Lean and agile integration within offsite construction using discrete event simulation
Authors: Mostafa Sherif , Chileshe Nicholas , Abdelhamid Tariq 
Published: November 2016

Purpose
The purpose of this study is to systematically analyse and synthesise the existing research published on offsite manufacturing/construction. The study aims to highlight and associate the core elements for adopting the offsite concept in different construction contexts. This ultimately facilitates the enhancement of the offsite uptake.

Design/methodology/approach
The research study was carried out through a systematic literature review (SLR). The SLR was conducted to identify and understand the existing themes in the offsite research landscape, evaluate contributions and compile knowledge, thereby identifying potential directions of future research. The grand electronic databases were explored to gather literature on the offsite concept, lean and agile principles and simulation. A total of 62 related articles published between 1992 and 2015 have been included in this study. The relevant literature was systematically analysed and synthesised to present the emerging offsite themes.

Findings
The descriptive and thematic analyses presented in this paper have identified related offsite research studies that have contributed to setting a firm foundation of the offsite concept in different construction contexts. Each of the 62 articles was examined for achieving the aim and objectives of this study, the method of data collection and coverage of offsite themes. The results of the analyses revealed that the articles mostly provide information on the offsite concept and its definitions (53 per cent) and offsite barriers and/or drivers (27 per cent). However, limited attention has been paid to the integration of lean and agile principles (13 per cent) and simulation (7 per cent) within the offsite concept, which are therefore more open to research within the offsite concept.

Research limitations/implications
The literature review highlights the main themes and components of the offsite construction concept. This forms a solid basis and motivation for researchers and practitioners to build on to enhance the uptake of the offsite concept in different contexts. This study also presents a research roadmap within the offsite concept, along with a recommendation for further research to be conducted using the research framework proposed in this study. The framework could lead to validation of using simulation to integrate lean and agile principles within the offsite concept.

Originality/value
This paper presents a systematic review of the literature related to offsite construction in different contexts. The emerging components, that is, offsite definitions, drivers and/or barriers, lean and agile principles and simulation have been highlighted and discussed thematically. A research framework that enables pursuit of the integration of lean and agile principles offsite through the lens of simulation has been proposed. The framework is expected to open up new opportunities on the effectiveness of offsite development in different contexts.
Towards research for shaping Chinese policy and selected papers
Authors: Foo Check Teck 
Published: November 2016

Purpose
This paper aims to make a call for the establishment of a new research journal: a likely title for which would be Chinese Public Management. The background to this is clearly set out here for posterity’s sake. The review of selected papers unveils an emerging trend amongst Chinese researchers for undertaking deeper, cluster-based analyses. See, for example, the insights presented in this issue concerning competitiveness in China’s automobile industry.

Design/methodology/approach
A diary-like account has been made of the series of recent events that sparked the author’s interest in creating a journal to be known as Chinese Public Management. Why is there currently this focus on empirical research for public policy? From the author’s five years’ work for a serial visiting professorship across China, he has found that there are now well-established, substantial databases dedicated to the subject. Even more importantly – as this paper illustrates – a growing community of scholars has become keen to embark upon an in-depth, quantitative research. Perhaps, for the new journal, we would need an editor concentrating specifically on databases. Furthermore, undertaking scholarly work that is still of practical relevance for guiding authorities in their formulations of public policy will add a whole new dimension to the available research.

Findings
There is scope for a new endeavor that documents management research within the public sector in China. This may be seen as a sister journal for “Chinese Management Studies” that focuses on the other, much larger Chinese sector, that is, governmental organizations.

Originality/value
This paper documents the emergence of the necessity for a new journal about management in China.
The influence of localized mechanical stresses on the non-homogeneous distribution of electrical conductivity
Authors: Napieralska-Juszczak Ewa , Napieralski Piotr , Komeza Krzysztof , Zeroukhi Youcef 
Published: November 2016

Purpose
The purpose of this paper is to determine the physical design parameters that influence the total resistance of a twisted conductor (cable). One of the physical parameters characterizing this type of structures is the uneven distribution of resistivity due to hardening, which is the result of stress exerted on the wires during the manufacturing process.

