Resource-efficient piston ring/cylinder liner pairing
Authors: Risse Konstantin , Schorgel Matthias , Bartel Dirk , Karpuschewski Bernhard , Welzel Florian 
Published: December 2018

Purpose
The purpose of this paper is to investigate the influence of different finish processes on the surface integrity and tribological behaviour of cylinder running surfaces for internal combustion engines.

Design/methodology/approach
The cutting force during finishing and the resulting surface topography was measured for a variety of cylinder running surfaces made of EN-GJL-250, EN-GJV-400 and thermal sprayed aluminium alloy. A separate conditioning tool was developed and tested. Different analysis methods (SEM, EDX, SIMS and FIB) for the characterisation of the boundary conditions were used. By an oscillating friction wear test and a single cylinder floating liner engine, the running-in and frictional behaviour was rated.

Findings
It was shown that honing with low cutting forces and silicon carbide cutting material decreases the friction in operation. The characteristics of the boundary layers after running-in depend on the finish machining process. A preconditioning with a separate tool can adjust the boundary layer and running-in behaviour. Based on the experimental results, a multi-body and computational fluid dynamics simulation was developed for the floating liner engine.

Originality/value
The results demonstrate the potential of finishing with low process forces to reduce friction and the need for a complete consideration of the tribological system piston ring/cylinder liner surface.
The stick-slip mechanism for granular flow lubrication
Authors: Meng Fanjing , Liu Kun 
Published: December 2018

Purpose
Granular flow lubrication is developed in recent years as a new lubrication method which can be used in extreme environments, while the stick-slip mechanisms of granular flow lubrication are an urgent obstacle remains unsolved in fully establishing the granular flow lubrication theory.

Design/methodology/approach
A granular flow lubrication research model is constructed by the discrete element method. Using this numerical model, the mesoscopic and macroscopic responses of stick-slip that influenced by the shear velocity, and the influence of the shear velocity and the normal pressure on the vertical displacement are studied.

Findings
Research results show that movement states of granular flow lubrication medium gradually transform from the stick-slip state to the sliding state with increased shear velocity, in which these are closely related to the fluctuations of force chains and friction coefficients between granules. The stick-slip phenomenon comes up at lower shear velocity prior to the appearance of granular lift-off between the two friction pair, which comes up at higher shear velocity. Higher normal pressure restrains the dilatation of the granular flow lubrication medium, which in turn causes a decrease in the displacement.

Originality/value
These findings reveal the stick-slip mechanism of granular flow lubrication and can also offer the helpful reference for the design of the new granular lubrication bearing.

Authors: Tian Daxin , Gong Weiqiang , Liu Wenhao , Duan Xuting , Zhu Yukai , Liu Chao , Li Xin 
Published: December 2018

Purpose
This paper aims to introduce vehicular network platform, routing and broadcasting methods and vehicular positioning enhancement technology, which are three aspects of the applications of intelligent computing in vehicular networks. From this paper, the role of intelligent algorithm in the field of transportation and the vehicular networks can be understood.

Design/methodology/approach
In this paper, the authors introduce three different methods in three layers of vehicle networking, which are data cleaning based on machine learning, routing algorithm based on epidemic model and cooperative localization algorithm based on the connect vehicles.

Findings
In Section 2, a novel classification-based framework is proposed to efficiently assess the data quality and screen out the abnormal vehicles in database. In Section 3, the authors can find when traffic conditions varied from free flow to congestion, the number of message copies increased dramatically and the reachability also improved. The error of vehicle positioning is reduced by 35.39% based on the CV-IMM-EKF in Section 4. Finally, it can be concluded that the intelligent computing in the vehicle network system is effective, and it will improve the development of the car networking system.

