You said it before and you'll say it again: Expectations of consistency in communication.

Repeated reference creates strong expectations in addressees that a speaker will continue to use the same expression for the same object. The authors investigate the root reason for these expectations by comparing a cooperativeness-based account (Grice, 1975) with a simpler consistency-based account. In two eye-tracking experiments, the authors investigated the expectations underlying the effect of precedents on comprehension. The authors show that listeners expect speakers to be consistent in their use of expressions even when these expectations cannot be motivated by the assumption of cooperativeness. The authors conclude that though this phenomenon seems to be motivated by cooperativeness, listeners' expectation that speakers be consistent in their use of expressions is governed by a general expectation of consistency.

Knowledge transfer in IT offshoring relationships: the roles of social capital,efficacy and outcome expectations

Information technology (IT) development in global organisations relies heavily on the transfer of tacit and complex knowledge from onshore units to offshore subsidiaries. A central concern of such organisations is the development of social capital, which is known to facilitate the smooth transfer of knowledge. However, only a few studies in IS research have explicitly examined the role of social capital for knowledge transfer in an IT offshoring context. In this paper, we argue that such knowledge transfer mechanisms can be understood better by considering social capital in concert with knowledge senders' efficacy and outcome expectations, two of the potentially key motivational drivers of knowledge transfer. We develop our arguments through a qualitative case study of a large German multinational company. German IT developers in this firm provided in‐depth accounts of their experience with offshore colleagues in an Indian captive subsidiary unit. Drawing on our analysis, we develop a model that depicts the influence of social capital, efficacy and outcome expectations on onshore IT developers' ability and willingness to transfer knowledge to offshore colleagues. Through the model, we also explain how social capital, efficacy and outcome expectations are interrelated and generate three interlocked, self‐reinforcing circles of knowledge transfer success in IT offshoring relationships.     

Using Parallelization to Solve a Macroeconomic Model: A Parallel Parameterized Expectations Algorithm

Solving nonlinear macroeconomic models with rational expectations can be time-consuming. This paper shows how the parameterized expectations algorithm (PEA) can be parallelized to reduce the time needed to solve a simple model by more than 80%. The general idea of using parallelization applies naturally to other algorithms, as well. This paper is illustrative of the speedup that can be obtained, and it provides computer code that may serve as an example for parallelization of other algorithms. For those who would like to use the parallelized PEA, the implementation does not confront end users with the details of parallelization. To solve a model, it is only necessary to provide ordinary serial code that simulates data from the model. All needed code is available, on a standalone basis, or pre-installed on ParallelKnoppix (Creel, J Appl Economet 22:215–223, 2007).      

Nonlinear Versus Linear Learning Devices: A Procedural Perspective

We provide a discussion of bounded rationality learning behind traditional learning mechanisms, i.e., Recursive Ordinary Least Squares and Bayesian Learning . These mechanisms lack for many reasons a behavioral interpretation and, following the Simon criticism, they appear to be substantively rational. In this paper, analyzing the Cagan model, we explore two learning mechanisms which appear to be more plausible from a behavioral point of view and somehow procedurally rational: Least Mean Squares learning for linear models and Back Propagation for Artificial Neural Networks . The two algorithms look for a minimum of the variance of the error forecasting by means of a steepest descent gradient procedure. The analysis of the Cagan model shows an interesting result: non-convergence of learning to the Rational Expectations Equilibrium is not due to the restriction to linear learning devices; also Back Propagation learning for Artificial Neural Networks may fail to converge to the Rational Expectations Equilibrium of the model.     

The Information Literacy Challenge

Abstract

Technological changes are occurring rapidly. As one result, students entering college are bringing very disparate computer skills and attitudes. Some students are reluctant to embrace new technologies; others demand electronic resources for all assignments. By considering the computer access and Internet resources available to elementary school students today, we can only imagine what our users of tomorrow will expect from libraries. Although college students may arrive at our libraries with increased computer skills, their knowledge of electronic information may be lacking. Definitions of information literacy and an overview of information literacy skills are outlined. The Digital Information Literacy program at The University of Texas at Austin, as well as the technological environment and facilities at the institution, serve as a case study for integrating information literacy skills into traditional services and partnerships.     

