Published: April 2012

AbstractNest predation is a major limiting factor for songbird productivity, including the federally endangered black‐capped vireo (Vireo atricapilla). However, nest predator information is limited across the range of the black‐capped vireo in central and southwest Texas. We monitored nests in 3 counties within the breeding range of black‐capped vireos in Texas in 2008 and 2009 and used continuous recording digital video cameras to record predation events. We video‐monitored 115 nests and documented 39 predation events by at least 9 predator species. Overall, we observed avian species (51%, n = 39), specifically brown‐headed cowbirds (Molothrus ater; n = 12), and snakes (26%, n = 39) as the most frequent nest predators. The estimated daily nest survival rate during the laying and incubation stage was 0.985 (95% CI = 0.967–0.993) and 0.944 (95% CI = 0.921–0.961) during the nestling stage. In addition, we analyzed models of predator‐specific nest predation using multinomial logistic regression. Effect of nest height on predation rate was significant for snakes; nest stage was significant for nests depredated by avian predators. By identifying and increasing our knowledge of nest predators and vegetation characteristics associated with greater risk of predation in multiple locations within the black‐capped vireo's range, we can effectively manage habitat to benefit recovery efforts of the species. © 2012 The Wildlife Society.

“It's not Easy Being Green”: Exploring Green Creeds, Green Deeds, and Internal Environmental Locus of Control
Authors: Cleveland Mark , Kalamas Maria , Laroche Michel 
Published: April 2012

ABSTRACTThe authors report on the development of a novel construct, internal environmental locus of control (INELOC), which captures consumers’ multifaceted attitudes pertaining to personal responsibility towards and ability to affect environmental outcomes. Using data gathered from a sample of consumers, the linkages between INELOC and a wide array of environmental behaviors were investigated. Exploratory and confirmatory factor analyses revealed four first‐order dimensions (“green consumer,” “activism,” “advocate,” and “recycling attitudes”) embedded within a second‐order INELOC factor. Structural equations modeling techniques showed that INELOC was a strong positive predictor of many behaviors. However, the nature of the attitude–behavior relationship varied considerably across behavioral contexts, implying that people do not consistently behave in a proenvironmental manner. © 2012 Wiley Periodicals, Inc.

Published: April 2012

AbstractBackground and aimFor tailored implementation of evidence‐based recommendations and guidelines on physical therapy in patients with rheumatoid arthritis (RA), insight into current physical therapy practice is needed.MethodTwo hundred and fifty general physical therapists and 211 specialized physical therapists with advanced arthritis training were sent a questionnaire to assess the frequency with which they applied a set of assessments (n = 10) and interventions (n = 7) included in a Dutch physical therapy guideline for RA. Differences between general and specialist physical therapists were analysed using Student's t‐tests or chi‐square tests where appropriate.ResultsIn total, 233 physical therapists (51%) responded. Of these, 96 (41%) had completed an additional arthritis course and were designated as specialist physical therapists. Among the physical therapists who returned the questionnaire, 69% (or more) reported that they ‘always’ assessed limitations in daily functioning, pain, morning stiffness, muscle strength, joint range of motion, joint stability, gait and limitations in leisure activities as part of their initial assessment, and 37% and 48% reported ‘always’ to assess aerobic capacity and limitations in work situations, respectively. Concerning interventions, exercise therapy and education were ‘always’ applied by 70% and 68% of the responders, respectively. Only a minority of responders reported ‘always’ applying ultrasound, electrical stimulation, heat therapy, massage and passive mobilizations (0%, 0%, 5%, 5% and 14%, respectively). Apart from aerobic capacity and work limitations, all other assessments were reported as ‘always’ applied by significantly (p < 0.05) more specialist physical therapists than general physical therapists. Regarding interventions, significantly more specialist physical therapists reported that they ‘always’ applied exercise therapy and education. Significantly fewer specialist physical therapists than in the general group reported ‘always’ using heat therapy, massage and mobilizations (p < 0.05).ConclusionThe majority of physical therapists reported that they ‘always’ applied most of the assessments and interventions recommended in a Dutch physical therapy guideline for the management of RA. Areas for improvement include the assessment of aerobic capacity and work limitations. The observed differences between specialist and general physical therapists support the added value of advanced arthritis courses. Copyright © 2012 John Wiley & Sons, Ltd.
Thermo‐hydro‐mechanical modeling of fluid geological storage by Godunov‐mixed methods
Authors: Castelletto N. , Ferronato M. , Gambolati G. 
Published: April 2012

SUMMARYThe efficient solution to the coupled system of PDEs governing the mass and the energy balance in deformable porous media requires advanced numerical algorithms. A combination of mixed/Galerkin finite elements and finite volumes along with a staggered method are employed. Fluid flow and heat transfer are addressed iteratively by a fully coupled approach and the medium deformation by an explicitly coupled scheme, at each time step. Such formulation allows for stable numerical solutions, element‐wise conservative velocity fields and accurate prediction of sharp temperature convective fronts. The proposed model is experimented with in realistic applications of a deep aquifer fluid injection. Copyright © 2012 John Wiley & Sons, Ltd.

