Trajectory evaluation for manipulators with motion and sensor uncertainties
Authors: Qi Ruolong , Zhou Weijia , Tiejun Wang 
Published: July 2017

Purpose
Uncertainty can arise for a manipulator because its motion can deviate unpredictably from the assumed dynamical model and because sensors might provide information regarding the system state that is imperfect because of noise and imprecise measurement. This paper aims to propose a method to estimate the probable error ranges of the entire trajectory for a manipulator with motion and sensor uncertainties. The aims are to evaluate whether a manipulator can safely avoid all obstacles under uncertain conditions and to determine the probability that the end effector arrives at its goal area.

Design/methodology/approach
An effective, analytical method is presented to evaluate the trajectory error correctly, and a motion plan was executed using Gaussian models by considering sensor and motion uncertainties. The method used an integrated algorithm that combined a Gaussian error model with an extended Kalman filter and a linear–quadratic regulator. Iterative linearization of the nonlinear dynamics was used around every section of the trajectory to derive all of the prior probability distributions before execution.

Findings
Simulation and experimental results indicate that the proposed trajectory planning method based on the motion and sensor uncertainties is indeed highly convenient and efficient.

Originality/value
The proposed approach is applicable to manipulators with motion and sensor uncertainties. It helps determine the error distribution of the predefined trajectory. Based on the evaluation results, the most appropriate trajectory can be selected among many predefined trajectories according to the error ranges and the probability of arriving at the goal area. The method has been successfully applied to a manipulator operating on the Chinese Space Station.
Modular design of a teleoperated robotic control system for laparoscopic minimally invasive surgery based on ROS and RT-Middleware
Authors: Bai Weibang , Cao Qixin , Wang Pengfei , Chen Peng , Leng Chuntao , Pan Tiewen 
Published: July 2017

Purpose
Robotic systems for laparoscopic minimally invasive surgery (MIS) always end up with highly sophisticated mechanisms and control schemes – making it a long and hard development process with a steep price. This paper aims to propose and realize a new, efficient and convenient strategy for building effective control systems for surgical and even other complex robotic systems.

Design/methodology/approach
A novel method that takes advantage of the modularization concept by integrating two middleware technologies (robot operating system and robotic technology middleware) into a common architecture based on the strengths of both was designed and developed.

Findings
Tests of the developed control system showed very low time-delay between the master and slave sides; good movement representation on the slave manipulator; and high positional and operational accuracy. Moreover, the new development strategy trial came with much higher efficiency and lower costs.

Research limitations/implications
This method results in a modularized and distributed control system that is amenable to collaboratively develop; convenient to modify and update; componentized and easy to extend; mutually independent among subsystems; and practicable to be running and communicating across multiple operating systems. However, experiments show that surgical training and updates of the robotic system are still required to achieve better proficiency for completing complex minimally invasive surgical operations with the proposed and developed system.

Originality/value
This research proposed and developed a novel modularization design method and a novel architecture for building a distributed teleoperation control system for laparoscopic MIS.

Published: July 2017

Purpose
The purpose of this paper is to investigate the combined effects of customer aggression, job stress, and emotional intelligence (EI) on job satisfaction and organizational turnover among managers from a developing country, i.e. Pakistan.

Design/methodology/approach
Data are collected from 230 respondents working as bank managers in Pakistan by means of a cross-sectional survey. The collected data are analyzed by employing a structural equation modeling (SEM) technique.

Findings
The employees perceive that job stress positively influences emotional exhaustion among employees. Furthermore, EI negatively influences job exhaustion to minimize the potential to lead it through to organizational turnover.

Originality/value
The combined effects of customer- and organization-related elements have been scarcely investigated – the heart and soul of contribution regarding this research. The moderation of EI to lessen the emotional exhaustion is a significant contribution to this study. Finally, the context of Pakistan’s banking sector is also unique to this study.

