Towards the automatic merging of language resources

Language Resources are a critical component for Natural Language Processing applications. Throughout the years many resources were manually created for the same task, but with different granularity and coverage information. To create richer resources for a broad range of potential reuses, nformation from all resources has to be joined into one. The hight cost of comparing and merging different resources by hand has been a bottleneck for merging existing resources. With the objective of reducing human intervention, we present a new method for automating merging resources. We have addressed the merging of two verbs subcategorization frame (SCF) lexica for Spanish. The results achieved, a new lexicon with enriched information and conflicting information signalled, reinforce our idea that this approach can be applied for other task of NLP.

Measuring Instruments In Cardiology Adapted Into Portuguese Language Of Brazil: A Systematic Review

This was a systematic review aimed at identifying and characterizing measuring instruments, developed in the context of cardiology, which were adapted into Portuguese language of Brazil. Systematic searches were performed in six databases. Information extracted included cultural adaptation process and measurement properties. To assess the methodological quality of studies, criteria based on international guidelines for cultural adaptation of instruments were used. Among the 114 articles found, 14 were eligible for review. Of these, most evaluated quality of life (35.7%) and health knowledge/learning (28.6%). Most studies followed all stages of the adaptation process recommended in the literature. With respect to measurement properties, internal consistency, verified by Cronbach’s alpha, was the property reported in the majority of the studies, as well as construct and criterion validity. This study is expected to provide to the scientific community a critical evaluation of adapted questionnaires available in the context of cardiology.


Critical appraisal of single port access cholecystectomy.

BACKGROUND: Single port access (SPA) cholecystectomy is a new concept in laparoscopic surgery. A review of existing results was performed to evaluate critically the current state of SPA with specific reference to feasibility, safety, learning curve, indications and cost-effectiveness. METHODS: All papers identified in MEDLINE until 15 February 2010 and all other relevant papers obtained from cited references were reviewed, without any language restriction. Case reports and series of fewer than three patients were excluded. RESULTS: After selection, 24 studies including 895 patients were analysed. None was randomized. Feasibility seems to be established, with a conversion rate of 2 per cent. SPA was not standardized and there was much technical variation. The learning curve could not be determined. Median follow-up time was 3 (range 0.25-12) months. The overall published complication rate was 5.4 per cent and the biliary complication rate 0.7 per cent. The rate of umbilical complications ranged from 2 to 10 per cent. CONCLUSION: SPA cholecystectomy seems feasible, but standardization, safety and the real benefits for patients need further assessment. Uncontrolled wide adoption of this approach may be responsible for a rise in biliary complications.

Understanding the Many Faces of Child Neglect: A Review of Denial of Critical Care Cases in Iowa, 2005

In recent years, Iowa leaders and the general public have focused on the abuse children have suffered from several causes, including sexual abuse, methamphetamine manufacturing, and serious physical injury. While this public attention and concern is welcome, the harm that children suffer from neglect, which Iowa law calls denial of critical care, has received little attention, despite representing almost three-quarters of all child abuse cases. With financial assistance from the Greater Des Moines Community Foundation in 2003-2004, Prevent Child Abuse Iowa started a Child Neglect Awareness Project, with the goal of creating greater understanding and awareness of child neglect in Iowa.

Enantiomers' potential in psychopharmacology--a critical analysis with special emphasis on the antidepressant escitalopram

Stereochemistry is now influencing most areas of pharmacotherapy, with a growing awareness in the field of psychiatry and, more specifically, depression. This is due to the fact that the enantiomers of many chiral drugs may have distinct pharmacological, pharmacokinetic and/or pharmacogenetic profiles. Consequently, in some instances there may be an advantage in using a single enantiomer over the racemic form-thus providing a basis for the development of new therapeutic agents, as well as the potential to improve current treatments. This review highlights some of the potential advantages and disadvantages that using single enantiomers might offer. The principles are exemplified through reference to the stereoselective properties of several established chiral psychotropic drugs, including thioridazine, methadone, trimipramine, mianserin, mirtazapine, fluoxetine and citalopram. Emphasis is given to the treatment of depression and how the potential of one pure enantiomer-escitalopram, the S-enantiomer of the selective serotonin reuptake inhibitor citalopram-appears to be fulfilling its preclinical promise in the clinic.

Sign language in Landau-Kleffner syndrome.