Published: April 2012

AbstractAcute lymphoblastic leukemia (ALL) is the most common type of pediatric neoplasia. Highly heterogeneous, ALL includes several genetic subtypes with varying clinical outcome. Although, some features are well established as prognostic predictors, the details of the molecular mechanisms underlying different phenotypes are only beginning to emerge. Recently, microRNAs (miRNAs) have been shown to influence a range of physiological processes and, consequently, alterations in their expression and functions have been associated with the development of many cancers, including leukemia. This article aims to review the current state of knowledge of the role of miRNAs on the biology of childhood ALL, also including relevant findings from the adult leukemia literature.

pH‐responsive hydrogels with dispersed hydrophobic nanoparticles for the delivery of hydrophobic therapeutic agents
Authors: Schoener Cody A , Hutson Heather N , Peppas Nicholas A 
Published: April 2012

AbstractTo investigate the delivery of hydrophobic therapeutic agents, a new class of polymer carriers was synthesized. These carriers are composed of two components: (i) a pH‐responsive hydrogel composed of methacrylic acid grafted with poly(ethylene glycol) tethers, P(MAA‐g‐EG), and (ii) hydrophobic poly(methyl methacrylate) (PMMA) nanoparticles. Before the P(MAA‐g‐EG) hydrogel was crosslinked, PMMA nanoparticles were added to the solution and upon exposure to UV light they were photoencapsulated throughout the P(MAA‐g‐EG) hydrogel structure. The pH‐responsive behavior of P(MAA‐g‐EG) is capable of triggered release of a loaded therapeutic agent, such as a low molecular weight drug or protein, when it passes from the stomach (low pH) to upper small intestine (neutral pH). The introduction of PMMA nanoparticles into the hydrogel structure affected the swelling behavior, therapeutic agent loading efficiency, and solute release profiles. In equilibrium swelling conditions the swelling ratio of nanoparticle‐containing hydrogels decreased with increasing nanoparticle content. Loading efficiencies of the model therapeutic agent fluorescein ranged from 38% to 51% and increased with increasing hydrophobic content. Release studies from neat P(MAA‐g‐EG) and the ensuing P(MAA‐g‐EG) hydrogels containing nanoparticles indicated that the transition from low pH (2.0) to neutral pH (7.0) triggered fluorescein release. Maximum fluorescein release depended on the structure and hydrophobicity of the carriers used in these studies. Copyright © 2012 Society of Chemical Industry

Published: April 2012

AbstractIn the face of dwindling financial resources, educational leaders are looking to refine resource allocation while maintaining a focus on improved student outcomes. This article presents initial findings from a professional development state initiative called Effective Behavioral and Instructional Support Systems (EBISS). The EBISS initiative aims to teach practicing educators about two evidence‐based systems of practice and how to blend those practices for more efficient and effective school systems. The targeted systems are School‐Wide Positive Behavioral Interventions and Supports and School‐Wide Reading Model. Descriptive statistics from 140 participating elementary schools suggest there was an increase in (a) the administration of behavior and literacy screening tools, (b) the number of teams examining and analyzing these data, and (c) the implementation scores and student outcomes at selected grade levels. Continued exploration of data‐based collaboration in school buildings appears warranted. © 2012 Wiley Periodicals, Inc.