Originality/value
This paper reviews the research of intelligent algorithms in three related areas of vehicle networking. In the field of vehicle networking, these research results are conducive to promoting data processing and algorithm optimization, and it may lay the foundation for the new methods.
Intellectual capital management among Italian non-profit socio-cooperatives
Authors: Benevene Paula , Kong Eric , Lucchesi Massimiliano , Cortini Michela 
Published: December 2018

Purpose
The purpose of this paper is to deepen the knowledge on the role played by the intellectual capital (IC) of small and medium non-profit socio-cooperatives (SMSCs) in generating knowledge and organisational growth, as well as on the challenges and the difficulties of the management of IC among these organisations.

Design/methodology/approach
This exploratory study adopted a qualitative methodology. A total of 70 semi-structured interviews were conducted with senior managers of Italian non-profit SMSCs, asking them to talk about the management of their human capital, organisational capital and relational capital. The data gathered from the interviews were analysed through discourse analysis carried out by two independent judges.

Findings
IC management among Italian non-profit SMSCs is unplanned, unsystematic and short-termed. The SMSCs in question adopt an employee-centred approach; their IC management and knowledge creation are more focused on the direct contribution of the organisational members, than on the endorsement of formal or structured procedures and processes. Owing to their social aim, the well-being of both the workers and the beneficiaries of the SMSCs plays a central role in the IC management. Relationships with external stakeholders are regarded as important as those with the internal ones, re-affirming the organisations’ members as the core of the knowledge generation.

Research limitations/implications
The group reached is not a statistically representative sample; furthermore, it is limited to Italy.

Social/implications
Deepening the knowledge on IC among these organisations can help to promote the strengths and address the weaknesses of its management, whilst also helping these micro-enterprises to develop into SMEs.

Originality/value
This paper contributes to the IC literature by shedding light on the role played by IC among small and medium enterprise (SMEs), and more specifically in the specific context of Italian SMSCs. To the authors’ knowledge, no previous research has thus far dealt with this issue. Deepening the knowledge on IC among these organisations can help to promote the strengths and address the weaknesses of its management, while also helping these micro-enterprises to develop into SMEs.
Dividend policy determinants of Sri Lankan firms: a triangulation approach
Authors: Baker H. Kent , Dewasiri N. Jayantha , Yatiwelle Koralalage Weerakoon Banda , Azeez Athambawa Abdul 
Published: December 2018

PurposeThe purpose of this paper is to identify the dividend policy determinants of Sri Lankan firms and why they pay dividends.Design/methodology/approachThe study uses several quantitative approaches to investigate dividend determinants using market (secondary) data of 190 Sri Lankan firms and 1,330 firm-year observations. Dividend determinants are also identified using survey (primary) data from 141 of the 190 firms. Triangulation is then used to facilitate validation of the data through cross-verification from two data sources.FindingsAnalysis of the market data reveals that firm size, industry impact, corporate governance, free cash flow, earnings, past dividends, profitability, investment opportunities, net working capital, concentrated ownership structure and investor preference represent the most important dividend determinants. Survey data confirm these findings. The evidence supports the pecking order, signaling, free cash flow, catering and outcome theories using both secondary and primary data and the bird-in-the-hand theory using survey data.Research limitations/implicationsThe findings are useful not only for corporate decision makers in establishing an appropriate dividend policy but also for shareholders in making investment decisions. Because the current study is limited to Sri Lanka, future researchers should study the same phenomenon in other countries using the triangulation approach.Originality/valueThis study provides a hybrid approach to dividend policy research by using both primary and secondary data in a single study. It is the first dividend study in Sri Lanka to use a triangulation approach.
Winning CSR strategies for the talent war
Authors: Srisuphaolarn Patnaree , Assarut Nuttapol 
Published: December 2018

