A Stabilized Finite Element Formulation of Non-Newtonian Fluid Model of Blood Flow in A Bifurcated Channel with Overlapping Stenosis
Authors: Norliza Mohd Zain  , Zuhaila Ismail  , Peter Johnston
Published: October 2021

A stabilized form of finite element formulation known as the Galerkin least-squares (GLS) method is implemented here for solving the two-dimensional incompressible non-Newtonian fluid model of blood flow in a diseased artery. The modelling for this type of flow is based on the conservation of mass and momentum equations, coupled with the generalised Newtonian liquid (GNL) constitutive equation characterized by the generalised power law (GPL) model. The flow of blood in this present study are assumed as steady, laminar and fully developed. The finite element algorithms considered herein are first solved for the Newtonian fluid in a straight artery with a bell shaped stenosis for validation purposes. As the efficiency and validity of the proposed algorithms are obtained through comparison with the findings from existing literature and COMSOL Multiphysics 5.2 software. Then, the algorithms are being implemented to the generalised power law fluid model of blood flow in a bifurcated artery with overlapping stenosis located at the parent's arterial lumen. The numerical results illustrate the arising of distinct sizes of vortex shedding downstream of the stenotic region for each generalised power law index.
Principe de différence et politiques fiscales
Authors: Desbiolles Blondine
Published: October 2021

Cet article examine les objections de Thomas Nagel au principe de différence. Quoiqu’il partage les thèses égalitaristes de Rawls, il relève des failles internes au principe de différence : il renforce des asymétries entre favorisés et défavorisés, est psychologiquement inacceptable pour des individus réels, et ne suffit pas à définir un système fiscal pleinement égalitariste. Nous présentons et discutons alors les analyses et propositions que Nagel avance sur le plan de la justice distributive et fiscale. Elles constituent des correctifs et prolongements de la théorie de Rawls, dans une perspective toutefois distincte : il s’agit non plus de définir la structure de base d’une société bien ordonnée, juste et équitable, mais de réaliser l’égalité dans une société démocratique actuelle.
Stratégies de localisation des entreprises commerciales et industrielles

Published: October 2021

Résumé Ce chapitre illustre comment la pensée intuitive des décideurs du commerce de détail peut être intégrée à l’aide de méthodes qualitatives dans l’évaluation des sites commerciaux. Il affirme que l’absence d’approches qualitatives dans les méthodes existantes a réduit leur portée utilitaire. Ce chapitre expose la structure d’un programme de recherche continu permettant de surmonter cette difficulté en intégrant des approches « hard » et « soft » à travers un système d’aide à la décision spatiale (SADS). L’étape initiale de ce processus implique l’appréhension de la perspicacité intuitive des responsables du commerce de détail concernant les facteurs qu’ils pensent influer sur la performance des superstores, représentant ces construits « soft » comme des cartes cognitives ou causales. Ce chapitre est illustré par quelques interviews de responsables d’une grande société de commerce à succursales multiples du Royaume-Uni afin de montrer comment les construits de décideurs individuels peuvent être appréhendés et intégrés. Une discussion est également proposée sur la manière dont la base de connaissances « soft » sera utilisée dans les étapes suivantes de la recherche. La deuxième étape impliquera l’établissement d’une représentation « hard » du processus d’évaluation du site, expliquée par des exemples utilisant des réseaux neuro-flous. Dans l’étape trois, cette représentation est incorporée dans un « moteur » de classification de magasins qui associe un nouveau site commercial avec des groupes discrets de magasins analogues. L’étape quatre construira un modèle de raisonnement spatial pour lier le moteur de classification aux données spatiales « hard » (déjà utilisées dans la plupart des systèmes organisationnels) et des construits spatiaux « soft » (à partir de la base de connaissances) suffisamment décomposés pour être mesurables, soit à partir d’ensembles de données spatiales existantes, soit à partir d’inputs provenant de l’analyste. L’étape finale de la procédure consistera à faire tourner et à calibrer le modèle. Plus largement, le chapitre illustre la valeur de synthèse entre la cartographie cognitive et des méthodes plus formelles dans la saisie et l’utilisation de la perspicacité intuitive à côté des données « hard ». Pour ce faire, le futur travail considérera toute une variété de techniques, incluant les réseaux neuro-flous, pour mettre en question les ensembles de données afin de rassembler la preuve analogue appropriée. L’approche serait ainsi d’une particulière utilité pour les décideurs.
Capital humain et dualisme sur le marché du travail
Authors: Dhyne Emmanuel , Mahy Benoît
Published: October 2021

