Performance characteristics of rectangular aerostatic thrust bearing by conformal mapping
Authors: Gao Shang-Han , Nong Sheng-Long 
Published: September 2018

Purpose
This paper aims to analyze the pressure distribution of rectangular aerostatic thrust bearing with a single air supply inlet using the complex potential theory and conformal mapping.

Design/methodology/approach
The Möbius transform is used to map the interior of a rectangle onto the interior of a unit circle, from which the pressure distribution and load carrying capacity are obtained. The calculation results are verified by finite difference method.

Findings
The constructed Möbius formula is very effective for the performance characteristics researches for the rectangular thrust bearing with a single air supply inlet. In addition, it is also noted that to obtain the optimized load carrying capacity, the square thrust bearing can be adopted.

Originality/value
The Möbius transform is found suitable to describe the pressure distribution of the rectangular thrust bearing with a single air supply inlet.
Predicting World Heritage site visitation intentions of North American park visitors
Authors: Halpenny Elizabeth , Kono Shintaro , Moghimehfar Farhad 
Published: September 2018

Purpose
World Heritage sites (WHS) can play an important role in promoting visitation to emerging and remote destinations. Guided by the theory of planned behaviour (TPB), this study aims to investigate factors that predict intentions to visit WHS.

Design/methodology/approach
Survey questionnaires were used to collect data from visitors (n = 519) to four Western North American WHS. Partial least squares structural equation modelling (PLS-SEM) was used to identify three reflective models (attitude toward visiting World Heritage, perceived behavioural control and intention to visit WHS in the future), three formative models (attitude toward World Heritage designation, social influence (subjective norms) to visit World Heritage and World Heritage tourism brand equity) and a structural model.

Findings
World Heritage tourism brand equity and social influence were strong positive predictors of intentions to visit WHS in the future. Attitudes towards World Heritage designation, followed by World Heritage travel attitudes and perceived behavioural control, were progressively weaker, yet positive predictors. However, the latter two concepts’ impact was negligible.

Originality/value
This study addresses four deficiencies in tourism studies: TPB studies have failed to find consistent predictors of intentions to visit destinations; very few studies have attempted to verify the factors that predict visitation to WHS, despite the opportunities and costs that can arise from WHS-related tourism; few studies of tourists’ perceptions of World Heritage and related WHS travel intentions have been conducted in North America; and PLS-SEM was used to perform statistical methods not commonly used in tourism studies including formative models, importance-performance mapping and confirmatory tetrad analysis.
The power of information on customers’ social withdrawal and citizenship behavior in a crowded service environment
Authors: Wei Shuqin , Ang Tyson , Anaza Nwamaka A. 
Published: September 2018

PurposeCrowding in service environments is a constant concern for many firms due to the negative consequences it has on consumers and companies alike. Yet, scant empirical research exists on firm-generated initiatives aimed at improving customer service experiences in crowded situations. The purpose of this paper is to investigate how information, a managerially actionable variable, influences social interactions (in the form of customer social withdrawal and citizenship behavior) and service experience.Design/methodology/approachTwo experimental studies were conducted using an extended service context.FindingsThis research demonstrates that receiving information about crowds in advance results in heightened social withdrawal, which improves customer service experience. However, providing consumers with a platform to share crowding information increases customers’ citizenship behavior toward service employees and other customers, which, in turn, improves customer service experience.Practical implicationsFor extended service encounters (e.g. air travel) where social interactions are inevitable, companies should encourage customers to share their real-time experiences with other customers in hopes of creating more positive social interactions (e.g. citizenship behavior) within the crowded environment.Originality/valueExisting investigations of crowding stem from an overemphasis on the physical and atmospheric aspects of the environment by treating crowds as a “fixture” in the servicescape, rather than as “active participants” involved in the crowding environment. While the mere presence of crowds alone has negative effects, this research takes it a step further by examining interactions among and between customers and service employees within the crowded service environment.

Authors: Hourneaux Jr Flavio , Gabriel Marcelo Luiz da Silva , Gallardo-Vázquez Dolores Amalia 
Published: September 2018

Purpose
The purpose of this paper is to propose a minimum set of indicators to be measured by industrial companies to represent the triple bottom line (TBL) approach.

Design/methodology/approach
The research is both descriptive and quantitative. Three hypotheses establish associations among the degrees of use of TBL indicators and their different degrees of use in firms. The authors used confirmatory factor analysis (CFA) to validate the scale and structural equation modelling to represent the final measurement model. The survey gathered 149 industrial companies.

