Talent management in Covid -19 crisis â how Dubai manages and sustains its global talent pool
Taking stock is a difficult task to get right, particularly in a world where future outlooks are changing all around us, shifting the landscape on which we stand. Predictably, policy makers and business leaders feel anxious as they struggle to marshal and mobilize their talent pool through this global health crisis. Unlike other global crises, this exogenous shock has speeded up the adoption of social and physical distance and remote working and may be pointing the way to the future of global talent management. The increased IT capacity and a move away from traditional work arrangements make talent more mobile, which means cities and business compete for the best employees globally. This is in particular true for geographic locations in which demographic trends drive talent shortage, such as in Dubai
Perceived Training Opportunities and Knowledge Sharing: The case of the United Arab Emirates
We seek to explore the interplay between perceived training opportunities (PTOs) and knowledge sharing in the context of the emerging economic setting of the United Arab Emirates. We also examined the moderating role of intrinsic and extrinsic motivation and engagement in social interaction on the relationship between PTOs and knowledge sharing. The study employed a survey method to collect the data, and tested the proposed hypotheses by using the partial structural equation modelling (PLS-SEM) technique. Data is based on 815 responses across all sectors in the country context of the UAE. Our findings indicate that PTOs are positively related to knowledge sharing. Notably, the results show that the proposed relationship between PTOs and knowledge sharing is negatively and significantly moderated by intrinsic motivation. Moreover, the moderating role of extrinsic motivation and engagement in social interaction were insignificant. At a theoretical level, this article provides an individual level analysis, which indicates that PTOs pave the way for intraorganizational knowledge sharing; hence, they offer insights into the mechanisms in which PTOs impact on knowledge sharing. This article also contributes to our general understanding on human resource management (HRM) practices and knowledge sharing in the context of the emerging economy of the UAE; the latter has a number of implications for both, theory and practice as delineated in this study
Population history from the Neolithic to present on the Mediterranean island of Sardinia: an ancient DNA perspective
Recent ancient DNA studies of western Eurasia have revealed a dynamic history of admixture, with evidence for major migrations during the Neolithic and Bronze Age. The population of the Mediterranean island of Sardinia has been notable in these studies â} Neolithic individuals from mainland Europe cluster more closely with Sardinian individuals than with all other present-day Europeans. The current model to explain this result is that Sardinia received an initial influx of Neolithic ancestry and then remained relatively isolated from expansions in the later Neolithic and Bronze Age that took place in continental Europe. To test this model, we generated genome-wide capture data (approximately 1.2 million variants) for 43 ancient Sardinian individuals spanning the Neolithic through the Bronze Age, including individuals from Sardinia{â}s Nuragic culture, which is known for the construction of numerous large stone towers throughout the island. We analyze these new samples in the context of previously generated genome-wide ancient DNA data from 972 ancient individuals across western Eurasia and whole-genome sequence data from approximately 1,500 modern individuals from Sardinia. The ancient Sardinian individuals show a strong affinity to western Mediterranean Neolithic populations and we infer a high degree of genetic continuity on the island from the Neolithic (around fifth millennium BCE) through the Nuragic period (second millennium BCE). In particular, during the Bronze Age in Sardinia, we do not find significant levels of the {â}Steppe{â ancestry that was spreading in many other parts of Europe at that time. We also characterize subsequent genetic influx between the Nuragic period and the present. We detect novel, modest signals of admixture between 1,000 BCE and present-day, from ancestry sources in the eastern and northern Mediterranean. Within Sardinia, we confirm that populations from the more geographically isolated mountainous provinces have experienced elevated levels of genetic drift and that northern and southwestern regions of the island received more gene flow from outside Sardinia. Overall, our genetic analysis sheds new light on the origin of Neolithic settlement on Sardinia, reinforces models of genetic continuity on the island, and provides enhanced power to detect post-Bronze-Age gene flow. Together, these findings offer a refined demographic model for future medical genetic studies in Sardinia
Unveiling Dubai's knowledge economy: a journey towards enhancing knowledge exchange and human capital
Purpose: The purpose of this study is to investigate the factors that influence the development of human capital by examining the interplay between different organizational mechanisms, including leadership, organizational culture, and HRM practices. This study aims to enhance our understanding of how knowledge exchange influences human capital, with a specific focus on the unique context of Dubai, an area and context that have been underexplored in this research domain.
Design/Methodology/Approach: This study employed a survey-based approach, involving 611 participants working across different sectors based in Dubai. We used partial least squares structural equation modelling (PLS-SEM) as the statistical analysis method.
Findings: The results of the study indicate that leadership behaviours have a predictive influence on organizational culture. In turn, organizational culture significantly affects knowledge exchange. Additionally, the study reveals that commitment-based HRM practices play a significant moderating role in the relationship between organizational culture and knowledge exchange.
Originality: This study contributes to the existing literature by providing valuable insights into the interplay between leadership, organizational culture, and commitment-based HRM practices. By exploring these factors and their influence on knowledge exchange and human capital, the study enhances both the theoretical understanding and practical application in this field.
Implications: The findings of this study have important implications for organizations in Dubai and beyond. Understanding the relationships between leadership, organizational culture, commitment-based HRM practices, and knowledge exchange can help organizations develop strategies to enhance their human capital. By fostering a positive organizational culture, implementing effective leadership practices, and adopting commitment-based HRM practices, organizations can promote knowledge exchange and ultimately improve their human capital development.

