Insomnia induced by night shift work is associated with anxiety, depression, and fatigue, among critical care nurses

Objectives: The general purpose of this study was to investigate the effect of night shift work (NSW) on insomnia, anxiety, depression, and fatigue, among nurses working in critical care units. Methodology: Five hundred and twelve critical care nurses were recruited from the Intensive Care Units (ICU), Emergency Rooms (ER) and Operation Rooms (OR) from six major hospitals in Amman, Jordan. Participants singed an informed consent and answered, sociodemographic questionnaire, in addition to Hospital Anxiety and Depression Scale, Fatigue Severity Scale, and Insomnia Severity Index. Results: Critical care nurses who were working on night shift have higher levels of insomnia, depression, anxiety, and fatigue than nurses working on day shift or temporary night. Furthermore, female and ICU nurses experienced more fatigue than male nurses and nurses from OR and ER respectively. There was a dose-response relationship between the number of night that nurses work in the previous year with their (insomnia, depression, and fatigue levels) Conclusion: Night shift work induced insomnia for nurses working in critical care units which increased their anxiety, depression and fatigue levels. This has negative consequences in their health 138 Mohannad Eid AbuRuz and Haneen M. Abu Hayeah and the care provided to the patients. Health care employers should use alternative methods to help nurses overcome this issue.
Multigene phylogenies reveal that red band needle blight of Pinus is caused by two distinct species of Dothistroma, D. septosporum and D. pini

The red band needle blight fungus, Dothistroma septosporum is a widely distributed pathogen of many pine species. Three morphological varieties of this pathogen have been described based on differences in conidial length. However, contro- versy exists as to whether spore size represents an adequate characteristic to distinguish between forms of D. septosporum. The aim of this investigation was to consider the phylogenetic relationships between D. septosporum isolates from different coun- tries. An additional objective was to determine whether comparisons of DNA sequence data support the morphological varie- ties recognized for this species. DNA from portions of the nuclear ribosomal internal transcribed spacer (ITS), �-tubulin and elongation factor 1-� genes were sequenced and analysed for isolates from 13 different countries representing five continents. Results show that isolates of the pathogen encompass two divergent lineages representing distinct phylogenetic species. One phylogenetic species (Lineage I) is found worldwide, while the other (Lineage II), is restricted to the North-Central U.S.A. The names D. pini and D. septosporum are available for these species. The former name should apply to the phylogenetic species currently known only from the United States. The latter fungus has a worldwide distribution and is the causal agent of the serious disease known as red band needle blight that has damaged exotic plantations of Pinus radiata in the Southern Hemi- sphere. A PCR-restriction fragment length polymorphism (RFLP) diagnostic protocol is described that distinguishes between all the currently known Dothistroma species. The previous classification of D. septosporum isolates into different varieties based on morphology is inconsistent and not supported by our DNA analyses. We therefore reject further use of varietal names in Dothistroma.
Measuring marginal predation in animal groups

Predation is a major pressure that shapes animal sociality, but predation risk is not homogenous within groups. Animals located on the group edge typically face an increased threat of predation, although different patterns have been reported. We created a simulation model to determine how changes in predator attack distance and prey density influence predation in relation to within-group spatial position. At large attack distances, peripheral animals were attacked far more than central animals. At relatively short attack distances, central individuals were attacked almost as often as peripheral animals. We used 6 different methods to classify within-group spatial position in our simulations and tested which methods were the best predictors of predation risk at different parameter values. The minimum convex polygon and angle of vulnerability methods were the best predictors of predation risk at large and medium attack distances, respectively. At relatively short attack distances, the nearest neighbor distance and neighbor density methods were the best predictors of predation risk. These patterns demonstrate that the threat of marginal predation is dependent on the behavior of predators and that for some predator--prey systems, marginal predation is predicted to be insignificant. We predict that social prey animals should change antipredatory behavior, such as vigilance, within-group spacing, and within-group spatial choice based on the relative distances at which their predators attack. These results demonstrate the importance of incorporating the behavior of predators in empirical studies and predator--prey models. Copyright 2011, Oxford University Press.
A New Surface Model for Cyclone–Anticyclone Asymmetry

