This paper aims to explore the interplay between industrial diversity and sustainable economic development in US counties.

Among other popularly used measures, this study uses an underused measure, Hachman index, to gauge the degree of industrial diversity in the models. To capture the impact of industrial diversity on the local community, this study estimates the relationship of two diversity measures to four traditional socioeconomic indicators: per capita personal income growth, gross domestic product per worker, income inequality ratio and poverty rate.

Statistical results suggest that industrial diversity, which is measured by Hachman index, is significantly related to the four socio-economic indicators. Industrial diversity can positively contribute to regional per capita personal income growth and mitigate income inequality and poverty stress; however, it is negatively related to the gross domestic product (GDP) per worker, which means industrial specialization may contribute to GDP per worker growth.

The findings of this study show that there is a nonlinear relationship between industrial diversity and all socioeconomic indicators. Most of the control variables, human capital variables and business and industry profile variables also display significant and positive impacts on economic development.

Scenic tourist buildings are the important material security conditions for famous scenic cities to carry out tourism activities, and the level of their planning and design will directly affect the tourists' recognition of the scenic spots. Based on this, a research on the evaluation of the coupling degree between scenic tourist buildings and sites based on analytic hierarchy process was put forward. First of all, the theory of the coupling between the landscape tourism architecture and the site was elaborated, and then the landscape tourism architecture and its planning and design were proposed; taking a certain project as an example, planning and design of its teahouse, villas, sightseeing stand and other buildings were analyzed emphatically; in addition, the evaluation of the coupling degree of AHP was used to show that the planed and designed scenic tourist buildings are in the landscape and they can also be the landscape.

Diversity and uncertainty summarise Taiwan’s Generation Z. Diversity because the background of fewer than 3.4 million Taiwanese, which is less than 20% of the overall population, cannot be included in a ‘one-fits-all’ category. As a sovereign nation, Taiwan has developed through various cultural, economic, and political stages. Democratic freedom has given the Taiwanese the right and terrain to de-Sinicise their homeland and politically construct ‘Taiwanese Consciousness’. These points are essential, because this is the societal fabric given to Generation Zers. Apart from national identity, this chapter illustrates the uncertainties that Generation Zers are facing in relation to education, job opportunities, and living standards. It is suggested that conditions are easier for those that have received ‘superior’ education and have enjoyed family-economic support. Their consumer behaviour, Generation Z in the workplace, as well as voters are also carefully analysed in this chapter.

This article looks at the differences and similarities between globalization and the role of China on globalization, in particular for the Hong Kong Special Administrative Region of China (HKSAR).

This article is based on research, reading, and interviews on globalization.

China is promoting the new globalization of the century called Belt and Road Initiative (BRI) which is a unique way to boost again the economy of China.

Studies of the New Maritime and Land Silk Road of China are rare; in particular, the role of the HKSAR is ignored. Macau also plays a role because it was the first point of globalization in the seventeenth century. China is really a global country, and the Chinese are numerous in all continents. Chinese Internet role is also mentioned.

Globalization is a key concept not only for China and Asia but also for the Hong Kong Special Administrative Region (HKSAR), Africa, and countries in Latin America such as Bolivia and Venezuela. This article looks at the differences and similarities between globalization and the role of China on globalization. The HKSAR and the Greater Bay Area are part of the same country. China is developing the new globalization of the century called, in 2017, the Belt and Road Initiative (BRI). The current definition of Chinese globalization includes land and maritime Silk Road, now the BRI.

The purpose of this paper is to trace the changing pattern of identity politics in Hong Kong Special Administrative Region (HKSAR). It shows that in response to the massive urban renewal projects in the 2000s, “civic localism” in the form of cultural preservation movement emerged to protect local community culture against the government-business hegemony. However, due to the deepening of social integration between Hong Kong and the mainland, a new “anti-mainland localism” emerged in the 2010s against the influx of mainlanders. In 2015–2016, as a result of Beijing’s active interference in Hong Kong affairs, localism is further transformed to Hong Kong “independence.”

This paper uses a historical methodology to trace the changing pattern of identity politics in Hong Kong after it becomes a special administrative region of China in 1997.

It shows how the interaction among the following three factors has shaped the pattern of localism in Hong Kong: macro historical-structural context, social movement dynamics and the response of Hong Kong and mainland government.

This paper argues that Beijing’s hardline policy toward Hong Kong localism may work in the short run to all push the pro-independence activities underground. However, unless the structural contradiction of the HKSAR is resolved, it seems likely that anti-mainland localism and Hong Kong independence sentiment and movement will come back with a vengeance at a later stage.

