Using the theory of planned behavior to understand health professionals' attitudes and intentions to refer cancer patients for psychosocial support
Authors: Kam Ling Yu Keith , Knott Vikki E. , Wilson Carlene , Chambers Suzanne K. 
Published: December 2010

AbstractObjective: To describe oncology professionals' patterns of referral to existing community and psychosocial support services, including complementary therapies utilizing the theory of planned behavior (TPB).Methods: An exploratory cross‐sectional survey of 72 oncology professionals including nurses (73.6%), medical practitioners (19.4%) and allied health professionals (6.9%) from health institutions in South Australia assessed past referral patterns, perceived attitudes of peers, control over and attitudes toward, referral, past referral practices and how these impact on intention to refer.Results: Referral to support services such as a cancer helpline, allied health or complementary services was infrequent. A hierarchical regression entering awareness, past referral and the TPB variables (attitude, subjective norm and perceived control) explained 51% of the variance on the outcome ‘intention to refer’. Barriers to referral for support included lack of local services for remote patients, and financial considerations.Conclusion: Interventions with health professionals should focus on the development of a culture, which recognizes the importance of addressing a breadth of patient needs across the cancer trajectory. Education and support for health professionals is required to ensure that they feel comfortable discussing support needs and referring to appropriate support services.

Impact on the replacement of Phe by Trp in a short fragment of Aβ amyloid peptide on the formation of fibrils
Authors: Chaudhary Nitin , Nagaraj Ramakrishnan 
Published: December 2010

AbstractAβ16–22 (Ac‐KLVFFAE‐NH2) is one of the shortest amyloid fibril‐forming sequences identified in β‐amyloid peptide. At neutral pH, the peptide forms fibrils in the concentration range of 0.2–2.0 mM after ≥ 10 days of incubation. Structures of the fibrils proposed based on solid‐state NMR and MD simulations studies suggest antiparallel arrangement of β‐strands and aromatic interactions between the Phe residues. In an effort to examine the role of aromatic interactions between two Phe residues in Aβ16–22, we have studied the self‐assembly of Aβ16–22 (AβFF) and two of its variants, Ac‐KLVFWAE‐NH2 (AβFW) and Ac‐KLVWFAE‐NH2 (AβWF). The peptides were dissolved in methanol (MeOH) at a concentration of 1 mM and in water (AβFW and AβWF, 1 mM; AβFF, 330 µM). Peptide solutions (100 µM) were prepared in 50 mM sodium phosphate buffer at pH 7 by diluting from MeOH and water stock solutions. AβFW forms amyloid‐like fibrils immediately from MeOH, as indicated by atomic force microscopy. Dilution of AβFW into phosphate buffer from stock solution prepared in MeOH results in fibrils, but with different morphology and dimensions. The secondary structure potentiated by MeOH seems to be important for the self‐assembly of AβFW, as fibrils are not formed from water where the peptide is unordered. On the other hand, AβFF and AβWF do not form amyloid fibrils rapidly from any of the solvents used for dissolution. However, drying of AβWF from MeOH on mica surface gives rod‐like and fibrous structures. Our study indicates that positioning of the aromatic residues F and W has an important role to play in promoting self‐assembly of the Aβ16–22 peptides.

Development of a high transconductance GaN MMIC technology for millimeter wave applications
Authors: Haupt C. , Maroldt S. , Quay R. , Pletschen W. , Leuther A. , Ambacher O. 
Published: December 2010

AbstractIn this paper we report on the development of high transconductance GaN‐based high electron mobility transistors (HEMTs) to improve the performance at W‐Band frequencies. At first, the influence of the barrier thickness on the maximum transconductance (gm,max) was investigated by using two different technologies: growth of thin barrier layers and deep gate recess. Second, the effect of a gate length reduction down to 100 nm on gm,max was examined. The reduction of the barrier thickness results in a strong increase of the extrinsic transconductance up to 600 mS/mm. The technology was then used to fabricate HEMTs, with a cut‐off frequency of 110 GHz, which are compatible to a MMIC technology (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Published: December 2010

