Abstract

The purpose of this chapter is to determine the level of readiness of the Russian society for information economy’s formation. For the formation of information economy, the authors use the methods of classification and structural analysis, as well as the proprietary method of criterial evaluation of society’s readiness. This method envisages structuring of population according to the main criteria: territory of residence (geographical criterion), age, level of education, level of income, and susceptibility to innovations (adaptation criterion). Based on the statistical data on readiness of various social categories for information economy’s formation and the share of these categories in the structure of population, the index of society’s readiness for information economy’s formation is calculated. The authors perform criterial evaluation of readiness of the modern Russian society for information economy’s formation as of 2017 and compile the model of the modern Russian society, structured according to the criterion of readiness for information economy’s formation. As a result, they conclude that information economy’s formation could face unreadiness of society, which is a serious barrier on the path of implementation of this process. During evaluation of the level of society’s readiness for information economy’s formation, it is expedient to structure it as per the five main criteria: territory of residence (geographical criterion), age, level of education, level of income, and susceptibility to innovations (adaptation criterion). The received structure of society allows compiling general impression on readiness for information economy’s formation of representatives of various social categories. The example of modern Russia could be the basis for similar evaluation of the level of society’s readiness for information economy’s formation in other countries of the world. This will allow developing and conducting more effective state social policy, which is directed at target influence on representatives of various social categories in the interests of increase of their readiness for information economy’s formation.

The purpose of this paper is to propose a fuel‐optimal virtual centre selection method for formation flying maintenance in the J2 perturbed environment.

Abstract

Purpose

The purpose of this paper is to propose a fuel‐optimal virtual centre selection method for formation flying maintenance in the J2 perturbed environment.

Design/methodology/approach

Based on the relative orbital elements (ROE) theory, the J2 perturbed relative motions between different satellites in the formation are analyzed, and then the fuel‐optimal virtual centre selection issue for formation flying maintenance are parameterized in terms of ROE. In order to determine the optimal virtual centre, two theories are proposed in terms of ROE.

Findings

Numerical simulations demonstrate that the fuel‐optimal virtual centre selection method is valid, and the control of the ROE of each satellite with respect to a virtual optimal centre of the formation is more efficient regarding the fuel consumption than the control of all satellites with respect to a satellite belonging to the formation.

Research limitations/implications

The fuel‐optimal virtual centre selection method is valid for formation flying mission whose member satellite in circular or near circular orbit.

Practical implications

The fuel‐optimal virtual centre selection approach can be used to solve formation flying maintenance problem which involves multiple satellites in the formation.

Originality/value

The paper proposes a fuel‐optimal virtual centre selection method in terms of ROE, and shows that keeping the formation with respect the optimal virtual centre is more fuel efficient.

Abstract

Purpose

Hill equations have definite limitation in the design of multiple spacecraft formation flying in eccentric orbits. To solve the problem, the design method of spacecraft formation flying in a circular reference orbit based on Hill equation can be generalized and applied to spacecraft formation flying in eccentric orbits.

Design/methodology/approach

In this paper, T‐H equation is expressed as the explicit function form of reference orbit true anomaly, and the state transition matrix of relative motion of spacecraft formation flying in eccentric orbits is derived. According to the requirement that relative dynamics equation of spacecraft formation flying in eccentric orbits has periodicity solution, the paper theoretically gives the initial condition needed by the long‐term close‐distance spacecraft formation flying including the relationship between relative position and relative velocity. Without perturbation the spacecraft formation, which satisfies the initial periodicity restriction, can keep long‐term close‐distance flying without the need of active control.

Findings

Based on the theoretical analysis, some numerical simulations are carried out. The results demonstrate that each spacecraft in eccentric orbits can run in a periodic motion surrounding the center spacecraft under some conditions. And spacecraft formation reconfiguration is implementing according to missions.

Originality/value

Combined with the periodicity restriction primary condition a new method about spacecraft formation reconfiguration is put forward. The method given by this paper can be applied to eccentric orbits of arbitrary eccentricity, and provides theoretical reference for orbit design of spacecraft formation flying in eccentric orbits.

Abstract

Purpose

This study investigates the long-run relationship between workers' remittances and human capital formation in Sri Lanka by using the macro-level time series data during the period of 1975–2020.

