Designing the engaging Energy-Box Bridging the gap between energy control systems and users' energy awareness
No full textThis work describes a design experience focused on the theme of eco-feedback, a technology complementary to traditional energy control systems and meant to obtain additional savings by increasing the awareness of the users about the factors that determine energy consumption. This experience, held during a multidisciplinary ideation workshop and involving students and researchers at the University of Toulouse, was focused on the conceptual design of an Energy-Box, conceived as an artefact (or a set of artefacts) for making people inhabiting the University campus aware of energy issues and leading them to more energy conscious lifestyles. Three different proposals stemmed from this experience, that were evaluated first by the participants to the workshop themselves and then, some months later, by 80 undergraduate students of the University of Venice working on the same themes. We extracted interesting lesson learned from this evaluation, that should be taken into account for the development of user's centred eco-feedback systems in public contexts
Analysing and exemplifying forensic conclusion criteria in terms of Bayesian decision theory
No full textThere is ongoing discussion in forensic science and the law about the nature of the conclusions reached based on scientific evidence, and on how such conclusions – and conclusion criteria – may be justified by rational argument. Examples, among others, are encountered in fields such as fingermarks (e.g., ‘this fin- germark comes from Mr. A’s left thumb’), handwriting examinations (e.g., ‘the questioned signature is that of Mr. A’), kinship analyses (e.g., ‘Mr. A is the father of child C’) or anthropology (e.g., ‘these are human remains’). Considerable developments using formal methods of reasoning based on, for example (Bayesian) decision theory, are available in literature, but currently such reference principles are not explicitly used in operational forensic reporting and ensuing decision-making. Moreover, applied examples, illustrating the principles, are scarce. A potential consequence of this in practical proceedings, and hence a cause of concern, is that underlying ingredients of decision criteria (such as losses quantifying the undesirability of adverse decision consequences), are not properly dealt with. There is merit, thus, in pursuing the study and discussion of practical examples, demonstrating that formal decision-theoretic principles are not merely conceptual considerations. Actually, these principles can be shown to underpin practical decision-making procedures and existing legal decision criteria, though often not explicitly apparent as such. In this paper, we will present such examples and discuss their properties from a Bayesian decision-theoretic perspec- tive. We will argue that these are essential concepts for an informed discourse on decision-making across forensic disciplines and the development of a coherent view on this topic. We will also emphasize that these principles are of normative nature in the sense that they provide standards against which actual judg- ment and decision-making may be compared. Most importantly, these standards are justified independently of peoples’ observable decision behaviour, and of whether or not one endorses these formal methods of reasoning
Economia e Politica Agraria
No full textIl testo mira a far conoscere le caratteristiche del settore agricolo, il suo processo evolutivo ed il nuovo ruolo che l'agricoltura ed il sistema agroalimentare stanno assumendo nel contesto dell'economia nazionale e globale, alla luce dei recenti orientamenti di Politica agricola comunitaria, di fronte alle esigenze, sempre più sentite, di qualità e sicurezza alimentare dei consumatori. Si propone di offrire una chiave di lettura per la comprensione dei principi e degli strumenti dell’Economia e Politica Agraria, nell’interpretazione del ruolo che essa svolge per la Società nel suo divenire.The text aims to raise awareness of the characteristics of the agricultural sector, its evolutionary process and the new role that agriculture and the agri-food system are taking in the context of the national and global economy, in light of the recent guidelines of the Community agricultural policy (CAP), facing the increasingly needs of consumers' quality and food safety. It is proposed to offer a key to understanding the principles and tools of Agricultural Economy and Policy, in the interpretation of the role that it plays for the Society

No full textThe 10Be record as a proxy of paleomagnetic reversals and excursions: A Mediterranean perspective
No full textThe 10Be/9Be ratio is acknowledged as an effective tool for establishing the stratigraphic position of paleomagnetic excursions. Still, our data suggest that, in particular depositional settings, the interplay between climate, sedimentation and oceanography may jeopardize a realistic depiction of the natural 10Be/9Be record
Tailoring the interfacial structure of colloidal "giant" quantum dots for optoelectronic applications
No full textColloidal semiconductor quantum dots (QDs) are promising building blocks for the realization of future optoelectronic technologies, thanks to their size-tunable electronic and optical properties. Among various types of QDs, colloidal "giant" QDs (g-QDs, core/thick-shell) have been widely used in different applications, such as solar cells, light emitting devices, luminescent solar concentrators and photoelectrochemical (PEC) hydrogen production. However, g-QDs have a thick-shell which serves as a physical barrier for electron and hole transfer, leading to a slow charge transfer rate. In this work, we synthesized CdSe/CdSexS1-x/CdS core/shell/shell g-QDs with an intermediate CdSexS1-x alloyed layer. The presence of this interfacial layer largely improves the absorption of CdSe/CdS QDs, particularly in the 300-650 nm range. By engineering the interfacial layer, the holes can leak more into the CdS shell region compared to that of CdSe/CdS QDs. PEC devices based on alloyed g-QDs exhibit a 20% higher saturated photocurrent density (11 ± 0.5 mA cm-2) compared to CdSe/CdS QDs. In addition, after one-hour illumination (100 mW cm-2), the PEC cell based on alloyed g-QDs still exhibits a photocurrent density of 7.5 mA cm-2, maintaining 70% of its initial value. Such alloyed g-QDs are very promising for several emerging optoelectronic applications, where charge separation, transfer and transport play a critical role for the realization of high performance devices
