Analysis of China’s Ping an Firm‘S Strategy Management : A Case Study

Insurance is an important pillar of the financial system. With the steady growth of China's economy, China's property insurance industry has maintained a stable growth trend in recent years, playing an important role in ensuring the development of national economy and improving the social security system. Since 2018, China's property insurance has entered a transition period, with negative premium growth. This study is supported by social learning theory. The internal and external environment has brought serious challenges to the development of the industry, but also brought new development opportunities. As a leading enterprise in the property insurance market, Ping-an Property Insurance has encountered serious tests in terms of market share, team growth, internal management, etc., especially in the face of a series of new situations, such as competition among enterprises, the threat of new enterprises, the threat of alternative products, the threat of buyers' bargaining power on products, etc. Therefore, it is necessary for Ping An to formulate a development strategy in line with the new situation, so as to promote the development of property insurance, enable the company to achieve long-term stable growth in the new business environment, and complete the transformation from a traditional company to a skilled company. At the same time, the transformation of Ping-an Property Insurance will also provide some learning for the development of other property insurance companies in the new period, and jointly contribute to the development of China's property insurance industry and national economic construction. This article uses qualitative analysis methods for analysis and SWOT method for content analysis.

The Review of CEO Gender: Based on the Perspective of Empirical Literature

In China, the CEO position is still dominated by men in traditional companies. However, in some emerging industries and the Internet field, there are gradually increasing numbers of female CEOs and the rise of female leadership. In the international community, male CEOs still dominate, and female CEOs are showing a gradually changing trend. CEO gender promotes economic diversity in economic construction, which helps companies better respond to market competition and changes and promotes the economic construction of enterprises. For technology, CEO gender drives innovation and problem-solving, and gender diversity encourages different ways of thinking and problem-solving, which is crucial for innovation and technological progress. At the social level, the promotion of gender diversity can help reduce gender discrimination and promote a more equal and inclusive society. All in all, the theoretical significance of CEO gender in economic construction, technological progress, and social development is to promote diversity and inclusion and create a more competitive, innovative, and just social and business environment. In practice, companies and governments should proactively take steps to ensure that more women have the opportunity to serve as CEOs and other senior leadership positions to fully leverage the advantages of gender diversity.

Examining the economic impacts of caregiving among families of children of medical complexity: A qualitative study to inform inclusive economic models.

Children with medical complexity (CMC) represent a heterogeneous group of children with multiple, chronic healthcare conditions. Caregivers of CMC experience a high intensity of caregiving that is often variable, extends across several networks of care, and often lasts for the entirety of the child's life. The economic impacts of caregiving are yet understudied in the CMC context. There have been recognized limitations to the sole use of quantitative methods when developing economic models of disease because they lack direct caregiver voice and context of caregiving activities and existing methods have been noted to be ableist. The purpose of this study was to explore the economic spillover impacts of caregiving among families of CMC using their own words and perspectives with the intent of expanding caregiver-centered perspectives when developing economic models. This study was a secondary analysis of a qualitative study that was conducted to examine family management practices among caregivers of CMC and their social networks. Caregivers of CMC were recruited through a Pediatric Complex Care clinic at an academic medical center in the mid-Atlantic region, USA. This study used inductive qualitative descriptive methods and the use of a template to define features of the person impacted and to define the economic construct as either a direct or indirect/spillover cost. Twenty caregivers were included in this study. Perspectives from the caregivers of CMC revealed several key themes: (1) time investment in caregiving - impacting the primary caregivers; (2) physical and mental health impacts - impacting the child themselves, siblings, and the primary caregivers; (3) impacts to leisure activities and self-care - impacting the child themselves, siblings, and the primary caregivers; (4) impacts to the social network/social capital. The themes described can be operationalized into inclusive family-centered models that represent the impacts of caregiving in the context of the family units of CMC. The use of qualitative methods to expand our development of quantitative economic models can be adapted to other populations where caregivers are involved in care. Caregivers can and should have an active voice in preference-based assessments that are operationalized in economic contexts to make them more inclusive. n/a. RR2-10.2196/14810.

Preparation of Newly Polymer-Coated Microbial Pellets and Their Adsorption and Degradation Properties for Oil-Containing Wastewater.

