(in english): Modern agriculture faces soil erosion as one of its problems in the Czech Republic. Soil conservation practices are implemented to prevent erosion. This thesis reports on perception of the soil conservation practices by farmers themselves. Hypothesis of the research is based on declaration of organic farming in the Czech Republic: to specifically protect natural sources. Main research question is: Is there a difference in perception of soil conservation practices between certified organic farmers and farmers using conventional methods? As a concept to examine perception, this thesis uses the theory of planned behavior developed by Icek Ajzen. Results show that farmers' attitudes towards soil conservation practices in general are negative. Their attitudes can be explained by intermingling beliefs about erosion, the agriculture subsidy system and own soil quality. Specific practices are evaluated by other than anti-erosion effects. The farmers do not perceive social pressure from their peers to adopt soil conservation practices and their perceived control over adoption of a practice is low. Evaluating the level of difficulty of specific practices, smaller farmers feel substantial difficulties regarding financial issues. The results do not indicate a difference in perception of soil...

La consommation de suppléments alimentaires (DS) est répandue chez les athlètes et peut entrainer des conséquences telles que de faciliter la transition vers la consommation de substances prohibées ou échouer un contrôle anti-dopage causé par la consommation de DS contaminés. Une recherche utilisant des méthodes mixtes a été mené pour étudier le processus décisionnel sous-tendant la consommation de DS chez les athlètes. Dans la partie qualitative de l’étude, des athlètes universitaires (n=10) ont participé à des entrevues semi-structurées. L’analyse thématique des entrevues indique que les athlètes consommant des DS pour augmenter leurs performances sans obtenir les bénéfices escomptés seraient plus à risque de consommer des substances prohibées. Selon les données quantitatives (n=162), la prévalence de consommation des DS est élevée chez les athlètes et les hommes consommeraient plus de DS différents. La majorité des participants considéraient les nutritionnistes comme la source d’information la plus importante, mais peu d’entre eux (4%) ont utilisé leurs services. La participation d’athlètes élites à des entrevues semi-structurées (n=7) et à un questionnaire (n=36) dans le cadre d’une recherche préliminaire a permis une comparaison entre ces deux populations. Minimiser les risques susmentionnés pourrait être fait en ciblant les athlètes les plus vulnérables selon les critères suivants : 1) être un homme; 2) ne pas être inscrit dans un programme académique dans le domaine de la santé; 3) n’avoir jamais suivi de formation sur les DS; 4) consommer des DS pour améliorer ses performances sans obtenir les bénéfices escomptés ou 5) consommer plus de 3 DS différents. / Dietary supplements (DS) consumption is widespread among athletes. Despite evidence-based benefits, DS have proven to represent a risk for transitioning toward prohibited substances and even failing an anti-doping test due to contamination. A sequential mixed-method research design was used to explore the factors affecting athletes’ decision-making process underlying DS use. Varsity athletes (n=10) participated in semi-structured interviews that were thematically analyzed. In addition, a survey was conducted (n=162). Results indicated that athletes who consume DS to improve performance and experiencing little to no benefits could be more prone to transition toward prohibited substances. A high prevalence of DS use in varsity athletes was also observed (>90%), with males consuming more DS products. Nutritionists were ranked as the most importance source of information regarding DS; however, only 4% of athletes consulted one. A follow-up preliminary study conducted on elite athletes (semi-structured interviews: n=7; questionnaire: n=36) was also performed to compare those athlete populations. Minimizing DS consumption risks could be achieved by targeting the most vulnerable segment of the athletics population based on the following criteria: 1) being a male; 2) not being enrolled in a health program; 3) not having followed a DS workshop; 4) consuming DS to improve performance without experiencing significant improvements; or 5) consuming more than three different DS.

Resultatet visar oss att människors konsumtionsvanor påverkas av våra beteenden. Både attityden mot beteendet, subjektiva normer och vår upplevda kontroll över köpet påverkar det slutliga utfallet av konsumtionen av märkeskläder. Det gäller framförallt för klädköp som är avsedda för att förbättra individens självbild. Vi kan också se relativt tydliga indikationer på att konsumtionen av märkeskläder som är avsedda att förbättra individens självkänsla har störst inverkan av individens attityd. Om individen har en positiv inställning mot att köpa märkeskläder för att öka sin självkänsla kommer den också i större utsträckning genomföra köpet. / The result shows us that people's consumption habits are affected by our behaviors. Both the attitude towards the behavior, subjective norms and our perceived control over the purchase affect the final outcome of the consumption of branded clothing. This is especially true for clothing purchases that are intended to improve the individual's self-image. We can also see relatively clear indications that the consumption of branded clothing intended to improve the individual's self-esteem has the greatest impact on the individual's attitude. If the individual has a positive attitude towards buying designer clothes to increase their self-esteem, it will also make the purchase to a greater extent.

