In this study, we conceptualize the thus far little explored relationship between expatriate and host country as a form of social exchange governed by the norm of reciprocity. Drawing from social exchange theory and our analysis of 451 self-initiated expatriates (SIEs) living and working in the United Arab Emirates, we examine whether the degree of SIEs’ career and community embeddedness explains their host country withdrawal intention via enhanced perceived institutional trust and a more tolerant attitude toward workplace discrimination. Our results provide general support for our theoretical model and most of our hypotheses. In this way, our article makes three contributions. First, it suggests a novel way to conceptualize the relationship between SIEs and host country as a form of social exchange. Second, it differentiates between two dimensions of embeddedness and explicates how the two contribute to SIEs’ intentions to stay in the host country. Finally, the analysis theorizes and empirically tests two previously little explored mechanisms of enhanced institutional trust and a more tolerant attitude toward workplace discrimination through which SIEs’ host country embeddedness influences their host country withdrawal intentions.

Camel milk has been consumed for centuries due to its medicinal and healing properties. The present study aims to investigate the consumption patterns of camel milk and perceived benefits and risks among adults in the United Arab Emirates. A self-administered online questionnaire was developed in English and Arabic languages and was completed online by 852 adults. Socio-demographic characteristics, camel milk consumption patterns and perceived knowledge of the benefits and risks of camel milk were investigated. About 60 % of the participants have tried drinking camel milk, but only a quarter (25⋅1 %) were regular consumers. The most consumed camel milk products after fresh milk were yoghurt and flavoured milk. The most popular additions to camel milk were honey, turmeric and sugar. Most consumers had less than one cup of camel milk per day (57⋅0 %). Camel milk consumers preferred it over other types of milk due to its nutritional value (66⋅4 %) and medicinal properties (39⋅3 %). Among consumers, 58⋅4 % reported consuming unpasteurised camel milk. Reasons included the belief that it is fresher (87⋅2 %), better for the immune system (41⋅6 %), and higher in nutrients (39⋅2 %). Overall, participants had inadequate knowledge about the health benefits of camel milk (7⋅11 ± 5⋅3 out of 25). Males and camel milk consumers had a significantly higher knowledge about the health benefits of camel milk compared to females and non-consumers (P < 0⋅05). Although positive perceptions were common, misperceptions appear to be prevalent among non-consumers. Consuming unpasteurised camel milk is a major public health concern, thus national regulations are essential.

During the first 1000 d of life, gestational weight gain (GWG) and postpartum weight retention (PPWR) are considered critical determinants of nutritional status. This study examined the effect of adherence to the Mediterranean diet (MD) during pregnancy on GWG and PPWR at 2 and 6 months among women in the United Arab Emirates (UAE), using data from the Mother-Infant Study Cohort. The latter is a prospective study, for which pregnant women were recruited (n 243) during their third trimester and were followed up for 18 months. Data on socio-demographic characteristics and anthropometric measurements were obtained. An eighty-six-item FFQ was used to examine dietary intake during pregnancy. Adherence to the MD was assessed using the alternate MD (aMED) and the Lebanese MD (LMD). Adherence to the MD, PPWR2 (2 months) and PPWR6 (6 months) were considered high if participants belonged to the third tertile of the respective measures. Results indicated that 57·5 % of participants had excessive GWG while 50·7 % and 45 % retained ≥ 5 kg at 2 and 6 months postpartum, respectively. After adjustment, adherence to both MD scores was associated with lower odds of excessive GWG (aMED, OR:0·41, 95 % CI:0·18, 0·93; LMD, OR:0·40, 95 % CI: 0·16, 0·98). Adherence to MD was also associated with PPWR2 (aMED: OR: 0·23, 95 % CI: 0·06, 0·88) and PPWR6 (aMED OR:0·26; 95 % CI:0·08–0·86; LMD, OR:0·32; 95 % CI: 0·1, 0·98). The findings of this study showed that adherence to the MD may reduce GWG and PPWR and, hence, underscored the importance of promoting the MD for better health of the mother and infant.

Serpentinization of ultramafic rocks in the sea and on land leads to the generation of alkaline fluids rich in molecular hydrogen (H2) and methane (CH4) that favour the formation of carbonate mineralization, such as veins in the sub-seafloor, seafloor carbonate chimneys and terrestrial hyperalkaline spring deposits. Examples of this type of seawater–rock interaction and the formation of serpentinization-derived carbonates in a shallow-marine environment are scarce, and almost entirely lacking in the geological record. Here we present evidence for serpentinization-induced fluid seepage in shallow-marine sedimentary rocks from the Upper Cretaceous (upper Campanian to lower Maastrichtian) Qahlah Formation at Jebel Huwayyah, United Arab Emirates. The research object is a metre-scale structure (the Jebel Huwayyah Mound) formed of calcite-cemented sand grains, which formed a positive seafloor feature. The Jebel Huwayyah Mound contains numerous vertically orientated fluid conduits containing two main phases of calcite cement. We use C and O stable isotopes and elemental composition to reconstruct the fluids from which these cements precipitated and infer that the fluids consisted of variable mixtures of seawater and fluids derived from serpentinization of the underlying Semail Ophiolite. Based on their negative δ13C values, hardgrounds in the same section as the Jebel Huwayyah Mound may also have had a similar origin. The Jebel Huwayyah Mound shows that serpentinization of the Semail Ophiolite by seawater occurred very soon after obduction and marine transgression, a process that continued through to the Miocene, and, with interaction of meteoric water, up to the present day.

