Wear analysis of PVD-coated twist drills under MQL
Authors: Cardoso Marlon José , Polli Milton Luiz , Pintaude Giuseppe 
Published: October 2018

Purpose
Deep drilling of hardened steels is a difficult machining operation because of the high wear level of tools. This paper aims to present the main wear mechanisms observed in physical vapor deposition (PVD)-coated twist drills during deep drilling of SAE4144M steel under minimum quantity lubrication, assessed in the production of injection holders.

Design/methodology/approach
Two PVD coatings were tested: TiAlN and AlCrN, industrially processed, the last one being a multilayer coating. The workpiece was heat treated for a hardness of 39 HRC to be applied in a diesel engine component. The tests were performed in an industrial environment for a fixed number of holes. Two levels of cutting speed and feed rate were selected for the experiments. In addition, minimum quantity of lubrication (MQL) was compared with conventional lubrication. Scanning electron microscope was used to reveal the wear mechanisms.

Findings
Spalling of PVD-coating was revealed for conventional lubrication, while adhesion was observed in MQL conditions. The use of multilayered AlCrN-based coating promoted a significant reduction of adhered material on the twist drill, which is the reason for this selection in industrial operation.

Practical implications
Results showed that the MQL regime can be applied for this industrial application.

Originality/value
A detailed description of wear mechanisms, which allows a suitable selection of coating and machining variables was found for a very difficult operation, using a more economic process in terms of lubrication.
Development and analysis of DAYANI arc contour intelligent technique for navigation of two-wheeled mobile robot
Authors: Parhi Dayal R. , Chhotray Animesh 
Published: October 2018

Purpose
This paper aims to generate an obstacle free real time optimal path in a cluttered environment for a two-wheeled mobile robot (TWMR).

Design/methodology/approach
This TWMR resembles an inverted pendulum having an intermediate body mounted on a robotic mobile platform with two wheels driven by two DC motors separately. In this article, a novel motion planning strategy named as DAYANI arc contour intelligent technique has been proposed for navigation of the two-wheeled self-balancing robot in a global environment populated by obstacles. The developed new path planning algorithm evaluates the best next feasible point of motion considering five weight functions from an arc contour depending upon five separate navigational parameters.

Findings
Authenticity of the proposed navigational algorithm has been demonstrated by computing the path length and time taken through a series of simulations and experimental verifications and the average percentage of error is found to be about 6%.

Practical implications
This robot dynamically stabilizes itself with taller configuration, can spin on the spot and rove along through obstacles with smaller footprints. This diversifies its areas of application to both indoor and outdoor environments especially with very narrow spaces, sharp turns and inclined surfaces where its multi-wheel counterparts feel difficult to perform.

Originality/value
A new obstacle avoidance and path planning algorithm through incremental step advancement by evaluating the best next feasible point of motion has been established and verified through both experiment and simulation.
Moderating role of gender amongst various constructs of CRM
Authors: Maggon Mohita , Chaudhry Harish 
Published: October 2018

PurposeThe purpose of this paper is to examine the interrelationships among the extracted constructs of customer satisfaction (CS), knowledge about customer relationship management (CRM) program, customer attitude and their effect on relationship share (RS). The study also attempts to find if moderating role of gender exists among these constructs.Design/methodology/approachA conceptual framework is developed based on previous studies. In order to address a lack of comprehensive evaluation of B2C relationships in Indian hotels, this study extracted the dimensions of CRM in hotels and used them in the structural model. The conceptual model is tested using structural equation modeling approach through maximum likelihood estimation technique. A sample of 305 domestic travelers was used to test the hypothesized relationships among the constructs.FindingsThe findings indicate that CS and willingness to engage (CWER) in the relationship are major predictors of RS. Besides, CS indirectly affects RS through customer’s attitude toward the hotel. The results of the study also show that customer willingness to engage in the relationship is dependent on attitude of customer toward firm which is further dependent on knowledge about CRM program. One more notable finding of the study states that gender plays a moderating role between CS and customer willingness to engage in the relationship.Practical implicationsIn addition to contributing toward academic knowledge, the findings of the present study will help the practitioners to better design CRM program and reap its maximum benefits.Originality/valueThe current study has considered new dimensions of CRM like customer’s knowledge of CRM and this is the first study to capture responses of Indian travelers in relation with various constructs. This is the first study to test the moderating effect of gender between various constructs.
Making change last: leadership is the key
Authors: Page Lesley , Schoder Jacquie 
Published: October 2018

Purpose
Multiple models of organizational change provide guidance, goals and strategic steps for organizations to complete initiatives effectively. The purpose of this paper was to discuss the impact of transformational leadership as it relates to organizational change in the twenty-first century and propose a consolidated approach to planned organizational change useful for practitioners.

