A three-dimensional reactive transport model for sediments, incorporating microniches.
No full textMost reactive transport models have represented sediments as one-dimensional (1-D) systems and have solely considered the development of vertical concentration gradients. However, application of recently developed micro-scale and 2-D measurement techniques have demonstrated more complicated solute structures in some sediments, including discrete localized sites of depleted oxygen, and elevated trace metals and sulphide, referred to as microniches. A model of transport and reaction in sediments, that can simulate the dynamic development of concentration gradients occurring in 3-D, was developed. Its graphical user interface (GUI) allows easy input of user-specified reactions and provides flexible schemes that prioritise their execution. The 3-D capability was demonstrated by quantitative modelling of hypothetical solute behaviour at organic matter microniches covering a range of sizes. Significant effects of microniches on the profiles of oxygen and nitrate are demonstrated. Sulphide is shown to be readily generated in microniches within one centimetre of the sediment surface, provided the diameter of the reactive organic material is greater than one millimetre. These modelling results illustrate the geochemical complexities that arise when processes occur in 3-D and demonstrate the need for such a model. Future use of high-resolution measurement techniques should include the collection of data for relevant major components, such as reactive iron and manganese oxides, to allow full, multi-component modelling of microniche processes

Platform Rules: Multi-Sided Platforms as Regulators
No full textThis paper provides a basic conceptual framework for interpreting non-price instruments used by multi-sided platforms (MSPs) by analogizing MSPs as "private regulators" who regulate access to and interactions around the platform. We present evidence on Facebook, TopCoder, Roppongi Hills and Harvard Business School to document the "regulatory" role played by MSPs. We find MSPs use nuanced combinations of legal, technological, informational and other instruments (including price-setting) to implement desired outcomes. Non-price instruments were very much at the core of MSP strategies.Platforms, regulation, network effects, distributed innovation
Adoption Potentials of Metaverse Omnichannel Retailing and Its Impact on Mass Customization Approaches
No full textWith the emergence of Web3, metaverse and virtual reality technologies, both retailers and brand manufacturers are entering a new era centered on hyperactive and highly engaged consumers. The growth and size of the market allow all ambitious companies to respond innovatively to the challenges of branding, integrated marketing communication, clienteling, retailtainment, and customer experience through virtual co-creation processes within mass customization approaches. The article aims to understand better how to seize current and future opportunities for retailers and implement omnichannel solutions that are avant-garde, personalized, and more relevant to consumers. The objective is to analyze human beings’ readiness to use metaverse channels in the context of omnichannel retailing. We set the ground for understanding if an immersive experience allows the subsequent consumption of specific products: highly visualize to buy better and smarter. Thus, the article illustrates the likelihood that individuals will use the virtual channel for their shopping needs, the factors that may influence this willingness, and what a metaverse environment might look like in the retail industry. The exploratory quantitative study was conducted in July 2022. The final sample of the survey, after quality controls, was composed of 286 participants from different continents. The study shows respondents’ resistance to buying products, especially digital assets, within the metaverse. Familiarity, enthusiasm, and conviction are essential drivers for using the virtual channel. Consumers who appreciate personalized offers and a sense of belonging to a brand show a higher likelihood of purchasing in the metaverse. The findings reveal promising opportunities for building communities and co-creating and customizing products, with furniture and clothing likely having the most significant potential in the metaverse. On the other hand, privacy and security risks are sub-stantial concerns, indicating that there are still many challenges to overcome
La tarification des services publics : financement différent ou taxe supplémentaire? Fascicule 1 : Un contexte favorable
No full textVieillissement de la population, renouvellement des infrastructures, remboursement de la dette : le Québec devra relever des défis majeurs en matière de financement des services publics au cours des prochaines décennies. Au moment où le gouvernement du Québec crée un groupe de travail sur la tarification des services publics, quelle est la place de la tarification par rapport aux impôts dans les revenus totaux de l'État? Le premier fascicule de cette étude réalisée par Gilles N. Larin et Daniel Boudreau, qui s'intitule « La tarification des services publics : financement différent ou taxe supplémentaire? Fascicule 1 : Un contexte favorable », explique que malgré un contrôle serré des dépenses, le financement par la méthode traditionnelle des impôts et des taxes risque de s'avérer insuffisant et inapproprié pour assurer la pérennité des services

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
