This white paper discusses the evolution of the satellite radio industry during its first decade. Since their inception, both Sirius & XM have gone through major developments as well as changes include the acquisition of Sirius by XM in March 2008. This paper is an important to the current literature in this field as it preserves the history of the origins and development of the satellite radio industry during its first and most important decade.

Purpose: Silicone oil (SO) is often used as an intraocular tamponade in repairs of retinal detachments. It may be associated with complications such as cataract, glaucoma, keratopathy, subretinal migration of oil, fibrous epiretinal and sub retinal proliferations, and oil emulsification. The purpose of this report is to describe a rare phenomenon of intraocular silicone oil migration into the cerebral ventricles, which may later be mistaken for intraventricular hemorrhages on neuroimaging. Methods: Case report with literature review. Results: A patient with a history of retinal detachment repair with intraocular SO presented with headaches. Neuroimaging revealed SO migration to the cerebral ventricles. The patient was treated conservatively with symptom management and headaches resolved. Conclusions: We present a case of intraocular SO migration to the cerebral ventricles and review the current literature. We also propose two mechanisms for this phenomenon.

Triamcinolone acetonide is a synthetic glucocorticoid used to treat numerous acute and chronic inflammatory conditions. The various side effects of this drug from parenteral administration are well documented in the literature. In this study, three patients present with a rare side effect of violaceous dermal pigmentation. To the best of the authors' knowledge, this finding is rarely presented in the current literature. The purpose of this study is to provide awareness of a less-documented, delayed side effect from triamcinolone acetonide administration. Although all patients presenting in this study had a known history of autoimmune disease (eg, lupus, psoriatic arthritis) further research is needed to suggest a possible association between dermal violaceous change and the use of triamcinolone.

Post-Wisconsinian uplift of West, North and East Greenland has been estimated on the basis of information in current literature and compared to the data collected by the author in central West Greenland. For West and North Greenland the dated uplift allows an estimate to be made of the age of former shore-lines, which in turn have been used to date the stages of the extent of the Inland lce. The results have been compared with published information on the age of glacial stages in East Greenland. The estimated ages of the ice margin stages imply a history of deglaciation in West (and North?) Greenland comparable to that of North America. In both areas the major deglaciation took place after the Younger Dryas and a marked halt took place in Boreal times. It is possibie that the history of East Greenland is more closely related to that of Scandinavia where a widespread deglaciation took place prior to the Younger Dryas. The deglaciation of North Greenland was interrupted by a marked readvance or readvances during the climatic optimum. It is possible that the northward shift of the low pressure centres during this period led to an increased accumulation on the northern part of the Inland lce.

Most of the current literature in the field of gyroscopic theory and in the use of gyroscopic instruments for the determination of azimuth begins the historical account of the subject with the work of Leon Foucault during the period 1850-1852. But little is known of the work in this field by others during the preceding half century. In this paper, the development of the gyroscope and gyro compass is traced back to a date earlier than 1813.

Developments in contemporary Latina/os media are the result not only of an exponentially growing Latina/o population in the United States but also of the synergy between transformations in the global political economy and the emergence of new media platforms for production, distribution, and consumption. To reflect upon the emergence of the industry is to consider the politics of the labeling of the Latina/o community and the eventual configuration of a market audience. It also requires a confrontation with the cultural history of representations and stereotypes of Latina/os, particularly in radio, TV, film, and the internet, and the transnational aesthetics and dynamics of media produced by and/or for Latina/os in the United States. If the notion of media revolves around a technological means of communication, it also encompasses the practices and institutions from within which the Latina/o communities are imagined, produced, and consumed. At the start of the 21st century, the idea of Latina/os in media revolved around a handful of Latina/o stars in Hollywood who often performed stereotypical representations, a racialized and marginal Spanish-language radio industry, and two Spanish television networks, Univision and Telemundo. A more complex constellation of representations has evolved in both mainstream and Spanish-language media, among them new platforms for production and resistance, including social media (e.g., Facebook, Instagram, Snapchat), radio podcasts and streaming services (e.g., Hulu and Netflix), and a more active and engaged audience that consumes media in Spanish, English, and even Spanglish.

AbstractMini-sabbaticals are formal short-term training and educational experiences away from an investigator’s home research unit. These may include rotations with other research units and externships at government research or regulatory agencies, industry and non-profit programs, and training and/or intensive educational programs. The National Institutes of Health have been encouraging training institutions to consider offering mini-sabbaticals, but given the newness of the concept, limited data are available to guide the implementation of mini-sabbatical programs. In this paper, we review the history of sabbaticals and mini-sabbaticals, report the results of surveys we performed to ascertain the use of mini-sabbaticals at Clinical and Translational Science Award hubs, and consider best practice recommendations for institutions seeking to establish formal mini-sabbatical programs.

Malaysia and Indonesia account for 90 percent of global exports of palm oil, forming one of the largest agricultural clusters in the world. This article uses archival sources to trace how this cluster emerged from the rubber business in the era of British and Dutch colonialism. Specifically, the rise of palm oil in this region was due to three interrelated factors: (1) the institutional environment of the existing rubber cluster; (2) an established community of foreign traders; and (3) a trading hub in Singapore that offered a multitude of advanced services. This analysis stresses the historical dimension of clusters, which has been neglected in the previous management and strategy works, by connecting cluster emergence to the business history of trading firms. The article also extends the current literature on cluster emergence by showing that the rise of this cluster occurred parallel, and intimately related, to the product specialization within international trading houses.


Significance Ahead of the rollout of the Liberal government’s new defence white paper, Minister of Foreign Affairs Chrystia Freeland delivered a speech in the House of Commons arguing that Canada’s membership of NATO and history of peacekeeping are core elements of its internationalist foreign policy. The government of Prime Minister Justin Trudeau wishes to finance greater Canadian involvement in multilateral security missions and institutions of liberal global governance. Impacts Defence issues are not politically salient to Canadian voters, but government backtracking on policy is. High polling support for peacekeeping would probably evaporate in the event of Canadian losses abroad. Operational setbacks could see Trudeau’s Liberals bleed support to their New Democratic and Conservative rivals.

Anesthesiologists and sedationists often use propofol as the main anesthetic agent for brief procedures, such as esophagogastroduodenoscopy with biopsy for eosinophilic esophagitis (EoE). Pediatric patients presenting for endoscopy often have a history of reflux as well as drug and food allergies. Specifically, patients with EoE often have sensitivity to egg and soy, as well as milk and dairy products, tree nuts/peanuts, and seafood (fish/shellfish). Propofol use is often cited as a contraindication in patients with hypersensitivity to egg and soy. Current literature does not support avoiding propofol in egg- and soy-allergic patients. Most practitioners, however, continue to avoid propofol in patients with a history of egg anaphylaxis due to lack of evidence supporting its safe use in this population.
