This study examined changes food and drink purchasing during the first 3 months of the COVID-19 pandemic in England, and if changes varied by population subgroups.
Design:
We investigated changes in take-home food and drink purchasing and frequency of out-of-home (OOH) purchasing using an interrupted time series analysis design. The start of pandemic restrictions (the intervention) was defined as 16 March 2020, when first announced in the UK.
Setting:
London and the North of England.
Participants:
1245 households reporting take-home and 226 individuals reporting OOH purchases between January 2019 and mid-June 2020 from the GB Kantar Fast Moving Consumer Goods Panel.
Results:
The marginal mean estimate of total take-home energy purchased was 17·4 % (95 % CI 14·9, 19·9) higher during the pandemic restriction period compared with the counterfactual. Increases of 35·2 % (95 % CI 23·4, 47·0) in take-home volume of alcoholic beverages and 1·2 % (95 % CI 0·1, 2·4) in foods and drinks high in fat, salt and sugar were observed. Reductions in purchased energy from fruit and vegetables (–7·3 %, 95 % CI –10·9, –3·6), ultra-processed foods (–4·0 %, 95 % CI –5·2, –2·8) and in OOH purchasing frequency (–44·0 %, 95 % CI –58·3, –29·6) were observed. Changes in chocolate and confectionery, soft drink and savoury snack purchases levelled off over time. Changes in all studied outcomes varied by sociodemographic characteristics and usual purchasing.
Conclusions:
Pandemic restrictions were associated with positive and negative changes in food and drink purchasing, which differed by individual characteristics. Future research should ascertain if changes persist and translate into changes in health.
This article considers a significant but overlooked set of policy developments in the latter half of the twentieth century: the extension of collective bargaining rights to most health care workers, many of whom were formally excluded for three decades under the 1947 Taft-Hartley amendments. Drawing on primary sources including archival records, an exhaustive review of congressional testimony, and rulings from the quasijudicial agency governing private sector industrial relations, this article shows that health care workers did so in two interrelated processes. First, in coordination with the civil rights movement, workers mobilized and used both disruptive and legal social movement tactics. Second, in doing so they drew the state into and revealed its position in the collective bargaining process between workers and health institutions, facilitating what is conceptualized as cross-domain policy feedback. Cross-domain policy feedback occurs when a policy in one domain (e.g., public health spending) influences the politics of a policy in a seemingly separate one (e.g., labor and employment relations). Such effects, this article suggests, are likely to occur when a policy is relatively large in scale, implicates actors with a diverse set of interests, and offers significant ambiguity and discretion in its implementation. Empirically, this article is the first to chart the institutionalization of collective bargaining rights for health care workers, among the largest group of private sector employees in the postindustrial economy. It also offers a new theoretical and conceptual framework through which to study the ways by which public policies reshape political dynamics—an enduring research agenda for students of American politics and policy.
Orthorexia has been widely studied, but recently, a new conceptualisation was proposed to distinguish its healthy characteristics from its pathological ones. The objective of this study was to differentiate healthy orthorexia (HeOr) from orthorexia nervosa (OrNe) by exploring their sociodemographic, psychological, health and dietary characteristics using comparative and correlational statistical methods.
Design:
Cross-sectional analysis. Participants completed an online, self-administered questionnaire assessing their sociodemographic characteristics, orthorexia, exercise dependence, personality, health anxiety, food choice motives, emotional competences and eating disorders (ED).
Setting:
Data were collected between May 2021 and September 2022.
Participants:
1515 French females (meanage = 37·67). Responses from men were excluded.
Results:
While OrNe was mainly associated with weight control motives in food choices (r = 0·42), HeOr was more strongly correlated with natural content (r = 0·60) and health motives (r = 0·49). In relation to exercising, OrNe showed its highest association with weight control (r = 0·41). Health anxiety was more strongly associated with OrNe than with HeOr. Both OrNe and HeOr were related to diet adherence and regular exercise, but the association was stronger for the latter. Orthorexia scores, mainly OrNe, were higher in participants at the risk of ED. Participants who were afraid to gain weight showed higher OrNe scores.
Conclusions:
HeOr seems to be part of a healthy lifestyle in general. In contrast, OrNe falls into the category of an ED and is associated with more problematic psychological functioning. Particular attention should be given to individuals who are beginning to control and reduce their food intake to prevent them from developing OrNe.
