Justice Reinvestment in Bourke

Model Explanation:

One part of this model is displaying the typical lifestyle of many adults and youth in the town Bourke, North West of New South Wales. This lifestyle involves committing crime, getting arrested for the crime by police (or getting away with it) and spending time in jail (for adults) or juvenile detention (for the youth) or simply getting discharged.

Additionally to this traditional lifestyle being modelled, an alternative option called community groups has also been incorporated into the model. The model is showing that members of Bourke have the option to join a community group which the government hopes will improve their lifestyle when they are immersed once again into society, thus reducing the rate of crime.

The Stocks Involved:

Adult- The adults living in Bourke
Youth- The adolescents living in Bourke
Petty Crime- The standard crime committed by the youth of Bourke. This can include stealing cars and breaking into property.
Crime- The common crime circulating among the adults of Bourke. This includes domestic violence often as a result of heavy drinking.
Apprehended- Youth getting captured by the police
Arrested- Adults getting caught by the police
Juvenile Detention- Alienation of youth by police
Jail- Adults locked up by the police
Community Group- Groups formed for the people of Bourke to join. Includes development activities, sporting clubs and trade-skill learning classes.
Positive Lifestyle- Adults and youth who have improved themselves as a result of joining these community groups (the goal of community engagement program expenditure).

The Variables Involved and How to Adjust Them:

1. Policing: The number of police in the town of Bourke. The level and amount of punishment is dependent on the quantity of police present. 

Minimum amount is one as there should be at least one police existent.

2. Community Engagement Expenditure: The total amount of money spent into community groups to develop individuals. 

The purpose of the government is to spend money on community engagement activities so the minimum is at least one percent of the money they have available to spend and the maximum is 100 percent of the money they can afford to spend.

--> Both variables have a slider that goes up and down by one step. You can adjust both variables at the same time but take into account both variables have their own minimum and maximum.

Underlying Assumptions:

-Approximately 3000 people in Bourke

-Coefficients and initial values are arbitrarily chosen. These would be modified with real-life data.

-The only external influences on this model are police and community investment.

Suggested Settings for Interesting Results:

1. First move the policing and community expenditure sliders to their maximum. Hit the simulate button and look at the first time-series graph titled 'Youth Lifestyle'. Notice the delays between increase of each stock and the ordering: As Youth decreases, Petty Crime will increase. Then youth Apprehended will begin to increase followed by those going to Juvenile Detention. Youth will then start to increase again and the trend continues over the 3-year period displayed. Notice how the same pattern occurs for the time-series graph labelled 'Adult Lifestyle'.

2. Move the policing slider to 1 and the community expenditure slider to 100. Hit simulate. Notice in the 'Youth Lifestyle' graph how even with community expenditure at its maximum, over time, Petty Crime will still increase because there are hardly any police and hence hardly any youth getting caught so as a result the youth in Bourke keep to their regular immoral lifestyle. If you view the 'Adult Lifestyle' graph you will see the same pattern. (Note this point is a main reason for the conclusion drawn below).

3. Move the community engagement and policing slider to their minimum 1. Hit simulate. View the third display titled 'Community Engagement Program'. You will notice how Youth and Adult decrease and Crime and Petty Crime increase. Also, since community engagement is at its minimum too (not just policing) the amount of people in Community Groups decreases significantly and as a result the number of individuals creating a Positive Lifestyle for themselves decreases too.

4. Move the Community Engagement Expenditure slider to 1 and the Policing slider to 50 and look particularly at the last display labelled 'Adults and Youth: Membership and Crime Rates'. You will notice instantly how Community Group and Positive Lifestyle always have a lower number of individuals compared to the general Youth and Adult stocks as well as the Crime and Petty Crime stocks. This gives indication that a higher amount of investment should be put into the community engagement programs for better results. 

Conclusions:

A combination of policing and community engagement expenditure is the best solution for the people of Bourke as the policing will gradually reduce the amount of crime and the community development programs will help create a positive lifestyle for each individual that joins. Overall it is not efficient to just invest in community development programs. For the most effective outcome, an increase in policing is needed as well as investments in community engagement activities.

Note: You do not need to dive into any formulae. But feel free to move the sliders and hit that simulate button to view how the number of people in each stock changes based on the level of policing and community engagement expenditure!

This is a model designed to ​demonstrate the effects of policing and community development/engagement programs on the youth of Bourke, by simulation the state of the community at different levels of both policing and the programs.

Variables:

There are 6 stocks and 2 variables.

The stocks are arranged to represent the different options for the youth in Bourke. Their options are; don't commit a crime; do commit a crime and risk being convicted; or take part in various community development/engagement programs available.

The 2 variables are Police and Community Development Fund, both are adjustable via the sliders to the right hand side, and represent 2 of the major forces acting on the youth's choices.

