The capability to achieve quality work is only as good as the weakest link in the process. Continuous improvement processes are driven from the top, but implemented from the bottom. The problem areas must be prioritized; critical processes must be selected for improvement; and improvement goals must be set for the project team. The problem-solving and implementation is done by teams that include staff at the working level. This is a bottom-up process that requires the involvement and commitment of the staff. Employees are encouraged to report conditions adverse to quality, and they are encouraged to take part in quality improvement teams. The blend of quality management techniques and philosophies noted above is generally referred to as Total Quality Management. Implementing quality improvement programs in the United States revitalized the automobile industry, telecommunications, and numerous other industrial and commercial enterprises. Improving processes reduces waste and rework time; it raises product quality while reducing costs and stimulating productivity. Workers? participation in problem solving and decision-making, while working in quality improvement teams, strongly influences how people think of themselves in the organization and how management views them. Workers have learned that the organization needs their brainpower as well as their brawn. Management learned that the people closest to the process know best how to improve the process when given a chance to participate in how work is accomplished. This teaming together of management and workers to improve organizational processes spilled over into the safety arena as we shall see. Human Factors and Ergonomics Human factors is the name of an engineering profession that focuses on how people interact with tasks, machines or computers, and the environment, with the consideration that humans have limitations and capabilities. Often, human factors will study the human within the system to ensure that we understand the limitations of the human within the current structure, product, or process. Human factors engineers will evaluate human-to-human, human-to-group, or human to-organization interactions to better understand the phenomena associated with these interactions and to develop a framework for evaluation. Simply put, human factors involves working to make the environment function in a way that seems natural to people and attempts to 5-4 Department of Energy Human Performance Handbook Chapter 5 Human Performance Evolution optimize tasks, the machine design, and the environment. Under the banner of safety, the purpose of human factors research and practice is to maximize the safety and healthiness? of work environments and work practices and to ensure the usability of tools, devices, and artifacts in general. A priority in human factors is consideration of users? physical, behavioral, and information-processing characteristics and requirements. Experience has shown that failure to deal with such characteristics can lead to wasted functionality, user frustration, inefficient practices, discomfort, and error-prone activity. In the end, human factors are concerned with providing a good fit? between people and their work or leisure environments. The war marked the development of new and complex machines and weaponry, and these made new demands on operators? cognition. It was observed that fully functional aircraft, flown by the best-trained pilots, still crashed. Army, showed that this so-called pilot error? could be greatly reduced when more logical and differentiable controls replaced confusing designs in airplane cockpits. Chapanis, a founding father of ergonomics, also pioneered the design of the standard telephone touchpad, teleconferencing, safety labels, night vision, digitized speech, and human-computer interaction. Paul Fitts was an American Air Force Colonel who also examined the man-machine interface in aviation. He studied pilot accident records, digging through 460 cases of what were labeled as pilot errors? in 1947. He found that a large part of the cases consisted of pilots confusing the flap and gear handles. Typically, a pilot would land and then raise the gear instead of the flaps, causing the airplane to collapse onto the ground and leaving it with considerable damage. Fitts? examined the hardware in the average cockpit to find that the controls for gear and flaps were often placed next to one another. They looked the same, felt the same, and, which one was on which side was not standardized across cockpits.
His work was complemented by the efforts of project editor Lee Awbrey erectile dysfunction treatment orlando levitra with dapoxetine 40/60mg visa, Blue Lunar Eagle wellbutrin erectile dysfunction treatment order 40/60mg levitra with dapoxetine mastercard, who took on an increasingly engaging role and personality as we brought this book to erectile dysfunction drugs egypt order levitra with dapoxetine 40/60mg on line its final stages. I am especially appreciative for her inspiration to rework the Preface and Chapter One, which I gladly did, and which I feel speak more immediately to the reader of this book. Thank you both, and may the success of this book redound to your consummate care for the truth. Finally I would like to honor and thank my children: Tara, the golden one, my grandson, SamuelJoshua Sheps, andJeff of Engine Company Number Nine in Phoe nix; also Paul Mecklenburg, who has always held the faith in our work, and Heidi Mecklenburg, that her dream of the Unicorn Princess may become true once again. Acknowledgments Time and the Technosphere: the Law of Time in Human Affairs is essentially a pro longed set of meditatipns occasioned by the one most powerful and overwhelming, ~ event of our time, the 9-11, the Inevitable Event of September 11,2001. Subsequent events may overshadow this one in horror and magnitude, but it was this event in particular, the destruction of the World Trade Center towers, that sent a signal that something very profound had occurred to change the way we think of ourselves and our future. In presenting these meditations and reflections in the form of a book, I am pain fully aware of the limitations of this medium in the information age. Keeping in mind that the volume of information has increased five times in the past century with much of that increase occurring only in the past decade-I am very reluctant to put anything down to be published in the form of a book. I was raised well on the writings of Marshall McLuhan and his definitions of media and how they affect our senses. It is altogether obvious that a book in your hand is not the same as reading a text on a computer screen. Of course, the computer has made it possible and easy for virtually anybody and everybody to write a book, and so we encounter one of the great hazards of the information age: the decline in discrimination and the criteria of excellence. These reflections, too, are very much to the point of the grand theme of this text. It should last until the New Time has established a new order of reality on this now anguished Earth. Whether or not destruction and the total collapse of civilization will occur first, we do not really