A model for project team formation in complex engineering projects under uncertainty
Authors: Hosseini S. Mahdi , Akhavan Peyman 
Published: June 2017

Purpose
This paper aims to develop a model for selecting project team members. In this model, while knowledge sharing among individuals is maximized, the project costs and the workload balance among employees are also optimized.

Design/methodology/approach
The problem of project team formation is formulated as a fuzzy multi-objective 0-1 integer programming model. Afterward, to deal with uncertainty in the decision-making on the candidates’ abilities and the project requirements, the fuzzy multi-objective chance-constrained programming approach is adopted. Finally, by combining the non-dominated sorting genetic algorithm II and the fuzzy simulation algorithms, a method is proposed to solve the problem.

Findings
The computational results of the proposed model in a case study of project team formation in a large Iranian company from the shipbuilding industry evidently demonstrated its effectiveness in providing Pareto-optimal solutions for the team composition.

Originality/value
Seemingly for the first time, this paper develops a model to optimize knowledge sharing and improve the project efficiency through the selection of appropriate project team members.
The Bayesian quantile regression and rough set classification
Authors: Wu Shianghau , Guo Jiannjong 
Published: June 2017

Purpose
In this paper, the authors aim to propose to find the variables that affect the Taiwanese people’s satisfaction level of the general public with the government.

Design/methodology/approach
The authors intend to utilize the Bayesian quantile regression to explore the variables that affect the satisfaction of the general public at specific quantiles of Taiwanese satisfaction with the government and rough set classification to explore key variables related to the satisfaction level. Then they make the comparison of the classification among the two methods to obtain the performance of the classification.

Findings
The experiment result shows the major factors which have the positive relationship with the people who have higher satisfaction level with the central government. These factors include satisfaction with the uncorrupted performance of the central government; the evaluation of household’s economic condition one year after the present time; the satisfaction with the Taiwanese central government’s measures on food safety and the satisfaction with the 12 years primary education reform.

Originality/value
The study’s originality hinges on the application of Bayesian quantile regression and rough set classification to the analysis of the Taiwanese satisfaction with the government. It offers more insights on the key variables related to different satisfaction level and the classification performance between the two methods.

Purpose
The purpose of this paper is to demonstrate the existence of one suitable oxide phase concurrent with deposition for fabricating a titanium (Ti)/p-silicon (Si) Schottky diode by direct current (DC) magnetron sputtering method.

Design/methodology/approach
In this paper, a Ti/p-Si Schottky diode has been fabricated by depositing a Ti film on p-Si substrate by DC magnetron sputtering. Electrical properties of a Schottky junction include three main parameters: ideality factor (n), series resistance (Rs) and barrier height (Φb), which were determined by three analysis methods: current–voltage (I-V), Cheung function and Norde function.

Findings
As result outcomes of the calculated values by three analysis methods, average values were obtained equal to 2.475, 27.07 kÙ and 0.88 ev. With comparing direct calculation of series resistance with the achieved average value of three analysis methods, it illustrates that without X-ray diffraction (XRD) analysis consideration, it’s possible to deduce at least one oxide phase forming on the Ti layer.

Originality/value
This work fabricates Ti/p-Si Schottky diode by DC magnetron sputtering. By use of downward-arch region of the LnI-V curve, two functions that are known as Norde and Cheung were made with which this study applies these functions and linear region of LnI-V plot each values of n, Φb and Rs, except n calculated two times. With comparison of calculated values from two parts of plot, it is clear that Norde and Cheung functions are accurate and the applied method is correct. Also, with direct calculation, the value of Rs and as compared with result from analysis, this study has proved that without XRD plot, certainly simultaneity deposition at least one oxide phase was forming on Ti layer.
Finite element method simulation of phase transformations during cooling of 55SiMnMo steel
Authors: Yan Tao , Ma Liang , Zhao Shuo , Yu Enlin 
Published: June 2017

Purpose
This study aims to focus on numerical simulation investigations of phase transformation during cooling of 55SiMnMo steel, which is commonly applied to improve mechanical properties.

Design/methodology/approach
A mathematical model based on the finite element method (FEM) and the phase transformation kinetics model has been proposed to predict microstructure changes during continuous cooling of 55SiMnMo steel. This model can be employed to analyze the variation of austenite, special upper bainite and lump-like composite structure with cooling time at different cooling rates.