Tailoring electrical properties of (Na1/2K1/2)NbO3‐based lead‐free piezoelectric ceramics
Authors: Fang Bijun , Jiang Na , Ding Jianning 
Published: April 2012

AbstractOxide‐doped 0.94(Na1/2K1/2)NbO3‐0.03LiSbO3‐0.03LiTaO3 (NKN‐0.03LS‐0.03LT) lead‐free piezoelectric ceramics were prepared by the conventional solid‐state reaction method sintered under ambient pressure. The kind of oxide dopant and sintering temperature exert great influences on crystal structure, density, and electrical properties of the synthesized (Na1/2K1/2)NbO3‐based (NKN) ceramics. The addition of appropriate sintering additives can produce a liquid‐phase sintering mechanism in the NKN‐based ceramics, which will promote the development of grains and improve densification of the ceramics. Pure tetragonal perovskite structure oxide‐doped NKN‐0.03LS‐0.03LT ceramics can be prepared sintered in a narrow sintering temperature range. As compared to the undoped NKN‐0.03LS‐0.03LT ceramics, the oxide‐doped NKN‐0.03LS‐0.03LT ceramics sintered at the optimized sintering temperature exhibit rather large relative density, comparable dielectric and piezoelectric properties, and improved ferroelectric and electromechanical properties.
Significantly reduced leakage currents in organic thin film transistors with Mn‐doped Bi2Ti2O7 high‐k gate dielectrics

Published: April 2012

AbstractWe report the fabrication of organic thin‐film transistors (OTFTs) with high‐k gate dielectrics of Mn‐doped Bi2Ti2O7 (BTO) films. 3% Mn‐doped BTO films deposited on polymer substrates by pulsed laser deposition at room temperature exhibit low leakage currents of 2.1 × 10–8 A/cm2 at an applied electric field of 0.3 MV/cm, while undoped BTO films show much higher leakage currents of 4.3 × 10–4 A/cm2. Mn doping effectively reduces the number of oxygen vacancies in the films and improves the electrical properties. Low operation voltage and significantly reduced leakage currents are demonstrated in pentacene‐based OTFTs with the Mn‐doped BTO gate dielectrics. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Fast and effective soft links
Authors: Akinyemi John A. , Clarke Charles L. A. 
Published: April 2012

SUMMARYInspired by requirements traceability problems, we present a method for implementing fast and effective hypertext links to specific locations within documents. These soft links do not depend on tags, markup, or closed tool sets, yet they can generally survive extensive edits to a document collection, allowing the targets of these links to be located in real collections after years of ongoing and frequent changes. We base our implementation of soft links on an existing passage retrieval algorithm, originally designed for question answering. The method treats the text surrounding the target of a soft link as a passage to be retrieved, creates a signature for that passage, and resolves the link by searching for the passage. The method is evaluated over a large collection of text and two large collections of source code, one written in the C programming language and one written in Java.

Published: April 2012

AbstractObjectiveTo evaluate whether increasing body mass index (BMI) alters the efficacy of ultrasound‐directed cerclage in women with a history of preterm birth.MethodsThis was a planned secondary analysis of a multicenter trial in which women with a singleton gestation and prior spontaneous preterm birth (17 to 33 + 6 weeks' gestation) were screened for a short cervix by serial transvaginal ultrasound evaluations between 16 and 22 + 6 weeks. Women with a short cervix (cervical length < 25 mm) were randomly assigned to cerclage or not. Linear and logistic regression were used to assess the relationship between BMI and continuous and categorical variables, respectively.ResultsOverall, in the screened women (n = 986), BMI was not associated with cervical length (P = 0.68), gestational age at delivery (P = 0.12) or birth at < 35 weeks (P = 0.68). For the cerclage group (n = 148), BMI had no significant effect. For the no‐cerclage group (n = 153), BMI was associated with a decrease in gestational age at delivery, with an estimated slope of − 0.14 weeks per kg/m2 (P = 0.03; including adjustment for cervical length). This result was driven primarily by several women with BMI > 47 kg/m2.ConclusionIn women at high risk for recurrent preterm birth, BMI was not associated with cervical length or gestational age at birth. BMI did not appear to adversely affect ultrasound‐indicated cerclage. Copyright © 2012 ISUOG. Published by John Wiley & Sons, Ltd.
Gonad morphogenesis and distal tip cell migration in the Caenorhabditis elegans hermaphrodite
Authors: Wong Ming‐Ching , Schwarzbauer Jean E. 
Published: April 2012

AbstractCell migration and morphogenesis are key events in tissue development and organogenesis. In Caenorhabditis elegans, the migratory path of the distal tip cells determines the morphology of the hermaphroditic gonad. The distal tip cells undergo a series of migratory phases interspersed with turns to form the gonad. A wide variety of genes have been identified as crucial to this process, from genes that encode components and modifiers of the extracellular matrix to signaling proteins and transcriptional regulators. The connections between extracellular and transmembrane protein functions and intracellular pathways are essential for distal tip cell migration, and the integration of this information governs gonad morphogenesis and determines gonad size and shape.

