Physical and geometrical parameters of the binary system gliese 150.2

The speckle interferometric binary system Gl 150.2 (HIP17491) is analyzed using atmosphere modeling and dynamical analysis simultaneously. A synthetic spectral energy distribution (SED) for each of the two components of the system is built using Kurucz blanketed models. These SEDs are combined together to form the total flux, which is compared with the observed one in an iterative method to get the best fit. The parameters of the individual components which lead to the best fit are: T eff A = 5350 ± 50 K, T eff B = 4400 ± 50 K, log g A = 4.40 ± 0.05, log g B = 4.68 ± 0.05, R A = 0.95 ± 0.06R ⊙, R B = 0.58 ± 0.06R ⊙, and π = 38.63 ± 0.79 mas, as given by the modified Hipparcos measurement. A modified orbit of the system is introduced and compared with earlier orbits. Hence, the masses of the two components are derived from the coincidence between the atmosphere modeling and dynamical analysis. Based on the estimated physical and geometrical parameters of the system, which are confirmed by synthetic photometry, the spectral types and luminosity classes of the two components are found to be G9.5V and K7V for the primary and secondary stars respectively, with an age of about 8 Gyr. Finally, the positions of both components on the H-R diagram are plotted, and the formation and evolution of the system are discussed. © 2014 Pleiades Publishing, Ltd

Civic Nationalism and Language-in-Education Policies in the United Arab Emirates

A founding principle of the United Arab Emirates is the belief that tolerance promotes peace, while isolation encourages division and conflict. With more than 200 nationalities residing in the UAE, Emiratis constitute only 10% of the population, making them a minority in their own country. Despite the government promoting diversity and tolerance as the norm, such demographic imbalance come with a cost to the Arabic language, the national identity and culture, and the education system. This chapter addresses those concerns through a series of recent government initiatives. The author classifies neo-nationalist movements into different types, arguing that the one in the UAE largely fits within the civic type with its non-hostile, overall welcoming attitude toward foreigners. At the end of the chapter, she discusses the impact of neo-nationalism on education and calls for clearer policies that take into account language(s) as a right and as a resource

The Experience of Quality in Higher Education in the United Arab Emirates: In Times of Rapid Change and Complexities

In less than five decades, from offering formal education only in a few schools to a small tribal community to providing a selection of three public and approximately 100 private higher education institutions to the citizens of seven emirates creates a unique context in the United Arab Emirates (UAE). It is an evolution that corresponds with its remarkable economic growth. Quality assurance of diverse higher educational institutions requires complex schemes to ensure their fitness for purpose, while perhaps development and enhancement aspects need time to mature. The quality of the education is especially important because the UAE yearns for the diversified and knowledge-based economy; one that is led by its own citizens whose contribution to the workforce is currently less than 10%. This chapter highlights contextual complexities in the UAE that might have direct and/or indirect impacts on the quality experiences in the higher education sector, with proposed recommendations

The state of HRM in the Middle East:Challenges and future research agenda

Based on a robust structured literature analysis, this paper highlights the key developments in the field of human resource management (HRM) in the Middle East. Utilizing the institutional perspective, the analysis contributes to the literature on HRM in the Middle East by focusing on four key themes. First, it highlights the topical need to analyze the context-specific nature of HRM in the region. Second, via the adoption of a systematic review, it highlights state of development in HRM in the research analysis set-up. Third, the analysis also helps to reveal the challenges facing the HRM function in the Middle East. Fourth, it presents an agenda for future research in the form of research directions. While doing the above, it revisits the notions of “universalistic” and “best practice” HRM (convergence) versus “best-fit” or context distinctive (divergence) and also alternate models/diffusion of HRM (crossvergence) in the Middle Eastern context. The analysis, based on the framework of cross-national HRM comparisons, helps to make both theoretical and practical implications

Bringing it all back home: the HRM role in workforce localisation in MNEs in Saudi Arabia

Governments across the Arabian Gulf aim to reduce their dependence on expatriates by implementing localisation policies. Building on institutional and legitimacy theories, we seek to advance our understanding of the effects of such policies on multinational enterprises (MNEs). We used data from 157 MNEs operating in Saudi Arabia and found the indigenisation of the HRM function is closely correlated with the level of workforce localisation: key factors empowering localisation, defined as recruitment and training practices geared towards the needs of locals, include the demographics and role of the HRM Director. Theoretically, we contribute to the literature on institutionalism and legitimacy by revealing how various institutional forces influence the process of selection and transfer of HRM practices to adapt to the institutional environment of a given context. Our research also shows that if MNEs follow government recommendations, develop links with local educational institutions to target suitable job candidates, and adapt to shortages in local skills and competencies by investing in the training and development of local workers, they will be more likely to achieve success in workforce localisation and legitimacy

Infantile Extracranial Rhabdoid Tumor of the Scalp

Extracranial rhabdoid tumor is a rare tumor that can originate in multiple organs, and it is most commonly seen in the kidneys. This tumor has a grave prognosis. We report to the best of our knowledge the first case of infantile scalp extracranial rhabdoid tumor in a 6-month-old male baby who presented with a right parietal scalp mass since the age of 1 month. This mass was initially diagnosed as scalp hemangioma based on clinical and imaging findings. However, this mass was growing fast which necessitated excision. Pathologic examination after excision showed a malignant tumor composed of sheets of rhabdoid cells. Immunohistochemically, this tumor tested positive for vimentin, CD 99, glypican-3, synaptopysin, WT-1, CK, and EMA. INI-1 immunostain was lost in the tumor cells. Subsequently, this tumor was pathologically diagnosed as extracranial scalp rhabdoid tumor. After tumor excision, the patient was referred to pediatric oncology to receive chemotherapy. Experience with scalp extracranial rhabdoid tumors is limited. However, this tumor in other organs carries a grave prognosis. Although scalp extracranial rhabdoid tumor is an extremely rare tumor, it should be kept in mind in the differential diagnosis of infantile scalp masses given the need of combined surgical and chemotherapeutic treatment
