Leisure-tourism connection behaviors by life stage and gender
Authors: Chang Seohee , Chung Gi Eun 
Published: September 2018

Purpose
Individuals’ daily leisure activities undertaken close to home often appear in tourism contexts when individuals are away from home. Previous studies have suggested that such leisure-tourism connection behaviors are enhanced by leisure involvement and leisure habits. However, few studies have examined if such a connection may have variations by life stage and gender. Therefore, this study aims to examine the roles of life stage and gender in consistency between leisure and tourism, in consideration of involvement and habit. The study samples were university graduates (n = 681) who had graduated from a university in the United States and were currently working and university students (n = 706) who were enrolled and taking classes at a university in the United States.

Design/methodology/approach
Data were analyzed using descriptive analysis, exploratory factor analysis, t-test, two-way ANOVA and multiple regression analysis.

Findings
The findings revealed differences in the effects of leisure involvement and habit factors on the leisure-tourism connection behaviors by life stage and gender. More details are presented in this paper.

Originality/value
This study is the first study to examine the leisure-tourism connection behaviors in consideration of life stage and gender.
Chaos theory, uncertainty, and organizational learning
Authors: Keyes Laura M. , Benavides Abraham David 
Published: September 2018

Purpose
The purpose of this paper is to juxtapose chaos theory with organizational learning theory to examine whether public organizations co-evolve into a new order or rather institutionalize newly gained knowledge in times of a highly complex public health crisis.

Design/methodology/approach
The research design utilizes the results from a survey administered to 200 emergency management and public health officials in the Dallas–Fort Worth metroplex.

Findings
The findings of this paper suggest that public entities were more likely to represent organizational learning through the coordination of professionals, access to quality information, and participation in daily communication. Leadership was associated with the dissemination of knowledge through the system rather than the development of new standard operating procedures (as suggested by chaos theory and co-evolution).

Research limitations/implications
There are limitations to this study given the purposive sample of emergency management and public health officials employed in the Dallas–Fort Worth metroplex.

Practical implications
The authors find that public organizations that learn how to respond to unprecedented events through reliance on structure, leadership, and culture connect decision makers to credible information resulting in organizational learning.

Social implications
As a result, public administrators need to focus and rely on their organization’s capacity to receive and retain information in a crisis.

Originality/value
This research contributes to our understanding of organizational learning in public organizations under highly complex public health situations finding decisions makers rely on both organizational structure and culture to support the flow of credible information.
Digitalisation in the banking industry and workers subjective well-being
Authors: Umans Timurs , Kockum Martin , Nilsson Elin , Lindberg Sofie 
Published: September 2018

PurposeThe purpose of this paper is to explore how bankers perceive digitalisation relating to their subjective well-being. The paper seeks to further explore how this relation is contingent on the aspect of structural organisation represented by the concept of individualist/collectivist organisational culture.Design/methodology/approachThe study is based on the survey distributed to employees of 18 bank offices in the south of Sweden, which 161 employees answered. The analysis of the data was performed by descriptive statistics, principle component analysis, Pearson correlations, multiple linear and moderating multiple linear regression analyses.FindingsThe study indicates that bankers’ experience digitalisation as a four-faceted construct: a tool for information management, and work optimisation, customer relation management and as a change agent. The study suggests that the use of digital tools for work optimisation has a positive relation to the work- related dimensions of subjective well-being as well as a spillover effect on the life balance and life satisfaction dimensions. It also indicates that the information management dimension has a positive relation to the life satisfaction aspect of subjective well-being. Finally, the study found that increasing the degree of collectivist organisation culture has a positive moderating effect on the relation between the use of digital tools for work optimisation and life balance and subjective well-being, respectively.Originality/valueThe study reveals a new way of operationalising digitalisation in banks and is the first study of its type to explore the relationship between digitalisation different facets and banker subjective well-being.
Taguchi approach to erosion wear optimization of WC-10Co-4Cr sprayed austenitic steel subjected to equisized slurry
Authors: Singh Gurmeet , Kumar Satish , Sehgal Satbir S. 
Published: September 2018

