Use of laser-scanning confocal microscopy in the detection of diagenesis in bone

This research demonstrates the value of laser scanning confocal microscopy (LSCM) as a research tool in osteological studies, and diagenetic studies in particular. LSCM combines properties of light and scanning electron microscopy using laser light to excite fluorophores throughout the z-axis, developing a 3-D image. Using differential staining and selecting for specific wavelengths of light, one can image targeted materials. This research is divided into two parts: visualizing bone structures such as proteins and their decompositional products and visualizing diagenesis. Part one of this study utilized pig bones as a means of testing the overall ability of LSCM to fluoresce bone. Twenty-three samples were imaged, including 13 samples from a decompositional study conducted 5 years previous, and 10 “fresh” samples collected from a commercial butcher. This part of the study determined that protein and organic components of the bone could be fluoresced and diagenetic alteration could be imaged. The second part of the study used human samples as a means of imaging and mapping diagenetic alterations. The second part of the study used 13 samples, including 4 clinical, 7 ancient, and 2 modern controls. The pig study used Basic Fuchsin and SlowFade Gold stains, while the human study used toluidine blue. Images were also taken with unstained elements. The results of the non-human study found that a fresh bone fluoresced differently than that of a 5-year subset, while the results of the human study confirmed these findings and determined that the bone diagenesis can be mapped using LSCM.     

合力共建巴蜀文化旅游走廊全力打造川渝合作示范区

《成渝地区双城经济圈建设规划纲要》(以下简称《规划纲要》)明确提出"推动广安全面融入重庆都市圈,打造川渝合作示范区"。建设巴蜀文化旅游走廊是《规划纲要》的重要部分。《四川省"十四五"文化和旅游发展规划》提出,加快建设巴蜀文化旅游走廊,整合红色文化、巴文化资源,打造伟人故里、大巴山旅游环线和嘉陵江、涪江诗画长廊,贯通川东北渝东北生态文化旅游带。广安是邓小平同志的故乡,与重庆文化同源,同属巴文化。国家重大区域发展战略、四川省委省政府决策部署为广安高质量发展明确了前进方向和发展路径。广安坚决贯彻落实党中央、省委决策部署,充分发挥紧邻重庆的地缘优势,坚定实施"同城融圈、优镇兴乡、品质主导、产业支撑"四大战略,全面融入重庆都市圈,打造川渝合作示范区,必然要用好天然联系的文化旅游资源,着力与重庆共建巴蜀文化旅游走廊的重要廊道和发展轴。     

Global scientific production,international cooperation,and knowledge evolution of public administration

Public administration is a discipline with considerable history, and is also a diverse, interdisciplinary field in social science. To analyze its evolution, discover the present research foci, and predict future development trends, this study applied scientometrics visualization technology to evaluate over 72,000 scientific articles from the 1920s to 2020s. This research referred to the SSCI and JCR databases to gather scientific data of the discipline and the journals' impact factor. Consequently, paper citations, cited journals, journal co-citations, author co-citations, authoritative papers, top countries, productive institutes, average references, and research collaboration trends were analyzed on the bases of the published literature. This study found top productive journals in the discipline, discovered productive countries and institutes, present the research foci, and predicted future development trends. Through this study, scientific production, international cooperation, and knowledge evolution mode of public administration research offers a clear knowledge map of the public administration discipline.     

真假之外——浅谈文学与虚构

"文学"这一全然晚近的词在诞生之初,便与虚构有着某种密切而又复杂的联系。这种联系并非现今大众观念中根深蒂固的"文学虚构即虚假"——将自然真实与文学艺术所含有的虚构进行简单化的二元对立——的观念,而是一个更加值得深思与探讨的话题。因此,可以通过探讨文学本质同虚构间的联系来摈弃精神锈斑,在粗略的真假对立之外,尝试追寻属于文学与虚构的另一种答案。     

民事权利在社会治理中的核心地位与运行机制探析

建设法治社会,实现社会治理法治化是中国社会治理的必然选择和战略任务。法治的价值判断和终极价值追求是保护民众的私权利与最大福祉,这就势必要求建构以民事权利的保护为核心的社会治理模式与运行机制。坚持并全面推进科学立法、严格执法、公正司法、全民守法,建设预防、化解社会矛盾的系统化、立体式社会治理运行机制,始终秉持民事权利在社会治理中的核心地位。随着科技的发展,应借助科技支撑赋能社会治理创新,培育推动社会治理的现代化水平。     

房地产市场风险的测度研究——基于35个大中城市的实证分析

提高防范化解重大风险的能力是推动经济高质量发展的必然要求。客观识别房地产风险影响因素,科学评价房地产市场风险,对促进房地产市场平稳健康发展具有重大意义。本文围绕新时代高质量发展这个前提,挖掘具有代表性的评价指标,运用主成分分析法从房地产开发风险、融资风险、价格风险、库存风险、城市环境风险五个维度科学构建房地产风险指数,并对35个大中城市的房地产风险进行了实证分析。运用综合指数测度风险可对房地产风险监测提供支持,并对房地产调控思路提出新的政策建议。     

最高人民检察院第二十三批指导性案例解读

近期,经第十三届检察委员会第五十四次会议审议通过,最高人民检察院发布了以“检察机关依法履职促进社会治理”为主题的第二十三批指导性案例,指导各级检察机关进一步依法履行检察职能,促进社会治理创新,推进国家治理体系和治理能力现代化。现结合相关情况,对该批案例作出解读。     

马克思对黑格尔法哲学的三维批判——对《黑格尔法哲学批判》的解读

马克思对黑格尔法哲学三个维度的批判都超出了政治哲学的范围,具有更广泛的一般哲学意义。第一,批判黑格尔法哲学唯心主义世界观,马克思指出头足倒置既是黑格尔法哲学的特征,也是黑格尔全部哲学的特征,进而确立市民社会决定国家的历史唯物主义观点;第二,批判黑格尔法哲学"发展逻辑",揭示黑格尔辩证法的泛逻辑主义方法的缺陷,马克思走向"在事物自身的发展中揭示事物发展的逻辑"的唯物辩证法的哲学道路;第三,对黑格尔法哲学的自由观的批判,得出自由的实现必须通过无产阶级革命创建新国家的结论,马克思完成了政治立场的转变,为自己确立了创立无产阶级哲学的历史使命。对黑格尔法哲学的批判表明马克思的哲学从世界观、方法论、历史观上都已不同于黑格尔思辨、抽象的唯心主义,也显示出其在实践性、阶级性和革命性上与黑格尔哲学具有根本的区别。《黑格尔法哲学批判》在马克思主义哲学发展史上的重要地位就是使"马克思成为马克思"。
