The role of emotions in shaping purchase intentions for innovations using emerging technologies: A scenario‐based investigation in the context of nanotechnology
Authors: Seegebarth Barbara , Backhaus Christof , Woisetschläger David M. 
Published: June 2019

AbstractAlthough emotions may not play a major role as antecedents of consumers′ innovation acceptance, this study proposes that attitude formation works differently in the context of emerging technologies because of their high levels of uncertainty. To investigate the role of emotions in shaping intentions to adopt innovations using emerging technologies, the conceptual model developed in this study integrates cognitive (risks and benefits) and emotional (optimism and worry) elements. A scenario‐based study employing 731 participants tests the model across three nanotechnology‐based product innovations that differ in terms of product category risk. The results of a mediated moderation model show that emotions do play a key mediating role in explaining purchase intentions. Although the study supports the conceptual model regardless of the level of product‐related risk, it finds risk‐related differences in the strength and level of the mediational links. By unveiling the role of emotions in emerging technology contexts, this study has important implications not only for innovation management but also for regulating institutions and public policymakers.

Published: June 2019

AbstractIn this study, we evaluated the role of signal transducer and activator of transcription 1 (STAT1) in response to acute solar ultraviolet (SUV) radiation in mouse epidermis. Analysis of the epidermis from SUV‐irradiated mice revealed rapid phosphorylation of STAT1 (pSTAT1) on both tyrosine (tyr701) and serine (ser727) residues and increased levels of IRF‐1 while later timepoints showed increased levels of unphosphorylated STAT1 (uSTAT1). STAT1 activation led to upregulation of several proinflammatory chemokine mRNAs in epidermis includingCxcl9,Cxcl10, andCcl2,as well as, the immune checkpoint inhibitorPd‐l1. In addition, mRNA and protein levels of cyclooxygenase‐2 (Cox‐2/COX2) were upregulated in epidermis following exposure to SUV. Mice with keratinocyte‐specific STAT1 deletion did not exhibit increased IRF‐1 or proinflammatory gene expression in epidermis. Furthermore, epidermal COX‐2 induction after SUV exposure was significantly reduced in mice with keratinocyte‐specific deletion of STAT1. Additionally, SUV irradiation rapidly upregulated interferon gamma (IFNγ) mRNA in the epidermis and that skin resident epidermal CD3 + T‐cells were the source of IFNγ production. IFNγ receptor‐deficient mice confirmed dependency of STAT1 activation, proinflammatory gene expression and COX‐2 upregulation in the epidermis on paracrine IFNγ signaling. Furthermore, keratinocyte‐specific STAT1‐deficiency reduced proliferation and hyperplasia due to SUV irradiation and this was associated with decreased immune infiltration of mast cells in the dermis. Collectively, the current results demonstrate that exposure to SUV leads to upregulation of IFNγ and downstream pSTAT1/IRF‐1/uSTAT1 signaling in the epidermis. Further study of this pathway could lead to identification of novel targets for the prevention of nonmelanoma skin cancer.

Abstract
Predicted increases in temperatures over the next century have raised many concerns about changes in the life history traits and geographical distributions of anadromous fishes. Anadromous fishes are particularly vulnerable to human activities due to the diverse array of habitats needed to complete their life cycle and the proximity of essential habitats to large human population centers. To understand the potential changes in spawning phenology of American Shad Alosa sapidissima and Striped Bass Morone saxatilis in the Hudson River estuary, a model was developed to estimate the onset, cessation, and duration of the spawning season through the 21st century, corresponding to projected water temperatures. Water temperatures for the Hudson River estuary were determined using recent models accepted by the Intergovernmental Panel on Climate Change. Model results indicate that by the 2090s, the spawning season of both species will initiate, on average, approximately 15 d earlier in the year, with spawning duration reduced by 4 d compared to the average spawning season in the 2010s.

