Print Collections Management in the Wake of Digitization     

Laurel Ivy Sammonds Reporter  Ross Housewright Presenter 《期刊图书馆员》2013,64(2):193-195

Ross Housewright, a Research Analyst at Ithaka S+R (http://www.ithaka.org/ithaka-s-r/) delivered the keynote address at the E-Resources Symposium at Mississippi State University on September 16, 2010. Housewright challenged traditional thinking about collection and preservation activities in the academic library setting. He introduced two important Ithaka S+R programs—the Faculty Survey and the What to Withdraw Framework—and discussed how they can assist serials librarians struggling to maintain the proper balance between patron needs, budget pressures, and the library's mission to preserve materials in the age of mixed digital and print collections.  相似文献   

Uninterrupted,Sustained, Silent Reading: the rhetoric and the practice     

Chris Robertson  Iris Keating  Lesley Shenton  Ivy Roberts 《Journal of Research in Reading》1996,19(1):25-35

The study investigated whether the rhetoric of uninterrupted, sustained, silent reading (USSR/ERIC) was evident in primary classrooms where the practice was professed to operate. Nine primary schools in three different counties were surveyed, and the sample included both urban and rural schools. Structured interviews were undertaken with the headteacher and two members of staff in each school, followed by classroom observations, focusing on what do teachers do in practice during USSR/ERIC. From both interviews and observations it was evident that teacher interpretation of how the sessions should be organised and managed was not specifically that of the rhetoric, with only one school closely following the prescribed model. Whilst the value of a quiet reading time was generally acknowledged and much good practice observed in sessions, it would appear that many models which operate under the guise of ‘uninterrupted sustained silent reading’ are governed by teacher preference or pupil need.  相似文献   

Foundations of children’s self-concepts about everyday activities: Identities and comparative contexts     

Laurel Fisher 《European Journal of Psychology of Education - EJPE》2014,29(3):537-555

Children’s motivations to engage in everyday activities draw on their experiences in thinking of oneself and the activities. In theory, these personal and social realities provide the complex foundations of self-concepts. The aim of this project was to define the foundations of children’s self-concepts about everyday activities; to focus on everyday activities of literacy and numeracy. Participants were 8- to 12-year-old girls and boys, in a pilot study (N?=?16), correlational models of identities (N?=?297) and comparative contexts (N?=?42), and experimental evidence (N?=?82). The pilot study validated materials, and Study 1 confirmed a perceptual base for self-concepts. Results of Study 2 highlighted a range of comparative contexts, and Study 3 confirmed personal and social bases of children’s self-concepts. In this situation, foundations of self-concepts cover identities (as a sense of individuality and belonging) and self-categorizations, in thinking about stability of skills and abilities over time, and in relation to children the same age. These ideas are readily applied to identities and arrays of self-categorizations in other situations. In conclusion, a personal and social theory of self-concepts extends contemporary Motivational Spiral Models that relate self-concepts to task strategies, skills, feelings and participation. Outcomes suggest foundations for differential interventions motivating children to participate in everyday activities.  相似文献

Carbohydrates and fat for training and recovery     

Louise M Burke  Bente Kiens  John L Ivy 《Journal of sports sciences》2013,31(1):15-30

An important goal of the athlete's everyday diet is to provide the muscle with substrates to fuel the training programme that will achieve optimal adaptation for performance enhancements. In reviewing the scientific literature on post-exercise glycogen storage since 1991, the following guidelines for the training diet are proposed. Athletes should aim to achieve carbohydrate intakes to meet the fuel requirements of their training programme and to optimize restoration of muscle glycogen stores between workouts. General recommendations can be provided, preferably in terms of grams of carbohydrate per kilogram of the athlete's body mass, but should be fine-tuned with individual consideration of total energy needs, specific training needs and feedback from training performance. It is valuable to choose nutrient-rich carbohydrate foods and to add other foods to recovery meals and snacks to provide a good source of protein and other nutrients. These nutrients may assist in other recovery processes and, in the case of protein, may promote additional glycogen recovery when carbohydrate intake is suboptimal or when frequent snacking is not possible. When the period between exercise sessions is <8?h, the athlete should begin carbohydrate intake as soon as practical after the first workout to maximize the effective recovery time between sessions. There may be some advantages in meeting carbohydrate intake targets as a series of snacks during the early recovery phase, but during longer recovery periods (24?h) the athlete should organize the pattern and timing of carbohydrate-rich meals and snacks according to what is practical and comfortable for their individual situation. Carbohydrate-rich foods with a moderate to high glycaemic index provide a readily available source of carbohydrate for muscle glycogen synthesis, and should be the major carbohydrate choices in recovery meals. Although there is new interest in the recovery of intramuscular triglyceride stores between training sessions, there is no evidence that diets which are high in fat and restricted in carbohydrate enhance training.  相似文献   

