Case study: library usage at an Indian medical college     

Shah C 《Health information and libraries journal》2011,28(1):77-81

This issue's feature column reports on the findings of a small survey of library users carried out in an Indian medical college with a traditional curriculum. The study found that the main reason a student visited the library was to consult text books. Although the majority of students were satisfied with the library facilities, the study suggests that more needs to be done to promote self-directed learning. JM.  相似文献   

Controlled electroporation of the plasma membrane in microfluidic devices for single cell analysis   总被引：1，自引：0，他引：1  

Shah D  Steffen M  Lilge L 《Biomicrofluidics》2012,6(1):14111-1411110

Chemical cytometry on a single cell level is of interest to various biological fields ranging from cancer to stem cell research. The impact chemical cytometry can exert in these fields depends on the dimensionality of the retrievable analytes content. To this point, the number of different analytes identifiable and additionally their subcellular localization is of interest. To address this, we present an electroporation based approach for selective lysis of only the plasma membrane, which permits analysis of the dissolved cytoplasm, while reducing contributions from the nucleus and membrane bound fractions of the cell analytes. The use of 100 μs long pulse and a well defined DC electric field gradient of ∼4.5 kV·cm⁻¹ generated by 3D electrodes initiates release of a cytoplasm marker in ≪1 s, while retaining nuclear fluorescence markers.  相似文献   

Study of C-Reactive Protein and Myocardial Infarction in the Indian Population     

Kavita Shalia  Sudha Savant  Vijaya A. Haldankar  Tulip Nandu  Poonam Pawar  Siddhi Divekar  V. K. Shah  Purvi Bhatt 《Indian journal of clinical biochemistry : IJCB》2012,27(1):74-82

To analyse the association of high sensitivity C-reactive (hsCRP) protein levels and −717A/G single nucleotide polymorphism of CRP with acute myocardial infarction (AMI) in the Indian population. Study population included 100 MI cases wherein 32 patients had experienced previous MI (MI-Group-1), 68 MI cases were recruited at presentation (MI-Group-2) and equal number of age and gender matched healthy individuals. hsCRP levels were determined by ELISA and genotyping of −717A/G was carried out by polymerase chain reaction-based restriction digestion method. The −717A/G genotypes did not influence hsCRP level and their distribution did not differ between groups. However, in the present study hsCRP demonstrated significant correlation with BMI in controls of both the genders and with triglycerides in females of AMI at presentation who otherwise are with low risk profile. Identifying traditional risk factors associated with inflammation may help in controlling the acute event.  相似文献

韩晓琳  张庆普  单伟 《中国科技论坛》2012,(3):68-73

深入理解合作知识创造机理有助于构建有效的合作知识创造管理模式,促进企业间的合作知识创造进程。可是,由于合作企业在战略规划、利益机制、企业文化和管理模式等方面存在差异,合作知识创造的机理非常复杂。在阐明结构化理论和合作知识创造理论一致性的基础上,应用结构二重性原理,从合作博弈、表意结构、支配结构和合法化结构四个维度对企业间合作知识创造的结构化演变机理进行了剖析,并构建了基于结构化模态的合作知识创造管理模式,以有效提高企业间合作知识创造绩效。  相似文献   

The Australian higher education quality assurance framework     

Mahsood Shah  Lucy Jarzabkowski 《Perspectives: Policy and Practice in Higher Education》2013,17(3):96-106

The Australian government initiated a review of higher education in 2008. One of the outcomes of the review was the formation of a national regulator, the Tertiary Education Quality and Standards Agency (TEQSA), with responsibilities to: register all higher education providers, accredit the courses of the non self-accrediting providers, assure quality against externally set standards and reduce risk by monitoring institutional performance on various measures. One of the key changes in Australian higher education quality assurance is the shift from a ‘fitness-for-purpose’ approach to quality assurance to a compliance-driven approach using an externally developed set of standards monitored by the national regulator, which has legislated powers to place sanctions on universities and other providers for non-compliance. This article outlines the new framework introduced by the government and analyses its limitations in assuring and improving quality in core and support areas. It cautions universities against being dominated by TEQSA's compliance agenda. Rather, it encourages the development and maintenance of shared governance principles and strong internal quality improvement processes along with the establishment of an outcomes focus, which will stand the test of external compliance auditing while allowing the institution to pursue its own educational objectives. The article is based on the authors’ experience and reflection on external, improvement-led quality audits in Australia over the past decade compared with the present compliance-oriented audits now required for institutional registration and ongoing accreditation.  相似文献   

