Both public and private organizations are opening their data for use by others. Although information could be requested for in the past, governments have changed their strategy toward actively publishing open data in formats that are readily and easily accessible.

Multiple perspectives are needed to make use of and stimulate new practices based on open data (Zuiderwijk et al. 2014). New applications and innovations can be based solely on open data, but often open data are enriched with data from other sources. As data can be generated and provided in huge amounts, specific needs for processing, curation, linking, visualization, and maintenance appear. The latter is often denoted with big data in which the value is generated by combining different datasets (Janssen et al. 2014). Current advances in processing power and memory allow for the processing of a huge amount of data.

BOLD allows for analyzing policies and the use of these data in models to better predict the effect of new policies. In policy implementation and execution, many actors are involved and there are a huge number of factors influencing the outcomes; this complicates the prediction of the policy outcomes. Simulation models are capable of capturing the interdependencies between the many factors and can include stochastic elements to deal with the variations and uncertainties. Simulation is often used in policy-making as an instrument to gain insight into the impact of possible policies which often result in new ideas for policies.

Simulation allows decision-makers to understand the essence of a policy, to identify opportunities for change, and to evaluate the effect of proposed changes in key performance indicators (Banks 1998; Law and Kelton 1991). Simulation heavily depends on data and as such can benefit from big and open data. Simulation models should capture the essential aspects of reality. They do not rely heavily on mathematical abstraction and are therefore suitable for modeling complex systems (Pidd 1992).

Moreover, the development of a model can raise discussions about what to include and what factors are of influence, thus contributing to a better understanding of the situation at hand. Experimentation using models allows one to investigate different settings and the influence of different scenarios over time on the policy outcomes. The effects of policies are hard to predict, and dealing with uncertainty is a key aspect in policy modeling. Statistical representation of real-world uncertainties is an integral part of simulation models (Law and Kelton 1991).

The dynamics associated with many factors affecting policy-making, the complexity associated with the interdependencies between individual parts, and the stochastic elements associated with randomness and unpredictable behavior of transactions complicate the simulations. Computer simulations for examining, explaining, and predicting social processes and relationships, as well as measuring the possible impact of policies, have become an important part of policy-making.

Traditional models are not able to address all aspects of complex policy interactions, which indicates the need for the development of hybrid simulation models consisting of a combinatory set of models built on different modeling theories (Koliba and Zia 2012). In policy-making, it can be that multiple models are developed, but it is also possible to combine various types of simulation in a single model.

For this purpose, agent-based modeling and simulation approaches can be used, as these allow for combining different types of models in a single simulation. Efforts to design public policies are confronted with considerable complexity, involving a large number of potentially relevant factors, a vast amount of data, a high degree of uncertainty, and rapidly changing circumstances.

Utilizing computational methods and various types of simulation and modeling methods is often key to solving these kinds of problems (Koliba and Zia 2012). The open data and social media movements are making large quantities of new data available. Concurrently, enhancements in computational power have expanded the repertoire of instruments and tools available for studying dynamic systems and their interdependencies.

In addition, sophisticated techniques for data gathering, visualization, and analysis have expanded our ability to understand, display, and disseminate complex, temporal, and spatial information to diverse audiences. These problems can only be addressed from a complexity science perspective and with multiple views and contributions from different disciplines. Insights and methods of complexity science should be applied to assist policy-makers as they tackle societal problems in policy areas such as environmental protection, economics, energy, security, or public safety and health.

This demands user involvement, supported by visualization techniques, and can be actively engaged by employing (serious) games. These methods can illustrate hypothetically what will happen when certain policies are implemented. Research by Pearson et al. (2003) investigated the treatment effects of a drug on cognitive functioning in children with mental retardation and ADHD.

This study involved children who were administered various dosages of a drug, methylphenidate (MPH), and completed a Delay of Gratification (DOG) task. Each participant performed the task after each dosage as part of a repeated-measures design. This task, adapted from the preschool delay task of the Gordon Diagnostic System, measures the ability to suppress or delay impulsive behavioral responses.

Children were informed that a star would appear on the computer screen if they waited “long enough” to press a response key. If a child responded sooner than four seconds after their previous response, they did not earn a star, and the counter restarted. This method differentiates children with and without ADHD and is sensitive to MPH treatment in these children (Hall & Kataria, 1992).

In addressing whether higher dosage leads to higher cognitive performance (measured by the number of correct responses to the DOG task), it is pivotal to examine the variable descriptions including number of correct responses after taking a placebo, and various dosages of the drug.

The study of cognitive performance in relation to dosages of methylphenidate (MPH) among children diagnosed with mental retardation and Attention-Deficit/Hyperactivity Disorder (ADHD) provides significant insights into the relationship between drug dosage and cognitive function. The pioneering research conducted by Pearson et al. (2003) aims to establish this relationship by employing a repeated-measures design that enables the assessment of cognitive performance across different dosages.

The Delay of Gratification (DOG) task serves as a crucial measurement tool in this study, effectively distinguishing between children with and without ADHD. It assesses the ability of children to delay impulsive responses, providing a quantifiable performance metric amenable to analysis through an ANOVA framework. The methodology involved administering the drug at varying dosages—placebo (d0), 0.15 mg/kg (d15), 0.30 mg/kg (d30), and 0.60 mg/kg (d60)—which allows for the exploration of the hypothesis that increased dosages would correlate with improved cognitive performance.

The expected outcomes of the study may align with the broader implications of stimulant medication in managing ADHD symptoms, particularly in relation to cognitive tasks requiring impulse control and delayed responses. Prior research has indicated that stimulant medications like MPH can enhance cognitive performance and facilitate better behavioral outcomes in children with ADHD (Hall & Kataria, 1992; Mayes et al., 2002). However, it is critical to consider the underlying biological and psychological mechanisms that could mediate these effects.

In this context, the role of open data and big data analytics becomes increasingly significant, as new policies increasingly rely on data-driven insights for decision-making. The contemporary capabilities offered by computational methods transform the landscape of policy analysis and implementation, allowing for nuanced modeling and simulations of complex interactions that can arise from multifactorial influences. Simulation techniques provide an essential means to explore the myriad outcomes associated with differing policy interventions and drug treatments.

As the study posits that higher dosages would likely yield better cognitive results on the DOG task, the challenge remains to accurately quantify and assess those outcomes while also managing the inherent uncertainties associated with varied individual responses to treatment. The analytical model integrates statistical representations of these outcomes, relying heavily on ANOVA analysis to gauge the impacts of dosage variations effectively.

The findings of this research carry important implications not only for therapeutic interventions but also for policy innovations surrounding ADHD management and broader mental health strategies. The intersection of healthcare and public policy requires an ongoing dialogue facilitated by data transparency and increased collaboration across sectors, enabling a more comprehensive approach to understanding and treating cognitive and behavioral health issues.

Effective policymaking, increasingly supported by open data initiatives, aids in elucidating the multifaceted nature of ADHD and similar disorders. By leveraging programming and analysis tools enabled by BOLD frameworks, policy-makers can make informed decisions that are reflective of the diverse needs of the affected population, ultimately fostering an environment conducive to improved health outcomes.

In conclusion, the research illustrates a critical relationship between drug dosages and cognitive functioning within a specific demographic, shedding light on significant mental health management strategies. It underscores the importance of ongoing data dissemination and collaboration in driving policy innovation that addresses the needs of children facing cognitive challenges due to ADHD and mental retardation.
