Consumer segmentation based on three dimensions of sustainable food consumption: a simultaneous analysis of meat, organic food, and sweet snack purchases based on household panel data in Germany.

The literature on sustainable food consumption laments two major gaps: First, the majority of previous studies analyzed consumer behavior based on survey data on consumers' self-reported behaviors and attitudes. Second, most existing studies focused on one dimension of sustainable food choices. This paper identifies and analyzes consumer segments based on the actual purchases of 8,400 households recorded in the GfK household panel data from Germany. We used three indicators of sustainable food consumption behavior: (1) the purchase of organic products as a proxy for the environmental impact of diets, (2) the purchase of meat as a proxy for the climate impact of diets, and (3) the purchase of sweet snacks as a proxy for the healthiness of a diet. The analysis yielded two larger segments with high expenditure shares for one type of unsustainable food (meat/sweet snacks, respectively), two small segments with above average (medium/high) expenditure shares for organic food, and a large 'mainstream' segment. The five consumer segments were further analyzed regarding the observed attitude-behavior gap, and the actual prices paid in different product categories. Clear gaps between stated and actual behavior were revealed with interesting differences between the five segments and the three sustainability characteristics. The analysis is a vital starting point for designing a holistic policy instrument mix to close the gaps and to reach a sustainable transformation of the food system.

[Refugee Minors from Ukraine and their Families - First Experiences from an Intercultural Practice for Child and Adolescents Psychiatry and an Outpatient Clinic for Refugees/Hamburg]. / Minderjährige Geflüchtete aus der Ukraine und ihre Familien ­ Erste Erfahrungen aus der interkulturellen Versorgungspraxis sowie der Flüchtlingsambulanz/Hamburg.

Due to the Russian invasion in Ukraine, many families were forced to flee to Germany, often having to leave relatives behind.The outpatient clinic for refugees at Universitätsklinikum Eppendorf coordinates the psychosocial and psychotherapeutic care for refugee minors from Ukraine in Hamburg. The intercultural practice for child and adolescents psychiatry offers on-site consultations for children and adolescents in camps in order to provide a low-threshold access to counseling and diagnostics. Diagnostic and therapeutic experiences to this point indicate the contribution of multifactorial stress to the development of symptoms in Ukrainian minors.The threat of war and displacement seems to be only one of many factors. Although there are some remarkable resilience factors for Ukrainian refugee children and adolescents in comparison to refugees from other countries of origin, the forced adaptation to living and studying conditions in Hamburg bears challenges for many. Additionally due to war experiences psychotherapeutic and psychiatric care is frequently needed. On Germany's side, there is a need for action to ameliorate the accessibility to the health care system for refugees and migrants. Support of therapists in this complex working field is thereby as important as advocacy for the needs of minor refugees in German society.

European household spending and socio-economic impacts on food behavior during the first wave of COVID-19.

This paper provides a European-level analysis using a large-scale survey of 13 countries to examine the power of relevant economic and socio-demographic characteristics to account for changes in food consumption and purchasing behavior during COVID-19. This was done by focusing on a two-level analysis of subject-related predictors highlighted in many existing country-level studies to test the generality of their significance. The Level 1 predictors relate to the individual households participating in the survey consisting of household composition, education, and location, as well as three types of perceived COVID-19 risks of infection, severity, and anxiety. Level 2 relates to the national level, and especially to the financial situation measured by the mean national Actual Individual Consumption (AIC) per capita in PPP, of the countries, in which the households reside. In terms of changes in food consumption, results show that household composition, education, and the household's perceived risk of both being infected by COVID-19 and being severely infected are significant predictors, although there are some differences between the two levels. Some possible explanations are as follows: putting food into one's body in the context of the pandemic is related to a household's financial situation, its composition, especially the presence or absence of children and older people, and its educational attainment, and through all these aforementioned to the perception of COVID-19 infection and its severity risks. Changes in food purchasing react significantly to the same predictors, but additionally, to all other predictors at both household and AIC levels. The household's location and perceived COVID-19 anxiety risks are thus also significant. Food purchasing depends much more on factors operating both at the individual household level and the AIC level together; for example, households' access to food is affected by both national and local lockdown restrictions that vary according to the location of the household.

"Corona Cooking": The interrelation between emotional response to the first lockdown during the COVID-19 pandemic and cooking attitudes and behaviour in Denmark.

