Effects of School Heads’ Guidance and Counselling Strategy for Students’ Character Formation in Public Secondary Schools in Arusha Region, Tanzania
Authors: Sebastian Williams Rajarethinam , N. Siamoo Peter , Lyamtane Eugene
Published: November 2024

The study focused on the effects of school heads' administrative strategies on students' character formation in public secondary schools in the Arusha region, Tanzania. The study was guided by one research question and one hypothesis, and it employed a convergent design using a mixed methods approach to examine the problem. The research employed probability and non-probability sampling methods to select 177 teachers, 249 parents, 360 students, and 18 school heads from 18 chosen secondary schools. Data were gathered using questionnaires administered to teachers, parents, and students and interviews conducted with the heads of schools. The instruments were validated, and the reliability of the questionnaire was assessed using Cronbach's Alpha coefficient for Likert scale items. For qualitative data, reliability was confirmed through peer review and triangulation. Quantitative data were analysed using descriptive statistics, including mean scores, frequencies, and percentages, and then presented in tables. A hypothesis was tested using simple linear regression at a significance level 0.05. Qualitative data were analysed using contextual analysis and transcription. This study found that schools had a well-defined guidance and counselling programme in place but needed more professional counsellors, and it needed further improvement through external sources. Furthermore, the findings revealed no significant correlation between the guidance and counselling strategies of public secondary school heads and the levels of character development among students in the Arusha Region. This study concluded that while school heads’ guidance and counselling strategy positively affected students' character formation and goal-setting, this was achieved in collaboration with parents and professionals despite challenges and differing viewpoints among stakeholders. The recommendation study encourages teachers to participate actively in counselling seminars and strengthen collaboration with NGOs.

Observations of the Galactic bulge revealed an excess of short-timescale gravitational microlensing events that are generally attributed to a large population of free-floating or wide-orbit exoplanets. However, in recent years, some authors suggested that planetary-mass primordial black holes (PBHs) comprising a substantial fraction (1%–10%) of the dark matter in the milky Way may be responsible for these events. If that was the case, a large number of short-timescale microlensing events should also be seen toward the Magellanic Clouds. Here, we report the results of a high-cadence survey of the Magellanic Clouds carried out from 2022 October through 2024 May as part of the Optical Gravitational Lensing Experiment. We observed almost 35 million source stars located in the central regions of the Large and Small Magellanic Clouds and found only one long-timescale microlensing event candidate. No short-timescale events were detected despite high sensitivity to such events. That allows us to infer the strongest available limits on the frequency of planetary-mass PBHs in dark matter. We find that PBHs and other compact objects with masses from 1.4 × 10−8
M
⊙ (half of the Moon mass) to 0.013 M
⊙ (planet/brown dwarf boundary) may comprise at most 1% of dark matter. That rules out the PBH origin hypothesis for the short-timescale events detected toward the Galactic bulge and indicates they are caused by the population of free-floating or wide-orbit planets.
On some new and poorly-known Chrysillini from arid western South Africa (Araneae, Salticidae)
Authors: Haddad Charles Richard , Wesołowska Wanda
Published: November 2024

Following a rapid biodiversity assessment of spiders in the arid western interior of South Africa, we report on the occurrence of some poorly known and new species of chrysilline jumping spiders. Helafricanus patellaris (Simon, 1901), Heliocapensis capensis (Wesołowska, 1986), H. mirabilis (Wesołowska, 1986) and Menemerus lesserti Lawrence, 1927 are recorded from the Northern Cape Province for the first time, and Heliocapensis maluti (Wesołowska & Haddad, 2014) (Lesotho) and Heliophanus deformis Wesołowska, 1986 (Angola) are recorded from South Africa for the first time, both also from the Northern Cape. The hitherto unknown females of Heliocapensis mirabilis (Wesołowska, 1986) and Icius pulchellus Haddad & Wesołowska, 2011 and the male of M. lesserti are described for the first time. Three new species are described: Icius jacksonisp. nov. (♂), Menemerus foordisp. nov. (♂) and Natta triguttatasp. nov. (♂♀). One new combination, Afraflacilla matabelensis (Wesołowska, 2011), comb. nov. (ex Pseudicius Simon, 1885), is proposed. We present the first comprehensive molecular analysis of South Africa Chrysillini jumping spiders, based on the cytochrome oxidase I (COI) gene, which supports the monophyly of all but two genera (Helafricanus Wesołowska, 1986 and Heliophanus C.L. Koch, 1833), which we briefly discuss.

