In this work we investigate the sensitivity of individual researchers’ productivity rankings to the time of citation observation. The analysis is based on observation of research products for the 2001–2003 triennium for all research staff of Italian universities in the hard sciences, with the year of citation observation varying from 2004 to 2008. The 2008 rankings list is assumed the most accurate, as citations have had the longest time to accumulate and thus represent the best possible proxy of impact. By comparing the rankings lists from each year against the 2008 benchmark we provide policy-makers and research organization managers a measure of trade-off between timeliness of evaluation execution and accuracy of performance rankings. The results show that with variation in the evaluation citation window there are variable rates of inaccuracy across the disciplines of researchers. The inaccuracy results negligible for Physics, Biology and Medicine. 相似文献

Because of the variations in citation behavior across research fields, appropriate standardization must be applied as part of any bibliometric analysis of the productivity of individual scientists and research organizations. Such standardization involves scaling by some factor that characterizes the distribution of the citations of articles from the same year and subject category. In this work we conduct an analysis of the sensitivity of researchers’ productivity rankings to the scaling factor chosen to standardize their citations. To do this we first prepare the productivity rankings for all researchers (more than 30,000) operating in the hard sciences in Italy, over the period 2004–2008. We then measure the shifts in rankings caused by adopting scaling factors other than the particular factor that seems more effective for comparing the impact of publications in different fields: the citation average of the distribution of cited-only publications. 相似文献

The paper aims to perform a review of studies on elder abuse in Italy. Hand searching was undertaken of grey literature and reviews of published papers concerning local, national, and cross-national studies, both in Italian and English languages. Inferences mainly about perception and prevalence, types and risk factors, but also concerning victims and perpetrators when data were available, have been derived through the quantitative and qualitative information collected. On the whole, elder abuse in Italy, with a prevalence rate around 10–14%, is characterized by more female victims, especially in the oldest age groups. The risk of psychological abuse is highest, but the level of financial mistreatment is also high. In domestic settings, difficulties of overburdened family caregivers have been associated with the existence of possible episodes of abuse, which often remain hidden. In institutional settings, neglect of dependent persons, expired medications and lack of hygienic conditions represent the most common forms of reported abuse, uncovered with the help of police inspections. In both settings, the use of physical restraints emerges as an area of concern. Although caution is needed in relation to generalization, the available data suggest the existence of a widespread phenomenon of elder abuse in Italy. But more in-depth research is needed to provide further evidence and to raise the currently relatively low general and professional awareness of elder abuse. Moreover, a dedicated legal framework and protocol for tackling and preventing the phenomenon, and ad hoc support services for the victims, need to be urgently addressed. 相似文献

In today's complex business landscape it is critical to identify and understand what are the knowledge-based value drivers affecting business value creation. This paper focuses on the relevance of the emotive knowledge as a key knowledge asset shaping organisational capabilities of 21st century organisations. The concept of emotive knowledge is analysed in accordance with a twofold perspective. On the one hand, it is considered as a driver of people's engagement, and on the other it is viewed as a key factor affecting the creation of intangible value to be incorporated into organisational infrastructures and products. 相似文献

The main advantage of a multi-technique non-invasive artwork investigations relies on the use of different spectroscopic techniques that give rise to complementary information. Despite the artworks complexity, this approach allows great insight into the artwork composition and alteration phases. However, difficulties arise from the great amount of heterogeneous interconnected data that has to be stored for a prompt analysis and preserved. A suitable tool to handle and analyse all the information on the fly is therefore crucial to optimize work, specially in in situ investigations. In this paper we present MOVIDA, a new tool for the data management and analysis of non-invasive investigations in the Cultural Heritage field that not only allows the digital preservation of all the information and knowledge, but can also be used as an analytical tool while the investigation is being developed. The software can be installed on any computer to record, elaborate and analyse the data on-the-spot. All the data generated can be managed within the same application and the information can be easily consulted, compared and related to the corresponding areas of the artwork. The software is self-comprehensive and user-friendly and can be used by all the professionals involved in the investigation and preservation of Cultural Heritage whatever their background and computer skills are. 相似文献

ABSTRACT The restoration of the Roman building of the third-fourth century CE called Minerva Medica, in Rome, highlighted a problem concerning the choice of the color of the bricks for integration. Current conservation practice in Italy favours a restoration that as much as possible is consistent with the original but leaves some visible differences to a careful observer. Color measurement is usually performed using portable spectrocolorimeters that provide the reflectance spectrum and also colorimetric parameters such as L* a* b*, h* L* C*, RGB, etc. In other sectors, such as for olive oils, for wines, and also for the colors of commercial products, sensory panels are used to provide results of difference/similarity and are known to be similar to observations made by consumers. In this study, data from a top quality spectrocolorimeter and from a sensory panel are compared. Twenty non-professional people were involved in the comparison between seven restoration bricks and three ancient Roman bricks from the studied site. Observations took place in a room with controlled lighting, and each observer filled out a sensory card using about 2000 known comparison colors. Comparison of the results was carried out with graphic methods and by means of cluster analysis. The results show that the sensory panel could be a useful alternative to colorimetry, while cluster analysis allowed a significant response to questions posed by conservation professionals, and was confirmed by other graphic-statistical methods. 相似文献

We propose an operationalization of the rural and urban analogy introduced in Becher and Trowler (2001). According to them, a specialism is rural if it is organized into many, smaller topics of research, with higher author mobility among them, lower rate of collaboration and productivity, lower competition for resources and citation recognitions compared to an urban specialism. It is assumed that most humanities specialisms are rural while science specialisms are in general urban: we set to test this hypothesis empirically. We first propose an operationalization of the theory in most of its quantifiable aspects. We then consider specialisms from history, literature, computer science, biology, astronomy. Our results show that specialisms in the humanities present a sensibly lower citation and textual connectivity, in agreement with their organization into more, smaller topics per specialism, as suggested by the analogy. We argue that the intellectual organization of rural specialisms might indeed be qualitative different from urban ones, discouraging the straightforward application of citation-based indicators commonly applied to urban specialisms without a dedicated re-design in acknowledgement of these differences. 相似文献
