Published: March 2009

AbstractIn support of a split: A water oxidation catalyst based on ruthenium bis‐(2‐pyridyl)pyrazole anchored on rutile TiO2 was prepared. The performance of this new material with regard to its capacity to catalytically oxidize water to molecular oxygen in a heterogeneous phase was evaluated.magnified imageTwo organic ligands based on bis‐(2‐pyridyl)pyrazole (Hbpp) functionalized with a para‐methylenebenzoic acid (Hbpp‐Ra) or its ester derivative (Hbpp‐Re) were prepared and characterized. The ester‐functionalized ligand was then used to prepare a series of related dinuclear ruthenium complexes of general formula [RuII2(L‐L)(bpp‐Rn)(trpy)2]m+ (L‐L=μ‐Cl, μ‐acetato, or (H2O)2; n=e or a; trpy=2,2′:6′,2′′‐terpyridine; m=2 or 3). The complexes were characterized in solution by 1D and 2D NMR spectroscopy, UV/Vis spectroscopy, and electrochemical techniques. The [RuII2(μ‐Cl)(bpp‐Re)(trpy)2](PF6)2 complex was further characterized in the solid state by X‐ray diffraction. The complexes containing the free carboxylic acid ligand were anchored onto rutile TiO2 and treated with 0.1 M triflic acid solution to generate the homologous water‐oxidation catalysts TiO2‐[RuII2(H2O)2(bpp‐Ra)(trpy)2]2+. This new hybrid material catalytically oxidizes water to molecular oxygen in a heterogeneous manner using CeIV as chemical oxidant. The generation of molecular oxygen is accompanied by the formation of carbon dioxide as well as some leaching of the Ru catalyst.
Olfactory association learning and brain‐derived neurotrophic factor in an animal model of early deprivation
Authors: Zimmerberg Betty , Foote Hannah E. , Van Kempen Tracey A. 
Published: March 2009

AbstractAnimal models can serve to explore neural mechanisms underlying the effects of stressful early experiences on behaviors supporting attachment. Neonatal rats primarily use olfaction for attachment, and Brain‐Derived Neurotrophic Factor (BDNF) may be a key transcription target in olfactory association learning. In this experiment, neonatal male and female rats were isolated individually for 3 hr daily in the first week of life while their dams were left with partial litters (Early Deprivation, ED) or remained undisturbed (Control). At 1 week of age, subjects were tested using a 2‐day classical conditioning paradigm. The conditioned group (O/M) was exposed to a novel odor paired with a milk infusion. Three additional groups included an unpaired odor and milk exposure group (O/M unP), an odor exposure alone group (O/NM), and neither an odor nor a milk group (NO/NM). Learning the odor association, as revealed in a position preference for the novel odor, was accompanied by an increase in hippocampal BDNF in O/M subjects from undisturbed Control litters. BDNF levels were also positively related to degree of preference for the odor in the O/M Control group. ED subjects did not make the classically conditioned odor association and did not show an increase in hippocampal BDNF. ED increased BDNF levels in the olfactory bulb compared to Controls regardless of training group; individual levels were not correlated with performance because samples were pooled. These results suggest that changes in the transcription of BDNF may underlie some of the long‐term consequences of the early stress of maternal separation. © 2009 Wiley Periodicals, Inc.

Interpersonal interactions on online forums addressing eating concerns
Authors: Ransom Danielle C. , La Guardia Jennifer G. , Woody Erik Z. , Boyd Jennifer L. 
Published: March 2009

AbstractObjective:Although some research suggests that online eating disorder forums promote “pro‐eating‐disorder” lifestyles and discourage recovery, other research suggests that such forums are an important source of interpersonal support. The current study extends this research by exploring the positive and negative behaviors encouraged on these forums and by comparing forum members' perceptions of support received from online and offline relationships to support received in relationships of age‐matched controls.Method:In a survey of 60 forum members, we assessed information exchanged and support provided on eating disorder forums. Further, we assessed perceptions of social support for general and specific life concerns in this group of forum members as well as 64 age‐matched university controls.Results:Results show that both adaptive and maladaptive behaviors are encouraged on the forums, and that this encouragement has some influence on forum members trying out these behaviors. Overall, forum members reported receiving less support for their eating concerns as compared to their general life stressors, and they perceived less support for both their general concerns and eating concerns in their offline relationships as compared to their online forum relationships. Moreover, forum members reported receiving less support from their offline relationships as compared to support received in relationships by age‐matched controls.Discussion:Forum members perceive less support in their important relationships than other peers do, and they seek out and participate in forums as a means of attaining greater social support. However, our research suggests that these forums also encourage dysregulated eating behaviors. Implications of online forum support and its impact on recovery are discussed further. © 2009 by Wiley Periodicals, Inc. Int J Eat Disord, 2010

