The mediational effect of regulatory focus on the relationships between mindfulness and job satisfaction and turnover intentions
Authors: C. Andrews Martha , Michele Kacmar K. , Kacmar Charles 
Published: November 2014

Purpose
– The purpose of this paper is to explore the role of mindfulness as a predictor of the two components of regulatory focus theory (RFT): promotion and prevention focus. It further examines promotion focus and prevention focus as mediators of the mindfulness-job satisfaction and mindfulness-turnover intentions relationships. Finally, job satisfaction is also examined as a mediator of the mindfulness-turnover intentions relationship.

Design/methodology/approach
– The model was tested using data collected via a snowball approach. Online surveys were distributed to undergraduate students enrolled in a business course. Students were then given the opportunity to earn extra credit by sending the survey to potential respondents. The relationships were tested using structural equation modeling.

Findings
– Support was found for four of the six hypotheses. Prevention focus did not negatively mediate the relationship between mindfulness and job satisfaction as well as the relationship between mindfulness and turnover intentions.

Research limitations/implications
– One limitations of this research is the placement of mindfulness as an antecedent to promotion and prevention focus. Another plausible alternative is to consider mindfulness as a consequence. An additional limitation is the use of a snowball sampling technique. Future research should examine these findings using employees of a single organization.

Originality/value
– This research theoretically and empirically links RFT and mindfulness. This study also adds to the limited research empirically linking RFT and turnover intentions, both directly and indirectly via job satisfaction. Finally, this research extends previous research that established the positive relationship between mindfulness and job satisfaction by examining the mindfulness-job satisfaction-turnover intentions relationship.
Air gap MMF based prediction of eddy current loss in the PMs of concentrated winding brushless machines
Authors: Masmoudi Asma , Masmoudi Ahmed 
Published: November 2014

Purpose
– The purpose of this paper is to an analytical approach-based prediction of the eddy current loss in the PMs of a concentrated winding machine equipped with 12 slots in the stator and ten poles in the rotor.

Design/methodology/approach
– The investigation of the PM eddy current loss has been carried out using an analytical model and a 2D time-stepped transient finite element analysis (FEA).

Findings
– It has been found, in the case of the treated machine, that just the subharmonic of rank 1 and the harmonic of rank 7 have significant contributions to the eddy current loss in the PMs.

Research limitations/implications
– A shift between the results yielded by the developed analytical model and those computed by FEA has been noticed. This limitation is mainly due to the slotting effect which has been omitted in the analytical model.

Practical implications
– Fractional slot PM machines are currently given an increasing attention in automotive applications. The prediction of their iron loss in an attempt to rethink their design represents a crucial efficiency benefit.

Originality/value
– The analytical prediction of the eddy current loss in each PM then in all PMs and their validation by FEA represent the major contribution of this work.

Authors: Miceli Rosario , Gritli Yasser , Di Tommaso Antonino , Filippetti Fiorenzo , Rossi Claudio 
Published: November 2014

Purpose
– The purpose of this paper is to present a diagnosis technique, for rotor broken bar in double cage induction motor, based on advanced use of wavelet transform analysis. The proposed technique is experimentally validated.

Design/methodology/approach
– The proposed approach is based on a combined use of frequency sliding and wavelet transform analysis, to isolate the contribution of the rotor fault components issued from vibration signals in a single frequency band.

Findings
– The proposed technique is reliable for tracking the rotor fault components over time-frequency domain. The quantitative analysis results based on this technique are the proof of its robustness.

Research limitations/implications
– The validity of the proposed diagnosis approach is not limited to the analysis under steady-state operating conditions, but also for time-varying conditions where rotor fault components are spread in a wide frequency range.

Practical implications
– The developed approach is best suited for automotive or high power traction systems, in which safe-operating and availability are mandatory.

