Leaping into public leadership
Authors: Nahavandi Afsaneh , Corbett Lyn 
Published: August 2018

PurposeThe purpose of this paper is to explore the reasons for and consequences of leaders moving from other sectors to the public arena and provide guidelines for successful transitions to the public sector.Design/methodology/approachThe paper relies on a conceptual analysis of leadership theory, critical reasoning and several examples to explore the phenomenon the authors call Leadership Leap (LL).FindingsThe paper explores the context, antecedents, causes and consequences of LL. The leaders’ self-confidence, ego and hubris are often considered to be the reason for leaping to an unfamiliar sector; however, the causes are much more complex. The authors suggest that in addition to the leaders’ personal characteristics, LL is encouraged by a culture of celebrity, excessive focus on the leaders and a longing for heroes. Ignoring or disregarding the context and overestimating the need for revolutionary change further exacerbate LL. The authors consider conditions for success and suggest areas for future research.Originality/valueWe are increasingly witnessing leaders who are successful and considered experts in one sector transition into the public sector. Although some are successful, others face obstacles and fail to live up to expectations. The unique characteristics of public leadership, specifically the collective nature of the sector and the crucial role of context and systems, provide a particular challenge for LL in the sector.
Inter-linkages between remittance and savings in Ghana
Authors: Quartey Peter , Ackah Charles , Lambon-Quayefio Monica Puoma 
Published: August 2018

PurposeThe increase in volumes and circulation of internal and international remittances have become a substantial part of resource flow for economic development especially in developing countries with a significant impact on household welfare. The purpose of this paper is to examine the relationship between remittances and savings mobilization.Design/methodology/approachUsing the most recent wave of the Ghana Living Standard Survey data, the study accounts for the endogeneity in remittance receipts by employing treatment effect estimators, in addition to a probit model to establish the relationship between remittances and likelihood of savings.FindingsThe results suggest that receiving remittances significantly affects household’s propensity to save. Households that receive international remittances seem to have a slightly higher probability of savings compared to households that receive only domestic remittances.Originality/valueFrom the literature, whereas the theoretical relationship between savings and remittances is mixed, it is also evident that the empirical relationship between remittances and savings has not been clearly established, especially in sub-Saharan African countries in general and Ghana in particular. The present study adds to the paucity in the literature in two main ways. First, the study provides empirical evidence on the relationship between remittances and savings by not only focusing on international remittances but also on internal remittances. Second, in sharp departure from other studies, the current study employs more robust empirical estimators in estimating the relationship between remittances and savings.

Authors: Chuangui Yang , Xingbao Liu , Xiaobin Yue , Liang Mi , Junwen Wang , Yangqiu Xia , Hailian Yu , Heng Chen 
Published: August 2018

Purpose
This paper aims to solve the nonlinear problem in the uncertainty evaluation of the measurement of the positioning repeatability (RP) of industrial robots and provide guidance to restrict the uncertainty of measurement of RP (uRP).

Design/methodology/approach
Firstly, some uncertain sources existing in the measurement procedure of RP are identified. Secondly, the probability distribution function (PDF) of every source is established on the basis of its measurements. Some spatial combined normal distributions are adopted. Then, a method, based on Monte Carlo method (MCM) and established measurement model, is developed for the estimation of uRP. Thirdly, some tests are developed for the identification and validation of the selected PDFs of uncertain sources. Afterwards, the proposed method is applied for the evaluation and validation of the uRP. Finally, influence analyses of some key factors are proposed for the quantification of their relative contributions to uRP.

Findings
Results show that the proposed method can reasonably and objectively estimate the uRP of the selected industrial robot, and changes of the industrial robots’ position and the laser trackers measurement are correlated. Additionally, the uRP of the selected industrial robot can be restricted by using the results of its key factors on uRP.

Originality/value
This paper proposes the spatial combined normal distribution to model the uncertainty of the repeatability of the laser tracker and industrial robot. Meanwhile, the proposed method and influence analyses can be used in estimating and restricting the uRP and thus useful in determining whether the RP of a tested industrial robot meets its requirements.
The contribution of ICT adoption to sustainability: households’ perspective
Authors: Ziemba Ewa 
Published: August 2018

Purpose
The purpose of this paper is to advance the information society research by examining and better understanding the impact of the adoption information and communication technologies (ICT) within households on improving sustainability.

Design/methodology/approach
The survey questionnaire was used and data collected from 679 Polish households were statistically analyzed to understand the phenomena of ICT adoption and sustainability as well as identify correlations between them.

