Subject Access for a Culinary Collection: Experiments at the Longone Center for American Culinary Research

ABSTRACT

A collection of culinary and related materials at the William L. Clements Library has potential uses beyond the niche of culinary history, expanding into and beyond the emerging interdiscipline of food studies. The library is considering other holdings for related content. Such collections are inadequately served by existing subject access. Experiments with plentiful subject access are being tried, including an unusual use of MARC records for ephemera, a database recording mentions of food-related phenomena in Civil War correspondence, and experimentation with a controlled vocabulary. These experiments have drawn on a “community of interest,” including subject specialists and volunteer docents.     

力克斯兔被毛细度,粗毛度和皮板厚度研究

于冬（１２月下旬－１月上旬）夏（６月下旬－７月上旬）两季分别随机选取１－６月龄的美系獭兔各５只，屠杀后取皮，自然伸展后晾皮，待其干燥后分别取样测定不同部位的被毛粗毛率、细度和皮板厚度。结果表明，美系獭兔的被毛粗毛率平均为５．４９％；被毛细度平均为１６．３３μｍ；４、５、６月龄獭兔皮板厚度分别为０．５０ｍｍ、０．５７ｍｍ和０．６５ｍｍ。三项指标在不同部位、季节和月龄等方面均有一定的变化，而背的中部具     

What criteria are relevant for predicting the invasive capacity of a new agricultural weed? The case of invasive American species in France

In Europe, exotic species are assessed for their potential threat only after they have already become weeds. To test hypotheses underlying risk assessment procedures, 274 North and South American exotic species naturalized in France were compared to differentiate environmental from agricultural weeds and to characterize weeds of several crops. Most agricultural exotic weeds belonged to the Asteraceae and the Poaceae, but proportionally to the total number of invasive species from a family the most successful families were the Amaranthaceae, Euphorbiaceae and Poaceae. Weed status in North and South America was the best predictor of agricultural weed status in France, and a pre-1900 date of introduction was associated with a greater likelihood of having become a major weed. The characteristics of 78 species present in field crops were examined in relation to management practices. In annual crops, the life-cycle compatibility of weeds appeared to be the main factor of selection. Exotic species differed in their C4 photosynthesis pathway in maize and rice. In vineyards, many ecological strategies are possible because the habitat is heterogeneous. Intrageneric comparison of exotic and native species showed a superior relative growth rate and higher biomass production under nutrient-rich conditions for exotics. However, it is still difficult to find a predictive function that fits well with all observed cases of weed invasion.     

输出立场与美学立场在高校英美文学课程中的应用

本论文以罗森布莱特的读者反应理论为参照,通过在实际教学中的调查数据,探究以下问题:教师在课堂上使用美学式教学和输出式教学分别对学生的学习动力以及学生对文学作品的理解会产生什么样的影响;在高校英美文学的教学中,教师应如何有效地利用美学式教学和输出式教学。     

海拔和肥料互作对美引烤烟品种经济性状的影响

以美引品种NC196和NC471为材料,研究了不同海拔高度（1 489 m和1 883 m）和肥料水平对其主要经济性状的影响。结果表明：NC196对海拔高度较敏感,而NC471对肥料较敏感;2个美引品种在低海拔烟区种植的均价、上等烟比例均高于高海拔烟区;NC196在低海拔的中、高肥力水平条件下栽培,经济性状相对较好,NC471在高肥力水平条件下栽培,经济性状相对较好。     

基于ACSI模型的景区游客满意度研究——以南宁市“花花大世界”景区为例

根据美国消费者满意指数模型,结合南宁"花花大世界"景点景区的特点构建其游客满意度测评指标体系,通过问卷、李克特量表法和SPSS数据统计方法定量分析了"花花大世界"游客满意度情况。得出结论:学生、家庭和企事业单位是"花花大世界"的主要游客,其总体满意度偏低,环境卫生质量感知普遍较差,对"花花大世界"内销售的产品满意度较差。在此基础上提出相应对策。     

4个美国李品种在沾益的引种成效

2000年沾益县自山东农学院果树研究所引入美国大红玫瑰、碧绿红心、美蓝宝石、卡特丽娜4个李品种试种。经过4年的栽培试验，评选出生长好、抗性强，具有丰产、稳产、晚熟性能，果大、质优商品性状好，适宜在沾益及相似生态区域栽培的大红玫瑰、碧绿红心、美蓝宝石3个李品种。     

不同加工类型原皮西洋参的电子显微分析

对不同加工类型的原皮西洋参进行隧道电镜扫描、分析,研究结果表明：冷冻干燥、真空干燥的产品内部结构良好，淀粉粒、树脂道、草酸钙晶体等微观结构清晰可辨；传统烘房干燥的正常参也具有良好的内部结构；但是，微波干燥、传统烘房干燥的不正常参．如褐变参、青枝等于制品．干燥过程中其内部结构已被破坏．产品的内外结构均不符合商品要求。因此，可以利用电镜显微分析对西洋参的干制品质量进行分析、判断，评价产品的优劣。     

美国山核桃主要栽培品种的RAPD鉴定

以叶片为材料,采用改良CTAB法和16种Operon引物对从原产地美国引进的30个美国山核桃主要栽培品种进行RAPD分子分析。结果表明：参试品种问存在明显的基因带型差异,多态型比率高达78．1％;根据RAPD特异分离谱带确定了各品种的标记基因型．以此可实现对美国山核桃无性系品种DNA水平上的鉴别;以标记基因型对30个美国山核桃品种进行系统聚类,结果与传统形态学及Marquard等人的同工酶分类基本吻合。
