A Mathematical Theory of Communication with Graphs and SymbolsArt Terlep (19194136), T. Arthur Terlep (10082101), T. Arthur Terlep (10082104) 25 July 2024 (has links)
<p dir="ltr">This work will introduce a channel conceptualization and possible coding scheme for Graph-and-Symbol (GS) Communication. While Claude Shannon’s mathematical model for communication employed graphs to describe relationships and confusability among traditional time-sequenced signals, little work as been done to describe non-linear communication <i>with</i> graphs where we transmit and receive physical structures of information. The principal contribution of this work is to introduce a mathematical framework for communication with graphs which have symbols assigned to vertices. This looks like a molecule, and so we may think of these messages as coded forms of molecular communication.</p><p dir="ltr">At this time, many problems in this area will (and may remain) computationally intractable, but as the field of graph theory continues to develop, new tools and techniques may emerge to solve standing problems in this new subfield of communication.</p><p dir="ltr">Graphs present two difficulties: first, they contain ambiguities among their vertices and do not have an <i>a priori</i> canonical ordering, and second, the relationships among graphs lack structural regularities which we see in traditional error control coding lattices. There are no Galois fields to exploit over graph-based codes as we have with cyclic codes, for example. Furthermore, the shear number of graphs of order n grows so rapidly that it is difficult to account for the neighborhoods around codewords and effectively reduce communication errors which may occur. The more asymmetric a graph is, the more orderings on symbols it can support. However, asymmetries complicate the computation of channel transition probabilities, which are the cornerstone of all communication theory.</p><p dir="ltr">In the prologue, the reader will be introduced to a new educational tool for designing traditional binary cyclic codes.</p><p dir="ltr">1 through 10 will detail the development of Graph-and-Symbol (GS) Commu- nication to date followed by two example codes which demonstrate the power of structuring information on graphs.</p><p dir="ltr">Chapter 13 onward will review the preliminary work in another area of research, disjoint from the main body. It is included here for posterity and special interests in applying graphs to solving other problems in signal processing. It begins with an introduction of spacetime raythic graphs. We propose a new chamfering paradigm for connecting neighboring pixels which approximates solutions to the eikonal equation. We show that some raythic graphs possess structures with multiple, differing solutions to eikonal wavefront propagation which are essential to the construction of the Umbral Transform. This umbral transform emulates ray casting effects, such as shadows and diffraction within an image space, from a network-flow algorithm.</p><p dir="ltr">This work may be duplicated in whole or in part for educational purposes only.

Produzione e consumo sostenibili: l’appello per il “decennio d’azione” / SUSTAINABLE PRODUCTION AND CONSUMPTION: A CALL FOR THE "DECADE OF ACTION" / Sustainable production and consumption: a call for the “decade of action”BERNARDI, ALBERTA 11 May 2021 (has links)
Le Nazioni Unite hanno espresso la necessità che aziende e consumatori si orientino ad una maggiore sostenibilità. Questa tesi parte da tale constatazione e analizza l’impatto che la sostenibilità ha sulle strategie aziendali, sull’orientamento all’innovazione di prodotto e processo e, infine, sulle relazioni che si sviluppano nella filiera produttiva. Inoltre, viene analizzata la relazione tra le strategie di marketing e le scelte di consumo sostenibili.
Vengono analizzate, innanzitutto, due aziende di moda. L’analisi qualitativa mira a definire cosa sia per loro la sostenibilità, in che modo questa le metta alla prova e cosa possa garantire il successo duraturo di una strategia sostenibile. Viene successivamente analizzato un campione di 1104 intervistati per comprendere come le aziende di moda dovrebbero comunicare il loro impegno nella sostenibilità, attraverso mezzi di comunicazione specifici e ben definiti, soprattutto a quei consumatori che sono propensi - ma non del tutto convinti - ad acquistare abbigliamento sostenibile.
Infine, viene analizzato un campione di 99 aziende vinicole a cui è stato sottoposto un questionario per capire se esiste una relazione tra la collaborazione tra i partner lungo la filiera produttiva e la performance sostenibile dell’impresa.
I risultati evidenziano i fattori che orientano le strategie sostenibili delle aziende vinicole e della moda, e il comportamento dei consumatori. Vengono evidenziate soluzioni pratiche che possano accompagnare le aziende verso un crescente orientamento alla sostenibilità. / This doctoral thesis aims at shedding light on the United Nations’ call-to-action for producers and consumers who, jointly, have to contribute to sustainable development. The aim is to investigate the impact of sustainability on companies’ strategies by exploring their orientation towards process and product innovation, and the consequent business relationships that develop along the supply chain. Furthermore, the thesis seeks to investigate the role of some marketing strategies and the consumers’ sustainable attitudes.
Two fashion companies are analyzed to explore what sustainability is for them and how they are challenged by sustainability concerns. Propositions are formulated that can help companies define long-term and effective sustainability-oriented strategies. A sample of 1104 respondents is then analyzed to understand how sustainability-oriented fashion companies should communicate their commitment, through specific and well defined communication tools, to those consumers who are positively disposed towards sustainable clothing but are still afraid of these “new” products.
Lastly, a sample of 99 wine companies is analyzed. They were asked to answer a questionnaire whose purpose is to understand if there is a relationship between collaboration among partners along the supply chain and sustainable performance.
Results allow for a better understanding of the factors driving sustainable strategies of fashion and wine companies, and consumer behavior. Practical solutions are highlighted.

