Topology optimisation using nonlinear behaviour of ferromagnetic materials
Authors: Mohamodhosen Bilquis Bibi Safoorah , Gillon Frederic , Tounzi Mounaim , Chevallier Loïc 
Published: September 2018

Purpose
The purpose of this paper is to propose a methodology to seek the optimal topology of electromagnetic devices using the density method while taking into account the non-linear behaviour of ferromagnetic materials. The tools and methods used are detailed and applied to a three-dimensional (3D) electromagnet for analysis and validation. Resulting topologies with and without the non-linear behaviour are investigated.

Design/methodology/approach
The polynomial mapping is used with the density method for material distribution in the optimisation domain. To consider the non-linear behaviour of the materials, an analytical approximation based on the Marrocco equation is used and combined with the polynomial mapping to solve the problem. Furthermore, to prevent the occurrence of intermediate materials, a weighted sum of objectives is used in the optimisation problem to eliminate these undesired materials.

Findings
Taking into account the non-linear materials behaviour and 3D model during topology optimisation (TO) is important, as it produces more physically feasible and coherent results. Moreover, the use of a weighted sum of objectives to eliminate intermediate materials increases the number of evaluations to reach the final solution, but it is efficient.

Practical implications
Considering non-linear materials behaviour yields results closer to reality, and physical feasibility of structures is more obvious in absence of intermediate materials.

Originality/value
This work tackles an obstacle of TO in electromagnetism which is often overlooked in literature, that is, non-linear behaviour of ferromagnetic materials by proposing a methodology.

PKC Laundries: a start-up business at the crossroads
Authors: Pagadala Ammani , Gupta Rajiv 
Published: September 2018

Subject area
Strategy

Study level/applicability
Strategic Management course in an undergraduate programme.

Case overview
PKC Laundries started a technology-driven laundry service that would be just a click away for their customers and would provide a quick and satisfying cost-effective solution to the customers’ laundry needs. The business, conceived as a start-up, was based on the asset-light aggregation model which used existing vendors to provide the service. The business has been running for almost two years now but has encountered certain operational challenges of vendor management and in generating sufficient operating profits. At this juncture, the question that is bothering the owners is would it be right if PKC went in for backward integration by investing in an automatic laundry plant to manage the risk of dependency on their vendors or should they strengthen and scale-up the present business model? The owners seem to be in a muddle about their strengths and weaknesses and the foreseeable opportunities and threats and going forward what sort of challenges should they prepare themselves for? This case requires the reader to understand the scenario in which a small and medium enterprise (SME) operates within its micro and macro environment. It then makes the reader think and critically analyse the dilemma the young entrepreneurs are facing and identify the problems and possible strategies to overcome these problems. The case highlights the challenges faced by PKC as an aggregator business and the scope of what PKC can do in the future to strengthen its position. It also explores various marketing management issues such as segmenting, targeting and positioning. The case also helps in understanding strategic management issues such as analysis and formulation and implementation of the strategy.

Expected learning outcomes
The expected learning outcomes are as follows: To understand the micro and macro environmental factors affecting a firm; to understand the issues involved in formulating and implementing a strategy; to understand the challenges faced by a start-up (both operational and for scaling up); and to understand the strategies adopted by the company to develop their business.

Learning from the past? An exploratory study of familial food socialization processes using the lens of emotional reflexivity
Authors: Kharuhayothin Tanyatip , Kerrane Ben 
Published: September 2018

PurposeThis paper aims to explore the parental role in children’s food socialization. More specifically, it explores how the legacy of the past (i.e. experiences from the participant’s own childhood) works to inform how parents, in turn, socialize their own children within the context of food, drawing on theories of consumer socialization, intergenerational influence and emotional reflexivity.Design/methodology/approachTo seek further understanding of how temporal elements of intergenerational influence persist (through the lens of emotional reflexivity), the authors collected qualitative and interpretative data from 30 parents from the UK using a combination of existential–phenomenological interviews, photo-elicitation techniques and accompanied grocery shopping trips (observational interviews).FindingsThrough intergenerational reflexivity, parents are found to make a conscious effort to either “sustain” or “disregard” particular food practices learnt from the previous generation with their children (abandoning or mimicking the behaviours of their own parents within the context of food socialization). Factors contributing to the disregarding of food behaviours (new influencer, self-learning and resistance to parental power) emerge. A continuum of parents is identified, ranging from the “traditionalist” to “improver” and the “revisionist”.Originality/valueBy adopting a unique approach in exploring the dynamic of intergenerational influence through the lens of emotional reflexivity, this study highlights the importance of the parental role in socializing children about food, and how intergenerational reflexivity helps inform parental food socialization practices. The intergenerational reflexivity of parents is, thus, deemed to be crucial in the socialization process.
Mentorship programs in the manufacturing industry
Authors: Bjursell Cecilia , Florin Sädbom Rebecka 
Published: September 2018

Purpose
This paper aims to present a literature review of studies of mentorship programs in the manufacturing industry so as to lay a theoretical basis for learning at work.

