Having faced not one financial car crash but several in less than a generation, it is little wonder today’s risk-takers, investors, households and corporates alike, are sticking rather than twisting, saving not spending, braking not accelerating, their animal spirits anaesthetised. Although collectively damaging, this is the individually prudent thing to do. We are facing a twenty-first-century ‘paradox of thrift’, whose psychological scars might easily persist as long as those of its twentieth-century counterpart. The upstream effects of this reduced risk-taking can be clearly seen in the damped dynamism and caged animal spirits of both businesses and households. In the words of Austrian economist Joseph Schumpeter, the forces of ‘creative destruction’ have been significantly and persistently diminished by the sequence of crises, stunting innovation, enterprise and hence the dynamism of our economies. For businesses, those caged animal spirits have manifested themselves in reduced numbers of firms entering and, just as importantly, exiting the market. Entry and exit rates for UK firms are around a third lower today than at the time of the GFC. Entrepreneurs are more fearful of starting new businesses, despite them being the wellspring of innovation and jobs.
The discovery and analysis of immature Neandertal remains have yielded significant insights into Neandertal growth and development, despite numerous historical challenges in the curation and study of these fossils. The relatively large number of immature Neandertal remains, attributed in part to their practice of intentional burial, has allowed for extensive ontogenetic studies. Early research focused on the timing of Neandertal trait emergence, and recent studies have expanded to include aspects such as birth, gestation, and growth rates. Notable differences between Neandertals and modern humans have been observed, particularly in craniofacial growth, brain development, and dental formation. Despite some evidence suggesting accelerated dental development in Neandertals, there is still considerable debate. Postcranial studies have highlighted distinctive features that emerge early in Neandertal growth, although discrepancies between dental and skeletal maturity remain. Future research is poised to benefit from integrated approaches that combine cranial, dental, and postcranial data and consider a wide range of comparative samples. Understanding Neandertal growth within a developmental context not only enhances our knowledge of Neandertals but also provides broader insights into human evolutionary biology.
We solve three problems raised in recent articles by Longstaff [Bull. Aust. Math. Soc.102 (2020), 226–236; 103 (2021), 260–270; 104 (2021), 78–93]. We show that: (1) the length of an irreducible family of $n\times n$ rank-one matrices can take any value $1,2,\ldots ,n$; (2) the slot length of an irreducible pair of $n\times n$ matrices can exceed $2n-4$; and (3) we give bounds on the $1$-minimum spanning lengths of irreducible pairs.
Malnutrition remains a major public health challenge in low- and middle-income countries and disproportionately affecting children under five. Eggs, given their high nutrient density and relative physical or economic accessibility, have been tested for their effect on improving nutritional outcomes in children under five. However, findings from scientific exercises to test the impact of egg-based trials on child growth have not been systhematically pooled and synthesised. Therefore, this meta-analysis aimed to synthesise evidence on the impact of egg-based interventions on the nutritional status of children underfive as determined by weight-for-height Z-score (WHZ), weight-for-age z-score (WAZ), and height-for-age z-score (HAZ). Research articles of randomised controlled trials published between 2013 and 2023 were identified through a comprehensive search of PubMed/MEDLINE, Web of Science, CINAHL, Embase, Science Direct, Google Scholar, and African Index Medicus data bases. Articles evaluated the effect of egg-based interventions against alternative diets, behaviour-change education, or no alternative intervention were included. Primary outcomes are WHZ, WAZ, and HAZ. Random-effects models were used to pool effect sizes (mean difference), and subgroup analyses and meta-regression explored sources of heterogeneity. Publication bias was assessed using funnel plots and Egger’s test. Seven studies involving 3673 children met the inclusion criteria. Egg-based intervention significantly improved WAZ (MD: 0.33; 95% CI: 0.11–0.55) and WHZ (MD: 0.30; 95% CI: 0.12–0.48). However, no significant effect was observed on HAZ (MD: 0.05; 95% CI: –0.05–0.14). It is figuredout that egg-based interventions can improve weight-related nutritional outcomes (WHZ and HAZ) among children underfive in sub-Saharan Africa, but not linear growth (HAZ).
