background and purpose: there are 3 specific reasons for education evaluation: to justify the existence and budget of the training department by showing how it contributes to the organization’s objectives and goals, to decide whether to continue or discontinue training programs, and to gain information on how to improve future training programs. we aimed to assess the effectiveness a media produ...

the virulence of four iranian isolates and one exotic isolate of beauveria bassiana on the fifth instar nymphs and also five iranian isolates and one exotic isolate of it on the adults of eurygaster integriceps puton was studied using dipping and topical micro-application techniques, respectively. nymphs were highly susceptible to the isolates. comparison of lc50 values showed no significant di...

the potential of bulk starter fermentation strategy for production of a cost-effective and safe source of β-galactosidase was investigated. three different bulk starter media with different compositions were selected, and an industrial yogurt starter culture strain, l. bulgaricus dsm 20081 was cultivated in these media under ph-controlled conditions (ph=5.6) at 43°c. the media consisted of 1) b...

Different compositions of liquid media were used for their efficacy in the production of beta-galactosidase by Aspergillus oryzae in submerged fermentation. Enzyme production was improved by switching from lactose-based media to soybean meal- and wheat bran-based media. Further improvement was made when the soybean meal medium was supplemented with sodium nitrate and magnesium sulfate. Res...

In this paper we explore the production of streaming media that involves live and recorded content. To examine this, we report on how the production practices and process are conducted through an empirical study of the production of live television, involving the use of live and non-live media under highly time critical conditions. In explaining how this process is managed both as an individual...

Thirteen species of Streptomycetes, Arthrobacters and Mycobacterium were studied for the determination of a potential cholesterol oxidase producer. Only Streptomyces fradiae and Streptomyces rishiriences were found to be capable of producing this enzyme. Streptomyces fradiae was selected for the production of cholesterol oxidase and cultured in different media to find optimum media and con...

exposes. The news, as Hamilton (2004) remarks, is an “information good,” a thing to be sold to advertisers and audiences. Although major corporate scandals get news coverage when they break, news organizations do not invest heavily in investigating private-sector actions (→ Investigative Reporting). News organizations and journalists do not so much promote corporate power as they ignore it, all...

Instructional content designers of online learning platforms are concerned about optimal video design guidelines that ensure course effectiveness, while keeping video production time and costs at reasonable levels. In order to address the concern, we use clickstream data from one Coursera course to analyze the engagement, motivational and navigational patterns of learners upon being presented w...

Nowadays, multiple video cameras are employed for live broadcast and recording of almost all major social events, and all these camera streams are aggregated and rendered into one video program for audiences. While this content composition process aims at presenting the most interesting perspective of an event, it leads to the problem of how to fully customize the final video program to differe...
