Authors: Suharyono  , Purwantono  , Ningrum Astriawati
Published: October 2022

Muara Berau Anchorage is one of the waters in East Kalimantan that many ships visit for coal loading and unloading activities. The coal export transhipment was carried out in the Berau Estuary, Samarinda because the draft of large ships did not allow it to enter the far and shallow river channel. In the execution of loading there is often a shortage of load caused by several factors. The purpose of the study is to determine the causes and impacts of load deadfreight and efforts to reduce the occurrence of load deadfreight in the coal loading process. The methods used are descriptive qualitative. Data were collected through observation, interviews and literature studies that were tested for validity and reliability tests. The results of this study show that the cause of the load deadfreight in the MV. RB MYA is the theft of cargo along the Mahakam river, spillage of coal cargo during the loading process, and lack of supervision in the loading process at the Jetty. The impact of the deadfreight of coal cargo is the occurrence of a shortage of shiploads and the occurrence of losses for shippers. Efforts were made to reduce the occurrence of payload deadfreights in the MV. RB MYA is to hold barge escorts, increase the effectiveness of communication between the ship and floating cranes, and increase the number of Foreman Jetty.

Management of Agricultural Innovations: Implications on Food Security in Nigeria
Authors: Okopi Solomon
Published: October 2022

The article aimed to investigate the management of agricultural innovations: implications on food security in Nigeria specifically, agricultural innovation methods, benefits of adoption, impact on agricultural productivity, management of innovations and constraint faced by farmers in adoption of innovations. The article was guided by four research questions and two hypotheses tested at p ≤.05. The study adopted a descriptive research design, using a total of 103 (51= crop production) and (52 = animal rearing) farmers selected through a proportionate sampling method from 1300 farmers in Jos North, Jos Nigeria as sample for the study. The questionnaire was used to gather data. The psychometric yielded the following: CVR=1 through Lawshe’s (1975) method and r-coefficient=0.86 using Cronbach Alpha. Data gathered was analyzed using frequency counts and percentages to answer all the research questions through the application of MS Excel 2012 while, using STATAMP 14, the Pearsman Product Moment Correlation (PPMC) was used to establish the linear relationship between the variables under study. The study found hydroponic-No soil needed, aeroponics-growing plants in midair, aquaponics, water reduction intake and utilization by both plants and livestock, Harvest Quality Vision-HQV among others as various methods of agricultural innovations available to farmers. The study established that, the extent to which these innovations are beneficial to farmers is dependent on the availability of the methods. Although, farmers perceived the importance of innovation as a medium to improve food production if innovators manage their innovations through farm organization. The study found that farmers often encountered high cost of innovations, poor level of awareness and environmental factors as constraint towards adopting agricultural innovations. The study concluded that, to ensure food security in the country, there is the need for adoptable innovations. Therefore, platforms made for management of innovation should be made effective to further encourage farmers towards adoption and continuity.

Use-level lifetime distribution estimation under dependent right censored test data
Authors: Hove Herbert , Beichelt Frank
Published: October 2022

Accelerated life testing (ALT) is a practice for estimating unit reliability at normal use conditions using failure data obtained under more severe test conditions. We focus on life tests where a potential critical unit failure at X2 (unit lifetime) may be avoided by a degraded failure at some random time X1. Degraded and critical failures are linked through the degradation process,hence the situation under consideration is that of dependent competing risks. We apply the general result that if the copula C(.; .) of (X1; X2) is known, competing risks data uniquely determine the marginal distributions at each stress level. Interest here (and in life testing studies in general) is in unit lifetime. Accordingly, our target of estimation is to extrapolate a use-level lifetime distribution from which important reliability measures such as mean lifetime, warranty period among others are derived. The paper is based in part on a PhD thesis by Hove (2014).
Minimum Hellinger distance estimation for locally stationary processes
Authors: Fofana Souleymane , Diop Aliou , Hili Ouagnina
Published: October 2022

