Educa o, Geografia e o desafio de novas tecnologias
Angelica Carvalho Di Maio,Alberto W. Setzer
Revista Portuguesa de Educa??o , 2011,
Abstract: The objective of this work was to report a new stage that is taking place in Geography education, associated to the use of new digital technologies, as perceived in the current literature. This situation characterizes a condition where teachers and students walk side by side towards knowledge access. For many teachers in Brazil, computer tools are still a little known option of work, that causes fear and distance, for the pupils, that are contemporaries of computer applications, such new options do not constitute mysteries and dreads. Therefore, it is the education sector responsibility to create the suitable conditions so that teachers and students benefit from the new technologies to foster education and learning.

PERCEP O AMBIENTAL NA áREA DE PROTE O AMBIENTAL DE MACAé DE CIMA: PERSPECTIVAS PARA O ECOTURISMO
Aurea Pinheiro Rocha,Angelica Carvalho Di Maio,Leonardo Gama Campos
Revista Brasileira de Ecoturismo , 2011,
Abstract: A área de Prote o Ambiental de Macaé de Cima (APAMC), localizada no distrito de Lumiar em Nova Friburgo, RJ, criada em 2001, vem passando por conflitos devido ao choque de diferentes vis es, quanto ao seu uso, desde sua implanta o. Além disso, esta área enfrenta muitas transforma es sócio-econ micas agravadas pela chegada do turismo e pela desvaloriza o das práticas agrícolas tradicionais. Os conflitos em rela o ao uso da terra vêm demonstrando na regi o os interesses divergentes dos atores sociais envolvidos na implanta o desta modalidade de unidade de conserva o. O ator social que desponta nesse cenário ainda recente, s o pessoas ligadas às atividades turísticas e que fortemente tem contribuído para mudan as da estrutura sócio-espacial, ligadas principalmente ao novo uso do solo. Baseando-se nos pressupostos de como o turismo vem interagindo e transformando antigas atividades econ micas e como vem se fortalecendo como uma nova atividade, com seus interesses, dificuldades e impactos busca-se analisar na pesquisa as quest es socioambientais existentes na APAMC, através da percep o dos diferentes grupos de atores sociais (agricultores, turistas, conselho gestor da APA), orientadas ao ecoturismo. Os instrumentos da pesquisa foram entrevistas estruturadas e semi-estruturadas, recursos de imagens (oficinas, mapas mentais) e questionários com os atores envolvidos com APAMC, baseando-se nos métodos qualitativos de obten o e interpreta o dos dados. Na perspectiva da popula o local, a chegada do turismo representa uma nova possibilidade de renda frente à um declínio da agricultura da regi o. Entretanto, esse acelerado crescimento, numa localidade antes “acostumada” com o modo de vida tipicamente rural pode apresentar desafios em rela o à infra-estrutura, além da própria inser o da popula o local nessas novas atividades. Os turistas, geralmente de passagem, n o têm contato com a realidade da regi o, ent o querem o “espa o verde” como fonte de prazer e n o de subsistência como os agricultores nativos, sendo os primeiros, indivíduos essencialmente urbanos. Os valores trazidos dos centros urbanos v o se mesclando com os valores tradicionais, sendo os últimos muitas vezes substituídos pelos primeiros. O planejamento do setor turístico na regi o ainda é insuficiente já que carece de diretrizes específicas, visto que o plano de manejo da APA ainda n o foi terminado e os órg os públicos responsáveis n o atuam de maneira satisfatória. Há muitos problemas a serem superados para que uma verdadeira a o prática do ecoturismo possa fluir, principalmente quando
A Robust Indicator for Promoting Circular Economy through Recycling  [PDF]
Francesco Di Maio, Peter Carlo Rem
Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.610096
Abstract: In order to move towards a more sustainable development, it is necessary not only to minimize the use of materials in the design stage and to find new materials as alternatives to nonrenewable ones (e.g. optical fiber instead of copper, biopolymers instead of polymers from oil) but also to reclaim as much as possible material value through effective recycling. To this extent, recycling can play a key role in multiple dimensions, while providing new business opportunities for innovative companies, having positive impacts on the society and the environment and fostering an effective circular economy as well. Because of the advanced waste management infrastructures available in developed countries, it is possible to achieve an almost complete collection of solid wastes into a variety of controlled bulk material flows. However, the picture for the follow-up step, the recycling of raw materials such as steel, non-ferrous metals, polymers and glass from these flows, is less positive. Materials value recovered from waste represents a very small fraction of European GDP. The fundamental issue is that policymakers still lack an effective key performance indicator for stimulating the recycling industry. Therefore although recycling plays an important role in the circular economy perspective, it is necessary to radically change the metric used so far to compute the recycling rate. Nowadays, the recycling rate is computed measuring the amount of material entering the recycling facilities. This approach has brought about an inaccurate and somehow misleading indicator (the recycling rate) which contributed to wrong decision making and to poor innovation in the industry. The new approach proposed in this paper considers the use of a Circular Economy Index (CEI) as the ratio of the material value produced by the recycler (market value) by the intrinsic material value1 entering the recycling facility. It is argued that this index is related to strategic, economic and environmental aspects of recycling and it has very important implications as decision making tool. To compute the CEI it is necessary to know detailed information of the components and materials contained in each end of life (EOL) product entering the recycling facilities and how they end up in the recycled raw materials. Therefore an accurate accounting of materials (with standards if available), mass, chemical composition and smallest dimension (e.g. a screw, a plastic foil) is proposed.