Iron Age and Anglo-Saxon genomes from East England reveal British migration history
British population history has been shaped by a series of immigrations, including the early Anglo-Saxon migrations after 400 CE. It remains an open question how these events affected the genetic composition of the current British population. Here, we present whole-genome sequences from 10 individuals excavated close to Cambridge in the East of England, ranging from the late Iron Age to the middle Anglo-Saxon period. By analysing shared rare variants with hundreds of modern samples from Britain and Europe, we estimate that on average the contemporary East English population derives 38% of its ancestry from Anglo-Saxon migrations. We gain further insight with a new method, rarecoal, which infers population history and identifies fine-scale genetic ancestry from rare variants. Using rarecoal we find that the Anglo-Saxon samples are closely related to modern Dutch and Danish populations, while the Iron Age samples share ancestors with multiple Northern European populations including Britain
Mitochondrial DNA signals of late glacial recolonization of Europe from near Eastern refugia
Human populations, along with those of many other species, are thought to have contracted into a number of refuge areas at the height of the last Ice Age. European populations are believed to be, to a large extent, the descendants of the inhabitants of these refugia, and some extant mtDNA lineages can be traced to refugia in Franco-Cantabria (haplogroups H1, H3, V, and U5b1), the Italian Peninsula (U5b3), and the East European Plain (U4 and U5a). Parts of the Near East, such as the Levant, were also continuously inhabited throughout the Last Glacial Maximum, but unlike western and eastern Europe, no archaeological or genetic evidence for Late Glacial expansions into Europe from the Near East has hitherto been discovered. Here we report, on the basis of an enlarged whole-genome mitochondrial database, that a substantial, perhaps predominant, signal from mitochondrial haplogroups J and T, previously thought to have spread primarily from the Near East into Europe with the Neolithic population, may in fact reflect dispersals during the Late Glacial period, ?19â12 thousand years (ka) ago.<br/
Causes and risk factors for common mental illnesses : the beliefs of paediatric hospital staff in the United Arab Emirates
Background
Children and adolescents with chronic physical health conditions are vulnerable to poor mental health outcomes. The measurement of mental health literacy of health professionals working with such populations is important because of their role in promoting early and appropriate help-seeking. This study sought to determine the beliefs regarding the causes of and risks factors for three types of mental illnesses amongst health professionals in United Arab Emirates.
Method
A culturally validated mental health literacy survey presenting three vignettes of fictional characters meeting diagnostic criteria for posttraumatic stress disorder, depression with suicidal thoughts and psychosis was distributed. The survey measured health care professionalsâ beliefs regarding the causes of and risk factors for these disorders.
Results
A total of 317 health care professional (>â90% nurses) were surveyed from across the UAE. Although 43.8% correctly endorsed exposure to a âtraumatic eventâ as the most likely cause for developing posttraumatic stress disorder, there was a more limited understanding of the contribution of biopsychosocial factors to the development of the mental illness, particularly for psychosis. Participant socio-demographic variables were associated with attributions of religious or spiritual beliefs and personal weakness as causal and/or vulnerability factors in the development of depression with suicidal thoughts and psychosis.
Conclusions
Efforts to improve mental health systems and health care providers in UAE and other similar Middle Eastern countries requires targeted mental health literacy programs that seek to integrate biopsychosocial models of mental illness and their treatment with the positive aspects of religious and cultural beliefs that are dominant in this region

'Hidden' expatriates: international mobility in the United Arab Emirates as a challenge to current understanding of expatriation
Expatriates are often assumed to have enhanced terms and conditions and, because that makes them expensive, to be in key managerial or technical specialist roles. Employees who come from abroad and are in more manual or even menial roles are usually referred to as âmigrantsâ. However, there are millions of people around the world who are not migrants, their intended sojourn in a foreign country is seen by them and their employers as temporary, but their employment contracts are far from advantageous compared with those of locals. These âhiddenâ expatriates are brought into focus in the emerging Arab Gulf States. In some of these countries, the population consists mainly of expatriates, with the local population a small minority: These expatriates include many in lower-management or manual or menial jobs. We demarcate these expatriates from organisationally assigned expatriates, self-initiated expatriates and migrants. We use qualitative data from such expatriates in the United Arab Emirates to explore the issues this raises for governments, employers and the expatriates â and for our understanding of the phenomenon of expatriation
Biallelic loss of LDB3 leads to a lethal pediatric dilated cardiomyopathy
Autosomal dominant variants in LDB3 (also known as ZASP), encoding the PDZ-LIM domain-binding factor, have been linked to a late onset phenotype of cardiomyopathy and myofibrillar myopathy in humans. However, despite knockout mice displaying a much more severe phenotype with premature death, bi-allelic variants in LDB3 have not yet been reported. Here we identify biallelic loss-of-function variants in five unrelated cardiomyopathy families by next-generation sequencing. In the first family, we identified compound heterozygous LOF variants in LDB3 in a fetus with bilateral talipes and mild left cardiac ventricular enlargement. Ultra-structural examination revealed highly irregular Z-disc formation, and RNA analysis demonstrated little/no expression of LDB3 protein with a functional C-terminal LIM domain in muscle tissue from the affected fetus. In a second family, a homozygous LDB3 nonsense variant was identified in a young girl with severe early-onset dilated cardiomyopathy with left ventricular non-compaction; the same homozygous nonsense variant was identified in a third unrelated female infant with dilated cardiomyopathy. We further identified homozygous LDB3 frameshift variants in two unrelated probands diagnosed with cardiomegaly and severely reduced left ventricular ejection fraction. Our findings demonstrate that recessive LDB3 variants can lead to an early-onset severe human phenotype of cardiomyopathy and myopathy, reminiscent of the knockout mouse phenotype, and supporting a loss of function mechanism
