美国《早期学习与教育技术政策简报》对我国学前教育信息化的启示

美国《早期学习与教育技术政策简报》是关于幼年学习者使用技术的政策简报,回应了“α世代”信息化生存问题,解答了“21世纪,儿童获得技术是必要的,但还不够”现实难题。该政策简报中愿景、早期学习者技术使用指导原则和呼吁行动三部分分别从本简报出台的初心、如何指导幼儿恰当使用技术,呼吁社会各界力量协同实现本简报的初心等方面进行阐述。美国《早期学习与教育技术政策简报》对提升我国学前教育信息化水平、提高幼儿园教师信息素养和构建幼儿信息化生态系统,满足我国学前教育利益相关者的“技术促进学习”时代诉求等方面提供有益参考。     

On the Choice of Functional Forms: Summary of a Monte Carlo Experiment

The use of flexible functional forms is a standard practice in applied econometrics. Many flexible forms have been proposed. In this study, we investigate the behavior of three of them—the translog, the symmetric McFadden, and the symmetric generalized Barnett. Based on Monte Carlo experiments, we assess the ability of these forms to test theoretical properties and to measure technological characteristics.     

An Exploratory Analysis of the Value of the Skills of IT Personnel: Their Relationship to IS Infrastructure and Competitive Advantage

Determining and assessing the requisite skills of information technology (IT) personnel have become critical as the value of IT has risen in modern organizations. In addition to technical skills traditionally expected of IT personnel, softer skills like managerial, business, and interpersonal skills have been increasingly cited in previous studies as mandatory for these employees. This paper uses a typology of IT personnel skills—technology management skills, business functional skills, interpersonal skills, and technical skills—and investigates their relationships to two information systems (IS) success variables, IS infrastructure flexibility and the competitive advantage provided by IS. The study investigates these relationships using the perceptions of chief information officers (CIOs) from mostly Fortune 2000 companies. The contributions of this study are: IT personnel skills do affect IS success, technical skills are viewed as the most important skill set in affecting IS infrastructure flexibility and competitive advantage, and modularity is viewed as more valuable to competitive advantage than integration. Several explanations are offered for the lack of positive relationships between the softer IT personnel skills and the dimensions of IS success used in this study.     

Evaluation of Embedded Intelligent Real‐time Systems*

Over the past two decades, questions have surfaced about the effectiveness and contribution of intelligent systems to decision makers in a variety of settings. This paper focuses on the evaluation challenges associated with intelligent real‐time software systems that are embedded in larger host systems. With the proliferation of such systems in operational settings such as aerospace, medical, manufacturing, and transportation systems, increased attention to evaluations of such systems, and to resulting software safety, is warranted. This paper describes one such evaluation and proposes a set of evaluation criteria for embedded intelligent real‐time systems (EIRTS). Implications of the evaluation and the evaluation criteria are discussed.

投资品相对价格、技术冲击与劳动要素投入——基于RBC观点的一个实证研究

本文由实证层面详细地考察了中性的与投资技术冲击对于我国劳动就业的宏观动态影响.基于投资品相对价格的长期趋势特征,我们发现:在长期限制识别条件下,正向的投资(中性)技术冲击对于劳动就业具有明显的促进作用(负向的抑制效应).这意味着,仅考虑单一中性技术冲击的SVAR模型混淆了不同性质的技术冲击对于劳动就业的不同影响.     

The Role of Organizational and Information Technology Antecedents in Reengineering Initiation Behavior*

Business Process Reengineering (BPR) has been a major catalyst of the pervasive organizational change we have witnessed over the past decade. Although one can speculate on the reasons for the popularity of this phenomenon, it is important that we carefully examine its underlying antecedents for initiation, implementation, and ultimately success, if we are to add value to practitioners of this concept. This study empirically examines the importance of facets of the organizational structure, IT knowledge resources and infrastructure, and the IS function in the initiation of BPR. Data from 313 corporations were gathered using a carefully validated survey, and initiators were compared with noninitiators. The results strongly suggest that client-server architectures, the strategic integration of IS, and cross departmental interaction are among the more important factors facilitating initiation and can be important inputs in a BPR decision-making process. The study attempts to build a contingent theory for BPR, and the more sustainable notion of fundamental process change.     

The Social Media Release as a public relations tool: Intentions to use among B2B bloggers

The Social Media Release (SMR) is emerging as a potentially powerful public relations tool in a world of social network media, particularly when targeted at influential bloggers. The research described here studies the factors that influence bloggers to use SMRs, using the Technology Acceptance Model as a theoretical framework, concentrating specifically on their perceptions of usefulness and ease of use.     

A Framework for Examining the Interface between Operations and Information Systems: Implications for Research in the New Millennium*

Even though much research has been published in operations and information systems, both functional areas find their roots in other disciplines. While operations management evolved from operations research in the 1960s, the field of information systems is of more recent vintage and traces its original roots to computer science. Both disciplines now naturally have come closer together as information and process-technology-based changes force manufacturing firms to become more efficient and customer focused. Market and technology-driven e-commerce initiatives that are likely to dominate business strategies in the future cannot be successfully achieved without a successful integration of operations and information systems. In this paper, we present a unifying framework that can be used to better understand the management of the functional interface between operations and information systems. We also categorize and highlight the contributions of the articles that appear in this special research focus issue. Finally, research directions that emerge from our understanding of this interface are outlined in an effort to stimulate further thinking and research that can advance our knowledge of this interface area.
