Ethics on scientific research is approached and often discussed in several areas of knowledge connected to health. In the Administration area there are very few studies which approach the topic of ethics on research. The present paper tried to fill in this gap in the production of knowledge about the topic, investigating how the ethical principles found in the literature and in the codes of conduct are noticed and taken into account in Administration research activities developed by acting researchers in Administration Post Graduation Programs. Theoretically speaking, the study was based mainly on the approaches by Creswell (2007) and Bell and Bryman (2007), which discuss the research ethical principles. Methodologically speaking it was all about an exploratory kind of study, with qualitative research approach. Upon data collection, personal interviews were made aiming at its depth and focus groups were formed. The first stage had interviews with four experienced researchers who took part on a teaching and researching event and on the second stage we used the focus group technique. The focus groups were done in four college institutions along with the post graduation programs in Administration in the states of Rio Grande do Norte, Paraíba and Pernambuco, in Brazil. The results suggest the existence of general principles and parameters for the scientific research recommended in the literature and on official resolution. However, in the Administration area, there are only a few recommendations of good practices when it comes to submitting articles for scientific publications but we found no guidance with ethical principles and parameters which cover all the activities in the scientific research and which specifically meet the research particularities in Administration. The main ethical dilemma pointed by the researchers refers to ethical questions which arise at the time of data collection and on disclosing the results. Most researchers do not know the guidelines and the ethical norms on ethics about research that we have in our country neither do they send in their projects to the research ethics committee. When dilemma arises, they decide the ethical question based on their values and common sense. These elements confirm the thesis that the researcher s procedure in the research activities in Administration is predominantly signed by personal values or by common sense and less by ethical principles, whether by not knowing the normative instruments related to ethics or by disagreeing with any disciplining rules on ethical behavior in the research

O presente trabalho visa conhecer o nível de notoriedade dos produtos tradicionais de origem animal (DOP e IGP) do Alentejo no mercado consumidor. Este objectivo foi alcançado através da realização de revisão bibliográfica com recurso às fontes secundárias disponíveis e de fontes primárias, nomeadamente de um questionário de avaliação da notoriedade dos produtos tradicionais (DOP e IGP) de origem animal do Alentejo expressamente desenvolvido para o efeito. A informação obtida permitiu caracterizar a oferta dos produtos tradicionais de origem animal do Alentejo, em termos quantitativos, qualitativos e diversidade, enquadrar teoricamente o tema da notoriedade no contexto do comportamento do consumidor e do marketing agro-alimentar e identificar os procedimentos metodológicos a serem utilizados e delineamento do trabalho de investigação. A análise dos dados recolhidos por inquérito, tratados com recurso a software e técnicas estatísticas descritivas, permitiram retirar conclusões relevantes, tais como a baixa notoriedade dos produtos DOP e IGP, o produto com mais notoriedade, Top-of-Mind, a Carnalentejana, entre outros. Foram identificados tanto nas fontes primárias como nas secundárias aspectos em comum: uma baixíssima notoriedade dos produtos certificados e uma preocupação e necessidade em haver mais acções de divulgação destes produtos. Dos 33 produtos certificados de origem animal do Alentejo, apuraram-se que apenas 26 se encontram a ser comercializados e em que muitos casos os agrupamentos remetem para os produtores a responsabilidade da promoção dos produtos. Foram ainda identificados tópicos para futuras pesquisas e para acções de marketing tendentes a melhorar a notoriedade dos produtos tradicionais de origem animal do Alentejo no mercado. ABSTRACT; The present work aims to know the level of renown of the traditional products of animal origin (DOP and IGP) of the Alentejo in the consumer market. This objective was reached through the realization of bibliographical revision with resource to the available secondary fountains and of primary fountains, namely of a questionnaire of evaluation of the renown of the traditional products (DOP and IGP) of animal origin of the Alentejo definitely developed for the effect. The obtained information allowed to characterize the offer of the traditional products of animal origin of the Alentejo, in quantitative, qualitative terms and diversity, to fit theoretically the subject of the renown in the context of the behavior of the consumer and of the food-rough marketing and to identify the methodological proceedings being used and delineation of the work of investigation. The analysis of the data gathered by inquiry, treated with resource the software and descriptive statistical techniques, allowed there withdrew relevant conclusions, such as the low renown of the products DOP and IGP, the product with more renown, Top-of-Mind, was the Carnalentejana, between others. Aspects were identified so much in the primary fountains how in secondary in common: a low renown of the certified products and a preoccupation and necessity in having more actions of spread/promotion of these products. Of 33 products made sure of animal origin of the Alentejo, they perfected that you punish 26 they are being marketed and in what many cases the groupings send for the producers the responsibility of the promotion of the products. Topics were still identified for future inquiries and for tending actions of marketing to improve the renown of the traditional products of animal origin of the Alentejo in the market.

