David Gregg and the History of the Optical Disk

An optical disk is a plastic-coated disk that stores digital data. Tiny pits are etched into the disk surface that is read with a laser scanning the surface. The technology behind the optical disk is the foundation for similar formats including CDs and DVDs. David Gregg The optical disk is an analog video optical disk format. The original format provided full bandwidth composite video and two analog audio tracks (digital audio tracks were added later). The optical disk (commonly known as the laserdisc as trademarked by Pioneer) was replaced in popularity by the introduction of DVD in 1997. David Gregg Speaks on the Invention of the Optical Disk By dumbing down an electron beam to visible wavelengths, modulating it to the standard PWM video frequency, and reducing the power to photoresistive requirements, an e-beam optical videodisk mastering system was practical and commercially available in the late 50s. This simple and practical means of mastering was abandoned by others in favor of more costly and time delaying technology: the laser, the supreme toy of the moment for techies. Impact of David Greggs Patents Digital Versatile Disc or DVD and LaserDisc from PioneerMiniDisc from SonyCompact Disc or CD from Philips the 3M Company List of Patents for Optical Disk Technology A transparent plastic disc is described in the Copending Application Ser. No. 627,701, now U.S. Pat. No. 3,430,966, issued March 4, 1969, in which picture information in the form of video signals is recorded on one or both sides of the disc. The recorded picture information on the disc is intended to be reproduced, for example, through a television receiver, by playing the disc on a turntable and by directing a light beam through the disc, as described in the Copending Application Ser. No. 507,474 now, abandoned, and its continuation-in-part application, now U.S. Pat. No. 3,530,258. The light beam is modulated by the video recordings on the disc, and a pick-up head is provided which responds to the resulting light signals to transform them into corresponding electrical video or picture signals for playback purposes. The present invention is concerned with such a video disc record, and with a duplication process by which a multiplicity of such records may be mass-produced from a master record die. The material of the disc record surface is made such to be appropriate for embossing and to enable, under suitable temperature conditions, a slight force pressing the disc surface against a master die to cause the impressions on the surface of the die to be embossed into the surface of the disc. With such an embossing process, there is no transverse flow of the disc material, as occurs in the usual prior art stamping or molding processes, as are presently being used in the production of phonograph sound records, for example, and by which the actual surface of the record is raised above its melting point. The stamping techniques presently being used in the manufacture of phonograph records are not suitable for the extraordinarily fine microgrooves and patterns required by video frequency recordings of picture information. Such stamping techniques as are presently being used in the production of phonograph sound records require that the master record die be heated to a temperature above the melting point of the vinyl or other plastic material used in the phonograph record. In the prior art phonograph record duplicating process, a biscuit of the vinyl or other plastic material is placed in a stamper, and the heated master record die is brought down onto one or both surfaces of the biscuit. The plastic of the biscuit surface is melted and caused to flow radially into the spaces defined by the impressions on the master die surface. As mentioned above, this stamping technique by present-day standards appears to be unsuited for the extremely fine micro-spiral grooves required for video frequency recordings. As an alternative to the present-day practice, and as will be described, a video disc record blank of laminated transparent plastic construction may be provided, the laminated record having a surface layer of relatively soft transparent plastic of any suitable known type, and which can be readily embossed; and a supporting base of a rigid plastic, such as an acrylic resin or polyvinyl chloride. As a first step in the alternate approach, the laminated disc record blank is heated to a point at which the surface tension of the surface material causes the surface to be smooth and regular. This temperature is the critical temperature at which embossed impressions may be formed on the disc surface, and it is below the melting point of the surface material. The embossing die(s) is(are) heated to a temperature slightly above the critical temperature, and it(they) and the record blank are brought together with slight pressure. As the die(s) and the record blank are brought together, the die(s) is(are) cooled to the aforesaid critical temperature, and its (their) surface impressions are embossed into the surface(s) of the record. Obviously, if two sides are being embossed, two embossing dies are required. The supporting structure would require modification, but such modification is well within the skill of the art. After the disc record has been embossed, as described above, an opaque mask is deposited into the portions of its surface around the resulting embossed micro-grooves. This latter mask may be formed on the disc by using a vacuum deposition technique, as will be described. The aforesaid disc record, when laminated in accordance with the aforesaid alternate approach, is used in order to present the desired surface characteristics for optimum embossing capabilities, and yet so that the record itself may be rugged and suitable for rough usage. The laminated structure of the record comprises reasonably tough and dimensionally stable clear plastic for the main body of the disc; and a plastic material on one or both surfaces of the disc which is most suited for embossing. The combination provides a video record disc that is useful, which can take on the appropriate amount of handling, and which still can be embossed easily and effectively.