Résumé L’objectif de ce chapitre est de voir dans quelle mesure les taux de chômage élevés, les faibles taux de réallocation et le développement potentiel d’un marché dual ont pu influencer les perspectives d’emploi des personnes entre 1994 et 96, et en retour si nos résultats sont compatibles avec les implications de l’existence de ce marché dual. Pour l’atteindre, nous déterminons des probabilités de transition entre différents statuts représentatifs du non-emploi, des bons (marché primaire) et de mauvais (secondaire) emplois en estimant des processus markoviens en temps discret sur des données du panel belge des ménages (P.S.B.H.). Différenciés par caractéristiques individuelles, nos résultats ne sont généralement pas incompatibles avec l’hypothèse de développement dual du marché, au détriment des femmes, des peu qualifiés, des wallons ou des jeunes, au sens où ceux-ci occupent davantage le segment secondaire. Par contre, l’implication de l’approche duale selon laquelle le marché secondaire serait plutôt perméable au non-emploi et imperméable au marché primaire n’est pas vérifiée comme telle par nos estimations. C’est davantage une autre dualité, entre emploi et non-emploi, qui serait observée au sens où peu de non-emploi ont accès à l’emploi.

Résumé L’objectif de cette communication est de présenter un panorama de la flexibilité du marché du travail en Belgique et dans ses régions au cours des dix dernières années et d’en dégager les tendances les plus marquantes. Partant d’un canevas théorique, nous structurons la flexibilité du travail en trois catégories : la flexibilité liée au contrat, la flexibilité de la durée du travail et la flexibilité liée à l’aménagement du temps de travail. Les données dont nous disposons mettent en évidence le caractère multidimensionnel de la flexibilité et sa diffusion à une partie croissante des emplois au cours des dix dernières années. Ce constat ouvre la voie à de nombreuses questions dont deux ont retenu notre attention, la mise en œuvre de la formation continue en entreprise et l’opportunité d’une diminution de la durée légale du travail.

Résumé Afin « d’adapter des travailleurs aux mutations industrielles, le Fonds social européen (FSE) soutient des projets, essentiellement de formation professionnelle, en Wallonie et à Bruxelles. Dans le cadre de l’évaluation des programmes du FSE, une enquête a été réalisée auprès des 200 promoteurs de projets. Celle-ci avait pour objectif d’apprécier la pertinence des actions développées aux objectifs fixés par les programmes. Le ciblage des formations sur les publics les plus fragilisés, le lien de celles-ci aux mutations industrielles, l’anticipation des changements dans les emplois ou les qualifications constituaient les principaux indicateurs de pertinence des formations. L’enquête a par ailleurs permis d’identifier plusieurs logiques de formation et de mettre en évidence celles qui, dans le contexte wallon et bruxellois, semblaient relever d’une démarche innovante.
La parole politique en confrontation dans les médias
Authors: Bovet Alain , Malbois Fabienne
Published: October 2021

Résumé La confrontation des analyses d’un débat télévisé et d’un talk show radiophonique en termes de cadre de participation permet de montrer des différences importantes mais aussi des convergences imprévues. Les différences portent sur le footing assigné aux intervenants : alors que le débat télévisé assigne un footing unique et ne tolère aucun jeu, le talk-show semble se définir par la multiplicité et la labilité des positions depuis lesquelles les participants sont appelés à parler. Dans les deux cas, ces rapports très distincts au cadre de participation vont pourtant de pair avec une configuration aussi rigide que conventionnelle de l’enjeu et des positionnements qui s’y rapportent. Ce constat invite à nuancer, par le biais d’un approfondissement de l’analyse du cadre de participation, les thèses selon lesquelles les mutations plus ou moins récentes de la parole publique médiatisée contribuent à un renouvellement des espaces publics démocratiques.

