Characterization and experimental evaluation of gear transmission errors in an industrial robot
Authors: Slamani Mohamed , Bonev Ilian A. 
Published: August 2013

PurposeThis paper proposes a simple technique for assessing the effect of gear transmission errors in a six‐axis industrial serial robot, as these errors can vitally affect the industrial robot's positioning accuracy.Design/methodology/approachThe experimental procedure is developed using a laser interferometer system to measure bidirectional linear position errors for an ABB IRB 1600 industrial robot. A simple technique based on fast Fourier transformation (FFT) analysis is devised and implemented for the characterization, evaluation, and quantification of gear transmission errors. Structural deformation and backlash error are also discussed.FindingsThe authors found that the major sources of error affecting the performance of the robot come from joints two and three. They also found that eccentricity errors, structural deformations, and backlash are the most important sources of error affecting the accuracy and the repeatability of the industrial robot studied. Additional tests show that the robot's first joint has relatively poor bidirectional repeatability.Practical implicationsThe usefulness of a laser tracker (or any other large range portable 3D measurement system) is questionable for assessing – let alone analyzing in depth – the gear transmission errors of some of today's industrial robots. The authors demonstrate in this paper that a laser interferometer system can successfully measure gear transmission errors very accurately. The proposed methodology is simple, efficient, and easy to use for the characterization and quantification of the errors.Originality/valueThis work is the first to detail the use of the laser interferometer system for the characterization of the gear transmission errors of an industrial robot. A methodology has been developed and implemented for very accurately quantifying the effects of gear transmission errors, structural deformations, and backlash. The proposed methodology greatly simplifies the measurement set‐up and accelerates error quantification.
Fuzzy neural control for unmanned robot applied to automotive test
Authors: Chen Gang , Zhang Wei‐gong , Zhang Xiao‐na 
Published: August 2013

PurposeThe paper aims to overcome the shortcomings that proportional‐integral‐derivative (PID) control for unmanned robot applied to automotive test (URAT) needs a priori manual retuning, has large speed fluctuations and is hard to adjust control parameters. A novel control approach based on fuzzy neural network applied to URAT was proposed.Design/methodology/approachAccording to the target vehicle speed and driving command table, the multiple manipulator coordinated control model was established. After that, the displacement of throttle mechanical leg, clutch mechanical leg, brake mechanical leg and shift mechanical arm for URAT was used as input of fuzzy neural network (FNN) model, and vehicle speed was used as output of FNN model. The number of membership functions was three, and the type of that was generalized bell membership function (gbellmf). The hybrid learning algorithm which combined with back propagation algorithm and least square method was applied to train the model. The Sugeno model was selected as fuzzy reasoning model.FindingsExperimental results demonstrated that compared with PID control method, the proposed approach can greatly improve the accuracy of vehicle speed tracking. The approach can accurately realize the vehicle speed tracking of given driving test cycle. Therefore, it can ensure the accuracy and effectiveness of automotive test results.Research limitations/implicationsFuture work will focus on improving the efficiency of this learning algorithm.Practical implicationsThe paper provides effective methods for improving the accuracy of speed tracking and repeatability.Originality/valueAfter establishing the multiple manipulator coordinated control model, this paper proposes a novel control approach based on FNN for URAT.
Online measurement based tool path generation toward integrated robotic laser cladding
Authors: Liu Jie 
Published: August 2013

PurposeRefurbishing may be the most practical approach under the low volume production. This effort aims to achieve robotic laser cladding with the main purpose of achieving maximum processing flexibility, predictably high quality, lower maintenance and operating costs. This study aims to focus on online measurement and cladding path generation toward automatic laser cladding.Design/methodology/approachBased on the specific requirements of automatic laser cladding, an approach was proposed toward an automatic laser cladding with powder injection for the refurbishment of components with free‐form surfaces. This study assessed the feasibility of integrating a non‐contact free‐form surface measurement system, an industrial robot, and an algorithm for generating cladding tool paths seamlessly.Findings3D laser scanning and laser cladding systems can be embedded into an existing robot motion control system. Online measurement based 3D surface reconstruction is a practical approach toward cladding tool path generation for on‐site refurbishment.Practical implicationsRobotic laser cladding may be a potential application by integrating other measurement devices, such as temperature sensor based monitoring system.Originality/valueRefurbishing worn‐out components could have significant economic benefits. This study indicates that robotic laser cladding may potentially facilitate improved refurbishment of oversized components.
Why I act differently: studying patterns of legitimation among CIOs through motive talk
Authors: Magnusson Johan , Bygstad Bendik 
Published: August 2013

