AbstractThe purpose of this study was to investigate the relationship between the osteoblastic cells behavior and biotribocorrosion phenomena on bioactive titanium (Ti). Ti substrates submitted to bioactive anodic oxidation and etching treatments were cultured up to 28 days with MG63 osteoblast‐like cells. Important parameters of in vitro bone‐like tissue formation were assessed. Although no major differences were observed between the surfaces topography (both rough) and wettability (both hydrophobic), a significant increase in cell attachment and differentiation was detected on the anodized substrates as product of favorable surface morphology and chemical composition. Alkaline phosphatase production has increased (≈20 nmol/min/mg of protein) on the anodized materials, while phosphate concentration has reached the double of the etched material and calcium production increased (over 20 µg/mL). The mechanical and biological stability of the anodic surfaces were also put to test through biotribocorrosion sliding solicitations, putting in evidence the resistance of the anodic layer and the cells capacity of regeneration after implant degradation. The Ti osteointegration abilities were also confirmed by the development of strong cell–biomaterial bonds at the interface, on both substrates. By combining the biological and mechanical results, the anodized Ti can be considered a viable option for dentistry. © 2014 Wiley Periodicals, Inc.

The Role of Account Length in Detecting Deception in Written and Orally Produced Autobiographical Accounts using Reality Monitoring
Authors: Elntib Stamatis , Wagstaff Graham F. , Wheatcroft Jacqueline M. 
Published: July 2014

AbstractReality monitoring lie‐detection studies, like others that use raw frequency counts as primary data, seem consistently to underestimate the influence of the length of (or number of words in) the account. The decisions as to whether to standardise or not, or what method of standardisation to use, are rarely empirically driven, so it is still unclear as to whether reality monitoring is more effective before or after standardisation for length. Another factor that also has received little attention in the reality monitoring literature is whether statements are produced orally or in written form. To investigate these issues, 42 autobiographical statements, 21 truthful, and 21 deceptive, including 22 oral and 20 written accounts, were analysed before and after word count standardisation. Results showed that reality monitoring criteria only discriminated significantly between truthful and deceptive accounts when no attempt to control for word count was made. Also, oral statements contained more evidence of reality monitoring criteria before standardisation for word count, whereas written statements were denser and contained more evidence of reality monitoring criteria after standardisation. Implications are discussed. Copyright © 2014 John Wiley & Sons, Ltd.
Rewards and employee creative performance: Moderating effects of creative self‐efficacy, reward importance, and locus of control
Authors: Malik Muhammad Abdur Rahman , Butt Arif N. , Choi Jin Nam 
Published: July 2014

SummaryThe effects of extrinsic rewards on creative performance have been controversial, and scholars have called for the examination of the boundary conditions of such effects. Drawing upon expectancy theory, we attend to both reinforcement and self‐determination pathways that reveal the informational and controlling functions of creativity‐related extrinsic rewards. We further identify the individual dispositions that moderate these two pathways. Specifically, we propose that extrinsic rewards for creativity positively predict creative performance only when employees have high creative self‐efficacy and regard such rewards as important. We likewise propose that extrinsic rewards positively affect the intrinsic motivation of employees with an internal locus of control, thus enhancing their creative performance. Results based on a sample of 181 employee–supervisor dyads largely supported these expectations. The current analysis enriches the creativity literature by combining different perspectives in a coherent framework, by demonstrating the positive effects of extrinsic rewards on intrinsic motivation, and by demonstrating that the rewards–creativity relationship varies across employees depending on their individual differences.

Employee judgments of and behaviors toward corporate social responsibility: A multi‐study investigation of direct, cascading, and moderating effects
Authors: Vlachos Pavlos A. , Panagopoulos Nikolaos G. , Rapp Adam A. 
Published: July 2014

SummaryDo employee judgments of their organization's corporate social responsibility (CSR) programs relate to CSR‐specific performance and in‐role job performance? Can middle managers influence the formation of such judgments and what factors might moderate such cascading influences? To answer these yet unaddressed questions, we conduct three studies. Study 1 takes an organizational justice perspective and tests our baseline model. Results show that employees' CSR judgments trigger their affective commitment and performance on extra‐role CSR‐specific behaviors; however, extra‐role CSR‐specific performance is unrelated to in‐role job performance. Study 2 replicates Study 1's findings while, in addition, applies a social information processing approach and offers novel insights by demonstrating the cascading effects of managers' CSR judgments on employee CSR judgments. Investments made in CSR programs in order to improve employee judgments and behaviors may be unsuccessful if employees' CSR judgments are based on social information that remains unchanged. In addition to replicating the findings from studies 1 and 2, study 3 draws from middle management involvement and leadership theories to show that leadership styles and managers' involvement in implementing deliberate strategy can strengthen or weaken these cascading effects. This highlights the important role of middle managers as “linking pins” in the CSR strategy implementation process. Copyright © 2014 John Wiley & Sons, Ltd.

