In 2021, an operational research study in two tertiary hospitals in Freetown showed poor hand hygiene compliance. Recommended actions were taken to improve the situation. Between February–April 2023, a cross-sectional study was conducted in the same two hospitals using the World Health Organization hand hygiene tool to assess and compare hand hygiene compliance with that observed between June–August 2021. In Connaught hospital, overall hand hygiene compliance improved from 51% to 60% (p < 0.001), and this applied to both handwash actions with soap and water and alcohol-based hand rub. Significant improvements were found in all hospital departments and amongst all healthcare worker cadres. In 34 Military Hospital (34MH), overall hand hygiene compliance decreased from 40% to 32% (p < 0.001), with significant decreases observed in all departments and amongst nurses and nursing students. The improvements in Connaught Hospital were probably because of more hand hygiene reminders, better handwash infrastructure and more frequent supervision assessments, compared with 34MH where interventions were less well applied, possibly due to the extensive hospital reconstruction at the time. In conclusion, recommendations from operational research in 2021 contributed towards the improved distribution of hand hygiene reminders, better handwash infrastructure and frequent supervision assessments, which possibly led to improved hand hygiene compliance in one of the two hospitals. These actions need to be strengthened, scaled-up and guided by ongoing operational research to promote good hand hygiene practices elsewhere in the country.
Non-Local Interactions Are Essential Elements for Dark Matter Halo Stability: A Cross-Model Study
Authors: Borzou Ahmad
Published: August 2023

This paper introduces a comprehensive methodology for examining the stability of dark matter (DM) halos, emphasizing the necessity for non-local inter-particle interactions, whether they are fundamental or effective in nature, to maintain halo stability. We highlight the inadequacy of vanilla cold, collisionless DM models in forecasting a stable halo without considering a “non-local” interaction in the halo’s effective free energy, which could potentially arise from factors like baryonic feedback, self-interactions, or the intrinsic quantum characteristics of dark particles. The stability prerequisite necessitates significant effective interactions between any two points within the halo, regardless of their distance from the center. The methodology proposed herein offers a systematic framework to scrutinize the stability of various DM models and refine their parameter spaces. We deduce that DM halos within a model, where the deviation from the standard cold, collisionless framework is confined to regions near the halo center, are unlikely to exhibit stability in their outer sectors. In our study, we demonstrate that the issue of instability within DM halos cannot be addressed adequately using perturbative quantum effects. This issue is less pronounced for fermionic DM but suffers from a higher degree of severity when considering bosonic DM. We find that halos made of bosons with notable quantum effects have sharp edges, while those made of fermions show more diffuse boundaries extending toward infinity. To present the potentials of the cross-model approach, we explore the broadest form of the effective free energy around a chosen mass profile. Next, as a case study, we employ a model where the deviation from the standard cold, collisionless DM model is represented by a two-body interaction in the effective free energy to show how to use observations to investigate universal classes of DM models.
Primordial Planets with an Admixture of Dark Matter Particles and Baryonic Matter
Authors: Kiren O. V. , Kenath Arun , Sivaram Chandra
Published: August 2023

It has been suggested that primordial planets could have formed in the early universe and the missing baryons in the universe could be explained by primordial free-floating planets of solid hydrogen. Many such planets were recently discovered around the old and metal-poor stars, and such planets could have formed in early epochs. Another possibility for missing baryons in the universe could be that these baryons are admixed with DM particles inside the primordial planets. Here, we discuss the possibility of the admixture of baryons in the DM primordial planets discussed earlier. We consider gravitationally bound DM objects with the DM particles constituting them varying in mass from 20 to100 GeV. Different fractions of DM particles mixed with baryonic matter in forming the primordial planets are discussed. For the different mass range of DM particles forming DM planets, we have estimated the radius and density of these planets with different fractions of DM and baryonic particles. It is found that for heavier-mass DM particles with the admixture of certain fractions of baryonic particles, the mass of the planet increases and can reach or even substantially exceed Jupiter mass. The energy released during the process of merger of such primordial planets is discussed. The energy required for the tidal breakup of such an object in the vicinity of a black hole is also discussed.

