This study compared red meat, white meat and vegetable consumption before, during and after COVID-19 pandemic among older adults in regional China. Data were collected from urban individuals aged 60+ years in Nanjing municipality in 2018, 2021 and 2023. Differences in food intake frequencies between participants and survey years were examined. Logistic regression models were employed to identify influencing factors of meat, and vegetable consumption. Totally, 13 792 participants were analysed, with 4355, 4622 and 4815 from 2018, 2021 and 2023 surveys, respectively. The mean weekly intake frequency (sd) in 2018, 2021 and 2023 was, separately, 3·85 (sd 2·83), 3·21 (sd 2·90) and 4·71 (sd 3·94) for red meat; 1·38 (sd 1·21), 2·08 (sd 1·90) and 2·73 (sd 2·55) for white meat; and 10·98 (sd 4·84), 10·00 (sd 5·04) and 10·34 (sd 5·04) for vegetable. Moreover, 23·2, 32·6 and 52·3 % of participants met the recommendation for meat intake, while 53·7, 46·8 and 49·6 % reached vegetable intake recommendation before, during and after COVID-19 pandemic, respectively. Meat intake was positively associated with education, marital status and drinking, but negatively associated with age. Additionally, education and marital status were in negative relation to vegetable consumption, while smoking and drinking were positively associated with vegetable intake. The older residents consumed less red meat and vegetable but more white meat during COVID-19 pandemic, and their consumption levels of meat and vegetable went up after the pandemic. These findings highlight the need for targeted interventions to support older adults’ dietary habits during emergency events.

In this article, for general curves $(t,\gamma (t))$ satisfying some suitable curvature conditions, we obtain some $L^p(\mathbb {R})\times L^q(\mathbb {R}) \rightarrow L^r(\mathbb {R})$ estimates for the bilinear fractional integrals $H_{\alpha ,\gamma }$ along the curves $(t,\gamma (t))$, where

$$ \begin{align*}H_{\alpha,\gamma}(f,g)(x):=\int_{0}^{\infty}f(x-t)g(x-\gamma(t))\,\frac{\textrm{d}t}{t^{1-\alpha}}\end{align*} $$

$\alpha \in (0,1)$

$L^p(\mathbb {R})\rightarrow L^q(\mathbb {R})$

$(t,\gamma (t))$

$$ \begin{align*}I_{\alpha,\gamma}f(x):=\int_{0}^{\infty}\left|f(x-\gamma(t))\right|\,\frac{\textrm{d}t}{t^{1-\alpha}}.\end{align*} $$

The history of sugar is that of a commodity that has played a central and contested role in the development of global agro-industrial capitalism. In my introduction to this “Suggestions and Debates” collection, the theoretical underpinnings of The World of Sugar will be explained. Reference is made to the agenda of the Commodity Frontiers Initiative, which was published in the Journal of Global History in 2021, and of which I was a co-author. Inspired by the work of Friedmann and McMichael, a key element of this agenda is the notion of successive commodity regimes, separated by systemic frictions and phases of intense innovation to overcome them. Moreover, the argument is made that The World of Sugar can be read as an invitation to explore new directions in global labour history. My introduction concludes with an exhortation to overcome the limitations of single-commodity histories and to give more attention to the agency of workers in shaping the trajectories of global capitalism.

We study the moduli stacks of slope-semistable torsion-free coherent sheaves that admit reflexive, respectively, locally free, Seshadri graduations on a smooth projective variety. We show that they are open in the stack of coherent sheaves and that they admit good moduli spaces when the field characteristic is zero. In addition, in the locally free case we prove that the resulting moduli space is a quasi-projective scheme.

This study aims to analyze the effect of internal pay attributions on employees’ perceived organizational support (POS). Furthermore, it examines the pathway through which these pay attributions influence POS by analyzing the mediating effect of pay level satisfaction. Based on survey data from 695 employees, the results show that commitment-focused pay attributions are positively and directly related to POS, and also indirectly related to it through the mediated effect of pay level satisfaction. Regarding control-focused pay attributions, while getting the most out of employees’ pay attribution is only directly and negatively related to POS, the cost-reduction HR strategy pay attribution is only indirectly and negatively related to POS through pay level satisfaction. This study is relevant because it provides a more in-depth understanding of how employees’ perceptions of the intentions behind pay decisions can influence how they assess both the organization and the outcomes they receive.

We establish a Quillen equivalence between the Kan–Quillen model structure and a model structure, derived from a cubical model of homotopy type theory (HoTT), on the category of Cartesian cubical sets with one connection. We thereby identify a second model structure which both constructively models HoTT and presents $\infty $-groupoids, the first example being the equivariant Cartesian model of Awodey–Cavallo–Coquand–Riehl–Sattler.

