Is What You Feel What They See? Prominent and Subtle Identity Signaling in Intergroup Interactions
Authors: Matherly Ted , Pocheptsova Ghosh Anastasiya 
Published: March 2017

AbstractIndividuals often signal group affiliations to others, and the display of such identity signals is frequently rather subtle. While prior work has focused on understanding an individual's choices of subtle versus prominent signals, in this work, we look at the downstream consequences of such choices. Specifically, we explore how the prominence of identity signals may affect one's behavior in intergroup interactions. Drawing from literature on processing fluency, we propose that the use of difficult to process (subtle) identity signals in intergroup interactions leads signalers to experience identity threat, lowering confidence in their identity and leading them to engage in behaviors to recover from this experience. Across three different identity domains (college affiliation, political affiliation, and brand loyalty), we show that when individuals use difficult to process identity signals, they derogate out‐group members in communication and behave less cooperatively in intergroup interactions. We find that these effects depend upon the observability of the signals by out‐group members and only occur for individuals who are highly identified with the in‐group. We also find that the effects are attenuated when behavior towards members of the out‐group is made public. Copyright © 2017 John Wiley & Sons, Ltd.

AbstractA strategy has been applied to chloramphenicol (CAP) detection with chemiluminescence immunoassays (CLIA) based on cheap functionalized Fe3O4@SiO2 magnetic nanoparticles (Fe–MNPs). The strategy that bovine serum albumin (BSA) was immobilized on cheap functionalized Fe–MNPs and that the CAP molecules were then immobilized on BSA, avoided the long process of dialysis for preparation of the BSA‐CAP conjugates. The samples were detected for both methods that utilized two different kinds of functionalized Fe–MNPs (amine‐functionalized Fe3O4@SiO2 and carboxylic acid‐functionalized Fe3O4@SiO2). The sensitivities and limits of detection (LODs) of the two methods were obtained and compared based on inhibition curves. The 50% inhibition concentrations (IC50) values of the two methods were about 0.024 ng ml−1 and 0.046 ng ml−1 respectively and LODs were approximately 0.0002 ng ml−1 and 0.001 ng ml−1 respectively. These methods were much more sensitive than that of any traditional enzyme‐linked immunosorbent assay (ELISA) previously reported. Therefore, such chemiluminescence methods could be easily adapted for small molecule detection in a variety of foods using Fe–MNPs.

AbstractIdentification of target genes of NF‐κB is critical for deeply understanding its biological functions. Here, we identified five novel NF‐κB target genes. Firstly, we found that 20 NF‐κB potential target genes (PTGs) identified by ChIP‐Seq and Genechip assay were enriched into the KEGG term of Pathways in cancer, 16 of them were enriched into the KEGG pathways of small cell lung cancer, chronic myeloid leukemia, basal cell carcinoma, pancreatic cancer, and colorectal cancer. Among these PTGs, there are many documented NF‐κB target genes. Therefore, NF‐κB may play important role in cancer progression by transcriptionally regulating these genes. Apart from the known target genes, we also found some novel PTGs including CYCS, MITF, FZD1, FZD8, and PIAS1. We subsequently demonstrated whether NF‐κB transcriptionally control the five PTGs. The ChIP‐Seq assay revealed that NF‐κB/p65 bound to these genes in TNFα‐treated HeLa. The bioinformatic analysis indicated that the NF‐κB binding regions (i.e., ChIP‐Seq peaks) contained κB sites and NF‐κB/RelA DNA‐binding motif. The ChIP‐qPCR assay also confirmed that NF‐κB bound to these regions in both TNFα‐treated HeLa and HepG2 cells. The reporter construct showed that NF‐κB could regulate luciferase expression via its binding region. Finally, qPCR and Western blot assay demonstrated that NF‐κB indeed regulated the expression of these genes in the TNFα‐treated HeLa and HepG2 cells. In a word, CYCS, MITF, FZD1, FZD8, and PIAS1 were identified as bona fide NF‐κB target genes. These findings provide more insights into the role of NF‐κB in cancers.
The association between type of out‐of‐home mental health treatment and juvenile justice recidivism for youth with trauma exposure