Authors: Marathe Gaurav , Balasubramanian Girish , Singhal Manish 
Published: July 2017

PurposeThe purpose of this paper is to argue for theoretical integration as a major step in consolidation of the vast leadership literature. It is an attempt to lay out a basic canvas that could be further used for building an integrated theory of leadership.Design/methodology/approachThe concept matrix framework (Webster and Watson, 2002) has been used for analytical abstraction to organize the published research on leadership and distill certain commonalities. The paper finally proposes certain pivots for theoretical integration of the leadership literature.FindingsA thorough analysis of the leadership literature and the identification of commonalities within the various theories help the authors to identify the change and collective filter, outcomes of leadership, organizational outcomes, leadership role, sources of leadership, processes within the larger leadership process and the context as the pivots for building an integrated theory of leadership.Research limitations/implicationsWhile the paper is not a detailed literature review and lacks predictive power, it is a synthesis of the published literature. The paper proposes a descriptive model meant to provide a sound foundation for an integrated theory of leadership.Practical implicationsThe paper provides a framework to reduce the complexity and ambiguity of leadership research literature and could be utilized as a starting platform for an integrated theory of leadership. It is hoped that this shall also provide leaders and leadership training providers with a more holistic approach for leadership assessment and development.Originality/valueBased on a survey of literature, the explanation of the leadership process, suggestions for evaluation of quality of leadership and pivots for theoretical integration are the main contributions.
Scaling the notion of Islamic spirituality in the workplace
Authors: Adawiyah Wiwiek Rabiatul , Pramuka Bambang Agus 
Published: July 2017

Purpose
Exponential growth in interest of workplace spirituality has led to the development of numerous theories based on various religious faiths. The purpose of this paper is to introduce the underlying dimensions of workplace spirituality in Islam by developing a scale to measure it and to present a subset of knowledge on workplace spirituality from both western and Islamic perspectives.

Design/methodology/approach
The authors collected data from 223 employees working at Islamic-based institutions in Indonesia. They tested the validity and reliability of the proposed indicators of Islamic workplace spirituality using exploratory and confirmatory factor analysis.

Findings
This study enhances the literature in the field of human resources development, especially in the area of workplace spirituality, by empirically assessing the extent of spirituality in the Islamic workplace. The findings revealed 13 indicators that define Islamic workplace spirituality in the Indonesian business organizational context.

Research limitations/implications
This study was limited to Indonesia. In order to apply the 13 indicators in a broader, more global context, researchers need to conduct similar studies on a number of institutions worldwide.

Practical implications
Scholars and professionals may use the research findings to justify their efforts in designing, developing, and implementing appropriate learning and performance improvement interventions, so that Islamic spirituality can increase continuously among employees.

Social implications
This study provides guidelines to the human resources managers of Islamic-based institution to assess the degree of spirituality of each job applicants during job selection.

Originality/value
This study is one of the first attempts to examine and measure Islamic spirituality in the workplace, not only in Indonesia, but also worldwide. The 13 indicators, drawn from religious psychology, provide a new scale to measure spirituality.
Mediating effect of knowledge management on organizational learning culture in the context of organizational performance
Authors: Wahda  
Published: July 2017

Purpose
The purpose of this paper is to determine the mediating effect of knowledge management (KM) on organizational learning culture (OLC) in the context of organizational performance of the State Organization for Higher Education (PTN) in South Sulawesi.

Design/methodology/approach
The unit of analysis in this study includes a study program of exact sciences, non-exact science scholars, as well as the study population. Sample size is 138 units/respondents. Analysis method used to test the research hypothesis is partial least square (PLS) by employing XLSTAT.

Findings
The results of analysis show that the exact science, non-exact science, and exact-non-exact OLC have a significant positive effect on KM. This means that when an OLC is strongly implanted, the KM will be well implemented. Therefore, to carry out the KM well, it is imperative that there should be a suitable organizational culture. In this case, an OLC has the biggest effect on achieving organizational performance.

Originality/value
KM in organizations has been researched by performing case studies on sub-companies of a selected corporation in the city of Esfahan and on OLC in a public service organization of Pakistan. This paper claims originality on the basis of the following: variables used are mediating variables of KM, learning organizational culture, and organizational performance; the method used in this research is PLS and the locations used in this study, sites at the State University of Makassar in Indonesia, are unique as they have not been used in any previous studies on this topic.
Applying the resource-based view to alliance formation in specialized supply chains
Authors: Steiner Bodo , Lan Kevin , Unterschultz Jim , Boxall Peter 
Published: July 2017