Suggestion:

The aim of the model is to emphasize the overall importance of community development/engagement programs for youths in Bourke.

To see the impact these programs can have adjust the sliders:
     . 100 Police and 0.1 Community Funds - This will show the negative effect of severe law enforcement as a larger number of youths end up in juvenile detention.

     . 100 Police and 100 Community Development Funds - This will show the improvement in the community compared to the last suggestion as more youths are in the programs helping them rather than juvenile detention.

     . 10 Police and 200 Community Development Funds - This will show that almost all youths end up in the programs helping them and very few in juvenile detention. This further illustrated the point made before about the importance of these programs in Bourke.

BACKGROUND

The remote north-western town of Bourke currently faces high incidences of petty crime among the town’s youth.

Part of the problem stems from the alienation and lack of recreational activities the youth face from being a small isolated town, which has meant that the threat of being sent to Juvenile Detention isn't acting as much of a deterrent.

This complex systems model aims to show how investing in different variables can change this cycle.

While there are numerous underlying factors that perpetrate the cycle of Bourke youth being locked up, this model has a main focus on Youth Alienation

 

MODEL EXPLAINED

Simulation of this model shows results over 3 years with Time Units in steps of 1 Month.

Total Youth Population of Bourke stays static at 1200 over the 3 years.

This model only looks as Individuals committing petty crimes as opposed to groups of Youth getting together to commit petty crime (we are not considering peer pressure as a factor of petty crime rates).

 

At Time Point 0, all 1200 of Bourke Youth are in the Stock Home, and all other stocks are empty. Youth flow out from Home to other stocks from Time Point 1. 

 

STOCKS

- Home = Number of Bourke youth at 'Home'.

i.e. not committing crimes but not taking part in Community Engagement Programs

- Community Engagement Programs = Number of Bourke Youth taking part in Bourke's Community Engagement Programs.

Community Engagement Programs consist of multiple things such as Sporting Clubs and Indigenous Community Events

- Petty Crime = Number of Bourke Youth committing Petty Crimes.

- Juvenile Detention = Number of Bourke Youth in Juvenile Detention.

- Discharged = Number of Bourke Youth in state of being Discharged from Juvenile Detention.

- Upstanding Citizen = Number of Bourke Youth that are Upstanding members of the Bourke Community.

 

ADJUSTABLE VARIABLES

- Community Development Resource $ = Amount of Money being Invested into Community Development

i.e. 15000 = $15000 into Community Development Fund

- Police Officers = Number of Police Officer in Bourke

i.e. 15 = 15 Active Police Officers

- Police Initiative Rate = % Amount of Investment Police put into active Policing. (AKA Police efficiency)

i.e. 0.1 = 10% effectiveness (police appear to be corrupt)

 

 

UN-ADJUSTABLE VARIABLES

- Positive Influences at Home = % of Bourke Youth that have strong enough Positive Social Influences at Home to not want to commit crimes.

Positive Influences at Home is a constant 0.5% percent.

Assumptions:

0.5% of the  juvenile population of Bourke already have strong positive social influences at home that have them highly unlikely to want to commit petty crimes.

Positive Influences at Home is a fixed variable as the factors affecting this % are too complex for any reliable intervention.

- Boredom & Recklessness = % of Bourke Youth that are Bored and Reckless enough to want to commit crimes.

Boredom and Recklessness is a constant 5%.

Assumptions:

5% of the juvenile population of Bourke is always going to be bored/reckless enough to want to commit petty crimes.

 

DYNAMIC VARIABLES

- Youth Alienation = % of Bourke Youth that feel Alienated/have no sense of community.

Youth Alienation is a dynamic percentage.

Assumptions:

Community Development Program and Upstanding Citizen  decreases Alienation. Everyone who partakes in the community engagement programs is unalienated. All Upstanding Citizens are unalienated.

Before taking into account those people that are in the Community Development Program and Upstanding Citizen stocks we assume that 90% of the Bourke youth population to be Alienated.

i.e. when Upstanding Citizen and Community Engagement Programs are both empty, Youth Alienation = 90%

 

 

FLOWS

- Community Involvement (Dynamic Rate)

For every $1000 invested into Community Development Resource $, the rate of flow from Home to Community Engagement Programs increases by 2%.

The rate of flow from Home to Community Engagement Programs also is dependent on the attendance of youth to Community Program itself (word of mouth advertising). For every 50 children coming to Community Engagement Programs we have a percentage increase in Community Involvement rate.

- Lack of Interest (Constant Rate)

Flow rate from Community Engagement Programs to Petty Crime is simply the % rate of the Boredom & Recklessness variable.

