description: Background: It has been agreed upon by educators and scholars that one of the key successes in any educational setting is promoting the professional development of teachers. Having this in mind, the researchers of the present study investigated nursing English for academic purposes (EAP) and instructors’ perceptions of knowledge sharing. In addition, they sought whether EAP instructors’ perceptions of knowledge sharing would predict their professional development. Methods: Ninety-four EAP instructors from different medical universities across the country were recruited in the present study. Two questionnaires of ‘EAP instructors’ perception towards knowledge sharing’ scale and ‘a teacher professional development’ were used to gather data. A semi-structured interview was also performed to explore the participants’ opinions regarding the inhibitors to develop teacher learning communities. Results: The results showed that the mean of EAP instructors' perception of knowledge sharing in the sample group was 2.90 with a standard deviation of 0.338 which was lower than the expected average (3). Also, there was a positive and significant relationship between the perception of EAP instructors and knowledge sharing with respect to the level of significance (sig= 0.000) and the error rate of 0.01 with their professional development. In addition, the multiple regression analysis showed that cultural, reflective, personal cost and sharing, and organizational variables were able to explain the variance of professional development. As the findings of the semi-structured interview revealed, among other factors, instructors’ lack of incentive, lack of commitment, and their lack of familiarity with the importance of teacher learning communities were the major inhibitors to developing teacher learning communities among EAP instructors. Conclusion: Knowledge management can become a rudimentary strategy which may pave the way to personal/professional development. This sheds light on the importance of collaborative work which should take place within an educational setting. Accordingly, some implications have been suggested to encourage knowledge sharing among EAP instructors.

description: Image based diagnostics are interpreted in the context of spatial resolution. The same is true for tomographic image reconstruction. Current empirically driven approaches to quantify spatial resolution rely on a deterministic formulation based on point-spread functions which neglect the statistical prior information, that is integral to rank-deficient tomography. We propose a statistical spatial resolution measure based on the covariance of the reconstruction (point estimate) and show that the prior information acts as a lower limit for the spatial resolution. Furthermore, the spatial resolution measure can be employed for designing tomographic systems under consideration of spatial inhomogeneity of spatial resolution.

description: We explore the theoretical foundations of a ``twenty questions'' approach to pattern recognition. The object of the analysis is the computational process itself rather than probability distributions (Bayesian inference) or decision boundaries (statistical learning). Our formulation is motivated by applications to scene interpretation in which there are a great many possible explanations for the data, one (``background'') is statistically dominant, and it is imperative to restrict intensive computation to genuinely ambiguous regions. The focus here is then on pattern filtering: Given a large set Y of possible patterns or explanations, narrow down the true one Y to a small (random) subset \hat Y\subsetY of ``detected'' patterns to be subjected to further, more intense, processing. To this end, we consider a family of hypothesis tests for Y\in A versus the nonspecific alternatives Y\in A^c. Each test has null type I error and the candidate sets A\subsetY are arranged in a hierarchy of nested partitions. These tests are then characterized by scope (|A|), power (or type II error) and algorithmic cost. We consider sequential testing strategies in which decisions are made iteratively, based on past outcomes, about which test to perform next and when to stop testing. The set \hat Y is then taken to be the set of patterns that have not been ruled out by the tests performed. The total cost of a strategy is the sum of the ``testing cost'' and the ``postprocessing cost'' (proportional to |\hat Y|) and the corresponding optimization problem is analyzed.

description: Product and process innovations are prime manifestations of innovativeness by an organization. Yet surprisingly little is known regarding how to initiate and maintain the innovative momentum in organizations with the ultimate target to produce an increasing number of product innovations and improve competitiveness. Of major concern has been however, the sheer volume of contributions on the subject and the complexity of issues involved. An extensive literature review has been carried out covering 400 scientific Journals during a 10-year long period (1991-2001). Over 2500 journal articles have been identified as relevant and read. Their contribution to the subject of product innovations (i.e., process innovations are not covered) has been identified using a multitude of literature mapping techniques. The present article summarizes the contributions of individual articles depicting the current state-of-the-art in the area.

