Lisansüstü tezlerde bilgisayar destekli matematik öğretimi uygulamaları: meta-sentez çalışması

Endorsers are highly effective in promoting customer–brand engagement. New endorsers are emerging owing to the digital explosion. Who promotes brands better - mega or macro-influencers? Traditional celebrities can represent both types of endorsers (mega and macro) with a strong online presence but varying numbers of followers. This study conducted an online survey to determine the antecedents and consequences of endorsers' participation in marketing and communication strategies. The results of path analysis showed that brand and endorser credibility played a significant role in determining customer brand engagement and brand equity. Endorser credibility impacted brand equity only in the case of mega-influencers. Smaller influencers exhibited higher prowess than celebrities to engage customers, thus suggesting that “less is more.” 

Mega or macro social media influencers: Who endorses brands better?


Purpose
Although competitor orientation (CO) has been given great attention, its link to firm performance (FP) is still unclear. The reason behind this may be attributed to the fact that the CO–FP relationship depends on several contingencies. The purpose of this paper is to simultaneously explore the separate and combined moderating effects of marketing ethics (ME) and competitive intensity (CI) in the CO–FP relationship.


Design/methodology/approach
The participants in this study were managers or owners from 289 manufacturing SMEs located in two regions in Yemen (i.e. Sana’a and Taiz). Hierarchical regression analysis using PROCESS Macro V. 3.5 in SPSS was performed to analyze the data collected.


Findings
The obtained results reveal that ME in fact positively moderates the CO–FP relationship and, importantly, this effect is not influenced by CI.


Practical implications
The findings of this paper provide advantageous insights for managers and decision-makers for SMEs as it is expected that they demonstrate a greater commitment to the practice of ME in their firms. This has implications that with the practice of ME, it is expected that SMEs will be able to use the full potential of CO to improve their performance at a low level of CI.


Originality/value
This study contributes to widening the studies on CO, ME, CI and SMEs in a different context. In addition, it adds to the knowledge by exploring the combined moderating influence of internal (e.g. ME) and external factors (e.g. CI) when examining the CO–FP relationship.


Competitor orientation and SME performance in competitive environments: the moderating effect of marketing ethics

This study aims to examine the influence of five sports celebrity personality (SCP) attributes – attractiveness, expertise level, credibility, trustworthiness and character – on consumers' purchase intentions (CPI). It identifies celebrity brand congruence (CBC), endorsed brand celebrity (EBC) and transfer of brand image (TBI) as antecedents of CPI.,The purposive sampling technique was used to collect the data from 838 respondents. This study developed a multidimensional construct for SCP. The covariance-based structural equation modeling (SEM) technique was used to examine the relationship between SCP and the endorsed brand. The study used CBC as a mediator and EBC and TBI as partial mediators. The direct and indirect effect of SCP on CPI was investigated using CBC, EBC and TBI as mediators.,This study supports the importance of three antecedents (i.e. CBC, EBC and TBI) on CPI. It finds congruence across SCP and CBC variables, and a positive impact of SCP on EBC and TBI variables. Also, it exhibits a significant direct effect of CBC on EBC and TBI, whereas the direct effect of CBC on CPI is not substantial. The indirect effect of CBC through mediating variables EBC and TBI found to be significant.,This study concludes that sports celebrity endorsement is essential to transfer the positive celebrity image to the endorsed brand image. However, it is not merely sufficient to influence the buyers' purchase conduct; the brand credibility additionally assumes to take a role in changing their behavioral intentions.,This study contributes to the sports marketing literature by its novelty in analyzing the sports celebrity personality at a multidimensional level. It uses SCP's different attributes as one construct and studies its impact on CPI by taking CBC, EBC and TBI as mediators. The results of this study equip sports management professionals with the knowledge to build better long-term relationships with consumers.

The present research aims to investigate the effects of DEE (di-ethyl ether) on diesel and Rice Bran biodiesel blends with biogas induction on the performance and emissions of the dual-fuel diesel engine. Two fuel blends are used denoted as D80–B10–DEE10 (80% diesel, 10% biodiesel and 10% diethyl ether) and D60–B20–DEE20 (60% diesel, 20% biodiesel and 20% diethyl ether). The biodiesel was prepared through the use of the transesterification process from Rice Bran oil. As pilot fuel, blends of diesel–Rice Bran biodiesel and DEE were used in the engine operation, and biogas was taken as a primary (gaseous) fuel. Biogas was inducted into the engine with a flow rate of 0.9 kg/h through the intake manifold. The findings show that D80–B10–DEE10 blend produced a 2.61% increase in BTE and a 5.23% decrease in BSFC compared to D60–B20–DEE20 at full load, respectively. In comparison to diesel, a reduction in CO emissions of around 9.4% and 12.3% were observed for blend D80–B10–DEE10 and blend D60–B20–DEE20 at full load, respectively. HC emissions for the D80–B10–DEE10 and D60–B20–DEE20 were also reduced at full load, by 7.1% and 10.8%, respectively, as compared to diesel. Results have thus shown that DEE has a sound effect on the engine with the induction of biogas.