Lower respiratory tract infections (LRIs) are a significant cause of disability-adjusted life-years (DALYs) across all age groups, especially in children under 9 years of age, and adults over 75. The main causative agents are viruses, such as influenza and respiratory syncytial virus (RSV). Viral LRIs in adults have historically received less attention. This study investigated the incidence of RSV and influenza in adult patients admitted to a referral hospital, as well as the clinical profile of these infections. Molecular testing was conducted on nasopharyngeal samples taken from a respiratory surveillance cohort comprising adult (15–59 years) and elderly (60+ years) hospitalized patients who tested negative for SARS-CoV-2, to determine the prevalence for influenza and RSV. Influenza was found to be less frequent among the elderly. The main symptoms of RSV infections were cough, fever, dyspnea, malaise, and respiratory distress, while headache, nasal congestion, a sore throat, and myalgia were most frequent in influenza. Elderly patients with RSV were not found to have more severe illness than adults under age 60, underscoring the importance of providing the same care to adults with this viral infection.
BET Inhibitor JQ1 Attenuates Feline Leukemia Virus DNA, Provirus, and Antigen Production in Domestic Cat Cell Lines

Published: August 2023

Feline leukemia virus (FeLV) is a cosmopolitan gammaretrovirus that causes lifelong infections and fatal diseases, including leukemias, lymphomas, immunodeficiencies, and anemias, in domestic and wild felids. There is currently no definitive treatment for FeLV, and while existing vaccines reduce the prevalence of progressive infections, they neither provide sterilizing immunity nor prevent regressive infections that result in viral reservoirs with the potential for reactivation, transmission, and the development of associated clinical diseases. Previous studies of murine leukemia virus (MuLV) established that host cell epigenetic reader bromodomain and extra-terminal domain (BET) proteins facilitate MuLV replication by promoting proviral integration. Here, we provide evidence that this facilitatory effect of BET proteins extends to FeLV. Treatment with the archetypal BET protein bromodomain inhibitor (+)-JQ1 and FeLV challenge of two phenotypically disparate feline cell lines, 81C fibroblasts and 3201 lymphoma cells, significantly reduced FeLV proviral load, total FeLV DNA load, and p27 capsid protein expression at nonlethal concentrations. Moreover, significant decreases in FeLV proviral integration were documented in 81C and 3201 cells. These findings elucidate the importance of BET proteins for efficient FeLV replication, including proviral integration, and provide a potential target for treating FeLV infections.

Background: Vaccine hesitancy has been identified by the World Health Organization (WHO) as a major worldwide health threat. Home Health Care (HHC) service recipients represent a vulnerable group and were prioritized to receive coronavirus disease (COVID-19) vaccination during the national vaccine campaigns in Saudi Arabia. We aimed to investigate the most frequent reasons for vaccine hesitancy among home health care recipients in Saudi Arabia. Methods: This cross-sectional survey was conducted among home health care (HHC) service recipients in Saudi Arabia from February 2022 to September 2022. The behavioral and social drivers (BeSD) model developed by the WHO was used to understand the factors affecting vaccination decision making in our cohort. Results: Of the 426 HHC service recipients enrolled in the study, a third were hesitant to complete the COVID-19 vaccination series. The most prevalent reported reason for COVID-19 vaccine refusal was concerns about the vaccine side effects (41.6%). Factors independently associated with COVID-19 vaccination hesitancy were: having chronic conditions (odds ratio [OR] = 2.59; 95% confidence interval [CI] = 1.33–5.05, p = 0.005), previous COVID-19 diagnosis (OR = 0.48; 95% CI: 0.28–0.82, p = 0.008), ease of getting the COVID-19 vaccine by themselves (OR = 0.49; 95% CI: 0.28–0.89, p = 0.018), belief in the importance of COVID-19 vaccine in protecting their health (OR = 0.60; 95% CI: 0.38–0.96, p = 0.032), and confidence in the safety of COVID-19 vaccination (OR = 0.38; 95% CI: 0.21–0.69, p = 0.001). Conclusion: Only one-third of the study participants were hesitant to complete the series of COVID-19 vaccination. Understanding the factors underpinning vaccine hesitancy among this group would help healthcare workers and policymakers in developing personalized health awareness campaigns aimed at improving vaccine acceptance levels.

