Does it pay off to specialize? The interplay between educational specificity, level and cyclical sensitivity.

This paper investigates how the specificity of the field of study is related to the quality of school-to-work transitions, and whether this relation is moderated by the level of education and the cyclical sensitivity of the field of study. We apply a processual approach and produce a typology of school-to-work transitions based on labor market position and income. This is done with multichannel sequence analysis on register data on school-leavers in the Netherland for the 2009-2010 cohort (N = 182,057). The results confirm that specificity is positively related to the quality of school-to-work transitions in terms of employment and income security. This however mostly holds for the highest levels of upper-secondary vocational education (ISCED 354), and much less for the lower levels of upper-secondary vocational education and tertiary education. In contrast to our expectations, specificity was more often related to positive career outcomes for cyclically sensitive fields of study.

The long-run effects of secondary school track assignment.

This study analyzes the long-run effects of secondary school track assignment for students at the achievement margin. Theoretically, track assignment maximizes individual outcomes when thresholds between tracks are set at the level of the indifferent student, and any other thresholds would imply that students at or around the margin are better off by switching tracks. We exploit non-linearities in the probability of track assignment across achievement to empirically identify the effect of track assignment on educational attainment and wages of students in the Netherlands, who can be assigned to four different tracks. We find that attending higher tracks leads to increases in years of schooling by around 1.5 years for students at the lowest and the highest choice margin, and wage gains of around 15% and 5%, respectively. For the margin between the two middle tracks, attending the higher of the two tracks has no effect on educational attainment and decreases wages by around 12%. The negative returns for the medium margin and the relatively low returns for the higher margin (compared to the required educational investments) are partly mediated by motivation and study choice.

Measuring upper limb capacity in patients after stroke: reliability and validity of the stroke upper limb capacity scale.

OBJECTIVE: To investigate the interrater reliability and construct validity of the Stroke Upper Limb Capacity Scale (SULCS). DESIGN: Cohort study. SETTING: Inpatient department of a rehabilitation center. PARTICIPANTS: Patients after stroke (N=21; mean age ± SD, 61.7 ± 7.9y; 57% men), undergoing inpatient rehabilitation. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The SULCS was administered by occupational therapists (OTs) within 6 weeks after stroke (t1), 3 months after t1 by the same OT (t2), and within 1 week after t2 by another OT (t3). Interrater reliability, the repeatability between different raters, was assessed by calculating the intraclass correlation coefficient (ICC) based on the scores at t2 and t3. Construct validity, indicating agreement with hypotheses concerning the construct that is being measured, was assessed with Spearman rank correlation coefficient (ρ). The SULCS scores were cross-sectionally correlated with those of the Action Research Arm Test (ARAT) and the Rivermead Motor Assessment (RMA) at t1, and longitudinally with the respective change scores between t1 and t2. RESULTS: The SULCS (range, 0-10) had a high ICC (.94; 95% confidence interval, .86-.97) and strong cross-sectional correlation with both the ARAT and the RMA (ρ=.91 and ρ=.85, respectively), while the respective change scores showed a strong correlation with the ARAT (ρ=.71) and a moderate correlation with the RMA (ρ=.48). CONCLUSIONS: The SULCS has good interrater reliability and construct validity.

Measuring upper limb capacity in poststroke patients: development, fit of the monotone homogeneity model, unidimensionality, fit of the double monotonicity model, differential item functioning, internal consistency, and feasibility of the stroke upper limb capacity scale, SULCS.

OBJECTIVES: To develop an easy-to-use scale that measures upper limb capacity, according to the International Classification of Functioning, Disability and Health definition, in patients after stroke, and to investigate certain psychometric properties of this scale. DESIGN: Cohort study. SETTING: Inpatient department of a rehabilitation center. PARTICIPANTS: Patients (N=546; mean age ± SD, 60.1±11.2y; 56% men) undergoing rehabilitation after stroke. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Mokken scale analysis was used to investigate the following psychometric properties: (1) fit of the monotone homogeneity model, indicating that the items form a scale; (2) unidimensionality, indicating that the items measure only 1 concept (or construct); (3) fit of the double monotonicity model, indicating invariant (hierarchical) item ordering; (4) differential item functioning (DIF), indicating the validity of comparison between subgroups; and (5) internal consistency, indicating the degree of interrelatedness of the items. The mean time needed to complete the scale was calculated to indicate (6) feasibility. RESULTS: The Stroke Upper Limb Capacity Scale (SULCS) was developed on the basis of interviews with experts. Ten of 15 items had (1) good fit of the monotone homogeneity model (coefficient H=.88), were (2) unidimensional, and had (3) good fit of the double monotonicity model (coefficient H(T)=.71), (4) absence of DIF (Crit-values <40), and (5) good internal consistency (coefficient ρ=.96). When applying start-and-stop rules, the (6) feasibility of the SULCS was good (6min). CONCLUSIONS: The SULCS is an easy-to-use, unidimensional, hierarchical, and internally consistent scale that assesses upper limb capacity in patients after stroke.
