DEVELOPMENT AND VALIDATION OF A DISCRETE EVENT SIMULATION MODEL TO EVALUATE THE LONG TERM USE OF ELECTRONIC CIGARETTES IN US POPULATION

Saxena, Kunal 01 January 2015 (has links)
Introduction: Cigarette smoking is associated with lung cancer, cardiovascular disease, and chronic respiratory conditions. It is responsible for high mortality and morbidity risk in the US population. Smokers find sudden quitting difficult and it is reported that a large number of unassisted quitting attempts are eventually unsuccessful. Electronic cigarette or e-cig is a novel battery-driven, nicotine delivery product, currently being used as a smoking cessation tool by current and former smokers. Since its resemblance to a conventional cigarette, and its non-combustible nature, e-cig use has risen exponentially in the last few years. To address such public health issues, the US FDA is working on formulating regulations to manufacture, market, and distribute e-cigs has called for research evidence on the long term use of e-cig use. Objective: The objective of this study was to develop and validate a Discrete Event Simulation model to simulate the electronic cigarette (e-cig) use behavior, and to estimate the long term e-cig use prevalence, in different groups of the US population. Methods: The model population was generated from analyzing the National Health Interview Survey data from 2011-2013. The population was categorized into current, recent former, late former and never smokers. Population birth rates and death rates were applied using the 2012 US Census Bureau data. Model parametrization, transition probabilities and e-cig related risks were obtained and applied using cross sectional survey and longitudinal e-cig studies done on US population. The model was run for the period of 15 years and e-cig use prevalence at the end of the simulation period was estimated. Each simulation was replicated 100 times using Monte Carlo simulation approach. Model validation was performed by the use of null and extreme input values (internal validation), examining programing codes (debugging), verification by tobacco science and system analysis experts (structural and technical validation), comparison of model’s first year results with CDC reports (external validation). Conclusion: Total projected e-cig prevalence in the US population at the end of simulation of period was found to be around 19%. The results showed a gradual reduction in the number of conventional cigarette smokers and an increase in the e-cig users over the simulation period. Highest e-cig users were old, male, white and had less than high school level education. Sensitivity analyses of various model parameters showed that the e-cig prevalence was most sensitive to the impact and timing of policy implementation. As a novel nicotine delivery system, e-cigs are rapidly gaining acceptance in the US and recent reports have shown an exponential rise in the popularity of e-cig among minors and young adults. Our research provides empirical evidence that can be used by the scientific community and regulatory bodies to formulate regulations for marketing and sales of e-cigs in various sections of the population, where the prevalence is expected to rise in future. Our study can also guide the policy makers to introduce relevant policies at specific time points when the e-cig use is expected to rise.

An evaluation of the factors affecting consumer resistance to innovation diffusion of e-cigarettes among South African university students

Johnson, Nastasje January 2016 (has links)
Submitted in full fulfilment of the requirements for the degree of MASTER OF COMMERCE (Marketing) at the UNIVERSITY OF THE WITWATERSRAND 2015 / With an increase in the concern over the harmful effects of smoking traditional tobacco cigarettes, there has been an increase in the use of a smoking alternative considered to be a healthier option, namely the e-cigarette. Thus, it is of interest to understand certain factors surrounding the novelty, and this research has been conducted in terms of evaluating the predictors of the diffusion of innovations on consumer resistance towards the e-cigarette among South African university students, with the primary purpose being to research a gap in the South African e-cigarette market, and to utilise the results to better understand the overall market. The gap in prior research has been identified as what appears to be a lack of information regarding the South African e-cigarette market, and in particular, the predictors of consumer resistance, including relative advantage, compatibility, complexity, trialability, observability, and perceived risk. The study undertook a quantitative methodology in which 400 students from the University of the Witwatersrand were asked to complete a self-administered questionnaire. Data analysis was conducted using SPSS 22 and AMOS for structural equation modelling. The results indicate that three of the six hypotheses are supported. Thus, indicating that marketers should focus on applying relative advantage, complexity, and perceived risk to marketing strategies. This study contributes to existing literature and contextual knowledge regarding consumer resistance and the diffusion of innovation. The results further provide marketing practitioners with a better understanding on how to limit consumer resistance and how to improve product diffusion of the e-cigarette, subsequently improving the rate of adoption. However, future research is necessary for corroboration. / MT2017

Efterfrågans priselasticitet på cigaretter på kort- och lång sikt : En studie av effekten på cigarettskatten och cigarettpriset i Sverige mellan år 1996-2012

