“Talking the walk to walk the talk”: A qualitative report of patients’ experiences of undergraduate nursing students using motivational interviewing

Background and objective: Motivational interviewing (MI) is a communication style adopted by health professionals to support patient-centered decision making about behavior change. Little is known about how patients respond to this relational approach when it is used by baccalaureate students. Thus, the study aim was to explore how patients experience MI by undergraduate nursing students when it is used to support health behavior change for vascular risk reduction. Methods: A focused ethnography was undertaken to explore the tacit and explicit dimensions of patient health behavior change as it evolved through MI encounters with nursing students. The research setting was a post-secondary institution in Canada and comprised a sample of 16 patients who received MI by the nursing students, 2 clinical instructors who teach MI, and 20 third-year nursing students who used MI as part of a 13-week community based clinical experience. Data sources included participant observations, field notes and one-to-one interviews. Results: Patients described their encounters with nursing students using MI as novel, relative to typical instances with health providers, and foundational to supporting lifestyle change. The patients’ overall experience is characterized by a thematic arc of ‘talking the walk to walk the talk’. Motivational interviewing helped patients integrate personalized information about the meaning of vascular health, deliberate on options and initiate lifestyle changes to promote health. In most cases, patients translated knowledge and experience from their motivational encounters with nursing students into subsequent health management activities. Conclusions: Through their experiences of nursing students using MI, patients understood the personal implications of vascular health, took action on relevant goals and applied lessons learned to future behavior change efforts. The results contribute new information about how patients respond to MI from baccalaureate nursing students and reinforce current understanding of how change talk contributes to subsequent change behavior.
Exploring The Most Frequent Heuristic for (Semi)-Structured Retrieval

Keyword query interfaces for databases (K QIs) provide easy access to data, but often suffer from ranking quality problems. Since users do not generally specify the schema elements in keyword queries, an important challenge to build an effective KQI is to find the desired schema elements for a given keyword query. One popular heuristic, called the most frequent heuristic, assumes that the schema elements where the query terms appear more frequently are the desired schema elements for the query terms. In this paper, we have performed an extensive empirical evaluation using keyword queries form a Web search engine. We show that the most frequent heuristic is not generally effective and in most cases users prefer the schema elements where the query terms appear quiet infrequently.
Effect of silver nitrate on in vitro root formation of Gentiana lutea

Gentiana lutea (Gentianaceae) is a valuable, protected species, included in the Red Book of Bulgaria. Microbial contamination is one of the most critical and often encountered problems in plant tissue cultures. The influence of silver nitrate (AgNO3) on in vitro rooting of G. lutea was examined. Considerable limitation of late bacterial contamination and improved in vitro rooting of plants were achieved on half strength MSR2 rooting medium supplemented with IBA (1 mg/l) and AgNO3 (1 mg/l). The optimization of this medium provided a high degree of rooting (90%) and lack of bacterial contamination. A maximum plant height (2.5 cm), number of roots/plant (4.5) with mean length 1.5 cm were obtained on ½ MSR2 medium after four weeks of culture. The effect of different mixture substrate during acclimatization stage was also studied. Best response (65%) was obtained in peat: perlite: sand (2:1:1 v/v/v), after eight weeks of transplantation in ex vitro conditions. This technique can be effectively used for in vitro rooting of G. lutea.
Damage detection in beams using wavelet transform on higher vibration modes

Technical difficulties prevented so far wider applications of higher mode shapes in damage detection. Yet these modes carry on a lot of, so much needed, information on damage inflicted to a structure. However, recent scanning laser-based vibration measurement techniques allow one to utilize these higher modes in damage detection effectively. This paper deals with the wavelet-based damage detection technique on a cantilever beam with damage in the form of a single notch of depth 20%, 10% and 5% of the beam height. The purpose of the study is to present the results of experimental and numerical analyses of damage detection based on higher order modes. The first eight modes are considered and the influence of the mode order on the effectiveness of damage detection by the continuous wavelet transform is analysed in detail.
Enhancements Tools for a Digital Library pdfJbIm and pdfsign

