Implementing Pragmatism And John Deweys Educational Philosophy In Jordanian Public Schools

The teachings and writings of John Dewey, an American philosopher and educator, offer insightful influences on contemporary education, not only in the United States but also worldwide. His philosophy of education, commonly referred to as Pragmatism, focused on learning by doing as an alternative to rote knowledge and strict teaching. The purpose of this study is to investigate the extent to which this philosophical thought is implemented in Jordanian public schools according to Jordanian teachers. Both quantitative and qualitative methods were employed in this study. The findings reveal that Jordanian teachers believe Pragmatism is implemented in Jordan to a moderate degree

L’ impact des conditions de travail en contexte logistique sur la santé des travailleurs : Etude exploratoire de la filière de production des fruits et légumes dans la région du Souss Massa

Les mutations récentes dans le fonctionnement des chaînes logistiques à travers la mise en tension des flux et la recherche de productivité à travers la mise en œuvre des démarches d’amélioration continue exercent un impact négatif sur la santé mentale et physique des travailleurs. Plusieurs chercheurs ont tenté d’évaluer l’effet des conditions de travail dans les métiers de la logistique sur la santé des salariés notamment en ce qui concerne les conducteurs routiers et les opérateurs d’entrepôts et des centres de distribution (Paché & Large, 2016). Pour le cas du Maroc, la littérature sur la santé au travail en contexte logistique est quasi absente. Ainsi, l’objectif de notre article est, d’une part, identifier les facteurs de pénibilité dans le secteur de la logistique et, d’autre part, évaluer leurs effets sur la santé et sécurité au travail (SST). Pour cela, nous adopterons une approche exploratoire, basée sur des entretiens semi-directifs afin d’éclaircir cette problématique

Ocena emisije gasova s efektom staklene bašte lanca snabdevanja kukuruzovine

Within this investigation, different scenarios for supply chains of corn stover intended for biogas production were evaluated in terms of emissions of the greenhouse gasses and their impact to global warming. A primary difference between the scenarios was due to application of different stover collection techniques i.e. forage harvester, baling of big rectangular and round bales. It was found that the supply chain, which includes the application of forage harvester for stover collection is characterized by the highest value of impact, approximately 70 and 85 kg CO2 eq MgDM–1, respectively for the usual and reduced corn stover yield. For the supply chain which includes baling of big rectangular bales, these values are around 62 and 68 kg CO2 eq MgDM–1, and for the baling of round bales, values are 61 and 67 kg CO2 eq MgDM–1. Among the analyzed greenhouse gases emissions, the dominant impact is due to the emissions of carbon dioxide. The reduction of the corn stover yield, caused by extreme drought, is followed by higher GHG emissions, first of all due to longer distances during harvest and transportation.U okviru istraživanja su, za različite scenarije lanca snabdevanja kukuruzovinom namenjene za proizvodnju biogasa, određene vrednosti emisija gasova s efektom staklene bašte i ocenjen njihov uticaj na doprinos globalnom zagrevanju. Osnovna razlika između scenarija proizilazi iz načina ubiranja kukuruzovine i to silažnim kombajnom i formiranjem velikih četvrtastih i valjkastih bala. Ustanovljeno je da se lanac snabdevanja sa primenom silažnog kombajna rezultuje najvišom vrednošću uticaja, koja iznosi 70 i 85 kg CO2 ekv MgSM–1, za visok i nizak prinos kukuruzovine respektivno. Za lanac sa ubiranjem u formi četvrtastih bala, te vrednosti iznose 62 i 68 kg CO2 ekv MgSM–1, a za valjkaste bale 61 i 67 kg CO2 ekv MgSM–1. Od analiziranih gasova s efektom staklene bašte, dominantan uticaj ima ugljen-dioksid. Smanjenje prinosa kukuruzovine, usled suše, nepovoljno se odražava na lanac snabdevanja, pre svega zbog dužine puta pri ubiranju i transportu

Home exposure to Arabian incense (bakhour) and asthma symptoms in children: a community survey in two regions in Oman

