Tidskriftsartikel (refereegranskat)abstract
- Global impact models represent process-level understanding of how natural and human systems may be affected by climate change. Their projections are used in integrated assessments of climate change. Here we test, for the first time, systematically across many important systems, how well such impact models capture the impacts of extreme climate conditions. Using the 2003 European heat wave and drought as a historical analogue for comparable events in the future, we find that a majority of models underestimate the extremeness of impacts in important sectors such as agriculture, terrestrial ecosystems, and heat-related human mortality, while impacts on water resources and hydropower are overestimated in some river basins; and the spread across models is often large. This has important implications for economic assessments of climate change impacts that rely on these models. It also means that societal risks from future extreme events may be greater than previously thought.

A research agenda for tourism geographies
- 2019
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- In recent years, tourism geographies have developed into a vibrant field of research at the intersection of geography and tourism studies. The book presents a unique collection of individual research agendas aiming to inspire the pursuit of new avenues of research. Although there have been arguments to apply post-disciplinary perspectives within tourism research, this book highlights the interest and potential of tourism geographers to contribute to a geographical tradition and influence the future content of geography as a discipline.

Tidskriftsartikel (refereegranskat)abstract
- This explorative study aims to gain more insight into Swedish-Iranians' purchase of second homes in Turkey. The study is based on 22 questionnaires (19 of them from owners and buyers), field observation, and participant observation. Motives behind owners' and buyers' purchases are: other Swedish-Iranian friends/relatives bought there; cultural proximity; absence of visa restriction for Iranian citizens; geographical proximity to Iran and relatives living in Iran; economic factors, including the low prices and costs and investment for retirement; and the climate. The respondents are well-integrated into Swedish society and have access to different types of resources which facilitate the purchase, but they also show the potential to partially become integrated socioculturally into their Turkish communities. A meaningful proportion of them are seriously planning to live permanently in Turkey after retirement, but the majority stay there for longer periods or semi-permanently. Despite some limitations, this study makes an important contribution to the area of diaspora second-home tourism and to the field of diaspora studies.

Second Home purchase in Turkey by Swedish Iranians : An Explorative Study
- 2017

Ingår i: 26th Nordic Symposium of Tourism and Hospitality Research October 4-6 2017, Falun, Sweden.

Konferensbidrag (refereegranskat)abstract
- Second home tourism is often discussed in the context of the western world. Other groups and their motivations, in this case people of Iranian background who are a large ethnic group in Sweden, are often neglected, although the group has shown interest in purchase of second home in Turkey.The aim of this study is to get more insight on Swedish Iranians’ purchase of second home in Turkey. 19 e-mail interviews (with Broker companies, owners, and potentially buyers) have been conducted. Also participant observation in Antalya region in June 2015 and at the exhibition of “Buying Properties Abroad” in Kista in September 2015 has been done.The interview results reveal that the Swedish Iranian second home buyers collect information through friends and relatives, various web sites, exhibitions, brokers, and real estate companies before buying apartment. Their motives have been: following other friends/relatives who bought apartments there, cultural proximity including the Turkish language and food, geographic proximity to Iran, relatives living in Iran do not need Turkish visa, economic factors including prices, the climate, and investment for the retirement. They stay in their apartments at least once a year up to 4 times a year and the duration of their stay each time is at least one week. A part of them might choose to live partly or permanently in Turkey after the retirement. Their motives are similar to many other second home owners elsewhere but there are also aspects related to the political context of this mobility.

Long-range angular correlations on the near and away side in p-Pb collisions at root S-NN=5.02 TeV

Tidskriftsartikel (refereegranskat)abstract
- Angular correlations between charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV for transverse momentum ranges within 0.5 < P-T,P-assoc < P-T,P-trig < 4 GeV/c. The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and expressed as associated yield per trigger particle. Two long-range ridge-like structures, one on the near side and one on the away side, are observed when the per-trigger yield obtained in low-multiplicity events is subtracted from the one in high-multiplicity events. The excess on the near-side is qualitatively similar to that recently reported by the CMS Collaboration, while the excess on the away-side is reported for the first time. The two-ridge structure projected onto azimuthal angle is quantified with the second and third Fourier coefficients as well as by near-side and away-side yields and widths. The yields on the near side and on the away side are equal within the uncertainties for all studied event multiplicity and p(T) bins, and the widths show no significant evolution with event multiplicity or p(T). These findings suggest that the near-side ridge is accompanied by an essentially identical away-side ridge. (c) 2013 CERN. Published by Elsevier B.V. All rights reserved.

