Navigating Temporal and Spatial Dimensions:Unveiling the Fictional Essence and Authenticity in the Narrative of The Rise and Fall of Wing Shing Street

The novel The Rise and Fall of Wing Shing Street delves into the reality of Hong Kong residents deeply attuned to spatial awareness but detached from temporal significance,entangling emotions surrounding time and space.Through narrative interruption and extension,the author portrays the genuine struggles of Hong Kong inhabitants-juxtaposing the blurred boundaries of time and space and the inherent rootlessness of reality within a fictionalized framework.Emphasizing the 20th-century human condition,wherein spatial awareness overshadows temporal understanding,the novel underscores the consequences:a loss of history and cultural identity.With a fresh perspective,the narrative explores the interplay of time and space,accentuating both the fictitious and authentic dimensions.This prompts readers to reconsider their history,culture,and the current moment,ultimately highlighting the pivotal role of temporal awareness.

On the Rise and Fall of Great Britain

From the Industrial Revolution to the World War,the past three centuries have witnessed the development and rise and fall of Great Britain.Great Britain,an island country with a total area of about 240,000 square kilometers,enjoys a very important place in the world in modern history.Great Britain was the first industrial country and created the epoch-making laissez-faire capitalism and built a sun-never-set empire.It was also the leadership of the world from the middle of 18^th and to the middle of 19^th century.In retrospect to the rise of Great Britain,we can easily see that it was by relying on an innovative culture that the island country became a great power in Europe and then became the dominant empire in the world.This innovative character permeates in all kinds of culture including industrial,military,technological,politic and diplomatic.As for the main cause of Great Britain’s rise,this thesis attempts to analyze from three aspects,that is,the emancipation of mind,the advancement of military power,and the development of technology.After the World War,Great Britain began to suffer a decline in status and was reduced to a second class developed country.That is also because the conservative factor in its culture which blocks its development and the potential to innovate new things.The past years has witnessed the fall of the empire and also left us much inspiration.Take the history as a mirror,the thesis will focus on the“English disease”and influence of the World War to make an analysis on Great Britain’s fall.A conclusion of inspiration would also be included.

Analysis of a Large Grounding System and Subsequent Field Test Validation Using the Fall of Potential Method

This paper examines various aspects of the design process and subsequent field test measurements of a large and complex substation grounding system. The study and measurements show that soil layering and lead interference can have a significant impact on the appropriate test location that yields the exact substation ground impedance. Applying a specific percentage rule such as the 61.8% rule for uniform soils to obtain the true ground impedance may lead to unacceptable errors for large grounding systems. This poses significant problems when attempting to validate a design based on raw test data that are interpreted using approximate methods to evaluate substation ground impedance, and determine ground potential rise (GPR), touch and step voltages. Advanced measurement methodologies and modern software packages were used to obtain and effectively analyze fall of potential test data, compute fault current distribution, and evaluate touch and step voltages for this large substation. Fault current distribution between the grounding system and other metallic paths were computed to determine the portion of fault current discharged in the grounding system. The performance of the grounding system, including its GPR and touch and step voltages, has been accurately computed and measured, taking into account the impedance of the steel material used of the ground conductors and circulating currents within the substation grounding system.

古代农业帝国兴衰周期律ABM仿真研究——国家兴衰动力学的模型探索

在农业帝国时期,周期律曾经长期地存在,呈现稳健的历史规律。关于导致这种规律的动力学机制,学术界一直好奇、但长期缺乏有效的方法。尽管存在很多理论分析,但难以被数学、模型支撑。基于历史数据的定量分析具有静态性,无法呈现动态演化全过程,本文使用智能体仿真模拟(ABM)方法,以弥补上述方法的不足。秉承历史唯物主义,从科学模型与实证验证角度,揭示此宏观系统规律背后的微观与宏观动力学机制,并通过模拟联通两个层面。基于虎(帝国敌人)、狼(统治阶级)、羊(农民阶级)、草(农业土地)四类智能体,构建国家(社会)有机体的静态系统结构。通过机制设计,赋予智能体自主的行动、互动的能力,实时记录宏观系统层面的状态结果。结果表明,ABM模拟的最优解,能够高度拟合、全程反演从秦汉到明清2132年的国家兴衰大历史轨迹。基于ABM的国家兴衰动力学模型,在当代仍然有镜鉴价值,在国家治理现代化、大国竞争对手预测、特定地区态势预测方面,具有重要应用价值。

Study on the Characteristics ofSeismic Activity in West China andIts neighboring Regions

The controlling and influencing effects of the joint action of plates surrounding China on strong earthquakes in Chinese mainland are discussed, and the characteristics of seismic activities in the West of China and neighboring regions are further studied. The results show that the seismic activity in the West of China and neighboring regions not only has the characteristics of high tide and low tide alternation but also has the characteristics of rising in one region while falling in another, and the rise and fall of seismicity are in some proportion. The above characteristics are useful for the prediction of main body region of strong earthquakes in Chinese mainland, especially for the judgement of the ending time of the high tide period.

