Background and objectives Allergic rhinitis is a morbid condition that is frequently overlooked by patients and physicians. This type of atopy has not been adequately investigated in the United Arab Emirates.Methods This cross-sectional, population-based observational study was conducted in the seven Emirates (Abu Dhabi, Dubai, Sharjah, Ajman, Umm Al-Quwain, Ras Al-Khaimah, and Fujairah). It used the European Community Respiratory Health Survey (ECRHS II) to screen for allergic rhinitis in people living in this region.Results Symptoms of allergic rhinitis were present in 85 (7%) of the 1,229 study population. Only 33 (39%) patients received treatment. Seventy-six (89%) patients had asthma. Thirty-seven (44%) patients were poly-sensitized. Symptoms were aggravated by dust (59%), grass/pollens (44%) and proximity to animals (21%). Winter was the peak season (37%), followed by spring (30%), autumn (18%) and summer (15%). Grass/pollen allergies were clustered in the winter, spring and summer (p ≤ 0.001). Dust was non-seasonal (p ≥ 0.121) and animal allergy was worse in the winter (p = 0.024) and spring (p = 0.044). Spring symptoms were less common in people living in the inner city (p = 0.003).Conclusions At least 7% of the studied population had allergic rhinitis. Most (71%) of these patients had environmental triggers and remained untreated. Allergic rhinitis awareness and measures to control allergens and dust are needed. The impact of preventing allergic rhinitis on other common atopies in the region deserves future studies.

This paper analyses the importance of 'Shari'a scholars' in the Islamic Financial Services (IFS) sector, which has been a growing global practice since the 1970s. Based on Shari'a Law, IFS firms provide banking, finance and insurance respecting faith-based prohibitions on interest, speculation and risk taking. Although IFS firms operate across a variety of scales and involve a range of actors, this paper focuses on the transnational capacities of Shari'a experts employed by IFS firms. These scholars use their extensive knowledge of Shari'a Law to assess the 'Islamic' character of a firm's operations, and assist the development of Shari'a-compliant products. As they embody necessary entry-points into Islamic circuits of knowledge and authority, members of what we dub the 'global Shari'a elite' can be regarded as 'gatekeepers' of Islamic financial circuits. Drawing on a comprehensive data source we present a geographical analysis of Shari'a board membership, nationality and educational background of 253 Shari'a scholars. The results show that the global Shari'a elite connects a limited number of IFS hubs (e. g. Dubai, Kuala Lumpur, Kuwait City, Manama, and London) to knowledge and authority networks falling outside 'mainstream' business and service spheres.

- Abstract
Recently, the way we learn has been shifted dramatically from traditional classrooms relying on printed papers into E-learning relying on digital/electronic pages. Modern educational technologies attempt to facilitate the delivery of learning from instructors to students in a more flexible and comfortable way. Mobile learning (M-learning) is one of such ubiquitous technologies that has been evolved rapidly to deliver E-learning using personal electronic devices without posing any restrictions on time and location. A review of the state-of-the-art of M-learning regarding the students’ and faculty members’ attitudes towards the use and adoption of M-learning in the higher educational environments worldwide is addressed. We observed that M-learning has not yet been studied intensively within the Gulf Region universities; the reason that motivated us to focus our study on this area and attempt to identify the gaps that have not been covered within the current available research. Understanding students and faculty members’ attitudes within Gulf region countries is the first step towards applying M-learning. Two questionnaires surveys within two neighboring countries within the Gulf region (Oman & UAE) have been conducted in order to examine both students and faculty members’ attitudes towards the use of M-learning in the higher education environments. Data was collected from five universities in the Gulf region, one from Oman and four from UAE. 383 students and 54 instructors took part within the study. Findings give a strong indicator that M-learning can be one of the promising educational technologies to be implemented in the higher educational environments within the Gulf region countries.