know. Those who are at all familiar with any of my earlier books, will find that Time and the Technosphere is but a continuation of themes that have pro voked me since I first considered literature as a medium of communication. It is important to know where the author is coming from, and how he got to this particu lar point of reflection. In this regard, Time and the Technosphere is the organic result of a lifelong pursuit of a study of the nature of art, time, and history. This study has been woven together by a dialectical process that defines the evolving nature of consciousness. So, for those who are interested, herewith follows a brief literary autobiography, the better to understand my point of view. My earliest book, Charles Henry and the Formation of a PsychophysicalAesthetic (1972), states the grand theme of a holistic science that unifies body and mind, sense and nature, the harmonic pursuit of which has been at the root of all my endeavors. This pursuit was amply demonstrated in my second book, Mandala (1972), which, as a root text of the counterculture, was an artistic, philosophical, and cosmic plea for a harmonic resolu tion to the process of history. It is a sign of the times that Mandala is no longer in print, but instead a book bearing the same title, but which does not even include the original Mandala in its bibliography, is in print with the same publisher. Amnesia is one of the side-effects resulting from information overflow with no discrimination. Unfortunately, cultural amnesia is always accompanied by an increase in trivialization, and thus we arrive at the mediocrity and sensationalism of the present moment. My next book, the Transformative Vision: Reflections on the Nature and History of Human Expression (1975, 1991), took the aesthetic and unitive themes of the first two books to the next stage of my visionary analytical process, elaborating on the mean ing of time, history, and cosmos. In rereading the later chapters of the Transforma tive Vision, I am struck by their prophetic accuracy, as well as their sense of impend ing tragedy. It is hard to believe that only 26 years have gone by since that book was first published and now we are plunged into the maelstrom of what was then thought to be the worst scenario possible. The Transformative Vision also defined human con sciousness as the cerebral-neurological dialectic of psyche (aboriginal, primal intui tive art) and techne (civilizational, rational science), emphasizing that only in their absolute synthesis would there be a harmonic resolution to the problem of history.

To examine the overall impact course rescheduling could have on student achievement zma impotence quality levitra with dapoxetine 40/60mg, we perform two simulations where we assess how achievement would differ if students were assigned sched ules based on their academic aptitude erectile dysfunction penile injections generic 40/60mg levitra with dapoxetine free shipping. The simulations aim to erectile dysfunction frequency age buy levitra with dapoxetine 40/60mg lowest price estimate the extent to which course schedules could be used to equalize student outcomes while raising mean achievement. In total, there are 4,536 student-schedules, representing over 1,900 different combinations of sched ules. Results show a narrowing of the overall grade distribution with no change in average performance across students. Bottom tercile students experience a 2% of a standard deviation increase in overall performance, but a similar loss is predicted for the top tercile. The second simulation allows for heterogeneous effects of schedules based on students? pre dicted ability. Results from the second simulation are shown in Table 9 and show that re-assigning schedules raises expected performance by 1. Middle and top-tercile students experience very slight gains and losses, respectively. Since these students are less affected by course schedule than lower-ability students, being assigned sub-optimal course schedules does not greatly affect their predicted achievement. Discussion and Conclusions the goal of this study was to determine how the organization of classes throughout the school day affects academic achievement for adolescents. To do this, we consider the effects of three distinct components of course schedules: time of day, student fatigue, and teacher fatigue. Two similar students taking the same classes with the same teachers, but with different schedules could be expected to get grades as different as two-tenths of a standard deviation (approximately a grade difference of a B to a B+). Adolescents learn better in the late morning and afternoon? times that are better aligned with their circadian rhythms. Assignment to classes and professors is random, attendance in all classes is mandatory, and all students enrolled in a course in a given semester take the exams during a common testing period and are graded on a collective curve. This research extends our understanding of what outside factors affect academic achievement and provides an opportunity to increase achievement, and, presumably human capital, by rescheduling the times that classes are held. There are several recommended policies, or rules-of-thumbs, administrators or students could 13 follow, based on our results. We also show a clear penalty of consecutive classes, especially for the lowest-performing students. These include factors such as busing and transportation schedules, after-school programs, classroom availability, athletic schedules,? Free periods during the last period of the day are also wasteful? teens learn well in the afternoon and breaks are best used to offset accumulating fatigue. Sports commonly dictate that students have their last period free because of scheduling con? In general, targeting one or two classes per student for optimal timing may be more feasible than restructuring their entire schedule. Unfortunately, our data do not allow us to determine why differences across ability groups exist. There are a number of hypotheses as to what explains this difference (high achieving students may be better able to learn when tired, teach themselves material they missed in class, or are more likely to be morning-oriented individuals), and would be an interesting area for further research within the social or biological sciences. The outcomes for the regressions shown in columns (1) (6) is the normalized grade in the course. The outcome for Column (7) is whether the student earned an A or A in the course while the outcome for Column (8) is whether the student earned a D or F in the course. All regressions include controls for student characteristics and classroom peer effects as well as course by year by schedule-day? A full set of teacher schedule variables are included in all regressions, but not shown because they remain statistically insigni? The second column shows predictions for a student who has one free period, which is assumed to be in the prior period for each estimate. Schedules were assumed to have homogenous impacts across all students using results from Column (5) of Table 4. Schedule impacts were predicted separately by ability tercile using results from Columns (2)-(4) of Table 5.

