Published: September 2020

PurposeDrawing on social identity theory and prosocial behaviour research, this study explores how people's integration of their offline and online social activities through Facebook cultivates their Facebook citizenship behaviour (FCB). It also offers further insight into the underlying mechanism of offline and online social activity integration - FCB relation by investigating people's social identification with their offline and online social groups as possible mediators.Design/methodology/approachBased on social identity theory (SIT) literature, community citizenship behaviour and offline-online social activity integration through Facebook, we developed a conceptual model, which was empirically tested using data from 308 Facebook usersFindingsThe results confirm that the participants' offline-online social activity integration via Facebook is positively linked to their FCB. Further, the integration of offline and online social activity through Facebook positively affects how a person identifies with their offline and online social groups, which in turn causes them to display FCB. In addition, offline/online social identification mediates the integration – FCB relation.Practical implicationsIn practice, it is interesting to see people's tendency towards altruistic behaviours within groups they like to associate themselves with. Those who share their Facebook network with their offline friends can use such network to seek help and support.Originality/valueFrom a theoretical perspective, unlike past research, this study examines how individuals' offline-online social activity integration via Facebook helps them associate with groups. In addition, this study investigates social identification from an offline and online perspective.

PurposeThe interprofessional collaboration is a key practice for providing cancer care. However, the realization of collaboration requires effective leadership and administrative support. In this study, the aim was to analyze healthcare professionals' perceptions of leadership and administrative support (strategic and management) in interprofessional collaboration for developing practices in cancer care.Design/methodology/approachA descriptive survey design was used to collect data from healthcare professionals (n = 350, response rate 33.3%), including nurses, physicians and other professionals participating in patient care in one Finnish cancer center (out of five) in 05/2018–10/2018. The data were analyzed using descriptive and inferential statistics. The instrument focused on leadership in the work unit and administrative support including organization strategy and organizational management.FindingsHealthcare professionals perceived leadership in the work unit, organization strategy and management for the support of interprofessional collaboration as weak. However, the ratings of male respondents and those in leading positions were more positive. The findings indicate that healthcare professionals in the cancer care setting are dissatisfied with the leadership and administrative support.Research limitations/implicationsInterprofessional collaboration, including its leadership, requires systematic and constant evaluation and development.Originality/valueHealthcare leaders in the cancer care setting can use the results to identify factors that might be in need of attention and development in the field of interprofessional collaboration.
Exploring visit intention to India for medical tourism using an extended theory of planned behaviour
Authors: Dash Ajitabh 
Published: September 2020

PurposeThe purpose of this paper is to identify the factors influencing the visit intention of medical tourists to India. This study also attempts to extend the theory of planned behaviour through the integration of perceived risk and facilitating condition.Design/methodology/approachPrimary data were collected from a sample of 326 medical tourists arriving in India through Terminal-3 of Indira Gandhi International Airport (IGI-T3), New Delhi, India, during the months of October–December 2019. Confirmatory factor analysis and structural equation modelling are deployed to analyze the collected data and validate the proposed research model.FindingsThe outputs of this study revealed that perceived financial risk, physical risk, psychological risk and facilitating conditions available in a country are significantly linked to the attitude of a medical tourist. Similarly, facilitating conditions available in a country are significantly related to perceived behavioural control of a medical tourist. Furthermore, it is also revealed that attitude, subjective norm and perceived behavioural control are significantly related to visit intention of medical tourists to India; however, the perceived time risk and performance risk are insignificantly associated with the visit intention.Research limitations/implicationsThis study is restricted to the opinion of 326 sample respondents consisting of medical tourists who arrived in India through IGI-T3, New Delhi, during October–December 2019. In the future, a similar type of study may be conducted in different parts of the country with a relatively larger sample sizeOriginality/valueThis study addresses the need for advancing the knowledge on the factors in determining visit intention of medical tourists towards India. This knowledge will become very crucial for India's medical tourism industry, which is aiming to attain a competitive edge in the global market.
The dividend signaling hypothesis and the corporate life cycle
Authors: Meza Narcisa , Báez Anibal , Rodriguez Javier , Toledo Wilfredo 
Published: September 2020

