Research paper thumbnail of TakeCARE, a Video Bystander Program to Help Prevent Sexual Violence on College Campuses: Results of Two Randomized, Controlled Trials

Method: In Study 1, students were recruited from psychology courses at 2 universities. In Study 2, first-year students were recruited from a required course at 1 university. In both studies, students were randomly assigned to view 1 of 2 videos: TakeCARE or a control video on study skills. Just before viewing the videos, students completed measures of bystander behavior toward friends and ratings of self-efficacy for performing such behaviors. The efficacy measure was administered again after the video, and both the bystander behavior measure and the efficacy measure were administered at either 1 (Study 1) or 2 (Study 2) months later. Results: In both studies, students who viewed TakeCARE, compared with students who viewed the control video, reported engaging in more bystander behavior toward friends and greater feelings of efficacy for performing such behavior. In Study 1, feelings of efficacy mediated effects of TakeCARE on bystander behavior; this result did not emerge in Study 2. Conclusions: This research demonstrates that TakeCARE, a video bystander program, can positively influence bystander behavior toward friends. Given its potential to be easily distributed to an entire campus community, TakeCARE might be an effective addition to campus efforts to prevent sexual violence.

These architectures should react to events that occur simultaneously with eventual redundancy from different input media. In this paper, intelligent agent based generic architectures for multimedia multimodal dialog protocols are proposed. Global agents are decomposed into their relevant components. Each element is modeled separately using timed Colored Petri networks. The elementary models are then linked together to obtain the full architecture. The generic components of the application are then monitored by a based agent expert system to perform dynamic changes in reconfiguration, adaptation and evolution at the architectural level. For validation purpose, the proposed multi-agent architectures and its dynamic reconfiguration are respectively applied on practical examples.

The focus of the work in this paper is the application of agent-oriented software development methodologies to architecture enterprise modeling as well as the management of the variability guided by a strategic cost/schedule/quality or benefit/value/risk goals. This study will be the first step of working towards enabling tool support for enterprise variability management, enterprise modeling, validating and deducting the consequences of constrains or feature interactions in enterprise organization.

Some approaches can be followed to evaluate the quality of software, but gives no guidance on how to construct a high quality software product and on how to use in practice this model across evaluation process. IS are built upon Software, and the quality of Software effects, if not determine the quality of the IS. There are several difficulties of developing a comprehensive model of IS quality. The concepts, models and measures that work in other fields might be usefully applied to the IS field, but careful analysis and consideration should be given. This paper describes a practical method that can be used to evaluate the expected quality of IS. Our approach is focused on a direct evaluation of the quality of an IS. Our proposed IS quality model is considered as structured set of properties (such as reliability, maintainability, and so on). These properties are usually presented as a hierarchy of statements. The uppermost ones represent the most general properties, suitable to be understood by the widest variety of people, but very difficult to measure directly. The deeper we sink into this hierarchy, the more technical-audience-oriented and measurable properties are found. These finals properties need to be measured using metrics. For this purpose a metrics measurement-based framework is linked to the defined quality model.

Responding to industrial practice, in previous works we have proposed a semi-automatic bottom-up refactoring process to build RA from existing products; their architectures are represented by a connected graph or valid architectural configuration (P, R), where P and R represent components and connectors. In this paper, on one hand we formalize the existence of the Refactoring Graph (RG) automatically constructed for each product, as a main artefact of the process. On the other hand, this process is extended with a new subprocess to manually complete the candidate architecture (CA) obtained automatically, combining the ISO/IEC 25010 standard quality model and goal-oriented techniques to model also non-functional variability, which is still an open research issue in SPL. Finally, RA is manually constructed from the completed CA by generalizing the variants obtained. The complete extended refactoring process is applied to obtain RA for the Integrated Healthcare Systems (IHS) domain. The process is partially tool supported.

Nonfunctional properties play an important role, however methods are not still mature. We have defined a pattern-based architectural design method driven by quality properties. Our goal is to apply it to design a platform to model scientific calculation. We do not intend to re-write a new Simulation Code (Quantum Chemistry, Molecular Dynamics etc ...) nor to integrate various existing Codes inside an external envelope, with some scripting language, which is the usual practice in most of these calculation environments. Our intention is rather to spend the necessary time to design rationally the architecture and the objects of a modeling framework. In this platform the architecture is crucial to handle a unique calculation structure, shared by all the components of the platform.

These applications consist of a collection of interacting entities, either considered as subsystems, objects, components, or -more recently-web-services, that cooperate to provide some functionality.
