Large scale landslide susceptibility assessment using the statistical methods of logistic regression and BSA – study case: the sub-basin of the small Niraj (Transylvania Depression, Romania)

Abstract. The existence of a large number of GIS models for the identification of landslide occurrence probability makes difficult the selection of a specific one. The present study focuses on the application of two quantitative models: the logistic and the BSA models. The comparative analysis of the results aims at identifying the most suitable model. The territory corresponding to the Niraj Mic Basin (87 km2) is an area characterised by a wide variety of the landforms with their morphometric, morphographical and geological characteristics as well as by a high complexity of the land use types where active landslides exist. This is the reason why it represents the test area for applying the two models and for the comparison of the results. The large complexity of input variables is illustrated by 16 factors which were represented as 72 dummy variables, analysed on the basis of their importance within the model structures. The testing of the statistical significance corresponding to each variable reduced the number of dummy variables to 12 which were considered significant for the test area within the logistic model, whereas for the BSA model all the variables were employed. The predictability degree of the models was tested through the identification of the area under the ROC curve which indicated a good accuracy (AUROC = 0.86 for the testing area) and predictability of the logistic model (AUROC = 0.63 for the validation area).
Optical variability of PKS 0736+017

We present BVR photometric observations of the blazar PKS 0736+017. These observations were carried out with three telescopes in Mexico and two in Spain between December 1998 and April 2003. PKS 0736+017 shows remarkable variation at different timescales and amplitudes. Maximum brightness was detected on December 19, 2001 (B=14.90±0.01, V=14.34±0.01, and R=13.79±0.01). A peculiar tendency to redden with increased brightness was detected throughout our observations. Moreover, in one season a good correlation between flux level and spectral slope is shown. This anomalous behaviour cannot be described by common flare models of blazars. The flux vs. spectral slope correlation observed in this and other blazars is worth further study.
Mycoremediation of Dichlorvos Pesticide Contaminated Soil by Pleurotus pulmonarius (Fries) Quelet

The extensive use of pesticides leads to accumulation of a huge amount of residues in the environment. As such, the present study investigates the potentiality of Pleurotus pulmonarius to bioremediate dichlorvos pesticides (2,2-dichlorovinyldimethylphosphate) in contaminated soil. DDVP-polluted soils have been contaminated in five concentrations (5% v/w, 10% v/w, 15% v/w, 20% v/w, and 25% v/w), and the soil samples have been inoculated and incubated with pure culture of growing spawns of P. pulmonarius, obtained from commercial mushroom laboratory of Federal Institute of Industrial Research Oshodi, Lagos. The control, however, has not been inoculated. Each treatment has been in triplicates with the soils, analyzed for total amount of DDVP at day 0 and day 60, using gas chromatography and mass spectrometry. Also, pH, moisture content, and total organic matter of the soil have been determined. Results show that the rate of DDVP degradation in the soils with Pleurotus pulmonarius has been higher than the soil samples without mushroom after 60 days. However, for the control without mushroom (loss due to natural attenuation) and those inoculated with P. pulmonarius (bioremediation) the loss percentage of DDVP ascended with the percentage of pesticide from 5% to 25%. The DDVP loss across all different concentrations of mushroom inoculation have been significant (p 0.05), except for the lowest pesticide level (5%). Activities of mycelia have decreased soil pH, moisture content, and total organic matter. There has been a very minimal pesticide bioaccumulation in mushroom tissue, which has not been significant (p>0.05), but considerable at p<0.001, indicating that P. pulmonarius has the potential to degrade DDVP pesticides in soil.
Using of Performance Appraisal Methods in Czech and Slovak Organisations

