State-of-practice for risk-based quality assurance in state departments of transportation
Authors: Oechler Erick , Molenaar Keith R. , Hallowell Matthew , Scott Sidney
Published: August 2018

Purpose

Selecting an optimal quality assurance (QA) process can have significant implications on the long-term durability and lifecycle costs of transportation projects. Currently, the approaches used by state departments of transportation (DOTs) to optimize QA are undocumented and the impact of project-specific factors are unknown. The paper aims to discuss these issues.

Design/methodology/approach

State-of-practice was documented via a review of DOT guidance documents, standard specifications and minimum sampling and testing requirements; a survey of 58 state DOT representatives; and interviews with eight DOTs.

Findings

DOT approaches to QA management are very diverse but can be organized into five levels that range from ad hoc visual inspection of materials to DOT-managed sampling and testing. Project size, location and complexity have strong influence on the selection of a QA approach, but DOT demographics and project delivery method are less significant.

Practical implications

Present approaches to the selection of a QA approach are generally informal, subjective and do not involve formal risk analyses. A data-driven approach for transportation projects is clearly needed.

Originality/value

Understanding how state DOTs approach QA method selection will serve as a foundation for new methods of QA optimization.
Behavioural response patterns: an investigation of the early stages of major incidents
Authors: Hanna Sawalha Ihab
Published: August 2018

Purpose

This paper aims to investigate the different patterns of organizational behavioural responses to major incidents and develop an original classification of these patterns.

Design/methodology/approach

An extensive literature review was made to investigate the different patterns of behavioural responses to major incidents and then to develop an original classification of these patterns. Several sources of information, such as case studies, technical reports, academic journal articles and organizational internal reports were used.

Findings

Organizations respond differently to major incidents. This was clear from the different behavioural patterns investigated and identified. Behavioural patterns determine levels of resilience and ability of organizations to overcome and ultimately survive major incidents.

Practical implications

To promote effective and organized behavioural response patterns to major incidents and improve consistency of responses across the organization, relevant authorities should demonstrate to all private and public enterprises the significance of effective behavioural responses, thus enabling them to better respond to various potential emergencies.

Originality/value

A number of models of human behaviour have been introduced in the literature to understand how people respond to emergency situations. They each take a different perspective on human behaviour but no single theory has emerged as the leading paradigm. This highlights the complexity of understanding human behaviour in such situations and the need for a better classification of behavioural patterns. To the author’s knowledge, this is one of very few studies to investigate, identify and categorize behavioural response patterns to major incidents. This research is expected to be of a substantial value for those interested in improving organizational behaviour during major incidents, as well as those interested in improving organizational resilience.

Repercussions of precarious employment on migrants’ perceptions of healthcare in Greece
Authors: Fouskas Theodoros
Published: August 2018

Purpose

The purpose of this paper is to investigate the cases of Bangladeshi, Filipina, Nigerian, Palestinian and Pakistani migrant workers and how the frame of their work and employment in precarious, low-status/low-wage jobs affects their perceptions and practices regarding health and access to healthcare services.

Design/methodology/approach

Using qualitative research methodology, the analysis via in-depth interviews focuses on male Bangladeshi, Nigerian, Pakistani and Palestinian unskilled manual and textile laborers as well as street vendors, and female Filipina live-in domestic workers.

Findings

Migrants are entrapped in a context of isolative and exploitative working conditions, i.e., in unskilled labor, textile work, street-vending, personal services, care and domestic work, which lead them to adopt a self-perception in which healthcare and social protection are not a priority.

Social implications

Throughout the paper it has become clear that these precarious low-status/low-wage jobs have an important underside effect on migrants’ lives, intensifying labor and health instability and exposing migrants to employment-generating activities that do not guarantee health safety. In Greek society, the impact of migration on public health is characterized by many as a “time bomb ready to explode,” especially in urban centers. Meanwhile, the economy and particularly the informal sector of the labor market is benefiting from migrant workers. More research is needed as this mode of exploitative labor and precarious employment needs to be adequately addressed to mitigate barriers in the access of labor and healthcare rights.

