Effects of domain-specific knowledge on memory for serial order

Knowledge concerning domain-specific regularities in sequential structure has long been known to affect recall for serial order. However, very little work has been done toward specifying the exact role such knowledge plays. The present article proposes a theory of serial recall in structured domains, based on Bayesian decision theory and a set of representational assumptions proceeding from recent computational and neurophysiologic research. The theory suggests that the accuracy with which a target sequence will be recalled is influenced by two interacting factors: (1) the 'goodness' of the sequence, i.e. its fit with the sequencing constraints that characterize its source domain, and (2) the sequence's neighborhood relations, i.e. the degree to which it resembles other sequences in the source domain. A specific prediction of the theory is that recall will be relatively poor for target lists with high-goodness near neighbors (the good neighbor effect). This prediction was tested and confirmed in an experiment evaluating recall for sequences based on an artificial grammar.     

What's measured is not necessarily managed: cognitive contingencies of organizational measurement

Organizational measurement is necessary for managing incremental improvements or change efforts. Some have argued that indicators of financial performance measure the past and should be joined by "lead" measures such as management development and customer relations, assumed to be drivers of performance. Approaches of "lead" measures have met criticism for not contributing to operational management. The present is an empirical case study where measures from a customer satisfaction survey and a management assessment instrument were analyzed and compared to actual measures of financial performance. The effects of measures obtained seem to depend on the interpretations and reflection taking place in the organization. The pursuit of "lead" indicators did not seem to drive results. Counter-intuitively, higher scores on these measures were related to poorer financial performance. The explication of and reflection on the underlying dynamic seemed to turn the development in a profitable direction.     

The growing complexity of international policy in intellectual property

Intellectual property has historically been a self-contained policy at the international level. With the introduction of the TRIPs Agreement in 1994 and developments since the conclusion of the TRIPs Agreement, the relationship between intellectual property policy and other areas of public policy has become much more complex and interactive. This shift reflects the centrality of intellectual property in the knowledge economy, the rapid development of enabling technologies, notably the Internet and biotechnology, and the advent of the networked society. The consequences of this shift are manifold and herald the increased sophistication and complexity that may be expected of intellectual property regimes in the knowledge economy. An earlier version of this paper was presented at an international conference, “The Ethics of Intellectual Property Rights and Patents,” held in Warsaw, Poland on 23–24 April, 2004.     

Liberalism and the Privatised Family: The Legacy of Rousseau

This article argues that the intellectual legacy of Rousseau is at the root of the failure of 20th century egalitarian theorists such as Rawls and Dworkin to engage intellectually with feminist theorists working within the liberal tradition. Through an extended critique of Rousseau’s delineation of the relationship between liberal citizenship and the private family, it argues that the failure of such liberal theorists to take gender hierarchy seriously is a consequence of their attempt to place the private family outside the sphere not only of politics, but also of justice.     

Partial Knowledge of Word Meanings: Thematic and Taxonomic Representations

The type of information (taxonomic or thematic) available at different levels of knowledge was investigated. Following extensive norming to identify taxonomic and thematic associates of low-frequency nouns, participants determined if taxonomic or thematic associates were meaningfully related to target words at three levels of knowledge: target words they correctly defined (known), recognized as familiar (frontier), or mistakenly denied as part of the language (unknown). In another experiment, participants reported which type of relationship (taxonomic or thematic) was preferred. Results indicated that both types of information were available at all levels of knowledge. However, accuracy and preference were greater for taxonomic associates across word levels. A differential increase in available thematic information relative to taxonomic information was found. Implications for the acquisition and representation of word meanings are discussed.     

Strategy choices in simple and complex addition: Contributions of working memory and counting knowledge for children with mathematical disability

Groups of first-grade (mean age = 82 months), third-grade (mean age = 107 months), and fifth-grade (mean age = 131 months) children with a learning disability in mathematics (MD, n = 58) and their normally achieving peers (n = 91) were administered tasks that assessed their knowledge of counting principles, working memory, and the strategies used to solve simple (4+3) and complex (16+8) addition problems. In all grades, the children with MD showed a working memory deficit, and in first grade, the children with MD used less sophisticated strategies and committed more errors while solving simple and complex addition problems. The group differences in strategy usage and accuracy were related, in part, to the group difference in working memory and to group and individual differences in counting knowledge. Across grade-level and group, the switch from simple to complex addition problems resulted in a shift in the mix of problem-solving strategies. Individual differences in the strategy mix and in the strategy shift were related, in part, to individual differences in working memory capacity and counting knowledge.     

Use of newsletters to promote environmental political action: an experimental analysis

The managers of beach businesses were randomly assigned to receive no intervention or two newsletters per week for 6 weeks that presented economic consequences of damage to coastal water quality and how to contact politicians. The percentage of proenvironmental political contacts was significantly greater in the experimental (newsletter) group than in the control group. Logistical regression showed that contacts in the newsletter group were more than five times that of controls after adjusting for history of contacts and predisposition to take such action. Results suggest that the intervention can promote political action that could influence environmental policies and human health.     

Interactions between Knowledge,Action and Commitment within Agent Dynamic Logic

This paper considers a new class of agent dynamic logics which provide a formal means of specifying and reasoning about the agents activities and informational, motivational and practical aspects of the behaviour of the agents. We present a Hilbert-style deductive system for a basic agent dynamic logic and consider a number of extensions of this logic with axiom schemata formalising interactions between knowledge and commitment (expressing an agent s awareness of her commitments), and interactions between knowledge and actions (expressing no learning and persistence of knowledge after actions). The deductive systems are proved sound and complete with respect to a Kripke-style semantics. Each of the considered logics is shown to have the small model property and therefore decidable.Presented by Ewa Orlowska     

Emancipatory responses to oppression: the template of land-use planning and the Old Order Amish of Ontario

In this paper I discuss the clash of values between the Old Order Amish community of Ontario and the dominant social paradigm in agriculture. Land-use and agricultural regulations, designed for an industrial style of agriculture, are experienced as a threat to the survival of the Old Order Amish agricultural social economy and community. The paper describes how I have worked with the Old Order Amish to respond to these challenges and to create public policies that will allow them to maintain their human and agricultural diversity and small-scale sustainable farm practices. Four case studies illuminating the oppressive land-use regulations along with the emancipatory responses to the oppression are examined. The social transformation themes include principles and processes for community psychologists, land-use planners, and community economic development practitioners to consider. The article has heuristic value for a practice-based approach to social change.