This paper describes several innovative PDF document enhancements and tools that can be used when building a digital library. The main result presented in this paper is the PDF re-compression tool, developed using the jbig2enc encoder called pdfJbIm. This re-compression tool enables the size of the original bitonal PDFs to be, on average, downsized by one third. Some modifications to the jbig2enc encoder that increase the compression ratio even further are also described here. Together with another program, the pdfsizeopt.py by Péter Szabó, we have managed to decrease PDF storage size to such an extent that the transmission needs of a digital library were significantly reduced. We report the storage saving results that we have achieved on The Czech Digital Mathematics Library DML-CZ — we have downsized the PDF corpus to 43% of its original size. We also describe pdfsign tool for batch digital signature stamping of PDF documents.
Diuraphis noxia: reproductive behaviour in Argentina

Diuraphis noxia (Kurdjumov) (Rhynchota Aphididae) is an important aphid pest of wheat and barley crops in many countries. Populations of Russian wheat aphid (RWA) from different origins show different reproductive behaviour, but the situation in Argentina was unknown. The aim of the current research was to determine the reproductive behaviour of RWA in Argentina based on samples from populations at six different localities with contrasting land use, altitude and climate. RWA were collected from cultivated and wild grasses from February to December 2005, and 10-15 colonies of aphids were established by collecting parthenogenetic adult females from each population. These colonies were kept under natural conditions at La Plata (36°36′ South Latitude) from 21 December 2005 to 21 December 2007. In more than half of the colonies, oviparous females and eggs were recorded in both years when temperatures were low and the photoperiod either short or increasing and relatively long. Consequently, oviparous females and eggs were recorded from early autumn (April) until the following spring (October), when day length was 11:33 and 13:44 hours, respectively. In both years the temperature and the altitude at the place of origin were highly correlated with the timing of sexual development. The production of eggs enables RWA to survive periods of adverse conditions and generate variability. Thus, by reproducing sexually, RWA may be able to adapt to new environmental conditions and give rise to new, more aggressive biotypes, which can overcome the current resistant varieties of wheat.
Towards a supervised rescoring system for unstructured data bases used to build specialized dictionaries

This article proposes the architecture for a system that uses previously learned weights to sort query results from unstructured data bases when building specialized dictionaries. A common resource in the construction of dictionaries, unstructured data bases have been especially useful in providing information about lexical items frequencies and examples in use. However, when building specialized dictionaries, whose selection of lexical items does not rely on frequency, the use of these data bases gets restricted to a simple provider of examples. Even in this task, the information unstructured data bases provide may not be very useful when looking for specialized uses of lexical items with various meanings and very long lists of results. In the face of this problem, long lists of hits can be rescored based on a supervised learning model that relies on previously helpful results. The allocation of a vast set of high quality training data for this rescoring system is reported here. Finally, the architecture of sucha system, an unprecedented tool in specialized lexicography, is proposed.
Handlingsplan for storskala anvendelse af elektrolyse i Danmark

Elektrolyse af vand er en kemisk proces, som er blevet anvendt til industrielle formål i mange år. Interessen for brug af energisektoren er stor, men udrulningen er kompleks og går for langsomt. Dette skal ændres inden for en overskuelig fremtid, både fordi behovet for brint til den tunge transport er stor, og fordi lagring af elektricitet ved hjælp af brint kan give os mulighed for at bruge mere fluktuerende vedvarende energi i systemet. Lagring af elektroner i kemisk energi via elektrolyse udgør et alternativ til direkte lagring af elektricitet eller varmelagring. energisystemet i mindre skala. Herved kan målsætningen 100% vedvarende energi i 2050 blive realiseret, hvor der kan være brug for flere hundrede MW elektrolyse, hvis man følger mange af de scenarioer der er lavet for 2050. I disse anses elektrolyse nemlig for at være en nødvendigt imødekomme behovet for flybrændstof alternative brændstoffer baseret vedvarende teknologi. Pilottests af parallelt med af at biobrændstof kan Etableringen af konsistent database indeholdende data for ydevene og produktionscyklusser under anvendelse af de nye brændstofferne for at kunne føre tilsyn med mulighederne for teknologien.
Teaching compound words to a spelling-disabled child via Smart Notebook Technology: Α case study approach