Can investors profit by utilizing technical trading strategies?Evidence from the Korean and Chinese stock markets

The idea of this study is derived from observing the profitability of stock investments following the phenomena of continuously rising(or falling)prices of stocks and continuously overbought(or oversold)signals emitted by technical indicators.We employ the standard event study approach and technical trading strategies to explore whether investors would exploit profits in trading the constituent stocks of the Korea Composite Stock Price Index 50 and Shanghai Stock Exchange 50 when the aforementioned continuous phenomena occur.We find that both the Korean and Chinese stock markets are not fully efficient;this finding may enhance the robustness of the existing literature.In addition,we reveal that contrarian strategies are appropriate for the trading stocks listed on the Korean stock market for all the cases investigated in this study.However,momentum strategies are appropriate for the Chinese stock market when continuously rising stock prices and overbought signals are simultaneously observed.These findings imply that the difference in investor behaviors between the Korean and Chinese stock markets might result in dissimilar trading strategies being employed for these two markets.

The Land of Shu:Where Tang Poetry Rose and Fell

During the Tang Dynasty,the land of Shu was composed of the Ba and Shu areas,which were adjacent to present-day Hanzhong city of Shaanxi province to the north,northern Yunnan province to the south,Wushan county of Chongqing to the east,and Xichang city of Sichuan province to the west.In the nearly 300 years of rule under the dynasty,a number of poets,whether they were born or just worked and lived there for a short period of time,wrote many immortal poems,which constitute an integral part of Tang poetry.They range from Chen Zi’ang and Wang Bo of the early Tang to Li Shangyin,Wen Tingyun,and Wei Zhuang of the late Tang.The land of Shu is,therefore,the witness of the rise and fall of Tang poetry.

The Role of Authoritative Leadership in the Rise of Western Great Powers in Modern Times

The authoritative leadership of a country is the legal political leadership approved by the people. Authoritative leadership has played important and irreplaceable roles in the rise of various western great powers in various forms in modern times. However,they cannot promote the development of every country in every period because of the limitations determined by the defects existing in themselves.

Simulating rise and fall cycles of Vietnam empires

The life cycle pattern of empires is pervasive worldwide,and this is caused by multiple factors.In the history of Vietnam,there are totally about ten empires or dynasties,which have aggregately lasted for more than one thousand years.Here,we apply the life cycle model and agent-based modeling to uncover the underlying mechanisms of the life cycle pattern for Vietnam empires.Macroscopically,the man-land relationship greatly shapes the life cycle pattern of traditional agricultural empires.The balancing process between land and population is critical for the empires.The relationship between incomes and costs has determined the actions or strategies of the social members or individuals.It suggests that our optimal solutions and simulations have perfectly matched the real history of Vietnam.Under three optimal solutions,the distributions of simulated and real empire durations in history can be well-matched,in terms of both discrete(histogram)and continuous forms(kernel density).It indicates that the history of human society is a dynamic process,which is determined by certain evolutionary rules and regulations.Therefore,we are able to back-calculate,simulate,and even predict the future of empires or countries.

Factors Determining Health Expenditure in the Asian and the OECD Countries

It is widely recognized that developed countries have been spending more than developing countries on health care. Objective of the study is to examine determinants of health expenditure and what factors influence it. Fifteen Asian countries and 30 OECD countries were chosen to explore the difference of their health expenditure structures. Model of health expenditure per person was estimated to be dependent on market demand, market supply, and other exogenous factors. A model with country specific and time effects of health expenditure was used and estimated. The study found a negative but insignificant relationship between price and health expenditure and a positive and significant relationship between GDP and health expenditure. Urban population density as proxy of urbanization was found to induce the health expenditure in the OECD. Out-of-pocket payment was also found to induce health expenditure for both the Asian and the OECD countries. A net effect of improvement in the health status or a lower mortality rate and a higher life expectancy caused an increase in the health expenditure among the Asian countries studied but decreased health expenditure in the OECD countries. In terms of income elasticity, it was found to be smaller than one in both groups of the countries. Since the income has changed faster than the other factors, the net effect of changes of all factors over period of time will cause rising in health care expenditure. Finally, the model indicated that both the Asian and OECD countries will continue to have a rising health expenditure per person over a period of time.

