The relationship between student’s MBTI, preferences and academic performance at a Syrian university
Get PDFPurpose: The main purpose of this paper is to find whether a correlation exists between students’ natural preferences or what is known as psychological type as determined by the Myers-Briggs Type Indicator (MBTI); the extent of their enthusiasm measured by their level of “like” to the subject, and students’ grade point average (GPA). Design/methodology/approach: Data were collected from 89 students who took the MBTI inventory in five selected faculties at Damascus University in Syria. In order to rate the subjects’ like or dislike level, the students were asked to complete a form prepared for this purpose. The students’ GPAs were also included in the analysis. Findings: Using paired sample t-test, the results indicate a statistically significant correlation between type of student and his/her faculty of study, type of student and overall study subject like, and type of student and his/her GPA. There was, however, a statistically significant correlation between various personality dichotomies of the type (Extraversion-Introversion, Sensing-Intuition, Thinking-Feeling, Judging-Perceiving) and faculty, individual subjects like, and GPA. The study also indicates a statistically significant correlation between study like and GPA, and faculty and GPA. The most critical conclusion from the study is that Sensing-Intuition dichotomy of the MBTI inventory has the strongest correlation to distribution of students among faculties, the subject's like or dislike, and the GPA. In addition, the higher the level of like for a subject, the higher the GPA is. Research limitations/implications: The study results were based on a sample of students from a specific subject area of study. To validate the results of the study, future research is highly needed on a larger sample of students from different subject disciplines. Practical implications: Empirically, this study provides decision makers of the higher education sector with relevant information regarding the intended future attempts to reform the university admission policy with regards to the career path. Originality/value: The usefulness of MBTI inventory has not been assessed in the Arab countries before. This study is therefore considered as one of the initial studies in this field
Biomechanical evolution of the Tkachev on uneven bars in female gymnastics
Get PDFThe development of joint kinematics and kinetics is fundamental to the successful performance of complex flight skills
in gymnastics bar routines. Biomechanical understanding of these skills can provide coaches and scientists with key
information to make training safe and effective. The Tkachev is a complex and popular gymnastics skill with many different variations. Recently, a new version has been performed, which has become popular with elite female performers.
This study examined the key biomechanical characteristics of this skill and contrasted these to the earlier versions
reported. Elite female gymnasts (n = 5) were recorded and manually digitised using twin video cameras (50 Hz) at the
2007 World Gymnastics Championships. Three-dimensional (3D) DLT was used to reconstruct the real world coordinates. Individualised inertia characteristics were calculated and used to determine mass centre kinematics. Inverse
dynamics analysis was used to calculate joint kinetics at the hips and shoulders from the known values at the toes. The
results of this study showed an increased flight time and rotational capacity during the aerial phase for the toe-on Tkachev, as well as a more simple movement pattern and joint kinetic demand with single power impulses at the hips and
shoulders compared with previous versions. The key finding of this study was that the toe-on version appeared to be less
physically demanding than that the inward and outward techniques, and provide the opportunity to perform more complex aerial phase body positions. These results can help coaches to physically prepare their gymnasts and biomechanists
in terms of understanding the demands of these skills
Experiences of physical activity: A phenomenological study of individuals with cystic fibrosis
Get PDFAlthough extensive research has investigated the benefits of physical activity in cystic fibrosis, minimal exploration of the experiences for individuals from a qualitative, phenomenological perspective has been carried out. The aim of this study was to explore the subjective experiences of physical activity for individuals with cystic fibrosis. The health-care team, at an Adult Cystic Fibrosis Unit in the United Kingdom, recruited 12 participants to take part. Interview data were analysed using interpretative phenomenological analysis. A central theme of ‘self-monitoring’ emerged from the accounts and was embedded in the three super-ordinate themes
The new IOC and IAAF policies on female eligibility: old Emperor, new clothes?
Get PDFThe Caster Semenya debacle touched off by the 2009 Berlin World Athletics Championships resulted finally in IOC and IAAF abandonment of sex testing, which gave way to procedures that make female competition eligibility dependent upon the level of serum testosterone, which must be below the male range or instrumentally countered by androgen resistance. We argue that the new policy is unsustainable because (i) the testosterone-performance connection it posits is uncompelling; (ii) testosterone-induced female advantage is not ipso facto unfair advantage; (iii) the new policy reflects the gender policing impulses endemic to sport as well as the broader cultural impulses to monstrify women and to doctor women who have nothing wrong with them; (iv) female–male performance disparities are not the only reason for sex-segregated sport, but co-exist with respectable cultural and practical reasons, which (v) provide a powerful case for allowing athletes to compete in the sex category congruent with their gender identity
Activity theory, complexity and sports coaching: An epistemology for a discipline
Get PDFThe aim of this article is two-fold. Firstly, it is to advance the case for Activity Theory (AT) as a credible and alternative lens to view and research sports coaching. Secondly, it is to position this assertion within the wider debate about the epistemology of coaching. Following a framing introduction, a more comprehensive review of the development and current conceptualisation of AT is given. Here, AT’s evolution through three distinct phases and related theorists, namely Vygotsky, Leont’ev and Engeström, is initially traced. This gives way to a more detailed explanation of AT’s principal conceptual components, including ‘object’, ‘subject’, ‘tools’ (mediating artefacts), ‘rules’, a ‘community’ and a ‘division of labour’. An example is then presented from empirical work illustrating how AT can be used as a means to research sports coaching. The penultimate section locates such thinking within coaching’s current ‘epistemological debate; arguing that the coaching ‘self’ is not an autonomous individual, but a relative part of social and cultural arrangements. Finally, a conclusion summarises the main points made, particularly in terms in presenting the grounding constructivist epistemology of AT as a potential way forward for sports coaching
Honey as an effective antimicrobial treatment for chronic wounds: is there a place for it in modern medicine?
