Model updating of finite element model using optimisation routine
Authors: Prananta Bimo , Kanakis Toni , Vankan Jos , van Houten Rien 
Published: October 2016

Purpose
The present paper aims to describe the model updating of a small aircraft dynamic finite element model (FEM) to improve its agreement with ground vibration test (GVT) data.

Design/methodology/approach
An automatic updating method using an optimization procedure is carried out. Instead of using dedicated updating tools, the procedure is implemented using standard MSC/NASTRAN because of wide availability of the software in small aircraft industries. The objective function is defined to minimize the differences in the natural frequency and the differences in the mode shape between the analytical model and the GVT data. Provision has been made to include the quantification of confidence in both the GVT data and in the initial model. Parameter grouping is carried out to reduce the number of design parameters during the optimization process.

Findings
The optimization module of standard finite element (FE) software can be effectively used to reduce the differences between the GVT and the FEM in terms of frequency and mode shape satisfactorily. The strategy to define the objective function based on minimizing the mode shape error can reduce the improvement in the frequency error. The required user interference can be kept low.

Originality/value
The most important contribution of the present paper concerns the combination of strategies to define the objective function and selection of the parameters.
Implicit CFD methods for transitional shock wave – boundary layer interaction
Authors: Zografakis George , Barakos George 
Published: October 2016

Purpose
This paper aims to explore the potential of transition prediction methods for modelling transitional shock wave/boundary layer interactions. The study is fuelled by the strong interest of researchers and airframe manufacturers in reducing the drag of vehicles flying at transonic speeds. The principle of drag reduction via flow laminarity is valid, provided there is no need for the flow to sustain large pressure gradients or shocks. This is true, as laminar boundary layers are less resistant to flow separation.

Design/methodology/approach
It is, therefore, worthwhile to assess the performance of CFD methods in modelling laminar boundary layers that can be tripped to turbulent just before an interaction with a shock. In this work, the CFD solver of Liverpool University is used. The method is strongly implicit, and, for this reason, the implementation of intermittency-based models requires special attention. The Navier–Stokes equations, the transport equations of the kinetic energy of turbulence and the turbulent frequency are inverted at the same time as the transport equations for the flow intermittency and the momentum thickness Reynolds number.

Findings
The result is stable and robust convergence even for complex three-dimensional flow cases. The method is demonstrated for the flow around the V2C section of the TFAST EU, F7 project. The results suggest that the intermittency-based model captures the fundamental physics of the interaction, but verification and validation are needed to ensure that accurate results can be obtained. For this reason, comparisons with the TFAST experiments is put forward as a means of establishing confidence in the transition prediction tools used for shock/boundary layer interaction simulation.

Research limitations/implications
At the moment, experimental data for transonic transitional buffet are not yet available, although this will change in the near future.

Practical implications
The required CPU time is neither insignificant not prohibitive for routine computations.

Social implications
Reducing aircraft drag without compromising on stall characteristics will result in lower fuel consumption and contribute to a greener and more economic flight for passengers.

Originality/value
To the authors’ knowledge, this is the first time that transitional buffet has been addressed.
“Don’t buy this jacket”
Authors: Hwang Chanmi , Lee Youngji , Diddi Sonali , Karpova Elena 
Published: October 2016

Purpose
The purpose of this paper is to examine the effects of anti-consumption advertisement on consumers’ attitudes and purchase intentions (PIs) of an apparel product.

Design/methodology/approach
An experiment was conducted with a sample of college students (n=1,300) who were randomly assigned to view either a traditional advertisement for a Patagonia jacket or an anti-consumption advertisement of the same jacket. After that, consumer attitudes toward buying the jacket and PIs were measured employing online survey. In addition, consumer environmental concern (EC), perceived intrinsic brand motivation and extrinsic brand motivation (PIBM and PEBM) were measured to test a proposed research model.

Findings
Participants exposed to the anti-consumption advertisement reported less positive attitudes toward and lower PIs to buy the jacket than participants who viewed the traditional advertisement. Participants’ EC, PIBMs and PEBMs were found to be important predictors of the attitude and PI.

Research limitations/implications
This study provides a foundation for future research on consumer attitudes and PIs in the context of anti-consumption behavior and the effects of anti-consumption advertisement. Limitations of the present study include convenience sampling.

