Further exploration of subjective knowledge in the wine sector
Authors: Canziani Bonnie , Hwang Jiyoung , Byrd Erick T. 
Published: September 2016

Purpose
This paper aims to discuss methodological issues with the measurement of subjective wine knowledge (SWK). The current study offers deeper insights into the relationship between SWK and consumer perceptions of benefits and purchase/consumption habits.

Design/methodology/approach
An empirical study of US winery visitors was conducted, comprising surveys using a structured self-administered written questionnaire and trained field researchers. A sample of 734 surveys was used in subsequent exploratory and confirmatory analysis of the relationships between SWK and an array of consumer perceptions and wine consumption behaviors.

Findings
The majority of respondents were older, female, more highly educated, of the professional or executive class and possessing higher incomes. Slightly over half of the sample professed no or basic knowledge of wine and grape types or wine regions and geography. In general, respondents rated personal benefits of wine consumption higher than they did symbolic or social benefits. The level of SWK, from novice to advanced, was significantly and positively associated with the frequency of visits to wineries (experience), with wine-focused published external information sources and with a majority of perceived benefits.

Originality/value
The primary value of the study is to support marketing strategy by addressing the measurement of SWK. Knowledgeable consumers recognize more types of benefits, i.e. personal, symbolic and social and, thus, can more readily attest to value in a wine offering.
Investigation to study the applicability of solid lubricants in machining for clean and green manufacturing
Authors: Makhesana Mayurkumar Ashwinbhai , Patel Kaushik M. 
Published: September 2016

Purpose
The quality of the surface being machined and tool life are greatly affected by heat generated during machining. Abundant use of cutting fluid leads to higher production rates and a threat for environment and worker’s health. Hence, the need is to identify eco-friendly lubricants. The purpose of the current work is to investigate the effects of solid lubricants (boric acid and molybdenum disulphide) mixed with oil during turning of EN-31 using cemented carbide tools. The concentration of solid lubricants in oil is varied to analyze output parameters such as surface roughness, process temperature, power consumption and tool wear.

Design/methodology/approach
EN 31 steel material is machined at various cutting speeds and constant feed and depth of cut to determine the effects of dry, wet and solid lubricant assisted machining.

Findings
Experimental study revealed that the solid lubricants performed better while machining and therefore it may be considered as environment friendly and cost effective way of lubrication as compared to flood cooling.

Research limitations/implications
The work can be extended to identify the effects of solid lubricants on micro hardness and cutting force.

Practical implications
From the findings of the work, solid lubricants may be considered as suitable choice as compared to fluid cooling because it improves process performance without much affecting the environment and worker’s health.

Originality/value
So far the use of solid lubricants in machining is limited. The results of the work will be useful to explore various efficient way to apply solid lubricants.
Numerical analysis on the static performance of a new piezoelectric membrane restrictor
Authors: Liu Zichao , Pan Wei , Lu Changhou , Zhang Yongtao 
Published: September 2016

Purpose
This paper aims to establish an accurate mathematical model of a piezoelectric membrane restrictor that can be applied to control the shaft’s centerline orbit.

Design/methodology/approach
The methodology uses three coupled equations to establish a mathematical model of the piezoelectric membrane restrictor – Reynolds equation, the membrane deformation equation and the flow rate equation. A data identification method is used to propose the flow rate formulas for the piezoelectric membrane restrictor.

Findings
It has been found that the structural parameters, the membrane center deformation and the inlet and outlet pressures of the piezoelectric membrane restrictor have an effect on the static performance of the restrictor. The identified flow rate result of the piezoelectric membrane restrictor is consistent with the models.

Originality/value
The paper provides an accurate mathematical model of the piezoelectric membrane restrictor which can also be applied to other membrane restrictors.

Authors: Huang Fuchuan , Deng Fukang , Li Kang-Chun , Qin Ke 
Published: September 2016

Purpose
Aiming at the high temperature, high speed, high precision and high surface quality of the copper belt cold rolling, the purpose of this paper is to develop a new type of lubricant for cold rolled copper belt.

Design/methodology/approach
The component of the developed oil was determined based on the physical and chemical properties of the base oil and the tribological properties, the oxidation resistance properties, the rust resistance properties, the anti-foam properties, the demulsibility and the other properties of the additives. The orthogonal experiment method was used to determine the optimum adding amount of the additives; finally, the developed oil formulation was determined.

