ABUNDANCES OF STARS WITH PLANETS: TRENDS WITH CONDENSATION TEMPERATURE,

Precise abundances of 18 elements have been derived for 10 stars known to host giant planets from high signal-to-noise ratio, high-resolution echelle spectroscopy. Internal uncertainties in the derived abundances are typically ≲ 0.05 dex. The stars in our sample have all been previously shown to have abundances that correlate with the condensation temperature (Tc) of the elements in the sense of increasing abundances with increasing Tc; these trends have been interpreted as evidence that the stars may have accreted H-depleted planetary material. Our newly derived abundances also correlate positively with Tc, although slopes of linear least-square fits to the [m/H]–Tc relations for all but two stars are smaller here than in previous studies. When considering the refractory elements (Tc >900 K) only, which may be more sensitive to planet formation processes, the sample can be separated into a group with positive slopes (four stars) and a group with flat or negative slopes (six stars). The four stars with positive slopes have very close-in giant planets (three at 0.05 AU) and slopes that fall above the general Galactic chemical evolution trend. We suggest that these stars have accreted refractory-rich planet material but not to the extent that would increase significantly the overall stellar metallicity. The flat or negative slopes of the remaining six stars are consistent with recent suggestions of a planet formation signature, although we show that the trends may be the result of Galactic chemical evolution.

This paper considers how trading volume impacts upon the first three moments of REIT returns. Consistent with previous studies of the broader stock market, we find that volume is a significant factor with respect to both returns and volatility. We also find evidence supportive of the Hong & Stein’s (2003) Investor Heterogeneity Theory with respect to the finding that skewness in REIT index returns is significantly related to volume. Furthermore, we also report findings that show the influence of the variability of volume with skewness.

A New Stall-Onset Criterion for Low Speed Dynamic-Stall

The Beddoes/Leishman dynamic-stall model has become one of the most popular for the provision of unsteady aerofoil data embedded in much larger codes. The underlying modeling philosophy was that it should be based on the best understanding, or description, of the associated physical phenomena. Even though the model was guided by the flow physics, it requires significant empirical inputs in the form of measured coefficients and constants. Beddoes provided these for a Mach number range of 0.3–0.8. This paper considers one such input for a Mach number of 0.12, where, from the Glasgow data, it is shown that the current stall-onset criterion, and subsequent adjustments, yield problematic results. A new stall criterion is proposed and developed in the best traditions of the model. It is shown to be very capable of reconstructing the Glasgow’s data for stall onset both the ramp-up and oscillatory tests.
Strongly Secure Certificateless Signature Scheme Supporting Batch Verification

We propose a strongly secure certificateless signature scheme supporting batch verification, which makes it possible for a verifier to verify a set of signatures more efficiently than verifying them one by one. In an identity-based digital signature scheme, private key generator (PKG) knows each user's signing key, so it can generate a signature which is indistinguishable from the signature generated by the user. This is a serious problem because the property of signature nonrepudiation will not be achieved. In our proposed scheme, it is impossible for PKG to produce a signature which is indistinguishable from any signature produced by a user. Compared with existing signature schemes with batch verification, although our proposed scheme is not the most efficient one, it achieves Girault's level-3 security, while the others have Girault's level-1 or level-2 security only. We also formally prove that the proposed scheme is unforgeable and satisfies Girault's level-3 security based on hard problems.
THE PSYHOMETRIC PROPERTIES OF MINDFULNESS IN PARENTING QUESTIONNAIRE (MIPQ) IN TURKISH SAMPLE

