Models of Cognition,the Contextualisation of Knowledge and Organisational Theory

This paper examines the importance of cognitivefoundations for theories of organisationalbehaviour. Three different conceptions of humancognition and reasoning are examined: theinformation processing, situated learning andcultural-historical perspectives. The papershows how each conception of cognition leads toa different understanding of organisationalroutines and organisational problem-solving, aswell as to the adoption of a differentempirical methodology for observingorganisational behaviour and for testinghypotheses about the nature of routines andproblem-solving. The paper demonstrates that ofthe three approaches to human cognition, onlythe cultural-historical one gives rise to anunderstanding of organisational knowledge asembedded within a wider cultural andinstitutional setting.

Following the herd is easy when it comes to business ventures. But if you really want to start something new, you must first carefully think it through. Learn some ways to do that before you set out on a new path.     

BAYESIAN SUBSET SELECTION AND MODEL AVERAGING USING A CENTRED AND DISPERSED PRIOR FOR THE ERROR VARIANCE

This article proposes a new data‐based prior distribution for the error variance in a Gaussian linear regression model, when the model is used for Bayesian variable selection and model averaging. For a given subset of variables in the model, this prior has a mode that is an unbiased estimator of the error variance but is suitably dispersed to make it uninformative relative to the marginal likelihood. The advantage of this empirical Bayes prior for the error variance is that it is centred and dispersed sensibly and avoids the arbitrary specification of hyperparameters. The performance of the new prior is compared to that of a prior proposed previously in the literature using several simulated examples and two loss functions. For each example our paper also reports results for the model that orthogonalizes the predictor variables before performing subset selection. A real example is also investigated. The empirical results suggest that for both the simulated and real data, the performance of the estimators based on the prior proposed in our article compares favourably with that of a prior used previously in the literature.     

Palliative and curative care nurses' attitudes toward dying and death in the hospital setting

This paper explores the errors involved in the approximation of both the maximum and sum of two independent Beta random variables, each by another Beta random variable. The principal area of application is the time analysis of PERT networks, and the results are interpreted and discussed in terms of this application. The error was found to be acceptable for the greater part of the range of the parameters involved. The results will help practitioners estimate the mean and standard deviation of the completion time of PERT networks.     

Is Managed Mental Health Treatment Psychotherapy?

The corporate takeover of mental health treatment has dramatically affected mental health treatment. Two essential constituents of psychotherapeutic process, the relationship between patient and therapist and the special communicative process associated with a talking treatment, have been significantly compromised. Therapists and patients are being forced to consider whether in the absence of confidentiality, self determination, and a secure treatment partnership managed mental health care can be called psychotherapy. Drawing on several detailed sessions from the managed treatment of a young woman, the writer concludes that the answer is no.     

Statistical and Historical Analyses of Nations Which Deviate From the Size-Density Law

We examine nations which deviate significantly from the ?2/3 sizedensity slope previously observed for the aggregated political subdivisions of 98 modern nations and previously derived from the theory of timeminimization. We correct Stephan’s original list of deviant nations, demonstrate that all slopes more negative than ?2/3 were due to the erroneous inclusion of cities in the original data sets, develop a theory to account for the less negative deviant slopes, and test the theory both through statistical manipulation of current data and through analysis of available historical data.     

Perceived importance of “social goals” in business organizations

Business organizations operate within a complex socio-technical environment. Interactions between these socio-technical dimensions and the managers' personal value systems are thought to influence managerial role patterns and decisions. This paper investigates shifts in perceived importance of “social goals” from a set of organizational goals. The research concludes that there has been no significant changes occurring in either the ordering or the clustering of organizational goals.