Originality/value

Via its contribution to the sociology of migration with particular emphasis on labor healthcare, the paper provides evidence that due to their concentration in precarious, low-status/low-wage jobs migrant workers have very limited access to healthcare services. The removal of inequalities and discrimination against migrant workers in accessing healthcare services and medical care is a challenge for South European Union countries and particularly for Greece. However, in spite of this, there is no uniform policy in the management of migrants with respect to their access to health services. The paper will aid debates between policy makers and academics working on migration and inequalities due to the division of labor and health disparities, will contribute to the understanding of the perils attached to precarious, low-status/low-wage jobs and in addressing health inequalities effectively.
The flexibility of industrial additive manufacturing systems
Authors: Eyers Daniel R. , Potter Andrew T. , Gosling Jonathan , Naim Mohamed M.
Published: August 2018

Purpose

Flexibility is a fundamental performance objective for manufacturing operations, allowing them to respond to changing requirements in uncertain and competitive global markets. Additive manufacturing machines are often described as “flexible,” but there is no detailed understanding of such flexibility in an operations management context. The purpose of this paper is to examine flexibility from a manufacturing systems perspective, demonstrating the different competencies that can be achieved and the factors that can inhibit these in commercial practice.

Design/methodology/approach

This study extends existing flexibility theory in the context of an industrial additive manufacturing system through an investigation of 12 case studies, covering a range of sectors, product volumes, and technologies. Drawing upon multiple sources, this research takes a manufacturing systems perspective that recognizes the multitude of different resources that, together with individual industrial additive manufacturing machines, contribute to the satisfaction of demand.

Findings

The results show that the manufacturing system can achieve seven distinct internal flexibility competencies. This ability was shown to enable six out of seven external flexibility capabilities identified in the literature. Through a categorical assessment the extent to which each competency can be achieved is identified, supported by a detailed explanation of the enablers and inhibitors of flexibility for industrial additive manufacturing systems.

Originality/value

Additive manufacturing is widely expected to make an important contribution to future manufacturing, yet relevant management research is scant and the flexibility term is often ambiguously used. This research contributes the first detailed examination of flexibility for industrial additive manufacturing systems.
Investigation of wear mechanism of forged steel piston skirt under boundary lubricated conditions
Authors: Jian Zhang , Lijun Deng , Guannan Hao , Shiying Liu
Published: August 2018

Purpose

With the implementation of new emission standards, the thermal–mechanical coupling load of engine pistons becomes more important. In this case, forged steel material with higher fatigue limit and impact resistance has been applied gradually in piston manufacturing. However, new failure problems emerge, and the wear of skirt under boundary lubrication conditions is an essential problem which needs to be solved urgently.

Design/methodology/approach

In this research, the abrasion testing machine was used to simulate the wear behavior under different conditions of normal pressure, relative velocity and surface roughness. Besides, the wear morphology was observed by scanning electron microscope. Then, the wear model was established by using test results fitting method, offering a way to conduct qualitative analysis for the wear problem under the same conditions.

Findings

The results show that mainly the wear mechanism of the piston skirt under boundary lubricated conditions is adhesive wear and abrasive wear. In addition, the coefficient and wear rate will increase with the increase in the normal load and surface roughness and decrease with the increase in the relative speed. In the wear model, the wear loss is mainly influenced by the normal load, the relative sliding speed and the wear time.

Originality/value

The wear degree of piston skirt was qualitatively obtained in this investigation by factors such as pressure, velocity and so on, and the wear mechanism of forged steel piston skirt under boundary lubrication conditions was also determined. These could provide theoretical support for further optimization of cylinder motion and oil supply system, reduction of friction loss and power loss.
Online infrared spectra detection of lubricating oil during friction process at high temperature
Authors: Jin Yongliang , Duan Haitao , Wei Lei , Chen Song , Qian Xuzheng , Jia Dan , Li Jian
Published: August 2018

Purpose

This paper aims to investigate the tribological behavior and online infrared spectra of three types of lubricating oils containing dinonyl diphenylamine (DNDA) antioxidant, which are mineral oil (MO), poly alpha olefin (PAO) and trimethylolpropane trioleate (TMPTO), during the friction process at high temperature (temperature rising at first and isothermal holding afterwards).

Design/methodology/approach

A platform of low speed four-ball tribometer equipped with a temperature controller combined with infrared spectrometer was established. MO, PAO and TMPTO base oils were mixed with 1.0 Wt.% DNDA antioxidant, coded as MOa, PAOa and TMPTOa in sequence. The friction coefficient and online infrared spectra of the oils were tested during the friction process of temperature rising at first and isothermal holding afterwards, and the wear tracks of the upper balls were measured using a confocal scanning optical microscope.

