When goliaths win and davids lose: The moderating role of perceived risk in brand biography effects

Brand biographies trace a brand’s evolution to position it as an underdog (i.e., passion and determination that lead to success despite of limited resources) or a topdog (i.e., success based on abundance of resources) brand. This research examines how consumers’ risk perceptions associated with brand choice influence brand biography effects. In two studies, the authors demonstrate that when perceived risk associated with brand choice is low, consumers process brand biographies narratively, and underdog (vs. topdog) brand biographies lead to higher levels of narrative transportation, resulting in more favorable brand evaluations. When perceived risk associated with brand choice is high, however, consumers respond more positively to topdog (vs. underdog) brand biographies, which signal brand’s ability to reduce the risk associated with brand choice. Importantly, the topdog effect observed at higher levels of perceived risk reverses when consumers have the opportunity to process the brand biography prior to receiving high risk information, as this allows for narrative transportation into the brand biography. This research contributes to a more nuanced understanding of consumer reactions to brand biographies and suggests that perceived risk should be an important determinant in the marketers’ choice of emphasizing the topdog or underdog characteristics of their brand biography.
Investigation on the thermal performance of phase change material/porous medium‐based battery thermal management in pore scale

With the latent heat, the phase change material (PCM) is widely used in battery thermal management (BTM) to control the temperature. In this paper, the porous medium is employed to enhance the heat transfer of PCM. The lattice Boltzmann model for PCM/porous medium in pore scale is considered, where the mesh system with porous medium (fixed point) is generated by quartet structure generation set (QSGS) method. The effects of the Rayleigh number and porosity on the heat transfer process in BTM are investigated. The results show that decreasing the porosity will accelerate the melting rate. When the porosities are 0.9, 0.8, 0.7, and 0.6, the total melting times are decreased by 23.7%, 43.3%, 58.0%, and 75.4%, compared with pure PCM. The heat is transferred through the high‐conductivity framework. The natural convection in the porous medium is weak, and the conduction is the dominated heat transfer. As a result, the area of solid–liquid interface will be increased, and the heat‐transferred rate is accelerated. However, when the Rayleigh number is raised to 105, applying the porous medium with porosity of 0.9 will increase the total melting time, resulted from the stronger natural convection of PCM. The present study is helpful for design of PCM/porous medium‐based BTM.
Deciphering Plant Chromatin Regulation via CRISPR/dCas9-Based Epigenome Engineering

CRISPR-based epigenome editing uses dCas9 as a platform to recruit transcription or chromatin regulators at chosen loci. Despite recent and ongoing advances, the full potential of these approaches to studying chromatin functions in vivo remains challenging to exploit. In this review we discuss how recent progress in plants and animals provides new routes to investigate the function of chromatin regulators and address the complexity of associated regulations that are often interconnected. While efficient transcriptional engineering methodologies have been developed and can be used as tools to alter the chromatin state of a locus, examples of direct manipulation of chromatin regulators remain scarce in plants. These reports also reveal pitfalls and limitations of epigenome engineering approaches that are nevertheless informative as they are often associated with locus- and context-dependent features, which include DNA accessibility, initial chromatin and transcriptional state or cellular dynamics. Strategies implemented in different organisms to overcome and even take advantage of these limitations are highlighted, which will further improve our ability to establish the causality and hierarchy of chromatin dynamics on genome regulation.
The effect of activated carbon and silicon oxycarbide as anode materials on lithium-ion battery

SiOC@C is a lithium-ion battery (LIB) anode candidate that is expected to suppress the high volume expansion of Si by the presence of activated carbon as a buffer layer. Silicon oxycarbide (SiOC) was obtained from phenyl-rich silicone oil through pyrolysis at 900°C with flowing Ar gas. The variation of samples used were 4 and 10wt. % SiOC and a pure carbon sample was also prepared for comparison. SEM images show a porous microstructure with a few chunks of agglomerate present. According to Brunner-Emmet-Teller (BET) test, the largest surface area of 542.738 m 2 /g was obtained at 10wt. %SiOC. Based on the performance test result, the highest discharge capacity of 223.3 mAh/g was obtained at the mentioned prime condition.

