Vietnam War

20150828_112841-1The Vietnam War swayed voters left and right, some were pro war while others were vehemently anti war. Voters in 1966 were beginning to question the intentions of the war or if it was the best option. However, many voters were torn, they wanted the war to end but they wanted to win the war as well.

In this letter this citizen is concerned with the efforts of the United States government as most were during this period. People began to burn their draft cards, people started to riot in protest of the war, it no longer mattered if we won the war they just wanted to end it.

The Vietnam War paved the way for many anti war efforts, the war set an example for the rest of the wars to come. The Iraq war has then been compared to the Vietnam war because of the length of time that the war has lasted and because of the fuzzy details of what we are fighting for.

Digital technology and health care

Digital technology and health care
With today’s society technology is getting better and better. Today’s Technology is providing us with real time data on sleep, activity, social interaction, isolation, vital signs indicating stress and much more. A recent app was created to test students in order to provide inside to their mental health and academic performance. This study showed that the app correlates student depression level, stress and loneliness with academic performance without any participation from the user. In my opinion Technology is a good and bad thing. In this situation this app is able to monitor patients without them even worrying about when and what to do for monitoring. It also provides nurses with the correct time and activity that is occurring with the patient. However technology does have its problems and is not always correct. That’s why it is always important to check the patient rather then just relying on technology. One thing that pops in my mind when I read about technology is How it is improving in the nursing world. Most recently we have a new bar code scanner for medications which is helping improve medication errors. I have also seen technology being used with patient care. For example I have seen doctors and nurses go into patients rooms with iPads to teach them education on medications and therapy treatments. I can see in the future patients wearing a wristband that automatically takes their vital signs. Almost like the new Apple Watch word tracks How many hours of sleep you have, how many steps you walked in the day, and more. Lastly, I liked reading about the app designed for veterans undergoing rehabilitate. These vets can benefit greatly from such support when navigating difficult recovery after traumatic war injuries. In conclusion, technology is just going to keep improving ways to make the health care a safer place to help decrease errors and improve patient care.

Current diet ‘Heart Healthy’

For this week’s assignment we were required to pick a day and evaluate what we eat, focusing on the fat and sodium intake. Since I can remember what I ate yesterday, the following is the breakdown. [Fat (g) / Sodium (mg)]

Breakfast:

Iced coffee [ 4g / 50mg]
Sesame Bagel toasted with butter [5g / 600mg]
Fuji apple [0.4g /2mg]

Mid-morning snack:

Pluot [0g / 1mg]
Fuji apple [0.4g / 2mg]

Lunch:

Water (16 oz)
Luna Chocolate Peppermint Stick bar [5g / 125mg]

Dinner:

Trader Joe’s Beef Tamale [13g / 670mg]
Homemade pico de gallo (heirloom tomato and 1/2 red onion with fresh ground pepper) [0g / 3g]
Trader Joe’s sweet potato chips [ 10.5g / 0mg]
Water (12 oz)

Evening Snack:

Dilmah Ceylon Black Tea (w/ milk and sugar) [ 2g / 29mg]
Slice of Marie Calendars corn bread with honey butter [26g / 555mg]

Total fat:     66.3g                  Total sodium:        2,034mg

Imagine you were restricted of salt and fat intake – could you easily adjust ? According to the American Heart Association (AHA), the recommended fat intake is as follows:

Saturated fats should be less than 7% of daily calories (less than 16 grams in 2,000 calorie diet).
Transfats should be limited to less than 1% of your daily calorie intake (or less than 2 grams in a 2,000 calorie diet).

The AHA also recommends a heart healthy sodium intake will range from 1,500 to 2,400 milligrams each day.

When I compare my daily intake to the AHA’s recommendations, my sodium intake seems to be within the healthy range. I can not say for sure how my fat intake compares to the recommended range because I did not differentiate between monosaturated, transfats,  and saturated fats when I collected my data. I would like to think however, that since the majority of what I eat on a day to day basis is fresh fruits and vegetables it could be considered “heart healthy.”

Genres of CrossFit

CrossFit is a popular and unique discourse community in which frequent communication and participation is mandatory in order to fulfill the purpose of the community, and also achieve goals on a more personal level. In this discourse community, strength, integrity and dedication are not only encouraged but required. Members of the tight-knit CrossFit community actively interact with one another via many communication platforms. While the sport can be individual or team based, all participants belong to a CrossFit affiliate gym and attend group classes. Much of the communication that occurs within the community is face-to-face, in class. There, they are taught skills and proper techniques by a certified instructor, and also gain feedback and encouragement from other members. In-class instruction, teamwork, and friendly rivalries are a huge part of why communication is so beneficial to CrossFit’s success. People come together and share a common challenging, motivating experience in which members constantly strive to do better, and encourage others to do the same.
CrossFit founder Greg Glassman insists that “the communal aspect of CrossFit is a key component of why it’s so effective” (crossfit.com).

