说《滕王阁序》"时运不齐,命途多舛"

《滕王阁序》"时运不齐,命途多舛"当依正仓院本改作"大运不齐,命涂(途)多绪",意思说天时运行参差不齐或天时在同一时段对万物的影响不一致,人生之路复杂多样.《滕王阁序》的主旨之一是感叹人生复杂,祸福难以预料,而非单纯的"怀才不遇".

论《程氏易传》中“才”之观念——程颐对易学中阴阳观念的创新

"才"是程颐在释《易》时所使用的独特概念。从根本上说,"才"来源于《易传》中的阴阳观念。但程颐在使用这一观念时摆脱了以非统一、即对立的关系来理解传统的阴阳,而是在一种更独立的意义上去使用阳或阴的观念——"才"。在《程氏易传》中,"才"象征着某种不屈于人生欲望的克己能力,同时它又是某种在政治生活中拯救时局的才能。可以说,"才"之观念反映了程颐易学的某些特色。

从“花果山”到“大观园”——理想人生与社会现实之比较

《西游记》中的孙悟空在花果山自由自在的生活,后来幸运地走上取经的道路,西行途中得到众神的慷慨相助,最终既为社会作出贡献也实现了自己的人生价值。孙悟空的人生经历体现了在明代心学思想影响下,以吴承恩为代表的文人士子对人生的美好憧憬。《红楼梦》中生活在大观园的贾宝玉,向往纯情任性,厌恶仕途经济,却被家庭责任、父命母爱、家族利益牢牢束缚,最终绝望弃世。贾宝玉的人生姿态体现了在清代严苛的社会文化背景下,遭受家庭巨变的曹雪芹对现实社会的理性思考。

试论东林党人在晚明政治生活中的作用

东林党形成于明代万历年间，以顾宪成，高攀龙为领袖的江南学者、官员组成的一个政治派别，其成员主要是一些在野或下野的士大夫。他们笃信“修身齐家治国平天下”的儒学格言。但是他们一的活动未能改变明代行将灭亡的厄运，只是给后人留下了“党人碑后勒遗文”的启迪。

The Temporal and Spatial Evolution Characteristics Analysis of Jiangsu Tourism Economy

[Objective] The paper aimed to reflect the spatial pattern and temporal and spatial evolution characteristics, the differences between inter-regional tourism economy was measured from the quality aspect, which provided a reference for the local governments in the future tourism development. [Method] Using the location entropy methods, three time periods side of tourism-related date of 2000, 2005, 2007 were selected, from the angle of the spatial pattern and the evolution of the differences within the different scales, the spatial and temporal evolution characteristics of the economic development level of Jiangsu were analysed. [Result] The results showed that from the aspect of spatial evolution pattern, as time goes on, the economic development of Jiangsu tourism has experienced morphological evolution of concentration- dispersion decrease-stability; when it comes to the development of the tourism economy, in recent years, the overall gap between the tourism economy in Jiangsu did not widen, the gap mainly led by the region one after another. According to their volatility, it will be divided into four categories: A Stable type (Wuxi, Xuzhou, Lianyungang and Taizhou), B Increasing type (Huai’an), C Fluctuations type (Nanjing, Changzhou, Suzhou and Yangzhou) and D Depression type (Nantong, Yancheng, Zhenjiang and Suqian). [Conclusion] Location entropy was quoted into tourism economic analysis, the method was simple and easy to understand, the result was accurate and convincing, which provided a reference for travel economic development and investment decision-making of Jiangsu.

西来何所为,孤剑托知音 三秦:哭笑不得的帮闲岁月

开元十八年（730）,李白西入秦海,到长安谋事业,然而事与愿违,遗憾而归。天宝元年（742）秋,李白再次应诏入京,这回终于如愿以偿地被召见于金銮殿,但在度过三年翰林岁月后,再次悻悻离开。如今还有种新观点,认为天宝十二年（754）,李白第三次来到长安。这次前来是为了向朝廷告发安禄山造反之事,同时进献济时之策,以便消除这场大乱,尽管他和小友杜甫经过许多努力,却最终报国无门,失望而归。当然,这种说法目前还没有得到有力的史料支撑,尚处未定论阶段。李白一生走过无数地方。