Electric vehicle adoption is one of the most prominent discussions currently facing the automotive industry, as this is an inevitable change towards a more sustainable future of transportation. Traditionally, car manufacturers adapt to consumer needs changing, thus prompting high relevance for understanding the consumer perspective and purchasing influences. This study aims to build a deeper understanding of the importance of internal and external factors on the EV consumer decision-making process, as well as to explore how the perception of such factors change upon adoption of electric vehicles. The study follows a positivism approach by conducting deductive research. A conceptual framework is developed based on review of research literature of rational choice theory, the consumer decision-making model, and factors impacting EV consumers, and constructing a model from the findings. Quantitative survey data is then collected following the model presented, and results are obtained using SPSS. Finally, the analysis applies the social identity theory, innovation diffusion theory, and theory of planned behavior for further evaluative discussions. The findings show that internal factors such as environmental awareness and fears and anxieties have a vital impact on consumers’ decisions of EV adoption and evaluation of EV alternatives, while social influences have a relatively small impact on the decision. The findings suggest a link between the theory of planned behavior and changing perceptions upon adoption of EV, in which factors relating to attitudes and perceived behavioral control are more susceptible to changing, while factors relating to subjective norms are not.

Despite many international and local attempts to end the practice of FGM/C, this practice continues to flourish in Nigeria and thus has a negative impact on the lives of girls and women on a daily basis. Furthermore, female genital mutilation is a serious form of violence against girls, women, and children that must be abolished worldwide. This study primarily sought to understand the sociocultural factors that influence the mothers' attitudes towards the continuation of FGM/C in Nigeria. The study used the theory of planned behaviour developed by Ajzen which proposes three distinct constructs as drivers of intention. This theory was deemed to be suitable for the study since sociocultural factors that contribute to the continuation of FGM in relation to mothers’ attitudes toward the practice can be interpreted or linked to the determinants of intention. In addition, this study used secondary data analysis and relied largely on reliable secondary sources.

Background: Fast furniture is a growing trend similar to fast fashion and fast food, implying that manufacturers produce large quantities of inexpensive furniture. At the same time, consumers use the furniture shorter and replace it more frequently. Fast furniture relies on high resource consumption, outsourced production, and furniture design that makes it necessary to replace it more often. This causes a decrease in quality and an increase in produced quantities. Most of the furniture worldwide is landfilled as it is not recyclable due to low-quality materials. One potential solution is implementing Circular Economic practices, including furniture rental as an alternative way of consumption. Consumer acceptance of this model is scarcely researched, but the formation of consumers' attitudes and intentions has been the subject of publications in other consumption contexts. The recent literature is reviewed, and a research framework was built based on the Theory of Reasoned Action and additional intrapersonal barriers and drivers. Purpose: This research aimed to explain the relationship between intrapersonal barriers and drivers with attitude and behavioral intention towards furniture rental. Further, it was aimed to show which furniture categories are most likely to be rented. Method: A quantitative approach deploying a self-administered online survey was chosen. 235 usable responses were gathered, which were analyzed using PLS-SEM to assess the hypothesized relationships. Conclusion: The findings show that the overall attitude towards furniture rental is positive. Trend orientation and perceived risk are the most influential antecedents of attitude and behavioral intention. Supporting the Theory of Reasoned Action, attitude is the strongest predictor of behavioral intention. Perceived sustainability value, perceived economic value, and materialism also significantly influence the intention to rent furniture. Familiarity with the Sharing Economy shows no significant influence. The study contributes to the existing literature on consumer intentions to use alternative consumption. A new research model was developed based on existing theory and literature. Managers can use the findings to alter, adapt, and build their furniture rental service offerings.

In the context of the world's increasing environmental challenges and the rise of green consumerism, promoting sustainable consumer behavior is more important than ever. This study aims at extending the understanding of consumers' purchase  intention of  environmentally friendly cosmetic products. With a theoretical starting point in theories of green promotion and the theory of planned behavior, a total of ten hypotheses and sub-hypotheses were formulated to answer the research question how green promotional cues can be used to affect consumers' beliefs and increase purchase intention. Central concepts in the study’s constructed conceptual framework are intrinsic cues which represent concrete characteristics of a product such as ingredients and formula, and extrinsic cues which are attributes not present within the product itself such as packaging and brand. A quantitative approach using an online survey in an experimental vignette designed questionnaire generated responses from a sample of 325 participants in three treatment groups, and the data was subsequently examined through statistical analysis. The study’s main findings show that intrinsic cues have a stronger influence on purchase intention than extrinsic cues but that extrinsic cues seem to have a stronger influence on consumers’ subjective beliefs. The study provides implications on how cosmetic companies can use the insights generated by the study when developing promotional strategies for green cosmetics.

