Numerical Investigation of Spectral Evolution of Wind Waves. Part I: Wind-Input Source Function

Abstract This paper is dedicated to the investigation and calibration of the parameterized form for the wind-input source term Sin proposed earlier on the basis of field observations at Lake George, Australia. The main objective of this study was to obtain spectral forms for the wind-input source function Sin, which incorporates the novel observation-based features and at the same time satisfies the important physical constraint that the total integrated wind input must agree with independently observed magnitudes of the wind stress. Within this approach, a new methodology, a dynamic self-adjusting routine, was developed for correction of the wind-input source function Sin. This correction involves a frequency-dependent adjustment to the growth rate γ( f ), based on extrapolations from field data. The model results also show that light winds require higher-rate adjustments of the wind input than strong winds.
The Computation of Flow and Heat Transfer through an Orthogonally Rotating Square-Ended U-Bend Using Low-Reynolds-Number Models

We present computations of heat and fluid flow through a square-ended U-bend that rotates about an axis normal to both the main flow direction and also the axis of curvature. Two-layer and low-Reynolds-number mathematical models of turbulence are used at effective-viscosity (EVM) level and also at second-moment-closure (DSM) level. Moreover, two length-scale correction terms to the dissipation rate of turbulence are used with the low-Re models, the original Yap term, and a differential form that does not require the wall distance (NYap). The resulting predictions are compared with available flow and heat transfer measurements of water. While the main flow features are well reproduced by all models, the development of the mean flow within and just after the bend is better reproduced by the low-Re models. Turbulence levels within the rotating U-bend are underpredicted, but DSM models produce a more realistic distribution. Along the leading side, all models overpredict heat transfer levels just after the bend. Along the trailing side, the heat transfer predictions of the low-Re DSM with the NYap, are close to the measurements.
Stability of the Regular Hayward Thin-Shell Wormholes

The aim of this paper is to construct regular Hayward thin-shell wormholes and analyze their stability. We adopt Israel formalism to calculate surface stresses of the shell and check the null and weak energy conditions for the constructed wormholes. It is found that the stress-energy tensor components violate the null and weak energy conditions leading to the presence of exotic matter at the throat. We analyze the attractive and repulsive characteristics of wormholes corresponding to and , respectively. We also explore stability conditions for the existence of traversable thin-shell wormholes with arbitrarily small amount of fluid describing cosmic expansion. We find that the space-time has nonphysical regions which give rise to event horizon for and the wormhole becomes nontraversable producing a black hole. The nonphysical region in the wormhole configuration decreases gradually and vanishes for the Hayward parameter . It is concluded that the Hayward and Van der Waals quintessence parameters increase the stability of thin-shell wormholes.
Effect of water stress on growth components of winter safflower (Carthamus tinctorius L.).

A field study was carried out in order to determine the effect of irrigation, water stress imposed at different development stages on seed yield, seasonal evapotranspiration (ET), crop-water relationships, oil yield and plant growth components of safflower (Carthamus tinctorius L.) for winter sowing at Thrace Region in Turkey. The field trials were conducted on a loam Entisol soil, using cv. Dincer, the most popular variety in the region. A randomised complete block design with three replications was used. Three known growth stages of the plant were considered and a total of 8 (including rain fed) irrigation treatments were applied. Results of this study show that safflower is significantly affected by water shortage in the soil profile due to omitted irrigation during the sensitive vegetative stage. Highest yields were observed in the fully irrigated control. An evapotranspiration of 728 mm were calculated for non-stressed production for winter sowing. Safflower seed yield of this treatment was 4.05 ton per hectare.
Proposed Ethical Work Behavior Model in Boundaries of Organizational Domain

The organizational code of ethic plays a big role as linkage between the organization’s mission, values and principles with the standards of professional conduct. Due to this, the objective of this research is to identify the ethical work behavior and depict a baseline to predict the organizational code of ethic.Both inductive and deductive method of inquiry was adopted, starting with qualitative grounded theory as antecedent variables were bushed in linguistic form. The developed conceptual model, which was demonstrated by 28 items, measuring 6 constructs which tested the behavioral side of the ethical practices, in quantitative phase. The proposed “Ethical work behavior model” was studied for generalizability by smart-PLS and test for [a] the loadings of studied items on their anticipated latent variables and also test [b] the proposed relationship among a set of dependent and independent constructs. Result of 168 distributed questioners in 30 different academic base organizations, indicates that both situational and individual leverage can explain and predict the ethical work behavior.
Empirical Comparison of Alternative Implied Volatility Measures of the Forecasting Performance of Future Volatility

