Luminosity functions to statistically constrain galaxy evolution
No full textopenCi si è proposti di studiare l’origine delle funzioni di luminosità, con un focus particolare sulla funzione di Schechter. Lo studio è partito proprio dalla Spectral Energy Distribution (SED), dalla quale si ricavano molte informazioni fisiche della galassia. Successivamente si è proposto uno scorcio sulla statistica delle galassie e così la spiegazione sulle funzioni di luminosità. Son stati definiti inoltre altri metodi, diversi dalla Schechter o dallo stimatore 1/Vmax, per stimare le funzioni di luminosità, come per esempio la statistica Bayesiana. Infine si è conclusa la tesi con vari esempi di utilizzo e di studio delle funzioni di luminosità per diverse galassie o ammassi di galassie
Fall 2016 Supplement to Brauneis & Schechter, Copyright: A Contemporary Approach
No full textThis cumulative supplement contains additional materials for Brauneis and Schechter, Copyright: A Contemporary Approach (1st ed. 2012) that make it current through July 2016. Special features include a hyperlinked table of references to 19 recent cases decided since July 2015, which may be helpful in getting an overview of developments over this past year; a hyperlinked table of contents to all inserts; and a chapter-by-chapter guide to using the supplement, intended for professors who are creating or updating syllabi. The supplement contains nine principal cases with notes, as well as dozens of other updates
Comb-e-Chem: an e-science research project
No full textThe background to the Comb-e-Chem e-Science pilot project funded under the UK-Science Programme is presented and the areas being addresses within chemistry and more specifically combinatorial chemistry are discussed. The ways in which the ideas underlying the application of computer technology can improve the production, analysis and dissemination of chemical information and knowledge in a collaborative environment are discussed
Helmick + Schechter : Exquisite Corpse
No full textCapasso describes Helmick and Schechter’s public art installation, which consists of 19 equidistant stained-glass panels that represent anatomical cross-sections of the human body based on data from the Visible Human Project® (National Library of Medicine). Installed in the Minnesota Bureau of Criminal Apprehension, the work also incorporates imagery linked to forensic investigation. Includes technical details on the work and a description of the panels
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Gender confirmation surgery : guiding principles
No full textBackground At this time, no formal training or educational programs exist for surgeons or surgery residents interested in performing gender confirmation surgeries. Aim To propose guiding principles designed to aid with the development of formal surgical training programs focused on gender confirmation surgery. Methods We use expert opinion to provide a “first of its kind” framework for training surgeons to care for transgender and gender nonconforming individuals. Outcomes We describe a multidisciplinary treatment model that describes an educational philosophy and the institution of quality parameters. Results This article represents the first step in the development of a structured educational program for surgical training in gender confirmation procedures. Clinical Implications The World Professional Association for Transgender Health Board of Directors unanimously approved this article as the framework for surgical training. Strengths and Limitations This article builds a framework for surgical training. It is designed to provide concepts that will likely be modified over time and based on additional data and evidence gathered through outcome measurements. Conclusion We present an initial step in the formation of educational and technical guidelines for training surgeons in gender confirmation procedures. Schechter LS, D'Arpa S, Cohen MN, et al.
