On trust, knowledge, sharing and innovation

Organisations continuously innovate, create, and are competitive if they improve their performance through continuous intellectual capital development, a key resource for value creation and organisational performance driver. Apart from sustaining competitive advantage, intellectual capital is increasingly important due to its ability to increase shareholder value, especially in public organisations. Employee learning, talent development, and knowledge creation allow the organisation to generate innovative ideas due to the quickness of knowledge obsolescence. The organisation's dynamic capabilities create and re-ignite organisational competencies for business sustainability being co-ordinated by well-structured organisational strategic routines ensuring continuous value creation streams into the business. This chapter focuses on the relationship between notions of knowledge sharing and trust in organisations. Lack of trust can impact negatively organisational knowledge sharing, dependent on trust, openness, and communication. The research sample included graduates and postgraduate students from two universities in Portugal. The findings revealed different perceptions according to the age group.

Vidas de literacia — (re)configurações da relação com o escrito entre adultos em processos de RVCC

No âmbito de um projeto mais vasto centrado nas biografias de literacia de adultos envolvidos em processos de Reconhecimento, Validação e Certificação de Competências, neste texto caracterizamos percursos de vida, no que diz respeito aos usos de textos, de 5 adultos desempregados do distrito de Braga que, em 2012, concluíram o 3º Ciclo do Ensino Básico. A partir da combinação de dados recolhidos por questionário e entrevista, que visaram aceder a práticas, conceções e valores da leitura e da escrita, procuramos compreender de que modo a participação no processo de RVCC atuou na transformação das linguagens vernáculas, por um lado, e, por outro lado, na aquisição de novas linguagens sociais, ou seja, de novos modos de falar e escrever em situação. Assumindo-se que as práticas de linguagem são indissociáveis dos contextos socioculturais em que as pessoas se movimentam, em foco estarão as características das práticas de leitura e escrita dos 5 adultos, especificamente quanto a o quê, para quê e em que circunstâncias leem e escrevem ao longo das suas vidas. Nestes percursos, reconstituem-se as mudanças geradas pela frequência do RVCC, e que moldam as suas identidades de literacia. Entre as principais conclusões, destaca-se nestes sujeitos, tidos como “iletrados”, a presença e variedade de atividades de interação com textos, por meio de textos e sobre textos. Neste sentido, a frequência e finalidade do RVCC contribuem para acrescentar aos kits de identidade destes cinco adultos os traços e os valores que as comunidades letradas atribuem, sobretudo, à leitura.

Immediate and long term evolution of valve replacement in children less than 12 years old

OBJECTIVE: The aim of this work was the follow-up and evaluation of valve replacement in children under 12 years of age. METHODS: Forty-four children less than 12 years old were underwent valve replacement at INCOR-HCFMUSP between January 1986 and December 1992. Forty (91%) were rheumatic, 39 (88.7%) were in functional classes II or IV, 19 (43.2%) were operated upon on an emergency basis, and 6 (13.6%) had atrial fibrillation. Biological prostheses (BP) were employed in 26 patients (59.1%), and mechanical prostheses (MP) in 18 (40.9%). Mitral valves were replaced in 30 (68.7%), aortic valves in 8 (18.2%), a tricuspid valve in 1 (2.3%), and double (aortic and mitral) valves in 5 (11.4) of the patients. RESULTS: Hospital mortality was of 4.5% (2 cases). The mean follow-up period was 5.8 years. Re-operations occurred in 63.3% of the patients with BP and in 12.5% of those with MP (p=0.002). Infectious endocarditis was present in 26.3% of the BP, but in none of the cases of MP (p=0.049). Thrombosis occurred in 2 (12.5%) and hemorrhage in one (6.5%) of the patients with a MP. Delayed mortality occurred in 5 (11.9%) of the patients over a mean period of 2.6 years; four had had BP and one had a MP (NS). Actuarial survival and re-operation-free curves after 10 years were respectively, 82.5±7.7 (SD)% and 20.6±15.9%. CONCLUSION: Patients with MP required fewer re-operation, had less infectious endocarditis and lower late mortality rates compared with patients with bioprostheses. The former, therefore, appear to be the best valve replacement for pediatric patients.

Interpersonal and attitudinal factors in women's work role: Cross-cultural comparison

The last four decades have seen a dramatic increase in the number of women entering employment. This is particularly true in Europe and although more European women are working outside the home, the patterns of female employment have changed very little. An analysis of these patterns is presented. It was found that women continue to dominate specific fields, particularly teaching and service providing. An investigation of the interpersonal behavior differences among 117 American women from the southeastern United States in three work roles--homemakers, women in traditional occupations, and in nontraditional occupations--was conducted and the sex-role orientation, attitudes toward success, and demographic indicators were examined in order to consider the interplay of these variables with female occupational role and interpersonal behavior. A second focus of the study is on the cross-cultural comparison of the psychological and work variables in women of two different cultures: America and Portugal. Thirty-one Portuguese women were a preliminary comparison sample. The American results showed significant differences between groups in self-perceived interpersonal behaviors and the findings contradicted current stereotypes. The cross-cultural data, although preliminary, indicates differences between the countries in social desirability, aggressive and assertive behaviors, and in sex-role attitudes, which seem to reflect the different stages of economic development.
