An Assessment of on-line package customization for sheet size products packaged in paperboard envelopes

This study evaluates the on-line printing of paperboard envelopes as a means of supporting the need to provide customized packaging. Market forces and new business models are contributing to the need for customized packaging and rapid response to orders. Large retailers are demanding unique packaging presentations and global marketing requires localized packaging for different regions of the world. A business environment ofjust-intime delivery and minimal inventory levels demand flexibility to react to unpredictable product mix and volumes. These conditions require customized packaging within short cycle times. The traditional carton printing process using offset lithography does not respond quickly enough to meet these needs. Alternate methods of applying graphics to paperboard envelopes provide the capability to respond to the need for customized packaging quickly. This study evaluates several alternative application methods to test the hypothesis that on-line graphics application can provide high quality graphic presentation for low volume, customized packages at a cost that is competitive with traditional offset carton printing

How May I Impress You? A Content Analysis of Online Impression Management Tactics of YouTube Beauty Vloggers

This research aims at investigating how YouTube beauty vloggers utilize impression management tactics to convey the intended image in an online environment by analyzing their self-presentational behaviors. Two individual coders coded one hundred videos that top trending on YouTube, featuring some single human vloggers who used English as the primary presentation language. Results revealed that first, vloggers had engaged with all four self-presentational behavioral strategies (verbal expressions, nonverbal cues, artifactual displays, and purposive behaviors) in the seemingly amateur videos. Second, a commonly shared feature of top trending vlogs was that they were all designed with abundant and diverting content, indicating that viewers favored the content more than the structure of the vlog. Third, most presenters demonstrated extraverted and likeable personality traits. Fourth, viewers preferred to watch the vlogs with natural props and in simpler environmental settings. Lastly, vloggers chose to use more acquisitive impression management tactics than protective ones in top trending vlogs, and the results showed that viewers also displayed consent to receiving more positive framing

The JPEG2000 still image compression standard

The development of standards (emerging and established) by the International Organization for Standardization (ISO), the International Telecommunications Union (ITU), and the International Electrotechnical Commission (IEC) for audio, image, and video, for both transmission and storage, has led to worldwide activity in developing hardware and software systems and products applicable to a number of diverse disciplines [7], [22], [23], [55], [56], [73]. Although the standards implicitly address the basic encoding operations, there is freedom and flexibility in the actual design and development of devices. This is because only the syntax and semantics of the bit stream for decoding are specified by standards, their main objective being the compatibility and interoperability among the systems (hardware/software) manufactured by different companies. There is, thus, much room for innovation and ingenuity. Since the mid 1980s, members from both the ITU and the ISO have been working together to establish a joint international standard for the compression of grayscale and color still images. This effort has been known as JPEG, the Join

Adherence of Prime-Time Television Advertising Disclosures to the “Clear and Conspicuous Standard: 1990 vs. 2002

In 1990, one-fourth of all national television commercials contained disclosures, yet none of the disclosures adhered to all of the Federal Trade Commission\u27s clear and conspicuous standard (CCS). As a result of marketplace changes and a 2001 Federal Trade Commission and National Advertising Division joint workshop, the authors anticipate an increase in the number of disclosures and greater adherence to the CCS. The authors find a significant increase in disclosure incidence; however, adherence declines or remains unchanged for most individual guidelines. Finally, the authors provide public policy implications and offer suggestions to increase adherence to the CCS

Digital Image Access & Retrieval

The 33th Annual Clinic on Library Applications of Data Processing, held at the University of Illinois at Urbana-Champaign in March of 1996, addressed the theme of "Digital Image Access & Retrieval." The papers from this conference cover a wide range of topics concerning digital imaging technology for visual resource collections. Papers covered three general areas: (1) systems, planning, and implementation; (2) automatic and semi-automatic indexing; and (3) preservation with the bulk of the conference focusing on indexing and retrieval.published or submitted for publicatio

Image coding using wavelet transform and adaptive block truncation coding

This thesis presents a new image coding using wavelet transform and adaptive block truncation coding. Images are first pre-processed by the wavelet transform and then coded by the adaptive block truncation coding. Algorithms for both monochrome and color images are proposed and experimentally studied. The adaptive block truncation coding is also modified to achieve better performance. For coding monochrome images at the bit-rate region between 0.8 to 1.2 bits/pixel, the performance of the new coding is comparable to the ones of subband codings and other image codings using the wavelet transform; however, the new coding offers less computational load. The new coding also gives a good reconstruction of a color image at the bit-rate of 1.0 bit/pixel. The comparison between the new coding and the original adaptive block truncation coding is also given. The discussion on effects of a filter and a number of decomposition levels used for an implementation of the wavelet transform is included in this thesis, as well

Gender Images and Power in Magazine Advertisements: The Consciousness Scale Revisited

This study re-evaluates the Consciousness Scale originally formulated by Pingree et al. in 1976. The element of assumed power was added to the Consciousness Scale, which was then used to evaluate 516 magazine advertisements from 1999 to determine if the Consciousness Scale still accurately evaluates sexism in media. A set of advertisements was culled which had contradictory Consciousness Scale and power ratings. The set was evaluated, revealing common themes, which created difficulty in coding these modern images. The study revealed that while the Consciousness Scale can still provide a valuable tool in evaluating media images, the change in the social dynamic of women as well as minorities and how advertisers portray them must be taken into account. The element of power as well as a more nuanced reading of each level of the Consciousness Scale creates a more modern and complex evaluation of gender images in the media
