Can the environment be an inferior good? A theory with context-dependent substitutability and needs
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Theoretical models often assume the environment to be a normal good, irrespective of one’s income. However, a priori, nothing prohibits an environmental good from being normal for some individuals and inferior for others. We develop a conceptual framework in which private consumption and an environmental public good act as substitutes or complements for satisfying different needs. Subsequently, the environment can switch between normal and inferior depending on one’s income and environment. If the environment is inferior for some range of income, then the willingness to pay for environmental preservation becomes non-monotonic, thereby having implications for benefit transfers.

From Culture to Text to Interactive Visualization of Wine Reviews

Bokkapitel (refereegranskat)abstract
- On the basis of a large corpus of wine reviews, this chapter proposes a range of interactive visualization techniques that are useful for linguistic exploration and analysis of lexical, grammatical and discursive patterns in text. Our visualization tool allows linguists and others to make comparisons of visual, olfactory, gustatory and textual properties of different wines for example from different countries, from different grape varieties, or from different vintages. It also supports the visual exploration of sensory descriptions as well as confirmatory investigations of text and discourse. Besides a more technical discussion of our visualization approach, we also provide a more general overview of text and corpus visualizations and highlight linguistic challenges that we had to address during the development phase.

The shrubland vegetation in western Shewa, Ethiopia and its possible recovery
- 1991

Ingår i: Journal of Vegetation Science. - : Wiley. - 1100-9233 .- 1654-1103. ; 2:2, s. 173-180

Tidskriftsartikel (refereegranskat)abstract
- Shrubland vegetation and environmental data in western Shewa, Ethiopia have been analysed. Vegetation data include cover-abundance values of vascular plant species; en- vironmental data comprise physical and chemical properties of the soil, altitude, slope, grazing and browsing pressure.The vegetation data were subjected to hierarchical and non-hierarchical classification and ordination with correspondence analysis. The classification resulted in seven different vegetation types, ranging from grassland with scattered shrubs to degen- erated forest. Ordination of the data and biplot analysis showed that the vegetation is influenced by anthropogenic factors and altitudinal variation. Sand content is related to a low level of anthropogenic influence whereas silt content is related to a high level. This is explained by historical events rather than by the present situation. Total nitrogen, organic carbon, altitude and slope are positively correlated and these variables are negatively related to anthropogenic influences.The shrubland vegetation may have expanded from lower altitudes and drier sites as forests gradually disappeared.The recovery of an economically more rewarding vegetation type may be achieved through providing alternative sources of fuel and construction and through prohibiting cultivation and grazing in the shrublands on the hillsides. Regeneration can be accelerated by actively introducing seedlings of tree species that do not need a heavy canopy cover for establishment and growth.

Framväxten av obligatoriska som. (The development towards obligatory som.)
- 1997

Ingår i: Studier i svensk språkhistoria 4.. - 918676246X ; , s. 171-178
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In modern Swedish, the complementizer som must not be omitted in (restrictive) relative clauses when the relativised constituent is the subject. This was, however, possible in Old Swedish. Also in today's Swedish, again in contrast to Old Swedish, the complementizer som must follow a subject wh-pronoun in embedded clauses.In this paper, it is argued that the development towards obligatory som is connected with other changes in Early Modern Swedish. The investigation of a very limited number of historical texts confirms the hypothesis, particularly concerning the relatives, in the sense that the changes coincide in time. Regarding the interrogatives, however, the picture is somewhat more complex.