PurposeIT governance has become the recognized norm system for chief information officers. The purpose of this paper is to understand how CIOs relate to these norms, by studying how they legitimate incompliance with the norms.Design/methodology/approachThe paper uses an interpretive, qualitative, structured interview study with 18 CIOs in large Swedish organizations regarded as having excellent IT governance practice, using motive talk as analytical lens to identify the informants’ relationship to norms.FindingsThe study identifies norm‐specific patterns for how CIOs legitimate incompliance with IT governance, finding that CIOs use a combination of excuse and justifications as strategies of legitimation. The study also finds that CIOs display a tendency of not contesting IT governance‐related norms unless these are in conflict with neighboring professional jurisdictions. This is regarded as an identification of the “margins” of IT governance.Research limitations/implicationsThe study illustrates how the theory of motive talk is a viable road ahead for future studies of IT professionals. The generalizability of the identified patterns of legitimation is limited by the selection of large organizations with solely male CIOs, as well as the selection of solely organizations that have succeeded in establishing external legitimacy concerning IT governance and the organizations being Swedish.Practical implicationsCIOs aspiring to increase their legitimacy should avoid direct conflicts with neighboring professions. In addition to this, they should also aspire to be clear in a separation of motive talk and actual practice, since full norm compliance may be detrimental to their factual operations.Originality/valueThe originality of this paper lies in the methodological approach of combining motive talk and speech acts to investigate CIO legitimation practices.
Acquirer's earnings quality and the choice of payment method in mergers and acquisitions
Authors: Yung Kenneth , Sun Qian , Rahman Hamid 
Published: August 2013

PurposeThe purpose of this paper is to investigate the role of acquirer's earnings quality on the choice of payment method in mergers and acquisitions (M&A).Design/methodology/approachThe paper applies a simultaneous equations model to address the concern of endogeneity between earnings quality and payment method in corporate acquisitions. In addition, a propensity score matching model is used for robustness purpose.FindingsPrevious studies imply that short‐term accruals have a significant impact on the choice of payment method in M&A. In this study, This paper shows that acquisition financing is not significantly affected by short‐term earnings quality once control variables are considered. Instead, this paper finds that it is the long‐term earnings quality of the acquirer that matters. Acquiring firms with poor (good) long‐term earnings quality prefer lower (higher) cash payment in acquisitions. Their results are robust to different definitions of earnings quality.Research limitations/implicationsResearchers should consider the effect of long‐term earnings quality in their future investigations.Practical implicationsInvestors should be aware of this issue when evaluating corporate mergers.Originality/valueThis is the first study to examine the impact of long‐term quality of earnings on the choice of payment method in M&A.
Does information production explain bidder liquidity after takeovers?
Authors: Lei Adam Y.C. , Li Huihua 
Published: August 2013

PurposeThe purpose of this paper is to determine whether information produced in the takeover process or changes in firm characteristics after takeovers affect bidder liquidity.Design/methodology/approachThis paper compares the liquidity changes for bidders that complete their takeovers (successful bidders) and bidders that eventually withdraw their takeover attempts (unsuccessful bidders) to disentangle the information production hypothesis and the firm characteristics hypothesis. The authors use both media mentions and changes in the standard deviation of market model residuals to proxy for the information produced in the takeover process, intraday data to construct the liquidity measures, and regression analyses to examine the determinants of bidder liquidity changes.FindingsThis paper finds that unsuccessful bidders experience no less information production than successful bidders during the takeover process, but only successful bidders enjoy liquidity improvements. Once the authors control for the changes in firm characteristics, whether a takeover is successful or not no longer affects bidder liquidity. Moreover, information production reduces information asymmetry for successful Nasdaq bidders but not NYSE bidders. These findings collectively support the firm characteristics hypothesis but also suggest a role of information production on firms with higher information asymmetry.Originality/valueThis paper provides the direct evidence that the information produced in the takeover process does not lead to liquidity improvements of the bidders. It also supplements existing literature with a more comprehensive sample and sheds light on how acquisition withdrawals affect firms' liquidity.
Community participation and social inclusion in Bristol
Authors: Fieldhouse Jon , Donskoy Anne‐Laure 
Published: August 2013