The function, composition and processes underlying the formation and maturation of the skeleton, bone the organ and bone the tissue, are the focus of this chapter. Knowledge of the immature infant skeleton and its inherent weaknesses and susceptibility to physical injury, facilitates understanding the morphologic manifestations of bone injury and the body’s response to associated tissue damage. The skeleton is a complex structure that plays a variety of different roles crucial to life. It is composed of many individual bones that are constructed of proteins, minerals and the cells specific to bone, namely, the families of osteoblasts and osteoclasts. Bones form through enchondral and intramembranous ossification, and these processes are complex and tightly regulated by molecular genetics and cell-signaling pathways. Understanding the structure of the skeleton and its growth and development provides the foundation to understand its susceptibility to trauma and the pathology induced by injury and tissue damage.
B. infantis abundance in the infant gut may be associated with growth and health outcomes. However, these relationships have not been widely studied in settings where B. infantis is a dominant early-life commensal and growth faltering is prevalent. Here, we estimated associations between neonatal B. infantis abundance and anthropometric outcomes up to 6 months of age in generally healthy infants in Dhaka, Bangladesh; diarrhoea and hospitalizations (at 1–2 and 6 months) were secondary morbidity outcomes. B. infantis stool absolute abundance was quantified by qPCR; for each infant, the primary exposure was mean abundance (0–28 days). Length-for-age, weight-for-age, and weight-for-length z-scores were derived at birth, 2, 3, and 6 months. Neonatal B. infantis abundance had a bimodal distribution, with 63% of infants having detectable B. infantis by 28 days of age. Anthropometric z-score distributions were shifted down, with means below zero. Neonatal B. infantis abundance was not associated with any anthropometric outcome at 2, 3, or 6 months of age (n = 830), or with the risks of diarrhoea or hospitalizations. The lack of association of neonatal B. infantis abundance with growth outcomes suggests that promoting early B. infantis colonization is unlikely to improve growth in populations with postnatal faltering.
Understanding trends in height and BMI, along with trajectories of weight status, is crucial to identifying the optimal timing for intervention. The objective of this study was to describe trends in height and BMI among children and adolescents and identify the trajectory of weight status over time. This was a longitudinal study with data collected annually (2013–2020). A total of 41 325 students aged 5–18 years from forty-seven schools participated in the study, and a subsample of 11 535 participants with at least five BMI measurements was used for the analyses. Mixed-effects analysis showed significant increases in height over the years for boys (0·19 cm, standard error 0·01, P < 0·001) and girls (0·15 cm, standard error 0·01, P < 0·001). Regarding BMI, an increasing trend over the years was also found in boys (0·04 kg/m2, se 0·01, P < 0·001) and girls (0·04 kg/m², se 0·01, P < 0·001). Analysing weight status trajectories, three groups were identified: consistently normal weight (males 63·7 %, females 64·5 %), increasingly overweight (males 21·8 %, females 20·7 %) and increasingly obese (males 14·5 %, females 14·8 %). We conclude that in adolescence, height was below expected, indicating that children are not reaching their maximum growth potential. Furthermore, the identification of increasing trajectories of overweight and obesity, starting in childhood, emphasises the progressive nature of excessive weight gain before adulthood. These findings highlight the early onset of nutritional deviations in this population, suggesting the need for interventions to promote healthy weight as children transition into adolescence to mitigate future health risks.

India was a poor and unequal country in 1947. Much of its labour force was in low-productivity agriculture, but it had a significant, if small, industrial sector. A plausible trajectory going forward was that rapid industrial growth would draw labour into higher-productivity areas, reducing poverty and inequality. But India went down a different path, beginning with an emphasis on heavy industry. This increased the economy’s productive capacity, but did not generate enough jobs to dent poverty and inequality. Over-regulation and neglect of exports contributed to slow growth until 1980, though agricultural productivity rose with the introduction of new high-yielding varieties of crops in some areas. After 1980, and especially after 1991, policies became more friendly to markets and business and India grew rapidly, led by growth in the services sector. This, however, did not create jobs at the same rate, because the growth was skill- and capital-intensive. Poverty fell substantially, but inequality spiked, and job creation remains a big concern.

