(Matrix Presented) Treatment of aniline with n-butyllithium and then trimethyltin chloride gave the tin amide (PhNH-SnMe3) in situ. Without isolation of the tin amide reaction with bromine and workup with aqueous fluoride ion gave p-bromoaniline in 76% yield, with no dibromoaniline or o-bromoaniline. Application of this sequence to 11 different aromatic amines gave selective bromination in 36-91% yields, without formation of dibromides. This constitutes a good general method for the regioselective bromination of aromatic amines.

We report dramatic improvement in electrical properties of 4H-SiC/SiO2 interface by depositing an ultra-thin layer of silicon nitride on 4H-SiC prior to formation of silicon oxide and annealing. AC conductance measurements reveal interface-trap density equal to or below 1 × 1012/cm2- eV at energies near the conduction band edge. XPS spectra confirm the presence of N at the interface and suggest possible bonding between N and C. © (2002) Trans Tech Publications, Switzerland.

Gastroesophageal reflux disease can usually be successfully managed with conservative medical treatment. Anti-reflux surgery is a safe alternative when treatment fails or patients desire a more definitive treatment option. Through a case study approach, this article describes the indications for surgery, the essentials of the authors’ multi-disciplinary approach to care and the components of a well-designed education plan for a patient undergoing laparoscopic Nissen fundoplication. Although most patients do well after surgery, diligent nursing care is required before and after surgery to prevent or manage complications and ensure patients have a rapid recovery and successful outcome. © 2001 Lippincott Williams & Wilkins, Inc.

Marks (2001) is critical of our study of nest-site selection in Great Horned Owls (Bubo virginianus) because we compared our data from owl nests with data from random points rather than from unused stick nests. We argue that Great Horned Owls have so many options for nesting in eastern forests that there is little constraint on nest-site selection. Therefore, their choice of nest sites is determined largely by vegetation characteristics in the surrounding landscape, and comparison of owl nests with random points is the best way to assess nest-site selection. Furthermore, we believe that use of unused nests as controls, as advocated by Marks, is biased because control nests will have many of the same characteristics as nests used by owls.

In our postmodern visual culture, the idea of spectacle conjures images of excess. In defining spectatorship, we emphasize the visual, drawing physical eyewitnesses toward the spectacular moment itself and into the reification of that moment on the film screen. However, recent Hollywood cinema has challenged the notion that all spectacle must take place within the realm of the visual, as many films strive to reach spectators aurally, via their soundtracks. In particular, popular song has been used in many commercially successful films to re-create each spectator's relationship with his or her past. Films with best-selling pop soundtracks, such as The Wedding Singer and Romy and Michelle's High School Reunion, among others, have financially exploited the spectator's attention to familiar song within comedic narratives, prompting viewers to purchase collections of songs they may already own, motivated by nostalgia and pleasant rearrangements of these songs within light, entertaining narratives. In other cases, “retro” films such as 54 and The Last Days of Disco have attempted to capitalize on the popularity of musical trends, such as disco, to revisit what the “scene” meant to its patrons, as well as what disco might mean commercially to new generations. But rarely do the songs in this type of film serve as anything but collective backdrop or the means by which a filmmaker might establish setting, particularly in terms of a decade. They merely reconfigure radio programming, reorder Top 40 hits for a theatrical space. © 2001 Taylor & Francis Group, LLC.

The current paper describes the process and results of an effort to find a way to effectively manage and diffuse prevention knowledge. This study shows the role that today's communication technologies can play in ensuring collaboration and participation in both the design and use of a knowledge management system (KMS) for prevention research, practice and policy. In the context of this study, 'prevention research' includes primary through tertiary prevention efforts consistent with general applied public health research in the US. An online Delphi study was used to engage a set of prevention research constituencies in the design of a mechanism to enhance the potential for effective technology transfer. A three-round Delphi was conducted with 58 stakeholders and key informants involved in prevention: government-level policy makers, researchers and front-line practitioners. The study resulted in consensus on 34 functions and 32 output/content elements of a proposed web-based KMS called Prevention-Effects.net. The paper also describes the implications of both the processes of development and the benefits of the proposed system for those interested in prevention.

