Corporate Value Assessment based on the EVA Model and Relative Valuation

As a risk-averse commodity, gold has seen new development opportunities in retail due to factors (e.g., geopolitical risks and conflicts, economic uncertainties, and inflation). Consequently, more and more investors are focusing on the gold retail industry. Evaluating the value of gold retail enterprises using scientific and effective methods is of great significance to both managers and investors. Therefore, this paper uses Chow Tai Seng, a Chinese gold retail enterprise, as a case study. Based on the company's development characteristics, we employ the EVA absolute valuation method and relative valuation methods including P/E, P/B and P/S ratios for valuation. The study finds that although its EVA values show a general downward trend from 2019 to 2023, they remain positive, indicating that the company's overall development is still on track. The development of enterprise valuation theory has gone through the MM (Modigliani-Miller) theory, Free Cash Flow Valuation Model, and the Capital Asset Pricing Model, among others. These theoretical models have gradually improved, and the theoretical system is continuously evolving. By summarizing and reviewing valuation theories and methods, this paper employs the DDM for valuation and the P/E ratio method under relative valuation based on the company's development characteristics. Combining these two valuation methods with the company's actual financial data and relevant value theories, the company can attract investors and address undervaluation by increasing its exposure through modern multimedia channels and enhancing data transparency.

Abstract 818: Fighting prostate cancer with a multimedia approach

Abstract Introduction: Black men have the highest prostate cancer (CaP) mortality rates. The reason for this disparity is multifaceted, including the barriers that they face at the individual, provider, and health system levels. To address these challenges the iCCaRE for Black Men Consortium uses a multi-level approach to disseminating CaP information. This approach is rooted in research which shows that Black men prefer to receive information through multi-media channels tailored to their needs. In addition, studies have reported that CaP survivors were viewed as credible sources of information. This presentation reports on how iCCaRE Consortium is bridging the digital divide in minoritized communities to disseminate CaP information in a way that is meaningful to the community. Methodology: iCCaRE uses a multimedia method to reach Black men. This includes twitter post, Facebook, YouTube, ecancer and community lunch and learns. In addition to social media, we have partnered with LitTV Network, a locally owned digital TV platform, on which we have iCCaRE TV. On Lit TV network we have the ability to reach 11,000 homes in our catchment area. Furthermore, the consortium has produced informational flyers that are disseminated at outreach events and at the American Legion Post 197. On the twitter page the consortium post: (1) 2 scientific publications per day authored by members of the consortium, (2) 2 weekly “Did You Know” facts about prostate cancer with sources attached, (3) 2 weekly url post sharing a link to a video from the iCCaRE consortium YouTube page and (4) clips of CaP survivors sharing their experiences. On the YouTube page we currently have: videos series of a CaP survivor who is also a physician scientist, interview series with MPIs and members of the consortium, CaP survivor series including a barbershop interview with a survivor. Results: The iCCaRE Consortium multimedia efforts have a global reach, in less than a year we have gained 102 twitter followers. On average the twitter page receives 8,700 impressions during the CaP awareness month in September the twitter page garnered over 14,000 impressions. Our videos on the ecancer platform have a combined global view of 341 representing countries such as the United States, Nigeria, Cameroon, United Kingdom, Macedonia, and Mexico. The American Legion Post 197 in North Jacksonville has served a cumulative of 229 people through outreach and educational event called lunch and learns. Our YouTube channel has had almost 100 views in its first month of being active. Conclusion: Using a multi-level approach to reduce the burden of CaP for Black men is vitally important; without such efforts the disparate thread in mortality will continue to persist. Meeting Black men through the mediums they use for gathering health information removes barriers, increases access and will aid in the fight against CaP for Black Men.