AbstractWhispering‐gallery‐mode (WGM) GaInP micro‐disc (MD) and micro‐ring (MR) resonators (diameters D=1‐3 mm, quality factors Q up to 5×103) with embedded InP quantum dots (size/density ∼100 nm/∼109cm‐2, emission range 720‐770 nm) have been fabricated using a wet oxidation technique. Ultralow (sub‐nanoWatt) lasing thresholds for a single InP quantum dot have been demonstrated for these resonators at 15 K under optical pumping. Observed thresholds are two orders of magnitude lower than for single InAs QD lasing (M. Nomura et al., Opt. Express 17, 15975 (2009) [1]). (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractThe mechanisms determining emission of holes in self‐assembled Ge quantum dots (QDs) embedded in the p‐type Si matrix have been investigated. Specimens were prepared by molecular beam epitaxy (MBE). Electrical methods such as deep level transient spectroscopy (DLTS) and capacitance versus voltage (C‐V) measurements were used for the study. The emission mechanisms were identified by measuring a QD‐related signal as a function of the repetition frequency of the filling pulses with the reverse voltage and the pulse voltage as a parameter. An observed shift of the signal position or its absence versus the voltage parameters was interpreted in terms of thermal, tunnelling and mixed processes and attributed to the presence of a Coulomb barrier formed as a result of the charging effect. Thermal emission properties of the QDs were characterized under such measurement conditions that tunnelling contributions to the DLTS spectra could be neglected (© 2011 WILEY‐VCH Verlag GmbH & Co.

High breakdown voltage AlGaN/GaN HEMT by employing selective fluoride plasma treatment
Authors: Kim Young‐Shil , Lim Ji‐Yong , Kim Min‐Ki , Han Min‐Koo 
Published: December 2010

AbstractFluoride‐based plasma treatment was employed to improve reverse characteristics. The fluoride‐based plasma treatment using CF4 gas was performed on drain‐side gate edge region, where field plate metal is deposited, at an RF power of 30W for 120 sec. Experimental results showed that fluoride based plasma treated AlGaN/GaN HEMT had stable reverse blocking capability by successfully suppressing leakage current as well as increasing off‐state breakdown voltage (VBR) with minimized degradation in forward characteristics. Leakage current of untreated sample was increased in proportional to reverse bias voltage while that of fluoride plasma treated sample was remained at nano level. Fluoride plasma treatment improved breakdown voltage of device from 900 V to 1400 V with 16% decrease in output current (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Influence of database mistakes on journal citation analysis: remarks on the paper by Franceschini and Maisano, QREI (2010)

Published: December 2010

AbstractThis short note contains some remarks on a recent bibliometric survey about some of the major scientific journals in the field of Quality Engineering/Management (Qual. Reliab. Engng. Int. 2010; 26(6):593–604). In particular, thanks to Professor Woodall's precious indication, it has been freshly noticed that some results in the original work are biased by mistakes in the bibliometric databases (in this case Google Scholar). After a careful examination and correction of biased data, a synthetic analysis of the typical mistakes of bibliometric databases is presented, focussing the attention on the importance of using robust bibliometric indicators.

Robust multiple model adaptive control: Modified using ν‐gap metric
Authors: Mahdianfar Hessam , Ozgoli Sadjaad , Momeni Hamid Reza 
Published: December 2010

AbstractA new robust adaptive control method is proposed, which removes the deficiencies of the classic robust multiple model adaptive control (RMMAC) using benefits of the ν‐gap metric. First, the classic RMMAC design procedure cannot be used for systematic design for unstable plants because it uses the Baram Proximity Measure, which cannot be calculated for open‐loop unstable plants. Next, the %FNARC method which is used as a systematic approach for subdividing the uncertainty set makes the RMMAC structure being always companion with the µ‐synthesis design method. Then in case of two or more uncertain parameters, the model set definition in the classic RMMAC is based on cumbersome ad hoc methods. Several methods based on ν‐gap metric for working out the mentioned problems are presented in this paper. To demonstrate the benefits of the proposed RMMAC method, two benchmark problems subject to unmodeled dynamics, stochastic disturbance input and sensor noise are considered as case studies. The first case‐study is a non‐minimum‐phase (NMP) system, which has an uncertain NMP zero; the second case‐study is a mass‐spring‐dashpot system that has three uncertain real parameters. In the first case‐study, five robust controller design methods (H2, H∞, QFT, H∞ loop‐shaping and µ‐synthesis) are implemented and it is shown via extensive simulations that RMMAC/ν/QFT method improves disturbance‐rejection, when compared with the classic RMMAC. In the second case‐study, two robust controller design methods (QFT and mixed µ‐synthesis) are applied and it is shown that the RMMAC/ν/QFT method improves disturbance‐rejection, when compared with RMMAC/ν/mixed−µ.

