Scheduling Essay Example

Scheduling Essay Example Scheduling Essay Scheduling Essay 1 . Why is scheduling fairly simple for repetitive systems but fairly complex for Job shops? Scheduling for repetitive systems is fairly simple because the activities and equipment used is the same. This goes for high-volume and medium volume systems because the productions are the similar. Scheduling for Job shops is more difficult because the products formed are customized or of a personal nature and therefore are not mass produced. Stevenson, William J. Operations Management, 1 lth Edition. McGraw-Hill Learning Solutions, 2011. VitalBook file. 5. Briefly describe each of these priority rules: FCFS First come first serve; it is processing Jobs in the order they are received at the work station or machine. SPT Shortest processing time; processing the shortest processing time Job EDD- Earliest Due Date; andling the Job that has the earliest due date. SIO- Global rule ; Final due dates for orders rather than intermediate, departmental deadlines. RUSH- Local or global rule processing Jobs on an emergency basis Stevenson, William J. Operations Management, 1 lth Edition. McGraw-Hill Learning Solutions, 2011. VitalBook file. 7. What problems not generally found in manufacturing systems do service systems present in terms of scheduling the use of resources? Customer requirements in service systems generally present very different circumstances than those encountered in manufacturing systems. Some services can use appointments and reservations for scheduling purposes, although not all systems are amenable to this. When multiple resources are involved, the task of balancing the system can be fairly complex. Stevenson, William J. Operations Management, 1 lth Edition. McGraw-Hill Learning Solutions, 2011. VitalBook file. 8. Explain forward and backward schedulings and each ones advantage. Forward scheduling : Scheduling ahead from a point in time. Forward scheduling is used if the issue is How long will it take to complete this Job? Forward scheduling enables the scheduler to determine the earliest possible completion time for each Job and, hus, the amount of lateness or the amount of slack can be determined. Backward scheduling: Scheduling backward from a due date. Backward scheduling would be used if the issue is When is the latest the Job can be started and still be completed by the due date? With backward scheduling the scheduler is able to determine if the due date can be met. Stevenson, William J. Operations Management, 1 lth Edition. References: Stevenson, William J.

Mosquito Control With Birds and Other Natural Predators

Mosquito Control With Birds and Other Natural Predators When the topic of  mosquito control is discussed, thrown into the mix is usually a fervent argument for installing purple martin houses and bat houses. Stores that cater to bird enthusiasts often tout the purple martin houses as the best solution for keeping your yard mosquito free. Bats, which may not be the most beloved of mammals, are defended with the claim that they consume hundreds of mosquitoes per hour. The truth of the matter is that neither purple martins nor bats provide any significant measure of mosquito control. While both eat mosquitoes, the insect makes up a very tiny portion of their diets. Other animals might have an upper hand on mosquito control, particularly in the fish, other insect, and amphibian classes. Mosquito Munchies For bats and birds, mosquitoes are more like a passing snack. Multiple studies of wild bats have consistently shown that mosquitoes consist of less than 1 percent of their diet. In purple martins, the percentage of mosquitoes in their diet is slightly higher- about 3 percent, at most. The reason is simple. The payoff is small. A bird or a bat that feeds on insects must invest considerable energy in flying around and must catch the bugs in mid-air. Birds and bats are usually seeking the biggest caloric bang for their buck. Given the choice between a mosquito morsel, a hardy beetle, or a mouthful of moth, the mosquito hardly makes the top-10 list. An Efficient Mosquito Natural Predator Gambusia affinis, also known as the mosquitofish, is an American fish that is utilized by some mosquito control districts across the country as a very effective predator of mosquito larvae. As far as natural predators go, the mosquitofish is by far the most efficient natural predator of mosquitoes. The mosquitofish is a voracious predator. In certain studies, mosquitofish have been shown to consume up to 167 percent of their body weight in invertebrate prey, including mosquito larvae, per day. Mosquitofish, as well as small predatory fish such as guppies, can be quite useful in the reduction of mosquito larvae given the right conditions. Other Mosquito Consumers The closely related  dragonflies and damselflies  are natural predators of mosquitoes but do not consume enough mosquitoes to cause a significant impact on the wild mosquito population. Dragonflies are often referred to as mosquito hawks for an unsubstantiated claim of being able to kill thousands of mosquitoes. One thing that does make the dragonfly a better predator than most is that, in the aquatic larval stage, one of their food sources is mosquito larvae. Dragonfly larvae can sometimes live up to six years in this stage. During this phase of life, dragonflies do the most damage to mosquito populations. Frogs, toads, and their young tadpoles are often touted as excellent for mosquito control. In reality, while they do consume their fair share, it is not enough to seriously put a dent in vast mosquito populations. When frogs and toads do consume mosquitoes, it is usually after they have transformed from tadpole to adult.

