L’impact De La Formation, Selon Les Normes Qualite, Sur L’implication Du Personnel Sous Contrats Flexibles : Resultats D’une Etude Empirique
This paper introduces the raising interests of certified automotive companies of Tangier-Tétouan region on quantitative flexibilization strategies, via atypical contracts. Therefore, the involvement paradox remains significant through contracts’ flexibility. Thus, the present study aims to analyze the training practices impact according to quality standards on stuff involvement under integration contract. On the methodological standpoint, we have combined between an exploratory qualitative approach and a confirmatory quantitative approach, on the basis of a sample of 170 operators under integration contracts in Moroccan automotive industry. The results show that employees ‘training influences positively on their level of emotional involvement
A Stochastic Capital-Labour Model with Logistic Growth Function
We propose and study a stochastic capital-labour model with logistic growth
function. First, we show that the model has a unique positive global solution.
Then, using the Lyapunov analysis method, we obtain conditions for the
extinction of the total labour force. Furthermore, we also prove sufficient
conditions for their persistence in mean. Finally, we illustrate our
theoretical results through numerical simulations.Comment: This is a preprint whose final form is published by Springer Nature

Benchmarking di-Higgs production in various extended Higgs sector models
We present a comprehensive study on Higgs pair production in various archetypical extended Higgs sectors such as the real and the complex 2-Higgs-Doublet Model, the 2-Higgs-Doublet Model augmented by a real singlet field and the Next-to-Minimal Supersymmetric extension of the Standard Model. We take into account all relevant theoretical and experimental constraints, in particular the experimental limits on non-resonant and resonant Higgs pair production. We present the allowed cross sections for Standard Model (SM)-like Higgs pair production and the ranges of the SM-like Yukawa and trilinear Higgs self-coupling that are still compatible with the applied constraints. Furthermore, we give results for the pair production of a SM-like with a non-SM-like Higgs boson and for the production of a pair of non-SM-like Higgs bosons. We find that di-Higgs production in the models under investigation can exceed the SM rate substantially, not only in the non-resonance region but also due to resonant enhancement. We give several benchmarks with interesting features such as large cross sections, the possibility to test CP violation, Higgs-to-Higgs cascade decays or di-Higgs production beating single Higgs production. In all of our benchmark points, the next-to-leading order QCD corrections are included in the large top-mass limit. For these points, we found that, depending on the model and the Higgs pair final state, the corrections increase the leading order cross section by a factor of 1.79 to 2.24. We also discuss the relation between the description of Higgs pair production in an effective field theory approach and in the specific models investigated here
La diversidad oculta en las identificaciones basadas en la morfología de especies invasoras de amplia distribución: El caso de la bien conocida hidromedusa Craspedacusta sowerbii Lankester 1880
A relatively scarce number of morphological features available for delimiting closely related species and an increasingly worrisome scenario on Global Climate Change causing the rapid dispersion of invasive alien species can lead to the rapid spread of reports of a given species around the world. Craspedacusta sowerbii Lankester, 1880 is considered the most widespread freshwater jellyfish species and has been reported in numerous locations on all continents except Antarctica. Recently, a few medusae attributed to C. sowerbii were collected from a water reservoir (Bin El Ouidan) in Morocco, this being the first confirmed record of the species from North Africa. The morphology of these newly collected specimens agrees well with previous descriptions, but mitochondrial (Cox1 and 16S) and nuclear ITS (ITS1–5,8S–ITS2) molecular data lead to a discussion of a more complex general view concerning the number of species, synonyms and nomenclatural problems hidden behind the reports of Craspedacusta sowerbii

The Clinical Implementation of CYP2C19 Genotyping in Patients with an Acute Coronary Syndrome:Insights From the FORCE-ACS Registry