Published: March 2017

AbstractBackgroundHigh rates of mental health disorders and exposure to trauma among the juvenile justice population highlight the importance of understanding whether and how mental health services can help prevent further justice system involvement as well as provide treatment.AimsWe had two principal questions: Is out‐of‐home mental health treatment after arrest associated with reduced recidivism among young people who have been exposed to trauma? Are particular types of out‐of‐home treatment associated with better outcomes? We hypothesised that type of residential setting would affect outcomes among those with histories of serious trauma.MethodsPrimary data sources included Florida Juvenile Justice, Child Welfare and Medicaid data from July 2002 through June 2008. We identified all Florida Juvenile Justice cases with a record of ‘severe emotional disturbance’. Two groups were identified – one for whom an arrest was followed within 90 days by out‐of‐home placement for mental health treatment and the other for whom there was some other out‐of‐home placement. Generalised estimating equations (GEE) were used to calculate associations with likelihood of re‐arrest during a 12 month at risk period.ResultsYoung people who had experienced severe trauma and were sent to out‐of‐home treatment settings after conviction for a criminal offence had lower recidivism rates when receiving treatment in foster care than other out‐of‐home placements, while those with less severe or no trauma histories had lower recidivism rates with any out‐of‐home placement.Conclusions and implications for practiceWe believe that this is the first study to have considered how trauma histories may mediate outcomes for young people in out‐of‐home placements after arrest or conviction for a criminal offence. Findings suggest that case managers and clinicians should consider the trauma histories when making decisions about the appropriate treatment setting in these circumstances.

A Mixed N‐Heterocyclic Carbene/2,2′‐Bipyridine‐Supported Robust Ruthenium(II) Oxidation Precatalyst for Benzylic C−H Oxidation
Authors: Gupta Suraj K. , Choudhury Joyanta 
Published: March 2017

AbstractCatalytic oxidation of hydrocarbons to the oxygenated derivatives has been an important research area for a long time and the search for well‐defined, tunable, efficient, selective, and robust oxidation (pre)catalysts is still on. To further develop the applicability of N‐heterocyclic carbene (NHC) ligands, herein we report a mixed NHC/bipyridine‐supported ruthenium(II) oxidation precatalyst, [(Npy^CNHC)RuII(Npy^Npy)(CH3CN)2](PF6)(CF3SO3), 1 (Npy^CNHC=a bidentate ′2‐pyridyl‐NHC′ neutral ligand, Npy^Npy=2,2′‐bipyridine) consisting of two cis‐disposed loosely bound solvent ligands, which was successfully utilized for catalytic benzylic C−H oxidation of a variety of aromatic hydrocarbons to the corresponding ketones in 65–90 % yields with the mild sacrificial oxidant NaIO4. The ligand backbone was found to be robust under oxidizing conditions. The presence of these ligands around the ruthenium center was crucial for the system, as the known RuCl3/NaIO4 and [Ru(para‐cymene)Cl2]2/NaIO4 combinations were proved to be completely ineffective precatalysts under similar conditions. The scope and mechanistic aspects of this precatalyst were also evaluated.

Published: March 2017

AbstractVarious supported metal catalysts are screened for hydrogenation of lauric acid and 2‐octanone as model reactions for the transformation of biomass‐derived oxygenates to liquid alkanes (biofuels) in a batch reactor under solvent‐free conditions. Among the catalysts tested, Pt and MoOx co‐loaded on TiO2 (Pt–MoOx/TiO2) shows the highest yields of n‐alkanes for both of the reactions. Pt–MoOx/TiO2 selectively catalyzes the hydrodeoxygenation of various fatty acids and triglycerides to n‐alkanes without C−C bond cleavage under 50 bar H2 and shows higher turnover numbers than the catalysts in the literature. Pt–MoOx/TiO2 is effective also for the hydrodeoxygenation of various ketones to the corresponding alkanes. In situ IR study of the reaction of adsorbed acetone under H2 suggests that the high activity of Pt–MoOx/TiO2 is attributed to the cooperation between Pt and Lewis acid sites of the MoOx/TiO2 support.

