Computer literacy for nursing educators : attitudes, behaviors and education.

COMPUTER LITERACY FOR NURSING EDUCATORS: ATTITUDES, BEHAVIORS AND EDUCATION September, 1987 ANDREA JANE WALLEN B.S. California State University, San Francisco M.S. University of California, San Francisco Medical Center Ed. D. University of Massachusetts Directed by: Dr. Thomas Hutchinson The primary purpose of this study was to investigate nursing educator's attitudes towards computers. Attention was focused on identifying whether positive or negative attitudes predominated, and if a correlation exists between attitudes and behaviors. In addition, an experimental design examined the relationship between attitude change and an inservice program designed to increase nurse educators' knowledge and improve their attitudes towards computer use. Three null hypotheses were tested for statistical signif¬ icance to 1) identify the percentage of nursing educators holding positive or negative attitudes towards computers, 2) identify if a relationship exists between nursing educators' attitudes and computer use behaviors, and 3) determine if participation in an inservice education program designed to increase knowledge, and promote positive attitudes towards computers was effective.
Questions and Answers about Fun at Work

R ecently, much has been said about "tun at work" environments and their importance for employee morale and productivity. Yet, there is no serious empirical or theoretical work on the nature or consequences of having fun in organizations. In this article we discover, through the eyes of practicing human resource managers, what a fun work environment is, its component characteristics, and its advantages for employees, work teams, and organizations. We also discover the specific types of things these human resource managers' organizations use to promote a fun work environment. Data were gathered from a national e-mail survey of human resource managers. There were 572 usable replies. The human resource managers strongly favor promoting a fun work environment because they believe such environments offer great benefits both to the individual and the organization. To them, fun working environments are here to stay, not just another passing managerial fad.
Fast efficient algorithm for enhancement of low lighting video

We describe a novel and effective video enhancement algorithm for low lighting video. The algorithm works by first inverting an input low-lighting video and then applying an optimized image de-haze algorithm on the inverted video. To facilitate faster computation, temporal correlations between subsequent frames are utilized to expedite the calculation of key algorithm parameters. Simulation results show excellent enhancement results and 4x speed up as compared with the frame-wise enhancement algorithms.
The bootstrap, covariance matrices and PCA in moderate and high-dimensions

We consider the properties of the bootstrap as a tool for inference concerning the eigenvalues of a sample covariance matrix computed from an $n\times p$ data matrix $X$. We focus on the modern framework where $p/n$ is not close to 0 but remains bounded as $n$ and $p$ tend to infinity. Through a mix of numerical and theoretical considerations, we show that the bootstrap is not in general a reliable inferential tool in the setting we consider. However, in the case where the population covariance matrix is well-approximated by a finite rank matrix, the bootstrap performs as it does in finite dimension.
Casein kinase 1δ functions at the centrosome and Golgi to promote ciliogenesis

CK1δ acts at the centrosome and Golgi to support polarized transport for ciliogenesis. It controls distribution of ciliary effectors Rab11, Rab8, CEP290, PCM1, and IFT20 and also promotes MT nucleation at the Golgi and positioning and integrity of the Golgi. Interaction of CK1δ with AKAP450 mediates Golgi MT nucleation and ciliogenesis.
Synaptic Integration of Olfactory Information in Mouse Anterior Olfactory Nucleus

Individual odorants activate only a small fraction of mitral cells in the mouse main olfactory bulb (MOB). Odor mixtures are represented by a combination of activated mitral cells, forming reproducible activation maps in the olfactory bulb. However, how the activation of a cohort of narrowly tuned mitral cells by odor mixtures is read out synaptically by neurons in higher-level olfactory structures, such as the anterior olfactory nucleus (AON), is mostly unknown. In the current study, we used intracellular and extracellular recordings to examine and compare responses of AON neurons and MOB mitral cells to a panel of structurally diverse odorants presented either as mixtures or as individual components. We found that a majority of individual AON neurons could be synaptically activated by several mixtures of structurally dissimilar components and by several dissimilar components in an effective mixture. The suprathreshold response of an AON neuron to an effective mixture often exceeded the sum of its suprathreshold responses to all of the components in that mixture, indicating a nonlinear combinatorial interaction. In contrast to the broad responsiveness of AON neurons, the majority of mitral cells were activated by only one or two components in a single mixture. The broader responsiveness of AON neurons relative to mitral cells suggests that individual AON neurons synaptically integrate several functionally distinct mitral cell inputs.
The GLV6/RGF8/CLEL2 peptide regulates early pericycle divisions during lateral root initiation