Spatial and Temporal Variability of N, P and K Balances for Agroecosystems in China

Nitrogen, phosphorus, and potassium balances for agroecosystems in China from 1993 to 2001 were calculated at national and provincial levels using statistical data and related parameters, and their spatial and temporal variabilities were analyzed with GIS to estimate the potential impacts of nutrient N, P and K surpluses or deficits to soil, water and air. At the national scale, the N and P balances from 1993 to 2001 showed a surplus, with the nitrogen surplus remaining relatively stable from 1997—2001. Although during this period the P surplus pattern was similar to N, it had smaller values and kept increasing as the use of phosphate fertilizer increased year by year. However, K was deficient from 1993 to 2001 even though from 1999 to 2001 the K deficit decreased. The spatial analysis revealed higher N surpluses in the more developed southeastern provinces and lowest in the western and northern provinces where there was less chemical fertilizer input. The serious K deficit mainly occurred in Shanghai and Beijing municipalities, Jiangsu, Zhejiang and Hubei provinces, and Xinjiang autonomous regions. For the years 1992, 1996 and 2001, N surpluses and K deficits had significant positive spatial correlations with per capita gross domestic product (GDP), per capita gross industrial output value, and per capita net income of rural households. This showed that the level of economic development played an important role on nutrient balances in the agroecosystems.

Extraction of Basic Trends of Urban Expansion in China over Past 40 Years from Satellite Images

If urban sprawl is to be avoided in China in the next ten years, it is not only crucial to understand the overall history, current status, and future trends of urban expansion there, but also these differences, and this is presently lacking. In this study, remotely sensed images with approximately 30 m spatial resolution were used to quantitatively assess the spatial and temporal patterns of urban expansion of 60 Chinese cities(1973–2013). Urban-expansion-process curves of the cities studied were drawn using annual expansion area as an indicator. Curve similarity analysis generated four basic process modes of urban expansion in China. These included cities that: 1) peaked around 2004 and then decelerated; 2) peaked around 2010 and then decelerated; 3) showed sustained acceleration, and 4) showed continued deceleration. Four basic process modes represented cities under different levels of development stage. Geographic location was found to be the most related characteristic to urban expansion process. Regional development policies at the national level in each region also showed highly temporal consistency with fluctuation characteristics of urban expansion process. Urban characteristic such as population size and administrative level were not found to be significantly related to urban expansion-process modes. Understanding the basic process-mode categories well is extremely important for future regional-balance planning and development of macroeconomic policies.

The Impact of Temporal and Political Context on Institutional Change

In order to gain a more comprehensive understanding of institutional change, researchers need to go beyond a snapshot view of significant events but consider events in their temporal setting. Pierson （2004） advocated that the events that lead to institutional change should be placed in a moving temporal context, as this will not only add to our comprehension of the dynamics of change, but also enrich the existing research and enhance the theories we employ to give meaning to these events. Pierson （2004） laid the foundation for the research that was later developed by Thelen （2009） that considered incremental endogenous shifts in institutional thinking that can often result in fundamental transformations. The central issues of Pierson＇s （2004） thesis lay in his interpretation of history and its relationship with path dependence. He claimed that once an institution has chosen a particular path to follow, it can become locked into that pathway and so the options of choice are restricted. This then presumed that an institutions first choice of action is crucial to whether they become locked into a successful course of action or not. The result of the first choice being successful or not would be dependent on the presence of increasing returns. The explication Pierson proffers of increasing returns is different to an economic one in that it is based on positive feedback processes and politics in time. The implications of Pierson＇s work and those that followed have a very serious place in our understanding of institutional change.

Economists’Judgement on China’s Socio-Economic Development in the 14th Five-Year Plan Period