Published: March 2017

AbstractThe nature of the molecular assemblies formed in the crystalline state by cobalt(II) terpyridine (terpy) complexes incorporating appended adenine (A) or thymine (T) bases was found to be controlled by which bases are present. Single‐crystals of the cobalt(II) complexes [Co(A‐C6‐terpy)2](BF4)2 (1) and [Co(T‐C6‐terpy)2](BF4)2 (2) have needle and block habits, respectively. Subsequent mixing of 1 and 2 in MeOH resulted in isolation of [Co(A‐C6‐terpy)1.5(T‐C6‐terpy)0.5](BF4)2 (3) as plate‐like crystals. A 3D network structure is present in 1 that incorporates 1D chains, whereas 2 adopts a 2D stacked structure constructed from ladder‐type assemblies. For 3, “dimer‐rings” consisting of [Co(A‐C6‐terpy)2]2+ and [Co(A‐C6‐terpy)(T‐C6‐terpy)]2+ units are generated by means of base‐pairing between A and T. Notably, 3 displays the first crystal structure of a heteroleptic cobalt(II) complex of [Co(A‐C6‐terpy)(T‐C6‐terpy)](BF4)2. These assembly differences involving the terpyridine cobalt(II) complex units in 1–3 affect the cooperativities influencing their spin crossover (SCO) behavior. The influence of the terminal nucleobases on the resulting assembly has been probed by investigating the co‐crystallization of [Co(terpy)2](BF4)2 (4) with [Co(C6‐terpy)2](BF4)2 (5) and 1 with 5.
Information order effects in clinical psychological diagnoses
Authors: Cwik Jan Christopher , Margraf Jürgen 
Published: March 2017

Despite the wide application and long history of diagnostic systems, several sources of diagnostic errors remain in the criterion‐based diagnosing of mental disorders. The aim of this study was to investigate whether the presentational order of diagnosis‐relevant information and pretreatment reports predict diagnostic errors. One hundred twenty psychotherapists participated in the present online study. The study employed a 2 (symptom presentation: core symptoms at vignette's beginning vs. core symptoms at the end of the case vignette) × 2 (pretreatment report: receiving a pretreatment report with an incongruent diagnosis to the case vignette vs. receiving no pretreatment report) between‐subjects experimental design, with random assignment. Participants were asked to make diagnoses after reading three case vignettes describing patients with different disorder constellations. Additionally, participants rated their confidence in the diagnoses and their estimation of the severity of each diagnosed condition. Results indicated that order of symptom descriptions predicted the correctness of diagnostic decisions, with a recency effect causing more fully correct diagnostic decisions in cases where diagnostic information was presented last. Receiving incongruent pretreatment reports was predictive for diagnostic errors. In conclusion, the results of this study indicate that diagnoses of mental disorders can depend on the way symptoms are presented or reported.Key Practitioner Message:

Therapists' diagnostic decisions are not influenced by pretreatment reports.
Diagnostic decisions are affected by information order effects.
Diagnostic accuracy of psychotherapists is debatable.
High rate of misdiagnoses in case vignette with comorbid disorders.
Integrating CdSe Quantum Dots with a [FeFe]‐Hydrogenase Mimic into a Photocathode for Hydrogen Evolution at a Low Bias Voltage

Published: March 2017

AbstractA simple [FeFe]‐hydrogenase mimic, Fe2S2(CO)6, was integrated with CdSe quantum dots to form a sensitized electrode on a p‐NiO layer, which can start to catalyze proton reduction at a bias voltage as positive as ≈0.3 V (vs. NHE) in neutral water. The result provides a promising way to overcome the much more negative onset bias of [FeFe]‐hydrogenase mimics for H2 evolution under mild conditions.
Flight performance in the altricial zebra finch: Developmental effects and reproductive consequences

