This paper follows the news routine of the daily evening news broadcasts of the two Israeli commercial TV channels. It is about a very particular and significant moment in national TV news—the making and gatekeeping process of the national TV news filler, also known by the Israeli news people as the shelf item. Based on a thematic analysis of in-depth interviews with several Israeli TV news professionals and a textual analysis of a particular TV news item and its shelf potential, findings provide a glimpse at how and for what reasons news stories are prioritized, how gatekeeping is performed in national TV news, and the ways in which the stories that are kept aside and left for later illustrate the overall production of newsworthiness. 相似文献

The thoughts of Mordecai Kaplan and Michael Rosenak present surprising commonalities as well as illuminating differences. Similarities include the perception that Judaism and Jewish education are in crisis, the belief that Jewish peoplehood must include commitment to meaningful content, the need for teachers to teach from a position of authenticity, and the importance of developing the inner life. The differences lie primarily in their divergent understandings of what in Judaism obligates, of the importance of reckoning with the Schwabian “milieu” when educating, of the acceptable boundaries of textual interpretation, and of the need to engage with families when educating children. 相似文献

Feelings of threat, challenge, motivation, self-efficacy, and transactional distance reflect students’ struggles with the learning process. This study examined the relationship between students’ subjective feelings about the learning process in virtual and blended courses (VC and BC). This is a mixed-method study. The sample included 484 students from two academic institutions in Israel. The study found a connection between students’ subjective feelings about the learning process in VC and BC and feelings of threat/challenge, motivation, and self-efficacy. We found differences between students in different years of study and between those studying in various fields of study. 相似文献

The aim of the present study was to find a more optimal blade design for rowing performance than the Big Blade, which has been shown to be less than optimal for propulsion. As well as the Big Blade, a flat Big Blade, a flat rectangular blade, and a rectangular blade with the same curvature and projected area as the Big Blade were tested in a water flume to determine their fluid dynamic characteristics at the full range of angles at which the oar blade might present itself to the water. Similarities were observed between the flat Big Blade and rectangular blades. However, the curved rectangular blade generated significantly more lift in the angle range 0-90 degrees than the curved Big Blade, although it was similar between 90 and 180 degrees. This difference was attributed to the shape of the upper and lower edges of the blade and their influence on the fluid flow around the blade. Although the influence of oar blade design on boat speed was not investigated here, the significant increases in fluid force coefficients for the curved rectangular blade suggest that this new oar blade design could elicit a practically significant improvement in rowing performance. 相似文献

Reuters established a picture service after its competitors. So why did it enter the picture market when it did? What advantage did late entry give it? How did this new technologically driven business model based on pictures offer the key bridge to the contemporary multimedia company Reuters is today? In this article, the story of the Reuters picture service is told for the first time since it was officially established in 1985. Using Reuters archive, it begins with the purchase of UPI's US pictures service and ends with the contemporary business. It explores the ways Reuters managed to finance the production of pictures; build a new network for the picture service; invest in (and develop) new technologies of distribution, consumption and operation while being constantly on guard through research; study its markets, its competitors and clients; make room for new product lines in the form of news pictures within an already fully operational organisation, and deal with difficulties that resulted from such structural changes. Establishing its picture service during the 1980s not only helped Reuters make a strong entry into the international image market at a time when international news had just entered a new digital era, it also helped Reuters build a strong business and technological model during a period of media industry upheaval. And it used its picture operations to establish an elaborative infrastructure, enabling this forward-looking multimedia business to become a powerful international news agency ready for the future. 相似文献

ABSTRACTMechanistic studies of the Functional Re-adaptive Exercise Device (FRED) have shown it automatically recruits Lumbar Multifidus (LM) and Transversus Abdominis (TrA) – two deep-spinal muscles that are atrophied and show altered motor control in low back pain (LBP). No studies have investigated the time required to familiarise to FRED exercise, which is required to inform future FRED based clinical trial protocols. This study therefore determined the effect of time, during FRED exercise, on biomechanical outcome measures, to establish the familiarisation period, and assess for loss of technique throughout a ten minute trial. A cohort comparison study of 148 participants, 70 experiencing low back pain, had lumbopelvic kinematics, exercise frequency and movement variability measured during a 10 minute trial. Magnitude-based inference was used to assess for familiarisation, using plots of variation over time with familiarised reference ranges. The no pain group took 170 seconds, and the back pain group took 150 seconds, to familiarise. A familiarisation period of at least 170 seconds (2.8 minutes) is recommended. This justifies, and provides a familiarisation time for use of the FRED as a motor control intervention. 相似文献