This article reviews the history of sign language (SL) and the rationale for its use in children with profound auditory agnosia due to Landau-Kleffner syndrome (LKS), illustrated by studies of children and adults followed for many years and rare cases from the literature. The reasons that SL was successful and brought some children out of isolation while it could not be implemented in others are discussed. The nowadays earlier recognition and treatment of LKS and better awareness of the crucial need to maintain communication have certainly improved the outcome of affected children. Alternatives to oral language, even for less severe cases, are increasingly accepted. SL can be learned at different ages with a clear benefit, but the ambivalence of the patients and their families with the world and culture of the deaf may sometimes explain its refusal or limited acceptance. There are no data to support the fear that SL learning may delay or prevent oral language recovery in children with LKS. On the contrary, SL may even facilitate this recovery by stimulating functionally connected core language networks and by helping speech therapy and auditory training.

Review: Contact sport-related chronic traumatic encephalopathy in the elderly: clinical expression and structural substrates.

A. Costanza, K. Weber, S. Gandy, C. Bouras, P. R. Hof, P. Giannakopoulos and A. Canuto (2011) Neuropathology and Applied Neurobiology37, 570-584 Contact sport-related chronic traumatic encephalopathy in the elderly: clinical expression and structural substrates Professional boxers and other contact sport athletes are exposed to repetitive brain trauma that may affect motor functions, cognitive performance, emotional regulation and social awareness. The term of chronic traumatic encephalopathy (CTE) was recently introduced to regroup a wide spectrum of symptoms such as cerebellar, pyramidal and extrapyramidal syndromes, impairments in orientation, memory, language, attention, information processing and frontal executive functions, as well as personality changes and behavioural and psychiatric symptoms. Magnetic resonance imaging usually reveals hippocampal and vermis atrophy, a cavum septum pellucidum, signs of diffuse axonal injury, pituitary gland atrophy, dilated perivascular spaces and periventricular white matter disease. Given the partial overlapping of the clinical expression, epidemiology and pathogenesis of CTE and Alzheimer's disease (AD), as well as the close association between traumatic brain injuries (TBIs) and neurofibrillary tangle formation, a mixed pathology promoted by pathogenetic cascades resulting in either CTE or AD has been postulated. Molecular studies suggested that TBIs increase the neurotoxicity of the TAR DNA-binding protein 43 (TDP-43) that is a key pathological marker of ubiquitin-positive forms of frontotemporal dementia (FTLD-TDP) associated or not with motor neurone disease/amyotrophic lateral sclerosis (ALS). Similar patterns of immunoreactivity for TDP-43 in CTE, FTLD-TDP and ALS as well as epidemiological correlations support the presence of common pathogenetic mechanisms. The present review provides a critical update of the evolution of the concept of CTE with reference to its neuropathological definition together with an in-depth discussion of the differential diagnosis between this entity, AD and frontotemporal dementia.

Experience and endocrine stress responses in neonatal and pediatric critical care nurses and physicians.

OBJECTIVE: Critical care is a working environment with frequent exposure to stressful events. High levels of psychological stress have been associated with increased prevalence of burnout. Psychological distress acts as a potent trigger of cortisol secretions. We attempted to objectify endocrine stress reactivity. DESIGN: Observational cohort study during two 12-day periods in successive years. SETTING: A tertiary multidisciplinary neonatal and pediatric intensive care unit (33 beds). SUBJECTS: One hundred and twelve nurses and 27 physicians (94% accrual rate). INTERVENTIONS AND MEASUREMENTS: Cortisol determined from salivary samples collected every 2 hrs and after stressful events. Participants recorded the subjective perception of stress with every sample. Endocrine reactions were defined as transient surges in cortisol of >50% and 2.5 nmol/L over the baseline. MAIN RESULTS: During 7,145 working hours, we observed 474 (12.5%) endocrine reactions from 3,781 samples. The mean cortisol increase amounted to 10.6 nmol/L (219%). The mean occurrence rate of endocrine reactions per subject and sample was 0.159 (range, 0-0.43). Although the mean raw cortisol levels were lower in experienced team members (>3 yrs of intensive care vs. <3 yrs, 4.1 vs. 4.95 nmol/L, p < .001), professional experience failed to attenuate the frequency and magnitude of endocrine reactions, except for the subgroup of nurses and physicians with >8 yrs of intensive care experience. A high proportion (71.3%) of endocrine reactions occurred without conscious perception of stress. Unawareness of stress was higher in intensive care nurses (75.1%) than in intermediate care nurses (51.8%, p < .01). CONCLUSIONS: Stress-related cortisol surges occur frequently in neonatal and pediatric critical care staff. Cortisol increases are independent of subjective stress perception. Professional experience does not abate the endocrine stress reactivity.

