Finding an appropriate temporary storage location for books and providing access to them is a significant challenge for libraries undergoing renovations. The current article describes the use of a document management company by an academic library to store 430,000 books for 8 months and provide a retrieval-on-demand service. Aspects covered include the selection of a commercial storage provider with its own retrieval service; details of the move to and from offsite storage; the integration of the service with library processes; communications and user feedback; book usage during the storage period; overall costs; and lessons learned from the experience. 相似文献

The combined effects of pH and temperature on red pigment production and fungal morphology were evaluated in a submerged culture
of Penicillium purpurogenum GH2, using Czapek-Dox media with d-xylose as a carbon source. An experimental design with a factorial fix was used: three pH values (5, 7, and 9) and two temperature
levels (24 and 34 °C) were evaluated. The highest production of red pigment (2.46 g/L) was reached with a pH value of 5 and
a temperature of 24 °C. Biomass and red pigment production were not directly associated. This study demonstrates that P. purpurogenum GH2 produces a pigment of potential interest to the food industry. It also shows the feasibility of producing and obtaining
natural water-soluble pigments for potential use in food industries. A strong combined effect (p<0.05) of pH and temperature was associated with maximal red pigment production (2.46 g/L). 相似文献

利用中国健康与营养调查(CHNS)数据,本研究对农村父母外出务工与留守子女初、高中阶段辍学行为之间的关系进行了实证分析。结果表明:父亲外出务工会显著降低留守子女初、高中阶段的辍学概率,母亲外出务工则会显著增加留守子女初中阶段的辍学概率。此外,免费义务教育政策的实施在较大程度上降低了留守子女的初、高中阶段的辍学概率;与那些父母受教育程度较低的留守子女相比,父母受教育程度越高的留守子女越不容易辍学;家庭子女数和机会成本会提高留守子女初中阶段辍学的概率。因此,为降低农村中学阶段子女辍学率,政府应当增加农村妇女当地就业机会以减少母亲外出的影响、推进户籍制度改革使随迁子女能获得同等的教育机会,并为高中阶段和多子女家庭提供教育补贴。 相似文献

This study investigated development of the Big Five personality traits from early childhood into adulthood. An initial group of 137 Swedish children were assessed eight times between ages 2 and 29 years. Initial decreases in extraversion leveled off in early adulthood; agreeableness and conscientiousness increased from ages 2 to 29; neuroticism initially increased, leveled off in later childhood and adolescence, and decreased throughout early adulthood; while openness to experience showed an initial increase, then decreased and leveled off in early adulthood. Individual developmental trajectories varied significantly, particularly in relation to gender. Personality traits became increasingly stable, and the fact that childhood scores predicted scores in adulthood indicated that personalities are fairly stable across this portion of the life span. 相似文献

Based on a qualitative study involving 124 professional and managerial class families in Catalonia (Spain), this paper describes the aims and objectives these families have for the education of their children. During the fieldwork, when asked what they were aiming for in the education of their children, almost all of the parents replied ‘for them to be happy’. But what kind of happiness are they talking about? What kind of education might lead to happiness? Drawing principally on the work of Kellerhals and Montandon and their ‘contractual model of education’ and Bauman’s concepts of ‘secondary security’ and ‘homo eligens’, although also taking into account the related contributions of Lareau, Vincent and Ball, Stefansen and Aarseth, and Kusserow, the paper aims to demonstrate the strong connection these families make between happiness and ‘absolute’ autonomy, understood as two sides of the same coin and seen, by the participants, as the guiding principle that should shape the way they bring their children up. 相似文献

The aim of the study was to investigate progress in reasoning capacity and knowledge base appraisal in a longitudinal analysis of data from summative evaluation throughout a medical problem-based learning curriculum. The scores in multidisciplinary discussion of a clinical case and multiple choice questionnaires (MCQs) were studied longitudinally for 213 students from years 2 to 5. The capacity of core knowledge delimitation was calculated as the difference between the levels of average ascertainment degrees given for correct and incorrect answers at MCQ. For both multidisciplinary discussion of a clinical case evaluation and self-estimation of core knowledge, the capacity increases throughout the curriculum. The reasoning capacity assessed through multidisciplinary discussion of a clinical case is positively correlated with MCQ scores and the capacity to discriminate the mastered core knowledge. In conclusion, this study indicates that self-estimation of core knowledge is associated with an increase in reasoning performance through a well-organised knowledge base. Since that ability is related to success or failure, it is suggested that student awareness about delimitation of mastered core knowledge is considered as part of learning. 相似文献
