Agility in assembly systems: a comparison model
Authors: Barbazza Luca , Faccio Maurizio , Oscari Fabio , Rosati Giulio 
Published: July 2017

Purpose
This paper aims at analyzing different possible assembly systems, including innovative potential configurations such as the fully flexible assembly systems (FAS), by defining a novel analytical model that focuses on the concept of agility and its impact on the whole system performance, also evaluating the economic convenience in terms of the unit direct production cost.

Design/methodology/approach
The authors propose a comparison model derived by Newton’s second law, introducing a quantitative definition of agility (acceleration), resistance of an assembly system to any change of its operative state (inertia) and unit direct production cost (force). Different types of assembly systems (manual, flexible and fully FAS) are analyzed and compared using the proposed model, investigating agility, system inertia and their impact on the unit direct production cost.

Findings
The proposed agility definition and the proposed comparison model have been applied considering different sets of parameters as independent variables, such as the number of components to assemble (product model complexity) and the target throughput of the system. The main findings are a series of convenience areas which either, for a given target unit direct production cost (force), defines the most agile system to adopt or, for a given target agility (acceleration), defines the most economical system to adopt, as function of the independent variables.

Originality/value
The novelty of this work is, first, the analytical definition of agility applied to assembly systems and contextualized by means of the definition of the new comparison model. The comparison between different assembly systems on the basis of agility, and by using different sets of independent variables, is a further element of interest. Finally, the resulting convenience areas represent a desirable tool that could be used to optimally choose the most suitable assembly system according to one or more system parameters.
Agricultural price volatility and speculation by commodity index funds: a theoretical analysis
Authors: Gohin Alexandre , Cordier Jean 
Published: July 2017

Purpose
The role that speculation in futures markets plays during food price spikes is a subject of lively dispute. This issue is often addressed with empirical analyses. They suffer from data limitations and focus on the short-term impacts. The paper aims to discuss these issues.

Design/methodology/approach
The authors develop a theoretical model to explain the behaviour of speculators and producers in futures and cash markets. Compared to the only two theoretical analyses by Vercammen and Doroudian where informational externalities are excluded and by Fishe et al. where production responses are excluded, the authors introduce both informational externalities and lagged production responses.

Findings
The authors find that the expanded net long positions of commodity index funds (CIF) are inconsistent with lower stock levels that typically prevail before the price spikes. These positions stimulate production, hence stocks, before the price spikes. Thus they contribute to soften the price volatility.

Practical implications
The simulation results indicate that before imposing new regulations on financial markets, such as position limits on index funds, their beneficial medium-term effect as a hedging instrument for commercial participants should not be omitted or underestimated.

Originality/value
Because the authors develop a second-best theoretical framework, the authors find that CIF are not a systematic cause of medium-term market swings.
Masking neo-liberal development: Polanyi, rule of law and dis-embedding dynamics
Authors: Findlay Mark 
Published: July 2017

Purpose
Polanyi in his analysis of market dis-embedding suggests a drift in economic relations from the social to the fictitious. The purpose of this paper is to add two crucial components to the dis-embedding dynamic: rule of law discourse as a market force away from the social, and through suspension of imagination and of disbelief, the incongruous compatibility of actual and fictional markets that further works against embedding.

Design/methodology/approach
Theory building through the application and testing of the Polanyian market dis-embedding analysis is a central concern for the paper. Through the example of foreign direct investment (FDI) and the manner in which the rule of law discourse masks neo-liberal development inequities, the paper offers an understanding of the forces behind market dis-embedding North to South Worlds and the manner in which through the collusion of legal orientalist, the true impact of the development inequities are concealed.

Findings
The empirical value of the theorising is to allow for studies on the impact of FDI on fragmented South World market economies using Polanyian dis-embedding refined by the suspension of critique which the rule of law discourse enables.

