A mathematical model of a 2D homogeneous swarm of robots

We present a simulation of the behavior of a homogeneous group of robots in an environment with obstacles. The problems of 2D flight of robots to different target objects were considered. The questions of the mutual dependence between local control rules and global adaptive group behavior and the synthesis of group control were studied and an analysis of the controllability of the group targets in environment with obstacles was performed. The results of the simulation are presented and examples of the operation of the simulation program are given.     

Lesbian, gay, bisexual, and transgender health issues, disparities, and information resources

Lesbian, gay, bisexual, and transgender (LGBT) persons, while widely diverse in many ways, share health disparities related to the stigma and discrimination they experience, including disproportionate rates of psychiatric disorders, substance abuse, and suicide. Lesbians, gay men, bisexuals, and the transgender communities have additional health concerns and disparities unique to each population. This paper highlights the national recognition of these health issues and disparities and presents web-based information resources about them and their mitigation.

Television,Japan, and Globalization

Prime-time network programs broadcast between 7 993 and 2002 underrepresent elderly characters. More women between the ages of 50 and 64 were classified as elderly, rather than middle-aged. The age distribution of minority men resembles that of White women, while minority women are typically cast in younger age groups. The world of work on television is one of diminished options for the elderly. Television celebrates youth while it neglects and negates the elderly.     

Promise,Perils, and Planning

Summary

The promising future of new and better information services supported by the use of information technologies is well documented. Many journal articles describe successful experiences with better reference and instructional services, new services to new kinds of students who are engaged in distant independent learning or other non-traditional education, and better communication with library users. However, there are many perils on the way to delivering such improvements with the use of new finding tools, new software, new printing systems, and new telecommunication networks. An administrative overview of the sorts of planning which can smooth the implementation of information technology-based reference and instructional services outlines options for staffing, troubleshooting, fund raising, and budget development. Planning takes time and effort, collaboration and creativity. With appropriate emphasis on planning, the promise of implementing improvements in quality of services through information technologies can and should become a reality.     

Culture,Creativity, and Research

This article charts the increasing importance of the creative industries to the UK economy and to ways of meeting the information needs of those industries. The role of libraries is examined, particularly that of the British Library and its support services for business and enterprise. Related issues are discussed, such as those relating to the measurement of the value of services like the British Library, the preservation of digital documentation, and heritage and intellectual property rights.     

Empiricism,paradigms, and data

Rather than being based on an indefensible distinction between empiricists and interpretivists, this essay argues that such a distinction, although generally held by many persons, is actually not defensible on the basis of a supposed theory–data interaction. Covering law explanations are not part of common theory in communication research. Paradigmatic distinctions are typically thought of as being fundamental to the point of irresolvable, and when they are based on philosophical positions should be sharply questioned. Research is best performed when paradigms do not limit the activity or the thought of researchers.
