This paper focuses on the war correspondents traveling in the Balkans during the period of the Balkan Wars (1912–1913) to cover military campaigns. It tries to explore the paths of information, the mechanisms of propaganda and the restrictions used by the Balkan states to control the content of the news transmitted. The Balkan Wars were among the first military events covered so extensively by newspapers all around the world. In the battle-fields the principles of the new field of journalism were highly tested. The lessons learnt in the Balkans during the Balkan Wars proved to be productive and useful for the improvement of the relationship between war correspondents and military authorities.  相似文献

This article sheds light on an understudied aspect of the transition from school to work: the choice of a training company. It presents findings from qualitative interviews with 69 secondary school students and apprentices from the German states of Berlin and Brandenburg, focusing on their reasons to choose a training company in the dual system. What reasons lead students and apprentices to choose a training company? The most common reason is personal impressions, which future apprentices obtain in their initial, personal encounters with a company and its staff. Students and apprentices often consider location, working atmosphere and soundness. Due to this study’s regional scope, its findings may not be fully generalisable on a national or international level. However, its findings may instigate further research in countries where people pursuing certain types of apprenticeship training have to apply to companies (e.g. Great Britain, Switzerland and Australia).  相似文献

Teacher–student discourse continues to be teacher-centred even though researchers and reform documents have recommended changes toward increased levels of student-centred discourse. In science education this situation is paralleled by effort to make scientific inquiry more student-centred. The purpose of this study was to investigate how discourse forms changed over time in a classroom where the regular teacher and his students were scaffolded in the transitioning to student-centred scientific inquiry. Video-recordings were collected at intervals over one academic year. Three prominent forms of discourse were identified: two teacher-authoritative forms and one more interactive, dialogic form. As the lessons increasingly turned into student-centred scientific inquiry, a shift to the dialogic discourse form was found. Co-teaching provided for (a) guidance towards an organisation of events in the classroom that included regular teacher–student dialogue (b) modelling of the more dialogic form of discourse.  相似文献

For this critical intercultural inquiry, I as an Asian/Japanese transnational cisgendered gay man write my autoethnography of queer (or non-heteronormative) Asian–Black (dis)connections. Specifically, I challenge, interrogate, and problematize my queer intercultural production of desire and attraction as I engage in my critical autoethnographic interrogation of dialogues with five Asian/Japanese transnational gay men who have previously engaged in queer Asian–Black relationality. In so doing, I intend to create a potential point of departure to decenter the discursive and material effects of White gay normativity in the knowledge production of Asian queer male desire and attraction.  相似文献

Body position is known to alter power production and affect cycling performance. The aim of this study was to compare mechanical power output in two riding positions, and to calculate the effects on critical power (CP) and W′ estimates. Seven trained cyclists completed three peak power output efforts and three fixed-duration trial (3-, 5- and 12-min) riding with their hands on the brake lever hoods (BLH), or in a time trial position (TTP). A repeated-measures analysis of variance showed that mean power output during the 5-min trial was significantly different between BLH and TTP positions, resulting in a significantly lower estimate of CP, but not W′, for the TTP trial. In addition, TTP decreased the performance during each trial and increased the percentage difference between BLH and TTP with greater trial duration. There were no differences in pedal cadence or heart rate during the 3-min trial; however, TTP results for the 12-min trial showed a significant fall in pedal cadence and a significant rise in heart rate. The findings suggest that cycling position affects power output and influences consequent CP values. Therefore, cyclists and coaches should consider the cycling position used when calculating CP.  相似文献

In longitudinal design, investigating interindividual differences of intraindividual changes enables researchers to better understand the potential variety of development and growth. Although latent growth curve mixture models have been widely used, unstructured finite mixture models (uFMMs) are also useful as a preliminary tool and are expected to be more robust in identifying classes under the influence of possible model misspecifications, which are very common in actual practice. In this study, large-scale simulations were performed in which various normal uFMMs and nonnormal uFMMs were fit to evaluate their utility and the performance of each model selection procedure for estimating the number of classes in longitudinal designs. Results show that normal uFMMs assuming invariance of variance–covariance structures among classes perform better on average. Among model selection procedures, the Calinski–Harabasz statistic, which has a nonparametric nature, performed better on average than information criteria, including the Bayesian information criterion.  相似文献