Design/methodology/approach
The authors have developed a method to take into account the effect of localized hardening on the inhomogeneous distribution of electrical conductivity in the distorted structures of the conductor. To achieve this goal, the authors have implemented a mechanical-electrical simulation method. The resistance characteristics have been measured as a function of mechanical stress.

Findings
As demonstrated by the results of measurements conducted on various samples and with various cable design parameters, the resistance of a given material (copper or aluminum), expressed as a function of stress, does not depend on the type of force applied. Therefore, the same characteristics may be applied to various cable designs.

Practical implications
The method presented in this paper enables more detailed investigation of the influence of particular design parameters on the total resistance of a cable. It also provides the ability to determine optimal settings of design parameters.

Originality/value
The approach is distinct from similar studies because it takes into account the deformed geometry of the conductor and the uneven distribution of the resistivity within a filament. In the literature, it is sometimes stated that the distribution of resistivity in a compacted cable is uneven, but its measurement is deemed impossible. This paper provides a method for determining such a distribution.
EV drive efficiency of traction motor considering regenerative braking according to various motor cores
Authors: Shim Hokyung , Kim Jihyun , Hong Jungpyo 
Published: November 2016

Purpose
The purpose of this paper is to study the electric vehicle (EV) drive efficiency of a traction motor considering regenerative braking according to various motor cores.

Design/methodology/approach
A software program was developed to predict the driving performance of an EV. It determines the driving mileage, the required power of the traction motor, and the operation points on a torque-speed map when drive cycles are given. The driving performance is calculated from the battery capacity, vehicle specification, and efficiency map of the traction motor computed using the finite element analysis.

Findings
As a result, the motor core is a significant design variable for raising the driving mileage of an EV. It is noted that the change of electrical steels used for the motor core is the lowest priced method of increasing the driving range by 2 km.

Originality/value
The comparative analysis of motor core by replacing 35PN250 to 25PNX1250F results in improvement effects traveling 4.62 and 5.16 km farther in the Simplified Federal Urban Driving Schedule (SFUDS) and Highway Fuel Economy Driving Schedule (HWFET), respectively. It was also verified that regenerative braking system is able to enhance drive efficiency by 29-31.3 km in the SFUDS and 6.5-7.3 km in the HWFET. From comparison of price rise for increasing driving mileage by 2 km, it is noted that the change of electrical steels used for the motor core is the lowest priced method.

Authors: Lefik Marcin , Gmyrek Zbigniew 
Published: November 2016

Purpose
Estimating the punching process’s impact on the operating parameters of an electrical motor is a special problem especially in the case of fractional power motors. The purpose of this paper is to discuss a method of numerical modelling that is useful for this case.

Design/methodology/approach
The proposed multi-physical FEM approach is based on using professional software in the process of modelling and determining the operating parameters of a low power motor. The basic elements of the approach are built FEM models for which the parameters characterising the damaged portions of the magnetic material were determined. The material properties of this zone were determined both by measurement and by a new analytical approach described in this paper.

Findings
The paper formulates the impact of punching on the operating parameters of a low power motor. Moreover, it formulates the analytical algorithm for the estimation of properties of material in damaged zones.

Research limitations/implications
Experimental verification will still be needed to check the model’s accuracy and applicability to various magnetic materials.

Practical implications
The paper provides an easy approach enabling the calculation of motor operating parameters and a simple and useful algorithm to estimate magnetic material properties in the damaged zone.

Originality/value
The analytical algorithm, as presented here, in conjunction with the measurement results is useful and applicable to estimating the magnetic material properties, which form the basis for accurate FEM calculation.
Effects of driving modes on permanent magnet motor electromagnetic and temperature fields at limit conditions
Authors: Qiu Hongbo , Yu Wenfei , Tang Bingxia , Li Weili , Yang Cunxiang , Wang Yanfeng 
Published: November 2016

Purpose
Taking a 2,000 r/min 10 kW permanent magnet motor as an example, the purpose of this paper is to study the influence of driving modes on the performance of permanent magnet motor at limit conditions, and researched the variation mechanism of motor performance influenced by different driving modes.