PurposeThis paper aims to examine the relationship between the dividend signaling hypothesis and a firm's life cycle.Design/methodology/approachThe authors use Dickinson's (2011) methodology to develop a proxy for the firm's stages in its life cycle and to examine the relationship between dividends and future earnings following a nonlinear setting.FindingsUsing a sample of US firms during the 2000–2014 period, the authors find that the signaling hypothesis can be dependent on firm-specific characteristics, such as life cycle stages. The authors report that the relationship between dividend changes and subsequent earnings changes is different for different life stages. They also find that changes in the amount of the dividend provide some information about future earnings, especially during the early (introductory and growth) stages. These results are consistent with the use of earnings or return on assets as the dependent variables in models of earnings expectations.Originality/valueThe authors believe that this is the first time that the dividend signaling hypothesis has been linked to the life cycle of the firm.
Corporate social responsibility and organizational commitment: effects of CSR attitude, organizational trust and identification
Authors: George Nimmy A. , Aboobaker Nimitha , Edward Manoj 
Published: September 2020

PurposeDrawing from the social identity theory and social exchange theory, the purpose of this study is to examine the intervening mechanisms linking perceived corporate social responsibility (CSR) and employees’ affective organizational commitment. It is proposed that organizational trust (OT) and organizational identification (OID) would serially mediate the aforementioned relationship. Furthermore, this paper attempts to understand how employees’ attitude toward the importance of CSR (ICSR), moderates the linkages under the focus of this study.Design/methodology/approachThis descriptive study was conducted among a sample of 519 employees working in the manufacturing sector in India. Self-reporting standardized questionnaires were administered among the respondents, who were selected through the judgment sampling method. Measurement model analysis was done using IBM AMOS 24.0 and Hayes’ PROCESS macro 3.0 (Models 6 and 84) was used for testing the serial mediation and moderated serial mediation.FindingsResults revealed a significant indirect effect of all dimensions of CSR on employees’ affective commitment, serially mediated through OT and OID. The conditional indirect effects varied significantly and it was identified that CSR to customers and CSR to employees had a significant conditional indirect effect on affective commitment, through attitude toward the ICSR, OID and OT. However, the conditional indirect effect of CSR to social and non-social stakeholders on affective commitment was not statistically significant.Originality/valueThis study is pioneering in conceptualizing and empirically testing an integrated theoretical framework that models the influences of perceived CSR, employees’ attitude toward the ICSR, OID and OT on their affective commitment toward the organization. CSR plays a vital role in strengthening the employer-employee relationship and managers should facilitate a work environment that befits the alignment of organizational and individual ethics and values.
Providing strategic leadership for learning: optimizing managerial coaching to build learning organizations
Authors: Ellinger Andrea D. , Ellinger Alexander E. 
Published: September 2020

Purpose
The purpose of this paper and the contribution to this special issue is to build on Kim and Watkins’ (2018) recent finding that ‘leaders mentor and coach those they lead’ is the item in the Dimensions of the Learning Organization Questionnaire (DLOQ) that is most highly-correlated with performance. Given the criticality of providing strategic leadership for learning and, more specifically, the consistent associations between leaders who mentor and coach and work-related performance outcomes, a better understanding of the associations between the learning organization concept and managerial coaching is warranted. Watkins and Kim (2018, p. 22) contend that ‘future directions for learning organization research include a search for the elusive interventions that would create a learning organization’. In response to this call for research, a research agenda for assessing managerial coaching as a learning organization (LO) intervention is proposed.

Design/methodology/approach
This conceptual paper briefly reviews literature on the learning organization and the DLOQ instrument, followed by a more in-depth review of the managerial coaching literature and suggestions for how future research could be conducted that more closely integrates these two concepts.

Findings
Existing literature suggests that to ‘provide strategic leadership for learning’, a dimension in the DLOQ, is one of the most pivotal dimensions for creating learning cultures that build learning organizations. Specifically, an item within this dimension, ‘leaders who mentor and coach’ has been recently identified as one of the most critical aspects associated with strategic leadership for learning.

