AIM To analyse meta-analyses included in systematic reviews (SRs) published in leading orthodontic journals and the Cochrane Database of Systematic Reviews (CDSR) focusing on orthodontic literature and to assess the quality of the existing evidence. MATERIALS AND METHODS Electronic searching was undertaken to identify SRs published in five major orthodontic journals and the CDSR between January 2000 and June 2014. Quality assessment of the overall body of evidence from meta-analyses was conducted using the Grading of Recommendations Assessment, Development and Evaluation working group (GRADE) tool. RESULTS One hundred and fifty-seven SRs were identified; meta-analysis was present in 43 of these (27.4 per cent). The highest proportion of SRs that included a meta-analysis was found in Orthodontics and Craniofacial Research (6/13; 46.1 per cent), followed by the CDSR (12/33; 36.4 per cent) and the American Journal of Orthodontics and Dentofacial Orthopaedics (15/44; 34.1 per cent). Class II treatment was the most commonly addressed topic within SRs in orthodontics (n = 18/157; 11.5 per cent). The number of trials combined to produce a summary estimate was small for most meta-analyses with a median of 4 (range: 2-52). Only 21 per cent (n = 9) of included meta-analyses were considered to have a high/moderate quality of evidence according to GRADE, while the majority were of low or very low quality (n = 34; 79.0 per cent). CONCLUSIONS Overall, approximately one quarter of orthodontic SRs included quantitative synthesis, with a median of four trials per meta-analysis. The overall quality of evidence from the selected orthodontic SRs was predominantly low to very low indicating the relative lack of high quality of evidence from SRs to inform clinical practice guidelines.

The transistor was an American invention, and American firms led the world in semiconductor production and innovation for the first three decades of that industry's existence. In the 1980s, however, Japanese producers began to challenge American dominance. Shrill cries arose from the literature of public policy, warning that the American semiconductor industry would soon share the fate of the lamented American consumer electronics business. Few dissented from the implications: the only hope for salvation would be to adopt Japanese-style public policies and imitate the kinds of capabilities Japanese firms possessed. But the predicted extinction never occurred. Instead, American firms surged back during the 1990s, and it now seems the Japanese who are embattled. This striking American turnaround has gone largely unremarked upon in the public policy literature. And even scholarship in strategic management, which thrives on stories of success instead of stories of failure, has been comparatively silent. Drawing on a more thorough economic history of the worldwide semiconductor industry (Langlois and Steinmueller 1999), this essay attempts to collect some of the lessons for strategy research of the American resurgence. We argue that, although some of the American response did consist in changing or augmenting capabilities, most of the renewed American success is in fact the result not of imitating superior Japanese capabilities but rather of taking good advantage of a set of capabilities developed in the heyday of American dominance. Serendipity played at least as important a role as did strategy.

(beginning of rainbow smelt executive summary) Evidence indicates that anadromous rainbow smelt (Osmerus mordax) populations in Connecticut and elsewhere in the northeast United States have severely declined. Several sampling programs have documented declines in Connecticut’s smelt populations over the last three decades (Marcy 1976a, Marcy 1976b, Millstone Environmental Laboratory 2005). Similar declines have also been documented in the Hudson River (ASA Analysis & Communication 2005) and in Massachusetts (personal communication, Brad Chase, MA Division of Marine Fisheries 2004). Recreational and commercial fisheries in the region for this species have virtually ceased (Blake and Smith 1984). The Connecticut Fish Advisory Committee of the Endangered Species Program has recommended that rainbow smelt be listed as threatened in Connecticut, and the National Marine Fisheries Service (2004) has recently listed rainbow smelt as a Federal Species of Concern. The purpose of this project is to develop an environmental history of rainbow smelt in Connecticut and surrounding regions, and document the current status of populations in Connecticut waters. An environmental history that assesses trends in abundance, environmental threats and historical efforts to ameliorate the threats will contribute to regional efforts to conserve these fish. Comprehensive review of the regional literature and trends associated with rainbow smelt has not been undertaken since Kendall (1926). Assessment of current abundance, distribution, areas of critical habitat, and whether the species is presently reproducing in state waters is critical for clarifying conservation status, designing a monitoring program and developing a recovery or enhancement plan, if this appears to be necessary. (beginning of tomcod executive summary) Atlantic tomcod (Microgadus tomcod) are believed to have declined significantly in Connecticut and other estuaries of the Northeast and Middle Atlantic states. Several monitoring programs indicate that the species is scarce and/or declining in the region’s estuaries (Gottschall and Pacileo 2004, Molnar 2004, Millstone Environmental Laboratory 2005, ASA Analysis and Communication 2005). Once-active recreational (NMFS MRFSS 2005, http://www.st.nmfs.gov) and commercial fisheries for this species in Connecticut are now dormant. For the past 10 years, the Connecticut Fish Advisory Committee of the Endangered Species Program has recommended that studies be undertaken to quantify the status of tomcod populations and to determine if conservation actions should be initiated. The purpose of this project is to develop an environmental history of Atlantic tomcod in Connecticut and surrounding regions, and document the current status of populations in Connecticut waters. An environmental history that assesses trends in abundance, environmental threats and historical efforts to ameliorate the threats will contribute to regional efforts to conserve these fish. Assessment of current abundance, distribution, areas of critical habitat, and whether the species is presently reproducing in state waters is critical for determining conservation status, designing a monitoring program and developing a recovery or enhancement plan, if this appears to be necessary.