Microbial processes in the subarctic northeast Pacific : bacterial standing stocks, rate processes, and controls

description: During 11 cruises along the east/west line-P transect from slope waters at P4 (1200 m depth) to the open-ocean waters at Ocean Station Papa (OSP) (4250 m depth), heterotrophic bacterial abundance, productivity, and respiration rates were measured. While values from below the euphotic zone (-60 - 4200 m) are reported, detailed analysis is focused primarily on the euphotic zone. Within the euphotic zone, bacterial biomass in the winter was -50% of the spring and summer values. Bacterial respiration rates in the summer increased > 10-fold at P4 while showing much less change at the more oceanic stations. Bacterial productivity, measured as [ H]-thymidine and [14C]-leucine incorporation rates, was lowest in the winter with little spatial variability. Productivity increased 4 to 10-fold in spring at P4. Between 1995 and 1998, the average summer bacterial abundance along line-P decreased by -50% while bacterial productivity decreased by - 90%. Factors for converting the incorporation of radiolabeled substrate to bacterial productivity were determined empirically from grow-out dilution experiments. The empirical conversion factors for both thymidine and leucine were positively correlated to in situ cell abundance. A grow-out simulation model was developed and used to quantify the uncertainties associated with various conversion factor calculation methods leading to a more robust, non-linear cumulative method for calculating conversion factors. Roughly 10%o of the mixed-layer data showed extremely high bacterial productivity which was associated with physical features or fronts. Seasonal changes in bacterial abundance, productivity, and growth rate were driven predominantly by changes in the supply rate of phytoplankton derived dissolved organic carbon (DOC), and by changes in the dilution of surface water by deeper water (deepening of the mixed layer and/or changes in upwelling). Regional changes in bacterial abundance, productivity, and growth rate during the summer were driven predominantly by differences in the availability of limiting mineral nutrients and changes in the rates of loss processes. Experimental manipulations demonstrated that bacterial productivity was almost always limited by the availability of labile DOC. However, bacterial productivity in the late summer was further limited at P4 in 1996 by the availability of nitrogen, and at OSP in 1997 by the availability of iron.

description: High-temperature superconductivity has been discovered in La2-xBaxCuO4 [1], a compound that derives from the undoped La2CuO4 crystallizing in the perovskite T-structure. In this structure oxygen octahedra surround the copper ions. It is common knowledge that charge carriers induced by doping in such an undoped antiferromagnetic Mott-insulator lead to high-temperature superconductivity [2- 4]. The undoped material La2CuO4 is also the basis of the electron-doped cuprate superconductors [5] of the form La2-xCexCuO4+y [6,7] which however crystallize in the so called T-prime-structure, i.e. without apical oxygen above or below the copper ions of the CuO2-plane. It is well known that for La2-xCexCuO4+y the undoped T-prime-structure parent compound cannot be prepared due to the structural phase transition back into the T-structure occuring around x ~ 0.05. Here, we report that if La is substituted by RE = Y, Lu, Sm, Eu, Gd, or Tb, which have smaller ionic radii but have the same valence as La, nominally undoped La2-xRExCuO4 can be synthesized by molecular beam epitaxy in the T-prime-structure. The second important result is that all these new T-prime-compounds are superconductors with fairly high critical temperatures up to 21 K. For this new class of cuprates La2-xRExCuO4, which forms the T-prime-parent compounds of the La-based electron doped cuprates, we have not been able to obtain the Mott-insulating ground state for small x before the structural phase transition into the T-structure takes place.

description: We report an investigation of Metal Insulator Transition (MIT) using conductivity and magnetoconductance (MC) measurements down to 0.3 K in Nd_{0.7}La_{0.3}NiO_{3} films grown on crystalline substrates of LaAlO_{3} (LAO), SrTiO_{3} (STO), and NdGaO_{3}(NGO) by pulsed laser deposition. The film grown on LAO experiences a compressive strain and shows metallic behavior with the onset of a weak resistivity upturn below 2 K which is linked to the onset of weak localization contribution. Films grown on STO and NGO show a crossover from a Positive Temperature Coefficient (PTC) resistance regime to Negative Temperature Coefficient (NTC) resistance regime at definite temperatures. We establish that a cross-over from PTC to NTC on cooling does not necessarily constitute a MIT because the extrapolated conductivity at zero temperature σ_{0} though small (<10 S/cm) is finite, signalling the existence of a bad metallic state and absence of an activated transport. The value of σ_{0} for films grown on NGO is reduced by a factor of 40 compared to that for films grown on STO. We show that a combination of certain physical factors makes substituted nickelate (that are known to exhibit first order Mott type transition), undergo a continuous transition as seen in systems undergoing disorder/composition driven Anderson transition. The MC measurement also support the above observation and show that at low temperature there exists a positive MC that arises from the quantum interference which co-exists with a spin-related negative MC that becomes progressively stronger as the electrons approach a strongly localized state in the film grown on NGO.

