Comparative morphology and ecology of the Pelophylax esculentus complex in Croatia

The Eurasian Pelophylax esculentus hybridogenetic complex, including Pelophylax ridibundus (R), P. lessonae (L), and their hybrid P. kl. esculentus (E), is considered to be one of the most complicated animal hemiclonal systems. It has been attracting the attention of evolutionary and molecular biologists as well as ecologists for decades. Despite the considerable number of studies describing population structure, reproductive modes, and distribution of the species complex, data on the rarely observed REL scenario, i.e., the presence of all three species at one site, are lacking. This study compared the morphological (morphometry, external morphology) and ecological (diet) profiles of all three species from a REL complex population located in the northwestern part of Croatia (Bjelovarsko-Bilogorska County). In terms of external morphology, the species varied interspecifically, but some features, for example, the yellow or green femoral colouration found in P. ridibundus, had not been expected. All three species exhibited a strong predilection for terrestrial prey, but interspecific differences were noticed. This paper aims to provide a better and more comprehensible insight into the ecological relationships of the REL complex, allowing comparisons with other study areas across Europe.
Contextualising a New Approach to Learning: Some comments on Yrjö Engeström's theory of expansive learning

Yrjo Engestrom’s research over the last decade has revitalised learning theory and taken it far beyond the narrow con nes of behaviourism and cognitivism with their focus on the individual learner in isolation from any context in which learning might take place. Also, unlike other research which emphasises the importance of studying learning in the natural (and usually non-school) contexts where it takes place, Engestrom work has shown that even in workplaces, where no one is formally allocated a teaching role, issues of pedagogy are important, either implicitly or explicitly in the promotion of what he refers to as expansive learning. The comments that follow are very much  rst thoughts, designed to open a dialogue between his ideas and the concerns of VET (Vocational Education and Training) researchers and practitioners. I want to begin, therefore, by setting my comments in the context of some of the issues currently facing those involved in VET. Inevitably the issues that I identify re ect my UK experience; however my involvement in two EU funded projects within the Leonardo de Vinci Programme gives me con dence that similar issues, sometimes in a less extreme form, are emerging in other European countries.
Broylerlerde Diyetteki Yağ Kaynaklarının Performans, Serum Kortikosteron Düzeyi, Antikor Titresi ve IFN-γ Gen Ekspresyonu Üzerine Etkileri

The present study was performed to evaluate the effects of addition of fish oil, soybean oil and olive oil to diet on performance and immune response in broiler chickens. In a completely randomized design, 320 broiler chickens (Ross 308, 7 days old) were allocated to four dietary treatments (control and three vegetable oils), four replicates with 20 chicks per each. The results showed that body weight gain of chicks fed soybean oil was higher and feed conversion ratio was better than the other treatments in the total period (P 0.05). Chicks fed fish oil had higher relative weights of bursa of Fabricius and there were no significant differences in relative weights of spleen among treatments. It was concluded that the source of oils in the diet may be affect the performance and immune response, the addition of fish oil and soybean oil to the diet resulted in significant improvement of performance and immune response in broiler chickens, respectively.
Credit Default Modeling: a Logit Approach

This paper aims at developing a credit scoring model that can best be used to ascertain the credit score and predict probability of default of firms seeking credit. The study subsequently aspires to find the financial ratios that can best be used to successfully construct the credit score and predict default risk. To achieve these purposes, the paper applied the logit model. Performance of the model was assessed using the percentage correctly classified (PCC) and the area under the receiver operating characteristic curve (AUC). The results show that the logit model yield very good performance rate for credit scoring and risk assessment. Further empirical evidence indicates that ratios bordering on: interest coverage, liquidity, activity, and firm size are those that can be significantly helpful in scoring credit applicants and assessing credit risk. Practically, the model can aid in reducing the time spent on evaluating credit applicants, and can give an exact default-risk intensity of each firm subjected to the model as well as serve as an early warning system. The multiplier effect will be a significant improvement in loan portfolio quality of the model user which is in accordance with the Basel II framework. Keywords: Credit default modeling, logit, Ghana
Multiple Outflows and Protostars near IC 348 and the Flying Ghost Nebula

Using optical (Hα, [S II], and i′), near-IR (H2, J, H, and KS), mid-IR (Spitzer Space Telescope IRAC 4.5 μm), and submillimeter (850 and 450 μm) data, we have examined the region surrounding the IC 348 cluster and the neighboring "Flying Ghost Nebula" (FGN) and found a multitude of shocks from protostellar outflows including HH 211, which had previously not been detected in visible wavelength images. We have identified 13 protostars in the region that drive protostellar outflows. The region surrounding the FGN is rich in ongoing star formation, with a number of outflows similar to those found in other sites of moderate star formation in Perseus (e.g., L1448, L1455, and Barnard 1). We have also found a candidate bent jet in this region. The axis defined by the bending angle suggests that this source may have been ejected from a multiple star system near the IC 348 IR source.
Obstructive and restrictive lung function abnormalities occur in SCD children SCD children have increased pulmonary capillary blood volume (PCBV) Respiratory system resistance and PCBV were measured before/after transfusion Respiratory system resistance and PCBV significantly increased post transfus

