From Conventional Accounting to Islamic Accounting Does IT Need a Slight or an Extensive Overhaul

Most of Muslim scholars that involve in the development of accounting based Islamic teachings agree on the need of an Islamic accounting for the development of accounting and Auditing institution. This has been exercised in the development of accounting and Auditing Standard for Islamic Financial Institution (AAOIFI. However to what extent the overhaul should be made to obtain an Islamic accounting is subject to debate among those scholars . The debate ranges from the need of slight changes on conventional accounting to the extensive changes on conventional accounting. This paper analyzes both opinions based on their ability to achieve the Islamic socioeconomic objective

Individual, community and region level predictors of insecticide-treated net use among women in Uganda: a multilevel analysis.

BackgroundUse of insecticide-treated net (ITN) has been identified by the World Health Organization as an effective approach for malaria prevention. The government of Uganda has instituted measures to enhance ITN supply over the past decade, however, the country ranks third towards the global malaria burden. As a result, this study investigated how individual, community and region level factors affect ITN use among women of reproductive age in Uganda.MethodsThe 2018-2019 Malaria Indicator Survey of Uganda involving 7798 women aged 15-49 was utilized. The descriptive summaries of ITN use were analysed by individual, community and region level factors. Based on the hierarchical nature of the data, four distinct binomial multilevel logistic regression models were fitted using the MLwiN 3.05 module in Stata. The parameters were estimated using the Markov Chain Monte Carlo (MCMC) estimation procedure and Bayesian Deviance Information Criterion was used to identify the model with a better fit.ResultsThe proportion of women who use ITN was 78.2% (n = 6097). Poor household wealth status [aOR = 1.66, Crl = 1.55-1.80], knowing that sleeping under ITN prevents malaria [aOR = 1.11, Crl = 1.05-1.24] and that destroying mosquito breeding sites can prevent malaria [aOR = 1.85, Crl = 1.75-1.98] were associated with higher odds of ITN use. ITN use attributable to regional and community level random effects was 39.1% and 45.2%, respectively.ConclusionThe study has illustrated that ITN policies and interventions in Uganda need to be sensitive to community and region level factors that affect usage. Also, strategies to enhance women's knowledge on malaria prevention is indispensable in improving ITN use

ENHANCING OF STUDENTS’ MATHEMATICAL REFLECTIVE THINKING ABILITY THROUGH KNOWLEDGE SHARING LEARNING STRATEGY IN SENIOR HIGH SCHOOL

This study aims to find out enhancement of students’ mathematical reflective thinking ability through knowledge sharing learning strategy in Senior High School. The method of study used quasi experiment by non-equivalent control group design. The population of this study are eighth grader students of Senior High School in Tangerang City, Banten Province. Sampling technique used cluster random sampling with the numbers of students are 140 students. The instruments used in the form prior mathematical knowledge test and mathematical reflective thinking ability test. Data analysis are done by requisite test, namely data normality test (Kolmogorov-Smirnov Z Test) and homogeneity test (Levene Test). The statistic analysis of the data was conducted with one-way ANOVA, two-way ANOVA, and Scheffe Test. The results of study are as follows: (1) there is enhancement difference of mathematical reflective thinking ability of the students learning with knowledge sharing strategy and conventional learning; (2) there is enhancement difference of mathematical reflective thinking ability between students learning with knowledge sharing strategy (KSS) and conventional learning based on school level and prior mathematical knowledge (MPK) of students (higher, middle, lower); (3) The interaction between learning strategy (KSS) and prior mathematical knowledge (higher, middle, lower) influenced student’s enhancement of mathematical reflective thinking ability

Specifying Asymmetric STAR models with Linear and Nonlinear GARCH Innovations: Monte Carlo Approach

Economic and finance time series are typically asymmetric and are expected to be modeled using asymmetrical nonlinear time series models. Smooth Transition Autoregressive (STAR) models: Logistic (LSTAR) and Exponential (ESTAR) are known to be asymmetric and symmetric respectively. Under non-normal and heteroscedastic innovations, the residuals of these models are estimated using Generalized Autoregressive Conditionally Heteroscedastic (GARCH) models with variants which include linear and nonlinear forms. The small sample properties of STAR-GARCH variants are yet to be established but these properties are investigated using Monte Carlo (MC) simulation. An MC investigation was conducted to investigate the performance of selections of STAR-GARCH models by classical nonlinear selection approaches. The ARCH(1) and GARCH(1,1) models were the linear GARCH specifications while the Logistic Smooth Transition-ARCH (LST-ARCH(1,1)), Logistic Smooth Transition- GARCH (LST-GARCH(1,1)) and Asymmetric Nonlinear Smooth Transition-GARCH (ANST-GARCH(1,1)) models were the nonlinear GARCH specifications. The nonlinearity parameter in the variance equations and Autoregressive (AR) parameters were varied along with different sample sizes. With the assumption of normality, the results showed that the selection of LSTAR models were actually affected by the structure of the innovations and this improved as sample size increased. Misspecification tests showed that these models cannot be misrepresented in the real sense
