Impact of interactive school‐based media literacy lessons for reducing internalization of media ideals in young adolescent girls and boys
Authors: Wilksch Simon M. , Tiggemann Marika , Wade Tracey D. 
Published: March 2006

AbstractObjective:The primary objective of the current study was to examine the efficacy of single media literacy lessons in reducing media internalization in young adolescents.Method:Eleven classes of 237 students (100 girls and 137 boys; mean age = 13.79 years, SD = .42) randomly received 1 of 6 lessons. Eating disorder risk factors were assessed at baseline, and the Sociocultural Attitudes Towards Appearance Questionnaire‐3 (SATAQ‐3) was used to assess media internalization postintervention.Results:At postintervention, boys had significantly lower SATAQ‐3 scores on 4 of the 5 subscales (effect sizes = .42–.71), whereas girls had significantly lower scores on 1 subscale (effect size = .54). Higher baseline levels of dietary restraint, magazines bought/read, and perceived sociocultural pressure predicted smaller reductions in boys' scores, whereas depression predicted smaller reductions in girls' scores.Conclusion:The current study provides support that boys be included in eating disorder prevention programs and that media literacy may represent a promising prevention approach. © 2006 by Wiley Periodicals, Inc.

Authors: Larsen Junilla K. , Geenen Rinie , van Ramshorst Bert , Brand Nico , Hox Joop J. , Stroebe Wolfgang , van Doornen Lorenz J.P. 
Published: March 2006

AbstractObjective:The current study sought to find indications for the appropriateness of a model in which eating patterns and exercise beliefs influence binge eating and physical exercise, respectively, that, in turn, influence outcome after gastric banding for severe obesity.Method:Participants were 157 patients (144 females, 13 males) who completed questionnaires approximately 34 months (range = 8–68 months) after laparoscopic adjustable gastric banding (LAGB).Results:Our data showed a well‐fitting model in which external and emotional eating were associated with outcome through binge eating. Several exercise beliefs were associated with physical exercise, but physical exercise was not associated with weight loss or physical health.Conclusion:Binge eating was related more strongly to the outcome after gastric banding than physical exercise. Future research should examine whether a strong focus on the management of binge eating and external and emotional eating could improve the outcome of morbidly obese patients with unsuccessful weight outcome after obesity surgery. © 2006 by Wiley Periodicals, Inc.

Authors: Frisch Maria J. , Herzog David B. , Franko Debra L. 
Published: March 2006

AbstractObjective:The current study describes residential treatment for eating disorders in the United States.Method:A national study involving 22 residential eating disorder treatment programs was conducted using a survey to determine treatment program descriptions and trends. Data from 19 respondents, representing 86% of all residential treatment programs in the United States, were examined.Results:Residential treatment options for individuals with anorexia nervosa and bulimia nervosa are becoming increasingly more common. A wide variety of techniques and methods are employed in the treatment of individuals with eating disorders in residential treatment programs. The average length of stay in treatment was 83 days, with an average cost per day of $956 U.S. dollars.Conclusion:The residential treatment of individuals with eating disorders is a growing, variable, and largely unregulated enterprise. Future research is needed to focus on quantifying treatment program effectiveness in the residential treatment of individuals with eating disorders. © 2006 by Wiley Periodicals, Inc.

Development of the eating disorder recovery self‐efficacy questionnaire
Authors: Marinilli Pinto Angela , Guarda Angela S. , Heinberg Leslie J. , DiClemente Carlo C. 
Published: March 2006

AbstractObjective:The purpose of the current investigation was to develop and validate the Eating Disorder Recovery Self‐Efficacy Questionnaire (EDRSQ), a self‐report measure of self‐efficacy to recover from an eating disorder.Method:Participants were 116 female patients with anorexia nervosa, bulimia nervosa, or a subthreshold eating disorder treated at an eating disorder clinic. Patients completed the EDRSQ and measures of eating disorder symptoms and depression.Results:The EDRSQ contains two internally consistent factors, Normative Eating Self‐Efficacy and Body Image Self‐Efficacy. Moderate to large correlations between EDRSQ subscales and measures of eating disorder pathology support the convergent validity of the EDRSQ. The EDRSQ demonstrates theoretically consistent relations with constructs that are related to but distinct from self‐efficacy. Discriminant validity is reflected in small correlations between EDRSQ subscales and measures of general psychological correlates of disordered eating.Conclusion:The EDRSQ is a psychometrically sound measure to assess self‐efficacy in patients with a range of eating disorder diagnoses. © 2006 by Wiley Periodicals, Inc.

