Uma melhoria no processo ágil da COTIC-PROEG da UFPA para atendimento do processo de desenvolvimento de requisitos do MR-MPS-SW
No full textNowadays, many companies seek to improve their software process development, using quality models as its foundation. In this context, the Brazilian Software Process Improvement (MPS.BR), as well as the Software MPS Model (MR-MPS-SW), were created. Frequently, organizations face difficulties on developing software requirements for a software product, which is a crucial factor to guarantee the creation of high-quality software. This work proposes an improvement on the agile development process of COTIC-PROEG, using the Requirements Development (DRE) process, from the MR-MPS-SW quality model, as its foundation. To do so, was made the modeling of the COTIC present process, which was used to make an evaluation based on the evidences of it attending the DRE expected results, found in the Software Implementation Guide of maturity level D of MR-MPS-SW, and then proposed a new development process, in a way that all expected results are fulfilled.Atualmente, muitas empresas buscam aprimorar seu processo de desenvolvimento de software utilizando modelos de qualidade como base.

Frequentemente, as organizações enfrentam dificuldades na etapa de desenvolvimento dos requisitos do produto de software, fator crucial para a garantia da criação de software com qualidade. Esse trabalho propõe uma melhoria do processo ágil de desenvolvimento da COTIC-PROEG, utilizando como base o processo de Desenvolvimento de Requisitos (DRE) do modelo de qualidade MR-MPS-SW, que tem como objetivo o estabelecimento de requisitos que atendam as expectativas, necessidades e restrições do cliente. Para tal, foi realizada a modelagem do processo atual de desenvolvimento da COTIC, sob o qual foi realizada uma avaliação com base em evidências de atendimento aos resultados esperados do DRE, presentes no Guia de Implementação de Software do nível de maturidade D do MR-MPS-SW, e então proposto um novo processo de desenvolvimento, de forma que todos os resultados esperados sejam completamente atendidos
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
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
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
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

The R&D Tax Incentives
No full textThis article sets out some background information and reflections of the author on the R&D tax incentive schemes included in the Common Corporate Tax Base (CCTB) Proposal. In particular the author analyzes the stimulus to private R&D through ad hoc tax incentives included in the CCTB Proposal and dives into the actual provisions included in the Proposal highlighting the most relevant issues connected with their design and interpretation. Moreover, the author explores the interaction between the CCTB Proposal and the granting by Member States of domestic R&D tax incentives
Unusually high energy barriers for internal conversion in a {Ru(bpy)} chromophore
No full textInternal conversion (IC) coupled to vibrational relaxation (VR) in molecular chromophores is a source of major energy losses in natural and artificial solar-to-chemical energy conversion schemes. The development of anti-Kasha chromophores, where dissipative IC channels are blocked, is a promising strategy to boost energy conversion efficiencies. In this contribution, we demonstrate the presence of an unusually high kinetic barrier for IC in [Ru(tpm)(bpy)(NCS)]+ (RuNCS), where tpm is tris(1-pyrazolyl)methane and bpy is 2,2'-bipyridine, by means of an arsenal of temperature-dependent spectroscopic methods including nanosecond and femtosecond transient absorption spectroscopies. These studies are complemented with theoretical investigations, that provide a detailed atomistic description of the dissipation process, including the electronic structures of the excited states involved. The observed IC is mainly a hole reconfiguration within the octahedral t2g set of the Ru ion, with contributions from a Ru to NCS charge transfer. Thus, in a Marcus picture, inner and outer reorganizations contribute to the observed barrier. The results presented here show that wavefunction symmetry within a molecular chromophore can be exploited to inhibit dissipative IC. Finally, guidelines for the design of anti-Kasha chromophores that prevent dissipation in energy conversion schemes, based on minimum energy conical intersection calculations, are provided.sponsorship: A.
