The purpose of this paper is to present an improved concept of software‐based laboratory exercises, namely a Virtual Laboratory for Engineering Sciences (VLES).

The implementation of distance learning and e‐learning in engineering sciences (such as Mechanical and Electrical Engineering) is still far behind current practice in narrative disciplines (Economics, Management, etc.). This is because education in technical disciplines requires laboratory exercises, providing skill‐acquisition and hands‐on experience. In order to overcome this problem for distance‐learning developers and practitioners, a new modular and hierarchically organized approach is needed.

The concept involves simulation models to emulate system dynamics, full virtual reality to provide visualization, advanced social‐clubbing to ensure proper communication, and an AI tutor to supervise the lab work. Its modularity and hierarchical organization offer the possibility of applying the concept to practically any engineering field: a higher level provides the general framework – it considers lab workplaces as objects regardless of the technical field they come from, and provides communication and supervision – while the lower level deals with particular workplaces. An improved student's motivation is expected.

The proposed concept aims rather high, thus making the work truly challenging. With the current level of information and communication technologies, some of the required features can only be achieved with difficulty; however, the rapid growth of the relevant technologies supports the eventual practicality of the concept. This paper is not intended to present any final results, solutions, or experience. The idea is to promote the concept, identify problems, propose guidelines, and possibly open a discussion.

This paper sets out to evaluate the potential of financial performance benchmarking as an expenditure control tool for a national pathology service comprising both public and private service providers.

Primary data were provided by direct consultation with a wide range of stakeholders, whose experience and perspectives were sought primarily through informal face‐to‐face interviews. The authors analyse these informant contributions alongside official reports and the published literature on dual public‐private health service provision.

Informants identified potential advantages and pitfalls in comparative pathology benchmarking for expenditure control. They also identified some significant negative implications for health service quality and suggested related compromises. Often misunderstood cost benchmarking issues are clarified in the paper.

Several areas of importance for further investigation are suggested.

The paper concludes that appropriate performance benchmarking can be applied to New Zealand pathology services as a useful service rationalisation tool and a realistic price‐signalling device, provided that certain safeguards on health service quality are in place.

General issues complicating financial performance benchmarking across sectors in a mixed economy for health service provision are identified for the guidance of researchers, decision‐makers and planners.

The main targets of the work are analysis and simulation of flying laboratory performance. In particular, synthesis of control system for handling qualities change and evaluation in flight are taken into consideration.

Modification of handling qualities is obtained by applying indirect flight control system (FBW). The properties of the optimal controller are calculated through the indirect (implicit) model‐following method. In particular, the modified version based on the computer simulations is used.

Calculation and simulation concern the synthesis of desired handling qualities of the general aviation aircraft PZL‐M20 “Mewa” equipped with indirect (FBW) experimental flight control system. Results of the simulation show that the flying laboratory has the same properties as modeled aircraft, and it is possible to say that handling properties concern attitude orientation of the experimental aircraft is similar to modeled commuter aircraft.

The result of research can be implemented on a project of the flying laboratory based on general aviation aircraft PZL M20 “Mewa”.

The paper presents the practical approach for synthesis of the “Simplified total in flight simulator” performance which can be used for analysis of handling qualities of general aviation aircraft equipped with FBW. Research of this type focuses on military and transport airplanes however, there are no published works in the area of small aircraft so far.

The paper develops a model for enhancing R&D productivity for Indian public funded laboratories. The paper utilizes the productivity data of five Council of Scientific and Industrial Research (CSIR) laboratories for analysis and to form the constructs of the model.

The weighted average method was employed for analyzing the rankings of survey respondents pertaining to the significant measures enhancing R&D involvement of researchers and significant non-R&D jobs. The authors have proposed a model of productivity. Various individual, organizational and environmental constructs related to the researchers working in the CSIR laboratories have been outlined that can enhance R&D productivity of researchers in Indian R&D laboratories. Partial Least Squares-Structural Equation Modeling (PLS-SEM) was used to find the predictability of the productivity model.

The organizational factors have a crucial role in enhancing the R&D outputs of CSIR laboratories. The R&D productivity of researchers can be improved through implementing the constructs of the proposed model of productivity.

The R&D productivity model can be adapted by the R&D laboratories to enhance researchers’ R&D involvement, increased R&D outputs and achieving self-sustenance in long run.