AbstractBackgroundBrain dopamine transporter binding has been considered a possible biomarker for nigrostriatal degeneration in PD.ObjectiveTo investigate whether dopamine transporter binding is associated with the number of dopaminergic neurites in the putamen.MethodsTyrosine hydroxylase–positive nerve fibers were counted from postmortem putamen sections taken from 14 parkinsonism patients who had been scanned with dopamine transporter single‐photon emission computed tomography antemortem. Fiber counts were correlated with putamen dopamine transporter binding and SN neuron counts.ResultsThe putamen dopamine transporter specific binding ratio did not correlate with the putamen tyrosine hydroxylase–positive axon counts (r = 0.00; P = 1.0; PD patients: r = 0.07; P = 0.86). The nigra neuron counts had a positive correlation with the putamen tyrosine hydroxylase–positive axon counts.ConclusionsStriatal dopamine transporter imaging does not associate with axonal nor somal loss of the nigrostriatal neurons in PD. It may reflect dopaminergic activity rather than number of surviving neurons or their striatal projection axons. © 2019 International Parkinson and Movement Disorder Society

Published: June 2019

AbstractBackgroundWith the ongoing global epidemic of obesity in the Western countries, thigh flaps such as the profunda artery perforator (PAP) free flap, have been less favorable for glossectomy reconstruction due to large bulk of adipose tissue associated with traditional subfascial harvest. In this article, we present a series of 10 patients who underwent reconstruction with suprafascial PAP free flaps following oncologic tongue resection.MethodsOur series included six men and four women with an average age of 53.9 years old (range, 28–71 years). All patients underwent preoperative computed tomographic angiography (CTA) for selection of the most suitable perforator and preoperative design of its customized thickness. Flap elevation was performed at the superficial fascia layer while modifying the plane of dissection according to the specific bulk needs in each case.ResultsFlaps survived in nine patients; one flap failed due to vasospasm. Mean pedicle length was 7.4 cm (range, 6–8 cm). Skin paddle dimensions varied between 8 × 6 and 15 × 9 cm. Flaps thicknesses ranged from 0.4 to 3 cm. Functional outcome was evaluated at 6 months follow up: good speech and deglutition functional outcomes relative to extent of resection were observed.ConclusionsThe dissection above the superficial fascia layer represents an important refinement to the traditional fasciocutaneous PAP flap. Flap thickness can be tailored to avoid excess of bulk in the medial thigh observed in larger BMI populations.

Published: June 2019

AbstractThe design and realization of a compact coplanar waveguide (CPW) fed ultrawideband (UWB) antenna having dual‐notched bands is presented in this article. The antenna possesses on demand notch bands at 4 to 5.78 GHz and 6.83 to 8.22 GHz. The presented design consists of a single iterated octagonal patch antenna designed on cheap FR4 substrate. The stub is utilized to achieve a wide impedance matching of 7.33 GHz (3.2‐10.5 GHz), while the notch‐bands are realized using split ring circular slots. These notch‐bands are controlled independently without affecting the overall performance of the antenna. Simulated and measured results showed that the antenna offers excellent performance with an overall size of 20 × 23 mm2, high efficiency of more than 90%, and a nearly omnidirectional maximum gain of 4.8 dBi. The performance of the proposed antenna is better than the antennas presented in the literature in term of size, stable gain, and independently controllable notch bands. Besides these advantages, the compact size allows the antenna to integrate into small devices easily and help manufacturers to produce a massive number of antennas comfortably.

Published: June 2019

AbstractA series of copolyarylates (PP0–PP100) containing phthalide groups was synthesized via interfacial polymerization from a mixture of phenolphthalein (PP) and bisphenol A with molar equivalent of terephthalyl chloride. Incorporating PP into the polymer chain improved the solubility of the polyarylates in common organic solvents. The glass transition temperature (191–314 °C), residual weight percentage, Young's modulus (1.7–2.8 GPa), solubility and complex melt viscosity of the copolyarylates increased with increasing PP units in the copolymerization. By contrast, crystallinity and elongation at break (14.1 to 11.2%) of the copolyarylates decreased with increasing PP units in the polymer backbone. When the PP content increased over 30 mol% (PP30), the copolyarylates became amorphous polymers. When the PP content was below 30 mol%, the copolyarylates exhibited good melt processability. With regards to its solubility, thermal stability, mechanical properties and melt processability, PP30 may be considered as a promising candidate in the field of processable high‐performance engineering plastics. © 2019 Society of Chemical Industry

