Does culture influence how consumers process negative celebrity information? Impact of culture in evaluation of negative celebrity information     

Nam-Hyun Um  Wei-Na Lee 《亚洲交流杂志》2015,25(3):327-347

This study investigates the relationship between cultural orientation (individualistic or collectivistic culture) and consumers' attribution styles (dispositional and situational attributions) as well as the consequences of attribution styles on brand evaluation and purchase intention. The study also examines how people perceive different types of negative celebrity information (self-oriented and other-oriented negative information) and how their identification with a celebrity endorser affects their response to negative information. The findings suggest that culture influences how consumers – having been exposed to negative celebrity information – make attributions. Dispositional attributions lead to more negative brand evaluation as well as to negative purchase intention. Other-oriented negative information leads to, among Korean consumers, more negative brand evaluation. Finally, the study found that consumers highly identified with a celebrity endorser are less likely to be influenced by negative celebrity information.  相似文献   

Predicting Parent-Child Differences in Perceptions of How Children Use the Internet for Help With Homework,Identity Development,and Health Information     

Sherri Jean Katz  Theodore Lee  Sahara Byrne 《广播与电子媒介杂志》2015,59(4):574-602

Bioecological systems theory provides a framework to understand how factors in the child's environment contribute to parent-child differences in estimations of how often children are helped by their Internet use. A national sample survey of 456 matched parent-child pairs investigated how parents-child relational factors, parental attitudes toward the Internet, and the bio-ecology of the child, are related to differing perceptions of the frequency of using the Internet to seek help with homework assignments, to aid in identity development, and to find health information. While previous research shows that parents underestimate risky online behaviors, we investigate whether parent-child differences will emerge in regards to how often the child engages in the behaviors under investigation here. The findings show that parents overestimate these online activities, suggesting they are biased in their estimations. Parent-child relational factors emerged as predictors of parental overestimation for each of these online activities, with trust perceptions as the most consistent predictor. Parental attitudes toward the Internet predicted parent-child differences in perceptions of how frequently the child used the Internet for help with homework and identity development, while the bioecology of the child was only predictive in the case of using the Internet for help with homework.  相似文献   

Structural design of a double-layered porous hydrogel for effective mass transport     

Hyejeong Kim  Hyeon Jeong Kim  Hyung Kyu Huh  Hyung Ju Hwang  Sang Joon Lee 《Biomicrofluidics》2015,9(2)

Mass transport in porous materials is universal in nature, and its worth attracts great attention in many engineering applications. Plant leaves, which work as natural hydraulic pumps for water uptake, have evolved to have the morphological structure for fast water transport to compensate large water loss by leaf transpiration. In this study, we tried to deduce the advantageous structural features of plant leaves for practical applications. Inspired by the tissue organization of the hydraulic pathways in plant leaves, analogous double-layered porous models were fabricated using agarose hydrogel. Solute transport through the hydrogel models with different thickness ratios of the two layers was experimentally observed. In addition, numerical simulation and theoretical analysis were carried out with varying porosity and thickness ratio to investigate the effect of structural factors on mass transport ability. A simple parametric study was also conducted to examine unveiled relations between structural factors. As a result, the porosity and thickness ratio of the two layers are found to govern the mass transport ability in double-layered porous materials. The hydrogel models with widely dispersed pores at a fixed porosity, i.e., close to a homogeneously porous structure, are mostly turned out to exhibit fast mass transport. The present results would provide a new framework for fundamental design of various porous structures for effective mass transport.  相似文献   

Effects of hydraulic pressure on cardiomyoblasts in a microfluidic device     

Yu-Fang Hsiao  Huei-Jyuan Pan  Yi-Chung Tung  Chien-Chang Chen  Chau-Hwang Lee 《Biomicrofluidics》2015,9(2)

We employed a microfluidic device to study the effects of hydraulic pressure on cardiomyoblast H9c2. The 170 mm Hg pressure increased the cellular area and the expression of atrial natriuretic peptide. With the same device, we demonstrated that the effects of hydraulic pressure on the cardiomyoblast could be reduced by the inhibitor of focal adhesion kinase. This mechanical–chemical antagonism could lead to a potential therapeutic strategy of hypertension-induced cardiac hypertrophy.  相似文献   

An integrated microfluidic system for screening of phage-displayed peptides specific to colon cancer cells and colon cancer stem cells     

Yu-Jui Che  Huei-Wen Wu  Lien-Yu Hung  Ching-Ann Liu  Hwan-You Chang  Kuan Wang  Gwo-Bin Lee 《Biomicrofluidics》2015,9(5)

