- This study evaluates a Swedish version of the Voice Handicap Index adapted for singers. A total of 96 healthy singers and 30 singer-patients completed the questionnaire. Validity and reliability, internal coherence, and group differences were assessed. The singer- patient group had significantly higher scores than the control group. Reliability was confirmed by high Cronbach's (> 0.78) for test-retest scores, and for each of the sub-scales. Test-retest stability in both groups was confirmed by high correlation values alpha (> 0.8). Overall scores compared closely to those from previous reports. The Swedish translation of the adapted VHI for singers (RHI-s) is valid and reliable and shows sensitivity to the singer's concerns. It can be considered a useful tool in the clinical assessment of Swedish healthy or pathological singers.

- Studien belyser hur gymnasielärare retrospektivt uppfattar att de förberetts för sitt yrke under lärarutbildningen. Enkätsvar från 1554 gymnasielärare kategoriserades efter den tidsperiod då de examinerades. Frågan om hur väl förberedda de nyexaminerade lärarna var för sitt yrke kopplas till de nationella reformer som styrde lärarutbildningen under den period som läraren studerade. Medan utbildningen i praktisk yrkeskunskap uppfattas ha försämrats över tid, har andra områden förbättrats. Lärosäte hade inte något samband med respondenternas svarsmönster. Slutsatsen är att utbildningsreformerna har samband med förändringar i utbildningens måluppfyllelse, att förbereda lärarstudenter för sitt yrke, samt att utbildningens anpassning till yrkets krav försämrats över tid.

- This paper introduces quality of government rather than regime type as dependent variable in studies of political effects of natural resources. It consists of two parts. First, it argues for an effect of fiscal dependency of oil and gas rents on quality of government. Second, it finds significant, negative effects of oil and gas rent dependency on three empirical indicators of quality of government-low corruption, bureaucratic quality and legal impartiality-in a sample of 139 states in the period 1984-2006. The results hold for inclusion of control variables such as regime type, income, region and religion.

Children with borderline intellectual functioning and autism spectrum disorder : developmental trajectories from 4 to 11 years of age
- 2017

Ingår i: Neuropsychiatric Disease and Treatment. - 1176-6328 .- 1178-2021. ; 13, s. 2519-2526

Tidskriftsartikel (refereegranskat)abstract
- Background: Studies on autism have tended to focus either on those with intellectual disability (ie, those with intellectual quotient [IQ] under 70) or on the group that is referred to as high-functioning, that is, those with borderline, average or above average IQ. The literature on cognition and daily functioning in autism spectrum disorder combined specifically with borderline intellectual functioning (IQ 70-84) is limited. Methods: From a representative group of 208 preschool children diagnosed with autism spectrum disorder, those 50 children in the group with borderline intellectual functioning at ages 4.5-6.5 years were targeted for follow-up at a median age of 10 years. A new cognitive test was carried out in 30 children. Parents were interviewed with a semi-structured interview together with the Vineland Adaptive Behavior Scales (n=41) and the Autism-Tics, attention-deficit/hyperactivity disorder (AD/HD) and other comorbidities inventory (A-TAC) (n=36). Results: Most children of interviewed parents presented problems within several developmental areas. According to A-TAC and the clinical interview, there were high rates of attention deficits and difficulties with regulating activity level and impulsivity. Vineland Adaptive Behavior Scales composite scores showed that at school age, a majority of the children had declined since the previous assessment at ages between 4.5 and 6.5 years. Almost half the tested group had shifted in their IQ level, to below 70 or above 84. Conclusion: None of the children assessed was without developmental/neuropsychiatric problems at school-age follow-up. The results support the need for comprehensive follow-up of educational, medical and developmental/neuropsychiatric needs, including a retesting of cognitive functions. There is also a need for continuing parent/family follow-up and support.

Tidskriftsartikel (refereegranskat)abstract
- The study presents neuropsychiatric profiles of children aged 11 with autism spectrum disorder, assessed before 4.5 years, and after interventions. The original group comprised a community sample of 208 children with ASD. Parents of 128 participated-34 with average intellectual function, 36 with borderline intellectual function and 58 with intellectual disability. They were interviewed using the Autism-Tics, AD/HD and other Comorbidities interview. Criteria for a clinical/subclinical proxy of ASD were met by 71, 89 and 95 %, respectively. Criteria for at least one of ASD, AD/HD, Learning disorder or Developmental Coordination Disorder were met by 82, 94 and 97 %. More than 90 % of children with a preschool diagnosis of ASD have remaining neuropsychiatric problems at 11, despite early intervention.

Is there Really a Unit Root in the Inflation Rate? More Evidence from Panel Data Models
- 2008
-

Tidskriftsartikel (refereegranskat)abstract
- Time series unit root evidence suggests that inflation is nonstationary. By contrast, when using more powerful panel unit root tests, Culver and Papell (1997) find that inflation is stationary. In this article, we test the robustness of this result by applying a battery of recent panel unit root tests. The results suggest that the stationarity of inflation holds even after controlling for cross-sectional dependence and structural change.

Panel cointegration and the monetary exchange rate model
- 2009

Tidskriftsartikel (refereegranskat)abstract
- This paper re-examines the validity of the monetary exchange rate model during the post-Bretton Woods era for 18 OECD countries. Our analysis simultaneously considers the presence of both cross-sectional dependence and multiple structural breaks, which have not received much attention in previous studies of the monetary model. The empirical results indicate that the monetary model emerges only when the presence of structural breaks and cross-country dependence has been taken into account. Evidence is also provided suggesting that the breaks in the monetary model can be derived from the underlying purchasing power parity relation. (C) 2008 Elsevier B.V. All rights reserved.

A Non-Stationary Panel Data Investigation of the Unemployment–Crime Relationship
- 2014
-
Ingår i: Social Science Research. - : Elsevier BV. - 0049-089X. ; 44, s. 114-125
-
Tidskriftsartikel (refereegranskat)abstract
- Many empirical studies of the economics of crime focus solely on the determinants thereof, and do not consider the dynamic and cross-sectional properties of their data. As a response to this, the current paper offers an in-depth analysis of this issue using data covering 21 Swedish counties from 1975 to 2010. The results suggest that the crimes considered are non-stationary, and that this cannot be attributed to county-specific disparities alone, but that there are also a small number of common stochastic trends to which groups of counties tend to revert. In an attempt to explain these common stochastic trends, we look for a long-run cointegrated relationship between unemployment and crime. Overall, the results do not support cointegration, and suggest that previous findings of a significant unemployment–crime relationship might be spurious.

Panel bootstrap tests of slope homogeneity

Tidskriftsartikel (refereegranskat)abstract
- This paper proposes two bootstrap-based tests that can be used to infer whether the individual slopes in a panel regression model are homogenous. The first test is suitable when wanting to infer the null of homogeneity versus the general alternative, while the second is suitable when wanting to infer the units of the panel that can be pooled. Both approaches are shown to be asymptotically valid, a property that is verified in small samples using Monte Carlo simulation.

Testing slope homogeneity in large panels with serial correlation
- 2013
-
Ingår i: Economics Letters. - : Elsevier BV. - 0165-1765. ; 121:3, s. 374-378
-
Tidskriftsartikel (refereegranskat)abstract
- Pesaran and Yamagata (Pesaran, M.H., Yamagata, T., Testing slope homogeneity in large panels, Journal of Econometrics 142, 50–93, 2008) propose a test for slope homogeneity in large panels, which has become very popular in the literature. However, the test cannot deal with the practically relevant case of heteroskedastic and/serially correlated errors. The present note proposes a generalized test that accommodates both features.
