This unit presented applications of the course material. The Unit VIII assignment is to write a report that addresses the following elements.
Ensure your paper is written coherently and that it addresses the requirements mentioned above.
Your course project must be at least four pages in length, and it must include a title page and reference page (title and reference pages do not count toward the minimum page requirement).
In addition to using the required unit resources article by Mor et al. and the unit lesson in your course project, locate three peer-reviewed articles from the CSU Online Library that focus on applications of the course material. At least two of the three sources must not have been used in any of your other assignments for this course. The articles must be no more than five years old.
Because this assignment requires you to reference peer-reviewed articles, you may find it helpful to review the library’s tutorial on How to Find Peer-Reviewed Resources. (Transcript for How to Find Peer-Reviewed Resources video)
Adhere to APA Style guidelines when constructing this assignment, including title page and in-text citations and references for all sources that are used. Please note that no abstract is needed.
Read the U.S. Chemical Safety Board (CSB) investigation report of the 2007 propane explosion at the Little General Store in Ghent, WV. The final report can be read/downloaded at the following link: https://www.csb.gov/assets/1/20/csbfinalreportlittlegeneral.pdf?13741
Additional information on the incident, including a video summary, can be found at the following link: http://www.csb.gov/little-general-store-propane-explosion/
Complete the assignment as detailed below.
Part I: From the information in the report, create a chart listing events and causal factors for the incident in Microsoft Word, Open Office, or a similar word processing software. If you choose to use a program other than Microsoft Word, be sure to save and submit the document as a Microsoft Word document (i.e., .doc, .docx). The objective of this project is to provide you with an opportunity to use this important and very practical analytical tool. The chart does not have to be infinitely detailed, but the key sequence of events should be charted as should the key conditions surrounding the events. Keep in mind that the purpose of an events and causal factors chart is to aid in identifying which conditions could be causal factors.
Use the charting procedures on pages 72–76 of your textbook to help you with this assignment. In addition, refer to the example events and causal factors (ECF) chart in the Unit IV Lesson for an example of this type of chart.
Part II: On a separate page, discuss the potential causal factors that are revealed in the analysis. How do these causal factors compare to the causal factors found in the CSB’s investigation report? Do you think more analysis is needed? This part of the assignment should be a minimum of one page in length.
Upload Parts I and II as a single document. For Part II of the assignment, you should use academic sources to support your thoughts. Any outside sources used, including the sources mentioned in the assignment, must be cited using APA format and must be included on a references page.
Useful hints: In Microsoft Word, you can use parentheses for events (events), square brackets for conditions [conditions], and brackets for the accident {accident}; you may also use a similar convention, such as color-coded text or the shapes that are available within Microsoft Word. Whatever convention you use, be sure you provide some kind of key.
Carbon dioxide is held responsible for much of global warming. For this discussion, conduct independent research on technological innovations that have been proven to reduce carbon dioxide emissions.
Note the following as you begin your research:
In this posting, complete the following:
Discussion 1
Calculate your personal ecological footprint using Global Footprint Network’s Footprint Calculator and briefly summarize your results. Were you surprised by any aspect of your ecological footprint?
Discussion 2
Discussion 3
Then, search Science Daily or a news story about a natural science topic that’s less than six months old. Make sure to choose a story that interests you, because you’ll use this news story for all the projects in this course.
Once you’ve chosen a news story, summarize the main ideas from the article. Then, draft two questions that a natural scientist might ask about the topic. Include both the summary and the two questions in your initial post. As you write your questions, think about what you’ve learned about the natural sciences and scientific thinking in the module overview. For instance, if you chose an article on volcanic eruptions, you might ask: what causes eruptions to happen and how do we predict when they’ll occur? Make sure to include the news story title and a link to it in your post.
This assignment consists of two parts: you will be declaring the topic for the Final Paper (in the abstract)
and finding ONE quantitative journal article to review that is related to the topic you have chosen for the
Final Paper. Your topic must be relevant to the field of counselling psychology.
