The reweaving and repaving of the modern Silk Road passes through outsourcing and offshoring activities that have a profound impact on both global business psyche and landscape. Firms, in particular, and their global value chain are being shaped and reshaped through a complex concoction of vertical integration and disintegration. The boundary of the firm and the firm/market interface has been of interest to students of organisation and economics for some time. It has provided the context for Internalisation Theory. Within the new economy, the twin trends of globalisation and advancing technologies are giving rise to a hitherto unknown “worldwide market for market transactions? and increased opportunities for international expansion by firms via market-based modes of organisation. We describe these trends and offer an early modeling approach for explaining why some firm’s externalise the marginal transaction in the so-called new economy. The paper further draws attention on the need to articulate an “Externalisation Theory? that adequately accounts for the firm’s offshoring and outsourcing activities, and that parallels as well as complement “Internalisation Theory? for a full explanation of today’s firms behaviour.

This study adopts integration and differentiation perspectives to examine why unity and diversity of organizational cultures emerged as a function of economic reform, and how subcultural differences were reflected in employees' perceptions of cultural practices. Data were gathered from in-depth interviews and a large-scale survey in two large, state-owned enterprises in north-east China. Results indicated that, although all employees were oriented towards a common set of cultural themes, the two generations of employees did not exemplify the themes in the same way. Specifically, unity was illustrated by employees' desire to maintain Harmony and to reduce Inequality. Diversity was revealed by first-generation employees' higher ratings on Loyalty, Security and even Bureaucracy. The findings are discussed in the light of traditional Chinese cultural values, political ideology and the social context. Implications are drawn for organizational cultural theory and research.

Remotely sensed data have been used extensively for environmental monitoring and modeling at a number of spatial scales; however, a limited range of satellite imaging systems often. constrained the scales of these analyses. A wider variety of data sets is now available, allowing image data to be selected to match the scale of environmental structure(s) or process(es) being examined. A framework is presented for use by environmental scientists and managers, enabling their spatial data collection needs to be linked to a suitable form of remotely sensed data. A six-step approach is used, combining image spatial analysis and scaling tools, within the context of hierarchy theory. The main steps involved are: (1) identification of information requirements for the monitoring or management problem; (2) development of ideal image dimensions (scene model), (3) exploratory analysis of existing remotely sensed data using scaling techniques, (4) selection and evaluation of suitable remotely sensed data based on the scene model, (5) selection of suitable spatial analytic techniques to meet information requirements, and (6) cost-benefit analysis. Results from a case study show that the framework provided an objective mechanism to identify relevant aspects of the monitoring problem and environmental characteristics for selecting remotely sensed data and analysis techniques.

The Integration-Responsiveness framework of Prahalad and Doz (1987) has been used extensively in the international business literature to typify the diverse and often-conflicting environmental pressures confronting firms as they expand worldwide. Although the IR framework has been successfully applied for over a decade, many theoretical and empirical studies have focused on the consequences of these pressures rather than the pressures themselves. Prahalad and Doz identified the economic, technological, political, customer and competitive factors that create the global integration and local responsiveness pressures on the diverse businesses and functions in MNEs. This article explains the methodology, including the procedure for data collection and analysis. The researchers conclude with a discussion of their findings and directions for future research, speculating as to the appropriate definition of the domain of IR pressures and the criteria they might use to validate measures of these.

Children with autistic spectrum disorder (ASD) may have poor audio-visual integration, possibly reflecting dysfunctional 'mirror neuron' systems which have been hypothesised to be at the core of the condition. In the present study, a computer program, utilizing speech synthesizer software and a 'virtual' head (Baldi), delivered speech stimuli for identification in auditory, visual or bimodal conditions. Children with ASD were poorer than controls at recognizing stimuli in the unimodal conditions, but once performance on this measure was controlled for, no group difference was found in the bimodal condition. A group of participants with ASD were also trained to develop their speech-reading ability. Training improved visual accuracy and this also improved the children's ability to utilize visual information in their processing of speech. Overall results were compared to predictions from mathematical models based on integration and non-integration, and were most consistent with the integration model. We conclude that, whilst they are less accurate in recognizing stimuli in the unimodal condition, children with ASD show normal integration of visual and auditory speech stimuli. Given that training in recognition of visual speech was effective, children with ASD may benefit from multi-modal approaches in imitative therapy and language training. (C) 2004 Elsevier Ltd.

In a population-based study of 207 subjects with irritable bowel syndrome (IBS) or functional dyspepsia (FD) and controls (n = 100), we aimed to determine whether dimensions of abnormal illness behavior from the Abnormal Illness Behaviour Questionnaire and aspects of social learning of illness behavior from the Social Learning of Illness Behaviour scale were independent predictors of health care seeking for IBS and FD. Results showed that dimensions of abnormal illness behavior and aspects of social learning of illness behavior (encouragement, reinforcement, and modeling) did not significantly differentiate between consulters and nonconsulters with IBS and/or FD. The Disease Conviction scale (OR = 1.55; 95% CI, 1.15-2.09) of the Abnormal Illness Behaviour Questionnaire was an independent predictor of having a diagnosis of IBS and/or FD, independent of age and gender, psychiatric diagnoses, and symptom severity. We conclude that a belief in the presence of serious pathology characterizes community subjects with IBS and FD, but not health care seeking.

