- Abordagem contingencial à relação entre inovação, autonomia, desempenho e resultados organizacionaisPublication . Fontes, Carla; Leite, Joaquim; Fernandes, Paula OdeteO principal objetivo deste estudo é validar as relações de interdependência entre estratégia de inovação nos serviços, autonomia estrutural, sistemas de avaliação de desempenho e resultados organizacionais de eficácia e eficiência, tendo como suporte a teoria da contingência. A pesquisa foi baseada em dados recolhidos através de inquéritos por questionário enviados aos diretores de escolas do ensino secundário do setor público de Portugal continental. Recorreu-se ao uso de estatísticas descritivas, ao coeficiente de correlação de Spearman e Análise de Equações Estruturais, no tratamento dos dados. A evidência demonstrou que existem algumas relações entre as variáveis estudadas, reforçando proposições da teoria da contingência organizacional.

- Academic entrepreneurship framework: the best practices of Bragança Polytechnic InstitutePublication . Pires, José Adriano; Fernandes, Paula Odete; Sampaio, Jorge Humberto; Lopes, JoanaAcademics in the fields of entrepreneurship and innovation studies have long been interested in the entrepreneurial behaviour of Higher Education researchers and Higher Education Institutions entrepreneurial activities more generally (Chrisman et al., 1995; Stuart & Ding, 2006; Rothaermel et al., 2007). Some academics are in agreement that the contribution of academic researchers in business activities solves some imperfections in the transmission of knowledge, and motivates researchers to undertake projects with greater economic and social relevance (Gittelman & Kogut, 2003; Etzkowitz, 2004).
- Acceptance of wearables: a comparative study between Portugal and BrazilPublication . Niada, Aurea; Sá, Matheus Beltrame de; Fernandes, Paula Odete; Lopes, Isabel MariaThis research work focuses on understanding receptivity to devices wearable in Portugal and Brazil, examining factors such as demographic profiles, experiences with technology and personal impressions. To this end, responses were collected from university students and other internet users through a ques tionnaire using the Likert scale. Data analysis revealed a predominance of par ticipants located in Portugal, with a more pronounced acceptance trend among younger audience, with a higher level of education and a greater technological proficiency between men and more educated people. The ratio between wearable users and non-users proved to be equitable, highlighting a more expressive accep tance on the part of individuals among 35–59 years old, women and those with a positive perception towards technology. Among the devices analyzed, the smart watch stood out, being followed by the fitness bracelet and the ring intelligent. A variation in social influence was noted depending on the type of device, this being more expressive in the case of smartwatches. Unexpectedly, social influence does not proved as decisive in the acceptance of wearables as initially assumed. The results show an inclination towards the adoption of these devices, while at the same time signaling for challenges linked to the perceived value and, therefore, the cost of products, indicating a field promising for future investigations and innovations.
- Acoustic analysis of chronic laryngitis - statistical analysis of sustained speech parametersPublication . Teixeira, João Paulo; Fernandes, Joana Filipa Teixeira; Teixeira, Felipe; Fernandes, Paula OdeteThis paper describes the statistical analysis of a set of features extracted from the speech of sustained vowels of patients with chronic laryngitis and control subjects. The idea is to identify which features can be useful in a classification intelligent system to discriminate between pathologic and healthy voices. The set of features analysed consist in the Jitter, Shimmer Harmonic to Noise Ratio (HNR), Noise to Harmonic Ratio (NHR) and Autocorrelation extracted from the sound of a sustained vowels /a/, /i/ and /u/ in a low, neutral and high tones. The results showed that besides the absolute Jitter, no statistical significance exist between male and female voices, considering the classification between pathologic or healthy. Any of the analysed parameters is likely to be a statistical difference between control and Chronic Laryngitis groups. This is an important information that these features can be used in an intelligent system to classify healthy from Chronic Laryngitis voices.
- Acoustic analysis of vocal dysphoniaPublication . Teixeira, João Paulo; Fernandes, Paula OdeteVoice acoustic analysis is becoming more and more usefúl in diagnosis of voice disorders or laryngological pathologies. The facility to record a voice sigiial is an advantage over other invasive techniques. This paper presents the statistical analyzes ofa set of voice parameters like jitter, shimmer and HNR over a 4 groups of subjects vvith dysphonia, fünctional dysphonia, hyperfünctional dysphonia, and psychogenic dysphonia and a control group. No statistical signifícance differences over pathologic groups were found but clear tendencies can be seen between pathologic and control group. The tendencies indicates this parameters as a good features to be used in an intelligent diagnosis system, moreover the jitter and shimmer parameters measured over different tones and vowels.

- Agency theory approach of the relationship between performance, compensation and value creation in the companies listed on Euronext LisbonPublication . Serapicos, Armando; Leite, Joaquim; Fernandes, Paula OdeteThe aim of the present study was to understand, in Portugal, relationships between the Chief Executive Officer (CEO) and the organizational performance, on the one hand, and relationships between the shareholder value creation and the CEO total compensation, on the other hand. This research is divided into two parts. The first part was examined whether organizational performance based on accounting measures influences organizational performance based on market measures and whether organizational performance based on accounting measures and market measures influences the CEO total compensation. The second part of the study analyses whether organizational performance, based on accounting measures and market measures, and the CEO total compensation influence the shareholder value creation. This research was based on agency theory assumptions in order to build the analysis model. The sample was composed of companies listed on Euronext Lisbon. The data analysis was performed using the structural equation modelling method. The results showed that organizational performance based on accounting measures influences organizational performance based on market measures, the CEO total compensation and the shareholder value creation.
- Agency theory approach of the relationship between performance, compensation and value creation in the companies listed on Euronext LisbonPublication . Serapicos, Armando; Leite, Joaquim; Fernandes, Paula OdeteThe aim of the present study was to understand, in Portugal, relationships between the behaviour of the Chief Executive Officer (CEO) and the organizational performance, on the one hand, and relationships between the shareholder value creation and the CEO total compensation, on the other hand. This research is divided into two parts. The first part was examined whether organizational performance based on accounting measures influences organizational performance supported by market measures and whether organizational performance based on accounting measures and market measures influences the CEO total compensation. The second part of the study analyses whether organizational performance, based on accounting measures and market measures, and the CEO total compensation influence the shareholder value creation. This research was based in agency theory assumptions in order to build the analysis model. The sample was composed by companies listed on Euronext Lisbon.

- An empirical analysis of the dimensions of corporate social responsibility in PortugalPublication . Afonso, Sandra Cristina; Fernandes, Paula Odete; Monte, Ana PaulaThis paper investigates factors that can explain the motivations of Portuguese companies to a social performance. The study was based on a sample of nineteen large Portuguese companies, listed on the PSI 20 index, for a period of five year, since 2005 to 2009. A Factorial Analysis was applied to identify the dimensions of Portuguese Corporate Social Responsibility using variables reference on the Green Book of European Community Commission (ECC, 2001). The results produced two dimensions that may explain Portuguese corporate motivation social performance: (1) Standards and Legal Requirements and (2) Ethic and social conduct. Further research may be done to find correlations with these dimensions and financial and economic corporate performance.