Vaccination is the most important method to control the spread of SARS-CoV-2, the virus that causes COVID-19, and vaccination is key to this goal. This paper highlights considerations for policy development around vaccination attestation and proof requirements, specifically in rural Appalachia. Migrant and immigrant farmworkers are integral to the food and goods supply chain globally; they have been disproportionately impacted by COVID-19, therefore these policies need to take extensive precautions for farmworkers to systematically and easily comply with vaccination status submission procedures. In this paper, we present steps to equitably manage and implement vaccine mandates: (1) Develop and establish policies to support safe workplace standards for everyone, including vaccination policies; (2) Utilize equitable methods to collect vaccine verification; (3) Use effective and inclusive methods to implement the policies by using these techniques; (4) Integrate key populations to develop and strengthen policies to improve health equity.
There is a growing awareness that diversity, health equity, and inclusion play a significant role in improving patient outcomes and advancing knowledge. The Pediatric Heart Network launched an initiative to incorporate diversity, health equity, and inclusion into its 2021 Scholar Award Funding Opportunity Announcement. This manuscript describes the process of incorporating diversity, health equity, and inclusion into the Pediatric Heart Network Scholar Award and the lessons learned. Recommendations for future Pediatric Heart Network grant application cycles are made which could be replicated by other funding agencies.
Research in Roman interior design and wall painting has undergone two major shifts in the past century. The first, in the 1980s, steered away from the tradition of purely art historical studies that had elucidated the basic principles of artistic developments, iconographies, and pictorial programs. Instead, researchers focused on the Roman house as a social space, with private and public zones inhabited by individuals of different social standing. The second shift, occurring in the new millennium, saw researchers returning to the decoration of the house; however, they were now more intrigued by the cognition and reception of the paintings and how they were conceived to create atmospheres, mnemonic paths, and impressions on their viewers. Simultaneously, important insights into the often-multifunctional use of space were provided by finds analysis.
The accepted approach of competition law to non-horizontal mergers, largely based on the Chicago School of Antitrust Law and Economics paradigms, is criticized on both sides of the Atlantic as too lenient, disregarding developments of economic theory, and no longer adequate in the reality of the digital economy. Current economic research confirms the legitimacy of fears about the effects of non-horizontal concentrations that were raised before the Chicago School put them into doubt. The disbelief in the accuracy of the former US non-horizontal mergers policy resulted in the Federal Trade Commission and the Antitrust Division of the Department of Justice adopting new Vertical Merger Guidelines. The changes introduced were considered insufficient, which led to the unilateral repeal of the guidelines by the FTC and the start of work on new guidelines introducing a stricter approach. The new U.S. 2023 Merger Guidelines introduced far-reaching changes taking into account the modern views of economists and empirical research on vertical mergers. Comparatively, the EU Commission’s Non–Horizontal Merger Guidelines still do not fully correspond to what empirical research and contemporary economic theories say about the possible effects of vertical mergers. Thus, the revision of the EU guidelines seems necessary.
Static analysis of logic programs by abstract interpretation requires designing abstract operators which mimic the concrete ones, such as unification, renaming, and projection. In the case of goal-driven analysis, where goal-dependent semantics are used, we also need a backward-unification operator, typically implemented through matching. In this paper, we study the problem of deriving optimal abstract matching operators for sharing and linearity properties. We provide an optimal operator for matching in the domain $\mathtt{ShLin}^{\omega }$, which can be easily instantiated to derive optimal operators for the domains $\mathtt{ShLin}^2$ by Andy King and the reduced product $\mathtt{Sharing} \times \mathtt{Lin}$.
The quest for corporate accountability remains unabated in the business and human rights (BHR) field. This paper examines the role of multinational corporations (MNCs) and Business Interest Associations (BIA) as entrepreneurs, antipreneurs and saboteurs in setting human rights standards. Through this conceptualization, this paper argues that corporate accountability remains elusive because of corporate actors’ normative power and influence in the BHR norm contestation. It attributes corporate actors’ influence in the norm contestation to the UN multistakeholder design that sees nonstate actors as partners and stakeholders in setting global human rights standards. This article then argues that to force a norm change in the BHR field, there is a need to rethink the BHR governance model. Corporate actors must be reconceptualized as ‘regulated individuals’ during norm discussions and standard-setting processes.
