A novel motion generation strategy for robotic tooth brushing simulator
Authors: Liu Jie 
Published: June 2013

PurposeThe purpose of this paper is to develop a robotic tooth brushing simulator mimicking realistic tooth brushing motions, thereby facilitating greater understanding of the generation of realistic tooth brushing motion for optimal design of toothbrushes.Design/methodology/approachTooth brushing motions were measured via a motion capture system. Different motion patterns of brushing were analysed. A series of elliptical motion segments were generated by interpolating ellipse‐like trajectories. Furthermore, a path generation algorithm for brushing simulation was proposed. A path planning system incorporating robot motion control was developed to simulate realistic tooth brushing. The generality and efficiency of the proposed algorithm was demonstrated through simulation and experimental results.FindingsThe interpolation of ellipse‐like trajectories can generate elliptical motion segments. Furthermore, realistic tooth brushing can be achieved by integrating the elliptical motion segments into the path generated from the surfaces of teeth. The brushing simulator demonstrated good reproducibility of clinically standardized tooth brushing.Practical implicationsA robotic toothbrush assessment system is a potential application to the robotic tooth brushing simulator by incorporating control of brushing variables, including brushing pressure, speed and temperature.Originality/valueThis study demonstrates the feasibility of using robotic simulation techniques towards improved realistic human tooth brushing motions simulation for optimal design of tooth brushes.
Development of an underwater riser inspection robot
Authors: Santos Melquisedec F. , Brito Maurício O. , Neves Cassiano , Menegaldo Luciano L. 
Published: June 2013

PurposeThe purpose of this paper is to describe a new multi‐sensor robotic system designed for riser, mooring lines and umbilical cables in situ underwater inspection. Due to the aggressive operation environment, such structures are susceptible to a broad spectrum of failure causes, such as aging, mechanical, chemical and thermal loads, hydrodynamic stresses, vortex‐induced vibrations and installation or fabrication non‐conformities. Current inspection methods present major risks and inefficiencies, especially as deeper fields are being reached for exploitation.Design/methodology/approachThe SIRIS (In Situ Riser Inspection Robotic System) is designed to reconstruct the actual riser profile and perform non‐destructive tests. The robot is propelled by thrusters to scroll by the outside of the catenary riser. Mechanical, electronic hardware, image acquisition and software/firmware design are described here.FindingsSimulated data from an inertial measurement unit is fused with depth sensor measurements, using a Kalman filter to reconstruct the riser profile, with small localization errors. Laboratory and sheltered waters tests were successfully executed to assess robot subsystems' performance: imaging, leakage, displacement and easiness of operation.Research limitations/implicationsThe robot prototype is designed to operate down to 250 m deep, although the final goal is reaching 3,000 m. Tests offshore, in a real oil production platform, have not been performed up to this moment. In the present version, the robot must be coupled to the riser with the aid of a scuba diver.Practical implicationsThe robot is expected to allow non‐destructive testing in risers that cannot be performed nowadays with the existing tools. The inspecting procedure is easy to operate and does imply any kind of production stopping. More accurate assessment of the riser structural condition can allow extending its life span, thus avoiding early decommissioning.Social implicationsBetter assessment of actual riser facilities status will have great impact on reducing the chance of oil spill episodes and serious environment damage.Originality/valueThe design, construction and evaluation of a robotic tool for non‐destructive riser inspection has been described. A few similar robots exist in literature but none of them is able to reconstruct the actual riser profile.

Authors: Bolton Ruth N. , Parasuraman A. , Hoefnagels Ankie , Migchels Nanne , Kabadayi Sertan , Gruber Thorsten , Komarova Loureiro Yuliya , Solnet David 
Published: June 2013

