Consumer Regulation Strategies: Attenuating the Effect of Consumer References in a Voting Context
Authors: Whelan Jodie , Goode Miranda R. , Cotte June , Thomson Matthew 
Published: October 2016

ABSTRACTConsumption cues (e.g., brands, money, and advertisements) can have powerful effects on cognition, perception, and behavior, yet how people regulate responses to such cues is not well understood. This is surprising given that consumption cues are increasingly present in nontraditional consumer contexts, such as healthcare, education, and politics. This research develops a measure of two types of consumer regulation strategies, cue‐based and budget‐based (studies 1–4), and demonstrates that these strategies influence how people respond to consumption cues in a political context (study 5). Specifically, in a study involving the 2012 American Presidential Election, priming survey participants as consumers (versus citizens) influenced both voting intentions and self‐reported voting behavior, and the newly developed consumer regulation scale was instrumental in detecting this effect. These findings suggest there may be merit in the escalating debate and concern over referring to voters as consumers.
Legacy Writing and the Consumption of Biographic Services
Authors: Guillemot Samuel , Urien Bertrand 
Published: October 2016

ABSTRACTThis study focuses on legacy writing and the development of the life‐history business (e.g., family ghostwriters and writing workshops). A theoretical model is proposed to study the underlying mental processes that lead the elderly to consume such services. This model was empirically tested on a sample of 392 individuals aged from 60 to 92 years. Results highlighted the following: the role of generativity and death preparation reminiscence on identity preservation issues in later life, the strong desire to contribute to collective memories (i.e., to reach people outside of the family circle), and the social nature of the consumption of services that could be considered as a means of sharing emotions. The results of this study will lead to a more in‐depth understanding of consumer behavior regarding the transmission and preservation of the self at end of life, and may also help service providers to improve their products and services.
A Comprehensive Typology of Prepurchase, External Information Searchers
Authors: D'Rozario Denver 
Published: October 2016

ABSTRACTVarious studies in the information search literature in the past have uncovered differing sets of prepurchase external‐information search patterns exhibited by individuals. However, across all these studies there has been little consistency not only in these reported patterns, but also in the terminology used to describe each of them. This paper seeks to address this major gap in the literature. Based on an exhaustive review of the prior empirical literature on prepurchase information search patterns, for the first time in the literature, a comprehensive supertypology is proposed in this paper that accounts for all the searcher types reported in this prior literature. Further, also for the first time in the literature, this paper seeks to explain these searcher types using an accepted theoretical framework. As must be pointed out, all of the prior searcher types uncovered (and reviewed in this paper) were empirically driven and devoid of theory. In this paper, also for the first time in the literature, testable, theory‐based propositions are developed for each searcher type in the proposed typology. Finally, this paper concludes with a discussion as to why this typology is needed and how it could be used by practitioners and theoreticians in marketing.
Physical Microfabrication of Shape‐Memory Polymer Systems via Bicomponent Fiber Spinning
Authors: Tallury Syamal S. , Pourdeyhimi Behnam , Pasquinelli Melissa A. , Spontak Richard J. 
Published: October 2016

As emerging technologies continue to require diverse materials capable of exhibiting tunable stimuli‐responsiveness, shape‐memory materials are of considerable significance because they can change size and/or shape in controllable fashion upon environmental stimulation. Of particular interest, shape‐memory polymers (SMPs) have secured a central role in the ongoing development of relatively lightweight and remotely deployable devices that can be further designed with specific surface properties. In the case of thermally‐activated SMPs, two functional chemical species must be present to provide (i) an elastic network capable of restoring the SMP to a previous strain state and (ii) switching elements that either lock‐in or release a temporary strain at a well‐defined thermal transition. While these species are chemically combined into a single macromolecule in most commercially available SMPs, this work establishes that, even though they are physically separated across one or more polymer/polymer interfaces, their shape‐memory properties are retained in melt‐spun bicomponent fibers. In the present study, we investigate the effects of fiber composition and cross‐sectional geometry on both conventional and cold‐draw shape memory, and report surprisingly high levels of strain fixity and recovery that generally improve upon strain cycling.image
Molecular Weight Distribution of Ethylene/1‐Olefin Copolymers: Generalized Bimodality Criterion
Authors: Vichitlimaporn Charut , Anantawaraskul Siripon , Soares João B. P. 
Published: October 2016

Two single‐site‐type metallocene catalysts can be combined to produce polymers with well‐controlled and broad molecular weight distributions (MWD). As polyolefins with unimodal and bimodal MWDs have different mechanical and rheological properties, a criterion to determine whether a system of two single‐site‐type catalysts produces polymers with unimodal or bimodal distributions is useful for product development and property optimization. In this work, a generalized MWD bimodality criterion is developed and represented as a comprehensive 3D map. The proposed criterion is validated with both simulated and previously reported experimental data. The effect of number average chain length and mass fraction on MWD bimodality criteria are also examined. The results show that unimodal MWDs are more likely to be observed when the mass fraction of one of the copolymers is much higher than the other and when both copolymers have similar average chain lengths.

