords: Judge Professional Ethics; Law Enforcement; Justice AbstrakHakim sebagaI unsur utama dalam pengadilan yang menempatkan profesinya tersebut sebagai wakil tuhan, sebab tugas hakim adalah untuk menentukan hukum dan keadilan dalam masyarakat, sehingga tanggung jawab yang diembannya sangatlah berat namun mulia.

Published: May 2023

The article presents the results of a study of the phraseological parameter of the Big Universal Dictionary of the Russian Language (V.V. Morkovkin, G.F. Bogacheva, N.M. Lutskaya, 2016) in paper format. Phraseological units (henceforth PUs) as the content of the phraseological zone marked in the structure of the dictionary entry by a rhombus (◊) served as the basis for the study. The aim is to reveal features of the headword representativeness as a key structural-semantic component of the phraseological zone and determine the research potential of the phraseological array of the Dictionary. A wide projection of phraseography is one of the characteristics of the Dictionary’s universality. The phraseological zones of the Dictionary are represented as PUs with different degrees of idiomaticity, as well as nominative and communicative units with the capacity for reproducibility in an unchanged composition. This approach is justified by the expansion of the phraseological base in modern lexicographic projects. The structural-semantic multiplicity of the headword as a component of a PU determines the universality of the phraseological zone’s content representativeness. The use of “multipath” references to a variety of dictionary entries, how many components a PU has, determines the vector projection to a wider range of types of figurative nominations. At the same time, the phraseological definition is presented only in the structure of a single dictionary entry where the headword acts as a key structural-semantic component of a PU. In phraseological zones as part of a peculiar linguistic corpus of the Russian language, a set of PUs has many aspects. Optional lexical and variant components of PUs are indicated. Words a PU usually collocates with are given. There are notes indicating the expressive-stylistic and evaluative functions of a PU; grammatical notes describing some morphological properties of the lexical components of a PU. An interpretation/meaning of a PU, or a reference to the headword in which the content of the PU is considered, is given. If there is a semantic identity, synonyms are provided. The phraseological zone may contain examples of a PU’s uses in speech and commentaries of a cognitive nature. The phraseographic objectification of the receptivity of the lexicalsemantic variant of the headword is strongly represented by compound terms and names that objectify human discursive activity. Phraseological zones in the structure of entries in which homonymic units act as headwords can become one of the potential vectors of studying phraseology. A single presentation of a phraseological definition in the dictionary shows a typical situation/situations of using PUs and is a potential linguistic material for studies in the cognitivediscursive direction.
A comparison of Czech and Slovak lexical nuclei using vocabulary parametric analysis

Published: May 2023

The article suggests a solution to the problem of the sister languages’ vocabulary comparison. The subject of research is Czech and Slovak vocabulary given in small bilingual dictionaries. The same metalanguage (Russian) of the definitions in such dictionaries makes the semantic analysis of vocabulary easy. The basic method is parametric analysis. It implies the ranking of words of a language according to four system parameters: functional, syntagmatic, paradigmatic, and epidigmatic ones. For each parameter, it is necessary to distinguish a local nucleus, which includes about 1000 words. Local parametric vocabulary nuclei make it possible to identify (1) the shortest, i.e., non-derivative and common (frequently used) vocabulary in these Slavonic languages; (2) vocabulary most commonly used in various fixed expressions and collocations; (3) vocabulary that forms the largest synonymic chains; (4) the most polysemantic vocabulary. The addition of local nuclei allows forming a big parametric nucleus. It includes words, which possess parametric weight values based on at least three parameters (out of four). For Czech, the big parametric nucleus comprises 279 words. For Slovak, it comprises 282 words. These lexical sets present the subject of the further analysis aimed at classifying the meanings of the words. At first, the authors establish that Czech and Slovak nuclei contain 61 words meaning the same in both languages. Besides, among them, there are 30 words that possess not only the same meaning but the same form as well. The big parametric nuclei do not contain false friends, i.e. words that look similar but differ in meaning. Then the authors do qualitative analysis of nuclear lexemes’ semantics. They find out that, in Czech and Slovak, basic semantic groups are formally similar, but they differ in intragroup distribution. Language data illustrate the fact that such semantic groups as “Activity”, “Abstract Notions”, “Human Being” are the dominant semantic groups in both languages. In the Slovak big parametric nucleus, a quantitative gap between them is less perceptible than in the Czech one. Besides, the semantic group “Human Being” occupies a higher position in the Slovak parametric nucleus. The dominance of the semantic group “Activity” and of the big parametric nucleus, as well as a negligible percent of words in the subgroup “Imitating Activity”, justifies the fact that, for Czech native speakers, not a person but a person-agent is of a particular importance. At the same time, the high percents of the semantic group “Nature” and of subgroup “A Person of Nature” prove that great attention to nature objects is a feature of Slovak native speakers’ worldview.

