Cross-emotional infection among multi-flight groups in mass flight delays
Authors: Jia Meng , Yang Yingbao 
Published: December 2016

Purpose
The purpose of this paper is to study dynamic evolution of passenger emotional contagion among different flights emerging in mass flight delays, so as to quantitatively analyze emotional variation tendencies and influences of concerned factors and intervention measures.

Design/methodology/approach
An intervening variable of group emotion was introduced into emotional contagion model to simulate passenger emotional evolution among multi-flight groups. Besides, personalities, characters and social relationships were considered to represent individual differences in emotional changes. Based on personal contact relationships, emotional contagion model was proposed to evaluate cross-emotion transition processes among different groups under scenarios of information shortage. Eventually, evolutionary processes of passenger emotions were fused in an agent-based simulation based on social force correction model.

Findings
Simulation experiment results revealed that passenger emotions suffer from combined impacts of individual emotional changes and emotional interactions among adjacent flights through a comparison with actual survey. Besides, emotional interactions accelerate processes of emotion transitions, and have significant impacts on adjacent flights when different measures are taken. Moreover, taking intervention measures simultaneously seems more effective than implementing intervention successively.

Originality/value
The proposed method makes up for deficiency of ignoring effects of emotional interactions among adjacent flights. It contributes to providing control methods and strategies for relevant departments and improving the efficiency and ability of handling passenger collective events in mass flight delays.
Selection of risk response actions considering risk dependency
Authors: Zhang Yao , Zuo Fei 
Published: December 2016

Purpose
The purpose of this paper is to propose a method to address the problem of selecting risk response actions (RRAs) considering the risk dependency that is seldom considered in the existing studies.

Design/methodology/approach
First, a method based on the Measuring Attractiveness by a Categorical-Based Evaluation Technique (MACBETH) is proposed to measure the dependencies between the risks, and then a preference coefficient denoting the relative importance of the risk dependency is introduced. Besides, an exponential utility function is used to describe the project manager’s (PM) risk-averse behaviour. Finally, a mathematical model that incorporates the risk dependency and risk preference of the PM is constructed for selecting the RRAs.

Findings
Risk dependency plays an important role in the process of RRA selection. First, more expected utility can be obtained when the risk dependency is considered. Second, more attention should be paid to the risk dependency for coping with critical risks when the budget is tight.

Practical implications
This method can be applied to determine the RRAs when the risk dependency exists between the project risks.

Originality/value
This paper proposes a model to select RRAs with consideration of the risk dependency, which is an important issue from a theoretical as well as a practical perspective in project risk management.
Customer credit scoring using a hybrid data mining approach
Authors: Abedini Mohammadali , Ahmadzadeh Farzaneh , Noorossana Rassoul 
Published: December 2016

Purpose
A crucial decision in financial services is how to classify credit or loan applicants into good and bad applicants. The purpose of this paper is to propose a four-stage hybrid data mining approach to support the decision-making process.

Design/methodology/approach
The approach is inspired by the bagging ensemble learning method and proposes a new voting method, namely two-level majority voting in the last stage. First some training subsets are generated. Then some different base classifiers are tuned and afterward some ensemble methods are applied to strengthen tuned classifiers. Finally, two-level majority voting schemes help the approach to achieve more accuracy.

Findings
A comparison of results shows the proposed model outperforms powerful single classifiers such as multilayer perceptron (MLP), support vector machine, logistic regression (LR). In addition, it is more accurate than ensemble learning methods such as bagging-LR or rotation forest (RF)-MLP. The model outperforms single classifiers in terms of type I and II errors; it is close to some ensemble approaches such as bagging-LR and RF-MLP but fails to outperform them in terms of type I and II errors. Moreover, majority voting in the final stage provides more reliable results.

Practical implications
The study concludes the approach would be beneficial for banks, credit card companies and other credit provider organisations.

Originality/value
A novel four stages hybrid approach inspired by bagging ensemble method proposed. Moreover the two-level majority voting in two different schemes in the last stage provides more accuracy. An integrated evaluation criterion for classification errors provides an enhanced insight for error comparisons.
Multi-scale numerical simulation analysis for influence of combined leaching and frost deteriorations on mechanical properties of concrete
Authors: Hu Jiang 
Published: December 2016

Purpose
The multi-scale numerical simulation method, able to represent the complexity of the random structures and capture phase degradation, is an effective way to investigate the long-term behavior of concrete in service and bridges the gap between research on the material and on the structural level. However, the combined chemical-physical deterioration mechanisms of concrete remain a challenging task. The purpose of this paper is to investigate the degradation mechanism of concrete at the waterline in cold regions induced by combined calcium leaching and frost damage.

