A New Governance Model for Independent Regulatory Agencies  [PDF]
Rui Nunes, Sofia B. Nunes, Guilhermina Rego
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.51002
Abstract: In a regulatory state the purpose of intervention by any Independent Regulatory Agency (IRA) is not only regulation in the strict sense but also the supervision of the activity of institutions providing a specific service, particularly the utilities. However, given the evolution of most market economies, namely in transition countries, it is necessary to design new governance arrangements that enable an effective, transparent and truly independent intervention of IRAs. The objectives of this study are a) to analyse of the institutional-design chosen for some independent regulatory agencies and its regulatory framework, namely in northern economies, and b) to suggest the need to strengthen governance arrangements to effectively guarantee regulatory independence, transparency and accountability, therefore promoting a true sunshine regulation in southern economies. The authors conclude that strengthening accountability arrangements is the most important mechanism to avoid regulators capture from the government and regulated organisations. It is also concluded that the way regulators have chosen can also influence the way IRA conducts its activity. Therefore, it is suggested that board accountability can be enhanced by the generalization of the principle of the public contest of regulators.
Hospital Foundation: A SWOT Analysis  [PDF]
Guilhermina Rego, Rui Nunes
iBusiness (IB) , 2010, DOI: 10.4236/ib.2010.23026
Abstract: The reform of Portuguese public hospitals can be described as an evolution by “waves”. A first “wave” took place in 2002, when 34 public hospitals were transformed into State-owned hospital enterprises (SA hospitals). Subsequently, in January 2006, the SA hospitals and some of the traditional public administration hospitals (SPA hospitals) were changed into public business enterprises (EPE hospitals). That was the second “wave” that is the stage we are at pre- sent. A possible third “wave” can be related with the possibility of conversion of the EPE hospitals into State Hospital Foundations (SHF). This paper tries to identify if this new management model has more capacity to influence positively values such as efficiency, equity, quality, governance, empowerment and accountability than the previous existing model. For this purpose it was developed a strategic analysis including an evaluation of some internationals experi- ences, and also a SWOT analysis was performed. The authors conclude that the introduction of SHF model is a very plausible alternative. The model of governance can make the difference and promote its implementation. Due to the participative management model, the process of accountability can be more “visible” and the regulatory process of this management model seems to be more effective.
Interactive Digital Games for Geography Teaching and Understanding Geographical Space  [PDF]
Christian Nunes da Silva
Creative Education (CE) , 2015, DOI: 10.4236/ce.2015.67070
Abstract: This article aims to analyze and discuss the use of digital interactive games, such as learning tools to be used by educators in the classroom, as a resource for geography teaching-learning process in the early grades. This discussion arose from the analysis by geography course graduation students of the Federal University of Pará (UFPA), in the years 2013 and 2014, at which this tool has gained recognition of its potential by students. In this sense, the objective is a brief discussion, based on the analysis of some selected examples on how these digital games can become fundamental importance of resources for teaching Geography and how these should be used and applied in the classroom by educators in a critical way, which will allow students to have adequate learning about the geographic space.
Application of a Configurable Model for Risk Assessment in the Work Sites  [PDF]
Fernando Oliveira Nunes
Open Journal of Safety Science and Technology (OJSST) , 2016, DOI: 10.4236/ojsst.2016.64009
Abstract: This paper presents a configurable model for occupational risk analysis, supported in decision matrix risk assessment with variable indexes dimensions and weightings. The formulation proposed seeks to overcome typical limitations such as range compression effect, mistakenly over classification of smaller risks and subjective input information. Also it allows its customization for each type of risk as a function of input information available in order to minimize subjectivity, while normalizing output for the calculated risk levels with a percent scale. This approach facilitates the implementation of models built to go along with the life of installations with periodically updates to fulfill accumulated data. To avoid discontinuation of procedures and practices implemented in the organizations, the model also enables the easy incorporation of risk assessment and control procedures based on risk classification matrixes, already in use regardless of their size and sector of activity.
Mudan a e varia o na terminologia a ucareira actual do Brasil
Naidea Nunes Nunes
Linguística : Revista de Estudos Linguísticos da Universidade do Porto , 2008,
Abstract: This comparative study intends to understand the change and variation in the actual terminology of sugar cane in different Brazilian States (Paraíba, Pernambuco, Baía, Minas Gerais, Santa Catarina and Rio Grande do Sul). This study, besides the terminological variation, allows us to observe some historic, geographic and social variation. We can find old and new terms, respectively in conservative and innovative regions, explained by historic and geographic factors. At the same time, there is the use of popular words and technical terms (social variation). But the main variation is the terminological one: synonymous and polysemic forms that show us a change in course, like it happens in common language
Estimation of pulmonary capillary pressure: different methods for different pathophysiological processes?