Towards a Reference Model for Open Access and Knowledge Sharing, Lessons from Systems Research
Paola Di Maio
International Journal of Computer Science Issues , 2011,
Abstract: The Open Access Movement has been striving to grant universal unrestricted access to the knowledge and data outputs of publicly funded research. leveraging the real time, virtually cost free publishing opportunities offered by the internet and the web. However, evidence suggests that in the systems engineering domain open access policies are largely ignored. This paper presents the rationale, methodology and results of an evidence based inquiry that investigates the dichotomy between policy and practice in Open Access (OA) of systems engineering research in the UK, explores entangled dimensions of the problem space from a socio-technical perspective, and issues a set of recommendations, including a reference model outline for knowledge sharing in systems research.
Knowledge Audit Framework

Bootstrap and Order Statistics for Quantifying Thermal-Hydraulic Code Uncertainties in the Estimation of Safety Margins
Enrico Zio,Francesco Di Maio
Science and Technology of Nuclear Installations , 2008, DOI: 10.1155/2008/340164
Abstract: In the present work, the uncertainties affecting the safety margins estimated from thermal-hydraulic code calculations are captured quantitatively by resorting to the order statistics and the bootstrap technique. The proposed framework of analysis is applied to the estimation of the safety margin, with its confidence interval, of the maximum fuel cladding temperature reached during a complete group distribution blockage scenario in a RBMK-1500 nuclear reactor.
Quality of Life in elderly patients with cancer
Massimo Di Maio, Francesco Perrone
Health and Quality of Life Outcomes , 2003, DOI: 10.1186/1477-7525-1-44
Abstract: In conclusion, some steps have been done in clinical cancer research dedicated to elderly patients, and the role of QOL assessment in this setting is important. However, many methodological problems must be resolved, in order to obtain reliable and useful results. A QOL assessment could also be useful for elderly patients in clinical practice, where it could improve patient-clinician communication: a wider application of properly selected instruments should be recommended.If current incidence rates will not decrease, in the next fifty years the number of people diagnosed with cancer is expected to double, solely due to the progressive ageing of the population [1]. Ageing is rapidly affecting the median age of all Western populations, mostly due to the reduction in birthrate, coupled with the increased life expectancy (figure 1). This demographic phenomenon is rapidly increasing the number of people who are diagnosed and treated for cancer, because the incidence of most types of cancers is age-dependent and the risk of developing a tumor is progressively higher with increasing age [2].Elderly patients present peculiar characteristics [3,4] that make the choice of the correct treatment more difficult, often exposing these patients to the risk of being undertreated [5]. Although chronological age is not necessarily equivalent to biological age, ageing determines physiological changes in organ functions and pharmacokinetics. Furthermore, concomitant diseases are very frequent, significantly affecting the functional status and the general health condition, in addition to tumor symptoms. Therefore, a correct approach to elderly people with cancer should not leave out a comprehensive geriatric assessment, in the attempt to better predict the prognosis of the patient and the risks associated with specific treatments [6].Despite the universal recognition of the importance of clinical trials to inform clinical practice and to guide therapeutic decisions, it has been repeatedl
