Diffusion and efficiency of ISO 9001 in Portugal: a qualitative and quantitative study from a holistic theoretical perspective

Purpose – the aim of this paper is to analyse the diffusion and efficiency of ISO 9001 on different sectors of activity Design/methodology/approach – for that purpose, a holistic an integrative theoretical approach was based on the scope of the Contingency theory, the Institutional theory and the Resources-Based View (RBV). This theorethical perspective was used in a broad empirical study, using a qualitative and quantitative methodology, concerning Portuguese companies from different sectors of activity. Findings – according to the findings from both perspectives, a ranked combination of the named theoretical frame was constructed. Research limitations/implications – as to the analysis of the efficiency of ISO 9000, one of the limitations of this study lays in the consideration of just two sectors of activity, and another relates to its domestic geographical placement. Practical implications – this study used the ISO 9001 structure for the interviews and this has revealed very useful for the organizations to grasp the matters inquired. Originality/value – a relevant contribution to the state of art is achieved through the considered theoretical scope of analysis

Study of the rheology of self-compacting concrete with fine recycled concrete aggregates

This work studies the effect of incorporating fine recycled aggregates on the rheology of self-compacting concrete over time (at 15,45 and 90 min). The fine fraction of the natural aggregates was replaced at 0%, 20%, 50% and 100% with recycled sand. The fresh-state properties were studied by empirical tests (slump-flow, J-Ring, L-Box) and fundamental ones in an ICAR rheometer. The mixes with 50% and 100% recycled sand lost their SCC characteristics at 90 min. Contrarily the mix with 20% replacement maintained suitable passing and filling ability. The causes of this trend were an initial increase of plastic viscosity and afterwards an increase of yield stress. The compressive strength of the 50% and 100% replacement mixes decreased significantly and that of the 20% replacement mix less than 10%. (C) 2015 Elsevier Ltd. All rights reserved.

The influence of pre-departure training on expatriate adjustment: an empirical investigation with portuguese international assignees

This chapter examines the cross-cultural influence of training on the adjustment of international assignees. We focus on the pre-departure training (PDT) before an international assignment. It is an important topic because in the globalized world of today more and more expatriations are needed. The absence of PDT may generate the failure of the expatriation experience. Companies may neglect PDT due to cost reduction practices and ignorance of the need for it. Data were collected through semi-structured interviews to 42 Portuguese international assignees and 18 organizational representatives from nine Portuguese companies. The results suggest that companies should develop PDT programs, particularly when the cultural distance to the host country is bigger and when there is no previous experience of expatriation to that country in the company. The study is original because it details in depth the methods of PDT, its problems, and consequences. Some limitations linked to the research design and detailed in the conclusion should be overcome in future studies.

Protecção radiológica do doente em tomografia computorizada

RESUMO - A preocupação com os conhecimentos, atitudes, crenças e práticas, no que concerne à utilização de radiações ionizantes para fins de diagnóstico, e a sensibilização de todos os agentes envolvidos, médicos, técnicos, físicos, utentes e responsáveis pela Saúde Publica, relativamente aos níveis de radiação emitida nos exames de Tomografia Computorizada (TC), assume particular importância no domínio da Saúde Pública, na medida em que é necessário influenciar o desenvolvimento de práticas que promovam, auditem e garantam a prestação do controlo da qualidade radiológica e dosimétrica nos serviços de Radiologia a nível Nacional. Para tal, e no âmbito da publicação de estudos já realizados ao nível da União Europeia, ―Orientações Europeias dos Critérios de Qualidade para a Tomografia Computorizada (1999) ‖, é proposto estabelecer orientações na realização de estudos que permitam, numa primeira fase, estabelecer a comparação com os resultados obtidos pelos mecanismos de Controlo da Qualidade (CQ), analisar e proceder aos ajustes (se necessário) e, numa segunda fase, implementar uma moldura sistemática de avaliação periódica dos níveis de dose de radiação por exame TC e que permita a monitorização dos dados. Nesse sentido, propõe-se a realização de um Estudo Nacional que envolva a rede hospitalar pública, privada e universitária, partindo da metodologia utilizada em estudos prévios noutros países da Europa, como seja, selecção do equipamento de TC existente na Instituição Hospitalar, onde serão reunidas informações através do preenchimento de questionários relativos ao equipamento a utilizar. Serão recolhidos dados relativos ao utente, ao equipamento e parâmetros de aquisição de imagem, que permitam identificar os níveis de referência de diagnóstico (NRD) em TC, na realidade Portuguesa. Foi efectuado um estudo piloto numa instituição EPE e os valores obtidos não são significativos, nem podem assumir valor preditivo dado o reduzido tamanho da amostra. Apesar disso, sugerem a existência de parâmetros que podem ser alterados e com isso podem fazer variar a dose de radiação utilizada. ENSP/UNL Maria de Fátima Vaz de Carvalho 5 Espera-se obter com este estudo, como foi referido, a base do estabelecimento dos NRD em TC em Portugal. ----------------- ABSTRACT - The purpose of this study, in an empirical point of view, emerges from concern with the knowledge, attitudes, beliefs and practices regarding the use of ionizing radiation for diagnostic purposes and awareness of all actors involved, medical physical, technical, and responsible public health for the development of practices that promote, audited and ensure the provision of radiological quality control and dosing in radiology service at national level. In view of the complexity and characteristics involved in relation to ionizing radiation, all assume their part in protecting the physical integrity of each user and a global perspective, to ensure the safeguarding of public health, while global and globalizing factor. To this end, and in the context of the publication of studies already carried out at European Union level, "European guidelines for quality criteria for computed tomography", it is proposed to establish guidelines in conducting studies to initially establish the comparison with the results obtained by QC and make adjustments if necessary, and subsequently implement a systematic periodic assessment frame that allows monitoring of data. Accordingly, it is proposed to conduct a national study involving the public network, private and University hospitals, that extends from the methodology used in previous studies in other countries of Europe, as is, selection of equipment of existing CT in Hospital Institution, where information will be gathered by filling out questionnaires concerning the equipment to be used. Data will be collected for the wearer, equipment and parameters of image acquisition, identifying diagnostic reference levels (NRD) in CT in Portuguese fact. A pilot study was carried out in an institution EPE and the values obtained are not significant, nor can they take predictive value given the small sample size. Despite this, suggest the existence of parameters that can be changed and this can vary the dose of radiation used It is hoped to get with this study, as mentioned, the basis of the establishment of NRD in CT in Portugal.

