Jingoism,Public Opinion,And The New Imperialism     

Simon J. Potter 《Media History》2014,20(1):34-50

This essay analyses late-Victorian understandings of the relationship between the press, imperial diplomacy, and popular enthusiasm for empire, and examines how newspapers explained their own role in the imperial rivalries of the 1890s. During imperial disputes between Britain and France (particularly the Fashoda crisis) and between Britain and the USA (the Venezuela boundary dispute) contemporaries claimed that self-interested ‘jingo’ elements of the political elite had sought to foment conflict by manipulating ‘public opinion’, but had been defeated by statesmen (who had used the press for legitimate diplomatic purposes) and by ‘the people’ (who were averse to war). This contrasted with contemporary comments about the role played by the press in provoking wars between the USA and Spain and between Britain and the Transvaal: both the press and the people seemed to succumb to an irrational popular ‘jingoism’, and to sweep statesmen along in their wake. However, this essay argues that these contemporary verdicts about the role of newspapers in focusing popular imperialism have been too easily accepted by historians. During the imperial rivalries of the 1890s the press played an important role as a medium of transnational communication, but did not push statesmen into expansionism.  相似文献   

More than basketball: Determining the sport components that lead to long-term benefits for African-American girls     

Joyce O. Olushola  D. Floyd Jones  Marlene A. Dixon  B. Christine Green 《Sport Management Review》2013,16(2):211-225

Sport participation has the capacity to enhance the athletic and academic performance of adolescents. However, African-American participants have not enjoyed the positive academic benefits that are common among other populations. Sport is a popular developmental intervention for African-American youth, yet sport programs do not always render the intended benefits (Coalter, 2007). The purpose of this study was to determine the components of school-based sport programs that create long-term benefits for African-American girls. A high school basketball program based on positive youth development served as the program site. Data were collected through semi-structured interviews with current and former players and program stakeholders. Four key values underpin the success of the program: family, education, discipline, and civic engagement. The results indicate that successful programs need flexible—not standard—design commitment to program values, and consistency in mission and implementation. Implications for the design and implementation of sport programs to improve the athletic and academic performance of African-American girls are discussed.  相似文献   

Touching practice and physical education: deconstruction of a contemporary moral panic     

Simon Fletcher 《Sport, Education and Society》2013,18(5):694-709

This paper explores the insecurities and discursive moral panics elicited by the discussion of intergenerational touch in education, and their subsequent manifestation in ‘classroom panopticism’. In a number of contexts, public hysteria has grown around the interaction between adult and child, and whether this interaction stays within the narrow parameters of a generally consensual ‘acceptability’. Crossing these boundaries carries grave consequences for those deemed to be exploiting their position and this has had significant implications for the self-identity of practitioners. This climate of preventative fear has also served to manipulate regulatory method, realigning conceptions of practitioner independence. Drawing on interviews with Physical Education teachers in English secondary schools, and applying a Foucauldian theoretical framework, with particular reference to his interpretation of panopticism, this paper investigates the conceptual transformation of contemporary education. Whilst school spaces were once representative of stability, in which roles were clearly defined, the hierarchical dynamic has changed. The teacher, who previously presided with relative professional freedom and autonomy, is now subject to myriad pressures associated with ‘appropriate’ behaviour and the avoidance of any ‘problematic’ interactional incident. Foucault's treatment of panopticism is apt here, as teachers must conduct themselves with an acceptance that they are now governed by an unpredictable yet persistent practical scrutiny.  相似文献   

Hydrodynamics of undulatory underwater swimming: A review     

Chris Connaboy  Simon Coleman  Ross H. Sanders 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(4):360-380

Undulatory underwater swimming (UUS) occurs in the starts and turns of three of the four competitive swimming strokes and plays a significant role in overall swimming performance. The majority of research examining UUS is comparative in nature, dominated by studies comparing aquatic animals' undulatory locomotion with the UUS performance of humans. More recently, research directly examining human forms of UUS have been undertaken, providing further insight into the factors which influence swimming velocity and efficiency. This paper reviews studies which have examined the hydromechanical, biomechanical, and coordination aspects of UUS performance in both animals and humans. The present work provides a comprehensive evaluation of the key factors which combine to influence UUS performance examining (1) the role of end-effector frequency and body amplitudes in the production of a propulsive waveform, (2) the effects of morphology on the wavelength of the propulsive waveform and its subsequent impact on the mode of UUS adopted, and (3) the interactions of the undulatory movements to simultaneously optimise propulsive impulse whilst minimising the active drag experienced. In conclusion, the review recommends that further research is required to fully appreciate the complexity of UUS and examine how humans can further optimise performance.  相似文献   

Kinematics and kinetics of the bench-press and bench-pull exercises in a strength-trained sporting population     

Simon N. Pearson  John B. Cronin  Patria A. Hume  David Slyfield 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(3):245-254