AbstractObjective:Measurement of disease‐related impairment and distress is central to diagnostic, therapeutic, and health policy considerations for eating disorders across diverse populations. This study evaluates psychometric properties of a translated and adapted version of the Clinical Impairment Assessment (CIA) in an ethnic Fijian population.Method:The adapted CIA was administered to ethnic Fijian adolescent schoolgirls (N = 215). We calculated Cronbach's α to assess the internal consistency, examined the association between indicators of eating disorder symptom severity and the CIA to assess construct and criterion validity, and compared the strength of relation between the CIA and measures of disordered eating versus with measures of generalized distress.Results:The Fijian version of the CIA is feasible to administer as an investigator‐based interview. It has excellent internal consistency (α = 0.93). Both construct and criterion validity were supported by the data, and regression models indicated that the CIA predicts eating disorder severity, even when controlling for generalized distress and psychopathology.Discussion:The adapted CIA has excellent psychometric properties in this Fijian study population. Findings suggest that the CIA can be successfully adapted for use in a non‐Western study population and that at least some associated distress and impairment transcends cultural differences. © 2009 by Wiley Periodicals, Inc.

Perfectionism across stages of recovery from eating disorders
Authors: Bardone‐Cone Anna M. , Sturm Katrina , Lawson Melissa A. , Robinson D. Paul , Smith Roma 
Published: March 2009

AbstractObjective:This study examined perfectionism in relation to recovery from eating disorders by comparing different conceptualizations of perfectionism across healthy controls and fully recovered, partially recovered, and active eating disorder cases, where full recovery was defined using physical, behavioral, and psychological indices.Method:Participants were primarily young adult females; 53 active eating disorder cases, 15 partially recovered cases, 20 fully recovered cases, and 67 healthy controls. Participants completed questionnaires assessing trait perfectionism, perfectionistic self‐presentation style, and frequency of perfectionism cognitions, as well as a diagnostic interview to determine lifetime and current eating disorder diagnoses.Results:A robust pattern emerged whereby the fully recovered individuals and healthy controls had similar levels of perfectionism that were significantly lower than the perfectionism levels of the partially recovered and active individuals with eating disorder, who were comparable to each other.Discussion:These findings have implications for more clearly defining eating disorder recovery and for the role perfectionism may play in achieving full recovery. © 2009 by Wiley Periodicals, Inc.

Published: March 2009

AbstractObjective:To study the course and outcome of patients with eating disorder detected in primary care.Method:General practitioners (GP's) provided information on the course and outcome of eating disorders in patients (n = 147) diagnosed with anorexia nervosa (AN) or bulimia nervosa (BN) identified during a Dutch nationwide primary care‐based incidence study. The research team determined the outcome based on the data provided by the GP's. The mean duration of the follow‐up was 4.8 years.Results:About 57% of the patients initially diagnosed with AN and 61% of those diagnosed with BN were fully recovered. AN binge/purge subtype (ANBP) demonstrated the most extended median survival time of all diagnostic subgroups (the point at which half of the group has reached full recovery). Diagnostic crossover was low. A younger age at detection predicted recovery at outcome for AN and BN. One patient (AN) died.Discussion:The results of this study on differences in outcome and low crossover support the diagnostic distinction between AN and BN in the DSM‐IV. Early detection is of major importance for a favorable outcome. © 2009 by Wiley Periodicals, Inc. Int J Eat Disord, 2010
Robust estimation of driver posture in the presence of lighting changes
Authors: Takahashi Daisuke , Okamoto Noriyoshi 
Published: March 2009

AbstractIn this study, we aim for posture estimation that considers the influence of lighting changes. We propose an algorithm that considers a bad condition by using 3D data and 2D animation. The decrease of the gaze forward rate caused by the psychological condition and ensuing tiredness is a problem of safety driving. There is a technique for detecting looking away and looking down for a long time by estimation of the driver's face posture from the image as this method of settlement. However, the conventional technique uses images in the posture estimation, which has the problem of a strong influence on the lighting condition and the size of the database. This technique pays too much attention to lighting changes 3D data and texture information. Making the database solved these problems; the accuracy average obtained was 89% and the estimation speed was 6 f/s. © 2009 Wiley Periodicals, Inc.

