Holistic Responses to Campus Violence in the United States: Understanding the Needs of Campus and Community - Based Service Providers--RESEARCH
Campus violence is a significant social and public health problem in the United States and poses a unique situation for service provision. Victims often have access to both campus-based and community-based services, as they are simultaneously students and citizens of a larger community. Therefore, understanding the needs of campus violence service providers is essential for enhancing responses to campus violence. This research identifies knowledge and service delivery needs among service providers to support a comprehensive approach to ending campus violence. Situated in the social-ecological model, this article discusses the results of a survey to identify knowledge and service delivery needs among campus-and community-based service providers. The results indicate that both campus and community-based service providers were knowledgeable about campus violence and expressed confidence in providing services. However, clear areas for improving service providers’ knowledge base emerge, such as providing community-based service providers with a better understanding of campus judicial policies and campus-based responses to violence. Therefore, two recommendations for campus-based anti-violence efforts emerge. First, it is important for campus-based programs to provide broad training for the multiple service-provider constituents. Secondly, knowledge and service needs assessments can illuminate areas for additional training specific to constituencies

Web-based multimodal graphs for visually impaired people
This paper describes the development and evaluation of Web-based multimodal graphs designed for visually impaired and blind people. The information in the graphs is conveyed to visually impaired people through haptic and audio channels. The motivation of this work is to address problems faced by visually impaired people in accessing graphical information on the Internet, particularly the common types of graphs for data visualization. In our work, line graphs, bar charts and pie charts are accessible through a force feedback device, the Logitech WingMan Force Feedback Mouse. Pre-recorded sound files are used to represent graph contents to users. In order to test the usability of the developed Web graphs, an evaluation was conducted with bar charts as the experimental platform. The results showed that the participants could successfully use the haptic and audio features to extract information from the Web graphs
Отказоустойчивый многофазный асинхронный электропривод с несинусоидальными токами
Рассмотрен принцип построения многофазного асинхронного электропривода, позволяющего при неоднократных отказах преобразователя частоты и двигателя обеспечить отказоустойчивое управление, на основе программируемых несинусоидальных токов с восстановлением работоспособности за счет активизации алгоритма восстановления в управляющем микроконтроллере. Приведены результаты моделирования для аварийной ситуации типа "обрыв фазы" для случая трехфазного двигателя с частичным восстановлением работоспособности асинхронного двигателя
Constrained by managerialism : caring as participation in the voluntary social services
The data in this study show that care is a connective process, underlying and motivating participation and as a force that compels involvement in the lives of others, care is at least a micro-participative process. Care or affinity not only persisted in the face of opposition, but it was also used by workers as a counter discourse and set of practices with which to resist the erosion of worker participation and open up less autonomized practices and ways of connecting with fellow staff, clients and the communities they served. The data suggest that while managerialism and taylorised practice models may remove or reduce opportunities for worker participation, care is a theme or storyline that gave workers other ways to understand their work and why they did it, as well as ways they were prepared to resist managerial priorities and directives, including the erosion of various kinds of direct and indirect participation. The degree of resistance possible, even in the highly technocratic worksite in Australia, shows that cracks and fissures exist within managerialism
Parameterized Verification of Safety Properties in Ad Hoc Network Protocols
We summarize the main results proved in recent work on the parameterized
verification of safety properties for ad hoc network protocols. We consider a
model in which the communication topology of a network is represented as a
graph. Nodes represent states of individual processes. Adjacent nodes represent
single-hop neighbors. Processes are finite state automata that communicate via
selective broadcast messages. Reception of a broadcast is restricted to
single-hop neighbors. For this model we consider a decision problem that can be
expressed as the verification of the existence of an initial topology in which
the execution of the protocol can lead to a configuration with at least one
node in a certain state. The decision problem is parametric both on the size
and on the form of the communication topology of the initial configurations. We
draw a complete picture of the decidability and complexity boundaries of this
problem according to various assumptions on the possible topologies.Comment: In Proceedings PACO 2011, arXiv:1108.145
Magnetic dipole moment of the in chiral perturbation theory
The magnetic dipole moment of the is calculated in the
framework of manifestly Lorentz-invariant baryon chiral perturbation theory in
combination with the extended on-mass-shell renormalization scheme. As in the
case of the nucleon, at leading order both isoscalar and isovector anomalous
magnetic moments are given in terms of two low-energy constants. In contrast to
the nucleon case, at next-to-leading order the isoscalar anomalous magnetic
moment receives a (real) loop contribution. Moreover, due to the unstable
nature of the , at next-to-leading order the isovector anomalous
magnetic moment not only receives a real but also an imaginary loop
contribution.Comment: 9 pages, 2 figures, REVTeX