Recently, numerous studies have been devoted to describing the heterogeneity of Alzheimer's disease (AD). The aim of our work was to study the clinical, biochemical, and neuropsychological signs of AD depending on the form of the disease. The study involved 173 patients with AD, of whom 65 patients with early onset and 108 with late onset at the stage of moderate cognitive impairment. All study participants underwent the Montreal Cognitive Assessment Scale (MoCA test), the Free and Cued Selective Reminding Test with Immediate Recall (FCSRT-IR), and a lumbar puncture with the determination of the levels of Aβ42 and Aβ40 biomarkers in the cerebrospinal fluid by enzyme immunoassay. The mean age of the patients with early onset of AD was 65.1±0.3 years, and with late onset - 78.6±0.5 years. According to our data, it was found that the majority of the patients with late-onset AD had a longer education (p=0.000) and had coffee more often (p=0.000) than the study participants with early onset of AD. We did not reveal the effect of alcohol and smoking on the neurodegenerative process. The patients with early-onset AD scored lower on the MoCA test than those with late-onset AD (p=0.000). The results of free recall and cue index on the FCSRT-IR test in the patients with late AD were significantly lower than in the patients with early AD onset (p<0.001). We found that the level of Aβ42 and the ratio of Aβ42/Aβ40 in the cerebrospinal fluid was significantly lower (p=0.000) in the patients with early AD onset. The results of our study prove the need for an integrated approach to diagnosing AD using clinical, neuropsychological,and biochemical research methods.

« La biographie profonde » de Barba Jacob par Fernando Vallejo. Relation biographique

« La biografia profunda de Barba Jacob por Fernando Vallejo. Relación biográfica ».

En El mensajero, la biografia del poeta Porfirio Barba Jacob (Colombia, 1883-1942) escrita por el escritor colombiano Fernando Vallejo, el género biográfico se déclina como una mezcla de erudición, de creatividad literaria y de intuición sicológica (Dosse, 2005). Erudición por la abundancia de la información recogida y el conocimiento de los textos, archivos como de la correspondencia del poeta. Creatividad literaria por el arte narrativo de Fernando Vallejo en un trabajo que se présenta como la anticipación o genesis de su posterior obra novelistica. En fin, intuición sicológica por el deseo fundador del autor de comprender la vida de un hombre que, segûn el mismo autor, contiene de alguna manera la suya.

Fernando Vallejo dedicó diez anos de su vida a la biografia de Miguel Angel Osorio, nombre de pila del poeta. Cabe suponer que dicho deseo de parte del biógrafo es animado por una empatia, por una implicación subjetiva en la que su propia autobiografia se entrevera con la construcción misma de su objeto biográfico. Fernando Vallejo, biógrafo, y futuro novelista, propende a la bûsqueda de si mismo en una relación especular con Barba Jacob a través del relato de su vida, como también se enfrenta con sus propias aporias existenciales, autobiográficas a partir de las preguntas sobre el poeta. Martine Boyer habla de «relación biográfica» (Boyer, 2005).

En este sentido este articulo establece una série de correspondencias o correlaciones entre la vida de Barba Jacob y la de Fernando Vallejo que van desde sus origenes comunes, pasando por su relación con el mundo y con Colombia, los pliegos de peticiones que cada uno formulara a su pais y a sus contemporáneos en cuanto al reconocimiento y a la valoración de sus obras haciendo del ataque y la polémica las más preciadas de sus armas.

