The impact of sociocultural context on strategic renewal
Authors: Au Kevin , Han Stone , Chung Hsi-Mei 
Published: August 2018

PurposeThe purpose of this paper is to contribute a multilevel, cross-national analysis of the role that sociocultural context may play to enrich the understanding of strategic renewal in family firms. The authors conceptualize sociocultural context as consisting of firm-level social contexts and national culture, and propose that: heterogeneous social contexts in family firm management, i.e. family CEO and multigenerational involvement, give rise to mindsets that have differential effects on renewal efforts and that the proposed effects are subject to variation due to the moderation of national cultural dimensions of uncertainty avoidance and power distance.Design/methodology/approachThe authors use unique date set consisting of 959 family firms from 26 countries drawn from a cross-national, quantitative study of family firms.FindingsThe authors found that family CEO is negatively related to renewal across cultures, and this relationship is attenuated by uncertainty avoidance and power distance. In addition, multigenerational involvement is positively related to renewal, and this relationship is enhanced by the two cultural dimensions.Practical implicationsThe authors suggest that decision makers examine how different contexts, practices and cognition contribute to overall dominant logics that exist in firm. In doing so, they can evaluate how logics as a whole affect renewal, and also how different parts of the logics play a role. This overall evaluation will afford managers a holistic picture of renewal forces that operate in family firm and allow managers to make precise changes to enhance strategic renewal.Originality/valueThe findings support the contention that there is cultural-dependent countervailing effects on strategic renewal within family firms.
Design and optimization of a slot antenna for microwave heating of agglomerates
Authors: Kinoshita Takahiro , Sugihashi Atsushi 
Published: August 2018

Purpose
The microwave heating technique can be used in the production of iron for productivity improvement when the consumption of low-quality iron ore increases. Iron-containing dust agglomerates are an important source of iron; however, the crushing strength of raw agglomerates is low, which decreases the yield owing to breaking. Therefore, they need to be dried using a “band dryer” to reduce the amount of excess water and improve their crushing strength. This paper aims to present the structure of an antenna that efficiently provides microwave energy to the agglomerate layer inside the band dryer.

Design/methodology/approach
Electromagnetic field analysis and experiments that simulate inside the band dryer were performed to evaluate the radiation efficiency of the slot antenna for microwave heating of the agglomerate layer in the presence of a metal conveyor.

Findings
The results show that slot height should be larger than the antenna position from the metal conveyor and smaller than the sum of the antenna position and quarter of the guide wavelength, to maximize the radiation efficiency of the antenna. By satisfying this condition, the radiation efficiency was higher than 75 per cent in the experiments.

Originality/value
This paper presents for the first time the optimum relation between slot height and antenna position to apply the microwave heating technique to iron-containing agglomerates in a band dryer.
L’Aquila, central Italy, and the “disaster cycle”, 2009-2017
Authors: Alexander David E. 
Published: August 2018

PurposeThe purpose of this paper is to offer a critical examination of the aftermath of the L’Aquila earthquake of 6 April 2009. It considers the elements of the recovery process that are unique or exceptional and endeavours to explain them.Design/methodology/approachThe analysis is based on a survey and synthesis of the abundant literature on the disaster, coupled with observations from the author’s many visits to L’Aquila and personal involvement in the debates on the questions raised during the aftermath.FindingsSeveral aspects of the disaster are unique. These include the use of large, well-appointed buildings as temporary accommodation and the efforts to use legal processes to obtain justice for alleged mismanagement of both the early emergency situation and faults in the recovery process.Research limitations/implicationsPolitics, history, economics and geography have conspired to make the L’Aquila disaster and its aftermath a multi-layered event that poses considerable challenges of interpretation.Practical implicationsThe L’Aquila case teaches first that moderate seismic events can entail a long and difficult process of recovery if the initial vulnerability is high. Second, for processes of recovery to be rational, they need to be safeguarded against the effects of political expediency and bureaucratic delay.Social implicationsMany survivors of the L’Aquila disaster have been hostages to fortune, victims as much of broader political and socio-economic forces than of the earthquake itself.Originality/valueAlthough there are now many published analyses of the L’Aquila disaster, as the better part of a decade has elapsed since the event, there is value in taking stock and making a critical assessment of developments. The context of this disaster is dynamic and extraordinarily sophisticated, and it provides the key to interpretation of developments that otherwise would probably seem illogical.
Gathering places in the aftermath of Hurricane Harvey
Authors: Nelan Mary M. , Schumann III Ronald L. 
Published: August 2018