The Theoretical and Experimental Tomography in the Sea Experiment (THETIS 1) took place in the Gulf of Lion to observe the evolution of the temperature field and the process of deep convection during the 1991-1992 winter. The temperature measurements consist, of moored sensors, conductivity-temperature-depth and expendable bathythermograph surveys, ana acoustic tomography. Because of this diverse data set and since the field evolves rather fast, the analysis uses a unified framework, based on estimation theory and implementing a Kalman filter. The resolution and the errors associated with the model are systematically estimated. Temperature is a good tracer of water masses. The time-evolving three-dimensional view of the field resulting from the analysis shows the details of the three classical convection phases: preconditioning, vigourous convection, and relaxation. In all phases, there is strong spatial nonuniformity, with mesoscale activity, short timescales, and sporadic evidence of advective events (surface capping, intrusions of Levantine Intermediate Water (LIW)). Deep convection, reaching 1500 m, was observed in late February; by late April the field had not yet returned to its initial conditions (strong deficit of LIW). Comparison with available atmospheric flux data shows that advection acts to delay the occurence of convection and confirms the essential role of buoyancy fluxes. For this winter, the deep. mixing results in an injection of anomalously warm water (Delta T similar or equal to 0.03 degrees) to a depth of 1500 m, compatible with the deep warming previously reported.

Recent studies concerning the landscape have investigated the most important activities that contribute for its modification and have tried to better understand the society through the marks left by its quotidian. It is understood that singular landscapes constitute the cultural patrimonies of the cities, once they are part of the daily life of the citizens and are present in their social representations. Some contemporary authors defend the preservation of the natural and urban landscape trying, specially, to keep its importance for the local population. Natal is a city where the ambient qualities are well defined and known by the beauty of the area where it is located. Situated just between a river and the sea, the city grew following its geographic characteristics. The Potengi River, the Atlantic Ocean and the vast dunes ecosystem represented natural limits to the urban expansion; at the same time they have favored the development of a landscape pattern marked by the dialectic between the natural elements and the human interventions. However, this relationship changed after the intensification of the high rising development process that took place since the 1960s. The urban legislation tried to preserve the features of the local landscape delimiting Areas for Controlling Building High , destined to protect the scenic value of some parts of the city. On the other hand, the civil construction sector has made constant pressure in sense to abolish or to modify this legal instrument, aiming profits that have increased, in the 1990s, because of the consumption and the qualification of the urban space for tourist activities. It is necessary the raising of new elements to stimulate the quarrel about the landscape preservation, the process of the urban space production and the best way for the legislation implementation. This work tries to raise elements about the subject at local level, in sense to use Natal City experience to contribute for the formulation of indicators to raise the question about the lack of measure for subjective values, for example the cultural and affective value of the landscape. The natural elements inserted in the urban profile, represent strong visual references and supply identity to the town; they are part of the collective imaginary and are detached in the social context of the city. Then, why the preservation of the landscape, that estimates the improvement in the quality of life, is not enough to justify the controlling building high already previewed as part of Natal City Legislation? These questions send us to the approach of the landscape, as a community patrimony, alerting that some of its significant esthetics attributes must be preserved as a legacy for the future generations

The principle of legality has evolved into a clear and entrenchedjurisprudential mechanism for protecting common law rights and freedoms. It operates as a shield to preserve the scope of application of fundamental rights and fre edoms. In recent years it has been increasingly applied by the courts to limit the scope of legislative provisions which potentially impinge on human rights and fundamental freedoms. Yet there is one domain where the principle of legality is conspicuously absent: sentencing. Ostensibly, this is paradoxical. Sentencing is the realm where the legalsystem operates in its most coercive manner against individuals. In thisarticle, we argue that logically the principle of legality has an importantrole in the sentencing system given the incursions by criminal sanctionsinto a number of basic rights, including the right to liberty, the freedom ofassociation and the deprivation of property. By way of illustration, we setout how the principle of legality should apply to the interpretation of keystatutory provisions. To this end, we argue that the objectives of generaldeterrence and specifi c deterrence should have less impact in sentencing. It is also suggested that judges should be more reluctant to send offenders with dependants to terms of imprisonment. Injecting the principle of legality into sentencing law and practice would result in the reduction in severity of a large number of sanctions, thereby reducing the frequency and extent to which the fundamental rights of offenders are violated. The methodology set out in this article can be applied to alter the operation of a number of legislative sentencing objectives and rules.