Design/methodology/approach
With the help of the NIST’s three-dimensional (3D) hydration model and the random aggregate model, realistic 3D representative volume elements (RVEs) of concrete at the micro-, the meso-, and the macro-scales can be reconstructed. The boundary problem method is introduced to compute the homogenized mechanical properties for both sound and damaged RVEs. According to the damage characteristics, the staggering method including a random dissolution model and a thermo-mechanical coupling model is developed to simulate the synergy deterioration effects of interacted calcium leaching and frost attacks. The coupled damage procedure for the frost damage process is based on the hydraulic pressure theory and the ice lens growth theory considering the relationship between the frozen temperature and the radius of the capillary pore. Finally, regarding calcium leaching as the leading role in actual engineering, the numerical methodology for combined leaching and frost damage on concrete property is proposed using a successive multi-scale method.

Findings
On the basis of available experimental data, this methodology is employed to explore the deterioration process. The results agree with the experimental ones to some extent, chemical leaching leads to the nucleation of some micro-cracks (i.e. damage), and consequently, to the decrease of the frost resistance.

Originality/value
It is demonstrated that the multi-scale numerical methodology can capture potential aging and deterioration evolution processes, and can give an insight into the macroscopic property degradation of concrete under long-term aggressive conditions.

Authors: Duran Patricio 
Published: December 2016

PurposeThe purpose of this paper is to offer an institutional perspective of the Martin and Gomez-Mejia model. Specifically, this paper offers arguments of how institutions moderate the socioemotional wealth (SEW) and financial performance relationship.Design/methodology/approachThis is an individual commentary that explores country-level institutional contingencies that affect the predicted effect of SEW dimensions upon financial performance offered by Martin and Gomez-Mejia.FindingsThe paper offers arguments of how both formal and informal institutions, such as the legal protection of minority shareholders, labor and investors; freedom of expression and information; and the country’s culture, exacerbate or ameliorate the predicted effect of the five SEW dimensions upon financial performance.Originality/valueBy exploring an institutional perspective of the socioemotional and financial wealth relationship, this commentary offers additional boundary conditions to those offered by Martin and Gomez-Mejia to further refine their theory.
Understanding the environmental worldviews of Malaysian project managers
Authors: Lau Jasmine Leby , Hashim Ahmad Hariza , Samah Asnarulkhadi Abu , Salim Azizah Salim Syed 
Published: December 2016

Purpose
The purpose of this paper is to examine the dimensionality of the environmental concern scale (NEP) and to understand the environmental worldviews of Malaysian project managers.

Design/methodology/approach
A cross-sectional survey was conducted among developer organisations registered with Real Estate and Housing Developers’ Association Malaysia in Klang Valley. Response was obtained from project managers and the final sample collected was 87 cases, representing a response rate of 24.5 per cent. Principal component analysis with varimax rotation was conducted to investigate the underlying structure of the NEP items while frequency distribution for the data set was used to gauge the environmental worldviews of the respondents. In addition, face-to-face interviews were carried out to gather more information to complements the findings of quantitative analyses.

Findings
Five factors were extracted but due to heavy cross-loadings, two items from the original scale were dropped, reducing it to be a 13-item scale. The four factors retained explained 61.6 per cent of the variance and were duly named Human over nature, ecocrisis, rights of nature and limits of growth. High scores on both pro-NEP and pro-dominant social paradigm items revealed the co-existence of both ecological and utilitarian view of the environment among project managers. Similar outcome was obtained from interviews with project managers where they indicated efforts in finding compatibility between protecting the environment and exploiting natural resources for development.

Research limitations/implications
The sample was restricted to housing developers in Klang Valley, thus the findings cannot be generalised to all developer organisations or other construction occupational groups.