Lung function abnormalities occur in children with sickle cell disease (SCD) and may be associated with elevated pulmonary blood volume. To investigate that association, we determined whether blood transfusion in SCD children acutely increased pulmonary capillary blood volume (PCBV) and increased respiratory system resistance (Rrs5). Measurements of Rrs5 and spirometry were made before and after blood transfusion in 18 children, median age 14.2 (6.6 18.5) years. Diffusing capacity for carbon monoxide and nitric oxide were assessed to calculate the PCBV. Post transfusion, the median Rrs5 had increased from 127.4 to 141.3% predicted (p < 0.0001) and pulmonary capillary blood volume from 39.7 to 64.1 ml/m2 (p < 0.0001); forced expiratory volume in one second (p=0.0056) and vital capacity (p=0.0008) decreased. The increase in Rrs5 correlated with the increase in PCBV (r=0.50, p=0.0493). Increased pulmonary capillary blood volume may at least partially explain the lung function abnormalities in SCD children.
MIMO Antennas for Smart 5G Devices

This paper presents the design of <inline-formula> <tex-math notation="LaTeX">$8 \times 8$ </tex-math></inline-formula> multiple-input multiple-output (MIMO) antennas for future 5G devices, such as smart watches and dongles. Each antenna of the MIMO configuration occupies <inline-formula> <tex-math notation="LaTeX">$3 \times 4$ </tex-math></inline-formula> mm<sup>2</sup> and is printed on the top layer of the substrate in the form of a rotated H-shaped patch. The substrate used for the design is a <inline-formula> <tex-math notation="LaTeX">$31.2 \times 31.2 \times 1.57$ </tex-math></inline-formula> mm<sup>3</sup>, Rogers RT-5880 board, with a dielectric constant of 2.2. The top layer of the substrate has eight MIMO antennas, whereas the bottom layer is composed of ground plane. The ground plane is an electromagnetic bandgap-based structure designed for the enhancement of gain and efficiency. Each antenna is fed from the bottom layer of the substrate through vias to avoid any spurious radiation. The MIMO antennas resonate at 25.2 GHz with a 6-dB percentage bandwidth of 15.6%. The gain attained by the antennas in the entire bandwidth is above 7.2 dB with a maximum value of 8.732 dB at the resonant frequency. Likewise, the value of efficiency attained by the antennas in the entire bandwidth is above 65% with a maximum value of 92.7% at the resonant frequency. The simulation and measurement results have substantiated a good performance of the MIMO antennas, thus making them suitable for compact 5G devices.
Exploiting Social Annotations for Personalizing Retrieval

Continually, search engines improve their capabilities toward facilitating search and the retrieval enhancement. Despite the great efforts in the information retrieval field, the retrieved results may be out of user’s expectation. This may be due to the huge number of web resources, and unidentified user’s interests and domain. This paper proposes exploiting social annotations for improving retrieval based on personalization. The personalization focuses on web resources and retrieval process. In this context, new layer of knowledge is added to the web resource analysis and retrieval. Then, the additional knowledge leads to improve the retrieved results to be close to user’s interests. So, it retrieved different results for the same query based on the user’s interests. By applying the system, the experiments realize 36% precision improvement compared to non-personalized search engine. Moreover, the user satisfaction measured by evaluating search results versus user’s priorities, where it was in between 92% up to 100%.
On the Number of Sparse RSA Exponents

Abstract An RSA modulus is a product M = pl of two primes p and l . We show that for almost all RSA moduli M , the number of sparse exponents e (which allow for fast RSA encryption) with the property that gcd( e , ϕ ( M ))=1 (hence RSA decryption can also be performed) is very close to the expected value.
Potential of High-Resolution Satellite Imagery for Mapping Distribution and Evaluating Ecological Characteristics of Tree Species at the Angkor Monument, Cambodia