The relatively short social and economic history of the urban Gulf has undergone radical evolutions over recent years. Cities in the Gulf have advanced on investing in holistic urban planning and branding strategies. The majority of these investments were not merely intent on supplying various infrastructures for local communities, but more importantly aimed at foreign influx, through tourism and attracting foreign businesses with the possibility to set-up regional offices and increase revenues. Important in this is both the hardware (city planning) and software (city marketing). In recent years, major cities - such as Dubai, Abu Dhabi and Doha - have been confronted with providing a strong and profitable infrastructure for their respective tourist/business industries. This brings to light some new dilemmas to be answered, which include the following: 1. Space vs. time 2. Short term vs. long term 3. Planning vs. marketing 4. Infrastructure vs. network 5. Global vs. local ‚Üí glocal 6. Work vs. leisure 7. Economy vs. culture & society 8. Traditional marketing vs. alternative marketing The paper then discusses the new approaches linking city planning with city marketing, like time planning, leisure (cultural, tourism, sports, entertainment) planning, social town planning (incorporating the previous two), creative cities, urban regeneration, strategic planning, collaborative planning, urban management, Public Private Partnerships and the representation of the city in cinema. Then an attempt is made to answer questions like the influence that the temporary nature of many of the residents/expats of the Gulf cities have on their future composition, the social implications of the rapid economic growth, the kind of projects that are revealed when considering the reassessment of the social/economic infrastructure within these cities etc., before ending with the conclusions about the necessity of a strategic urban development plan especially for cities with a strong infrastructure for tourism & business, incorporating: City marketing plan involving the cooperation of tourists, businesses & residents (focus on the quest for local identity) Leisure plan (combining tourism, culture, sports & entertainment) Time master plan

In the last few years, the way we learn has been shifted dramatically from traditional classrooms depending on printed papers into E-learning depending on digital pages. Mobile learning (M-learning) is a recent technology that has been developed rapidly to deliver E-learning using personal mobile devices without posing any restrictions on time and location. In this work, we investigate students and faculty members’ attitudes towards the use of M-learning in higher educational institutions within two countries in the Gulf Region (Oman & UAE). Two questionnaire surveys have been conducted: one for students and another for faculty members. In these surveys, 383 students and 54 instructors have taken part within the study. An independent sample t-test was performed to examine whether there exist a significant difference among the students’ attitudes and the faculty members’ attitudes towards the use of M-learning with regard to gender and country. Results indicated that students in the UAE were more positive towards the use of M-learning than those in Oman. Moreover, results revealed that 99% of the students own mobile devices, in particular smartphones and tablets, while only 1% has not. Results of this study could help policy makers for better decision making in building the M-learning infrastructure in the higher educational institutions in general and specifically within the Arab Gulf region.

American women academicians ,Gulf region ,Arab count - Abstract
In the 21st century, more and more American women educators are going overseas to work, often to developing countries (Elfenbein, Lucas, Ewell, Cirksena, & McFadden, 1998). However, few studies have been conducted about working abroad (Osland, 1995), and even fewer studies examine academics (Razzano, 1994), particularly women professionals who have worked overseas (Lyon, 2001). A review of the literature revealed that almost no studies have been conducted that focus on American women faculty and administrators working in higher education in the Arab countries. This study provides information not currently available, and the findings are a valuable resource of information about the nature of life and the professional environment in Arabic countries. The information will help women educators, especially those who are interested in working in the Arab countries. This research is structured around two themes: (a) cross-cultural adaptation, and (b) globalization. The study attempts to place American women academicians and higher education within the global context by: (a) exploring the cultural adaptation of American women faculty and administrators who worked at a university in the Arab countries of the Gulf region, (b) investigating how these American women academicians have contributed to globalization of higher education abroad and in the United States, and (c) describing experiences of working abroad in order to help women academicians in the U.S. who are considering an opportunity to work at a university in the Arab countries. This qualitative research used a case study design. Seven women faculty and administrators in this study were personally interviewed by the researcher. The philosophical lens selected for the analysis was phenomenology. During data analysis, events and incidents described by participants that were potentially indicative and supportive of key issues were compared and verified across the data. Key issues were then categorized, conceptualized, and provisionally labeled. Issues that appeared to relate across various categories were grouped and given a conceptual name. From the discussion of 17 fundamental themes under six categories of findings of this study conclusions were drawn. Implications for the development of theory and practice in the cross-cultural adaptation of people in academia and globalization and internationalization of higher education were provided. Additionally, recommendations for Arab universities and future research were made.