The aim of the study is to examine the psychometric properties of the Mindfulness in Parenting Questionnaire developed by McCaffrey, Reitman and Black (2017) in Turkish parents. At the beginning of the study, linguistic equivalence was examined. After observing that the scale is linguistically equivalent to the original form, the Confirmatory Factor Analysis (CFA) was applied for the construct validity. Confirmatory Factor Analysis was employed to calculate fit indices and the results showed that goodness of fit indices of the scale are within acceptable limits for two factor (χ2/sd=1.927, RMSEA=.049, GFI=.90, CFI=.90, IFI=.90) and for the one factor model (χ2/sd=1.904, RMSEA=.049, GFI=.90, CFI=.90, TLI=.90). The Cronbach’s alpha internal consistency coefficient was found to range between . 73 and . 87 for each subscale and the total scale. The results revealed that corrected item total correlations were between . 50 and . 85 and the t-test results for the upper 27% and lower 27% of scores were significant (p<.05). Also, it was found to significantly correlated with the Parent-Child Communication Scale and the Mindful Attention Awareness Scale. To conclude, Mindfulness in Parenting Questionnaire appears to be a valid and reliable measure for Turkish parents. Article visualizations:
A comparison of the line-interception, variable-plot and loop methods as used to measure shrub-crown cover.

Determining the percentage of ground covered by shrubby vegetation is an integral part of range inventory and of range condition and trend studies. Measurement of plant cover is used in making site descriptions and in studying brush control, seeding, and grazing management. A change in plant cover often reflects a change in management practices. No accurate method of measuring plant cover has been devised. In most instances only an estimation of plant cover is made. However, Smith (1944) showed that cover estimates vary significantly among individuals on different days and even on the same day. Many range technicians, land managers, and ecologists have recognized the need for a rapid, accurate, and easyto-use method of measuring plant cover. The loop procedure of the Parker 3-Step Method is used widely in condition and trend studies. A3/4-inch loop is utilized to obtain the plant density index, a frequency measurement. Recently, Johnston (1957) employed the loop procedure to
Fabrication of an antireflective polymer optical film with subwavelength structures using a roll-to-roll micro-replication process

An antireflective optical film with subwavelength structures replicated by use of a roll-to-roll micro-replication process (RMRP) is investigated. Firstly, a single layer of a nanostructure on a polymer film is designed for an antireflection purpose by the finite difference time domain method in the visible light spectrum. Structures of a conical cylinder array, with spatial period of 400 nm, diameter of 200 nm and height of 350 nm, are numerically obtained. Then, such structures are fabricated by RMRP combining originated structure fabrication realized by deep ultra-violet lithography and dry etching, Ni mold electroplating and replication by using the roll-to-roll process imprinting into the flexible polyethylene terephthalate substrate. A nanostructure roller mold bonded with Ni molds has been successfully fabricated and coated with the self-assembly monolayer process for the purpose of fabricating an anti-adhesion film and improving the lifetime of the Ni molds. The duplicated nanostructure films show a good optical quality of antireflection (AR ⩽ 2.45% in a 400–700 nm spectral range) and are in good agreement with the theoretical predictions. The experimental results show that the developed process is a promising and cost-effective method for the continuous duplication of flexible devices with nano-scaled feature sizes used in nanophotonics by RMRP.
A comparative cohort study of the effect of rainfall and temperature on diarrhoeal disease in faecal sludge and non-faecal sludge applying communities, Northern Ghana

This study assesses the effect of temperature and rainfall on diarrhoea incidence in sludge and non-faecal sludge applying farming communities in Northern Ghana. Diarrhoea episode data were obtained through an open cohort survey involving 1,341 and 1,323 individuals from the sludge and non-faecal sludge communities, respectively. The effects of temperature and rainfall variables on diarrhoea incidence were assessed using autoregressive Poisson regression models. Maximum rainfall events in the same bi-week increased the risk of diarrhoea in the sludge (relative risk, RR: 1.034; confidence interval, CI: 1.02–1.05) and non-sludge (RR: 1.003; CI: 0.99–1.01) communities. However, this was not significant in the non-sludge communities ( p > 0.05). Minimum rainfall occurring in the same bi-week decreased the risk of diarrhoea in both communities. Maximum temperature decreased the risk of diarrhoea in the sludge communities (RR: 0.50; CI: 0.38–0.65), but increased the risk in the non-sludge communities (RR: 1.19 CI: 1.02–1.40). Minimum temperature increased diarrhoea disease risk (RR: 3.50; CI: 2.10–5.80) in the sludge communities, but decreased the risk (RR: 0.70; CI: 0.54–0.84) in the non-sludge communities. The study stresses the need to account for weather variables when developing schemes for the land application of faecal sludge.
Business models: A challenging agenda