Corporate Governance Performance Relationship and the Role of Institutions and Culture: New Evidence from Asian Microfinance Institutions

Purpose: In a globalized world today, Microfinance Institutions (MFIs) are concerned about their corporate governance mechanism to enhance financial and social performance. However, it largely depends on the existing institutional, cultural and economic factors. This paper furthers the debate on the impact of corporate governance on the financial and social performance of Microfinance Institutions (MFIs) in Asian Context. Design/Methodology/Approach: The paper utilizes a panel cross-country data set comprised of 183 MFIs in 18 Asian countries over the period of 2010-2018. For empirical analysis, it applies GMM regression technique to control for the endogeniety issue. Findings: The results show that generally corporate governance mechanism contributes more towards social performance of MFIs than the financial performance and a conducive institutional environment enhances both financial and social performance. However, good cultural and economic values contribute only towards the social performance of MFIs.
Consequence of reinforced SiC particles on microstructural and mechanical properties of AA6061 surface composites by multi-pass FSP

Abstract In this work, multi-pass friction stir processing (FSP) was successfully applied to AA6061 to reinforce SiC nanoparticles producing defect-free processes. It can be inferred that Nano SiC particles were fragmented totally and uniformly distributed in sixth pass FSP. Agglomeration of SiC particles decreases with increases in the number of FSP pass. In the first pass, the SiC powder with lower formability than the base metal was concentrated inside the groove, so their flow was difficult, and most of them remained at the center of the SZ. The amount of SiC in the surface composite was further decimated after the second pass FSP cycle. At the same time, a progressive and substantial fragmentation of SiC particles ensues after the fourth and sixth passes, respectively, due to improving material mixing and dispersion. The tensile strength of AA6061 exhibited 275.7 MPa, and a percentage strain of 10.9. After implementing multi-pass FSP with nanoparticles of SiC on the AA6061, the tensile properties were enhanced simultaneously as the FSP pass increases. The tensile strength of one pass, two passes, four passes, and six passes was observed as 291.8, 307.5, 330.5, and 348 MPa, respectively, caused by strain-free fine grains during dynamic recrystallization mechanism. In contrast, Vickers’s hardness value along the centerline (stir zone) was observed as 101, 119, 125, and 134 HV with 1, 2, 4, and 6 FSP pass, respectively.
The sound of social class: Do music preferences signal status?

In three studies, we explore the subjective construal of associations between music preferences and social class. Two small-scale studies (N = 100, N = 70) and one study involving a large representative sample of the Italian population (N = 1,045) reveal that (a) people hold well-defined stereotypes on how music preferences are linked to social class, (b) that these stereotypes do not map onto actual class differences in music taste, (c) that they operate at both an implicit and explicit level, (d) that they are subject to ingroup bias among those who prefer “low-class” genres, and (e) that they are only weakly affected by streaming habits. Together, these findings shed new light on the psychological processes through which people draw inferences about social class on the basis of cultural expression.
Exploration of an alternative to body mass index to characterize the relationship between height and weight for prediction of metabolic phenotypes and cardiovascular outcomes

Body mass index (BMI) is the most commonly used predictor of weight‐related comorbidities and outcomes. However, the presumed relationship between height and weight intrinsic to BMI may introduce bias with respect to prediction of clinical outcomes. A series of analyses comparing the performance of models representing weight and height as separate interacting variables to models using BMI were performed using Vanderbilt University Medical Center's deidentified electronic health records and landmark methodology.
Satellite inference of water vapor and aerosol-above-cloud combined effect on radiative budget and cloud top processes in the Southeast Atlantic Ocean