AbstractA body of research suggests that child maltreatment may not represent an uncommon phenomenon. Adverse childhood experiences have been consistently linked to a variety of mental disorders, including personality disorder. Starting from these considerations, we aimed at testing the associations between retrospective self‐reports of childhood abuse and Personality Inventory for DSM‐5 (PID‐5) traits and domains in a sample of community‐dwelling adult participants (N = 369; 41.2% male). PID‐5 scales yielded 63 (52.5%) rank‐order correlations with self‐reports of childhood abuse that were significant at Bonferroni‐corrected p level (i.e. p < 0.00042), with values ranging from 0.18 to 0.36. According to Fisher's z‐test for correlation coefficient homogeneity, the wide majority of the correlations were reproduced across male participants and female participants. Partial rank‐order correlation analyses highlighted specific personality profiles that were uniquely, albeit modestly associated with memories of childhood abuse. Confirming and extending previous findings, our results showed that retrospective reports of childhood abuse are significantly, albeit moderately associated with different dysfunctional personality traits, at least in Italian community‐dwelling adults. As a whole, our data seemed to stress the importance of PID‐5 traits and domains in improving our understanding of the relationships between self‐reports of childhood abuse and dysfunctional personality dimensions in adulthood. © 2019 John Wiley & Sons, Ltd.

The 3A6‐TCR/superagonist/HLA‐DR2a complex shows similar interface and reduced flexibility compared to the complex with self‐peptide
Authors: Salutari Ilaria , Martin Roland , Caflisch Amedeo 
Published: June 2019

AbstractT‐cell receptor (TCR) recognition of the myelin basic protein (MBP) peptide presented by major histocompatibility complex (MHC) protein HLA‐DR2a, one of the MHC class II alleles associated with multiple sclerosis, is highly variable. Interactions in the trimolecular complex between the TCR of the MBP83‐99‐specific T cell clone 3A6 with the MBP‐peptide/HLA‐DR2a (abbreviated TCR/pMHC) lead to substantially different proliferative responses when comparing the wild‐type decapeptide MBP90‐99 and a superagonist peptide, which differs mainly in the residues that point toward the TCR. Here, we investigate the influence of the peptide sequence on the interface and intrinsic plasticity of the TCR/pMHC trimolecular and pMHC bimolecular complexes by molecular dynamics simulations. The intermolecular contacts at the TCR/pMHC interface are similar for the complexes with the superagonist and the MBP self‐peptide. The orientation angle between TCR and pMHC fluctuates less in the complex with the superagonist peptide. Thus, the higher structural stability of the TCR/pMHC tripartite complex with the superagonist peptide, rather than a major difference in binding mode with respect to the self‐peptide, seems to be responsible for the stronger proliferative response.

AbstractVariability in abiotic and biotic factors during larval stages has profound impacts on fish recruitment. In Lake Michigan, where the composition of lower trophic levels has undergone considerable changes in the past decade, managers are concerned that fish recruitment could be negatively affected. We hypothesized that spatial variation in Lake Michigan larval fish density and growth can be explained by various environmental predictor variables. In July 2015, we sampled larval fish and zooplankton at 24 sites (distributed among eight transects) around Lake Michigan. We measured larval fish densities and estimated growth rates and diets of the two most abundant species: the AlewifeAlosa pseudoharengusand BloaterCoregonus hoyi(prey fish that represented 89% and 4% of the total catch, respectively). Larval Alewife densities at a given site ranged from 0 to 42.57 larvae/100 m3, but no explanatory variables explained the variation. Alewife mean growth rate equaled 0.50 mm/d, and fish age and zooplankton density best explained growth variation across sites. Larval Bloater densities ranged from 0 to 1.16 larvae/100 m3, and mean growth rate was 0.21 mm/d. Across all sites, 67% of larval Alewife stomachs were empty, whereas only 16% of Bloater stomachs were empty. Larval fish growth rates observed in our study were at least 40% slower than those reported in previous decades for both Alewife and Bloater. Worsening prey environment for pelagic larvae, such as Alewife and Bloater, during the era of abundant dreissenid mussels could reduce the probability of strong year‐classes, which in turn may affect growth and survival of recreationally important salmonine predators.

