Abusive Supervision, Emotion Regulation, and Performance

This study examined the abusive supervision’s influence on emotion regulation and outcomes. Based on COR theory, we investigated whether supervisor abuse has a direct relationship with the emotional labor strategies of surface acting (monitoring external emotions) and deep acting (monitoring internal feelings). In turn, we investigated the indirect relationship of supervisor abuse on outcomes (i.e., emotional exhaustion, job satisfaction, and task performance) via these emotional labor strategies. Using lagged and dyadic sample (210 subordinates and 30 supervisors), we found that abusive supervision predicted surface and deep acting and that the indirect associations of supervisor abuse on outcomes via emotional labor strategies were also significant. The present investigation empirically supports the theorized links and offers notable implications for personnel selection and assessment.
Evaluation of Light Gradient Boosted Machine Learning Technique in Large Scale Land Use and Land Cover Classification

The ability to rapidly produce accurate land use and land cover maps regularly and consistently has been a growing initiative as they have increasingly become an important tool in the efforts to evaluate, monitor, and conserve Earth’s natural resources. Algorithms for supervised classification of satellite images constitute a necessary tool for the building of these maps and they have made it possible to establish remote sensing as the most reliable means of map generation. In this paper, we compare three machine learning techniques: Random Forest, Support Vector Machines, and Light Gradient Boosted Machine, using a 70/30 training/testing evaluation model. Our research evaluates the accuracy of Light Gradient Boosted Machine models against the more classic and trusted Random Forest and Support Vector Machines when it comes to classifying land use and land cover over large geographic areas. We found that the Light Gradient Booted model is marginally more accurate with a 0.01 and 0.059 increase in the overall accuracy compared to Support Vector and Random Forests, respectively, but also performed around 25% quicker on average.
DIAGNOSTIC STUDY ON MICROFILARIAE AND SOME BLOOD PROTOZOA IN QUAIL BIRDS (COTURNIX COTURNIX JAPONICA) IN NINEVEH GOVERNORATE

The study covered a diagnosis for detection of microfliaria in 90 blood samples obtained from quail birds. The results recorded that total infestion rate was (15.6%). Three species of microfliaria have been diagnosed in quail. Form A of detected larvae measured 106 – 125 µm in length and 2.5 –3.0 µm in width, while form B measured 97–145.4 µm in length and 4.0 – 6.0 µm in width , finally form C dimensions measured 120–150 µm and 4.5 – 5.0 µm in width respectively. Knott technique detected most positive cases with higher sensitivity rate 85.7%, than other techniques used in the study. The rate of infection recorded in adult birds 14.5% was little higher than it in young birds 10.7% with no significant statitiscal defferences between males and females. The study showed appearance of 7.7% of mixed infections of microfliaria with Aegyptianella spp. and 4.4% with plasmodium spp. Finally the study pointed that microfliaria appeared with high percentage in circulating blood than peripheral blood of 40 quail birds, as15% and 10%in circulating and peripheral blood respectively.
Optimal perturbations in viscous round jets subject to Kelvin–Helmholtz instability

