Factors Influencing People’s Acceptance of Gene Technology: The Role of Knowledge, Health Expectations, Naturalness, and Social Trust:

This article aims to examine which factors influence people’s perception of gene technology. Data come from a mail survey in the German speaking part of Switzerland (N = 830). Principal component analyses for acceptance, risks, and benefits of 12 gene technology applications resulted in two factors: one related to medical applications and the other to nonmedical applications. Results showed that three different types of knowledge did not substantially influence perceived risks or perceived benefits of gene technology. Overall results suggest that the experiential system and not the analytical system determines lay people’s perception of gene technology.

The Power of Association: Its Impact on Willingness to Buy GM Food

ABSTRACT Affect, associations, and images associated with food technologies may be important factors influencing consumers’ perception of and willingness to accept new food technologies. The aim of the present study was to investigate free associations evoked by the term “biotechnology” and how they influence behavior. Therefore, participants (N = 632) were asked to name three associations they had in mind when confronted with the term “biotechnology.” After that, respondents indicated how positive or how negative these associations were. Additionally, an equivalent gain task was used to measure participants’ behavioral intentions related to genetically modified (GM) chocolate. Results of a log-linear analysis and a correspondence analysis suggest that attitudes toward biotechnology result in a wide range of associations. Participants having negative attitudes mentioned images related to the environment and industry more often compared with participants having positive attitudes. Results of the equivalent gain task show that willingness to buy GM chocolate can be predicted by the subjects’ three reported associations (p < .001), as well as by their gender (p = .003). The model explains 33.5% of the variance. Affect related to peoples associations with gene technology strongly influenced their acceptance of GM foods.

Impact of transgenic oilseed rape expressing oryzacystatin-1 (OC-1) and of insecticidal proteins on longevity and digestive enzymes of the solitary bee Osmia bicornis.

The risk that insect-resistant transgenic plants may pose for solitary bees was assessed by determining longevity of adult Osmia bicornis (O. rufa) chronically exposed to transgenic oilseed rape expressing oryzacystatin-1 (OC-1) or to the purified insecticidal proteins recombinant rOC-1, Kunitz soybean trypsin inhibitor (SBTI), Galanthus nivalis agglutinin (GNA), or Bacillus thuringiensis toxin Cry1Ab dissolved in sugar solution (at 0.01 and 0.1%, w:v, Cry1Ab only at 0.01%). Compared to control bees, longevity was significantly reduced by SBTI and GNA at both concentrations and by rOC-1 at 0.1%, but not by Cry1Ab or rOC-1 at 0.01%. Longevity on the OC-1 oilseed rape was not significantly different from the control plants. The effects of SBTI and rOC-1 on longevity were investigated through characterization of the digestive proteinases of O. bicornis and analysis of the response in proteinase profiles to ingestion of these proteinase inhibitors. A relatively complex profile of at least four types of soluble proteolytic enzymes was identified. Serine proteinases were found to be predominant, with metallo and especially cysteine proteinases making a smaller albeit significant contribution. The compensatory response to in vivo enzyme inhibition was similar for SBTI and rOC-1 although less pronounced for rOC-1. It consisted of a non-specific overproduction of native proteinases, both sensitive and insensitive, and the induction of a novel aspartic proteinase.

Sorting biotechnology applications: Results of multidimensional scaling (MDS) and cluster analysis

When people respond to questionnaires, they may construct preferences using various sources of information available, even questions within the questionnaire. An experimental approach with a representative sample of the Swiss population was applied to investigate how stable attitudes towards biotechnology are and which criteria people use spontaneously to evaluate and categorise biotechnology applications providing as little information as possible. A free card-sorting task using risk as a criterion versus not imposing a criterion was applied. Data were analysed using multidimensional scaling (MDS) and were represented in a cognitive map. Results of our experimental manipulation suggest that people’s preferences for biotechnology applications are relatively stable. Different sorting instructions did not result in different cognitive maps. Results suggest, therefore, that participants’ evaluations are not strongly influenced by criteria used in a questionnaire. The descriptions of the applications seem to be more crucial.

