Success or failure in knowledge management systems: a universal issue

This paper takes a sociotechnical viewpoint of knowledge management system (KMS) implementation in organizations considering issues such as stakeholder disenfranchisement, lack of communication, and the low involvement of key personnel in system design asking whether KMS designers could learn from applying sociotechnical principles to their systems. The paper discusses design elements drawn from the sociotechnical principles essential for the success of IS and makes recommendations to increase the success of KMS in organizations. It also provides guidelines derived from Clegg’s Principles (2000) for KMS designers to enhance their designs. Our data comes from the application of a plurality of analysis methods on a large comprehensive global survey conducted from 2007 to 2011 of 1034 participants from 76 countries. The survey covers a variety of organizations of all types and sizes from a comprehensive selection of economic sectors and industries. Our results showed that users were not satisfied with the information and knowledge systems that they were being offered. In addition to multiple technology and usability issues, there were human and organisational barriers that prevented the systems from being used to their full potential. We recommend that users of KMS are integrated into the design team so that these usability and other barriers can be addressed during the feasibility stage as well as the actual design and implementation phases.

Study on the changes of soil chemical characteristics as result of prescribed fire

Every year, particularly during the summer period, the Portuguese forests are devastated by forest fire that destroys their ecosystems. So in order to prevent these forest fires, public and private authorities frequently use methods for the reduction of combustible mass as the prescribed fire and the mechanical vegetation pruning. All of these methods of prevention of forest fires alter the vegetation layer and/or soil [1-2]. This work aimed the study of the variation of some chemical characteristics of soil that suffered prescribed fire. The studied an area was located in the Serra of Cabreira (Figure 1) with 54.6 ha. Twenty sampling points were randomly selected and samples were collected with a shovel before, just after the prescribed fire, and 125 and 196 days after that event. The parameters that were studied were: pH, soil moisture, organic matter and iron, magnesium and potassium total concentration. All the analysis followed International Standard Methodologies. This work allowed to conclude that: a) after the prescribed fire; i) the pH remained practically equal to the the initial value; ii) occurred a slight increase of the average of the organic matter contents and iron total contents; b) at the end of the sampling period compared to the initial values; i) the pH didn´t change significantly; ii) the average of the contents of organic matter decreased; and iii) the average of the total contents of Fe, Mg and K increased.

Non-uniform printed antenna array for wireless communications in sports arenas

Wireless communications had a great development in the last years and nowadays they are present everywhere, public and private, being increasingly used for different applications. Their application in the business of sports events as a means to improve the experience of the fans at the games is becoming essential, such as sharing messages and multimedia material on social networks. In the stadiums, given the high density of people, the wireless networks require very large data capacity. Hence radio coverage employing many small sized sectors is unavoidable. In this paper, an antenna is designed to operate in the Wi-Fi 5GHz frequency band, with a directive radiation pattern suitable to this kind of applications. Furthermore, despite the large bandwidth and low losses, this antenna has been developed using low cost, off-the-shelf materials without sacrificing quality or performance, essential to mass production. © 2015 EurAAP.

Radioactivity studies in Porto urban area: gamma radiation of Paranhos sector

A set of radiation measurements were carried out in several public and private institutions. These were selected with basis on the people affluence and passage to these sites. These measurements were registration formed either indoor, outdoor or underground and were compiled in three Case Studies. Radiation doses measurements were also made, surface and underground locations, and compiled in other two Case Studies. There were sampled, at the same time, humidity, temperature, atmospheric pressure and relevant construction materials at sampling locations. They were collected and registration formed to analyse if there is any relation or contribution for the measured value in each specific place. Geostatistical models were used to elaborate maps of the results both for radiation values and for doses. Preliminary relations were established among the measured parameters.