Design/methodology/approach
Practitioners and researchers can benefit by a strategy to apply models of change to organizational initiatives. It is proposed that models by Kotter (2012), Bridges (2017) and Lewin (1951) can be consolidated into a comprehensive approach to achieve successful organizational change. Transformational leadership is a critical component which bonds such models together and guides the leader’s role in the process.

Findings
Kotter, Bridges and Lewin’s approaches all share similar beliefs about the effectiveness of a transformational leader. First, people and process aspects of change take center stage. Second, urgency needs to unsettle or awaken the need for change. Third, people want to be part of the change process. By involving others, engagement, empowerment and buy-in all increase. Fourth, change will only last if it is embedded into the structures and systems which make up the organization’s culture.

Originality/value
The value of the consolidated approach to change proposed in this paper is that it meets leaders at their level of skill and experience, as it offers options depending on the needs of the organization and extent (depth) of the change required.
University spin-offs creation in the Latin American region
Authors: Montiel-Campos Héctor 
Published: October 2018

Purpose
This paper aims to empirically explore the influence that different factors have on the creation of university spin-offs.

Design/methodology/approach
This is an exploratory study that uses a multilevel design. The study follows a purposive sampling method where data are gathered from a variety of sources. The hypotheses are tested with a sample of 52 universities from the Latin American region using multiple hierarchical regression analysis.

Findings
The results indicate that entrepreneurial orientation, incubators or entrepreneurship support programs and goods market efficiency are the factors that positively influence the creation of university spin-offs.

Research limitations/implications
The results of this study should be observed in light of some limitations. The sample size is an important factor, as a bigger sample could allow for examination of cross-institutional variation in the context of different countries. In addition, the lack of records or public databases makes it difficult to incorporate more information on spin-offs creation, including features or firm performance.

Originality/value
This study is the first to empirically explore the university spin-offs creation phenomenon in the Latin American region. Hence, it contributes to university entrepreneurship literature, specifically to better understand this phenomenon from a more holistic perspective across different levels of analysis at the same time that it incorporates previous proposals to explain entrepreneurial orientation at universities.
Understanding the intentions of informal entrepreneurs in Peru
Authors: Amésquita Cubillas Fidel , Morales Oswaldo , Rees Gareth H. 
Published: October 2018

PurposeThis paper aims to focus on the influences that lead individuals to create and continue with operating informal business ventures in Peru. It seeks to empirically identify the factors that are significant in forming the intentions of entrepreneurs to begin or continue with their informal businesses.Design/methodology/approachThe theory of planned behaviour (TPB) is applied using data gathered from interviews with informal domestic gas cylinder sellers using a formally conducted survey. Using structural equation modelling, the constructs that influence the entrepreneurial intentions of informal gas sellers in Lima, Peru, are determined.FindingsOf the three TPB constructs, attitude was found to be most significant, reflecting a belief of informality’s benefits, social norm was also significant, revealing the importance of the opinions of family, whereas perceived behavioural control was found not to be significant.Originality/valueThese results provide confirmation of a policy approach developed to address the high rates of business informality while maintaining safety in a highly regulated industry segment. By providing insight into factors beyond economic drivers, the study reveals that an understanding of the prevailing social environment is important for the development of policies dealing with informal entrepreneurship.

Authors: Stowell Nicole F. , Schmidt Martina , Wadlinger Nathan 
Published: October 2018

Purpose
The purpose of this paper is to make readers aware of the extensiveness of healthcare fraud in the USA and how it involves and affects the government, healthcare providers, insurance companies, patients and the public. In addition, recommendations are made that may help control this pervasive type of fraud.

Design/methodology/approach
A range of different journal publications, information from government health institutions and law enforcement websites, healthcare fraud cases and healthcare laws are used as a basis to provide information about how fraudsters are committing healthcare fraud and how to prevent this fraud from occurring.

Findings
Despite increased funding and prosecution efforts by the government, healthcare fraud continues to be a major threat to the US economy and public. While healthcare fraud will never be eradicated, specific efforts can be deployed to help rein in these complex fraud schemes.

Practical implications
The paper provides a useful resource of information on healthcare fraud for healthcare providers, insurance companies, patients and the public that may help combat healthcare fraud and prevent financial losses.

