Abstract
Purpose
This paper aims to present a design and simulation of electrostatic nanoelectromechanical system (NEMS)-based logic gates using laterally actuated cantilever with double-electrode structure that can implement logic functions, similar to logic devices that are made of solid-state transistors which operates at 5 V.
Design/methodology/approach
The analytical modeling of NEMS switch is carried out for finding the pull-in and pull-out voltage based on Euler-Bernoulli’s beam theory, and its numerical simulation is performed using finite element method computer-aided design tool COVENTORWARE.
Findings
This paper reports analytical and numerical simulation of basic NEMS switch to realize the logic gates. The proposed logic gate operates on 5 V which suits well with conventional complementary metal oxide semiconductor (CMOS) logic which in turn reduces the power consumption of the device.
Originality/value
The proposed logic gates use a single bit NEMS switch per logic instead of using 6-14 individual transistors as in CMOS. One exclusive feature of this proposed logic gates is that the basic NEMS switch is structurally modified to function as specific logic gates depending upon the given inputs.

Abstract
Purpose
The purpose of this paper is to report on a quantitative study of the food environment designed to measure aspects of support for healthy eating.
Design/methodology/approach
An ecological view of eating behaviour was taken by examining the food environment that surrounded a military population of interest. Food outlets (n = 34) were assessed using the Nutrition Environment Measures Survey in store (NEMS-S), Nutrition Environment Measures Study in restaurants (NEMS-R) and military Nutrition Environment Assessment Tool (mNEAT) instruments to determine how well food outlets supported healthy eating.
Findings
Despite better-than-average provision of healthy options on-base, the total environment surrounding the military base barely supports healthy eating. Average support to healthy eating was 45 per cent (NEMS) or 27 per cent (mNEAT) of support that could be measured. Individuals accessing this food environment would find few healthy alternatives, little information directing them to healthy choices and pricing and promotion that drives unhealthy eating behaviours.
Research limitations/implications
This study focused on one food environment; replication is recommended to establish foundation data for benchmarking outlets, and further develop these measures for Australian settings. Future studies may assess the media environment to further extend the ecological model used.
Practical implications
A method to measure the food environment is demonstrated which provides formative research insights for use when planning social marketing interventions. Consideration of these influences together with intra- and inter-personal influences offer the potential to better design social marketing healthy eating interventions, by addressing multiple levels within an ecological framework.
Originality/value
This paper answers calls for social marketers to consider the influence of the surrounding environment, using methods not previously used in Australian settings.

Abstract
Purpose
To understand better how professional services firms (PSFs) use networks to gain entry into newly emerging markets (NEMs), to analyze how such firms are assisted in this process by prior networks and to provide a framework of this process.
Design/methodology/approach
The methodology utilised in this study is qualitative and exploratory. Ten interviews across three large firms (legal, finance and media consulting) were used for the data gathering. Analysis incorporated open, axial and selective coding.
Findings
Prior networks provide impetus to the foreign entry aspirations of PSFs and are critical to the process. The specific functions of network actors in the entry process are to influence the firm and to provide intelligence‐gathering, arising from their participatory role in the foreign market. A framework is presented, supporting network theory as a key theoretical underpinning of strategy formulation, decision‐making and implementation by PSFs entering NEMs.
Research limitations/implications
The framework presented in this paper could be tested most appropriately by analysing an extended number of cases, still within a qualitative approach, prior to survey‐testing the extent of the phenomena. Within the scope of the current study, however, the framework is supported by these preliminary findings.
Practical implications
Networks are perceived by PSFs as a medium for capturing market knowledge and as a basis for strategic decision‐making in NEMs.
Originality/value
Network theory is posited as a key theoretical underpinning of core strategy formulation, decision‐making and implementation by professional services entering NEMs.