2020 is the final year of China’s 13th Five-Year Plan period and an intersection between the“two centennial goals.”It is also a vital year for drafting the 14th Five-year Plan and embarking on a new journey of socialist modernization.What socio-economic progress has China achieved during the 13th Five-Year Plan period and what are the opportunities,challenges and countermeasures for the 14th Five-Year Plan period?In May 2020,the China Economist conducted a questionnaire survey among economists.Results suggest that during the 13th Five-Year Plan period,China has achieved remarkable progress in the following areas:significant socio-economic development,deepening industry-ICT integration,and rapid growth of new economy;mass entrepreneurship and mass innovation,and enhanced R&D capabilities for cutting-edge technologies;green production and the abatement of air and water pollution;and poverty reduction.In the 14th Five-Year Plan period,opportunities co-exist with challenges for China’s socio-economic development,which brims with resiliency.Surveyed economists felt sanguine about China’s development outlook.Based on the results,surveyed economists believed that the Chinese government should focus on the following priorities during the 14th Five-Year Plan period:expediting industrial transition,strengthening the real economy,and exploring domestic consumption potentials;ramping up research in fundamental science,and accelerating the research of critical technologies;increasing equal access to basic public services;and promoting green development in all respects,including green consumption,production,distribution,innovation,and finance.

Residents′Activity-travel Behavior Variation by Communities in Beijing,China

China's transition from a planned economy to a market economy has resulted in many changes in its urban structure and society and provided an opportunity for a quasi-longitudinal case study on the relationship between the built environment and activity-travel behavior.This paper draws upon data from an activity diary survey conducted in Beijing in 2007.The survey sample comprised 652 residents living in Danwei(work unit),commodity housing,and affordable housing neighborhoods.On the basis of the three-dimensional geo-visualization analysis of the space-time path and statistical multivariate regression models of daily travel and leisure time,it was found that both residential spatial factors and socio-demographics influence residents' daily behaviors.The findings show that Danwei residents have less daily travel time than those who live in commodity housing,but people living in affordable housing endure the longest travel time.Daily leisure time is associated more with individual attributes.We argue that although China's transition is currently gradual,the Danwei system may continue to play significant roles in daily life,and it might provide a valuable model for neighborhood spatial planning.

Spatial and Temporal Pattern of Urban Smart Development in China and Its Driving Mechanism

Smart urban development is an inevitable choice, and is essential to overall strength improvement. It is important to explore an urban smart development path which unites smart growth with driving shrinkage perfectly in forming scientific and sustainable development concept and responding to new normal strategic opportunities. Based on statistic data of 294 prefecture-level cities and above in China from 2000 to 2015, we analyzed spatial and temporal evolution of urban smart development in China by constructing a dynamic fitting model of urban land expansion, population growth, and economic development as well as the coefficient of variation of urban smart development(CVSD). Further efforts were then made to consider differential distribution regularity of urban smart development so as to understand the driving mechanisms of heterogeneous classification of urban smart development in China from different scales and scale variation. Our results indicate that: 1) the disordered growth tendency of urban cities in China is overall well controlled in the middle, and late research and it mainly presented a doublet coexistence of shrinkage disordered cities and smart developing cities. It is particularly obvious that Northeast China and East China have regarded shrinkage disordered cities and smart developing cities as main development tendency separately. 2) Areas with basic stability and relative variation were relatively dispersed across the time period, but the proportion was far beyond areas with significant variation. It demonstrates a relative equilibrium spatial and temporal differential evolution pattern of prefecture-level cities and above in China, except for Tongling, Lanzhou and Chaoyang. 3) prefecture-level cities and above in China are mostly characterized by shrinkage disordered and smart development classification under the background of different scale and scale variation from 2000–2015; however, the spatial resonance relation is not obvious. 4) There are many interaction factors forming an important driving mechanism in developing the spatial and temporal pattern of urban smart development in China, including natural geographical factors, industrial structure adjustment, human capital radiation, regional traffic accessibility, and government decision-making intervention.

Migration Effects to the Marine Ecosystem of Barangay Concepcion

Concepcion is one of the small island barangay in the municipality of Agutaya. It has a total landmass of 132.297 hectares. It is located within Quinluban group of islands. This place has the variety of natural resources like seaweeds, turtles, fish and other seafood. The prominent product in this island is ＂agar-agar＂ also known as Tambalang （local name） and other marine resources. This study determined the effects of migration to the marine ecosystem of the place. Survey method and interview schedule were used during the data gathering. Results show that most migrants came to plant seaweeds or agar-agar. Poverty motivated them to migrate in the area. The abundance of marine resources also is one of the factors for migration for these people. They experienced poverty and economic crisis in their previous place which motivated them to explore and migrate to support their basic needs.