description: The purpose of this paper is to assess the relation between accounting comparability and earning management method selection. Comparability is a qualitative characteristic of accounting information. It makes information users' able to identify and understand similarities and differences between two set of information and use them in their decision making. Accrual earning management is a potential factor which can seriously damage comparability. We defined comparability as a characteristic of accounting system outputs and the assessed companies' return and earning which were in an industry. We examined a sample of 72 companies of the Tehran stock exchange in 6 industries during 2005 to 2015. Findings show that accounting comparability has no relation with real and accrual earning management.

description: Energy dissipation by fast crystalline defects takes place mainly through the resonant interaction of their cores with periodic lattice. We show that the resultant effective friction can be reduced to zero by appropriately tuned acoustic sources located on the boundary of the body. To illustrate the general idea, we consider three prototypical models describing the main types of strongly discrete defects: dislocations, cracks and domain walls. The obtained control protocols, ensuring dissipation-free mobility of topological defects, can be also used in the design of meta-material systems aimed at transmitting mechanical information.

In letzter Zeit wurde vor allem der flexible Verlauf der mehr oder weniger bewussten Tempogestaltung innerhalb ganzer Werkstrukturen, bisweilen bis hin zu Prozessen im Rahmen einzelner Takte und Übergänge erforscht. Dabei ging es zumeist um Werke des klassisch-romantischen Repertoires, vorzugsweise um Klavier-, bisweilen auch um Orchestermusik.

description: We show that the superconducting transition temperature T_c(H) of a very thin highly disordered film with strong spin-orbital scattering can be increased by parallel magnetic field H. This effect is due to polarization of magnetic impurity spins which reduces the full exchange scattering rate of electrons; the largest effect is predicted for spin-1/2 impurities. Moreover, for some range of magnetic impurity concentrations the phenomenon of {\it superconductivity induced by magnetic field} is predicted: superconducting transition temperature T_c(H) is found to be nonzero in the range of magnetic fields $0 < H^* <= H <= H_c$.

description: We propose a scheme in that the masses of the heavier leptons obey seesaw type relations. The light lepton masses, except the electron and the electron neutrino ones are generated by one loop level radiative corrections. We work in a version of the 3-3-1 electroweak model that predicts singlets (charged and neutral) of heavy leptons beyond the known ones. An extra U(1)_Omega symmetry is introduced in order to avoid the light leptons get masses at the tree level. The electron mass induces an explicit symmetry breaking at U(1). We discuss also the mixing matrix among four neutrinos. The new energy scale required is not higher than a few TeV.

description: We consider production of prompt photons in high energy gold-gold and deuteron-gold collisions in the forward rapidity region of RHIC ($y \sim 3.8$). In this kinematics, the projectile partons typically have large $x_{bj}$ while the target partons are mostly at very small $x_{bj}$ so that the primary partonic collisions involve valence quarks from the projectile and gluons from the target. We take the target nucleus to be a Color Glass Condensate while the projectile deuteron or nucleus is treated as a dilute system of partons. We show that the photon production cross section can be written as a convolution of a quark-nucleus scattering cross section, involving a quark anti-quark dipole, with the Leading Order quark-photon fragmentation function. We consider different models of the quark anti-quark dipole and show that measurement of photons in the forward rapidity region at RHIC can distinguish between different parameterizations of the dipole cross section as well as help clarify the role of parton coalescence models in hadron production at RHIC.

description: Event logs capture the execution of business processes in terms of executed activities and their execution context. Since logs contain potentially sensitive information about the individuals involved in the process, they should be pre-processed before being published to preserve the individuals' privacy. However, existing techniques for such pre-processing are limited to a process' control-flow and neglect contextual information, such as attribute values and durations. This thus precludes any form of process analysis that involves contextual factors. To bridge this gap, we introduce PRIPEL, a framework for privacy-aware event log publishing. Compared to existing work, PRIPEL takes a fundamentally different angle and ensures privacy on the level of individual cases instead of the complete log. This way, contextual information as well as the long tail process behaviour are preserved, which enables the application of a rich set of process analysis techniques. We demonstrate the feasibility of our framework in a case study with a real-world event log.

description: Novel randomness-induced disordered ground states in two-dimensional (2D) quantum spin systems have been attracting much interest. For quantitative analysis of such random quantum spin systems, one of the most promising numerical approaches is the tensor-network strong-disorder renormalization group (tSDRG), which was basically established for one-dimensional (1D) systems. In this paper, we propose a possible improvement of its algorithm toward 2D random spin systems, focusing on a generating process of the tree network structure of tensors, and precisely examine their performances for the random antiferromagnetic Heisenberg model not only on the 1D chain but also on the square- and triangular-lattices. On the basis of comparison with the exact numerical results up to 36 site systems, we demonstrate that accuracy of the optimal tSDRG algorithm is significantly improved even for the 2D systems in the strong-randomness regime.

