In this article, we review a construction in the complex geometry often known as the Penrose transform. We then present two new applications of this transform. One concerns the construction of symmetries of the massless field equations from mathematical physics. The otherconcerns obstructions to the embedding of CR structures on the three-sphere.

BACKGROUND: The inability of paramedics to perform accurate calculations may result in a compromise of patient safety which may result from under or over dosing of drugs, incorrect joules for defibrillation, or a major adverse event such as death. The objective of this study was to identify the drug calculation and mathematical ability of qualified operational ***: The study used a cross-sectional design with a paper-based calculation questionnaire. Twenty paramedics enrolled in an intensive care paramedic course were eligible to participate in the study. The questionnaire consisted of demographic, drug calculation(seven questions), and mathematical(five) questions. Students were given no notice of the impending study and use of a calculator was not ***: All eligible students participated in the study. The average time employed as a paramedic was 7.25 years, SD 2.5 years, range four years to twelve years. Four(20%) students got all 12 questions correct, and five(41.6%) got 50% or less. The average score was 8.6(71.7%) correct, SD 2.8 correct, range 3 to 12 correct questions. There were eight(40%) conceptual errors, 12(60%) arithmetical errors, and five(25%) computational ***: The results from this study supports similar international studies where paramedic's ability to undertake mathematical and drug calculations without a calculator varies, with some results highlighting the paramedics mathematical skills as a potential risk to patient safety. These results highlight the need for regular continuing mathematical and drug calculation practice and education to ensure a lower error rate.

F rankle Dunn (Clint eastwood) has trained and managed some incredible fighters during a life time spent in the ring. He is a professional boxing trainer and owner of The Hit Pit, an old-school boxing gym nestled in the gritty heart of downtown Los Angeles. The Hit Pit is Frankie’s life, and he divides his time between the seemingly disparate activities of training fighters and attending mass -which he has done almost every day for the past 23 years. Unable to forgive himself for becoming estranged from his daughter long ago, he sends her a letter every week, and the

Previous investigation of drug calculation skills of qualified paramedics has highlighted poor mathematical ability with no published studies having been undertaken on undergraduate paramedics. There are three major error classifications. Conceptual errors involve an inability to formulate an equation from information given, arithmetical errors involve an inability to operate a given equation, and finally computation errors are simple errors of addition, subtraction, division and multiplication. The objective of this study was to determine if undergraduate paramedics at a large Australia university could accurately perform common drug calculations and basic mathematical equations normally required in the workplace. A cross-sectional study methodology using a paper-based questionnaire was administered to undergraduate paramedic students to collect demographical data, student attitudes regarding their drug calculation performance, and answers to a series of basic mathematical and drug calculation questions. Ethics approval was granted. The mean score of correct answers was 39.5% with one student scoring 100%, 3.3% of students （n=3） scoring greater than 90%, and 63% （n=58） scoring 50% or less, despite 62% （n=57） of the students stating they ＇did not have any drug calculations issues＇. On average those who completed a minimum of year 12 Specialist Maths achieved scores over 50%. Conceptual errors made up 48.5%, arithmetical 31.1 % and computational 17.4%. This study suggests undergraduate paramedics have deficiencies in performing accurate calculations, with conceptual errors indicating a fundamental lack of mathematical understanding. The results suggest an unacceptable level of mathematical competence to practice safely in the unpredictable prehospital environment.

本文首先对中国的儿童营养不良不平等的集中度指数分析方法进行了简单的描述,然后选取“不同年龄段的身高Z评分”(Heightforagezscore)作为衡量指标。根据中国9个省份的家庭调查数据,我们发现人均家庭收入、户主受教育程度、城镇户口以及公交的便利程度都有助于降低儿童营养不良程度,儿童年龄对营养不良状况具有非线性影响。而城乡差距、省份差异和户主受教育程度的不平等,则会加剧营养不良不平等。另外,本文发现性别对营养不良及其不平等都没有影响。据此,本文建议,为改善中国儿童营养不良的不平等状况,中国政府应当进行相应的基础设施及社会福利项目投资。