Findings
The physical and chemical experiment results show that the developed oil has a good performance of oil film bearing capacity and oxidation resistance. The simulation of rolling experiment found that the developed oil can significantly reduce rolling pressure and effectively reduce the friction in the process of rolling.

Originality/value
The experimental results show that the developed oil has excellent performance and can meet the requirement of lubrication in the process of cold rolling copper belt.
Biotribological behaviour of Vitamin E-blended highly cross-linked UHMWPE in a hip joint simulator
Authors: Chen Guomei , Ni Zifeng , Qian Shanhua , Zhao Yongwu 
Published: September 2016

Purpose
The purposes of this paper are to investigate the biotribological behaviour of Vitamin E-blended highly cross-linked ultra-high molecular weight polyethylene (HXL-UHMWPE) under multi-directional motion by using a CUMT II artificial joint hip simulator and compare it with HXL-UHMWPE and conventional UHMWPE.

Design/methodology/approach
The biotribological behaviour of conventional, highly cross-linked and Vitamin E-blended highly cross-linked UHMWPE acetabular cups counterfaced with CoCrMo alloy femoral head under multi-directional motion were investigated by using CUMT-II artificial hip joint simulator for one-million walking cycles. The test environment was at 36.5 ± 0.5°C and 25 per cent bovine serum was used as lubricant. A Paul cycle load with a peak of 784 N was applied; the motion and loading were synchronized at 1 Hz.

Findings
The wear resistance of Vitamin E-blended highly cross-linked UHMWPE was significantly higher than that of highly cross-linked and conventional UHMWPE. The wear marks observed from the worn surface of UHMWPE were multi-directional, with no dominant wear direction. Only abrasion occurred on the surface of Vitamin E-blended highly cross-linked UHMWPE, while yielding and accumulated plastic flow processes occurred on the surface of conventional UHMWPE and flaking-like facture and abrasion occurred on the surface of highly cross-linked UHMWPE.

Originality/value
Besides the prevention of oxidative degradation, blending with Vitamin E can also reduce the incidence of fatigue crack occurred in the surface layer of HXL-UHMWPE samples. Therefore, the wear resistance of HXL-UHMWPE under multi-directional motion can be further enhanced by blending with Vitamin E.
Web-based and face-to-face classes: are there unintended outcomes?
Authors: Burch Gerald , Heller Jacob A. , Burch Jana J. , Heller Nathan A. 
Published: September 2016

Purpose
Empirical research has demonstrated that web-based classes offer similar learning outcomes as face-to-face classes. The purpose of this paper is to examine the unintended effects of delivery method (web-based or face-to-face) on student learning, competency development, and student engagement.

Design/methodology/approach
Exam grades and a survey were collected from 180 undergraduate business students at a public university in the Southern USA. All students were enrolled in the same course, taught by three instructors.

Findings
One-way analysis of variance of the mean showed that declarative and procedural knowledge attained was not statistically significantly different for web-based or face-to-face instruction. However, students in the face-to-face sections reported higher attainment of cognitive intelligence competencies, social intelligence competencies, overall student engagement, emotional engagement, cognitive engagement in class, and cognitive engagement out of class although these outcomes were not specifically targeted as learning outcomes.

Research limitations/implications
Research participants all came from one course, at one university.

Practical implications
There are potentially beneficial, unintended outcomes associated with face-to-face courses. Web-based learning courses may require a redesigned approach that addresses these benefits by adding course elements and tasks that increase student engagement and creates opportunities for development of cognitive and social intelligence competencies.

Originality/value
Little research has been conducted on unintended learning outcomes such as competency development and student engagement. Therefore, this study demonstrates that educators should consider factors beyond learning assessment when comparing web-based to face-to-face courses.
The role of vision in organizational readiness for change and growth
Authors: Haque MD , TitiAmayah Angela , Liu Lu 
Published: September 2016

