Recent studies have revalued Hazel Kyrk for her original works on consumption and the critique of neoclassical demand theory. Kyrk’s A Theory of Consumption (1923) opened up new perspectives for understanding the nature of consumption and revalued home economics as a central part of the economist agenda, taking distance from the first generation of home economists. This paper focuses on Kyrk’s post-1923 scientific production and professional activities. Our main purpose is to show her contributions to the quantitative foundations of consumption together with her attempt to feed contemporary research on consumers’ behavior with pragmatism, policy advice, and field knowledge. We selected specific issues: the education of consumers through information and a strategy of “critical consumption”; the analysis of strategic industries; the well-being of American families; and the importance of “invisible” objects (non-market activities) and their statistical processing.
Reward and threat processes work together to support adaptive learning during development. Adolescence is associated with increasing approach behavior (e.g., novelty-seeking, risk-taking) but often also coincides with emerging internalizing symptoms, which are characterized by heightened avoidance behavior. Peaking engagement of the nucleus accumbens (NAcc) during adolescence, often studied in reward paradigms, may also relate to threat mechanisms of adolescent psychopathology.
Methods:
47 typically developing adolescents (9.9–22.9 years) completed an aversive learning task during functional magnetic resonance imaging, wherein visual cues were paired with an aversive sound or no sound. Task blocks involved an escapable aversively reinforced stimulus (CS+r), the same stimulus without reinforcement (CS+nr), or a stimulus that was never reinforced (CS−). Parent-reported internalizing symptoms were measured using Revised Child Anxiety and Depression Scales.
Results:
Functional connectivity between the NAcc and amygdala differentiated the stimuli, such that connectivity increased for the CS+r (p = .023) but not for the CS+nr and CS−. Adolescents with greater internalizing symptoms demonstrated greater positive functional connectivity for the CS− (p = .041).
Conclusions:
Adolescents show heightened NAcc-amygdala functional connectivity during escape from threat. Higher anxiety and depression symptoms are associated with elevated NAcc-amygdala connectivity during safety, which may reflect poor safety versus threat discrimination.
The History of Economics Society (HES) initiated the History of Economics Society Bulletin (HESB) in 1979. Discussed at the 1978 meetings of the HES, the HESB was first conceived of as something “less” than History of Political Economy (HOPE)—i.e., an academic journal with a defined editorial line—but also “more” than just a newsletter for HES members (Caldwell 2021; Vaughn, this issue). Edited by Karen E. Vaughn (1979 to 1983) and William O. Thweatt (1984 to 1989), the HESB began by publishing short notes and abstracts of papers presented at the annual meetings of the HES. Research articles (i.e., peer-reviewed documents) appeared for the first time in 1988 and book reviews in 1989. A year after, the HESB became the Journal of the History of Economic Thought (JHET), a full-fledged society journal under the editorship of Donald Walker (1990 to 1998). First published directly by its editor and the HES, the JHET started producing four yearly issues in 1998 under contract with Carfax as publisher. Carfax was eventually purchased by Taylor & Francis (Medema, this issue), and a new contract was signed with Cambridge University Press, both during Steven Medema’s editorship (1999 to 2008).1
In 2022, the Welsh Government announced a basic income pilot for care leavers in Wales. This article uses this policy experiment to provide an insight into the relationship between devolution and social citizenship. This article makes two claims. First, the basic income pilot is part of an approach the Welsh Government has taken over the past twenty years to expand the idea of social citizenship to include rights to money. This is justified by a principle of progressive universalism, but this principle also has a wider UK context. Second, the financial constraints imposed by the UK Government frustrates the extent to which the Welsh Government can turn such experiments into reality.
The invitation is to discuss my JHET editorship, which ran from 2013 to 2018, in light of the once and future challenges of the journal. After accepting it, I gathered my recollections, perused back issues of the journal, and finally reviewed my correspondence and reports to the HES Executive Committee.
This study aimed (1) to identify distinct family trajectory profiles of destructive interparental conflict and parent-child emotional warmth reported by one parent, and (2) to examine whether these codevelopmental profiles were associated with the longitudinal development of children and adolescents’ self-reported internalizing and externalizing problems. Six longitudinal data waves from the German Family Panel (pairfam) study (Waves 2–7) from 722 parent-child dyads were used (age of children and adolescents in years: M = 10.03, SD = 1.90, range = 8–15; 48.3% girls; 73.3% of parents were native Germans). Data were analyzed using growth mixture and latent growth curve modeling. Two classes, harmonious and conflictual-warm families, were found based on codevelopmental trajectories of interparental conflict and emotional warmth. These family profiles were linked with the development of externalizing problems in children and adolescents but not their internalizing problems. Family dynamics are entangled in complex ways and constantly changing, which appears relevant to children’s behavior problems.