Authors: Byers Brett A. , Temple‐Oberle Claire F. , Hurdle Valerie , McKinnon J. Greg 
Published: July 2014

AbstractBackgroundSeveral phase II studies have assessed intra‐lesional interleukin‐2 (IL‐2) for the treatment of in‐transit melanoma. This systematic review addresses the efficacy and side effect profile of IL‐2.MethodsMEDLINE, EMBASE, Cochrane Library, and Google Scholar databases were searched from 1980 to 2012 for studies evaluating the clinical response to IL‐2 for in‐transit melanoma. Titles and abstracts were screened by two independent researchers for suitability using predetermined inclusion and exclusion criteria. A modified quality assessment tool for observational studies was used. Data were pooled and analyzed to determine lesion and patient response rates.ResultsForty‐nine studies were identified. Forty‐three did not meet inclusion criteria, leaving six observational trials. Heterogeneity was seen in IL‐2 dosage and treatment interval. Response rate was variable as well. Overall, 2,182 lesions and 140 patients were treated in these six studies. Pooling the lesions, complete response was seen in 78%. Pooling subjects, 50% achieved a complete response. Treatment was generally well tolerated, with localized pain and swelling, and mild flu‐like symptoms. There were only three grade 3 adverse events reported, including rigors, headache, and fever with arthralgia.ConclusionsIntra‐lesional IL‐2 safely and effectively provides locoregional control of in‐transit melanoma.

Advances in functional and structural imaging of the human lung using proton MRI
Authors: Miller G. Wilson , Mugler John P. , Sá Rui C. , Altes Talissa A. , Prisk G. Kim , Hopkins Susan R. 
Published: July 2014

The field of proton lung MRI is advancing on a variety of fronts. In the realm of functional imaging, it is now possible to use arterial spin labeling (ASL) and oxygen‐enhanced imaging techniques to quantify regional perfusion and ventilation, respectively, in standard units of measurement. By combining these techniques into a single scan, it is also possible to quantify the local ventilation–perfusion ratio, which is the most important determinant of gas‐exchange efficiency in the lung. To demonstrate potential for accurate and meaningful measurements of lung function, this technique was used to study gravitational gradients of ventilation, perfusion, and ventilation–perfusion ratio in healthy subjects, yielding quantitative results consistent with expected regional variations.Such techniques can also be applied in the time domain, providing new tools for studying temporal dynamics of lung function. Temporal ASL measurements showed increased spatial–temporal heterogeneity of pulmonary blood flow in healthy subjects exposed to hypoxia, suggesting sensitivity to active control mechanisms such as hypoxic pulmonary vasoconstriction, and illustrating that to fully examine the factors that govern lung function it is necessary to consider temporal as well as spatial variability. Further development to increase spatial coverage and improve robustness would enhance the clinical applicability of these new functional imaging tools.In the realm of structural imaging, pulse sequence techniques such as ultrashort echo‐time radial k‐space acquisition, ultrafast steady‐state free precession, and imaging‐based diaphragm triggering can be combined to overcome the significant challenges associated with proton MRI in the lung, enabling high‐quality three‐dimensional imaging of the whole lung in a clinically reasonable scan time. Images of healthy and cystic fibrosis subjects using these techniques demonstrate substantial promise for non‐contrast pulmonary angiography and detailed depiction of airway disease. Although there is opportunity for further optimization, such approaches to structural lung imaging are ready for clinical testing. Copyright © 2014 John Wiley & Sons, Ltd.