Authors: YILDIZ Zehra , TOPKOÇ Eşref
Published: May 2023

Yerli, yenilenebilir, ekolojik ve ekonomik bir yakıt olarak biyopeletler kömür ve odun gibi geleneksel yakıtlara alternatiftir. Ülkemizde tarımsal atık potansiyeli yüksek olup, tarımsal artıkların biyopelet olarak değerlendirilmesi çevre kirliliğini ve yakıt tüketiminde dışa bağımlılığı azaltacağı için ülkemizin enerji üretimine önemli etkisi olacaktır. En önemli yakıt özelliği, yakıtın ısıl değerdir. Bu çalışmada yedi farklı biyopeletin ısıl değeri hem deneysel hem de teorik olarak belirlenmiştir. Biyopeletlerin kısa analizi ve elementel analizi yapılmış, elde edilen verileri kullanılarak literatürde yer alan biyokütle için uygulanan bazı matematiksel modeller yardımıyla üst ısıl değer (ÜID) hesaplanmıştır. Hesaplamalarda kısa analiz için ve elementel analiz için yedi farklı eşitlik kullanılmıştır. Eşitlik E1, E2, E3, E4, E5, E6 ve E7 biyokütlenin kül, uçucu madde ve sabit karbon içeriklerini dikkate alarak ÜID’ni tahmin etmek için kullanılmıştır. Eşitlik E8’den E14’e kadar yedi model ise elementel analiz sonuçları dikkate alınarak ÜID’i tahmin etmek için kullanılmıştır. Ayrıca, adyabatik kalorimetre bombası kullanılarak numunelerin ÜID’leri deneysel olarak belirlenmiştir. Deneysel olarak belirlenen ÜID değerler ile en uyumlu olan kısa analiz sonuçlarından hesaplanan ÜID denkleminin E4 olduğu belirlenmiştir. Bu denklemlere göre biyopeletin ısıl değerini uçucu madde ve sabit karbon miktarı etkilemiştir. Deneysel olarak belirlenen ÜID ile en uyumlu olan elementel analiz sonuçlarından hesaplanan ÜID denklemi sadece karbon miktarına bağlı basit bir denklem olan E8 dir. Kısa analiz ve elementel analiz modelleri için sırasıyla en iyi R2 değerleri 0.8721 ve 0.7234’dir.