Findings

The results indicated that the DNDA antioxidant was depleted to reduce the generation of alcohols and carbonyl products, and the depletion rate of DNDA followed the sequence of MOa > PAOa > TMPTOa. In the temperature rising friction process, the critical transition of friction coefficient was confirmed. The addition of DNDA antioxidant reduced the temperature of the oils at the critical transition of friction coefficient, and the temperature followed the sequence of TMPTOa > PAOa > MOa. After the critical transition, the friction coefficient was first increased and then declined to a steady value; the friction coefficient of MOa increased and declined first, followed by PAOa and TMPTOa. In the steady stage of friction, there was no obvious effect of DNDA on the friction coefficient of the oils. Moreover, DNDA enhanced the wear properties of MOa and PAOa; no obvious improvement was revealed for the wear property of TMPTOa.

Originality/value

The established platform of low speed four-ball tribometer combined with infrared spectrometer successfully realized online testing of the structure changes of lubricating oil during high temperature friction, which can give some reference on the oxidation and friction researches of lubricating oil.
In-situ capacitive sensor for monitoring debris of lubricant oil
Authors: Wang Yishou , Han Zhibin , Gao Tian , Qing Xinlin
Published: August 2018

Purpose

The purpose of this study is to develop a cylindrical capacitive sensor that has the advantages of high resolution, small size and designability and can be easily installed on lubricant pipeline to monitor lubricant oil debris.

Design/methodology/approach

A theoretical model of the cylindrical capacitive sensor is presented to analyze several parameters’ effectiveness on the performance of sensor. Numerical simulations are then conducted to determine the optimal parameters for preliminary experiments. Experiments are finally carried out to demonstrate the detectability of developed capacitive sensors.

Findings

It is clear from experimental results that the developed capacitive sensor can monitor the debris in lubricant oil well, and the capacitance values increase almost linearly when the number and size of debris increase.

Research limitations/implications

There is lot of further work to do to apply the presented method into the application. Especially, it is necessary to consider several factors’ influence on monitoring results. These factors include the flow rate of the lubricant oil, the temperature, the debris distribution and the vibration. Moreover, future work should consider the influence of the oil degradation to the capacitance change and other contaminations (e.g. water and dust).

Practical implications

This work conducts a feasibility study on application of capacitive sensing principle for detecting debris in aero engine lubricant oil.

Originality/value

The novelty of the presented capacitance sensor can be summarized into two aspects. One is that the sensor structure is simple and characterized by two coaxial cylinders as electrodes, while conventional capacitive sensors are composed of two parallel plates as electrodes. The other is that sensing mechanism and physical model of the presented sensor is verified and validated by the simulation and experiment.
Tribocorrosion and the surface repassivation behavior of Monel 400 alloy in artificial seawater
Authors: Ma Fuliang , Zeng Zhixiang , Gao Yimin
Published: August 2018

Purpose

This paper aims to study the tribocorrosion and the surface repassivation behaviors of Monel 400 alloy in artificial seawater.

Design/methodology/approach

In this study, the tribocorrosion behavior of Monel 400 alloy was studied under different applied loads in artificial seawater by using a pin-on-disk tribometer equipped with an electrochemical workstation. The applied loads were selected ranging from 50 to 200 N. The surface repassivation behavior of Monel 400 alloy was studied by X-ray photoelectron spectroscopy.

Findings

It was demonstrated that mass loss was determined by the combined effect of mechanical wear and chemical corrosion. The surface repassivation mechanism of the alloy is that layer corrosion product film formed on the surface of Monel 400 alloy, which can protect metal matrix from future corrosion.

Originality/value

This research adds original content in revealing the tribocorrosion and surface repassivation behaviors of Monel 400 alloy under different loads, which offer a theoretical basis for the application under the corrosion and wear environment of Monel 400.
Measurement and calculation of oil film thickness in a ball bearing
Authors: Wen Baogang , Ren Hongjun , Dang Pengfei , Hao Xu , Han Qingkai
Published: August 2018

Purpose

The oil film thickness provides a key performance indicator of a ball bearing lubrication condition. This paper aims to propose an approach to calculate and measure the oil film thickness of the bearing.

Design/methodology/approach

On a specially designed test rig, measurement of the capacitance is used to monitor the oil film thickness of ball bearing. A corrected film thickness formula taking account of the influences of non-Newtonian shear thinning and thermal is introduced to predict the oil film thickness of ball bearing. And then the film thickness distribution and the corresponding capacitances are calculated.

Findings

Measurement and calculation of oil film thickness in a ball bearing are carried out under various rotating speeds and external loads. By comparing the calculated capacitances with measured results, it can be concluded that the calculated results obtained by the amended film thickness formula are much closer to the test findings than the classical computed values according to Hamrock–Dowson.

