The Impact of Corporate Social Responsibility on Consumer Preference: A Structural Equation Analysis
Authors: Boccia Flavio , Sarnacchiaro Pasquale 
Published: August 2017

AbstractNowadays, environmental and social problems are very important for modern consumers and firms, which cannot operate only in accordance with the logic of profit. In this paper, by administering a questionnaire to consumers, we have tried to assess the impact of the solidarity of responsible initiatives on consumer preferences: the conclusions are also a matter for thought for further discussion. The investigation was conducted through a sample size survey. The analysis was carried out considering a representative sample of more than 300 families, selected on a functional relation to the objectives of the work in one of the most important and representative Italian cities. This study has two main aims: to investigate consumer preferences regarding responsible initiatives of a company; and to develop and validate a structural equation model, in order to formalize the origins of behaviours regarding consumer preferences towards responsible initiatives and detect the drivers of their purchase.

Published: August 2017

AbstractThe efficiency of the stoichiometric non‐covalent imprinting of the imide 2,3,5‐tri‐O‐acetyluridine (TAU) with 2,6‐bis(acrylamido)pyridine (BAAPy) as functional monomer due to their strong donor‐acceptor‐donor/acceptor‐donor‐acceptor (DAD/ADA) hydrogen bond array interaction has been evaluated by bulk imprinting. This study is the first to investigate the imprinting and template rebinding efficiencies of the TAU/BAAPy molecularly imprinted polymeric (MIP) system prepared by precipitation polymerisation. We found that the stoichiometric 1:1 T:FM ratio has not been maintained in precipitation polymerisation and an optimal TAU:BAAPy ratio of 1:2.5 was obtained in acetonitrile without agitation affording an affinity constant (1.7 × 104 M−1) and a binding capacity (3.69 μmol/g) higher than its bulk counterpart. Molecular modelling, NMR studies, and selectivity assays against analogues uridine and 2,3,5‐tri‐O‐acetyl cytidine (TAC) indicate that, aside from the DAD/ADA hydrogen bond interaction, BAAPy also interacts with the acetyl groups of TAU. Template incorporation and rebinding in precipitation MIPs are favoured by a moderate initiator concentration, ie, initiator:total monomer (I:TM) ratio of 1:131, while low I:TM ratio (ie, 1:200) drastically reduced template incorporation and binding capacity. Vigorous agitation by stirring showed higher template incorporation but significantly lower template rebinding compared to that prepared without agitation. While the imprinting efficiencies for the best performing bulk and precipitation TAU MIPs generated in this study were moderate, 41% and 60%, respectively, their rebinding capacities were only between 3 and 4% of the incorporated template. We also present quantitative nuclear magnetic resonance spectroscopy as an efficient method for MIP characterisation.

ABSTRACTThis Level II study assessed clinically relevant outcomes for repair of large, retracted infraspinatus tendons (ISTs) using a demineralized bone matrix (DBM) sponge (FlexiGraft) hydrated in platelet‐rich plasma (PRP) versus direct repair in a validated canine model. Adult research dogs (n = 10) were used. The IST was transected in each shoulder (n = 20) and randomized to direct repair or repair with DBM‐PRP interposition at 4 weeks posttransection. At 12 weeks postrepair, dogs were sacrificed, and the repair evaluated by magnetic resonance imaging (MRI), histology, and biomechanical testing. MRI and histology scores were significantly (p < 0.05) better in the DBM‐PRP shoulders. Biomechanical testing revealed significantly improved strength of the DBM‐PRP repairs at 5 and 10 mm of displacement, as well as for ultimate failure load. In this canine model of retracted IST repair, DBM‐PRP sponge hydrated in PRP was considered safe and effective. In addition, use of DBM‐PRP was associated with improved MRI and histologic appearance, and improved strength compared to direct repair. Clinical significance: Based on reported failure rates for repair of large, retracted rotator cuff tears, improving tendon‐to‐bone healing is critical. Use of DBM combined with PRP shows potential for addressing this critical clinical need. © 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 36:906–912, 2018.
Resilience by diversity: Large intraspecific differences in climate change responses of an Arctic diatom
Authors: Wolf Klara K. E. , Hoppe Clara J. M. , Rost Björn 
Published: August 2017

