The Effects of the Organizational Psychological Capital on the attitudes of Commitment and Satisfaction: A Public Sample in Turkey

Organizational psychological capital is employee’s psychological states beyond intellectual capital in obtaining and sustaining the competitive advantage. The purpose of this study was to explore the effects of hope, resilience, optimism and self efficacy sub dimensions of the psychological capital on the attitudes of organizational commitment and job satisfaction. The survey method was used with using a questionnaire including Organizational Psychological Capital Scale, Organizational Commitment Scale and Job Satisfaction Scale with demographic information. Data were collected from 213 employees working different units in ministries and connected institutions in Ankara. Confirmative factor analysis and structural equating modeling were employed with using Amos v.16. 0. The results showed that organizational commitment has positive relationship between hope and optimism dimensions and job satisfaction has positive relationship between resilience, hope and optimism dimensions of the organizational psychological capital. Ultimately organizational psychological capital was found a significant predictor of the employee attitudes of organizational commitment and job satisfaction.
Exergames for women with fibromyalgia: a randomised controlled trial to evaluate the effects on mobility skills, balance and fear of falling

Background Exergames are a new form of rehabilitation that combine the characteristics of physical exercise and the benefits of non-immersive virtual reality (VR). Effects of this novel therapy in women fibromyalgia are still unknown. The objective was to evaluate the effects of exergame-based intervention on mobility skills, balance and fear of falling in women with fibromyalgia. Methods This study was a randomized controlled trial with concealed allocation. Seventy-six women with fibromyalgia were divided into two groups: the exercise group received an eight week intervention based on exergames, while the control group continued their usual activities. Mobility skills were evaluated using the timed up and go test, while balance was assessed using the functional reach test, and the CTSIB protocol. Fear of falling was evaluated on a scale of 0–100 (0, no fear; 100, extreme fear). Measurements were performed before and after the intervention. A repeated-measures linear mixed model was used to compare the effects of the intervention between the two groups. Results The exercise group was significantly quicker than the control group in the timed up and go test (MD, −0.71; 95% CI [−1.09–0.32]; p < 0.001). There were also significant improvements in functional reach and a reduced fear of falling (MD, 4.34; 95% CI [1.39–7.30]; p = 0.005 and MD, −9.85; 95% CI [−0.19–−0.08]; p = 0.048, respectively). Discussion The improved TUG observed herein was better than the smallest real difference. Based on the results on mobility skills, balance and fear of falling, exergames may be an effective tool as a therapy for women with fibromyalgia.
Toeplitz Quantization and Asymptotic Expansions for Real Bounded Symmetric Domains 1. Covariant Calculi on Complex and Real Symmetric Domains

An analogue of the star product, familiar from deformation quan-tization, is studied in the setting of real bounded symmetric domains. The analogue turns out to be a certain invariant operator, which one might call star restriction, from functions on the complexification of the domain into functions on the domain itself. In particular, we establish the usual (i.e. semiclassical) asymptotic expansion of this star restriction, and further obtain a real-variable analogue of a theorem of Arazy and Ørsted concerning the analogous expansion for the Berezin transform. Let D = G/K be an irreducible bounded symmetric domain in C d in the Harish-Chandra realization, with G the identity connected component of the group of all biholomorphic self-maps of D and K the stabilizer of the origin; K can also be realized as the automorphism group Aut(Z) of the Hermitian Jordan triple Z ≈ C d associated with D. For ν > p − 1, p being the genus of D, let H 2 ν (D) denote the standard weighted Bergman space on D, i.e. the subspace of all holomorphic functions in L 2 (D, dµ ν), with (1) dµ ν (z) = c ν K(z, z) 1−ν/p dz, where dz stands for the Lebesgue measure, K(z, w) is the ordinary (unweighted) Bergman kernel of D, and c ν is a normalizing constant to make dµ ν a probability measure. The space H 2 ν (D) carries the unitary representation U (ν) of G given by (2) U (ν) g f (z) = f (g −1 (z)) · J g −1 (z) ν/p , g ∈ G, f ∈ H 2 ν (D), where J g denotes the complex Jacobian of the mapping g. (In general, if ν/p is not an integer, then U (ν) is only a projective representation due to the ambiguity in the choice of the power J g −1 (z) ν/p . ) This situation will henceforth be called the complex bounded case. In addition to bounded symmetric domains, we will also consider the complex flat case of a Hermitian vector space D = Z ≈ C d , with D = G/K for G the group of all orientation-preserving rigid motions of Z, and K = U (Z) ≈ U d (C) the stabilizer of the origin in G; the spaces H 2 ν (Z) will then be the Segal-Bargmann spaces of all entire functions which are square-integrable with …
Fast 100-nm resolution three-dimensional microscope reveals structural plasticity of mitochondria in live yeast