BACKGROUND: Guidelines recommend prasugrel or ticagrelor for acute coronary syndrome (ACS) patients. However, these P2Y12 inhibitors increase bleeding risk compared to clopidogrel. Although genotype-guided P2Y12-inhibitor selection has been shown to reduce bleeding risk, data on its clinical implementation is lacking. METHODS: The study included ACS patients receiving genotype-guided antiplatelet therapy, utilising either a point-of-care (POC) device or laboratory-based testing. We aimed to collect qualitative and quantitative data on genotyping, eligibility for de-escalation, physician adherence to genotype results, time to de-escalation and cost reduction. RESULTS: Of the 1,530 patients included in the ACS registry from 2021 to 2023, 738 ACS patients treated with ticagrelor received a CYP2C19 genotype test. The median turnover time of genotyping was 6.3 hours (interquartile range [IQR], 3.2-16.7), with 82.3% of the genotyping results known within 24 hours after admission. POC genotyping exhibited significantly shorter turnaround times compared to laboratory-based testing (with respective medians of 5.7 vs 47.8 hours; P < .001). Of the genotyped patients, 81.7% were eligible for de-escalation which was carried out within 24 hours in 70.9% and within 48 h in 93.0%. The time to de-escalation was significantly shorter using POC (25.4 hours) compared to laboratory-based testing (58.9 hours; P < .001). Implementing this strategy led to a reduction of €211,150.50 in medication costs. CONCLUSIONS: CYP2C19 genotype-guided-de-escalation in an all-comers ACS population is feasible. POC genotyping leads to shorter turnaround times and quicker de-escalation. Time to de-escalation from ticagrelor to clopidogrel in noncarriers was short, with high physician adherence to genotype results.</p
Evolution of pastoral livestock farming on arid rangelands in the last 15 years
Livestock farming in arid rangelands constitute a key component in the agricultural sector, particularly in developing countries. Farms have rapidly changed in recent decades, which has resulted in the modification of their structure, management and economic performance. Nowadays, livestock production in arid rangelands is threatened by climate change, coupled with the impact of complex interactions among social, economic and political factors. The present study analyses the main changes that have occurred on farms in the arid rangelands of south Tunisia from 2004 to 2019 and discusses the factors that explain the geographical patterns of such changes. Data were collected through face-to-face questionnaires with 73 farmers in two years (2004 and 2019). Information included farm structure and management, resources use and economic performance. Multivariate statistical methods analysed the differences in farms typologies between dates and the different pathways of change. Results showed that most farms increased herd size and cereal area for feeding the sheep, and reduced the time spent in rangelands. These changes could be partly explained as a response to decreasing gross margins per livestock unit and the deployment of policies fostering the use of agriculture-based feed resources. Despite these general trends, the variability among pathways of change was wide. Few farms kept using rangelands by focusing on sheep or camel production. Small sheep farms intensified the use of off-farm feeds in the north of the study area, where ecological conditions favoured agriculture. Feed supplementation allowed herd size and animal production to increase, with a substantial risk of susceptibility to market fluctuations. The economic results showed that camel farming combined with small ruminant species can lead to a similar profitability to, or even higher than, large farms that focus solely on sheep and rely on feed supplementation. We conclude that the current situation of livestock farming in arid rangelands remains fragile and their long-term viability is uncertain.Publishe
Bleeding disorders in the tribe: result of consanguineous in breeding
<p>Abstract</p> <p>Objective</p> <p>To determine the frequency and clinical features of bleeding disorders in the tribe as a result of consanguineous marriages.</p> <p>Design</p> <p>Cross Sectional Study</p> <p>Introduction</p> <p>Countries in which consanguinity is a normal practice, these rare autosomal recessive disorders run in close families and tribes. Here we describe a family, living in village Ali Murad Chandio, District Badin, labeled as haemophilia.</p> <p>Patients & Methods</p> <p>Our team visited the village & developed the pedigree of the whole extended family, up to seven generations. Performa was filled by incorporating patients, family history of bleeding, signs & symptoms, and bleeding from any site. From them 144 individuals were screened with CBC, bleeding time, platelet aggregation studies & RiCoF. While for PT, APTT, VWF assay and Factor VIII assay, samples were kept frozen at -70 degrees C until tested.</p> <p>Results</p> <p>The family tree of the seven generations comprises of 533 individuals, 63 subjects died over a period of 20 years and 470 were alive. Out of all those 144 subjects were selected on the basis of the bleeding history. Among them 98(68.1%) were diagnosed to have a bleeding disorder; 44.9% patients were male and 55.1% patients were female. Median age of all the patients was 20.81, range (4 months- 80 yrs). The results of bleeding have shown that majority had gum bleeding, epistaxis and menorrhagia. Most common bleeding disorder was Von Willebrand disease and Platelet functional disorders.</p> <p>Conclusion</p> <p>Consanguineous marriages keep all the beneficial and adversely affecting recessive genes within the family; in homozygous states. These genes express themselves and result in life threatening diseases. Awareness, education & genetic counseling will be needed to prevent the spread of such common occurrence of these bleeding disorders in the community.</p