This article argues that in the Gulf, contrary to other regions of the world, the necessity to control mass migrations preceded the official establishment of definitive borders and state structures. It then shows that this very sequencing, compounded with the issue of oil revenues' distribution, affected the forms of movement control that were opted for, as well as the types of nationality issues that derived from it.

The present paper scrutinizes the extant literature on the internationalization process of service providers. It provides an overview of current insights and unresolved issues. The findings of over 100 published studies are structured and summarized under four headings: internationalization motives, country/market selection, entry mode choice, and the profile of service exporters. Although literature is closing the gap with reality, this paper concludes that (empirical) work still lacks sound theoretical bases, and - partially as a consequence - it is largely fragmented and exploratory. Per heading we formulate specific suggestion for better and more focused future research endeavors. © 2005 Elsevier Ltd. All rights reserved.

- Abstract
Postoperative pain is a considerable issue in the Gulf region; however, at present there is a lack of comprehensive guidelines addressing postoperative pain management in the region. Therefore, an expert panel of pain specialists convened to address this issue and a set of key recommendations has been developed pertinent to the practice of postoperative pain management in the Gulf region (Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates and Yemen). These recommendations take into consideration the unique variation in cultural, religious and societal beliefs found in the region, as well as varying accessibility to pain medications, thereby aiming to serve as evidence-based guidance on the best practice management of postoperative pain in the Gulf region.

- Abstract
Sedimentation, growth fault slip, and shelf-margin progradation rates were determined for a transect of Tertiary sediments along the axis of the San Marcos arch in the northwestern Gulf of Mexico basin. This low relief area was the site of shorezone depositional systems throughout most of the Tertiary and has not been affected by salt mobilization or the sedimentological overprint of large delta systems. Consequently, rates calculated in the area represent average rather than extreme values. Detailed correlation of 142 well logs and the utilization of paleontologic data from 17 wells made possible the construction of a chronostratigraphic cross section which divided the Tertiary section into 1 or 2 million year increments. A decompaction computer program, which utilizes published compaction curves and distinguishes between normally pressured shale, underconsolidated overpressured shale, and sandstone, calculated original sediment thickness and sedimentation rates for each of the chronostratigraphic layers. Regional sedimentation rates varied almost two orders of magnitude during the Tertiary. These findings seriously challenge the common assumption of relatively uniform sediment supply over geological time spans. Within individual chronostratigraphic layers, sedimentation rates ranged from 4 cm/1000 yrs in the fluvial and transgressive facies to 130 cm/1000 yrs in the lower Miocene outer shelf and slope facies. Decompaction of the section also allowed the calculation of growth fault slip rates and of the percent increase in accommodation on the downthrown side of the faults relative to their upthrown equivalents. Slip rates during times of maximum movement ranged from 250-600 m/my, agreeing with rates calculated for salt dome growth. Percent increase in accommodation on the downthrown side of the faults ranged from 20-83%. Shelf-margin progradation rates were calculated and ranged from -1.5 mi/my (2.4 km/my) during brief times of temporary retrogradation (Queen City and Yegua Formations) to 17.5 mi/my (28.2 km/my) during the Early Miocene

