ABSTRACT

As the world is witnessing the epidemic of coronavirus disease 2019, emerging genetics and clinical pieces of evidence suggest a similar immunopathology to those of severe acute respiratory syndrome and Middle East respiratory syndrome. Staying at home to prevent the spread of the virus and consequently being largely inactive is associated with unintended consequences. These can actually enhance the infection risk and exacerbate poor health conditions including impaired immune function. Physical activity is a feasible way of improving health, particularly physical and mental health in a time of social isolation. However, people with certain health conditions in these circumstances may need a special physical activity programme in addition to any exercise they may already be performing via online programmes. This review aims to provide practical guidelines during the COVID-19 quarantine period. We suggest performing aerobic, resistance training, respiratory muscle training and yoga in the healthy, and in those with upper respiratory tract illness, patients with lower respiratory tract illness should be restricted to respiratory muscle training and yoga. In addition, vitamins D and C, omega-3 fatty acids, and regular consumption of fruit and vegetables might be considered as nutritional aids to support the immune system in those affected by COVID-19.  相似文献   

Writer identification approach based on bag of words with OBI features     

Amal Durou  Ibrahim Aref  Somaya Al-Maadeed  Ahmed Bouridane  Elhadj Benkhelifa 《Information processing & management》2019,56(2):354-366

Handwriter identification aims to simplify the task of forensic experts by providing them with semi-automated tools in order to enable them to narrow down the search to determine the final identification of an unknown handwritten sample. An identification algorithm aims to produce a list of predicted writers of the unknown handwritten sample ranked in terms of confidence measure metrics for use by the forensic expert will make the final decision.Most existing handwriter identification systems use either statistical or model-based approaches. To further improve the performances this paper proposes to deploy a combination of both approaches using Oriented Basic Image features and the concept of graphemes codebook. To reduce the resulting high dimensionality of the feature vector a Kernel Principal Component Analysis has been used. To gauge the effectiveness of the proposed method a performance analysis, using IAM dataset for English handwriting and ICFHR 2012 dataset for Arabic handwriting, has been carried out. The results obtained achieved an accuracy of 96% thus demonstrating its superiority when compared against similar techniques.  相似文献   

Kinematic analysis of the drag flick in field hockey     

Rony Ibrahim  Gert S. Faber  Jaap H. van Dieën 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(1):45-57

Attaining high speed of the stick head and consequently of the ball is essential for successful performance of the drag flick in field hockey, but the coordination pattern used to maximise stick head speed is unknown. The kinematics of the drag flick was studied in ten elite hockey players who performed twenty shots each towards a target located 1.5 m high. A 150 Hz active marker motion analysis system was used, alongside two force plates to detect foot touchdown. Angular velocity and contribution to stick endpoint speed of upper body joints were analysed. Repeated measures ANOVA was used to compare timing of onset and peak angular velocities between joints. Participants used a kinematic pattern that was close to a proximal-to-distal sequence. Trunk axial rotation and lateral rotation towards the target, right wrist flexion and left wrist extension were the main contributors to stick endpoint speed. Coaches should emphasise trunk rotations and wrist flexion and extension movements for maximising stick head speed. Given the high level of the participants in this study, the coordination of joints motions, as reported here, can serve as a guideline for drag flick training.  相似文献   

A corpus-based discourse analysis of the vision and mission statements of universities in Turkey     

Ibrahim Efe 《高等教育研究与发展》2015,34(6):1110-1122

This article presents findings from a corpus-assisted discourse analysis of mission and vision statements of 105 state and 66 private/foundation universities in Turkey. The paper combines a corpus-based approach with critical discourse analysis to interpret the data in relation to its institutional as well as socio-political context. It argues that the mission and vision statements are marked by a need for reassuring their legitimacy and the demands of a growing tertiary market. The historical and cultural backgrounds of the development of universities in Turkey, as well as political and economic conditions, are also decisive in the shaping of mission and vision statement of universities.  相似文献   

Modelling parenting styles,moral intelligence,academic self-efficacy and learning motivation among adolescents in grades 7–11     

Amal Alhadabi  Said Aldhafri  Hussain Alkharusi  Ibrahim Al-Harthy  Marwa Alrajhi  Hafidha AlBarashdi 《Asia Pacific Journal of Education》2019,39(1):133-153

The current study investigated the associations between three maternal and paternal parenting styles, moral intelligence, academic self-efficacy and learning motivation in three serial mediation models. Omani adolescents enrolled in 7th to 11th grades (N = 296) responded to an online survey containing demographic items and scales measuring the variables noted above. Results of Path Analysis indicated that the three models had a good overall fit. In detail, the three paternal styles (authoritative, authoritarian and permissive) had direct associations with moral intelligence and indirect associations with learning motivation. However, only two maternal parenting styles (i.e., authoritative and authoritarian) correlated directly with learning motivation and these two styles did not associate with moral intelligence. All effects were in the hypothesized direction except the effect of authoritative maternal and paternal styles. Moral intelligence had a positive direct correlation with students’ academic self-efficacy and learning motivation. Moral intelligence also mediated the negative associations between three types of fathers’ parenting styles and students’ motivation. Academic self-efficacy had a positive association with students’ motivation. These findings provided useful insights about the various association between external factors (e.g., parenting styles), internal factors (i.e., moral intelligence and self-efficacy) and students’ motivation among adolescents in middle and high schools.  相似文献   