Finding
According to the continuous cooling experiments, when the cooling rate is lower than 0.1°C/s, the special upper bainite is the only transformation product which decreases with increasing cooling rate; when the cooling rate is above 0.5°C/s, the transformation products include special upper bainite and lump-like composite structure. Meanwhile, the results of continuous cooling experiment verified the correctness of this finite element model.

Originality/value
This model has a great value for proper controlling of the cooling process which can improve the quality of hollow drill steel and increase the service life of the final product.
The silencing effects of the childhood innocence ideal: the perceptions and practices of fathers in educating their children about sexuality
Authors: Bennett Clare , Harden Jane , Anstey Sally 
Published: June 2017

AbstractThis study employed Interpretative Phenomenological Analysis to explore eight fathers’ perceptions and practices in talking to their ten year old children about puberty, relationships and reproduction. The fathers participated in face to face interviews which were analysed idiographically initially, followed by analysis at the group level. Interpretations were then developed through critical application of a Foucauldian lens of governmentality and biopower. The results revealed a tension between the fathers’ cognitions, accounts and behaviours. Their practices were largely characterised by silence yet they reported positive attitudes towards children's sexuality education and perceived themselves as equipped and willing to take on the role of sexuality educator. They also reported enjoying open relationships with their children. Interpretations centred on contradictions and conflict between the majority of the fathers’ aspirations and the compelling nature of the childhood innocence discourse as a technology of governmentality. Whilst all of the fathers felt that it was in their children's interests to learn about sexuality, all but one adhered to hegemonic protective discourses and unquestioningly integrated their normalising effects into their fathering practices which, it is argued, may paradoxically render their children more vulnerable both now and in the future.
Negotiating the Politics of Exclusion: Georges Candilis, Housing and the Kuwaiti Welfare State
Authors: Al‐Ragam Asseel 
Published: June 2017

AbstractIn the early stages of welfare planning, the Kuwaiti state restricted equal access to its housing programs in neighborhoods outside the city. The subsequent demographic shift, caused by a Kuwaiti exodus to the ‘suburbs' and non‐Kuwaiti urban labor migration, prompted calls for housing schemes to encourage city living for citizens. Georges Candilis's proposal for a residential neighborhood in Kuwait City emerged from this context. This article examining Candilis's unrealized project also offers a critical perspective on Kuwait's unbalanced housing policies. From this analysis, it draws observations on the role of architects and their limited impact on policies established by decision‐making networks within the welfare state. Seen from this perspective, the Candilis project bears witness to broader socio‐economic agendas that privileged some groups while marginalizing or excluding others.

Published: June 2017

AbstractAimOlive oil was used in the past as a remedy for many diseases due to its unlimited benefits in health. This study was carried out to assess the analgesic, anti‐pyretic and anti‐inflammatory activities of extra virgin olive oil (EVOO) at a dose of 8 mL/kg body weight and to compare it with ibuprofen (IBU) as an individual drug therapy and in combination with two different doses of IBU (therapeutic dose 100 mg/kg and low dose 40 mg/kg), on different animal models in albino mice.MethodA total of 132 adult healthy male Swiss albino mice were used in this study. The analgesic effect was assessed using acetic acid‐induced writhing test. The antipyretic effect was evaluated by brewer's yeast‐induced pyrexia, while the anti‐inflammatory activity was assessed by two different models; the carrageenan‐induced paw edema and the carrageenan‐induced peritonitis in which the levels of total leukocyte count (TLC), neutrophil count, prostaglandin E2 (PGE2) and interferon gamma (INF‐γ) were measured in the peritoneal exudates.ResultsThe results revealed significant protection in all the treated groups; however, the combination of EVOO with IBU at its therapeutic dose showed superiority over the two compounds when used separately.ConclusionUsing EVOO with the therapeutic dose of IBU showed synergistic effect in controlling the cardinal signs of acute inflammation rather than using non‐steroidal anti‐inflammatory drugs alone.
It's worth the wait: optimizing questioning methods for effective intraoperative teaching

