Talent Management Practices and Its Impact on Intention to Stay in the Organisation

In today’s dynamic business environment, organizations are looking to add new and improved or innovative capabilities to their portfolio of business. To achieve these objectives organizations need to add a very vital component called human resources. Therefore, Talent management is the buzzword in the IT sector to attract and retain a talented workforce. The current research paper aims to explore the attitude of the employees towards the major factors that influence the talent management practices in Indian IT firms intending to stay in the organization. To realize the stated objectives the researchers have collected the primary data from two hundred talented employees across the IT sector. In this context talented means one has consistently been a top performer or received the best employee or star performer reward or recognition from the employer for at least two years in a specific domain. For this purpose, the researchers have identified eight major factors such as quality of supervision, Compensation Management practices, job engagement, innovation practices, open climate, Career Development Path, organizational Environment, and quality of working Environment. The multiple regression model results revealed that the independent variable Compensation management, Job engagement, Open climate, Organizational environment, and quality of working environment were the major drivers of intention to stay in the current organization. When we rank the determinants we found the most prominent determinant being Job Engagement followed by Quality of working environment, Open climate, Compensation management, and Organizational environment. The current study makes significant contributions to both talent management theory and practices. Firstly, we provide empirical support from the perspective of employees about the various talent management practices and strategies employed by various IT companies in the Indian context. Secondly, we provide a scheme of suggestions to IT firms across the sector and various strategies to retain the talented workforce. Thirdly, we have ranked the various variables chosen for the study based on the empirical evidence and suggested the managers' various interventions to nurture and retain the talented workforce. Additionally, the current paper is aimed to assist managers with some of the vital issues they face with the implementation of talent management strategies.
Electron relaxation in metals and high-Tc superconductors on the 10-fs timescale

We perform two-colour pump probe experiments on metals and superconductors using synchronized 10-fs pulses generated by optical parametric amplifiers, tunable from the visible to the near-infrared, mapping with unprecedented detail the energy equilibration dynamics of the free electron gas. In gold films we observe dramatic changes of the differential reflectivity spectrum on the 100-fs timescale, corresponding to the establishment of the thermal electron distribution, with dynamics dictated by excess energy. In high-Tc cuprate superconductors we observe fast electron relaxation, attributed to a strong electron-phonon coupling which may play a role in the superconductivity mechanism.
A new approach of modeling micromachining parts with a shaped generatrix by image processing of tool's cutting surface

A method for microprocessing products with a shaped generatrix by remote the product from the image is proposed, which provides an increase in productivity without loss of quality. The method allows you to recreate an object based on image reconstruction with basic accuracy requirements and establish a rational trajectory of the turning tool on CNC machines. The method is implemented as follows: a cylindrical workpiece is fixed in the machine spindle, the plate is installed in the turning body cutter, a preliminary positioning of the cutter is performed and its fixation in the working area of the machine with a special trajectory of movement obtained on the basis of the recognized profile of the product during reverse engineering. As a result, the new method allows increasing the productivity of the treated surface up to 2 times, depending on the shape and accuracy of the object being reconstructed.
A variation rate measure for the arrhythmia via Poincaré plot

Arrhythmia is a common cardiac disease. Hence the diagnosis and treatment of arrhythmia is important problem for public health in our country. For the auxiliary diagnosis of devices, the features of arrhythmia are used to recognize the cardiac disease. Therefore, how to extract the effective features of arrhythmia is the key problem. In this paper, a variation rate measure (VRM) for arrhythmia is presented. Via the quantitative index VRM, the change degree of RR intervals for arrhythmia can be described effectively. Experiment results demonstrate that the arrhythmia can be recognized and classified effectively. Hence, VRM can be as a valid feature of the arrhythmia.
Polarization dependence of quasi-phase-matched second-harmonic generation in bulk periodically poled LiNbO3

Numerical comparisons of the acceptance bandwidths for quasi-phase-matched E Zω E Zω–E Z2ω (ee–e) and EYω EYω–EZ 2ω (oo–e) second-harmonic generation processes in bulk periodically poled LiNbO3 (PPLN) are given. The larger acceptance bandwidths and grating periods for the latter process lower the fabrication constraints, especially in the short-wavelength region, and also enhance the frequency conversion efficiency. The corresponding (oo–e) quasi-phase-matching conditions in bulk PPLN are discussed for different fundamental wavelength regions.
Explosive hydrogen burning

