Abstrakti luokka vai rajapinta uudelleenkäytettävyyden näkökulmasta
2013
Tämä kandidaatintutkielma on kirjallisuuskatsaus. Tutkielman tutkimuskysymys on, tarjoaako abstrakti luokka paremman uudelleenkäytettävyyden kuin rajapinta. Tutkielmassa noudatettiin EBSE-menetelmää. Tutkielmassa havaitaan, että kuluja, joita syntyy ohjelmistokehityksessä voidaan vähentää uudelleenkäyttämällä ohjelmakoodia. Tutkielmassa saatiin tulokseksi, että uudelleenkäytettävyyttä edistävät kapselointi, matala kytkösaste, korkea koheesio ja perintä. Uudelleenkäytettävyyttä haittaa heikko ymmärrettävyys. Perintä ja koostaminen ovat keinoja, joilla koodia voidaan uudelleenkäyttää. Tutkielmassa havaittiin, että abstraktin luokan ja rajapinnan keskeisin ero on se, että abstraktilla luokalla…
S’imprégner de la démarche réflexive pour favoriser la transformation des pratiques pédagogiques dans l’enseignement supérieur
2022
Il existe actuellement une tendance générale de l’enseignement supérieur vers les pratiques réflexives et la professionnalisation, dont le Portfolio d’Apprentissage et d'Évaluation fait partie (Petit et al., 2018). La réforme des IUTs de 2021 a imposé, entre autres, à tous les IUTs de France de s’engager dans une démarche de déploiement de la méthode portfolio. Son pilotage implique l’appropriation de la démarche et la collaboration de différents acteurs et services pour accompagner les étudiants et les enseignants à transformer leurs pratiques respectives (Lalle et Bonnafous, 2019). Sur la base du modèle du praticien réflexif (Schön, 1983; Slepcevic-Zach et Stock, 2018) et en mobilisant l’…

Alliance portfolio diversity, organizational slack, and firm performance
2013
In this paper we analyze whether and how the availability of internal resources in the form of slack influences a firm ability to deal with partner diversity in its alliance portfolio. Alliances with diverse partners provide access to a broader pool of complementary resources, but they also entail significant coordination costs. In this context, we argue that slack acts as a doubleedged sword that can either facilitate or hinder the management of interdependencies among different alliance projects. Accordingly, we further argue that the net impact of slack will depend on the firm’s experience in dealing with the challenges posed by portfolio diversity. Empirical analysis on a sample of firm…
Optimal portfolio allocation with real assets : a Finnish perspective
2017
Alternative market assets, i.e. those which are not part of the ''traditional'' financial assets, have become increasingly popular globally during the last decade. The purpose of this study is to examine the potential benefits of including real investment assets, specifically timberland and real estate holdings, for a investor investing to either domestic or international markets. Specifically the questions to be asked are: Do Finnish real investment assets offer diversification benefits in respect of increased risk-adjusted returns? What are the optimal asset allocations? The analyzed time-series for alternative investments represent quarterly total returns of average Finnish timberland an…
Structural Insight into CVB3-VLP Non-Adjuvanted Vaccine
2020
Coxsackievirus B (CVB) enteroviruses are common pathogens that can cause acute and chronic myocarditis, dilated cardiomyopathy, aseptic meningitis, and they are hypothesized to be a causal factor in type 1 diabetes. The licensed enterovirus vaccines and those currently in clinical development are traditional inactivated or live attenuated vaccines. Even though these vaccines work well in the prevention of enterovirus diseases, new vaccine technologies, like virus-like particles (VLPs), can offer important advantages in the manufacturing and epitope engineering. We have previously produced VLPs for CVB3 and CVB1 in insect cells. Here, we describe the production of CVB3-VLPs with enhanced pro…
Portafolio digital: un nuevo formato de aprendizaje
2014
El presente documento recoge un estudio exploratorio sobre el uso del E-portafolio como herramienta de innovacion en la docencia universitaria de una asignatura. La investigacion se basa en un estudio de naturaleza descriptiva a traves de la tecnica de la encuesta (cuestionario). Los resultados muestran que se trata de una herramienta de aprendizaje valorada positivamente y que plantean una serie de aspectos positivos valorados altamente como la accesibilidad al aprendizaje cooperativo o el ahorro economico y medio ambiental que supone prescindir de la impresion en papel. El E-portafolio es un instrumento que contribuye al proceso de ensenanza-aprendizaje, que ayuda a que el alumnado sea co…
Procesos de expolio y reutilización de la arquitectura pública romana en el territorio valenciano
2018
Se efectúa un análisis de los procesos de expolio y transformación de grandes conjuntos monumentales y edificios singulares, fundamentalmente para espectáculos, en las ciudades romanas ubicadas en el territorio que en la actualidad integra el País Valenciano. El foro, por su condición de locus celeberrimus en el paisaje urbano romano, constituye el mejor indicador del ritmo e intensidad con que esos espacios privilegiados, en unos casos, sucumbieron en un proceso de abandono generalizado, como en Lucentum (el Tossal de Manises, Alicante), mientras que en ciudades habitadas hasta nuestros días, como es Valencia, se asistió a una imparable transformación de su imagen hasta no quedar huella al…
Changes in surface stress, morphology and chemical composition of silica and silicon nitride surfaces during the etching by gaseous HF acid
2007
International audience; HF acid attack of SiO2 and Si3N4 substrates is analyzed to improve the sensitivity of a sensor based on inicrocantilever. Ex situ analysis of the etching using XPS, SIMS and AFM show significant changes in the anisotropy and the rate of the etching of the oxides on SiO2 and Si3N4 surface. Those differences influence the kinetic evolution of the plastic bending deflection of the cantilever coated with SiO2 and Si3N4 layer, respectively. The linear dependence between the HF concentration and the Si3N4 cantilever bending corresponds to a deep attack of the layer whereas the nonlinear behavior observed for SiO2 layer can be explained by a combination of deep and lateral …
Biodegradazione di miscele di gasolio in suoli contaminati
2008
Il biorisanamento mediante l’utilizzo di microrganismi ha un ruolo fondamentale nelle pratiche di trasformazione di molecole potenzialmente tossiche quali gli idrocarburi, che quotidianamente vengono riversati negli ecosistemi provocando fenomeni di antropizzazione in equilibri naturali particolarmente sensibili. Numerosi ceppi batterici sono abili degradatori e mineralizzatori di sostanze inquinanti xenobiotiche di sintesi e recalcitranti non esistenti in natura, quali i derivati di idrocarburi aromatici e policlorobifenili (PCB). Mediante colture su mezzo minerale Bushnell-Haas agarizzato (BH) in presenza di una miscela di idrocarburi come unica fonte di carbonio sono stati isolati 5 cepp…