The popularity of mobile devices such as smart phones and tablets has led to a growing use of spatial crowdsourcing in recent years. However, current solution requires the workers send their locations to a centralized server, which leads to a privacy threat. One of the key challenges of spatial crowdsourcing is to maximize the number of assigned tasks with workers’ location privacy preserved. In this paper, we focus on the reward-based spatial crowdsourcing and propose a two-stage method which consists of constructing a differentially private contour plot followed by task assignment with optimized-reward allocation. Experiments on real dataset demonstrate the availability of the proposed method.

Recognition of multiple moving objects is a very important task for achieving user-cared knowledge to send to the base station in wireless video-based sensor networks. However, video based sensor nodes, which have constrained resources and produce huge amount of video streams continuously, bring a challenge to segment multiple moving objects from the video stream online. Traditional efficient clustering algorithms such as DBSCAN cannot run time-efficiently and even fail to run on limited memory space on sensor nodes, because the number of pixel points is too huge. This paper provides a novel algorithm named Inter-Frame Change Directing Online clustering (IFCDO clustering) for segmenting multiple moving objects from video stream on sensor nodes. IFCDO clustering only needs to group inter-frame different pixels, thus it reduces both space and time complexity while achieves robust clusters the same as DBSCAN. Experiment results show IFCDO clustering excels DBSCAN in terms of both time and space efficiency. © 2008 IEEE.

Although we have good evidence to support the notion that early intervention, prevention and community education programs can mitigate the impact of preventable disease, expanded primary health care is also being promoted by Australian governments as a panacea for reducing growth in demand generally. While preventive programs do reduce acute demand, they may not do so the extent that resources, currently allocated to the acute sector, can be substituted to provide the additional primary care services necessary to reduce acute demand permanently. These developments have particular relevance for rural and isolated communities where access to acute services is already very limited. What appears to be occurring, in rural South Australia at least, is that traditional acute services are being reduced and replaced with lower level care and social intervention programs. This is well and good, but eventually the acute care being provided in rural health units now will still need to be provided by other units elsewhere and probably at much higher cost to the system and to consumers. Where rural communities have previously managed much of their own acute service demand, they may now be forced to send patients to more distant centres for care but at much greater social and economic cost to individuals and the system.

Compared to traditional wired video sensor networks to supervise a residential district, Wireless Video-based Sensor Networks (WVSN) can provide more detail and precise information while reduce the cost. However, state-of-the-art low cost wireless video-based sensors have very constrained resources such as low bandwidth, small storage, limited processing capability, and limited energy resource. Also, due to the special sensing range of video-based sensors, cluster-based routing is not as effective as it apply to traditional sensor networks. This paper provides a novel real-time change mining algorithm based on an extracted profile model of moving objects learnt from frog's eyes. Example analysis shows the extracted profile would not miss any important semantic images to send to the Base Station for further hazards detection, while efficiently reducing futile video stream data to the degree that nowadays wireless video sensor can realize. Thus it makes WVSN available to surveillance of residential districts.

The popularity of Twitter attracts more and more spammers. Spammers send unwanted tweets to Twitter users to promote websites or services, which are harmful to normal users. In order to stop spammers, researchers have proposed a number of mechanisms. The focus of recent works is on the application of machine learning techniques into Twitter spam detection. However, tweets are retrieved in a streaming way, and Twitter provides the Streaming API for developers and researchers to access public tweets in real time. There lacks a performance evaluation of existing machine learning-based streaming spam detection methods. In this paper, we bridged the gap by carrying out a performance evaluation, which was from three different aspects of data, feature, and model. A big ground-truth of over 600 million public tweets was created by using a commercial URL-based security tool. For real-time spam detection, we further extracted 12 lightweight features for tweet representation. Spam detection was then transformed to a binary classification problem in the feature space and can be solved by conventional machine learning algorithms. We evaluated the impact of different factors to the spam detection performance, which included spam to nonspam ratio, feature discretization, training data size, data sampling, time-related data, and machine learning algorithms. The results show the streaming spam tweet detection is still a big challenge and a robust detection technique should take into account the three aspects of data, feature, and model.