The case-study aims to examine the effectiveness of training of morphological structure on the spelling of compounds by a spelling-disabled primary school student. The experimental design of the intervention was based on the word-pair paradigm and included a pre-test, a training program and a post-test (n= 50 pairs). The Training Program aimed to offer systematic, targeted and step-by-step instruction of morphological decomposition of words to the student and delivered via the Smart Notebook educational software. The intervention had a substantial impact in enhancing the spelling of compounds by the individual. Especially, instructional gains were statistically significant, and generalized substantially to untrained but analogous words and pseudowords in terms of structure and common stems. These findings are particularly important for the development of alternative approaches to the educational interventions of individuals with spelling difficulties and developmental dyslexia, and are consistent with the experimental literature.
Genetic relationship and allozyme expression of insecticide susceptible and resistant helopeltis theivora populations from Peninsular Malaysia

Helopeltis theivora is a known pest of cocoa and tea in Malaysia. Several mechanisms of insecticide resistance have been proposed such as reduction in the sensitivity of target sites, metabolic detoxification of pesticides and decreased penetration or translocation of pesticides. Polyacrylamide gel electrophoresis (PAGE) was used to determine the metabolic enzymes involved in the development of resistance in Helopeltis theivora. Adults of Helopeltis theivora were collected from three geographical locations namely Bukit Cheeding (Banting, Selangor), Sg. Palas (Cameron Highlands) and MARDI (Cameron Highlands, Pahang). In total, 25 enzymes were screened for polymorphisms and 8 enzymes were detectable in H. theivora. The dendogram resulting from the cluster analysis grouped the infrequently sprayed Banting and the MARDI populations together while the intensively sprayed Sg. Palas population clustered by itself.
Performance investigation of three-phase and single-phase e-core hybrid excitation flux switching motor for hybrid electric vehicle applications

Research and development of hybrid electric vehicles (HEVs) which integrate battery-based electric motor with conventional internal combustion engine (ICE) has flourished since the last decade given their commitment in reducing green house effect and global warming. Although IPMSM is deemed as an effective electric motor used in HEVs, it’s have some limitations such as distributed armature windings, uncontrollable permanent magnet (PM) flux, and higher rotor mechanical stress remain to be resolved. A new candidate of hybrid excitation flux switching motor (HE-FSM) at various rotor pole number such as 6S-4P, 6S-5P, 6S-7P, 6S-8P, 6S-14P, 4S-4P, 4S-6P 4S-8P and 4S-10P E-Core HE-FSMs, built on concentrated armature and DC field excitation (DC-FE) coil windings, variable flux capability with robust rotor structure which is suitable for high-speed operation is proposed and examined in this thesis. In this research, a commercial FEA solver, JMAG-Studio 13.0 released by JSOL Corporation, is used for 2D-FEA. JMAG was released as a tool to support design for devices such as motors, actuators, circuit components, and antennas. Design feasibility studies of E-Core HE-FSMs and deterministic optimization method have been applied to improve the proposed machine. The goal of this design is to achieve torque and power higher than 303Nm, 123kW and 101Nm, 41kW for three-phase and single-phase, respectively, so as to compete with the IPMSM commonly used in HEV. As a result, the maximum torque and power of the final design three phase and single-phase E-Core HE-FSMs are 313.29Nm, 260kW, 233Nm and 43.42kW respectively. Positively, the proposed HE-FSM has proved to be a good candidate for efficient and safe HEV drive.
Stabilizing predictive visual feedback control for fixed camera systems

This paper investigates vision-based robot control via a receding horizon control strategy for fixed camera systems, as stabilizing predictive visual feedback control. First, a visual motion robot error system with a fixed camera configuration is reconstructed in order to improve estimation performance. Next, stabilizing receding horizon control for three-dimensional visual feedback systems, which are highly nonlinear and relatively fast systems, is proposed. The stability of the receding horizon control scheme is guaranteed by using a terminal cost derived from an energy function of the visual motion robot error system. Furthermore, simulation and actual nonlinear experimental results are assessed with respect to stability and performance. © 2011 Wiley Periodicals, Inc.

