An appraisal of techniques and equipment for cutting force measurement

INTRODUCTION Metal machining processes are characterised mainly by quick changes in quantified elements. In- dividual changes do not occur in isolation and they influence each other. The analysis of these changes require study of the complicated complete systems in their real situations. The study of cutting processes such as turning and facing, from dynamic aspects, is very important. The trend towards the measurement of cutting forces in machining leads to many theo- retical and practic…     

Informational sources,self-efficacy and achievement: a temporally displaced approach

Personal self-efficacy is an important theoretical orientation that helps to explain students’ learning and academic achievements. One area of research inquiry has involved the four major sources of information and their predictive effects on self-efficacy. As an extension for examination, the purpose of our investigation was to explore the interrelations between antecedents (e.g. enactive performance accomplishment), self-efficacy beliefs and academic achievement of elementary school students. Our research conceptualisation, unlike previous cross-sectional studies, entails a time displacement between sources of information (Time 1) and self-efficacy (Time 2 and Time 3) and between self-efficacy and academic achievement in science learning (Time 4). Three hundred and thirty-two (152 girls and 180 boys) third and fourth grade students from three government schools participated in this study. Likert-scale inventories were used to measure informational sources and self-efficacy beliefs. Structural equation modelling yielded evidence that supports, in part, our conceptual model. Only enactive performance accomplishment and vicarious experience exerted positive temporally displaced effects on self-efficacy. Self-efficacy at both Time 2 and Time 3 also contributed to the prediction of academic achievement.     

客家童谣的特点及其教育价值

作为一种极具童趣和乡土气息的语言形式,客家童谣是非常具有地域文化特色的综合教育素材,对儿童语言、艺术、社会性、科学认识等方面的健康发展有着激发和促进的重要价值.幼儿园一方面应有针对性地对客家童谣进行全面整合,在其中融入时代的因素,拓展客家童谣的文化内涵,另一方面应借鉴客家童谣的形式,编写信息量大、图文并茂、地方特色浓厚的正规启蒙教材,从而既保存童谣这一客家口头文化的珍品,又充分发挥其对现代幼儿教育的重要补充作用.     

The Effect of Personal and Academic Variables on Student Adoption of Twitter as an Information Source

ABSTRACT

This study investigated the use of Twitter in terms of personal and academic variables of students. These included gender, grade point average (GPA), and year level. Data were collected from undergraduate students at the College of Social Sciences at Kuwait University. A structured questionnaire was used as the data collection instrument. The findings show that the majority of respondents use social media, 42.8% use Twitter “sometimes,” and 44.4% use it “always.” There is no significant difference between males and females, except for social influence (SI). There is a statistically significant difference in the use of Twitter as an information source among students for different academic year levels, with the highest mean for senior students. However, no significant differences were found by students' GPA scores. Further investigation focusing on variables such as students' level of confidence and skills of using Twitter, such as the effect of course content, etc., would provide more insight into the use of social media platforms in higher education.     

Bridging Generations

Abstract

Since 1994, undergraduate students at Rutgers University have had the opportunity to explore broad issues in the history of women's higher education by examining issues surrounding single-sex and coeducation at their own institution, with specific concentration on social issues and student culture. Four distinct seminars and projects, two of which incorporate oral history, and all four involving historical research in archival sources, have contributed to the historical literature and have added valuable documentation on the history of women at Rutgers University. This article presents an overview of these specific courses. It further provides an assessment from the particular perspective of a university archivist who attempts to document the history of the institution, promote the use of that documentary record by a diverse audience of users, including undergraduate students, and who has had the opportunity to teach two seminars on the history of women's higher education, using Rutgers as a case study. The courses to be discussed are: “Rutgers Women: A Living History” (1993-1995), a research seminar incorporating oral history of the first women students to enter the previously all-male Rutgers College in 1972; the Rutgers Oral History Archives of World War II (1994 to present), an ongoing project recording the memories of Rutgers men and women and their wartime experiences; the Douglass College Scholar's Program seminar on psychobiography (1998), a seminar which explored the life of Mary Clara Kangler, a 1938 graduate of the New Jersey College for Women whose tragic life ended in suicide; and the Douglass College Scholar's Program seminar on the history of the Douglass College and its role in the history of women's higher education in the United States (1999-2002), a research seminar based on archival research which explored the experiences of women and the controversial issues surrounding women's education at Rutgers.
