Radiation-chemically modified PP/CNT composites
Authors: Kalkis Valdis , Reinholds Ingars , Zicans Janis , Merijs-Meri Remo , Bitenieks Juris , Bockovs Ivans 
Published: June 2014

AbstractIn this work, the authors studied the effects of electron beam (EB)-induced changes in stress-strain characteristics, heat shrinkage stresses, and structure characteristics on polypropylene (PP) composites containing bisphenol-A-dimethacrylate (BPDMA) as the radiation sensitizer and different contents of multi-walled carbon nanotube (CNT) filler (0–2 wt.%). The effect of stearic acid (SA) as the surface modifier on the improvement of CNT dispersion in the PP matrix was also studied. Initially, PP blends with different contents (up to 10 wt.%) of BPDMA were prepared to determine the effective concentration of the sensitizer for the modification of the PP matrix. PP/BPDMA composites and blends filled with CNTs were irradiated up to 25–50 kGy of radiation doses. The properties of unirradiated compositions and those modified by EB, were compared. Radiation-induced changes were confirmed by gel fraction and by the changes in Fourier transform infrared spectroscopy spectra. The results showed an increase in Young’s modulus, yield strength, and thermal-relaxation stresses for the irradiated PP/CNT compositions grafted with 3 wt.% of BPDMA and compatibilized with SA.

Novel sustainable industrial processes: from idea to commercial scale implementation
Authors: Harmsen Jan 
Published: June 2014

Abstract
This article summarizes the consensus on sustainable development, shows industrial cases and provides key guidelines to transfer ideas into commercial scale processes. The triple P sustainable development concept has reached global industrial consensus and has gained importance in the making of business policies and practical implementations. Obtaining a sustainable process means then that it provides a need, is socially accepted, does no environmental harm and makes a profit. Industrial cases show that this is possible. An innovative way of obtaining sustainable solutions is by industrial symbiosis, in which very different partners such as a local government, a technology provider, a water board and a chemical company co-operate with regards to a new solution; turning a waste stream into a feed stream. Open innovation is generally a good way to obtain radical novel solutions cost-effectively. Guidelines for entering open innovation projects are provided. A technology readiness level (TRL) assessment method for process innovation with academic groups is also provided. Guidelines for effective and efficient innovation from research to commercial scale implementation, based on stage-gate innovation pathway funnel, are provided. Finally, a novel method for process concept design based on essential functions and essential inputs and outputs only, is provided.
Characteristics of hand sanitizer ingestions by adolescents reported to poison centers
Authors: Forrester Mathias B. 
Published: June 2014

Abstract
Background: There had been reports of adolescents using hand sanitizers to obtain alcohol and ending up in emergency departments with alcohol poisoning.
Objective: This study aimed to describe the pattern of adolescent ingestions of hand sanitizers reported to a statewide poison center system.
Subjects: Our study subjects included patients aged 13–19 years who reported hand sanitizer ingestions as reported to Texas poison centers during 2000–2013.
Materials and methods: The distribution of the ingestions was determined for various demographic and clinical factors.
Results: Of 385 total cases, 61% of the patients were male, and the mean age was 15.3 years. The ingestion reason was unintentional (61%), intentional abuse/misuse (18%), and malicious (10%). Ingestion site was most frequently reported to be the patient’s own residence (53%), followed by school (35%). About 77% of the patients were managed on site. The medical outcome was serious (moderate effect or unable to follow-potentially toxic) in 5% of the cases. The most frequently reported adverse clinical effects were vomiting (5%), abdominal pain (4%), nausea (4%), throat irritation (4%), and drowsiness (2%).
Conclusion: Adolescents who ingested hand sanitizers were more likely to be male and younger. One-third of the ingestions occurred at school, suggesting that school personnel might be made aware of the potential problem of hand sanitizer ingestions by adolescents. Nevertheless, despite the potential for serious outcomes from adolescent hand sanitizer ingestion, most of the ingestions reported to poison centers are not likely to be serious and can be successfully managed outside of a healthcare facility.
Empowerment and Mentoring in Nursing Academia