Cyclonic vortices on the tropopause are characterized by compact structure and larger pressure, wind, and temperature perturbations when compared to broader and weaker anticyclones. Neither the origin of these vortices nor the reasons for the preferred asymmetries are completely understood; quasigeostrophic dynamics, in particular, have cyclone‐anticyclone symmetry. In order to explore these and related problems, a novel small Rossby number approximation is introduced to the primitive equations applied to a simple model of the tropopause in continuously stratified fluid. This model resolves dynamics that give rise to vortical asymmetries, while retaining both the conceptual simplicity of quasigeostrophic dynamics and the computational economy of two-dimensional flows. The model contains no depth-independent (barotropic) flow, and thus may provide a useful comparison to two-dimensional flows dominated by this flow component. Solutions for random initial conditions (i.e., freely decaying turbulence) exhibit vortical asymmetries typical of tropopause observations, with strong localized cyclones, and weaker diffuse anticyclones. Cyclones cluster around a distinct length scale at a given time, whereas anticyclones do not. These results differ significantly from previous studies of cyclone‐anticyclone asymmetry in the shallow-water primitive equations and the periodic balance equations. An important source of asymmetry in the present solutions is divergent flow associated with frontogenesis and the forward cascade of tropopause potential temperature variance. This thermally direct flow changes the mean potential temperature of the tropopause, selectively maintains anticyclonic filaments relative to cyclonic filaments, and appears to promote the merger of anticyclones relative to cyclones.

The Cyclicality of Wages and Match Quality ∗

I estimate the cyclicality of real wages for job stayers, hires from employment and from unemployment, using an administrative matched employer-employee dataset from Germany. I find that the wages of new hires appear to be less procyclical than the wages of job stayers. I propose an explanation based on countercyclical selection on match quality: when aggregate productivity is low, worker-firm matches have to be unusually productive to warrant job creation. The presence of the match quality selection effect is supported by the relationship between the initial aggregate conditions and subsequent risk of separation: jobs started when unemployment is high are at a decreased risk of ending with a separation to unemployment, which suggests that they are positively selected. Finally, I show that a Diamond-Mortensen-Pissarides search and matching model with match-specific productivity and turnover costs is consistent with empirical findings.

Wave Concept Iterative Procedure Analysis of Patch Antennas on Nanostructured Ceramic Substrates

The wave concept iterative procedure (WCIP) is proposed to analyze rectangular and circular patch antennas on nanostructured ceramic substrates. Principles of WCIP are described and advantages are emphasized. The analysis of microstrip antennas on double layered substrates is performed in space and spectral domains. In addition, Fast Fourier Transformation (FFT) is used to improve the efficiency of the method. WCIP simulated results are compared to HFSS software ones. A good agreement is observed .
National Constitution: A Foundation for Exemplary Leadership andDevelopment in African Transition Economies

National constitution: A foundation for exemplary leadership and development in African transition economies. The study sets out to accomplish these objectives to: investigate the causes of the low speed accumulation of human capital; ascertain why Nigerian leaders make disastrous choices resulting in failing health and educational system as well as examine why Military Decree No 24 CFRN (1999) continues to serve as CFRNA in a democratic dispensation. The study used a secondary instrument for data collection from relevant journals, magazines, books and internet. The gap in literature shows that most African States are still chained to Military Decrees as their respective constitutions. The supreme court over rules itself, consequently any sovereign, military or civilian, can overrule itself. The findings are that: the military personnel attained minimal educational level, consequently, its decree No 24 CFRN (1999) perpetuates illiteracy; and the military rule left in its wake, a sad legacy of human rights violations, stunted national growth a corporatism and static state, increased corruption and posing the greatest threat to democracy and national integration. Based on these findings, the recommendations are that: Decree No 24 CFRNA is being stretched beyond its usefulness: This paper advocates for a transition period for the formulation of a progressive democratic constitution and the raising of the educational level to a good first Degree from a recognized university for membership of the National Assembly. The conclusion is that Decree 24 CFRNA (1999) and its – up to at least school certificate level turns retired wealthy military generals and officers as unprepared political leaders and actors politically. The Nigerian culture of illiteracy is the exact symbol of its laws.
Document Clustering using Multi-objective Genetic Algorithm with Different Feature Selection Methods

Multi-objective genetic algorithm for the document clustering is proposed in this paper. The researches of the document clustering using k-means and genetic algorithm are much in progress. k-means is easy to be implemented but its performance much depends on the first stage centroid values. Genetic algorithm may improve the clustering performance but it has the disadvantage to trap in the local minimum value easily. However, Multi-objective genetic algorithm is stable for the performances and avoids the disadvantage of genetic algorithms in our experiments. The several feature selection methods are applied to and compared with those clustering algorithms. Consequently, Multiobjective genetic algorithms showed about 20% higher performance than others.
The Canady Helios Cold Plasma Scalpel Significantly Decreases Viability in Malignant Solid Tumor Cells in a Dose-Dependent Manner

