The Geo-imaginaries of potential in Mexico's Burgos Basin

In this paper, we use the geo-imaginary analytic to show how actors utilized narratives of resource potential and speculative economic futures for the Burgos Basin in northeastern Mexico to affect a broader liberalization of the nation's hydrocarbon sector. Our research traces the history of the word “potential” as a discrete and repetitive rhetorical technique used variously to speculate on hydrocarbon production, economic development, regional energy development, and risks associated with the Burgos. We also identify an array of visualizations, what we refer to as ‘conjurings,’ used with narratives of potential to encourage investments in the Basin's development. These include: maps depicting Burgos geologic continuity with productive Texas fields, quantitative forecasts of growing production, visual depictions of private firms facilitating future production, and fracking as a necessary wedge to pry open the Burgos' unrealized potential. Finally, using governmentality, we link Burgos potentiality discourses to socio-political outcomes, including in the early 2000s, when the Basin was imagined as a way to counterbalance the skyrocketing costs of imported natural gas, continuing with the 2013–2014 Reforms, and into the post-Reform oil and gas conference spaces that facilitated financial investing opportunities. We also argue that the current administration leveraged anti-fracking discourse to reverse the liberalization of Mexico's hydrocarbon sector. By drawing together overlapping elements from scholarship into resources, speculation, and governmentality, and by parsing the ways that potential narratives and conjuring tools are deployed, this research contributes to ongoing debates in political geography around natural resources and the geopolitics of the subsurface.     

高句丽与汉魏晋及北族政权的朝贡关系

1—5世纪初,无论是统一王朝时期,还是王朝分裂、政权频繁更替时期,高句丽对中原王朝和北族政权都采取积极朝贡的姿态,朝贡活动呈现出单向、双向、多向的变化,先后向十多个王朝和政权进行朝贡。随着政治形势和朝贡对象的变化,高句丽朝贡活动的目的及其与朝贡对象的关系也有一定的变化。     

Confessional disputes in the republic of letters: Susan Du Verger and Margaret Cavendish

The starting point of this article is an understudied piece of critical exegesis from 1657 titled Humble Reflections Upon Some Passages of the Right Honorable the Lady Marchionesse of Newcastles Olio. An obscure Englishwoman named Susan Du Verger composed this 164-page tract to refute a three-page essay on “A Monastical life” by the prolific poet, playwright, and philosopher, Margaret Cavendish. While there is now a substantial body of work on nuns and convents, this research largely overlooks how early modern women engaged with these topics in a scholarly manner. Along with elucidating the gamut of relevant patristic and ecclesiastical histories that were available in the English and French vernaculars, Humble Reflections provides a prompt for investigating Cavendish’s ideas on ecclesiastical order, ceremonies, and toleration. I propose that Cavendish refused to grace Du Verger with a direct response because her polemic disregarded the unofficial codes of conduct — friendship, transnational community, and inter-confessional co-existence — that were supposed to maintain peace within the Republic of Letters. In conclusion, this essay displays that Cavendish was actually a great admirer of monasticism, though not so much for its role in the spread of Christianity as for its place in the development of natural philosophy.     

Spain and the Partition Treaties (1697–1700)

This study takes an analytical approach to the diplomatic strategy adopted by the Spanish monarchy in confronting the challenge it faced associated with the Partition Treaties that were signed by Louis XIV, William III and the United Provinces in 1698 and 1700. By consulting Spanish sources to complete the understanding of the diplomatic process, this study analyses the political action that Spain mobilized in its defence around 1700 and describes the evolution of Spain's foreign policy as the product of the mistrust that had developed between the main powers of Europe. This mistrust was politically answered by Madrid with Carlos II's last will and other planned measures to ensure the viability of the project that contained a turning point in the policy underlying the alliances of the monarchy. Although, like that of the other powers, Spain's manoeuvrability was restricted, this study concludes that Spain was able to create policy action plans and rationally implement them; moreover, the dynamics resulting from the negotiation and signing of the Partition Treaties led the monarchy to oppose them at all costs and naturally led to the choice of a French heir as its only solution.     

当前高句丽史研究中的几个问题

本认为,经过百多年的研究,高句丽史研究已经有了雄厚的学术基础。在新的历史条件下,为了高句丽史研究的理论形态和实践形态发展得更充分,就应该在研究方法和研究手段上有所创新。进而从联系起来研究、专门化研究、献资料和考古资料的关系、“一史两用”和“双向继承”等方面阐明了对高句丽史研究的认识。     

两汉时期高句丽的封国地位

公元前 37年高句丽在汉玄菟郡高句丽县建国时 ,高句丽人已经在西汉郡县制的管辖之下生活了 70多年。高句丽王被王莽政权贬为侯 ,说明其在西汉末为王国 ,东汉光武帝复其王号 ,也证实了高句丽在两汉时期的封国地位。随着高句丽的发展 ,东汉时期高句丽曾侵扰辽东、玄菟、乐浪等地 ,但这都属于边郡地方的冲突 ,高句丽作为边郡封国的地位没有改变。     

从金富轼的高句丽观看高句丽政权的性质及其历史归属

本文认为 ,朝鲜半岛著名的史学家金富轼在其《三国史记》中 ,虽然把高句丽与百济、新罗同列于“海东”三国 ,进行平行载述 ,在当时的历史条件下是势之必然 ,在情理之中 ,但其高句丽观在《高句丽本纪》最后的论赞中得到了清晰准确的诠释 :高句丽是中国的割据政权。

天然水硬性石灰在不同碳化条件下的水化反应

为了探究不同碳化条件对天然水硬性石灰水化过程的影响,继而认识到养护条件中的碳化作用对天然水硬性石灰早期强度和养护时间的影响,模拟制备了不同碳化条件下的样品,用X射线衍射(XRD)、热重分析(TG)、红外光谱(IR)、扫描电子显微镜和X-射线能谱分析(SEM-EDX)测试和比较养护前后天然水硬性石灰成分、结构、形貌的变化。研究表明,天然水硬性石灰水化生成水化硅酸钙(CSH)、氢氧化钙(Ca(OH)_2)的反应与CSH、Ca(OH)_2的碳化反应同时进行,并且Ca(OH)_2的碳化速率大于水化反应生成Ca(OH)_2的速率。随着养护龄期增加CSH逐渐由细小的针棒状结构生长为粗大的棒状结构,随后又逐渐变短并最终完全碳化为方解石晶型的碳酸钙(CaCO_3)形貌。天然水硬性石灰水化产物的碳化作用能促进其水化反应进程。