Published: June 2014

AbstractIn 2011, there was an expected shortage of 200 full-time faculty. While there are an estimated 322 graduate students in Nurse Practitioner and Masters/PhD programs in Canada today, the supply of potential new faculty falls short of the anticipated demand in the years ahead (Canadian Association of Schools of Nursing). This mixed method study explored how organizational culture and the perceived level of psychological and structural empowerment are associated with one’s work environment among Canadian nursing faculty and to explore the state of mentorship in schools of nursing.
The presence of minority languages in linguistic landscapes in Amsterdam and Friesland (the Netherlands)
Authors: Edelman Loulou 
Published: June 2014

AbstractThis article describes an investigation of linguistic landscapes in the Netherlands. By means of a detailed quantitative analysis, it explores the extent to which the linguistic landscape reflects the languages spoken by the speech community. The study took place in both the capital city of Amsterdam, which has many immigrants and foreign tourists, and in the province of Friesland, which is home to a Frisian-speaking minority. The main finding is that in the linguistic landscape in both field sites, Dutch and English prevail, whereas minority languages have a limited presence. Differences in the ethnolinguistic composition of Amsterdam and Friesland's populations are partly reflected in differences between the linguistic landscapes.
630 kilometres by bicycle: observations of English in urban and rural Finland
Authors: Laitinen Mikko 
Published: June 2014

AbstractThis article discusses selected observations of English usage in signage in Finland, a Nordic nation in which the significance of English has become more pronounced in recent decades. The background for this study comes from a large quantitative survey, carried out in 2007, charting the role of English in the Finnish society. One of the topic areas in this survey deals with people's encounters with English and its visibility in their daily life, and this article aims to add a qualitative angle to these results. The observations discussed here were collected in 2009 during a six-day bicycle trip from Helsinki to the regional centre of Oulu. The analysis moves from mere quantitative recording of signs to a more nuanced analysis of interpretations of their situated meanings in public spaces. These observations show that the presence of English in both urban and rural areas of the country is far from a simple phenomenon, and illustrate how charting signs in space provide valuable information on language contact situations.
Tallinn: monolingual from above and multilingual from below
Authors: Zabrodskaja Anastassia 
Published: June 2014

AbstractThis article presents a microanalysis of multilingual signs collected in Tallinn, a city composed of approximately 50% Estonian speakers and 50% Russian speakers. The data reveal that despite the official language policy promoting Estonian as the dominant language, “multilingualism from below” is widespread. The graphic representation of languages in multilingual texts sometimes involves creative forms constructed from the combination of the Estonian and Russian languages or the Latin and Cyrillic alphabets (“script-switching” or “script-mixing”). Caught between the requirements of a Language Act that promotes Estonian as the country's official language and the real-life multilingual situation, businesses try to balance the official policy and desire of Estonian-speakers with a wish to attract the attention of local Russians and tourists towards their services and goods. This ethnographic study of the Tallinn linguistic landscape is supplemented by qualitative data regarding the perceptions of Russian- and Estonian-speaking students. Individual interviews provided information about how speakers with different mother tongues and linguistic backgrounds perceive Estonian-Russian signs. Estonian students show rather negative reactions to the presence of multilingual signs and bilingual wordplay, whereas Russian-speaking students express mainly positive responses to the Russian-Estonian hybrid signs.
Sexed signs – queering the scenery
Authors: Milani Tommaso M. 
Published: June 2014

AbstractThe main argument of this article is that Linguistic Landscape (LL) scholarship has largely ignored – erased even – gender and sexuality, two important axes of power along which public spaces are structured, understood, negotiated and contested. In order to partly redress this academic oversight, this article investigates a small data set of banal sexed signs, mundane semiotic aggregates, which, precisely because of their fleeting and unassuming character, can easily be ignored, but nonetheless “(in)form our understandings and experiences of [gender,] sexuality and subjectivity” (Sullivan 2003: 190). In doing so, the article also argues for the importance of incorporating queer theory into the analytical apparatus of Linguistic Landscape research, because it provides us with a valuable theoretical lens through which to unveil the operations of power in relation to gender and sexuality (and other social categories) in public space.
Eliciting Security Requirements from the Business Processes Using Security Risk-Oriented Patterns
Authors: Matulevičius Raimundas , Ahmed Naved 
Published: June 2014

