This paper utilizes an enhanced gravity model to estimate the effect of lagged immigration waves on Canadian imports and exports, by province. Empirically, this model was tested using Canadian data on import and export flows to the top 40 countries of origin for immigrants to Canada based upon the composition of the most recent wave of immigrants. The results are consistent with previous studie...

Super Mario Galaxy has been almost universally lauded as an enchanting, almost magical game, but what meaning is there to be found within the text? What does the entire experience actually represent and communicate to the player on the whole? With many now wondering what more could possibly be done to advance the classic 3D platformer, this paper aims to examine in depth what transforms Super M...

In this paper, we investigate and analyze the cosmological dynamics of the universe, with an effect of modified f(R) gravity emerging at cosmological scale. We choose the Einstein frame as a physical frame. We consider phase portraits of the universe at the late time from modified f(R) gravity model. This result gives our universe an acceleration phase expansion without introducing existence of...

A gravity model, frequently used to explain trade patterns, is used to explain stock market correlations. The main result of the trade literature is that geography matters for goods markets. Physical location and trading costs should be less of an issue in asset markets. However we find that geographical variables still matter when examining equity market linkages. In particular, the number of ...

We study gravity localization in the context of a six-dimensional gravity model coupled with complex scalar fields. With a supergravity-motivated scalar potential, we show that the domain wall junction solutions localize a four-dimensional massless graviton under an assumption on the wall profile. We find that unlike the global supersymmetric model, contributions to the junction tension cancel ...

I review recent work toward constructing, via five-dimensional holographic duals, fourdimensional theories in which spin-2 states (gravitons) are emergent. The basic idea is to extend to gravity model-building the applications of holographic duality to phenomenology construction.

Picture a small open economy in the North Atlantic Ocean, highly dependent on trade with the EU and NAFTA. How important are these trading blocs to the country’s exports? How important is the country’s location and size, and how do these affect the export sectors? A unique version of the gravity model is applied here using an inverse hyperbolic sine function. Typically, the export volume is sig...
