Background- Communication messages today are all about influencing and persuading people. Two main types of messages can be seen when studying the healthy food trend on Instagram and how it is impacting attitude formation and change; these two are positive and negative messages. However, different communication messages are not the only deciders of attitude formation and change. There is one more significant factor that impacts attitude formation and change; this factor is identification with the message sender. Purpose- The purpose of this thesis is to identify whether positively or negatively themed messages on Instagram have a stronger impact on a person's attitudes regarding healthy food consumption. We will further examine if identification with the message sender additionally impacts attitude formation and change. Method- In order to fulfill the purpose of the thesis we used a qualitative research approach. We conducted interviews with 40 respondents that belonged to our main target group. Furthermore we conducted a robustness check with six respondents. All 46 respondents included in the qualitative study were Instagram users, and all the respondents in the main target group were students. Findings and Conclusion- After analyzing the empirical results together with suitable theories, some main conclusions could be drawn. The study demonstrated that positive communication messages are the preferred message type on Instagram. We further conclude that identification with the message sender does indeed have an additional impact on attitude formation and change. Based on this study we can say that communication messages and identification with the message sender work together in forming and changing attitudes regarding healthy food on Instagram. Practical Implications- This thesis gives valuable indications to companies, organizations and decision makers in order to direct marketing practices in terms of communication messages on social media, particularly Instagram. Moreover it gives insights for managers to be able to create communication messages that correspond to the expectations of the society. Keywords- Communication messages, attitude formation and change, identification with the message sender.

Thesis (M. A. (Communication Studies)) -- University if Limpopo, 2021 / This study was prompted by the number of people who die daily from tuberculosis (TB) in the study area. The study investigated the perceptions of Mokopane residents, and their level of understanding and knowledge of the disease, tuberculosis (TB). The aim of the study was to profile people’s perceptions of health beliefs, the causes of the increase and spread of TB and its prevention and their knowledge about TB awareness campaigns in the Mokopane area. Data was collected by means of both qualitative and quantitative methods. Ten (10) medical doctors who operate private practices in the Mokopane area were interviewed. Data was collected from four hundred and one (401) participants from both Sandsloot and Tshamahansi villages outside Mokopane. The major findings of this study showed that firstly residents have a firm belief that traditional methods cure TB; secondly, they are largely ignorant of TB, its prevention, and consequences; and lastly that there is a lack of TB related education.

Dealing with optimization problems with more than one objective has been an important research area in evolutionary computation. The class of multi-objective problems (MOPs) is an important one because multi-objectivity exists in almost all aspects of human life; whereby there usually exist several compromises in each problem. Multi-objective evolutionary algorithms (MOEAs) have been applied widely in many real-world problems. This is because (1) they work with a population during the course of action, which hence offer more flexible control to find a set of efficient solutions, and (2) real-world problems are usually black-box where an explicit mathematical representation is unknown. However, MOEAs usually require a large amount of computational effort. This is a sub- stantial challenge in bringing MOEAs to practice. This thesis primarily aims to address this challenge through an investigation into issues of scalability and the balance between exploration and exploitation. These have been outstanding research challenges, not only for MOEAs, but also for evolutionary algorithms in general. A distributed framework of local models using explicit niching is introduced as an overarching umbrella to solve multi-objective optimization problems. This framework is used to address the two-part question about first, the role of communication messages and second, the role of explicit niching in distributed evolutionary multi-objective optimization. The concept behind the framework of local models is for the search to be conducted locally in different areas of the decision search space, which allows the local models to be distributed on different processing nodes. During the optimization process, local models interact (exchange messages) with each other using rules inspired from Particle Swarm Optimization (PSO). Hence, the hypothesis of this work is that running simultaneously several search engines in different local areas is better for exploiting local information, while exchanging messages among those diverse engines can provide a better exploration strategy. For this framework, as the models work locally, they gain access to some global knowledge of each other. In order to validate the proposed framework, a series of experiments on a wide range of test problems was conducted. These experiments were motivated by the following studies which in their totality contribute to the verification of our hypothesis: (1) studying the performance of the framework under different aspects such as initialization, convergence, diversity, scalability, and sensitivity to the framework's parameters, (2) investigating interleaving guidance in both the decision and objective spaces, (3) applying local models using estimation of distributions, (4) evaluating local models in noisy environments and (5) the role of communication messages and explicit niching in distributed computing. The experimental results showed that: (1) the use of local models increases the chance of MOEAs to improve their performance in finding the Pareto optimal front, (2) interaction strategies using PSO rules are suitable for controlling local models, and that they also can be coupled with specialization in order to refine the obtained non-dominated set, (3) estimation of distribution improves when coupled with local models, (4) local models work well in noisy environments, and (5) the communication cost in distributed systems with local models can be reduced significantly by using summary information (such as the direction information naturally determined by local models) as the communication messages, in comparison with conventional approaches using descriptive information of individuals. In summary, the proposed framework is a successful step towards efficient distributed MOEAs.

El estudio examinó la posible influencia del lenguaje y lugar de origen de un lector en la comprensión de mensajes de comunicación en salud y en la formación de actitud e intención hacia la realización de una conducta preventiva. Un instrumento de medición con escala de comprensión de lectura, actitud e intención fue suministrado a un grupo de puertorriqueños y dominicanos N=40) residentes en San Juan, Puerto Rico. La escala de comprensión tenía dos textos en diversos niveles de dificultad (bastante fácil y medio) de acuerdo con la Fórmula de Legibilidad para el idioma español de Francisco Szigriszt Pazos. Se encontró que no hubo diferencia estadísticamente significativa (p>.05) entre la muestra en el nivel de dificultad bastante fácil, no obstante en el nivel de dificultad medio sí hubo diferencia estadísticamente significativa (p<.05). Los análisis reflejaron que la comprensión y actitud en conjunto no predicen de manera significativa el grado de intención para la adopción de una conducta preventiva de salud. / This study examines the possible influence of a reader's place of origin on the comprehension of health communication messages and on the formation of attitudes and intentions of preventive behavior. A measurement instrument with a reading comprehension, attitude and intention scale was administered to a group of individuals of Puerto Rican and Dominican origin (N=40) living in San Juan, Puerto Rico.The reading comprehension scale used two texts with different levels of difficulty (relatively easy and intermediate) in accordance with the Readability Formula for Spanish of Francisco Szigriszt Pazos. There was no statistically significant difference (p>.05) among the samplefor the relatively easy level of the reading test; however, for the intermediate level, there was a statistically significant difference (p<.05). Analyses showed that comprehension and attitude together do not significantly predict the degree of intention to adopt healthy preventive behavior.
