Tobacco Control Intervention:A Comparative Multimodal Discourse Analysis of Video Advertisements in China and Australia

Significant differences in tobacco-control initiatives and achievements between Australia and China have been witnessed in the world,despite the fact that thecountries share the Asia-pacific region and have intimate relationships.The smoking rate in Australia has been on a downward trend since the 1980s and therefore Australia has been portrayed as a“dark market”by global tobacco industry companies.However in China,cigarette smoking is the chief killer that causes deadly health risks to both direct users of tobacco and people exposed to second-hand smoke.Non-communicable diseases due to this have caused great burden to the national medical resources.As a vital intervention tool of mass media campaign,public health advertisements on tobacco-control have played an important role in influencing the cognition and behavior of recipients.This study aims to compare the strategies adopted by the advertisements in Australia and China through corpus-driven multimodal discourse analysis to conduct quantitative analysis and qualitative case study.The results of comparative analysis indicate different pathways of tobacco-control advertisements constructions in the two countries that Australian tobacco-control advertisements achieved better in terms of health communication intervention to encourage cessation among smokers and reduce smoking initiation among potential smokers at the population level.To be compared,Chinese tobacco-control advertisements placed a heavier emphasis on the health hazards caused by second-hand smoking to protect people from the attributable morbidity and mortality.From the perspective of content theme,this study argues that Chinese tobacco-control advertisements should shift the focus to the health damage of smoking to smokers which is more targeted and fundamental.From the perspective of multimodal presentations of the video advertisements,a more prominent demonstration of the health damage is recommended.Moreover,this study argues that cultural-oriented strategies should be developed in the tobacco-control advertisements if considering the cigarette sharing and gifting social phenomenon in the Chinese society.

Impact of Village-based Health Education of Tobacco Control on the Current Smoking Rate in Chinese Rural Areas

The number of smokers in Chinese rural areas is more than 200 million, which is twice that in cities. It is very significant to carry out tobacco control interventions in rural areas. We performed this community intervention study to evaluate the efficacy of village-based health education of tobacco control on the male current smoking rate in rural areas. The population of this study was the males above 15 years old from 6 villages in rural areas. The villages were randomly assigned to intervention group or control group（3 villages in each group）. Self-designed smoking questionnaire was applied. The intervention group received the village-based health education of tobacco control for one year. The primary outcome measurement was the male current smoking rate. In the baseline investigation, completed surveys were returned by 814 male residents from the control group and 831 male residents from the intervention group. The male current smoking rate in the control group and the intervention group was 61.2% and 58.5%, respectively, before intervention. There was no significant difference between these two groups（P〉0.05）. After one-year intervention, the current smoking rate in the intervention group（51.2%） was significantly lower than that in the control group（62.8%）（P〈0.001）. Our study suggested that the village-based health education of tobacco control was effective in lowering the male current smoking rate in rural areas, which could be a suitable and feasible way for tobacco control in the Chinese rural areas.

Does higher tax rate affect tobacco usage?Unravelling the nexus between tobacco regulatory control and public health concern

Objectives:Bangladesh stands as a prominent global consumer of tobacco,with alarming consequences on public health.The Global Adult Tobacco Survey reported that tobacco consumption claimed over 126000 lives in 2018,contributing to 13.5%of all deaths in the country.This study aims to explore the effectiveness of higher tax rates and tobacco use regulation as control mechanisms in mitigating tobacco consumption and health care cost burden,with a particular emphasis on its implications for public health.Methods:This study is based on the annual time series data over the period 2000-2020.The study employs the ordinary least square method to analyze the quantitative confirming the stationarity of data at level.This research uses different models to investigate individual effects and combined effects on both tobacco consumption and tobacco health care cost burden.Results:The study finds a negative relationship between tobacco tax rate and tobacco consumption.More specifically,the higher tax rate of tobacco(low(β=-0.3495),medium(β=-0.2319),high(β=-0.9033),premium(β=-0.7322),filtered(β=-0.2114),and non-filtered(β=-0.3452)categories)is significant to reduce tobacco use at 1%level of significance.The study finds similar results when it applied tobacco retail price instead of tobacco tax rate as the independent variable.Finally,the study investigates the impact on health care cost through tobacco consumption,tobacco control law,growth rate,export-import,and tobacco production.The results indicate that tobacco consumption,export-import,and tobacco production increases health care cost burden while tobacco use regulatory decreases it.By reducing tobacco consumption,higher taxes and tobacco use regulation contribute to alleviating the burden on the healthcare system,promoting healthier lifestyles,and aligning with global health objectives.Conclusions:Higher tax rate on tobacco products is necessary to increase the retail price so that tobacco users cannot consume tobacco.Specific tax and uniform tax base are needed so that tobacco users cannot switch to lower priced brands.Tobacco control laws need to revised and proper implementation should be ensured as well,to achieve the goal of tobacco free Bangladesh by 2040.Tobacco-related diseases,responsible for a significant proportion of deaths in the country,could witness a considerable decline with the successful implementation of higher tax rates and tobacco use regulation.This study provides insights that not only contribute to the economic discourse but also accentuate the broader public health benefits arising from effective tobacco taxation policies.