Abstract Large trees play several vital roles in the Angkor monuments landscape. They protect biodiversity, enhance the tourism experience, and provide various ecosystem services to local residents. A clear understanding of forest composition and distribution of individual species, as well as timely monitoring of changes, is necessary for conservation of these trees. using traditional field work, obtaining this sort of data is time-consuming and labour-intensive. This research investigates classification of very high resolution remote sensing data as a tool for efficient analyses. QuickBird satellite imagery was used to clarify the tree species community in and around Preah Khan temple, to elucidate differences in ecological traits among the three dominant species (Dipterocarpus alatus, Lagerstroemia calyculata and Tetrameles nudiflora), and to identify crowns of the dominant species. Population structures of trees were determined using a 14.26ha study plot. Species name, DBH, height, height under the crown and crown area were recorded for all trees over 40 cm in DBH. Tree locations were also recorded so as to provide references for the imagery analysis. Ecological traits of the dominant species were estimated using regressions by an expanded allometric equation for both large and small trees, based on DBH, height, height under the crown and crown width. The total number of species in the study plot was 45. From a spatial perspective, the three dominant species over 100 cm in DBH were segregated from each other. D. alatus, L. calyculata and T. nudiflora were concentrated, respectively, along the approach to the temple, near the centre of the complex, and on the walls of the monument. Object Based Image Analysis (OBIA) conducted using QuickBird satellite imagery, showed that crowns of D. alatus were largely determined by maximum of NIR layer and mean of digital number in panchromatic layer. Differences in the parameters for both asymptotic height and spatial distribution among the dominant species, result from differences in ecological traits, and enhance the value of the tourism resource by providing a dramatic shift of forest scenery that can be enjoyed by visitors to the monument.
Sentiment Analysis on Embedded Systems Blended Courses

Massive Open Online Courses (MOOCs) have been producing an electrified feeling in the academic circles since 2012. This was amplified once profit initiatives like Coursera and Udacity joined their forces with renowned universities like Stanford, Harvard and the Massachusetts Institute of Technology. This paper presents a modality of integrating Embedded Systems MOOCs into blended courses, but at the same time it provides an evaluation of this approach: the sentiment analysis technique. Such an evaluation not only reveals the polarity, but also valuable insights into improving the course content and integration of MOOCs into the intricacies of teaching embedded systems.
Concept And Implementation of Pes Program in the Cidanau Watershed: A Lesson Learned for Future Environmental Policy

Objective of the paper is to depict the concept of PES (Payment for Environmental Services) and its implementation in the Cidanau Watershed. This paper is a success story of PES implementation starting from the early adoption of the concept. The study shows that PES has impressed by many institutions, which was then initiated by PT KTI (Krakatau Tirta Industri) as a pilot project of the concept implementation. The main practice of PES implementation activities was promoting conservation farming, including transfer of conservation technology and trees growing. The conservation farming showed good development, which was characterized by more trees planted, more conservation technology applied, and more optimistic expectation for income increase. Moreover, PES Program will not only attract the farmers who participated in the program, but also other farmers who were not included in it. With such promising performance, PES Program can potentially be adopted by farmers and provide solution to various problems encountered in the Cidanau Watershed.
A Search for H2O Maser Emission in Southern Active Galactic Nuclei and Star-forming Galaxies: Discovery of a Maser in the Edge-on Galaxy IRAS F01063–8034

We report the cumulative results of five surveys for H2O maser emission at 1.35 cm wavelength in 131 active galactic nuclei (AGNs) and star-forming galaxies, conducted at the Parkes Observatory between 1993 and 1998. We detected one new maser, in the edge-on galaxy IRAS F01063-8034, which exhibits a single ~0.1 Jy spectral feature at 4282 ± 6 km s-1 (heliocentric) with an unusually large 54 ± 16 km s-1 half-power full width. The centroid velocity of the emission increased to 4319.6 ± 0.6 km s-1 (38 ± 2 km s-1 width) over the 13 days between discovery and confirmation of the detection. A similarly broad-line width and large change in velocity has been noted for the maser in NGC 1052, wherein jet activity excites the emission. Neither optical spectroscopy, radio-infrared correlations, nor infrared colors provide compelling evidence of unusual activity in the nucleus of IRAS F01063-8034. Since the galaxy appears to be outwardly normal at optical and infrared wavelengths, detection of an H2O maser therein is unique. The maser emission is evidence that the galaxy harbors an AGN that is probably obscured by the edge-on galactic disk. The detection highlights the possibility that undetected AGNs could be hidden in other relatively nearby galaxies. No other maser emission features have been identified at velocities between 3084 and 6181 km s-1.
Molecular phylogeny, systematics and morphological character evolution in the Balkan rissooidea (Caenogastropoda)

