A brief history of negation

The history of scholarship on negation tracks and illuminates the major developments in the history of metaphysics, philosophy of language, and philosophy of mind, from Parmenides, Plato and Aristotle through Frege, Russell, and Wittgenstein to contemporary formal theorists. Our perspective focuses on the catalytic role played by the 20th century philosopher of language Paul Grice, whose views on negation serve as a fulcrum for his attempt to bridge the (neo-)Traditionalist and Formalist traditions in logical thought. Grice's remarks on negation and speaker meaning and the elaboration of his ideas by subsequent neo-Griceans are summarized and situated within a broader picture of the role of contradictory and contrary negation in the frameworks of Aristotelians, Medievals, early modern schoolmaster-logicians, 19th and early 20th century neo-Idealists and Formalists, Oxford ordinary-language analytics, practitioners of classical and non-classical logics, and a range of other philosophers and linguists. Particular attention is paid to the relations between negation and the other operators of propositional and predicate calculus. Implications for accounts of the semantics and pragmatics of natural language are also pursued and extensive references to related work are provided.     

Developmental change in young children's use of haptic information in a visual task: the role of hand movements

Preschoolers who explore objects haptically often fail to recognize those objects in subsequent visual tests. This suggests that children may represent qualitatively different information in vision and haptics and/or that children’s haptic perception may be poor. In this study, 72 children (2½-5 years of age) and 20 adults explored unfamiliar objects either haptically or visually and then chose a visual match from among three test objects, each matching the exemplar on one perceptual dimension. All age groups chose shape-based matches after visual exploration. Both 5-year-olds and adults also chose shape-based matches after haptic exploration, but younger children did not match consistently in this condition. Certain hand movements performed by children during haptic exploration reliably predicted shape-based matches but occurred at very low frequencies. Thus, younger children’s difficulties with haptic-to-visual information transfer appeared to stem from their failure to use their hands to obtain reliable haptic information about objects.     

Work Motivation in “Post-Socialist” Industrial Organizations

Abstract

This article describes a study into the needs and behavioural reaction patterns in a sample of 715 workers in Bulgarian industrial firms during the “post-Socialist” period. The findings from this study cast doubt on some popular views of the typical motivation and reactions to work in the former “Socialist society”. Our data suggest that higher order needs are dominant in the motivational hierarchy and are significant in determining work outcomes, such as satisfaction, tendency to leave, and stress. We found no evidence for a motivational stereotype characterized by a low level of work involvement, lack of initiative, obedience, etc. hypothesized by other authors. In order to gain a better understanding of work motivation, it is useful to differentiate needs from the opportunities to satisfy those same needs, as well as work motivation from behavioural reaction patterns that actualize the opportunities and relate them to personal outcomes. A specific behavioural reaction pattern seems to exist among Bulgarian workers as an adaptation reaction to the specific environment of the “(post-) Socialist” industrial organization. This pattern, identified as “egocentrism in work”, combines a high involvement in work with partial alienation, i.e. detachment from the organization and income.     

Anticipation and Source-Monitoring Errors: Children's Memory for Collaborative Activities

When asked to remember who contributed what to the completion of shared, goal-directed activities, children exhibit a bias to over-attribute contributions to themselves, recoding partners' actions as their own. The goals of the 3 experiments reported here were to explore task characteristics that might influence these recoding processes, and as a result, reveal more about them. The timing of the child's contributions in relation to the partner's actions was found to be crucial for recoding (Experiments 1 and 3). The availability of a model outcome affects recoding as well (Experiment 2), but appears not to be a prerequisite. In the absence of a physical outcome, recoding is still observed (Experiment 3). Anticipation of the partner's actions appears to account for all of these effects. Findings have implications for understanding children's source monitoring abilities as well as for understanding internalization processes thought to support collaborative learning.     

Levels of analysis and sources of data in sales research: a multilevel-multisource review

Sales researchers are increasingly adopting a multilevel-multisource (MLMS) approach to answer many key questions involving sales managers, salespeople and customers. MLMS research involves the acquisition and analysis of data collected from two or more sources pertaining to multiple hierarchical levels and presents a number of opportunities and challenges for sales researchers to consider. The authors highlight the benefits and the drawbacks of MLMS research and describe various approaches for implementing an MLMS collection and analysis. Additionally, a review of the MLMS studies conducted in the sales domain is provided which summarizes and delineates relationships tested in the extant literature. Based on this review, the authors advance a number of underdeveloped areas of research where MLMS approaches can be applied to further the understanding of the dynamic conditions that typify sales research.