Implied volatility from the Black and Scholes (Journal of Political Economy 81, 1973, p. 637) model has been empirically analyzed for the forecasting performance of future volatility and is well known to be biased. Based on the belief that implied volatility from option prices can best estimate future volatility, this study identifies the best way to derive implied volatility to overcome the forecast bias associated with the Black‐Scholes model. For this, the following three models are considered: Heston’s model, which best addresses the problems associated with the Black‐Scholes model for pricing and hedging options; Britten-Jones and Neuberger’s model-free implied volatility (MFIV), which eliminates the model-oriented bias; and VKOSPI, the Korean version of the Chicago Board Options Exchange Market Volatility Index. This study conducts a comparative analysis of implied volatilities from the Black‐Scholes model, Heston’s model, the MFIV, and VKOSPI for their abilities to forecast future volatility. The results of the empirical analysis of the KOSPI 200 options market indicate that Heston’s model can eliminate most of the bias associated with the Black‐Scholes model, whereas the MFIV and VKOSPI do not show any improvement in terms of forecasting performance.
A Decision Making Tool For The Improvement Of Service Quality At Universities

There have been numerous studies conducted on the evaluation of service quality at universities. However, there remains a deficiency on using a Multi Criteria Decision making approach in determining factors to consider for the improvement of service quality at a university. The purpose of this paper is to report on the use of Analytic Hierarchy Process (AHP) as a decision making tool in determining factors to consider for the improvement of service quality at a university. The study adopted a mixed method methodology and an action research approach was employed. A purposive convenient sample of 30 participants was used. Data was collected via questionnaires and face-to-face interviews. The data was captured in the software Expert Choice and the results were processed by taking the aggregated group judgements as the geometric mean of the individual comparisons. The findings reveal that organisational and educational issues are paramount to providing an effective service at tertiary institutions.
Translating Natural Language Competency Questions into SPARQLQueries: A Case Study

Ontology validation is an important part of measuring the quality of an ontology, and the best way to assure the accuracy of the knowledge encoded in the ontology. One of the earliest approaches toward ontology evaluation was the introduction of competency questions, i.e., natural language questions that the ontology should be able to answer. Since the ontology is a machine readable representation of knowledge, end-users should be able to query it using a formal language, such as SPARQL; however, translating natural language competency questions into SPARQL queries is not a trivial task. In the scope of this paper, we consider competency questions of HERO (Higher Education Reference Ontology) ontology we have developed. We translated these competency questions into SPARQL queries using a variation of a known approach. Keywords-Competency question; SPARQL query; Ontology validation; translation.
CMIP 5 pattern library for temperature and precipitation : description and methodology

Pattern scaling is used to efficiently emulate general circulation models and explore uncertainty in climate projections under multiple forcing scenarios. Pattern scaling methods assume that local climate changes scale with a global mean temperature increase, allowing for spatial patterns to be generated for multiple models for any future emission scenario. For uncertainty quantification and probabilistic statistical analysis, a library of patterns with descriptive statistics for each file would be beneficial, but such a library does not presently exist. Of the possible techniques used to generate patterns, the two most prominent are the delta and least squares regression methods. We explore the differences and statistical significance between patterns generated by each method and assess performance of the generated patterns across methods and scenarios. Differences in patterns across seasons between methods and epochs were largest in high latitudes (60–90 N/S). Bias and mean errors between modeled and pattern-predicted output from the linear regression method were smaller than patterns generated by the delta method. Across scenarios, differences in the linear regression method patterns were more statistically significant, especially at high latitudes. We found that pattern generation methodologies were able to approximate the forced signal of change to within ≤ 0.5 C, but the choice of pattern generation methodology for pattern scaling purposes should be informed by user goals and criteria. This paper describes our library of least squares regression patterns from all CMIP5 models for temperature and precipitation on an annual and sub-annual basis, along with the code used to generate these patterns. The dataset and netCDF data generation code are available at doi:10.5281/zenodo.495632.
Ship rat Rattus rattus eradication on Nahkapw Island, Federated States of Micronesia, Pacific Ocean

As part of a larger project attempting to reduce predation pressure from introduced rats Rattus spp. on native fauna and flora on several islands off Pohnpei main island (Pacific Ocean), a rat eradication program was undertaken on the small island of Nahkapw (1.58 ha). Prior to commencement of eradication, a pre-treatment rat population assessment was undertaken; only a single female ship rat R.rattus was caught (subsequently fitted with a radio-collar and released) and wax indicator success was also very low, suggesting that the island hosted a very low density of rats.
Technology and Journalism: Conflict and Convergence at the Production Level