- Temptation (Dynamic Rate)

Flow rate from Home to Petty Crime is dependent on the 4 Variables of Youth Alienation, Boredom & Recklessness, Police Officers and Police Initiative Rate.

Youth Alienation and Boredom & Recklessness increase Temptation Flow.

Police Officers and Police Initiative Rate decrease Temptation Flow.

Temptation flow is also reduced by the 0.5% Positive Influences at Home

- Conviction (Dynamic Rate)

Flow rate from Petty Crime to Juvenile Detention is dependent on the 2 variables Police Officers and Police Initiative Rate.

Police Officers and Police Initiative Rate increase Conviction Flow.

- Not Caught (Dynamic Rate)

Flow rate from Petty Crime back to Home is dependent on the Conviction Flow Rate.

Increased Conviction Flow is directly proportional to a Decrease in the Not Caught Flow.

- Served Sentence (Constant Rate)

Flow rate from Juvenile Detention to Discharged is just a delay of Juvenile Detention population by 4 months.

Assumption: The average Petty Crime Conviction results in a 4 month Juvenile Detention Centre Sentence. 

- Further Negative Influence (Constant Rate)

Flow rate from Discharged to Petty Crime is a constant 25%.

Assumption: There is a constant 25% of Youth that having been convicted once are actually more likely to commit petty crimes (for various reasons) and are no longer wary of Police.

- Active Rehabilitation (Dynamic Rate)

Flow rate from Discharged to Community Engagement Programs is dependent on the Community Development Resource $ variable.

Community Development Resource $ encourage Discharged Youth to want to change their ways.

For every $2000 invested into Community Development Resource $'s Active Rehabilitation Rate increase a percent.

- Unchanged (Dynamic Rate)

Flow rate from Discharge to Home is dependent on Active Rehabilitation Rate and Further Negative Influence Rate.

Increased Active Rehabilitation Flow is directly proportional to decrease in the Unchanged Flow.

 Unchanged Flow is also reduced by the Further Negative Influences Flow of 25%.

- Inspired (Constant Rate)

Flow rate from Home to Upstanding Citizen is simply the percentage rate of the Positive Influences at Home variable.

- Self Improvement (Constant Rate)

Flow rate from Community Engagement Programs to Upstanding Citizen is a constant 5%.

Assumption: There is a constant 5% of Youth that have been partaking in the Community Engagement Programs who have been so well received that they are conscientious Upstanding Members of Bourke society.

- Hits Hard Times (Constant Rate)

Flow Rate from Upstanding Citizen to Home is a constant 1%

Assumption: Upstanding Citizens are not infallible and there are some circumstances which lead to Upstanding Citizens suddenly being susceptible to the alienation, boredom and recklessness.

 

EFFECT OF CHANGING VARIABLES

Base Settings:

Police Officers = 10

Community Development Resource $ = 5,000

Police Initiative Rate = 1

 

⮝ Increasing Community Development Resource $

- Increases Community Involvement Flow, therefore increasing Community Engagement Programs, which in turn decreases Youth Alienation. Decrease in Youth Alienation, decreases Temptation Flow.

- Increases Active Rehabilitation Flow, therefore increasing Community Engagement Programs.

- Increases Upstanding Citizen due to the increase in Community Engagement Programs.

⮟ Decreasing Community Development Resource $

- Decreases Community Involvement Flow, therefore decreasing Community Engagement Programs, which in turn increases Youth Alienation. Increase in Youth Alienation, increases Temptation Flow.

- Decreases Active Rehabilitation Flow, therefore decreasing Community Engagement Programs .

- Decreases Upstanding Citizen due to the decrease in Community Engagement Programs.

 

 

⮝ Increasing Police Officers

- Decreases Temptation Flow therefore decreasing Petty Crime.

- Increases Conviction Flow therefore increasing Juvenile Detention.

⮟ Decreasing Police Officers

- Increases Temptation Flow therefore increasing Petty Crime.

- Decreases Conviction Flow therefore decreasing Juvenile Detention.

 

 

⮝ Increasing Police Initiative

 - Decreases Temptation Flow therefore decreasing Petty Crime.

- Increases Conviction Flow therefore increasing Juvenile Detention.

⮟ Decreasing Police Initiative

- Increases Temptation Flow therefore increasing Petty Crime.

- Decreases Conviction Flow therefore decreasing Juvenile Detention.

 

 

INTERESTING POINTS

  • Try setting Community Development Resource $ to 0 , Police Officers to 30 and Police Initiative Rate to 1.

Notice how Youth just constantly circulate between Home, Petty Crime, Juvenile Detention and Discharged with the amount of children in Community Engagement and Upstanding Citizens stocks seem Negligible

  • Try setting Community Development Resource $ to 30,000 ,  Police Officers to 1 and Police Initiative Rate to 1.