For this study, the authors measured attitudes toward shopping for food and cooking, before and during the first lockdown due to the COVID-19 pandemic, among a sample of 526 Danish consumers, using an online survey. To analyse changes due to the lockdown, they applied a latent class Markov model, which revealed four states: middle of the road, love cooking (and like shopping), like shopping and cooking, and do not like shopping or cooking. In estimating transition probabilities, the findings reveal that most respondents remained in the same state before and during the lockdown, but those that changed were more likely to exhibit relatively higher liking of shopping and cooking. These states also reflect variations in people's food literacy and self-reported food consumption. Finally, respondents with stronger negative emotional reactions to the lockdown were more likely to change their states.

Changes in Food Consumption During the COVID-19 Pandemic: Analysis of Consumer Survey Data From the First Lockdown Period in Denmark, Germany, and Slovenia.

This paper focuses on changes in food consumption that occurred during the COVID-19 pandemic. Its objective is to map changes at individual consumer level and identify the influence of different factors related to the COVID-19 pandemic on changes in individual food consumption. We conducted a cross-sectional online survey among 2,680 residents of Denmark (DK), Germany (DE), and Slovenia (SI) using quota sampling for gender, age and regional distribution. Data on consumption frequencies before and during the pandemic were collected with a food frequency questionnaire in the spring of 2020 (during the first lockdown period) for important types of fresh food and non-perishable food. Our results showed that, depending on the type of food, 15-42% of study participants changed their consumption frequency during the pandemic, compared to before. In all the study countries, the food categories with the highest rates of change were frozen food, canned food, and cake and biscuits; among the food categories with lower rates of change were bread, alcoholic drinks, and dairy products. People across all three countries shopped less frequently during lockdown and there was an overall reduction in the consumption of fresh foods, but an increase in the consumption of food with a longer shelf life in Denmark and Germany. Interestingly though, we observed diverging trends in all food categories analyzed, with some people decreasing and others increasing their consumption frequencies, demonstrating that the pandemic had different impacts on people's lifestyles and food consumption patterns. Using the method of multinomial regression analysis, we identified factors significantly (p < 0.01, p < 0.05, p < 0.1) related to increases and decrease in individuals' consumption frequencies in different food categories. The factors include restrictions put in place in response to the pandemic (i.e., closure of physical workplaces, canteens, cafés and restaurants, schools, and childcare institutions), changes in households' grocery shopping frequency, individuals' perceived risk of COVID-19, income losses due to the pandemic, and socio-demographic factors. Interesting differences between the countries were detected, allowing insights into the different food cultures. Conclusions include implications for policy-makers and actors in the food supply chain on the issues of healthy diets, food system resilience, and behavior change.

How and Why Does the Attitude-Behavior Gap Differ Between Product Categories of Sustainable Food? Analysis of Organic Food Purchases Based on Household Panel Data.

Organic agriculture promotes the transformation toward sustainability because of positive effects for the environment. The organic label on food products enables consumers to make more sustainable purchasing decisions. Although the global market for organic food has grown rapidly in recent years, only a part of the organic product range benefits from this positive trend. To develop the organic market further, it is important to understand the food-related values and attitudes that drive the purchase of organic food. Previous research on this topic has suffered from two main weaknesses. Firstly, most studies have been based on surveys and rely on stated behavior instead of actual purchase behavior. Secondly, the focus of most extant studies is predominantly on organic food in general or on food products with a relatively high organic market share, such as milk and eggs. To address this knowledge gap, the present study analyzes the value-attitude-behavior relationship by means of structural equation modeling using household purchase panel data from GfK. The paper provides evidence for the existence of an attitude-behavior gap in the organic market, with this gap found to be much stronger in the case of meat, frozen food, cheese, and sweets than for organic purchases in total. Analysis in different product categories reveals that while purchase behavior is driven by the same food-related values, their relative importance differs.

Who Buys Products with Nutrition and Health Claims? A Purchase Simulation with Eye Tracking on the Influence of Consumers' Nutrition Knowledge and Health Motivation.

