An unprotected vulnerable relict subtropical conifer-Keteleeria evelyniana: Its forests, populations, growth and endangerment by invasive alien plant species in China

Relict subtropical coniferous forests in China face severe fragmentation,resulting in declining populations,and some are under significant threat from invasive alien species.Despite the crucial importance of understanding forest dynamics,knowledge gaps persist,particularly regarding the impact of invasive plants on vulnerable natives like Keteleeria evelyniana.In this study,we investigated the impact of invasive plants on the regeneration of forests dominated by K.evelyniana,a subtropical relict species in southwestern China.For this purpose,we characterized forest dynamics of 160 forest plots featuring K.evelyniana as the primary dominant species and determined whether the presence of invasive plants was correlated with regeneration of K.evelyniana.We identified four distinct forest types in which K.evelyniana was dominant.We found that radial growth of K.evelyniana trees is faster in younger ageclasses today than it was for older trees at the same age.The population structure of K.evelyniana in each forest type exhibited a multimodal age-class distribution.However,three forest types lacked established saplings younger than 10 years old,a situation attributed to the dense coverage of the invasive alien Ageratina adenophora.This invasive species resulted in a reduction of understory species diversity.Additionally,our analysis uncovered a significant negative correlation in phylogenetic relatedness(net relatedness index)between native and invasive alien plant species in eastern Yunnan.This suggests closely related invasive species face heightened competition,hindering successful invasion.Taken together,our findings indicate that successful establishment and habitat restoration of K.evelyniana seedling/saplings require effective measures to control invasive plants.

Detecting the distribution of and public attitudes to charismatic alien species based on media coverage

Charismatic species are often reported by the media,providing information for detecting population status and public perception.To identify the number and distribution of free-living Black Swan(Cygnus atratus),a charismatic alien species in Chinese mainland and to detect the public and the media attitudes to the species,we analyzed the reports and emotional tendency from media coverage in 2000-2022 using manual reading,crawler extraction and latent Dirichlet allocation.A total of 6654 Black Swans were reported at 711 sites,including 147 individuals at 30 nature reserves.Successful breeding was reported at one-fourth of the total sites,including five nature reserves.The proportion of positive emotional tendency to Black Swans was overwhelming in the reports and was higher than that to alien species in general,suggesting that the public and the media are unaware of the risk of biological invasion.Effective management of invasive species requires the media clarifies the invasion risk of charismatic alien species.Promoting the unity between the harmfulness of abstract concept of alien species and the charisma of a specific alien species among the public help effective management.

The Alienation of Nature in Emily Dickinson’s Poems through the Prism of Taoism

In the poems created by the renowned American poet Emily Dickinson,those related to nature constitute a considerable proportion.However,Dickinson’s attitude toward nature is,in fact,contradictory.On the one hand,Dickinson perceives nature as gentle and kind,akin to a mother.Nature is regarded as“heaven”and embodies harmony.On the other hand,nature possesses its own operational principles and harbors inherent cruelty.According to Dickinson,humans should refrain from excessive interference in the natural order.This article attempts to analyze the similarities in attitude towards nature between Dickinson’s poetry and Taoist philosophy.

Fast tracking alien gene discovery by molecular markers in a late flowering Chinese cabbage-cabbage translocation line‘AT7–4'

Flowering time is an important agronomic trait of Chinese cabbage with late flowering being a primary breeding objective.In our previous work,we obtained Chinese cabbage-cabbage translocation lines that contained several beneficial cabbage genes.Cabbage-specific molecular markers show that these genes were coming from chromosome C01 of cabbage.In this study,we investigated the inheritance of flowering time in a couple of translocation lines and analyzed the transmission rate of molecular markers in the offspring.Consequently,we obtained the late flowering Chinese cabbage-cabbage translocation line‘AT7–4’in which the flowering time was later than that of‘85–1’by about 7 days under 4-week vernalization.Based on previous studies of the genomes of Chinese cabbage and cabbage,we located the cabbage-specific molecular markers that were closely linked at the top of the chromosome A01 in the F2mapping population generated by self-crossing F1s derived from a cross between the translocation line‘AT7–4’and Chinese cabbage‘14–36’.Five flowering-related genes in the alien fragment were found by functional annotation and their molecular markers were developed.This study lays the foundation for the future improvement of Chinese cabbage varieties using A-C translocation lines.