Published: May 2023

Orkide türleri tüm dünyada yayılışı çok geniş ve ticari değeri yüksek olan bitkiler arasında yer almaktadır. Isparta yöresi orkide türlerinin yayılışı bakımından önemli bir yere sahiptir. Bu çalışmada hem Isparta yöresinde doğal yayılış gösteren taksonların yayılış alanlarının tespiti, hem de bu taksonlara ait fenolojik ve iklimsel gözlemlerin ortaya çıkarılması amaçlanmıştır. Bu amaç kapsamında, yörede 16 tür 6 alttür olmak üzere 22 takson tespit edilmiştir. Bu taksonlara ait yapraklanma zamanı, tomurcuklanma zamanı, çiçeklenme başlama zamanı, tam çiçeklenme zamanı ve yumru olgunlaşma zamanı ile iklimsel değerlendirmelerine ilişkin bulgular verilmiştir. İklimsel değerlendirmede özellikle etkili sıcaklık toplamı isteği ve iklim tipinin belirlenmesi önemli rol oynamıştır.
Elde edilen bulgulara göre yörede, orkide türlerinin aktif faaliyetlerine mart sonunda başlayıp haziran ortasına kadar devam ettirdiği tespit edilmiştir. Yine türlerin özellikle yaz aylarında kuraklık konusunda çiçeklenme ve yumru oluşumunda hassasiyet gösterdiği belirlenmiştir. Fakat neslinin devamlılığı konusunda tolerans aralığının oldukça yüksek olduğu gözlemlenmiştir. Türlerin etkili sıcaklık isteği toplamlarının 932 ile 2010 gün derece arasında değişim gösterdiği ortaya çıkmıştır. Türlerin dağılım olarak yarı kurak iklim tipinden nemli iklim tipine göre dağılım gösterdiği belirlenmiştir. Çalışma sonucuna göre tespit edilen orkide türlerinin Isparta yöresinde geniş yayılış gösterebildiği iklimsel bakımdan çok kısıtlayıcı durumda olmadığı ortaya çıkmıştır.
Hızla artan nüfusun etkisi, yoğun tarımsal kullanım ve aşırı otlatma ve orkide yumrularının salep üretimi için usulsüz hasadının doğal orkide türleri için ciddi bir tehdit olduğu gözlemlenmiştir. Özellikle salep üretiminde kullanılan orkide türlerinin benzer ekolojik koşullarda kültüre alınarak üretiminin yapılması çalışmalarına destek ve öncelik verilmelidir. Çalışma sonuçlarının, Isparta yöresinde doğal yayılış gösteren orkide türlerinin koruma ve kültüre alınması uygulamalarına katkı sağlayacağı düşünülmektedir.

In solid waste management, the Methane (CH4) gas generation needs to be monitored and assessed for the environmental protection and prevent the CH4 gas atmospheric dispersion over the dwelling regions near dump yards. Traditional methods using gas sensors measures only gas concentration at different height and never modelled or predict the gas circulation in the atmosphere. Moreover, gas circulation near every dump yard needs to be modelled based on microclimatic conditions for human safety and environmental protection. In this paper an Unmanned Aerial Vehicle (UAV) based, dispersion of CH4 gas is monitored and assessed for the atmospheric circulation of CH4. The CH4 dispersion and atmospheric circulation are monitored through X-Band Bi-Static microwave transceiver sensor and Machine Learning (ML) Algorithm-Multi Linear Regression (MLR). CH4 concentration is assessed through the RADAR’s reflected signals from CH4 gas, whereas RADAR is fixed in the UAV. The RADAR is mounted in UAV to sense concentration of CH4 dispersion at different heights for municipal dump yard located at Thiruninravur, Tamil Nadu, India. A three-days; six-hours of field results, shows the proposed UAV-RADAR based prediction of the CH4, performs better in the range of 250-800 ppm CH4 concentration. The proposed UAV-RADAR system in tracing CH4 dispersion in lower atmosphere is validated through analytical methods and modelled based on microclimatic conditions.

The objective of this work was to evaluate the efficiency of the energy produced by photovoltaic (PV) panels with solar tracker based on fuzzy control versus a fixed position PV panel with azimuth: −23.45° and elevation: 12.39°, in the city of Pampas-Tayacaja Huancavelica Peru at 3660 meters above sea level with a south latitude: 12. 39522° and west longitude: 74.87266°. An experimental prototype of a solar tracker was implemented, with an algorithm embedded in a PIC 18F4550 microcontroller; this microcontroller sends pulses to the longitudinal positioning motor driver and latitudinal positioning motor driver. The first motor, powered with 12 Vdc and current consumption of 1.5 A, produces the movement from east to west and vice versa; the second motor, with the same electrical characteristics as the first one, generates movements from north to south and vice versa. The data acquired from the Light Dependent Resistive (LDR) sensors were sent by the microcontroller to the fuzzy logic controller implemented with the LabVIEW fuzzy system designer tool via USB communication. When evaluated, the efficiency of the PV panel with proposed fuzzy control, based tracker was higher in the clear or sunny day reaching 25.28%; and while in the cloudy day it was observed that the efficiency obtained is lower 8.97%, in both cases with respect to the fixed position PV panel. Therefore, it is concluded that the energy efficiency of the PV panel with the proposed solar tracker is always higher than that of the fixed position PV panel.