Pain is a prevailing clinical problem among older adults resulting in systemic agitation and altered quality of life. Although the possibility remains that older adults experience and report less pain, the need exists to objectively evaluate pain in order to provide the most effective pain management. Several standardized tools are available to assess pain in older adults at baseline and at subsequent, frequent intervals. Following an objective assessment, pain may be managed with pharmacologic and nonpharmacologic methods.

Objective: To compare the effects of low doses of creatine and creatine loading on strength, urinary creatinine concentration, and percentage of body fat. Design and Setting: Division IA collegiate football players took creatine monohydrate for 10 weeks during a sport-specific, periodized, off-season strength and conditioning program. One-repetition maximum (1-RM) squat, urinary creatinine concentrations, and percentage of body fat were analyzed. Subjects: Twenty-five highly trained, Division IA collegiate football players with at least 1 year of college playing experience. Measurements: We tested strength with a 1-RM squat exercise before, during, and after creatine supplementation. Percentage of body fat was measured by hydrostatic weighing before and after supplementation. Urinary creatinine concentration was measured via light spectrophotometer at 0, 1, 3, 7, 14, 21, 28, 35, 42, 48, 56, and 63 days. An analysis of variance with repeated measures was computed to compare means for all variables. Results: Creatine supplementation had no significant group, time, or interaction effects on strength, urinary creatinine concentration, or percentage of body fat. However, significant time effects were found for 1-RM squat and fat-free mass in all groups. Conclusions: Our data suggest that creatine monohydrate in any amount does not have any beneficial ergogenic effects in highly trained collegiate football players. However, a proper resistance training stimulus for 10 weeks can increase strength and fat-free mass in highly trained athletes.

This article, extracted from a larger study, is attentive to the national folk culture of African-American communities - especially rumor and legend - in a number of city centers. The study begins with Washington, D.C., as a representative model to examine the role of complexion-related lore in black neighborhoods, organizations, and institutions, and then extends outward to other urban areas. Complexion lore, the article argues, functioned as a sophisticated negotiation of racism, wherein black residents complicated American urban principles of inclusion and exclusion by integrating color notions into institutional oral history.

Societal drivers, as well as trends in education and health care, are advancing the practice doctorate in nursing. For nurse practitioner preparation, the current resurgence of interest in the practice doctorate could precipitate change that mimics the evolution from post-basic certificate to Master's level education. The National Organization of Nurse Practitioner Faculties (NONPF) is a resource for the study of the practice doctorate relative to quality nurse practitioner education. This article will offer some insights into the movement toward the practice doctorate by describing, from the NP perspective, the societal impetus for change, the historical perspective of NP and doctoral education, the 4 Ws (why, what, where, and when) of the movement, and some of the myths and realities about the practice doctorate. © 2005 Online Journal of Issues in Nursing.

Using the printed works of two French cartographers, Alexis-Hubert Jaillot and Guillaume Delisle, I investigate how the changing interests of the government directed not only the process of map-making but the rhetoric evident in printed maps and atlases. Jaillot, a commercial map publisher flourishing during the second half of the seventeenth century, produced maps that participated in the fabrication of the image of Louis XIV. Maps served this "cult of image" and contributed to a multimedia show to glorify the reign of the Sun King and to support his personal state - l'état, c'est moi. In the eighteenth century, while a rhetoric of image was still present on printed maps, the "cult of image" was dead and mapping appealed to the rise of the impersonal or bureaucratized state - l'état, c'est l'état. Delisle produced maps as instruments of statecraft that aided the state in furthering its domestic and international interests. In particular, printed maps of the Americas served the government's need to acquire greater territorial control. While images were still powerful on New World maps, the French boundary claims, egregious to some, if uncontested could be produced time and again as a true representation and legitimization of territorial control.
