It is shown that in a linearly ordered MV-algebra A , the implication is unique if and only if the identity function is the unique De Morgan automorphism on A . Modulo categorical equivalence, our uniqueness criterion recalls Ohkuma's rigidness condition for totally ordered abelian groups. We also show that, if A is an Archimedean totally ordered MV-algebra, then each non-trivial De Morgan automorphism of the underlying involutive lattice of A yields a new implication on A , which is not (...) isomorphic to the original implication.

This article provides the foundation for a new predictive theory of animal learning that is based upon a simple logical model. The knowledge of experimental subjects at a given time is described using logical equations. These logical equations are then used to predict a subject’s response when presented with a known or a previously unknown situation. This new theory suc- cessfully anticipates phenomena that existing theories predict, as well as phenomena that they cannot. It provides a theoretical account for phenomena (...) that are beyond the domain of existing models, such as extinction and the detection of novelty, from which “external inhibition” can be explained. Examples of the methods applied to make predictions are given using previously published results. The present theory proposes a new way to envision the minimal functions of the nervous system, and provides possible new insights into the way that brains ultimately create and use knowledge about the world.

Beckers et al. (2006) published intriguing results, obtained in the rat fear condi- tioning paradigm, challenging classical associativist theories of learning. One of the main findings of Beckers et al. (2006) is that what they called subad- ditive pretraining abolished the expres- sion of blocking. Haselgrove (2010) proposed an expla- nation, based on the well known Rescorla- Wagner Model (Rescorla and Wagner, 1972). We will demonstrate here that the account offered by Haselgrove (2010) is contradictory to the basic assumptions of (...) the Rescorla-Wagner Model. (shrink)
Interest in republicanism as a political theory has burgeoned in recent years, but its implications for the understanding of law have remained largely unexplored. Legal Republicanism is the first book to offer a comprehensive, critical survey of the potential for creating republican accounts of fundamental issues in law and legal theory.
College cheating is prevalent, with rates ranging widely from 9 to 95% (Whitley, 1998). Research has been exclusively conducted with enrolled college students. This study examined the prevalence of cheating in a sample of college alumni, who risk less in disclosing academic dishonesty than current students. A total of 273 alumni reported on their prevalence and perceived severity of 19 cheating behaviors. The vast majority of participants (81.7%) report having engaged in some form of cheating during their undergraduate career. The (...) most common forms of cheating were “copying from another student's assignment” and “allowing others to copy from your assignment.” More students reported cheating in classes for their major than other classes. Males and females cheated at the same rates in classes for their major, and males reported higher rates of cheating than females in nonmajor classes. Respondents reported that their top reasons for cheating were “lack of time” and “to help a friend.”. (shrink)
Over the past decade, sequence learning has gradually become a central paradigm through which to study implicit learning. In this chapter, we start by briefly summarizing the results obtained with different variants of the sequence learning paradigm. We distinguish three subparadigms in terms of whether the stimulus material is generated either by following a fixed and repeating sequence (e.g., Nissen & Bullemer, 1987), by relying on a complex set of rules from which one can produce several alternative deterministic sequences (e.g., (...) Lewicki, Hill & Bizot, 1988; Stadler, 1989), or by following the output of a probabilistic set of rules such as instantiated by noisy finite-state grammars (Cleeremans & McClelland, 1991; Jiménez, Mendéz & Cleeremans, 1996). Next, we focus on the processes involved in sequence representation and acquisition. We suggest that the sensitivity to the sequential structure observed in the probabilistic subparadigm can only be a result of the acquisition of a representation of the statistical constraints of the material, and that this sensitivity emerges through the operation of mechanisms that are well instantiated by connectionist models such as the Simple Recurrent Network (Elman, 1990; Cleeremans, 1993b). We present new simulation work meant to explore to what extent the model can also account for specific data obtained in a paradigmatic instance of deterministic, rule-based sequence learning task: Lewicki et al. (1988)'s situation. Finally, we report on the results of an experiment that compares learning on otherwise similar deterministic and probabilistic structures, and we show that learning of both types of structures is equivalent only under conditions that maximally hinder explicit acquisition. Taken together, these simulation and experimental data lend support to the claim that implicit learning in all three sequence learning subparadigms can amount to a form of statistical sequence learning. They also suggest that distinguishing among several theories of sequence representation and acquisition may require us to analize the data in great detail. Hopefully, however, some truth can be found in such details.. (shrink)
This study examines Wal-Mart representatives' presentation to the community on their site plan and Draft Environmental Impact Statement. Given the ongoing controversy and criticisms from local residents, it is interesting to see Wal-Mart's strategies in attenuating these risks and negative impacts. The discursive practices found here are: formulating prior citizen complaints by a neutral-sounding, legalistic language which works euphemistically or as a gloss. Citizen concerns are fitted into a problem-solution format where the solutions involve engineering technology. The Wal-Mart representatives display (...) their expertise through describing these technological answers. Scientific documents or tests are presented which point to counter-intuitive results. They draw on a discourse of `facts' and `information', but use these to make arguments in support of their proposals. In addition to displaying scientific-technological expertise, they avow openness to dialogue and willingness to work with the town. The Wal-Mart representatives present themselves as both technical experts and trustworthy partners, but they also may be seen as rhetor in using facts, findings, and documents to make an argument for their project.