Most research on business models lies in the literature on strategy and competitive advantage and focuses on their role as descriptors of actual phenomenon, often by reference to taxonomic categories. In this article, we explore how business models can be seen as a set of cognitive configurations that can be manipulable in the minds of managers (and academics). By proposing a typology of business models that emphasizes the connecting of traditional value chain descriptors with how customers are identified and satisfied, and how the firm monetizes its value, we explore how business model configurations can extend current work on cognitive categorization and open up new possibilities for organization research.
The role of gender in team collaboration and performance

Abstract Given that women continue to be underrepresented in STEM (Science, Technology, Engineering and Math) and that scientific innovations are increasingly produced by team collaborations, we reviewed the existing literature regarding the effects of gender diversity on team processes and performance. Recent evidence strongly suggests that team collaboration is greatly improved by the presence of women in the group, and this effect is primarily explained by benefits to group processes. The evidence concerning the effect of gender diversity on team performance is more equivocal and contingent upon a variety of contextual factors. In light of the importance of collaboration in science, promoting the role of women in the field can have positive practical consequences for science and technology.
Assessment of an atmospheric transport model for annual inverse estimates of California greenhouse gas emissions

Atmospheric inverse estimates of gas emissions depend on transport model predictions, hence driving a need to assess uncertainties in the transport model. In this study we assess the uncertainty in WRF‐STILT (Weather Research and Forecasting and Stochastic Time‐Inverted Lagrangian Transport) model predictions using a combination of meteorological and carbon monoxide (CO) measurements. WRF configurations were selected to minimize meteorological biases using meteorological measurements of winds and boundary layer depths from surface stations and radar wind profiler sites across California. We compare model predictions with CO measurements from four tower sites in California from June 2013 through May 2014 to assess the seasonal biases and random errors in predicted CO mixing ratios. In general, the seasonal mean biases in boundary layer wind speed (< ~ 0.5 m/s), direction (< ~ 15°), and boundary layer height (< ~ 200 m) were small. However, random errors were large (~1.5–3.0 m/s for wind speed, ~ 40–60° for wind direction, and ~ 300–500 m for boundary layer height). Regression analysis of predicted and measured CO yielded near‐unity slopes (i.e., within 1.0 ± 0.20) for the majority of sites and seasons, though a subset of sites and seasons exhibit larger (~30%) uncertainty, particularly when weak winds combined with complex terrain in the South Central Valley of California. Looking across sites and seasons, these results suggest that WRF‐STILT simulations are sufficient to estimate emissions of CO to up to 15% on annual time scales across California.
Fiscal policy and economic growth: empirical evidence from EU countries

This paper studies whether a reallocation of the components of public spending and revenues can enhance economic growth using data on 14 EU countries during 1990-2006. The results provide support for endogenous growth models. Specifically, the findings are: a) public expenditures on infrastructure (economic affairs, general public services) and property rights protection (defense, public order-safety) exert a positive impact on growth; b) distortionary taxation depresses growth; c) government expenditures on human capital enhancing activities (education, health, housing-community amenities, environment protection, recreation-culture-religion) and social protection do not have a significant growth effect. However, when coefficient heterogeneity across countries along with non-linearities are taken into account and public expenditures are further disaggregated, we have in addition that government outlays on education, defense and social protection are growth-enhancing. These findings are robust to changes in specification and estimation methodology.
South-north asymmetry of field-aligned currents in the magnetotail observed by Cluster

