Authors: Quintãns Cláudia , Alberto Isabel , Machado Carla
Published: November 2014

O estudo apresentado neste artigo teve como objectivo conhecer as narrativas de adultos que foram alvo de institucionalização na sua infância e/ou adolescência, em duas condições distintas: i) acolhimento prolongado em Lar de Infância e Juventude, após terem sido identificados como vítimas de maus-tratos e ii) colocação em Centro Educativo, após a sua identificação como autores de facto(s) qualificado(s) como crime pela Lei Penal Portuguesa. Foram recolhidas as narrativas de catorze participantes, salientando o que percepcionaram como aspectos positivos e como aspectos negativos da experiência de institucionalização, as suas vivências da mesma, bem como sugestões no sentido de melhorar a qualidade destes serviços. Os resultados sugerem que a institucionalização comporta aspectos positivos e negativos, que foram claramente enunciados pelos participantes do nosso estudo.
Preparação para a Reforma: Responsabilidade individual e colectiva
Authors: França Lucia Helena de Freitas Pinho
Published: November 2014

Uma das conseqüências do avanço da medicina e da queda da natalidade foi o aumento da expectativa de vida, observado tanto nos países desenvolvidos quanto nos periféricos. Assim, o maior desafio para este século será manter as pessoas mais velhas activas, independentes e participativas, como recomendado pela Organização Mundial de Saúde. No mundo do trabalho, é preciso garantir a livre escolha do trabalhador frente a sua aposentadoria ou continuidade no mercado, e as medidas a serem tomadas para seu bem-estar no futuro. Neste artigo são abordados os preconceitos contra a idade e as atitudes frente à aposentadoria, a atualização da mão-de-obra mais velha, e o Programa de Preparação para a Reforma (PPR). São discutidos ainda os projetos intergeracionais que intercambiam a experiência e o conhecimento dos mais jovens e mais velhos, como um processo de transferência e valorização do patrimônio humano e histórico da organização.
Necessidade de cognição, memória de trabalho e recuperação de contra-exemplos para condicionais causais
Authors: Couto Marta , Quelhas Ana Cristina , Juhos Csongor
Published: November 2014

A procura de contra-exemplos é provavelmente a fase mais importante do raciocínio dedutivo, uma vez que visa garantir a validade da conclusão. A explicação mais difundida para a diminuta procura de contra-exemplos é a capacidade limitada da memória de trabalho (Markovits & Barrouillet 2002; De Neys, Schaeken & d’Ydewalle, 2002; 2003; 2005a; 2005b) o que não parece ser suficiente para explicar a pouca iniciativa dos sujeitos em utilizarem a procura de contra-exemplos como estratégia de verificação (Oakhill, & Johnson-Laird, 1985). No presente trabalho testou-se a hipótese de que a necessidade de cognição dos sujeitos (Cacioppo & Petty, 1982) tem influência no processo de recuperação de contra-exemplos, para condicionais causais, de modo aprofundar o conhecimento das razões que levam a que os sujeitos procurem tão poucos contra-exemplos durante o raciocínio dedutivo (Oakhill, & Johnson-Laird, 1985; Johnson-laird, 2006). Para o efeito, um total de 60 participantes (15 alunos do mestrado integrado em psicologia, 15 alunos de doutoramento, 15 operários fabris e 15 empregados de mesa) realizou 3 tarefas: escala Necessidade de Cognição (Silva & Garcia-Marques, 2006), uma tarefa de raciocínio e uma tarefa para avaliar a capacidade da memória de trabalho (Guerreiro, Quelhas & Garcia-Madruga, 2006). Os resultados indicam que o processo de recuperação de contra-exemplos é influenciado pela necessidade de cognição e que esta influência além de significativa é superior à influência da capacidade da memória de trabalho.
Resonant Alterities
Authors: Mieszkowski Sylvia
Published: November 2014

»Resonant Alterities« bridges the gap between sound studies and literary criticism. A queer ghost story by Vernon Lee, an occultist novel of psychic adventure by Algernon Blackwood, a dystopian science fiction tale by J.G. Ballard and a post-traumatic short novel by Don DeLillo are its primary objects of analysis. Each is explored within the context of its contemporary cultural debates on sound. Meanwhile, all four theory-enriched readings focus on intersecting and desire-laden processes of meaning making, knowledge production and subject formation. Focal points are aurally/audio-visually structured phenomena expressive of both collective and individual anxieties.

