Bourke Youth Crime Model

This simple model is designed to simulate crime amongst youth in the country town of Bourke, Australia.

Bourke has a youth population (under 24 years of age) of 998 (ABS, 2015). These 998 persons begin arbitrarily split between the general population [Bourke Youth], youth in the football club [Football Club], youth engaged in criminal activity [Criminals] and incarcerated youth [Prisoners]

The rates of transfer between these blocks are determined by several logical mechanisms which are explained below. All calculations are rounded for the obvious reason that populations are necessarily integer values. To facilitate investigation into the interaction between variables, only Police and Funding are adjustable. Any other inputs would unnecessarily complicate the model, and degrade its usability and usefulness.

Observations:

Police and Funding have an interaction that determines the outcome for criminals in the simulation. At a funding multiplier of 1 (standard) and with minimum police, Criminals outnumber youths by the end of the simulation. As the funding is decreased, this threshold increases until a funding multiplier of 0.2, where even the maximum number of police cannot control the criminal population.

Perhaps most interestingly, the equilibrium prisoner population depends on the sports club funding multiplier, not the number of police.

An interesting comparison can be found between setting the funding multiplier to 1.5 and police to 100, and setting funding to 0.3 with police at 225. This comparison is an ideal use for this model, as it reflects the benefits from community engagement seen in the case study.

Rates:

Commit Crime: The crime rate in Bourke is modelled to be dependent on several factors, principally the number of police in Bourke (a greater police presence will reduce crime). It is also assumed that a greater general youth population will increase the rate of crime, and that participation in the football club (or interaction with other engaged community members) will discourage crime. For these reasons, the rate of criminalisation is modelled with the equation:

Round([Bourke Youth]^2/([Football Club]*[Police]+1))

Arrested: The arrest rate is determined by a factor of the number of police available to charge and arrest suspects, as well as the number of criminals eligible for arrest. A natural logarithm is taken for police, as police departments should see diminishing returns in adding more officers. A logarithm is also taken of criminals to allow it to factor into the rate without swamping the effect of police. Thus, the rate is calculated with:

Round(ln([Police]+1)*5*log([Criminals]+1))

Released: The release rate is a straightforward calculation; it is set to increase with the square of the number of prisoners to keep the maximum number of inmates low. This is because Bourke is a small town with a small gaol and it would have to prematurely release inmates as the inmate population overflowed. Thus it is calculated with:

Round(0.001*[Prisoners]^2)

Recruited: The Football recruitment rate is assumed to be dependent on the population available for recruitment, and the funding received for the football club. A better funded club would recruit youths in greater numbers. Consequently, the recruitment rate is calculated with:

Round(ln([Bourke Youth]+1)*[Funding Modifier]+1)

Dropout Rate: The dropout rate from the football club is assumed to be dependent on the number of players (a proportion should quit every season) and the funding of the club (a well funded club should retain more players. Thus it is calculated with:

Round(1+ln([Football Club]*10/([Funding Modifier]+5)))

Self Adjust: A small leak flow to represent those criminals that cease their criminal activity and return to the general population.

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.

About the Model

This model is designed to simulate the youth population in Bourke, specifically focusing on the number of criminals and incarcerated dependent on a few key variables.

Within the model, a young person living in Bourke can be classified as being in any of five states:

Young Community Member: The portion of the youth population that is not committing crime and will not commit crime in the future. Essentially the well behaved youths. A percentage of these youths will become alienated and at risk.

Alienated and At Risk Youths: The youths of Bourke that are on the path of becoming criminals, this could be caused by disruptive home lives, alcohol and drug problems, and peer pressure, among other things.

Criminal: The youths of Bourke who are committing crimes. Of these criminals a percentage will be caught and convicted and become imprisoned, while the remainder will either go back to being at risk and commit more crimes, or change their behaviour and go back to being a behaving community member.

Imprisoned: The youths of Bourke who are currently serving time in a juvenile detention centre. Half of the imprisoned are released every period at a delay of 6 months.

Released: Those youths that have been released from a detention centre. All released youths either rehabilitate and go back to being a community member or are likely to re-offend and become an alienated and at risk youth.