Understanding how loading affects power production in resistance training is a key step in identifying the most optimal way of training muscular power – an essential trait in most sporting movements. Twelve elite male sailors with extensive strength-training experience participated in a comparison of kinematics and kinetics from the upper body musculature, with upper body push (bench press) and pull (bench pull) movements performed across loads of 10–100% of one repetition maximum (1RM). 1RM strength and force were shown to be greater in the bench press, while velocity and power outputs were greater for the bench pull across the range of loads. While power output was at a similar level for the two movements at a low load (10% 1RM), significantly greater power outputs were observed for the bench pull in comparison to the bench press with increased load. Power output (P _max) was maximized at higher relative loads for both mean and peak power in the bench pull (78.6 ± 5.7% and 70.4 ± 5.4% of 1RM) compared to the bench press (53.3 ± 1.7% and 49.7 ± 4.4% of 1RM). Findings can most likely be attributed to differences in muscle architecture, which may have training implications for these muscles.  相似文献   

Effect of combined carbohydrate-protein ingestion on markers of recovery after simulated rugby union match-play

Abstract

In this study, we investigated the effect of ingesting carbohydrate alone or carbohydrate with protein on functional and metabolic markers of recovery from a rugby union-specific shuttle running protocol. On three occasions, at least one week apart in a counterbalanced order, nine experienced male rugby union forwards ingested placebo, carbohydrate (1.2 g · kg body mass^?1 · h^?1) or carbohydrate with protein (0.4 g · kg body mass^?1 · h^?1) before, during, and after a rugby union-specific protocol. Markers of muscle damage (creatine kinase: before, 258 ± 171 U · L^?1 vs. 24 h after, 574 ± 285 U · L^?1; myoglobin: pre, 50 ± 18 vs. immediately after, 210 ± 84 nmol · L^?1; P < 0.05) and muscle soreness (1, 2, and 3 [maximum soreness = 8] for before, immediately after, and 24 h after exercise, respectively) increased. Leg strength and repeated 6-s cycle sprint mean power were slightly reduced after exercise (93% and 95% of pre-exercise values, respectively; P < 0.05), but were almost fully recovered after 24 h (97% and 99% of pre-exercise values, respectively). There were no differences between trials for any measure. These results indicate that in experienced rugby players, the small degree of muscle damage and reduction in function induced by the exercise protocol were not attenuated by the ingestion of carbohydrate and protein.  相似文献   

Crossing the Line: Sport and the Limits of Civil Rights Protest     

Simon Henderson 《国际体育史杂志》2013,30(1):101-121

Scholars have ably considered the extent to which sport has been, and continues to be, a force for racial progress. What has been less comprehensively explored, however, are the unique difficulties encountered by athletes who have attempted to use sport to promote civil rights activism. Black athletes, and sympathetic white teammates, have faced considerable obstacles as sportsmen who supported the civil rights struggle. Sport has restricted the ability of sportsmen to successfully engage in civil rights activism. In the belief that it has provided an example of racial progress for the rest of society, in fact, sport has resisted the civil rights movement. This article explores the difficulties faced by athletes who attempted to be part of that movement.  相似文献   

Observed characteristics and teacher quality: Impacts of sample selection on a value added model     

Marcus A. Winters  Bruce L. Dixon  Jay P. Greene 《Economics of Education Review》2012

We measure the impact of observed teacher characteristics on student math and reading proficiency using a rich dataset from Florida. We expand upon prior work by accounting directly for nonrandom attrition of teachers from the classroom in a sample selection framework. We find evidence that sample selection is present in the estimation of the influence of teacher characteristics, but that failure to account for it does not appear to substantially bias estimation. Further, our procedure produces some evidence that more effective teachers are more likely to exit the classroom.  相似文献   

Purpose and preference in educational podcasting     

Rob Van Zanten  Simon Somogyi  Gina Curro 《British journal of educational technology : journal of the Council for Educational Technology》2012,43(1):130-138

The application of podcasting for educational purposes is growing fast in universities. There are several benefits of this asynchronous, direct communication and interaction between teacher and student. Nonetheless, the benefits, the pedagogical value of podcasting the traditional lecture format, have come into question. Furthermore, issues have been raised regarding lengthy and costly download times, and the fact that students need to make time to listen to them. For these reasons, using short 3–5‐minute podcasts that summarise the lecture have been suggested. This paper explores how students interact with different types of podcasts. The study compares download and course evaluation data of a series of short‐summary podcasts with full‐lecture podcasts produced for the same university course. The findings show that students value full‐lecture podcasts as highly as the short‐summary podcasts, despite the fact that full‐lecture podcasts are downloaded to a markedly lesser degree. The cause of this anomaly appears to lie in the different purposes that dictate podcast use. The paper concludes by noting that both full‐lecture and short‐summary podcasts serve as useful tools for student learning in university contexts.  相似文献
