浅析中国古代食具碗造型的发展规律

"碗"是中国古代最主要的饮食器具,其器型称谓经历了多次变化.从材质上讲,它经历了陶器、瓷器、漆器和银器等几个演化阶段;从功能和形式上讲,碗的口径和高度大小均满足东方人对碗的使用要求.这说明中国古代的碗,在前期其功能变化不大,形制也较为单一.随着人们对自己和器物关系的规律性认识的不断深化,器物的型制也从单一走向多样,并逐渐形成了后期比较明确的功能性造型取向,这对现代设计有着启示借鉴作用.     

Relatives in Residence: Relatedness of Household Members Drives Schooling Differentials in Mozambique

Children typically receive investments from their fathers, but absent fathers often invest at low levels. In a father's absence, what types of nonfathers invest heavily in children? This article investigates educational participation as a reflection of childhood investments on Ibo Island, Mozambique, where only one third of school‐aged children live with their biological fathers. Father‐present children generally attended school at the highest rates. Stepchildren and father‐absent relatives (e.g., grandchildren, nieces) attended school at comparably high rates if any coresiding children were father‐present. This may signal high altruism among present fathers toward some nonoffspring. Consistent with this result, a fixed effects model indicates that, within the same household, adult males invested equally in their own children, relatives, and stepchildren. Prejudicially lower investments were made in children who were unrelated to the household's adult males, however; this result has strong negative implications for the well‐being of African children fostered by nonrelatives.     

高校建立固定资产折旧制度探析

一直以来，高校固定资产核算不计提折旧，这种核算方法在实际工作中已经显示出了诸多弊端。为了加强高校固定资产管理，提高固定资产使用效益，本文从高校固定资产不计提折旧的原因人手，分析了高校建立固定资产折旧制度的必要性，提出了相应的会计处理方法。     

Disaster response on September 11, 2001 through the lens of statistical network analysis

The rescue and relief operations triggered by the September 11, 2001 attacks on the World Trade Center in New York City demanded collaboration among hundreds of organisations. To shed light on the response to the September 11, 2001 attacks and help to plan and prepare the response to future disasters, we study the inter-organisational network that emerged in response to the attacks. Studying the inter-organisational network can help to shed light on (1) whether some organisations dominated the inter-organisational network and facilitated communication and coordination of the disaster response; (2) whether the dominating organisations were supposed to coordinate disaster response or emerged as coordinators in the wake of the disaster; and (3) the degree of network redundancy and sensitivity of the inter-organisational network to disturbances following the initial disaster. We introduce a Bayesian framework which can answer the substantive questions of interest while being as simple and parsimonious as possible. The framework allows organisations to have varying propensities to collaborate, while taking covariates into account, and allows to assess whether the inter-organisational network had network redundancy—in the form of transitivity—by using a test which may be regarded as a Bayesian score test. We discuss implications in terms of disaster management.     

高校固定资产折旧制度初探

高校进行成本核算就必须计提折旧，以真实地反映固定资产的使用情况、有形和无形损耗以及作为已投入基建资金的补偿，为人才培养成本提供准确信息。高校应以清产核资为基础，科学合理的建立固定资产折旧制度。     

A formula for a missing plot in a general incomplete block design,when recovery of interblock information is used

In this paper, Yate's missing plot technique is used to derive the formula for substitution in a missing plot in a general incomplete block design, where blocks are assumed to be independent normal. The use of penalized normal equations, using BLUPS, makes this task simpler.     

Graphical methods for comparing confounding in two or more designs

In many circumstances it is necessary to design an experiment with partial confounding of parameter estimates. In this situation, one would like to have tools to assess and compare candidate designs graphically. In this paper we discuss two graphical representations of design properties, and illustrate their application with two examples.     

Optimum chemical balance weighing designs for estimating the total weight

This deals with chemical balance weighing designs which attain a lower bound for the variance of the estimated total weight, The results extend those of Chacko Dey (1978).