The variables used in the model are:

Police- This determines the police expenditure in Bourke, which relates to the number of police officers, the investment in surveillance methods and investment in criminal investigations. The level of expenditure effects how many youths are becoming criminals and how many are being caught. An increase in police expenditure causes an increase in imprisoned youths and a decrease in criminals.

Community Engagement Programs- The level of investment in community engagement programs that are targeted to keep youths in Bourke from becoming criminals. The programs include sporting facilities and clubs, educational seminars, mentoring programs and driving lessons. Increasing the expenditure in community engagement programs causes more young community members and less criminals and at risk youths.

Community Service Programs- The level of investment in community service programs that are provided for youths released from juvenile detention to help them rehabilitate and reintegrate back into the community. An increase in community service expenditure leads to more released prisoners going back into the community, rather than continuing to be at risk. Since community service programs are giving back to the community, the model also shows that an increase in expenditure causes a decrease in the amount of at risk youths.

All three of these variables are adjustable. The number of variables has been kept at three in order to ensure the simulation runs smoothly at all times without complicated outputs, limitations have also been set on how the variables can be adjusted as the simulation does not act the same out of these boundaries.

Key Assumptions:

The model does not account for the youths’ memory or learning.

There is no differentiation in the type of criminals and the sentences they serve. Realistically, not all crimes would justify juvenile detention and some crimes would actually have a longer than six-month sentence.

The constants within in the calculations of the model have been chosen arbitrarily and should be adjusted based on actual Bourke population data if this model were to be a realistic representation of Bourke’s population.

The model assumes that there are no other factors affecting youth crime and imprisonment in Bourke.

There are 1500 youths in Bourke. At the beginning of the simulation:

Young Community Member = 700

Alienated and At Risk Youth = 300

Criminal = 300

Imprisoned = 200

Noteworthy observations:

Raising Police expenditure has a very minimal effect on the number of at risk youths. This can be clearly seen by raising Police expenditure to the maximum of twenty and leaving the other two variables at a minimum. The number of Alienated and at Risk Youths is significantly higher than the other states.

Leaving Police expenditure at the minimum of one and increasing community development programs and community service programs to their maximum values shows that, in this model, crime can be decreased to nearly zero through community initiatives alone.

Leaving all the variables at the minimum position results in a relatively large amount of crime, a very low amount of imprisoned youth, and a very large proportion of the population alienated and at risk.

An ideal and more realistic simulation can be found by using the settings: Police = 12, Community Engagement Programs = 14, Community Service Programs = 10. This results in a large proportion of the population being young community members and relatively low amounts of criminals and imprisoned.

This model displays the effects of youth crime and the influence of community expenditure, social support, and policing in the town of Bourke, NSW.

The traditional lifestyle for youth in this town involves either a chosen path of committing crimes, or, that of community activity and various forms of education.

The model has been designed to mimic a system where community expenditure and support services are adopted in order to inject a positive lifestyle for the youth population. The phenomena studied in this simulation is the balance between policing, community support and social influence versus not using them.

Assumptions
-1000 Youth Population

-Youth are either influenced by criminal activity or by productive educational activities.

- Adoption rate of community activities is influenced by personality, relating to current personal skill level of youth and willingness.

-If youth you do not become involved in community activity or some form of Education, then they turn to the path of crime.

-Punishment facility time is up to 12 months with a 2 year probation period

-Community expenditure and support only begins in the probation period, unless “Juvenile Support” slider is used.

-For the purpose of this study on youth crime and support before a crime is committed, we do not include a possibility of relapse in the rehabilitation phase.

STOCKS

Youth
Crime – all offences committed by those under 18
Punishment Facility – juvenile detention
Probation – release from punishment
Education system – various programs

VARIABLES

Policing Units – Policing Bourke's criminal activity, and convicting after a crime has been committed.

Juvenile Support Units – The variable change in crime IF the community funds Support Units for youth before a crime is committed.

Social Support Units – The number of social support units available for released offenders during rehabilitation phase.

Community expenditure – the amount of time and money being spent on social services and policing.

Birth rate, crime rate, dicharge rate, recidivism & conviction rate

INTERESTING RESULTS

Slide any of the 3 variables to the extreme.

