Graduate Student Space and Service Needs: A Recommendation for a Cross-campus Solution     

Hannah Gascho Rempel  Uta Hussong-Christian  Margaret Mellinger 《The Journal of Academic Librarianship》2011,37(6):480-487

Focus group methodology was used to investigate graduate students' cross-campus technology, space and service needs. Although the library provides valued services and spaces, graduate students need enhanced and more equitable support for their roles as teachers and scholars. Librarians can provide leadership and act as advocates for graduate student needs in partnership with other campus stakeholders.  相似文献   

Identifying the genealogical self     

Hannah Little 《Archival Science》2011,11(3-4):241-252

What is the connection between archives and identity? One of the main user groups of archives are family historians who often state that they undertake to find out about their ancestry in order to ??find out who they are??. But what does such a claim mean, where did it come from and what is the role of archives in this search for the self? This article explores these questions by examining two modern genealogical texts: Alex Haley??s Roots (1976) and the television programme, Who Do You Think You Are? (2004). These narratives show that archives can be part of the articulation of the self and that they have the potential to disclose the who beyond the private confines of the family to the reader or television audience. In this way, the archive has become a theatre of meaning, memory and self-identity, a performative space in which identities are enacted. The paper concludes by arguing that the connection between archives and identity can be a complex-layered performance that not only articulates the self but also has the potential to connect the self to the other. Such an exploration of the imaginative and performative aspects of archives within such genealogical storytelling is important if we are to further our understanding of the role of archives in contemporary Western society.  相似文献

The Home Literacy Environment and Preschool Children's Reading Skills and Interest     

Lay See Yeo  Winston W. Ong  Charis M. Ng 《Early education and development》2014,25(6):791-814

Research Findings: This study explored the association between the home literacy environment (HLE), conceptualized as comprising parents’ reading beliefs and home literacy practices, and preschoolers’ reading skills and reading interest. It also identified factors in the HLE that predict emerging reading competence and motivation to read. A total of 193 children age 6 years from 14 preschools across Singapore and their parents participated in the study. The parents completed a reading belief inventory, a family literacy activity inventory, and a demographic questionnaire that surveyed the child's reading interest. The children were administered a battery of standardized literacy tests. The study found a moderate relationship between the HLE and children's reading competencies and a strong relationship between the HLE and children's reading interest. When parents’ education level and children's age were controlled, hierarchical multiple regression analyses found that family literacy activities contributed more unique variance to children's reading outcomes and reading interest than did parents’ reading beliefs. Active parental involvement was the strongest component of the HLE, with parent–child engagement in reading and writing emerging as the best predictor of both the child's emerging reading skills and reading interest. With respect to reading beliefs, parents’ efficacy in supporting literacy development before their child attended school positively predicted reading competence, as did parents’ affect and verbal participation in fostering reading interest. However, verbal participation negatively predicted Singapore children's reading competence. Practice or Policy: The implications of the results were discussed.  相似文献   

Therapeutic radionuclides in nuclear medicine: current and future prospects     

Chai-Hong Yeong  Mu-hua Cheng  Kwan-Hoong Ng 《Journal of Zhejiang University. Science. B》2014,15(10):845-863

The potential use of radionuclides in therapy has been recognized for many decades. A number of radionuclides, such as iodine-131 (¹³¹I), phosphorous-32 (³²P), strontium-90 (⁹⁰Sr), and yttrium-90 (⁹⁰Y), have been used successfully for the treatment of many benign and malignant disorders. Recently, the rapid growth of this branch of nuclear medicine has been stimulated by the introduction of a number of new radionuclides and radiopharmaceuticals for the treatment of metastatic bone pain and neuroendocrine and other malignant or non-malignant tumours. Today, the field of radionuclide therapy is enjoying an exciting phase and is poised for greater growth and development in the coming years. For example, in Asia, the high prevalence of thyroid and liver diseases has prompted many novel developments and clinical trials using targeted radionuclide therapy. This paper reviews the characteristics and clinical applications of the commonly available therapeutic radionuclides, as well as the problems and issues involved in translating novel radionuclides into clinical therapies.  相似文献   

