A Piece of a Puzzle of Haplotypes for the Indian Ocean Hawksbill Turtle  [PDF]
Rita Anastácio, Mário Jorge Pereira
Natural Resources (NR) , 2017, DOI: 10.4236/nr.2017.88034
Abstract: The Indian Ocean basin has much to reveal in what concerns marine turtles. Its regional management units (RMUs) are still lacking molecular data to define conservation strategies and priorities. Vamizi Island is one of the best known rookeries in the north of the Mozambique Channel. A mitochondrial DNA analysis revealed 14 haplotypes for the hawksbill turtle’s nesting and foraging in/near Vamizi, twelve of which were new in 2011. Though more studies inside the Channel are needed, Vamizi Island possibly contributes with hatchlings for other locations. More knowledge is important to define priorities for management units inside the Indian Ocean.
From the Challenges Imposed by Climate Change to the Preservation of Ecosystem Processes and Services  [PDF]
Rita Anastácio, Mário Jorge Pereira
Natural Resources (NR) , 2017, DOI: 10.4236/nr.2017.812048
Today, especially in countries that offer a satisfactory quality of life, it is easy to forget that we depend directly and indirectly on services provided by ecosystems such as quantity and quality of water, energy, food, health, and shelter. In less developed countries, the daily struggle for essential goods makes this dependency more real, despite the lack of knowledge, organization and/or financial resources to deal with the problems imposed on ecosystems by climate and anthropogenic changes. Protecting ecosystems by ensuring the services they provide has become highly dependent on our management capacity, our understanding of its functioning, and our capacity for persuasion. Demographic pressure and individualism compromise the survival of various species, including our own, and create pressures under governments and the stability of nations. The notion of facing a global challenge has awakened in the scientific community the need to focus on developing global strategies that change the mind-sets of decision makers, industry, governments and markets. Global knowledge networks and experts are being built to mitigate problems on a global scale. In this mini review, the authors make a brief visit to documents, intergovernmental initiatives, and platforms that have been built with the aim of contributing to promote a resolution for the global problems.
The History of Aviation Education and Training  [PDF]
Jorge M. M. Barata, Fernando M. S. P. Neves
Open Journal of Applied Sciences (OJAppS) , 2017, DOI: 10.4236/ojapps.2017.74017
Abstract: Aviation education and training began early in the 20th century just after the first successful powered flight of the Wright brothers. In the present paper, the types of aviation education and training around the world are reviewed. Its developments were distinct in many different countries, and in some cases evolved from the military needs while in others from the dedication of a few enthusiasts. In the 21st century aeronautical and aerospace engineering is taught at the most advanced engineering schools in the world providing skills and competences that integrate advanced disciplines.
Bottom-Up Approach towards a Human Wellbeing Assessment for the Design of a Management Plan: A Study Case with Contributions to Improve Sustainable Management of Resources in a Northern Area of Mozambique  [PDF]
Rita Sofia Anastácio, Lúcia Nunes Schertenleib, Jorge Paiva, Jorge Ferr?o, Mário Jorge Pereira

The loss of biodiversity and ecosystem services disturbance will result in serious ecological and socioeconomic consequences. How can people be prepared to be more efficient in preserving ecosystems, its services and resources? The Messalo Wilderness Area (MWA) is an area lacking a bottom-up approach for the design of a management plan. This research intended to develop a strategy to gather people’s views to begin a human wellbeing assessment for the area, for which a Digital Questionnaire (DQ) was developed and tested. The specific objectives were to 1) verify the dispersion/distribution of people and elephants; 2) study the natural resources used by the inhabitants; 3) locate the areas from where the most important natural resources are extracted and where conflict between humans and animals occur; 4) propose a Management Plan (MP) capable of mitigating the human-animals conflict, promoting the conservation of elephants and, consequently, of other types of biodiversity, thus working towards a better socio-economical development of the area. The elements gathered in the consulted references were used to design several maps and cartographic figures shown in this article, using the Map Window software. These maps describe: fresh water distribution, habitat distribution, population dispersal and main road connections, crop fields distribution and main exploitation spots of the different resources, orography and topography. The results from the DQ analysis helped to gather indicators to the human wellbeing assessment. The information gathered in the literature and by inquiry was effective in confirming the high dependency of local people on land and sea resources, as well as the conflicts between people and wild animals, such as elephants and African wild dogs, and the reasons for those conflicts. The DQ is effective in gathering people’s opinions and it constitutes an important tool in a bottom-up approach to the design of a management plan as to the design of the MP for the MWA.

