To estimate the within-households association between change in income over time and food purchases in a national panel of households. The need to shift towards healthy and sustainable diets is widely recognized, thus the importance of identifying the factors that influence food purchase decisions.
Design:
Longitudinal observational study; for each of the 33 food items queried, we ran a conditional logistic fixed-effect regression model to evaluate the association between change in income per-capita and food purchases (yes/no) during the past week, adjusted by covariates.
Setting:
Mexican Family Life Survey
Participants:
6,008 households that participated in the survey for at least two of the three available waves of study (2002, 2005, and 2009).
Results:
Within-households, the odds ratio (95% CI) of purchasing the food in the past week for an increase in 1 SD of income was 1.09 (1.02, 1.16) for rarer fruits (other than bananas, apples, and oranges); 1.11 (1.04, 1.18) for beef; 1.06 (1.00, 1.13) for canned tuna/sardines; 1.09 (1.02, 1.18) for fish/shellfish; 1.08 (1.02, 1.16) for discretionary packaged products, and 1.15 (1.08, 1.23) for soft drinks. There were some differences by urban/rural area or SES; mainly, those with lower SES had increased odds of purchasing the food item in more cases (10 out of 33 food items).
Conclusions:
households’ income growth can have mixed effects on the healthiness and sustainability of food purchases. Public policies to improve the food environment and nutrition education are necessary to enhance the positive and counteract the negative effect of income.
Background: The efficacy and safety of lecanemab have previously been evaluated in the Phase 3 randomized clinical trial, Clarity AD (NCT03887455). Methods: A Markov cohort model was developed to estimate the cost-effectiveness of lecanemab versus standard of care (SoC) in patients with mild cognitive impairment (MCI) or mild dementia due to Alzheimer’s disease (AD), with confirmed beta-amyloid (Aβ) pathology, from a Canadian societal perspective. Health states were determined by Clinical Dementia Rating-Sum of Boxes (CDR-SB) scores. Transitions between health states during month 0-18 were estimated from Clarity AD. Beyond month 18, relative efficacy for lecanemab in the form of the hazard ratio for time-to-worsening of CDR-SB was applied to literature-based transition probabilities. The model included the effects of lost productivity and impact on carer health-related quality of life. Results: The incremental cost-effectiveness ratio (ICER) for lecanemab vs SoC was estimated to be CAD 62,751 per QALY gained. The probability that lecanemab was cost-effective at a threshold of CAD 100,000 was estimated to be 88.5%. Conclusions: Lecanemab represents a cost-effective option for the treatment for early AD from the Canadian societal perspective. The results of this analysis can be used to inform clinical and economic decision making.
This work reports the X-ray powder diffraction (XRPD) data recorded at room temperature (293 K) of dibromidodioxido-[(4,4′-di-tert-butyl)-2,2′-bipyridine]molybdenum(VI). The analysis of the powder diffraction pattern led to an orthorhombic united cell with parameters a = 17.9205(23) Å, b = 13.4451(16) Å, c = 18.1514(19) Å, V = 4,373.5(11) Å3, and values of Z = 8 and Z’ = 2. The crystal structure of this material corresponds to the structure of entry IFUJEC of the Cambridge Structural Database (CSD), determined at 90 K. The excellent Rietveld refinement, carried out with General Structure and Analysis Software II (GSAS-II), showed the single-phase nature of the material and the good quality of the data. This material was also characterized by elemental analysis, UV–vis, Fourier transform infrared spectroscopy (FTIR), and proton nuclear magnetic resonance (1H-NMR) techniques.
The chapter argues that post-1945 international human rights law cannot be understood without accounting for the interwar period and some core elements of human rights discourse which existed at the time. Whereas classical histories of human rights have focused on genealogy and teleology to spell out the advent of rights universalism, more recent work has anchored the origins of human rights in national political communities. Accounting for these new historiographies, this chapter distinguishes between nineteenth-century human rights discourse and post–Second World War international human rights law. Elements of the former and antecedents of the latter can be found in the interwar period, in particular in the legal regimes for the protection of refugees and minorities. Although it analyses the two regimes separately, it articulates their points of convergence and situates them in the context of rising nationalism and the advent of the individual as a subject of international law.