Water is the lifeblood of everything on earth, nourishing and nurturing all forms of life, while also contributing to the development of civilization. However, with the rapid development of economic construction, especially the accelerated process of modern industrialization, the pollution of oily sewage is becoming increasingly serious, affecting the ecological balance and human health. The efficient elimination of pollutants in sewage is, therefore, particularly urgent. In this paper, a core-shell microbial reactor (MPFA@CNF-SA-AM) was fabricated by using nanocellulose and sodium alginate (SA) particles embedded with microorganisms as the core and lipophilic and hydrophobic fly ash as the outer shell layer. Compared with that of free microorganisms and cellulose and SA aerogel pellets loading with microorganisms (CNF-SA-AM), which has a degradation efficiency of 60.69 and 82.89%, respectively, the MPFA@CNF-SA-AM possesses a highest degradation efficiency of 90.60% within 240 h. So that this self-floating microbial reactor has selective adsorption properties to achieve oil-water separation in oily wastewater and high effective degradation of organic pollutants with low cost. The adsorption curves of MPFA@CNF-SA-AM for diesel and n-hexadecane were studied. The results showed that the adsorption follows the Freundlich model and is a multimolecular layer of physical adsorption. In addition, the degradation mechanism of diesel oil was studied by gas chromatography-mass spectrometry. The results showed that diesel oil was selectively adsorbed to the interior of MPFA@CNF-SA-AM, and it was degraded by enzymes in microorganisms into n-hexadecanol, n-hexadecaldehyde, and n-hexadecanoic acid in turn, and finally converted to water and carbon dioxide. Compared with existing oily wastewater treatment methods, this green and pollution-free dual-functional core-shell microbial reactor has the characteristics of easy preparation, high efficiency, flexibility, and large-scale degradation. It provides a new, effective green choice for oily wastewater purification and on-site oil spill accidents.

Exploring the feasibility of utilizing high plastic clays as an alternative material to bentonite clay in the production of ceramic tile: Advancing towards efficient life cycle cost

The environmental challenges and high cost of raw materials (i.e., bentonite clays) for the production of ceramic tiles raise concerns for the ceramic industry to look for alternative materials. Therefore, the current research aimed at exploring the possibility of using high plastic clays as a replacement for Bentonite clay in the manufacturing of ceramic tiles. Two different types of high plastic clay in different proportions (i.e. 0–5 %) were used in the preparation of ceramic tiles. A comprehensive material characterization, shrinkage, visual index, flexural strength, water absorption, and microstructural investigation was carried out. The results revealed that the incorporation of plastic clays RC1 from 1 % to 5 % showed a decrease in the flexural strength of ceramic tiles as compared to that of ceramic tiles with bentonite clay. The water absorption of ceramic tiles using RC1 increased with the incorporation of high plastic clays for high plastic clays. However, specimens with all replacements of bentonite clay with high plastic clays showed flexural strength greater than the minimum specified limit of ISO 10545-4. Moreover, it was observed that the replacement of bentonite clay with high plastic clays exhibited higher shrinkage. Further, the visual index of all the specimens did not show any sign of the presence of black core in the ceramic tiles incorporating high plastic clays. The life cycle assessment (LCA) was carried out for the possible utilization of high plastic clays in place of bentonite clay to produce ceramic tiles. The results showed that less than 5 % high plastic clay can effectively be used for manufacturing ceramic tiles leading to economical and sustainable construction products. Hence, it can be concluded that the high plastic clays can be utilized as an alternative to bentonite clay material for manufacturing sustainable ceramic tile leading to sustainable finishes in construction.

Simulation and multi-scenario prediction of land-use change in the Gansu section of the Yellow River Basin, China

Introduction: The Gansu section of the Yellow River Basin is an important water resource conservation and replenishment area for the entire Yellow River Basin. With urbanization and socio-economic development, it is urgent to study the characteristics of land-use change and its future simulation in order to realize the coordinated ecological and economic development.Methods: Based on the patch-generating land-use simulation (PLUS) model, this paper investigated the main drivers of land-use type expansion with a comprehensive consideration of natural and socio-economic aspects; moreover, the study simulated land-use change in 2030 under the four scenarios of natural development, cultivated land protection, ecological priority, and economic construction.Results: The results showed the following: 1) the prediction of land-use types continued the historical evolution since 1980. Grassland, cultivated land, and forest land were still the dominant land types, accounting for more than 87% of the basin’s total area. Water bodies and wetlands remained relatively stable, and there was an obvious increase of approximately 20% in construction land. 2) Construction land and grassland were primarily driven by the social factor of the distance from the primary road and the distance from the secondary road, respectively. The cultivated land was greatly affected by the economic factor of population density. 3) The cultivated land protection scenario was the only one of the four scenarios that could make the cultivated land area increase positively, with an increase rate of 0.5%. This scenario also restricted effectively the conversion of cultivated land into construction land. The ecological priority scenario can expand grassland obviously with a proportion of 1.82% and slow down oasis desertion. The economic construction scenario can increase the construction land area the most by a rate of 25.5% to accelerate the economic development of specific regions in the study area.Discussion: Therefore, implementing policies on the basis of choosing suitable scenarios in different areas was significant for optimizing the land-use structure, promoting the efficient use of land resources and ecological environment in the Gansu section of the Yellow River Basin.