Abstract
Although importance of aligning modelling of business processes
and security is growing, there is rather limited research
performed on elicitation of security requirements from the
business processes. In this paper we discuss how security
risk-oriented patterns could help solving the above problem. Using
the illustrative example, we present a two-step method for (i)
pattern occurrence discovery in, and (ii) for security
requirements definition from the business process model. We hope
that our proposal could help elicit security requirements at the
early system development stages, however, we still need to
validate it empirically.
Privacy Analysis of User Behavior Using Alignments
Authors: Adriansyah Arya , van Dongen Boudewijn F. , Zannone Nicola 
Published: June 2014

Abstract
Privacy is becoming a urgent issue in information systems
nowadays because of the stringent requirements imposed by data
protection regulations. Traditional security approaches based on
access control and authorization are not adequate to address these
requirements. The underlying fundamental problem is that those
approaches are preventive and thus they are not able to deal with
exceptions. In this paper, we present a practical privacy
framework that shifts the problem of preventing infringements into
a problem of detecting infringements. The framework is based on
systematic log auditing, use of patterns and privacy metrics to
detect and quantify infringements.
A Case Against Taxes and Quotas on High-Skill Emigration
Authors: Clemens Michael A. 
Published: June 2014

AbstractSkilled workers have a rising tendency to emigrate from developing countries, raising fears that their departure harms the poor. To mitigate such harm, researchers have proposed a variety of policies designed to tax or restrict high-skill migration. Those policies have been justified as Pigovian regulations to raise efficiency by internalizing externalities, and as non-Pigovian regulations grounded in equity or ethics. This paper challenges both sets of justifications, arguing that Pigovian regulations on skilled emigration are inefficient and non-Pigovian regulations are inequitable and unethical. It concludes by discussing a different class of policy intervention that, in contrast, has the potential to raise welfare.
Peripartum cardiomyopathy – risk factors, characteristics and long-term follow-up

Published: June 2014

Abstract

Aims: Peripartum cardiomyopathy (PPCM) is an infrequent form of cardiomyopathy causing significant maternal morbidity and mortality. We aimed to evaluate the risk factors, characteristics and prognosis of PPCM during the index and subsequent pregnancies.

Methods: A retrospective cohort of 36 women with PPCM in a tertiary medical center was analyzed and compared with 10,370 women who gave birth during a single calendar year at the same institution.

Results: Women diagnosed with PPCM were older (mean 33.5 years) than controls. A significantly higher proportion were primiparous (63.9%), carried multifetal pregnancies (33.3%) and had hypertensive pregnancy complications (38.9%). Thirty-six percent of PPCM patients conceived with in vitro fertilization, and six of them received ovum donation. Twenty-two women had severe left ventricular dysfunction at diagnosis, and these women tended to remain with residual disease, compared with women with milder ventricular dysfunction at diagnosis. Eight patients recovered completely within 2 weeks of diagnosis. Women who recovered early (n=8) had significantly higher ejection fractions on last follow-up compared with women (n=28) who had late or partial recovery. Nine women had 14 additional pregnancies; of them eight women had normal cardiac functions on subsequent pregnancy.

Conclusions: Risk factors for peripartum cardiomyopathy include primiparity, hypertension and multifetal pregnancies. Assisted reproduction techniques are not independently associated with PPCM but rather through other risk factors for PPCM. The degree of cardiac dysfunction at diagnosis and time to recovery are important prognostic factors.

