I love the product but will you? The role of interpersonal attachment styles in social projection
Authors: David Meredith E. 
Published: February 2018

AbstractIndividuals often have a need to predict the preferences of others (e.g., offering a recommendation, gift giving). In doing so, it is not uncommon that individuals project their attitudes and preferences onto others. Extant consumer research literature related to social projection focuses largely on particular situational variables that influence social projection. The current research adds to a smaller body of consumer research which focuses on specific characteristics of consumers’ selves that may drive an individual's tendency to project his/her attitudes onto others. Specifically, the present paper explores an individual‐level moderator of social projection, namely, interpersonal attachment style. Across five studies, interpersonal attachment style, and attachment anxiety, specifically, is shown to influence social projection. In addition, the mechanism underlying this relationship is demonstrated. The results show that high (vs. low) anxious attachment individuals tend to naturally consider more counter‐valence attributes of a product, that is., liked attributes of a disliked product and disliked attributes of a liked product, and this availability of counter‐valence attributes lowers social projection. Important theoretical and practical implications are discussed.

AbstractChemoautotrophic bacteria belonging to the genus Sulfurimonas in the class Campylobacteria are widespread in many marine environments characterized by redox interfaces, yet little is known about their physiological adaptations to different environmental conditions. Here, we used liquid chromatography coupled with tandem mass spectrometry (LC‐MS/MS) in a targeted metabolomics approach to study the adaptations of Sulfurimonas denitrificans to varying salt concentrations that are found in its natural habitat of tidal mudflats. Proline was identified as one of the most abundant internal metabolites and its concentration showed a strong positive correlation with ionic strength, suggesting that it acts as an important osmolyte in S. denitrificans. 2,3‐dihydroxypropane‐1‐sulfonate was also positively correlated with ionic strength, indicating it might play a previously unrecognized role in osmoregulation. Furthermore, the detection of metabolites from the reductive tricarboxylic acid cycle at high internal concentrations reinforces the importance of this pathway for carbon fixation in Campylobacteria and as a hub for biosynthesis. As the first report of metabolomic data for an campylobacterial chemolithoautotroph, this study provides data that will be useful to understand the adaptations of Campylobacteria to their natural habitat at redox interfaces.

PurposeA 16‐channel multi‐coil shimming setup was developed to mitigate severe B0 field perturbations at ultrahigh field and improve data quality for human brain imaging and spectroscopy.MethodsThe shimming setup consisted of 16 circular B0 coils that were positioned symmetrically on a cylinder with a diameter of 370 mm. The latter was large enough to house a shielded 18/32‐channel RF transceiver array. The shim performance was assessed via simulations and phantom as well as in vivo measurements at 9.4 T. The global and dynamic shimming performance of the multi‐coil setup was compared with the built‐in scanner shim system for EPI and single voxel spectroscopy.ResultsThe presence of the multi‐coil shim did not influence the performance of the RF coil. The performance of the proposed setup was similar to a full third‐order spherical harmonic shim system in the case of global static and dynamic slice‐wise shimming. Dynamic slice‐wise shimming with the multi‐coil setup outperformed global static shimming with the scanner's second‐order spherical‐harmonic shim. The multi‐coil setup allowed mitigating geometric distortions for EPI. The combination of the multi‐coil shim setup with the zeroth and first‐order shim of the scanner further reduced the standard deviation of the B0 field in the brain by 12% compared with the case in which multi‐coil was used exclusively.ConclusionThe combination of a multi‐coil setup and the linear shim channels of the scanner provides a straightforward solution for implementing dynamic slice‐wise shimming without requiring an additional pre‐emphasis setup.
Non‐Contact Measurement Brings Decisive Optimization

Published: February 2018

AbstractThe intervals at which production efficiency in optics need to be streamlined are getting shorter and shorter, due to the fast pace at which optical device technology is moving forward. Companies need to know their breaking point. Organizational stress testing becomes essential for economic survival in the global business arena. A small but important aspect of production improvement can be achieved by opting for non‐contact measurement of lens center thicknesses, especially when dealing with microlenses.
Growing up in Australia: paradox of overweight/obesity in children of immigrants from low‐and‐middle ‐income countries