Personal, written, and digital communications are the foundation for building camaraderie and a team-based environment, necessary factors for achieving the ultimate goal of elite fitness. While face-t0-face interaction plays a major role in the CrossFit community, online communication platforms are hugely supportive in assisting members to expand their knowledge and participation within the discourse community. The discoursal expectations, which John Swales argues are created by genres, include understanding the terminology and body movements, as well as participation. In the article Materiality and Genre in the Study of Discourse Communities, Amy Devitt tells us that “Genres organize and generate the exchanges of language that characterize [discourse communities]” (Devitt, 550).

Genres are essential factors in the function of any discourse community. “You are probably already familiar with many genres, although you may not know them as such; perhaps your knowledge of genres is limited to types of books, whether mystery, horror, action, etc. Now I’m going to ask you to stick with me while I show you how knowledge of genres goes far beyond a simple discussion of types” (Dirk, 250 ). Kerry recognizes a prevalent intimidation and unfamiliarity with the rhetorical aspects of a genre and seeks to explain it in a more simplistic fashion. She leads us to find that genres may refer to any written text regarding a chosen subject matter.

Genres make the discourse community more accessible to its’ members. They inspire greater participation, and motivate members to become more knowledgeable, enhancing their expertise within the community and improving the ability to speak the specialized language. CrossFit members communicate effectively because they have developed a set of specific terminology relating to fundamentals, players, movements, workouts and equipment. Knowing the proper names for exercises is essential to one’s ability to participate in the class, and understanding the coaches critiques to ensure proper form and avoid injury. Written communications, or genres, are seen in class as well as online. Amy Devitt proposes that often, genres are intended to be read and analyzed by community outsiders. She quotes, “Surprisingly, many genres are designed within one specialist community for functions to be filled by nonmembers of that community,” (Devitt, 543). I would argue that the function of genres within the CrossFit community are centered around strengthening the knowledge and motivation within the community, rather than to entice or enlighten the non-participants. Below, I will break down the features and purpose of each of the most popular genres of CrossFit.

Whiteboards: Each CrossFit affiliate gym is unique in layout and design, yet maintain similar defining characteristics. Gyms, also interchangeably referred to as “boxes”, are quite unlike many popular athletic clubs. While most athletic clubs often hold much more equipment than actual participants, CrossFit boxes possess only the most basic weights and equipment. They rely much more heavily on how the body can perform a variety of movements with only a few different kinds of weights. Each box is centered around a whiteboard, as it is the primary form of written communication within the CrossFit community.
Whiteboards are used daily to write out each WOD (workout of the day), as well as warm-up weightlifting sequences, cool-downs, and optional competitor WODs. A very specific lexis is used in whiteboard communications, which would make it challenging for nonmembers or very new members to comprehend. Many abbreviations and acronyms are used to describe each workout such as AMRAP (as many rounds as possible), EMOM (every minute on the minute) or HSPU (hand-stand push ups). Members scores are also recorded on the whiteboard as a gesture of pride, and also to motivate participants to give each workout their all, knowing that results will be publicly shared. Many CrossFit gyms choose to have a separate whiteboard dedicated to a leader board. This holds the box’s top performers (usually one male, and one female score) for benchmark workouts or other personal records chosen to display at the owner’s discretion. This is an extra way to motivate crossfitters to perform at their highest competence levels, striving to get their name up on the leader board, or to m
aintain a position already held on the leader board.

This genre is used to assist with in-class participation. Coaches will write down different scalability approaches such as weight loads or rep schemes to allow members of all levels complete the workouts. Because the whiteboard is updated daily, it is intended to assist only those who came to class that particular day. However, many coaches choose to maintain an “online whiteboard” as well on their affiliate webpage, allowing those who missed a day to see what the WOD was and potentially make it up later in the week. While some of the other genres in the CrossFit community may be accessed and analyzed by community outsiders, the whiteboard is intended solely to communicate with not only community members as a whole, but specifically community members belonging to that specific gym.