PurposeThe purpose of this paper is to review what we know – and don't know – about Generation Y's use of social media and to assess the implications for individuals, firms and society.Design/methodology/approachThe paper distinguishes Generation Y from other cohorts in terms of systematic differences in values, preferences and behavior that are stable over time (as opposed to maturational or other differences). It describes their social media use and highlights evidence of intra‐generational variance arising from environmental factors (including economic, cultural, technological and political/legal factors) and individual factors. Individual factors include stable factors (including socio‐economic status, age and lifecycle stage) and dynamic, endogenous factors (including goals, emotions, and social norms).The paper discusses how Generation Y's use of social media influences individuals, firms and society. It develops managerial implications and a research agenda.FindingsPrior research on the social media use of Generation Y raises more questions than it answers. It: focuses primarily on the USA and/or (at most) one other country, ignoring other regions with large and fast‐growing Generation Y populations where social‐media use and its determinants may differ significantly; tends to study students whose behaviors may change over their life cycle stages; relies on self‐reports by different age groups to infer Generation Y's social media use; and does not examine the drivers and outcomes of social‐media use. This paper's conceptual framework yields a detailed set of research questions.Originality/valueThis paper provides a conceptual framework for considering the antecedents and consequences of Generation Y's social media usage. It identifies unanswered questions about Generation Y's use of social media, as well as practical insights for managers.

Authors: van Riel Allard C.R. , Calabretta Giulia , Driessen Paul H. , Hillebrand Bas , Humphreys Ashlee , Krafft Manfred , Beckers Sander F.M. 
Published: June 2013

PurposeThe purpose of this paper is to investigate how the service constellation perspective affects innovation strategies and potentially contributes to the innovation literature, proposing a research agenda.Design/methodology/approachBy analyzing the notion of a service constellation, the authors provide an overview of major implications for service innovation research and practice.FindingsFirms and service innovation researchers need to focus on the perceived consumer value of the constellation rather than on individual services. The authors illustrate how service innovation from the constellation perspective requires coordination and synchronization between projects and different approaches to portfolio management and screening.Originality/valueAdoption of the service constellation perspective creates new opportunities.
Communication technologies promoting educational communities with scholarship of engagement
Authors: Georgakopoulos Alexia , Hawkins Steven T. 
Published: June 2013

PurposeThis study aims to present Dramatic Problem Solving Facilitation Model (DPSFM) and Interactive Management (IM) as innovative alternative dispute resolution approaches that incorporate communication technologies in recording and analyzing data. DPSFM utilizes performance‐based actions with facilitation methods to help participants design action plans. Interactive Management (IM) utilizes a holistic, culturally sensitive and systemic approach to resolve complex problems. Communication technological assistance is accompanied by IM to enhance parsimony and support saliency of the ideas generated. Both approaches support action plans. This paper argues that both DPSFM and IM are theoretical frameworks that are valuable for conflict resolution, educators, and social science specialists who are interested in conducting research under the paradigm of knowing referred to as “Scholarship of Engagement”. This paradigm engages participants in research while promoting action plans and improving status quo conditions. The current paper overviews the benefits of both models and makes a strong case for application of their communication technologies across a variety of contexts. DPSFM and IM are directly involved with promoting change, and supporting actions to improve human conditions. The framework of “Scholarship of Engagement” is introduced as an integrative model for “praxis”. The purpose of this paper was to provide alternative options for working in facilitation groups.Design/methodology/approachThe methodological approach involved the models of DPSFM and IM.FindingsThe findings of DPSFM and IM applications have been positive and they were revealed in several domestic and international settings.Originality/valueThe value of this work is that it presents an alternative perspective to traditional models in facilitation. The work has transferability in a number of community settings.
International offshore students’ perceptions of virtual office hours
Authors: Wdowik Steven , Michael Kathy 
Published: June 2013

PurposeThe main aim of this study is to gauge international offshore students’ perceptions of virtual office hours (VOH) to consult with their offshore unit coordinators in Australia.Design/methodology/approachThis paper employs a quantitative and qualitative approach where data was sourced from three offshore campuses over a 12‐month period using a survey instrument. SPSS v20 was used to perform basic descriptive analysis, cross tabulations and chi‐square statistics.FindingsThe study revealed that 81 per cent of respondents indicated a willingness to use VOH. A number of perceived benefits of VOH were also identified, including support my learning, instant feedback, feeling valued and convenience.Research limitations/implicationsParticipants may have inaccurate perceptions which can manifest in misguided data being presented. The willingness by the majority of undergraduate offshore students to use computer‐mediated communication to conduct VOH provides a platform to explore new ways to promote out‐of‐classroom communication. Students may become more engaged in the teaching and learning process and ultimately provide a more enriched and quality experience.Originality/valueThis study addresses a distinctive gap in the existing literature relating to gauging international offshore students’ perceptions of VOH. Furthermore, the study adds richness to a relatively new trend amongst educators in exploring students’ perceptions of VOH.
ICT expenditures and education outputs/outcomes in selected developed countries
Authors: Aristovnik Aleksander 
Published: June 2013