The English writer Thomas Tryon (1634–1703) believed that sheep were survivors from the original earthly paradise, and that as morally perfect beings they could serve as role models for humans. Tryon advocated vegetarianism, pacifism and an end to slavery as it was practiced in the Caribbean. He was an ambitious and influential reformer on several fronts, but the restoration of Eden was his ultimate goal. Tryon celebrated sheep-like meekness, a stance that complicated his reform efforts. His agenda and sheep-inspired persuasive strategy reflect the momentous intellectual and moral ferment surrounding human relations with animals in the seventeenth century.  相似文献

ABSTRACT

Although sports heritage is increasingly recognized as a potential catalyst of tourism, heritage sporting events (HSEs) are still an emerging concept in the academic literature. Notions that associate sports events and heritage remain rare, and are usually analysed through the scope of nostalgia sport tourism. This can be partly explained by an inclination to associate the notion of heritage with conventional ideas about folklore and traditional culture. Through a constructivist approach of heritage, this contribution argues that contemporary sports events, which would generally have competition as their primary focus, might also be perceived as HSEs. A comprehensive framework, built on a multi-disciplinary literature review, is presented to show the process that transforms an initial resource (a sports event) into an accomplished resource (a HSE), which might represent a competitive advantage for the territory. A qualitative–comparative analysis is conducted among 24 sports events in the French-speaking part of Switzerland, to observe the configurations of HSEs and understand which characteristics are necessary for the perceptions of a sports event as a heritage good. Interestingly, this contribution shows that if the event needs to be sustainable in the territory to be perceived as a HSE, it is not sufficient. Indeed, a differentiation strategy should be set up to distinguish the event from other more or less similar events, to be perceived as an authentic feature of the territory by the local population.  相似文献

This study aimed to explore the strength of the force–velocity (FV) relationship of lower limb muscles and the reliability of its parameters (maximum force [F0], slope [a], maximum velocity [V0], and maximum power [P0]). Twenty-three men were tested in two different jump types (squat and countermovement jump: SJ and CMJ), performed under two different loading conditions (free weight and Smith machine: Free and Smith) with 0, 17, 30, 45, 60, and 75?kg loads. The maximum and averaged values of F and V were obtained for the FV relationship modelling. All FV relationships were strong and linear independently whether observed from the averaged across the participants (r?≥?0.98) or individual data (r?=?0.94–0.98), while their parameters were generally highly reliable (F0 [CV: 4.85%, ICC: 0.87], V0 [CV: 6.10%, ICC: 0.82], a [CV: 10.5%, ICC: 0.81], and P0 [CV: 3.5%, ICC: 0.93]). Both the strength of the FV relationships and the reliability of their parameters were significantly higher for (1) the CMJ over the SJ, (2) the Free over the Smith loading type, and (3) the maximum over the averaged F and V variables. In conclusion, although the FV relationships obtained from all the jumps tested were linear and generally highly reliable, the less appropriate choice for testing the FV relationship could be through the averaged F and V data obtained from the SJ performed either in a Free weight or in a Smith machine. Insubstantial differences exist among the other combinations tested.  相似文献

This article contributes to the important debate over the conversion of the Turks to Islam. Previously, it was thought that the Turks abandoned their former steppe faith and customs very swiftly to become staunch Sunni Muslims, but this view has recently been challenged by a number of studies. The current consensus seems to be that the Turks’ adoption of Islam was a process of far longer duration, spanning many decades. This article broadens this discussion by demonstrating that the chronicles written by the First Crusaders contain much useful information that is pertinent to this question. It works through these texts, showing that they can shed new light on this point.  相似文献