The nuclear energy generation and nucleosynthesis that occur in hydrogen-rich compositions at temperatures substantially greater than 10/sup 8/ K are examined in detail. At these high temperatures, a new kind of nucleosynthetic process (the ''rp-process'') involving the rapid capture of protons on seed nuclei (or on the products of helium burning in a situation with zero initial metallicity) can lead to the production of heavy elements up to and beyond the iron group with an accompanying energy generation rate greatly modified from that of the . beta. -limited CNO cycle customarily employed in such calculations. New nuclear reaction rates of interest are tabulated, and reaction network calculations are presented to illustrate the application of this process to exploding supermassive stars, accreting neutron star, novae, and certain chaotic cosmologies. Implications for . gamma. -line astronomy and X-ray burst models are discussed.
Indium tin oxide-free and metal-free semitransparent organic solar cells

We report on indium tin oxide (ITO)-free and metal-free semitransparent organic solar cells with a high-conductivity poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) (PH1000) as both the bottom and the top electrodes. The PH1000 film showed a conductivity of 680±50 S/cm. A ZnO layer was used as an interlayer to produce an electron-selective electrode. The semitransparent devices with a structure of glass/PH1000/ZnO/poly(3-hexylthiophene):phenyl-C61-butyric acid methyl ester/PEDOT:PSS (CPP 105 D)/PH1000 exhibited an average power conversion efficiency of 1.8% estimated for 100 mW/cm2 air mass 1.5 global illumination. This geometry alleviates the need of vacuum deposition of a top electrode.
Counterflow driven by swirl decay

The global meridional circulation of a viscous fluid, caused by swirl decay in a cylindrical container, is studied. To this end, a new solution to the Navier–Stokes equations is obtained, and simple experiments are performed to verify the predictions of the theory. The swirl decay mechanism explains elongated counterflows in hydrocyclones and vortex tubes sometimes extending over a hundred diameters.
The Role of Dual-Mobility Components in Total Hip Arthroplasty

➤ Dual mobility (DM) refers to a now widely available option for total hip articulation. DM implants feature a small inner head, a hard bearing, that connects via a taper fit onto the femoral trunnion. This head freely rotates but is encased inside a larger, outer polyethylene head that articulates with a smooth acetabular component. ➤ DM acetabular components are available in the form of a monoblock shell or as a liner that is impacted into a modular shell, providing a metal articulation for the polyethylene outer head. ➤ DM is designed to increase hip stability by providing the arthroplasty construct with a higher jump distance, head-to-neck ratio, and range of motion prior to impingement. ➤ The use of DM in total hip arthroplasty continues to increase in the United States for both primary and revision arthroplasty. Surgeons should be aware of the potential benefits and pitfalls. ➤ Long-term data are lacking, especially for modular DM implants. Points of concern include a potential for accelerated polyethylene wear, intraprosthetic dislocation, and modular backside fretting corrosion.
Exact solutions for redistribution by nonlinear convection-diffusion

Abstract The nonlinear convection-diffusion equation has been studied for 40 years in the context of nonhysteretic water movement in unsaturated soil. We establish new similarity solutions for instantaneous sources of finite strength redistributed by nonlinear convection-diffusion obeying the dimensionless equation ∂θ/∂t = ∂ (θm ∂θ/∂z) − θm+1 ∂θ/∂z (m ≥ 0). For m = 0 (Burgers’ equation) solutions involve the error function, and for m = 1 Airy functions. Problems 1, 2, and 3 relate, respectively, to the regions 0 ≤ z ≤ ∞, –∞ ≤ z ≤ ∞, and –∞ ≤ z ≤ 0. Solutions for m = 0 have infinite tails, but for m > 0 and finite t, θ > 0 inside, and θ = 0 outside, a finite interval in z. At the slug boundary, θ(z) is tangential to the z-axis for 0 < m < 1; and it meets the axis obliquely for m = 1 and normally for m > 1. Illustrative results are presented. For Problems 1 and 2 (but not 3) finiteness of source strength sets an upper bound on Θ0, the similarity “concentration” at z = 0. The magnitude of convection relative to diffusion increases with Θ0; and apparently the dynamic equilibrium between the two processes, implied by the similarity solutions, ceases to be possible when Θ0 is large enough.
Enhanced magnetoelectric effect in core-shell particulate composites

A method for the preparation of magnetostrictive-piezoelectric particulate composites with enhanced magnetoelectric effect was developed. The composites were synthesized in situ forming a shell of barium titanate around nanoparticles of cobalt ferrite, varying the composition of the cobalt ferrite magnetostrictive phase from 20to60wt. %. Cobalt ferrite nanoparticles were obtained by coprecipitation and then added to the precursor gel of barium titanate, allowing the in situ formation of the composite and thereby restricting the contact of the ferrite particles during sintering. The samples were sintered at a temperature ranging from 1100to1250°C for 12h, followed by a plating step to be electrically poled. Additional samples were prepared by conventional mechanical milling for comparison, starting from cobalt ferrite prepared either by coprecipitation or the sol-gel technique and commercial barium titanate. Samples of same compositions prepared by different methods and sintered under the same conditions sh.
Room-temperature intense 320 nm band ultraviolet emission from quaternary InAlGaN-based multiple-quantum wells

