Sir, Ethanol, the intoxicant that has plagued civilization down the ages, is metabolized into acetaldehyde by the enzyme alcohol dehydro-genase. In this connection, a medical student recently posed a humorous but interesting question : "Ethanol does not occur naturally in the body; so, why did Nature provide us with alcohol dehydrogenase unless she meant us to drink?" A diligent search through ...

There is a fairly extensive literature on letter-place algebras, but mostly for the edification of those working in algebraic combinatorics (see, for instance, [15, 16, 18, 20]). I don’t think that letter-place algebras have had much play yet in commutative and homological algebra, so I thought I’d talk about them here and perhaps arouse a bit of interest in that subject. I was introduced to th...

Scholarly reputations that for a time seem unimpeachable now shrink or evaporate so speedily that ‘‘intergenerational’’ perceptions of whom to read will soon be measured in months rather than decades. As some theorists have begun to explain (e.g., Hassan 2012; Rosa 2013), to remain hip in any single intellectual or artistic field becomes ever more taxing, more and more breathless, with returns ...

Californian almond farmers do not need native bees. The logic of the bee market decrees it. Opportunity costs of setting aside land to promote the diversity of wild bees are higher than importing pollinators from a bee factory in some far-flung, distant metropolis (Ghazoul 2007). Conservationists cannot complain about such a perverse situation because they established the economic framework in ...

Global information infrastructures can offer tremendous opportunities for small and medium enterprises to do global business electronically. But communication networks alone are not sufficient to enable international electronic trade. Parties have to know about each others' "way of doing business" before they can start exchanging data electronically; they have to agree upon the trade procedure ...

The design and delivery of effective digitization for formative and summative assessments that are suitable for computer-based exam delivery remains an open problem across engineering curricula. Engineering-specific exam digitization challenges include the need to adequately evaluate design skills, solution structure, intermediate work, creativity, conceptual understanding, and in many cases, r...

In three samples containing Buddhist and Christian participants from several nations, participants of both religions manifested a generally similar relationship between religiosity and intolerance. In all three samples, devotional religiosity (e.g. prayer frequency, faith devotion), was strongly correlated with coalitional religiosity (e.g. organized religious attendance, fundamentalism). Yet d...

Emerging technologies are facilitating the production of revised and novel forms of “digital being” combined frames of meaning, experience, and desired notions of performativity that change what and who we are. A number of theoretical perspectives (e.g. Agential Realism and Sociomateriality) have emerged that seek to address this new reality but have struggled to grapple with the relationship b...