description: Let $N \geq2$ and let $1 < a_1 < ... < a_N$ be relatively prime integers. Frobenius number of this $N$-tuple is defined to be the largest positive integer that cannot be expressed as $\sum_{i=1}^N a_i x_i$ where $x_1,...,x_N$ are non-negative integers. The condition that $gcd(a_1,...,a_N)=1$ implies that such number exists. The general problem of determining the Frobenius number given $N$ and $a_1,...,a_N$ is NP-hard, but there has been a number of different bounds on the Frobenius number produced by various authors. We use techniques from the geometry of numbers to produce a new bound, relating Frobenius number to the covering radius of the null-lattice of this $N$-tuple. Our bound is particularly interesting in the case when this lattice has equal successive minima, which, as we prove, happens infinitely often.

description: Multilamellar wall vesicles (MLWV) are an interesting class of polyelectrolyte-surfactant complexes (PESCs) for wide applications ranging from house-care to biomedical products. If MLWV are generally obtained by a polyelectrolyte-driven vesicle agglutination under pseudo-equilibrium conditions, the resulting phase is often a mixture of more than one structure. In this work, we show that MLWV can be massively and reproductively prepared from a recently developed method involving a pH-stimulated phase transition from a complex coacervate phase (Co). We employ a biobased pH-sensitive microbial glucolipid biosurfactant in the presence of a natural, or synthetic, polyamine (chitosan, poly-L-Lysine, polyethylene imine, polyallylamine). In situ small angle X-ray scattering (SAXS) and cryogenic transmission electron microscopy (cryo-TEM) show a systematic isostructural and isodimensional transition from the Co to the MLWV phase, while optical microscopy under polarized light experiments and cryo-TEM reveal a massive, virtually quantitative, presence of MLWV. Finally, the multilamellar wall structure is not perturbed by filtration and sonication, two typical methods employed to control size distribution in vesicles. In summary, this work highlights a new, robust, non-equilibrium phase-change method to develop biobased multilamellar wall vesicles, promising soft colloids with applications in the field of personal care, cosmetics and pharmaceutics among many others.

description: In our model, $n$ traders interact with each other and with a central bank; they are taxed on the money they make, some of which is dissipated away by corruption. A generic feature of our model is that the richest trader always wins by 'consuming' all the others: another is the existence of a threshold wealth, below which all traders go bankrupt. The two-trader case is examined in detail,in the socialist and capitalist limits, which generalise easily to $n>2$. In its mean-field incarnation, our model exhibits a two-time-scale glassy dynamics, as well as an astonishing universality.When preference is given to local interactions in finite neighbourhoods,a novel feature emerges: instead of at most one overall winner in the system,finite numbers of winners emerge, each one the overlord of a particular region.The patterns formed by such winners (metastable states) are very much a consequence of initial conditions, so that the fate of the marketplace is ruled by its past history; hysteresis is thus also manifested.

description: Probability of the effects of demographical factors such as ethnicity, geographical area and age range on the behaviors of investors in the stock market has not been studied as much as those of the financial and economic variables. This study aims at investigating the relationship between ethnicity, geographical area, and age range of investors and their Herd behaviors. Chung et al's formula was used for recognizing Herd behaviors. Based on their model, when the result of deviation of stock return from market return decreases; a Herd behavior appears. Research sample involved 388718 investors from Tehran Stock Exchange (TSE). The study was conducted during 2012- 2015. The obtained results revealed a significant relationship between ethnicity (except Arab ethnicity), geographical area (except the southern area), and age range; and Herd behaviors of investors

description: Policy discussions of agricultural pollution problems characterize prevention as more cost effective and precautionary than ex post treatment. We derive conditions under which treatment alone is more cost effective in situations involving multiple sources of emissions, multiple sites affected, and a commonly used precautionary approach to uncertainty. We also show that a greater degree of precaution can result in less reliance on prevention. An empirical case study indicates that treatment alone is the most cost effective means of dealing with nitrate in most Maryland community water system wells. The use of leaching prevention measures is restricted to the most intensive poultry producing areas. The incremental cost of precaution is substantial.

description: We consider the problem of adaptation to the margin in binary classification. We suggest a penalized empirical risk minimization classifier that adaptively attains, up to a logarithmic factor, fast optimal rates of convergence for the excess risk, that is, rates that can be faster than n^{-1/2}, where n is the sample size. We show that our method also gives adaptive estimators for the problem of edge estimation.

