2020 ICM Weekend 1Problem D: Teaming StrategiesAs societies become more interconnected, the set of challenges they face have becomeincreasingly complex. We rely on interdisciplinary teams of people with diverse expertise andvaried perspectives to address many of the most challenging problems. Our conceptualunderstanding of team success has advanced significantly over the past 50+ years allowing forbetter scientific, creative, or physical teams to address these complex issues. Researchers havereported on best strategies for assembling teams, optimal interactions among teammates, andideal leadership styles. Strong teams across all sectors and domains are able to perform complextasks unattainable through either individual efforts or a sequence of additive contributions ofteammates.One of the most informative settings to explore team processes is in competitive team sports.Team sports must conform to strict rules that may include, but are not limited to, the number ofplayers, their roles, allowable contact between players, their location and movement, pointsearned, and consequences of violations. Team success is much more than the sum of the abilitiesof individual players. Rather, it is based on many other factors that involve how well theteammates play together. Such factors may include whether the team has a diversity of skills(one person may be fast, while another is precise), how well the team balances betweenindividual versus collective performance (star players may help leverage the skills of all theirteammates), and the team’s ability to effectively coordinate over time (as one player steals theball from an opponent, another player is poised for offense).In light of your modeling skills, the coach of the Huskies, your home soccer (known in Europeand other places as football) team, has asked your company, Intrepid Champion Modeling(ICM), to help understand the team’s dynamics. In particular, the coach has asked you to explorehow the complex interactions among the players on the field impacts their success. The goal isnot only to examine the interactions that lead directly to a score, but to explore team dynamicsthroughout the game and over the entire season, to help identify specific strategies that canimprove teamwork next season. The coach has asked ICM to quantify and formalize thestructural and dynamical features that have been successful (and unsuccessful) for the team. TheHuskies have provided data[1] detailing information from last season, including all 38 games theyplayed against their 19 opponents (they played each opposing team twice). Overall, the datacovers 23,429 passes between 366 players (30 Huskies players, and 336 players from opposingteams), and 59,271 game events.To respond to the Huskie coach’s requests, your team from ICM should use the provided data toaddress the following: Create a network for the ball passing between players, where each player is a node andeach pass constitutes a link between players. Use your passing network to identifynetwork patterns, such as dyadic and triadic configurations and team formations. Alsoconsider other structural indicators and network properties across the games. You should[1] This data set was processed from a much larger dataset covering nearly 2000 matches from five Europeannational soccer competitions, as well as the 2018 World Cup [1].explore multiple scales such as, but not limited to, micro (pairwise) to macro (all players)when looking at interactions, and time such as short (minute-to-minute) to long (entiregame or entire season). Identify performance indicators that reflect successful teamwork (in addition to points orwins) such as diversity in the types of plays, coordination among players or distributionof contributions. You also may consider other team level processes, such as adaptability,flexibility, tempo, or flow. It may be important to clarify whether strategies areuniversally effective or dependent on opponents’ counter-strategies. Use the performanceindicators and team level processes that you have identified to create a model thatcaptures structural, configurational, and dynamical aspects of teamwork. Use the insights gained from your teamwork model to inform the coach about what kindsof structural strategies have been effective for the Huskies. Advise the coach on whatchanges the network analysis indicates that they should make next season to improveteam success. Your analysis of the Huskies has allowed you to consider group dynamics in a controlledsetting of a team sport. Understanding the complex set of factors that make some groupsperform better than others is critical for how societies develop and innovate. As oursocieties increasingly solve problems involving teams, can you generalize your findingsto say something about how to design more effective teams? What other aspects ofteamwork would need to be captured to develop generalized models of teamperformance?Your submission should consist of: One-page Summary Sheet Table of Contents Your solution of no more than 20 pages, for a maximum of 22 pages with your summaryand table of contents.Note: Reference List and any appendices do not count toward the page limit and should appearafter your completed solution.

Problem E: Drowning in Plastic
Since the 1950s, the manufacturing of plastics has grown exponentially because of its variety of uses, such as food packaging, consumer products, medical devices, and construction. While there are significant benefits, the negative implications associated with increased production of plastics are concerning. Plastic products do not readily break down, are difficult to dispose of, and only about 9% of plastics are recycled[1]. Effects can be seen by the approximately 4-12 million tons of plastic waste that enter the oceans each year[1,2]. Plastic waste has severe environmental consequences and it is predicted that if our current trends continue, the oceans will be filled with more plastic than fish by 2050[2]. The effect on marine life has been studied[3], but the effects on human health are not yet completely understood[4]. The rise of single-use and disposable plastic products results in entire industries dedicated to creating plastic waste. It also suggests that the amount of time the product is useful is significantly shorter than the time it takes to properly mitigate the plastic waste. Consequently, to solve the plastic waste problem, we need to slow down the flow of plastic production and improve how we manage plastic waste.
Your team has been hired by the International Council of Plastic Waste Management (ICM) to address this escalating environmental crisis. You must develop a plan to significantly reduce, if not eliminate, single-use and disposable plastic product waste.
Develop a model to estimate the maximum levels of single-use or disposable plastic product waste that can safely be mitigated without further environmental damage. You may need to consider, among many factors, the source of this waste, the extent of the current waste problem, and the availability of resources to process the waste.
Discuss to what extent plastic waste can be reduced to reach an environmentally safe level. This may involve considering factors impacting the levels of plastic waste to include, but not limited to, sources and uses of single-use or disposable plastics, the availability of alternatives to plastics, the impact on the lives of citizens, or policies of cities, regions, countries, and continents to decrease single-use or disposable plastic and the effectiveness of such policies. These can vary between regions, so considering regional-specific constraints may make some policies more effective than others.
Using your model and discussion, set a target for the minimal achievable level of global waste of single-use or disposable plastic products and discuss the impacts for achieving such levels. You may consider ways in which human life is altered, the environmental impacts, or the effects on the multi-trillion-dollar plastic industry.
While this is a global problem, the causes and effects are not equally distributed across nations or regions. Discuss the equity issues that arise from the global crisis and your intended solutions. How do you suggest ICM address these issues?
Write a two-page memo to the ICM describing a realistic global target minimum achievable level of global single-use or disposable plastic product waste, a timeline to
reach this level, and any circumstances that may accelerate or hinder the achievement of your target and timeline.
Your submission should consist of:

Fishery: The collection of fish of a given species and the area that they inhabit.
Habitat: The type of environment in which an organism or group normally lives or occurs.
Small Fishing Company: A company engaged in commercial fishing with limited or very
limited financial resources to invest in new equipment/vessels.
Territorial Waters (sea): "as defined by the 1982 United Nations Convention on the Law of the
Sea, is a belt of coastal waters extending at most 12 nautical miles (22.2 km; 13.8 mi) from the
baseline (usually the mean low-water mark) of a coastal state. The territorial sea is regarded as
the sovereign territory of the state, although foreign ships (military and civilian) are allowed
innocent passage through it, or transit passage for straits; this sovereignty also extends to the
airspace over and seabed below." [Territorial Waters. (n.d.). In Wikipedia. Retrieved January 28,