AbstractThe potential for adaptation of phytoplankton to future climate is often extrapolated based on single strain responses of a representative species, ignoring variability within and between species. The aim of this study was to approximate the range of strain‐specific reaction patterns within an Arctic diatom population, which selection can act upon. In a laboratory experiment, we first incubated natural communities from an Arctic fjord under present and future conditions. In a second step, single strains of the diatom Thalassiosira hyalina were isolated from these selection environments and exposed to a matrix of temperature (3°C and 6°C) and pCO2 levels (180 μatm, 370 μatm, 1000 μatm, 1400 μatm) to establish reaction norms for growth, production rates, and elemental quotas. The results revealed interactive effects of temperature and pCO2 as well as wide tolerance ranges. Between strains, however, sensitivities and optima differed greatly. These strain‐specific responses corresponded well with their respective selection environments of the previous community incubation. We therefore hypothesize that intraspecific variability and the selection between coexisting strains may pose an underestimated source of species' plasticity. Thus, adaptation of phytoplankton assemblages may also occur by selection within rather than only between species, and species‐wide inferences from single strain experiments should be treated with caution.
Synthesis of π‐Conjugated Polymer Thin Films by Electropolymerization of Benzodithiophene Derivatives
Authors: Wakana Sho , Nishiyama Hiroki , Inagi Shinsuke , Tomita Ikuyoshi 
Published: August 2017

Abstractπ‐conjugated polymer thin films are successfully prepared by the electropolymerization of 4,5‐diaryl benzodithiophenes, which are readily obtained by the three‐component coupling reactions of aryl iodides, 1,2‐di(thiophen‐2‐yl)ethyne, and phenylboronic acid, followed by the photochemical annulation. The resulting polymer films exhibit π‐conjugated properties as convinced from their UV–vis absorption spectra and cyclic voltammetric analyses. The electronic properties such as highest occupied molecular orbital (HOMO) energy levels of the resulting polymer films are affected by the 4‐aryl substituents. The π‐conjugated polymer thin films exhibit electrochromism, where the color of the polymer film turns from yellow to blue by oxidation.
Periodically Grafted Linear–Hyperbranched Copolymers Based on Polyethylene and Polyglycidol: Importance of the Architecture on Properties

Published: August 2017

AbstractHere, the periodically grafted linear–hyperbranched copolymers (LHGCs) based on polyethylene (PE) and hyperbranched polyglycidol is synthesized via acyclic diene metathesis polymerization and anionic ring‐opening multibranching polymerization. The chemical composition of LHGCs can be controlled by changing the amount of the initial monomer. For the first time this allows to control the architecture (composition and sequence distribution), in which the run length between adjacent hyperbranched pendants is exact along PE backbone. By comparing with aperiodically grafted analogues, the results clearly show the composition and the sequence distribution of LHGCs is identified as the major factor to influence the thermal stability, crystallinity as well as hydrophilicity.
“Breathing” CO2‐, O2‐, and Light‐Responsive Vesicles from a Triblock Copolymer for Rate‐Tunable Controlled Release

Published: August 2017

AbstractA well‐defined amphiphilic triblock copolymer, poly[(ethylene glycol)methyl ether]‐block‐poly(N,N‐dimethylamino ethyl methacrylate‐co‐2,2,2‐trifluoroethyl methacrylate)‐block‐poly(4‐(4‐methoxy‐phenylazo)phenoxy methacrylate) (PEG‐b‐P(DMAEMA‐co‐TFEMA)‐b‐PMEPPMA), is successfully synthesized by stepwise atom transfer radical polymerization. Owing to its amphiphilic nature, PEG‐b‐P(DMAEMA‐co‐TFEMA)‐b‐PMEPPMA can self‐assemble into vesicles in aqueous solution and exhibits a reversible triple‐responsive behavior toward CO2, O2, and light stimuli. More importantly, such vesicles can exhibit a controlled “breathing” behavior via external stimuli due to their suitable chemical structure and stimuli responsiveness. Consequently, these vesicles can be employed as nanocarriers for rate‐tunable controlled release via adjustment of their membrane permeability by a single stimulus or various stimuli combinations.

BackgroundThe purpose of this study was to identify which triple immunosuppressive protocols, currently used for vascularized composite allotransplantation in the clinic, will have the best effect on motor function recovery following nerve allograft reconstruction.MethodsEighty‐eight Lewis rats underwent a 1‐cm sciatic nerve allograft transplantation and skin graft from 44 Brown‐Norway rats. Group I received 0.9% isotonic saline (control); Group II, 2 mg/kg FK506; Group III, 1 mg/kg FK506 with 15 mg/kg mycophenolate mofetil (MMF); and Group IV, 2 mg/kg FK506 with 30 mg/kg MMF and prednisone. Each group consisted of 11 rats. After 12 weeks, motor function recovery was evaluated with isometric tetanic force, muscle mass, ankle contracture angle, electrophysiology, and nerve histomorphometry. Adequacy of immunosuppression was monitored with the transplanted skin graft. All data are expressed as a percentage of the contralateral side.ResultsIsometric tetanic force showed significantly better functional recovery in all groups treated with immunosuppression compared to control. Within the immunosuppression groups no significant difference was found: 42.1 ± 6.4% (Group I), 56.1 ± 12.4% (Group II), 58.4 ± 10.7% (Group III), and 61.3 ± 11.2% (Group IV). Group IV was superior to all other groups regarding ankle contracture (P < .05) and electrophysiology (P < .001). Skin graft rejection occurred in 41 and 0% (Groups III and IV, respectively).ConclusionsFK506 significantly enhanced motor recovery after allograft reconstruction. This effect was comparable between combination treatment (low‐dose FK506 and MMF) and triple therapy (high‐dose FK506 and MMF plus prednisolone). However, triple therapy was more effective in suppressing skin rejection.
Evaluation and management of tethered cord syndrome in occult spinal dysraphism: Recommendations from the international children's continence society

