NVODS and the Development of OPeNDAP
Peter Cornillon,Jennifer Adams,M. Benno Blumenthal,Eric Chassignet
Oceanography , 2009,
Abstract: The National Oceanographic Partnership Program (NOPP) funded a project to develop the foundation for a National Virtual Ocean Data System (NVODS) that has resulted in a robust data access framework for the exchange of oceanographic data (the Open source Project for a Network Data Access Protocol, or OPeNDAP) and a broad community of ocean data providers that remains vigorous and growing five years after NOPP funding ended. The project produced a number of "lessons learned" related to the design and implementation of distributed data systems that can inform other related efforts. These lessons are presented along with a brief overview of OPeNDAP and summaries of a number of projects that depend on OPeNDAP for data distribution.
An online operational rainfall-monitoring resource for epidemic malaria early warning systems in Africa
Emily Grover-Kopec, Mika Kawano, Robert W Klaver, Benno Blumenthal, Pietro Ceccato, Stephen J Connor
Malaria Journal , 2005, DOI: 10.1186/1475-2875-4-6
Abstract: Rainfall is one of the major factors triggering epidemics in warm semi-arid and desert-fringe areas. Explosive epidemics often occur in these regions after excessive rains and, where these follow periods of drought and poor food security, can be especially severe. Consequently, rainfall monitoring forms one of the essential elements for the development of integrated Malaria Early Warning Systems for sub-Saharan Africa, as outlined by the World Health Organization.The Roll Back Malaria Technical Resource Network on Prevention and Control of Epidemics recommended that a simple indicator of changes in epidemic risk in regions of marginal transmission, consisting primarily of rainfall anomaly maps, could provide immediate benefit to early warning efforts. In response to these recommendations, the Famine Early Warning Systems Network produced maps that combine information about dekadal rainfall anomalies, and epidemic malaria risk, available via their Africa Data Dissemination Service. These maps were later made available in a format that is directly compatible with HealthMapper, the mapping and surveillance software developed by the WHO's Communicable Disease Surveillance and Response Department. A new monitoring interface has recently been developed at the International Research Institute for Climate Prediction (IRI) that enables the user to gain a more contextual perspective of the current rainfall estimates by comparing them to previous seasons and climatological averages. These resources are available at no cost to the user and are updated on a routine basis.It is estimated that more than 110 million Africans live in areas prone to epidemics of malaria. Populations in these areas are infrequently challenged by malaria and, therefore, do not fully develop acquired immunity. As a result, the disease remains life threatening to all age groups. The impact of malaria epidemics could be greatly reduced by timely detection or, ideally, by prediction and prevention through
Web-based climate information resources for malaria control in Africa
Emily K Grover-Kopec, M Benno Blumenthal, Pietro Ceccato, Tufa Dinku, Judy A Omumbo, Stephen J Connor
Malaria Journal , 2006, DOI: 10.1186/1475-2875-5-38
Abstract: Malaria remains a major public health threat to the African continent and its control is critical to achieving the Millennium Development Goals in this region. The recently published Global Strategic Plan for Roll Back Malaria 2005–2015 has stated that "Six out of eight Millennium Development Goals can only be reached with effective malaria control in place" [1]. The greatest burden of malaria in Africa is born by populations in regions where the disease pathogen is perennially present in the community. In these regions, the environment is conducive to interactions between the Anopheles mosquito, malaria parasites and human hosts because they contain surface water in which mosquitoes can lay their eggs, humid conditions which facilitate adult mosquito life spans of adequate length, and relative warmth which allows both the mosquito and the malaria parasite to develop rapidly. In addition, housing quality is generally poor and offers little protection from human-mosquito interaction. Those most vulnerable to endemic malaria are young children (<5 years of age) who have yet to acquire disease immunity, pregnant women, whose immunity is reduced, and non-immune migrants or travelers.Epidemic malaria tends to occur along the geographical margins of the endemic regions, when the conditions supporting the equilibrium between the human, parasite and mosquito vector populations are disturbed. This leads to a sharp but temporary increase in disease incidence. More than 124 million Africans live in such areas and experience epidemics causing around 12 million malaria episodes and up to 310,000 deaths annually [2]. In these regions, an individual's exposure to malaria is infrequent and, therefore, little acquired immunity to this life threatening disease is developed. All age groups are, therefore, vulnerable to epidemic malaria [3]. The development of an online product that supports epidemic risk monitoring has been previously reported [4].While economic development has played
Metastatic malignant melanoma arising in the ovary: A case report and review of the literature  [PDF]
Amani Harris, Norman Blumenthal
Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.37A1002

Introduction: This article is a case report of metastatic malignant melanoma to the ovary and a review of the current literature on recommendations for diagnosis and management. Background: Metastatic involvement of the ovary from malignant melanoma is relatively uncommon and represents a diagnostic challenge. There are 74 cases of malignant melanoma metastasing to the ovary reported in the English literature. Malignant melanoma in the ovary is often found at autopsy, as a part of an extensive multisystemic spread of the disease and is rarely diagnosed during life. Most cases reported in the literature thus far occurred in women of reproductive age. Commonly, the history of a primary cutaneous melanoma lesion is remote, and in some cases, absent [1]. Most cases are associated with disseminated disease and carried a dismal prognosis [2].

A volume-based approach to the multiplicative ergodic theorem on Banach spaces
Alex Blumenthal
Mathematics , 2015, DOI: 10.3934/dcds.2016.36.2377
Abstract: A volume growth-based proof of the Multiplicative Ergodic Theorem for Banach spaces is presented, following the approach of Ruelle for cocycles acting on a Hilbert space. As a consequence, we obtain a volume growth interpretation for the Lyapunov exponents of a Banach space cocycle.
