Human Factors Engineering Quotes

Still another factor is compatibility with vested interests. This book, like probably every other typed document you have ever read, was typed with a QWERTY keyboard, named for the left-most six letters in its upper row. Unbelievable as it may now sound, that keyboard layout was designed in 1873 as a feat of anti-engineering. It employs a whole series of perverse tricks designed to force typists to type as slowly as possible, such as scattering the commonest letters over all keyboard rows and concentrating them on the left side (where right-handed people have to use their weaker hand). The reason behind all of those seemingly counterproductive features is that the typewriters of 1873 jammed if adjacent keys were struck in quick succession, so that manufacturers had to slow down typists. When improvements in typewriters eliminated the problem of jamming, trials in 1932 with an efficiently laid-out keyboard showed that it would let us double our typing speed and reduce our typing effort by 95 percent. But QWERTY keyboards were solidly entrenched by then. The vested interests of hundreds of millions of QWERTY typists, typing teachers, typewriter and computer salespeople, and manufacturers have crushed all moves toward keyboard efficiency for over 60 years.

Owing to the shape of a bell curve, the education system is geared to the mean. Unfortunately, that kind of education is virtually calculated to bore and alienate gifted minds. But instead of making exceptions where it would do the most good, the educational bureaucracy often prefers not to be bothered. In my case, for example, much of the schooling to which I was subjected was probably worse than nothing. It consisted not of real education, but of repetition and oppressive socialization (entirely superfluous given the dose of oppression I was getting away from school). Had I been left alone, preferably with access to a good library and a minimal amount of high-quality instruction, I would at least have been free to learn without useless distractions and gratuitous indoctrination. But alas, no such luck. Let’s try to break the problem down a bit. The education system […] is committed to a warm and fuzzy but scientifically counterfactual form of egalitarianism which attributes all intellectual differences to environmental factors rather than biology, implying that the so-called 'gifted' are just pampered brats who, unless their parents can afford private schooling, should atone for their undeserved good fortune by staying behind and enriching the classroom environments of less privileged students. This approach may appear admirable, but its effects on our educational and intellectual standards, and all that depends on them, have already proven to be overwhelmingly negative. This clearly betrays an ulterior motive, suggesting that it has more to do with social engineering than education. There is an obvious difference between saying that poor students have all of the human dignity and basic rights of better students, and saying that there are no inherent educationally and socially relevant differences among students. The first statement makes sense, while the second does not. The gifted population accounts for a very large part of the world’s intellectual resources. As such, they can obviously be put to better use than smoothing the ruffled feathers of average or below-average students and their parents by decorating classroom environments which prevent the gifted from learning at their natural pace. The higher we go on the scale of intellectual brilliance – and we’re not necessarily talking just about IQ – the less support is offered by the education system, yet the more likely are conceptual syntheses and grand intellectual achievements of the kind seldom produced by any group of markedly less intelligent people. In some cases, the education system is discouraging or blocking such achievements, and thus cheating humanity of their benefits.

The first step to take is to become aware that love is an art, just as living is an art; if we want to learn how to love we must proceed in the same way we have to proceed if we want to learn any other art, say music, painting, carpentry, or the art of medicine or engineering. What are the necessary steps in learning any art? The process of learning an art can be divided conveniently into two parts: one, the mastery of the theory; the other, the mastery of the practice. If I want to learn the art of medicine, I must first know the facts about the human body, and about various diseases. When I have all this theoretical knowledge, I am by no means competent in the art of medicine. I shall become a master in this art only after a great deal of practice, until eventually the results of my theoretical knowledge and the results of my practice are blended into one — my intuition, the essence of the mastery of any art. But, aside from learning the theory and practice, there is a third factor necessary to becoming a master in any art — the mastery of the art must be a matter of ultimate concern; there must be nothing else in the world more important than the art. This holds true for music, for medicine, for carpentry — and for love. And, maybe, here lies the answer to the question of why people in our culture try so rarely to learn this art, in spite of their obvious failures: in spite of the deep-seated craving for love, almost everything else is considered to be more important than love: success, prestige, money, power — almost all our energy is used for the learning of how to achieve these aims, and almost none to learn the art of loving.