The Strategic Threats Facing Google Research Paper

The Strategic Threats Facing Google - Research Paper Example Moreover, the firm was far ahead of other search engines because their search results were of high quality, and due to this, the company has become very popular and successful. Besides being so popular, the firm employs several people globally; moreover, it has always been ranked as one of the best firms to work for. The firm has acquired several firms to enable it to continue being innovative. In the year 2003, it acquired Applied Semantics Inc, which advanced the advertising campaign of the firm. In the year 2006, Google acquired Writely, and as the end of 2006 approached, it acquired YouTube by outbidding other competitors for $1.65 billion. Similarly, early in the year 2007, the firm at $3.1 billion acquired Double click. The firm has acquired several other firms since then; one of them is Tonic Systems. The mission statement of the firm, which is to sort out the worlds’ information, makes it available and helpful to its users; moreover, this statement refers to their goals; however, it is not reflecting how the firm is supposed to earn profits and revenue. Moreover, the mission statement of the firm does not provide a timeline but it just states the end-result. However, the mission statement of Google is very original and distinctive and very relevant, thus, it should not be altered. Google is an internet search engine. It enables individuals to get information that is kept in several other sites. The main product or service of Google is internet search; it also enables individuals using the internet to search for single words or word combinations. Other than being a search engine, Google also advertises the products and services of other firms, which is also another source of revenues. Besides, Google has a number of online productivity tools and some of them include Gmail, which is a free webmail and Google voice talk. The major source of  revenue for Google is its advertising services, AdSense, as well as AdWords. Advertising contributes to 99% of the total revenues of the firm; in this case, firms make payment to Google to put their AdWords on Google sites as well as in its affiliates.

Challenging perspective in research - Essay Example According to him: â€Å"Looking at the different cultures of the world, one finds that no society is classless that is un-stratified. There are some primitive communities so small that no class strata appear, the social organization resting almost entirely on age, sex and kinship; but even here chieftainship individual prowess and clan or family properly introduce an incipient stratification.† (Davis and Moore, 1945: 242, quoted in Zaidi, 1997: 29) A child learns the process of interaction with other individuals from family and the peer group. All the parents try to bring up their children within the best possible atmosphere. The resources play pivotal role in the socialization of the individuals in a society. The members belonging to the upper class contain better opportunities to educate and nurture their children, and thus can make them more civilized and cultured ones in the future years to come, whereas the lower classes lack proper sources and opportunities that may influence their children. Rothstein has also defined the fact in the following words: â€Å"Parents of different social classes often have different child-rearing styles. It makes sense when you think about it: If upper-middle-class parents have jobs where they are expected to collaborate with fellow employees or create new solutions to problems, they are more likely to talk to their children in open-ended ways that differ from how parents address children if their own jobs simply require following orders. Children raised by middle-class parents will, on average, have more inquisitive attitudes toward academic material than children raised by working- class parents. No matter how competent a schoolteacher, lower-class children’s achievement will, on average, almost inevitably be less. Because the achievement gap already exists by age 3, it is unlikely to be narrowed without expensive infant and toddler centers where lower-class children can be