Learning and Teaching Qualitative Research Methods in Social Science. Provisional Reflections Lehren und Lernen Qualitativer Forschungsmethoden in den Sozialwissenschaften. Vorl ufige überlegungen Aprendizaje y ense anza de métodos cualitativos de investigación en ciencias sociales – Reflexiones provisionales
Benno Herzog
Forum : Qualitative Social Research , 2008,
Abstract: This article aims to resume and give structure to the debate about "teaching and learning qualitative methods in social sciences" (http://www.qualitative-research.net/index.php/fqs/about/editorialPolicies#deb), which is currently taking place in the trilingual journal Forum Qualitative Sozialforschung / Forum: Qualitative Social Research. The core of the debate is composed, at the moment, by nine texts with different characteristics, with authors in different academic positions and with very diverse approaches. The aim of this presentation is to open the debate to Ibero-America and to invite Hispanic students, teachers, researchers and professionals to participate and to enrich the discussion with their experiences and reflections. The text starts by explaining the rise of the debate during one particular conference in Germany (http://www.berliner-methodentreffen.de/) and by pointing out different links with other questions related to qualitative research. Short reviews of the contributions are presented in three sections: background, theoretical contributions, and experiences. Finally, four main topics are identified to occur in the actual discussion: the social context of teaching and learning, epistemological models and their implication for the teaching process, specific didactic models and experiences for qualitative research and, finally, the role of the researcher as teacher and student and his/her personal "compatibility" with qualitative methods. URN: urn:nbn:de:0114-fqs0803220 Die vorliegende Ausarbeitung fasst die Debatte zum "Lehren und Lernen qualitativer Methoden" (http://www.qualitative-research.net/index.php/fqs/about/editorialPolicies#deb) zusammen, welche sich in letzter Zeit im Rahmen der dreisprachigen Online-Zeitschrift "Forum Qualitative Sozialforschung / Forum: Qualitative Social Research" (FQS) entwickelt hat. Der Kern der eigentlichen Debatte besteht (zurzeit) aus neun Beitr gen unterschiedlicher Textgattungen, von Autoren und Autorinnen aus verschiedenen Positionen innerhalb des akademischen Feldes und mit unterschiedlichen Fragestellungen. Ziel des Artikels ist es, die Debatte für die spanischsprachige Welt zug nglich zu machen und somit Studierende, Dozent/innen, Sozialforscher/innen und Fachleute dieser L nder einzuladen, an der Diskussion teilzunehmen und diese durch ihre Erfahrungen und überlegungen zu bereichern. Zuerst wird das Entstehen der Debatte im Rahmen des "Berliner Methodentreffens Qualitative Forschung" (http://www.berliner-methodentreffen.de/) erl utert und ihre verschiedenen Verbindungen zu anderen Fragestellun
Economics of Sports: A Note to this Special Issue
Benno Torgler
Economic Analysis and Policy , 2009,
Abstract: : The expansion of economics to other spheres of life, including politics, war, crime, religion, or in particular sports can be seen in line with Hirshleifer (2002) as a breath of fresh air in economics. Although one can always criticize the generalizability of results developed with sports data, sporting events can still be seen as economic (miniature) environments. There is no reason not to acknowledge that athletes, for example, behave according to two key elements in economics, namely incentives and constraints. Focal economic concepts such as prices, opportunity costs or property rights can be nicely investigated in sports markets and are supposed to drive the behaviour of their key actors. An essential strength of sports events is the fact that they take place in a controlled environment generating therefore outcomes that come very close to holding other things equal, providing therefore a real-world laboratory for testing economic theories. Researchers have the chance of working with highly reliable data (low variable errors) and reduced omitted variables biases. The advantages can be visualized using the Tour de France as an example. The ranking of a cyclist at the Tour de France, his performance in the mountains or the time trials are clearly observable and are free of discrepancies compared to well known and often used traditional economic variables such as GDP or CPI. Statistics can be adjusted based on the outside conditions (stadium, weather conditions etc.). A Tour de France takes place in a controlled environment. All riders perform in the same terrain at the same time with the same outside restrictions such as the weather. Further external influences are controlled by the rules (law) of the event, as they are the same for all riders. Thus, many factors can be held constant and therefore the situation is much like a controlled environment. Even though a cycling event allows social and economic interactions and is thus less controlled than a laboratory experiment one of the main advantages is that the participation evokes actual and real processes (e.g., strong monetary incentives) in an environment outside a laboratory setting (Goff and Tollison 1990).
Introduction to the Special Issue on Tax Compliance and Tax Policy
Torgler, Benno
Economic Analysis and Policy , 2008,
Abstract: A man once wrote to the Australian Taxation Office: ‘I have been unable to sleep, knowing that I have cheated on my income tax. I understated my taxable income and now enclose a cheque for $1500. If I still can’t sleep, I will send you the rest’. The joke illustrates neatly how taxation and tax compliance is of crucial importance in citizens’ lives. In his book For Good and Evil, Charles Adams (1993) predicts: ‘Though tax records are generally looked upon as a nuisance, the day may come when historians will realise that tax records tell the real story behind civilised life. How people were taxed, who was taxed, and what was taxed tell more about a society than anything else’ (p. 21). Our first EAP issue in 2008 accordingly starts with a special volume on tax compliance and tax policy. We have assembled a collection of contributions from leading international researchers in this area. The studies will show that the topic is at once complex, challenging, and fascinating.