Résumé Nous analysons une séquence médiatico-politique au cours de laquelle le Président de la République française Nicolas Sarkozy affronte l’opposition qui manifeste contre sa politique anti-crise des subprimes . Il déploie une communication de crise composée de deux interventions télévisuelles (5 et 18 février 2009). Dans la première émission, à l’intérieur d’un format et d’un dispositif télévisuels soucieux des manifestants, le Président associe un comportement interactionnel d’écoute à une stratégie argumentative polémique : il plaint les manifestants tout en repoussant leurs exigences. La seconde émission est une simple allocution solennelle du Président : ce dernier annonce des mesures anti-crise sans renoncer à sa stratégie argumentative polémique. Dans cette séquence, le Président projette un éthos sensible qui devrait lui permettre de poursuivre sa politique d’avant la crise. Notre étude montre qu’il y a interaction directe entre le plan médiatique, le plan discursif, et les plans social et politique.
L’appropriation de la figure du zombie dans le cinéma coréen
Authors: Coppola Antoine
Published: October 2021

L’acclimatation de la figure du zombie dans le cinéma sud-coréen s’est confrontée à un imaginaire horrifique traditionnel réfractaire. Pourtant, les zombies se sont peu à peu imposés avec des films à succès qui ont touché un large public à partir des années 2010 ( Train to Busan , Peninsula ). La coréanisation du zombie n’est cependant sans effets : en reproduisant le passage, réalisé en Occident, du zombie transcendantal (liés aux esprits de la métaphysique) au zombie immanent (corporalisé et « naturalisé ») pouvant être utilisé comme métaphore au service d’une critique sociale (clivages sociaux, aliénations industrielle et communicationnelle), un changement de paradigme de l’imaginaire coréen se fait jour. La famille, particulièrement mise en scène dans ces films, et sa sacralisation traditionnelle sont particulièrement touchées. Au-delà de son caractère subversif au niveau socio-politique, le zombie coréen, dans sa nouvelle nature, après être passé par une forme hybride avec le fantôme traditionnel, annonce un être futuriste post-humain, issu de l’homme mais sans l’humanité.

Prediction of post-induction hypotension in young adults using ultrasound-derived inferior vena cava parameters: An observational study
Authors: Mohammed Sadik , Syal Rashmi , Bhatia Pradeep , Chhabra Swati , Chouhan Ravindra S , Kamal Manoj
Published: October 2021

Background and Aims:

Inferior vena cava (IVC) diameter and its respiratory variability have been shown to predict post-induction hypotension with high specificity in a mixed population of patients. We assessed whether these parameters could be as reliable in healthy adult patients as in a mixed patient population.

Methods:

In the present prospective observational study, 110 patients of either sex, aged between 18 and 50 years, belonging to American Society of Anesthesiologists class I and II, fasted as per the institutional protocol and scheduled for elective surgery under general anaesthesia were enroled. Prior to induction, ultrasound examination of IVC was done and variation in IVC diameter with respiration was assessed. Maximum and minimum IVC diameters [(dIVCmax) and (dIVCmin), respectively] over a single respiratory cycle were measured and collapsibility index (CI) was calculated. Vitals were recorded just before induction and at every minute after induction for 10 min. Episodes of hypotension (mean arterial pressure [MAP] <65 mmHg or fall in MAP >30% from baseline) during the observation period were recorded. The receiver operating characteristic (ROC) curve was constructed for determining optimum cut-off with sensitivity and specificity of IVC diameters and CI for development of hypotension.

Results:

IVC was not visualised in 22 patients. Out of the remaining 88 patients, 17 (19.3%) patients developed hypotension after induction. The dIVCmax, dIVCminand CI were comparable between patients who developed and who did not develop hypotension. The area under curve of ROC for CI, dIVCmaxand dIVCminwas 0.51, 0.55 and 0.52, respectively, with optimum cut-off value of 0.46, 1.42 and 0.73, respectively.

Conclusion:

Ultrasound-derived IVC parameters demonstrate poor diagnostic accuracy for prediction of hypotension after induction in healthy adult patients.
Point-of-Care Ultrasound (POCUS) for the assessment of volume status and fluid management in patients with severe pre-eclampsia: A systematic review and meta-analysis
Authors: Bajwa Sukhminder Jit Singh , Kurdi Madhuri S. , Sutagatti Jagadish G. , Bajwa Sukhwinder K. , Theerth Kaushic A.
Published: October 2021

Background and Aims:

Appropriate volume assessment and fluid management can prevent maternal deaths in the severely pre-eclamptic (SPE) parturients. We planned a systematic review and meta-analysis (MA) to evaluate the role and ability of point-of-care ultrasound (POCUS) in the assessment of volume status and early detection of lung oedema in an SPE parturient.

