Corporate governance, transparency and performance: Empirical evidence from UAE
No full textThis paper uses both the agency theory and the legitimacy theory to provide a complementary framework that links different patterns of disclosures (i.e. transparency) to corporate performance for a sample of 116 United Arab Emirates (UAE) listed firms between years 2008-2016. It investigates the relationship between corporate disclosures (i.e. transparency), organisational commitment to law, a set of governance mechanisms (namely, board size, CEO decision-making power, and foreign ownership) and corporate performance, while controlling for corporate specific characteristics such as size, type, age and leverage. The empirical results show that transparency indices have a puzzling pattern across different performance measures namely return on assets, asset turnover and organisational growth. For the non-financial sector, the results shows a positive significant association with return on assets and asset use, and a significant negative association with organisational growth. For the financial sector, the results show no association between transparency and performance measured by return on assets and asset use, and a negative association with organisational growth. The findings are important to regulators, investors, and researchers aiming at developing new policies that establish better regulatory infrastructure that increases investors confidence. The paper is one of very few studies that examine the association between corporate transparency and corporate performance in an emerging market economy, such as the UAE

Intestinal Parasitic Infections among Intellectually Disabled Individuals in Bandar Abbas County, Southern Iran
No full textIntellectually disabled individuals are more prone to parasitic infections due to their unusual behaviors, immune and nutrient deficiencies, and living conditions. The current study is aimed at evaluating the prevalence of intestinal parasites in institutionalized intellectually disabled individuals in Bandar Abbas County in the south of Iran. Subjects of the study were 119 individuals, living in an intellectually disabled individual care center. Demographic features of the subjects including age, sex, intellectual disability type, and duration of their stay in the center were recorded. A stool sample was taken from each subject and evaluated by direct wet mount and formalin-ethyl-acetate concentration methods. Samples were also examined, using trichrome and modified acid-fast permanent staining. The mean age of the subjects was 27.6 (±2.24), ranging from 4 to 60 years old. Of the 119 participants, 55 (46.2%) were male, and 64 cases (53.8%) were female. Overall, 31 individuals (26.1%, 95% CI: 18.4-34.9) were found to be infected with at least one type of intestinal parasite. Blastocystis hominis, as the most common detected parasite, was detected in 13 (10.1%), Entamoeba coli in 12 (10.1%), Giardia lamblia in 5 (4.2%), Cryptosporidium in 2 (1.7%), Iodamoeba butchlii in 2 (1.7%), and Endolimax nana in 1 (0.8%) of participants. Three cases had coinfection with Blastocystis hominis and Entamoeba coli, one case was infected with Blastocystis hominis and Giardia lamblia, and one case was coinfected with Giardia lamblia and Entamoeba coli. There were no statistically significant associations between intestinal parasitic infection and gender, age, type of intellectual disability, or duration of stay in the care center (P > 0.05). The findings of the present study indicate a relatively high prevalence of parasitic infections in people with intellectual disabilities in Bandar Abbas, southern Iran. Noteworthy is the high prevalence of Blastocyst and also the presence of Cryptosporidium infection in these people. Periodic treatment of these people and improvement of their maintenance conditions can be considered for the prevention and control of intestinal parasitic infection in these people
Accuracy assessment of ultrasonic C-scan and X-ray radiography methods for impact damage detection in glass fiber reinforced polyester composites
No full textThe present study introduces two quantitative parameters to compare the accuracy of ultrasonic C-scan testing and X-ray radiography methods in the damaged area detection under low-velocity impact in polymer-based composites. For this purpose, the hand lay-up technique of composite processing was employed to prepare the composite specimen. A composite specimen consisting of the glass fiber reinforced with the unsaturated polyester resin was considered for this investigation. The impact tests at different energy levels were carried out to create three damaged areas in this composite specimen. Because the glass/polyester specimen had a transparent surface, a digital scanner was used to obtain an ideal image of specimen representing the region and edge of the impacted areas. Two image quality factors were introduced as quantitative parameters to compare the ultrasonic C-scan and X-ray radiography results with those of an ideal image. The results of this study showed that the ultrasonic C-scan is a more accurate method for inspection of the GFRP specimen

A new interval meta-goal programming for sustainable planning of agricultural water-land use nexus
No full textMeta-Goal Programming (MGP) is a simultaneous cognitive evaluation of the degree of achievements for original decision goals considered in a GP model. However, in most real-world situations, environmental coefficients and related parameters are not easily available. In such a situation, the decision-maker must consider various conflicting targets in a framework of uncertain aspiration levels at the same time. On the other side, Interval Programming (IP) is a method used to increase the range of available decision-maker preference structures in GP. In the perspective of solving the conflicts between agriculture and water use towards sustainability, this paper proposes an Interval Meta-Goal Programming Model (IMGPM) dealing with imprecision in data that covers interval coefficients, target intervals, and interval bounds of meta-goals. This novel methodology has been tested in a study area in Iran to validate its added value in solving conflicting uses of natural resources by economic sectors. This integration together with its application for sustainable optimal cropping patterns (agroecosystem planning) represents a novelty in the field of ecological modeling. The management solutions of our method in terms of land allocation are different from those in Sen and Pal (2013) model. In the case of Iran, many socio-ecological-economic strategies and policies should be necessary for improving the agricultural sector. More specifically, on the basis of rainfall amounts and spatial patterns, this approach can represent a decision-support system able to define strategies for additional water storage useful to support crop production. Furthermore, the availability of water together with the sustainable use of fertilizers can mitigate the risk of land degradation, guaranteeing people employment, food security, and economic profits. Although the present methodology seems to solve the problem of multi-goals decision-making, the inclusion of spatial relationships is able to introduce dependencies between the management of land use in adjacent areas, making the present approach nearer to real-world functioning