PurposeThe purpose of this paper is to introduce the concept of gathering places in disaster recovery, and describe types of active gathering places where residents and aid workers in Southern Texas, USA, came seeking resources, information and emotional support one month after Hurricane Harvey.Design/methodology/approachSemi-structured interviews in the field with 81 residents and 44 aid workers identified active gathering places and their functions. Researchers utilized a snowball sample design to identify and visit further gathering places until saturation. Field observations and a regional damage survey conducted by car add further context to interview data.FindingsIn total, 22 distinct types of gathering places were identified from the 123 unique gathering places documented. Overall, the displacement of residents created an obstacle to their recovery and access to resources and gathering places; residents characterized a lack of formalized emotional support centers – primarily relying on informal gatherings with friends and neighbors to meet their needs; and gathering places were limited in their ability to foster a communal recovery among the residents.Originality/valueThis study addresses a gap in the research, focusing on where and how individuals access resources, information and emotional support in the short-term recovery following a disaster event. This research combines two traditions, hazards geography and disaster sociology, to investigate what gathering places exist one month after a major disaster, where those places are located, and what purpose they serve.
State-of-practice for risk-based quality assurance in state departments of transportation
Authors: Oechler Erick , Molenaar Keith R. , Hallowell Matthew , Scott Sidney 
Published: August 2018

Purpose
Selecting an optimal quality assurance (QA) process can have significant implications on the long-term durability and lifecycle costs of transportation projects. Currently, the approaches used by state departments of transportation (DOTs) to optimize QA are undocumented and the impact of project-specific factors are unknown. The paper aims to discuss these issues.

Design/methodology/approach
State-of-practice was documented via a review of DOT guidance documents, standard specifications and minimum sampling and testing requirements; a survey of 58 state DOT representatives; and interviews with eight DOTs.

Findings
DOT approaches to QA management are very diverse but can be organized into five levels that range from ad hoc visual inspection of materials to DOT-managed sampling and testing. Project size, location and complexity have strong influence on the selection of a QA approach, but DOT demographics and project delivery method are less significant.

Practical implications
Present approaches to the selection of a QA approach are generally informal, subjective and do not involve formal risk analyses. A data-driven approach for transportation projects is clearly needed.

Originality/value
Understanding how state DOTs approach QA method selection will serve as a foundation for new methods of QA optimization.
Behavioural response patterns: an investigation of the early stages of major incidents
Authors: Hanna Sawalha Ihab 
Published: August 2018

Purpose
This paper aims to investigate the different patterns of organizational behavioural responses to major incidents and develop an original classification of these patterns.

Design/methodology/approach
An extensive literature review was made to investigate the different patterns of behavioural responses to major incidents and then to develop an original classification of these patterns. Several sources of information, such as case studies, technical reports, academic journal articles and organizational internal reports were used.

Findings
Organizations respond differently to major incidents. This was clear from the different behavioural patterns investigated and identified. Behavioural patterns determine levels of resilience and ability of organizations to overcome and ultimately survive major incidents.

Practical implications
To promote effective and organized behavioural response patterns to major incidents and improve consistency of responses across the organization, relevant authorities should demonstrate to all private and public enterprises the significance of effective behavioural responses, thus enabling them to better respond to various potential emergencies.

Originality/value
A number of models of human behaviour have been introduced in the literature to understand how people respond to emergency situations. They each take a different perspective on human behaviour but no single theory has emerged as the leading paradigm. This highlights the complexity of understanding human behaviour in such situations and the need for a better classification of behavioural patterns. To the author’s knowledge, this is one of very few studies to investigate, identify and categorize behavioural response patterns to major incidents. This research is expected to be of a substantial value for those interested in improving organizational behaviour during major incidents, as well as those interested in improving organizational resilience.

By providing a critical review of SA supported with a demonstration case study, this study makes a timely contribution for broader awareness and understanding, as well as the application of SA in hospitality.
Repercussions of precarious employment on migrants’ perceptions of healthcare in Greece
Authors: Fouskas Theodoros 
Published: August 2018

Purpose
The purpose of this paper is to investigate the cases of Bangladeshi, Filipina, Nigerian, Palestinian and Pakistani migrant workers and how the frame of their work and employment in precarious, low-status/low-wage jobs affects their perceptions and practices regarding health and access to healthcare services.

