Comparative studies of the rain attenuation predictions for tropical regions

The radio waves propagating through the earth atmosphere will be attenuated due to the presence of atmosphere particles, such as water vapor, water drops and the ice particles. Meanwhile, the atmospheric gases and rain will both absorb and scatter the radio waves, and consequently degrade the performance of the link. The results of various studies conducted in temperate and tropical regions have been published in research papers. This paper presents the summary of comparative studies on different rain attenuation prediction methods for terrestrial microwave links tropical regions. Basically the models described in this paper include those of the ITU-R, revised Moupfouma, revised Silva Mello and Lin model. The objective of this study is to reveal the most suitable rain attenuation prediction model for the Malaysian tropical region. This paper will provide useful information for microwave engineers and researchers in making decision over the choice of most suitable rain attenuation prediction for terrestrial links operating in a tropical region. Even though the ITU-R model underestimates the rain attenuation at higher frequencies, the test results have clearly indicated that it is most suitable for predicting terrestrial rain attenuation in tropical Malaysia, compared to others

Equity market and exchange rate volatility in Asean 5 countries / Prof Madya Dr Mazila Md Yusuf and Hamisah Abd Rahman

Foreign exchange rates have been highly volatile since the abandonment of the fixed exchange rate system in 1973. The volatility of the exchange rate is the source of exchange rate risk and this has certain implications on the economic growth of a country. This is because a rise in exchange rate volatility is said to deters multinational companies and foreign investors from engaging in international activities. When currency appreciates, the sales and profits of exporters will decline and stock prices will drop due to the fact that exporters lose their international competitiveness. On the other hand, importers' competitiveness in domestic market will increase which would lead to the increase in profit and stock prises. The scenarios would be opposite in the case of currency depreciation. Equity markets and foreign exchange markets have been regarded as sensitive segments of the financial market due to the impact of any policy changes gets quickly reflected in both markets. The issue of inter-relation between stock returns and exchange rates has often been discussed by economists since they both play important roles in influencing the development of a country's economy. Changes in stock prices may influence the movements in the exchange rate, via firm's portfolio adjustments [1]. Due to this dynamic interrelationship between the two markets has prompted researchers, policy makers and analysts to carry out detailed analyses of this relationship

Managers Perceptions towards the Success of E-performance Reporting System

Managers are the key informants in the information system (IS) success measurements. In fact, besides the determinant agents are rarely involved in the assessments, most of the measurements are also often performed by the technical stakeholders of the systems. Therefore, the results may questionable. This study was carried to explain the factors that influence the success of an e-performance reporting system in an Indonesian university by involving ± 70% of the managers (n=66) in the sampled institution. The DeLone and McLean model was adopted and adapted here following the suggestions of the previous meta-analysis studies. The collected data was analyzed using the partial least squares-structural equation modelling (PLS-SEM) for examining the four hypotheses. Despite the findings revealed acceptances of the overall hypotheses, the weak explanation of the user satisfaction variable towards the net benefit one had been the highlighted point. Besides the study limitations, the point may also be the practical and theoretical considerations for the next studies, especially for the IS success studies in Indonesi

Keistimewaan pendidikan agama Islam dan pandangan pentadbir British terhadap sistem pendidikan di Tanah Melayu: The Privileges of Islamic religious education and British administrator’s views on the education system in Malaya

Majoriti pentadbir British berpegang dengan falsafah positivisme empirik logik iaitu fahaman yang mementingkan penggunaan akal sepenuhnya sebagai pendekatan utama bagi mendapatkan sesuatu fakta keilmuan dengan tepat berdasarkan kaedah penelitian yang teliti dan sistematik. Falsafah ini menolak pembuktian sesuatu fakta menggunakan sumber wahyu kerana dianggap tidak releven dalam pembuktian sejarah dan telah mewujudkan pandangan yang berat sebelah serta meragukan terhadap masyarakat Melayu di Tanah Melayu. Artikel ini menumpukan kepada analisa terhadap pandangan pentadbir British berkenaan sistem pendidikan di Tanah Melayu merangkumi pendidikan agama dan sekular, dan untuk mengetahui keistimewaan pendidikan agama Islam ke atas masyarakat Melayu. Penulis menggunakan kaedah pensejarahan, perbandingan dan analisis kandungan bagi menyiapkan kajian ini. Hasil kajian mendapati pentadbir British memperkecilkan sumbangan sistem pendidikan agama Islam di Tanah Melayu dan beranggapan kegagalan Tanah Melayu mencapai ketamadunan yang tinggi disebabkan berpegang kepada Islam yang dianggap tidak releven dengan perkembangan semasa. Justeru, bagi memperbaiki kelemahan tersebut perlaksanaan sistem pendidikan Barat dilihat sebagai langkah yang tepat bagi menerapkan fahaman sekularisme ke dalam pemikiran masyarakat Melayu di Tanah Melayu