In this paper, we are interested in the estimation of locally stationary processes by the minimum Hellinger distance estimator (Beran, 1977) in spectral framework. This distance is originally applied to probability distributions. Here we apply this distance to spectral density functions belonging to a specified parametric spectral family. We generalize the minimum Hellinger distance estimation method to processes that only show a locally stationary behaviour. Asymptotic properties of the estimator are shown. The robustness of the estimator is investigated through a simulation study. An application on real data is carried out.
Multiple linear regression with constrained coefficients: Application of the lagrange multiplier
Authors: Kikawa C. R. , Kloppers P. H.
Published: October 2022

In this paper, we present two unfamiliar novel estimation techniques (UNET) for the constrained regression coefficients in the frame-work of a standard multiple linear regression model. Estimation of a linear regression problem with constraints on the regression coefficients are firstly derived by minimising a formulated goal function that minimises the total sum of the squared errors, plus the sum of the linear constraints multiplied by a Lagrangian. We also show that the solution to the system of equations can be obtained without differentiating the goal function, rather expressed in terms of the known matrices. This is achieved by employing properties of a blocked linear system. The UNET is justified by a numerical simulated system of linear equations in 3-dimensions. The UNET yields estimates that are comparable to those generated by the Schur complement principle.
Ultrasound-Assisted Extraction of Pectin from 'Saba' Banana Peel Waste: Optimization and Rheology Study
Authors: Joel Padilla Rivadeneira  , Tao Wu  , Katherine Ann Tamolang Castillo-Israel
Published: October 2022

This study utilized 'saba' banana peel waste as a source of pectin for gelling and thickening applications. Peel wastes were dried, powdered, mixed with acidified solvent, and subjected to an ultrasound-assisted extraction. Significant factors for the extraction of pectin were screened and optimized using Response Surface Methodology. The predicted optimum extraction conditions were 60% amplitude, pH 5, and 20 minutes with predicted and actual yields of 4.6% and 4.8%, respectively. The gelling ability of the ultrasound-extracted pectin (UEP) was evaluated, and results showed that the strength of the gel is directly proportional to the concentration of UEP. Moreover, the concentration of acidifier also affects gel strength – 1% glucono-delta-lactone being the most appropriate concentration of acidifier. UEP was also applied to a commercial orange juice and subjected to an in vitro digestion. Results showed that UEP increased the beverage's apparent viscosity during different digestion stages.

The application of thermoplastic composites (TPCs) in aircraft application is expanding. This paper presents a study of the effect of layering thickness of Carbon Fibre Reinforced Polyphenylene Sulfide, CF/PPS. There are 2 thickness of plies which are 6 plies and 8 plies of 1.90 mm and 2.52 mm respectively. To update, the aircraft is now ready to shift from thermoset to thermoplastics composite materials. In parallel to the technology, mechanical, thermal and physical properties of the advanced thermoplastic materials CF/PPS are to be determined. By having towards the behavior and properties, thus the incoming material CF/PPS data could be compared to the current nominal of epoxy thermoset structural for aircraft which is benefit to the aircraft industries purpose. In this study, it was found that, for mechanical properties, Tensile Strength, Flexural Modulus as well as Vickers Hardness recorded 6 plies higher value compared to 8 plies. While, Impact Strength, Interlaminar Shear Strength, (ILSS) and Compressive Strength shown that 8 plies obtained the superior reading compared to 6 plies. For physical properties, the density of 6 plies and 8 plies recorded 1.541 and 1.547 respectively. Content as a percentage of the initial mass of fibre, (%) recorded 6 plies was 58.397% while 8 plies was 58.235 %. Fibre content as a percentage of the initial volume, (%) recorded 6 plies was 50.838% while 8 plies was 50.885%. Void content as a percentage of the initial volume, (%) recorded 6 plies was 1.678% while 8 plies was 1.268%. While, for the thermal analysis, both samples of CF/PPS have good thermal stability material in aerospace applications as the weight for both plies CF/PPS are observed as the function of temperature (high heat energy applied). Glass Transition Temperature ( was 93.75°C for 6 plies while 8 plies recorded 93.94°C. Melting Temperature, recorded 283.68°C for 6 plies whereas 283.61°C for 8 plies. The morphological analysis under Scanning Electron Microscope (SEM) shows that 6 plies had a lot of fibre pull out compared to 8 plies thus agreed that impact strength was higher on 8 plies over 6 plies.
Steam Gasification of Biomass for Hydrogen Production – A Review and Outlook
Authors: Mohammad Junaid Khan  , Khaled Ali Al-attab
Published: October 2022

