REMOTE WORK: TECHNOLOGIES AND EXPERIENCE OF THE ORGANIZATION
The types of remote employment (distance work and freelance) have been considered. Directions of use of modern information technologies at the organization of remote employment have been indicated and their developed characteristic has been given. The activity of freelancers has been described in detail. The mechanisms of functioning of international online labor exchanges and Russian platforms have been revealed. The results of a study on the practice of remote work in modern domestic organizations have been adduced. According to the results of the study, conclusions have been made about the areas of remote employment, its advantages and disadvantages for the organization and employees; about the software and hardware used by employers; about the problems of regulatory regulation of remote employment; about the competencies of remote workers and freelancers
A new approach to electromagnetic wave tails on a curved spacetime
We present an alternative method for constructing the exact and approximate
solutions of electromagnetic wave equations whose source terms are arbitrary
order multipoles on a curved spacetime. The developed method is based on the
higher-order Green's functions for wave equations which are defined as
distributions that satisfy wave equations with the corresponding order
covariant derivatives of the Dirac delta function as the source terms. The
constructed solution is applied to the study of various geometric effects on
the generation and propagation of electromagnetic wave tails to first order in
the Riemann tensor. Generally the received radiation tail occurs after a time
delay which represents geometrical backscattering by the central gravitational
source. It is shown that the truly nonlocal wave-propagation correction (the
tail term) takes a universal form which is independent of multipole order. In a
particular case, if the radiation pulse is generated by the source during a
finite time interval, the tail term after the primary pulse is entirely
determined by the energy-momentum vector of the gravitational field source: the
form of the tail term is independent of the multipole structure of the
gravitational source. We apply the results to a compact binary system and
conclude that under certain conditions the tail energy can be a noticeable
fraction of the primary pulse energy. We argue that the wave tails should be
carefully considered in energy calculations of such systems.Comment: RevTex, 28 pages, 5 eps figures, http://www.tpu.ee/~tony/texdocs/, 4

CONFLICTS՚ SOURCES AND STRESSFUL FACTORS IN MODERN ORGANIZATIONS
The article gives the results of a study of managers and ordinary employees of Russian organizations on the problem of identifying sources of conflicts and stress factors affecting the functioning of companies. The paper analyses in detail and presents the answers of respondents to the questionnaire about the frequency of the confrontation; on the impact of collisions on staff productivity and on the development of unfavorable mental states of workers; on the role of management and ordinary employees in the emergence of conflicts; about the main reasons for the conflict confrontation; on the system of conflict and stress management, including measures to prevent and resolve them. The results of the survey showed that both the company’s management and ordinary personnel are involved in conflicts, and the leading source of confrontation, according to the majority of respondents, is the individual psychological characteristics of employees. At the same time, the conflicts themselves act as stress factors, having a direct adverse effect on the efficiency of activities and causing specific unwanted emotional reactions. Among other things, the results of the survey showed that the organizations where the respondents work do not have a well-functioning system of conflict management. The research results are practice-oriented
SOCIAL DEVELOPMENT OF PERSONNEL IN THE CONDITIONS OF INNOVATIVE ECONOMY AS A FACTOR OF INCREASING THE LEVEL OF LIFE QUALITY
The importance of the social development of personnel in innovative economy as a decisive factor in the stability of society and improving the quality of life of both workers themselves and the entire population of the country has been defined. It has been shown that social development of staff in the organization contributes to the improvement of social and labor relations through interaction of the parties of social partnership based on the principle of tripartite cooperation and “tripartism”, and also contributes to the full development of the potential of employees and their professional competences. The main directions of social development of personnel included in the social policy of the organization have been determined in the paper. As a result of the research, priority role of cash payments and guarantees in the organization’s social responsibility strategy have been identified. At the same time, the main principle in the development of policy aimed at social development of staff should be targeted consideration of the needs of employees. The principle of targeting to determine the level of staff satisfaction should be the main one for evaluating the effectiveness of work in this direction. In addition, the authors point to the need to use modeling and forecasting the prospects of social innovations in order to achieve sustainable development in the long term