Published: November 2024

The African Cladocera fauna is recognized by high endemism. Several studies have helped to understand the diversity and geographic distribution of some groups of Chydoridae on the continent. However, the literature indicates the presence of species whose natural distribution is presumed to be in other continents, suggesting that the diversity and endemism in Africa are still underestimated. Despite the absence of more comprehensive knowledge about morphology of Kurzia longirostris to terra typica (Oriental region), our findings reveled slightly morphological differences between Congo River populations when compared with literature data. Looking at the high morphological variability along the range of geographic distribution, it is increasingly clear that K. longirostris might be indicated as a species complex. Thus, the idea of continental endemism should be tested in a future revision of the group.
A new species of Khorata Huber, 2005 (Araneae, Pholcidae) from Jiangxi Qiyunshan National Nature Reserve, southern China
Authors: Zhou Guchun , Lu Jian , Deng Yutong
Published: November 2024

Khorata Huber, 2005 contains 52 species distributed in Cambodia, China, Laos, Thailand and Vietnam, out of which about 34 species have been recorded from China. It can be distinguished from all other genera of Pholcidae by the male chelicerae with lateral ledges and the cheliceral apophyses with cuticular ridges or scales. The femur of the male palp features a retrolateral apophysis. The male palp is small, characterised by a prolaterally attached genital bulb that lacks projections, except for the embolus. The carapace exhibits a shallow median groove and the female abdomen shows no posterior pockets.

A spider survey conducted in June 2024 from the Jiangxi Qiyunshan National Nature Reserve, Jiangxi, China recorded the genus Khorata for the first time. Based on morphological comparison, one new species was identified and is described here. A detailed description, diagnosis, photographs and distribution map of the new species are provided.

Analysis of the excitation function of deuteron induced nuclear reaction on Neon-20 using COMPLET code
Authors: Degu Belete Guadie , Asres Yihunie Hibstie , Zegeye Senamaw Mequanent , Alemu Yesigat Enawugaw
Published: November 2024

In this study deuteron induced nuclear reaction on 20Ne target was studied to get nuclear information about 18F and 21Na radioisotopes which are widely used in medical and nuclear reactor technologies respectively. This nuclear reaction is important to get nuclear data since the produced radioisotope is widely used in nuclear medicine due to its appropriate short half-life and positron emitter. The main objective of the study was to analyse and interpret the behaviour of the resulting reaction cross section. It also aimed to compare the computed theoretical result with the experimental data retrieved from IAEA EXFOR for its validity. From such nuclear reaction, the reaction cross sections of 20Ne(d, α)18F, 20Ne(d, x)18F, and 20Ne(d, n)21Na reaction channels were computed using a nuclear computational code called COMPLET. The computed reaction cross sections for each channel were found in good agreement with the experimental data within the specified energy range and show a strong correlation as assessed by Pearson’s correlation coefficient. The analysis of the result shows that compound nucleus reaction is found the dominant reaction mechanism at the lower energies of the projectile.
Generalized third-kind Chebyshev tau approach for treating the time fractional cable problem
Authors: Abd-Elhameed Waleed Mohamed , Alqubori Omar Mazen , Al-Harbi Abdulrahman Khalid , Alharbi Mohammed H. , Atta Ahmed Gamal
Published: November 2024

This work introduces a computational method for solving the time-fractional cable equation (TFCE). We utilize the tau method for the numerical treatment of the TFCE, using generalized Chebyshev polynomials of the third kind (GCPs3) as basis functions. The integer and fractional derivatives of the GCPs3 are the essential formulas that serve to transform the TFCE with its underlying conditions into a matrix system. This system can be solved using a suitable algorithm to obtain the desired approximate solutions. The error bound resulting from the approximation by the proposed method is given. The numerical algorithm has been validated against existing methods by presenting numerical examples.
Spatial behavior for the quasi-static heat conduction within the second gradient of type Ⅲ
Authors: Shi Jincheng , Li Shuman , Xiao Cuntao , Liu Yan
Published: November 2024

