Tidbits and notes posted on FB and Twitter. Part 182

Note: I take notes of books I read and comment on events and edit sentences that fit my style. I pa attention to researched documentaries and serious links I receive. The page is long and growing like crazy, and the sections I post contains a month-old events that are worth refreshing your memory.

Documentary: Nero didn’t burn Rome. He didn’t persecute the Christians. St Peter didn’t die during Nero time. No foreign military expansions were conducted. Nero was an artist and didn’t appreciate the cruelties of the elite senators.  He surrendered himself with ministers from sons of freed slaves and built wonderful achievements. He did assassinate his mother Agrippa for fear of dethroning him. And he did assassinate his ex-wife Octavia.

What taxonomies Human Factors have to conceive?  How about the classification of human errors when operating a system, their frequencies and consequences on the safety of operators and system performance?

One alternative classification of human errors is based on human behavior and the level of comprehension. Mainly, skill-based, or rule-based or knowledge-based behavioral patterns. This taxonomy identifies 13 types of errors and discriminates among the stages and strength of controlled routines in the mind that precipitate the occurrence of an error, whether during execution of a task, omitting steps, changing the order of steps, sequence of steps, timing errors, inadequate analysis or decision-making.

Another taxonomy rely on the theory of information processing and it is a literal transcription of the experimental processes; mainly, observation of a system status, choice of hypothesis, testing of hypothesis, choice of goal, choice of procedure and execution of procedure.  Basically, this taxonomy may answer the problems in the rule-based and knowledge–based behavior.

It is useful to specify in the final steps of taxonomy whether an error is of omission or of commission.  I suggest that the errors of commission be also fine tuned to differentiate among errors of sequence, the kind of sequence, and timing of the execution.

There are alternative strategies for reducing human errors by either training, selection of the appropriate applicants, or redesigning a system to fit the capabilities of end users and/or taking care of his limitations by preventive designs, exclusion designs, and fail-safe designs.

I now take one task at a time. Now that time is worth everything, Time is irrelevant to me. I could be happy.

In my mind, “geek” and “nerd” are related, but capture different dimensions of an intense dedication to a subject. The distinction is that geeks are fans of their subjects, and nerds are practitioners of their fields of interest.

  • geek – An enthusiast of a particular topic or field. Geeks are “collection” oriented, gathering facts and mementos related to their subject of interest. They are obsessed with the newest, coolest, trendiest things that their subject has to offer.
  • nerd – A studious intellectual of a particular topic or field. Nerds are “achievement” oriented, and focus their efforts on acquiring knowledge and skill over trivia and memorabilia.

Then I learned of the double standards since my tacit demotion is that we must keep at work the details of moral standards accepted at work, and never transfer it outside the premises. This attitude is categorized under State Secret interests… Home moral standards are off-limits in the active function.

I am revisiting history; (Apr. 21, 2010)

            History is a collection of stories that need to be revisited frequently; stories to be revised with new eyes and new knowledge.  Human behavior did not change perceptibly; if any, human cruelty to mankind and nature increased by several notches.  Suppose the worst despots of antiquity or even two century ago witnessed the two world wars that afflicted mankind within 30 years and then he watched the news of the dropping of two atomic bombs within a week then, how would he react comparing his atrocities compared to current mankind behaviors?

            In general, history stories are recounted Hollywood style packed with actions, heroes, traitors, smart generals, and foresighted leaders and monarchs.  Sure, the new Anglo-Saxon of Protestants landing in the US killed and massacred far more Indians than the Spanish Conquistadors managed to inflict in Latin America but these behaviors do not account for the disappearance of the Indians in the USA.  It is the slow and steady holocaust strategies applied on the Indians that did the trick. Indians died the slow death from new diseases they were not immune to them; they died the non hero death in more pain and suffering than gunshot wounds. The Indian were first chased out of fertile lands and then even the bison was denied them. As the herd of bisons arrived from the Canadian plains they were slaughtered for their fur by the new white comers. Indians who might have acquired some immunity to white diseases had to die of famine, depression, and loss of all hope in a future for the survival of their descendents. Thus, Indians stopped procreating in this new world of cruelty and blatant discrimination.

