What percent of the U.S. and Los Angeles population describes themselves as various ethnic group
HAS TO BE 2-3 paragraph response!
Description: This exercise allows you to explore what percent of the U.S. and Los Angeles population describes themselves as various ethnic groups.
Instructions: Go http://www.census.gov/quickfacts/ (Links to an external site.)
Scroll down til you get to race in the table.
Look at the numbers for the United States.
Write Up: Write up a commentary on what these numbers mean to you, if they surprise you, if there are implications to them, and anything else you would like to include. Given how much the ethno-racial makeup of Los Angeles differs from the United States as a whole, do you think this has an effect on how you perceive race relations?
Mathematics Question
1. Krylov Subspace: [5 marks each]
Consider the linear system Ax
=
b where A ∈ R
n×n
is non
–
singular and b ∈ R
n
.
(a) Consider a generic Krylov subspace method that generates iterates as
xk ∈ x0 + Kk (A, r0), 1 ≤ k ≤ t,
where r0
=
b b Ax0 and t is the grade of r0 with respect to A. Show that
Span{r0, r1,
. . .
, rkk1} ⊆ Kk (A, r0), k ≤ t, where ri
=
b b Axi
.
(b) Assuming A 0, consider the oblique projection framework where Wk
=
AKk,
and show that Span{r0, r1,
. . .
, rkk1}
=
Kk (A, r0), k ≤ t.
(c) Now, assume A is symmetric (but not necessarily positive defifinite), and consider
again the oblique projection framework. Show that hr0, rki
=
krkk
2
, 0 ≤ k ≤ t.
(d) Consider the case where A is symmetric (but not necessarily positive defifinite), and
recall the tridiagonal matrix Tk from the Lanczos process. Show that
Tk 0 ⇐⇒ hw, Awi > 0, ∀w ∈ Kk (A, r0)
.
2. Conjugate Direction Methods: [5 marks each]
For a given A ∈ R
n×n
, A 0, a collection of k non
–
zero vectors {p0, p1,
. . .
, pk}, where
k ≤ n n 1, are called A
–
conjugate, if
hpi, Apj i
=
0, i
=
j
.
(a) Show that {p0, p1,
. . .
, pk} are linearly independent.
(b) Given a collection of linearly independent vectors {v0, v1,
. . .
, vk}, design a Gram
Schmidt procedure to form a set of A
–
conjugate vectors {p0, p1,
. . .
, pk} such that
Span {v0, v1,

=
Span {p0, p1,

Describe and compare the roles of the nurse, or health professional, in each country.
Describe and compare the roles of the nurse, or health professional, in each country. This should be 1-2 paragraphs (at least 3-5 sentences per paragraph).
Describe and contrast public health and healthcare in the U.S. with public health and healthcare in one other country.
Describe and contrast public health and healthcare in the U.S. with public health and healthcare in one other country. You should have a paragraph (at least 3-5 sentences per paragraph) for each country (the U.S. and the one country you choose to study).
Write and share your story is to grow in who you are and at the same time, gain a more profound understanding of the people who will share their stories with you in this course.
Assignment Introduction
One of the powerful experiences of GS 420 is the sharing of life stories. By sharing your own story, you begin the journey of your own self-discovery and self-reflection. We cannot possibly begin to understand the disability experience of someone else unless we can examine our own experiences with life. Everyone’s story is unique, and yet, we all struggle with life’s challenges and we all care about issues that are meaningful to us. This experience of storytelling can bond us together in our diversity. To write and share your story is to grow in who you are and at the same time, gain a more profound understanding of the people who will share their stories with you in this course.
Some of you will feel more comfortable with writing a timeline of your life so far, dividing your life into periods. Others may want to describe your life thematically, or perhaps allegorically. You get to choose how you share your story.
Your story is considered confidential and will not be shared with anyone other than the instructors and teaching assistants (who assist with grading during the semester). You are not required to include parts of your story that you are uncomfortable sharing. However, sometimes sharing or exploring challenging areas of our life can be a step in pressing through.

If you do not own a kitchen scale, you can do this part in week 4 after you pick up your lab kit and have your pocket balance.
Write a summary of your changes and overall editing/rewrite process.
OPTION #2 INSTRUCTIONS
Please note if you do not attend the writing center, you will be writing a second portion of this assignment, titled, “Article Review Application” that you will include just after your “Narrative Summary” segment of the assignment.
1. Rewrite the paper in accord with feedback from your instructor/CA and from your scored rubric as well as information garnered from the article linked below. WRITE ALL CHANGES IN RED “INK” (RED FONT). Failure to write all changes in red ink will result in a considerable point-deduction. Do not include “comments” or “track changes” in your assignment submission. DO NOT “TRACK” your changes/edits; submit ALL changes/edits in RED FONT. (40 points)
2. Write a summary of your changes and overall editing/rewrite process. Please use appropriate grammar and APA format in this summary – of note, you MAY WRITE in the first-person in the narrative summary as this section is about your personal reflection on the rewrite of a formal writing assignment. For this section, you create a page after your reference page and use the subheading “Narrative Summary” to delineate this section. (40 points; minimum 300 words)
3. Read this article: httpswaccolostateeduwritingspacesdasbenderpd://../books/2/–critical-thinking (Links to an external site.) & Write about your experiences with our first writing assignment (WA-1) using the article above to guide your review (40 points; minimum of 200 words); make certain to:
- Place this summary after your “Narrative Summary” and label this section “Article Review Application”
- Respond to these instructional prompts in your “Article Review Application”:
- Discuss the core critical thinking skills (Facione & Gittens, 2016) you employed in writing the WA-1.
- What seemed to be the most difficult portion of the assignment?
- What approaches did you use in your attempts to overcome this difficulty?
- Cite the article in-text and in your reference section in APA format.
