解决分布式需求的内在冲突

2006年8月,GEN(I网络创新的全球化环境)项目组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。上期已经介绍第一部分——“分布式需求定义GENI的重心”,本期刊出第二部分——“解决分布式需求的内在冲突”。     

音乐改善鸡情绪

Clues to how some music can send chills down yourspine are being sought in the moods of chickens. Austrian and U.S.researchers have found that inyoung domestic chicks,the effects of music can be seenin behavioral changes.The experiment reveals:not so muchchicks’musical appreciadon,but hints(暗示,提示)at how the“language of emotions”might have evolved hand-in-handwith emotions.     

The ADHD spectrum and everyday life: experience sampling of adolescent moods, activities, smoking, and drinking

Using an experience sampling methodology, the everyday lives of 153 adolescents with low, middle, or high levels of attention-deficit/hyperactivity disorder (ADHD) characteristics as assessed by either parent or teen were examined. Twice each hour, across two 4-day recording intervals, participants in a longitudinal study of stress and health risks logged their behaviors, moods, and social contexts. Those with high, in contrast to low, ADHD symptom levels recorded more negative and fewer positive moods, lower alertness, more entertaining activities relative to achievement-oriented pursuits, more time with friends and less time with family, and more tobacco and alcohol use. Fewer associations emerged with parent-defined than with teen-defined subgroups, although the differences in alertness, peer and family contexts, entertainment versus achievement activities, and substance use were consistent across sources. Even at subclinical levels, ADHD characteristics were associated with behavioral patterns and contexts that may promote peer deviancy training, unhealthy lifestyle behaviors, and vulnerability to nicotine dependence.     

Multiple mentor model: A conceptual framework

Conclusion This article focused on developing a conceptual framework for the mentoring process. The model is based on the premise that mentoring is not a single event in the life of a worker but rather several events with different levels of mentoring. Each level of mentoring requires a different type of mentor with different types of skills and knowledge, similar to Len Nadler's HRD training model. Therefore, people may need special training to assume the different mentor levels (i.e., Training, Education, and Development Mentors), and workers may need to be trained to recognize that such experiences and people exist to help in their career progression. Counselors can be in the forefront as far as accepting and advocating the use of the Multiple Mentor Model for this training     

Research Agendas and Computer Technology Visions: The Need for Closely Watched Classrooms

There are numerous research methodologies that may be applied to the study of computer technology, and each has the potential to provide insights into its usefulness. The selection of research methodologies should be driven by the nature of the questions under investigation rather than a predetermined idea that some research methods are superior to others. This article focuses on a particular methodology, case studies, and it describes their potential for making a unique contribution to our understanding of computer technology. The special value of case studies lies in helping us understand the complexities found in classrooms, where the multiple variables that influence computer use interact in complex ways. © 1999 IFIP, published by Kluwer Academic Publishers     

Functional school refusal subtypes: Anxiety,avoidance, and malingering

Chronic school refusal has traditionally been classified under broad categories such as school phobia and truancy. However, the need for improved recognition and treatment of school refusal has heightened efforts to identify subtypes of school refusal behavior. Recent efforts have focused on functional subtypes of school refusal. This article purposes to extend recent efforts by showing that the three basic subtypes of anxiety, avoidance, and malingering are not only functional, but consistent with refusal characteristics, empirical evidence from factor analysis and clinical diagnosis over the past decade, and treatment approaches. Such extension is intended to aid practitioners in further understanding and using functional subtypes. © 2000 John Wiley & Sons, Inc.     

Index of science reading awareness: An interactive-constructive model,test verification,and grades 4–8 results

The purpose of this study was to develop and verify the Index of Science Reading Awareness (ISRA) based on a model of an efficient, successful interactive-constructive science reader and three independent metacognitive awareness domains. Several researchers have noted the need for efficient, reliable, and valid measures of metacognition. ISRA data collected on 532 students (Grades 4–8) were analyzed using factor analyses, linear structural modeling, and analyses of variance (ANOVAs) to help verify the model and the test. The factor analyses and linear structural modeling indicated that these data did not support the assumption about the three independent metacognitive awareness domains, but suggested that the model and the test were structured around the design features of science reading, science text, and science reading strategies. One-way ANOVAs indicated significant, predicted reading ability and gender differences but unexpected grade-level differences. The composite metacognitive awareness data indicated that most Grade 4–8 students have surface knowledge about science reading, science text, and science reading strategies, and indicated specific targets for explicit science reading instruction. © 1998 John Wiley & Sons, Inc.

Assessment Focus in Studio: What is Most Prominent in Architecture,Art and Design?

What can be learned about assessment from what educators in the creative practices focus their studio publications on? What should form the focus of assessment in architecture, art and design studios? In this article we draw on 118 journal articles on studio published over the last decade in three disciplines; architecture, art and design to inform the focus of studio assessment. We believe that what is published by educators themselves in these disciplines reveals what matters most to them. In addition, we argue that regardless of the primary emphasis placed in each discipline, assessment in studio should encompass a broad set of indicators. Within the wider literature including in architecture, art and design, a view of assessment is emerging that recognises the process and the person, beyond a view that positions the product or art/design arte‐fact above all else. Therefore, drawing on what educators in architecture, art and design mentioned most in the journal publications analysed, as well as the literature on good assessment, we offer a holistic model to guide and take studio assessment in the creative disciplines further.     

Gender and Management in HEIs: Changing organisational and management structures

This paper reports on the second phase of a multi-country study examining cross cultural perspectives of gender and management in Higher Education Institutions (HEIs). It examines the broader labour market context and legislative frameworks for higher education in each country and then analyses the literature on women in university management. The paper presents the findings of research with male and female senior managers about their perceptions of women as HEI managers within changing organisational and management structures. It concludes that although HEI’s are now largely aware of barriers to women getting into and on in senior management, they have not addressed the organisational structures and cultures that perpetuate this inequity.
