Robert B. Dorman, Christopher J. Miller, Daniel B. Leslie, Federico J. Serrot, Bridget Slusarek, Henry Buchwald, John E. Connett, Sayeed Ikramuddin
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0032506
Abstract: Background and Objectives Complications resulting in hospital readmission are important concerns for those considering bariatric surgery, yet present understanding of the risk for these events is limited to a small number of patient factors. We sought to identify demographic characteristics, concomitant morbidities, and perioperative factors associated with hospital readmission following bariatric surgery. Methods We report on a prospective observational study of 24,662 patients undergoing primary RYGB and 26,002 patients undergoing primary AGB at 249 and 317 Bariatric Surgery Centers of Excellence (BSCOE), respectively, in the United States from January 2007 to August 2009. Data were collected using standardized assessments of demographic factors and comorbidities, as well as longitudinal records of hospital readmissions, complications, and mortality. Results The readmission rate was 5.8% for RYGB and 1.2% for AGB patients 30 days after discharge. The greatest predictors for readmission following RYGB were prolonged length of stay (adjusted odds ratio [OR], 2.3; 95% confidence interval [CI], 2.0–2.7), open surgery (OR, 1.8; CI, 1.4–2.2), and pseudotumor cerebri (OR, 1.6; CI, 1.1–2.4). Prolonged length of stay (OR, 2.3; CI, 1.6–3.3), history of deep venous thrombosis or pulmonary embolism (OR, 2.1; CI, 1.3–3.3), asthma (OR, 1.5; CI, 1.1–2.1), and obstructive sleep apnea (OR, 1.5; CI, 1.1–1.9) were associated with the greatest increases in readmission risk for AGB. The 30-day mortality rate was 0.14% for RYGB and 0.02% for AGB. Conclusion Readmission rates are low and mortality is very rare following bariatric surgery, but risk for both is significantly higher after RYGB. Predictors of readmission were disparate for the two procedures. Results do not support excluding patients with certain comorbidities since any reductions in overall readmission rates would be very small on the absolute risk scale. Future research should evaluate the efficacy of post-surgical managed care plans for patients at higher risk for readmission and adverse events.
Adsorptive Removal of Ni(II) from Water Using Alginate-Fixed Water Hyacinth: Effect of Organic Substances  [PDF]
Courtie Mahamadi, Bridget Madocha
American Journal of Analytical Chemistry (AJAC) , 2013, DOI: 10.4236/ajac.2013.48047
Abstract:

The potential of water hyacinthEichhornia crassipes biomass immobilized in calcium alginate for the adsorption of Ni(II) from water was studied using the Langmuir and Freundlich adsorption models. The equilibrium adsorption data were obtained at different initial Ni(II) concentrations = 0.05-2 mg/L, temperature = 30℃ ± 0.2℃, agitation rate = 150 rpm, equilibration time = 3 hr, biosorbent dose =4 g/L, and pH range = 4-7.4. Langmuir isotherms gave monolayer sorption capacities (qm) of 26.5, 44.3 and 53.0 mg/g for the removal of Ni(II) in the presence of methanol, without added organic substance, and in the presence of acetonitrile, respectively. These findings were also confirmed by the trend in the Freundlich isotherm parameter (1/n < 1). Interpretation of the sorption data in terms of the separation factor, SF, suggested that the removal of Ni(II) from water mainly occurred through a chemisorption mechanism. Desorption experiments to recover Ni(II) from the adsorbent showed that highest amounts of the metal could be removed from the adsorbent when previously adsorbed in the presence of 1-(2-Thiazolylazo)-2-naphtol (TAN) (>90%). The results from these studies indicated that E. crassipes fixed on calcium alginate beads is a viable metal enrichment media that can be used freely immersed in solution to achieve very high adsorption capacities and possible preconcentration of Ni(II) in aquatic environments.

Developing a Communications Plan for Library Screencasts
Bridget Schumacher,Bridget Schumacher
Journal of Library Innovation , 2012,
Abstract: Encouraged to explore and implement technology, many librarians create screencasts to supplement library instruction. Without a structured creation process, a number of communications issues can result, including: duplication of topics; absence of library branding; and lack of centralized availability to all screencasts. To create a more cohesive online presence, establishing a communications plan is recommended. This article is an account of the University Libraries within the State University of New York at Buffalo’s early experiences with screencasting, assessment of screencasting services, and the consequent development of a coherent communications plan and best practices document regarding video and screencast production.
Characteristics of Power Loss in SMC a Key for Desining the Best Values of Technological Parameters