Design/methodology/approach
Using qualitative research methodology, the analysis via in-depth interviews focuses on male Bangladeshi, Nigerian, Pakistani and Palestinian unskilled manual and textile laborers as well as street vendors, and female Filipina live-in domestic workers.

Findings
Migrants are entrapped in a context of isolative and exploitative working conditions, i.e., in unskilled labor, textile work, street-vending, personal services, care and domestic work, which lead them to adopt a self-perception in which healthcare and social protection are not a priority.

Social implications
Throughout the paper it has become clear that these precarious low-status/low-wage jobs have an important underside effect on migrants’ lives, intensifying labor and health instability and exposing migrants to employment-generating activities that do not guarantee health safety. In Greek society, the impact of migration on public health is characterized by many as a “time bomb ready to explode,” especially in urban centers. Meanwhile, the economy and particularly the informal sector of the labor market is benefiting from migrant workers. More research is needed as this mode of exploitative labor and precarious employment needs to be adequately addressed to mitigate barriers in the access of labor and healthcare rights.

Originality/value
Via its contribution to the sociology of migration with particular emphasis on labor healthcare, the paper provides evidence that due to their concentration in precarious, low-status/low-wage jobs migrant workers have very limited access to healthcare services. The removal of inequalities and discrimination against migrant workers in accessing healthcare services and medical care is a challenge for South European Union countries and particularly for Greece. However, in spite of this, there is no uniform policy in the management of migrants with respect to their access to health services. The paper will aid debates between policy makers and academics working on migration and inequalities due to the division of labor and health disparities, will contribute to the understanding of the perils attached to precarious, low-status/low-wage jobs and in addressing health inequalities effectively.
The flexibility of industrial additive manufacturing systems
Authors: Eyers Daniel R. , Potter Andrew T. , Gosling Jonathan , Naim Mohamed M. 
Published: August 2018

PurposeFlexibility is a fundamental performance objective for manufacturing operations, allowing them to respond to changing requirements in uncertain and competitive global markets. Additive manufacturing machines are often described as “flexible,” but there is no detailed understanding of such flexibility in an operations management context. The purpose of this paper is to examine flexibility from a manufacturing systems perspective, demonstrating the different competencies that can be achieved and the factors that can inhibit these in commercial practice.Design/methodology/approachThis study extends existing flexibility theory in the context of an industrial additive manufacturing system through an investigation of 12 case studies, covering a range of sectors, product volumes, and technologies. Drawing upon multiple sources, this research takes a manufacturing systems perspective that recognizes the multitude of different resources that, together with individual industrial additive manufacturing machines, contribute to the satisfaction of demand.FindingsThe results show that the manufacturing system can achieve seven distinct internal flexibility competencies. This ability was shown to enable six out of seven external flexibility capabilities identified in the literature. Through a categorical assessment the extent to which each competency can be achieved is identified, supported by a detailed explanation of the enablers and inhibitors of flexibility for industrial additive manufacturing systems.Originality/valueAdditive manufacturing is widely expected to make an important contribution to future manufacturing, yet relevant management research is scant and the flexibility term is often ambiguously used. This research contributes the first detailed examination of flexibility for industrial additive manufacturing systems.
Investigation of wear mechanism of forged steel piston skirt under boundary lubricated conditions
Authors: Jian Zhang , Lijun Deng , Guannan Hao , Shiying Liu 
Published: August 2018

Purpose
With the implementation of new emission standards, the thermal–mechanical coupling load of engine pistons becomes more important. In this case, forged steel material with higher fatigue limit and impact resistance has been applied gradually in piston manufacturing. However, new failure problems emerge, and the wear of skirt under boundary lubrication conditions is an essential problem which needs to be solved urgently.

Design/methodology/approach
In this research, the abrasion testing machine was used to simulate the wear behavior under different conditions of normal pressure, relative velocity and surface roughness. Besides, the wear morphology was observed by scanning electron microscope. Then, the wear model was established by using test results fitting method, offering a way to conduct qualitative analysis for the wear problem under the same conditions.