The purpose of an article review is to communicate the main points of a study and to discuss both the
implications and strengths and weaknesses of the design. The review is not meant to re-iterate the
details of the study and paraphrase each and every point; rather, it should summarize and discuss the
study. These assignments should be seen as an opportunity for you to demonstrate your understanding
of the course concepts, particularly in the Discussion section. Quotes should be used sparingly or not at
all. The JAR you will complete for this assignment should be about 1.5 pages in length. There are no
penalties for going slightly over this limit, but the final length should be close. As a rule of thumb, aim to
write about 1/3 page for each of the five main section headings in the template (Introduction, Method,
Results, Implications, Discussion). Use quotes sparingly, if at all; they will not be counted for content or
length.

Land Subsidence
Introduction
Of all water that reaches the surface of the earth from all types of precipitation, some runs off as stream
flow, some is evaporated from land and water surfaces, and some is transpired by vegetation. It is the
purpose of this exercise to consider some aspects of what happens to the rest of the water – that which
enters the ground. The water may remain in the ground from a period of days to thousands of years.
Because of increased demand on groundwater supplies, many places in the world today are
experiencing groundwater related problems.
What is Groundwater?
Some precipitation infiltrates the ground and percolates downward through voids (pores, fractures,
crevices, and other spaces) in the soil and rock. The water in these voids is called groundwater. Porous,
water-saturated layers of sand, gravel or bedrock through which usable groundwater flows are called
aquifers. Any area of land through which water passes downward or laterally into an aquifer is called a
recharge zone. Some materials are very impermeable to water infiltration, such as clay, shale or dense
igneous bedrock, and are called aquicludes. (See figure 1)
Figure 1
Aquiclude
Aquiclude
There are two types of aquifers: confined and unconfined. An unconfined aquifer forms when
groundwater collects above a layer of relatively impermeable rock or compacted clay, and the top of the
water represents the water table. A confined or artesian aquifer forms when groundwater is
sandwiched between two aquicludes. This type of aquifer is completely saturated with water under
great pressure and when a well is drilled into the confined aquifer, sometimes water is able to rise to the
surface without pumping. This type of well is called a flowing artesian well system. It is the confined
aquifer that is associated with land subsidence.
Land Subsidence
Mexico City, Tokyo, Houston, Las Vegas, several areas of Arizona and California are experiencing serious
problem as a result of land subsidence. Land subsidence or sinking of the land surface can be due to the
removal of underground water (groundwater mining). When many wells are drilled into the aquifer,
pumping removes water from the aquifer and lowers the hydrostatic pressure (water pressure). This
reduced hydrostatic pressure in the pore spaces of the sediments result in the compaction of the aquifer
and in the gradual lowering of the land surface. If the water is replaced in the aquifer the increased
hydrostatic pressure will return the beds of sands and gravel to their original form, but once compacted
the clays and silts of the confining bed will not expand to their original thickness resulting in a lower
surface elevation. (See figures 2 and 3.)
Figure 2
Land subsidence can cause problems such as flooding along coastal areas, as well as structural damage
to buildings, highways, and dams.
Subsurface mineral mining, petroleum mining, and a natural process called chemical (solution)
weathering of certain bedrock material can also result in land subsidence. Central Florida, Kentucky,
Tennessee, and a small area in Michigan have underlying limestone bedrock material. This limestone
bedrock is highly soluble and forms great underground caverns. In certain cases, the land surface
subsides until it reaches a point of failure and caves in. The resulting hole is called a sinkhole and can
reach great depths.
Although we can’t increase the earth’s supply of water, we can manage what we have more effectively
to reduce the impact and spread of water resource problems. Problems such as aquifer depletion, land
subsidence, saltwater intrusion, and groundwater contamination are growing concerns in the United
States as well as many developing countries.

Subsidence in the Santa Clara Valley, California
The first place in the United States where land subsidence due to groundwater removal was recognized
was in the Santa Clara Valley in California. The valley is a large, structural trough filled with nearly 2,000
feet of fined-grained sands. Below the depth of 200 feet the groundwater is confined in these fine-
grained aquifers by layers of clay. In the past, wells near Santa Clara flowed (artesian wells), but
pumping for irrigation resulted in a lowering of the water pressure surface by 150 to 200 feet by 1965.
The water level decline and subsequent surface subsidence continued, and, except for a recharging of
the aquifer between 1938 and 1947 due to the construction of surface reservoirs, was an increasingly
serious problem until a groundwater recharge program brought it to a halt around 1971.