Abstract. Aerosols have a direct effect on the Earth's radiative budget and can also affect the cloud development and lifetime. The aerosols above clouds (AAC) are particularly associated with high uncertainties in global climate models. Therefore, it is prerequisite to improve the description and understanding of these situations. During the austral winter, large loadings of biomass burning aerosols originating from fires in the southern African subcontinent are lifted and transported long distances westwards, across the Southeast Atlantic Ocean. The negligible wet scavenging of these absorbing aerosols leads to a near-persistent smoke layer above one of the largest stratocumulus cloud deck on the planet. Therefore, the Southeast Atlantic region is a very important area for studying the impact of above cloud absorbing aerosols, their radiative forcing and their possible effects on clouds. In this study we aim to analyse and quantify the effect of smoke loadings on cloud properties using a synergy of different remote sensing technics from A-Train retrievals (methods based on the passive instruments POLDER and MODIS and the operational method of the spaceborne lidar CALIOP), collocated with ERA-Interim re-analysis meteorological profiles. To analyse the possible mechanisms of AACs effects on cloud properties, we developed a high and low aerosol loading approach, that consists in evaluating the change in radiative quantities (i.e. cloud top cooling, heating rate vertical profiles) and cloud properties with the smoke loading. During this analysis, we account for the variation in the meteorological conditions over our sample area. The results show that the region we focus on is primarily under the energetic influence of absorbing aerosols, leading to a significant positive shortwave direct effect at the top of the atmosphere. For larger loads of AACs, clouds are optically thicker, with an increase in liquid water path of 20 g m−2 and lower cloud top altitudes by 100 m. These results do not contradict the semi-direct effect of above cloud aerosols, explored in previous studies. Furthermore, we observe a strong correlation between the aerosol and the water vapor loadings, which has to be accounted for. A detailed analysis of the heating rates shows that the absorbing aerosols are 90 % responsible for warming the ambient air where they reside, with approximately + 5.7 K/day, while the accompanying water vapour above clouds has a longwave effect of + 4.7 K/day (equivalent to 7 % decrease) on the cloud top cooling. We infer that this decreased cloud top cooling in particular, in addition with the higher humidity above the clouds, might modify the cloud top entrainment rate and its effect, leading to thicker clouds. Therefore, smoke (the combination of aerosol and water vapor) events would have the potential to modify and probably reinforce the underlaying cloud cover.
The bioactivity assessment of silver-doped phosphocalcic glasses

The addition of silver ions in the structure of materials with medical uses is a relatively recent technique for orthopedic and maxillofacial reconstruction and aims to reduce the risk of bacterial contamination in the implant. In this paper are presented experimental results for two phosphocalcic glasses from SiO2-CaO-P2O5 system. One of these compositions synthesized by the sol-gel method has been doped with silver. The unsoaked samples show specific spectra of the amorphous structures corresponding to glasses, such as calcium phosphates and calcium silicates. The only crystalline formations present in the glass doped silver structure was metallic silver, highlighted by the peaks at 37.9 2θ and 44.2 2θ, which gives of this composition as being part of glass-metal composite materials [1]. After soaking in simulated body fluid (SBF), both compositions exhibit bioactivity, formation of hydroxyapatite (HAp) on the surface of the glasses, after the first 3 days, with an apparent maximum after 14 days. The silver doped sample has an increase in the number of HAp peaks and after 21 days of immersion, which confirms the assumption that the presence of silver ions increases the effect the bioactivity of the glasses [2]. These results are also confirmed by FTIR and SEM analysis.
Hear no evil? investigating relationships between mindfulness and moral disengagement at work

ABSTRACT To date, over forty-seven studies have examined the antecedents and outcomes of Moral Disengagement (MD) mechanisms used to rationalize unethical behavior. However, none have examined its relationship with mindful awareness, either as a trait or set of everyday applications. Our study (n = 253) demonstrates that trait mindfulness is negatively correlated with all MD mechanisms. The tendency to apply decentering and relaxation is positively correlated with all MD mechanisms while stopping and reappraisal trend toward positive relationships and savoring shows no correlation. We discuss potential reasons for these disparate relationships and implications for mindfulness-based interventions in the workplace.
All ambient environment‐based perovskite film fabrication for photovoltaic applications

Low‐temperature solution process‐able perovskite solar cells are highly desirable for future photovoltaics. Chemical root was utilized to synthesize and optimize mixed halide‐based MAPbIBr2 light absorber perovskites on electron transport layer of TiO2 nanoparticles in ambient atmosphere. For the first time all synthesis work was performed in an ambient environment and observe material behavioral characteristics. To accurately control the film morphology, one‐step deposition technique was applied to investigate material's optoelectronic behavior. The role of the perovskite structure, physical, and optical properties in planner device architecture was studied through ultraviolet visible, X‐ray diffraction, X‐ray photoelectron spectroscopy, and scanning electron microscope characterization techniques to confirm a band gap of 1.76 eV with cubic crystalline structure having a particle size of 12.5–13.0 nm, which is highly suitable for perovskite solar cells.