Purpose: People, their knowledge, abilities and skills are considered to be the most valuable source every organisation can exploit. It is, therefore, necessary to care about their fair remuneration and continuing development, as well as their objective and fair appraisal. Implementing an effective appraisal system in the personnel strategy, satisfying both employers and employees, is an essential part of the success of all competing organisations. The aim is to evaluate the use of employee appraisal methods in the selected Czech and Slovak organisations, and to recommend proposals for improvement on the grounds of such evaluation. Methodology/Approach: The data were obtained in two quantitative researches conducted in the selected organisations in the Czech Republic (n = 402) and the Slovak Republic (n = 339). Univariate analysis, bivariate analysis and analysis of qualitative traits were employed in order to evaluate results. Findings: The results showed that 58.46% of the interviewed Czech organisations and 69.32% of the Slovak organisations had established a formal system of employee appraisal. Most of them were medium-sized enterprises with an HR department, operating in the private sector. Research Limitation/implication: Limits can be seen in to focus on research in two selected countries, but they have comparable from historical, political and the job market perspectives. Originality/Value of paper: The article focused on using of modern performance appraisal methods in practice to build the employer’s good brand and attract knowledge workers.
Hiding in Plain Sight: A Consideration of NF1-Associated Hypovitaminosis D and its Treatment

This article deals with the autosomal dominant human genetic disorder, Neurofibromatosis Type 1 (NF1), and has three main foci. The first is the general principle that substantial advances in understanding the pathogenesis of a genetic disorder can derive from the timely reconsideration of material previously overlooked or otherwise not given its due. There are times when the key to a supposed “mystery” is hiding in plain sight. The second focus is the specific consideration of selected elements of an apparent vitamin D deficiency in NF1. And the third focus of this article reconsiders the mast cell in NF1 pathogenesis, including the potential of NF1 being a “mastocytosis” of sorts, with the prospect of additional grounds for treatment with mast cell blockers, for example, ketotifen.
Price Discovery in the Stock Index Futures Market: Evidence from the Chinese stock market crash

This paper examines time-varying price discovery of the Chinese stock index futures market during a stock market crash in 2015. We find that the index futures market plays a long-run leading role in terms of its higher static and dynamic generalised information share (GIS) than both the Shanghai and Shenzhen A share markets during the market turbulence. The expected trading volume in each market improves GIS of that market. The importance of trading activities by the majority of investors in increasing market efficiency during a crash is underscored. Government intervention on futures trading impairs price discovery in the futures market.
5D World-Universe Model. Neutrinos. The World

In this manuscript we discuss mass-varying neutrinos and propose their energy density to exceed that of baryonic and dark matter. We introduce cosmic Large Grains whose mass is about Planck mass, and their temperature is around 29 K. Large Grains are in fact Bose-Einstein condensates of proposed dineutrinos, and are responsible for the cosmic Far-Infrared Background (FIRB) radiation. The distribution of the energy density of all components of the World (protons, electrons, photons, neutrinos, and dark matter particles) is considered. We present an overview of the World- Universe Model (WUM) and pay particular attention to the self-consistent set of time-varying values of basic parameters of the World: the age and critical energy density; Newtonian parameter of gravitation and Hubble’s parameter; temperatures of the cosmic Microwave Background radiation and the peak of the cosmic FIRB radiation; Fermi coupling parameter and coupling parameters of the proposed Super-Weak and Extremely-Weak interactions. Additionally, WUM forecasts the masses of dark matter particles, axions, and neutrinos; proposes two fundamental parameters of the World: fine-structure constant α and the quantity Q which is the dimensionless value of the fifth coordinate, and three fundamental physical units: basic unit of momentum, energy density, and energy flux density. WUM suggests that all time-dependent parameters of the World are inter- connected and in fact dependent on Q. We recommend adding the quantity Q to the list of the CODATA-recommended values.
Avaliação da força de preensão palmar em atletas de jiu-jitsu de nível competitivo