This model shows that adoption rate of a positive lifestyle is directly influenced by social influences.

1/ Juvenile Support Unit impact

Press Simulate.

Slide Juvenile Support Units to the extreme. Simulate again.

Juxtaposition of Juvenile Support impact on Behavior Graph shows that Crime and Reoffend rates drop significantly. More people turn to law-abiding positive activity.

This will again all change with the manipulation of the Social Support unit slider…..

2/ Social Support Unit impact

Social Support Units only influence those released from the Punishment facility. The more social services on hand to support rehabilitation phase the less chance of committing crime for the second time, with Reoffend rates dropping significantly when the Social Support Units Slider is adjusted to the extreme.

Rehabilitation rates only increase marginally, in spite of more social support feeding into that phase.

The greatest impact is shown on Law-Abiding and Crime. How could this be? A logical conclusion is that there is a finite number of youth in the community and those who have received positive social support during a learning phase of rehabilitation, then go on to influence their friends, their family, and have a positive influence on those around them.

3/ Police Unit Impact

Slide Policing Units to the extremes. Simulate. Policing Units Graph shows there is a significant decrease in Reoffend rates, and a higher rate of Conviction.

Curiously, rehabilitation rates drop and crime rates go up. How could this happen? A logical conclusion is that conviction and punishment is not a crime deterrent. It needs the added influence of social support services for there to be a positive impact on decreasing criminal instincts and activity on the whole.

Conclusions

Social support and home visits need to happen in the flow between Youth Population and Crime - “Juvenile Support Units”.

Investment in youth via these juvenile social support officers before they commit an offence, limits the amount of criminal activity over time. So, crime effectively decreases with the direct influence of social services at a young age.

Equally, with more police presence in the community, for those tempted to re-offend, they have a deterrent.

The most efficient management of the community issues faced in Bourke however lies with a combination of both Policing and Social Support services at all levels within the community.

THE MODEL

Underlying assumptions:

Police Force has a negative relationship with committed crime (criminals) and has a positive relationship with Juvenile Detention.
Community Investment has a negative relationship with committed crime.
Family – Police relations is negatively related to domestic violence rate, which has positive relationship with committed crime.
Only the youth are law-breaking citizens (as this model mainly focuses on this population).
Coefficients are chosen arbitrarily. We may need more real data and research to determine the appropriate ones.

Constants:

It took six months for Community Investment (which includes soccer team, trade-skills class and driving class) and Family – Police Relations to work.
Juvenile detention length is also 6 months.

Things to note:

Youth in Bourke committed crime mainly because of the influence from high domestic violence rate, low police force rate (police investment), as well as low community investment rate. The figure was used to calculate the number of youth committing crime is the average of these three rates.
Those violent families were detected by the Police Force, but then supervised by the responsible team, therefore reduce bad effects on the youths who have been suffering from that and finally reduce the likelihood of committing crimes.
Community Investment in forming soccer team, trade-skills classes and driving classes moved a portion of returning criminals (the ones not got caught) to community engagement, therefore reduce the chances of committing crimes of these individuals.
Maximizing the Police Force rate is probably the best way to reduce crime in short-term, but not likely in long-term because detention facilities cost much of the budget and it is not going to benefit the community. Since it is assumed that the total budget for justice reinvestment campaign in Burke is 50 units, an initial setting of 10, 25 and 15 units for Police Force, Community Investment and Family-Police Relations respectively is recommended.

Initial values:

Youth in town: 1200.

Criminals: 100.

Juvenile Detention: 100.

Violent families: 300

Detected violent families: 100.

This Model showcases the interplay between the Youth and Crime in Bourke with a monopoly of contributing factors.

The Groups and factors are explained in depth below.

With a total population of 3000 the the total youth population is estimated to 2000.

Youth: Initialing this encompasses 2000 individuals aged 15-25 years that are currently living in Bourke.

Crime: this denotes the number of youth involved in crime

Conviction: this includes youth that have been caught after committing a crime.

Youth in detention: the number of youth that have been detained for a period of time after being convicted of a crime.