Experimentally Calibrated Random Walk of Branched Polymers: A Pragmatic Approach
Authors: Hosemann Benjamin , Drache Marco , Beuermann Sabine 
Published: October 2016

In order to control the branching behavior of polymers, the comparison of experimental and simulated data is important. The utilization of a nonlattice, self‐avoiding necklace‐bead random walk simulator is reported, which allows for the calculation of radii of gyration r
g of polymer molecules with branched structures. The focus is on sensitivity toward short‐chain branches, long‐chain branches (LCBs), and the copolymer composition. Using only two parameters—the size of monomer beads and the minimum angle between three subsequent beads—a fast and reliable parameter fit procedure based on experimental data is described. The procedure is exemplarily shown for copolymers of vinylidene fluoride and hexafluoropropene (HFP) with HFP contents in the copolymer of at most 0.3 and is easily transferable to other polymers that may be analyzed by size‐exclusion chromatography/multiangle laser light scattering close to θ conditions. Applying the Zimm–Stockmayer equation to simulated r
g data allows for comparing the “effective” number of LCBs with the number of LCBs given by kinetic simulations. A tool for better estimation of rate coefficients associated with the formation of short‐ and long‐chain branches is provided.image

Published: October 2016

ScopeThe scope of the present study was to investigate the effects of red versus white meat intake on the metabolome of rats.Methods and resultsTwenty‐four male Sprague–Dawley rats were randomly assigned to 15 days of ad libitum feeding of one of four experimental diets: (i) lean chicken, (ii) chicken with lard, (iii) lean beef, and (iv) beef with lard. Urine, feces, plasma, and colon tissue samples were analyzed using 1H NMR‐based metabolomics and real‐time PCR was performed on colon tissue to examine the expression of specific genes. Urinary excretion of acetate and anserine was higher after chicken intake, while carnosine, fumarate, and trimethylamine N‐oxide excretion were higher after beef intake. In colon tissue, higher choline levels and lower lipid levels were found after intake of chicken compared to beef. Expression of the apc gene was higher in response to the lean chicken and beef with lard diets. Correlation analysis revealed that intestinal apc gene expression was correlated with fecal lactate content (R2 = 0.65).ConclusionThis study is the first to identify specific differences in the metabolome related to the intake of red and white meat. These differences may reflect perturbations in endogenous metabolism that can be linked to the proposed harmful effects associated with intake of red meat.

Published: October 2016

PurposePelvic lymph node (PLN) metastases are often smaller than 5 mm and difficult to detect. This work presents a method to perform PLN imaging with ultrahigh‐field MRI, using spectrally selective excitation to acquire water and lipid‐selective imaging at high spatial resolution.MethodsA 3D water‐selective multigradient echo (mGRE) sequence and lipid‐selective gradient echo (GRE) sequence were tested in six healthy volunteers on a 7 Tesla (T) MRI system, using time interleaved acquisition of modes (TIAMO) to improve image homogeneity. The size distribution of the first 10 iliac PLNs detected in each volunteer was determined, and the contrast‐to‐noise ratio (CNR) of these lymph nodes (LNs) was compared with the individual mGRE images, sum‐of‐squares echo addition, and computed
‐weighted images derived from the
fits.ResultsLN imaging was acquired robustly at ultrahigh field with high resolution and homogeneous lipid or water‐selective contrast. PLNs down to 1.5‐mm short axis were detected with mean ± standard error of the mean (SEM) short and long axes of 2.2 ± 0.1 and 3.7 ± 0.2 mm, respectively. Computed
‐weighted imaging allowed flexibility in
contrast while featuring a CNR up to 90% of the sum‐of‐squares echo addition.ConclusionUltrahigh‐field MRI in combination with TIAMO and frequency‐selective excitation enables high‐resolution, large field‐of‐view MRI of the lower abdomen, and may ultimately be suitable for detecting small PLN metastases.