Jesper, Hamrén, Anna, Viktorsson January 2014 (has links)
The study examines the price elasticity of demand for cigarettes in the short- and long run in Sweden. The time period for the study is 17 years and covers the years 1996-2012. The results of the study shows that the price elasticity of demand for cigarettes in the long run is higher than in the short run for the Swedish consumers, which is in line with previous studies in the area. The fact that the price elasticity of demand for cigarettes is higher in the long run, indicates that the substitution effect has a significant impact on the price elasticity of demand for cigarettes in the long run. The study was conducted in two parts where the authors investigated the effect of cigarette tax on cigarette prices and in addition the cigarette prices impact on the demand for cigarettes in Sweden. The combined result of the study demonstrates that increasing the cigarette tax by 10 per cent means that the demand for cigarettes is reduced by 5 per cent, while government revenues from the cigarette tax will increase by 4.5 per cent. The result in this paper shows why the state's incentive to raise the cigarette tax is twofold, since a tax increase will generate health benefits through reduced consumption and generate increased revenues to the state. These incentives are also shown to have a greater impact in the long term. / Studien undersöker efterfrågans priselasticitet på cigaretter på kort- och lång sikt i Sverige. Tidsperioden för undersökningen är 17 år och omfattar åren 1996-2012. Studiens resultat visar att efterfrågans priselasticitet på lång sikt är högre än på kort sikt för de Svenska konsumenterna, vilket ligger i linje med tidigare studier inom ämnet. Det faktum att priselasticiteten för cigaretter är högre på lång sikt indikerar på att substitutionseffekten har betydande effekt för efterfrågans priselasticitet på cigaretter på lång sikt. Studien har genomförts i två delar där författarna undersökt cigarettskattens effekt på cigarettpriset och i sin tur cigarettprisets effekt på efterfrågan på cigaretter i Sverige. Det kombinerade resultatet i studien påvisar att en ökning av cigarettskatten med 10 procent medför att efterfrågan på cigaretter minskar med 5 procent, samtidigt som statens intäkter från cigarettskatten ökar med 4,5 procent. Resultatet i denna uppsats visar därför att statens incitament till att höja cigarettskatten är tvådelad, då en skatteökning genererar hälsovinster genom minskad konsumtion samt genererar ökade intäkter till staten och att dessa incitament har en större påverkan på lång sikt.

Kentucky pharmacists' opinions and practices related to the sale of cigarettes and alcohol in pharmacies

Stephenson, Stefanie L. January 2000 (has links)
The objective of the study was to augment important findings from a 1996 statewide survey of Indiana pharmacists regarding their opinions and practices related to the sale of cigarettes and alcohol in pharmacies. More specifically, this study was designed (1) to determine opinions and practices of Kentucky pharmacists' related to the sale of cigarettes and alcohol; (2) compare these findings with results from the Indiana study; and (3) to gather information on health promotion activities by Kentucky pharmacists. A structured survey questionnaire was designed and reviewed by a jury of experts and subsequently administered to half of the 1182 pharmacies in Kentucky. Collected data were analyzed using descriptive and inferential statistical methods.Findings reveal that 45% of responding pharmacists sell cigarettes in their stores although 88% think their stores should not sell cigarettes. Approximately 34% of pharmacies in non-dry counties sell alcoholic beverages while more than four-fifths of the pharmacists (81%) think pharmacies should not sell alcoholic beverages. After adjusting by type of pharmacy, no statistical difference was found in retail-chain pharmacy sales of cigarettes and alcohol in either Kentucky or Indiana. However, independent pharmacies in Kentucky were less likely to sell cigarettes and alcohol compared to independent Indiana pharmacies. Study results also revealed that most pharmacists agree the use of cigarettes and alcohol are important causes of morbidity and pre-mature mortality and that pharmacists should play a role in health promotion and disease prevention through their relationship with the public. / Department of Physiology and Health Science

Branded and non-branded tobacco counter-advertisements : an experimental study of reactance and other maladaptive and adaptive coping responses

Wehbe, Michelle S, University of Lethbridge. Faculty of Management January 2012 (has links)
An experiment was done to investigate whether or not there is a need to treat smokers and non-smokers as separate target audiences when creating tobacco counter-advertisements. The Extended Parallel Process Model (Witte, 1992) and Reactance Theory (Brehm, 1966) were used to guide the development of predictions. The study revealed that social marketers need to have different advertising tactics for smokers and non-smokers, since smokers have reported more maladaptive coping responses and fewer adaptive coping responses than non-smokers. Moreover, based on the fact that a smoker’s brand forms an essential part of their self-identity (Goldberg et al., 1995) the experiment was also designed to see if smokers would have differing levels of reactance and other maladaptive coping responses if they saw a counter-advertisement attacking their brand, one attacking a competing brand, and a non-branded one. The study did not reveal any significant differences in reactions among the three conditions. / x, 125 leaves : ill. ; 29 cm

