Newsvendor problems for innovative products with budget constraint is studied based on the one-short decision theory. First,one-short decision problem with constraint conditions is proposed and points out the differences between focus points of the one-short decision problem with constraint conditions and focus points of the one-short decision problem without constraints. Then,a newsvendor problem with budget constraint of a new product with a short life cycle is used to illustrate the process of the one-short decision problem with constraint conditions. This example is also compared with the newsvendor problem without constraint.
Estimating of the test quality is mainly determined by the relationship between the items and persons' responses. Rasch model as an idealized mathematical model can be used to evaluate the quality of the items by the fitting degree of empirical data and models. Factor analysis as a statistical method of the classical test theory can be used to assess the level of test quality by the loading data and goodness of fit,but it's not objective and interval. Using the two methods to analysis mathematics test of a high school in Guiyang,and the result provided that Rasch model has more advantages in the analysis of test quality.

It would have a great significance to describe the characters in Lao She'sRickshaw Boyfrom the perspective of criticism on awareness of rogue,the national evil,in today's society.
Marxist philosophy is a revolutionary change in the history of philosophy. The value theory of Marxist philosophy is a revolutionary change in the history of value philosophy. To show the value theory revolution of Marxist philosophy scientifically,it must be based on the social premise of people's free all- round development which is the highest value statement of Marxist,namely,the historical evolution of people's existing pattern. It must abandon the theory of meeting needs that is subjectivism value theory Marx explicitly opposed,and many scholars in China has made various analysis and criticism,but has been still filled with textbooks of Marxist philosophical principles since the 1980 s.
In his fiction,Kazuo Ishiguro portrays a series of orphans. Some of them fall into orphanage due to the war or parental death,and others will themselves to beexilicorphans. These orphans are a metaphor of the inevitable experience in individual growth,that is,everyone needs to face the world as an orphan. At the same time the orphan image embodies the theme of diaspora in the context of contemporary multiculturalism and globalization. Ishigurian orphans thus acquire the cultural import of postcolonialism and postmodernism.

The authors studied Chordate,Mollusca and Mrthropoda communities in the First and Seventh caves of Baiyangping in Guizhou province,A total of 871 cave animal specimens including 363 from first cave in Baiyangping and 508 from seventh cave in Baiyangping,which were belonging to 25 species,20 families,were collected. Through research of cave community in cave,the highest index of diversity was community B( 2. 444 1) and E( 2. 432 6),and the lowest was community A( 1. 875 9).In two caves of the same belt,the similarity index is the highest,and the diversity of community were correlated in every community.
The ethnic minority education is a new and immature subject which needs to be feed with essence and nutrition from other subjects. History has been developed for a hundred years and shaped its own particular theory and methodology that could set a precedent for the ethnic minority education studies. This paper introduces the basic theory and method of history so as to explore and rethink its enlightenments in terms of ethnic minority education studies. Some references can be adopted such as theoretical thinking of considering historical fact,constructing ontology,applying literature analysis and oral history method. Only if ethnic minority education studies learn from others readily and absorb all useful ideas,it can catch up with ethnic minority education practice.
Researches from 2005 to 2014 are bibliometric analyzed by Cite Space from the perspective of increasing tendency,researching hot points,knowledge base and source institutes. Conclusion shows that compared with research results of foreign database,researches at home featured with their own characteristics,but with fragile momentum,simple theme,weak knowledge base and imbalance capability among regions within our country. This study also found that cooperation between and among the two databases is very limited,and China shows great disparity in researching capability between mainland scholars and Hong Kong scholars. All these should be taken into serious consideration.
To explore the relationship between college students' sense of interpersonal association efficacy and achievement motivation,we recruited 300 college students from a normal university for the present study. The subjects responded to the Scale of college Students' Sense of Interpersonal Association Efficacy and Achievement Motivation Scale. The results showed that: On the whole,we found significantly positive correlation between sense of interpersonal association efficacy and achievement motivation,each dimension of interpersonal association efficacy positively correlate with chasing achievement motivation,and negative correlation existed between college students' interpersonal association efficacy and avoiding failure motivation; Among dimensions of college students' interpersonal association efficacy,the agreeable efficacy,the mood administrative efficacy and altruism efficacy had good prediction for achievement motivation,the agreeable efficacy and self-value can partly predict the motivation of chasing achievement,and the mood administrative efficacy and communicating efficacy have good negative prediction for motivation to avoid failure.
Network space puts profound impact on college studentsu0027 ideological and political quality,and should be lifted to the level of class of Ideological and Political Education. Due to various reasons,educatorsu0027 role in network space has not been fully played and the condition leads to a series of negative consequences. The teachers should actively get involved in network space and play as a thoughts competitor,which is co-determined by the assignment of ideological work and educatorsu0027 responsibility under the network environment. Network space proposes new requirements both for the capability of ideological and political educators and the construction of related supporting mechanism.

The determination of index weight is particularly important in the evaluation of ecological economic coordination. A new weighting approach which combines subjective and objective is proposed in this paper. Firstly,unstructured triangular fuzzy number weighting method is proposed by using the fuzzy mathematics principle in subjective weighting process; the CRITIC method and entropy value method is applied in the objective weighting process,and the final weighting index can be got by fusing subjective and objective weight with the multiplicative synthesis operator. This method is used to evaluate the urban ecological economic coordination of blue demonstration area. Results show that Yan Tai has the largest ecological economic coordination index,Dong Ying and Wei Fang have the medium ecological economic coordination index,the ecological economic coordination index of Bin Zhou is minimal. The experiment proves the feasibility and practicability of the subjective and objective weighting fusion. The evaluation results have important reference value on the ecological environment protection and formulation of regional economic development planning.
