Skill among Retail Online Traders - A Bootstrap Analysis

This study examines the skill level of online traders investing in CFDs with help of bootstrap simulations. For this investigation, we orientate towards the paper of Fama and French (2010) in terms of the methodology for our social trading data set. Our data set from one of the largest social trading platforms in Germany allows us to analyse if skill exists among non-professional retail investors and hence, if investment talent prevails. We define traders as skilled when they are able to cover all costs related to their investments. Thereby, we reveal that in the aggregate, social traders are not skilled with regards to net returns. While this study suggests that investing in social trading does not pay off, we detect skilled social traders that are hidden by the large amount of unskilled social trading investors. For this reason, investors with already a small amount of skill are very valuable within an investment field of unprofessional retail investors. Therefore, we show that the selection of a social trader should be carefully motivated.
Workers’ Perceptions of Workplace Safety and Job Satisfaction

A lot of attention has beenfocused on workers ‘ perceptions of workplace safety but relatively little or no research has been done on the impact of job satisfaction on safety climate. This study investigated this relationship. It also examined the relationships between job satisfaction and workers’ compliance with safety management policies and accident frequency. A positive association was found between job satisfaction and safety climate. Workers who expressed more satisfaction at their posts had positive perceptions of safety climate. Correspondingly, they were more committed to safety management policies and consequently registered a lower rate of accident involvement. The results were thus consistent with the notion that workers ‘ positive perceptions of organisational climate influence their perceptions of safety at the workplace. The findings, which have implications in the work environment, are discussed.
Oral Candidiasis: A Histopathological, Ultrastructural and Immunohistochemical Study

Oral candidiasis presents characteristic histopathological findings. The mucous epithelium at the site of candidiasis is covered by a hyperkeratinized layer. But, the factors leading to hyperkeratosis in candidiasis were unknown. To investigate the factors which led to hyperkeratosis in oral candidiasis, we histopathologicaly, histochemicaly, and ultrastructualy observed the morphological alteration of the epithelial tissue, and studied the factors in connection with those changes immunohistochemically. Candidiasis group (8 cases of papilloma, 5 cases of verrucous hyperplasia), non-candidiasis group (8 cases of papilloma, 7 cases of verrucous hyperplasia), and 5 subjects with normal oral mucosa were selected. Ultrastructually, Candidal hyphe internalized into the epithelial cytoplasmic vacuole resembling endocytosis.Destruction of desmosomal cell junction and deficit of tonofilament was also observed at the tip of the hypha. Immunohistochemistry, weaker expression for E-cadherin was seen in the candidiasis group. Strong positive Ecadherin reaction was seen along the insertion sites of the hyphae. CK13 was negative in non-candidiasis group, and weakly positive in candidiasis groups in the basal layer, respectively. Weakly positive EGFR reactions were observed in the prickle layer in candidiasis group. Inflammatory reaction with NE, CD68, COX-2, CD105 and Ki-67 were markedly observed in candidiasis group. The above result suggested that the hyperkeratosis in oral candidiasis was related with Ecadherin in connection with adhesion and penetration of Candidal hyphae and the precocious expression of the stratified squamous epithelium later differentiated marker CK13. Furthermore, it was surmised that inflammatory response by Candidal hyphae invasion itself led to hyperkeratosis.
Growth, carcass and caecal traits in V-line and crossbred rabbit fed diets containing discarded dates

A total of 78 rabbits representing two genetic groups of V-line and crossbred of V-line x Saudi Gabali were used to evaluate dietary treatments containing discarded dates (DD) for post-weaning growth performance? feed consumption and conversion? carcass characteristics, caecal parameters, and blood constituents. In the control diet (C), no DD was added? while in the other diets DD were incorporated to replace partially barley? wheat bran? molasses and corn by 15% (D15 diet) or 30% (D30 diet). Feed conversion ratio at interval of 4-12 weeks was significantly in favour of the control diet. Carcass traits and caecal parameters were not significantly affected by any of the 3 dietary treatments. Total caecal bacterial count was significantly increased in favour of rabbits fed D30. Crude protein, ether extract and ash in the lean were in favour of the diets containing 15 or 30% DD; indicating an improvement of 5.3 or 3.9% in crude protein and 7.3 or 14.4% in ash relative to the control diet, respectively. Rabbits fed D30 recorded a significant decrease in the plasma cholesterol. Crossbred rabbits were heavier in body weights and gains than that of the V-line rabbits. Feed conversion ratios were in favour of V-line rabbits. Fat in carcass and meat to bone ratio in crossbred rabbits were significantly higher than that in V-line rabbits, while percentages of the lean and bone in V-line carcasses were higher. Caecal bacterial count in crossbred rabbits was lower than that in V-line rabbits. Carcass traits, tissues compositions, caecal parameters and blood constituents were significantly affected by interaction of dietary treatments with genetic groups, while most of the lean constituents were not affected. Crossbred rabbits fed D30 conversed feed lesser (2.57) than crossbred rabbits fed the other two dietary treatments since feed conversion ratio was 2.48 for C diet and 2.49 for D15 diet. But? V-line rabbits fed C diet conversed better (2.95) than V-line rabbits fed D15 or D30 since feed conversion ratio was 3.29 for D15 and 3.04 for D30.
Comparative haematology of ten species of marine fish from Visakhapatnam Coast

