Plain Packaging, Pictorial Warnings and Tobacco Products: An Empirical Assessment

Although tobacco marketing is restricted, tobacco product packaging continues to communicate brand imagery, thereby maintaining brand salience and potentially reducing the impact of health warnings. This study used respondent conditioning theory to predict how disruption of brand imagery would affect the attractiveness of known, unknown and generic tobacco packages. A best-worst study found that familiar branding offset the negative connotations created by a pictorial warning label (PWL). These are the first findings to document the combined effect of PWLs and plain packaging; they suggest generic packs will stimulate cessation attempts and deter smoking initiation

Risks, Benefits and DTC - An Analysis of Information Formats

Critics of direct to consumer prescription medicine advertising (DTC) claim it is unbalanced because benefit information features more prominently than risk information, and that it thus fails to meet the high standards of social responsibility called for in regulatory codes. We used respondent conditioning theory to examine whether variations in risk information format could improve recall of benefits, side effects and contra-indications in print DTC advertisements. A best-worst study confirmed striking differences in preference for varied information formats, while a second study found that visual heuristics increased recall of both risk and benefit information. The findings question marketers reluctance to provide easily accessible risk information and suggest prominent drug information panels may discharge manufacturers social responsibilities while simultaneously improving the effectiveness of their promotions

Two endosomal NHX-type Na+/H+ antiporters are involved in auxin-mediated development in Arabidopsis thaliana

In Arabidopsis thaliana, the endosomal-localized Na+/H+ antiporters NHX5 and NHX6 regulate ion and pH homeostasis and are important for plant growth and development. However, the mechanism by which these endosomal NHXs function in plant development is not well understood. Auxin modulates plant growth and development through the formation of concentration gradients in plant tissue to control cell division and expansion. Here, we identified a role for NHX5 and NHX6 in the establishment and maintenance of auxin gradients in embryo and root tissues. We observed developmental impairment and abnormal cell division in embryo and root tissues in the double knockout nhx5 nhx6, consistent with these tissues showing high expression of NHX5 and NHX6. Through confocal microscopy imaging with the DR5:: GFP auxin reporter, we identify defects in the perception, accumulation and redistribution of auxin in nhx5 nhx6 cells. Furthermore, we find that the steady-state levels of the PIN-FORMED (PIN) auxin efflux carriers PIN1 and PIN2 are reduced in nhx5 nhx6 root cells. Our results demonstrate that NHX5 and NHX6 function in auxin-mediated plant development by maintaining PIN abundance at the plasma membrane, and provide new insight into the regulation of plant development by endosomal NHX antiporters

Estimating the ‘consumer surplus’ for branded versus standardised tobacco packaging

© 2016 BMJ Publishing Group. All rights reserved. Background: Tobacco companies question whether standardised (or ‘plain’) packaging will change smokers’ behaviour. We addressed this question by estimating how standardised packaging compared to a proven tobacco control intervention, price increases through excise taxes, thus providing a quantitative measure of standardised packaging’s likely effect. Methods: We conducted an online study of 311 New Zealand smokers aged 18 years and above that comprised a willingness-to-pay task comparing a branded and a standardised pack at four different price levels, and a choice experiment. The latter used an alternative-specific design, where the alternatives were a branded pack or a standardised pack, with warning theme and price varied for each pack. Results: Respondents had higher purchase likelihoods for the branded pack (with a 30% warning) than the standardised pack (with a 75% warning) at each price level tested, and, on average, were willing to pay approximately 5% more for a branded pack. The choice experiment produced a very similar estimate of ‘consumer surplus’ for a branded pack. However, the size of the ‘consumer surplus’ varied between warning themes and by respondents’ demographic characteristics. Conclusions: These two experiments suggest standardised packaging and larger warning labels could have a similar overall effect on adult New Zealand smokers as a 5% tobacco price increase. The findings provide further evidence for the efficacy of standardised packaging, which focuses primarily on reducing youth initiation, and suggest this measure will also bring notable benefits to adult smokers

Dissuasive cigarette sticks: The next step in standardised (‘plain’) packaging?

© 2016 BMJ Publishing Group. All rights reserved. Background: Standardised (or ‘plain’) packaging has reduced the appeal of smoking by removing imagery that smokers use to affiliate themselves with the brand they smoke. We examined whether changing the appearance of cigarette sticks could further denormalise smoking and enhance the negative impact of standardised packaging. Methods: We conducted an online study of 313 New Zealand smokers who comprised a Best-Worst Choice experiment and a rating task. The Best-Worst experiment used a 2×3×3×6 orthogonal design to test the following attributes: on-pack warning message, branding level, warning size and stick appearance. Results: We identified three segments whose members’ choice patterns were strongly influenced by the stick design, warning theme and size, and warning theme, respectively. Each of the dissuasive sticks tested was less preferred and rated as less appealing than the most common stick in use; a ‘minutes of life lost’ stick was the most aversive of the stimuli tested. Conclusions: Dissuasive sticks could enhance the effect of standardised packaging, particularly among older smokers who are often more heavily addicted and resistant to change. Countries introducing standardised packaging legislation should take the opportunity to denormalise the appearance of cigarette sticks, in addition to removing external tobacco branding from packs and increasing the warning size

Increasing follow-up questionnaire response rates in a randomized controlled trial of telehealth for depression: three embedded controlled studies

