\"This book is about preferences, principally as they figure in economics. It also explores their uses in everyday language and action, how they are understood in psychology and how they figure in philosophical reflection on action and morality. The book clarifies and for the most part defends the way in which economists invoke preferences to explain, predict and assess behavior and outcomes. Hausman argues, however, that the predictions and explanations economists offer rely on theories of preference formation that are in need of further development, and he criticizes attempts to define welfare in terms of preferences and to define preferences in terms of choices or self-interest. The analysis clarifies the relations between rational choice theory and philosophical accounts of human action. The book also assembles the materials out of which models of preference formation and modification can be constructed, and it comments on how reason and emotion shape preferences\"-- Provided by publisher.

Theories in motivation science, and in psychological science more generally, are in a state of fragmentation that impedes development of a robust body of knowledge. Furthermore, fragmentation hinders communication among scientists, with practitioners, and with policymakers and the public. Theoretical integration is needed to overcome this situation. In this commentary, I first provide an overview of the integrative frameworks presented in this collection of articles. Based on this overview, I discuss if and when we should integrate theories. Several non-trivial conditions need to be met for integration, including convergence of phenomena, constructs, and theoretical propositions. Next, I address strategies for integration, including rules for merging constructs and ways to integrate propositions. I also discuss how the generation of integrative frameworks, if not successfully enacted, can paradoxically lead to further proliferation rather than a reduction of theories. In contrast, successful integration reduces redundancy and simplifies the conceptual space used to describe, explain, or predict a set of phenomena. Successful integration may require not only theoretical work but also empirical validation, strategic efforts in the scientific community, and change of institutional policies. In conclusion, I argue that within-discipline integration alone is not sufficient to overcome the current theoretical stagnation in the field. Attention to advances in neighboring disciplines, formalization of models of motivation, and theoretical differentiation to consider the specificity of constructs, populations, and contexts are needed as well.

Background Recently published reports call for an increase in the number of engineering graduates and suggest appropriate characteristics that these graduates should embody. Accomplishing such change first requires understanding why students choose to pursue engineering degrees. Purpose (Hypothesis) Framed in motivation theory, our purpose was to better understand how students choose engineering by answering the question: How do engineering students' engineering‐related value beliefs contribute to their choices to engage and persist in earning engineering degrees? Design/Method This research uses Eccles' expectancy‐value theory in a qualitative, longitudinal examination of undergraduate students' choices to enroll and persist in engineering majors. In particular, the focus of this work is Eccles' subjective task value (STV) construct, which incorporates the personal importance an individual assigns to engaging in an activity. Using a multiple case study method approach, participants included eleven students (five men and six women) at a U.S. technical school. Results Results demonstrate that different patterns exist in the types of value or personal importance that participants assign to earning an engineering degree. Moreover, a primary differentiating feature of these patterns is whether or not participants choose engineering because it is consistent with their personal identity or sense of self. Conclusions We conclude that values are very important in students' choices to become engineers. To increase persistence rates we must focus on values, especially by helping students connect their personal identities to engineering identities.

Extreme value theory (EVT) provides tools for assessing risk of highly unusual developments, such as financial market crashes. This book presents a synthesis of recent research, with emphasis on dependent observations. It concentrates on modern topics, such as compound Poisson approximation, processes of exceedances, and nonparametric estimation methods, which have not been focused on in other books on extremes. Along with examples from finance and insurance that illustrate the methods, the book includes over 200 exercises, making it useful as a reference book, self-study tool, or comprehensive course text.

\"Economists dream of equilibrium. It's time to wake up. In mainstream economics, markets are ideal if competition is perfect. When supply balances demand, economic maturity is orderly and disturbed only by shocks. These ideas are rooted in doctrines going back thousands of years yet, as James K. Galbraith and Jing Chen show, they contradict the foundations of our scientific understanding of the physical and biological worlds. Entropy Economics discards the conventions of equilibrium and presents a new basis for thinking about economic issues, one rooted in life processes--an unequal world of unceasing change in which boundaries, plans, and regulations are essential. Galbraith and Chen's theory of value is based on scarcity, and it accounts for the power of monopoly. Their theory of production covers increasing and decreasing returns, uncertainty, fixed investments over time, and the impact of rising resource costs. Together, their models illuminate key problems such as trade, finance, energy, climate, conflict, and demography. Entropy Economics is a thrilling framework for understanding the world as it is and will be keenly relevant to the economic challenges of a world threatened with disorder\"-- Provided by publisher.

