Multiple scattering, radiative transfer, and parameter regimes

We have established the radiative transfer regime in a four-parameter space spanned by amplitude and scale of fluctuations, convergence rate, and spatial range. The derivation of radiative transfer equations from wave equations offers a better understanding of the underlying physics in radiative transfer theory. One approach is based on tools borrowed from quantum field theory (QFT) and employs the Dyson and Bethe–Salpeter equations as the foundation. This has allowed us to investigate the small scale fluctuation regime, kl = O ( ε ) . We also investigated this regime using the scale-separated asymptotics approach and found that the conditions on the parameters are the same as in the QFT approach if the convergence rate of the Dyson series is O ( ε 2 ) . Furthermore, we found that there is a multitude of regimes where radiative transfer manifests. We hence infer that for a fixed spatial range, increase in the scale size of fluctuations leads to decrease in the upper bound of variance of permittivity fluctuations along with diminished convergence rate of the Wigner series. Also, for a fixed scale size and convergence rate, the spatial range where radiative transport manifests decreases with increase in strength of fluctuations.

The city from its margins: rethinking urban governance through the everyday lives of migrant women in Johannesburg

Drawing on ethnographic data, this article explores migrant women’s relationships and encounters with the state in South Africa’s largest city, Johannesburg. Focusing on the experiences of people in this marginal location, the article re-examines the notion of ‘urban governance’, which is often understood as the realm of formal urban institutions in which the state asserts its authority and regulatory powers. Through the everyday lives of migrant women we see that local urban practices are not simply shaped by the formalism of state rules and regulations, or their informal illegal counterparts. The way migrant women navigate the city, trade on the streets, and interact with the state and other urban actors illustrates that governance is co-constructed by a multitude of regimes, legal and illegal, visible and invisible. Indeed, women’s lives collapse the dichotomy of the official and unofficial, governed and ungoverned city, in ways that allow us to rethink how we conceptualise the city.

Tryst with Delaware Corporate Takeover Law

The Delaware Takeover law is a multitude of regimes that govern the conduct of Board of Directors in a business acquisition setting. During an acquisition there are numerous risks that need to be addressed including business risks, financial risks, commercial litigation, tax, intellectual property infringement, and antitrust issues. When a board is confronted with a proposed transaction, it has the obligation to determine whether the offer is in the best interests of the corporation and its shareholders. Absent certain limited set of circumstances when it needs to emphasize on short-term merits of the transaction, the board must focus at the long-term strategy of the combined company. This paper discusses the bidding war between Verizon and Qwest Communications over the acquisition of MCI, Inc. By invoking the legal mandate governing the Delware Corporate takeover law, the paper attempts to highlight such nuances of an acquisition setting.