Small peptides of the Arabidopsis GLV/RGF/CLEL family are involved in different developmental programmes, including meristem maintenance and gravitropic responses. In addition, our previous report suggested that they also participate in the formation of lateral roots. Specifically, GLV6 is transcribed during the first stages of primordium development and GLV6 overexpression results in a strong reduction of emerged lateral roots. To investigate the cause of this phenotype we analysed primordium development in gain-of-function (gof) mutants and found that GLV6 induces supernumerary pericycle divisions, hindering the formation of a dome-shaped primordium, a prerequisite for successful emergence. The GLV6 phenotype could be reproduced by ectopic expression of the gene only in xylem-pole pericycle cells. Furthermore, GLV6 seems to function at the very beginning of lateral root initiation because GLV6 excess—either gene overexpression or peptide treatment—disrupts the first asymmetric cell divisions required for proper primordium formation. Our results suggest that GLV6 acts during lateral root initiation controlling the patterning of the first pericycle divisions.
Infrastuctural Background Of The Everyday Physical Education In Hungarian High Schools

The Hungarian government is dedicated to supporting a healthy and sporty life-style, thus in the past years the number of initiatives directed to publicizing and promoting sports has increased considerably. The new Law of Public Education has put the emphasis on physical education and on organizing other sport events in schools. This led to the introduction, in a phasing-out manner, of the every-day physical education (PE). We were interested to know the infrastructural background of PE including the number and size of sports halls available for the students, how many classes can they accommodate at the same time, and when were they constructed. To this end a survey was conducted through telephone, contacting 200 high schools in 19 counties of Hungary. Do the schools have their own swimming pools, or do they conduct after-hours sports events. Data were analyzed using the EvaSys program. The time of construction of the schools and their sports halls spans a wide range between the years 1530 and 2005. So do the number of students, between 150-1200. Nineteen of the schools have none, 67% has one, and 18.8% two sports halls. The size of these halls is also very variable, while in some schools it is only 25 m2, in others it can be as large as 2295m2. In most cases the halls can accommodate one or two classes in parallel. Afternoon classes are held in 87% of the schools, and include basketball, fencing, and soccer, among others. However, only eleven of the interviewed high schools have swimming pools. Research has called the attention to the fact that the exercise of Hungarian youth is too little. This puts the emphasis on the promotion of physical activity in schools. While there are large differences in the infrastructural background in the schools involved in the survey, they all strive to conduct after-hours sport events.
Ergothioneine Contents in Fruiting Bodies and Their Enhancement in Mycelial Cultures by the Addition of Methionine

Abstract The levels of ergothioneine (ERG), which have been shown to act as an excellent antioxidant, were determined in both fruiting bodies and mycelia of various mushroom species. We found that ERG accumulated at different levels in fruiting bodies of mushrooms and showed up to a 92.3-fold difference between mushrooms. We also found that ERG accumulated at higher levels in mycelia than in fruiting bodies of economically important mushroom species such as Ganoderma neo-japonicum, G applanatum and Paecilomyces tenuipes. The addition of 2 mM methionine (Met) to mycelial culture medium increased the ERG contents in most mushroom species tested, indicating that Met is a good additive to enhance the ERG levels in a variety of mushroom species. Taking these results into consideration, we suggest that the addition of Met to the mycelial culture medium is an efficient way to enhance the antioxidant properties in economically important mushroom species.
Cultural meanings of brands and consumption: A window into the cultural psychology of globalization