PurposeThe purpose of this paper is to use path analysis to test a model that posits that vision will have both direct relationships with organizational growth and indirect relationships to organizational growth through the mediating effects of organizational readiness for change.Design/methodology/approachThe population of the study consisted of 104 fully or partially employed business students from a higher education institution located in Southern California. The data were gathered by questionnaires and analyzed by path analysis to test the hypothesized model.FindingsThe results suggested that perceived readiness for change mediates the relationship between vision attributes and organizational growth. Also, there was a direct impact of vision content (VC) on organizational growth. Perceived readiness for change did not mediate the relationship between VC and organizational growth or the relationship between vision communication and organizational growth.Practical implicationsThe study makes contributions to both theory and practice. From a theoretical point of view, examining the relationship between organizational vision and perceived organizational readiness for change enriches the understanding of the organizational change process, and in turn enhances organizational performance and growth. In addition, the authors add to existing knowledge by empirically investigating the important role that vision and employees’ readiness for change play in organizational success.Originality/valueDespite many scholars emphasizing the significance of a vision on organizational readiness for change and organizational growth, there is little empirical research that substantiates this assumption. Therefore, this empirical study appears to be the first to explore the idea.
From creative process engagement to performance: bidirectional support
Authors: Du Yana , Zhang Li , Chen Yanhong 
Published: September 2016

PurposeThe purpose of this paper is to explore the effect of creative process engagement on employees’ in-role performance, and does so by considering the support that employees received from and given to their supervisors.Design/methodology/approachUsing data from 540 questionnaires collected in China, this paper conducts a hierarchical regression analysis to test the proposed model.FindingsCreative process engagement positively affects employees’ in-role performance. However, the moderating effect of receiving support on the above relationship is not significant. Instead, it is the interaction of receiving support from and giving it to supervisors that moderates the relationship between creative process engagement and in-role performance.Research limitations/implicationsThe study has some contributions to the conservation of resource (COR) theory. The authors find that acquiring new resources such as receiving support from supervisors is not always effective. The acquisition process of resources should be considered with the investment process of resources. According to the COR theory, people invest resources to gain resources and protect themselves from losing resources or to recover from resource loss (Halbeslebenet al., 2014). The findings of the study show that employees investing resources is not just for gaining resources. Sometimes, they invest resources such as giving support to supervisors to remain a relatively balanced relationship.Practical implicationsCompanies can encourage employees to place more attention on creative process engagement to improve in-role performance. In addition, when offering support to employees, managers should consider whether the employees are able to give it back in response to the received support, and distribute their support to employees accordingly.Originality/valueThis paper explored employee’s engagement at creative process in a more novel way and clarified the relative effect of creative process engagement on in-role performance. Also, this paper was the first to pay attention to the bidirectional nature of supervisor support.
Supervisory servant leadership and employee’s work role performance
Authors: Otero-Neira Carmen , Varela-Neira Concepción , Bande Belén 
Published: September 2016

Purpose
The purpose of this paper is to explore whether employee’s perceived organizational support and organizational identification (OID) have a mediating role in the relationship between supervisor’s servant leadership and employee’s organization member performance.

Design/methodology/approach
The sample used in this study consists of 181 salespeople and 83 sales managers. The model entails a cross-level mediation process that was tested using dyadic data and multilevel structural equation modeling.

Findings
Findings show that sales managers’ servant leadership is directly and positively related to salespeople’s organization member performance. In addition, sales managers’ servant leadership is indirectly related to salespeople’s organization member performance through the salespeople’s perceived organizational support – salespeople’s OID chain.

Practical implications
In order to increase employee’s organizational member performance, employees with a “we” mentality and who feel the need to serve should be selected for and promoted to supervisors. To enhance employees’ perceived organizational support and OID is also important, as these factors will encourage employees to behave in the best interest of the organization.

Originality/value
This is the first study to provide evidence for the relationship between servant leadership and organization member performance, as well as the mediating roles of employee’s perceived organizational support and OID on this relationship.
Assessment centers vs situational judgment tests: longitudinal predictors of success
Authors: Blair Carrie A. , Hoffman Brian J. , Ladd Robert T. 
Published: September 2016

Purpose
The purpose of this paper is to provide an empirical comparison of a high-fidelity managerial simulation, assessment center (AC) ratings, to that of a lower fidelity managerial simulation, a video situational judgment test (SJT) in the prediction of manager career success.

Design/methodology/approach
Archival data were collected from a large utility company. A measure of general mental ability (GMA), an SJT, and an AC were examined as predictors of career success as measured by increases in salary.

Findings
The AC and the video SJT used in this study appeared to assess different constructs, extending previous findings that ACs and written SJTs measure distinct constructs. Furthermore, the AC dimensions and the SJT remained valid predictors of salary over a six year span following the test administration. In addition, the AC explained significant incremental variance beyond GMA and SJTs in career success six years after the assessment.

Research limitations/implications
The SJTs and AC used in this study are similar in psychological fidelity, yet the ACs remained a more valid predictor over time. The recommendation is that lower fidelity simulations should not be used as prerequisites for higher fidelity simulations.

