Feminist Retelling of Bluebeard in Angela Carter’s ‘The Bloody Chamber’
Angela Carter’s “The Bloody Chamber” is based on the legend of Bluebeard. Carter preserves the legend’s plot, casting the Marquis in the role of Bluebeard, who kills his wives and stores their corpses in a secret chamber. Like Bluebeard, the Marquis entices each new wife to explore the forbidden chamber and then kills her once she has discovered his secret. Carter goes so far as to reference the Bluebeard legend toward the end of “The Bloody Chamber.” When the heroine’s mother storms the Marquis’

Curse of Dimensionality
7.0 AM; 7.1 Curse of Dimensionality (Richard Bellman): The problem of estimating f becomes vastly harder as p, the dimension of x, increases.
Nonparametric regression model: y=f(x)+e
Minor assumptions:
- The xi are measured without error.
- The ei are independently and identically distributed (i.i.d.) with mean 0.
- Variance of the ei values = unknown constant σ.
Common assumptions:
- f is in a Sobolev space (functions with bounded derivatives).
- f has a bounded number of discontinuities.

Impulse Response
n =- 10:1:30; b = [-1 2 3 6 ...]; A = 1, x = zeros (1,41), x (11) = 1, y1 = filter (B, A, x), stem (n, y1), grid;
Zero-Pole Plot (Zerpol)
function [zeros, poles] = zerpol (B, A); bs = roots (B), as = roots (A); zeros = bs; poles = as; polar (angle (bs), abs (as), 'x') hold off;
Frequency Response (Respfrec)
function [module, phase, frequency] = respfrec (B, A, nfrec) linespace frequency = (0,0.5, nfrec), b = B (length (B): -1:1); a = A (length ( A): -1:1); polyval numerator = (b, exp
Computer Systems and Network Security Essentials
Why Aren’t All Computer Systems Secure?
- Cost/Benefit Issues
- Security Costs
- Users perceive no personal threat to themselves
- Ignorance
Legacy and Retrofitting
- We are constrained by legacy issues:
- Core Internet design
- Popular programming languages
- Commercial operating systems
- All developed before security was a concern
- Retrofitting security works poorly
Problems With Patching
- Usually done under pressure:
- So generally quick and dirty
- Tends to deal with obvious and immediate problem:
- Not with underlying cause
- Hard
Phonetics: Syllables, Consonants, and Pronunciation
Syllables
A syllable is a unit of organization for a sequence of speech sounds. A syllable is made up of a syllable nucleus (most often a vowel) with optional initial and final margins (typically, consonants). The parts are onset and rhyme; within the rhyme, we find the peak (normally a vowel) and coda (any consonants following the peak). Not all syllables have all parts. The smallest possible syllable contains a nucleus only. A syllable may or may not have an onset and a coda.
- Onset: Any consonant
Econometric Data Analysis: Types, Models, and STATA Commands
Econometric Data Types
- Cross-sectional: Samples at a given point in time or current period.
- Time series: Variables over time; the ordering of observations is important.
- Pooled cross-sectional: Two or more cross-sections are combined, e.g., comparing variables across two different years. Used to evaluate policy changes.
- Panel/Longitudinal data: The same cross-sectional units are followed over time. Can be used to account for time-invariant unobservables. E.g., each city has two observations in two different