Two-dimensional turbulence transfers its energy towards the lowest mode in the domain, but domain geometry exerts a powerful control. On the sphere, with its three axes of rotational symmetry, angular momentum conservation prevents energy from entering the three lowest modes – those corresponding to the spherical harmonics $Y_1^0$ and $Y_1^{\pm 1}$ – because the amplitudes of these three modes are proportional to the three conserved components of the angular momentum vector. Non-spherical ellipsoids partly or completely break the rotational symmetry corresponding to angular momentum conservation. The flow on spheroids, which have only one axis of rotational symmetry, conserves only a single component of angular momentum. If the axis of symmetry is taken to be the $z$-axis, then only the $z$-component of angular momentum is conserved. Energy can flow into the other two lowest modes. The general triaxial ellipsoid breaks all rotational symmetries, thus angular momentum is not conserved, and energy can flow into any mode. We describe numerical experiments that confirm these predictions.
Differences in cultures, religious beliefs, and philosophical views suggest that leadership ethics may vary between Western and Eastern perspectives. However, ethical leadership scales are mostly rooted in Western conceptualization. This systematic review explores the cultural contributions, philosophical perspectives, and underlying theories shaping the measures of ethical leadership. A comprehensive search across Scopus, Web of Science, ProQuest Management, and Emerald Insight from 1990 to 2021 yielded over 3900 articles, with only 15 focusing on an Eastern conceptualization of ethical leadership. Findings reveal that Eastern ethical leadership encompasses unique dimensions, including leaders’ responsibility and concern for long-term sustainability, often overlooked in existing measures. Despite some similarities in virtues and values between Eastern and Western philosophical views, past studies predominantly employed Western theoretical perspectives to explain ethical leadership. This review highlights the imperative for measures that authentically capture Eastern cultural distinctions, crucial for advancing ethical leadership research amid the East’s increasing global influence.
Growing numbers of people help and support family members, friends or others due to long-term health problems, disability or older age–related needs. While care-giving can bring fulfilment and meaning to peoples’ lives, it can negatively affect individuals’ financial wellbeing. Much of the evidence in this area is quantitative, while the subjective, in-depth experience of how unpaid care decisions affect financial wellbeing remains relatively underexplored. This scoping review explores what is known about how unpaid carers experience and understand the financial consequences of providing care. It identified 35 studies containing qualitative evidence and, through thematic analysis, identified four overarching themes: (1) direct and indirect costs of caring; (2) social, cultural and institutional care and work decision-making; (3) the unequal cost of caring; and (4) personal finance and carer wellbeing. Findings indicate that unpaid caring affects financial wellbeing in multiple, overlapping ways. The financial consequences are experienced unequally, with systems, circumstances and contexts serving to exacerbate or reduce these negative effects. Crucially, our analysis reveals the paucity of qualitative research specifically focused on unpaid carers’ financial wellbeing. There is a significant gap in the literature regarding whether, and how, individuals understand the future financial implications of unpaid care-giving, or whether longer-term financial consequences are considered when making decisions about care. Future research designed to address this gap, with greater emphasis on the personal, social and structural influences on care-related financial decision-making, could offer important insights for developing policies and practices aimed at improving the financial wellbeing of carers as they age.
Pectin is composed of a group of complex polysaccharides that are naturally found in various plants and are associated with a range of beneficial health effects. Health outcomes from dietary pectin can vary depending on botanical origin, dietary dose and structure of pectin. The objective of this scoping review is to build a comprehensive overview of the current evidence available on intervention studies conducted in humans and to better understand the possible knowledge gaps in terms of structure–function relationships across the different health-related effects. PubMed and Embase databases were searched using PRISMA-ScR guidelines, yielding 141 references (from the initial 3704), representing 134 intervention studies performed between 1961 and 2022 that met inclusion criteria. Studies were divided into six categories, which included gut health, glycaemic response and appetite, fat metabolism, bioavailability of micronutrients, immune response and other topics. Review of these human intervention studies identified a variety of cohort characteristics and populations (life stage, health status, country), sources/types of pectin (i.e. citrus, sugarbeet, apple, other and non-defined), intervention timeframes (from one single intake to 168 d) and doses (0.1–50 g/d) that were tested for health outcomes in people. Gut health, post-prandial glucose regulation and maintenance of blood cholesterol represented the largest categories of studied outcomes. Further research to strengthen the structure–function relationships for pectin with health properties and associated outcomes is warranted and will benefit from a more precise description of physico-chemical characteristics and molecular compositions, such as degree of esterification, weight, degree of branching, viscosity, gel formation and solubility.
