Role of labor demand in the labor market effects of a pension reform
This paper shows that labor demand plays an important role in the labor market reactions to a pension reform in Germany. Employers with a high share of older worker inflow compared with their younger worker inflow, employers in sectors with few investments in research and development, and employers in sectors with a high share of collective bargaining agreements allow their employees to stay employed longer after the reform. These employers offer their older employees partial retirement instead of forcing them into unemployment before early retirement because the older employees incur low substitution costs and high dismissal costs
A short isoform of STIM1 confers frequency-dependent synaptic enhancement
Store-operated Ca2+-entry (SOCE) regulates basal and receptor-triggered Ca2+ signaling with STIM proteins
sensing the endoplasmic reticulum (ER) Ca2+ content and triggering Ca2+ entry by gating Orai channels.
Although crucial for immune cells, STIM1’s role in neuronal Ca2+ homeostasis is controversial. Here, we
characterize a splice variant, STIM1B, which shows exclusive neuronal expression and protein content surpassing conventional STIM1 in cerebellum and of significant abundance in other brain regions. STIM1B
expression results in a truncated protein with slower kinetics of ER-plasma membrane (PM) cluster formation
and ICRAC, as well as reduced inactivation. In primary wild-type neurons, STIM1B is targeted by its spliced-in
domain B to presynaptic sites where it converts classic synaptic depression into Ca2+- and Orai-dependent
short-term synaptic enhancement (STE) at high-frequency stimulation (HFS). In conjunction with altered
STIM1 splicing in human Alzheimer disease, our findings highlight STIM1 splicing as an important regulator
of neuronal calcium homeostasis and of synaptic plasticity
Early retirement of employees in demanding jobs: Evidence from a German pension reform
Early retirement options are usually targeted at employees at risk of not reaching their regular retirement age in employment. An important at‐risk group comprises employees who have worked in demanding jobs for many years. This group may be particularly negatively affected by the abolition of early retirement options. To measure differences in labor market reactions of employees in low‐ and high‐demand jobs, we exploit the quasi‐natural experiment of a cohort‐specific pension reform that increased the early retirement age for women from 60 to 63 years. Based on a large administrative dataset, we use a regression‐discontinuity approach to estimate the labor market reactions. Surprisingly, we find the same relative employment increase of about 25% for treated women who were exposed to low and to high job demand. For older women in demanding jobs, we also do not find substitution effects into unemployment, partial retirement, disability pension, or inactivity. Eligibility for the pension for women required highlabor market attachment; thus, we argue that this eligibility rule induced a positive selection of healthy workers into early retirement

Long-term Effects of Multimodal Treatment on Adult Attention-Deficit/Hyperactivity Disorder Symptoms Follow-up Analysis of the COMPAS Trial
IMPORTANCE Knowledge about the long-term effects of multimodal treatment in adult attention-deficit/hyperactivity disorder (ADHD) is much needed. OBJECTIVE To evaluate the long-term efficacy of multimodal treatment for adult ADHD. DESIGN, SETTING, AND PARTICIPANTS This observer-masked, 1.5-year follow-up of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), a prospective, multicenter randomized clinical trial, compared cognitive behavioral group psychotherapy (GPT) with individual clinical management (CM) and methylphenidate (MPH) with placebo (2 x 2 factorial design). Recruitment started January 2007 and ended August 2010, and treatments were finalized in August 2011 with follow-up through March 2013. Overall, 433 adults with ADHD participated in the trial, and 256 (59.1%) participated in the follow-up assessment. Analysis began in November 2013 and was completed in February 2018. INTERVENTIONS After 1-year treatment with GPT or CM and MPH or placebo, no further treatment restrictions were imposed. MAIN OUTCOMES AND MEASURES The primary outcome was change in the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score from baseline to follow-up. Secondary outcomes included further ADHD rating scale scores, observer-masked ratings of the Clinical Global Impression scale, and self-ratings of depression on the Beck Depression Inventory. RESULTS At follow-up, 256 of 433 randomized patients (baseline measured in 419 individuals) participated. Of the 256 patients participating in follow-up, the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score was assessed for 251; the mean (SD) baseline age was 36.3 (10.1) years; 125 patients (49.8%) were men; and the sample was well-balanced with respect to prior randomization (GPT and MPH: 64 of 107; GPT and placebo: 67 of 109; CM and MPH: 70 of 110; and CM and placebo: 55 of 107). At baseline, the all-group mean ADHD Index of Conners Adult ADHD Rating Scale score was 20.6, which improved to adjusted means of 14.2 for the GPT arm and 14.7 for the CM arm at follow-up with no significant difference between groups (difference, -0.5; 95% CI, -1.9 to 0.9; P=.48). The adjusted mean decreased to 13.8 for the MPH arm and 15.2 for the placebo arm (difference, -1.4; 95% CI, -2.8 to -0.1; P=.04). As in the core study, MPH was associated with a larger reduction in symptoms than placebo at follow-up. These results remained unchanged when accounting for MPH intake at follow-up. Compared with participants in the CM arm, patients who participated in group psychotherapy were associated with less severe symptoms as measured by the self-reported ADHD Symptoms Total Score according to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) (DSM-IV) of Conners Adult ADHD Rating Scale (AMD, -2.1; 95% CI, -4.2 to -0.1; P=.04) and in the subscale of reducing pure hyperactive symptoms, measured via the Diagnostic Checklist for the diagnosis of ADHD in adults (AMD, -1.3; 95% CI, -2.8 to 0.1; P=.08). Regarding the Clinical Global Impression scale assessment of effectiveness, the difference between GPT and CM remained significant at follow-up (odds ratio, 1.63; 95% CI, 1.03-2.59; P=.04). No differences were found for any comparison concerning depression as measured with the Beck Depression Inventory. CONCLUSIONS AND RELEVANCE Results from COMPAS demonstrate a maintained improvement in ADHD symptoms for adults 1.5 years after the end of a 52-week controlled multimodal treatment period. The results indicate that MPH treatment combined with GPT or CM provides a benefit lasting 1.5 years. Confirming the results of the core study, GPT was not associated with better results regarding the primary outcome compared with CM. TRIAL REGISTRATION isrctn.org Identifier: ISRCTN5409620