A comparative study has been made of haematological parameters (erythrocyte numbers, leucocyte numbers, haematocrit and haemoglobin), erythrocyte indices (MCV, MCH and MCHC) and cytometric measurements (cell and nucleus) of 10 species of marine fish from the Visakhapatnam Coast, of which six are from harbour waters, three from rock pools and one from inshore waters. It is found that active fish have high values of erythrocyte numbers, haematocrit, haemoglobin and nucleo/cytoplasmic ratio and low values of leucocyte numbers and erythrocyte cytosome measurements. The most active of all is the inshore species Rastrelliger kanagurta depicting the haematological requirements of an active fish with high oxygen demand to meet the requirements of high metabolic rate. The other active fish such as Megalops cyprinoides and Mugil cephalus are intermediate, with the rock pool fish and Caranx carangus with low values of nucleo/cytoplasmic ratio at the other extreme.
A comprehensive molecular phylogeny of tardigrades—adding genes and taxa to a poorly resolved phylum‐level phylogeny

Tardigrades constitute a phylum of miniaturized metazoans with ca. 1030 living species, a fossil record that probably dates back to the Cambrian, and physiological properties that allow them to live in almost any environment known to host life on Earth—they can also survive in space. Despite broad consensus regarding their membership of the superclade Ecdysozoa, the exact position of the phylum remains contested (some analyses suggest onychophorans and arthropods as their closest relatives, while others suggest a relationship to nematodes and nematomorphs) and the internal relationships of the phylum are still poorly understood. In the present study, we present a hypothesis of tardigrade relationships by examining more taxa and more markers than any previously published phylogeny of the group. We generated novel data for three markers (18S rRNA, 28S rRNA, COI) for 42 individuals of 16 carefully identified species, comprising 12 genera and five families from the classes Heterotardigrada and Eutardigrada, and analysed them in conjunction with nearly all data available from GenBank. Our results show certain disagreement with current taxonomy both at higher ranks (families, orders, classes) and at low (generic) taxonomic levels. When studying the sensitivity to outgroup choice, the class Eutardigrada was monophyletic under only one combination of outgroups; all other combinations placed the eutardigrade order Apochela as sister to the class Heterotardigrada. Phylogenetic relationships within the other eutardigrade order, Parachela, were stable to outgroup choice. Eutardigrade superfamilies recently proposed by Sands and collaborators in the order Parachela were tested with the introduction of new sequences from additional genera, and the possible morphological synapomorphies supporting those superfamilies are discussed.
The Effect of Humic-Fatty Acid Preparation on Production Parameters and Meat Quality of Growing Rabbits

The Effect of Humic-Fatty Acid Preparation on Production Parameters and Meat Quality of Growing Rabbits The aim of the study was to determine the effect of a humic-fatty acid preparation on production parameters and meat quality of rabbits. Three groups of New Zealand White rabbits were used (one control and two experimental) with 8 animals per group. The animals of group C (control) were fed standard pelleted diet, group H5 received a control diet supplemented with 5%, and group H10 a control diet with 10% humic-fatty acid preparation. The experiment was terminated after 6 weeks feeding, when rabbits were slaughtered. The experimental groups showed higher gains and a higher feed conversion ratio than the control group. The dietary inclusion of the experimental additive had a beneficial effect on the meat quality traits, such as Fe concentration, hardness and colour, but it also increased the susceptibility of fat to oxidative changes. Wpływ preparatu huminowo-tłuszczowego na parametry produkcyjne oraz jakość mięsa królików rosnących Badano wpływ preparatu huminowo-tłuszczowego na wskaźniki produkcyjne oraz jakość mięsa u królików. Materiał stanowiły króliki rasy nowozelandzkiej białej, które podzielono na trzy grupy po 8 zwierząt w każdej. Zwierzęta grupy kontrolnej były żywione standardową paszą granulowaną, grupy H5 - paszą z 5% dodatkiem preparatu huminowo-tłuszczowego, natomiast grupy H10 - paszą z 10% dodatkiem tego preparatu. Doświadczenie trwało 6 tygodni, po czym zwierzęta poddano ubojowi. W grupach doświadczalnych odnotowano wyższe przyrosty oraz wskaźniki wykorzystania paszy niż w grupie kontrolnej. Stwierdzono korzystny wpływ zastosowanego preparatu na parametry jakościowe mięsa, takie jak zawartość żelaza, twardość i kolor, jednocześnie jednak obserwowano wzrost podatności tłuszczu na zmiany oksydacyjne.
ULTRACYTOCHEMICAL CHANGES IN THE DISTRIBUTION OF ACID PHOSPHATASE AND THIAMINE PYROPHOSPHATASE ACTIVITY IN THE NERVE CELLS OF THE CEREBRUM OF THIAMINE-DEFICIENT RATS

