Professional Responsibility of Labor Subjects

The problem of the labor subjects’ responsibility is a challenging issue in the unstable conditions of the nowadays world and business. Within the organizational context, the professional responsibility is a regulator of the performance of assigned duties at work places, a standard of compliance with a job position or with the corporate culture requirements. А.R. Luria noted that the labor is the conscious development product of a subject, which means that restricting an employee to a job position or corporate standards may impoverish both an organization and its members. In this regard, the corporate and professional responsibility may have different consequences of the manifestation of the subjective position in solving complicated production tasks. This study proposes an integrated analysis of the professional responsibility of the labor subjects through three interrelated contexts: personal, cultural and activity-related; depending on the intensity level of these components, the labor subjects have a different level of professional responsibility. The purpose of this study is to analyze the specific features of the professional responsibility of employees in a Russian construction company depending on the axiological and situational determinants (159 people, the average age of therespondents is 36 years). Results: 1. A methodology was developed and tested that allowed identifying the situational determinants of professional responsibility (conceptions of the organizational reality in three temporal loci - past, present and future). 2. The leading role of the cognitive component is confirmed in the formation of the managerial type of responsibility. It is proved that this responsibility component is largely determined by situational characteristics: the conceptions of the professional and personal resources of the collective and the assessment of organizational reality. 3. The types of professional responsibility and their determinants are defined. Thus, the representatives of the impulsive and executive types are ”responsibility objects” (personal context), the carriers of the egocentric culture of professional responsibility (cultural context) and the incoherence of temporal loci. As opposedto them, the managerial type of responsibility is determined by the internal personal orientation (is an active subject) taking responsibility not only for oneself, but also for others (includes others in the culture of professional responsibility), as well as the ability for strategic thinking (which is manifested in consideration, at the same time, for the professional and organizational aspects of the past, present and future in the activities). The results obtained make the understanding of the professional responsibility mechanisms wider, allow developing managerial technologies to provide the personnel quality taking into consideration the professional responsibility and its dynamic multilevel nature; empirically substantiated is the significance of the cognitive component of responsibility (cognitive and reflexive resources). Identified are positive and negativesubjective assessments of organizational reality and their influence on the types of professional responsibility. Keywords: types of professional responsibility, relationship of responsibility components, determinants

Raising and lowering operators, factorization and differential/difference operators of hypergeometric type

Starting from Rodrigues formula we present a general construction of raising and lowering operators for orthogonal polynomials of continuous and discrete variable on uniform lattice. In order to have these operators mutually adjoint we introduce orthonormal functions with respect to the scalar product of unit weight. Using the Infeld-Hull factorization method, we generate from the raising and lowering operators the second order self-adjoint differential/difference operator of hypergeometric type.Comment: LaTeX, 24 pages, iopart style (late submission

Orthogonal polynomials of discrete variable and Lie algebras of complex size matrices

We give a uniform interpretation of the classical continuous Chebyshev's and Hahn's orthogonal polynomials of discrete variable in terms of Feigin's Lie algebra gl(N), where N is any complex number. One can similarly interpret Chebyshev's and Hahn's q-polynomials and introduce orthogonal polynomials corresponding to Lie superlagebras. We also describe the real forms of gl(N), quasi-finite modules over gl(N), and conditions for unitarity of the quasi-finite modules. Analogs of tensors over gl(N) are also introduced.Comment: 25 pages, LaTe

Features of Dynamics of Antivibration Mounts with Inertial Hydraulic Converter Subjected to Vibro-Impact Loading

Antivibration mounts with inertial hydraulic converter are widely used to protect a variety of technical systems from shock and vibration. As it follows from existing literature, models of such a mounts on the basis of mechanical and mechanical-electrical analogies instead of real hydro-mechanical system are usually used to study their dynamic properties and design. These models are not able to describe fluid dynamics in hydraulic mount, and are not suitable to study rapidly changing processes, which is especially required for effective application of the mounts at vibro-shock loading. In this work, a model of inertial hydraulic converter, which is a system of two hydraulic cylinders of unilateral operating principle, connected by a rigid hydraulic tube, is described. Dynamics of fluid in hydraulic converter is described by the Navier-Stokes equations for a compressible fluid and the equation of state of the fluid in assumption of its isentropic motion. The results of numerical simulation of antivibration mount dynamics at shock loading by using finite element package ANSYS/LS-DYNA are presented. It is found out that increasing the length of the tube and reducing the tube diameter lead to an increase in the transmitted dynamic force

Circulating Atherogenic Multiple-Modified Low-Density Lipoprotein: Pathophysiology and Clinical Applications

Low-density lipoprotein (LDL) circulating in human bloodstream is the source of lipids that accumulate in arterial intimal cells in atherosclerosis. In-vitro–modified LDL (acetylated, exposed to malondialdehyde, oxidized with transition metal ions, etc.) is atherogenic, that is, it causes accumulation of lipids in cultured cells. We have found that LDL circulating in the atherosclerosis patients’ blood is atherogenic, while LDL from healthy donors is not. Atherogenic LDL was found to be desialylated. Moreover, only the desialylated subfraction of human LDL was atherogenic. Desialylated LDL is generally denser, smaller, and more electronegative than native LDL. Consequently, these LDL types are multiply modified, and according to our observations, desialylation is probably the principal and foremost cause of lipoprotein atherogenicity. It was found that desialylated LDL of coronary atherosclerosis patients was also oxidized. Complex formation further increases LDL atherogenicity, with LDL associates, immune complexes with antibodies recognizing modified LDL and complexes with extracellular matrix components being most atherogenic. We hypothesized that a nonlipid factor might be extracted from the blood serum using a column with immobilized LDL. This treatment not only allowed revealing the nonlipid factor of blood atherogenicity but also opened the prospect for reducing atherogenicity in patients

Detection of New Variable DNA Loci That Distinguish Medievalis Biovar Strains of Plague Agent from the Strains of Other Biovars

Variable chromosome loci have been searched, that differentiate Yersinia pestis strains of medievalis from antiqua biovars. The strains of medievalis biovar are shown to possess two deletions – 183 and 70 bps. The first deletion, localized in the inter-gene region aceA – aceK is present in the majority of medievalis biovar strains, the second one, in the gene y1694 , is determined in all medievalis biovar strains isolated in the territory of Russia and neighboring countries

Magnetic vortex as a ground state for micron-scale antiferromagnetic samples

Here we consider micron-sized samples with any axisymmetric body shape and made with a canted antiferromagnet, like hematite or iron borate. We find that its ground state can be a magnetic vortex with a topologically non-trivial distribution of the sublattice magnetization $\vec{l}$ and planar coreless vortex-like structure for the net magnetization $\vec{M}$. For antiferromagnetic samples in the vortex state, in addition to low-frequency modes, we find high-frequency modes with frequencies over the range of hundreds of gigahertz, including a mode localized in a region of radius $\sim$ 30--40 nm near the vortex core.Comment: 20 pages, 1 figur
