A Structural Equation Model of Nurses' Patient Safety Management Activities

Purpose: The purpose of this study was to build and test a model outlining the factors related to nurses' patient safety management activities. The exogenous variables were personal factor, job factor and organizational support. The endogenous factors were safety-related recognition, patient safety culture and patient safety management activities. Methods: A survey using a structured questionnaire was conducted among 500 nurses in Korea. The collected data were analyzed using PASW Statistics 18.0 and AMOS 20.0 programs. Results: Personal factors, job factors, safety-related recognition, and patient safety culture significantly affected nurses' patient safety management activities. Conclusion: These results suggest that patient safety accidents can be prevented by increasing the safety culture and safety related recognition. To improve the safety culture and safety related recognition, measures should be taken to reduce the turnover rate of career nurses and provide sufficient manpower allocation, education and policies.
Discovery of fourteen new ZZ Cetis with SOAR

We report the discovery of fourteen new ZZ Cetis with the 4.1 m Southern Astrophysical Research telescope, at Cerro Pachon, in Chile. The candidates were selected from the SDSS (Sloan Digital Sky Survey) DA white dwarf stars with Ten obtained from the optical spectra fit, inside the ZZ Ceti instability strip. Considering these stars are multi-periodic pulsators and the pulsations propagate to the nucleus of the star, they carry information on the structure of the star and evolution of the progenitors. The ZZ Cetis discovered till 2003 are mainly within 100 pc from the Sun, and probe only the solar vicinity. The recently discovered ones, and those reported here, may sample a distinct population as they were selected mainly perpendicular to the galactic disk and cover a distance up to 400 pc.
The Effects and Mechanism of Atorvastatin on Pulmonary Hypertension Due to Left Heart Disease

Background Pulmonary hypertension due to left heart disease (PH-LHD) is one of the most common forms of PH, termed group 2 PH. Atorvastatin exerts beneficial effects on the structural remodeling of the lung in ischemic heart failure. However, few studies have investigated the effects of atorvastatin on PH due to left heart failure induced by overload. Methods Group 2 PH was induced in animals by aortic banding. Rats (n = 20) were randomly divided into four groups: a control group (C), an aortic banding group (AOB63), an atorvastatin prevention group (AOB63/ATOR63) and an atorvastatin reversal group (AOB63/ATOR50-63). Atorvastatin was administered for 63 days after banding to the rats in the AOB63/ATOR63 group and from days 50 to 63 to the rats in the AOB63/ATOR50-63 group. Results Compared with the controls, significant increases in the mean pulmonary arterial pressure, pulmonary arteriolar medial thickening, biventricular cardiac hypertrophy, wet and dry weights of the right middle lung, percentage of PCNA-positive vascular smooth muscle cells, inflammatory infiltration and expression of RhoA and Rho-kinase II were observed in the AOB63 group, and these changes concomitant with significant decreases in the percentage of TUNEL-positive vascular smooth muscle cells. Treatment of the rats in the AOB63/ATOR63 group with atorvastatin at a dose of 10 mg/kg/day significantly decreased the mean pulmonary arterial pressure, right ventricular hypertrophy, pulmonary arteriolar medial thickness, inflammatory infiltration, percentage of PCNA-positive cells and pulmonary expression of RhoA and Rho-kinase II and significantly augmented the percentage of TUNEL-positive cells compared with the AOB63 group. However, only a trend of improvement in pulmonary vascular remodeling was detected in the AOB63/ATOR50-63 group. Conclusions Atorvastatin prevents pulmonary vascular remodeling in the PH-LHD model by down-regulating the expression of RhoA/Rho kinase, by inhibiting the proliferation and increasing the apoptosis of pulmonary arterial smooth muscle cells, and by attenuating the inflammation of pulmonary arteries.
Institutional sources of legitimacy for international organisations: Beyond procedure versus performance

