Public social science in Norway: Migration research in the public debate

How do Norwegian migration and diversity researchers experience and maneuver participation in public debate? And do their experiences and strategies fit with Michael Burawoy's image of Norwegian social science and with his model of public sociology? In this article, the concept of public sociology is expanded to public social science, encompassing communication of research not just from sociology but social science in general. Semi-structured interviews with 31 Norwegian migration and diversity scholars from 10 academic institutions about their experiences of, and views on, public research communication constitute the empirical material. The article concludes that Burawoy is right about the relatively high participation in public debate among social scientists in Norway. And his ideal-typical distinction between four types of sociology is helpful in analyzing how researchers relate differently to the science-public interface. Yet the results indicate that his perspective on public sociology is overly optimistic and not sufficiently attuned to the normativity already attached to highly politicized issues in public debate.     

Settlement size and fertility in the Nordic countries

While the variation in childbearing patterns across countries and between socio-economic groups within a country has been studied in detail, less is known about the differences in fertility patterns across settlements within a country. Using aggregate and individual-level register data, we examine fertility variation across settlements in Denmark, Finland, Norway, and Sweden. We observe a significant variation in fertility level by settlement size in all four of these Nordic countries - the larger the settlement, the lower the fertility. Second, the variation in fertility level has decreased over time, but significant differences in fertility between settlements of different size persist. Third, the timing of childbearing also varies across settlements - the larger the settlement, the later the peak of fertility. Fourth, our analysis of parity-specific fertility in Sweden shows that the major socio-economic characteristics of women account for only a small portion of fertility variation across settlements.     

Family relations, adjustment and well-being in a longitudinal study of children in care

The article reports on a longitudinal study of children placed in a children's home during the first two years of the 1980s. The 26 children placed when younger than 4 years of age and staying more than 4 weeks were followed up 3 and 9 months after leaving the children's home and 5, 10, 15 and 20 years later. The children's family relations, including early attachments and later parental relationships and the perception of who is their family, have been one of the predominant themes in the recurrent studies. None of them had lived with both parents after leaving the children's home and 20 of them had been in foster care for periods or permanently. At the time of the last study the children were young adults, aged 20–25. They are categorized in three rather distinct categories, one for those with a ‘good’ and one for those with a ‘moderate’ social adjustment and well‐being and one for those with a ‘bad’ social adjustment and well‐being insofar as involvement with drugs, criminal behaviour and legal sanctions are concerned. Their contacts and relationships with birth parents and foster parents and the perception of who is their family are analysed by use of attachment theory and developmental psychopathology.     

Consequences of Eye Color,Positioning, and Head Movement for Eye‐Tracking Data Quality in Infant Research

Eye tracking has become a valuable tool for investigating infant looking behavior over the last decades. However, where eye‐tracking methodology and achieving high data quality have received a much attention for adult participants, it is unclear how these results generalize to infant research. This is particularly important as infants behave different from adults in front of the eye tracker. In this study, we investigated whether eye physiology, positioning, and infant behavior affect measures of eye‐tracking data quality: accuracy, precision, and data loss. We report that accuracy and precision are lower, and more data loss occurs for infants with bluish eye color compared to infants with brownish eye color. Moreover, accuracy was lower for infants positioned in a high chair or in the parents' lap compared to infants positioned in a baby seat. Finally, precision decreased and data loss increased as a function of time. We highlight the importance of data quality when comparing multiple groups, as differences in data quality can affect eye‐tracking measures. In addition, we investigate how two different measures to quantify infant movement influence eye‐tracker data quality. These findings might help researchers with data collection and help manufacturers develop better eye‐tracking systems for infants.     

RISK AVERSION RELATES TO COGNITIVE ABILITY: PREFERENCES OR NOISE?

Recent experimental studies suggest that risk aversion is negatively related to cognitive ability. In this paper we report evidence that this relation may be spurious. We recruit a large subject pool drawn from the general Danish population for our experiment. By presenting subjects with choice tasks that vary the bias induced by random choices, we are able to generate both negative and positive correlations between risk aversion and cognitive ability. Our results suggest that cognitive ability is related to random decision making rather than to risk preferences. (JEL: C81, C91, D12, D81)     

The Native‐Immigrant Income Gap among the Self‐Employed in Sweden

During recent years we have observed that non‐western immigrants are overrepresented among the self‐employed in Sweden. A reason for this might be the difficulties faced by immigrants in the labour market. The unemployment rate among non‐western immigrants in Sweden is higher than among natives with similar human capital characteristics. While this is a well‐established result, we do not know much about how self‐employed immigrants perform economically compared to their native counterparts. The purpose of this paper is to describe and analyse the incomes of self‐employed immigrants and natives in Sweden. We will also discuss possible explanations for the income gap we find. We use Swedish register data for the period 1998 to 2002 and the population studied consists of individuals who have been continuously self‐employed during this period. By performing the analysis on this group of self‐employed we get a measure of the difference among the long‐term self‐employed. The outcome of interest is the average income over the period. Income regressions are estimated using both OLS and quantile regressions. We find that self‐employed immigrants receive significantly lower incomes than their native counterparts when controlling for individual characteristics, industry and start‐up year of the firm. The income gap is larger for non‐western immigrants than for western immigrants. Quantile regressions show that the native‐immigrant income gap is smaller at the top than at the bottom of the income distribution. Several possible explanations for the native‐immigrant income gap are discussed. One possible explanation is that immigrants have a lower reservation wage and accepts staying in business receiving a lower income than comparable natives. Another explanation might be that there is discrimination against self‐employed immigrants that will lead to lower incomes. There can be consumer discrimination or discrimination from banks and real estate owners.     

Fatigue effects of noise on aeroplane mechanics

Subjective fatigue and reaction time performance were measured in a group of 24 aeroplane mechanics, during 1 week of high noise exposure and 1 week of low noise exposure. Subjective ratings were collected before and after each work day. On the last day of each week subjects also completed a reaction time task before and after work. The mechanics felt more sleepy and less energetic during the high noise week. This effect was most evident towards the end of the day and there was a build-up of the effect during the week. Reaction times were prolonged during the high noise week. Possible confounding factors are discussed and found to be less likely explanations of the effects.     

Some statistical aspects of methods for detection of turning points in business cycles

Methods for online turning point detection in business cycles are discussed. The statistical properties of three likelihood-based methods are compared. One is based on a Hidden Markov Model, another includes a non-parametric estimation procedure and the third combines features of the other two. The methods are illustrated by monitoring a period of the Swedish industrial production. Evaluation measures that reflect timeliness are used. The effects of smoothing, seasonal variation, autoregression and multivariate issues on methods for timely detection are discussed.     

Monitoring cyclical processes. A non-parametric approach

Forecasting the turning points in business cycles is important to economic and political decisions. Time series of business indicators often exhibit cycles that cannot easily be modelled with a parametric function. This article presents a method for monitoring time-series with cycles in order to detect the turning points. A non-parametric estimation procedure that uses only monotonicity restrictions is used. The methodology of statistical surveillance is used for developing a system for early warnings of cycle turning points in monthly data. In monitoring, the inference situation is one of repeated decisions. Measurements of the performance of a method of surveillance are, for example, average run length and expected delay to a correct alarm. The properties of the proposed monitoring system are evaluated by means of a simulation study. The false alarms are controlled by a fixed median run length to the first false alarm. Results are given on the median delay time to a correct alarm for two situations: a peak after two and three years respectively .
