Educational technology applications and lessons, such as learning modules, activities, and user-authored systems, face substantial implementation challenges in public schools and postsecondary institutions. The design of technology impacts the willingness of teachers to implement new technology; evaluators examining implementation obstacles can help improve design. In this article, both summati...

OBJECTIVES The aim of this study was to investigate the concurrent validity of the Smart Balance Master (SBM) tests in individuals with incomplete spinal cord injury. DESIGN Correlational study. SUBJECTS A total of 32 individuals with an American Spinal Injury Association Impairment Scale D spinal cord injury able to walk 10 m independently, with or without walking assistive devices. METH...

BACKGROUND Motor neurone disease (MND) is a progressive neurological disease causing muscle wasting, gradual paralysis, respiratory failure. MND care is demanding, complex and involves a variety of care tasks. Family members may experience significant and enduring strain. We conducted a qualitative study to understand more about family caregivers' work and sense of responsibility, exploring fam...

Multi-agent systems raise many new and interesting research issues in AI-based educational collaborative systems. Some of those issues relate to the user model. When many agents inhabit a system, they must cooperate in their agent society, interacting with each other. They must interact with the world outside the computer (i.e. with the learners). They must have adequate knowledge of the users ...

PURPOSE Being bullied is associated with the manifestation of suicidal feelings, which sharply increase in middle(-late) adolescence. Whether or not bullied middle(-late) adolescents with suicidal feelings seek help is therefore a critical issue, given that help-seeking plays a key role in the prevention of suicide. The aim of the present study is to investigate the effects of bullying, suicida...

The gauge coupling constant unification at the low (O(TeV)) scale can be obtained just in four dimensions, without help of the power like renormalization group evolution in extra dimensions, due to the presence of some extra particle states at intermediate scales. We show explicit examples of such extra states in the range of 100 GeV – 1 TeV which can be easily observed on future colliders and ...

as we know oxygen is one of the main inhibitors of polymerization of vinyl acetate. therefore, nitrogen is used in order to make sure of system's high purity. to maintain purity it is necessary to find out the rate of the oxygensolution in polymerization system under different conditions of polymerization. it is concluded that incoming nitrogen to the system would remove the oxygen from th...

OBJECTIVE The purpose of this study was to describe, qualitatively the use of service dogs by persons with physical disabilities and the meaning of this experience. METHOD Five service dog owners were observed and interviewed on multiple occasions through an ethnographic approach. RESULTS Identified themes were increased community participation, "closer than family" increased social contact...

A field experiment was performed to investigate the effect of several variables on helping behavior, using the express trains of the New York 8th Avenue Independent Subway as a laboratory on wheels. Four teams of students, each one made up of a victim, model, and two observers, staged standard collapses in which type of victim (drunk or ill), race of victim (black or white) and presence or abse...
