The purpose of this paper is to characterize the relationships between air pollutant emissions from heavy duty diesel equipment and highway construction project scope, schedule, and budget. Objectives included estimating total project emissions; developing a daily emissions profile; and developing new emissions estimating metrics based on project scope, schedule, and budget.

The research approach involved collecting real-world data related to project scope, schedule, and budget from two highway case study projects. The data were used to establish an emissions inventory estimating methodology to calculate total emissions for each case study. The total emissions were normalized based on project size, duration, and cost in order to develop new emissions estimating metrics.

The results proved that it is possible to characterize total equipment emissions based on project size, duration, and cost. The new emissions estimating metrics were quantitatively similar for both case studies.

The results were based on two case study projects. Additional data from more projects is needed to provide more highly refined numerical results.

This approach enables project planners and managers to assess the environmental impacts of highway projects along with the financial and time impacts.

Construction equipment is a major contributor to the nation’s air pollution problem. Before pollutant emissions can be managed they must first be measured.

The new emissions estimating metrics are a novel approach to comparing environmental impacts of two or more projects, as well as estimating total emissions for future highway construction projects.

This paper aims to present the framework for a model that can be used to estimate the production rate, activity duration, total fuel use, and total pollutants emissions from earthwork activities. A case study and sensitivity analysis for an excavator performing excavations are presented.

The tool is developed by combining the multiple linear regressions (MLR) approach for modeling the productivity with the EPA's NONROAD model. The excavator data were selected to build the productivity model, and emission factors of all type of pollutants from NONROAD model were used to estimate the total fuel use and emissions.

Results indicate that the excavator productivity model had high precision and accuracy, low bias, with trench depth and bucket size are in the model, it can explain 92 per cent variability of productivity rate data, and can be used as the basis for estimating the fuel quantities that will be required and the total expected pollutant emissions for the project.

The estimating tool proposed in this paper will be an effective means for assessing the fuel consumptions and air emissions of earthwork activities and will allow equipment owners or fleet managers, policy makers, and project stakeholders to evaluate their construction projects. The tool will help the contractors to estimate the fuel quantities and pollutant emissions, which would be valuable information for a preliminary environmental assessment of the project.

Although there are already methods and models for estimating productivity rate and emissions for heavy duty diesel (HDD) construction equipment, there currently is not a means for doing all of these at once.

High quality of provision in higher education is seen as an institutional imperative in the 1990s. This coincides with the need to reduce unit costs and increase productivity. The delivery of these three outputs results in considerable demands being made on staff and places great stress on the need to ensure employee commitment. Organizations are explicitly or implicitly seeking employee commitment through a number of human resource and quality initiatives. One of these means is through employee communication. Briefly examines the theory of employee commitment. Proceeds to examine the role of employee communication in helping to promote and manage employee commitment. Uses survey data related to the attitudes of staff at a British higher education institution to discuss the linkage between communication, commitment and quality. Discusses key issues for those who manage communication in order to attempt to achieve commitment for quality.

A review of the approach adopted by the Management Charter Initiative (MCI) towards the use of management competences, drawing on contemporary research and journal articles, is made. In addition, use is made of insights and experience gained through involvement in the MCI Accreditation of Prior Learning (APL) pilot project conducted at Cheltenham and Gloucester College of Higher Education. Three major assumptions associated with the MCI competence approach are evaluated and a specific facet of the Cheltenham and Gloucester College APL experience, that of high delegate wastage, is examined. An expectancy model of motivation is used along with an action feedback model to illustrate and explain some of the potential reasons for a high drop‐out rate. The model affords an opportunity to provide a rationale to underpin needed action on the part of the major actors within the APL management competence approach. In conclusion, a number of summary propositions predicated by the review are given.

Performance appraisal is a longstanding, widespread and well‐developed practice in industry. Suggests that it possesses considerable potential to facilitate effective human resource management. Also argues, however, that it is often not given the attention it deserves and is flawed in practice. Traces the origins and development of performance appraisal, reviews why and how organizations use it, and concludes by examining who conducts staff appraisal.

Consecration is the process by which producers in creative fields become canonized as “greats.” However, is this the end of the story? Research on consecration focuses on the drivers of consecration but pays little attention to the post-consecration period. Furthermore, the research ignores the dynamics of consecration. To address these gaps, we examine the changing fortunes of a consecrated artist – the musician Phil Collins. We identify the ways in which three actors (fans, critics, and peers) assemble for consecration, disassemble for deconsecration, and reassemble for reconsecration. Examining the changing public image and commercial fortunes of Collins as a solo artist between 1980 and 2020, we identify an N-shaped process of rise-fall-rise that we call the Phil Collins Effect. This effect offers a new way of thinking about how cultural producers gain, lose and regain status in their fields.

The purpose of this paper is to contribute to the literature on innovation and entrepreneurial learning by exploring how SMEs learn and innovate, how they use both formal and informal learning and in particular the role of networks and crisis events within their learning experience.

Mixed method study, comprising 13 focus groups, over 1,000 questionnaire responses from SME managers, and 20 case studies derived from semi-structured interviews.

SMEs have a strong commitment to learning, and a shared vision. Much of this learning is informal through network events, mentoring or coaching. SMEs that are innovative are significantly more committed to learning than those which are less innovative, seeing employee learning as an investment. Innovative SMEs are more likely to have a shared vision, be open-minded and to learn from crises, being able to reflect on their experiences.

There is a need for further process driven qualitative research to understand the interrelationship between, particularly informal, learning, crisis events and SME innovation.

SME owners need opportunities and time for reflection as a means of stimulating personal learning – particularly the opportunity to learn from crisis events. Access to mentors (often outside the business) can be important here, as are informal networks.

This is one of the first mixed method large scale studies to explore the relationship between SME innovation and learning, highlighting the importance of informal learning to innovation and the need for SME leaders to foster this learning as part of a shared organisational vision.

This paper's aim is to critically review the use of Delphi techniques in qualitative research for utilising “expert” opinions and to explore through a detailed example how Policy Delphi can be used by hospitality researchers as an alternative to the more widely used Normative Delphi.

The paper reflects on the research methodology of a project that explored organisational crisis signals detection using Policy Delphi with a criterion sample comprising 16 senior hotel executives involved in crisis management.

The main methodological concerns regarding Delphi are the definition of consensus, the expertise of the panel, its lack of scientific rigour, and – due to its lack of uniformity – reliability and validity of findings. Policy Delphi by default addresses the first since it does not seek consensus and can, through its design and execution, address the remaining concerns.

Carefully designed Policy Delphi can offer a powerful research tool for exploratory research in hospitality, particularly for development of policies and strategies within an organisation. Unlike Normative Delphi, it is not intended as a decision making tool, but rather as a tool to generate options and suggest alternative courses of action for consideration.

The paper presents a valuable research tool that has evaded the attention of many hospitality researchers offering an illustrative example of its use in exploratory research to deliver credible, transferable and confirmable findings.