PurposeThis paper aims to optimize the erosion wear analysis of slurry impeller material. Stainless steel (SS-410) was used as the pump impeller material. This erosion test was established to influence the rotational speed, solid concentration, time period and particle size. Fly ash was used as the erodent material.Design/methodology/approachThe erosion wear experiments were performed at different particle size, rotational speed, time duration and solid concentration (by weight). These tests were performed at four different speeds of 750, 1,000, 1,250 and 1,500 rpm, and the time durations of these experiments are 75, 120,165 and 210 min. For protective coating, high-velocity oxygen-fuel spray process was used for depositing WC-10Co-4Cr coating on stainless steel. To investigate the influence of controlled process parameters on slurry erosion wear of pump impeller material, Taguchi method was used.FindingsResults show that significant improvement in erosion wear resistance has been observed by using WC-10Co-4Cr coating. The process parameters affecting the erosion wear loss were in following order: time > rpm > concentration > particle size. The means of signal-to-noise ratio of stainless steel SS410 with and without coating vary from 93.56 to 54.02 and from 86.02 to 48.18, respectively.Originality/valueFor the erosion wear rate of both uncoated and coated stainless steel, the most powerful influencing factor was identified as time. The erosion test reveals that the coating exhibits ductile erosion mechanism and shows better erosion wear resistance (approximately two times) compared to uncoated stainless steel.
Influence of piezo-viscous behavior and load on the effectiveness of inlet zone bump in unidirectional pure sliding EHL line contacts
Authors: Kumar Punit 
Published: September 2018

Purpose
The purpose of this paper is to introduce the concept of stationary inlet zone bump (IZB) for film thickness enhancement in unidirectional pure sliding elastohydrodynamic lubrication (EHL) line contacts and to investigate the effects of maximum Hertzian pressure (load) and piezo-viscous response on the effectiveness of IZB.

Design/methodology/approach
The numerical analysis involves the solution of Reynolds and elasticity equations. The well-established Doolittle–Tait equations are used herein to determine the lubricant viscosity and density as functions of local pressure, while the Carreau model is used to describe the lubricant rheology. The IZB is assumed to have a sinusoidal profile and it is present on the stationary surface. The governing equations are discretized using finite difference scheme and solved using the Newton–Raphson technique.

Findings
Two test oils, L7808 and SR600, with linear and exponential piezo-viscous responses in the inlet zone are considered here for comparison. The effectiveness of IZB in terms of film thickness enhancement is found to be more for SR600. Besides, IZB is found to be more effective at lower values of maximum Hertzian pressure. The bump needs to shift downstream at higher load to be as effective as at lower load.

Originality/value
This is the first paper to simulate EHL characteristics in the presence of a stationary IZB and to study the effect of various parameters on EHL effectiveness. The film thickness enhancement obtained here is remarkable and hence it is a novel and valuable contribution.
Asymmetry characteristic of tilting-pad thrust bearing during the start-up and shut-down process
Authors: Wang Zhanchao , Guo Fei , Liu Ying , Liu Xiangfeng , Wang Yuming 
Published: September 2018

Purpose
This aim of this paper has been to investigate the squeeze effect of a water-lubricated tilting-pad thrust bearing during start-up and shut-down periods.

Design/methodology/approach
In this paper a numerical model with a squeeze and slippage effect was adopted to analyse the asymmetry characteristic of a tilting-pad thrust bearing during start-up and shut-down periods. A test rig was built to verify numerical results, which were a combined measurement method in which acceleration sensor and torque sensor were used simultaneously to determine the angle change of the thrust pad.

Findings
It was found that as the velocity gradient increased, the difference of the minimum dimensionless film Hmin could be ignored in the start-up process. But in the shut-down process, as the velocity gradient increased, the value of Hmin also increased, which showed that there was an asymmetry characteristic of the tilting bearing in two processes. This phenomenon was verified by measuring the friction torque curve in the test.

Originality/value
The results of the studies demonstrated that the velocity gradient could be designed to reduce the friction of the thrust bearing, which would be beneficial to the working life of the tilting-pad thrust bearing.
Experimental study on wet skid resistance at different water-film thicknesses
Authors: Jiao Yunlong , Liu Xiaojun , Liu Kun 
Published: September 2018

Purpose
Driving safety on a wet road is closely related to the wet skid resistance of tires. The purpose of this paper is to reveal the evolution of wet skid resistance at different water film thicknesses and provide some guidance on the design of a tread pattern with improved traction on rainy roads.

Design/methodology/approach
Brake tests are performed in a laboratory with a viscoelastic tribotester at various water film thicknesses. The initial water film thickness is 3 mm, which decreases with an increase in the test number. Brake friction force is dynamically measured at water film thicknesses ranging from 0 mm to 3 mm.

Findings
The results show that water film thickness exerts a great influence on the forms of tire motion and slip ratio. The tire is much easier to slide on the road with thick water film and also with a considerably thin water film (about 0-1 mm) during a sharp braking process. The brake traction can be very low under this road condition despite the apparently safe quality of the road.

