Learning transfer in Catalan local administrations : variables associated with the workplace

Transfer of training to the workplace is often analysed by different models whose aim is to evaluate the impact of training on organizations (Kirkpatrick, 1959; Le Boterf, 1991 and Pineda, 2003 & Phillips, 2006). In some cases, there are models which are only focused on the evaluation of training transfer as a tool which allows us to get to know the effectiveness of training (Noe & Smith, 1986; Olsen, 1998 & Holton, 2005) and which identifies variables that may act either as facilitators or barriers and can be grouped according to factors concerning learner, training activity design and delivery or workplace environment (Baldwin and Ford, 1988 and Burke and Hutchins, 2007). Ultimately, there are some authors who are merely focused on the analysis of those variables closely related to workplace environment in which new learning is supposed to be applied (Clarke, 2002; Gumuseli & Ergin, 2002; Chiaburu, Van Dam & Hutchins, 2010 & Van den Bossche, Segers & Jansen, 2010). This paper underlines the variables associated with the workplace, formerly appeared in a research which aimed to analyse the factors associated with training transfer in Catalan local Administrations. The development of the research includes a longitudinal analysis of nine studies carried out throughout the 2000-2009 period, as well as further contrasting of results with individual interviews and focus groups with the participation of experts, training managers, participants and managers. The main results enable us to confirm that workplace-related variables exert a huge influence on training transfer, especially those concerning supervisors’ role, availability of resources, learners’ motivation in the workplace and work climate
A search for tt(-) resonances using lepton-plus-jets events in proton-proton collisions at root s = 8 TeV with the ATLAS detector

A search for new particles that decay into top quark pairs is reported. The search is performed with the ATLAS experiment at the LHC using an integrated luminosity of 20.3 fb⁻¹ of proton-proton collision data collected at a centre-of-mass energy of √s = 8 TeV. The lepton-plus-jets final state is used, where the top pair decays to W+bW−b⁻, with one W boson decaying leptonically and the other hadronically. The invariant mass spectrum of top quark pairs is examined for local excesses or deficits that are inconsistent with the Standard Model predictions. No evidence for a top quark pair resonance is found, and 95% confidence-level limits on the production rate are determined for massive states in benchmark models. The upper limits on the cross-section times branching ratio of a narrow Z′ boson decaying to top pairs range from 4.2 pb to 0.03 pb for resonance masses from 0.4 TeV to 3.0 TeV. A narrow leptophobic topcolour Z′ boson with mass below 1.8 TeV is excluded. Upper limits are set on the cross-section times branching ratio for a broad colour-octet resonance with Γ/m = 15% decaying to tt¯. These range from 4.8 pb to 0.03 pb for masses from 0.4 TeV to 3.0 TeV. A Kaluza-Klein excitation of the gluon in a Randall-Sundrum model is excluded for masses below 2.2 TeV.G. Aad ... P. Jackson ...

Search for microscopic black holes in pp collisions at sqrt(s) = 8 TeV

A search for microscopic black holes and string balls is presented, based on a data sample of pp collisions at sqrt(s) = 8 TeV recorded by the CMS experiment at the Large Hadron Collider and corresponding to an integrated luminosity of 12 inverse femtobarns. No excess of events with energetic multiparticle final states, typical of black hole production or of similar new physics processes, is observed. Given the agreement of the observations with the expected standard model background, which is dominated by QCD multijet production, 95% confidence limits are set on the production of semiclassical or quantum black holes, or of string balls, corresponding to the exclusions of masses below 4.3 to 6.2 TeV, depending on model assumptions. In addition, model- independent limits are set on new physics processes resulting in energetic multiparticle final states

Embedding A4 into left–right flavor symmetry: Tribimaximal neutrino mixing and fermion hierarchy

AbstractWe address two fundamental aspects of flavor physics: the mass hierarchy and the large lepton mixing angles. On one side, left–right flavor symmetry realizes the democratic mass matrix patterns and explains why one family is much heavier than the others. On the other side, discrete flavor symmetry such as A4 leads to the observed tribimaximal mixing for the leptons. We show that, by explicitly breaking the left–right flavor symmetry into the diagonal A4, it is possible to explain both the observed charged fermion mass hierarchies and quark and lepton mixing angles. In particular we predict a heavy 3rd family, the tribimaximal mixing for the leptons, and we suggest a possible origin of the Cabibbo and other mixing angles for the quarks
Impact perforation of polymer–metal laminates: Projectile nose shape sensitivity