A century ago, historians of technology felt that individual inventors were the main actors that brought about the Industrial Revolution. Such heroic interpretations were discarded in favor of views that emphasized deeper economic and social factors such as institutions, incentives, demand, and factor prices. It seems, however, that the crucial elements were neither brilliant individuals nor the impersonal forces governing the masses, but a small group of at most a few thousand people who formed a creative community based on the exchange of knowledge. Engineers, mechanics, chemists, physicians, and natural philosophers formed circles in which access to knowledge was the primary objective. Paired with the appreciation that such knowledge could be the base of ever-expanding prosperity, these elite networks were indispensable, even if individual members were not. Theories that link education and human capital to technological progress need to stress the importance of these small creative communities jointly with wider phenomena such as literacy rates and universal schooling.

I wish I could answer your question. All I can say is that all of us, humans, witches, bears, are engaged in a war already, although not all of us know it. Whether you find danger on Svalbard or whether you fly off unharmed, you are a recruit, under arms, a soldier." "Well, that seems kinda precipitate. Seems to me a man should have a choice whether to take up arms or not." "We have no more choice in that than in whether or not to be born." "Oh, I like choice, though," he said. "I like choosing the jobs I take and the places I go and the food I eat and the companions I sit and yarn with. Don't you wish for a choice once in a while ?" She considered, and then said, "Perhaps we don't mean the same thing by choice, Mr. Scoresby. Witches own nothing, so we're not interested in preserving value or making profits, and as for the choice between one thing and another, when you live for many hundreds of years, you know that every opportunity will come again. We have different needs. You have to repair your balloon and keep it in good condition, and that takes time and trouble, I see that; but for us to fly, all we have to do is tear off a branch of cloud-pine; any will do, and there are plenty more. We don't feel cold, so we need no warm clothes. We have no means of exchange apart from mutual aid. If a witch needs something, another witch will give it to her. If there is a war to be fought, we don't consider cost one of the factors in deciding whether or not it is right to fight. Nor do we have any notion of honor, as bears do, for instance. An insult to a bear is a deadly thing. To us... inconceivable. How could you insult a witch? What would it matter if you did?" "Well, I'm kinda with you on that. Sticks and stones, I'll break yer bones, but names ain't worth a quarrel. But ma'am, you see my dilemma, I hope. I'm a simple aeronaut, and I'd like to end my days in comfort. Buy a little farm, a few head of cattle, some horses...Nothing grand, you notice. No palace or slaves or heaps of gold. Just the evening wind over the sage, and a ceegar, and a glass of bourbon whiskey. Now the trouble is, that costs money. So I do my flying in exchange for cash, and after every job I send some gold back to the Wells Fargo Bank, and when I've got enough, ma'am, I'm gonna sell this balloon and book me a passage on a steamer to Port Galveston, and I'll never leave the ground again." "There's another difference between us, Mr. Scoresby. A witch would no sooner give up flying than give up breathing. To fly is to be perfectly ourselves." "I see that, ma'am, and I envy you; but I ain't got your sources of satisfaction. Flying is just a job to me, and I'm just a technician. I might as well be adjusting valves in a gas engine or wiring up anbaric circuits. But I chose it, you see. It was my own free choice. Which is why I find this notion of a war I ain't been told nothing about kinda troubling." "lorek Byrnison's quarrel with his king is part of it too," said the witch. "This child is destined to play a part in that." "You speak of destiny," he said, "as if it was fixed. And I ain't sure I like that any more than a war I'm enlisted in without knowing about it. Where's my free will, if you please? And this child seems to me to have more free will than anyone I ever met. Are you telling me that she's just some kind of clockwork toy wound up and set going on a course she can't change?" "We are all subject to the fates. But we must all act as if we are not, or die of despair. There is a curious prophecy about this child: she is destined to bring about the end of destiny. But she must do so without knowing what she is doing, as if it were her nature and not her destiny to do it. If she's told what she must do, it will all fail; death will sweep through all the worlds; it will be the triumph of despair, forever. The universes will all become nothing more than interlocking machines, blind and empty of thought, feeling, life...