In this essay, I use Martin Luther King Jr.'s “Letter from Birmingham Jail” to open questions about international order and disorder. The idea of order is central to modern discourse on international politics, but the concept is often ill defined and ambiguous. King's ideas clarify three issues: First, is order understood as an objective condition of a system or a political judgment about its suitability for social life? Second, does compliance with law lead naturally to order? And third, is order always preferable to disorder? The way King answers each question is somewhat different than the conventional wisdom in international relations. IR scholars typically assume that international order is a universal good and that compliance with law enhances it. King highlights the gap between order as defined by the authorities in Alabama and his own lived experience. I use the difference to map the terrain of scholarship on international order and disorder and to draw implications for concepts, research methods, and political judgment.
Scholarly and practitioner interest in authentic leadership has grown at an accelerating rate over the last decade, resulting in a proliferation of publications across diverse social science disciplines. Accompanying this interest has been criticism of authentic leadership theory and the methods used to explore it. We conducted a systematic review of 303 scholarly articles published from 2010 to 2023 to critically assess the conceptual and empirical strengths and limitations of this literature and map the nomological network of the authentic leadership construct. Results indicate that much of the extant research does not follow best practices in terms of research design and analysis. Based on the findings obtained, an agenda for advancing authentic leadership theory and research that embraces a signaling theory perspective is proposed.
One of the problems with the problem of world order is that what makes for order within societies is often precisely what makes for disorderly relations between them. I argue in this short essay that many of the problems with the problem of world order arise from assumptions that are widely shared within a discipline where the language of power and interest dominates and where a view of states as “like units” permeates. With more emphasis on values and visions of the good life, and acceptance that the ontological foundation of IR is difference rather than sameness, the debates about the problem of world order would take on a different form. The essay adapts the work of Hedley Bull and introduces the concept of “resilience-governance” to distinguish between resilience as a practice of self-governance taking place within ordering domains and resilience as a practice of “diversity-governance” taking place between ordering domains. The combination of the two allows for a bifocal view into how practices of resilience as self-governance may produce order within individual domains but will at the same time increase diversity and difference between the ordering domains, hence making the practices of resilience as diversity-governance much more challenging.
School-based interventions encouraging children to replace sugar-sweetened beverages with water show promise for reducing child overweight. However, students with child food insecurity (CFI) may not respond to nutrition interventions like children who are food-secure.
Design:
The Water First cluster-randomised trial found that school water access and promotion prevented child overweight and increased water intake. This secondary analysis used mixed-effects regression to evaluate the interaction between the Water First intervention and food insecurity, measured using the Child Food Security Assessment, on child weight status (anthropometric measurements) and dietary intake (student 24-h recalls, beverage intake surveys).
Setting:
Eighteen elementary schools (serving ≥ 50 % children from low-income households), in which drinking water had not been previously promoted, in the San Francisco Bay Area.
Participants:
Students in fourth-grade classes (n 1056).
Results:
Food insecurity interacted with the intervention. Among students with no CFI, the intervention group had a lower prevalence of obesity from baseline to 7 months (–0·04, CI –0·08, 0·01) compared with no CFI controls (0·01, CI –0·01, 0·04) (P = 0·04). Among students with high CFI, the intervention group had a pronounced increase in the volume of water consumed between baseline and 7 months (86·2 %, CI 21·7, 185·0 %) compared with high CFI controls (–13·6 %, CI –45·3, 36·6 %) (P = 0·02).
Conclusions:
Addressing food insecurity in the design of water promotion interventions may enhance the benefit to children, reducing the prevalence of obesity.
This study closely replicates Wong, Zhao, & MacWhinney (2018), who found that cognitive linguistics–inspired instruction (i.e., schematic diagram feedback) demonstrated a superiority effect over traditional instruction (i.e., rule and exemplar feedback or corrective feedback) on the translation test but not the cloze test. While the original study adopted the null hypothesis testing approach, the current study adopted Bayesian mixed effects logistic models to investigate how different variables might affect the learnability of prepositions among 81 Chinese-speaking learners of English. The research design, materials, and procedure are nearly identical to those of the original study except for an added delayed posttest. Our findings are generally consistent with the results reported in the original study, indicating that the cognitive linguistics–informed instruction demonstrates superiority effect. Furthermore, these positive learning outcomes persist over time, as evidenced by the results of the delayed posttest.
Losses due to wake interactions between wind turbines can significantly reduce the power output of wind farms. The possibility of active flow control by wake deflection downstream of yawed horizontal-axis wind turbines has motivated research on the fluid mechanics involved. We summarize the findings of a wind tunnel study (Bastankhah & Porté-Agel, J. Fluid Mech., vol. 806, 2016, pp. 506–541) of the flow associated with a yawed model wind turbine, and the insights and modelling developments that have followed this important study.
