Sistema de sugestão de restaurantes

Actualmente assiste-se a uma difusão cada vez mais acentuada de dispositivos móveis multi-funções que incluem suporte para GPS (Global Positioning System). Outro fenómeno recente é a elevada aceitação dos serviços de rede social, que são cada vez mais numerosos e com objectivos diversificados. Alguns destes serviços de rede social disponibilizam APIs que permitem o acesso programático à informação nelescontida, viabilizando desse modo a adição de novas funcionalidades, bem como a utilização desta informação por aplicações externas. Aproveitando estes fenómenos, pretende-se implementar um sistema que permita ao utilizador obter no seu dispositivo móvel, de forma simples e imediata, sugestões de restaurantes mais próximos da sua localização actual. A lista de sugestões é elaborada tendo como base vários critérios, entre eles, a classificação dada pelos elementos da rede social em que o utilizador participe. Ambiciona-se utilização à escala mundial e consequentemente, pretende-se que o sistema tenha as características desejáveis num sistema distribuído de larga escala, i.e. escalabilidade e elevada disponibilidade. A solução Find-a-meal é um sistema de sugestão de restaurantes através do qual, especificando uma localização, são obtidas sugestões personalizadas com base nas preferências da rede social do utilizador. Este sistema foi desenhado para suportar o aumento de escala no sentido horizontal e ter elevada disponibilidade

Radiographic outcomes and evaluation of developmental dysplasia of the hip in children

The Developmental Dysplasia of the Hip (DDH), also know as Congenital Dislocation of the Hip, is common in infants and children and may persist into adulthood. The radiographic interpretation is highly conditioned by appropriate patient positioning and image quality criteria. The main goal of this study is to demonstrate the value of radiographic evaluation of DDH. Through the retrospective analysis of 65 radiographs of the hips, only 2 (3.1%) female patients with 1-2 years of age presented radiographic findings of DDH. The inappropriate field size and the improper placement and size of the gonadal shields, were the most common errors observed.

The use and relevance of gonad protection shields in children during hips radiography

Considering that ionizing radiation effects are cumulative and the gonads are particularly sensitive to these effects, and also the clinical importance of pelvic radiographs in children, the excess of radiation exposure to the gonads must be avoided. The purpose of this study is to demonstrate the relevance of the correct use of gonad protection shields and to evaluate their use on the hip radiographs performed in a reference clinical institution, through the retrospective analysis of pelvic radiographic images performed in children. According the image quality assessment, 20 (40%) patients were unprotected and gonads shields were incorrectly placed in 24 (80%) patients.

Avaliação radiológica do refluxo vesico – ureteral em crianças

O Refluxo Vesico – Ureteral (RVU) é uma patologia frequente na idade pediátrica. A detecção precoce de RVU é fundamental na orientação terapêutica, de modo a permitir um crescimento renal adequado e prevenir infecções urinárias recorrentes. A investigação radiológica de RVU baseia-se na ecografia e cistouretrografia miccional seriada (CUMS), sendo este último procedimento, o método de eleição, efectuado sob controlo fluoroscópico. Este trabalho tem como objectivo dar a conhecer o papel CUMS na avaliação de RVU e abordar os parâmetros técnicos de aquisição, posicionamento e critérios de qualidade de imagem.

Providing location everywhere

The ability to locate an individual is an essential part of many applications, specially the mobile ones. Obtaining this location in an open environment is relatively simple through GPS (Global Positioning System), but indoors or even in dense environments this type of location system doesn't provide a good accuracy. There are already systems that try to suppress these limitations, but most of them need the existence of a structured environment to work. Since Inertial Navigation Systems (INS) try to suppress the need of a structured environment we propose an INS based on Micro Electrical Mechanical Systems (MEMS) that is capable of, in real time, compute the position of an individual everywhere.

