Reflections on the L’Aquila trial and the social dimensions of disaster risk
Authors: Imperiale Angelo Jonas , Vanclay Frank 
Published: December 2018

PurposeThe purpose of this paper is to reflect on what can be learned about disaster risk reduction (DRR) from the L’Aquila trial of scientists. The court case was initiated because of a controversial meeting on 31 March 2009 of the Major Risks Committee (MRC), held under the auspices of the Italian Department of Civil Protection. The purpose of the meeting was to consider (prior to the fatal earthquake of 6 April 2009) disaster risk in the L’Aquila area, which was being affected by an earthquake swarm since October 2008.Design/methodology/approachThe authors undertook a document analysis of trial materials, and a review of academic and media commentary about the trial.FindingsThe legal process revealed that disaster governance was inadequate and not informed by the DRR paradigm or international guidelines. Risk assessment was carried out only in a techno-scientific manner, with little acknowledgement of the social issues influencing risks at the local community level. There was no inclusion of local knowledge or engagement of local people in transformative DRR strategies.Originality/valueMost previous commentary is inadequate in terms of not considering the institutional, scientific and social responsibilities for DRR as exposed by the trial. This paper is unique in that it considers the contents of the MRC meeting as well as all trial documents. It provides a comprehensive reflection on the implications of this case for DRR and the resilience of peoples and places at risk. It highlights that a switch from civil protection to community empowerment is needed to achieve sustainable outcomes at the local level.
Grey literature archiving pattern in open access (OA) repositories with special emphasis on Indian OA repositories
Authors: Shivaram B.S. , Biradar B.S. 
Published: December 2018

Purpose
This paper aims to examine the grey literature archiving pattern at open-access repositories with special reference to Indian open-access repositories.

Design/methodology/approach
The Bielefeld Academic Search Engine (BASE) was used to collect data from different document types archived by open-access repositories across the world. Data were collected by advanced search and browse features available at the BASE on document types, the number of repositories by country wise and Indian academic and research repositories. Data were tabulated using MS Excel for further analysis.

Findings
Findings indicated that open-access repositories across the world are primarily archiving reviewed literature. Grey literature is archived more at European and North American repositories compared to rest of the world. Reports, theses, dissertations and data sets are the major grey document types archived. In India, a significant contributor to the BASE index with 146 open-access sources, reviewed literature is the largest archived document types, and grey literature is above world average due to the presence of theses and dissertations at repositories of academic institutions.

Originality/value
Grey literature is considered as valuable sources of information for research and development. The study enables to get insights about the amount of grey content archived at open-access repositories. These findings can further be used to investigate the reasons/technology limitations for the lesser volume of grey content in repositories. Furthermore, this study helps to better understand the grey literature archiving pattern and need for corrective measures based on the success stories of repositories of Europe and North America.
Modelling the subjective experience of fun at work
Authors: Clancy Maeve , Linehan Carol 
Published: December 2018

PurposeThe purpose of this paper is to explain some divergent findings on experiences of fun at work. It explains conflicting findings by moving from a focus on classifying the activity (as, e.g. task/managed/organic) to foregrounding the dynamics of the experience, adding to the growing conceptualisation of fun at work as a multi-dimensional construct.Design/methodology/approachThis research draws on empirical data obtained through case study and interviews with 13 participants from two organisations. These interviews were subjected to intense thematic analysis.FindingsIt was found that an individual’s underlying beliefs about the organisation; the perceived drivers of the fun practice; and the level of control exerted over a fun practice significantly shape the experience. The paper draws on the concept of the psychological contract to frame the relationship between these three key interacting elements.Practical implicationsThis paper provides a greater understanding of the dynamics of fun experiences, enabling management to better recognise and contextualise the impact of fun practices.Originality/valueGiven conflicting findings on both the experience and outcomes of fun at work, this study elucidates the dynamics underpinning the experience of fun at work. It is novel to consider experiences of fun through the lens of psychological contracts, which offers fresh insight into the understanding of individual experiences of fun.
Effect of wall-mounted V-baffle position in a turbulent flow through a channel
Authors: Menni Younes , Azzi Ahmed , Chamkha Ali J. , Harmand Souad 
Published: December 2018

Purpose
The purpose of this paper is to carry out a numerical study on the dynamic and thermal behavior of a fluid with a constant property and flowing turbulently through a two-dimensional horizontal rectangular channel. The upper surface was put in a constant temperature condition, while the lower one was thermally insulated. Two transverse, solid-type obstacles, having different shapes, i.e. flat rectangular and V-shaped, were inserted into the channel and fixed to the top and bottom walls of the channel, in a periodically staggered manner to force vortices to improve the mixing, and consequently the heat transfer. The flat rectangular obstacle was put in the first position and was placed on the hot top wall of the channel. However, the second V-shaped obstacle was placed on the insulated bottom wall, at an attack angle of 45°; its position was varied to find the optimum configuration for optimal heat transfer.

