Virtual training systems are attracting paramount attention from the manufacturing industries due to their potential advantages over the conventional training practices. Significant cost savings can be realized due to the shorter times for the development of different training-scenarios as well as reuse of existing designed engineering (math) models. In addition, use of computer based virtual reality (VR) training systems can shorten the time span from computer aided product design to commercial production due to non-reliance on the hardware parts for training. Within the aforementioned conceptual framework, a haptically enabled interactive and immersive virtual reality (HIVEx) system is presented. Unlike existing VR systems, the presented idea tries to imitate real physical training scenarios by providing comprehensive user interaction, constrained within the physical limitations of the real world. These physical constrains are imposed by the haptics devices in the virtual environment. As a result, in contrast to the existing VR systems that are capable of providing knowledge generally about assembly sequences only, the proposed system helps in cognitive learning and procedural skill development as well, due to its high physically interactive nature.

Australian businesses will face profound and wide-ranging structural impacts during their transition to a low carbon footprint economy. This paper synthesizes the impacts for the firm during the transition and identifies the crucial impact variables. In doing so, it explores the link between the opportunities and benefits, costs, risks and structural changes and evaluates the challenges in managing the multiple impacts. The paper provides a conceptual model that will assist decision-makers deal with risk management or bottom-line protection issues as well as exploiting the business opportunity the new regulatory environment will produce. The model argues for a holistic corporate governance mechanism, with responsibility and accountability of climate change risk management placed with the board of directors and senior management. The literature review is presented first, followed by the discussion and the model. Future empirical research direction is also presented with the development of a series of propositions for testing.

Service industries hold an increasingly dynamic and pivotal role in today’s knowledge-based economies. The logistics industry is a classic example of the birth and development of a vital new service-based industry, transformed from the business concept of transportation to that of serving the entire logistical needs of customers. Quantum advances in science, technology, and communication in the new millennium have compelled firms to consider the potential of the so-called new “resources” (technology, knowledge and relationship networks) that are essential if firms are to operate effectively within the emerging business model, and to utilise the opportunities to innovate and gain market leadership. Through an extensive literature review, this paper examines the factors that nurture innovation in logistics services, identifies the contributions of the new “resources” and, using industry examples, examines the application of these resources to logistics firms as they assume an extended role within the new business model

Purpose – The purpose of this paper is to elucidate information on what creates the different types of knowledge.

Design/methodology/approach – In the conceptual model it is argued that the concept of social capital provides an interesting view on the creation of market-specific and firm-specific knowledge.

Findings – The major finding from the paper is that knowledge is an important by-product of an alliance forming process, a process commonly termed as alliance learning.

Research limitations/implications – Both market-specific and firm-specific knowledge have implications on two main types of alliance learning, that of mutual and non-mutual learning.

Practical implications – Alliance managers need to be aware that knowledge is a key driver as well as a beneficial outcome in the formation of alliances.

Originality/value
– This paper examines how the different types of knowledge evolve and how these different types of knowledge impact upon alliance learning.

Purpose – The objective of this paper is to introduce and describe a conceptual framework of corporate and business ethics across organizations in terms of ethical structures, ethical processes and ethical performance.

Design/methodology/approach – A framework is outlined and positioned incorporating an ethical frame of reference in the field of organizational chain management.

Findings – A number of areas and sub-areas of corporate and business ethics are framed in the context across organizations.

Research limitations/implications – The introduced framework should be seen as a seed for further development and refinement. It provides opportunities for further research of ethical concerns across organizations.

Practical implications – Organizations may benefit from the findings and insights presented and they may be used to enhance their ability to manage, monitor and evaluate ethical business practices across organizations.

Social implications – Changing societal and market patterns may enforce organizations to address ethical concerns across organizations. A myopic approach restricted to the judicial system may become insufficient and unsatisfactory from the perspective of other stakeholders of the organization.

Originality/value – The framework makes a contribution bringing in ethical concerns across organizations, providing a basis for their ethical values and culture, as well as asymmetric relationships in terms of power and dependence. The authors believe that a true learning organization needs to realise the importance of an extended view of its endeavors of corporate and business ethics in terms of ethical structures, ethical processes and ethical performance across organizations.

