The Decision Making Tendency Inventory: A new measure to assess maximizing, satisficing, and minimizing
2015
Abstract We introduce the Decision Making Tendency Inventory (DMTI), a new scale for measuring the decision-making tendencies to maximize, to satisfice, and to minimize. The scale has promising psychometric properties. Our findings show that the revealed tendencies are independent from each other and from the specific decision-making domain. Each factor is differently related to a set of indices of well-being and functioning, suggesting intriguing considerations regarding the distinctive characteristics of maximizing, satisficing, and minimizing. The DMTI extends previous research on maximizing and might contribute to explain the inconsistent results in the literature. Directions for future…
Understanding short- and long-term implications of “myopic” fleet maintenance policies: a system dynamics application to a city bus company
2010
Financial losses recorded in city bus companies often force managers to implement restructuring strategies aimed at improving business results. However, such decisions may not produce the expected consequences for a number of reasons. Both the internal and external environment in which such companies operate can make the design and implementation of long-term sustainable policies quite difficult. In fact, the result may be that decision makers introduce "effective" policies in a company subsystem, while ignoring the medium- and long-term implications of such decisions in the performance of the whole company. With the aim to detect the main causes underlying "myopic" fleet maintenance polici…
The effects of using participatory working time scheduling software on working hour characteristics and wellbeing : a quasi-experimental study of irr…
2020
Background: Studies in the health care sector indicate that good work time control is associated with better perceived wellbeing but also with non-ergonomic work schedules, such as compressed work schedules. Participatory working time scheduling is a collaborative approach to scheduling shift work. Currently, there is a lack of information on whether working hour characteristics and employees' wellbeing in irregular shift work change after implementing participatory working time scheduling. Objective: To investigate the effects of using digital participatory working time scheduling software on working hour characteristics and well-being among Finnish hospital employees. Participants and met…
Analog Photonic Fractional Signal Processing
2018
In this work, we provide an up to date overview on the subject of photonic fractional signal processing, including both, in-fiber and waveguide on-chip technology. Thus, we discuss in detail fractional differentiation, fractional integration, fractional Hilbert transforms, and finally, fractional Fourier transforms. In each case, the underlying mathematical principles are explained for each operation, together with a short historical discussion in the context of classical optics. After that, the different proposals to perform these operations photonically on the complex field envelope of a given light pulse are presented, divided according to its working principle. Finally, current applicat…
A new decision model for economic evaluation of novel therapies for HCV
2014
In 2014, the European Medicines Agency (EMA) has given the license to two new direct-acting antiviral: sofosbuvir and simeprevir. The evidence provided by the studies, reported a high rate of SVR even in patients with decompensated cirrhosis. This and other innovative elements are potentially adept at changing the entire natural course of HCV. However, the dramatic prevalence rates of HCV observed in Italy, and the high prices that are expected to be required by the pharmaceutical industry, raises some critical issues about how to regulate access to such drugs. The objective of this article is to present a new decision model for the evaluation of novel therapies for HCV. This model is inten…

Links and Bifurcations in Nonsingular Morse–Smale Systems
1997
Wada's theorem classifies the set of periodic orbits in NMS systems on S3 as links, that can be written in terms of six operations. This characterization allows us to study the topological restrictions that links require to suffer a given codimension one bifurcation. Moreover, these results are reproduced in the case of NMS systems with rotational symmetries, introducing new geometrical tools.
Beilinson Motives and Algebraic K-Theory
2019
Section 12 is a recollection on the basic results of stable homotopy theory of schemes, after Morel and Voevodsky. In particular, we recall the theory of orientations in a motivic cohomology theory. Section 13 is a recollection of the fundamental results on algebraic K-theory which we translate into results within stable homotopy theory of schemes. In particular, Quillen’s localization theorem is seen as an absolute purity theory for the K-theory spectrum. In Section 14, we introduce the fibred category of Beilinson motives as an appropriate Verdier quotient of the motivic stable homotopy category. Using the Adams filtration on K-theory, we prove that Beilinson motives have the properties o…
: Difficulties ans risks of interSME cooperation : solutions provided by private-equity firms
2016
L’article analyse les difficultés et risques auxquels font face les petites et moyennes entreprises (PME) lors de la formation de coopérations interfirmes, et les rôles joués par les sociétés de capital-investissement dans leur diminution. Les PME font principalement face à une asymétrie informationnelle et une incertitude accrues en comparaison aux entreprises plus grandes. Les sociétés de capital-investissement permettent de réduire ces deux facteurs et d’instaurer une situation de confiance entre les futurs cocontractants, ce qui évite l’échec de la transaction. Une étude de cas multiples à visée infirmationniste menée sur le marché français du capital-investissement détaille ces princip…
Are social and entrepreneurial attitudes compatible?
2012
PurposeThe aim of this paper is to analyze the compatibility between entrepreneurial and social attitudes. Specifically, it seeks to analyze whether subjects with a more developed economic entrepreneurial attitude exhibit a less social attitude.Design/methodology/approachThe methodology integrates an economic experimental approach with a standard entrepreneurial intention questionnaire to analyze the interaction between entrepreneurial and social self‐perceptions and behavior.FindingsThere is empirical evidence that experimental entrepreneurial behavior (characterized by detecting an opportunity and accepting risk to take an economic advantage from it in laboratory experiments) reduces the …