This article summarizes various biomass gasification methods and explains their advantages and disadvantages. First, theoretical aspects of gasification and the variety in reactor designs are overviewed. Despite the eminent effect of reactor design on gas product quality, gasification agents remain the dominant factor that determines the gas composition. Steam gasification is a thermochemical process that promotes organic carbonaceous substances into carbon monoxide and hydrogen while reducing the presence of dilutants. However, several obstacles during gasification and downstream processing have to be overcome to achieve adequate maturity. Gasification characteristics of steam were compared to the other gasification agents, including air, oxygen and CO2. The key performance parameters affecting steam gasification include raw material properties, additive and catalytic materials. While the key operating parameters include operating temperature, residence time, superficial velocity, equivalence ratio and steam-to-biomass ratio. Finally, the techno-economic evaluation and challenges facing the commercialization of steam gasification were discussed.

EFFICIENCY LIMITING FACTORS OF PETROCHEMICAL WASTEWATER TREATMENT USING HYBRID BIOLOGICAL REACTOR
Authors: Ahmed Mohd Elmuntasir , Mydlarczyk Andrzej , Al-Haddad Adel
Published: October 2022

The wastewater characteristics and some operational control parameters limit the efficiency of attached growth processes for petrochemical wastewater treatment. This study aims to determine the efficiency of a hybrid biological reactor treating actual petrochemical wastewater and to identify the efficiency determining factors. An up-flow biological reactor filled with bio-career was operated at two flow rates, two dissolved oxygen (DO) levels, and under anaerobic conditions. Due to the varying characteristics of actual petrochemical wastewater, efficiency limitations were manifested in many ways. However, the highest chemical oxygen demand and biochemical oxygen demand (BOD) removal efficiencies were 77.2% and 78.5%, respectively, and were achieved under aerobic operation at organic loading rates (OLRs) of 0.2 kg-COD/m3/d and hydraulic retention time (HRT) of 26.67 h (DO 4.0 mg/l). Anaerobically, the highest efficiency was 41.7 for both at 0.18 kg-COD/m3/d and 400 ml/min. The total organic carbon (TOC) removal stability was attributed to the presence of toxic chemicals and removal mechanisms other than biodegradation, as it tapered off at high loading. The nutrient removal efficiency was marginal, conceivably due to the high organics to nutrient ratio and toxic conditions of the wastewater promoting nutrient removal inside the biofilm.

Published: October 2022

The chrysomelid beetles Podontia affinis and Silana farinosa are members of the subfamilies Galerucinae and Cassidinae, respectively. This study, based on 16S rRNA gene-targeted metagenomics sequencing, reports the core members and differential abundance of bacterial communities in the larvae and adult beetles of P. affinis and the adult S. farinosa. Cyanobacteria/Melainabacteria group was the predominant phylum in the larvae of P. affinis, while Proteobacteria was the predominant phylum in adult P. affinis and S. farinosa. The number of Order, Family, Genus and Species OTUs in the adult stage of P. affinis was higher than that in the larval stage. The bacterial species richness of adult P. affinis was significantly higher than that of adult S. farinosa. Betaproteobacteria was the predominant class in adult P. affinis, Cyanobacteria in the larvae of P. affinis and Gammaproteobacteria in S. farinosa. The larvae and adult beetles of P. affinis and adult S. farinosa had a low number of unique and shared bacterial OTUs (> 5% relative abundance). The differences in the microbiota indicate possible differences in nutrient assimilation, host taxonomy and other stochastic processes. These findings provide new information to our understanding of the bacteria associated with specialist phytophagous chrysomelid beetles and beetles in general.

