The balanced tensor product of module categories

The balanced tensor product M (x)_A N of two modules over an algebra A is the vector space corepresenting A-balanced bilinear maps out of the product M x N. The balanced tensor product M [x]_C N of two module categories over a monoidal linear category C is the linear category corepresenting C-balanced right-exact bilinear functors out of the product category M x N. We show that the balanced tensor product can be realized as a category of bimodule objects in C, provided the monoidal linear category is finite and rigid.Comment: 19 pages; v3 is author-final versio

Modular categories as representations of the 3-dimensional bordism 2-category

We show that once-extended anomalous 3-dimensional topological quantum field theories valued in the 2-category of k-linear categories are in canonical bijection with modular tensor categories equipped with a square root of the global dimension in each factor.Comment: 71 page

The High Speed Balancing Game: How Software Companies Cope with Internet Speed

This paper compares and contrasts the practices in developing application software for the Internet in 2000 and 2002. We identify key organizational and technical factors that facilitated or impeded implementation of Internet applications. The identification is done through a grounded theory analysis of data collected from ten companies. A comparison of the 2000 and 2002 data shows how major factors, such as market environment and lack of experience emerged to change the software process and the attitude towar

The Migration of Elites in a Borderless World: Citizenship as an Incentive for Professionals and Managers?

Der Artikel geht der Frage nach, inwiefern die geöffneten Türen für die Immigration Hochqualifizierter in den OECD-Ländern tatsächlich zu einer verstärkten Migrationsbewegung führen. Die Analyse von Daten zu Eliten- und Hochqualifiziertenmigration in Ostasien, Europa und den USA führt zu dem Ergebnis, dass diese dem Muster einer „brain circulation“ folgt und die Staatsbürgerrechte dabei keine entscheidende Rolle spielen

BMW – Mastering the Crises with “New Efficiency?”

Purpose Make a contribution on company business models and typical reactions to economic crises. Design/methodology/approach Media-analysis-based case study. Findings Crisis is handled through drawing on a strategy deriving from the typical features of the company; through the crisis these features are even intensified. Research limitations/implications Multinational companies are complex and only transparent to a small degree; the empirical data therefore rests on a database with articles. Social implications Social implications can be seen at the BMW as a functioning example for social partnership as a form of economic embeddedness at the societal level

Extended 3-dimensional bordism as the theory of modular objects

A modular object in a symmetric monoidal bicategory is a Frobenius algebra object whose product and coproduct are biadjoint, equipped with a braided structure and a compatible twist, satisfying rigidity, ribbon, pivotality, and modularity conditions. We prove that the oriented 3-dimensional bordism bicategory of 1-, 2-, and 3-manifolds is the free symmetric monoidal bicategory on a single anomaly-free modular object.Comment: 64 page

Exploratory Analysis of Nutritional Quality and Metrics of Snack Consumption among Nepali Children during the Complementary Feeding Period.

The World Health Organization recommends feeding snacks between meals to young children. This study explored nutritional quality of snacks consumed between meals and consumption metrics (% total energy intakes (%TEI) and amount of kcal from snacks) to understand correlations with dietary outcomes (total energy intakes and dietary adequacy) and body-mass-index-for-age z-scores (BMIZ). Data used were 24-h dietary recalls and anthropometric measurements among a representative sample (n = 679) of one-year-olds in Nepal. Nepali meal patterns for young children were identified through formative research and all foods/beverages consumed outside of meals were categorized as snacks. A nutrient profiling model was used to categorize snacks as healthy or unhealthy, based on positive and negative nutrient content. Snacks consumed between meals provided half of all energy consumed, and were associated with increased energy and nutrient intakes. The positive effect of snacks between meals on dietary adequacy was greater when these snacks were healthy, while increasing %TEI from unhealthy snacks consumed between meals was negatively associated with dietary adequacy. Consumption of snacks between meals was not associated with mean BMIZ among the children. These findings indicate that the provision of and nutritional quality of snacks are important considerations to communicate to caregivers. Discouragement of unhealthy, nutrient-poor snacks is critical for complementary feeding dietary guidelines in contexts experiencing nutrition transition