Take for example job applications. In the 21st century the decision wherever to hire somebody for a job while increasingly be made by algorithms. We cannot rely on the machines to set the relevant ethical standards, humans will still need to do that, but once we decide on an ethical standard in the job market, that it is wrong to discriminate against blacks or against women for example, we can rely on machines to implement and maintain these standards better than humans. A human manager may know and even agree that is unethical to discriminate against blacks and women but then when a black woman applies for a job the manager subconsciously discriminate against her and decides not to hire her. If we allow a computer to evaluate job applications and program computers to completely ignore race and gender we can be certain that the computer will indeed ignore these factors because computers do not have a subconscious. Of course it won't be easy to write code for evaluating job applications and there is always the danger that the engineers will somehow program their own subconscious biases into the software, yet once we discover such mistakes it would probably be far easier to debug the software than to get rid humans of their racist and misogynist biases.

Separation of function is not to be despised, but neither should it be exalted. Separation is not an unbreakable law, but a convenience for overcoming inadequate human abilities, whether in science or engineering. As D'Arcy Thompson, one of the spiritual fathers of the general systems movement, said: As we analyze a thing into its parts or into its properties, we tend to magnify these, to exaggerate their apparent independence, and to hide from ourselves (at least for a time) the essential integrity and individuality of the composite whole. We divided the body into its organs, the skeleton into its bones, as in very much the same fashion we make a subjective analysis of the mind, according to the teaching of psychology, into component factors: but we know very well that judgement and knowledge, courage or gentleness, love or fear, have no separate existence, but are somehow mere manifestations, or imaginary coefficients, of a most complex integral.10 The

Sharon passed around a handout: "Triangle of Self-Actualization" by Abraham Maslow. The levels of human motivation. It resembled the nutrition triangle put out by the FDA, with five horizontal levels of multiple colors. I vaguely remembered it from my one college psychology course in the 1970's. "Very applicable with refugees," Sharon said. "Maslow theorized that one could not move to a higher level until the prior level was satisfied. The first level, the triangle base, is physiological needs. Like food and water. Until a person has enough to eat and drink, that's all one would be concerned with." I'd never experienced not being able to satisfy my thirst or hunger, but it sounded logical that that would be my only concern in such a situation. For the Lost Boys, just getting enough food and water had been a daily struggle. I wondered what kind of impact being stuck at the bottom level for the last fourteen years would have on a person, especially a child and teen. "The second level is safety and security. Home. A sanctuary. A safe place." Like not being shot at or having lions attack you. They hadn't had much of level two, either. Even Kakuma hadn't been safe. A refugee camp couldn't feel like home. "The third level is social. A sense of belonging." Since they'd been together, they must have felt like they belonged, but perhaps not on a larger scale, having been displaced from home and living in someone else's country. "Once a person has food, shelter, family and friends, they can advance to the fourth level, which is ego. Self-esteem." I'd never thought of those things occurring sequentially, but rather simultaneously, as they did in my life. If I understood correctly, working on their self-esteem had not been a large concern to them, if one at all. That was bound to affect them eventually. In what way remained to be seen. They'd been so preoccupied with survival that issues of self-worth might overwhelm them at first. A sure risk for insecurity and depression. The information was fascinating and insightful, although worrisome in terms of Benson, Lino, and Alepho. It also made me wonder about us middle-and upper-class Americans. We seldom worried about food, except for eating too much, and that was not what Maslow had been referring to. Most of us had homes and safety and friends and family. That could mean we were entirely focused on that fourth level: ego. Our efforts to make ourselves seem strong, smart, rich, and beautiful, or young were our own kind of survival skill. Perhaps advancing directly to the fourth level, when the mind was originally engineered for the challenges of basic survival, was why Prozac and Zoloft, both antidepressants, were two of the biggest-selling drugs in America. "The pinnacle of the triangle," Sharon said, "is the fifth level. Self-actualization. A strong and deeply felt belief that as a person one has value in the world. Contentment with who one is rather than what one has. Secure in ones beliefs. Not needing ego boosts from external factors. Having that sense of well-being that does not depend on the approval of others is commonly called happiness." Happiness, hard to define, yet obvious when present. Most of us struggled our entire lives to achieve it, perhaps what had brought some of us to a mentoring class that night.