[en] CREATION, MOVEMENT AND NEGOTIATION OF MEANINGS IN NON-CONSUMPTION: A STUDY OF ABANDONMENT OF AUTOMOBILE AND CIGARETTE CATEGORIES / [pt] CRIAÇÃO, MOVIMENTO E NEGOCIAÇÃO DE SIGNIFICADOS A PARTIR DO NÃO CONSUMO: UM ESTUDO DO ABANDONO DAS CATEGORIAS DE AUTOMÓVEL E CIGARRO

MARIBEL CARVALHO SUAREZ 01 March 2011 (has links)
[pt] No campo do comportamento do consumidor, muito se estudou sobre o que motiva os indivíduos a adotarem determinado consumo. As decisões de abandono, entretanto, são um tema praticamente inexplorado, ainda que capazes de proporcionar importantes aprendizados para empresas, governos e organizações não governamentais no contexto atual de intensa competição, críticas ao consumo e questionamento dos seus impactos no meio ambiente. O presente trabalho contribui com o conhecimento da área através da investigação dos significados que motivam e são criados a partir da escolha deliberada de abrir mão de algo anteriormente consumido (abandono). O trabalho utiliza-se de metodologia qualitativa, no processo de coleta e análise dos dados, gerados a partir de entrevistas em profundidade com 29 ex-consumidores de duas categorias bastante distintas: cigarros e automóveis. Os resultados sugerem três conjuntos de fatores que resultam nessa decisão, delineando três tipos de abandono: 1) abandono contingencial; 2) abandono posicional; e 3) abandono ideológico. A presente pesquisa preenche ainda uma lacuna do campo ao estudar os rituais de não consumo no abandono e evidenciar que os indivíduos se apropriam de significados relacionados aos produtos não apenas através da sua compra e uso, mas também através de sua abstenção. No abandono, o indivíduo abre mão da funcionalidade relacionada ao produto, no entanto, as associações simbólicas continuam sendo usadas, criadas e manipuladas mesmo depois que este acontece. Complementando o esquema conceitual de McCracken (2003), onde são destacados os rituais de consumo (troca, posse, arrumação e descarte), o estudo sugere cinco tipos de rituais de abandono (de descontaminação, esfriamento, luto, reforço e defensivos). A pesquisa destaca ainda o abandono como ritual de passagem, onde essa decisão termina por sinalizar mudanças na condição social dos indivíduos, evidenciando não apenas aquilo que o consumidor se torna, mas, em alguns casos, o que gostaria de ser, concretizando, mesmo que provisoriamente, esperanças e ideais. O trabalho destaca a importância do contexto de reforço ou questionamento ao consumo para a negociação de significados que se estabelece a partir do abandono. No caso de produtos cujo consumo é questionado, o abandono, em geral, representa o movimento de distanciamento dos significados do produto e da identidade do consumidor. No caso dos produtos cujo consumo é reforçado no ambiente social, como o automóvel, o abandono abre tanto a possibilidade de estigmatização quanto de diferenciação positiva, onde o indivíduo cria novos significados, identidades almejadas e se aproxima de grupos de referência positivos. A pesquisa evidencia, assim, a complexidade dos movimentos associativos e dissociativos operados pelo abandono. Por fim, o trabalho destaca como o contexto influencia as dinâmicas de movimento e negociação dos significados que se estabelecem a partir rituais de abandono nos planos privado, de grupo e coletivo e sua influência na transformação dos conteúdos simbólicos contidos nas categorias de produto. / [en] In the field of consumer behavior, much research has been conducted on what motivates individuals consume a given item. The decision to abandon consumption, however, is a largely unexplored topic, even though it can provide important insights for businesses, governments and nongovernmental organizations in the current context of intense competition, criticism of consumption and questioning of the impact of consumption on the environment. This work contributes to the body of knowledge through investigation of the meanings that motivate and that arise from the deliberate choice to give up something previously consumed (abandonment). The work uses a qualitative methodology in the process of collecting and analyzing data generated from in-depth interviews with 29 former consumers of two very distinct categories: cigarettes and automobiles. The results suggest three sets of factors that result in the decision and outline three types of abandonment: 1) contingency abandonment; 2) positional abandonment; 3) ideological abandonment. This research also fills a gap in the field in its study of the rituals of non-consumption in abandonment and suggests that individuals appropriate meanings related to products, not only through their purchase and use, but also by abstaining from them. In abandonment, the individual gives up the functionality ascribed to the product; however, the symbolic associations continue to be used, created and manipulated even after abandonment. Complementing the model of McCracken (2003), which explores the rituals of consumption (exchange, possession, grooming and divestment), the study proposes five types of abandonment rituals (decontamination, cooling off, mourning, reinforcement, and defenses). The research also investigates abandonment as a rite of passage, where the decision eventually signals changes in the individuals social condition, reflecting not only what the consumer is becoming, but in some cases, what they wish to become, thereby fulfilling – even if temporarily – hopes and ideals. The paper highlights the importance of the context of reinforcement or questioning of consumption for the negotiation of meaning that is derived from abandonment. In the case of products whose consumption is being questioned, abandonment, in general, represents a distancing from the product s meaning and its identity with the consumer. In the case of products whose consumption is reinforced in the social environment, such as the automobile, abandonment opens both the possibility of stigmatization and of positive differentiation, where the individual creates new meanings, desired identities and approaches positive reference groups. The study thus underscores the complexity of associative and dissociative movements operated by abandonment. Finally, the paper discusses how the context influences the dynamics of movement and negotiation of meanings that grow out of the rituals of abandonment in private, group, and collective plans and their influence on the transformation of the symbolic content of product categories.

