Decomposition of the main effects and interaction term by using orthogonal polynomials in multiple non symmetrical correspondence analysis

The multiple non symmetric correspondence analysis (MNSCA) is a useful technique for analyzing a two-way contingency table. In more complex cases, the predictor variables are more than one. In this paper, the MNSCA, along with the decomposition of the Gray–Williams Tau index, in main effects and interaction term, is used to analyze a contingency table with two predictor categorical variables and an ordinal response variable. The Multiple-Tau index is a measure of association that contains both main effects and interaction term. The main effects represent the change in the response variables due to the change in the level/categories of the predictor variables, considering the effects of their addition, while the interaction effect represents the combined effect of predictor categorical variables on the ordinal response variable. Moreover, for ordinal scale variables, we propose a further decomposition in order to check the existence of power components by using Emerson's orthogonal polynomials.     

水平井分段多簇压裂缝间干扰研究

水平井分段多簇压裂在现场得到了广泛运用，其压裂过程中普遍存在缝间干扰现象。缝间干扰有助于形成复 杂裂缝网络以提高储层导流能力，但是也会导致起裂困难，甚至形成砂堵。因此有必要对分段多簇压裂的缝间干扰问 题进行研究。对此，基于弹性力学建立了分析多簇裂缝诱导应力的数学模型，从起裂压力、裂缝宽度、簇间距等多方面 研究了缝间干扰对水平井分段多簇压裂施工的影响。模拟结果显示，诱导应力会导致起裂压力升高、裂缝变窄，严重 时将造成压裂施工失败。通过进行分析，给出了起裂过程及延伸过程中缝间干扰的影响关系。分析认为，利用缝间干 扰提高改造体积时应当控制簇间距防止对压裂施工造成负面影响。研究结论对优化水平井分段多簇压裂设计具有指 导意义。     

Dynamics of Young Children's Socially Adaptive Resolutions of Peer Conflict

How do young children negotiate conflicts with peers that result in mutually beneficial resolution and peaceful interaction after conflict? A few studies suggest that when children use conciliatory strategies in conflict, socially adaptive outcomes are more likely to be achieved. The present study explores the relative associations of types of children's conciliatory conflict resolution strategies (i.e., prosocial, compliance‐oriented, solution‐oriented, and verbal clarification/apology) with conflict outcomes to contribute to knowledge of the discrete behaviors that might have salience for conflict resolution training. Socially adaptive conflict outcomes were expected to strongly relate to children's resolution strategies of a prosocial nature as well as to teacher or peer interventions encouraging prosocial behavior or empathy. Sampled conflicts (N = 521) were collected through field observations of 107 ethnically/racially and socioeconomically diverse four‐ to seven‐year‐old children. Logistic regression analyses with bootstrap‐based inference suggested that children's prosocial behaviors in conflict were most strongly tied to mutually beneficial resolution and peaceful postconflict interaction, when controlling for relevant covariates. Other conciliatory strategies varied in their association with socially adaptive outcomes. The hypothesis regarding third‐party interventions encouraging prosociability or empathy could not be examined due to infrequent occurrence. Insights for future research on children's socially adaptive conflict negotiations are discussed.     

‘A great job and a family’: work narratives and the work and family interaction

This article investigated how work narratives of dual-earner families are materially and symbolically configured in discourses of reconciliation of work and home life. Following critical studies of the work–family interaction, this research takes into consideration symbolic and social structures and tries to look into the interrelation of factors such as job resources, job satisfaction, levels of autonomy with the self-esteem and sense of ‘self’ which parents derive from their paid work. Hochschild's concept of ‘emotional culture’ is used to explore how parents' experience of work is intertwined to their occupational groups and how it is associated with different narratives of work–family interaction. This study is conducted through qualitative methods, using in-depth semi-structured interviews on a sample of 27 dual-earner families. The data collected are composed of in-depth accounts that are then examined through the method of narrative analysis. The data indicate that, for divergent occupational levels, work generates different material and symbolic resources, which account for divergent narratives of work and home. The sociological analysis of occupational levels with the associated emotional culture of work and family then provides an exploratory model for understanding the links between social class and work–family interaction.     