Previous studies demonstrated that ultra-processed foods (UPF) affect overall diet quality. However, none have yet examined this relation across different age groups in Brazil. This study assessed the relationship between diet quality and the consumption of UPF in a Brazilian population according to age groups. This was a cross-sectional study that analysed food consumption data from 46 164 Brazilians aged ≥10 years who participated in the 2017–2018 National Dietary Survey. Food and beverages consumed were recorded by two 24-h recalls. All food items were classified as UPF or non-UPF according to the Nova system. Diet quality was evaluated using nutritional density and the prevalence of inadequate nutrient consumption, according to the quintiles of energy contribution of UPF. The association between diet quality and UPF consumption was evaluated by linear and Poisson regressions, with adjustment for sociodemographic variables, stratified by age groups (adolescents, adults and older adults). The consumption of UPF increased the densities of carbohydrates, free sugar, saturated fat and Na and decreased the densities of proteins, fibres and potassium in three age groups. Higher prevalence ratios (PR) of inadequate consumption of free sugar and fibre among the lower and higher quintiles of energy contribution of UPF among adolescents (PR = 2·02, 95 % CI = 1·82, 2·25; PR = 1·88, 95 % CI = 1·68, 2·10), adults (PR = 1·86, 95 % CI = 1·75, 1·98; PR = 1·70, 95 % CI = 1·60, 1·80) and older adults (PR = 1·48, 95 % CI = 1·30, 1·69; PR = 1·24, 95 % CI = 1·09, 1·40). UPF consumption was negatively associated with diet quality across different age groups. Thus, interventions targeting UPF consumption should be implemented across life stages to improve overall diet quality.

We consider a finite-dimensional vector space $W\subset K^E$ over a field K and a set E. We show that the set $\mathcal {C}(W)\subset 2^E$ of minimal supports of W are the circuits of a matroid on E. When the cardinality of K is large (compared to that of E), then the family of supports of W is a matroid. Afterwards we apply these results to tropical differential algebraic geometry (tdag), studying the set of supports of spaces of formal power series solutions $\text {Sol}(\Sigma )$ of systems of linear differential equations (ldes) $\Sigma$ in variables $x_1,\ldots ,x_n$ having coefficients in . If $\Sigma $ is of differential type zero, then the set $\mathcal {C}(Sol(\Sigma ))\subset (2^{\mathbb {N}^{m}})^n$ of minimal supports defines a matroid on $E=[n]\times \mathbb {N}^{m}$, and if the cardinality of K is large enough, then the set of supports is also a matroid on E. By applying the fundamental theorem of tdag (fttdag), we give a necessary condition under which the set of solutions $Sol(U)$ of a system U of tropical ldes is a matroid. We give a counterexample to the fttdag for systems $\Sigma $ of ldes over countable fields for which is not a matroid.

In Greek literature, the barber is always portrayed as a garrulous chatterbox and his shop as a central place for gossip and rumours. Apart from these numerous anecdotes, however, few scholars have investigated the concrete realities of the profession and the actual status of barbers in the Greek East (including Egypt). This paper seeks to fill this gap. It is based on a careful social and economic analysis of the profession, including barbers’ workspaces, their social recognition as skilled craftsmen, their funerary and religious practices, their relationships with their clients, as well as their income, wages and expenses. It attempts to re-place ancient barbers in their socio-professional and socio-economic environment, and to reconstruct some aspects of their daily lives that go beyond the statements of ancient authors and their elite discourse. By systematically cross-referencing all available historical data (literary texts, inscriptions, papyri, ostraca, iconographic and archaeological sources), the paper shows how their lives and status differ from their representation in the literary sources in order to bring these everyday workers out of the shadows and rehabilitate them as historical actors in Greek and Hellenized societies.

In Colorado census tracts from 2021 to 2022, there was a 15% increase in the rate of candidemia for every 0.1 unit increase in social vulnerability index (SVI) (RR 1.15, 95% CI, 1.10, 1.20). Geographic social determinants of health included in SVI may be risk factors for candidemia.

Having a modern cooking stove at the household level provides an incomplete measure of cooking energy access. This limitation has necessitated the introduction of a multi-tier framework (MTF) to provide a more nuanced assessment. Thus, this study examines the overall, gendered, and rural-urban effects of cooking energy access under the MTF on health and time allocation to various household activities. Using the 2018 World Bank/ESMAP MTF dataset on Zambia, the study applies inverse probability regression adjustment with generalized propensity score to estimate pairwise average treatment effect on treated, by categorising households to tiers (0–5) based on six primary cooking energy attributes. The findings reveal that as households move up the MTF tiers, improvements in outcomes – such as reduced respiratory illness and better time allocation – are generally observed, though the magnitude of benefits tends to taper at higher tiers. Furthermore, women experience greater improvements relative to men, particularly in lower-tier transitions.