Abstract We investigate the development of three-dimensional instabilities on a time-dependent round jet undergoing the axisymmetric Kelvin–Helmholtz (KH) instability. A non-modal linear stability analysis of the resulting unsteady roll-up into a vortex ring is performed based on a direct-adjoint approach. Varying the azimuthal wavenumber $m$, the Reynolds number ${Re}$ and the aspect ratio $\alpha$ of the jet base flow, we explore the potential for secondary energy growth beyond the initial phase when the base flow is still quasi-parallel and universal shear-induced transient growth occurs. For ${Re}=1000$ and $\alpha = 10$, the helical $m=1$ and double-helix $m=2$ perturbations stand as global optimals with larger growth rates in the post roll-up phase. The secondary energy growth stems from the development of elliptical (E-type) and hyperbolic (H-type) instabilities. For $m>2$, the maximum of the kinetic energy of the optimal perturbation moves from the large scale vortex core towards the thin vorticity braid. With a Reynolds number one order of magnitude larger, the kinetic energy of the optimal perturbations exhibits sustained growth well after the saturation time of the base flow KH wave and the underlying length scale selection favours higher azimuthal wavenumbers associated with H-type instability in the less diffused vorticity braid. Doubling the jet aspect ratio yields initially thinner shear layers only slightly affected by axisymmetry. The resulting unsteady base flow loses scale selectivity and is prone to a common path of initial transient growth followed by the optimal secondary growth of a wide range of wavenumbers. Increasing both the aspect ratio and the Reynolds number thus yields an even larger secondary growth and a lower wavenumber selectivity. At a lower aspect ratio of $\alpha =5$, the base flow is smooth and a genuine round jet affected by the axisymmetry condition. The axisymmetric modal perturbation of the base flow parallel jet only weakly affects the first common phase of transient growth and the optimal helical perturbation $m=1$ dominates with energy gains considerably larger than those of larger azimuthal wavenumbers whatever the horizon time.
Multifractal and joint multifractal analysis of soil micronutrients extracted by two methods along a transect in a coarse textured soil

Understanding the spatial behaviour of soil nutrients is essential for fertilizer management. Traditionally, comparison of soil testing methods has been performed using simple correlation analysis. The aims of this work were: (a) to characterize patterns of spatial variability of micronutrient concentrations obtained by two different soil testing methods, using single multifractal spectra, and (b) to compare the scale‐dependent relationship between the two datasets by joint multifractal analysis. The soil study site was located in Pernambuco state, Brazil. A 384‐m transect was marked every 3 m on an Orthic Podzol, cropped to sugar cane, in Pernambuco state, Brazil. Both, Mehlich‐3 and DTPA‐extracted micronutrients were measured in each of the 132 collected soil samples. The spatial distributions of available Fe, Mn, Cu and Zn could be fitted with multifractal models, regardless of the soil testing method. The generalized dimension, Dq versus q, and singularity spectra, f(α) versus α, showed a multifractal nature. Except for Fe, the scaling heterogeneity of the spatial distributions was higher for the Mehlich‐3 than for the DTPA datasets. Moreover, Zn exhibited the highest multifractality in both cases. Joint multifractal analysis demonstrated strong positive correlations between the scaling indices of the studied micronutrients extracted by the two methods. There were, however, different degrees of association between the scaling indices of these micronutrients, which ranked as: Zn > Cu > Fe > Mn. Except for Mn, Pearson product moment correlations between concentrations of available micronutrients extracted by the two solutions at the single or point measurement scale were weaker than those of the respective scaling indices at multiple scales. Therefore, single multifractal analysis captured a great complexity in the spatial distribution of available Fe, Mn, Cu and Zn. Knowledge of the scaling behaviour of these available nutrients could be useful for transferring information about variability from one scale to another for soil fertility management. This study suggests that correlation analysis at the single or point measurement scale may not be sufficient to fully characterize the concentrations of microelements extracted by two different methods, whereas joint multifractal analysis showed potential to improve calibration of soil micronutrient testing.
Hygienic Quality Assessment Of Pork Carcasses Obtained In Industrial And Traditional Slaughtering Units

