The Effect of the Flipped Classroom on the Academic Achievement in Physics and Motivation Among Students of Secondary Stage in Jordan

Learning physics outside the classroom has experienced low consideration in the past, but it has gained popularity in recent times. The current study aimed to explore the effect of using the flipped classroom strategy in teaching physics on academic achievement and motivating secondary school students in Jordan. A total of 84 students from the eleventh grade of secondary education from the Jordanian Ministry of Education participated in the study, divided into two groups, the experimental group (41) and the control group (43). Educational materials and study tools; comprehending scientific flipped classroom strategy designed and charted content, the Physics academic achievement test as well as the Physics motivation scale; were developed and prepared. Study instruments were appropriately statistically pre-checked for validity and reliability. The results revealed that there were statistically significant differences between the experimental group and the control group in favor of the experimental group. The results also showed that there were no statistically significant differences between the mean scores of the experimental group students and the scores of the control group students in the post-application of the motivation scale due to the teaching method. The study recommends further studies on the flipped classroom strategy

Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)

Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic

Urban regeneration process of Eskisehir/Turkey in the context of sustainable development

Bu çalışma, 12-14 Haziran 2010 tarihleri arasında Amman[Ürdün]’da düzenlenen 2. International Conference on Sustainable Architecture and Urban Development (SAUD)’da bildiri olarak sunulmuştur.The aim of the paper is to put stress on the importance and necessity of urban regeneration for sustainable development of cities. The concept of urban regeneration is undertaken as an integrated process for environmental, social and economic development of urban areas. For this aim, urban regeneration process in Eskisehir is explained via examples of implementations undertaken in different parts of the city. Eskisehir is one of the earliest and most industrialized cities in a developing country, Turkey. The urban regeneration examples explored in the scope of this paper are pioneer studies not only for conservation and revitalization of natural, industrial and historical heritage of the city, but also for the country. In spite of being parallel strands of urban policy of many countries, greater emphasis is given to achieving urban regeneration, especially in economical terms, rather than to sustainability. However, it should be considered that all urban regeneration examples contribute to sustainable development through the recycling of derelict land and buildings, reducing demand for peripheral development and facilitating the development of more compact cities (Urban Task Force, 2005). After examining the urban regeneration studies implemented in natural, industrial and historical heritage sites of the city in the context of environmental, social and economic sustainability; the paper discusses the achievements and the deficiencies of the studies in local and regional scales. The authors put stress on the leading role of local government in providing integrated approaches to land management policies and sustainable urban development.Univ Dunde

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