Methods:

An e-literature search was done from several databases. Data were extracted under five domains including POCUS-derived parameters like echo comet score (ECS), lung ultrasound (LUS) scores, B-patterns, optic nerve sheath diameter (ONSD), E/e’ ratio, presence of pleural effusion, pulmonary interstitial syndrome and pulmonary congestion. The risk of bias was assessed. Extracted data were analysed using MetaXL and Revman 5.3. Heterogeneity in the studies was evaluated using the Cochrane Q test and I2statistics. Funnel plots were used for the assessment of publication bias.

Results:

Seven prospective studies including 574 parturients (including 396 pre-eclamptics) were selected. POCUS included lung, optic nerve, cardiac and thoracic US. In two studies, the ECS and LUS scores pre-delivery were higher in pre-eclamptics. Two studies found a mean ONSD of 5–5.84 mm before delivery. MA revealed a significantly lower mean ECS score at post-delivery than pre-delivery, and the summary prevalence of B-pattern and pleural effusion among SPE parturients was found to be 0.28 (0.03–0.84) and 0.1 (0–0.2), respectively. A good correlation was observed between B-line patterns and diastolic dysfunction (increased E/e’ ratio), LUS score and thoracic fluid content, ONSD and ECS in individual studies.

Conclusion:

POCUS parameters can be useful as early markers of fluid status and serve as useful tools in the precise clinical management of pre-eclampsia.
Risk of Hepatic Toxicity and Drug Response in Patients with Chronic Suppurative Otitis Media
Authors: Rafi SM Tariq , Mehboob Shafaque , Mejabeen  , Tariq Naila , Khan Hurithmina , Mehboob Moona
Published: October 2021

Objective:

The aim of the current study was to evaluate the risk of hepatic and renal toxicity in patients with chronic suppurative otitis media (CSOM) and the effects of antibiotics (ciprofloxacin and co-amoxicillin) on it.

Methods:

This is a case–control study conducted on patients and healthy volunteers divided into four groups; G1 (negative control), G2 (positive control), G3 (patients treated with ciprofloxacin), and G4 (patients treated with co-amoxicillin). The study was conducted in Jinnah Postgraduate Medical College in Karachi, Pakistan, from May 2018 to October 2018.

Results:

There was a significant (P < 0.05) increase in total bilirubin, direct bilirubin, alkaline phosphatase, Serum glutamic pyruvic transaminase (SGPT), and Gamma-glutamyl transferase (GGT) in patients of G2 (positive control) as compared to G1 (negative control). However, the treatment with antibiotics may recover the normal liver enzyme levels except direct bilirubin and SGPT. An insignificant increase in blood glucose levels and urea was found in G2, G3, and G4 with insignificant increased creatinine levels.

Conclusion:

Hepatic toxicity may be induced in patients with CSOM, particularly if not properly treated. Therefore, precautions with proper follow-up of liver function test should be taken in CSOM.
Effectiveness of Intratympanic Dexamethasone as Salvage Therapy in Treating Sudden Sensorineural Hearing Loss
Authors: Gyawali Bigyan Raj , Pradhanaga Rabindra Bhakta , Rayamajhi Pabina
Published: October 2021

Introduction:

The steroid is the drug of choice in patients with sudden sensorineural hearing loss (SSNHL). Thirty to fifty percent of cases, despite receiving steroids may have incomplete recovery. Furthermore, there are a significant number of patients in whom systemic steroids are contraindicated such as cases with uncontrolled diabetes, uncontrolled hypertension, and pregnancy. Intratympanic steroids can play a vital role as salvage therapy in these cases. The aim of this study was to evaluate the effectiveness of intratympanic Dexamethasone as salvage therapy in cases who fail to respond with systemic steroids, who present late (>1 week) after the onset of symptoms and cases, in whom systemic steroids are contraindicated.

