Status of Vitamin D Receptor Gene Polymorphism and 25-Hydroxy Vitamin D Deficiency with Essential Hypertension

Essential hypertension (EH) is a multifactorial and complex disease with high rate of incidence and associated co-morbidities. Previous studies do not provide unanimous results for the risk of hypertension and association with Fok I genotype frequency and serum vitamin D levels. Hence, this study was undertaken to determine the status of Fok I vitamin D receptor (VDR) gene polymorphism along with vitamin D levels and blood pressure in patients with EH. Four hundred (200 controls and 200 cases of essential hypertension) participants from general Indian population were enrolled in this study. Peripheral blood samples were collected for genotyping Fok I-VDR gene polymorphism using PCR–RFLP method whereas 25-OH vitamin D levels in serum were quantified using high performance liquid chromatography (HPLC). Significantly reduced 25-OH vitamin D levels were observed in patients with EH (24.04 ± 8.62 vs 50.46 ± 15.46) compared to control subjects (p = 0.0001). Homozygous recessive genotype ‘ff’ frequency was increased by 8.06 fold (CI: 3.71–17.47, p = 0.0001) in patients with EH compared to dominant ‘FF’ genotype frequency. In conclusion, recessive ‘ff’ genotype frequency correlates with reduced serum vitamin D levels and results in significantly increased systolic and diastolic blood pressures leading to predisposition of EH.     

Curriculum reform in a global context: a study of teachers in Jordan

The gap between the educational achievements of the comparatively wealthy and those living in poverty is widening world‐wide, with the associated threat to social cohesion. Twenty‐five years of curriculum reform has largely failed in its objective of providing quality, basic education for all. Arguing that successful innovation requires the participation of willing teachers, and associating this idea with the claim that schools are important for social cohesion, this study surveyed 500 Jordanian elementary teachers about their involvement in a programme of curriculum change and their desire to participate. Twelve key informants were interviewed. The reform has raised the qualifications of teachers and increased male teacher numbers but has neither raised overall standards nor improved truancy rates. Tight central control has failed to engage teachers’ allegiance to the changes. Officials blamed failures on schools; head teachers blamed parents, and teachers criticized a policy that left them mediating a curriculum that lacked relevance and failed to engage pupils.     

The effects of scientific representations on primary students’ development of scientific discourse and conceptual understandings during cooperative contemporary inquiry-science

Teaching students to use and interpret representations in science is critically important if they are to become scientifically literate and learn how to communicate their understandings and learning in science. This study involved 248 students (119 boys and 129 girls) from 26 grade 6 teachers’ classes in nine primary schools in Brisbane, Australia. Teachers were randomly allocated by school to one of three conditions: the contemporary science + representations condition (Experimental^a), the contemporary condition (Experimental^b), or the comparison condition as they participated in an eight-week inquiry-science unit on Natural Disasters. Data on students’ discourse were collected at two time points during the implementation of the unit and data on the concept maps were collected pre- and post-intervention while data on the reasoning and problem-solving (RP-S) task were collected following the intervention. The results show that when students participate in an inquiry-based science unit that is augmented with a variety of multimedia resources presenting a range of current contemporary events (Experimental^a and Experimental^b conditions), they demonstrate significantly more social language and basic scientific language and marked increases in moderate scientific language than their peers in the comparison condition. Interestingly, although there were no significant differences on the Personal Concept Map scores between the conditions at Times 1 and 2, the students’ scores in all conditions improved decidedly across time. It appears that as the children had more time to engage with the material, participate in cooperative peer discussions, and receive encouragement from their teachers to provide elaborated feedback to each other, their conceptual understandings of earthquakes were enhanced. However, although the children in the experimental conditions demonstrated significantly more social and scientific language than their peers in the comparison condition, these oral language skills did not transfer to the RP-S task, possibly because they may not have had enough time to consolidate their application in a novel context where they had to work independently.     

Use of on-line databases by faculty members and research scholars of Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), New Delhi (India): A survey

The study is focused on finding out the level of use of on-line databases by faculty members and research scholars of the Jawaharlal Nehru University (JNU) and Jamia Millia Islamia (JMI), Delhi (India). Both are Central Universities and are funded by the University Grants Commission (UGC). A well-structured questionnaire was administered to faculty members and research scholars of the JNU and JMI to collect data regarding the use of on-line database. The survey reveals that all of the faculty members and research scholars are aware of the availability of on-line databases and largely use them for reference purposes in their research work and studies. The degree of usefulness and utilization of on-line databases is high among the universities' faculty members and research scholars. The survey further reveals that the respondents from both universities are aware of the search options for accessing on-line databases. It is also found that a large number of respondents of JNU and JMI are using field searching and Boolean operators to access information from on-line databases.     