Study ObjectiveAntipsychotic polypharmacy―the use of more than one antipsychotic concomitantly—has increased in children and adolescents and may be associated with increased adverse effects, nonadherence, and greater costs. Thus, we sought to examine the demographic and clinical characteristics of psychiatrically hospitalized children and adolescents who were prescribed antipsychotic polypharmacy and to identify predictors of this prescribing pattern.DesignRetrospective medical record review.SettingThe inpatient psychiatric unit of a large, acute care, urban children's hospital.PatientsOne thousand four hundred twenty‐seven children and adolescents who were consecutively admitted and discharged between September 2010 and May 2011.Measurements and Main ResultsAt discharge, 840 (58.9%) of the 1427 patients were prescribed one or more antipsychotics, and 99.3% of these received second‐generation antipsychotics. Of these 840 patients, 724 (86.2%) were treated with antipsychotic monotherapy, and 116 (13.8%) were treated with antipsychotic polypharmacy. Positive correlations with antipsychotic polypharmacy were observed for placement or custody outside the biological family; a greater number of previous psychiatric admissions; longer hospitalizations; admission for violence/aggression or psychosis; and intellectual disability, psychotic, disruptive behavior, or developmental disorder diagnoses. Negative correlations with antipsychotic polypharmacy included admission for suicidal ideation/attempt or depression, and mood disorder diagnoses. Significant predictors of antipsychotic polypharmacy included admission for violence or aggression (odds ratio [OR] 2.76 [95% confidence interval (CI) 1.36–5.61]), greater number of previous admissions (OR1.21 [95%CI1.10–1.33]), and longer hospitalizations (OR1.08 [95%CI1.04–1.12]). In addition, diagnoses of intellectual disability (OR2.62 [95%CI1.52–4.52]), psychotic disorders (OR5.60 [95%CI2.29–13.68]), and developmental disorders (OR3.18 [95%CI1.78–5.65]) were predictors of antipsychotic polypharmacy.ConclusionCertain youth may have a higher likelihood of being prescribed antipsychotic polypharmacy, which should prompt careful consideration of medication treatment options during inpatient hospitalization. Future examinations of the rationale for combining antipsychotics, along with the long‐term safety, tolerability, and cost effectiveness of these therapies, in youth are urgently needed.

Published: July 2014

AbstractNew robust luminescent solar concentrators were produced by growing Eu(TTA)3phen‐containing parylene thin films on poly(methyl methacrylate) slabs through a novel co‐deposition process. As it is the first time that Eu(TTA)3phen molecules were inserted in parylene matrix, the deposition process was investigated, and the features of the samples were extensively analyzed. Fourier transform infrared spectroscopy analysis demonstrated the integrity of the vacuum‐sublimated Eu(TTA)3phen molecules. Atomic force microscope analysis showed the very flat surface of the films (Rq = 3.7 nm), which is strategic in luminescent solar concentrators (LSCs) for minimizing the light scattering at the air/film interface. The optical measurements demonstrated that Eu(TTA)3phen‐containing parylene exhibits higher absorption than the conventional Eu(TTA)3phen films and the luminescence peaks characteristic of Eu(TTA)3phen compound. This indicates that the Eu complex is not affected by the matrix interaction thus maintaining its extremely large Stokes shift. Moreover, the parylene matrix improves the luminescence intensity of the films: in fact, under the same absorption, these films show a luminescence intensity more than two times higher than standard Eu(TTA)3phen ones. The current–voltage (I–V) measurements show that, under the same quantity of Eu(TTA)3phen, Eu(TTA)3phen‐containing parylene LSCs produce a current density more than twice as high as LSC without parylene and that their efficiency decreases more than ten times slower than organic‐based LSCs at increasing illuminating area, thus highlighting the feasibility of developing large size LSCs.

Metal‐conducting polymer interface studied by Kelvin probe microscopy: Au and Al on poly(3‐octyl‐thiophene)
Authors: Abad Jose , Colchero Jaime 
Published: July 2014

ABSTRACTIn this work, we report a Kelvin probe microscopy investigation on the structural and electronic properties of gold and aluminum thin films evaporated on poly(3‐octyl‐thiophene) films. Our experimental setup allows us to perform scanning force microscopy (SFM) studies of the same area even if the sample is taken out of the SFM system for different processes (Au and Al evaporation). This allows a detailed study of the effect of adsorbed metal particles on the morphology and electrical properties of polymer thin films at the nanoscale. We found different behavior for both metals in morphology and electrical properties at the interface. These results can contribute to explain what happens at the metal–polymer interface of the devices when the metal contacts are grown. Thereby the observed nanoscale structural changes can be correlated with the overall performance of the fabricated devices. © 2014 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym.

