Behavioural activity of wild rabbits (Oryctolagus cuniculus) under semi-natural rearing systems: establishing a seasonal pattern

The activity of 2 populations of wild rabbits (Oryctolagus cuniculus, L. 1758), consisting of 14 adults (>9 mo of age) each (4 males and 10 females), was analysed over 2 consecutive years. Rabbits were captured in the wild and kept in 2 separate enclosures of 0.5 ha, with each enclosure divided into 2 zones: a smaller area where warrens were located (breeding area) and a larger area where food and water were provided (feeding area). Seven rabbits in each enclosure were individually tagged with a microchip (2 males and 5 females) and, after installing 2 detection devices, it was possible to identify which of the 2 areas they were located in and record the length of time spent in each. To regulate the size of the breeding population, young rabbits produced in the enclosures were captured and removed regularly. Considering the number of movements between areas and the time spent in the feeding area, a circadian activity pattern was found, reporting 2 maximum activity peaks coinciding with twilight (18.35% of the total movements, 6-8 a.m.) and daybreak (22.95%, 7-10 p.m.) while activity was dramatically decreased during the midday hours (1.86%, 10 a.m.-4 p.m.). Rabbits displayed a seasonal pattern throughout the year, with maximum activity levels during winter (45.76% of the total movements, January-March) and spring (42.91%, April-June), which could be related to higher reproductive activity at this time of the year as a higher breeding output was reported in June and September. The levels of activity exhibited by males (13.44% daily activity rate) were significantly higher than those displayed by females (9.80%). No significant differences were found regarding time spent on the feeding area in relation to season or gender. The average duration of each foray to the feeding area was higher during the summer, higher for females than males and higher during the middle of the night than the rest of the day.
Aid and Sectoral Growth: Evidence from Panel Data

Abstract This article examines empirically the proposition that aid to poor countries is detrimental for external competitiveness, giving rise to Dutch disease type effects. At the aggregate level, aid is found to have a positive effect on growth. A sectoral decomposition shows that the effect is (i) significant and positive in the tradable and the nontradable sectors, and (ii) equally strong in both sectors. The article thus provides no empirical support for the hypothesis that aid reduces external competitiveness in developing countries. A possible reason for this finding is the existence of large idle labour capacity that prevents the real exchange rate from appreciating.
AN EFFICIENT PERSONALIZED HOTEL RECOMMENDATION SYSTEM FOR BIG DATA APPLICATIONS

Administration recommender frameworks have been indicated as important apparatuses for giving proper proposals to clients. In the most recent decade, the measure of clients, administrations and online data has developed quickly, yielding the enormous information examination issue for administration recommender frameworks. Also the greater part of existing administration recommender frameworks, exhibit the same appraisals and rankings of administrations to distinctive clients without considering various clients' inclination, and hence neglects to meet clients' customized necessities. Consequently we approach a customized administration proposal rundown for the most suitable administrations to clients, by proposing a keyword-aware suggestion strategy and Natural Language Processing, to address the above difficulties. Particularly, keywords are utilized to demonstrate clients' inclination, and a client based Collaborative Filtering calculation is received to create proper suggestions. To enhance its versatility and productivity in vast information environment, it is actualized on Hadoop platform, a generally embraced appropriated figuring stage utilizing the Map Reduce parallel transforming framework. At long last, far reaching trials are directed on certifiable information datasets, and results exhibit that personalized search technique fundamentally enhances the exactness and versatility of administration recommender frameworks over existing methodologies. Key words: Recommender System, Preference, Keyword, Big Data, Map Reduce, Hadoop, Hotels.
Probability distribution of the free energy of the continuum directed random polymer in 1 + 1 dimensions

We consider the solution of the stochastic heat equation $$\partial_T {\cal Z} = {{1}\over{2}} \partial_X^2 {\cal Z} - {\cal Z} \dot{\cal{W}}$$ with delta function initial condition $${\cal Z} (T=0,X)= \delta_{X=0}$$ whose logarithm, with appropriate normalization, is the free energy of the continuum directed polymer, or the Hopf‐Cole solution of the Kardar‐Parisi‐Zhang equation with narrow wedge initial conditions.
The Antecedents and Outcomes of the Internet of Things Use in Food Firms: The Moderating Role of Firm Size

This study examines the antecedents and outcomes of the use of Internet of Things (IoT) in firms and the moderating role of firm size. Drawing on institutional theory, Corporate Social Responsibility (CSR) and IoT use in firms, we propose a model that is empirically tested by survey data from 352 enabled food firms in Heilongjiang provice. The results show that institutional theory factors and corporate social responsibility determine firms’ IoT use behavior. The results further indicate that IoT use positively infuences firms’ quality and operational performance. The moderating effect of firm size on the relationship between IoT use and operational performance is negative, indicating that IoT can play a more positive role on opertation management in small firms. These findings contribute to the literature on IoT in food safety and are the basis for recommendations for advancing IoT.