金沙江支流黑水河松新电站短须裂腹鱼(Schizothorax wangchiachii)过坝后上溯行为

鱼类过坝后的上溯行为对鱼类寻找适宜的产卵、索饵等功能性栖息地至关重要。现阶段我国大多数研究聚焦于鱼类上溯通过鱼道的游泳行为量化,而过坝后的上溯行为分析鲜有报道。本研究在金沙江下游支流黑水河松新坝址处利用PIT(passive integrated transponder)遥测技术对松新电站过鱼对象短须裂腹鱼(Schizothorax wangchiachii)过坝后的上溯行为开展监测,考虑监测过程中水文情势变化对过坝后上溯行为的影响,采用生存分析方法,构建了耦合多因素(流量、水温、河道涨落水率、昼夜节律、肥满度等)的Cox风险比例回归模型,利用AIC模型准则筛选出最优模型参数,识别了影响鱼类过坝后上溯成功率的关键因素。结果表明:(1)短须裂腹鱼在松新鱼道的上溯效果显著优于河道;(2)水温及河道涨落率是影响短须裂腹鱼过坝后上溯效果的关键因素;(3)水温与短须裂腹鱼过坝后河道上溯成功率呈负相关,当水温超过短须裂腹鱼最适温度后,河道上溯成功率随着温度的上升呈递减趋势;河道涨落水率与短须裂腹鱼过坝后河道上溯成功率呈正相关,其中涨水情势下短须裂腹鱼河道成功上溯的概率高于落水,河道上溯成功率随着涨水率增大呈递增趋势;(4)尽管昼夜节律对短须裂腹鱼过坝后河道上溯成功率无显著影响,但从数据结果发现有61%的短须裂腹鱼选择在夜间上溯。本研究旨在为恢复鱼类栖息地和优化小水电生态调度提供科学依据及参考价值。

Uncommon and Impact-Suspicious Geologic Phenomena across Jordan and Adjacent Areas, Arabian Plate

For the discovery and analysis of Jebel Waqf as Suwwan (JWS) Impact Crater, Jordan pushed the authors to consequently focusing on other unusual geologic phenomena such as circular/oval structures (some of “crypto-volcanic” origin), disharmonic folding, horizontal stylolites, and a broad stripe of?Sanidine-Hornfels-Facies, all of them hosted in Upper Cretaceous/Paleogene carbonate rocks exposed across Jordan and adjacent areas. Shatter cones are the most useful tools during field work in the realm of circular structures. In addition to the impact-geologic data of JWS Impact Structure hitherto available, the cooling process of melted Lower Cretaceous Kurnub-Sandstone could be verified by microscopically identified SiO2-modifications between the melting point (1714°C) and low temperatures. In comparison with the Suffield 500 tons explosion tests [20] and with the Ries Impact Crater, Germany, excavation and vaporization processes of target rocks demand drilling between Central Uplift and Inner Ring of the JWS Impact Structure (“Chert-Carbonate-Impact-Chess Game”). In a scenario: “Impacting meets Plate Tectonics”, phenomena like disharmonic folding, horizontal stylolites, and an abundance of circular/oval structures of high diameter variation through northwest Jordan are discussed under aspects of gravitational gliding, effects of seismic surface waves (Love-), transpressional structures related to Jordan Rift-Tectonics, and possible impact processes of unknown number occurred on the Arabian Plate in southeastern direction with northwest-directed impulse. The so-called “Mottled Zone” of Jordan and Palestine owning a high number (~100) of mineral neoformations with formation temperatures up to ~1120°C(pseudo-wollastonite = β-CaSiO3), is to be interpreted as of “Sanidine-Hornfels-Impact Facies” under ricochet conditions along an “Avenue of Ricochet-Impact-Thermo-Cataclysm”. Marble-related travertines represent a low temperature facies of the impact event. The temporal projection of patterns like Rapid Climate Change (RCC), astrophysical data [Hoyle’s Comet: 47], acid events in ice-cores, tektite fall, Rise and Fall of Neolithic/Bronze Age Cultures, reveals an amazing “Ensemble” of coincidences among all of these parameters since the Middle/Upper Pleistocene boundary throughout Holocene. Ten short Interval Cases are discussed as being “Rare Event”- suspicious. Myths like the “Gilgamesch Epos” and “John’s Apocalypse” surprisingly provide realistic hints on impact events comparable with modern observations and experiments, which are: approach of extraterrestrial bodies, impact cratering, earthquakes and faulting, supercyclonic whirl-storms (wildfires), effects of hot ejecta, destruction of fauna, flora, and cities, long-lasting flooding, darkness caused by ashes and dust circulating in atmosphere and stratosphere (sintwinter), and environmental pollution. Such hints were handed down in myths of ~180 ethnic peoples around the globe. “High probability Cases” focus on impact events on ~9600 yr B.P and on ~6000 yr B.P. Other “Rare Events” may have possibly occurred about ~8000 yr B.P. and on ~3200 yr. B.P. (all radiocarbon yr.cal.). Core-drilling in the pull-apart basins of the Jordan Rift System (Dead Sea, Lake Tiberias) as traps having possibly preserved volcanic and impact ejecta would be a challenging international and interdisciplinary project.