Además, muestra cómo a través de la construcción de un héroe negative lejos de todo ideal ejemplarizante de tipo moral, Fernando Vallejo se construye con Barba Jacob una identidad común de «poetas malditos», de «reaccionarios», en la libertad absoluta de afirmarse a contracorriente de las ideas dominantes y de los valores ideológicos validados en los pianos institucional, politico, moral y literario de la época de cada uno.

Introduction: Sodium-glucose cotransporter-2 (SGLT2) inhibitors are a new diabetes treatment. Considering the prescription of these medicines for kidney transplant patients, this systematic review and meta-analysis aimed to investigate the impact of SGLT2 inhibitors on kidney transplant patients. Material and Methods: This meta-analysis study was performed based on the PRISMA guideline. The necessary data were collected by searching the databases of Scopus, PubMed, Cochrane, Google Scholar search engine, and Web of Science without a time limit until March 1, 2023. The data were analyzed in STATA 14. A P value less than 0.05 was considered significant. Results: The authors assessed eight articles with a sample size of 960 patients. The SGLT2 inhibitors showed no significant impact on levels of estimated glomerular filtration rate [SMD: -0.21 (95% CI: -0.65, 0.25)], serum creatinine [SMD: -0.02 (95% CI: -0.19, 0.15)], plasma hemoglobin A1c (HbA1c) [SMD: -0.62 (95% CI: -1.43, 0.18)], systolic blood pressure [SMD: -0.64 (95% CI: -1.80, 0.52)], and diastolic blood pressure [SMD: -0.64 (95% CI: -1.41, 0.14)], and on the patient’s weight [SMD:-0.31 (95% CI: -0.80, 0.18)]. Patient age did not influence the impact of SGLT2 inhibitors on estimated glomerular filtration rate (50–59 years-old age group: [SMD: 0.13 (95% CI: -0.04, 0.30)], 60–69 years-old age group: [SMD: -0.56 (95 % CI: -1.38, 0.26]). Duration of medicine use did not affect the impact of SGLT2 inhibitors on estimated glomerular filtration rate [6 months after medicine use: SMD: -0.56 (95% CI: -1.38, 0.26)], 12 months after medicine use: [SMD: 0.10 (95% CI: -0.05, 0.26)]. Conclusion: SGLT2 inhibitors were not effective in lowering blood pressure, estimated glomerular filtration rate, serum creatinine, and hemoglobin A1c levels, or weight in kidney transplant patients. Although SGLT2 inhibitors were ineffective in improving kidney transplant patients’ renal function, there were no side effects, and the administration of this drug in kidney transplant patients can continue. Further research is required to ensure safety and determine the appropriate dosage and duration of drug use. Registration: The study was compiled according to the PRISMA checklist and its protocol was registered on the PROSPERO (ID: CRD42023407501) and Research Registry (UIN: reviewregistry1666) websites.