Community program involvement: The number of youth that participate in community programs.

FACTORS (affecting the groups above)

Crime Rate: the rate at which youth commit a crime, this variable based upon 'alienation'.

Caught: the ratio of youth committing crime are caught. This is variable based upon the 'policing expenditure'

Alienation: a ratio reflecting the division between Bourke's youth and law enforcement. This variable is based upon the level of policing expenditure and community program expenditure.

Policing Expenditure: The respective amount of money (000's of dollars) allocated to tackle youth crime.

SLIDER

min: 5 ($5,000)

max: 50 ($50,000)

Community Program Expenditure: The respective amount of money (000's of dollars) allocated running community programs aimed to help Bourke's youth population.

SLIDER

min: 0 ($0)

max: 40 ($40,000)

By adjusting the policing and community program expenditure parameters using the sliders shows fluctuations between the groups. For example, by increasing policing expenditure will increase alienation, subsequently the crime rate will increase. Furthermore an increase in the proportion of youth committing crime that are caught, subsequently increasing the youth being convicted and in detention.

On the other using the slider to increase the expenditure on community programs, will see increase in the the number of youth involved in the programs. Also the level of alienation will decrease and subsequently reflecting in a reduced crime rate.

Time variable used in this model is Months. This is shown in the relative simulations.

Bourke's Youth Crime (Rowena Mackintosh 43661041)

Rowena Mackintosh

The complex systems model ‘Engagement vs Police Expenditure for Justice Reinvestment in Bourke, NSW’ evaluates the effectiveness of allocating government funding to either community engagement activities or law enforcement. In this model, it is possible for the user to designate resources from a scale of 20-100 and to also modify the crime rate for both adults and youth. Below, there are detailed notes that describe the reasoning and assumptions that justify the logic applied to this model. Similar notes can be found when stocks, flows and variables is clicked under the field ‘notes’.

Portions

Government statistics from the Australian Bureau of Statistics (ABS) show that Bourke Shire Regional Council has approximately 3000 residents, made up of 65-63% adults and 35-37% youths.

Crime Rate

Police variable is in the denominator to create a hyperbolic trend. The aim was to achieve a lower crime rate if police expenditure was increased, thus also a higher crime rate if police expenditure was decreased. The figure in the numerator can be changed with the ‘maximum crime rate’ variable which represents the asymptotic crime rate percentage. Where police = 100 the selected crime rate is maximised.

Avoiding Gaol

Originally the formula incorporated the police as a variable, where the total amount of convicted crimes was subtracted from the total amount of crimes committed. However, the constant flow of crimes from repeat offender/a created an unrealistic fluctuation in the simulation. I settled for a constant avoidance rate of 25%. This assumes that an adult or youth committing a crime for the first time is just as likely to avoid conviction as a repeat offender.

Conviction

It is difficult to predict in a mathematical model how many adults or youths are convicted of crimes they commit. I determined a reasonable guess of maximum 75% conviction rate when Police = 100. In this formula, decreasing police spending equates into decreased conviction rate, which is considered a realistic representation.

Released

It is assumed that the average sentence for a youth is approximately 6 months detention. For an adult, it will be assumed that the average sentence is 12 months gaol. The discrepancy is due to a few basic considerations that include 1. Adults are more often involved in serious crime which carries a longer sentence 2. youths are convicted with shorter sentences for the same crime, in the hopes that they will have a higher probability of full rehabilitation.

Engagement

Rate of adult/youth engagement was estimated to be a linear relation. The maximum rate of engagement, assuming expenditure = 100, is set to 80%. This rate of engagement is a reasonable guess with consideration that there will also exist adults who refused to engage in the community and end up in crime, and adults or youth that refuse to engage in the community or crime.

Boredom

Engagement Expenditure variable is in the denominator to create a hyperbolic trend. The aim was to achieve a lower boredom rate with a higher engagement expenditure, and thus a higher boredom rate with a lower engagement expenditure. The figure in the numerator of 25 represents the asymptotic boredom rate percentage, where if engagement expenditure = 100 the adult/youth boredom rate is maximised at 25%.