To determine appropriate treatment doses of cold atmospheric plasma (CAP), the Canady Helios Cold Plasma Scalpel was tested across numerous cancer cell types including renal adenocarcinoma, colorectal carcinoma, pancreatic adenocarcinoma, ovarian adenocarcinoma, and esophageal adenocarcinoma. Various CAP doses were tested consisting of both high (3 L/min) and low (1 L/min) helium flow rates, several power settings, and a range of treatment times up to 5 min. The impact of cold plasma on the reduction of viability was consistently dose-dependent; however, the anti-cancer capability varied significantly between cell lines. While the lowest effective dose varied from cell line to cell line, in each case an 80–99% reduction in viability was achievable 48 h after CAP treatment. Therefore, it is critical to select the appropriate CAP dose necessary for treating a specific cancer cell type.
Atlantic versus Indo‐Pacific influence on Atlantic‐European climate

The influence of the Atlantic and Indo‐Pacific oceans on Atlantic‐European climate is investigated by analyzing ensemble integrations with the atmospheric general circulation model ECHAM4 forced by anomalous sea surface temperature and sea ice conditions restricted to the Atlantic (AOGA) and Indo‐Pacific (I+POGA) oceans. The forcing from both the Indo‐Pacific and Atlantic oceans are important for the generation of the sea level pressure (SLP) variability in the Atlantic region in the boreal winter season. Over the North Atlantic the SLP response in the I+POGA experiment projects on the North Atlantic Oscillation, while it projects on the East Atlantic Pattern in the AOGA experiment. In both experiments (I+POGA and AOGA) a quadrupole‐type 500 hPa height anomaly pattern is simulated which emerges from the tropical Pacific and Atlantic oceans, respectively. In boreal summer the influence of the Atlantic Ocean dominates the SLP response in the Atlantic region. The tropical North Atlantic is a key region in forcing the SLP response over the Caribbean Sea in this season.
Computer Vision-Based Fall Detection Methods Using the Kinect Camera: A Survey

Disabled people can overcome their disabilities in carrying out daily tasks in many facilities [1]. However, they frequently report that they experience difficulty being independently mobile. And even if they can, they are likely to have some serious accidents such as falls. Furthermore, falls constitute the second leading cause of accidental or injury deaths after injuries of road traffic which call for efficient and practical/comfortable means to monitor physically disabled people in order to detect falls and react urgently. Computer vision (CV) is one of the computer sciences fields, and it is actively contributing in building smart applications by providing for image\video content “understanding. ” One of the main tasks of CV is detection and recognition. Detection and recognition applications are various and used for different purposes. One of these purposes is to help of the physically disabled people who use a cane as a mobility aid by detecting the fall. This paper surveys the most popular approaches that have been used in fall detection, the challenges related to developing fall detectors, the techniques that have been used with the Kinect in fall detection, best points of interest (joints) to be tracked and the well-known Kinect-Based Fall Datasets. Finally, recommendations and future works will be summarized.
Evaluation of Serum Ca, Mg, Cu, Fe, Zn and Mn in Conversion Disorder Patients

The aim of the study was to determine the concentration of serum Ca, Mg, Cu, Fe, Zn and Mn in Bangladeshi conversion disorder patients compared to control subjects and to correlate the changes, if any, with different socio-demographic factors and nutritional status. Forty five conversion disorder patients were randomly recruited. Forty five healthy control subjects were also recruited by matching the socio-demographic status to that of the patients. Blood samples were analyzed to determine the concentration of serum Ca, Mg, Cu, Fe, Zn and Mn using atomic absorption spectroscopy. Except for Mg, the concentrations of the other elements (Cu, Fe, Zn, Ca, and Mn) decreased in patients compared to control, but the changes were not statistically significant ( p > 0.05). Serum Mg level increased insignificantly in patients ( p > 0.05). No significant relationship was found between the sociodemographic variables and serum Ca, Mg, Cu, Zn and Mn levels, except for serum Fe, where a significant negative correlation was found between serum Fe level and BMI ( r = –0.428; p = 0.023). Key words : Conversion disorder patients; serum elements; socio-economic status DOI: http://dx.doi. org/10.3329/dujps.v9i2. 7896 Dhaka Univ. J. Pharm. Sci. 9 (2): 119-124, 2010 (December)
Molecular and cytogenetic analyses of cryptic species within the Synbranchus marmoratus Bloch, 1795 (Synbranchiformes: Synbranchidae) grouping: species delimitations, karyotypic evolution and intraspecific diversification