AbstractPurposeTo analyze and characterize data regarding the prevalence and types of outpatient drug‐related problems (DRPs) found by clinical pharmacists after implementation of the Virtual Medicine Record in Cloud System (VMRCS).MethodsA cross‐sectional study regarding outpatient pharmaceutical care was conducted at a medical center in Taiwan. Patients aged >20 years old with multiple chronic diseases and polypharmacy were enrolled. In Stage I (1 October–31 December 2014), patients received pharmaceutical care according to prescription data accessed online in the VMRCS. In Stage II (1 June–31 August 2015), the VMRCS were pre‐download and arranged to the institute's required format, facilitated DRP detection. Clinical pharmacists then reviewed and evaluated the prescription data through pre‐downloaded VMRCS. Overall, 1539 and 1600 prescriptions were evaluated in these two stages, respectively. DRPs were recorded using the Pharmaceutical Care Network Europe (PCNE)‐DRP.ResultsDRPs were found for 50.2% of patients in Stage I and 55.2% in Stage II (p < 0.05) and were most frequently encountered for “Drugs for the cardiovascular system” and caused by “Inappropriate duplication of therapeutic group or active ingredient.” In terms of problems, incidence of “Unnecessary drug treatment” was highest. Duplicate medications were most frequently seen for “Drugs for acid‐related disorders.” The efficiency to identify DRPs was at least 2.4 times higher with pre‐downloaded prescription data than with real‐time online queries.ConclusionsWith VMRCS, DRPs were more easily identified whether patients received medical care in the same hospital or not. DRPs could be efficiently prevented through the use of pre‐downloaded patient prescription data. Copyright © 2016 John Wiley & Sons, Ltd.
Recent approaches in designing bioadhesive materials inspired by mussel adhesive protein
Authors: Kord Forooshani Pegah , Lee Bruce P. 
Published: October 2016

ABSTRACTMarine mussels secret protein‐based adhesives, which enable them to anchor to various surfaces in a saline, intertidal zone. Mussel foot proteins (Mfps) contain a large abundance of a unique, catecholic amino acid, Dopa, in their protein sequences. Catechol offers robust and durable adhesion to various substrate surfaces and contributes to the curing of the adhesive plaques. In this article, we review the unique features and the key functionalities of Mfps, catechol chemistry, and strategies for preparing catechol‐functionalized polymers. Specifically, we reviewed recent findings on the contributions of various features of Mfps on interfacial binding, which include coacervate formation, surface drying properties, control of the oxidation state of catechol, among other features. We also summarized recent developments in designing advanced biomimetic materials including coacervate‐forming adhesives, mechanically improved nano‐ and micro‐composite adhesive hydrogels, as well as smart and self‐healing materials. Finally, we review the applications of catechol‐functionalized materials for the use as biomedical adhesives, therapeutic applications, and antifouling coatings. © 2016 The Authors.

ABSTRACTFour conjugated polymers (P1–P4) consisting of alternating anthracene‐9,10‐diyl and 1,4‐phenylene building blocks connected via ethynylene as well as vinylene (P1 and P2), ethynylene‐only (P3), and vinylene‐only (P4) moieties, respectively, were synthesized and studied. The phenylene units in all four polymers bear 2‐ethylhexyloxy side‐chains to promote good solubility. The three polymers with vinylene units (P1, P2, and P4) were prepared using the Horner–Wadsworth–Emmons reaction. For the synthesis of the arylene‐ethynylene polymer P3, the palladium‐catalyzed Sonogashira cross‐coupling reaction was used. The polymers were characterized by NMR, Fourier transform infrared spectroscopy, and Raman spectroscopy. Photophysical, absorption and photoluminescence, and electrochemical properties were studied. Spectroscopic ellipsometry measurements were performed to gain more insight on the optical properties. In addition, the transport properties were investigated using admittance spectroscopy. The bulk hole mobility and its dependence on the electric field were evaluated for P1 and P2. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2017, 55, 129–143
Radical‐medicated end‐group transformation of amphiphilic methacrylate random copolymers for modulation of antimicrobial and hemolytic activities
Authors: Nadres Enrico T. , Takahashi Haruko , Kuroda Kenichi 
Published: October 2016

