    Study Notes

    Aims of Punishment

    • Punishment is a key aspect of the criminal justice system, ensuring consequences for crime and upholding societal order.
    • The Criminal Justice Act 2003 (s142) outlines two main aims of sentencing:
      • Punishment of the offender: Holding the offender accountable for their actions.
      • Reduction of crime: Deterrence, rehabilitation, and incapacitation are all aimed at reducing crime.
    • Retribution, often described as "an eye for an eye", is about justice and making the offender suffer in proportion to the harm caused.
      • This approach sees punishment as deserving and a consequence of the crime, reflecting society's outrage.
      • Just Deserts theory by Von Hirsch emphasizes that punishment should be proportionate to the crime and express blame or censure, addressing the wrong done to the victim.

    Deterrence

    • General Deterrence: Aims to discourage potential offenders by demonstrating the consequences of criminal behavior.
      • This is achieved by making punishment public and visible, serving as a warning to the public.
    • Individual Deterrence: Aiming to prevent the specific offender from reoffending by making them experience the unpleasant consequences of their actions.

    Incapacitation (Public Protection)

    • This aim focuses on removing the offender from society to protect the public while they are incapacitated.
    • This can involve imprisonment, restraining orders, or other measures to prevent further harm.

    Reparation

    • This aims to address the harm caused by the offender and restore the victim's sense of justice.
    • Reparation can involve various measures like:
      • Financial compensation: Repaying the victim for damages or losses.
      • Community service: Performing work to benefit the community, demonstrating responsibility and acknowledging the impact of their actions.
      • Apology: A sincere expression of remorse and regret for the harm caused.

    Scenario Analysis

    • In the scenario provided, the offender, an 18-year-old male, broke into a garage, causing property damage and causing emotional unease to the victim.
    • Reparation would be the most appropriate aim in this case, focusing on restoring the victim's sense of justice:
      • The offender could be ordered to make financial compensation for the damage to the garage and fence.
      • Community service could be used to benefit the local community and demonstrate responsibility.
      • A sincere apology to the victim should be encouraged, acknowledging the harm caused and expressing regret.

    Schizophrenia

    • Affects about 1% of the population with varying severity
    • Occurs across the globe, but is significantly more prevalent in the US and Europe compared to third world countries
    • Prevalence is slightly higher in men than women with an estimated 7:5 ratio
    • Men experience more severe symptoms and an earlier onset (early 20s versus late 20s)

    Positive and Negative Symptoms

    • Positive symptoms are behaviours present that should be absent
      • Psychotic (e.g., hallucinations, delusions)
      • Disorganized (e.g., disorganized speech and behaviour)
    • Negative symptoms are behaviours absent that should be present
      • Weak social interaction
      • Diminished emotional expression
      • Limited speech
      • Impaired working memory
    • Negative symptoms are generally stable over time and difficult to treat

    Heredity

    • Twin studies suggest a genetic factor, but not attributed to a single gene
    • Monozygotic (identical) twins have a significantly higher concordance rate (agreement) than dizygotic (fraternal) twins
    • However, even monozygotic twins only have a 50% concordance rate
    • This suggests other factors contribute to the development of Schizophrenia
    • Observed differences between dizygotic twins compared to siblings suggest potential prenatal or postnatal environmental influences

    Genes Associated with Schizophrenia

    • Neurotransmission
      • Dopamine receptors: DRD1, DRD2, DRD4
      • Serotonin production: TPH1
      • Serotonin transporter: SLC6A4
      • NMDA glutamate receptor function: DAO, GRIN2B
      • Glutamate release: DTNBP1
      • GABAA receptor: GABRB2
      • Enzyme that deactivates neurotransmitters (e.g., dopamine): COMT

    Gene-Environment Interaction

    • Individuals exhibit varying susceptibility to both negative (risk-provoking) and positive (development-enhancing) environmental conditions
    • Some individuals may experience higher sickness leave due to poor environments than others in similar conditions
    • Potential contributing factors include:
      • Stress hormones
      • Neuro-plasticity

    Tryptophan Hydroxylase-2 (hTPH2)

    • A specific mutation in the hTPH2 gene is found ten times more frequently in major depression patients compared to non-depressed individuals
    • This mutation results in a dysfunctional protein, causing an approximately 80% loss of function in serotonin production
    • Depressed patients with this gene mutation may not respond to antidepressants that work by blocking serotonin reuptake, as insufficient serotonin is produced

    Antidepressant Drugs

    • Many psychiatric medication discoveries were accidental
    • Categories of antidepressants include:
      • Tricyclics
      • Selective serotonin reuptake inhibitors (SSRIs)
      • Monoamine oxidase inhibitors (MAOIs)
      • Atypical antidepressants

    Tricyclic Antidepressants

    • Block transporter proteins responsible for reabsorbing serotonin, dopamine, and noradrenaline back into the presynaptic neuron after release
    • Example: Imipramine (Tofranil)
    • Also block histamine receptors, acetylcholine receptors, and certain sodium channels

    The Dopamine Hypothesis

    • Schizophrenia is associated with excessive dopamine activity in the brain
    • Supporting Evidence: Amphetamine overdose causes psychotic behaviour nearly indistinguishable from Schizophrenia, including hallucinations and paranoid delusions, by increasing dopaminergic activity
    • Research indicates increased activity specifically at the D2 receptor

    Limitations of the Dopamine Hypothesis

    • Direct measurement of dopamine and its metabolites generally show normal levels in people with Schizophrenia
    • Antipsychotic drugs block dopamine quickly, within minutes, but their behavioural effects take much longer, building gradually over 2 to 3 weeks

    Dopaminergic Pathways in the Brain

    • Mesolimbocortical System: A set of neurons that project from the midbrain tegmentum to the limbic system

    The Glutamate Hypothesis

    • Schizophrenia is partially attributed to deficient activity at glutamate receptors, particularly in the prefrontal cortex
    • In many brain areas, dopamine inhibits glutamate release, or glutamate stimulates neurons that inhibit dopamine release
    • This implies increased dopamine can have effects similar to decreased glutamate

    Glutamate Hypothesis Supporting Evidence

    • Lower than normal glutamate release and fewer receptors observed in the prefrontal cortex and hippocampus of individuals with Schizophrenia
    • Phencyclidine (PCP), a drug that acts as an NMDA receptor antagonist (blocking its activity), supports the glutamate hypothesis
    • PCP-induced behavioural effects are similar to those seen in Schizophrenia, suggesting a potential role of NMDA receptor dysfunction

    Genes Associated with Schizophrenia (continued)

    • Development
      • Enzymes involved in neural development: MTHFR
      • Axon guidance: PLXNA2
    • Neural Damage
      • Neurodegeneration: APOE
      • Immune and inflammatory responses: IL1B, HP
      • Gene mutation prevention: TP53