Published: October 2022

Biodiversity is the assortment of life on earth covering evolutionary, ecological, biological, and social forms. To preserve life in all its variety and richness, it is imperative to monitor the current state of biodiversity and its change over time and to understand the forces driving it. This need has resulted in numerous works being published in this field. With this, a large amount of textual data (publications) and metadata (e.g. dataset description) has been generated. To support the management and analysis of these data, two techniques from computer science are of interest, namely Named Entity Recognition (NER) and Relation Extraction (RE). While the former enables better content discovery and understanding, the latter fosters the analysis by detecting connections between entities and, thus, allows us to draw conclusions and answer relevant domain-specific questions. To automatically predict entities and their relations, machine/deep learning techniques could be used. The training and evaluation of those techniques require labelled corpora.

In this paper, we present two gold-standard corpora for Named Entity Recognition (NER) and Relation Extraction (RE) generated from biodiversity datasets metadata and abstracts that can be used as evaluation benchmarks for the development of new computer-supported tools that require machine learning or deep learning techniques. These corpora are manually labelled and verified by biodiversity experts. In addition, we explain the detailed steps of constructing these datasets. Moreover, we demonstrate the underlying ontology for the classes and relations used to annotate such corpora.
Using a Collection Heath Index to prioritise access and activities in the New Zealand Arthropod Collection
Authors: Ward Darren , Malysheva Svetlana
Published: October 2022

A Collection Health Index (CHI) is a useful approach to help scope new activities, prioritise curation and accelerate digitisation within taxonomic collections. We use a Collection Health Index (CHI), based on McGinley (1993), to profile the curation levels in the New Zealand Arthropod Collection for major insect groups. There are several highly curated and well known groups (Hemiptera, Lepidoptera, ‘Other Insects’). However, three major issues were identified: 1) curation becoming increasingly outdated in sections with large numbers of, particularly older, specimens (Coleoptera, Diptera); 2) historically poorer curation, with no resident expertise or resource (Diptera); and 3) high levels of family and genus-only material that needs further identification and a significant amount of alpha level taxonomy (parts of Coleoptera, parts of Diptera and Hymenoptera). Assessment using the CHI is simple and fast, allows future planning and is based on common issues for collection management, such as care, accessibility, organisation and data capture.
Le passage en force du droit. Les victimes de crimes correctionnalisés face à la gestion professionnelle des délais judiciaires
Authors: Rouméas Rémi
Published: October 2022

Pour maîtriser les délais des procédures criminelles, les magistrat·es sélectionnent les crimes et en poursuivent une partie sous la qualification de délit, devant le tribunal correctionnel. Depuis 2004, la place des victimes dans ce processus paraît revalorisée par l’octroi d’un droit d’appel et par la mise en œuvre de négociations locales avec les magistrat·es et avocat·es. En s’appuyant sur une enquête de quatre ans, attentive aux rapports de force, de classe et de genre, l’article relativise cet accès au droit par l’examen des effets sociaux des délais judiciaires, de leur gestion et de la rhétorique professionnelle de promotion qui s’y greffe.