PurposeThe purpose of this paper is to explore drivers of alliance formation in a specialized supply chain from a manager’s perspective, focussing on firm-specific resources, resources embedded in inter-firm relationships and capabilities under the control of the focal firm.Design/methodology/approachThis paper focusses on the resource-based view to obtain insights from the analysis of a manager survey conducted in Canada’s beef sector, applying a logistic regression approach to study alliance formation.FindingsIn identifying significant roles for resource richness and diversification of resource usage, the analysis highlights the importance of resource characteristics underlying factor market imperfections as drivers of alliance formation in a single primary input supply chain. The results suggest that resource heterogeneity is important for alliance formation and organizational success in specialized supply chains.Research limitations/implicationsIf previous alliance-related experience of managers, controlled for in the underlying cross-sectional survey, serves as an approximation for persistent unobservables impacting the alliance formation decision, we may face spurious state-dependence.Practical implicationsManagers interested in building compatible alliances in specialized single primary input supply chains may benefit from an improved understanding of the differential role of resource characteristics and resource heterogeneity for alliance formation, as these can function as a source of competitive advantage.Originality/valueThe analysis provides new insights from an individual manager’s perspective on alliance formation drivers in a specialized agri-food supply chain, thereby solidifying extant findings on alliance formation obtained in other sectors. The study contributes to the understanding of the role of resources in alliance formation with regard to prior relationship experience, resource heterogeneity and thus causal ambiguity, thereby also contributing to the debate of the role of relational capabilities vs firm-internal resources for sustained competitive advantage.

Published: July 2017

PurposeThe purpose of this paper is to empirically examine the effects of different R&D funding inputs – including funding for basic research, applied research, and development – on different innovation outcomes (e.g. inventions, patents, licenses, and start-ups).Design/methodology/approachThe study borrowed the resource dependence theory perspective by focusing on the proportion of funding secured from various external sources that fund university R&D, and assessed its effect on the nature and outcomes of the university research activity.FindingsResults indicated that greater funding of basic research was associated with more inventions and patents; greater funding of applied research was associated with more licenses; and greater funding for development activities was associated with more university start-ups.Originality/valueThe contributions of this study are two folded: first, it added to the debate that more R&D investment is indeed associated with more innovation outcomes; and second, it is important to differentiate the R&D funding inputs as they are related to different innovation outcomes.
Learning from errors in dual vocational education: video-enhanced instructional strategies
Authors: Cattaneo Alberto A.P. , Boldrini Elena 
Published: July 2017

Purpose
Starting from the identification of some theoretically driven instructional principles, this paper presents a set of empirical cases based on strategies to learn from errors. The purpose of this paper is to provide first evidence about the feasibility and the effectiveness for learning of video-enhanced error-based strategies in vocational education and training.

Design/methodology/approach
Four different cases are presented. All of them share the same design-based research perspective, in which teachers and researchers co-designed an (iterative) intervention in the field. Two cases are preliminary investigations, while the other two profit from a quasi-experimental design with at least one experimental condition based on error treatment and a control group.

Findings
The four cases show the effectiveness of learning from error (and from error analysis). More specifically, they show the validity and flexible adoption of the specific instructional principles derived from the literature review: the use of inductive strategies and in particular, of worked-out examples; the reference to a concrete, possibly personal, experience for the analysis task; the use of prompted writing to elicit self-explanations and reflection; and the use of video for recording and annotating the situation to be analysed.

Research limitations/implications
The four cases constitute only a starting point for further research into the use of errors for procedural learning. Moreover, the cases presented are focused on learning in the domain of procedural knowledge and not in that of declarative knowledge. Further studies in the vocational education and training sector might serve this research area.

Practical implications
The paper provides concrete indications and directions to implement effective instructional strategies for procedural learning from errors, especially within vocational education.

Social implications
Errors are often identified with and attributed to (individual) failures. In both learning institutions and the workplace, this can engender an intolerant and closed climate towards mistakes, preventing real professional development and personal growth. Interventions on learning from errors in schools and workplaces can play a role in changing such a culture and in creating a tolerant and positive attitude towards them.

Originality/value
The majority of studies about learning from errors are focused on disciplinary learning in academic contexts. The present set of cases contributed to filling in the gap related to initial vocational education, because they deal with learning from errors in dual vocational training in the field of procedural knowledge development. Moreover, a specific contribution of the presented cases relies on the use of video annotation as a support that specifically enhances error analysis within working procedures.

Authors: Paul GD Bino , Achar Anantha Padhmanabha , Muniyoor Krishna , R. Venkatesh Murthy 
Published: July 2017

Purpose
This paper aims to investigate the factors that determine the performance of small business units using a field survey conducted in a small jewellery cluster in Mangalore district of Karnataka state (India).

