The division of labor, capital, communication technology and economic growth : the case of China 1952–99

The implications of the division of labor, capital, and technology for economic growth have long been a fundamental issue in development economics. This paper employs the bounds testing approach to cointegration to examine the relationship between the division of labor, capital accumulation, communication technology, and economic growth for China over the period 1952–99. We find that in the long run, capital stock and the division of labor both have statistically significant positive effects on growth, while in the short run the effects are not significantly positive. Telecommunication technology, rather surprisingly, has a statistically insignificant impact on growth both in the long run and in the short run. Our findings indicate that there exists a long run equilibrium relationship between capital and the division of labor on the one hand, and economic growth on the other, thereby lending support to the division of labor theory of growth.

Barriers to learners' successful completion of VET flexible delivery programs

In the early 1990s, Australian policymakers began explicitly promoting increased use of flexible delivery in vocational education and training (VET). Some researchers argued that many students lack the learning skills required to deal with the unique demands of flexible delivery. Concerns were also raised about the VET sector's capacity to help students develop needed cognitive and metacognitive skills. A review of the literature revealed wide agreement that students' success in flexible delivery and open and distance education in Australia and elsewhere is generally determined by a complex interplay of factors, including the following: readiness for self-directed learning; ability to balance the time demands of study with other commitments such as family and work; level of literacy; ability to understand and deal with assessment requirements; level of motivation; and previous educational experiences. Two case studies based on the actual experiences of two of six students interviewed about their experiences in flexible VET delivery were reviewed. Both students decided to withdraw from their VET course because of several interconnected factors that built up over time. Both cases illustrated that some problems that can be addressed quickly in face-to-face learning environments are much more difficult to resolve when students are off campus.

The diffusion of policy in contexts of practice : flexible delivery in Australian vocational education and training

Significant changes have occurred over the last decade within the Australian Vocational Education and Training (VET) system. Not least amongst these has been a shift from a predominantly traditional face-to-face classroom model of programme delivery to more flexible models informed by the needs of clients. To lead this revolution, in 1991 the Australian Commonwealth and State Ministers for Training established the Flexible Delivery Working Party. A series of reports followed that sought to develop a policy framework, including a definition of flexible delivery, and its principles and characteristics. Despite these efforts, project funding and national staff development initiatives, several difficulties have been experienced in the ‘take-up’ of flexible delivery; problems that we argue are related to how the dissemination of innovative practice is conceived. Specifically, the literature and research on the diffusion of innovations points to the efficacy of informal social networks ‘in which individuals adopt the new idea as a result of talking with other individuals who have already adopted it’ (Valente, 1995, p. ix). Following a discussion of these issues, the article concludes by arguing the need for research of innovative practice transfer within VET in Australia, using qualitative case study in order to develop an in-depth and rich description of the process, and facilitate greater understanding of how it works in practice.

Interpretation — appropriation : (making) an example of labor process theory

In this article, the author explores ethically problematic relations that may be reproduced within a genre of interpretive organizational research: namely, (U.K.) labor process theory (LPT). Although the author endorses LPT’s critical and explicitly antioppressive values, he argues that interpretive practices employed by core authors contradict the genre’s value base and function to silence and appropriate challenging empirical elements to affirm LPT’s valued interpretive schema. The author draws out deeply problematic implications of such appropriation through highlighting parallels between interpretation, appropriation, and colonization. The author ends by considering the nature of, and possibility for, more ethical “critical” interpretive organizational research.

An application of the flexible multibody approach used to estimate human skeleton loading

Skeletal loading can be estimated using several approaches. The most common approach is based on utilizing mechanical principles and ground reaction forces as predictors for skeletal loading. This method can be considered as a relatively simple approach since it cannot account for muscle forces. Flexible multibody approach allows for estimating skeletal loading and strains within the bones; once bone flexibility, muscle forces, ground reaction forces and the natural motion of a subject have been accounted for. This paper presents a summary that describes how deformable bodies can be introduced to the standard multibody formulation and explains the benefits and drawbacks. As an example of application, models used to assess tibial strains among two subjects are presented. The results of the multibody simulations are compared to in vivo studies, showing acceptable correlation and method performance.