Les tressautements du « devenir interface » de notre relation à l’État
Authors: Alauzen Marie
Published: October 2022

Comment s’assurer de l’identité d’une personne dans les services à distance ? L’article analyse la controverse sur la réponse française à la problématisation de l’authentification à distance dans ALICEM, une application mobile conçue par l’Agence nationale des titres sécurisés du ministère de l’Intérieur pour doter les utilisateurs des services publics d’une identité numérique sécurisée. Il décrit les raisons qui ont mené ce ministère à mettre au point cette application ainsi que les choix techniques et politiques formulés dans la technologie, avant de retracer la mise en cause et les réponses gouvernementales pour tenter d’endiguer la critique. L’étude tire de cette controverse deux enseignements sur les reconfigurations contemporaines de la relation entre un État technologique européen et les utilisateurs des services publics (nommées « devenir interface ») : la diffusion contestée d’une modalité d’action expérimentale et le souci de signaler la présence de l’État sur le marché.
Les polytechniciens et l’État
Authors: Delespierre Adrien , Dudouet François-Xavier , Joly Hervé
Published: October 2022

Longtemps l’École polytechnique a eu pour vocation première de former des ingénieurs appelés à alimenter les corps techniques de l’État. La proportion de polytechniciens démissionnaires n’a, cependant, cessé d’augmenter, au cours du xx e  siècle, pour devenir systématiquement majoritaire à compter du milieu des années 1980. L’article montre que cette transformation s’explique par un double phénomène : d’une part, l’État a de moins en moins recours aux polytechniciens pour pourvoir à ses postes d’encadrement supérieurs et, d’autre part, les polytechniciens eux-mêmes se détournent de plus en plus des corps de l’État au profit d’une internationalisation de plus en plus précoce.
La coopération au cœur des groupements d'employeurs : de l'instrumentalisation à la co-construction responsable du territoire
Authors: Angelergues Gaëlle , Condomines Bérangère
Published: October 2022

Cette étude vise à comprendre les leviers motivationnels qui conduisent les organisations à coopérer sur un territoire au sein d’un dispositif de mutualisation de ressources humaines, le groupement d’employeurs (GE). La revue de littérature permet d’apprécier une distinction graduelle entre motivations instrumentales et engagement co-responsable, avec, et pour le territoire. Menés auprès d’un GE opérant dans le secteur médico-social, nos travaux montrent les principaux mécanismes de coopération inter-organisationnelle en gestion des ressources humaines (GRH). Il apparaît que la coopération observée reste à un stade intermédiaire, dans lequel persiste une dichotomie entre les attentes des adhérents orientées vers la réponse à des contraintes externes (juridiques ou d’accès aux ressources) et le projet de GRH responsable porté par le GE. Les parties prenantes ne parviennent que partiellement à se saisir de leur responsabilité de co-employeurs.
Sport et développement territorial en Guyane. Une approche par la théorie de la base
Authors: Bastien Jérémie , Gouguet Jean-Jacques , Rougier Cyrille
Published: October 2022

Le sport peut constituer un investissement très rentable tant d’un point de vue économique que social, et cette rentabilité est d’autant plus élevée qu’on se trouve dans des territoires défavorisés où le sport est une des rares options envisageables pour générer du développement économique et de l’insertion sociale à moindre coût. C’est le cas de la Guyane. Cette région va devoir relever plusieurs défis majeurs dans les prochaines années : une démographie galopante ; des déséquilibres territoriaux considérables ; une société multiculturelle en quête d’identité ; un mal développement économique profond. Cet article montre que le sport peut contribuer à relever de tels défis à la condition que certaines contraintes soient levées. En particulier, la politique sportive de la Guyane devrait être pensée en synergie avec les autres politiques publiques (éducation, santé, transports, social…). Il est indispensable d’intégrer le projet sportif dans un projet territorial global.