Addressing the diversity in information requirements across the enterprise is a central challenge in enterprise content management. Enterprise information portals (EIPs) hold promise in this regard, offering each user a gateway to customized and personalized content. However, in large organizations EIP implementers face the complexity of tailoring portals for potentially thousands of users. A conceptual framework based on marketing fundamentals is developed to inform EIP implementation in this respect. It is argued that EIP implementers should view their user community as a number of distinct segments in order to address divergent needs more specifically (as opposed to a ‘one size fits all’ approach). For each identified segment, a ‘mix’ of content (product), distribution (place), promotion and price (cost) should be considered. The framework is applied to two cases of EIP implementation in large organizations. It is proposed that segmentation enables better planning of the overall EIP implementation effort. Considerations such as the number of user segments, customization, and personalization of content, and the funding of EIP development in large organizations are also discussed. The concepts elaborated here also hold theoretical relevance for other IS implementation contexts that involve very large usercommunities with diverse information

Obesity and being overweight affect almost half of all women of childbearing age, with postpartum weight retention (PWR) being a key contributing factor. Retention of postpartum weight has a number of negative health implications for mothers and offspring, including longer-term higher body mass index (BMI). There is increasing evidence that psychological factors are associated with PWR, including depressive symptoms, anxiety, stress, and body dissatisfaction. However, what is less known is how these psychological factors might interact with maternal physiological and physical weight factors, sociocontextual influences, pregnancy-related medical factors, and maternal behaviours to lead to PWR. We have incorporated identified psychological influences within an empirically supported, multifactorial, conceptual model of hypothesised predictors of PWR, and argue that a systematic and rigorous evaluation of this conceptual model will inform the development of appropriate prevention strategies.

In a developing nation such as India, the national government is pursuing the pathway of ICT supported decentralized programs, to combat endemics, in the social contexts of each State. The State of Kerala, which has been an exemplar for development, has become susceptible to endemics, brought in by urbanization and non-resident Indian population and compounded by environmental disasters. In this paper, the authors contend that the psyche of the community which has changed from social amity to self-interest need to be re-awakened with the power of ICTs and Internet, so as to efficiently combat endemics. The authors also propose a preliminary framework for emergency responses based on existing ICT systems, recommended by the national government, to fit the context.

This article adds to the ongoing debate on the relationship between poverty reduction, profits, and environmental sustainability. Drawing from the literature, it presents a conceptual model with propositions to explain how social entrepreneurs can lead to sustainable development in developing countries. These propositions are further strengthened by using a descriptive case of Waste Concern—an initiative of social entrepreneurs—in Bangladesh. Findings illustrate that, despite contextual constraints in developing countries, it is possible to have sustainable development with no trade-off between poverty reduction and environmental sustainability. This win-win outcome is possible through the innovative approaches and creative thinking of social entrepreneurs who, rather than being hindered by contextual constraints, act as catalysts for sustainable development. The findings have implications for academics and policy-makers, highlighting the significance of supporting social entrepreneurs to come up with innovative methods for sustainable development.

Screen media (television, computers, and videogames) use has been linked to multiple child outcomes, including obesity. Parents can be an important influence on children's screen use. There has been an increase in the number of instruments available to assess parenting in feeding and physical activity contexts, however few measures are available to assess parenting practices regarding children's screen media use.

A working group of screen media and parenting researchers convened at the preconference workshop to the 2012 International Society for Behavioral Nutrition and Physical Activity (ISBNPA) annual meeting, “Parenting Measurement: Current Status and Consensus Reports,” to identify and prioritize issues in assessing screen media parenting practices.

The group identified that screen media use can pose different risks for children, depending on their age and developmental stage, across physiologic, psychosocial, and development outcomes. With that in mind, a conceptual framework of how parents may influence their child's screen-viewing behaviors was proposed to include the screen media content, context of viewing, and amount viewed.

A research agenda was proposed to prioritize a validation of the framework and enhance the ability of researchers to best assess parenting influences across the three domains of content, context and amount of children's screen media use.