The nature and extent of interactions between the distant regions and cultures of Mesoamerica remain open to much debate. Close economic and political ties developed between Teotihuacan and the lowland Maya during the Early Classic period (AD 250–550), yet the relationship between these cultures continues to perplex scholars. This article presents an elaborately painted altar from an elite residential group at the lowland Maya centre of Tikal, Guatemala. Dating to the fifth century AD, the altar is unique in its display of Teotihuacan architectural and artistic forms, adding to evidence not only for cultural influence during this period, but also for an active Teotihuacan presence at Tikal.
Written accounts suggest there were major changes in agricultural practices in Anatolia as the region switched between Roman, Byzantine, Arab and Turkic control, yet archaeological evidence of these changes is offered only on a site-by-site basis. This article presents the first synthesis of archaeobotanical, palynological and zooarchaeological evidence for changes in plant and animal husbandry in Anatolia through the first and second millennia AD. Available data indicate a minimal role of climate change in agricultural shifts but offer evidence for substantial changes towards short-term-return agricultural strategies in response to declining personal security, changing patterns of military provisioning and distinct taxation regimes.
Wedderburn’s final pamphlet, Address to the Lord Brougham and Vaux, contributed to the early nineteenth-century political “war of representation” about whether Black people in the West Indies would be willing to work for wages after emancipation. Although seeming to reiterate the proslavery claim that enslaved people in the West Indies had better living conditions than European wage laborers, Wedderburn’s vision of dwelling on the land outlined a nuanced, speculative decolonial future. The Conclusion finally argues that narratives of the Romantic revolutionary age should include Black abolitionist geographies, a revolution cultivated on common land with pigs, pumpkins, and yams.
As he rose to leadership of the Spencean Philanthropists in 1817, Robert Wedderburn wrote and published six issues of Axe Laid to the Root, an inexpensive weekly periodical for working-class readers. Axe Laid to the Root instructed its white audience about the radical potential of African-Jamaican land and food-based liberation. The provision grounds, plots set apart from the plantation for enslaved people to grow their own food, were a source of resistance to plantation capitalism, providing food sovereignty and communal identity. The ecological knowledge of the Jamaican Maroons was another source of resistance to plantation economies. Finally, Wedderburn’s writing in “cheap” periodicals aspired to cultivate a transatlantic alliance between the English lower classes, the colonized Irish, and free and enslaved people in Jamaica. The chapter concludes by discussing George Cruikshank’s The New Union Club, which features Wedderburn as a central figure within abolitionist circles.
Horrors of Slavery announced an abolitionist politics unacknowledged by Romantic-era antislavery activists: place-based, self-liberation initiated and led by Black women. Reworking the abolitionist figure of the sorrowful, enslaved Black mother, Wedderburn celebrated his mother, Rosanna, who demanded that his enslaver father manumit him, and championed his grandmother, Talkee Amy, as a higgler and obeah woman who “trafficked on her own account.” Similar freedom practices are then traced throughout The History of Mary Prince. Prince’s repeated petit marronage demanded enslavers’ acknowledgment of her kinship with her parents and husband. As a higgler, like Talkee Amy, Prince used the produce from the provision grounds to assert freedom in fugitive markets. Wedderburn and Prince’s life narratives brought stories of Black women’s place-based freedom practices to a white audience.
This chapter moves backward in time to trace the Maroons’ decolonial relationship with the environment, starting with Queen Nanny, a leader in the First Maroon War and a present-day National Hero of Jamaica. Narratives of Nanny’s warfare against the British noted that her fight included growing pumpkins in the rugged Blue Mountains. The chapter then turns to a critically neglected Romantic-era text, R. C. Dallas’s History of the Maroons. Although primarily a military history, Dallas repeatedly admired the Maroons’ communal “superabundance.” Similarly, J. G. Stedman’s Narrative of a Five Years’ Expedition, accompanied by William Blake’s illustrations, described Maroon settlements as viable, sustainable societies that were notable alternatives to plantation capitalism. The Maroons’ agricultural and culinary “superabundance,” documented by Dallas, Stedman, and Blake alike, suggests a Romantic-era ecological critique rooted in communal decolonial practices, which supplements the Romantic figure of the solitary walker who critiques society by communing with nature.