We all know that air is the essential and important factor on order to live in the world but have we ever thought about that this air in which we breathe possesses specific matter from a range of the natural as well as human related sources. This particulate matter which is found by the Best Engineering colleges Rajasthan 2017 in air is responsible for all premature deaths across the world. But legislation from the different protection agencies has been credited with significantly reduction in this number along with the amount of particulate manner in the presented atmosphere.

These groups were a new kind of vehicle: a hive or colony of close genetic relatives, which functioned as a unit (e.g., in foraging and fighting) and reproduced as a unit. These are the motorboating sisters in my example, taking advantage of technological innovations and mechanical engineering that had never before existed. It was another transition. Another kind of group began to function as though it were a single organism, and the genes that got to ride around in colonies crushed the genes that couldn’t “get it together” and rode around in the bodies of more selfish and solitary insects. The colonial insects represent just 2 percent of all insect species, but in a short period of time they claimed the best feeding and breeding sites for themselves, pushed their competitors to marginal grounds, and changed most of the Earth’s terrestrial ecosystems (for example, by enabling the evolution of flowering plants, which need pollinators).43 Now they’re the majority, by weight, of all insects on Earth. What about human beings? Since ancient times, people have likened human societies to beehives. But is this just a loose analogy? If you map the queen of the hive onto the queen or king of a city-state, then yes, it’s loose. A hive or colony has no ruler, no boss. The queen is just the ovary. But if we simply ask whether humans went through the same evolutionary process as bees—a major transition from selfish individualism to groupish hives that prosper when they find a way to suppress free riding—then the analogy gets much tighter. Many animals are social: they live in groups, flocks, or herds. But only a few animals have crossed the threshold and become ultrasocial, which means that they live in very large groups that have some internal structure, enabling them to reap the benefits of the division of labor.44 Beehives and ant nests, with their separate castes of soldiers, scouts, and nursery attendants, are examples of ultrasociality, and so are human societies. One of the key features that has helped all the nonhuman ultra-socials to cross over appears to be the need to defend a shared nest. The biologists Bert Hölldobler and E. O. Wilson summarize the recent finding that ultrasociality (also called “eusociality”)45 is found among a few species of shrimp, aphids, thrips, and beetles, as well as among wasps, bees, ants, and termites: In all the known [species that] display the earliest stages of eusociality, their behavior protects a persistent, defensible resource from predators, parasites, or competitors. The resource is invariably a nest plus dependable food within foraging range of the nest inhabitants.46 Hölldobler and Wilson give supporting roles to two other factors: the need to feed offspring over an extended period (which gives an advantage to species that can recruit siblings or males to help out Mom) and intergroup conflict. All three of these factors applied to those first early wasps camped out together in defensible naturally occurring nests (such as holes in trees). From that point on, the most cooperative groups got to keep the best nesting sites, which they then modified in increasingly elaborate ways to make themselves even more productive and more protected. Their descendants include the honeybees we know today, whose hives have been described as “a factory inside a fortress.”47

Virtually all systems contain humans, but engineers are often not taught much about human factors and draw convenient boundaries around the technical components, focusing their attention inside these artificial boundaries.

