[Objective] This study aimed to optimize the PCR amplification conditions for random ssDNA pool in SELEX technology. [Method] L16(45) orthogonal experimental design was adopted for optimization of five important factors affecting PCR reaction system for random single-stranded DNA pool including Mg2+ concentration, dNTP concentration, amount of Taq DNA polymerase, primer concentration and amount of random single-stranded DNA pool at four levels. Meanwhile, the annealing temperature and number of PCR reaction cycles were optimized to establish the optimal reaction system and PCR procedure. [Result] The optimal combination of PCR reaction system for random ssDNA pool was obtained, with a total system volume of 20 μl containing 2.0 μl of 10 × Buffer, 0.5 ng of random ssDNA pool, 2.5 mmol/L Mg2+, 0.25 mmol/L dNTP Mixture, 0.6 μmol/L upstream and downstream primers and 1.5 U of Taq DNA polymerase; the optimal annealing temperature was 68 ℃ and the optimal number of cycles was 12. Under the above conditions, clear and stable bands with high specificity for random ssDNA pool were amplified. [Conclusion] This study laid the foundation for selection of parameters with higher specificity in SELEX technology. 展开更多

In order to improve the quality of Hunyuan inferior Ca-based bentonite (Ca-Bent), semidry process was used to modify Ca-Bent into superior Na-based bentonite (Na-Bent). The factors affecting sodium-modification were investigated. The optimized experimental parameters are obtained as follows: Na2CO3 dosage 4.0%, ageing time 25 d, briquetting pressure 25 MPa and briquetting moisture 20%. Under the optimization conditions, the modified Na-Bent has a colloid value of 73.6 mL/(3g), dilation of 38 mL/g and water absorption in 2 h (2HWA) of 465%, respectively. The bailing results indicate that the modified Na-Bent pellets have higher drop strength and compression strength than the Ca-Bent pellets. 展开更多

We propose a novel scheme based on clustering analysis in color space to solve text segmentation in complex color images. Text segmentation includes automatic clustering of color space and foreground image generation. Two methods are also proposed for automatic clustering: The first one is to determine the optimal number of clusters and the second one is the fuzzy competitively clustering method based on competitively learning techniques. Essential foreground images obtained from any of the color clusters are combined into foreground images. Further performance analysis reveals the advantages of the proposed methods. 展开更多

African-American writers during the 19th century wrote in the shadow of the prominent romance, sentimental, and domestic fiction. Harriet Wilson's Our Nig (1859) reflects an "alternative social character", for the female protagonist suffers racism in the free North, because she is a mulatto child. Through depicting the life of free blacks, who supposedly lives a better life than Southern slaves, Wilson exposes how she has actually lived and sensed life in antebellum America. According to Raymond Williams (2011), there are two kinds of literary writings. The first represents the general tendency of the age, and he calls it "dominant social character"; representing the majority content of both the public writing and speaking. But, another different literary writing lives in its shadow; one that usually leads the conflicts of the time. It is the "alternative social character"; the literature of the victims of repression and marginalization, produced by the lower class, women, and blacks. They reflected how they were dehumanized, and exposed their suffering and abasement. They also aimed to prove individualism. The novel reveals how racism in the North could be worse than the slavery of the South. This paper shows Wilson deviation from the "her brethren" in writing her novel. It unveils significant truths concerning black women's status in antebellum America. It discusses how the author attempts to correct certain misconceptions through her female character 展开更多

This paper makes the case that education aimed at Hispanic or Latino children in the United States needs to recognize both their linguistic and cultural roots (raices) as well as the educational wings (alas). The reason the author believes dual language programs could benefit all is due to the fact that if done properly, it should promote bilingualism, respect, and equity for all students in the school. Dual language programs are relatively new in the United States. These programs aim to create bilingual, bicultural students without sacrificing these students' success in school or beyond. The goals of dual language are to provide high-quality instruction for language-minority students and to provide instruction in a second language for English-speaking students. Schools teach children through content, with teachers adapting their instruction to ensure children's comprehension and using content lessons to convey vocabulary and language structure. Striving for a balance of half language minority students and half English speaking students in each classroom, dual language programs also aim to teach cross-cultural awareness. Programs vary in terms of the amount of time they devote to each language, which grade levels they serve, how much structure they impose for the division of language and curriculum, and what populations they serve. 展开更多

This study addresses the problem of classifying emotional words based on recorded electroencephalogram (EEG) signals by the single-trial EEG classification technique. Emotional two-character Chinese words are used as experimental materials. Positive words versus neutral words and negative words versus neutral words are classified, respectively, using the induced EEG signals. The method of temporally regularized common spatial patterns (TRCSP) is chosen to extract features from the EEG trials, and then single-trial EEG classification is achieved by linear discriminant analysis. Classification accuracies are between 55% and 65%. The statistical significance of the classification accuracies is confirmed by permutation tests, which shows the successful identification of emotional words and neutral ones, and also the ability to identify emotional words. In addition, 10 out of 15 subjects obtain significant classification accuracy for negative words versus neutral words while only 4 are significant for positive words versus neutral words, which demonstrate that negative emotions are more easily identified. 展开更多

