立体标签自动贴标机结构设计

为了减少在产品包装环节中的人员参与,提高包装环节的自动化程度,研制了一种用于立体标签的自动贴标机。 根据产品贴标的流程,采用Pro/E软件进行三维建模和零部件的优化设计,包括传送机构、标签推进机构和折弯机构。 折弯机构中采用了折弯翻板实现对标签的折弯控制;自动贴标机各机构均采用了独立的电机控制,控制系统采用PLC 技术和变频器调速控制,设计了电动机正反转的控制电路图。通过对机械结构和电气控制系统优化设计,得到了满足设 计要求的自动贴标机机构设计参数,实现了对厚度为0.5 mm纸质标签纸的2次折弯并实现贴标过程。该自动标签机的 使用实现了包装过程的自动化,提高产品的包装效率。

On evaluating interactive statistical program packages

Most statistical computing for data analysis has come to depend upon statistical program packages. In recent years, interactive computing has become widespread both on large time-sharing systems and on mini-computers. This paper identifies ways in which interactive statistical software packages differ from batchoriented software and discusses evaluation considerations pertaining specifically to interactive packages.     

Notes on authors

Social network analysis (SNA), a method which can be used to explore networks in various contexts, has received increasing attention. Drawing on the development of European smoke-free policy, this paper explores how a mixed-method approach to SNA can be utilised to investigate a complex policy network. Textual data from public documents, consultation submissions and websites were extracted, converted and analysed using plagiarism detection software and quantitative network analysis and qualitative data from public documents and 35 interviews were thematically analysed. While the quantitative analysis enabled understanding of the network’s structure and components, the qualitative analysis provided in-depth information about specific actors’ positions, relationships and interactions. The paper establishes that SNA is suited to empirically testing and analysing networks in EU policy-making. It contributes to methodological debates about the antagonism between qualitative and quantitative approaches and demonstrates that qualitative and quantitative network analysis can offer a powerful tool for policy analysis.     

An Evaluation of Simulations in Developmental Disabilities (SIDD): Instructional Software that Provides Practice in Behavioral Assessment and Treatment Decisions

ABSTRACT

Simulations in Developmental Disabilities (SIDD) is a multimedia computer program designed to provide undergraduate psychology students with practice in making assessment and treatment decisions. Eighteen undergraduate psychology students participated in an experiment to test the instructional effectiveness of SIDD. Post-test scores were significantly higher in the experimental group who received training with SIDD than in a control group who did not receive training. The students also rated the software positively. Future strategies to further evaluate the software are discussed.     

Critically assessing digital documents: materiality and the interpretative role of software

As a contribution to the ongoing tradition of critically assessing documents for research, this paper aims to highlight materiality as a key factor in the co-shaping of knowledge derived from digital documents. The paper first builds upon prior debates in document studies with work from the fields of Science and Technology Studies, and Communication Studies, to establish the role of document materiality in the interpretative process. By first establishing digital documents’ material reality as electrical signal, the paper then discusses the interpretative role of software, in both the representation of that signal for human interpretation and the production of the document through software tools. Finally, the paper considers the implications for persistence and access to digital documents posed by their material reality and the private archival contexts in which they often reside.     

聚类分析法在高职院校订单式培养学生综合素质评价中的应用

订单式”人才培养模式的建立为高职教育教学改革注入了新的活力。但是，由高职院校因为缺乏有效的培养过程控制与竞争机制，也出现了影响该模式的良性循环和可持续发展的诸多问题。鉴于此，应尽快完善“订单式”人才培养模式中的过程控制与考核机制，建立一套科学、完备的考核指标体系是当务之急。对于订单式培养学生的综合素质评估结果，可以通过相关聚类分析方法，对订单班学生综合素质评估结果进行科学合理的分类，建立完善订单班学生能进能出、滚动淘汰的动态管理模式，达到订单式培养不仅“定数量”，更注重“定质量”的理想状态。

The Times They are A’changing: Multigenerational Family Simulations

Multigenerational households are increasingly affecting both the individual and family as well as community organizations and social policies. Social work and other family studies students can profit from educational modalities that use adult learning applications through a systems life-course perspective, the whole family aging over time. Family simulation software—addressing multigenerational families, such as two or more adult generations living together—builds on a previous paper (Marriage & Family Review, Feb. 2015). Social class, among other demographic and environmental variables, is emphasized. Agent-based family social network simulation of multigenerational families can facilitate experiential learning. An automatically generated life events report, based on both factual data and specific family characteristics, can be used as a classroom case study for role playing and assessing.     

机械设计与自动化"专业课程设计"的改革与实践

为了培养新世纪新型人才,适应教学改革的需要,针对机械设计与自动化专业的"专业课程设计"一直采用传统模式教学,教学方法、教学手段没有实质性变化,不能满足现在教学发展的要求状况,提出了该项教学改革.利用慧鱼教具尝试了"专业课程设计"新的教学方法,采用机械传动系统设计、硬件控制、编程结合的教学手段,使专业课程设计变成了学生自己的概念设计、创意设计、创新设计的过程,使学生的设计思想以物化的形式表现出来,取得了很好的教学效果.