This article focused on investigating the spatial behavior of the quasi-static biharmonic conduction equation within the framework of type Ⅲ of the second gradient in a two-dimensional cylindrical domain. The results of growth or decay estimates were established by using a second-order differential inequality. When the distance tends to infinity, the energy either grows exponentially or decays exponentially. The results showed that the Saint-Venant principle was also valid for the quasi-static biharmonic conduction equation.
Analysis of drug-resistant tuberculosis in a two-patch environment using Caputo fractional-order modeling
Authors: Wang Hongyan , Jiang Shaoping , Hu Yudie , Lonapalawong Supaporn
Published: November 2024

In this study, a fractional-order mathematical model of the transmission dynamics of drug-resistant tuberculosis within a two-patch system incorporating population migration was proposed and analyzed using the Caputo operator. The positivity, boundedness, existence, and uniqueness of the solutions as well as the Ulam-Hyers stability of the model were guaranteed. Additionally, the basic reproduction numbers were derived and analyzed for sensitivity to identify the key parameters that affected the spread of drug-resistant tuberculosis. Moreover, the cure rates were used as control variables to formulate an optimal control problem, which examined the efficacy of the control measures and the influence of fractional order on the control values. The numerical results showed that controlling the cure rate can significantly reduce the number of drug-resistant tuberculosis infections, thus verifying the effectiveness of the proposed control strategy. As the fractional order decreased, the duration during which the maximum control intensity was applied in both patches increased.
Optimal homotopy analysis method for (2+1) time-fractional nonlinear biological population model using $ {{J}} $-transform
Authors: Ali Khalid K. , Mohamed Mohamed S. , Maneea M.
Published: November 2024

This paper presents a comprehensive study of the (2+1) time-fractional nonlinear generalized biological population model (TFNBPM) using the $ J $-transform combined with the optimal homotopy analysis method, a robust semi-analytical technique. The primary focus is to derive analytical solutions for the model and provide a thorough investigation of the convergence properties of these solutions. The proposed method allows for flexibility and accuracy in handling nonlinear fractional differential equations (NFDEs), demonstrating its efficacy through a series of detailed analyses. To validate the results, we present a set of 2D and 3D graphical representations of the solutions, illustrating the dynamic behavior of the biological population over time and space. These visualizations provide insightful perspectives on the population dynamics governed by the model. Additionally, a comparative study is conducted, where our results are juxtaposed with those obtained using other established techniques from the literature. The comparisons underscore the advantages of optimal homotopy analysis $ J $-transform method (optimal HA$ J $-TM), highlighting its consistency and superior convergence in solving complex fractional models.
A mathematical model for the study of latent tuberculosis under 3HP and 1HP regimens
Authors: Moya Erick M. D. , Rodrigues Diego Samuel
Published: November 2024

In this paper, we proposed a mathematical model for the study of tuberculosis treatment with latent treatment, taking into account the 3HP and 1HP. The model is constructed using a fractional order derivative in the Caputo sense to take advantage of the memory effect. The aim is to compare the impact on tuberculosis, whether we keep the therapies that are applied to latent tuberculosis, use of once-weekly isoniazid-rifapentine for 12 weeks (3HP), or use of isoniazid and rifapentine once a day for 28 days (1HP). We presented the basic properties of the model and found the basic reproduction number. We performed computational simulations with different fractional orders to study the behavior of the model. We studied the variation of parameters associated with new latent therapies and different treatments for active tuberculosis in the basic reproduction number. We found that the implementations have a positive impact, as the basic reproduction number remains less than unity. We showed that both implementations enable positive results because they reduce active tuberculosis in the population. The 1HP results were better and showed that the duration of treatment positively influences adherence to therapy.
Matching and Agglomeration: Theory and Evidence From Japanese Firm‐to‐Firm Trade
Authors: Miyauchi Yuhei
Published: November 2024

This paper shows that matching frictions and a thick market externality in firm‐to‐firm trade shape the agglomeration of economic activity. Using panel data of firm‐to‐firm trade in Japan, I demonstrate that firms gradually match with alternative suppliers following an unanticipated supplier bankruptcy, and that the rate of rematching increases in the geographic density of alternative suppliers. Motivated by these empirical findings, I develop a general equilibrium model of firm‐to‐firm matching in input trade across space. The model reveals that the thick market externality gives rise to an agglomeration externality affecting regional production and welfare. Using the calibrated model to the reduced‐form patterns of firm‐to‐firm matching, I estimate that the elasticity of a region's real wage with respect to population density due to the thick market externality is approximately 0.02. This finding highlights the substantial impact of the thick market externality on the overall agglomeration benefit.
Caution and Reference Effects
Authors: Cerreia-Vioglio Simone , Dillenberger David , Ortoleva Pietro
Published: November 2024

