The diffracted field and its gradient near the edge of a thin screen
Authors: Hewett David P. , Svensson U. Peter
Published: December 2013

The secondary edge source line integral formulation for diffraction modeling uses edge sources with a 1/r dependency, in addition to a directivity function. At first sight, this might seem to contradict the expected 1/r behavior for the gradient near the edge of a thin screen. An analysis is presented for the special case of perpendicular plane wave incidence onto a thin screen, which shows that the secondary edge source formulation does indeed lead to the expected behavior close to the edge of an ideal wedge.
Acoustic beam steering by light refraction: Illustration with directivity patterns of a tilted volume photoacoustic source
Authors: Raetz Samuel , Dehoux Thomas , Perton Mathieu , Audoin Bertrand
Published: December 2013

The symmetry of a thermoelastic source resulting from laser absorption can be broken when the direction of light propagation in an elastic half-space is inclined relatively to the surface. This leads to an asymmetry of the directivity patterns of both compressional and shear acoustic waves. In contrast to classical surface acoustic sources, the tunable volume source allows one to take advantage of the mode conversion at the surface to control the directivity of specific modes. Physical interpretations of the evolution of the directivity patterns with the increasing light angle of incidence and of the relations between the preferential directions of compressional- and shear-wave emission are proposed. In order to compare calculated directivity patterns with measurements of normal displacement amplitudes performed on plates, a procedure is proposed to transform the directivity patterns into pseudo-directivity patterns representative of the experimental conditions. The comparison of the theoretical with measured pseudo-directivity patterns demonstrates the ability to enhance bulk-wave amplitudes and to steer specific bulk acoustic modes by adequately tuning light refraction.
Prediction of a body's structural impedance and scattering properties using correlation of random noise
Authors: Rakotonarivo Sandrine T. , Kuperman W. A. , Williams Earl G.
Published: December 2013

This paper derives a method to estimate the structural or surface impedance matrix (or equivalently the inverse of the structural Green's function) for an elastic body by placing it in an encompassing and spatially random noise field and cross-correlating pressure and normal velocity measurements taken on its surface. A numerical experiment is presented that utilizes a cross-correlation method to determine the structural impedance matrix for an infinite cylindrical shell excited by a spatially random noise field. It is shown that the correlation method produces the exact analytic form of the structural impedance matrix. Furthermore, using standard impedance formulations of the scattered and incident pressure fields at the object surface that are based on the equivalent source method and using this estimated structural impedance, a prediction of the scattered acoustic field at any position outside of the object can be made for any given incident field. An example is presented for a point (line) source near a cylindrical shell and when compared with the analytical result, excellent agreement is found between the scattered fields at a radius close to the shell.

DNA Damage Repair

In human cancers, oncogene activation interferes with DNA replication, leading to DNA replication stress and DNA double-strand breaks (DSBs).

Costantino
et al.

(p.
88
, published online 5 December) identified two subunits of DNA polymerase delta, POL3 and POL4, as critical for survival of DNA replication stress in human cells. Both subunits were required for break-induced replication (BIR), which is required to repair a specific type of DSB, with both subunits possibly required for processive DNA synthesis in BIR. Tandem head-to-tail duplications and fold-back inversions were seen in replication-stressed cells, similar to those seen in human breast and ovarian cancers, suggesting that BIR is important for repairing damaged forks in cancer cells.

An introduction to Canada’s boreal zone: ecosystem processes, health, sustainability, and environmental issues
Authors: Brandt J.P. , Flannigan M.D. , Maynard D.G. , Thompson I.D. , Volney W.J.A.
Published: December 2013

