Structuring a System Dynamics Model using Group Model Building : Case Study on Flight Test Human Resources
2019
This paper presents a method that allows capture and organization of mental models of all levels of Stakeholders in order to elaborate a System Dynamics Model closer to the reality and more effective on Strategy proposition. This is done through information raised on the application of Group Model Building (GMB), and using PSM specific tools, like Mental Maps and Cognitive Maps. All these tools allow merge opinions and elicitate knowledge from many stakeholders involved on the process. In order to demonstrate the method’s suitability, it was applied on a Case Study to develop a System Dynamics Model for the Flight Test Specialized Human Resources Career Flow. The method has five stages: fir…
Avvertenze per il consumatore e obblighi delle piattaforme del commercio elettronico: alcune osservazioni sulla sentenza Lee v. Amazon
2022
La Proposition 5 è una legge californiana che attribuisce ai consumatori il diritto ad essere informati circa l’esposizione a sostanze cancerogene o che possano dar luogo a malformazioni congenite o ad altri danni riproduttivi: ai sensi della legge, tutti gli attori del circuito distributivo sono tenuti a fornire un’avvertenza «chiara e ragionevole» del relativo rischio. La sezione 230 del Communications Decency Act esonera da responsabilità gli intermediari della rete relativamente ai contenuti dei terzi. Le piattaforme del commercio elettronico, nel facilitare l’interazione di venditori ed acquirenti, rischiano di mettere a repentaglio la salute dei consumatori, portando loro prodotti vie…
Power of Paradox: Grassroots Organizations’ Legitimacy Strategies Over Time
2021
Fringe stakeholders with limited resources, such as grassroots organizations (GROs), are often ignored in business and society literature. We develop a conceptual framework and a set of propositions detailing how GROs strategically gain legitimacy and influence over time. We argue that GROs encounter specific paradoxes over the emergence, development, and resolution of an issue, and they address these paradoxes using cognitive, moral, and pragmatic legitimacy strategies. While cognitive and moral strategies tend to be used consistently, the flexible and paradoxical use of pragmatic strategies has important consequences, both for GROs’ legitimacy and for their potential influence over powerf…
Creer que p. Consideraciones en torno a la creencia
2012
This article is intended as a contribution to our understanding of the nature of belief as a propositional attitude. After contextualizing the issue, we discuss and reject some accounts of belief as a gamble and as high (near to 1) subjective probability and argue for the claim that believing that p consists in merely attributing a higher subjective probability to p than to not-p being not-p any of p"s alternatives and all of them as a whole. Additionally, we propose that the question which a belief answers is crucial in order to determine the degree of belief and the reasons in its favor. Este artículo trata de profundizar en nuestra comprensión de la naturaleza de la creencia en tanto que…
The conceptualisation of austerity in the Portuguese, Spanish and Irish press
2017
The aim of this chapter is to analyse the conceptualisation of austerity in three different European cultures by identifying metaphorical expressions used in one representative newspaper of the Portuguese, the Spanish and the Irish press between 2011 and 2012. The metaphors were identified by searching for three keywords from the field of economy and politics (austeridade-austeridad-austerity, corte-recorte-cut and divida-deuda-debt) and were then classified according to the type of schema they instantiate, namely, propositional schema, image schema or event schema. Assuming the general framework of Cultural Linguistics and corpus-based and discourse-based approaches to conceptual metaphor,…
O zadawaniu pytań na lekcji języka polskiego. Studium przypadku
2020
The article presents the results of qualitative and quantitative analysis of questions asked during a single Polish language lesson. It consists of two main parts. The first presents and comments on the results of the teacher’s questions analysis, the second ‒ questions asked by students. The concept of Bogusław Skowronek was used, who distinguished four types of questions in his classification: 1) reassuring-instrumental; 2) substantive; 3) about the meta-didactic function; 4) not related to the classroom situation. The first two categories were specified in more detail by Elizabeth Perrott’s proposition, which distinguishes between guiding questions and questions for clarification among r…
Closed-Form Expressions for Global and Local Interpretation of Tsetlin Machines
2021
Tsetlin Machines (TMs) capture patterns using conjunctive clauses in propositional logic, thus facilitating interpretation. However, recent TM-based approaches mainly rely on inspecting the full range of clauses individually. Such inspection does not necessarily scale to complex prediction problems that require a large number of clauses. In this paper, we propose closed-form expressions for understanding why a TM model makes a specific prediction (local interpretability). Additionally, the expressions capture the most important features of the model overall (global interpretability). We further introduce expressions for measuring the importance of feature value ranges for continuous feature…
Truth, Negation and Meaning
2013
‘True’ and ‘False’ are defined through a linguistic rule requiring the negation operator. This is the elaboration of an idea proffered for the first time by the Stoics on the basis of some remarks by Aristotle and then in modern times by Frege and Wittgenstein. Another thesis of this essay is the following: the true/false rule is a sort of UR-Regel underlying all linguistic practices (including prayers and commands) and all human cultures. Reinterpreting the notion of Spielraum put forward by Wittgenstein in 4.463 of the Tractatus, I will present an implicational pragmatic theory of a true proposition. Jokes and reductio ad absurdum are explained as examples of Spielraum.
Erratum to “Irregularity” [Topology Appl. 154 (8) (2007) 1565–1580]
2012
[2, Proposition 4.4] states that each regular pretopology is topologically regular. Professor F. Mynard (Georgia Southern University) advised the authors that he was not convinced by the proof of that proposition, which enabled us to realize the proposition is wrong, as the example below shows. Recall that (e.g., [2]) a pretopology ξ on a set X is called regular if Vξ (x)⊂ adh ξ Vξ (x) (respectively, topologically regular if Vξ (x)⊂ cl ξ Vξ (x)) for every x ∈ X . As a consequence, in the sequel of [2], regular should be read topologically regular in a few instances, in particular in [2, Theorem 4.6]. [2, Proposition 4.4] is also quoted in [3], where it is used in some reformulations of clas…
Duties, Rules and Interpretations in Obligational Disputations
2001
An obligational disputation, as it was known in the Middle Ages, consisted basically of a sequence of propositions put forward by one person, called the opponent, and evaluated by another person, called the respondent. In the most typical variations of the technique, the sequence would begin with a special proposition, called the positum It was taken as the starting point, which the rest of the sequence would develop. The respondent had to accept the positum, if it was free from contradictions. Then he had to take into account in his later evaluations of the other propositions that he must at any time during the disputation grant the positum and anything following from it. The disputations …