Characteristics and outcomes of patients requiring rapid response system activation within 24 hours of emergency admission

Objectives: 

Emergency responses for clinical deterioration within and beyond 24 hours of emergency admission: Patient outcomes and ICU implications

Introduction: The National Emergency Access Target was implemented to ensure 90% of patients leave emergency departments (EDs) within 4h. The impact of time driven performance on the number of physiologically unstable ward-based patients is unknown. An increase in clinical deterioration episodes potentially leading to adverse events will have resource implications for intensive care units (ICUs).
Objectives: To compare the characteristics and outcomes of patients who required an emergency response for clinical deterioration (cardiac arrest team or rapid response system activation) within and beyond 24 h of emergency admission to general medical and surgical units.
Methods: A retrospective exploratory design was used. The study site was a 365 bed urban hospital in Melbourne. Emergency responses for clinical deterioration during 2012 were examined.
Results: Of 819 emergency responses for clinical deterioration, 587 patients were admitted via ED. The median time to first responsewas59h, 28.4% of patients required this <24 h after admission. One in eight patients required ICU admission. Comparison of patients requiring a response within and beyond 24h of admission showed no significant differences in age, gender, waiting times, ED length of stay or in-hospital mortality rates. Patients in whom first emergency response occurred <24h after admission were less likely to be admitted to ICU immediately following the emergency response (7.6% vs 13.9%, p-0.039), less likely to have recurrent emergency responses during their hospitalisation (9.7% vs 34.0%, p<0.001), and had shorter median hospital length of stay (7 vs 11 days, p<0.001).
Conclusions: Considerable ICU resources were utilised given one in eight patients required ICU admission following emergency response, and patients admitted via the ED constituted 55% of all rapid response system activations. Exploring potential antecedents to clinical deterioration in this cohort may assist in establishing risk management strategies to reduce utilisation of ICU resources.

The comparative efficiency and productivity of labor-managed and capital-managed firms

The available empirical literature comparing the efficiency and productivity of labor-managed and capital-managed firms is reviewed and meta-analysed. The results suggest that labor-managed firms are not less efficient or less productive than capital-managed firms. Labor-managed firms have lower output-to-labor ratios and even lower capital-to-labor ratios. However, the differences in these ratios are not statistically significant. The labor-managed firm's democratic governance, industrial relations climate, and organisational setting do not appear to adversely affect productivity and efficiency. © 1997 by URPE All rights of reproduction in any form reserved.

Development and application of model of resource utilization, costs, and outcomes for stroke (MORUCOS): an Australian economic model for stroke.

Objectives: To outline the development, structure, data assumptions, and application of an Australian economic model for stroke (Model of Resource Utilization, Costs, and Outcomes for Stroke [MORUCOS]). Methods: The model has a linked spreadsheet format with four modules to describe the disease burden and treatment pathways, estimate prevalence-based and incidence-based costs, and derive life expectancy and quality of life consequences. The model uses patient-level, community-based, stroke cohort data and macro-level simulations. An interventions module allows options for change to be consistently evaluated by modifying aspects of the other modules. To date, model validation has included sensitivity testing, face validity, and peer review. Further validation of technical and predictive accuracy is needed. The generic pathway model was assessed by comparison with a stroke subtypes (ischemic, hemorrhagic, or undetermined) approach and used to determine the relative cost-effectiveness of four interventions. Results: The generic pathway model produced lower costs compared with a subtypes version (total average first-year costs/case AUD$15,117 versus AUD$17,786, respectively). Optimal evidence-based uptake of anticoagulation therapy for primary and secondary stroke prevention and intravenous thrombolytic therapy within 3 hours of stroke were more cost-effective than current practice (base year, 1997). Conclusions: MORUCOS is transparent and flexible in describing Australian stroke care and can effectively be used to systematically evaluate a range of different interventions. Adjusting results to account for stroke subtypes, as they influence cost estimates, could enhance the generic model.