PurposeThe authors analyze the relationship between perceptions of corporate social responsibility (CSR) activity bundles and prospective employees’ work values to assess how CSR strategies contribute to new staff recruiting strategies.Design/methodology/approachBuilding on personal and organizational value fit theory, the authors propose a positive correlation between facets of work values and particular CSR activities. We use work values, as they reflect personal values, and CSR activities to reflect organizational value. We test this relationship using a sample of senior marketing and international business majors.FindingsThe authors found that the relationships are threefold: all negative, all positive and selectively positive. Some viewed CSR as irrelevant to their choice of employer – those who focused on security and pride, with low degrees of other work values, and those who were concerned with growth and knowledge utilization. People who seek security and meaningful jobs hold preferable attitudes toward CSR, regardless of the areas of CSR. Selectively positive relationship between work values and CSR bundles was founded in those who seek meaningful jobs and the workplaces for which they feel proud to work.Practical implicationsThis paper contributes to better understanding of the influence of CSR on prospective employees over preferences for companies as ideal employers. CSR matters, but not to everyone. Those who perceive that CSR matters are more active regarding work. This study links two topics – personal values through work values, and organizational values through CSR – opening a new area for investigating the effects of CSR on human resource management (HRM).Originality/valueThis study identifies why CSR is attractive to potential employees by using person-value and organizational-value fit theory to elaborate on a company’s social performance through CSR perceptions. No study links these two topics, which examine the same results. Research suggests that fit between personal and organizational values leads to job satisfaction, and thus a tendency to select a specific employer. CSR literature suggests that a company’s reputation gained by engaging in CSR attracts talent. By classifying talent according to work values and mapping them with CSR bundles, the authors argue that there is relationship between types of talent and CSR bundles.
Corporate governance and financial performance for engaging socially and environmentally responsible practices
Authors: Fiandrino Simona , Devalle Alain , Cantino Valter 
Published: December 2018

PurposeThis paper aims to reconcile the conflicting understanding on the nexus between corporate governance (CG), corporate financial performance (CFP) and corporate social responsibility (CSR) by investigating how companies engage with CSR practices.Design/methodology/approachThe study carries out a multivariate linear regression analysis on a sample of 361 listed companies from five countries in Europe: France, Germany, Italy, Spain and the UK.FindingsCG mechanisms and CFP have an impact on CSR because they affect social and environmental practices strongly and significantly. Furthermore, the findings describe the capacity of CSR to influence both the CG structure and the CFP.Research limitations/implicationsThe present research limits the analysis on the social and environmental performance of companies that communicate their commitment to stakeholders without distinguishing between “greenwashing” companies that implement CSR to improve corporate reputation and those companies that pursue effective societal benefits, taking care of stakeholder relationships.Practical implicationsThe CSR approach can drive the CG structure and improve CFP if managers perceive the implementation of sustainable practices as an integrated process rather than a mere outcome.Originality/valueThis paper seeks to disentangle the nexus between CG, CFP and CSR, not yet precisely defined by scholars in the context of five countries in Europe.
Innovation capacity building
Authors: Brix Jacob 
Published: December 2018

PurposeThe purpose of this paper is to propose how a bottom-up creation of an ambidextrous organization can be enabled. By integrating research on “contextual ambidexterity” and “individual and organizational capacity building”, an “innovation capacity building” framework is conceptualized that suggests how balance between exploration and exploitation can be maintained.Design/methodology/approachThe study is conceptual. As no data are utilized, focus is on discussing the links between the two theoretical perspectives and the advantages of the proposed innovation capacity building framework.FindingsThe innovation capacity building framework discusses the influence, both positive and negative, of the local organizational context for ambidexterity, and the interactions required such as feedback between the management team and the employees so they together can build an ambidextrous working culture. A culture in which it is the individual employee that is responsible for switching between activities related to exploration and exploitation and where the management team empowers the employees to do so.Originality/valueThis study focuses on contextual ambidexterity and how contextual ambidexterity can be implemented as a way of working in contemporary organizations. The originality lies in the proposed framework and in the dedicated focus on “how” ambidexterity can be implemented in organizations.
Interlinking Lean and sustainability: how ready are leaders?
Authors: Mårtensson Anna , Snyder Kristen , Ingelsson Pernilla 
Published: December 2018

Purpose
The purpose of this paper is to explore the evidence of interlinkages between Lean and sustainability among organisational leaders in the early stages of Lean implementation.

