Covariate Order Tests for Covariate Effect

A new approach for constructing tests for association between a random right censored life time variable and a covariate is proposed. The basic idea is to first arrange the observations in increasing order of the covariate and then base the test on a certain point process defined by the observation times. Tests constructed by this approach are robust against outliers in the covariate values or misspecification of the covariate scale since they only use the ordering of the covariate. Of particular interest is a test based on the Anderson-Darling statistic. This test has good power properties both against monotonic and nonmonotonic dependencies between the covariate and the life time variable.     

Many a slip between cup and lip. Process evaluation of a program to promote and support evidence-based public health practice

The main aims of this study are to document whether an intervention for promoting evidence-based public health practice had been delivered as intended and to explore the reasons for its lack of impact. Process data from the implementation of the program and data from interviews with 40 public health physicians are analyzed. Although they expressed satisfaction with the service, the doctors experienced the program as rather irrelevant for their daily work. They did not perceive that they dealt with many issues relevant for the use of research information, and if they did, referring to research would not make any difference to the way others perceived their advice. There is a need to develop more overlying strategies for integrating evidence into decision making than addressing the individual level.     

Investigating suburban micromoth diversity using DNA barcoding of malaise trap samples

Micromoths can be challenging to identify based on morphology and are frequently omitted in assessments of moth diversity. However, their species richness and biology make them important components of terrestrial ecosystems. In this study we identified 1227 micromoths from a suburban garden at 63° north using DNA barcoding of Malaise trap samples. We recorded 78 different species with the 11 most abundant taxa accounting for 82 % of the catch. The remaining 67 species were represented by fewer than 14 specimens, but the number was often sufficient to provide a good idea of phenology. The larvae of these 78 species all feed on plants common in suburban environments. We show that when facilitated by identifications through DNA barcoding, Malaise traps provide interesting insights into the micromoth communities of suburban environments that might otherwise be overlooked. The use of Malaise traps is beneficial for investigations at high latitudes where light trapping is inefficient for sampling moths due to bright summer nights.     

“I Vow to Thee My Countries” – The Expansion of Dual Citizenship in the 21st Century

Global developments in dual citizenship legislation highlight changes to conceptualizations of citizenship by increasing the focus on individual rights. Questions of inclusion and exclusion have been illuminated by the move toward wider acceptance of dual citizenship. To understand global patterns and developments in dual citizenship laws this article analyzes the legislation pertaining to dual citizenship in 115 countries. The results show how dual citizenship is becoming increasingly accepted – a development that has predominantly taken place within the last 20 years. A strong regional pattern is identified, supporting the argument that dual citizenship is spreading in a fashion similar to how the idea of citizenship expanded from Europe in the 19th and 20th centuries. Potential internal and external reasons for this development are discussed and individual countries’ experiences analyzed.     

A Conditional Variance Model for Daily Deviations of an Exchange Rate

A model for the distribution of daily deviations of an exchange rate is suggested. The distribution is Gaussian with a variance that depends on previous deviations. The model is applied to the exchange rate of the U.S. dollar to special drawing rights.     

Models of social mobility

Properties of measures and models of social mobility are analyzed in relation to the conceptualization of mobility. Two main objectives of mobility research are identified. One is the study of determinants of occupational achievement, the other is the study of mobility as a characteristic of social systems. It is shown that the realization of both objectives is hindered by a failure of commonly used models and measures of mobility to separate out the various individual and structural factors responsible for mobility.     

Unemployed by choice: young creative people and the balancing of responsibilities through strategic self-management

The Danish welfare system inadvertently provides a good opportunity for young creative people to pursue their dreams in creative fields such as art, acting, music while being on unemployment benefits. As Michael, one of the participants, puts it: ‘I consider unemployment benefit entrepreneurial support’. The subversive practice is illegal. This qualitative study investigates how young unemployed people who choose to be unemployed in order to engage in innovative projects in creative fields understand and justify their practice. Analysis of in-depth interviews with six young unemployed persons shows how the understanding and management of responsibility is pivotal in the self-understanding and legitimization of receiving unemployment benefits by choice, not out of need. This creative group reflects the contours of a new type of unemployed that has received very little attention in the research literature. The group challenges the traditional representation of the unemployed and portrays themselves as innovative, competent and able to cope with financial insecurity even though it is psychologically distressing and a risky path to go down. We characterize them as strategic self-managing as they use educational systems and unemployment benefit systems for something entirely different from what they are intended – they use it to create their own artistic life courses. This study tentatively points to a categorization distinguishing between personal, social and societal responsibility by which we can improve our understanding of responsibility in neoliberal contexts.     

Parents’ economic support of young-adult children: do socioeconomic circumstances matter?

We assess how the support parents provide to young adults as they leave school and begin working is related to their family’s socioeconomic circumstances. We do this using an innovative Australian data set which merges survey and administrative data. The survey data inform us about intergenerational co-residence and financial gifts and the administrative data about the family’s welfare receipt history. We find that disadvantaged young people are more likely to be economically independent of their parents than are their more advantaged peers. This disparity is larger for financial gifts than for co-residence and increases with age. Moreover, there is a complex relationship between parental support and participation in study and work. We find no evidence, however, that a lack of parental support is the source of the socioeconomic gradient in either studying or employment. These results are important in eliminating one potential pathway through which socioeconomic disadvantage limits young people’s outcomes.