AbstractRecent research has established that polymer–metal laminates are able to provide enhanced impact perforation resistance compared to monolithic metallic plates of the same mass. A number of mechanisms have been proposed to explain this benefit, including the dissipation of energy within the polymer itself, and the polymer deformation enhancing dissipation within the metallic layer. This understanding of the layer interactions and synergies informs the optimisation of the laminate. However, the effect of the nose shape geometry of the projectile on perforation resistance of a particular laminate configuration has not been established. An optimal laminate configuration for one projectile may be sub-optimal for another. This investigation aims to clarify this nose shape sensitivity for both the quasi-static and impact perforation resistance of light-weight polymer–metal laminates. Bi-layer plates are investigated, with a polyethylene layer positioned on either the impacted or distal face of a thin aluminium alloy substrate. Three contrasting nose shapes are considered: blunt, hemi-spherical and conical. These have been shown to induce distinctly different deformation and fracture modes when impacting monolithic metallic targets. For all projectile nose shapes, placing a polyethylene layer on the impacted (rather than distal) face of the bi-layer plate results in an increase in perforation resistance compared to the bare substrate, by promoting plastic deformation in the metal backing. However, the effectiveness of the polymer in enhancing perforation resistance is sensitive to both the thickness of the polymer layer and the nose shape of the projectile. For a thin polyethylene layer placed on the impacted face, the perforation resistance is greatest for the blunt projectile, followed by the hemi-spherical and conical nose geometries. As the thickness of the polymer facing layer approaches the projectile radius, there is a convergence in both failure mode and perforation energy for all three nose shapes. Bi-layer targets can outperform monolithic metallic targets on an equal mass basis, though this is sensitive to the type of polyethylene used, the polymer layer thickness and the projectile nose shape. The greatest benefit of bi-layer construction (on an equal mass basis) is seen for blunt projectiles, using a polyethylene that maintains a high degree of strain hardening at high strain rates (i.e. UHMWPE), and a polymer thickness just sufficient to switch the failure mode in the metal layer from discing (failure at the projectile perimeter) to tensile failure at the plate centre
Geological respiration of a mountain belt revealed by the trace element rhenium

AbstractOxidation of rock-derived, petrogenic, organic carbon (OCpetro) during weathering of sedimentary rocks is a major source of carbon dioxide (CO2) to the atmosphere. This geological respiration is thought to be enhanced by physical erosion, suggesting that mountain belts could release large amounts of CO2 to counter the CO2 sequestration achieved by the erosion, riverine transfer and oceanic burial of organic carbon from the terrestrial biosphere. However, OCpetro oxidation rates in mountain belts have not been quantified. Here we use rhenium (Re) as a proxy to track OCpetro oxidation in mountain river catchments of Taiwan, where existing measurements of physical erosion rate allow the controls on OCpetro oxidation to be assessed. Re has been shown to be closely associated with OCpetro in rocks and following oxidation during chemical weathering forms a soluble oxyanion (ReO4−) which contributes to the dissolved load of rivers. Soils on meta-sedimentary rocks in Taiwan show that Re loss is coupled to OCpetro loss during weathering, confirming previous observations from soil profiles on sedimentary rocks elsewhere. In Taiwan rivers, dissolved Re flux increases with the catchment-average sediment yield, suggesting that physical erosion rate is a major control on OCpetro oxidation. Based on our current understanding of Re mobility during weathering, the dissolved Re flux can be used to quantify an upper bound on the OCpetro oxidation rate and the associated CO2 transfer. The estimated CO2 release from this mountain belt by OCpetro oxidation does not negate estimates of CO2 sequestration by burial of biospheric OC offshore. The findings are compared to OC transfers estimated for the Himalaya, where OCpetro oxidation in the mountain belt remains unconstrained. Together, these cases suggest that mountain building in the tropics can result in a net sink of OC which sequesters atmospheric CO2
Complications in the study of ancient tuberculosis: Presence of environmental bacteria in human archaeological remains

AbstractThere are many reports of ancient DNA from bacteria of the Mycobacterium tuberculosis complex (MTBC) being present in skeletons with and without osteological indications of tuberculosis. A possible complication in these studies is that extracts might also contain DNA from the microbiome of the individual whose remains are being analysed and/or from environmental bacteria that have colonised the skeleton after death. These contaminants might include ‘mycobacteria other than tuberculosis’ (MOTT), which are common in the environment, but which are not normally associated with clinical cases of tuberculosis. In this paper we show that MOTT of various types, as well as bacteria of related genera, are present in most if not all archaeological remains. Our results emphasise the complications inherent in the biomolecular study of archaeological human tuberculosis. The specificity of any polymerase chain reaction directed at the MTBC cannot be assumed and, to confirm that an amplification is authentic, a sequencing strategy must be applied that allows characterisation of the PCR product. Any variations from the reference MTBC sequence must then be checked against sequence data for MOTT and other species to ensure that the product does actually derive from MTBC. Our results also illustrate the challenges faced when assembling MTBC genome sequences from ancient DNA samples, as misidentification of MOTT sequence reads as MTBC would lead to errors in the assembly. Identifying such errors would be particularly difficult, if not impossible, if the MOTT DNA content is greater than that of the authentic MTBC. The difficulty in identifying and excluding MOTT sequences is exacerbated by the fact that many MOTT are still uncharacterized and hence their sequence features are unknown
A firm-level dataset for analyzing entry, exit, employment and R&D expenditures in the UK: 1997–2012