Practical implications
Anti-consumption advertising might be used effectively to raise consumers’ awareness on their spending habits on clothing and reduce the clutter of consuming culture.

Originality/value
The research findings contribute to the corporate social responsibility literature in the apparel context, specifically socially responsible marketing, by focusing on the nascent topic of anti-consumption. This was the first study that examined how anti-consumption advertisement might affect consumer attitudes toward buying products displayed in this advertisement.
Antecedents to internet use to collaboratively consume apparel
Authors: Johnson Kim K.P. , Mun Jung Mee , Chae Yoori 
Published: October 2016

Purpose
The purpose of this paper is to investigate attitude, subjective norm, perceived integrity of participants, materialism, and previous experience with collaborative consumption (CC) offline as antecedents to the CC of apparel facilitated by the internet.

Design/methodology/approach
Survey research with convenience sample of consumers from within the USA.

Findings
Attitude toward CC of apparel was significantly related to intention to collaboratively consume apparel online as was subjective norms. Previous experience with CC of apparel offline was significantly related to both attitude and behavioral intention. Perceived integrity of CC participants was related to previous experience with CC of apparel offline and attitude. Materialism was significantly and negatively related to previous experience with CC of apparel.

Research limitations/implications
Research limitations include the use of a convenience sample of consumers and the research was limited to one form of CC.

Practical implications
As a means to foster sustainable consumption, for those interested in promoting CC, consideration should be given to having existing participants of CC invite other family members and friends to try it as this might be more effective than targeting random members of the consuming public.

Originality/value
An investigation of CC of a fashion item (apparel) that identifies predictors to participation.
The academic conceptualisation of ethical clothing
Authors: Reimers Vaughan , Magnuson Bryce , Chao Fred 
Published: October 2016

Purpose
Despite supposed widespread consumer support for ethical clothing, it still often fails to translate into actual purchase. The purpose of this paper is to determine whether the way in which academics have defined and measured ethical clothing could account for this.

Design/methodology/approach
An over reliance on convenience sampling and the use of student samples has also been touted as a possible reason for this attitude-behaviour gap. To address this, this study employed a consumer household sample. It also used a quantitative survey approach to collect its data and structural equation modelling to analyse it.

Findings
In contrast to the way in which academics have conceptualised the construct, consumer perceptions of ethical clothing were found to be influenced by four dimensions: environmental responsibility, employee welfare, animal welfare and slow fashion attributes.

Originality/value
Ethical clothing has typically been operationalised using just two of these four dimensions. Ironically, one of the two dimensions often overlooked by academics – animal welfare – had the strongest influence on consumer perceptions. Previous academic efforts had never employed more than three dimensions, and yet the results of this study suggest that all four must be present if an item of clothing is to be regarded as “ethical”.

Authors: Poghosyan Lusine , Lucero Robert J. , Knutson Ashley R. , W. Friedberg Mark , Poghosyan Hermine 
Published: October 2016

PurposeThe purpose of this paper is to synthesize existing evidence regarding health care team networks, including their formation and association with outcomes in various health care settings.Design/methodology/approachNetwork theory informed this review. A literature search was conducted in major databases for studies that used social network analysis methods to study health care teams in the USA between 2000 and 2014. Retrieved studies were reviewed against inclusion and exclusion criteria.FindingsOverall, 25 studies were included in this review. Results demonstrated that health care team members form professional (e.g. consultation) and personal (e.g. friendship) networks. Network formation can be influenced by team member characteristics (i.e. demographics and professional affiliations) as well as by contextual factors (i.e. providers sharing patient populations and physical proximity to colleagues). These networks can affect team member practice such as adoption of a new medication. Network structures can also impact patient and organizational outcomes, including occurrence of adverse events and deficiencies in health care delivery.Practical implicationsAdministrators and policy makers can use knowledge of health care networks to leverage relational structures in teams and tailor interventions that facilitate information exchange, promote collaboration, increase diffusion of evidence-based practices, and potentially improve individual and team performance as well as patient care and outcomes.Originality/valueMost health services research studies have investigated health care team composition and functioning using traditional social science methodologies, which fail to capture relational structures within teams. Thus, this review is original in terms of focusing on dynamic relationships among team members.
“Through the looking glass: envisioning new library technologies” Drones
Authors: Fernandez Peter 
Published: October 2016

Purpose
The word “drone” is the common term for an unmanned aerial vehicle – a robot that combines flight with sensors (usually cameras) to allow for unprecedented freedom in observing and interacting with the world.