The effects of a mindfulness‐based stress reduction programme on pre‐sleep cognitive arousal and insomnia symptoms: a pilot study
Authors: Cincotta Andrea L. , Gehrman Philip , Gooneratne Nalaka S. , Baime Michael J. 
Published: December 2010

AbstractThe use of mindfulness meditation for stress management has grown in recent years. Practising mindfulness meditation has been shown to help manage stress and decrease arousal, both of which are associated with difficulty sleeping; thus, mindfulness‐based stress management programmes may have a positive impact on sleep. The effects of an 8‐week mindfulness‐based stress management programme on pre‐sleep cognitive arousal and insomnia symptoms were examined. Sleep was assessed with self‐report measures and objectively with actigraphy. Results showed lower levels of pre‐sleep arousal and milder subjective insomnia symptoms post‐intervention. Longer duration of meditation practice in the final week was associated with greater decreases in cognitive arousal scores. No improvements were found in objectively measured sleep variables. The results of this study suggest that mindfulness‐based stress management can lead to improvements in cognitive arousal and self‐reports of sleep, even in the absence of objective evidence of sleep improvement.

The role of perceived control in the relationship between job insecurity and psychosocial outcomes: moderator or mediator?
Authors: Elst Tinne Vander , De Cuyper Nele , De Witte Hans 
Published: December 2010

AbstractThe aim of the current study was to address the intervening role of perceived control in the job insecurity–strain relationship. Two alternatives were investigated: (1) perceived control as a buffer of the relationship between job insecurity and outcome variables (i.e. job satisfaction, organizational commitment, psychological distress and turnover intentions); and (2) perceived control as a mediator of the relationship between job insecurity and the outcomes. Cross‐sectional data of 211 employees were used to test the hypotheses. The results showed that perceived control did not buffer the relationship between job insecurity, and job satisfaction, organizational commitment, psychological distress and turnover intentions. However, perceived control was found to partially mediate the association between job insecurity and these outcomes. The results are explained using the cognitive theory of stress and coping of Lazarus and Folkman, and suggest that job insecurity is stressful because it decreases the experience of control.

Longitudinal relations between psychosocial work environment, stress and the development of musculoskeletal pain
Authors: Larsman Pernilla , Lindegård Agneta , Ahlborg Gunnar 
Published: December 2010

AbstractExposure to psychosocial stressors at work is hypothesized to be related to the development of musculoskeletal pain through the mechanism of work‐related stress. This hypothesis has received support in cross‐sectional studies. Few longitudinal studies that specifically address this hypothesized mediating mechanism are however reported in the literature. The aim of the present study was to test this hypothesis in a longitudinal process model. A 3‐wave mixed occupations cohort‐study was performed with a baseline questionnaire survey in 2004; and with 2‐year follow‐ups in 2006 and 2008. A latent variable process model was tested using structural equation modeling. Since focus of the study was on the process of pain development, only those participants considered pain free at baseline were included (n = 1 133). The results indicate that exposure to high work demands may cause long‐term work‐related stress. The hypotheses that work demands and control influence the development of pain, and that this relation is mediated by work‐related stress were not supported. No indications of reversed causality were found. In order to further elucidate the hypothesized stress mechanism, future research needs to focus on the development of site‐specific musculoskeletal pain in longitudinal studies including repeated measures with shorter lags between measurement waves.

Published: December 2010

AbstractA detailed study is presented on the formation of MoO2 nanoparticles from the dissolution of the precursor to the final rodlike product, with a focus on the exploration of the inorganic reaction occurring ahead of the nucleation step, and interplay between size and crystal structure of MoO2. In situ X‐ray absorption spectroscopy experiments show that the crystallization and the growth process of MoO2 nanorods is initiated by rapid reduction of the MoO2Cl2 precursor in benzyl alcohol and acetophenone. This reaction triggers the nucleation of 2 nm MoO2 particles with spherical shape and hexagonal crystal structure. The transformation from spheres into rods emerges as a complex process driven by oriented attachment. High‐resolution transmission electron microscopy and X‐ray diffraction results provide evidence that the 2 nm particles first aggregate into 5–20 nm‐large oriented assemblies. The increase in particle size induces the phase transition from hexagonal to the less symmetrical monoclinic crystal structure, and finally the transformation into rods. Is it shown that electrodes for lithium‐ion batteries based on MoO2 nanorods have a long‐term cycling life. The specific discharge capacity even after 200 cycles at a discharge rate of 1 C is about 300 Ah kg−1.
Generalized continua and non‐homogeneous boundary conditions in homogenisation methods
Authors: Forest S. , Trinh D.K. 
Published: December 2010