PurposeThis paper reports on action research which explored assertive outreach service users’ experiences of community participation and then fed this learning into a multi‐agency forum – where it was used in joint‐planning between mental health services and community partners, aiming to maximise social inclusion locally.Design/methodology/approachAction research methodology was chosen to examine the forum's work because it brings together different perspectives to reveal an issue in its entirety and effect change in practice. Service users’ experiences were explored using semi‐structured qualitative interviews.FindingsEngagement in mainstream community‐based activities re‐connected service users with cherished life roles and developed feelings of self‐efficacy, belonging, and wellbeing. Effective inter‐sectoral working in the forum was based on a shared agenda and collective action planning.Research limitations/implicationsWhilst every effort was made to ensure an authentic service user voice informed service development, it is unfortunate – in action research terms – that no service user interviewees were able to participate directly in the work of the forum. Community development work can build on micro‐level, person‐centred mental health care and extend outwards to collective community activity, aiming to harness social capital.Practical implicationsAssertive outreach – harnessing mainstream occupations through care‐planning – achieved outcomes that institutional rehab could not, and did so with a minimum of stigmatisation.Social implicationsThis inquiry highlights that social inclusion is the responsibility of the community as a whole.Originality/valueThis inquiry appreciated service users as evaluators of the services they used and aimed to bring that knowledge to bear on service development.
Improving social inclusion for young people diagnosed with “first episode psychosis”: employment, education and online support
Authors: Holttum Sue 
Published: August 2013

PurposeThis article aims to summarise two papers from Australia on supporting young people in early intervention for psychosis. Both have implications for young people's social inclusion and the design of early intervention services.Design/methodology/approachThe first paper reports a new analysis of a trial of specialist employment and education support in an early intervention service. It used a statistical method called logistic regression to test whether only employment support predicted 41 participants’ success in getting into employment and education, or whether things like condition severity also mattered. The second paper reports on a new online support package for young people with “first episode psychosis” and how acceptable it was. The authors looked at 20 participants’ use of the package, and examined their well‐being before and after using it.FindingsThe first paper reported that nothing except getting specialist employment and education support predicted young people's entry to work or education. They recommend that young people in early intervention should not be denied vocational support because of things like “psychiatric symptoms”. In the second paper, young people in early intervention who used the online package reacted positively. The authors recommend a full controlled trial of the package. It could help young people when leaving the service to maintain their gains.Originality/valueThese papers advance research on early intervention psychosis services regarding young people's social inclusion needs. Specialist vocational support could prevent life‐long social exclusion. An innovative online support package has not yet been proven, but with fast‐evolving technology, it might help future service users stay well when leaving the service.

PurposeThis paper aims to be a conversation with Frank Hoy, conducted by Santiago Ibarreche, about his career as an internationally known scholar in the field of entrepreneurship and family business.Design/methodology/approachThis paper is an interview.FindingsThe interview explores Hoy's career, his achievements and continued search for excellence in terms of research, intertwined with his entrepreneurial ventures.Originality/valueThe interview in this special section, A Life in Research, brings out an individual scholar's experience and history, not only as recognition of scholarly impact, but also as recognition of the person.
Network analysis of user generated content quality in Wikipedia
Authors: Ingawale Myshkin , Dutta Amitava , Roy Rahul , Seetharaman Priya 
Published: August 2013

PurposeSocial media platforms allow near‐unfettered creation and exchange of user generated content (UGC). Drawing from network science, the purpose of this paper is to examine whether high and low quality UGC differ in their connectivity structures in Wikipedia (which consists of interconnected user generated articles).Design/methodology/approachUsing Featured Articles as a proxy for high quality, a network analysis was undertaken of the revision history of six different language Wikipedias, to offer a network‐centric explanation for the emergence of quality in UGC.FindingsThe network structure of interactions between articles and contributors plays an important role in the emergence of quality. Specifically the analysis reveals that high‐quality articles cluster in hubs that span structural holes.Research limitations/implicationsThe analysis does not capture the strength of interactions between articles and contributors. The implication of this limitation is that quality is viewed as a binary variable. Extensions to this research will relate strength of interactions to different levels of quality in UGC.Practical implicationsThe findings help harness the “wisdom of the crowds” effectively. Organisations should nurture users and articles at the structural hubs from an early stage. This can be done through appropriate design of collaborative knowledge systems and development of organisational policies to empower hubs.Originality/valueThe network centric perspective on quality in UGC and the use of a dynamic modelling tool are novel. The paper is of value to researchers in the area of social computing and to practitioners implementing and maintaining such platforms in organisations.
Sensitivity in topic development and meaning making in a process consultation contract meeting
Authors: Puutio Risto , Kykyri Virpi‐Liisa , Wahlström Jarl 
Published: August 2013