Published: August 2023

Los objetivos del presente trabajo de tesis fueron: reportar con ultrasonografía en modo B y Doppler los cambios ováricos y uterinos durante la pubertad canina; describir con ultrasonografía en modo B y Doppler los cambios ováricos y uterinos durante la pubertad felina; comparar las características ultrasonográficas bidimensionales y Doppler de ovarios y útero en gatas pospúberes durante las distintas fases del ciclo estral; determinar el momento de cierre fisiario en los huesos del esqueleto apendicular en caninos de talla pequeña y analizar la relación entre el cierre de los cartílagos fisiarios y la pubertad. Para las evaluaciones ultrasonográficas se utilizaron 8 perras prepúberes y 16 gatas, de las cuales 9 fueron prepúberes y 7 pospúberes. Se realizaron evaluaciones ultrasonográficas en modo B y Doppler color y pulsado de los ovarios y útero durante su desarrollo puberal y en las hembras felinas adultas, durante un ciclo estral anovulatorio. Adicionalmente, se evaluaron mensualmente 12 perros mediante radiografías simples, desde los 3 a los 12 meses de edad. Durante la pubertad canina y felina, se identificaron cambios morfológicos y de flujo sanguíneo en los ovarios y útero a través del uso de ultrasonografía B y Doppler. En ambas especies, se evidenció el aumento del tamaño ovárico y uterino, como así también del número y tamaño de estructuras foliculares hacia el primer celo. Dichos cambios fueron acompañados por aumento en el flujo sanguíneo, evidenciado por una disminución en el IR de las arterias intraováricas y uterinas. En gatas pospúberes, también se documentaron cambios morfológicos y vasculares de los ovarios y útero a lo largo del ciclo estral anovulatorio. Se reportó por primera vez la cronología del cierre fisiario en caninos de talla pequeña mediante radiografías y fue posible determinar la influencia de la pubertad sobre algunas de las fisis evaluadas.

To ensure accurate and consistent fertilizer application, the key component of the fertilizer feeding device, the grooved wheel, was designed and theoretically analyzed, and the number of grooves of the fertilizer wheel was determined to be 9. The effects of grooves inclination angle, grooves length and operating speed on the fertilizer feeding performance were analyzed by single-factor tests, and the appropriate range of factors was determined. The effect of the interaction between groove length and operating speed on the amount of fertilizer discharged from the groove was investigated by a full factorial test, and a quadratic regression was fitted to the test results to establish the regression equations of groove length and operating speed on the average fertilizer application per groove and the coefficient of variation of the average fertilizer application per groove, which can be used to predict the average fertilizer application per groove and the coefficient of variation of the average fertilizer application per groove to solve for groove length and operating speed.

Published: August 2023

As power systems undergo a transformation with increasing inverter-based resources (IBRs), understanding the stability and dynamics of IBR-dominated systems becomes imperative. Though analytical models offer insights into these changes, intellectual property constraints introduce a challenge due to the black-box nature of IBRs, highlighting the importance of frequency-domain-based methods using IBRs’ measured admittance. While simulation environments provide ease in impedance measurement, real-world implementation faces challenges due to the absence of ideal voltage or current sources. This has prompted the use of varied devices, such as power amplifiers and frequency response analyzers, for perturbation generation and injection. Notably, utilizing another measurement inverter as the perturbation source offers a promising approach, despite its limitations such as degrading system stability and prolonging the measurement time. This article introduces an innovative control strategy for the measurement inverter, detailing the effects of abc/dq and dq/abc transformations on the measured admittance. The groundbreaking contributions are the revelations about the admittance contributions of these transformations and the introduction of double phase-locked loops, optimizing both system stability and measurement time.

The aim of this study was to identify morphological and morphometric variations of pulmonary fissures. A sample of 50 adult formalin fixed Sri Lankan cadaveric lungs (24 left and 26 right lungs) were observed with the help of magnifying glass and length measurements of the lung fissures were taken using a measuring tape. Complete oblique fissure was seen in 16 (66.67%) left lungs and 11 (42.3%) right lungs. Incomplete oblique fissure was seen in 8 (33.33%) left lungs and 15 (57.69%) right lungs. There was complete absent of horizontal fissure in 4 (15.38%) right lungs whereas rest of the 22 right lungs indicated incomplete horizontal fissure (84.61%). The mean lengths of the left oblique fissure, right oblique fissure and horizontal fissure were 26.88±5.88cm, 27.31±6.04 cm and 8.31±3.61 cm, respectively. Incomplete fissure was the most common variant of the fissures in the analyzed sample. There was a high prevalence of incomplete horizontal fissure of right lung followed by incomplete right and left oblique fissures. Absence of oblique fissure was not found in either left or right lungs. The mean length of right oblique fissure was slightly greater than the mean length of left oblique fissure. The knowledge lung fissures, indeed help clinicians and radiologists to identify alterations of the disease distribution and to reduce the misinterpretation of radiological modalities as well as to arrive at an accurate diagnosis with plan of management of a patient.