Nonreporting of body mass index: A research note on the interpretation of missing data
Authors: Tiggemann Marika 
Published: March 2006

AbstractObjective:The aim of the study was to investigate the correlates of missing values on body mass index (BMI), with a view to distinguishing between potential hypotheses as to their origin.Method:Participants were 1,452 secondary school students who completed questionnaire measures of BMI, perceived weight, body dissatisfaction, appearance investment, and eating disorder symptomatology.Results:More than one fourth of the sample had missing values on height or weight, the highest proportion of missing data occurring among older girls. Missing status on weight was associated with poorer body image and a greater investment in appearance for girls, but not for boys.Conclusion:It was concluded that the pattern of results was most consistent with the hypothesis that missing values resulted from motivated nonresponding. More generally, the study provides an illustration of the usefulness of treating missing values as data in their own right. © 2006 by Wiley Periodicals, Inc. Int J Eat Disord 2006.
Use of extreme weight control behaviors with and without binge eating in a community sample: Implications for the classification of bulimic‐type eating disorders
Authors: Mond Jonathan , Hay Phillipa , Rodgers Bryan , Owen Cathy , Crosby Ross , Mitchell James 
Published: March 2006

AbstractObjective and Method:To inform the classification of bulimic‐type eating disorders not meeting formal diagnostic criteria for bulimia nervosa (BN), levels of eating disorder psychopathology and functional impairment associated with subjective and objective bulimic episodes (SBEs and OBEs) and purging and nonpurging methods of weight control were examined in a large community‐based sample of women (n = 5,232).Results:Participants who reported recurrent bulimic episodes had significantly higher levels of eating disorder psychopathology and functional impairment than those who did not and this was the case whether the episodes were objective or subjective. Similarly, participants who reported the use of extreme weight control behaviors had higher levels of eating disorder psychopathology and functional impairment than those who did not, and this was the case whether purging or nonpurging behaviors were employed. The combination of bulimic episodes and extreme weight control behaviors was associated with particularly high levels of eating disorder psychopathology and functional impairment.Conclusion:The combination of bulimic episodes, objective or subjective, and extreme weight control behaviors, purging or nonpurging, is significant in terms of impairment in psychosocial functioning among individuals affected by eating disorders not meeting formal diagnostic criteria for BN. The combination of SBEs and extreme weight control behaviors, in particular, warrants further investigation. © 2006 by Wiley Periodicals, Inc. Int J Eat Disord 2006.
A longitudinal study investigating disordered eating during the transition to motherhood among Chinese women in Hong Kong
Authors: Lai Beatrice Pui‐yee , Tang Catherine So‐kum , Tse Winni Kwok‐lai 
Published: March 2006

AbstractObjective:The current longitudinal study explored the prevalence and psychosocial factors of disordered eating among new Chinese mothers in Hong Kong.Method:Self‐report questionnaires on bulimic symptoms and pregnancy‐related factors were collected at both prenatal and postnatal periods from 131 Chinese women.Results:Participants reported significantly more severe disordered eating in the postnatal than in the prenatal period, with percentages being 19.08% and 8.4%, respectively, using the Eating Disorder Inventory‐2. Results revealed that prenatal disordered eating, weak maternal‐fetal attachment, a low level of instrumental spousal support during pregnancy, postnatal depressive symptoms, and a poor mother‐infant relationship were significantly related to disordered eating at 6 months postchildbirth.Conclusion:Findings suggested that the transition to motherhood is a period of stress that may either precipitate or exacerbate disordered eating. © 2006 by Wiley Periodicals, Inc.