Design/methodology/approach
The fluid is considered Newtonian, incompressible with constant properties. The Reynolds averaged Navier–Stokes equations, along with the standard k-epsilon turbulence model and the energy equation, are used to control the channel flow model. The finite volume method is used to integrate all the equations in two-dimensions; the commercial CFD software FLUENT along with the SIMPLE-algorithm is used for pressure-velocity coupling. Various values of the Reynolds number and obstacle spacing were selected to perform the numerical runs, using air as the working medium.

Findings
The channel containing the flat fin and the 45° V-shaped baffle with a large Reynolds number gave higher heat transfer and friction loss than the one with a smaller Reynolds number. Also, short separation distances between obstacles provided higher values of the ratios Nu/Nu0 and f/f0 and a larger thermal enhancement factor (TEF) than do larger distances.

Originality/value
This is an original work, as it uses a novel method for the improvement of heat transfer in completely new flow geometry.

Authors: Menni Younes , Azzi Ahmed , Chamkha A. 
Published: December 2018

Purpose
This paper aims to report the results of numerical analysis of turbulent fluid flow and forced-convection heat transfer in solar air channels with baffle-type attachments of various shapes. The effect of reconfiguring baffle geometry on the local and average heat transfer coefficients and pressure drop measurements in the whole domain investigated at constant surface temperature condition along the top and bottom channels’ walls is studied by comparing 15 forms of the baffle, which are simple (flat rectangular), triangular, trapezoidal, cascaded rectangular-triangular, diamond, arc, corrugated, +, S, V, double V (or W), Z, T, G and epsilon (or e)-shaped, with the Reynolds number changing from 12,000 to 32,000.

Design/methodology/approach
The baffled channel flow model is controlled by the Reynolds-averaged Navier–Stokes equations, besides the k-epsilon (or k-e) turbulence model and the energy equation. The finite volume method, by means of commercial computational fluid dynamics software FLUENT is used in this research work.

Findings
Over the range investigated, the Z-shaped baffle gives a higher thermal enhancement factor than with simple, triangular, trapezoidal, cascaded rectangular-triangular, diamond, arc, corrugated, +, S, V, W, T, G and e-shaped baffles by about 3.569-20.809; 3.696-20.127; 3.916-20.498; 1.834-12.154; 1.758-12.107; 7.272-23.333; 6.509-22.965; 8.917-26.463; 8.257-23.759; 5.513-18.960; 8.331-27.016; 7.520-26.592; 6.452-24.324; and 0.637-17.139 per cent, respectively. Thus, the baffle of Z-geometry is considered as the best modern model of obstacles to significantly improve the dynamic and thermal performance of the turbulent airflow within the solar channel.

Originality/value
This analysis reports an interesting strategy to enhance thermal transfer in solar air channels by use of attachments with various shapes

Authors: Sun Jie , Cai Qianyun , Li Tao , Du Lei , Zou Fengyuan 
Published: December 2018

PurposeConsidering two-dimensional features in the body shape classification system cannot fully reflect the three-dimensional (3D) morphological characteristics of human body. The purpose of this paper is to propose a 3D feature based method to characterize and classify the upper body shape of women, and then obtained the corresponding garment block and improved the fitness of clothing.Design/methodology/approachIn this study, the [TC]23D scanner was used to obtain human data, and 15 layers of cross-sections of young females’ upper body were extracted. In total, 240 space vectors were obtained with the center of the bust cross-section as the original point. By using the principal component analysis and K-means clustering analysis, the body shape classification based on the space vectors length was realized. The garment block corresponding to three body types was obtained using the 3D scanning data and the cross-section convex hull, and compared with existing garment block and evaluated fitness of the blocks.FindingsIn total, 11 main components used to characterize the 3D morphological features of young women were obtained, which could explain 95.28 percent features of young women’s upper body. By cluster analysis, the body shape of women was divided into three categories. The block of three body types was obtained by the construction of the convex hull model.Originality/valueThis paper investigates a classification method of the body shape based on space vector length, which can effectively reflect the difference of surface shape of human body and further improve the matching degree of human body and clothing.

