Scientific Foundation of Business Models Theory: Research Traditions Approach

During the last two decades, the literature in management studies has shown a significant increase in interest in the theory of business models, and there has been wide-ranging discussion about the definitions of those models. These studies and discussions have provoked questions about the scientific nature of the foundations of business models. This article attempts to verify whether the proposed constructions of business models meet the objectives of abduction, which is, according to the methodology of science, one of the recognised methods to verify the scientific nature of created theories. The verification was performed by using the method of the Scientific Research Tradition (ScRT) by Larry Laudan. The result unequivocally confirmed that the theory of business models that is created and defined based on management sciences falls under the scope of ScRT. It can be said that according to the methodology of science, the business models theory proposed on the basis of management science points to abduction as a tool that allows for a deeper understanding of the mechanisms of formation and opens a new way of interpretation than is the case when using deduction or induction.     

Pure Modal Logic of Names and Tableau Systems

By a pure modal logic of names (PMLN) we mean a quantifier-free formulation of such a logic which includes not only traditional categorical, but also modal categorical sentences with modalities de re and which is an extension of Propositional Logic. For categorical sentences we use two interpretations: a “natural” one; and Johnson and Thomason’s interpretation, which is suitable for some reconstructions of Aristotelian modal syllogistic (Johnson in Notre Dame J Form Logic 30(2):271–284, 1989; Thomason in J Philos Logic 22(2):111–128, 1993 and J Philos Logic 26:129–141, 1997. In both cases we use Johnson-like models (1989). We also analyze different kinds of versions of PMLN, for both general and singular names. We present complete tableau systems for the different versions of PMLN. These systems enable us to present some decidability methods. It yields “strong decidability” in the following sense: for every inference starting with a finite set of premises (resp. every syllogism, every formula) we can specify a finite number of steps to check whether it is logically valid. This method gives the upper bound of the cardinality of models needed for the examination of the validity of a given inference (resp. syllogism, formula).     

What do I gain from joining crowds? Does self‐expansion help to explain the relationship between identity fusion,group efficacy and collective action?

Four studies were carried out to examine how identity fusion, self‐ and group efficacy, and collective action are related and what role self‐expansion plays in these relationships. In the pilot study, participants recalled their experience of participating in mass gatherings. The three other studies were conducted during mass gatherings organized for collective purposes: a music concert (Study 1), a bicycle activist event (Study 2), and Equality Days (Study 3). The results showed (a) a significant positive relationship between personal and group identity fusion, self‐expansion, and self‐efficacy (Study 1); (b) a significant mediating effect of self‐expansion on the relationship between personal and group identity fusion and group efficacy (Studies 1 and 2); and (c) a significant mediating effect of self‐ expansion and group efficacy on the relationship between identity fusion and collective action tendency (Studies 2 and 3).     

Intention inertia and the plasticity of planning

In this article, I examine Michael Bratman’s account of stability in his planning theory of intention (PTI). Future-directed intentions should be stable, or appropriately resistant to change, over time. Bratman claims that the norm of stability governs both intentions and plans. The aim of this article is to critically enrich Bratman’s account of stability by introducing plasticity as an additional norm of planning. I construct plasticity as a kind of stability of intentions which supplements Bratman’s notion of “reasonable stability.” Unlike the latter, plasticity applies mainly to cases in which plan states are abandoned without reconsideration. I focus on the intra-theoretical problems of PTI and elucidate: (1) the distinction between future-directed intentions and plans, (2) the conceptual difference between stability and inertia, which is only implicit in PTI, and (3) the role of the environment of the planner, which has a vestigial role in Bratman’s work. I also defend my incorporation of plasticity against one possible objection and support it in the context of Bratman’s later works. Although critical, my proposal is in moderate harmony with PTI.     

Positive Time: Balanced Time Perspective and Positive Orientation

The aim of the research presented in this article is to investigate the relationship between positive orientation and time perspective as outlined by Zimbardo and Boyd (J Pers Soc Psychol 77:1271–1288, 1999) and extended by an additional form of concentration on the present. The Polish version of the Zimbardo Time Perspective Inventory was used. A third type of present time perspective, namely active concentration on the present, was measured by the Carpe Diem Scale. One hundred and eighty five Polish people (non-students) participated in a survey to which a canonical-correlation analysis and a cluster analysis were applied. Positive orientation was correlated with a balanced temporal profile comprising a strong positive past orientation, moderate concentration on the future, poor fatalistic time perspective, poor concentration on the negative past and moderate active concentration on the present. Whereas a positive orientation is based on a general positive attitude towards life and self, a balanced time perspective reflects a general positive attitude towards time, in which an active concentration on the present plays an important role.     

Counterfactuals and Historical Possibility

We show that truth conditions for counterfactuals need not always be given in terms of a vague notion of similarity. To this end, we single out the important class of historical counterfactuals and give formally rigorous truth conditions for these counterfactuals, employing a partial ordering relation called “comparative closeness” that is defined in the framework of branching space-times. Among other applications, we provide a detailed analysis of counterfactuals uttered in the context of lost bets. In an appendix we compare our theory with the branching space-times based reading of counterfactuals recently proposed by Belnap.     

The Tense Logic for Master Argument in Prior’s Reconstruction

In this paper we examine Prior’s reconstruction of Master Argument [4] in some modal-tense logic. This logic consists of a purely tense part and Diodorean definitions of modal alethic operators. Next we study this tense logic in the pure tense language. It is the logic K _t 4 plus a new axiom (P): ‘p Λ G p ⊃ P G p’. This formula was used by Prior in his original analysis of Master Argument. (P) is usually added as an extra axiom to an axiomatization of the logic of linear time. In that case the set of moments is a total order and must be left-discrete without the least moment. However, the logic of Master Argument does not require linear time. We show what properties of the set of moments are exactly forced by (P) in the reconstruction of Prior. We make also some philosophical remarks on the analyzed reconstruction. Presented by Jacek Malinowski     

On infinite EPR-like correlations

The paper investigates, in the framework of branching space–times, whether an infinite EPR-like correlation which does not involve finite EPR-like correlations is possible. The authors read earlier versions of this paper at the seminar ‘Chaos and Quantum Information’ at the Jagiellonian University in Kraków on April 16, 2007 and at the seminar ‘On Determinism’ at the University of Bonn on April 20, 2007.     

On quantum entanglement,counterfactuals, causality and dispositions

The existence of non-local correlations between outcomes of measurements in quantum entangled systems strongly suggests that we are dealing with some form of causation here. An assessment of this conjecture in the context of the collapse interpretation of quantum mechanics is the primary goal of this paper. Following the counterfactual approach to causation, I argue that the details of the underlying causal mechanism which could explain the non-local correlations in entangled states strongly depend on the adopted semantics for counterfactuals. Several relativistically-invariant interpretations of spatiotemporal counterfactual conditionals are discussed, and the corresponding causal stories describing interactions between parts of an entangled system are evaluated. It is observed that the most controversial feature of the postulated causal connections is not so much their non-local character as a peculiar type of circularity that affects them.