Published: August 2023

Horseshoe kidney (HSK), the most common type of congenital renal fusion anomaly, is characterized by ectopia, malrotation, and altered vascular changes. Horseshoe kidney in this case is atypical because of multiple ureters, arteries, and veins, as well as how they originated and formed. During the routine dissection of 83-year-old male donor who died of respiratory failure, we observed the presence of horseshoe kidney in which the lower lobes of the left and right kidneys were connected by an isthmus below the level of inferior mesenteric artery (IMA). Furthermore, the presence of arterial, venous, and ureteric anomalies was also observed; these were sequentially dissected and are described here.

It is a sudden and severe inflammation of the appendix. The symptoms of acute appendicitis occur suddenly and are usually severe. In severe cases, appendicectomy is often needed. Aim of the study: The aim of this study was to compare between pre-operative and intra-operative findings among patients with acute appendicitis. Methods: This cross-sectional study was conducted in the department of Surgery, North East Medical College Hospital, Sylhet, Bangladesh during the period from July 2008 to June 2009. In total 100 clinically diagnosed cases of acute appendicitis were enrolled in this study as study subjects. Proper written consents were taken from all the participants before data collection. All the pre-operative and intra-operative findings among patients were recorded and analyzed. All data were processed, analyzed and disseminated by using SPSS version 16.0 program as per necessity. Results: In this study, among total 100 cases, clinically acute appendicitis was found in 78% and burst appendix in 22% of cases. Appendix was found retrocaecal in 67%, pelvic in 30% and pracaecal, subcaecal and postileal each comprises 1% of the patients. Finally, we found a significant correlation of pre-operative diagnosis with luminal contents (P<0.0001). Besides this, the findings of this study indicated that, the clinical diagnosis was concordance with intra-diagnosis in 84% of cases and discordant in 16% of cases. Conclusion: In this current study, pre-operative clinical diagnosis was concordance with intra-operative diagnosis in majority of the cases. So, we can conclude that, the surgeon should be careful about the pre-operative assessment of the cases in ........

Stunting in children is associated with motor problems and death, stunted brain development, motor, mental growth, and reduced physical capacity, productivity and economy. Nutrition-based interventions can reduce the incidence of stunting. Local food-based foods that children like can be an alternative to increase the intake of protein and micronutrients needed in children's growth. This study aimed to determine the most preferred formula of rebon flour substitution in mackerel sausage. The research design was experimental with a completely randomized design method. The product consists of F0, F1, F2, F3, F4, and F5. Formulation F0 was a control sausage formulation made from mackerel: rebon flour with a ratio of 100%:0%. F1 was the formula for mackerel rebon sausage with the composition of mackerel: rebon flour (95%:5%), F2 (90%:10%), F3 (85%:15%), F4 (80%:20%) and F5 (75%:25%). The ANOVA test showed that the panelists' preference for each formulation differed significantly (p=0,000). The greater the percentage of rebon flour subsites used in mackerel sausage, the less favorable the aroma, color, taste, and texture. Friedman's test showed that mackerel sausage substituted with 5% dry rebon flour was the most preferred sausage formulation. 100 g of boiled sausage contained 147 kcal of energy, 11,72 g of protein, 20,67 g of carbohydrates, 18 mg of Fe, 3,69 mg of Zn and 217,73 mg of calcium. The energy content of sausages can be increased by serving sausages after frying.