Published: February 2018

SummaryObjectiveChildren of immigrants from low‐and‐middle‐income countries show excess overweight/obesity risk relative to host populations, possibly due to socioeconomic disadvantage. The present study was conducted to estimate overweight/obesity prevalence and its association with the family socioeconomic‐position in 2–11‐year‐old Australian‐born children of immigrants and Australian‐mothers.MethodsA cross‐sectional analysis of 10‐year data from the Longitudinal Study of Australian Children was undertaken. Overweight/obesity was defined according to the International Obesity Taskforce, age‐and sex‐specific BMI cut‐off‐points.ResultsApproximately 24% children aged 2–3 years (22% sons, and 25% daughters), were overweight/obese with no significant difference between children of immigrants and Australian‐mothers. Overweight/obesity prevalence consistently increased with age for sons of mothers from low‐and‐middle‐income countries but not daughters. Adjusting for the family socioeconomic‐position did not explain excess overweight/obesity in children of mothers from low‐and‐middle‐income countries. The odds of overweight/obesity in sons were significantly higher at 8–9 years (OR 1.5; p = 0.03) and 10–11 years (OR 1.5; p = 0.03) and in daughters at 4–5 years (OR 1.7; p = 0.002) when the mothers were from low‐and‐middle‐income countries.ConclusionExcess weight in children of immigrants is not due to socioeconomic disadvantage alone. Other social processes and interactions between immigrants and host cultures may be involved.
Novel hydrogels based on a high‐molar‐mass water‐soluble dimethacrylate monomer
Authors: Asmussen Silvana V , Gomez Maria L , Vallo Claudia I 
Published: February 2018

AbstractThis report describes the preparation and swelling behaviour of novel hydrogels based on a water‐soluble dimethacrylate monomer (EBisEMA), which is characterized by a relatively high molar mass (Mn ∼ 1700 g mol−1) and contains a high proportion of aliphatic ether bonds in its structure. This feature results in moderately crosslinked and flexible polymer networks. Significant differences were observed in degree of swelling, depending on the synthesis method employed to obtain the hydrogels. The equilibrium water sorption of EBisEMA photopolymerized in bulk was 68 wt% while that of EBisEMA photopolymerized in aqueous solution (0.5 g mL−1) was 104 wt%. Thiol–methacrylate hydrogels were prepared by visible light photopolymerization of EBisEMA with a tetrafunctional thiol (PETMP) at various EBisEMA‐to‐PETMP molar ratios. These hydrogels contained unreacted thiol groups because of a faster homopolymerization reaction of EBisEMA. Hydrogels were also prepared in bulk by propylamine‐catalysed Michael addition reaction. No significant differences in swelling were observed between EBisEMA homopolymer and photocured EBisEMA–PETMP copolymer. Conversely, a marked increase in water uptake (110 wt%) was observed in the EBisEMA–PETMP hydrogels prepared by the Michael addition reaction catalysed by propylamine. These trends are explained in terms of a balance between the mass fraction of hydrophilic groups and the crosslinking density of the network. EBisEMA–PETMP hydrogels formulated with thiol in excess showed a noticeable tendency to adhere to diverse substrates, including paper, metals, glass and skin. This feature makes them especially attractive in applications for which adhesion is particularly critical such as dermatological patches. © 2018 Society of Chemical Industry
Preparation of poly(butylene succinate)‐poly[2‐(dimethylamino)ethyl methacrylate] copolymers and their applications as carriers for drug delivery

Published: February 2018

AbstractCopolymers of poly[2‐(dimethylamino)ethyl methacrylate]–poly(butylene succinate)–poly[2‐(dimethylamino)ethyl methacrylate] (PDMAEMA–PBS–PDMAEMA, PDBD) were synthesized through a chain‐extension reaction. The thermal properties characterized using differential scanning calorimetry showed that the introduction of PDMAEMA chains slightly decreased the melting temperature of PBS. The water contact angle of PDBD copolymer films with media of various pH decreased with a decrease of pH. This should be ascribed to the conformational transition of PDMAEMA blocks from a compact coil to an expanding shape in accordance with the variation of the pH of the surroundings. The results of dynamic light scattering and scanning electron microscopy revealed that PDBD copolymers could form spherical micelles with small particle size and narrow particle size distribution. Furthermore, drug loading (loading content, ca 10%; encapsulation efficiency, ca 60%) and release experiments were conducted using doxorubicin as a hydrophobic model drug. The results of release experiments of copolymer nanomicelles showed that these micelles had pH‐responsive properties. © 2018 Society of Chemical Industry
A simple distillation method to extract bromine from natural water and salt samples for isotope analysis by multi‐collector inductively coupled plasma mass spectrometry
Authors: Eggenkamp H.G.M. , Louvat P. 
Published: February 2018

