Determination of the Average Specific Capital Consumptions of CCPP with Gas Turbine of 30-125 MW and Put into Operation at TPPs of the Russian Federation from 2015 to the First Quarter of 2021

Research was carried out on the volume of gas turbine commissioning in the range of unit capacities of 30–125 MW at TPPs of the Russian Federation operating as part of a CCPP in the period from 2015 to the first quarter of 2021. The purpose of the research was to determine the average specific capital investment in construction and the average specific fuel consumption for the supply of electricity and heat for the CCPP introduced over the years in the united energy systems of the Russian Federation. Gas turbines are classified by electrical capacity into three groups: from 100 to 125 MW, from 60 to 99 MW and from 30 to 59 MW. An assessment of the quantitative distribution of gas turbines over the interconnected energy systems of the Russian Federation has been carried out. The results of the comparison of the quantitative commissioning of gas turbines are shown in the period from 2010 to the economic crisis of 2014 and in the period from 2015 to the present. A preliminary estimate of the increase in average specific capital investments in the construction of CCPP, which included gas turbines of the same electric power, was made for these periods.

Bourdieu’s Field Theory and Science Education: Possible Articulations and Appropriations

Based on contributions from the sociology of science in the field of Science Education, this article aims to explore and elucidate the concept of fields, formulated by Pierre Bourdieu, in the objects of study of this area. This theoretical study is structured in three parts, which are articulated throughout the text: a synthesis of the general and invariable principles of fields; an elaboration of an analogy between the different field theories (sociology and physics); a discussion about the appropriation of field theories in research studies on Science Education that use them. We discuss the field as a social space, the agents’ habitus, the positions in the field, disputes and interests, distribution of the specific capital, limits, boundaries, and the field autonomy. An interpretation of this complex Bourdieusian concept was defended, in a way to determine the limits of the field and their agents, based on how research has appropriated it. Therefore, a theoretical framework was advanced, coming up with the possible and effective articulations between Science Education and Bourdieu’ Sociology of Science.

Planning the organization's personnel needs as the initial stage of the HR policy and HR planning process

In the context of modern economy and digital transformation of the system of public relations, reconsidering the role and place of a person in an organization, the attitude to a person as an individual has changed dramatically. The processes of successful planning of the organization's personnel requirements are connected and involve obtaining answers to certain questions, including: how many employees will be required; employees of what qualifications will be required; when and where employees will be required; how and in what way to attract the necessary employees; how to better use employees in accordance with their knowledge, skills, abilities and their internal motivation; how and in what way to organize and provide conditions for the training and development of employees; how to implement the processes of using and laying off redundant employees; what costs or expenses will be necessary for the implementation of planned activities related to personnel requirements, and many other questions. Recently, any modern organization has increasingly linked its activities and its development with a specific capital – human capital. The article deals with the provisions related to the planning of personnel (human resources) and certain aspects of such planning, in particular, planning the organization's need for personnel for a certain planning period for its development and implementation of the intended indicators and plans. The materials of the article can be used within the "Economics and Management" and "Management" program tracks.

Digital capital and online activities: An empirical analysis of the second level of digital divide

This paper explores inequalities in using the Internet by investigating several digital activities that require different levels of digital capital. Data collected in the U.K. through an online survey of a national representative sample (868 respondents) shows that levels of digital capital and type and quality of online activities are intertwined. The analysis shows that digital capital, conceived and measured as a specific capital, is entangled with the frequency/intensity of social, economic/financial means, ordinary/daily entertainment, and political activities, but not with learning-related activities. This work contributes to the literature in both empirical and theoretical terms by testing the reliability of digital capital and expanding its use to investigate digital inequalities. From a policy-making point of view, the awareness of citizens’ level of digital capital may help tailor initiatives to support citizens in using ICTs on a wide array of fields, such as job seeking, sociability, savings, familial relationships, and several online activities. Finally, this paper highlights that digital inequalities cannot be tackled by considering access and competence separately. By contrast, the adoption of measures that synthesise the two dimensions might help simplify policy-making’s initiatives to tackle digital inequalities.

The effectiveness of the investment process of reproduction

The article analyzes the effectiveness of the investment process in Russian economy, which is assessed using indicators of specific capital investments for introduction of production capacities. The dynamics and characteristics of changes in specific capital investments for various types of economic activity of Russian industry are analyzed. The main groups of factors that determine the change in specific capital investments are identified. It is concluded that, in the medium term, the state of the economy with a significant share of extractive industries will continue to have a decisive influence on the dynamics of specific capital investments, and objective processes of depletion of the mineral resource base and worsening production conditions will increase specific capital investments. The continuation of the noted trends will determine the requirements for the volume and structure of investments to ensure the reproduction of the industrial potential and increase its technical and technological level.

Recovering Forecast Distributions of Crop Composition: Method and Application to Kentucky Agriculture

This paper proposes a novel application of the multinomial logit (MNL) model using Cropland Data Layer and field-level boundaries to estimate crop transition probabilities, which are used to generate forecast distributions of total acreage for five major crops produced in the state of Kentucky. These forecasts distributions have a wide range of applications that, besides providing interim acreage estimates ahead of the June Acreage Survey, can inform the ability of producers to incorporate new crops in the land-use rotation, investments in location-specific capital and input distribution as well informing the likelihood of adverse water quality events from nutrient run-off.

Rural-urban migrants’ remittances and wage inequality: Evidence from China

There is a link between rural-urban remittances and wage inequality. However, the existing literature sheds little light on this topic. In this study, we establish a three-sector general equilibrium model to investigate the effects of rural-urban migrants’ remittances on wage inequality. Further, we use Chinese macroeconomic data to calibrate the parameters and conduct analysis with numerical simulation. We find that, when rural-urban migrants raise their remittance rate, wage inequality between skilled labour and the urban formal sector remains unchanged in the sector-specific capital case but narrows in the sector-mobile capital case. Moreover, in the sector-specific case, skilled and unskilled wage inequalities, w_SY and w_SZ, decrease at the same rate as the urban-rural wage inequalities, w_XY and w_XZ, respectively. In the mobile case, however, the former declines faster than the latter.

Efficiency wage, unemployment and tourism development: a theoretical analysis

Purpose International tourism has experienced a substantial growth during the second half of twentieth century. Tourism development can contribute substantially to the reduction of poverty problem by creating new employment opportunities. The purpose of this paper is to analyse the effect of tourism development on unemployment problem using an efficiency wage framework. Design/methodology/approach The authors developed a two-sector two-factor static competitive general equilibrium model of a less-developed open economy called South with an imported traded goods sector and with a non-traded tourism service sector, and with two factors, capital and labour. Labour is measured in efficiency unit; there exists unemployment in the labour market which is explained by the efficiency wage hypothesis. The authors also consider extensions of the basic model by introducing an exportable traded goods sector as well as sector-specific capital in the tourism sector. Findings The authors show that, with perfect intersectoral mobility of capital and with only one traded good, tourism development in South lowers unemployment rate and raises national income. However, this tourism development neither affects unemployment rate nor national income in South, in the mobile-capital model when there are two traded goods. When tourism sector uses sector-specific capital but capital is mobile between two traded goods sectors, tourism development keeps the unemployment rate unchanged but raises national income in South. Originality/value There exists a lot of debate about economic benefits of tourism development in a less-developed economy. A few works analyse the economic effects of tourism without developing formal models. However, no existing work analyses the effect on unemployment in an efficiency wage model. Although Harris–Todaro model is of relevance to explain unemployment in low-income countries, efficiency wage models are relevant for middle-income countries.
