How to improve a technology evaluation model: A data-driven approach

Academic research suggests a number of technology evaluation models. To ensure effective use, models need to be improved in accordance with changing internal and external environments. However, a majority of previous studies focus on model development, while a few emphasize their implementation or improvement. To fill this research gap, this study suggests a systematic approach to examining the validity of technology evaluation models and improving them. We consider three propositions as criteria for improvement: 1) the coherence of the evaluation results with the evaluation purpose, 2) the appropriateness of the evaluation methods, and 3) the concreteness of the evaluation model. Rather than using expert opinions, this study takes a data-driven approach, wherein we analyze actual evaluation results and determine whether the model produces the intended results. A case study of 291 technology evaluation results, all made by the South Korean government in support of technology-based small and medium-sized enterprises, is conducted to verify the suggested approach's applicability. This is one of the few studies to address issues regarding improvements to a technology evaluation model. Its approach can help to develop and continuously improve a valid technology evaluation model, thus leading to more effective practice.     

涉农贷款中新担保措施的合法性及有效性分析

为防范涉农贷款违约风险,部分农村信用联社积极探索,创新出债权文书公证方式、以人身险保险金担保债权等担保方式,以确保债权得到切实维护.这些新担保方式一定程度上增加了农村贷款供给,但存在法律风险.本文着重对这些新措施、新方法的合法性及有效性进行了探讨.     

An Empirical Comparison of the Four Channel Flow Model and Adventure Experience Paradigm

The objective of this study was to conduct empirical comparisons between two models of optimal experience within an on-site whitewater kayaking setting using a modification of the Experience Sampling Method. Four concerns are examined: (1) differences in explanatory power between the four channel flow model and the Adventure Experience Paradigm, (2) convergent validity among measures used to determine conditions within these models, (3) differences among measures of perceived challenge and risk between test times of Class I-V river difficulty, and (4) differences among measures of perceived skill and competence between test times of Class I-V river difficulty. Questionnaires were administered in the Cheat River Canyon in West Virginia to 52 whitewater kayakers at eight sites of various levels of river difficulty. Data were analyzed at the experience level, rather than between subjects, using 409 experience sampling observations. Hypothesis testing, performed with statistical analyses (stepwise regression, correlations, and repeated measures ANOVA), suggested that the explanatory powers of the four channel flow model and Adventure Experience Paradigm were similar and indicated support for convergent and ecological validity of measures used to determine conditions within each of the two models.

Methodological Issues in Negotiation Research: A State-of-the-Art-Review

This study provides insight into the dominant methodological practices that have shaped the field of negotiation over the past four decades and sheds light on possible gaps and trade-offs. We content analyzed 941 peer-reviewed negotiation articles (published between 1965 and 2004) and identified the most important methodological trends over time. The results reveal significant changes in reliability, validity, and triangulation issues. In addition, the rise of multivariate statistics and multiple data sources displays positive evolution towards more sophisticated methodologies. Despite these positive evolutions, we want to encourage current and future researchers to conduct more longitudinal and qualitative research to further advance our knowledge on negotiation.     

会计数据信度与效度的特征性描述——基于会计变量及变量间关系的认识

无形会计数据信度即度量结果的重复性程度,是反映会计数据的客观性指标。效度是判断度量结果即研究对象结果的有效性程度。会计数据的信度与效度的探讨有助于会计信息质量的改善与质量标准的制定,对于进一步展开会计科学的研究也具有一定的意义。本文通过分析会计数据信度与效度的特征性,探讨与验证会计数据信度与效度路径研究方法。     

论比较优势理论的有效性

作为经济学中最重要的理论之一,比较优势理论揭示了贸易模式的产生原因以及贸易利益的来源.然而,自比较优势理论诞生之日起,就受到了来自各方的批评,英有效性一直受到怀疑.本文描述了比较优势理论模型的扩展,并指出在哪些条件下比较优势理论能够成立.通过这样的研究,可以使我们更加充分地认识比较优势理论的有效性问题.     

银行跨境风险参与中的法律问题

境内外银行间跨境风险参与实为跨境债权转让。根据我国现行法律规定,未通知债务人的债权转让仍为有效。银行跨境风险参与规避了我国现行的外债管制政策,影响我国宏观外债数据的真实性、准确性,弱化了外债管理的有效性,亟需填补相关法律漏洞,对其予以有效规范。     

决策有用、有效契约与商誉会计政策的选择

为解决逆向选择和道德风险问题，会计被赋予决策有用性和契约有效性的功能。对决策有用的信息不一定能保证契约的有效，会计的决策有用性与契约有效性之间存在冲突。准则的制定过程实质上是对二者的协调过程。商誉会计政策的选择是决策有用性与契约有效性之间的“恰当平衡”。“优化”商誉会计政策选择的努力，不在于其本身的技术性方面，而在于对会计的经济、社会、制度等环境，以及社会各会计相关集团的信息需求及利益冲突的分析和研究，在于对准则制定机制的不断完善。     

"自然债权"的"维权"--"过了诉讼时效"的债权人在债务人破产时能否实现权利

坚持以人为本的发展观是建设社会主义政治文明,推进依法治国的核心内容,是社会主义法律必须坚持的最高价值和基本精神。本文针对实践中的某一案例,提出了“自然债权”的“维权”问题。从“自然债权”是否真正消失“权利”、我国《破产法》的具体规定、以及法的价值等三个方面进行了系统阐述和分析,提出了“过了诉讼时效”的自然债权人在债务人破产时,也能实现自己实体意义上的债权的观点和建议。