In March 2016, the microbiology laboratory of the Faculty of Veterinary Medicine Cluj-Napoca, 3 type of antiDespite the fact that many types of foods can be sources of food borne illnesses, meat and meat products are very important sources of infection in people with a wide variety of pathogens that cause food poisoning. The aim of this study was to conduct an assessment of meat hygienic quality and configuration by assessing the microbial load and the presence of pathogens. The material under investigation was represented by 40 samples of muscle tissue from pork carcasses collected in stages, between 2015-2016, from slaughtering units both from the traditional system and the industrial system. Samples were analyzed at the Department of Food Safety and Control of Animal Origin Products. Total viable count in samples taken from the carcasses, in 2016 presented values similar to those in 2015, ranging from a minimum of 2.74 ± 0.36 log cfu/cm2 in January and December and a maximum 3.73 ± 1.13 log cfu / cm2 recorded in February, without showing significant differences between the samples processed in the studied period (p>0.05). The results regarding contamination of swine carcasses (surface) with germs from Enterobacteriaceae family were non-compliant, exceeding the maximum permissible limit of 3.0 log cfu/cm2 in all 12 samples examined (30%). In what regards the molecular testing for the confirmation of E. coli, a total of 6 samples were positive, but none of this tested positive for the presence of the toxicity genes (Stx1, Stx2). In the case of the samples taken from pork carcasses the results regarding germs from Enterobacteriaceae family were non-compliant, 29.16% of the samples examined during the period under study were found to exceed the maximum limit, which showed deficiencies regarding the hygiene requirements.
An assessment of the role of proper health management in reducing goat mortality in Kraals: A case of Napak District in Eastern Uganda

Poor animal health is reported as one of the major constraints of goat production leading to mortality in pastoral areas like Karamoja Sub-Region in Eastern Uganda. Based in Napak District, this study was aimed at gaining an understanding of the role of proper health management in reducing goat mortality in Kraals. Through convenience sampling, 312 pastoralists out of 388 who own animals in community kraals were reached. The study was carried out using mixed methods approach through structured interviews and focus group discussions to collect both primary and secondary data. The health management index (HMI) as a measure of proper goat health management was constructed using seven routine farm practices (Vaccination, Deworming, Use of Antibiotic, Spraying, Isolation of sick animals, Sanitation and Hygiene and Navel Cord Disinfection). Multivariable regression was conducted using STATA (12) software. The first regression was conducted to find out which socio-economic factors have influence on HMI. It was established that accessibility to training and membership to social groups improve HMP while involvement in other occupation has a negative influence. A second regression was conducted to ascertain if HMI scores affect goat mortality levels. The results revealed a negative and significant influence, implying that an improvement in HMP leads to a reduction in mortality. Enhancing mechanisms which favor practical training and social group formation in form of technology intervention platforms can enhance HMP which will ultimately reduce goat mortality. Key words: Socio-economic factors, goat health management index, Karamoja, goat, multivariable regression.
Relative effectiveness of trapping and hand-capture for controlling invasive cane toads (Rhinella marina)

ABSTRACT Management of invasive vertebrates is a crucial component of conservation. Management strategies should increase the chance of removal of every individual, by exploiting behavioural characteristics, and by increasing the period over which removal occurs. For example, traps can operate automatically over long periods, and often include attractants to increase captures. Management strategies for the invasive cane toad (Rhinella marina) in Australia include hand capture and trapping adult individuals (toads are attracted to an acoustic lure, and to insects attracted to a light, also on the lure). We used capture-mark-recapture analysis to compare the efficacy of trapping and hand capturing cane toads over 10 weeks, in Townsville, Australia. We trapped 7.1%–22.4% of the estimated population per week, and hand captured 1.7%–6% of the estimated population per week. Trapping was more efficient than hand capture in our regime; overall, more toads were caught per trapping man-hour than per hand-capture hour. Traps attract toads and maximise the period over which removal occurs; thus, the probability of removal for each toad was higher than by hand capture. Because hand capture and trapping seemed to remove different toads, a combination of these methods may work well.
Evaluation of D-dimer concentrations in clinically ill dogs with high risk of thromboembolic disease.

