Service user involvement in drug treatment programs: Barriers to implementation and potential benefits for client recovery

Service user forums have the potential for improving awareness of services, empowering service users and strengthening community partnerships within an inclusive treatment and rehabilitation framework. The research aimed to investigate perspectives about service user involvement in order to inform the development of effective service user forum(s) in west Ireland. A total of 30 interviews with key service providers and 12 interviews with service users were conducted, with interview questions focusing on: (1) awareness of the Service User Support Team and (2) barriers to service user involvement and the development of service user forums in the region. An integrated data collection and thematic analysis was undertaken. Current levels of service user involvement were low, restricted by one-way communication and appeared grounded in user-provider power differentials and stigma relating to drug dependency. Service providers queried the actual terms of reference, capacity and training that would be needed for service user forums to advocate and lobby for service users. The use of existing support groups, creation of internet user forums and rotation of rural meetings were recommended to promote engagement among service users. The research underscores the need for transparency, resources and a framework for good practice that reflects a participatory approach

Service user involvement in teaching about conflict - an exploration of the issues

Service user involvement is now a well embedded feature of social work
education in the United Kingdom. Whilst many education institutions have
fully embraced the involvement of service users in teaching, there is still
work to be done in more fully engaging with service users who are seldom
heard. This article highlights the opportunities and challenges associated
with innovative work being piloted in Northern Ireland where victims and
survivors of political conflict are routinely involved in teaching social work
students about the impact of conflict on their lives.

m-SportGIS

Information technologies (ITs), and sports resources and services aid the potential to transform governmental organizations, and play an important role in contributing to sustainable communities development, respectively. Spatial data is a crucial source to support sports planning and management. Low-cost mobile geospatial tools bring productive and accurate data collection, and their use combining a handy and customized graphical user interface (GUI) (forms, mapping, media support) is still in an early stage. Recognizing the benefits — efficiency, effectiveness, proximity to citizens — that Mozambican Minister of Youth and Sports (MJD) can achieve with information resulted from the employment of a low-cost data collection platform, this project presents the development of a mobile mapping application (app) — m-SportGIS — under Open Source (OS) technologies and a customized evolutionary software methodology. The app development embraced the combination of mobile web technologies and Application Programming Interfaces (APIs) (e.g. Sencha Touch (ST), Apache Cordova, OpenLayers) to deploy a native-to-the-device (Android operating system) product, taking advantage of device’s capabilities (e.g. File system, Geolocation, Camera). In addition to an integrated Web Map Service (WMS), was created a local and customized Tile Map Service (TMS) to serve up cached data, regarding the IT infrastructures limitations in several Mozambican regions. m-SportGIS is currently being exploited by Mozambican Government staff to inventory all kind of sports facilities, which resulted and stored data feeds a WebGIS platform to manage Mozambican sports resources.

The DIADEM Software Development Methodology extended to Multimedia Interfaces

DIADEM, created by THOMSON-CSF, is a methodology for specifying and developing user interfaces. It improves productivity of the interface development process as well as quality of the interface. The method provides support to user interface development in three aspects. (1) DIADEM defines roles of people involved and their tasks and organises the sequence of activities. (2) It provides graphical formalisms supporting information exchange between people. (3) It offers a basic set of rules for optimum human-machine interfaces. The use of DIADEM in three areas (process control, sales support, and multimedia presentation) was observed and evaluated by our laboratory in the European project DIAMANTA (ESPRIT P20507). The method provides an open procedure that leaves room for adaptation to a specific application and environment. This paper gives an overview of DIADEM and shows how to extend formalisms for developing multimedia interfaces.

Norms-based simulation for personalised service provision

User interfaces have the primary role of enabling access to information meeting individual users' needs. However, the user-systems interaction is still rigid, especially in support of complex environments where various types of users are involved. Among the approaches for improving user interface agility, we present a normative approach to the design interfaces of web applications, which allow delivering users personalized services according to parameters extracted from the simulation of norms in the social context. A case study in an e-Government context is used to illustrate the implications of the approach.