Design/methodology/approach
This column will explore the technology that makes modern drones possible, what makes drones useful and the role of libraries in making drones accessible to their patrons, now and in the future.

Findings
Many of these applications are equally appealing to hobbyists and professionals. For some small-scale gardeners, drones can be used to scare away pests, such as deer, or take aerial photographs that provide a new perspective of their garden.

Originality/value
For the agriculture industry, drones already account for $864.4 million in spending per year and are expected to grow to account for over $4 billion by 2022, as they are used not only to monitor and plan crops but also to plant seeds and provide accurate pesticide control (Wood, 2016).
Linking transformational leadership, creativity, innovation, and innovation-supportive climate
Authors: Khalili Ashkan 
Published: October 2016

PurposeThe significance of creativity and innovation within organisations has been shown on several occasions. The purpose of this paper is to investigate the association between transformational leadership and employees’ creativity and innovation. Additionally, this study explored the moderating role of employees’ perceptions of a supportive climate for innovation.Design/methodology/approachData were collected from 1,172 employees who were working in various types of industries in Iran, a developing country.FindingsThe results of this study revealed positive and significant relationships between transformational leadership and employees’ creativity and innovation. Also, the findings indicated employees’ perceptions of a supportive climate for innovation moderated the transformational leadership‐employees’ creativity and transformational leadership‐employees’ innovation relationships.Practical implicationsOrganisations should invest in transformational leadership training and in the selection of leaders with this leadership style if their aim is to foster and enhance employees’ creativity and innovation. They also should invest in organisational climate improvement in order to provide a dynamic platform for being creative and innovative in the workplace.Originality/valueThis study is one of the first to investigate the following relationships in a developing country, Iran: the associations between transformational leadership and employees’ sense of creativity and innovation and the moderating impact of employees’ perceptions of a supportive climate for innovation.
Integrating lean and green management
Authors: Hallam Cory , Contreras Carolina 
Published: October 2016

PurposeThe purpose of this paper is to perform a literature review of peer-reviewed journal articles investigating the relationship between Lean and Green management in light of developing an integrated management model.Design/methodology/approachAfter an extensive search, 60 articles from 1996 to 2016 were identified as relevant to this study.FindingsThe evidence of successful integration of Lean and Green management has largely been weak. The strongest positive evidence between the two management philosophies has been for Lean implementation pushing Green outcomes through operational waste reduction, thus improving environmental performance. The majority of studies suggest highly optimistic outcomes from integrating Lean and Green, however, an integrated operating model of the firm relating Lean and Green is lacking.Research limitations/implicationsThe literature review suggests the necessary elements for proposing an integrated operating model of the firm.Practical implicationsThe paper offers interesting implications for managers. While most Lean implementations have resulted in some positive environmental outcomes, both management philosophies tend to be implemented independently. Integrating the implementation of Lean and Green offers the potential for synergistic returns.Originality/valueThe findings are derived from a systematic literature review of articles that have studied the relation between Lean and Green management, resulting in a proposed integrated model of firm performance.
Modeling unpredictable failures of 304 construction material in seawater by pitting corrosion and simulate chloride ion distribution by finite element method
Authors: Paul Subir 
Published: October 2016