HE 0017+0055: A probable pulsating CEMP-rs star and long-period binary

A large fraction of the carbon-enhanced, extremely metal-poor halo giants ([Fe/H] 1.9 dex and [Eu/Fe] = 2.3 dex, HE 0017+0055 is a CEMP-rs star. We used the derived atmospheric parameters and abundances to infer HE 0017+0055 evolutionary status from a comparison with evolutionary tracks. Results. HE 0017+0055 appears to be a giant star below the tip of the red giant branch. The s-process pollution must therefore originate from mass transfer from a companion formerly on the AGB, which is now a carbon-oxygen white dwarf (WD). If the 384 d velocity variations are attributed to the WD companion, its orbit must be seen almost face-on, with i ~ 2.3°, because the mass function is very small: f(M1,M2) = (6.1 ± 1.1) × 10-6M⊙. Alternatively, the WD orbital motion could be responsible for the long-term velocity variations, with a period of several decades. The 384 d variations should then be attributed either to a low-mass inner companion (perhaps a brown dwarf, depending on the orbital inclination), or to stellar pulsations. The latter possibility is made likely by the fact that similar low-amplitude velocity variations, with periods close to 1 yr, have been reported for other CEMP stars in a companion paper. A definite conclusion about the origin of the 384 d velocity variations should however await the detection of synchronous low-amplitude photometric variations.
EXAMINING THE SUPERIORITY OF COMPREHENSIVE INCOME TO NET INCOME AS A MEASURE OF FIRM PERFORMANCE

In this study we investigate the relative ability of comprehensive income and net income to summarize firm performance as reflected in stock returns. We also examine which comprehensive income adjustments improve the ability of income to summarize firm performance. We also investigate this claim that income measured on a comprehensive basis is a better measure of firm performance than other summary income measures. The results do not show that comprehensive income is superior to net income for evaluating firm performance on the basis of stock return and price. Except for investment industrial group, In Tehran Stock Exchange, we found no evidence that comprehensive income for firm performance evaluation on the basis of cash flows prediction is superior to net income. While, we found the better results for the state companies (only in other companies group), i.e., firm performance evaluation on the basis of cash flows prediction using comprehensive income is superior to net income. Collectively, our results provide some weak evidence that show comprehensive income adjustments improve ability of income for reflecting firm performance.
Measurement of Correlation Between Flow Density, Velocity, and Density*velocity(sup 2) with Far Field Noise in High Speed Jets

To locate noise sources in high-speed jets, the sound pressure fluctuations p', measured at far field locations, were correlated with each of radial velocity v, density rho, and phov(exp 2) fluctuations measured from various points in jet plumes. The experiments follow the cause-and-effect method of sound source identification, where correlation is related to the first, and correlation to the second source terms of Lighthill's equation. Three fully expanded, unheated plumes of Mach number 0.95, 1.4 and 1.8 were studied for this purpose. The velocity and density fluctuations were measured simultaneously using a recently developed, non-intrusive, point measurement technique based on molecular Rayleigh scattering. It was observed that along the jet centerline the density fluctuation spectra S(sub rho) have different shapes than the radial velocity spectra S(sub v), while data obtained from the peripheral shear layer show similarity between the two spectra. Density fluctuations in the jet showed significantly higher correlation, than either rhov(sub 2) or v fluctuations. It is found that a single point correlation from the peak sound emitting region at the end of the potential core can account for nearly 10% of all noise at 30 to the jet axis. The correlation, representing the effectiveness of a longitudinal quadrupole in generating noise 90 to the jet axis, is found to be zero within experimental uncertainty. In contrast rhov(exp 2) fluctuations were better correlated with sound pressure fluctuation at the 30 location. The strongest source of sound is found to lie at the centerline and beyond the end of potential core.
Scales of coastal heterogeneity and benthic intertidal species richness, diversity and abundance

