[Method] Biophysical values of four services were monetized within the region, including water regulation, air quality regulation, climate regulation and soil conservation. [Result] The total ESVs were 884.97×10^8 Yuan, 1 302.06×10^8 Yuan and 1 299.49×10^8 Yuan in 2000, 2005 and 2008, respectively. The amount of value per unit area experienced a steep increase from 2000 to 2005(18.10×10^4 Yuan/km2), and then remained almost unchanged from 2005 to 2008 (-0.31×10^4 Yuan/km2). The ESV tended to decline from the southeastern to the northwestern. ESV in the eastern and central part increased faster than that in the south-central and western part of the TRHR from 2000 to 2008. It could be seen that the ecosystem condition of grassland in the TRHR improved signifi- cantly over the study period of 2000-2008. [Conelusion] The results provided good information to assess the effectiveness of current ecological protection measures in the TRHR and support regional sustainable management policies.展开更多

The title of this book is taken from Shakespeare's tragedy Macbeth, implying the multiple themes of the novel. One theme is to discuss the corruption and collapse of the old southern traditional values through the description of the Compson family's corruption and the decline of southern plantation economy. In the novel, Faulkner seeks the way out for American south during the transformation period though the figures he created, but no one is successful in getting out of the bad influence of the Old South.展开更多

The analyses were carried out based on 162 d body mass (BM) of 1 287 animals from 21 paternal half-sib groups of Fenneropenaeus chinensis. Estimated breeding values (EBV) of BM of all individuals were estimated using eight statistical models (A, AB, ABC, ABDC, ABMFC, ABMDC, ABFDC and ABMFDC) and BLUP (best linear unbiased prediction). These models were designed involving factors such as sex, spawn date as fixed effects, maternal genetic effects, full-sib family effects as random effects, mean BM of families at tagging and age at recording (covariate). The results demonstrate the importance of correct interpretation of effects in the data set, particularly those that can influence resemblance between relatives. The data structure and the particular model that was applied markedly influenced the magnitude of variance component estimates. Models based on few effects obtained upward biased estimates of additive genetic variance. The accuracy of genetic parameters and breeding value es- timated by ABFDC model was higher than other models. The results imply that additive genetic direct value, full-sib family effects, and covariance effects besides sex and spawn date as fixed effects were very important for estimating genetic parameters and breeding value of body mass. This model had a heritability estimate of 162 d BM of 0.44. The comparison of the efficiency of selection based on breeding values or phenotypic value revealed great difference: average breeding value of the best 24 families selected by the 162 d BM breeding value and phenotype were 0.577 g and 0.366 g, respectively, representing a 36.57% higher efficiency in the former. In conclusion, selection based on breeding value was more effective than selection based on phenotypic value. Our results indicate that effects influencing the magnitude of estimates should be taken into account when estimating heritability and breeding values for BM.展开更多

In this paper, we studied the long-term fertilizer experiment(started 1980) to assess the soil P dynamic, balance, critical P value and the crop yield response in Taihu Lake region, China. To avoid the effect of nitrogen(N) and potassium(K), only the following treatments were chosen for subsequent discussion, including: C0(control treatment without any fertilizer or organic manure), CNK treatment(mineral N and K only), CNPK(balanced fertilization with mineral N, P and K), MNK(integrated organic manure and mineral N and K), and MNPK(organic manure plus balanced fertilization). The results revealed that the response of wheat yield was more sensitive than rice, and no significant differences of crop yield had been detected among MNK, CNPK and MNPK until 2013. Dynamic and balance of soil total P(TP) and Olsen-P showed soil TP pool was enlarged significantly over consistent fertilization. However, the diminishing marginal utility of soil Olsen-P was also found, indicating that high-level P application in the present condition could not increase soil Olsen-P contents anymore. Linear-linear and Mitscherlich models were used to estimate the critical value of Olsen-P for crops. The average critical P value for rice and wheat was 3.40 and 4.08 mg kg^(–1), respectively. The smaller critical P value than in uplands indicated a stronger ability of P supply for crops in this paddy soil. We concluded that no more mineral P should be applied in rice-wheat system in Taihu Lake region if soil Olsen-P is higher than the critical P value. The agricultural technique and management referring to activate the plant-available P pool are also considerable, such as integrated use of low-P organic manure with mineral N and K.展开更多