An Analysis of Holistic Education Models in Mainland China’s Higher Education Institutions: A Case Study of College English Curriculum

Over the last four decades, the field of education in mainland China has seen sustained and stable growth. However, the very essence of education has undergone significant changes. In the era spanning from the 1980s to the mid-1990s, the primary aim of education was to serve economic construction and modern development, with a clear emphasis on utilitarian and instrumental characteristics. By the late 1990s, there was a shift towards advocating for quality education that prioritizes the comprehensive development of individuals, gradually embracing the concept of holistic education across the Chinese mainland. College English courses, mandatory for all non-English major undergraduates at Chinese universities, stand as a pivotal component of general education. Amidst the extensive backdrop of educational reform and development in mainland China, college English curriculum have experienced profound changes. The “College English Curriculum Guidelines (2020)” recently released by the Ministry of Education highlights that college English courses possess both instrumental and humanistic dimensions. The instrumental aspect is demonstrated through enhancing students’ comprehensive abilities in listening, speaking, reading, writing, and translating English, while its humanistic core is rooted in a people-oriented approach that celebrates human values and emphasizes the cultivation of comprehensive qualities and overall development. This paper aims to explore the practical model of implementing holistic education within college English curriculum, adhering to the specific requirements of the 2020 guidelines, across four dimensions: curriculum system, instructional approaches, educational resources, and faculty strength.

Effect of Bolts Overloading in Flange-Type Joints

Abstract The joints of bars composed of flanges and high-strength bolts are currently used in steel structures as simple and economical construction solutions. This paper presents some theoretical aspects regarding the behavior and calculation of joints with flanges and partially pre-tensioned bolts. The overloading of the pretensioned high-strength bolts produced by the tensile effort resulting from the external actions is usually neglected in the technical materials and in the design norms for constructions, as long this tensioning effort does not exceed the pretensioning force of the high-strength bolts. The overloading effort of the bolts can be evaluated theoretically by estimating the relative stiffness of the flanges and bolts and confirmed through experimental tests and computer simulations. This paper also theoretically and computationally analyzes a joint for a tensioned bar made up of pre-stressed high-strength bolts and end flanges.

Local Institutional Collaboration Models for Coastal Communities in North Sumatra

The social network of those managing mangrove forests sustainably in the districts of Langkat and Batu Bara is the subject of this study. The state of affairs indicates that the government has not been able to collaborate with stakeholders on mangrove forest management projects involving the local community that are systematic, synergistic, and sustainable. Finding a network of stakeholders is crucial to designing a mangrove forest management program holistically and sustainably. Stakeholders in the Nibung Hangus Sub-district, Batu Bara Regency, namely Lubuk Kertang Village, Pasar Rawa Village, Tapak Kuda Village, and Bagan Baru Village, maintain mangrove forests symmetrically through cooperative efforts. Rehabilitating degraded mangrove forests is heavily impacted by the structure of current networks, which includes social and economic construction and tenure components or rights to forest property. This research aims to determine the structure of networks and the function of stakeholders—actors and institutions—in managing mangrove forests. Descriptive analytic approaches were employed in the qualitative conduct of this study.

Research on the Historical Experience of the Northwest Ancient Silk Road under the Background of "The Belt and Road" Construction

"Belt and Road" represents a corridor of collaboration and mutual gain, aimed at facilitating balanced growth and widespread prosperity. It is a peaceful road to enhance understanding and trust and strengthen all-round exchanges. After Zhang Qian's departure, the ancient Silk Road in the Northwest after the Western Regions was unblocked, political and economic ties between China and foreign countries under normal conditions were established, and the Silk Road trade was further developed. Today, the "Belt and Road" is not a replica of the "Silk Road" but a continuation of the "Silk Road", The "Belt and Road" initiative not only brings huge economic extension to China's economic construction, but also promotes the economic prosperity of countries in the world, strengthens political exchanges among countries in the world, and makes great contributions to the construction of world civilization. In this context, we need to deepen our understanding and understanding of the ancient Silk Road from history, and study the historical value brought by this ancient important channel from more angles. The important role is to learn from historical experience so that it can be used forever.