Originality/value
The authors design and establish a new viscoelastic tribotester which is used to simulate the real braking sliding process and study the tribological properties between tire rubber and road surface. The variation in the wet friction coefficient and slip ratio at different water film thicknesses have a great influence on the design of a tread pattern with improved traction on rainy roads.
The size effect of hexagonal texture on tribological properties under mixed lubrication
Authors: Zheng Long , Gao Yihang , Zhong Yinghui , Lu Guolong , Liu Zhenning , Ren Luquan 
Published: September 2018

Purpose
The purpose of this study is to elucidate the size effect (groove width, unit length and area density) of the hexagonal texture on tribological properties under lubrication.

Design/methodology/approach
The tribological properties of nine hexagonal textures with different hexagon lengths and groove widths have been investigated under mixed lubrication to elucidate the size effect.

Findings
Overall, the friction coefficient decreases as the groove width increases within the examined range, whereas the hexagon length shows an optimal value around 3 mm. In particular, one hexagonal texture (3 × 3 mm) exhibits lower friction coefficients and less wear losses than the others. Interestingly, two hexagonal textures of similar area density (1 × 1 mm and 3 × 3 mm) yield the worst and best tribological performances, respectively, which can be explained by the simulated distribution of equivalent stress.

Originality/value
The tribological properties of nine hexagonal textures are examined under lubrication. The 3 × 3 texture exhibits lower friction coefficient and wear loss than the others. Two textures of similar area density yield the worst and best tribological performances. The results agree with the simulated distribution of equivalent stress.
The salesperson wellness lifestyle, coping with stress and the reduction of turnover
Authors: Kraft Frederic B. , Maity Devdeep , Porter Stephen 
Published: September 2018

PurposeIt is well known that job stress is major cause of salesperson job dissatisfaction and turnover. Salespeople require the resources to cope adequately with a multitude of job stressors, and the purpose of this study is to demonstrate that salesperson wellness promotes the ability of salespeople to use effective coping strategies in the workplace and as a result decrease their intentions of leaving the firm.Design/methodology/approachData including measures of coping strategies and a wellness lifestyle orientation were collected from a sample of 441 full-time professional salespeople in two metropolitan statistical areas of the USA. Structural equation modeling was used to demonstrate the relationship of a wellness lifestyle to coping strategies and in turn the relationship of coping strategies to job satisfaction and turnover intentions.FindingsThe study demonstrated the influence of the wellness lifestyle on salespeople’s ability to cope effectively with job stress. It extends previous research by demonstrating the direct influence of salesperson wellness on coping behaviors and demonstrates the nomological validity of the wellness lifestyle construct by modeling its relationship with job satisfaction and the intent to leave the organization.Research limitations/implicationsThe study recommends new research on the synergies that might be produced by simultaneous consideration of the social, physical, and psychological elements of the multicomponent wellness lifestyle. This should be particularly valuable in the context of the Challenger Sale.Practical implicationsWellness programs may be introduced or improved following an assessment of coping resource weaknesses of the sales force. New employees could be screened by examining their wellness profiles.Originality/valueMajor firms have promoted wellness lifestyle programs for years, but no studies have examined the influence of such programs on coping with job stress by salespeople. The paper demonstrates the value of the salesperson wellness lifestyle by showing that it promotes the most adjustive form of coping strategy, problem-focused coping.
Impact of underwriting insurance risk on bank holding company behavior
Authors: Gupta Manu , Prakash Puneet 
Published: September 2018

Purpose
This paper aims to study differences in risk behavior between holding companies that undertake both banking activity and insurance underwriting (labeled financial holding companies or FHCs) and stand-alone bank holding companies (BHCs).

Design/methodology/approach
The paper examines the discretionary accruals of FHCs to comparable BHCs and compares their bad loans-to-assets ratio in the future.

Findings
FHCs have lower discretionary accruals (loan loss provisions and realized capital gains) than BHCs. FHCs fare better than BHCs in terms of bad loans-to-assets ratio. Insurance underwriting has a dampening effect on discretionary accruals of FHCs.

Research limitations/implications
This study raises additional research questions. Do shared governance and insurance underwriting serve as substitutes or complements? Will regulatory environment affect this relation?

Practical implications
When reported earnings do not match true earnings, the market participants lose the ability to price correctly, and the regulators lose the ability to effectively regulate banks. From the regulatory perspective, these findings suggest insurance underwriting by banks mitigate potential market distortions.

Originality/value
This paper is the first to study the effect of underwriting insurance risk on earnings management behavior of BHCs and its link to risk governance.
Lean production system development through leadership practices
Authors: Toledo Jose Carlos , Gonzalez Rodrigo Valio Dominguez , Lizarelli Fabiane Letícia , Pelegrino Renato Arima 
Published: September 2018

Purpose
Although lean methods are considered easy to be implemented during the initial phases of the lean transformation process, few companies are able to maintain them in long term. One of the key factors for this maintenance is the role played by the leaders in their teams. The purpose of this paper is to show the outcomes of an action research that analyzed and developed leadership practices, using the lean leadership model for developing people as reference and considering the factors: to promote employees’ self-development; to coach and develop employees; to support daily kaizen; to create vision and align goal.