Originality/value

A new corrected film thickness formula is introduced in predicting oil film thickness of ball bearing and verified by the series of experiments according to capacitance method.
Managing supply chain risks and delays in construction project
Authors: Panova Yulia , Hilletofth Per
Published: August 2018

Purpose

The purpose of this paper is to investigate models and methods for managing supply chain risks and delays in construction projects.

Design/methodology/approach

The study mainly employs quantitative analysis in order to identify disruptions in construction supply chains. It also uses paradigms of simulation modeling, which are suitable for risk assessment and management. Both qualitative and quantitative data were collected through a literature review and details of specific construction projects, respectively. A dynamic modeling method was used, and the model was provided with an event-based simulation. Simulation modeling was used to measure the performance of the system.

Findings

The study shows the benefits of applying the dynamic modeling method to a construction project. Using event-based simulation, it was found that construction delays influence both the magnitude and the probability of disruption. This method contributes to the existing theoretical foundations of risk management practices, since it also considers the time factor. This method supplements the Monte Carlo statistical simulation method, which has no time representation. Using empirical analysis, the study proposes increasing the safety stock of construction materials at the distribution center, so as to mitigate risks in the construction supply chain.

Research limitations/implications

The research considers a single case of a hypothetical construction project. The simulation models represent a simple supply chain with only one supplier. The calculations are based on the current economic scenario, which will of course change over time.

Practical implications

The outcomes of the study show that the introduction of a safety stock of construction materials at the distribution center can prevent supply chain disruption. Since the consideration of risks at all stages of construction supply chain is essential to investors, entrepreneurs and regulatory bodies, the adoption of new approaches for their management during strategic planning of the investment projects is essential.

Originality/value

This dynamic modeling method is used in combination with the Monte Carlo simulation, thus, providing an explicit cause-and-effect dependency over time, as well as a distributed value of outcomes.
FDI, service intensity, and international marketing agility
Authors: Li Ruiqin , Liu Yipeng , Bustinza Oscar F.
Published: August 2018

Purpose

The purpose of this paper is to provide a nuanced understanding of international marketing agility by connecting organizational capability literature with that of standardization and adaptation. The focus of the research is to clarify whether managing the tension between product standardization and service customization generates an extra premium in international markets.

Design/methodology/approach

Two disaggregated Chinese data sets, the Annual Survey of Industrial Enterprises and the China Customs Database, are used for developing an econometric model. Export quality improvement is the outcome variable in reflecting the effect of international marketing agility on performance.

Findings

International marketing agility is reached through upstream FDI intensity, particularly in the context of service FDI. Manufacturing sectors with higher service intensity have more agility, being more likely to generate export quality.

Research limitations/implications

This study makes three theoretical contributions by clarifying the concept of international marketing agility as an organizational capability generated by manufacturing standardization and service customization; investigating the influence of upstream FDI intensity for export quality while taking into account the industry contexts; and obtaining an enhanced understanding of the service intensity of manufacturing firms on export quality.

Originality/value

The authors offer a nuanced and contextualized understanding of international marketing agility and explore the complex relationships between FDI, service intensity and export quality.
SMED methodology based on fuzzy Taguchi method
Authors: Ekincioğlu Caner , Boran Semra
Published: August 2018

Purpose

There can be activities that cannot reduce times by conventional single minute exchange of die (SMED) tools. In this case more advanced tools are needed. The purpose of this paper is to integrate the fuzzy Taguchi method into the SMED method in order to improve the setup time. The reason for using fuzzy logic is the subjective evaluation of factor’s levels assessment by experts. Subjective assessment contains a certain degree of uncertainty and is vagueness. The fuzzy Taguchi method provides to determining optimal setup time parameters in an activity of SMED. So it is possible to reduce time more than the conventional SMED method.

Design/methodology/approach

In this study, the SMED method and the fuzzy Taguchi method are used.

Findings

In this study, it has been shown that the setup time is reduced (from 196 to 75 min) and the optimum value can be given at the intermediate value by the fuzzy Taguchi method.

Originality/value

In this limited literature research, the authors have not found a study using the fuzzy Taguchi method in the SMED method.
The impact of strategy on public sector set-aside programs: the case of the state of Ohio
Authors: Blount Ian Y. , Seetharaman Jay , Brown Trevor L.
Published: August 2018

Purpose

The purpose of this study is to examine the impact of program strategy on the implementation of the efficacy of a procurement set-aside program at the state level.

Design/methodology/approach

This study examines the impact of program implementation strategy across two administrations considering the most compelling alternative arguments for what drives agency purchasing through contracts with MBEs.

Findings

The results of mixed effects linear regression models on the procurement expenditures of 70 state agencies in Ohio from 2008-2015 show significantly higher rates of procurement expenditures with MBEs under the Kasich administration.