This paper presents an efficient design and real-time implementation of a controller for a large-scale grid-tied photovoltaic (PV) plant in a power system affected by disturbances. To direct the adequate amount of solar power, an Adaptive voltage and volt-ampere reactive (Volt-VAr) algorithm implemented in real-time using the Real Time Digital Simulator (RTDS) is proposed. An efficient and self-sufficient active and reactive P-Q power control scheme is proposed and implemented to transfer the generated power of the PV to the grid using a Voltage Source Converter (VSC). The proposed controller is implemented along with the PV system considered in RTDS to evaluate its effectiveness. By considering the impact of the disturbance caused by the load increase, the efficiency of the proposed power controller to transmit the generated power of the PV plant to the electrical grid system is investigated. It is observed that the hardware in the loop results verifies the advantage of the proposed method.

Neural State Estimation (NSE) is a novel application of deep learning which is concerned with interpolating the state of a distribution power grid from a limited amount of sensor data and can be represented as a non-linear graph time-series nowcasting problem. Although several authors have proposed their solutions for NSE, there is neither a comparison of approaches nor an industry-standard state of the art model yet. The main purpose of this paper is to compare these solutions to a promising new approach: recurrent graph convolutional neural networks. There are theoretical reasons to assume that this class of models is suited for solving NSE. Our experiments verify that they achieve similar performance while also presenting many unique advantages compared to the previously proposed models.

Smart gloves have attracted much attention as a typical representative of wearable human-machine interface (HMI). Traditional sensors on smart gloves are limited due to high cost, complex manufacture, which can’t meet the requirements of bio-friendliness and sustainability. This paper presents a smart glove human-machine interface based on strain sensor array of conductive hydrogels. A flexible, transparent, stretchable and sensitive hydrogel strain sensor is prepared based on a “one-pot” preparation method. The smart glove was constructed using 3D structural design combined with the sensor array. Combing with the signal processing system, the smart glove can realize the spatial motion control of the Unmanned Aerial Vehicle (UAV). The smart glove based on the hydrogel flexible sensor array showed great application prospects in the field of human-machine interaction of robot and Virtual Reality (VR).

Background: Gallstone disease is one of the most common digestive diseases leading to frequent hospital visits and its prevalence shows ethnic variability, with rates of approximately 10-15% in the United States and Europe. The present study aims to prospectively assess the outcomes of open side-to-side choledochoduodenostomy in the management of choledocholithiasis.
Methods: This hospital-based prospective observational study was conducted in the Department of Surgery, Tezpur medical College and Hospital, Tezpur, over one year period, from July 2021 to June 2022. The study includes twenty-four patients admitted to the surgery department for bile duct stone operations. After intraoperative confirmation of the criteria, these patients underwent choledochoduodenostomy. The patients were followed for 2 months postoperatively after discharge.
Results: Only a few patients had immediate postoperative complications which were managed conservatively. No patient had any evidence of retained stone, nor did they have any symptoms of cholangitis, features suggestive of the development of Sump syndrome, or any other follow-up postoperative complications.
Conclusion: Open side-to-side choledochoduodenostomy should be considered a method of choice in remote areas where endoscopic facilities are lacking and in patients where cost is a factor in deciding the choice of procedure, with reduced postoperative complications like retained stones and a shorter duration of hospital stay in expert surgical hands.

