Authors: Li Yansong
Published: June 2024

Nowadays, due to various reasons, more students are beginning to pursue higher academic degrees, such as master's degrees. This article discusses the factors that influence the chances of graduate admissions. The aim is to quantify each determinant by establishing a linear model, thus helping everyone understand how much each factor can affect the admission chance. The dataset used in this article comes from the Kaggle, which includes eight variables and 400 observations. This article establishes several multiple linear models using the smallest AIC selection, the smallest BIC selection, and the LASSO selection. Models are screened based on some indicative values such as R2adj, SSres, and R2. After establishing the final model, assumptions (Normality, homoscedasticity, multicollinearity, linear relationship) and prediction errors are checked to verify the model's effectiveness. The article ultimately finds that every predictor positively correlates with the admission chances. It means that the more achievements an applicant has, the higher the chance of admission. This conclusion is consistent with our initial hypothesis. The final results can help applicants understand the importance of each application material (predictor). By inputting their existing achievements for each predictor into the model, they can predict their chances of admission, identify deficiencies, and work on improvements.

Authors: Tai Yang
Published: June 2024

The gas turbine is a kind of efficient heat engine that has occupied a wide range of fields. Compared with other traditional heat engines, gas turbines are characterized by high thermal efficiency, operational flexibility, free fuel options and low pollutants and achieve an irreplaceable position in modern industrial production. The stationary gas turbine is mainly used for power generation and fits many additional units with ample space in plants. So far, many improvements on different parts of stationary gas turbines have been applied to practical production. Excellent high-temperature resistance materials are used for the blades themselves and the coatings. The cooling technique is also well developed so that blades can endure higher temperatures for higher thermal efficiency. Despite the flame instability, annular combustors are widely installed in stationary gas turbines for better combustion process. The monitoring method and cooling rings are applied to prevent the deformation of flame tubes and timely maintenance to ensure normal working conditions. Combined heat and power (CHP) is a better gas turbine-based system to supply both heat and electricity. But it has some efficiency problems when electricity demand changes. The possible solution may lie in units preheating and peak-shaving.

Analysis of the Role of Moral Values in Building a Community of Human Destiny
Authors: Luo Yangqing
Published: June 2024

The concept of “community of human destiny” actually refers to the good world order, which is not a mechanical subversion of the current international order, but a reshaping of the current international order based on the law of human history development. A community of shared future for mankind is a concentrated expression of the common interests and responsibilities of all countries in the world. It is a new type of international relations theory built under the guidance of the thought of major-country diplomacy with Chinese characteristics in the new era. It is different from the value orientation of “national interests first”, “hegemony theory” and “zero-sum game theory” in traditional Western theories of international relations. The community of human destiny breaks through the concepts of economic community and political community, gets rid of the shackles of western pure monism values and formal justice, returns to the essence of “human subject”, highlights the relative independence of human society, and forms the value of the community of all mankind on this basis.

The Transformation of University Governance Abroad Under the Perspective of New Public Management
Authors: Liang Hanzhong
Published: June 2024

Known as New Public Management (NPM) or New Managerialism, this approach has been the predominant guiding philosophy in Western university governance since the 1980s. The core of this philosophy emphasizes customer supremacy and market competition, advocating for customer needs and orientations by incorporating market mechanisms to stimulate innovation in universities. Additionally, NPM emphasizes clear accountability, output orientation, and performance evaluation. It requires universities to set clear goals and plans in their operations, quantify their outputs, and proactively accept market supervision and evaluation. Influenced by this theory, Western university governance has undergone significant transformation. The role of the government has shifted from that of a manager to a service provider, offering more policy support and resource guarantees for students. Meanwhile, after introducing market mechanisms, university governance has shifted from government-dominated to multi-centric governance, granting universities greater autonomy and decision-making power, allowing them to independently adjust their development strategies according to market needs and social changes. These transformations have injected new vitality into the development of Western universities and provided useful references for university governance reforms in other countries.