Morphological characters in 33 Balkan rissooid genera (Adriohydrobia, Adrioinsulana, Alzoniella, Anagastina, Belgrandiella, Bithynia, Boleana, Bythinella, Bythiospeum, Daphniola, Dianella, Emmericia, Graecorientalia, Graziana, Grossuana, Hauffenia, Heleobia, Horatia, Hydrobia, Islamia, Lithoglyphus, Litthabitella, Marstoniopsis, Orientalina, Paladilhiopsis, Parabythinella, Pontobelgrandiella, Pseudamnicola, Pseudobithynia, Pyrgula, Sadleriana, Trichonia, Ventrosia) are discussed and illustrated based on the literature and, where necessary, on the presented additional data. These include shell macrocharacters, protoconch sculpture, soft part morphology and pigmentation, radulae, stomach, female reproductive organs, male reproductive organs. Based on partial sequences of the ribosomal 18S RNA gene, a molecular phylogeny is presented for all the genera, and based on fragments of CO1 gene in mitochondrial DNA, for all except six genera. Based on the Adams consensus tree the two gene phylogenies are summarised and systematics of the group is proposed. Adrioinsulana is considered a junior synonym of Pseudamnicola; Parabythinella a junior synonym of Marstoniopsis; a new name: Radomaniola n. gen. is proposed as a replacement name for the preoccupied Orientalina. Litthabitella, morphologically and molecularly distinct from the hydrobioids, probably belongs to the Assimineidae. Marstoniopsis belongs to the Amnicolidae, Bythinella to Bythinellidae, Lithoglyphus to Lithoglyphidae, Heleobia to Cochliopidae, Bithynia and Parabithynia to Bithyniidae, Emmericia to Emmericiidae. Paladilhiopsis and Bythiospeum belong to the Moitessieriidae, there being no reason for homologising the two genera. All the other genera belong to the monophyletic family Hydrobiidae, within which two subfamilies can be distinguished: Hydrobiinae and Sadlerianinae. The latter includes mostly very closely related genera, which makes splitting of this subfamily into more groups of this rank unjustified. The phylogeny of the molecular characters is mapped on two molecular trees. The caecal appendix on the stomach, reduction of the basal cusps on the rhachis and the so called “spermathecal duct” evolved parallelly, and are thus homoplastic. The network of pores on the protoconch and the flagellum seem to be uniquely derived. The seminal receptacles and lobes on the penis seem to be phylogenetically old, not prone to changes and rather useful in phylogeny reconstruction. The morphologically inferred relationships of Emmericiidae and the systematic position of the two species of Parabythinella are discussed in Appendix 2 and Appendix 3, respectively. Destroyed type localities of Balkan rissooids are listed in Appendix 4.
Economic losses due to insect pests on avocado fruit in the Nelspruit/Hazyview region of South Africa during 1991

A survey of insect damage to 61 036 avocado fruits of five cultivars, was conducted at eight packhouses in the Nelspruit/Hazyview region. Stink bugs [incl Nezara viridula (L)], coconut bug [Pseudotheraptus wayi Brown], fruitfly [Pterandrus rosa (Karsch) and Ceratitis capitata (Weidemann)], thrips [Heliothrips haemorrhoidalis Bouche and Selenothrips rubrocinctus (Giard)], and false codling moth [Cryptophlebia leucotreta (Meyrick)] were the most important pests responsible for 84,10% of the damage recorded. The South African avocado industry is losing up to R2,93 million per annum due to insect pests in the Nelspruit/Hazyview region. A comparison between this study and that of the 1990 avocado season, confirms the importance of the above five pests and the seasonal variation in pest attacks between cultivars. Hass showed the greatest overall incidence of insect pest attack. The insect pest-complex was increased with the addition of three new pests recorded as damaging, or present on, avocado fruit
Predicting turnover intention: Do organizational support and organizational commitment play a role?

This paper reports research investigating factors that might influence employees’ turnover intention.The study was a cross sectional study where respondents’ perception was measured at one point in time. 105 respondents participated in this study. Two factors, namely organizational support and organizational commitment (affective commitment and continuance commitment) were tested to predict turnover intention among employees in the company.Results from the study reveal that only affective commitment has the strongest influence on turnover intention. The findings were discussed and implications were also put forward.
Statistical Inference in Possibly Integrated/Cointegrated Vector Autoregressions: Application to Testing for Structural Changes

We develop a new approach of statistical inference in possibly integrated/cointegrated vector autoregressions. Our method is built on the two previous approaches: the lag augmented approach by Toda and Yamamoto (1995) and the artificial autoregressions by Yamamoto (1996). We show that our estimator is asymptotically normally distributed irrespective of whether the variables are stationary or nonstationary, and that the Wald test statistic for the parameter restrictions has an asymptotic chi-square distribution. Using this method, we also propose to test for multiple structural changes. We show that our test statistics have the same limiting distributions as in the standard case, irrespective of whether the variables are stationary, purely integrated, or cointegrated.