Claims Of Mistaken Identity: An Examination Of U.S. Television Food Commercials And The Adult Obesity IssueDelgado, Cristina 01 January 2009 (has links)
Obesity is one of the major public health issues in the United States, often regarded as part of a global crisis. Companies invest billions of dollars each year towards television advertising campaigns aimed at convincing audiences how their ground-breaking discovery 'battles the bulge' or somehow offers an increased health benefit. This study examined how advertisers presented health-related claims, including health and nutrient-content claims, in U.S. adult-targeted television food commercials. The claims were compared to FTC, FDA, and USDA laws, regulations, and recommendations. A content analysis of food advertising was conducted of commercials from major and cable network programs broadcast during prime-time in the first quarter of 2009. The majority of claims match current regulations when compared to Federal references. The results show that Nutrient and Wellness claims were the most frequently cited. The type of benefit, Healthy Eating, emerged almost 3 times more than any other benefit type. This is also similar to those results which suggest advertisers' intentions were to promote overall wellness in their content delivery. As such, the Wellness Approach was identified and conceptualized, leading towards full development of a Wellness Effect theory. Implications and future research opportunities are discussed on both a theoretical and practical level.

A customised proactive crisis communication process framework for secondary educational institutions in Kenya : a cross-sectional exploration of students' strike in Mirangine Sub-CountyNjenga, Wilfred Muigai 02 1900 (has links)
Text in English, abstracts and keywords in English, Afrikaans and Zulu / Secondary educational institutions need to constantly scan their environment for crises that could hamper their operations and hinder the achievement of their organisational objectives. These institutions should also engage their strategic stakeholders in a mixed motive communication to collaboratively discuss the crises and find amicable solutions; thereby avoiding crises like the proliferating student strikes in secondary educational institutions in Kenya. This study explored the need for a customised Proactive Crisis Communication Process (PCCP) framework for secondary educational institutions in Kenya to avoid student strikes.
A two-phased approach was adopted to collect the data. The first phase involved 12 one-on-one semi-structured interviews with the principals of the secondary educational institutions in Mirangine Sub-County, while the second phase involved five focus group discussions with the students of Ruiru Secondary School. The results indicated that student strikes in secondary educational institutions in Kenya were proliferating and that despite this, these institutions lack proactive measures to avoid strikes. Hence, this study posited a PCCP framework that proposed various proactive measures to avoid student strikes in secondary educational institutions in Kenya. / Sekondêre opvoedkundige instellings moet konstant hul omgewing ondersoek vir krisisse wat hul bedrywighede kan belemmer en die bereiking van hul organisatoriese doelwitte kan verhinder. Hierdie instellings moet ook hul strategiese belanghebbers by gemengdemotief- kommunikasie betrek om gesamentlik die krisisse te bespreek en minlike oplossings te vind; en sodoende krisisse soos die toenemende studentestakings in sekondêre opvoedkundige instellings in Kenia te vermy.

Emotional appeals in UK banks' print advertisementMogaji, Emmanuel January 2016 (has links)
The unprecedented turbulence and uncertainty experienced in global economic and financial markets because of the 'credit crunch' has had a damaging impact on consumer confidence. Trust and credibility have been eroded as many customers feel let down by the banks suggesting the need for banks to rebuild constructive dialogue and long-term, meaningful relationships with their customers again. Though financial service, in this case, is considered a utilitarian service, based on the fact that money is needed to support people‘s daily activities, the present state of financial service has suggested the need for banks to appeal to consumers‘ emotions with the aim of improving their reputation. Also, the competition within the industry also could suggest the need to adopt an emotionally appealing advertisement strategy as emotions are known to play an influential role in building robust brand preference. This study builds on the communication theory, meaning transfer theory and consumer involvement theory, to understand the messages the banks are sending out and to elicit consumers‘ emotional reaction. One thousand, two hundred and seventy-four UK bank advertisements in nine national newspapers were content-analysed to identify the emotional appeals presented by the banks. The perception of these appeals and their associated meanings were sought through semi-structured interviews with 33 participants in London and Luton. The results of the analysis indicated that UK Banks are utilising emotional appeal in their advertisements to reach out to the consumers to convince them to upgrade their account, to open an additional account or switch their account. The most predominantly used appeals were relief and relaxation followed by excitement and happiness or satisfaction with the bank, and finally, security and adventure. However, variations were found in different financial products that employed emotional appeals. It was found that high-involvement products such as mortgages and loans used fewer emotional appeals. Both bank groups - high street banks, including the big four (Barclays, HSBC, Lloyds and RBS) and non-high street banks, such as the new entrants, supermarket brands, and online banks were using emotional appeals. However, it is acknowledged that the communication strategies between these banks could be different as the non-high street banks are more likely to repeat and publish the same messages across many newspapers, instead of publishing different emotionally appealing advertisements. Though consumers acknowledged these emotional appeals in the advertisements, they were more concerned about their relationship with the banks as they don‘t rely on advertisements to make a financial decision. Rather, recommendations from families, friends and associates and also branch location are more important when deciding on which bank to choose. The lack of congruency between financial services and emotional appeals in advertisements is also observed as customers are more likely to be persuaded by rational appeals however this study has not completely ruled out emotional appeals in bank advertisements as the use of both types of appeals is recommended. The study provides important theoretical and managerial contributions to understanding how the consumers understand meaning-embedded advertisements produced by the banks. Managers will be able to consider the implications of advertisements in enhancing their brand equity and building relationships with customers in anticipation that, by word of the mouth and established relationship, their bank‘s reputation will be enhanced. Limitations of the study and opportunities for future research are identified.
