Assessing Effects of Temperature Change on Four Limonium Species from Threatened Mediterranean Salt-Affected Habitats
2018
[EN] Evaluation of tolerance to temperatures in the germination stage is an important tool to foresee the possible effect of global warming. Moreover, establishing germination protocols for endemic and threatened species is most interesting for restoration and management plans that focus on habitat conservation. Seed germination was analysed in four species of the genus Limonium (L. virgatum, L. narbonense, L. girardianum and L. santapolense) growing in two saline habitats on the eastern coast of the Iberian Peninsula. The study aim was to compare responses of seed germination to different temperature regimes. Seeds were collected in two protected areas, `L¿Albufera de Valencia¿ (province o…
Drought-related cholera outbreaks in Africa and the implications for climate change: a narrative review.
2021
ABSTRACT Africa has historically seen several periods of prolonged and extreme droughts across the continent, causing food insecurity, exacerbating social inequity and frequent mortality. A known consequence of droughts and their associated risk factors are infectious disease outbreaks, which are worsened by malnutrition, poor access to water, sanitation and hygiene and population displacement. Cholera is a potential causative agent of such outbreaks. Africa has the highest global cholera burden, several drought-prone regions and high levels of inequity. Despite this, research on cholera and drought in Africa is lacking. Here, we review available research on drought-related cholera outbreak…
The Postglacial Isotopic Record of Intermediate Water Connects Mediterranean Sapropels and Organic‐Rich Layers
2020
Carbon‐rich layers exist at both sides of the Mediterranean Sea sedimentary record and are called sapropels and organic rich layers (ORLs), respectively, in the eastern and western basins. They have different levels of organic carbon accumulation and seafloor oxygen deprivation. The most recent sapropel and ORL depositions have a different timing, approximately 10.8–6.1 and 14.5–9.0 ka, respectively. Here we investigate oxygen isotopic records of three foraminifera species that occupy different habitats within the Sicily Channel water column since ~12.0 ka, thus in the sill between the eastern and western Mediterranean basins. These data are ice volume corrected, to get information on water…
Superparameterised cloud effects in the EMAC general circulation model (v2.50) – influences of model configuration
2020
A new module has been implemented in the fifth generation of the ECMWF/Hamburg (ECHAM5)/Modular Earth Submodel System (MESSy) Atmospheric Chemistry (EMAC) model that simulates cloud-related processes on a much smaller grid. This so-called superparameterisation acts as a replacement for the convection parameterisation and large-scale cloud scheme. The concept of embedding a cloud-resolving model (CRM) inside of each grid box of a general circulation model leads to an explicit representation of cloud dynamics. The new model component is evaluated against observations and the conventional usage of EMAC using a convection parameterisation. In particular, effects of applying different configurat…
Unequal access to food during the nutritional transition: evidence from Mediterranean Spain †
2020
Unequal access to food is one of the main issues in nutritional history, but scarcity of sources has hampered the quantification of this phenomenon. This study uses hospital diets to address this gap. It uses records from between 1852 and 1923 concerning hospital diets in the psychiatric section of the Hospital General de Valencia (Spain), from which it is possible to infer the actual intake of nutrients for six groups of patients and members of staff. The results reveal considerable differences in terms of diet and nutrition. While the most favoured groups (nuns and well‐off patients) had by 1852 reduced their relative intake of cereals and increased that of meat, in line with the general …
Being a teacher and teacher educator : The antecedents of teacher educator identity among mentor teachers
2019
Access and use by the CC-BY-NC-ND user license Although teachers’ professional identities have been the subject of extensive study, the field still lacks knowledge about the development of a professional identity for mentor teachers. These teachers take on multifaceted professional roles as teachers and teacher educators. In the present paper, we investigate the professional identity of mentor teachers partnered with two universities in Norway. The study adopts a quantitative approach and report on survey data from the mentor teachers. The results demonstrate that school climate, individual beliefs about the role, and university collaboration predict the development of a teacher educator id…

Effects of school climate and teacher self-efficacy on job satisfaction of mostly STEM teachers: a structural multigroup invariance approach
2020
Abstract Background Identification and retention of effective teachers in STEM education play cardinal roles in teacher recruitment exercises worldwide. Studies on factors that characterize effective teachers have therefore gained popularity in recent times. Teacher self-efficacy, job satisfaction and school climate are among other factors that have attracted global attention. Thus, proper understanding of the relations between these factors is equally important. The purpose of this study is to validate and cross-validate a model of direct/indirect effects of school climate and teacher self-efficacy on job satisfaction. Results The data used for the current study are extracted from a public…
Energy Performance and Indoor Comfort of a 1930s Italian School Building: A case study
2021
Reducing energy consumption in the building tertiary sector, which accounts for a big share of the total energy use (and related CO 2 emissions) at European and Italian level, represent a strong element of safety for the EU-28. On the other hand, it is important to improve the, often overlooked, indoor comfort conditions of Italian schools since they have a significant impact on the well-being, productivity, health and safety of their occupants. Thus, it is appropriate to take into account the combination of both needs, also in light of the climate change scenario, in order to identify adequate improvement measures and justify such economic investment. This paper brings a contribution to th…
What Do School Children Know about Climate Change? A Social Sciences Approach
2022
One of the subject areas that is currently most prominent in the field of education (Social Science) is climate change, given its implications for raising awareness and training the present and future society. The objectives of this study, focused on school children (Primary Education—10 to 12 years old; third cycle, Secondary Education—12–16 years old; and pre-university, Baccalaureate—17–18 years old) in the Region of Valencia (Spain), are to analyse the following: the main information channels through which children receive information on climate change; the causes and consequences that they identify with respect to this phenomenon; and the main greenhouse g…