Towards a traditional model for school counselling and care in Nigeria     

Ibrahim Bulus 《International journal for the advancement of counseling》1989,12(2):105-112

This paper attempts to present a traditional model that can be used for school counselling in the Nigerian school system.To do this, it discusses beliefs and values in a traditional setting, healing and characteristics of traditional counselling environment and the traditional healing processes. Finally, it gives a discourse on a model for therapy in Nigerian schools.The emphasis of the paper is that it is necessary for school counselling to be marshed with the traditional model as the students schools seek to nurture, ultimately, still go back to tradition for self-realization and self-actualization.  相似文献   

Morpho-Phonemic Similarity within and between Languages: A Factor to be Considered in Processing Arabic and Hebrew     

Raphiq Ibrahim 《Reading and writing》2006,19(6):563-586

The goal of the present study was to explore the pattern of lexical connections between translation equivalents represented in the cognitive system of an Arabic-Hebrew bilingual. To achieve this goal, repetition priming effects (reaction times (RTs) and accuracy measures) were compared between translation equivalents in the two forms of Arabic, Spoken Arabic (SA) and Literary Arabic (LA), with those between translation equivalents in Hebrew and LA, in native Arabic students living in Israel. While these students master Hebrew as well as they master LA, they consider it as a second language. LA targets were preceded by cognate and non-cognate translation equivalents in SA or Hebrew either immediately (Lag 0) or separated by four unrelated words (Lag 4), in a lexical decision task. The participants were requested to make a word/non-word decision regardless of language. Across languages, morpho-phonemic similarities augmented the repetition priming effects. At Lag 0 this effect was larger when the primes were in Hebrew than when they were in SA. At Lag 4, however, the priming effect between Hebrew and LA was significantly reduced (and even absent for non-cognates). In contrast, the priming effect between Spoken and Literary Arabic was only slightly attenuated. The conclusion was that, despite the intensive daily use and psychological proximity, Spoken and Literary Arabic are represented as first and second languages in the cognitive system of the native Arabic reader, entertaining distinct lexica. However, the strength of the lexical associations between translation equivalents is influenced by the frequency of concomitant use.  相似文献

Palestinian media landscape: Experiences,narratives, and agendas of journalists under restrictions     

Ibrahim Hazboun  Ifat Maoz  Menahem Blondheim 《The Communication Review》2019,22(1):1-25

This study aims to increase our understanding of the dynamics of the Palestinian media and the conditions and circumstances in which they work, including both the conflict with Israel and the internal political strife within Palestinian society. It is based on the use of qualitative research methods and was conducted in two stages. First, we performed a mapping of Palestinian media outlets. Data on these Palestinian media outlets were collected online from the West Bank-based Palestinian Authority’s Ministry of Information website, the Gaza-based Hamas government’s Ministry of Information website, and statements published by Palestinian media outlets on their websites describing their affiliation and ownership. Second, to gain a more in-depth understanding of the dynamics and experience of practicing journalism in a situation of asymmetrical conflict, semistructured in-depth interviews were conducted with 25 professional local Palestinian journalists working for local media outlets in the Gaza Strip, the West Bank, and East Jerusalem. Through this study we aim to learn more about how groups shape and express their narratives and agendas through the media when restricted by the conditions, pressures, and limitations of asymmetrical conflict.  相似文献   

Effect of perceived ease of use on librarians' e-skills: Basis for library technology acceptance intention     

Roland Izuagbe  Nurudeen Ademola Ibrahim  Lilofa Osamienfa Ogiamien  Olajumoke Rebecca Olawoyin  Nwanne Mary Nwokeoma  Promise Ifeoma Ilo  Odaro Osayande 《Library & information science research》2019,41(3):100969

Despite the widespread application of technology in the 21st century, making informed decisions regarding its acceptance in organisations is a function of several factors, particularly in developing countries, due to factors such as rising cost of the information technology infrastructure and low technological exposure. A model that incorporated perceived ease of use (PEOU) and e-Skills to examine librarians' intention for actual library technology acceptance was tested. The correlational research design, along with a multistage sampling procedure, was applied to select samples to reduce the sample to a manageable proportion. Professional librarians and library officers in four university libraries provided the data for the study. Results showed that e-Skill is the model's strongest determinant of technology acceptance intention among librarians. Also, PEOU will significantly moderate librarians' intention towards library technology acceptance when e-Skills are insufficient. From these outcomes, the understanding of the determinants of behavioural intention captured in the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAT) is extended and refined.  相似文献