Design/methodology/approach
A two-dimensional electromagnetic field model of the permanent magnet motor was established, and a rectangular-wave driving circuit was built. By using the finite element method, the electromagnetic field, current, harmonic content and eddy current loss were calculated when the motor operated at rated load and limit load. On the basis of the motor loss calculation, the temperature field of the motor operating at rated condition and limit condition was researched, and the factors that influence motor limit overload capacity were analyzed. By analyzing the motor loss variation at different load conditions, the change mechanism of the motor temperature field was determined further. Combined with the related experiments, the correctness of the above analysis was verified.

Findings
Permanent magnet synchronous motor (PMSM) driven by sine wave is better compared with brushless direct current motor (BLDCM) driven by rectangular wave in reducing the magnetic field harmonics, motor losses and optimizing the temperature distribution in the motor. The method driven by sine wave could improve the motor output performance including the motor efficiency and the motor overload capacity. The winding temperature is the most important factor that limits the output capability of PMSM operating for a long time. However, because of the large rotor eddy current losses, the permanent magnet temperature is the most important factor that limits the output capability of BLDCM operating for a long time.

Practical implications
The influence of driving modes on the motor magnetic field, losses and temperature distribution, efficiency and overload capacity was determined, and the influence mechanism was also analyzed. Combined with the analysis of the electromagnetic and temperature fields, the advantages of different driving modes were presented. This study could provide an important basis for the design of permanent magnet motors with different driving modes, and it also provides reference for the application of permanent magnet motor.

Originality/value
This paper presents the influence of driving modes on permanent magnet motors. The limit output capacity of the motor with different driving modes was studied, and the key factors limiting the motor output capability were obtained.
Approximations for Brillouin and its reverse function
Authors: Takacs Jeno 
Published: November 2016

Purpose
The mathematical complexity of the BJ(x) Brillouin function makes it unsuitable for most calculations and its application difficult for computer programming in magnetism. Here, its approximation with the tanh function is proposed to ease the mathematical operations for most cases. The approximation works with good accuracy, acceptable in practical calculations. This approximation has already formed the foundation of the “hyperbolic model” in magnetism for the study of hysteretic phenomena. The reversal of the Brillouin function is an important but difficult mathematical problem for practical purposes. Here, a proposal has been put forward for an easy approximation using an analytical expression. This provides a good workable solution for the BJ(x)−1 function dependent on J, the angular momentum quantum number of the material used. The proposed approximation is applicable within the working range of practical applications. The paper aims to discuss these issues.

Design/methodology/approach
The multi-variant Brillouin function is closely approximated by the tanh function to ease calculations. Its mathematically unsolved reversed function is approximated by a simple analytical expression with a good working accuracy.

Findings
The Brillouin function and its reversal can be approximated for practical users mostly for professionals working in Magnetism.

Research limitations/implications
Most if not all practical problems in Magnetism can be solved within the limitations of the two approximations.

Practical implications
Both proposed functions can ease the mathematical problems faced by researchers and other users in Magnetism.

Social implications
Ease the frustration of most users working in the field of Magnetism.

Originality/value
The application of the tanh function for replacing the Brillouin function led to the creation of the hyperbolic model of hysteresis. To the author's knowledge, the reverse function was mathematically only solved in 2015 with a vastly complicated mathematics, and is hardly suitable for practical calculations in Magnetism. The proposed simple expression can be very useful for theorists and experimental scientists.
Mapping information security standard ISO 27002 to an ontological structure
Authors: Fenz Stefan , Plieschnegger Stefanie , Hobel Heidi 
Published: November 2016

Purpose
The purpose of this paper is to increase the degree of automation within information security compliance projects by introducing a formal representation of the ISO 27002 standard. As information is becoming more valuable and the current businesses face frequent attacks on their infrastructure, enterprises need support at protecting their information-based assets.

Design/methodology/approach
Information security standards and guidelines provide baseline knowledge for protecting corporate assets. However, the efforts to check whether the implemented measures of an organization adhere to the proposed standards and guidelines are still significantly high.

Findings
This paper shows how the process of compliance checking can be supported by using machine-readable ISO 27002 control descriptions in combination with a formal representation of the organization’s assets.

Originality/value
The authors created a formal representation of the ISO 27002 standard and showed how a security ontology can be used to increase the efficiency of the compliance checking process.
Consumer trust in Google’s top developers’ apps: an exploratory study
Authors: Harris Mark A. , Chin Amita G. 
Published: November 2016

Purpose
This paper aims to investigate Google’s top developers’ apps with trust badges to see if they warrant an additional level of trust and confidence from consumers, as stated by Google.

