Nudging museums attendance: a field experiment with high school teens     

Patrizia Lattarulo  Marco Mariani  Laura Razzolini 《Journal of Cultural Economics》2017,41(3):259-277

This paper reports results from a field experiment conducted to study the effect of incentives offered to high school teens to motivate them to visit art museums. A vast literature exists on the design of incentives to modify the behavior of firms and consumers, but not much is known about incentives offered to adolescents and young adults to affect their cultural consumption behavior. Students in the first treatment receive a flier with basic information and opening hours of a main museum in Florence, Italy—Palazzo Vecchio. Students in the second treatment receive the flier and a short presentation conducted by an art expert about the exhibit; students in the third treatment, in addition to the flier and the presentation, receive also a non-financial reward in the form of extra-credit points toward their school grade. The analysis yields two main findings. First, non-financial reward is more effective at inducing the students to undertake the encouraged visit than either the simple presentation or the basic information with the flier. Second, over a longer time horizon the non-financial reward does not induce a significant change in behavior with respect to the simple presentation.  相似文献   

Branding of Flemish higher education institutions: a strategic balance perspective     

Jelle Mampaey  Jeroen Huisman  Marco Seeber 《高等教育研究与发展》2015,34(6):1178-1191

Branding of higher education institutions (HEIs) is an expanding area of research. The existing literature mainly draws on the strategic management perspective that argues that HEIs are pressured to develop brands which differentiate them from their competitors. Past studies, however, do insufficiently take into account that most HEIs are positioned in systems that contain both competitive pressures (to differentiate) and institutional pressures (to meet taken-for-granted expectations), where neither of the pressures is clearly dominant. Our multiple case study of the five Flemish universities finds that branding can simultaneously address competitive and institutional pressures and that the universities studied combine aspects of distinctiveness with elements of similarity.  相似文献   

Differential effects of reading trainings on reading processes: a comparison in Grade 2

Phonics, fluency, and reading strategy trainings are evidence-based interventions that foster the reading skills of poor readers in primary school. The purpose of the present study was to compare differential effects of the three types of trainings on the efficiency of component processes on word, sentence, and text level immediately after the training and at a 3-month follow-up. The 235 poor readers were randomly allocated to one of the reading interventions or to a control condition. All interventions consisted of 25 sessions that were scheduled twice a week and lasted 45 min. Results indicated short-term effects of the phonics training and the strategy training on the efficiency of a broad range of word-level and sentence-level processes. None of the treatment effects persisted over the long term, indicating the need for instructional efforts to regularly practice the acquired skills after the actual training.  相似文献   

On functional observers for linear systems with unknown inputs and HOSM differentiators     

Marco Tulio Angulo  Jaime A. Moreno  Leonid Fridman 《Journal of The Franklin Institute》2014

The problem of constructing functional observers for linear systems with unknown inputs is considered. Necessary and sufficient conditions for the existence of a proper observer (without differentiations) are revisited. A simple and explicit form of a functional observer is presented. It is shown that when such observer is not proper, it is still possible to use the High-Order Sliding Mode differentiator to implement it. Nevertheless, in such case, additional conditions on the system and the unknown input are required.  相似文献   

A new industry creation and originality: Insight from the funding sources of university patents     

Marco Guerzoni  T. Taylor Aldridge  David B. Audretsch  Sameeksha Desai 《Research Policy》2014

Scientific breakthroughs coming from universities can contribute to the emergence of new industries, such as in the case of biotechnology. Obviously, not all research conducted in universities leads to a radical change from existing technological trajectories. Patents and patent dynamics have long been recognized as critical in understanding the emergence of new technologies and industries. Specifically, patent citations provide insight into the originality of a discovery that has received patent protection. Yet while a large body of literature addresses the impact of patent originality on various firm performance measures, we address the question of what conditions drive patent originality in the process of knowledge creation within the university. Using data on patented cancer research, we examine how research context – as reflected by the funding source for each scientist – is associated with patent originality. We find that when university scientists are partly funded by their own university, they have a higher propensity to generate more original patents. By contrast, university scientists funded either by industry or other non-university organizations have a lower propensity to generate more original patents. The significance of our findings in the cancer research setting call for further research on this question in other research fields.  相似文献   

False negativity to carbohydrate-deficient transferrin and drugs: a clinical case     

Matteo Vidali  Vincenza Bianchi  Marco Bagnati  Nadia Atzeni  Andrea Marco Bianchi  Giorgio Bellomo 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2014,24(1):175-179

Introduction:

In this work we report on the possible effect of the medical therapy on CDT concentration in a chronic alcohol abuser, with known medical history (July 2007 – April 2012) and alcohol abuse confirmed by relatives.

