Preface

AimThis was a one-year follow-up of families referred to support services after the parents visited the emergency department due to intimate partner violence, substance abuse or a suicide attempt. Its aim was to evaluate the well-being of any children. MethodsData on families identified a year earlier by the Amsterdam protocol were gathered from child protective services and parent and child self-reports in two Dutch regions from 2012-2015. ResultsWe included 399 children (52%) boys with a median age of eight years (range 1-18) in the study using child protective services data. Of the 101 families who participated in the first measurement, 67 responded one year after the parent's emergency department visit. The results showed that 20% of the children had no or minor problems, voluntary support services were involved in 60% of cases and child protective services were involved in 20%. Compared to their first assessment a year earlier, the children's psychosocial problems had not increased, but this could have been an underestimation due to selective responses. ConclusionThe Amsterdam protocol was valuable in referring families to voluntary support services, but given the ongoing problems in some families, professionals need to carefully monitor whether support services are sufficiently effectiv

Theorising age and generation in development: A relational approach

This introduction outlines the analytical approach informing the articles presented in this special issue. The project of ‘generationing’ development involves re-thinking development as distinctly generational in its dynamics. For this, we adopt a relational approach to the study of young people in development, which overcomes the limitations inherent to common categorising approaches. Concepts of age and generation are employed to conceptualise young people as social actors and life phases such as childhood and youth in relational terms. Acknowledging the centrality of young people in social reproduction puts them at the heart of development studies and leads the articles comprising this special issue to explore how young people’s agency shapes and is shaped by the changing terms of social reproduction brought about by development

Proposal for post hoc quality control in instrumented motion analysis using markerless motion capture: development and usability study

BACKGROUND: Instrumented assessment of motor symptoms has emerged as a promising extension to the clinical assessment of several movement disorders. The use of mobile and inexpensive technologies such as some markerless motion capture technologies is especially promising for large-scale application but has not transitioned into clinical routine to date. A crucial step on this path is to implement standardized, clinically applicable tools that identify and control for quality concerns. OBJECTIVE: The main goal of this study comprises the development of a systematic quality control (QC) procedure for data collected with markerless motion capture technology and its experimental implementation to identify specific quality concerns and thereby rate the usability of recordings. METHODS: We developed a post hoc QC pipeline that was evaluated using a large set of short motor task recordings of healthy controls (2010 recordings from 162 subjects) and people with multiple sclerosis (2682 recordings from 187 subjects). For each of these recordings, 2 raters independently applied the pipeline. They provided overall usability decisions and identified technical and performance-related quality concerns, which yielded respective proportions of their occurrence as a main result. RESULTS: The approach developed here has proven user-friendly and applicable on a large scale. Raters' decisions on recording usability were concordant in 71.5%-92.3% of cases, depending on the motor task. Furthermore, 39.6%-85.1% of recordings were concordantly rated as being of satisfactory quality whereas in 5.0%-26.3%, both raters agreed to discard the recording. CONCLUSIONS: We present a QC pipeline that seems feasible and useful for instant quality screening in the clinical setting. Results confirm the need of QC despite using standard test setups, testing protocols, and operator training for the employed system and by extension, for other task-based motor assessment technologies. Results of the QC process can be used to clean existing data sets, optimize quality assurance measures, as well as foster the development of automated QC approaches and therefore improve the overall reliability of kinematic data sets

Spectral Indications of Unexpected Contributors to Atmospheric CO\u3csub\u3e2\u3c/sub\u3e Variability?

The frequency spectrum of Northern Hemisphere atmospheric CO2 concentration shows strong periodicities at 6.2, 1.0 and 0.5 years. The 6.2 year cyclicity has been attributed to non-linear interactions between the annual cycle and the atmospheric pole tide. The yearly signal is linked to terrestrial photosynthesis; phase analysis shows that annual CO2 minima occur at a lag of approximately 85 days from insolation maxima. Variations in the nominal yearly period occur during times of anomalous anthropogenic CO2 production. Periodicity at 6 months represents a deviation of the yearly signal from an annual sinusoid. If the yearly signal is largely sinusoidal, a plausible source of the 6 month periodicity could be cyclic phytoplankton productivity driven by natural insolation modes. Together, the three largest spectral peaks account for over 99% of the variation in detrended CO2 data

The Amsterdam Sexual Abuse Case: What Scars did it Leave? Long-Term Course of Psychological Problems for Children Who have been Sexually Abused at a Very Young Age, and their Parents

Longitudinal research of CSA in infancy and early childhood is scarce. The current study examined the long-term course of psychological outcomes (PTSD, dissociation and internalizing and externalizing behavioral problems) in children who were sexually abused in the early childhood. Additionally, we looked into the outcomes for their parents by assessing PTSD symptoms and negative emotional reactions towards the sexual abuse of their child. We examined the outcomes for five consecutive years in a sample of children (n = 45) who were sexually abused at a very young age (0–3) and their parents (n = 42), included in the Amsterdam Sexual Abuse Case-study. We found that outcomes following CSA in early childhood go beyond PTSD symptoms and can manifest in atypical symptoms such as behavioral problems. Parents experienced persistent PTSD in the years following CSA disclosure. CSA in very young children warrants long-term monitoring, as negative outcomes still present 8 years later