Mexico A Unified Spanish Language As A Universal Form Of...

Mexico has a long history that goes back as far as the 11th millennium B.C which was over 10,000 years before the Spanish intruded. Across the land, Meso-America was inhabited by various indigenous groups with over 14 languages been spoken and some of them ae still being spoken such as the Zapotec and the Nawan and Purepecha. Aside from the civilized curriculums that Meso-America developed then exploited by Europeans, Mexico today inherits some of its culture such as the association of indigenous groups with agriculture, combining its diverse traditions with factors of a developed civilization such as a unified Spanish language as a universal form of communication. If we analyze of who look like a typical Mexican, it’s people have diverse physical features as if they belong from continents around the world. In fact, Mexican peoples are a composition of various races. The Mestizos in one hand are Indigenous-Spanish, Mulatto’s, on the other hand, are Indigenous-African de scends. Therefore, the typical Mexican of the 21st century is the person who combines historic roots with today’s globalized norms. In this paper, I will summarize certain events of what I learned about the de-Indianization attempts, the idea of the Cosmic race and the urbanization tragedies that unifies Mexican in the 21st century after the revolution based on Bonfill Batalla’s Mexico’s profound and my CHS 345 class.

Values and Ethics in America Case Study Free Essays

BA 3102 – Summer 2, 2012 Video Case Assignment â€Å"End Game: Values and Ethics in America† 1. The most ethical decision is if she turns left into town and report the accident to the police. Even if she turns herself in and jeopardizes to lose her school-funding grant, she knows she did the right thing and her conscious is clean. We will write a custom essay sample on Values and Ethics in America Case Study or any similar topic only for you Order Now She caused a fatal accident that killed the other driver, which means she must report to the police. If she doesn’t, then her friend should turn her in and help her for the long run. Human moral and ethical values are more important then the award for the school grant and reputation in the company. In the Deckop Chapter article-â€Å"Theoretical Bases for Analyzing the Ethics of a Decision†, it compares the utilitarianism and universalism theories. It states that utilitarianism is regarding â€Å"the greatest good for the greatest number and the ends justify the means†. It’s not ethical to disregard the law and serve the greater good. If she was killed in a deadly car accident, I’m sure she would want someone to report her death to the police who would later notify her loved ones. Running away from an accident is not only unethical, but is also a crime and there is no justification for it. The consequences of fleeing a crime scene is more severe than turning yourself in. â€Å"The pressures of a situation may cause one to apply self-serving biases that while in the short-run appear acceptable, in the long-run result in damage to one’s firm, career or self in terms of staying true to ethical principals and human morals†(Desktop, 2008). I strongly agree with this statement. If she won’t report to the police, and deny what she did, she would be living with her guilt knowing she knew what was the right thing to do, but she made the wrong decision. By knowing she is responsible for someone’s life and didn’t notify anybody, in the long run, it will destroy her emotionally (guilt, depression or even suicide). 2. I think I made the right choice for Julia because either way she would have had to face the consequences. If she turns herself into the police, most likely she would get arrested for drinking and driving. She would possibly lose her school-funding grant that all her students dependent on her. She would also lose her reputation as being a good teacher, but one thing she would be acknowledged for is that she was honest and admitted for her action. However, if she don’t turn herself in, she would have to live on the rest of her life guilty knowing she hided the truth. In the long run the truth will be revealed. Part 3 doesn’t change anything for me, because I knew that the follow-up would be that she would hide the truth in order not to damage her reputation in the school, along with not letting her students down. Running away from reality is always easier then facing the truth and admitting for our wrongdoings. Many companies think they can get away with fraud or unethical decision-making, until they either get caught or they turn themselves in. You need to know where to draw the line between personal responsibility and accountability. 3. My decision in question 1 is more consistent with universalism then utilitarianism because universalism focuses on ethical decision making, assuming the decision-maker is following the right morals and values. For example, Julia should report to the police and turn herself in, just as if her loved ones would like to know if she was in a fatal car accident and who is responsible for her death. Also the universalism theory states that everybody is equal and moral ethics apply to everyone no matter what background or culture you are from. Universal ethics explains which behaviors are right or wrong. These ethical standards apply to everybody worldwide. It’s something that a virtuous person is supposed to adhere to and believe in, just like manners that you learn from home. Most manners are universal, though some vary from culture to culture. As a result, I strongly agree with the universalism decision-making tool. How to cite Values and Ethics in America Case Study, Free Case study samples