Namjagbarwa region, Tibet, was carried out in the period of 1982 to 1984. Samples of aerosol particles were collected by cascade impactor and analyzed for 10 elements by PIXE. Samples of ice, snow and water were collected and analyzed for trace metals, major cations and anions. The pH values of water were at quasi-neutrality or neutrality, and the hardness of water was low. Contents and physico-chemical composition of 20 elements in the major types of soil were determined by physico-chemical methods. Levels of elements in soil varied with soil type and their parent materials. Contents of some elements were higher in the substratum soil derived from in situ than in the surface soil. The region was in a remote area with negligible pollution and could be considered as a good location for measuring the baskground value of environmental sample.展开更多

In this study, we investigated changes in ESV in response to land use changes in Ningwu County, in eastern Loess Plateau of China. Our aim is to provide guidance for sustainable land use planning in this region. We used remote sensing to evaluate land use changes, and applied a fast, proxy-based method for evaluating ESVat three points in time: 1990, 2000, and 2010. More than 89% of the total ESV in Ningwu County was attributable to woodland and grassland. The ESV in western mountain areas show the greatest increase from 1990 to 2010, but ESV decreased the most in the low-elevation northeastern area of flat terrain These tradeoffs led to a slight net decrease (1.0%) in Ningwu County's total ESV. Although the decline in ESV was relatively low compared to the rate of economic growth, total ESV was much lower than global and national average levels at the end of the study period.展开更多

The hypothesis is set that company managers do not have permanent values but they change accordingly to the change in economic conditions: in economical welfare situations business-managers more eagerly take larger responsibilities on ethical and philantrophical stages but in crisis only the lower stages (economical and legal ones) could be detained. In the paper, we firstly observe if values change in general and secondly we study if our pre-stated hypothesis holds. As the research method we use the method of critical incidents展开更多

文摘A study on the elemental composition of aerosol, water and soil in the Mt. Namjagbarwa region, Tibet, was carried out in the period of 1982 to 1984. Samples of aerosol particles were collected by cascade impactor and analyzed for 10 elements by PIXE. Samples of ice, snow and water were collected and analyzed for trace metals, major cations and anions. The pH values of water were at quasi-neutrality or neutrality, and the hardness of water was low. Contents and physico-chemical composition of 20 elements in the major types of soil were determined by physico-chemical methods. Levels of elements in soil varied with soil type and their parent materials. Contents of some elements were higher in the substratum soil derived from in situ than in the surface soil. The region was in a remote area with negligible pollution and could be considered as a good location for measuring the baskground value of environmental sample.
文摘Due to the increasing man-made activities,the vegetation landscape in the rapidly urbanized areas has changed dramatically.Based on the theory of landscape ecology and the evaluation method of ecosystem service function,this study took the vegetation of Shenzhen City as the research object,and used TM image as the main data source in 1985,1995,2005 and from Vol.4 of 2015 with the support of remote sensing and GIS technology to analyze the variation of vegetation landscape fragmentation and its ecological change.The results showed that the vegetation landscape fragmentation in Shenzhen City was significant in the past 30 years,and the vegetation landscape was the main characteristic in the fluctuation trend.The change trajectory of the vegetation landscape was the main focus,and the woodland land area was the largest land for construction.The fragmentation of vegetation landscape reduced the overall value of ecosystem services and hindered the function of life support systems.
文摘Objective:Baccalaureate degree curricula consist of several professional values required for nursing students,which are taught in many ways.This study aimed to explore the perception of baccalaureate Jordanian nursing students regarding professional values and to assess the relationship between students’demographics and their perception of professional values.Methods:The study design was a descriptive,cross-sectional correlational design.A convenience sample of 182 Jordanian undergraduate nursing students enrolled at one of the most prominent universities in Jordan who completed and submitted a self-administered Nurses’Professional Values Scale(NPVS)was considered for this study.Results:The NPVS total score ranged from 37 to 130,with a relatively high total score mean(99.68 with a mean of 3.83 out of 5).The highest score domain in NPVS was“Justice”with a mean of 3.97,while the lowest ranked domain was“Activism”with a mean of 3.69.The correlation coefficient showed no statistically significant correlation between age nor accumulative students’average with a total score of Nurses Professional Values Scale-revised(NPVS-R)and its subdomains.The t test results showed that gender and type of students’enrollment(regular vs.upgrading)did not affect the means of NPVS-R and its subdomains.But differences were found to be statistically significant between the means of first year students and fourth year students in the total score of NPVS-R.Conclusions:Findings of the study alert nursing educators to pay more attention to the importance of promoting the values related to“activism”and“professionalism”among nursing students.Suggestions for enhancing the roles of peer supervision and providing peer review to colleagues would contribute to improving nursing students’performance and raising self-awareness because when nursing educators pay more attention to the items of these domains,better future nursing professionals,leaders,and researchers can be gained.Also,understanding nursing students’perceptions of the importance of professional values and the difficulties in its application would be vital to enlighten educators about the areas that need improvement.
文摘The film——《Gua Sha Treatment》 tells the story of a Chinese family who immigrates to the Unit ed States,but falls into a series of troubles because the traditional Chinese medical therapy-Gua Sha is not understood and recognized by Americans.The film takes Gua Sha as the main line,reflecting the misunderstanding,conflict and integration caused by different cultural values be-tween China and America.This paper interprets the differences and conflicts between Chinese and American cultural values contained in the film from the perspectives of ethics,face and friendship,and points out that mutual adaptation and tolerance are effective meth-ods to overcome cultural barriers and improve the quality of communication in cross-cultural communication.
文摘Different context of mass media between countries can be reflected on the view of family values.In this paper,the author is taking family values as an example to explore the differences between China and America.It is come to a conclusion that mass media have a big influence on family values in both countries.The comparison of different family values also give an inspiration to the development of media industry in China.
文摘An investigation on environmental background values was made in an area of about 1,140,000 km2, which included temperate and subtropical zones of China. The environmental background values of 142 soil environment units, 18 main soil types, 87 surface water environment units, 8 aquatic organism environment units and 20 underground water environment units were obtained. The rules, causes and effecting factors of regional differentiation of the environmental background values were deduced from over 200,000 various data.