Enhancing employability through industrial training in the Malaysian context

This study discusses the industrial training programme at the University of Malaya in Malaysia, specifically the issues that need to be addressed in order to enhance the employability skills of graduates. Findings from the feedback obtained from trainees and organizations in the 2008/2009 academic session were examined in terms of the extent to which trainees felt they were prepared for their training, and the extent to which the tasks given to them during their training were appropriate. Further, trainees’ self-rating of particular skills and industry’s rating of the trainees were also examined. The feedback is discussed in the context of the need to equip graduates with employability skills, an issue facing Higher Education Providers worldwide. The findings indicate that most of the students were prepared to face the world of work. However, there were several issues which needed attention. These included the need to address the possible mismatch between the tasks assigned to trainees and their areas of study, and the need to enhance English language competency and particular soft skills throughout their degree programme. Continuous input from industry is also necessary to ensure that the training benefits all parties and contributes to the employability skills of trainees.     

A quantitative assessment of classroom teaching and learning in engineering education

All stakeholders are aware of the importance of measuring performance in higher education at the university/college level. Generally the performance indicators used for this purpose have focused on graduation rates and/or final examination scores, rather than the performance-enabling processes. Further, the most commonly used method for knowledge transfer is the traditional classroom teaching, which should be tracked/monitored continuously during its delivery process. It can help in the detection and correction of existing and impending problems, if any, in the teaching and learning processes. Further, the students’ attitude towards learning, that is, their readiness/willingness and interest should also be taken into consideration while measuring the performance of classroom teaching.

In the present paper, the model for measuring classroom performance illustrated by Grygoryev and Karapertrovic (2005) Grygoryev, K. and Karapetrovic, S. 2005. Tracking classroom teaching and learning: an SPC application. Quality engineering, 17: 405–418. [Taylor & Francis Online] [Google Scholar] is used to measure the performance of under-graduate Engineering students in two BTech. (Mechanical) courses, namely, fluid mechaincs (FM) and experimental methods and analysis (EMA). Classroom assessment techniques (CATs) along with the statistical process control (SPC) have been used to analyse the learning performance. Further, the data for student's readiness and interest factors are collected and their positive influences on knowledge gain are established.     

Anatomy education environment measurement inventory: A valid tool to measure the anatomy learning environment

Students' perceptions of the education environment influence their learning. Ever since the major medical curriculum reform, anatomy education has undergone several changes in terms of its curriculum, teaching modalities, learning resources, and assessment methods. By measuring students' perceptions concerning anatomy education environment, valuable information can be obtained to facilitate improvements in teaching and learning. Hence, it is important to use a valid inventory that specifically measures attributes of the anatomy education environment. In this study, a new 11‐factor, 132‐items Anatomy Education Environment Measurement Inventory (AEEMI) was developed using Delphi technique and was validated in a Malaysian public medical school. The inventory was found to have satisfactory content evidence (scale‐level content validity index [total] = 0.646); good response process evidence (scale‐level face validity index [total] = 0.867); and acceptable to high internal consistency, with the Raykov composite reliability estimates of the six factors are in the range of 0.604–0.876. The best fit model of the AEEMI is achieved with six domains and 25 items (X² = 415.67, P < 0.001, ChiSq/df = 1.63, RMSEA = 0.045, GFI = 0.905, CFI = 0.937, NFI = 0.854, TLI = 0.926). Hence, AEEMI was proven to have good psychometric properties, and thus could be used to measure the anatomy education environment in Malaysia. A concerted collaboration should be initiated toward developing a valid universal tool that, using the methods outlined in this study, measures the anatomy education environment across different institutions and countries.

Implementation of co-teaching approach in an inclusive classroom: overview of the challenges,readiness, and role of special education teacher

The objective of this study was to determine the relationship aspect of the challenge, readiness, and the role of special education teacher (SET) in implementing common approaches in inclusive classrooms. Experiences as a moderator were used to see the effect of the co-teaching component. This study used a sampling method that involved 240 respondent’s representatives of the population of SET in Malaysia. The findings of this study showed that there was a high positive tendency in choosing the approach that is likely to progress than the existing ones. In this area, there were challenges and readiness of positive selection than teacher experience. Overall, this study could impact the implementation of co-teaching approach than the implementation of the existing programme.     

Effects of the COVID-19 pandemic on caregiver mental health and the child caregiving environment in a low-resource,rural context

Early child development has been influenced directly and indirectly by the COVID-19 pandemic, and these effects are exacerbated in contexts of poverty. This study estimates effects of the pandemic and subsequent population lockdowns on mental health, caregiving practices, and freedom of movement among female caregivers of children 6–27 months (50% female), in rural Bangladesh. A cohort (N = 517) was assessed before and during the pandemic (May–June, 2019 and July–September, 2020). Caregivers who experienced more food insecurity and financial loss during the pandemic reported larger increases in depressive symptoms (0.26 SD, 95% CI 0.08–0.44; 0.21 SD, 0.04–0.40) compared to less affected caregivers. Stimulating caregiving and freedom of movement results were inconsistent. Increases in depressive symptoms during the pandemic may have consequences for child development.