We introduce Cautious Utility, a new model based on the idea that individuals are unsure of trade‐offs between goods and apply caution. The model yields an endowment effect, even when gains and losses are treated symmetrically. Moreover, it implies either loss aversion or loss neutrality for risk, but in a way unrelated to the endowment effect, and it captures the certainty effect, providing a novel unified explanation of all three phenomena. Cautious Utility can help organize empirical evidence, including some that directly contradicts leading alternatives.
Ambiguous Contracts
Authors: Dütting Paul , Feldman Michal , Peretz Daniel , Samuelson Larry
Published: November 2024

We explore the deliberate infusion of ambiguity into the design of contracts. We show that when the agent is ambiguity‐averse and hence chooses an action that maximizes their minimum utility, the principal can strictly gain from using an ambiguous contract, and this gain can be arbitrarily high. We characterize the structure of optimal ambiguous contracts, showing that ambiguity drives optimal contracts toward simplicity. We also provide a characterization of ambiguity‐proof classes of contracts, where the principal cannot gain by infusing ambiguity. Finally, we show that when the agent can engage in mixed actions, the advantages of ambiguous contracts disappear.
Au-delà de la focalisation : la pseudo-clivée comme stratégie de recherche d’adhésion
Authors: Berthe Florine , Gaudy-Campbell Isabelle
Published: November 2024

La pseudo-clivée est une structure syntaxique présentant un agencement en deux temps articulés autour de la copule be, le premier correspondant à une proposition en what et le second temps étant celui focalisé. En anglais oral, ce second temps correspond fréquemment à un segment complexe pouvant être de l’ordre d’un paragraphe (Auer, 2009 ; Gaudy-Campbell et al., 2016). La résolution du pseudo-clivage n’est alors pas immédiate. Si les pseudo-clivées sont traditionnellement analysées pour leur fonction focalisante, cet article cherche à rendre compte de leur usage stratégique en discours, où elles sont alors traitées comme un outil argumentatif visant à présenter une situation commune, voire à la construire, et à préparer une adhésion du co-énonciateur au segment rendu saillant.À partir d’un corpus d’anglais oral britannique (Berthe, 2021), cet article met au jour différentes stratégies mises en place par l’énonciateur à cette fin. La pseudo-clivée peut tout d’abord être utilisée pour introduire un passage complexe dans lequel des connaissances présentées comme étant partagées sont réactivées en amont de la résolution du pseudo-clivage. Ce passage complexe peut également permettre à l’énonciateur de fournir un cadre situationnel qui inclura le co-énonciateur dans cet univers commun. Enfin, le passage complexe introduit par la pseudo-clivée peut également présenter une forme d’altérité énonciative qui permettra de partager avec le co-énonciateur des représentations discursives communes.
Question Sequences and Salience in TED Talks
Authors: Cardo Michele , Celle Agnès
Published: November 2024

La saillance est souvent convoquée en linguistique en référence à l’importance d’une partie du discours (mot, expression, fonction grammaticale) (Col, 2011). En tant que telles, les séquences de questions peuvent être considérées comme un procédé discursif visant à rendre saillant le propos par la répétition. De plus, la nature répétitive d’une séquence de questions tend à affecter l’attention du public, ce qui peut conduire à la perception de l’emphase sur le propos de la séquence. En tant que procédé d’emphase sur un certain sujet, la saillance peut sembler difficile à quantifier. Toutefois, on peut proposer des outils de mesure qui ont déjà été discutés dans la littérature linguistique. À la suite de Falk (2014 : 4), on considère que “la principale caractéristique de la saillance est son rôle dans l’encodage de la prévisibilité ou l’éventualité de la mention (antérieure ou à venir) d’une partie de discours continue ou discontinue dans la séquentialité temporelle du modèle mental”. Cette position nous amène à examiner comment les séquences de questions sont utilisées par les présentateurs de TED talks. On montre que ces séquences visent à créer un cadre discursif de nature à faire comprendre au public l’importance d’un certain sujet. En outre, les séquences de questions des TED talks peuvent attirer l’attention du public soit vers l’amont, soit vers l’aval du discours.À la manière de Celle et Liégeois (2021), le présent article analyse un corpus transcrit de TED talks en anglais. Le corpus comprend l’ensemble des séquences de questions tirées de 18 talks transcrits. Les talks sont présentés par des locuteurs de différents horizons. Nous proposons une hiérarchie des séquences de questions, et déterminons comment les séquences de questions peuvent rendre le propos saillant et créer un sens d’anticipation pour le public. Notre proposition s’inscrit directement dans la lignée de travaux antérieurs sur la saillance en linguistique, tout en précisant l’apport des questions dans la présentation d’un jeu discursif.