Authors: Khin Sabai , Ho Theresa CF 
Published: December 2018

PurposeDespite the growing importance of digital innovation conceptualized as innovative digital solutions that enable digital transformation of businesses across industries, empirical study of factors related to digital innovation is still scant, creating a knowledge gap. To fill this gap, this paper aims to examine the effect of digital orientation and digital capability on digital innovation, and also the mediating effect of digital innovation on the link between organizational performance and digital orientation as well as digital capability.Design/methodology/approachThis study tests a new conceptual framework using a survey data of 105 small to medium-sized IT firms in Malaysia and employing structural equation model (SEM) analysis from partial least square (PLS) approach.FindingsThe results show that digital orientation and digital capability have positive effect on digital innovation and also that digital innovation mediates the effect of technology orientation and digital capability on financial and non-financial performance.Practical implicationsThe findings encourage the firms to take the opportunity of emerging digital technologies and digitalization trend in industries by being committed toward embracing new digital technologies and upgrading their digital capabilities to become innovation leaders and also to boost firms’ performance.Originality/valueThis study is one of the first studies that explain how emerging digital technologies can be leveraged to create innovative digital products and services and subsequently boost their business performance. It also fills the literature gaps related to driving factors of digital innovation and mediating role of digital innovation on the link between its driving factors and performance.
Values statements
Authors: Allison Jerry 
Published: December 2018

PurposeThis paper aims to examine 611 values statements to determine if values statements contain characteristics of organizational culture as provided by Denison and Mishra (1995). The general hypothesis given is there is a relationship between values statements and culture characteristics. Four testable hypotheses, one for each of Denison and Mishra’s (1995) characteristics, are created and tested.Design/methodology/approachThe process in testing the hypotheses had two components. First, a taxonomy of the values statements had to be determined. This involved using natural language characteristics rather than predetermined classes to create a taxonomy based on the language itself. Second, a custom dictionary for each characteristic had to be created based on Neuendorf (2017) to perform content analysis. Once the values statements were coded with a taxonomic classification and with culture characteristics, a Chi-Square test was performed to determine a relationship between the statement type and the cultural characteristic, and then a multinomial regression test was performed to determine strength and direction of the relationships.FindingsThe tests for all four hypotheses produced significant results in the Chi-Square test. The multinomial regression tests showed primarily that Business statements types often lack adaptability and stakeholder involvement cultural elements. Additionally, Religion statement types are positively related to adaptability and mission.Research limitations/implicationsThis paper creates a taxonomy and supplies the rules for classification. Values statements can now be classified using those rules and the classification used in analysis. Additionally, as values statements span over organizational culture, strategic management and strategic communication, these statements become a focal point for studying multiple topics across these fields. More particularly, finding the negative relationship between the Adaptability characteristic with the Business statement type and the involvement characteristic with the Business statement type may provide a cultural explanation for many mixed result studies on organizational success.Practical implicationsOrganizational culture can be displayed by way of values statements and can potentially affect organizational strategy and organizational communication. Wording is extremely important in creating a values statement, and that statement must clearly reflect the cultural values of the organization.Originality/valueFirst, this paper creates a taxonomy of values statements that is far more complete than anything created before. Second, by examining language, this paper discovers a link between organizational culture, strategic management and strategic communication.

Authors: Serrano Rosiane , Lacerda Daniel Pacheco , Cassel Ricardo Augusto , Soares Priscila Ferraz , Piran Fabio Sartori 
Published: December 2018

Purpose
Football is significant in the global economic context. However, the same significance is not identified in the value added to the chain, as the elements that make it up act in a disintegrated and independent manner with undesired effects. Consequently, it is necessary to structure the undesired effects to seek the basic causes that sustain this problematic situation. Thus, this paper aims to use a CRT to structure the undesired effects and basic causes that limit the positive economic impacts of the south Brazilian football value chain.

Design/methodology/approach
A semi-structured questionnaire was applied with questions about the existing constraints. Based on the answers in the interviews, the current reality tree was elaborated, premised on identifying the basic causes that sustain the undesirable effects detected.

