A Small Settings Case Study using TSPi in a Software Project

This article introduces a small setting case study about the benefits of using TSPi in a software project. An adapted process from the current process based on the TSPi was defined. The pilot project had schedule and budget constraints. The process began by gathering historical data from previous projects in order to get a measurement repository. The project was launched with the following goals: increase the productivity, reduce the test time and improve the product quality. Finally, the results were analysed and the goals were verified.

Agile Case Study Evaluation In Middle Size Project

In the last few years Agile methodologies appeared as a reaction to traditional ways of developing software and acknowledge the need for an alternative to documentation driven, heavyweight software development processes. This paper shortly presents a combination between Rational Uni ed Process and an agile approach for software development of e-business applications. The resulting approach is described stressing on the strong aspects of both combined methodologies. The article provides a case study of the proposed methodology which was developed and executed in a successful e-project in the area of the embedded systems.

Facile synthesis and proposed mechanism of α,ω‐oxetanyl-telechelic poly(3-nitratomethyl-3-methyl oxetane) by an SN2(i) nitrato displacement method in basic media

The synthesis of a novel heterocyclic–telechelic polymer, α,ω-oxetanyl-telechelic poly(3-nitratomethyl-3-methyl oxetane), is described. Infrared spectroscopy (IR), gel permeation chromatography (GPC), and nuclear magnetic resonance (NMR) spectroscopy have been used to confirm the successful synthesis, demonstrating the presence of the telechelic-oxetanyl moieties. Synthesis of the terminal functionalities has been achieved via displacement of nitrato groups, in a manner similar to that employed with other leaving groups such as azido, bromo, and nitro, initiated by nucleophiles. In the present case, displacement occurs on the ends of a nitrato-functionalized polymer driven by the formation of sodium nitrate, which is supported by the polar aprotic solvent N,N-dimethyl formamide. The formation of an alkoxide at the polymer chain ends is favored and allows internal back-biting to the nearest carbon bearing the nitrato group, intrinsically in an SN2(i) reaction, leading to α,ω-oxetanyl functionalization. The telechelic-oxetanyl moieties have the potential to be cross-linked by chemical (e.g., acidic) or radiative (e.g., ultraviolet) curing methods without the use of high temperatures, usually below 100°C. This type of material was designed for future use as a contraband simulant, whereby it would form the predominant constituent of elastomeric composites comprising rubbery polymer with small quantities of solids, typically crystals of contraband substances, such as explosives or narcotics. This method also provides an alternative approach to ring closure and synthesis of heterocycles.

Similarities and Differences in Polish and Hungarian History

In my lecture I would like to give a general introduction to a comparative approach of Polish and Hungarian history. I am convinced it could be not only an interesting, but a relevant issue as well. This approach could be touching emotionally for average Hungarian and Polish people because both nations strongly felt last centuries that they had common historical fate in East Central Europe. There is evidence which prove that Polish-Hungarian friendship is not only a modern phenomenon, but it is originated from the historical past. Historical memory calls the attention that Polish-Hungarian friendship was rooted already in the early modern history, and it was not constructed by historians, but a special relationship between the two nations was a widespread and accepted concept for the wider public in Hungary. I can cite the well-known proverb which represents it: „Pole and Hungarian – two good friends, joint fight and drinking are their ends.” In this lecture I don’t want to give a complete list of differences and similarities, but to call the attention to some interesting aspects of two nations’ common historical fate.

Students' Perceptions and Opinions of Unscientific Bias in Evolutionary Curriculum

This is a qualitative study with eighth-grade students assessing their views of bias within the evolution chapters of two Florida state-adopted texts. The students determined that a significant degree of bias exists. The texts fail to develop the scientific "habits-of-mind" as stated in the school district's "science as inquiry" competencies.

Role of galaxy mergers in cosmic star formation history

We present a morphology study of intermediate-redshift (0.2 < z < 1.2) luminous infrared galaxies (LIRGs) and general field galaxies in the GOODS fields using a revised asymmetry measurement method optimized for deep fields. By taking careful account of the importance of the underlying sky-background structures, our new method does not suffer from systematic bias and offers small uncertainties. By redshifting local LIRGs and low-redshift GOODS galaxies to different higher redshifts, we have found that the redshift dependence of the galaxy asymmetry due to surface-brightness dimming is a function of the asymmetry itself, with larger corrections for more asymmetric objects. By applying redshift-, infrared (IR)-luminosity- and optical-brightness-dependent asymmetry corrections, we have found that intermediate-redshift LIRGs generally show highly asymmetric morphologies, with implied merger fractions ~50% up to z = 1.2, although they are slightly more symmetric than local LIRGs. For general field galaxies, we find an almost constant relatively high merger fraction (20%-30%). The B-band luminosity functions (LFs) of galaxy mergers are derived at different redshifts up to z = 1.2 and confirm the weak evolution of the merger fraction after breaking the luminosity-density degeneracy. The IR LFs of galaxy mergers are also derived, indicating a larger merger fraction at higher IR luminosity. The integral of the merger IR LFs indicates a dramatic evolution of the merger-induced IR energy density [(1 + z)^~(5-6)], and that galaxy mergers start to dominate the cosmic IR energy density at z greater than or ~ 1.