Practical implications
The results lend general support to the value of high-fidelity instruments in predicting longitudinal success.

Originality/value
The paper offers a comparison of the validity of ACs and video SJTs.
Why does leader attention scope matter for innovation ambidexterity? The mediating role of transformational leadership
Authors: Zheng Xiaofeng , Liu Zhiying , Gong Xiuyuan 
Published: September 2016

PurposeThe purpose of this paper is to explore the role leader attention plays in the nurture of transformational leadership (TL) behavior, as well as the mechanism by which TL affects innovation ambidexterity, this research empirically studied the relationship between leader attention scope (LAS) and innovation ambidexterity (exploratory innovation and exploitative innovation) through the mediating role of TL. Further, the moderating effect of environmental dynamism (ED) on the relationship between TL and innovation ambidexterity was examined.Design/methodology/approachEmpirical study was adopted by distributing questionnaires to high echelon leaders in mainland China to assess related variables. Structural equation modeling was used to examine the relationships of the variables based on the 188 returned questionnaires.FindingsThe results show that LAS had a positive effect on innovation ambidexterity, and the relationship was partially mediated by TL. ED negatively moderated the relationship between TL and innovation ambidexterity.Practical implicationsThe results suggest that upper echelon leaders receive more unfamiliar, outward-oriented, and source-diverse information to broaden their attention scope. The broad outlook they get obliges them to engage in TL behavior which is beneficial for innovation ambidexterity.Originality/valueBased on upper echelons theory, this research reveals the realization mechanism of innovation ambidexterity from the perspectives of leader attention and leadership behavior. This paper avoids the previous research limitation of prevalently employing demographic measurements to substitute for leaders’ psychological processes. The study of LAS also explains the formation mechanism of TL. ED is considered to examine the effectiveness of TL.
Putting a band-aid on a wooden leg
Authors: Vermeerbergen Lander , Van Hootegem Geert , Benders Jos 
Published: September 2016

Purpose
Decentralisation attempts that aim to increase job autonomy do not always succeed. This paper aims to study to what extent the tendency to maintain existing operational task divisions is an important explanation for this lack of success.

Design/methodology/approach
In total, 456 employees in 25 organisations participated in a cross-sectional intervention study. Each employee filled out a questionnaire on job autonomy both before and after the decentralisation process, in which all organisations shifted regulatory, preparatory and supportive tasks to the lowest organisational level.

Findings
This study found small, but significant, effects of decentralisation attempts on job autonomy. The size of the effects, however, depended on the way the way in which the operational tasks were divided. Simultaneously, larger effects were found for organisations which decentralised tasks and changed the way operational tasks were divided. Both findings reached the conclusion that although decentralisation attempts seemed important for increasing job autonomy, the way in which the operational tasks were divided and even changed, was at least as important for a successful decentralisation process.

Originality/value
After decades of research on modern sociotechnical theory, this study is the first to show that decentralisation attempts do not merely increase job autonomy. The effect of such attempts depends on the way in which operational tasks are divided in organisations.
‘Sometimes, it's easier to write the prescription’: physician and patient accounts of the reluctant medicalisation of sleeplessness
Authors: Moloney Mairead Eastin 
Published: September 2016

AbstractThe medicalisation of sleep is a rich and growing area of sociological interest. Previous research suggests that medicalisation is occurring within the context of physician office visits, but the inner workings remain unclear. This study is the first to provide perspectives on the office visit interaction from both sleepless patients (n = 27) and the physicians (n = 8) who treat them. Analyses of semi‐structured qualitative interviews reveal that sleep‐related conversations are typically patient‐initiated in routine office visits. Physicians and patients conceptualised insomnia as a symptom of another issue (depression), an everyday problem of living (stress) or the result of a natural life process (aging). Lack of sleep was not necessarily linked to daytime impairment. Even though sleep aids were routinely requested and prescribed, patients and physicians consistently expressed attitudes of reluctance toward the use of sedative hypnotics. I call this a case of ‘reluctant medicalisation’ and highlight the liminal space between pathology and normalcy inhabited by patients and physicians. I also build on recent work acknowledging the dynamics between macro and micro levels of medicalisation and illustrate the influence of multilevel ‘engines’ (consumerism, biotechnology, managed care and physicians) in patients’ and physicians’ accounts.A virtual abstract of this paper can be viewed at: https://youtu.be/7uLHOJPHF0I