Practical implications
This research supported the multidimensionality claim of the environmental scale (NEP) where four distinctive dimensions were identified. The usage of individual subscales in understanding environmental beliefs may reveal interesting patterns in that each dimension could have positive and negative connotations on human behaviours. In addition, the co-existence of both an ecological and a utilitarian view of the environment revealed that these worldviews align well with sustainable development principles.

Originality/value
This study is one of the few local studies that attempt to understand the environmental worldviews of project managers.
Gestating times: women's accounts of the temporalities of pregnancies that end in abortion in England
Authors: Beynon‐Jones Siân M. 
Published: December 2016

AbstractTensions between the ‘clock time’ of medicine and the embodied times of its subjects are central to feminist writing concerning Western obstetric practice. In this article, I expand the focus of this literature by addressing the temporal dynamics of another site of reproductive healthcare: abortion provision. Echoing obstetric accounts of birth, time in legal, healthcare and social scientific discourse on abortion is routinely conceptualised as a finite resource contained within the pregnant/foetal body, which can be measured using clocks and calendars. I argue that women's interview accounts of their experiences of ending their pregnancies offer opportunities for critical reflection on this characterisation of pregnancy as linear ‘gestational time’. First, participants in this study re‐position the significance of gestational time by articulating its embodied meaning. Second, they provide alternative accounts of the temporality of pregnancy as a process which emerges through, and is disrupted by, the dynamics of socio‐material relations. The article considers the broader implications of women's accounts of pregnancy times for legal, healthcare and social scientific accounts of ‘later’ abortion.
The Effect of Certificate of Need Laws on All‐Cause Mortality
Authors: Bailey James 
Published: December 2016

ObjectiveTo test how Certificate of Need laws affect all‐cause mortality in the United States.Data SourcesThe data of 1992–2011 all‐cause mortality are from the Center for Disease Control's Compressed Mortality File; control variables are from the Current Population Survey, Behavioral Risk Factor Surveillance System, and Area Health Resources File; and data on Certificate of Need laws are from Stratmann and Russ ().Study designUsing fixed‐ and random‐effects regressions, I test how the scope of state Certificate of Need laws affects all‐cause mortality within US counties.Principal FindingsCertificate of Need laws have no statistically significant effect on all‐cause mortality. Point estimates indicate that if they have any effect, they are more likely to increase mortality than decrease it.ConclusionsProponents of Certificate of Need laws have claimed that they reduce mortality by concentrating more care into fewer, larger facilities that engage in learning‐by‐doing. However, I find no evidence that these laws reduce all‐cause mortality.

ObjectiveTo identify roles physicians assumed as part of new health care delivery models and related strategies that facilitated physician engagement across 21 Health Care Innovation Award (HCIA) programs.Data SourcesSite‐level in‐depth interviews, conducted from 2014 to 2015 (N = 672) with program staff, leadership, and partners (including 95 physicians) and direct observations.Study DesignNORC conducted a mixed‐method evaluation, including two rounds of qualitative data collected via site visits and telephone interviews.Data Collection/Extraction MethodsWe used qualitative thematic coding for data from 21 programs actively engaging physicians as part of HCIA interventions.Principal FindingsEstablishing physician champions and ensuring an innovation‐values fit between physicians and programs, including the strategies programs employed, facilitated engagement. Among engagement practices identified in this study, tailoring team working styles to meet physician preferences and conducting physician outreach and education were the most common successful approaches.ConclusionsWe describe engagement strategies derived from a diverse range of programs. Successful programs considered physicians' values and engagement as components of process and policy, rather than viewing them as exogenous factors affecting innovation adoption. These types of approaches enabled programs to accelerate acceptance of innovations within organizations.
Adsorption as a Contributor for Inflammatory Mediators Removal by Different Hemofiltration Membranes: A Pilot Study
Authors: Malard Benjamin , Florens Nans , Lambert Corine , Juillard Laurent 
Published: December 2016