Analysis of Euphemism Teaching in Teaching Chinese as a Foreign Language Under the Environment of Modern Educational Technology
Authors: Wang Yongliang
Published: November 2024

This article first discusses the application of modern educational technology in teaching Chinese as a foreign language (TCFL) and analyzes its impact on TCFL. Secondly, the psychological issues of international students learning euphemisms were examined. In addition, the learning effectiveness of intelligent human-computer interaction (HCI) euphemism teaching was also discussed. At the same time, the classification accuracy of the intelligent human-machine interaction euphemism teaching system's automatic discrimination was analyzed. The results indicate that most international students feel nervous and anxious when learning euphemisms. The TCFL intelligent HCI euphemism teaching system has improved the effectiveness of euphemism learning for international students, improved the accuracy of euphemism recognition, and facilitated their euphemism learning. This article provides important references for the research direction of TCFL international student psychology and artificial intelligence in assisting teaching Chinese as a foreign language.
The Expanded and Intensive Trade in Turkey's Automotive Sector
Authors: Temiz Dilek , Kutlu Rasim , Gökmen Aytaç
Published: November 2024

Extensive trade is the export of existing foreign trade countries in a country at a higher amount or price. Intensive trade is the average of new products exported or new exports made by existing foreign trade in a country. The study found that the quantity component was 77.97% and the price component was 17.82%. Turkey's common trade share in automotive sub-industry production is 4.21%. According to these findings, it is seen that the strength of Turkey's automotive main and sub-industry exports stems from intense trade. It also appears that intense trading means a large number of pieces of the price device are being explained.
Mega-costalism, socialising, and prosperity gospel in the South African context
Authors: Kgatle Mookgo S.
Published: November 2024

There is a rising phenomenon of mega Pentecostal churches in South Africa and elsewhere on the continent of Africa, which is conceptualised here as mega-costalism. The phenomenon refers to churches with mega-church buildings that can attract large crowds in church attendance. Previous studies have focused on the prosperity gospel and the socialising aspect of membership in mega Pentecostal churches. This literature review on the mega Pentecostal churches has some economic, sociological, and theological implications. Economically, the larger the church is the more income in tithes and offerings can be received. Sociologically, the church creates an opportunity for the sharing of common interests, socialising, and interaction of the church members with one another. However, theologically (particularly in the discipline of missiology), there is a need to research how megachurches can orientate their members on discipleship-making, with some implications for fulfilling the mission of God. To fill this gap, this article uses missional ecclesial imagination as a theoretical framework, to argue that the primary purpose of the church goes beyond the aspect of socialising among members and a prosperity gospel, towards the fulfilment of the mission of God. Therefore, the missional ecclesial imagination is relevant for the orientation of megachurches towards the mission of God. Data were collected by reviewing the literature on the mega Pentecostal churches in Africa, the missional ecclesial imagination, the prosperity gospel, and the socialising among church members.Contribution: This article makes a unique contribution to the research on mega Pentecostal churches by proposing a missional ecclesial imagination, which is relevant for the church’s orientation towards discipleship-making, with some implications on the mission of God.
Performance evaluation of non-invasive cardiac output monitoring device (HemoVista) based on multi-channel thoracic impedance plethysmography technology
Authors: Park Jaehee , Choi Byung-Moon
Published: November 2024