Credit Constraints and Price Expectations of Homeowners

This paper examines the effect of credit constraints on the sale price expectations of homeowners. We extend the results of Genesove and Mayer (1997) by using a sample of mover and non-mover families living in the Netherlands—a country without formal down-payment requirements. We find that homeowners who are more credit constrained expect to sell their house for a higher price. Homeowners already seem to compensate for credit constraints at the very first stages of the transaction process. These results imply that the findings of Genesove and Mayer (1997) are much more generally applicable than previously considered.     

Vernacular architecture: questions of comfort and practicability

A paradoxical situation exists where vernacular building traditions are in a state of decline and are being replaced by modern counterparts, but they are repeatedly cited in the academic literature as exemplary models of environmental practice. This paradox is examined through research on whether vernacular passive cooling systems in the hot and dry climates of present-day Iran are practicable for the provision of comfortable indoor temperatures. Investigating their technical thermal performance as well as user perceptions and behaviour, positive and negative attributes of the cooling systems are identified. If conclusions about the long-term viability of vernacular buildings are to be drawn, then social, cultural, economic and environmental attributes need to be taken into consideration. Despite rather widespread and persistent assumptions, vernacular building traditions are not necessarily able to survive and the choices made by local people regarding the continuation or abandonment of specific traditions are influenced by a variety of cultural and practical factors. This substantiates the necessity of an integrated and holistic approach that engages with these variables in order to acquire a better understanding of the conditions for the survival of vernacular traditions.

Le fait que les traditions architecturales vernaculaires se trouvent dans un état de déclin et sont remplacées par leurs équivalents modernes, alors même qu'elles sont citées à maintes reprises dans la littérature universitaire comme des modèles exemplaires de pratique environnementale, constitue une situation paradoxale. Ce paradoxe est étudié au travers de recherches visant à déterminer si les systèmes de refroidissement passif vernaculaires sous les climats chauds et secs de l'Iran d'aujourd'hui peuvent être mis en pratique pour assurer des températures intérieures confortables. L’étude de leurs performances thermiques techniques aussi bien que des perceptions et du comportement des utilisateurs permet d'identifier les attributs positifs et négatifs des systèmes de refroidissement. S'il faut tirer des conclusions concernant la viabilité à long terme des bâtiments vernaculaires, il est alors nécessaire de prendre en considération les attributs sociaux, culturels, économiques et environnementaux. En dépit de présomptions plutôt répandues et tenaces, les traditions architecturales vernaculaires ne sont pas nécessairement capables de survivre et les choix opérés par les populations locales quant à la poursuite ou l'abandon de traditions spécifiques sont influencés par divers facteurs culturels et pratiques. Ceci confirme la nécessité d'une approche intégrée et holistique qui, par ces variables, incite à acquérir une meilleure compréhension des conditions propres à assurer la survie des traditions vernaculaires.

Crossmodal associations and subjective ratings of Asian noodles and the impact of the receptacle

We investigated the crossmodal associations that people hold for Asian noodles, and the influence of the plateware/receptacle. Chinese participants viewed online photographs of natural, red, green, and yellow noodles presented in bowls or plates made from ceramic, glass, paper, or stainless steel. In Experiment 1, the participants reported the first taste/flavour that came to mind, and rated their feelings and taste/flavour expectations concerning the noodles. In Experiment 2, the participants had to choose a taste term from a list to indicate the first taste that came to mind, and rated their feelings about the noodles. The results of both experiments revealed that the red noodles tended to be associated with a spicy taste/flavour; whereas the yellow noodles were often associated with a savoury taste/flavour, and rated as looking more familiar and pleasant than either the red or green noodles. The receptacles used to present the noodles did not influence the observed colour-flavour associations. However, the material of the receptacles appeared to interact with the colour of the noodles in terms of influencing people’s subjective ratings of, and taste/flavour expectations concerning, the noodles. These findings therefore demonstrate the complex interactions that can occur between the colour of the product and the type/material of the receptacle on people’s expectations regarding the taste/flavour of Asian noodles in the Asian marketplace.     

On the evaluation of Six Sigma projects

Most of the research on the success in implementing Six Sigma agrees upon the fact that one of the key success factors is the selection of profitable projects. This seems to be especially important for high‐risk, large‐scope and long‐term projects, as is mostly the case in the design for Six Sigma projects. The purpose of this paper is to outline Six Sigma project characteristics and to present a new model for evaluating Six Sigma projects. To design a Six Sigma project evaluation model, we utilized mathematical optimization modeling techniques and real options theory. The model allows for the quantification of not only the project's value prior to its start but also its progress and the consideration of possible decisions based on this progress.