- Abstract
The Upper Wilcox genetic sequence (UWGS) is a transgressively bounded unit that represents the last major progradational episode associated with Wilcox (Paleocene-Eocene) deposition in the Texas Gulf Coast basin. The UWGS includes at outcrop, the Sabinetown Formation, the Carrizo Formation and the lower Reklaw Formation, and in the subsurface it includes the upper part of the Middle Wilcox Subgroup, all of the Upper Wilcox Subgroup and the lower part of the Reklaw Formation. UWGS depositional systems in the Rio Grande embayment (South Texas) include two large but distinct delta complexes, the Rosita and Burgos deltas. The Rosita delta system contains the Duval, Massive, and Live Oak deltas which were fed by the Carrizo fluvial system. The Burgos delta system contains the Fandango and the Zapata deltas and was fed by an unnamed and unmapped fluvial system originating from northern Mexico. Depositional systems within the UWGS in the Houston embayment (East Texas) include two small delta systems, the Columbus and the Jasper, and an intervening strandplain system, the Harris. The Columbus delta was supplied by the Jewett fluvial system and the Jasper delta by an unnamed and unmapped fluvial system originating in Louisiana. UWGS deposition began following the transgression of the Lower Wilcox shelf margin and the deposition of a regional marine mudstone containing a maximum flooding surface (MFS). An influx of sediment from the west from the last pulse of the Laramide Orogeny (55ma) began deltaic progradation in the Rio Grande embayment. At approximately the same time, delta systems in the Houston embayment first prograded and then were transgressed as the trunk fluvial system shifted to the southwest. The resulting transgressive deposits include the Yoakum shale, which defines the top of the Sabinetown Formation. A fall in sea level at the end of the Yoakum/Sabinetown transgression extended the delta systems in the Rio Grande embayment to the shelf edge; the smaller delta systems in the Houston embayment shifted basinward. A slow relative rise followed as the systems in both embayments continued to prograde/aggrade and then were progressively transgressed. A transgressive shelf with isolated sands ('Atkinson' sands) developed over the drowned basin margin. The Bigford barrier/lagoon complex marked the maximum landward migration of the shoreline

- Abstract
Deposition on the Texas coastal plain and shelf during the last Pleistocene glacial cycle has been interpreted from topographic and bathymetric maps, from borehole data including results of a detailed drilling study in Brazoria County, and from offshore sparker-profiles. The stratigraphic unit deposited during the last glacial cycle is bounded above by a largely undissected topographic surface (Beaumont), and below by a buried paleosol of stiff gray clay that correlates offshore with a persistent seismic reflector. The lower Texas coastal plain is essentially a clay-rich alluvial plain made up of coalescing low-gradient fans. The Beaumont alluvial plain onlaps an older surface (Lissie) which was tilted seaward prior to Beaumont deposition; the Lissie in turn onlaps remnants of older surfaces. During Beaumont deposition, each major coastal river deposited a branching network of meanderbelt sand-bodies by repeated avulsions. Borehole data for a meanderbelt of the ancestral Brazos River indicate that the channel was 5 to 7 m deep but that substantially greater sand thicknesses developed by stacking of point-bar sequences during fluvial aggradation. Downdip transition of fluvial deposits into deltaic and paralic sediments is inferred from shell beds, strike-oriented sand bodies, beach ridges, changes in clay color, and clinoform reflectors on sparker profiles. The updip limit of marine influence is delineated by the distribution of shell beds; the downdip limit of deltaic pro gradation is indicated by a paleobathymetric break in slope. Strike-oriented sands (Ingleside), including barrier islands and strandplains, developed contemporaneously with Beaumont fluvial aggradation. Sand thicknesses and multiple levels of sand suggest that beach-shoreface sequences are multistoried, similar to the fluvial sands. The thickest and widest strike sands formed in bights between the larger, more prominent deltaic systems. In response to falling sea level, deltas prograded from the Ingleside shoreline to the shelf edge. Sparker profiles show that deltaic thicknesses and offshore slopes increased gradually during progradation, then rapidly near the shelf edge, where deltaic sequences became stacked or imbricated. Major growth faulting and salt flowage near the shelf break were associated with the thickest deposits. Between the large Colorado and Rio Grande delta systems, reefs grew near the shelf edge. Late Pleistocene sea-level fluctuations resulted in three depositional phases: an aggradational phase (ca. 120,000 B.P.) during late rise and stillstand, dominated by fluvial and strike systems; a progradational phase (100,000 to 20,000 B.P.) during a gradual fall, dominated by deltaic systems, and a rapid transgressive phase (20,000 to 4000 B.P.). The Texas coast is now in another aggradational phase. Average rates of late Pleistocene sediment influx were similar to historic rates, and show a decrease in sediment production toward the arid southwest. Post-depositional deformation of the Beaumont and Lissie alluvial plains and Ingleside shoreline can be explained largely as an isostatic response to sedimentary loading

