The Dirty Dozen

The company I work for is very big on human factors, as we all have to go through training for it when we first get hired on. And one specific part of human factors they focus on is the aviation "Dirty Dozen". I bring this up because it is a large part of what the Safety Management System (SMS) uses when investigating an aircraft maintenance damage incident. The aviation Dirty Dozen are: fatigue, stress, complacency, communication, awareness, distraction, lack of knowledge, teamwork, lack of resources, pressure, lack of assertiveness, and norms (The Dirty Dozen, n.d.). I have been involved in an incident (or two) myself, and when I talked to the SMS investigator, they literally went down the list of the Dirty Dozen and asked me if I had any issues with any of the conditions. They understand that the employees are human, and are prone to conditions that cause mistakes. I'm not saying that the Dirty Dozen is a fail-safe excuse for an incident, but it gives the investigator the human factor condition(s) that might have played a role, instead of just blaming the employee for the aircraft incident. This allows the investigator to make a fully informed decision on what the proper course of action is following the incident. I have seen thousands of dollars in aircraft damage and good mechanics be reprimanded from verbally to termination.

Human Factors in Aviation Maintenance Dirty Dozen

...Dirty Dozen Twelve of the most common human factors that are related to aircraft accidents or incidents are called the Dirty Dozen. These factors have been identified to affect people and make them to make the poor decisions. The concept of the Dirty Dozen was created in 1993 by Gordon Dupont, he was working for Transport Canada during this time, while he was creating a training program on human factors in aviation. It is now recognized as the foundation of the aviation industries human factor in aviation maintenance. (Adams, 2009) Lack of communication This is one of the more important parts of the Dirty Dozen. Communications are a two way street that has to do with the person who is giving the communications to the person receiving the communications. During verbal instruction it is common the as little as 30% of a message is received. It is safe practice to keep important messages written down so there is not a lack of communications. Some maintenance outfits use log books so that other shifts can refer back to what was done and by who. Verbal messages need to be relatively short with key things being emphasized on. As a person that is getting instructions it is very important no to assume anything and to have things clarified. (Adams, 2009) Distraction Distractions are anything that can take the attention of a person during a task. There are distraction during work that cannot be removed and heave to be worked with. Noises are a key...

...One of the early MRM training programmes, developed by Gordon Dupont for Transport Canada, introduced "The Dirty Dozen", which are 12 potential problem human factors areas. A series of posters have been produced, one for each of these headings, giving a few examples of good practices which ought to be adopted, or "safety nets". These are summarised as follows: 1. Lack of communication Use logbooks, worksheets, etc to communicate and remove doubt. Discuss work to be done or what has been completed. Never assume anything. 2. Complacency Train yourself to expect to find a fault. Never sign for anything you didn't do [or see done]. 3. Lack of knowledge Get training on type. Use up-to-date manuals. Ask a technical representative or someone who knows. 4. Distraction Always finish the job or unfasten the connection. Mark the uncompleted work. Lockwire where possible or use torqueseal.

Scene Analysis Paper

...When Your Life’s in the Toilet A person is highly influenced by those around them. Everyone always seems to find a niche and stick with the people in that environment, whether it is a good one or not. Danny Boyle’s 1996 film Trainspotting is a story about a man who is trying to quit drugs, specifically heroin, but is stuck with the wrong crowd of people. His mind in constantly in an acid trip and the film shows us what he sees. The scene in the public bathroom in particular stands out and shows the struggles faced by Mark and his need to get clean through a great narrative style, great Mis-en-Scene, and finally sound; all of which carefully reflects what the character is feeling. The scene is set up directly after the opening of the film where the main character, Mark Renton gives a long dialogue and sets out to find one last hit, or drug use, before quitting heroin cold turkey. He is sorely disappointed when his dealer does not give him heroin, but instead sells him opiate suppositories. As he is walking back home, the opiate suppositories have a severe laxative effect and Mark has to run into a public toilet, known as “the worst toilet in Scotland,” to relieve himself. The words “the worst……in Scotland” are non-diegetic; they are not originally on the door. He goes to the bathroom and does his business but then realizes the drugs he put in his rectum had not dissolved and are now in the toilet. His severe need for drugs is shown when he does not hesitate to reach into...

Human Factors

...difficulty in sleeping and an increase in fatigue, as well as digestive problems. Longer-term signs of stress include susceptibility to infections, increased use of stimulants and self-medication, absence from work, illness and depression. It is important to recognise the early signs of stress and to determine whether it is acute or chronic. Coping with daily demands at work can be achieved with simple breathing and relaxation techniques. However, perhaps more effective is having channels of communication readily available through which to discuss the issue and help to rationalise perceptions. It is entirely appropriate that some of these channels involve social interaction with peers. As with fatigue, sleep, diet and exercise are all important factors in helping to reduce stress and build resilience to stressors. If the stress is chronic, then...