The statistical characteristics of a hydrological data for the purposes of decision making in water resource planning and management is only justifiable if the data has the right attributes. This requires that the data being analysed are consistent, free of trend and being part of a stochastic process whose random characteristics is described by an appropriate distribution hypothesis. The data available for statistical analysis had a lot of missing values which could not be ordinarily filled but required a more comprehensive approach to fill these missing values. The KSOM (Kohonen Self-organising Map) was used to fill the missing runoff data from the Jidere-Bonde, Lokoja and Makundi river sites in the Niger basin. Results from the studies have shown that KSOM is the best tool for filling hydrological data with high number of missing values. After the data had been processed, some statistical applications were used to establish the runoff time-series characteristics of the three river sites of the Niger River basin. The results showed good attributes for all three river sites, except that Jidere River's data exhibited inconsistency. The presence of trend was also established for all three river sites; Jidere River was modelled based on 3-pararneter lognormal, the other two river sites were modelled based on normal distribution probability. The presence of trend and other attributes require that a more stochastic modelling process be carried out. However, the results established give reference for water resource planning and management. 展开更多

This article analyzes the role of the media during the 2011 social protests in Israel, in order to examine why the "Social Justice" protest proved more effective than any other social protest organized previously in Israel. Scholars have shown that media fi'aming has a powerful effect on citizen perception and policy debates. The social protests focused on the political-social-economic policy based on a neo-liberal ideology. They signified the beginnings of resistance to the system and became the focus of public and media identification via reports published by leading Israeli newspapers: Yedioth Ahronoth and lsrael Hayom. Using content analysis, the author explore how the media plays an important role to shape the public perception of how to think and act about the protest. Due to the results, we evident the expand media capacity and influence, and that these effects are mediated in presenting positive and supportive coverage, including connotations and metaphors expressed by means of familiar slogans and events in the collective memory of Israeli society. Additionally, the expression "social justice" that became the protest's slogan, offered a broad common basis with which each citizen could identify, including journalists. 展开更多

The neo-liberal re-positioning of the educational-explorative realm to a vocational market-confinement has already impacted quite heavily on the educational sector in England and Wales and is now being imposed on a European wide scale. However, global as well as European students' protests illustrate that resistance to this ideology is gathering pace, and not only involves students and academics but also reaches wider parts of societies. This paper seeks to demonstrate the need for critical pedagogical practices that seek to sensitise students to the modes of current "conditions of domination". It further suggests critical criminologists to foster and engage in a process of public, intellectual, and intercultural exchange of ideas about education and educational institutions away from merely rationalistic, one-dimensional and profit-orientated ambitions toward a multitude of exchanges about meanings and purposes of such important socio-cultural and political institutions and processes that shape "subjectivities", inter-subjectivities and thus entire socio-cultural and political spheres. Such processes and active engagements are crucial to the agenda of critical criminologists, and perhaps most importantly, vital to the continued existence of a critical criminology that understands itself as proper ideology critique. 展开更多

Discussions about justice in cross-cultural context give rise to assorted theories. In this paper, issues surrounding communalism as a theory of justice in African culture will be examined with a view to show that its principles of care and fellow feeling could be worked out to address the problem of alienation from society characterizing some members of the contemporary African society. Recognition of the social dynamics of human society and relationships is of essence to communalism. As a theory of justice and a world view, communalism describes the human being as "being with others" and what that should be. The expression, "I am because we are, and because we are, I am" is the driving force of the communalistic society. Such a society is characterized by care, love, belongingness, solidarity, and interconnectedness. The aim of this paper is to highlight the manifestations of the idea of justice in communalism using leadership or governance, consensus in decision making, moral rules, punishment for wrong doing, and the equitable distribution of resources. It also aims to show that the communalist idea of justice is integrationist in outlook being constitutive of political and socio-economic elements, which the individual enjoys in practical terms as opposed to the paper rights, which citizens in much of the contemporary societies enjoy. The paper notes that drastic changes have occurred in the socio-economic relations within African societies as a consequence of acculturation subsequent to European colonization and these have had far reaching consequences. 展开更多

Organic lithium-ion batteries(OLIBs) represent a new generation of power storage approach for their environmental benignity and high theoretical specific capacities.However, it has the disadvantage with regard to the dissolution of active materials in organic electrolyte. In this study, we encapsulated high capacity material calix[4]quinone(C4Q) in the nanochannels of ordered mesoporous carbon(OMC)CMK-3 with various mass ratios ranging from 1:3 to 3:1, and then systematically investigated their morphology and electrochemical properties. The nanocomposites characterizations confirmed that C4Q is almost entirely capsulated in the nanosized pores of the CMK-3 while the mass ratio is less than2:1. As cathodes in lithium-ion batteries, the C4Q/CMK-3(1:2) nanocomposite exhibits optimal initial discharge capacity of 427 mA h g^(-1) with 58.7% cycling retention after 100 cycles. Meanwhile, the rate performance is also optimized with a capacity of 170.4 mA h g^(-1) at 1 C. This method paves a new way to apply organic cathodes for lithium-ion batteries. 展开更多

In standard canonical correlation analysis (CCA), the data from definite datasets are used to estimate their canonical correlation. In real applications, for example in bilingual text retrieval, it may have a great portion of data that we do not know which set it belongs to. This part of data is called unlabeled data, while the rest from definite datasets is called labeled data. We propose a novel method called regularized canonical correlation analysis (RCCA), which makes use of both labeled and unlabeled samples. Specifically, we learn to approximate canonical correlation as if all data were labeled. Then, we describe a generalization of RCCA for the multi-set situation. Experiments on four real world datasets, Yeast, Cloud, Iris, and Haberman, demonstrate that, by incorporating the unlabeled data points, the accuracy of correlation coefficients can be improved by over 30%. 展开更多
