The Effect of Information Literacy Instruction on Library Anxiety Among International Students

Description: This study explored what effect information literacy instruction (ILI) may have on both a generalized anxiety state and library anxiety specifically. The population studied was international students using resources in a community college. Library anxiety among international students begins with certain barriers that cause anxiety (i.e., language/communication barriers, adjusting to a new education/library system and general cultural adjustments). Library Anxiety is common among college student… more

The Effect of Information Technology on Productivity in the Retail Sector

Description: Three major research questions were addressed in this study. First, does information technology contribute to the productivity of retail institutions? Second, to what degree can information technology be substituted for labor and capital in retailing? Finally, is the market efficient in allocating information technology? These questions were chosen after a careful review of the literature revealed gaps in these areas.

Effect of Inorganic Phosphate on the Morphology and Poly-β-Hydroxybutyrate Content of Azotobacter Vinelandii Atcc 12837

Description: This study was designed to determine the effect of inorganic phosphate in the growth media of A. vinelandii on the synthesis and accumulation of poly-β-hydroxybutyrate (PHB) and cellular morphology. Burk's media with no added phosphate and ten times normal phosphate resulted in altered cells, lower levels of protein, and decreased cell populations. PHB accumulation was much higher in the cultures with no added phosphate; however, the polymer granules differed in appearance from those of normal … more

The Effect of Intensive Remotivation Techniques on Institutionalized Geriatric Mental Patients in a State Mental Hospital

Description: The problem with which this study is concerned is that of ascertaining the effects of intensive Remotivation Techniques on institutionalized geriatric mental patients in terms of their ward behavior, self-concept, and visual-motor perceptions and to compare these with the effects of a similar group experience that does not emphasize patient-staff or patient-patient interactions, and a third group which acts a a control. The investigation is designed to answer or obtain information concerning th… more

The Effect of Interactive Multimedia on the Critical Writings of Art History Survey Students

Description: In response to ideological issues that have emerged the last two decades from feminism, multiculturalism and postmodernism, the introductory art history survey is undergoing major revisions not only in structure and content, but also in instructional methodology. Art history professionals and art educators alike are questioning whether pedagogical methods traditionally employed in the survey are adequate for meeting the goals of visual literacy and development of critical and analytical skills.… more

The Effect of Intermediate Filament Inhibitors on Steroidogenesis and Cytoskeleton in Y-1 Mouse Adrenal Tumor Cells

Description: When Y-1 mouse adrenal tumor cells were treated with sodium orthovanadate, an intermediate filament (IF) inhibitor in BHK21-F cells, there was no change in the amount of 20α-dihydroprogesterone produced. A neurofilament inhibitor, β, β'-iminodipropionitrile (IDPN), enhanced the ability of Y-1 cells to produce steroid in response to ACTH by acting on the plasma membrane. Electron microscopy of Y-1 cells extracted with Triton X-100 revealed that both vanadate and IDPN caused the aggregation of cy… more

The Effect of Intervalence-Band Absorption, Auger Recombination, Surface Recombination, Diffusion and Carrier Cooling on the Picosecond Dynamics of Laser-Induced Plasmas in Germanium

Description: The picosecond optical response of germanium is investigated by performing excitation-probe experiments on a thin, intrinsic-germanium wafer maintained at 135 K. The results of three distinct experiments are reported: (1) the transmission of a single pulse is measured as a function of irradiance, (2) the probe transmission is measured at a fixed time after excitation as a function of the excitation energy, and (3) the transmission of a probe pulse is monitored as a function of time after excita… more

The Effect of It Process Support, Process Visualization and Process Characteristics on Process Outcomes

Description: Business process re-engineering (part of the Business Process Management domain) is among the top three concerns of Information Technology (IT) leaders and is deemed to be one of many important IT leveraging opportunities. Two major challenges have been identified in relation to BPM and the use of IT. The first challenge is related to involving business process participants in process improvement initiatives using BPM systems. BPM technologies are considered to be primarily targeted for develop… more

The Effect of Item Distance on Organization in the Free Recall of Words

Description: The purpose of the present study was to investigate the effect of item distance, which is defined as the absolute number of words separating a single item from the other items of the category, upon clustering of the removed items. By studying clustering, psychologists hope to gain knowledge of the effect of organization on memory.

The Effect of Learning-Set Acquisition on the IQs of Disadvantaged Preschool Children

Description: General learning ability is a combination of many relatively independent abilities, some of which have not yet been identified and studied experimentally. The acquisition of learning sets, a learning ability which has received considerable attention in the literature, involves the ability to solve single problems, generalize their solutions, transfer such information from one problem to another, and form concepts. Learning set is the acquired ability to solve a particular kind of problem. Discr… more

Effect of Light and Other Environmental Factors on Growth and Carotenogenesis of Corynebacterium Species Strain 7E1C

Description: This investigation studies effects of environmental factors on growth and carotenogenesis in Corynebacterium strain 7ElC. Changes in pH were found to effect growth more than carotenogenesis. However, certain nutrients or long incubation periods stimulated carotenoid formation more than growth. Dark conditions in a mineral salts-glucose medium stimulated growth, but minimized carotenogenesis. Tryptic soy broth or yeast extract elicited carotenogenesis in darkness. Although brief light exposure d… more

The Effect of Light on Carotenoid Synthesis in Corynebacterium 7E1C

Description: The effects of light, light "mimicking" chemicals, and protein synthesis inhibitors on the photo-induced carotenogenesis of Corynebacterium 7EIC were studied. Changes in the dosage of fluorescent light applied to dark grown cells showed a dose related carotenogenic response. Maintaining the same dosage but varying the wavelength of monochromatic light revealed that light with a wavelength of 280 to 450nm was responsible for photo-induction. It further showed a peak of photo-induction between th… more

Effect of Loneliness on Older Adults' Death Anxiety

Description: Previous research, as well as theory, has supported the existence of a relationship between death anxiety and loneliness in older adults but a causal examination has not been possible until now. A hypothesized model was developed which states that loneliness will lead to death anxiety mediated by cultural worldview. Longitudinal data was analyzed using Structural Equation Modeling in order to more fully explore this potentially causal relationship. The primary model was supported suggesting tha… more

The Effect of Long-Term Moderate Amounts of Ethanol on Paraventricular Nuclei Activity on Cold Stressed Adult Rats

Description: The effects of moderate, long-term intake of ethanol on the hypothalamic response to cold stress were examined. The long-term experimental animals were given .25 ml of 28% ethanol or .25 ml of water orally once a day, five days a week for fourteen months. A stainless steel electrode was then surgically implanted into the paraventricular nucleus, after which the animal was subjected to cold stress (-150 C, 10 min.). Recordings were taken in the forms of frequency and activity. The data clearly i… more