            The Moslem Ibn Khaldoun in 15th century North Africa, considered to be the prime sociologist and ethnographer, wrote that when a people lose hope in a better future then they decline procreating; when a people has high hope for their descendents then population increase.  If you revise history stories you can link, with high positive correlation, between periods of luxury and fast and increase in procreation. Once people realize that their sons have high chances to die in successive wars, be maimed or and made prisoners for nothing in return then they refrain from procreating; thus, the Empire starts a slow but steady decline.  Moslem Arab armies with rudimentary arms defeated the two main Empires of Byzantium and Persia within 20 years: thirty years ago, Byzantium and Persia waged non stop wars against one another to recapture a district here and another one there. The two people were already exhausted emotionally to enlisting soldiers and bankrupt economically to hiring mercenaries.

            You might offer a counterpoint: “How come after 70 years of slow and steady holocaust process inflicted by the Zionist movement (Israel State) on the Palestinian people this strategy did not slow the increased procreation of the Palestinians?”  My conjecture is that most Palestinians live in camps: Camp life is too depressing if devoid of kids playing, laughing, and cheering up the camp.  The more kids are playing around the more hope is sustained. Camp creates community supports and discrepancies among classes are not noticeable to prevent sharing the little families have and caring for kids of neighboring families.

What are error taxonomies, and other taxonomies in Human Factors in Engineering?

Article #12, written in April 9, 2005)

May you allow me just a side explanation on experimentation, to set the foundations first?

Psychologists, sociologists and marketing graduates are trained to apply various experimentation methods and not just cause and effect designs.

There are many statistical packages oriented to providing dimensions and models to the set of data dumped into the experiment, so that a preliminary understanding of the system behavior is comprehended qualitatively.

Every applied science has gone through many qualitative models or schema, using various qualitative methods, before attempting to quantify their models.

Many chairmen of engineering departments, especially those who have no understanding of the disciple of Human Factors in engineering and would never touch this body of knowledge and methods with a long pole, ask me to concentrate my courses on the quantitative aspects.

That hint sends immediate shiver through my rebellious spirit and I am tempted to ask them “what taxonomy of methods are you using in teaching engineering courses?”

What taxonomies Human Factors have to conceive?  How about the classification of human errors when operating a system, their frequencies and consequences on the safety of operators and system performance?

Human Factors professionals attempted to establish various error taxonomies, some within a specific context, during their study and analysis of errors that might be committed in the operation of nuclear power plants for example, and other taxonomy that are out of any specific context.

One alternative classification of human errors is based on human behavior and the level of comprehension. Mainly, skill-based, or rule-based or knowledge-based behavioral patterns.

This taxonomy identifies 13 types of errors and discriminates among the stages and strength of controlled routines in the mind that precipitate the occurrence of an error, whether during execution of a task, omitting steps, changing the order of steps, sequence of steps, timing errors, inadequate analysis or decision-making.

With a strong knowledge of the behavior of a system, provided that the mental model is not deficient, applying the rules consistently most of the errors will be concentrated on the level of skill achieved in performing a job.

Another taxonomy rely on the theory of information processing and it is a literal transcription of the experimental processes; mainly, observation of a system status, choice of hypothesis, testing of hypothesis, choice of goal, choice of procedure and execution of procedure.  Basically, this taxonomy may answer the problems in the rule-based and knowledge–based behavior.

It is useful to specify in the final steps of taxonomy whether an error is of omission or of commission.  I suggest that the errors of commission be also fine tuned to differentiate among errors of sequence, the kind of sequence, and timing of the execution.

There are alternative strategies for reducing human errors by either training, selection of the appropriate applicants, or redesigning a system to fit the capabilities of end users and/or taking care of his limitations by preventive designs, exclusion designs, and fail-safe designs.