Nutrition and health claims are seen as a way of promoting healthy aspects of food. However, the results of previous studies have been contradictory regarding the effect of these claims on purchase. This study aims to achieve a better understanding of how the consumer characteristics 'nutrition knowledge' and 'health motivation' influence the purchase of products with nutrition and health claims and what role gaze behavior plays. We included gaze behavior in our analysis, as visual attention on the claims is a precondition to its influence on the purchase decision. In a close-to-realistic shopping situation, consumers could choose from three-dimensional orange juice packages labeled with nutrition, health, and taste claims. In total, the sample consisted of 156 consumers. The data were analyzed with a structural equation model (SEM), linking the purchase decision for products with claims to gaze data recorded with a mobile eye tracker and consumer and product-related variables collected via the questionnaire. Results showed that the variables in the SEM explained 31% (8%) of the variance observed in the purchase of products with a nutrition (health) claim. The longer a consumer looked at a specific claim, the more likely the consumer would purchase the respective product. The lower the price and the higher the perceived healthiness and tastiness of the product further heightened its likelihood of being purchased. Interestingly, consumers with higher nutrition knowledge and/or higher health motivation looked longer at the nutrition and health claims; however, these consumer characteristics did not show an effect on the purchase decision. Implications for policy makers and marketers are given.

Consumers' purchase decisions for products with nutrition and health claims: What role do product category and gaze duration on claims play?

Labeling food packages with nutrition and health claims is a widely used practice. This study aims to contribute to the literature by examining the gaze and purchase behavior of consumers regarding food products with nutrition and health claims. A close-to-realistic purchase situation with three-dimensional food packages with nutrition, health, and taste claims was simulated while the participants' eye movements were measured using head-mounted eye tracking glasses. In the purchase situation, two food categories with differing perceived healthiness were offered, orange juice and milk chocolate. In total, 156 consumers participated in this study which was undertaken in Germany. The findings indicate that each claim was noticed by at least 85% of the participants and health claims were looked at longer than nutrition or taste claims. Furthermore, when compared to other participants, the longer a participant looked at a specific claim, the more likely the participant was to purchase the respective product. Even though the product category had no effect on the gaze duration on claims, it affected the purchase behavior. Nutrition claims were preferred for orange juice while taste claims were preferred for milk chocolate. Health claims were preferred for neither. Marketers can benefit from this study, as it shows the gaze duration on claims influenced the purchase likelihood. Another important finding is that there are great differences between product categories regarding the type of claim consumers prefer.

Consumer preferences for sustainable aquaculture products: Evidence from in-depth interviews, think aloud protocols and choice experiments.

Fish from aquaculture is becoming more important for human consumption. Sustainable aquaculture procedures were developed as an alternative to overcome the negative environmental impacts of conventional aquaculture procedures and wild fisheries. The objective of this contribution is to determine what consumers expect from sustainable aquaculture and whether they prefer sustainable aquaculture products. A combination of qualitative research methods, with think aloud protocols and in-depth interviews, as well as quantitative methods, using choice experiments and face-to-face interviews, was applied. Data was collected in three different cities of Germany. Results revealed that sustainable aquaculture was associated with natural, traditional, local, and small scale production systems with high animal welfare standards. Overall, participants paid a lot of attention to the declaration of origin; in particular fish products from Germany and Denmark were preferred along with local products. Frequently used sustainability claims for aquaculture products were mostly criticized as being imprecise by the participants of the qualitative study; even though two claims tested in the choice experiments had a significant positive impact on the choice of purchase. Similarly, existing aquaculture-specific labels for certified sustainable aquaculture had an impact on the buying decision, but were not well recognized and even less trusted. Overall, consumers had a positive attitude towards sustainable aquaculture. However, communication measures and labelling schemes should be improved to increase consumer acceptance and make a decisive impact on consumers' buying behavior.

Motives of consumers following a vegan diet and their attitudes towards animal agriculture.

The number of consumers following a vegan diet has notably increased in many industrialised countries and it is likely that their influence on the food sector will continue to grow. The aim of the present study was to identify different segments of consumers according to their motivation for following a vegan diet. Another objective was to analyse the attitudes of these consumers towards animal agriculture. The main focus was to determine whether all consumers following a vegan diet oppose animal agriculture in general or if some of these consumers accept certain forms of animal agriculture. The 2014 study, conducted at seven vegan supermarkets in Germany, was based on face-to-face interviews with 329 consumers following a vegan diet. The open question on consumer motivations for adopting a vegan diet revealed three main motives: Animal-related motives (mentioned by 89.7% of the respondents), motives related to personal well-being and/or health (69.3%), and environment-related motives (46.8%). The two-step cluster analysis identified five consumer segments with different motivations for following a vegan diet. The vast majority of respondents (81.8%) mentioned more than one motive. We conclude that making a dichotomous segmentation into ethical versus self-oriented consumers, as previous authors have done, disregards the fact that many consumers following a vegan diet are driven by more than one motive. The consumer segments had significantly different attitudes towards animal agriculture. We identified consumers following a vegan diet (about one third of the sample) who might be open to forms of animal agriculture guaranteeing animal welfare standards going beyond current practices. The present study has interesting implications for the food sector and the agricultural sector.