Originality/value

These results provide support for the argument that changes in program implementation strategy led to substantive increases in the use of MBEs by state agencies in Ohio.
Intercultural competence and customer facial recognition
Authors: Henderson Geraldine Rosa , Rank-Christman Tracy , White Tiffany Barnett , Grantham Kimberly Dillon , Ostrom Amy L. , Lynch John G.
Published: August 2018

Purpose

Intercultural competence has been found to be increasingly important. The purpose of this paper is to understand how intercultural competence impacts service providers’ ability to recognition faces of both black and white consumers.

Design/methodology/approach

Two experiments were administered to understand how intercultural competence impacts recognition of black and white consumer faces.

Findings

The authors find that the more intercultural competence that respondents report with blacks, the better they are at distinguishing between black regular customers and black new shoppers in an experiment. The authors find no impact of intercultural competence on the ability of respondents to differentiate between white consumers. These findings hold for respondents in the USA and South Africa.

Research limitations/implications

One limitation of this research is that the studies were conducted in a controlled lab setting. Thus, one could imagine additional noise from a true consumer setting might increase the effects of these results. Another limitation is the focus on only black and white consumer faces. In this paper, the authors focused on these two races, specifically to keep the factorial design as simplified as possible.

Originality/value

The implications of this research are important given that the ability of employees’ recognizing customer faces can affect customers’ day-to-day interactions in the marketplace.
Corporate social responsibility and employees’ affective commitment
Authors: Bouraoui Khadija , Bensemmane Sonia , Ohana Marc , Russo Marcello
Published: August 2018

Purpose

The purpose of this paper is to examine the relationship between corporate social responsibility (CSR) and employees’ affective commitment. Three underlying mechanisms are used to explain the relationship between CSR and commitment, namely, deontic justice, social identity theory and social exchange theory.

Design/methodology/approach

Data were collected through survey questionnaires. The sample consisted of 161 employees who work in private and public organizations in Tunisia. Regression analysis was conducted using a multiple mediation model.

Findings

The results reveal a positive and significant relationship between CSR and employees’ affective commitment. The perception of person–organization fit, organizational identification and perceived organizational support mediates the relationship between CSR and affective commitment.

Originality/value

With regard to CSR, past studies have never deal with deontic values in analyzing work behaviors. Furthermore, most previous studies have considered a direct effect between CSR perceptions and affective commitment. This study extends the literature by conceptualizing the indirect mechanisms linking CSR to employees’ affective commitment.
Internationalisation in higher education –an internationalist perspective
Authors: Byram Michael
Published: August 2018

Purpose

This paper aims to argue for the significance of internationalism for the internationalisation of higher education. It analyses some conceptualisations and definitions of internationalisation before explaining the concept of internationalism, and variations of it, to demonstrate that internationalism has a moral dimension which could, and the author argues, provide a normative value base for the processes of internationalisation.

Design/methodology/approach

This paper is a cross-disciplinary, conceptual exploration.

Findings

The argument concludes with a listing of principles which should give a moral direction to internationalisation.

Research limitations/implications

The approach proposed is the basis for evaluations of different aspects of internationalisation such as the design and implementation of curricula.

Practical implications

The approach taken here, if implemented, would lead to changes in curricula and processes of internationalisation.

Social implications

The impact of internationalisation, and particularly of student mobility as an aspect of it, is already significant, and the perspective presented here would lead to more coherent interactions in mobility situations.

Originality/value

Using the neglected concept of internationalism brings a new perspective and challenge to internationalisation.
Synthesis, antioxidant and antibacterial activity of azo dye-stilbene hybrid compounds
Authors: Rezaei-Seresht Esmail , Salimi Aboulfazl , Mahdavi Behnam
Published: August 2018

Purpose

The purpose of this paper is synthesis and evaluation of antioxidant and antibacterial activities of a series of new azo dyes derived from 4-aminostilbene.

Design/methodology/approach

First, the starting material 4-aminostilbene was prepared via two successive Wittig and reduction reactions from 4-nitrobenzyl bromide. The obtained 4-aminostilbene was then reacted with some phenols under the normal azo coupling reaction conditions to give five new azo products. Antioxidant activity of the azo compounds was determined by radical scavenging assay using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical. Also, the antimicrobial activity of the compounds against one gram-positive and eight gram-negative strains was evaluated based on the inhibition zone using disc diffusion assay.