Wedderburn’s view of Black-led abolition was further outlined in his life narrative, Horrors of Slavery. The narrative initially emerged as a series of letters to a working-class periodical, Bell’s Life in London, after the editor had questioned whether plantation owners ever enslaved their own mixed-race children. The question prompted Wedderburn to share his life story, in which he represented himself as a “product” of plantation slavery and testified to his father’s moral depravity as a “slave-dealer.” Although the letters prompted threatening replies from his half-brother, Andrew Colvile, Wedderburn republished the Bell’s Life letters as a pamphlet that was sold by ultra-radical booksellers in London. Horrors radically tracked Wedderburn’s life from slavery on a Jamaican plantation to his harsh sentence of solitary confinement in an English prison for blasphemous libel, making it an essential supplement to more commonly studied Romantic-era slave narratives, such as Equiano’s Interesting Narrative.
In his Journal of a West India Proprietor, Matthew Lewis documented numerous encounters with the people he enslaved. Guided by Wedderburn’s argument that the provision grounds must be guarded “above all” for Black liberation, this chapter argues that tensions over provision grounds permeated Lewis’s encounters. After granting an additional day per week on the provision grounds as “a matter of right,” Lewis documented that enslaved people were growing poisons, unleashing fires, harboring crowds of destructive livestock, and providing sustenance for self-liberated Black people. Despite noticing these dangers, Lewis wrote to William Wilberforce detailing a plan for emancipating the people he enslaved by giving them his plantation, a proposal feared to be “dangerous to the island.” Lewis’s Journal recorded that his plantations were undermined, not by overt rebellion, but rather by the success of the Black ecological project: The botanical and animal ecologies of the provision grounds were anticipatory abolitionist commons that would be drawn upon in the coming emancipation.
This chapter argues that the provision grounds continued to trouble the Victorian imagination. The radical nature of the provision grounds emerged vividly during and after the abolition of slavery in 1834 when newly freed Black people challenged the plantocracy by staying put on their communal provision grounds. Both antislavery and proslavery writers developed strategies for displacing Black Jamaicans from their land. Abolitionist Joseph Sturge, for example, recommended importing provisions from Haiti to weaken Jamaica’s internal markets and make workers dependent on wages. Thomas Carlyle’s notorious “Discourse” seethed with racist rage focused on “Quashee” surrounded by pumpkins, a synecdoche for independent, agriculturally successful Black people. In Carlyle’s essay, the planter picturesque becomes an abolitionist grotesque of “waste fertility,” an environment of seemingly out-of-control plants and animals swarming around free Black people unwilling to participate in Britain’s wage labor economy. Carlyle’s coinage of “waste fertility” inadvertently illustrated the Black geographies championed by Wedderburn.
Robert Wedderburn was deeply influenced by his enslaved mother and grandmother, who raised him in Jamaica. After migrating to London, he became a key figure in ultraradical circles and was prosecuted by the British government for blasphemous libel. Wedderburn’s vision for abolition from below sought to forge a transatlantic alliance between English agrarian radicals and enslaved people in the Caribbean. Wedderburn’s influence was documented in Robert Cruikshank’s caricature, A Peep in the London Tavern, which depicted him challenging the proto-socialist Robert Owen. After a review of existing scholarship that places Wedderburn within ultraradical circles or focuses on his mixed-race identity, the Introduction argues that understanding Wedderburn’s advocacy for land-based insurrection requires dialogue with scholarship in Black geographies. Wedderburn’s insights about place-based resistance to slavery are then illustrated in a reading of James Hakewill’s Picturesque Tour of the Island of Jamaica.