Design/methodology/approach
The estimates of the median-based quantile regression model are used to analyse how a change in small firm output is determined by seven key factors such as year of establishment, the source of finance, the source of design, lack of demand, design done by the staff, the number of skilled workers, and constraints.

Findings
The study finds that the factors such as sources of finance, design, customer relation and skilled manpower are the major determinants of the growth of jewellery business. Based on the findings, the study suggests that the invigoration of business performance by high degree of competitiveness, coupled with technological advancement and hiring of skilled labour, is essential for the sustainability of jewellery units.

Originality/value
The study pinpoints the problems and prospects of traditional business units located in an industrial cluster. Further, it suggests the different ways of strengthening the performance of small business units in India.
Dealing with organizational silos with communities of practice and human resource management
Authors: Forsten-Astikainen Riitta , Hurmelinna-Laukkanen Pia , Lämsä Tuija , Heilmann Pia , Hyrkäs Elina 
Published: July 2017

PurposeOrganizational silos that build on the existing organizational structures are often considered to have negative effects in the form of focus on private narrow objectives and organizational fragmentation. To avoid such harmful outcomes, competence management is called for, and in this, the human resources (HR) function takes a key role. Among other things, it can provide basis for emergence and utilization of communities of practice (CoPs) that build on common interests and effectively cross organizational boundaries. These features of CoPs allow them to carry competences and ease knowledge transfer and to break down the harmful isolation. Quite paradoxically, the challenge is that CoPs can also form within silos, thereby strengthening isolation, and HR as a utility department can itself be particularly prone to the silo effects. Examination of boundaries and silos through an original study conducted in a Finnish energy sector company suggests that HR managers need competences outside their own expertise area and courage to augment their CoPs across the functional boundaries to break out of the HR silo and to assist other functions to do the same.Design/methodology/approachThe study is based on qualitative research data gathered in four focus group interviews with HR personnel from an energy sector company in November 2012. Totally, 19 professionals were interviewed (five HR partners, five talent development and performance managers, five vice presidents of HR and four HR managers) in the four focus groups. The company’s HR personnel represented units from Finland, Sweden, Poland and Estonia.FindingsExamination of boundaries and silos in the Finnish energy sector suggests that HR managers need competences outside their own field (e.g. knowledge of the business and offerings of the firm) and courage to augment their CoPs across the functional boundaries to break out of the HR silo and to assist other functions to do the same.Originality/valueResearch provided that CoPs can have different effects on silos. As they are capable of crossing organizational and functional boundaries, they may effectively mitigate adverse silo effects; however, if CoPs are formed within silos, they may strengthen isolation and fragmentation. In addition, utility departments and supporting functions are particularly prone to the risk of CoPs forming within silos. The HR function is one manifestation of this. Paradoxically, it also has the potential to enhance the other type of effects that CoPs can exert, as competence management can be used to foster intentional and self-organizing CoPs that counter silo effects.
Learning strategies at work and professional development
Authors: Haemer Hannah Deborah , Borges-Andrade Jairo Eduardo , Cassiano Simone Kelli 
Published: July 2017

Purpose
This paper aims to investigate the prediction of current and evolutionary perceptions of professional development through five learning strategies at work and through training and how individual and job characteristics predict those strategies.

Design/methodology/approach
Variables were measured in a cross-sectional survey, with 962 individuals. Relationships were tested through linear regression analysis and structural equation modeling.

Findings
The criterion variable current professional development is positively associated to three learning strategies: intrinsic and extrinsic reflection, seeking help from others and trial and error. The relationship between this latter learning strategy and that criterion variable is moderated by work experience. Hours of training also predict that criterion variable. Seeking help from others and educational level predict perceived evolutionary development. Socio-cultural and technical-organizational work environment variables predict those five strategies.

Research limitations/implications
The cross-sectional research design yields potential for monomethod bias. Longitudinal, multilevel and multiple collection design studies should be conducted in the future.

Originality/value
A wide range of occupations and organizational contexts was investigated by using two different measures of professional development as criterion variables. A larger effect size was found for one of them, given just three learning strategies as antecedent variables. Training and formal education had smaller effects. The importance of taking into account different characteristics of workplace learning environments is highlighted.