Public risk perception in the total meat supply chain

Due to past major food scares, food-safety perceptions have become a widely investigated topic. The aim of the present study was to examine food-safety perceptions separately for every step of the total meat supply chain, as such a detailed approach yields more promising strategies to ensure food safety in the future. Using a large-scale survey, we examined people’s risk perceptions of 18 steps describing the total meat supply chain. The results revealed a clear distinction between risk perception at the production stage and risk perception at home in the total meat supply chain, in that people perceived significantly less risk at home. However, people’s risk perceptions of the single stages in the total meat supply chain were overall slightly above average. Additionally, there were individual differences, as risk perception at the production stage was highly correlated with risk perception at home, meaning that some people perceived more risk than others overall. Using a multiple regression analysis, we found food-safety perceptions to be barely significant next to other important variables affecting people’s meat-consumption decisions. For those analyses, we asked participants to assess several constructs previously found to be associated with meat consumption. The goal was to determine how food-safety perceptions influence people’s meat consumption next to other important constructs in situations in which no major food scandal is present. The present paper concludes by discussing possible marketing and policy strategies to overcome people’s inaccurate safety perceptions of the stages of the total food chain.

The stability of risk and benefit perceptions: a longitudinal study assessing the perception of biotechnology

The study of public perceptions is considered to be important for making sound policy decisions, since the public decides which products will enter and sustain in the market. Stability of public perceptions is important for policy-makers; only if public attitudes and perceptions remain constant, policy-makers will be able to take them into account. The aim of the present study was to examine the stability of participants’ risk and benefit perceptions of gene technology over a period of two years. In spring, 2008 and in spring, 2010, the same sample of participants filled out an identical questionnaire. Results of structural equation modelling show that risk and benefit perceptions of gene technology applications are moderately stable (r = .5–.7). Furthermore, results show that people distinguish between medical, plant and food applications and applications involving animals when evaluating the risk of gene technology. When evaluating the benefits, participants also take consumer-related benefits into account, such as enhancement of functional properties. Results of the present study suggest that risk research should regularly examine people’s risk perceptions in order to gain a clearer picture of the dynamics of people’s perception and preferences not only of novel technologies, but also of entrenched technologies.

Quality of life and adolescents’ communication with their significant others (mother, father, and best friend): the mediating effect of attachment to pets

ABSTRACT The relationship between adolescents’ communication with their significant others (mother, father, and best friend) and quality of life (KIDSCREEN) was investigated in 2262 Scottish adolescent pet owners. The variable attachment to pets was also tested and assessed as a mediator of this relationship. A positive relationship between adolescents’ communication with their significant other (mother, father, and best friend) and quality of life decreased when controlling for attachment to dogs. In cat owners, a positive relationship between communication with a best friend and quality of life decreased when controlling for attachment to cats. In cat and dog owners, attachment to these pets predicted higher levels of quality of life. Higher attachment to dogs and cats was explained by good best friend (IV) and attachment to pets (DV) and best friends. Mediation effects of attachment to dogs and cats might be explained in terms of the caring activities associated with these types of pets.

Educating the patient for health care communication in the age of the world wide web: a qualitative study.

Purpose Communication skills teaching in medical education has yet to acknowledge the impact of the Internet on physician–patient communication. The authors present a conceptual model showing the variables influencing how and to what extent physicians and patients discuss Internet-sourced health information as part of the consultation with the purpose of educating the patient. Method A study exploring the role physicians play in patient education mediated through health information available on the Internet provided the foundation for the conceptual model. Twenty-one physicians participated in semistructured interviews between 2011 and 2013. Participants were from Australia and Switzerland, whose citizens demonstrate different degrees of Internet usage and who differ culturally and ethnically. The authors analyzed the interviews thematically and iteratively. The themes as well as their interrelationships informed the components of the conceptual model. Results The intrinsic elements of the conceptual model are the physician, the patient, and Internet based health information. The extrinsic variables of setting, time, and communication activities as well as the quality, availability, and usability of the Internet-based health information influenced the degree to which physicians engaged with, and were engaged by, their patients about Internet-based health information. Conclusions The empirically informed model provides a means of understanding the environment, enablers, and constraints of discussing Internet-based health information, as well as the benefits for patients’ understanding of their health. It also provides medical educators with a conceptual tool to engage and support physicians in their activities of communicating health information to patients.

