Who am I?:Studying autobiographical reasoning, identity commitment and exploration processes, and narrative content in unison

Identity research focuses on multiple processes capturing how adolescents form and maintain a sense of self. However, identity content (the “what” of identity) might impact associations between identity and the association with well-being. We examined this potential role of content (i.e., valence and life domain) in two studies, focusing on autobiographical reasoning in written narratives (i.e., self-event connections), educational identity commitment and exploration processes, and measures of general and domain-specific functioning. Study 1 (N = 180, Mage = 14.7) and Study 2 (N = 160, Mage = 13.1) provided little evidence for the hypothesized role of identity content, but moderation analyses in Study 1 showed that self-event connections were more strongly related to life satisfaction in narratives about relational events than other events. These findings suggest a more fine-grained approach is needed to capture the role of identity content

Overt and subtle discrimination and psychological well-being:Examining the mediating and moderating role of ethnic-racial identity among emerging adults

Ethnic-racial identity (ERI) has been reported as mediator and moderator of the relation between discrimination and psychological well-being. However, it remains unclear how different forms of discrimination (i.e., overt and subtle) predict well-being over time, and whether ERI exploration and commitment mediate or moderate this association. This preregistered study explored the associations of overt and subtle discrimination with well-being (i.e., depression, substance use, life satisfaction) in a sample of 323 ethnic-racial minoritized college students (M age W1 = 18.03, 62.7% female) from longitudinal data collected in the US. Cross-lagged panel models across three waves indicated no associations of overt discrimination, but participants experiencing more subtle discrimination during their transition to college reported more depressive symptoms after four months. Ethnic-racial identity did not function as mediator or moderator. Findings indicate the need for a more nuanced understanding of the role of ERI during emerging adulthood.</p

Measurement of the longitudinal diffusion of ionization electrons in the MicroBooNE detector

Abstract: Accurate knowledge of electron transport properties is vital to understanding the information provided by liquid argon time projection chambers (LArTPCs). Ionization electron drift-lifetime, local electric field distortions caused by positive ion accumulation, and electron diffusion can all significantly impact the measured signal waveforms. This paper presents a measurement of the effective longitudinal electron diffusion coefficient, DL, in MicroBooNE at the nominal electric field strength of 273.9 V/cm. Historically, this measurement has been made in LArTPC prototype detectors. This represents the first measurement in a large-scale (85 tonne active volume) LArTPC operating in a neutrino beam. This is the largest dataset ever used for this measurement. Using a sample of ∼70,000 through-going cosmic ray muon tracks tagged with MicroBooNE's cosmic ray tagger system, we measure DL = 3.74+0.28 -0.29 cm2/s

Highly-parallelized simulation of a pixelated LArTPC on a GPU

The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The algorithms have been written in Python and translated into CUDA kernels using Numba, a just-in-time compiler for a subset of Python and NumPy instructions. The GPU implementation achieves a speed up of four orders of magnitude compared with the equivalent CPU version. The simulation of the current induced on 10^3 pixels takes around 1 ms on the GPU, compared with approximately 10 s on the CPU. The results of the simulation are compared against data from a pixel-readout LArTPC prototype

Meaning making about and across self-relevant experiences:Links with identity commitment and exploration processes and satisfaction with life in adolescence

Making meaning is an important process through which individuals keep their identity up-to-date, but has often been measured in a way that conflates dispositional, trait-like influences with narrative-specific influences. The present study aimed to disentangle these influences during adolescence by examining the general tendency for meaning making, measured as self-event connections, across three self-relevant narratives in relation to dual-cycle processes of identity commitment and exploration and satisfaction with life (N = 162, Mage = 16.2, 67.3% female). Additionally, these associations were examined separately for the different narratives and event valences. Meaning making was related to the identity processes, but was not associated with satisfaction with life. This study emphasizes the importance of both dispositional and narrative-specific approaches to meaning making.</p

Social inhibition sense of belonging and vulnerability to internalizing problems

Background The aim of this study was to provide a conceptual test of how social inhibition, sense of belonging and internalizing problems are related, and whether sense of belonging moderates or mediates the relation between social inhibition and internalizing problems. Methods Data were used from two waves of the Dutch internet cohort LISS (Longitudinal Internet Studies of the Social Sciences; N = 511, M age = 52.09 years). Social inhibition was measured using the DS14 in 2012, sense of belonging (i.e., feeling cut off and having people to really talk to) was measured with the General Social Exclusion Index in 2012 and internalizing problems with the MHI-5 in 2015. Results Social inhibition was related to a lower sense of belonging and more internalizing problems. A low sense of belonging was related to more internalizing problems. Results indicated no moderation. However, evidence was found for partial mediation. That is, feeling cut off and having people to really talk to explained part of the link between social inhibition and internalizing problems. All analyses were controlled for sex, age and income. Limitations The items used to measure sense of belonging only cover part of the construct. The study was not fully prospective, as such, no conclusions can be drawn regarding causality. Conclusions Low sense of belonging is a key factor to consider when aiming at understanding individual differences in internalizing psychopathology related to social inhibition.

Narrativiteit in vaktherapie

Voor u ligt het boek ‘Narrativiteit in vaktherapie’, voor vaktherapeuten in de praktijk. Het doel van dit praktijkboek is om de begrippen ‘narratief werken’ en ‘narratief onderzoek’ toe te lichten en deze te verbinden aan de praktijk van de vaktherapie. Door definitie en uitleg van deze begrippen wordt het begrippenkader van de vaktherapeut itgebreid. Het helpt de vaktherapeut om te toetsen in hoeverre hij/zij werkzaam is volgens narratieve principes. Daarnaast schept het voor vaktherapeuten mogelijkheden hun werkwijzen desgewenst bij te schaven. Kennis over narrativiteit draagt zo bij aan de kwaliteit van het vaktherapeutisch werkveld