Originality/value
The masking functions of the rule of law discourse in global trade contexts, the paper argues, conceal stark market power asymmetries hardwired into South World development policy through post-colonial free-trade regimes. The legal certainty and commercial predictability that the institutions and processes of dispersed law are said to ensure, have an established market relationship with global trade. However, while resting on ideologies of liberty and equality, the rule of law discourse hides their market suspension in favour of stabilising and auctioning universally inequitable market conditions for the purposes of the neo-liberal global trade agenda.
Physics-based integrated vehicle health management system for predicting the remaining useful life of an aircraft planetary gear transmission
Authors: Cubillo Adrian , Vermeulen Jeroen , Rodriguez de la Peña Marcos , Collantes Casanova Ignacio , Perinpanayagam Suresh 
Published: July 2017

PurposeIntegrated vehicle health management has been developed for several years in different industries, to be able to provide the required inputs to determine the optimal maintenance operations depending on the actual health status of the system. The purpose of this paper is to demonstrate the potential of a physics-based model (PbM) for prognostics with a real case study, based on the detection of incipient faults and estimate the remaining useful life of a planetary transmission of an aircraft system.Design/methodology/approachMost of the research in the area of health assessment algorithms has been focused on data-driven approaches that are not based on the knowledge of the physics of the system, while PbM approaches rely on the understanding of the system and the degradation mechanisms. A physics-based modelling approach to represent metal-metal contact and fatigue in the gears of the planetary transmission of an aircraft system is applied.FindingsBoth the failure mode caused by metal-metal contact as caused by fatigue in the gears is described. Furthermore, the real-time application that retrieves the results from the simulations to assess the health of the system is described. Finally the decision making that can be executed during flight in the aircraft is incorporated.Originality/valueThe paper proposes an innovative prognostics health management system that assesses two important failure modes of the planetary transmission that regulates the speed of the generators of an aircraft. The results from the models have been integrated in an application that emulates a real system in the aircraft and computes the remaining useful life in real time.
Splitting to survive: understanding terrorist group fragmentation
Authors: Morrison John Francis 
Published: July 2017

Purpose
From Al-Qaeda to the IRA, almost all terrorist organisations have experienced splits in some shape or form. This can spell the dawn of violent spoiler groups, but it may equally play a significant role in the overall politicisation of a group. The purpose of this paper is to provide a greater understanding of these splits by assessing the issue from a political organisational perspective.

Design/methodology/approach
The author proposes that by addressing splits through the lens of organisational survival, we may gain a greater insight into the process which takes place in the lead up to, and in the aftermath of, organisational cleavage.

Findings
It is posited that the rationale behind schism can, at times, be the result of a desire from at least one side to maintain the survival of the organisation in a form they both respect and recognise. In order to achieve this, it might require forming an independent, autonomous organisation, or alternatively promoting the exit of internal factional competitors.

Research limitations/implications
Within the paper, three organisational hypotheses are proposed. It is vital that in order to assess their validity, these are empirically tested by future researchers.

Practical implications
To be able to counter terrorist organisations, one must first have an understanding of the external and internal events and processes. While much of our attention is on understanding paid to the external violent activity of the groups, we must also develop a significant understanding of the non-violent internal activities as well. This paper provides a theoretical basis for understanding one of these process, organisational split.

Originality/value
By addressing splits from an organisational survival viewpoint, the paper challenges the previously held assumption that splits should be analysed as part of the “end of terrorism.”
Can policy makers count with positive impact of entrepreneurship on economic development of the Czech regions?
Authors: Dvouletý Ondřej 
Published: July 2017

PurposeThe purpose of the present study is to empirically investigate the impact of the newly established entrepreneurial activity on economic development of the Czech NUTS 3 regions during the period of years 2003-2015.Design/methodology/approachAn econometric approach was used to validate the stated hypotheses assuming a positive relationship between the new entrepreneurial activity and regional economic growth and a negative relationship between the new entrepreneurial activity and unemployment rate. For the methods, regression models with fixed effects were estimated on the panel that included 13 Czech regions, covering the period of years 2003-2015. The new entrepreneurial activity was classified into two forms – rate of newly established self-employed set-ups per capita and rate of newly established business companies and partnership set-ups per capita.FindingsDifferent impacts of newly established business companies and the self-employed were found on real gross domestic product (GDP) per capita. Only the higher rates of newly established business companies and partnership were associated with higher levels of GDP per capita in the Czech regions, and no impact was found for the rate of new self-employed set-ups. Nevertheless, both forms of newly established entrepreneurial activity were associated with lower unemployment rates in the Czech regions; however, the impact of newly established business companies was significantly higher. The obtained results have several policy implications, which are discussed in the present paper.Practical implicationsSupport of entrepreneurship in the Czech regions may improve the situation on the local labour markets and may deliver new job opportunities through the newly established enterprises. The Czech entrepreneurship policies focused on the growth of GDP and economic boom should be oriented more on the support of high-growth enterprises (unicorns).Originality/valueThe empirical analysis was conducted on the basis of the research gap in the studies related to the impact of the newly established entrepreneurial activity on the economic development of the Czech regions. Obtained results have several policy implications, which are discussed in the present paper.
Exchange rate undervaluation and sectoral performance of the South African economy
Authors: Njindan Iyke Bernard 
Published: July 2017

Purpose
The purpose of this paper is to uncover the channels through which real exchange rate undervaluation influences the performance of the South African economy.