An Analysis of Social Class in the United States

...Anabell Abud Professor Armstead SYG 2000 Social Class Paper 20 March 2013 An Analysis of Social Class in the United States As we all explore the outside world, we all see the same traffic, stores, supermarkets, restaurants, and shopping malls. There is just one difference, we all live differently according to social class. The social stratification is a system of structured social inequality. It can be described as one lady going to Macys with her credit card wasting $1,000.00 dollars in merchandise and the other woman going to a store of discounts in clothing with a strict budget of $20.00 paying in cash. Another way I see how there are inequalities in our society is a simple question, can you afford to go buy a Michael Kors bag? If you can’t, then the Payless store it is to buy a look-a-like that can hopefully give strangers the impression that you’re not in the poverty sector. Those that are part of the super-rich see the poor as lazy; they deserve to be with meager needs because they haven’t shown merit to escape the poverty class, and the underprivileged that they have to pay out of their tax dollars to support them. Sociologists say we need the poor it’s good for our economy out of many various reasons that most of society doesn’t realize. At least journalist B. Ehrenreich saw what it was to not make it in America as an experiment to educate us all in the jobs of the working class from the article “Nickel and Dimed.” I know I became well aware of these differences...

Jim Brown Research Paper

...on a high note, running for 1544 yards, having 17 rushing touchdowns, catching 34 passes (with four of them resulting in scores), and receiving his third MVP award at the end of his final season (Belson). Eventually, Brown had the goal of transitioning from his NFL career to earning more wealth (Belson). Accordingly, during and after his professional NFL career, Jim Brown was involved in acting and had roles in many renowned films, including the successful movie The Dirty Dozen, which depicted a black man resilient in the face of victimization by the white world (“Jim Brown”). In fact, the reason he unexpectedly retired from football was because production delays for the movie Dirty Dozen conflicted with his football training camp. In an interview with Sports Illustrated, he explained his decision, citing a desire for mental stimulation beyond football and the opportunity to focus on other interests, while also expressing regret but no sorrow for leaving. After his NFL retirement and the success of the Dirty Dozen, Jim Brown continued to pursue acting in the 1960s, earning major roles in movies like Dark of the Sun, Ice Station Zebra, and 100 Rifles. a.

Although SARS’ precise origin isn’t definitively known, all current data points to small mammals know as civets as the most plausible source of human transmission. The outbreak of SARs started in November of 2002 in the Mainland Chinese Province known as Guangdong, where the civets were viewed as a delicacy. In a misguided attempt prevent panic, the Chinese government failed to inform the World Health Organization of the initial outbreak for nearly four months. Subsequently the virus was contracted by 8098 people between November 2002 and June 2003. 774 of these cases proved fatal worldwide. (Trivedi, 2013) The 3 primary factors that enabled SARS to spread so far and so fast were a lack of early reporting by Chinese officials, lack its high virulence, and international flight paths. Early awareness of SARS was severely by attempts at secrecy within the Chinese government in an attempt to prevent panic. This secrecy delayed awareness reaching both the WHO and healthcare staff, who were unaware of SARS virulence and potency. As mentioned, the SARS outbreak originated in the Guangdong Province in China. SARS was easily spread to healthcare staff who in-turn infected their friends, family, colleagues, and other patients. Also, family members would sick patients, and then transport...

Education

...Education Education is so multifaceted that it is difficult for me to know where to begin discussing it, or how to prioritize the many factors. Relaying my own experience is easy: I had a standard classroom approach, supplemented by inordinate reading. In only the briefest and least memorable instances did I receive any individual tutoring. Education is commonly thought of as the job of schools. Adults cry "educate our children!" Everyone has opinions about the best way to do the job. It is of urgent importance, and all the numerous factors are much studied, debated, and new (or old) ideas continually tested or retested. Some people say "it's as simple as . . . " and then name their pet peeve or passion. My view is not of an education specialist, but of one who loves sharing what I learn, and owes much to educators. Since I don't have an educational theory neatly worked-out, nor an outline of my perceptions, my intent is to address each educational ingredient that comes to my mind. After I've said what I think about each topic, readers may have a fair comprehension of my philosophy. First comes sensitivity. If a person be insensitive, be it from numbing cold, exhaustion, drugs, genetic makeup, or upbringing, then the process of education is bogged down, and results come only after great efforts. Sensitivity in my integrated meaning is broad, covering literally the senses, so that deaf and blind people are less sensitive, as well as people whose senses work perfectly...

