Il «Faust» di Pessoa: una tragedia del soggetto
No full textLa molteplicità degli interessi di Fernando Pessoa investiva anche il campo teatrale, come è dimostrato non solo dal suo “dramma statico” Il marinaio, pubblicato nel 1915, ma anche dal suo Faust, il quale, al di là dell’essere incompiuto e frammentario, si presenta come un’opera teatrale di certo sui generis, più prossima alla lirica che alla drammaturgia. Potremmo definirla un’opera peculiarmente pessoana, tenendo conto anche del suo sottotitolo, quello di «tragedia soggettiva», ovvero, una tragedia del soggetto, quindi, dello stesso Fernando Pessoa, la cui tragedia soggettiva è la vera protagonista della sua propria condizione esistenziale

Alcoholism recovery and treatment needs of women
No full textPlan BAmong American women, alcohol is the single leading drug of abuse, yet research in addiction has concentrated on male subjects. Most models of treatment were developed to meet the needs of male patients. Contemporary research indicates that clear differences in substance abuse effects exist between men and women. This study identified specific issues or themes that could help augment recovery for women who are in treatment for alcoholism. Structured interviews were conducted with seven adult women, 21 years or older who are in recovery from alcohol dependence and who regularly attend AA meetings. The study addressed several issues pertaining to women’s alcoholism that formed themes relating to factors that could help women obtain treatment earlier and elements of treatment programs that could be more responsive to female clients and improve their aftercare services. The respondents were asked ten open-ended questions concerning issues that were important in their recovery from alcoholism but were not adequately addressed while in treatment and aftercare. It was found that the two youngest women sought treatment earlier than most of the older women, and that other women often were the impetus for many of the participants seeking treatment. The participants’ answers indicated that if women’s emotional concerns were addressed more in treatment, they likely would have benefited more from treatment. Relationship health was an important topic for women in this study. It was also found that, in general, the women in this study were not satisfied with their counselors in treatment or in aftercare. Information gathered through this study may be helpful to identify the specific recovery and treatment needs of women with alcoholism
Open Access to Peer-Reviewed Research through Author/Institution Self-Archiving: Maximizing Research Impact by Maximizing Online Access
No full textAll refereed journals will soon be available online; most of them already are. This means that anyone will be able to access them from any networked desk-top. The literature will all be interconnected by citation, author, and keyword/subject links, allowing for unheard-of power and ease of access and navigability. Successive drafts of pre-refereeing preprints will be linked to the official refereed draft, as well as to any subsequent corrections, revisions, updates, comments, responses, and underlying empirical databases, all enhancing the self-correctiveness, interactivity and productivity of scholarly and scientific research and communication in remarkable new ways. New scientometric indicators of digital impact are also emerging <http://opcit.eprints.org> to chart the online course of knowledge. But there is still one last frontier to cross before science reaches the optimal and the inevitable: Just as there is no longer any need for research or researchers to be constrained by the access-blocking restrictions of paper distribution, there is no longer any need to be constrained by the impact-blocking financial fire-walls of Subscription/Site-License/Pay-Per-View (S/L/P) tolls for this give-away literature. Its author/researchers have always donated their research reports for free (and its referee/researchers have refereed for free), with the sole goal of maximizing their impact on subsequent research (by accessing the eyes and minds of fellow-researchers, present and future) and hence on society. Generic (OAi-compliant) software is now available free so that institutions can immediately create Eprint Archives in which their authors can self-archive all their refereed papers for free for all forever <http://www.eprints.org/>. These interoperable Open Archives <http://www.openarchives.org> will then be harvested into global, jointly searchable "virtual archives" (e.g., <http://arc.cs.odu.edu/>). "Scholarly Skywriting" in this PostGutenberg Galaxy will be dramatically (and measurably) more interactive and productive, spawning its own new digital metrics of productivity and impact, allowing for an online "embryology of knowledge.
Author attribution using profile classifiers
No full textA atribuição autoral (AA) busca identificar um autor de texto a partir de um conjunto de autores conhecidos. Autores deixam rastros em seus textos e é possível identificar características sociolinguísticas baseadas no estilos de escrita refletidos no texto destes autores. A atribuição autoral está cada vez mais demonstrando importância para diversas atividades sociais, em especial para a análise forense. Os trabalhos envolvendo AA demonstram resultados modestos e motivam a exploração de diferentes técnicas para melhorar a acurácia dos modelos atuais. A partir desses pontos, o presente trabalho apresenta uma proposta de pesquisa em nível de mestrado no campo de processamento de língua natural (PLN), com ênfase em AA, com o objetivo geral de melhorar o desempenho de classificadores de atribuição autoral utilizando técnicas de caracterização autoral (CA)Author attribution (AA) seeks to identify a text author from a set of known authors. Authors leave traces in their texts and it is possible to identify sociolinguistic characteristics based on the writing styles reflected in the text of these authors. Author attribution is increasingly showing importance for various social activities, especially forensic analysis. Studies involving AA show modest results and motivate the exploration of different techniques to improve the accuracy of current models. From these perspective, this project presents a master\'s level research proposal in the field of natural language processing (NLP), with an emphasis in AA, with the general objective of improving the performance of AA classifiers using author profiling technique

