“合”与“分”的地理效应及民族个性差异

本文从人文地理学的角度剖析了地理环境对于中国历史上国家统一与分裂的重大影响,暨阐述了通常所说的自然与人文的历史的辩证的关系。高山大川的“长城效应”与各区域民族个性差异形成对国家统一的威胁。但同时也是多民族国家统一体的再造与地域文化发展的前提条件之一。     

Spatial optimisation of fire service coverage: a case study of Brisbane,Australia

In the context of changing demand for fire services, spatial optimisation of fire coverage has attracted little scholarly attention despite its potential to improve emergency response and to inform future service planning for fire stations. Drawing on small area population forecasts, this paper extends the application of the Maximum Coverage Location Model to compute and delineate the spatial coverage of current and proposed new fire stations to align with population growth estimates for Brisbane, Australia. Our results reveal important gaps in fire cover that are likely to emerge as a result of predicted population growth, the spatial patterns of which varies across the Brisbane metropolitan area. We draw on these results to delineate a series of new potential sites for fire stations to ameliorate the reduction in spatial coverage as a consequence of predicted population growth demonstrating the utility of our analytic approach for decision‐making and operational planning in the fire services.     

战后日本三权分立问题研究

战后,日本通过《日本国宪法》确立了资产阶级民主制度的三权分立之原则和形式,但由于世界范围内的趋势、日本政体的问题和自民党的"一党独大"等原因,遂造成三权失衡即行政权急剧膨胀和立法权与司法权遭到严重削弱诸问题。     

民国文官制度的独特创制

在中国古代,主要是通过科举制度选拔国家官员。科举制度废除后,孙中山主张在五权宪法的框架之中,由国家设置考试院,主管文官的选拔、任用和考绩。这一创新的理论实践于民国时期。在民国时期,文官考试制度开始运作和完善,其中的特种考试和检定考试是我国的独特创制。文官的任用、考绩、升调、奖惩、抚恤等制度称作文官"铨叙"制度,与文官考试制度相辅相成。文官"铨叙"制度最为规范,也是我国的独特创制。     

1992年以来我国城镇居民居住消费的变化趋势

1992年之后,我国明确了建立社会主义市场经济体制的目标,城镇住房制度改革取得了实质性突破,城镇居民居住消费发生了深刻变化。居民购房公平自由,私有住房的比重急剧攀升,住房设施日益完善,居住环境不断优化,居住开支迅猛增长,城镇居民居住水平获得了前所未有的提高。然而受不正确的思想观念的影响,在居民居住消费过程中,一些诸如住宅私有率过高、住宅面积过大、一房伴终身等严重脱离实际需要和基本国情的问题日益突出。     

日本右翼势力支持"台独"的历史考察

日本右翼势力对“台独”的支持大体经历了三个时期:战后初期,日本右翼势力是“台独”逆流的始作俑者和首开“台独”运动先河的罪魁祸首;冷战时期,日本右翼势力不仅在中日复交前使本国成为“台独”势力的大本营,而且在中日复交后仍一如既往、不遗余力地支持“台独”;后冷战时期,日本右翼势力支持“台独”不仅变本加厉,而且呈现出民间与政界配合、右翼与政府呼应之特点。     

The inclusion record of fluid evolution,crack healing and trapping from a heterogeneous system during rapid cooling of pegmatitic veins (Dronning Maud Land; Antarctica)

Granitoid (pegmatite and aplite) veins in metamorphic rocks and intrusive syenites of central Dronning Maud Land, Antarctica, are flanked by conspicuous light‐coloured alteration halos, which represent the damage zone of fracture propagation. The damage zone is characterized by a high density of sealed or healed microcracks, about 1 order of magnitude above background. Fluid inclusions along healed microcracks in quartz of both pegmatite and alteration halos are inspected by optical and scanning electron microscopy, and their composition is analysed by microthermometry and quadrupole mass spectrometry. The similar inclusion record in the granitoid vein and in the damaged host rock indicates the derivation of the fluids from the hydrous melt phase. The aqueous inclusions bear abundant daughter crystals, mainly silicates, and may represent a hydrous melt. The volatile composition is variable in the system H₂O–CO₂, with mostly subordinate amounts of N₂. Phase separation with partitioning of CO₂ into the fluid phase coexisting with the hydrous melt, and possibly immiscibility in the subsolidus range, govern fluid evolution during cooling. The variable CO₂/N₂ ratio suggests mixing with fluids from an external source in the host rock and vigorous circulation at an early stage of high transient permeability. Experiments have shown that healing of microcracks at high temperatures is a matter of hours to weeks, hence similar in time scale to the cooling of the cm‐ to dm‐thick granitoid veins. In this case, rapid cooling and concomitant crack healing in a system undergoing phase separation causes a broad compositional variability of the inclusions due to necking down, and the underpressure developing in closed compartments precludes a meaningful thermobarometric interpretation.     

Human Response to Climate Change during the Umm an‐Nar/Wadi Suq Transition in the United Arab Emirates

Stable oxygen isotope ratios in archaeological human dental enamel represent an under‐utilised tool in the examination of changing climatic patterns in the ancient world. In the Oman Peninsula at the end of the third millennium bc , rapid aridification was accompanied by a breakdown in interregional trade relations; however, the human response to these changes is poorly understood. At the Bronze Age necropolis at Shimal in the United Arab Emirates, dental enamel from individuals interred in both Umm an‐Nar (ca 2700–2000 bc ) and Wadi Suq (ca 2000–1300 bc ) tombs underwent oxygen, strontium and carbon isotope analyses to examine how local inhabitants of southeastern Arabia responded to both environmental and socioeconomic change. While individuals from Shimal exhibit a clear shift in mean δ¹⁸O_c(VPDB) values from the Umm an‐Nar (−3.5 ± 0.6‰, 1σ) to the Wadi Suq (−2.4 ± 0.9‰, 1σ), corresponding ⁸⁷Sr/⁸⁶Sr and δ¹³C_ap signatures display homogeneity indicative of continuity in Bronze Age lifeways. Together, these data highlight the ability of local communities to successfully adapt to their changing environs (in lieu of societal collapse or a shift to a more mobile lifestyle) in an effort to maintain their way of life.

Second home conversion during the economic crisis: the case of Artemida,Greece

The conversion of second to primary homes is a known phenomenon; yet, its emergence as a result of necessity in an era of economic crisis has not been adequately addressed in the literature. To fill this gap, the article discusses an interview study of younger adults who have made this conversion, conducted in a second home area near Athens, Greece. The study explores the factors that influenced respondents to move permanently to their second home and perceptions of their relocation. Given the ongoing economic crisis in Greece, the research is placed in a unique socioeconomic context, allowing the investigation to delve into the effects of the economic crisis on these housing choices, by comparing perspectives on conversions having taken place before and during the crisis. Findings depict second home mobility as a complex phenomenon linked to tourism, changing housing needs, social factors, economic pressures, but also new potential urban functions arising from the current economic depression in Greece.