The boreal zone and its ecosystems provide numerous provisioning, regulating, cultural, and supporting services. Because of its resources and its hydroelectric potential, Canada’s boreal zone is important to the country’s resource-based economy. The region presently occupied by Canada’s boreal zone has experienced dramatic changes during the past 3 million years as the climate cooled and repeated glaciations affected both the biota and the landscape. For about the past 7000 years, climate, fire, insects, diseases, and their interactions have been the most important natural drivers of boreal ecosystem dynamics, including rejuvenation, biogeochemical cycling, maintenance of productivity, and landscape variability. Layered upon natural drivers are changes increasingly caused by people and development and those related to human-caused climate change. Effects of these agents vary spatially and temporally, and, as global population increases, the demands and impacts on ecosystems will likely increase. Understanding how humans directly affect terrestrial and aquatic ecosystems in Canada’s boreal zone and how these effects and actions interact with natural disturbance agents is a prerequisite for informed and adaptive decisions about management of natural resources, while maintaining the economy and environment upon which humans depend. This paper reports on the genesis and present condition of the boreal zone and its ecosystems and sets the context for a detailed scientific investigation in subsequent papers published in this journal on several key aspects: carbon in boreal forests; climate change consequences, adaptation, and mitigation; nutrient and elemental cycling; protected areas; status, impacts, and risks of non-native species; factors affecting sustainable timber harvest levels; terrestrial and aquatic biodiversity; and water and wetland resources.
EFFECTS OF DEFECTS AND ANHARMONICITY ON dx2-y2 WAVE PAIRING SYMMETRY IN CUPRATES
Authors: ASHOKAN VINOD , INDU B. D.
Published: December 2013

In this paper, the renormalized frequency spectrum and one-particle spectral function of a high temperature superconductor (HTS) is studied using double time thermodynamic Green's function approach via a newly formulated Hamiltonian (without considering BCS type Hamiltonian) which includes the effects of electron–phonon interactions, anharmonicities and that of isotopic impurities. It is investigated that the renormalized frequency further invokes the appearance of energy gap and functional dependence of dx2-y2 wave pairing in the superconducting state in cuprates. The salient feature of the present theory is the electron–phonon interaction in the vicinity of the impurity atoms reveals four-fold symmetric quasiparticle "cloud" aligned with the nodes of d-wave superconducting gap, which is believed to characterize superconductivity in high temperature superconducting materials. It has been further inferred that, a modest contribution of anharmonicity can also induce superconductivity.
Excess Early Mortality in Schizophrenia
Authors: Laursen Thomas Munk , Nordentoft Merete , Mortensen Preben Bo
Published: December 2013

Schizophrenia is often referred to as one of the most severe mental disorders, primarily because of the very high mortality rates of those with the disorder. This article reviews the literature on excess early mortality in persons with schizophrenia and suggests reasons for the high mortality as well as possible ways to reduce it. Persons with schizophrenia have an exceptionally short life expectancy. High mortality is found in all age groups, resulting in a life expectancy of approximately 20 years below that of the general population. Evidence suggests that persons with schizophrenia may not have seen the same improvement in life expectancy as the general population during the past decades. Thus, the mortality gap not only persists but may actually have increased. The most urgent research agenda concerns primary candidates for modifiable risk factors contributing to this excess mortality, i.e., side effects of treatment and lifestyle factors, as well as sufficient prevention and treatment of physical comorbidity.
Exploratory Structural Equation Modeling: An Integration of the Best Features of Exploratory and Confirmatory Factor Analysis
Authors: Marsh Herbert W. , Morin Alexandre J.S. , Parker Philip D. , Kaur Gurvinder
Published: December 2013

Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), path analysis, and structural equation modeling (SEM) have long histories in clinical research. Although CFA has largely superseded EFA, CFAs of multidimensional constructs typically fail to meet standards of good measurement: goodness of fit, measurement invariance, lack of differential item functioning, and well-differentiated factors in support of discriminant validity. Part of the problem is undue reliance on overly restrictive CFAs in which each item loads on only one factor. Exploratory SEM (ESEM), an overarching integration of the best aspects of CFA/SEM and traditional EFA, provides confirmatory tests of a priori factor structures, relations between latent factors and multigroup/multioccasion tests of full (mean structure) measurement invariance. It incorporates all combinations of CFA factors, ESEM factors, covariates, grouping/multiple-indicator multiple-cause (MIMIC) variables, latent growth, and complex structures that typically have required CFA/SEM. ESEM has broad applicability to clinical studies that are not appropriately addressed either by traditional EFA or CFA/SEM.
Vascular endothelial function and oxidative stress are related to dietary niacin intake among healthy middle-aged and older adults
Authors: Kaplon Rachelle E. , Gano Lindsey B. , Seals Douglas R.
Published: December 2013