It has been a remarkable journey for India from the nation’s independence in 1947 to now. Economic performance has been mixed, with growth remaining sluggish during the first three decades, and picking up only after the mid-1990s. On the political front, with free media, secularism and a vibrant democracy, India was an outlier in the developing world; it resembled some of the most advanced economies in the world. This chapter is a study of this unusual growth path, over the last seventy years, with a focus on how the economy and politics impacted each other. It is argued that, while early political choices may have slowed growth during the early decades, they played a vital role in India rising to be among the world’s fastest-growing nations in the first decade of the twenty-first century.

Pakistan’s seventy-five-year economic history can be divided into three distinct periods. The first decade after 1947 was a period of low growth, but one in which a functioning state was set up from scratch and rapid industrialization occurred. The 1960–1990 period saw high economic growth but high costs, including the secession of Pakistan’s eastern wing (now Bangladesh), the Soviet occupation of Afghanistan and the ensuing civil war, which spilled over into Pakistan. Between 1990 and 2022, growth halved, primarily due to the continuing conflict in Afghanistan – this time with the US- led invasion after 9/11 – coupled with poor economic management in dealing with recurring balance-of-payments crisis and frequent recourse to the IMF. The key factors responsible for these changes are identified through ten turning points, which capture major events both internal and external and the ensuing structural changes, including in the composition of the ruling elite. Failure to undertake economic reforms was a key factor in Pakistan’s overall disappointing performance after a promising start.
Abstract: In this chapter, English examines Human Nature and Conduct (1922) through the lens of Dewey’s broader theory of how humans learn. The chapter shows how Dewey’s emphasis on the productive role of uncertainty in human learning processes relates to how he differentiates between a habit as “a vital art” and a habit as “a mechanical routine.” The chapter then examines how Dewey expands his critique of traditional education by showing how traditional schooling separates habits from thought, creating mechanistic habits that do not allow for young people to learn the habit of learning – the habit to grow through encounters with difference. Using an example of classroom dialogue, English discusses how classrooms can become educational environments that foster the types of habits associated with educative growth. The chapter concludes by emphasizing that Human Nature and Conduct offers insight into not only the education of young people but also the education of grown-ups. Accordingly, adult society must construct environments for themselves that nurture thought and thereby help them develop rich perceptions of interdependencies between humans. Ultimately, the chapter provides an understanding of why making learning a habit is essential for the growth of an equitable, democratic future of education and society.
Abstract: This chapter examines John Dewey’s concept of moral education as growth, emphasizing its implications for moral development beyond his earlier work. While Moral Principles in Education (1909) presents Dewey’s approach to moral education through social participation, it does not incorporate his later view of growth as the sole moral end. Waks points to the need for the reconstruction of Dewey’s moral education theory in light of Human Nature and Conduct (1922), where he defines morality as the expansion of conduct in meaning. As Waks illustrates, Dewey’s later theory of growth introduces a tension between cooperative participation and individual moral development. The chapter shows how, for Dewey, true moral growth requires openness to new experiences, creative problem-solving involving new ends and new means, and self-transformation, sometimes in conflict with established social norms and cooperative action. This challenges educators to cultivate both group cooperation and individual moral experimentation. Waks concludes that a reconstructed Deweyan moral education must balance social engagement and cooperation with fostering independent growth, requiring educators to create environments that encourage both communal participation and personal moral discovery.
Abstract: In Human Nature and Conduct (1922), Dewey writes that bad habits are ones that have a “command over us” making us “do things we prefer not to do,” because as he puts it, “we are the habit.” In this chapter, Striano describes how education has a role in our understanding of the command of habit over our lives. The chapter considers how within the process of growth we can start reshaping our habits, making them increasingly intelligent so as to inform “intelligent dispositions.” Intelligent dispositions are central to helping us come to perform new, more reflective, courses of action in the world. The chapter concludes with the ideas that such intelligently reconstructed habits − ones that have been channeled through educative experiences which account for both human plasticity and the changes and “obstacles” in our environment − have the power to determine an effective transformation of our attitudes, behaviors, and understandings and, therefore, of our selves.