Description:
This model focuses on the youth population of the community of Bourke in Australia. It shows the crime development of the youth population depending on the relationships of the expenditure provided by the police and community, crime rate and release rate of Bourke, and the rate of atonement failure.

Initial Assumptions:

Youth in community: 1000
Mischievous youths: 200
Youth involved in crime: 140
Youth in jail: 80

How the Model Works:

1. Youth in Community
The model starts from being a youth in the community with no real motive which is affected by the community development expenditure. There are two paths that the youth can take, becoming bored of the community and staying as a normal youth with no motive in the community. There is a 70% chance of the youth becoming bored of the community and becoming mischievous as the community did not satisfy the youths' boredom.

2. Mischievous Youth
After transitioning to a normal youth to a mischievous youth, there are two paths that the mischievous youth can take. The non criminal activity path which is when the mischievous youth is not bored from the community anymore and proceeds back into the community, this path is affected by the community development expenditure. The second path is becoming involved with criminal activity and thus becoming a criminal, which is affected by the 40% crime rate of Bourke.

3. Criminal
After becoming a criminal youth, there are two paths that the youth can go down. The first path involves not being caught by the police yet and are still wondering around in the community at a 20% chance. This path is affected by the atonement failure variable as the criminal youth, despite going back into the community, is still willing to be involved in crime. The second path is getting caught by the police and is jailed at an 80% chance. This path is affected by the police expenditure used to catch the criminal youth.

4. Jailed
After being jailed by the police, the criminal youth can be released back into the community after their sentence has been completed, they can either still be involved in crime or a mischievous youth. The first path is failing to atone for their crimes even after spending a period of time in jail, with a 20% chance of happening. This path is affected by the atonement failure variable. The second path is being released back in the community at a 90% chance as a mischievous youth as they have learned their lesson in jail and will cease any criminal activities for the time being. After a period of time the released mischievous youth can take two paths, being involved with criminal activity again at a 40% chance or atoning for their crimes and becoming a non criminal youth with no ill-intentions at a 70% chance.

Background Information

Bourke is a town of 3000 people in the North West of New South Wales, about 750Km from Sydney.

The state government is implementing a new measure to prevent further crime committed by installing community programs such as sporting clubs, and classes to develop relationships among police and the community.

Many youth were going from home to juvenile detention and back, and many adults were on a similar roundabout between the community and jail.

Community development programs hopefully will reduce the levels of domestic violence among adults, and petty crime among the town’s youth.

Model Explanation

Firstly, you notice Adult and Youth population is separated and assumed that 50% of adults will commit crime whereas 20% in youth. A certain percentage is given for the number that is guilty and not guilty. Guilty, will receive certain punishment according to their age category and after their sentence is served, they go back to town.

Policing Expenditures shows how many officers are needed to reduce the amount of crime. Officers are called when a crime/mischief is committed, whether they're caught or not and found guilty or not.

Stocks

Adult Population: Adults in Bourke

Youth Population: Teenagers in Bourke

Crime: Domestic Violence/Homicide

Mischief: Petty Crimes

Jail: If Guilty, adults are sent to jail

Juvenile Detention: If guilty, youth are sent to detention

Community Programs: Sporting clubs, developing interpersonal relationships among police and “at risk” households, and teaching trade-skills

Assumptions

Adult Population: 2100

Youth Population: 900

Adult Crimes: 50%

Youth Mischief: 20%

Goal

The aim of this model is to illustrate the affects of implementing change i.e. policing/government aid within a community

Trends

The increase of Government Aid and Policing Expenditures decreases the crime performed in the community.

We can see a positive outcome from this and can take into account the affects of proper execution by the state government

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.

This model displays the effects of youth crime and the influence of community expenditure, social support, and policing in the town of Bourke, NSW.

The traditional lifestyle for youth in this town involves either a chosen path of committing crimes, or, that of community activity and various forms of education.

The model has been designed to mimic a system where community expenditure and support services are adopted in order to inject a positive lifestyle for the youth population. The phenomena studied in this simulation is the balance between policing, community support and social influence versus not using them.

Assumptions
-1000 Youth Population

-Youth are either influenced by criminal activity or by productive educational activities.

