How to prepare and deliver a good presentation: general principles for success
Authors: Stonehouse David 
Published: August 2018

The author has more than 14 years' experience in higher education, supporting students in delivering presentations for assessment and in marking across all levels up to masters, and as an external examiner. This article examines and highlights the general principles that will assist the student in writing, preparing and delivering a successful presentation. Standing up in front of your peers, tutors, or interviewers can be one of the most stressful things students and job applicants face. The aim of this article is to give advice and encouragement to the student, thereby hopefully reducing some of the stress that presentations cause. Areas such as the length of the presentation, structure and content, maintaining confidentiality, referencing, presentation marking criteria, spelling and grammar, font size and clutter, animation and colour, individual or group presentations, poster presentations, preparing for questions, audience participation, notes and handouts, confidence and body language, and feedback will be discussed.
Designing a sustainable future through fashion education
Authors: Radclyffe-Thomas Natascha 
Published: August 2018

Abstract
With production moving offshore in the race to the bottom, necessary to satisfy increased demand for more garments and faster trends delivered at lower prices, fashion in the developed world has become not just fast, but disposable. One of the ‘successes’ of the twentieth-century fashion industry was to democratize fashion; by adopting mass production techniques and sourcing from low-wage economies, fashion retailers were able to produce runway looks at more affordable prices. Concurrently, developments in fashion media sped up the communication of fashion and we have seen an exponential proliferation of enticing creative imagery circulating from brands, models, online influencers and passionate amateurs. Consequently, rates of fashion consumption have risen, unacceptable working conditions continue for many, and the fashion industry is facing complex and demanding challenges including resources, climate change, waste, labour conditions and income inequality. Much as we now understand how garment design has an exponential impact on a garment’s sustainability, and recognize that incorporating sustainable design principles is paramount, so those of us in fashion education should prioritize sustainability in our curriculum design and increasingly, I have felt a responsibility to bring these issues into the classroom, to design a fashion education that acknowledges and addresses ethical and sustainable aspects of fashion.
Predicting consumer intention to purchase clothing products made from sustainable fabrics: Implications for the fast-fashion industry
Authors: Yoo Jeong-Ju , Divita Lorynn , Kim Hye-Young 
Published: August 2018

Abstract
The goal of this study is to investigate the differential influences of environmental concern and fashion opinion leadership on consumer intention to purchase clothing products made from sustainable fabrics. In doing so, this study examines the mediating role of environmental attitude towards clothing consumption. The data were collected from 122 US college students with an average age of 21.4. The majority of the participants were female (83.6 per cent) and Caucasian (64.5 per cent). A weighted least squares (WLS) hierarchical regression analysis was used for the data analysis. The results suggested that fashion opinion leadership was a more powerful determinant than environmental concern in predicting consumer intention to purchase clothing products made from sustainable fabrics. However, environmental attitude towards clothing consumption did not serve as a significant mediator. These findings provide beneficial insight for fast-fashion retailers mainly targeting fashion opinion leaders. Managerial implications are discussed to delineate how fast-fashion retailers can benefit from sustainable production and retailing strategies.
Re-fashioning the garment industry: Exploring innovations for a circular economy
Authors: Hussain Talia 
Published: August 2018

Abstract
The circular economy is promoted as an innovation and growth model for a garment industry widely understood to be wasteful, polluting and ripe for change. There is a growing body of knowledge related to sustainability, design, eco-innovation and business; there is, however, a scarcity of material that examines all subjects as they relate to the garment industry. There exists, in both literature and practice, a conceptual gap between the commercial viewpoint and established thinking around sustainable practices. There is a lack of research investigating operations management, buying and merchandising roles in apparel product development. Understanding the influence of these functional roles is crucial in developing strategies for closing the gap between commercial and environmentally sustainable practices and bringing innovations to market. Investment in sustainability-related knowledge and capabilities within firms is needed. Reconsidering the role of fashion designers, expanding their training and elevating them to process-leading problem-solvers could unlock new sources of value within the industry.
Ebola: History and some implications for Africa
Authors: Pavlik Ivo , Lategan François , Verter Nahanga 
Published: August 2018

Abstract
The Ebola disease derives its name after a small river, the Ebola River, flowing through the former Zaire (present day DR Congo) and was formally named in 1976. The disease belongs to the category of diseases referred to as “haemorrhagic fever”; the causal agent – a filovirus (from Latin “filo” = thread) belonging to the Filoviridae family. The treatment of Ebola has been only symptomatic, i.e. based on mitigation of the symptoms related to the infection, such as kidneys and liver. An effective vaccine has not been developed yet, even though rigorous attempts have been made and reported. Ebola has been primarily found in the Ivory Coast, DR Congo, Sudan, Gabon and other equatorial African countries. Based on the data obtained during the latest epidemics, people are strongly advised to avoid direct contact with patients, avoid buying bush meat in street markets and not handle dead bats, megabats, monkeys or gorillas. Estimated data suggest that more than 5,000 of these animals have died. The disease was also diagnosed in patients in the USA and Europe. The epidemic afflicted West Africa and had significant implication on their economy in terms of lost production, higher fiscal deficits, rising prices and lower real household incomes, leading to greater poverty.