Comparative risk assessment of tobacco smoke constituents using the margin of exposure approach: the neglected contribution of nicotine

Lachenmeier, Dirk, Baumung, Claudia, Rehm, Jürgen, Franke, Heike 18 November 2016 (has links)
Nicotine was not included in previous efforts to identify the most important toxicants of tobacco smoke. A health risk assessment of nicotine for smokers of cigarettes was conducted using the margin of exposure (MOE) approach and results were compared to literature MOEs of various other tobacco toxicants. The MOE is defined as ratio between toxicological threshold (benchmark dose) and estimated human intake. Dose-response modelling of human and animal data was used to derive the benchmark dose. The MOE was calculated using probabilistic Monte Carlo simulations for daily cigarette smokers. Benchmark dose values ranged from 0.004 mg/kg bodyweight for symptoms of intoxication in children to 3 mg/kg bodyweight for mortality in animals; MOEs ranged from below 1 up to 7.6 indicating a considerable consumer risk. The dimension of the MOEs is similar to those of other tobacco toxicants with high concerns relating to adverse health effects such as acrolein or formaldehyde. Owing to the lack of toxicological data in particular relating to cancer, long term animal testing studies for nicotine are urgently necessary. There is immediate need of action concerning the risk of nicotine also with regard to electronic cigarettes and smokeless tobacco.

Influencer Endorsements of E-Cigarette Brands on Instagram : A study of Gen Z perception of influencers endorsing e- cigarette brands on Instagram

Grover, Isha, Jauregui, Ander January 2023 (has links)
The widespread use of social media platforms and the emergence of influencer marketing have revolutionized brand-consumer interactions, particularly among the younger demographic. In line with this trend, the influence of e-cigarette influencers on Generation Z (Gen Z) has become a prominent area of research. As influencer marketing continues to thrive and the e-cigarette industry experiences significant growth, it is imperative to comprehend how these influencers shape Gen Z's perception of influencers endorsing e-cigarette brands. Therefore, this study aims to examine the perception of Gen Z towards Instagram influencers in the United States who endorse e-cigarette brands. By exploring the perspectives of Gen Z, this research seeks to gain insights into the potential impact of these influencers on Gen Z's attitudes and behaviours regarding e-cigarettes. The study was based on the theory of source credibility and celebrity endorsement. The study adopted a qualitative research approach and employed in-depth interviews and netnography as methodology. A total of eleven in-depth interviews were conducted with participants from Gen Z who possessed knowledge and familiarity with e- cigarettes. Additionally, through netnography, comments from publicly available Instagram posts of the selected e-cigarette influencers were collected and examined over a period of three years. The findings highlight that Gen Z generally holds a positive perception of e-cigarette influencers on Instagram, perceiving them as credible sources of information and inspiration, thereby influencing their attitudes and behaviours concerning e-cigarettes. These insights have practical implications for e-cigarette brands aiming to engage Gen Z through influencer marketing, emphasizing the importance of trust and expertise in influencer-generated content. However, the study also highlights potential societal implications, including the potential for i increased e-cigarette consumption and ethical concerns surrounding the influence of trustworthy influencers on underage users. In conclusion, the study proposes avenues for future research, such as conducting surveys with larger sample sizes and exploring perceptions of e- cigarette influencers on alternative social media platforms like TikTok.