Originality/value
– The paper presents a diagnosis technique for rotor broken bar in double cage induction motor base on advanced use of wavelet transform which allows the extraction of the most relevant rotor fault component issued from axial vibration signal and clamping it in a single frequency bandwidth, avoiding confusions with other components and false interpretations.
Dual current control strategy to fulfill LVRT requirements in WECS
Authors: Díaz Matías , Cárdenas-Dobson Roberto 
Published: November 2014

Purpose
– The purpose of this paper is to investigate a control strategy to fulfill low-voltage ride through (LVRT) requirements in wind energy conversion system (WECS).

Design/methodology/approach
– This paper considers an active front-end converter of a grid connected WECS working under grid fault conditions. Two strategies based on symmetrical components are studied and proposed: the first one considers control only for positive sequence control (PSC); the second one considered a dual controller for positive and negative sequence controller (PNSC). The performance of each strategy is studied on LVRT requirements fulfillment.

Findings
– This paper shows presents a control strategy based on symmetrical component to keep the operation of grid-connected WECS under unsymmetrical grid fault conditions.

Research limitations/implications
– This work is being applied to a 2 kVA laboratory prototype. The lab prototype emulates a grid connected WECS.

Originality/value
– This paper validate the PNSC strategy to LVRT requirements fulfillment by experimental results obtained for a 2 kVA laboratory prototype. PNSC strategy allows constant active power delivery through grid-voltage dips. In addition, the proposed strategy is able to grid-voltage support by injection of reactive power. Additional features are incorporated to PNSC: sequence separation method using delay signal cancellation and grid frequency identification using phase locked loop.
Influence of rotor design on performance of PM machines for heavy-duty traction applications
Authors: Jacob Jubin , J.H. Paulides Johannes , Lomonova Elena 
Published: November 2014

Purpose
– The purpose of this paper is to study the performance and efficiency of two different permanent magnet (PM) machine rotor configurations under magnetic core saturation conditions.

Design/methodology/approach
– Since the accuracy of conventional analytical methods is limited under saturation conditions, a finite element model of the machine is built; which is used to predict the various losses over its operating range such as eddy current, hysteresis, copper and magnet losses. Using this model, the efficiency map of the machine is derived which is used to investigate its efficiency corresponding to a heavy vehicle drive cycle. The performance of two different rotor designs are studied and the efficiency of each design is compared under the considered drive cycle.

Findings
– It has also been proved that the performance advantage due to reluctance torque in the v-shaped interior PM (IPM) machine is offset by its core steel saturation at higher current/torque levels. The magnitude of iron losses in the IPM is higher than that in the surface PM (SPM) machine, however, the magnet loss in the SPM is higher than in the IPM.

Originality/value
– An investigation of the performance of the IPM design in comparison with the SPM∼design under magnetic saturation conditions is not known to the authors. Hence, in this paper, it will be determined if the assumed performance advantage of the IPM over the SPM still holds true under these conditions.
An approach to the sizing of electric motors devoted to aerospace propulsion systems
Authors: Bouzidi Ikhlas , Bianchi Nicola , Masmoudi Ahmed 
Published: November 2014

Purpose
– The purpose of this paper is to deal with the design and optimization of permanent magnet synchronous motors (PMSM) devoted to aeronautic applications.

Design/methodology/approach
– A design approach as well as a performance investigation, based on two-dimensional finite element analysis of selected electromagnetic and thermal features, are applied to chosen PM synchronous machine topologies which differ by their number of phases.

Findings
– It has been found that the initial set of geometrical parameters does not fulfill the torque/weight compromise required by a aeronautic applications since it leads to an average temperature rise higher than the authorized limit (class H: 155 K). Therefore, the sizing has been rethought in an attempt to meet the constraints of the considered application.

Research limitations/implications
– Several continuations of the developed works shall be treated in the future, such as: (i) the prototyping of the designed machines, (ii) extending the optimization procedure to the whole drive including the motor and the associated static converter, and (iii) the synthesis and implementation of a dedicated control strategy with a suitable emulation of the load.

Practical implications
– The studied machines could be integrated in aerospace propulsion systems.