We tested the hypothesis that vascular endothelial function and oxidative stress are related to dietary niacin intake among healthy middle-aged and older adults. In 127 men and women aged 48–77 yr, brachial artery flow-mediated dilation (FMD) was positively related to dietary niacin intake [%change (Δ): r = 0.20, P < 0.05; mmΔ: r = 0.25, P < 0.01]. In subjects with above-average dietary niacin intake (≥22 mg/day, NHANES III), FMD was 25% greater than in subjects with below-average intake ( P < 0.05). Stepwise linear regression revealed that dietary niacin intake (above vs. below average) was an independent predictor of FMD (%Δ: β = 1.8; mmΔ: β = 0.05, both P < 0.05). Plasma oxidized low-density lipoprotein, a marker of systemic oxidative stress, was inversely related to niacin intake ( r = −0.23, P < 0.05) and was lower in subjects with above- vs. below-average niacin intake (48 ± 2 vs. 57 ± 2 mg/dl, P < 0.01). Intravenous infusion of the antioxidant vitamin C improved brachial FMD in subjects with below-average niacin intake ( P < 0.001, n = 33), but not above-average ( P > 0.05, n = 20). In endothelial cells sampled from the brachial artery of a subgroup, dietary niacin intake was inversely related to nitrotyrosine, a marker of peroxynitrite-mediated oxidative damage ( r = −0.30, P < 0.05, n = 55), and expression of the prooxidant enzyme, NADPH oxidase ( r = −0.44, P < 0.01, n = 37), and these markers were lower in subjects with above- vs. below-average niacin intake [nitrotyrosine: 0.39 ± 0.05 vs. 0.56 ± 0.07; NADPH oxidase: 0.38 ± 0.05 vs. 0.53 ± 0.05 (ratio to human umbilical vein endothelial cell control), both P < 0.05]. Our findings support the hypothesis that higher dietary niacin intake is associated with greater vascular endothelial function related to lower systemic and vascular oxidative stress among healthy middle-aged and older adults.
Effective Thermal Conductivity of Open Cell Polyurethane Foam Based on the Fractal Theory
Authors: Ankang Kan , Houde Han
Published: December 2013

Based on the fractal theory, the geometric structure inside an open cell polyurethane foam, which is widely used as adiabatic material, is illustrated. A simplified cell fractal model is created. In the model, the method of calculating the equivalent thermal conductivity of the porous foam is described and the fractal dimension is calculated. The mathematical formulas for the fractal equivalent thermal conductivity combined with gas and solid phase, for heat radiation equivalent thermal conductivity and for the total thermal conductivity, are deduced. However, the total effective heat flux is the summation of the heat conduction by the solid phase and the gas in pores, the radiation, and the convection between gas and solid phase. Fractal mathematical equation of effective thermal conductivity is derived with fractal dimension and vacancy porosity in the cell body. The calculated results have good agreement with the experimental data, and the difference is less than 5%. The main influencing factors are summarized. The research work is useful for the enhancement of adiabatic performance of foam materials and development of new materials.

The augmented electric field integral equation (A-EFIE) with charge neutrality enforcement provides a stable formulation to conquer low-frequency breakdown characteristic of conventional EFIE. It is augmented with additional charge unknowns through current continuity equation. The A-EFIE combined with the multilevel adaptive cross-approximation (MLACA) algorithm is developed to further reduce the memory requirement and computation time for analyzing electromagnetic problems. Numerical examples are given to demonstrate the accuracy and efficiency of the proposed method.

Published: December 2013

The effects of different heat treatment temperatures on the structure and magnetic properties of Nd-Fe-B nanocomposite permanent magnetic alloys with nominal composition of Nd9.4Pr0.6Fe74.5Co6B6Ga0.5Ti1.5C1.5have been investigated. The most practical method to produce nanostructured metallic materials is rapid solidification. Melt spinning with constant wheel speed ofV=40 m/s was employed to produce ribbons. As-spun ribbons were examined by using differential scanning calorimetry (DSC) and X-ray diffractometer (XRD) with Cu-kαradiation. The ribbons were annealed at different temperatures in order to extract the best magnetic properties. The XRD and electron microscopy technique results confirm that grains are in the size of less than 50 nm. In addition, optimum magnetic properties were obtained at 700°C annealed temperature.