Two divergent ways to manage HR and to get to the top: an exploratory study in micro firms

Aim of the paper: The purpose of this paper is to examine human resources management practices (HRM practices) in small firms and to improve the understanding of the relationship between this kind of practices and business growth. This exploratory study is based on the resource-based view of the firm and empirical work carried out in two small firms by relating HRM practices with the firms’ results. Contribution to the literature: This is an in-depth study of HRM practices and its impact on performance growth in micro firms, isolating and controlling for most of the contextual and internal variables considered in the literature that relate HRM to growth. Firm growth analysis was broadened by the use of several dependent variables: employment growth and operational and financial performance growth. Some hypotheses for further research in identifying HRM practices in small business and its relation with firm growth are suggested. Methodology: Case study methodology was used to study two firms. The techniques used to collect data were semi-structured interviews to the owner and all the employees, unstructured observation at the firms’ facilities (during two days), entrepreneur profile definition (survey answer) and document data collection (on demographic characterization and performance results). Data was analyzed through content analysis methodology, and categories derived from the interviews’ protocols and literature. Results and implications: Results revealed that despite the firms’ organizational characteristics similarities, they differ significantly in owners’ motivation to grow, HRM practices and organizational performance and growth. Future studies should pay special attention to owner willingness to grow, to firms’ years of experience in business, to staff’s years of experience in their field of work and turnover. HRM practices in micro/small firms should be better defined and characterized. The external image of management posture relating to longitudinal financial results and growth should also be explored.

The relationship between knowledge acquisition on international assignments and career development: an exploratory study with portuguese repatriates

This paper explores the relationship between the expatriates’ knowledge acquisition (KA) and their career development after an international assignment (IA). The purpose of this paper is to examine the role of expatriates in KA and transfer within International Portuguese multinational corporations. Furthermore, with this empirical study we try to analyse how the knowledge that is acquired and transferred translates into a basis for career development after the IA. This phenomenon has a special relevance in the Portuguese context, because this country is known a growing process of globalization in recent years. Furthermore, (a) there are no empirical studies concerning knowledge transfer and career development of repatriates from Portuguese companies; (b) little is known about the repatriates’ contributions to their home company after IA. This paper is one of the first to focus specifically on the repatriates’ role in KA and transfer from the host company to their Portuguese home company. A qualitative research methodology is used, specifically through an exploratory case study approach, which examines how knowledge management (KM) acquisition or transferring during IA are important for the repatriates’ career development in the Portuguese home company. Data were collected through semi-structured interviews to 42 Portuguese international assignees and 18 organizational representatives from nine Portuguese companies. Preliminary results show that KA and transfer made by Portuguese expatriates contributes directly to their career development. Moreover, evidence reveals that not all repatriates were promoted after their IA; rather some repatriates were even demoted after their IA. Furthermore, the results obtained suggest that the type of knowledge which acquired or transferred plays a central role in the career development after repatriation. According to these results, the paper discusses the major theoretical and practical implications. Suggestions for future research are also presented.