Published: June 2017

BackgroundThe use of questioning to engage learners is critical to furthering resident education intraoperatively. Previous studies have demonstrated that higher level questioning and optimal wait times (>3 s) result in learner responses reflective of higher cognition and retention. Given the importance of intraoperative learning, we investigated question delivery in the operating room.MethodsA total of 12 laparoscopic cholecystectomies were observed and recorded. All questions were transcribed and classified using Bloom's Taxonomy, a framework associated with hierarchical levels of learning outcomes. Wait time between question end and response was recorded.ResultsSix faculty attendings and seven house officers at our institution were observed. A total of 133 questions were recorded with an average number of questions per case of 11.2. The majority of questions 112 out of 133 (84%) were classified as Bloom's levels 1–3, with only 6% of questions of the highest level. The wait time before the resident answered the question averaged 1.75 s, with attendings interceding after 2.50 s. Question complexity and wait time did not vary based on resident postgraduate year level suggesting limited tailoring of question to learner.ConclusionsIntraoperative questioning is not aligned with higher level thinking. The majority of questions were Bloom's level 3 or below, limiting the complexity of answer formulation. Most responses were given within 2 s, hindering opportunity to pursue higher‐order thinking. This suggests including higher level questions and tailoring questions to learner level may improve retention and maximize gains. In addition, with attendings answering 20% of their own questions, increasing their wait time offers another area for teaching development.

Authors: Wells Cameron I. , Robertson Jason P. , Campbell Sandra , Al‐Herz Fadhel , Rhind Bruce , Young Mike 
Published: June 2017

BackgroundPost‐operative atrial fibrillation (AF) is a common complication of oesophagectomy and thought to signal a complicated post‐operative course. AF is associated with prolonged admissions, increased healthcare costs and inpatient mortality. However, the impact of post‐operative AF on long‐term outcomes remains uncertain.MethodsPatients undergoing open Ivor‐Lewis oesophagectomy from 1994 to 2014 at Palmerston North Hospital, New Zealand, were retrospectively evaluated. Demographic, perioperative and tumour variables were collected. Regression models were used to identify independent predictors of AF and assess post‐discharge survival following oesophagectomy.ResultsIn total, 89 patients were included. New‐onset AF developed post‐operatively in 27 patients (30%). Median follow‐up was 6.3 years. Logistic regression identified volume of intravenous fluid in the first 24 h post‐operatively as a predictor of AF. Post‐discharge survival was predicted by AF occurrence (hazard ratio (HR): 2.99, 95% confidence interval (CI): 1.37–6.53, P = 0.006), preoperative chemoradiotherapy (HR: 0.43, 95% CI: 0.20–0.91, P = 0.03), 1–4 positive lymph nodes (HR: 2.29, 95% CI: 1.06–4.96, P = 0.04), ≥5 positive nodes (HR: 2.95, 95% CI: 1.25–6.94, P = 0.01) and year of operation from 2008 to 2014 (HR: 0.30, 95% CI: 0.12–0.75, P = 0.01).ConclusionPost‐operative AF was associated with poorer long‐term survival following oesophagectomy in this cohort. Further research should evaluate the influence of AF on cardiovascular and oncological outcomes following oesophagectomy.
Modeling corrosion trends in tin‐free steel and tinplate cans containing tomato paste via adaptive‐network‐based fuzzy inference system
Authors: Ganjeh Mohammad , Jafari Seid Mahdi , Amanjani Morad , Katouzian Iman 
Published: June 2017

AbstractCorrosion process in metallic cans is one of the most significant issues, which is of utmost importance in food packaging; meanwhile, it can be studied through both economical and hygienic aspects. Designing a method to determine this process in an acidic food like tomato paste might be a good standard to monitor this phenomenon in food products. Accordingly, in this article, tin‐free steel (TFS) and tinplate (TIN) cans containing tomato paste were incubated at three different temperatures (25, 35, and 45 °C) and three filling percentages (85, 90, and 95%). Corrosion rate was then studied via image processing method within six months, thereupon corrosion modeling was carried out using adaptive‐network‐based fuzzy inference system (ANFIS). Time, temperature and filling percentage were considered as the input parameters, on the other hand the corrosion rate was assumed as the output. Multiple training cycles and various membership functions were used in the form of trial and error to have the models optimized. Having the models been examined, trapezoidal membership functions with 3–3–3 functions for TFS cans and 2–2–2 functions in Tin cans were determined as the best models. High coefficients of determination (R2 = 0.97) between experimental and predicted values by optimum models presented a robust method for monitoring corrosion in metallic cans.Practical applicationsFood products might be preserved in metallic cans for more than 2 years without any significant changes in organoleptic properties. One disadvantage is that cans are more susceptible to corrosion compared with other packaging materials. The absence of appropriate methods and the high costs of analytical instruments are major problems encountered in evaluating the corrosion process. On the other hand, developing straightforward and modern techniques may be an efficient solution in this area. This study was devoted to the prediction of the corrosion process using two prevalent can plates employed in the food industry. ANFIS modeling was implemented in tomato paste, which exhibits acidic and corrosive behavior. ANFIS modeling may be an onset for further research in this area to engineer and manufacture intelligent sensors by which on‐line monitoring in complex and nonlinear interactions is undertaken.