Management of severe blunt hepatic injury in the era of computed tomography and transarterial embolization: A systematic review and critical appraisal of the literature.

BACKGROUND: During the last decade, the management of blunt hepatic injury has considerably changed. Three options are available as follows: nonoperative management (NOM), transarterial embolization (TAE), and surgery. We aimed to evaluate in a systematic review the current practice and outcomes in the management of Grade III to V blunt hepatic injury. METHOD: The MEDLINE database was searched using PubMed to identify English-language citations published after 2000 using the key words blunt, hepatic injury, severe, and grade III to V in different combinations. Liver injury was graded according to the American Association for the Surgery of Trauma classification on computed tomography (CT). Primary outcome analyzed was success rate in intention to treat. Critical appraisal of the literature was performed using the validated National Institute for Health and Care Excellence "Quality Assessment for Case Series" system. RESULTS: Twelve articles were selected for critical appraisal (n = 4,946 patients). The median quality score of articles was 4 of 8 (range, 2-6). Overall, the median Injury Severity Score (ISS) at admission was 26 (range, 0.6-75). A median of 66% (range, 0-100%) of patients was managed with NOM, with a success rate of 94% (range, 86-100%). TAE was used in only 3% of cases (range, 0-72%) owing to contrast extravasation on CT with a success rate of 93% (range, 81-100%); however, 9% to 30% of patients required a laparotomy. Thirty-one percent (range, 17-100%) of patients were managed with surgery owing to hemodynamic instability in most cases, with 12% to 28% requiring secondary TAE to control recurrent hepatic bleeding. Mortality was 5% (range, 0-8%) after NOM and 51% (range, 30-68%) after surgery. CONCLUSION: NOM of Grade III to V blunt hepatic injury is the first treatment option to manage hemodynamically stable patients. TAE and surgery are considered in a highly selective group of patients with contrast extravasation on CT or shock at admission, respectively. Additional standardization of the reports is necessary to allow accurate comparisons of the various management strategies. LEVEL OF EVIDENCE: Systematic review, level IV.

More than Words? An Analysis on the Language and Structure of General Election Manifestos of the British Labour Party 1983-2005

The topic of this study is the language of the educational policies of the British Labour party in the General Election manifestos between the years 1983-2005. The twenty-year period studied has been a period of significant changes in world politics, and in British politics, especially for the Labour party. The emergence educational policy as a vote-winner of the manifestos of the nineties has been noteworthy. The aim of the thesis is two-fold: to look at the structure of the political manifesto as an example of genre writing and to analyze the content utilizing the approach of critical discourse analysis. Furthermore, the aim of this study is not to pinpoint policy positions but to look at what is the image that the Labour Party creates of itself through these manifestos. The analysis of the content is done by a method of close-reading. Based on the findings, the methodology for the analysis of the content was created. This study utilized methodological triangulation which means that the material is analyzed from several methodological aspects. The aspects used in this study are ones of lexical features (collocation, coordination, euphemisms, metaphors and naming), grammatical features (thematic roles, tense, aspect, voice and modal auxiliaries) and rhetoric (Burke, Toulmin and Perelman). From the analysis of the content a generic description is built. By looking at the lexical, grammatical and rhetorical features a clear change in language of the Labour Party can be detected. This change is foreshadowed already in the 1992 manifesto but culminates in the 1997 manifesto which would lead Labour to a landslide victory in the General Election. During this twenty-year period Labour has moved away from the old commitments and into the new sphere of “something for everybody”. The pervasiveness of promotional language and market inspired vocabulary into the sphere of manifesto writing is clear. The use of the metaphors seemed to be the tool for the creation of the image of the party represented through the manifestos. A limited generic description can be constructed from the findings based on the content and structure of the manifestos: especially more generic findings such as the use of the exclusive we, the lack of certain anatomical parts of argument structure, the use of the future tense and the present progressive aspect can shed light to the description of the genre of manifesto writing. While this study is only the beginning, it proves that the combination of looking at the lexical, grammatical and rhetorical features in the study of manifestos is a promising one.
