Do People With Psychosis Have Specific Difficulties Regulating Emotions?
Authors: Lincoln Tania M. , Hartmann Maike , Köther Ulf , Moritz Steffen 
Published: September 2014

Difficulties in emotion regulation (ER) are present in psychotic disorders, but their precise nature is not yet fully understood and it is unclear which difficulties are unique to psychosis compared with other disorders. This study investigated whether ER difficulties in psychosis are more prominent for the ability to modify emotions or for the ability to tolerate and accept them. Furthermore, it investigated whether ER difficulties occur for sadness, anxiety, anger and shame likewise.ER skills were assessed in participants with psychotic disorders (n = 37), participants with depression (n = 30) and healthy controls (n = 28) using the Emotion Regulation Skill Questionnaire that asks participants to rate the intensity of different emotions over the past week and the skills employed to handle each of them.Compared with healthy controls, participants with psychosis showed reduced skills related to awareness, understanding and acceptance of potentially distressing emotions, but not in the ability to modify them. These differences remained significant after controlling for depression. Participants with psychosis showed reduced ER skills in regard to all of the assessed emotions compared with the healthy controls, despite the fact that they only reported sadness as being significantly more intense. The participants with depression showed a similar pattern of ER skills to the psychosis sample, although with a tendency towards even more pronounced difficulties.It is concluded that psychosis is characterized by difficulties in using specific ER skills related to awareness, understanding and acceptance to regulate anger, shame, anxiety and sadness. These difficulties are not unique to psychosis but nevertheless present a promising treatment target. Copyright © 2014 John Wiley & Sons, Ltd.Key Practitioner Message

The participants with psychosis found it more difficult to be aware of their emotions, to understand them and to accept them than the healthy control group. However, they reported equal skills when it came to actively modifying emotions.
The difficulties in emotion regulation reported by the participants with psychosis were comparable with those reported by the participants with depression, and they occurred for all types of negative emotions likewise.
The difficulties in using specific ER skills related to awareness, understanding and acceptance are a promising target for psychological treatment of psychosis.
Interventions that are aimed specifically at increasing these skills need to be further developed.
Complete Chemical Hydrolysis of Cellulose into Fermentable Sugars through Ionic Liquids and Antisolvent Pretreatments
Authors: Morales‐delaRosa Silvia , Campos‐Martin Jose M. , Fierro Jose L. G. 
Published: September 2014

AbstractThis work describes a relatively simple methodology for efficiently deconstructing cellulose into monomeric glucose, which is more easily transformed into a variety of platform molecules for the production of chemicals and fuels. The approach undertaken herein first involves the dissolution of cellulose in an ionic liquid (IL), followed by a second reconstruction step aided by an antisolvent. The regenerated cellulose exhibited strong structural and morphological changes, as revealed by XRD and SEM analyses. These changes dramatically affect the hydrolytic reactivity of cellulose with dilute mineral acids. As a consequence, the glucose yield obtained from the deconstructed–reconstructed cellulose was substantially higher than that achieved through hydrolysis of the starting cellulose. Factors that affect the hydrolysis reaction include the type of cellulose substrate, the type of IL used in pretreatment, and the type of acid used in the hydrolysis step. The best results were obtained by treating cellulose with IL and using phosphotungstic acid (0.067 mol L−1) as a catalyst at 413 K. Under these conditions, the conversion of cellulose was almost complete (>99 %), with a glucose yield of 87 % after only 5 h of reaction.
Control of Thickness and Chemical Properties of Atomic Layer Deposition Overcoats for Stabilizing Cu/γ‐Al2O3 Catalysts
Authors: O'Neill Brandon J. , Sener Canan , Jackson David H. K. , Kuech Thomas F. , Dumesic James A. 
Published: September 2014

AbstractWhereas sintering and leaching of copper nanoparticles during liquid‐phase catalytic processing can be prevented by using atomic layer deposition (ALD) to overcoat the nanoparticles with AlOx, this acidic overcoat leads to reversible deactivation of the catalyst by resinification and blocking of the pores within the overcoat during hydrogenation of furfural. We demonstrate that decreasing the overcoat thickness from 45 to 5 ALD cycles is an effective method to increase the rate per gram of catalyst and to decrease the rate of deactivation for catalysts pretreated at 673 K, and a fully regenerable copper catalyst can be produced with only five ALD cycles of AlOx. Moreover, although an overcoat of MgOx does not lead to stabilization of copper nanoparticles against sintering and leaching during liquid‐phase hydrogenation reactions, the AlOx overcoat can be chemically modified to decrease acidity and deactivation through the addition of MgOx, while maintaining stability of the copper nanoparticles.