- Adoption rate of community activities is influenced by personality, relating to current personal skill level of youth and willingness.

-If youth you do not become involved in community activity or some form of Education, then they turn to the path of crime.

-Punishment facility time is up to 12 months with a 2 year probation period

-Community expenditure and support only begins in the probation period, unless “Juvenile Support” slider is used.

-For the purpose of this study on youth crime and support before a crime is committed, we do not include a possibility of relapse in the rehabilitation phase.

STOCKS

Youth
Crime – all offences committed by those under 18
Punishment Facility – juvenile detention
Probation – release from punishment
Education system – various programs

VARIABLES

Policing Units – Policing Bourke's criminal activity, and convicting after a crime has been committed.

Juvenile Support Units – The variable change in crime IF the community funds Support Units for youth before a crime is committed.

Social Support Units – The number of social support units available for released offenders during rehabilitation phase.

Community expenditure – the amount of time and money being spent on social services and policing.

Birth rate, crime rate, dicharge rate, recidivism & conviction rate

INTERESTING RESULTS

Slide any of the 3 variables to the extreme.

This model shows that adoption rate of a positive lifestyle is directly influenced by social influences.

1/ Juvenile Support Unit impact

Press Simulate.

Slide Juvenile Support Units to the extreme. Simulate again.

Juxtaposition of Juvenile Support impact on Behavior Graph shows that Crime and Reoffend rates drop significantly. More people turn to law-abiding positive activity.

This will again all change with the manipulation of the Social Support unit slider…..

2/ Social Support Unit impact

Social Support Units only influence those released from the Punishment facility. The more social services on hand to support rehabilitation phase the less chance of committing crime for the second time, with Reoffend rates dropping significantly when the Social Support Units Slider is adjusted to the extreme.

Rehabilitation rates only increase marginally, in spite of more social support feeding into that phase.

The greatest impact is shown on Law-Abiding and Crime. How could this be? A logical conclusion is that there is a finite number of youth in the community and those who have received positive social support during a learning phase of rehabilitation, then go on to influence their friends, their family, and have a positive influence on those around them.

3/ Police Unit Impact

Slide Policing Units to the extremes. Simulate. Policing Units Graph shows there is a significant decrease in Reoffend rates, and a higher rate of Conviction.

Curiously, rehabilitation rates drop and crime rates go up. How could this happen? A logical conclusion is that conviction and punishment is not a crime deterrent. It needs the added influence of social support services for there to be a positive impact on decreasing criminal instincts and activity on the whole.

Conclusions

Social support and home visits need to happen in the flow between Youth Population and Crime - “Juvenile Support Units”.

Investment in youth via these juvenile social support officers before they commit an offence, limits the amount of criminal activity over time. So, crime effectively decreases with the direct influence of social services at a young age.

Equally, with more police presence in the community, for those tempted to re-offend, they have a deterrent.

The most efficient management of the community issues faced in Bourke however lies with a combination of both Policing and Social Support services at all levels within the community.

Daniel Chalk

Bourke Youth Crime Model

This simple model is designed to simulate crime amongst youth in the country town of Bourke, Australia.

Bourke has a youth population (under 24 years of age) of 998 (ABS, 2015). These 998 persons begin arbitrarily split between the general population [Bourke Youth], youth in the football club [Football Club], youth engaged in criminal activity [Criminals] and incarcerated youth [Prisoners]

The rates of transfer between these blocks are determined by several logical mechanisms which are explained below. All calculations are rounded for the obvious reason that populations are necessarily integer values. To facilitate investigation into the interaction between variables, only Police and Funding are adjustable. Any other inputs would unnecessarily complicate the model, and degrade its usability and usefulness.

Observations:

Police and Funding have an interaction that determines the outcome for criminals in the simulation. At a funding multiplier of 1 (standard) and with minimum police, Criminals outnumber youths by the end of the simulation. As the funding is decreased, this threshold increases until a funding multiplier of 0.2, where even the maximum number of police cannot control the criminal population.

Perhaps most interestingly, the equilibrium prisoner population depends on the sports club funding multiplier, not the number of police.