A Web page that provides map‐based interfaces for VRML/X3D content
Authors: Miyake Yoshihiro , Suzaki Kenichi , Araya Shinji 
Published: March 2009

AbstractThe electronic map is very useful for navigation in the VRML/X3D virtual environments. So far various map‐based interfaces have been developed. But they are lacking for generality because they have been separately developed for individual VRML/X3D contents, and users must use different interfaces for different contents. Therefore, we have developed a Web page that provides a common map‐based interface for VRML/X3D contents on the Web. Users access VRML/X3D contents via the Web page. The Web page automatically generates a simplified map by analyzing the scene graph of downloaded contents, and embeds the mechanism to link the virtual world and the map. An avatar is automatically created and added to the map, and both a user and its avatar are bidirectionally linked together. In the simplified map, obstructive objects are removed and the other objects are replaced by base boxes. This paper proposes the architecture of the Web page and the method to generate simplified maps. Finally, an experimental system is developed in order to show the improvement of frame rates by simplifying the map. © 2009 Wiley Periodicals, Inc.

Vibration suppression control of redundant manipulator with flexible structure by considering nullspace motion
Authors: Sasaki Koji , Murakami Toshiyuki 
Published: March 2009

AbstractA redundant manipulator is useful for posture control while maintaining the desired end‐effector position by using its redundancy. This makes it possible to perform agile motions such as obstacle avoidance while achieving the target task. However, as the number of degrees of freedom of motion increases, the stiffness of the redundant manipulator decreases, which induces unacceptable vibration in manipulator motion. To address this issue, this paper describes a strategy of vibration suppression by using a workspace observer and resonance ratio control based on nullspace control. The validity of the proposed approach is confirmed by simulations and experiments. © 2009 Wiley Periodicals, Inc.

Published: March 2009

AbstractA high‐accuracy modeling methodology for electrical characteristics of transmission electrodes on SAW substrates is established. In order to design SAW filter accurately, it is necessary to extract precise SAW material parameters from the measurement value of the reference SAW resonator. When measuring the SAW resonator, transmission lines are needed for feeding to contact probes. De‐embedding procedure, which removes the influence of transmission lines, is very important for accurate characterization of the SAW resonator.In this paper, we apply the improved de‐embedding procedure using Short, Open, and Thru calibration patterns. The de‐embedded transmission line is separated in four parts and extracted the RLGC equivalent circuit model for each part. Furthermore, we derive the frequency characteristic of resistance element of the transmission line. Finally, de‐embedding the transmission line accurately, we can get intrinsic characteristic of the SAW resonator. This method must be very useful to extract SAW material parameters and we can design SAW filters more effectively. © 2009 Wiley Periodicals, Inc.

Published: March 2009

AbstractSingle‐component molecular conductors [M(tmstfdt)2] (M = Ni, Au; tmstfdt = trimethylenediselenadithiafulvalenedithiolate) substituted with Se atoms are prepared and found to be isostructural with [M(tmdt)2] (M = Ni, Au; tmdt = trimethylenetetrathiafulvalenedithiolate). Measurements of the electrical conductivity and magnetic susceptibility of [Ni(tmstfdt)2] show that it has essentially metallic properties down to low temperatures. The resistivity measurements of [Au(tmstfdt)2] suggest it undergoes a metal‐insulator phase transition at around 100 K. Magnetic susceptibility and ESR measurements of [Au(tmstfdt)2] indicate that it undergoes a magnetic transition at around 5 K, which is much lower than theantiferromagnetic (AF) phase‐transition temperature of [Au(tmdt)2] (110 K).

Concave 1,10‐Phenanthrolines as Ligands for Cyclopropanations – Towards a Deeper Understanding of the Stereoselectivity
Authors: Eggers Friederike , Lüning Ulrich 
Published: March 2009

AbstractFour new mono‐ and bimacrocyclic 1,10‐phenanthrolines – 3b and 4a–c – containing aryl bridgeheads have been synthesised. The etherification of the aryl bridgeheads was accomplished by Williamson or Mitsunobu reactions. A key step in the synthesis of the macrocyclic phenanthrolines 3 and 4 is the Suzuki coupling of 2,9‐diiodo‐1,10‐phenanthroline (12) with the appropriately substituted boronic acids 17 and 20. Ring‐closing metathesis and hydrogenation completed the synthesis. The resulting macrocyclic 1,10‐phenanthrolines 3b and 4a–c were tested as ligands in a copper(I)‐catalysed stereoselective cyclopropanation.(© Wiley‐VCH Verlag GmbH & Co.