Published: August 2017

AimsAs awareness and frequency of tethered spinal cord (TSC) related to occult spinal dysraphism (OSD) has increased with magnetic resonance imaging (MRI), variability exists in its evaluation and management. Due to no published level I data, we summarize the current International Children's Continence Society (ICCS) recommendations for diagnosis and treatment of OSD.MethodsGuidelines were formulated based on analysis of pertinent literature and consensus among authors. This document was vetted by the multidisciplinary members of the ICCS via its website before submission for peer review publication.ResultsThe more frequent diagnosis of OSD is associated with increased operative intervention. Spinal cord untethering (SCU) has a highly variable risk profile, largely dependent on the specific form of OSD. Progressive neurological deterioration attributed to “tethered cord” may occur, with or without surgery, in selected forms of OSD whereas other cohorts do well.ConclusionInfants with classic cutaneous markers of OSD, with progressive neurologic, skeletal, and/or urologic findings, present no diagnostic or therapeutic dilemma: they routinely undergo MRI and SCU. Conversely, in asymptomatic patients or those with fixed, minor abnormalities, the risk profile of these OSD cohorts should be carefully considered before SCU is performed. Irrespective of whether or not SCU is performed, patients at risk for progression should be followed carefully throughout childhood and adolescence by a multidisciplinary team.

Published: August 2017

AbstractThe synthesis of metal sulfide (MS) materials with sizes in the sub‐10 nm regime often requires capping agents with long hydrocarbon chains that affect their structures and properties. Herein, this study presents a molten‐state synthesis method for a series of transition‐MS nanoparticles using thiourea as a reactive precursor without capping agents. This study also reports the synthesis of MS with single metals (Fe, Co, Ni, Cu, and Zn) and quaternary CuGa2In3S8 using the same synthesis protocol. Thiourea first melts to form a molten‐state condition to serve as the reaction medium at a relatively low temperature (<200 °C), followed by its thermal decomposition to induce a reaction with the metal precursor to form different MS. This synthesis protocol, owing to its dynamic characteristics, involves the formation of a variety of organic carbon nitride polymeric complexes around the MS particles. Dynamic nuclear polarization surface‐enhanced nuclear magnetic resonance spectroscopy is effective to identify the polymeric compositions and structures as well as their interactions with the MS. These results provided thorough structural descriptions of the MS nanoparticles surrounded by the carbon nitride species derived from thiourea, which may find various applications, including photocatalytic water splitting.

AbstractResearch on the home literacy environment has typically involved parents as teachers with little attention given to siblings’ roles in teaching each other. This study examines naturalistic language and literacy teaching by 39 sibling dyads, at two timepoints, when children were ages 2 and 4 (time 1; T1) and again at ages 4 and 6 (time 2; T2). Each family was observed for a total of six 90‐minute sessions at both timepoints. First, all sibling‐directed teaching sequences were identified, including instances of formal and informal teaching. Second, sequences were coded for evidence of language (i.e., vocabulary, book concepts, songs, phonological awareness) and literacy concepts (i.e., alphabetic principle, reading, writing, spelling). Over 40% of the T1 and T2 teaching sequences involved language and literacy concepts. Older siblings taught the majority of the time at T1 and T2; however, the number of sequences taught by younger siblings increased proportionally over time. Because siblings taught vocabulary concepts significantly most often at both T1 and T2, further analyses were conducted on vocabulary subcategories (i.e., expansion, discussing pictures, relaying word meaning, checking for listener understanding, second‐language instruction). Significantly more teaching sequences involved expansion than other vocabulary subcategories at both timepoints. Finally, at T2, literacy concepts (i.e., writing, spelling) were taught significantly more than at T1. Our findings demonstrate that siblings are interested in teaching each other a variety of language and literacy concepts during naturalistic interactions in the home, indicating that siblings contribute to the richness of the home literacy environment.