Managing Reputation in a Crisis: How Communication Channels Impact Trust

Purpose: The aim of this study was to explore on how to manage a reputation in a crisis and how communication channels impact trust. Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low-cost technique as compared to field research, as the main cost is involved in executive's time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library. Findings: The findings revealed that there exists a contextual and methodological gap relating to managing reputation in a crisis and how communication channels impact trust. Preliminary empirical review revealed that the effectiveness of using multimedia channels, such as video and infographics, in crisis communication and had enormous impact on trust. Multimedia formats were found to enhance comprehension and trust in crisis messages. Recommendations: Situational Crisis Communication Theory (SCCT), Communication Accommodation Theory (CAT) and Information-Motivation-Behavioral Skills Model (IMB Model) may be used to anchor future studies on how to manage a reputation in a crisis using communication channels to impact trust. The integration of multimedia elements, such as videos, infographics, and visual aids, into crisis communication strategies should be considered. Visual content enhances stakeholder comprehension and fosters trust in the information conveyed. Internal communication channels should not be underestimated, particularly in maintaining trust among employees. In times of crisis, employees can serve as powerful advocates or detractors based on their perception of the organization's actions and transparency.

Workers' Perception Heat Stress: Results from a Pilot Study Conducted in Italy during the COVID-19 Pandemic in 2020.

Many workers are exposed to the effects of heat and often to extreme temperatures. Heat stress has been further aggravated during the COVID-19 pandemic by the use of personal protective equipment to prevent SARS-CoV-2 infection. However, workers’ risk perception of heat stress is often low, with negative effects on their health and productivity. The study aims to identify workers’ needs and gaps in knowledge, suggesting the adaptation of measures that best comply with the needs of both workers and employers. A cross-sectional online questionnaire survey was conducted in Italy in the hottest months of 2020 (June–October) through different multimedia channels. The data collected were analyzed using descriptive statistics; analytical tests and analysis of variance were used to evaluate differences between groups of workers. In total, 345 questionnaires were collected and analyzed. The whole sample of respondents declared that heat is an important contributor to productivity loss and 83% of workers did not receive heat warnings from their employer. In this context, the internet is considered as the main source of information about heat-related illness in the workplace. Results highlight the need to increase workers’ perception of heat stress in the workplace to safeguard their health and productivity. About two-thirds of the sample stated that working in the sun without access to shaded areas, working indoors without adequate ventilation, and nearby fire, steam, and hot surfaces, represent the main injuries’ risk factors.

The development of information and communication technologies and the digitalization of the media space create new opportunities for the popularization of scientific knowledge. There is an objective need to study popular science journalism as an activity that develops a multimedia network format and various media content distribution channels. The work is aimed at analyzing the features of the development of popular science journalism on the Internet in the context of cross-media. The study employed general scientific methods (analysis and synthesis), a method of studying documents with elements of content analysis, a comparative method that includes a comparison of different types of content, as well as data from social network and messenger analytics services. The authors studied media channels and ways to promote media content, its ideological, thematic, and structural characteristics, the features of its transformation on high citation index ratings scientific-oriented platforms Nplus1.ru and Naked-science.ru. As a result of the conducted research, it was discovered that the audience involved in the studied online media is carried out through a differentiated cross-media presence, the use of rewriting, and reposting processes. Particular attention was focused on the comparative analysis of the media content of official websites, accounts in the social network VKontakte, and Telegram messenger.

Film and television industry cloud exhibition design based on 3D imaging and virtual reality

The three-dimensional virtual scene can provide users with a visual three-dimensional virtual environment, with various multimedia channels such as sound, video, force feedback equipment, etc., to bring users a completely immersive interactive experience. This paper introduces 3D imaging and virtual reality technology in the film and television industry cloud exhibition, and develops a virtual display platform. First of all, this paper divides the registration into two processes: camera calibration and joint calibration of the camera and laser scanner based on the calibration results. Camera calibration can determine the plane model of the calibration board in the camera coordinate system, and the joint calibration uses the RANSAC algorithm to extract the point cloud of the plane model of the calibration board, and then optimizes the distance between the points in the plane model point cloud and the corresponding plane in the camera coordinate system Find the optimal transformation between the two sets of data, and then calculate the registration relationship between the point cloud and the image. Secondly, this article conducts a demand analysis of the film and television industry cloud exhibition platform based on virtual reality technology, including the business goals set by the platform, platform system analysis, overall design, and system operating environment and configuration requirements. This model provides a feasible solution for the visual interaction of the cloud exhibition design of the film and television industry.