Abstract This article addresses a significant gap in the literature on legitimacy in global governance, exploring whether, in what ways, and to what extent institutional qualities of international organisations (IOs) matter for popular legitimacy beliefs towards these bodies. The study assesses the causal significance of procedure and performance as sources of legitimacy, unpacks these dimensions into specific institutional qualities, and offers a comparative analysis across IOs in three issue areas of global governance. Theoretically, the article disaggregates institutional sources of legitimacy to consider democratic, technocratic, and fair qualities of procedure and performance. Empirically, it examines the effects of these institutional qualities through a population-based survey experiment in four countries in different world regions with respect to IOs in economic, security, and climate governance. The findings demonstrate that both procedure- and performance-related aspects of IO policymaking matter for popular legitimacy beliefs. This result holds across democratic, technocratic, and fair qualities of IO procedure and performance. Disaggregating the results by issue area indicates that a broader scope of institutional qualities are important for legitimacy beliefs in economic governance compared to security governance and, especially, climate governance. These findings suggest that propositions to reduce the institutional sources of IO legitimacy to single specific qualities would be misguided.
Full angle coverage in visual sensor networks

In this article, the problem of selection and configuration of visual sensors in Visual Sensor Networks (VSNs) is studied for coverage of the existing targets in the three-dimensional network area. It is assumed that visual sensors are capable of Pan-Tilt-Zoom (PTZ) ability and able to choose the covered area and desirable target through configuration of the angle of view in two horizontal and vertical dimensions and alteration of the enlargement scale. In order to solve the problem of selection and configuration, two methods according to Binary Integer Programming (BIP) and Greedy Search are presented to ensure to find the best solution and least calculation complexity respectively. Applying the proposed solutions, the problems of full angle coverage have been assessed using circular target model. The perceived results properly confirm the efficiency of the proposed method in terms of execution speed and decreasing the computation complexity.
Relay Selection Schemes for Dual-Hop Networks under Security Constraints with Multiple Eavesdroppers

In this paper, we study opportunistic relay selection in cooperative networks with secrecy constraints, where a number of eavesdropper nodes may overhear the source message. To deal with this problem, we consider three opportunistic relay selection schemes. The first scheme tries to reduce the overheard information at the eavesdroppers by choosing the relay having the lowest instantaneous signal-to-noise ratio (SNR) to them. The second scheme is conventional selection relaying that seeks the relay having the highest SNR to the destination. In the third scheme, we consider the ratio between the SNR of a relay and the maximum among the corresponding SNRs to the eavesdroppers, and then select the optimal one to forward the signal to the destination. The system performance in terms of probability of non-zero achievable secrecy rate, secrecy outage probability and achievable secrecy rate of the three schemes are analyzed and confirmed by Monte Carlo simulations.
DTMOS Technique for Low-Voltage Analog Circuits

In this paper, the application of dynamic threshold MOS (DTMOS) technique for low-voltage analog circuits is explored. The body terminal of PMOS transistors in bulk CMOS technology can be used as the forth terminal to enhance the performance of low-voltage analog circuits. To show the effectiveness of this technique, we have designed a continuous time common mode feedback (CMFB) circuit for a sub 1-V opamp and a new sub 1-V, 1-bit quantizer. A 0.8-V opamp with embedded CMFB and a 0.8-V, 1-bit quantizer for low-voltage DeltaSigma modulators are implemented in 0.18-mum CMOS technology. The simulation results as well as the measurement data of these blocks are presented in this paper
Infant and Toddler Type 1 Diabetes