History of Christianity in Africa free essay sample

History of Christianity in Africa Europeans nations such as, Britain, France, Portugal, Italy etc. Wanted to expand their territory, spread the ways of their culture and beliefs, find new resources and markets. At that time, Africa seemed like the perfect place to explore. There was not much known about the mysterious continent and this ignited their curiosity. They wanted to know the kind of potential benefits Africa would bring. Since these powerful European nations didnt know what to expect, they sent in explorers like, Gill Manes and Mongo Park.The explorers acted like spies. They went to through many different African actions to find Out, which people were friendly and which werent. Also they were supposed to explore the popular river systems and find what kind of raw materials were sold. They wrote about all their adventures, experiences, the kind of people they have met and the things they see in journals, that were later read by the powerful colonial governments. We will write a custom essay sample on History of Christianity in Africa or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page After the explorers did their part missionaries were sent to Africa.Before the missionaries came to Africa, the religion that was practiced were oral and very traditional. And rulers in African nations were closely linked to religion, rulers were also seen as spiritual leaders. And they are looked up to by the people, for guidance, strength and prosperity. In the early sixteen centuries, Portugal sent in Catholic missionaries to gain the trust of certain African rulers, and convert them. Portugal was hoping that the converted rulers, would trust them and become allies.At first, different African nations were curious about the missionaries, and were only interested in new trading markets but once the missionaries criticized their religious practices, they felt threatened and had many of these missionaries thrown and often killed. During the nineteenth centuries, Christianity started o rise in many African nations. Most of the missionaries, felt that Africa non- Muslim Africans lacked any religious structure. They felt that that their ritual acts were barbaric and believed that it was their duty to bring Christianity, civilize and save the souls of the non believing Africans.They were also hoping to push their own cultural ways on them. For example, the converted Africans had AAA certain dress code and they couldnt dance nor drink. While before they had multiple wives, the now had to limit themselves in monogamous marriage. But in order to do all that they needed the trust of the Africans. They finally found the solution Slavery. They decided to preach against slavery and the slave trade. The slave traders were very powerful and settled. They also had control over the ivory trade. So the missionaries tried press the slave trade by asking for protection fro the British. They were hoping that the slavers would give up that control. There were some advantages the missionaries brought, they introduced formal education to the Africans by opening schools. They started teaching the way of the bible. In order to do that, the missionaries had to learn the local dialects that was spoken. And that they did. The bible in many languages were translated by the missionaries. They opened up clinics, and this helped to lower the death rates. Living conditions were improved and literacy rates increased. Most of the European missionaries worked actively for their government. Sometimes they asked for protection from their government when political conflicts threatens to expose their missions. Missionaries from each European nation worked to convince African rulers to trust them. Most of them tried to exert political control of the unsuspecting African states and rule their kingdoms.

