Our argument in this paper is that the model of literary progression which Bakhtin (1981, 1986) expounds in his writing on the chronotope can generate insight into the processes through which pupils improve their writing. We suggest more generally that there are concepts and clues in Bakhtin's historical model of the development of the European novel and in his theory of dialogue which can be helpful in both the evaluation and teaching of classroom writing. 相似文献

The lack of widely available, affordable broadband Internet access has spurred a movement in which municipalities are rolling out wireless broadband networks. This movement has raised a number of questions including: Why are municipalities acting as the early adopters of wireless broadband technology? How does increased state regulation of municipal broadband networks affect this trend and how can cities respond? As cities use wireless broadband technology to enhance services to citizens, the growth of municipal wireless deployments has transitioned from linear to exponential. In response, many states have passed laws to regulate and restrict cities' ability to own, operate, deploy, or profit from either telecommunications or information services. Current and pending laws will be examined to understand how cities can deploy a wireless broadband network under these regulations. An analysis of municipal facilities and technology expertise illustrates the opportunity for public–private cooperation in wireless deployments. This paper will show that cooperation is beneficial in many cases. Finally, current business models will be examined for their ability to foster cooperation between the public and private sectors, bridge the digital divide, and create competition among private sector providers. 相似文献

As academic library collections are moved off site to make room for learning commons-type collaboration spaces, exploratory research processes (e.g. stacks browsing activities) are threatened. Given the range of benefits associated with chance information encounters in the physical book stacks, the disappearance of accessible collections is problematic. Fortunately, by focusing on embodied aspects of the physical browsing experience we can leverage emerging technologies to preserve instances of serendipitous information retrieval. Virtual reality, in this case, provides a browsing platform that allows for the type of search activity typically associated with research in the physical books stacks and preserves the benefits thereof. 相似文献

The release of the Old World Drought Atlas (OWDA) in November 2015 provides historians with an unprecedented glimpse into the climate of the medieval world. Through the careful examination of tree-ring data provided by the OWDA, historians can better gauge how the environment affected the course of medieval Mediterranean history, particularly in times and places where textual data is sparse, such as North Africa. The case studies of the Norman conquest of the coast of Ifrīqiyya in the 1140s and the invasion by the Banū Hilāl in the mid-eleventh century show the utility of the OWDA for gaining a better understanding the medieval Mediterranean. In particular, OWDA data shows that the arrival of the Banū Hilāl into Ifrīqiyya coincided with a period of extended drought that is not documented in the written sources and suggests that increased competition for scarce resources was instrumental to their entrance into the region. 相似文献

ABSTRACTThis study aimed to assess the effect of playing surface (Natural [NT] and Artificial [AT] Turf) on the fatigue response to a soccer-specific exercise protocol (SSEP). Eighteen male soccer players completed the SSEP on NT and AT with pre-, post-, and 48 h post-assessments of eccentric knee flexor (eccKF) and concentric knee extensor peak torque (PT), peak countermovement (CMJ) and squat jump (SJ) height, and Nordic hamstring break angle. No significant main effects for surface or any surface and time interactions were observed for any of the outcome measures, except for eccKF PT recorded at 3.14 rad·s-1, which was significantly lower 48 h post-trial in the AT condition (AT = 146.3 ± 20.4 Nm; NT = 158.8 ± 24.7 Nm). Main effects for time were observed between pre- and post-trial measures for eccKF PT at all angular velocities, Nordic break angle, CMJ and SJ height. Nordic break angle, and both CMJ and SJ height were significantly impaired 48 h post-trial when compared to pre-trial. The findings of the current study suggest surface dependent changes in eccKF PT which may have implications for recovery and subsequent performance after competition on AT. 相似文献

Counselors (N = 911) reported the research skills needed for practice and subsequent research training needs. Findings indicate that counselors have a high need for research skills at work, but training needs differ significantly by counselor type. Recommendations include increasing emphasis on single‐case design, survey design, and widely available data analysis tools. 相似文献
