The legacy of human use in Amazonian palm communities along environmental and accessibility gradients
2023
Aim: Palms are iconic and dominant elements of neotropical forests. In the Amazon region, palms have been used and managed by humans for food, material, medicine and other purposes for millennia. It is, however, debated to what extent the structure of modern palm communities reflects long-term human modification. Here, we investigate the complex interplay of ecological and societal factors that influence the distributions of both human-used and non-used palms in western Amazonia. Location: Amazonia. Time period: Present. Major taxa studied: Palms (Arecaceae). Methods: We used Bayesian hierarchical joint species distribution models to predict the distributions and environmental niche dimensi…
Perceived need to increase physical activity levels among adults at high risk of type 2 diabetes. A cross-sectional analysis within a community-based…
2012
Background. Increased physical activity is a cornerstone of type 2 diabetes prevention. The perception of a need to change is considered essential in behaviour change processes. However, the existing literature on individuals' perceived need to change health behaviour is limited. In order to improve understanding of diabetes prevention through increased physical activity levels (PAL), we assessed factors associated with perceiving a need to increase PAL among adults at high risk of diabetes. Methods. Opportunistic screening was used within a primary-care based lifestyle intervention covering 10 149 men and women at high risk of type 2 diabetes. Data were obtained at baseline visits. Th…
Do People Follow Jobs of Do Jobs Follow People? : The Case of Finland in an International Context
2016
Traditionally, people are believed to follow jobs; however, a contradictory view that jobs follow people has also gained popularity. In this study, two methods are used to analyze regional growth processes in Finland between 1990 and 2010, and the results are compared with the findings obtained elsewhere. In accordance with the results from many countries, the conventional regional adjustment model shows that people have largely followed jobs in Finland, i.e., that regional growth is demand induced. A closer examination suggests, however, that highly educated people drive regional change in Finland and that economic fluctuations also have an effect. Another approach, based on the Granger ca…
Posted work and deterritorialization in the European Union: a study of the German construction and meat industry
2015
Mobiliteit en burgerschaprechten binnen de Europese Unie beïnvloeden de levens van miljoenen mensen in de EU op een positieve manier. In Posted Work and Deterritorialization in the European Union betoogt Ines Wagner echter dat de dynamiek van intra-Europese arbeidsmigratie ook een hypermobiele onderklasse van arbeiders in precaire, slecht betaald werk creëert. Dit komt voornamelijk doordat tewerkstellingsstructuren transnationaliseren, terwijl beleidsinstrumenten en kiesdistricten territoriaal geregeld blijven. Wagner’s conclusies zijn gebaseerd op kwalitatief onderzoek naar detachering in de Duitse politieke economie. Gedetacheerde werknemers zijn arbeidsmigranten die door hun werkgever ti…
Experimental Constraints on the Deep Magma Feeding System at StromboliVolcano, Italy
2009
International audience; New experiments have been performed on a high-K basalt (PST-9) from Stromboli volcano, Italy, to constrain the physical conditions of golden pumice magmas at their storage level and discuss their petrogenesis. Fluid-present, H2O- and CO2-bearing, near-liquidus experiments were performed at 11508C between 100 and 400MPa and under oxidizing conditions. Glasses were analyzed by Fourier transform IR spectroscopy and their H2O and CO2 concentrations compared with those in glass inclusions.Most glass inclusions cluster near the 200MPa isobar, suggesting entrapment at a depth of ~8 km. Golden pumice magmas have viscosities of 7.9 Pa s and densities of 2.48-2.57 g/cm3. Compo…
Submerged macrophytes as key players in aquatic ecosystems under global change: a multiscale experimental approach
2020
El actual cambio global está causando alteraciones en los ecosistemas de todo el mundo a través de cambios interactivos en los principales factores ambientales (e.g. la temperatura, la concentración de nutrientes y la radiación ultravioleta). Los ecosistemas acuáticos continentales son altamente vulnerables ante estos cambios y, específicamente, en la región mediterránea, la situación es peor ya que la mayoría de estos sistemas son someros y están expuestos a las perturbaciones ambientales y antrópicas. Las praderas de macrófitos sumergidos y, particularmente, los carófitos, son un elemento conspicuo de estos sistemas con un papel fundamental en su funcionamiento. Estos organismos proveen d…
Observation of the Early Structural Changes Leading to the Formation of Protein Superstructures.
2014
Formation of superstructures in protein aggregation processes has been indicated as a general pathway for several proteins, possibly playing a role in human pathologies. There is a severe lack of knowledge on the origin of such species in terms of both mechanisms of formation and structural features. We use equine lysozyme as a model protein, and by combining spectroscopic techniques and microscopy with X-ray fiber diffraction and ab initio modeling of Small Angle X-ray Scattering data, we isolate the partially unfolded state from which one of these superstructures (i.e., particulate) originates. We reveal the low-resolution structure of the unfolded state and its mechanism of formation, hi…
Er det forskjell i barns inntak av frukt og grønnsaker og drikke ved 12, 24 eller 48 måneders alder mellom barn av mødre som har deltatt eller ikke d…
2019
Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2019 Background: Women's intake of fruits and vegetables and drinks during pregnancy can affect both mother and child health.Aim: The purpose of this study is to investigate whether the dietary intervention in pregnant women in the Fit for Delivery study has had an effect on what their child is eating and drinking at 12, 24 and 48 months of age.Method: Pregnant women were recruited up to week 20 of pregnancy and were randomized to either a control or intervention group. Participants responded to food frequencyquestionnaires at different time points. Independent sample t-tests were used to analyze the difference in intake of fru…
PROGETTARE L’ADATTAMENTO. Resilienze di agricoltura urbana nel contesto europeo
2022
I crescenti fenomeni legati al cambiamento climatico spingono le città a sviluppare piani di resilienza che possano rispondere in termini di sostenibilità ambientale, sociale ed economica. Le strategie nature-based possono rappresentare una soluzione; tra queste l’agricoltura urbana può contribuire ad aumentare la resilienza dei tessuti urbani europei. Questa attività è stata più volte oggetto di interesse in periodi di crisi come impegno comunitario dai caratteri sociali, oltre che produttivi ed educativi. Attraverso un excursus storico e una successiva analisi di casi studio contemporanei, il paper fornisce strumenti progettuali per intervenire nel costruito con strategie che spaziano dal…
Rigenerazione urbana e transizione ecologica. Il ripristino del sistema fluviale dell'Østerå come servizio ecosistemico di Aalborg (DK)
2023
I principi della Carta di Aalborg (1994) hanno ispirato e guidato la rigenerazione della città danese, sede della Prima Conferenza Europea sulle Città Sostenibili, verso un modello di sviluppo urbano sostenibile. Le politiche urbane hanno affrontato i temi della transizione energetica, del recupero delle aree urbane dismesse e della conservazione della natura e della biodiversità in una prospettiva olistica. Per aumentare la resilienza della città nei confronti dei cambiamenti climatici e per migliorare l’equilibrio ecosistemico degli ambienti urbanizzati, Aalborg ha puntato sul rafforzamento delle infrastrutture verdi e blu, avviando progetti di riattivazione dei cicli naturali interrotti …