Published: August 2018

Abstract
Various health challenges and fatalities in rural communities of most developing countries of the world have been traceable to the unabated use of biomass energy sources. We therefore assessed the awareness of the health implications of the use of biomass energy sources among women in rural households of Jigawa State. Multistage sampling procedure was used to collect data from 120 respondents using structured questionnaires. Data were collected on respondents’ socioeconomic characteristics, types of biomass used, information sources on the health implications from use of biomass energy sources, awareness of the health implications and constraints to the use of alternatives to biomass. Data were summarised using frequencies, percentages, means, Chi-square and Pearson Product Moment Correlation. Majority of the respondents (78.3 %) were below 40 years of age with a mean age of 30 ± 2.02 years. Majority were married (90.8 %), Muslims (100 %), involved in agro-processing (65.8 %), had no formal education (73.3 %), and earned not more than ₦10, 000 (90.8 %) with mean household size of 9 members. Wood (100 %) and charcoal (100 %) were the dominant biomass energy sources used. Respondents’ main source of information on the health implications of the use of biomass were radio (64.2 %) and extension agents (54.2 %). Awareness level of the health implications from the use of biomass energy sources was fairly high (51.7 %). High cost of the alternatives, scarcity of refilling points and alternatives and lack of capital were the main hindrances to the use of the alternatives to biomass energy sources. The result on the inferential statistics revealed that a significant association existed between education (χ2 = 6.08; P < 0.05) and awareness of health implications from the use of biomass. Efforts should be made to sensitize women on the health implications resulting from the use of biomass. Alternatives should be made available and affordable to encourage a switch from biomass energy sources thereby reducing the fatalities that may result from its continual use.
Recheneffiziente Bewertung von Messsignalen am Beispiel einer Regelkreisüberwachung für mechatronische Antriebssysteme
Authors: Krippner Wolfgang , Kisner Viktor , Listmann Kim D. , Konigorski Ulrich 
Published: August 2018

Zusammenfassung
Die Regelkreisüberwachung findet für mechatronische Antriebssysteme nur selten Anwendung, da hierfür oftmals zusätzliche, kostspielige Hardware benötigt wird. Im Rahmen dieses Beitrags wird gezeigt, wie mit der Autokorrelationsfunktion Messsignale aus Regelkreisen für mechatronische Antriebssysteme nach auftretenden Oszillationen im Zeitbereich bewertet werden können. Die Analyse der Oszillation nach der Frequenz und eine Abschätzung des Signal-Rausch-Verhältnisses sind möglich. Um auch eine recheneffiziente Auswertung zu erreichen, wird über die Information, welche während der Berechnung von endlichen, zeitdiskreten, homogenen Markovmodellen entsteht, ein Schätzverfahren für die Autokorrelationsfunktion entwickelt. Es resultiert ein Verfahren für die Bewertung von Oszillationen in Messsignalen, welches nahezu frei von Parametern und robust gegenüber der Parameterwahl ist. Durch die geringen notwendigen Rechenkosten kann es auf rechenleistungsschwacher Hardware, wie speicherprogrammierbare Steuerungen, implementiert werden.
On steady-state disturbance compensability for actuator placement in adaptive structures
Authors: Wagner Julia Laura , Gade Jan , Heidingsfeld Michael , Geiger Florian , von Scheven Malte , Böhm Michael , Bischoff Manfred , Sawodny Oliver 
Published: August 2018

Abstract
Adaptive structures in civil engineering are mechanical structures with the ability to modify their response to external loads. Actuators strongly affect a structure’s adaptivity and have to be placed thoughtfully in the design process to effectively compensate external loads. For constant loads, this property is introduced as steady-state disturbance compensability. This property can be linked to concepts from structural engineering such as redundancy or statical indeterminacy, thus representing an interdisciplinary approach. Based on the disturbance compensability matrix, a scalar performance metric is derived as quantitative measure of a structure’s ability to compensate the output error for arbitrary constant disturbances with a given set of actuators. By minimizing this metric, an actuator configuration is determined. The concept is applied to an example of a truss structure.
Multivariate statistical approaches for an early detection of foaming in a refinery SCOT unit
Authors: Al Mawla Hassan Enam , Kroll Andreas 
Published: August 2018