Misuse of laxatives among adult outpatients with eating disorders: Prevalence and profiles
Authors: Bryant‐Waugh Rachel , Turner Hannah , East Philippa , Gamble Caroline , Mehta Rajnikant 
Published: March 2006

AbstractObjective:The current study investigated the prevalence of laxative misuse among adult outpatients with eating disorders, distinguished demographic and psychobehavioral profiles of laxative misusers, identified specific predictors of laxative misuse, and explored whether prevalence rates and psychobehavioral profiles differ across eating disorder diagnoses.Method:Data were collected for 201 consecutive patients. Laxative misusers and nonmisusers were compared on demographic variables, measures of eating‐related and weight‐related behaviors and cognitions, and general psychopathology.Results:Fifty‐three (26.4%) patients had misused laxatives in the month before assessment. Laxative misusers scored significantly higher than nonmisusers on measures of anorexic behaviors and cognitions, restraint, and weight and shape concerns. They also displayed higher levels of depression and self‐directed hostility. Laxative misuse was specifically predicted by anorexic behaviors and depression. Across diagnoses, proportions of misusers versus nonmisusers were similar.Conclusion:Laxative misuse remains prevalent among adult outpatients and is associated with increased severity of clinical presentation, regardless of the eating disorder diagnosis. © 2006 by Wiley Periodicals, Inc.

Finding all solutions of weakly nonlinear equations using the dual simplex method
Authors: Yamamura Kiyotaka , Tanaka Katsumasa 
Published: March 2006

AbstractRecently, efficient algorithms have been proposed for finding all solutions of nonlinear equations using linear programming (LP). These algorithms are based on a simple test (termed the LP test) for nonexistence of a solution to a system of nonlinear equations in a given region. In the LP test, a system of nonlinear equations is transformed into an LP problem by surrounding component nonlinear functions by rectangles or right‐angled triangles. In this paper, an efficient algorithm is proposed for finding all solutions of weakly nonlinear equations, where component nonlinear functions are surrounded by parallelograms and then the dual simplex method is applied to the LP problem. Numerical examples are given to confirm the effectiveness of the proposed algorithm. © 2006 Wiley Periodicals, Inc.

Analytical correction methods for aperture and attenuation effects in SPECT
Authors: Ishikawa Akira , Ogawa Koichi 
Published: March 2006

AbstractThis paper is concerned with the lowering of spatial resolution by γ ray attenuation and the collimator aperture, which are serious factors degrading the quantitative performance of SPECT (single‐photon emission CT). The limit of analytical correction is investigated from the viewpoint of the aperture angle and noise. The methods considered in this paper are the analytical attenuation correction proposed by Kudo and Saito and the analytical aperture correction based on the stationary phase principle proposed by Lewitt and colleagues. Both of these methods are intended to correct projection data affected by attenuation and aperture blur in the Fourier space. Simulation results show that the correction for the attenuation and the aperture is effective if the single‐sided aperture is up to 1°. It is also shown that the statistical noise should be carefully handled in applying the correction. © 2006 Wiley Periodicals, Inc.

Authors: Ogawa Naoko , Sakaguchi Yutaka , Namiki Akio , Ishikawa Masatoshi 
Published: March 2006

Abstract“Dynamics matching” is a design concept in sensory‐motor fusion systems, where the performance is maximized by adjustment of the dynamics of the system under the physical and computational constraints. This paper models dynamics matching as an optimization problem and constructs an adaptive acquisition algorithm. A numerical experiment on the target‐tracking task using active vision is presented as an example, and it is shown that a reasonable solution is acquired by the proposed approach. © 2006 Wiley Periodicals, Inc.

Time‐series data server optimized for multichannel and real‐time processing
Authors: Goto Hiroyuki 
Published: March 2006

AbstractSince there are a considerable number of earthquakes and active volcanoes in Japan, it is important to install high‐accuracy seismic monitoring equipment and to develop systems that can process observed data efficiently. In the field of seismic data processing, specific requirements such as multichannel and on‐demand/real‐time processing are essential, whereas they are not so significant in other time‐series data. Since conventional systems cannot fulfill such requisites, a client/server system is newly developed. It provides a unified solution for delivering the seismic data to the client side, whether it is used for real‐time monitoring or for on‐demand printing. © 2006 Wiley Periodicals, Inc.

