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. 展开更多

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. 展开更多

Background:Tobacco use is a serious health concern in Albania.While the prevalence of tobacco smoking has traditionally been higher for men,the increasing prevalence of smoking for women is becoming a concern.The 2007 Tobacco Control policy mandated smoke-free indoor spaces,banned various forms of tobacco advertising,required written health warnings on packaging and levied excise taxes on cigarette sales.Since smoking behavior varies among different demographic groups,each group’s response to a uniform policy will differ,blunting the effectiveness of these efforts as a result.This study examines various socioeconomic,demographic and behavioral factors affecting both the likelihood and frequency of smoking in Albanian households in order to provide insights on targeting various populations more effectively.Methods:The study utilizes data from Albanian 2008-09 and 2017-18 Demographic and Health Surveys consisting of adults aged 15-49 years.The outcome variable includes respondents’current tobacco smoking behaviour and its frequency.The exposure variables include respondents’sociodemographic and lifestyle characteristics.We use a two-level random intercept model with the two-stage residual inclusion estimation method to determine the association between outcome and exposure variables.By including a time variable,we capture the change in smoking behavior during the 2009-2018 period.We also extend the analysis by assessing the differential influence of gender on the likelihood of smoking,both by income quintiles and education.Results:The results suggest that the likelihood of smoking decreased by 23%in 2017-18 compared to 2008-09,after controlling for various socioeconomic and demographic factors.Tobacco smoking is also found to be linked to alcohol consumption,with binge drinkers 59%more likely to smoke tobacco compared to moderate drinkers.We also found significant inter-quintile and inter-educational differences in smoking practices within each gender category.While the likelihood of tobacco smoking decreases with increasing wealth and educational attainment among men,the opposite(for wealth)or more involved(for educational attainment)patterns are true among women.Conclusions:To further enhance the effectiveness of the current Tobacco Control policy,the Government of Albania should target various demographic groups(such as poor males,rich and educated females)in a differentiated fashion. 展开更多

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. 展开更多

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. 展开更多

[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. 展开更多

[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. 展开更多

[Objective] The paper was to analyze the meteorological epidemic factors for occurrence and prevalence of tobacco bacterial wilt ( Ralstonia solanaca- rum), and to study control effects of different soil conditioners on the bacterial disease in Gacligongshan demonstration area of green, ecological, high quality tobac- co leaf production. [Method] The plots attacked by tobacco bacterial wilt over the years were selected and the incidence of the disease was periodically surveyed in tobacco growth period in 2012, 2103 and 2014, respectively. 10 d Effective accumulated temperature and rainfall were counted according to the meteorological data, and the relationship between meteorological factors and disease index was analyzed. The control effects of three kinds of soil conditioners "Zhuanggenfeng", refined fulvic acid and lime on tobacco bacterial wilt were tested. [ Result] The analysis results of meteorological factors showed that 10 d effective accumulated temperature and rainfall were positively correlated to disease index. The variation curve of 10 d effective accumulated temperature and rainfall reflected the change trend of disease index. The pH values were increased by 0.57, 0.50 and 0.72 respectively after applying "Zhuanggenfeng", refined fulvic acid and lime. The aver- age control effects on tobacco bacterial wilt were 60.74% -62. 18%, 53.05% -59.53%, and 48.59% -58.53%, respectively. [ Conclusion] 10 d Effective accumulated temperature and rainfall could be used as important reference for disease forecasting and controUing. The usage of soil conditioner has a certain preven- tion and control effect on tobacco bacterial wilt disease by forming soil conditions conducive to flue-cured tobacco growth but adverse to disease survival, which is an effective auxiliary method against the disease. 展开更多

Objective To assess the implementation of five key tobacco control policies in China: protection from second-hand smoke (SHS); offering help to quit; health warnings regarding tobacco use; the enforcement of bans on tobacco advertising, promotion, and sponsorship; and increasing tobacco taxes and prices. Methods Using 2010 Global Adults Tobacco Survey in China (GATS-China), 10 indicators are used to assess the implementation of five key tobacco control policies of MPOWER in China. Results Overall, 63.3% and 72.7% of adultsnoticed people smoking indoor workplaces and public places, respectively. Approximately 60% of smokers were not asked about their smoking habits and approximately 67% were not advised to quit on their visit to a health worker. Sixty percent of adults noticed health warning messages on cigarette packaging and in the media in the last 30 days, 63.6% stated that they would not consider quitting. Twenty percent of respondents noticed tobacco advertising, promotion, and/or sponsorship activities in the 30 days prior to the survey. Among them, 76.3% noticed the direct advertising and 50% noticed from TV programs. Although purchasing price of one pack of cigarettes ranged from 1 to 200 RMB, 50% of current smokers (about 150 million) spent 5 RMB or less on one pack of cigarette. The expenditure on 100 packets of cigarettes represents 2% of 2009 GDP per capita. Conclusion The average score for the implementation of the 5 policies of MPOWER in China is 37.3 points, indicating tobacco control policies in China is poor and there is a large gaps from the FCTC requirements. 展开更多
