Social networks applied to training

In this article, we address the importance and relevance that social networks exhibit in their use as an educational resource.  This relevance relies in the possibility of implementing new learning resources or increasing the level of the participant's connectivity, as well as developing learning communities.  Also, the risk entailed from their use is discussed, especially for the students that have a low technological education or those having excessive confidence on the media.  It is important to highlight that the educational use of social networks is not a simple extension or translation of the student's habitual, recreational use, but that it implies an important change in the roles given to teachers as well as learners; from accommodative learning environments that only encourage memorization to other environments that demand an active, reflective, collaborative and proactive attitude, that require the development/acquisition of technological as well as social abilities, aptitudes and values.  It is also important to highlight that a correct implementation and adequate use will not only foment formal learning, but also informal and non-formal learning.

James Anderson's Political Economy--His Influence on Smith and Malthus

James Anderson's powerful critique of Adam Smith's position on the corn export bounty was published in 1777. It focuse d on Smith's proposition that the bounty could not lead to increased corn production because it could not increase corn's real price. Smit h's response to the critique is traced in later editions of Wealth of Nations. While Anderson's critique of Smith influenced Thomas Malthu s's writings from 1803 onwards, his theory of differential rent did n ot influence Malthus at this stage. An examination of the evolution o f Malthus's ideas on rent between 1803 and 1815, however, indicates t hat Malthus knew and used Anderson's work on rent.

Cigarette Smoking Increases Risk of Barrett’s Esophagus:An Analysis of the Barrett’s and Esophageal Adenocarcinoma Consortium

Background & Aims: Cigarette smoking has been implicated in the etiology of esophageal adenocarcinoma, but it is not clear if smoking is a risk factor for Barrett's esophagus. We investigated whether tobacco smoking and other factors increase risk for Barrett's esophagus.

Methods: We analyzed data from 5 case-control studies included in the international Barrett's and Esophageal Adenocarcinoma Consortium. We compared data from subjects with Barrett's esophagus (n = 1059) with those from subjects with gastroesophageal reflux disease (gastroesophageal reflux disease controls, n = 1332), and population-based controls (n = 1143), using multivariable logistic regression models to test associations with cigarette smoking. We also tested whether cigarette smoking has synergistic effects with other exposures, which might further increase risk for Barrett's esophagus.

Results: Subjects with Barrett's esophagus were significantly more likely to have ever smoked cigarettes than the population-based controls (odds ratio [OR] = 1.67; 95% confidence interval [CI]: 1.042.67) or gastroesophageal reflux disease controls (OR = 1.61; 95% CI: 1.331.96). Increasing pack-years of smoking increased the risk for Barrett's esophagus. There was evidence of a synergy between ever-smoking and heartburn or regurgitation; the attributable proportion of disease among individuals who ever smoked and had heartburn or regurgitation was estimated to be 0.39 (95% CI: 0.250.52).

Conclusions: Cigarette smoking is a risk factor for Barrett's esophagus. The association was strengthened with increased exposure to smoking until ~20 pack-years, when it began to plateau. Smoking has synergistic effects with heartburn or regurgitation, indicating that there are various pathways by which tobacco smoking might contribute to development of Barrett's esophagus.

Summary of the Snowmastodon Project Special Volume: A high-elevation, multi-proxy biotic and environmental record of MIS 6-4 from the Ziegler Reservoir fossil site, Snowmass Village, Colorado, USA

In North America, terrestrial records of biodiversity and climate change that span Marine Oxygen Isotope Stage (MIS) 5 are rare. Where found, they provide insight into how the coupling of the ocean-atmosphere system is manifested in biotic and environmental records and how the biosphere responds to climate change. In 2010-2011, construction at Ziegler Reservoir near Snowmass Village, Colorado (USA) revealed a nearly continuous, lacustrine/wetland sedimentary sequence that preserved evidence of past plant communities between similar to 140 and 55 lea, including all of MIS 5. At an elevation of 2705 m, the Ziegler Reservoir fossil site also contained thousands of well-preserved bones of late Pleistocene megafauna, including mastodons, mammoths, ground sloths, horses, camels, deer, bison, black bear, coyotes, and bighorn sheep. In addition, the site contained more than 26,000 bones from at least 30 species of small animals including salamanders, otters, muskrats, minks, rabbits, beavers, frogs, lizards, snakes, fish, and birds. The combination of macro- and micro-vertebrates, invertebrates, terrestrial and aquatic plant macrofossils, a detailed pollen record, and a robust, directly dated stratigraphic framework shows that high-elevation ecosystems in the Rocky Mountains of Colorado are climatically sensitive and varied dramatically throughout MIS 5 

Service Provision for Children and Young People with Acquired Brain Injury; Practice Recommendations: – International Paediatric Brain Injury Society (IPBIS).

Background: Providing appropriate rehabilitation services for Acquired Brain Injury (ABI) in childhood presents a number of challenges for caregivers, health and education professionals and the young person as they develop.
Primary Objective: To record the challenges and possible creative solutions generated by an international group of professionals to address the needs of children with ABI.
Review of Information: Recommendations were generated from children’s special interest group meetings of the International Brain Injury Association (Turin Italy, 2001, Stockholm Sweden, 2003, Melbourne Australia, 2005, Lisbon Portugal, 2008) and through meetings of the International Paediatric Brain Injury Society (IPBIS), formed in 2009. Delegates participating in the workshops were representative of nations from around the world and included The Netherlands, New Zealand, Australia, UK, Finland, Germany, South Africa, USA, Canada, Sweden, Brazil and Italy.
Outcomes: The information presented is based on a retrospective review of those meetings and the summaries of the topics considered.