Design/methodology/approach
A literature review with focus on mentorship programs in the manufacturing industry was used. A search for relevant peer-reviewed articles, in four databases, rendered 315 hits, but only one article dealt with mentorship programs in an industry similar to the manufacturing industry. Thus, it is concluded that there is a lack of research on this area. The selection criteria were broadened so as to include 16 articles on mentorship programs for learning at work.

Findings
Three dominant areas emerged from this review: definitions of mentorship, characteristics of a good mentor and mentorship program structures. The establishment of a mentorship program requires a clear purpose; contextual knowledge; and adaption to the profession, the organization and to individual needs. In addition to their findings, the authors discuss relationships in mentoring programs, what can be understood by “reading between the lines” and the ongoing digitalization of mentorship programs.

Originality/value
Mentorship has proven itself to be a superior way to learn on the job. This paper provides practical information about establishing mentorship programs in the manufacturing industry, with a particular focus on the moulding industry.
The role of knowledge complexity in administration–society collaborations on knowledge
Authors: Pyrozhenko Vadym 
Published: September 2018

PurposeThis paper engaged in theory-building from social movement and knowledge management (KM) theories and applied the case study method to explore the role of knowledge complexity in administration–society collaborations on knowledge. Complex knowledge is a kind of knowledge that consists of many interdependent elements, some of which are tacit. Complex knowledge creates challenges when external social groups attempt to transfer their knowledge to public organizations. Thus, the purpose of this paper is to investigate the following question: how do social groups acting as knowledge agents transfer their knowledge if it is complex?Design/methodology/approachA single-case study methodology informs the theory-building in this paper. The paper examined a case of collaboration between the natural childbirthing social movement and state maternity hospitals in Russia and Ukraine. The case was constructed from interviews, primary sources and secondary sources.FindingsSocial movement and KM theories were used in a case analysis to formulate theoretical propositions about the complexity of social movement knowledge, why and how movements transfer their knowledge through collaborations with the state, and how administrators assess movement knowledge and its transfer. The case suggests that administrators’ lack of capacity to recognize and deal with complex knowledge results in the underutilization of social groups’ knowledge. In particular, administrators treat complex knowledge as simple, and they misunderstand and underestimate its effects on collaboration.Originality/valueTo the best of this author’s knowledge, this paper is the first attempt in public administration to engage in theory-building from social movement and KM theories.
Do workplace flexibilities influence employment stability? An analysis of alternative work schedules, turnover intent and gender in local government
Authors: Wadsworth Lori , Llorens Jared L. , Facer Rex L. 
Published: September 2018

PurposeThe purpose of this paper is to explore the relationship between the determinants of public employee turnover intent and the use of workplace flexibilities, with particular attention on the role that gender plays on the relationship between these two constructs.Design/methodology/approachUsing a cross-sectional quantitative research design, the data collection specifically targeted employees of US municipalities that had a significant portion of their workforce using some type of alternative work schedule. Nine cities from six different states were included in the data collection.FindingsIn support of prior research and conventional wisdom, the authors find that the use of alternative work schedules is associated with lower expressions of turnover intent, but this relationship is only significant for female municipal employees.Research limitations/implicationsOne limitation of the study is that it is mono-source data. A second limitation relates to the lack of controls for contextual and occupational characteristics. Further research is needed on the relationship between alternative work schedule choice and turnover, particularly exploring how other characteristics might impact the relationship between employment flexibilities and turnover.Practical implicationsOverall, the results of the analysis align with broader observations of the need for increasing workplace flexibilities and scholarship exploring these flexibilities, especially for female employees who are attempting to integrate their work and family responsibilities.Originality/valueThere has been relatively little research exploring the relationship between the determinants of turnover intent and the use of workplace flexibilities at the municipal level of government. This is particularly important given that employment in local government is larger than both federal and state government employment combined in the USA (US Census Bureau, 2017).
Engaging leaders at two hierarchical levels in organizational health interventions
Authors: Karanika-Murray Maria , Gkiontsi Dimitra , Baguley Thom 
Published: September 2018

Purpose
Although visible leader support is an essential ingredient for successful organizational health interventions, knowledge on how leaders at different hierarchical levels engage with interventions is underdeveloped. The purpose of this paper is to explore leader engagement by drawing from the experiences of the intervention team.

Design/methodology/approach
Data from semi-structured interviews with the team responsible for implementing an organizational health intervention in two large UK organizations were used to examine how leaders at strategic (senior management) and operational (line managers) positions engaged with the intervention.

Findings
Thematic analysis uncovered 6 themes and 16 sub-themes covering the leaders’ initial reactions to the intervention, barriers to leader engagement, ways in which the intervention team dealt with these barriers, factors facilitating and factors accelerating leader engagement, and differences in engagement between leadership levels.

Research limitations/implications
This study can inform research into the conditions for optimizing leader engagement in organizational health interventions and beyond. Insights also emerged on the roles of leaders at different hierarchical levels and the value of perspective taking for intervention implementation.

Practical implications
Recommendations for bolstering the engagement of leaders in interventions are offered, that apply to all leaders or separately to leaders at strategic or operational levels.