Grappling With Tobacco Control

It's reported that the British House of Commons passed a bill February 14 to ban smoking in every pub, club and indoor public space in England. The legislation is now submitted to the upper House of Lords. If passed, it will become law by mid-2007. With the ban, Britain joins Ireland, Finland, Italy, New Zealand, Norway, South Africa, Spain, Sweden and several U.S. states and cities, all of which have restricted smoking in public places in recent years.

Building Blocks for Tobacco Control

The tobacco epidemic is a global challenge demanding concerted global and national action. Recognizing that globalization is accelerating the epidemic’s spread and perceiving the limits of national action to contain a public health problem with transnational dimensions, Member States of the World Health Organization negotiated and adopted a unique public health treaty for tobacco control. Today, the WHO FCTC contains the blueprint for coordinated global action to address one of the most significant risks to health.

Integrated Biological Control of Tobacco Bacterial Wilt (<i>Ralstonia solanacearum</i>) and Its Effect on Rhizosphere Microbial Community

Biological control agents and soil amendments have been applied to control tobacco bacterial wilt, but the mechanism is not well-known. In the present study, a field experiment was performed to investigate the soil physicochemical properties, disease index (DI) and disease incidence of tobacco bacterial wilt, and rhizosphere microbial community. The results show that the control efficacy of single application of antagonistic bacteria and calcium cyanamide was 46.43% and 51.92%, respectively. While the combined control efficacy of antagonistic bacteria and calcium cyanamide was 65.79%. Besides, the combined application of antagonistic bacteria and calcium cyanamide could increase soil pH, total N alkaline N, and exchangeable Ca, which were negatively associated with the microbial diversity, soil-borne pathogenic microorganisms, and incidence of tobacco bacterial wilt. Additionally, the combination of antagonistic bacteria and calcium cyanamide can improve the proportion of some antagonistic microbial species, and these antagonistic microbial species were inversely associated with the DI of tobacco bacterial wilt. In conclusion: The integrated measure may influence soil microbial communities through enhancing soil physicochemical properties and rebuild healthy soil microbial community structure to mitigate tobacco bacterial wilt. The current study presented valuable insights into the mechanisms enhancing soil health in the integrated measure.

Occurrence Regularity and Control of Tobacco Mosaic Virus (TMV) in Wuxi Tobacco Area of China in 2011

On the basis of general situation and new characteristics of tobacco mosaic virus （TMV） in Wuxi tobacco area in 2011, the paper expounded the objec-tive reasons of TMV via systemic investigation, field experiment and date sorting. Meanwhile, combined with mcteorological conditions and results of systemic inves-tigation, the study especially analyzed meteorological conditions, outbreak and prevalence regularity of TMV and control efficacy of chemical reagents against TMV. The results showed that climatic conditions were the main conditions affecting TMV. There were three occurrence peaks of TMV in 2011, as a result of meteorologi-cal conditions of the months from April to June. The peaks were concerned with a wide range of rainfall about half a month before, low temperature, high humidity and scant sunshine and temperature jump after rain. The results of control effects showed that the chemical reagents could obviously prevent TMV, but once tobacco plants were infected, spraying chemical reagents would not have effective control effect against TMV.

Effects of Early Infection of Tobacco Mosaic Virus on Photosynthetic Proteins and Its Control

[Objectives] This study was conducted to explore the optimal period of TMV control and the physiological sites that interfere with TMV infection. [Methods] Proteome analysis was performed on the host tissues(tobacco plants) at different time periods of viral infection, to verify the changes in the expression of differential protein genes and N and PR1-a in the photosynthetic pathway and porphyrin metabolism and chlorophyll metabolism pathways in proteome; and the tobacco plants were treated with different preparations. [Results] The expression levels of N and PR1-a in the tobacco leaves treated with preparation B reached the highest level, and the effects on the expression levels of the differential protein genes were also the most significant. The control effects of the preparations were tested by the half-leaf method, and the results showed that preparation B had a significant control effect against the early infection of the virus.[Conclusions] This study lays a foundation for the prevention and control of tobacco mosaic virus on crops.

Control Effects of Different Agents on Tobacco Mosaic Virus Disease

[Objectives] This study was conducted to screen out suitable agents for controlling tobacco mosaic virus disease and the best control period in Zhangzhou tobacco area, providing a theoretical basis for the control of virus diseases, thereby improving the quality of flue-cured tobacco and the income of tobacco farmers. [Methods] The effects on tobacco mosaic virus disease under the interaction between different agents and different application periods were investigated. The incidence of tobacco mosaic virus disease was investigated, and its control effect was analyzed. [Results] Different agents and different application periods had different control effects on tobacco mosaic virus disease. The incidence of tobacco mosaic virus disease: At 30 and 45 d after transplanting, the incidences of A2B1 treatment were the lowest, at 0.85%, 1.71%, respectively;and at 60 d after transplanting, the incidence of A3B1 treatment was the lowest, only 10.68%. The control effect: At 30 and 45 d after transplanting, A2B1 treatment had better control effects, reaching 79.39% and 73.06%, respectively. [Conclusions] 3% hypersensitive protein sprayed at 1 d before transplanting and 7 and 15 d after transplanting achieved the best effect, followed by 10% ningnanmycin sprayed at 1 d before transplanting and 7 and 15 d after transplanting. In tobacco production, it is recommended to apply 1 000 times dilution of 3% supersensitive protein microgranules for three times(at 1 d before transplanting and 7 and 15 d after transplanting), which can effectively prevent tobacco mosaic virus disease.