AbstractSynthesis of quinolinyl pyrazole analogues by ring functionalization as well as molecular hybridization strategy is adopted. Diverse functional groups were assembled around the privileged scaffold viz., 2‐methyl‐3‐(1H‐pyrazol‐5‐yl)quinoline. A series of quinolinyl pyrazole analogues with 1,4‐disubstituted 1,2,3‐triazole moiety, were synthesized employing Click reaction conditions. All 29 synthesized were evaluated for antitubercular activity against Mycobacterium smegmatis strain; wherein eight compounds were active and two promising. Compounds also exhibited the low cytotoxicity against A549 cell line.

Published: August 2017

AbstractMembranes containing a photosensitizer molecule as part of the selective layer are proposed with demonstrated anti‐biofouling activity. For the membrane preparation, mixtures of an amine‐functionalized photosensitizer molecule, (5,10,15,20‐(tetra‐4‐aminophenyl)porphyrin) and m‐phenylene diamine (MPD) reacted with trimesoyl chloride (TMC) by interfacial polymerization to form thin polyamide films on top of an asymmetric porous support. A highly permeable membrane (35.4 Lm−2h−1bar−1) with 99 % rejection of Brilliant Blue R (826 g/mol) was obtained using 0.25 wt% porphyrin and 0.75 wt% MPD as amine monomers. Under visible light exposure, singlet oxygen (1O2) is generated in the porphyrin containing‐polyamide film, reaching the bacteria in the feed by diffusion and enhancing the biofouling resistance and anti‐microbial activity. Anti‐biofouling and anti‐microbial photoactivity in solution are demonstrated on Staphylococcus aureus at different porphyrin concentrations and light exposure time.

Published: August 2017

AbstractA series of spiro‐annulated triphenylamine/N‐phenylcarbazole derivatives as ambipolar host molecules have been designed by linking different electron acceptors (i. e., diphenylphosphine, phenylsulfone, triphenylsilane and diphenylborane). To reveal their electronic structures, optoelectronic properties and structure‐property relationships of the host materials, a throughout investigation was implied using density functional theory (DFT) and time‐dependent density functional theory (TDDFT) calculations. Results show that the triplet energy (ET), HOMO and LUMO energy levels, as well as some other properties i. e. ionization potentials (IPs), electron affinities (EAs), reorganization energies (λ) can be tuned by chemical modifications of different electron acceptors. The host‐guest models have also been built to investigate the match of the hosts and the reference guests. Comprehensively considering these indexes, the potential performance of 10‐phenyl‐2′‐(phenylsulfonyl)‐10H‐spiro[acridine‐9, 9′‐fluorene] (SOSTF) is a big leap in comparison with experimental host material diphenyl(10‐phenyl‐10H‐spiro[acridine‐9, 9′‐fluoren]‐2′‐yl)phosphine oxide (POSTF). It has been proved that a spiro‐annulated structure can be modified in constructing high ET host material for blue phosphorescent organic light‐emitting diodes.

AbstractWe report a metal‐free, oxidant‐free, highly regioselective halogenations protocol (chlorination, bromination and iodination) to amidoquinolines using N‐halosaccharin derivatives. Various amidoquinolines are tolerated by the method and delivered C5‐haloamidoquinoline derivates in excellent yields. A homo and hetero bis‐halogenation protocol has also been established. Late stage drug molecule diversification has also been demonstrated using the developed protocol.
An adaptive numerical scheme based on the Craig–Bampton method for the dynamic analysis of tall buildings
Authors: Fang Ming , Wang Jian , Li Hui 
Published: August 2017

SummaryA new numerical scheme is proposed to perform a nonlinear dynamic analysis for tall buildings. The structural components (beams and columns) of tall buildings gradually enter the inelastic phase under strong seismic excitation. Because the distribution of nonlinear components is initially unknown due to the randomness of earthquake inputs, a group of linear and nonlinear substructures are automatically figured out during the time‐history analysis of a structure. Then a modified Craig–Bampton method is proposed to condense the DOFs of the linear substructures in modal coordinates at each time step while keeping the governing equation of the nonlinear substructure in physical coordinates. The dominant modes of the linear substructures are selected to capture the main dynamic characteristics of the structure. The time step integration analysis is used to solve the governing equation of the structures in hybrid coordinates. A 20‐story building is employed as the numerical simulation test to validate the feasibility and effectiveness of the proposed numerical scheme. This scheme provides a new method for the nonlinear dynamic analysis of tall buildings with acceptable simulation accuracy and high computational efficiency.