Le désir de réparation, sens et limites
Authors: L’Heuillet Hélène
Published: October 2022

Réparer est un maître mot de notre époque. Tout doit désormais pouvoir être réparé, non seulement les choses mais aussi les sujets humains et leur histoire. Il faut réparer aussi bien la dégradation du corps que le trauma, l’offense que l’injustice, le paraître que l’être, le personnel et le collectif. La réparation devient un but de la justice, de la politique, de médecine et de la thérapeutique, et même des relations interpersonnelles qui engendrent leur part de heurts et de dommages. La réparation est forcément incomplète et bute contre un impossible. L’irréversibilité du temps condamne l’entreprise réparatrice. Il est impossible de revenir à l’« avant » endommagé. Mais alors pourquoi souhaitons-nous réparer ?

Published: October 2022

Cerebrospinal fluid leakage can lead to postoperative refractory headaches and meningitis. Dural injury is the main cause of postoperative cerebrospinal fluid leakage. Previously, we performed a comprehensive anatomic study on the dorsal meningovertebral ligaments in the lumbosacral regions and concluded that these ligaments are an anatomic factor leading to dural laceration. However, no clinical study has examined the relationship between dorsal meningovertebral ligaments and the incidence of intraoperative cerebrospinal fluid leakage. The goal of this study was to investigate the effect of prophylactic intraoperative pretreatment of the meningovertebral ligaments on the incidence of cerebrospinal fluid leakage during surgery. [

Previous studies have suggested a clinical advantage when placing the limb in flexion after total knee arthroplasty (TKA). We sought to measure venous flow compared with control values after TKA. Our hypothesis was that the knee flexed positioning would not adversely affect venous flow. Two cohorts were prospectively evaluated. First, volunteers were randomized to positions with the knee flexed to approximately 90° or placed in a fully extended (control) position. Venous flow velocity was measured in the femoral vein every 15 minutes for 2 hours. Subsequently, 32 patients were randomized to 1 of these 2 positions after TKA, and venous flow velocity was measured in both the operative and the contralateral limb. In the healthy volunteer cohort, mean venous flow velocity was significantly higher at all time points in the flexion group compared with the extended control group (
P
<.05). After TKA, mean flow velocity for an extended knee (control) was 28.5 cm/s. Mean flow velocity for the flexed knee, foot-dependent group was 47.2 cm/s (
P
=.036) and for the flexed knee, foot-elevated group was 30.4 cm/s (
P
=.618). Placing the limb in a flexed position after TKA is not detrimental to venous flow velocity and resulted in higher velocities relative to the extended position. Placing the limb at 90° flexion does not cause venous stasis and should not increase the risk of deep venous thrombosis. [

Capital culturel et inégalités sociales
Authors: Liénard Georges , Servais Émile
Published: October 2022

La (re)parution dans la Bibliothèque idéale des sciences sociales (Bi2S) de l’ouvrage de Georges Liénard et Émile Servais donne enfin à connaître à la communauté scientifique une enquête injustement méconnue. En effet, s’il a été publié en 1978 en Belgique aux éditions Vie ouvrière, ce livre a peu circulé en France. Il s’agit donc presque d’y donner accès pour la première fois.

Issu d’une thèse de sociologie réalisée en binôme, il rend compte de l’une des premières enquêtes sur la socialisation des enfants conduite au domicile des familles de différentes classes sociales. La nouvelle préface de Stéphane Bonnéry, après celle de Jean Remy et Jean-Claude Chamboredon, ainsi que la postface de Georges Liénard, Éric Mangez et Hugues Draelants soulignent son caractère précurseur pour la sociologie de l’éducation et des enfants.

Ainsi ce livre décrit les pratiques de socialisation différenciée selon les groupes familiaux de diverses classes sociales, les trajectoires inter et intragénérationnelles dans lesquelles elles s’inscrivent, les représentations que les enfants et leurs familles se font de leur avenir notamment le travail espéré et la position sociale à laquelle ils aspirent. À partir de ces descriptions approfondies, l’analyse sociologique montre comment les pratiques de socialisation différenciée sont à la fois une accoutumance et une intériorisation de la position sociale future.