Obesity prevention interventions through dietary and physical activity change have generally not been effective. Limitations on possible program effectiveness are herein identified at every step in the mediating variable model, a generic conceptual framework for understanding how interventions may promote behavior change. To minimize these problems, and thereby enhance likely intervention effectiveness, four sequential types of formative studies are proposed: targeted behavior validation, targeted mediator validation, intervention procedure validation, and pilot feasibility intervention. Implementing these studies would establish the relationships at each step in the mediating variable model, thereby maximizing the likelihood that an intervention would work and its effects would be detected. Building consensus among researchers, funding agencies, and journal editors on distinct intervention development studies should avoid identified limitations and move the field forward.

Actors in the built environment are increasingly considering environmental issues alongside functional and economic aspects of development projects. However, to date in Australia and internationally, there have been few practical examples of integrated applications of sustainability principles in the built environment across all lifecycle phases. In response to this gap, this paper proposes a conceptual framework based on the principal that early intervention is the most cost-effective and efficient means of implementing effective strategies for sustainability. A strategic environmental assessment (SEA) approach is forwarded as an umbrella analytical framework, assembled from analytical methods which are strategically 'tiered' to inform stages of the project decision-making process. Practically applied and timed accordingly, the framework can allow assessments to be targeted towards appropriate decision making levels and enable better decision-making and more efficient resource allocation for major infrastructure development projects.

Purpose
The Rapid Assessment of Disability (RAD) questionnaire was developed to provide governments and development agencies with an appropriate instrument to determine the prevalence of people with disability within their target populations, and to design and evaluate the effectiveness of disability inclusive activities in addressing their priorities and needs.
Methods
The RAD questionnaire was developed using two conceptual frameworks: the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD), and the International Classification of Functioning, Disability and Health (ICF). Existing instruments were reviewed to inform the structure and content of the RAD questionnaire. The RAD questionnaire that was developed for field testing in Bangladesh comprised both a household questionnaire and a questionnaire for individuals within each household, with 5 sections: 1) Demographic information, 2) Assessment of functioning, 3) Awareness of rights of people with disability, 4) Well-being and quality of life, 5) Participation in the community.
Prior to field-testing the RAD questionnaire in Bangladesh, a qualitative study was conducted to ensure the relevance of the questionnaire in the context of a developing country. In-depth interviews with 9 people with disability and a focus group of 8 parents of children with disability were conducted in Dhaka, Bangladesh.
Results
Qualitative findings highlighted factors relevant to the lives of people with disability in Bangladesh, including discrepancies between the awareness and attainment of rights for people with disability, the wellbeing of people with disability and their families, as well as numerous barriers to full participation in their community. While the findings confirmed that the design and content of the questionnaire reflected all these aspects, some changes were made to the items in the questionnaire to ensure that it reflected the views of people with disability from the context of a developing country.
Conclusions and Implications
This qualitative study was an important step in the development of the RAD questionnaire as it helped to achieve its aim - namely, to establish the prevalence of disability and to assist in the design and evaluation of disability inclusive interventions in the setting of a developing country.

A reliable hydrograph separation method is necessary for surface runoff modeling and hydrological studies. This paper investigates and compares the separation characteristics of two single-parameter digital filters, which are herein referred to as the one-parameter algorithm and the conceptual method. The application of the one-parameter algorithm was found to be restricted to low and medium baseflow separations, with a maximum separation limit of 50% of the total runoff hydrograph. The one-parameter algorithm was also observed to produce unrealistic sharp peaks under the peaks of the measured hydrograph when recession constant is smaller than 0.96. On the other hand, the conceptual method is applicable even for catchments fed largely by groundwater discharge. However, a reliable estimation of recession constant is a prerequisite for applying the conceptual method for large baseflow separations. Based on the hydrograph separation results, useful empirical relationships were developed for a partially urbanized watershed to estimate total runoff and direct runoff from the measured rainfall depth. The relationships between rainfall depth and total runoff depth and rainfall depth and direct runoff depth were found to be well represented by linear equations. The empirical relationships were then applied to estimate the long-term contribution of baseflow and surface runoff to total runoff at the study site. Baseflow was found to contribute about 58–61% of the annual total runoff.