Genetic Algorithm Based Speed Control of PMDC Motor Using Low Cost PIC 16F877A Microcontroller

This paper mainly aims at proposing an effective method of speed control of the low power motors like Permanent Magnet Direct Current (PMDC) motor used in the orthopedic surgeries using a natural optimization technique called genetic algorithm. Using this method, better values of Performance parameters like rise time, settling time, fall time, peak overshoot and steady state are achieved compared to the conventional PI controller. The SIMUINK MODEL of both the controller operation is obtained using MATLAB version R2013a. The simulated results reveal that the proposed control drive exhibits reduced peak overshoot, rise time, settling time and steady state error. An experimental setup is devised to validate the simulation results. The comparative analysis made depicts the superiority of the proposed algorithm with reference to its conventional counterpart.

大国兴衰与国际秩序的历史演进

大国兴衰与国际秩序的历史演进有着非常密切的联系。尽管近代以来国际秩序的具体形态不断发生演变,大国之间的力量对比不断发生改变,但欧洲和西方大国始终是国际秩序的主导力量。二战结束之后,摆脱了殖民地或半殖民地地位的非西方大国开始登上世界舞台。冷战结束后,一批非西方大国在新一轮的经济全球化进程中乘势而起,改变了大国之间力量对比结果,促成了“世界百年未有之大变局”的到来。相比于西方大国,非西方大国不仅具有更为广阔和长远的发展优势,更有不同的历史经验和价值追求,从而为国际秩序的发展变化注入了新的活力。而中国提出“人类命运共同体”理念构想和“全球发展倡议”“全球安全倡议”“全球文明倡议”,更是为超越当今世界所面临的挑战和困局,构建更为公正、合理的国际秩序,提供了令人鼓舞的发展目标和前景。

战略科技力量与大国兴衰的逻辑——以二战后美国科技博弈为例

研究战略科技力量如何影响大国兴衰及其核心逻辑,对于维护国家主权、安全与发展利益具有重大的意义。战略科技力量推动大国力量消长,加剧大国安全困境,打破大国内部权力均衡。基于对美苏、美日、美中科技博弈的历史与现实案例的考察可见,美国通过科技博弈巩固了霸权,延缓了霸权的衰落,但同时也对自身带来科技伦理风险、技术治理难题等挑战。战略科技力量博弈改变大国兴衰的内在规律,一些大国因此更深地陷入美国科技霸权体系,甚至有可能跌落成为次要国家。大国战略科技力量博弈是关乎综合国力、政治制度、科技联盟与创新模式的全方位博弈,竞争制胜需要具备强大的国家综合国力、良好的政策弹性与制度优势、科技“盟友”支持及灵活的科技创新模式。

民初新式知识分子重释“天下兴亡匹夫有责”论

民初一些知识分子以报刊为阵地大声疾呼并努力诠释“天下兴亡匹夫有责”。他们赋予此一流行话语以时代新义,其中“天下”与“国家”由异趋同聚合为近代共和国,而“匹夫”则由传统臣民一跃而为近代国民。“天下”与“匹夫”的关系遂转变为国家与国民的新关系。而近代语境下的“匹夫有责”的“责”则凸显为自觉弘扬中华民族传统优秀道义精神,视其为天赋人权精神中应有之义,具体外现为职责、责任、良心与诚信等道德素养,蕴含着浓郁的政治文化与社会文化等价值诉求。这从一个侧面透露出“天下兴亡匹夫有责”渐成中国近代爱国主义的代名词。
