Core Viewpoint - The recent changes in undergraduate admissions at Chinese universities indicate a trend towards the cancellation of "big category" admissions, with specific majors being directly recruited instead, reflecting a shift in educational policy and student preferences [1][11][23]. Summary by Relevant Sections Changes in Admissions - China University of Petroleum (Beijing) has announced the cancellation of "big category" admissions for certain majors, specifically eliminating "Chemical and Pharmaceutical Category" and "Environmental Science and Engineering Category," and introducing direct admissions for specific majors like "Chemical Engineering and Technology" and "Environmental Engineering" [1]. - Other universities, such as Shandong University of Technology and Hubei Minzu University, have also moved to cancel big category admissions, opting for direct major recruitment [5][7]. Background and Rationale - The concept of big category admissions allows students to choose a broad category during college entrance exams, with specialization occurring in the first or second year based on performance and interest [4]. - The Ministry of Education has emphasized the need to regulate big category admissions, citing issues with mismatched training programs and student concerns about being assigned to undesired majors during the specialization process [11][12]. Issues with Big Category Admissions - The big category model has faced criticism for grouping vastly different majors together, leading to student anxiety about being placed in a major they did not intend to pursue [13][14]. - The practice of bundling popular and less popular majors has resulted in a situation where high-performing students may end up in less desirable fields, exacerbating the divide between hot and cold majors [14][15]. Adjustments and Alternatives - In response to the cancellation of big category admissions, some universities are implementing measures to provide students with more flexibility, such as allowing multiple opportunities to change majors [18][19]. - Institutions like Jiangxi University of Finance and Economics have introduced policies to facilitate major changes, while Xi'an Jiaotong University has refined its approach by creating smaller categories within colleges to offer clearer choices [18][19]. Future Directions - Despite the tightening of regulations around big category admissions, some universities continue to explore this model, indicating a mixed approach to admissions strategies across institutions [19][20]. - The ongoing debate highlights the need for universities to balance general education with specialized training, ensuring that students have adequate options and support in their academic journeys [22][23].

Core Viewpoint - The collaboration between Beijing University of Chemical Technology, Tsinghua University, and Quzhou Resource Chemical Innovation Research Institute has achieved a significant technological advancement in hydrogen production and chemical synthesis, demonstrating international leadership in the field [2][3]. Group 1: Technological Achievements - The newly developed 10 kW electrolysis technology for hydrogen production coupled with green oxidation to produce 2,5-furandicarboxylic acid (FDCA) has been evaluated and recognized as reaching an internationally leading level [2]. - The innovative concept of coupling water electrolysis with oxidation has been validated, revealing the mechanism of active oxygen generation through controlled activation of water at the anode interface [2]. - The project team has successfully designed and built a 20 kW electrolysis device, achieving a maximum current density of 1.0 A/cm², with FDCA production capacity of 56 tons/year and hydrogen production capacity of 27,240 standard cubic meters/year [3]. Group 2: Performance Metrics - The device demonstrated a 94.2% single-pass conversion rate of 5-hydroxymethylfurfural (HMF) at 7 kW operating power, with a Faradaic efficiency of 89.5% for FDCA and a selectivity of 95.0% [3]. - The space-time yield was recorded at 3.48 kg/m² per hour, with a production rate of 2.22 kg/hour for FDCA and a hydrogen production rate of 1.07 standard cubic meters/hour [3]. Group 3: Intellectual Property and Research Output - The project has resulted in the authorization of 4 national invention patents, 5 utility model patents, 2 PCT patent applications, and 1 registered trademark, along with the publication of 29 SCI papers [3].

Core Viewpoint - The article emphasizes the importance of rational criticism towards specific individuals in the medical field while defending Professor Wang Chen's reform efforts at Peking Union Medical College (PUMC) against unwarranted negative perceptions [1][2][3]. Group 1: Criticism and Defense - Recent criticisms directed at certain doctors and graduates are deemed reasonable, but the expansion of such criticism is inappropriate [1]. - The author clarifies that they are not a hero in the PUMC incident and that Professor Wang Chen is the true hero for his courage to reform in a declining institution [2]. - The author acknowledges past criticisms of PUMC but refutes claims of it being "chaotic" and recognizes its historical excellence [2][3]. Group 2: Institutional Issues - The issues of nepotism at PUMC are historical, stemming from practices established over the past 30-40 years, rather than recent developments [4]. - The resistance from PUMC towards Professor Wang Chen's reforms is noted, highlighting a dismissive attitude from the institution's older faculty [5][6]. - The decline of PUMC's faculty quality post-2000 is attributed to the aging of senior professors and the majority of graduates choosing to study abroad [6][7]. Group 3: Reform Initiatives - Professor Wang Chen's 4+4 educational model is presented as a significant reform that breaks the monopoly of Tsinghua University on admissions and allows for a broader recruitment of talented students [6][8]. - The article argues that the 4+4 model is appropriate for PUMC and should be implemented in other medical schools in China, emphasizing the need for strict adherence to meritocracy [15][20]. - The author stresses that the 4+4 model aligns with the American educational system and is adaptable to modern interdisciplinary needs, such as incorporating artificial intelligence into medical training [18][26]. Group 4: Historical Context and Comparisons - The historical excellence of PUMC in the early 20th century is contrasted with its current challenges, noting that external factors and internal cultural issues have contributed to its decline [10][14]. - Comparisons are made with Peking University and Tsinghua University, which have surpassed PUMC in various fields, including life sciences and basic medical education [13][21]. - The article concludes that while PUMC has a strong foundation, it must adapt and reform to regain its former status in the medical field [14][26].
