The Uniqueness of Teaching and Learning Chemistry

2009

Unfortunately, the current perception of Chemistry held by many students and the general public alike appears to be in stark contrast to its true nature. Although chemistry is ubiquitous in all aspects of our daily lives it continues to be perceived as highly theoretical and of little relevance. A clearer understanding of the fundamental Nature of Chemistry will be needed if students are to recognize its true importance and character. It is not possible to fully understand, and as a consequence accept on an intuitive basis, the 'mystery' and fascinations arising from the transformation of matter, without first adopting a convincing sub-microscopic view, able to connect observed macroscopic …

Diritti dei bambini, diritti delle famiglie. Promuovere e formare le “capacità” genitoriali

2020

The paper focuses on the reasons for the link between children's rights and family rights, in order to highlight that parenting educational competences are challenging risk factor in contexts of poverty and always decisive factor for the actual promotion of the rights of children and adolescents. More precisely, firstly the passages of of the Convention in which the necessity of the family is argued as primary context of children's rights. Secondly, it will be problematized the very idea of ​​children's rights in the light of the "capability approach". On this basis, it will be asked whether, from a pedagogical point of view, the family can, as a whole, be the holder of a right to education…

Diritti per l’educazione. Contesti e orientamenti pedagogici

2020

The book focuses on the Convention on the Right of child as the result of a slow historical, cultural and in particular pedagogical path of progressive discovery of the specific dignity of childhood and adolescence. It is argue that, even if nowadays, more than thirty years after the drafting of the Convention, the attention to the intrinsic dignity of boys and girls, may seem indisputable and obvious, however such an attention is an achievement for a small part of the world and, also woth regard to the so-called advanced society, one might wonder to what extent and in what contexts, the twentieth century was the century of children and what is really, in the century we are living, the care…

An integrated approach based on Life Cycle Assessment and Thermoeconomics: Application to a water-cooled chiller for an air conditioning plant

2018

Abstract A large number of methods for energy systems analysis were developed in the last decades, aimed at acquiring an in-depth understanding of plant performances and enabling analysts to identify optimal design and operating conditions. In this work an integrated approach based on Life Cycle Assessment and Thermoeconomics is proposed as a method for assessing the exergo-environmental profile of energy systems. The procedure combines the capabilities of these two techniques, to account simultaneously for aspects related to thermodynamics of energy conversion processes and to the overall impacts along the plant life cycle related to other phases, i.e. from raw material extraction to the d…

Analyzing Regional Geographic Challenges: The Resilience of Chinese Vineyards to Land Degradation Using a Societal and Biophysical Approach

2021

Land degradation, especially soil erosion, is a societal issue that affects vineyards worldwide, but there are no current investigations that inform specifically about soil erosion rates in Chinese vineyards. In this review, we analyze this problem and the need to avoid irreversible damage to soil and their use from a regional point of view. Information about soil erosion in vineyards has often failed to reach farmers, and we can affirm that to this time, soil erosion in Chinese vineyards has been more of a scientific hypothesis than an agronomic or environmental concern. Two hypotheses can be presented to justify this review: (i) there are no official and scientific investigations on viney…

Searching for a hidden charm h(1) state in the X(4660) -> eta h(1) and X(4660) -> eta D*(D)over-bar* decays

2013

We explore the possibility of experimentally detecting a predicted h(1) inverted right perpendicular I-G(J(PC)) = 0(-)(1(+-))inverted left perpendicular state of hidden charm made out from the D*(D) over bar* interaction. The method consists in measuring the decay of X(4660) into eta D*(D) over bar* and determining the binding energy with respect to the D*(D) over bar* threshold from the shape of the D*(D) over bar* invariant mass distribution. A complementary method consists in looking at the inclusive X(4660) -> eta X decay and searching for a peak in the X invariant mass distribution. We make calculations to determine the partial decay width of X(4660) -> eta h(1) from the measured X(466…

Religious Engagement and the Migration Issue: Towards Reconciling Political and Moral Duty

2020

The increasingly acknowledged post-secular perspective has resulted in the emergence of some new approaches theorizing this phenomenon. One such approach has been the concept of religious engagement, which calls for the redefinition of the perception of religious non-state actors towards including them as important partners in the process of identifying and realizing political goals. According to this view, due to the multidimensional role played by religious communities and non-state religious actors, they need to be recognized as pivotal in creating a new form of knowledge generated through encounter and dialogue of the political decision-makers with these subjects. Among numerous others,…

Características y visibilidad de las revistas españolas de ciencias de la salud en bases de datos

2015

Se describen las características de 207 revistas españolas de ciencias de la salud activas en 2014 y su visibilidad en seis bases de datos biomédicas y multidisciplinares. Scopus e Ibecs son las bases de datos que mayor número de revistas cubren, y Medline y WoS las que menos. La disciplina mejor representada es medicina, seguida de psicología, enfermería y farmacia. Se observa la práctica ausencia de revistas editadas exclusivamente en papel, la existencia de revistas publicadas en inglés, el aumento de versiones bilingües español-inglés y el acceso gratuito a los contenidos. El artículo incorpora el censo de revistas, que puede servir de referencia para los investigadores para selecciona…

Characterisation of clayey raw materials for ceramic manufacture in ancient Sicily

2011

Abstract It is well known that mineralogical, petrographic and chemical analyses can successfully support provenance studies of archaeological ceramics. The characterisation of a ceramic paste, the assessment of its technology of production and its provenance assignment related to a specific production centre or to a geographical and/or compositional space, are all tasks that can be performed even more accurately if the clayey raw materials used in pottery production are also studied. For that reason the identification of the clay deposits exploited in a given ceramic workshop often plays a key role in the archaeometric reconstruction of the production cycle where geology, mineralogy, petro…
