A Real Estate Early Warning System
The real estate market is vital for national economic development, and it is of great significance to research an early warning method to identify an abnormal status of the real estate market. There is the warning status of the Beijing real estate market went from a fluctuation status to a stable “Normal” status from 2000 to 2020, and the warning status is expected to be more stable under a “Normal” status in the next decade under the same political and economic environment. The PSO-LSSVR model was found to have accurate prediction ability and demonstrated generalization ability.

The Village Fund Program in Indonesia
This study analyzes the Indonesian Village Fund (VF) Program by mapping each VF-related activity to all 17 SDGs (Sustainable Development Goals), and then determines an SDG-based VF allocation in 2018, 2019, and 2020. This study used data from all villages in Indonesia and is the most comprehensive study in Indonesia to address the knowledge gap between VF allocation and SDGs by analyzing the distribution of the use of the VF. The objectives of this paper are: (1) to provide the extent of VF usage to provide evidence on whether this utilization was aligned with the targeted SDGs, and (2) to provide information regarding village activities funded by the VF that were linked to each SDG. The results from this analysis can be used to encourage the Government to socialize and provide an understanding of SDGs to village leaders. Moreover, since Indonesia has developed Village SDGs, which are based on national SDG targets and localization of global SDGs to adapt to local culture as well as social and environmental conditions, it is recommended that other developing countries could formulate similar strategies to help achieve their national SDG targets and to develop rural areas in a more targeted way by prioritizing the most relevant issues. The study shares lessons learned from Indonesian experience in managing fiscal policy to more than 70,000 autonomous villages through the village fund program in the last five years.

Forecasting a Stock Trend Using Genetic Algorithm
The performance of the model significantly outperforms the dummy forecast. In some cases, the accuracy of the model was up to 80%. The results also showed that S&P 500 (the US stock market) is the most useful stock index in the prediction on all sectors. This could be because the 15 considered stocks have been selected from NYSE and NASDAQ. In contrast, CAC40 (French stock index) seems to have the lowest impact on two out of the three sectors. Moreover, past historical data of the stock itself helps significantly in predicting its trend. However, the results also show that the accuracy of the model decreases considerably while trying to predict large price changes.

Management Research as Design Science
Design science (DS) approaches have been emerging in engineering, management and other disciplines operating at the interface between design research and the natural or social sciences. Based on a state-of-the-art review of how DS is applied by management researchers, we develop a DS methodology for design-oriented disciplines that tend to adopt a rather intuitive notion of theory.

Sustainable Finance and COVID-19
Both the GARCH models and the event study suggest that funds with a higher ESG rating were able to outperform other funds during the COVID-19 period. These funds had a greater level of resilience and exhibited a lower level of risk contagion during the pandemic. These instruments appear to assume the role of risk protection and should be considered a means of both promoting sustainable growth and minimizing portfolio risk.

Pension Information
A wide array of research has investigated the effects of pension information on different individuals’ economic outcomes. While many studies show that information provision increases knowledge, the evidence is mixed regarding its effects on behavior. Nevertheless, examining different studies, some conclusions can be elicited about the effects of pension information on three broad areas of economic behavior: retirement planning, labor supply, and savings decisions. Specifically, the provision of pension information not only increases workers’ knowledge about their benefits, but it also fosters individuals’ retirement planning and decision making. Looking at individuals’ labor supply, our review of the literature showed that only correctly informed workers are responsive to the incentives to work longer. Finally, information letters and other educational interventions such as seminars are found to increase both enrollment in retirement plans and the amount of contributions. We also highlight that the lack of knowledge prevalently hits the most vulnerable individuals in the society, such as women. As a consequence, not providing sufficient information could contribute to widening the gender gap in pensions.

Social Security
Social security is "any government system that provides monetary assistance to people with an inadequate or no income". In the United States, this is usually called welfare or a social safety net, especially when talking about Canada and European countries. Social security is asserted in Article 22 of the Universal Declaration of Human Rights, which states: In simple terms, the signatories agree that the society in which a person lives should help them to develop and to make the most of all the advantages (culture, work, social welfare) which are offered to them in the country. Social security may also refer to the action programs of an organization intended to promote the welfare of the population through assistance measures guaranteeing access to sufficient resources for food and shelter and to promote health and well-being for the population at large and potentially vulnerable segments such as children, the elderly, the sick and the unemployed. Services providing social security are often called social services. Terminology in this area is somewhat different in the United States from in the rest of the English-speaking world. The general term for an action program in support of the well being of poor people in the United States is welfare program, and the general term for all such programs is simply welfare. In American society, the term welfare arguably has negative connotations. In the United States, the term Social Security refers to the US social insurance program for all retired and disabled people. Elsewhere the term is used in a much broader sense, referring to the economic security society offers when people are faced with certain risks. In its 1952 Social Security (Minimum Standards) Convention (nr. 102), the International Labour Organization (ILO) defined the traditional contingencies covered by social security as including: People who cannot reach a guaranteed social minimum for other reasons may be eligible for social assistance (or welfare, in American English). Modern authors often consider the ILO approach too narrow. In their view, social security is not limited to the provision of cash transfers, but also aims at security of work, health, and social participation; and new social risks (single parenthood, the reconciliation of work and family life) should be included in the list as well. Social security may refer to: A report published by the ILO in 2014 estimated that only 27% of the world's population has access to comprehensive social security.

Stakeholders in Managing a Safe City
Contemporary cities are complex systems in which there are many interactions and dependencies in relation to the environment. Currently, the development of cities and their safety are among the most important international socio-economic processes. The movement of people to larger agglomerations from smaller towns creates a variety of relationships between actors and often leads to very complicated lives in urban space. Features of contemporary cities include urbanization, personal development opportunities, labor markets, and infrastructure, as well as technological and cybernetic networks that optimize all the processes taking place in agglomerations. It should be emphasized that the main goal of public management in urban space is to create various solutions in the field of safety and thus to improve the quality of. In this respect, the role and influence of stakeholders on the processes of smart and safe city development are important. At each stage of activity, the City Council, local communities, economic entities, scientific institutions, and municipal enterprises are important for a city’s safety.

Agrivoltaics in Ontario Canada
Well-intentioned regulations to protect Canada’s most productive farmland restrict large-scale solar photovoltaic (PV) development. The recent innovation of agrivoltaics, which is the co-development of land for both PV and agriculture, makes these regulations obsolete. Burgeoning agrivoltaics research has shown agricultural benefits, including increased yield for a wide range of crops, plant protection from excess solar energy and hail, and improved water conservation, while maintaining agricultural employment and local food supplies. In addition, the renewable electricity generation decreases greenhouse gas emissions while increasing farm revenue.  The background on Ontario land-use Policy and policy recommendations about agrivoltaics are discussed.
