CMAP

This document specifies a Connection Management Access Protocol (CMAP) for call management in high-speed packet switched networks. We target CMAP to networks employing the Asynchronous Transfer Mode (ATM) communication standard. CMAP specifies the access procedues exercised by network clients to manipulate multipoint calls; it is thus a User-Network Interface (UNI) signalling protocol. We define a multipoint call as a group of multipoint connections. A multipoint connection is a communication channel between two or more clients or endpoints of the network, where all data sent by one client is received by all other clients who have elected to receive. A point-to-point connection is a special case of a multipoint connection involving only two clients. CMAP provides facilities to create, modify, and delete calls, connections, and endpoints. Once a connection is established, clients exchange data using ATM data-transfer protocols that are specified separately from CMAP

Feasibility Assessment of the Reebok CHECKLIGHT™ and King-Devick tests as Screening tools in Youth Football

Background: Concussions are one of the foremost issues in sport, with football having one of the highest incidence rate of injury. Moreover, there is a need to monitor sub-concussive head impacts because they do not initiate further assessment which may increase an athlete’s risk of suffering a brain injury. The purpose of this article is to discuss the viability of use for the Reebok CHECKLIGHT™ system and its correlation to concussive events screening in two levels of football: youth recreation league football (ages 11-13) and high school football (ages 13-18). Results: The Reebok CHECKLIGHT™ system activation did not correlate with the King-Devick score (r=-0.08, p=0.7). There was no difference between the two levels of football in the number of times the lights came on, 1.77 ± 2.05 vs. 1.42 ± 0.79, p=0.57.Limitation: The viability of CHECKLIGHT™ system was limited by threshold issues with the light alert system, light usefulness, set-up, and implementation. Conclusion: The Reebok CHECKLIGHT™ system may be beneficial to individual athletes below the high school level; however, it appears to have limited usefulness for entire teams and/or high school athletes

Perceptual Annotation: Measuring Human Vision to Improve Computer Vision

For many problems in computer vision, human learners are considerably better than machines. Humans possess highly accurate internal recognition and learning mechanisms that are not yet understood, and they frequently have access to more extensive training data through a lifetime of unbiased experience with the visual world. We propose to use visual psychophysics to directly leverage the abilities of human subjects to build better machine learning systems. First, we use an advanced online psychometric testing platform to make new kinds of annotation data available for learning. Second, we develop a technique for harnessing these new kinds of information – “perceptual annotations” – for support vector machines. A key intuition for this approach is that while it may remain infeasible to dramatically increase the amount of data and high-quality labels available for the training of a given system, measuring the exemplar-by-exemplar difficulty and pattern of errors of human annotators can provide important information for regularizing the solution of the system at hand. A case study for the problem face detection demonstrates that this approach yields state-ofthe- art results on the challenging FDDB data set.Engineering and Applied SciencesMolecular and Cellular Biolog

The Washington University Multimedia System

The Washington University Multimedia System (MMS) is a complete multimedia system capable of transmitting and receiving video, audio, and radiological images, in addition to normal network traffic, over the Washingon University broadband ATM network. The MMS consists of an ATMizer and three multimedia subsystems. The ATMizer implements the host interface, the interface to the ATM network, and the interface to the three multimedia subsystems. The video sybsystem encodes and decodes JPEG compressed video using two hardware compression engines. The audio subsystem encodes and decodes CD-quality stereo audio. The high-speed radiological image subsystem reformats radiological image data transmitted by a dedicated ATMizer for presentation on a high-resolution monochrome display. Although the MMS can be easily modified to operate with any host, the current implementation is based on a NeXT computer. This paper describes the architecture of the MMS, the software used with the system, and the applications which have been developed to demonstrate the capability and applicability of broadband ATM networks for multimedia applications

Psychosocial risk assessment in organizations: concurrent validity of the brief version of the Management Standards Indicator Tool

The Management Standards Indicator Tool (MSIT) is a 35-item self-report measure of the psychosocial work environment designed to assist organizations with psychosocial risk assessment. It is also used in work environment research. Edwards and Webster presented a 25-item version of the MSIT based on the deletion of items having a factor loading of < .65. Stress theory and research suggest that psychosocial hazard exposures may result in harm to the health of workers. Thus, using data collected from three UK organizations (N = 20,406) we compared the concurrent validity of the brief and full versions of the MSIT by exploring the strength of association between each version of the instrument and a measure of psychological wellbeing (GHQ-12 and Maslach Burnout Inventory). Analyses revealed that the brief instrument offered similar but not always equal validity to that of the full version. The results indicate that use of the brief instrument, which would be less disruptive for employees, would not elevate the risk of false negative or false positive findings in risk assessment

Young children's interpersonal trust consistency as a predictor of future school adjustment

Young children’s interpersonal trust consistency was examined as a predictor of future school adjustment. One hundred and ninety two (95 male and 97 female, M age = 6 years 2 months, SD age = 6 months) children from school years 1 and 2 in the United Kingdom were tested twice over one-year. Children completed measures of peer trust and school adjustment and teachers completed the Short-Form Teacher Rating Scale of School Adjustment. Longitudinal quadratic relationships emerged between consistency of children’s peer trust beliefs and peer-reported trustworthiness and school adjustment and these varied according to social group, facet of trust, and indictor of school adjustment. The findings support the conclusion that interpersonal trust consistency, especially for secret-keeping, predicts aspects of young children’s school adjustment
