I visited my “Motherland” once; (July 30, 2009)

 

I read Ulysses once; it was all ancient Greek.

All languages are suitable for writing poems:

Poems are meant to express the spirit of the Land;

Long before languages were created or codified.

Samuel Butler demonstrated that Ulysses was written by a woman,

A young woman and single; I like that better;

It is more convincing.

 

Butler confirmed that Ulysses’ trip was around Sicily.

Seven years to tour Sicily is irrelevant.

Years in ancient times were measured by seasons.

The shorter year was winter; the longer one was the extended long dry season.

 

One systematic mind split the differences in moon rotations.

Another mathematical mind worshiped number three.

His enemy preferred the symmetrical number four.

Years kept shifting in length.

 

It was a time of confusion and rare standards.

It was a time of total freedom for ignorance

Mainly for the “free men”.

Slaves were redundant and obeyed the will of their masters.

They still do on a larger scales, number and ignominy.

The masters are mostly regrouped in “Secret Clubs” of free men;

Sometimes in veto power nations around a United Nation.

 

I visited my “Motherland” once.

I returned to my City-State of Itaca once.

I had no Penelope there waiting for me:

I would never care for a dumb witch waiting for a war man.

I have never been a war man: I fled the war zone for reasons.

 

I visited my “Motherland” once.

I visited my “Motherland” with my new family.

I called up my exiled friends to join me.

I didn’t care to face little men and little souls;

Petrified and perched on mountain peaks.

I toured my motherland solely with my family like a tourist:

Nature and natural phenomena are romantic and truer to my origins.

 

The children loved my motherland;

They had plenty of fun with super energetic and fun children.

They climbed trees, jumped walls and cliffs.

They played war battles with sticks;

On land, seas, and around the galaxies.

Fire crackers a go-go; makeshift guns and swords flailing around.

Many wounds and scars to mend;

Barely missing their folks; the tamed ones.

It was a dangerous habit experiencing natural chaos among the kids’ world.

I won’t allow my children this extravagant climate;

They won’t visit my motherland as long as in my protection.

 

I visited my “Motherland” once.

I fled as quickly as the airport was re-opened.

I boarded the ships of my adoptive nation;

Evacuating its citizens from a worn torn dysfunctional society.

 

I visited my “Motherland” once.

Nobody cared to ask me about my life in my “adoptive” society.

They blabbered about stories and anecdotes of the dead and mostly the dying.

They recounted of newer generations, totally irrelevant to me.

Nobody cared to ask how much I suffered and struggled to survive.

Everybody mocked the caring soul who ventured to know the new me.

 

I visited my “Motherland” once.

I am currently living in a standardized society,

Highly organized and administered for just the free people:

A society every bit the dream of racist Plato in his Republic.

 

I visited with trepidation:

I had been given a medal of honor in my adoptive society.

I kept on my high white horse and barely mingled.

They insisted on raising me on shoulders and necks.

I lamely fought this uncalled for barbaric show of substituted glory.

Another medal of honor was attached on my lapel.

The officials never cared to investigate if I was proud of my origin.

I was a sample of men worthy of the motherland’s origin.

 

 

I visited my “Motherland” once.

I visited with hesitation; I am back almost broke financially.

A life of learning and struggles is irrelevant.

I kept my silence, wrapped in mysteries.

I created my own island.

With inexistent public transportations

It is so easy and comfortable creating islands;

Alongside islands of communities.

I returned for good to my island.

 

Many poets toured the world for inspirations.

They returned to keep silent.

The world was too gruesome to laud humanity;

Miserable beings were no inspirations for chants and songs.

Pablo Neruda was also frustrated and lived in solitude abroad.

He clawed to his roots, the toiling and brave workers.

His “Canto general” was a culmination of the spirit recounting its origins;

Of dirt, mud, forests, rivers, sand, wind, wilderness, and the survival of man.

Neruda returned to chant the dignity of South Americana.

 

All languages are suitable for writing poems and the best ones.

It is the spirit of the Land that chants through the soul.

No need to be ashamed of traditions and customs;

All civilizations had almost similar traditions and customs.

Cultures that banished theirs for the sake of modernity

Are not bearable communities for the living.

Cultures that banished theirs for the sake of modernity

Transferred them to exclusive clubs, secretive associations,

The guardians of the customs and traditions

To rule, govern, and safeguard the continuity of the “Free elected Men”

Article 41

“What do Human Factors measure?”: An example of warning alarm systems

This article is an ongoing project.  The dependent variables or performance measurements adopted by Human Factors/Ergonomics are varied and should be judiciously selected to correspond to the tasks, systems, methods, and purposes they are researching.