Vertical microbubble column–A photonic lab-on-chip for cultivation and online analysis of yeast cell cultures     

Stefanie Demming  Gena Peterat  Andreu Llobera  Hannah Schmolke  Alexander Bruns  Michael Kohlstedt  Ala‘aldeen Al-Halhouli  Claus-Peter Klages  Rainer Krull  Stephanus Büttgenbach 《Biomicrofluidics》2012,6(3)

This paper presents a vertically positioned microfluidic system made of poly(dimethylsiloxane) (PDMS) and glass, which can be applied as a microbubble column (μBC) for biotechnological screening in suspension. In this μBC, microbubbles are produced in a cultivation chamber through an integrated nozzle structure. Thus, homogeneous suspension of biomass is achieved in the cultivation chamber without requiring additional mixing elements. Moreover, blockage due to produced carbon dioxide by the microorganisms—a problem predominant in common, horizontally positioned microbioreactors (MBRs)—is avoided, as the gas bubbles are released by buoyancy at the upper part of the microsystem. The patterned PDMS layer is based on an optimized two-lithographic process. Since the naturally hydrophobic PDMS causes problems for the sufficient production of microbubbles, a method based on polyelectrolyte multilayers is applied in order to allow continuous hydrophilization of the already bonded PDMS-glass-system. The μBC comprises various microelements, including stabilization of temperature, control of continuous bubble formation, and two optical configurations for measurement of optical density with two different sensitivities. In addition, the simple and robust application and handling of the μBC is achieved via a custom-made modular plug-in adapter. To validate the scalability from laboratory scale to microscale, and thus to demonstrate the successful application of the μBC as a screening instrument, a batch cultivation of Saccharomyces cerevisiae is performed in the μBC and compared to shake flask cultivation. Monitoring of the biomass growth in the μBC with the integrated online analytics resulted in a specific growth rate of 0.32 h⁻¹, which is almost identical to the one achieved in the shake flask cultivation (0.31 h⁻¹). Therefore, the validity of the μBC as an alternative screening tool compared to other conventional laboratory scale systems in bioprocess development is proven. In addition, vertically positioned microbioreactors show high potential in comparison to conventional screening tools, since they allow for high density of integrated online analytics and therefore minimize time and cost for screening and guarantee improved control and analysis of cultivation parameters.  相似文献

School‐to‐work transition services for students with disabilities in Malaysia: organisations' views on policy and practices     

Melissa Ng Lee Yen Abdullah  See Ching Mey  Tan Kok Eng  Rosly Othman  Ahmad Fairuz Omar 《Journal of Research in Special Educational Needs》2013,13(4):259-271

Transition services are required by law for students with disabilities in many developed countries. In Malaysia, however, there is still no specific legislation mandating that school‐to‐work transition planning and services be provided to students with disabilities. This study investigated the state of the transition services provided by educational organisations to students with disabilities in Malaysia. A mixed method research design, which utilises both quantitative and qualitative research techniques, was employed to obtain information from 23 government organisations and NGOs involved in the education and training of students with disabilities. This study found that the organisations surveyed were aware of the lack of transition support and call attention to the importance of instituting a national policy on school‐to‐work transition services and supported employment systems for students with disabilities. The legislative and educational implications for Malaysia are discussed.  相似文献   

Developing Singapore school leaders to handle complexity in times of uncertainty     

Pak Tee Ng 《Asia Pacific Education Review》2013,14(1):67-73

In times of uncertainty, university faculties have a duty to prepare school leaders to handle complexity, as the number of variables in the educational system and the interactivity of variables increase exponentially. The Leaders in Education Program (LEP) is a 6-month full-time program at the Singapore National Institute of Education (NIE, which is a part of Nanyang Technological University). The LEP aims to prepare especially selected vice-principals and ministry officers in Singapore for school leadership. The LEP is a collaborative effort between the NIE and the Ministry of Education, an example of a university–government partnership in program development. This article describes the efforts of the LEP in developing the ability of school leaders to deal with complexity. It also examines in detail one particular component of the LEP, the Creative Action Project, to illustrate how this is done in practice, and analyzes the views of participants on their learning through the project.  相似文献