Background: A non-invasive method of measuring cardiac output (CO) can be beneficial in the care of critically ill patients. HemoVista (BiLab Co., Ltd.) is a medical device that measures CO non-invasively using multi-channel impedance plethysmography technology. The purpose of this study was to exploratively evaluate the performance of HemoVista in critically ill patients undergoing CO monitoring with the FloTrac (Edwards Lifesciences).Methods: After non-invasively installing the HemoVista sensor in critically ill patients whose CO was monitored with the FloTrac, CO values measured by both devices were collected for 30 minutes. Cardiac output measured by both devices was selected every 10 seconds, creating approximately 360 data pairs per patient. Linear correlation analysis with Pearson correlation coefficients, Bland-Altman analysis, and four-quadrant plot analysis were performed to evaluate the performance of HemoVista.Results: A total of 7,138 pairs of CO data from the 20 patients were included in the analysis. A significant correlation was observed between the two methods of measuring CO (Pearson's r=0.489, P<0.001). The mean bias was 1.03 L/min, the 95% CI for the limit of agreement was –1.83 L/min to 3.93 L/min and the percentage error was 55.8%. The concordance rate of time-dependent CO between the two devices was 14.6%.Conclusions: It was observed that the current version of HemoVista has unsuitable performance for use in intensive care units. To be used for critically ill patients, the algorithm must be improved and reevaluated with an enhanced version.
The relationship between glenoid osteometry and recurrent anterior glenohumeral instability
Authors: Thiong'o Wachira J. , Sitati Fred C.
Published: November 2024

The most common joint to dislocate is the glenohumeral joint, resulting in chronic pain and limited function. The role of the  capsuloligamentous structures and muscle balance in contributing to shoulder stability has been well documented in the literature but  the case is not the same for the bony anatomy of the glenoid. There is limited data on the contribution of glenoid osteometry in increasing the risk of anterior shoulder dislocation. This study sought to find out the association between anterior glenohumeral  instability and glenoid anteversion/inclination. A retrospective, case-control study was carried out. The study was carried out at the  Departments of Radiology and Imaging at two university hospitals. Shoulder Magnetic Resonance Imaging (MRI) scans for 45 patients  aged between 18 to 45 years with recurrent anterior shoulder instability were used in the study and compared with a control consisting  of shoulder MRIs of 45 patients with other shoulder pathologies but having no incidences of dislocation. A structured data collection tool  was used to collect the data. Data was analyzed using Statistical Package for the Social Sciences (SPSS) version 26. The mean age for all  the participants was 32.0 (SD 9.0) years. The mean age for the cases was 29.0 (SD 8.7) years, while for the controls was 34.6 (SD 8.5) years.  The glenoid was anteverted in 40% and 35.6% of cases and controls respectively (p = 1.00) and retroverted in 60% and 64.4% of  cases and controls respectively (p =0.666). Most of the glenoids were superiorly inclined (91.1% and 93.3% for cases and controls  respectively. The differences in the glenoid version and inclination between the cases and controls were not statistically significant (p =  0.288 and p = 0.489 for the glenoid version and inclination respectively. Glenoid version and inclination are not significantly increased in  patients with anterior shoulder instability compared to unmatched controls.
organisation : de la crise à la résilience et au changement
Authors: Hernandez Émile-Michel , Gahlam Nadia
Published: November 2024

Aujourd’hui, on peut dire sans exagération que les entreprises vivent dans un contexte de danger permanent et que les périodes calmes sont plus l’exception que la règle. Un acronyme, apparu à la fin des années 1980 dans les analyses de l’école de guerre américaine, et dû au théoricien David Galula, caractérise l’époque actuelle, celui de VUCA, formé des initiales des quatre mots anglais Volatility, Uncertainty, Complexity, Ambiguity. Il a, depuis, été largement adopté par le monde des organisations pour décrire l’environnement dans lequel elles évoluent.Face à la fréquence des crises, la question qui se pose est de savoir si, dans un contexte « VUCA », les organisations peuvent passer d’une attitude passive, voire réactive, à une attitude véritablement proactive. La résilience devenant alors une dimension centrale du processus gestionnaire à travers le développement, au sein des organisations, d’une véritable ingénierie de la résilience.C’est la capacité de résilience de l’organisation qui lui permet de transformer les difficultés rencontrées en opportunités de changement, en facteurs d’évolution à même d’assurer son renouvellement et, par conséquent, sa pérennité.

Then reliability of the   questionnaire   using  Cronbach  Alpha  reliability   estimate    ranges   from  .84   for   internal locus of control    to     .86  for  external locus of control while the reliability estimate of the high ability   Students’ Mathematics achievement test was established through Kuder Richardson formula K-R20 which gives .85.  This therefore     imply   that     both     internal and  external   locus of   control    influence     Mathematics   achievement of high ability   students. The hypotheses were tested using   Pearson Product Moment. Correlation Coefficient.  All   hypotheses   were   tested at -05 level of significance. The findings of the study revealed that   internal   locus of control  and external  locus of control  individually   relate   to academic   achievement  in   Mathematics   of high   ability   students in Calabar   Metropolis      of  Cross River State, Nigeria.  It was  therefore concluded that Mathematics  achievement  of  high ability  students     depends   on    their internal   and external   locus  control. Based on finding and conclusion of the study, it was  recommended amongst   others that  educational institutions should integrate  programs that promote an internal locus of control among high ability students. This  should  include training in goal-setting, self-reflection, and self-regulation strategies to help students recognize the impact of their efforts on their academic outcomes.

