BACKGROUNDS:Alcohol use among adolescents has become a major public health problem in the past decade and has large short- and long-term consequences on their health. The aim of this systematic review was to provide an overview of longitudinal cohort studies that have analyzed the association between the parent-child relationship (PCR) and change in alcohol use during adolescence.METHODS: A search of the literature from 1985 to July 2011 was conducted in Medline, PsycINFO, and EMBASE in order to identify longitudinal, general population studies regarding the influence of the PCR on alcohol use during adolescence. The studies were screened, and the quality of the relevant studies was assessed. A best-evidence synthesis was used to summarize the results.RESULTS: Twenty-eight relevant studies were identified. Five studies found that a negative PCR was associated with higher levels of alcohol use. Another seven papers only found this association for certain subgroups such as boys or girls, or a specific age group. The remaining sixteen studies did not find any association.CONCLUSIONS: We found weak evidence for a prospective association between the PCR and adolescent alcohol use. Further research to the association of the PCR with several types of alcohol use (e.g., initiation or abuse) and to the potential reversed causality of the PCR and alcohol use is required.

Background and aims Osteoarthritis (OA) of the knee or hip is associated with limitations in activities of daily life. There are only a few long-term studies on how knee or hip OA affects the course of physical performance. The aim of this study was to investigate the effects of knee or hip OA on physical performance during a follow-up period of 10 years. Methods Participants in the Longitudinal Aging Study Amsterdam with self-reported hip or knee OA (N = 155) were prospectively followed for 10 years on 4 occasions from the onset of OA and compared to participants without OA (N = 1004). Physical performance was tested with walk, chair stand and balance tests. Scores for each test were summed to a total performance score (range 0–12), higher scores indicating better performance. Generalized estimating equations were used to analyze differences between participants with and without OA, unadjusted as well as adjusted for confounders. Results There was a significant interaction between OA and sex (P = 0.068). Both in men and women, total performance was lower for participants with OA, with greater differences in men. Chair stand and walking performance (P < 0.05), but not balance, were lower in participants with OA. After adjustment for confounders, these associations remained significant in men but not in women. Additional analyses correcting for follow-up duration and attrition showed lower performance scores for men and women with OA. Conclusions OA negatively affected physical performance 3–6 years after it was first reported. Performance in men with OA was more affected than in women.
Longitudinal Business Process Management (BPM) studies are rare. BPM maturity and process performance can be used to quantify an organization's BPM evolution. This research aims to examine the growth of BPM maturity over time and its impact on process performance inside an organization in continuous transformation. Over a seven-year period, BPM maturity and process performance were measured annually at a Dutch university. During this time, the organization has undergone an organizational restructuring with a focus on process management and has temporarily switched completely to digital education propelled by the Covid-19 crisis. Based on a repeated cross-sectional study (N = 921), the results present key BPM maturity features that are critical during disruptive organizational transformations. Furthermore, we found that BPM maturity is positively related to process performance throughout organizational changes during the period of our research

Studenten in het beroepsonderwijs leren op de werkplek om een goede beroepsuitoefenaar te worden. Beoordeling van het werkplekleren gebeurt vaak op de werkplek en door de werkplek. Dit promotieonderzoek wil in kaart brengen hoe werkplekopleiders de student beoordelen.
In societies where physical activity levels are declining, stimulating sports participation in youth is vital. While sports offer numerous benefits, injuries in youth are at an all-time high with potential long-term consequences. Particularly, women football's popularity surge has led to a rise in knee injuries, notably anterior cruciate ligament (ACL) injuries, with severe long-term effects. Urgent societal attention is warranted, supported by media coverage and calls for action by professional players. This project aims to evaluate the potential of novel artificial intelligence-based technology to enhance player monitoring for injury risk, and to integrate these monitoring pathways into regular training practice. Its success may pave the way for broader applications across different sports and injuries. Implementation of results from lab-based research into practice is hindered by the lack of skills and technology needed to perform the required measurements. There is a critical need for non-invasive systems used during regular training practice and allowing longitudinal monitoring. Markerless motion capture technology has recently been developed and has created new potential for field-based data collection in sport settings. This technology eliminates the need for marker/sensor placement on the participant and can be employed on-site, capturing movement patterns during training. Since a common AI algorithm for data processing is used, minimal technical knowledge by the operator is required. The experienced PLAYSAFE consortium will exploit this technology to monitor 300 young female football players over the course of 1 season. The successful implementation of non-invasive monitoring of football players’ movement patterns during regular practice is the primary objective of this project. In addition, the study will generate key insights into risk factors associated with ACL injury. Through this approach, PLAYSAFE aims to reduce the burden of ACL injuries in female football players.

Dit promotieonderzoek wil in kaart brengen hoe werkplekopleiders de student beoordelen.Doel Het doel van dit promotieonderzoek is om het beoordelingsproces van werkplekopleiders in kaart te brengen en te analyseren. Door inzichten over dit proces te ontwikkelen en de huidige praktijk te analyseren willen we sterke en zwakke kanten van dit proces identificeren om zo bij te kunnen dragen aan de ondersteuning van werkplekopleiders. Implementatie Op basis van de resultaten van dit promotieonderzoek kunnen interventies ontwikkeld worden waarmee beoordelaars ondersteund kunnen worden in het beoordelen van het functioneren van studenten in de beroepspraktijk.

Looptijd 01 september 2016 - 01 september 2020 Aanpak Dit promotieonderzoek betreft een samenwerking tussen de OU en het lectoraat Beroepsonderwijs. De promotor vanuit de OU is prof. dr. Elly de Bruijn (ook lector Beroepsonderwijs), en de co-promotor vanuit het lectoraat Beroepsonderwijs is dr. Liesbeth Baartman. Tijdens dit promotieonderzoek nemen we interviews af en doen we een literatuurreview om in beeld te brengen wat er al bekend is in theorie en praktijk. Daarna doen we een longitudinale case study om het beoordelingsproces van werkplekopleiders gedurende de stage in kaart te brengen.
