How Companies Respond to Environmental Challenges
No full textUsing twenty scholarly articles provided by Professor Jinsun Bae, information will be extracted using a literature review form which will aid in Jinsun’s larger project. Her project examines corporate responses to labor and environmental issues as reported in journal articles of the past twenty years across various social science disciplines. My literature reviews aim to answer the following question in recent studies published between 2018 and 2023: How do companies respond to environmental challenges in global supply chains?
The findings were that companies are encountering a range of environmental issues. Every industry that was analyzed encountered some sort of environmental issue. Companies adopted several strategies to deal with these environmental challenges, including green supply chain management, partnering with NGOs such as research groups and universities, waste management and recycling, and the adoption of sustainable or alternative materials during the production process
Cross-border Dependencies Among Critical Infrastrucures: Econometric Analysis of Canada-U.S. Vulnerabilities
No full textThis paper explores the application of econometric input-output (I-O) modeling as a method for assessing cross-border critical infrastructure interdependencies (CII), with a focus on Canadian and U.S. sectors. Current Canadian policy frameworks lack quantitative tools and detailed industry-level definitions needed to assess CII risks rigorously. By integrating I-O data from Statistics Canada and the U.S. Bureau of Economic Analysis, the study identifies economic vulnerabilities that span national boundaries, revealing how disruptions—such as to Canadian energy exports or U.S. digital services—can produce cascading impacts across multiple infrastructure sectors. Through a series of sectoral visualizations, the paper demonstrates how round-trip interdependencies and feedback loops amplify infrastructure risks, and how econometric analysis can support more empirical, standardized, and defensible risk assessments. Implications include the potential for better-targeted emergency preparedness strategies, improved public safety outcomes, and more effective cross-border resilience investments. While limitations remain—particularly regarding time-to-impact, substitution effects, and socio-environmental dimensions—the findings underscore the urgent need for quantitative, system-wide approaches to national and international CI risk governance. Recommendations are provided for policymakers, private sector risk managers, national security assessors, and emergency management professionals to integrate I-O modeling into practice
Chromatic k-nearest neighbor queries
No full textLet be a set of colored points in . We develop efficient data structures that store and can answer chromatic -nearest neighbor (-NN) queries. Such a query consists of a query point and a number , and asks for the color that appears most frequently among the points in closest to . Answering such queries efficiently is the key to obtain fast -NN classifiers. Our main aim is to obtain query times that are independent of while using near-linear space.
We show that this is possible using a combination of two data structures. The first data structure allow us to compute a region containing exactly the -nearest neighbors of a query point , and the second data structure can then report the most frequent color in such a region. This leads to linear-space data structures with query times of for points in , and with query times varying between and , depending on the distance measure used, for points in . Since these query times are still fairly large we also consider approximations. If we are allowed to report a color that appears at least times, where is the frequency of the most frequent color, we obtain a query time of in and expected query times ranging between and in using near-linear space (ignoring polylogarithmic factors). All of our data structures are for the pointer-machine model

"Genius! Don\u27t Remember the Product but Certainly Remember the Advert" Being a Marketing Historian and the History of the Advertising Trust, UK
No full textThe idea of the archive is under challenge, to be replaced by the ‘archival multiverse’ where the definition of what is valued in society goes beyond the domain of the official. For Stuart Hall, ‘Archives are not inert historical collections’ but ‘always stand in an active, dialogic, relation to the questions which the present puts to the past” (S. Hall, ‘Constituting an Archive’, Third Text 15 (2001), 92).Plus ça change?As advertising and marketing historians, we are never alone: peering over our shoulders are the masses to whom advertising originally spoke, who “understand” what is presented and can readily tell you what it all means.This paper reflects on what it is to be a marketing historian, and what it is to be the world’s largest brand communications archive. Insights are offered to equip the academic researcher, and a critique presented of what HAT is and what it does.
