Dynamic Monte Carlo simulation of linear SAW polymer chain near a flat surface

INTRODUCTION The conformational property of polymerchains subject to a geometrical constraint is one of themost interesting topics in polymer science (Milner,1991; Malfreyt and Tildesley, 2000; Vacatello,2001). The geometrical constraint can be a solidsurface, a liquid/liquid interface, a vacuum/liquidinterface, etc. So the topic has many applications intechnology such as adsorption onto interface, sta-bilization of colloids and partition equilibrium ingel permeation chromatography…

Judges’ delivery of ground rules to child witnesses in Australian courts

Ground rules directions are given to children in forensic interviews to explain what is expected of them, and to reduce their tendency to acquiesce to erroneous or incomprehensible questions. Ground rules may also be necessary when children provide testimony in court. Drawing on research conducted for the Australian Royal Commission into Institutional Responses to Child Sexual Abuse, the present study examined the use of ground rules directions delivered in court in 52 trials by 24 presiding judges in three jurisdictions to 57 child complainants (aged 7–17.5 years). Eleven categories of rules were identified. The number of words spoken to deliver each rule was counted, and grade-level readability scores were calculated as a proxy for the complexity of the ground rules. When judges asked comprehension or practice questions, the question types were coded. More than one third of the children (35%) received no ground rules directions from the judge; the remaining 65% received directions on an average of 3.5 types of ground rules out of a maximum of 11 types. While comprehension questions were common, practice questions were rare. Comprehension questions were most often presented in a yes/no format that implied the expected response, although this form of question is unlikely to provide an effective assessment of a child's comprehension. Neither the number of rules delivered nor the number of words used was related to children's age. Implications for children's court testimony are discussed.

Managing What We Can Measure: Quantifying the Susceptibility of Automated Scoring Systems to Gaming Behavior

As methods for automated scoring of constructed‐response items become more widely adopted in state assessments, and are used in more consequential operational configurations, it is critical that their susceptibility to gaming behavior be investigated and managed. This article provides a review of research relevant to how construct‐irrelevant response behavior may affect automated constructed‐response scoring, and aims to address a gap in that literature: the need to assess the degree of risk before operational launch. A general framework is proposed for evaluating susceptibility to gaming, and an initial empirical demonstration is presented using the open‐source short‐answer scoring engines from the Automated Student Assessment Prize (ASAP) Challenge.     

长江口深水航道船舶超宽交会通航效率分析

为提高长江口深水航道通过能力,减少由船舶交会宽度限制产生的延误,通过分析船舶超宽交会现状,建立仿真逻辑模型,运用Arena进行离散仿真试验。采集长江口深水航道交通流数据,设置不同的船舶交会宽度限制,对大型船舶进出港过程进行仿真,分析不同交会宽度限制对船舶通航的影响,获得被延误船舶比例、被延误船舶数量和延误时间,进而提出提升通过能力的建议。试验表明,采用Arena进行离散仿真能够量化分析超宽交会对通航效率的影响,可为航道拓宽和交通管理提供科学依据。