Published: March 2017

AbstractThe environmental conditions animals experience during development can have sustained effects on morphology, physiology, and behavior. Exposure to elevated levels of stress hormones (glucocorticoids, GCs) during development is one such condition that can have long‐term effects on animal phenotype. Many of the phenotypic effects of GC exposure during development (developmental stress) appear negative. However, there is increasing evidence that developmental stress can induce adaptive phenotypic changes. This hypothesis can be tested by examining the effect of developmental stress on fitness‐related traits. In birds, flight performance is an ideal metric to assess the fitness consequences of developmental stress. As fledglings, mastering takeoff is crucial to avoid bodily damage and escape predation. As adults, takeoff can contribute to mating and foraging success as well as escape and, thus, can affect both reproductive success and survival. We examined the effects of developmental stress on flight performance across life‐history stages in zebra finches (Taeniopygia guttata). Specifically, we examined the effects of oral administration of corticosterone (CORT, the dominant avian glucocorticoid) during development on ground‐reaction forces and velocity during takeoff. Additionally, we tested for associations between flight performance and reproductive success in adult male zebra finches. Developmental stress had no effect on flight performance at all ages. In contrast, brood size (an unmanipulated variable) had sustained, negative effects on takeoff performance across life‐history stages with birds from small broods performing better than birds from large broods. Flight performance at 100 days posthatching predicted future reproductive success in males; the best fliers had significantly higher reproductive success. Our results demonstrate that some environmental factors experienced during development (e.g. clutch size) have stronger, more sustained effects than others (e.g. GC exposure). Additionally, our data provide the first link between flight performance and a direct measure of reproductive success.
Consumptive and nonconsumptive effect ratios depend on interaction between plant quality and hunting behavior of omnivorous predators
Authors: Stephan Jörg G. , Stenberg Johan A. , Björkman Christer 
Published: March 2017

SummaryPredators not only consume prey but exert nonconsumptive effects in form of scaring, consequently disturbing feeding or reproduction. However, how alternative food sources and hunting mode interactively affect consumptive and nonconsumptive effects with implications for prey fitness have not been addressed, impending functional understanding of such tritrophic interactions. With a herbivorous beetle, two omnivorous predatory bugs (plant sap as alternative food, contrasting hunting modes), and four willow genotypes (contrasting suitability for beetle/omnivore), we investigated direct and indirect effects of plant quality on the beetles key reproductive traits (oviposition rate, clutch size). Using combinations of either or both omnivores on different plant genotypes, we calculated the contribution of consumptive (eggs predated) and nonconsumptive (fewer eggs laid) effect on beetle fitness, including a prey density‐independent measure (c:nc ratio). We found that larger clutches increase egg survival in presence of the omnivore not immediately consuming all eggs. However, rather than lowering mean, the beetles generally responded with a frequency shift toward smaller clutches. However, female beetles decreased mean and changed clutch size frequency with decreasing plant quality, therefore reducing intraspecific exploitative competition among larvae. More importantly, variation in host plant quality (to omnivore) led to nonconsumptive effects between one‐third and twice as strong as the consumptive effects. Increased egg consumption on plants less suitable to the omnivore may therefore be accompanied by less searching and disturbing the beetle, representing a “cost” to the indirect plant defense in the form of a lower nonconsumptive effect. Many predators are omnivores and altering c:nc ratios (with egg retention as the most direct link to prey fitness) via plant quality and hunting behavior should be fundamental to advance ecological theory and applications. Furthermore, exploring modulation of fitness traits by bottom‐up and top‐down effects will help to explain how and why species aggregate.