Materials and Methods:

This was a retrospective study conducted in the Department of ENT-Head and Neck Studies, T.U. Teaching Hospital, Kathmandu, Nepal. Approval from the Institutional Review Committee was taken. A prospectively set record data of cases with SSNHL receiving intratympanic Dexamethasone as a salvage therapy from April 2018 to April 2020 were analyzed for improvement in hearing outcome. We used SPSS version 25 for the statistical analysis. Chi-square test and Fisher's exact test were used to draw statistical co-relation. Value of P < 0.05 was considered statistically significant.

Results:

A total of 34 cases met the inclusion criteria. M: F was 3:1 with the majority of cases in the third–fifth decades of life. A total of 11 cases showed partial improvement and one case had complete improvement. There was no statistically significant co-relation between hearing outcome and time interval (from the onset of symptoms to intratympanic injection), level of hearing loss, comorbidities, and prior use of systemic steroid therapy (P > 0.05).

Conclusion:

Intratympanic Dexamethasone has audiological benefits as a salvage therapy in cases with SSNHL failing to respond with systemic steroid therapy.
Conducting Fukuda Stepping Test in a Noisy Clinic and the Effects of Sound
Authors: Teh Carren Sui Lin , Gima Erica Anak , Mamat Hani Binti , Lye Meng Hon , Din Sobani Bin , Prepageran Narayanan
Published: October 2021

Context:

The Fukuda stepping test (FST) is used to assess the labyrinthine function via the vestibulospinal reflex. The test is meant to be conducted in a quiet room, but in a busy clinic setting, it is often performed in the clinic itself, and individuals are exposed to environmental sounds.

Aims:

The aim of this study was to assess the effects of environmental sounds and the effects of fixed directional sound on the outcome of FST.

Settings and Design:

This is an observational study.

Subjects and Methods:

Thirty healthy participants performed the FST in the otorhinolaryngology clinic, in a sound-treated room, and then in a sound-treated room with the presence of a fixed directional sound where the angle of rotation, angle of displacement, and distance of displacement were compared.

Statistical Analysis Used:

Independent t-test and Chi-squared test were used for statistical analysis.

Results:

There was no statistical difference in the angle of rotation and angle of displacement in all three settings. Although the mean distance of displacement was above 50 cm in all three settings, there was a significant reduction between clinic versus sound-treated room (P = 0.016) and clinic versus room with sound-treated directional sound (P = 0.002). Fixed directional sound had no significant influence on the direction of rotation in all the participants.

Conclusions:

Performing FST in the standard clinic will not affect the results. Concurrently, we suggest omitting measurement of the distance of displacement in FST as it is not reproducible in our normal sample and is highly susceptible to auditory cues but to focus on the angle of rotation.
Impact of the COVID-19 pandemic on the management of surgical patients presenting in an emergency setting -Report from a tertiary referral centre
Authors: Deshpande AA , Das AA , Deotale SB , Takalkar YP
Published: October 2021

Introduction:

At the onset of the first wave of COVID-19 pandemic, the publications on managing surgical emergencies were sparse. Health care personnel were facing an unprecedented problem with limited information. On this background, we have reviewed the operational challenges faced and the protocols followed by us while managing emergency surgical patients. The clinical presentations, RT-PCR testing rates, trend of COVID-19 positivity in emergency surgical patients and its comparison to the general population, swab positivity among screen positive and negative patients, grade of COVID-19 affection, the outcomes in emergency surgical patients, and COVID-19 affection in treating personnel is studied.

Patients and Methods:

A protocol for triaging patients at presentation into screen positive or negative for COVID-19 was instituted. A proforma for all admitted patients over the period of March 2020 to August 2020 was maintained. A retrospective review of this data was carried out after Institutional Ethics Committee permission.

Results:

A total of 222 patients presented to the surgical emergency, of which 110 required admission. Of the admitted patients, 28 were COVID-19 positive. The positivity amongst admitted and operated patients increased to 50% and 66.67%, respectively in August. The difference in mortality rate amongst the operated COVID-19 positive (11.1%) and negative (14.28%) patients was nonsignificant. None of the treating doctors had to be quarantined during this period.