description: Quantum electrodynamical (QED) calculations of ionization energies of the $1snd\,D$ states are performed for the helium atom. We reproduce the previously known relativistic and QED effects up to order $mα^5$ and extend the theory by calculating the complete $mα^6$ correction. The total contribution of the $mα^6$ effects is shown to be much smaller than previously estimated, due to a large cancelation between the radiative and non-radiative parts of this correction. As a result of our calculations, we confirm the previously reported deviations between measured transition energies and theoretical predictions for the $nD$--$2S$ and $nD$--$2P$ transitions. Possible reasons for this discrepancy are analyzed.
Work distribution and path integrals in general mean-field systems

description: We consider a mean-field system described by a general collective variable $M$, driven out of equilibrium by the manipulation of a parameter $μ$. Given a general dynamics compatible with its equilibrium distribution, we derive the evolution equation for the joint probability distribution function of $M$ and the work $W$ done on the system. We solve this equation by path integrals. We show how the Jarzynski equality holds identically at the path integral level and for the classical paths which dominate the expression in the thermodynamic limit. We discuss some implications of our results.

Updated theoretical Period-Age and Period-Age-Color relations for Galactic Classical Cepheids: an application to the Gaia DR2 sample

description: Updated evolutionary and pulsational model predictions are combined in order to interpret the properties of Galactic Classical Cepheids in the Gaia Data Release 2. In particular, the location of the instability strip boundaries and the analytical relations connecting pulsation periods to the intrinsic stellar parameters are combined with evolutionary tracks to derive reliable and accurate period-age, and the first theoretical period-age-color relations in the Gaia bands for a solar chemical abundance pattern ($Z$=$0.02$, $Y$=$0.28$). The adopted theoretical framework takes into account possible variations in the mass-luminosity relation for the core helium-burning stage as due to changes in the core convective overshooting and/or mass loss efficiency, as well as the impact on the instability strip boundaries due to different assumptions for superadiabatic convection efficiency. The inferred period-age and period-age-color relations are applied to a selected sample of both fundamental and first overtone Gaia Cepheids, and individual ages for the various adopted theoretical scenarios are derived. The retrieved age distributions confirm that a variation in the efficiency of superadiabatic convection in the pulsational model computations has a negligible effect, whereas a brighter Mass-Luminosity relation, as produced by mild overshooting, rotation or mass loss, implies significantly older age predictions. Moreover, older Cepheids are found at larger Galactocentric distances, while first overtone Cepheids are found to be systematically older than the fundamental ones. The comparison with independent age distribution analysis in literature supports the predictive capability of current theoretical framework.

description: The detection of the Cosmic Microwave Background Radiation (CMB) was one of the most important cosmological discoveries of the last century. With the development of interferometric gravitational wave detectors, we may be in a position to detect the gravitational equivalent of the CMB in this century. The Cosmic Gravitational Background (CGB) is likely to be isotropic and stochastic, making it difficult to distinguish from instrument noise. The contribution from the CGB can be isolated by cross-correlating the signals from two or more independent detectors. Here we extend previous studies that considered the cross-correlation of two Michelson channels by calculating the optimal signal to noise ratio that can be achieved by combining the full set of interferometry variables that are available with a six link triangular interferometer. In contrast to the two channel case, we find that the relative orientation of a pair of coplanar detectors does not affect the signal to noise ratio. We apply our results to the detector design described in the Big Bang Observer (BBO) mission concept study and find that BBO could detect a background with $Ω_{gw} > 2.2 \times 10^{-17}$.

description: When manure nutrients exceed a county's cropland assimilative capacity, the potential for water quality problems exists. Concerns about water quality have led to the passage of the Water Quality Improvement Act in Maryland which will impact the disposal of poultry litter on cropland. Forest fertilization may be an alternative use for the litter. Forest landowners indicated their willingness to use poultry litter as a forest fertilizer under a variety of incentives. Landowners with more acres, in certain counties, and who were younger were most likely to be willingness. Surprisingly, landowners who work with foresters were not more likely to agree, suggesting that foresters may not know about the potential benefits of poultry litter application in timber growth.

description: The EOS of strongly interacting matter at densities ten to fifteen orders of magnitude larger than the typical density of terrestrial macroscopic objects determines a number of neutron star properties, including the pattern of gravitational waves emitted following the excitation of nonradial oscillation modes. This paper reviews some of the approaches employed to model neutron star matter, as well as the prospects for obtaining new insights from the experimental study of gravitational waves emitted by neutron stars.

description: We study the interfacial structure, stability, and elastic properties of composite carbon films containing nanotubes. Our Monte Carlo simulations show that Van der Waals forces play a vital role in shaping up the interfacial geometry, producing a curved graphitic wall surrounding the tubes. The most stable structures are predicted to have intermediate densities, high anisotropies, and increased elastic moduli compared to pure amorphous carbon films.
