This paper focuses on the problem of identifying influential users of micro-blogging services. Twitter, one of the most notable micro-blogging services, employs a social-networking model called "following", in which each user can choose who she wants to "follow" to receive tweets from without requiring the latter to give permission first. In a dataset prepared for this study, it is observed that (1) 72.4% of the users in Twitter follow more than 80% of their followers, and (2) 80.5% of the users have 80% of users they are following follow them back. Our study reveals that the presence of "reciprocity" can …
Grading Practice Influence On The Value Of An Assigned Grade, Carrie Bala
Grading Practice Influence On The Value Of An Assigned Grade, Carrie Bala
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
This article presents results of a study of grading practice influence on the value of an assigned grade. The value of an assigned grade, as an indication of student achievement of learning goals, was measured using the Utah Criterion-Referenced Test (CRT) in the subjects of Geometry and Algebra 2. The grading policies of six mathematics teachers at the same high school were categorized according to grading practice and their combined 587 students' scores on the Utah CRT were collected and analyzed. The findings suggest that certain grading practices , such as the use of a 1-4 scale and a criterion-referenced …

The structural and magnetic properties of Ho2Fe17−xMnx (x=0-5) have been investigated by x-ray diffraction, Mössbauer spectroscopy and DC magnetization measurements (0-5 T) over the temperature range 4.5-350 K. Similar to other ferrimagnetic R2Fe17-xMnx systems, the unit cell volume generally increases with Mn content other than for low Mn values where a slight maximum is detected around x ∼ 0.5. The nature of the magnetic phase transitions around TC is shown by Arrot plot analysis to be second order for all samples. The Curie temperature remains essentially unchanged …

Anuran sex ratio at breeding sites is typically male biased. Such sex ratios may be due to poor female survival, to females not breeding as frequently as males and/or to males becoming sexually mature earlier than females. In the present study, the first two factors are analyzed in a common toad (Bufo bufo) population in southern Sweden. Toads were captured, marked and recaptured at the breeding site during 5 years. Within season capture patterns were analyzed using the Jolly-Seber model and among-year captures using the Closed robust design model. Population estimates of males and females yielded an among year variation …

Tight junction proteins are important for intestinal homeostasis. They prevent paracellular transport of large molecules and maintain cell polarity. Impaired tight junction function leads to a more permeable intestinal epithelial barrier and therefore potentially increases disease risk. Limited information is available concerning the effects of food components on the intestinal barrier, particularly paracellular permeability and tight junction proteins. In vitro studies with intestinal epithelial cells and in vivo studies using animal models have demonstrated that dietary n-3 and n-6 polyunsaturated fatty acids (PUFAs), particularly n-3, can reduce intestinal inflammation and permeability. PUFAs can induce transcriptional regulators which may act in …
