Apollo 15 main-parachute failure

In the investigation of the failure of one of the three main parachutes of the Apollo 15 spacecraft, which collapsed at approximately 1825 meters after operating properly from deployment at 3050 meters, three conditions considered to be possible causes of the failure were produced. The suspect conditions were the proximity of the forward heat shield that passed the spacecraft at approximately 1825 meters, the dumping of the reaction control system hypergolic propellants at approximately 1825 meters, and the failing of a riser link found on a recovered parachute. (The failed parachute was not recovered). The remaining two parachutes functioned as planned and averted a catastrophic failure. The conclusions concerning the cause of the failure are discussed

Is the U.S. Unemployment Rate Today Already as High as It Was in 1982?

In 1982, the United States experienced the highest annual unemployment rate since the Great Depression -- 9.7 percent. In principle, that rate is directly comparable to the 8.1 percent seasonally adjusted unemployment rate for February 2009, and suggests that current unemployment is still not as bad as it was in 1982.The official unemployment rate, however, masks two important differences between the unemployment rate in 1982 and today. The first difference is demographic. In 1982, the US population was substantially younger than it is today. Even in an otherwise identical economy, we would expect a younger population to have a higher unemployment rate than an older population would. The second difference is statistical. The main government survey used to measure the unemployment rate -- the Current Population Survey (CPS) reaches a smaller share of the population today than it did in 1982, and is especially likely to miss people who are not employed. As a result, the official unemployment rate understates the unemployment rate relative to 1982

Parental Perceptions of the Management of Childern with Type 1 Diabetes at School: A Broader Perspective

The purpose of this study was to examine parental perceptions related to the care and management of children with Type 1 diabetes at school. Parents of elementary and middle school-age children with Type 1 diabetes completed a survey questionnaire, which included one open-ended question. The questionnaire was developed by the researchers based on original questionnaires by Nabors, Lehmkuhl, Christos, and Andreone (2003) and Lewis, Powers, Goodenough and Poth (2003 ). Permission to use and modify the questionnaires was provided by Nabors and Poth. Results from this study showed a split in parental satisfaction regarding care provided by school personnel in the following areas: level of knowledge and skills on diabetes, ability to handle a hypoglycemic episode, communication between parents and school, and accommodation in meeting the needs of the child at school. The majority of parents offered suggestions for school nurses and school personnel regarding the care of children with diabetes. Suggestions included the need for training and education, more support, and better communication. Findings from this study provide evidence to support specific content for educating school staff, a greater presence of licensed personnel, and more open communication between families and school personnel

Gender Differences in Non-Suicidal Self-Injury in a Sample of Treatment-Seeking Gamblers

Gambling Disorder (GD) is a public health concern with tremendous implications (Smith & Wynne, 2002). The disorder rarely occurs in isolation, often presenting with other conditions. Suicidal ideation and attempts are common among treatment-seeking gamblers (Maccallum & Blaszczynski, 2003). An important yet overlooked risk factor for suicidality is non-suicidal self-injury (NSSI; Klonsky et al., 2013). NSSI can serve many functions: relief of negative emotions; generation of positive states; escape from interpersonal obligations; attention or facilitation of resources (Nock & Prinstein, 2004). Previous research has found gender differences in NSSI. Despite NSSI’s relationship to suicidality and the noted gender differences, literature on gender differences within a gambling population is scarce. Therefore, we investigated gender differences in the form and function of NSSI in a clinical sample of 364 treatment-seeking gamblers. Overall, results suggest that females engaged in more hair pulling. Further, females endorsed often engaging in NSSI for the relief of negative emotions and for attention or facilitation of resources. Understanding gender differences in the form and functions of NSSI can provide insight into appropriate prevention, intervention, and treatment opportunities. Importantly, given the relationship of NSSI to suicide, understanding differences in NSSI may inform intervention efforts for this vulnerable population
