Issues In Stock Index Futures Introduction And Trading. Evidence From The Malaysian Index Futures Market.

This paper examines several issues related to the introduction and trading of stock index futures contracts in Malaysia. Issues related to volatility, pricing efficiency, systematic patterns and lead-lag relationships are examined. These issues were studied by way of addressing six research questions. We use two data sets. First, daily price data for 4 years and 2 years respectively for stock and futures markets and second, intraday, 15 minute interval data for 43 days (2 months) of futures trading. Based on our results, we find no evidence of any increase in the volatility of the underlying market following futures introduction. If anything, the one year period following futures introduction had lower volatility. Intermarket comparison showed futures volatility to be higher. No evidence of any expiration day effect was found. We find frequent mispricing, with most of it being underpricing. Including transaction costs showed very little mispricing. Analysis of the 15 minute intraday data showed clear evidence of an overall U-shape in futures volume and volatility. However, a minor third peak at reopening following lunch break was also evident. We find no evidence of a lead-lag relationship, rather a contemporaneous one. Both markets appear to react simultaneously to information arrival.Impact of the introduction of Stock Index Futures Contracts on the underlying equity market

Aplikasi Analisis Faktor dengan Metode Principal Component Analysis dan Maximum Likelihood dalam Faktor-faktor yang Memengaruhi Pemberian Makanan Tambahan pada Bayi Usia 0-6 Bulan di Desa Pematang Panjang Kecamatan Air Putih Kabupaten Batubara Tahu

Factor analysis is one of the multivariate statistical analysis techniques.This analysis is included in the interdependence technique with the aim of reconciling data in a grouping or the formation of a new set of variables which is named factor. The parameter estimation that is commonly used in this analysis is the principal component analysis method and the maximum likelihood method. This research aims to know the comparison of suitability of the model by principal component method and maximum likelihood method within the factors that affect the complementary feeding in infants ages 0-6 months in Pematang Panjang Village Air Putih Subdistrict Batubara District 2013. Based on its purpose, this research is implementative research and based on its explanation level it is comparative research. The population of the research was all mothers who have baby in age of 0-6 months which are as many as 52 persons. The sampleis all population made as sample. The result of factor analysis using the principal component analysis method forms factor 1 (education, culture, economy, job, and mother's health) and factor 2 (knowledge, baby's health, and health/medical officer), while the result of factor analysis using maximum likelihood method forms factor 1 (education, culture, economy and job) and factor 2 (knowledge, baby's health, mother's health and health/medical officer). Research results by using analysis of factors suggest that the maximum likelihood method has a better model accuracythan the principal component analysis method, because the RMSE value of maximum likelihood method which is 0,0222 < RMSE value of principal component analysis method which is 0,0409. It is suggested to the next research which uses factor analysis aplication that it is better to firstly see the result of the analysis using principal component analysis and maximum likelihood methods and then using method with less RMSE value

In utero exposure to malaria is associated with metabolic traits in adolescence: The Agogo 2000 birth cohort study.

OBJECTIVES: Malaria in pregnancy (MiP) contributes to fetal undernutrition and adverse birth outcomes, and may constitute a developmental origin of metabolic diseases in the offspring. In a Ghanaian birth cohort, we examined the relationships between MiP-exposure and metabolic traits in adolescence. METHODS: MiP at delivery was assessed in 155 mother-child pairs. Among the now teenaged children (mean age, 14.8 years; 53% male), we measured fasting plasma glucose (FPG), body mass index (BMI), and systolic and diastolic blood pressure (BP). Associations of MiP with the adolescents' FPG, BMI, and BP were examined by linear regression. RESULTS: At delivery, 45% were MiP-exposed, which increased FPG in adolescence, adjusted for mother's age at delivery, parity and familial socio-economic status (infected vs. uninfected: mean ΔFPG = 0.20 mmol/L; 95% confidence interval (CI): 0.01, 0.39; p = 0.049). As a trend,this was discernible for BP, particularly for microscopic infections (mean Δsystolic BP = 5.43 mmHg; 95% CI: 0.00, 10.88; p = 0.050; mean Δdiastolic BP = 3.67 mmHg; 95% CI: -0.81, 8.14; p = 0.107). These associations were largely independent of birth weight, gestational age and teenage BMI. Adolescent BMI was not related to MiP. CONCLUSIONS: In rural Ghana, exposure to malaria during fetal development contributes to metabolic conditions in young adulthood

Culture and Food Security of The Mowewe Community During The Covid-19 Pandemic

Food is a critical aspect of community resilience. The Covid-19 pandemic, however, has affected the natural environment, making food supply scarce and ultimately impacting economic and national stability. Despite this, the Mowewe community shares a local culture by which its people get empowered to maintain food security. Therefore, this study aims to discover and describe the local community's culture in Mowewe District in establishing a food security system. The method used was ethnography with a qualitative approach. Data were collected through participant observation, in-depth interviews, and documentation, after which the data were analyzed using qualitative descriptive techniques. The findings revealed that the local culture of the Mowewe community was built upon the concept of Mekambare, principles of gotong royong (cooperation), and ecological adaptation. The Mowewe community was of deep concern for the pattern of life balance during the pandemic. They took advantage of natural resources by clearing agricultural land to grow rice, corn, patchouli, and sago and keeping bees in the forest to produce honey for an additional source of income and immunit

Single channel magnetic induction spectroscopy technique for fetal acidosis detection

Current fetal acidosis diagnosis needs an invasive measurement which required a doctor to puncture fetal scalp to acquire blood pH. This method introduced risk to the fetal which fetal scalp may bruise and infected. This paper discusses a noninvasive method employing a single channel magnetic induction spectroscopy technique as an alternative method to diagnose acidosis in fetal without puncturing the fetal scalp. The studies are based on numerical simulation models to investigate the most feasible sensor coil that is sensitive and effective to be implemented in hardware setup as the shape of coil influences directly the sensing performance of the magnetic induction spectroscopy system. The study has found that the circular coil is more sensitive than linear coil. The system tested with different pH samples to mimic the blood pH value. The result is very promising with good correlation approaching 1 has been achieved. Therefore, magnetic induction spectroscopy technique has good opportunity to be applied as an alternative method to detect acidosis in the fetal with circular coil is performed as the best sensing coils for MIS hardware

Extracellular Protein Secreted by Bacillus subtilis ATCC21332 in the Presence of Streptomycin Sulfate

The extracellular proteins secreted by bacteria may be increased in stressful surroundings, such as in the presence of antibiotics. It appears that many antibiotics, when used at low concentrations, have in common the ability to activate or repress gene transcription, which is distinct from their inhibitory effect. There have been comparatively few studies on the potential of antibiotics as a specific chemical signal that can trigger a variety of biological functions. Therefore, this study was carried out to determine the effect of Streptomycin Sulfate in regulating extracellular proteins secreted by Bacillus subtilis ATCC21332. Results of Microdilution assay showed that the Minimum Inhibition Concentration (MIC) of Streptomycin Sulfate on B. subtilis ATCC21332 was 2.5 mg/ml. The bacteria cells were then exposed to Streptomycin Sulfate at concentration of 0.01 MIC before being further incubated for 48h to 72 h. The extracellular proteins secreted were then isolated and analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Proteins profile revealed that three additional bands with approximate sizes of 30 kDa, 22 kDa and 23 kDa were appeared for the treated bacteria with Streptomycin Sulfate. Thus, B. subtilis ATCC21332 in stressful condition with the presence of Streptomycin Sulfate at low concentration could induce the extracellular proteins secretion