A aceitação de alunos com necessidades educativas especiais passados 6 anos da implementação do Decreto-Lei nº3/2008:opinião de educadores de infância e de professores do 1ºciclo

Objetivo: A compreensão da Educação Especial no paradigma da inclusão envolve vontade política e social e mobiliza necessariamente os profissionais de educação, sendo fundamental conhecer a sua opinião. Em Portugal, o Decreto-Lei n.º 3/2008 trouxe mudanças significativas no papel dos docentes do ensino regular, pelo que este estudo tem como objetivo, passados 6 anos da implementação, descrever a opinião de educadores e professores do 1º ciclo acerca da inclusão de alunos com Necessidades Educativas Especiais e conhecer os fatores que justificam as suas opiniões. Método: Foram inquiridos 244 docentes, 122 educadores de infância e 122 professores do 1º ciclo de escolas públicas e privadas, da Área Metropolitana do Porto, os instrumentos usados foram uma folha de caracterização individual e um questionário de vinhetas com descrições do funcionamento de crianças, onde os respondentes se posicionavam, para cada uma, quanto à sua aceitação nas salas. Resultados /Discussão: Os resultados apontam que as vinhetas que descreviam funcionamentos de crianças compatíveis com Perturbação de Espetro de Autismo e Paralisia Cerebral, foram as menos, sendo as justificações a falta de formação e a impossibilidade de despender o tempo necessário devido à exigência de bons resultados académicos. Aferimos que a formação em Educação Especial apenas estava associada à aceitação de alunos com Paralisia Cerebral. Aferimos que a função do docente-educador vs professor do 1ºciclo- apenas é influenciadora de aceitação no caso de alunos com Perturbação de Espetro de Autismo, Paralisia Cerebral e Atraso Global de Desenvolvimento/Dificuldades de Aprendizagem. O facto de se tratar de uma escola pública ou privada influencia a aceitação dos alunos, com os docentes do ensino privado a evidenciarem maior aceitação dos alunos do que os do ensino público.

Guia de Implementação BIM em organizações e projetos

A adoção da metodologia BIM (Building Information Modeling) é vista como um processo transformador que engloba as empresas e os seus projetos e, em última instância, toda a Indústria da Construção Civil. Devido ao facto de que o BIM é um complexo sistema cuja implementação tem impactos sociais, técnicos e metodológicos, este tema há já alguns anos que tem sido alvo de pesquisas com o objetivo primordial de difundir as práticas associadas ao BIM nas empresas, nos seus projetos, e na indústria. Um pouco por todo mundo, várias iniciativas de entidades públicas e privadas, governamentais e não-governamentais, têm produzido guias, normas, manuais e outros documentos que funcionam como um motor propulsor da implementação BIM. O presente trabalho contém a proposta de um Guia de Implementação da Metodologia BIM, desenvolvido no contexto do um estágio curricular levado a cabo na empresa Building Information Modeling & Management Solutions (BIMMS) e que resultou do estudo e adaptação de alguns dos mais conceituados guias, normas e manuais BIM existentes e em vigor noutros países. Este documento de caráter técnico e prático foi concebido para servir o propósito de auxiliar gabinetes de Engenharia, Arquitetura, e empresas de Construção na integração do BIM na sua atividade e foi elaborado com o intuito de poder ser divulgado e utilizado como referência a nível nacional.

Success in higher education

This paper analyses the determinants of success of undergraduate Nova SBE students from 2008 to 2011. We account for the question of selection that is likely to occur when we just observe the success of those students who were admitted and enrolled at school. The main result of our empirical analysis is that the high school score appears to be a stronger predictor of the students´ success than the national Math’s exam score. In addition, the evidence also suggests that male students tend to have a better performance in Economics than female students and displaced management students have more difficulties in terms of their scores. Finally, it does not seem to exist a strong visible difference on the final GPA between students from public and private schools.

A possibilidade de utilização das publicações nas redes sociais como prova nos procedimentos disciplinares e despedimento dos trabalhadores

In these days, Internet and social media represent a big advance in communication. Using the internet brings people a lot of benefits and facilities, but with them comes risks and problems that are turning the line between public and private life smaller. The frequent use of internet and the unbridled use of it we see nowadays on its utilization brings problems related to people privacy, and the dividing line between private and public life is becoming more blurred and admitting the employer intromission on employee’s private life. So, it assumes the largest importance understand in which way this employee’s on exposure on social media brings problems and risks to employment relationship and establish some criteria in order to decide what needs legal protection. But should we affirm that protection when the employee’s publications on social media brings problems to the employer or the company? We think, in these cases, and considering some facts, employee’s private life should cede before the employer’s rights.