Flexible multibody approach in forward dynamic simulation of locomotive strains in human skeleton with flexible lower body bones

A method for bone strain estimation is examined in this article. The flexibility of a single bone in an otherwise rigid human skeleton model has been studied previously by various authors. However, in the previous studies, the effect of the flexibility of multiple bones on the musculoskeletal model behavior was ignored. This study describes a simulation method that can be used to estimate the bone strains at both tibias and femurs of a 65-year old Caucasian male subject. The verification of the method is performed by the comparison of the results with other studies available in literature. The results of the study show good correlation with the results of previous empirical studies. A damping effect of the flexible bones on the model is also studied in this paper.

Haptics interface for modelling and simulation of flexible cables

Virtual reality systems are becoming a must for product and process design, training practices and ergonomic analysis in many manufacturing industries. The automotive sector is considered to be the leader in applying virtual reality (VR) solutions for real-world, non-trivial, problems. Although, a number of commercial 3D engineering tools for digital mockups exist, most of them lack intuitive direct manipulation of the digital mockups. The majority of these 3D engineering tools are constrained to the interaction mainly with rigid objects which is just half the story. To bridge this gap, we have developed a haptics interface for modelling and simulation of flexible objects. The graphical and haptic user interface developed allows the creation of multiple one dimensional (1D) flexible objects, such as hoses, cables and harnesses. The user is required to provide the mechanical properties of the material such as Young's modulus, Poisson's ratio, material density, damping factors, as well as dimensional properties such as length, and inner and outer diameters of the flexible object. Flexilution solver is employed to estimate and simulate the dynamic behaviour of flexible objects in response to external user interaction, whereas Nvidia's generic physics engine is used to simulate the behaviour of rigid objects. A generic communication interface is developed to accommodate a variety of devices without the reconfiguration of the simulation platform.

Individualised, flexible postnatal care: a feasibility study for a randomised controlled trial

Abstract
Background:
Postnatal care in hospital is often provided using defined care pathways, with limited opportunity for more refined and individualised care. We explored whether a tertiary maternity service could provide flexible, individualised early postnatal care for women in a dynamic and timely manner, and if this approach was acceptable to women.
Methods: A feasibility study was designed to inform a future randomised controlled trial to evaluate an alternative approach to postnatal care. English-speaking women at low risk of medical complications were recruited around 26 weeks gestation to explore their willingness to participate in a study of a new, flexible model of care that involved antenatal planning for early postpartum discharge with additional home-based postnatal care. The earlier women were discharged from hospital, the more home-based visits they were eligible to receive. Program uptake was measured, women’s views obtained by a postal survey sent at eight weeks postpartum and clinical data collected from medical records.
Results: Study uptake was 39% (109/277 approached). Most women (n=103) completed a postnatal care plan during pregnancy; 17% planned to leave hospital within 12 hours of giving birth and 36% planned to stay 48 hours. At eight weeks postpartum most women (90%) were positive about the concept and 88% would opt for the same program again. Of the 28% who stayed in hospital for the length they had planned, less than half (43%) received the appropriate number of home visits, and only 41% were given an option for the timing of the visit. Most (62%) stayed in hospital longer than planned (probably due to clinical complications); 11% stayed shorter than planned.
Conclusions: Women were very positive about individualised postnatal care planning that commenced during pregnancy. Given the hospital stay may be impacted by clinical factors, individualised care planning needs to continue into the postnatal period to take into account circumstances which cannot be planned for during pregnancy. However, individualised care planning during the postnatal period which incorporates a high level of flexibility may be challenging for organisations to manage and implement, and a randomised controlled trial of such an approach may not be feasible.
