[Review of] Howard Brotz, ed. African-American Social and Political Thought
African-American Sociol ond Political Thought, originally published in 1966, is back in print-testimony to the durability of the writings it collects. The editor provides a selection of primary works by great African-American thinkers whom he categorizes into four mainstreams: emigrationists, assimilationists, cultural nationalists, and revived political nationalists. The works of such men as Martin Delany, Frederick Douglass, W. E.B. Dubois, and Marcus Garvey, stand alone for their brilliance, but brought together, they provide a panoramic view of the diversity of African-American philosophies for Black advancement
[Review of] Donald W. Jackson. Even the Children of Strangers: Equality under the U.S. Constitution
Can separate but equal really be equal? How do we achieve equality through remedial preferential treatment? Does America\u27s meritocracy dictate inequality? These compelling questions are addressed in Donald Jackson\u27s Even Children of Strangers: Equality Under the U.S. Constitution
External morphology of eyes and Nebenaugen of caridean decapods–ecological and systematic considerations
Most caridean decapods have compound eyes of the reflecting superposition kind, and additionally some possess an accessory eye-like organ of unknown function, also referred to as the nebenauge.We examined 308 caridean genera to assess the general morphology of the eye, rostrum length, eye diameter and the presence or absence and, when present, the diameter of the nebenauge.We have attempted to relate these data to ecological and taxonomic considerations.We consider there to be 6 distinct eye types based on the margin between the eyestalk and cornea. The presence of nebenaugen appears to be generally linked to an active lifestyle, as evidenced by the fact that species that have nebenaugen tend to have larger eyes and are more likely to have a distinct rostrum.We suggest that the inconsistencies in its presence/absence under both systematic and ecological lenses may indicate that when present it has various roles relating to behavioural and physiological rhythms
Linking eye design with host symbiont relationships in pontoniine shrimps (crustacea, decapoda, palaemonidae)
Symbiosis is prevalent in the marine environment with many studies examining the effects of such interactions between host and symbiont. Pontoniine shrimps are a group whose ecology is characterised by symbiotic interactions. This investigation examines the gross morphology of Pontoniinae compound eyes and superficial optical parameters with reference to their symbiotic relationship or lifestyle category; free-living, ectosymbiont, endosymbiont (bivalves) or endosymbiont (non-bivalves). The eye morphologies of free-living and ectosymbiotic species are very similar, yet differ from both forms of endosymbiotic species. Endosymbionts have significantly smaller and simpler eyes with larger facets and bigger interommatidial angles and eye parameters for increased sensitivity levels. However bivalve endosymbionts form an intermediary group between non-bivalve endosymbionts and ectosymbionts as a result of their more active lifestyle. The accessory eye or "nebenauge", although of uncertain function, commonly occurs in free-living Pontoniinae species but rarely in endosymbionts apart from in more primitive species. The variation in morphology reflects tensions between functional requirements and ecological pressures that have strongly influenced eye design in Pontoniinae. © 2014 Dobson et al
Transfected Mosquito Vectors
A method is provided for producing an artificial infection in a Culicidae (mosquito) species. The mosquitoes include species within the subfamilies Culicinae and Anophelinae, and the species include Aedes albopictus, Aedes aegypti and Aedes polynesiensis infected with a Wolbachia infection. The infection may be a strain of Wolbachia which does not normally or naturally infect the selected mosquito species. The artificially infected Aedes mosquito can be introduced into a mosquito population to control the reproduction capability of the population by introducing an incompatible Wolbachia infection. The present method can be used as a novel means to limit mosquito-borne pathogens and thus control or prevent mosquito-borne diseases such as dengue, lymphatic filariasis, etc
ReDigi and the Resale of Digital Media: The Courts Reject a Digital First Sale Doctrine and Sustain the Imbalance Between Copyright Owners and Consumers
Part II of this comment will explain the history of the first sale doctrine, observe how Congress has modified the doctrine over time, and examine how the courts have interpreted the doctrine in light of various technological innovations. Part III will address the problems associated with digital media and examine the concerns of both copyright owners and consumers surrounding a digital first sale doctrine. Part IV will discuss the recent federal district court case, Capitol Records, LLC v. ReDigi Inc., which dealt with the issue of the first sale doctrine’s applicability to digital media, and explain why the court missed a prime opportunity to improve copyright law and ensure its compatibility with current technology. Part V offers a concise Congressional solution to expressly allow the first sale doctrine’s application to digital media, paired with some practical restrictions, to effectively balance the interests of both copyright owners and consumers. Part VI concludes that the first sale doctrine is currently broad enough to incorporate digital media in order to enhance consumer rights in the modern age. However, as the courts have declined to take up the issue, Congress can create an expressly balanced “digital first sale doctrine,” implementing subtle solutions to curtail the concerns of copyright owners
[Review of] Ronald T. Takai . Violence in The Black Imagination: Essays and Documents. Expanded Editions
Originally published in 1972 and re-issued in 1993, Violence in the Black Imagination was an early attempt to overcome the pitfalls of what some academicians have termed disjunctive scholarship. Ronald Takaki reminds us that too often fiction is analyzed narrowly as an art rather than as social documents that might be useful not only to those studying literature but also to those examining history. Reviewing three fictional works, Takaki makes a case or their use as historical sources. He asserts that “black fiction not only adds to our already limited number of ante-bellum black written documents, but also represents a particularly important genre of evidence” (12). Nineteenth century fiction, according to Takaki, lends insight into the feelings and emotions African Americans harbored towards slavery -- insight often lost in traditional historical sources
[Review of] Kenneth Robert Janken. Rayford W. Logan and the Dilemma of the African-American Intellectual
Rayford W. Logan has been little more than an obscure shadow in African-American historicity leaving, as his biographer notes, a rich intellectual legacy without, it appears, having left a visible imprint on historic events (198). Earning a Ph.D. from Harvard in 1932, Logan proceeded to become a trailblazer in the field of African-American history, seeking to use his intellect in the fight against racism