It is a transversal and analytical study, whose objective was to evaluate the palmar grip strength in jiu-jitsu athletes in competitive level, with the purpose of establishing a functionality range for this population, considering that the number of athletes has been increasing. The subjects of the research were 100 individuals from the masculine gender divided in two groups (CG and GA) with age between 20 and 30 years. The group of athletes (GA) had 50 subjects and the control group (CG) had 50 subjects. The instrumental used in the study was the dynamometer JAMAR  . Regarding the average of the prehension strength recorded in the study groups, there was a significant predominance (p<0,05) in the GA in comparison to the GC only for the left hand. In the first group, there was a trend of a increasing the strength as the measurement were taken, while in the second one, this trend was reverted. We concluded that jiu-jitsu athletes do not present high values of palmar grip strength, being that the jiu-jitsu practice suggests that occur physiological causes alterations characterized by the increase of the ability of resistance in the movement of prehension. The results obtained must be considered as an indication of strength for rehabilitating the manual function of the Jiu-Jitsu athlete.Keywords - Leadership, soccer, coaching. abstract - Jiu-jitsu, palmar grip strength, evaluation, dynamometer.
The Effect of International Trade and Wages of Skilled and Unskilled Workers: Evidence form Brazil

This paper assesses the impact of trade on wages of skilled and unskilled workers in developing countries and presents new evidence for Brazil. The relation between trade and wages has been analyzed using a new econometric model that links (sectoral) trade intensity ratios of Brazilian states to wages of individuals active in the corresponding state (and sector), while controlling for individual characteristics. The findings are interpreted using trade theories of Melitz and Hekscher & Ohlin and show that imports have negatively affected wages of the skilled and unskilled, but disproportionately those of the skilled. Furthermore, exports seem to have positively affected wages of the skilled and unskilled, but disproportionately those of the unskilled. These results are in line with the theories of Melitz and Hekscher & Ohlin.
Unsupervised Spelling Correction for the Slovak Text

This paper introduces a method to automatically propose and choose a correction for an incorrectly written word in a large text corpus written in Slovak. This task can be described as a process of finding the best matching sequence of correct words to a list of incorrectly spelled words, found in the input. Knowledge base of the classification system statistics about sequences of correctly typed words and possible corrections for incorrectly typed words can be mathematically described as a hidden Markov model. The best matching sequence of correct words is found using Viterbi algorithm. The system will be evaluated on a manually corrected testing set.
The Influence of Digestate and Mineral Fertilisers on Yields and Content of Nitrates and Ascorbic Acid in Kohlrabi Bulbs

LOSAK TOMAS, ZLAMALOVA TEREZA, VITĚZOVA MONIKA, HLUSEK JAROSLAV, SKARPA PETR, FRYC JIŘI, VITĚZ TOMAS, MARECEK JAN. 2014. The Infl uence of Digestate and Mineral Fertilisers on Yields and Content of Nitrates and Ascorbic Acid in Kohlrabi Bulbs. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 62(1): 161–166. In a one-year vegetation pot experiment we compared the eff ect of the digestate from a biogas plant and mineral fertilisers on yield and quality parameters of kohlrabi, variety Moravia. Four treatments were used in the trial: 1) untreated control, 2) urea, 3) digestate, 4) urea, triple super phosphate, KCl, MgSO4. The rate of N was the same in treatments 2–4, i.e. 1.5 g N/pot. In treatment 4 the rate of P, K and Mg corresponded with the rate of these nutrients in the digestate treatment (3). The inhibited growth of kohlrabi a er the application of NPKMg (4) was obviously the consequence of early planting a er the application of fertilisers (5 days) and of the salinity of the small content of soil in the pot and resulted in the lowest weight of single bulbs (69 g), followed by the unfertilised control treatment (75 g). A er the application of the digestate (treatment 3) the weight of single bulbs signifi cantly increased (126 g) compared to the urea treatment (101 g) and all the other treatments. The content of ascorbic acid in the fertilised treatments did not diff er (441–458 mg/kg) but it increased signifi cantly compared to the unfertilised treatment (398 mg/kg). There were signifi cant diff erences among all the fertilised treatments (1–2–3–4) in the bulb nitrate content (346–1,147–815–1,091 mg NO3 −/kg fresh matter, respectively). A er digestate application their content decreased signifi cantly to 815 mg NO3 −/kg fresh matter. Digestate treatment resulted in comparable or better yields and qualitative parameters compared to all the other treatments.
Patterns of endemism in south‐eastern Pacific benthic polychaetes of the Chilean coast