Design/methodology/approach
Risky app permissions and in-app purchases (IAP) from Google’s top developers and traditional developers were investigated in several Google Play top app categories, including Editor’s Choice apps. Analysis was performed between categories and developer types.

Findings
Overall, Google’s top developers’ apps request more risky permissions and IAP than do traditional developers. Other results indicate that free apps are more dangerous than paid apps and star ratings do not signify safe apps.

Research limitations/implications
Because of a limited number of Google’s top developers and Editor’s Choice apps, conclusions are drawn from a small sample of apps and not the entire market.

Practical implications
Google’s top developers’ apps are suited well for increasing revenue for Google and developers at the consumer’s expense. Consumers should be wary of top developer trust badges.

Social implications
As the lure for “top free” and “top developer” software is strong among consumers, this research contributes to societal welfare in that it makes consumers aware that Google top developer app trust badges and free apps are more dangerous than traditional developer and paid apps, as they request risky permissions at a much higher frequency. Therefore, consumers should be very careful when downloading apps that are advertised as “top free” or “top developer”.

Originality/value
Google’s top developers’ apps and Editors’ Choice apps have not been investigated from the perspective of permissions and IAP before.
Cost difference of buildings in Kathmandu constructed with and without earthquake safer features
Authors: Subedi Jishnu , Ghimire Ram Mani , Neupane Ram Prasad , Amatya Sweta 
Published: November 2016

Purpose
The purpose of this paper is to investigate increase in the cost of reinforced concrete buildings in Kathmandu valley constructed using earthquake safer features in comparison with that of buildings constructed using conventional approach without earthquake safety features.

Design/methodology/approach
Five buildings constructed using earthquake safer features and five buildings constructed without using these features are selected. A cost comparison of both types of buildings is done, and the total cost is also compared for structural, nonstructural and service components in the buildings.

Findings
The cost analysis of buildings constructed in Kathmandu valley shows that there is 10 per cent increase in cost for earthquake safer construction in comparison to construction using conventional approach. This increase in cost can be a deterrent factor for house owners to switch to safer construction practices which ultimately leads to lack of compliance from house owners. A successful implementation of building code in a country like Nepal, where most of the buildings are constructed from informal sector, requires compliance of the code from all stakeholders. Awareness raising can be a deciding factor for success in building code enforcement.

Research limitations/implications
The study is done for only two types of constructions prevalent in Kathmandu: one using simplified codal method and another using conventional method. Only five samples of each types are taken into consideration. The building sample, however, is typical and representative of the two types of the construction practice.

Practical implications
The information from this study will be useful for making policy decisions for enforcement of building codes and also for assessment of economic loss in future earthquakes.

Social implications
This research output will help to redesign building code enforcement projects in Nepal and other countries in the region with similar issues.

Originality/value
The building samples, analysis and output are original contribution of authors, and it contributes to fulfill the gap for such study.
Governance for health in the Anthropocene
Authors: Hancock Trevor , Capon Anthony G. , Dietrich Uta , Patrick Rebecca Anne 
Published: November 2016

Purpose
The purpose of this paper is to explore the pressing issues facing health and health systems governance in the Anthropocene – a new geological time period that marks the age of colossal and rapid human impacts on Earth’s systems.

Design/methodology/approach
The viewpoint illustrates the extent of various human induced global ecological changes such as climate change and biodiversity loss and explores the social forces behind the new epoch. It draws together current scientific evidence and expert opinion on the Anthropocene’s health and health system impacts and warns that many these are yet unknown and likely to interact and compound each other.

Findings
Despite this uncertainty, health systems have four essential roles in the Anthropocene from adapting operations and preparing for future challenges to reducing their own contribution to global ecological changes and an advocacy role for social and economic changes for a healthier and more sustainable future.

Practical implications
To live up to this challenge, health services will need to expand from a focus on health governance to one on governance for health with a purpose of achieving equitable and sustainable human development.

Originality/value
As cities and local governments work to create more healthy, just and sustainable communities in the years ahead, health systems need to join with them as partners in that process, both as advocates and supporters and – through their own action within the health sector – as leading proponents and models of good practice.