Originality/value
The extant managerial coaching literature offers a solid foundation for more closely integrating and mainstreaming the developmental intervention of managerial coaching into learning organizations. Directions for future research that identifies fine-grained perspectives of the discrete facets of managerial coaching in learning organization contexts are suggested.
A New Approach to Compute Natural Frequencies and Mode Shapes of One-Dimensional Continuous Structures With Arbitrary Nonuniformities
Authors: Sinha Alok 
Published: September 2020

AbstractOne-dimensional continuous structures include longitudinal vibration of bars, torsional vibration of circular shafts, and transverse vibration of beams. Using the linear time-varying system theory, algorithms are developed in this paper to compute natural frequencies and mode shapes of these structures with nonuniform spatial parameters (mass distributions, material properties and cross-sectional areas) which can have jump discontinuities. A general numerical approach has been presented to include Dirac-delta functions and their spatial derivatives due to jump discontinuities. Numerical results are presented to illustrate the application of these techniques to the solution of different types of spatial variations of parameters and boundary conditions.
Dynamic Analysis of Power Transmission Lines With Ice-Shedding Using an Efficient Absolute Nodal Coordinate Beam Formulation
Authors: Fan Wei , Ren Hui , Zhu Weidong , Zhu Hao 
Published: September 2020

Abstract
Dynamic analysis of power transmission lines with ice-shedding is conducted in this work. The power transmission line is first simplified as a uniform slender round beam. While the beam can have large displacements, rotations, and deformations, its strains are assumed to be small. The bending stiffness of the transmission line is considered here, but its shear and torsion effects are neglected. An efficient absolute nodal coordinate beam formulation is developed based on the above assumptions, and the number of generalized coordinates of each element of the beam is reduced to the least. The mass matrix is constant and the generalized elastic force is evaluated by constant stiffness tensors and generalized coordinates; hence, the current formulation is very efficient. Dynamic responses of power transmission lines with ice-shedding are then calculated. A benchmark planar two-span line is first considered, and the results are validated by the commercial finite element software abaqus. By examining strain states of the transmission line, it is found that its bending stiffness cannot be neglected in this dynamic analysis. Dynamic analysis of a three-dimensional three-span line is then conducted, where towers are not in a straight line and elevation differences between adjacent towers are considered. Several cases with common ice detachment mechanisms are considered, and dynamic responses of the cable and reaction forces of insulators due to ice-shedding are analyzed.
Stability and Hopf Bifurcation of Nearest-Neighbor Coupled Neural Networks With Delays
Authors: Wang Lu , Xiao Min , Zhou Shuai , Song Yurong , Cao Jinde 
Published: September 2020

AbstractIn this paper, a high-dimensional system of nearest-neighbor coupled neural networks with multiple delays is proposed. Nowadays, most present researches about neural networks have studied the connection between adjacent nodes. However, in practical applications, neural networks are extremely complicated. This paper further considers that there are still connection relationships between nonadjacent nodes, which reflect the intrinsic characteristics of neural networks more accurately because of the complexity of its topology. The influences of multiple delays on the local stability and Hopf bifurcation of the system are explored by selecting the sum of delays as bifurcation parameter and discussing the related characteristic equations. It is found that the dynamic behaviors of the system depend on the critical value of bifurcation. In addition, the conditions that ensure the stability of the system and the criteria of Hopf bifurcation are given. Finally, the correctness of the theoretical analyses is verified by numerical simulation.
Investigation of Linear Higher Harmonic Control Algorithm for Rotorcraft Vibration Reduction
Authors: Im ByeongUk , Lee ChangBae , Kee YoungJung , Shin SangJoon 
Published: September 2020

Abstract
A linear quadratic Gaussian (LQG) controller for active vibratory loads reduction in helicopters is proposed based on a revisited higher harmonic control (HHC) input by active trailing-edge flaps (ATEFs). Conventional individual blade control (IBC) input is redefined using N − 1/rev interblade phase lead, N/rev collective, and N + 1/rev interblade phase lag signals where 1/rev frequency modulation originates from the multiblade coordinate (MBC) transform. A Mach-scaled flap blade is designed and analyzed by the multibody dynamics analysis DYMORE. A linear time-invariant representation is identified from N/rev envelopes of the input and output responses obtained by DYMORE analysis. A matlab/simulink closed-loop control simulation is designed using the identified state-space realization. The N/rev vibratory loads are reduced up to 52% with flap deflections and the linear control results match well with the nonlinear responses obtained from DYMORE. Furthermore, the multivariable closed-loop stability estimated by the loop transfer functions using disk margin analysis reveals sufficient gain and phase margins.
Improving Endo-Myocardial Biopsy by Real-Time Spectral Tissue Sensing: A Feasibility Study
Authors: Ali Awaz , Breedveld Paul , Hendriks Benno H. W. 
Published: September 2020

