In recent years, solution‐focused parenting support has been developed and implemented as a promising brief and strength‐based approach. Given the fundamental differences between solution‐focused and the historically more common problem‐focused parenting support and the complexity of transforming professional practice, an actual shift towards solution‐focused parenting support can be expected to be limited up to now. However, because research into the specific communication characteristics of professional parenting support is currently lacking, no conclusion can be drawn at present. Therefore, this study aims to explore the current problem‐ and solution‐focused characteristics of parenting support in the Dutch youth healthcare (YH). In total, 15 support sessions performed by 10 public health nurses were audio recorded and transcribed verbatim. A detailed qualitative content analysis of professional communication was conducted to identify problem‐ and solution‐focused factual, expressive, relational and appealing aspects of parenting support. Problem‐focused characteristics dominated all sessions of parenting support. This study is the first to thoroughly analyse the problem‐focused and solution‐focused communication characteristics of professional parenting support using a qualitative content analysis. Parenting support practice in the Dutch YH did not shift substantially to a solution‐focused approach. More effort is required to stimulate and facilitate this professional transformation.  相似文献

Credit scoring can be defined as the set of statistical models and techniques that help financial institutions in their credit decision makings. In this paper, we consider a coarse classification method based on fused least absolute shrinkage and selection operator (LASSO) penalization. By adopting fused LASSO, one can deal continuous as well as discrete variables in a unified framework. For computational efficiency, we develop a penalization path algorithm. Through numerical examples, we compare the performances of fused LASSO and LASSO with dummy variable coding.  相似文献

以不同生产资料所有制的经营性资产价值量作为衡量主次地位的边界标准,估算第一产业公有制与非公有制的资产规模及其比重变化,并在前人估算的基础上,延伸估算第二和第三产业两种所有制的资产规模及其比重变化。结果发现:截至2012年,中国三次产业经营性总资产约为487.53万亿元,其中公有制经济的资产规模是258.39万亿元,占53%;第二、三产业非公有制经济占增加值和就业规模的比重分别为67.59%和75.20%。这表明,公有制资产仍占主体,非公有制经济贡献占优,中国社会主义基本经济制度充满活力,从而为我国社会主义初级阶段的所有制改革和坚持“两个毫不动摇”的政策提供了理论依据。  相似文献

在当前我国产品设计相对薄弱,企业资金投入不足的情形下,较难自主创新,模仿创新成为产品设计跨越式发展的必经之路。模仿创新相较率先创新具有后发优势,反而能设计出占据市场主导地位和最具经济效益的产品。但模仿创新不是恶劣的伪造,重点在于借鉴改造,从而形成自身风格。  相似文献

The asymptotic variance of the maximum likelihood estimate is proved to decrease when the maximization is restricted to a subspace that contains the true parameter value. Maximum likelihood estimation allows a systematic fitting of covariance models to the sample, which is important in data assimilation. The hierarchical maximum likelihood approach is applied to the spectral diagonal covariance model with different parameterizations of eigenvalue decay, and to the sparse inverse covariance model with specified parameter values on different sets of nonzero entries. It is shown computationally that using smaller sets of parameters can decrease the sampling noise in high dimension substantially.  相似文献

Abstract. We consider the problem of testing parametric assumptions in an inverse regression model with a convolution‐type operator. An L 2 ‐type goodness‐of‐fit test is proposed which compares the distance between a parametric and a non‐parametric estimate of the regression function. Asymptotic normality of the corresponding test statistic is shown under the null hypothesis and under a general non‐parametric alternative with different rates of convergence in both cases. The feasibility of the proposed test is demonstrated by means of a small simulation study. In particular, the power of the test against certain types of alternative is investigated. Finally, an empirical example is provided, in which the proposed methods are applied to the determination of the shape of the luminosity profile of the elliptical galaxy NGC 5017.  相似文献

文章系统解读了楚简《唐虞之道》第14至29号简的思想内涵及脉络,认为这部分简文首先通过尧成为天子之原因的追问,突出了德与位的张力问题,即在应然之理上,有位必当有德,但就实然之事看,有德未必有位.简文对这一德位张力有两个层面的解决方案:一方面,要求有德无位者全力修德,谨守性命,安于时命,养成恒常如一的圆满德行,从而能在得位而治时能“利天下而弗利”;另一方面,要求有位者透悟性命之正,从而能主动尚德授贤、退而养生,这既能使贤者居位而利天下,又能退而养生以自利.简文将“七十致政”之礼普遍化,试图断绝天子终身制的构想,也具有深刻的政治哲学意义.  相似文献

The conventional Shewhart-type control chart is developed essentially on the central limit theorem. Thus, the Shewhart-type control chart performs particularly well when the observed process data come from a near-normal distribution. On the other hand, when the underlying distribution is unknown or non-normal, the sampling distribution of a parameter estimator may not be available theoretically. In this case, the Shewhart-type charts are not available. Thus, in this paper, we propose a parametric bootstrap control chart for monitoring percentiles when process measurements have an inverse Gaussian distribution. Through extensive Monte Carlo simulations, we investigate the behaviour and performance of the proposed bootstrap percentile charts. The average run lengths of the proposed percentage charts are investigated.  相似文献