Although many information system (IS) implementations are considered to have the resources necessary to be successful, they often fail. This is especially challenging for small IS providers who lack a proven process for gaining willingness to use and onboard a new customer. Hence, there is a need to develop a framework to identify potential pitfalls in such implementation matters, from designing the system until successfully onboarded customers. This paper aims to target this issue and proposes a framework for identifying common pitfalls during the implementation process of an IT system. Moreover, this paper applies the framework to an IS provider in the start-up phase by focusing on the system user. With the support of the framework and based on the company's context, this paper presents identified pitfalls and suggestions for actions that the IS provider can take to avoid them. IS models are selected and applied considering the company's needs and previous literature. The IS models considered are Value Network Analysis (VNA), Extended Technology Acceptance Model (TAM2), and Theory of Planned Behavior (TPB). As a result, seven pitfalls are identified considering organizational culture and leading change, user resistance, complexity, mandatory reliance, value demonstration, experience and control, and weak links.

<p>Behavior change is not a product of knowledge alone but by the other constructs within the Theory of Planned Behavior (TPB). This includes attitude, subjective norms, and perceived behavioral control. In order to ensure positive change in food safety behavior, researchers should explore the current situation before providing the necessary resources for consumers. This can be done through consumer needs assessments which explore practices, perceptions, demographics, and more. Along with that, major health events like the COVID-19 pandemic can increase risk perceptions of consumers which may lead them to follow safe (washing hands with soap and water) and unsafe food handling behaviors (washing fruits and vegetables with soap). Information spreads quicker during this digital age and this can cause consumers to follow certain behaviors. To assess information being spread, chapter 2 includes a study assessing COVID-19-related food safety information on YouTube early on in the pandemic. Chapter 3 and 4 contain longitudinal studies that used surveys and focus groups to assess consumer food handling practices and risk perceptions throughout the pandemic. Another factor is the type of food being handled. Consumers are not aware that certain foods like pet food (Ch. 5) and raw wheat flour (Ch. 6) can cause foodborne illness. Thus, they may not be handling these types of products as carefully. It is important to communicate that these foods can also cause foodborne illness. In the case of raw wheat flour, while commercial brands provide food safety messages on the packaging, consumers have a hard time finding and understanding the messages. All the studies within this dissertation explored multiple elements that can fall under the different constructs of the TPB in the context of the different factors that affect food safety behaviors. For example, previous studies have found that risk perception may fall under the construct of attitude because human perceptions can influence how a person feels about the situation. The objective of this dissertation is to explore different consumer food safety needs and explore how the elements within the needs assessments feeds into the TPB. With this information, researchers can advance the use of the TPB and researchers and food safety educators can ensure positive behavior change through the TPB.</p>

Especially in the context of complex organizational changes, employees’ support is crucial for success because change-supportive behaviors of employees are required to compensate for higher uncertainties related to the implementation and the consequences of the changes. Yet, change support of employees is no automatic reaction. Seen from a psychological perspective change support represents a planned behavior of employees that is preceded by change-supportive intentions formed in reaction to the specific changes at hand. Hence, it is important to understand how employees react to organizational changes and how they form change-supportive intentions. However, research on employees’ change reactions is a rather fragmented field that poses great challenges for researchers and practitioners striving to establish evidence-based approaches of change management. Therefore, the present research answers the call for more theoretical integration and refinement in the field of organizational research. Specifically, the present research makes use of the theory of planned behavior (TPB, Ajzen, 1991) which as is an established psychological theory for explaining human behaviors in social contexts. Based on this theoretical foundation, the present work systematically examines influences on the formation of change-supportive intentions from change-specific management factors (Study 1) and from personal factors (Study 2), as well as interrelational influences among the psychological determinants of change-supportive intentions (Study 3). Across all studies, the value of the TPB for understanding the formation of change-supportive intentions is supported. In addition, each study reveals unique insights. Revealing systematic linkages of change-specific management factors and psychological factors, Study 1 highlights the value of theoretical integration to promote evidence-based management. Study 2 finds affective organizational commitment to be an important predictor of change-supportive intentions with direct and indirect effects via the psychological determinants. Study 3 shows the relevance of a configurational perspective for more fully understanding the psychological processes involved in the formation of change-supportive intentions. Taken together, the appended studies contribute to the theoretical integration and refinement in change research and enable more systematic, well-founded diagnoses in change processes by providing scientific guidance for evidence-based change management.