Abstract: In this chapter, Saito examines what the contemporary significance of Deweyan growth can be, if indeed it continues to have significance. In Human Nature and Conduct (1922), John Dewey elaborates his apparently paradoxical idea that growth means growing, “continued growth.” Today, the word “growth” has become something of a fad, in a somewhat perverse way. In the boom of what in Japan is known as Jiko-Keihatsu (whose literal translation is self-enlightenment, self-development, or self-improvement) people aspire to more growth and are encouraged to think that growth is to be achieved by brushing up their knowledge and skills. This chapter explores the significance of Dewey’s perfectionist idea of growth in the age of self-enlightenment and attempts to reclaim this idea of growth in terms of philosophy as a way of life. By doing so, the chapter elucidates the practical nature of pragmatism, exploring a third way, beyond neoliberal conceptions of utility and the potentially reactionary turn into self-cultivation in traditional liberal arts education. The chapter concludes by considering the contemporary significance of Deweyan growth lies in the fact that it opens up a way beyond the self, toward an idea of growth based not upon fear and anxiety but upon trust.
Abstract: In this chapter, Waks examines John Dewey’s concept of growth in Human Nature and Conduct (1922) and its relation to the good. Growth, for Dewey, is not biological or economic but an evolving moral and intellectual responsiveness to changing circumstances. Dewey defines morality as the “growth of conduct in meaning,” linking ethical life to an expanding awareness of action’s conditions and consequences. As Waks shows, Dewey argues that meaning develops through experience as habits are reconstructed in response to feedback. Conduct, unlike mere behavior, involves conscious ends-in-view, and growth occurs when experience expands our meanings – that is, deepens our understanding of how means connect to our ends. Waks distinguishes between proto-meanings in instinctual behavior and the fully articulated meanings made possible by language. Dewey defines the good as the expansion of meaning resulting from the resolution of conflicting impulses into a unified course of action, rejecting moral absolutism in favor of norms shaped by lived experience. Waks concludes by connecting personal growth with democracy as a moral ideal. The good person, in this view, is one who adapts, learns, and creatively responds to new social challenges and freely communicates with others – that is, the person with a democratic personality.
Abstract: This chapter discusses Dewey’s understanding of change developed in Human Nature and Conduct (1922), with particular focus on the impact of evolutionary theory on his thinking. How does Dewey define the connection between individual development and changes in society? And, centrally, what is the role of education therein? Dewey rejects the categorical division between individual and environment underpinning the two common perspectives that change begins in either the individual or the environment. He proposes a third, interactive view of change. Nardo argues in this chapter that Dewey’s “third view” is grounded significantly in his engagement with evolutionary theory. She shows how Dewey rethinks human behavior, ethics, and morality as evolving in relation to the environment rather than as fixed metaphysical principles. Dewey terms this process “growth.” The chapter shows how creating environments for growth, where the formation of intelligent habits is made possible, is central to the work of the teacher. Nardo discusses how schools can be places where albeit not ideal but at least improved circumstances can be imagined and created to direct individual and societal growth, such that the school, for Dewey, is the realm of (admittedly small) revolutions.