Physics , 2013,
Abstract: Optimization of power loss in soft magnetic components basis on the choice of the best technological parameters values. Therefore, the power losses have been measured in Somaloy 500 samples for a wide range of frequency and magnetic induction. These samples have been prepared under a wide range of the hardening temperatures and pressures. The power loss characteristics have been derived by assuming that investigated samples obeyed the scaling law. Agreement obtained between experimental data and the scaling theory has confirmed this assumption. Moreover, the experimental data of the given sample have been collapsed to a single curve which represented measurements for all values of frequency an magnetic induction pick. Therefore, the scaling transforms the losses characteristics from the two dimensional surfaces to the one dimensional curves. The samples were produced according two methods: for different pressures with constant temperature and at different temperatures with constant pressure. In both cases the power losses decrease with increasing pressure and with increasing temperature. These trends in decreasing losses stopped for certain critical values of pressure and temperature, respectively. Above these values the power losses increase suddenly. Therefore, the mentioned above the critical pressure and the critical temperature are sought after solutions for optimal values. In order to reduce the parameters values set the limit curve in the pressure-temperature plane has been derive. This curve constitutes a separation curve between the parameters values corresponding to high and low losses.
Encouraging Critical Thinking in Online Threaded Discussions
Bridget Arend
Journal of Educators Online , 2009,
Abstract: Critical thinking is a highly desirable goal of online higher education courses. This article presents qualitative data from a mixed-method study that explores how asynchronous discussions within online courses influence critical thinking among students. In this study, online discussions were related to higher levels of critical thinking, but qualitative data indicate that the way discussions are used and facilitated is vital for encouraging critical thinking. Online discussions typically have the purpose of creating a space and time for informal, open-ended thinking to occur. Critical thinking appears to be best encouraged among students when a more consistent emphasis is placed on the discussions, and when instructor facilitation is less frequent but more purposeful.
The sacral stamp of Greek: Periphrastic constructions in New Testament translations of Latin, Gothic, and Old Church Slavonic
Bridget Drinka
Oslo Studies in Language , 2011,
Abstract: Among the sociolinguistc forces at work in the languages of the world, religious affiliation and the accompanying reverence for the symbols of that affiliation must rank among the most powerful. Religious texts serve as repositories of cultural tradition and become, for their followers, reliquaries of the very word of God. Besides the conservatizing, archaizing pressures which often grow up within a religious tradition, these texts also act as conduits for cultural and linguistic innovation as they spread, through transmission and translation, to surrounding populations. The New Testament (NT) represents just such a cultural conduit, providing not only a blueprint for Christian social behavior but also a pattern for Christian linguistic expression, providing a new lexicon, a special syntax, a style of its own, simple and spare. It was this style, these lexical and syntactic patterns, which came to be imbued with social value to connote membership in the Christian community, and which came to be imitated, sometimes subtly, sometimes blatantly, by translators of the New Testament.

América Latina Hoy , 2011,
Abstract: When the earthquake of 7.0 on the Richter scale struck Haiti on January 12, 2010, the forcibly displaced on and off the island were the object of emergency planning, but so too were the host populations in Haiti and the neighbouring Dominican Republic. This article seeks to examine the emergency response to the earthquake and ongoing challenges through the lens of critical mobilities, with special reference to forced migration island-wide. Who (men, women, boys and girls) is able to move, how, where, for how long and through which networks? What is the legal framework, if any, governing these movements? Who wants visibility and who prefers to move without drawing the attention of the Dominican authorities, in the context, for example, of ambiguous migration policies in the Dominican Republic towards impoverished Haitian immigrants? Cuando el terremoto de 7,0 en la escala Richter sacudió Haití el 12 de enero de 2010, los desplazados forzados tanto dentro como fuera de la isla fueron objeto de planes de emergencia, así como las poblaciones anfitrionas en Haití y República Dominicana. Este artículo se propone analizar la respuesta a la emergencia y los desafíos persistentes desde el prisma de movilidades críticas, con énfasis en la migración forzada a escala insular. Quiénes (hombres, mujeres, ni os, ni as) pueden moverse, cómo, hacia dónde, por cuánto tiempo y a través de qué tipo de redes? Cuál es el marco legal, si es que lo hay, que regula estos movimientos? Quiénes quieren visibilizarse y quiénes prefieren moverse sin llamar la atención de las autoridades dominicanas, en el contexto, por ejemplo, de las políticas migratorias ambiguas hacia los inmigrantes haitianos pobres?

Designing software to maximize learning
Bridget Somekh
Research in Learning Technology , 1996, DOI: 10.3402/rlt.v4i3.9974
Abstract: I take it as axiomatic that those involved in developing educational software intend that it should maximize learning. The evaluation of educational software, therefore, needs to focus mainly on this central issue. There are still, however, two ways in which 'maximization' can be measured: either in terms of the increase in the amount of learning, or in terms of the increase in the quality of learning. In either case, an important contributory factor in the evaluation of educational software is the amount of take-up in terms of purchase and use. The crude indicator of BSH (number of Bums on Seats for number of Hours) is of some value, because if software is not used it cannot have any impact at all on learning. But it is an indicator which should only be used with caution because badly designed software used frequently presumably does less to maximize learning than well designed software used infrequently. I am concerned here with the design of software which maximizes the quality of learning. I will also deal briefly with the issue of sensitivity to the context of use, but the wider problem of the take-up and use of software, although important and interesting, is beyond the scope of this paper. The paper is based on a review of key texts in the literature on learning, including some which relate directly to software development. I hope it will make some contribution to both the design and the evaluation of educational software.