DevOps and its resulting technical, architectural, and cultural practices represent a convergence of many philosophical and management movements (including): Lean, Theory of Constraints, Toyota production system, resilience engineering, learning organizations, safety culture, Human factors, high-trust management cultures, servant leadership, organizational change management, and Agile methods.

Economist Paul Rosenstein-Rodan has pointed to the “tremble factor” in understanding human motivation. “In the building practices of ancient Rome, when scaffolding was removed from a completed Roman arch, the Roman engineer stood beneath. If the arch came crashing down, he was the first to know. Thus his concern for the quality of the arch was intensely personal, and it is not surprising that so many Roman arches have survived.” Why should investing be any different? Money managers who invested their own assets in parallel with clients would quickly abandon their relative-performance orientation.

Expanding its strategy services, the company started to engage clients in the innovation process. The Simmons failure was partly explained by IDEO’s lack of appreciation for what the client’s manufacturing organization was set up to produce. The behind-closed-doors approach that served the company so well in product innovation services, shielding clients from failures along the way, backfired for strategic innovation services. To do better, IDEO began to hire more people with business degrees to complement the skills of the design, engineering, and human-factors experts. IDEO started to collaborate with clients to help them become better failure practitioners.

P2 - We are well on the way in a number of areas. Both billionaires and big Pharma are getting increasingly interested and money is starting to pour into research because it is clear we can see the light at the end of the tunnel which to investors equates to return on investment. Numerous factors will drive things forward and interest and awareness is increasing rapidly among both scientists, researchers and the general population as well as wealthy philanthropists. The greatest driving force of all is that the baby boomers are aging and this will place increasing demands on healthcare systems. Keep in mind that the average person costs more in medical expenditure in the last year of their life than all the other years put together. Also, the number of workers is declining in most developed countries which means that we need to keep the existing population working and productive as long as possible. Below are a list which are basically all technologies potentially leading to radical life extension with number 5 highlighted which I assume might well be possible in the second half of the century: 1. Biotechnology - e.g stem cell therapies, enhanced autophagy, pharmaceuticals, immunotherapies, etc 2. Nanotechnology - Methods of repairing the body at a cellular and molecular level such as nanobots. 3. Robotics - This could lead to the replacement of increasing numbers of body parts and tends to go hand in hand with AI and whole brain emulation. It can be argued that this is not life extension and that it is a path toward becoming a Cyborg but I don’t share that view because even today we don’t view a quadriplegic as less human if he has four bionic limbs and this will hold true as our technology progresses. 4. Gene Therapies - These could be classified under the first category but I prefer to look at it separately as it could impact the function of the body in very dramatic ways which would suppress genes that negatively impact us and enhance genes which increase our tendency toward longer and healthier lives. 5. Whole brain emulation and mindscaping - This is in effect mind transfer to a non biological host although it could equally apply to uploading the brain to a new biological brain created via tissue engineering this has the drawback that if the original brain continues to exist the second brain would have a separate existence in other words whilst you are identical at the time of upload increasing divergence over time will be inevitable but it means the consciousness could never die provided it is appropriately backed up. So what is the chance of success with any of these? My answer is that in order for us to fail to achieve radical life extension by the middle of the century requires that all of the above technologies must also fail to progress which simply won't happen and considering the current rate of development which is accelerating exponentially and then factoring in that only one or two of the above are needed to achieve life extension (although the end results would differ greatly) frankly I can’t see how we can fail to make enough progress within 10-20 years to add at least 20 to 30 years to current life expectancy from which point progress will rapidly accelerate due to increased funding turning aging at the very least into a manageable albeit a chronic incurable condition until the turn of the 22nd century. We must also factor in that there is also a possibility that we could find a faster route if a few more technologies like CRISPR were to be developed. Were that to happen things could move forward very rapidly. In the short term I'm confident that we will achieve significant positive results within a year or two in research on mice and that the knowledge acquired will then be transferred to humans within around a decade. According to ADG, a dystopian version of the post-aging world like in the film 'In Time' not plausible in the real world: "If you CAREFULLY watch just the first