Findings
The results pointed out that there are positive associations among the degree of use of environmental indicators and social indicators, economic, environmental and social indicators have different degrees of use in firms, a positive association between the degree of use of environmental and social indicators and the use of economic indicators was not confirmed. The findings suggest how to measure sustainable performance for industrial companies and highlight the differences in the degree of use for the three dimensions of TBL.

Research limitations/implications
The limitations refer to the non-probabilistic sample, applied in a specific context, industrial companies.

Practical implications
This set of indicators is intended to be used by industrial companies as a reliable instrument to sustainable performance assessment of the current stage of the TBL deployment and provide alternative approaches to address specific issues related to the environmental, social and economic sustainability.

Social implications
The results offer tangible results for measuring and reporting firm’s social and environmental performance.

Originality/value
This paper intends to offer an integrated and consistent way of measuring sustainability in industrial companies.
Criteria and barriers for the application of green building features in Hong Kong
Authors: Wadu Mesthrige Jayantha , Kwong Ho Yuk 
Published: September 2018

Purpose
An understanding about the criteria determining the successful application of green features, and the barriers to implementation is essential in order to promote and enhance green building development. The purpose of this paper is twofold: first, the criteria determining the success of GBFs; and second, the barriers to implementing GBFs in Hong Kong.

Design/methodology/approach
A multi-method approach comprising a comprehensive questionnaire survey and a semi-structured group discussion with construction professionals, along with three case studies was adopted to address these two issues.

Findings
Findings suggest that although environmental performance is the most significant criterion, the living quality of occupants and the costs of green features play a crucial role in determining the success of their application. However, the environmental aspects of buildings are not sufficient for rating or determining the greenness level of a building. As for barriers, the green cost implications; the structural unsuitability of the current stock of old buildings; and the lack of financial incentives were found to be crucial barriers preventing the application of green features in the Hong Kong building sector.

Originality/value
GBFs have received extensive attentions by the academia and industry. This paper used a mix method approach by exploring success criteria and barriers to implementing green features in the building sector in Hong Kong. As green building development is still a contemporary subject of discussion, this study would be beneficial to decision makers as it identifies the criteria determining the success of green building adoption and barriers to implementation of such features. Hence, relevant stakeholders will have better understanding of the factors affecting the adoption of GBFs.
Linking process and effects of intersectoral action on local neighbourhoods: systemic modelling based on Actor–Network Theory
Authors: Bilodeau Angèle , Galarneau Marilène , Lefebvre Chantal , Potvin Louise 
Published: September 2018

AbstractAfter 25 years of intersectoral practice to increase health promotion resources, there is little scientific literature linking analysis of processes to observation of effects. Applying Actor–Network Theory, this article examines how the effects of intersectoral action are produced and can be attributed to its processes. A prospective multiple case study (2013–2016) was conducted on Neighbourhood Committees (NCs) in Montreal (Canada). Three NCs were studied using four kinds of data: direct observation notes of meetings and events, documents, logbooks and interviews. Systemic modelling of local intersectoral action was used for data collection and analysis. The results show that the transformations in living environments were produced by sequences of a limited number of ‘transitory outcomes’ that mark the progression of intersectoral action up to its effects. The list of transitory outcomes identified make up three functions in the production of change: (i) network setup and governance; (ii) self‐representing and influencing others; (iii) aligning necessary actors and resources. The production of effects follows a systemic model wherein unique configurations of transitory outcomes, adapted to the different contexts where interactions are occurring, represent the change processes that lead to the effects.