The scientific understanding of cognition and consciousness is currently hampered by the lack of rigorous and universally accepted definitions that permit comparative studies. This paper proposes new functional and un- ambiguous definitions for cognition and consciousness in order to provide clearly defined boundaries within which general theories of cognition and consciousness may be developed. The proposed definitions are built upon the construction and manipulation of reality representation, decision making and learning and are scoped in terms of an underlying logical structure. (...) It is argued that the presentation of reality also necessitates the concept of ab- sence and the capacity to perform transitive inference. Explicit predictions relating to these new definitions, along with possible ways to test them, are also described and discussed. (shrink)

This essay explores the relationships between labour and community formation in order to think through how, where, and when diasporic solidarities are imagined or refused. I draw on ethnographic research among Jamaican women contracted for seasonal work in US hotels to situate diasporic calls and responses in relation to specific contexts and a changing global political economy. I show how global geopolitical shifts not only shape the processes of identity formation and social reproduction, but also condition the perpetuation of notions (...) of nationalized racial hierarchies and ideologies of progress. I also show that hotel workers’ notions of ‘America’ and their commitment to the ‘American Dream’ shapes their subjectivities as migrant workers/consumers and, in their assessment, differentiates them from African-Americans, particularly those most immediately affected by Hurricane Katrina. In doing so, I demonstrate that one of the ideological hegemonies of diaspora is the idea that an individual's capacity to affect their own social mobility and that of their social network always outstrips the ‘locals’ in diasporic elsewheres.

This article discusses how the issue of precarity has developed into a new catalyst for activism in Italy and demonstrates how this activism is linked to changes in the employment and capitalist manufacturing environment of the 1980s and 1990s. It links events in Italy to the activism of the global anti-neoliberal movement and discusses how various activist movements, radical feminist activism) are mobilizing around the issue of precarity. This article focuses specifically on the activist network ‘Precari su Marte’ which has (...) been active in Turin since 2005. It demonstrates how the theoretical and practical evolution of this network has led to various outcomes, including experimenting with creative forms of political practice at MayDay demonstrations and questioning the boundaries of gender.

This paper explores the social, legal, and political issues Wal-Mart faces in each of the three North American countries and suggests reasons for the quite significant differences. It also issues a call to Business and Society scholars to add prescriptive work to the already large body of descriptive work that has been collected.
Schoolgirls writing short stories have surrendered themselves to some rules of a game, which, according to Ricoeur and Gadamer, delimits a field where everything ’is played’, and thereby, ’shatters the seriousness’ of ’the self-presence of a subject’. This article proposes that this field has a serious side of its own that reveals something true about the everyday reality of being a girl. The proposed worlds in the girls’ short stories are places from which research on women’s lives should begin is (...) a central argument, along with the contention that for the researcher to be able to take the seriousness of this playful writing into account, she also has to assume the position of a playful figure. The article suggests that the empirical data of schoolgirl writing invited the researcher to think Ricoeur and feminist epistemology together. Further, a suggestion is that the roles of reading given by the texts have consequences for a ’new’ process-oriented writing pedagogy and the teacher of writing as well. (shrink)
Abstract The role accorded to the public by scientists and philosophers of science has undergone an essential historical change in the last three centuries. Public participation in (witnessing of) scientific experiments was considered an important requirement for 17th century experimenters (e.g. for Boyle or Pascal). The cognitive role played by lay persons was later substantially downgraded; witnessing went out of fashion, while science became more and more esoteric and a matter for experts only. Part of this process was that all (...) scientific disciplines became intensively compartmentalized and in consequence a rather puzzling or even paradoxical situation appeared: that the scientists themselves were and are being reduced epistemically to the status of lay persons, outside of their proper field of expertise (as was pointed out by J. Hardwig). The paper deals with some cognitive aspects of this historical process. (shrink)
The case focuses on the decision by the Norwegian Ministry of Finance in 2006 to remove Wal-Mart Stores, Inc. from its investment portfolio because of theretailer's "serious and systematic" abuses of human and labor rights. Discussion of the decision-making process that led to the divestiture, and the impact that Wal-Mart has had on various realms – social, economic, industry, and the supply chain, among others – are included in the case.