By introducing beam-scanning multifocal multiphoton 4Pi-confocal microscopy, we have attained fast fluorescence imaging of live cells with axial super resolution. Rapid scanning of up to 64 pairs of interfering high-angle fields and subsequent confocal detection enabled us to perform three to five times finer optical sectioning than confocal microscopy. In conjunction with nonlinear image restoration, we demonstrate, to our knowledge for the first time, three-dimensional imaging of live eukaryotic cells at an equilateral resolution of ≈100 nm. This imaging mode allowed us to reveal the morphology and size of the green fluorescent protein-labeled mitochondrial compartment of live Saccharomyces cerevisiae (bakers' yeast) growing on different carbon sources. Our studies show that mitochondria of cells grown on medium containing glycerol as the only carbon source, as opposed to glucose-grown cells, exhibit a strongly branched tubular reticulum. We determine the average tubular diameter and find that it increases from 339 ± 5 nm to 360 ± 4 nm when changing from glucose to glycerol, that is, from a fermentable to a nonfermentable carbon source. Moreover, this change is associated with a 2.8-fold increase of the surface of the reticulum, resulting in an average increase in volume of the mitochondrial compartment by a factor of 3.0 ± 0.2.
On the Rate of Convergence and Error Bounds for LSTD(\(\lambda\))

We consider LSTD($\lambda$), the least-squares temporal-difference algorithm with eligibility traces algorithm proposed by Boyan (2002). It computes a linear approximation of the value function of a fixed policy in a large Markov Decision Process. Under a $\beta$-mixing assumption, we derive, for any value of $\lambda \in (0,1)$, a high-probability estimate of the rate of convergence of this algorithm to its limit. We deduce a high-probability bound on the error of this algorithm, that extends (and slightly improves) that derived by Lazaric et al. (2012) in the specific case where $\lambda=0$. In particular, our analysis sheds some light on the choice of $\lambda$ with respect to the quality of the chosen linear space and the number of samples, that complies with simulations.
Gendered Biographies: The Czech State-Socialist Gender Order in Oral History Interviews

A large collection of autobiographical life story material available in oral-history data is used to examine how women and men of different socio-political groups (workers, intelligentsia, dissidents, and communist functionaries) narrate their lives in the time of state-socialist Czechoslovakia. Of particular interest is what these narratives imply for an understanding of the state-socialist gender order. The analysis combines quantitative (the frequency of word co-occurrences) and qualitative (a hermeneutic reading of text fragments) approaches. The results provide evidence that empirically supports what has previously been suggested in the literature: there was an interdependence of private and public spheres, with the family sphere differing in importance for women and men. Additionally, the discursive density and arrangement of these spheres in the life stories differs according to sociopolitical groups, and a third sphere, which we have labelled ‘politics’, emerges for some groups. The findings reveal insights into the relationship between the gender order and the life course through a narrative articulation of life stories of different social groups in Czech state-socialist society.
Intraindividual Comparison of Color Perception and Contrast Sensitivity with and without a Blue Light-Filtering Intraocular Lens

Purpose To investigate color perception and contrast sensitivity with and without additional glare in pseudophakic patients with a conventional intraocular lens (IOL) in one eye and a blue light-filtering IOL in the fellow eye. Methods Twenty-three bilaterally pseudophakic patients with a conventional IOL (Acr ySof SA60AT) and a blue light-filtering IOL (AcrySof Natural SN60AT) were tested for intraindividual comparison of visual acuity (ETDRS chart), color perception (Farnsworth-Munsell 100-Hue test), and contrast sensitivity with and without glare (Contrast Sensitivity Pattern Generator). Information about subjective perception was gathered through a questionnaire. Results Four patients (17.4%) observed some difference in monocular color perception. Color testing did not show significantly different results for the two IOL types expressed as total error score and segmental error subscores for protan, deutan, and tritan ranges. Regarding contrast sensitivity, 5 patients (21.7%) indicated noticeable difference between the two eyes. Contrast sensitivity testing, however, showed similar curves for the two IOL types with and without additional glare. Conclusions Despite some subjective difference in color and contrast perception in a minority of patients, the study did not show significantly different results for the two IOL types.
Generation of BAC Transgenic Tadpoles Enabling Live Imaging of Motoneurons by Using the Urotensin II-Related Peptide (ust2b) Gene as a Driver

