Microscopy and literature     

Peter J.F. Harris 《Endeavour》2019,43(3):100695

This article draws attention to literary works which have been influenced by microscopy, or in which microscopy has played a significant role. The work of writers including Jonathan Swift, Voltaire, George Eliot, H. G. Wells and D. H. Lawrence is discussed. In many cases these authors had direct experience of operating microscopes and viewing the wonders of the microscopic world. However, with the increasing separation of the two cultures, recent examples of microscopy in literature are rare.  相似文献   

When multi-functional landscape meets Critical Zone science: advancing multi-disciplinary research for sustainable human well-being     

Ying Luo  Yihe Lü  Bojie Fu  Paul Harris  Lianhai Wu  Alexis Comber 《国家科学评论(英文版)》2019,6(2):349

Environmental degradation has become one of the major obstacles to sustainable development and human well-being internationally. Scientific efforts are being made to understand the mechanism of environmental degradation and sustainability. Critical Zone (CZ) science and research on the multi-functional landscape are emerging fields in Earth science that can contribute to such scientific efforts. This paper reviews the progress, similarities and current status of these two scientific research fields, and identifies a number of opportunities for their synergistic integration through functional and multi-functional approaches, process-based monitoring, mechanistic analyses and dynamic modeling, global long-term and networked monitoring and systematic modeling supported by scaling and deep coupling. These approaches proposed in this paper have the potential to support sustainable human well-being by strengthening a functional orientation that consolidates multi-functional landscape research and CZ science. This is a key challenge for sustainable development and human well-being in the twenty-first century.  相似文献   

The current state of human performance technology: A citation network analysis of Performance Improvement Quarterly, 1988–2010     

Yonjoo Cho  Sung Jun Jo  Sunyoung Park  Ingu Kang  Zengguan Chen 《Performance Improvement Quarterly》2011,24(1):69-95

This study conducted a citation network analysis (CNA) of human performance technology (HPT) to examine its current state of the field. Previous reviews of the field have used traditional research methods, such as content analysis, survey, Delphi, and citation analysis. The distinctive features of CNA come from using a social network analysis approach to see relational and network patterns in the citation data. This CNA found that the Performance Improvement Quarterly network showed more widely but loosely connected and less centralized structural attributes than the human resource development network; the 10 most influential articles in the field were identified; frequently co‐cited articles were recognized as having a strong relationship by subsequent researchers; and five cohesive subgroups showed key topics in the field (performance, instructional design, performance support, organization/workplace, and transfer of training). Implications from the results of the CNA were elaborated on for future research in HPT.  相似文献   

The Ultimate Survey: Asking One Question at a Time to Get Feedback from Library Users     

Leticia Camacho  Brian Wages  Taylor Harris 《The Reference Librarian》2020,61(1):1-14

ABSTRACT

Libraries use surveys and other instruments to gather feedback from their users. However, with competition from many other campus entities requesting input, how can survey fatigue be avoided? To gather this feedback, the Social Sciences Reference Desk utilized a short, fun and easy method. Each week for 10 weeks during the fall semester of 2017, the reference assistants wrote a survey question on a whiteboard and provided sticky notes for patrons to write their answers. The survey provided valuable information about patrons’ needs and expectations. It also fostered changes that were easily implemented to improve the delivery of library services.  相似文献   

A New Student Learning Focus for the Academic Library: From Geographical Proximity of the Learning Commons to Organizational Proximity within the Library     

Jo Ann F. Murphy 《图书馆管理杂志》2017,57(7):742-757

In 2015, student learning programs at the University of Saskatchewan moved organizationally to the university library. While these services resided physically in the library as part of the Learning Commons partnership, this recent change presents the library with a new focus and responsibility for broader student learning support and academic skill development. Highlighting examples of organizational integration of student learning support, this article uses a proximity perspective, suggesting that geographical proximity of services in the learning commons does not go far enough to achieve the deeper collaboration and integration necessary for holistic and integrated learning, and that organizational proximity is needed.  相似文献

Cytocompatible cellulose nanofibers from invasive plant species Agave americana L. and Ricinus communis L.: a renewable green source of highly crystalline nanocellulose     

Evdokimova  Olga L.  Alves  Carla S.  Krsmanović Whiffen  Radenka M.  Ortega  Zaida  Tomás  Helena  Rodrigues  João 《Journal of Zhejiang University. Science. B》2021,22(6):450-461

In this study, the fibers of invasive species Agave americana L. and Ricinus communis L. were successfully used for the first time as new sources to produce cytocompatible and highly crystalline cellulose nanofibers. Cellulose nanofibers were obtained by two methods, based on either alkaline or acid hydrolysis. The morphology, chemical composition, and crystallinity of the obtained materials were characterized by scanning electron microscopy(SEM) together with energy-dispersive X-ray spectroscopy(EDX), dynamic light scattering(DLS), X-ray diffraction(XRD), and Fourier transform infrared(FTIR)spectroscopy. The crystallinity indexes(CIs) of the cellulose nanofibers extracted from A. americana and R. communis were very high(94.1% and 92.7%, respectively). Biological studies evaluating the cytotoxic effects of the prepared cellulose nanofibers on human embryonic kidney 293 T(HEK293 T) cells were also performed. The nanofibers obtained using the two different extraction methods were all shown to be cytocompatible in the concentration range assayed(i.e., 0-500 μg/mL). Our results showed that the nanocellulose extracted from A. americana and R. communis fibers has high potential as a new renewable green source of highly crystalline cellulose-based cytocompatible nanomaterials for biomedical applications.  相似文献

Self-regulated strategy development in writing: Going beyond NLEs to a more balanced approach     

Karen R. Harris  Tanya Santangelo  Steve Graham 《Instructional Science》2008,36(5-6):395-408

In this article, we present an argument for consideration by those researching and promoting new learning environments (NLEs). We believe advocates of NLEs should consider the literature and research base indicating effective instruction is not based on a forced dichotomy between theoretical perspectives, but rather a thoughtful, pragmatic blending of practices based on evidence gained from various perspectives and lines of research. While unguided or minimally guided instructional approaches are popular and intuitively appealing, these approaches ignore substantial evidence indicating these approaches are less effective and less efficient than instructional approaches that incorporate guidance of the learning process that is faded as internal guidance is developed (Kirschner et al., Educ Psychol 41:75–86, 2006). We illustrate how integrating evidence from multiple theoretical perspectives leads to the development of more powerful approaches to learning and instruction through a review of the premises, evolution, and research behind Self-Regulated Strategy Development (SRSD) in the area of writing.  相似文献   

Suitable work for women? Roles,relationships and changing identities of ‘other adults’ in the early years classroom     

Jo Barkham 《British Educational Research Journal》2008,34(6):839-853

This article explores some of the issues around the agenda for workforce reform as it applies to professionals who work in early years classrooms (4–7 year olds), who work alongside class teachers in supporting learning. Their changing roles, responsibilities and professional identities are examined through a small scale case study of four women, two nursery nurses and two teaching assistants, from an infants school in a suburb of Bristol. Their close professional and personal relationships with the six female class teachers with whom thery work are considered. Their stories are analysed for their significance as women whose levels of skill and dedication are undervalued in terms of career structure, salary and job security. Whilst contributing to the debates around the changing roles and the valuable work of teaching assistants, this research endorses the view that these professionals' voices are too often silenced in educational debates and in strategic decision making.  相似文献