An interesting comparison can be found between setting the funding multiplier to 1.5 and police to 100, and setting funding to 0.3 with police at 225. This comparison is an ideal use for this model, as it reflects the benefits from community engagement seen in the case study.

Rates:

Commit Crime: The crime rate in Bourke is modelled to be dependent on several factors, principally the number of police in Bourke (a greater police presence will reduce crime). It is also assumed that a greater general youth population will increase the rate of crime, and that participation in the football club (or interaction with other engaged community members) will discourage crime. For these reasons, the rate of criminalisation is modelled with the equation:

Round([Bourke Youth]^2/([Football Club]*[Police]+1))

Arrested: The arrest rate is determined by a factor of the number of police available to charge and arrest suspects, as well as the number of criminals eligible for arrest. A natural logarithm is taken for police, as police departments should see diminishing returns in adding more officers. A logarithm is also taken of criminals to allow it to factor into the rate without swamping the effect of police. Thus, the rate is calculated with:

Round(ln([Police]+1)*5*log([Criminals]+1))

Released: The release rate is a straightforward calculation; it is set to increase with the square of the number of prisoners to keep the maximum number of inmates low. This is because Bourke is a small town with a small gaol and it would have to prematurely release inmates as the inmate population overflowed. Thus it is calculated with:

Round(0.001*[Prisoners]^2)

Recruited: The Football recruitment rate is assumed to be dependent on the population available for recruitment, and the funding received for the football club. A better funded club would recruit youths in greater numbers. Consequently, the recruitment rate is calculated with:

Round(ln([Bourke Youth]+1)*[Funding Modifier]+1)

Dropout Rate: The dropout rate from the football club is assumed to be dependent on the number of players (a proportion should quit every season) and the funding of the club (a well funded club should retain more players. Thus it is calculated with:

Round(1+ln([Football Club]*10/([Funding Modifier]+5)))

Self Adjust: A small leak flow to represent those criminals that cease their criminal activity and return to the general population.

Crime, Policing and Community Programs involving Youths in Bourke

Lauren Attwood

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!

Justice Reinvestment in Bourke

About/Background:

This model provides a simulation of the youth where it depicts the interactions and activities amongst the parameters in this situation. The town of Bourke have been dealing with the issue of a high crime rate amongst the young and many being locked up which as a result has shattered families. Now the government is deciding on how they would approach spending their money on and this model will depict the various solutions and give an indicator of how it effective it maybe.

Initial Values:

Home - 1000

Juvenile Detention - 0

Sporting Clubs - 0

Trade Skills - 0

Petty Crime - 0

Interpersonal Relationships - 0

Variables:

Youth Redevelopment Expenditure: The value that the state government are able to spend on trade skills and sporting clubs

Interpersonal skills: The rate at which how proficient a youth can be with their interpersonal relationships with others

Police: The number of police that are available in the town of Bourke

Rehab: A certain proportion of those that are in the juvenile detention, will be rehabilitated

Assumptions:

- The youth population (Home) will be 1000 (a third of the population of Bourke's 3000)

- When there is an increase of police it will result in an increase amount of youths being caught as well as a decrease in crimes being committed

- When someone goes to juvenile detention and understood their mistakes, when they are released they will no longer have the urge to commit a crime

- Youth Redevelopment Expenditure will affect participation rates and reduce crime rates

- Youth Redevelopment Expenditure is spread equally to sporting clubs and trade skills

- Youths that participate in sporting clubs, trade skills and Interpersonal relationships will be less likely to commit a crime

- Those in juvenile detention will be released after a period of 6 months where a proportion of them have been rehabilitated.

Interesting Results:

1. If all the sliders are set to half (Police - 30, Rehab - 50, Youth Redevelopment Expenditure - 50, Interpersonal Skill - 50), Sporting Club appears to be the most popular community development program for youths

2. If police and Youth Redevelopment are to its max and rehab and interpersonal are set to 0, there seems be a much lower rate of crime being committed as well as higher number of youths participating in sporting clubs

3. If police was to be at its lowest (10), youth redevelopment at 100, rehab and interpersonal skill at 50, crime appears to be low while maintaining high rate of youth participating in sporting clubs and trade skills.