Published: June 2017

AbstractThe effect of β‐glucan (BG) and phytosterols (PS) as fat replacers on textural, microstructural, and lubrication properties of reduced‐fat cream cheese was investigated. Five formulations (BG–PS ester, PS ester, BG–PS emulsions, PS emulsions, and BG) of cream cheese with added β‐glucan and phytosterols (in emulsified and esterified form) were investigated and compared with commercial cheese. Among the five formulations used in this experiment, the effect of β‐glucan appeared to be more pronounced imparting increased viscosity and firmness to reduced‐fat cream cheese, similar to commercial high‐fat cream cheese sample. Conversely, in lubrication study both the phytosterols (esterified and emulsified) were effective in reducing the coefficient of friction resulting in a more spreadable cream cheese. The microstructure of cream cheese with added β‐glucan and phytosterols, used solo or in combination, exhibited more open structure of casein matrix, although differences in fat globule size were observed. Cream cheese made from PS emulsion (emulsified from phytosterols powder) resulted in a larger fat globule size than PS ester and β‐glucan as shown by confocal laser scanning microscopy. In addition, the particle size distribution of cream cheese formulation containing β‐glucan only showed a monomodal curves with small globule size, while a bimodal distribution with larger particle size was observed from cream cheese with phytosterols alone.Practical applicationsReducing the fat content, impacts the quality characteristics of low‐fat cream cheese. This research showed a novel way to incorporate β‐glucan and phytosterols as fat replacers and functional ingredients in cream cheese formulation that improves its textural and lubrication properties. In addition, this article discusses the effect of β‐glucan and phytosterols used both individually and in combination on the particle size, microstructural and rheological characteristics of functional cream cheese and compares them against commercial product. The potential use of β‐glucan and phytosterols as fat replacers in low‐fat cream cheese will be useful for the industries to develop functional cream cheese that meets consumers demand.
Picking cherries or lemons: A unified theory of cross‐border mergers and acquisitions
Authors: Luong Tuan Anh 
Published: June 2017

AbstractThis article provides a theoretical framework that enhances understanding of empirical evidence suggesting that international mergers and acquisitions, a key source of foreign direct investment, seemingly target in‐country firms that are at the extremes of the productivity spectrum—either high‐productivity firms, so‐called cherries, or low‐productivity firms, the “lemons.” The framework demonstrates that foreign firms with intermediate inputs seek high‐productivity domestic firms, while foreign firms with managerial expertise seek low‐productivity domestic firms. We also show that because of the difference in available outside options, high‐productivity domestic firms can demand a significantly higher portion of profits in the partnership than low‐productivity domestic firms.

ABSTRACTThe host immune response affects pathogen virulence inClostridium difficileinfection (CDI). Thus, cytokine responses to CDI likely are associated with disease initiation and progression. Understanding the molecular drivers of inflammation and biochemical markers of disease severity is important for developing novel therapies and predicting disease prognosis. In this study, we investigated cytokine production in patients with CDI and evaluated the potential of cytokines to serve as biomarkers for CDI and predictors of disease severity. The systemic cytokine profiles of 36 CDI patients (20 with severe disease) and 8 healthy donors and the toxin-induced cytokine profiles of peripheral blood mononuclear cells (PBMC) were determined. Further, we evaluated glucosyltransferase (GT) activity in regulation of toxin-induced cytokine expression. We found upregulation of the majority of measured cytokines (11/20, 55%) in CDI patients. Interleukin-1β (IL-1β), IL-6, IL-8, IL-17A, and IL-16 were the most upregulated. High serum levels of IL-2 and IL-15 were associated with a poor prognosis in CDI patients, whereas high levels of IL-5 and gamma interferon (IFN-γ) were associated with less severe disease. Both TcdA and TcdB were potent inducers of cytokine responses, as demonstrated by stimulation of a greater number and amount of cytokines. In addition to confirming prior reports on the role of IL-8, IL-1β, and IL-6 in CDI, our data suggest that IL-16 and IL-17A, as well as the IL-1β/Th17 axis, play a key role in driving inflammatory responses in CDI. A functional GT domain ofC. difficiletoxins was required for the induction of a majority of cytokines investigated.