Theories and practices of disability from the Global South: a critical anthropological perspective.

"Critical disability studies" (CDS) is an interdisciplinary field of research that examines social, political, economic, racial, gendered and historical constructions of bodily non-normativity across different geopolitical areas and scales. Despite its diverse and multiple contributions and objectives, current research in critical disability studies has been described as mainly focusing on disability issues in the Global North and as having universalizing tendencies. In this context, intersubjective perspectives and empirical data offered by ethnographic works in medical and disability anthropology and related disciplines have been either in accord or tension with the broader field of CDS. On the one hand, this review article illustrates the many ways anthropologists have adopted various research perspectives to explore bodily non-normativity outside settings in the Global North. On the other, it shows the importance of research by anthropologists working on topics related to disability, as well as their recent fruitful collaborations with CDS scholars and approaches. By exploring these epistemological and empirical entanglements, this paper concludes that deeper engagements between CDS and anthropology, as well as a more thorough focus on the ethnographic analysis of bodily non-normativity, can open new creative routes for the analysis of disability in various world contexts.

The study examines the relationship among organizational culture, employee performance, employee satisfaction and turnover in the telecommunication sector of Pakistan. Empirical studies are needed to understand the phenomena, so that the organizations would be able to handle the barriers in management objectives. It was a field study so survey was formed and conducted; data was gathered through distributed questionnaires from 260 employees of public & private, national and multinationals organizations from the cities of Rawalpindi-Islamabad. All the employees willingly participated in the survey though their confidentiality was in tacked. Interestingly the results of this specific investigation make this study unique and important as it indicated that organizational culture types Community, Innovative, Competitive and Bureaucratic on employee performance, satisfaction and turnover have different impacts. The study relies on cross-sectional data obtained once from employees of multiple multinationals and national organizations. The employees were from all three types of organizations i.e. service providers, contractors and sub-contractors. Regression tests were applied to analyze the data. . It leads to conclusion that employees are performing well, even being unsatisfied and want to remain with their current jobs. This study provides the knowledge that the results of the measures of same constructs cannot be same across different cultures and countries. With this study government and managers should realize the alarming situation in their organizations regarding employees’ behaviors in sometimes unfeasible organizational cultures. The future studies should examine the political and economic constructs and their influence on organizational culture and employees. The present study wishes to contribute in the knowledge gap regarding how organizational culture is impacting employees’ performance, satisfaction and turnover in telecommunication sector of Pakistan It also raises the importance for exploring and developing the theories on the basis of economic and political aspects rather perceiving single theory equally across different cultures.

Interpretation of specification for service of cancer screening for workers

As the backbone force of China's social and economic construction, the health status of workers is closely related to the nation's productivity and social development. Currently, cancers have become one of the major diseases threatening the health of workers. However, there are still many shortcomings in the cancer screening services for the workers. To standardize cancer screening services for workers, ensure the quality of screening services, and improve the overall screening effectiveness, 19 institutions, including Peking Union Medical College Hospital of the Chinese Academy of Medical Sciences, have jointly formulated the Group Standard "Specification for service of cancer screening for workers (T/CHAA 023-2023)". This standard follows the principles of "legality, scientific rigor, advancement, and feasibility" and combines the frontier scientific advances in cancer screening. It clarifies the relevant requirements for service principles, service design, service delivery, service management, service evaluation, and improving worker cancer screening. Implementing this group standard will help connect the common screening needs of workers, employers, and cancer screening service providers, standardize the screening process, improve screening quality, and ultimately increase the early diagnosis rate and survival rate of cancer patients. Consequently, this group standard will help safeguard workers' health rights and interests, ensure the labor force resources, promote the comprehensive coordinated and sustainable development of society, and contribute to realizing the "Healthy China 2030" strategic policy.