Notice that while we have a lot of Petty Crime going unpunished we have a significant proportion of the Bourke Youth in Community Engagement Programs and becoming Upstanding Citizens

  • Try setting Community Development Resource $ to 0 , Police Officers to 30 and Police Initiative Rate to 0.1.

Notice that the situation in Bourke looks very bleak, we have the majority of the youth population committing crimes and even though there's never really any improvement in the situation.

Justice Reinvestment in Bourke

Model Explanation:

One part of this model is displaying the typical lifestyle of many adults and youth in the town Bourke, North West of New South Wales. This lifestyle involves committing crime, getting arrested for the crime by police (or getting away with it) and spending time in jail (for adults) or juvenile detention (for the youth) or simply getting discharged.

Additionally to this traditional lifestyle being modelled, an alternative option called community groups has also been incorporated into the model. The model is showing that members of Bourke have the option to join a community group which the government hopes will improve their lifestyle when they are immersed once again into society, thus reducing the rate of crime.

The Stocks Involved:

Adult- The adults living in Bourke
Youth- The adolescents living in Bourke
Petty Crime- The standard crime committed by the youth of Bourke. This can include stealing cars and breaking into property.
Crime- The common crime circulating among the adults of Bourke. This includes domestic violence often as a result of heavy drinking.
Apprehended- Youth getting captured by the police
Arrested- Adults getting caught by the police
Juvenile Detention- Alienation of youth by police
Jail- Adults locked up by the police
Community Group- Groups formed for the people of Bourke to join. Includes development activities, sporting clubs and trade-skill learning classes.
Positive Lifestyle- Adults and youth who have improved themselves as a result of joining these community groups (the goal of community engagement program expenditure).

The Variables Involved and How to Adjust Them:

1. Policing: The number of police in the town of Bourke. The level and amount of punishment is dependent on the quantity of police present. 

Minimum amount is one as there should be at least one police existent.

2. Community Engagement Expenditure: The total amount of money spent into community groups to develop individuals. 

The purpose of the government is to spend money on community engagement activities so the minimum is at least one percent of the money they have available to spend and the maximum is 100 percent of the money they can afford to spend.

--> Both variables have a slider that goes up and down by one step. You can adjust both variables at the same time but take into account both variables have their own minimum and maximum.

Underlying Assumptions:

-Approximately 3000 people in Bourke

-Coefficients and initial values are arbitrarily chosen. These would be modified with real-life data.

-The only external influences on this model are police and community investment.

Suggested Settings for Interesting Results:

1. First move the policing and community expenditure sliders to their maximum. Hit the simulate button and look at the first time-series graph titled 'Youth Lifestyle'. Notice the delays between increase of each stock and the ordering: As Youth decreases, Petty Crime will increase. Then youth Apprehended will begin to increase followed by those going to Juvenile Detention. Youth will then start to increase again and the trend continues over the 3-year period displayed. Notice how the same pattern occurs for the time-series graph labelled 'Adult Lifestyle'.

2. Move the policing slider to 1 and the community expenditure slider to 100. Hit simulate. Notice in the 'Youth Lifestyle' graph how even with community expenditure at its maximum, over time, Petty Crime will still increase because there are hardly any police and hence hardly any youth getting caught so as a result the youth in Bourke keep to their regular immoral lifestyle. If you view the 'Adult Lifestyle' graph you will see the same pattern. (Note this point is a main reason for the conclusion drawn below).

3. Move the community engagement and policing slider to their minimum 1. Hit simulate. View the third display titled 'Community Engagement Program'. You will notice how Youth and Adult decrease and Crime and Petty Crime increase. Also, since community engagement is at its minimum too (not just policing) the amount of people in Community Groups decreases significantly and as a result the number of individuals creating a Positive Lifestyle for themselves decreases too.

4. Move the Community Engagement Expenditure slider to 1 and the Policing slider to 50 and look particularly at the last display labelled 'Adults and Youth: Membership and Crime Rates'. You will notice instantly how Community Group and Positive Lifestyle always have a lower number of individuals compared to the general Youth and Adult stocks as well as the Crime and Petty Crime stocks. This gives indication that a higher amount of investment should be put into the community engagement programs for better results. 

Conclusions:

A combination of policing and community engagement expenditure is the best solution for the people of Bourke as the policing will gradually reduce the amount of crime and the community development programs will help create a positive lifestyle for each individual that joins. Overall it is not efficient to just invest in community development programs. For the most effective outcome, an increase in policing is needed as well as investments in community engagement activities.

Note: You do not need to dive into any formulae. But feel free to move the sliders and hit that simulate button to view how the number of people in each stock changes based on the level of policing and community engagement expenditure!