Design/methodology/approach
The results of this study are based on the action research method applied in a large Brazilian industrial company. The study was structured considering the phases of problem diagnosis, action plan, implementation and evaluation of practical and theoretical results.

Findings
The leadership practices implemented from the model were shown to be adequate to the lean production system (LPS) and it was observed that reflecting on the processes and the organizational learning are two main concepts that these practices support in the organization.

Research limitations/implications
Since this study is based on action research in a single company, the generalization of results is limited. Suggestions for future research include the development of a quantitative research in different industrial contexts.

Practical implications
The practical implications of this research are to present activities that must be developed by the leadership of organizations to maintain LPS.

Originality/value
This paper raises the problems of organizational leadership that limit the implementation and maintenance of LPS, presenting the planning and implementation of changes in leadership practices to solve these problems.
Street food: factors influencing perception of product quality
Authors: Morano Rogerio Scabim , Barrichello Alcides , Jacomossi Rafael Ricardo , D’Acosta-Rivera Jorge Ramon 
Published: September 2018

Purpose
The purpose of this study is to evaluate whether the perceptions of cleanliness and organization of the point of sale, hygiene and training of those who serve the public (service) and healthiness of the products, constitute a base for the perception of the quality of food sold in the street. Studies about development of street food trade have gained relevance in academic debate because of its social and economic significance. Usually, aspects related to sanitary issues are presented, and the factors that influence consumer perception regarding quality of food consumed are less explored. This was the focus of this work. The relationships among possible predecessors – attendance, cleanliness, organization and healthiness – were tested, all acting together, influencing the variable perception of product quality. Competitive models were tested because of theoretical divergences regarding the relationship between quality and healthiness, not yet totally clear in the literature.

Design/methodology/approach
A quantitative survey was carried out in the city of Diadema (SP, Brazil), getting 603 respondents, with data and theoretical models analyzed by structural equation modeling.

Findings
Results indicated that organization variable is not significant regarding perception of product quality, while attendance and healthiness directly affect this perception. On the other hand, cleanliness influences perceived healthiness and this, in turn, reinforces perception of product quality.

Practical implications
The focus of street food traders should be on clerk cleanliness and politeness (characteristics related to the service) that end up influencing the perception that the consumer develops regarding healthiness (characteristic related to product quality).

Originality/value
Usually research studies on this theme include only aspects related to sanitary and safety issues, and those which focus on consumer perception of food quality cover conventional outlets such as bars and restaurants. There are few ones performed as in this study that analyze street food consumer behavior regarding his/her perception of quality, cleanliness, care received, among others.
Ontogenetic shifts in plant ecological strategies

Published: September 2018

Abstract

Ontogenetic shifts in plants are ubiquitous, but their ecological and evolutionary significance remain largely unknown. Juveniles have few opportunities to accumulate sufficient biomass to withstand damage, whereas adults allocate resources to reproduction. Thus, age‐specific environmental filters are expected to drive selection towards specific resource‐investment strategies for each developmental stage.

We tested whether species exhibited strategies that favour faster rates of biomass accumulation during early developmental stages to cope with vulnerability, shifting towards habitat‐dependent strategies to optimise resource acquisition and use later on. We also hypothesised that juveniles exhibit greater intraspecific variability of strategies than adults, as a result of continuous filtering of traits throughout the plant’s development towards adulthood.

We measured key leaf traits—leaf area (LA), leaf dry matter content (LDMC) and specific leaf area (SLA)—and calculated scores for competitor (C), stress‐tolerator (S), ruderal (R) strategies of the CSR system for juveniles of 54 species and conspecific adults of 27 species naturally occurring either in unproductive (grassland) or productive (forest) habitats.

Juveniles exhibited higher SLA and LA and lower LDMC, and thus a more R‐strategy in both habitats when compared with adults, but were not necessarily “R” in absolute terms. We also found smaller intraspecific variation for the R‐strategy in adults compared with juveniles in both habitats, whereas the variation of the other strategies was habitat dependent.

Ontogenetic shifts in ecological strategies appear to have been selected as a response to ontogeny‐dependent filters. Thus, strategies that favour less costly leaves and faster growth rates (relatively R‐selected) in juveniles shift towards C and/or S strategies in adulthood, depending on habitat productivity. Nevertheless, habitat‐dependent specialisation seems to be a major driver of ecological strategy selection in juveniles. Our study reveals ontogeny‐dependent strategies, offering a new approach to integrate plant development and functional specialisation.