Data Capture

...AS Level Module 2 Information: Management and Manipulation Lecture One 11.1 Data Capture Lecturer: Deepak Gautam Email: gautamd@wolverhamptoncollege.ac.uk Room: 120, Wulfrun Campus Telephone: 01902 821133 Overview of Data Capture The process of collecting data in a form suitable for use in an information system is termed data capture. For example, before an electricity board can charge a customer for the use of electricity, the customer’s meter must be read and recorded, or captured, on a suitable form. The data must then be transferred into the computer system by means of an input device appropriate to the method of data capture. Sometimes the data capture form is directly readable by an input device, as, for example, in the case of mark sensitive forms which can be read by optical mark readers (OMRs). On other occasions, the data on the form must be first transferred to a suitable medium by a data entry person using a key-to-storage device. Sometimes the data to be captured is pre-recorded on an item to be sold, as with bar codes, so that a data recording form is not required at all, but in many instances, some sort of data capture form is required. The design of such forms is of great importance, since the clearer and more concise the form, the less chance there is of inaccurate data being recorded. Frequently it is necessary to use questionnaires or observation sheets to collect data for statistical...

Enviroment

...Chinese cities estimates the number of people dying prematurely from air pollution is close to three times that killed by traffic accidents. The air has been classified as hazardous to human health, at its worst hitting pollution levels 25 times that considered safe in the US. The entire city is blanketed in a thick grey smog that smells of coal and stings the eyes, leading to official warnings to stay inside. The majority of the air pollution in China is generated by the burning of coal to generate electric power.  China gets 80 percent of electricity and 70 percent its total energy from coal, much of it polluting high-sulphur coal. Around six million tons of coal is burned everyday to power factories, heat homes and cook meals. Jerry Goodell wrote in Natural History magazine: “In China coal is everywhere. It’s piled up on sidewalks, pressed into bricks, and stacked neat the back doors of homes. It’s stockpiled into small mountains in open fields, and carted around behinds bicycles and wheezing locomotives. Plumes of coal smoke rise from rusty stacks on every urban horizon. Soot covers every windowsill and ruins the collar of every white shirt. The Chinese burn less coal per capita than America does but in sheer tonnage, they burn twice as much.” It is relatively plentiful and cheap but very dirty. Many places in China smell like high-sulfur coal and leaded gasoline. The underground coal fires are consuming 20 to 30 million tons of coal a year, pumping tons of ash, carbon dioxide...

When Salaries Arent a Secret

...Five years ago, his company had bought out a stodgy, 20-year-old retailer of women’s apparel, and Hank had come in to run the place. He renamed it and repositioned it, giving it a hip, edgy style. (Get Your Clothes Half Off was the latest slogan, with a racy ad campaign to match). He invested in rapid growth: RightNow! today had stores in 28 states, with more on the way. Last year, Hank had hired a dozen or so tech-savvy 20-somethings and charged them with creating a killer Web site. Launched just last month, the site was already winning awards and generating substantial business. He’d heard that even the folks in corporate were impressed. But oh, those 20-somethings. One in particular: Treece McDavitt. Hank had noticed her—you could hardly miss the elaborate tattoos and double eyebrow rings—but he hadn’t really known her name. Until yesterday. “We think it was Treece,” Charlie Herald had told him. “It was her last day, and this was her parting shot. Not that we could pin anything on her—she covered her tracks pretty well.” Charlie, RightNow!’s VP of human resources, recounted the story as best as he...

Customer Service

...Customer relations final. 1. Service breakdowns and recovery. Service breakdown is the situation when customers have expectations of a certain type or level of service that are not met by a service provider. Those situations can happen anywhere whether the customer is at the store, a restaurant, or a hotel. I am a server and the service breakdown is inevitable. It has happened to me before and usually it is not done purposely. The restaurant I work at offers their customers discounts in form of coupons. Some customers present their coupon once they are seated, when I am responsible for holding on to it and applying it to their check towards the end of their visit. I have forgotten to apply the discount to customers check before and once they have noticed they would question me. I would immediately apologize and make sure that they do get the discount. That’s where the service recovery comes in the picture. The customer service representative is obligated to apologize to the customer and fix the problem immediately, so the customer gets to enjoy their visit, and so their high expectations can be met. Dissatisfied customers are people who don’t receive products or services they have been promised. There are several reasons and causes for customer dissatisfaction and one of them is poor service. Fox example, when I am at the mall shopping and walk in one of the department stores it is nice to be greeted and noticed. If I am looking at jewelry and I am interested in buying...

Burning emits toxic gases that harm the atmosphere and increase the level of VOCs in the air while landfills hold them indefinitely as part of the plastic waste problem throughout the globe. * Plastic Bag Litter * Even when citizens try to manage their plastic bag disposal wind plays a role in carrying them away as litter. This litter is not biodegradable and thus where it lands it tends to stay for long period of time. A bag that is eventually ripped to shreds from high winds or other factors doesn't disappear but instead is spread in smaller amounts throughout the area. This can cause more problems as these smaller pieces are carried away through storm drains and often end up in the waterways. * Plastic bag litter is often also the result of human laziness. The plastic bag might make for a good carry on to the beach for the day but once all of the pretzels and chips are consumed an estimated one in three consumers simply allow the bag to disappear into the wind and waves....