Authors: Majumder Soumi
Published: October 2022

All over the world, the real estate sector under construction industry is one of the most hazardous sectors. The jobs consist of high risks like accidents, fatalities, and injuries. Working with height, excavation, dust, noise, heavy machinery, and modern gadgets all are playing an extensive role in the work environment of the real estate sector. Over the past few years in developing and underdeveloped countries, construction work has increased. With the development of these sectors, occupational hazards, accidents, etc. are also getting increased. To focus on Real Estate 4.0, the study emphasizes health and safety performance with the integration of artificial intelligence. As Real Estate 4.0 becomes more real, it will lead to a new series of paradigm shifts. In this study, the authors have highlighted the new industrial health and safety issues and management based on an adaptation of various aspects of artificial intelligence.

This study reviewed EC studies in China. A total of 1,982 journal articles published between 2001 and 2020 were collected from the Web of Science database. In addition, it referred to the Five-Year Plan for Economic and Social Development of the People's Republic of China and divided the research period into five-year stages. The BibExcel, UCINET, and SPSS software programs were used to conduct co-word analysis. The results indicated that (1) Stages I–IV comprised 4, 3, 4, and 4 clusters, respectively. (2) Consumer's personalized demands were considered in EC development activities ranging from the initial EC infrastructure construction to the integration of artificial-intelligence-related technology. (3) Topics regarding consumer behaviors were centered on Stages II and III, which indicated that the research on these topics was mature. (4) Stage IV explored the new research topic of integrating smart technology into the EC and indicated the characteristics of the e-market.
Assessing Rural and Urban Teenagers' Domestication of Technology
Authors: Uzuegbunam Chikezie E.
Published: October 2022

This paper focuses on a qualitative analysis of the ways in which rural and urban teens domesticate digital technologies that are available to them. The study draws from 16 focus group interviews with teenagers in the southeast and north central parts of Nigeria using a child-centered approach. Anchored on domestication and technological appropriation framework, the paper explores the circumstances whereby technology assumes the meanings and uses assigned to them by the teens. From gaming, social connections, leveraging schoolwork, information and news, family connection, to self-learning and education, the findings foreground the idea of domestication whereby the teens metaphorically tame digital technologies to suit their realities as children in specific contexts. Analysis foregrounds barriers such as digital illiteracy and other factors limiting children's digital development. Recommendations are made on how to improve children's full digital participation in the local context.
Factors Influencing Students' Continuance Intention Toward Usage of E-Learning Systems in Tanzania
Authors: Lashayo Deogratius Mathew , Mhina Julius Raphael Athuman
Published: October 2022

Few studies have investigated factors influencing students' continuance intention to use e-learning systems based on expectation-confirmation model (ECM). However, many of them have not examined all factors from ECM and that of information system success model (ISSM); rather, they picked few from both models. The crucial gap of this study is to integrate all factors from ECM and that of ISSM and propose a model for continuance intention to use e-learning systems and validates the proposed model using a sample of 424 drawn from students in four HLIs in Tanzania (i.e., IFM, CBE, DIT, and IAA). The structural equation modelling (SEM) technique was employed in analysing the collected data. The findings of this study reveal that satisfaction is the strongest predictor of students' continuance intention. Furthermore, two quality factors (information and system) are significant exogenous predictors of students' continuance intention. The resulting model showed significantly enhanced explained variance. The implications of this study and its limitations are also discussed.
Assertiveness and Self-Esteem Among Nurses in a Tertiary Hospital in Abu Dhabi, United Arab Emirates
Authors: Santiago Leika
Published: October 2022