?Rumores, miedo o epidemia? La peste de 1913 y 1914 en la costa atlántica de Colombia
Márquez Valderrama, Jorge;
História, Ciências, Saúde-Manguinhos , 2001, DOI: 10.1590/S0104-59702001000200007
Abstract: by the end of the 1800s , international trade and steam navigation made way for the third bubonic plague pandemy, which started in china in 1891 and reached america in 1898. this calamity apparently arrived in colombia's coast between 1913 and 1915, during the apex of pasteur medicine. the deficiencies of colombian public scientific and sanitary apparat, concerning the emerging bacteriology and epidemiology, prevented the government and the medical body from reacting against the fear and rummor of epidemy, which negatively affected the trade. the authorities were also unable to fight this problem with adequate diagnosis, enferms treatment, urban sanitation, and isolation of infected places. these difficulties led to a confrontation between the government and the medical body, inciting an argument about the existence of the plague. this discussion was settled by the north american official medicine that, in its verdict, gave preference to the commercial interests of the united states, ignoring the sanitary urgencies of the colombian atlantic coast.

Rearme y baja percepción de amenaza interestatal en Sudamérica. ?Es posible tal coexistencia?
Battaglino, Jorge M.;
Perfiles latinoamericanos , 2010,
Abstract: the purpose of this article is to critically analyze the use of the concept of rearmament to explain the purchases of arms in south america. the use of this term has not only contributed to the conceptual confusion but also to a risky political use of it. the concept rearmament has a specific historical meaning which is often link to situations of acute perceptions of threat among states and to the imminent break of war. from a theoretical and empirical perspective, neither the historical understanding of the concept nor its empirical referents are present in the region.
An analysis of the importance of appropriate tie breaking rules in dispatch heuristics
Valente, Jorge M. S.;
Pesquisa Operacional , 2006, DOI: 10.1590/S0101-74382006000100009
Abstract: in this paper, we analyse the effect of using appropriate tie breaking criteria in dispatch rules. we consider four different dispatch procedures, and for each of these heuristics we compare two versions that differ only in the way ties are broken. the first version breaks ties randomly, while the second uses a criterion that incorporates problem-specific knowledge. the computational results show that using adequate tie breaking criteria improves the performance of the dispatch heuristics. the magnitude of the improvement is different for the four heuristics, and also depends on the characteristics of each specific instance. the use of problem-related knowledge for breaking ties should therefore be given some consideration in the implementation of dispatch rules.
Mortalidad Infantil en Chile: 1989-1998
Szot M.,Jorge;
Revista chilena de pediatría , 2002, DOI: 10.4067/S0370-41062002000200009
Abstract: since 1960 infant mortality (im) in chile has decreased owing to multiple factors. this paper aims to compare the im rate and its causes between 1989 and 1998 in chile. using a time sequence study, im data was obtained from the demographic annual reports of the national institute of statistics. results: a 40% reduction in the total number of deaths (5,183 vs less than 2,793 in 1989 and 1998 respectively). the main causes of death were perinatal pathology, malformations and respiratory diseases. specific causes of death were pneumonia and immaturity. conclusions: in chile the so called "avoidable deaths" account for most of the im during the 90s, hence it is important to continue making efforts to prevent them
