Strategic Leadership Practices in hotels, An applied study of Algerian hotels group

هدفت الدراسة إلى تشخيص وتقييم ممارسات القيادة الإستراتيجية السائدة في الفنادق الجزائرية حيث تم تبني أربعة ممارسات لـ:Hitt& all, (2001). وقد تم الاعتماد على الاستبانة كأداة أساسية لجمع البيانات الأولية من عينة عشوائية بسيطة لموظفي الفنادق الجزائرية بلغ حجمها 343 موظف من 15 فندق في 8 ولايات  بكل من شمال، جنوب، شرق، وغرب الجزائر. كما تم إجراء مجموعة مقابلات مع ممثل لمؤسسة التسيير السياحي في ولاية بسكرة من أجل دعم تفسير النتائج. وقد أكدت نتائج الدراسة أن كل من الممارسات القيادية المرتبطة برأس المال البشري، الممارسات القيادية المرتبطة بالثقافة التنظيمية، والممارسات القيادية المرتبطة بالرقابة المتوازنة كانت مرتفعة، في حين الممارسات القيادية المرتبطة بالتصور الإستراتيجي المستقبلي كانت متوسطة. كما وجدت فيه فروق دالة إحصائيا حول ممارسات القيادة الإستراتيجية في الفنادق تعزى لكل من الجنس والعمر. وقدمت الدراسة مجموعة من التفسيرات والتوصيات ذات الصلة بالموضوع.The Current Study aimed to evaluate the Strategic Leadership Practices prevailing in Algerian hotels, where four practices of the researcher Hitt& all, (2001).  The questionnaire was used as a tool to gather the primary data from a simple random sample of 343 employees of Algerian hotels from 15 hotels in 8 states in North, South, East and West Algeria, and the interviews were used to explaining the results. The results of the study confirmed that both leadership practices associated with human capital, leadership practices associated with organizational culture, and leadership practices associated with balanced control were high, while leadership practices associated with future strategic intent were medium. Also There were statistically significant differences in strategic leadership practices due to gender and age. The explanations and recommendations were also proposed

THE BOUND STATES FOR THE NON POLYNOMIAL POTENTIAL VIA THE GENERALIZED DIFFERENTIAL QUADRATIC METHOD

In a previous work, we have introduced the generalized differential quadratic method (called GDQ) to handle the Schrödingerequation. This paper deals with a particular situation in which an application to the non polynomial potential is considered. Theresults are compared with some numerical examples for the same potential of interest. Dans un récent travail nous avons introduit la méthode quadratique différentielle généralisée pour manipuler l’équation deSchrödinger. Cet article traite une situation particulière dans laquelle une application à un potentiel non polynomial estconsidérée. Les résultats sont confrontés avec des exemples numériques pour le même potentiel d’intérêt

Prevalence of newly detected diabetes in pregnancy in Qatar, using universal screening.

Diabetes first detected during pregnancy is currently divided into gestational diabetes mellitus (GDM) and diabetes mellitus (DM)- most of which are type 2 DM (T2DM). This study aims to define the prevalence and outcomes of diabetes first detected in pregnancy based on 75-gram oral glucose tolerance test (OGTT)using the recent WHO/IADPSG guidelines in a high-risk population. This is a retrospective study that included all patients who underwent a 75 g (OGTT) between Jan 2016 and Apr 2016 and excluded patients with known pre-conception diabetes. The overall prevalence of newly detected diabetes in pregnancy among the 2000 patients who fulfilled the inclusion/exclusion criteria was 24.0% (95% CI 22.1-25.9) of which T2DM was 2.5% (95% CI 1.9-3.3), and GDM was 21.5% (95% CI 19.7-23.3). The prevalence of newly detected diabetes in pregnancy was similar among the different ethnic groups. The T2DM group was older (mean age in years was 34 ±5.7 vs 31.7±5.7 vs 29.7 ±5.7, p<0.001); and has a higher mean BMI (32.4±6.4 kg/m2 vs 31.7±6.2 kg/m2 vs 29.7± 6.2 kg/m2, p< 0.01) than the GDM and the non-DM groups, respectively. The frequency of pre-eclampsia, pre-term delivery, Caesarean-section, macrosomia, LGA and neonatal ICU admissions were significantly higher in the T2DM group compared to GDM and non-DM groups. Diabetes first detected in pregnancy is equally prevalent among the various ethnic groups residing in Qatar. Newly detected T2DM carries a higher risk of poor pregnancy outcomes; stressing the importance of proper classification of cases of newly detected diabetes in pregnancy.The authors received no specific funding for this wor

Study of some Macromycetes mushrooms; in the Atlas cedar forests of the Belezma massif (Batna, Algeria)