CrossFit.com: Crossfit.com is the central communication hub for CrossFit members, both nationally and internationally. It is written both to inspire people who are interested in joining the community, and to provide information to those who already belong. The first thing to catch your eye on the home page is the Workout of the Day. Accompanied by the WOD is usually an inspiring picture of someone crossfitting in beautiful scenery, reaching a challenging weight goal, or collapsed after a brutal workout. The main page also contains links to CrossFit Journal, the CrossFit Games website, a schedule of coaching certification courses, and an extensive list of affiliate gyms. The sidebar holds a menu offering an abundance of information including:1a0cc119bfbd42b_689876_th
• What is CrossFit?: The theory behind the development of the sport. It defines CrossFit in the most basic way, as constantly varied functional movements performed at relatively high intensity. Included in this segment is a brief motivational YouTube video where community members contribute their personal goals and passions in terms of CrossFit. A gentleman at the end of the YouTube video gives my personal favorite explanation of what the sport is all about—“A fitness program where the reward for doing well is the ability to express your fitness in everyday life, in as many different planes, or as many different activities as you can possibly imagine. People walk through the door and say, where’s all the machines? We ARE the machines” (Let Me Tell You About CrossFit).
• FAQ’s: Examples include: What is a tabata? Where can I buy rings? How do I scale a workout?
• Exercises and Demos: This section includes short videos of the foundational movements to give a visual demonstration of the movement, as well as training tips to ensure proper form and safety.
• Message Board: This is where we see much of the active participation and written discussion within this genre. Novices and experts alike write posts on forums of various CrossFit subject matter. Topics include: methodology for beginners, theory of fitness; crossfit rationale and foundations, exercises, digital coaching, WODs; thoughts on modifications, members personal workout logs, competitions, nutrition, equipment, injuries/health/medical, and how to open a CF gym; tips and guidance.

CrossFit Journal: The CrossFit Journal is self-defined as “a multimedia fitness encyclopedia that can help you improve your performance as an athlete or trainer.” This online magazine, or encyclopedia, contains articles on a variety of topics all relative to the sport of CrossFit. It also has a link to the same message board accessible on the CrossFit.com website. There is a subscription fee for full access to the CrossFit Journal, however plenty of articles are made available to the public free of charge. With a subscription, you not only gain access to the full library of articles, but also may take advantage of instructional videos posted by top coaches, listen to the latest CrossFit news and hear profiles of elite athletes on CrossFit Radio, and interact with other athletes, trainers and leading experts in subscribers-only discussions (http://journal.crossfit.com/subscribe.tpl). Many of the articles can be downloaded as a PDF and printed to share with other crossfit friends and community members. Examples of recent articles include:
• CrossFit basics: Just Squat-“Regardless of what the problem is, the answer is to squat.” Those are the words of CrossFit founder and CEO Greg Glassman. “People who do not know how to squat do not have normal hip function, don’t have normal leg functional,” he says in this medley of clips paying homage to the movement.
• Athletes: Seven Years’ War-“After focusing on competition in 2008, Ben Smith wins the CrossFit Games in 2015. July 26, Ben Smith was crowned the Fittest Man on Earth.”
• Coaching: Master of the Many– “It takes great skill to manage a large group of athletes. Affiliate owners share how they learned to do it and how they’re teaching others to be leaders.”
• Nutrition: The Foundation is Nutrition-“Combining the CrossFit training methodology with a diet of meat and vegetables, nuts and seeds, some fruit, little starch and no sugar brings ‘a jet stream of adaptation,’ says CrossFit founder Greg Glassman.”
• Health: The Myth of Adrenal Failure “Did you overwork your adrenal glands or are you getting worked by mythology and marketing?”

Affiliate Websites: Each Affiliate gym has their own website, a means for participation and communication with local members. On the website, information can be found regarding general introductory information about CrossFit, class schedules and services offered, pricing details, coaches’ qualifications, photos of gym members, a newsletter with current events or fun facts, and of course, a blog recording each WOD (workout of the day). Much of the general information is set up to be accessible to new potential members, inspiring them to join the CrossFit community. It is also intended to be frequently used and accessed by current community participants. Most members enjoy checking the WOD online ahead of class time to mentally prepare for the upcoming challenges. Many affiliate websites are set up for members to maintain a personal “digital whiteboard” in order to record PR’s and benchmark workout weights and times. This allows for a baseline to work from when they next complete that same workout, and hopefully increase weight or speed each time thereafter.

We can see by analyzing the different genres of the discourse community that each genre is structured to strengthen te levels of expertise for members, and also to encourage participation and community bonding. Though most genres are accessible by nonmembers, the intended purpose for each is generally not directed towards those people. Affiliate websites and CrossFit.com are, in fact, the most absorbable genres to outsiders of the CrossFit community. They purposefully support their ideas with simple terminology, not a specific lexis to be understood by knowledgeable members only. This allows an ease of entrance to the community, as opposed to building barriers much too intimidating to break through. Though Devitt argues that genres function for nonmembers, I would maintain that within the discourse community of CrossFit, members are typically the intended audience. The purpose of genres within this community are to increase dedication and proficiency amongst members.