Perspex machine X: software development

The Perspex Machine arose from the unification of computation with geometry. We now report significant redevelopment of both a partial C compiler that generates perspex programs and of a Graphical User Interface (GUI). The compiler is constructed with standard compiler-generator tools and produces both an explicit parse tree for C and an Abstract Syntax Tree (AST) that is better suited to code generation. The GUI uses a hash table and a simpler software architecture to achieve an order of magnitude speed up in processing and, consequently, an order of magnitude increase in the number of perspexes that can be manipulated in real time (now 6,000). Two perspex-machine simulators are provided, one using trans-floating-point arithmetic and the other using transrational arithmetic. All of the software described here is available on the world wide web. The compiler generates code in the neural model of the perspex. At each branch point it uses a jumper to return control to the main fibre. This has the effect of pruning out an exponentially increasing number of branching fibres, thereby greatly increasing the efficiency of perspex programs as measured by the number of neurons required to implement an algorithm. The jumpers are placed at unit distance from the main fibre and form a geometrical structure analogous to a myelin sheath in a biological neuron. Both the perspex jumper-sheath and the biological myelin-sheath share the computational function of preventing cross-over of signals to neurons that lie close to an axon. This is an example of convergence driven by similar geometrical and computational constraints in perspex and biological neurons.

Goals Software Construction Process

Generalized hyper competitiveness in the world markets has determined the need to offer better products to potential and actual clients in order to mark an advantagefrom other competitors. To ensure the production of an adequate product, enterprises need to work on the efficiency and efficacy of their business processes (BPs) by means of the construction of Interactive Information Systems (IISs, including Interactive Multimedia Documents) so that they are processed more fluidly and correctly.The construction of the correct IIS is a major task that can only be successful if the needs from every intervenient are taken into account. Their requirements must bedefined with precision, extensively analyzed and consequently the system must be accurately designed in order to minimize implementation problems so that the IIS isproduced on schedule and with the fewer mistakes as possible. The main contribution of this thesis is the proposal of Goals, a software (engineering) construction process which aims at defining the tasks to be carried out in order to develop software. This process defines the stakeholders, the artifacts, and the techniques that should be applied to achieve correctness of the IIS. Complementarily, this process suggests two methodologies to be applied in the initial phases of the lifecycle of the Software Engineering process: Process Use Cases for the phase of requirements, and; MultiGoals for the phases of analysis and design. Process Use Cases is a UML-based (Unified Modeling Language), goal-driven and use case oriented methodology for the definition of functional requirements. It uses an information oriented strategy in order to identify BPs while constructing the enterprise’s information structure, and finalizes with the identification of use cases within the design of these BPs. This approach provides a useful tool for both activities of Business Process Management and Software Engineering. MultiGoals is a UML-based, use case-driven and architectural centric methodology for the analysis and design of IISs with support for Multimedia. It proposes the analysis of user tasks as the basis of the design of the: (i) user interface; (ii) the system behaviour that is modeled by means of patterns which can combine Multimedia and standard information, and; (iii) the database and media contents. This thesis makes the theoretic presentation of these approaches accompanied with examples from a real project which provide the necessary support for the understanding of the used techniques.

Desenvolvimento de Interface gráfica como suporte para soluções numéricas das equações de Maxwell em coordenadas gerais – 3D

Neste trabalho, é implementada uma interface gráfica de usuários (GUI) usando a ferramenta Qt da Nokia (versão 3.0). A interface visa simplificar a criação de cenários para a realização de simulações paralelas usando a técnica numérica Local Nonorthogonal Finite Difference Time-Domain (LN-FDTD), aplicada para solucionar as equações de Maxwell. O simulador foi desenvolvido usando a linguagem de programação C e paralelizado utilizando threads. Para isto, a biblioteca pthread foi empregada. A visualização 3D do cenário a ser simulado (e da malha) é realizada por um programa especialmente desenvolvido que utiliza a biblioteca OpenGL. Para melhorar o desenvolvimento e alcançar os objetivos do projeto computacional, foram utilizados conceitos da Engenharia de Software, tais como o modelo de processo de software por prototipagem. Ao privar o usuário de interagir diretamente com o código-fonte da simulação, a probabilidade de ocorrência de erros humanos durante o processo de construção de cenários é minimizada. Para demonstrar o funcionamento da ferramenta desenvolvida, foi realizado um estudo relativo ao efeito de flechas em linhas de baixa tensão nas tensões transitórias induzidas nas mesmas por descargas atmosféricas. As tensões induzidas nas tomadas da edificação também são estudadas.

