The results showed as follows: firstly, as farmers are transforming from pure agriculture to non-agriculture, their agricultural livelihood diversification index will decrease, while non-agricultural livelihood diversification index will increase. In term of livelihood activities, pure agricultural farmers are exclusively engaged in agricultural activities, agricultural-dominant and non-agricultural-dominant farmers are engaged in both agricultural and non-agricultural ones, while non-agricultural farmers are basically engaged in off-farm activities. Secondly, as for crops planted, pure agricultural and agricultural-dominant farmers tend to choose those crops with more investment,shorter growth period and higher value, meanwhile non-agricultural-dominant farmers tend to choose crops with less investment, simpler management and longer growth period. Thirdly, to cope with current problems in farming, pure agricultural farmers will adopt measures such as changing planting structure, maintaining or expanding planting scale, increasing planting investment and renting in more land to promote the development of farming; agriculture-dominant farmers will adopt measures such as changing planting structure, reducing planting scale, maintaining planting investment, renting in and taking back the leased land as well as engaging in non-agricultural activities to overcome the difficulties faced; while non-agricultural-dominant farmers will adopt measures such as reducing both planting scale and investment,changing planting structure and engaging in farmland transfer as well as various offfarm activities to avoid livelihood risks.展开更多

It is important to distinguish noncirrhotic from cirrhotic causes of ascites to guide therapy in patients with noncirrhotic ascites. Mild to moderate ascites is treated by salt restriction and diuretic therapy. The diuretic of choice is spironolactone. A combination treatment with furosemide might be necessary in patients who do not respond to spironolactone alone. Tense ascites is treated by paracentesis, followed by albumin infusion and diuretic therapy. Treatment options for refractory ascites include repeated paracentesis and transjugular intrahepatic portosystemic shunt placement in patients with a preserved liver function. Potential complications of ascites are spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). SBP is diagnosed by an ascitic neutrophil count > 250 cells/mm3 and is treated with antibiotics. Patients who survive a first episode of SBP or with a low protein concentration in the ascitic fluid require an antibiotic prophylaxis. The prognosis of untreated HRS type 1 is grave. Treatment consists of a combination of terlipressin and albumin. Hemodialysis might serve in selected patients as a bridging therapy to liver transplantation. Liver transplantation should be considered in all patients with ascites and liver cirrhosis.展开更多

The Horton equation is one of the popular models used in the characterization of field infiltration. In this study, the least square curve firing technique was employed to estimate the model parameters from fifteen field measured data and gave resultant mean regression coefficients (R2) value of 0.811. Furthermore, plotting the measured against the calculated infiltration rate for the first six (6) measurement points yielded R2 values close to unity in the regression curve indicating a marked relationship between the two. This indicates that the Horton infiltration model can be applied to estimate infiltration characteristics of soils in Samaru, Northern Guinea Savanna of Nigeria.展开更多

The quality level of this accounting information comes from the company's governance practices, thereby emphasizing the importance of corporate governance in companies. Recently, following the financial crises resulting in accounting scandals, attention has been moving towards internal audit function as an important factor in the structure of corporate governance. This paper therefore examined the extent of the relationship between internal audit function and the quality of accounting information of companies. The study adopted the survey research design. The research instrument employed was questionnaire which was administered to internal auditors of the "Big Four". Linear regression analysis was employed in the analysis of the data collected with the use of Statistical Packages for Social Sciences (SPSS). The results revealed that there is a significant relationship between the internal audit characteristics and the quality of accounting information. It was recommended that in order to provide credibility to the financial statement, there should be a law in place mandating attachment of internal auditors report to the financial statement.展开更多

The organic CAS represents food quality without the use of synthetic chemicals to protect consumers' health. As a consequence, production costs and consumer prices have increased. The aim of this study is to analyze consumers' perception of the organic CAS label and how purchasing behavior for the product is influenced by converting the Fresh Milk Logo to the organic CAS certified label, which is based on contingent behavior analysis. This study adopts factor analysis to extract the perceptions and preferences of the respondents. In addition, the on-site Poisson model to revise the truncated and endogenous stratification and assess consumer welfare precision. The incremental consumer surplus for consumer consumed organic fresh milk is approximately NT$8,979.展开更多

To improve resource utilization under well-studied fairness constraints, we propose a new allocation mechanism called Dominant Resource with Bottlenecked Fairness(DRBF), which generalizes Bottleneck-aware Allocation(BAA) to the settings of Dominant Resource Fairness(DRF). We classify users into different queues by their dominant resources. The goals are to ensure that users in the same queue receive allocations in proportion to their fair shares while users in different queues receive allocations that maximize resource utilization subject to well-studied fairness properties such as those in DRF. Under DRBF, no user 1) is worse off sharing resources than dividing resources equally among all users; 2) prefers the allocation of another user; 3) can improve their own allocation without reducing other users' allocations; and(4) can benefit by misreporting their resource demands. Experiments demonstrate that the proposed allocation policy performs better in terms of high resource utilization than does DRF.展开更多

External tax audit has been purported to enhance tax administration efficiency, deter tax evasion and noncompliance as well as improve tax collection for a nation. Therefore, this study solicits perceptions from various stakeholders on the new service while retaining the principle of justice that lies in the tax system. External tax audit refers to the process of business income tax returns being attested by other than the tax authority. External tax audit has been implemented successfully to increase tax compliance in some areas such as Taiwan, Bangladesh and United States of America. Therefore, this study examines the benefits and risks influencing the implementation of external tax audit in Malaysia from the viewpoints of corporate taxpayers and tax agents. Data is obtained through questionnaire from the selected respondents. Findings from multiple regression analysis reveal that tax agents and taxpayers agree with the implementation of this new service. For tax agents, the external tax audit has benefits and risks, while taxpayers believe that only benefits influence their agreement to the external tax audit. This study contributes to the tax literature by providing knowledge on the feasibility of external tax audit implementation in Malaysia.展开更多