Findings
The results show that mainly the wear mechanism of the piston skirt under boundary lubricated conditions is adhesive wear and abrasive wear. In addition, the coefficient and wear rate will increase with the increase in the normal load and surface roughness and decrease with the increase in the relative speed. In the wear model, the wear loss is mainly influenced by the normal load, the relative sliding speed and the wear time.

Originality/value
The wear degree of piston skirt was qualitatively obtained in this investigation by factors such as pressure, velocity and so on, and the wear mechanism of forged steel piston skirt under boundary lubrication conditions was also determined. These could provide theoretical support for further optimization of cylinder motion and oil supply system, reduction of friction loss and power loss.
Online infrared spectra detection of lubricating oil during friction process at high temperature
Authors: Jin Yongliang , Duan Haitao , Wei Lei , Chen Song , Qian Xuzheng , Jia Dan , Li Jian 
Published: August 2018

Purpose
This paper aims to investigate the tribological behavior and online infrared spectra of three types of lubricating oils containing dinonyl diphenylamine (DNDA) antioxidant, which are mineral oil (MO), poly alpha olefin (PAO) and trimethylolpropane trioleate (TMPTO), during the friction process at high temperature (temperature rising at first and isothermal holding afterwards).

Design/methodology/approach
A platform of low speed four-ball tribometer equipped with a temperature controller combined with infrared spectrometer was established. MO, PAO and TMPTO base oils were mixed with 1.0 Wt.% DNDA antioxidant, coded as MOa, PAOa and TMPTOa in sequence. The friction coefficient and online infrared spectra of the oils were tested during the friction process of temperature rising at first and isothermal holding afterwards, and the wear tracks of the upper balls were measured using a confocal scanning optical microscope.

Findings
The results indicated that the DNDA antioxidant was depleted to reduce the generation of alcohols and carbonyl products, and the depletion rate of DNDA followed the sequence of MOa > PAOa > TMPTOa. In the temperature rising friction process, the critical transition of friction coefficient was confirmed. The addition of DNDA antioxidant reduced the temperature of the oils at the critical transition of friction coefficient, and the temperature followed the sequence of TMPTOa > PAOa > MOa. After the critical transition, the friction coefficient was first increased and then declined to a steady value; the friction coefficient of MOa increased and declined first, followed by PAOa and TMPTOa. In the steady stage of friction, there was no obvious effect of DNDA on the friction coefficient of the oils. Moreover, DNDA enhanced the wear properties of MOa and PAOa; no obvious improvement was revealed for the wear property of TMPTOa.

Originality/value
The established platform of low speed four-ball tribometer combined with infrared spectrometer successfully realized online testing of the structure changes of lubricating oil during high temperature friction, which can give some reference on the oxidation and friction researches of lubricating oil.

Authors: Wang Yishou , Han Zhibin , Gao Tian , Qing Xinlin 
Published: August 2018

Purpose
The purpose of this study is to develop a cylindrical capacitive sensor that has the advantages of high resolution, small size and designability and can be easily installed on lubricant pipeline to monitor lubricant oil debris.

Design/methodology/approach
A theoretical model of the cylindrical capacitive sensor is presented to analyze several parameters’ effectiveness on the performance of sensor. Numerical simulations are then conducted to determine the optimal parameters for preliminary experiments. Experiments are finally carried out to demonstrate the detectability of developed capacitive sensors.

Findings
It is clear from experimental results that the developed capacitive sensor can monitor the debris in lubricant oil well, and the capacitance values increase almost linearly when the number and size of debris increase.

Research limitations/implications
There is lot of further work to do to apply the presented method into the application. Especially, it is necessary to consider several factors’ influence on monitoring results. These factors include the flow rate of the lubricant oil, the temperature, the debris distribution and the vibration. Moreover, future work should consider the influence of the oil degradation to the capacitance change and other contaminations (e.g. water and dust).

Practical implications
This work conducts a feasibility study on application of capacitive sensing principle for detecting debris in aero engine lubricant oil.

Originality/value
The novelty of the presented capacitance sensor can be summarized into two aspects. One is that the sensor structure is simple and characterized by two coaxial cylinders as electrodes, while conventional capacitive sensors are composed of two parallel plates as electrodes. The other is that sensing mechanism and physical model of the presented sensor is verified and validated by the simulation and experiment.