Findings
The research findings reveal that the ICT adoption is well described by the ICT outlay, information culture, ICT management and ICT quality, whereas sustainability is composed of ecological, economic, socio-cultural and political sustainability. Furthermore, the ICT quality, ICT management and information culture have a significant impact on sustainability, whereas the ICT outlay does not have such an impact.

Research limitations/implications
The research sample included Polish households only. Researchers may use the proposed approach and methodology to do similar analyses with different sample groups in other countries.

Practical implications
Households may find the results appealing and useful in enhancing the adoption of ICT, experiencing the full potential of ICT and deriving various benefits from the ICT adoption. The findings can help governments develop sound ICT adoption plans for implementing the 2030 Agenda for Sustainable Development.

Originality/value
The paper provides and verifies a new theoretical model of sustainable information society to depict various dimensions shaping the ICT adoption and their impact on different types of sustainability in the context of households.
Using k-means clustering in international location decision
Authors: Khalid Waqas , Herbert-Hansen Zaza Nadja Lee 
Published: August 2018

Purpose
This paper aims to investigate the application of unsupervised machine learning in the international location decision (ILD). This paper addresses the need for a fast, quantitative and dynamic location decision framework.

Design/methodology/approach
Unsupervised machine learning technique, i.e. k-means clustering, is used to carry out the analysis. In total, 24 different indicators of 94 countries, categorized into five groups, have been used in the analysis. After the clustering, the clusters have been compared and scored to select the feasible countries.

Findings
A new framework is developed based on k-means clustering that can be used in ILD. This method provides a quantitative output without personal subjectivity. The indicators can be easily added or extracted based on the preferences of the decision-makers. Hence, it was found out that the unsupervised machine learning, i.e. k-means clustering, is a fast and flexible decision support framework that can be used in ILD.

Research limitations/implications
Limitations include the generality of selected indicators and clustering algorithm used. The use of other methods and parameters may lead to alternate results.

Originality/value
The framework developed through the research intends to assist the decision-makers in deciding on the facility locations. The framework can be used in international and national domains. It provides a quantitative, fast and flexible way to shortlist the potential locations. Other methods can also be used to further decide on the specific location.

Published: August 2018

PurposeThe purpose of this paper is to analyze the relationship between Job Design, Job Commitment and Organizational Culture with Human Resource Performance: a study of the construction services provided by national consultants.Design/methodology/approachThe research population consisted of all employees of a national company offering consultation services, from four big Indonesian State-Owned Enterprises Contractors: PT. Yodya Karya Company, PT. Hutama Karya, PT. Adhy Karya, PT. Waskita Karya Referring to the approach to SEM modeling with an average population of 600 employees for each enterprises, the sample to be used as respondents consisted of 100 employees for each enterprises, and total 100×4 enterprises=400 samples.FindingsThe variables Organizational Culture and Job Design have a significant direct effect on Job Commitment. Likewise, the effect of Organizational Culture and Job Commitment on Human Resource Performance is also significant. However, a different result is shown in the result of the direct effect of the variable Job Design on the variable Human Resource Performance, which indicates that the variable Job Design does not have a significant direct effect on the variable Human Resource Performance. In other words, the intensity of the Job Design value will not affect the intensity level of Human Resource Performance. In addition, a mediating effect of the variable Job Commitment is found on the effect of Job Design and Organizational Culture on Human Resource Performance.Originality/valueThe use of Job Commitment to exercise a mediation effect on the relationship between the effect of Job Design and Organizational Culture on Human Resource Performance, and the research site (no previous research investigating this relationship).

Authors: Ortiz-Barrios Miguel Angel , Herrera-Fontalvo Zulmeira , Rúa-Muñoz Javier , Ojeda-Gutiérrez Saimon , De Felice Fabio , Petrillo Antonella 
Published: August 2018

Purpose
The risk of adverse events in a hospital evaluation is an important process in healthcare management. It involves several technical, social, and economical aspects. The purpose of this paper is to propose an integrated approach to evaluate the risk of adverse events in the hospital sector.

Design/methodology/approach
This paper aims to provide a decision-making framework to evaluate hospital service. Three well-known methods are applied. More specifically are proposed the following methods: analytic hierarchy process (AHP), a structured technique for organizing and analyzing complex decisions, based on mathematics and psychology developed by Thomas L. Saaty in the 1970s; decision-making trial and evaluation laboratory (DEMATEL) to construct interrelations between criteria/factors and VIKOR method, a commonly used multiple-criteria decision analysis technique for determining a compromise solution and improving the quality of decision making.