With globalization, the number of individuals with knowledge about multiple cultures is on the rise. This article illustrates how studying consumer reactions to brands that are loaded with cultural meanings can contribute to developing a cultural psychology of globalization. Our review demonstrates that brands can be considered cultural ‘products’ – they are tangible, public representations of meanings and ideas shared in a culture. As such, incidental exposure to culturally symbolic brands can spontaneously evoke its attendant cultural meanings and trigger culturally appropriate behavioral decisions. Because globalization makes these brands readily available in diverse cultural contexts, consumer reactions to culturally symbolic brands often reflect people’s views about the cultural effects of globalization. Consumers would respond favorably to these brands when the associated cultural meanings reinforce the consumers’ cultural identity. In contrast, consumers would react negatively toward these brands when they are perceived to be a threat to the local culture. We identify the factors that promote one type of reaction over the other, and discuss how this line of research can further contribute to building a cultural psychology of globalization.

Improvement in Memory and Brain Long-term Potentiation Deficits Due to Permanent Hypoperfusion/Ischemia by Grape Seed Extract in Rats

Objective(s): Cerebral hypoperfusion/ischemia (CHI) is a neurological disease where impaired hippocampus electrical activity and cognition caused by a serial pathophysiological events. This study aimed to evaluate the effects of chronic oral administration of grape seed extract (GSE) on passive avoidance memory and long-term potentiation (LTP) after permanent bilateral common carotid arteries occlusion (2CCAO) in male adult rats. Materials and Methods: Thirty-two adult male Wistar rats were randomly divided into: 1) Sham+Veh, 2) Isch+Veh, 3) Sham+GSE, 4) Isch+GSE. In order to make 2CCAO as an animal model of CHI, carotid arteries were ligatured and then cut bilaterally. To evaluation of passive avoidance memory, step-down latency (STL) was measured and LTP was recorded from hippocampal dentate gyrus (DG) after high frequency stimulation (HFS) in all rats. Results: We found that memory was significantly impaired in rats after CHI (P<0.001) concomitant with hippocampal LTP inhibition (P<0.05, P<0.01 for LTP1 and LTP48 respectively). GSE treatment significantly improved memory impairment and increased hippocampal LTP in rats with 2CCAO. Conclusion: Our results in present study suggest that GSE exhibits therapeutic potential for short-and long-term memories as well as LTP in DG, which is most likely related at least in part to its antioxidative and free radical scavenging actions.
The Ethanol Metabolite Acetaldehyde Increases Paracellular Drug Permeability In Vitro and Oral Bioavailability In Vivo

Alcohol consumption leads to the production of the highly reactive ethanol metabolite, acetaldehyde, which may affect intestinal tight junctions and increase paracellular permeability. We examined the effects of elevated acetaldehyde within the gastrointestinal tract on the permeability and bioavailability of hydrophilic markers and drug molecules of variable molecular weight and geometry. In vitro permeability was measured unidirectionally in Caco-2 and MDCKII cell models in the presence of acetaldehyde, ethanol, or disulfiram, an aldehyde dehydrogenase inhibitor, which causes acetaldehyde formation when coadministered with ethanol in vivo. Acetaldehyde significantly lowered transepithelial resistance in cell monolayers and increased permeability of the low-molecular-weight markers, mannitol and sucrose; however, permeability of high-molecular-weight markers, polyethylene glycol and inulin, was not affected. In vivo permeability was assessed in male Sprague-Dawley rats treated for 6 days with ethanol, disulfiram, or saline alone or in combination. Bioavailability of naproxen was not affected by any treatment, whereas that of paclitaxel was increased upon acetaldehyde exposure. Although disulfiram has been shown to inhibit multidrug resistance-1 P-glycoprotein (P-gp) in vitro, our data demonstrate that the known P-gp substrate paclitaxel is not affected by coadministration of disulfiram. In conclusion, we demonstrate that acetaldehyde significantly modulates tight junctions and paracellular permeability in vitro as well as the oral bioavailability of low-molecular-weight hydrophilic probes and therapeutic molecules in vivo even when these molecules are substrates for efflux transporters. These studies emphasize the significance of ethanol metabolism and drug interactions outside of the liver.
A world unglued: simultanagnosia as a spatial restriction of attention