Lipophilic Thioglycosides for the Solution‐Phase Synthesis of Oligosaccharides Using Biphasic Liquid‐Liquid Separation
Authors: Encinas Lourdes , Chiara Jose Luis 
Published: March 2009

AbstractA simple “heavy” lipophilic tag readily prepared from inexpensive gallic acid can greatly simplify the purification steps in oligosaccharide synthesis through liquid‐liquid extraction (LLE) using two immiscible organic solvents. By introducing the tag at the anomeric position of the carbohydrate acceptor, this simple LLE purification can be advantageously carried out at each step throughout the synthetic route. We have developed efficient tagging and detagging procedures and have shown that a single tag is sufficient to ensure a high affinity of the tagged molecule for alkane solvents even in the case of highly polar substrates.(© Wiley‐VCH Verlag GmbH & Co.

The impact of exchange programs on the integration of the hostgroup into the self‐concept
Authors: Sassenberg Kai , Matschke Christina 
Published: March 2009

AbstractTwo studies analyzed the impact of international exchange programs on students' identity development. More precisely, the authors predict that exchange students integrate the host society (hostgroup) into their self‐concept during an exchange year. Study 1 found a stronger social identification with the hostgroup and higher commitment for former exchange students than for future exchange students. Study 2 replicated the difference between former and future exchange students and found in addition that both former and future exchange students had a stronger identification and commitment in comparison to a control group that did neither take part in nor apply for an exchange program. Moreover, in this study the inclusion of the hostgroup into the self‐concept was assessed via a response time paradigm. The results indicate that former and future exchange students have a stronger association between the self and the hostgroup than the control sample, but no difference between former and future exchange students was found. The results provide evidence for the impact of interest in and actual intensive intergroup contact on students' self‐concept. Copyright © 2009 John Wiley & Sons, Ltd.
Selecting explanations from causal chains: Do statistical principles explain preferences for voluntary causes?
Authors: Hilton Denis J. , McClure John , Sutton Robbie M. 
Published: March 2009

AbstractWe investigate whether people prefer voluntary causes to physical causes in unfolding causal chains and whether statistical (covariation, sufficiency) principles can predict how people select explanations. Experiment 1 shows that while people tend to prefer a proximal (more recent) cause in chains of unfolding physical events, causality is traced through the proximal cause to an underlying distal (less recent) cause when that cause is a human action. Experiment 2 shows that causal preference is more strongly correlated with judgements of sufficiency and conditionalised sufficiency than with covariation or conditionalised covariation. In addition, sufficiency judgements are partial mediators of the effect of type of distal cause (voluntary or physical) on causal preference. The preference for voluntary causes to physical causes corroborates findings from social psychology, cognitive neuroscience and jurisprudence that emphasise the primacy of intentions in causal attribution processes.

Rule transgressions in groups: The conditional nature of newcomers' willingness to confront deviance
Authors: Jetten Jolanda , Hornsey Matthew J. , Spears Russell , Haslam S. Alexander , Cowell Eleanor 
Published: March 2009

AbstractWe provide evidence that, compared to old‐timers, newcomers' intentions to confront deviants are more sensitive to the social context when confronted with rule‐violations. Female rugby players (N = 71) were asked for their disapproval of, and willingness to sanction, ingroup and outgroup members who broke important rules in rugby. We also manipulated the status of the audience and found that newcomers were more likely to confront deviants when the audience was high status, and when there was little risk of alienating other ingroup members. In contrast, old‐timers expressed relatively high intentions to confront deviants regardless of the context. Discussion focuses on the idea that newcomers resiled from confronting deviants when an ingroup rule‐breaker had to be directly confronted, presumably because the perceived costs of doing so exceeded the potential benefits of ingratiating oneself to the high‐status audience.

On the robustness of the group reference effect
Authors: Bennett Mark , Allan Susan , Anderson Jennifer , Asker Nasreen 
Published: March 2009

AbstractExtending the self‐reference effect to the level of group identities, previous research has shown that participants' encoding of trait adjectives with reference to ingroups facilitates recall relative to a control condition in which judgments are made about adjectives' meanings. We contend that this experimental comparison may have exaggerated the extent of the group reference effect. Two studies are reported that examine this contention. In Study 1 participants encoded adjectives with reference to an ingroup, an outgroup or to its semantic properties. Study 2 was nearly identical but required that adjectives be encoded with reference to an ingroup, the personal self or a specific person other than the self. Notwithstanding the use of more stringent controls, both studies provided evidence for the group reference effect. Copyright © 2009 John Wiley & Sons, Ltd.