Species and Distribution Characteristics of Alien Invasive Plants in Garden Greenbelt of Shijiazhuang City

[Objectives]The paper was to investigate the garden greenbelt in 30 sample plots such as parks,roads,communities,etc.in Shijiazhuang City.[Methods]The species,abundance and frequency of weeds in the greenbelt of public gardens were recorded through point-line-surface investigation,and typical plants were sampled.[Results]There were 56 species of alien invasive plants in garden greenbelts of Shijiazhuang City,belonging to 44 genera and 20 families.In terms of life form,herbaceous plants were absolutely dominant,accounting for 92.8%of the total.The most alien invasive plants were native to America,accounting for 66.1%of the total.In terms of introduction path,the plants introduced artificially and unintentionally accounted for almost half.The species and quantity of alien invasive plants were related to the size of greenbelt area,the length of the build time of the surveyed plot,the composition structure of greenbelt and the level of green management and protection.There was larger distribution of alien invasive plants in the sample plots with large greenbelt area,long build time,herbaceous-dominated greenbelt and low level of green management and protection.Among the 56 alien invasive plants,3 plants were toxic.From the perspective of invasiveness,the alien invasive plants in the garden greenbelt of Shijiazhuang City could be divided into 5 levels:invasive alien species of malignant consequences,invasive alien species of severe consequences,invasive alien species of partial consequences,invasive alien species of average consequences,and invasive alien species to be observed.[Conclusions]This study will provide a reference for the prevention and control of alien plant invasion,and lay a foundation for the prevention and control of existing invasive plants.

A Grotesque and Thrilling World:Alienation in The Fluted Girl

[Objectives]The paper was to investigate and assess the species,distribution and hazard status of invasive alien plants on the campus of Tongren University.[Methods]A survey was conducted using line survey method,and the risk assessment index system of invasive alien plants was established by analytic hierarchy process(AHP).[Results]There were 11 species of invasive alien plants on the campus of Tongren University,belonging to 8 genera and 5 families.There were 6 species of invasive alien plants belonging to Asteraceae,accounting for 54.55%of the total.In terms of the origin of invasive plants,most of them were native to North America and Europe,accounting for 27.27%of the total.In terms of harmful level,there were no high-risk invasive plants on the campus of Tongren University,but Alternanthera philoxeroides had the highest score and was the most harmful.[Conclusions]The present situation of alien plant invasion on the campus of Tongren University is closely related to the ecological environment of the campus.It is suggested to strengthen the management of campus plants,focus on the prevention and control of A.philoxeroides,and carry out regular investigation of invasive alien plants on campus to ensure the ecological safety of the campus.

教育数字化转型中师生主体性的缺失风险与复归策略

在教育数字化转型过程中,教育主体在与数字化技术的碰撞下面临主体性缺失的风险。文章从主体性概念的哲学探究出发,解析出师生主体性缺失与技术异化问题的内隐与外显现象。师生主体性缺失自然地发生于教学活动中,内隐且难以觉察;技术异化现象具有外显性,代替主体性缺失暴露在观察者的视野之内。基于视角主义理论,从“人”“教育”和“技术”的三重视角和两两关系审视技术异化现象,构建“三位一体”异化关系分析结构。究其异化原因,追溯至一元论和二元论的形而上学根基,通过链式逻辑分别演化出“有机体—环境”和“主客体依存对立”的存在模式,进而衍生出技术意向性和技术不当使用的归因实体。对主体性缺失的现象及原因进行深入剖析,提出主动遵循数字技术的意向性逻辑、借由发展实践修复师生主体性的缺失、超越原有建构模式以回归师生主体性本身的复归策略,以期在推进教育数字化转型中筑牢师生主体性根基。

论数字资本主义时代的技术异化

进入数字资本主义时代,技术与资本最大限度的联袂合谋将人们推入数字化生存境地,数字技术最广程度地渗透和浸润到社会生活的各个方面,最大程度地改变了人们的劳动过程、消费模式和交往范式。资本对技术的调用和技术与资本的合谋催生了技术的晦暗面和技术异化,造成了劳动过程的剥削循环、消费需求的虚假过溢和社会交往的虚拟泛化,将人类社会置于技术依赖和数字化生存的困境。消解技术异化和超拔技术生存困境,需要深刻检审数字资本主义时代的技术异化现象,废除资本主义私有制,拆解和打破资本对技术的调用以及技术与资本的联姻,重塑自由劳动过程、归正消费需求取向和复归社会交往真谛,从而使技术朝向为人的解放和自由全面发展的方向服务。