At a time when new technologies are developing rapidly, the use of the term journalism has undergone various changes. The Internet allows information to “travel” in huge packs and the only restriction lies in the speed of electrons or electromagnetic waves (Osborn, 2001 : 1). The Internet has transformed the journalistic profession but technology alone is not enough to further address the significance of these changes. The role of journalism in democracy, political participation, and social integration must be redefined within the framework of a society whose main feature tends to be individualization. Technology is the first step towards change. Traditional methods can now be combined to create new distribution channels. Despite the fact that similarities can be found between the alternative and dominant media, the extent of the phenomenon has taken on huge dimensions and cannot be ignored on this basis. The production conditions of journalism are changing in order to facilitate the recording of events and their subsequent distribution. Furthermore, access to initial information is now feasible for most citizens, who have become not only recipients but also providers of information. At the same time, new news sources have emerged, which have come to compete with dominant media. Various issues arise through this combination of technology and journalism. One of these is trust, which, on the one hand, may be the bottom line, but, on the other hand, is extremely difficult to achieve within the new world order. Furthermore, agenda setting and the role of the gatekeeper cannot be excluded from the discussion. Moreover, issues relating to corporate dominance and the method of determining economic factors also raise questions. Within this framework, we will try to make an extensive analysis of the role of technology in the present day, the changes journalism has undergone during its transition
The effect of the golden ratio on consumer behaviour

This paper evaluates the relationship between the "golden ratio" and consumer aesthetic preferences, and investigates its possible implementation into market offer. Due to the increasingly diverse offer to which consumers are exposed, each detail of the offer should be in the function to attract consumer’s attention. These requirements increase the importance of design. Package design should facilitate the raise of 'usual' products to the level of 'unusual' products. Different forms of frontal sides of packages were created in the proportion of the golden ratio for research purposes. By setting simplegeometric shapes, with the absence of colors and other elements which may distract consumer’s attraction, a solution was created with the aim to direct the attention to proportional ratio of both the package form and graphical solution, instead of other visual elements. The achievement of "commercial beauty" as simultaneous effect of "aesthetic beauty and economic good" is also important from the aspect of our study. It is about different effects, products, services and relationships in mass consumer culture. This research offers answers to the question of consumer preferences related to package design based on the proportion of the golden ratio. Key words: Marketing, consumer behavior, the golden ratio, aesthetic preferences.
Verification of applicability of ABB robots for trans-planting seedlings in greenhouses

Trans-planting seedlings of flowers and vegetables in greenhouses can be ranked among the stationary cropping processes. When tomatoes are growing, it is necessary to replant them from the pre-plant ing containers to bigger silvicultural packets after approximately 15 days. This process is provided by the staff without any mechanisation in the small and middle businesses. The seedlings are taken out by hand together with the ball of soil from the preplanting containers and then they are planted into bigger silvicultural packets with a dibber. in special growing seedlings businesses (Montano Valtr, s.r.o. and Zahradnictvi Lysa nad Labem-Litol), flowerpot machines are used. These machines stream the replant process. They fill in the silvicultural bin with the soil and then dig a hole. The whole process is easier but the manual work is necessary even here because the seedlings have to be put in manually. This paper is aimed at this work. The fact that industrial Robots and Manipulators (henceforth iR+M) can be used for this operation has been pointed out by a number of authors. it was already Krutz (1983) who recommended the application of R+M for trans-planting seedlings, mainly due to the monotonous character of this work.
Studies on potentiality of some mango varieties in West Bengal.

Potentiality of twenty four less known mango varieties was studied for twenty three quantitative characters. Wide range of variations were observed in different characters among different varieties. High yields were recorded in varieties Nababhog (134.59 kg/plant), Mithua (98.64 kg/plant) and Khota lagga (95.95 kg/plant). Fruit weight, pulp weight and fruit size were found higher in Durgabhog, Gopibhog, Dhumma, Ashu Guti and Nababhog from nutritional point of view, ascorbic acid content was satisfactory in the varieties Nababhog, Mithua, Durlavbhog, Gopibhog, Gour and Subodh Guti but TSS/acid ratio was found higher (> 80) in Baro Langra Guti, Subodh Guti, Nababhog, Dudh Kumar, Khota Lagga, Ghia, Mithua, Gour and Durgabhog. The study suggests that some of the less known varieties have good potentiality for commercial exploitation
Re-testing PISA students one year later . On school value added estimation using PISA – OECD ♣

Thanks to the effort of local educational authorities, in two regions of North Italy (Valle d’Aosta and Provincia Autonoma di Trento) the PISA 2009 test was readministered to the same students one year later. In this paper we investigate the potential advantages of re-testing the same students in order to provide better measures of school contribution to students’ achievement. We show that while crosssectional measures of school value added based on PISA student literacy, which measures “knowledge for life”, tend to be very volatile over time whenever there is a high year-to-year attrition in the student population, longitudinal measures of school value added tend to be very robust to student attrition (even without controlling for sample selection). Moreover, persistence in test scores tends to be higher in highselectivity school environments. [JEL. I21 J24]
Determinants of Bank Credit in Small Open Economies: The Case of Six Pacific Island Countries