Abstract
Purpose
The purpose of this paper is to examine the dynamics of Malaysia's new economic model (NEM) formulated to achieve Malaysia's aspiration to become a high‐income nation by 2020. Based on that analysis, the paper seeks to identify areas of research that could profitably be pursued to further the aims and implementation of the NEM. Such identification of research areas would ensure that research and development efforts are aligned to the accomplishment of national growth objectives in tune with the nation's Vision 2020 as well as spearhead development in other developing countries that wish to emulate Malaysia's model.
Design/methodology/approach
The paper adopts a combination of descriptive and analytical methods. Interviews with selected high‐level officials directly involved in the formulation and implementation of the NEM and secondary data and information inform this study.
Findings
Although Malaysia has done well in socio‐economic development, it is now striving hard to get out of the middle‐income trap to become a high‐income nation by 2020. The paper identifies a scholarly research agenda that will find solutions to the many challenges that Malaysia and other developing countries confront in breaking out of the middle‐income trap.
Practical implications
Practitioners will obtain a better appreciation of the strategies that they have to undertake to accelerate economic growth.
Research implications
The issues identified in the paper and the research agenda proposed should aid policy makers, practitioners and academics in carrying out research and development efforts that could aid developing countries formulate strategies to accelerate the development process.
Originality/value
The paper adds to the limited knowledge on the research that has to be conducted in effectively implementing the Malaysian NEM and accelerating the growth path of the emerging economies.

Abstract
The societal role of universities (u-pillar) is a long-standing discussion dividing the education researchers worldwide. Entering the sphere of the eminent Nordic education model (NEM), we aim at grasping its contemporaneity with regard to social value creation (SVC) and to the promotion of equality in education (EiE).
A theoretical review of literature revisits the foundations of the NEM in the light of the postmodern education challenges and the inherent governance practices of higher education institutions (HEIs) in the global eduscape.
One of the oldest HEIs in Denmark, Niels Brock Copenhagen Business College (NBCBC), is here instrumentalized as the target case research. The latter exhibited a sophisticated educational design, oriented toward digital apprenticeship and cumulative proximity to the students’ population of both national and international cohorts.

Abstract
Purpose
This study aims to examine the effects of corporate ownership (government-linked investment companies, GLICs), linearity of GLICs, board ownership and linearity of board ownership on company performance.
Design/methodology/approach
Using panel data from companies that are listed on the Malaysian Stock Exchange during the period of 2000 to 2009, this study uses weighted least square models.
Findings
The results show that GLICs ownership is positively and significantly related to company performance, while board ownership is negatively and significantly related to company performance. These findings suggest that GLICs ownership improves company performance, while board ownership destroys company performance. The results also show that while GLICs ownership has an inverted U-shaped relationship with company performance, board ownership has a U-shaped relationship with company performance.
Research limitations/implications
The theoretical implication of this study is that agency problem decreases in companies with low and high levels of board ownership concentration, while it increases in companies with middle level of board ownership concentration. Furthermore, agency cost decreases in companies with a certain level of GLICs ownership concentration as the government’s New Economic Model (NEM) expects. However, agency cost increases in companies after a certain level of GLICs ownership concentration.
Practical implications
In practical perspectives, this study provides evidence to policy makers that the government’s proposal to reduce GLICs’ investments in Malaysia and diversify them aboard as mentioned in NEM is supported because the decrease in GLICs stakes in certain level may increase company performance. On the other hand, if the policy of the government is to increase GLICs stakes, the company performance may decrease after a certain level of ownership concentration. This study also provides evidence that investors can invest in companies with low and high board ownership concentration. Furthermore, the NEM policy gives investors an opportunity to invest in the companies with GLICs. Reducing GLICs stakes in the Malaysian market and putting them in the international markets, as mentioned in the Malaysian Government’s NEM policy, will create more opportunities for international investors to invest their fund in the Malaysian market. Thus, the emerging markets exist. In addition, the NEM policy also encourages institutional ownerships like domestic and foreign to increase their stakes instead of GLICs in the Malaysian market.
Originality/value
So far, most of the previous studies on GLICs and board ownerships in the Malaysian setting focused on the relationship of the ownership structure with company performance. However, no study has been done to examine the linearity effects of GLICs and board ownerships on company performance. The study is very important to perform to provide the policy makers and investors with clear guidance before their decisions.

