The Effectiveness of Star Strategy Learning on Gifted Students Mathematical Creative Thinking Ability

The purpose of this research is to investigate the mathematics creative thinking skills of gifted students in the International Private School before, during, and after receiving instruction using the STAR method. An analysis of behaviour analysis (ABA) was used as the study approach for the exploration of a certain subject. The sample of the study was selected from International private school in Al-Ain, UAE during the academic year 2020-2021. The investigation focused on two pupils who were both considered to have impressive levels of academic ability. An exercise in description was used as a component of the investigation. According to the findings of this research, subject G1 exhibited a higher ability for mathematically innovative thinking than subject G2 did in baseline condition 2 (A2), with subject G1 attaining 93.33 percent and subject G2 achieving 90 percent. Throughout the whole of this experiment, this was consistently the case for both of the individuals. Subject G1 had a higher percentage of creative thinking ability than subject G2 (83.3% vs. 81.5%), despite the fact that in baseline condition 1 (A1), both individuals creative thinking abilities were at their lowest possible level. Subject G1 had a score of 88.75% in the intervention condition, whereas subject G2 had a score of 86.25% in the intervention condition. This research came to the conclusion that the use of the STAR learning technique, which consists of the phases Search, Translate, Answer, and Review, is beneficial on mathematical creative thinking abilities as measured by Problem Sensitivity, Fluency, Flexibility, Originality, and elaboration

Conséquence d'une coupe rase ou d'une éclaircie sur la richesse spécifique et le mode de dissémination des espèces végétales dans des forêts de pin d'Alep du Var (Sud de la France)

Les conséquences de différents types de coupe sur la diversité végétale et le suivi des variations observées dans le temps ont été analysées par l'intermédiaire de la richesse spécifique et d'une approche plus fonctionnelle sur des forêts de pin d'Alep du Centre Var (variations du nombre d'espèces et des modes de dissémination des espèces végétales). Les résultats indiquent que les effets de ces différents types de coupe sont très marqués les trois premières années après la coupe, puis ils s'estompent jusqu'à pratiquement disparaître au bout de dix ans environ

Does true Gleason pattern 3 merit its cancer descriptor?

Nearly five decades following its conception, the Gleason grading system remains a cornerstone in the prognostication and management of patients with prostate cancer. In the past few years, a debate has been growing whether Gleason score 3 + 3 = 6 prostate cancer is a clinically significant disease. Clinical, molecular and genetic research is addressing the question whether well characterized Gleason score 3 + 3 = 6 disease has the ability to affect the morbidity and quality of life of an individual in whom it is diagnosed. The consequences of treatment of Gleason score 3 + 3 = 6 disease are considerable; few men get through their treatments without sustaining some harm. Further modification of the classification of prostate cancer and dropping the label cancer for Gleason score 3 + 3 = 6 disease might be warranted

Twelve-month observational study of children with cancer in 41 countries during the COVID-19 pandemic

Introduction Childhood cancer is a leading cause of death. It is unclear whether the COVID-19 pandemic has impacted childhood cancer mortality. In this study, we aimed to establish all-cause mortality rates for childhood cancers during the COVID-19 pandemic and determine the factors associated with mortality. Methods Prospective cohort study in 109 institutions in 41 countries. Inclusion criteria: children <18 years who were newly diagnosed with or undergoing active treatment for acute lymphoblastic leukaemia, non-Hodgkin's lymphoma, Hodgkin lymphoma, retinoblastoma, Wilms tumour, glioma, osteosarcoma, Ewing sarcoma, rhabdomyosarcoma, medulloblastoma and neuroblastoma. Of 2327 cases, 2118 patients were included in the study. The primary outcome measure was all-cause mortality at 30 days, 90 days and 12 months. Results All-cause mortality was 3.4% (n=71/2084) at 30-day follow-up, 5.7% (n=113/1969) at 90-day follow-up and 13.0% (n=206/1581) at 12-month follow-up. The median time from diagnosis to multidisciplinary team (MDT) plan was longest in low-income countries (7 days, IQR 3-11). Multivariable analysis revealed several factors associated with 12-month mortality, including low-income (OR 6.99 (95% CI 2.49 to 19.68); p<0.001), lower middle income (OR 3.32 (95% CI 1.96 to 5.61); p<0.001) and upper middle income (OR 3.49 (95% CI 2.02 to 6.03); p<0.001) country status and chemotherapy (OR 0.55 (95% CI 0.36 to 0.86); p=0.008) and immunotherapy (OR 0.27 (95% CI 0.08 to 0.91); p=0.035) within 30 days from MDT plan. Multivariable analysis revealed laboratory-confirmed SARS-CoV-2 infection (OR 5.33 (95% CI 1.19 to 23.84); p=0.029) was associated with 30-day mortality. Conclusions Children with cancer are more likely to die within 30 days if infected with SARS-CoV-2. However, timely treatment reduced odds of death. This report provides crucial information to balance the benefits of providing anticancer therapy against the risks of SARS-CoV-2 infection in children with cancer

Is there an economic case for legume-cereal rotation? A Case of Faba-beans in the Moroccan Wheat Based Production Systems

While the impacts of legume-cereal rotations on soil health are well documented, the literature on their economic benefits, especially in dry areas is scanty. By applying the propensity score matching and endogenous switching regression methods to a nationally representative sample of 1,230 farm households from Morocco, this paper provided empirical evidence that the individual and combined adoption of improved varieties of faba-beans and legume-wheat rotations lead to higher yields, farm income and household consumption. Considering a two-year period, the simultaneous adoption of both faba-bean-wheat rotation and improved faba-bean varieties led to $875/ha (136%%) higher net returns relative to wheat mono-cropping. In the face of these very high benefits, high risk of losing faba-bean crops due to pests, diseases or drought explain the low adoption of rotation and improved varieties which are at 26% and 16% respectively. For reaping both the economic and environmental benefits of faba-beans, Morocco and other similar countries in the dry areas will need to invest on the development of varieties with better pest and diseases resistance, introduce crop insurance and different incentive systems, and create better access to extension and certified seed delivery services that induce wider adoption of improved varieties and legume-cereal rotations.
