An investigation was conducted into the impact of various process parameters on the surface and subsurface quality of glass-ceramic materials, as well as the mechanism of material removal and crack formation, through the use of ultrasonic-assisted grinding.

A mathematical model of crack propagation in ultrasonic-assisted grinding was established, and the mechanism of crack formation was described through the model. A series of simulations and experiments were conducted to investigate the impact of process parameters on crack depth, surface roughness, and surface topography during ultrasonic-assisted surface and axial grinding. Additionally, the mechanism of crack formation was explored.

During ultrasonic-assisted grinding, the average grinding forces are between 0.4–1.0 N, which is much smaller than that of ordinary grinding (1.0–3.5 N). In surface grinding, the maximum surface stresses between the workpiece and the tool gradually decrease with the tool speed. The surface stresses of the workpiece increase with the grinding depth, and the depth of subsurface cracks increases with the grinding depth. With the increase of the axial grinding speed, the subsurface damage depth increases. The roughness increases from 0.780um/1.433um.

A mathematical model of crack propagation in ultrasonic-assisted grinding was established, and the mechanism of crack formation was described through the model. The deformation involved in the grinding process is large, and the FEM-SPH modeling method is used to solve the problem that the results of the traditional finite element method are not convergent and the calculation efficiency is low.

As Canadian universities increasingly serve diverse student populations, there is a need to understand the experiences of racialized students, including their experiences of bias and perception of the quality of postsecondary education. We utilize qualitative interviews with 38 ‘Asian-Canadian’ undergraduate students at a Canadian university as a case study to explore challenges to identity expression, strategies to earn admission, and campus resources. The findings reveal that students’ perceive stereotyping. They point to their families as preparing them for university admission as well as describing extracurricular endeavours and international baccalaureate education as helping them meet admission requirements. Study participants described challenges in university, including accessing some services. The findings are limited in the sense of not being able to distinguish whether the concerns related to access to resources was unique to these students or the broader student population. More research is needed on the experience of racialized students in Canadian postsecondary institutions.

Prior studies have confirmed market segmentation as an important shackle to China's macroeconomy upgrade, but the systematic analysis of microenterprise upgrade remains inadequate. This paper aims to investigate the nonlinear impact of market segmentation on microenterprise upgrade.

The price method was applied to calculate China's provincial market segmentation, including commodity, capital, labor and energy. The generalized method of moments was employed to examine the nonlinear impact of market segmentation on the upgrading of manufacturing enterprises based on microenterprise data from 2003 to 2019.

First, China’s heterogeneous market segmentations have been significantly reduced. Macroeconomics and policies are critical factors in market integration. Second, there is an inverted U-shaped relationship between China’s total market segmentation and the upgrading of manufacturing enterprises. Third, the relationship between the commodity market segmentation, labor market segmentation, energy market segmentation and manufacturing enterprises' upgrade is shown as an inverted U-shaped. Nevertheless, the relationship between the capital market segmentation and upgrading of manufacturing enterprises exhibits a U-shape.

The impact of market segmentation on the upgrading of manufacturing enterprises in China performs nonlinearly. An inverted U-shaped relationship exists between market segmentation in commodity, labor and energy and the upgrading of manufacturing enterprises, while a U-shaped relationship prevails between capital market segmentation and the upgrading of manufacturing enterprises.

The purpose of this paper is to review and discuss existing literature and available research findings related to understanding elder abuse and neglect in culturally diverse communities, particularly the Chinese immigrant community in Canada. The conceptual understandings of elder abuse are examined, based upon the socio-cultural context and challenges faced by aging Chinese immigrants.

Previous literature and research publications related to elder abuse and neglect related to Chinese in Canada were reviewed and synthesized. Statistical information and research findings were summarized to illustrate the socio-cultural context that defines elder abuse and neglect experienced by aging Chinese immigrants in Canada.

From a culturally diverse perspective, influence of race, ethnicity, immigrant status, and cultural norms on the recognition, identification, prevention and intervention of elder abuse and neglect are important to consider. A key message for professionals working with the aging population, particularly older immigrants from ethno-cultural minority background, is that understanding the social cultural context in which elder abuse or neglect emerges is critical. For many of the aging Chinese immigrants in Canada, the socio-cultural circumstances that they have experienced, their social environment, and various barriers and challenges further prevent them from being aware of this emerging concern. Cultural norms and practices have played a critical role in their access to preventive and intervention services.

Although this paper is not based upon a particularly empirical research study, the research and literature synthesized are both empirically and conceptually based. As indicated in the review of previous research publications on the subjective matter of elder abuse and neglect in aging Chinese immigrants in Canada is limited. Research on various issues related to elder abuse and neglect in ethno-cultural minority communities is also relatively scant. Evaluation research on prevention and intervention programs is desperately needed so as to facilitate the further establishment of best practice prevention and intervention models that are culturally appropriate and effective. While research engagement with minority groups such as the aging Chinese immigrants who do not speak English or are not familiar with the research culture in the western civilization could be challenging, academic researchers and service providers in both the mainstream and ethno-cultural minority communities should further align themselves in practice-research partnership endeavors to ensure the safety and wellbeing of the aging vulnerable individuals could be better maintained.

In order to provide culturally competent services, service providers should be aware of cultural differences in attitudes towards elder mistreatment, including the ways in which specific types of abuse (e.g. financial abuse) are defined within ethno-cultural communities, and the cultural values and experiences that shape these understandings and determine attitudes or barriers towards reporting, intervention, and service use.

This paper is a first attempt in the research community to synthesize a few critical issues related to elder abuse and neglect in the aging Chinese immigrant community in Canada. The paper has connected previous empirical findings related to Chinese older adults as well as other culturally diverse aging populations to the conceptualization of elder abuse and neglect by considering the unique socio-cultural context faced by the ethnocultural older adults.