Health professionals' engagement in translational health and medical research (HMR) is fundamental to evidence-based practice leading to better patient health outcomes. However, there is a decline in the number of health professionals undertaking research which has implications for patient health and the economy. Informed by the motivation-based expectancy-value-cost (EVC) and self determination theories (SDT), this systematic literature review examined the barriers and facilitators of health professionals' (HPs) motivation to undertake research. The literature was searched between 2011 and 2021 for relevant peer-reviewed articles written in English, using CINAHL Complete, Informit, Medline Ovid, Medline (PubMed), Scopus, Web of Science and Google Scholar databases. This systematic review was performed and reported in accordance with the PRISMA guidelines. Identified barriers to HPs' engagement with research included the lack of knowledge, skills, and competence to conduct research, lack of protected research time, lack of funding and lack of organisational support. Integration of the findings of this review based on the EVC and SDT theories indicate that research capacity, ie, expectancy and competence is highly influenced by attitude, ie, the type of value (attainment, intrinsic or utility) and connection attributed to research. HPs who had very positive attitude towards research demonstrated all three values and were keen to take up research despite the barriers. Those who had a positive attitude were only motivated to do research because of its utility value and did not necessarily see it as having personal relevance for themselves. HPs who were unmotivated did not see any personal connection or relatedness to the research experience and saw no value in research. The attitude HPs hold in their value of research is a catalyst for motivation or amotivation to engage in research as it directly influences the relevance of barriers. Facilitators that expedite the research journey have been attributed to research training, mentorship programs and supportive organisational research culture. Motivation of HPs explored through EVC and SDT is critical to the maintenance of a research culture and the clinician-researcher development pipeline.

Purpose - Although the organic market has expanded in recent years, it remains small. Some researchers argue that consumers' lack of knowledge concerning organic food is an important factor slowing down growth. This paper aims to focus on the factors influencing objective and subjective knowledge with regard to organic food production and the relationship between both types of knowledge and consumer attitudes and motivations towards organic food and its consumption.Design methodology approach - A literature review is presented, relating to the impact of knowledge on behaviour in general and, more specifically, on organic food consumption. Several hypotheses are formulated concerning the relationship between objective and subjective knowledge, attitudes and organic food consumption and these are tested on organic vegetable consumption in Flanders (Belgium). Multiple regression models, a probit model and an analysis of variance are applied to a sample of 529 completed questionnaires (response rate=44 per cent). The respondents were selected in January 2007 using a convenience sampling technique. Socio-demographic variables are used to check representativeness.Findings - In the sample, the level of objective knowledge regarding organic vegetables is high. Attitudes towards the consumption of organic vegetables are generally positive. The strongest motivations for consuming organic vegetables are that they are produced without synthetic pesticides, are better for the environment, healthier, of higher quality and taste better. The strongest perceived barriers are overly high prices and lack of availability. Objective and subjective knowledge with regard to organic food production show a positive correlation. Higher levels of objective and subjective knowledge concerning organic food are positively related to a more positive attitude towards organic food, greater experience of it and a more frequent use of information. Membership of an \"ecological organisation\" (VELT) is also related to higher levels of knowledge. Some variables have a significant positive relationship with subjective knowledge, but not with objective knowledge. Attitude is significantly and positively influenced by subjective knowledge, VELT-membership, norm, motivations and female gender. Perceived barriers have a significant negative influence on attitude. The likelihood of consuming organic vegetables is significantly and positively influenced by VELT-membership, subjective knowledge, attitude, motivations and the presence of children in the household. Whilst objective knowledge, norm and female gender have a significantly positive influence on attitude towards organic vegetables, they have no significant influence on the likelihood of actually consuming organic vegetables.Originality value - Whilst several researchers argue that knowledge may be a very important factor in increasing organic food consumption, few have studied the mechanisms behind it. To the authors' knowledge this is the first paper describing the impact of knowledge on organic food consumption in such detail. By assessing the impact of knowledge, as well as other factors, on organic food consumption, greater insight is gained with regard to organic food consumption behaviour.
