Abstract:

It is recognised that the overall success of a business depends very much on the quality of management planning, and management needs relevant information in order to plan effectively. However, most management information systems are centered on information obtained in-house. Very little emphasis is placed on external information, except some very general information published by Government bodies. If it is possible to incorporate information from other similar firms into the analysis, a firm will be able to plan and therefore compete more efficiently and improve its overall performance. The a

In this paper the authors describe a method to integrate explanatory business analytics in OLAP information systems. This method supports the discovery of exceptional values in OLAP data and the explanation of such values by giving their underlying causes. OLAP applications offer a support tool for business analysts and accountants in analyzing financial data because of the availability of different views and managerial reporting facilities. The purpose of the methods and algorithms presented here, is to extend OLAP applications with more powerful analysis and reporting functions. The authors

Abstract:

Conversation with a remote person can interfere with performing vision-based tasks. Two experiments tested the role of general executive resources and spatial attentional resources in this interference. Both experiments assessed performance in vision-based tasks as participants engaged in a language task involving a virtual remote speaker. In both experiments, the language task interfered with the vision task more when participants were speaking or planning what to say next than when they were listening. In Experiment 1, speaking or planning what to say next were also associated with higher in

Several studies have demonstrated that dynamic visual noise (DVN) does not interfere with memory for random matrices. This has led to suggestions that (a) visual working memory is distinct from imagery, and (b) visual working memory is not a gateway between sensory input and long-term storage. A comparison of the interference effects of DVN with memory for matrices and colored textures shows that DVN can interfere with visual working memory, probably at a level of visual detail not easily supported by long-term memory structures or the recoding of the visual pattern elements.

Research on perceptual learning shows that the way stimuli are presented leads to different outcomes. The intermixed/blocked (I/B) effect is one of these outcomes, and different mechanisms have been proposed to explain it. In human research, it seems that comparison between stimuli is important, and the placement of a distractor between the pre-exposed stimuli interferes with the effect. Results from animal research are usually interpreted in different terms because the type of procedure normally used in animal perceptual learning does not favour comparison.

An experimental study comparing Kessler’s and Tsuge’s techniques for tendon suture was undertaken in dogs. Both second and fifth flexor digitorum profundi tendons of the left forepaw were divided in the segment corresponding to zone 2 of human hands. Following division, the tendons to the second digit were repaired by Kessler’s technique and those to the fifth digit by Tsuge’s method. Results were evaluated by means of standard and polarized – light microscopy, intravascular dye injections and tensile strength tests. Both ordinary and polarized – light microscopy showed that a microscopical ga

Abstract:

Human gastrointestinal illness due to Giardia duodenalis infection continues to be a public health problem. The ability to detect Giardia cysts is important in assessing the public health risk associated with environmental contamination. The low concentration of cysts in natural waters makes the use of the polymerase chain reaction (PCR) desirable in DNA probe-based detection methods. To date, amplification of DNA in environmental samples has been difficult to achieve. Humic compounds and/or other PCR inhibitors co-extract with nucleic acids, interfering with the polymerase reaction and loweri

Abstract:

Standard toxicity tests might not be fully adequate for evaluating nanomaterials since their unique features are also responsible for unexpected interactions. The in vitro cytokinesis-block micronucleus (CBMN) test is recommended for genotoxicity testing, but cytochalasin-B (Cyt-B) may interfere with nanoparticles (NP), leading to inaccurate results. Our objective was to determine whether Cyt-B could interfere with MN induction by TiO2 NP in human SH-SY5Y cells, as assessed by CBMN test. Cells were treated for 6 or 24 h, according to three treatment options: co-treatment with Cyt-B, post-treat

INTRODUCTION: Fixed orthodontic appliances have been regarded as a common causative factor of oral lesions. To manage soft tissue discomfort, most orthodontists recommend using a small amount of utility wax over the brackets in order to alleviate trauma. This in vitro study aimed at evaluating friction generated by two types of bracket protectors (customized acetate protector [CAP] and temporary resin protector [TRP]) during the initial stages of orthodontic treatment. METHODS: An experimental model (test unit) was used to assess friction. In order to measure the friction produced in each test

ABSTRACT The viral immediate-early transactivator Rta/Orf50 is necessary and sufficient to initiate Kaposi's sarcoma-associated herpesvirus/human herpesvirus 8 (KSHV/HHV-8) reactivation from latently infected cells. Since Rta/Orf50 is conserved among all known gamma-2-herpesviruses, we investigated whether the murine gamma-68-herpesvirus (MHV-68) and rhesus monkey rhadinovirus (RRV) homologs can functionally substitute for KSHV Rta/Orf50.

Abstract:

Export performance has long been an issue of concern in the literature; however, there has been little research on managers’ evaluations of their firms’ performance in the presence of multiple export objectives. This study proposes a framework for understanding managerial assessments of export performance and illustrates its application using the analytic hierarchy process methodology. The framework explicitly acknowledges that the importance of different export objectives may differ both within and between firms and that the latter may also differ in terms of the frame of reference and/or tim

The infection has rapidly spread out all over the world and Italy has been the first European country experiencing the endemic wave with unexpected clinical severity in comparison with Asian countries. It has been shown that SARS-CoV-2 utilizes angiotensin converting enzyme 2 (ACE2) as host receptor and host proteas

Abstract:

In nineteenth-century Canada, a Census was conducted every ten years, beginning in 1851. Historians have tried to use the information in the local, provincial, and national Censuses to determine the rate of mortality and causes of death. The mortality statistics are thought to be reliable after 1921, but practical as well as conceptual problems interfere with attempts to establish retrospective mortality patterns using the nineteenth-century Census. In this paper, I will review the problems with this source on mortality. I will then compare the Census data with that derived from a study of a p

Abstract Astronomical imaging can be broadly classified into two types. The first type is amplitude interferometry, which includes conventional optical telescopes and very large baseline interferometry (VLBI). The second type is intensity interferometry, which relies on Hanbury Brown and Twiss-type measurements. At optical frequencies, where direct phase measurements are impossible, amplitude interferometry has an effective numerical aperture that is limited by the distance from which photons can coherently interfere. Intensity interferometry, on the other hand, correlates only photon fluxes a

Good correlation of [14C]IAP with microsphere flow estimates in the gray matter was found. In the white matter, however, [14C]IAP flow estimates were consistently lower than microsphere flow estimates. Error analysis of both techniques and comparison with previous studies suggest that peculiarities of white matter arterial vasculature with preferential microsphere accumulation may lead to this discrepancy.
