Toxic organizational environment on the Italian and Russian enterprises: an inter-country comparison

The concept of the organizational toxicity, which is considered by authors to be the phenomena of social pollution, is based on the study and synthesis of research results on the destructive aspects of the culture and working environment inside the organization. Toxic elements of the organizational environment have a negative impact on employees and cause a deterioration in their health and well-being that ultimately leads to a decrease in the efficiency of the use of human resources, in particular, and financial losses as a whole. Thus, there is underestimated the social aspect of a negative impact of the organization's economic activities on psychosocial health at work. The given research deals with the issue of the organizational toxicity, ex- pressed in reducing the level of well-being and deterioration of physical and psychosocial health of workers caused by the economic activities of the company. The theoretical study has allowed us to formulate hypoth- eses about the toxic management practices and their negative impact on workers’ psychosocial health. An empirical study conducted by the authors in comparison between Russian and Italian companies has permit- ted to verify the given hypotheses: to examine in detail the nature of the organizational toxicity and to identify toxic elements of the socio-labour relations in the company. An important feature of the current research is studying the toxic elements of working environment from the employers and employees points of view. The comparative studies possess an increasingly important cognitive function in the development of theories of labour and the science of management, as well as their practical applications. Inter-country comparisons allow us to approach the problem from a more common position, to the disclosure mechanisms of action, as well as forms of manifestation of separate regularities in various socio-economic systems

Introduction of Smart Working in the Enterprises of Russia and Italy: Case Study

The article focuses on the issues of transformation of labour relations between employers and employees of Russian and Italian enterprises due to the processes of digitization which determine the possibility of introducing new technologies in the organization of labour. One of the objectives of the research presented in the article is to analyse the advantages and shortcomings of the new management philosophy, to assess the impact of its introduction into the organization of work on the employee well-being and the level of social pollution in the sphere of labour relations. The case study method was used in the framework of an integrated approach, and was supplemented with an analysis of the narratives of Italian and Russian employees of enterprises operating in the information services industry. A comparative analysis of the empirical data obtained by the authors revealed the similarities and differences in the conditions and processes related to the introduction of the smart working technology into the organization of labour. The authors identified the attitude of the smart personnel in both countries to the new managerial philosophy, as well as the factors adversely affecting the quality of their working life. The scientific contribution of the research is the study and evaluation of one of the emerging phenomena of the new labour economy, which is developing in 4.0 industry and leads to the emergence of new forms of labour relations. © 2020 IOP Publishing Ltd.

Dependences of thermoelectric properties on the thickness of thin films of indium doped lead telluride

Dependences of thermoelectric properties (the Seebeck coefficient S, the electric conductivity σ, the Hall coefficient RH, the carrier mobilityμ and the thermoelectric power P = S²·σ) on the thickness d (d = 10 – 255 nm) of thin films prepared by vacuum evaporation of indiumdoped PbTe crystals and subsequent condensation on (111) BaF₂ substrates were obtained. With decreasing thickness of films to d ≈ 40 nm, there is n- to p-type inversion of conduction which is related to a change in thermodynamic equilibrium conditions and partial reevaporation of lead and/or indium atoms. Extremes were found on the thickness dependences of properties at d₁ ≈ 20 nm which is indicative of hole gas quantization. In the range of thicknesses with n-type conduction there is a smooth change in thermoelectric properties with thickness which testifies to manifestation of classical size effect and is sufficiently well described in the framework of the Fuchs-Sondheimer theory

The role of timely rheumatoid arthritis treatment effectiveness control

Background. Regular assessment of rheumatoid arthritis (RA) activity is a key factor in therapy effectiveness improving. Aim. To prove that timely RA treatment control recommended by modern guidelines improves outcomes and reduce disability in real clinical practice. Materials and methods. Fourty patients with RA hospitalized at the University Clinical Hospital from January 2021 to January 2023 were included into a retrospective single-center study and divided into 2 groups. In the first group, RA activity was monitored after 3, 6, and 12 months, with therapy adjusted if necessary. In the second group, monitoring of RA activity was carried out after 12 months. The patients underwent clinical, laboratory and instrumental examinations (Tender Joint Count (TJC) and Swollen Joint Count (SJC), common blood test with differential white blood cell count, ESR, biochemical blood test, CRP, RF, ACCP, hands, feet and chest X-ray, ECG). RA activity was assessed using DAS28, CDAI, SDAI indices in both groups. Results. RA activity control after 12 months in patients of the first group regularly observed by a rheumatologist was better than in patients of the second group, who visited rheumatologist again only in 12 months. DAS28 decreased significantly, from 4.71±0.80 to 3.08±0.70 in the group with regular monitoring during the observation period. Remission or low activity was achieved by 75% of patients (5% remission and 70% low activity). Less dynamics was registered in patients of the second group: the initial DAS28 was 4.50±0.74, DAS28 after 12 months was 4.36±0.64, which corresponds to moderate activity. Low activity was achieved in 15% of patients, remission was not achieved in any patient. Conclusion. Strict adherence to the recommended terms for disease activity monitoring is necessary for successful RA treatment in real clinical practice