IASSIST

The iASSIST is an iPhone-based assistive sensor solution for independent and safe travel for people who are blind or visually impaired, or those who simply face challenges in navigating an unfamiliar indoor environment. The solution integrates information of Bluetooth beacons, data connectivity, visual models, and user preferences. Hybrid models of interiors are created in a modeling stage with these multimodal data, collected, and mapped to the floor plan as the modeler walks through the building. Client-server architecture allows scaling to large areas by lazy-loading models according to beacon signals and/or adjacent region proximity. During the navigation stage, a user with the navigation app is localized within the floor plan, using visual, connectivity, and user preference data, along an optimal route to their destination. User interfaces for both modeling and navigation use multimedia channels, including visual, audio, and haptic feedback for targeted users. The design of human subject test experiments is also described, in addition to some preliminary experimental results.

Development of a whiteboard video for managing trauma patients outside a tertiary trauma centre.

ABSTRACTThis article describes the process of developing an educational whiteboard video for community trauma management and transport. Whiteboard videos have become widely used as educational resources for various medical subject matters. These short videos package information concisely through real-time illustration with an accompanying narration. Based on a needs assessment we created a free open access educational resource for community trauma management and transport. A group of interdisciplinary trauma providers partnered in content/script development, video design and dissemination. A third-party production company oversaw video animation and voice-over. The video was disseminated widely through stakeholders and various multimedia channels. We surveyed a sample of our intended audience and the majority of respondents perceived the video to be an effective educational resource. Although cost may represent a potential barrier for producing whiteboard videos, there appears to be a role in creating educational content using this multimedia format.

Lower Bound on Bandwidth and Channel Assignment Algorithm for Multimedia Communication in Cellular Networks

Channel assignment problem in hexagonal cellular networks for multimedia services in a 2-band buffering environment is addressed here. We consider the simplest case of only two types of multimedia services, each having different bandwidths. We first derive lower bounds under different conditions on the minimum bandwidth requirement for assigning multimedia channels to a seven-node subgraph of the hexagonal cellular network by using a novel technique where assignment of different types of signals to support multimedia services are interleaved in the assignment process for the minimum bandwidth. We next propose a multimedia channel assignment algorithm to satisfy the non-homogeneous demands at each node of the network. To evaluate the performance of our proposed algorithm, we present new benchmark instances for multimedia communication. Our proposed algorithm, when run on different benchmark instances, comes up with assignments which require a minimum of 7 percent and a maximum of 40 percent more bandwidth than their corresponding lower bounds. The execution time for all the modified Philadelphia benchmark instances defined on a 21-node network is always within 265 milliseconds on an HPxw8400 workstation, while that for the modified benchmark instances defined on a 55-node network is within 733 milliseconds.

Evaluating the role of digital intervention design in treatment outcomes and adherence to eTherapy programs for eating disorders: A systematic review and meta-analysis.