Design/methodology/approach
A multiple-site case study was conducted to study the connections between Lean and sustainable development during the implementation stages of a Lean practice. In-depth interviews were conducted with managers about their knowledge and understanding of the interlinkages between Lean and sustainable development. The findings were then used as an analytic frame to determine whether these interlinkages were present in the organisation.

Findings
Evidence of interlinkages between Lean and sustainable development was found; however, their presence was incomplete and inconsistent across clinics.

Research limitations/implications
Insights from the research can help organisations plan for the implementation of Lean practice, particularly when a sub-goal is to achieve sustainable development.

Originality/value
The study shows the importance of focussing on managers’ knowledge and understanding of the interlinkages between Lean and sustainable development when implementing Lean in order to utilise Lean’s full potential to achieve sustainability.
A Novel Application of a Cryosectioning Technique to Aid Scat Hair Microanalysis
Authors: Mandoreba Talia Y. , Cloete Karen J. , Minnis‐Ndimba Roya , Kupika Olga L. 
Published: December 2018

AbstractScat hair presents a diverse profile of hairs for morphological assessment that may find versatile applications in wildlife forensic investigations. Successful morphological assessment of scat hair microstructure, however, depends on a robust sectioning methodology. We assessed the feasibility and efficacy of a cryosectioning technique compared to that of a gold standard hand‐sectioning technique. Scat hairs were embedded in paraffin wax and hand‐sectioned, while cryopreserved scat hairs were sectioned with a cryostat. The results showed that cryosectioning preserved the pristine morphology of the scat hair and provided cross sections more amenable to high‐resolution imaging of hair internal microstructure than hand‐sectioning. The cryosectioning technique may find novel applications as a more reliable and robust technique to aid (i) scat hair internal microstructure analysis for cross‐referencing with species identification keys in wildlife forensic studies and (ii) downstream toxicological analysis in wildlife forensic studies as hair biochemistry is not altered during cryopreservation.

Published: December 2018

BackgroundIt has been reported that there are more circulating tumor cells (CTCs) in the pulmonary vein (PV) than in the peripheral blood; however, it is unclear whether the CTC count changes in the PV after resection of a lung lobe.MethodsThirty‐three lung cancer patients were recruited for the study, including 17 who underwent lobectomy via video‐assisted thoracoscopic surgery and 16 via open thoracotomy. Sixty‐six blood specimens were sampled from the PV before the PV was interrupted and after lobectomy. The CTCs were quantified using the oHSV1‐hTERT‐GFP method.ResultsBefore PV interruption, the CTC (pre‐CTC) detection rate was 79.0% (26/33), the mean number of CTCs was 3.36 (median 2, range: 0–18), and there was no significant relationship between the pre‐CTC count and clinical factors, such as histologic findings and pathological T stage (P > 0.05). After lobectomy, the CTC (post‐CTC) detection rate was 100% (33/33), the average number of CTCs was 14.88 (median 11, range: 1–69), and the post‐CTC count was significantly higher in patients in whom the PV was interrupted prior to the pulmonary artery (PA) than in patients in whom the PA was interrupted before the PV (P = 0.016). Overall, the CTC count was significantly higher following surgery (P < 0.001).ConclusionPost‐CTC counts were significantly higher than pre‐CTC counts, suggesting that surgical manipulation may potentially dislodge tumor cells into the PV. Interrupting the PV prior to the PA during lobectomy may prevent partial CTC entry into the circulation.
The association between attention deficit hyperactivity disorder and general anaesthesia ‐ a narrative review
Authors: Xu L. , Hu Y. , Huang L. , Liu Y. , Wang B. , Xie L. , Hu Z. 
Published: December 2018

