GENI的设计原则(一)分布式需求定义GENI的重心

2006年8月,GEN(I网络创新的全球化环境)公布其项目的设计原则。来自普林斯顿大学、麻省理工大学、华盛顿大学等学校的十二位专家编写了这份报告。该报告阐述了GENI的研究范围、用户的需求、需求的内在压力以及工程设计的原则。报告指出了GENI的价值主张,广泛的部署、多样化可扩展的网络技术集合、对真实用户流量的支持仍是GENI关注的原则和方向。本刊将分两期连载这一报告,从“分布式需求定义GENI的重心”、“解决分布式需求的内在冲突”等两部分,将这一报告与大家共享。     

加拿大移民法变化趋势

最近几年我多次访问中国的经历使我深深感受到中国人对加拿大移民法规与移民政策的浓厚兴趣,而中国经常流传着许多有关加拿大移民法将改动的内容的流言,这些流言通常是不正确的。如寻找与加拿大移民政策有关的信息或指南,便一定要查询适当的资料来源。加拿大公民及移民部当然是最可靠的信息来源地,因为它是主管加拿大移民法规的加拿大政府机构。     

Public sea turtle watches serve as effective environmental education

To understand both immediate and longer-term effects of a short duration, interpretive wildlife tourism program, we studied responses from participants in a sea turtle watch program. This program comprised an interpretive presentation followed by an opportunity to view a nesting loggerhead sea turtle (Caretta caretta). We conducted 37 programs in 2013 and 2014, for 843 participants, of whom 70.5% were able to see a nesting turtle. We measured participant attitudes, knowledge, intention to act, and long-term behavior change. Initial participant responses indicated prior interest in nature and environmental topics, and a knowledge base focused on biological sea turtle information. After the interpretive presentation, participants chose to provide conservation-related information as opposed to natural history-related information. Intention to engage in conservation behaviors was high following the turtle watch experience, regardless of whether a turtle was seen. The conservation value of our turtle watch program is expressed through conservation-focused knowledge acquisition by participants and their high post-program intention to engage in behaviors benefiting sea turtles, both of which precede long-term behavior change in an interdisciplinary model of behavior change.     

Validating written feedback in clinical formative assessment

Abstract

Formative assessment is widely accepted as being crucial to promoting student learning and, since 2010, the UK General Medical Council has mandated its use in workplace-based clinical training for all new doctors. As a result, the Royal College of Radiologists (RCR) instituted a range of formative workplace-based assessments including the Radiology Direct Observation of Procedural Skills (Rad-DOPS), in which supervisors appraise trainees’ performance in carrying out clinical procedures. This paper reports on the quality of the written feedback in 2,500?Rad-DOPS online feedback forms in addressing the aims of the new assessment approach. Random samples of 500 were selected from the first three years of the new assessment implementation, 2010–13, and from 2016 to 17. Using an appropriate coding frame, the feedback was analysed across the samples against key trainee attributes including stage of training and level of adjudged competence. Criteria for identifying high quality feedback were derived from the literature and a simplified form of qualitative comparative analysis was used to identify the conditions associated with high quality feedback. An average of 97% of the assessments contained written feedback but the number of instances of high quality feedback was found to be exceedingly small at around 5%. The paper offers suggestions for making the feedback process more purposeful in achieving the aims of formative assessment.     

The junior secondary history curricula in Hong Kong and Shanghai: a comparative study

Since 1997, Hong Kong's reintegration with China has been founded on the principle of ‘One Country, Two Systems’, which serves to guarantee the sustainability of the capitalist system in Hong Kong under the rule of the socialist motherland. This paper is an intra‐cultural and inter‐regional comparative study of the curricula of two systems (socialist and capitalist) under one country, using the junior secondary History curricula in Shanghai and Hong Kong as a case study. In addition to tracing the differences and similarities, divergences and convergences in the junior secondary History curricula of the two systems, the paper also generates proposals for the future improvement of History education in both cities.     

“It’s about respect!” college-athlete activism and left neoliberalism

This essay offers a critique of left neoliberalism with reference to certain tendencies in cultural studies, antiracist politics, disparity discourse, and college sports. Where the dominant tendency in cultural studies has been to produce complex analyses of identity-based oppression, this article insists on a conception of class politics that, on the one hand, calls for more attention to exploitation and, on the other, de-emphasizes the “working-class identity” model. By examining two recent episodes of athlete activism in college sports—namely, the much-admired “strike against racism” at the University of Missouri in 2015 and the widely condemned (and ultimately unsuccessful) effort by Northwestern University football players to form a union in 2014—the article contends that the commitment to eliminating racism and indifference to ending exploitation in these contexts reflects the broader commitments of a “left-wing” neoliberalism that devotes itself to ending inequality without redistributing wealth.
