The structural response of BCC Fe lattice loaded in [110] direction
Authors: Wang Jing‐Zhou , Zhang Jian‐Min , Xu Ke‐Wei 
Published: October 2008

AbstractThe structural response of BCC Fe lattice loaded in [110] direction has been investigated with MAEAM. The results show that, even if an orthorhombic path (b2≠b3) is applied, the deformation is spontaneous along the tetragonal path (b2≡b3) while b1 is less than 0.3449nm in compressive region. In addition to the initial BCC phase, a BCT phase and the other BCC phase appear also at stress‐free states. The BCT phase with the local maximum internal energy of ‐4.227eV is unstable and would slip spontaneously into the appeared BCC phase with the same minimum internal energy of ‐4.280eV as the initial BCC phase. The stable region ranges from ‐43.87eV/nm3 to 44.06eV/nm3 in the theoretical strength or from ‐7.34% to 6.49% in the strain correspondingly. Furthermore, the relations B11=B22, B13=B23 and B44=B55 occur at the initial state. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Complex zigzag flexoelectric walls in the Schlieren textures of MBBA: possibility for determination of two basic Schlieren textures with singular or non‐singular surface points
Authors: Hinov H. P. 
Published: October 2008

AbstractThe flexo‐dielectric behaviour of a homeotropic MBBA nematic layer has been experimentally studied. Asymmetric strong‐weak anchoring of the homeotropic nematic layer was achieved by treating the glass plates – one of them with lecithin ensuring the strong anchoring and the other with usual soap ensuring the weak anchoring. The application of a dc voltage with a sufficient amplitude led to the appearance of a complex texture consisting of gradient flexo‐dielectric deformations including Schlieren texture with many singular points and zigzag flexoelectric walls. The application of additional orienting a.c. voltage brought clarification of the Schlieren texture resembling that of the smectic‐C liquid crystal. Inversely, the application of an ac voltage across the homeotropic nematic layer led to formation of a nice Schlieren texture. The additional application of a d.c. voltage created complex zigzag gradient flexoelectric walls which connected the singular points in the Schlieren texture. In this way, one can determine for the first time how many points in the initial Schlieren texture are singular and how many points are non‐singular. (© 2009 WILEY‐VCH Verlag GmbH & Co.

Characterization of dislocation structures in copper single crystals using electron channelling contrast technique in SEM
Authors: Li Xiao‐Wu , Zhou Yang , Guo Wei‐Wei , Zhang Guang‐Ping 
Published: October 2008

AbstractThe dislocation structures induced by low‐plastic‐strain‐amplitude cyclic deformation of [111] multiple‐slip‐oriented Cu single crystals were investigated using electron channelling contrast (ECC) technique in scanning electron microscopy (SEM). At a low plastic strain amplitude γpl of 8.8 × 10–5, the saturated dislocation structure is mainly composed of labyrinth‐like vein structure (or irregular labyrinths), and the cyclic hardening behavior at such a low γpl is interpreted as being the result of dislocation multiplication by a Frank‐Read mechanism. As γpl increases to 4.0 × 10–4, the unsaturated dislocation structure exhibits two kinds of distinctive configurations, i.e., dislocation walls and misoriented cells. Interestingly, these misoriented dislocation cells are strictly aligned along the primary slip plane (111), constituting a unique persistent slip band (PSB) structure. Here, these cells are thus called PSB cells. In addition, there is a locally distinctive region comprising some cells having a recrystallization‐like feature in the whole structure of PSB cells. The formation of the structure of PSB cells is discussed. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
The influence of Pb‐ion irradiation on melt‐textured YBa2Cu3Ox crystals
Authors: Obaidat I. M. , Albiss B. A. , Claus H. , Gharaibeh M. , Hasan M. K. 
Published: October 2008

AbstractMelt‐textured YBa2Cu3Ox crystals have been irradiated along the c‐axis with 208Pb56+ ions corresponding to dose matching fields, BΦ = 0.5 T and BΦ = 2.0 T. Magnetization measurements were conducted along the ab plane of the samples. The strength of pinning sites was investigated by measuring magnetization hysterisis and the saturation remanent magnetization MR at several temperatures. We have found that the pinning strength was considerably enhanced after irradiation at both doses. Interestingly, the pinning strength at a Pb‐ion irradiation which corresponds to the dose matching field BΦ = 0.5 T, was found to be significantly larger than that at the dose matching field BΦ = 2.0 T at all temperatures.