About Sensation, Perception, and Attention

About Sensation, Perception, and Attention Free Online Research Papers Key factors in mental processes and interpreting different experiences deal with sensation, perception, and attention. There is a certain amount of stimuli that each of us can handle before we are unable to perform in a productive manner. We have explored each individual’s limits to auditory stimuli along with the ability to perform in a specific setting. The majority of our team can handle a great deal of stimuli when participating in various activities. There can be noises of every sort, and it will not distract them in what they are in the process of completing or participating in. The ability to multi-task allows us to handle various stimuli at once. It also allows us to handle many tasks we are obligated to uphold throughout our busy lives. On the other side of the spectrum, there are also team members who can only study or complete specific tasks when there is little to no noise. These individuals can only handle a limited amount of stimuli or they will not be able to pe rform at maximum capacity. We will further discuss the different experiences and comfort levels of each team member, and how dividing attention will facilitate or impede our learning abilities. Our team has seemed to have adapted to our environments and have similar ways to dealing with noise going on around us. Take Luz for instance, she grew up in a home where everyone yelled to communicate. When she moved away her household was quieter, and she grew accustomed to living in a more serene environment. She is not able to distinguish different conversations at once and is more comfortable in a quiet environment. Christina’s normal environment has loud noises and she can continue with her activities relatively well with loud noise. Her activities include working while listening to other activities going on around her. At home, she can complete her schoolwork although the children play. Christina can tune out noise and continue to work without allowing herself to be distracted. Nicole was told as a child to keep from being quiet in the house so that her sister would adapt to noises while she was sleeping. She can hold multiple conversations while the television is on, the dog barking, and the children acting as children. Nicole seems to need some noise to sleep whether it is a television, radio, a train moving on the track, or an airplane flying overhead. Catherine also needs noise to complete her tasks. She works in an environment in which there are people taking orders, asking for assistance, and warnings of food coming through. She could be distracted by the quiet of her house. Catherine needs music or the television on to sleep. Towanda needs to concentrate on her tasks. She has to be stress free or only have minimal stress to accomplish her homework. Towanda can listen to multiple conversations and share that information with others. Patricia can multi-task and carry more than one conversation at a time. If she wants to eaves drop on more than one conv ersation, she has to concentrate rather hard. She can handle loud situations but if she is going to comprehend it all she has to concentrate. Dividing attention between people can affect people differently. Some people can multitask several things at a time. Whereas others need the area there in to be quiet, so they do not lose their concentration. As far as team C, the majority of us, have many activities going on at once and the threshold for audio stimuli is very high. However, we also had a team member who preferred their environment to be calm and quiet, this worked well for her and her family. When developing a conversation with someone and not giving him or her one’s undivided attention, you will be missing something he or she tells you even if you are a multi-task kind of a person. In addition, when taking part in a conversation one must make the person one is conversing with feel as they are valued. Undivided attention entails good eye contact, minimal or no distractions, listening to the person speaking and waiting to speak once the person has spoken their part. Undivided attention also goes hand in hand w ith proper interpersonal skills. These skills allow one to properly communicate with others without offending them in any manner. Proper interpersonal skills must also be utilized when giving negative feedback. In order to properly converse and collaborate with others undivided attention and proper interpersonal skills are imperative regardless of one’s tolerance level for stimuli. Not only can dividing attention facilitate or impede the team. It can put so much stress on someone that is not used to experiencing this kind of situation. While we have not had a conference call between the team, I am sure if we do, the team will have a quiet atmosphere for that we want to make sure that we can hear each other and give each other our full attention. While most of the team can handle more than one thing at a time, we need to respect anyone that does not want the distractions. Perception is the process of attaining understanding or awareness of sensory information. Sensory perception problems arise because of several factors such as stress, background noise, medical issues, and the level of interest