Published: September 2018

AbstractThe Jiangla'angzong granite in the northern part of the Central Lhasa Terrane is composed of syenogranite and adamellite. LA‐ICP‐MS zircon U‐Pb analyses suggest that syenogranite has a weighted mean 206Pb/238U age of 86±1 Ma (mean square weighted deviation=0.37), which is in accordance with the muscovite Ar‐Ar age (85±1 Ma) of Cu‐Au ore‐bearing skarns and the zircon U‐Pb age (84±1 Ma) of adamellite. This suggests that the Jiangla'angzong magmatism and Cu–Au mineralization events took place during the Late Cretaceous. The granite contains hornblende, biotite, and pyroxene, and does not contain Al‐bearing minerals, such as muscovite, cordierite, and garnet. It has high contents of SiO2 (65.10–70.91wt%), K2O (3.44–5.17wt%), and total K2O+Na2O (7.13–8.15wt%), and moderate contents of A12O3 (14.14–16.45wt%) and CaO (2.33–4.11wt%), with a Reitman index (σ43) of 2.18 to 2.33, and A/CNK values of 0.88 to 1.02. The P2O5 contents show a negative correlation with SiO2, whereas Pb contents show a positive correlation with SiO2. Th and Y contents are relatively low and show a negative correlation with the Rb contents. These characteristics suggest that the Jiangla'angzong granite is a high K calc–alkaline metaluminous I–type granite. It is enriched in light rare earth elements (LREE) and large ion lithofile elements (LILE), and depleted in heavy rare earth elements (HREE) and high field strength elements (HFSE), with LREE/HREE ratios of 11.7 to 18.1. The granite has negative Eu anomalies of 0.58 to 0.94 without obvious Ce anomalies (δCe=1.00–1.04). The relatively low initial 87Sr/86Sr ratios of 0.7106 to 0.7179, positive εHf(t) values of 1.0 to 4.1, and two‐stage Hf model ages (TDM2) ranging from 889 Ma to 1082 Ma, These geochemical features indicate that the granite derived from a juvenile crust. The (143Nd/144Nd)t values from the Jiangla'angzong granite range from 0.5121 to 0.5123, its εNd(t) values range from –10.17 to –6.10, its (206Pb /204Pb)t values range from 18.683 to 18.746, its (207Pb /204Pb)t values range from 15.695 to 15.700, and its (208Pb /204Pb)t values range from 39.012 to 39.071. These data indicate that the granite was formed by melting of the upper crust with the addition of some mantle materials. We propose that the Jiangla'angzong granite was formed during the post‐collision extension of the Qiangtang and Lhasa terranes.
Metallogeny of the Baiyangping Lead‐Zinc Polymetallic Ore Concentration Area, Northern Lanping Basin of Yunnan Province, China

Published: September 2018

AbstractThe Lanping Basin in the Nujiang‐Lancangjiang‐Jinshajiang (the Sanjiang) area of northeastern margin of the Tibetan Plateau is an important part of eastern Tethyan metallogenic domain. This basin hosts a number of large unique sediment‐hosted Pb‐Zn polymetallic deposits or ore districts, such as the Baiyangping ore concentration area which is one of the representative ore district. The Baiyangping ore concentration area can be divided into the east and west ore belts, which were formed in a folded tectogene of the India‐Asia continental collisional setting and was controlled by a large reverse fault. Field observations reveal that the Mesozoic and Cenozoic sedimentary strata were outcropped in the mining area, and that the orebodies are obviously controlled by faults and hosted in sandstone and carbonate rocks. However, the ore‐forming elements in the east ore belt are mainly Pb‐Zn‐Sr‐Ag, while Pb‐Zn‐Ag‐Cu‐Co elements are dominant in the west ore belt. Comparative analysis of the C‐O‐Sr‐S‐Pb isotopic compositions suggest that both ore belts had a homogeneous carbon source, and the carbon in hydrothermal calcite is derived from the dissolution of carbonate rock strata; the ore‐forming fluids were originated from formation water and precipitate water, which belonged to basin brine fluid system; sulfur was from organic thermal chemical sulfate reduction and biological sulfate reduction; the metal mineralization material was from sedimentary strata and basement, but the difference of the material source of the basement and the strata and the superimposed mineralization of the west ore belt resulted in the difference of metallogenic elements between the eastern and western metallogenic belts. The Pb‐Zn mineralization age of both ore belts was contemporary and formed in the same metallogenetic event. Both thrust formed at the same time and occurred at the Early Oligocene, which is consistent with the age constrained by field geological relationship.

Published: September 2018

AbstractTo investigate the influence of extractable organic matter (EOM) on pore evolution of lacustrine shales, Soxhlet extraction, using dichloromethane, was performed on a series of Chang 7 shale samples (Ordos Basin, China) with vitrinite reflectance of 0.64% to 1.34%. Low‐pressure gas adsorption experiments were conducted on the samples before and after extraction. The pore structure parameters were calculated from the gas adsorption data. The results show complex changes to the pore volumes and surface areas after extraction. The pore development of both the initial and extracted samples is strongly controlled by total organic carbon (TOC) content. Micropores developed mainly in organic matter (OM), while mesopores and macropores predominantly developed in fractions other than OM. The influence of EOM on micropores is stronger than on mesopores and macropores. Organic solvents with a higher boiling point should be used to explore the effect of EOM on pore structure in the future.
A Preliminary Study on the Soft–Sediment Deformation Structures in the Late Quaternary Lacustrine Sediments at Tashkorgan, Northeastern Pamir, China
Authors: LIANG Lianji , DAI Fuchu , JIANG Hanchao , ZHONG Ning 
Published: September 2018