Aim In this study we evaluate patterns of endemism for benthic polychaete species along the southeastern Pacific coast of Chile. Our goals were (1) to describe latitudinal gradients of endemism and identify areas of high endemism, (2) to evaluate the effect of biogeographical limits on endemism patterns, and (3) to evaluate indirectly the role played by evolutionary dynamics on patterns of endemism.
On the relation between reduced quantisation and quantum reduction for spherical symmetry in loop quantum gravity

Building on a recent proposal for a quantum reduction to spherical symmetry from full loop quantum gravity, we investigate the relation between a quantisation of spherically symmetric general relativity and a reduction at the quantum level. To this end, we generalise the previously proposed quantum reduction by dropping the gauge fixing condition on the radial diffeomorphisms, thus allowing us to make direct contact with previous work on reduced quantisation. A dictionary between spherically symmetric variables and observables with respect to the reduction constraints in the full theory is discussed, as well as an embedding of reduced quantum states to a subsector of the quantum symmetry reduced full theory states. On this full theory subsector, the quantum algebra of the mentioned observables is computed and shown to qualitatively reproduce the quantum algebra of the reduced variables in the large quantum number limit for a specific choice of regularisation. Insufficiencies in recovering the reduced algebra quantitatively from the full theory are attributed to the oversimplified full theory quantum states we use.
Non-conventional cement-based composites reinforced with vegetable fibers: A review of strategies to improve durability

The present review shows the state-of-art on the approachs about improving the processing, physical- mechanical performance and durability of non-conventional fiber-cement composites. The objective of this review is to show some of these strategies to mitigate the degradation of the vegetable fibers used as reinforcement in cost-effective and non-conventional fiber-cement and, consequently, to improve their mechanical and durability properties for applications in the housing construction. Beyond the introduction about vegetable fibers, the content of this review is divided in the following sections: (i) surface modification of the fibers; (ii) improving fiber-to-cement interface; (iii) natural pozzolans; (iv) accelerated carbonation; (v) applications of nanoscience; and (vi) principles of functionally graded materials and extrusion process were briefly discussed with focus on future research needs.
Internet and Labor Income: Places and Activities in Colombia

Despite the literature in the richest countries about the positive correlation between Internet and income, there is still an open question about the utility of this technology the developing world. This paper uses Propensity Score Matching and includes demographic and industry characteristics, which is the best possible way to control for the productivity of each worker. The matching model meets a broad common support, close gaps between control and treated individual after matching and holding the results for different matching techniques. The results present a positive and statistically significant correlation between Internet and income in Colombia. The key contribution of this paper is to show that the lowest wage premium for using Internet is in the middle of the skill distribution, as in the developed world. Nonetheless, Colombia differs to these countries in the tales of the skill distribution because the highest wage premium is for the lowest skill workers.
Antimicrobial effect of local medicinal plant extracts in the Kingdom of Saudi Arabia and search for their metabolites by gas chromatography-mass spectrometric (GC-MS) analysis

The present study was designed to evaluate the anti-microbial properties of leaf extract from some local plants in Saudi Arabia belonging to seven different families which areRumex vesicarius from the family Polygonaceae, Datura stramonium from the familySolanaceae, Zygophyllum coccineum from the family Zygophyllaceae, Citrullus colocyuthus from the family Cueurbitaceae, Lasiurus scindicus from the family Poaceaeand Heliotropium digynum from the family Boraginaceae against seven human pathogenic bacteria and yeast strains including Staphylococcus aureus ATCC 25923, Bacillus subtilisATCC 6633, Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853,Salmonella suis ATCC 13076, Shigella sonnei ATCC 11060, and Candida albicans ATCC 10231. The compounds were extracted using two different extraction agent water and acetone. The evaluation of the anti-microbial activities of the extracts was examined against all the aforementioned microorganisms by standard agar well diffusion method. The water extracts showed no antibacterial activities in all the different plant families, but as for the acetone's extracts, the antimicrobial activities were moderate to strong (about 18 to 30 mm). The compounds present in the extracts were identified by gas chromatography-mass spectrometry (GC-MS) analysis. The leaf extracts of the following medicinal plants were mainly found to contain compounds like 4-ethyl-2-hydroxycyclopent-2-en-1-one, 2-methoxy-4-vinylphenol, and cyclobutanol for R. vesicarius; hexanoic, nonanoic, octanoic, and heptanoic acid for D. stramonium; 1-hexyl-2-nitrocyclexane, 2-octadecyl-propane-1,3-diol, octadecanal, and cyclohexane for Z. coccineum; l-(+)-ascorbic acid 2,6-dihexadecanoate, eicosanoic acid, and 2-heptadecenal for C. colocyuthus; butanoic acid, 6-octen-1-ol,3,7-dimethyl-propanoate, 2-hydroxy-3,5-dimethylcyclopent-2-en-1-one, and alpha-cadinol for L. scindicus; and 5H-1-pyrindine indolizine, 7-acetyl-2-hydroxy-2-methyl-5-isopropylbicyclo, 1-hexyl-2-nitrocyclohexane for H. digynum. Key words: Antimicrobial activities, medicinal plant extract, agar well diffusion method, gas chromatography-mass spectrometry (GC-MS), Saudi Arabia.
Developing Brand Ambassadors: The Role of Brand-centred Human Resource Management