PROJECT 3: HOW DO COMMUNITIES SHAPE WRITING, OR HOW DOES WRITING SHAPE COMMUNITIES?

facebook_04_cam03_o

John Swales, the author of “The Concept of Discourse Communities” states that a discourse community meets six criteria, community goals, intercommunication mechanisms, communication purpose, genre, lexis, and membership diversity.  Genre, in the field of composition, rhetoric, and discourse communities has a much broader definition than what people typically define genre as. Within the arguably largest discourse community of Facebook, the community often shapes the writing using the common genres that include one’s homepage, news feed, and private or direct messaging.

Kerry Dirk, the author of the article “Navigating Genres”  quotes Carolyn Miller, a professor of technical communication that “a rhetorically sound definition of genre must be centered…on the action it is used to accomplish.”  Genres are like tools to appropriately aid people in specific situations, communities of discourse, and everyday life.

The general purpose of the Facebook community involves the free flow of information sharing.  However, the specific genres within the community hold individual purpose depending on what genre is used.  The purposes that the “homepage” and “news feed” serves the Facebook community are similar but also different.  They are similar in the fact that they both largely function off of the infamous Facebook question, “what’s on your mind?.”  Through this single question sparks limitless global sharing and communication on limitless topics or ideas.   They are also intertwined because whatever one decides to share or post on the news feed will also be posted to their homepage and vice versa, as long as the posting option is set to public.  The differences between the genre is that the homepage is personalized and serves a purpose of social acceptance through personal expression.  One typically constructs their homepage in a way that would be intriguing and socially acceptable in order to increase their number of friends.

Private/Direct Messaging

The private or direct messaging genre serves a purpose defined in and of the genre itself.  People private message information that they only want to convey to the specific respondent.  Private messaging allows the user to communicate using any desired lexis or formality free from public assessment.

 

All communication on Facebook within every genre is mostly informal unless the purpose of a specific page deems otherwise.  An example of a Facebook page that would use formal communication and lexis would include a business that uses social media for advertisement and promotional purposes, in which formality is important in order to get the desired message across.  For all other genres like the news feed, homepage, and even private messaging use generally informal means of communication and a unique lexis.  Examples of lexis  that are specific to the Facebook community include:

-FB  (When referring to the Facebook platform) e.g. “I saw it on FB”

– DM  (Direct Message) e.g. “Just DM me the address”

-Tag  (Notifies specific people of your activity) e.g. “I tagged you in my post, did you see it?”

The other lexis that are widely used but not specific to the Facebook community is a mostly text based lingo, abbreviating words such as oh my God(OMG), laugh out loud(LOL), and talk to you later(TTYL) to name a few.

The genres of Facebook shape the writing of the community in an open and either informal or formal way.  The homepage, news feed, and private messaging genres meet the purpose, values, and beliefs within the Facebook community.  Although, these purposes, values, and beliefs are relative to the individual community member, the genres allow the discourse community to consistently achieve the core community goal of information sharing in a free flow form.

Air Quality & Urban Oil Fields

Source: Southern California air board puts new restrictions on urban oil fields – LA Times

We have seen a spate of complaints about air quality near our urban oil fields here in southern California over the past few years.  This appears related to increased use of hydraulic fracturing methods to free up oil and gas and so increase yields from what have become relatively low production, “exhausted” fields.  I am often amazed to see the lengths production companies have gone to in the hope of camouflaging oil derricks and pipes from the casual observer and how frequently locals are unaware of what is going on in their neighborhoods in the context of oil and gas production.  Apparently that visual hiding hasn’t worked when it comes to offensive odors and air quality.

Our regional Air Quality Resources Board has just passed some additional restrictions on production facilities proximate to residences in the urban cores of the Los Angeles metroplex.  Urban petroleum production in California was already subjected to some of the tightest regulations in the U.S. and these additional emission rules further restrict what can be done by these production facilities.

