高职教育综合实验教学的研究与探讨

高等职业教育的目标是培养应用型、技能型人才。综合实验能激发学生的学习兴趣,调动学生的积极性,有助于培养学生的动手能力和独立工作能力,确实是一条实验教学改革的好路子。     

全球化进程中大学生理想信念教育探析

全球化的深入发展,极大地改变了人类的生产方式、消费方式、交换方式及其思想行为方式,也使我国的大学生理想信念教育不断面临挑战。由于多元文化的传播及非主流意识形态的影响,大学生政治观念逐渐淡化,主流价值观念受到冲击,理想信念弱化或迁移。因此,应进一步加强马克思主义理论和社会主义核心价值观教育,不断提升主流意识形态影响力;引导大学生准确把握我国的国际定位,增强道路、理论、制度和文化自信;培养大学生国际政治素养。     

Classifying Undecided Voters in Pre-Election Polls

The treatment of "don't know", "no opinion," or other nsonsubstantiveresponses is a problem in many consumer research surveys. Thispaper looks at the problem in the context of 1980 presidentialelection opinion polls. During the campaign, a relatively largeproportion of those interviewed said that they were undecidedas to whom they planned to vote for. Discriminant analysis isused to allocate undecided voters to candidates. The methodis validated by a postelection follow-up survey.     

UPSTREAM VOLATILITY IN THE SUPPLY CHAIN: THE MACHINE TOOL INDUSTRY AS A CASE STUDY

Cyclicality is a well‐known and accepted fact of life in market‐driven economies. Less well known or understood, however, is the phenomenon of amplification as one looks “upstream” in the industrial supply chain. We examine the amplification phenomenon and its implications through the lens of one upstream industry that is notorious for the intensity of the business cycles it faces: the machine tool industry. Amplification of demand volatility in capital equipment supply chains, e. g., machine tools, is particularly large relative to that seen in distribution and component parts supply chains. We present a system dynamics simulation model to capture demand volatility amplification in capital supply chains. We explore the lead‐time, inventory, production, productivity, and staffing implications of these dynamic forces. Several results stand out. First, volatility hurts productivity and lowers average worker experience. Second, even though machine tool builders can do little to reduce the volatility in their order streams through choice of forecast rule, a smoother forecasting policy will lead companies to retain more of their skilled work force. This retention of skilled employees is often cited as one of the advantages that European and Japanese companies have had relative to their U. S. competitors. Our results suggest some insights for supply chain design and management: downstream customers can do a great deal to reduce the volatility for upstream suppliers through their choice of order forecast rule. In particular, companies that use smoother forecasting policies tend to impose less of their own volatility upon their supply base and may consequently enjoy system‐wide cost reduction.     

THE ROLE OF CONSTITUENT TRUST IN CONGRESSIONAL ELECTIONS

The purpose of this inquiry is to introduce a new variable intothe study of congressional elections—constituent trust.Constituent trust is defined as the level of confidence thatconstituents have in their elected representative. This analysissuggests a strategy for measuring constituent trust and developsa model that relates constituent trust directly and indirectlyto electoral support. By pooling cross-sectional data drawnfrom the University of Michigan's American National ElectionStudies (1978–84), I demonstrate that when constituenttrust is salient in voter cognitions, it has a significant directinfluence on electoral support and is a better predictor ofelectoral support than the incumbent's party identification.In addition to its direct effects, I show that constituent trustindirectly influences electoral support because of its causalrelationship to incumbent popularity.     

IT人员业务能力与技术能力的互补性对企业竞争优势的影响

以资源基础观为理论指导,研究IT人员的技术能力与业务能力以及二者的协同效应对企业竞争优势的影响。在已有研究成果的基础上,构建了企业IT人员能力及其互补性与企业经营绩效关联的概念模型,通过对国内300家大中型企业的问卷调查和统计检验,验证企业IT人员的技术能力和业务能力与企业绩效都有着显著的正相关关系,而且这2种能力之间也存在较强的互补性。研究结论显示,技术能力是IT部门人员区别于其他部门的根本,业务能力使IT人员能够更好地理解企业业务,进而充分发挥IT系统的战略作用,产生的协同效应能够进一步提升企业的经营绩效。     

Under New Orders: The Redefinition of Social Work with Young Offenders

Correspondence to Dr. H. Parker, Department of Sociology and Social Work Studies, University of Liverpool, Eleanor Rathbone Building, Myrtle Street, P.O.Box 147, Liverpool L69 3BX Summary This paper reports on the significant changes in policy andpractice presently being implemented by the Probation Serviceand other social work agencies responsible for work with juvenileand young adult offenders. These changes concern Social EnquiryReport writing, the more intensive supervision of young offendersthrough the attachment of day centre type requirements to Supervisionand Probation Orders and the extension of Community ServiceOrders. Illustrating their analysis with data from a nationalsurvey of the Probation Service, the authors argue that thesechanges which have emanated in various forms from central governmenthave had a mixed reception. Whilst on the one hand, this thrustfrom above has been viewed as an unwelcome extension of communitycontrol through social work practice, it has also been seento contain opportunities to provide genuine alternatives tocustody for young offenders. The authors argue that, taken inthe context of recent overall sentencing trends, it is unlikelythat custody rates will decrease significantly, as Courts willtend to use community service and supervision packages to serveother purposes.     

On the Relation between Edge and Vertex Modelling in Shape Analysis

Objects in the plane with no obvious landmarks can be described by either vertex transformation vectors or edge transformation vectors. In this paper we provide the relation between the two transformation vectors. Grenander & Miller (1994 ) use a multivariate normal distribution with a block circulant covariance matrix to model the edge transformation vector. This type of model is also feasible for the vertex transformation vector and in certain cases the free parameters of the two models match up in a simple way. A vertex model and an edge model are applied to a data set of sand particles to explore shape variability.     

Which Children are Registered at Case Conferences?

Correspondence to Terry Fisher, Department of Social Policy and Social Work, University of York, Heslington, York YO1 5DD. Summary A postal questionnaire to social workers was used to describethe characteristics of situations where children were the subjectsof child protection case conferences, to identify factors distinguishingthose registered from those not registered and to describe theaccounts given by social workers of the reasons for registration.The paper reports and analyses this information and raises somebasic issues about the relative importance in registration decisionsof evidence of physical or sexual abuse, characteristics ofthe adults involved, and a child's feelings and emotional state.