Discussions of the liberal international order, both inside and outside the academy, tend to take its necessity and desirability for granted. While its specific contours and content are left somewhat open in such debates, the idea that this international order is essential for global peace and stability is left largely unquestioned. What is more, the potential loss or end of this order is often taken to mean a return to anarchy, chaos, and disorder. In this essay, I question the presumed necessity and desirability of the liberal international order that most discussions of it seem to share. By rethinking the international order as processual, emergent, and grounded in the social and political contexts that shape its constitution and operation, I suggest that fears about the crisis of international order are less about international order itself and more about the loss of a specific order. This specific order, I argue, constituted in part through processes of racialization, is not so much a rules-based order of sovereign equality but rather an international order of White sovereignty that secures the domination and rule of some over others, of Whiteness over non-Whiteness. Recognizing the role of White sovereignty in the contemporary international order points toward a need to take seriously calls for abolition. Rather than signifying a return to chaos and disorder, the prospect and promise of abolition represents a call to break free from the constraints of the present order and reach into an as-yet-unimaginable future.
The rise of populist parties in Europe has generated an enormous amount of academic literature. Previous research has thoroughly examined the factors contributing to the electoral success of populist parties. Surprisingly, very little attention has been paid to the role of decentralization, one of the most widespread forms of governance in the world. This paper aims to fill this gap by presenting a theoretical and empirical account of the effect of decentralization on the electoral fortunes of populist parties in Europe. Using aggregated data from election results in 30 European countries, this paper puts competing hypotheses to the test. I argue that the mechanism linking decentralization and populist parties’ national election results is, in fact, indirect and depends on the existence of a regional tier of government. Results suggest that having representation in subnational parliaments plays a significant role in the national success of populist parties, and this effect is contingent on the degree of regional authority.
Since its publication in 2010, the paper by Schmid (J. Fluid Mech., vol. 656, 2010, pp. 5–28) has wielded considerable influence, an impact we examine here. That seminal work introduced dynamic mode decomposition, a method for performing flow-field spectral analysis of snapshot sequences of data. As a data-driven approach aimed at uncovering spatial and temporal patterns or modes within datasets, its applicability has extended far beyond fluid mechanics, reaching into a wide array of fields.
We aimed to analyse the evolving trends in macronutrient intake and dietary composition among Korean children and adolescents over a 10-year period.
Design:
We utilised cross-sectional data from the Korean National Health and Nutrition Examination Survey (KNHANES) spanning the years 2010–2020. Overall, the study included 11 861 participants aged 6–18 years who completed the 24-h dietary recall survey. Subsequently, we assessed trends in energy consumption and macronutrient intake across population subgroups, including age, sex and obesity status. Survey-weighted linear regression was employed to determine the β coefficient and P-value for trends in dietary nutrient consumption, treating the survey year as a continuous variable.
Setting:
KNHANES from 2010 to 2020.
Participants:
11 861 children and adolescents aged 6–18 years.
Results:
Total energy intake significantly decreased across the 10-year survey period, with a corresponding decline in the percentage of energy intake from carbohydrates. Conversely, the proportion of energy intake from fat increased during the same period. Subgroup analysis revealed changes in the composition of energy intake across age, sex and obesity status, with a consistent increase in total fat intake observed across all subgroups. Upon analysing data on dietary fibres, total sugars and fat subtypes intake, we found insufficient dietary fibre intake and increased intake of all fat subtypes.
Conclusions:
This study underscores the gradually changing dietary intake patterns among Korean children and adolescents. Our findings revealed that these transitions in dietary nutrient consumption may pose potential risks of diet-related diseases in the future.
This article examines three high-profile House ethics cases involving former Speakers James Wright (1988–1989) and Newt Gingrich (1994–1997) and former House Majority Leader Tom DeLay (1997–2004). The analysis of the filing and disposition of charges in the three cases provides some evidence for the “politics-by-other-means” or “partisan-ethics-wars” framework that is sometimes used to evaluate ethics enforcement in Congress. However, the analysis also provides evidence of bipartisan agreement both in the ethics committee and on the floor. The article highlights the areas of bipartisan consensus and the principles behind that consensus. In paying attention to the content of the cases, it also highlights an important change in ethics investigations over time, specifically an increase in “political gain” cases. The article thus calls attention to aspects of House ethics investigations that are undervalued and inadequately addressed by the partisan-ethics-wars framework.