Introduction : l’utilisation de la médecine traditionnelle dans le traitement de l’hypertension artérielle est courante au Togo. L’objectif  de cette étude est d’évaluer la toxicité sub-chronique de trois plantes médicinales utilisées dans le traitement de l’hypertension artérielle  à Lomé.
Matériels et Méthodes : il s’est agi d’une étude expérimentale réalisée sur une période de 4 mois du 1 er août au 30 novembre 2022.  Elle a consisté à évaluer la toxicité sur 28 jours de trois extraits de plantes médicinales utilisées pour traiter l’hypertension artérielle dans  le district sanitaire du Grand Lomé, (Uvaria chamae, Acanthospermum hispidum, Senna rotundifolia) à des doses de 250 mgkg-1 , 500  mgkg-1 et de l’eau distillée aux rats témoins. Le comportement et les poids des rats ainsi que des paramètres hématologiques et  biochimiques ont été analysés.
Résultats : L’administration des extraits pendant les vingt-huit jours n’a provoqué aucun signe clinique de toxicité et aucun décès. Les extraits éthanoliques de Acanthospermum hispidum à 250mg/kg ont induit une baisse pondérale  significative des rats à partir du 13e jour jusqu’au 29e jour. Une baisse significative du volume globulaire moyen a été observée avec les extraits éthanoliques Senna rotundifolia à 500 mgkg1 et Acanthospermum hispidum à 250 mgkg-1 et 500 mgkg-1 . Une augmentation  des Aspartates aminotransférases a été retrouvée avec l’extrait éthanolique de Uvaria chamae. L’élévation de la créatininémie a été  observée avec l’extrait éthanolique de Acanthospermum hispidum à 500 mgkg-1.
Conclusion : L’étude de la toxicité de ces plantes chez  les rats Wistar révèle un effet mineur qui nécessite d’être confirmé chez les utilisateurs humains

Objectif : Evaluer la qualité de la prise en charge du nouveau-né de faible poids de naissance (FPN) dans un contexte de soins optimisés.  
Méthodes : Il s’est agi d’une étude évaluative menée dans trois zones sanitaires du département du Zou au Bénin, la zone sanitaire de Zogbodomey-Bohicon-Zakpota (ZoBoZa) dans laquelle le modèle de soins optimisés était implémenté et les deux autres  zones sanitaires que sont Abomey-Djidja-Agbangnizoun (DAA) et Cove-Ouinhi-Zagnanando (CoZO) qui ne bénéficient pas du modèle. Le  modèle d’évaluation de la qualité de soins de DONABEDIAN était utilisé avec la prise en compte des trois composantes que sont les  intrants, le processus et les résultats, puis celle de PIRKLE et al., pour apprécier la qualité des soins. Le volet analytique avait permis de  comparer la qualité de la prise en charge entre les différentes zones sanitaires en utilisant les tests de Chi-carré non corrigé de Karl  Pearson avec un seuil de signification statistique de 5%.
Résultats : Le niveau de qualité globale de prise en charge des nouveau-nés de  FPN était jugé bon dans la zone sanitaire ZoBoZa. En effet, on observait une bonne disponibilité en intrants, une bonne qualité du  processus de prise en charge des FPN et de bons résultats en ce qui concerne leur état de santé dans la zone sanitaire ZoBoZa  contrairement aux deux autres zones.
Conclusion : Le modèle de soins optimisés permet d’améliorer la qualité de prise en charge et  contribue à la survie du nouveau de FPN.

Cette étude vise à vérifier l’existence d’une relation entre la justice organisationnelle et la satisfaction professionnelle des employés dans  le secteur de l'architecture et du génie civil, en mettant l'accent sur les entreprises BTP (Bâtiments et Travaux Publics). À partir d'une  enquête menée auprès de 316 employés travaillant dans diverses entreprises de BTP au Togo, nous avons analysé les perceptions de  justice distributive, procédurale, et interactionnelle et leur impact sur la satisfaction au travail. Les résultats indiquent que ces trois types  de justice sont des prédicteurs significatifs de la satisfaction professionnelle. Ces résultats soulignent l'importance d'établir des procédures équitables et transparentes ainsi que de maintenir des relations interpersonnelles respectueuses pour améliorer la  satisfaction des employés. Les implications pratiques pour les gestionnaires du secteur BTP sont discutées, notamment en termes de politiques de ressources humaines et de formation à la justice organisationnelle.

