Abstract. The new PAGES2k global compilation of temperature-sensitive proxies offers an unprecedented opportunity to study regional to global trends associated with orbitally driven changes in solar irradiance over the past 2 millennia. Here, we analyze pre-industrial long-term trends from 1 to 1800 CE across the PAGES2k dataset and find that, in contrast to the gradual cooling apparent in ice core, marine, and lake sediment data, tree rings do not exhibit the same decline. To understand why tree-ring proxies lack any evidence of a significant pre-industrial cooling, we divide those data by location (high Northern Hemisphere latitudes vs. midlatitudes), seasonal response (annual vs. summer)…

Crystals and the debates on the nature, recognition and origin of life

Heating glaciers from below

2013

Climate change is affecting the cryosphere from above. Geothermal heat flux from below is also contributing to conditions at the base of Greenland's ice sheet, which sits atop a lithosphere of variable thickness.

Photovoice—Towards Engaging and Empowering People with Intellectual Disabilities in Innovation

2020

E-health and welfare technology offer new ways to support health and social care delivery. While initiatives are made to engage disadvantaged user groups in innovation, people with intellectual disabilities tend to be excluded from design activities. This is a concern as this group can benefit from the use of assistive technology. However, it can be time-consuming and challenging to involve end-users in the design of technology. This calls for processes that are creative, empowering and that facilitate user involvement. In this study, we report and reflect on the process of using photovoice to understand user needs and to empower participants with intellectual disability in an innovation pr…

Integrating risk management tools for regional forest planning: an interactive multiobjective value-at-risk approach

2018

In this paper, we present an approach employing multiobjective optimization to support decision making in forest management planning under risk. The primary objectives are biodiversity and timber cash flow, evaluated from two perspectives: the expected value and the value-at-risk (VaR). In addition, the risk level for both the timber cash flow and biodiversity values are included as objectives. With our approach, we highlight the trade-off between the expected value and the VaR, as well as between the VaRs of the two objectives of interest. We employ an interactive method in which a decision maker iteratively provides preference information to find the most preferred management plan and le…

Evaluating a hierarchical approach to landscape-level harvest scheduling

2018

Forest planning at the landscape level has the potential to become a large intractable problem. In Finland, Metsähallitus (the state enterprise that manages federally owned land) creates strategic plans to determine the appropriate harvest level. While these plans are feasible, they are not implementable in practice as the harvests are scattered temporally and spatially. Requiring that harvests be organized both temporally and spatially for practical implementation can result in an intractable problem. Through a hierarchical approach, the problem can be organized into steps in which the intractable problem is broken down into smaller easily solvable parts. As an approximation technique, th…

Una segregazione paradossale e multi-scalare: il caso del quartiere ZEN di Palermo

2016

L’articolo affronta la questione della segregazione nel quartiere ZEN di Palermo (Sicilia). L’impianto teorico dialoga con la letteratura anglosassone, ma ne prende le distanze nel tentativo di individuare alcune specificità locali del caso. L’obiettivo è duplice: intanto indentificare alcuni “movimenti geostorici” che hanno caratterizzato il quartiere, collegando a ciascuno di questi una fase del processo segregativo; inoltre, rappresentare la segregazione del quartiere in forma cartografica, mediante l’uso di alcuni ideogrammi e mappe mentali. This article deals with the issue of segregation in the ZEN district of Palermo, Sicily. The theoretical framework is built around Anglo-Saxon refe…

Place names as evocative elements of historical landscape. Analysis of urban place names in the Vinalopó Basin

2017

La cuenca del Vinalopó, al sur del País Valenciano, está compuesta por una serie de comarcas industriales densamente pobladas que han sido habitadas desde la Antigüedad. Aprovechando la perspectiva diacrónica que ofrecen los nombres de lugar, se reconstituyen virtualmente ciertos elementos naturales y culturales del paisaje histórico de la comarca del Vinalopó mediante un análisis toponímico basado en elucidar la etimología de los nombres de lugar, en el método de observación de los rasgos geográficos de dichos lugares y en las fuentes históricas que se refieren a los mismos. The Vinalopó basin, in the south of the Valencian Community (Spain), is composed of densely populated industrial tow…

Material Deprivation: a Case of Latvia

2021

Material deprivation has recently gained prominence as a topic of debate as its proliferation is raising throughout Europe in particular in the countries hit hardest by financial and economic turbulences what leads to the gap in material deprivation levels throughout Europe. The aim of the study is to analyze material deprivation in the regions of Latvia. Research methods used in preparation of the paper: scientific publication and previous conducted research results analysis, analysis of anonimised data of EU-SILC survey results and European Central Bank conducted survey on Household income and expenses survey results, results are compared with the results of other EU countries. Survey ano…

India’s Turn to Rights-Based Legislation (2004–2014): A Critical Review of the Literature

2018

This article surveys the academic literature on rights-based legislation and critically discusses key findings and arguments that emerge from this literature. I conduct this survey and discussion in light of a wider understanding of the political economy of Indian democracy as resilient but limited in terms of substantial forms of redistribution and recognition in favour of subaltern groups. This contradiction has arguably become especially pronounced in the context of neoliberalisation, where, despite the active participation of the poor in electoral democracy, socioeconomic inequality has reached dramatic heights, and I discuss rights-based legislation as a response to this. In conclusio…