Published: December 2013

Polypyrrole (PPy) was reinforced with reduced graphene oxide (RGO) and iron oxide to achieve electrochemical stability and enhancement. The ternary nanocomposite film was prepared using a facile one‐pot chronoamperometry approach, which is inexpensive and experimentally friendly. The field emission scanning electron microscopy (FESEM) image shows a layered morphology of the ternary nanocomposite film as opposed to the dendritic structure of PPy, suggesting hybridization of the three materials during electrodeposition. X‐ray diffraction (XRD) profile shows the presence of Fe2O3 in the ternary nanocomposite. Cyclic voltammetry (CV) analysis illustrates enhanced current for the nanocomposite by twofold and fourfold compared to its binary (PPy/RGO) and individual (PPy) counterparts, respectively. The ternary nanocomposite film exhibited excellent specific capacitance retention even after 200 cycles of charge/discharge.

Extracellular vesicles have emerged as important mediators of intercellular communication in cancer, including by conveying tumor-promoting microRNAs between cells, but their regulation is poorly understood. In this study, we report the findings of a comparative microRNA profiling and functional analysis in human glioblastoma that identifies miR-1 as an orchestrator of extracellular vesicle function and glioblastoma growth and invasion. Ectopic expression of miR-1 in glioblastoma cells blocked in vivo growth, neovascularization, and invasiveness. These effects were associated with a role for miR-1 in intercellular communication in the microenvironment mediated by extracellular vesicles released by cancer stem–like glioblastoma cells. An extracellular vesicle–dependent phenotype defined by glioblastoma invasion, neurosphere growth, and endothelial tube formation was mitigated by loading miR-1 into glioblastoma-derived extracellular vesicles. Protein cargo in extracellular vesicles was characterized to learn how miR-1 directed extracellular vesicle function. The mRNA encoding Annexin A2 (ANXA2), one of the most abundant proteins in glioblastoma-derived extracellular vesicles, was found to be a direct target of miR-1 control. In addition, extracellular vesicle–derived miR-1 along with other ANXA2 extracellular vesicle networking partners targeted multiple pro-oncogenic signals in cells within the glioblastoma microenvironment. Together, our results showed how extracellular vesicle signaling promotes the malignant character of glioblastoma and how ectopic expression of miR-1 can mitigate this character, with possible implications for how to develop a unique miRNA-based therapy for glioblastoma management.

Published: December 2013

Este trabalho se propõe a traçar alguns caminhos percorridos pela fortuna crítica de Emily Dickinson, partindo as primeiras publicações de seus poemas, na década de 1890, até as propostas de estudos atuais, com enfoque na abordagem da crítica literária feminista norte-americana que desde a década de 1970 tem se afirmado como uma das possibilidades de leitura mais férteis para a compreensão da obra de Emily Dickinson. Este trabalho é fruto de uma pesquisa mais extensa sobre a poesia dickinsoniana em sua relação com questões envolvendo a autoria feminina.
Marcus Vinícius Faustini e a produção literária da biografia
Authors: Delgado Gabriel Estides
Published: December 2013

Em Guia afetivo da periferia, Marcus Vinícius Faustini lança mão de expedientes narrativos “literarizantes” para construir o relato de sua juventude como morador da Zona Oeste do Rio de Janeiro. A partir da identificação das contingências materiais que conformam a experiência sensível do autobiografado, esta análise, ao tomar o conceito de mimesis na literatura como representação interessada e produtiva, busca identificar no texto de Faustini o tratamento original dado às referências extralinguísticas. Ao não reconhecer servilmente o elemento prévio do qual parte, mas, ao mesmo tempo, assumindo-o como ponto fundante da condição de seu relato, o escritor concebe singular obra de ressignificação da experiência juvenil na periferia de uma grande cidade brasileira – ainda que para tanto deva servir-se de filiações culturais e estéticas convencionais.
A Imagem do pai em Lavoura Arcaica
Authors: Almeida-Abi Fabiana Rached de
Published: December 2013

