Innovation and Organizational Learning: the Case of Computer-Aided Production Management

Recent experience of unsuccessful implementation of integrated advanced manufacturing technology suggests that much of the problem is due to a lack of innovation in organizational in parallel with the technological dimension. Discussion of this issue argues the need for some kind of ‘organizational learning’ to obtain the full benefits of AMT. This paper reviews the topic of organizational learning in technology and explores its relevance to the problem of AMT implementation through the case example of computer-aided production management systems.     

Modelling stochastic volatility using generalized t distribution

In modelling financial return time series and time-varying volatility, the Gaussian and the Student-t distributions are widely used in stochastic volatility (SV) models. However, other distributions such as the Laplace distribution and generalized error distribution (GED) are also common in SV modelling. Therefore, this paper proposes the use of the generalized t (GT) distribution whose special cases are the Gaussian distribution, Student-t distribution, Laplace distribution and GED. Since the GT distribution is a member of the scale mixture of uniform (SMU) family of distribution, we handle the GT distribution via its SMU representation. We show this SMU form can substantially simplify the Gibbs sampler for Bayesian simulation-based computation and can provide a mean of identifying outliers. In an empirical study, we adopt a GT–SV model to fit the daily return of the exchange rate of Australian dollar to three other currencies and use the exchange rate to US dollar as a covariate. Model implementation relies on Bayesian Markov chain Monte Carlo algorithms using the WinBUGS package.     

Adults in Wilderness Treatment: A Unique Application of Attachment Theory and Research

Research shows how an understanding of adult attachment applies to clinical treatment, such as outpatient therapy, but no literature explores the application of adult attachment to wilderness therapy, a distinct type of residential treatment. This paper explores how an understanding of adult attachment applies to wilderness therapy clients, as the nature of wilderness therapy involves losses, separations, and reunions, all of which evoke attachment needs. Adult wilderness treatment exemplifies an effective method of treatment that provides a secure base and supports healthy attachment relationships.     

Work-related reproductive health: a review

This paper reviews the literature concerning the impact of work on reproductive health. In doing so, it offers a framework model for guiding future research and practice. Contemporary models of occupational health usually identify at least two pathways linking exposure to workplace hazards to their effects on health. The study of work-related reproductive health has been largely restricted to the effects of the more tangible and physical hazards of work mediated by a largely physico-chemical pathway. However, the growth of research into the psycho-physiological influence of stress on reproductive health provides a new direction for research in this domain with the exploration of a complementary pathway. The extension of this new approach into the investigation of the effects of work design and management on reproductive health represents a potentially important and further development.     

The effects of transformational leadership on followers' perceived work characteristics and psychological well-being: A longitudinal study

Transformational leaders employ a visionary and creative style of leadership that inspires employees to broaden their interest in their work and to be innovative and creative. There is some evidence that transformational leadership style is linked to employee psychological well-being. However, it is not clear whether this is due to (1) a direct relationship between leadership behaviour and affective well-being outcomes, or (2) a relationship between leadership behaviour and well-being that is mediated by followers' perceived work characteristics. (Such characteristics include role clarity, meaningfulness, and opportunities for development.) This study aims to extend previous work by examining the validity of these two mechanisms in a longitudinal questionnaire study. The study was carried out within the elderly care sector in a Danish local governmental department. A theory-driven model of the relationships between leadership, work characteristics, and psychological well-being was tested using Structural Equation Modelling. The results indicated that followers' perceptions of their work characteristics did mediate the relationship between transformational leadership style and psychological well-being. However, there was only limited evidence of the existence of a direct path between leadership behaviour and employee well-being. These findings have implications for design, implementation, and management of efforts to improve employee well-being.     

A NEW MEASURE OF ROTATABILITY OF RESPONSE SURFACE DESIGNS

This paper proposes a new measure of rotatability of a response surface design. It is based on a comparison between the design moments of a given design and the design moments of a rotatable design closest to the given design in the least squares sense. This measure is easier to calculate than Khur?s measure. An alternative easier non-geometrical way of deriving Khuri's measure is also presented. Both measures are calculated to illustrate some designs considered by Khuri.     

Projector operators in the multivariate Zyskind-Martin model

Summary Two quadratic formsS _H andS _E for a testable hypothesis and for an error in the multivariate Zyskind-Martin model with singular covariance matrix are expressed by means of projector operators. Thus the results for the multivariate standard model with identity covariance matrix given by Humak (1977) and Christensen (1987, 1991) are generalized for the case of Zyskind-Martin model. Special cases of our results are formulae forS _H andS _E in Aitken's (1935) model. In the case of general Gauss-Markoff modelS _H andS _E can also be expressed by means of projector operators for some subclasses of testable hypotheses. For these hypotheses, testing in Gauss-Markoff model is equivalent to testing in a Zyskind-Martin model.     

Re-Eroticizing the Organization: An Exegesis and Critique

This paper examines an important recent development in thinking on the role of sexuality and eroticism within organizations, namely Re-eroticization theory. The paper contextualizes this development by contrasting it with modemist-masculinist and modernist-feminist discourses on eroticism and organizations prior to synthesizing the many disparate strands of Re-eroticization theory. Re-eroticization is then examined critically in terms of its theoretical assumptions and the nature of its emancipatory promise. In particular, it is argued that Re-eroticization theory retains an unacknowledged essentialism which renders its emancipatory claims problematic, and is overly sanguine with respect to violent forms of eroticism.