The Princeton team has chosen a policy of keeping the identity of all experimental subjects anonymous among other reasons erectile dysfunction doctors in richmond va cheap levitra with dapoxetine 40/60mg line, in order to erectile dysfunction diabetes type 2 treatment order levitra with dapoxetine 40/60 mg visa eliminate motivation for subjects to erectile dysfunction drugs at cvs cheap levitra with dapoxetine 40/60mg online cheat. However, the fact that Subject 10 contributed considerably more to the database than any other subject, suggests that this individual was either a member of the experimental team or someone who had become a close friend of the experimenters. As such, Subject 10 might well have had access to information which would make it possible to tamper with the data recording system. According to the researchers, the automated and redundant on-line recording of data preclude data tampering as does the protocol requirement that the printer record be on one continuous, unbroken paper strip. It would appear that all necessary precautions have been taken, short of submitting subjects to constant visual observation. The subjects are submitted to intermittant visual observation which the researchers believe is sufficient to control against tampering with the equipment, given their particular setup. Several other subjects, who participated in fewer experimental trials, actually had scores with greater chance deviations. By analyzing the data from only the first series of 7,500 trials (1,500,000 binary digits) from each subject, it was possible to level the influence that Subject 10 exerted on the database. In this analysis, with each subject carrying an equal weight, the results were significantly beyond chance. The probability 597 experimental series was p < 10-35, whereas 235 control series yielded an overall score well within the range of chance fluctuation. In order to account for the observed experimental results on the basis of selective reporting (assuming no other methodological flaws), it would require "file drawers" full of more than 50,000 unreported studies averaging chance results. To explore the idea of person-unique signatures, Dean Radin, working at Princeton University, used a powerful, new "neural network" computational technique that is proving to be adept at discovering weak patterns in noisy data. Dean Radin Neural networks are a form of parallel processing based upon research about how the brain encodes and processes information. The power of these networks rests upon the discovery that when numerous elementary processing units are richly interconnected under the right conditions, they can automatically learn to associate arbitrarily complex inputs with arbitrarily complex outputs. Information processing in these networks takes place in the interactions among large numbers of artificial neurons. The study involved training a network to associate data with given individuals, then observing whether the trained network could successfully identify these people based upon new data. Two sub-datasets were required for each person: One was used to train the network and the other was used to see whether the 313 trained network could transfer its knowledge to new data. Thus, each series of 50 runs was split in half, using the first half as the training set and the second half as the transfer set. Results showed that these networks were able to learn to associate data with 32 different individuals, then, in statistical terms, successfully transfer that knowledge to new data. The experimental apparatus allows 9000 polystyrene balls to drop through a matrix of 330 pegs, scattering into 19 collecting bins. As the balls enter the bins, exact counts are accumulated photoelectrically, displayed as feedback for the operator and recorded by a computer. Subjects are asked to concentrate on shifting the mean of the developing distribution of balls to the right or left, relative to a concurrently developing baseline distribution. Over three thousand experimental runs have been conducted with twenty five individuals. The Princeton University researchers note that virtually all of the statistically significant results have come from a deviation of the balls to the left of the baseline. This, they claim, cannot be attributed to any known physical assymetry in the system. These effects included clouding of X-ray or photographic film; or pronounced changes in the records of photoelectric tubes, thermoluminescence docimeters, or biological detectors. It should be noted, however, that the quality and reliability of reports of Chinese research is very inconsistent. At least one set of knowledgable observers believes that some reported results resulted from slight-of-hand. One correlation was significant: the correlation with increase in the number of high-amplitude pulses, as the Chinese had reported.