This paper seeks to extend the application of the natural neighbour Galerkin method to vibration analysis of fluid‐structure interaction problems.
Abstract
Purpose
This paper seeks to extend the application of the natural neighbour Galerkin method to vibration analysis of fluid‐structure interaction problems.
Design/methodology/approach
The natural element method (NEM) which is a meshless technique is used to simulate the vibration analysis of the fluid‐structure interaction systems. The method uses the natural neighbour interpolation for the construction of test and trial functions. Displacement variable is used for both the solid and the fluid domains, whereas the fluid displacement is written as the gradient of a potential function. Two classical examples are considered: free vibration of a flexible cavity filled with liquid and vibration of an open vessel containing liquid. The corresponding eigenvalue problems are solved and the results are compared with the finite element method (FEM) and analytical solutions to show the accuracy and convergence of the method.
Findings
The performance of the NEM is investigated in the computation of the vibration modes of the fluid‐structure interaction problems. Good agreement with analytical and FEM solutions are observed. Through the notable obtained results, it is found that the NEM can also be used in vibration analysis of fluid‐structure interaction problems as it has been successfully applied to some problems in solid and fluid mechanics during the recent years.
Originality/value
In spite of notable achievements in solving some problems in solid and fluid mechanics using NEM, the vibration analysis of fluid‐structure interaction problems, as considered in this paper, has not been investigated so far.

Abstract
Purpose
This paper aims to provide investors’ views on financing costs and barriers to entry into the electricity generation sector, with a focus on investors’ views on potential impacts on cost of capital from adopting nodal pricing and financial transmission rights (FTRs). The implications for policymakers and policy reforms are also discussed in detail.
Design/methodology/approach
Survey-based data collection of investors and developers in electricity generation, consisting of multiple choice questions from a closed list of discrete choices, binary-choice questions, and questions with free-text/open-ended answers.
Findings
Across survey respondents, weighted-average cost of capital (WACCs) were broadly unchanged over 2019, with increases for undiversified/non-integrated participants offset by decreases for horizontally integrated participants. Cost of equity has risen, whereas cost of debt has fallen. Nodal pricing-cum-FTRs were estimated to increase WACCs by 150–200 basis points p.a. (15–20%), reflecting concerns around the firmness of FTRs and ability to automatically access intraregional settlement residues.
Research limitations/implications
These findings have energy policy implications, namely, the need to consider the interaction between economic theory and real-world financing models when designing and implementing fundamental energy sector reforms.
Practical implications
The need to consider implementation and transitional issues (e.g. grandfathering of existing rights, focusing on reducing the largest barriers to entry) is associated with implementing nodal pricing.
Originality/value
Unique set of survey questions and insights that have not previously been addressed in an Australian context; what-if analysis not previously done in an Australian context

Abstract
Purpose
The electric power industry has been moving from a regulated monopoly structure to a deregulated market structure in many countries. The purpose of this study is to comprehensively review the existing markets to study advantages, issues involved and lessons learnt to benefit emerging electricity markets.
Design/methodology/approach
The paper employs a comprehensive review of existing competitive electricity market models in USA (California), UK, Australia, Nordic Countries (Norway), and developing country (Chile) to analyze the similarities, differences, weaknesses, and strengths among these markets based on publically available data, literature review and information.
Findings
Ongoing or forthcoming electricity sector restructuring activities in some countries can be better designed based on lessons learnt from existing markets and incorporating their own political, technical and economical contexts. A template for design of successful electricity market has also been presented.
Research limitations/implications
This study is limited to a comparative analysis of five markets and can be extended in the future for other existing and emerging electricity markets.
Practical implications
The discussed weaknesses and strengths of existing electricity markets in this study can be practically utilized to improve the electricity industry market structures leading to several social benefits including lower electricity cost.
Originality/value
The comprehensive review and analysis of five existing markets, physically located in different continents, may be used as an assistance or reference guide to benefit the emerging electricity markets in other countries.
