Crowdsourcing contests have emerged as a popular approach for organisations to leverage collective intelligence and tap into the expertise of a diverse crowd. Knowledge sharing in such contests is paramount in promoting individual or team participation. This study employs negative binomial regression analysis to explore the impact of dynamic knowledge-sharing features - knowledge volume, knowledge expansion, knowledge innovation, and knowledge popularity - on team participation, using data from 211 crowdsourcing contests hosted on Kaggle. The findings offer significant implications for researchers and practitioners regarding effective knowledge management within crowdsourcing platforms. Encouraging knowledge sharing and collaboration and promoting innovative practices can significantly boost the attraction of more participating teams while amplifying the volume of submissions. Additionally, this study underscores the importance of implementing mechanisms to mitigate knowledge overload and ensure diversity of ideas, thereby sustaining engagement and promoting more unique submissions.

Research on children's technology and digital media (TDM) is hampered by a lack of robust approaches for assessing TDM use. This study assessed the feasibility of passively measuring children's TV screens and mobile devices (TDM) in a naturalistic setting. In the three-day feasibility study, FLASH-TV was set up on one to two TVs the child (5-12 year olds) typically used in the home (n=20). Children's mobile device use was assessed with either the Chronicle App or ScreenTime screenshots. Parents completed three TDM diaries. An exit interview with the parent explored their perceptions of the assessments and the child's TDM use report. Complete data were obtained on 86.7% of days for passive assessment of TV viewing and 84.3% of days for mobile device use. Fifteen parents reviewed complete TDM use reports for their child, with most stating the reports appeared correct for TV (80%) and mobile device (80%). Almost two-thirds had no concerns about having the FLASH-TV installed in their home, while some reported issues about feeling observed. Parents described high burden and frustration with the TDM diaries. Data provided preliminary evidence that passive measurement is feasible for assessing children's TV and mobile device use, with reduced burden for parents.

Fathers' perinatal mental health is a major public health issue, yet few interventions have been developed targeting this group. Fathers face many barriers in accessing perinatal mental health support, including stigma around caregiving and mental health, and thus require careful consideration when designing interventions. This study aimed to examine the feasibility, acceptability, and usability of a mobile app-based intervention for paternal perinatal depression, anxiety, and stress. Following a design science approach, five meta design principles and 15 specific principles were created to guide the intervention design, and a prototype app titled Rover was created. The prototype was evaluated by 43 fathers and 10 mental health clinicians. Participants in both groups rated the app highly for its functionality, clinical content, aesthetics, and digital therapeutic alliance. Qualitative feedback indicated that fathers held particularly favourable views regarding the mood tracking, mindfulness, and goal tracking features. Both groups expressed a preference for more support for the personalisation of content, including more dynamic interactions with the chatbot support feature. To our knowledge, this is the first app-based mental health intervention designed specifically for fathers, with study results providing guidance to the field on developing digital health initiatives for this population.