Abstract
The formation of foam in amine units is an issue that plant operators and field personnel are confronted with on a regular basis. The inability to take proper actions in due time may result in plant downtime and increased emissions. Steep rises in differential pressure indicate foam formation, and are monitored manually in practice. Antifoaming agent is added in order to reduce foaming, but this is usually carried out under time pressure. Hence, plant operating authorities have expressed a strong interest in a data-driven solution capable of providing an early warning against foaming. The classical univariate alarm associated with differential pressure can be ineffective for foaming detection due to high misdetection rates and its lateness of detection. Modern univariate approaches based on pattern recognition techniques may not be suitable either for an early detection, as no universally distinctive features of differential pressure are observed prior to foaming in the present study. In this contribution, the multivariate statistical process monitoring approach based on principal component analysis (PCA) is applied to the early detection of foaming in a continuously operated Shell Claus Off-gas Treating (SCOT) unit of a major refinery in Germany. The results are extended to facilitate fully automated and adaptive modeling based on exponentially weighted recursive principal component analysis (EWRPCA).
Enhancement of Damage Detectability in Aircraft Structures Using the Fusion of NDT Results
Authors: Zapłotny Marcin , Katunin Andrzej , Dragan Krzysztof 
Published: August 2018

Abstract
Following the damage tolerance philosophy in aircraft design and operation, one of the most significant stages of maintenance is non-destructive testing of structures. It is, therefore, essential to use testing methods sensitive to particular damage types occurring in aircraft structures during operation. In this paper, the authors present a study on selection and comparison of methods of information fusion applied to testing the results of inspection of composite structures used in aircraft elements, obtained using various ultrasonic methods. The presented approach of fusion of ultrasonic scans allows for enhancement of damage detection and identification due to the presence of different parts of information about detected damage obtained from different initial information sources in a single resulting set. Such an approach can be helpful at the decision-making stage during inspection of aircraft elements and structures. Besides the methodology, the GUI-based software for performing fusion of various types of ultrasonic data is presented.
A Model for Fatigue Crack Growth in the Paris Regime under the Variability of Cyclic Hardening and Elastic Properties
Authors: Kebir Tayeb , Benguediab Mohamed , Imad Abdellatif 
Published: August 2018

Abstract
Over the last 60 years, several models have been developed governing different zones of fatigue crack growth from the threshold zone to final failure. The best known model is the Paris law and a number of its based on mechanical, metallurgical and loading parameters governing the propagation of cracks. This paper presents an analytical model developed to predict the fatigue crack propagation rate in the Paris regime, for different material properties, yield strength (σy), Young’s modulus (E) and cyclic hardening parameters (K’, n’) and their influence by variability. The cyclic plastic deformation at a crack tip or any other cyclic hardening rule may be used to reach this objective, for to investigate this influence, these properties of the model are calibrated using available experimental data in the literature. This FCGR model was validated on Al-alloys specimens under constant amplitude load and shows good agreement with the experimental results.
Google Trends and Structural Exchange Rate Models for Turkish Lira–US Dollar Exchange Rate
Authors: Bulut Levent , Dogan Can 
Published: August 2018

AbstractIn this paper, we use Google Trends data to proxy macro fundamentals that are related to two conventional structural determination of exchange rate models: purchasing power parity model and the monetary exchange rate determination model. We assess forecasting performance of Google Trends based models against random walk null on Turkish Lira–US Dollar exchange rate for the period of January 2004 to August 2015. We offer a three-step methodology for query selection for macro fundamentals in Turkey and the US. In out-of-sample forecasting, results show better performance against no-change random walk predictions for specifications both when we use Google Trends data as the only exchange rate predictor or augment it with exchange rate fundamentals. We also find that Google Trends data has limited predictive power when used in year-on-year growth rate format.
Quantifying International Tax Avoidance: A Review of the Academic Literature
Authors: Riedel Nadine 
Published: August 2018

AbstractThis paper provides a brief review of the academic literature that assesses the quantitative importance of tax avoidance behaviour of multinational entities (MNEs) by means of income shifting from high-tax to low-tax affiliates. Existing studies unanimously report evidence in line with tax-motivated profit shifting (despite using different data sources and estimation strategies). In terms of shifting channels, there is evidence consistent with strategic mispricing of intra-firm trade, the location of valuable intellectual property at low-tax affiliates and debt-shifting activities. The quantitative estimates vary across approaches and studies though. The paper moreover stresses that some care should be warranted when interpreting profit shifting estimates as they often rely on non-trivial assumptions.
The Impact of the Crisis and Unconventional Monetary Policy on European Inflation Dynamics
Authors: Schäfer Benjamin 
Published: August 2018