Findings
The example provided has demonstrated that the proposed approach is an effective and useful tool to assess the risk of adverse events in the hospital sector. The results could help the hospital identify its high performance level and take appropriate measures in advance to prevent adverse events. The authors can conclude that the promising results obtained in applying the AHP–DEMATEL–VIKOR method suggest that the hybrid method can be used to create decision aids that it simplifies the shared decision-making process.

Originality/value
This paper presents a novel approach based on the integration of AHP, DEMATEL and VIKOR methods. The final aim is to propose a robust methodology to overcome disadvantages associated with each method.
A three-stage dynamic model of financial distress
Authors: Farooq Umar , Jibran Qamar Muhammad Ali , Haque Abdul 
Published: August 2018

Purpose
The purpose of this paper is to explain the multi-stage dynamic process of financial distress. An attempt is made to explore multiple adverse heterogeneous events of financial distress leading a firm closer to bankruptcy progressively.

Design/methodology/approach
Sample comprises 321 ongoing, 54 suspended and 91 delisted non-financial firms from Pakistan Stock Exchange. Financial distress is segregated into three stages, i.e. profit reduction, mild liquidity (ML) and severe liquidity (SL). Flow diagrams are used to explain the transition of healthy firms through proposed stages of financial distress.

Findings
Results showed that firms liquidated/winding-up by court documented SL problems and closed their operations well before the delisting year. It is found that healthy firms are more likely to face SL when faced ML problem at first stage. Distressed firms can recover to a healthy position at any stage, however after approaching to SL, recovery is less expected.

Practical implications
The proposed process will provide a foundation for future studies to develop more relevant, robust and accurate early warning system of corporate failure that will help stakeholders to respond potential crisis accordingly and timely.

Originality/value
Previously, most of the studies used the ex post definition of bankruptcy that is criticized due to the contextual application, sample bias and non-segregation by the degree of liquidity problems. The originality of the proposed ex ante model is its segregation into a three-stage process that can be generalized regardless of specific bankruptcy law.
The effect of TiO2 nanoparticles on color of cotton fabric dyed with reactive dye
Authors: Nateri A. Shams , Zandi Sheida , Motaghitalab Vahid , Piri Negin 
Published: August 2018

Purpose
This paper aims to investigate the effect of titanium dioxide (TiO2) nanoparticle coating on the visible reflectance and color appearance of dyed cotton fabrics.

Design/methodology/approach
A Taguchi experimental design model was used to minimize the number of samples and for accurate prediction of possible responses. The governing parameters affecting the color change of dyed fabrics through the coating process were selected as shade of cotton fabrics, depth of shade, concentration and size of TiO2 nanoparticles and concentration of citric acid. The Taguchi model suggests the L18 orthogonal array. In the meantime, the lower response category was selected to determine the optimum conditions. According to obtained results, coating with TiO2 nanoparticles results in color change (ΔEab*) of all dyed cotton fabrics.

Findings
The obtained results indicate that the TiO2-coated fabrics had higher reflectance compared to raw fabrics. Furthermore, it was found that the TiO2 pigmented coating increases the brightness of samples and simultaneously decreases their chroma. On the other hand, analysis of variance reveals that the concentration of TiO2 nanoparticles together with shade of fabrics has the most significant impact on the color change of dyed fabrics through coating process. Dye concentration and size of TiO2 particles also, to the same extent, had influence over the color change. However, the effect of the concentration of citric acid on the color change was insignificant.

Originality/value
This research investigates the effect of TiO2 nanoparticles on the optical property of colored fabric by using a Taguchi experimental design model to minimize the number of samples.
Managerial equity incentives and anti-dilutive convertible debt decisions
Authors: Akono Henri 
Published: August 2018

PurposeThis paper aims to examine whether high equity incentives motivate executives to avoid issuing convertible debt and/or to design convertible debt issues as anti-dilutive to earnings-per-share (EPS).Design/methodology/approachTests are conducted using the Heckman two-step probit model to control for potential self-selection bias between firms that issue straight debt and those that issue convertible debt. Further, analyses are conducted separately and jointly for the Chief Executive Officer (CEO) and the Chief Financial Officer (CFO) to assess the differential impact of CEOs’ and CFOs’ equity incentives on convertible debt issuance and design decisions.FindingsFirms are more likely to design convertible debt issues as anti-dilutive to EPS when CFOs have high levels of equity incentives, but only when the firm stock price is sensitive to diluted EPS. High CEOs’ equity incentives have limited impact of convertible debt issuance and design decisions.Research limitations/implicationsThe main limitation of this study is the generalizability of the findings and implications of this study due to the smaller sample size of convertible debt issues.Originality/valuePrior research has shown that bonus incentives influence CEOs with disincentive for EPS dilution and motivate them to make anti-dilutive financing decisions. Further, there is evidence that high equity incentives motivate CEOs to manage earnings to boost short-term prices. This study extends prior literature by showing that high equity incentives provide executives with disincentive for EPS dilution and motivate CFOs to design convertible debt issues as anti-dilutive to EPS possibly to avoid reduced stock prices. Further, this study shows that CFOs have greater influence over convertible debt design choices than CEOs do.
Development and characterization of a high-sensitivity fiber Bragg grating-based vibrating nano-probe for 3D measurement
Authors: Liu Fangfang , Wang Jingfan , Chen Lijuan , Li Ruijun , Xia Haojie , Yu Liandong 
Published: August 2018