Sociodemographics of Pet Ownership among Adolescents in Great Britain: Findings from the HBSC Study in England, Scotland, and Wales

ABSTRACT The aim of this study was to assess the prevalence of pet ownership among adolescents in Great Britain and identify any sociodemographic differences between pet owners and non-pet owners. A total of 14,328 11-to 15-year-old adolescents from England, Scotland, and Wales were included in the analysis. Results revealed 15-year-old adolescents were significantly more likely than 11-year-old adolescents to own dogs (OR = 1.146, p < 0.001) but less likely to own fish, reptiles, or amphibians (OR = 0.629, p < 0.001), and small mammals (OR = 0.630, p < 0.001). Thirteen-year-olds were significantly more likely than 11-year-olds to own dogs (OR = 1.240, p = 0.021) and birds (OR = 1.299, p = 0.010), but significantly less likely to own fish, reptiles, or amphibians (OR = 0.795, p < 0.001). No gender differences were found. White adolescents were more likely than non-white adolescents to own all pet types. Those living in single-parent families were significantly more likely than those living with two parents to own dogs (OR = 1.186, p = 0.013) and cats (OR = 1.319, p < 0.001). Furthermore, those who reported living in stepfamilies were also more likely to own cats (OR = 1.428, p < 0.001). Adolescents with siblings were more likely to own cats (OR = 1.391, p = 0.001), fish, reptiles, or amphibians (OR = 1.220, p = 0.037) than adolescents without siblings. Adolescents with employed parents (both or one) were significantly more likely than those with unemployed parents to own dogs (OR = 1.414, p = 0.002) and birds (OR = 1.523, p = 0.018). Adolescents from high-affluence families were less likely than adolescents from low-affluence families to own dogs (OR = 0.888, p = 0.037), small mammals (OR = 0.832, p = 0.005), and birds (OR = 0.801, p = 0.046). Furthermore, family affluence differences were found in different pet types. Differences in all pet types and siblings were also found in a proxy measure of attachment to pets. This study provides evidence that pet ownership is related to several sociodemographic factors. These are relevant to take into account when performing HAI studies on adolescents.

Associations between oxytocin receptor gene polymorphisms, empathy towards animals and implicit associations towards animals

Simple Summary Oxytocin is a hormone which acts as a neurotransmitter has been associated with a wide range of human social behaviours. Single nucleotide polymorphisms (SNPs) within the oxytocin receptor gene (OXTR) have been described to be involved with human-human empathy, however little is known about OXTR SNPs and human-animal empathy and spontaneous reactions towards animals. This has been investigated in the present study with 161 British students and five extensively studied OXTR SNPs. Validated, standardized measures for empathy towards animals and spontaneous reactions towards animals have been employed. Results indicate that females show higher levels of empathy and have more positive reactions towards animals than males. Furthermore, empathy towards animals was associated with the absence of the minor A allele on OXTR SNP rs2254298. These results indicate that OXTRs play a role not only for human social behaviours but also for human-animal interactions. Abstract Oxytocin has been well researched in association with psychological variables and is widely accepted as a key modulator of human social behaviour. Previous work indicates involvement of oxytocin receptor gene (OXTR) single nucleotide polymorphisms (SNPs) in human-human empathy, however little is known about associations of OXTR SNPs with empathy and affective reactions of humans towards animals. Five OXTR SNPs previously found to associate with human social behaviour were genotyped in 161 students. Empathy towards animals and implicit associations were evaluated. A General Linear Model was used to investigate the OXTR alleles and allelic combinations along with socio-demographic variables and their influence on empathy towards animals. Empathy towards animals showed a significant association with OXTR SNP rs2254298; homozygous G individuals reported higher levels of empathy towards animals than heterozygous (GA). Our preliminary findings show, for the first time, that between allelic variation in OXTR and animal directed empathy in humans maybe associated, suggesting that OXTRs social behaviour role crosses species boundaries, warranting independent replication.
