De-N-Acetyl Gangliosides: Do they Exist? If So, How Are They Made? What Do They Do?

Universal Grammar and Chaos/Complexity Theory: Where Do They Meet And Where Do They Cross?

  Abstract The present study begins by sketching "Chaos/Complexity Theory" (C/CT) and its applica-tion to the nature of language and language acquisition. Then, the theory of "Universal Grammar" (UG) is explicated with an eye to C/CT. Firstly, it is revealed that CCT may or may not be allied with a theory of language acquisition that takes UG as the initial state of language acquisition for ...

Osteoclasts: what do they do and how do they do it?

As Americans live longer, degenerative skeletal diseases, such as osteoporosis, become increasingly prevalent. Regardless of cause, osteoporosis reflects a relative enhancement of osteoclast activity. Thus, this unique bone resorptive cell is a prominent therapeutic target. A number of key observations provide insights into the mechanisms by which precursors commit to the osteoclast phenotype a...

Chasing After ”Good Jobs” Do They Exist and Does it Matter if They Do?∗

∗This paper was presented as the Innis Lecture at the 2015 Canadian Economics Association Annual Meeting at York University, Toronto. Parts of this paper are based on joint work with Paul Beaudry and Benjamin Sand. I owe them both a huge debt for all that I have learned from them. I am grateful to Paul Beaudry, Kelly Foley, Andrew Green, Craig Riddell and Benjamin Sand for insightful comments o...

Primordial Black Holes: Do They Exist and Are They Useful?

Recent developments in the study of primordial black holes (PBHs) are reviewed, with particular emphasis on their formation and evaporation. It is still not clear whether PBHs formed but, if they did, they could provide a unique probe of the early Universe, gravitational collapse, high energy physics and quantum gravity. Indeed their study may place interesting constraints on the physics releva...