Conclusions:

The number of COVID-19 positive patients rose serially over the study period. The outcome was not affected by the COVID-19 status in mild cases. A high rate of COVID-19 positivity was seen in patients requiring emergency surgery. Universal precautions ensured delivering treatment to emergency patients in standard time. Testing should continue for all as screening alone is not effective as the virus spreads into the population. Proper protocols helped us to protect the health care workers.
Radiological aspects during cutting and removal of L-08 coolant channel from the core of 540 MWe TAPS-4 nuclear reactor

The pressurized heavy-water reactors (PHWR) consist of a low-pressure horizontal reactor vessel, calandria, containing heavy water as moderator. The calandria is pierced by a large number of coolant tubes (also called pressure tubes [PTs], 392 in 540 MWe PHWR), which contains fuel bundles, and through which pressurized heavy-water coolant circulates. During biennial shut down in 2017, in-service inspection of coolant channels in Tarapur atomic power station-4 (TAPS-4) had been carried out and after the review of results of inspection, it was recommended by various groups of experts that channel L-08 should be removed for postirradiation examination at Bhabha Atomic Research Center (BARC). Before the channel removal job, one special shielding flask was designed to shift the removed channel to BARC. The integrity test of special shielding flask was carried out by safely placing cobalt-60 (source strength 851000 MBq) capsule source inside the shielding flask with the help of cranking unit mechanism followed by dose rate mapping on the outer surface of the flask. To establish the hydrogen pickup rates in L-08 PT, sliver samples were collected and separately sent to BARC. Four metallic sliver samples were obtained at four different distances from north E-face. The activity content present in each sliver sample was also estimated. The maximum activity estimated was 2313.24 MBq. Subsequently, L-08 coolant channel was cut from both sides using a chipless tool. Jobs involving heavy water (D2O) collection work were carried out with a ventilated plastic suit. Derived air concentration (DAC) of tritium at the work location was maintained below 1DAC during the entire activity. Particulate DAC was found below the detectable limit. Floor contamination checks and floor decontamination were conducted at regular intervals to avoid buildup of contamination. As a result of such high-quality radiological safety measures, only 25 workers, out of 270 radiation workers, have received a cumulative dose of more than 3 mSv in direct reading dosimeter with a maximum individual dose of 8.45 mSv and maximum individual uptake of 0.39 GBq/m3. Job was completed with a total collective dose of 324.35P-mSv which is 14.5% lower than estimated. This article highlights some of the critical tasks involved in the cutting and the removal of irradiated coolant channel from the core of 540 Mwe TAPS-4 reactor which is a first of kind activity in nature.

Due to its voluntary and unburdening character, game is an excellent medium for learning. Children learn through games, because on the basis of rules, settings and their own skills, they understand the existing and define new concepts and relations between them. The game meets one important requirement of education – straightening multiple skills at the same time. Learn- ing mathematics is a challenge for many students, so the game seem like a good solution to bring mathematics closer to students. Mathematical games encourage strategic thinking, problem solving and develop logical thinking. Combining play as a form of learning with ICT progress, computer games became a new teaching tool. Video games are a much better representative system for learning mathematics than symbolic representations on static pages of textbooks.
TEORIAS DO DESENVOLVIMENTO SOB A PERSPECTIVA DO INVESTIMENTO E DO ESTADO

O crescimento econômico é um dos motores do desenvolvimento, contudo, sua
concretização deriva da acumulação de capital proveniente do investimento produtivo,
que por sua vez, depende de circunstâncias nem sempre encontradas nas economias,
sobretudo, nas pouco desenvolvidas. Os fenômenos inerentes ao próprio desenvolvimento
criam forças centrípetas que concentram regionalmente o processo de acumulação,
gerando desigualdades no curto prazo e incertezas no longo prazo. Uma solução para
correção das distorções entre mercados desenvolvidos e os pouco desenvolvidos é

CHALLENGES FACED BY GIRLS IN THE COURSE OF THEIR SECONDARY SCHOOL EDUCATION
Authors: Mutuku Magdalena Mueni , Njeru Enos , Mburugu Edward
Published: October 2021

Purpose: The purpose of this study was to identify the challenges faced by girls in the course of their secondary school education.

