Could a Behavioral Model Explain Adherence to Second-Level Colonoscopy for Colon Cancer Screening? Results of a Cross-Sectional Study of the Palermo …
2022
According to Italian Essential Levels of Assistance (ELA), a colonoscopy is strongly recommended after a positive fecal occult blood test (FOBT) due to its effectiveness in early colorectal cancer detection. Despite the evidence, the Palermo province population (Italy), after a positive FOBT, have a lower colonoscopy adherence compared to Italian standards. This cross-sectional study analyzed patients’ perceptions of colonoscopy procedures to understand the reasons for non-adherence. Patients with a positive FOBT who did not undergo a colonoscopy within the national organized screening program were administered a telephone interview based on the Health Belief Model (HBM) questionnaire. The …

Dynamics of soil organic matter pools after agricultural abandonment
2014
Changes of land use from croplands to natural vegetation usually increase Carbon (C) stocks in soil. However, the contribution of old and new C to various pools still is not clearly analyzed.We measured the 13C signature of soil organic carbon (SOC) pools after vegetation change from vineyard (C3) to grassland (C4) under Mediterranean climate to assess the changes of old and new C in total SOC, microbial biomass (MB), dissolved organic C (DOC), and CO2 efflux from soil. Development of the perennial grass Hyparrhenia hirta (C4) on vineyard abandoned for 15 or 35 years ago increased C stocks for 13% and 16%, respectively (in the upper 15 cm). This increase was linked to the incorporation of n…
Revisiting the cross‐sectional and prospective association of physical activity with body composition and physical fitness in preschoolers: A composi…
2022
Background Information is limited for the benefits of physical activity (PA) in preschoolers. Previous research using accelerometer-assessed PA may be affected for multicollinearity issues. Objectives This study investigated the cross-sectional and prospective associations of sedentary behaviour (SB) and PA with body composition and physical fitness using compositional data analysis. Methods Baseline PA and SB were collected in 4-year-old (n = 315) using wrist-worn GT3X+ during seven 24 h-periods. Body composition (air-displacement plethysmography) and physical fitness (PREFIT test battery) were assessed at baseline and at the 12-month follow-up. Results Increasing vigorous PA at expenses o…
Influence of a Thiolate Chemical Layer on GaAs (100) Biofunctionalization: An Original Approach Coupling Atomic Force Microscopy and Mass Spectrometr…
2013
International audience; Widely used in microelectronics and optoelectronics; Gallium Arsenide (GaAs) is a III-V crystal with several interesting properties for microsystem and biosensor applications. Among these; its piezoelectric properties and the ability to directly biofunctionalize the bare surface, offer an opportunity to combine a highly sensitive transducer with a specific bio-interface; which are the two essential parts of a biosensor. To optimize the biorecognition part; it is necessary to control protein coverage and the binding affinity of the protein layer on the GaAs surface. In this paper; we investigate the potential of a specific chemical interface composed of thiolate molec…
Diseño de un sistema de apoyo a la regulación social del aprendizaje en los xMOOC
2019
Esta investigación tiene como objetivo estudiar los procesos de regulación del aprendizaje, atendiendo tanto a su dimensión individual como social, en entornos de xMOOC. En concreto, se propone analizar cómo los procesos de autorregulación, corregulación y regulación social compartida pueden apoyarse y promoverse en este tipo de contextos abiertos y masivos para conseguir un aprendizaje más profundo. Para ello, se aplica un modelo de investigación basada en el diseño que permite intervenir directamente en la práctica pedagógica, a través de un proceso cíclico de cuatro etapas: diseño, intervención, evaluación y reflexión y rediseño de un sistema de apoyo a la regulación del aprendizaje en u…

Pubblicato nel quinto fascicolo di Versus. Quaderni di studi semiotici, il lungo, articolato, complesso saggio di Paolo Fabbri che qui riproponiamo appariva in un momento topico per l’investigazione sui segni, i linguaggi, il senso, la significazione . Era il 1973, periodo euforico per le scienze umane, contrassegnato da grandi folgorazioni metodologiche e correlative esplorazioni di campo, dall’esibizione di consistenti nuove idee e dall’ambiziosa edificazione di un certo numero di modelli previsionali per la spiegazione della realtà sociale, antropologica e culturale. L’idealismo storicista sembrava scomparso, e molto marxismo sedicente rigoroso con lui, soppiantati dal trionfo non parall…
Post-it
2020
The history of the invention of post-it, the famous small piece of yellow paper with a re-adherable strip of glue, help us see how designing can be a way of redesigning more than a creation ex nihilo. A designer is who works on the meaning of things, focusing on the relations an artifact creates with humans and non humans. Standing in front of an object, then, the question changes: not what is design but when.
Looking ahead in games research
2021
This thematic issue presents a number of emerging scholarships into the study of digital gaming. The articles are based on a 2019 symposium on game studies hosted by the Digital Games Research section of ECREA. As the phenomena related to digital gaming keep on evolving and emerging, so must research keep up with the times and constantly challenge itself. Whether speaking about validating previously developed research methods, imagining totally new ones, or even challenging the whole philosophy of science on which research is being done, there is a constant need for reappraisal and introspection within games research. As a cultural medium that has become deeply embedded into the social fabr…