Published: November 2014

Seit dem 20. Jahrhundert hat sich die Gesellschaft in den Weltraum ausgedehnt. Einerseits hängen Kommunikation, Sicherheit und Wissen von weltraumgestützten Systemen ab, andererseits bricht durch die bemannte Raumfahrt die Gesellschaft faktisch in den Kosmos auf. Dieser Band startet eine Sonde in einen soziologisch ziemlich unbekannten Gesellschaftsraum. Er erklärt die conditio humana der Weltraumfahrt und sichtet Weltraumkonzepte und Astronautik in der modernen Diskursordnung, für die globale Sicherheit, in der Architektur und in der Massenkultur. Mit Gastbeiträgen von Heike Delitz und Helmuth Plessner (1892-1985), der schon früh die Bedeutung der Kosmonautik antizipierte.
Ästhetische Erfahrung in der Literatur der 1970er Jahre
Authors: Bandeili Angela
Published: November 2014

Nach 1968 ist eine Literatur entstanden, die bis heute mit gesellschaftspolitischen Schlagworten wie »Tendenzwende« oder »Neue Subjektivität« aufgeladen ist. Angela Bandeili bietet einen neuen Blick auf zentrale Texte der 1970er Jahre - von Alexander Kluge, Rolf Dieter Brinkmann und Peter Handke - und rückt dabei das konkrete Erfahrungsangebot der Texte in den Mittelpunkt: Material, Subjekt und Medium sind die Produktionskategorien, die das eigentlich »Neue« zutage fördern und dabei immer auch kulturhistorisch relevant sind. Die Studie lässt so eine intermediale Form der Organisation und eine Poetologie des Raumes erkennbar werden.

Extraterritorial Discovery in Aid of Execution and State Immunity: Case Comment on Republic of Argentina v. NML Capital, Ltd., 573 U.S. ___ (2014)
Authors: Ishikawa Tomoko
Published: November 2014

On 16 June 2014, the Supreme Court of the United States rejected the petition for a writ of certiorari stemming from the dispute over the meaning of the pari passu clause in the Argentine sovereign bonds. This decision had a dramatic impact on Argentina’s sovereign debt restructurings (SDR) – indeed, it arguably led to Argentina’s second default in 13 years on 30 July 2014. On the same day that the petition for certiorari was rejected, the Supreme Court rendered a judgment on the issue of the relationship between discovery in aid of execution against the debtor state’s extraterritorial assets and the law of state immunity. In Republic of Argentina v. NML Capital, Ltd., judgment of 16 June 2014, the Supreme Court affirmed the Second Circuit’s conclusion that the extraterritorial assets discovery against two non-party banks in aid of executing the judgments stemming from Argentina’s default of its external debt did not offend Argentina’s sovereign immunity. This comment addresses this judgment on extraterritorial discovery which, although less headline grabbing than the decisions on the pari passu clause, also marks a victory for holdout creditors. It first provides a summary of the background of the case and the judgment, and then considers its implications on the future SDR. Regarding the implications of the case on the future SDR, this comment also describes the developments of law concerning the relationship between the law on foreign investment and SDR (in investment arbitration) and the relationship between investment arbitration awards and sovereign immunity (in US courts). First, it examines the recent decisions in ICSID arbitration concerning the disputes arising from the Argentina’s default and subsequent SDR (Abaclat v. Argentina (decision on jurisdiction and admissibility of 4 August 2011) and Ambiente v. Argentina (decision on jurisdiction and admissibility of 8 February 2013)). In essence, these decisions opened the door to investment treaty arbitration for holdout creditors of international sovereign bonds, for the first time in the history of investment arbitration. It then describes the Second Circuit’s recent decision in Blue Ridge v. Argentina (judgment of 19 August 2013) in which the court concluded that the defendant state in an ICSID arbitration was considered to have waived its jurisdictional immunity under the Foreign State Immunity Act of 1976 (FSIA). It argues that the combination of: (a) Argentina v. NML, (b) Blue Ridge v. Argentina, and (c) the openness of ICSID arbitration to disputes arising from SDR will have potentially serious consequences for future SDR.

