Authors: Qin Zhongyue , Chen Yuyue , Zhang Peng , Zhang Guangyu , Liu Yan 
Published: March 2010

AbstractCu(II) complex bamboo pulp fabric (CBPF) was prepared by treating bamboo pulp fabric with the copper liquor. Washing fastness and the releases of Cu(II) were measured by the washing test. Antibacterial performance of CBPF against Escherichia coli and Staphylococcus aureus was evaluated. The morphology of Cu(II) on the fiber surface was characterized with scanning electron microscope. FTIR spectroscopy and X‐ray photoelectron spectrometry were used to detect the chemical bonding between Cu(II) and cellulose. X‐ray diffraction, thermogravimetry and mechanical test were used to investigate the effect of Cu(II) on the crystallinity, thermal stability, and mechanical property of bamboo fabric. The results showed that Cu(II) ion was bonded to fiber surface, especially via forming metal complex with hydroxyl of cellulose, and the resultant complex CBPF demonstrated excellent antibacterial activity and good thermal stability. In comparison with those of the bamboo pulp fabric in the condition that mechanical properties have no significant change, the crystallinity was decreased from 44.8% to 40.5% after treatment. © 2010 Wiley Periodicals, Inc.

Selective Hydrogenolysis of Glycerol to Propylene Glycol on Cu–ZnO Composite Catalysts: Structural Requirements and Reaction Mechanism
Authors: Wang Shuai , Zhang Yichi , Liu Haichao 
Published: March 2010

AbstractCu–ZnO catalysts were prepared by homogeneous coprecipitation with varying Cu/Zn atomic ratios (0.4–2:1). The catalysts were examined in selective hydrogenolysis of glycerol to propylene glycol. Although propylene glycol selectivities remained essentially constant (over 93 %) on the different Cu–ZnO catalysts, the turnover frequencies changed markedly with the Cu/Zn ratio, and reached the greatest value at the ratio of 1:1. Such activity dependence on the Cu/Zn ratio was in parallel with the change in the interaction between Cu and ZnO and in the Cu microstrain, as a consequence of the effects on the crystalline phases of hydroxycarbonate precursors for the Cu–ZnO catalysts, reflecting the structural requirements for glycerol hydrogenolysis. The hydrogenolysis mechanism was also examined and apparently involves kinetically relevant glycerol dehydrogenation to glyceraldehyde on Cu–ZnO and subsequent glyceraldehyde dehydration and hydrogenation to propylene glycol. The mechanism is consistent with the observed superior activities of the more strained Cu particles, and the higher propylene glycol selectivities obtained at higher glycerol and hydrogen concentrations. These findings provide a rationale for the design of more effective Cu‐based catalysts in selective hydrogenolysis of glycerol and other biomass‐derived polyols, for example, by synthesis of highly strained Cu particles strongly interacting with ZnO or other oxide supports.
Explicit nonlinear predictive control for a magnetic levitation system
Authors: Ulbig A. , Olaru S. , Dumur D. , Boucher P. 
Published: March 2010

AbstractThe paper presents a methodology for the construction of an explicit nonlinear control law via approximation of the nonlinear constrained finite‐time optimal control (CFTOC). This is achieved through an approximate mapping of a general nonlinear system in a set of linear piecewise affine (PWA) systems. The key advantages of this methodology are two‐fold. First, the construction of an analytic solution of the CFTOC problem leads to an efficient explicit implementation. Second, by taking advantage of model predictive control's systematic fashion to handle constraints, an improved performance can be obtained for the closed‐loop system. The proposed theory is applied in real‐time for a system with fast dynamics: a magnetic levitation benchmark. Copyright © 2010 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Sensitive and selective liquid chromatography–tandem mass spectrometry method for the determination of metoclopramide in human plasma: application to a bioequivalence study
Authors: Inamadugu Jaswanth Kumar , Damaramadugu Rajasekhar , Mullangi Ramesh , Ponneri Venkateswarlu 
Published: March 2010

