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.

- The atomic structure and spectra of ten tungsten ions have been calculated using the Flexible Atomic Code. The calculations yield energy levels, radiative lifetimes, spectral line positions, transition probability rates, and oscillator strengths for the tungsten ions isoelectronic to germanium, W42+, through vanadium, W51+. Collisional-radiative models for high-temperature, low-density plasmas have been implemented to produce line emissivities for X-ray transitions in the 1-4 keV (3-12 angstrom) spectral interval. The Ge-like through V-like W ions are important in nuclear fusion research where their spectra may provide diagnostic information on magnetically confined plasmas. (C) 2013 Elsevier Inc.

From Culture to Text to Interactive Visualization of Wine Reviews
- 2013
-
Ingår i: Knowledge Visualization Currents<em></em>. - London : Springer. - 9781447143024 ; , s. 85-110
-
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.)

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.

Diversity-multiplexing tradeoff analysis of multi-source multi-relay coded networks

Konferensbidrag (refereegranskat)abstract
- We study the impact of efficient network coding and multiple access techniques in a two-source two-relay one-destination wireless network through the diversity-multiplexing tradeoff (DMT) analysis. We compare the standard relaying protocol without network coding and the protocols using either a binary network coding (BNC) or an appropriately designed non-binary finite-field network coding (FFNC) at the relays. It is shown that the use of the non-binary FFNC strictly outperforms the other two protocols in terms of DMT. In addition, we propose a new transmission strategy based on the non-binary FFNC design and the non-orthogonal multiple access technique to further improve the DMT performance. Our results highlight the advantages of applying appropriate network coding in multi-source multi-relay networks.

Human Resource Development in Restaurants in Western Sweden – A Human Capital Theory Perspective
- 2024

Ingår i: Journal of Human Resources in Hospitality & Tourism. - : Routledge. - 1533-2845 .- 1533-2853. ; 23:2, s. 289-314

Tidskriftsartikel (refereegranskat)abstract
- While the Swedish hospitality industry is experiencing substantial growth, this growth comes with a cost, as the industry has neither the knowledge nor the incentive to pay enough attention to human resource development. This continuous growth will therefore impose challenges and erect obstacles once the industry begins expanding again after the pandemic. Insofar as attracting, engaging and retaining talent are the biggest challenges, it might be time to go back to the drawing board and identify a possible shift to an employee-based approach to developing businesses. Based on interviews with managers and owners representing 28 predominantly seasonal restaurants in the Swedish coastal region of Bohuslän, this study identifies current obstacles and challenges facing the Swedish restaurant industry with a clear focus on the concept of human capital. The results of the study clearly indicate that human resource development (HRD) is by far the most critical factor in addressing staffing issues and overcoming the difficulty involved in attracting, engaging, and retaining not only enough staff but more importantly staff with basic knowledge, experience, and interest. The aim here is to initiate a shift to a more direct and sustained focus on human capital in the hospitality industry, from the perspective of human capital theory, by highlighting some of the most highly relevant factors associated with this perspective. According to an employee-driven restaurant analysis (EDRA) approach, a shortage of human capital could pose the biggest obstacle to further development, as restaurants find it increasingly difficult to attract, engage and retain employees for all positions.

Performance and Micro‑Pacing Strategies in Biathlon Skiing
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Purpose To examine the micro-pacing (within-lap) strategies during biathlon skiing with and without the biathlon rifle. Methods Twenty biathletes (7 women, 13 men) performed two crosscountry skiing time-trials on a ≈2300 m course, once with and once without the biathlon rifle. During time-trials, biathletes wore a sensor that recorded position, distance and skiing-speed. A trajectory correction and statistical parametric mapping procedure determined the course positions (clusters) where instantaneous skiing-speed was significantly related to time-trial performance. The time differences between the fastest and slowest skier in these clusters were calculated. Results The fastest biathletes skied with greater instantaneous speeds in specific clusters, which included both uphill and downhill sections. The clusters represented time gains for the fastest skier over the slowest skier of between 16.1 and 25.8 s for the women and between 18.9 and 21.9 s for the men. The largest time gains between the fastest and slowest biathletes were observed in a downhill section that was preceded by a 180° turn, where time gains were between 2.9 and 4.1 s in clusters of between just 12 to 62 m. In biathlon skiing with-rifle, there were more clusters that were not present during without-rifle. When skiing with-rifle, there were additional clusters in the uphill sections that represented time gains of 5.2 s and 2.3 s for the women and men, respectively. Conclusions Statistical parametric mapping can be used in biathlon to provide pacing and performance feedback to athletes and coaches.

Efficacy of the antibacterial envelope to prevent cardiac implantable electronic device infection in a high-risk population
- 2022

Tidskriftsartikel (refereegranskat)abstract
- AimsInfection is a serious complication of cardiac implantable electronic device (CIED) therapy. An antibiotic-eluting absorbable envelope has been developed to reduce the infection rate, but studies investigating the efficacy and a reasonable number needed to treat in high-risk populations for infections are limited.Methods and resultsOne hundred and forty-four patients undergoing CIED implantation who received the antibacterial envelope were compared with a matched cohort of 382 CIED patients from our institution. The primary outcome was the occurrence of local infection, and secondary outcomes were any CIED-related local or systemic infections, including endocarditis, and all-cause mortality. The results were stratified by a risk score for CIED infection, PADIT. The envelope group had a higher PADIT score, 5.9 ± 3.1 vs. 3.9 ± 3.0 (P < 0.0001). For the primary endpoint, no local infections occurred in the envelope group, compared with 2.6% in the control group (P = 0.04), with a more pronounced difference in the stratum with a high (>7 points) PADIT score, 0 vs. 9.9% (P = 0.01). The total CIED-related infections were similar between groups, 6.3% compared with 5.0% (P = 0.567). Mortality after 1600 days of follow-up did not differ between groups, 22.9 vs. 26.4%, P = 0.475.ConclusionOur study confirms the clinical efficacy of an antibacterial envelope in the prevention of local CIED infection in patients with a higher risk according to the PADIT score. In an effort to improve cost–benefit ratios, ration of use guided by the PADIT score is advocated. Further prospective randomized studies in high-risk populations are called for.

- PURPOSE: To assess the diagnostic efficacy, safety and tolerability of mangafodipir trisodium (MnDPDP, Teslascan) in MR imaging of the liver. MATERIAL AND METHODS: Eighty-two patients from 4 centres underwent MR imaging with pre-contrast sequences including T1-weighted SE and GRE, and T2-weighted turbo SE sequences. MnDPDP at a dose of 5 mumol/kg b.w. was administered by slow i.v. infusion, and 20-60 min after infusion the T1-weighted SE and GRE sequences were repeated. Diagnostic efficacy was evaluated by counting the number of lesions and by evaluating whether more information for lesion characterisation was available in post-contrast images. Safety and tolerability were assessed by recording adverse events and infusion-related discomfort. RESULTS: Significantly more lesions were found in MnDPDP-enhanced T1-weighted SE and GRE images than in unenhanced images of the same sequences. More lesions were also found in these images compared with T2-weighted images at a level of marginal significance. More information was obtained from MnDPDP-enhanced images in 40 cases. Mild to moderate adverse events were experienced by 17% of the patients. CONCLUSION: MnDPDP-enhanced images can improve lesion detection in the liver and are helpful for lesion characterisation. To obtain optimal diagnostic information of liver lesions T2-weighted images are also valuable. MnDPDP is a safe contrast agent for MR imaging of liver lesions.