AbstractThis data article is related to the research article entitled “Inverted-U relationship between R&D intensity and survival: Evidence on scale and complementarity effects in UK data” (Ugur et al., In press) [1]. It describes the trends in R&D expenditures, employment of R&D personnel and firm entry and exit rates in the UK from 1998 to 2012. We also provide statistics on net employment creation and net R&D investments due to firm entry and exits. In addition, we compute the correlation coefficients between entry and exit rates at the two digit industry level so as to examine whether the correlations are contemporaneous or inter-temporal. Finally, we provide information about the underlying dataset to which secure access is available through UK Data Service Archive 7716 at http://dx.doi.org/10.5255/UKDA-SN-7716-1
Ginzburg–Landau minimizers with prescribed degrees. Capacity of the domain and emergence of vortices

AbstractLet Ω⊂R2 be a simply connected domain, let ω be a simply connected subdomain of Ω, and set A=Ω∖ω. Suppose that J is the class of complex-valued maps on the annular domain A with degree 1 both on ∂Ω and on ∂ω. We consider the variational problem for the Ginzburg–Landau energy Eλ among all maps in J. Because only the degree of the map is prescribed on the boundary, the set J is not necessarily closed under a weak H1-convergence. We show that the attainability of the minimum of Eλ over J is determined by the value of cap(A)—the H1-capacity of the domain A. In contrast, it is known, that the existence of minimizers of Eλ among the maps with a prescribed Dirichlet boundary data does not depend on this geometric characteristic. When cap(A)⩾π (A is either subcritical or critical), we show that the global minimizers of Eλ exist for each λ>0 and they are vortexless when λ is large. Assuming that λ→∞, we demonstrate that the minimizers of Eλ converge in H1(A) to an S1-valued harmonic map which we explicitly identify. When cap(A)<π (A is supercritical), we prove that either (i) there is a critical value λ0 such that the global minimizers exist when λ<λ0 and they do not exist when λ>λ0, or (ii) the global minimizers exist for each λ>0. We conjecture that the second case never occurs. Further, for large λ, we establish that the minimizing sequences/minimizers in supercritical domains develop exactly two vortices—a vortex of degree 1 near ∂Ω and a vortex of degree −1 near ∂ω
Electron Paramagnetic Resonance Characterization of Tetrahydrobiopterin Radical Formation in Bacterial Nitric Oxide Synthase Compared to Mammalian Nitric Oxide Synthase

AbstractH4B is an essential catalytic cofactor of the mNOSs. It acts as an electron donor and activates the ferrous heme-oxygen complex intermediate during Arg oxidation (first step) and NOHA oxidation (second step) leading to nitric oxide and citrulline as final products. However, its role as a proton donor is still debated. Furthermore, its exact involvement has never been explored for other NOSs such as NOS-like proteins from bacteria. This article proposes a comparative study of the role of H4B between iNOS and bsNOS. In this work, we have used freeze-quench to stop the arginine and NOHA oxidation reactions and trap reaction intermediates. We have characterized these intermediates using multifrequency electron paramagnetic resonance. For the first time, to our knowledge, we report a radical formation for a nonmammalian NOS. The results indicate that bsNOS, like iNOS, has the capacity to generate a pterin radical during Arg oxidation. Our current electron paramagnetic resonance data suggest that this radical is protonated indicating that H4B may not transfer any proton. In the 2nd step, the radical trapped for iNOS is also suggested to be protonated as in the 1st step, whereas it was not possible to trap a radical for the bsNOS 2nd step. Our data highlight potential differences for the catalytic mechanism of NOHA oxidation between mammalian and bacterial NOSs
Electroweak effects in the double Dalitz decay Bs→l+l−l′+l′−

AbstractWe investigate the double Dalitz decays Bs→l+l−l′+l′− on the basis of the effective Hamiltonian for the transition bs̄→l+l−, and universal form factors suggested by QCD. The correlated mass spectrum of the two lepton pairs in the decay Bs→e+e−μ+μ− is derived in an efficient way, using a QED result for meson decays mediated by two virtual photons: Bs→γ∗γ∗→e+e−μ+μ−. A comment is made on the correlation between the planes of the two lepton pairs. The conversion ratios ρlll′l′=Γ(Bs→l+l−l′+l′−)Γ(Bs→γγ) are estimated to be ρeeee=3×10−4,ρeeμμ=9×10−5 and ρμμμμ=3×10−5, and are enhanced relative to pure QED by 10–30%
Interface Model between the Bioreactor and the Membrane in a Membrane Bioreactor for Wastewater Treatment