In deprivierten Stadtvierteln kommt es zu einer wechselseitigen Verstärkung von individuellen und stadtteilbezogenen Benachteiligungen mit erheblichen Auswirkungen auf die gesundheitlichen Chancen der Bewohner. Hier müssen kommunale, gesundheitspolitische und lokale Strategien koordiniert werden. Stadtteilarbeit und Gesundheitsförderung sollen primär an den sozialen und strukturellen Verhältnissen in der Nachbarschaft ansetzen. Dafür eignen sich Strategien wie Partizipation, Arbeit mit Multiplikatoren, beiläufige Kompetenzvermittlung und Netzwerkbildung in besonderer Weise.
Validation of the Long-term Difficulties Inventory (LDI) and the List of Threatening Experiences (LTE) as measures of stress in epidemiological population-based cohort studies
Authors: Rosmalen J. G. M. , Bos E. H. , de Jonge P. 
Published: April 2012

BackgroundStress questionnaires are included in many epidemiological cohort studies but the psychometric characteristics of these questionnaires are largely unknown. The aim of this study was to describe these characteristics for two short questionnaires measuring the lifetime and past year occurrence of stress: the List of Threatening Events (LTE) as a measure of acute stress and the Long-term Difficulties Inventory (LDI) as a measure of chronic stress.MethodThis study was performed in a general population cohort consisting of 588 females (53.7%) and 506 males (46.3%), with a mean age of 53.5 years (s.d.=11.3 years). Respondents completed the LTE and the LDI for the past year, and for the age categories of 0–12, 13–18, 19–39, 40–60, and >60 years. They also completed questionnaires on perceived stress, psychological distress (the General Health Questionnaire, GHQ-12), anxiety and depression (the Symptom Checklist, SCL-8) and neuroticism (the Eysenck Personality Questionnaire – Revised Short Scale, EPQ-RSS-N). Approximately 2 years later, 976 respondents (89%) completed these questionnaires for a second time.ResultsThe stability of the retrospective reporting of long-term difficulties and life events was satisfactory: 0.7 for the lifetime LDI and 0.6 for the lifetime LTE scores. The construct validity of these lists is indicated by their positive associations with psychological distress, mental health problems and neuroticism.ConclusionsThis study in a large population-based sample shows that the LDI and LTE have sufficient validity and stability to include them in major epidemiological cohort studies.
Public men, private interests: the origins, structure and practice of police courts in Scotland, c.1800–1833
Authors: BARRIE DAVID G. , BROOMHALL SUSAN 
Published: April 2012

ABSTRACTThis article examines how civic tensions and the rise to prominence of a new class of businessmen contributed to the evolution of police courts in Scottish towns, c.1800 to 1833. It argues that men of property intertwined civic imperatives with their own moral and economic interests in order to effect reform and defend their position, status and influence. It also contends that police courts were important institutions in reflecting and exposing the divisions and shared interests that existed among ‘public men’ and the private interests they sought to promote and safeguard. In doing so, the article highlights social hierarchies – both between men of property and different classes – as an important force in shaping the development and institutional workings of police courts.
The city as a business: gas and business in the Spanish region of Galicia, 1850–1936
Authors: LÓPEZ ALBERTE MARTÍNEZ , MIRÁS-ARAUJO JESÚS 
Published: April 2012

ABSTRACTThe history of town gas is unique in the development of public services in urban areas. Indeed, gas was the subject of the first network infrastructure set up in cities. In Spain, its history is discontinuous because the networks were dismantled in the 1940s and 1950s. The purpose of this paper is to retrace the steps of the development of the gas network in a region where the Spanish gas companies took the form of early modern businesses. They contributed significantly to the dynamism of local financial markets, both in terms of enterprise configuration, technology dissemination and innovative management. However, the development of the gas industry remained subject to local conditions of supply and demand, to conflicts with local government and suffered from competition from electricity.
Power, accidents, and institutional changes: the case of a Chinese hospital in Hong Kong
Authors: MA SHU-YUN 
Published: April 2012

ABSTRACTIn response to the call for more investigation on ‘institutional dynamism’, this article examines the role of power and accidents in causing institutional changes, employing the theoretical perspective of historical institutionalism. The impact of two ‘accidents’ (epidemics) on the institutional setting of a hospital in Hong Kong under different power contexts (changes of political sovereignty) is analysed as a case study. The finding is that power matters more than accidents. This is not to deny the importance of accidents. Accidents matter because they produce windows of opportunity for institutional changes to take place. Through political manoeuvres powerful actors may decide which accidents should cause change.