Background: We aimed to investigate the association of body mass index (BMI) with treatment response in patients with DLBCL
Material and Methods: Seventy-nine DLBCL subjects were included in this study. Data about patient age, sex, serum LDH level, presence of B symptoms, IPI score, ECOG performance score, disease stage, extranodal involvement, and BMI values at diagnosis were retrieved by retrospective patient record review. Patients were staged according to Ann Arbor classification using CT and/or PET/CT findings, and the presence of B symptoms. Body mass index was calculated by dividing weight in kilograms by height in meters squared (kg/m2). Patients were divided into groups according to their BMI as underweight (BMI≤ 18.5 kg/m2), normal weight (BMI 18.5-25 kg/m2), overweight (BMI 25-30 kg/m2), and obese (BMI≥ 30 kg/m2), as defined by the World Health Organization.
Results: Patients were divided into four groups according to their BMIs, but because there was only one patient in the underweight group, comparisons were performed between normal-weight, overweight, and obese patients. There was no statistically significant difference between these groups in terms of age, sex, serum LDH level, disease stage, presence of B symptoms, extranodal involvement, ECOG performance score, IPI score and treatment response (p= 0.070, 0.704, 0.325, 0.464, 0.254, 0.152, 0.658, 0.620, and 0.947, respectively)
Conclusion: In our study, we showed that BMI has no significant impact on treatment response in patients with DLBCL.

Background: Breast cancer is the most common malignant tumor and cause of death in women. Factors that play role in tumor metastasis are lymph node involvement, lack of tumor differentiation and hormone receptor expression, high proliferation rate, and angiogenesis. In the present study, we tried to evaluate the microvessel density (MVD) using Immunohistochemistry for the CD34 marker to investigate the amount of angiogenesis in breast cancer and its relationship with other histopathological parameters and compare it with normal tissue.
Materials and Methods: 58 paraffin-embedded samples of breast cancer were enrolled. All blocks were
sectioned and stained for estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor 2(HER 2/neu), ki67, and CD34 by immunohistochemistry (IHC) method.
Results: The mean age of patients in this study was 49.6 ± 10.6 years. Statistically, there was a significant relationship between the grade of the tumor (P = 0.01), absence of expression of estrogen receptor (P = 0.008), and progesterone receptor (P = 0.003) with MVD.
Conclusion: Due to the association between MVD, tumor grade, and absence of ER and PR expression, this valuable marker can play an important role in the prediction of prognosis in breast cancer patients and can lead to new targeted therapy in the future
Chronic Pain Experience According to the Transactional Stress and Coping Model: Associations between Different Pain Measures and Health Outcomes
Authors: HOCAOĞLU UZUNKAYA Ayla , SERTEL BERK H. Özlem
Published: May 2023

According to Lazarus and Folkman's Transactional Stress and Coping Model, chronic pain is defined as a source of stress. The model emphasizes the interaction between the person and the environment and focuses on primary (pain severity and/or frequency) and secondary appraisals (pain and/or discomfort from pain) when examining the effects of a stressor on a person's life. In this study, chronic pain was defined as a type of stress and pain stress was measured in three different ways: unidimensional pain stress (primary appraisal only), multidimensional pain stress (sum of both primary and secondary appraisals), and transactional pain stress (product of both primary and secondary appraisals). The aim of the study was to examine the relationships between the three different pain stress measures and the outcome variables of pain-related disability, negative mood and daily activity level. The study was conducted with 167 individuals with different types of chronic pain. Sociodemographic Characteristics and Pain Information Form, Visual Analog Scale, West Haven Yale Multidimensional Pain Inventory and Life Changes Questionnaire were used as data collection tools. The results of the study showed that there were significant relationships between unidimensional pain stress and disability and negative mood (r(1,167) = 0.33; 0.36, respectively); multidimensional pain stress and disability and negative mood (r(1,167) = 0.51; 0.38, respectively); transactional pain stress and disability, negative mood (r(1,167) = 0.43; 0.37, respectively) and daily activity (r(1,167) = -0.24). The results indicate the significance of new measures in the assessment of pain experience.
The Impact of Raising Awareness of the Speech Act On Speaking Ability across Gender and Proficiency Level
Authors: Ghayebi Kobra , Farrokh Parisa
Published: May 2023

