Seismic Design for Buildings

This updated manual with revised seismic design provisions governs the design and construction of Army, Navy, and Air Force facilities and supersedes the April 1973 issue. Basic criteria are stated herein with augmentations and clarifications of the criteria. Also, commentary and design examples are included to provide comprehensive applications and guidelines for the seismic-resistant design of facilities. The organization of the manual has been revised to present the topics in a more orderly manner. The dynamic analysis approach for seismic design is not covered but its use is not precluded in this manual. The basic criteria cited are the Recommended Lateral Force Requirements and Commentary as published by the Structural Engineers Association of California (SEAOC). The design concepts and applications for the design of: (1) supports for electrical, mechanical end architectural elements and (2) structures other than buildings, have been revised. The applications of essential, high risk and other occupancy type structures are included with the use of the importance factors vice high-loss potential and low-loss potential facilities in the 1973 issue. The general direction for the revision of the manual was by a Department of Defense Tri-Services Seismic Design Committee, i.e., representatives of the Office of the Chief of Engineers, Headquarters, US Army; Naval Facilities Engineering Command, Headquarters, US Navy; and Directorate of Engineering and Services, Headquarters, US Air Force. Detailed development of the manual was under the direction of the Office of the Chief of Engineers, Washington, DC and the US Army Division Engineer, South Pacific, San Francisco, California. Coordination was maintained with the Naval Facilities Engineering Command at Headquarters, Washington, DC, and Western Division, San Bruno, California; and US Air Force Civil Engineering Offices at Headquarters, Washington, DC, and Western Regional Office, San Francisco, California

A Review of Risk Matrices Used in Acute Hospitals in England.

In healthcare, patient safety has received substantial attention and, in turn, a number of approaches to managing safety have been adopted from other high-risk industries. One of these has been risk assessment, predominantly through the use of risk matrices. However, while other industries have criticized the design and use of these risk matrices, the applicability of such criticism has not been investigated formally in healthcare. This study examines risk matrices as used in acute hospitals in England and the guidance provided for their use. It investigates the applicability of criticisms of risk matrices from outside healthcare through a document analysis of the risk assessment policies, procedures, and strategies used in English hospitals. The findings reveal that there is a large variety of risk matrices used, where the design of some might increase the chance of risk misprioritization. Additionally, findings show that hospitals may provide insufficient guidance on how to use risk matrices as well as what to do in response to the existing criticisms of risk matrices. Consequently, this is likely to lead to variation in the quality of risk assessment and in the subsequent deployment of resources to manage the assessed risk. Finally, the article outlines ways in which hospitals could use risk matrices more effectively

A Comparative Analysis of Competency Frameworks for Youth Workers in the Out-of-School Time Field

Research suggests that the quality of out-of-school time (OST) programs is related to positive youth outcomes and skilled staff are a critical component of high quality programming. This descriptive case study of competency frameworks for youth workers in the OST field demonstrates how experts and practitioners characterize a skilled youth worker. A comparative analysis of 11 competency frameworks is conducted to identify a set of common core competencies. A set of 12 competency areas that are shared by existing frameworks used in the OST field are identified. The age of youth being served, descriptions of mastery for each competency area, an emphasis on developing mid-level managers, and incorporating research emerge as factors that should be addressed in future competency frameworks

Dietary intake and stress fractures among elite male combat recruits

<p>Abstract</p> <p>Background</p> <p>Appropriate and sufficient dietary intake is one of the main requirements for maintaining fitness and health. Inadequate energy intake may have a negative impact on physical performance which may result in injuries among physically active populations. The purpose of this research was to evaluate a possible relationship between dietary intake and stress fracture occurrence among combat recruits during basic training (BT).</p> <p>Methods</p> <p>Data was collected from 74 combat recruits (18.2 ± 0.6 yrs) in the Israeli Defense Forces. Data analyses included changes in anthropometric measures, dietary intake, blood iron and calcium levels. Measurements were taken on entry to 4-month BT and at the end of BT. The occurrence of stress reaction injury was followed prospectively during the entire 6-month training period.</p> <p>Results</p> <p>Twelve recruits were diagnosed with stress fracture in the tibia or femur (SF group). Sixty two recruits completed BT without stress fractures (NSF). Calcium and vitamin D intakes reported on induction day were lower in the SF group compared to the NSF group-38.9% for calcium (589 ± 92 and 964 ± 373 mg·d^-1, respectively, <it>p </it>< 0.001), and-25.1% for vitamin D (117.9 ± 34.3 and 157.4 ± 93.3 IU·d^-1, respectively, <it>p </it>< 0.001). During BT calcium and vitamin D intake continued to be at the same low values for the SF group but decreased for the NSF group and no significant differences were found between these two groups.</p> <p>Conclusions</p> <p>The development of stress fractures in young recruits during combat BT was associated with dietary deficiency before induction and during BT of mainly vitamin D and calcium. For the purpose of intervention, the fact that the main deficiency is before induction will need special consideration.</p