Published: November 2014

Skin tissue is not only responsible for thermoregulation but also for protecting the human body from mechanical, bacterial, and viral insults. The mechanical properties of skin tissue may vary according to the anatomical locations in the body. However, the linear elastic and nonlinear hyperelastic mechanical properties of the skin in different anatomical regions and at different loading directions (axial and circumferential) so far have not been determined. In this study, the mechanical properties during tension of the rat abdomen and back were calculated at different loading directions using linear elastic and nonlinear hyperelastic material models. The skin samples were subjected to a series of tensile tests. The elastic modulus and maximum stress of the skin tissues were measured before the incidence of failure. The nonlinear mechanical behavior of the skin tissues was also computationally investigated through a constitutive equation. Hyperelastic strain energy density function was calibrated using the experimental data. The results revealed the anisotropic mechanical behavior of the abdomen and the isotropic mechanical response of the back skin. The highest elastic modulus was observed in the abdomen skin under the axial direction (10 MPa), while the lowest one was seen in the back skin under axial loading (5 MPa). The Mooney-Rivlin material model closely addressed the nonlinear mechanical behavior of the skin at different loading directions, which can be implemented in the future biomechanical models of skin tissue. The results might have implications not only for understanding of the isotropic and anisotropic mechanical behavior of skin tissue at different anatomical locations but also for providing more information for a diversity of disciplines, including dermatology, cosmetics industry, clinical decision making, and clinical intervention.

The aim of the study was to describe automated immunoassays for autoantibodies to homocitrulline or citrulline containing telopeptides of type I and II collagen in various disease categories in an early arthritis series.

Serum samples were collected from 142 patients over 16 years of age with newly diagnosed inflammatory joint disease. All samples were analyzed with an automated inhibition chemiluminescence immunoassay (CLIA) using four different peptide pairs, each consisting of a biotinylated antigen and an inhibiting peptide. Assays were performed with an IDS-iSYS analyzer. Autoantibodies binding to homocitrulline and citrulline containing C-telopeptides of type I (HTELO-I, TELO-I) and type II collagens (HTELO-II, TELO-II) were analyzed.

The mean ratio of HTELO-I inhibition in seropositive and seronegative rheumatoid arthritis (RA) was 3.07 (95% CI 1.41–11.60), p=0.003, and in seropositive and seronegative undifferentiated arthritis (UA) 4.90 (1.85–14.49), p<0.001. The respective mean ratios in seropositive and seronegative RA and UA were in TELO-I 8.72 (3.68–58.01), p<0.001 and 3.13 (1.49–6.16), p=0.008, in HTELO-II 7.57 (3.18–56.60), p<0.001 and 2.97 (1.23–6.69), p=0.037, and in TELO-II 3.01 (1.30–9.51), p=0.002 and 3.64 (1.86–7.65), p=0.008. In reactive arthritis, ankylosing spondylitis, psoriatic arthritis and unspecified spondyloarthritis the inhibition levels were similar to those observed in seronegative RA or UA.

Autoantibodies binding to homocitrulline or citrulline containing telopeptides of type I and II collagen did not differ significantly. They were highest among patients with seropositive disease and they differentiated seropositive and seronegative arthritis.

Published: November 2014

The aquation reaction of the oxydiacetate cobalt(II) complex, namely [Co(ODA)(H2O)2]•H2O (ODA = oxydiacetate), induced by the Fe(III) ions as the promoter has been studied spectrophotometrically (UV-Vis). Kinetic measurements were carried out in the 283.15 - 303.15 K temperature range and at a constant ionic strength of
1.0 M (NaNO3). The observed rate constants were computed by a program based on global analysis. Furthermore, the reaction activation parameters were determined using the Arrhenius and Eyring equations. The changes in the enthalpy, entropy as well as activation energy barriers were calculated in the range of 0.00125 M – 0.125 M of the Fe(III) ion concentration. Based on kinetic data a mechanism for the aquation of the [Co(ODA)(H2O)3] complex has been proposed.