The increasing demand for sustainable feed ingredients in aquaculture has driven research into alternative protein sources to replace fishmeal. This study evaluated the nutritional, physiological, and microbiological impacts of housefly (Musca domestica) larvae meal as a replacement for fishmeal in the diets of rainbow trout (Oncorhynchus mykiss). Diets were formulated to replace fishmeal with larvae meal at 50% and 100% inclusion levels. Growth performance, body composition, intestinal health, and gut microbiota were assessed over a 16-week feeding trial. Fish fed larvae meal-based diets exhibited comparable growth metrics, muscle yield, and hepatosomatic index to those fed fishmeal and commercial diets, indicating no compromise in growth efficiency. Intestinal histological examination revealed no diet-induced morphological changes, with all parameters remaining within normal ranges, highlighting the compatibility of larvae meal with fish intestinal health. Analysis of gut microbiota showed a shift toward Firmicutes dominance and increased abundance of Clostridiales in larvae meal-fed fish, suggesting enhanced fermentation activity. Blood chemistry parameters were consistent across dietary groups, supporting the physiological suitability of larvae meal-based diets. These findings demonstrate that housefly larvae meal is a sustainable and nutritionally viable alternative to fishmeal in aquafeeds for rainbow trout. The results underscore its potential to reduce reliance on fishmeal while maintaining fish health and growth performance.
This handbook introduces Human Nature and Conduct, John Dewey's groundbreaking book about moral psychology and moral philosophy, to a new generation. In his classic work, Dewey redefined impulse, habit, and intelligence: not as isolated individual traits, but as socially conditioned factors shaping human thought and action. His ultimate insight is that growth is the only moral good, and that morality is, at its core, a matter of education. Featuring contributions by leading international scholars, this volume presents expert insights into Dewey's unique psychological framework and its far-reaching impact on moral philosophy and education. The book also tackles contemporary moral dilemmas, from environmental protection and healthcare rationing to sexual liberation and religious transformation, demonstrating how Dewey's thought remains as vital today as ever.
Stagnating incomes have been a widespread concern in advanced democracies over the past decades. However, despite a turn towards dynamic frameworks, the consequences of stagnation on political support for the welfare state are still unclear. This study introduces the distinction between ‘absolute’ and ‘relative’ income stagnation – that is, experiencing stagnating incomes over time (without reference to other groups) and in relative comparison to other groups – and explores how they shape citizens’ attitudes towards redistribution. I argue that absolute and relative stagnation have opposite effects on redistributive preferences. Contrary to political economy theories, I expect that low absolute income growth reduces demand for redistribution, because it reduces voters’ ability and willingness to afford welfare state policies. Support for this hypothesis is provided in an empirical analysis that combines novel estimates for absolute and relative income stagnation with longitudinal survey data on redistribution preferences in 14 advanced democracies between 1985 and 2018. The distinction between absolute and relative experiences has broader implications for comparative politics research and might contribute to explain why income stagnation and rising inequality have not led to higher political demand for redistributive welfare policy.
Infants with CHD who undergo cardiopulmonary bypass surgery are at risk of impaired growth and neurodevelopment. However, few studies have thoroughly investigated the risk factors for growth and neurodevelopmental impairments, particularly with respect to the timing of the initial surgical intervention.
Methods:
We retrospectively analysed term singleton infants with CHD who underwent cardiopulmonary bypass surgery at a Japanese tertiary centre between 2015 and 2021. Neurodevelopment was assessed at 18–22 months of age using the Kyoto Scale of Psychological Development. We compared outcomes by CHD type (univentricular [UV] vs. biventricular [BV]) and analysed risk factors for growth impairment (weight and height < tenth percentile) and neurodevelopmental impairment (developmental quotient [DQ] < 85), including birth weight, sex, the type of CHD (UV or BV), and timing of the initial cardiopulmonary bypass surgery (<28 days or ≥28 days).
Results:
Of the 108 eligible children, 29 had UV physiology and 79 had BV physiology. Both groups showed impaired growth, with significantly lower body weights in the UV group. Neurodevelopmental scores (total DQ) were significantly lower in the UV group. Neurodevelopmental impairment (total DQ < 85) was observed in 44/108 (40.7%) children, and after adjustment, UV repair was significantly associated with neurodevelopmental impairment (adjusted odds ratio [OR] 3.11, 95% confidence interval [CI] 1.27–7.65). Timing of the initial cardiopulmonary bypass surgery was not associated with outcomes.
Conclusion:
Infants with CHD in Japan exhibit impaired growth and neurodevelopment at 18–22 months following cardiopulmonary bypass surgery, especially those with UV physiology.