A especie de peixe Synbranchus marmoratus tem sido reportada como um complexo de especies devido a elevada variabilidade cariotipica intraespecifica a despeito da dificuldade ou impossibilidade de distingui-las usando apenas caracteres morfologicos. O objetivo deste trabalho foi utilizar metodos citogeneticos e moleculares para determinar a delimitacao das especies e compreender a carioevolucao de S. marmoratus utilizando amostras coletadas em distintas localidades brasileiras. Dentre os especimes analisados, um alto grau de variacao citogenetica relativo aos numeros diploides e estrutura cariotipica foi observado, com cariotipos mostrando 2n=42, 44 e 46 cromossomos. Adicionalmente, utilizando sequencias de tres genes mitocondriais, as relacoes filogeneticas entre cada amostra com cariotipo conhecido foram determinadas, revelando uma divergencia nucleotidica significativa entre os cariomorfos. Alem disso, as analises indicam que rearranjos cromossomicos ocorreram independentemente nas distintas linhagens do complexo S. marmoratus, o que resultou no aparecimento de distintas variantes cariotipicas de forma nao linear em relacao aos numeros diploides e no surgimento de cromossomos similares e nao homologos. Finalmente, a integracao de uma abordagem citogenetica molecular e filogenetica permitiu a determinacao de cromossomos especificos que, possivelmente, estao envolvidos em rearranjos e um melhor entendimento sobre os processos evolutivos envolvidos na diferenciacao do genero Synbranchus.
On detection of the stochastic gravitational-wave background using the Parkes pulsar timing array

We search for the signature of an isotropic stochastic gravitational-wave background in pulsar timing observations using a frequency-domain correlation technique. These observations, which span roughly 12 yr, were obtained with the 64-m Parkes radio telescope augmented by public domain observations from the Arecibo Observatory. A wide range of signal processing issues unique to pulsar timing and not previously presented in the literature are discussed. These include the effects of quadratic removal, irregular sampling and variable errors which exacerbate the spectral leakage inherent in estimating the steep red spectrum of the gravitational-wave background. These observations are found to be consistent with the null hypothesis that no gravitational-wave background is present, with 76 per cent confidence. We show that the detection statistic is dominated by the contributions of only a few pulsars because of the inhomogeneity of this data set. The issues of detecting the signature of a gravitational-wave background with future observations are discussed.
Timages : Enhancing Time Graphs with Iconographic Information

Various time-based visualization techniques have been designed to support the temporal analysis of data collections. While quantities play a secondary role in traditional timelines that reserve space for each individual data item to be observed, time graphs rather display quantitative information and they provide interaction means to filter for a subset of the data. Timages is a hybrid approach that enhances quantitative time graphs with qualitative information in an infographic-style. By (1) scaling thumbnails of data items dependent on relevance to the observed topic and by (2) time-dependent positioning these thumbnails inside a temporally aligned area with a novel space-filling strategy, the most relevant items in the entire data collection as well as predominant data items of certain time ranges are instantly seizable without the need to interact with the time graph.
Genetics and conservation of rare and endemic plants: the case of "Genista sanabrensis" (Fabaceae) in the Iberian Peninsula

Genista sanabrensis Valdes Berm. , Castrov. & Casaseca (Fabaceae) is an endemic and rare species of the Northwestern Iberian Peninsula. Despite its limited distribution, the species is locally abundant and therefore not categorized by the IUCN criteria as threatened at the national level. However, comprehensive studies on the genetic diversity and structure of rare and endemic species from Iberian Peninsula are urgently needed to promote effective conservation and management activities. Therefore, we conducted amplified fragment length polymorphism (AFLP), nuclear rDNA (ITS, ETS) and plastid regions ( trnL, trnL-F , matK , rbcL ) analyses to characterize the genetic diversity and variation of this species within and between populations. Our results confirm the monophyly of the species compared to closely related taxa. The presence of insertions/deletions together with point mutations makes the northern populations indispensable in the elaboration of conservation strategies. Genetic diversity was moderate/low, although the survival of these populations at the genetic level shows no signs of being threatened. This study provides important insights into the genetic structure of G. sanabrensis with potential applications to its effective conservation.
Spatio-temporal analysis of meta-data semantics of market shares over large public geosocial media data

ABSTRACT Monitoring market share changes over space and time is an essential and continuous task for commercial companies and their third-party local agents to adjust their sale campaigns and marketing efforts for profit maximisation. This paper uses social media data as a cheap and up-to-date source to reveal the implicit semantics that are embedded in the meta-data of public geosocial datasets. We use Twitter data as a prime example of rich geosocial data. These data are associated with several meta-data attributes. Using this meta-data, we perform a geospatial analysis for the source platform from which a tweet is posted, e.g. from Apple or Android device. Our analysis studies all counties in US connected states over 2 years 2016–2017. We show that market structure at the national level masks substantial variation at the county scale. Moreover, we find strong spatial autocorrelation in platform distribution and market share in the US. In addition, we show interesting changes over the 2 years that motivates further analysis at different spatial and temporal levels. Our results are supported with visual maps of location quotients and market dominance, in addition to formal test results of spatial autocorrelation, and spatial Markov analysis.
