Statistical methods for adaptive river basin management and monitoring

2018

Decision-making at different phases of adaptive river basin management planning rely largely on the information that is gained through environmental monitoring. The aim of this thesis was to develop and test statistical assessment tools presumed to be particularly useful for evaluating existing monitoring designs, converting monitoring data into management information and quantifying uncertainties. River basin scale monitoring was performed using a wireless sensor network and a data quality control system and maintenance effort was assessed. National-scale, traditional monitoring data and linear mixed effect modelling were used to estimate the uncertainty in two status class metrics (total …

Lay definitions of happiness across nations: The primacy of inner harmony and relational connectedness

2016

In well-being research the term happiness is often used as synonymous with life satisfaction. However, little is known about lay people's understanding of happiness. Building on the available literature, this study explored lay definitions of happiness across nations and cultural dimensions, analyzing their components and relationship with participants' demographic features. Participants were 2799 adults (age range = 30-60, 50% women) living in urban areas of Argentina, Brazil, Croatia, Hungary, India, Italy, Mexico, New Zealand, Norway, Portugal, South Africa, and United States. They completed the Eudaimonic and Hedonic Happiness Investigation (EHHI), reporting, among other information, th…

Sustainability Assessment of Agricultural Systems in Paraguay: A Comparative Study Using FAO’s SAFA Framework

2019

Sustainability is a topic that is at the center of current discussions in the political, economic, social, and environmental fields. For its analysis, an integral and multidisciplinary vision is needed. This work aims to assess the sustainability of agricultural systems in Paraguay through a comparison applying SAFA (Sustainability Assessment of Food and Agriculture Systems) indicators. The research focuses on 15 case studies on the territory of the Eastern Region of Paraguay divided into five classes of agricultural systems: agribusiness, conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture. Data were collected through in…

Teacher students’ meaningful learning in widening learning worlds

2019

This qualitative metasynthesis investigated students’ meaningful learning experiences amid andragogical teacher education programmes. The programmes catered to the specific learning needs of adult students in the context of university-based teacher education. This study aimed to provide a wider picture of the frames of students’ meaningful learning in andragogical teacher education programmes. The findings revealed three major learning worlds of adult students’ meaningful learning, which formed a common system widening from the professional awakening to the transformative community and agency in society. Based on the findings, this study argues that in andragogical teacher education, which …

Photodegradation of Brilliant Green Dye by a Zinc bioMOF and Crystallographic Visualization of Resulting CO2

2021

We present a novel bio-friendly water-stable Zn-based MOF (1), derived from the natural amino acid L-serine, which was able to efficiently photodegrade water solutions of brilliant green dye in only 120 min. The total degradation was followed by UV-Vis spectroscopy and further confirmed by single-crystal X-ray crystallography, revealing the presence of CO2 within its channels. Reusability studies further demonstrate the structural and performance robustness of 1.

New Microbe Killers : Self-Assembled Silver(I) Coordination Polymers Driven by a Cagelike Aminophosphine

2019

New Ag(I) coordination polymers, formulated as [Ag(μ-PTAH)(NO3)2]n (1) and [Ag(μ-PTA)(NO2)]n (2), were self-assembled as light- and air-stable microcrystalline solids and fully characterized by NMR and IR spectroscopy, electrospray ionization mass spectrometry (ESI-MS(±), elemental analysis, powder (PXRD) and single-crystal X-ray diffraction. Their crystal structures reveal resembling 1D metal-ligand chains that are driven by the 1,3,5-triaza-7-phospaadamantane (PTA) linkers and supported by terminal nitrate or nitrite ligands; these chains were classified within a 2C1 topological type. Additionally, the structure of 1 features a 1D!2D network extension through intermolecular hydrogen bonds…

Reading data from graphs: a study on the role of language.

2015

International audience; The work described in this paper is framed in a larger study focused on written argumentations produced by university students in tasks regarding graphs, conversions between graphs and their analytic properties and relations among different graphs. Using the functional linguistics framework, we analyse difficulties related to an examination task on functions and their derivatives. The use of colloquial and literate registers in mathematics problem solving is the lens through which we analyse and discuss the errors. We draw attention to the difficulties concerning the use of literate registers and how these difficulties influence the errors in the interpretations of t…

Towards Automatic Testing of Reference Point Based Interactive Methods

2016

In order to understand strengths and weaknesses of optimization algorithms, it is important to have access to different types of test problems, well defined performance indicators and analysis tools. Such tools are widely available for testing evolutionary multiobjective optimization algorithms. To our knowledge, there do not exist tools for analyzing the performance of interactive multiobjective optimization methods based on the reference point approach to communicating preference information. The main barrier to such tools is the involvement of human decision makers into interactive solution processes, which makes the performance of interactive methods dependent on the performance of huma…

Critical thinking skills in classe tra sfida e impegno

2020

A scuola devono essere previsti ed attuati interventi sistematici che promuovano negli alunni abilità quali l’uso corretto di ragionamenti, la formulazione adeguata di giudizi, la generazione e l’espressione di idee originali, lo sviluppo di ipotesi per la soluzione di problemi, la costruzione di piani d’azione, l’assunzione di scelte autonome e controllate. L’espansione tecnologica alimenta piuttosto la difficoltà di bambini e ragazzi di organizzare i dati conoscitivi provenienti da più fonti, di selezionare e valutare le informazioni secondo scopi definiti. Si tratta di identificare azioni educative e procedure didattiche efficaci ad impegnare la capacità critica degli alunni. Il contesto…
