Nutritional culturomics and big data: Macroscopic patterns of change in food, nutrition and diet choices.
Nutritional culturomics and big data: Macroscopic patterns of change in food, nutrition and diet choices. Curr Pharm Biotechnol. 2019 Feb 11;: Authors: Troumbis AY, Hatziantoniou M, Vasios GK Abstract Nutritional culturomics (NCs) is a specific focus area of culturomics epistemology developing digital humanities and computational linguistics approaches to search for macro-patterns of public interest in food, nutrition and diet choice as a major component of cultural evolution. Cultural evolution is considered as driver at the interface of environmental and food science, economy and policy. The paper presents an epistemic programme that builds on the use of big data from web-based services such as Google Trends, Google Adwords or Google Ngram Viewer. A comparison of clearly defined NCs in terms of geography, culture, linguistics, literacy, technological setups or time period might be used to reveal variations and singularities in public's behavior in terms of adaptation and mitigation policies in the agri-food and public health sectors. The proposed NC programme is developed along major axes: (1) the definition of a NC; (2) the reconstruction of food and diet histories; (3) the nutrition related epidemiology; (4) the understanding of variability of NCs; (5) the methodological diversification of NCs; (6) the quantifiable limitations and flaws of NCs. A series of indicative examples are presented regarding these NC epistemology components. PMID: 307470...

Diplomates of the American Board of Thoracic Surgery (ABTS) who plan to participate in the 10-Year Milestone for the Maintenance of Certification (MOC) process as Certified-Active must hold a currently valid, full, and unrestricted license to practice medicine. Diplomates must have privileges at a hospital(s) accredited by the JCAHO or other institutions judged acceptable by the Board. Diplomates must also submit letter(s) of reference documenting their level of clinical activity and stature within the surgical community from the VP of Medical Affairs and one other re sponsible member on staff at their principal hospital.
The American Board of Thoracic Surgery's Maintenance of Certification program was adopted 9 years ago. Since that time, there has been a continuous evaluation in the Board's thinking about the overall process, based upon internal discussions and input from our Diplomates.

BoucherieAbstractEarly or tardy surgeries are frustrating for both patients and personnel, and cause inefficient use of resources at the operating rooms. The stochastic Earliness/Tardiness (E/T) scheduling problem addresses this by minimizing the total expected deviation of the surgery completion times from the planned completion times. We introduce the concept of E/T-concavity as a property of a probability distribution if the E/T costs are concave as a function of the standard de...