Case history:

At the end of 2007, patient displayed the following laboratory results: AST 137 U/L, ALT 120 U/L, GGT 434 U/L, MCV 101 fL and CDT 3.3%. On December 2007, after double coronary artery bypass surgery, he began a pharmacological treatment with amlodipine, perindopril, atorvastatin, isosorbide mononitrate, carvedilol, ticlopidine and pantoprazole. In the next months, until may 2011, the patient resumed alcohol abuse, as confirmed by relatives; however, CDT values were repeatedly found negative (0.8% and 1.1%) despite elevated transaminases and GGT, concurrent elevated ethyl glucuronide concentration (> 50 mg/L) and blood alcohol concentration (> 1 g/L). Alcohol consumption still continued despite increasing disulfiram doses ordered by an Alcohol Rehab Center. On May 2011, the patient was transferred to a private medical center where he currently lives.

Conclusions:

This study suggests the possibility that a medical therapy including different drugs may hamper the identification of chronic alcohol abusers by CDT.  相似文献   

Assessment of thermo-hygrometric quality in museums: Method and in-field application to the “Duccio di Buoninsegna” exhibition at Santa Maria della Scala (Siena,Italy)     

Stefano Paolo Corgnati  Marco Filippi 《Journal of Cultural Heritage》2010,11(3):345-349

Maintaining the microclimatic parameters at the desired value is essential for artefacts preservation. In order to control the status of the microclimatic parameters, a continuous monitoring of the indoor environmental provides conservators, curators, restorers, and lenders with an exact knowledge of the microclimatic conditions under which the works of art are kept. Moreover, the monitoring results give important information in order to make adequate changes to the control strategy of microclimatic parameters. From this point of view, monitoring is an essential tool to develop an actual preventive control programme aimed at maintaining the optimal microclimatic conditions for preservation. As a consequence, long-term monitoring has to be applied to prevent deterioration of works of art. The widespread opinion that a correct approach to the topic of microclimate control for artefacts preservation is not only and necessarily to provide buildings with sophisticated environmental control systems, but mainly to investigate the actual environmental dynamics and, before any structural intervention, to define the compatibility between the climate control potentials and the preservation requirements, has become more and more firm among the experts. Monitoring also allows to verify the capacity of the “building and Heating, Ventilation and Air Conditioning (HVAC)” system to maintain the desired thermo-hygrometric values within the operating conditions. To this aim, the Italian Standard UNI 10829 (1999) defining monitoring, elaboration and analysis of the microclimatic data as supporting actions for artefacts preservation, led to the need of a long-term monitoring and of a statistical approach to the data management. The approach proposed by the Italian Standard has been recently adopted by a European Standard (EN 15251, 2007). In accordance with the Standards mentioned above, in this paper an operational procedure to assess the thermo-hygrometric quality in museums is firstly synthetically presented and than applied to a case study. In particular, the procedure is developed in order to define the thermo-hygrometric quality level of the exhibition areas in the large museum complex of “Santa Maria della Scala” in Siena (Italy) during the international temporary exhibition “Duccio. La nascita della pittura senese” (“Duccio. The birth of Sienese Painting”).  相似文献

The Evolution of Interaction Shape in Differential Susceptibility          下载免费PDF全文

Marco Del Giudice 《Child development》2017,88(6):1897-1912

Expectations about the shape of statistical interactions play a crucial role in the study of differential susceptibility and other types of person–environment interplay. These expectations shape methodological guidelines and inform the interpretation of empirical findings; however, their logic has never been explicitly examined. This study is the first systematic exploration of the evolution of interaction shape in differential susceptibility. The model introduced here yields a number of novel insights; for example, interactions in differential susceptibility should usually be asymmetric and likely to be biased toward the prototypical shape of diathesis–stress models. This article also presents an exploratory analysis of interaction shape in recent empirical studies and ends with a discussion of the theoretical and methodological implications of the present findings.  相似文献   

On the Shapley value and its application to the Italian VQR research assessment exercise     

Camil Demetrescu  Francesco Lupia  Angelo Mendicelli  Andrea Ribichini  Francesco Scarcello  Marco Schaerf 《Journal of Informetrics》2019,13(1):87-104

Research assessment exercises have now become common evaluation tools in a number of countries. These exercises have the goal of guiding merit-based public funds allocation, stimulating improvement of research productivity through competition and assessing the impact of adopted research support policies. One case in point is Italy's most recent research assessment effort, VQR 2011–2014 (Research Quality Evaluation), which, in addition to research institutions, also evaluated university departments, and individuals in some cases (i.e., recently hired research staff and members of PhD committees). However, the way an institution's score was divided, according to VQR rules, between its constituent departments or its staff members does not enjoy many desirable properties well known from coalitional game theory (e.g., budget balance, fairness, marginality). We propose, instead, an alternative score division rule that is based on the notion of Shapley value, a well known solution concept in coalitional game theory, which enjoys the desirable properties mentioned above. For a significant test case (namely, Sapienza University of Rome, the largest university in Italy), we present a detailed comparison of the scores obtained, for substructures and individuals, by applying the official VQR rules, with those resulting from Shapley value computations. We show that there are significant differences in the resulting scores, making room for improvements in the allocation rules used in research assessment exercises.  相似文献