Hypertension is a condition characterized by systolic blood pressure ratings. Blood pressure reflects the resistance generated each time the heart beats and sends blood flow through the arteries, the highest record pressure generated by these contractions is called systolic pressure. The study aimed to determine the relationship between knowledge and attitudes with the incidence of hypertension. Quantitative research design with cross sectional study, with a sample of 76 subjects. The results of the chi square test obtained knowledge p-value=0,038, attitude= 0,003. It can be concluded that there is a relationship between people's attitudes and the incidence of hypertension. Community recommendations further improve counseling programs on hypertension and work with health workers with the community in prioritizing health services so that people prefer and determine a better and correct way of life.
The Choice! The challenges of trying to improve medical students’ satisfaction with their specialty choices
Authors: Davis Melinda , Desy Janeve , Kassam Aliya , Mclaughlin Kevin
Published: August 2023

The authors describe the residency match as a two-step process. The first step, the Choice, is where students use a combination of intuitive and analytic information processing to select the specialty that they believe will provide fulfilment and work-life balance over their entire career. The second step, the Match, uses a “deferred-acceptance” algorithm to optimize pairing of students and their specialty choices. Despite being the rate-limiting step, outcomes of the Choice have typically been eclipsed by the outcomes of the Match. A recently published study found that during their second year of residency training, 1 in 14 physicians reported specialty choice regret, which associates with symptoms of burnout in residents. While the obvious solution is to design interventions that improve the specialty choices of students, this approach faces significant challenges, including the fact that: 1) satisfaction with specialty choice is a difficult-to-define construct; 2) specialty choice regret may be misattributed to a poor choice; and 3) choosing is a more complicated process than matching. The authors end by suggesting that if we hope to improve satisfaction with specialty choice then we should begin by defining this, deciding when to assess it, and then creating assessment tools for which there is validity evidence and that can identify the underlying causes of specialty choice regret.
DROIT AU BUT AVEC L’IA : UNE RÉVOLUTION À BAS BRUIT POUR LE FOOTBALL PROFESSIONNEL
Authors: Paché Gilles
Published: August 2023

Les supporters réunis dans un stade afin de soutenir ardemment leur équipe de football professionnel favorite ignorent très certainement l’influence majeure de l’intelligence artificielle (IA) dans le choix des joueurs, voire dans la tactique de jeu définie par l’entraîneur. On peut parler d’une véritable révolution à bas bruit dans une industrie du divertissement dont on connaît les énormes enjeux financiers, politiques et sociétaux. L’article aborde un aspect singulier de l’usage de l’IA dans l’univers du football professionnel à partir du partenariat conclu en 2023 entre une ligue professionnelle et une start-up de haute technologie : l’élargissement majeur du « vivier » des talents, à savoir l’identification de jeunes footballeurs qui passent à travers les mailles du filet de la détection « traditionnelle », puis leur gestion une fois recrutés par les clubs. Il s’agit incontestablement d’une thématique de première importance, proche de problématiques « ressources humaines », qui ne peut laisser indifférents les chercheuses et chercheurs en sciences du management.

A brief analysis of Article 368 and some important cases around it
Authors: Sahu Rutushree
Published: August 2023

This paper discusses the relationship between the judiciary and the legislature in India. It argues that the judiciary has the power of judicial review, which allows it to strike down laws that it deems to be unconstitutional. This power has been used by the judiciary to balance the power of the legislature and to ensure that the rights of citizens are protected. The paper begins by discussing the history of judicial review in India. It then examines the two landmark cases in which the Supreme Court of India has upheld its power of judicial review: Kesavananda Bharati v. State of Kerala and Minerva Mills v. Union of India. The paper then discusses the implications of judicial review for the relationship between the judiciary and the legislature. The paper argues that judicial review is a necessary check on the power of the legislature. It also argues that judicial review can help to protect the rights of citizens. However, the paper also acknowledges that judicial review can be used to interfere with the democratic process. The paper concludes by arguing that the judiciary and the legislature should work together to ensure that the power of judicial review is used in a responsible way and focuses on the point that the legislature should be transparent about its decision-making process and that it should be accountable to the people.