Social implications
Every dollar saved from combating fraud could be used to improve access to more or better health services and can, thereby, save lives.

Originality/value
This paper provides recommendations regarding healthcare fraud that could help prevent this large drain on the US economy.
A cross-cultural study of staying reasons of American brands
Authors: Saeed Munazza , Azmi Ilhaamie Abdul Ghani 
Published: October 2018

PurposeAlthough researchers have investigated thoroughly the consumer’s brand switching behaviour, the probability of confusion regarding “brand switching” is a less travelled road so far. Therefore, the purpose of current study is to investigate and highlight the underlying convincing parameters in relation to not switching from American brands within the context of millennial Muslim consumers in Pakistan and Malaysia.Design/methodology/approachData were collected from 704 consumers living in two divergent cultures, who were asked about American brands. Two categories of “reasons to stay” were examined: switching barriers and affirmatory factors.FindingsThe main discovery was that staying reasons for specific brands could be different in two different cultures, but they influence the ultimate brand switching behaviour.Practical implicationsThis study is important for those firms who have many prospective switchers because it is important to understand why these customers stay and discover to what extent such firms can discourage such consumers from leaving, in both positive and negative ways.Originality/valueThis is the first paper of its kind that examines the brand switching behaviour of millennial Muslim consumers.
Weighing the odds: an exploration of resistance to obesity and overweight
Authors: Conroy Denise , Smith Sandra D. , Frethey-Bentham Catherine 
Published: October 2018

PurposeIn 2018, we have surpassed the population landmark of 7.5 billion, and yesterday’s global crisis of under-nutrition in poorer nations is now accompanied by a journey into overweight and obesity. The purpose of our research is to focus on the health and resistance of those who avoid overweight and obesity rather than continuing to focus on the pathology and disease of this phenomenon.Design/methodology/approachTaking a consumer-centric perspective and using the lens of the social-economic framework, the authors report qualitative research conducted with 31 young people (ages 17-26) who have been resistant to weight gain in an increasingly obesogenic environment, followed by a survey of the general population,n= 921. The authors look at this type of consumer resistance to better understand how to develop government and community leadership and build more obesogenically resilient societies.FindingsThe findings support the contention that obesity is a social problem that requires a social solution.Originality/valueThe main contribution to the conversation addressing increasing levels of overweight and obesity is that this research demonstrates that these are complex social problems and require complex intervention at the societal level, not the individual level.
Knowledge management practices and innovation performance
Authors: Susanty Ade Irma , Yuningsih Yuyu , Anggadwita Grisna 
Published: October 2018

Purpose
This paper aims to concentrate on the conscious and systematic managerial activities associated with handling knowledge in an organization [i.e. knowledge management (KM) practices] for the purpose of improving innovation performance through proactive management of knowledge assets. This study explores the impact of KM practices on innovation performance in the research and training center of government apparatus.

Design/methodology/approach
This research provides empirical evidence on how various KM practices influence innovation performance. The results are based on the survey data collected in four areas of research and training centers of government apparatuses in Indonesia. Partial least squares are used to test the hypothesized relationships between KM practices and innovation performance.

Findings
The study found that IT practices and work organizations are positively and significantly related to innovation performance. This means that better implementation of information and technology will push innovation performance. The study also points out that knowledge-based compensation practice is one of the KM practice variables which is negatively and significantly related to innovation performance. This result shows that innovation performance will decrease by compensating knowledge improvement.

Practical implications
This study implies that in developing innovation performance, the research and training center should not focus on providing compensation, as it will only increase the costs rather than the innovation performance itself.

Originality/value
This study adds a knowledge-based view of government agencies by demonstrating the significance of KM for innovation performance. This study is also valuable from a managerial perspective, as it highlights the most effective KM practice to improve organizational innovation performance.
A systemic and cybernetic perspective on causality, big data and social networks in tourism
Authors: Lloret-Climent Miguel , Montoyo Andrés , Gutierrez Yoan , Muñoz Guillena Rafael , Alonso Kristian 
Published: October 2018

