This research aims to produce nonwoven fabrics that can be used in car interior components (head liners, doors, side panels and trunk liners) to prevent noise from reaching the passenger compartment and therefore achieving comfort in the car interior. Two kinds of fibers were used, polyester and hollow polyester fibers, both of 6 denier, to produce three different fabrics of 100% polyester fibers, 75% polyester/25% hollow polyester fibers, and 55% polyester45% hollow polyester fibers. Four fabric weights were produced: 300, 400, 500 and 600 g/m². All samples were bonded using thermal bonding technique. More results were reached and most samples have achieved the expected results for example, samples produced with high percentage of hollow fibers have recorded the highest rates of sound absorption whereas samples produced with 100% polyester fibers have recorded the lowest rates. It was also found that there is a direct relationship between weight per m2 and sound absorption efficiency. Samples produced with 55% polyester/45% hollow polyester fibers and 600 g/m² have achieved the best results.

his research studies the effectiveness of different dialysis units on patients with renal failure by comparing the blood constituent before and after dialysis which indicates the dialyzer efficiency. Three kinds of hollow fiber materials were used in this research, Cuprophan, hemophan and polysulfone, with three surface areas of 1.1, 1.3, and 1.6 m². Different parameters were studied, including fiber type and surface area, to evaluate the efficiency of the dialyzers under study. Polysulfone dialyzers of 1.6 m² have achieved the best results compared to other types of dialyzers.

The purpose of this paper is to investigate leadership curricula in UAE business and education management programmes and examine the extent to which they are derived from and linked to students’ cultural and Islamic values using Habermas’ critical theory.

The study employs a mixed methods approach that takes classical pragmatism as its philosophical foundation and critical theory as a theoretical lens. Data are collected in four sequential phases using critical discourse analysis of course materials, class observations, student survey and faculty interviews. Results are integrated at the interpretative level and abductive reasoning is used as the logic of justification.

Results show that despite the increasing efforts to incorporate cultural and Islamic values into the curriculum, it is still mainly dominated by Western theories and models of leadership, especially in the leadership courses offered by business schools, mainly because of accreditation requirements and the lack of English resources and theories on UAE and Islamic models of leadership.

The study is limited to leadership curricula in the UAE. Researchers may extend and broaden the scope of the study by investigating leadership curricula in the Gulf and/or the Middle East. Future studies may also look at other theoretical frameworks recommended by other management scholars such as Mezirow’s transformational learning and the socio-constructivist approach (Hotho and Dowling, 2010). This study aims to open an ongoing debate and further investigation on the topic.

The results of the current study may inspire faculty members and programme coordinators to develop critical and culturally relevant curricula that are informed by Habermas’ critical theory and best teaching practices.

The study adds to the current knowledge base through its research design and approach that address an under-investigated topic. None of the current studies empirically investigated leadership curricula in the UAE. The theoretical framework and research findings can be used to develop culturally relevant and value-oriented leadership curricula that reflect indigenous and Western perspectives of leadership.

The purpose of this paper is to construct, for the first time, composite index for Egypt that measures the economic and social rights fulfillment (ESRF) based on socioeconomic surveys at the household/individual levels.

The paper highlights some of the statistical debatable issues about composite indices and focuses mainly on six of them. Those issues are indicators selection, handling missing data, identification of and dealing with outliers, scale of measurement, computing the margin of error, weights assigned for indicators and domains and aggregation method. Handling these problematic issues gave rise to a rigorous index.

The quality of economic and social rights fulfillment index (ESRFI) is judged by its bootstrap standard error. Based on these margin of errors, confidence intervals can be computed and rigorous comparisons across all disaggregation levels of the ESRFI can be made. The results shows that the overall index is accurate and representative in measuring the ESRF in Egypt. Comparisons between rural and urban regions indices show that the rural areas are always worse than the urban areas in all levels of dimensions, especially for the Right to Education and Adequate Housing.

The ESRFI is not very current because it is based on the 2010 Egyptian Household Conditions Observatory Survey (EHCOS), which is the latest published version of the survey with complete variables for the index data. When the next EHCOS becomes available, an updated ESRFI can be easily and quickly constructed.

The ESRFI could strengthen policy formulation that takes into account ESRF, especially by highlighting the situation in different regions and disaggregation levels.

The proposed ESRFI would strengthen policy formulation that takes into account ESRF, especially by highlighting the situation in different regions and different disaggregation levels.

The paper emphasizes the importance of recognizing and handling of the six problematic issues that arise when constructing composite indices. The paper presents the first ESRFI for Egypt and demonstrates the rigor of its construction.
