Deflation, Fiscal Policy & Aggregate Demand Impacts
Understanding Deflation and Saving
Deflation is a persistent fall in the average price level within an economy, representing a negative rate of inflation (where the price level, P, falls).
Saving is defined as income that is not spent; it is present consumption forgone. Saving acts as a withdrawal from the circular flow of income, often involving money stored in financial institutions.
Recession, Aggregate Demand, and Unemployment
During an economic recession, there is typically a reduction in Aggregate

Phage Structure and Components
Most bacteriophages (phages) possess a distinct structure. Tailed phages, comprising about 95% of known phages, have double-stranded DNA (dsDNA) enclosed within a protein capsid shell. The majority feature a tail, which can be:
- Long and flexible
- Long and contractile
- Short
An adsorption apparatus, including tail fibers and tail spikes, facilitates attachment to host cells.

Positivism’s Appeal in Criminology
Positivism insists that societal consensus exists; therefore, deviant behavior results from inadequate socialization and requires therapeutic correction. The challenge lies in how to achieve this. The proposed solution differentiates between those capable of free choice (having internalized societal norms through socialization) and a deviant minority whose behavior is seen not as a chosen lifestyle, but as determined by factors beyond their control.

Understanding Statistical Variability and Distributions
Understanding Measures of Variability
Measures of variability indicate how much scores in a distribution vary, either from the mean or across the full extent of the distribution. It represents the spread of all the scores. Four measures of variability are discussed here: the range, the average mean deviation, the variance, and the standard deviation. These measures can reveal the consistency or similarity of the scores in a distribution and the extent to which the mean truly represents all of the

Python File Handling Basics
Common modes for opening files:
open(filename, 'w'): Open for writing (truncates file if exists, creates if not).open(filename, 'r'): Open for reading (default mode).open(filename, 'a'): Open for appending (creates file if not exists).
Common file handle (fh) methods:
fh.read(): Reads the entire file content.fh.readline(): Reads a single line from the file.fh.readlines(): Reads all lines into a list of strings.fh.write(string): Writes a string to the file.fh.writelines(list_