SummaryAttention deficit hyperactivity disorder is a chronic neurodevelopmental disorder, manifesting primarily as attention deficit, hyperactivity and impulsive behaviour. General anaesthetics can be neurotoxic, affecting neuronal differentiation and synaptogenesis, which can lead to abnormalities of cognition, learning and behaviour. We hypothesise that exposure of the immature brain to general anaesthetics predisposes to the development of attention deficit hyperactivity disorder. In this review, we summarise clinical and animal studies that relate attention deficit hyperactivity disorder to general anaesthesia, by actions on neural molecular mechanisms and neural networks. We also describe potential therapeutic approaches to modulate these effects.
The developing world of pre‐operative optimisation: a systematic review of Cochrane reviews
Authors: du Toit L. , Bougard H. , Biccard B. M. 
Published: December 2018

SummaryPre‐operative optimisation is a heterogenous group of interventions aimed at improving peri‐operative outcomes. To understand the evidence for pre‐operative optimisation in the developing world, we systematically reviewed Cochrane reviews on the topic according to the Human Developmental Index (HDI) of the country where patient recruitment occurred. We used summary statistics and cartograms to describe the HDI, year of publication, timing of pre‐operative intervention and risk of bias associated with each included trial. We assessed the impact of multinational trials on the risk of bias introduced by countries of differing HDI. Four‐hundred and nine trials representing 51 countries and 89,389 randomly allocated participants were summarised in this review. Four‐hundred and nineteen out of 451 (93%) trial populations (i.e. a group of study participants from one country) were from high and very high HDI countries. The median (IQR [range]) HDI of countries were 0.862 (0.806–0.892 [0.445–0.949]). Three of the 409 included trials were multinational, representing 32 countries and 37,736 out of 89,389 (42.2%) included participants. Africa was the least represented continent, with only 4 included trials and 566 participants, of which 62.3% were from one multinational trial. The overall risk of bias was high or unclear in 381 out of 409 (93%) trials. Inclusion of multinational trials decreased the proportion of trial populations introducing high or unclear risk of bias by 9.4% (95%CI 5.1–13.7; p < 0.0001). Half of the world's population live in low‐ and middle‐HDI countries. This population is poorly represented in systematically reviewed evidence on pre‐operative optimisation. Multinational trials increase the knowledge contribution from low‐ and middle‐HDI countries and decrease risk of bias in systematic reviews.

Published: December 2018

AbstractThe purpose of this study was to evaluate the hemodynamic properties and microemboli capture associated with different vacuum‐assisted venous drainage (VAVD) vacuum levels and venous reservoir levels in a neonatal cardiopulmonary bypass circuit. Trials were conducted in 2 parallel circuits to compare the performance of Capiox Baby RX05 oxygenator with separate AF02 arterial filter to Capiox FX05 oxygenator with integrated arterial filter. Arterial cannula flow rate to the patient was held at 500 mL/min and temperature maintained at 32°C, while VAVD vacuum levels (0 mm Hg, −15 mm Hg, −30 mm Hg, −45 mm Hg, −60 mm Hg) and venous reservoir levels (50 mL, 200 mL) were evaluated in both oxygenators. Hemodynamic parameters measuring flow, pressure, and total hemodynamic energy were made in real time using a custom‐made data acquisition system and Labview software. Nearly 10 cc bolus of air was injected into the venous line and gaseous microemboli detected using an Emboli Detection and Classification Quantifier. Diverted blood flow via the arterial filter’s purge line and mean pressures increased with increasing VAVD levels (P < 0.01). Mean pressures were lower with lower venous reservoir levels and were greater in RX05 groups compared to FX05 (P < 0.01). Microemboli detected at the preoxygenator site increased with higher VAVD vacuum levels and lower venous reservoir levels (P < 0.01). The amount of microemboli captured by the FX05 oxygenator with integrated arterial filter was greater than by the RX05 oxygenator alone, although both oxygenators were able to clear microemboli before reaching the pseudo‐patient.