In this paper, we propose the role of brand-centered human resource management (HRM) in supporting the internal branding initiative toward the development of brand ambassadors in organizations. By brand ambassadors, we mean employees who are not necessarily involved in sales or marketing job, but who are also partly responsible for the promotion of the organization brand to external stakeholders, such as customers. Because the brand ambassadors are expected to live the brand and project the correct image of the company brand, it is vital that they understand and accept the brand value proposition. In order to help them do their job well in delivering the brand promise, it is essential that brand-centered HRM is instituted. Brand-centered HRM refers to the HR-related practices, such as hiring, training and development, performance appraisal, and compensation, to name a few, that are implemented to make employees produce positive attitude and behaviors toward the brands of the firm (Chiang et al., 2012). When the employees are able to play the role of good brand ambassadors to the external customers, it is expected that customers’ brand experience will be enhanced, resulting in customer brand loyalty. In essence, brand-centered HRM is key toward the accomplishment of brand success and survival in the marketplace as the external branding and internal branding strategies are aligned.
Optimization of stocking density for Azolla based carp polyculture pond

The study optimized the stocking density for Azolla based carp polyculture ponds under 3 different treatments like T1: 10000 fish ha-1, T2: 11500 fish ha-1 and T3: 12500 fish ha-1. Fishes (Hypophthalmichthys molitrix, Catla catla, Labeo rohita, Cirrhinus cirrhosus, Cyprinus carpio, Ctenopharyngodon idella and Barbonymus gonionotus) were also grown for a period of six months. Mean initial stocking weight of H. molitrix, C. catla, L. rohita, C. cirrhosus, C. carpio, C. idella and B. gonionotus were 60, 65, 58, 52, 61, 70 and 22 g respectively. There were 3 replications for each treatment under this experiment. Liming (250 kg ha-1) and basal fertilization (cow dung: 1500 kg ha-1, urea: 60 kg ha-1 and TSP: 60 kg ha-1) were done for all the treatments. Triple Super Phosphate (TSP) (2.5 kg ha-1day-1 in all treatments) was applied as periodic fertilization. Water quality parameters (temperature, transparency, DO, pH, alkalinity and free CO2) were monitored fortnightly and fish growth parameters (weight gain and Specific Growth Rate (SGR)) were monitored monthly. Economics (in terms of total cost, gross benefit, net profit margin and Cost Benefit Ratio (CBR)) of fish farming was also evaluated. No significant difference in the mean values of water quality parameters was found between the treatments. The significant difference (P<0.05) with the treatments was found in all the growth parameters except survival rate. Treatment T3 varied more significantly (P<0.05) for the mean values of total yield, but in terms of total cost, gross benefit, net benefit, net profit margin and CBR, treatment T1 (stocking density of 10000 fish ha-1) was found best. Findings indicated that the stocking density of 10000 fish ha-1 could be a good option for low cost Azolla based fish farming in Bangladesh.