Simultanagnosia is a disorder of visual attention that leaves a patient's world unglued: scenes and objects are perceived in a piecemeal manner. It is generally agreed that simultanagnosia is related to an impairment of attention, but it is unclear whether this impairment is object- or space-based in nature. We first consider the findings that support a concept of simultanagnosia as deficit of object-based attention. We then examine the evidence suggesting that simultanagnosia results from damage to a space-based attentional system, and in particular a model of simultanagnosia as a narrowed spatial window of attention. We ask whether seemingly object-based deficits can be explained by space-based mechanisms, and consider the evidence that object processing influences spatial deficits in this condition. Finally, we discuss limitations of a space-based attentional explanation.
Vector-Embedded Karhunen-Loeve Transform and Its Application in Orientation Adaptive Coding of Images

In this paper, the theory and the design of a new class of orthogonal transforms are presented. The novel transform is derived from a correlation matrix in which an arbitrary orthonormal system is embedded. By embedding an orthonormal system designed empirically, we obtain the transform that is not only adapted for perceptual information but also possess statistical property like the Karhunen-Loève transform. Our main motivation is the application in block-based adaptive transform coding of images. We show a design example of the transform, which is adapted for directionality such as edges and lines. Using this transform, we perform orientation adaptive coding. Experimental results show that image coding using the transform is effective in rate-distortion sense and subjective quality. key words: Karhunen-Lo eve transform, orientation adaptive
Magnetic Fields in Dark Cloud Cores: Arecibo OH Zeeman Observations

We have carried out an extensive survey of magnetic field strengths toward dark cloud cores in order to test ambipolar-diffusion-driven and turbulence-driven models of star formation. The survey involved ~500 hr of observing with the Arecibo telescope in order to make sensitive OH Zeeman observations toward 34 dark cloud cores. Nine new probable detections were achieved at the 2.5 σ level; the certainty of the detections varies from solid to marginal, so we discuss each probable detection separately. However, our analysis includes all the measurements and does not depend on whether each position has a detection or just a sensitive measurement. Rather, the analysis establishes mean (or median) values over the set of observed cores for relevant astrophysical quantities. The results are that the mass-to-flux ratio is supercritical by ~2, and that the ratio of turbulent to magnetic energies is also ~2. These results are compatible with both models of star formation. However, these OH Zeeman observations do establish for the first time on a statistically sound basis the energetic importance of magnetic fields in dark cloud cores at densities of order 103–104 cm−3, and they lay the foundation for further observations that could provide a more definitive test.

Circulating Biomarkers of Inflammation, Antioxidant Activity, and Platelet Activation Are Associated with Primary Combustion Aerosols in Subjects with Coronary Artery Disease