Findings

The structures of the azo dyes were identified and characterized by fourier-transform Infrared, 1H nuclear magnetic resonance (NMR) and ultraviolet-visible (UV-V) is spectroscopic methods. All the compounds showed higher antioxidant activity than ascorbic acid (Asc) and butylated hydroxytoluene (BHT) as positive controls. Moreover, the compounds showed lower antibacterial activity than the standard antibiotic vancomycin.

Research limitations/implications

Excellent antioxidant activity, along with antibacterial activity against Streptococcus pneumoniae and Pseudomonas aeruginosa, was observed for the two synthesized azo dyes.

Originality/value

Five novel azo dyes based on 4-aminostilbene were synthesized. The dyes have a highly p-extended conjugated structure comprising the phenolic and stilbenic segments, and they indicated good antioxidant activity, so that the two dyes (2c and 2d) even showed much more scavenging activity compared to BHT which is used as an antioxidant agent in food industries. These compounds with highest antioxidant activity also inhibited the growth of S. pneumoniae and P. aeruginosa.

Authors: Salehi Mahdi , Majbouri Yazdi Hoda , Nekoei Mohammad
Published: August 2018

Purpose

Human developments in constructing buildings and their subsequent infrastructures despite certain advantages have unfortunately considerable effects on the environment, such that construction could be named as the main exploiter of the natural, physical and biologic resources. Hence, the purpose of this paper is to evaluate the effect of communication capabilities of the suppliers and external green integration on the green performance and financial performance of engineering and construction companies.

Design/methodology/approach

The statistical population of the study comprises all 300 members of the Building Engineering System of South Khorasan Province. According to the Morgan table (1972), 167 participants were selected as the sample of the study using the stratified random sampling, and a standard questionnaire was distributed among them. Data were collected through library and filed methods. Data were analyzed using the factor analysis method (SPSS), and LISREL Software was used for evaluating the research hypotheses.

Findings

The obtained results indicated that information sharing has a significant effect on environmental coordination and the green balance of green cost reduction of coordinate competitive advantage.

Originality/value

Accordingly, given the results obtained from a developmental-practical research, the authors initially gathered and classified the required data on the construction industry using the library and field methods, then extracted the obstacles of the supply chain to help facilitate the implementation of efficiency in the so-called industry.
Football clubs as mediators in sponsor-stakeholder relations
Authors: Junghagen Sven
Published: August 2018

Purpose

Far from all, football clubs can provide the same level of exposure effects as global football brands, even on local level, and many of these clubs also operate in a context of commercial immaturity. The purpose of this paper is to show what value a football club can provide for sponsors in a context of commercial immaturity with limited expected exposure effects.

Design/methodology/approach

The study is based on a case study approach, taking its point of departure in two sponsor brand management paradigms, the projective and relational paradigm. The case of Malmö FF in the Swedish top tier league and the club’s official partners has been chosen to exemplify the commercially immature context.

Findings

The study has shown that the most important value the club can provide for sponsors is to act as a mediator in sponsor–stakeholder relations. Exposure effects are subordinate to the relational effects sponsors achieve through their sponsorship.

Research limitations/implications

The study indicates that the relational construct in the sponsorship literature should to a greater extent include sponsor–stakeholder relations, beyond the sponsor–club dyad, in a context of commercial immaturity.

Practical implications

The results indicate that club management should engage in stakeholder management with a strong focus on stakeholders of sponsors to provide value for these sponsors.

Originality/value

This study explores a new dimension to the relational construct of sponsorship, using the relational paradigm of brand management in a context of commercial immaturity. The mediating effect of the club is a contribution to the discourse on the relational construct.
The influence of the nature of children's disabilities on societal reactions experienced by their parents
Authors: Broomhead Karen E.
Published: August 2018

This paper details a qualitative study which examined the influence of the nature of children's disabilities on stigmatisation experienced by their parents. To explore stigmatisation, semi‐structured interviews were conducted with 22 parents of children with a range of disabilities. Findings highlighted that differential treatment was experienced by all parents, regardless of the nature of their children's disabilities. However, the types of reactions from others were influenced by three key factors; visibility of the child's disability, evidence of behaviour deemed to be socially inappropriate, and perceived controllability of the disability. Parents of children with behavioural, emotional and social difficulties experienced intensely negative reactions from others, whilst other parents experienced much pity. The implications of these findings for policy and practice are considered, indicating that parents may be encountering stigma solely based on the nature of their children's disabilities. The paper concludes by stressing the importance of support outlets for parents.
Orthostatic intolerance in enhanced recovery laparoscopic colorectal resection
Authors: Eriksen Jens R. , Munk‐Madsen Pia , Kehlet Henrik , Gögenur Ismail
Published: August 2018

Background

Orthostatic hypotension (OH) and intolerance (OI) are common findings in the early postoperative period after major surgery and may delay early mobilization. The mechanism of impaired orthostatic competence and OI symptoms is not fully understood, and specific data after colorectal surgery with well‐defined perioperative care regimens and mobilization protocols are lacking. The aim of this study was to investigate the prevalence, possible risk factors and the impact of OI in patients undergoing elective minimal invasive colorectal cancer resection.