Design/methodology/approach

In this study, the augmented Dickey–Fuller (ADF) and Philips–Perron (PP) unit root tests, the autoregressive distributed lag (ARDL) bounds cointegration technique, the Granger causality test, the forecast error variance decomposition technique and impulse response function analysis were employed as the analytical techniques.

Findings

In accordance with the results of unit root tests, the variables used in this study are mixed order. Results of cointegration confirm that workers' remittances in Sri Lanka have both long-run and short-run beneficial relationship with human capital formation. The Granger causality test results indicate that there is a two-way causal relationship between workers' remittances and human capital formation. The results of forecast error variance decomposition expose that innovation of workers' remittances contributes to the forecast error variance in human capital in bell shape. Further, the empirical evidence of impulse response function analysis reveals that a positive standard deviation shock to workers' remittances has an immediate significant positive impact on human capital formation in Sri Lanka for a period of up to ten years.

Practical implications

This research provides insights into the workers' remittances in human capital formation in Sri Lanka. The findings of this study provides evidence that workers' remittances help to produce human capital formation.

Originality/value

By using the ARDL Bounds cointegration and other techniques in Sri Lanka, this study fills an important gap in academic literature.

Abstract

Purpose

Contemporary service and marketing research on value co-creation and value co-destruction assume a one-dimensional view on value, ranging from positive value co-creation, alignment and high value to negative value co-destruction, misalignment and low value. This limitation has recently led researchers to conceptually develop more dynamic spatial-temporal models of how value is formed during the interaction, e.g. in terms of different relationships between practice elements (procedures, understandings and engagements) both within and between actors in “value formation spaces”. However, much of this research awaits validation and is in need of more details. This study aims to address this limitation with the purpose of detailing how and why the mechanisms in such spaces are formed.

Design/methodology/approach

Two different and interlinked typologies were analytically derived from previous research and applied on ethnographically-inspired multi-perspective empirical data from a service combining health care and transport service ecosystems, using a combination of interviews, observations and service design methodologies. The design in combination with a practice theory perspective was used to articulate crucial aspects related to understanding the dynamics of value co-formation for elaborative and illustrative purposes.

Findings

The study contributes to service theory by conceptualizing as follows: a typology consisting of nine different configurations of practice elements (within and between such elements) and eight possible directions that value formation can take, suggesting a theory that explains value co-creation, value co-destruction and mixed cases.

Research limitations/implications

Although the findings have been developed in a specific empirical context, they articulate a conceptualization applicable to many other service and marketing value co-formation settings.

Practical implications

The typologies are conceptual tools to be used in identifying and measuring the alignment/misalignment of practice elements in complex organizations. The empirical findings uncover service problems faced by disabled customers.

Originality/value

The suggested typologies can guide research and practitioners in understanding and analysing value co-formation mechanisms in complex service settings.

The aim of this paper is to analyse the relationship between public debt, corporate debt service costs and private capital formation in South Africa.

Abstract

Purpose

The aim of this paper is to analyse the relationship between public debt, corporate debt service costs and private capital formation in South Africa.

Design/methodology/approach

To capture the long-run characteristic of investment, the study adopts the Fully Modified Ordinary Least Squares approach and tests for cointegration using Hansen (1992)'s Parameter Instability test.

Findings

We find that private capital formation increases in domestic debt and decreases in external debt during the pre-crisis period. However, during the period post the Global Financial Crisis, we find evidence of domestic public debt crowding out private capital formation, whereas external debt crowds-in capital formation. Debt service costs are found to reduce investment due to the effect of the debt overhang throughout the period under analysis.

Research limitations/implications

The paper has important implications for macroeconomic policy. In particular, there is need for deleveraging and allocation of a higher proportion of debt to public infrastructure expenditure which has complementary effects on private investment.

Practical implications

Debt overhang signal that South African firms could be over-leveraged, which hinders future growth prospects. Firms that face high levels of debt should consider debt restructuring.

Originality/value

Empirical studies undertaken to explore this relationship have yielded contradicting results suggesting that the relationship between public debt and private investment is heterogeneous depending on a given economy or prevailing macroeconomic environment. In particular, existing research does not provide evidence on whether recent increases in public debt in South Africa have led to crowding-in or crowding-out of private investment. This paper therefore contributes to empirical literature on the impact of public debt on private investment within a small open economy.