Despite the existence of reviews which document the effectiveness of online therapies, there is little consensus regarding the exact components of online treatment delivery that are most effective in maintaining user engagement and reducing eating disorder (ED) symptomology. The current review and meta-analysis aimed to determine which components of web-based, ED self-help interventions are associated with lower attrition and improved therapeutic outcome. A systematic search of electronic databases (PsycINFO, Medline, Web of Science, Scopus) was conducted for published studies of web-based interventions for EDs and a meta-analysis of the final included studies was performed. Each intervention was coded across four dimensions, including the multimedia channels employed (e.g., text, audio, videos), degree of user interactivity (e.g., online self-monitoring, skills exercises), level of automated feedback (e.g., reminders, personalized feedback), and technological device through which the program was accessed (e.g., smartphone, computer). A final 23 papers were included. The results of meta-regressions indicated that higher scores on the multimedia subscale were associated with greater ED symptom improvement in treatment groups. Conversely, a higher degree of feedback in the treatment group was associated with a group difference in ED psychopathology favoring the control group. Other intervention components were not associated with treatment outcome or dropout. The results are discussed in relation to limitations of the scale used to quantify digital intervention features, as well as the limited diversity and technological sophistication of available ED digital interventions. Such findings indicate the importance of understanding the digital components, which differentiate online therapeutic programs.

MovRec combines these features by using the CombMNZ model to rank and recommend movies.FindingsThe performance evaluation of MovRec clearly demonstrates its effectiveness and its recommended movies are highly regarded by its users.Originality/valueUnlike Amazon and other online movie recommendation systems, such as Common Sense Media, Internet Movie Database and TasteKid, MovRec is unique, as to the best of the authors’ knowledge, MovRec is the first personalized children movie recommender.

Citizen science and early detection of invasive species: phenology of first occurrences of Halyomorpha halys in Southern Europe

Early detection of invasive alien species and the ability to track their spread are critical for undertaking appropriate management decisions. Citizen science surveys are potentially valuable tools for quickly obtaining information on biodiversity and species distributions. The Asian brown marmorated stink bug, Halyomorpha halys, is an invasive pest of agricultural crops and a dwelling nuisance. Halyomorpha halys was first recorded in Italy in 2012 in Emilia Romagna, one of the most important fruit producing regions of Europe. To rapidly obtain data on its distribution in the newly invaded area, a survey that combined citizen science and active search was set up using multimedia channels. Data concerning when, where and how the bugs were spotted were collected, together with photographs and specimens. The survey detected established breeding populations in different areas of Northern Italy and Southern Switzerland, indicating a potentially high risk for crop damage that extends beyond the territories of first detection. Furthermore, new data on H. halys phenology, host plants, voltinism and behaviour were obtained. The importance of citizen science in early detection of introduced pest species is highlighted. This paper also provides a picture-based key to recognize H. halys from similar pentatomids in the world.

Multimedia for Learning in Economy and Cybernetics

The use of many multimedia channels in order to bring information to target groups is not something new. What is new is related to how these channels are exploited by mixing techniques and technologies. We realized an online questionnaire to identify the multimedia techniques/tools that have impact on user’s satisfaction. We used comparative statistical analyses (Levene’s test) to observe if there are any significant differences between multimedia users and non-multimedia users. We identified that the preferred techniques are: the presence of a narrator, the existence of some suggestive images, slides and demos. These are only some factors that we identified. We studied also the influence of features as: access to, scenario type, interactivity, flexibility, additional options and effects and time dependency. We determined that the existence of useful links is an important factor for overall satisfaction of the user with multimedia materials.

Encrypting video and image streams using OpenCL code on- demand


 
 
 The amount of multimedia information transmitted through the web is very high and increasing. Generally, this kind of data is not correctly protected, since users do not appreciate the amount of information that images and videos may contain. In this work, we present architecture for managing safely multimedia transmission channels. The idea is to encrypt or encode images and videos in an efficient and dynamic way. At the same time, these media could be enhanced applying a real-time image process. The main novelty of the proposal is the application of on-demand parallel code written in OpenCL. The algorithms and data structure are known by the parties only at communication time, what we suppose increases the robustness against possible attacks. We conducted a complete description of the proposal and several performance tests with different known algorithms.
 