Parent attributions about their child significantly impact parenting behavior. The present study investigates parent attributions in the context of Parent–Child Interaction Therapy (PCIT) in child-welfare involved families. PCIT has two treatment phases, the first of which focuses on fostering a warm parent–child relationship and the second of which provides parents a positive discipline framework. This study characterizes individual differences in stability and change in parent attributions over the course of the intervention. It explores the impact of family treatment dosage on parent attributions as well as the impact of parent attributions on positive parenting skills outcomes. In a sample of 149 families involved with the child-welfare system (children aged 3–7, 59% nonwhite, 11% Hispanic, 50% female), multinomial logistic regression analyses and ANCOVAs were used. Results showed that engaging in additional treatment sessions increased the odds of parent attributions about their child increasing in warmth. Additionally, parents whose positive attributions of their child increased over time used more positive parenting behaviors in a cleanup task at posttreatment. These findings demonstrate that parent attributions about their child play an important role in behavioral parent training interventions. Future research should investigate how to leverage parent attributions to improve family treatment outcomes.

The study aimed to translate the Eating-Related Eco-Concern (EREC) questionnaire into Turkish, adapt it cross-culturally, and evaluate its psychometric properties. EREC is a ten-item scale measuring how adults consider ecological impact in food choices due to climate change concerns. The study was conducted in Mersin between November 2023 and February 2024 with 442 adults (18–65 years) through face-to-face interviews. The Turkish version was adapted using the Translation–Back Translation method, and language validity was ensured. Face validity was evaluated through a pilot study with forty participants. Construct validity was initially assessed using exploratory factor analysis (EFA) with data from 200 participants, followed by confirmatory factor analysis (CFA) conducted on an independent sample of 242 participants to verify the factor structure. The reliability of the scale was assessed by test-retest analysis with 106 participants from the main sample (n 442), and consistency was measured by the intraclass correlation coefficient (ICC). The factor structure and model fit were evaluated using indices such as Comparative Fit Index (CFI), Goodness-of-Fit Index (GFI) and root mean square error of approximation (RMSEA). 68·3 % of the participants were female, whereas 31·7 % were male. The group’s median BMI value was 24·3 (21·6–27·1), with 52·9 % classified as ‘normal’ according to the BMI classification. Factor 2 had a low score, but it was found to be adequate for other factors and the total scale score. The Turkish adaptation of the EREC questionnaire has been found to be a valid and reliable scale, as confirmed by comprehensive evaluations.

The article looks at instances of specialisation for specific linguistic contexts in ‘command’ and ‘inference’ uses of will and must. It tests the feasibility of different motivations for this specialisation, such as statistical and construal pre-emption. It also proposes a new motivation for specialisation, polysemous pre-emption, i.e. whether a strongly entrenched polyseme of a given expression might pre-empt the use of an expression with a less strongly entrenched polyseme. The investigation uses corpus analysis and distinctive collexeme analysis to test the three motivations (statistical, construal, and polysemous pre-emption). The results show that all instances of specialisation with will and must could be explained through construal pre-emption and/or polysemous pre-emption, thus making recourse to statistical pre-emption unnecessary.

The rise of U.S. inflation in 2021 and 2022 and its partial subsiding have sparked debates about the relative role of supply and demand factors. The initial surge surprised many macroeconomists despite the unprecedented jump in money growth in 2020–21. We find that the relationship between consumption and the theoretically based Divisia M3 measure of money (velocity) can be well modeled both in the short- and long-runs. We use the estimated long-run relationship to calculate the deviation of actual velocity from its long-run equilibrium and incorporate it into a P-Star framework. Our model of velocity significantly improves the performance of the P-Star model relative to using a one-sided HP filter to calculate trend velocity as used by other researchers. We also include a global supply pressures index in the model and find that recent movements in U.S. inflation largely owed to aggregate demand driven macroeconomic factors that are tracked by Divisia money with a smaller role played by supply factors.

Wastewater treatment is critically important and ceramic-membrane engineering is one of the most effective technologies for water filtration and purification. However, the materials used in the preparation of ceramic membranes are usually expensive, e.g. ZrO and Al2O3 membranes, reverse osmosis materials such as carbon-based thin-film nanocomposite TFNC ‘carbon nanotube, graphene-oxide’. Delicate, thin membranes employed for small-scale filtration usually require optimal supports for effective operation. The purpose of the present research, therefore, was to find a less expensive material for membrane supports while, at the same time, enhancing performance. Membrane supports were thus prepared from local clay materials and (25 wt.%) CaCO3 using an extrusion technique, which enabled the production of tubular supports. The CaCO3 is responsible for creating the pores in the samples during heat treatment due to the evolution of CO2 gas. Some characteristics of the supports were evaluated using X-ray diffraction, which identified quartz, gehlenite, sillimanite, H-bearing aluminous stishovite, and wollastonite. The support treated at 1000°C displayed significant mechanical properties (flexural strength, 11.58 MPa, measured using three-point bending tests) compared with supports treated at other temperatures. Moreover, the support sintered at 1000°C had an estimated permeability factor of 1052 L/h m2.bar after performing both time- and pressure-dependent flux measurements. Such properties make it possible to use these supports as multi-scale filtration membranes for purification and filtration applications after performing a standard filtration application on dirty water, resulting in a significant difference in terms of turbidity and waste content.
