In this review, we study the state of entrepreneurial education as it applies to business resilience. We consider records over the last 20 years about entrepreneurial resilience that consider their social impact and focus on sustainability. The aim of the study was to determine whether an enterprise that stresses social impact and sustainability rather than profits could reinforce entrepreneurial resilience. The importance of this study is that it offers a more complex description of entrepreneurial resilience by connecting social and environmental sensitivity with a profit-oriented logic. We found a mild incremental rise in, first, the years of the 2000s and a jump by 2010. We then used VosViewer to create a cluster map from the record list of WOS, creating three clusters of: “education and sustainability”, “entrepreneurship and social impact” and “innovation”, and these three clusters were related to superior entrepreneurial resilience. This approach should be adopted in real time to be able to adapt to socio-economic crises, adopting a functional approach based on cooperativeness and awareness of complexity.

RESUMOO artigo tem como objetivo analisar as principais características do estado fiscal, abordando uma perspectiva histórica sobre as atribuições do estado e a importância de arrecadar impostos como mecanismo de custeio das despesas estatais; bem como as repercussões que as crises econômicas acarretam na sustentabilidade do estado fiscal de diferentes formas, principalmente, na redução da arrecadação de impostos e no impacto social. A realidade dos países tem demonstrado que manter o atual modelo de estado fiscal, em um contexto econômico instável, exige grandes desafios diante das responsabilidades assumidas pelo setor público. PALAVRAS-CHAVES: Estado fiscal; Sustentabilidade; Crise econômica; Impacto social. ABSTRACTThis paper has the aim of analyzing the main characteristics of fiscal state, approaching a historical perspective about the attributions of the state and the importance of collecting taxes as a mechanism to financing state expenditures; as well as the repercussions that economic crises cause into the fiscal state sustainability in different ways, mainly in the reduction of tax collection and social impact. The reality of the countries has shown that maintaining the current fiscal state model, in unstable economic scenario, demands considerable challenges in front of the responsibilities taken by the public sector. KEYWORDS: Fiscal state; Sustainability; Economic crisis; Social impact.

Real-time monitoring of the economy is based on activity indicators that show regular patterns such as trends, seasonality and business cycles. However, parametric and non-parametric methods for signal extraction produce revisions at the end of the sample, and the arrival of new data makes it difficult to assess the state of the economy. In this paper, we compare two signal extraction procedures: Circulant Singular Spectral Analysis, CiSSA, a non-parametric technique in which we can extract components associated with desired frequencies, and a parametric method based on ARIMA modelling. Through a set of simulations, we show that the magnitude of the revisions produced by CiSSA converges to zero quicker, and it is smaller than that of the alternative procedure.

With the rapid development of satellite technology and the need to satisfy the increasing demand for location-based services, in challenging environments such as indoors, forests, and canyons, there is an urgent need to improve the position accuracy in these environments. However, traditional algorithms obtain the position solution through time redundancy in exchange for spatial redundancy, and they require continuous observations that cannot satisfy the real-time location services. In addition, they must also consider the clock bias between the satellite and receiver. Therefore, in this paper, we provide a single-satellite integrated navigation algorithm based on the elimination of clock bias for broadband low earth orbit (LEO) satellite communication links. First, we derive the principle of LEO satellite communication link clock bias elimination; then, we give the principle and process of the algorithm. Next, we model and analyze the error of the system. Subsequently, based on the unscented Kalman filter (UKF), we model the state vector and observation vector of our algorithm and give the state and observation equations. Finally, for different scenarios, we conduct qualitative and quantitative analysis through simulations, and the results show that, whether in an altimeter scenario or non-altimeter scenario, the performance indicators of our algorithm are significantly better than the inertial navigation system (INS), which can effectively overcome the divergence problem of INS; compared with the medium earth orbit (MEO) constellation, the navigation trajectory under the LEO constellation is closer to the real trajectory of the aircraft; and compared with the traditional algorithm, the accuracy of each item is improved by more than 95%. These results show that our algorithm not only significantly improves the position error, but also effectively suppresses the divergence of INS. The algorithm is more robust and can satisfy the requirements of cm-level real-time location services in challenging environments.

Green Entrepreneurship

The purpose of this study is to determine the main directions of development of green entrepreneurship on the basis of environmental responsibility. The relevance of this study is due to the need to identify the main directions of green business development to solve environmental problems, based on the basic principles of environmental responsibility. It is believed that environmental responsibility is the basic basis for the formation of socially responsible green entrepreneurship, whose mission is environmental improvement on the basis of sustainable development. It is established thatit is expedient to consider ecological responsibility on levels (the state, the enterprises, the public).As the experience of successful companies shows, environmental responsibility can be integrated into the value and business of the company.The analysis revealed the main tools to stimulate green entrepreneurship: environmental taxes, "green" investments, instruments of stimulating influence on green entrepreneurship. It is established that in Ukraine the main responsibility for the implementation of sustainable development lies with the state and enterprises. The research revealed shortcomings in the organization of supervision measures and control over the targeted use of funds for the implementation of environmental programs. Also the imperfection of the regulatory framework, the inefficiency of the accounting, reporting and monitoring system, the ineffectiveness of measuresmonitoring the results of each project within a specific program to solve environmental problems. It is established that local governments and enterprises are two important participants in the environmental management system in Ukraine. Therefore, it is important to regulate environmental responsibility at the national, including regional, and corporate levels.
