Light weight analysis of a skeleton vehicle frame using BS960 super-high-strength steel

Static strength finite element analysis was conducted to decrease the weight of a skeleton vehicle＇s frame. Results indicated that the maximum stress occurs on the front beam ＇s variable section area. Dynamic sensitivity analysis elucidated the relationship between the maximum stress and the thickness of a particular beam,e. g.,top,middle,and bottom beam. Displacement was analyzed by the key part that influenced the maximum stress. Finally,the new plan using BS960 super-high-strength beam steel and the preferred beam thickness was compared with the original plan. New combinations of beam thickness were introduced on the basis of different purposes; the maximum responding light w eight ratio was 21%.

FRAME MULTIRESOLUTION ANALYSIS AND INFINITE TREES IN BANACH SPACES ON LOCALLY COMPACT ABELIAN GROUPS

We extend the concept of frame multiresolution analysis to a locally compact abelian group and use it to define certain weighted Banach spaces and the spaces of their antifunctionals. We define analysis and synthesis operators on these spaces and establish the continuity of their composition. Also, we prove a general result to characterize infinite trees in the above Banach spaces of antifunctionals. This paper paves the way for the study of corresponding problems associated with some other types of Banach spaces on locally compact abelian groups including modulation spaces.

Television News Coverage of Obesity in China,1982-2009

Objective The purpose of this study was to explore how obesity was covered in television news in China, including the trends over time and the characteristics of obesity-related news. Methods The frame analysis was adopted to assess the content of obesity-related news broadcasted in China Central Television （CCTV） from 1982 to 2009. To investigate the characteristics of the news, the obesity-related news was divided into subgroups according to populations concerned, as well as the period in which the news was broadcasted. The differences between subgroups were examined. Results A total of 1 599 pieces of news reported obesity, in which 1 278 pieces （79.92%） aired in ＂wealthy＂ period （2006-2009）. More news was concerned with adults （1 134, 70.92%）. ＂Individual behavior＂ dominated most of the cause frames （389, 24.33%）, solution frames （522, 32.65%）, and responsibility frames （860, 53.78%）. There was more news mentioning individual factors in news aired in ＂wealthy＂ period and news concerning children. The coverage of social-structure causes was higher in news concerning children, while the coverage of social-structure solutions was higher in news concerning children and news aired in ＂wealthy＂ period. Conclusion Although the coverage of obesity was modest, it showed an incremental trend as the economy grew. Obesity was mostly depicted as an individual problem in terms of responsibility, causes and solutions.

Defining the Iraq-Afghanistan Veteran in American Newspapers

Employing inductive framing analysis and Entman＇s theory of framing, this project examines how the U.S. mainstream media defined Iraq-Afghanistan Veterans and their problems. This study used inductive framing analysis with a sample of 180 articles from seven major newspapers and two wire services. The findings revealed five dominant frames： broken veteran, disoriented veteran, fighting the bureaucratic enemy, overwhelmed family, and the financial hardship frames. Two counter-frames that attempted to challenge the dominant frames were identified： moral obligation to help and the healing counter-frames. The finding of this research indicates that while news frames of Iraq-Afghanistan Veterans skew negative, these news frames are not as negative as one might suspect. Thus, veterans＇ groups, government agencies, and interested political actors need to sponsor counter-frames that emphasize the stability and employability of these veterans.

Framing and Reframing the Digital Divide Policy in Taiwan： Consensus and Conflict

This paper explores key policy issues of national information and communication technology development to identify the gap between the heterogeneity in issues pertaining to the ＂digital divide＂. How this issue is cast often as a problem to be solved in recent years. On the public policy front, a series of reports issued by Taiwan Residents policymakers were endeavored to address universal services and digital divide issues. Government also has taken various steps to mitigate the disparity in opportunities to access the Internet （e.g., ＂e-Taiwan＂ for broadband services, ＂M-Taiwan＂ for broadband infrastructure and heterogeneous network services, and ＂i-Taiwan＂ for ubiquitous networks and digital convergence by Taiwan＇s Cabinet）. However, when policymakers worked to craft solutions to the pressing societal concern, they found lots of policy agendas need to redefine to foster greater understanding and enlighten practice for policy going forward. An examination of conflicting narratives within policy has been conducted, which identified not only the earlier debates were framed, but also key agendas of the most studied and empirical data used among them. The article attempts to examine the topic from a longitudinal perspective by using sets of documents revealed a tendency over time to explore how particular the agendas and debates of ＂digital divide＂ were framed. The study traced back to policy debates from cultural, economic, educational, and political perspectives at various Internet diffusion stages. The results provide useful insights into the study and discussion on new convergence policy making implications.