Library Statement of Goals Essay Example for Free

Library Statement of Goals Essay I have submitted my application for admission into the Kent State School of Library and Information Science as an avenue for professional growth within my current career. As a former Spanish teacher and currently a computer technology teacher, it is important to pursue the MLIS as current librarians seek retirement and technology continues to infiltrate libraries across our nation. I am currently interested in pursuing the MLIS plus the K-12 licensure in order to serve in an urban school library setting. My current teaching assignment of computer technology lends itself to a smooth transition from the classroom to a librarian position as our school district places more emphasis on digital media. I remain fully committed to providing instruction to students; however, with teachers and school librarians retiring in droves, I fear that our schools will be left with overworked teachers and no librarians in our schools. By completing the MLIS degree, I will be accomplishing an additional career objective. I remain committed to my career goals that were previously established many years ago. My first goal was accomplished by completing my undergraduate course of study at the University of Cincinnati. My second career goal was to obtain my M. Ed. In School Administration and I accomplished that particular goal in the year 2000. My third goal, albeit somewhat personal, was to earn my private pilot’s license, and I successfully completed that task in 2001. My fourth career oriented goal was to transition from teaching Spanish to teaching computer science with an ultimate goal of finishing the required courses to earn the MLIS degree. I am currently in the middle of this goal. After speaking to our retiring librarian, she suggested that I apply my technology expertise and apply for the vacant school librarian position. Our current librarian highly encouraged me to seek at least the minimum courses for K-12 certification. After speaking with Dr. Sarah Harper and educating myself about the MLIS program and learning about the additional career opportunities associated with the MLIS, I have decided to pursue this additional graduate degree. The role of the librarian appears to be shifting from the traditional aspects of managing a library to more of the role as a librarian media technologist. An important current issue of the library is to also serve as a digital media center due to the increased technology needs facing libraries. I am greatly interested in this transition as many school librarians almost double as the digital media technologist. Colleges and universities are also adopting the model of librarian media technologist to enhance the needs of such educational institutions. As our digital technology library needs grow, I foresee a point where the current traditional school librarian could potentially be at a slight disadvantage without minimal technology background. I firmly support digital media; however, print media is equally as important. It will be the role of the librarian to determine which media shall remain in print edition for students, and which media will transition to digital media. Another current issue that is important is to fully integrate the school library as an extension of the classroom. It is important to fully utilize the library beyond the common routine of â€Å"pulling books† for a specific course. Instead, it would be beneficial to teachers and students if the library were to be established as an academic department. Establishing meaningful collaboration between the library personnel and teachers will foster a learning environment conducive to learning. As a school librarian, a goal should be to create a library setting that embeds the role of the library into the classrooms. Instead of thinking of the library as an independent space of a school, the library now serves as an extension of the classroom. However, it is equally important to keep in mind, the school librarian is not able to provide content specific instruction, but rather, instruction on how to locate the resources required for the specific content. It is important for the librarian to serve as an instructional partner in the learning process. Finally, another current issue that I believe is important is increasing the mobility of the library. Technology has advanced to where it is no longer required to leave the house and go to the library to seek and acquire information. With nearly all of our students owning a mobile device, whether it is a cellular telephone, iPad, Nook, mobile devices are changing the way information is delivered and accessed. While students easily have access to the internet through mobile devices, it is equally important that students have access to digital records housed in the library. Furthermore, many library users have learned the convenience of downloadable e-books. As teachers, students, and others navigate away from the traditional book delivered in print, it will be important for the librarian to explore new ideas and collaboratively implement a plan to cost effectively deliver more data via mobile devices.

Billy Budd :: essays research papers

As portrayed in the Bible, Adam and Eve were the perfect human species. This was only a result because of their complete innocence. God let them remain in his presence because of this reason. After the devil conned them into eating fruit from the Tree of Good and Evil they became unclean. In Herman Melville’s Billy Budd the question this apparent: Is innocence and ignorance dominant over knowledge and power? To emphasize the importance of this theme, Melville uses the character Billy Budd. Aboard the ship, the Rights-of-Man, Billy is a cynosure among his shipmates. He also becomes a leader by setting an example by his innocent ways. He is later transferred to the Indomitable. After waving goodbye to his shipmates, he salutes the ship saying "And good-by to you too, old Rights-of-Man" (11). Many witnessed this event to be ungrateful to the Indomitable and his role as a member of this ship. While aboard the Indomitable, Billy meets up with John Claggart, the master-at- arms. Claggart’s personality coincides with that of Billy’s and with the help from Dansker, Billy soon realizes. Billy soon realizes that Claggart is out to get him after he talks to the Dansker. "The old man†¦ rubbing the long slant scar at the point where it entered the thin hair, laconically said, Baby Budd, Jemmy Legs is down on you" (34). This surprised Billy, because the master-at-arms had been nothing but, what seemed to be, nice to him. Throughout the story, Billy witnesses incidents and threats made by Claggart on other members of the ship. This is just the start of tension between Claggart and Billy. "Starry" Vere, the captain of the ship, is a man who believes the military duty of one’s life must rise above the moral values. And everything must be done in a procedure manner. This contrasted Billy’s way of life in which he remains pure and quiet about the mutiny aboard ship. After much turmoil, Claggart decides to approa ch Captain Vere about Billy, accusing him of conspiring to mutiny. Captain Vere is overwhelmed by this information and does not believe what he is hearing. However, to keep things fair and under control he schedules a conference between the three. After hearing the amazing propaganda that Claggart has presented, Billy becomes speechless and strikes Claggart in the head killing him instantly. Captain Vere tries to keep military law before morals and decides to hold a trial in which persuades the jury to sentence Billy to death.