Properties of PVA-reinforced cement-bonded fiberboards processed with calender extrusion
Authors: Pekmezci Bekir Y. 
Published: June 2014

Abstract
This research investigates the application of calender extrusion as a novel technique in the production of cement fiberboards. The technique is successfully used in the production of non-structural building elements. The properties of the produced composites are discussed in this paper, particularly with regards the polyvinyl alcohol (PVA) fiber used in the study. The research involves an experiment to examine the mechanical properties and microstructure of the composites, and the results indicate that calender extrusion is a promising method for the production of thin and wide cement composites. These products can be shaped into various three-dimensional forms in the green state after processing. Based on the results, the mechanical properties of cement-bonded fiberboards vary with processing direction due to the alignment of fibers. Fiber content is the most significant factor with regards the tensile and flexural properties of fiber-reinforced cementitious products processed with calender extrusion. Moreover, processed composites have adequate screw head pull-through and freeze-thaw resistance.
Non-parametric estimation of copula parameters: testing for time-varying correlation
Authors: Gong Jinguo , Wu Weiou , McMillan David , Shi Daimin 
Published: June 2014

AbstractThe correlation structure of financial assets is a key input with regard to portfolio and risk management. In this paper, we propose a non-parametric estimation method for the time-varying copula parameter. This is achieved in two steps: first, displaying the marginal distributions of financial asset returns by applying the empirical distribution function; second, by implementing the local likelihood method to estimate the copula parameters. The method for obtaining the optimal bandwidth through a maximum pseudo likelihood function and a statistical test on whether the copula parameter is time-varying are also introduced. A simulation study is conducted to show that our method is superior to its contender. Finally, we verify the proposed estimation methodology and time-varying statistical test by analysing the dynamic linkages between the Shanghai, Shenzhen and Hong Kong stock markets.
Analyse der räumlichen Verlustleistungsdichteverteilung bei der bipolaren Elektrochirurgie
Authors: Knopf Christoph , Himmel Jörg , Rübesam Markus , Klöckner Stephan , Kanoun Olfa 
Published: June 2014

ZusammenfassungDie transurethrale Resektion der Prostata (TUR-P) ist der Gold Standard für die endoskopisch-chirurgische Behandlung der Benignen Prostatahyperplasie (BPH). Unbekannt ist jedoch, ob bei der bipolaren TUR-P die Möglichkeit von elektrothermischen Verletzung von benachbartem nichtopertiertem Gewebe besteht. Grund hierfür könnten höhere Ausgangsleistungen der Chirurgie-Generatoren sein. Deshalb werden experimentell gemessene Werte der räumlichen Verlustleistungsdichte um ein bipolares Resektoskop als Quellterm für die Berechnung der Temperaturänderung im operationsnahen Gewebe verwendet. Die Temperaturberechnung basiert auf der numerischen Lösung der Wärmeleitungsgleichung nach Penne. Für die gewählten Randbedingungen und Eingabeparameter sind keine signifikanten Temperaturerhöhungen im Berechnungsgebiet am proximalen Ende des Resektoskop-Schaftes festzustellen. Um ein umfassendes Verständnis zu gewinnen sollen weiterführende Untersuchungen mit einer Variation der Randbedingungen und Eingabeparameter durchgeführt werden.

Published: June 2014

AbstractThere is an increasing tendency towards the use of combined MR/PET scanners and combined MR-Linac (Linear accelerator) systems in both clinical and research settings. The current work therefore investigated the effects of ionising radiation on the acquired MR signal, both experimentally and using a simple theoretical model. We have observed a phase signal change in the radiated area inside a water phantom. However, the theoretical basis of this observation is not fully covered by the employed model and needs further research.
Antecedent contained deletion in the domain of a raised object
Authors: Tanaka Hidekazu 
Published: June 2014

AbstractWhen a verb takes two complements, the first complement, typically an accusative object, c-commands the second complement, and the second complement can host a relative clause containing antecedent contained deletion (ACD). This simple fact, which, upon careful considerations, reveals that English accusative objects raise to a higher position than previously thought. The theoretical claim is that objects raise to check Case to the outer vP-spec. We argue that the v consists of two separate heads, the higher v