A intenção deste trabalho é discutir algumas das construções das imagens do pai e do filho, a partir do romance Lavoura Arcaica (1975), de Raduan Nassar, no filme homônimo LavourArcaica (2001), de Luiz Fernando Carvalho. Para tanto, valemo-nos de alguns conceitos da psicanálise de Freud e de Lacan a respeito da idéia de ‘pai’. E, perpassando por alguns destes conceitos para o romance, tentamos entender como o desejo do filho se dá através do desejo do pai, constituindo-se esse desejo um elemento organizador da obra. Em outro aspecto, estudamos como as imagens do pai e do filho foram traduzidas nofilme homônimo LavourArcaica (2001), de Luiz Fernando Carvalho, em determinados planos, por meio dos movimentos de câmera, numa espécie de edificação e destruição das personagens, e também como algumas imagens bíblicas podem ter sido inscritas no filme através de uma aproximação com uma pintura de Caravaggio. Nas duas obras, em algum momento, os sentidos em torno das relações parentais estabelecidas são tão trabalhados, bem escritos, posicionados com esmero ao longo dos dois discursos, que passam a ser extravasados e há um retorno à forma que subjaz o sagrado, à essência da idéia de autoridade, à estrutura da hierarquia em si.

A Paixão dos Amantes: Separação e Superação em "Os Sapatinhos Vermelhos" e "Sem Ana, Blues", de Caio Fernando Abreu
Authors: Souza Thais Torres de
Published: December 2013

O artigo tem o objetivo de analisar dois contos do livro Os dragões não conhecem o Paraíso, de Caio Fernando Abreu que apresentam a temática da separação dos amantes: “Os Sapatinhos Vermelhos” e “Sem Ana, Blues”. Abandonadas, as personagens buscam superar a separação e, com isso, reconstituírem-se como sujeitos. Aparentemente, há diferenças entre a vingança realizada pela personagem de “Os Sapatinhos Vermelhos” e o modo como o narrador de “Sem Ana, Blues” se esquece daquela que o abandonou. No entanto, tendo como base o texto “Luto e Melancolia” de Freud e o livro A Separação dos Amantes, de Caruso, é possível observar também na atitude de extrema devoção do personagem de “Sem Ana, Blues” uma tentativa de realizar uma vingança e, com ela, tentar superar o abandono. Os contos comprovam que a concepção que Abreu apresenta do erotismo neste livro está fundamentada, sobretudo, no fato da sexualidade sustentar-se no conflito, tendo como consequência a eterna insatisfação dos amantes. Este modo de compreender o conceito de erotismo encontra ecos no pensamento de Bataille, para quem a sexualidade só pode se concretizar através da ruptura entre os amantes na busca pela realização de seus desejos.
A Estética da Culpa e a Sombra da Tradição: Notas para a análise de A queda, de Albert Camus
Authors: Araújo Raphael Luiz
Published: December 2013

Este texto pretende fazer uma introdução ao livro A queda, de Albert Camus, levando em conta considerações suscitadas por Jacquéline Lévi-Valensi e Anne Coudreuse, duas especialistas da obra. Escrita nos primeiros anos do pós-guerra, A queda se constitui como um monólogo híbrido que se subdivide em encenações teatrais, anedotas romanescas e máximas moralizantes. Essa estrutura adéqua-se inteiramente à concepção ideológica da obra, que busca questionar os discursos tradicionais, revelando a decadência do sentido atribuído à linguagem. A derrocada dos valores humanos reflete-se no protagonista por meio da sua hipocrisia — oscilante entre maldade e culpabilidade — que o leva a dividir-se em confissões duplas, pois também são acusações. Indiretamente, tal postura remete-se ao intertexto baudelairiano, que por meio do conceito do riso, é capaz de sintetizar essa denúncia ao julgamento universal.PALAVRAS-CHAVE:
Aqui tem coisa: Georges Perec e a Arte Contemporânea
Authors: Speranzini Manlio
Published: December 2013

O texto explora a relação da obra do escritor francês Georges Perec (1936 – 1982) com a Arte Contemporânea por meio do seu livro Les Choses – une histoire des années soixante, e da obra Gathering de Daniel Firman (1966), apresentada na exposição “regarde de tous tes yeux, regarde”, l’art contemporain de Georges Perec. Busca-se assim o entendimento do campo de atrações mútuas dessas obras por meio de certo ‘valor fotográfico’ capaz de ‘tornar visível o que não é necessariamente da ordem do visível’; pelo foco no desimportante na relação com o cotidiano; e por um tipo de construção expressiva que explicitaria o vazio e a falta de sentido nas relações do indivíduo com as coisas do mundo.

