“…All respondents in this study were high school graduates or higher, and 56.6% were college graduates. These results are consistent with previous research that showed that a higher education level precipitates higher consumer empowerment [48,53,54]. Although the Dunning−Kruger effect refers to the phenomenon in which people with low abilities overestimate their abilities, most studies applying the Dunning−Kruger effect also examine how people with high abilities underestimate their abilities [45].…”

“…As OG and EG had high self-assessment scores, the results suggest that self-assessment is higher among younger consumers. This finding is consistent with the results of a previous study on genetically modified food by Hwang and Nam, who reported that younger people rated their knowledge of genetically modified food higher [48]. However, although previous studies [17,48,55] reported the influence of education on consumer knowledge or consumer empowerment, the influence of educational level was not verified in this study.…”

“…This below-average group is also likely to rely on partisan source cues to evaluate the political knowledge of peers [47]. A study by Hwang and Nam further distinguished between objective and subjective knowledge and identified how an imbalance between the two influenced consumers' attitudes and purchase intentions toward genetically modified foods [48]. Various empirical studies have shown that individuals with low levels of competence will judge themselves to be more competent than they really are, whereas those with high levels of competence will underestimate their abilities; these studies emphasized the importance of self-assessment of consumer empowerment.…”

This study examined the influence of consumer empowerment and its self-assessment on consumers’ information search behavior and consumer life satisfaction; it also examined whether the results were consistent with the Dunning−Kruger effect. A total of 977 consumers who participated in a national consumer survey were divided into four groups, based on their level of empowerment and self-assessment. The Dunning−Kruger effect was observed in the consumer empowerment results, with 35.9% of respondents showing imbalanced empowerment and self-assessment levels. A general linear model was used to examine the survey results, which indicated that the main effect of empowerment had no significant effect on information searching or consumer life satisfaction. However, there was a significant main effect of self-assessment on both dependent variables. In addition, the interaction of empowerment and self-assessment had a significant effect only on information search behavior. Consequently, it can be concluded that self-assessed empowerment, rather than actual consumer empowerment, affects information search and consumer life satisfaction.

“…Obsah informácií priamo pôsobí na formovanie názorov, ktoré môžu byť pozitívne, ale aj negatívne (Connor & Siegrist, 2010). Mnohé štúdie (Hekmat & Dawson, 2019;Hwang & Nam, 2020;Popek & Halagarda, 2017;Rose et al, 2019) poukazujú na pozitívnu koreláciu medzi mierou informovanosti a vedomostí, a mierou akceptácie geneticky modifikovaných potravín. Existujú však aj štúdie, ktoré nezaznamenali signifikantne významný vzťah medzi mierou informovanosti a postojmi voči genetickej modifikácií (Klerck & Sweeney, 2007;Scholderer & Frewer, 2003) Ďalším dôležitým zdrojom informácií je pre spotrebiteľov značenie na obalochvýrobkov.…”

Zvládání zátěže v lidském životě je již dlouho častým předmětem intenzivního zájmu psychologů a dalších odborníků, stejně jako širší veřejnosti. Početné výzkumné výsledky, teorie, odborné i laické názory na tuto problematiku představují obsáhlou látku, v níž je velmi obtížné se uspokojivě orientovat. Příspěvek přináší přehled vybraných jevů a podstatných souvislostí v situacích, kdy jsou lidé vystaveni nárokům, jež je potřeba zvládnout. Zaměřuje se zejména na podstatu, terminologii a metodologické uchopení a závažné souvislosti adaptace člověka na zátěž, příslušných dispozičních předpokladů a na volbu způsobů zvládání zátěže spojené s životem jedince. Přitom přihlíží k limitním nárokům (stresorům), které svou intenzitou či trváním přesahují, případně dostatečně nevyužívají adaptační kapacitu jedince. Expozice takovým nárokům může pro jedince vyznívat v podstatě v subjektivním či objektivním smyslu negativně (ohrožení psychické rovnováhy, stavu organismu apod.) i pozitivně (zdroj rozvojových podnětů a příležitostí).

“…As a result of these studies, the diversity of GM crops has increased, and GM crops that meet the needs of consumers are continuously being developed in response to the rapidly changing climate change [9]. Nevertheless, citizens' anxiety about GM crops still exists, and it is urgent to establish environmental risk assessment standards and frame that can alleviate these concerns [10].…”

Background The drought environment occurs frequently due to the unpredictable future climate change, and drought has a direct negative impact on crops, such as yield reduction. Drought events are random, frequent, and persistent. Molecular breeding can be used to create drought-tolerant food crops, but the safety of genetically modified (GM) plants must be demonstrated before they can be adopted. In this research, the environmental risk of drought-tolerant GM rice was explored by assessing phenotype and gene flow. Drought resistance genes CaMsrB2 inserted HV8 and HV23 were used as GM rice to analyze the possibility of various agricultural traits and gene flow along with non-GM rice. Results When the traits 1000-grain weight, grain length/width, and yield, were compared with GM rice and non-GM rice, all agricultural traits of GM rice and non-GM rice were the same. In addition, when the germination rate, viviparous germination rate, pulling strength, and bending strength were compared to analyze the possibility of weediness, all characteristic values of GM rice and non-GM rice were the same. Protein, amylose, and moisture, the major nutritional elements of rice, were also the same. Conclusions The results of this research are that GM rice and non-GM rice were the same in all major agricultural traits except for the newly assigned characteristics, and no gene mobility occurred. Therefore, GM rice can be used as a means to solve the food problem in response to the unpredictable era of climate change in the future.