GEDI: a user-friendly toolbox for analysis of large-scale gene expression data

Abstract Background Several mathematical and statistical methods have been proposed in the last few years to analyze microarray data. Most of those methods involve complicated formulas, and software implementations that require advanced computer programming skills. Researchers from other areas may experience difficulties when they attempting to use those methods in their research. Here we present an user-friendly toolbox which allows large-scale gene expression analysis to be carried out by biomedical researchers with limited programming skills. Results Here, we introduce an user-friendly toolbox called GEDI (Gene Expression Data Interpreter), an extensible, open-source, and freely-available tool that we believe will be useful to a wide range of laboratories, and to researchers with no background in Mathematics and Computer Science, allowing them to analyze their own data by applying both classical and advanced approaches developed and recently published by Fujita et al. Conclusion GEDI is an integrated user-friendly viewer that combines the state of the art SVR, DVAR and SVAR algorithms, previously developed by us. It facilitates the application of SVR, DVAR and SVAR, further than the mathematical formulas present in the corresponding publications, and allows one to better understand the results by means of available visualizations. Both running the statistical methods and visualizing the results are carried out within the graphical user interface, rendering these algorithms accessible to the broad community of researchers in Molecular Biology.

Gestión de pacientes de un Servicio de Urgencias Hospitalarias

[ES] Un servicio de urgencias de una zona ofrece asistencia sanitaria y tiene como principal objetivo atender la patología urgente que acude al hospital y el nivel de compromiso que se asume consiste en diagnosticar, tratar y estabilizar, en la medida posible, dicha patología urgente. Otro objetivo es gestionar la demanda de atención urgente por parte del ciudadano a través de un sistema de selección prioritaria inicial (Triaje) que selecciona, prioriza, organiza y gestiona la demanda de atención. Para poder controlar y realizar el trabajo de la forma más eficaz se utilizan herramientas de gestión necesarias para el control de los pacientes, desde que se realiza su ingreso en el servicio de urgencias hasta el alta del mismo. Las aplicaciones desarrolladas son las siguientes: Gestión de Pacientes en Urgencias: Esta aplicación asignará un estado inicial al paciente y permitirá ir cambiando el estado del mismo usando el método del Triaje (valoración), el más difundido en la medicina de urgencias. Además, se podrán solicitar pruebas diagnósticas y la visualización de marcadores de analíticas para comprobar su evolución. Finalmente, se podrá desarrollar un informe de alta para el paciente. Informadores de Urgencias: La aplicación gestiona la localización física del paciente dentro del servicio de urgencias, permitiendo asimismo el cambio entre las distintas localizaciones y el control para la información a los familiares de los mismos, pudiendo almacenar los familiares y teléfonos de contactos para que estos puedan ser informados. El desarrollo se ha realizado utilizando el MVC (modelo - vista - controlador) que es patrón de arquitectura que separa los datos de una aplicación, la interfaz gráfica de usuario y la lógica de control de componentes. El software utilizado para el desarrollo de las aplicaciones es CACHÉ de Intersystems que permite la creación de una base de datos multidimensional. El modelo de objetos de Caché se basa en el estándar ODMG (Object Database Management Group, Grupo de gestión de bases de datos de objetos) y soporta muchas características avanzadas. CACHÉ dispone de Zen, una biblioteca completa de componentes de objetos preconstruidos y herramientas de desarrollo basadas en la tecnología CSP (Caché Server Pages) y de objetos de InterSystems. ZEN es especialmente apropiado para desarrollar una versión Web de las aplicaciones cliente/servidor creadas originalmente con herramientas como Visual Basic o PowerBuilder.