Originality/value
– The paper develops a design procedure of PMSM dedicated to aerospace applications where the compromise between torque/weight/temperature represents a crucial design challenge.
Using a case study approach to identify critical success factors for alliance contracting
Authors: Jefferies Marcus , John Brewer Graham , Gajendran Thayaparan 
Published: November 2014

Purpose– There has been a significant increase in the use of relationship contracting in the global construction industry, with strategies such as Partnering, Alliancing and Public-Private Partnerships all used. These approaches were introduced to the Australian construction industry in the 1990s in an attempt to overcome the adversarial nature of traditional contracting methods. The purpose of this paper is to investigate factors that influence the successful implementation of Project Alliancing by means of a case study approach focusing on the procurement of a large water treatment plant. The research findings identify critical success factors (CSFs) both from literature and the case study project.Design/methodology/approach– The research traces the origins of Alliancing and identifies CSFs by reviewing literature and analysing a current case study project. The paper first identifies CSFs on a global scale by establishing a theoretical framework of CSFs and then compares this to the case study project. A case study of an Australian Alliance project is investigated whereby a semi-structured interview process, involving senior managers from the six partners from the Alliance, was used in conjunction with a review of project documentation. The findings of the case study project are compared to the literature and any new CSFs are identified.Findings– Alliancing helps to establish and manage the relationships between all parties, remove barriers and encourage maximum contribution to achieve success. Alliancing provides a project delivery method that promotes open communication, equality and a systematic problem resolution process. Team culture focusing on an “open book/no blame” approach is vital to the success of an Alliance. Five CSFs were identified as specifically influencing the success of the case study project: the use of an integrated Alliance office; the staging of project and stretch targets; establishing project specific key performance indicators; facilitating on-going workshops; and the integration of a web-based management programme.Originality/value– The research findings assist both public and private sectors by identifying factors that are critical for success in Alliancing. Five additional factors were identified as specifically influencing the success of the case study project. Since this research was conducted, Australia has seen a further increase in relationship contracting where the likes of Alliancing is often used as the default approach for certain Public Sector projects. Ongoing research into Alliancing is vital to ensure the development of sustainable procurement models, successful operational viability, fair risk distribution and value for money.

Poverty alleviation via tourism cooperatives in China: the story of Yuhu
Authors: Yang Xiaotao , Hung Kam 
Published: November 2014

Purpose– This study aims to understand whether poverty alleviation can be realized in tourism via tourism cooperatives. As a fast growing industry in the world, tourism has accelerated economic development in many participating places. A large number of tourism cooperatives have emerged to capture conspicuous economic benefits from tourism in many rural areas of China. The role of tourism cooperatives has not yet been explored from the poverty alleviation perspective.Design/methodology/approach– Two field trips to Yuhu Village, Lijiang, China, which included in-depth interviews, were conducted during August and December 2011, aiming at understanding the roles of tourism cooperatives in poverty alleviation. In-depth interviews with villagers (45) and mangers of tourism cooperative (5) were conducted. A systematic coding procedure including open, axial and selective coding was conducted with the software assistance of ATLAS.TI6.2.Findings– Evidence from Yuhu suggested that resources and power changes, both of which are further divided into both individual and collective levels, are the main contributors to substantial improvements of the poor. Material and social resources were significantly accumulated. In addition, empowerment, referring to the improvements in status, legitimacy and capability/knowledge, facilitated villagers to obtain favorable policies. By embracing a more broad understanding of poverty, the tourism cooperative is proven to effectively alleviate the poverty suffering of Yuhu villagers.Originality/value– Understanding poverty from a multi-dimensional perspective is deemed to be critical to reveal the actual story, as evidenced in this study, with analyzing resource flows and power changes at different stages of tourism development. By embracing a more broad understanding of poverty, the role of tourism cooperatives in poverty alleviation was able to be noticed and emerged from in-depth interviews. A systematic scrutiny has been carried out to examine the pro-poor effects brought about by tourism cooperatives.

Authors: Hyuc Ko Min , Chul Kim Kyoung , Suprem Abhijit , Prem Mahalik N. , Sahng Ryuh Boem 
Published: November 2014

Purpose
– The purpose of this paper is to demonstrate System-of-Systems (SoS) approach to design and development of unmanned robotic platform for greenhouse agricultural application.