Authors: Souza Jr. Paulo Sérgio de
Published: December 2013

A obra de Vladímir Maiakóvski, entremeada de grandezas e engrandecida ao longo das décadas por seu poder de comoção social, apresenta um ponto-cego que, acreditamos, não pode ser deixado de lado — embora tenha sido em grande parte ignorado, em prol da imagem de força e bravura que interessaram, sobretudo, ao Regime. Assim, palavras como ‘futuro’ e ‘quotidiano’ — que, em sua obra, têm a força de conceitos —, quando levadas a sério, permitem que depreendamos a forte e ambígua relação do poeta com a necessidade de rompimento com a tradição, da qual, para ele, dependiam tanto a política quanto o amor, além da própria poesia. Trabalhar com essa dimensão de sua obra é procurar, atrás do mito criado por um governo, a dimensão de uma  escrita que se ateve à tentativa de fugir da mera repetição do passado, encontrando nessa busca os seus limites.

Este artigo analisa a ligação entre espaço urbano e diversidade sexual em dois contos brasileiros contemporâneos: “Triunfo dos pelos”, de Aretusa Von, e “Mi Buenos Aires querido”, de Cíntia Moscovich. As duas narrativas problematizam a relação espaço/gênero na medida em que denunciam e subvertem a natureza gendrada dos espaços geográficos e discursivos. Além disso, esboçam uma espécie de espaço queer, pelo questionamento da heterossexualidade compulsória e pela desconstrução dos binarismos que hierarquizam a sociedade contemporânea.

Por meio da discussão de alguns aspectos referentes aos estudos autobiográficos, às reflexões da estética da recepção e da teoria mimética de René Girard, propõe-se uma reflexão acerca da relação que pode haver entre um leitor ativo e o escritor. Além disso, propõe-se analisar de que forma a impressão de um relato autobiográfico permite uma reconfiguração da relação entre leitor e autor, gerando a possibilidade do estabelecimento entre eles de uma relação mimética.
Robust Subspace Discovery via Relaxed Rank Minimization

Published: December 2013

This letter examines the problem of robust subspace discovery from input data samples (instances) in the presence of overwhelming outliers and corruptions. A typical example is the case where we are given a set of images; each image contains, for example, a face at an unknown location of an unknown size; our goal is to identify or detect the face in the image and simultaneously learn its model. We employ a simple generative subspace model and propose a new formulation to simultaneously infer the label information and learn the model using low-rank optimization. Solving this problem enables us to simultaneously identify the ownership of instances to the subspace and learn the corresponding subspace model. We give an efficient and effective algorithm based on the alternating direction method of multipliers and provide extensive simulations and experiments to verify the effectiveness of our method. The proposed scheme can also be used to tackle many related high-dimensional combinatorial selection problems.
Noise-Robust Speech Recognition Through Auditory Feature Detection and Spike Sequence Decoding

Published: December 2013

Speech recognition in noisy conditions is a major challenge for computer systems, but the human brain performs it routinely and accurately. Automatic speech recognition (ASR) systems that are inspired by neuroscience can potentially bridge the performance gap between humans and machines. We present a system for noise-robust isolated word recognition that works by decoding sequences of spikes from a population of simulated auditory feature-detecting neurons. Each neuron is trained to respond selectively to a brief spectrotemporal pattern, or feature, drawn from the simulated auditory nerve response to speech. The neural population conveys the time-dependent structure of a sound by its sequence of spikes. We compare two methods for decoding the spike sequences—one using a hidden Markov model–based recognizer, the other using a novel template-based recognition scheme. In the latter case, words are recognized by comparing their spike sequences to template sequences obtained from clean training data, using a similarity measure based on the length of the longest common sub-sequence. Using isolated spoken digits from the AURORA-2 database, we show that our combined system outperforms a state-of-the-art robust speech recognizer at low signal-to-noise ratios. Both the spike-based encoding scheme and the template-based decoding offer gains in noise robustness over traditional speech recognition methods. Our system highlights potential advantages of spike-based acoustic coding and provides a biologically motivated framework for robust ASR development.
An Avowal of Prior Scepticism Enhances the Credibility of an Account of a Paranormal Event
Authors: Stone Anna
Published: December 2013

