中华民族的理想社会及其当代启示

中华民族的理想社会是“大同社会”、“天下为公”,追求理想社会的实践活动促进了历史的发展。中华民族传统的理想社会观念对今人有如下启示：历史告诉我们,理想是我们改造社会的巨大的精神力量,纯粹的理想主义和现实主义都是不可取的;理想社会应该物质文明与精神文明并重,应该既重视制度的作用,又重视人的作用;不应以个人主义为出发点,而应将为己与为人统一起来。

位移边界对2D-FGM板热应力影响研究

考虑不同的位移边界条件,建立了常物性2D-FGM板研究模型,并采用有限元法,得到其冷却瞬态热应力场分布图形。位移边界条件对常物性2D-FGM平面区域冷却瞬态热应力分布影响颇大,在简支和一端固定情况下,2D-FGM板自由边界上的热应力σ_x=0;两端固定情况下,其左右两边界均形成上中下三个应力聚集,应力分布形状和数值都发生了巨大的变化;将四周均设置呈固定约束后,热应力数值增长幅度较两端固定情况时更为明显。此结果为该材料的设计、制备提供了准确的理论计算依据。     

Simultaneous decomposition of the variance by sources and subgroups – new insights

There are two types of decompositions: of linear combinations of random variables into contributions of individual variables (sources) and associations between them, and of populations into contributions of their subpopulations. Simultaneous treatment of the two types is called for, which takes into account the correlations between sources within subpopulations and between subpopulation means. The expected values of the subcomponents are derived and their sensitivity to correlations among sources within groups and among source group means is conducted. An example is provided, in which the correlations contribute 20--25% to total variability. This additional information is hidden when decompositions are not simultaneous.     

Smoothing the difference-based estimates of variance using variational mode decomposition

We propose a variational mode decomposition approach to estimate the variance function in a nonparametric heteroscedastic fixed design regression model. A data-driven estimator is constructed by applying variational mode decomposition technique to the difference-based initial estimates. The numerical results show that the proposed estimator performs better than the existing variance estimation procedures in the mean square sense.     

Fragments of Modernization: Domestic Spaces Indicating Traditional Dialects in a Modern Speech

This article examines the change in Turkish domestic space through modernization and, in particular, the artifact of lace, as a nonchanging object in Turkish home in its relationship with the “traditional” and the “modern” domestic settings. Thereby it investigates how traditional and modern settings are defined in Turkish society and, this leads to a further analysis of the modernization process in Turkey within the scope of Turkish house and its domestic settings. The aim of the article is to analyze lace as an agent, which is an actant of the change in domestic settings, to read the connection between the daily life of people and social lives of artifacts. Therefore, examining the dialogue of lace with traditional and modern domestic settings provides to deconstruct the network of the artifact, the house and the individual during the modernization process that Turkish society has been through. The theoretical perspective of the article relies on a material‐semiotic approach with an emphasis on Latour's Actor‐Network Theory and, the methodology of the article is based on ethnography: It includes observations and semi‐structured interviews conducted with people from different social environments focusing on the meaning and the use of lace in domestic environment.

I'm Not a Bad Mother — Stories of Mothering‐on‐the‐Edge

This article is located in the field of custody and day‐to‐day care, with a focus on experiences of mothering where mothers no longer have everyday care of their children. At the time of writing, tens of thousands of mothers live separately from their children in Aotearoa, New Zealand. However, there is a general perception of rarity associated with non‐resident mothers, partly due to their reluctance to speak of loss of custody. In this article, we develop a theoretical discussion around the inside/outside relationships between non‐resident mothers and their children that informs therapeutic practice. We argue that mothers who live apart from their children are situated at the edge or periphery of their children's day‐to‐day lives and experience this as outside the lives of their children. Nevertheless, mothers' stories speak of qualities of (m)othering that have been born of and nurtured by longstanding and long‐term commitment to their children.     

Homemaking on the streets and beyond

Homemaking is associated with domiciled family life, community, and secure work. Moving beyond this perspective, we explore the experiences of people dislocated from family, community, and work, and their efforts to make a place for themselves. We consider a homeless man's efforts to make a home on the streets of Auckland in the absence of positive social ties, employment, and a domiciled abode. This case draws upon an auto-biographical interview, three photo-production projects and three photo-elicitation interviews with Daniel. We consider Daniel's profound sense of loneliness and efforts at imagining a domiciled home beyond the streets where he can forge meaningful relationships. Daniel is now re-housed, in part, as a result of insights from this research being used in social work practice.
