Older Women and Lower Self-Rated Health

Several studies have found that older women report lower self-rated health than men. However, it is not clear why older women are more likely to report poor self-rated health than older men. Data for this study came from a national cross-sectional survey, Mental Health and Quality of Life of Older Malaysians (MHQoLOM). Included in the survey were 2980 respondents consisting of Malaysians aged 60 years and over, with both men (n = 1428) and women (n = 1552) represented. Results of t-tests showed older men expressed significantly higher levels of self-rated health and self-esteem than women (p < .01). Separate multivariate regression by gender revealed that age, life-threatening problems, and self-esteem were highly significant predictors of self-rated health among older men and women and explained 18.4% of variance in self-rated health for men and 18.2% for women. In the last step we examined the main effects of gender on self-rated health using General Linear Models (GLM) Univariate by adjusting for age, life-threatening problems, and self-esteem. Results showed an insignificant difference in self-rated health between older men and women (F _(1,2715) = 2.26, P = 0.13) only after adjusting for self-esteem. It can be concluded that self-esteem affects responses to self-rated health of older men and women.     

Cardioprotective activity of synthetic guggulsterone (E and Z-isomers) in isoproterenol induced myocardial ischemia in rats: A comparative study

Guggulsterone, a mixture of cis (E) and trans (Z) isomers (7∶3 w/w) was synthesized from 16-DPA. The isomers were separated by column chromatography and evaluated for cardioprotective and antioxidant activities. Myocardial necrosis induced by isoproterenol in rats caused marked increase in serum creatine phosphokinase and glutamate pyruvate transaminase. Simultaneously in ischemic heart, phospholipase, xanthine oxidase and lipid peroxides were enhanced following depletion of glycogen, phospholipids and cholesterol. Treatment with guggulsterone and its both isomers at the dose of 50 mg/kg po., significantly protected cardiac damage as assessed by the reversal of blood and heart biochemical parameters in ischemic rats. The cardioprotective activity of guggulsterone and of both the isomers were compared with that of gemfibrozil at the same doses. Guggulsterone and both the isomers at tested concentrations (5–20mM) inhibited oxidative degradation of lipids in human low-density lipoprotein and rat liver microsomes induced by metal ionsin vitro. The drug counteracted against the generation of superoxide anions (O₂) and hydroxyl radicals (OH⁻) in non-enzymic test systems. It is suggested that cardioprotective and antioxidant activities of synthetic guggulsterone and guggulsterone obtained from gum resinCommiphora mukul that contains isomers E & Z in the ratio of 46∶54w/w are the same.     

Students’ Perceptions of Their Science Teachers’ Pedagogical Content Knowledge

Pedagogical content knowledge (PCK) is a type of teacher knowledge to be developed by a teacher. PCK is said to contribute to effective teaching. Most studies investigated the development of PCK and its influence on students’ learning from the teachers’ perspectives. Only a limited number of studies have investigated the components of science teachers’ PCK that helped students’ learning from the perspective of students. Thus, it is the aim of this study to investigate the level of science teachers’ PCK from students’ perspective, in particular whether or not students of different achieving ability had different views of teachers’ PCK in assisting their learning and understanding. Based on the PCK research literature, six components of PCK have been identified, which were as follows: (1) subject matter knowledge, (2) knowledge of teaching strategies, (3) knowledge of concept representation, (4) knowledge of teaching context, (5) knowledge of students, and (6) knowledge of assessment in learning science. A questionnaire consisting of 56 items on a five-point Likert-type scale were used for data collection from 316 Form Four students (16 years old). One-way analysis of variance revealed that the differences in science teachers’ PCK identified by students of different achieving abilities were statistically significant. Overall, students of various academic achieving abilities considered all the components of PCK as important. The low-achieving students viewed all the components of PCK as being less important compared to the high and moderate achievers. In particular, low-achieving students do not view ‘knowledge of concept representation’ as important for effective teaching. They valued the fact that teachers should be alert to their needs, such as being sensitive to students’ reactions and preparing additional learning materials. This study has revealed that PCK of science teachers should be different for high and low-achieving students and knowledge of students’ understanding plays a critical role in shaping teachers PCK.     