Background: Attrition is problematic in trials, and may be exacerbated in longer studies, telehealth trials and participants with depression – three features of The Healthlines Study. Advance notification, including a photograph and using action-oriented email subject lines might increase response rates, but require further investigation. We examined the effectiveness of these interventions in three embedded Healthlines studies. Methods: Based in different trial sites, participants with depression were alternately allocated to be pre-called or not ahead of the 8-month follow-up questionnaire (Study 1), randomized to receive a research team photograph or not with their 12-month questionnaire (Study 2), and randomized to receive an action-oriented (‘ACTION REQUIRED’) or standard (‘Questionnaire reminder’) 12-month email reminder (Study 3). Participants could complete online or postal questionnaires, and received up to five questionnaire reminders. The primary outcome was completion of the Patient Health Questionnaire (PHQ-9). Secondary outcome measures were the number of reminders and time to questionnaire completion. Results: Of a total of 609 Healthlines depression participants, 190, 251 and 231 participants were included in Studies 1–3 (intervention: 95, 126 and 115), respectively. Outcome completion was ≥90 % across studies, with no differences between trial arms (Study 1: OR 0.38, 95 % CI 0.07–2.10; Study 2: OR 0.84, 95 % CI 0.26–2.66; Study 3: OR 0.53 95 % CI 0.19–1.49). Pre-called participants were less likely to require a reminder (48.4 % vs 62.1 %, OR 0.41, 95 % CI 0.21–0.78), required fewer reminders (adjusted difference in means −0.67, 95 % CI −1.13 to −0.20), and completed follow-up quicker (median 8 vs 15 days, HR 1.35, 95 % CI 1.00–1.82) than control subjects. There were no significant between-group differences in Studies 2 or 3. Conclusions: Eventual response rates in this trial were high, with no further improvement from these interventions. While the photograph and email interventions were ineffective, pre-calling participants reduced time to completion. This strategy might be helpful when the timing of study completion is important. Researchers perceived a substantial benefit from the reduction in reminders with pre-calling, despite no overall decrease in net effort after accounting for pre-notification

Green competence framework: Evidence from China

© 2015 Taylor & Francis Recently human resources management functions such as recruitment, selection, training and performance evaluation are expected in considering environmental management issues. Environmental protective acts with adequate ecological knowledge and socio-economic behavior and skills are referred to in this paper as green competencies (GCs). However, a systematic approach for developing and understanding key factors that enhance individuals' GCs is lacking. This study contributes to green human resource literature by integrating environmental consumer behavior literature with traditional skills and competencies literature to help firms to select the right individuals to achieve their environmental goals. Using Robert's competencies framework and structural equation modeling, this paper empirically examines the influence of individual GCs on organizations' green practices and performance objectives. Our model is tested using a sample of 1230 employees working in key industries in the Chinese coastal city of Ningbo. The results indicate that acquired GCs are more positively associated with individuals' GCs and green behavior. The study empirically demonstrates that verifying acquired GC attributes such as environmental knowledge, green purchase attitude and intention during employee selection would certainly be helpful for firms to identify individual green performance potential

A look at the consumption behaviours along Ghana’s slave routes.

This study examines the consumption behaviours of four types of visitors to sites associated with the Transatlantic Slave Trade in Ghana. A questionnaire was used to elicit information regarding sites they intended or actually visited, perceived differences regarding site experiences and impressions of the heritage product itself. The results show that visitors were highly selective in their consumption patterns, although the sites in the country’s south were the major attractions and generators for all purposes. There is evidence that trip motive and connection to slavery influence consumption behaviour, as some visitors are willing to invest effort, expense and time to consume truly unique learning experiences. The findings were interpreted as evidence that site managers may need to design strategies using visitor profile and consumption patterns to deliver a coordinated and integrated appeal to the target visitor group

Any difference? Use of a CAM provider among cancer patients, coronary heart disease (CHD) patients and individuals with no cancer/CHD

<p>Abstract</p> <p>Background</p> <p>Although use of complementary and alternative medicine (CAM) among cancer patients has been described previously, prevalence of use has not commonly been compared to other disease groups in a true population sample where CAM use or cancer is not the main focus. The aims of the present study are to (1) examine how CAM use in cancer patients differs from people with a previous CHD diagnosis and people with no cancer or CHD diagnosis in an unselected general population and (2), investigate the use of a CAM provider among individuals with a previous cancer diagnosis.</p> <p>Methods</p> <p>A total of 8040 men and women aged 29 to 87 in the city of Tromsø, Norway filled in a questionnaire developed specifically for the Tromsø V study with questions on life style and health issues. Visits to a CAM provider within the last 12 months and information on cancer, heart attack and angina pectoris (heart cramp) were among the questions. 1449 respondents were excluded from the analyses.</p> <p>Results</p> <p>Among the 6591 analysed respondents 331 had a prior cancer diagnosis, of whom 7.9% reported to have seen a CAM provider within the last 12 months. This did not differ significantly from neither the CHD group (6.4%, p = 0.402) nor the no cancer/CHD group (9.5%, p = 0.325).</p> <p>Conclusion</p> <p>According to this study, the proportion of cancer patients seeing a CAM provider was not statistically significantly different from patients with CHD or individuals without cancer or CHD.</p