The R&D laboratories can initiate exercises to explore the most relevant factors and measures to enhance R&D productivity of their researchers. The constructs of the model can function as a guideline to introduce the most preferable research policies in the laboratory for overall mutual growth of laboratory and the researchers.

Hardly any studies have been found that have focused on finding the measures of enhancing R&D involvement of researchers and the influence of significant time-intensive jobs on researchers’ productivity.

The purpose of this paper is to discuss the use of stereoscopic virtual technology in textile and fashion studies in particular to the area of chemical experiment. The development of a designed virtual platform, called Stereoscopic Chemical Laboratory (SCL), is introduced.

To implement the suggested educational approaches of SCL, a set of teaching and learning materials with emphasis on the application methods was revised from the existing subjects. The architecture of SCL includes building of virtual objects with the Autodesk software Maya and designing of interactivity by using Unity, a game engine system. Prototype version of the SCL has been passed to selected academic colleagues and students for further evaluation and application feedback.

Textile students can conduct laboratory experiments associated with coloration and finishing of textile technologies in a stereoscopic 3D and multisensory laboratory, and hence enhance their learning experience. With the use of SCL, students can learn relevant experiment tools, experimental processes, procedures, and safety and health precautions.

There is very limited educational or training approach in applying stereoscopic virtual reality in teaching activities. In the area of textile experiment, the authors could say it is virtual and does not exist in current research domains.

The purpose of this paper is to focus on organizational flexibility and explore its antecedents, organizational structure, and processes, as proposed by network organization theories. The study also explores the possible moderating effects of power distance (Pd) and cultural diversity.

Using self-report data from three different multinational military exercises and one laboratory experiment, the paper explored the relationships between perceptions of flat organizational structure, decentralized processes, and flexibility. The data from each of these studies were analyzed both separately and together.

The analyses revealed that decentralization had the most consistent relationship to organizational flexibility across each of the four studies. Moreover, when the data were analyzed conjunctively, significant positive relationships between decentralization and flexibility and between flat structure and flexibility were observed. No moderating effects of Pd or cultural diversity were found.

The results suggest that decentralizing processes and creating flatter hierarchies may contribute to achieving higher levels of organizational flexibility in military organizations.

The paper contributes to empirical support for the central theoretical propositions of network organizational literature, including moderating factors that are essential in multinational organizational contexts.

The purpose of this paper is to model the relationship between student performance, student attitudes, and computer laboratory environments.

Data were collected from 234 college students enrolled in courses that involved the use of a computer to solve problems and provided the laboratory experience by means of formal closed laboratory classes. The a priori proposed model that student performance can be explained by perceptions of the computer laboratory environment and attitudes towards computer was tested using structural equation modeling.

The proposed model was determined to fit the data reasonably well. These results indicate that student performance scores can be explained by perceptions of the computer laboratory environment and attitudes toward computers.

The theoretical and practical implications of the model concerning student performance within the framework of educational management are discussed.

Introduction The Department of Electrical Engineering (EE) and Computer Science (CS) educates future national defence leaders in the theory and practice of its two disciplines and supports the overall USMA purpose of “providing the nation with leaders of character who serve the common defense”. Electromagnetic field theory and applications are fundamental to electrical engineering and play an important role in the Department's curriculum. In 1986, the Department began a modernization programme to upgrade its engineering curriculum, facilities, and equipment. This article describes the electromagnetics instructional thread in the curriculum and the laboratory facilities supporting that instruction.

The motivation for this paper is to better understand the strengths and limitations of quantitative performance measures in a changing environment. The context is one of organisational change and innovative management. Using a case study approach, the paper presents a history of organisational change and focuses on attempts to drive and assess efficiency through performance measures in a public hospital‐based pathology laboratory. The various financial and non‐financial performance measures used in the laboratory are presented. A discrepancy between accounting reports and laboratory management analyses of costs is reported. The notorious difficulties of costing health services are examined through the dispute that arose about whether the mean cost‐per‐test was increasing or decreasing over a three‐year period. Competing representations of performance are analysed. Whilst the case study looks at a New Zealand example, many of the pressures facing pathology services are typical of medical laboratories worldwide. General issues of performance measurement are discussed.