RationaleIn natural samples bromine is present in trace amounts, and measurement of stable Br isotopes necessitates its separation from the matrix. Most methods described previously need large samples or samples with high Br/Cl ratios. The use of metals as reagents, proposed in previous Br distillation methods, must be avoided for multi‐collector inductively coupled plasma mass spectrometry (MC‐ICP‐MS) analyses, because of risk of cross‐contamination, since the instrument is also used to measure stable isotopes of metals.MethodsDedicated to water and evaporite samples with low Br/Cl ratios, the proposed method is a simple distillation that separates bromide from chloride for isotopic analyses by MC‐ICP‐MS. It is based on the difference in oxidation potential between chloride and bromide in the presence of nitric acid. The sample is mixed with dilute (1:5) nitric acid in a distillation flask and heated over a candle flame for 10 min. The distillate (bromine) is trapped in an ammonia solution and reduced to bromide. Chloride is only distilled to a very small extent. The obtained solution can be measured directly by MC‐ICP‐MS for stable Br isotopes.ResultsThe method was tested for a variety of volumes, ammonia concentrations, pH values and distillation times and compared with the classic ion‐exchange chromatography method. The method more efficiently separates Br from Cl, so that samples with lower Br/Cl ratios can be analysed, with Br isotope data in agreement with those obtained by previous methods.ConclusionsUnlike other Br extraction methods based on oxidation, the distillation method presented here does not use any metallic ion for redox reactions that could contaminate the mass spectrometer. It is efficient in separating Br from samples with low Br/Cl ratios. The method ensures reproducible recovery yields and a long‐term reproducibility of ±0.11‰ (1 standard deviation). The distillation method was successfully applied to samples with low Br/Cl ratios and low Br amounts (down to 20 μg).

Published: February 2018

SummaryThis paper studies the stability of a class of nonlinear fractional‐order (FO) systems under input control saturation. Based on the Gronwall‐Bellman lemma and the sector‐bounded condition, sufficient conditions are provided to stabilize such systems by means of a state‐feedback controller. The performance of the proposed controller is tested with 2 FO chaotic systems, namely, the FO brushless direct‐current motor and the Chen systems. The results illustrate the good performance of the new controller under saturation effects.

AbstractSynthesis, characterization and biological activities of a silver(I) complex with cycloserine (AgCIC) are presented. Elemental, thermal and mass spectrometric analyses permitted proposing the minimal formula AgC3H5N2O2. The structure of the AgCIC complex was solved by powder X‐ray diffraction (XRD) studies. Coordination of the ligand to silver was shown to occur by the nitrogen atom of the heterocyclic ring and by the nitrogen and oxygen atoms of the amino and carbonyl groups, leading to a polymeric arrangement. Infrared (IR) and nuclear magnetic resonance (NMR) spectroscopic analyses confirmed the coordination sites. Antibacterial assays revealed the activity of the AgCIC complex against Mycobacterium tuberculosis, with minimal inhibitory concentration (MIC90) of 79.1 μmol⋅L−1, and against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa bacterial strains. Antiproliferative assays over a panel of tumoral and non‐tumoral cells showed that the AgCIC complex is more active and selective than doxorubicin against breast and leukemia cancer cells, considering the total growth inhibition (TGI) values. The interaction of the complex with biomolecules and its mutagenicity were also investigated.