Design/methodology/approach
– SoS design approach is important in developing engineering products. It was observed that while system integration considers designs in a multi-disciplinary level framework, SoS is viewed as a solution focussed approach. In this paper, the authors have demonstrated SoS approach to develop a mobile robot platform. The wheels of the platform are independently controlled by using brushless DC and stepper motors based on fieldbus type Distributed Control System scheme.

Findings
– The constraints for autonomous traveling were identified during the first phase followed by development of 12 distinct sub-routines during second phase of training. Optimal camera installation angle, driving speeds, steering angle per pixel were found to be valuable constraints for feed-forward parameters for real-time driving. The platform was field tested in a tomato planted greenhouse for yield and weed mapping.

Research limitations/implications
– The paper focusses on studying vision-based autonomous four-wheel-drive (4WD) constraints and their implementation limitations.

Practical implications
– The platform was field tested in a tomato planted greenhouse for yield and weed mapping.

Social implications
– The platform can be used for agricultural operations such as crop scouting, monitoring, spraying, and mapping in a medium to large-scale greenhouse setting.

Originality/value
– The research and presentation is original. Starting from its mechanical specification to wheel performance study, development of path patterns for training and global navigation algorithm for testing and validation were achieved. The platform can autonomously be driven without any manual intervention.
Relaxation of employment protection and labour reallocation
Authors: Malk Liina 
Published: November 2014

Purpose
– Employment law reform enforced in Estonia in mid-2009 provides a good opportunity to examine the outcomes of employment protection legislation (EPL). The purpose of this paper is to evaluate the effects of the reduction in EPL on labour reallocation.

Design/methodology/approach
– The author exploits the micro-data of the Labour Force Survey to estimate the probabilities of one-year worker flows with probit models, and uses a difference in differences (DID) approach to identify the effects of the EPL reform.

Findings
– The author finds that the reduction in EPL seems to have increased the probability of transitions out of employment. At the same time, she does not find any significant effect of this reform on the probability of flows into employment. The evaluation also gives evidence of a lowered probability of job-to-job transitions resulting from the reduction in EPL.

Research limitations/implications
– In this paper, the DID estimation is conducted by using Lithuanians as the control group for Estonians. However, it should be noted that this approach assumes strong similarities between these countries in order to obtain reliable estimates.

Originality/value
– The findings of this paper raise the possibility that the reduction in EPL alone may not have been sufficient for achieving a better reallocation of labour and this is important to consider in the context of further developments in other labour market institutions.
Evaluating the prevalence and nature ofblatin post-Soviet societies
Authors: C. Williams Colin , Onoshchenko Olga 
Published: November 2014

Purpose– The purpose of this paper is to evaluate the extent to which the practice of using personal networks to obtain goods and services or to circumvent formal procedures, known asblatin the Soviet era, persists in post-Soviet societies and whether its character has altered.Design/methodology/approach– To do this, the prevalence and nature ofblatin the education sector in the city of Mykolayiv in Ukraine is analysed using 200 face-to-face structured interviews with a spatially stratified sample of Mykolayiv residents and 30 follow-up semi-structured in-depth interviews.Findings– The finding is thatblatis widely used to gain places in kindergarten, schools and universities. However, unlike Soviet erablatwhich took the form of non-monetised friendly help in the market-oriented society of post-Soviet Ukraine, both possessing control over access to assets such as education, as well as possessing personal connections to those with control over access to these assets, is increasingly viewed as a commodity to be bought and sold, and illicit informal monetary payments are now commonplace. The result is that nepotism, cronyism, bribery and corruption hinder meritocratic processes.Research limitations/implications– This paper examines the prevalence and nature ofblatin just one sector in one post-Soviet country. An analysis across a wider range of sectors in various post-Soviet societies is now required to develop a more context-bound and nuanced understanding ofblatin post-Soviet societies.Originality/value– This is the first in-depth empirical evaluation of the prevalence and nature ofblatin contemporary post-Soviet societies.