- Abstract
The Stuart City Trend in south Texas is a Lower Cretaceous shelf-edge buildup of bioclastic and reefal carbonates. This carbonate system is currently buried to depths of between 3,300 and 5,000 meters. Combined with the equivalent updip shallow water, shelf carbonates of the Edwards and Glen Rose Formations, these carbonates form an extensive Gulfward dipping carbonate wedge. The whole-rock chemical and isotopic characteristics of the limestones of the Stuart City are the product of their initial composition and early surface and near-surface diagenetic history. Burial diagenesis has not significantly altered the chemical and isotopic character of these limestones. Marine diagenesis was volumetrically important and consisted of micritization and the precipitation of fine to very coarsely crystalline, fibrous to bladed, isopachous, Mg-calcite cements. These cements have been neomorphically altered to calcite, while still retaining a Mg⁺⁺ memory and a marine-like isotopic character. Diagenesis by meteoric water was volumetrically important in altering the depositional character of the carbonate sediments associated with the topographic highs along the Stuart City Trend. Secondary porosity formation, Mg-calcite and aragonite stabilization and equant spar calcite cementation are important products of this diagenesis. The equant spar calcite cements are poor in iron and manganese. They make up approximately 16 percent by volume of the limestones studied. The majority of these cements have δ¹³C compositions which fall in the range of modern marine carbonates [...]. Oxygen isotopic variability of the equant spar calcites is controlled by the δ¹⁸O composition of the diagenetic fluids and the degree of openness of the carbonate sediments to these fluids. Thermally induced ¹⁸O depletion in the equant spar calcites was of secondary importance. Pyrobitumen pore fillings and inclusions in the outer one millimeter rims of the very coarsely crystalline, equant spar calcite cements indicate that only minor amounts of calcite cementation have occurred since hydrocarbon migration. These hydrocarbons are believed to have originated from Jurassic and Cretaceous source rocks. Deep burial diagenesis, i.e., post hydrocarbon migration, consisted of the precipitation of minor amounts of galena, fluorite and Sr⁺⁺-rich equant spar calcites. These diagenetic events can be directly related to the chemistry of present-day formation waters. The densities of sodium-calcium-chloride brines of the Edwards Formation and of the Stuart City Trend range from 1.018 grams per cm³ in the shallow, updip hydrocarbon fields to more than 1.21 grams per cm³ in the deepest hydrocarbon fields. The oxygen isotopic composition of the formation waters becomes increasingly enriched in ¹⁸O with increasing depth. Interaction of the formation waters with the carbonate country rock at elevated temperatures is responsible for this enrichment trend. The Mg⁺⁺/Ca⁺⁺ ratio of the formation waters increases with decreasing depth. Dedolomitization and dolomite dissolution are the major diagenetic processes responsible for Mg⁺⁺ enrichment. Movement of deeper basinal waters, potentially of Jurassic origin, into the Stuart City Trend and Edwards Formation is occurring via major faults

This paper analyses the importance of 'Shari'a scholars' in the Islamic Financial Services (IFS) sector, which has been a growing global practice since the 1970s. Based on Shari'a Law, IFS firms provide banking, finance and insurance respecting faith-based prohibitions on interest, speculation and risk taking. Although IFS firms operate across a variety of scales and involve a range of actors, this paper focuses on the transnational capacities of Shari'a experts employed by IFS firms. These scholars use their extensive knowledge of Shari'a Law to assess the 'Islamic' character of a firm's operations, and assist the development of Shari'a-compliant products.
