清代中越陆地边境跨境问题管理(1644-1840)

清朝前期(1644-1840年)是中越两国封建社会由盛转衰的时期,殖民者东来,中国周边面临殖民势力的扩张,虽然中越仍保持较密切的宗藩关系,但两国封建政府的边疆意识逐渐增强,对两国陆地边境的出入境、边境贸易、跨境流民、跨境通婚等跨国问题采取了一系列的管理措施,以确保边疆地区的安全与稳定。     

执政党建设与主流媒体的关系及其探究价值

在商务英语教学中应渗透中西文化差异教育

中西文化存在很大的差异,语言是文化的载体,不可避免地映射了中西文化差异。因此,在商务英语的教学过程中,任课教师要潜移默化地渗透中西文化差异教育,让学生了解不同的历史背景、风俗习惯、风土人情和文化传统,这样才能使他们掌握语言的背景、内涵,从而恰当地运用商务英语进行商务活动。

Investigations on the degree of bleaching of quartz OSL signals using modern aeolian dust from western Loess Plateau, China

Optically Stimulated Luminescence signal of quartz extracted from modern aeolian dust with known maximum age (about decades) was analyzed in terms of degree of bleaching. The results of dose recovery tests show that the modified double single-aliquot regenerative-dose protocol with the early background subtraction is robust for dating these modern dusts using small aliquots. Bleaching of these dusts is discussed based on the distribution of De values in histograms, scatter plots of D_e versus sensitivity corrected natural OSL signal and comparison between measured D_e and expected D_e. The results indicate that most dusts were completely bleached but some dusts were not completely bleached. For those incompletely bleached dusts in Lanzhou area, the maximum OSL age overestimation is up to ～1 ka, which might be caused by fast deposition accompanied by heavy sand/dust storms. The research suggests that cautions should be given to OSL ages younger than 1 ka in the western China close to deserts.     

Pragian and lower Emsian (Lower Devonian) conodonts from Liujing,Guangxi, South China

LU, J.-F., QIE, W.-Q. & CHEN, X.-Q., July 2016. Pragian and lower Emsian (Lower Devonian) conodonts from Liujing, Guangxi, South China. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

Lower Devonian (Pragian and Emsian) conodonts are described from the Liujing section in Guangxi, South China, highlighting the phylogeny of early polygnathids and establishing the basis for faunal correlations with deposits throughout the world. Records of Eognathodus kuangi sp. nov. and E. nagaolingensis Xiong increase the biodiversity of the Pragian eognathodids in South China and represent intermediate stages and probably the latest eognathodids in the evolutionary succession from Eognathodus to Polygnathus. During this evolutionary succession, the degeneration of the sulcus (or the flattening of the upper platform surface) is the most important morphological change, especially in the eognathodid lineage. Polygnathus trilinearis, P. pireneae and P. sokolovi are recognized together for the first time in South China. The contemporaneous occurrences of the kitabiformis and sokoloviformis morphs of P. pireneae with P. sokolovi and their respective similarities to P. kitabicus and P. sokolovi suggest that the latter two species are phylogenetically linked with P. pireneae. Evidence from the Liujing section also favours Polygnathus probably having evolved from Eognathodus in a tropical or subtropical area.

Gay-riatrics: spatial politics and activism of gay seniors in Tel-Aviv’s gay community centre

This paper discusses aspects of spatial politics and activism at the municipal Gay Community Centre in Tel Aviv. It focuses on one marginal group within the LGBT community that is active in the centre – gay seniors. Drawing on theories of queer geography, queer gerontology and geographies of activism and social movements, the qualitative research reported here uses in-depth interviews and participant observations to demonstrate how these men construct the space for their activity both inside and outside the centre. On the one hand, this spatial politics shifts along a delicate axis between proximity to the municipality and community hegemony, looking ‘inside’ the community on the one hand. On the other, it subverts and challenges the existing communal order, looking ‘outside’ to the surrounding society. However, these two directions are not necessarily binary; rather, as the paper shows, they stand in a dialectic that holds them in tension. This tension is evident in the ways in which the group operates from within the core of the hegemony, creating a complex non-dichotomous reality that enables politics that acts within – and despite – the mainstream.     

CONSERVATION LAND AMENITIES AND REGIONAL ECONOMIES: A POSTMATCHING DIFFERENCE‐IN‐DIFFERENCES ANALYSIS OF THE NORTHWEST FOREST PLAN

The 1994 Northwest Forest Plan (NWFP) resulted in the protection of over 11 million acres of public forestland in the Pacific Northwest region of the United States. This paper quantifies the amenity effect arising from protected NWFP lands on long‐run community economic growth. Using community fixed effects and postmatching panel regression to control for many sources of bias, we find highly localized and positive amenity impacts on the growth in median income, population, and property values for small communities close to protected NWFP land, as compared to communities far from the NWFP. We find no effect on medium‐sized communities.