Originality/value
The experiences of the intervention team who sought to engage leaders at different organizational levels to support the intervention are invaluable. Understanding how leader engagement can be maximized can better equip intervention teams for delivering successful interventions.
Gear fault diagnosis based on a new wavelet adaptive threshold de-noising method
Authors: Cai Jianhua 
Published: September 2018

Purpose
This paper aims to explore a new wavelet adaptive threshold de-noising method to resolve the shortcomings of wavelet hard-threshold method and wavelet soft-threshold method, which are usually used in gear fault diagnosis.

Design/methodology/approach
A new threshold function and a new determined method of threshold for each layer are proposed. The principle and the implementation of the algorithm are given. The simulated signal and the measured gear fault signal are analyzed, and the obtained results are compared with those from wavelet soft-threshold method, wavelet hard-threshold method and wavelet modulus maximum method.

Findings
The presented wavelet adaptive threshold method overcomes the defects of the traditional wavelet threshold method, and it can effectively eliminate the noise hidden in the gear fault signal at different decomposition scales. It provides more accurate information for the further fault diagnosis.

Originality/value
A new threshold function is adopted and the multi-resolution unbiased risk estimation is used to determine the adaptive threshold, which overcomes the defect of the traditional wavelet method.
A FSI-thermal model to analyze performance characteristics of hydrostatic turntable
Authors: Liu Chengpei , Hu Junping 
Published: September 2018

Purpose
This paper aims to study the performance of hydrostatic turntables by using fluid structure interaction (FSI) and thermal effect coupled model.

Design/methodology/approach
A novel fluid-structure-thermal coupled model is set up to study the problem. The FSI technique and computational fluid dynamics (CFD) method are used by this new model, and the thermal effects are also considered. Hydrostatic turntables with different system parameters (oil supply pressure, oil recess depth and surface roughness) are studied under different working conditions (rotational speeds of turntable and exerted external loads). Performance characteristics obtained from this FSI-thermal coupled model and conventional model are presented and compared.

Findings
Theoretical predictions are in good agreement with the experimental data. The results of new FSI-thermal coupled model are more accurate than those of the old conventional model. To acquire better performance of the system, the novel FSI-thermal model becomes necessary for different hydrostatic turntable systems.

Originality/value
This developed model is a useful tool for studying hydrostatic turntables. To get an improved performance, a proper selection of design parameters of the system based on FSI-thermal model is essential.
Audit firms and industry specialization in an emerging economy
Authors: Hegazy Karim , Hegazy Mohamed 
Published: September 2018

Purpose
This study aims to investigate the implications of audit industry specialization on auditor’s retention and growth within an emerging economy. Factors such as whether the firm is a Big 4, a firm with international affiliation, a local firm and the type of industry were studied to analyse the reasons behind audit firm retention and growth.

Design/methodology/approach
This research is based on a field study related to audit firms providing services to listed companies in an emerging economy. The sample includes the top 100 publicly held companies’ in the Egyptian stock market during 2006-2011 for which their annual reports are analysed to determine the audit firms’ retention and growth. An assessment of the continuity of the auditors and the increase in the number of audit clients were also measured.

Findings
The results confirm that industry specialization has an important effect on the auditor’s retention, especially for industries where capital investment is significant such as buildings, construction, financial services, housing and real estate. Big 4 audit firms retained their clients because of their industry specialization and brand name. Evidence was found that good knowledge of accounting and auditing standards resulted in audit firms with international affiliation competing with the Big 4 for clients’ retention and growth.

Originality/value
This study contributes to the existing literature, as it is among the first to provide empirical evidence on auditor retention, growth and auditor’s dominance in an emerging economy such as Egypt.

The anti-GMO advocacy: an institutionalist and systems-theoretic assessment
Authors: Valentinov Vladislav , Hielscher Stefan , Everding Sebastian , Pies Ingo 
Published: September 2018

Purpose
Public debates on the use of genetically modified organisms (GMOs) are strongly influenced by the nongovernmental organization (NGO)-led advocacy, most of which is harshly critical of genetic engineering. This advocacy has resulted in discourse failures marked by the disregard for the scientific consensus on the risks and benefits of GMOs. This paper aims to present a theoretical inquiry into this phenomenon.

Design/methodology/approach
Drawing on American institutionalism and Niklas Luhmann social systems theory, the paper explains these discourse failures in terms of the problematic relationship between institutions and technology.

Findings
Clarence Ayres would likely see these discourse failures as a form of “institutional resistance” to the progress of science and technology. In contrast, Marc Tool’s social value principle stresses the importance of democratic legitimation and public acceptance of new technologies, while being sensitive to the possibility of ideologically biased discourses. It is argued that the institutionalist understanding of the interplay between democracy, science and technology would benefit from a better account of Niklas Luhmann’s concept of “complexity reduction”.

Social implications
The study shows that some NGOs are powerful enough to actively shape, if not manipulate, public attitudes and sentiments against GMOs.

Originality/value
The case of the anti-GMO advocacy calls for a new conceptualization of how democracy, science and technology fit together.