The Islamic legal enterprise forms an inherently plural system that can appear puzzling to commentators looking for faithfulness to principle or precedent. When one looks at it, instead, as an ongoing search for correspondence between divine guidance, rooted in the foundational sources of Islam, and the singularity of concrete circumstances, Islamic law is revealed as a practice of discernment against the grain of the particular. This article unfolds this approach to understanding Islamic law by entering the conversation where it is currently most heated, namely in connection with the development of Islamic financial products. A case study of takāful regulation in the United Arab Emirates (UAE) helps substantiate the import of our proposal for attuning to the voice of Islamic jurisprudence (fiqh), in the face of contemporary questions arising from the design of financial products in correspondence with the Sharī’ah.

An understanding of the current state of mental health services in the United Arab Emirates (UAE) from a clinical perspective is an important step in advising government and stakeholders on addressing the mental health needs of the fast-growing population. We conducted a retrospective study of data on all patients admitted to a regional psychiatric in-patient unit between June 2012 and May 2015. More Emiratis (UAE nationals) were admitted compared with expatriates. Emiratis were diagnosed more frequently with substance use disorders and expatriates with stress-related conditions. Psychotic and bipolar disorders were the most common causes for admission and had the longest in-patient stays; advancing age was associated with longer duration of in-patient stay.

The present study assessed the associations of overweight, obesity and anaemia with selected lifestyle factors, total body fat and abdominal obesity among female university students in Dubai. A total of 251 female students from a national university in Dubai participated in the present study. Weight, height, waist circumference, Hb level and total body fat percentage were measured. Participants also completed a self-reported questionnaire that included items related to the factors of obesity, anaemia and lifestyle. The study was approved by the University Ethical Committee. Almost one-third of the participants were overweight/obese; 8⋅5 % had abdominal obesity while 18⋅1 % had anaemia. Out of the total, 71⋅7 % reported that they have irregular meals and the highest percentages were found among obese (89⋅3 %) and overweight (78⋅0 %) compared with normal-weight (65⋅4 %) students (P < 0⋅05). Overweight/obese students reported that they exercise more than those of normal weight (P = 0⋅05). Students with anaemia reported less exercise than students without anaemia (P = 0⋅05). Also, the percentage of total body fat was found to be the highest (38⋅9 %) among students with anaemia (P < 0⋅05). Overweight, obesity and anaemia are prevalent among female university students. Anaemia seems to be associated with the percentage of total body fat, lack of physical activity and junk food. Further studies are required to investigate the detailed dietary habits of overweight and obese young adult females with anaemia.

Oases are subject to decreasing resources and changing human activities. Fully aware of their rich heritage, the United Arab Emirates (UAE) have undertaken work to preserve and revitalize these oases. However, there is a clear lack of understanding of the dynamic links between climate change, hydraulic and agricultural management, and socioeconomic activities. To clarify these links, our team conducted a systematic geoarchaeological, geophysical, spatial, and chronological study of the Masafi oasis, UAE. Results indicate the existence of a natural humid area as early as the late Pleistocene (~18 cal ka BP). These conditions persist during the early-mid Holocene with drainage activation and soil development (~12–6.3 ka). During the late Holocene, after the emergence of the “artificial” oasis around ~3250 cal yr BP, cycles of intense management suggesting water availability (~3250–2380 cal yr BP; 550 cal yr BP) alternate with episodes of fluvial detritism (~2380–1870 cal yr BP; >550 cal yr BP) and scattered evidence of farming activities with complex hydroclimatic signatures (~2300–550 cal yr BP). These results, together with regional environmental data, indicate that water and soil resources were available and exploited strategically throughout the Holocene despite adverse climatic conditions, and the oasis of Masafi could have acted as a desert refugium.

We explore the impact of gender, individualism–collectivism on individual’s propensity to trust. The study draws on data from three groups of individuals in the United Arab Emirates: students; (n=370); small business owners/operators (n=324), and employed individuals (n=376). Three main hypotheses are tested. We develop and explore three main hypotheses. Statistical results reveal that females are generally more collectivist and less trusting than their males counterparts. Further analysis revealed that small business/operators are generally more trusting than the other cohorts of respondents. Propensity to trust was also found to be strongly associated with collectivist (rather than individualist) aspirations. Implications for future research and management practice are discussed.

Despite the wealth of archaeological sites and excellent conditions for preservation, few phytolith investigations have been undertaken from the Arabian Gulf region. The results from the Sasanian and Islamic archaeological tell of Kush, Ras al-Khaimah, United Arab Emirates, are presented. Kush is situated just inside the Gulf on an important trade route. The occupation sequence dates from the 4th century A.D. until the 13th century A.D., recording the development of the site in the Sasanian period, followed by the arrival of Islam in the 7th century A.D. and the final abandonment of the site in the late 13th century when the nearby site of al-Mataf (Julfar) began to develop closer to the present day coastline. All the samples analyzed contained abundant phytoliths (short cells, elongated cells, and groups of elongated cells) of various types. They included date palm (Phoenix dactylifera), papillae (possibly from barley (Hordeum)), and hair cells possibly from species of canary grass (Phalaris spp.). Some researchers have suggested that groups of elongated cells may indicate the presence of irrigation in semiarid environments. The present results for this class of phytoliths appeared to imply that intensive irrigation was unlikely to have taken place around Kush.