OBJECTIVE To compare the effect of the prepubertal duration of diabetes on the occurrence of complications in two groups of patients after the same number of years of the disease. RESEARCH DESIGN AND METHODS This multicenter study enrolled 105 patients aged 16–40.3 years; 53 were prepubertal at diagnosis (aged 0–3) and 52 were pubertal (Tanner stage) and aged 9–14.9. The mean duration of disease was 19.8 and 19.5 years for prepubertal and pubertal patients, respectively. In all patients, retinal photographs were taken and centrally graded. Urinary albumin excretion (UAE; 86 case subjects), blood pressure (BP; 89 case subjects), and lifetime HbA1c (72 case subjects) were also evaluated. RESULTS The prevalence of diabetic retinopathy (DR) was higher in pubertal than in prepubertal patients, both for any grade DR (71 vs. 40%, P = 0.002) and for mild or more severe DR (P = 0.005). The prevalence of abnormal UAE was not different in the two groups. Hypertension was found only in three patients, all pubertal at diagnosis. In the small group with moderate-to-severe DR, lifetime HbA1c levels, as percentages above the upper normal reference value, were higher (P < 0.01) in prepubertal than in pubertal patients. CONCLUSIONS If diabetes is diagnosed in infants or toddlers and the prepubertal duration of diabetes is very long, the patients seem to be protected against DR. This protection disappears if lifetime metabolic control is bad. Instead, when onset is at puberty, the DR risk is higher and less dependent on metabolic control and may be influenced by age-related factors, such as BP.
Bug report, feature request, or simply praise? On automatically classifying app reviews

App stores like Google Play and Apple AppStore have over 3 Million apps covering nearly every kind of software and service. Billions of users regularly download, use, and review these apps. Recent studies have shown that reviews written by the users represent a rich source of information for the app vendors and the developers, as they include information about bugs, ideas for new features, or documentation of released features. This paper introduces several probabilistic techniques to classify app reviews into four types: bug reports, feature requests, user experiences, and ratings. For this we use review metadata such as the star rating and the tense, as well as, text classification, natural language processing, and sentiment analysis techniques. We conducted a series of experiments to compare the accuracy of the techniques and compared them with simple string matching. We found that metadata alone results in a poor classification accuracy. When combined with natural language processing, the classification precision got between 70-95% while the recall between 80-90%. Multiple binary classifiers outperformed single multiclass classifiers. Our results impact the design of review analytics tools which help app vendors, developers, and users to deal with the large amount of reviews, filter critical reviews, and assign them to the appropriate stakeholders.
UB at the NTCIR-12 SpokenQuery&Doc-2: Spoken Content Retrieval Using Multiple ASR Hypotheses and Syllables

The University at Buﬀalo (UB) team participated in the SpokenQuery&Doc task at the NTCIR-12, working on the Spoken Content Retrieval (SCR) subtask. We investigated the use of multiple ASR hypotheses (words) and subword units (syllables) for improving retrieval eﬀectiveness. We also compared the retrieval eﬀectiveness based on texts generated by two automatic speech recognition (ASR) engines, namely Julius and KALDI. Our experiment results showed that using multiple ASR hypotheses did not improve retrieval eﬀectiveness, while using ASR syllables alone led to lower mean average precision than using ASR words. Furthermore, ASR texts generated by the KALDI system resulted in signi(cid:12)cantly better retrieval eﬀectiveness than those by the Julius system. Future areas of work are discussed.
Composite vignettes of Swedish male and female professional handball players’ career paths

Abstract The aim of this study was to describe gender-specific career paths of Swedish professional handball players. A reanalysis of Ekengren et al. (2018) career interviews with nine male and nine female players led to creating two composite vignettes using the athletes’ own words, accounted for typical features in the male and female players’ career paths. Seven themes were identified in the analysis of the men’s transcripts and eight themes derived from the women’s transcripts. Further, the themes of both vignettes were aligned with career stages described in our previous study (Ekengren et al. 2018). The male players’ vignette is interpreted as a performance narrative congruent with elite handball culture that promotes performance success and profitable professional contracts. The female players’ vignette is more holistic, embracing handball, studies, motherhood, and how they ought to be as Swedish women. Recommendations for future research are provided.
Fragmentation and mass segregation in the massive dense cores of Cygnus X