The present study intended to investigate the possible effects of speech acts strategies on Iranian beginner and intermediate EFL learners’ speaking ability. The first step in conducting this research was the administration of QPT as the homogenizing tool. It was administered to 180 beginners and intermediate EFL learners. After analyzing the results, 80 males and females as starters and 80 males and females as intermediate subjects were chosen. Then, the beginner and intermediate EFL learners were randomly divided into control and experimental groups (including 40 beginner male and 40 female EFL learners in each class). Next, a pretest of speaking was administered to all the participants and the experimental groups received speech act role play as treatment. However, the researcher did not use any treatment of speech acts in control groups. After ten sessions, the posttest was administered to all participants. The findings suggested that awareness raising on speech acts resulted in a better speaking ability as compared to the simply traditional teaching of speaking for Iranian intermediate and beginner EFL learners. Additionally, intermediate EFL learners’ achievement in speaking was not in line with the beginner EFL learners’ achievement in the corresponding group. Finally, it was found that gender does not interact with awareness raising on speech acts in such a way as to produce a statistically significant effect on the beginner and intermediate EFL learners’ speaking ability.
Speaking in Worlds of Adventure: Tabletop Roleplaying Games within the EFL Classroom
Authors: Torres-Rodriguez Fabio Adrian , Martínez-Granada Liliana
Published: May 2023

Fostering spoken communication in a foreign language classroom is not an easy task. With that in mind, this paper explores a proposal to motivate students’ L2 oral communication through the practice of narrative games called tabletop roleplaying games adapted as task-based activities. It implied an action research process in which the teacher-researcher with his students reflected and intervened on the identified problematic situation: Lack of oral communication in L2. In that sense, it started with a diagnostic test that showed the current state of verbal communication in L2 in a Colombian rural public school. Next, the teacher-researcher chose to appeal to the gamification of the classroom along with the adoption of a task-based framework to activity design aiming to improve students’ motivation to take the risk of communicating in L2. The teacher-researcher applied sets of activities that progressed from traditional role-play to a tabletop roleplaying game. In accordance, video recordings, narratives, artifacts collections, and semi-structured interviews were essential to collect data. Afterward, the teacher-researcher analyzed the data with an emic approach to identify patterns in the information that uncovered the categories and subcategories of information. Consequently, the teacher-researcher concluded that the students feel better motivated using L2 if the learning environment offers opportunities for social interaction, collaborative work, and scaffolding in task-based exercises embedded in a fictional world game.
Documenting major drivers of trends in trade balance for SADC region amid the full implementation of the African Continental Free Trade Area (AFCFTA)

Published: May 2023

This study scrutinises drivers of trade performance in the SADC region amid the full implementation of the African Continental Free Trade Area (AfCFTA).  Where the short and long-run impact, through the Autoregressive Distributive Lag (ARDL) and forecasts through IRF of external debt, debt service cost, GDP per capita, Foreign Direct Investment (FDI), and Terms of Trade (TOT) on the trade balance is interrogated. In the long run, external debt, debt service costs, and GDP per capita negatively influenced the trade balance. TOT was found to be an insignificant predictor. This implies that these variables were among the significant drivers of trade balance while the impact of terms of trade is negligible in the region. FDI positively impacts regional trade balance, which informs us that it acts as a stimulus for trade in the area. Short-run results revealed that external debt and GDP per capita affected trade balance positively, while debt service costs, FDI and TOT were found to have a negative impact. IRF results showed that shocks from external debt and per capita GDP pose a positive instant impact, while shocks from FDI and TOT were proven to worsen the trade balance in the region. The region needs an FDI stimulus.
Factors inhibiting effective quality learning and teaching: a case of five schools in the EC Province of South Africa
Authors: Maqoqa Thabisa , Mvenene Jongikhaya
Published: May 2023

This article analyses factors that inhibit the quality of learning and teaching in one of the provinces of South Africa. The interpretive approach was used together with face-to-face interviews to collect data from five secondary schools. Two participants were interviewed in each school in the OR Tambo Coastal District in the Eastern Cape. Findings revealed that owing to large numbers of learners in the classroom, teachers’ workload is increased. Consequently, it is difficult for teachers to give feedback and provide learners with individual attention. Many under-resourced schools, such as rural schools, still face unacceptably high learner-teacher ratios and large classes in their schools. Teachers had problems in establishing discipline in their classrooms and dealing with the increasing noise level which made it difficult for learners to hear the teacher. It is recommended that School Governing Bodies should hire SGB-paid teachers. The Department of Basic Education should assist the schools with more classrooms. The Department of Education should also provide schools with resources such textbooks, big screens, overhead projectors and microphones in order for teachers to be effective.