Published: September 2014

SummaryMany ant species construct subterranean nests. The presence of their nests may explain soil respiration “hot spots”, an important factor in the high CO2 efflux from tropical forests. However, no studies have directly measured CO2 efflux from ant nests. We established 61 experimental plots containing 13 subterranean ant species to evaluate the CO2 efflux from subterranean ant nests in a tropical seasonal forest, Thailand. We examined differences in nest CO2 efflux among ant species. We determined the effects of environmental factors on nest CO2 efflux and calculated an index of nest structure. The mean CO2 efflux from nests was significantly higher than those from the surrounding soil in the wet and dry seasons. The CO2 efflux was species‐specific, showing significant differences among the 13 ant species. The soil moisture content significantly affected nest CO2 efflux, but there was no clear relationship between nest CO2 efflux and nest soil temperature. The diameter of the nest entrance hole affected CO2 efflux. However, there was no significant difference in CO2 efflux rates between single‐hole and multiple‐hole nests. Our results suggest that in a tropical forest ecosystem the increase in CO2 efflux from subterranean ant nests is caused by species‐specific activity of ants, the nest soil environment, and nest structure.
Practical Syntheses of Both Enantiomers of the Conformationally Restricted GABA Analogue cis‐(2‐Aminocyclobutyl)acetic Acid

Published: September 2014

AbstractTwo efficient routes have been established for the preparation of both enantiomers of cis‐(2‐aminocyclobutyl)acetic acid, a conformationally restricted analogue of GABA. Both procedures converged on the racemic N‐tert‐butoxycarbonyl derivative of the target compound, which was resolved through chiral derivatization with an oxazolidinone auxiliary, which also allowed determination of the absolute configuration of the new compounds. The first route involved the homologation of cis‐2‐aminocyclobutanecarboxylic acid, whereas the second route employed an intramolecular photocyclization protocol, which provided an expedient, cis‐selective access to the lactam form of the target structure.
Attentional bias for pain‐ and period‐related symptom words in healthy women who experienced a recent painful period
Authors: Schoth D.E. , Williams S. , Liossi C. 
Published: September 2014

AbstractBackgroundAttentional biases for pain‐related information have been commonly reported in patients with chronic pain. Biases may also exist in individuals who recently experienced an episode of acute clinical pain, although limited investigation has been conducted. The present study is the first to explore attentional biases in women who experienced recent menstrual pain.MethodsSeventy healthy women were recruited who experienced a regular menstrual cycle and a recent painful period. All participants completed a visual‐probe task with pain‐related and period‐related symptom words, which were presented at subliminal (14 ms, followed by nonsensical consonant letter string for 286 ms) and supraliminal (300 ms, 1250 ms) exposure durations. Participants then completed a series of self‐report measures, including a measure of cyclical perimenstrual symptoms.ResultsRecent menstrual pain severity was found to be significantly predictive of attentional bias towards pain‐related words presented for 1250 ms. However, no significant evidence of bias was found towards period‐related symptom words.ConclusionsPain‐related attentional biases are associated with recent menstrual pain severity. The experience and severity of pain, rather than its duration (i.e., whether pain is chronic or acute), may be the primary determinants of pain‐related attentional bias. Future research could explore attentional biases in acute clinical pain samples to confirm this notion.
The avoidance cocoon: Examining the interplay between attachment and caregiving in predicting relationship satisfaction
Authors: Reizer Abira , Ein‐Dor Tsachi , Shaver Phillip 
Published: September 2014

