To achieve these objectives, a questionnaire was developed and distributed to respondents from audit firms in Bahrain. Descriptive statistics were used to analyse the influence of auditor-client association upon quality of audit and auditor independence and how audit quality and auditor independence are improved was also explored in the study. The results show that all the questions (1-8) in the questionnaire impair both audit quality and auditor independence with the means ranging from 3.6000 to 4.0364 with an average mean of 3.7212. According to the measurement scale, any item with a mean of 3.50 or more is acceptable, and since all the influences are above 3.50, they are all acceptable. Regarding how auditor-client relationship (or long tenured auditor) would improve both quality of audit and auditor independence, the results show that all the questions (9-17) would improve both audit quality and auditor independence with the means ranging from 3.6364 to 4.0727 with an average of 3.8646, which are acceptable. These results confirm statistically that there is a significant relationship between the auditor long-term tenure and audit quality and auditor independence, so the null hypothesis (H0) is rejected and the alternative hypothesis is accepted. Simple regression analysis is employed to test the hypothesis of the study and its significance. The results show that (H0) hypothesis is not significant. Therefore, the alternative hypothesis (H1) is significant at p 〈 0.005, which means that there are differences in viewpoints among respondents and the p-value obtained is 0.044 which is less than the significant value of p 〈 0.05. These results confirm the hypothesis that a significant relationship exists between the auditor long-term tenure and quality of audit and auditor independence.展开更多

Effectively beekeeping today means using several pastures per year with a yield of 50-60 kg per hive. Mobile beekeeping is the only way to achieve high yields of production and it has considerable advantage over stationary one which is less rentable. Mobile beekeeping require higher investments and labor but with good climate and ecological conditions, one can achieve several times higher income than in stationary beekeeping. Some of the success in mobile beekeeping depends of the selection of hives. The hives must be designed to give the bees the best environment for work and development to be most efficient. Data was collected from 57 beekeepers that live in the district. Data analysis was conducted by using standard statistical and economic processes. Criteria for a recommended for the proposed beekeeping model were incomes and profit per hive. For effective beekeeping and production of bee products, especially honey, beekeeper must have adequate equipment and a good bee hives. Beekeeper must have transportation and additional equipment because their movement depends season on the season and distance to pasture.展开更多
