师范院校普通话教学存在的问题及对策

普通话教学是师范院校大学生教育的一个重要的基础环节,目前尚存在着认识不足、识字量不够、规范读音意识不强、学习方法不够多样、教学方法单一,以及课时设置少、班级相对过大等问题,提出提高认识、增加识字量、增强规范读音意识、学习方法灵活、教学方法多种多样以及增加课时、缩减班级人数等措施,应该引起学生、教师和管理者的高度重视。     

Conditional interval estimation of the mean following rejection of a two sided test

The effect of rejecting a two-sided preliminary test of significance for the mean of a normal distribution upon subsequent interval estimation of the mean is examined. For the case where the variance is known, conditional confidence intervals may be shorter than unconditional intervals, in contrast to the one-sided preliminary test case examined by Meeks and D’Agostino (1983, The American Statistician, 7, 134-136) . For the case where the variance is unknown and must be estimated by the sample variance, it is shown that customary intervals do not offer uniformly greater or lesser coverage than the nominal level.

Conflicting contexts: Midwives’ interpretation of childbirth through photo elicitation

IntroductionThis study seeks to explore midwives’ perceptions about childbirth and in particular their beliefs about normality and risk. In the current climate of increasing interventions during labour, it is important to understand the thought processes that impact on midwifery care in order to examine whether these beliefs influence midwifery clinical decision-making.Method12 Midwives who worked in a variety of metropolitan hospitals in Sydney, Australia were interviewed about how they care for women during labour. The study utilised an inductive qualitative design using photo elicitation during the interview process.ResultsSix themes emerged from the data that clearly indicated midwives felt challenged by working in a system dominated by an obstetric model of care that undermined midwifery autonomy in maintaining normal birth. These themes were: desiring normal, scanning the environment, constructing the context, navigating the way, relinquishing desire and reflecting on reality. Most midwives felt they were unable to practice in the manner they were philosophically aligned to, that is, promoting normal birth, as the medical model restricted their practice.DiscussionThe polarised views of childbirth held by midwives and obstetricians do little to enhance normal birth outcomes. Midwives in this study expressed frustration that they were unable to practice midwifery in a way that reflected their belief in normal birth. This, they cite is a result of the oppressive obstetric model prevalent in maternity care facilities in Sydney and the over use of technological interventions during childbirth.

On the sample characterization criterion for normal distributions

Conventionally, it was shown that the underlying distribution is normal if and only if the sample mean and sample variance from a random sample are independent. This paper focusses on the normal population characterization theorem by showing that, if the joint distribution of a skew normal sample follows certain multivariate skew normal distribution, the sample mean and sample variance are still independent.