The literature on John Maynard Keynes’s activity as an investor has substantially grown in the last decade (e.g., Chambers and Dimson 2013; Accominotti and Chambers 2016; Chambers and Kabiri 2016; Cristiano, Marcuzzo, and Sanfilippo 2018; Marcuzzo and Rosselli 2018; Marcuzzo and Sanfilippo 2016, [2020] 2022). The contribution of the present paper is to investigate a specific feature of Keynes’s investment activity on his own account: his preference for American rather than British Investment Trusts. While this feature has also been observed in his investments on behalf of King’s College (Chambers and Kabiri 2016), we focus here on his personal portfolio, and we also provide a set of possible explanations for his preference. We maintain that some reasons have to do with the different structure and characteristics of the Investment Trusts in the two countries. Others relate more closely to the kind of investment policy typically adopted by the American Investment Trusts, which was much more in line with Keynes’s own approach to investment—especially regarding the stocks selection. We also attribute a role to his epistemological approach, i.e., the view that, although a full and perfect knowledge is not reachable by individuals due to the radical uncertainty characterizing the environment (“we simply don’t know,” Keynes 1937) and to the limitations of the human mind, reliable information remains, however, a guide for rational decision making, also in financial markets. Following this approach, as we will show, Keynes preferred to delegate his investment choices in the US stock market to those professionals—the managers of the Investment Trusts—who possessed, in his opinion, the wider set of reliable information on that market, while keeping for himself the investment choices in the UK stock market.
Thomas Taylor's parody of Mary Wollstonecraft's support for rights of women and humans raises a question: does his satire unwittingly propose a defence of animal rights found in Wollstonecraft's arguments? While Wollstonecraft's later works do not mention animal rights, her early educational writings offer arguments on animal ethics. These works explore the value of animals from moral, theological, and consequentialist perspectives, emphasizing both their instrumental and inherent value. This article argues that Wollstonecraft's moral psychology and theology highlight a benevolent attitude towards animals, underscoring their value beyond their utility.
This article discusses the significance of the extensive data-gathering procedures incorporated into recent synodal preparations and how they advance Pope Francis’s commitment to forging a church informed by a dialogue between theological ideas and empirical realities. Drawing on my prior case analysis of the Synod on the Family, I argue that despite the limits in place then on lay participation in the formal synod discussions, the diversity of the laity’s self-reported experiences penetrated the bishops’ deliberations. This achievement is in part a function of the synod communication structure whereby participants are allocated to shared-language groups, thus avoiding self-selection based on a priori doctrinal or country-specific biases; the resulting (forced) dialogue with difference helps foster the gradual development of more inclusive doctrinal framings as seen in the post-synodal Amoris Laetitia. In a historic expansion, the Synod on Synodality formally includes lay voting participants and therefore lay perspectives will directly shape the synod proposal outcomes. Like the bishops, lay Catholics do not speak with one voice, and thus the task of finding moral consensus will still necessarily require respectful mutual listening and reciprocal dialogue.
Navigating the complex relationship between violence and psychosis can frequently be challenging. Psychiatrists may find assessing and managing the risk of violence in this context daunting. In their article on the topic, Anderson et al helpfully summarise the role that psychopathology can play in this process. However, although careful elucidation of an individual's experiences may assist in the nuanced formulation of their risk and could offer a specific focus for interventions, the approach has potential shortcomings in certain settings. For some phenomena the link with violence is unclear and it may be constellations of symptoms that are important. Causal pathways are not always linear and there may be important mediators linking psychopathological features to behavioural outcomes. In the resource-limited settings in which many contemporary health services operate, a detailed assessment of psychopathology may be hampered by time or other constraints. Alternative, more scalable solutions may therefore be needed in particular scenarios.
With the development of overall design methodologies for hypersonic vehicles and their propulsion systems, nozzles should expand airflow in a short length and provide sufficient thrust. Therefore, the large expansion ratio single expansion ramp nozzle (LSERN) is widely used. The form of the overexpanded flow field in the nozzle is complex, under the conditions of nozzle start-up, low speed and low nozzle pressure ratio (NPR), thereby negatively influencing the entire propulsion system. Thus, the nozzle flow separation pattern and the key factors affecting the flow separation pattern also deserve considerable attention. In this study, the design of SERN is completed using the cubic curve design method, and the model is numerically simulated for specific operating conditions to study the flow separation patterns and the transition processes of different patterns. Furthermore, the key factors affecting the various flow separation patterns in the nozzle are investigated in detail. Results show that the LSERN in different NPRs appeared in two types of restricted shock separation (RSS) pattern and free shock separation (FSS) pattern, as well as their corresponding flow separation pattern transition processes. The initial expansion angle and the nozzle length affect the range of NPRs maintained by the FSS pattern. The initial expansion angle affects the pattern of flow separation, whereas the nozzle length remarkably influences the critical NPR during transition.