The Study of the Market Economy Problem by the Method of Econophysics

The article considers the econophysical analysis of the relationship between monopoly and competition by using the methods, terms of physics. And it was investigated the philosophy of progress. It has been shown that in the transition from absolute monopoly to imperfect monopoly, the system becomes more complex, and its output characteristics depend on time, because monopoly is a natural, competitive is derivative process. Competition is created as a result of the interaction of at least two ~monopoly firms＂ through the ~market field＂ that they create to increase the production which is necessary of non-linear products over time. To do this, it is sufficient to have a multitude of firms interacting with each other under the influence force of ~market field＂. To create the necessary conditions, it is sufficient to have a high level of university education and a legal field for competition and unbreakable antitrust legislation. By acquiring technology and creating conditions for competition in the market, it is possible to achieve progress even without having a strong science. The term ~progress＂ has received a new content and is defined as the value of a numerically equal increase in the rate of production per unit time or production per squared time. It has been shown that the relationship between monopoly and competition is very simple and there is no contradiction between them. Initially, the market is born as a monopoly, and then analogical firms were created, competition between firms begins

The Role of the Project Manager in Construction Projects in India

In India, the construction industry plays an important role in the economy of the country. It employs a sizeable portion of the work force, contributes largely to the gross domestic product （GDP） of the country, and is seen as a key catalyst for the growth and development of the Indian economy. The industry, however, is beset with many challenges, including delivering projects within projected costs and delivery dates and at the right quality to increasingly discerning clients. It is because of this that project management has assumed so much importance with the project manager seen to be a critical resource in the project achieving its objectives. However, the role of the project manager is still ambiguous. These research hypotheses that the role the project manager ought to play is that of a leader. It is only when project managers assume leadership roles that construction projects achieve objectives measured against time, cost, quality, and customer satisfaction. A quantitative approach was followed in this using both theoretical and analytic methods. The theoretical studies revealed the qualities, skills, and competencies that a project manager ought to possess and the links between the project manager assuming a position of leadership and the project achieving its objectives. The main data collection tool in the analytic method was an online questionnaire administered to 20 project managers of construction projects in India. It was found that while the Indian construction industry does recognize the significance of project managers, their role is relegated to administrative, monitoring, and supervision tasks. There is an overwhelming focus on technical skills. In those cases, where project managers were involved in all the stages of the project and possessed a gamut of managerial, technical, human, and interpersonal skills, there were substantial differences in terms of time, cost, quality, and customer satisfaction in the projects administered by them. The importance of this research stems from its alerting the construction sector in India to the true role that project managers ought to play. If it serves in a shift in the perception of the role of the project managers, this research would have served its purpose.

Measuring Chinese Marine Environmental Efficiency:A Spatiotemporal Pattern Analysis

Environmental efficiency standards are often used to evaluate the costs of oceanic economic development. A variety of statistical analyses were applied in this study to quantify the marine environmental efficiency of 11 Chinese coastal provinces and municipalities between 2000 and 2014. Results initially reveal that environmental efficiency measures that incorporate undesirable outputs are more consistent with real production conditions and thus the use of marine economic and environmental efficiencies supplement and complement one another. Second, overall marine environmental efficiency across China tends to be low and can be spatially characterized by a transformation such that the inefficiencies noted in 2000 have subsequently been transformed to comprise a three-tiered structure that encompasses northern, central, and southern cores. Third, variation in absolute and relative marine environmental efficiency differences for the coastal regions of China have been consistent over time; values initially decreased before increasing again in a fluctuating manner over the time period of this analysis. Fourth, data show that the Pearl River Delta area has experienced the highest rate of change in marine environmental efficiency over time when economic zones are used as basic research units, although values have nevertheless fluctuated significantly. Fifth, values for total factor productivity as well as technical efficiency and change across the Chinese marine economy all fluctuated over time but increased. Data show that changes in marine environmental efficiency across China can primarily be attributed to progress in marine science and technology. Finally, levels of capital investment and marine industrial pollution intensity are not significantly correlated with marine environmental efficiency. Indeed, both marine industrial structural levels and environmental protection technologies have had a positive effect on environmental efficiency while levels of investment in marine scientific research as well as the scale of economic development, the marine economy, and the degree of external openness have all exerted negative effects on this key variable.