Computer simulations of the effects of the Sitka eddy on the migration of sockeye salmon returning to British Columbia

The Sitka eddy is a mesoscale eddy, 300 km in diameter, that develops off SE Alaska in about one year in two 2 . The eddy has surface currents exceeding 50 km day )1 and it has been suggested that the eddy could deflect migrating salmon to the south, thereby reducing the proportion of British Columbia (BC) sockeye salmon accessible to Alaskan fishers. We modelled its effects on the migration of sockeye salmon (Oncorhynchus nerka) returning to northern BC, using an individual-based model to simulate migration paths, migration timing and metabolic costs of salmon with different migration behaviours. Except when their migration behaviour included positive rheotaxis, salmon that encountered the eddy had faster migration times and lower metabolic costs than those that did not. The least complex migration behaviour, compass orientation with no rheotaxis, was only slightly less efficient in metabolic terms than the optimal migration paths determined by dynamic programming. Our simulations show that the Sitka eddy itself does not deflect migrating salmon to the south or south-east regardless of migration behaviour, but that by interrupting the normal northward flow of the
Astrometric search for a planet around VB 10

We observed VB 10 in August and September 2009 using the FORS2 camera of the VLT with the aim of measuring its astrometric motion and of probing for the presence of the announced planet VB 10b. We used the published STEPS astrometric positions of VB 10 over a timespan of 9 years, which allowed us to compare the expected motion of VB 10 due to parallax and proper motion with the observed motion and to compute precise deviations. The single-epoch precisions of our observations are about 0.1 mas, and the data showed no significant residual trend, while the presence of the planet should have induced an apparent proper motion greater than 10 mas yr -1 . Subtraction of the predicted orbital motion from the observed data produces a strong trend in position residuals of VB 10. We estimated the probability that this trend is caused by random noise. After taking all the uncertainties into account and using Monte-Carlo resampling of the data, we are able to reject the existence of VB 10b with the announced mass of 6.4 M J with a false alarm probability of only 5 × 10 -4 . A 3.2 M J planet is also rejected with a false alarm probability of 0.023.
LANDSCAPING REACTION KINETICS ON A CHIP

We report on a highly integrated microfluidic platform with parallel processes for metering, concentration gradient generation, mixing, and optical detection on a single chip. The characteristics of this automated microfluidic system are not only accurate and for rapid analysis of enzyme reaction kinetics according to the nano/picoliters of reagents, but also provide a spontaneous and vivid three-dimensional output, which provides many advantages, including significant reduction in sample consumption, and greater sensitivity for the biomedical and pharmaceutical applications.
Electron microscopy of frozen water and aqueous solutions

Thin layers of pure water or aqueous solutions are frozen in the vitreous state or with the water phase in the form of hexagonal or cubic crystals, either by using a spray‐freezing method or by spreading the liquid on alkylamine treated films. The specimens are observed in a conventional and in a scanning transmission electron microscope at temperatures down to 25 K. In general, the formation of crystals and segregation of solutes during freezing, devitrification and evaporation upon warming, take place as foreseen by previous X‐ray, thermal, optical and electron microscopical studies. Electron beam damage appears in three forms. The devitrification of vitreous ice. The slow loss of material for the specimen at a rate of about one molecule of pure water for every sixty electrons. The bubbling in solutions of organic material for doses in the range of thousands of e nm−2. We propose a possible model for the mechanism of beam damage in aqueous solutions.
Bank Capital, Performance and Regulation: Some International Evidence

This study addresses the issues of the determinants of bank financial performance and deregulation’s effect on performance. This study is based on Bank Scope data covering 464 commercial banks from the U.S., Japan and eleven EU countries for the years 1989-1995. There are a total of 3248 observations in our data set. Our results indicate that a strong positive relationship exists between the equity to total assets ratio and performance, confirming findings by Berger (1995). The results on the regulatory variables are mixed, with no clear pattern emerging across countries. Often these differences in regulations are associated with statistically significant effects on performance, but the direction of the effects change depending on which measure of performance is used.
LEARNING ORIENTATION AND TRUST IN SMALL AND MEDIUM ENTERPRISE (SME) EXPORT COMPETITIVE ADVANTAGE

Trust in inter-organisational relationships is becoming an increasingly important topic in international business studies. Trusting relationships are even more important to small businesses with limited operational resources, which makes partnerships with foreign importers an important strategic consideration. When exporters pursue these endeavours, they are able to leverage partner company competencies. Organisations gain market knowledge and, thereafter, a greater export competitive advantage. This study examines the antecedents of relationships between small and medium export and import enterprises. This study also investigates the effects of Small and Medium Enterprise (SME) relationships on exporters’ competitive advantage. Based on a sample of 228 SMEs, trust positively and significantly affects competitive advantage. In addition, managerial commitment is crucial for SMEs pursuing trusting and beneficial relationships with foreign importers. We conclude this paper with a statement of limitations and recommendations for future research.