for the subject matter; all of these items affect cognition and learning of information. The stress level of each team member highly affects the individual’s ability to intake information and retain it. If a team member has, a low tolerance for background noise while trying to take in information this could impede his or her ability to concentrate on the information being discussed. Medical issues such as hearing or sight impairments would definitely have an impact on absorbing information that is discussed. The level of interest for the subject matter would also positively affect or negatively impede the progress of a group assignment. When a person takes away something from a situation in which something entirely different was meant, sensory perception has been misconstrued and alternately interpreted. Many factors could contribute to the misunderstanding of information but attempting to be completely focused could alleviate many misunderstandings. A Learning team has members who may perceive and interpret information differently. However, to work and communicate effectively in a team, the members involved must be able to function together to complete assigned projects. Therefore, learning team members have different needs and recommendation on ground rules. When it deals with accommodating auditory sensation, perceptions and attention when learning during group meetings, especially since the learning team is attending classes online and communicated about class projects via Internet. Prepare ourselves for conference calls when assigned projects are due, and each team member should be well prepared, organized, and minimize or avoid distractions when team meeting is in progress. The team members should take care of all daily needs before the meeting begins to avoid interruptions and to stay attentive, so that he or she can take down accurately notes to understand all the information that was shared during the team meetings. Duri ng the learning team meetings, the work environment or area a person is conducting his or her meeting through conference call should be quiet, without the sounds of music television, family disturbance, or ringing sounds of another phone. Each member should be able to give his or her undivided attention, so he or she can hear all barriers communication given as well as avoid distracting other members involved. Another way team members can communicate is through instant messaging; considering some team members have many background sounds going at once in their homes. The conversation one has through instant message can also serve as notes for an assignment. This way to track a dialogue will allow team members to keep a log of conversations offline or although they are away from a personal computer. Another major ground rule is that team members must also be flexible and understanding toward others lifestyles and obligations. It is imperative that we communicate properly in order for the learning team meeting to be productive. We all have many obligations that must be fulfilled throughout our day therefore; we have to accommodate one another. At one point or another, we will have an issue come up that will not allow our auditory sensation, perception, and attention to be used to the best of their ability. We do not all have the same schedules and availabilities therefore we must always exerc ise flexibility. However, during team meetings all members will be respectful and identify superior communication skills by listening and allowing all members to share thoughts and ideas, and hear what each member has to say without interruptions. The learning team will listen and pay attention to each team member’s needs, differences, strengths, and weaknesses to provide appropriate feedback in a positive tone when needed. Effective communication along with effective listening will allow team members to produce better quality assignments. It is inevitable for a group of people to disagree on certain subjects but professionals will disagree in a tasteful manner. Great communication skills allow team members to give constructive criticism as well as receive the constructive criticism. Therefore, at the end of all team meetings conference calls or forum discussions the team leader would summarize all information discussed, so that all members understand the topics discussed, and the plans, and g oals of the whole learning team. However, each team member involvement and understanding the team projects will result in a successful and positive manner as well as the team effective communication skills will be noticeable. In conclusion, we all have different learning abilities and are able to work better with or without noise. The majority of us are used to different activities surrounding us while participating in schoolwork, work projects, and our simple everyday duties. We know how adapt to different environments to achieve what we need to. We also have respect for one another to the fact that if in a group conversation or conference call that we will give our undivided attention as well as keep a noise free environment. Each of us understand the stress levels that we have and are able to work around if needed. All of us are great communicators and are able to achieve the goals that we need to regardless of the situation that we are in.