SummaryBackgroundWhile the prevalence of childhood wheeze continues to increase in many countries, decreasing trends have also been reported. This may be explained by increased use of asthma medication, which effectively suppresses wheeze symptoms. In this study we investigated trends in wheeze in Dutch school children between 1989 and 2005, and their association with medication use.MethodsIn five repeated cross‐sectional surveys between 1989 and 2005, parents of all 5‐ to 6‐year‐old and 8‐ to 11‐year‐old children eligible for a routine physical examination were asked to complete a questionnaire on their child's respiratory health. We identified all children for whom a questionnaire was completed in two successive surveys. Children were grouped according to birth year and classified into one out of four wheeze categories: “no wheeze,” “discontinued wheeze,” “continued wheeze,” or “new‐onset wheeze.”ResultsIn total, 3,339 children, born in 1983 (N = 670), 1988 (N = 607), 1992 (N = 980), and 1995 (N = 1,082), participated twice. Over the study period, the proportion of children with “no wheeze” increased from 73.8% to 86.1% (Ptrend < 0.001), while the proportion of children with “discontinued” and “continued” wheeze decreased from 13.2% to 6.3% (Ptrend < 0.001) and from 8.8% to 3.1% (Ptrend < 0.001), respectively. Medication use was consistently associated only with the presence of wheeze symptoms and this association did not change over time (Pbirth year × medication use > 0.05 for all wheeze categories).ConclusionAn increasing trend of Dutch school children with “no wheeze,” and decreasing trends of children with “discontinued” and “continued” wheeze between 1989 and 2005 could not be explained by (increased) medication use. This suggests that wheeze prevalence is not masked by medication use, but is truly declining. Pediatr Pulmonol. 2015; 50:665–671. © 2014 Wiley Periodicals, Inc.

AbstractDer moderne Hoch‐ und Geschossbau benötigt ganzheitlich auf Nachhaltigkeit ausgerichtete Gebäudekonzepte, die ein hohes Maß an Nutzungsflexibilität und Multifunktionalität bieten und hierdurch die Bauwerkslebensdauer und ‐wirtschaftlichkeit erhöhen [1]. Hierbei weisen Deckenkonstruktionen ein besonderes Verbesserungspotential auf. Multifunktionale und integrierte Deckensysteme können einen entscheidenden Beitrag zur Schaffung nachhaltiger Gebäudestrukturen leisten.Im vorliegenden Artikel wird ein neuartiges, multifunktionales Deckensystem in Stahl‐Beton‐Verbundbauweise (InaDeck) vorgestellt, welches die vollständige Unterbringung aller gebäudetechnischen Bestandteile innerhalb eines Deckenzwischenraumes ermöglicht. Die Deckenelemente bestehen aus Verbundträgern mit Einzelflansch und vorgespanntem Betongurt sowie einer Verbunddübelleiste als Verbundmittel (filigrane Verbundträger). Zur flexiblen Leitungsführung sind große Stegöffnungen im Verbundträger angeordnet. Durch den vorgespannten Betongurt an der Querschnittsunterseite der Deckenelemente kombiniert das Deckensystem gute bauphysikalische Eigenschaften und Brandschutzmerkmale mit großen Spannweiten für eine hohe Flexibilität und eine variable Grundrissgestaltung. Der Artikel verdeutlicht die vielschichtigen Wechselwirkungen zwischen den Fachdisziplinen Gebäudetechnik, Bauphysik, Brandschutz sowie Tragwerksplanung.Multifunctional composite slab system with integrated building services – Studies on the load bearing and fire behavior, thermal efficiency and sustainability of a novel composite floor system. Modern multi‐story buildings require holistic and sustainable building conceptions that provide a high flexibility of use and multi‐functionality and thereby increase the building’s service life and economy [1]. Special potential for improvement in this case provides the research area of floor‐slab structures. Multifunctional and integrated floor‐slab‐systems can make a significant contribution to the creation of sustainable building structures.In this paper, a novel multi‐functional composite floor system (InaDeck) is presented which incorporates all building services and installations into the structural element by means of an integrated installation floor. The floor‐slab elements are made of prestressed composite beams with single flange and continuous shear connectors (filigree composite beams) which have large web openings for the routing of integrated building services. Due to a pre‐stressed concrete chord at the bottom side of the cross section, the slab system features improved physical and fire protection characteristics and provides wide spans for increased flexibility at the same time. The article highlights the complex interactions between the disciplines of building services, building physics, structural engineering and fire protection.
