Savage Jaguars,King Cats,and Ghostly Tigres: Affective Logics and Predatory Natures in Twentieth-Century American Nature Writing

The emerging subfield of historical animal geography provides an opportunity to trace the origins and evolutions of how affective logics framing the conservation of an animal species are co-constituted through embodied interaction between humans and nonhumans, revealing the dynamic ways in which charismatic species are imagined into and out of positions of priority within conservation agendas. This article takes an interest in the shifting perception of predatory species in the environmental conservation movement in the United States, looking to the appearance of jaguars (Panthera onca) in the work of prominent U.S. nature writers Theodore Roosevelt, Ernest Thompson Seton, and Aldo Leopold in the early- to mid-twentieth century. These human–jaguar entanglements reveal a period marked by dynamic changes in the ways in which interspecies encounters were constituted in place; a layering on of affective logics that reveal the complicated origins, practices, and potentialities at the outset of the modern conservation movement. The resulting narratives and images of predatory nature were taken up into dynamic assemblages of jaguar-ness, influencing the formation of new logics that framed public perceptions of predatory natures and provoking a reconsideration of long-held attitudes and policies toward these species.

Designing a Military Event Gazetteer: The Case of Parachute Operations During the French Indochina War

The study of landscapes is an important area of research in critical military geography. Historical military campaigns themselves are violent events that occur within the context of a landscape. Although the actual events are transitory, they can leave behind a tangible record in the landscape and a memory that will be interpreted by present and future generations. Many small-scale individual operations might leave no lasting imprint on the physical landscape and are only remembered in the experience of those who participated. For these less well-known events, such as operations in colonial conflicts, their existence lies in the textual documents of memoirs, military records, and literature on the history of the associated conflicts. This study explores possible methods for designing and constructing a military event gazetteer for organizing information regarding such military operations. Parachute operations during the French Indochina War were chosen for this analysis because of the role these operations played in the counterinsurgency actions of that conflict. Using the methods developed in this study, it is proposed that through a series of military event gazetteers related to colonial wars of independence, a broader understanding of the military (or violence) aspects of the counterinsurgency strategies used in these conflicts might be achieved.     

Surface Rupture of the 1515 Yongsheng Earthquake in Northwest Yunnan,and Its Seismogeological Implications

The 1515 M7? Yongsheng earthquake is the strongest earthquake historically in northwest Yunnan. However, its time, magnitude and the seismogenic fault have long been a topic of dispute. In order to accurately define those problems, a 1:50000 active tectonic mapping was carried out along the northern segment of the Chenghai–Binchuan fault zone. The result shows that there is an at least 25 km–long surface rupture and a series of seismic landslides distributed along the Jinguan fault and the Chenghai fault. Radiocarbon dating of the ~(14) C samples indicates that the surface rupture should be a part of the deformation zone caused by the Yongsheng earthquake in the year 1515. The distribution characteristics of this surface rupture indicate that the macroscopic epicenter of the 1515 Yongsheng earthquake may be located near Hongshiya, and the seismogenic fault of this earthquake is the Jinguan–Chenghai fault, the northern part of the Chenghai–Binchuan fault zone. Striations on the surface rupture show that the latest motion of the fault is normal faulting. The maximum co–seismic vertical displacement can be 3.8 m, according to the empirical formula for the fault displacement and moment magnitude relationship, the moment magnitude of the Yongsheng earthquake was Mw 7.3–7.4. Furthermore, combining published age data with the ~(14) C data in this paper reveals that at least four large earthquakes of similar size to the 1515 Yongsheng earthquake, have taken place across the northern segment of the Chenghai–Binchuan fault zone since 17190±50 yr. BP. The in–situ recurrence interval of Mw 7.3–7.4 characteristic earthquakes in Yongsheng along this fault zone is possibly on the order of 6 ka.     

京津冀地区历史地震事件时空特征研究*

受环太平洋地震带影响,华北平原地区地震频发,尤其是处于中国首都经济圈的京津冀地区的地震事件备受关注。通过对历史文献资料及地震台网记录中的地震事件统计、分析,重建该地区地震事件历史并获取其潜在的空间分布特征及时间规律,对未来地震事件的早期预警具有重要参考意义。分析结果表明,公元前231年至公元2018年期间京津冀地区发生的1044起地震事件中,以有感地震和中强地震为主,小地震、强烈地震以及大地震发生频次较低。地震记录完整性分析结果表明,除小地震外,其他等级地震记录自公元1400年以来基本完整。在空间分布上,京津冀地区历史地震呈“T”字形分布,沿1条北西—南东走向地震带和1条北东—南西走向地震带分布。在时间上,京津冀地区地震事件呈现出阶段性的变化,在公元1480—1680年间以及1950年以来2个时间段内较为活跃,发生频率较高,频谱分析结果进一步表明地震记录存在45年的复发周期。在月际尺度上,地震事件同样存在季节性差异且多发于夏秋季节,同时地震密集区域在年内呈现出自西向东迁移的现象。最后,根据历史地震事件发生的时间规律,在未来一段时间内京津冀地区仍将处于地震活跃期,存在发生强震的风险。

Long-Term Trends in Photosynthetically Active Radiation in Beijing

A long-term dataset of photosynthetically active radiation (Qp) is reconstructed from a broadband global solar radiation (Rs) dataset through an all-weather reconstruction model. This method is based on four years' worth of data collected in Beijing. Observation data of Rs and Qp from 2005--2008 are used to investigate the temporal variability of Qp and its dependence on the clearness index and solar zenith angle. A simple and efficient all-weather empirically derived reconstruction model is proposed to reconstruct Qp from Rs. This reconstruction method is found to estimate instantaneous Qp with high accuracy. The annual mean of the daily values of Qp during the period 1958--2005 period is 25.06 mol m-2 d-1. The magnitude of the long-term trend for the annual averaged Qp is presented (-0.19 mol m-2 yr-1 from 1958--1997 and -0.12 mol m-2 yr-1 from 1958--2005). The trend in Qp exhibits sharp decreases in the spring and summer and more gentle decreases in the autumn and winter.
