This study seeks to understand the relationship between audit committee effectiveness and audit fees. Prior literature suggests two perspectives to explain this relationship; the first is demand based whereas a positive relationship is expected, while the second is audit risk which propose a negative relationship between the two variables. In order to test the relationship between the two variables, data were collected from 64 companies listed in Abu Dhabi Securities Exchange and Dubai Financial Market. Univariate and multivariate analyses were conducted to test the hypotheses of the study. Results showed that audit committee effectiveness has a significant positive impact on audit fees. This result supports the demand based perspective to explain the relationship between audit committee effectiveness and audit fees. Also, a significant positive relationship is reported for number of meeting of audit committees and audit committee members financial expertise with audit fees.

Specific and Destination Websites of UNESCO Heritage Sites (WUHS) located in France, Italy and Spain are analyzed to investigate if the management of UNESCO is able to promote heritages efficiently in the World Wide Web. Empirical evidence supports the idea that WUHS ranking depends on the type and localization of the site and the quantity and quality of WUHS information influences the time spent by a user visiting a website-page. Therefore, managers could be able to improve the role of websites through: a) a more efficient and incisive promotion of a site or a destination; b) a WUHS design based on target markets’ needs and the type of information that markets perceive as useful. An “adequate” WUHS is thus intended as a virtual place where tourists can find all the relevant information.

This paper will present an investigation of inter-regional mobility in patients with a diagnosis of cancer. By virtue of the availability of geocoded information relating to a patient's place of residence, the effect of socio-economic status and other individual characteristics regarding inter-regional mobility will be analysed by means of multilevel logit models. The results demonstrate the influence of age and comorbidity on mobility propensity, in addition to the treatment type, which plays a role in patient mobility. As contextual determinants, patients residing in less deprived areas show greater mobility than those who reside in materially deprived areas. The extent of patient mobility, and its dependence on their socio-economic status raises issues of equity, as well as regional policy considerations.

This paper introduces a generalization of moment exponential distribution so called Kumaraswamy Moment Exponential (KwME) distribution. The limit behaviour of its density and hazard functions are described. Some properties of the proposed distribution are discussed including moments, skewness, kurtosis, quantile function, and mode. Characterizations based on truncated moments and hazard function are presented. Renyi and q-entropies, mean residual life (MRL) and mean inactivity time (MIT) of X, and order statistics are determined. The maximum likelihood estimation (MLE) is used to estimate the model parameters. Two real data sets are used to compare the KwME distribution with other competitive models and concluded that it could serve as a better alternative lifetime distribution than existing well known models.

Both during academic work and everyday life it is usual to come across such situations, where one has to compute the difference between values of a variable. However, this can be done many ways. For example, the comparison of accuracy values of methods for the solution of a scientific problem is usually done by either looking at how much the absolute difference between the two accuracies in percentage points is, how much their relative difference in percentages is, or how much the relative difference between the two error rates in percentages is. The problem is that these different methods usually give different results, often suggesting contradicting conclusions. To overcome this problem I propose a novel measure to compute an adjusted difference ( ) between values of a variable to represent their difference in a better and uniform way, replacing the collection of the previously used conventional measures, and show how the properties of this new measure are superior to those of the other measures.

Statistical knowledge and expertise are gaining importance during this era of information and knowledge economy (KE). In addition to the fundamental role they play in R&D, statistical methods and techniques are widely utilized to assess knowledge output and performance of knowledge economies. This paper provides an overview of the use of statistics in the workplace in the United Arab Emirates (UAE), and the role statistics and statisticians play in the country's endeavors to transform to a KE. The paper further elucidates the gap between statistics education and the labor market needs. Information are garnered from a sample of 104 statisticians and practitioners with related backgrounds on several issues covering the level of statistical practice in the country, training and professional development and the role statisticians play in supporting research and decision making. Evidence reveals a growing recognition of the role of statistics in the country. Several limitations, however, were noted including increased shortages in supply of statisticians and a lack of indepth professional training in traditional and emerging statistics topics together with a lack of quality research output.

The recent crisis saw the Italian household cutting consumption spending reshaping expenses behaviours. In this respect the role of macroeconomic fac- tors like institutions has received poor theoretical treatment and is scarcely proven. Based on the Istat Household Budgetary Survey, this paper focuses on the effects of crisis on selected consumption items (energy; healthcare; leisure; travels; eating out) controlling for micro and macro factors, such the Institutional-Quality-Index (IQI) and the regional GDP. IQI emerge as cru- cial in determining household healthcare expenses before the recession: where the local endowment of institutional quality is higher, the private expenses for medical/dental care, pharmaceuticals and diagnostic tests, significantly decrease. The higher the quality of institutional quality, and then of pub- lic health services, the lower the private expenditure. The recession resets the impact of IQI and increases the positive correlation with strictly microe- conomic variables such as income, wealth and the number of household’s earners.

In this paper, we study the transformed Rayleigh Lomax (Trans-RL) distribution which belongs to a certain family of two parameters lifetime distributions given by Wang et al (2010). Confidence intervals and inverse estimators of the Trans-RL parameters are derived in terms of order statistics. A simulation study is conducted to report the coverage probabilities, the average biases and the average relative mean square errors for the maximum likelihood, L-moments and inverse estimators. We compare the performance of these methods under different schemes of progressively Type-II right censoring. Finally, an illustrative example is provided to demonstrate the proposed methods.

Birnbaum-Saunders (BS) distribution is a model with positive domain thatis used in many fields including reliability and environmental studies. Thisarticle introduces a generalized version of the BS distribution which arisesfrom the shape mixture of skew normal distribution. A feasible EM typealgorithm is developed to obtain maximum likelihood (ML) estimates of pa-rameters of the new model. The asymptotic standard errors of ML estimatesare obtained via the information-based approximation. The robustness andapplication of the proposed methodology is illustrated through simulationstudies and air pollution analysis.
