Holistic information behavior and the perceived success of work in organizations     

Isto Huvila  Farhan Ahmad 《Library & information science research》2018,40(1):18-29

Surprisingly little is known about the relationship between perceived work success and information behavior. This study shows that holistic (versus organization-centric) information behavioral preferences are related to interaction and exchange oriented perceptions of the success of work. The findings were drawn from a partial least square structural equation modeling (PLS-SEM) based analysis of the survey data (N?=?305) collected from employees of a large multinational corporation. The findings suggest that holistic information behavior is more strongly related to social measures of success, whereas their association with quantitative measures tends to be lower. From the perspective of information behavior research, the findings suggest that holism seems to be a similar factor to, for instance, task complexity or personality, which influences human information behavior and, for instance, perceptions of relevance. From a practical perspective, the study suggests that the promotion of specific facets of measuring success and patterns of information behavior can be used to influence the orientation of working between centrifugality and openness.  相似文献

Ladder realizations of multivariable positive real functions     

M.O. Ahmad  C.H. Reddy  V. Ramachandran  M.N.S. Swamy 《Journal of The Franklin Institute》1979,307(2):71-81

Necessary and sufficient conditions are obtained for the realization of an m-variable positive real function (PRF) as the impedence function of a resistively-terminated ladder network of m lossless two-ports connected in cascade. Each two-port is a single-variable lossless ladder with all of its transmission zeros either at the origin or at finity. Conditions are also obtained when each of the two-ports is a Fujisawa-type lowpass ladder.  相似文献   

解决短期高峰需求的成本效益策略     

Ahmad Hashem  Mansor Fadzil 《开放教育研究》2007,13(1)

For most open universities, in fact for most universities, there will arise occasions when some online activities will have to be completed by all students in a very short time interval. These occasions usually result in a great rush to get online as quickly as possible; the rush is often made worst by the limited good choices on offer such that usually only the earliest can get the best. Choosing and confirming elective subjects, when only a limited number for each are offered, on a first-come-first-served basis is an example.At the Open University Malaysia the rush occurs when confirming offered subjects and choosing face-to-face meeting timetable. Most students rushed to be earliest to ensure choice slots in the timetable are obtained.Available I. T. resources such as Internet bandwidth and servers cannot cope with these short-term sustained peak demands. Unless these peak demands are met, however, online services will slow down drastically resulting in long queues of users waiting to be served. Providing excess capacity, if at all possible, to ensure these short duration peak demands can be met would not be cost-effective since most of the time these resources are not utilised. This paper will look at some cost-effective approaches to meeting these short-term peak demands.  相似文献   

Antioxidants in aqueous extract of Myristica fragrans (Houtt.) suppress mitosis and cyclophosphamide-induced chromosomal aberrations in Allium cepa L. cells     

Akinboro A  Mohamed KB  Asmawi MZ  Sulaiman SF  Sofiman OA 《Journal of Zhejiang University. Science. B》2011,12(11):915-922

In this study, freeze-dried water extract from the leaves of Myristica fragrans (Houtt.) was tested for mutagenic and antimutagenic potentials using the Allium cepa assay. Freeze-dried water extract alone and its combination with cyclophosphamide (CP) (50 mg/kg) were separately dissolved in tap water at 500, 1000, 2000, and 4000 mg/kg. Onions (A. cepa) were suspended in the solutions and controls for 48 h in the dark. Root tips were prepared for microscopic evaluation. 2,2-Diphenyl-1-picrylhydrazyl (DPPH) free radicals’ scavenging power of the extract was tested using butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) as standards. Water extract of Myristica fragrans scavenged free radicals better than BHA, but worse than BHT. The extract alone, as well as in combination with CP suppressed cell division, and induced chromosomal aberrations that were insignificantly different from the negative control (P≤0.05). However, cytotoxic and mutagenic actions of CP were considerably suppressed. The observed effects on cell division and chromosomes of A. cepa may be principally connected to the antioxidant properties of the extract. The obtained results suggest mitodepressive and antimutagenic potentials of water extract of the leaves of M. fragrans as desirable properties of a promising anticancer agent.  相似文献   

You can lead a horse to water but you cannot make him learn: Smartphone use in higher education          下载免费PDF全文

Smartphone technology is penetrating world markets and becoming ubiquitous in most college settings. This study takes a naturalistic approach to explore the use of these devices to support student learning. Students that had never used a smartphone were recruited to participate and reported on their expectations of the value of smartphones to achieve their educational goals. Instrumented iPhones that logged device usage were then distributed to these students to use freely over the course of 1 year. After the study, students again reported on the actual value of their smartphones to support their educational goals. We found that students' reports changed substantially before and after the study; specifically, the utility of the smartphone to help with education was perceived as favorable prior to use, and then, by the end of the study, they viewed their phones as detrimental to their educational goals. Although students used their mobile device for informal learning and access to school resources according to the logged data, they perceived their iPhones as a distraction and a competitor to requisite learning for classroom performance.  相似文献