Measurement of prompt J/psi and beauty hadron production cross sections at mid-rapidity in pp collisions at root s=7 TeV
- 2012

Ingår i: Journal of High Energy Physics. - 1029-8479. ; :11

Tidskriftsartikel (refereegranskat)abstract
- The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at root s = 7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L-int = 5.6 nb(-1). The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p(t) > 1,3 GeV/c and rapidity vertical bar y vertical bar < 0.9. The cross section for prompt J/psi mesons, i.e. directly produced J/psi and prompt decays of heavier charmonium states such as the psi(2S) and chi(c) resonances, is sigma(prompt J/psi) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 8.3 +/- 0.8(stat.) +/- 1.1 (syst.)(-1.4)(+1.5) (syst. pol.) mu b. The cross section for the production of b-hadrons decaying to J/psi with p(t) > 1.3 GeV/c and vertical bar y vertical bar < 0.9 is a sigma(J/psi <- hB) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 1.46 +/- 0.38 (stat.)(-0.32)(+0.26) (syst.) mu b. The results are compared to QCD model predictions. The shape of the p(t) and y distributions of b-quarks predicted by perturbative QCD model calculations are used to extrapolate the measured cross section to derive the b (b) over bar pair total cross section and d sigma/dy at mid-rapidity.

Underlying Event measurements in pp collisions at root s=0.9 and 7 TeV with the ALICE experiment at the LHC
- 2012
-
Ingår i: Journal of High Energy Physics. - 1029-8479. ; :7
-
Tidskriftsartikel (refereegranskat)abstract
- We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

Footprints of an invisible population : second-home tourism and its heterogeneous impacts on municipal planning and housing markets in Sweden
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- While public administrative systems are based on a principle of permanent residence, many people use multiple dwellings, such as second homes, in their everyday life. This mismatch makes second-home tourists an invisible population in the eyes of these systems, when, for example, distributing tax revenues or planning public services. The present thesis investigates the effects of this mismatch and its spatially diverse outcomes. It does so by studying how Swedish municipalities perceive and manage the impacts of second-home tourism, and how this tourism affects the housing market. The thesis is based on microdata of the Swedish second-home stock, longitudinal housing market statistics for 1999-2017, and interviews with civil servants from 20 Swedish municipalities.The empirical findings show that the impacts of second-home tourism vary spatially, but also over time. While all municipalities interviewed in the thesis experienced second-home tourism, there were noticeable spatial variations in the effects on, for example, planning, public services and housing provision. The patterns to this variation were particularly pronounced between periurban areas, sparsely populated areas and tourism hotspots. Periurban municipalities were most affected with second homes being converted into primary residences and the associated costs of that change. In sparsely populated areas, municipalities faced the opposite situation combined with an ever-shrinking population of permanent residents. Tourism hotspots had to manage the combined challenges of a seasonally varying second-home population exceeding the registered permanent population. The examined housing market statistics show a similar pattern, with considerable spatial differences in the market relations between primary residences and second homes. It also reveals growing regional disparities, with second homes driving or trailing overall price development depending on geographical context.To summarise, the thesis demonstrates how impacts of second-home tourism on municipal planning and housing markets differ and provides an analysis for the patterns of this variation. Based on this, it provides a number of proposals for policy change. The thesis also contributes to theory development on the spatially heterogeneous effects of mobile lifestyles, by conceptualising second-home tourism as an umbrella concept. As such, second-home tourism encompasses many different forms of dwellings, practices and impacts grounded in geographical and historical contexts. This emphasises the need for research, planning, governance and policy-making to recognise human mobility and the diverse spatiality of its effects.
