An eco-label for the airline industry?

2017

Air travel plays a vital role in today's life because it makes remote destinations accessible and short getaways possible. Despite its benefits, air transportation contributes heavily to climate change. Behavioral change is seen as a key driver in mitigating the environmental impacts of air travel. One way to encourage behavioral change is to use eco-labels. This study explores how an eco-label could be developed for the airline industry to function as a potential driver for behavioral change. 12 interviews with airline industry experts were conducted and thematically analyzed. Empirical results were then combined with prior research and the following five criteria essential for the develop…

The effect of an eco-label on the booking decisions of air passengers

2022

In the last few years there has been an increasing attempt to find solutions on how to mitigate the environmental impacts of air travel. Behavioral change has hereby been identified as the measure with the most significant impact. One way to encourage behavioral change is the use of eco-labels. Eco-labels have, to date, received scant attention in the aviation industry, and their effect on air travel behavior is still largely unknown. This study explores the effect of an eco-label on the booking decisions of passengers. We conduct a stated choice experiment with 553 air passengers. Our findings show that providing passengers with an eco-label leads to behavioral change, as the label makes t…

Anchoring Belonging Through Material Practices in Participatory Arts-Based Research

2020

How do people understand belonging and what kinds of stances toward belonging do they take? What kind of knowledge or ways of knowing (EISNER, 2008) does artistic practice yield about belonging? We ask these questions in this article, which is based on the research project Crossing Borders, in which we used participatory arts-based methods to study belonging. We invited participants to explore the notion of belonging in three parallel workshops drawing on different art forms, film, writing and visual arts. The goal of the workshops was for each participant to produce an artwork that deals with belonging. In the article, we identify four stances that the participants expressed toward the con…

Patrones y estrategias en la colaboración científica: la percepción de los investigadores

2018

La colaboración constituye una práctica generalizada en las actividades de investigación, cuyas características e implicaciones se han analizado generalmente a partir de las coautorías de las publicaciones científicas. Con el objeto de profundizar en el conocimiento de este fenómeno, se ha administrado un cuestionario a una muestra de 3070 investigadores de las universidades de la Comunidad Valenciana (España), analizando por ramas de conocimiento (Artes y Humanidades, Ciencias, Ciencias de la Salud, Ciencias Sociales y Jurídicas e Ingeniería y Arquitectura), categorías académicas y sexo, cómo se establecen los contactos entre los investigadores (pre-colaboración), el desarrollo de la colab…

A Comparative Analysis of the Social Performance of Global and Local Berry Supply Chains

2016

The goal of this paper is twofold: to comparatively analyze the social performance of global and local berry supply chains and to explore the ways in which the social dimension is embedded in the overall performance of food supply chains. To achieve this goal, the social performance of five global and local food supply chains in two countries are analyzed: wild blueberry supply chains in Latvia and cultivated raspberry supply chains in Serbia. The study addresses two research questions: (1) What is the social performance of the local and global supply chains? (2) How can references to context help improve understanding of the social dimension and social performance of food supply chains? To…

Dietary polyphenols as antidiabetic agents: Advances and opportunities

2020

Abstract Dietary polyphenols have been widely investigated as antidiabetic agents in cell, animals, human study, and clinical trial. The number of publication (Indexed by Web of Science) on “polyphenols and diabetes” significantly increased since 2010. This review highlights the advances and opportunities of dietary polyphenols as antidiabetic agents. Dietary polyphenols prevent and manage Type 2 diabetes mellitus via the insulin‐dependent approaches, for instance, protection of pancreatic islet β‐cell, reduction of β‐cell apoptosis, promotion of β‐cell proliferation, attenuation of oxidative stress, activation of insulin signaling, and stimulation of pancreas to secrete insulin, as well as…

Do Tengmalm's owls see vole scent marks visible in ultraviolet light?

1997

Scent markings (urine and faeces) of small mammals are visible in ultraviolet (UV) light. Diurnal kestrels, Falco tinnunculususe them as a cue to find areas of food abundance. We studied whether vole-eating, nocturnal Tengmalm's owls, Aegolius funereuscan see vole scent marks using UV-vision. In a laboratory experiment, 14 young (less than 6 months old) and 14 adult (more than 6 months old) owls were individually given a choice between four adjacent arenas: (1) an arena with vole urine and faeces in UV light; (2) an arena with vole urine and faeces in visible light; (3) a clean arena in UV light; and (4) a clean arena in visible light. Owls did not prefer any of the four arenas. Our results…

Ferritin synthesis by Caco-2 cells as an indicator of iron bioavailability: Application to milk-based infant formulas

2007

The bioavailability of iron from milk-based infant formulas was estimated by an in vitro system including enzymatic digestion, iron uptake by Caco-2 cells and ferritin determination via an enzymoimmunoassay (ELISA). Positive correlations (p < 0.01) were found between the Fe(II) added to Caco-2 cells and ferritin synthesis and between the amount of dialyzed iron added to the cell culture and ferritin synthesis. The comparison of the bioavailability of iron from different milk-based formulas showed that adapted formulas having the same composition but differing in the iron salts added yielded similar ferritin levels. The same happened with follow-up formulas differing only in the presence or …

Iron and zinc bioavailability in Caco-2 cells: Influence of caseinophosphopeptides

2013

Abstract A study has been made of the influence of two pools of caseinophosphopeptides (CPPs) obtained from α s - and β-casein (CN) fractions, and of three specific CPPs (β-CN(1–25)4P, α s1 -CN(64–74)4P and α s2 -CN(1–19)4P), on iron bioavailability (ferritin synthesis) and zinc bioavailability (retention, transport and uptake of zinc) in Caco-2 cells. α-CPP and β-CPP pools did not improve ferritin synthesis, but the three specific CPPs showed an increase in ferritin synthesis in Caco-2 cells versus iron sulphate, β-CN(1–25)4P being the most effective. In relation to zinc bioavailability, α-CPPs, β-CPPs, α s1 -CN(64–74)4P and β-CN(1–25)4P increased zinc uptake. However, this increase was of…