Srinivas Nalla

Background

The town of Bourke is in north-west New South Wales and became the first pilot site to implement an Aboriginal-let model of justice reinvestment in 2013, known as the Maranguka Justice Reinvestment Project. The project aimed to demonstrate that sustainable outcomes can be achieved by redirecting funding to the underlying causes of youth crime.

Model explanation

This complex systems model depicts the relationships between different players and helps simulate youth crime patterns when influenced by funded community engagement activities, fluctuating levels of alienation, and police funding over a period of 2 years. The funding of community engagement activities aims to increase youth participation and therefore reduce the rate of criminal activity.

Assumptions

75% of Bourke’s youth are disengaged from society.

25% of Bourke’s youth are engaged with society.

50% of Bourke’s engaged youth are not interested in the community activities.

60% of disengaged youth are alienated.

Police expenditure: 30

Community engagement expenditure: 60

Stocks

Youth of Bourke
Total youth population in Bourke. We are assuming there are 500 youths susceptible to committing crime within Bourke.

Community activities
Community programs aimed at youths which could include sports, arts and cultural programs, counselling, support groups, learner driving school, school holiday programs and health and development checks.

Disengaged Youth
Youths who are not engaged in positive community activities and are at risk of committing criminal activities. These youths may be affected by domestic and family violence, drugs, alcohol or abuse.

Engaged Youth
Youths who are engaged in society in a positive way. The aim of this program is to have all youths positively engaged in Bourke’s community.

Crime
Youths who have committed a criminal offence.

Prison/detention
Youths who are found guilty of a criminal offence and are now in prison or detention.

Rehabilitation
Youths who have left prison/detention and are now attending rehabilitation programs. This rehabilitation should decrease the likelihood of youths re-offending.

Variables

Police expenditure
Funding for police presence to decrease the number of youths participating in criminal activities and whether they are convicted and imprisoned. If youths are imprisoned, police expenditure can also help move them towards rehabilitation to lessen the chance of re-offence.

Community engagement expenditure
Funding of community activities aimed at the youth of Bourke. These activities are designed to positively impact the lives of youth and lessen the chance of alienation and disengagement from the community.

Alienation
Contributing factors to alienation of youths in Bourke include domestic and family violence, drugs, alcohol, abuse, homelessness, and lack of education.

School/VET attendance
The rate at which Bourke’s youth attend school or vocational education and training courses (VET) to further their education and increase their engagement in the community.

Conclusions

This complex model indicates the impact of only a few variables, yet there are many more that can be considered. However, this model shows that over a period of 2 years, the combination of community engagement funding, police funding and education can improve the lives of Bourke’s susceptible youth. The most significant impact is made by the community engagement funding. If this funding is decreased, the rate of engaged youth decreases, and the rate of disengaged youth does not improve.

MKT563 Ass 4 - Complex systems - Justice Reinvestment Project in the town of Bourke

Renee Dickens

Justice Reinvestment in Bourke

The Model:

I have used a Systems Dynamic model which is made up of stocks, flows, and primitives.
A linear function (Straight Line Method) has been created to determine the impact of adjusted expenditure levels in policing and community development. The town of Bourke experiences extremely high youth detention levels. The cause of this detention level is said to have many contributing factors. These include, the at home environment of the youth, with many households experiencing domestic violence incidents. While other contributing factors are the lifestyle of the youths external environment, with many youth not attending school, not having their license, and being unemployed. Each of these factors only increase the youth crime rate in Bourke. In order to combat this, research into crime prevention has been implemented in Bourke. Increased expenditure on community development programs like domestic violence consultation groups, football clubs, free driving lessons and talks between elders and the youth have been implemented in the hope to reduce youth in detention.
My model demonstrates the effect of increased expenditure on community development verse increased expenditure on policing. The ultimate outcome would be to establish a balance between expenditure on policing and expenditure on community development, thus resulting with as little youth in detention as possible.

Assumptions:

Bourke total population: 3,000
Bourke total youth population: 2,000
Initial Value are as followed -
Bourke youth in community: 500
Bourke youth involved in crime: 250
Bourke youth in Juvenile detention: 250