Abstract
The aim of this research is to integrate spectral tissue sensing technology inside a cardiac bioptome for real-time measurements of tissue characteristics. Bioptome tip and handle components were designed and manufactured to house and guide optical fibers. The designed components were assembled on a cardiac bioptome together with optical fibers. A technical feasibility test was carried out to study the functionality of the instrument and the effect of the optical technology on the biopsy performance. Biopsy samples were taken from five different tissue types in a porcine heart and the resulting optical spectra were compared. Spectral tissue sensing fibers were successfully integrated inside a conventional cardiac bioptome. The integrated instrument allowed differentiation between ventricular tissue, blood, and cardiac fat tissue based on blood and fat percentage and amount of scattering. Moreover, differences between scarred and nonscarred tissue were clearly visible. A first step has been made in the use of spectral tissue sensing for the detection of different tissue structures for endo-myocardial biopsy (EMB). The instrument was able to differentiate between various tissues, as well as between healthy and diseased cardiac tissues. Future research should focus on measurements of naturally diseased cardiac tissue, repeated measurements with statistical value, and improvements to the instrument design. Having the ability to measure tissue characteristics prior to acquiring a biopsy sample will not only allow easier positioning of the bioptome at the correct location but can also prevent sampling undesired tissue or scar tissue from previous biopsies.
Estimates of Probability of Detection and Sizing of Flaws in Ultrasonic Time of Flight Diffraction Inspections for Complex Geometry Components With Grooved Surfaces
Authors: Nath S. K. 
Published: September 2020

Abstract
In a reliability assessment of ultrasonic time-of-flight diffraction (TOFD) inspection, probability of detection (POD) and sizing (POS) curves are developed. Experiments are performed on a complex geometry specimen with the grooved inspection surface simulating the gland seal area of a steam turbine rotor. In the reliability experiment, it is assumed and confirmed that the distribution of signal responses is normal. The effects of probe center spacing on detection and sizing are observed. The PODs developed here have a decreasing trend with flaw size which is in contrary to the generally observed increasing trend in conventional ultrasonic amplitude-based flaw sizing techniques. The reason for this decreasing POD with crack height is explained in the present study. The curves developed in this work are specific to the geometry and dimensions of the specimen with the set of notches and the probes used in the experiment. Hence, these curves can only be used under similar conditions. In TOFD inspection of similar type of complex shaped structures, e.g., turbine, the POD and POS curves developed here can be used in taking an appropriate engineering decision with respect to run, repair, or replace.

Authors: Zhu Mengyu , Liu Xintian , Kan Fuchao , You Ziyun 
Published: September 2020

AbstractTo predict the life of the clutch friction plate, friction characteristics of the friction plate and the steel sheet assembly are analyzed in the full life cycle. A contact model of the friction surface is built based on the micro-convex body model. Wear mathematical models of friction plate are established respectively based on the contact model and sliding friction work model. The wear results of the two models are compared and analyzed. The effect of temperature on wear is considered. Fatigue life of the friction plate is predicted by wear mathematical model according to the real working states. The accuracy of the contact model and the influence of temperature on the wear are determined through the comparative analysis of each prediction result.
Hybrid Electromagnetic Shunt Damper for Vibration Control

Published: September 2020

Abstract
It has been shown that shunting electromagnetic devices with electrical networks can be used to damp vibrations. These absorbers have however limitations that restrict the control performance, i.e., the total damping of the system and robustness versus parameter variations. On the other hand, the electromagnetic devices are widely used in active control techniques as an actuator. The major difficulty that arises in practical implementation of these techniques is the power consumption required for conditioners and control units. In this study, robust hybrid control system is designed to combine the passive electromagnetic shunt damper with an active control in order to improve the performance with low power consumption. Two different active control laws, based on an active voltage source and an active current source, are proposed and compared. The control law of the active voltage source is the direct velocity feedback. However, the control law of the active current source is a revisited direct velocity feedback. The method of maximum damping, i.e., maximizing the exponential time-decay rate of the response subjected to the external impulse forcing function, is employed to optimize the parameters of the passive and the hybrid control systems. The advantage of using the hybrid control configuration in comparison with purely active control system is also investigated in terms of the power consumption. Besides these assets, it is demonstrated that the hybrid control system can tolerate a much higher level of uncertainty than the purely passive control systems.