[Factors contributing to the use of seclusion and restraint--a retrospective analysis in a Swiss clinic for child and adolescent psychiatry]. / Einflussfaktoren auf den Einsatz von Zwangsmassnahmen--Eine retrospektive Auswertung in einer Schweizer kinder- und jugendpsychiatrischen Versorgungsklinik.

Despite of the inculpatory effects of coercive measures on both patients and clinicans, only few publications regarding the influencing factors on the use of seclusion and restraint could be found. This study intended to investigate clinic- and patient-related factors which contribute to increasing und intensified incidents of seclusion and restraint. All incidents of coercive measures in a Swiss clinic during the years 2002 and 2003 were evaluated restrospectively. Data included detailed information about each coercive incident as well as patients and personnel involved. Statistics were conducted with SPSS. Adolescent age, female gender, previous experiences of violence and diagnoses of the ICD-10-category F9 and F6 were linked with high frequencies and intensive coercive interventions on the side of patient-related factors. Regarding clinic-related factors a fairly different handling could be found comparing different wards. Besides psychopathological aspects of the patients and structural characteristics of the clinic different understandings of disease-management, the nature of the therapeutic relations and environmental factors contribute to frequency, intensity and kind of coercive measures. A detailed evaluation of the use of coercive interventions can help to prevent unnecessary and incriminatory violence.

Surface modifications created by using engineered hydrophobins.

Hydrophobins are small (ca. 100 amino acids) secreted fungal proteins that are characterized by the presence of eight conserved cysteine residues and by a typical hydropathy pattern. Class I hydrophobins self-assemble at hydrophilic-hydrophobic interfaces into highly insoluble amphipathic membranes, thereby changing the nature of surfaces. Hydrophobic surfaces become hydrophilic, while hydrophilic surfaces become hydrophobic. To see whether surface properties of assembled hydrophobins can be changed, 25 N-terminal residues of the mature SC3 hydrophobin were deleted (TrSC3). In addition, the cell-binding domain of fibronectin (RGD) was fused to the N terminus of mature SC3 (RGD-SC3) and TrSC3 (RGD-TrSC3). Self-assembly and surface activity were not affected by these modifications. However, physiochemical properties at the hydrophilic side of the assembled hydrophobin did change. This was demonstrated by a change in wettability and by enhanced growth of fibroblasts on Teflon-coated with RGD-SC3, TrSC3, or RGD-TrSC3 compared to bare Teflon or Teflon coated with SC3. Thus, engineered hydrophobins can be used to functionalize surfaces.

Changes in the photosynthetic apparatus of diatoms in response to low and high light intensities

The centric diatom Cyclotella cryptica and two strains of the pennate diatom Phaeodactylum tricornutum were grown under low and high light intensities (300 lux and 3,000 lux) over 4-6 weeks. Growth was monitored by repetitive cell count. The culture media were replaced weekly to avoid morphological and biochemical alterations caused by nutrient depletion. The ultrastructure of the cells was examined by transmission electron microscopy. Alterations in the light-harvesting antenna systems were investigated by Western immunoblotting. Both diatoms reduced the plastid area, i.e. decreased the amount of thylakoid lamellae, under high light intensity. The thylakoids still ran in groups of three with parallel orientation within the chloroplasts. The girdle band lamellae were not affected. The amounts of storage compounds and vacuoles increased. SDS-PAGE of total cell protein followed by Western immunoblotting with antisera directed against subunits of the light-harvesting antenna systems of C. cryptica (cc-antiserum) and the cryptophyte Cryptomonas maculata (cmac-antiserum) revealed that both diatoms reduced the amount of antenna polypeptides under increased light intensity. The cc-antiserum immunodecorated two bands with relative molecular masses (Mr) of 18,000 and 22,000 in C. cryptica. Both decreased under high light conditions to 67.2 +/- 6.1%. Five to seven bands in the Mr range of 14,000-27,000 were recognized in P. tricornutum. They decreased to 83 +/- 5.3%. Furthermore, the immunolabeling pattern for both strains differed under the two light regimes. The cmac-antiserum immunodecorated two polypeptides with Mr of 24,000 and 23,000 in C. cryptica, while both strains of P. tricornutum had five polypeptides in the Mr range of 14,000-24,000 that showed some differences in staining intensities between the two strains and in response to the light intensity applied (AU)