Published: November 2014

Ionic liquid (IL) synergy with other materials may influence their properties significantly. Nevertheless, their advantageous liquid state turns out to be an impediment for applications in devices which need stable solid state shaping. In the current study we present a novel method where new siloxane functionalized IL acts as a modifier for carbon nanotubes (CNTs) and titanium alkoxide-CNT coated hybrid cotton fibers. This elaborated route carried out by interconnected and entangled ionic liquid, sol-gel and solid carbon nanotube networks opens up opportunities for functionalization of sol-gel materials with different shapes and sizes. The comparison of properties of IL, ionogel, ionogel/CNT mixture and titanium alkoxide coatings is performed. Ionogel-modified cotton fibers have increased hydrophobicity, linear density, breaking force and ultimate strength as compared to the uncoated cotton fibers. These properties are ensured even after washing threads with water. A uniformly coated CNT network around the fibers strengthens the material and increases its electric conductivity.
New type of hybrids can be utilized in formulations which have UV-shielding and hydrophobic properties as well as for antibacterial properties. Characterization studies of the product were carried out by energy-dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM), optical microscopy and infrared (IR) spectroscopy.
Alkali roasting of bomar ilmenite: rare earths recovery and physico-chemical changes
Authors: Sanchez-Segado Sergio , Lahiri Abhishek , Jha Animesh
Published: November 2014

In this work, the alkali roasting of ilmenite
(FeTiO3) is presented as a process route for integrated beneficiation of the mineral for rutile-rich phase and rare earth oxides; the latter is released as a consequence of physical changes in the ilmenite matrix, during the water leaching after roasting. The oxidative alkali roasting transforms ilmenite mineral into water-insoluble alkali titanate and water-soluble ferrite. After roasting the insoluble alkali titanate is separated from rare-earth oxide mixture in colloidal form and water-soluble ferrite. Further leaching of alkali titanate is carried out with oxalic (0.3M) and ascorbic (0.01M) acid solution which removes the remaining Fe2+ ions into the leachate and allows precipitation of high-purity synthetic rutile containing more than 95% TiO2. Iron is removed as iron oxalate. The physico-chemical changes occurred during the roasting and leaching processes are reported by comparing the role of alkali on the roasting process and product morphologies formed.

Catalytic activity of solvothermally-synthesized hexagonal molybdenum trioxide (h-MoO3) in epoxidation of 1-octene by tert-butyl hydroperoxide and the effect of deposition of metal (Ag, Pd, Cu) nanoparticles on the properties of catalyst have been investigated. It has been shown that silver-modified MoO3 demonstrates the highest catalytic activity and selectivity in the reaction of
1,2-epoxyoctane formation, whereas MoO3 modified with Pd nanoparticles exhibits worse catalytic performance than bare MoO3; by contrast, copper-modified MoO3 does not catalyze the epoxidation reaction. The Ag/MoO3 catalyst was also found to be active in the reaction of 1-octene oxidation by molecular oxygen at the initial stage of the oxidation process.
Mixed-ligand complexes of copper(II) ions
with L-glutamic acid in the systems
with triamines and non-covalent interaction between bioligands in aqueous solution
Authors: Bregier-Jarzebowska Romualda
Published: November 2014

The interactions between L-glutamic acid (Glu) and 1,7-diamino-4-azaheptan (3,3-tri) and 1,8-diamino-4-azaoktan (Spd) in metal-free systems and in the appropriate Cu(II) ions complexes were studied by potentiometric and spectral methods. The composition and overall stability constants of complexes forming in the systems studied were determined and the reactions centres were identified. In the complex formation conditions, the ligands have positive and negative reaction centres, which are also the potential sites of metal coordination. Below pH 7 in metal-free systems, the terminal amine groups from both triamines and the oxygen atoms from –C(5)OO- group as well as the amine group from Glu do not take part in the weak noncovalent interactions between the ligands, but at higher pH all available active centres of the ligands are involved in the interactions in the adducts formed and the inversion effect is observed. In the Cu(II)/Glu/triamine systems, in the species MLHL’, both 3,3-tri and Spd were found to coordinate Cu(II) ions in the same way, while only in the Cu(Glu)H(Spd) complex the oxygen atoms from –C(5)OO- group of the amino acid do not take part in metallation. In the species MLL’ and MLL’OH with 3,3-tri, the chromophore formed was of different type than that formed in the corresponding species with Spd. This is related to the fact that the nitrogen atom from the amine group of Glu is inactive in the coordination. Thus, not only the length of the polyamine carbon chain but also the length of the amino acid carbon chain influence the interactions between the bioligands. The introduction of metal ions to Glu-Spd metal-free system excludes the interaction between the bioligands, and the ligands centres that do not take part in the weak interactions in the adduct (Glu)H(Spd) are involved in the metallation, but the centres that took part in the weak interactions are not involved in the coordination in a heteroligand complex.
An Equation Decomposition Based Tailored Finite Point Method
for Linearized Incompressible Flow in Two-Dimensional Space
Authors: Li Ye , Han Houde , Huang Zhongyi
Published: November 2014