Temperature‐tuned band gap energy and oscillator parameters of Tl2InGaSe4 semiconducting layered single crystals
Authors: Gasanly N. M. 
Published: October 2008

AbstractThe optical properties of Tl2InGaSe4 layered single crystals have been studied through the transmission and reflection measurements in the wavelength range of 500‐1100 nm. The analysis of room temperature absorption data revealed the presence of both optical indirect and direct transitions with band gap energies of 1.86 and 2.05 eV, respectively. Transmission measurements carried out in the temperature range of 10‐300 K revealed that the rate of change of the indirect band gap with temperature is γ = – 4.4 × 10‐4 eV/K. The absolute zero value of the band gap energy was obtained as Egi(0) = 1.95 eV. The dispersion of the refractive index is discussed in terms of the single oscillator model. The refractive index dispersion parameters: oscillator wavelength and strength were found to be 2.53 × 10–7 m and 9.64 × 1013 m–2, respectively. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractDysprosium (Dy) doped La3Ga5.5Nb0.5O14 single crystals were grown by the traditional Czochralski method along z‐axis. The structure of the crystal has been studied by X‐ray powder diffraction method, and the unit‐cell parameters are calculated to be a=8.22070 Å, c=5.12533 Å and V=299.965 Å3. The segregation coefficient of Dy3+ in La3Ga5.5Nb0.5O14 crystal was measured by X‐ray fluorescence analysis. For 1 mol% doping level in the melt, the distribution coefficient of Dy3+ was determined to be 0.341 wt%. Specific heat, thermal expansion and transmission spectrum of Dy: La3Ga5.5Nb0.5O14 single crystals have been measured. The fluorescence spectra of Dy3+: La3Ga5.5Nb0.5O14 crystals were measured at room temperature, and there were four emission transitions occurring at 479, 576, 662 and 754 nm, respectively. The fluorescent lifetimes measurement results show 1.0% Dy: La3Ga5.5Nb0.5O14 possesses shorter fluorescence decay time (303.4 μs) than does 1.0%Dy:LGS (436.12 μs). (© 2009 WILEY‐VCH Verlag GmbH & Co.

Comments and reconciliation of the Ni–Bi‐system thermodynamic reassessments
Authors: Vassilev G. , Gandova V. , Docheva P. 
Published: October 2008

AbstractThe binary Ni‐Bi alloys as well as multicomponent materials comprising systems like Ni‐Bi‐Sn, Ni‐Bi‐Sb etc. are recently considered as prospective for design of lead‐free solders. For that reason various authors focused their attention to the Ni‐Bi system thermodynamics. The studies identified five phases in the above system. Two of them (i.e., (Ni) and liquid), were treated as disordered substitutional solutions. The phase NiBi3 is stoichiometric and a standard two‐sublattice model was repeatedly applied to describe its Gibbs free energy, while for the nonstoichiometric NiBi phase, a three‐sublattice model was retained. The pure bismuth phase ((Bi)) is stoichiometric as well. The results are discussed and compared to literature thermochemical and topological data. In liquid state, strong repulsions between nickel and bismuth atoms are anticipated in the nickel rich‐side, but no data about a liquid phase miscibility gap is available yet. Therefore, the stability of the liquid phase has to be reassured, in spite of positive deviations from ideal behaviour. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
A new photoluminescent supramolecular inorganic‐organic hybrid zincophosphate complex pillared by carboxylate ligand through hydrogen bonding interactions

Published: October 2008

AbstractA new inorganic‐organic hybrid zincophosphate, [Zn(H2O)2(H2PO4)2]·2PABA (1) (PABA = p‐aminobenzoic acid), pillared by PABA ligands through hydrogen bonding interactions, has been synthesized and characterized. Single‐crystal X‐ray diffraction reveals that 1 crystallizes in the monoclinic P 21/c space group. The geometric feature in 1 is the 3D supramolecular structure constructed from alternately arranged organic and inorganic layers that consist of infinite parallel inorganic chains. These chains are extended to a 2D inorganic layer through intermolecule hydrogen bonding interactions between N atoms (from PABA ligand) and two O atoms (from adjacent inorganic chains). 1 was characterized by IR spectroscopy, XRD, DSC/TGA. The fluorescent property for 1 in solid state was also investigated at room temperature. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Authors: Saberi A. , Goharrizi A. Soltani , Ghader S. 
Published: October 2008