Species richness, diversity, total biomass of the benthic macrofauna and macroflora and the biomass of the 2 dominant taxa (Fucus spp and Myt~ lus eduhs) were examined in relation to coastal heterogeneity at different scales in the intertidal zone The sampling design included randomness at all scales and replication of treatments A 103 km portion of the south shore of the St Lawrence Estuary, Canada, was divided into 1 km stretches of shore (stations)-the large scale-which were classified using a shore heterogeneity index (SHI) into 3 categories (low, medium and high) Species nchness was qualitatively evaluated for each station and substratum heterogeneity on a 100 m (medium scale) was measured as covariate At the smallest scale 4 types of surface (smooth, crevices of 1, 10 and 20 cm) were quantitatively sampled Species nchness tended to increase with SHI category but this tendency was not statistically s~gnificant A multiple regression analysis was carned out to f ~ n d which scale of heterogeneity was the most significant for defining species richness Diversity in types of surface did not vary significantly among SHI categones Our results show that large-scale heterogeneity explained a higher proportion of the vanance in species nchness than substratum heterogeneity on a 100 m scale No statistically significant difference was found in total biomass M edulrs and Fucus spp biomass or percent cover among the SHI categones At the small scale (types of surface), the abundance increased significantly from smooth surfaces to 20 cm crevices except for mussels, where abundance was higher in 10 cm crevices The types of surface explained 42% of the variation in total biomass and 21 % of that in Fucus spp biomass Variation in percent cover was explained by the types of surface (40%) and to a lesser extent by the SHI (? %) The present study showed that the scales which influenced abundance were smaller than 20 cm in the intertidal zone Thus our results indicated that 2 distinct spatial scales explained the vanab~lity within the same marine intertidal community, i e vanability in species nchness (scale o! 1 km) and in abundance (types of surface, scale of 520 cm)
Ring-hydroxylating dioxygenases involved in PAH biodegradation : structure, function, biodiversity

The first step in the biodegradation of PAHs by aerobic bacteria is catalyzed by metalloenzymes known as ring-hydroxylating dioxygenases (RHDs). Because of the hydrophobic nature and chemical resistance of PAHs, their initial attack by RHDs is a difficult reaction, which is critical to the whole degradation process. This chapter gives an overview of the current knowledge on the genetics, structure, catalytic mechanism and diversity of RHDs involved in PAH degradation. In the past decade, the crystal structures of 10 RHDs have been determined, giving insights into the mechanism of substrate recognition and regioselectivity of dioxygenation. The reaction catalyzed by the archetypal naphthalene dioxygenase has been investigated in detail, thus providing a better understanding of the RHD catalytic mechanism. Studies on the catabolic genes responsible for PAH degradation in several bacterial taxa have highlighted the great phylogenetic diversity of RHDs. The implementation of culture-independent methods has afforded means to further explore the environmental diversity of PAH-degrading bacteria and RHDs. Recent advances in this field now allow the in situ identification of bacteria responsible for pollutant removal. Further biotechnological developments based on microarrays and functional metagenomics should lead to the conception of molecular tools useful for the bioremediation of PAH-contaminated ecosystems.
The Effects of Graduate-Student Unionization on Stipends

Beginning in the 1970s, graduate assistants have organized labor unions. Presently, 38 universities have a graduate-student union. However, the effect graduate-student unions have on wages, wage variance, health benefits, and organizational structure is unknown. This study uses data from the Chronicle of Higher Education and government data to estimate the economic effects of unionization. By using a multilevel model is used to control for intra-university correlation of wages, this study concludes graduate unions are effective at raising stipends, but ineffective at lowering fees, providing health-care coverage, and lowering intra-university wage variance.
