Attitudes - Food choice motives - Food Choices Questionnaire - Food4Me - Intention - Nutrigenomics - Personalised nutrition - Survey
Objective: The present study explored associations between food choice motives, attitudes towards and intention to adopt personalised nutrition, to inform communication strategies based on consumer priorities and concerns. Design/Setting: A survey was administered online which included the Food Choice Questionnaire (FCQ) and items assessing attitudes towards and intention to adopt personalised nutrition. Subjects: Nationally representative samples were recruited in nine EU countries (n 9381). Results: Structural equation modelling indicated that the food choice motives ‘weight control’, ‘mood’, ‘health’ and ‘ethical concern’ had a positive association and ‘price’ had a negative association with attitude towards, and intention to adopt, personalised nutrition. ‘Health’ was positively associated and ‘familiarity’ negatively associated with attitude towards personalised nutrition. The effects of ‘weight control’, ‘ethical concern’, ‘mood’ and ‘price’ on intention to adopt personalised nutrition were partially mediated by attitude. The effects of ‘health’ and ‘familiarity’ were fully mediated by attitude. ‘Sensory appeal’ was negatively and directly associated with intention to adopt personalised nutrition. Conclusions: Personalised nutrition providers may benefit from taking into consideration the importance of underlying determinants of food choice in potential users, particularly weight control, mood and price, when promoting services and in tailoring communications that are motivationally relevant.

Automated testing - Multivocal literature mapping - Software testing - Survey - Systematic mapping - Test anti-patterns - Test automation - Test scripts - Test smells
As a type of anti-pattern, test smells are defined as poorly designed tests and their presence may negatively affect the quality of test suites and production code. Test smells are the subject of active discussions among practitioners and researchers, and various guidelines to handle smells are constantly offered for smell prevention, smell detection, and smell correction. Since there is a vast grey literature as well as a large body of research studies in this domain, it is not practical for practitioners and researchers to locate and synthesize such a large literature. Motivated by the above need and to find out what we, as the community, know about smells in test code, we conducted a ‘multivocal’ literature mapping (classification) on both the scientific literature and also practitioners’ grey literature. By surveying all the sources on test smells in both industry (120 sources) and academia (46 sources), 166 sources in total, our review presents the largest catalogue of test smells, along with the summary of guidelines/techniques and the tools to deal with those smells. This article aims to benefit the readers (both practitioners and researchers) by serving as an “index” to the vast body of knowledge in this important area, and by helping them develop high-quality test scripts, and minimize occurrences of test smells and their negative consequences in large test automation projects.

Climate chamber - Experiment - Methodology - Questionnaire - Survey - Thermal comfort
There are three main methods to improve thermal comfort in existing buildings: modeling, experiments and measurements. Regarding experiments, no standardized procedure exists. This article provides an answer to the question: “What is the most common practice for human thermal comfort experiments in (semi-)controlled environments?”. A total of 166 articles presenting results on 206 experiments were collected and analyzed to extrapolate the most common practice. The results are arranged in five main themes: subjects (e.g. number and age), climate chamber (e.g. surface area), thermal environment, experimental procedure (e.g. phases and duration), and questionnaire. A typical experiment was found to employ 25 subjects and to take place in a permanent climate chamber with a floor area of 24 m2 During the experiment, 3 air temperature variations are used. The test itself takes 115 min, but is preceded by a preconditioning and conditioning phase. The subject is given a questionnaire at regular intervals of 15 min, with questions highly dependent on topic, but including thermal sensation and comfort vote rated on a bipolar 7-level scale. Number of subjects, gender distribution, type and floor area of the climate chamber and utilization rate of the scale for rating thermal comfort and sensation are all linked to topic, as well as number of different air temperatures, whether conditioning is employed and questions in the questionnaire. Several links between experiment characteristics reciprocally are also identified.

Acidification - Anaerobic digestion - Economic barriers - Environmental regulations - Separation - Survey
Manure treatment technologies have been developed in Europe to better use animal manures and to reduce their environmental impact, but the adoption of these technologies in practice is regionally diverse and still limited. Also, little is known about the opinions of stakeholders towards manure treatment. This study aimed to identify stakeholder perceptions of (1) which factors can facilitate and hinder the implementation in practice, (2) which technologies have the most potential for successful adoption, and (3) how farm characteristics and scale of treatment operations affect priorities for technology adoption. This analysis used data from a survey of various stakeholders engaged in manure treatment in four European countries (Denmark, Italy, the Netherlands and Spain) that have large areas of high animal density, but diverse socio-economic, political and environmental conditions. Pressure from governmental regulations was perceived as a key factor that stimulated manure treatment in all four countries (70% of respondents). Processing manure to produce bioenergy was considered important in Denmark and Italy, but less important in Spain and the Netherlands. The major barriers to technology adoption were related to economic factors -lack of investment capital (60% of respondents), high processing cost (52%) and a long payback period (45%), while there was relatively little concern regarding transport and noise burden and health risks. Slurry separation and anaerobic digestion were perceived to have the greatest potential for a common adoption. Other preferred technologies were more country-specific (e.g. acidification in Denmark, composting in Spain, and drying and reverse osmosis in Netherlands). Manure treatment was considered to be less applicable at small livestock farms. Separation, composting and acidification were perceived to be more applicable at farm scale, while drying, anaerobic digestion, reverse osmosis at large, industrial scales. Our results imply that manure treatment will remain a regional activity. Policy measures and outreach strategies to alleviate the main barriers to the adoption of manure treatment are suggested.