Findings
Among the main results, it was identified that management problems of the traditional leaders of football clubs and federations are considered the main reason why south of Brazil football cannot fully exploit its economic potential.

Originality/value
It is evidenced that the paper shows the undesired effect that has the most impact on the development of this chain, and it is important to propose improvements to its root causes, aiming at greater efficacy of the resulting actions.

Authors: Qiu Bingjing , Zhao Jiyun , Man Jiaxiang 
Published: December 2018

Purpose
Aiming at improving the mechanical efficiency, the applicability and the working life of high water-based hydraulic motor (HWBHM) under working conditions at low speed and high pressure, the friction performance of different matching materials for piston slipper – crankshaft pair with high water-based hydraulic fluid (HWBHF) under working conditions at low speed and high pressure – were studied.

Design/methodology/approach
The friction experiments for different materials (316L, 316L with surface coating OVINO – tetrahedral amorphous carbon [TAC; 316L-TAC] – 316L with surface coating OVINO-graphite intercalated compound [GIC; 316L-GIC] and polyetheretherketone [PEEK] reinforced with 30 per cent carbon fiber [PEEK-30CF]) under HWBHF lubrication were implemented on a pin-disk friction abrasion machine to determine the variations of coefficient of friction (CoF) and wear rate for each matching materials. In addition, the roughness and the morphology of worn surface of different matching materials were quantitatively characterized.

Findings
The study revealed that material combinations have different friction performances. Test results showed that the abrasion of matching type stainless steel (SS) and SS is rather serious, and the method of surface coating could improve the friction performance of SS when friction with other materials. For matching type of SS with surface treatment (SS-ST) and SS-ST, 316L-GIC and 316L-GIC have relatively stable CoF, and the wear rate was smaller than other matching materials, while 316L-TAC and 316L-TAC has the smaller CoF than that of 316L-GIC. Matching materials 316L-GIC with PEEK-30CF of matching type SS-ST and PEEK-30CF has more stable COF and better wear resistance than those of other matching materials.

Originality/value
This research has laid a foundation for the improvement of service life and working efficiency of friction pair in HWBHM under working conditions at low speed and high pressure.

This paper aims to investigate the experimental technique for large diameter bearings.

Design/methodology/approach
To obtain the experimental support for rotor-bearing system design, an experiment focusing on vibration monitoring is given. The sensors arrangement, monitoring system and critical speed identification method are provided.

Findings
By using test bench in factory unit, a large amount of vibrations data of different working situations is obtained. In addition, a method named non-excitation identification for critical speed is proposed. The critical speed of rotor identified through vibration data is given. The theoretical calculation results are also presented.

Originality/value
The basis for rotor-bearing system design can be obtained through comparisons between the experimental results and the theoretical calculation data.
Effect of form errors on oil film characteristics of hydrodynamic journal bearings based on small displacement torsor theory
Authors: Ma Xun , Xu Wubin , Zhang Xueping , Yang Fuyong 
Published: December 2018

Purpose
This paper aims to investigate how form error of journal affects oil film characteristics, which are composed of several parameters including the maximum film pressure, film moment, frictional coefficient and carrying-load capacity.

Design/methodology/approach
A new generalized equation based on the small displacement torsor theory is derived, as well as its capability of representing types of form error on the journal, using four specified parameters in a three-dimensional (3D) state. Based on the new generalized equation of form errors, the Reynolds equation is represented and solved numerically using the Swift–Stieber boundary condition.

Findings
The results show that the form errors of journal have significant influence on all oil film characteristics. However, the film moment remains nearly unchanged as film characteristics, especially eccentricity ratio, become large. All film characteristics investigated vary periodically as the form error. More importantly, it is found that the film pressure distribution transforms to an asymmetric shape along the axial direction of the bearing, no longer a symmetric shape in the case of two-dimensional (2D) form errors. It is necessary to substitute the 3D form error model, which takes the variations of the film characteristics in axial direction into account, for the 2D model in the designing stage of journal bearings.

Originality/value
First, the effect of the form error of the journal on the performance of hydrodynamic journal bearings is studied in the view of the film characteristics systematically. Secondly, the new generalized equation of form error, derived by SDT theory, is capable of representing any types of form error on the journal, not only representing one type of form error merely.