PurposeThe purpose of this paper is to propose a mathematical model to determine invariant sets, set covering, orbits and, in particular, attractors in the set of tourism variables. Analysis was carried out based on an algorithm and applying an interpretation of chaos theory developed in the context of General Systems Theory and Big Data.Design/methodology/approachTourism is one of the most digitalized sectors of the economy, and social networks are an important source of data for information gathering. However, the high levels of redundant information on the Web and the appearance of contradictory opinions and facts produce undesirable effects that must be cross-checked against real data. This paper sets out the causal relationships associated with tourist flows to enable the formulation of appropriate strategies.FindingsThe results can be applied to numerous cases, for example, in the analysis of tourist flows, these findings can be used to determine whether the behaviour of certain groups affects that of other groups, as well as analysing tourist behaviour in terms of the most relevant variables.Originality/valueThe technique presented here breaks with the usual treatment of the tourism topics. Unlike statistical analyses that merely provide information on current data, the authors use orbit analysis to forecast, if attractors are found, the behaviour of tourist variables in the immediate future.
Modelling and analysis of complex products design based on supernetwork
Authors: Zhang Na , Yang Yu , Su Jiafu , Zheng Yujie 
Published: October 2018

PurposeBecause of the multiple design elements and complicated relationship among design elements of complex products design, it is tough for designers to systematically and dynamically express and manage the complex products design process.Design/methodology/approachTo solve these problems, a supernetwork model of complex products design is constructed and analyzed in this paper. First, the design elements (customer demands, design agents, product structures, design tasks and design resources) are identified and analyzed, then the sub-network of design elements are built. Based on this, a supernetwork model of complex products design is constructed with the analysis of the relationship among sub-networks. Second, some typical and physical characteristics (robustness, vulnerability, degree and betweenness) of the supernetwork were calculated to analyze the performance of supernetwork and the features of complex product design process.FindingsThe design process of a wind turbine is studied as a case to illustrate the approach in this paper. The supernetwork can provide more information about collaborative design process of wind turbine than traditional models. Moreover, it can help managers and designers to manage the collaborative design process and improve collaborative design efficiency of wind turbine.Originality/valueThe authors find a new method (complex network or supernetwork) to describe and analyze complex mechanical product design.
What comes next: understanding BIBFRAME
Authors: Steele Thomas D. 
Published: October 2018

PurposeBibliographic framework initiative (BIBFRAME) is a data model created by the Library of Congress to with the long-term goal of replacing Machine Readable Cataloging (MARC). The purpose of this paper is to inform catalogers and other library professionals why MARC is lacking in the needs of current users, and how BIBFRAME works better to meet these needs. It will also explain linked data and the principles of Resource Description Framework, so catalogers will have a better understanding of BIBFRAME’s basic goals.Design/methodology/approachThe review of recent literature in print and online, as well as using the BIBFRAME editor to create a BIBFRAME record, was the basis for this paper.FindingsThe paper concludes the user experience with the library catalog has changed and requires more in-depth search capabilities using linked data and that BIBFRAME is a first step in meeting the user needs of the future.Originality/valueThe paper gives the reader an entry point into the complicated future catalogers and other professionals may feel trepidation about. With a systematic walkthrough of the creation of a BIBFRAME record, the reader should feel more informed where the future of cataloging is going.
Three-dimensional scanning and printing techniques to analyze and archive human skeletal remains
Authors: Henson Kristy , Constantino Paul , O’Keefe F. Robin , Popovich Greg 
Published: October 2018

PurposeThe topic of human skeletal analysis is a sensitive subject in North America. Laws and regulations surrounding research of human skeletal material make it difficult to use these remains to characterize various populations. Recent technology has the potential to solve this dilemma. Three-dimensional (3D) scanning creates virtual models of this material, and stores the information, allowing future studies on the material. The paper aims to discuss these issues.Design/methodology/approachTo assess the potential of this methodology, the authors compared processing time, accuracy and costs of computer tomography (CT) scanner to the Artec Eva portable 3D surface scanner. Using both methodologies the authors scanned and 3D printed one adult individual. The authors hypothesize that the Artec Eva will create digital replicas of <5 percent error based on Buikstra and Ubelaker standard osteometric measurements. Error was tested by comparing the measurements of the skeletal material to the Artec data, CT data and 3D printed data.FindingsResults show that larger bones recorded by the Artec Eva have <5 percent error of the original specimen while smaller more detailed images have >5 percent error. The CT images are closer to <5 percent accuracy, with few bones still >5 percent error. The Artec Eva scanner is inexpensive in comparison to a CT machine, but takes twice as long to process the Eva’s data. The Artec Eva is sufficient in replication of larger elements, but the CT machine is still a preferable means of skeletal replication, particularly for small elements.Originality/valueThis research paper is unique because it compares two common forms of digitization, which has not been done. The authors believe this paper would be of value to natural history curators and various researchers.