Thiamine-deficient diet was given to male Donryu rats (ca. 100g.) and changes in acid phosphatase (ACPase) and thiamine pyrophosphatase (TPPase) activity were observed ultracytochemically in the nerve cells of the cerebral cortex up to 3 weeks after the onset of the experiment. The control rats (on normal diet containing thiamine) were also kept simultaneously.It was demonstrated by morphological preparations that the lysosomes were increased in number and enlarged in size in nerve cells as well as neuroglial cells of thiamine-deficient rats, and it was confirmed in the cytochemical preparations that these lysosomes possessed intense ACPase activity. Besides, many vacuolated lysosomes were also seen with ACPase activity indicating an increase in the lysosomal ACPase activity. In addition, the enzymatic distribution in the Golgi apparatus was also slightly increased. Overall increase in ACPase activity is thus noted in contrast to that of controls. Increase is related to autolysis. While TPPase activity revealed in the Golgi apparatus was inclined to decline in thiamine-deficient rat suggesting the decreased rate of thiamine metabolism.These enzymatic changes may be attributed to the early deficiency impairment of thiamine.
The Role of Foraging Profitability and Experience in Habitat Use by the Bluegill Sunfish

This study integrates laboratory and field results to interpret habitat use and switching by individual bluegill sunfish (Lepomis macrochirus). Prey handling and search times for the bluegill were determined from laboratory feeding experiments at different prey sizes and densities in open water and sediment habitats. Relationships were then constructed to predict the expected return per unit time foraging in these habitats. Experience (learning) was found to increase foraging efficiency up to fourfold over the course of six to eight foraging bouts. A population of 225 bluegills was then introduced into a pond consisting predominantly of open water and sediment habitats. This population exhibited several habitat switches as resources declined during the 3-mo experiment; in addition, the population split over a 5-wk period, with individuals specializing on one habitat or the other. These specialists were considerably more successful than habitat generalists as measured by average amount of food in the stomachs. Return rates estimated from the laboratory experiments indicated that the two habitats were nearly equal in foraging profitability. The individual specialization indicated that learning and mutually interfering foraging mechanisms were involved in the species' use of the two habitats. The results suggest that learning and sampling are important aspects of both habitat use and the specialization of individuals within a population.
Effect of different Agaricus species on the development of the mushroom sciarid fly Lycoriella ingenua

Isolates from eight species of Agaricus were investigated in laboratory experiments for their effect on the development of the mushroom sciarid fly, Lycoriella ingenua (Dufour) (Diptera: Sciaridae), which is an important pest of the white mushroom Agaricus bisporus (Lange) Imbach (Agaricaceae). The population levels of L. ingenua developing in compost inoculated with Agaricus mycelium varied with the Agaricus isolate used, with some isolates causing high levels of inhibition. The development of L. ingenua populations and the survival of larval instars were inversely proportional to the amount of Agaricus inoculum applied. There was also a negative relationship between L. ingenua survival and the extension rate of the Agaricus isolate in compost. The results suggest that inhibition of L. ingenua population development by Agaricus is linked to the rate at which compost is colonized by fungal mycelium. Therefore, on mushroom farms, sciarid fly control should focus on protection of the compost before it has become colonized by mycelium, as this is when it is most vulnerable to the pest.
Linkages Between Malaysian Housing Prices, Property Companies and Stocks

Abstract Although the relationships between house prices, property companies and stocks have received considerable attention in developed markets, little study has been undertaken in emerging markets. Therefore this study aims to investigate the linkages between the Malaysian housing market, property companies and stocks by using a vector-autoregressive model (VAR) over the study period 1999–2009. The results reveal a uni-directional relationship between housing prices, property companies and stocks. Specifically, property companies and general stocks Granger cause the housing market, whereas there is no evidence to support that property companies and stocks will incorporate the information spillover from the housing market. These findings offered some insights into the dynamic behaviour of housing prices, particularly in a developing country context.
Frogs and salamanders from the Upper Jurassic Morrison Formation (Quarry Nine, Como Bluff) of North America

ABSTRACT Previously undescribed frog and salamander bones from the Morrison Formation, at Quarry Nine, Como Bluff, Wyoming, are reported. One anuran ilium is diagnostically discoglossid and forms the basis of Enneabatrachus hechti, gen. et sp. nov. A second ilium is diagnostically pelobatid and is the earliest record for the family Pelobatidae, although it is indeterminate below family level. Salamander vertebrae appear to represent two morphological types but neither can be diagnosed critically. The previously described anuran taxa Eobatrachus agilis Marsh and Comobatrachus aenigmatis Hecht and Estes and the salamander Comonecturoides marshi Hecht and Estes are all based on non-determinate elements and must be considered nomina dubia at our present state of knowledge.