Background Biomarkers of systemic inflammation have been associated with risk of cardiovascular morbidity and mortality. Objectives We aimed to clarify associations of particulate matter (PM) air pollution with systemic inflammation using models based on size-fractionated PM mass and markers of primary and secondary aerosols. Methods We followed a panel of 29 nonsmoking elderly subjects with a history of coronary artery disease (CAD) living in retirement communities in the Los Angeles, California, air basin. Blood plasma biomarkers were measured weekly over 12 weeks and included C-reactive protein (CRP), fibrinogen, tumor necrosis factor-α (TNF-α) and its soluble receptor-II (sTNF-RII), interleukin-6 (IL-6) and its soluble receptor (IL-6sR), fibrin D-dimer, soluble platelet selectin (sP-selectin), soluble vascular cell adhesion molecule-1 (sVCAM-1), intracellular adhesion molecule-1 (sICAM-1), and myeloperoxidase (MPO). To assess changes in antioxidant capacity, we assayed erythrocyte lysates for glutathione peroxidase-1 (GPx-1) and copper-zinc superoxide dismutase (Cu,Zn-SOD) activities. We measured indoor and outdoor home daily size-fractionated PM mass, and hourly pollutant gases, total particle number (PN), fine PM elemental carbon (EC) and organic carbon (OC), estimated secondary organic aerosol (SOA) and primary OC (OCpri) from total OC, and black carbon (BC). We analyzed data with mixed models controlling for temperature and excluding weeks with infections. Results We found significant positive associations for CRP, IL-6, sTNF-RII, and sP-selectin with outdoor and/or indoor concentrations of quasi-ultrafine PM ≤ 0.25 μm in diameter, EC, OCpri, BC, PN, carbon monoxide, and nitrogen dioxide from the current-day and multiday averages. We found consistent positive but largely nonsignificant coefficients for TNF-α, sVCAM-1, and sICAM-1, but not fibrinogen, IL-6sR, or D-dimer. We found inverse associations for erythrocyte Cu,Zn-SOD with these pollutants and other PM size fractions (0.25–2.5 and 2.5–10 μm). Inverse associations of GPx-1 and MPO with pollutants were largely nonsignificant. Indoor associations were often stronger for estimated indoor EC, OCpri, and PN of outdoor origin than for uncharacterized indoor measurements. There was no evidence for positive associations with SOA. Conclusions Results suggest that traffic emission sources of OCpri and quasi-ultrafine particles lead to increased systemic inflammation and platelet activation and decreased antioxidant enzyme activity in elderly people with CAD.
The Oxford-Dartmouth Thirty Degree Survey - II. Clustering of bright Lyman break galaxies: strong lu

We present measurements of the clustering properties of bright (L > L * ) z ∼ 4 Lyman break galaxies (LBGs) selected from the Oxford-Dartmouth Thirty Degree Survey (ODT). We describe techniques used to select and evaluate our candidates and calculate the angular correlation function, which we find best fitted by a power law, ω(θ) = A w θ -β with A w = 15.4 (with 0 in arcsec), using a constrained slope of β = 0.8. Using a redshift distribution consistent with photometric models, we deproject this correlation function and find a comoving r 0 = 11.4 +1.7 -1.9 h -1 100 Mpc in a Ω m = 0.3 flat A cosmology for i AB ≤ 24.5. This corresponds to a linear bias value of b = 8.1 +2.0 -2.6 (assuming σ 8 = 0.9). These data show a significantly larger r 0 and b than previous studies at z ∼ 4. We interpret this as evidence that the brightest LBGs have a larger bias than fainter ones, indicating a strong luminosity dependence for the measured bias of an LBG sample. Comparing this against recent results in the literature at fainter (subL * ) limiting magnitudes, and with simple models describing the relationship between LBGs and dark matter haloes, we discuss the implications on the implied environments and nature of LBGs. It seems that the brightest LBGs (in contrast with the majority subL * population) have clustering properties, and host dark matter halo masses, which are consistent with them being progenitors of the most massive galaxies today.
DYNAMIC MAGNETIC RESONANCE ELASTOGRAPHY

There is strong precedent in clinical medicine for the concept that tissue viscoelastic properties, assessed by palpation, are markedly affected by a variety of disease processes. Student physicians learn that the presence of a hard mass in the thyroid, breast, or prostate is suspicious for malignancy. Indeed, many tumors of these structures are still first detected by touch. It is not uncommon for surgeons at the time of laparotomy to palpate tumors that were undetected in preoperative imaging by CT, MRI, or ultrasound. None of these modalities provide the information about the elastic properties of tissue elicited by palpation. The elastic moduli of various human soft tissues vary over a wide range (more than 4 orders of magnitude). In contrast, most of the physical properties depicted by conventional medical imaging modalities are distributed over a much smaller numerical range.