The late eighteenth-century author Frances Burney is best known for popularizing the “comedy of manners,” a literary style later adopted by Jane Austen. Burney’s novels, journals, and plays offer an intriguing commentary on contemporary social customs and etiquette. In particular, she voices the concerns and desires of women, leading scholars to focus on the feminist overtones of her writing. Although she carefully examined female roles in the household and family structure, Burney also provided an insider’s perspective into London high life. As an acclaimed author and member of the royal court, Burney offers a rare insight into the lives of the urban elite. For these reasons, I have chosen to examine three of her works within the context of their London setting. In Evelina, Cecilia, and The Witlings, Burney examines women’s struggle for independence against the backdrop of the city. These works offer a new interpretation of the female Bildungsroman, or coming of age story. Burney shows how London life influences her heroines’ expectations, ambitions and desires. Evelina’s coming of age centers around the quest for family and social acceptance, while the two Cecilias of Cecilia and The Witlings confront the financial pressures that accompany their inheritance. Ultimately, the three protagonists learn important lessons that are specific to city life. Although Burney concludes each story with the heroine’s marriage, her focus is not on romance, as has been suggested, but on the cultural landscape of the city. Coming of age in her stories is inextricably connected to the diverse challenges and opportunities presented to urban women.

Naltrexone, an opioid antagonist, was the second drug approved for treatment of alcohol dependence in the U.S. Its approval followed two landmark studies published in the U.S. in 1992. [1, 2] These studies showed that a combined treatment of naltrexone and behavioral therapy reduced alcohol consumption in alcoholics. Opioid antagonists decrease craving for alcohol and help to reduce drinking by blocking opioid peptide receptors in the body that are active in a dopamine chemical reward system. ^ Despite their usefulness, opioid antagonists have been underutilized. Health providers not educated in the use of opioid antagonists hold the view that opioid antagonist therapy is ineffective. However, it is apparent from the relevant literature that this therapy, when properly understood and targeted, has the potential to make a positive contribution in treating alcohol dependent patients. ^ This thesis will review the scientific literature and the present body of knowledge regarding opioid antagonists (naltrexone) and their pharmacological role in treating alcohol dependence.^

To address growing concern over the effects of fisheries non-target catch on elasmobranchs worldwide, the accurate reporting of elasmobranch catch is essential. This requires data on a combination of measures, including reported landings, retained and discarded non-target catch, and post-discard survival. Identification of the factors influencing discard vs. retention is needed to improve catch estimates and to determine wasteful fishing practices. To do this we compared retention rates of elasmobranch non-target catch in a broad subset of fisheries throughout the world by taxon, fishing country, and gear. A regression tree and random forest analysis indicated that taxon was the most important determinant of retention in this dataset, but all three factors together explained 59% of the variance. Estimates of total elasmobranch removals were calculated by dividing the FAO global elasmobranch landings by average retention rates and suggest that total elasmobranch removals may exceed FAO reported landings by as much as 400%. This analysis is the first effort to directly characterize global drivers of discards for elasmobranch non-target catch. Our results highlight the importance of accurate quantification of retention and discard rates to improve assessments of the potential impacts of fisheries on these species.

"...is a novel that combines literature and art to create a unique postmodern object. It was published just over a decade ago, and in that time numerous scholars and students have written papers and articles on it. Within these articles, the themes are usually about deconstruction, the house as a digital object, the house's lack of homeliness, or characters who claim authorial presence. Danielewski distance himself from that role. The house and its impossible labyrinth are the central feature of the book. A house should provide stability, but this house shifts its rooms and walls at random. A house should protect its occupants, but this one kills people. This house links itself into an infinite amount of information through its use of the internet as an influence and a stylistic device, but it has nothing but an absence in its very foundation, an empty labyrinth with an unseen monster."