Phys. 63, 2861 (1975).Author Institution:Niobium nitride emission systems have been found at 5l37{\AA}, 5582{\AA}, 5740{\AA}, 5840{\AA}, 5860{\AA}, in addition to the already systems with subbands at 5930{\AA}, 6043{\AA}, and 6192{\AA}. Most of These systems show marked nuclear hyperfine structure of the rotational lines add this has been of assistance in the analysis of all of the systems. Systems of triplet-triplet, singlet-singlet and singlet-triplet are all present and the hyperfine structure also allows assignment of the ground and excited state electron configuration to be made with some confidence
THE 4550 {\AA} BAND SYSTEM OF GLYOXAL
No full textAuthor Institution: Division of Pure Physics, National Research Council“Approximately 45 bands of glyoxal in the region 4000-4660 {\AA} have been photographed in absorption using a 30 ft. Ebert spectrograph with a resolving power of and a dispersion of 1.3 {\AA}/cm. The (0-0) baud near 4550 {\AA}, which WAS studied at a temperature of C, shows fairly well-resolved J- and K- structure characteristic of a perpendicular hand of a near symmetric top molecule. The rotational and vibrational analysis of the speetrum will be discussed.

A219, 89 (1953).Author Institution: Space Physics Laboratory, Aerospace Corporation“The absorption of ultraviolet radiation by sodium vapor, and the associated ionization, has been investigated from 1040{\AA} to 3500{\AA} using a two-metre McPherson normal incidence spectrometer and an absorption chamfer of the type described by Ditchburn and The atomic cross section at the series limit (2412 {\AA}) was found to be , in good agreement with the previous result obtained by Ditchburn, Jutsum and The atomic cross section decreases to a minimum at 1900{\AA} and then increases again towards shorter wavelengths. Continuous molecular absorption was observed from 3500{\AA} to 1700{\AA} and ion chamber measurement indicate that this absorption is due to an ionization continuum. Ion current peaks were also seen between 2413{\AA} and 3500{\AA} at wavelengths corresponding to the series absorption lines of the sodium atom. Curves will be presented showing the variation with wavelength of both the atomic cross section and the relative molecular cross section.

No full textAuthor Institution: Department of Chemistry, Columbia University; Laboratoire de Photophysique, Moleculaire C.N.R.S. University of Paris-Sud; Department of Chemistry, Columbia UniversityFrom an analysts of the rotationally resolved fluorescence of excited by a narrow band (0.03 {\AA}) tunable dye laser, quantum numbers have been assigned to 80 transitions in the 6l25 {\AA} region. Three band origins are observed in a 20 {\AA} interval, two of which have also been seen in a nozzle beam seeded with A rotational analysis of the 6125 {\AA} and 6127 {\AA} bands is reported, while the small number of transitions assigned to the 6117 {\AA} band presently prevents analysis. Under collision-free conditions ( mTorr) the ``average” radiative lifetimes of the 6117 {\AA} band and the 6125 {\AA} band are sec and sec, respectively. Comments are made concerning the vibrational overlap in this region
