Survival Prediction in Intrahepatic Cholangiocarcinoma: A Proof of Concept Study Using Artificial Intelligence for Risk Assessment
2021
Several scoring systems have been devised to objectively predict survival for patients with intrahepatic cholangiocellular carcinoma (ICC) and support treatment stratification, but they have failed external validation. The aim of the present study was to improve prognostication using an artificial intelligence-based approach. We retrospectively identified 417 patients with ICC who were referred to our tertiary care center between 1997 and 2018. Of these, 293 met the inclusion criteria. Established risk factors served as input nodes for an artificial neural network (ANN). We compared the performance of the trained model to the most widely used conventional scoring system, the Fudan score. Pr…
How to find information on national food and nutrient consumption surveys across Europe: systematic literature review and questionnaires to selected …
2009
The present research was conducted within the framework of the EURopean micronutrient RECommendations Aligned project. In order to identify the best practice in assessing nutrient intakes, a search strategy for collecting data from national food consumption surveys/studies in Europe was developed. Systematic literature searches were carried out on twenty-eight European and the four European Free Trade Association countries. A questionnaire was also sent to two to five experts in each country. Systematic reviews using PubMed yielded 12 703 abstracts that were reduced to 200 studies using inclusion and exclusion criteria. Similarly, a search of ministry web sites yielded 3033 hits, and subseq…
First Life Cycle Impact Considerations of Two Wave Energy Converters
2018
The work presents two different revolutionary devices for the utilization of a new entry of renewable energy sources: sea wave. The first technology is based on linear generators, able to directly converts a linear motion into electrical output, limiting to minimum the chain of energy conversion. The other solution is based on a mechanical motion converter, coupled with alternators. The scope of this paper is to compare the two different systems designed by University of Palermo, through Life Cycle Assessment, in order to evaluate the global effects of the two systems to the environment.
¿Qué sabe el alumnado de secundaria sobre la Unión Europea? Implicaciones para el aprendizaje
2017
El desarrollo de la Dimensión Europea en la Educación es un objetivo vinculado a la construcción de la identidad europea y al ejercicio de una ciudadanía activa crítica y responsable. El artículo analiza el conocimiento de los estudiantes de Educación Secundaria Obligatoria sobre la Unión Europea. En el estudio participaron 705 alumnos de cinco centros de educación secundaria obligatoria de cuatro comunidades autónomas españolas. Se diseñó una prueba de veinticuatro ítems sobre: a) las instituciones europeas, b) la historia de la cooperación europea, c) la ciudadanía Europea, d) Europa en la vida cotidiana, e) la identidad social y cultural, y f) derechos humanos y responsabilidades. Los re…
The development of secondary students’ feedback literacy: Peer assessment as an intervention
2020
A growing body of research has recognized the importance of students’ having active roles in feedback processes. Feedback literacy refers to students’ understandings of and participation in feedback processes, and research on students’ feedback literacy has so far focused on higher education; secondary schools have not received attention. This case study investigates secondary students’ feedback literacy and its development in the context of formative peer assessment. From various data sources, three categories of students’ feedback literacy were identified, and criteria for the levels of literacy in each category were created. The criteria were used in the coding of seventh- and eighth-gra…
Factors behind low reading literacy achievement
2004
The initial results of the Programme for International Student Assessment (PISA) indicated that Finnish and Swedish students are among the best readers in all OECD countries. However, the literac ...
Disposição ao pensamento crítico, nível acadêmico, gênero e resolução de problemas no ensino médio
2021
Resumen El propósito de este estudio fue investigar la posible influencia de la disposición hacia el pensamiento crítico, el nivel académico y el género (variables independientes) sobre el desempeño en resolución de problemas de estudiantes de secundaria (variable dependiente). Han participado 114 estudiantes de educación secundaria españoles, 55 chicos y 59 chicas, de 3º y 4º de ESO y de 1º de Bachillerato (9º, 10º y 11º grado, respectivamente). A todos ellos se les ha administrado un cuestionario sobre disposición hacia el pensamiento crítico y una prueba de resolución de problemas (un problema de las pruebas PISA). De la matriz de correlaciones producto-momento de Pearson entre variables…
The Role of Physical Education Homework to Adolescent Girls’ Physical Activity in Finland
2019
Introduction: There is an urgent need for active strategies to promote physical activity (PA) among female adolescents, as they are at greater risk of physical inactivity. In addition to Physical Education (PE) in school, to reach adequate levels of PA, young people need to participate in PA during the school day and/or after-school hours and/or in the before-school period. One week of objectively measured and self-reported information enlightens the status quo of adolescent girls’ PA and the role that PE homework plays. Purpose: The purpose of this study was to examine girls’ objectively measured PA in a lower secondary school as part of the Physical Education Homework Study, a project con…
Seismic assessment and retrofit of a concrete building highly damaged by reinforcement corrosion
2020
In existing concrete structures damaged by corrosion, the limited quantity and poor distribution of reinforcements as well as a lack of seismic details are common to many cases because they are built before the advent of seismic codes. In this paper the seismic assessment and retrofit of a concrete building sited in Sicily is presented in order to show a case-study of a corroded reinforced concrete structure to be trans-formed with new structural elements for functional reasons linked to Civil Protection. After many decades of complete abandonment, the structure was strengthened with different strategies, allied to the construction of new steel-concrete composite floors: concrete and steel …
Informal employment in developing countries
2012
There is an ongoing debate among researchers and policy makers, whether informal sector employment is a result of competitive market forces or labor market segmentation. More recently it has been argued that none of the two theories sufficiently explains informal employment, but that the informal sector shows a heterogenous structure. For some workers the informal sector is an attractive employment opportunity, whereas for others – rationed out of the formal sector – the informal sector is a strategy of last resort. To test the empirical relevance of this hypothesis we formulate an econometric model which allows for several unobserved segments within the informal sector and apply it to the …
