Flow-bed interactions analysis and application of automatic close range digital photogrammetric survey in a laboratory flume
2014
This paper reports on a laboratory study in which the automatic digital photogrammetric survey was applied to derive the high-resolution Digital Surface Model (DSM) of the bed topography, used for the flow-bed interactions analysis, in a large amplitude meandering laboratory flume. The analysis has been conducted with the aid of detailed data of three-dimensional flow field previously collected using the acoustic Doppler velocity profiler DOP2000. The applied surveying procedure has allowed the evaluation of the DSM with a resolution of ±0.5 mm. The detailed DSM has been compared with peculiar maps describing the flow velocity pattern (downstream and the crossstream flows) and the shear vel…
Influence of Distance from the Host on Parasitisation by
2019
The olive fruit fly, Bactrocera oleae, is considered the main olive pest worldwide, and has been the target of biological control programmes through the release of the braconid parasitoid Psyttalia concolor. Laboratory tests were performed to evaluate the influence of distance from the host on parasitisation, placing larvae of the substitute host Ceratitis capitata at seven distances (0, 0.5, 1, 1.5, 2, 2.5, 3 mm) and four different time periods (7, 15, 30, 60 min). Moreover, field collected olives of Ogliarola Barese cultivar infested by B. oleae were exposed to P. concolor females to confirm its ability to parasitise B. oleae in small olives. Psyttalia concolor oviposition was inhibited a…
Inappropriateness in laboratory medicine: an elephant in the room?
2017
Appropriateness of diagnostic testing can be conventionally described as prescription of the right test, using the right method, at the right time, to the right patient, with the right costs and for producing the right outcome. There is ongoing debate about the real burden of inappropriateness in laboratory diagnostics. The media coverage of this issue has also recently led to either over- or under-emphasizing the clinical, organizational and economic consequences. This is quite problematic, inasmuch as some reliable data are available in the current scientific literature, showing that inappropriateness of laboratory testing can be as high as 70%. This is especially evident for, though not …
Efficacy of three drugs for protecting against gentamicin-induced hair cell and hearing losses
2012
BACKGROUND AND PURPOSEExposure to an ototoxic level of an aminoglycoside can result in hearing loss. In this we study investigated the otoprotective efficacy of dexamethasone (DXM), melatonin (MLT) and tacrolimus (TCR) in gentamicin (GM)-treated animals and cultures.EXPERIMENTAL APPROACHWistar rats were divided into controls (treated with saline); exposed to GM only (GM); and three GM-exposed groups treated with either DXM, MLT or TCR. Auditory function and cochlear surface preparations were studied. In vitro studies of oxidative stress, pro-inflammatory cytokine mRNA levels, the MAPK pathway and caspase-3 activation were performed in organ of Corti explants from 3-day-old rats.KEY RESULTSD…
Initial support teachers training through Mcdrury & Alterio’s storytelling model storytelling methodology. A research in the laboratories of the spec…
2019
Creating digital stories provides with important opportunities to practice and master a number of specific 21st-century skills, content, and technology standards. Storytelling has been extensively used in children’s education as a valuable and creative tool, however, its use in the higher education process has been less common and this paper proposes that storytelling can be used as an effective reflective tool in higher education. Digital storytelling is essentially the application of technology to this age-old experience of sharing personal narratives and seeking to teach and learn from them. What is different, and what makes these digital stories so potentially powerful, is the availabil…
Labor-Market Returns to Higher Vocational Schooling
2018
This paper examines the labor-market returns to a new form of postsecondary vocational education, vocational master's degrees. We use individual fixed effects models on the matched sample of students and non-students from Finland to capture any time-invariant differences across individuals. Attendance in vocational master's programs leads to higher earnings of eight percent five years after entry even if selection on unobservables is twice as strong as selection on observables. Earnings gains are similar by gender and age, but they are marginally higher for health than for business or technology and trades. nonPeerReviewed
Groupware architecture for requirements processes in new product development
1999
An organization's ability to create successful products depends on how extensively it collects, analyzes and utilizes requirements information in its product development. Recent advances in groupware technologies allow such information to be shared more effectively in distributed organizations; thus, these technologies hold considerable potential as means of shortening the cycle time and improving the quality of requirements processes. This paper addresses issues in the design and implementation of groupware-supported requirements processes by drawing on experiences from large-scale industrial development projects within Nokia. The primary contribution of the paper is the conceptual design …
SOUTH AMERICAN COLLABORATION IN SCIENTIFIC PUBLICATIONS ON LEISHMANIASIS: BIBLIOMETRIC ANALYSIS IN SCOPUS (2000-2011)
2014
Objetivos: Evaluar la producción y la red de colaboración de investigación sobre leishmaniasis en Sudamérica. Métodos: Se realizó un estudio bibliométrico usando la base de datos SCOPUS. La unidad de análisis fueron los artículos originales de investigación publicados desde el año 2000 hasta 2011, realizados sobre leishmaniasis y que incluyeron al menos un autor sudamericano. Se obtuvieron para cada artículo: nombre de la revista, idioma, año de publicación, número de autores, instituciones, países y otras variables. Resultados: 3174 artículos fueron publicados, 2.272 de ellos eran artículos originales. Se identificaron 1.160 firmas institucionales diferentes, 58 países y 398 revistas cient…
Do Software Firms Collaborate or Compete? A Model of Coopetition in Community-initiated OSS Projects
2019
[Background] An increasing number of commercial firms are participating in Open Source Software (OSS) projects to reduce their development cost and increase technical innovativeness. When collaborating with other firms whose sought values are conflicts of interests, firms may behave uncooperatively leading to harmful impacts on the common goal. [Aim] This study explores how software firms both collaborate and compete in OSS projects. [Method] We adopted a mixed research method on three OSS projects. [Result] We found that commercial firms participating in community-initiated OSS projects collaborate in various ways across the organizational boundaries. While most of firms contribute little,…