Design/methodology/approach
The author decomposes the South African economy into three sectors: agriculture, industry, and services. Specifying a model for each sector, the author employs the ordinary least squares (with Newey-West and robust standard errors) and generalized method of moments estimation techniques. The annual time series data cover the period 1962-2014.

Findings
The author finds that real exchange rate undervaluation exerted a positive influence on agriculture and industry, and a negative impact on services.

Research limitations/implications
The results have practical policy implications, which are discussed in the paper.

Originality/value
Although the growth effect of real exchange rate undervaluation has been well established in the literature, the channels through which this occurs has received limited attention. Prior to this study, no study has considered the impact of real exchange rate undervaluation on the economy through the various sectors in the South African context.
Substance misuse in personality disorder and schizophrenia: findings and clinical implications from a high secure hospital
Authors: Cappai Alessandra , Wells Jodie , Tapp James , Perkins Derek , Manners Anna , Ferrito Martha , Gupta Nitin , Das Mrigendra 
Published: July 2017

Purpose
Substance misuse (SMU) is widely prevalent in mentally disordered offenders and is linked with violence and offending behaviour. There is however, a scarcity of literature dedicated to investigating SMU and its clinical correlates in relation to patients detained within high secure hospital settings. The purpose of this paper is to investigate the extent and severity of SMU and corresponding treatment needs in patients with a primary diagnosis of personality disorder (PD) in comparison with mental illness (MI) in a high secure hospital.

Design/methodology/approach
The responsible clinicians of all patients (n=240) detained in a high secure hospital were asked to record information using a SMU screening questionnaire over a ten-month period. Details requested included substance type, history of past use and assessment and treatment needs. Data were recorded and then analysed: descriptive statistics were conducted to report historical use of substances, cross tabulations and χ2 analysis explored the relationship between SMU and treatment status and diagnosis and offending behaviour and a means comparison analysis was employed to explore length of stay and treatment of SMU.

Findings
A total of 230 questionnaires were returned (95 per cent of the patient population). A history of SMU was reported in 88.6 per cent of the sample, with alcohol and cannabis misuse being the most prevalent. At least one substance had been abused by 74.3 per cent of the sample. In two-thirds of the sample, SMU was linked with the onset of mental health problems and symptom exacerbation, including violence. Interestingly, patients with a diagnosis of MI as compared with PD were more likely to have used substances (93.3 per cent compared to 81.9 per cent) and were more likely to need treatment for SMU (64.3 per cent compared to 36.8 per cent). In those with an MI diagnosis, SMU was more likely to be linked with violence and index offence (74.3 per cent compared to 59.0 per cent).

Practical implications
SMU is significantly prevalent in high risk mentally disordered offenders and linked to onset of mental health problems and offending. Patients with schizophrenia have a higher prevalence of SMU than PD and are likely to be more in need of treatment. Violence and offending are more likely to be related to SMU in schizophrenia than in PD.

Originality/value
This study substantiates existing evidence that SMU contributes to mental health problems and criminogenic behaviour. Furthermore, the study reports new findings that characterize differences of the relationship of SMU to offending in schizophrenia and PD in forensic psychiatric patients presenting to a high secure hospital.
Can internal control activities and managerial conduct influence business sustainability? A South African SMME perspective
Authors: Bruwer Juan-Pierré , Coetzee Philna , Meiring Jacolize 
Published: July 2017

PurposeThe purpose of this paper is to determine the empirical relationships that exist between two of the elements of a sound internal control system, namely internal control activities and managerial conduct, and the perceived sustainability of South African small, medium and micro enterprises (SMMEs).Design/methodology/approachData were obtained from management and employees of 100 South African SMMEs operating in the Fast Moving Consumer Goods industry. All participants were interviewed by means of face-to-face structured interviews due to the complexity of the questions posed.FindingsOnly general management competencies have a relationship with the economic sustainability of these business entities. The rejection of three of the four hypotheses supports the current poor sustainability rate with approximately 75 per cent of South African SMMEs having to close their doors after being in operation for only three years.Originality/valueAs this study is the first of its kind for SMMEs, and although limited relationships were identified, it is crucial for management of SMMEs as well as government bodies that have an influence sphere over these entities, to ensure that SMME management incorporate crucial internal control activities and appropriate management conduct in their businesses.