AbstractThis paper proposes a structure of an integrated mathematical model of a membrane bioreactor (MBR) and describes the links between two main parts of a MBR model: the bioreactor and the membrane. In case of an immersed MBR three types of links are considered: a relationship between specific cake resistance (SCR) and extracellular polymeric substances (EPS) in the bioreactor, a relationship between air scour rate and shear stresses on the membrane surface, and a relationship between concentration of soluble microbial products (SMP) in the bioreactor and rate of pore constriction. While SMP concentration features directly in the equations of pore constriction, EPS are assumed to affect SCR which in turn has an effect on cake filtration. The relationship between EPS and SCR is described with a linear algebraic equation. Shear stresses on the membrane surface are calculated as a function of air scour rate with a one-dimensional slug flow model
A unified approach to nuclei: The BPS Skyrme Model

AbstractWe present a concrete model of a low energy effective field theory of QCD, the well-known Skyrme Model. Specifically, we will work with the BPS submodel in order to describe the binding energies of nuclei. This BPS Skyrme model is characterized by having a saturated bound for the energy proportional to the baryon number of the nuclei. After presenting this classical result, we will proceed with a semi-classical quantization of the coordinates of spin and isospin. Then, with the further inclusion of the Coulomb interaction as well as a small explicit breaking of the isospin symmetry, we finally calculate the binding energies of nuclei, where an excellent agreement has been found for the nuclei with high baryon number. Besides this, we also apply this model to the study of some thermodynamic properties and to neutron stars
Limit on the production of a new vector boson in e+e−→Uγ, U→π+π− with the KLOE experiment

AbstractThe recent interest in a light gauge boson in the framework of an extra U(1) symmetry motivates searches in the mass range below 1 GeV. We present a search for such a particle, the dark photon, in e+e−→Uγ, U→π+π− based on 28 million e+e−→π+π−γ events collected at DAΦNE by the KLOE experiment. The π+ π− production by initial-state radiation compensates for a loss of sensitivity of previous KLOE U→e+e−, μ+μ− searches due to the small branching ratios in the ρ–ω resonance region. We found no evidence for a signal and set a limit at 90% CL on the mixing strength between the photon and the dark photon, ε2, in the U mass range between 527 and 987MeV. Above 700 MeV this new limit is more stringent than previous ones
Supersymmetric solutions of N=2, D=4 SUGRA: The whole ungauged shebang

AbstractIn this article we complete the classification of the supersymmetric solutions of N=2, D=4 ungauged supergravity coupled to an arbitrary number of vector- and hypermultiplets.We find that in the timelike case the hypermultiplets cause the constant-time hypersurfaces to be curved and have SU(2) holonomy identical to that of the hyperscalar manifold. The solutions have the same structure as without hypermultiplets but now depend on functions which are harmonic in the curved 3-dimensional space. We discuss an example obtained from a hyper-less solution via the c-map.In the null case we find that the hyperscalars can only depend on the null coordinate and the solutions are essentially those of the hyper-less case
Revisiting leishmaniasis in the time of war: the Syrian conflict and the Lebanese outbreak

SummaryBackgroundLeishmaniasis is a neglected tropical disease, endemic in many worldwide foci including the Middle East. Several outbreaks have occurred in the Middle East over the past decades, mostly related to war-associated population migration. With the start of the Syrian war, the frequency and magnitude of these outbreaks increased alarmingly. We describe the epidemiology of Leishmania infection in Lebanon and the most recent outbreak relevant to the Syrian war.MethodsWe reviewed all leishmaniasis cases reported to the Epidemiologic Surveillance Department at the Lebanese Ministry of Public Health between 2001 and the first quarter of 2014. The demographics and distribution of Syrian refugees in Lebanon were linked to reports of new Leishmania cases.ResultsIn total, 1033 new cases of leishmaniasis were reported in 2013 compared to a previous annual number in the range of 0–6 cases. The majority of cases reported in 2013 involved Syrian refugees and their relevant areas of concentration.ConclusionsThis new outbreak of leishmaniasis in Lebanon is the first of its kind for more than a decade. The sudden increase in Leishmania cases in Lebanon in 2013 is attributed to the increasing numbers and wide distribution of Syrian refugees in Lebanon. This serves as an example of the risks associated with military conflicts and the ability of communicable diseases to cross borders