The professionals in the field of human factors, depending on their primary discipline and interest, consider appropriate performance measurements for the types of controlled experiments, evaluation, or testing methods.  The studies  either answer practical problems that cannot be resolved by the traditional methods that analyze systems’ feasibility and performance or are oriented toward basic research.

The dependent variables should be necessarily directly related, or highly correlated with the essential human factors performance criteria, of mainly reducing errors in the operations, safe usage of products/systems, and health concerns of workers and end users.

Many of these measurements and their corresponding techniques and procedures were initially developed by psychologists, who were attuned to the practical facets of their discipline, and how their research can be applied to engineering design of interfaces between target users and systems that are increasing in complexity and becoming essential in running the functioning of our daily lives.

For example, I asked my class to participate in resolving a problem.  We were to evaluate two warning alarms used in factories and to decide which product to select.  I asked them what could be the potential, valid, and effective dependent variables for this evaluation.

Obviously, the first answer was to measure how loud the alarm is:  this variable would not do because alarms are designed to be loud in order to alert workers and employees, but the data on how many of them heard the alarm goes off will certainly not provide a decisive choice among the mostly loud systems. Loud is not a performance criteria in alarm systems but an engineering objective.

The next step was to make the students think about the real purpose of having a warning alarm.  Obviously, warning alarms are produced to warn against the existence of fumes, the starting of fire, a serious danger, or a drill.  Suppose you were conducting a drill, then what might you be interested to observe and record?

At this junction, ideas started to fuse from every corner;: the noise of the alarm should be jarring and very uncomfortable to the ears, visual stimuli should be designed in the product such as in police cars; automatic connections to fire brigades should be contemplated when installing warning alarms; more than one exit door should be opened; emergency exit doors should not be blocked by inventory materials.

Now, where the warning alarm should be installed?  Should it be next to the emergency door because this is the normal direction where heads turn to, or in the opposite direction because the reaction of people is to move in a direction away from the warning noise?

I meant to explain the fundamentals of evaluation methodology and ended up with practical answers, which is fine and encouraging, but we had to get back to methodology and what could be the most appropriate safety measure.

Most probably, how many workers actually vacated the premises on hearing the alarm could be a good starting decision variable.

Better, how many vacated within a standard duration in accordance with safety regulations might be an improved measuring stick.

At this stage there was confusion in discriminating among, controlled experimentation, evaluation, and testing methods, as well as the differences among dependent, independent and control variables.

Obviously, what we were discussing was testing the effectiveness of warning devices, since evaluation is targeted for the packaged deal that includes after sales services, maintenance, repair, instructions manuals, extra commendable features, and so forth.

In addition to rating each specification, evaluation methods might consider comparing end-users behaviors such as like/dislike, acceptance, or rejection depending on psychological preference judgments.

For example, we were supposed to be discussing how to test among warning products, but it was not straightforward to the students.  Students were talking of other factors such as the frequency range of the alarm, whether it is in the lower or upper frequency scale, the timber of the alarm, the loudness range and levels to manipulate, the characteristics of the background noise, the layout of the facility, the type of noises emanating from the machinery and equipments, the outdoor noise level, the characteristics of the workers and their hearing deficiencies, and how the workers were initiated with drills, safety warnings and instructions.

What could be the performance measures for warning products in controlled experimentation?

In this case, the investigator needs first, to select objective, accurate, and reliable measurements such as the increase in heart beats above individual baselines, or the duration needed before the heart beat return to its resting level, or the reaction time for any changes in the dilation of the pupil of the eyes, or other physiological characteristics, which are not highly correlated among themselves, if more than one dependent variables are used, and should be used.

Secondly, the purpose in controlled experimentation is to select the characteristic of sound or noise that best affect the outcome of the study in order to design a performing warning alarm with the purpose of eventually reaching design guidelines for products/systems; and third, that the conditions and location of the experiment have to allow the repeatability of the experiment.

More than one session is necessary to sort out the difficulties and distortions in the untrained experimental minds. However, we agreed that in testing the warning alarms we need to control important factors that might affect the results such that we need to test all the selected warning alarms in each one of the facilities, in every location that they might be installed, during the day and night shifts, in the morning, after lunch, and at the end of a shift if necessary and funding is available.