Human Resource Information System Essay

The function of human resources (HR) departments is generally administrative and common to all organizations. Organizations may have formalized selection, evaluation, and payroll processes. Efficient and effective management of â€Å"Human Capital† progressed to an increasingly imperative and complex process. The HR function consists of tracking existing employee data which traditionally includes personal histories, skills, capabilities, accomplishments and salary. To reduce the manual workload of these administrative activities, organizations began to electronically automate many of these processes by introducing specialized human resource management systems. HR executives rely on internal or external IT professionals to develop and maintain an integrated HRMS. Before the client–server architecture evolved in the late 1980s, many HR automation processes were relegated to mainframe computers that could handle large amounts of data transactions. In consequence of the high capital investment necessary to buy or program proprietary software, these internally developed HRMS were limited to organizations that possessed a large amount of capital. Raija and Hlonen (2009) described the role of information systems in the process of combining district organizations which use information system in financial administration, HRM and social welfare. They explored the role of IS in decision-making in public sector. The lack of inter-opera ability between legacy systems and new information systems was perceived as a huge problem. In the present situation of our economy, most of the companies used manual system in their company, also some are using computerized system which lessen the expenses and saves time. An effective and well-designed Human Resource Information System shall make it easier to manage record, update files and retrieve records in Employee records. Confidentially, accuracy and integrity are maintained. The use of computer enables user to minimize efforts to do a certain job or action nowadays. When the Information Technology emerged, it gave a great impact when it comes to business problems especially when it comes to data entry accuracy, managing data’s and retrievals. Dr. Karishna & Meena (2010) identified the various functional areas to which ICT is deployed for information administration in Higher Education institutions. Current level of usage indicates a clear integration of ICT for managerial or information based administration in higher education institutes. Matthew &Douglas (2009) analyzed that nature of developing IS in any organization is characterized by multi dimensional and often messy problems, involving technical organizations and personal dimensions. David et al(2010) analyzed the main traits of efficient firms and the main sources of firm’s efficiency through samples of catalan firms. Firms efficiency shows a significant improvement when advanced ICT uses are combined with human resource practices, Dileep (2010) indicate that HRIS is an integration of HRM and information systems. HRIs helps HR managers perform HR functions in a more effective and systematic way using technology. HRIs system usually a part of the organization’s larger management information system which would include accounting, production and marketing functions. Ikhlas & Zaid (2010) indicate that the quick response and access to information were the main benefits of HRIS implementation. They also identified the cultural and financial barriers to the implementation of HRIS. Kristine & David (2010) identified the implementations or upgradation of HRIS has been undertaken with the aim of utilizing HRM functions.. Barriers also associated with the acceptance of new or upgraded HRIS.HRIS play an important role in shaping user perception and behavior. The addition of information technology to the human resource industry has revolutionized the contemporary workplace. HR professionals now have an increased capacity not only to gather information, but also to store and retrieve it in a timely and effective manner. This has not only increased the efficiency of the organization but also the effectiveness of management functions. New technology has also created opportunities for higher levels of stress for younger and older workers alike (Mujtaba, Afza, and Habib, N. (2011), unethical temptations and behaviors (Mujtaba, 2011), and opportunities for better leadership practices (Mujtaba and Afza, 2011). After delivering our suggestions for the Customer Appreciation Program, Kudler has asked us to evaluate the Human Resource Department, to see what changes need to made, to make the process better and smoother. Before making suggestions, we have to analyze their current setup. The Human Resources Department is a valuable department, so we want to assure that Kudler’s is running smoothly and efficiently. Kudler’s current HR Department is setup in the following manner: they use Quick Books and outsourced their payroll to Intuit. Intuit tracks all the following information for each employee. They track the employee’s personal information, pay rate, tax exemptions, hire date, seniority date, and organizational information. Changes to any of this information, can only be change by submitting a special form in writing by the employee’s supervisor and entered by the accounting clerk. The accounting clerk also keeps a file with the appropriate tax forms for each employee and all changes to employee data. The employees turn in manual time sheets weekly, which are approved by the store manager. The time sheets are then faxed to accounting, where they are entered for payroll. All changes have to be approved by the direct supervisor and store manager. Each store manager is responsible for keeping the files of their employees. They are kept in a locked file and include the following information: job application or resume, performance reviews, I-9 forms, and any disciplinary memos or performance management issues. The managers are also responsible for tracking any time off, which includes vacations.