AbstractSodium bicarbonate is a substance which is produced in the middle stages of the soda ash production process. In this precipitation process, carbon dioxide gas is continuously injected into the bubble column reactor which contains carbonate and bicarbonate solutions. To elucidate the key parameters affecting precipitation kinetics, an experimental study was conducted to understand nucleation and growth in conditions of industrial reactor. The composition of the solution is followed during the crystallization process by titration. Magma density is also monitored and crystal size distribution (CSD) is obtained by sieving. The method of moments was used to determine nucleation and growth rates of crystals. The nucleation and growth rate correlations for sodium bicarbonate precipitation in industrial scale were correlated by empirical power laws as B = 26.685MT0.42Δw1.31 and G = 1.381×10–4Δw1.53. The nucleation and growth rate correlations obtained in this study can be used to simulate the crystallization of sodium bicarbonate plants. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
A strategy to communicate corporate social responsibility: cause related marketing and its dark side
Authors: Baghi Ilaria , Rubaltelli Enrico , Tedeschi Marcello 
Published: October 2008

AbstractCause related marketing (CRM) is a strategy that aims to communicate a company's striving for corporate social responsibility and to improve brand image. A strategy to increase consumers' emotional involvement toward a product–cause association is to describe the cause in vivid terms. In two experiments we investigated how vivid messages might increase the effectiveness of CRM strategy. We sought to demonstrate that a vivid description of the cause could influence consumers' preferences and trust in the effective use of money collected by selling the product. Experiment 1 results showed that individuals prefer products associated with a vivid message of the social cause rather than products associated with a pallid message. Experiment 2 results suggested that vivid messages induce more positive affective reactions and a higher trust in the effective use of money than pallid ones. In the final section, the implications of CRM for corporate social responsibility are discussed. Copyright © 2008 John Wiley & Sons, Ltd and ERP Environment.
Corporate environmental disclosures about the effects of climate change
Authors: Stanny Elizabeth , Ely Kirsten 
Published: October 2008

AbstractWe examine factors associated with the US S&P 500 firms' decisions to disclose information about the current and projected effects of climate change to institutional investors. Through the Carbon Disclosure Project, 315 institutional investors representing 41 trillion USD in assets asked the largest public firms to respond to a questionnaire about climate change. We explore whether firms' disclosures directed specifically to institutional investors are related to factors that have been found to explain voluntary disclosures to investors in general. In particular, we consider factors related to the level of scrutiny, since extant literature predicts that the cost of not disclosing increases with level of scrutiny. We find that size, previous disclosures and foreign sales are related to whether firms disclose information about climate change requested by institutional investors through the Carbon Disclosure Project.

Environmental supply chain management, ISO 14001 and RoHS. How are small companies in the electronics sector managing?
Authors: Nawrocka Dagmara 
Published: October 2008

AbstractThis study explores the use of environmental management systems for initiating and controlling environmental improvements in the context of supply chain cooperation. It examines how environmental requirements are reaching smaller companies in the electronics supply chain, especially in the light of recent legal changes such as enforcement of the RoHS Directive. It is based on qualitative interviews with environmental and purchasing managers of 21 small and medium‐sized companies. The results point out a lack of significant drivers for these companies to implement proactive measures when dealing with environmental issues, owing to limited customer pressure. RoHS and legal compliance are the only environmental customer criteria to be met, while ISO 14001 works as an optional supplier selection criterion. In consequence, companies are not focusing on environmental work within their supply chains, and the potential of influencing the environmental profile of suppliers by shaping their ISO 14001 is not used.

Exploring the moderating effect of financial performance on the relationship between corporate environmental responsibility and institutional investors: some Egyptian evidence
Authors: Wahba Hayam 
Published: October 2008

AbstractMuch of the existing literature has argued that those firms that invest in environmental initiatives attract more institutional investors. A noticeable problem with these studies is the assumption that the relationship between institutional investors and corporate environmental responsibility is a monotonic relationship that does not vary with firm financial performance. Initial findings of this study demonstrated that corporate environmental responsibility exerted a positive and significant coefficient on institutional ownership. However, when an interaction term between environmental responsibility and financial performance was included, the results verified that corporate environmental responsibility has a neutral impact on the preferences of institutional investors. Moreover, by classifying firms into two sub‐groups, according to their financial performance, environmental responsibility was found to have a positive and significant impact on institutional ownership only when financial performance is high.

Published: October 2008

AbstractObjectiveThe aim of this study was to compare two maintenance treatment conditions for weight‐restored anorexia nervosa (AN): individual cognitive behavior therapy (CBT) and maintenance treatment as usual (MTAU).MethodThis study was a nonrandomized clinical trial. The participants were 88 patients with AN who had achieved a minimum body mass index (BMI) of 19.5 and control of binge eating and purging symptoms after completing a specialized hospital‐based program. Forty‐six patients received 1 year of manualized individual CBT and 42 were in an assessment‐only control condition (i.e., MTAU) for 1 year. This condition was intended to mirror follow‐up care as usual. Participants in both the conditions were assessed at 3‐month intervals during the 1‐year study. The main outcome variable was time to relapse.ResultsWhen relapse was defined as a BMI ≤ 17.5 for 3 months or the resumption of regular binge eating and/or purging behavior for 3 months, time to relapse was significantly longer in the CBT condition when compared with MTAU. At 1 year, 65% of the CBT group and 34% of the MTAU group had not relapsed.DiscussionThe current findings provide preliminary evidence that CBT may be helpful in improving outcome and preventing relapse in weight‐restored AN. © 2008 by Wiley Periodicals, Inc.