O âmbito de aplicação material da legislação de proteção de dados pessoais e o tratamento de imagem por pessoa singular

Images have gained a never before seen importance. Technological changes have given the Information Society extraordinary means to capture, treat and transmit images, wheter your own or those of others, with or without a commercial purpose, with no boundaries of time or country, without “any kind of eraser”. From the several different ways natural persons may engage in image processing with no commercial purpose, the cases of sharing pictures through social networks and video surveillance assume particular relevance. Consequently there are growing legitimate concerns with the protection of one's image, since its processing may sometimes generate situations of privacy invasion or put at risk other fundamental rights. With this in mind, the present thesis arises from the question: what are the existent legal instruments in Portuguese Law that enable citizens to protect themselves from the abusive usage of their own pictures, whether because that image have been captured by a smartphone or some video surveillance camera, whether because it was massively shared through a blog or some social network? There is no question the one's right to not having his or her image used in an abusive way is protected by the Portuguese constitution, through the article 26th CRP, as well as personally right, under the article 79th of the Civil Code, and finally through criminal law, articles 192nd and 193rd of the Criminal Code. The question arises in the personal data protection context, considering that one's picture, given certain conditions, is personal data. Both the Directive 95/46/CE dated from 1995 as well as the LPD from 1998 are applicable to the processing of personal data, but both exclude situations of natural persons doing so in the pursuit of activities strictly personal or family-related. These laws demand complex procedures to natural persons, such as the preemptive formal authorisation request to the Data Protection National Commission. Failing to do so a natural person may result in the application of fines as high as €2.500,00 or even criminal charges. Consequently, the present thesis aims to study if the image processing with no commercial purposes by a natural person in the context of social networks or through video surveillance belongs to the domain of the existent personal data protection law. To that effect, it was made general considerations regarding the concept of video surveillance, what is its regimen, in a way that it may be distinguishable from Steve Mann's definition of sousveillance, and what are the associated obligations in order to better understand the concept's essence. The application of the existent laws on personal data protection to images processing by natural persons has been analysed taking into account the Directive 95/46/CE, the LPD and the General Regulation. From this analysis it is concluded that the regimen from 1995 to 1998 is out of touch with reality creating an absence of legal shielding in the personal data protection law, a flaw that doesn't exist because compensated by the right to image as a right to personality, that anyway reveals the inability of the Portuguese legislator to face the new technological challenges. It is urgent to legislate. A contrary interpretation will evidence the unconstitutionality of several rules on the LPD due to the obligations natural persons are bound to that violate the right to the freedom of speech and information, which would be inadequate and disproportionate. Considering the recently approved General Regulation and in the case it becomes the final version, the use for natural person of video surveillance of private spaces, Google Glass (in public and private places) and other similar gadgets used to recreational purposes, as well as social networks are subject to its regulation only if the images are shared without limits or existing commercial purposes. Video surveillance of public spaces in all situations is subject to General Regulation provisions.

International Partnering strategy for e-learning provider in emerging economies: Evidence from East Africa learning institutions

International partnership has received growing interest in the literature during the past decades due to globalization, increased technological approaches and rapid changes in competitive environments. The study specifically determines the support provided by international partners on promotion of e-learning in East Africa, assess the motives of partner selection criteria, the determinants of selecting partners, partner models and partner competence of e-learning provider. The study also evaluates obstacles of e-learning partnering strategy in East Africa learning institutions. The research adopts a descriptive survey design. Target population involved East Africa learning institutions with a list of potential institutions generated from the Ministry of Higher Education database. Through a targeted reduction of the initial database, consisting of all learning institutions, both public and private, the study created a target sample base of 200 learning institutions. Structured questionnaires scheduled were used to collect primary data. Study findings showed the approach way East African communities in selecting their e-learning partners depend on international reputation of partners, partner with ability to negotiate with foreign governments, partner with international and local experiences, nationality of foreign partner and partners with local market knowledge.
