I contribute to the literature on the growth of public spending in Western economies with a novel mechanism that ties it to the marketization process, i.e. the substitution of home with market production. I argue that a key contributor to the expansion of social spending is the replacement of family-based transfers with public pensions and other public transfer programs. I provide empirical support for this hypothesis by establishing the long-run relationship between government size and marketization, alongside other established determinants of government spending, in a panel of Western economies. I then illustrate a potential mechanism behind the results with a theoretical model in which, as a result of the productivity advantage of the market over the home sector, family-based intergenerational transfers decline unexpectedly, providing a rationale for government intervention in the form of public pensions with a poverty relief component.

The food we eat has a critical impact on human and planetary health. Food systems are responsible for approximately a third of total global greenhouse gas emissions (GHGE). This review summarises studies that have measured dietary GHGE and assessed their associations with various demographic variables. Most studies report dietary emissions at the individual level, but some studies use households as the unit of analysis. Studies investigating individuals estimate dietary intakes using 24-hour dietary recalls, FFQ, diet history interviews, food diaries or other dietary records. Studies investigating households rely on food purchasing data and expenditure surveys. The majority of studies estimate dietary GHGE using process-based life cycle assessments. It is difficult to directly compare emissions estimates between studies at either the individual or household-level due to methodological differences. In general, there are mixed findings with regard to the relationships between various demographic variables and dietary emissions, although older adults generally had higher dietary GHGE than younger adults, and men typically had higher dietary GHGE than women, even when standardising for total energy intake. This review may be useful in informing and targeting policies and interventions to reduce GHGE of dietary intake.

The secondary metabolites of several plant species, particularly sesquiterpenic lactones (SLs) have been studied by different research groups for over 30 years. This group of metabolites presents numerous biological activities such as antibacterial, antiviral, antiulcer, cell proliferation inhibitor, and oocyte activator with participation in exocytosis processes. This study aims to assess some sperm parameters in epididymal gametes of Chichilla lanigera exposed to increasing concentrations (0 to 2 mM) of DhL for various incubation times from 10 to 40 minutes. We determined the participation of different cell signalling pathways in the induced acrosome reaction. Our results showed an alteration in the progressive motility pattern and cell viability depending on DhL concentration and exposure time of gametes. When analyzing acrosomal status, higher percentages than the negative control were obtained in all tested doses. Both isolated and joint inhibition tests of PKA and phospholipases (PLC and PLA2) showed a greater participation of PI-PLC. This is the first report concerning the effects of this lactone on the medium of sperm incubation. Consequently, further studies will be necessary to determine the molecular implications of this lactone on the fertilizing potential of the sperm.

Since the end of the Cold War, democracies have sought to create a range of normative and international legal standards intended to reduce the frequency, and legitimacy, of coups. The rise of the anti-coup norm has led to the isolation and punishment of numerous coup-created governments, and evidence suggests it has helped reduce the frequency of coup attempts. However, the norm is contested, and coup leaders often find that the international condemnation they face is countered by quiet acquiescence or active support by international allies. This paper examines the politics of norm contestation around the anti-coup norm by considering the international response to the 2021 coup in Myanmar. It introduces the concept of ‘norm waverers’ and illustrates how committed norm promoters and norm resisters often try to persuade norm waverers – in this case exemplified by ASEAN (the Association of Southeast Asian Nations) – to join their respective camps. International pressure after the Myanmar coup induced ASEAN to take steps to enforce the anti-coup norm. But these ultimately reflected a concern with its own reputation and credibility, rather than any underlying institutional commitment to the norm itself. The result was a shallow institutionalisation of the anti-coup norm.

As countries transition from fossil fuels to renewable energy, impacts on wildlife, particularly avian species, have become a concern. In Kenya, the effects of human-made infrastructure such as power lines and wind turbines on birds have been overlooked. To prevent further loss of biodiversity, it is necessary for infrastructure development policies to consider these impacts on birds. We aim to identify gaps in current policies by analysing the intersection of wildlife conservation and power-line infrastructure development in Kenya. Through content analysis, we evaluate the effectiveness of existing wildlife protection and energy-related policies and identify strengths and weaknesses to highlight areas for improvement. Our analysis reveals that current policies neglect threats posed by power lines and other infrastructure to birds. This oversight points to challenges such as a lack of awareness among policymakers and stakeholders and a lack of legal obligation for energy institutions to implement mitigation measures; conservationists may also face conflicts with those responsible for electricity distribution. Addressing these policy gaps is essential for effective wildlife conservation and sustainable development. This paper underscores the need to integrate wildlife conservation considerations into energy infrastructure planning to mitigate adverse impacts on avian species.

We prove that any bounded degree regular graph with sufficiently strong spectral expansion contains an induced path of linear length. This is the first such result for expanders, strengthening an analogous result in the random setting by Draganić, Glock, and Krivelevich. More generally, we find long induced paths in sparse graphs that satisfy a mild upper-uniformity edge-distribution condition.

An examination of the apparent gap – familiar in many branches of philosophy – between ‘the facts’ and ‘values’, focusing especially on Sam Gamgee’s perception of ‘Earendil’s Star’ and the real nature of ‘the planet Venus’: Is it possible to trust in the awe and admiration we may feel towards ‘the heavens’ in the light of current astronomical theory about the wider world? How can humane values, including love of beauty, survive in an inhumanly indifferent world? Can obvious fictions have more than allegorical significance? Must we rely on fictions to survive as humane creatures, or may those seeming fictions, and our initial emotional response, provide true guidance to the way things are, and how we might be?