Confucian Principles: A Study of Chinese Americans’ Interpersonal Relationships in Selected Children’s Picturebooks     

Ivy Haoyin Hsieh 《Children‘s Literature in Education》2018,49(2):216-231

There has not been enough critical analysis of children’s literature by and about Chinese Americans, especially when compared to other minority groups in the United States. In particular, Chinese American historical books lack extensive analysis. It is important to reflect cultural accuracy in literature and to help children develop clear concepts of self and others by providing precise cultural and physical characteristics of people. While cultural authenticity allows children the opportunity to see a reflection of real experiences within a book instead of seeing stereotypes or misrepresentations, obtaining correct information about a certain time period can help children to see images of immigration accurately represented in literature. Using the Confucian delineation of interpersonal relationships as the major criterion of cultural authenticity, this article examines three currently available children’s picturebooks set in the historical period between 1848 and 1885. In addition to exploring how Chinese Americans’ interpersonal relationships are portrayed in these children’s historical books, this article argues for more proactive inclusion of the diversity in selection of picturebooks.  相似文献   

Carbohydrates and fat for training and recovery   总被引：3，自引：0，他引：3

Pediatric health assessments of young children in child welfare by placement type     

Schneiderman JU  Leslie LK  Arnold-Clark JS  McDaniel D  Xie B 《Child abuse & neglect》2011,35(1):29-39

Objectives

To describe health-related problems across placement types (unrelated foster, kin foster, in-home with birth parent); to examine the association of placement and demographic/child welfare variables (child gender, age, race/ethnicity; caregiver language; type of maltreatment, and length of time receiving services from child welfare) with health-related problems.

Methods

This study utilized a retrospective medical chart review of children less than 6 years old (n = 449) seen at an outpatient child welfare pediatric clinic. Logistic regression modeling was used to estimate odds of having a weight, medical, or provisional developmental delay problem by placement and demographic/child welfare characteristics.

Results

Almost 13% of children in the sample were obese (≥95% age-gender specific percentile) and more than a quarter were overweight/obese (≥85%) while only 7% were underweight (≤5%). Most children (78%) had a physical health diagnosis and 25% were provisionally identified with a developmental delay. No differences between weight diagnoses, type of medical diagnoses, and provisional developmental delay by placement type were found, although children with 3 or more medical diagnoses were more likely to be with kin (p < .05). Children 2 years old or older were more likely to be overweight/obese than children under 2 years old (p < .05) and Hispanic children were more likely to be overweight/obese than non-Hispanic children (p < .01). Length of stay in child welfare was positively related with a medical diagnosis or provisional developmental delay (p < .01).

Conclusions

Results argue for careful assessment of weight, medical, and developmental problems in children active to child welfare, whether residing in their home of origin, with kin, or with unrelated foster parents. The increasing problem of obesity among young children in child welfare warrants further investigation and intervention.

Practice implications

The comprehensive health examination and enhanced health maintenance schedule for children in foster care should be extended to children who remain at home with child welfare services as child welfare involvement rather than placement is related to health-related problems.  相似文献   

Tacit models,treasured intuitions and the discrete—continuous interplay     

Ivy Kidron 《Educational Studies in Mathematics》2011,78(1):109-126

We explore conditions for productive synthesis between formal reasoning and intuitive representations through analysis of college students’ understanding of the limit concept in the definition of the derivative. In particular, we compare and contrast cognitive processes that accompany different manifestations of persistence of intuitions and tacit models that coexist with students’ logical reasoning. The students are highly trained in mathematics. We encounter expressions of the persistence and impact of intuitions and tacit pictorial models as described by Fischbein. But we also observe some new characterization of persistence of tacit models in which the tacit pictorial model continues to interfere in the student’s reasoning process, coexists with a logical reasoning but does not prevent the student from reaching a feeling of logical consistency. The empirical analysis and the theoretical discussion offered in the present paper permit us to highlight this very special integration of the formal and the intuitive components of the reasoning process.  相似文献   

Exploring the phase space of a system of differential equations: different mathematical registers     

Thierry Dana-Picard  Ivy Kidron 《International Journal of Science and Mathematics Education》2008,6(4):695-717

We describe and analyze a situation involving symbolic representation and graphical visualization of the solution of a system of two linear differential equations, using a computer algebra system. Symbolic solution and graphical representation complement each other. Graphical representation helps to understand the behavior of the symbolic solution. Together with it, the symbolic solution and its analysis are needed to understand the graphical representation and to overcome the limiting constraints of the CAS. The study described in this paper points out the importance of flexibility in building connections between different mathematical registers, together with the fact that the balance between the usage of symbolic representations and of graphical representations can be very different from one student to the other.
