‘Failure to thrive’ revisited

The term ‘non‐organic failure to thrive’ (FTT) has long been used in relation to young children with faltering growth for which no organic cause is found. In this paper, problems arising from dichotomised organic/non‐organic responses to FTT are explored and reasons for the assumption that non‐organic FTT was always due to emotional abuse or neglect are presented. The case is made that, except in a minority of cases, children fail to grow because they consume insufficient calories. Research studies on reasons for poor intake, from factors related to the child and their parents to the wider family and environment, are summarised. Following a brief reference to literature on outcomes, I argue that centile charts should be routinely completed for all young children. If faltering growth is identified, a multi‐factorial assessment should be undertaken. Such an assessment reduces the risk of interventions being based on outdated assumptions about non‐organic FTT and maximises the potential for successful resolution of poor growth. After briefly summarising the literature on interventions, I conclude with suggestions for improving practice in this field, including working in partnership with families and with health and social care professionals already known to them.

The number of records within a random interval of the current record value

LetX ₁,X ₂, … be a sequence of i.i.d. random variables with some continuous distribution functionF. LetX(n) be then-th record value associated with this sequence and μ _n ⁻ , μ _n ⁺ be the variables that count the number of record values belonging to the random intervals(f−(X(n)), X(n)), (X(n), f+(X(n))), wheref−, f+ are two continuous functions satisfyingf−(x)<x, f+(x)>x. Properties of μ _n ⁻ , μ _n ⁺ are studied in the present paper. Some statistical applications connected with these variables are also provided.     

Consistent deconvolution in density estimation

Suppose we have n observations from X = Y + Z, where Z is a noise component with known distribution, and Y has an unknown density f. When the characteristic function of Z is nonzero almost everywhere, we show that it is possible to construct a density estimate f_n such that for all f, Iim_n| |=0.     

Quality Management in Multi‐Level Supply Chains with Outsourced Manufacturing

Outsourcing stretches supply chains longer with added contract manufacturers responsible for the manufacturing of parts and final products. Should a firm change its quality management approach as its supply chain becomes longer with outsourced manufacturing? This paper studies a brand owner's optimal choice between two commonly used quality management approaches: an inspection‐based approach and an external failure‐based approach, in two supply chains – a dyadic supply chain and a multi‐level supply chain where the brand owner outsources manufacturing to an independent contract manufacturer. Our study finds that the brand owner's optimal choice between the two quality management approaches could be opposite in the two supply chains. Specifically, we show that if agency costs exist between the contract manufacturer and the brand owner, the brand owner may prefer an inspection‐based approach in the multi‐level supply chain in contrast to preferring an external failure‐based approach in the dyadic supply chain. In particular, inspections can be effective for the brand owner to limit the manufacturer's profit by excluding defective finished products and components, which in turn reduce agency costs in the multi‐level supply chain. Hence, the efficiency of an inspection‐based approach relative to an external failure‐based approach can be higher in the multi‐level supply chain as compared to the dyadic one. Our findings suggest that firms should adjust to changes in supply chain structures and re‐evaluate the efficiencies of different quality management approaches accordingly.

论清末新政失败的原因及其历史启示

《辛丑条约》签订之后,中国社会陷入了民族危机加深和国内阶级矛盾激化的双重困境,清王朝统治出现了功能性障碍,统治危机进一步加深。为了挽救摇摇欲坠的满清政府,以慈禧太后为首的清政府不得不推行改革,史称清末新政。但是事与愿违,它并没有达到挽救清王朝的目的,反而加速了它的灭亡。清末新政的失败是历史必然性和主体选择错误性互相作用的结果,这启示我们改革要想取得胜利,就必须既合乎规律性,也合乎目的性,在尊重历史必然性的前提下,充分发挥主体选择性。     

中药灌肠治疗慢性肾功能衰竭的疗效观察

目的探讨中药灌肠治疗慢性肾功能衰竭(CRF)的临床疗效。方法将60例CRF患者随机分为2组,每组30例。两组均给予优质低蛋白饮食、降血压、调血脂、降血糖、纠正贫血等一体化治疗,观察组在此基础上予以清肾汤灌肠治疗。比较两组临床疗效及血肌酐(Scr)、尿素氮(BUN)水平。结果观察组总有效率显著高于对照组(P0.05)下同,差异有统计学意义;治疗后,两组Scr、BUN水平均较治疗前明显降低(P0.05或P0.01),但观察组降低幅度更为显著。结论中药灌肠可有效降低CRF患者血Scr和BUN水平,提高临床疗效,值得临床推广应用。     

Complete consistency for the estimator of nonparametric regression models based on extended negatively dependent errors

In this paper, we provide some exponential inequalities for extended negatively dependent (END) random variables. By using these exponential inequalities and the truncated method, we investigate the complete consistency for the estimator of nonparametric regression model based on END errors. As an application, the complete consistency for the nearest neighbour estimator is obtained.
