Chinese EFL students' response to an assessment policy change

In light of its documented potential for enhancing learning, formative assessment has been adopted across a range of educational contexts to improve the quality of education. The assessment innovation that the Chinese Ministry of Education (CMoE) proposed to College English in 2007 via the College English Curriculum Requirements (CECR) (CMoE, 2007), is an initiative of this kind. Considering the acknowledged influence of assessment on students’ learning, it is instructive to explore the ways in which Chinese university students respond to an assessment policy change of this magnitude, particularly as it positions them as more active learners, having the potential for increased agency and engagement in their English language learning and assessment practices. In order to explore the response of students to this assessment initiative, a case study was conducted in the context of a College English classroom. Data included an interview with a College English teacher and four students from her classes, and classroom observations and a survey of her two classes of 100 students. Analysis of the data reveals that Chinese students’ responses to the assessment policy change are influenced by a variety of sociocultural factors, including their previous English language learning and assessment experience and the extent to which they are willing to play the ‘assessment game’. These findings have implications for policy and practice.

Setting the agenda, influencing public opinion, and advocating for social change

This study seeks to contribute to the systematic explanation of journalists’ professional role orientations. Focusing on three aspects of journalistic interventionism – the importance of setting the political agenda, influencing public opinion and advocating for social change – multilevel analyses found substantive variation in interventionism at the individual level of the journalist, the level of the media organizations, and the societal level. Based on interviews with 2100 journalists from 21 countries, findings affirm theories regarding a hierarchy of influences in news work. We found journalists to be more willing to intervene in society when they work in public media organizations and in countries with restricted political freedom. An important conclusion of our analysis is that journalists’ professional role orientations are also rooted within perceptions of cultural and social values. Journalists were more likely to embrace an interventionist role when they were more strongly motivated by the value types of power, achievement and tradition.

Very high resolution optical satellites for DEM generation : a review

The advent of very high resolution (VHR) optical satellites capable of producing stereo images led to a new era in extracting digital elevation model which commenced with the launch of IKONOS. The special specifications of VHR optical satellites besides, the significant economic profit stimulated other countries and companies to have their constellations such as EROS-A1 and EROS-B1 as the cooperation between Israel and ImageSat. QuickBird, WorldView-1 and WorldVew-2 were launched by DigitalGlobe. ALOS and GeoEye-1 were offered by Japan and GeoEye Respectively. In addition to aforementioned satellites, Indian and South Korea initiated their own constellation by launching CartoSat-1 and KOPOSAT-2 respectively.The availability of all so-called satellites make a huge market of stereo images for extracting of digital elevation model and other correspondent applications such as, producing orthorectifcatin images and updating maps. Therefore, there is a need for a comprehensive comparison for scientific and commercial clients to choose appropriate satellite images and methods of generating digital elevation model to obtain optimum results. This paper will thus give a review about the specifications of VHR optical satellites. Then it will discuss the automatic elaborating of digital elevation model. Finally an overview of studies and corresponding results is reported.

Supine to standing Cobb angle change in idiopathic scoliosis : the effect of endplate pre-selection

Background Supine imaging modalities provide valuable 3D information on scoliotic anatomy, but the altered spine geometry between the supine and standing positions affects the Cobb angle measurement. Previous studies report a mean 7°-10° Cobb angle increase from supine to standing, but none have reported the effect of endplate pre-selection or whether other parameters affect this Cobb angle difference. Methods Cobb angles from existing coronal radiographs were compared to those on existing low-dose CT scans taken within three months of the reference radiograph for a group of females with adolescent idiopathic scoliosis. Reformatted coronal CT images were used to measure supine Cobb angles with and without endplate pre-selection (end-plates selected from the radiographs) by two observers on three separate occasions. Inter and intra-observer measurement variability were assessed. Multi-linear regression was used to investigate whether there was a relationship between supine to standing Cobb angle change and eight variables: patient age, mass, standing Cobb angle, Risser sign, ligament laxity, Lenke type, fulcrum flexibility and time delay between radiograph and CT scan. Results Fifty-two patients with right thoracic Lenke Type 1 curves and mean age 14.6 years (SD 1.8) were included. The mean Cobb angle on standing radiographs was 51.9° (SD 6.7). The mean Cobb angle on supine CT images without pre-selection of endplates was 41.1° (SD 6.4). The mean Cobb angle on supine CT images with endplate pre-selection was 40.5° (SD 6.6). Pre-selecting vertebral endplates increased the mean Cobb change by 0.6° (SD 2.3, range −9° to 6°). When free to do so, observers chose different levels for the end vertebrae in 39% of cases. Multi-linear regression revealed a statistically significant relationship between supine to standing Cobb change and fulcrum flexibility (p = 0.001), age (p = 0.027) and standing Cobb angle (p < 0.001). The 95% confidence intervals for intra-observer and inter-observer measurement variability were 3.1° and 3.6°, respectively. Conclusions Pre-selecting vertebral endplates causes minor changes to the mean supine to standing Cobb change. There is a statistically significant relationship between supine to standing Cobb change and fulcrum flexibility such that this difference can be considered a potential alternative measure of spinal flexibility.

The effect of endplate preselection when measuring supine versus standing cobb angle change in idiopathic scoliosis

The primary aim of this study was to determine whether endplate pre-selection makes a difference to the Cobb Angle change between supine and standing which is known to occur in idiopathic scoliosis. A secondary aim of this study was to identify which (if any) patient characteristics were correlated with supine versus standing Cobb change. The study found that pre-selecting vertebral endplates causes only has a minor effect on supine to standing Cobb change in scoliosis. There is a statistically significant relationship between supine to standing Cobb Angle change and fulcrum flexibility. Therefore, supine to standing Cobb Angle change can be considered as a measure of spinal flexibility when both standing and supine images are clinically available.

Regulating Workplace Risks: A Comparative Study of Inspection Regimes in Times of Change

Regulating Workplace Risks is a study of regulatory inspection of occupational health and safety (OHS) and its management in five countries – Australia, Canada (Québec), France, Sweden and the UK – during a time of major change. It examines the implications of the shift from specification to process based regulation, in which attention has been increasingly directed to the means of managing OHS more systematically at a time in which a major restructuring of work has occurred in response to the globalised economy. These changes provide both the context and material for a wider discussion of the nature of regulation and regulatory inspection and their role in protecting the health, safety and well-being of workers in advanced market economies.

Leadership Enabling Effective Pedagogic Change in Higher Education

This chapter will consider pedagogic change in Higher Education from the perspective of an Assistant Dean (Teaching and Learning) and one member of their leadership team with particular focus on reflective writing in their courses. The discussion will focus on leadership for the development of teaching capability for reflective writing development and implications for quality assurance of teaching and learning across faculties of a leading comprehensive University. The authors will present and contrast the experiences and challenges of developing teaching approaches for reflective writing across the discipline of teacher education. The chapter will argue a position for the establishment of a framework of distributed leadership that supports effective pedagogical change management generally and with specific reference to reflective writing.