In this paper, we propose a tailored finite point method for linearized incompressible flow
(Oseen equations) in two dimensions based on the equation decomposition technique.
Unlike the usual vorticity-stream function formulation,
the velocities are decomposed to irrotational and rotational parts.
We only need to solve a system of two elliptic equations which are decoupled in the interior domain.
They are only coupled in boundary conditions.
When the domain is unbounded, we use the artificial boundary method to reduce the original
problem to a problem on a bounded computational domain.
Our finite point method has been tailored to some particular properties of the
problem. Therefore, our scheme satisfies the discrete maximum principle in the interior domain automatically.
We also give some remarks on more generally linearized incompressible flow,
and it can be considered as the first step to solve the incompressible Navier–Stokes problem.
Finally, several numerical examples show the efficiency and feasibility of our method
whatever the Reynolds number is small or large.
Reflections on the Study of Generations in Politics
Authors: Stoker Laura
Published: November 2014

Political scientists often use the lens of generations when studying how the political views of citizens develop and how the polity as a whole evolves. This essay provides an overview of the topic: distinguishing work on lineage generations from that on political generations while also addressing their intersection; describing the Age-Period-Cohort (APC) framework used to study political generations and illustrating the difficulty of distinguishing cohort from age and period effects; and reflecting on the difficulty of explaining generational differences. The essay closes with a discussion of the many ways in which America’s youngest citizens are politically different from their elders.
More Than a Trace: Political Periods, Presidential Losers, and the Goldwater and McGovern Experiences
Authors: Busch Andrew E.
Published: November 2014

Periods of American politics marked by recognizable surges of ideas and activists are not driven solely by winners. Barry Goldwater and George McGovern were among the biggest losers in the history of American presidential elections, yet they produced surges that continue to affect American politics decades later. These losing candidates had three things in common: 1) Their candidacies represented more than individual attempts to gain the presidency, 2) they altered their parties’ electoral coalitions and strategies, and 3) they each made distinctive arguments that laid the groundwork for future party and movement successes.

The purpose of this study is to spatiotemporallyexplore the characteristics of urban temperaturesbased on multi-temporal satellite data and historical insitu measurements. As one of the most rapidly urbanizedcities in Canada, Saskatoon (SK) was selected as our studyarea. Surface brightness retrieving, Pearson correlation,linear regression modeling, and buffer analysis were appliedto different satellite datasets. The results indicatethat both Landsat and MODIS data can yield pronouncedestimations of daily air temperature with a significantlyadjusted R2 of 0.803 and 0.518 at the spatial scales of 120mand 1000 m, respectively. MODIS monthly LST data ishighly suitable for monitoring the trend of monthly urbanair temperature throughout summer (June, July, and August)due to a high average R2 of 0.8 (P<0.05), especiallyfor the warmest month (July). Our findings also reveal thatboth the Saskatchewan River and urban green spaces havestatistically significant cooling effects on the surroundingurban surface temperatures within 500 m and 200 m, respectively.In addition, a multiple linear regression modelwith four influential factors as independent variables canbe developed to estimate urban surface temperatures witha highest adjusted R2 of 0.649 and a lowest standard errorof 0.076.

Analysis and approximation of frictionless contact problems between two piezoelectric bodies with adhesion
Authors: Hadj Ammar Tedjani , Drabla Salah , Benabderrahmane Benyattou
Published: November 2014

We consider a mathematical frictionless contact problem between two electro-elastic bodies. The contact is modelled with normal compliance and adhesion. We provide a variational formulation for the problem and prove the existence of a unique weak solution. The proofs are based on arguments of time-dependent variational inequalities, the Cauchy–Lipschitz Theorem and the Banach Fixed-Point Theorem. Then, a discrete scheme is introduced based on the finite element method to approximate the spatial variable. Furthermore, we provide optimal a priori error estimates for the displacements, the electric potential and the bonding at the contact interface.