Ethical dilemmas in scientific publication: pitfalls and solutions for editors

Editors of scientific journals need to be conversant with the mechanisms by which scientific misconduct is amplified by publication practices. This paper provides definitions, ways to document the extent of the problem, and examples of editorial attempts to counter fraud. Fabrication, falsification, duplication, ghost authorship, gift authorship, lack of ethics approval, non-disclosure, 'salami' publication, conflicts of interest, auto-citation, duplicate submission, duplicate publications, and plagiarism are common problems. Editorial misconduct includes failure to observe due process, undue delay in reaching decisions and communicating these to authors, inappropriate review procedures, and confounding a journal's content with its advertising or promotional potential. Editors also can be admonished by their peers for failure to investigate suspected misconduct, failure to retract when indicated, and failure to abide voluntarily by the six main sources of relevant international guidelines on research, its reporting and editorial practice. Editors are in a good position to promulgate reasonable standards of practice, and can start by using consensus guidelines on publication ethics to state explicitly how their journals function. Reviewers, editors, authors and readers all then have a better chance to understand, and abide by, the rules of publishing.

Corporate brand identity – a conceptual redefinition

There is a wide agreement that identity is a multidisciplinary concept. Branding is an identity expression. Although there are some frameworks to assess brand identity there isn’t an accepted definition. The authors consider this a gap in literature and investigate the components to assess brand identity under a holistic approach. Literature was reviewed and reinterpreted under an integrated perspective evolving corporate and brand identity studies. The authors propose a definition and nine componentscharacterizing corporate brand identity: reputation, culture, positioning, personality, relationships network, presentation style, communication, environmental influences and mission. Some are related with internal and others to external facets. The authorsare strongly encouraged to test these results empirically towards validity and reliability of the proposed construct.

Identity – towards a conceptualization

The development of economical relations increases the interaction between organizations and stakeholders. It is no more acceptable to manage an organization under a transactional perspective where suppliers had a fundamental role. Nowadays organizations are being managed under a relational perspective where relations and relationship management in general have consequences in identity management (Hakansson e Snehota, 1989, 1995). A correct perception and management of identity is necessary to achieve distinctiveness in the competitive environment. This way, identity is influenced by relations with stakeholders in general and particularly with competitors. The ICIG concept states that identity is related with the values of the organization and it helps creating distinctiveness in the competitive environment (Van Riel, Balmer, 1997); Baker and Balmer (1997) state that identity is what the organization is; Suvatjis and de Chernatony (2005) refer that expressing identity is a dynamic process that evolves the use of a management model to face context changes; Kapferer (1991) states that brand identity is the project, the self conception of the brand. After reviewing and confronting literature under the plethora of identities’ concepts and perspectives (He, Balmer, 2007) one can’t find an integrative answer with all the elements that contribute to identity of organizations. The authors are strongly interested to contribute to the elimination of this limitation and to answer to strategic management needs. In a marketing context one can find: - the corporate identity approach that is focused in the distinctive attributes of an organization (Abratt, Balmer, Marwick e Fill, Stuart, Balmer and Gray, Alessandri, Suvatjis and de Chernatony) - the brand identity approach (related with the application of corporate identity studies to brands) - Kapferer, Semprini, Aaker, de Chernatony). Kapferer (1991), one of the most prolific authors in this field was the first author to integrate identity in a brand concept. In his view, identity is an emission concept. This idea is shared also by Aaker (1996). Yet, identity has to be managed in a competitive environment which is constantly changing. After reviewing and confronting literature, authors select concepts that are generally accepted by the investigators in order to design a model to analyze and manage identity: - corporate identity models: personality, image/reputation, culture, philosophy, mission, strategy, structure, communication - some of these concepts derive from identity models and others from identity management models; - brand identity models – Kapferer (1991, 2008) identity prism, witch is basis of literature in this field: culture, physical facet, personality, relationship (between brand and consumer), reflected consumer, consumers` self-concept. After discussion authors decide to include other concept in line with other authors` view: country of origin (Aaker, 1996). A discussion eliminates the twin concepts and the final selection is as follows: personality, image/reputation, culture (including philosophy and mission), strategy, structure, communication, culture, physical facet, relationship (between brand and consumer), reflected consumer, consumers` self-concept and according to authors` reflections “relationships” deriving from competitors` actions in competitive environment. Competitors’ actions and decisions have a stronger influence in the organizations` positioning than any other stakeholder as stated before. This is a work in progress towards a new model in identity analysis and management so an exploratory study will follow inquiring experts on identity in order to evaluate these concepts and correct the theoretical perspectives.