Silvia Nunes
Critical Care , 2004, DOI: 10.1186/cc3060
Abstract: In healthy individuals pulmonary vascular resistance is low and is mostly located within the pulmonary arterial bed. In the absence of significant venous resistance, pulmonary capillary pressure (PCP) is very close to the pulmonary arterial occlusion pressure. Under these circumstances, pulmonary arterial occlusion pressure may be used as a surrogate for the pressure determining filtration from the capillaries to the interstitium (PCP). However, this is no longer the case when pulmonary venous resistance is increased, as may occur in pulmonary hypertension of various aetiologies, acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). In these patients PCP must be estimated by analyzing the pulmonary arterial pressure decay after pulmonary artery occlusion. Souza and coworkers [1] used this technique to estimate PCP by different methods in patients with idiopathic pulmonary arterial hypertension and with ARDS. These authors addressed the fundamental issue of whether the methods used to calculate PCP are adequate in different disease processes.In idiopathic pulmonary arterial hypertension, the massive increase in pulmonary arterial resistance accounts for most of the pulmonary resistance, even though some degree of venous resistance is also present [2]. In these patients, the use of a biexponential approach for the analysis of the pulmonary arterial pressure decay after occlusion appears to be more suitable than a monoexponential approach. A biexponential fit provides an estimation of both the fast and slow components of the pulmonary pressure drop, and therefore avoids assumptions regarding the time needed for emptying of the arterial compartment, which is markedly prolonged in this pathophysiological situation [3]. A monoexponential fit starting from 200 ms after occlusion may still include part of the pressure trace resulting from emptying of the pulmonary arterial compartment, as was suggested by the findings of Souza and coworkers [1]. As discuss
Tuberculosis incidence in Portugal: spatiotemporal clustering
Carla Nunes
International Journal of Health Geographics , 2007, DOI: 10.1186/1476-072x-6-30
Abstract: Continental Portugal is organized in 18 districts with 278 sub-districts. For this case study, the number of new notified cases of TB, per sub-district and per year (2000–2004) was available. TB incidence presents clear spatial patterns: a semivariogram consistent with 40% of nugget effect and 60% of spatial contribution, following an exponential model with a range of 143 kilometres. Temporal semivariograms were not conclusive, as only 5 years of data were available. The spatial and temporal persistence of clusters were analyzed considering different models. Significant high incidence rate space-time clusters were identified in three areas of Portugal (between 2000 and 2004) and a purely temporal cluster was identified covering the whole country, during 2002.In terms of spatiotemporal clustering of tuberculosis disease, the proposed methodology allowed the identification of critical spatiotemporal areas. In Portugal there were 3 critical districts (Porto, Setúbal and Lisbon) with high rates of notified incidences between 2000 and 2004. In methodological terms, semivariogram parameters were successfully applied to define spatiotemporal scan window sizes and shapes (ellipsoidal cylinders), showing very good results and performances in the case study. After defining the clusters, these were authenticated through a validation method, based on geostatistical simulations.In 1993, the World Health Organization (WHO) declared tuberculosis (TB) to be a global emergency. Disease control is based on effective diagnosis, treatment and monitoring of TB cases, and must undergo a directly observed short course therapy [1]; this defines "DOTS strategy". Some authors sustain that tuberculosis can be controlled only if appropriate policies are followed and effective clinical and public health management is ensured [2]. New perspectives and ways of addressing TB treatment and control are needed.Disease mapping has a long history [3] and it is not surprising that this method of descrip
Conflitos de interesse: reflex?es ao regime do pós-emprego público
Economia Global e Gest?o , 2010,
Abstract: the legal regime applicable to the post-public employment situations states that the individuals who have held political positions, elected or appointed, cannot exercise, for a period of three years, from the end of their appointments or election, futures position that could possibly collide with the regime of incompatibilities, in particular, which may cause a conflict of interest . this article intends to make a synopsis and also make some reflections about the state of the art in such systems.
Anísio Teixeira entre nós: a defesa da educa??o como direito de todos
Nunes, Clarice;
Educa??o & Sociedade , 2000, DOI: 10.1590/S0101-73302000000400002
Abstract: the objective this article is to look back on anísio teixeira's life and work (1900-1971), on the 100th anniversary of his birth, including decisive moments in his biography, his motivations as an educator, different aspects of his appropriation of john dewey's work, and the usefulness of his conceptions for reflecting on contemporary brazilian education.
Elei??es de segunda ordem em Portugal: o caso das europeias de 2004
Análise Social , 2005,
Abstract: this article looks at the european elections of 2004 in the light of second-tier election theory. according to this model, higher abstention rates and better electoral performances from small and medium-sized parties are to be expected in this type of election. it is true that turnout in these elections continues to be low, but the performance of small parties in them does seem to be affected by the increasing trend towards two-party dominance in other elections. we have also confirmed that european elections operate as a sort of referendum on the government. halfway through a parliamentary term, at a time when the economy was not doing well, parties which supported the government were clearly made to suffer. moreover, the most significant factors affecting the 2004 european election results, apart from ideological positioning, were voters? assessment of the government?s performance and the economic situation. traditional social divisions are of little help in understanding the meaning of votes cast in european elections: turnout bears a strong relationship to age and to how interested the voter is in politics. the article does not support any conclusion that abstention in european elections is linked to negative attitudes vis-à-vis the european union or to the range of party platforms on offer.