We demonstrated room-temperature (RT) intense ultraviolet (UV) emission with wavelength in the range of 300–340 nm from Inx1Aly1Ga1−x1−y1N/Inx2Aly2Ga1−x2−y2N multiple-quantum wells (MQWs) fabricated on SiC by metalorganic vapor phase epitaxy. We found that the UV emission is considerably enhanced upon introducing approximately 5% of In into AlGaN. Maximally efficient emission was obtained at 318 nm from the fabricated In0.05Al0. 34Ga0.61N/In0.02Al0. 60Ga0.38N three-layer MQW when the QW thickness was approximately 1.4 nm. The intensity of 320 nm band emission from the InAlGaN-based MQWs was as strong as that of 410 nm band emission from InGaN-based QWs at RT. We observed emission fluctuations of submicron size in cathode luminescence images of Inx1Aly1Ga1−x1−y1N/Inx2Aly2Ga1−x2−y2N single QW which might be due to In segregation effect. The temperature dependence of photoluminescence emission for InAlGaN-based QWs was greatly improved in comparison with that of GaN- or AlGaN-based QWs.
Synthetic Images and Long-Slit Spectra of Protostellar Jets

We construct synthetic images and long-slit spectra of protostellar jets modeled as steady state X-winds. Assuming uniform ionization fractions and electron temperatures, we calculate non-LTE level populations for five-level atoms. Synthetic images in the [S II] λ6716/λ6731 and [O I] λ6300/λ6364 lines have roughly the same surface brightness as observed jets if we ignore their knotty structure. Long-slit spectra taken with the slit placed along the central axis of the jet, or slightly displaced laterally from it, provide strong evidence in support of the X-wind theory. In both the models and the actual objects, wide line profiles, containing both large positive and negative velocities, are often seen at the base of the flow, indicative of a wide-angle wind. As one progresses up the length of the slit, the line profiles narrow to straddle the projected velocity of a highly collimated jet.
A Continuity Property Related to Kuratowski′s Index of Non-compactness, Its Relevance to the Drop Property, and Its Implications for Differentiability Theory

Abstract We define and study the properties of α upper semi-continuity, a new continuity property for set-valued mappings from a topological space into subsets of a metric space, expressed in terms of Kuratowski′s index of non-compactness. This α upper semi-continuity is related closely to the usual upper semi-continuity but significantly α upper semi-continuous minimal weak* cuscos from a Baire space into subsets of the dual of any Banach space are generically single-valued. Kuratowski′s index of non-compactness has been used to study the drop property and α upper semi-continuity is dual to property α studied there. Uniform α upper semi-continuity of the duality mapping is dual to nearly uniform rotundity properties. Importantly, α upper semi-continuity has application in differentiability theory, providing another characterisation for Asplund spaces. An examination of an associated concept, α-denting point for sets, yields still further advances concerning the differentiability of convex functions on a large class of Banach spaces.
Prospects of Biogenic Xanthan and Gellan in Removal of Heavy Metals from Contaminated Waters

Biosorption is considered an effective technique for the treatment of heavy-metal-bearing wastewaters. In recent years, various biogenic products, including native and functionalized biopolymers, have been successfully employed in technologies aiming for the environmentally sustainable immobilization and removal of heavy metals at contaminated sites, including two commercially available heteropolysaccharides—xanthan and gellan. As biodegradable and non-toxic fermentation products, xanthan and gellan have been successfully tested in various remediation techniques. Here, to highlight their prospects as green adsorbents for water decontamination, we have reviewed their biosynthesis machinery and chemical properties that are linked to their sorptive interactions, as well as their actual performance in the remediation of heavy metal contaminated waters. Their sorptive performance in native and modified forms is promising; thus, both xanthan and gellan are emerging as new green-based materials for the cost-effective and efficient remediation of heavy metal-contaminated waters.
Interest of improved three-point formulas for finite-difference modeling of optical devices

The accuracy of finite-difference computations is limited by the errors inherent in the classical three-point formula for ∂x2 (of order h2) and in the discretization of discontinuities in the refractive index (of order from h0 to h2). Various improvements are reviewed and analyzed, both for normal-mode derivations and for the beam propagation method (BPM). For the BPM it seems that sophisticated discretizations for discontinuities have a limited interest, whereas using a h4-accurate three-point formula for ∂x2 often allows the use of fewer grid points and hence faster computations; also it makes the operation of transparent boundaries with Berenger layers considerably more efficient. Finally, the permittivity should always be averaged mesh by mesh.
Scale correlation-based edge detection