Authors: Traviss‐Turner Gemma D. , West Robert M. , Hill Andrew J. 
Published: March 2017

AbstractBackgroundEvidence‐based self‐help is a recommended first stage of treatment for mild–moderate eating disorders. The provision of guidance enhances outcome. The literature evaluating exclusively ‘guided’ self‐help (GSH) has not been systematically reviewed.MethodsThe aim was to establish the effectiveness of GSH for reducing global eating disorder psychopathology and abstinence from binge eating, compared with controls. Results were pooled using random effects meta‐analysis and heterogeneity explored using metaregression.ResultsThirty randomised controlled trials met the inclusion criteria. Results showed an overall effect of GSH on global eating disorder psychopathology (−0.46) and binge abstinence (−0.20). There was strong evidence for an association between diagnosis of binge eating disorder and binge abstinence.DiscussionCurrent interventions need to be adapted to address features other than binge eating. Further research is required to help us understand the effectiveness of GSH in children and young people, invariably high dropout rates and how technology can enhance interventions.

Observations of the reduction in surface artifact frequency as a result of multimodal plowing
Authors: O'Neal Michael A. , Lowery Darrin 
Published: March 2017

AbstractThe frequency and distribution of plowzone artifacts are compared with the timing and duration of two plow modes at two study locales on the Delmarva Peninsula, United States. Our results indicate that historic moldboard plowing created a maximum plowzone of ca. 0.30 m, in which artifacts were retained over time. Later, soil‐conservative chisel plowing mixed the top ca. 0.15 m of soil, creating a shallow, minimum plowzone. With time and repeated plowing, our data suggest that the number of artifacts at the surface diminished via a combination of vertical mixing and/or degradation, physical and chemical weathering, and avocational collecting. When moldboard plowing is reapplied to fields after decades of chisel plowing, the historic maximum plowzone is inverted and the surface is re‐saturated with artifacts. This inverted maximum plowzone retains an inherent pattern of artifact transport from moldboard plowing, which supports other studies that have measured such displacements over time. Our results suggest that the frequency of artifacts observed at the surface of agricultural fields, or lack thereof, is a likely outcome of natural and mechanical processes, and removal within the minimum plowzone. This inevitable depletion of artifacts may have negative repercussions for many research designs that systematically sample the plowzone.

ABSTRACTRecently the use of dissimilar metals in spine instrumentation has increased, especially in the case of adult deformities, where rods made from Cobalt Chrome alloys (CoCr) are used with Titanium (Ti) screws. The use of dissimilar metals increases the risk of galvanic corrosion and patients have required revision spine surgery due to severe metallosis that may have been caused by corrosion. We aimed to assess the presence of corrosion in spine implant retrievals from constructs with two types of material combinations: similar (Ti/Ti) and dissimilar (CoCr/Ti). First, we devised a grading score for corrosion of the rod‐fixture junctions. Then, we applied this score to a collection of retrieved spine implants. Our proposed corrosion grading score was proven reliable (kappa > 0.7). We found no significant difference in the scores between 4 CoCr and 11 Ti rods (p = 0.0642). There was no indication that time of implantation had an effect on the corrosion score (p = 0.9361). We recommend surgeons avoid using implants designs with dissimilar metals to reduce the risk of corrosion whilst a larger scale study of retrieved spine implants is conducted. Future studies can now use our scoring system for spine implant corrosion. © 2017 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 106B: 632–638, 2018.

AbstractIn the development of new metallic biomaterials, the Ti–15Mo alloy has great prominence because of its excellent corrosion resistance and good combination of mechanical properties. In this study, the element niobium was added to the Ti–15Mo alloy, forming the Ti–15Mo–Nb system for the purpose of improving their properties and promoting its application as a biomaterial. These alloys are very promising to use as biomedical implants, because they integrate a new class of titanium alloys without the presence of aluminum and vanadium, which may cause cytotoxic effects. The alloys were produced by arc‐melting and characterized by density, X‐ray diffraction, scanning electron microscopy, microhardness, elastic modulus, corrosion, and cytotoxicity assays. The developed alloys have β phase predominance (with bcc crystalline structure). The addition of niobium decreases the microhardness and elastic modulus, with values around 80 GPa, which is well below that of the metallic alloys used commercially for this type of application. Very low passive current densities were found for all alloys studied showing that the passive film on these alloys is highly protective. In vitro cytotoxicity tests revealed that the introduction of niobium did not cause cytotoxic effects in the studied alloys. © 2017 Wiley Periodicals, Inc.