Affinity reagents recognizing biomarkers specifically are essential components of clinical diagnostics and target therapeutics. However, conventional methods for screening of these reagents often have drawbacks such as large reagent consumption, the labor-intensive or time-consuming procedures, and the involvement of bulky or expensive equipment. Alternatively, microfluidic platforms could potentially automate the screening process within a shorter period of time and reduce reagent and sample consumption dramatically. It has been demonstrated recently that a subpopulation of tumor cells known as cancer stem cells possess high drug resistance and proliferation potential and are regarded as the main cause of metastasis. Therefore, a peptide that recognizes cancer stem cells and differentiates them from other cancer cells will be extremely useful in early diagnosis and target therapy. This study utilized M13 phage display technology to identify peptides that bind, respectively, to colon cancer cells and colon cancer stem cells using an integrated microfluidic system. In addition to positive selection, a negative selection process was integrated on the chip to achieve the selection of peptides of high affinity and specificity. We successfully screened three peptides specific to colon cancer cells and colon cancer stem cells, namely, HOLC-1, HOLC-2, and COLC-1, respectively, and their specificity was measured by the capture rate between target, control, and other cell lines. The capture rates are 43.40 ± 7.23%, 45.16 ± 7.12%, and 49.79 ± 5.34% for colon cancer cells and colon cancer stem cells, respectively, showing a higher specificity on target cells than on control and other cell lines. The developed technique may be promising for early diagnosis of cancer cells and target therapeutics.  相似文献   

How liberals and conservatives respond to feasibility and desirability appeals in anti-tobacco campaigns     

Younghwa Lee  Sukki Yoon  Seungwoo Chun  Chanmo Park  Kacy Kim 《亚洲交流杂志》2019,29(1):55-72

Using two experiments, this study aims to investigate how politically liberal or conservative message recipients respond to anti-tobacco appeals. The results show that in Study 1, respondents were exposed to a message about price policy. In Study 2, they were exposed to a message about a warning policy. In both studies, liberal participants more favorably evaluated anti-tobacco messages emphasizing feasibility rather than desirability, whereas conservative participants more positively evaluated messages emphasizing desirability rather than feasibility. Implications for policymakers and marketers are discussed.  相似文献   

Helping Taiwanese Graduate Students Help Themselves: Applying Corpora to Industrial Management English as a Foreign Language Academic Reading and Writing     

Barry Lee Reynolds 《学校用计算机》2015,32(3-4):300-317

Lack of knowledge in the conventional use of vocabulary and multiword patterns in one's respective field of expertise causes Taiwanese students to produce academic writing that is markedly “non-nativelike.” This is because Taiwanese students are first and foremost second language readers and often have difficulty “picking up on” the regularly encountered language patterns found in scholarly texts. As one step in determining a solution to this problem, this article reports on a pilot implementation encouraging graduate Taiwanese students for whom English is a foreign language to use self-editing techniques in their own field-specific academic writing by use of a corpus tool. Classroom interviews, draft comparisons, and individual stimulated recall interviews showed a difference in acceptance and success after using the corpus tool (StringNet Navigator) as an aid to self-editing academic English writing. The corpus tool's functions, results of its use by industrial management graduate students for self-editing academic writing, and pedagogical implications are described.  相似文献

“What would you like me to do? Lie to you?” Teacher education responsibilities to LGBTI students     

Debora Lee  Vicki M. Carpenter 《Asia-Pacific Journal of Teacher Education》2015,43(2):169-180

The experiences of lesbian, gay, trans (The use of trans with an asterisk avoids the use of transsexual or transgender and promotes recognition of the inadequacy of such labels), bisexual and intersex (LGBTI) student teachers were recently investigated at a New Zealand faculty of education. Student teachers studying in early childhood education and care, primary and secondary initial teacher education (ITE) were asked about their perceptions of LGBTI visibility and inclusion. Methods used were online questionnaires, focus groups and individual interviews. While the study encompassed all aspects of the ITE programme, this work uses one specific question about practicum from the questionnaire, and findings related to practicum and teaching from the focus groups and individual interviews. In this article, the experiences of LGBTI (those who identified as non-heterosexual) student teachers and “straight” (those who identified as heterosexual) are discussed. Findings suggest that both faculty and practicum settings are heteronormative and indicate that LGBTI student teachers felt uncertain about their safety. Both LGBTI and straight students felt they had not been given adequate preparation to manage the complexities of diverse sexualities on practicum or in their future teaching. We argue that addressing heteronormativity in ITE will better prepare student teachers for the rich diversity of students and families they will encounter in their teaching.  相似文献
