Social Work in the Area o Social Support for the Family with a Disabled Child
2013
In the times of continually changing socioeconamic conditions behind the functioning o f contemporary families, many of them have to cope with a variety of problems of everyday life. Families raising disabled children come to face a particularly hard situation in this respect, since problems pertaining to the emotional sphere, ones related to providing care and education, securing material and daily life needs, as well as those of the social nature, which appear within the families, are additionally augmented by the fact of their child’s disability. Solving the problems is often impossible relying on the limited resources of the family members themselves. And the support extended to them by…
A Curvature Based Method for Blind Mesh Visual Quality Assessment Using a General Regression Neural Network
2016
International audience; No-reference quality assessment is a challenging issue due to the non-existence of any information related to the reference and the unknown distortion type. The main goal is to design a computational method to objectively predict the human perceived quality of a distorted mesh and deal with the practical situation when the reference is not available. In this work, we design a no reference method that relies on the general regression neural network (GRNN). Our network is trained using the mean curvature which is an important perceptual feature representing the visual aspect of a 3D mesh. Relatively to the human subjective scores, the trained network successfully asses…
La fides e la promessa: forme di reciprocità tra dèi e uomini nella riscrittura di Ovidio
2017
Nelle rielaborazioni ovidiane dei racconti mitici greci, emergono diversi casi in cui la relazione tra esseri umani e divinità è riscritta alla luce della nozione romana di fides. Ma se la quasi totalità di questi miti, in cui il dio promette all’interagente mortale un pegno, un dono o un privilegio, è giustificata dalla presenza di vincoli di tipo amoroso, parentale o devozionale, un caso a parte rappresenta il racconto di Numa Pompilio e Giove (Fast. 3. 285-392) – un racconto Romano – in cui l’agente umano merita i pignora certa del dio e instaura con lui un rapporto di reciprocità. Il contributo si propone di esaminare questa rappresentazione della fides pollicita attraverso un confronto…
Empirical Study on the Relationship between the Cross-Correlation among Stocks and the Stocks' Volatility Clustering
2013
In this paper we discuss univariate and multivariate statistical properties of volatility with the aim of understanding how these two aspects are interrelated. Specifically, we focus on the relationship between the cross-correlation among stock's volatilities and the volatility clustering. Volatility clustering is related to the memory property of the volatility time-series and therefore to its predictability. Our results show that there exists a relationship between the level of predictability of any volatility time-series and the amount of its inter-dependence with other assets. In all considered cases, the more the asset is linked to other assets, the more its volatility keeps memory of …
A review of methods to assess connectivity and dispersal between fish populations in the Mediterranean Sea
2013
Fish populations are linked to each other via dispersal of individuals as eggs, larvae, juveniles or adults. The understanding of this process, known as connectivity, has a pivotal role for the management of overexploited fish stocks and the development of accurate conservation strategies. Knowledge on connectivity and fish movements is considered fundamental toward the correct design of marine protected area (MPA) networks for the achievement of the benefits of protection. Connectivity patterns are still largely unknown worldwide. A general lack of knowledge is particularly evident for the Mediterranean Sea where few studies dealing with this topic have been carried out and some methods, c…
El cuerpo materno en la red: entre el orden de lo ?deseable? y el de lo real
2019
El estilo de vida fitness se realiza en, y a través de, un entramado subjetivo y de poder en el que circulan y se ensamblan dispositivos empresariales, terapéuticos, sanitarios y de espectacularización de los cuerpos, tendientes a inscribir la vida de la población en las tramas conflictivas de un capitalismo heterosexista, neoliberal e informacional. En dicho marco, la temporalidad, metamorfosis y plasticidad del cuerpo materno irrumpe como problema y objeto de intervención de tecnologías diversas orientadas a ajustar su tamaño, forma y devenir a los parámetros de la vida activa y saludable. En escenarios digitales, dicha tensión se materializa, por un lado, a través de dispositivos visuale…
"Ludzka krotochwila" na scenie teatru świata w twórczości Mikołaja Reja i Marcina Bielskiego
2019
Artykuł jest próbą interpretacji dzieł Mikołaja Reja i Marcina Bielskiego w kategoriach encyklopedycznego teatru. Taka konstrukcja stanowi odwzorowanie obrazu ówczesnego świata. Można mówić o zgodności między uczonymi treściami a wielką machiną theatrum mundi, którego struktury, relacje i zakres sprawnie funkcjonują w zamkniętym dyskursie literackich utworów. „Krotochwila ludzka” staje się więc miejscem zmagań człowieka z własnymi słabościami i losem. Staropolscy pisarze, aby zilustrować tę walkę, posłużyli się popularnym w renesansie mitem o bogini Kirke i jej ofiarach zamienionych w zwierzęta. Maski faunistyczne stanowiły znakomite alegorie występków ludzkich, chociaż mogły również przeds…
Family and work-related risk factors in children's social–emotional well-being and parent–educator cooperation in flexibly scheduled early childhood …
2023
Non-standard work schedules (NSWS) have become typical, but their associations with childcare arrangements and children's well-being are unknown. This study explores how risk factors are associated with the social–emotional well-being of girls and boys using flexibly scheduled early childhood education and care. Furthermore, the study investigates whether well-functioning cooperation between parents and educators buffers the negative effects of the risk factors. This study, which is a part of a larger survey carried out in three European countries, reports Finnish parents' (N = 146) perspectives. The results showed that high parental stress was associated with low child well-being. Strong p…
Anther culture in Citrus clementina: a way to regenerate tri-haploids
2005
Abstract. Regenerants from anther culture of Citrus clementina Hort. ex Tan. cvv. Nules, SRA 63, and Monreal were obtained in different experiments from 1994 to 2002. Genetic analysis of 37 such regenerants was carried out using 4 microsatellite markers that were heterozygous in the parental genotypes. The results showed that in all cases but one the regenerants carried only one or the other allele of the parental genotype, and were therefore homozygous and produced through a process of gametophytic embryogenesis. Ploidy analysis by flow cytometry of 94 regenerants showed that as many as 82% of them were tri-haploids, rather than haploids or doubled-haploids as expected, with other ploidy …
Agri-Food Markets towards Sustainable Patterns
2020
In recent decades, the confluence of different global and domestic drivers has led to progressive and unpredictable changes in the functioning and structure of agri-food markets worldwide. Given the unsustainability of the current agri-food production, processing, distribution and consumption patterns, and the inadequate governance of the whole food system, the transition to sustainable agriculture and food systems has become crucial to effectively manage a global agri-food market able in supporting expected population growth and ensuring universal access to sufficient, safe, and nutritious food for all. Based on a critical review of the existing international literature, the paper seeks to…