A report last month from the California Council on Science and Technology does a nice job proving an objective overview of these urban oil fields:

The development of these [urban oil] fields, contemporaneous with the growth of the city [of Los Angeles], has caused conflict for nearly a hundred years.  Though oil production has been declining for years, there have been reports recently suggesting the possibility of additional large-scale oil production enabled by hydraulic fracturing…Although the oil and gas sector contributes a minor percentage of the total air pollution burden in the valley, the concentration of these air contaminants can be much larger near the wells that are a source of emissions.  Exposure to toxic pollutants from production wells depends on how close people are to the wells…The future of oil production in the urban environment, including that enabled by well stimulation, has potential implications for human health…

The Los Angeles Basin is unique in its exceptional natural concentration of oil directly beneath a dense urban population.  In few other places in the world has simultaneous petroleum development and urbanization occurred to such an extent.  Conflicts of oil and city life are not new to Los Angeles, but recent reports suggesting the possibility of additional large-scale oil production enabled by hydraulic fracturing, coupled with the ever increasing encroachment of urbanization on the existing oil fields, lends a particular urgency to the need to understand the public health implications of having millions of people who live, work, play, and learn in close proximity to billions of barrels of crude oil…

Beneath the city of Los Angeles is a deep geological basin with all the components and timing of a nearly ideal petroleum system.  As a consequence, the basin has one of the highest known natural concentrations of crude oil, located directly beneath a modern megacity.  Petroleum has been exploited in Los Angeles since prehistoric times, but more than 90 percent of the known oil was found during a 15-year flurry of exploration in the first half of the twentieth century.  Petroleum development and urbanization have gone hand in hand and been in conflict since the beginning. In spite of intense development, large quantities of recoverable oil probably remain.  Besides known oil, the basin has resource potential in three categories: (1) Relatively small volumes of oil in undiscovered conventional oil fields, (2) Large volumes of additional recoverable oil in existing fields, and (3) The possibility of unconventional “shale oil” resources in Monterey-equivalent source rock systems near the center of the basin.  Extensive development of any of these resources with existing technology would entail conflicts between oil production and the needs of the urban population.  Therefore, technological innovations would probably be required for large-scale additional petroleum development in the Los Angeles Basin.

…and the health risks associated with this mix of people and oil appear to mostly be associated with oil drilling activity in general and not fracking per se (note I have added the bolding for emphasis):

With few exceptions, most of the documented air pollutant emissions of concern from oil and gas development are associated with oil and gas development in general and are not unique to the well stimulation process.  In the Los Angeles Basin, approximately 1.7 million people live, and large numbers of schools, elderly facilities, and daycare facilities are sited, within one mile of an active oil and gas well—and more than 32,000 people live within 100 meters (328 feet) of such wells.  Even where the proportion of the total air pollutant emission inventory directly or indirectly attributable to well stimulation and oil and gas development in general is small, atmospheric concentrations of pollutants near oil and gas production sites can be much larger than basin or regional averages, and can present risks to human health.  Studies from outside of California indicate that community public health risks of exposures to toxic air contaminants (such as benzene and aliphatic hydrocarbons) are most significant within 1⁄2 mile (800 meters or 2,625 feet) from active oil and gas development.  These risks will depend on local conditions and the types of gas and petroleum being produced.  Actual exposures and subsequent health impacts in the Los Angeles Basin may be similar or different, but they have not been measured.

The results of our groundwater risk investigation, based upon available data, indicate
that a small amount of hydraulic fracturing in the Los Angeles Basin has occurred within groundwater with <10,000 mg/L total dissolved solids (TDS) and in close proximity to groundwater with <3,000 mg/L TDS.  This creates a risk of hydraulic fractures extending into or connecting with protected groundwater and creating a possible pathway for human exposures to chemicals in fracturing fluids for those that rely on these water resources.

To be sure, there can be localized problems with oil or gas emissions, but I think it is important to note that we are talking about one of the poorest air quality regions of our country.   The greater LA Basin has traditionally had areas of significant non-attainment for national and state air quality standards.  For example, Los Angeles-Long Beach was #1 in ozone pollution, #3 in year-round particulate matter pollution, and #4 in short-term particle pollution as measured by the American Lung Association (2015).  Even areas such as our home County of Ventura have serious problems with ozone (see the figure below).

Ozone attainment by county in California in 2008. Most of these counties were obviously far from achieving established air quality standards.

Ultimately we have crappy air pollution because we are burning a massive amount of oil and gas.  The big issue here, the major source of toxins in our air, and the 400 pound gorilla in the room is the burning of that oil.  Local oil and gas drilling and the subsequent movement of that extracted product is clearly potentially problematic at the local level (especially if you are one of the 32,000 folks living within 100 m of one of these facilities), but the millions of cars and the hundreds of power plants combusting those materials are the true issue.

Those cars and smokestacks, along with the unintended and by-design systems that encourage them, are the issue.  Lets focus on that.