AbstractExtensions of classical homogenization methods are presented that are used to replace a composite material by an effective generalized continuum model. Homogeneous equivalent second gradient and micromorphic models are considered, establishing links between the macroscopic generalized stress and strain measures and the fields of displacement, strain and stress inside a volume element of composite material. Recently proposed non‐homogeneous boundary conditions to be applied to the unit cell, are critically reviewed. In particular, it is shown that such polynomial expansions of the local displacement field must be complemented by a generally non‐periodic fluctuation field. A computational strategy is introduced to unambiguously determine this fluctuation. The approach is well‐suited for elastic as well as elastoplastic composites.
The undulatory motion of a chain of particles in a resistive medium
Authors: Bolotnik N. , Pivovarov M. , Zeidis I. , Zimmermann K. 
Published: December 2010

AbstractThe motion of a finite chain of identical bodies along a straight line in a resistive medium is studied. The major aim of this study is to investigate the fundamental properties of such systems, in particular, their ability to move from a state of rest and sustain the motion at constant average velocity in media with different resistance properties and the influence of the control strategy on the motion. The motion is excited and controlled by changing the distances between the bodies of the chain. For a given friction law, the necessary and sufficient conditions for the system to be able to move from rest are established.
Genomisches Imprinting und Imprintingfehler
Authors: Horsthemke B. 
Published: December 2010

ZusammenfassungGenomisches Imprinting ist ein epigenetischer Prozess, bei dem die männliche und die weibliche Keimbahn bestimmte Genregionen durch Histonmodifikationen und DNA-Methylierung so prägen, dass nur das väterliche oder nur das mütterliche Allel eines Gens aktiv ist. Genomische Imprints werden in primordialen Keimzellen gelöscht, während späterer Phasen der Keimzellentwicklung neu etabliert und bei den somatischen Zellteilungen während der postzygotischen Entwicklung stabil weitergegeben. Fehler in der Entfernung der Imprints, ihrer Etablierung oder ihrer Erhaltung führen zu falschen epigenetischen Mustern und Expressionsprofilen, die spezifische Erkrankungen verursachen können. Imprintingfehler können spontan, ohne jegliche Änderungen in der DNA-Sequenz, auftreten (primäre Imprintingfehler) oder als Folge einer Mutation in einemcis-regulatorischen Element oder einemtrans-aktiven Faktor (sekundäre Imprintingfehler). Die Unterscheidung zwischen primären und sekundären Imprintingfehlern ist für die Abschätzung des Wiederholungsrisikos in betroffenen Familien wesentlich.

A graph clustering algorithm based on a clustering coefficient for weighted graphs

Published: December 2010

Abstract
Graph clustering is an important issue for several applications associated with data analysis in graphs. However, the discovery of groups of highly connected nodes that can represent clusters is not an easy task. Many assumptions like the number of clusters and if the clusters are or not balanced, may need to be made before the application of a clustering algorithm. Moreover, without previous information regarding data label, there is no guarantee that the partition found by a clustering algorithm automatically extracts the relevant information present in the data. This paper proposes a new graph clustering algorithm that automatically defines the number of clusters based on a clustering tendency connectivity-based validation measure, also proposed in the paper. According to the computational results, the new algorithm is able to efficiently find graph clustering partitions for complete graphs.
Pneumatosis intestinalis versus pseudo-pneumatosis: review of CT findings and differentiation

Published: December 2010

Abstract
Pneumatosis intestinalis is defined as the presence of gas within the wall of the gastrointestinal tract. Originally described on plain abdominal radiographs, it is an imaging sign rather than a specific diagnosis and it is associated with both benign and life-threatening clinical conditions. The most common life-threatening cause of pneumatosis intestinalis is bowel ischaemia. Computed tomography (CT) is usually requested to detect underlying disease. The presence of pneumatosis intestinalis often leads physicians to make a diagnosis of serious disease. However, an erroneous diagnosis of pneumatosis intestinalis may be made (i.e. pseudo-pneumatosis) when intraluminal beads of gas are trapped within or between faeces and adjacent mucosal folds. The purpose of this pictorial essay is to review and describe the CT imaging findings of pneumatosis and pseudo-pneumatosis intestinalis and to discuss key discriminatory imaging features.