PurposeThe purpose of this paper is to predict the life of a corroding metallic structure in seawater so that uncertain and unpredictable failures of a structure, leading to accidents, can be prevented.Design/methodology/approachPitting has been known to show a large scatter in the measurable parameters such as corrosion rate, maximum pit depth, time to perforation and so on. Scatter results from the influence on pit development on metal surface heterogeneity and from variations in the corrosive environment over time. All these facts suggest that randomness is an inherent and unavoidable characteristic of pitting corrosion over time, so that stochastic models have been developed to formulate pit depth as a function of parameters influencing the process. Since chloride penetrates the passive film of the metal surface, Cl ion distribution into the metal has been mapped by finite element method (FEM).FindingsThe maximum pit depth which decides the onset of perforation or leakage has been modeled by the following equation:d=36.31(ΔE)0.68×(Δt)0.35. Cl ion distribution within a pit and outside has been modeled for better understanding of pit initiation which till today is not fully understood.Practical implicationsPerforation and leakage of a tank, container, or pipeline occur when the depth of pitting reaches the section thickness of the material of which the metallic structures are made. The pitting corrosion is localized and occurs at any spot or site where electrochemical conditions (ΔE Equation (9)) are prone to pitting. This leads to unpredictable failures of the structures which may look polished and undamaged under naked eyes. In most metallic structures, pitting may be present at some spots, but failures occur only when the depth predicted by the model Equation (9) reaches the section thickness of the material. Thus, determining pipe to soil potential gives a guide to go for maintenance before pit depth reaches the material thickness, and thereby unpredictable failure can be prevented. Second, the map generated by FEM showing Cl distribution throws much information and light on movement of Cl ions from passive layer into the pit, which leads to its growth. This helps scientists and researchers to understand the mechanism and gives much insights on finding new methods for protection of structures.Social implicationsThe work will guide the engineers and researchers to prevent unpredictable failures of structures leading to accidents and human and property loss and prevent environment pollution from spilling of oil from tank and pipeline.Originality/valueThis is an original work based on several laboratory-generated simulated experimental data.
Traditional forest management practices stop forest succession and bring back rare plant species
Authors: Douda Jan , Boublík Karel , Doudová Jana , Kyncl Michal 
Published: October 2016

Summary

Past management practices may continue to influence ecosystem functions and processes for decades, centuries or even longer after they have been abandoned. Until now, few researchers have attempted experiments which test the effects of restoring some of these past management practices on long‐term community developmental trajectories.

Strong evidence indicates that the diversity of various taxonomic groups declined in European lowland forests in the second half of the 20th century, following the abandonment of some traditional forest management practices. We carried out a five‐year field trial in a lowland thermophilous oak forest to describe the effects of restoration of litter raking and grass cutting on the long‐term developmental trajectory of species composition and the diversity of understorey vegetation. We used target species groups, that is species specific to thermophilous forests and dry grassland vegetation and plant functional traits to evaluate the restoration success using both compositional and functional outcomes.

Dissimilarity in species composition between the managed plots and controls increased significantly during the 5 years of the trial. Litter raking increased the richness and cover of the thermophilous forest and dry grassland species, whereas grass cutting increased the richness and cover of only the dry grassland species. We did not record any overall trends in divergence of functional trait composition between managed and control plots. In the litter raking plots, we recorded increases in community‐weighted means of specific leaf area, in lateral spread and in Ellenberg indicator values for nutrients and soil reaction. In contrast, we found little evidence for predictability of species functional trait composition subjected to grass cutting.

Synthesis and applications. Following the restoration of traditional forest management practices, we were able to change the community's developmental trajectory towards higher richness and cover of target species. The evaluation of community developmental trajectories using species and functional trait composition supports the idea that restoration of traditional forest management practices should carefully distinguish among possible interventions.

SummaryMelatonin has a beneficial role in adult rat models of multiple sclerosis (MS). In this study, melatonin treatment (10 mg/kg/d) was investigated in young age (5‐6 weeks old) Lewis rat model of acute experimental autoimmune encephalomyelitis (EAE) followed by assessing serum levels of lactate and melatonin. Results showed that clinical outcomes were exacerbated in melatonin‐ (neurological score = 6) vs PBS‐treated EAE rats (score = 5). Melatonin caused a significant increase in serum IFN‐γ, in comparison to PBS‐treated EAE rats whereas no considerable change in IL‐4 levels were found, although they were significantly lower than those of controls. The ratio of IFN‐γ/IL‐4, an indicator of Th‐1/Th‐2, was significantly higher in PBS‐ and melatonin‐ treated EAE rats, in comparison to controls. Moreover, results showed increased lymphocyte infiltration, activated astrocytes (GFAP+ cells) but also higher demyelinated plaques (MBP‐deficient areas) in the lumbar spinal cord of melatonin‐treated EAE rats. Finally, serum levels of lactate, but not melatonin, significantly increased in the melatonin group, compared to untreated EAE and normal rats. In conclusion, our results indicated a relationship between age and the development of EAE since a negative impact was found for melatonin on EAE recovery of young rats by enhancing IFN‐γ, the ratio of Th1/Th2 cells, and astrocyte activation, which seems to delay the remyelination process. While melatonin levels decline in MS patients, lactate might be a potential diagnostic biomarker for prediction of disease progression. Early administration of melatonin in the acute phase of MS might be harmful and needs further investigations.
