Innovation theories in retrospect : the case of electronic commerce adoption in small business in New Zealand

A review of the technological innovation adoption literature on small to medium-sized enterprises (SMEs) provides useful insights into factors influencing innovation adoption but points to the need to introduce more determinants of innovation adoption to SMEs research. This research is interested in identifying these factors and hence, introducing more potential determinants to electronic commerce (EC) adoption research in SMEs. Therefore, this research attempts to extend the technological innovation theories to EC adoption research in SMEs by identifying potential constructs and factors from these theories and then checking their face validity using three case studies in New Zealand. This research endeavours to shortlist and discuss the most important determinants of EC adoption and to eliminate the least relevant ones.

Generalized pseudo-likelihood estimates for markov random fields on lattice

In this paper we generalize Besag's pseudo-likelihood function for spatial statistical models on a region of a lattice. The correspondingly defined maximum generalized pseudo-likelihood estimates (MGPLEs) are natural extensions of Besag's maximum pseudo-likelihood estimate (MPLE). The MGPLEs connect the MPLE and the maximum likelihood estimate. We carry out experimental calculations of the MGPLEs for spatial processes on the lattice. These simulation results clearly show better performances of the MGPLEs than the MPLE, and the performances of differently defined MGPLEs are compared. These are also illustrated by the application to two real data sets.

A review of employment relations theories and their application

New developments in the industrial relations and human resource management have moved management and employee bargaining down to the level of the firm. In doing so they have generated a growing level of interest in the conduct of employment relations, not just at the level of specialist managers, who have traditionally had the responsibility for dealing with issues in this area, but across management as a whole. There is thus a growing need for managers to place more emphasis on achieving a greater symmetry between commercial objectives and employment practices. This paper looks at the predicates of managerial authority and its legitimacy, and how personal assumptions and value systems (i.e., ‘frames of reference’) held by managers can predispose them to view the nature of work and workplace relations in particular ways. The paper also presents
and aligns a range of contemporary theories within the province of such systems, with the aim being to show how judgements made about the worth or otherwise of a given range of theories are inevitably shaped by the type of value system and set of assumptions one holds towards the
world of work. The paper concludes by offering a practical guide to managers on how to evaluate their own assumptions and value systems when applying the noted theories and concepts to real world circumstances. In doing so, the paper provides a tool kit of theories and concepts that should allow managers to avoid engaging in workforce management practices that are either illconceived or based on intuitive premises.

Should we save or should we consume? Linking growth theories and the Keynesian models

In major economic growth theories, high saving rate gives rise to high level of output per capita. But in Keynesian economics, high saving rate causes low consumption and will lead the economy into recession. Students may ask, "For the well-being of an economy, should we save or should we consume?" In most of the intermediate macroeconomics textbooks, economic growth and Keynesian economics are taught in separate chapters; and in many cases, these chapters are not even successive to each other. There lacks a continuity between the long run and short run models. This paper builds a bridge between growth theories and Keynesian models. It links the Solow diagram and the IS-LM curves and depicts the short run and long run implications of a change in the saving rate.

Predicting consumer innovative behavior using alternative theories and likelihood measures: a longitudinal study

This paper reports on a longitudinal study of consumers, where two dominant theories that purport to predict innovative behavior are applied and compared directly, using a methodology suggested as ideal by past researchers. Predictions made prior to launch were then evaluated against multiple measures of purchase likelihood, and against actual adoption behavior up to 12 months after launch. The results of this study suggest that perceptions of the innovations characteristics (PIC) predicted the selfreported likelihood of adoption better than the Domain Specific Innovativeness (DSI) scale, a personality-based measure. Prediction of actual adoption was largely inaccurate and both theories massively over predicted adoption levels, however the DSI scale was slightly more accurate. The conclusions here are that no one theory could make adequate predictions of behavior, that purchase likelihood measures are a poor substitute for measuring actual behavior but that purchase probability scales should be used more often in adoption research.

Applications of cognitive theories to children's fire safety education

Children under five have the highest rate of fire-related accidents (Australian Institute of Health and Welfare, 2001). It is therefore essential to develop effective fire safety education programs to prevent casualties due to a fire. At present, there are fire education programs conducted across Australia for primary school children. However, it is vital that these programs get their message across to the children in the most efficient manner to help children retain the information. The present study evaluated the effectiveness of the 'Fire Ed' program conducted in Victoria and assessed the retention of fire safety information in children in preparatory and Grade five levels. The findings suggest that the information is not retained over long periods of time. Suggestions are made to provide fire safety education in line with
theories of cognitive development to make it more effective.

Integrating job stress and social exchange theories to predict employee wellbeing

This research examines the organizational characteristics that contribute to employee wellbeing in public sector agencies that have undergone substantial organizational change. Two studies were undertaken, the first involving 2,466 police officers working in a statebased law enforcement agency, whereas the second comprised 1,010 occupationally diverse employees working in a State Government authority. The research was guided by a theoretical framework that begins with a model underpinning many large-scale job stress investigations—the job strain model (JSM)—and is expanded to incorporate widely used social exchange variables (i.e., psychological contract breach and organizational fairness). The results of hierarchical regression analyses from both studies confirm the value of the JSM. There was also strong support for extending the JSM to include the breach and fairness variables; however, proposed interactions between job demands and organizational fairness failed to add to the explanatory value of the model. The implications of these results particularly for public sector organizations that have undergone extensive reforms consistent with New Public Management are discussed.

Using job strain and psychological contract theories to predict employee wellbeing in a reformed public sector agency

This study investigates the Issues that contribute to employee wellbeing in a public sector agency having undergone substantial reform The research is based on a model that is initially demand-oriented, and is expanded to incorporate psychological contract breach and organisational justice. Hierarchical regression analyses were conducted on the 1,010 completed surveys The results confirm the value of the Job strain model (JSM) and that the inclusion of breach and fairness were worthwhile extensions of the JSM Future research may wish to extend this approach and incorporate more of the social aspects of the work situation m studies of employee wellbeing.

Theories of international relations

The substantially revised second edition of this widely-used text provides a broad-ranging introduction to the main theoretical approaches to the study of International Relations. The introduction focuses on the nature of theory in the study of global politics and the discipline's internal debates. The following nine substantially revised and updated chapters, including an entirely new one on Constructivism, provide thorough examinations of each of the major traditional and more recent approaches currently prevailing in the discipline.
