Proctored versus unproctored online testing using a personality measure: Are there any differences?

Proctored versus unproctored online testing using a personality measure: Are there any differences?

Date: August 2007
Creator: Gupta, Dipti
Description: Impetus in recruiting and testing candidates via the Internet results from the popularity of the World Wide Web. There has been a transition from paper-pencil to online testing because of large number of benefits afforded by online testing. Though the benefits of online testing are many, there may be serious implications of testing job applicants in unproctored settings. The focus of this field study was two-fold: (1) to examine differences between the proctored and unproctored online test administrations of the ipsative version of Occupational Personality Questionnaire (OPQ32i and (2) to extend online testing research using OPQ32i with a U.S population. A large sample (N = 5223) of archival selection data from a financial company was used, one group was tested in proctored and the other in unproctored settings. Although some statistical differences were found, very small to small effect sizes indicate negligible differences between the proctored and unproctored groups. Principal component analysis with varimax rotation was conducted. The scales not only loaded differently from the Great Eight factor model suggested by SHL, but also differently for the two groups, limiting their interpretability. In addition to the limitations and future directions of the study, the practical implications of the results for ...

Production and characterization of a novel extracellular polysaccharide produced by Paenibacillus velaei, sp. nov

Production and characterization of a novel extracellular polysaccharide produced by Paenibacillus velaei, sp. nov

Access: Use of this item is restricted to the UNT Community.
Date: August 2000
Creator: Sukplang, Patamaporn
Description: Paenibacillus velaei, sp. nov. is a soil bacterium capable of producing an unusually large amount of exopolysaccharide (EPS). The EPS contains glucose, mannose, galactose and fucose in a molar ratio of 4:2:1:1. The molecular weight of the EPS is higher than 2x106. The viscosity of 1% EPS is 1300 cP when measured at a shear rate of 1 sec-1. Physiological parameters for optimal production of the EPS were studied and it was found that 1.4 g dry weight per 1 l of medium was produced when the bacteria were grown at 30EC and the pH adjusted at 7± 0.2 in a medium containing glucose as the carbon source. Growing the bacteria on different carbon sources did not alter the quantity or the composition of the EPS produced. No toxicity effects were observed in mice or rats when EPS was administered in amounts ranging from 20 to 200 mg per kg body weight. The data obtained from physical, chemical and biological properties suggest that the EPS may be employed in several industrial and environmental applications. It is an excellent emulsifier, it holds 100 times its own weight in water, it is not toxic, and it can be used to remove mercury, ...

A Production Book for an Experimental Staging of Nikolai Gogol's The Inspector General

A Production Book for an Experimental Staging of Nikolai Gogol's The Inspector General

Date: August 1966
Creator: Peninger, John Edward
Description: The January 17 and 18, 1966, thesis production presented at North Texas State University was an experimental production of The Inspector General, as based on historical, philosophical, and analytical study of both the play and the author, Nikolai Gogol. A thesis production consists of a written analysis and evaluation of the play and its author and the actual production of the play. The thesis production enables the candidate to illustrate his mastery of theatre discipline. The written portion demonstrates his ability to develop the concepts necessary to the production of a play, and the presentation of the play offers the candidate the opportunity to show his creativity and aesthetic understanding of theatre.

The Production Effects of Protectionist Announcements: An Examination of the Steel Industry

The Production Effects of Protectionist Announcements: An Examination of the Steel Industry

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Pharr, Matthew C.
Description: The well-being of the American steel industry is vital to the overall health of the United States (U.S.) economy. This belief is, in part, the impetus for the enactment of protective tariffs and quotas. This paper examines the impact of the announcement of the 2001 tariffs. Numerous forces have buffeted the U.S. steel industry over the last decade. Domestic steel firms operate in a highly global, fiercely competitive, and capital-intensive industry. This environment has proven inhospitable to the U.S. steel industry, widely criticized for inefficiency and overcapacity. A regression analysis finds that the announcement of the 2001 tariffs had no statistically significant impact on U.S. domestic raw steel production. Supporting theories are reexamined, and the implications of this finding for trade policy are explored.