Design insights into RF/analog and linearity/distortion of spacer engineered multi‐fin SOI FET for terahertz applications

Multi‐fin devices are the most reliable option for terahertz (THz) frequency applications at nano‐regime. In this work impact of spacer engineering on multi‐fin SOI FET performance is evaluated by invoking single low‐k (Air), high‐k (Si3N4, HfO2), and hybrid dual‐k (Air + Si3N4) spacer in the underlap section at nano‐regime. The simulation study reveals that the high‐k (HfO2) spacer gives a higher switching ratio (ION/IOFF) in the order of ~107, subthreshold swing (SS) = 72 mV/dec, drain induced barrier lowering (DIBL) = 22.14 mV/V and quality factor (Q) = gm /SS = 0.16 μS‐dec/mV. Furthermore, to measure the suitability of the device for high frequency applications various analog/RF parameters are studied. The high‐k (HfO2) spacer dominates DC and analog performance, whereas the low‐k (Air) spacer dominates the RF domain with fT = 1.26 THz, GBW = 0.251 THz, TFP = 29 THz range, and with smaller intrinsic delays. Hybrid dual‐k spacer (Air + Si3N4) outperforms in terms of gain (AV) and output resistance ( Ro ). The Air spacer exhibits lower dynamic power of 2.09 aJ/μm and power consumption of 1.04 aJ/μm. The linearity metrics for multi‐fin SOI FET parameters like gm2 , gm3 , HD1, HD2, THD, and VIP2 are also studied. The Air spacer followed by hybrid spacer outperforms in linearity, and harmonic distortion components and ensures its potential for RF applications at nano‐regime.
Cloud Based Smart City Services for Industrial Internet of Things in Software-Defined Networking

The network session constraints for Industrial Internet of Things (IIoT) applications are different and challenging. These constraints necessitates a high level of reconfigurability, so that the system can assess the impact of an event and adjust the network effectively. Software Defined Networking (SDN) in contrast to existing networks segregates the control and data plane to support network configuration which is programmable with smart cities requirement that shows the highest impact on the system but faces the problem of reliability. To address this issue, the SDN-IIoT based load balancing algorithm is proposed in this article and it is not application specific.Quality of service (QoS) aware architecture i.e., SDN-IIoT load balancing scheme is proposed and it deals with load on the servers. Huge load on the servers, makes them vulnerable to halt the system and hence leads to faults which creates the reliability problem for real time applications. In this article, load is migrated from one server to another server, if load on one server is more than threshold value. Load distribution has made the proposed scheme more reliable than already existing schemes. Further, the topology used for the implementation has been designed using POX controller and the results has been evaluated using Mininet emulator with its support in python programming. Lastly, the performance is evaluated based on the various Quality of Service (QoS) metrics; data transmission, response time and CPU utilization which shows that the proposed algorithm has shown 10% improvement over the existing LBBSRT, Random, Round-robin, Heuristic algorithms.
From Bricks to Clicks: How Digital Heritage Initiatives Create a New Ecosystem for Cultural Heritage and Collective Remembering

Cultural heritage institutions, such as museums, libraries, archives, and historical societies, are increasingly using digital heritage initiatives and social media platforms to connect and interact with their heritage communities. This creates a new memory ecosystem whereby heritage communities are invited to contribute, participate with, and share more of what they are interested in collectively remembering, rather than simply accepting the authoritative narratives of heritage institutions, which raises questions about what this means for cultural heritage writ large and whose versions of the past these heritage communities will hold onto as their digital inheritance. The primary contributions of this article are to provide both an extended view of the issue by building on several qualitative studies involving in-depth interviews and digital observations with eight cultural heritage communities over a five-year period and to better understand how their digital heritage initiatives are creating a new ecosystem for cultural heritage and collective remembering.