Methods

A prospective single‐centre study with an optimal enhanced recovery program and multimodal analgesic treatment. OI and OH were evaluated using a well‐defined mobilization protocol preoperatively and 6 hour and 24 hour postoperatively.

Results

A total of 100 patients were included in the data analysis. The overall median length of stay was 3 days (1‐38). OI was observed in 53% of the patients 6 hour postoperatively and in 24% at 24 hour. OI at 6 hour postoperatively was associated with younger age, lower BMI, and female gender. At 24 hour postoperatively, female gender and ASA class >1 was associated with OI. Opioid consumption and intravenous fluid during the first 24 hour was not associated with OI. Postoperative complications were equally observed between patients with and without OI. Although not statistically significant, patients with OI at 24 hour postoperatively had prolonged LOS (mean 4.0 vs 7.5 days, P = 0.069) compared with patients without OI.

Conclusion

Postoperative orthostatic intolerance is a common problem during the first 24 hour following laparoscopic colorectal resection and may be followed by delayed recovery.
Developing a Community of Practice: Michael Gaffikin and Critical Accounting Research
Authors: Cortese Corinne , Wright Claire
Published: August 2018

This paper demonstrates the role of a community of practice in academic endeavour, focusing on the influence of place and the role of thought leaders in guiding academic development. This is illustrated with reference to the influence of Emeritus Professor Michael Gaffikin in establishing a critical accounting community of practice at the University of Wollongong (UOW) through his PhD supervisions. Social network analysis (SNA) is used to visualize the 43 PhD supervisions undertaken by Gaffikin during his career, and subsequent PhD supervisions of his students, and students of those students. SNA illustrates the structure of relationships, and the paths through which scholars learnt from one another, which we combine with qualitative analysis of recollections, acknowledgments, and doctoral theses. We demonstrate the role of Gaffikin, as the intellectual thought leader, and UOW, as the intellectual place, in the development of the critical accounting community of practice. The development of critical accounting scholarship was a function of Gaffikin's intellectual and professional leadership, which he executed through PhD supervision, the annual Doctoral Consortium, and his direction at UOW. This paper highlights the importance of local communities for the development of research agendas, and the influence of PhD supervisors on the professional development of students.

Three‐dimensional laparoscopy‐assisted bowel resection for cavernous hemangioma of the rectum: Report of two cases
Authors: Fu Zheng‐wei , Wang Li‐xia , Zhang Zhen‐yu , Luo Qi‐feng , Ge Hai‐yan
Published: August 2018

The safety and feasibility of 3‐D laparoscopy‐assisted bowel resection were demonstrated in the management of rectal cancer. However, this procedure’s role in the management of patients with diffuse cavernous hemangioma of the rectum has not been evaluated. Here, two patients were diagnosed with diffuse cavernous hemangioma of the rectum by colonoscopy and abdominal imaging. One case underwent pull‐through transection and coloanal anastomosis in 3‐D laparoscopy‐assisted surgery. In another patient, 3‐D laparoscopy‐assisted abdominoperineal resection was performed. The operations were safely performed in both cases. The two patients recovered uneventfully, and satisfactory postoperative outcomes were demonstrated. This report shows that 3‐D laparoscopy‐assisted bowel resection may be safe and feasible for patients with diffuse cavernous hemangioma of the rectum.
On the Alternative Hypotheses for the Win Ratio
Authors: Mao Lu
Published: August 2018

We extend the results of Luo et al. (2015, Biometrics  71, 139–145) regarding the alternative hypotheses for the win ratio from hazard orders to the upper quadrant stochastic order on the plane. This extension substantially widens the range of alternatives against which the win ratio is known to be consistent. It incorporates alternatives induced by simple and popular copula models that are left out by the characterization of Luo et al. (2015). We also discuss how our results may be generalized to win ratios in multivariate and stratified settings.