Abstract

Innovation project development is becoming more important in boosting competitiveness of universities and enterprises. It will not be possible to ensure rapid economic growth of enterprises without competitive innovations and without their introduction into education and business practice. The object of the research paper is innovations in teaching entrepreneurship. The subject of the research paper is analysis of the effective entrepreneurship education at the universities. The objective of the research paper is to study the integration process of technological business environment (TBE), intellectual capital (IC) formation, innovation project (IP) development at the universities and enterprises.

The tasks advanced in order to reach the objective: to identify the concept of IC, IP, the methodology of IP development at the universities, their main actions and methods; to carry out analysis of the TBE in Latvia, indicators characterizing it environment, the factors of TBE influencing IC, IP development at the universities and enterprises; to estimate the IP development as the teaching method at the universities and business practice in Latvia. The research period is from the year 2007 till the year 2020. This is the first research on the analysis of indicators of TBE influencing IC formation, IP development at the universities; the efficiency of involvement of academic staff in the formation of IC and IP development into entrepreneurship education in Latvia; definition of the IP development as the teaching method and presentation of its theoretical and practical interpretation.

Abstract

Purpose

This paper investigates the importance of team formation in entrepreneurship education, and the authors ask: how do different team formation strategies influence teamwork in higher education experiential learning-based entrepreneurship courses?

Design/methodology/approach

Employing a multiple case study design, the authors examine 38 student teams from three different entrepreneurship courses with different team formation paths to uncover potential links between team formation and learning outcomes.

Findings

The authors find that team formation mode matters. Randomly assigned teams, while diverse, struggle with handling uncertainty and feedback from potential stakeholders. In contrast, student self-selected teams are less diverse but more robust in handling this pressure. Results suggest that in randomly assigned teams, the entrepreneurial project becomes the team's sole reference point for well-being. Seeking to protect the project, the team's ability to deal with uncertainty and external feedback is limited, stifling development. In student self-select teams, team well-being becomes a discrete reference point. This enables these teams to respond effectively to external project feedback while nurturing team well-being independently.

Originality/value

Education theories' implications about the benefit of team diversity may not apply to experiential learning-based entrepreneurship education's typical level of ambiguity and uncertainty. Therefore, educators may have to reconsider the unique dynamics of team formation strategies to ensure strong teamwork and teamwork outcomes.

Abstract

We outline an economic theory of choice of organizational form, concentrating on explaining the selection of contractual relations within employee-owned firms. We then test the theory on a new database of U.S. producer cooperatives and find that the theory is largely supported by the data. Our principal conclusion is that producer cooperative formations have been rather strongly responsive to variations in economic conditions. While procyclical theories are clearly rejected, countercyclical theories receive considerable support. Neither political motivations nor legal institutions, especially the existence of cooperative incorporation laws, appear to have accounted for a portion of cooperative formations on a systematic basis. Support organizations have significant positive impacts on the formation rate of new cooperatives.

The purpose of this study is to explain the rapid growth of urban residents' sugar consumption in China from the perspective of habit formation.

Abstract

Purpose

The purpose of this study is to explain the rapid growth of urban residents' sugar consumption in China from the perspective of habit formation.

Design/methodology/approach

Using the provincial panel data of Chinese urban households from 1995 to 2012, this study uses the two-step System Generalized Moment Method (GMM) to test the habit formation effect on residents' sugar expenditure in urban China. We also use system GMM and the recursive estimated method to explore the changes of the habit formation coefficients in different years.

Findings

We find a significant habit formation effect on overall residents' sugar expenditure and different types of sugary foods expenditure. The habit formation effect on total residents' sugar expenditure and different types of sugary foods is decreasing over the years. The patterns of the changes of the habit formation effect on different types of sugar foods are slightly different.

Research limitations/implications

Due to data limitations, we are not able to do household-level analysis and to examine the heterogeneity of the habit formation effect.

Originality/value

This is the first study that examines changes in the habit formation effect on residents' sugar expenditure in urban China. Our findings provide a reasonable explanation for the rapid growth of residents' sugar consumption in urban China. The result helps to formulate targeted policies for future interventions to control the growth of sugar consumption.