Purpose
There is an increasing demand for higher-accuracy dimensional measurements of nano- and micro-structures. Recently, the authors presented a fiber Bragg grating (FBG) sensor-based dynamic nano-coordinate-measuring machine (CMM) probe for true three-dimensional coordinate measurement, in which a specific mechanical structure with several FBG sensors was developed to provide the probe with sensitivity to loading in all directions.

Design/methodology/approach
The study presents a three-dimensional sensing and demodulation system based on an improved matched filter design and the time division multiplexing technique that helps solve the problem of multiplex FBG-signals conflicts. In addition, the application of the dynamic mode of the probe system effectively solves the problem presented by the surface interaction forces.

Findings
Consequently, this FBG-based vibrating probe system has increased sensitivity to strain, while maintaining smaller contact force. The experiments for testing probe performance show that the prototype yielded a measurement resolution of 13 nm, a repeatability of 50 nm and a vertical measurement force of less than1.5 mN.

Research limitations/implications
The force tests in the horizontal directions are difficult to conduct because both the probe and the dynamometer are only adaptable to vertical use.

Practical implications
Development of the FBG-based dynamic nano-coordinate-measuring machine probe will achieve a new and inexpensive method for higher-accuracy dimensional measurements of nano- and micro-structures, such as micro-electromechanical systems, micro-fluidic chips, inkjet and diesel engine injector nozzles that are in overall dimensions within the micrometer scale.

Originality/value
The study presents a three-dimensional sensing and demodulation system for the vibrating nano-coordinate-measuring machine probe based on FBG sensors. The prototype yielded a measurement resolution of 13 nm, a repeatability of 50 nm and a vertical measurement force of less than1.5 mN.
Seven decades of mountain hare counts show severe declines where high‐yield recreational game bird hunting is practised
Authors: Watson Adam , Wilson Jeremy D. 
Published: August 2018

Abstract

Recreational hunting is widespread and can benefit nature conservation when well‐practised, monitored, and regulated. Management for recreational red grouse Lagopus lagopus scotica shooting on upland heathland in the UK causes conservation conflict because the intensive habitat, predator, and disease management needed to maintain high‐grouse densities for “driven” shooting has detrimental environmental impacts, notably for raptor populations.

Sustainable management of mountain hares Lepus timidus scoticus, a game species in the same landscapes, poses a challenge. Control of transmission to grouse of a viral disease, louping‐ill, for which mountain hares are a host, has become an additional motivation to kill mountain hares since research during 1993–2001 suggested that culls might reduce infection rates in grouse.

We analysed population trends of mountain hares from spring counts on moorland managed for grouse shooting and on contiguous alpine land. On moorland sites, a long‐term decline (4.6% per annum) from 1954 to 1999 increased to 30.7% per annum from then until 2017, with a density index falling to <1% of initial levels after 2008. Before 1999, declines were associated with conifer planting and were least severe where heather burning characteristic of grouse management was present. Grouse moors had the highest rate of decline after 1999.

On alpine sites, the density index increased by 2.0% per annum from 1954 to 2007, then declined by 12.3% per annum but remained within the previous range of variation.

Despite lack of evidence that it increases grouse numbers, reduction of louping‐ill transmission to grouse became a more frequent justification for mountain hare culls at a time consistent with it causing these recent, rapid mountain hare declines on grouse moors.

Synthesis and applications. Long‐term field counts suggest that intensification of game bird management has resulted in severe, recent declines in mountain hare numbers, exacerbating longer term declines associated with land‐use change. Management practices founded on misinterpretation of earlier research are the probable cause. Regulation of hare culling would provide a framework for formal tests of whether culls affect grouse surpluses. It would also provide an opportunity to examine mountain hare populations' resilience to culls of varying size and seasonal timing.