AbstractA simple, sensitive and rapid method has been developed and validated for determination of the metoclopramide (MCP) in 100 μL human plasma. The analytical procedure involves a liquid–liquid extraction method using tramadol as an internal standard (IS). Chromatographic separation was carried out on a HyPURITY ADVANCE column using a mobile phase consisting of acetonitrile and 10 mm ammonium acetate buffer in the ratio of 80:20 (v/v) at a flow rate of 0.3 mL/min. The total run time of analysis was 2.5 min and elution of MCP and IS occurred at 0.9 and 1.3 min, respectively. A linear response function was established for the range of concentrations 0.53–42.07 ng/mL (r > 0.99). The intra‐ and inter‐day precision values for MCP met the acceptance as per FDA guidelines. MCP was stable in a battery of stability studies viz., bench‐top, auto‐sampler and freeze–thaw cycles. The developed assay method was successfully applied to an oral bioequivalence study in humans.

Authors: Lan Tian , Bi Huichang , Xu Suowen , Le Kang , Xie Zhiyong , Liu Yiwei , Huang Heqing 
Published: March 2010

AbstractSphingosine kinase (SphK) is a key enzyme in modulating the levels of sphingosine 1‐phosphate (S1P) as well as an important enzyme in numerous biological responses. Using C17‐sphingosine as a substrate, we established a rapid, sensitive and highly efficient method for determination of SphK activity by analyzing the product C17‐sphingosine 1‐phosphate (C17‐S1P) using liquid chromatography–tandem mass spectrometry. The standard curve for C17‐S1P was linear over a wide range (10–1000  ng/mL) with correlation coefficient (r2) greater than 0.999. The lower limit of quantification for C17‐S1P was 10  ng/mL. The Km values for C17‐sphingosine and ATP were determined to be 28.17 and 188.5  mM, respectively. More importantly, the SphK activity dramatically increased in cultured HEK 293 cells expressing wild‐type SphK1 as well as cells treated with tumor necrosis factor‐a, a sphingosine kinase activator. In contrast, the SphK activity decreased in cultured HEK 293 cells treated with dimethylsphngosine, a sphingosine kinase inhibitor. In conclusion, this method was sensitive and rapid in the determination of SphK acitivity, providing striking utilities in exploring the sphingosine kinase signaling pathway and screening active compounds targeting SphK activity.

Published: March 2010

AbstractA sensitive and selective liquid chromatography–tandem mass spectrometry method for the determination of piracetam in rat plasma was developed and validated over the concentration range of 0.1–20 µg/mL. After addition of oxiracetam as internal standard, a simplified protein precipitation with trichloroacetic acid (5%) was employed for the sample preparation. Chromatographic separation was performed by a Zorbax SB‐Aq column (150 × 2.1 mm, 3.5 µm). The mobile phase was acetonitrile–1% formic acid in water (10:90 v/v) delivered at a flow rate of 0.3 mL/min. The MS data acquisition was accomplished in multiple reaction monitoring mode with a positive electrospray ionization interface. The lower limit of quantification was 0.1 µg/mL. For inter‐day and intra‐day tests, the precision (RSD) for the entire validation was less than 9%, and the accuracy was within the 94.6–103.2% range. The developed method was successfully applied to pharmacokinetic studies of piracetam in rats following single oral administration dose of 50 mg/kg. Copyright © 2010 John Wiley & Sons, Ltd.
A sensemaking approach to trade‐offs and synergies between human and ecological elements of corporate sustainability
Authors: Angus‐Leppan Tamsin , Benn Suzanne , Young Louise 
Published: March 2010

AbstractThis paper considers the complex relationships between the human and ecological elements of sustainability that exist in the minds of stakeholders and argues that a sensemaking approach allows these to be better understood and compared. This is supported by the results of a study, set in a financial institution, exploring the relationships between these non‐financial elements of corporate sustainability. The viewpoints of middle management, branch and contact centre employees, executives, a community consultative council, suppliers and a community partner of a large Australian bank obtained in in‐depth interviews are analysed and compared utilizing an innovative methodology of semantic analysis. We find that these stakeholders' perceptions of the human–ecological relationship differ by group, containing different mixes of trade‐offs and synergies between the non‐financial elements of corporate sustainability.