Massive dense cores (MDCs) are the high-mass equivalent of the so-called dense cores in nearby star-forming regions. With typical sizes of 0.1 pc, they could form either a few high-mass stars, or a cluster of low-mass stars. We present high-angular resolution continuum observations obtained with the IRAM Plateau de Bure interferometer at 1.3 and 3.5 mm towards the six most massive and youngest (IR-quiet) dense cores in the Cygnus X complex. Located at only 1.7 kpc, the Cygnus X region offers the opportunity of reaching small enough scales (of the order of 1700 AU at 1.3 mm) to separate individual collapsing objects, and thus to observe and constrain the result of the fragmentation process. The cores are sub-fragmented with a total of 23 fragments inside 5 cores. Only the most compact MDC, CygX-N63, may host a single proto-stellar object with an envelope as massive as ˜60 M_ȯ. The fragments in the other cores have sizes and separations similar to low-mass pre-stellar condensations and Class 0 young stellar objects in nearby protoclusters, and are most probably self-gravitating objects (M > Mvir). In addition to CygX-N63, a total of 8 objects are found to be probable precursors of OB stars with their envelope masses ranging from 8.4 to 30 M_ȯ inside a FWHM of 4000 AU. The level of fragmentation is globally higher than in the turbulence regulated, monolithic collapse scenario, but it is also not as high as expected in a pure gravo-turbulent scenario where the distribution of mass is dominated by low-mass protostars/stars. Here, the fractions of the total MDC masses in the high-mass proto-stellar fragments are found to be as high as 37, 58, and 100% in CygX-N12, CygX-N53, and CygX-N63, respectively. These high fractions of mass in the proto-stellar fragments are also indicative of a high efficiency of core formation in the MDCs. The increase in the core formation efficiency as a function of average density in the MDCs is proposed to be caused by the increasing importance of self-gravity leading to gravitational collapse on the scale of the MDCs. At the same time, the observed MDCs tend to fragment into a few proto-stellar objects within their central regions. We are therefore probably witnessing the primordial mass segregation of clusters. The physical origin of the fragmentation into a few high-mass objects is not yet clear, and will be investigated in the future by studying the kinematics of the MDCs.
Male primary school teachers, masculinity and identity work in regional Australia

ABSTRACT This paper reports on the experiences of male primary school teachers in regional Australia. Drawing on 53 open-ended survey responses and interviews undertaken with five male teachers in Tasmania, the paper analyses their perspectives of their work and roles, and the additional labour of ‘career identity work’ through sport. For the men in this study, these additional roles find their antecedents in particular constructions of hegemonic masculinity where, on the one hand, they are expected to be ‘tough disciplinarians’ and, on the other, assumed to be ‘soft’ or ‘sinister’ for wanting to work with young children. Sport provided a safe context through which to manage such perceptions of their professional identity. Our study of teacher identities has wider significance for educators and policy makers to assist them understand and address the problem of low levels of recruitment and retention of male primary school teachers in Australia.
Implementation of a New Hybrid Method for Stemming of Arabic Text

paper, we propose a hybrid method that combines the application of three previously used techniques. These techniques deal with three key issues related to Arabic stemming including affix removal proposed by Kadri (1), dictionaries (2) and morphological analysis (3) (4) (5). Thus, when solving these problems these techniques are applied individually and independently to solve associated stemming problems, which requires some adjustments to be implemented on each one of them. Therefore, the main contribution of this experiment is to demonstrate the effectiveness of the hybrid method compared to other methods, and the choice of removing the suffix before prefix during the operation of Arabic stemming process.
Semiparametric Regression: Preface

