Institutionalizing diversity and inclusion engaged marketing (DIEM) for multicultural marketplace wellbeing
Within an institutional theory framework, this paper identifies three interconnected fields of the marketing institution – research, education, and practice – that contribute to advancing the diversity and inclusion discourse in promoting multicultural marketplace wellbeing. Conducting three studies, one in each field and across contexts in three continents, we identify barriers that inhibit effective implementation of diversity and inclusion initiatives in today’s multicultural marketplaces. These barriers exist within and across fields and pertain to cultural-cognitive (shared meanings), normative (normative factors), and regulatory (rules and systems) pillars supporting the existence or transformation of institutions. From our research findings, we provide specific guidance for institutional work within marketing’s fields and policy developments needed to advance diversity and inclusion engaged marketing (DIEM) for enhancing multicultural marketplace wellbeing
Self-assembly of supramolecular triarylamine nanowires in mesoporous silica and biocompatible electrodes thereof
Biocompatible silica-based mesoporous materials, which present high surface areas combined with uniform distribution of nanopores, can be organized in functional nanopatterns for a number of applications. However, silica is by essence an electrically insulating material which precludes applications for electro-chemical devices. The formation of hybrid electroactive silica nanostructures is thus expected to be of great interest for the design of biocompatible conducting materials such as bioelectrodes. Here we show that we can grow supramolecular stacks of triarylamine molecules in the confined space of oriented mesopores of a silica nanolayer covering a gold electrode. This addressable bottom-up construction is triggered from solution simply by light irradiation. The resulting self-assembled nanowires act as highly conducting electronic pathways crossing the silica layer. They allow very efficient charge transfer from the redox species in solution to the gold surface. We demonstrate the potential of these hybrid constitutional materials by implementing them as biocathodes and by measuring laccase activity that reduces dioxygen to produce water
Graphite Furnace Atomic Absorption Elemental Analysis of Ecstasy Tablets
Abstract: Six metals (Cu, Mg, Ba, Ni, Cr, Pb) were determined in two separate batches of seized ecstasy
tablets by graphite furnace atomic absorption spectroscopy (GFAAS) following digestion with nitric
acid and hydrogen peroxide. Large intra-batch variations were found as expected for tablets produced
in clandestine laboratories. For example, nickel in batch 1 was present in the range 0.47-13.1 ppm and
in batch 2 in the range 0.35-9.06 ppm. Although batch 1 had significantly higher MDMA content than
batch 2, barium was the only element which discriminated between the two ecstasy seizures (batch 1:
0.19-0.66 ppm, batch 2: 3.77-5.47 ppm)
Special Session: Cultural Identity and Adaptation in Global Marketplaces: Methodological, Conceptual, and Empirical Insights: An Abstract
A multi-contextual lens on racism and discrimination in the multicultural marketplace
This article highlights the generative properties of context for consumer experiences of racism and discrimination. Drawing from conceptualizations of context in social anthropology and human geography, it develops a framework to systematically catalogue intersections of various micro- and macro-social contexts that configure within and across marketplace geographies and inform racism and discrimination. The framework is
applied to an integrative review of studies on marketplace racism and discrimination. The review illuminates that: 1) application of intersectional perspectives varies significantly
across cultural difference dimensions; 2) knowledge is clustered within specific micro-social context expressions of cultural difference dimensions; 3) studies intersecting micro- and macro-social expressions commonly reveal underexplored discrimination instances; and 4) knowledge on macro-social contextual forces significantly lacks non-western perspectives. Drawing on the review findings, a list of areas of advancement for future scholarship is presented, along with recommendations for marketing practitioners acting towards identifying, understanding, and counteracting racism and discrimination
Utilisation des simulations informatiques et de la réalité virtuelle pour comprendre, concevoir et optimiser les canaux d'eau artificiels
International audienceIn biology, metabolite transport across cell membranes occurs through natural channels and pores. Artificial ion-channel architectures represent potential mimics of natural ionic conduction. Many such systems were produced leading to a remarkable set of alternative artificial ion-channels. Far less advances were achieved in the area of synthetic biomimetic water channels, even though they could improve our understanding of the natural function of protein channels and may provide new strategies to generate highly selective, advanced water purification systems. Most realizations have used the selectivity components of natural protein channels embedded in artificial systems. Such biomolecules provide building blocks to constitute highly selective membrane-spanning water transport architec-tures. The simplification of such compounds, while preserving the high conduction activity of natural macromolecules, lead to fully synthetic artificial biomimet-ic channels. These simplified systems offer a particular chance to understand mechanistic and structural behaviors, providing rationales to engineer better artificial water-channels. Here we focus on computer simulations as a tool to complement experiment in understanding the properties of such systems with the aim to rationalize important concepts, design and optimize better compounds. Molecular dynamics simulations combined with advanced visual scrutiny thereof are central to such an approach. Novel technologies such as virtual reality headsets and stere-oscopic large-scale display walls offer immersive collaborative insight into the complex mechanisms underlying artificial water channel function.En biologie, le transport des métabolites à travers les membranes cellulaires se fait par les canaux naturels et les pores. Les architectures artificielles à canaux ioniques représentent des imitations potentielles de la conduction ionique naturelle. Beaucoup de ces systèmes ont été produits, ce qui a conduit à un ensemble remarquable de canaux ioniques artificiels alternatifs. Beaucoup moins d'avancées ont été réalisées dans le domaine des canaux d'eau biomimétiques synthétiques, même si elles pourraient améliorer notre compréhension de la fonction naturelle des canaux protéiques et peuvent fournir de nouvelles stratégies pour générer des systèmes de purification d'eau avancés et hautement sélectifs. La plupart des réalisations ont utilisé les composants de sélectivité des canaux protéiques naturels intégrés dans des systèmes artificiels. Ces biomolécules fournissent des éléments constitutifs pour constituer des architec-tures de transport d'eau à membrane hautement sélective. La simplification de ces composés, tout en préservant l'activité de conduction élevée des macromolécules naturelles, conduit à des canaux biomimétiques artificiels entièrement synthétiques. Ces systèmes simplifiés offrent une chance particulière de comprendre les comportements mécanistiques et structurels, offrant des justifications pour concevoir de meilleurs canaux d'eau artificiels. Ici, nous nous concentrons sur les simulations informatiques en tant qu'outil pour compléter l'expérience dans la compréhension des propriétés de ces systèmes dans le but de rationaliser les concepts importants, de concevoir et d'optimiser de meilleurs composés. Les simulations de dynamique moléculaire combinées à un examen visuel avancé de celles-ci sont au cœur d'une telle approche. De nouvelles technologies telles que des casques de réalité virtuelle et des murs d'affichage à grande échelle stéréoscopiques offrent un aperçu collaboratif immersif des mécanismes complexes qui sous-tendent la fonction de canal d'eau artificiel