Published: March 2010

AbstractStudy of risk factors for violence to prominent people is difficult because of low base rates. This study of harassers of the royal family examined factors suggested in the literature as proxies for violence—breaching security barriers, achieving proximity, approach with a weapon, and approach with homicidal ideation. A stratified sample of different types of approach behaviour was randomly extracted from 2,332 Royalty Protection Police files, which had been divided into behavioural types. The final sample size was 275. Significant differences in illness symptomatology and motivation were found for each proxy group. Querulants were significantly over‐represented in three of the four groups. There was generally little overlap between the proxy groups. There is no evidence of the proxy items examined being part of a “pathway to violence”. Different motivations may be associated with different patterns of risk. Risk assessment must incorporate knowledge of the interactions between motivation, mental state, and behaviour. Copyright © 2010 John Wiley & Sons, Ltd.

Published: March 2010

AbstractThis paper presents a new learning system for a hydroelectric unit of energy (HUE) by using desktop virtual reality (VR) techniques. The software offers the possibility to understand the relation between the physical structures of a UHE, through computer simulations, graphical outputs, and animations. Three learning courses are offered. Educative is the first course that allows familiarizes the student with the structure and with the constituent pieces of a HUE, as well its general and technical information. The second course, maintenance, uses the learning approach based on practice and offers different learning levels, divided into three modes: automatic, guided, and exploratory, in which these modes are accessed according to the acquired degree of knowledge by the user in relation to maintenance procedures. The last course, operation learning, allows the student to visualize the operation of HUE during a certain event as the electromechanical dynamics of the turbine‐generator assemblage in the virtual world by the visualization of several requisite conditions before the startup procedure of HUE. Finally, it was made a performance comparison between the Electrical Engineering students which used the learning module with the case where that was not adopted. © 2010 Wiley Periodicals, Inc.

Modeling an immersive VR driving learning platform in a web‐based collaborative design environment
Authors: Liang Janus S. 
Published: March 2010

AbstractA fully spatial immersive and interactive visualizations system that provides extremely vivid stereoscopic views of sceneries in 3D is developed based on the technologies of CAD, database, distributed virtual reality and computing networking. The platform, immersive VR automotive driving learning (imseADL), is developed in a web‐based collaborative design environment at the YTIT for teaching and research. The platform will can also be tools for complex system analysis and design, such as collision, stability for driving, safety, etc., in the future. In addition, the computer generated images (objects and scenes) can be tailored made to produce any simulated environment for training and skill evaluation purposes within a short period of time. In this paper, based on the analysis of the dynamic nature of collaborative design process, a new framework of collaborative design for modeling an imseADL is described. This framework adopts an agent‐based approach and relocates designers, system and the supporting agents in a unified knowledge representation scheme for imseADL design. A prototype system of the proposed framework is implemented and its feasibility is evaluated using a real design scenario whose objective is designing an imseADL. Meanwhile, the imseADL will also provide a means for learners to study their operations without the need to physically visiting these facilities. More importantly, experiments can be performed on the virtual scenes whereby operation and design parameters can be changed in a safe and controlled situation. © 2010 Wiley Periodicals, Inc.

Authors: Gao Zhenguo , Cai Shaobin , Zhao Yunlong , Liu Yanwen , Xu He 
Published: March 2010

AbstractCollaboration generally leads to better learning outcomes than individual work, and efficient communication is of essential importance to collaborative learning environments. Adobe's Flash Media Server (FMS) together with its Flash provides an efficient a platform for developing collaborative learning environments. Using FMS, we have designed and developed a collaborative learning environment targeted for students' self‐teaching of hydraulic experiments. The collaborative learning environment consists of multi‐user collaboration supporting courseware modules called as virtual hydraulic circuits/equipments. In this paper, the Modeler‐View‐Controller (MVC) architecture designed for the collaborative courseware modules was provided, and key steps of developing such modules using FMS were described. The effect of the courseware modules in helping students in making preparations for actual experiments was examined, and students' attitudes toward the modules were surveyed and analyzed. Results showed that collaborative courseware modules can lead to better learning outcome, and efficient communication especially audio communication is more preferred by the tested students. © 2010 Wiley Periodicals, Inc.

