The effect of ball carrying method on sprint speed in rugby union football players

Different methods of ball carrying can be used when a player runs with the ball in rugby union. We examined how three methods of ball carrying influenced sprinting speed: using both hands, under the left arm and under the right arm. These methods were compared with running without the ball. Our aim was to determine which method of ball carrying optimizes sprinting speed. Altogether, 48 rugby union players (age 21 +/- 2 years, height 1.83 +/- 0.1 m, body mass 85.3 +/- 12 kg, body fat 14 +/- 5%; mean +/- s) were recruited. The players performed twelve 30-m sprints in total (each player performed three trials under each of three methods of carrying the ball and sprinting without the ball). The design of the study was a form of Latin rectangle, balanced across the trial order for each of the methods and for pairwise combinations of the methods in blocks of four per trial. Each sprint consisted of a 10-m rolling start, followed by a 20-m timed section using electronic timing gates. Compared with sprinting 20 m without the ball (2.58 +/- 0.16 s), using both hands (2.62 +/- 0.16 s) led to a significantly slower time (P < 0.05). Sprinting 20 m with the ball under the left arm (2.61 +/- 0.15 s) or under the right arm (2.60 +/- 0.17 s) was significantly quicker than when using 'both hands' (P < 0.05), and both these methods were significantly slower than when running without the ball (P < 0.05). Accordingly, running with the ball in both hands led to the greatest decrement in sprinting performance, although carrying the ball under one arm also reduced the players' sprinting ability. Our results indicate that to gain a speed advantage players should carry the ball under one arm.     

The context dependence of physics identity: Examining the role of performance/competence,recognition, interest,and sense of belonging for lower and upper female physics undergraduates

While there is a growing body of work that examines disciplinary identity development, unlike qualitative work in this area, quantitative research has not fully incorporated the importance of different contexts, nor has it uniquely focused on underrepresented groups (in this case, women in physics). This study examines how the constructs posited by prior work as important for physics identity, as well as an additional theorized construct, may interrelate and affect female students' physics identity differently depending on the context. Context in this study refers to two different experiential levels in college. The constructs examined include performance/competence, recognition, and interest, as well as sense of belonging. In particular, we used structural equation modeling to examine the effect that these constructs have on the physics identity of two groups of female physics undergraduates: first year students and senior year students. The results reveal that the relationship of the theorized constructs with physics identity vary between the two groups as well as compared to prior research with broad college student populations (not just physics majors). Unlike broad college student populations, for our sample of female physics undergraduates, interest did not have a direct effect on physics identity while sense of belonging was significant only for senior year students. These results exemplify the importance of examining context or different types of student experiences when studying disciplinary identity development rather than generalizing previous frameworks to all contexts.     

Unmasking text plagiarism using syntactic-semantic based natural language processing techniques: Comparisons,analysis and challenges

The proposed work aims to explore and compare the potency of syntactic-semantic based linguistic structures in plagiarism detection using natural language processing techniques. The current work explores linguistic features, viz., part of speech tags, chunks and semantic roles in detecting plagiarized fragments and utilizes a combined syntactic-semantic similarity metric, which extracts the semantic concepts from WordNet lexical database. The linguistic information is utilized for effective pre-processing and for availing semantically relevant comparisons. Another major contribution is the analysis of the proposed approach on plagiarism cases of various complexity levels. The impact of plagiarism types and complexity levels, upon the features extracted is analyzed and discussed. Further, unlike the existing systems, which were evaluated on some limited data sets, the proposed approach is evaluated on a larger scale using the plagiarism corpus provided by PAN¹ competition from 2009 to 2014. The approach presented considerable improvement in comparison with the top-ranked systems of the respective years. The evaluation and analysis with various cases of plagiarism also reflected the supremacy of deeper linguistic features for identifying manually plagiarized data.     

The Influence of Religiosity and Ethnic Identification on Media Use Among Muslims and Non-Muslims in France and Britain

This is an examination of the ethnic media use of French and British Muslims. A total of 677 Muslims participated in the study. Analysis reveals being an immigrant or a native of a nation does not significantly influence ethnic media use in France but does in Britain. Ethnic identification was also revealed as an influential predictor of ethnic media use among Muslims in France but not in Britain. Religiosity significantly predicted ethnic media use among British Muslims. The article argues religiosity and ethnic identification should be included in studies examining media use among ethnic groups.     

A Test of the Relationships between Host and Home National Involvements and the Preferences for Intercultural Conflict Management Styles

This study focused on the relationships between host national (host interpersonal communication) and home national (ethnic interpersonal communication) involvements and preferences for conflict management styles in the context of a conflict with a member of the host culture. Two hypotheses that examined the relationships between these variables and the preferences for the integrating, the compromising, the avoiding, the obliging and the dominating styles were proposed. Survey data from two hundred and sixty-nine, international and exchange, students were analyzed. The results revealed that the level of host national involvement positively predicted the preferences for the integrating and the obliging styles, and the level of home national involvement positively predicted the preference for the avoiding style. These findings suggest the need to consider contextual influences in understanding the complexities that underlie intercultural communication and adaptation.     