Suicide Recognizing Symptoms and Helping

Suicide Recognizing Symptoms and Helping Mental Health Issues. Suicide Suicide is the act of intentionally killing yourself. Today, it is the second leading death cause among college students. According to statistics, 10% of college students have had suicidal thoughts or even have been making plans to take away their own lives. Most students, who manifest such thoughts and intentions, suffer from mental illnesses (most often depression), experience frustrations, worries, fears, and doubts. Even though many students can experience these symptoms without thoughts of death, its necessary to prevent or timely notice the frightening moment, when they decide to end their lives. Recognizing The Signs Even though suicide often seems to be a sudden act, its possible to notice the warning signals beforehand and timely help the person. These symptoms arent always clear, but they may include:Extreme level of hopelessness Depression and persistent negative mood Sudden change in behavior and character Avoidance of social activities Abrupt calmness after a long-term depression Talks of death and suicideMost college students who commit suicide suffer from a diagnosable and treatable mental disorder, such as severe depression, anxiety, or negative thoughts after a loss of a loved one. How to Notice Suicidal Behavior in Your Friend? Suicidal students often talk to their peers and express their thoughts. Therefore, you need to be attentive to those you communicate with. See if they manifest such signs as:Talks about their death suicide Threats of hurting oneself Frequent risky behaviors Withdrawal from friends, school, and social activities Depressive behavior and hopelessness Unwillingness to move on after a break-up Talks about the desire to relieve their pain forever Seeing any of these signs, be very careful. Patiently talk with this person and encourage him to get professional help. In case you suspect that your friend, peer, or roommate is suicidal but doesnt want to communicate, consult your campus healthcare providers right away. In emergency cases, call 911 or urgent care facilities. By expressing your concern in time, you might save this persons life. How Do You Know If You Are Suicidal? Be attentive not only to those around you but also to yourself. See if you manifest any of the following behaviors:Withdrawal from your friends and activities you enjoyed before Thoughts or talks about death and suicide Persistent feelings of worthlessness or hopelessness Depressive thoughts Relentless feelings of guilt Strong anger or anxiety Drug or alcohol abuseIf you have any of these signs, seek professional help. Share your thoughts with your friend or family member and ask them to accompany you to the specialist. Suicide Prevention Resources If you want to know how to deal with suicidal thoughts in yourself or your friend, you can ask help from your campus health center or any of these organizations:Active Minds contributes to the effective communication about mental wellness on college campuses, teaches how to prevent mental issues in students, and provides multiple services for those in crisis National Alliance on Mental Illness aims to enhance the lives of individuals who suffer from mental ailments, provides information on suicide prevention, and offers social support groups, 24-hour lifeline crisis chat, and text support line American Foundation for Suicide Prevention aims to provide education, support, and innovative research findings to prevent suicide National Suicide Prevention Lifeline is reachable through a toll-free number 1-800-273-TALK (8255); provides emotional support and assist family members and friends in risk prevention (all talks are confidential) The Trevor Project provides LGBTQ individuals with required emotional support and secure space to have a conversation, offers several channels for help and communication (their toll-free lifeline number 1-866-488-7386 works 24/7)Suicide is a serious issue. Nevertheless, you can prevent this tragedy if you dont nurture your negative thoughts and rather seek ways to deal with them. Remember that your life is the most precious thing you have. Value it.

Increasing Participation in the Marriage Enrichment Group at Essay

Increasing Participation in the Marriage Enrichment Group at Tabernacle Church - Essay Example As communicated to the researcher by the founding pastor, the Tabernacle discovered earlier in its ministry that in a dynamic world, the process of ministry is as important and as critical as the product of ministry. Therefore, small groups became the process through which quality care of members took place. Small groups were also places where members developed personal relationships. However, over the years, the groups at Tabernacle have been reduced to four. The structure of the Tabernacle Church is hierarchical, with the senior pastor being the Chief Executive Officer. Three assistant pastors help the senior pastor in providing general care for the congregation. They are also responsible for leading Men and Women’s Ministries as well as the Marriage Enrichment Ministry. The church has an administrator, a deacon and elder, two praise and worship leaders and an audio technician. Additionally, the Executive Board of the church comprises of the senior pastor, assistant pastors, the head deacon, an elder and the administrator. The Executive Board is responsible for hiring, buying and selling properties on behalf of the church. However, the senior pastor has the final say in decision-making and all of the above leaders report to him directly. The senior pastor of Tabernacle Church communicated to the researcher his observation of an ongoing pattern of low program activity, resulting in low program participation in the marriage subunit; hence, the problem. Further observation with the senior pastor reveals the effectiveness of the marriage enrichment subunit, which is supposed to create a network of support to encourage couples to grow in intimacy and commitment, as well as learn skills that will improve their marriages, has significantly declined. Consequently, the needed leadership is not being provided for the subunit of the family services