The study describes the level of assertiveness and self-esteem among nurses and examines the relations between assertiveness and self-esteem. Quantitative descriptive correlational design was used in 100 nurse respondents working in one of the tertiary hospital in Abu Dhabi, United Arab Emirates (UAE) using demographic components, assertive behavior inventory tool (ABIT), and Rosenberg self-esteem scale (RSE). Data were analyzed. Results show that respondents are moderately assertive and have moderately high self-esteem. There is a significant relationship between assertiveness and the demographic variables while respondents' demographics did not have significant relationship with the level of self-esteem. The findings also suggested that assertiveness and self-esteem are positively and significantly correlated. Nurses are recommended to have regular assessment of their assertiveness as it affects the self-esteem and assertiveness training or other intervention that would empower and improve other nurses who are less assertive, non-assertive, and have low self-esteem.
The Impact of Macroeconomic Factors on the US Stock Exchange
Authors: Süslü Cemil
Published: October 2022

The aim of the present study was to analyze the impact of crude oil prices, the US treasury 10-year bond yield rate, and gold prices on S&P 500 stock prices using daily data of the period from 04/01/2010 to 19/11/2022. For that purpose, this study employed the ARDL method. According to the results of the ARDL method, there was no statistically significant relationship between S&P 500 stock prices and gold prices, oil prices, and US treasury 10-year bond yield rates in the long term. However, while the impact of US treasury 10-year bond yield rates and gold prices was positive in the long term, the impact of oil prices on US stock prices was negative. In the short term, the impact of oil and gold prices on stock prices was statistically significant. Consequently, study of the short-term coefficients revealed a positive relationship between US stock prices and gold and oil prices. As a result, gold and oil prices had a positive impact on US stock prices in the short term.

Herzberg's theory should be given a decent burial
Authors: Orpen Christopher
Published: October 2022

In hierdie artikel wys professor Orpen op 'n aantal emstige leemtes waaraan die tweefaktorteorie van Herzberg mank gaan. Benewens die felt dat dit gebaseer is op studies met metodologiese gebreke is elkeen van die teorie se hoofhipotesisse vervals deur navorsingstudies. In besonder voorspel die teorie nie hoe stamverbonde swartmense in die werksituasie optree nie. Die skrywer kom tot die slotsom dat dit hoop tyd is dat Suid-Afrikaanse sakelui en -bestuurders hierdie teorie afskryf.
A New Way of Looking at Work Motivation
Authors: Orpen Christopher
Published: October 2022

In hierdie artikel word 'n "teorie" van werksmotivering voorgestel wat beide komplekser en realistieser is as die twee-faktor teorie van Herzberg. Die belangrikste eienskappe van die teorie is: (a) motivering is die resultaat van die interaksie tussen 'n werknemer se opvatting aangaande sy eie bekwaamheid — die verband tussen sy bydrae en die verkryging van sekere belonings — en die waarde of belangrikheid wat aan hierdie belonings geheg word, en (b) bydrae is die resultaat van die interaksie tussen motivering, vermoë en rolpersepsie. Die praktiese implikasies van die teorie vir hoër motivering word bespreek.

In die vorm van 'n denkbeeldige balansstaat kyk dr. Rupert, eerstens, na die laste in Suid-Afrikaanse toestande deur die stelling "... that we are overbanked, overtraded, overgoverned, overdrawn, underindustrialised and undermined", te ondersoek, waarna hy, tweedens, na die positiewe dinge kyk en Suid-Afrika se bates: voedsel, energiebronne, geweldige reserwes aan grondstowwe, beskikbare mannekrag en die vrye ondernemingstelsel, agtereenvolgens bespreek.
The Background of the 1977 Budget
Authors: Van S. Smit Robert
Published: October 2022

In hierdie voordrag ontleed dr. Smit die Suid-Afrikaanse ekonomie tot en met die huidige tyd en die gevolglike doelwitte van die 1977-begroting. Die diagnose fokus hoofsaaklik op sekere probleemareas: die betalings-balans en reserweposisie, die groei en produksie en indiensneming, inflasie en die omvang van subsidies ten koste van die belastingbetaler. Die skrywer waarsku egter daarteen dat ons nie die sterk punte moet miskyk nie, iets wat 'n mens al te maklik doen in die huidige pessimistiese klimaat.