PurposeThe aim of the paper is to review some previous researches examining ICT efficiency and the impact of ICT on educational output/outcome as well as different conceptual and methodological issues related to performance measurement.Design/methodology/approachThis paper adopts a non‐parametric methodology, i.e. data envelopment analysis (DEA) technique, and applies it to selected EU‐27 and OECD countries.FindingsThe empirical results of the varying levels of (output‐oriented) efficiency (under the VRSTE framework) show that Finland, Norway, Belgium and Korea are the most efficient countries in terms of their ICT sectors. In addition, the analysis also finds evidence that most of the countries under consideration hold great potential for increased efficiency in ICT and for improving their educational outputs and outcomes.Originality/valueThis is the first paper that investigates such a wide range of countries with DEA technique when analyzing efficiency of ICT sector from an educational perspective.
Learn from insurance: cyber bore
Authors: Mainelli Michael 
Published: June 2013

PurposeThe purpose of this paper is to look at how cyber insurance markets might work with the backing of government reinsurance.Design/methodology/approachThe paper is based on interviews and workshops on cyber security, cyber terrorism and cyber crime.FindingsThe paper links a successful 1990s' approach to property terrorism risk to helping address cyber risk.Originality/valueOf note, the author suggests that cyber risk is under control when organisations at risk can purchase normal insurances.
What is the driving force behind consolidations in the insurance market?
Authors: Okura Mahito , Yanase Noriyoshi 
Published: June 2013

PurposeThe purpose of this paper is to discuss whether insurers could have a strong motivation for M&A in the future because they need to survive within the industry under oversaturated market conditions. Recently, Japanese non‐life insurance markets, mainly the automobile insurance market, have reached the point of saturation due to the oversaturated domestic automobile market. At that time, the industry has also experienced successive large‐scale M&A transactions.Design/methodology/approachUsing a theoretical model developed by Salent et al., the authors discuss whether an insurer's motivation for M&A could be affected by a saturation of the market. The authors also clarify whether insurance premium deregulation is a necessary condition for merger incentives.FindingsThe authors conclude that, first, necessary requirement for insurers' motivation of consolidations is to loosen the rate regulation; and second, the sufficient condition is saturation of market.Research limitations/implicationsThis result is intuitive to understand recent circumstances surrounding the Japanese non‐life insurance industry.Originality/valueThis study is believed to be the first to discuss the relationship between a potential market size and M&A transactions.
Optimal insurance risk allocation with steepest ascent and genetic algorithms
Authors: Ha SiewMun 
Published: June 2013

PurposeEnhanced risk management through the application of mathematical optimization is the next competitive‐advantage frontier for the primary‐insurance industry. The widespread adoption of catastrophe models for risk management provides the opportunity to exploit mathematical optimization techniques to achieve superior financial results over traditional methods of risk allocation. The purpose of this paper is to conduct a numerical experiment to evaluate the relative performances of the steepest‐ascent method and genetic algorithm in the solution of an optimal risk‐allocation problem in primary‐insurance portfolio management.Design/methodology/approachThe performance of two well‐established optimization methods – steepest ascent and genetic algorithm – are evaluated by applying them to solve the problem of minimizing the catastrophe risk of a US book of policies while concurrently maintaining a minimum level of return.FindingsThe steepest‐ascent method was found to be functionally dependent on, but not overly sensitive to, choice of initial starting policy. The genetic algorithm produced a superior solution to the steepest‐ascent method at the cost of increased computation time.Originality/valueThe results provide practical guidelines for algorithm selection and implementation for the reader interested in constructing an optimal insurance portfolio from a set of available policies.
Longevity risk and survivor derivative pricing
Authors: Dawson Paul , Lin Hai , Liu Yangshu 
Published: June 2013

PurposeLongevity risk, that is, the uncertainty of the demographic survival rate, is an important risk for insurance companies and pension funds, which have large, and long‐term, exposures to survivorship. The purpose of this paper is to propose a new model to describe this demographic survival risk.Design/methodology/approachThe model proposed in this paper satisfies all the desired properties of a survival rate and has an explicit distribution for both single years and accumulative years.FindingsThe results show that it is important to consider the expected shift and risk premium of life table uncertainty and the stochastic behaviour of survival rates when pricing the survivor derivatives.Originality/valueThis model can be applied to the rapidly growing market for survivor derivatives.
Selecting the right supply chain based on risks
Authors: Wieland Andreas 
Published: June 2013