Engineering design - Assignment Example This is a crucial step in the design process since it will give aguideof achieving the design’s goals. Questionnaires as a research methodology were chosen for this case. It emerged a suitable method because sufficiently large amount of information can be collected from a large group and within a short span of time as well as in a cost effective way. The data obtained from this method could also be easily and more scientifically analysed (Ketchent.et.al, 1996). To minimize any risk of harm to the user, it was decided that the kettle should have a shield just below the handle. This prevents any burns due to steam from boiling water/tea. In addition, all the electrical components should not be exposed nor get in contact with the water. The inside of the kettle will be made of thick plastic and the outside a coating of polished stainless steel. This ensures a good strength to avoid any physical damage. As stated, this kettle has two heatersthat may work independently, and this will increase the life of the coils. This mechanism consists of the initial starting ‘on’ ‘off’ switch and a thermostat controlled switching. Some old kettles do not have an automatic shut-off mechanism, which requires the user to switch it off when the water has boiled. After brainstorming and analysis of other various switching mechanisms, two possible switching designs were selected and they are outlined below. These concepts were chosen to meet the customers requirements as well as follow engineering specifications as outlined previously. This mechanism involves theuse of a bimetallic thermostat, which is integrated into the element unit usually at the bottom. It consists of a disc bonded together and areusually of two different metals where one expands faster than the other does. When the hot water reaches the boiling point, the produced steam hits this thermostat making it flex in theopposite direction thus disconnecting the contacts cutting off the electric current

Control Systems and Quality Management in Relation to Motivation Essay

Control Systems and Quality Management in Relation to Motivation - Essay Example Most healthcare organizations have established continuous quality control and improvement systems for an excellent and constant quality management program as suggested by Shortell and Kaluzny (1997). Healthcare companies should consider that institutions with constant quality control systems desire to adopt positive changes in all aspects of the organization’s activities. Quality management in healthcare companies offers a framework for service delivery and helps hospitals organize their operation to provide quality services. Â  Management control systems aim at bringing commonness of goals and coordination of processes in healthcare organizations for dysfunctional control systems. The control systems are expected to monitor and regulate the behavior of workers in the organization. For instance, the top management depends on information provided at different management levels to make decisions and to evaluate processes. Management control systems in healthcare organizations are concerned with resource allocation, coordination, and motivation of the employees. The control system in the management of healthcare organizations applies techniques such as total quality management. Total quality management is an aspect of management which constantly aims at enhancing quality services and management. Every healthcare organization’s management should develop a control system customized to its goals and resources. These control systems relate to the motivation of employees in healthcare organizations throug h different principles as outlined below: Â  Focus on critical points: for instance, controls are used where failure is a threat and the costs do not exceed a specific amount.

