Combining Knowledge- and Corpus-based Word-Sense-Disambiguation Methods

In this paper we concentrate on the resolution of the lexical ambiguity that arises when a given word has several different meanings. This specific task is commonly referred to as word sense disambiguation (WSD). The task of WSD consists of assigning the correct sense to words using an electronic dictionary as the source of word definitions. We present two WSD methods based on two main methodological approaches in this research area: a knowledge-based method and a corpus-based method. Our hypothesis is that word-sense disambiguation requires several knowledge sources in order to solve the semantic ambiguity of the words. These sources can be of different kinds--- for example, syntagmatic, paradigmatic or statistical information. Our approach combines various sources of knowledge, through combinations of the two WSD methods mentioned above. Mainly, the paper concentrates on how to combine these methods and sources of information in order to achieve good results in the disambiguation. Finally, this paper presents a comprehensive study and experimental work on evaluation of the methods and their combinations

The Edward Bliss Emerson Journal Project: Qualitative Research by a Non-Hierarchical Team

Edward Bliss Emerson (1805-1834), a younger brother of the renowned essayist and poet Ralph Waldo Emerson, lived in the Caribbean for the final three years of his life. His journal and letters are a rich manuscript source for the history of the Danish Virgin Islands (1831-1832) and Puerto Rico (1831-1834). The texts also reflect the contemporary political and cultural situation in the United States, and Edward\u27s search for health, economic independence, intellectual stimulation and metaphysical fulfillment. These writings ignited an intellectual passion in José G. Rigau-Pérez, a physician, medical epidemiologist, and historian in Puerto Rico. Furthering access to these unique resources he produced a digital version of the journal from the Ralph Waldo Emerson Memorial Association deposit at the Houghton Library (Harvard University, Cambridge, Massachusetts) and the letters kept at Houghton Library, the Emerson Family Papers at Massachusetts Historical Society (Boston), and other locations. (See http://edicionesdigitales.info/biblioteca/Emerson.pdf for the full online text of the journal and letters). Dr. José G. Rigau-Pérez also organized a community of scholars who share a sense a common purpose even in the absence of propinquity. The group includes Silvia E. Rabionet, an associate professor in health education at the University of Puerto Rico School of Public Health and Nova Southeastern University College of Pharmacy; Annette B. Ramírez de Arellano, a planner and policy analyst whose work focuses on public health; Wilfredo A. Géigel, a trial lawyer by profession, an independent scholar, member and past president of the Society of Virgin Islands Historians, and Adjunct Professor of History at the University of the Virgin Islands, St. Croix Campus; Raúl Mayo-Santana, an Ad-Honorem Professor at the School of Medicine, University of Puerto Rico; and Alma Simounet, a Professor of English and Linguistics at the University of Puerto Rico. They explore the Emerson journal and letters from multidisciplinary perspectives to bring forth historical, medical, legal, sociological, and geographical insights of the people, times, and places of the mid 1830s in the Caribbean and United States. The work of this talented team resulted in a series of essays we at The Qualitative Report (TQR) are pleased to present as our first book -The Edward Bliss Emerson Journal Project: Qualitative Research by a Non-Hierarchical Team! Under the editorial guidance of TQR Editor Dan Wulff, Dr. Rigau-Pérez and the other members of the team have produced these unique accounts as a transdisciplinary examination of Emerson\u27s world.https://nsuworks.nova.edu/tqr_books/1001/thumbnail.jp

Qualitative Research by a Non-Hierarchical Team

In this and subsequent issues, The Qualitative Report will publish eight articles about a journal written by Edward B. Emerson (1805-1834), a younger brother of American philosopher and writer Ralph Waldo Emerson. This introduction will describe the origins of the project, the sources, the process and the outcomes of the collaboration. The authors hope to document and illustrate the richness and value of interdisciplinary qualitative inquiry, while providing specifics of how the Emerson Journal Project evolved. We provide examples to illustrate the characteristics of effective teamwork, but also present the challenges along the way and how they were surmounted. The breadth of the topics in the journal and the range of expertise within the team have resulted in the use of different approaches to examine Emerson’s text. It is the authors’ goal that these essays will enhance the reading of Emerson´s journal, while contributing to the social and historical understanding of the Caribbean