The paper describes some of the key stakeholders involved in the redevelopment and planning of the site. It provides an overview of the regulatory context and governance bodies that have structured the space since the staging of the Olympics, then identifies two key areas of private-sector involvement, in event space and in business development, where tensions emerged over how the site should best be governed.
Healthcare Expenditure, Economic Growth, and Inflation in the G7 Countries: A Panel Cointegration Approach

The main aim of this research article is to explain the relationship between the healthcare expenditure, economic growth and inflation in a panel data of the G7 countries for the period 1995 to 2013 by using panel co-integration analysis. To explore the effect of inflation on healthcare expenditure, this article constructs two individual models using the consumer price index (CPI) inflation in the first, and the personal consumption expenditure price index (PCE) in the second. The CPI inflation has been used to calculate the change in the out-of-pocket expenditure of all urban households, while, the PCE inflation was used to measure spending on behalf of households. The results show that the CPI inflation has the most effect on healthcare expenditure rather than the PCE inflation. Also, healthcare expenditure is a necessary good as the short-run income elasticity is less than one for both two models. Using vector error correction model (VECM), the econometric results showed that there is a strong short-run Granger causality from economic growth and price index to healthcare expenditure in both models. Moreover, the impulse response function (IRF) analysis showed that there is a strong positive bidirectional long-run Granger causality between healthcare expenditure and economic growth, and a strong negative bidirectional long-run Granger causality between healthcare expenditure and inflation in both models.
Assessing the response of degradative biofilms to groundwater pollutants

There is limited knowledge of interspecies interactions in biofilm communities. In this study, Pseudomonas sp. GJ1, a 2-chloroethanol (2-CE) degrading organism, and Pseudomonas putida DMP1, a p-cresol degrader, produced distinct biofilms in response to model mixed waste streams comprised of 2-CE and various p-cresol concentrations. The two organisms maintained a commensal relationship, with DMP1 mitigating the inhibitory effects of p-cresol on GJ1. A triple labeling technique compatible with confocal microscopy was used to investigate the influence of toxicant concentrations on biofilm morphology, species distribution, and exopolysaccharide production. Single species biofilms of GJ1 shifted from loosely associated cell clusters connected by exopolysaccharide to densely-packed structures as p-cresol concentrations increased, and biofilm formation was severely inhibited at high p-cresol concentrations. In contrast, GJ1 was abundant when associated with DMP1 in a dual species biofilm at all p-cresol concentrations, although at high p-cresol concentrations it was only present in regions of the biofilm where it was surrounded by DMP1. Evidence in support of a commensal relationship between DMP1 and GJ1 was obtained by comparing GJ1-DMP1 biofilms with dual species biofilms containing GJ1 and Escherichia coli 33456, an adhesive strain that does not mineralize p-cresol. Additionally, the data indicated that only tower-like cell structures in the GJ1-DMP1 biofilm produced exopolysaccharide, in contrast to the uniform distribution of EPS in the single-species GJ1 biofilm.
Rhodanese and Mercaptopyruvate Sulphure Transferase Enzymes in the Tissues of Chichilidae ( Tilapia Zillii , Sarotherodon Galilaeus ) and Hepsetidae ( Hepsetus Odoe ) in Igun River , Ilesa , Southwestern Nigeria

The cyanide detoxifying enzymes (rhodanese and mercaptopyruvate sulphurtransferase [MST]) were estimated in different tissues of three fishes (Tilapia zillii, Hepstus odea and Sarothodelon galileaus) from Igun River in Ilesa, South-Western region of Nigeria. The enzyme activities were carried out by measuring the amount of thiocyanate produced by the two enzymes using specific substrates in each case. The results also showed that both enzymes have a statistically high specific activity in Hepstus odea in all the tissues, followed by Sarothodelon galileaus and Tilapia zillii. Moreover, the tissue with the highest protein concentration is the gut, then the gills and the flesh, although the differences in their protein concentrations were statistically insignificant. The gut also showed the highest MST specific activity statistically, afterwards the gills and the flesh. Conversely, the rhodanese specific activity was however revealed to be high in the flesh than other tissues, but not statistically significantly different from the other tissues. The study showed the activities of two cyanide detoxifying enzymes (rhodanese and mercaptopyruvate sulphurtransferase) in the different fishes indicating the existence of a strong cyanide detoxifying mechanisms
Impact of a program of diagnostic imaging quality control in mammography centers of the Federal District , Brazil *