Reproductive Images: The Autonomous Cell

New medical imaging technologies enable the production of photos of human cells that are magnified to make them visible to the eye. Such cellular images have gained aesthetic as well as dramatic appeal, as they have moved out of the laboratories and become available for the public. At this stage, they are refashioned to reveal matters more clearly and pedagogically. Organic matter that might be confusing to the audience is removed and colours added to distinguish various aspects—but despite such manipulations, the result appears as images of real human cells, making them different from drawings and models. One example of this is the website of a Norwegian governmental organization for information on biotechnology and bioethics which displays images of egg and sperm cells related to techniques of assisted reproduction. These images represent cells as autonomous and independent of human gendered bodies. The process whereby cells culturally become detached and disassociated from human bodies is here referred to as a process of entification whereby the cells reappear as detachable, usable entities.
CLOTTING PROCESSES IN CRUSTACEA DECAPODA

1. In Limulidae, all the factors involved in the coagulation processes are located inside the amoebocytes. The cellular coagulogen is a single 20,000‐polypeptide‐chain protein. It is converted into a non‐covalently crosslinked gel by a serine protease enzyme which cleaves a single peptide bond, releasing peptice C.
Real-time PCR detection and quantification of Fusarium poae, F. graminearum, F. sporotrichioides and F. langsethiae in cereal grains in Finland and Russia

Abstract TaqMan real-time quantitative PCR assays were developed for the accurate detection and quantification of DNA from Fusarium poae and F. graminearum species, which are able to produce trichothecenes. These and other PCR assays were used for the quantification of trichothecene-producing Fusarium fungi in cereal grains. A correlation was found between the levels of F. poae DNA and nivalenol and enniatins in barley and between the levels of F. graminearum DNA and deoxynivalenol in oats. The correlations between F. poae DNA and nivalenol and F. graminearum DNA and deoxynivalenol levels were higher than those between these mycotoxins and morphologically determined F. poae and F. graminearum/F. culmorum contamination levels. The use of F. poae specific primers and probe together with F. sporotrichioides/F. langsethiae specific primers and probe in a multiplex qPCR assay yielded results in accordance with those obtained using these primers and probes separately.
Structure-activity relationship of brassinosteroids with respect to the A/B-ring functional groups

In order to examine the biological role of the A/B-ring functional groups of plant-growth-promoting brassinosteroids, twenty-three brassinosteroids with some modifications at rings A and B (1-15 and 22-29) were bioassayed by means of the rice-lamina inclination test. The results showed that 1) removal of one or two hydroxyl groups from the A-ring reduced the biological activity of the steroids; 2) the 7-oxalactone brassinosteroids were almost as active as the corresponding 6-oxo steroids and they were much more active than their regioisomeric 6-oxalactone counterparts; 3) introduction of a double bond at the C-7 position and a hydroxyl group at the C-5 position of 6-oxo brassinosteroids significantly decreased the biological activity of the hormonal steroids. These data suggest that the presence of a 2α, 3α-diol, 7-oxalactone or 6-oxo group, and the A/B-trans ring junction are important for high biological activity.
Effects of hydrogen cyanamide, paclobutrazol and pruning date on dormancy release of the low chill peach cultivar Flordaprince in subtropical Australia

The growth regulator hydrogen cyanamide (Dormex, 50% a.i.) was tested for its effectiveness in promoting earlier and more even budbreak, flowering, and fruit maturity of the low chill peach cv. Flordaprince at 2 sites in subtropical Australia. The influence of the growth retardant paclobutrazol was also tested at 1 site, and at the other, the effect of altering pruning date. At 1 site only, hydrogen cyanamide applied early-mid June, during endodormancy, advanced mean harvest time by 10 days. At the other site, there were no consistent trends between harvest time and date of application of cyanamide. Dormex at the lowest concentration applied (10 mL/L) caused severe yield reductions (40.8%). Flowering and fruit maturity were advanced by about 6 days with dormant pruning in early winter, compared with pruning at later dates, and by 13 days with the application of the growth retardant paclobutrazol, compared with no application.
