Relationship between female body size and demographic parameters inBactrocera Malaysian A (Diptera: Tephritidae)

Summary The effect of body size, as measured by the head width, of the femaleBactrocera sp. Malaysian A (kept separately in sexual pairs) on the demographic parameters was investigated in the laboratory under ambient conditions of 28–30°C, 78–85% RH and natural photoperiod. Body size was shown to influence significantly all the demographic parameters. The expectation of life of females at eclosion from pupae was respectively for head widths of 1.6, 1.8, 1.9, 2.0 and 2.1 mm: 76.2, 73.4, 73.8, 102.4 and 115.2 days. The mean number of eggs laid per female in its life time was respectively: 86.4±48.7, 181.8±56.1, 229.7±72.6, 364.3±69.4 and 477.5±109.3 which was significantly different from one another (F=3.73,P<0.05) especially the two smaller sizes from the two larger sizes. The regression line for total eggs laid (Y) against head width (X) wasY=785.2X−1208.7 (R ²=0.35,P<0.001). The net reproductive rate (R ₀) was respectively 15.8, 34.0, 43.5, 66.9 and 88.8 eggs, while the intrinsic rate of increase (r) was respectivley 0.0435, 0.0538, 0.0670, 0.0665 and 0.0711. The results confirm that for mass rearing purposes, larger females which produce more offspring are to be preferred.     

“Show us what you’ve got”: From experiences of undoing to mobilizing agentic vulnerability in research

This inquiry both builds on and extends exploration into gendered research through a focus on researcher vulnerability and its associated ethics. We discuss six critical vignettes across Western and Eastern contexts in which female researchers are “undone” and subsequently “redone” during their research endeavors. We draw upon Butler's work on gender and vulnerability, theorized as a subset of precarity. Attention is drawn to attempts to reframe, understand, and mobilize vulnerability differently, as a form of resistance, research activism, and emancipatory enactment. We propose agentic vulnerability as speaking to felt moments of vulnerability experienced in field research. We extend this contribution into a theorization of the researcher as activist, outlining practical applications of this concept. Ultimately, we seek to reposition agentic vulnerability in institutional research as a source of new ethics, research practices, and activism.     

增加农村公共产品供给是新农村建设的基础工程

社会主义新农村建设的核心是农民增收、生活富裕。农村公共产品的制度外供给加重了农民负担,供给不足影响了农民增收;必须充分认识增加农村公共产品供给是新农村建设的基础工程,对农民增收、缩小城乡差距、化解公共风险、建设和谐社会有重大意义;要通过体制和机制创新,建立“四位一体”供给体制,构建多主体、多层次供给格局,保障有效供给。

触知万物,沟通宇宙——论D.H.劳伦斯诗歌中的触觉

劳伦斯诗歌重视感官意识,其中触觉感知尤其突出.触摸是劳伦斯诗歌中亲子和两性之间爱意的传达,在劳伦斯看来,健康完整的人应当是身体与精神的统一.触觉的最终目的不是肉体的触摸,而是达到触摸人类的情感和灵魂,形成人、环境与宇宙生命之间的沟通和互动.在这个机械和物质文明占主导的时代,劳伦斯触觉意识为生活在“唯我”状态、感知钝化的现代人指出了一条回归完整、和谐与爱的神秘通道.     

浅析汉代“乐府歌行”的萌芽期与形成期

歌行类作品在唐以前就已经出现,到唐代其创作已达极盛。歌行是一个不断变动的概念,在不同的时代、不同论者眼中,其有不尽相同的内涵和外延。正是因为歌行这一诗体的不确定性,推动了人们对歌行的不断探索。这些探索推动了我们对于歌行这一诗体的认识。立足于歌行创作的实践,分别从其萌芽期和形成期的创作情况来分析这一诗体的发展与演变。     

公共健康视域下专利伦理审查机制的问题与对策

危及公共健康的专利的存在,让专利的合理性及合法性颇受质疑,强化伦理审查是提高专利道德合理性及维护公共利益的必然要求。目前我国专利伦理审查面临多重挑战,致使伦理审查流于形式：意识层面上,面临“去伦理化”主张的挑战;立法层面上,立法不完善,缺乏审查依据和标准;实践层面上,审查主体、公众参与及反馈机制不健全。目前可通过厘清观念误区、健全法律体系、引入伦理审查委员会等多种举措来完善专利伦理审查及监督机制。     

试论“身体维权”的行为选择与框架效应

社会转型时期,我国的救济体系由于其强烈的制度移植色彩而水土不服,其对社会矛盾与冲突的化解能力大打折扣。在通过正式制度安排与法定程序无法得到有效权利救济的情境下,当事人往往选择诸如自残自杀等更加＂经济＂和＂快捷＂的维权方式进行身体维权。这些身体维权者的选择过程可以定位为一项有限理性经济人模式下的风险决策过程,行为经济学的框架效应理论有助于诠释身体维权行为的决策过程和行为动机。

“能表达的言语”、“被表达的言语”与身体——早期梅洛·庞蒂的身体性语言观浅析

梅洛-庞蒂在《知觉现象学》中对“能表达的言语”与“被表达的言语”做了区分．这种区分体现了言语和语言的身体性,也揭示了言语表达的特殊性,即可以沉积为独立的语言世界和文化世界。“能表达的言语”和“被表达的言语”的区分虽然没有克服主体和客体的两分法,但却触及到了梅洛-庞蒂中后期哲学的问题,一是“能表达的言语”和“被表达的言语”相互依赖和转化,二是“被表达的言语”同样被赋予身体性。