“Air Anatomy” – Teaching Complex Spatial Anatomy Using Simple Hand Gestures

Spatial understanding of complex anatomical concepts is often a challenge for learners, as well as for educators. It is even more challenging for students with low mental spatial abilities. There are many options to teach spatial relationships, ranging from simple models to high-end three-dimensional (3D) virtual reality tools. Using a randomized controlled trial design, this study explored the use of a unique combination of deictic and iconic hand gestures to enhance spatial anatomical understanding, coining the term “Air Anatomy”. The control group (n = 45) was given a lecture on the anatomy of extraocular muscles, while the intervention group (n = 49) received the same lecture including “Air Anatomy” hand gestures. When compared to the control group, the post-test scores for the intervention group were significantly higher for basic recall (P < 0.001; Mann–Whitney U test) and for the application of knowledge (P = 0.015; Mann–Whitney U test). Students with low to moderate spatial ability (as assessed by a mental rotation test) were found to benefit most by this technique. Students in the intervention group also reported a lower extrinsic cognitive load and higher germane load, when compared to the control group. An instructional skills questionnaire survey indicated the effectiveness of this technique in improving overall classroom experience. Feedback of the students in the intervention group was also favorable for instruction using “Air Anatomy”. The study suggests that “Air Anatomy” is a useful, “no-cost”, accessible method that aids spatial understanding of anatomical concepts.     

Mass media,class, and democracy: the struggle over newspaper representation of the UPS strike

–This paper investigates whether organized labor can challenge the news media's pro-corporate representations of strikes and labor struggles. I studied the coverage of the 1997 UPS strike in three newspapers: USA Today, The Washington Post, and The New York Times. I found that their strike coverage, spanning about 191 articles, went through three distinct phases over the 15-day period. By studying these phases I agree that, for a brief period, public opinion and class solidarity, mobilized on the basis of a strike against corporate mistreatment of workers, played a key role in changing the tone of reporting, particularly in the Post and the Times. During this phase, the contradictions of the 1990s economic recovery and the problems of the working class became an issue of sustained interest in the public sphere. By showing how labor was able briefly to create an “open marketplace of ideas,” the paper concludes with an assessment of the democratizing potential of a politicized labor movement.     

Media,War, and Propaganda: Strategies of Information Management During the 2003 Iraq War

It is now widely acknowledged that the Bush administration used faulty and false information to justify the 2003 war on Iraq, and that the mainstream media, by not adequately investigating the case for war, assisted with the project. In this paper, I outline the particular strategies employed by the media–military industrial complex to ensure a dominance of pro-war arguments in the public sphere. I conclude by arguing that the failure of the media in the US to meet the democratic needs of this society places enormous responsibility on intellectuals to produce scholarship critical of the new imperialism.     

PCT as a Prognostic Marker in Cardiac Patients with Neutropenic Sepsis: Two Case Reports

Procalcitonin (PCT) is an innovative and highly specific marker for diagnosis of clinically relevant bacterial infection and sepsis. PCT supports early diagnosis and Clinical decision making. A retrospective study of two classical cases of neutropenic sepsis with elevated PCT levels in cardiac ICU was done. PCT was analyzed using Elecsys Brahms PCT kit. Serum PCT levels <0.5 ng/ml and ANC <1,000/mm³ was taken as cutoff. The first patient had initial high levels of PCT 100 ng/ml, TLC 13,600/mm³ and ANC 12,250/mm³. It was followed by drop with subsequent rise in PCT levels and drop in TLC 1,000/mm³ and ANC 70/mm³. The second patient had normal PCT 0.116 ng/ml, TLC 5,600/mm³ and ANC 4,420/mm³ levels followed with sharp increase in all the values with subsequent drop in TLC 2,000/mm³ and ANC 880 cells/mm³. Both the patients died of neutropenic sepsis with multiorgan failure. The case reports showed the correlation of PCT with TLC and ANC levels in predicting the mortality of patients with neutropenic sepsis in cardiac ICU.     

Customers or Academic Trainees? An Experimental Investigation to Reduce Academic Entitlement in the College Classroom

Academic entitlement (AE) in students has been found to be associated with maladaptive practices in the classroom. By experimentally manipulating the content of instructor teaching philosophies, this study attempted to encourage students to view themselves as academic trainees with the intention to decrease AE. Undergraduate students (N = 351) were randomly assigned to read one of two versions of a teaching philosophy that framed education either as a transactional or intellectual experience. Results showed that students in the transactional condition were more likely to enact a customer role, whereas participants in the intellectual condition were more likely to play an academic trainee role. Furthermore, the customer role was associated with heightened AE in participants and an increased intention to negotiate grades with instructors.