A New and Fast Synthesis of Nanosized LiFePO4 Electrode Materials
Authors: Caballero Alvaro , Cruz‐Yusta Manuel , Morales Julián , Santos‐Peña Jesús , Rodríguez‐Castellón Enrique 
Published: March 2006

AbstractLiFePO4 has been prepared as highly crystalline nanoparticles (approx. 80 nm in diameter) of well‐defined shape by heating a mixture containing lithium acetylacetonate, iron oxalate, ammonium hydrogen phosphate and oxalic acid under argon at 550 °C for 2 h. The resulting solid contains about 6 % magnetite (Fe3O4) as an impurity. Despite its small particle size, this nanomaterial exhibits relatively poor electrochemical performance in lithium cells owing to its lack of electronic conductivity. Its electrochemical response contrasts with previously reported data for nano‐LiFePO4 materials prepared at such low temperatures. In order to overcome its lack of conductivity, the compound was treated with a copper precursor. The copper phosphate nanocomposite thus obtained exhibits improved electrochemical performance in terms of capacity and cycling life in lithium cells. Thus Cu‐LiFePO4‐based cells deliver capacity values close to 80 mAh g–1 over at least 50 cycles under a C/10 regime. These values testify to the usefulness of the proposed synthetic method for preparing nanoparticulated lithium phosphate‐based electrodes. (© Wiley‐VCH Verlag GmbH & Co.

Published: March 2006

AbstractThe suitability of bimetallic coordination compounds in the systems Cu/Zn/CN and Cu/Zn/CN/ethylenediamine as precursors for CuO/ZnO was explored. The kinetic and thermodynamic equilibria in these systems are discussed. The introduction of ethylenediamine led to crystalline precursorcompounds, and the bimetallic coordination compounds[Zn(en)]2[Cu2(CN)6] and [Zn(en)3]6[Cu2(CN)7]2[Cu(CN)3]·8.4H2O were structurally characterised. The oxide mixtures of CuO/ZnO, prepared by mild thermolysis of the precursor compounds, were tested for their catalytic activity in the formation of methanol from synthesis gas, i.e. CO/CO2/H2. While the oxide mixtures from Zn[Cu(CN)3] were not catalytically active, the oxide mixtures derived from the crystalline compounds with ethylenediamine as the ligand had about 20–30 % of the activity of an industrial methanol catalyst. This underscores the importance of the origin of the catalyst, i.e. the dependence of its activity from the structure of its precursor. (© Wiley‐VCH Verlag GmbH & Co.

AbstractReactions of the 11‐vertex nido‐tricarbollide anions [7,8,9‐C3B8H11]– (2a) and [7,8,10‐C3B8H11]– (3) with [Cb*Co(MeCN)3]+ or [Cb*Co(C6H6)]+ (Cb* = C4Me4) afford the expected cobaltatricarbollides 1‐Cb*‐1,2,3,4‐CoC3B8H11 (4a) and 1‐Cb*‐1,2,3,5‐CoC3B8H11 (5), respectively. A similar reaction of the amino‐substituted anion [7‐tBuNH‐7,8,9‐C3B8H10]– (2b) is accompanied by polyhedral rearrangement even at room temperature, giving 1‐Cb*‐12‐tBuNH‐1,2,4,12‐CoC3B8H10 (7b). Complex 4a rearranges to the isomeric complex 5 at 110 °C and further to 1‐Cb*‐1,2,4,10‐CoC3B8H11 (6a) at 160 °C. The amino‐substituted derivative 1‐Cb*‐10‐tBuNH‐1,2,4,10‐CoC3B8H10 (6b) was obtained by isomerization of 7b at 160 °C. The observed rearrangement sequence for Cb*CoC3B8H11 correlates well with the relative stabilities of nonmethylated analogs estimated by DFT calculations. The structures of 4a and 7b were determined by X‐ray diffraction. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
Investigations into the Reactivity of Organoelement Gallium Subhalides – Syntheses of Bifunctional Digallium Carboxylate Iodides Possessing Bridged Ga–Ga Bonds and Terminal Iodine Atoms
Authors: Uhl Werner , El‐Hamdan Abdelhakim , Schindler Klaus Peter 
Published: March 2006