Xenopus is an excellent tetrapod model for studying normal and pathological motoneuron ontogeny due to its developmental morpho-physiological advantages. In mammals, the urotensin II-related peptide (UTS2B) gene is primarily expressed in motoneurons of the brainstem and the spinal cord. Here, we show that this expression pattern was conserved in Xenopus and established during the early embryonic development, starting at the early tailbud stage. In late tadpole stage, uts2b mRNA was detected both in the hindbrain and in the spinal cord. Spinal uts2b+ cells were identified as axial motoneurons. In adult, however, the uts2b expression was only detected in the hindbrain. We assessed the ability of the uts2b promoter to drive the expression of a fluorescent reporter in motoneurons by recombineering a green fluorescent protein (GFP) into a bacterial artificial chromosome (BAC) clone containing the entire X. tropicalis uts2b locus. After injection of this construction in one-cell stage embryos, a transient GFP expression was observed in the spinal cord of about a quarter of the resulting animals from the early tailbud stage and up to juveniles. The GFP expression pattern was globally consistent with that of the endogenous uts2b in the spinal cord but no fluorescence was observed in the brainstem. A combination of histological and electrophysiological approaches was employed to further characterize the GFP+ cells in the larvae. More than 98% of the GFP+ cells expressed choline acetyltransferase, while their projections were co-localized with α-bungarotoxin labeling. When tail myotomes were injected with rhodamine dextran amine crystals, numerous double-stained GFP+ cells were observed. In addition, intracellular electrophysiological recordings of GFP+ neurons revealed locomotion-related rhythmic discharge patterns during fictive swimming. Taken together our results provide evidence that uts2b is an appropriate driver to express reporter genes in larval motoneurons of the Xenopus spinal cord.
Neuroprotection of Grape Seed Extract and Pyridoxine against Triton-Induced Neurotoxicity

Triton WR-1339 administration causes neurotoxicity. Natural products and herbal extracts can attenuate cerebral injury. In the present study, we investigated the neuroprotective role of grape seed extract and/or vitamin B6 against triton-induced neurotoxicity. Thirty-five adult male albino rats of the Sprague-Dawley strain, weighing 140–145 g, were divided into five groups: control, triton, grape seed extract + triton, grape seed extract + triton + vitamin B6, and vitamin B6 + triton. The hematological and biochemical analyses were carried out. Alteration in iNOS mRNA gene expression was determined using reverse-transcriptase PCR analysis. In addition, qualitative DNA fragmentation was examined using agarose gel electrophoresis. Triton-treatment caused significant disturbances in the hematological parameters, the neurological functions, and the antioxidant profile. Also, triton significantly increased the iNOS mRNA expression and DNA damage. Our results showed that grape seed extract and/or vitamin B6 could attenuate all the examined parameters. These natural substances could exhibit protective effects against triton-induced neurological damage because of their antioxidative and antiapoptotic capacities.
Myelin Galactolipids Are Essential for Proper Node of Ranvier Formation in the CNS

The vertebrate myelin sheath is greatly enriched in the galactolipids galactocerebroside (GalC) and sulfatide. Mice with a disruption in the gene that encodes the biosynthetic enzyme UDP-galactose:ceramide galactosyl transferase (CGT) are incapable of synthesizing these lipids yet form myelin sheaths that exhibit major and minor dense lines with spacing comparable to controls. These CGT mutant mice exhibit a severe tremor that is accompanied by hindlimb paralysis. Furthermore, electrophysiological studies reveal nerve conduction deficits in the spinal cord of these mutants. Here, using electron microscopic techniques, we demonstrate ultrastructural myelin abnormalities in the CNS that are consistent with the electrophysiological deficits. These abnormalities include altered nodal lengths, an abundance of heminodes, an absence of transverse bands, and the presence of reversed lateral loops. In contrast to the CNS, no ultrastructural abnormalities and only modest electrophysiological deficits were observed in the peripheral nervous system. Taken together, the data presented here indicate that GalC and sulfatide are essential in proper CNS node and paranode formation and that these lipids are important in ensuring proper axo-oligodendrocyte interactions.
Introns excised from the Delta primary transcript are localized near sites of Delta transcription