Towards the successful integration of e-learning systems in higher education in Iraq: A student perspective     

Nisreen Ameen  Robert Willis  Media Noori Abdullah  Mahmood Shah 《British journal of educational technology : journal of the Council for Educational Technology》2019,50(3):1434-1446

This study aims to analyse the factors that can explain the adoption and effective use of a new e-learning system in Iraq. To achieve this, it uses a selection of factors that are present in the technology acceptance model (TAM) and the unified theory of acceptance and use of technology (UTAUT) model, and it includes three additional factors. The study hypothesises new relationships between the selected factors. Questionnaires were distributed to 300 university students in Iraq. Partial least squares-structural equation modelling (PLS-SEM) was used to analyse the data received. The findings suggest that perceived usefulness (PU), perceived ease of use (PEOU), subjective norms (SNs), information quality (IQ), system quality (SQ), technical support (TS) and self-efficacy (SE) have significant effects on behavioural intention (BI). In turn, BI and TS have significant direct effects on the actual use (AU) of e-learning systems. The factors age, gender and experience significantly moderated some of the relationships in the model. The research has several implications for policy makers, universities and the management of e-learning systems.  相似文献   

Expression and Reception: An Analytic Method for Assessing Message Production and Consumption in CMC     

Kang Namkoong  Dhavan V. Shah  Bryan McLaughlin  Ming-Yuan Chih  Tae Joon Moon  Shawnika Hull 《Communication methods and measures》2017,11(3):153-172

This article presents an innovative methodology to study computer-mediated communication (CMC), which allows analysis of the multi-layered effects of online expression and reception. The methodology is demonstrated by combining the following three data sets collected from a widely tested eHealth system, the Comprehensive Health Enhancement Support System (CHESS): (1) a flexible and precise computer-aided content analysis; (2) a record of individual message posting and reading; and (3) longitudinal survey data. Further, this article discusses how the resulting data can be applied to online social network analysis and demonstrates how to construct two distinct types of online social networks—open and targeted communication networks—for different types of content embedded in social networks.  相似文献

Physicochemical characteristics of various milk samples available in Pakistan     

Imran M  Khan H  Hassan SS  Khan R 《Journal of Zhejiang University. Science. B》2008,9(7):546-551

We report physicochemical characteristics of various kinds of liquid milk commercially available in Pakistan in comparison with those of fresh natural milk from animals. Milk samples were collected from local markets at Peshawar, Pakistan,and analyzed for their physical features, including moisture, total solids, specific gravity, conductivity, viscosity and titratable acidity (lactic acid equivalent), and chemical components and macro-minerals, including total protein, casein, lactose, ash and minerals (Na, K and Mg). These items were compared with the physicochemical characteristics of the fresh natural milk samples from buffalo, cow and goat. The results were also compared with reported nutritional quality of milk from various countries and World Health Organization (WHO) standards. We found that all the physical features and chemical components of commercially available milk in Pakistan markets meet WHO's requirements, except for Na, K, Ca and Mg, which are below the standards.  相似文献   

Silent Partners: Developing a Critical Understanding of Community Partners in Technical Communication Service-Learning Pedagogies     

Amy C. Kimme Hea  Rachael Wendler Shah 《Technical Communication Quarterly》2016,25(1):48-66

Although many technical communication teachers and programs integrate some form of service-learning pedagogy, there is a dearth of technical communication research on the silent partners of these projects: the community partners. Drawing upon research data from 14 former community partners of professional writing service-learning courses, the authors suggest that understanding community partners’ own self-defined stakes in service-learning projects can challenge hyperpragmatist representations of community partners and aid us in the continued creation, management, and critical evaluation of service-learning pedagogies and curricula.  相似文献