Wooffitt suggested that a narrator may enhance the plausibility of an account of an ostensibly paranormal event by making an avowal of prior scepticism but empirical support to date is lacking. In Experiment 1, participants read a first-person narrated scenario implicitly suggesting either telepathy or precognition as a causal explanation, then answered questions about the event and the narrator. The causal attribution to telepathy/precognition was stronger if the narrator took a position of prior scepticism compared to prior belief. This finding was reversed in Experiment 2 in which participants were pre-warned about the technique; the causal attribution to telepathy/precognition was stronger if the narrator declared prior belief. For a female narrator, but not male, a prior believer was perceived as more gullible than a prior sceptic. It appears that people may assume some truth in the avowal of prior scepticism unless encouraged to see it as a manipulative device.
When the Recipe Is More Important Than the Ingredients

Service innovation is a primary source of competitive advantage and a research priority. However, empirical evidence about the impact of innovativeness on new service adoption is inconclusive. A plausible explanation is that service innovation has thus far been studied using new product frameworks that do not fully capture the complexity of new service assessments by customers. We propose a different, holistic framework, which posits that new service adoption does not depend on individual service attributes, but on specific configurations of such attributes. We investigate this framework in a luxury hotel service context, using qualitative comparative analysis, a set-membership technique that is new to service research and suitable for configuration analyses. Results confirm that individual service attributes have complex trade-off effects and that only specific combinations of attributes act as sufficient conditions for new service adoption. Moreover, the composition of such combinations differs according to the different coproduction requirements. Our findings contribute to managerial practice by providing new insights for improving the service-development process and the launch strategy for new services. They also augment extant service knowledge by demonstrating why interdependencies among various innovation attributes are important to consider for gaining an accurate understanding of new service adoption.

Acute spinal cord injury leaves patients severely impaired and generates high levels of psychological distress among them and their families, which can cause a less active role in rehabilitation, worse functional recovery, and less perceived satisfaction with the results. Additionally, rehabilitation professionals who deal with this psychological distress could ultimately experience higher stress and more risk of burnout. This article presents the study protocol of the ESPELMA project, aimed to train rehabilitation professionals in the clinical management of acute spinal cord injury–associated psychological distress, and to measure the impact of this training on the patients’ perceived satisfaction with treatment.
Helicobacter pylori and mucosa-associated lymphoid tissue: what's new
Authors: Kuo Sung-Hsin , Cheng Ann-Lii
Published: December 2013

Low-grade mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach, gastric MALT lymphoma, is associated with Helicobacter pylori infection. The eradication of H pylori using antibiotics is successful in 60% to 80% of affected patients. In contrast to the previous paradigm, we and other investigators have shown that a certain proportion of patients with H pylori–positive early-stage diffuse large B-cell lymphoma (DLBCL) of the stomach with histological evidence of MALT lymphoma, including high-grade transformed gastric MALT lymphoma and gastric DLBCL(MALT), achieved long-term complete pathological remission (pCR) after first-line H pylori eradication therapy, indicating that the loss of H pylori dependence and high-grade transformation are separate events in the progression of gastric lymphoma. In addition, patients with H pylori–positive gastric DLBCL without histological evidence of MALT (gastric pure DLBCL) may also respond to H pylori eradication therapy. A long-term follow-up study showed that patients who achieved pCR remained lymphoma free. Gastric MALT lymphoma is indirectly influenced by H pylori infection through T-cell stimulation, and recent studies have shown that H pylori–triggering chemokines and their receptors, H pylori–associated epigenetic changes, H pylori–regulated miRNA expression, and tumor infiltration by CD4+CD25+ regulatory T cells contribute to lymphomagenesis of gastric MALT lymphoma. Recent studies have also demonstrated that the translocation of CagA into B lymphocytes inhibits apoptosis through p53 accumulation, BAD phosphorylation, and the up-regulation of Bcl-2 and Bcl-XL expression. In gastric MALT lymphoma, CagA may stimulate lymphomagenesis directly, through the regulation of signal transduction, and intracellular CagA is associated with H pylori dependence. These findings represent a substantial paradigm shift compared with the classical theory of H pylori–reactive T cells contributing indirectly to the development of MALT lymphoma. In conclusion, a wide range of H pylori–related gastric lymphomas have been identified. The use of antibiotics as the sole first-line therapy for early-stage gastric pure DLBCL requires validation in a prospective study. The clinical and biological significance of the CagA oncoprotein in the lymphomagenesis of gastric MALT lymphoma warrants further study.
Treatment of older patients with chronic lymphocytic leukemia: key questions and current answers
Authors: Shanafelt Tait
Published: December 2013