AbstractThis study identified soft–sediment deformation structures (SSDS) of seismic origin from lacustrine sediments in the late Quaternary paleo–dammed lake at Tashkorgan, northeastern Pamir. The observed deformation structures include sand dykes, liquefied diapir and convolute structures, gravity induced SSDS, and thixotropic pillar and tabular structures. We conducted a preliminary study on the morphology, formation and trigger mechanisms of pillar and tabular structures formed by liquefaction of underlying coarse sand and thixotropy of the upper silty clay. The regional tectonic setting and distribution of lacustrine strata indicate that the most probable trigger for the SSDS in lacustrine sediments was seismic activity, with an approximate earthquake magnitude of M>6.0; the potential seismogenic fault is the southern part of the Kongur normal fault extensional system. AMS14C dating results indicate that the SSDS were formed by seismic events occurring between 26050±100 yrBP and 22710±80 yrBP, implying intense fault activity in this region during the late Pleistocene. This study provides new evidence for understanding tectonic activity and regional geodynamics in western China.
Effect of External Support on Bank Default and Operating Risks: Does Country Strength Matter?
Authors: Shen Chung‐Hua , Huang Yu‐Li , Lin Kun‐Li 
Published: September 2018

AbstractThis study investigates how two forms of external support, namely, government and foreign ownership, affect bank default and operating risks. The results show, first, that government ownership reduces default risk and increases operating risk, while foreign ownership reduces both default and operating risks. Second, government ownership decreases default risk especially for banks from advanced countries and countries with better national governance. Third, foreign ownership from countries with better sovereign ratings decreases both default and operating risks. Our results suggest that Asian countries should increase income or national governance for more effective government support and open the domestic bank market.
Triangular No‐arbitrage Estimation through Bitcoin: An Application in Venezuelan Bolivars
Authors: Wang Jying‐Nan , Hsu Yuan‐Teng , Chen Chih‐Chun 
Published: September 2018

AbstractIn this study, we apply the Bitcoin to estimate the price of the Venezuelan bolivar, due to the unreliability of this currency's official exchange rate. Our approach is based on the triangular no‐arbitrage condition and takes the Bitcoin as an intermediate currency. To verify its validity, in addition to bolivars, six currencies are first considered in the empirical study. We find that trading through the Bitcoin market produces higher transaction costs or requires higher risk compensation than trading through the conventional exchange market. Then, we explore the Venezuelan case. Comparing the estimates of the black market bolivars, which are generated from several popular media sources and the Web site Dolartoday.com, using Bitcoin can produce reliable bolivar exchange rates quickly and easily. To sum up, we verify the feasibility of using the triangular no‐arbitrage condition in foreign exchange markets to estimate exchange rates through the Bitcoin. This is especially useful when capital controls exist such as they do in Venezuela.

Published: September 2018

AbstractDecellularized (DC) organs/tissues offer a promising scaffold for regenerative bioengineering. However, it is not clear whether the diabetic mellitus (DM) pancreas can be used in decellularized and recellularized bioengineering. For assessment of these questions, murine pancreatic scaffolds of normal, type 1DM (T1DM) and type 2 DM (T2DM) pancreas were generated using a perfusion decellularization technique and assessed by histology, scanning electron microscopy, immunohistochemistry, and enzyme‐linked immunosorbent assay (ELISA). The capacity of DC pancreatic scaffolds to support attachment and proliferation of human umbilical vein endothelial cells (HUVECs) and MIN‐6 β cells was also assessed. Our results showed that DC pancreatic scaffolds were successfully produced from T1DM and T2DM pancreas and maintained their extracellular matrix (ECM) composition, 3D ultrastructure, and various cytokines. All of the pancreatic scaffolds were sufficiently cytocompatible and were able to support proliferation and adhesion of HUVECs and MIN‐6 β cells. The preliminary results support the biological utility of diabetes mellitus pancreatic scaffolds and pave the way for further investigations to assess the potential ability of using diabetes mellitus pancreas as scaffolds for recellularization and eventual medical applications.

Authors: Poorkhali Ali , Bizari Davood , Farrokhzad Hasan 
Published: September 2018

AbstractA new extracorporeal circuit for hemodialysis was designed with the goal of improving the middle and high molecular weight toxins removal. A recirculation pathway was added to the hemodialysis circuit and relevant pressure regulation was performed along the circuit in order to keep the ultrafiltration rate as zero. The influence of increasing the recirculation to dialysate flow rate ratio on the removal of urea, vitamin B12, and hemoglobin was investigated. This removal was also modeled by an analytical method and solved by MATLAB software. A significant increase in removal of vitamin B12 (34%) and especially hemoglobin (228%) was achieved using the recirculation flow in an adjusted hemodialysis circuit. The model showed an acceptable agreement with the experimental results which shows its applicability for prediction of different toxin removal in this circuit.
