- BACKGROUND: Particulate air pollution affects cardiovascular and pulmonary disease and mortality. A main hypothesis about the mechanisms involved is that particles induce inflammation in lower airways, systemic inflammation and oxidative stress. OBJECTIVES: To examine whether short-term exposure to wood smoke in healthy subjects affects markers of pulmonary inflammation and oxidative stress. METHODS: 13 subjects were exposed first to clean air and then to wood smoke in a chamber during 4-hour sessions, 1 week apart. The mass concentrations of fine particles at wood smoke exposure were 240-280 mug/m(3), and number concentrations were 95 000-180 000/cm(3), about half of the particles being ultrafine (<100 nm). Blood and breath samples were taken before and at various intervals after exposure to wood smoke and clean air and examined for exhaled nitric oxide and Clara cell protein in serum and urine, and malondialdehyde in exhaled breath condensate. RESULTS: Exposure to wood smoke increased alveolar nitric oxide 3 hours post-exposure while malondialdehyde levels in breath condensate were higher both immediately after and 20 hours after exposure. Serum Clara cell protein was increased 20 hours after exposure. CONCLUSIONS: Wood smoke at levels that can be found in smoky indoor environments caused an inflammatory response and signs of increased oxidative stress in the respiratory tract, especially in the lower airways.

Being employed by a co-national : A cul-de-sac or a short cut to the main road of the labour market?
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Self-employment is very common among some immigrant groups in Sweden and many of them hire co-nationals in their firms. One reason might be that they want to give newly arrived co-nationals the possibility to earn an income. But what are the consequences for the employees of being employed by a co-national? This paper analyzes the impact on labour income and future employment prospects of being employed by self-employed co-nationals shortly after arrival to Sweden. We find that immigrants in this group have substantially lower incomes than newly arrived immigrants with other forms of employment. We also find that they are less likely to work as employees in the private sector (other than being employed by a self-employed) in the future and are much more likely to become self-employed.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Vi har jämfört övergången från arbetslöshet till osubventionerat och subventionerat arbete, utbildning och arbetsmarknadsutbildning för en grupp nyanlända invandrare som slumpmässigt valts ut för att delta i en försöksverksamhet. Försöket, som syftar till att förkorta tiden fram till inträde på arbetsmarknaden, bedrevs vid arbetsförmedlingar i Stockholms, Kronobergs och Skåne län. Gruppen jämfördes med en slumpmässigt utvald kontrollgrupp bestående av nyanlända som skrivits in vid samma arbetsförmedling under samma tidsperiod. Vi finner att sannolikheten att övergå till osubventionerat arbete, senast 15 månader efter inskrivning, i genomsnitt är omkring 4 procentenheter högre för deltagare i försöket.

TIPping the Scales towards Greater Employment Chances? Evaluation of a Trial Introduction Program (TIP) for Newly-Arrived Immigrants based on Random Program Assignment
- 2009
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- A Trial Introduction Program (TIP) for newly-arrived immigrants to Sweden was set up in October 2006 in order to meet the main criticisms directed at existing introduction programs. Two primary innovations were introduced, flexible language instruction parallelwith other labor market activities at the Public Employment Service (PES) and intensive counselling and coaching by PES caseworkerswith considerably reduced caseloads. Within participating municipalities, newly-arrived immigrants were randomly assigned into TIP or the control group, i.e., regular introduction programs. Results indicate small but significant treatment effects on the probability of attaining regular employment and subsidized employment. In addition,TIP participants were considerably more likely to enter intermediate PES training programs. Hazard rates into PES training programs were also significantly higher for participants in TIP in comparison to participants in regular introduction programs.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- A Trial Introduction Program (TIP) for newly-arrived immigrants to Sweden was implemented from October 2006 to June 2008 in order to meet the main criticisms directed at existing introduction programs. Two primary innovations were introduced, flexible language instruction parallel with other labor market activities at the Public Employment Service (PES) and intensive counseling and coaching by PES caseworkers with considerably reduced caseloads. Within participating municipalities, newly-arrived immigrants were randomly assigned into TIP (treatment) or regular introduction programs (control). Results indicate significant treatment effects on the probability of attaining regular employment as well as the probability of entering intermediate PES training programs. Hazard rates into PES training programs were also significantly higher for participants in TIP in comparison to participants in regular introduction programs.