AbstractThis study investigates the impact of the economic crisis in the late 2000s and early 2010s on European inflation dynamics using a hybrid New-Keynesian Phillips Curve (NKPC) during three distinct periods. The pre-crisis period from 1999 through mid-2007, the crisis period until August 2012, and finally the “Whatever-It-Takes”-period after the remark by ECB president Mario Draghi. The structural hybrid NKPC is estimated for six countries of the Euro area (Germany, France, Italy, Spain, The Netherlands and Austria) and for each of the three periods. The crisis and the subsequent reaction of the ECB both seem to have had a profound impact on the dynamics, as estimated parameters differ markedly between the periods. A discussion and interpretation of the results is provided.

Factors determining failure of intertrochanteric fracture fixation with a dynamic hip screw: a retrospective analysis
Authors: Jain Ravi K. , Verma Abhineet , Jain Arjun , Patel Yogesh 
Published: August 2018

<p class="abstract"><strong>Background:</strong> The intertrochanteric fractures are extra capsular fractures of proximal femur in the trochanteric region. Different fixation techniques were tried for intertrochanteric fractures, with variety of implants but the dynamic hip screw fixation is most widely accepted treatment. However, several authors have concluded that sliding compression screws may be associated with several complications such as perforation of the femoral head, loss of reduction caused by excessive sliding of the lag screw, non-union, shortening of the affected limb and pain. This study was carried out to ascertain the factors that contributed to mechanical failure at our institute.</p><p class="abstract"><strong>Methods:</strong> We retrospectively reviewed 92 patients with unilateral intertrochanteric fracture treated with a sliding hip screw between July 2015 and April 2017. Postoperative radiographs were studied for any loss of reduction, which was defined as a varus deformity greater than 10°, perforation of the femoral head, extrusion of the lag screw of more than 20 mm, or metal failure. The Pearson chi-square test was used to assess the relationship between failure and osteoporosis. A p value of less than 0.05 was considered to be significant.<strong></strong></p><p class="abstract"><strong>Results:</strong> Results revealed a significant relationship between failure and osteoporosis. A possible relationship between the stability of the fracture on Evans’ classification and osteoporosis on Singh’s index was investigated which revealed a high positive correlation between the failure rates of unstable fractures with osteoporosis.</p><p><strong>Conclusions:</strong> An unstable fracture combined with osteoporosis, has higher percentage of fixation failure leading to other methods of treatment like hemiarthroplasty. </p>
Influence of sulfide on the evaluation of methane production through the degradation of sugarcane vinasse

Published: August 2018

Anaerobic digestion is a widely used effluent and organic waste treatment practice, in which it is possible to minimize and control environmental problems, associating the reduction of environmental impacts with energy recovery. Low methane production and process instability are often found in anaerobic digestion reactors, preventing this technique from being widely applied. Inhibitory substances, such as sulfides resulting from sulfate conversion by the sulfur reducing bacteria, are one of the causes of inhibition or malfunctioning of anaerobic digesters if they are present in the effluent to be treated. The objective of this work is to evaluate the effect of sulfide at two different values of pH (7.0 and 7.5) using sulfide concentrations of 0 to 1000 mg S2-L-1. All the tests were performed in batches and performed at mesophilic conditions. For the concentrations of 50 mg S2-L-1 and 1000 mg S2-L-1, the inhibitions of the methanogenic activity at pH 7.0 were in the order of 38.5% to 59.8% and at pH 7.5 in the order of 67% to 94%, respectively. Concerning the test at pH 7.0, the removal of COD in the experiment without addition of any concentration of S2- was 93.3%, and it reached a 49.14% COD removal at concentrations of 1000 mg S2-L-1. At pH 7.5 under the same conditions, the COD removals were respectively 80.7% and 9.6%. The concentrations of 50, 75 and 100 mg S2-L-1 of S2- initially tested at the two aforementioned pH values promoted the greatest increase in the reduction of SMA. When the experiments were carried out at pH 7.0 the reductions were 37.96%, 41.70%, and 46.06% respectively for the same concentrations. At pH 7.5 the reductions represented 67.01%, 82.47% and 81.81%. http://dx.doi.org/10.18226/23185279.v6iss2p1