Get PDFHoney has a long history in the treatment of wounds, where claims of its therapeutic properties include the inhibition of a wide range of infectious agents as well as an ability to promote rapid wound healing. However, honey is not a uniform product, and its chemical composition can be influenced by multiple factors. The availability of modern, licensed dressings containing medical grade honey has garnered renewed interest in its clinical potential for conventional wound care. Laboratory investigations are beginning to explain at a cellular and molecular level the effects of specific honeys on certain microorganisms, but the clinical evidence of its antimicrobial effects is limited at present. The aim of this review is to demonstrate the chemical complexity of honey, to describe the mechanisms of antibacterial action reported to date, and to collate the evidence that provides insight into antimicrobial claims for honey
Nation, state and identity in international sport
Get PDFThe question of eligibility for international sporting representation (ISR) has become increasingly contentious. In this paper we argue that the current ISR regulations are outdated and problematic. Sporting governing bodies ought to ignore citizenship as a criterion for ISR, and instead ISR should be based on a normative account of national belonging which would operate primarily on grounds of early socialisation and longterm residency. This approach would avoid many of the pragmatic and moral pathologies of ISR, and would utilise sports potential in promoting a liberal and progressive understanding of national ties
Restart: The Resurgence of Computer Science in UK Schools
Get PDFComputer science in UK schools is undergoing a remarkable transformation. While the changes are not consistent across each of the four devolved nations of the UK (England, Scotland, Wales and Northern Ireland), there are developments in each that are moving the subject to become mandatory for all pupils from age 5 onwards. In this article, we detail how computer science declined in the UK, and the developments that led to its revitalisation: a mixture of industry and interest group lobbying, with a particular focus on the value of the subject to all school pupils, not just those who would study it at degree level. This rapid growth in the subject is not without issues, however: there remain significant forthcoming challenges with its delivery, especially surrounding the issue of training sufficient numbers of teachers. We describe a national network of teaching excellence which is being set up to combat this problem, and look at the other challenges that lie ahead
Factors associated with low fitness in adolescents – A mixed methods study
Get PDFBackground:
Fitness and physical activity are important for cardiovascular and mental health but activity and fitness levels are declining especially in adolescents and among girls. This study examines clustering of factors associated with low fitness in adolescents in order to best target public health interventions for young people.
Methods:
1147 children were assessed for fitness, had blood samples, anthropometric measures and all data were linked with routine electronic data to examine educational achievement, deprivation and health service usage. Factors associated with fitness were examined using logistic regression, conditional trees and data mining cluster analysis. Focus groups were conducted with children in a deprived school to examine barriers and facilitators to activity for children in a deprived community.
Results:
Unfit adolescents are more likely to be deprived, female, have obesity in the family and not achieve in education. There were 3 main clusters for risk of future heart disease/diabetes (high cholesterol/insulin); children at low risk (not obese, fit, achieving in education), children ‘visibly at risk’ (overweight, unfit, many hospital/GP visits) and ‘invisibly at risk’ (unfit but not overweight, failing in academic achievement). Qualitative findings show barriers to physical activity include cost, poor access to activity, lack of core physical literacy skills and limited family support.
Conclusions:
Low fitness in the non-obese child can reveal a hidden group who have high risk factors for heart disease and diabetes but may not be identified as they are normal weight. In deprived communities low fitness is associated with non-achievement in education but in non-deprived communities low fitness is associated with female gender. Interventions need to target deprived families and schools in deprived areas with community wide campaigns
A comparative analysis of the corrosive effect of artificial saliva of variable pH on DMLS and cast Co-Cr-Mo dental alloy
Get PDFAbstract: Dental alloys for direct metal laser sintering (DMLS) are available on the market today, but there is little scientific evidence reported on their characteristics. One of them is the release of ions, as an indicator of the corrosion characteristics of a dental alloy. Within this research, the difference in the elution of metals from DMLS and cast (CM) samples of Co-Cr-Mo dental alloy in saliva-like medium of three different pH was examined by inductively-coupled plasma mass spectrometry (ICP-MS). The obtained results show that the metal elution in artificial saliva from the DMLS alloy was lower than the elution from the CM alloy. The release of all investigated metal ions was influenced by the acidity, both from the DMLS and CM alloy, throughout the investigated period of 30 days. The change in acidity from a pH of 6.8 to a pH of 2.3 for the cast alloy led to a higher increase of the elution of Co, Cr and Mo from CM than from the DMLS alloy. The greatest release out of Co, Cr and Mo was for Co for both tested alloys. Further, the greatest release of all ions was measured at pH 2.3. In saliva of pH 2.3 and pH 4.5, the longer the investigated period, the higher the difference between the total metal ion release from the CM and DMLS alloys. Both alloys showed a safe level of elution according to the ISO definition in all investigated acidic environments