For a long time I took a purely theological standpoint on the issue, which is actually so fundamental that it can be used as a springboard for any debate – if environment is the operative factor, for example, if man at the outset is both equal and shapeable and the good man can be shaped by engineering his surroundings, hence my parents’ generation’s belief in the state, the education system and politics, hence their desire to reject everything that had been and hence their new truth, which is not found within man’s inner being, in his detached uniqueness, but on the contrary in areas external to his intrinsic self, in the universal and collective, perhaps expressed in its clearest form by Dag Solstad, who has always been the chronicler of his age, in a text from 1969 containing his famous statement “We won’t give the coffee pot wings”: out with spirituality, out with feeling, in with the new materialism, but it never struck them that the same attitude could lie behind the demolition of old parts of town to make way for roads and parking lots, which naturally the intellectual Left opposed, and perhaps it has not been possible to be aware of this until now when the link between the idea of equality and capitalism, the welfare state and liberalism, Marxist materialism and the consumer society is obvious because the biggest equality creator of all is money, it levels all differences, and if your character and your fate are entities that can be shaped, money is the most natural shaper, and this gives rise to the fascinating phenomena whereby crowds of people assert their individuality and originality by shopping in an identical way while those who ushered all this in with their affirmation of equality, their emphasis on material values and belief in change, are now inveighing against their own handiwork, which they believed the enemy created, but like all simple reasoning this is not wholly true either, life is not a mathematical quantity, it has no theory, only practice, and though it is tempting to understand a generation’s radical rethink of society as being based on its view of the relationship between heredity and environment, this temptation is literary and consists more in the pleasure of speculating, that is, of weaving one’s thoughts through the most disparate areas of human activity, than in the pleasure of proclaiming the truth.

system naïvely using word2vec, or something like it, might well observe that John is a word more typical of engineer résumés than Mary. And so, all things being equal, a résumé belonging to John will rank higher in “relevance” than an otherwise identical résumé belonging to Mary. Such examples are more than hypothetical. When one of the clients of Mark J. Girouard, an employment attorney, was vetting a résumé-screening tool from a potential vendor, the audit revealed that one of the two most positively weighted factors in the entire model was the name “Jared.” The client did not purchase the résumé-screening tool—but presumably others have.70

To achieve cost savings and strategic performance while innovating and taking decisions that will have serious consequences, apply the systems thinking approach and a knowledge-based vision. Have a long-term focus and strategic objectives; acknowledge the complexity of an organization; recognise that scaling-up successful strategy requires (hyper)convergence of business objectives, data analytics, human-factors engineering, information and cyber security, regulatory compliance, cutting edge technologies… Understand the process! Enjoy success!

After years of painstaking research, in 2006 Yamanaka and his team discovered that proteins encoded by just four “master genes” could turn back the clock and transform any adult cell back into a stem cell. Just as a stem cell could differentiate itself forward in developmental time into a skin, blood, liver, heart, or any other of the two hundred types of human cells, these Yamanaka factors could revert any skin, blood, liver, or other type of cell back into the equivalent of an embryonic stem cell.

In 2012, Japanese cell biologists Katsuhiko Hayashi and Mitinori Saitou announced they had used the Yamanaka factors to reprogram adult mouse skin cells in a dish into iPS cells. They then added more chemicals to turn these stem cells into egg and sperm progenitor cells, the precursors of eggs and sperm. After they placed the same artificial cells into mouse ovaries, the cells matured into eggs. When they put induced sperm precursor into mouse testes, these cells matured into sperm. These induced eggs and sperm were used for mouse IVF, resulting in perfectly healthy baby mice.