<p>Abstract</p> <p>Background</p> <p>Incense burning has been reported to adversely affect respiratory health. The aim of this study was to explore whether exposure to bakhour contributes to the prevalence of asthma and/or triggers its symptoms in Omani children by comparing two Omani regions with different prevalence of asthma.</p> <p>Methods</p> <p>A randomly selected sample of 10 years old schoolchildren were surveyed using an Arabic version of ISAAC Phase II questionnaires with the addition of questions concerning the use and effect of Arabian incense on asthma symptoms. Current asthma was defined as positive response to wheeze in the past 12 months or positive response to "ever had asthma" together with a positive response to exercise wheeze or night cough in the past 12 months. Simple and multivariable logistic regression analyses were performed to estimate the effect of bakhour exposure and other variables on current asthma diagnosis and parents' response to the question: "Does exposure to bakhour affect your child breathing?"</p> <p>Results</p> <p>Of the 2441 surveyed children, 15.4% had current asthma. Bakhour use more than twice a week was three times more likely to affect child breathing compared to no bakhour use (adjusted OR 3.01; 95% CI 2.23–4.08) and this effect was 2.55 times higher in asthmatics (adjusted OR 2.55; 95% CI 1.97–3.31) compared to non-asthmatics. In addition, bakhour caused worsening of wheeze in 38% of the asthmatics, making it the fourth most common trigger factor after dust (49.2%), weather (47.6%) and respiratory tract infections (42.2%). However, there was no significant association between bakhour use and the prevalence of current asthma (adjusted OR 0.87; 95% CI 0.63–1.20).</p> <p>Conclusion</p> <p>Arabian incense burning is a common trigger of wheezing among asthmatic children in Oman. However, it is not associated with the prevalence asthma.</p

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10&nbsp;years; 78.2% included were male with a median age of 37&nbsp;years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p&lt;0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p&lt;0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Genetic mechanisms of critical illness in COVID-19.

Host-mediated lung inflammation is present1, and drives mortality2, in the critical illness caused by coronavirus disease 2019 (COVID-19). Host genetic variants associated with critical illness may identify mechanistic targets for therapeutic development3. Here we report the results of the GenOMICC (Genetics Of Mortality In Critical Care) genome-wide association study in 2,244 critically ill patients with COVID-19 from 208 UK intensive care units. We have identified and replicated the following new genome-wide significant associations: on chromosome 12q24.13 (rs10735079, P = 1.65 × 10-8) in a gene cluster that encodes antiviral restriction enzyme activators (OAS1, OAS2 and OAS3); on chromosome 19p13.2 (rs74956615, P = 2.3 × 10-8) near the gene that encodes tyrosine kinase 2 (TYK2); on chromosome 19p13.3 (rs2109069, P = 3.98 ×  10-12) within the gene that encodes dipeptidyl peptidase 9 (DPP9); and on chromosome 21q22.1 (rs2236757, P = 4.99 × 10-8) in the interferon receptor gene IFNAR2. We identified potential targets for repurposing of licensed medications: using Mendelian randomization, we found evidence that low expression of IFNAR2, or high expression of TYK2, are associated with life-threatening disease; and transcriptome-wide association in lung tissue revealed that high expression of the monocyte-macrophage chemotactic receptor CCR2 is associated with severe COVID-19. Our results identify robust genetic signals relating to key host antiviral defence mechanisms and mediators of inflammatory organ damage in COVID-19. Both mechanisms may be amenable to targeted treatment with existing drugs. However, large-scale randomized clinical trials will be essential before any change to clinical practice

Whole-genome sequencing reveals host factors underlying critical COVID-19

Critical COVID-19 is caused by immune-mediated inflammatory lung injury. Host genetic variation influences the development of illness requiring critical care1 or hospitalization2–4 after infection with SARS-CoV-2. The GenOMICC (Genetics of Mortality in Critical Care) study enables the comparison of genomes from individuals who are critically ill with those of population controls to find underlying disease mechanisms. Here we use whole-genome sequencing in 7,491 critically ill individuals compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical COVID-19. We identify 16 new independent associations, including variants within genes that are involved in interferon signalling (IL10RB and PLSCR1), leucocyte differentiation (BCL11A) and blood-type antigen secretor status (FUT2). Using transcriptome-wide association and colocalization to infer the effect of gene expression on disease severity, we find evidence that implicates multiple genes—including reduced expression of a membrane flippase (ATP11A), and increased expression of a mucin (MUC1)—in critical disease. Mendelian randomization provides evidence in support of causal roles for myeloid cell adhesion molecules (SELE, ICAM5 and CD209) and the coagulation factor F8, all of which are potentially druggable targets. Our results are broadly consistent with a multi-component model of COVID-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication; or an enhanced tendency towards pulmonary inflammation and intravascular coagulation. We show that comparison between cases of critical illness and population controls is highly efficient for the detection of therapeutically relevant mechanisms of disease