OBJECTIVE: The present study was aimed at evaluating the quality and the impact of an intervention involving inspection and education in mammography centers of the Federal District, Brazil. MATERIALS AND METHODS: Forty one mammography centers in the Federal District were studied in the period between 2000 and 2002. The intervention involved an initial inspection followed by a training activity and notification of mammography centers by the Federal District Sanitary Vigilance authority. The imaging quality was compared before and after the intervention. RESULTS: None of the 36 centers which completed the study reached more than 90% compliance with the standard imaging quality prior to the interventions, whereas ten were above 90% afterwards. Major improvements were observed in chassis maintenance, breast compression and visualization of microcalcifications. CONCLUSION: Despite the availability of a great number of mammography centers in the Federal District, most of them did not meet the required quality standards. The intervention has shown to be effective for improving the imaging quality, however a continued action is required to solve the remaining problems and increase the impact of the program.
Ake: An R Package for Discrete and Continuous Associated Kernel Estimations

Kernel estimation is an important technique in exploratory data analysis. Its utility relies on its ease of interpretation, especially based on graphical means. The Ake package is introduced for univariate density or probability mass function estimation and also for continuous and discrete regression functions using associated kernel estimators. These associated kernels have been proposed due to their specific features of variables of interest. The package focuses on associated kernel methods appropriate for continuous (bounded, positive) or discrete (count, categorical) data often found in applied settings. Furthermore, optimal bandwidths are selected by cross-validation for any associated kernel and by Bayesian methods for the binomial kernel. Other Bayesian methods for selecting bandwidths with other associated kernels will complete this package in its future versions; particularly, a Bayesian adaptive method for gamma kernel estimation of density functions is developed. Some practical and theoretical aspects of the normalizing constant in both density and probability mass functions estimations are given.
Reproducibility and repeatability of intracyclic velocity variation in front crawl swimming from manual and semi-automatic measurement

Purpose. Intracyclic velocity variation is an important kinematic parameter to evaluate swimming performance. It can be estimated by a fixed point at the swimmer’s hip. The aim of the study was to determine the reproducibility and repeatability of active light markers to measure intracyclic velocity variation in swimming. Methods. reproducibility and repeatability were tested by image measurement, by five manual digitizing processes and five sessions of automatic tracking of a LED marker set in a swimmer’s hip. The procedures were evaluated by the intraclass correlation coefficient, and the agreement between the methods was evaluated with Bland-Altman plots. The reproducibility was excellent in both procedures. Results. The repeatability of manual digitalization ranged between satisfactory to excellent, while the repeatability of automatic tracking was excellent. In addition, the Bland-Altman plots displayed a good agreement between manual and automatic measurements. The automatic tracking was 27% faster than manual digitization. Conclusions. Active markers are promising to evaluate the intracyclic velocity variation of swimmers, with a faster response than the common manual processing.
Cutting forces and surface roughness in hard turning of hot work steel X38CrMoV5-1 using mixed ceramic

The aim of this work is to evaluate cutting forces and surface roughness in hard turning of hot work steel X38CrMoV5-1 [AISI H11]. This steel is hardened to 50 HRC, machined by a mixed ceramic tool (insert CC650 of chemical composition 70%Al2O3+30%TiC), free from tungsten on Cr-Mo-V ba-sis, insensitive to temperature changes and having a high wear resistance. It is employed for the manufacture of highly stressed diecasting moulds and inserts with high tool life expectancy, plastic moulds subject to high stress and forging dies.The tests of slide-lathing were carried out accord-ing to the method of planning experiments. The results made it possible to study the influence of cutting variables (feed rate, cutting speed and depth of cut) and flank wear (VB) on cutting forces and surface roughness. Mathemati-cal models were established to express the influence de-gree of each cutting regime element on the studied techno-logical parameters. Thus, the ranges of the best cutting conditions adapted, were given.This study confirms that in dry hard turning of this steel and for all cutting conditions tested, the major force is the thrust force and the found roughness criteria are close to those obtained in grinding.
Scattering zippers and their spectral theory

A scattering zipper is a system obtained by concatenation of scattering events with equal even number of incoming and out going channels. The associated scattering zipper operator is the unitary equivalent of Jacobi matrices with matrix entries and generalizes Blatter-Browne and Chalker-Coddington models and CMV matrices. Weyl discs are analyzed and used to prove a bijection between the set of semi-infinite scattering zipper operators and matrix valued probability measures on the unit circle. Sturm-Liouville oscillation theory is developed as a tool to calculate the spectra of finite and periodic scattering zipper operators.