mechanism of the north‐south asymmetry, we mapped the FACs along the field line into the polar region. The footprints of the FACs also show a difference between the Southern and Northern hemispheres (as a function of mapped latitude). These characteristics suggest a north‐south asymmetry of the FACs in the magnetosphere. Further investigation is needed to identify the causes of this asymmetry, although the configuration of the magnetosphere, the polar cap boundary, the conductivity in the ionosphere, or the various solar wind‐magnetosphere interaction processes all may be contributors. That the FAC densities are different between the hemispheres suggests that an important source of these currents must be a voltage generator.
tmRNA entry into stalled ribosomes The role of SmpB and the ribosomal decoding center in licensing

In bacteria, stalled ribosomes are recycled by a hybrid transfer–messenger RNA (tmRNA). Like tRNA, tmRNA is aminoacylated with alanine and is delivered to the ribosome by EF-Tu, where it reacts with the growing polypeptide chain. tmRNA entry into stalled ribosomes poses a challenge to our understanding of ribosome function because it occurs in the absence of a codon– anticodon interaction. Instead, tmRNA entry is licensed by the binding of its protein partner, SmpB, to the ribosomal decoding center. We analyzed a series of SmpB mutants and found that its C-terminal tail is essential for tmRNA accommodation but not for EF-Tu activation. We obtained evidence that the tail likely functions as a helix on the ribosome to promote accommodation and identified key residues in the tail essential for this step. In addition, our mutational analysis points to a role for the conserved K131GKK tail residues in trans-translation after peptidyl transfer to tmRNA, presumably EF-G-mediated translocation or translation of the tmRNA template. Surprisingly, analysis of A1492, A1493, and G530 mutants reveals that while these ribosomal nucleotides are essential for normal tRNA selection, they play little to no role in peptidyl transfer to tmRNA. These studies clarify how SmpB interacts with the ribosomal decoding center to license tmRNA entry into stalled ribosomes.
Optimal environmental range for Juncus effusus, an important plant species in an endangered insect species ( Nannopya pygmaea )habitat in Korea

Juncus effusus is mostly found in freshwater wetlands and is widely used for landscaping and creating artificial wetlands due to its high ecological value. J. effusus tends to dominate during the early stage (3-10 years) of the second succession in abandoned paddy fields. This study focused on the environmental characteristics of J. effusus to create habitat for an endangered species, Nannopya pygmaea, which lives in wetlands dominated by J. effusus. Considering the distribution of J. effusus and N. pygmaea, 63 quadrats at eight wetlands were investigated between May and June 2006 during the critically dry period. Fifty-three species from 28 families co-occurred with J. effusus, and Persicaria thunbergii was the most abundant (63.5%). The optimal ranges of distribution (ORD) for the water variables were water depth, -2 to 10 cm; dissolved oxygen, 0.99-3.55 mg/kg, conductivity (CON), 23.40-115.40 µs/cm, total dissolved solid, 12.53-57.60 mg/L; pH, 5.00-6.87; K + , 0.11-1.46 mg/L; Ca 2+ , 1.53-5.85 mg/L; Na + , 3.16-7.47 mg/L; Mg 2+ , 0.11-1.96 mg/L; NO 3 -N, < 0.001-0.072 mg/L; NH 4 -N, 0.005-0.097 mg/L; and PO 4 -P, 0.006-0.047 mg/L. ORDs for the soil variables were water content, 1.052. 96%; loss-on ignition method (LOI), 5.07-7.81%; CON, 23.70-59.70 µs/cm; pH, 4.40-5.16; extracted (e) K +
Electronic Government and the Rural Poor: The Case of Gyandoot

