基于DSP与LabVIEW仿生运动机理模型在线切换、离散化系统

仿生运动机理模型在实际的应用过程中,必须针对特定的应用场合和不同的硬件系统选择不同的控制模型和最优参数,使实际效果达到最佳。文章提出了一种基于DSP与LabVIEW,对仿生运动机理模型进行实时在线离散化的方法。该方法实现了控制模型的在线切换、参数的实时修正、模型的在线离散化、LabVIEW和DSP的实时通信。实验结果表明,该系统实时性好、运行可靠。     

The Competitive Impact of Targeted Television Advertisements Using DVR Technology

Digital video recorders (DVRs) are an emerging technology that is fundamentally changing the competitive landscape in industries that advertise on television. Perhaps the most familiar impact of DVR technology is that it enables consumers to avoid advertisements (ads) by fast forwarding through them. However, this “zipping” of ads is only one aspect of the impact of DVR technology. DVRs also collect a wealth of information at the consumer level that can be used by firms to target their ads more effectively. We examine how this targeting capability moderates the impact of ad avoidance in a competitive setting. Insights are provided on how best to manage this emerging technology in terms of the key managerial decisions of product pricing and advertising efforts, as well as its impact on profits in a competitive (duopoly) marketplace.     

Leadership in the digital era: A review of who,what, when,where, and why

Leadership as a social influence process has always involved a complex set of phenomena that demands an interdisciplinary lens. Leadership scholarship has now entered into a digital era. In a digital era, the overall phenomenon is changing, as are the tools through which we study it, demanding a new “lens” through which we view leadership. Yet, this raises the question, to what extent is leadership different in a digital era? In acknowledgement of this trend, a special issue was commissioned at The Leadership Quarterly that sought to stimulate the imagination of leadership scholars and practitioners. In the current work, we begin with a brief review of who, what, when, where and why of digital leadership. We cover leadership in informal contexts (e.g., social media), generalization from face-to-face to virtual contexts, computational modeling, the leveraging of technology (e.g., machine learning; Big Data), as well methodological how-to guides. We then plot a path forward for leadership scholars in the dawn of the digital era.     

数字经济的统计界定和产业分类研究

当前,数字经济已经成为引领科技革命和产业变革的核心力量,然而国内外尚无统一的数字经济定义和产业分类标准,亟需明确数字经济统计界定,统一产业分类标准,为进一步研究分析提供支撑。首先,本文在系统梳理数字经济狭义和广义定义基础上对数字经济进行了广义界定。其次,将其生产活动归纳为核心活动和应用活动两部分。最后,进一步构建中国数字经济产业分类体系,将数字经济核心活动识别为数字设备制造业、数字产品贸易业、数字技术服务业和数字驱动产业4个大类、19个中类,将数字经济应用活动识别为电子商务产业、数字内容产业、数字金融产业、数字政府产业和 其他数字产业5个大类、24个中类,共计9个大类、43个中类。本文研究成果有望为完善中国数字经济产业分类标准、制定产业政策和定量测算产业规模提供参考。

数码时代建立“数码创意摄影”新艺术门类的意义

在数码图像处理技术高速发展和普及的时代,数码像片的后期处理和二次创作变得相对简单和容易。因此,在摄影界引发了如何限制数码艺术创意摄影作品后期处理方法和处理程度的思考。针对此类问题,本文通过重新定义和认识数码摄影时代的像片及图片概念,在数码摄影、数码像片与数码艺术创意图片关系的基础上,提出了建立数码创意摄影或者数码摄影画新艺术门类的观点,对解决当前数码摄影发展过程中面临的各种困惑具有重要意义。

Let’s be careful out there … : how digital rights advocates educate citizens in the digital age

From the early days of the printed press, citizens have challenged and modified the information environment as constructed by governments and media organizations. In the digital era, this struggle is manifested in the work of civil-society organizations calling to expand the boundaries of digital rights such as access to the internet, freedom of speech, and the right to privacy. Alongside their traditional activity of confronting governments and internet organizations, these bodies have also engaged in educating citizens about their rights. In order to shed light on such educational efforts, I examine the activities of four civil-society organizations operating in three countries (Germany, Israel, and the U.S.) by conducting a content analysis of their websites between 2013 and 2015. The results suggest that the organizations’ interactions with the public are guided by three main principles: (1) cultural informational framing: delivering accurate technological and political information, which is framed so as to resonate with the cultural premises and everyday lives of the target audiences; (2) personal activism: propelling citizens toward participation, primarily through political clicktivism and by providing them with technological guidance and tools for digital self-protection; and (3) branding digital rights activism: fostering a unique image for a particular organization’s digital rights activism, mostly through selling merchandise to citizens. Using these strategies, the organizations aim to construct the social–political–cultural identity of a generation who are knowledgeable, politically active, and aware of their rights in the digital age. The characteristics of this identity are discussed in the conclusion.