Flood damage - Survey - Damage scanner - Jakarta
Flooding is a serious problem in Jakarta, and detailed estimation of flood damage is necessary to design optimal flood management strategies. This study aims to estimate flood damage in a densely populated area in Jakarta by means of a survey, to develop the relationship between flood characteristics and flood damage, and to compare the damage estimates from the survey with the damage estimates obtained by a flood damage model for Jakarta, i.e. the damage scanner model. We collected data on economic losses of the January 2013 flood in a survey of flood-affected households and business units in Pesanggrahan River. The actual flood damage in the survey area is US$ 0.5 million for the residential sector and US$ 0.7 million for the business sector. The flood damage for a similar event in the same area based on the damage scanner model is estimated to be US$ 1.3 million for the residential sector and US$ 9.2 million for the business sector. The flood damage estimates obtained by the survey approach are lower compared to the damage scanner approach due to different ways in obtaining flood damage data and in defining the maximum flood damage per object, the different spatial levels of analysis, and uncertainties in constructing the flood damage curves that were applied in the damage scanner

Attitudes - Europe - Food4me - Nutrigenomics - Personalised nutrition - Survey
Personalised diets based on people's existing food choices, and/or phenotypic, and/or genetic information hold potential to improve public dietary-related health. The aim of this analysis, therefore, has been to examine the degree to which factors which determine uptake of personalised nutrition vary between EU countries to better target policies to encourage uptake, and optimise the health benefits of personalised nutrition technology. A questionnaire developed from previous qualitative research was used to survey nationally representative samples from 9 EU countries (N = 9381). Perceived barriers to the uptake of personalised nutrition comprised three factors (data protection; the eating context; and, societal acceptance). Trust in sources of information comprised four factors (commerce and media; practitioners; government; family and, friends). Benefits comprised a single factor. Analysis of Variance (ANOVA) was employed to compare differences in responses between the United Kingdom; Ireland; Portugal; Poland; Norway; the Netherlands; Germany; and, Spain. The results indicated that respondents in Greece, Poland, Ireland, Portugal and Spain, rated the benefits of personalised nutrition highest, suggesting a particular readiness in these countries to adopt personalised nutrition interventions. Greek participants were more likely to perceive the social context of eating as a barrier to adoption of personalised nutrition, implying a need for support in negotiating social situations while on a prescribed diet. Those in Spain, Germany, Portugal and Poland scored highest on perceived barriers related to data protection. Government was more trusted than commerce to deliver and provide information on personalised nutrition overall. This was particularly the case in Ireland, Portugal and Greece, indicating an imperative to build trust, particularly in the ability of commercial service providers to deliver personalised dietary regimes effectively in these countries. These findings, obtained from a nationally representative sample of EU citizens, imply that a parallel, integrated, public-private delivery system would capture the needs of most potential consumers.

Agrifood - Consumer - Innovation - Naturalness - Survey - Technology acceptance
New agrifood technologies are often difficult to grasp for the public, which may lead to resistance or even rejection. Insight into which technology features determine public acceptability of the technology could offer guidelines for responsible technology development. This paper systematically assesses the relative importance of specific technology features for consumer response in the agrifood domain in two consecutive studies. Prominent technology features were selected from expert judgment and literature. The effects of these features on consumer evaluation were tested in a consumer study (n = 745). Fictitious technologies were used to avoid any uncontrollable contextual influences that existing new technologies may evoke. Results show that technologies that were seen as more natural and newer were perceived less risky, more beneficial, and were evaluated more positively. Technologies applied to food were judged to be more beneficial, but also more risky than those applied to non-food. Technologies used in the production process were perceived to be less risky and evaluated more positively than those used in the product. Technologies owned by the market leader were perceived to be more beneficial, and evaluated more positively than those that were freely available. In a next study (n = 440), effects of the technology features on consumer response were tested for existing new agrifood technologies. This study replicated the results for perceived naturalness, perceived newness, and place in the production process where the technology is applied. However, in contrast to the first study, we did not find an effect of application area (food versus non-food) and technology ownership.

European aquaculture - Finfish - Seed market - Selective breeding - Survey
The use of selective breeding is still relatively limited in aquaculture species. Information on such activities is sparse, hindering an overall evaluation of their success. Here, we report on the results of an online survey of the major aqua-culture breeding companies operating in Europe. Six main reared fish species were targeted. A total of 31 respondents contributed to the survey, representing 75 % of European breeding organizations. Family-based breeding schemes were predominant, but individual selection was more frequently applied in marine species. Artificial fertilization is the preferred means of reproduction; however, mass spawning is often used as a fallback method. The most frequently selected trait is growth performance, but the number of selected traits has been increasing over the years through the addition of traits such as disease resistance or product quality. The use of molecular tools is now common in all programs, mainly for pedigree traceability. An increasing number of programs use either genomic or marker-assisted selection. Results related to the seed production market confirmed that for Atlantic salmon there are a few dominant players at the European level, with 30–50 % market share. Only part of the European fish aquaculture industry today fully exploits selective breeding to the best advantage. A larger impact assessment still needs to be made by the remainder, particularly on the market share of fish seed (eggs, larvae or juveniles) and its consequences for hatchery stability.