In the poor and drought-prone rural district of Dhar in Madhya Pradesh, India, Gyandoot has tried to make government services more accessible to villagers through information and communications technology (ICT) since January 2000. Two recent surveys of this e-government project allow us to evaluate whether the local population is benefiting. Main findings are that service satisfaction is quite high, but usage is low, and Gyandoot is not reaching the poorest people. We conclude that much of the potential benefits of e-government are not being realized. Lessons for ICT projects that intend to benefit the rural poor include the use of appropriate technology, implementation of the project by agents who have incentives to serve the poor, community participation and ownership, availability of pro-poor services, and campaigns to raise awareness.
Effect of processing on the nutritional qualities of three fish species ( Synodontis clarias , Trachurus trecae and Clarias gariepinus )

The effects of different processing methods (oven drying, solar drying, smoking and boiling) on the proximate composition and organoleptic properties of three fish species (Clarias gariepinus, Trachurus trecae and Synodontis clarias) were investigated. The objective of this work is to know the best processing methods, the effect of processing on organoleptic characteristics and nutritional values of fish products. The result of the proximate composition of the fish species showed that the highest protein content (61.21%) was in C. gariepinus processed with solar dryer. The result of moisture content indicated that solar dried products were consistently lower in all the fish products, the least (14.21%) was in the S. clarias while all the boiled fish products had the highest moisture percentage, as would be expected was high in all the boiled fish products. Protein was higher in the fish products processed with solar. The lipid was reduced to the least value of 1.12% in the S. clarias processed with solar dried. In drying, the important factors for consideration are moisture, lipids and protein, though low moisture would ensure fish product with extended shelf life or can keep for a couple of weeks. To have a longer shelf life, high protein is desirable, low lipid is equally desirable as to reduce oxidation and rancidity in the fish products which causes offflavor and bad taste in fish products. The overall performance showed that for flavour, the highest value recorded was 2.9 in solar dried S. clarias. In conclusion, all the other processing methods are good and could extend the shelf life of the products with an exception of boiling method; they could keep the fish product free from spoilage and microorganisms attack for some period. Solar drying was adjudged to be one of the attractive means of processing fish products. The organoleptic properties of the fish species were determined using questionnaires. This study clearly indicated that the proximate values obtained could be of help in choosing fish based on nutritional values.
Average packing ratio as a parameter for analyzing the karyotypes of dioecious cucurbits

Abstract Chromosome studies and in situ estimation of 4C nuclear DNA content were carried out on dioecious Coccinia indica and Trichosanthes dioica to understand the differential condensation of mitotic chromosome in relation to sex. The somatic chromosome number for each sex form of C. indica and T. dioica was found to be 2n = 24 and 22 respectively. The karyotypes of the sex forms of both species show high homogeneity, though a distinct hetermorphic pair of sex chromosomes is found in male plants of C. indica. Interrelationship between the 4C nuclear content and the chromosome length has been explained in terms of average packing ratio. The data suggests that average packing ratio is a determinant of distinction between two sexes and therefore could be used as a parameter for analyzing the karyotypes of dioecious plants.
Effects of selenium supplementation on serum cortisol in repeatedly handled cattle

This study evaluated the relationship between Se supplementation and serum cortisol in repeatedly handled cattle. Sixty Nellore calves were randomly distributed into four experimental groups, which were fed a mineral-protein mixture added with Se to achieve individual daily supplementation of 0 (Gc), 3.6 (G 3.6 ), 5.4 (G 5.4 ) and 6.4 (G 6.4 ) mg Se. Stressful handling procedures and blood sampling were performed on days 0, 15, 30, 60, 90 and 120. Serum cortisol increased until day 90 and decreased on day 120, irrespective of Se supplementation. This finding shows that cattle reached a stress state but adapted. Cortisol and Se levels were not markedly correlated. Serum Se increased over the course of the experiment in the supplemented groups. However, because serum Se decreased in Gc, it may have mobilized to form the selenoproteins needed to remove metabolic wastes from handling-related oxidative stress.