AbstractIn the present research, we examined the hypothesis that low avoidance enables the activation of the caregiving system, and therefore, among people low in avoidance, caregiving would affect relationship satisfaction, whereas among people high in avoidance, caregiving would not affect relationship satisfaction. One‐hundred seventy‐nine Israeli adults, currently involved in romantic relationships, participated in Study 1, in which we examined whether attachment avoidance moderated the associations between caregiving and relationship satisfaction. In Study 2, we sought to replicate this finding in a sample of Israeli couples (N = 194). Finally, in Study 3 (N = 44), we examined links between attachment, caregiving, and relationship satisfaction over a period of 1 year among Israeli married couples. Results indicated that caregiving deactivation and/or hyperactivation predicted lower relationship satisfaction, yet only among people low in avoidance or among people whose partners were low in avoidance. Results are discussed in relation to the important interplay between behavioral systems on individual and dyadic levels. Copyright © 2014 John Wiley & Sons, Ltd.
Methylmercury accumulation and elimination in mink (Neovison vison) hair and blood: Results of a controlled feeding experiment using stable isotope tracers

Published: September 2014

Abstract

Concentrations of metals in hair are used often to develop pharmacokinetic models for both animals and humans. Although data on uptake are available, elimination kinetics are less well understood; stable isotope tracers provide an excellent tool for measuring uptake and elimination kinetics. In the present study, methylmercury concentrations through time were measured in the hair and blood of mink (Neovison vison) during a controlled 60-d feeding experiment. Thirty-four mink were fed a standard fish-based diet for 14 d, at the end of which (day 0), 4 mink were sacrificed to determine baseline methylmercury (MeHg) concentrations. From day 0 to day 10, the remaining mink were fed a diet consisting of the base diet supplemented with 0.513 ± 0.013 µg Me199Hg/g and 0.163 ± 0.003 µg Me201Hg/g. From day 10 to day 60, mink were fed the base diet supplemented with 0.175 ± 0.024 µg Me201Hg/g. Animals were sacrificed periodically to determine accumulation of Me201Hg in blood and hair over the entire 60-d period and the elimination of Me199Hg over the last 50 d. Hair samples, collected from each mink and cut into 2.0-mm lengths, indicate that both isotopes of MeHg appeared in the hair closest to the skin at approximately day 10, with concentrations in the hair reaching steady state from day 39 onward. The elimination rate of Me199Hg from the blood was 0.05/d, and the ratio of MeHg in the hair to blood was 119. A large fraction of MeHg (22% to &gt;100%) was stored in the hair, suggesting that in fur-bearing mammals the hair is a major route of elimination of MeHg from the body.

Published: September 2014

ABSTRACTThermal reactions of empty fullerenes with disilirane (1) and digermirane (2) afforded the corresponding bis‐silylated and bis‐germylated derivatives. When a bicyclic fused silirane (3a) was heated in the presence of C70, two silylene adducts were obtained through thermal extrusion of silylenes. These results provide a complementary method to the photochemical addition of reactive silicon and germanium compounds, which have been long employed for derivatization of fullerenes. Electrochemical analyses revealed the redox properties of the silylated and germylated C70, indicating the electronic perturbation caused by silyl and germyl groups introduced on the fullerene cages. Theoretical calculations were also conducted for understanding of the electronic property of the fullerene derivatives.
The Mechanisms through Which Certain Variables Influence Customer Loyalty: The Mediating Roles of Perceived Value and Satisfaction
Authors: Petnji Yaya Luc Honore , Marimon Frederic , Casadesus Marti 
Published: September 2014

AbstractThis study surveyed 123 bank users who experienced problems with their banks’ online banking services, with the aim of understanding the mechanisms through which certain variables influence customer loyalty. Principally, the possible mediating roles of value and satisfaction on the relationships between recovery and loyalty and between ISO 9001 and loyalty were scrutinized. The dimensionalities of the scales were assessed using exploratory and confirmatory factor analysis. Thereafter, structural equation modeling and multiregression analyses were used to test the proposed model. The overall results showed that service recovery can be used to enhance customers’ satisfaction and perception of value and, therefore, customer loyalty. This study also confirmed the partial mediating roles of customers’ satisfaction and perception of value in the relationship between service recovery and loyalty. In contrast, ISO 9001 has no influence on perceived value, satisfaction, and loyalty; the mediating roles of both perceived value and satisfaction were not supported in the relationship between ISO 9001 and loyalty. In practice, even though ISO 9001 appeared to offer few extras to satisfy and retain customers, its use is still advisable because of the other potential benefits that it provides.