日常生活中的小事情异化——列斐伏尔《日常生活批判》第一卷解读

在列斐伏尔眼里,历史唯物主义正是人本主义异化史观的具体化,这种观点也会进一步延伸到他对马克思中晚期经济学研究中的异化批判理论的理解中。并且,这种异化批判要从马克思的总体人的观念中获得。与马克思《1844年经济学哲学手稿》中前置的价值悬设——理想化劳动不同,列斐伏尔是捕捉到马克思展望人类获得全面解放后的“总体人”自由发展状态,并将其作为未来目标式的后置目的论牵引。并且他认为,这种总体人的观念恰恰是与马克思后来提出的人类社会从必然王国向自由王国的转换是完全同向的。

基于信任视角的价值对齐探究

从价值对齐的信任意涵与信任样态来看,技术发展对人类提出了更高的要求。其要求作为类存在的人在价值对齐的进程中,必须厘清合作、信任与价值对齐这三者之间的逻辑关系与道德意涵,深刻反思人作为价值性存在的根基何在,充分审视技术信任的顶层逻辑及权重,高度重视信任的反面,警惕价值对齐的非道德现象与异化,积极守护技术语境中的人际信任,避免信任的单向度。因此,应以基于道德的信任校准价值对齐,将人类作为人机(技)信任链构建的出发点和落脚点,才能规避价值对齐的陷阱,走向有效的价值对齐,进而确保人工智能安全。

高校学术权力的异化表征与归正路径

学术权力既是高校办学自主权的重要内容,也是大学组织的基础权力。然而,当前我国高校学术权力的异化现象较为严重,这种异化的负向力量会降低公众对于学术权力的心理预期,进而影响高校治学管理和学术研究顺利运行。高校学术权力异化主要表现在高校学术权力主体异化、高校学术权力活动异化、高校学术权力配置异化及高校学术权力监督异化等方面,高校学术主体道德失范、政府过多干预高校学术管理、高校学术权力行政化色彩和高校学术权力法律地位缺乏独立是造成高校学术权力异化的主要归因。回归高校学术权力的本真要义,应进一步规范高校学术权力主体行为、明确高校学术权力运行规则、协调高校“学术”与“行政”权力关系及健全高校学术权力监督机制。

“教学学术”内涵的异化:现状、成因及对策

“教学学术”概念的提出既为教学地位和职能的复归寻绎到一条崭新思路,也确证了教学作为一种学术研究的价值意蕴。在实践中,“教学学术”却面临内涵异化的风险。目前来讲,“教学学术”的内涵大致被异化为以下四类表现,即优秀教学、教学与科研结合、学术性教学、教学科研化。究其原因是对优秀大学教学属性的片面化理解,对日益多元的教育目标的简单堆砌,“教学学术”成果难以被测量、公开、评价,大学教学管理中技术理性的过度膨胀。建议从“价值追求-角色定位-组织支持-制度保障”等四个维度探索对策。

社会加速背景下青年的生存焦虑与消解路径——基于罗萨的社会加速理论

罗萨认为,社会加速诞生了五种“新异化”,人被精准纳入资本加速增殖环节,加剧了社会分化与竞争,产生了“异化危机”。社会加速也加剧了当代青年在教育、就业、住房、婚育等方面的竞争与压力,引发他们内心深处的焦虑。我们应理性审视当代青年生存焦虑的社会根源,积极完善有利于青年健康成长的制度环境,提升青年适应社会加速的综合素质,培育青年积极向上的社会心态,助力当代青年成长为促进社会高质量发展的主体力量。

网络著作权算法私人执法的异化及其矫正

经由算法赋能、私法制度提供合法性的网络著作权算法私人执法,借助公权力体系肆意扩张,正在架构新的社会关系和催生新的社会规范。算法的设计缺陷和法律规制的缺失使得网络著作权算法私人执法存在异化为私主体的利益实现工具的风险,可能造成对网络用户合法权益的侵犯,具体体现为侵蚀用户表达权利、挤压公众合理使用空间、剥夺用户经济利益等。权力与权利的平衡应成为矫正网络著作权算法私人执法异化的规制目标,循着公权力合理限制私权力、增益私权利对抗私权力的规制思路,通过立法建立限权与赋权的制度体系,具体应建立算法审查制度、基本权利保护责任制度以及算法问责制度,配置用户算法解释权和申诉权等,可激发最大制度性合力,实现多元主体的利益平衡。