Despite the advanced age at onset, chronic lymphocytic leukemia (CLL) shortens the life expectancy of the majority of newly diagnosed patients. The management of elderly patients with CLL is more complex than that of younger patients due to the greater frequency of comorbidities and functional impairment as well as reduced organ function. Many of the recent advances in the care of CLL patients (prognostication, more intense combination therapy regimens) are of unclear relevance for elderly patients. This review addresses 5 key questions in the management of elderly patients with CLL: (1) why is classifying the “fitness” of CLL patients necessary; (2) what criteria should be used to classify patient fitness; (3) when should elderly patients be treated; (4) how should therapy be selected for elderly patients; and (5) which therapy is best (for this patient)?
Alternative approaches to eradicating the malignant clone in chronic myeloid leukemia: tyrosine-kinase inhibitor combinations and beyond
Authors: Ahmed Wesam , Van Etten Richard A.
Published: December 2013

In patients with chronic myeloid leukemia (CML) in chronic phase who have achieved complete molecular remission on imatinib therapy, clinical trials from France and Australia have demonstrated that the majority experience prompt molecular relapse of their leukemia upon discontinuation of the drug, showing that long-term monotherapy with tyrosine kinase inhibitors is not curative in the majority of patients with CML. This has focused attention on strategies to eradicate residual disease in CML that is presumed to arise from malignant Ph+ stem cells, which should result in permanent cure and long-term leukemia-free survival. Here, we review the evidence that targeting CML stem cells will be of clinical benefit and discuss pharmacological and immunological approaches to accomplish this goal. Where possible, we link preclinical studies of CML stem cell biology to emerging results from clinical trials of agents that may target these cells.
von Willebrand disease: advances in pathogenetic understanding, diagnosis, and therapy
Authors: Lillicrap David
Published: December 2013

von Willebrand disease (VWD) is the most common autosomally inherited bleeding disorder. The disease represents a range of quantitative and qualitative pathologies of the adhesive glycoprotein von Willebrand factor (VWF). The pathogenic mechanisms responsible for the type 2 qualitative variants of VWF are now well characterized, with most mutations representing missense substitutions influencing VWF multimer structure and interactions with platelet GPIbα and collagen and with factor VIII. The molecular pathology of type 3 VWD has been similarly well characterized, with an array of different mutation types producing either a null phenotype or the production of VWF that is not secreted. In contrast, the pathogenetic mechanisms responsible for type 1 VWD remain only partially resolved. In the hemostasis laboratory, the measurement of VWF:Ag and VWF:RCo are key components in the diagnostic algorithm for VWD, although the introduction of direct GPIbα-binding assays may become the functional assay of choice. Molecular genetic testing can provide additional benefit, but its utility is currently limited to type 2 and 3 VWD. The treatment of bleeding in VWD involves the use of desmopressin and plasma-derived VWF concentrates and a variety of adjunctive agents. Finally, a new recombinant VWF concentrate has just completed clinical trial evaluation and has demonstrated excellent hemostatic efficacy and safety.
Molecular approaches for improved clotting factors for hemophilia
Authors: Kaufman Randal J. , Powell Jerry S.
Published: December 2013

Hemophilia is caused by a functional deficiency of one of the coagulation proteins. Therapy for no other group of genetic diseases has seen the progress that has been made for hemophilia over the past 40 years, from a life expectancy in 1970 of ∼ 20 years for a boy born with severe hemophilia to essentially a normal life expectancy in 2013 with current prophylaxis therapy. However, these therapies are expensive and require IV infusions 3 to 4 times each week. These are exciting times for hemophilia because several new technologies that promise extended half-lives for factor products, with potential for improvements in quality of life for persons with hemophilia, are in late-phase clinical development.