Authors: Frolova Liliya , Pivovarov Alexander , Butyrina Tatyana 
Published: July 2017

Purpose
The purpose of this work is to study the patterns of pigment colour formation and to develop metal compositions for obtaining spinels using the precipitation and heat treatment methods.

Design/methodology/approach
Precursor materials were prepared using co-precipitation method. Phase composition of pigments were determined by X-ray diffraction. Colour of pigments was determined spectrophotometry. Modelling of colour formation was performed using simplex method. Planning in the future to carry out full synthesis of pigments of blue, red and yellow colours.

Findings
The paper deals with the results of theoretical and experimental research on the synthesis pigments of blue, red and yellow colours based on Fe-Co-Al-O spinel. The influence of the chromophore cation content and the heat treatment temperature on optical and colour characteristics of pigments were studied.

Originality/value
The resulting composition-property diagrams make it possible to evaluate the effect of chromophore cations and heat treatment on the colour formation for Fe2O3-Al2O3-CoO system. Crystal-phase composition of the pigments is installed and its relationship with the optical colour characteristics. That makes it possible carry out targeted synthesis of pigments blue, red and yellow colours in further. The phase composition of pigments and its relationship with optical and colour properties has been established thus enabling the directed synthesis of blue, red and yellow pigments.
Six Sigma in education
Authors: LeMahieu Paul G. , Nordstrum Lee E. , Cudney Elizabeth A. 
Published: July 2017

Purpose
This paper is one of seven in this volume that aims to elaborate different approaches to quality improvement in education. It delineates a methodology called Six Sigma.

Design/methodology/approach
The paper presents the origins, theoretical foundations, core principles and a case study demonstrating an application of Six Sigma in a school-community partnership in Milwaukee, Wisconsin.

Findings
The core principles underlying the approach are decreasing variability or unreliability in organizational work processes, eliminate waste or activity that does not add value to desired outcomes, identify defects and decrease their incidence, reduce the cost of work processes, and improve beneficiary/client satisfaction levels. The steps in this statistics-dependent method are design, measure, analyze, improve and control.

Originality/value
Few theoretical treatments and demonstration cases are currently available on commonly used models of quality improvement that might have potential value in improving education systems internationally. This paper fills this gap by elucidating one promising approach. The paper also derives value as it permits a comparison of the Six Sigma approach with other quality improvement approaches treated in this volume.
Incorporation of Cross‐Disciplinary Teaching and a Wiki Research Project to Engage Undergraduate Students’ to Develop Information Literacy, Critical Thinking, and Communication Skills
Authors: Crist Courtney A. , Duncan Susan E. , Bianchi Laurie M. 
Published: July 2017

AbstractA Wiki research project was created in the Functional Foods for Health (FST/HNFE 2544) as an instructional tool and assignment for improving undergraduate students’ proficiency in evaluating appropriate information sources for rapidly evolving science and research. The project design targeted improving students’ information literacy skills including how students obtain, discern relevant and reliable scientific information from propaganda, critique information, and communicate scientific language. In addition to the Wiki research project, guest experts in political science, statistics, and human nutrition discussed their expertise as related to functional foods to the class. A reviewer rubric was developed to evaluate and compare Wiki project assignments from the Fall 2013 course (experimental; cross‐disciplinary topics) with the previous course offering (control, Fall 2012; no cross‐disciplinary lectures) to establish a directionality of academic performance change between the 2 course years. Eight rubric criteria were categorized as critical thinking, cross‐discipline, and communication (scoring: 1 [lowest] and 3 [highest]). We observed that the critical thinking criteria (n = 5) had improved scores (P < 0.05) from Fall 2012 to Fall 2013. Cross‐discipline criteria (n = 2) had one categorical improvement (P < 0.05) but one category did not have improved scores (P > 0.05) in the experimental year (Fall 2013) despite the multidiscipline guest lectures. This educational intervention provides value to instructors for incorporating critical thinking, information literacy, and communication assignments that encourage skill development and practice to improve student proficiency. Students felt their skills and knowledge increased based on this project. This manuscript provides assignment guidelines and teaching techniques used to assist in development and improvement of students’ critical thinking skills, communication, and information literacy.
