Acidity The Natural Way Stomach acids are essential for the digestion of food. Increased secretion of acids in the stomach gives rise to acidity. Acidity is manifested by several uncomfortable symptoms such as burning and pain in the chest and stomach; nausea; bitter taste in mouth; vomiting and discomfort in the stomach. Acidity, been one of the commonest digestive complaints. At some point in our lives, we have all suffered from these symptoms. Acidity is generally stimulated by consumption of spicy foods, junk food, carbonated drinks, fried foods, chocolates, stress or lack of sleep. Obesity, pregnancy and other medical conditions may also give rise to acidity. Irrespective of the reason, acidity can prove to be an uncomfortable experience. There are several natural remedies that work wonders in keeping acidity at bay and also in providing relief from acidity. Though, chronic acidity complaints may require proper medications. Some of natural remedies are as follows:- Bananas They prove to be an effective antidote for acidity, as it has a high pH value. More the pH value, lesser are the symptoms of acidity. Banana further, enhances the production of mucous by the stomach lining which reduces the harmful effects of acidity. The high fibre content of banana decreases the recurrence of acidity. Apart from banana, watermelon and cucumbers too are effective against acidity. Consumption of overripe bananas during an attack of acidity is even more beneficial.

It takes a special person to be a Special Educator. In most jobs you are in need of patience, but with this career a requirement is patience. Some people are cut out for this career and some are not.

I have also interviewed a Special Educator and I will discuss how she feels about being†¦show more content†¦The lowest 10% earned about $36,740 and the top 10% earned about $87,390. Special Educators typically have a higher salary than a general education teacher. Work Environment The work environment for a Special Educator is in a public, magnet, private and charter schools. Some can also work in preschools. Many work the traditional 10 month school year with two months off during the summer months. Some may opt to work with special summer programs. It is not uncommon for a Special Educator to work in residential facilities, hospitals and student homes. They also can teach the child’s parents methods and ways to help the child develop skills.

Job Outlook The United States Department of Labor states that â€Å"employment of special education teachers is projected to grow 6 percent from 2012 to 2022, slower than the average for all occupations. However, overall demand will be driven by increasing enrollment and continued need for special education services.† With the advance screening and the identification of different disabilities of children are expected to increase the demand for this career.

