Undergraduate engineering students’ attitudes and perceptions towards ‘professional ethics’ course: a case study of India

‘Professional Ethics’ has been offered as a compulsory course to undergraduate engineering students in a premier engineering institution of India. It was noticed that students’ perceptions and attitudes were frivolous and ornamental towards this course. Course instructors and institution authorities were motivated to find out the factors contributing to this awkwardness. For this purpose, a questionnaire was prepared and administrated to 336 students registered for the July–November 2014 semester. The study found two factors contributing to students’ indifference towards the Professional Ethics course. First, most of the students did not have self-interest to join the engineering programme, and while pursuing their study, they decided to switch to a different field upon completion of their engineering study. Second, students who desired to be engineers in their future believed that engineering code of ethics is not really referred to in most of the engineering jobs, and therefore Professional Ethics course is only meant for classroom discussions.     

BCH—LT级联码的分析与设计

通过把无码率LT码和BCH码进行级联,构造了一类性能优异的级联码,并且提出了软判决迭代译码算法,应用在内外码的译码过程中,解决了错误平层问题。通过仿真可知,在加性高斯白噪声二进制对称信道中,该级联码在很宽的信噪比下具有较好的性能,可以进行可靠的传输。     

基于迹准则的超正交空时格码的设计

为了改进超正交空时格码的设计,提出了基于迹准则的设计方法.分析了传统基于秩行列式准则设计方法的缺点,以及基于迹准则设计的优点.研究了基于迹准则的设计方法中STBC方案、集分割、网格结构、信号子集与STBC方案在网格中的分配这四大要素的优化原则,并依据这一原则给出了码的系统化手工设计的具体步骤.再通过星座扩展的方法,可以使设计出的码性能进一步提高.文中给出了码的设计结果,仿真表明得到的新码具有更好的性能.     

Honor Codes and Other Contextual Influences on Academic Integrity: A Replication and Extension to Modified Honor Code Settings

Research has shown that traditional academic honor codes are generally associated with lower levels of student academic dishonesty. Utilizing data obtained from students at 21 colleges and universities, this study investigated the influence of modified honor codes, an alternative to traditional honor codes, that is gaining popularity on larger campuses. It also tested the model of student academic dishonesty previously suggested by McCabe and Treviño in a more diverse sample of campuses. Results suggest that modified honor codes are associated with lower levels of student dishonesty and that the McCabe and Treviño model appears to be reasonably robust.     

Rethinking Our Mobility: Supporting Our Patrons Where They Live

This article describes initiatives undertaken by one academic medical library to support patrons using handheld mobile devices. These initiatives included efforts to assist patrons with installation and use of mobile information resources, educate librarians regarding content and navigation of mobile apps and websites, and leverage tools to promote the library in a mobile environment.     

A code-based approach for labeling in complex irregular regions

Labeling information in a complex irregular region is a useful procedure occurring frequently in sheet metal and the furniture industry which will be beneficial in parts management. A fast code-based labeler （FCBL） is proposed to accomplish this objective in this paper. The region is first discretized, and then encoded by the Freeman encoding technique for providing the 2D regional information by 1D codes with redundancies omitted. We enhance the encoding scheme to make it more suitable for our complex problem. Based on the codes, searching algorithms are designed and can be extended with customized constraints. In addition, by introducing a smart optimal direction estimation, the labeling speed and accuracy of FCBL are significantly improved. Experiments with a large range of real data gained from industrial factories demonstrate the stability and millisecond-level speed of FCBL. The proposed method has been integrated into a shipbuilding CAD system, and plays a very important role in ship parts labeling process.     

团体操表演功能：仪式、文化与艺术

摘要：团体操表演功能的研究,对明确团体操艺术发展的方向具有基石性的作用,亦是为体育院校原创新学科提供理论依据的一项基础性研究。研究采用文献资料以及44部国家级团体操视频资料统计法,运用文化人类学、象征学、语言学等工具,以团体操起源、表演形式与各种仪式的交汇、手段要素为线索探讨团体操表演功能。得出：团体操起源于斯拉夫民族国家,因团体操宏大精美的表演形式受到斯拉夫国家政府的高度重视,并大力推广。这种宏大精美的表演形式被奥运会开幕式、国家纪念日以及国家级会议的开幕式或晚宴所运用,而成为世界范围内的仪式表演。团体操表演是通过对手段要素的选择、重组,形成特定图案,这一特定图案用于彰显人性中的正能量,即对生命的礼赞。礼赞的对象,称为团体操文化、艺术功能。团体操的文化、艺术功能是,完成民族文化符号的展示、完成民族命运密码的展示和完成主题的展示。     

Where policy meets the pavement: Stages of public involvement in the prevention of school violence

Based on qualitative research on school and city violence, this article examines three forms of partnerships between community organizations and schools, including youth interventions by social services; community activism; and school liaisons with the police. The article examines how violence-prevention strategies are conceived within a context that includes the formation of policy directed at communities, youths, and schools; social science theories of delinquency; public rhetoric about youth and families; and efforts on the part of community residents, city departments, and social services. The underlying theory-base behind the research can be associated with cultural studies, since it combines cultural and structural interpretations of the topic and analyzes policies according to their processes, in light of their constructions, and in connection with the theories that guide them. It becomes obvious by the end of the article that community-based violence-prevention organizations collaborating with schools are sometimes blocked from doing good work by poor funding, power struggles, and a deficit model of youth. While the partnerships can, at times, help to initiate positive involvement of disenfranchised people, they can also become instruments of city power structures. For their positive and productive work to come out, the interagency and school collaborations must solve the problems that are discussed in the article.     

RFID: A New Technology in Library Management Systems

RFID is an acronym that stands for the radio frequency identification. RFID uses wireless radio communications for unique identification of people or assets. This article explains the technology, how RFID tags work, and, more important, their various uses in libraries.
