Generalized coherence and connection property of imprecise conditional previsions.

2008

In this paper we consider imprecise conditional prevision assessments on random quantities with finite set of possible values. We use a notion of generalized coherence which is based on the coherence principle of de Finetti. We consider the checking of g-coherence, by extending some previous results obtained for imprecise conditional probability assessments. Then, we study a connection property of interval-valued gcoherent prevision assessments, by extending a result given in a previous paper for precise assessments.

Coherent Conditional Previsions and Proper Scoring Rules

2012

In this paper we study the relationship between the notion of coherence for conditional prevision assessments on a family of finite conditional random quantities and the notion of admissibility with respect to bounded strictly proper scoring rules. Our work extends recent results given by the last two authors of this paper on the equivalence between coherence and admissibility for conditional probability assessments. In order to prove that admissibility implies coherence a key role is played by the notion of Bregman divergence.

On general conditional random quantities

2009

In the first part of this paper, recalling a general discussion on iterated conditioning given by de Finetti in the appendix of his book, vol. 2, we give a representation of a conditional random quantity $X|HK$ as $(X|H)|K$. In this way, we obtain the classical formula $\pr{(XH|K)} =\pr{(X|HK)P(H|K)}$, by simply using linearity of prevision. Then, we consider the notion of general conditional prevision $\pr(X|Y)$, where $X$ and $Y$ are two random quantities, introduced in 1990 in a paper by Lad and Dickey. After recalling the case where $Y$ is an event, we consider the case of discrete finite random quantities and we make some critical comments and examples. We give a notion of coherence fo…

Geography Tests for Grade 7 in Accordance with Contemporary Educational Purposes

2018

Pārbaudes darbs – ir svarīgs mācību rezultātu novērtēšanas instruments, kuram ir jāatbilst sabiedrības vajadzībām un skolēnu īpašībām. Informācijas pieejamība un strauja maiņa izvirza pārbaudes darbu sastādītājiem jaunas prasības, kas ir labāk piemērotas skolēnu spēju novērtēšanai. Mūsdienās ir svarīgi novērtēt skolēnu augstākā izziņu līmeņa jeb domāšanas spējas: prasmes operēt ar informāciju, analizēt, risināt problēmsituācijas, radoši un kritiski domāt. Pētījuma rezultātā ir noskaidrots, kā pārbaudes darbi ģeogrāfijā 7.klasēm nespēj nodrošināt augstāka līmeņa prasmju novērtēšanu, bet pašiem skolēniem ir grūtības šādu spēju novērtējošo uzdevumu izpildē. Tomēr augstākā līmeņa uzdevumu izpil…

Efficient checking of coherence and propagation of imprecise probability assessments

2000

We consider the computational difficulties in the checking of coherence and propagation of imprecise probability assessments. We examine the linear structure of the random gain in betting criterion and we propose a general methodology which exploits suitable subsets of the set of values of the random gain. In this way the checking of coherence and propagation amount to examining linear systems with a reduced number of unknowns. We also illustrate an example.

Probabilistic Logic under Coherence: Complexity and Algorithms

2005

In previous work [V. Biazzo, A. Gilio, T. Lukasiewicz and G. Sanfilippo, Probabilistic logic under coherence, model-theoretic probabilistic logic, and default reasoning in System P, Journal of Applied Non-Classical Logics 12(2) (2002) 189---213.], we have explored the relationship between probabilistic reasoning under coherence and model-theoretic probabilistic reasoning. In particular, we have shown that the notions of g-coherence and of g-coherent entailment in probabilistic reasoning under coherence can be expressed by combining notions in model-theoretic probabilistic reasoning with concepts from default reasoning. In this paper, we continue this line of research. Based on the above sem…

Measuring the Economic, Environmental, and Social Sustainability of Short Food Supply Chains

2019

The production and distribution of food are among the hot topics debated in the context of sustainable development. Short food supply chains (SFSCs) are now widely believed to be more sustainable in comparison to mass food delivery systems. To date, very little quantitative evidence exists on the impacts of various types of food supply chains. Using a cross-sectional quantitative approach, this study assesses the sustainability of distribution channels in short and long food supply chains based on 208 food producers across seven countries: France, Hungary, Italy, Norway, Poland, the United Kingdom, and Vietnam. Ten distribution channel types are used in this study. To provide a comprehensiv…

Developing placement assessment in integration training for adult migrants in Finland

2017

As part of integration training in Finland, migrants are provided with Finnish or Swedish language courses. The linguistic objective is to provide migrants with the basic language skills required in daily life. To find the most suitable teaching group for learners in integration training, a placement assessment is carried out. This includes assessment of learners’ current proficiency level in the target language and study skills/experience. In this article we describe a project to develop a national test system for placement assessment (see Ohranen et al. 2015). En Finlande, des migrants adultes suivent des cours de finnois ou de suédois dans le cadre d’une formation pour l’intégration. L’o…