Psychosocial predictors of weight loss and psychological adjustment following bariatric surgery and a weight‐loss program: The mediating role of emotional eating
Authors: Canetti Laura , Berry Elliot M. , Elizur Yoel 
Published: October 2008

AbstractObjective:To examine a structural equation model of the effects of personal and interpersonal factors on treatment outcome of bariatric surgery and weight‐loss program.Method:Forty‐four participants of the surgery group and 47 participants of the diet group completed questionnaires before treatment and 1 year afterward. Predictor measures are as follows: social support, motivation for control, sense of control, self‐esteem, neuroticism, fear of intimacy, and emotional eating (EE).Outcome measures:Weight loss, qual‐ity of life, and mental health.Results:Neurotic predisposition (NP), a latent variable indicated by neuroticism, low self‐esteem, and fear of intimacy, had an effect on weight loss that was fully mediated by EE. NP also had an effect on quality of life improvement that was fully mediated by EE and weight loss in both treatment groups.Discussion:Both NP and EE predict outcome of obesity treatments, but EE is the more proximal variable that mediates the effect of NP. © 2008 by Wiley Periodicals, Inc.

Published: October 2008

AbstractObjective:This study examined the effect of the placement of a warning text before visiting proanorexia websites on actual access of these websites.Method:A separate webpage with a warning text aiming at first‐time visitors was placed before each proanorexia website hosted by a Dutch Internet provider. During the research period of 1 year, the numbers of hits at the warning webpage were registered together with the numbers of hits at the underlying proanorexia website.Results:Of the total number of hits registered at the warning webpage, about two‐third of the visitors were registered at the underlying proanorexia website. This indicates that about one‐third of the visitors did not continue their visit to a proanorexia website after being exposed to the warning text.Discussion:Placement of a warning text before proanorexia websites appears a promising strategy in holding back potential visitors. © 2008 by Wiley Periodicals, Inc.

Published: October 2008

AbstractObjective:To measure the cooccurrence of obesity and eating disorder (ED) behaviors in the South Australian population and assess the change in level from 1995 to 2005.Method:Two independent cross‐sectional single stage interview based population surveys were conducted a decade apart. Self‐reported height, weight, ED behaviors, and sociodemographics were assessed. Changes between the two time points were analyzed.Results:From 1995 to 2005 the population prevalence of comorbid obesity and ED behaviors increased from 1 to 3.5%. Comorbid obesity and ED behaviors increased more (prevalence odds ratio (POR) = 4.5; 95% confidence interval (CI) = 95% CI = [2.8, 7.4]; p < .001) than either obesity (POR = 1.6; 95% CI = [1.3, 2.0]; p < .001) or ED behaviors (POR = 3.1; 95% CI = [2.3, 4.1]; p < .001) alone.Discussion:Comorbid obesity and ED behaviors are an increasing problem in our society. Prevention and treatments efforts for obesity and EDs must consider and address this increasing comorbidity. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009

AbstractObjective:The Yale–Brown–Cornell Eating Disorder Scale (YBC‐EDS) assesses eating disorder preoccupations, rituals, and symptom severity. This study examines the YBC‐EDS in relation to eating disorder psychopathology, obsessionality, and impul‐sivityvariables in women with anorexia nervosa (AN) and sensitivity of the YBC‐EDS to change after psychotherapy.Method:Participants were 56 women with “spectrum” AN (14.5 < BMI < 19). Variables examined in relation to the YBC‐EDS were as follows: eating pathology, obsessionality (obsessive compulsive disorder and personality diagnoses, perfectionism), and impulsivity (borderline personality, impulsive traits, and behaviors). YBC‐EDS scores were examined pre‐ and post‐treatment.Results:Eating Disorder Examination scores most strongly predicted the YBC‐EDS. As expected, perfectionism was significantly associated, but so was impulsivity. YBC‐EDS scores were significantly different in those with good versus poor global outcome after therapy. Unexpectedly, maximum lifetime BMI was correlated with the YBC‐EDS.Discussion:The YBC‐EDS most strongly measured eating disorder severity and reflected change after psychotherapy for AN. © 2008 by Wiley Periodicals, Inc.