ABSTRACTObjectiveTo assess the accuracy of preoperative ultrasound examination for predicting lymph‐node (LN) status in patients with vulvar cancer.MethodsThis was a single‐institution retrospective observational study of all women with a histological diagnosis of vulvar cancer triaged to inguinal surgery within 30 days following ultrasound evaluation between December 2010 and January 2016. For each groin examined, 15 morphological and dimensional sonographic parameters associated with suspicion for LN involvement were examined. A morphometric ultrasound pattern (MUP) was expressed for each groin, classifying the inguinal LN status into five groups (normal; reactive‐but‐negative; minimally suspicious/probably negative; moderately suspicious; and highly suspicious/positive) according to subjective judgment, followed by stratification as positive or negative for metastasis according to morphometric binomial assessment (MBA). In cases of positive MBA, fine‐needle aspiration cytology was performed. Combining the information obtained from MUP and cytologic results, a binomial final overall assessment (FOA) was assigned for each groin. The final histology was considered as the reference standard. Comparison was performed between patients with negative and those with positive LNs on histology, and receiver‐operating‐characteristics curves were generated for statistically significant variables on univariate analysis, to evaluate their diagnostic ability to predict negative LN status.ResultsOf 144 patients included in the analysis, 87 had negative inguinal LNs and 57 had positive LNs on histology. A total of 256 groins were analyzed, of which 171 were negative and 85 showed at least one metastatic LN on histology. The following parameters showed the greatest accuracy, with the best balance between specificity and sensitivity, in predicting negative LN status: cortical (C) thickness of the dominant LN (cut‐off, 2.5 mm; sensitivity, 90.0%; specificity, 77.9%); short‐axis (S) length of the dominant LN (cut‐off, 8.4 mm; sensitivity, 63.9%; specificity, 90.6%); C/medulla (M) thickness ratio of the dominant LN (cut‐off, 1.2 mm; sensitivity, 70.4%; specificity, 91.5%), the combination of S length and C/M thickness ratio (sensitivity, 88.9%; specificity, 82.4%); and the FOA analysis (sensitivity, 85.9%; specificity, 84.2%).ConclusionsPreoperative ultrasound assessment, with or without the addition of cytology, has a high accuracy in assessing inguinal LN status in patients with vulvar cancer. In particular, the combination of two ultrasound parameters (S length and C/M thickness ratio) provided the greatest accuracy in discriminating between negative and positive LNs.

A new method for spatial allocation of turbines in a wind farm based on lightning protection efficiency

Published: June 2019

AbstractExisting studies of the spatial allocation of wind farms are typically based on turbine power generation efficiency and rarely consider the damage caused by lightning strikes. However, lightning damage seriously affects the economic performance of wind farms because of the high cost of repairing or replacing damaged blades. This paper proposes a method for the spatial optimization of multiple turbines based on lightning protection dependability. Firstly, the lightning protection efficiency of turbine blade protection systems is analyzed by combining the physical mechanisms of lightning leader progression with a conventional electro‐geometric model to develop an electro‐geometric model of turbine blades (EGMTB). Then, the optimized spatial allocation of multiple turbines in a wind farm is investigated using the EGMTB. The results are illustrated from an example wind farm with 1.5 MW turbines, which shows that the optimal spacing between two turbines perpendicular to the prevailing wind direction L⊥ is 4R‐6R, where R is the length of a turbine blade. This spacing is shown to effectively shield turbine blades from lightning damage over a wide range of lightning currents (>26‐60 kA). Note that, the suggested L⊥ will be smaller considering the influence of lightning polarity as it takes more difficulty developing upward leader (UL) in the condition of positive lightning striking. Experiments verify the effectiveness and correctness of this method.