Performance of Employees in MNC Malaysia-Free-Samples-Myassignment

Question: Discuss about the Impact of Training and Development on Employee's performance in MNC Malaysia. Answer: Introduction The research is conducted to evaluate the impact created by the training and development sessions on the performances of employees working in various multinational companies in Malaysia. The training and development programs have helped in enhancing the efficiency of recruitment and selection processes and allowed them to perform to their potential as well. (Anitha 2014). In Malaysia, the multinational organisations have provided training and development to workers for promoting growth and development and ensured more productivity, sales and profit generation too. Research aim The researchs major aim is to evaluate the effects created by training and development on the performances of workers of the multinational companies in Malaysia. Research objectives To assess the impact of training and development of the performances of workers of multinational companies in Malaysia To evaluate the most suitable approaches for enhancing the performances of workers To assess the various methods for monitoring the performances of workers within the Malaysian multinational companies To recommend relevant measures for managing training and development sessions and create positive impact on the performances of workers Research questions What impact is created by training and development on the performances of workers of Malaysian multinational companies? How can the training and development enhance the productivity of multinational organisations in Malaysia? What are the different kinds of ways or approaches for monitoring the performances of workers of Malaysian multinational companies? What are the suitable measures recommended for management of training and development and improve workers' performances and organisational productivity? Literature review The most important assets of the company are employees within the multinational companies of Malaysia. The productivity and reputation of employees are dependent upon the performances of employees and it can be managed through proper training and development provided to them (Bello 2012). Definition of key concept Strategic leadership The strategic leadership is an essential aspect that focuses on the ability to influence individuals and allow them to make decisions in an effective manner. This would contribute to the overall success of the organization as well as maintain good financial stability. The strategic leadership provides a direction to ensure proper growth and development of the company. To manage changes, the business executives need proper skills and knowledge to formulate the strategies and implement those for successful business planning (Anitha 2014). To manage changes and ambiguity, strategic leadership is essential for providing a sense of direction to employees as well as develop ownership and alignment within the groups of individuals to manage changes easily (Bashir and Long 2015). Work performances of employees Work performances are needed to be monitored consistently for checking whether the employees have managed to fulfill the requirements and criteria or not to achieve the organisational goals and objectives. In case the employees lacked certain skills, knowledge and expertise, it is the duty of the human resource management department to provide them with training sessions so that their skills and knowledge are improved, and they can work with much more commitment and dedication (Cherian and Jacob 2013). Training and development Training and development sessions can be provided through case studies illustration, classroom lectures, role-playing, simulations as well as computer based training programs (Elnaga and Imran 2013). The multinational companies in Malaysia must assess and identify the training and developmental needs of employees and understand that each of them has different types of needs and preferences, which are needed to be met carefully for progressing in their professional career (Ford 2014). Thus, the training and development are important for both improving the performances of employees and organisational development (Giuliani and Macchi 2013). Training and development could bring several benefits such as enhanced productivity and less supervision required. The employees performances are monitored to identify weaknesses and reduce the turnover of employees, increase consistency, lift up team spirits, enable optimum utilisation of resources and decrease time of learning. The informal training and development can help in learning through feedbacks and enable social interaction between the organisation and employees working there (Jehanzeb, Rasheed and Rasheed 2013). Critical review of Theories and models Contingency theory Thecontingency theoryis an effective theory used within the Malaysian multinational companies for leading the organisation in the right direction and make proper decisions. Here, contingent means dependent and the organization manages its business operations and processes based on the external and internal conditions (Kennett 2013). The leaders apply their own style of leadership in the right situations to assess the environment within which the company operates and ensure delivering good quality products and services to customers. With the help of managerial skills, they can utilize information technology to improve the performances of employees through necessary training and development (Kooij et al. 2013). Trait theory The trait theory is another important approach, which can enhance the efficiency of training and development provided to individuals working within the multinational companies of Malaysia. The trait theory is used to evaluate the behaviour of employees and their emotions and check, whether they are feeling interested in working for the company properly or not. The trait theory fosters the effectiveness of leadership across various groups of the organisation, focus on the behaviors of employees, and motivate them to perform to their potential (Long, Perumal and Ajagbe 2012). A Great Man theory TheGreat Man theoryis another appropriate theory, which shows the skills and abilities of leaders to act as a hero and influence others through their personal charisma, wisdom, intelligence. (Beh and Loo 2013). The great man theory of leadership has showed that leaders are born with necessary attributes, which have made them apart from others and these traits or behaviors are responsible for determining the authority and position of the organization too (Bello 2012). Summary of theories and models Theory and model Description Strengths Weaknesses Source Contingency The leaders apply their own style of leadership. Applying own leadership skills and expertise Lack of employees opinions (Bello 2012) Trait Fosters leadership effectiveness across various groups. Giving a proper direction to employees. Few groups remain out of focus as leaders may not be able to give equal attention to every groups (Anitha 2014) Great man theory The great man theory of leadership has showed that leaders are born with necessary attributes and determine the authority and position of organization The leaders care for the employees and promote diversity. Leaders often become aggressive of bringing out the best from