Published: November 2014

The current work is devoted to the second-generation biodiesel production via fatty acids catalytic hydrodeoxygenation (HDO). Pd-containing catalysts based on polymeric matrix of hypercrosslinked polystyrene (HPS) with different metal loading were investigated in the process. The catalysts were characterized by low-temperature nitrogen physisorption, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The selectivity of the process (regarding to n-heptadecane) reached up to 99% at 100% conversion. The optimal reaction conditions which allowed achieving high selectivity at 100% of stearic acid conversion were chosen.
Assumption Trade-Offs When Choosing Identification Strategies for Pre-Post Treatment Effect Estimation: An Illustration of a Community-Based Intervention in Madagascar
Authors: Weber Ann M. , van der Laan Mark J. , Petersen Maya L.
Published: November 2014

Failure (or success) in finding a statistically significant effect of a large-scale intervention may be due to choices made in the evaluation. To highlight the potential limitations and pitfalls of some common identification strategies used for estimating causal effects of community-level interventions, we apply a roadmap for causal inference to a pre-post evaluation of a national nutrition program in Madagascar. Selection into the program was non-random and strongly associated with the pre-treatment (lagged) outcome. Using structural causal models (SCM), directed acyclic graphs (DAGs) and simulated data, we illustrate that an estimand with the outcome defined as the post-treatment outcome controls for confounding by the lagged outcome but not by possible unmeasured confounders. Two separate differencing estimands (of the pre- and post-treatment outcome) have the potential to adjust for a certain type of unmeasured confounding, but introduce bias if the additional identification assumptions they rely on are not met. In order to illustrate the practical impact of choice between three common identification strategies and their corresponding estimands, we used observational data from the community nutrition program in Madagascar to estimate each of these three estimands. Specifically, we estimated the average treatment effect of the program on the community mean nutritional status of children 5 years and under and found that the estimate based on the post-treatment estimand was about a quarter of the magnitude of either of the differencing estimands (0.066 SD vs. 0.26–0.27 SD increase in mean weight-for-age z-score). Choice of estimand clearly has important implications for the interpretation of the success of the program to improve nutritional status of young children. A careful appraisal of the assumptions underlying the causal model is imperative before committing to a statistical model and progressing to estimation. However, knowledge about the data-generating process must be sufficient in order to choose the identification strategy that gets us closest to the truth.

European Society of Cardiology Guidelines cite
results of meta-analysis that the use of calcium channel
blockers results in fewer angina episodes per week vs.
long-acting nitrates. Moreover, we listed 12 reasons more
to prefer amlodipine over long-acting nitrates, especially
in stable angina pectoris patients with arterial hypertension.
It may be the way to decrease polypharmacy without
loosing efficacy. Some important advantages of amlodipine
versus long-acting nitrate(s) are: amlodipine also
treats hypertension, it helps reducing hypertensive target organ damages (e.g. left ventricular hypertrophy) and prevents
morning blood pressure surge. Moreover, amlodipine
can be given once daily (which improves adherence),
it produces neither tolerance nor rebound, it has less side
effects.

Eosinophilia is characterized by more than 0.5 x 10

We report a case of 59-year old female who started a special weight-reducing diet regimen that included excessive cashew nut ingestion. Several months after she has presented with periferal blood eosinophilia and constitutional symptoms. Detailed work-up has not found elements for haematological, systemic autoimmune, neoplastic or infectious disease. She was diagnosed with eosinophilia- myalgia syndrome due to extreme L-tryptophan intake, a compound found in the cashew nut’s oil. She responded well to cashew nut withdrawal and steroid therapy. In the follow-up period she remained stable with normal eosinophil count and there was not a need for any specific therapy

This paper focuses on the single state feedback
stabilization problem of unified chaotic system and circuit
implementation. Some stabilization conditions will
be derived via the single state feedback control scheme.
The robust performance of controlled unified chaotic systems
with uncertain parameter will be investigated based
on maximum and minimum analysis of uncertain parameter,
the robust controller which only requires information
of a state of the system is proposed and the controller is
linear. Both the unified chaotic system and the designed
controller are synthesized and implemented by an analog
electronic circuit which is simpler because only three variable
resistors are required to be adjusted. The numerical
simulation and control in MATLAB/Simulink is then provided
to show the effectiveness and feasibility of the proposed
method which is robust against some uncertainties.
The results presented in this paper improve and generalize
the corresponding results of recent works.