PurposeThe purpose of this paper is to propose a model that enables a company to select the supply chain strategy based on risk probability p (measure of how likely/often a detrimental event occurs) and risk impact i (expression of the significance of a loss when that event occurs).Design/methodology/approachThis paper discusses four supply chain strategies: agility, robustness, resilience and rigidity. Mathematical models are used for the strategies' cost functions, which reveal optimal solutions and break‐even points in dependence of p and i.FindingsThis paper proposes that resilience is appropriate in the case of high supply chain risk probability and impact, and rigidity if both values are low. When only risk impact is low, robustness is optimal, whereas agility is optimal when only risk probability is low.Research limitations/implicationsThis research extends existing models for selecting the appropriate supply chain strategy.Practical implicationsKnowledge of the interplay between the strategies' cost functions and risk probability and risk impact is vital for companies. This may encourage managers to become more familiar with their strategy costs and supply chain risks.Originality/valueTo the author's knowledge, no corresponding model exists so far that links risk impact and risk probability to the four supply chain strategies.
A supply chain configuration model for reassessing global manufacturing in China
Authors: Huang George Q. , Zhang Abraham , Liu Xiaming 
Published: June 2013

PurposeGlobal manufacturers have faced unprecedented cost pressures in China because of Chinese currency appreciation, rising labour costs, higher oil prices and reduced value‐added tax rebates. This paper aims to reassess the decision of operating global manufacturing facilities in China.Design/methodology/approachA mixed integer programming model is developed for a typical global manufacturing supply chain that includes production in the Pearl River Delta region and trade in Hong Kong. A case study with a footwear product is used to illustrate model application and present detailed analyses.FindingsThe modelling results affirm the need of relocating labour‐intensive production that mainly competes on low costs. Nevertheless, coastal China offers considerable benefits from industrial clustering and a logistics advantage in comparison with inland China and Asian countries where labour costs are still relatively low. Hong Kong remains a robust location choice for trade operations because of its favourable tax policies.Practical implicationsRetaining production in China faces high risks from Chinese currency appreciation, while relocation to lower‐cost Asian countries is more vulnerable to risks from high oil prices. An intermediate trade operation in Hong Kong can be used to hedge against risks from unfavourable tax policy changes at manufacturing locations.Originality/valueChina has risen to an important position in global manufacturing because of its cost advantages. This paper analyzes the new phenomenon of dramatically increasing cost pressures in China. It develops a first‐of‐its‐kind supply chain configuration model for the popular front‐shop‐back‐factory business model in China.
TPM implementation in large and medium size organisations
Authors: Aspinwall Elaine , Elgharib Maged 
Published: June 2013

PurposeThe purpose of this paper is to ascertain how total productive maintenance (TPM) has been implemented in large and medium size UK manufacturing companies, focusing on why such a programme was introduced, the activities involved, and the effectiveness and difficulties encountered during the process.Design/methodology/approachThe aspects listed were based on a review of the literature. A case study approach was favoured to collect the necessary data. Companies were contacted, four of which responded favourably, and a protocol was developed to enable interviews to be carried out at each.Findings“Culture” was highlighted as the main obstacle to successfully implementing TPM; others were lack of awareness about the advantages of the programme, low employee skills and high cost. Two benefits gained by the four companies were a significant improvement in the availability and performance of the equipment within the plant and improved communication between employees. Additional benefits were financial improvement, reduced energy cost and increased employee morale and job satisfaction.Research limitations/implicationsThe number of companies that were willing to take part in the study was poor, thereby making it difficult to generalise the conclusions.Practical implicationsThe results should help large and medium size organisations to better understand the TPM discipline, to facilitate its adoption and prioritise its practice. They also highlight the effectiveness and obstacles that can be encountered during the process.Originality/valueThe paper highlights the strong potential of TPM implementation programmes in affecting organisational performance improvements. The study also offers a beneficial source of information to organisations, which are still lagging far behind when it comes to TPM practices.