On emotions and salsa: some thoughts on dancing to rethink consumers
Authors: Hewer Paul , Hamilton Kathy 
Published: March 2010

Abstract

Dance forms are a big business, highly marketable commoditized cultural universes, with a plethora of markets constructed around their spirit, vitality and possibilities. In this paper, we explore one particular dance form, that of Salsa, arguing that as consumer researchers we look for a more vibrant vocabulary and mindset with which to capture the experiential and transcendental nature of such social associations. We demonstrate that the metaphor of dancing is useful to revitalize our notions of consumer actions; taking them out of the grey mundane of calculative and rational action into the possibilities of emotional economies constructed around the effervescence and vitality of the social (cf. Maffesoli, 1996).

Consumers' transformations in a liquid society: introducing the concepts ofautobiographical‐concernanddesire‐assemblage
Authors: Gaviria Pilar Rojas , Bluemelhuber Christian 
Published: March 2010

AbstractIn our fast‐paced world, consumers are increasingly exposed to transformation, for instance, in the form of divorce or emigration. These transformations are associated with a willingness to embrace changes in personal consumption. From a temporal perspective, contemporary consumer research on transformations has favoured one point of view – past or future – such as the research done on possible future selves or on feelings of nostalgia.However, a more integrated perspective, in which both past and future become dynamically involved in ensuring individual life continuity, still seems to be lacking. It is our belief that the philosophical concepts ofexistential hermeneuticsandnarrative identitycan stimulate researchers into closing this research gap.According toexistential hermeneutics, human beings are essentially self‐interpreters. They deal with the nature of their own existence by disclosing their personal possibilities and updating former experiences in new life contexts. This self‐interpreter condition is articulated in the multiple self‐narratives that an individual can construct. The narrative acts as a form of support in the process of constructing a personal identity, by offering stability and continuity to the fragmented life experiences of a rapidly mutating world.Based on these philosophical concepts, the specific goal of this paper is to propose two major implications for research on consumer life transformations: theautobiographical‐concern– the existential pre‐occupation of making a personal life‐narrative coherent by interpreting simultaneously one's own personal past and future – and the understanding of desire as being a constructivist exercise –desire‐assemblage– that may accompany this phenomenon.Copyright © 2010 John Wiley & Sons, Ltd.
Showing doing. The art–science debate in a performative perspective
Authors: Bode Matthias 
Published: March 2010

Abstract

The relationship between art and science plays an important role in the evolution of Interpretive Consumer Research (ICR). The discussion is currently stuck between a conception of art as mimesis (imitating reality), and as poiesis (imaginative creation of reality). The consequence is an inability to move beyond the frame of art or science and release the potentials of both sides. This paper introduces a performative perspective on art in a research context. Instead of separating art and science, a performative perspective tends to integrate both aspects in a processual and behavioural way. A central aspect is the concept of performance as restored behaviour that is characterized by a tension between the mimetic and the ‘real’. Hereby, the act of ‘doing something’ transforms into ‘showing doing’. Social and aesthetic behaviour becomes intertwined and advances a traditional, object‐oriented concept of art. In a performativity context, doing research also becomes another form of ‘showing doing’ with an enactement impact. Such a perspective goes beyond a view which sees art only as a data source or an additional element of presenting research results. Art as a performance disrupts the linear notion of the research process, so that artistic modes and performances are at the intersection of method, research, object of research and representation of research.

Published: March 2010

AbstractAufgrund des wachsenden Bedarfs an Metalloxid‐Nanopartikeln für verschiedenste Anwendungen mit steigenden Anforderungen ist ihre gezielte Herstellung in definierten Größen und Formen sowie ihre Stabilisierung gegen Agglomeration von großer Bedeutung. Insbesondere Nanopartikel ternärer oder dotierter Metalloxide, die als funktionale Materialien benötigt werden, sind heute kaum in größeren Mengen zugänglich. Es wird die nicht‐wässrige Sol‐Gel‐Synthese von Nanopartikeln vorgestellt, die eine Herstellung hochkristalliner Nanopartikel für verschiedenste Metalloxide bereits bei relativ niedrigen Reaktionstemperaturen erlaubt und ihre effektive Stabilisierung zur Herstellung stabiler Dispersionen zulässt.
