Factors that effecting Singapore Tourist Inbound in Malaysia/ Raihan Izzati Md Rashid
No full textThe tourism industry has becoming an important sector in many countries especially in Malaysia. It is because, tourism sector contributes to foreign exchange earnings and Gross Domestic Product per capita. Tourism has been one of the major sources to our country. By tourism, it creates many job opportunities among local worker and it reduce the number of employment in our country. The objective of the study is to gain knowledge and information about the factor that affecting the increasing number arrival of Singapore tourist in Malaysia. In this study, the factors that have been listed are exchange rate factor and Gross Domestic Product per capita factor. The study is focusing if exchange rate for Singapore and Malaysia and Gross Domestic Product from Singapore that gives the effect on the increasing total arrival of Singapore tourist in Malaysia. This factor is gain from Singapore currency and Singapore Gross Domestic Product per capita as income. Time series data is used to measure the variable in this study from year 2008 until year 2016. In this study, the data used is quarterly data every year in order to gain significant result

Travel guide as a medium to improve English comprehensiveness / Nurul Aiesyah Ahmad Shukrima and Raihan Md Ghazali
No full textGuidebooks have been one of the most popular genres of travel literature throughout the world for decades. The contents of the guidebook are likely to be used by people of all ages for various purposes, as it contains diverse information ranging from historical sites to tourist attractions. Travel guidebooks, whether digital or physical, are intended to assist readers in avoiding uncertainty, yet most of those currently on the market have failed to do so. As a result, it could be difficult to immerse oneself in the reading as the length and complexity of guidebooks typically cause the problem. In this study, the author aspired for travel guidebooks to be straightforward and concise because they are a promising option for boosting users' English proficiency. In order to provide trustworthy and solid evidence, the study collected quantitative data using surveys, resulting in a positive finding among respondents regarding short yet compact travel guidebooks as the language and content are easier to comprehend

Enhancement of thermoelectric properties for doped skutterudites based on CoSb3 through ball milling parametric optimization / Md Ovik Raihan
No full textIn search for green energy harvesting materials, thermoelectric technology has been identified as a promising technology to generate electricity from waste heat through the presence of a temperature gradient. Skutterudite a viable candidate for high performance thermoelectric material given its advantages of modifying its structure such as doping, filling, substitution in its cage structure to achieve high performance; making its one of the sophisticated member of the thermoelectric application. In this work a new composition of Bi doped and Fe substituted Co3Sb12 system was successfully synthesized by two step process namely ball milling and spark plasma sintering. The ball milling process produce nanostructures. Which are expected to give superior TE properties through reduction in thermal conductivity. Three different ball milling time were investigated: 10h, 15h, 20 h and their correlation to the thermoelectric properties studied in this thesis. Introduction of the Co and Bi with heat treatment resulted in a successful formation of Bi-0.6FeCo3Sb12 skutterudite. Which is expected to give better thermoelectric performance through substitution of Co with Fe and the Bi doping. The phase structure and morphology of the bulk samples were examined by X-ray diffraction (XRD) and scanning electron microscopy integrated energy-dispersive X-ray spectroscopy analysis (SEM-EDS), respectively. . Rietveld analysis of its XRD spectra indicated that the Bi doping on the Co4Sb12 based skutterudite succeeded in partially filling the voids of the skutterudite, whilst the Fe doping partially substituted the Co sites in the lattice. The thermoelectric properties of the Bi filled and Fe substituted bulk samples were measured in a temperature range of 373 K to 673 K. Evidently all of the Bi doped and Fe substituted samples showed a dominant phase of CoSb3 skutterudite. Comparative study among the Bi filled, Fe substituted samples were done. The ball milling times was correlated to the resulting microstructure, and ultimately, its thermoelectric performance. It was found that the moderate ball milling times (at 15 hours) resulted in the best electrical conductivity of 122K Ω-1m-1 at 373 K, given the homogenous distribution of particles. A Maximum ZT value was observed 0.17 for 10 h ball milled sample at 673 K, whilst almost the same value was achieved for the 15 h ball milled sample , i.e ZT =0.169 at 673 K. This work provides a pathway for improvement of the electrical conductivity and decreasing the thermal conductivity, and is thus a useful strategy for future design of skutterudite materials for thermoelectrics. The analysis of the effect of the ball milling conditions on the thermoelectric performance of this formulations also gives insight to the optimal conditions which may yield a good microstructure, and hence good thermoelectric performance. It has been shown that moderate milling times will provide a well distributed sample which is conducive for good electrical conductivity and low thermal conductivity. This work also demonstrated that milling time is able to affect the final composition of the skutterudite in terms of the amount of Bi filling, despite using the same nominal composition for all three samples
Determinants of Audit Fees: Evidence from Pharmaceutical and Chemical Industry of Bangladesh
No full textThe main objective of this study is to find out the factors that determine the audit fees in the listed pharmaceuticals and chemicals companies of Bangladesh. The study is conducted on 21 listed companies in the pharmaceuticals and chemicals industry during the period of 2015 to 2018. Client characteristics client size, leverage and return on assets , client's governance structure independent directors and audit committee and firm ranking are taken as the proxy variables of the determinants of audit fees. The study has found that client size, leverage and firm ranking have positive and significant impact on audit fees of the sample firm. On the other hand the proportion of independent directors in the board has a negative and significant impact on audit fees. However, the study did not find any significant association between audit fees and return on assets. It is suggested that policymakers should include more independent directors in the board for ensuring better governance to reduce the external audit fees. Besides, in case of maintaining obligatory audit committee, companies should consider the efficiency and effectiveness of the committee. Md.

Poverty dynamics in Bangladesh during the COVID-19 pandemic:who falls back and who graduates out?
No full textIn this paper, we attempt to explain the impact of the COVID-19 pandemic on the poverty dynamics in Bangladesh. We use unique nationally representative panel data with rounds from 2018 and 2020 household surveys conducted by the South Asian Network on Economic Modeling (SANEM) to understand what factors caused households to fall into poverty as the pandemic hit in 2020 and also what factors helped them graduate from their poverty status in 2018. Fixed Effects Multinomial Logit through the Generalized Struc-tural Equation Model (GSEM) was applied to analyze the fallback and graduation dynamics of poverty. Our results show that households from rural areas, regions such as Rangpur or Rajshahi, female-headed households, households with day labourers as primary earners, etc., increase the likelihood of falling back into poverty or vulnerable poverty in 2020 from being non-vulnerable non-poor in 2018. In contrast, being from urban areas, having households from regions other than Rajshahi or Rangpur, households with non-agriculture primary income sources, and households with better housing conditions are more likely to move out to upper poverty status even during this pandemic. Based on these results, this paper recommends that social safety net programmes be designed to support vulnerable groups, such as female-headed households and daily labourers, particularly in regions like Rangpur and Rajshahi. Furthermore, policies should protect investments in education and health to prevent higher dropout rates and expand social safety net programmes to include those newly impacted by employment disruptions