Practical stability in terms of two measures for fractional order dynamic systems in Caputo's sense with initial time difference

The initial time difference practical stability in terms of two measures has been investigated for nonlinear fractional differential equations in Caputo's sense and these properties have been unified with Lyapunov-like functions to establish a comparison result.     

Relationship Between Teacher Factors and Student Achievement： A Correlational Study of Secondary Schools

Teachers always played a significant role in the intellectual and moral development of students by using various techniques, assessments, and methods to improve student achievement in school＇s subjects. This study therefore focuses on the effect of teacher factors, such as assessment interval, communication language, the distance of residence, and the teacher＇s personal characteristics （gender, age, academic and professional qualification, designation, experience, and in-service training） on the 9th grade students＇ achievement in three subjects （English, Chemistry, and Mathematics at secondary level）. The population of the study is comprised of all ＂public sector＂ secondary schools, male and female teachers, and boy and girl students. A total number of 16 secondary schools （eight for boys and eight for girls）, 114 secondary school teachers （66 males and 48 females）, and 2,404 students （1,400 boys and 1,004 girls） were selected through purposive sampling techniques. Multiple statistical procedures, Spearman and Pearson correlation, mean, and standard deviation were employed to obtain stronger validity to the study. The results of the study identify weak and negative weak relationship between most of the teacher factors and student achievement in three subjects but the relationship between students＇ background and learning achievement in all three subjects were found positively correlated.     

Gross motor coordination in junior tennis players

The purpose of this study was twofold: (1) to determine the gross motor coordination performance levels of junior tennis players and (2) to analyse the effects of age and gender. Participants were junior male (n = 50) and female (n = 51) tennis players aged 6–14. Körperkoordinationstest für Kinder (KTK) was used to assess the gross motor coordination of the participants. Results revealed that none of the participants performed lower than normal level in motor coordination. Besides, 40.6% of the participants performed above normal level. No gender differences were found on all subtests of KTK and also on total motor quotient. Although older players performed better on each test than their younger counterparts for the raw scores, no significant age effect was observed on motor quotient scores among different age groups.     

Bridging identities through religious television contents: Javanese female descendants,Islamic viewing and Malay identity projection

This study explores the uses of Islamic television content in bridging the gap between Javanese and Malay identity among the Malay women of Javanese descent in Malaysia. Malaysian religious television programmes have constantly promoted the Islamic identifications of Malayness, enabling the Malay audience to reconstruct the culturally religious identity. While the reconstruction of Islamic identity through television viewing simply represents a lived experience for the majority of the Malay society, it has some cultural meanings for certain Malay sub-ethnic communities, such as the Javanese. This ethnographic study on a Malaysian Javanese community reveals that the interpretive engagement of this particular community in Islamic television viewing serves the purpose of negotiating Malay identity. The results of this study suggest that religious content can serve as an engaging platform to construct multi-ethnic identities beside popular and ethnic-related contents.     

Animated Introductory Calculus： Development and perception

Recent years it has an explosive development of IT technologies. However, the problem of natural integration of modern technologies in teaching and learning mathematics is far from its final solution. In teaching mathematics at universities, these capabilities either are ignored or have extremely limited applications. In our study, we consider animation as one of the tools that could increase students＇ motivation, curiosity and understanding. In order to evaluate the perception about using animation in the study of calculus, a brief survey was conducted in University Utara Malaysia （UUM）. The survey consisted of 17 lecturers and 25 students from UUM. The survey also conducted in UPM （University Putra Malaysia） and UniKL （University Kuala Lumpur）, which comprised of 82 students and 49 students respectively. At the same time, we are interested in whether or not the perception of students differs by factors like gender, age group, entry qualification, program of study and previous grades. This survey was conducted in UPM comprised of 160 students. In this paper, we describe our data and report our findings, make a comparison between students＇ perception in UPM, UUM and UniKL. Further a comparison is also made regarding perception of UniKL students from two different programmes of study. To evaluate the performance of students, a simple comparative experiment between Computer Aided Learning Method （CALM） and the Traditional Learning Method （TLM） conducted in UUM and UPM and we report our preliminary findings in this paper.