This paper proposes an effective edge detection scheme based on the scale correlation in the wavelet transform that is equivalent to Canny edge detection. A correlation function is defined as the product of two adjacent wavelet subbands to magnify edges while filtering noise. Unlike many multi-scale techniques that form the edge maps on different scales and then synthesize them into a spatial edge map, our scheme detects edges as local maxima directly in the correlation function. The scheme totally avoids the potentially ill-posed synthesizing operation. The product of detection and localization criteria is higher than that of a single scale, which results in means better edge detection. The dislocation of neighboring edges is also improved. The performance of the presented scheme is illustrated by synthetic and natural images.
The science applications of the high-energy density plasmas created on the Nova laser

Since the late 1970s it has been realized that the laser‐heated hohlraums envisioned for indirect drive Inertial Confinement Fusion (ICF) could also serve as ‘‘physics factories’’ by providing a high‐energy density environment for the study of a wide variety of physics with important applications. In this review we will describe some of these studies, accomplished in the early 1990s using the Nova laser [J. T. Hunt and D. R. Speck, Opt. Eng. 28, 461 (1989)] at the Lawrence Livermore National Laboratory. They include measuring the opacity of Fe, thus confirming that the OPAL low Z opacity code [C. A. Iglesias and F. J. Rogers, Astrophys. J. 443, 460 (1995)] is quantitatively more accurate than ‘‘standard’’ models, with important astrophysical implications such as modeling the Cepheid variables [F. J. Rogers and C. A. Iglesias, Science 263, 50 (1994)]; measuring the Rosseland mean opacity of Au, confirming the correctness of the ‘‘Super Transition Array’’ (STA) high‐Z code [Bar Shalom et al., Phys. Rev. A 40, 3183 (1989)] with important implications for ignition targets designed for the National Ignition Facility (NIF); sophisticated Rayleigh–Taylor and other hydrodynamic turbulence experiments and analysis that serve as a test bed for understanding astrophysical observations such as supernova explosions; using laboratory x‐ray lasers for probing high‐density ICF plasmas as well as biology; and creating near Gbar pressures [Cauble et al. Phys. Rev. Lett. 70, 2102 (1993)]. Expanded opportunities for such research on the NIF will also be described.Since the late 1970s it has been realized that the laser‐heated hohlraums envisioned for indirect drive Inertial Confinement Fusion (ICF) could also serve as ‘‘physics factories’’ by providing a high‐energy density environment for the study of a wide variety of physics with important applications.

Approximation pricing and the variance-optimal martingale measure

Let X be a seminmartingale and Teta the space of all predictable X-integrable processes teta such that integral tetat dX is inthe space S square of semimartingales. We consider the problem of approximating a given random variable H element of L square (P) by the sum of a constant c and a stochastic integral of 0 to t with teta s and dXs, with respect to the L square (P)-norm. This problem comes from financial mathematics where the optimal constant V zero can be interpreted as an approximation price for the contingent claim H. An elementary computation yields V zero as the expectation of H under the variance-optimal signed Teta-martingale measure P~, and this leads us to study &Ptilde in more detail. In the case of finite discrete time, we explicitly construct P~ by backward recursion, and we show that P~ is typically not a probability, but only a signed measure. In a continuous-time framework, the situation becomes rather different: We prove that P~ is nonnegative if X has continuous paths and satisfies a very mild no-arbitrage condition. As an application, we show how to obtain the optimal integrand xi element teta in feedback form with the help of a backward stochastic differential equation.
Non- and semiparametric marginal regression models for ordinal response

We present a class of multivariate regression models for ordinal response variables in which the coefficients of the explanatory variables are allowed to vary as smooth functions of other variables. In the first part of the paper we consider a semiparametric cumulative regression model for a single ordinal outcome variable. A penalized maximum likelihood approach for estimating functions and parameters of interest is described. In the second part we explore a semiparametric marginal modeling framework appropriate for correlated ordinal responses. We model the marginal response probabilities and pairwise association structure by two semiparametric regressions. To estimate the model we derive an algorithm which is based on penalized generalized estimating equations. This nonparametric approach allows to estimate the marginal model without specifying the entire distribution of the correlated response. The methods are illustrated by two applications concerning the attitude toward smoking restrictions in the workplace and the state of damage in a Bavarian forest district.
The C/+/-CO transition in interstellar clouds

Ionized carbon recombines as the ultraviolet radiation field is attenuated inside interstellar clouds. It is proposed that C(+) is transformed into CO, the CO being formed by ion-molecule reactions of C(+) with OH and H2O. The characteristic column density of hydrogen required for the transition is approximately 3 sextillion per sq cm. The C(+)-CO transition has important implications for observations of CO and the thermal properties of sufficiently thick clouds.