Introns excised from the primary transcript of Delta (Dl), a Drosophila neurogenic gene, accumulate to unusually high levels in embryos. High resolution in situ hybridization reveals a striking localization of the excised introns to two foci per embryonic nucleus. The number of foci can be altered by varying the number of Dl genes present in the embryonic nucleus, suggesting that the excised introns are localized near sites of Dl transcription. This conclusion is supported by the observation that larval and imaginal disc nuclei containing two copies of Dl exhibit only one focus of intron accumulation, as expected for nuclei in which homologous chromosomes are paired. Interestingly, the excised introns do not appear to diffuse away from the foci until late prophase, at which time the foci disperse into numerous small dots of hybridization. These results suggest that the excised Dl introns may be associated with a structural element within the nucleus that is dissociated during cell division.
Lower Serum Magnesium Is Associated with Cardiovascular Risk Factors and Mortality in Haemodialysis Patients

Background: Hypomagnesaemia is a cardiovascular (CV) risk factor in the general population. The aim of this study was to evaluate the relationship between pre-dialysis magnesium (Mg) and CV risk markers, [including pulse pressure (PP), left ventricular mass index (LVMI) and vascular calcifications (VC)], and mortality in haemodialysis (HD) patients. Methods: We performed a 48-month prospective study in 206 patients under pre-dilution haemodiafiltration with a dialysate Mg concentration of 1 mmol/l. Results: Lower Mg concentrations were predictors of an increased PP (≥65 mm Hg) (p = 0.002) and LVMI (≥140 g/m2) (p = 0.03) and of a higher VC score (≥3) (p = 0.01). Patients with Mg <1.15 mmol/l had a lower survival at the end of the study (p = 0.01). Serum Mg <1.15 mmol/l was an independent predictor of all-cause (p = 0.01) and CV mortality (p = 0.02) when adjusted for multiple CV risk factors. Conclusions: Lower Mg levels seem to be associated with increased CV risk markers, like PP, LVMI and VC, and with higher mortality in HD patients.
Distributed queues in shared memory: multicore performance and scalability through quantitative relaxation

A prominent remedy to multicore scalability issues in concurrent data structure implementations is to relax the sequential specification of the data structure. We present distributed queues (DQ), a new family of relaxed concurrent queue implementations. DQs implement relaxed queues with linearizable emptiness check and either configurable or bounded out-of-order behavior or pool behavior. Our experiments show that DQs outperform and outscale in micro- and macrobenchmarks all strict and relaxed queue as well as pool implementations that we considered.
A Bayesian Estimation Framework for Pharmacogenomics Driven Warfarin Dosing: A Comparative Study

The incorporation of pharmacogenomics information into the drug dosing estimation formulations has been shown to increase the accuracy in drug dosing and decrease the frequency of adverse drug effects in many studies in the literature. In this paper, an estimation framework based on the Bayesian structural equation modeling, which is driven by pharmacogenomics, is proposed. The results show that the model compares favorably with the linear models in terms of prediction and explaining the variations in warfarin dosing.
Solar transition region above sunspots