Published: May 2023

South Africa is in a competitive global economy, with enterprises, industries, and service sectors demanding world-class academic, technical, and professional skills and competence. To meet these expectations, the secondary school education system must deliver high-quality learning experiences that connect all secondary school students to the real world by building a strong foundation of academic, technical, and work-related skills. This study’s aim is to explore the corporate world's involvement in the advancement of secondary school learners in moulding learners to be assets for a future workforce. In this study, we borrowed the theory of Bourdieu’s (1995) Social Theory to analyse data and to answer our question: To what degree does the corporate world involvement in secondary school benefit learners? We choose the constructivist paradigm in order to use qualitative methodologies to investigate the reality of the participants. Semi-structured interviews and photovoice were employed to collect data for this study. The population sample comprised of two secondary schools from which the researchers sought to acquire learner perspectives’ and to draw conclusions about how much the corporate sector has been able to contribute to the secondary schools to benefit learners. The study discovered that corporate world businesses get involved in various ways such as offering bursaries to learners, motivational workshops, sports kits, and so forth. This type of involvement by the corporate world usually results in improved teaching and learning, workplace experience, and chances for future employability.
Devaluing of state-owned entities: a comparative of SOE status between the 4th, 5th and 6th democratic administration
Authors: Kgarose Mathibedi
Published: May 2023

The African National Congress (ANC)-led government established a Reconstruction and Development Programme (RDP) policy in 1994, which included the introduction of State-Owned Enterprises (SOEs), with the goal of driving the economy and contributing to service delivery. SOEs are companies that are profit making, yet governments own them. As a result, SOEs are owned by the residents who elect their government and pay taxes to keep them functioning. These citizens are stakeholders in these enterprises through the government's administration. It can be argued that corruption, maladministration, and inadequate leadership accountability are the causes of the devaluation of state-owned enterprises. The 4th and 5th administration were thought to be corrupt, but the corruption appears to be immersed in the current 6th administration, with the SOEs being privatized. Corruption and similar corporate governance violations in state-owned Entities are becoming more common (SOEs). The purpose of this paper is to examine the position of State-Owned Entities and observe instances of incompetence, corruption and political interference in the operation of SOEs throughout the 4th, 5th and current 6th administration. Furthermore, this paper is a conceptual paper and it has relied heavily on secondary data and existing literatures for analysis and interpretation. The paper recommends that SOEs should be transparent to the public or stakeholders on its affairs, and the ANC to stop interfering in the administration and operation of SOEs.
Public Private Partnerships (PPPs), road tolling and highway infrastructure investment in Zimbabwe
Authors: Chilunjika Alouis
Published: May 2023

Over the last decade, developing countries have been promoting public-private partnerships (PPPs) as an alternative approach to developing infrastructure and services. This is done by utilising the efficiency and innovation of the private sector and enabling access to private-sector finance through public-private partnerships (PPP). Importantly, PPPs ensure more value for money than traditional financing options and highway and transportation infrastructure revenue sources. The study is qualitative, relied on the extensive review of written documents. In light of this, the study explores the utility and efficacy of PPPs in road tolling initiatives and highway infrastructure investment in Zimbabwe. Emphasis was placed on the PPP arrangement between the Zimbabwe National Roads Administration (ZINARA) and a South African company- Group Five, which saw road tolls being erected and operationalised to fund Zimbabwean highway infrastructure. The paper established that despite this PPP arrangement being a success, as seen by the faster completion of the trunk roads, lower project lifecycle costs, better risk allocation, faster implementation of public works and services, improved service quality and additional revenue streams a myriad of operational and administrative challenges equally dogged it. To this effect, the paper, therefore, recommends some strategies to strengthen and enhance the adoption, operationalization, and management of PPPs for road tolling and highway infrastructure investments in developing countries.
