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

Guggulsterone, a mixture of cis (E) and trans (Z) isomers (7∶3 w/w) was synthesized from 16-DPA. The isomers were separated
by column chromatography and evaluated for cardioprotective and antioxidant activities. Myocardial necrosis induced by isoproterenol
in rats caused marked increase in serum creatine phosphokinase and glutamate pyruvate transaminase. Simultaneously in ischemic
heart, phospholipase, xanthine oxidase and lipid peroxides were enhanced following depletion of glycogen, phospholipids and
cholesterol. Treatment with guggulsterone and its both isomers at the dose of 50 mg/kg po., significantly protected cardiac
damage as assessed by the reversal of blood and heart biochemical parameters in ischemic rats. The cardioprotective activity
of guggulsterone and of both the isomers were compared with that of gemfibrozil at the same doses. Guggulsterone and both
the isomers at tested concentrations (5–20mM) inhibited oxidative degradation of lipids in human low-density lipoprotein and
rat liver microsomes induced by metal ionsin vitro. The drug counteracted against the generation of superoxide anions (O2) and hydroxyl radicals (OH−) in non-enzymic test systems. It is suggested that cardioprotective and antioxidant activities of synthetic guggulsterone
and guggulsterone obtained from gum resinCommiphora mukul that contains isomers E & Z in the ratio of 46∶54w/w are the same. 相似文献

Introductory engineering courses are either programme specific or expose students to engineering as a broad discipline by including materials from various engineering programmes. A common introductory engineering course that spans different engineering programmes raises challenges, including the high cost of resources as well as the lack of background courses of first-year students. This paper presents the design, implementation and evaluation of a first-year common engineering course that uses low-cost materials to expose students to a structured engineering design process. The course is explicitly designed to satisfy the Accreditation Board for Engineering and Technology criteria for engineering programmes. Our experience with the course shows that not only students are able to follow a structured design process successfully but we also believe that most of the ABET criteria are being delivered through the course. 相似文献

Financial challenges have forced many publicly funded academic institutions in Ontario to adopt a corporate model and to use market tools to compete in the higher education market and maintain their enrolment and revenue levels. This study has analyzed how competition affects publicly funded universities in Ontario. Competition was examined by relating universities’ expenditures on price and non-price competitive variables (awards, marketing, graduates, and professors), as well as population to the total number of applicants, total number of enrollees, and capacity filling ratio over the period of 2006–2013. The study used quantitative research design and panel data regression method to draw conclusions. This study provides empirical evidence on how the effect of the adopted competitive variables varies for each university. 相似文献

Research comparing special education for Jews and for Palestinian Arabs in Israel outlines major inequalities. This situation has remained largely unchanged for decades and there is little evidential reason to believe there will be improvement in the near future. Palestinian children requiring special education are adversely affected by a combination of institutionalised discrimination and neglect and the implications of living in a traditional society that is reluctant to adopt outlooks necessary for modernising education, particularly for children with special needs. To the best of our knowledge, no overview of special education for the Palestinian minority in Israel has been published in English to date. While change is most likely to occur as a result of effective activism within the Palestinian Arab community, high rates of poverty and political marginalisation remain a daunting obstacle. 相似文献

This article examines petitions submitted to the Egyptian state by students and parents over the span of a century. These sources reveal that Egyptians from across the economic spectrum were shifting their construction of schooling in response to changing political and educational policies and evolving conceptions of educational need. Over the course of the nineteenth and early twentieth centuries, parents and students were increasingly appealing to discourses concerning education, girls’ schooling and nationalism as a way to frame their personal pursuits as an extension of national advancement. As a result, petitioners saw education not as a matter of charity or luxury, but rather as a fundamental way to prevent ‘losing’ a brighter future. Ultimately, this shift in the concept of educational need underwrote the development of mass educational systems of the twentieth century as a cornerstone of the relationship between even the poorest of citizens and the Egyptian state. 相似文献

Drawing from recent debates about Muslim immigrants’ lack of integration into European societies, the current article advances a main argument regarding the nexus between soccer and Muslim immigrants’ integration within their host European societies by reviewing dominant theoretical models and focusing on elite European male Muslim soccer players. Considering the growing recent debate about the role of Muslim immigrants in their European societies, soccer has the potential to assist European countries to increase Muslims’ integration level. Elite Muslim soccer players are among the most influential immigrants in European societies. Muslim soccer players could contribute to increase understanding and community unity between different social groups within European societies as many of them prove that identity hyphenation and combining ethnicity and European nationality is possible for Muslim immigrants. Soccer could give more confidence to the generation of young Muslims about being accepted by European majorities. 相似文献

In this paper, a novel approach for the design of an indirect adaptive fuzzy output tracking excitation control of power system generators is proposed. The method is developed based on the concept of differentially flat systems through which the nonlinear system can be written in canonical form. The flatness-based adaptive fuzzy control methodology is used to design the excitation control signal of a single machine power system in order to track a reference trajectory for the generator angle. The considered power system can be written in the canonical form and the resulting excitation control signal is shown to be nonlinear. In case of unknown power system parameters due to abnormalities, the nonlinear functions appearing in the control signal are approximated using adaptive fuzzy systems. Simulation results show that the proposed controller can enhance the transient stability of the power system under a three-phase to ground fault occurring near the generator terminals. 相似文献
