Teacher performance characteristics and pupil outcomes within science classrooms in Kuwaiti high schools
No one can deny the wealth of information that has been gained in the last seventy years or so, in relation to what happens in classrooms and about relationships between teachers' behaviours and other variables related to the quality of teaching. The main purpose of this study was to: 1) see how science has been introduced in some Kuwaiti high schools; 2) examine the effects the adopted methods of teaching may have had on Kuwaiti pupils' intellectual outcomes; 3) examine the effects the sex of pupils /teachers may have had on the intellectual attainments of the observed fourth grade high school pupils; 4) assess how pupils perceived their science teachers' behaviours and to compare these perceptions with those of science supervisors, in Kuwait, of these same teachers; 5) examine the effects the sex of pupils/teachers may have had on the perception of pupils to the characteristics of their science teachers6) locate variables related to both the behaviours of the observed science teachers, in their classrooms, and the teacher-pupil classroom interaction variables that affected the achievement of science pupils. Thus this present research is the first comprehensive observational study undertaken of science teaching in Kuwaiti high schools
Influence of Teaching Style on Studentsâ Engagement, Curiosity and Exploration in the Classroom
Inside classroom teacher student interaction carries immense significance as it appears to contribute to student learning in different ways. The teachersâ interaction has a stronger association with studentsâ engagement and exploration in terms of learning in classroom through their coaching style. The present study therefore aims to explore perceived teaching style (autonomous-supportive and/or controlling) and its correlation with studentsâ engagement, curiosity and exploration in cross-sectional sample of School and University students (N= 402). Perceived parental autonomy support scale (adopted version for teachers), Students Engagement Instrument and Curiosity Exploration Inventory-II were administered. The result shows that students simultaneously perceived both teaching styles i.e., Autonomous-supportive and Controlling, in classroom however there was a significant difference between score of school students where they find their teachers to be more supportive and controlling as compared to university students. Furthermore, there is a moderate correlation between perceived autonomy support teaching style with studentsâ engagement as well as curiosity and exploration. The results offers an understanding of studentsâ belief and perceptions about their interaction with teachers that can help in building studentsâ curiosity and motivation to engage learn in the classroom
Mediation Effect of Service Quality on the Relationship of Healthcare Service Innovation and Outpatient Experience
Healthcare organizations play an important role in people's well-being all over the world; good healthcare facilities are extremely beneficial in combating many diseases worldwide. Innovation is one of the most important factors influencing service quality in healthcare organizations worldwide, particularly in the UAE. The pandemic, changing human needs and globalization have made organizations more aware of the importance of improving patients' experiences through improved service quality and innovative services, which has become a winning strategy and provides organizations with a comparative advantage over others through customer confidence building. This research assessed mediating effect of service quality on health services innovation and outpatient experience. The model was developed with the help of SmartPLS software package and the data was gathered through questionnaire survey. Analysis of 397 questionnaire forms were used to analyze direct relations between service quality and service innovation with out-patient experience as well as indirect effect of service innovation on out-patient experience through service quality. The developed model was confirmed through convergent validity and discirminant validity. The R-square reveals that service innovation accounted for approximately 47% of the variation in service quality. While service innovation and service quality explained approximately 80% of the change in outpatient experience. This means that a unit change in both service innovation and service quality improves the outpatient experience by 80%
Measurement the Producting Efficiency and Marketing Efficiency of Okra Crop (Covered) in Baghdad Governorate for the Season 2022
Purpose: The aim of the research is to estimate the production and marketing efficiency of okra under the protected agriculture system and to identify the most important production and marketing problems.
Theoretical Framework: The least squares method OLS was used to estimate the parameters of the short-term
cost function using the statistical program SSPS, and the short-term cubic cost function was adopted.
Design/Methodology: Data were collected through a questionnaire form for a random sample of 62 farmers of the covered okra crop in Baghdad Governorate (Mahmoudiya District) for the season 2022-2023, to measure the production and marketing efficiency of okra under the protected agriculture system.
Findings: There is economic efficiency in the production of okra, the ratio of return to costs is greater than one, while the production costs function indicated that the crop does not achieve the required level of efficiency, as the optimal volume of production was about 12.22 tons. the average production volume of the selected sample was about 4.3 tons, and the estimated results also indicated that the total cost about 23350570 ID, and the marketing efficiency of the crop about 85%.
Practical and Social Effects: The study benefits okra farmers through knowledge of the optimal use of available resources, i.e. the production of the largest amount of goods and services using the elements of production available, exploiting the resources available to it to produce goods and services that specialize in its production, farmers achieve marketing efficiency through maximizing the ratio between outputs and inputs.