 

Relative Communication Power of Selected Advertising Media

Advertising is a major communication tool employed to impart information, develop attitude and induce action. DAGMAR communication spectrum theory specifies that in order to attain its objectives, an advertisement must create awareness, ensure message comprehension and conviction; and stir purchase action. Achieving marketing and communication objectives have become more daunting with the present upsurge in media cost and fragmentation as consumers are exposed to ever-increasing number of media daily. Thus, attaining communication effectiveness requires pragmatic management of multimedia channels. Unarguably therefore, exploring different ways in understanding the potentialities of the many media types available is imperative. Hence, the present study sought to explore the relative strengths of some selected media such as television, radio, transit and packaging in moving prospects through the entire levels of the communication spectrum. The study was purely descriptive. Closed-ended structured questionnaires served as study instrument administered on 350 randomly selected respondents from Surulere local government area of Lagos state, Nigeria. Using SPSS (version 19) the generated data was rightly analyzed through the aid of pertinent statistical tools. Results show television to have relatively higher strengths than the other media under study in all four elements of the communication spectrum. Radio and transit have their best strengths in awareness creation while packaging’s strength lies best in moving prospects from message comprehension and conviction to stirring them to purchase action. A combination of television, radio and transit is recommended as the right media mix to achieve awareness creation. Also, a cocktail of television, packaging and radio will provide the best media mix when the overriding communication goals are to enhance adequate understanding of product/service, convince and persuade prospects to purchase action. Further study to unveil the strengths of the rest of the media, is suggested. Key words: Advertising; Media; Marketing communication; Promotion

Using online search data to forecast new product sales

Search engines are rapidly emerging to be the ''go-to'' sites for consumers to learn more about a product, concept or a term of interest, irrespective of the initial channel in which the interest originated - text, radio, TV, multi-media channels, word of mouth, etc. In this paper we argue that data on the search terms used by consumers can provide valuable measures and indicators of consumer interest in a product, concept or a term. Such data can be particularly valuable to managers in gauging potential product interest in a new product launch context or consumption interest in the post-release context. Based on this premise, we develop a model of pre-launch search activity and link the pre-launch search behavior and product characteristics to early sales of the product, thus providing a useful forecasting tool. Applying the model in the context of motion pictures, we find that search term usage follows rather predictable patterns in the pre-launch and post-launch periods and the model provides significant power in forecasting release week sales as a function of pre-release search activity. With advertising data included in the model, we find that the pre-release search data offers additional explanatory and forecasting power, thus highlighting the ability of the search data to capture other factors, such as possibly word-of-mouth, in impacting early sales. We offer specific insights into how managers can use search volume data and the model to plan their new product release.

Chinese Newspaper Ownership, Corporate Strategies, and Business Models in a Globalizing World

This study takes Beijing Youth Daily (BYD), Beijing's largest newspaper in terms of advertising revenue and second largest in terms of circulation, as a case study to examine and analyze how globalization influences the ownership, corporate strategies, and business models of local newspaper organizations in China; and, thus, accelerates Chinese-style capitalism and media convergence. Declining advertising revenue and the loss of readers due to the digital revolution and the availability of multimedia news channels are global challenges that face newspapers around the world. BYD is no exception. In response, BYD has shifted from an exclusively state ownership model to a split or dual-track management model that has allowed foreign capital into the business operations while the party/state still retains ideological control over the news content. BYD has reoriented its corporate strategies and carried out structural reforms, building a media conglomerate via new titles, acquisitions, concentrations, and convergences; and developed its business models with advertising as a major revenue source. All these measures are market-oriented and intended to maximize newspaper profits by pursuing economies of scale and scope.

Evaluation of the interference of pulsed UWB signals over current services in CATV installations

This paper presents an application of ultra- wide band (UWB) technology, consisting on the injection of pulsed UWB signals on community antenna television (CATV) installations. This approach offers the cable installers the possibility for a wide range of new data and multimedia channels on existing CATV installations, with a minimum cost and without altering the transmission of the traditional radio and television channels. The goal of this study has been to estimate the signal levels for which no harmful interference exists for the currently deployed services. Simulations and practical experiments were undertaken, and are presented and discussed in this paper.