In this work, we investigated the effect of aluminum chloride hexahydrate as a flame retardant coating on the flammability of cellulosic and polyester (polyethylene terephthalate, PET) fibers. The samples were characterized by several techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, vertical flammability test, limiting oxygen index (LOI), thermogravimetric analysis (TGA)and differential thermogravimetric (DTG). Aluminum chloride hexahydrate <100 nm in size has been found to form continuous and dispersed particles coatings on the fibers surface which shows efficient flame retardant properties. The optimum loadings to impart flame retardant properties were about 8.73–9.93% for cellulosic fiber and 20.30–23.48% for polyester fiber. Flame retardant activity was tested by a vertical flammability tester and LOI. XRD results of ashes revealed that after combustion of the treated specimens, the existence of α-Al2O3 nanoparticles was detected in the ashes of treated samples. TGA/DTG of pure, treated fibers and the salt was accomplished, and thermograms were compared and discussed. The results obtained are in favor of the free radical theory and also the dust or wall effect theory.

Detonation nanodiamonds (ND) present a significant part of nanocarbons group, which could be produced on commercial scale by detonation
of explosives in a closed chamber. Their unique properties of high surface area, low weight and radiation resistance make ND
a prospective candidate for applications in sorption processes in radiochemistry. To study the influence of surface chemistry on
sorption properties, apristine sample of ND was treated with acids and hydrogen. The surface chemistry of the samples was characterised
by infrared spectroscopy, X-ray photoelectron spectroscopy and Boehm titration. The sorption properties of ND were tested fordifferent
radionuclides. The sorption capacity of ND was shown to be higher than those of commonly used radionuclide sorbents like activated
carbon and compariable to other members of nanocarbon group like graphene oxide and carbon nanotubes. The sorption properties were
shown to be influenced by the presence of oxygen-containing groups on the surface of ND. This represents an opportunity to increase the
sorption capacity of ND.

Testing for short-run threshold effects in a vector error-correction framework: a reappraisal of the stability of the US money demand
Authors: Lieb Lenard , Candelon Bertrand
Published: November 2014

In this paper we analyze the stability of the money demand system in the US. To this aim, we develop an estimation and testing framework for a threshold vector error-correction model (VECM), where short-run dynamics are regime dependent and are driven by an exogenous, stationary and ergodic threshold variable. We modify a traditional Wald-type test for linearity and derive its asymptotic distribution, which turns out to be non-standard, but similar to the one proposed by Andrews [Andrews, D. 1993. “Tests for Parameter Instability and Structural Change with Unknown Change Point.”Econometrica61 (4): 821–856]. Accounting for the diversity of the potential determinants of money holdings, a broad scope of money demand systems is analyzed. The linearity test confirms that money demand is not only suffering from structural breaks, but is driven by regimes governed by business cycles. Moreover, a similar pattern and a robust dating of the regimes is observed no matter the money demand system considered, offering hence a reconciling picture of previous empirical studies. From a policy perspective, our findings supports the implementation of cyclical monetary policy by the Federal Reserve.
Moves and steps to sell a paper: a cross-cultural genre analysis of applied linguistics conference abstracts

Published: November 2014

Conference abstracts are under-represented promotional texts in spite of their key role in the academic life of and communication among scholars. This generic study attempts to capture the structures and strategies of 160 applied linguistics conference abstracts from four world areas in terms of semantic units of Introduction, Method, and Findings and their Moves and Steps. Results revealed similarities and differences arising mainly from the idiosyncratic nature of genre, place of presentation, and western versus non-western, center versus periphery, and theory- versus application-oriented cultures. Implications for novice and non-native researchers to communicate and submit conference abstracts effectively follow a detailed report.
Balancing multiple roles through consensus: making revisions in haircutting sessions
Authors: Oshima Sae
Published: November 2014

This study demonstrates how participants in haircutting sessions merge different roles during one of the most sensitive moments of an encounter: requesting and/or making revisions to a new cut. During the process of arriving at a consensus of whether or not changes need to be made to the new cut, the stylist and the client negotiate not only the quality of the cut, but also their expected roles. Caring about both the bodies and the minds of customers is an important element in measuring the quality of cosmetological services, a consideration which may oblige stylists to immediately agree with and act upon every client request or concern. However, simply yielding to the customer’s opinions can threaten the stylist’s role as a beauty expert, one who possesses their own professional standards. The analysis reveals that the participants frequently transform revision requests/offers into mutual decisions through a combination of verbal and bodily actions. In doing so, they harmonize the sometimes conflicting responsibilities of “service provider/patron” and “expert/novice.”
Quantification of Anisotropy-Related Uncertainties in Relative Photoluminescence Quantum Yield Measurements of Nanomaterials – Semiconductor Quantum Dots and Rods
Authors: Würth Christian , Geißler Daniel , Resch-Genger Ute
Published: November 2014