The Digital Economy and Carbon Intensity: Empirical Evidence from Chinese Cities

This study examines how the development of the digital economy affects urban carbon intensity. Using a sample of 281 prefecture-level cities in China from 2011 to 2021, we employ principal component analysis and entropy weighting analysis to assess the comprehensive level of digital economic development. Various models, such as benchmark regression, variable substitution, interactive fixed effects, robust standard errors with double clustering, and instrumental variables, are employed to empirically analyze the impact and mechanisms of digital economic development on carbon intensity in multiple Chinese cities. The results indicate that the development of the digital economy can reduce urban carbon intensity. Based on these findings, this paper puts forward policy recommendations to promote digital economic development and reduce carbon intensity, including increasing efforts in digital economic development and related infrastructure construction, narrowing the regional disparities in digital economic development, improving regulations and systems related to low-carbon development in the digital economy, and adapting to international economic and political development trends, in order to contribute to the achievement of the "dual carbon" goals.

Molecularly imprinted ratiometric fluorescence sensor for visual detection of 17β-estradiol in milk: A generalized strategy toward imprinted ratiometric fluorescence construction.

17β-Estradiol (E2) is the typical endocrine disruptor of steroidal estrogens and is widely used in animal husbandry and dairy processing. In the environment, even lower concentrations of E2 can cause endocrine dysfunction in organisms. Herein, we have developed a novel molecularly imprinted ratiometric fluorescent sensor based on SiO2-coated CdTe quantum dots (CdTe@SiO2) and 7-hydroxycoumarin with a post-imprint mixing strategy. The sensor selectively detected E2 in aqueous environments due to its two fluorescent signals with a self-correction function. The sensor has been successfully used for spiking a wide range of real water and milk samples. The results showed that the sensor exhibited good linearity over the concentration range 0.011-50 μg/L, obtaining satisfactory recoveries of 92.4-110.6% with precisions (RSD) < 2.5%. Moreover, this sensor obtained an ultra-low detection limit of 3.3ng/L and a higher imprinting factor of 13.66. By using estriol (E3), as a supporting model, it was confirmed that a simple and economical ratiometric fluorescent construction strategy was provided for other hydrophobic substances.

Assessment of ecological civilization construction from the perspective of environment and health in China

This study innovatively evaluated ecological civilization in China from the perspective of environment and health. A Composite Environmental Health Index (CEHI) was constructed based on the Driving force-Pressure-State-Impact-Response (DPSIR) and Coupling Coordination Degree (CCD) models. Results showed that significant and sustained improvements were observed in the ecological environment after ecological civilization, while economic development continued to progress at a steady pace. However, the advancement in population health (impact subsystem), exhibited comparatively modest progress, potentially linked to issues such as demographic aging and the enduring consequences of past exposure to environmental pollutants. At the provincial level, the regional development was uneven. The CEHI performance was highest in the eastern regions, followed by the central regions, with the western regions showing the least progress. Beijing, Guangdong, Jiangsu, Shanghai, and Zhejiang emerged as top performers with higher CEHI scores, which can be attributed to their favorable geographical positioning and the response subsystem. Conversely, northeastern regions (Heilongjiang, Jilin, and Liaoning) and northwestern regions (Shaanxi, Gansu, Ningxia, and Qinghai) experienced limited advancements in post-ecological civilization implementation. For these underperforming regions, there is a pressing need to intensify efforts aimed at enhancing their response subsystems. In summary, China's pursuit of ecological civilization has yielded significant successes, potentially offering valuable insights for other nations striving for sustainable development. The ecological civilization model's integration of ecological environmental protection into economic, political, cultural, and social constructs may serve as a meaningful reference for the sustainable development of other countries.

Construction and evaluation of a large radiation detector for Positron Emission Tomography applications

Large arrays of pixelated scintillator potentially have application in economical construction of PET scanners. In this investigation, we constructed and evaluated a detector with an active area of 32.26 × 13.47 cm2. It is based on a 218 × 91 array of 1.4 × 1.4 × 15 mm3 LYSO elements (pitch 1.48 mm). Scintillation light is detected with a 5 × 12 array of silicon photomultipliers (SiPM) arrays. Each array consists of an 8 × 8 array of 3 × 3 mm2 (pitch 3.35 mm) SiPMs. Performance of these devices are enhanced and stabilized by cooling them. Testing revealed that the detector was able to detect 90% of the theoretically detectable 511 keV photons. The resolvability index (a measure of the ability to identify individual detector elements from background) is 0.24 ± 0.04. Additionally, the average energy resolution for the complete detector is 18.3%. These results compare well with those reported for much smaller detector modules.
