For a category $${\textsf{B}}$$ with finite products, we first characterize pseudofunctors from to $$\mathbb {C}\textsf{at}$$ whose associated opfibration is Cartesian monoidal. Among those, then the ones which extend internal groups 2-groups. If additive, this case precisely when has groupoidal fibres.

Today communication has been revolutionized with email and other online communication systems. However, some computer users have abused the technology used to drive these communications, by sending out thousands and thousands of spam emails with little or no purpose other than to increase traffic or decrease bandwidth. With the electronic mail emerging

Dying cells actively attract professional phagocytes by sending out soluble 'find-me' signals. The characterization and identification of the corresponding molecular entities have revealed that 'find-me' signals come in different flavors, including peptides, proteins, lipids and complex structures, such as apoptotic microblebs. With the very recent report by Elliott et al., nucleotides as a nov...

Diabetes-STAR is a disease management program integrated with an online patient portal. Of 331 patients enrolled in a randomized trial, we interviewed 37 users about benefits, barriers and recommendations for program improvements. User preferences included 1) addressing differences in types of users, 2) sending out alerts when new information is available, and 3) providing more oversight of use...

Private transfers between households in developing countries have been extensively studied and shown to be economically important for these households. We argue that migration and remittances have the potential to modify the prevalent transfer behaviour in migrant-sending communities. A priori, it is indeterminate whether migration and remittances strengthen or weaken the degree of private tran...

An electronic commerce marketing channel is fully mediated by information technology, stripping away much 17 of a product’s physical informational cues, and creating information asymmetries (i.e., limited information). 18 These asymmetries may impede consumers’ ability to effectively assess certain types of products, thus creating 19 challenges for online sellers. Signaling theory provides a fr...

The economies of a number of Pacific island countries have become increasingly dependent on the remittance of migrants. A series of recent International Labour Office research projects in the South Pacific focused on two countries—Tonga and Western Samoa (Brown 1994). Recommendations from these insights serve as a basis for a policy dialogue with the financial authorities of Pacific island coun...