In order to assess the anisotropy-related uncertainties of relatively
determined photoluminescence quantum yields (Φ
PL) of
molecular emitters and luminescent nanomaterials, we compared
Φ
PL values measured without and with polarizers using
magic angle conditions and studied systematically the dependence of
the detected emission intensity on the polarizer settings for samples
of varying anisotropy. This includes a dispersion of a spherical
quantum dot (QD) with an ideally isotropic emission, a solution of
a common small organic dye in a fluid solvent as well as dispersions
of elongated quantum dot rods (QDR) with an anisotropic luminescence
and a small organic dye in a rigid polymeric matrix, as ideally
anisotropic emitter. Our results show that for instruments lacking
polarizers, anisotropy-related measurement uncertainties of relative
photoluminescence quantum yields can amount to more than 40%,
with the size of these systematic errors depending on the difference
in emission anisotropy between the sample and the standard.
Physical Modeling on Ground Responses to Tunneling in Sand Considering the Existence of HDPE Pipes

Published: November 2014

Ground settlement and relevant prediction methods related to underground tunneling have been investigated extensively in previous studies. However, the effects of the existence of service pipelines on the ground movement induced by tunneling have not been well addressed. This study involved a series of physical modeling tests on ground responses to tunneling in sand considering the existence of high-density polyethylene (HDPE) pipes using a custom-made physical modeling system. The system included a model box, a pipe fixing frame, and a number of settlement plates. The developed model box had dimensions of 2.0 m by 2.0 m by 1.5 m, and the bottom of the box consisted of eight movable plates with dimensions of 0.25 m by 2 m by 0.1 m. The plates were lowered down at four levels of maximum vertical distance (10, 20, 30, and 40 mm) to form normal distribution curves, simulating tunneling effects in the sand stratum. Four normal distribution curves were created with maximum lowering distances of the movable plates of 10, 20, 30, and 40 mm to simulate different volumes of ground loss in the tunnel. We performed the four tests one after another by successively lowering down the movable bottom plates. Prior to filling, the required density of backfilled sand was determined using a self-designed instrument. The HDPE pipes, with two diameters (i.e., 300 and 200 mm), were installed in the model box at two different buried depths (i.e., 1.05 and 0.75 m from the spring line of the pipes to the fill surface) using a custom-made fixing frame. The test results demonstrate that the existence of the HDPE pipes resulted in a wider but shallower settlement trough than in the greenfield (without pipe) case. The width of the settlement trough at a given depth decreased with decreasing buried depth of the pipe, whereas it increased with decreasing pipe diameter. The volume of the settlement trough at a given depth was approximately constant, regardless of the existence of pipes, and the vertical displacement of the pipes increased with decreasing diameter and buried depth of the pipe.

Published: November 2014

This paper presents an experimental study in which laboratory tests were conducted to investigate how the different interlayers (between the pavement surface slabs and the bases) could improve the performances of vibration response and anti-erosion of the bases. In the tests for vibration response of the bases, geotextile and rubber sheet were used as the interlayers, and the micro-seismic testing system was employed to characterize the vibration response of bases of concrete pavements beneath different interlayers under impact loading. The vibration test results indicated that under the same impact loading, compared with the bases without an interlayer atop, vector sum of the maximum vibration velocity of the bases beneath a rubber sheet interlayer and two layers of geotextile interlayer decreased by 35 % and 80 %, respectively; and vector sum of their maximum vibration displacement decreased by 18 % and 26 %, respectively. In the laboratory tests for anti-erosion, the bases with geotextile or emulsified asphalt slurry seal as the interlayer atop were tested for performances of resisting water erosion via a self-made testing apparatus. The anti-erosion test results indicated that, under the same other conditions, compared with the bases without an interlayer atop, the erosion rate (after 12 min of testing) of the bases with geotextile or emulsified asphalt slurry seal as interlayers atop decreased by 99 % or 59 %, respectively. The interlayer has the effects of damping vibration and resisting water erosion on the pavement base.