Received: Revised: Accepted: Published online: March 18, 2015 January 06, 2016 February 07, 2016 March 18, 2016 Many systemic and metabolic diseases are associated with increased risk factors that promote the development of thrombus. But early diagnosis of thromboembolism (TE) may difficult in general practice due to a lack of noninvasive diagnostic tests. This study was conducted to compare the plasma concentration of D-dimer, platelet numbers and fibrinogen degradation products (FDPs) between healthy and clinically ill dogs to evaluate the usefulness of these assays in detections of hypercoagulability. Eighty-one clinically ill dogs with high risk of TE and 25 healthy dogs were included in this study. The plasma D-dimer concentrations were measured through the immunometric assay, and FDPs concentration was measured by semi-quantitative latex agglutination assay. Results of the present study indicated D-dimer concentrations were mainly elevated in immune-mediated hemolytic anemia (IMHA), liver disease, neoplasia and miscellaneous inflammatory disease group. In addition, markedly increased Ddimer concentrations (>2000ng/ml) were also mostly presented in IMHA (33.3%), liver disease (20%), and neoplasia (14.3%) group. Platelet numbers were significantly different only in neoplasia and endocrine disorder group. The plasma concentrations of D-dimer and FDPs of clinically ill dogs were mainly increased compared to healthy dogs. However, almost 30% of dogs with normal D-dimer value showed positive FDP assay results in both healthy and disease group. Concurrently performed plasma D-dimer and FDPs assays can be rapid screening tests for hypercoagulability in canine patients; however, cautious interpretation is required and should not be used as single diagnostic tool for TE. ©2016 PVJ.

Planting dates and yields of four sweet potato clones in Puerto Rico

Four clones of sweet potato were planted in lsabela, Puerto Rico, each month in 1984, and after 4 months 6 measurements of yield were taken (number, weight/root, total weight of commercial sized roots, and total roots). Clones differed significantly with respect to all measurements, and significant differences were also found among months for all measurements. There were significant interactions between month and clone with respect to 4 of the 6 measurements. The 6 measurements were distributed over months bimodally for 2, and irregularly for 4 measurements. The measurements were not related to months by regression analysis, Differences among the 4 clones may be due to different responses to daylength, rainfall, temperature, and light intensity. It was concluded that sweet potato clones differ with respect to response to planting dates, and each clone merits separate evaluation.
Formation and control of the E2∗ center in implanted β-Ga 2O 3 by reverse-bias and zero-bias annealing

Deep-level transient spectroscopy measurements are conducted on β-Ga 2O 3 thin-films implanted with helium and hydrogen (H) to study the formation of the defect level E2∗ ( EA = 0.71 eV) during heat treatments under an applied reverse-bias voltage (reverse-bias annealing). The formation of E2∗ during reverse-bias annealing is a thermally-activated process exhibiting an activation energy of around 1.0 eV to 1.3 eV, and applying larger reverse-bias voltages during the heat treatment results in a larger concentration of E2∗. In contrast, heat treatments without an applied reverse-bias voltage (zero-bias annealing) can be used to decrease the E2∗ concentration. The removal of E2∗ is more pronounced if zero-bias anneals are performed in the presence of H. A scenario for the formation of E2∗ is proposed, where the main effect of reverse-bias annealing is an effective change in the Fermi-level position within the space-charge region, and where E2∗ is related to a defect complex involving intrinsic defects that exhibits several different configurations whose relative formation energies depend on the Fermi-level position. One of these configurations gives rise to E2∗, and is more likely to form if the Fermi-level position is further away from the conduction band edge. The defect complex related to E2∗ can become hydrogenated, and the corresponding hydrogenated complex is likely to form when the Fermi level is close to the conduction band edge. Di-vacancy defects formed by oxygen and gallium vacancies (V O−V Ga) fulfill several of these requirements, and are proposed as potential candidates for E2∗.
Positive and negative interactions control a facilitation cascade

