There can be intellectual property rights in digital images in the form of copyright. Images are commonly shared online, particularly in social media. When digital images are shared online, this can have implications on the copyright in the images. This article highlights a number of copyright concerns, potential solutions and recommendations for creators and copyright owners of digital images, as well as those using and sharing the images.  相似文献

新《证券法》直接体现了数字经济的内容,主要有:将对客户保密制度升级为投资者个人信息保护制度,明确信息披露的载体包括证券交易场所网站,规定证券登记结算机构可以提供信息服务,在证券交易方面大幅度增加电子化交易的内容,尤其是新增了程序化交易和信息技术系统服务机构,等等。当然新《证券法》在信息技术系统服务机构和程序化交易方面需要进一步细化。而诸如互联网、云计算、大数据等数字技术都是数字经济时代的新型技术,它们虽然没有规定在新《证券法》中,但却对于新《证券法》的实施具有重要意义。未来包括投资性众筹、智能投顾和区块链结算在内的数字经济内容将会在新《证券法》的进一步修改中得到更多体现。  相似文献

As membership levels decline, parties are developing new forms of linkage with supporters, many of which rely on Internet technologies. To date, the discussion of these new modes of affiliation has been largely theoretical in nature, with little, if any, systematic empirical analysis undertaken on their appeal and impact on formal membership. This article seeks to fill this gap by examining the presence of three new types of digital affiliation—audience, friends, and digital activists—among the French electorate using original survey data from the 2012 Presidential election. Our findings are important in showing that while the new methods of affiliation are increasing parties’ reach into society, they are not necessarily widening parties’ socioeconomic support base. Furthermore, digital activism is mostly a supplementary channel for members’ input although there are a smaller group of people engaging in these activities that avoid formal membership ties. Such results suggest that digital methods of affiliation might offer an important new resource to parties during campaigns.  相似文献

Research dealing with the nexus of collective action, political participation, and digital media confronts three challenges: conceptualizing digital media as an influence on human behavior, finding common ground among new theories, and connecting together individual-level models with structural-level theories. This article addresses these challenges as a theoretical undertaking. It argues that the digital media environment should be understood as a change in the context for action rather than as an individual-level variable, and that this changed context is relevant to behavior because it expands opportunities for action. This expansion involves a range of structural possibilities for viable collective action that entail at least three paths: organizational prompts, social prompts, and self-initiation. There are theoretical reasons to expect that individual-level attributes including age, education, ideology, and personality may differentially affect people’s susceptibility to these prompts. Future research may profit from refinements to behavioral models that account for possible differences across structurally different prompts for action.  相似文献

During a bloodstain pattern analysis, one of the essential tasks is to distinguish between different kinds of applied forces as well as to estimate their level of intensity. In this study, high‐speed digital imaging has been used to analyze the formation of cast‐off patterns generated by a simulated backswing with a blood‐bearing object. For this purpose, 0.5 mL blood was applied evenly over the last 5 cm of a blade simulant. Bloodstains were created through the controlled acceleration of a backswing at different speed levels between 1.1 m/sec and 3.8 m/sec. The flight dynamics of blood droplets were captured with an Olympus® i‐Speed 3 high‐speed digital camera with a Nikon® AF Nikkor 50 mm f/1.8 D lens and analyzed using the Olympus i‐Speed 3 Viewer software. The video analysis showed that, during the backswing, blood droplets would move toward the lower end of the knifepoint and would be tangentially thrown off. These droplets impacted on the horizontal surface according to the arc of the swing. An increase in velocity led to longer cast‐off patterns with distinct morphological characteristics. Under laboratory conditions, bloodstain pattern analysis allows certain conclusions about the intensity of a backswing and provides instructions on the position of the offender. However, due to the number of unknown variables at a crime scene, such interpretation of cast‐off patterns is extremely limited and should be performed with extreme caution.  相似文献

Already leading the world in the development of consumer electronics, South Korea and Japan have been leading innovators in the creation of digital content economies. Both governments recognized both the commercial potential and the employment possibilities associated with the digital content industry. The sector, however, did not fit easily with existing industrial and technological models of economic development, particularly due to the small size of digital firms, the youth culture orientation of most products and services, and the antiestablishment ethos of the creative industries generally. In Japan, digital content firms created a robust domestic market but struggled to get international market share. Government policy, therefore, has focused on building international interest in digital products. Although South Korea has enjoyed considerable success through their K‐pop cultural exports, it has really capitalized on the country's highly successful online gaming industry. South Korean policy initiatives emphasize public promotion of Korean digital content with sizeable investments in creator and incubator spaces for start‐up firms. Together with initiatives in Singapore, Malaysia, Hong Kong, and Taiwan, the Japanese and South Korean efforts demonstrate how Asian countries have sought to integrate the digital content sector into their national innovation strategies and to jump‐start a promising and potentially valuable economic sector.  相似文献

The Microsoft Windows operating system continues to dominate the desktop computing market. With such high levels of usage comes an inferred likelihood of digital forensic practitioners encountering this platform during their investigations. As part of any forensic examination of a digital device, operating system artifacts, which support the identification and understanding of how a user has behaved on their system provide a potential source of evidence. Now, following Microsoft's April 2018 build 1803 release with its incorporated “Timeline” feature, the potential for identifying and tracking user activity has increased. This work provides a timely examination of the Windows 10 Timeline feature demonstrating the ability to recover activity‐based content from within its stored database log files. Examination results and underpinning experimental methodologies are offered, demonstrating the ability to recover activity tile and process information in conjunction with the Windows Timeline. Further, an SQL query has been provided to support the interpretation of data stored within the ActivitiesCache.db .  相似文献

Event reconstruction is an important phase in digital forensic investigation, which determines what happened during the incident. The digital investigator uses the findings of this phase to prepare reports for the court. Since the results must be reproducible and verifiable, it is necessary that the event reconstruction methods be rigorous and strict. In order to fulfill the legal requirements, this study proposes an event reconstruction framework which is based on the formal mathematical methods. In particular, it uses the temporal logic model checking that is an automatic verification technique. The idea is that the system under investigation is modeled as a transition system. Then the digital forensic property is specified using the modal μ-calculus. Finally, a model checking algorithm verifies whether the transition system meets the property. In order to demonstrate the proposed formal event reconstruction framework, an abstract model of the FAT file system is presented and some digital forensic properties are formulated. A big problem in model checking is the so-called state space explosion. This study addresses this problem and suggests some solutions to it. Finally, the proposed framework is applied to a case study to demonstrate how some hypotheses can be proved or refuted.  相似文献
