...evaluating the consequences of each choice. Tradeoffs If you got this far without a solution, it’s probably because your decision is really tricky. It also means that it has conflicting objectives — and that you’ll need to consider some hard tradeoffs between them. Week 3 Data Quality Issues When transferring data from one program to another (ie from Excel to Access), you need to consider the following: * Uniformity (data has transferred in the same manner for all records in a file). * Version (ensure format of original data and variables has not changed when data was transformed). * Completeness check (all records are transferred in the file). * Conformity check (does data look right?). * Spot check (trace some records back to their source file eg. 10 random records to see they have transferred correctly). Cleaning Data One of first and most important steps in data analysis is to verify that your data values are correct, or conform to a set of rules. * For example a variable called Gender would be expected to have only 2 values (M or F). * You need to consider the variables and their values firstly to see they are appropriate for the data they contain. * MS Access and SAS have a number of ways you can use to check for...

Because chronic pain is a major indication for medical cannabis, laws that establish access to medical cannabis may change overdose mortality related to opioid analgesics in states that have enacted them. OBJECTIVE—To determine the association between the presence of state medical cannabis laws and opioid analgesic overdose mortality. DESIGN, SETTING, AND PARTICIPANTS—A time-series analysis was conducted of medical cannabis laws and state-level death certificate data in the United States from 1999 to 2010; all 50 states...

...that acts to the event within a specified time period. A real time system depicts those systems which have to perform certain calculation within specific time period, delayed results may be considered wrong. In 2001, Shaw explained that real time systems have a very limited time constraints which are defined by the systems requirements, which reflects the aspects of outer world. Real time systems are now become important part of this modern age, safety and privacy issues and performance of such systems have also been raised .In 2000 Halang and Druzovec explained that performance in real time system depends on higher bandwidth, faster response and faster computation power. A real time systems state is dependent on a function of physical time eg; a chemical reaction continues to change its state from one state to another even after the supervising computer system is stopped. This real time system can easily be decomposed into a set of subsystems i.e. human operator, controlled object, real time computer system. A real time system must react to the stimuli with the help of the controlled object within specific time period. Typical examples of real time systems include multimedia applications, command control systems, air traffic control systems, space systems, embedded automotive electronics etc. Real time systems are classified into two categories:- * Factors outside the computer system * Factors inside the computer system Characteristics of Real time systems:- Real time...

...RESEAR CH AR TICLE Psychosocial Distress and Alcohol Use as Factors in Adolescent Sexual Behavior Among Sub-Saharan African Adolescents RANDY M. PAGE, PhDa COUGAR P. HALL, PhDb ABSTRACT BACKGROUND: This study examines the relationship between sexual behavior, alcohol use, and indicators of psychosocial distress (mental health) of adolescents in 6 sub-Saharan African countries using the Global School-based Student Health Survey (GSHS). METHODS: The sample consisted of 22,949 adolescents from Botswana, Kenya, Namibia, Uganda, Zambia, and Zimbabwe who participated in 2003 or 2004 GSHS surveys. Statistical analysis was conducted to determine whether sexual behaviors increased with levels of psychosocial distress and alcohol use. RESULTS: Sexual behaviors (having sex or having sex with 2 or more people) were associated with both psychosocial distress and alcohol use. Odds ratios showed that both boys and girls reporting psychosocial distress and alcohol use were at higher risk for having sex. Results also indicated that the likelihood of sexual behaviors increased when there was an increase in the number of psychosocial indicators and frequency of alcohol consumption. CONCLUSION: The results of this study are consistent with those conducted in the United States suggesting that sexual behavior, psychosocial distress, and substance use are interconnected. These findings highlight the need for school health education and health services in sub-Saharan Africa...

...Systematic Review and Meta-Analysis Name Affiliation Date ABSTRACT Objectives: Enlargement of the tracheoesophageal puncture (TEP) is a challenging complication after laryngectomy with TEP. We sought to estimate the rate of enlarged puncture, associated pneumonia rates, potential risk factors, and conservative treatments excluding complete surgical TEP closure. Methods: A systematic review was conducted (1978–2008). A summary risk estimate was calculated using a random-effects meta-analysis model. Results: Twenty-seven peer-reviewed manuscripts were included. The rate of enlarged puncture and/or leakage around the prosthesis was reported in 23 articles (range, 1% to 29%; summary risk estimate, 7.2%; 95% confidence interval [CI], 4.8% to 9.6%). Temporary removal of the prosthesis and TEP- site injections were the most commonly reported conservative treatments. Prosthetic diameter (p =.076) and timing of TEP (p = .297) were analyzed as risk factors; however, radiotherapy variables were inconsistently reported. Conclusions: The overall risk of enlarged puncture seems relatively low, but it remains a rehabilitative challenge. Future research should clearly establish risk factors for enlarged puncture and optimal conservative management.