To benefit from this book, a reader would need a solid background in statistical theory and distributions, as well a good handle on the mathematics. Although not required, it would also be helpful for the reader to have previous experience with classical regression and familiarity with S (or R) software to be able to use the S objects given at the end of each chapter. As such, the book seems appropriate for a graduate-level or advanced undergraduate statistics course in nonparametric regression. Most of the problems at the end of each chapter deal with the theoretical details or refinements of existing S objects to perform the analysis of data. A practitioner with experience using S can use the S objects to perform basic nonparametric regression analyses. Many of the figures in the book can be recreated with the code provided at the end of each chapter, which is useful for someone just learning the basics. The comments and notes for the portions of code are helpful for users wishing to modify the code to suit their particular purposes. At times, the book has the feel of a collection of tools rather than a sequential narrative, which makes it easier for the user to utilize a particular tool, assuming that he or she knows which tool he wants to use. I was surprised by the paucity of real data examples. Many of the examples are based on simulated datasets created to show a particular point, and the examples based on real data sets are usually meteorological or agricultural examples. To encourage a broader spectrum of application, I felt it would have been helpful to include a wider variety of examples. In addition, very few of the problems at the end of the chapters deal with analysis of real datasets. In fairness to Takezawa, many other related books (listed in the references) also lack real data examples. A minor criticism of this book deals with the figures. None of them have legends, few of them have descriptive titles, and those with multiple panels do not have informative labels. All of the information about the figures are contained in the captions, requiring a little more effort to determine the point of the figure in question. In addition, the figures are rarely on the page on which they are discussed, requiring a lot of page flipping, and there are a number of pages with …
Sedimentology and taphonomy of the Early to Middle Devonian plant-bearing beds of the Trout Valley Formation, Maine

The Trout Valley Formation of Emsian–Eifelian age in Baxter State Park, Maine, consists of fl uvial and coastal deposits that preserve early land plants (embryophytes). Seven facies are recognized and represent deposits of main river channels (Facies 1, 2), fl ood basin (Facies 4), storm-infl uenced nearshore shelf bars (Facies 3), a paleosol (Facies 5), and tidal fl ats and channels (Facies 6, 7). The majority of plant assemblages are preserved in siltstones and are allochthonous and parautochthonous, with only one autochthonous assemblage identifi ed in the sequence above an apparent paleosol horizon. Taphonomic analysis reveals that plant material within allochthonous assemblages is highly fragmented, poorly preserved, and decayed. Plant material within parautochthonous assemblages shows evidence of minimal transport, is well preserved, and shows signs of biologic response after burial. The one autochthonous assemblage contains small root traces. Trimerophytes (Psilophyton and Pertica quadrifaria), rhyniophytes (cf. Taeniocrada), and lycopods (Drepanophycus and Kaulangiophyton) are the most common taxa in estuarine environments. Psilophyton taxa, Pertica, cf. Taeniocrada, and Drepanophycus are found also in fl uvial settings. The presence of tidal infl uence in deposits where parautochthonous and autochthonous assemblages occur shows that these plants occupied coastal-estuarine areas. However, the effects on the growth and colonization of plants of the physical conditions (e.g., salinity) that exist in these settings in the Early to Middle Devonian are unknown.
Participatory Surveillance and Mathematical Models in Epidemiologic Research: Successes and Challenges

Influenzanet has been monitoring the activity of influenza-like illness (ILI) with the aid of volunteers via the internet in the Netherlands and Belgium since 2003 and in Portugal since 2005. In contrast with the traditional system of sentinel networks of mainly primary care physicians collected via the European Influenza Surveillance Scheme (EISS), since 2008 coordinated by the European Centre for Disease Control and Prevention (ECDC), Influenzanet obtains its data directly from the population. Any resident of the three countries can participate in Influenzanet by completing an application form on the appropriate websites — degrotegriepmeting.nl in the Netherlands and Belgium, gripenet.pt in Portugal — which contain various medical, geographic and behavioral questions. Participants report weekly on the website any symptoms they have experienced since their last visit. ILI incidence is determined on the basis of a uniform case definition. In the 2006–2007 season, 19,623 persons participated in Influenzanet in the Netherlands, 7,025 in Belgium, and 3,118 in Portugal. The rise, peak and decline of ILI activity occurred at similar times according to Influenzanet and ECDC. However, ILI attack rates in the Netherlands (8.7%), Belgium (8.1%) and Portugal (7.3%) were remarkably more similar in Influenzanet than in ECDC (0.8%, 3.9%, and 0.6% respectively). Monitoring ILI activity with the direct participation of volunteers provides similar incidence curves compared to the traditional system coordinated by ECDC. Whereas ECDC provides an established system whose data is validated by virology tests, Influenzanet is a fast and flexible monitoring system whose uniformity allows for direct comparison of ILI rates between countries. A current objective of Influenzanet is to engage more European countries.
