Conjunction and Disjunction Among Conditional Events

2017

We generalize, in the setting of coherence, the notions of conjunction and disjunction of two conditional events to the case of n conditional events. Given a prevision assessment on the conjunction of two conditional events, we study the set of coherent extensions for the probabilities of the two conditional events. Then, we introduce by a progressive procedure the notions of conjunction and disjunction for n conditional events. Moreover, by defining the negation of conjunction and of disjunction, we show that De Morgan’s Laws still hold. We also show that the associative and commutative properties are satisfied. Finally, we examine in detail the conjunction for a family \(\mathcal F\) of t…

Conditional Random Quantities and Compounds of Conditionals

2013

In this paper we consider finite conditional random quantities and conditional previsions assessments in the setting of coherence. We use a suitable representation for conditional random quantities; in particular the indicator of a conditional event $E|H$ is looked at as a three-valued quantity with values 1, or 0, or $p$, where $p$ is the probability of $E|H$. We introduce a notion of iterated conditional random quantity of the form $(X|H)|K$ defined as a suitable conditional random quantity, which coincides with $X|HK$ when $H \subseteq K$. Based on a recent paper by S. Kaufmann, we introduce a notion of conjunction of two conditional events and then we analyze it in the setting of cohere…

Generalized probabilistic modus ponens

2017

Modus ponens (from A and “if A then C” infer C) is one of the most basic inference rules. The probabilistic modus ponens allows for managing uncertainty by transmitting assigned uncertainties from the premises to the conclusion (i.e., from P(A) and P(C|A) infer P(C)). In this paper, we generalize the probabilistic modus ponens by replacing A by the conditional event A|H. The resulting inference rule involves iterated conditionals (formalized by conditional random quantities) and propagates previsions from the premises to the conclusion. Interestingly, the propagation rules for the lower and the upper bounds on the conclusion of the generalized probabilistic modus ponens coincide with the re…

Transitive Reasoning with Imprecise Probabilities

2015

We study probabilistically informative (weak) versions of transitivity by using suitable definitions of defaults and negated defaults in the setting of coherence and imprecise probabilities. We represent \(\text{ p-consistent }\) sequences of defaults and/or negated defaults by g-coherent imprecise probability assessments on the respective sequences of conditional events. Finally, we present the coherent probability propagation rules for Weak Transitivity and the validity of selected inference patterns by proving p-entailment of the associated knowledge bases.

How does disruptive innovation influence the funding decisions of different venture capital investors? An empirical analysis on the role of startups'…

2023

Entrepreneurs present their ideas in a favorable light through compelling communications that may shape the investors' impressions about the value of the startup's technology and its potential to disrupt. Assessing such communications, venture capital (VC) investors get an impression of the startup's technology and shape their willingness to commit resources to it. Since diverse kinds of VC investors pursue alternative investment objectives, they may develop different impressions of the startup's technology and accordingly make different resource commitment decisions. This paper aims to investigate the resource commitment decisions of VC investors when financing startups communicating disru…

Trust, mistrust and distrust as blind spots of Social Licence to Operate: illustration via three forerunner countries in nuclear waste management

2021

The notion of social licence to operate (SLO) has become a widely applied concept for companies in mining and resource extraction industries to manage their social and community relations, in the face of local criticism and opposition. SLO literature and practice have highlighted earning the trust of the local community as a key requirement for an SLO. This article addresses three weaknesses in how the current SLO literature addresses trust. The arguments are illustrated via examples from nuclear waste management in Finland, France and Sweden–three forerunners in implementing high-level nuclear waste repository projects. Nuclear waste management constitutes a relevant case for analysis, as …

Unravelling the moderating effects of size and experience on product innovations and exports: a study in a medium knowledge-intensive industry

2012

This paper contributes to improve our knowledge on the important role of product innovation in export strategy by introducing the moderating effects of organizational variables. We argue that in a medium knowledge-intensive industry, these variables might strengthen the relationship between innovations and exports. Research on innovation and export strategy has addressed these issues increasingly during last decades; however, the divergence on the empirical approaches difficult the understanding of the linkages among variables, which are highly dependent on the industry technological characteristics. We carry out a time-lagged study using the literature-based innovation output (LBIO) method…

Asymmetric behaviour of biotechnology business patterns in Spain

2009

Since the end of the 90s there has been an increase in the emergence of biotechnology industries in Spain, partially as a result of growing support from institutionally based infrastructures. Through the use of empirical fieldwork, this study aims to reveal how future prospects are not as optimistic as most Spanish agents perceive. Our conclusions are based on the asymmetric behaviour shown by Spanish biotechnology firms in their business models. This asymmetry is based on the overwhelming dominance of business models centred on low investment, limited R&D expenditure and minor or incremental innovation, whereas the long term–long return model, which prevails in the leading countries in thi…

The Road to Parnassus. Artist Strategies in Contemporary Art. Rise and Success of Glasgow artist Douglas Gordon and of the wider YBA generation

2015

How can one become a successful artist? Where should one start a career in the art world? What are useful strategies to achieve recognition in the art system? Such questions hoard in students' minds ever since entering art school and they probably chase every kind of art professional who is at an early career stage. “The Road to Parnassus” tries to understand what makes a good start in today's art world, who are influential players in the field and which strategies might apply. The swift career ascension of Glasgow artist Douglas Gordon – one of today's leading visual artists – and of the broader YBA generation that rose into worldwide prominence in the 1990s – Damien Hirst and Sarah Lucas …