Value or Origin: The agricultural sector in Iraq is of great importance among other economic sectors. Meanwhile, it faces many challenges, including population increase, limited land and water resources, inefficient use of available resources, and lack of the seasonality of agricultural production coincides with the periods required for consumption, which makes the transition to protected agriculture necessary to increase agricultural production as one of the means of agricultural intensification to increase agricultural production to meet the increased demand for crops. Therefore., studying marketing efficiency is one of the important studies, as it is the main factor for continuing to deal in the production and of any crop or not
Histopathological Effects on Testis of Adult Male Carp, Cyprinus carpio carpio, Following Exposure to Graded Concentrations of Water-Borne Bisphenol A
Purpose: To evaluate the estrogenic effect of Bisphenol A (BPA), an endocrine disruptor on the histological features in carp testisMethods: Adult male fish, koi carp, Cyprinus carpio carpio, were exposed to three graded concentrations of BPA (10, 100 and 1000 ÎŒg/L) for a period of 21 days. A single dose of 17-ÎČ estradiol (1 ng/L) was used as positive control. The end points assessed at the end of the exposure period were condition factor, hepatosomatic index (HSI), gonadosomatic index (GSI), histopathological changes in the testis and lobular diameter.Results: BPA caused a significant decrease in gonadosomatic index (GSI) of the fish at the median concentration of 100 ÎŒg/L. The major alterations observed in the gonad structure were a significant decrease (p †0.001) in the lobular diameter (65.1 ± 12.2 ÎŒm) compared with control (211.7 ± 36.60 ÎŒm) and complete loss in lobular structure with degenerating spermatozoa in some carps. The histopathological effects also include delayed sperm maturation and impaired spermatogenesis.Conclusion: The findings clearly show marked adverse histopathological effects of gonads of adult carps when exposed to BPA.Keywords: Fish, Carp testis, Endocrine disruptors, Bisphenol A, Histopathology, Gonadosomatic index, Sperm maturation, Spermatogenesi
Computational approaches for the design of novel anticancer compounds based on pyrazolo[3,4-d]pyrimidine derivatives as trap1 inhibitor
In the present in-silico study, various computational techniques were applied to determine
potent compounds against TRAP1 kinase. The pharmacophore hypothesis DHHRR_1 consists of
important features required for activity. The 3D QSAR study showed a statistically significant model
with R2 = 0.96 and Q2 = 0.57. Leave one out (LOO) cross-validation (R2 CV = 0.58) was used to
validate the QSAR model. The molecular docking study showed maximum XP docking scores
(â11.265, â10.532, â10.422, â10.827, â10.753 kcal/mol) for potent pyrazole analogs (42, 46, 49, 56,
43), respectively, with significant interactions with amino acid residues (ASP 594, CYS 532, PHE 583,
SER 536) against TRAP1 kinase receptors (PDB ID: 5Y3N). Furthermore, the docking results were
validated using the 100 ns MD simulations performed for the selected five docked complexes. The
selected inhibitors showed relatively higher binding affinities than the TRAP1 inhibitor molecules
present in the literature. The ZINC database was used for a virtual screening study that screened
ZINC05297837, ZINC05434822, and ZINC72286418, which showed similar binding interactions to
those shown by potent ligands. Absorption, distribution, metabolism, and excretion (ADME) analysis
showed noticeable results. The results of the study may be helpful for the further development of
potent TRAP1 inhibitors

An Insight into the Structural Requirements and Pharmacophore Identification of Carbonic Anhydrase Inhibitors to Combat Oxidative Stress at High Altitudes: An In-Silico Approach
Carbonic anhydrases (CA) inhibitory action could be linked to the treatment of a number of ailments, including cancer, osteoporosis, glaucoma, and several neurological problems. For the development of effective CA inhibitors, a variety of heterocyclic rings have been investigated. Furthermore, at high altitudes, oxygen pressure drops, resulting in the formation of reactive oxygen and nitrogen species, and CA inhibitors having role in combating this oxidative stress. Acetazolamide contains thiadiazole ring, which has aroused researchers’ interest because of its CA inhibitory action. In the present study, we used a number of drug design tools, such as pharmacophore modeling, 3D QSAR, docking, and virtual screening on twenty-seven 1,3,4-thiadiazole derivatives that have been described as potential CA inhibitors in the literature. An atom-based 3D-QSAR analysis was carried out to determine the contribution of individual atoms to model generation, while a pharmacophore mapping investigation was carried out to find the common unique pharmacophoric properties required for biological activity. The coefficient of determination for both the training and test sets were statistically significant in the generated model. The best QSAR model was chosen based on the values of R2 (0.8757) and Q2 (0.7888). A molecular docking study was also conducted against the most potent analogue 4m, which has the highest SP docking score (−5.217) (PDB ID: 6g3v). The virtual screening revealed a number of promising compounds. The screened compound ZINC77699643 interacted with the amino acid residues, Pro201 and Thr199, in the virtual screening study (PDB ID: 6g3v). These interactions demonstrated the significance of the CA inhibitory activity of the compound. Furthermore, ADME study revealed useful information regarding compound’s drug-like properties. Therefore, the findings of the present investigation could aid in the development of more potent CA inhibitors, which could benefit the treatment of oxidative stress at high altitudes
Influence of Teaching Style on Studentsâ Engagement, Curiosity and Exploration in the Classroom
Interaction between teachers and students carries immense significance inside classrooms as it contributes to studentsâ learning. The present study aims to explore perceived teaching style (autonomous-supportive and/or controlling) and its correlation with studentsâ engagement, curiosity and exploration in crosssectional sample of school and university students (N= 402). Three questionnaires were used: Perceived Parental Autonomy Support Scale P-PASS (Mageau, et al., 2015); Student Engagement Instrument (Appleton, Christenson, Kim, & Reschly, 2006); and Curiosity and Exploration Inventory (Kashdan, et al., 2009). The results showed that students simultaneously perceived both teaching styles, that is, Autonomous-supportive and Controlling. However, a significant difference was observed between the score of school students where they found their teachers to be more supportive (t (402)=3.942) and controlling (t (402)=4.774) as compared to university students. Furthermore, there was moderate correlation between perceived autonomy support teaching style with studentsâ engagement (r=.463) as well as curiosity and exploration (r=.318). The results offer an understanding of studentsâ perceptions of teaching style contributing to studentsâ curiosity and motivation to engage in classroom