Lymphoma incidence and survival in adolescent and young adult (AYA, defined as 15–39 years of age) and adult patients (>39 years) were assessed using Surveillance, Epidemiology, and End Results (SEER) data. From 2000 to 2014, 431 721 lymphoma cases were reported to SEER, 9% in AYA patients. In the AYA group, the highest age‐adjusted incidence rate was for classical Hodgkin lymphoma [HL; 3·4 per 100 000 person‐years; 95% confidence interval (CI), 3·38–3·49] followed by diffuse large B cell lymphoma (DLBCL; 1·56, 95% CI, 1·53–1·60) and for adults, it was plasma cell neoplasms (14·17, 95% CI, 14·07–14·27), DLBCL (13·86, 95% CI, 13·76–13·96) and chronic lymphocytic leukaemia (CLL; 13·19, 95% CI, 13·09–13·29). HL comprised 42% of lymphoma cases for AYAs, but only 4% in adults. The occurrence of DLBCL among AYAs and adults was similar, 18% and 20%, respectively. Twenty‐eight percent of AYAs compared with 9% of adults presented with stage II disease, and 21% of AYAs compared with 10% of adults had B‐symptoms. Extranodal disease was less common (33%) in AYAs than adults (59%). Overall, AYA patients with lymphoma have better 2‐ and 5‐year relative survival rates (RSRs) compared to adults. When restricted to HL and DLBCL, RSR of AYA patients exceeds adult RSR.
Autonomous Particles for Interactive Flow Visualization

Published: August 2018

We present an interactive approach to analyse flow fields using a new type of particle system, which is composed of autonomous particles exploring the flow. While particles provide a very intuitive way to visualize flows, it is a challenge to capture the important features with such systems. Particles tend to cluster in regions of low velocity and regions of interest are often sparsely populated. To overcome these disadvantages, we propose an automatic adaption of the particle density with respect to local importance measures. These measures are user defined and the systems sensitivity to them can be adjusted interactively. Together with the particle history, these measures define a probability for particles to multiply or die, respectively. There is no communication between the particles and no neighbourhood information has to be maintained. Thus, the particles can be handled in parallel and support a real‐time investigation of flow fields. To enhance the visualization, the particles' properties and selected field measures are also used to specify the systems rendering parameters, such as colour and size. We demonstrate the effectiveness of our approach on different simulated vector fields from technical and medical applications.
Gene network variation and alternative paths to convergent evolution in turtles

Diversification of the turtle's shell comprises remarkable phenotypic transformations. For instance, two divergent species convergently evolved shell‐closing systems with shoulder blade (scapula) segments that enable coordinated movements with the shell. We expected these unusual structures to originate via similar changes in underlying gene networks, as skeletal segment formation is an evolutionarily conserved developmental process. We tested this hypothesis by comparing transcriptomes of scapula tissue across three stages of embryonic development in three emydid turtles from natural populations. We found that alternative strategies for skeletal segmentation were associated with interspecific differences in gene co‐expression networks. Notably, mesenchyme homeobox 2 (MEOX2) and HOXA3‐5 were central hubs driving the activity of 2,806 genes in a candidate network for scapula segmentation, albeit in only one species. Even so, scapula muscle overgrowth corresponded to the activity of similar myogenic networks in both species. This and other derived developmental processes were not observed in the third species, which displayed the ancestral (unsegmented) scapula condition. Differential gene expression tests against this reference lineage supported histological and network analyses. Our findings illustrate that molecular underpinnings of convergent evolution, including during the diversification of the atypical turtle “body plan,” are influenced by variation in underlying developmental processes.

Aim

The telomere is a structure present at the ends of chromosomes, and is known to shorten with aging and successive rounds of cell division. However, very little is known about telomere attrition in post‐mitotic cells, such as neurons.

Methods

Using our originally developed quantitative fluorescence in situ hybridization method, we analyzed age‐dependent alterations of telomere length in three types of cells in the human cerebrum: neurons and glial cells in both the gray and white matter.

Results

In adults, telomeres were significantly longer in neurons than in glial cells, whereas in infants, telomere lengths did not differ among the three cell types. No aging‐related telomere attrition was evident in neurons. However, the telomeres of glial cells were shorter in older individuals than in younger individuals, and attrition was more rapid in the white matter than in the gray matter.

Conclusions

The present results suggest that the telomeres of neurons remain stable throughout life, whereas telomeres in white matter glial cells become significantly shorter with age. Examination of adults showed no significant correlation between telomere length and age in the three cell types. Although the present study was cross‐sectional, the results suggest that telomere shortening before adolescence contributes to the significant decrease of telomere length in white matter glial cells. The present findings in normal cerebral tissues will be informative for future studies of telomere stability in the diseased brain. Geriatr Gerontol Int 2018; 18: 1507–1512.
