Previous research on corporate social responsibility (CSR) investigates customers' perceptions; however, employees' view of CSR remains largely unexplored. Corporate culture and its capabilities ...become resources for the competitive advantage and employee perceptions of CSR activities play an important role in employee attachment to their company as well as corporate performance. Therefore, this study examines how the perceived cultural fit and CSR capability influence employee attachment and performance through the mediating variables of their perceptions of CSR activities. The empirical findings suggest that perceived cultural fit and CSR capability significantly affect CSR perception and, consequently, employee attachment and performance. The results offer important implications for marketing theory and practice.
Abstract
The electrosynthesis of formate from CO
2
can mitigate environmental issues while providing an economically valuable product. Although stannic oxide is a good catalytic material for formate ...production, a metallic phase is formed under high reduction overpotentials, reducing its activity. Here, using a fluorine-doped tin oxide catalyst, a high Faradaic efficiency for formate (95% at 100 mA cm
−2
) and a maximum partial current density of 330 mA cm
−2
(at 400 mA cm
−2
) is achieved for the electroreduction of CO
2
. Furthermore, the formate selectivity (≈90%) is nearly constant over 7 days of operation at a current density of 100 mA cm
−2
.
In-situ/operando
spectroscopies reveal that the fluorine dopant plays a critical role in maintaining the high oxidation state of Sn, leading to enhanced durability at high current densities. First-principle calculation also suggests that the fluorine-doped tin oxide surface could provide a thermodynamically stable environment to form HCOO* intermediate than tin oxide surface. These findings suggest a simple and efficient approach for designing active and durable electrocatalysts for the electrosynthesis of formate from CO

Mechanical properties of biological systems provide useful information about the biochemical status of cells and tissues. Here, an artificial tactile neuron enabling spiking representation of ...stiffness and spiking neural network (SNN)‐based learning for disease diagnosis is reported. An artificial spiking tactile neuron based on an ovonic threshold switch serving as an artificial soma and a piezoresistive sensor as an artificial mechanoreceptor is developed and shown to encode the elastic stiffness of pressed materials into spike frequency evolution patterns. SNN‐based learning of ultrasound elastography images ed by spike frequency evolution rate enables the classification of malignancy status of breast tumors with a recognition accuracy up to 95.8%. The stiffness‐encoding artificial tactile neuron and learning of spiking‐represented stiffness patterns hold a great promise for the identification and classification of tumors for disease diagnosis and robot‐assisted surgery with low power consumption, low latency, and yet high accuracy.

Abstract In recent research on psychologically controlling parenting, debate has arisen about the cross-cultural relevance of this construct, with some scholars arguing that the developmental ...outcomes of psychological control are culture-bound and others arguing that the detrimental effects of psychological control generalize across cultures. This study aimed to add to this debate by examining the relevance of a distinction between two domain-specific expressions of psychological control (i.e., dependency-oriented and achievement-oriented) in Belgian ( N = 290) and South-Korean ( N = 321) adolescents. Multi-group path analyses showed that associations between the domains of psychological control, depressive personality, and depressive symptoms were similar between the two samples. Overall, the findings are in line with the notion that the effects of psychological control generalize across culture.
•Perceived psychosocial–superstitious risk was named and proposed for the first time as a variable representing the characteristics of Chinese consumers toward secondhand luxury consumption to ...explain the unique character of Chinese consumers (i.e., rampant counterfeiting of luxury goods and strong superstition and stereotypes about secondhand goods).•Perceived functional, financial, sales-source, physical, and psychosocial–superstitious risks have been systematically conceptualized to explain why Chinese consumers are reluctant to purchase secondhand luxury goods.•Perceived risks affect Chinese consumers’ purchase intentions by negatively affecting their perceived value.•Self-regulatory focus significantly moderates the relationship between perceived risks and perceived value. A promotion focus can weaken the negative influence of perceived risk on perceived value, whereas a prevention focus can strengthen it.•During the COVID-19 pandemic, the impacts of perceived risks on perceived value have changed. Before the pandemic, perceived physical and psychosocial–superstitious risks were the most important reasons why Chinese consumers were reluctant to purchase secondhand luxury goods. However, given the outbreak of the pandemic, the effects of perceived functional and financial risks emerged as the most critical reasons for nonpurchase.
The purchasing environment for Chinese consumers is rife with rampant counterfeit luxury goods and strong superstitions and stereotypes about secondhand goods. Therefore, this study conceptualized five dimensions of perceived risk (perceived functional, financial, sales-source, physical, and psychosocial–superstitious) to explain Chinese consumers’ reluctance to purchase secondhand luxury goods (SLGs). Due to the sudden onset of the COVID-19 pandemic, this research was divided into two studies: before and during the outbreak. The pre-outbreak results show that, except for financial risk, all perceived risks significantly negatively affected the perceived value of SLGs. Conversely, the second study revealed that all five categories had significant negative effects. Additionally, both studies showed that perceived value positively affected SLG purchase intention, while self-regulatory focus (prevention focus against promotion focus) had a significant moderating effect. This research has several significant theoretical and practical implications for establishing more effective marketing strategies for the sustainable development of SLG markets.