Endurance, Refuge, and Reemergence of Dengue Virus Type 2, Puerto Rico, 1986–2007

To study the evolution of dengue virus (DENV) serotype 2 in Puerto Rico, we examined the genetic composition and diversity of 160 DENV-2 genomes obtained through 22 consecutive years of sampling. A clade replacement took place in 1994–1997 during a period of high incidence of autochthonous DENV-2 and frequent, short-lived reintroductions of foreign DENV-2. This unique clade replacement was complete just before DENV-3 emerged. By temporally and geographically defining DENV-2 lineages, we describe a refuge of this virus through 4 years of low genome diversity. Our analyses may explain the long-term endurance of DENV-2 despite great epidemiologic changes in disease incidence and serotype distribution

Dengue fever in pregnancy: a case report

<p>Abstract</p> <p>Background</p> <p>Dengue, a mosquito-borne flavivirus infection, is endemic in Southeast Asia. Currently, the incidence has been increasing among adults.</p> <p>Case presentation</p> <p>A 26-year-old Thai woman, G₁P₀ 31 weeks pregnancy, presented with epigastric pain for 1 day. She also had a high-grade fever for 4 days. The physical examination, complete blood counts as well as serology confirmed dengue fever. The patient was under conservative treatment despite severe thrombocytopenia. She was well at the 3^rd day of discharge and 1-week follow-up. The pregnancy continued until term without any complication and she delivered vaginally a healthy female baby.</p> <p>Conclusions</p> <p>More cases of dengue infection in pregnancy can be found due to the increasing incidence during adulthood. It should be suspected when a pregnant woman presents with symptoms and signs like in a non-pregnant. Conservative treatment should be conducted unless there are any complications.</p

Melatonin affects the motility and adhesiveness of in vitro capacitated boar spermatozoa via a mechanism that does not depend on intracellular ROS levels

This work sought to address the effects of melatonin during in vitro capacitation (IVC) and progesterone-induced acrosome exocytosis (IVAE) in boar spermatozoa. With this purpose, two different experiments were set. In the first one, IVC and IVAE were induced in the absence or presence of melatonin, which was added either at the start of IVC or upon triggering the IVAE with progesterone. Different parameters were evaluated, including intracellular levels of peroxides and superoxides, free cysteine radicals and distribution of specific lectins. While melatonin neither affected most capacitation-associated parameters nor IVAE, it dramatically decreased sperm motility, with a maximal effect at 5 µm. This effect was accompanied by a significant increase in the percentage of agglutinated spermatozoa, which was independent from noticeable changes in the distribution of lectins. Levels of free cysteine radicals were significantly lower in melatonin treatments than in the control after 4 h of incubation in capacitating medium. The second experiment evaluated the effects of melatonin on in vitro fertilising ability of boar spermatozoa. Spermatozoa previously subjected to IVC in the presence of 1 µm melatonin and used for in vitro fertilisation exhibited less ability to bind the zona pellucida (ZP) and higher percentages of monospermy. In conclusion, melatonin affects sperm motility and the stability of nucleoprotein structure and also modulates the ability of in vitro capacitated boar spermatozoa to bind the oocyte ZP. However, such effects do not seem to be related to either its antioxidant properties or changes in the sperm glycocalix

Dengue Deaths in Puerto Rico: Lessons Learned from the 2007 Epidemic

Dengue is a major public health problem in the tropics and subtropics; an estimated 50 million cases occur annually and 40 percent of the world's population lives in areas with dengue virus (DENV) transmission. Dengue has a wide range of clinical presentations from an undifferentiated acute febrile illness, classic dengue fever, to severe dengue (i.e., dengue hemorrhagic fever or dengue shock syndrome). About 5% of patients develop severe dengue, which is more common with second or subsequent infections. No vaccines are available to prevent dengue, and there are no specific antiviral treatments for patients with dengue. However, early recognition of shock and intensive supportive therapy can reduce risk of death from ∼10% to less than 1% among severe dengue cases. Reviewing dengue deaths is one means to identify issues in clinical management. These findings can be used to develop healthcare provider education to minimize dengue morbidity and mortality