ABSTRACTThis work describes synthesis of antimicrobial methacrylate copolymers by reversible addition‐fragmentation chain transfer (RAFT) polymerization and examines the versatility of this approach for improving chemical optimization to create potent, non‐toxic antimicrobial polymers. Specifically, this study focuses on the radical‐mediated transformation of end group of antimicrobial peptide‐mimetic polymer. RAFT polymerization using 2‐cyano‐2‐yl‐dithiobenzoate provided a statistical methacrylate copolymer consisting of aminobutyl and ethyl groups in the side chains. The following radical‐mediated modification using free radical initiators successfully transformed the ω‐end group of parent copolymer from dithiobenzoate to a cyanoisobutyl or aminoethyl cyanopentanoate group without any significant changes to the polymer molecular weight. In general, the parent polymer and variants showed a broad spectrum of activity against a panel of bacteria, but low hemolytic activity against human red blood cells. The parent copolymer with the dithiobenzoate end‐group showed highest antimicrobial and hemolytic activities as compared with other copolymers. The copolymers caused membrane depolarization in Staphylococcus aureus, while the ability of copolymers for membrane disruption is not dependent on the end‐group structures. The synthetic route reported in this study will be useful for further study of the role of polymer end‐groups in the antimicrobial activity of copolymers. © 2016 Wiley Periodicals, Inc. J. Polym.

Published: October 2016

AbstractPurposeA proportion of newly diagnosed cancer patients may experience anxiety and depression. Emotion suppression has been associated with poorer psychoemotional outcomes, whereas reappraisal may be an adaptive emotion regulation strategy. Few studies have examined potential mechanisms linking reappraisal to psychoemotional outcomes in cancer patients. This study aims to replicate findings on reappraisal and suppression and further examines if hope mediates the association between reappraisal and anxiety/depression in patients newly diagnosed with cancer.MethodsParticipants were 144 adult cancer patients (65.3% female, mean age = 48.96 years, SD = 9.23). Patients completed a set of study questionnaires, including the Emotion Regulation Questionnaire, Adult Hope Scale, and the Hospital Anxiety and Depression Scale. Path analysis was used to examine if hope mediated the association between reappraisal and anxiety/depression.ResultsPrevalence of anxiety was 39.6% and depression was 25.0%. Reappraisal and hope were correlated with lower anxiety and depression, whereas suppression was correlated with higher anxiety and depression. The hypothesized mediation model provided fit to the data, comparative fit index = 0.95, Tucker‐Lewis index = 0.94, root‐mean‐square‐error of approximation = 0.05. There was a significant indirect effect of reappraisal on anxiety and depression via hope, b = −0.95, SE = 0.42, 95% confidence interval = −1.77 to −0.12, whereas the direct effect of reappraisal was nonsignificant.ConclusionThe study findings suggest that hope mediated the association between reappraisal and anxiety/depression outcomes. Moreover, the high prevalence of anxiety and depression implies a need for healthcare providers to attend to the psychoemotional needs of newly diagnosed cancer patients.

SummaryIntroductionHome ventilation (HV) for children is growing rapidly worldwide. The aim was to describe (1) the sociodemographic characteristics of children on HV and (2) the indications for, means and outcome of initiating HV in children from a developing country.MethodologyThis retrospective study included patients sent home on noninvasive or invasive ventilation, over 13 years, by the pediatric respiratory unit in a single center. Children who declined treatment were excluded.ResultsSeventy children were initiated on HV: 85.7% on noninvasive ventilation, 14.3% on invasive ventilation. There was about a threefold increase from 2001–2008 (n = 18) to 2009–2014 (n = 52). Median (range) age of initiating HV was 11 (1–169) months and 73% of children were <2 years old. Common indications for HV were respiratory (57.2%), chest/spine anomalies (11.4%), and neuromuscular (10.0%). Fifty‐two percent came off their devices with a median (interquartile range) usage duration of 12 (4.8, 21.6) months. Ten children (14.3%) died with one avoidable death. Children with neuromuscular disease were less likely to come off their ventilator (0.0%) compared to children with respiratory disease (62.1%). Forty‐one percent of parents bought their equipment, whereas 58.6% borrowed their equipment from the medical social work department and other sources.ConclusionHV in a resource‐limited country is possible. Children with respiratory disease made up a significant proportion of those requiring HV and were more likely to be weaned off. The mortality rate was low. The social work department played an important role in facilitating early discharge. Pediatr Pulmonol. 2017;52:500–507. © 2016 Wiley Periodicals, Inc.