Methodology: This study utilized the exploratory research design. The study targeted specific girls within the secondary schools and those who dropped out of school aged between 14-24 years in the last four years. The sample was drawn from form two, form three and forms four secondary students. Data was generated from both secondary and primary sources. Purposive sampling was applied to get the division and the district in which units of observation have the required characteristics. The three schools in Chuluni division purposively selected were Kaluva Mixed day and boarding secondary school, Mbitini mixed day secondary school and Mbitini girls' secondary school. Snowball sampling was used to reach girls out of school. The study targeted specific girls within the secondary schools and those who dropped out of school aged between 14-24 years in the last four years. It also targeted, teachers, parents and education officer in the secondary schools in Chuluni Division The tool for data collection was a set of semi-structured questionnaires specifically designed for the students in and out of school. A key approach adopted by the study was Focus Group Discussion (FGD) supplemented by in-depth interviews and also the study made use of direct observations that were guided by observation guide or checklist. Furthermore, inferential and descriptive statistics were used for data analysis. Data were coded and entered into the computer for analysis using Statistical Package for Social Sciences, version 23.

Results: The girls out of school indicated that they had dropped out of school due to financial constraints. Additionally, due to poverty parents fail to support the girl child through secondary school education in preparation for higher education. This makes this group of young girls face the risk of early sexual exposure, early marriage and sexual abuse.

Unique contribution to theory, practice and policy: The study findings validates the Theory of liberal feminist that all sexes should be treated with equality.  The government should embark on ensuring that policies do not discriminate against girls and women - in education, in employment or in gaining access to leadership positions. Measures should be put in place to create a balance in favor of girls - by offering scholarships or school feeding programmers, through making schools girl-friendly with proper and separate sanitation, by employing more women teachers for the security of girls and as role models.
ELUSIVE QUEST BY WOMEN FOR LEGISLATIVE NUMBERS IN KENYA’S NATIONAL ASSEMBLY OF THE 11TH PARLIAMENT (2013 -2017)
Authors: Miruka Simon , Ngare Grace , Okemwa Pacificah
Published: October 2021

Purpose: Application of gender quotas in the 2013 general elections in Kenya led to 68 women legislators joining the National Assembly. This was the largest number of women elected to the legislature since independence in 1963. Studies show that such surges embolden women to pursue legislative agenda on gender equality and social welfare issues. This article examines women legislators’ quests for further increased numbers in Kenya’s National Assembly 2013 -2017 and the results.  

Methodology: This was a descriptive study of Kenya’s National Assembly of the 11th parliament (2013 -2017). A total of 11 women and four key informants were identified through stratified and purposive sampling respectively. Data was collected using semi-structured interview schedules. Responses were recorded in writing and audio-tape. The study also did a content analysis of the Hansard. Data was transcribed, manually processed, analysed and discussed under each study objective. Quantitative data was captured in tables with descriptions while qualitative data was narrated with inferences.

Findings: The study established that efforts to increase women’s numbers in the legislature were unsuccessful because of resistance from male colleagues. However, women achieved an increase in committee membership and leadership. The article concludes that resistance to the proposed affirmative law to increase women’s legislative numbers was rooted in patriarchy and male entitlement to power.

Unique contribution to theory, practice and policy: The article demonstrates how the quest to embed affirmative action in law was frustrated by patriarchy. It states that for women to succeed on such pursuits, they need to be assertive and strategic. It further demonstrates that women’s occupation of parliamentary leadership positions enabled them to showcase their abilities and debunk the notion that they are inferior. This coheres with liberal feminism, that marginalising women denies the society the benefit of their talents. The article proposes that women should seek influential parliamentary committees instead of seeking a general spread in all of them. A constitutional amendment to have an unequivocal provision on elections that automates the desired proportions of women to men in the National Assembly is also recommended.

Purpose: Akurinu community demonstrates the resoluteness and innovative originality of an African religious movement that in the context of a congested and contested religious space, where western Christianity has, with immense success, obliterated African cultural and religious beliefs to substitute them with foreign ones, this church remains stable. The general objective of the study was to examine the spread of the Akurinu religious movement

Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps.

Findings: The study concludes that transformation changed the Akurinu way of life and practices such that they relaxed their dietary rules and could now eat in hotels, took active roles in politics, started seeking medical attention in hospitals and embraced formal education. Indeed, Akurinu became a church with well-organized leadership structures and operations. In this transformation, the Akurinu church conformed to a modernization crisis that demanded a search for new social adjustments and identities outside their traditional world mileu. However, there were sections of Akurinu who remained conservative and could not for instance visit hospital or seek medical attention from a doctor, as they believed in faith healing, while others could not participate in any political activity, like voting or vying for elective posts.

