As the annual production of the solid waste generable in the form of spent coffee bean powder (SCBP) is over 6 million tons, its utilization in the generation of green energy, waste water treatment and as a filler in biocomposites is desirable. The objective of this article is to analyze the possibilities to valorize coffee bean powder as a filler in cellulose matrix. Cellulose matrix was dissolved in the relatively safer aqueous solution mixture (8% LiOH and 15% Urea) precooled to -12.5°C. To the cellulose solution (SCBP) was added in 5-25wt% and the composite films were prepared by regeneration method using ethyl alcohol as a coagulant. Some SCBP was treated with aq. 5% NaOH and the composite films were also prepared using alkali treated SCBP as a filler. The films of composites were uniform with brown in color. The cellulose/SCBP films without and with alkali treated SCBP were characterized by FTIR, XRD, optical and polarized optical microscopy, thermogravimetric analysis (TGA) and tensile tests. The maximum tensile strength of the composite films with alkali treated SCBP varied between (106-149MPa) and increased with SCBP content when compared to the composites with untreated SCBP. The thermal stability of the composite was higher at elevated temperatures when alkali treated SCBP was used. Based on the improved tensile properties and photo resistivity, the cellulose/SCBP composite films with alkali treated SCBP may be considered for packaging and wrapping of flowers and vegetables.
Consumer psychology has been proven to have an essential influence on aesthetic preferences. Previous research on aesthetics focused on long-lasting product categories and was conducted at a single level. However, aesthetics is multidimensional, which has been overlooked. Our research is based on the unified model of aesthetics (UMA), which aims to investigate the unique contributions of the perceptual (unity, variety), cognitive (typicality, novelty), and social (connectedness, autonomy) levels to aesthetic preferences for packaging designs. The studies used soft drink packaging from the fast-moving consumer goods (FMCG) category as stimuli, and Chinese participants evaluated the packaging on a 7-point Likert scale. Study 1 shows that people gravitate toward safety over accomplishment and that connectedness, typicality, and unity are the main determinants of aesthetic pleasure. Study 2 added two scenarios: for "going to a very formal meeting," stimuli with unity, typicality, and connectedness could best induce aesthetic pleasure. For "going to a good friend's rave party," the novelty, autonomy, and variety of designs were the most pleasing. Furthermore, two studies showed that for the overall stimulus, unity consistently evoked more positive aesthetic preferences than variety. Overall, this research provides new insights into aesthetic influences at the perceptual, cognitive, and social levels in soft drink packaging and offers new perspectives on aesthetic preferences for new product development.
OBJECTIVE: To review evidence on the impact of health warning messages on tobacco packages.
DATA SOURCES: Articles were identified through electronic databases of published articles, as well as relevant 'grey' literature using the following keywords: health warning, health message, health communication, label and labelling in conjunction with at least one of the following terms: smoking, tobacco, cigarette, product, package and pack.
STUDY SELECTION AND DATA EXTRACTION: Relevant articles available prior to January 2011 were screened for six methodological criteria. A total of 94 original original articles met inclusion criteria, including 72 quantitative studies, 16 qualitative studies, 5 studies with both qualitative and qualitative components, and 1 review paper: Canada (n=35), USA (n=29) Australia (n=16), UK (n=13), The Netherlands (n=3), France (n=3), New Zealand (n=3), Mexico (n=3), Brazil (n=2), Belgium (n=1), other European countries (n=10), Norway (n=1), Malaysia (n=1) and China (n=1).
RESULTS: The evidence indicates that the impact of health warnings depends upon their size and
DESIGN: whereas obscure text-only warnings appear to have little impact, prominent health warnings on the face of packages serve as a prominent source of health information for smokers and non-smokers, can increase health knowledge and perceptions of risk and can promote smoking cessation. The evidence also indicates that comprehensive warnings are effective among youth and may help to prevent smoking initiation. Pictorial health warnings that elicit strong emotional reactions are significantly more effective.
CONCLUSIONS: Health warnings on packages are among the most direct and prominent means of communicating with smokers. Larger warnings with pictures are significantly more effective than smaller, text-only messages.