On a snow cover composition in the vicinity of the Verkhnekamsky Salt Deposit

The snow cover chemical composition was investigated on the territory of the Verkhnekamskiy potash-magnesium salt deposit in the zone of influence of atmospheric emissions of Berezniki Potash Mining Complex (Perm Region). The object of researches was the snow in this area. Features of specific pollutants contained in the emissions of these mine groups and their relationship with the air intake and following atmospheric deposition were examined. With regard for specific character of pollutants in the emissions, studies of melt water included determination of the following chemical components – SO42-, Cl-, NO3-, NO2-, НCO3-, Ca2+, Mg2+, Na+, K+, of the pH value as well as suspended solid substances, and total mineralization. An analysis of snow composition was performed on two sites from which one was the surrounding background territory, while another area was the urban territory of city Berezniki, i.e. area of operating mine group. To assess the results the indicator of specific stock macro component was used. Increased specific stock relative to the background snowpack is clearly indicative of components directly related to the extraction and processing of salts Cl-, Na+, K+. The revealed anomalies have a local character and, as a rule, do not extend beyond boundaries of sanitary protection zones of the enterprises. Maps of distribution of values of the specific reserves for the analyzed list of components in the melt water were constructed. Our results obtained for the Verkhnekamskiy Deposit area were compared with similar published data on the territories of cities in the zone influenced by motor roads, reserves, and coastal zones of the Russian Arctic seas

Динамика и корреляция данных рентгенологического и артроскопическогоисследования коленного сустава при ревматоидном синовите

Objective: to compare the data of knee joint X-ray and arthroscopic studies in the presence of rheumatoid synovitis. Subjects and methods. Sixty-seven patients who had undergone 72 arthroscopic synovectomic operations on 72 joints for chronic knee-joint synovitis in the presence of rheumatoid arthritis (RA) were examined. Preoperative knee-joint X-ray study was carried out with the standard projections in all the patients. In most cases, the magnitude of X-ray changes corresponded to grade 1 according to the Larsen classification. The degree of articular cartilage destruction was intraoperatively estimated. Repeated X-ray films were made 6 and 30-36 months after arthroscopy. Results. It has been fount that in 72,2% of cases, the true articular cartilage changes detectable by arthroscopic revision were ascertained to coincide in their magnitude with the X-ray changes determined by the Larsen classification or to exceed them. Conclusion. In knee-joint RA, arthroscopic revision can provide the fullest information on the severity of pathological changes; however, X-ray study aids to a certain degree in the prediction of arthroscopic findings, including those of articular cartilage pathology.Целью данного исследования явилось сравнение данных рентгенологического и артроскопического исследования коленного сустава на фоне ревматоидного синовита. Материал и методы. Обследовано 67пациентов, у которых на 72 суставах выполнено 72 операции артроскопической синовэкто-мии по поводу хронического синовита коленного сустава на фоне ревматоидного артрита (РА). В предоперационном периоде всем пациентам проводили рентгенографию коленных суставов в стандартных проекциях. Степень рентгенологических изменений в большинстве случаев соответствовала 1-й стадии по классификации Larsen. Во время операции оценивали степень разрушений суставного хряща. Повторные рентгенограммы выполняли через 6 мес и через 30-36 мес после артроскопии. Результаты исследования. Установлено, что в 72,2% наблюдений истинные изменения суставного хряща, выявляемые при артро-скопической ревизии, совпадают по тяжести с рентгенологическими изменениями, определяемыми по классификации Larsen, или превосходят их. Заключение. При РА коленного сустава данные артроскопической ревизии позволяют получить наиболее полную информацию о тяжести патологических изменений, однако рентгенологическое исследование в определенной степени помогает прогнозировать артроскопические находки, в том числе в отношении патологии суставного хряща

Dual visible and near-infrared luminescent silica nanoparticles. Synthesis and aggregation stability

Novel silica nanoparticles exhibiting near-infrared (NIR) and dual NIR-visible emission were synthesized according to reverse microemulsion procedure through the encapsulation of Yb(III) complex with p- sulfonatothiacalix[4]arene (Yb) and [Ru(dipy)3]Cl2 (Ru) as NIR- and visible-emitting luminophores into silica matrix. The synthesis was carried out at various Yb:Ru molar ratio. The numbers of Ru and Yb complexes per one nanoparticle were calculated from both fluorimetric and inductively coupled plasma atomic emission spectroscopy data. The dynamic light scattering measurements of aqueous dispersions of Yb, Ru, and Ru-Yb nanoparticles elucidate the relationship between the complexes inserted into nanoparticles and their aqueous dispersity. The transmission electron microscopy images were used to measure the size of the nanoparticles. The atomic force microscopy images reveal the different aggregation morphology of Yb- and Ru-doped nanoparticles. © 2010 American Chemical Society
