Drivers of information technology choice by individuals     

《International Journal of Information Management》2021

Technology acceptance has spawned considerable research in technology adoption, technology use, and technology switching. However, technology choice—i.e., an individual’s selection of a technology from a set of technologies that support similar tasks—has received limited attention in information systems research. This research was aimed at identifying the drivers of technology choice through a series of activities in two universities, in which students chose an information technology tool from various alternatives to complete the given tasks. A thematic analysis was conducted on the reasons for technology choice reported by 249 students, which yielded 18 technology, user, and environmental drivers that influenced individuals’ technology choice. This study provides insights into the drivers generally applicable for technology choice and drivers applicable in specific contexts. Implications for research and practice are discussed.  相似文献

From objects to subjects: Repositioning teachers as policy actors doing policy work     

《Teaching and Teacher Education》2018

Within policy discourses, teachers are positioned as objects of reform who enact policies under rational systems of observation and accountability and are, therefore, situated as de-professionalized actors lacking expert knowledge. This research project asks relatively straight-forward questions: If practicing teachers were given a voice in political debates over urban education policy and reform, what would they say? What macro-level policy problems would they identify as being important? Findings indicate the primary policy problems include Systemic Inequity and Bad Policy. The primary policy solutions include, Schools as a Community Resource; Shared Decision-Making; Contextual Goals; and Time, Space and Resources.  相似文献

政策不确定性与企业粗放型创新:激励效应与选择效应     

甄丽明  罗党论 《科技管理研究》2019,39(14)

创新驱动政策下,地方政府为“创新”而竞争,企业创新呈粗放式模式,投入力度虽不断增强,但专利成果却量多质低。本文研究发现：(1)受新上任政府为“创新”而竞争的政策激励,政策不确定性对企业粗放型创新投入具有明显的促进作用。(2)政策不确定性对粗放式创新质量的影响存在着选择效应,面临政治冲击时,仅“功利性”的策略性创新企业专利申请数量短期内急剧增加,而以提升创新能力为目的的实质性创新专利数量并未显著增加。(3)在以专利数量等为政府资源分配的重要参考指标驱动下,政府补贴这一政策工具在政策不确定性与粗放型创新之间发挥了传导作用。本文结论意味着专利数据考核指标,政府补贴等“非市场”因素增强了企业粗放型创新行为,但并不利于创新质量的提高。  相似文献   

Leveraging Sunken Investments in Communications Infrastructure: A Policy Perspective From the United States     

Anthony G. Wilhelm 《The Information Society》2003,19(4):279-286

Bridging the digital divide between information and technology haves and have-nots has waned from the top of the national policy agenda in the United States during a time in which the sunken investments of the 1990s need to be leveraged. A national information network now exists yet this infrastructure--largely hardware--needs to be continually modernized and parlayed with commitments to building human capacity, developing relevant content, and scaling socially beneficial technology applications, such as telemedicine, in order to optimize these initial multi-billion-dollar outlays. This article makes the case that sidestepping public-private initiatives aimed at accelerating digital opportunity is imprudent, given the mounting empirical evidence highlighting the payoffs of information and communications technologies, when properly integrated and applied, especially in enhancing the life chances of underserved Americans. Policy next steps should advance the goals of expanding universal service initiatives, including hastening broadband deployment to homes and learning institutions, and deepening programs which leverage the utility of the existing infrastructure, such as expanding human-capital development, producing relevant content, and innovating socially beneficial technology applications.  相似文献   

The social strategy cone: Towards a framework for evaluating social media strategies     

《International Journal of Information Management》2016,36(1):1-8

Social media is growing rapidly. Providing both risks and opportunities for organizations as it does. The social strategy cone is developed for evaluating social media strategies. This framework comprises of seven key elements of social media strategies as based on a systematic literature review and case studies. The results of 21 interviews have contributed to the construction of the social media strategy cone for analyzing social media strategies. Three levels of maturity of social media strategy are proposed: initiation, diffusion and maturity. Initiation includes the key elements: ‘target audience’ and ‘channel choice’ while all case organizations studied payed attention to these elements. Diffusion includes the elements: ‘goals’, ‘resources’ and ‘policies’. Maturity adds the elements of ‘monitoring’ and ‘content activities’. Only 3 of the 9 organizations studied are in this phase of maturity. Although, theory suggests the importance of the element of ‘monitoring’ our research shows the need for more attention in practice.  相似文献
