Improvisation for innovation: The contingent role of resource and structural factors in explaining innovation capability
2018
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link. This paper focuses on resource and structural factors to explore the relationship between organizational improvisation and innovation capability. Although the role of improvisation has attracted increasing academic attention in fast-changing environments, little is known about the conditions under which firms benefit from improvisation. This paper addresses this gap using an organizational learning perspective that explains the role of a firm's organizational structure and organizational resources for improvisation and innovation. A large-scale …
Implementation aspects of interactive multiobjective optimization for modeling environments: The case of GAMS-NIMBUS
2014
Abstract. Interactive multiobjective optimization methods have provided promising results in the literature but still their implementations are rare. Here we introduce a core structure of interactive methods to enable their convenient implementation. We also demonstrate how this core structure can be applied when implementing an interactive method using a modeling environment. Many modeling environments contain tools for single objective optimization but not for interactive multiobjective optimization. Furthermore, as a concrete example, we present GAMS-NIMBUS Tool which is an implementation of the classification-based NIMBUS method for the GAMS modeling environment. So far, interactive met…
Case assignment, case concord, and quantificational case constructions
2011
Abstract This paper examines a controversial and particularly complex case phenomenon called quantificational case attested in a number of historically unrelated Slavonic and Finno-Ugric languages, and attempts to establish certain novel cross-linguistic generalizations and conclusions. In particular, it will be argued that (i) instead of standard one-to-one case assignment, in which one case assigner is case-related to one case assignee, a many-to-many case flow is attested; (ii) nominal case is not a privilege of full DPs, arguments or thematic roles; (iii) case reflects either local or nonlocal functional structure, whether in the verbal or nominal domain; and that (iv) there is no disti…
Intersectionalities, dis/abilities and subjectification in deaf LGBT people: An exploratory study in Sicily
2016
The article discusses the multiple discrimination, normalization and stigmatization experienced by deaf LGBT youth in Sicily, Italy, on the basis of a study of their everyday life (specifically school years and peer interactions). So far in Italy, very little attention has been paid to multiple discrimination and, specifically, to homophobic violence towards disabled individuals. It is, therefore, impossible to consider any valid sampling of the desired population and very few reports have been produced. The authors, a sociologist and a psychologist, carry out an analysis of the results obtained from interviews with 15 LGBT individuals recruited through social networks, thematic chats, and …
In praise of artifice reloaded: Caution with natural image databases in modeling vision
2019
Subjective image quality databases are a major source of raw data on how the visual system works in naturalistic environments. These databases describe the sensitivity of many observers to a wide range of distortions of different nature and intensity seen on top of a variety of natural images. Data of this kind seems to open a number of possibilities for the vision scientist to check the models in realistic scenarios. However, while these natural databases are great benchmarks for models developed in some other way (e.g., by using the well-controlled artificial stimuli of traditional psychophysics), they should be carefully used when trying to fit vision models. Given the high dimensionalit…
What is Experience? : Foucauldian Perspectives
2019
Michel Foucault’s (1926–1984) thought is widely used in the humanities and social sciences for investigating experiences of madness, illness, marginalization and social conflicts. However, the meaning of the word “experience” is not always clearly defined, and the French word expérience has a whole variety of meanings. In this article I explicate Foucault’s most relevant concepts of experience and their theoretical functions. He refers to experience throughout his career, especially in his early texts on existential psychiatry from the 1950s and 1960s and in his late work from the 1980s. Texts such as Mental Illness and Psychology and Dire vrai sur soi-même have received less attention than…
Intraductal aspiration: a promising new tissue-sampling technique for the diagnosis of suspected malignant biliary strictures
2012
Brushing is the most commonly used technique for biliary sampling at ERCP, despite its limited sensitivity. To evaluate intraductal aspiration (IDA) as a new combined endoscopic technique for cytodiagnosis, its cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. Prospective, observational study. Single tertiary referral center. IDA cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. From April 2009 to September 2010, 42 consecutive patients with suspected malignant biliary stricture underwent ERCP, with tissue sampling obtained with IDA. IDA included performance of standard brushing in all patients. After standard brushing,…
Analysis of electrolyte abnormalities and the mechanisms leading to arrhythmias in heart failure. A literature review.
2016
About 50% of deaths from heart failure (HF) are sudden, presumably referable to arrhythmias. Electrolyte and acid-base abnormalities are a frequent and potentially dangerous complication in HF patients. Their incidence is almost always correlated with the severity of cardiac dysfunction; furthermore leading to arrhythmias, these imbalances are associated with a poor prognosis. The frequency of ventricular ectopic beats and sudden cardiac death correlate with both plasma and whole body levels of potassium, especially in alkalemia. The early recognition of these alterations and the knowledge of the pathophysiological mechanisms are useful for the management of these HF patients.
Trapping of quasiparticles of a nonequilibrium superconductor
2000
We have performed experiments where hot electrons are extracted from a normal metal into a superconductor through a tunnel junction. We have measured the cooling performance of such NIS junctions, especially in the cases where another normal metal electrode, a quasiparticle trap, is attached to the superconductor at different distances from the junction in direct metal-to-metal contact or through an oxide barrier. The direct contact at a submicron distance allows superior thermalization of the superconductor. We have analyzed theoretically the heat transport in this system. From both experiment and theory, it appears that NIS junctions can be used as refrigerators at low temperatures only w…
The Gauge Glass Transition
1993
Results of Monte Carlo simulations in three and four spatial dimensions of a simple model that seems to have the necessary ingredients for disordered type-II superconductor behavior in an external magnetic field are reported. The data suggest that in d = 3 dimensions there is a finite temperature phase transition at T ≈ 0.45 into a truly superconducting vortex glass phase with infinite d.c. conductivity The (effective) correlation length exponent v and the dynamic critical exponent z at this transition are in good agreement with experiments. In d = 4 dimensions the gauge glass transition is located at T ≈ 0.95. It is concluded that the lack of time reversal symmetry in the model places it i…
