A cross country analysis of financial development, trade openness, population and digitalization’s impact on sustainable development

This study employs the Standard Error Estimation technique to investigate the connections between the digitalization of economy, population, trade openness, financial development, and sustainable development across 127 countries from 1990 to 2019. The findings revealed associations between financial development, population growth, trade openness, economic growth, Digitalization development, foreign direct investment (FDI), and sustainable development. Financial development negatively impacts sustainable development, suggesting that countries with advanced financial systems may struggle to maintain sustainability. Trade openness exhibits a negative association with sustainable development, implying that countries with open trade policies may face challenges in maintaining sustainability, possibly due to heightened competition or resource exploitation. These findings highlight the multifaceted relationship between economic factors and sustainable development, underscoring the importance of comprehensive policies and governance mechanisms in fostering sustainability amidst global economic dynamics.

Modeling and simulation of liquid metal battery (LMB) materials development using statistical package for social sciences (S.P.S.S.)

There are a number of input parameters that are considered in relation to the stimulatory possibility of constructing a Liquid Metal Battery (LMB). This paper talks about the modeling approach possible for use in LMB research work. Equivalent Circuit Modeling (ECM) is the most common method used to analyze input data or parameters. In analyzing some of the basic elements, such as electrical capacitance, electrical resistance, open circuit voltage, terminal voltage, temperature, time response, time constants, State of Charge (SOC), etc., the cell impedance could be calculated by predicting the system elements that would play key roles in the determination of the parameter identification method for the battery’s Equivalent Circuit Model. Secondly, each element in the model has a known behaviour, which mainly depends on the element type and the values of the parameters that characterize that element. In EIS software, the Graphical Model Editor could be used to build an equivalent circuit model, or the befitting model could be carefully and properly selected. Thirdly, in fitting the Equivalent Circuit Model (ECM) to the initial data or parameters, one must take note that the parameters are strongly dependent on temperature, heat, and losses. Such are: the Open Circuit Voltage (OCV), which is strongly dependent on the temperature, the loss processes depend on temperature; losses produced by the loss processes are dissipated as heat energy; the heat generated or consumed by the electrochemical reactions during normal operation has a defined temperature; and a system with a defined temperature window with safe, stable, and efficient operation is achievable. At the end of this research, the simulation of Lithium (Li) and Cadmium (Cd) was found to be in the proportion of 67:33, which is used to determine the strength of the reactivity of the metals. It can be informed in this article that the Bi and Li chemical compositions of the metals are equal to 49 for Li and 51 for Bismuth, which makes the overall reactivity very high, which could be used for LMB development.

Unaccounted infrastructure needs for transit-oriented developments

Increasingly, U.S. cities are focusing on transit-oriented development (TOD) policies to expand the stock of higher-density, mixed-use development near public transit stations within the context of a transit corridor and, in most cases, a regional metropolis. A TOD zone relies on a regulatory and institutional environment, public and private participation and investment, and development incentives to create vibrant, people-oriented communities and mobility options and to support business development. TODs provide local governments with more tax revenues due to increased property values (and, as applicable, income and sales tax revenues), but most planning for TODs ignores the non-transit infrastructure costs of increasing development density. This study focused on determining the water and sewer infrastructure costs for TOD zones along a rail line in southeast Florida. The finding was that millions of dollars in funds are needed to meet those water and sewer needs and that few are currently planned as a part of community capital improvement programs.

The mechanism of brand crisis influence on consumer purchase intentions in the context of green development

The promotion of new energy vehicles (NEVs) in China not only provides a pathway for the country to achieve its “dual carbon” strategic goals but also facilitates the transformation and upgrading of the automotive industry, contributing to social development and economic growth. This study examines the influence mechanism of brand crises on consumer purchase intentions within the NEV sector, an area critical to sustainable infrastructure and green development. Using a framework of “brand crisis—consumer negative emotions/perceived risk—consumer purchase intention,” and data from consumer surveys conducted in Beijing, Shanghai, Zhengzhou, and two other locations, the study employs regression models to analyze the relationship between brand crises and purchase intentions. Mediation effect models are used to explore how brand crises impact consumer purchase intentions through negative emotions and perceived risks. The results indicate that brand crises significantly reduce consumers’ willingness to purchase products from affected brands, posing a threat to the market stability and growth of the NEV sector. Moreover, negative emotions and perceived risks mediate the relationship between brand crises and purchase intentions, highlighting the importance of addressing both emotional and cognitive responses in crisis management strategies. To mitigate the adverse effects of brand crises, companies should adopt measures to improve consumer sentiment and reduce perceived risks, such as proactive communication, transparency, and effective recall procedures. Additionally, factors such as NEV performance, price, and charging infrastructure coverage also play a crucial role in consumer purchase decisions. Therefore, companies must consider these factors when formulating crisis response strategies to swiftly regain consumer trust and promote sustainable market and green development. This study contributes to the broader discourse on infrastructure development and public policy by providing insights into how brand crises in the NEV industry can be managed to support sustainable economic growth and development. By understanding the mechanisms through which brand crises affect consumer behavior, this research offers valuable recommendations for policymakers, industry professionals, and academic researchers focused on the interplay between infrastructure, development, and policy.

The role of infrastructure efficiency in economic development—The case of underused highways in Europe

In this paper, we establish a two-way causality between the phenomenon of infrastructure which is underused (the so-called “white elephant case”) and the aggregate productivity level (TFP) of the economy. On the one hand, the fact that a transport infrastructure is not used as much as it could be is itself a cause of low TFP because it represents low productivity for an important item of social capital. On the other hand, low aggregate productivity makes firms’ strategies founded on large scale of production and exports riskier, given the possibility that the political decision to build the required transport infrastructure may never be taken.

Model of competency development of professional group leaders (PGL) in higher vocational colleges in Fujian province

This study aims to take Chinese higher vocational colleges professional group leaders as the research subjects to analyze the components of their key competencies, develop the competency model of professional group leaders (PGL), and analyze the main factors influencing the model. It provides a powerful help for improving the scientific level of the construction and management of the teaching staff in higher vocational colleges and filling the gap in the research on the quality and ability of Chinese professional group leaders. A mixed research method is deployed in this study. Data are collected with the help of a self-administrated questionnaire and a semi-structured interview based on grounded theory. Data analysis involves structural equation modeling using AMOS, complemented by qualitative coding in NVivo. It concludes that the competency development model of professional group leaders comprises two main dimensions: explicit competencies and implicit competencies. Explicit competencies include cross-border adaptability (CBA), resource integration ability (RIA), innovation and development practice ability (IDPA), management leadership ability (MLA), and interdisciplinary scientific research ability (ISRA). Implicit competencies include personality attitude (PA), and intrinsic motivation (IM). The study fills a significant gap in the literature by providing a detailed model of competency for professional group leaders in the context of higher vocational education, offering a practical framework for improving the training and management of teaching staff and promoting the development of professional groups effective in vocational colleges.