二重情境:数字视听文化中的身份构建与认同疏离

数字视听媒介及其文化的发展创造了新的情境,推动用户产生新的媒介实践,但也带来了新的问题和现象,即情境生成逻辑向流媒体用户让渡的转变、情境功能作为交往工具的偏移,以及情境秩序在去公共性过程中权力再结构化的取向。其中隐含着情境之于用户身份构建的二重性:一方面,流媒体用户依据情境构建身份,身份的构建过程进一步激发了情境的创造;另一方面,这些被构建的身份呈现出去情境化的流动趋向,造成了身份与认同的疏离。对此,文章在厘清数字视听文化新情境特征的基础上,阐释流媒体用户基于身份的情境互动过程,以及身份认同疏离的成因及危机。更进一步,文章尝试将新媒介—新情境—新行为的线性模式延展为更具解释力的用户主导循环模式,并提出通过共识的凝聚、公共性的重拾和共同体的重建,推动数字视听文化的良序发展。

数字政府视阈下的算法行政:兴起、风险与法治纠偏

随着数字政府建设目标的确立,算法技术嵌入行政成为一种必然趋势,但是算法在促进行政的同时,也带来了法治价值失序的隐忧。算法基于海量数据运算配置社会资源,辅助甚至独立作出行政行为,或许将会成为行政权行使的中枢性力量。但是,过度依赖算法可能导致强调技术理性而忽视价值理性。算法技术本身所带的内生性风险与算法应用中潜在的风险,暗含着行政权力的“技术延伸”和公民权利被侵蚀的隐患,算法行政遭受合法性和合理性的诘难,数字政府建设与法治政府建设面临耦合困境。为防范算法行政异化风险,政府的数字化必须与法治化同步建设,警惕技术理性凌驾于价值理性之上的观念,并从算法的创制、适用以及事后追责的各阶段构建起算法行政的合法性约束机制,避免“权力—权利”格局的失衡,从而促进政府数字化建设和法治化建设的深度融合。

我国海洋外来生物入侵现状、监管问题及建议

外来生物入侵是指非本地生物(植物、动物和微生物)以自然或人为方式对本地生态系统、人类健康、物种多样性造成危害的现象。外来生物入侵不仅对本地生态系统和物种造成严重破坏,而且会对一个产业、一个地区的经济和社会稳定造成严重影响。文章就部分入侵面积和危害较大的海洋外来生物(包括互花米草、沙筛贝、尼罗罗非鱼、米氏凯伦藻、桃拉病毒)的入侵现状进行综述,并提出海洋外来生物入侵防控存在的主要问题及建议。

脑卒中康复期患者社会疏离、病耻感及生存质量的相关性研究

目的对脑卒中康复期患者社会疏离、病耻感及生存质量进行现状调查、分析其相关性,并探讨生存质量的影响因素。方法选取2022年1月至2023年6月就诊于本院的110例脑卒中患者为研究对象,采用一般资料问卷、一般疏离感量表、社会影响量表、健康调查简表对入组脑卒中患者进行问卷调查。结果共有110例脑卒中患者进入本研究,其中,缺血性卒中82例,出血性卒中28例,年龄48~79岁,平均(54.53±7.45)岁,男性69例,占比62.73%,女性41例,占比37.27%。量表评估结果显示:社会疏离得分(48.58±5.46)分、病耻感得分(70.64±6.45)分、生存质量得分(50.26±6.42)分。脑卒中康复期患者社会疏离得分与病耻感得分间呈现正相关关系(r=0.425,P=0.013);社会疏离得分与生存质量得分间呈负相关关系(r=-0.326,P=0.009);病耻感得分与生存质量得分间负相关关系(r=-0.315,P=0.022)。影响因素分析结果显示:月收入、受教育程度、社会疏离得分及病耻感得分是脑卒中康复期患者生存质量得分的影响因素(P<0.05)。结论脑卒中康复期患者社会疏离水平较高、病耻感水平一般、生存质量水平一般。提示临床护理人员应根据患者具体疾病情况,不仅需要密切关注患者疾病及康复情况,也需要最大限度的降低患者出现的社会疏离和病耻感水平,改善患者可能出现的社会性衰弱,对提高脑卒中康复期患者的生存质量有积极意义。