Published: June 2024

For the purpose of our research, we aim at explaining the principles of different types of hydropower and providing an overall review on global deployment. We searched for related and authoritative articles, reports and statistics and then made comparison about these data. Overall, different types of hydro power generation are used worldwide, with run-of-river, conventional storage and pumped storage being the main types of hydro power generation. Each method has its own virtues and drawbacks. In addition, developing countries have the features of abundant resources and huge economic effects by using hydropower but lack of fund support and environmental issues. For developed countries, complete and ripe hydropower systems are set however there is less potential to develop new sites. Therefore, we suppose that governments of developing countries should attach importance to and promote large scale hydropower generation by investing more funds whilst that of developed countries should maintain the current situation and keep devoting in refining new hydropower technologies and finally implement them.

The traditional energy-intensive heterogeneous thermochemical processes have historically yielded a substantial quantity of high-value chemicals, but it simultaneously results in significant emission of carbon dioxide (CO2) and nitrogen oxide (NOx) species, and a heavy reliance on fossil resources. A promising strategy to address it is to utilize CO2 greenhouse gases and NOx pollutants as feedstocks for production of high-value chemicals under ambient conditions driven by renewable energy sources. To achieve the objectives, it is essential and highly desirable to focus on the development of electrocatalytic technology for construction of C-N bonds beyond the C-O or N-O cleavage and formation. To date, however, the ambiguous reaction mechanism and severe competitive side reactions has greatly constrained the activity and selectivity of the electrocatalytic C-N coupling reactions. This review is devoting to summarizing the recent progress of electrocatalytic C-N coupling processes in synthesizing urea, amides, amines, and related compounds with an emphasis on understanding of the fundamental design principles of electrocatalysts and insightful perspectives of modulating heterogeneous electrocatalytic processes. It is expected to be constructive for the electrosynthesis of a wide range of high-value chemicals containing C-N coupling.
A Typology of Business Model Reconfiguration in Incumbent Firms
Authors: Kenlind Sarah , Havemo Emelie
Published: June 2024

The purpose of this study is to shed light on patterns of change in incumbent firms and, in doing so, identify different types of approaches to business model reconfiguration (BMR). Drawing on data spanning a 10-year period in the empirical context of mature, low-tech firms in the Swedish wood manufacturing industry, this paper develops a typology of BMR approaches, namely Incremental, Modular, Integrated and Transformational BMR. The paper illustrates the nature of these types and offers several insights into the meaning and significance of each for our understanding of BMR and the design of business models in general.
A tool for a design-driven innovation approach to more sustainable business models
Authors: Corà Tommaso , Fazio Lucilla
Published: June 2024

Purpose
The growing imperative for sustainable business practices has led to a recognition that companies must transform their business models to encompass economic, social, and environmental value. At the heart of this transformation is the triple bottom line framework, which evaluates business success in the three dimensions of profit, people, and the planet. Simultaneously, design-driven innovation embraces future-oriented approaches that include people and the ecosystem as stakeholders, while evolving the lenses of innovation, namely desirability (planet), feasibility (network), and viability (prosperity). This evolution offers a new perspective that extends the triple bottom line in business model design by considering the feasibility of achieving impactful, original, and useful innovations.
We explore a potential method for designing a business model anchored in the conceptualization of design-driven innovation and a tool to support the creative exploration and coherence assessment of more sustainable (than those currently in use) business models.
 
Design/Methodology/Approach
We built on previous knowledge of design, design-driven innovation, and business model design, and merged with insights from our direct experience as design-driven innovation practitioners, including in applying the tools in different instances with client companies.
 
Findings
We propose the Design-Driven Innovation Business Model Canvas, and provide initial anecdotal evidence from its potential to support the creative exploration and coherence assessment of sustainable business models.
 
Originality/Value
Our tool is designed to merge the design-driven innovation perspective with business design requirements to generate more sustainable business models than those currently in use. We also propose a new conceptualization of the three lenses of innovation, which we then relate to the triple bottom line.