Small RNA‐mediated gene silencing (RNA silencing) has emerged as a major regulatory pathway in eukaryotes. Identification of the key factors involved in this pathway has been a subject of rigorous ...investigation in recent years. In humans, small RNAs are generated by Dicer and assembled into the effector complex known as RNA‐induced silencing complex (RISC) by multiple factors including hAgo2, the mRNA‐targeting endonuclease, and TRBP (HIV‐1 TAR RNA‐binding protein), a dsRNA‐binding protein that interacts with both Dicer and hAgo2. Here we describe an additional dsRNA‐binding protein known as PACT, which is significant in RNA silencing. PACT is associated with an ∼500 kDa complex that contains Dicer, hAgo2, and TRBP. The interaction with Dicer involves the third dsRNA‐binding domain (dsRBD) of PACT and the N‐terminal region of Dicer containing the helicase motif. Like TRBP, PACT is not required for the pre‐microRNA (miRNA) cleavage reaction step. However, the depletion of PACT strongly affects the accumulation of mature miRNA in vivo and moderately reduces the efficiency of small interfering RNA‐induced RNA interference. Our study indicates that, unlike other RNase III type proteins, human Dicer may employ two different dsRBD‐containing proteins that facilitate RISC assembly.
Sustainability and environmental initiatives continue to receive an increasing amount of attention, both within the corporate, consumer, and individual domains of behavior. As individuals act on ...their environmental interests, or lack thereof, it is incumbent upon researchers to continue delineating factors that may influence the commitment and behaviors that take place. To this end, this research effort capitalizes on the long history of cultural orientation, examining the influence of individualism and collectivism as antecedents to perceived consumer effectiveness (PCE), environmental attitude, and environmental commitment. Utilizing cross-cultural data drawn from South Korea and the United States, the empirical results provide support for horizontal collectivism and vertical individualism as important influencers of perceived consumer effectiveness. In turn, PCE positively affects environmental attitude which results in pro-environmental commitment manifested in specific behavioral intentions.
Ribosomal protein S6 (RPS6) is a component of the 40S small ribosomal subunit and participates in the control of mRNA translation. Additionally, phospho (p)-RPS6 has been recognized as a surrogate ...marker for the activated PI3K/AKT/mTORC1 pathway, which occurs in many cancer types. However, downstream mechanisms regulated by RPS6 or p-RPS remains elusive, and the therapeutic implication of RPS6 is underappreciated despite an approximately half a century history of research on this protein. In addition, substantial evidence from RPS6 knockdown experiments suggests the potential role of RPS6 in maintaining cancer cell proliferation. This motivates us to investigate the current knowledge of RPS6 functions in cancer. In this review article, we reviewed the current information about the transcriptional regulation, upstream regulators, and extra-ribosomal roles of RPS6, with a focus on its involvement in cancer. We also discussed the therapeutic potential of RPS6 in cancer.
Mid-infrared wavelengths are called the molecular fingerprint region because it contains the fundamental vibrational modes inherent to the substances of interest. Since the mid-infrared spectrum can ...provide non-destructive identification and quantitative analysis of unknown substances, miniaturized mid-infrared spectrometers for on-site diagnosis have attained great concern. Filter-array based on-chip spectrometer has been regarded as a promising alternative. In this study, we explore a way of applying a pillar-type plasmonic nanodiscs array, which is advantageous not only for excellent tunability of resonance wavelength but also for 2-dimensional integration through a single layer process, to the multispectral filter array for the on-chip spectrometer. We theoretically and experimentally investigated the optical properties of multi-periodic triangular lattices of metal nanodiscs array that act as stopband filters in the mid-infrared region. Soft-mold reverse nanoimprint lithography with a subsequent lift-off process was employed to fabricate the multispectral filter array and its filter function was successfully extracted using a Fourier transform infrared microscope. With the measured filter function, we tested the feasibility of target spectrum reconstruction using a Tikhonov regularization method for an ill-posed linear problem and evaluated its applicability to the infrared spectroscopic sensor that monitors an oil condition. These results not only verify that the multispectral filter array composed of stopband filters based on the metal nanodiscs array when combined with the spectrum reconstruction technique, has great potential for use to a miniaturized mid-infrared on-chip spectrometer, but also provide effective guidance for the filter design.
There is a rapidly growing demand for highly efficient ultraviolet (UV) light sources for a wide variety of applications. In particular, state-of-the-art AlGaN deep UV light-emitting diodes (DUV ...LEDs) exhibit inadequately low external quantum efficiencies (EQEs). The low efficiencies are attributed to the inherent material properties of high-Al-content AlGaN including strained epitaxial layers, low carrier concentrations, and strong transverse magnetic (TM)-polarized light emission. Extensive efforts have been made to tackle these challenging issues and technological developments have been achieved and enabled the fabrication of reasonable EQE LEDs. In this review, recent advances in the growth of high-quality AlGaN epitaxial layers, transparent and reflective ohmic contacts, and light extraction for AlGaN-based UV LEDs are reviewed.