Aims. We study the transition region (TR) properties above sunspots and the surrounding plage regions, by analyzing several sunspot reference spectra obtained by the SUMER (Solar Ultraviolet Measurements of Emitted Radiation) instrument in March 1999 and November 2006. Methods. We compare the SUMER spectra observed in the umbra, penumbra, plage, and sunspot plume regions. The hydrogen Lyman line profiles averaged in each of the four regions are presented. For the sunspot observed in 2006, the electron densities, differential emission measure (DEM), and filling factors of the TR plasma in the four regions are also investigated. Results. The self-reversals of the hydrogen Lyman line profiles are almost absent in sunspots at different locations (at heliocentric angles of up to 49°) on the solar disk. In the sunspot plume, the Lyman lines are also not reversed, whilst the lower Lyman line profiles observed in the plage region are obviously reversed, a phenomenon found also in the normal quiet Sun. The TR densities of the umbra and plume are similar and one order of magnitude lower than those of the plage and penumbra. The DEM curve of the sunspot plume exhibits a peak centered at log( T / K) ~ 5.45, which exceeds the DEM of other regions by one to two orders of magnitude at these temperatures. We also find that more than 100 lines, which are very weak or not observed anywhere else on the Sun, are well observed by SUMER in the sunspot, especially in the sunspot plume. Conclusions. We suggest that the TR above sunspots is higher and probably more extended, and that the opacity of the hydrogen lines is much lower above sunspots, compared to the TR above plage regions. Our result indicates that the enhanced TR emission of the sunspot plume is probably caused by a large filling factor. The strongly enhanced emission at TR temperatures and the reduced continuum ensure that many normally weak TR lines are clearly distinctive in the spectra of sunspot plumes.
Haemato-biochemical studies of Camels infested with Trypanosomiasis

Aim: To know the Haemato-Biochemical values of camels infested with Trypanosomiasis. Materials and Methods: A herd of 13 camels showing signs of inappetance, lethargy, going down in condition, urticarial swellings, oedema of pads and occasional shivering were examined. Blood samples were collected to screen for the trypanosomes and to record hemato-biochemical alterations. Treatment of both group I and group II was undertaken. Results: Nine camels were positive for Trypanosomes recording an incidence of 69.23%. A significant (P<0.01) increase in temperature and decrease in TEC was observed, while a significant (P<0.05) increase in TLC, neutrophils and eosinophils and significant (P<0.05) decrease in lymphocytes was noted in positive blood samples. Significant (P<0.05) decrease in blood glucose levels was recorded and one camel died due to hypoglycemic encephalopathy. Trypanosomiasis was treated successfully with Quinapyramine salts.
A sequent calculus for the Tamari order

We introduce a sequent calculus with a simple restriction of Lambek's product rules that precisely captures the classical Tamari order, i.e., the partial order on fully-bracketed words (equivalently, binary trees) induced by a semi-associative law (equivalently, tree rotation). We establish a focusing property for this sequent calculus (a strengthening of cut-elimination), which yields the following coherence theorem: every valid entailment in the Tamari order has exactly one focused derivation. One combinatorial application of this coherence theorem is a new proof of the Tutte-Chapoton formula for the number of intervals in the Tamari lattice $Y_n$. We also apply the sequent calculus and the coherence theorem to build a surprising bijection between intervals of the Tamari order and a certain fragment of lambda calculus, consisting of the $\beta$-normal planar lambda terms with no closed proper subterms.
Assessing nutrient limitation of Prochlorococcus in the North Pacific subtropical gyre by using an RNA capture method

It has been hypothesized that the planktonic community of the North Pacific subtropical gyre (NPSG) underwent a "domain shift" in the early 1980s in which phytoplankton of the domain Eukarya were supplanted by phytoplankton of the domain Bacteria, primarily Prochlorococcus. P limitation of eukaryotic phytoplankton was implicated as the causative chemical factor in the domain shift, and we sought to investigate the current nutrient limitation status of Prochlorococcus, now 2 decades since this event. We measured ribonucleic acid (RNA) synthesis rates by NPSG plankton at Station ALOHA in 33PO43‐ tracer incubations and found that RNA synthesis was the single largest biochemical sink for dissolved P, accounting for about half of the total PO43‐ uptake. We also found that NH4+ stimulated RNA synthesis but that PO43‐ did not, which suggested N limitation of plankton growth. We developed a new RNA capture procedure, termed radioisotope‐based tracking of RNA synthesis by hybridization and capture (RIBOTRACE), to measure RNA synthesis rates by Prochlorococcus exclusively. Data from this procedure showed that NH4+ stimulated RNA synthesis by Prochlorococcus and confirmed that Prochlorococcus was N limited and not P limited. Our RIBOTRACE data do not necessarily refute the domain shift hypothesis, but suggest that any critical period of P limitation required for the domain shift must have subsided and given way to the N‐limiting conditions that existed previously.
