The significance of soils and soil science towards realization of the United Nations Sustainable Development Goals
2016
Abstract. In this forum paper we discuss how soil scientists can help to reach the recently adopted UN Sustainable Development Goals (SDGs) in the most effective manner. Soil science, as a land-related discipline, has important links to several of the SDGs, which are demonstrated through the functions of soils and the ecosystem services that are linked to those functions (see graphical abstract in the Supplement). We explore and discuss how soil scientists can rise to the challenge both internally, in terms of our procedures and practices, and externally, in terms of our relations with colleague scientists in other disciplines, diverse groups of stakeholders and the policy arena. To meet th…
Climate change impact on SWAT simulated streamflow in western Kenya
2008
Weather and climate extremes such as droughts and floods have far reaching impacts in Kenya. They have had implications in a variety of sectors including agriculture, water resources, health, energy, and disaster management among others. Lake Victoria and its catchment support millions of people and any impact on its ability to support the livelihoods of the communities in this region is of major concern. Thus, the main objective of this study was to assess the potential future climatic changes on the Nzoia catchment in the Lake Victoria basin, and how they might affect streamflow. The Soil and Water Assessment Tool was used to investigate the impact of climatic change on streamflow of the …
Liberty winter gardens in Palermo: contamination from solar design
2020
At the end of the 19th century, the city of Palermo boasted a tradition of steel elements that could include the most beautiful railings and light steel structures of the time. The paper shows how the technological, formal and spatial aspects of the metallic construction was derived by the application of Central Europe areas examples to the local reality, providing notions on designs, experimentations and originalities. Canopies, verandas, winter gardens and orangeries are architectural elements in iron and glass that represent an added value for the building, they improve the life quality of the people who live there. In particular, in the Liberty architecture these elements took shape thr…
Investigating the Affordances and Constraints of SimReal for Mathematical Learning : A Case Study in Teacher Education
2019
Visualizations tools are one of the most innovative technologies that emerged the last few years in educational settings. They provide new potentialities for mathematical learning by means of dynamic animations and representations, interactive simulations, and live streaming of lessons. Moreover, visualization tools have the potential to foster a visual, dynamic, distributed, and embodied mathematics rather than individual achievements and static representations. This paper uses the visualization tool SimReal in teacher education to explore the affordances of the tool for learning mathematics. It proposes a framework that captures the affordances of SimReal at a technological, pedagogical, …
Prosjektarbeid i barnehagen – mellom bekvemmelighet og medvirkning
2021
I denne artikkelen analyseres samtaler fra personalmøter i to barnehager som arbeider prosjektbasert inspirert av Reggio Emilia-pedagogikk. Observasjoner av møter er supplert med intervju med de pedagogiske lederne. Målet med undersøkelsen har vært å studere hvordan personalet snakker sammen om arbeid med prosjekt i møtene og hvordan dette kan ha betydning for barns mulighet for medvirkning. Vi viser hvordan samtalene arter seg gjennom et prosjektforløp. Underveis i denne prosessen identifiserte vi fire ulike diskurser som på ulike måter legger føringer for barnas medvirkning i arbeidet med prosjektene. Vi har kalt disse for henholdsvis en medvirkningsdiskurs, en undringsdiskurs, en bekvemm…
Levels and change in autonomous and controlled work motivation in older workers—The role of proximity to retirement and sense of community at work
2021
Previous studies suggest a preretirement disengagement process from work, which includes reduced work motivation. In this study, we investigated changes in autonomous and controlled work motivation over two years among participants of the Health, Aging and Retirement Transition in Sweden (HEARTS) study. We found stability in both types of motivation; however, those who retired after the study period showed more distinct declines in autonomous motivation. A stronger sense of community at work was related to level, but not change in autonomous motivation. Intra-individual fluctuations in the expected retirement age did not predict work motivation or vice versa. Future studies are needed to be…
The Impact of Working Memory Training on Children’s Cognitive and Noncognitive Skills
2020
Working memory capacity is thought to play an important role for a wide range of cognitive and noncognitive skills such as fluid intelligence, math, reading, the inhibition of pre-potent impulses or more general self-regulation abilities. Because these abilities substantially affect individuals' life trajectories in terms of health, education, and earnings, the question of whether working memory (WM) training can improve them is of considerable importance. However, whether WM training leads to improvements in these far-transfer skills is contested. Here, we examine the causal impact of WM training embedded in regular school teaching by a randomized educational intervention involving a sampl…
Thermo-hygrometry and IAQ Related Measurements of the Indoor Physical Conditions of Exhibition Halls for Complying International Rules and Standards
2018
Off-line methods for detecting the indoor physical parameters of museums are important tools in order of continuously monitoring the conditions at which works of art are exposed. These conditions, in fact, are mandatory established by several rules and technical standards aimed at preserving the specific artifacts. Moreover, indoor microclimate parameters must also take into account the comfort conditions for visiting people. Both the above-cited requirements suggest to perform the indoor monitoring with equipment visually low impacting. In this paper, some examples of visually low impacting off-line monitoring methods, applied to three artifacts displayed in the “Museo Regionale” of Palerm…
Spatial fragmentation of, and US support for, the main multilateral institutions of the western order
2017
The growth of China-led minilateral initiatives mostly of a regional character has challenged the main multilateral institutions of the Western order and, ultimately, US authority. Faced with a progressive delegitimation of the institutional architecture that it promoted after World War II, the US, under the Obama administration, has acted to defend the existing main multilateral institutions of the order (UN, IMF, WB and WTO), attributing them with a strategic role. More than being radical, though, the reforms enacted have been incremental and pragmatic, but always imperfect. More importantly, they have not altered US influence, which is exercised mostly through informal means. This, howev…
HOMFLY-PT skein module of singular links in the three-sphere
2012
For a ring R, we denote by [Formula: see text] the free R-module spanned by the isotopy classes of singular links in 𝕊3. Given two invertible elements x, t ∈ R, the HOMFLY-PT skein module of singular links in 𝕊3 (relative to the triple (R, t, x)) is the quotient of [Formula: see text] by local relations, called skein relations, that involve t and x. We compute the HOMFLY-PT skein module of singular links for any R such that (t-1 - t + x) and (t-1 - t - x) are invertible. In particular, we deduce the Conway skein module of singular links.