This paper examines the changes in bank credit to private sector across six economies in the South Pacific. An extensive time-series and cross-country panel data allow us to draw new and broader lessons compared to existing research, which have tended to focus mostly on single countries with shorter time periods. Results show that rising average lending and inflation rates may be detrimental to credit growth, and that deposit and asset size contribute positively to credit growth. Results also indicate that stronger economic growth leads to higher credit growth. A number of policy implications emerge and are also discussed.
SINGLE NUCLEOTIDE POLYMORPHISMS OF LIPOPROTEIN LIPASE GENE AND ITS ASSOCIATION WITH MARBLING QUALITY IN LOCAL SHEEPS

Lipoprotein lipase (LPL) is a key enzyme that plays in metabolism and transport lipoprotein andtherefore has an influence on blood triglyceride levels. LPL controls triacylglycerol partitioning betweenadipose tissue and muscle that increases fat storage or provides energy in the form of fatty acids formuscle growth. The research was aimed to explore Single Nucleotide Polymorphisms of LPL gene andto associate SNP with marbling quality. A total of 66 genomic DNAs consisted of sumatera thin-tail edsheep (50 heads) and garut sheep (16 heads) were used in this study. Polymerase Chain Reaction wasused to amplify genomic DNA and direct sequencing method was to identify polymorphism sequences.The sequences were analyzed with Bio Edit and MEGA 5.2. The BLAST sequence was obtained fromgene bank X.68308. 1. The association between the genotype and marbling quality was analyze by oneway ANOVA and further between mean differences were tested using least sgnificant difference. Theresults showed that 3 novel SNPs i.e. insertion g.26>C; insertion g.27> G and c.192T>C on garut sheepand a SNP insertion g.26>C/G on sumatera thin-tail ed sheep. The diversity of LPL gene at c.192T>Cwas associated with heneicosanoic acid, whereas TT genotype (0.04%) was higher than CC (0.03%) andCT (0.02%).
Vitamin D Levels and Depressive Symptoms’ Severity Among University Employees in Lebanon

BACKGROUND: Despite the evidence that the association between serum vitamin D level and susceptibility to depression is altered by ethnicity and vitamin D receptor gene polymorphisms, high prevalence of vitamin D deficiency, and parallel substantial burden of depression among Middle Eastern/ Arab adult populations, research exploring whether low serum vitamin D level is associated with increased risk of depression among Arab adult populations is almost non-existent.OBJECTIVE: This study aims to investigate the relationship between serum vitamin D levels and severity of depressive symptoms among a sample of healthy Lebanese adults, controlling for multiple confounders.METHODS: A total of 351 employees at a private university in Lebanon were surveyed. Information about sociodemographic, lifestyle habits, medical/ family history; and depressive symptoms were collected using a background questionnaire, international physical activity questionnaire –short form, and Patient Health Questionnaire, respectively. Anthropometric measurements and fasting blood samples were collected using standard methods. Serum 25-hydroxyvitamin D [25(OH)D] levels were measured by means of ELISA. Multiple linear regression analyses were conducted. A p-value of less than 0.05 was considered statistically significant.RESULTS: Sample mean age was 42.36 years. In the fully adjusted model, higher depression scores were found to be border-line significantly (p= 0.058) associated with lower serum 25-(OH)D levels and significantly associated with younger age, female sex, lower income, chronic illness diagnosis, family history of mental illness, number of stressful life events, and intake of antidepressants.CONCLUSION: We did not find any significant independent association between serum 25(OH)D levels and severity of depressive symptoms in a sample of Lebanese employees of a private university.
Distribution and Diversity of Coliform Bacteria in Estuary of Jiahe River, China

Waterborne outbreaks of pathogenic bacteria from contaminated water are serious threats for public health. Coliform bacteria have been regarded as one of the most important indicators for monitoring pathogenic bacteria. To address potential pathogenic bacterial outbreaks, the distribution and diversity of coliform bacteria in Jiahe river, which flows through densely-populated urban area in China, were detected. Escherichia Coli and other coliform bacteria were counted using the membrane filter technique to describe the distribution of the coliform bacteria. Phylogenetic analysis was applied to investigate the diversity of the coliform bacteria. The results suggested that the quantities of coliform bacteria varied greatly between five sampling sites with the highest value at site YT4 and the lowest value at site YT2. Highest concentrations of E. coli and other coliform bacteria were also observed at YT4, while the lowest value was detected at sites YT3 and YT2, respectively. Various coliform bacteria were classified by phylogenetic analysis, including Citrobacter, Klebsiella, Enterobacter, and Raoultella. Components of coliform bacteria affiliated into these four genera were various in all sampling sites. The statistical analysis suggested that the distribution of coliform bacteria were remarkably influenced by total bacteria amount. Multiple environmental parameters were proved to affect the diversity of coliform bacteria. The results of this study revealed the correlation between coliform bacteria and the environmental parameters, which is important for predicting and preventing waterborne transmission of pathogenic bacteria.
