“Geology in Everyday Life”: Designing Museum Educational Programmes (EP) with Students of Geology in the Science and Technology Museum (STM) of the University of Patras, Greece

This paper describes a study case of the Science and Technology Museum “Pedagogical Competence Programme” for students of the Department of Geology. It highlights an experimental approach of the museum for designing museum educational programmes with students. The museum succeeded from one side to develop a new program to offer to schools using participatory design and from the other to offer university students pedagogical experience through innovative, non-formal educational programmes, new ways to approach school students at all levels, cultivate their special skills, and enhance their knowledge, in order to familiarise them with the popularisation of science.

How expectancy violations facilitate learning to cope with pain – An experimental approach

Background: Expectations of painful sensations constitute a core feature of chronic pain. An important clinical question is whether such expectations are revised when disconfirming experiences are made (e.g., less pain than expected). The present study examined how people adjust their pain expectations when the experience of decreasing pain is expected vs. unexpected. Methods: In a novel experimental paradigm, people who frequently experience pain (N=73) were provided with painful thermal stimulations. Unbeknownst to participants, the temperature applied was decreased from trial to trial. Based on the experimental instructions provided, this experience of decreasing pain was expected in one condition (expectation-confirmation), whereas it was unexpected in another (expectation-disconfirmation). Results: Expectation violations were higher in the expectation-disconfirmation condition than in the expectation-confirmation condition, F(1, 69) = 6.339, p = .014, ηp² = .084. Participants from the expectation-confirmation condition showed a greater adjustment of their pain expectations than the expectation-disconfirmation condition, F(1.666, 114.929) = 7.486, p = .002, ηp² = .098. Across groups, expectation adjustment was related to increases in pain tolerance (r = .342, p = .004) and the ability to cope with pain (r = .234, p = .045) at a one-week follow-up. Conclusions: Participants were more likely to adjust their pain expectations when the experience of decreasing pain was expected. Though participants who experienced large discrepancies between expected and experienced pain were hesitant to adjust their pain expectations immediately, experiencing expectation violations increased their ability to cope with pain one week later, suggesting some beneficial longer-term effects of expectation violations.

Experimental Approach of Quadriceps Strength Measurement: Implications for Assessments in Critically Ill Survivors

(1) Background: The supine testing position is suitable for early quadriceps strength (QS) assessment in intensive care unit, while a seated position is more appropriate for survivors who have regained mobility. Acquiring consistent measurements is essential for longitudinal follow-up. We compared the QS generated in different settings in healthy volunteers. (2) Methods: Isometric QS was assessed using a MicroFet2 and standardised protocols comparing different modalities. Hip and knee flexion angles were, respectively, 45° and 40° (H45-K40) in the supine position, and both at 90° (H90-K90) in the seated position. Dynamometer was either handheld (non-fixed configuration, NFC), or fixed (FC) in a cubicle. (3) Results: QS in H90–K90 and H45-K40 positions were strongly correlated, but QS was higher in the later position regardless of the configuration. Compared to H45-K40, biases of 108.2N (or 28.05%) and 110.3N (27.13%) were observed in H90-K90 position, respectively, in the NFC and FC. These biases were independently and positively associated with QS (p < 0.001). For both position, there were no significant differences between QS measured in NFC or FC. (4) Conclusions: The quadriceps was less efficient in the seated position, compared to the supine position, in healthy volunteers. These findings have practical implications for further assessments and research in critically ill patients.

The effect of personal relative deprivation on food choice: An experimental approach

Growing evidence suggests that relative disadvantage is more relevant than absolute socioeconomic factors in explaining disparities in healthfulness of diet. In a series of pre-registered experiments, we tested whether personal relative deprivation (PRD), i.e. the sense that one is unfairly deprived of a deserved outcome relative to others, results in choosing more palatable, rewarding foods. Study 1 (N = 102) demonstrated the feasibility and effectiveness of a game for inducing real-time experiences of PRD. Study 2 (N = 287) showed no main effect of PRD condition on hypothetical food choices, but an interaction between chronic PRD and condition revealed that those in the PRD condition chose more rewarding foods when feeling chronically deprived. In Study 3 (N = 260) the hypothesized main effect was found on real, non-hypothetical food choices: those in the PRD condition chose more rewarding foods, controlling for sensitivity to palatable food. Our results provide preliminary indications that the experience of being relatively deprived, rather than the objective amount or resources, may result in a higher preference for high-caloric and palatable foods. It may be suggested that efforts to reduce societal disparities in healthfulness of diet may need to focus on perceptions of injustice beyond objective inequalities.

How Efficient are the Romanian Sports Federations? A Theoretical and Experimental Approach

Examining the links between performance and financial issues has been, and still is, subject of a great number of researches both in the business and in the non-profit environment. In this respect, the world of sports has not been bypassed either, using concepts and / or instruments from accounting, economics or statistic areas in order to analyse a firm or an NGO in the sport industry and his success. The present study represents one of the first attempt to value the Romanian sports federations’ activity which is not based solely on the scores attained following places and medals won by athletes participating in the national and international competition system. And it is intended to identify an appropriate methodology to highlight how efficient the sports federations have been in 2019 year, reporting the results obtained to the resources used, from a domestic perspective (meaning the participation in national sports events and the scores obtained). This paper addresses 12 Romanian sports federations (out of 75 federations on sport branches) and their efficiency, through the lens of several input, output and outcome indicators, using public data gathered from various sources - the Romanian Ministry of Finance, the National Institute of Statistics, the Romanian Ministry of Youth and Sports. Using statistical tools, such as Spearman rank correlation, as well as statistical methods, such as standardization, we developed an efficiency calculation methodology, which could be used to support managerial team to improve and / or reshape federations' activities, if necessary.

Economic analysis of the environmental sustainability of agriculture: recent studies using quasi-experimental methods

PurposeThe purpose of this review article is to demonstrate how the quasi-experimental approach has been used to study environmental and natural resource issues related to agricultural production.Design/methodology/approachThis review article first provides a short introduction to the quasi-experimental approach using the potential outcomes framework and then uses studies on the environmental sustainability of agricultural production to illustrate how quasi-experimental methods have been applied. Papers reviewed consist of studies that estimate the environmental externalities from agricultural production, evaluate agri-environmental and other related policies and programs, and demonstrate issues related to on-farm resource use and climate adaptation.FindingsDifference-in-differences (DID) and two-way fixed effects methods that utilize the spatial and temporal variation in panel data are widely used to estimate the causal impact of changes in agricultural production and policy on the environment. Utilizing the discontinuities and limits created by agricultural policies and regulations, local treatment effects on land and other input use are estimated using regression discontinuity (RD) or instrumental variable (IV) methods with cross-sectional data.Originality/valueChallenges faced by the food systems have made agricultural sustainability more critical than ever. Over the past three decades, the quasi-experimental approach has become the powerhouse of applied economic research. This review article focuses on quasi-experimental studies on the environmental sustainability of agriculture to provide methodological insights and to highlight gaps in the economics literature of agricultural sustainability.