The mechanical behavior of the vertebrate skull is often modeled using free-body analysis of simple geometric structures and, more recently, finite-element (FE) analysis. In this study, we compare experimentally collected in vivo bone strain orientations and magnitudes from the cranium of the American alligator with those extrapolated from a beam model and extracted from an FE model. The strain magnitudes predicted from beam and FE skull models bear little similarity to relative and absolute strain magnitudes recorded during in vivo biting experiments. However, quantitative differences between principal strain orientations extracted from the FE skull model and recorded during the in vivo experiments were smaller, and both generally matched expectations from the beam model. The differences in strain magnitude between the data sets may be attributable to the level of resolution of the models, the material properties used in the FE model, and the loading conditions (i.e., external forces and constraints). This study indicates that FE models and modeling of skulls as simple engineering structures may give a preliminary idea of how these structures are loaded, but whenever possible, modeling results should be verified with either in vitro or preferably in vivo testing, especially if precise knowledge of strain magnitudes is desired.

The discovery and interpretation of microscopic residues on stone artefacts is an expanding front within archaeological science, allowing reconstructions of the past use of specific tools. With notable exceptions, however, the field has seen little theoretical development, relying largely on a rationale in which either individual findings are widely generalized or the age of the site determines the importance of the results. Here an approach to residue interpretation is proposed that draws on notions of narrative, scale, action and agency as one means of expanding the theoretical scope and application of residue studies. It is suggested that the individual resonance of the findings of residue analyses with people in the present day can be used to provide a more nuanced understanding of past actions, which in turn allows both better integration and communication of those findings within and outside the archaeological comm unity, and begins to overcome the problems associated with the typically small sample sizes analysed in stone-tool residue studies.

Comparisons were made of the paediatric content of professional entry-level occupational therapy university program curricula in Australia, New Zealand, and Canada using an ex post facto surveymethodology. The findings indicated that in Australia/New Zealand, paediatrics made up 20% of the total curriculum, but only 13% in Canada. Canadian reference materials were utilized less often in Canadian universities than in Australia/New Zealand. Theories taught most often in Australia/New Zealand were: Sensory Integration, Neurodevelopmental Therapy, Client-Centered Practice, Playfulness, and the Model of Human Occupation. In Canada, the most frequent theories were: Piaget’s Stages ofCognitive/Intellectual Development, Neurodevelopmental Therapy, Erikson’s Eight Stages of Psychosocial Development and Sensory Integration. The most frequently taught paediatric assessment tools in both regions were the Bruininks-Oseretsky Test of Motor Proficiency and Miller Assessment for Preschoolers. Paediatric interventionmethods taught to students in all three countries focused on activities of daily living/self-care, motor skills, perceptual and visual motor integration, and infant and child development.

The article adopts a developmental approach to successful human aging by exploring the concept of generativity in relation to a study of older Australians' lived experiences of involvement in the family and community. Qualitative data, collected through focus group interviews, were analyzed interpretively using recent developments in Erikson's theory of generativity as a framework. As a result, the present study contributes an in-depth understanding of the role of generative acts to the lives of older people. The data provide illustrative support for Erikson's contention of a generativity/stagnation crisis in later life. Involvement in the family and community is seen as a productive and generative activity, which promotes a positive experience of aging. Two further emergent themes are also explored. First, the experiences of study participants illustrate the reciprocal and cyclical nature of grand-generativity, and the importance of intergenerational relationships. Finally, the data contribute to our knowledge of cultural generativity, and in particular the passing on of cultural knowledge through narratives and modeling.

Chemical engineering education is challenged around the world by demands and rapid changes encompassing a wide range of technical and social drivers. Graduates must be prepared for practice in increasingly diverse workplace environments in which generic or transferable attributes such as communication and teamwork together with technical excellence are mandated by prospective employers and society at large. If academe is to successfully deliver on these graduate attributes, effective curriculum design needs to include appropriate educational processes as well as course content. Conventional teacher centred approaches, stand-alone courses and retro-fitted remedial modules have not delivered the desired outcomes. Development of the broader spectrum of attributes is more likely when students are engaged with realistic and relevant experiences that demand the integration and practice of these attributes in contexts that the students find meaningful. This paper describes and evaluates The University of Queensland's Project Centred Curriculum in Chemical Engineering (PCC), a programme-wide approach to meeting these requirements. PCC strategically integrates project-based learning with more traditional instruction. Data collected shows improved levels of student attainment of generic skills with institutional and nationally benchmarked indicators showing significant increases in student perceptions of teaching quality, and overall satisfaction with the undergraduate experience. Endorsements from Australian academic, professional and industry bodies also support the approach as more effectively aligning engineering education with professional practice requirements.

As process management projects have increased in size due to globalised and company-wide initiatives, a corresponding growth in the size of process modeling projects can be observed. Despite advances in languages, tools and methodologies, several aspects of these projects have been largely ignored by the academic community. This paper makes a first contribution to a potential research agenda in this field by defining the characteristics of large-scale process modeling projects and proposing a framework of related issues. These issues are derived from a semi -structured interview and six focus groups conducted in Australia, Germany and the USA with enterprise and modeling software vendors and customers. The focus groups confirm the existence of unresolved problems in business process modeling projects. The outcomes provide a research agenda which directs researchers into further studies in global process management, process model decomposition and the overall governance of process modeling projects. It is expected that this research agenda will provide guidance to researchers and practitioners by focusing on areas of high theoretical and practical relevance.

A major determinant of rural development in China is the way by which rural households integrate with rural industries. Three forms of integration – market integration, vertical integration and integration through local groups – are investigated. Policy measures that may facilitate household integration, household specialisation and market segmentation are identified. Findings for the ruminant livestock sector are widely applicable to other agricultural industries in China.