文摘Human activities such as the implementation of ecological protection projects and expansion of construction land can cause complex land use changes that affect ecosystem service values (ESV). In this study, we investigated changes in ESV in response to land use changes in Ningwu County, in eastern Loess Plateau of China. Our aim is to provide guidance for sustainable land use planning in this region. We used remote sensing to evaluate land use changes, and applied a fast, proxy-based method for evaluating ESVat three points in time: 1990, 2000, and 2010. More than 89% of the total ESV in Ningwu County was attributable to woodland and grassland. The ESV in western mountain areas show the greatest increase from 1990 to 2010, but ESV decreased the most in the low-elevation northeastern area of flat terrain These tradeoffs led to a slight net decrease (1.0%) in Ningwu County's total ESV. Although the decline in ESV was relatively low compared to the rate of economic growth, total ESV was much lower than global and national average levels at the end of the study period.
文摘With the implementation of the national"urbanization"strategy,the citizenization of migrant workers has become an important part of China's urbanization process.The citizenization of migrant workers not only relies on the institutional reform to promote the exogenous citizenization,but also depends on the dissemination and cultivation of core socialism values,and it transforms traditional migrant workers into real urban citizens.Therefore,it is particularly urgent to strengthen the dissemination of core socialist values to the migrant workers,and it is necessary to systematically optimize the four elements of dissemination subject,dissemination object,dissemination medium and dissemination environment.
文摘The paper deals with the change of management values in Estonian business life in the year of the rapid growth (2007) as compared with the year of hard decline (2009). The hypothesis is set that company managers do not have permanent values but they change accordingly to the change in economic conditions: in economical welfare situations business-managers more eagerly take larger responsibilities on ethical and philantrophical stages but in crisis only the lower stages (economical and legal ones) could be detained. In the paper, we firstly observe if values change in general and secondly we study if our pre-stated hypothesis holds. As the research method we use the method of critical incidents
文摘In the socio-professional environment,the existence of values proves to be essential to the individual in order to live in harmony.It is by the search of oneself that you discover the world around you.Under this aspect,the philosophy of education can contribute to the conveyance of a decisive reflection on the impact of the educator’s mission on the people who are taught.On the one hand,the relativity of values puts into question their universal dimension,since they diversify in place and time according to different eras but also to different customs of each country.In this case,what is the finality of education and learning in relation to cultural diversification with regard to innovation in teaching?On the other hand,the educator’s personality plays a considerable and effective role in motivating his/her target group to seek out the higher and universal values and disseminate the principles of citizenship.Lastly,with regard to vocational training,the introduction of diversified pedagogical approaches as well as the adoption of learning strategies will enable the Educator to act in full knowledge and awareness of his action while being preoccupied in the management of the pedagogical process.His/her effective intervention will offer the opportunity to the group members to create synergies,in order to develop their unexploited potential and achieve a high level of awareness through the development of their personality.
