Gene expression centroids that link with low intrinsic aerobic exercise capacity and complex disease risk
2010
A strong link exists between low aerobic exercise capacity and complex metabolic diseases. To probe this linkage, we utilized rat models of low and high intrinsic aerobic endurance running capacity that differ also in the risk for metabolic syndrome. We investigated in skeletal muscle gene-phenotype relationships that connect aerobic endurance capacity with metabolic disease risk factors. The study compared 12 high capacity runners (HCRs) and 12 low capacity runners (LCRs) from generation 18 of selection that differed by 615% for maximal treadmill endurance running capacity. On average, LCRs were heavier and had increased blood glucose, insulin, and triglycerides compared with HCRs. HCRs we…
Divergent temperature-specific metabolic and feeding rates of native and invasive crayfish
2022
Temperature is one of the most important factors governing the activity of ectothermic species, and it plays an important but less studied role in the manifestation of invasive species impacts. In this study, we investigated temperature-specific feeding and metabolic rates of invasive and native crayfish, and evaluated how temperature regulates their ecological impacts at present and in future according to different climatic scenarios by bioenergetics modelling. We conducted a series of maximum food consumption experiments and measured the metabolic rates of cold-adapted native noble crayfish (Astacus astacus) and invasive signal crayfish (Pacifastacus leniusculus) originally from a warmer …
Towards a reduction of greenhouse gas emission from wastewater treatment plants: a new plant wide experimental and modelling approach
2016
The increasing interest in greenhouse gas (GHG) emissions from wastewater treatment plants (WWTPs) has led to the development of new tools for their design and management. Studies about gas emissions show that the sewer collection and the wastewater treatment plant are anthropogenic GHG potential sources, so they contribute to the climate change and air pollution. A wastewater treatment plant receives wastewater from sewers and, while produces treated water for discharge into surface water, emits the three major greenhouse gases, CO2, CH4, and N2O, during the treatment processes, and additional amounts of CO2 and CH4 from the energy demands (Bani Shahabadi et al., 2009). Indeed, energy cons…
Effect of Sitting Posture on Sit-Skiing Economy in Non-disabled Athletes
2020
This study focused on resolving the differences in economy between two common sit-skiing postures used by disabled athletes, suspected to be the most and least effective. Ten experienced non-disabled male cross-country skiers went through an incremental testing protocol with an ergometer simulating double poling in two sitting postures “kneeing” and “knee-high.” The protocol consisted of 3 × 4 min steady-state stages (13, 22, and 34% of maximal sprint power output). Subjects' respiratory gases and heart rate were measured and blood lactate concentrations were determined. In addition, pulling forces and motion capture recordings were collected. Oxygen consumption was 15.5% (p < 0.01) higher …
“Natural wages dynamics in a Ricardian growth model”
2006
Ricardian growth models are generally built on the assumption of a constant natural wage. Such an assumption conceals the fact that classical economists were aware that in growing economies workers' normal pattern of consumption steadily rise both in terms of quantity and quality. In the first part of the chapter we gather some classical hints on the relationship between economic growth and natural wages in order to provide a rational reconstruction of the classical point of view on natural wage dynamics. In the second part of the chapter we propose a formal analysis of the dynamics of a Ricardian model with endogenous natural wage
Differentiation of Self-Assessment and objective Inequalities in the Level of Consumption of Rural Households
2017
Niniejszy artykuł jest poświęcony problematyce samooceny nierówności poziomu konsumpcji na wsi w Polsce jako podstawowej determinanty poziomu życia. Celem zaprezentowanych w nim badań była próba identyfikacji zróżnicowania subiektywnych ocen poziomu życia gospodarstw domowych na wsi oraz porównania ich z wybranymi obiektywnymi charakterystykami sytuacji materialnej tych podmiotów. Jako najbardziej reprezentatywny wskaźnik sytuacji materialnej gospodarstwa domowego przyjęto poziom wydatków konsumpcyjnych. Przeprowadzono analizę porównawczą relacji między samooceną a wydatkami konsumpcyjnymi i wybranymi charakterystykami gospodarstw zaliczanych do poszczególnych grup społeczno- -ekonomicznych…
The association of cannabis use with fast-food consumption, overweight, and obesity among adolescents aged 12-15 years from 28 countries
2022
Background: Cannabis legalization and use have risen globally. However, the association between cannabis use, eating behaviors and body weight among adolescents is yet unexplored. Objectives: This study examined the association between cannabis use, fast-food consumption, overweight and obesity in 28 countries using data from the 2010–2016 Global School-Based Student Health Survey. Methods: Multivariable logistic regression and meta-analysis were performed among a sample of 83,726 adolescents (48.7% females) aged 12–15 years, mean (SD) age of 13.8 (0.9) years. Results: The overall prevalence of cannabis use (in past 30 days) and fast-food consumption (in past 7 days) were 2.8% and 57.3% res…
Organic food consumption: The relevance of the health attribute
2020
During the last decades, organic food products have become the main sustainable alternative to conventional food consumption. Among the several organic food attributes that consumers recognize in organic food, healthiness has been reported as the primary motivation to buy products certified as organic. The objective of the current study is to assess the relative weight of the health attribute among other recognized organic food attributes. To achieve this aim, a multiple price list (MPL) methodology is adopted to elicit consumers&rsquo
Sustainable Food Consumption Practices: Insights into Consumers’ Experiences
2021
In recent years, the increasing consumer concern towards food safety, environmental sustainability and social justice issues have stimulated new consumption practices more oriented towards social, economic, and environmental sustainability [1–3]. This includes the growing consumers’ preference for organic food, local food, and other sustainable food and beverage consumption (Contribution 1) [ 4], as well as the spread of alternative distribution chains, which emphasise the importance of local food productions [ 5 ], the short-distance transportation of food, and the direct relationship between consumers and producers, although, as Kwil and colleagues (Contribution 2) highlighted in this Spe…
What is meaningful for responsible shoppers in online fashion retail?
2022
This qualitative study investigates what is meaningful for responsible shoppers in online fashion retail. The study aims to identify and describe these essential themes from the customers’ perspective. The data were collected by interviewing nine self-proclaimed responsible shoppers aged 26–51 years. All participants were female. The findings highlight six meaningful themes for responsible shoppers. These include 1) comprehensive and versatile information; 2) familiar brands and retailers; 3) domesticity; 4) pricing; 5) justification of purchase; and 6) the durability of fashion wear. The study indicates that these meaningful themes are related to the online store characteristics and brands…
