Consumer behavior with augmented reality in retail: a review and research agenda

2021

Driven by the rapid technological development and adoption of augmented reality (AR) in retail, academic research has grown rapidly. Our purpose is to understand the reasons why consumers use augmented reality in retail and what outcomes retailers can expect. This study presents a systematic literature review and summarizes the current empirical knowledge on consumer behavior with AR in retail. This topic remains scattered between various literature streams showing that the potential of AR to create value for consumers lays in its ability to generate utilitarian and hedonic value, to improve decision-making, and to enhance personalization of the virtual self. Then, this study warns about ne…

Employee trust repair: A systematic review of 20 years of empirical research and future research directions

2021

Employee trust, and increasingly its absence, is a critical topic for researchers and practitioners interested in social relations in the context of work and organizing. Employee trust repair is particularly important in the current disrupted work environment, due to unpredictable changes such as the Covid-19 pandemic and the uncertainty those bring to our lives. It is not surprising that employee trust is attracting increasing interest among researchers and practitioners alike. In this article, we systematically review and take stock of the research on trust repair conducted in the past two decades to provide comprehensive insights and future research directions for researchers and manager…

Synthesis of yttrium aluminum garnet nanoparticles in confined environment II: Role of the thermal treatment on the composition and microstructural e…

2017

Abstract Nanoparticles of yttrium aluminum garnet (YAG, Y 3 Al 5 O 12 ) have been obtained by thermal treatments, at several temperature in the range 400–950 °C, of the precursors synthetized via co-precipitation in water in oil microemulsion. The obtained nanoparticles have been characterized by means of X-ray Diffraction and Transmission Electron Microscopy coupled with Energy Dispersive X-ray Spectroscopy (EDS) and Select Area Electron Diffraction (SAED). Results show the phase evolution occurring to obtain not aggregated nanoparticles of YAG phase. A possible growth mechanism of YAG nanoparticles is discussed on the basis of observed particle microstructure and morphology. The results i…

Sulfidation Mechanism of Pure and Cu-Doped ZnO Nanoparticles at Moderate Temperature: TEM and In Situ XRD Studies

2012

International audience; Sulfidation mechanism of pure and Cu-doped ZnO nanoparticles (Cu0.03Zn0.97O and Cu0.06Zn0.94O) at 250 and 350 degrees C was studied by transmission electron microscopy (TEM) and in situ synchrotron XRD. For nondoped ZnO, we observed by TEM that partial reaction with H2S is accompanied by the formation of voids at the ZnO/ZnS interface. This phenomenon (known as the Kirkendall effect) confirms that sulfidation of nanosized ZnO by gaseous H2S proceeds via the outward growth of ZnS: Zn2+ and O2- are transferred to the external (ZnS/gas) surface, where zinc is combined with sulfur and oxygen reacts with protons yielding H2O. During sulfidation of Cu-doped ZnO, the caviti…

Improvement of photocatalytic and photoelectrochemical activity of ZnO/TiO2 core/shell system through additional calcination: Insight into the mechan…

2017

Abstract ZnO/TiO2 composites were prepared by sol-gel deposition of TiO2 on ZnO nanorods hydrothermally grown on electrically conductive indium tin oxide substrate (ITO). It has been shown that the ZnO/TiO2 interface plays a key role in enhancement of photodecomposition of methylene blue (MB) used as a model test pollutant, under monochromatic light irradiation (400 nm). The increase of photocatalytic activity was attributed to the shift of absorption edge of ZnO/TiO2 towards visible light in comparison with bare TiO2. Further enhancement of photocatalytic activity of ZnO/TiO2 was achieved through its additional calcination at 450 °C for 3 h. This treatment brings 40% increase in the rate o…

Tertiary Chiral Nanostructures from C‐H∙∙∙F Directed Assembly of Chiroptical Superatoms

2021

Chiral hierarchical structures are universal in nature, whereas quite challenging to mimic in man-made synthesis. We report herein the synthesis and structure of tertiary chiral nanostructures with 100% optical purity. A novel synthetic strategy, using chiral reducing agent, R and S -BINAPCuBH 4 (BINAP is 2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl), is developed to access to atomically precise, intrinsically chiral [Au 7 Ag 6 Cu 2 ( R - or S -BINAP) 3 (SCH 2 Ph) 6 ]SbF 6 nanoclusters in one-pot synthesis. The clusters represent the first tri-metallic superatoms with inherent chirality and fair stability. Both metal distribution (primary) and ligand arrangement (secondary) of the enantiomer…

Autobiographical reading

2010

In my book, I have attempted the elaboration of a system for rereading 20th-century Hungarian autobiographies, by way of putting the emphasis on theoretical considerations. (From the “Death of the Author” to the Resurrection of the Author, Stereotypes in Autobiographical Reading) The major analytical aspects of the Autobiographical Reading focuses on the language based means of the representation of the Self. (Language and Subject, Staging the Self, Inter-Replacing Play of Image and Representation, Relationship between the Narrating and the Narrated Autobiographical Self, Memory and Identity) The choice of this subject matter is justified first of all by the fact that the conditions for the…

"...egy tömegmészárlásról mi értelmes dolgot lehetne elmondani?" : az ábrázolásmód mint történelemkoncepció a holokauszt-irodalomban

2006

Traumaattisista historiallisista tapahtumista kertovissa kaunokirjallisissa teoksissa voidaan nähdä implisiittistä historian kuvausta. Tamás Kisantal lähestyy väitöksessään kaunokirjallisia tekstejä historiallis-filosofisesta näkökulmasta ja soveltaa narratiivisen historianfilosofian metodeja esimerkiksi holokaustiin liittyvän kirjallisuuden tarkastelemiseen. Kisantalin mukaan holokaustin kuvaukseen liittyy eettinen ulottuvuus, joka on yksi tärkeimmistä seikoista historiankuvauksessa. Hän toteaa, että menneisyyttä voi tutkia ainoastaan huomioimalla tämän ulottuvuuden.Kisantal analysoi kaunokirjallisia tekstejä, jotka kuvaavat traumaattisia historiallisia tapahtumia narratiivisen historianfi…