Facilitation cascades, which enhance the diversity of ecological communities in many ecosystems, have been viewed as the net outcome of positive species’ interactions. The strength and direction of these interactions, and thus the realized biodiversity, however, are likely to vary with the density and traits of the habitat-formers and via negative interactions among interacting species. To test this, we manipulated the density and status (alive vs. dead) of a secondary habitat-former, the razor clam Pinna sp. , and measured responses by the primary habitat-former, the seagrass Zostera muelleri, associated epifauna and infauna, and fish foraging behavior. At the plot level, for both live and dead clams, the total abundance of epifauna increased with clam density. However, for individual clams, the density of epifauna/cm decreased with increasing clam density. Video image analysis showed higher fish predation of epifauna on dead compared to live clams at high but not low densities and path analysis indicated that these strong negative trophic interactions increased with dead clam density via both direct and indirect pathways. By contrast, an increasing density of live but not dead clams was negatively correlated with seagrass faunal densities. However, seagrass growth and standing biomass were unaffected by clam density or status. Our study illustrates that the realized facilitation cascade is a function of nested negative and positive interactions which change as a function of the density of clams and whether they were dead or alive, and therefore do not represent a collection of hierarchical positive interactions.
Analysis of Population Genomic Data from Hybrid Zones

Hybrid zones provide a powerful opportunity to analyze ecological and evolutionary interactions between divergent lineages. As such, research on hybrid zones has played a prominent role in the fields of evolutionary biology and systematics. Herein, we clarify what hybrid zones are, what is (and is not) known about them, and how different types of genomic data contribute to our understanding of hybrid zones. We then review two key topics, namely, what genomic analyses of hybrid zones have revealed about the basis and dynamics of speciation and how hybrid zones directly affect evolutionary processes. In the latter case, we emphasize the importance of contingency and ecological and genomic context in outcomes of hybridization. Throughout, we highlight limitations and key unknowns, and suggest approaches most likely to advance our understanding of hybrid zones and evolutionary processes in general.
Composition and colour indices of sheep’s bulk-tank milk are influenced by production practices

Abstract Over the past few years, there has been a great development of the sheep dairy sector in Spain and a wide variability in the production outcomes of farms, although most of the farms have similar environmental and economic constraints. Milk quality evaluation is important not only for cheese production, but also for other dairy products. Therefore, the aim was to evaluate the effect of some factors on bulk-tank milk characteristics of Manchega sheep, with special attention to casein and urea contents and colour indices. Factors of variation such as season, annual milk yield of ewe (AMYE), the enrolment (or not) in a breeding programme (BPM) and the feeding strategy of farms have been considered. The study included 77 farms distributed along La Mancha region, in Spain. Data about production practices and feeding strategy were also collected from these farms. A total of 308 analytical determinations of milk characteristics including fat, protein, total solids, casein, lactose, protein/total solids, casein/fat, pH, urea content, colour indices and somatic cell count were analysed by automated methods. The results of the present work indicate that season was the source of variation with the greatest effect on chemical characteristics of bulk-tank milk, except for casein/fat ratio for which the difference was smaller. The feeding strategy effects on characteristics of milk have also been confirmed Moreover, it has been demonstrated that the feeding strategies are applied more coherently according to their productive characteristics in farms with small and medium size than in farms with the largest herd size.
Mechanical activation of epithelial Na+ channel relies on an interdependent activity of the extracellular matrix and extracellular N-glycans of αENaC

Mechanotransduction describes how cells perceive their mechanical environment and mechanosensitive ion channels are important for this process. ENaC (epithelial Na+ channel)/DEG (degenerin) proteins form mechanosensitive ion channels and it is hypothesized their interaction with the extracellular matrix (ECM) via ‘tethers’ is required for mechanotransduction. Channels formed by vertebrate α, β and γ ENaC proteins are activated by shear force (SF) and mediate electrolyte/fluid-homeostasis and blood pressure regulation. Here, we report an interdependent activity of ENaC and the ECM that mediates SF effects in murine arteries and heterologously expressed channels. Furthermore, replacement of conserved extracellular N-glycosylated asparagines of αENaC decreased the SF response indicating that the attached N-glycans provide a connection to the ECM. Insertion of N-glycosylation sites into a channel subunit, innately lacking these motifs, increased its SF response. These experiments confirm an interdependent channel/ECM activity of mechanosensitive ENaC channel and highlight the role of channel N-glycans as new constituents for the translation of mechanical force into cellular signals.