AbstractAtherosclerosis is an important predictor of mortality in patients with chronic kidney disease (CKD) and is associated with a wide inflammatory response. The aim of this study is to evaluate in vitro how different membranes can remove mediators associated with this pathology in a closed loop dialysis model. We performed experimental hemofiltration in vitro using three different membrane materials. Human plasma was preliminarily incubated with various inflammatory mediators and filtered in a closed loop circulation model for 240 min. Respective concentrations of 17 different mediators were measured over time to study the removal mechanisms of each membrane, including associated removal time course. The experiment was repeated three times for the assay of tumor necrosis factor (TNF)‐α to document the model variability. Means were compared using Mann–Whitney test. Most of the investigated mediators were effectively removed with the different dialysis membranes. Adsorption mechanism was mainly at the origin of the decrease in mediators circulating concentrations and was maximized in the region 10 000–20 000 Da. Especially, the HeprAN membrane showed fast removal capacities of mediators with elevated isoelectric point including complement factors and chemokines or having basic groups located in the protein periphery, plasminogen activator inhibitor (PAI‐1), and TNF‐α‐like. The latter was further significantly removed with HeprAN and polymethylmethacrylate (PMMA) compared to polyethersulfone (PES) material (P < 0.01). We concluded that dialysis using ionic adsorptive membrane could have a beneficial impact for CKD patients with atherosclerosis and would deserve further clinical investigations.
Skull shape variation in extant and extinct Testudinata and its relation to habitat and feeding ecology
Authors: Foth Christian , Rabi Márton , Joyce Walter G. 
Published: December 2016

AbstractTurtles (Testudinata) are a diverse group of reptiles that conquered a broad set of habitats and feeding ecologies over the course of their well‐documented evolutionary history. We here investigate the cranial shape of 171 representatives of the turtle lineage and the relationship of shape to different habitat and diet preferences using two‐dimensional geometric morphometrics. The skull shape of extant turtles correlates with both ecological proxies, but is more affected by habitat than diet. However, the application of these correlations to extinct turtles produces mostly flawed results, as least when compared to external data such as sedimentary environment, highlighting that the morphospace held by extant turtles is not necessarily the optimal location in tree space for a particular ecology. The inability of this study to correctly predict the ecology of extinct turtles is likely related to the fact that the shape of turtle skulls is dominated by the emarginations and jaw closure mechanisms, two shape features unrelated to habitat or feeding ecology. This indicates that various specializations that are apparent in the skull only contribute little to overall shape.

Published: December 2016

ObjectivesFew studies have investigated service user satisfaction with cognitive behavioural therapy for psychosis (CBTp). This study explored its associations with clinical presentation and outcomes, retrospective expectations of progress, perceptions of the therapist, and demographic variables.Design and methodsOne hundred and sixty‐five service users completed self‐report questionnaires pre‐ and post‐CBTp in relation to the constructs of interest. Regression analyses explored associations with (1) overall satisfaction with therapy and (2) perceived progress, skills, and knowledge gained.ResultsNinety‐six per cent of service users reported satisfaction with therapy. Higher levels of overall satisfaction with, and perceived benefit from, therapy were associated with positive therapy expectations, positive ratings of therapist's personal qualities, competence and trustworthiness, lower pre‐therapy depression, and improvements in quality of life. Symptom improvements were not related to overall satisfaction with therapy; however, with the exception of voices, better clinical outcomes were associated with subjective ratings of having made more progress and gained more CBT skills and knowledge. Demographic factors were not associated with satisfaction or perceived progress. In multiple regression analyses, expectations of progress showed the strongest associations with both satisfaction and perceived benefits. Other remaining significant associations consisted of perceptions of the therapist for satisfaction, and both pre‐therapy levels of, and changes in, depression for perceived benefits. Qualitative feedback emphasized the importance of the therapeutic relationship and developing new coping strategies.ConclusionsThe findings provide preliminary evidence that high levels of satisfaction with therapy are not contingent on good clinical outcomes and are instead associated with positive therapy expectations and perceptions of the therapist.Practitioner points

Therapy expectations represent a neglected area of research and may have implications for levels of satisfaction with therapy and perceived benefit.

The findings reinforce the importance of cognitive behavioural therapy for psychosis (CBTp) therapists demonstrating that they are supportive, competent, and trustworthy.

The findings suggest that positive experiences of therapy do not require changes in psychosis symptoms and are instead related to changes in quality of life.

Depressive symptoms at the start of therapy may adversely influence the extent to which CBT skills and knowledge are gained and levels of perceived progress at the end of therapy.

The present sample was restricted to service users who completed therapy.

Satisfaction levels were high. Further research is needed to explore factors associated with dissatisfaction with therapy.