AbstractMetal silicides are unconventional heterogeneous catalysts. Herein, cobalt silicide nanoparticles (NPs) embedded in N‐doped carbon (CoxSi@C−N) catalysts have been synthesized by microwave‐assisted silicification of metal‐organic framework‐templated Co@C−N NPs successfully. The phase transitions of cobalt silicide can be controlled by the numbers of microwave cycles. The synthesized CoxSi@C−N‐2 catalyst possesses an ordered and uniform porous structure, high cobalt content (8.85 at.%), high specific surface area (236 m2 g−1), and highly dispersed and small NPs (10‐15 nm). The cobalt silicide catalyst is firstly used for selective hydrogenation of cinnamaldehyde. Owing to the strong modification of geometric structure and electronic properties by silicon, the particle size effect, and the Mott‐Schottky effect at the metal‐support interface, the as‐synthesized CoxSi@C−N exhibits catalytic performance that is superior to its counterpart Co@C−N. In addition, this silicide catalyst sustains the robust stability in hydrogenation of cinnamaldehyde.

AbstractDue to their unique optical properties, diamonds are the most valued gemstones. However, beyond the sparkle, diamonds have a number of unique properties. Their extreme hardness gives them outstanding performance as abrasives and cutting tools. Similar to many materials, their nanometer‐sized form has yet other unique properties. Nanodiamonds are very inert but still can be functionalized on the surface. Additionally, they can be made in very small sizes and a narrow size distribution. Nanodiamonds can also host very stable fluorescent defects. Since they are protected in the crystal lattice, they never bleach. These defects can also be utilized for nanoscale sensing since they change their optical properties, for example, based on temperature or magnetic fields in their surroundings. In this Review, in vivo applications are focused upon. To this end, how different diamond materials are made and how this affects their properties are discussed first. Next, in vivo biocompatibility studies are reviewed. Finally, the reader is introduced to in vivo applications of diamonds. These include drug delivery, aiding radiology, labeling, and use in cosmetics. The field is critically reviewed and a perspective on future developments is provided.

Published: February 2018

AbstractGars (family Lepisosteidae) play important roles as apex predators in freshwater ecosystems, helping to balance fish populations. Several gar species are exploited as food and game fish, and some species are classified as vulnerable due to habitat loss. New molecular techniques to detect, monitor, and identify environmental DNA (eDNA) from gars might help inform management and conservation efforts for these interesting fish. The goal of this project was to develop and test PCR primers for gars, using specimens of all seven gar species, which are on exhibit at the Belle Isle Aquarium in Detroit, Michigan. Focusing on the mitochondrial gene for cytochrome oxidase I, we first designed primers to amplify DNA from all species of gars (“universal gar primers”) and confirmed their specificity in silico. These primers amplified DNA from all seven species, and species identities were confirmed by sequencing the PCR products. Only one of the three ostensibly Shortnose Gar Lepisosteus platostomus specimens sampled exhibited a Shortnose Gar matriline; two other specimens may be Longnose Gar L. osseus × Shortnose Gar hybrids. Genus‐targeted primers were developed that amplified all Atractosteus species and two of four Lepisosteus species. Species‐specific primers were developed for Longnose Gar, Shortnose Gar, and Tropical Gar Atractosteus tropicus. A primer set that targeted Alligator Gar A. spatula also amplified DNA from Cuban Gar A. tristocheus, but not other species. While the universal gar primers followed by sequencing confirmed the identities of all seven gar species at the Belle Isle Aquarium, PCR with the species‐specific primers enabled direct detection of the presence of DNA from the targeted species in the water in which those species had been maintained. Designing these primers is the first step in developing eDNA markers for gars, which in turn could inform the conservation and management of gar populations.

AbstractFish in the family Lepisosteidae (hereafter, gars) have unique ganoid scales that pose inherent challenges to implanting electronic tags in their coeloms for telemetry studies. In this paper we outline a unique approach to conducting laparotomic surgery in gars, with a focus on the Longnose Gar Lepisosteus osseus. An electric rotary tool with a circular cutting blade was used to cut through the scales, and the same tool, with a drill bit, was used to create holes through which to run the suture material. The final incision into the body cavity was made with a scalpel, and the incision was expanded using surgical scissors. Using a passive acoustic telemetry array, the survival of 12 of 15 tagged Longnose Gars was confirmed over a 123‐d period based on their detection at receivers outside of their areas of capture and release. Two individuals were recaptured 17–19 weeks postsurgery and showed complete healing of the wounds with limited evidence of scarring. This approach will allow for the long‐term tagging and tracking of gars to help elucidate their ecology.