Wind and trophic status explain within and among‐lake variability of algal biomass
Phytoplankton biomass and production regulates key aspects of freshwater ecosystems yet its variability and subsequent predictability is poorly understood. We estimated within‐lake variation in biomass using high‐frequency chlorophyll fluorescence data from 18 globally distributed lakes. We tested how variation in fluorescence at monthly, daily, and hourly scales was related to high‐frequency variability of wind, water temperature, and radiation within lakes as well as productivity and physical attributes among lakes. Within lakes, monthly variation dominated, but combined daily and hourly variation were equivalent to that expressed monthly. Among lakes, biomass variability increased with trophic status while, within‐lake biomass variation increased with increasing variability in wind speed. Our results highlight the benefits of high‐frequency chlorophyll monitoring and suggest that predicted changes associated with climate, as well as ongoing cultural eutrophication, are likely to substantially increase the temporal variability of algal biomass and thus the predictability of the services it provides
Adaptation of persons with disabilities to inclusive education in the university as a condition of their successful functioning in the labour market
The main way to implement this principle of equality in the education of persons with disabilities and persons with disabilities (HIA) is now inclusive education at all levels of education throughout life. The basic concepts related to disability, integration of persons with disabilities into society, educational environment have been highlighted in the article, the differences in the understanding and interpretation of these concepts have been shown. The factors of adaptation of students with invalidity and disabilities have been disclosed. The formation of an inclusive educational environment in the University is impossible without improving the management of inclusive education in higher education system
Toward an optimal search strategy of optical and gravitational wave emissions from binary neutron star coalescence
Observations of an optical source coincident with gravitational wave emission
detected from a binary neutron star coalescence will improve the confidence of
detection, provide host galaxy localisation, and test models for the
progenitors of short gamma ray bursts. We employ optical observations of three
short gamma ray bursts, 050724, 050709, 051221, to estimate the detection rate
of a coordinated optical and gravitational wave search of neutron star mergers.
Model R-band optical afterglow light curves of these bursts that include a
jet-break are extrapolated for these sources at the sensitivity horizon of an
Advanced LIGO/Virgo network. Using optical sensitivity limits of three
telescopes, namely TAROT (m=18), Zadko (m=21) and an (8-10) meter class
telescope (m=26), we approximate detection rates and cadence times for imaging.
We find a median coincident detection rate of 4 yr^{-1} for the three bursts.
GRB 050724 like bursts, with wide opening jet angles, offer the most optimistic
rate of 13 coincident detections yr^{-1}, and would be detectable by Zadko up
to five days after the trigger. Late time imaging to m=26 could detect off-axis
afterglows for GRB 051221 like bursts several months after the trigger. For a
broad distribution of beaming angles, the optimal strategy for identifying the
optical emissions triggered by gravitational wave detectors is rapid response
searches with robotic telescopes followed by deeper imaging at later times if
an afterglow is not detected within several days of the trigger.Comment: 6 pages, 1 figure, Accepted for publication in MNRAS Letters (2011

A study of methyl formate in astrochemical environments
Several complex organic molecules are routinely detected in high abundances
towards hot cores and hot corinos. For many of them, their paths of formation
in space are uncertain, as gas phase reactions alone seem to be insufficient.
In this paper, we investigate a possible solid-phase route of formation for
methyl formate (HCOOCH3). We use a chemical model updated with recent results
from an experiment where simulated grain surfaces were irradiated with 200 keV
protons at 16 K, to simulate the effects of cosmic ray irradiation on grain
surfaces.
We find that this model may be sufficient to reproduce the observed methyl
formate in dark clouds, but not that found in hot cores and corinos.Comment: 6 pages, 2 figures, 2 tables Accepted by MNRA