Recommendations: The study recommends that the Akurinu church will have to rediscover their prophetic calling which dares to anticipate the future and step out towards it by faith. There is an urgent need to rediscover a refinement of what it means to be a Mukurinu in the context of a global world of change.

This study aimed to compare the electrical characteristics of mineral oil-based nanoparticles to those of pure mineral oil. Mineral oil used in distribution transformers was mixed with aluminum oxide (Al2O3) nanoparticles, which serve as an insulator, with 0.01, 0.03, and 0.05 % mineral oil volume concentrations. The moisture content in mineral oil was measured beforehand, and the electrical tests were subsequently conducted in accordance with international standards. The moisture content test revealed that the combination of nanoparticles and mineral oil resulted in an increase in moisture content. As regards the test of AC withstanding voltage and negative polarity lightning impulse voltage, it was found that the mineral oil mixed with the nanoparticles had higher dielectric strength than the original mineral oil. In addition, the test results of positive polarity lightning impulse voltage demonstrated that with a mixture of mineral oil and the nanoparticles at a 0.01 % concentration, the positive polarity lightning impulse dielectric strength of the mineral oil increased. However, at concentrations of 0.03 and 0.05 %, it did not rise, regardless of the increasing volume of nanoparticles. The results, thus, showed promising directions for applications of nanoparticles in the development of electrical properties of mineral oil.
HIGHLIGHTS

The addition of Al2O3 nanoparticles to the mineral oil resulted in an increase in the oil moisture content. However, it was found that the moisture content in the mineral oil tended to decrease with the increase in the amount of nanoparticles
The optimum nanofluid combination in terms of increased AC breakdown strength was created by adding Al2O3 nanoparticles to mineral oil at a rate of 0.05 vol%
The Al2O3 nanoparticles being added to the mineral oil can give an increase in the impulse breakdown voltage with the negative polarity
For the positive polarity of the impulse breakdown voltage, the best nanofluid mixture in terms of increased breakdown strength was produced by the addition of Al2O3 nanoparticles at a rate of 0.01 vol% to the mineral oil

Unconscious or informal application and failure to acknowledge the use of operations research (OR) approach by corporate managers has been going on globally for a very long time. This largely accounts for the inability of scholars to make accurate assessment of the level of application of operations research in the non-academic environment. It is therefore evident that asking an operations manager whether OR models or methodology is applied by his company may likely not produce a response that truly represents reality as some may be unknowingly making such applications. This study therefore examined the level of awareness of OR among corporations in the Nigerian manufacturing sector. It also assessed the extent of familiarity with OR models among managers in the manufacturing sector and their appreciation of OR techniques as a viable business decision-making tool. Consequently, steps that constitute the decision-making procedure of firms in the manufacturing industry of Nigerian economy were examined to determine the extent to which OR methodology or philosophy may have been incorporated.

This paper aims at investigating the effects of organizational communication on the organizational commitment, emphasizing the importance of communication. This study provides an empirical effort into a very limited research on the effects of sub-concepts of communication which is one of the organizational and task-based factors that are the determinants of organizational commitment on organizational communication. Data related to the research has been collected through internet and face-to-face surveys. This research has been conducted in Istanbul province with the employees from various sectors, mainly service sector employees. Data collected by 215 survey participants in January 2014 has been transferred to SPSS program and tested by means of Cronbach’s alpha reliability test, correlation analysis and regression analysis. Results show that there is a partial effect of organizational communication style on the organizational commitment; other types of organizational communication have no impact on organizational commitment. These findings indicate that organizational commitment of the employees, in the service sector mainly, are affected by the communication styles of their managers. The reason for that is human labor emerges as a main factor in this sector and they need to be allocated more time for communication by their managers since the sector offers working opportunities under the difficult conditions and managers influence employees and employees perform their work and behave in a way they are affected by their managers. These findings also indicate that some variables might affect organizational commitment in a sector and others might not. Organizational problems/results about the communication might differentiate from one sector to another. Discussion and managerial implications are also presented in the study.
