Cross-cultural advertising : cultural values that affect advertising likeability

This paper attempts to investigate the cultural values that have influences on consumers’ advertising likeability. Three groups of nationalities were assessed, including: Singaporean Chinese, Chinese from China, and Westerners. Advertising likeability was examined from two aspects: liking of culturally congruent advertisements and liking of humorous advertisements with sexual content. In the analysis of the impact of cultural elements, individual-level factors that have potential moderating effects were taken into account. These consist of the need for cognition (NFC), need for humor (NFH), and cosmopolitanism (COS). The findings from this study have shown the effects of ad-culture congruency. In other words, cultural differences along Hofstede’s dimension of collectivism and individualism have effects on consumers’ preferences towards ad appeals. Subjects tend to show preferences for the ad appeal that is conforming to their cultural orientations. Specifically, Singaporean Chinese favor collectivistic themes, while their Western counterparts prefer individualistic themes. The moderating effect of Product type was not proved to be significant in this study. That is to say, whether the product is personal or non-personal, ad-culture congruency is beneficial. Besides, the level of cosmopolitanism did not appear to affect the liking of culturally congruent ads. With regards to humorous advertisements with sexual content, results from this study suggest that Singaporean Chinese favor those ads less than Westerners but more than Chinese from China. Being well-known as modern and open-minded, Singaporean Chinese are still conservative towards sexuality contents in humorous ads. This liking is moderated by the individual level of cosmopolitanism (COS) and need for humor (NFH). Specifically, people who are highly cosmopolitan and have higher need for humor shown greater liking for sexually humorous advertisements. Finally, the study looks at the role of advertising liking in advertising effectiveness. Findings have shown that liking of the ad leads to better attitudes towards the brand and purchase intention. This effect, however, is moderated by individual need for cognition (NFC)

Optimization of Superplastic Forming Process of AA7075 Alloy for the Best Wall Thickness Distribution

This work aims to optimize the process parameters for improving the wall thickness distribution of the sheet superplastic forming process of AA7075 alloy. The considered factors include forming pressure p (MPa), deformation temperature T (°C), and forming time t (minutes), while the responses are the thinning degree of the wall thickness ε (%) and the relative height of the product h*. First, a series of experiments are conducted in conjunction with response surface method (RSM) to render the relationship between inputs and outputs. Subsequently, an analysis of variance (ANOVA) is conducted to verify the response significance and parameter effects. Finally, a numerical optimization algorithm is used to determine the best forming conditions. The results indicate that the thinning degree of 13.121% is achieved at the forming pressure of 0.7 MPa, the deformation temperature of 500°C, and the forming time of 31 minutes

Measuring the Effectiveness of Vietnam’s National Action Plan to Increase Helmet Use among Child Motorcycle Passengers in Three Major Cities.

Motorcyclists account for 75% of the estimated 22,000 fatalities caused by road injury each year in Vietnam. Helmets, widely worn by adult motorcyclists, are a cost-effective and proven intervention. Despite legislation mandating that children 6 years and above must wear helmets, child helmet use rates in Vietnam were low. In response, AIP Foundation leveraged evidence from its previous communications campaign to advocate Vietnam’s National Traffic Safety Committee (NTSC) to issue a National Child Helmet Action Plan for all 63 provinces during 2015. As part of the action plan, AIP Foundation adapted and expanded its communications campaign design from three target cities (Hanoi, Ho Chi Minh City, and Danang) to nationwide, focusing on 12 other provinces in Vietnam. The objective of this study was to evaluate the progress of the action plan toward its aim to a transformational increase in child helmet use in the 15 target cities and provinces by the end of 2015. Helmet observations at systematically sampled schools in the target provinces before and after the first phase of the action plan. The results from the final evaluation of the previous communications campaign are serving as the baseline for three target cities and post-observations will take place in April and November 2015. AIP Foundation measured baselines at the remaining 12 target provinces in March 2015 and will conduct a post-observation in November 2015. If funding is available, an additional post-observation will take place in all 15 target cities/provinces in November 2016 to assess the sustainability of the action plan. Average helmet wearing rates increased from 38% across the three target cities in March 2014 to 69% in April 2015. Hanoi experienced the greatest increase: from 23% in 2014 to 69% in 2015. In Danang, child helmet use increased from 37% to 75%, and in Ho Chi Minh City, the rate increased from 48% to 68%. An integrated campaign with national government leadership can bring about a substantial change in child helmet use. The adaptations applied to the action plan implementation have had a greater effect than the previous communications campaign

