Pathways of urban nature : diversity in the greening of the twenty-first century city

Nature is a central component of the twenty-first-century city. Beyond parks and open spaces, urban nature is implicated in strategies of economic development, climate change mitigation and adaptation, public art, biodiversity enhancement, local food production, health and livability, social justice, community identity, and more.1 This “pluralization” of urban nature has come about in the last four

The politics of urban experiments : realising radical change or reinforcing business as usual?

When Jean-Francois Mayet was elected mayor of the French city of Châteauroux in 2001, he inherited a mass transit system that was functional but under-used by residents. The city, located about halfway between Paris and Bordeaux, had collective aims that were similar to other medium-sized cities in Europe: to reduce the city’s ecological footprint while improving the local economy and fostering a

Expertise : specialised knowledge in environmental politics and sustainability

The dominant role of technology in contemporary societies requires the public to rely on individuals with specialized knowledge to invent, design, manufacture, and maintain increasingly complex artifacts and networks. As Stilgoe et al. ( 2006 : 16) note, “Our everyday lives are played out through a series of technological and expert relationships.” In spite of the increasing reliance on technologi

Living laboratories for sustainability : exploring the politics and epistemology of urban transition

Creating a more sustainable society is increasingly an urban challenge (Pincetl 2010). Upwards of 50 per cent of the world’s population currently dwell in cities, and this figure is forecast to rise dramatically over the coming decades (Grimm et al. 2008). Cities both concentrate the activities that produce carbon emissions, and suffer disproportionately from their negative impacts such as air pol

Technical expertise, sustainability, and the politics of knowledge

The dominant role of technology in contemporary societies requires the public to rely on individuals with specialized knowledge to invent, design, manufacture and maintain increasingly complex artifacts and networks. As Stilgoe et al. (2006: 16) note, “Our everyday lives are played out through a series of technological and expert relationships.” In spite of the increasing reliance on technologies

Match Theory : An overview

This paper introduces Match Theory, an Optimality-Theoretic approach to the syntax–phonology interface proposed by Selkirk (2011). The theory states that a family of Match constraints favor syntax–prosody isomorphism, but that these can be outranked by constraints on prosodic wellformedness and/or information structure, resulting in certain principled mismatches. We compare Match Theory to previou

Simultaneous immunohistochemistry and autoradiography of peptides and 5-hydroxytryptamine in bird retina

A method was developed for the simultaneous demonstration of two specific cellular constituents. Cryostat sections of formaldehyde fixed tissue from retinae treated with ((3)H)-5-hydroxytryptamine were subjected to immunohistochemistry and subsequent autoradiography. The method takes advantage of the very efficient and specific uptake mechanism that many types of neurons possess which makes it pos

Taxonomy, saving potentials and key performance indicators for energy end‐use and greenhouse gas emissions in the aluminium industry and aluminium casting foundries

Increasing energy efficiency within the industrial sector is one of the main approaches in order to reduce global greenhouse gas emissions. The production and processing of aluminium is energy and greenhouse gas intensive. To make well‐founded decisions regarding energy efficiency and greenhouse gas mitigating investments, it is necessary to have relevant key performance indicators and information

Effects on primary energy use, greenhouse gas emissions and related costs from improving energy end-use efficiency in the electrolysis in primary aluminium production

Primary aluminium production is energy- and GHG-intensive in which electrolysis is by far the most energy- and GHG-intensive process. This paper’s aim is to study the effects on (1) primary energy use, (2) GHG emissions and (3) energy and CO2 costs when energy end-use efficiency measures are implemented in the electrolysis. Significant savings in final and primary energy use, GHG emissions and ene

Barriers to and drivers for improved energy efficiency in the Swedish aluminium industry and aluminium casting foundries

Industrial energy efficiency is important for reducing CO2 emissions and could be a competitive advantage for companies because it can reduce costs. However, cost-effective energy efficiency measures are not always implemented because there are barriers inhibiting their implementation. Drivers for energy efficiency could provide means for overcoming these barriers. The aim of this article was to s

Energy efficiency in the supply chains of the aluminium industry : The cases of five products made in Sweden

Improved energy efficiency in supply chains can reduce both environmental impact and lifecycle costs, and thus becomes a competitive advantage in the work towards a sustainable global economy. Viewing the supply chain as a system provides the holistic perspective needed to avoid sub-optimal energy use. This article studies measures relating to technology and management that can increase energy eff

Energy efficient supply chain of an aluminium product in Sweden - What can be done in-house and between the companies?

According to the Energy Efficiency Directive executed by the European Union, each member state is obliged to set a national target on energy efficiency. This requirement constitutes the basis for governments to formulate policy measures directed towards industrial companies. Such policy measures, along with the demand for cost-effective production to remain competitive on the market, motivates ind

Review of measures for improved energy efficiency in production-related processes in the aluminium industry – From electrolysis to recycling

The aluminium industry is facing a challenge in meeting the goal of halved greenhouse gas emissions by 2050, while the demand for aluminium is estimated to increase 2–3 times by the same year. Energy efficiency will play an important part in achieving the goal. The paper's aim was to investigate possible production-related energy efficiency measures in the aluminium industry. Mining of bauxite and

A quest for roots and kinship : Family history in the television series Allt för Sverige (The Great Swedish Adventure)

This paper considers the contemporary significance of family history and, more generally, cross-national heritage by studying a Swedish television programme in which Swedish Americans visit Sweden to find out more about their ancestors and possibly to meet present-day relatives. Saar’s theory of three levels of genealogy—history, evaluation, and genre—is used as the analytical framework. The findi

Phonology in Swedish-speaking 5-year-olds born with unilateral cleft lip and palate and the relationship with consonant production at 3 years of age

PURPOSE: At ∼3 years of age ∼50% of the children born with cleft palate present with phonological/articulatory difficulties. Differences between children with and without cleft palate have been reported to decline with age; however, the phonology in children with cleft palate at pre-school age/early school age has rarely been explored. The purpose of this study was to assess phonology in children

Some Early Christian Trees

In the wake of the current environmental crisis, scholars of late antique Christianity are beginning to study Christian attitudes towards the natural world. How did the early Christians relate to their environment? This article explores perceptions of trees, surveying the writings of Tertullian, Basil of Caesarea, and Sozomen the historian. What did an arboreal plant do, according to patristic aut