Au Burkina Faso les micro-bassins sont des zones à fortes potentialités agricoles. La présente étude vise à déterminer les différents types de sols et d’évaluer leurs potentialités agronomiques dans les microbassins des communes de Koumbia et de Satiri, respectivement dans les provinces du Tuy et du Houet au Burkina Faso. La description des sols a été faite suivant les normes FAO en vigueur et leurs niveaux de fertilité, selon la grille d’appréciation du Bureau National des Sols. Les résultats ont montré que dans la commune de Satiri, les micro-bassins sont dominés par des sols ferrugineux tropicaux lessivés à concrétions (28,99%), lessivés indurés peu profonds (26,16%) et les sols ferrugineux tropicaux lessivés indurés superficiels (22,80%). Dans la commune de Koumbia, huit (08) types de sols ont été identifiés dont les sols ferrugineux tropicaux lessivés indurés superficiels (28,60%), ferrugineux tropicaux lessivés indurés peu profonds (23,95%) et les sols hydromorphes peu humifères à pseudogley de surface (24,84%). La quasi-totalité des sols identifiés à Satiri ont montré un niveau de fertilité « moyen » ; tandis qu’à Koumbia, 65,49% des sols ont un niveau de fertilité « moyen » et 30,28%, un niveau de fertilité « très bas ». Ces résultats augurent des perspectives de mise en place des stratégies de gestion durable de la fertilité des sols à l’échelle des micro-bassins versants.
 
In Burkina Faso, micro-watersheds are areas with high agricultural potential. The aim of this study is to determine the different types of soil and assess their agronomic suitability in the micro-basins of the communes of Koumbia and Satiri, respectively in the Tuy and Houet provinces of Burkina Faso. Soils were described according to current FAO standards, and their fertility levels according to the assessment scale of the National Soil Office. The results showed that in the commune of Satiri, the micro-basins are dominated by concretion leached tropical ferruginous soils (28.99%), shallow indurated leached soils (26.16%) and superficial indurated leached tropical ferruginous soils (22.80%). In the district of Koumbia, eight (08) soil types were identified, including superficial indurated leached tropical ferruginous soils (28.60%), shallow indurated leached tropical ferruginous soils (23.95%) and lowhumus hydromorphic soils with surface pseudogley (24.84%). Almost all the soils identified in Satiri showed an "medium" fertility level; while in Koumbia, 65.49% of soils had an "medium" fertility level and 30.28%, a "very low " fertility level. These results suggest that sustainable soil fertility management strategies can be implemented at the micro-watershed level.
Les représentations sociales de la ressource en eau dans un contexte de risques pathologiques à Mango (Togo)

Published: November 2024

La question de la préservation des ressources en eau constitue un défi  majeur pour de nombreuses localités. La ville de Mango, situé à l’extrême  nord du Togo, présente, à l’image d’autres agglomérations, de multiples  problèmes liés à la gestion de sa ressource en eau. La dynamique de gestion de la contamination de l’eau par des polluants chimiques, des  risques microbiologiques ou la radioactivité mise en évidence est dominée  par une logique de solution approximative : pas de traitement de fond des  problèmes mais des solutions techniques ou curatives pour en traiter les symptômes. L’objectif de la présente recherche est d’analyser les  différentes conceptions attachées à l’usage de l’eau. La démarche  méthodologique est de type qualitatif. Les données ont été collectée par  des entretiens individuels approfondis auprès des personnes ressources et  des groupes de discussion dans deux (02) quartiers de la ville que sont  Fomboro et Sangbana, sur un échantillon de 104 individus. Il ressort de  l’analyse des données que les pouvoirs publics, maître d’ouvrage, et les  bénéficiaires n’ont pas en commun un même rapport à l’ouvrage d’accès à  l’eau potable, et ne partagent pas les mêmes représentations de la gestion  locale de l’eau. Ce rapport à la ressource en eau est symptomatique d’une  gestion approximative de la source de captage d’eau potable à Mango.