Semi-Automated Creation of Converged iTV Services: From Macromedia Director Simulations to Services Ready for Broadcast

While sound and video may capture viewers' attention, interaction can captivate them. This has not been available prior to the advent of Digital Television. In fact, what lies at the heart of the Digital Television revolution is this new type of interactive content, offered in the form of interactive Television (iTV) services. On top of that, the new world of converged networks has created a demand for a new type of converged services on a range of mobile terminals (Tablet PCs, PDAs and mobile phones). This paper aims at presenting a new approach to service creation that allows for the semi-automatic translation of simulations and rapid prototypes created in the accessible desktop multimedia authoring package Macromedia Director into services ready for broadcast. This is achieved by a series of tools that de-skill and speed-up the process of creating digital TV user interfaces (UI) and applications for mobile terminals. The benefits of rapid prototyping are essential for the production of these new types of services, and are therefore discussed in the first section of this paper. In the following sections, an overview of the operation of content, service, creation and management sub-systems is presented, which illustrates why these tools compose an important and integral part of a system responsible of creating, delivering and managing converged broadcast and telecommunications services. The next section examines a number of metadata languages candidates for describing the iTV services user interface and the schema language adopted in this project. A detailed description of the operation of the two tools is provided to offer an insight of how they can be used to de-skill and speed-up the process of creating digital TV user interfaces and applications for mobile terminals. Finally, representative broadcast oriented and telecommunication oriented converged service components are also introduced, demonstrating how these tools have been used to generate different types of services.

How to Improve the Production Process for interactive TV with semi-formal Methods

The central question for this paper is how to improve the production process by closing the gap between industrial designers and software engineers of television(TV)-based User Interfaces (UI) in an industrial environment. Software engineers are highly interested whether one UI design can be converted into several fully functional UIs for TV products with different screen properties. The aim of the software engineers is to apply automatic layout and scaling in order to speed up and improve the production process. However, the question is whether a UI design lends itself for such automatic layout and scaling. This is investigated by analysing a prototype UI design done by industrial designers. In a first requirements study, industrial designers had created meta-annotations on top of their UI design in order to disclose their design rationale for discussions with software engineers. In a second study, five (out of ten) industrial designers assessed the potential of four different meta-annotation approaches. The question was which annotation method industrial designers would prefer and whether it could satisfy the technical requirements of the software engineering process. One main result is that the industrial designers preferred the method they were already familiar with, which therefore seems to be the most effective one although the main objective of automatic layout and scaling could still not be achieved.

Software als Schutzgegenstand des Europäischen Urheberrechts

After 20 years of silence, two recent references from the Czech Republic (Bezpečnostní softwarová asociace, Case C-393/09) and from the English High Court (SAS Institute, Case C-406/10) touch upon several questions that are fundamental for the extent of copyright protection for software under the Computer Program Directive 91/25 (now 2009/24) and the Information Society Directive 2001/29. In Case C-393/09, the European Court of Justice held that “the object of the protection conferred by that directive is the expression in any form of a computer program which permits reproduction in different computer languages, such as the source code and the object code.” As “any form of expression of a computer program must be protected from the moment when its reproduction would engender the reproduction of the computer program itself, thus enabling the computer to perform its task,” a graphical user interface (GUI) is not protected under the Computer Program Directive, as it does “not enable the reproduction of that computer program, but merely constitutes one element of that program by means of which users make use of the features of that program.” While the definition of computer program and the exclusion of GUIs mirror earlier jurisprudence in the Member States and therefore do not come as a surprise, the main significance of Case C-393/09 lies in its interpretation of the Information Society Directive. In confirming that a GUI “can, as a work, be protected by copyright if it is its author’s own intellectual creation,” the ECJ continues the Europeanization of the definition of “work” which began in Infopaq (Case C-5/08). Moreover, the Court elaborated this concept further by excluding expressions from copyright protection which are dictated by their technical function. Even more importantly, the ECJ held that a television broadcasting of a GUI does not constitute a communication to the public, as the individuals cannot have access to the “essential element characterising the interface,” i.e., the interaction with the user. The exclusion of elements dictated by technical functions from copyright protection and the interpretation of the right of communication to the public with reference to the “essential element characterising” the work may be seen as welcome limitations of copyright protection in the interest of a free public domain which were not yet apparent in Infopaq. While Case C-393/09 has given a first definition of the computer program, the pending reference in Case C-406/10 is likely to clarify the scope of protection against nonliteral copying, namely in how far the protection extends beyond the text of the source code to the design of a computer program and where the limits of protection lie as regards the functionality of a program and mere “principles and ideas.” In light of the travaux préparatoires, it is submitted that the ECJ is also likely to grant protection for the design of a computer program, while excluding both the functionality and underlying principles and ideas from protection under the European copyright directives.