AbstractThe organoelement subhalide R2Ga2I2 (1) [R = C(SiMe3)3] reacted with one equivalent of different lithium carboxylates LiO2CR [R = ‐C6H5, ‐4‐Me3C–C6H4, ‐4‐BrC6H4, ‐3,5‐Me2C6H3, ‐CMe3] by the selective replacement of only one iodine atom. Bifunctional digallium compounds were formed, in which one chelating carboxylato group bridges the Ga–Ga bonds. Thus, both gallium atoms are coordinated to one carbon atom of the tris(trimethylsilyl)methyl groups and one oxygen atom of the chelating ligand, while only one is further attached to a terminal iodine atom. This asymmetric substitution pattern results in different coordination numbers of three and four for the gallium atoms. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)

Published: March 2006

AbstractHomoleptic NiII and FeII complexes of the “large‐surface” phenanthroline‐type ligand 1,12‐diazaperylene (dap), [Ni(dap)3](BF4)2 (1) and [Fe(dap)3](PF6)2 (2), respectively, were synthesized. In the crystal structure the complex cation [M(dap)3]2+ (M = Ni, Fe) exhibits C3 symmetry and interacts with three other cations by π‐π stacking. It forms a new metalla‐supramolecular assembly with a honeycomb structure containing nanochannels running parallel to the crystallographic c axis. Aggregation by π‐π stacking between metal complexes of “large‐surface” ligands should give new perspectives for inorganic supramolecular chemistry. (© Wiley‐VCH Verlag GmbH & Co.

Authors: Busca Patricia , McCort Isabelle , Prangé Thierry , Le Merrer Yves 
Published: March 2006

AbstractReceptor tyrosine kinases (RTKs) play an important role in signal transduction pathways, and in particular, FGFR3 is one of the four RTKs related to the fibroblast growth factor family. This paper describes the synthesis of C‐nucleosidic ATP mimics, as potential FGFR3 inhibitors, by nucleophilic epoxide ring‐opening followed by in situ O‐heterocyclization of 1,2:5,6‐dianhydro‐3,4‐di‐O‐benzyl‐D‐mannitol or L‐iditol. Cesium carbonate [Cs2CO3] was found to be the best catalyst for the reaction of purine derivatives with these bis‐epoxides. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)

Published: March 2006

AbstractA pyrolytic carbon (PC) film electrode was fabricated by the chemical vapor deposition (CVD) method. This report deals with the preparation, characterization and electrochemical behavior of this carbon film. Cyclic voltammetry, linear sweep voltammetry, Raman spectroscopy and scanning electron microscopy were employed to characterize the electrode. Low background current and capacitance were observed and the rate of charge transfer for Fe(CN)$\rm{ {_{6}^{3-/4-}}}$ redox couple was determined via cyclic voltammetry. Also the effect of the anodic activation on the electrochemical activity was evaluated and characterized with respect to the sequence of voltage applied to the electrode. The excellent electrochemical activity and low background current are the reasons why this electrode is attractive for electroanalysis measurements with lower detection limit.
Simultaneous and Direct Determination of Tryptophan and Tyrosine at Boron‐Doped Diamond Electrode
Authors: Zhao Guohua , Qi Yuan , Tian Yang 
Published: March 2006

AbstractA facile method for the simultaneous measurement of tryptophan (Trp) and tyrosine (Tyr) was firstly exploited at unmodified boron‐doped diamond (BDD) electrode. The experimental results indicated that by using differential pulse voltammetry, the oxidative peaks of these two kinds of amino acids could be completely separated at BDD electrode. The peak separation of Trp and Tyr was developed to be 0.64 V when Na2PO4/NaOH buffer solution with the optimized pH 11.2 was employed. The detection limit of Trp was obtained to be 1×10−5 M, while that of Tyr was achieved to be 1×10−6 M. The present method was also evidenced to be available to the determination of real samples of amino acids.