The Antibiotic Resistance and Prescribing in European Children Project: A Neonatal and Pediatric Antimicrobial Web-based Point Prevalence Survey in 73 Hospitals Worldwide

BACKGROUND: The neonatal and pediatric antimicrobial point prevalence survey (PPS) of the Antibiotic Resistance and Prescribing in European Children project (http://www.arpecproject.eu/) aims to standardize a method for surveillance of antimicrobial use in children and neonates admitted to the hospital within Europe. This article describes the audit criteria used and reports overall country-specific proportions of antimicrobial use. An analytical review presents methodologies on antimicrobial use.

METHODS: A 1-day PPS on antimicrobial use in hospitalized children was organized in September 2011, using a previously validated and standardized method. The survey included all inpatient pediatric and neonatal beds and identified all children receiving an antimicrobial treatment on the day of survey. Mandatory data were age, gender, (birth) weight, underlying diagnosis, antimicrobial agent, dose and indication for treatment. Data were entered through a web-based system for data-entry and reporting, based on the WebPPS program developed for the European Surveillance of Antimicrobial Consumption project.

RESULTS: There were 2760 and 1565 pediatric versus 1154 and 589 neonatal inpatients reported among 50 European (n = 14 countries) and 23 non-European hospitals (n = 9 countries), respectively. Overall, antibiotic pediatric and neonatal use was significantly higher in non-European (43.8%; 95% confidence interval [CI]: 41.3-46.3% and 39.4%; 95% CI: 35.5-43.4%) compared with that in European hospitals (35.4; 95% CI: 33.6-37.2% and 21.8%; 95% CI: 19.4-24.2%). Proportions of antibiotic use were highest in hematology/oncology wards (61.3%; 95% CI: 56.2-66.4%) and pediatric intensive care units (55.8%; 95% CI: 50.3-61.3%).

CONCLUSIONS: An Antibiotic Resistance and Prescribing in European Children standardized web-based method for a 1-day PPS was successfully developed and conducted in 73 hospitals worldwide. It offers a simple, feasible and sustainable way of data collection that can be used globally.

A recipe for scavenging in vertebrates - the natural history of a behaviour

Despite its prevalence, the importance of scavenging to carnivores is difficult to ascertain in modern day forms and impossible to study directly in extinct species. Yet, there are certain intrinsic and environmental features of a species that push it towards a scavenging lifestyle. These can be thought of as some of the principal parameters in optimal foraging theory namely, encounter rate and handling time. We use these components to highlight the morphologies and environments that would have been conducive to scavenging over geological time by focusing on the dominant vertebrate groups of the land, sea and air. The result is a synthesis on the natural history of scavenging. The features that make up our qualitative scale of scavenging can be applied to any given species and allow us to judge the likely importance of this foraging behaviour.

Adolescent depression in schools: + Contigo Project

epidemiological data. It involves a high degree of mortality, namely by suicide, which is the third leading cause of death in the 15-24 age group. Objectives: To assess the presence and severity of depressive symptoms in a non-clinical population of adolescents. Methodology: This is a quantitative, descriptive and cross-sectional study, using the Portuguese version of the Beck Depression Inventory (BDI-II). The sample was composed of 741 adolescents. Results: The results show that 31.2% of the adolescents have depression and, of these, 17.7% have moderate to severe depressive symptoms. Girls have higher levels of depression (p=.00). The total mean score in the BDI-II was 12. Conclusion: Given the adolescents' high vulnerability to depression and suicide, it is essential to implement prevention programs in schools to promote the early detection of depression and suicidal behaviors, and the referral to mental health services.

Sicily in Transition Research Project. Investigations at Castronovo di Sicilia. Results and Prospects, 2015

Il progetto Sicily in Transition è nato dalla collaborazione delle Università di York e di Roma Tor Vergata, con il pieno ap-poggio della Soprintendenza ai BB. CC. AA di Palermo. La finalità della nostra ricerca è quella di analizzare, attraverso il registro archeologico, in quale modo i mutamenti di regime politico hanno influenzato organizzazione, composizione e stili di vita delle popolazioni soggette. L’arco di tempo considerato va dal VI al XIII secolo, periodo nel quale la Sicilia ha visto diverse dominazioni: quella bizantina, islamica, normanna e sveva. Sicily in Transition prevede di analizzare con metodi in parte nuovi, in parte più tradizionali, sia insiemi di reperti (ecofatti e manufatti) prodotti da precedenti scavi, sia di acquisire dati attraverso nuove indagini. In particolare gli scriventi hanno scelto di indagare un’area molto promettente della Sicilia centrale: il territorio di Castronovo di Sicilia. Qui, in due campagne di ricerca durate ciascuna quattro settimane, sono state realizzate indagini magnetometriche, ricognizioni di superficie, di archeologia dell’architettura e sondaggi stratigrafici. La finalità era quella di valutare il potenziale archeologico dei principali siti storici del territorio. I primi risultati sono promettenti in relazione alla varietà tipologica e cronologica dei diversi insediamenti identificati: una fortezza dei secoli VII-IX sul Monte Kassar; un fortilizio con fasi del pieno medioevo e dell’età moderna sul Colle San Vitale; un ampio villaggio non difeso con fasi dall’età tardoantica al medioevo, incluse importanti testimonianze di età islamica, nell’area del Casale San Pietro. Le indagini preliminari hanno quindi confermato le ampie potenzialità informative dell’intero territorio di Castronovo rispetto ai temi della nostra ricerca e stanno quindi consentendo di programmare gli interventi futuri.