RESUME La richesse mycologique du massif de Belezma demeure très mal connue, car n’a jamais fait l’objet d’un inventaire. Ainsi ; cette étude porte sur l’étude du cortège fongique des cédraies dont l’objectif d’obtenir une liste la plus complète possible d’espèces de la zone considérée, dans le cadre d’un état des lieux initial de la fonge. La reconnaissance de la flore fongique a été faite sur une série de critères, à savoir les caractères morphologiques d’identification qui sont observés à l’œil nu et approfondies au laboratoire à l’aide d’une loupe binoculaire, des caractères organoleptiques tel que la couleur, saveur, odeur, toucher ; ont été ainsi déterminés et en fin des critères microscopiques à l’aide des coupes microscopiques au niveau des structures anatomiques. Notre étude, a permis d’inventorier 51 espèces dont 98.06 % de cette fonge appartient à la division de Basidiomycètes et 1.94 % aux Ascomycètes. Parmi ces dernières&nbsp;; 49 espèces ont été décrites pour la première fois dans la région du parc national de Belezma. La majorité des espèces rencontrées sont caractérisées des rôles importants et diversifiés. &nbsp; &nbsp; Mots clES: Fonge, morphologique, microscopiques, spore, Ascomycètes, Basidiomycètes, Belezma. &nbsp; ABSTRACT The phanerogamic flora of cedar forests that belonging to Belezma massif - Batna (Algeria) was partially studied; however its mycological richness remains largely unknown because it has never been inventoried. Thus; this&nbsp;study aimed to the investigate of the fungic procession&nbsp;of the cedar forests of which the objective to obtain the most complete possible list of species of the considered area&nbsp;; fully as possible within the framework of an initial inventory of fungi. The identification of fungal flora was based on a number of criteria, namely the macroscopic and microscopic morpphological characters, organoleptic characteristics such as the color, flavour, odor, touch; were thus determined and at the end of the microscopic criteria using the microscopic cuts on the level of the anatomical structures. Our study allowed us to inventory 51 species 98.06% of these fungi belong to the division Basidiomycetes and 1.94% to the Ascomycetes. Of these; 49 species have been met for the first time in the National Park area. The majority of the found species have important and diverse roles. &nbsp; Keywords: Fungi, morphologcal, microscopic, spore, Ascomycetes, Basidiomycetes, Belezma. &nbsp

ENANTIOSELECTIVE REDUCTION OF PROCHIRAL KETONES PROMOTED BY AMINO AMIDE RUTHENIUM COMPLEXES: A DFT STUDY

International audienceThe origin of enantioselectivity in the reaction of chiral Ru amino amide complexes in the asymmetric transfer hydrogenation of acetophenone was investigated using DFT calculations. For the most stable active catalysts, the full free energy profiles for the reaction were calculated according to the concerted hydrogen transfer mechanism. We succeeded in reproducing the experimentally observed enantioselectivity for the studied Ru amino amide complexes. Our results indicate that the high enantioselectivity can be explained by a stabilizing CH-π interaction existing between the phenyl group of acetophenone and the aromatic substituent of the catalyst, which plays a significant role in selectivity. Finally, our results show that important insights can be obtained with such a theoretical approach not simply to explain the origin of the reaction asymmetry but also to predict the enantiomeric excess. This can help experimentalists to design new enantioselective catalysts

Impact of the fear of Covid-19 infection on intent to breastfeed; a cross sectional survey of a perinatal population in Qatar

Objectives: Infection control measures during the Covid-19 pandemic have focused on limiting physical contact and decontamination by observing cleaning and hygiene rituals. Breastfeeding requires close physical contact and observance of hygienic measures like handwashing. Worries around contamination increase during the perinatal period and can be expressed as increase in obsessive compulsive symptoms. These symptoms have shown to impact breastfeeding rates. This study attempts to explore any relationship between the Covid-19 pandemic and perinatal obsessive-compulsive symptomatology and whether the Covid-19 pandemic has any impact on intent to breastfeed. Methods: A cross sectional survey of perinatal women attending largest maternity centre in Qatar was carried out during the months of October to December 2020. Socio-demographic information, intent to breastfeed and information around obsessive compulsive thoughts around Covid-19 pandemic were collected using validated tools. Results: 15.7% respondents report intent to not breastfeed. 21.4% respondents reported obsessive-compulsive symptoms. 77.3% respondents believed the biggest source of infection was from others while as only 12% of the respondents believed that the source of infection was through breastfeeding and 15.7% believed the vertical transmission as the main source of risk of transmission. Conclusions: The rates of Obsessive-compulsive symptoms were increased and the rates of intent to breastfeed were decreased when compared with pre pandemic rates. The obsessive-compulsive symptoms and the intent to not breastfeed were significantly associated with fear of infection to the new-born. Obsessive-compulsive symptoms were not significantly correlated with intent to breastfeed and can be seen as adaptive strategies utilized by women to continue breastfeeding in the context of fear of infection.The authors are grateful to the Qatar National Library for making this article available as open access.
