This research aims to do the assessing the feasibility of the Public-Private Partnership project in investing in the construction of the Palu-Parigi By-pass road through a PPP financing scheme, thereby providing opportunities for the private sector to participate in the provision of special road infrastructure. In this context, experimental criteria for determining Value for Money (VFM) are applied using the PPP model, to evaluate projects. The main objective also emphasizes the provision of greater VFM Goods through private financing, through conventional methods that are economical, efficient and effective. Furthermore, financial performance measurement reports apply several methods, including Payback Period (PP), Net Present Value (NPV), and Internal Rate of Return (IRR) which determine the feasibility and time required for returns on invested capital. The previous Economic Feasibility Study of the Palu-Parigi By-pass Road Construction project also showed an EIRR value of 20.1% in 2014, illustrating the economic development of this work. In connection with the limitations currently faced by the Regional Budget Agency of Central Sulawesi Province, the next PPP scheme is recommended for road construction by prioritizing infrastructure completion after the 28 September 2018 earthquake and the COVID-19 pandemic. The DBFMT (Design–Build–Finance–Maintenance–Transfer) model was also applied to the project, with GCA responsible for design, construction, financing, periodic maintenance and transfer at the end of the collaboration agreement.

The purpose of the article is to present the results of analysis of newly industrialized countries in the context of sustainable development. The study took place within the framework of the Kaldor’s structural-economic model of the gross domestic product and the energy flow model, using the socio-economic systems power changes analyzing method. Within the context of the approach, an invariant coordinate system in energy units is considered, the necessary conditions for sustainable development are formulated, and the main parameters for assessing the potential for growth and development are determined. The article focuses on key issues regarding new concepts of sustainable development and methodology for assessing sustainable development using the concept of socioeconomics useful power for the countries of the newly industrialized economy a group of emerging countries that have made in short time period a qualitative transition in socio-economic development. Based on a new definition of sustainable development in energy units, development trends are formulated for the selected countries during 20 years for the period 2000–2019. Results of the study can be used to planning for the transition to sustainable development. The data of the Central Statistical Office of European Union, the World Bank and the United Nations Organization were used for calculations. Initial interpretation of the calculated data has been done for the largest newly industrialized countries Brazil, India and China in terms of the gross domestic product in the period 1990–2019. For comparison, data on USA are presented as countries with advanced economy.

The article examines the current state of fertility processes in Kazakhstan, the diversity of reproductive scenarios, and the reasons for their formation. The authors proceed by analysing the sovereign demographic system formed in Kazakhstan in the first quarter of the 21st century based on the Kazakh ethnic group. Cluster analysis was performed for demographic zones, considering indicators such as the proportion of Kazakhs in the urban population and the total fertility rate in cities. We believe that case technology allows us to demonstrate the differences in the reproductive attitudes and behaviour of urban Kazakhs, ultimately determining the trends in reproductive processes in the country. The focus is given to the socio-cultural and socio-economic differences across the regions of Kazakhstan and their impact on fertility processes in the context of the accelerated urbanisation of Kazakhs. The main variants of adaptation of the reproductive behaviour of Kazakhs to new urban living conditions are described, and an assumption is made about further prospects for maintaining or changing birth rates in Kazakhstan.

Public signs in scenic spots play the role of guidance, instruction and warning, and are of great significance to promote the development of scenic spots. Guang’an District has a strong historical and cultural heritage and the rapid development of tourism, but the English translation of public signs in the scenic spot has become increasingly prominent, mainly including nonstandard translation, spelling errors, logical confusion and grammatical errors. In order to promote the solution of such problems, this paper will analyze the current situation of English translation of public signs in Guang’an scenic spots, and put forward solutions to the problems of English translation of public signs through hiring professional translators, cultural difference training and regional cooperation.

The explosion of information technology, besides its positive aspects, has raised many issues related to personal information and personal data in the network environment. Because children are vulnerable to abuse, fraud and exploitation, protecting children’s personal information and personal data is always of concern to many countries. From the concept and characteristics of personal information and personal data of children in Europe, the United States and Vietnam, it can be seen that children’s personal information and personal data protection is very necessary in every country today. This research focuses on the age considered a child, the child’s consent and his or her parental consent when providing and processing personal information or personal data of children under the laws of the EU, US and Vietnam. Therefore, the article proposes some recommendations related to the child’s consent and his or her parental consent in protecting children’s personal data in Vietnam.

The subject of traditional institutions cannot be undermined in the project of sustainable leadership and good governance in Nigeria given the locus and crucial role of the institution in the past and modern Nigeria. It is incontrovertible that traditional and aboriginal values are held highly with reverence and respect in virtually all parts of Nigeria. To discountenance their relevance will be too costly in any leadership-cum-governance discourse. Towns, villages and cities were duly recognized and protected as the harbingers of culture, mores, norms and values. The contemporary government structure in Nigeria duly recognizes the importance of traditional institutions by having a Commission for Local Government (LG) and Chieftaincy Affairs at all State levels. Moreover, 5% of allocations to LGs go statutorily to the tradition institution in the State. Hitherto, the recklessness and abuse of the native authority system of local government administration in the 1950s–60s had led to the moderation and reforms of the system, which has continued to affect traditional institutions to date. To this end, the paper argues that traditional institutions hold so much values and cohesive practices as well as socially integrative potentials for nation-building so much that the State can leverage on them for sustainable leadership and overall good governance. The methodology adopted for collecting data for this study is descriptive research method, which relies on primary direct observation (eye-witness) account and relevant secondary materials such as texts, journal articles, official documents and internet materials. The data collected were analyzed and presented using thematic analysis and tables. National and international data already analyzed were found essential to drive home the argument of this study. The outcome of the paper provides useful information on how traditional institutions serve as a veritable platform for sustainable leadership and good governance in Nigeria. The paper concluded that traditional institutions, with its rich culture, values and practices, possess sufficient merits to propel the country towards sustainable leadership that would concomitantly induce economic, technological and political growth in Nigeria.
