Seasonal cues to food scarcity and calorie cravings: Winter cues elicit preferences for energy-dense foods

2021

Abstract Winter cues signal a scarcity of food. Birds and mammals respond to such environmental cues by consuming more energy. They convert this surplus into body fat that serves as a buffer against impending food shortages. Similarly, humans exhibit higher obesity rates among food-insecure populations. However, to date, it has been unclear whether winter cues qualitatively affect consumers’ food preferences. Results from five studies ( N = 865), with one of them preregistered, show that watching videos depicting winter cues elicits thoughts about energy-dense foods and survival. Such cues elicit higher preferences for energy-dense than low-calorie foods, as verified by meta-analytic eviden…

Burnout and work engagement: Independent factors or opposite poles?

2006

Burnout researchers have proposed that the conceptual opposites of emotional exhaustion and cynicism (the core dimensions of burnout) are vigor and dedication (the core dimensions of engagement), respectively (Maslach & Leiter, 1997; Schaufeli, Salanova, González-Romá, & Bakker, 2002). We tested this proposition by ascertaining whether two sets of items, exhaustion-vigor and cynicism-dedication, were scalable on two distinct underlying bipolar dimensions (i.e., energy and identification, respectively). The results obtained by means of the non-parametric Mokken scaling method in three different samples (Ns = 477, 507, and 381) supported our proposal: the core burnout and engagement d…

Protection of the European Energy Consumers’ Rights within the Globalization Context

2015

Abstract The ambivalence of globalization determines the consumer to comply with the legislation of the nation state as well as the UE legislation through the norms of the European Parliament regarding the rights of the European consumer, the labelling in the energetic field and the European Book of the consumer of energy. The consumers have the essential information that are to allow the attaining of objectives referring to the hedging of vulnerable citizens, less red tape, changing of the supplier, more information but also consumers’ hedging against the selling practices of non-loyal selling practices. The main objectives of the article aim at outlining the main theoretical methodologica…

Societal implications of sustainable energy action plans: from energy modelling to stakeholder learning

2019

This article investigates the potential impact of sustainable energy action plans (SEAPs) on local development through a two-step methodology involving participatory planning and quantitative analysis. The first phase relies on a participatory system mapping (PSM) approach and generates a causal structure at the basis of the urban model. In the second phase, we transform the qualitative map into a system dynamic model which evaluates the effect of the SEAP on social, economic and environmental indicators. This methodology was applied to the case of Cascina Municipality (Italy). Through scenario analysis, we show that some indirect feedback can harm the achievement of the 20% emission reduct…

Patologie asbesto-correlate osservate a Palermo e Provincia tra lavoratori esposti ad amianto [Asbestos-related diseases observed in Palermo (Italy) …

2011

È stato realizzato uno studio su lavoratori professionalmente esposti ad amianto con l'obiettivo di esaminare i casi di patologia asbesto-correlata nella Provincia di Palermo tra il 2005 e il 2009. I dati sono stati raccolti dalle cartelle cliniche e dai verbali delle deleghe di indagine da parte delle Procure di Palermo e di Termini Imerese al Servizio di Prevenzione e Sicurezza negli Ambienti di Lavoro dell'Azienda Sanitaria Provinciale (ASP 6) di Palermo. La regressione logistica multinomiale evidenzia una associazione significativa tra fumo di tabacco e carcinoma polmonare e tra coloro che hanno cominciato a lavorare precocemente e la presenza di asbestosi e placche pleuriche. La casist…

El sentido deportivo de la vida en la hermenéutica raciovitalista de Ortega y Gasset

2020

El trabajo pretende mostrar, en primer lugar, que el raciovitalismo de José Ortega y Gasset constituye una de las líneas posibles del proceso de transformación hermenéutica del pensamiento contemporáneo. La impronta nietzscheana de carácter hermenéutico en el desarrollo del pensamiento orteguiano se manifiesta en aspectos muy relevantes, como la importancia del cuerpo y la innovadora noción de vida, que son asuntos decisivos para comprender el deporte.En segundo lugar, hay que aprovechar las ricas reflexiones de Ortega y Gasset sobre el deporte, que tienen un alcance muy relevante para la entera vida humana, a partir de la reivindicación de una noción de cuerpo viviente (Leib) y de una nuev…

Assessment of toxicity hazards of dredged lake sediment contaminated by creosote.

2000

In order to predict the potential toxicity hazards of sediment remediation by dredging, an experimental laboratory simulation was made by investigating seven ratios of creosote-contaminated sediment (Lake Jamsanvesi, central Finland) and artificial lake water mixtures. Sediment was suspended in water at the ratios of 1:1, 1:2, 1:4, 1:8, 1:16, 1:32, 1:64, 1:128 v/v. The elutriates were analysed for the acute toxicity by photoluminescence bacterial and waterflea (Daphnia magna Straus) tests. The concentrations of polycyclic aromatic hydrocarbons (PAHs) are determined by gas chromatography (GC/FID). The elutriate of ratio 1:2 was most toxic to bacteria (EC50 = 4.5%), whereas the ratio 1:4 was …

An Early Beginning of Citizen Science: Adolescents Experiencing Urban Energy Usages and Air Pollution

2021

Here, we report on the process and development of high school science projects, which were inspired by a citizen science program focused on urban monitoring. We gathered and discussed two 1980s projects’ data, involving 2600 students, 80 teachers, 15 scientists and 20 stakeholders. We added recent survey data from speaking with the former participants. Our analysis revealed key findings: (1) the process of a student-driven science investigation engages students in the scientific practices; (2) it is important to bring together scientists, teachers and students, reflecting the importance of multi-dimensional learning; and (3) citizen science was born before the 1990s, when the term came into…
