三亚市天涯镇耕地土壤养分状况分析

借助三亚市推行测土配方施肥项目,对三亚市天涯镇的耕地土壤进行随机分布取样,分析土壤中的养分状况.根据海南省土壤养分含量分级标准,天涯镇188个样本数据结果显示:三亚市天涯镇的耕地土壤多为酸性,pH值多在4.6-5.6范围内;有机质的含量总体上在中等水平,处于三、四级,最多分布在10-20g/kg范围内;碱解氮的含量普遍较为缺乏,多处于三、四级,即在61-120mg/kg之间;速效磷的含量较为丰富,一、二级较多,含量多在11mg/kg以上;速效钾的含量较为缺乏,多处于四至六级,多分布在100mg/kg以下.

Evaluation of a pilot programme and a follow-up study of infant feeding practices during the scaled-up programme in Botswana

This paper describes the results of two studies concerning a programme to prevent mother-to-child transmission of HIV in Botswana. The programme included VCT, provision of oral AZT to the HIV infected mothers and to the infant, infant feeding counselling and support, and free provision of formula for infants of HIV infected mothers who opted not to breastfeed. The study evaluating the pilot phase of the programme concluded that the programme should be scaled up. After the programme expanded, a follow-up evaluation of infant feeding practices was conducted. Infant feeding practices differed significantly between intervention and non-intervention sites and between mothers of unknown HIV status, non-infected mothers and HIV-infected mothers. Among the infected mothers who chose exclusive formula feeding, 96% maintained this up to the time of interview. Health workers' knowledge about HIV transmission was weak. Counselling on feeding needs to be improved in many areas.     

拓展基尼系数及其居民消费应用研究

本文给出了拓展基尼系数的一个等价定义,给出拓展基尼系数组群、要素分解的统一形式。对2009年我国城乡居民食品消费数据进行结构性分析,结果表明：⑴拓展基尼系数是不平等厌恶参数的增函数,最小值为0、最大值为1-S1/p1;⑵随着不平等厌恶参数的增大,各个组群或要素对不平等边际效应的方向保持相对稳定;⑶城镇居民在外餐饮、肉禽及制品、水产品类支出份额的增加,对食品消费不平等产生消极的边际影响。     

Mothers’ attitudes and beliefs about infant feeding highlight barriers to exclusive breastfeeding in American Samoa

BackgroundIn American Samoa, initiation of breastfeeding is almost universal but exclusive breastfeeding, a promising target for obesity prevention, is short in duration.Aims(1) To examine American Samoan mothers’ feeding experiences and attitudes and beliefs about infant feeding and (2) to identify potential barriers to exclusive breastfeeding.MethodsEighteen semi-structured interviews were conducted with American Samoan mothers at 16–32 days postpartum. Interviews focused on mother's knowledge and beliefs about infant feeding, how their infants were fed, why the mother had chosen this mode of infant feeding, and how decisions about feeding were made within her social surroundings. A thematic qualitative analysis was conducted to identify salient themes in the data.FindingsIntention to exclusively breastfeed did not predict practice; most women supplemented with formula despite intending to exclusively breastfeed. The benefits of breastfeeding were well-recognized, but the importance of exclusivity was missed. Formula-use was not preferred but considered an innocuous “back-up option” where breastfeeding was not possible or not sufficient for infant satiety. Identified barriers to exclusive breastfeeding included: the convenience of formula; perceptions among mothers that they were not producing enough breast milk; and pain while breastfeeding. The important support role of family for infant feeding could be utilized in intervention design.ConclusionThis study identified barriers to exclusive breastfeeding that can be immediately addressed by providers of breastfeeding support services. Further research is needed to address the common perception of insufficient milk in this setting.