The literature tends to discuss Hong Kong localism in very general terms and fails to reveal its changing nature. This paper contributes by distinguishing three different forms of localism: civic localism in the mid-2000s, anti-mainland in the late 2000s and early 2010s, and independence after 2016. It shows how the macro historical-structural transformation, social movement dynamics and the responses of the Hong Kong SAR government and Beijing government have led to the changes of civic localism to anti-mainland localism, and finally to independence.

The purpose of this paper is to derive a new lubrication model of double involute gears drive and study the effect of the tooth waist order parameters of double involute gears on lubrication performance.

The new lubrication model of double involute gears drive was established according to the meshing characteristics of double involute gears drive and the finite length line contact elastohydrodynamic lubrication theory. Numerical calculation of the lubrication model of gear drive was conducted using the multigrid method.

The results show that the oil film necking phenomenon and the oil film pressure peak emerged at the tooth waist order area and the tooth profile ends, and when compared with involute gear, the lubrication performance at the tooth waist order area is better than that at the tooth profile ends. The effect of tooth waist order parameters on lubrication performance at the tooth waist order area was greater than that at other areas.

This research will promote the application of the double involute gear as soon as possible, and it has the reference value for other types of gears.

This study aims to solve the problem of high output voltage fluctuation and low efficiency caused by the misalignment of the magnetic coupling structure in the wireless charging system for electric vehicles. To address these issues, this paper proposes a dual LCC-S wireless power transfer (WPT) system based on the double-D double-layer quadrature (DDDQ) coil, which can realize the anti-misalignment constant voltage output of the system.

First, this paper establishes the equivalent circuit of a WPT system based on dual LCC-S compensation topology and analyzes its constant-voltage output characteristics and the relationship between system transmission efficiency and coupling coefficient. 1. Quadruple D (Ahmad et al., 2019) and double-D quadrature pad (DDQP) (Chen et al., 2019) coils have good anti-misalignment in the transverse and longitudinal directions, but the magnetic induction intensity in the center of the coils is weak, making it difficult for the receiving coil to effectively couple to the magnetic field energy. 2. Based on the double-D quadrature (DDQ) structure coil that can eliminate the mutual inductance between coupling coils and cross-coupling, Gong et al. (2022a) proposed a parameter optimized LCC-LC series-parallel hybrid topology circuit, which ensures that the output current fluctuation is controlled within 5% only when the system is misaligned within the 50% range along the X direction, achieving constant current output with anti-misalignment. The magnetic coupling structure’s finite element simulation model is established to analyze the change in magnetic induction intensity and the system’s anti-misalignment characteristics when the coil offsets along the x and y axes. Finally, an experimental prototype is developed to verify the constant voltage output performance and anti-misalignment performance of the system, and the proposed anti-misalignment system is compared with the systems in existing literature, highlighting the advantages of this design.

The experimental results show that the system can achieve a constant voltage output of 48V under a time-varying load, and the output voltage fluctuates within ±5% of the set value within the range of ±60 mm lateral misalignment and ±72 mm longitudinal misalignment.

Based on the dual LCC-S WPT system, the mutual inductance between the same side coils is reduced by adding decoupling coils, and the anti-misalignment characteristics and output power of the system are improved in a certain range. It is aimed at improving the stability of the system output and transmission efficiency.

The study aims to devise a comprehensive evaluation model (CEM) for evaluating spatial equity in the layout of elderly service facilities (ESFs) to address the inequity in the layout of ESFs within city center communities characterized by limited land resources and a dense elderly population.

The CEM incorporates a suite of analytical tools, including accessibility assessment, Lorenz curve and Gini coefficient evaluations and spatial autocorrelation analysis. Utilizing this model, the study scrutinized the distributional equity of three distinct categories of ESFs in the city center of Xi’an and proposed targeted optimization strategies.

The findings reveal that (1) there are disparities in ESFs’ accessibility among different categories and communities, manifesting a distinct center (high) and periphery (low) distribution pattern; (2) there exists inequality in ESFs distribution, with nearly 50% of older adults accessing only 18% of elderly services, and these inequalities are more pronounced in urban areas with lower accessibility, and (3) approximately 14.7% of communities experience a supply-demand disequilibrium, with demand surpassing supply as a predominant issue in the ongoing development of ESFs.

The CEM formulated in this study offers policymakers, urban planners and service providers a scientific foundation and guidance for decision-making or policy amendment by promptly assessing and pinpointing areas of spatial inequity in ESFs and identifying deficiencies in their development.