Fighting words? Joning as conflict talk and identity performance among African American preadolescents

This study examines how preadolescent African American students in Washington, D.C., used a linguistic practice called ‘joning,’ a style of verbal play similar to ritual insults, in peer interactions. Sociolinguists have focused on how children socialize each other into vernacular styles appropriate for peer group use but often assume that they disalign with social and linguistic norms for classroom behavior. Drawing from a nine‐month ethnographic study that the author conducted in an after‐school program, this article analyzes the structure and function of joning as a vernacular style of African American Vernacular English and its uses in constructing classroom identities. Joning often facilitated student learning, but it was perceived as a socially and physically risky linguistic practice because of its uses as conflict talk in the local community. Focusing on preadolescence as a key stage of language socialization, this article shows how minority students modify peer‐learned linguistic practices to pursue academic success on their own terms.     

Embodied versus Disembodied Information: How Online Artifacts Influence Offline Interpersonal Interactions

This article examines how the sheer volume of personal information recorded and searchable online (online artifacts) has transformed the situated activity system central to Goffman's dramaturgical theories. In‐depth interviews reveal that individuals believe disembodied information based on online artifacts is a more accurate representation of others than embodied information from spatially and temporally bounded face‐to‐face (FTF) processes because they represent how others have behaved over time and are attested by their online contacts. However, the n‐adic structure of online interaction leads to mismatched expectations about whether disembodied information is taken into account during FTF encounters, and consequently can result in embarrassment.     

Intercultural education and communication in second language interactions

This article analyses intercultural education outcomes produced in the setting of teaching Italian as a second language (ISL) in an Italian school. Intercultural education is produced in interactions which are based on specific cultural presuppositions, i.e. expectations regarding learning, role hierarchy and evaluation of student performances. Sixteen hours of interactions associated with ISL teaching in a multicultural classroom were audiotaped, transcribed and analysed. The analysis highlights three ways in which cultural diversity becomes meaningful. First, cultural diversity is constructed as one task of learning. Second, cultural diversity is constructed as conflictive interaction. Third, cultural diversity is constructed as a point of departure for positive school performance. These three ways of giving meaning to cultural diversity reveal a prevailing ethnocentric form of ISL teaching, as a consequence of educational presuppositions which do not take the difficulties of intercultural communication seriously. Recently, ‘dialogue’ has been invoked to address ethnocentrism; however, the conditions of effective intercultural dialogue are uncertain.

Questo articolo analizza l’educazione interculturale prodotta nell’insegnamento dell’italiano come seconda lingua (ISL) in una scuola italiana. L’educazione interculturale è realizzata in interazioni che sono basate su specifici presupposti culturali, che sono aspettative di apprendimento, di gerarchie di ruolo e di prestazioni degli studenti. L’educazione interculturale si occupa del problema della diversità culturale, basata su presupposti culturali diversi che emergono nella comunicazione. Sono state audioregistrate, trascritte e analizzate 16 ore di interazione durante l’insegnamento di ISL in una classe multiculturale: l’analisi ha evidenziato tre modi in cui la diversità culturale è resa significativa. La diversità culturale è costruita anzitutto come compito di apprendimento, in secondo luogo come interazione conflittuale, infine come punto di partenza per conseguire una prestazione scolastica positiva. Questi tre modi di costruire la diversità culturale rivelano una forma prevalente di tipo etnocentrico per l’insegnamento ISL, che è una conseguenza di presupposti educativi che non permettono di prendere seriamente le difficoltà della comunicazione interculturale. Recentemente, si è proposto di usare il ‘dialogo’ per superare l’etnocentrismo; tuttavia c’è incertezza sulle condizioni di un dialogo interculturale efficace.     

“天神赐佑”与“尽人之力”：清世宗“天人感应”理念下的钱塘江海塘工程

雍正初年，清世宗在钱塘江海塘修筑中提出了“一劳永逸”的目标，并且为实现治水目的，在意识形态层面将海塘工程纳人到了“天人感应”理念的范畴。但是，“天神赐佑”、“非人力所能”与“一劳永逸”目标之间存在着明显的逻辑矛盾，从而对塘工修筑产生了深刻影响。意识形态与水利工程的交融，因此成为雍正朝治水政治的一大特点。

试论北宋宫廷花鸟画与民间花鸟画的互动——以易元吉绘画为例

宋代宫廷花鸟绘画承袭五代余绪,以"富贵"为特色的黄氏绘画流派为宫廷主流,以"野逸"为风格的徐氏绘画流派主要流行于民间,但两种风格的绘画在宫廷绘画实践中已有妥协互动趋势。活动于北宋中期的长沙艺人易元吉,既是一位优秀的民间画师,又曾征召入宫廷绘画,开创了宫廷花鸟绘画与民间花鸟绘画成功互动的典范。北宋时期我国传统绘画艺术达到极高的艺术成就与这种艺术上的不同流派之间的互动有着密切的关系。