Arguments on Artificial Intelligence

Arguments on Artificial Intelligence We live in an extraordinary time. Improvements in technology seem to be accelerating at an unbelievable rate. Every time they think Moores Law has reached its limits, tech companies come up with a new level of capability. No less is the advancement of artificial intelligence (AI). Our every day lives are already deeply immersed in AI, and we dont even know it. It controls much of the financial markets, performs law enforcement tasks, and makes our internet searches more useful. Most AI today is weak AI, designed to perform a very specific task (Tegmark, n.d.). But the goal of all research and corporate investment is always more; what else can we know or do? Often, these entities are creating things in a vacuum, with limited moral, ethical, or legal boundaries. When is it too much? The driving force that makes us want to always explore further is what makes the development and use of artificial intelligence (AI) a risky course of action. Why is this a risky course of action? Because giving control of systems to artificial intelligence could have seriously negative results. Take, for example, researchers working with the University of Pittsburgh Medical Center. In this case, they develop a neural network that returns suggestions for treatment of pneumonia patients. Using a historical database with the solutions and results of methods of treatment, the AI is supposed to provide suggested solutions to treat patients. In one solution, it recommended that certain high risk patients be sent home (Bornstein, 2016). This solution had high probability of resulting in death. When working with and complex task, accomplished by human or machine, the law of unintended consequences must always be considered. No matter how well someone thinks they have thought a system through, it is nearly impossible to consider every possible outcome. Certainly, unintended consequences are not all bad, many drugs have side effects that are beneficial and completely not what the drugs was designed to do. On the other hand, many drugs have very negative side effects. Certainly, they are not intended to cause any adverse symptoms, but many have severe unintended consequences, including death. Some would argue, AI is currently in use and benefits everyone with no negative effects. Singularity cannot happen. While we certainly use some types of AI currently and have had minimal negative effects. It is also true we have not reached singularity. It is the height of hubris to believe that we have total control over anything or that we have considered all possibilities. Consider Fukishima or Chernobyl, all possibilities were not covered and resulted in huge disasters. Even NASA, the standard for careful scrutiny of complex systems and procedures has had some catastrophic failures in the form of space shuttle crashes due to hubris of the organization and/or individuals. How many people died on the Titanic? A ship that was unsinkable was sunk by a simple iceberg, or was it hubris? The shoddy steel used in the construction of the hull, the poorly designed bulkheads that didnt reach to the top deck, and the pressure to go as fast as it could are what sunk the ship. And not enough life boats on the unsinkable ship killed the passengers. Hubris lead them down the path to destruction. We are at the point that we have the capability to combine AI to create autonomous military machines. Some are even in the testing phase of development. Machines that make decisions of life and death on their own (Russell, 2015). Absent human intervention, what is to keep one of these machines from deciding the wrong person is a target. A machine knows no morality, no ethical code, only its programming, its goal or reason to exist. Given a powerful enough computational system, it could decide to use everything at its disposal to achieve its goals (Anderson, 2017). Things like taking control of infrastructure, or even humans. So, what do we do? Is there risk? Even captains of industry and experts like Gates, Musk, and Hawking suggest there is (Holley, 2015). It is clear we are already on the path to creating ever more complex and capable AI. We must recognize that we all make mistakes and constantly be on guard against mistakes and, more importantly, hubris. Most expansion of knowledge has risk. When confronted with a discipline that has catastrophic possibilities, we must fight the desire to run forward as fast as we can with no concern for the consequences. Methodical deliberation is the only course. We must consider the ramifications of each step and ensure safeguards are in place should we need to terminate or isolate any AI that develops goals counter to those of humans. If we manage to be conscientious enough and adhere to ethical principles, we might, just might, keep from developing the instrument of our own demise. References Anderson, J. (2017, February 16).

Chaucer :: essays research papers

Although we can see some changes in types of characters, people today are relatively the same as they were during the Middle Ages. Some Chaucerian characters, such as the Parson, the Summoner, or even the Doctor, can relate characteristically to modern-day characters. When compared with the Chaucerian Doctor, the stereotypical, modern-day witch doctor relates similarly. With few exceptions, such as types of clothing, the Doctor and witch doctor are different The brightly colored, expensively made clothes (ll. 449-450) would be substituted for dark, black, flowing robes. The Doctor’s eyes full of strength and intellect. The witch, full of power and demon possession. Despite their differences, their likeness of their actions are greatly similar. They both make magic charms and effigies(l. 428) with their demon possessed hands. They create potions and supposed "magical" elixirs, manifested from cited chants passed down from other generations. They are perfect practicing physicians(l. 432), given that they know the cause of every malady and infliction the body can withstand(ll. 429,430). They appear to many as one to provide an extended hand to anyone in need. But there is a price to be paid for their services, and their eyes cannot oversee the wealth that is due to them. The Doctor then is the same as a witch doctor now, with their appearances different, but their intentions and thoughts the same. Stereotypes are seen only in the imagination. And it is in the imagination from which a television evangelist is characteristically similar to Geoffrey Chaucer’s Summoner. The evangelist is a deceiver to many. He quotes scripture of Biblical content, to put forth an act or display that he might appear unto others as a "man of God." The Summoner is much the same. When he is drunks, he babbles relentlessly of common Latin phrases that he had memorized from the Church services(ll. 655-659). The Summoner has been referred to be "as hot and lecherous as a sparrow(l. 640)," giving new meaning to the purpose of many great evangelists’ falling out from the ministry. Their reasons are those of lust and adultery. Both are deceivers of men in that they appear to be to many as being righteous men. It is only on the inside that reveals the evidence of deception. "Let God be true, and every man a liar." A tree can be determined by the fruit that it bears. The Parson, according to Chaucer, is that tree of which bears much fruit.