Influence of biofertilizer produced using drumstick (Moringa oleifera L.) unused parts on the growth performance of two leafy vegetables

The non-edible parts of Moringa oleifera, such as stems, branches or leaf petioles, have often been discarded while the leaves are consumed as a vegetable or are used to produce organic fertilizer. This study aimed to determine the optimal conditions for producing Moringa organic fertilizer (MOF) from previously unused parts and to compare these fertilizers with cow manure and bio-organic fertilizer. Seventy kilograms of the unused Moringa parts were blended with fifty kilograms of manure, 0.2 kilogram of Trichoderma-based product and two kilograms of superphosphate. The mixture was incubated at different intervals, including 5, 7 or 9 weeks. Next, the effects of MOF on the growth, yield, ascorbic acid content and Brix of lettuce and mustard spinach were also determined and compared with other organic fertilizers (cow manure and bio-organic fertilizer). Results of the study revealed that 25 tons per ha of MOF were significantly superior to those treated with cow manure and bio-organic fertilizer in the case of vegetable yields. Further, 7 weeks of MOF incubation was found suitable to produce an optimal yield during the various incubation period. These results suggested that the Moringa non-edible parts can make organic fertilizer and enhance growth, yield, and leafy vegetable production

Selecting target market by similar measures in interval intuitionistic fuzzy set

The selection of the target market plays vital role in promoting the marketing strategies of companies. We presented is a method for target market selection. We introduce some novel similarity measures between intuitionistic fuzzy sets and the novel similarity measures between interval-valued intuitionistic fuzzy sets. They are constructed by combining exponential and other functions. Finally, we introduce a multi-criteria decision making model to select target market by using the novel similarity measure of interval intuitionistic fuzzy sets

Structural and Optoelectronic Properties of CdSe Tetrapod Nanocrystals for Bulk Heterojunction Solar Cell Applications

Semiconducting CdSe tetrapod nanoparticles were prepared, and their structural and optical properties were examined. The surface capping molecule, octylphosphonic acid, was replaced with butylamine after the particle synthesis. The exchange of surface ligands changed the physical properties of the nanocrystals, which resulted in a slight decrease in the nanoparticles size. The effects of changing surface ligands of CdSe tetrapod nanocrystals on the structural and optoelectronic properties were investigated, and it was found that the surfactant of nanoparticles could affect the device performance by enhancing the charge carrier separation at the active layer interfaces. Power conversion efficiency of the bulk heterojunction solar cells having the structure of glass/ITO/PEDOT:PSS/(CdSe + PCPDTBT)/Al was improved from 1.21% to 1.52% with the use of ligand-exchanged nanoparticles

Vietnamese version of the general medication adherence scale (Gmas):Translation, adaptation, and validation

Background: We aimed to translate, cross-culturally adapt, and validate the General Medication Adherence Scale (GMAS) into Vietnamese. Methods: We followed the guidelines of Beaton et al. during the translation and adaptation process. In Stage I, two translators translated the GMAS to Vietnamese. Stage II involved synthesizing the two translations. Stage III featured a back translation. Stage IV included an expert committee review and the creation of the pre-final version of the GMAS, and in stage V, pilot testing was conducted on 42 Vietnamese patients with type 2 diabetes. The psychometric validation process evaluated the reliability and validity of the questionnaire. The in-ternal consistency and test–retest reliability were assessed by Cronbach’s alpha and Spearman’s correlation coefficients. The construct validity was determined by an association examination between the levels of adherence and patient characteristics. The content validity was based on the opinion and assessment score by the expert committee. The Vietnamese version of the GMAS was created, in-cluding 11 items divided into three domains. There was a good equivalence between the English and the Vietnamese versions of the GMAS in all four criteria. Results: One hundred and seventy-seven patients were participating in the psychometric validation process. Cronbach’s alpha was acceptable for all questionnaire items (0.817). Spearman’s correlation coefficient of the test–retest reliability was acceptable for the GMAS (0.879). There are significant correlations between medication adherence levels and occupation, income, and the Beliefs about Medicines Questionnaire (BMQ) score regarding construct validity. Conclusions: The Vietnamese version of GMAS can be considered a reliable and valid tool for assessing medication adherence in Vietnamese patients