PurposeThe purpose of this paper is to explore the discursive practices used when the agenda for a consultation process was negotiated in a contract meeting. The paper illustrates the role of sensitivity in meaning making practices, that is, how displays of sensitivity were intertwined with topic development.Design/methodology/approachThe paper offers an in‐depth analysis of naturally occurring conversation in a meeting between a consultant and two client managers. The audio‐recorded data is analyzed by utilizing methodology introduced and developed in the traditions of Ethnomethodology and Conversation Analysis (CA).FindingsThe authors show how both the consultant and the clients displayed markers of sensitivity when introducing various meaning potentials relevant to the topics under discussion, and how they eventually ‘negotiated’ meanings through formulations and reformulations of the topics.Practical implicationsThe findings suggest that indirect and complex discursive practices were functional in that they afforded the participants the possibility to exhibit prospectively threatening meaning potentials of the issues under discussion, while suspending a more thorough topic penetration. The study sheds light on the importance of the details at the early stages of a consulting relationship and the consultant's specific role at the beginning.Originality/valueThe paper illustrates real life practices in process consultation. This sort of data is seldom used in research.
Silent stories of resistance to doing employment
Authors: Mulhall Sue 
Published: August 2013

PurposeExploring experiences of participants on an Irish active labour market programme, the purpose of this paper is to examine accounts of everyday forms of resistance to the subject positions offered in the dominant discourse of “doing employment” espoused on such schemes.Design/methodology/approachEmploying narrative research, the process of individual opposition to established work routines is illustrated at the level of meaning, identity and self‐reflection by using the three‐dimensional narrative inquiry space to chronicle three participants’ stories. Their newly formed subjectivities (created by changes encountered in their past lives and the situations they are experiencing in their present realities) challenge the power of the dominant discourse of ‘doing employment’ on these schemes. The paper illustrates how the individuals respond when confronted with feelings of difference between the subject positions offered within the dominant discourse and their own preferred interest.FindingsTheir stories suggest different forms of micro‐political resistance, from subtle acts and behaviours through to contesting subjectivities and meanings. The article describes how they exercise power in imposing their own meanings through challenge and reinscription, thus rendering the dominant discourse less robust. This creates space for further challenge and reinscription, possibly enabling others to think differently, such as the author, who has moved from unquestioning acceptance of the dominant discourse to an emerging micro‐political resistance to “doing employment”.Originality/valueThese accounts highlight the relevance of using narrative research to reveal, heretofore, silent stories of how individual work routines disrupt prevailing institutional discourse, depicting situations where a story by challenges a story of.

ObjectiveTo compare birth outcomes and maternity care use in 1991 and 2008 by age among primiparous Finnish women.DesignRegister‐based study.SettingNationwide Medical Birth Register.PopulationAll primiparous women in 1991 (n = 24 765) and 2008 (n = 23 511).MethodsWomen aged 35–39 and ≥40 years were compared with women aged 20–34 years in 1991 and 2008, using logistic regression to adjust for women's background.Main outcome measuresMaternity care: prenatal visits, hospitalisation during pregnancy, labour induction, delivery mode, long postpartum hospital stay; and birth outcomes: birthweight, preterm birth, Apgar scores, intensive/observation unit, respiratory care, perinatal death.ResultsIn both years, older women's deliveries were more often induced, instrumental, or by caesarean section. In 2008 compared with 1991, hospitalisations were lower and instrumental deliveries and labour induction were higher in older women. A significant decrease in adjusted odds ratios (OR, 95% confidence intervals) between 1991 and 2008 among women aged 35–39 was found for preterm birth (1.47, 1.18–1.84 versus 0.96, 0.86–1.07) and for intensive/observation unit (1.73, 1.47–2.05 versus 1.21, 1.07–1.37) and, among women aged ≥40 years, for intensive/observation unit (3.14, 2.30–4.29 versus 1.64, 1.31–2.07). The risk for perinatal death (1.66, 0.60–4.60 versus 2.69, 1.07–6.79) was higher in 2008 than in 1991 among women aged ≥40.ConclusionsIn 2008, older primiparous women still used more maternity care, had more interventions, and poorer birth outcomes than younger women, regardless of care advances. Additional risks declined among women aged 35–39 but not among aged ≥40.