employees (Elnaga and Imran 2013) Empirical studies The sample size is 200 respondents and the variable, which has been used is abc. Based on the findings, it could be understood that workers link the training and development sessions provided to customers with the organizations production level and more commitment. The training and development is related to the earnings per share and return on investments done for the training provided to workers. Summary of variables Variables Source 1. Vision Vision is to enhance organisational productivity through enhancement of workers performances (Ford 2014) 2. Core competency Allocating resources properly and manage differentiating of products. (Lee, Lee and Kang 2012) 3. Strategic direction Leading the employees in right direction and making them skilful through training and development. (Kennett 2013) H1: Training and development has created a positive impact on the performances of workers. H2: Training and development encourages motivation of employees. H3: The training and development has influenced the behaviors of employees and made them work with dedication. Conceptual framework Research design and methodology Research philosophy There are three different types of philosophies including the positivism, interpretivism and realism (Manzoor 2012). The research is primary, and so there is involvement of both quantitative and qualitative data. Interpretivism does not consider the scientific approaches, and so the assumptions made are subjective, which was needed to be objective. The quantitative data has been gathered through questionnaires distributed to customers, and so positivism research philosophy is considered here as the most effective (Mohamed et al. 2013). Thus, here the positivism research philosophy is the most effective among the other philosophies of research. Research design and strategy The three different kinds of research designs such as the exploratory, explanatory and descriptive. The exploratory research design defines the initial research and presents it with the help of theoretical data. It is useful for making observations and understands more about the research topic, which can help in carrying out the research in future as well. The existing theories and concepts can be used as well for developing an initial framework to conduct the research in the future. The explanatory research design determines the cause and effect of research and generate ideas about how things are communicated and are linked with each other (Ramayah, Ahmad and Hong 2012). The descriptive research design, as the name suggests is useful for exploring the various concepts of the research along with its variables in details. Thus, it could be understood that the descriptive research design focused on the what' and how' rather than why' (Salleh and Omar 2013). The dependent variable here is the performances of employees, and it is dependent upon the training and development, which is the independent variable (Sethi 2012). Thus, descriptive research design has helped in creating a positive impact of the independent variable on dependent variables for improving the performances of employees and contribute to the organisational efficiency. Data collection method The collection of data includes both primary and secondary data. The primary data includes both qualitative and quantitative data. The quantitative data is gathered in the form of responses and feedbacks of customers, which have been derived from the distribution of survey questionnaires to them. On the other hand, the managers of few of the multinational companies have been allowed to take part in the interview where they were asked certain questions and the answers provided are considered as qualitative data (Singh and Mohanty 2012). The secondary data is collected by following the secondary sources like journals, articles, blogs, newspapers, magazines and the internet web sites. The focus groups consist of a group of individuals who provide their responses and feedbacks for conducting a market research regarding the topic of the impact of training and development of performances of employees (Anitha 2014). The members of the focus group are selected properly for gaining their appropriate and authoritative responses in an effective manner. To check whether the questionnaires are reliable enough or not, the Cronbachs Alpha measurement had been used for making it easy for the respondents to answer the questions and it had been recorded as 0.907 (Bashir and Long 2015). It is above the normal reliability coefficient, so few changes are needed to be made though. Target or total population The targeted population is the number of employees working within Malaysian multinational companies. 500 questionnaires had been provided to the employees of the organisation, though nearly 200 had been returned. 11 questionnaires came back without any thing filled in those and 189 were used properly (Beh and Loo 2013). This resulted in delivering a yield of 95 percent while the partially filled up questionnaires had been returned to them as well. Sample size and Sampling method The sample size has been chosen as 200 employees and 50 managers of the most established multinational companies in Malaysia. For quantitative data, the sampling method is chosen as probability sampling method whereas for gathering qualitative samples, the non-probability sampling technique is more effective. The non-probability sampling method consists of purposive, convenient, availability and quota sampling (Bello 2012). The convenient sampling method provides the managers with a suitable time when they can be present and take part in the interview session to answer several questions asked by the researcher. The random probability sampling method helps in choosing random samples and distributes survey questionnaires to them for collecting quantitative data (Cherian and Jacob 2013). Data instrument The questionnaires are used along with Liker scale, which provides a range from 1 to 5. Variable Sub-Variable SA A N D SD Source Training 1. Gain practical skills 2. Knowledge acquisition 3. Enhance strengths 4. Makes employees handle critical situations (Bello 2012) Development 1 Training sessions 2 Role playing 3 Growth 4 Organisational success (Manzoor 2012) Leadership 1 Influences employee behaviour 2 Strengthening organisational position 3 Increase in organisational production 4 Guiding employees in right direction (Sethi 2012) Employee performance 1 Reward management system 2 Good working conditions 3 Training and development 4 Good work culture (Ramayah, Ahmad and Hong 2012) Accessibility and ethical issues The accessibility issues include lack of availability of managers, employees at the same time, which may make the researcher visit several places, and that is quite time-consuming. The questionnaires must be provided to respondents with a consent letter, and those should be tangible rather than being virtual (Elnaga and Imran 2013). There could be ethical issues in case the respondents do not want to participate. A power failure or network disruption could lead to loss of data and information. The research was conducted for academic purposes and not for gaining any commercial benefits (Ford 2014). Data analysis plan The data analysis has been done with the help of SPSS tool which can represent the data in the form of graphs and tables for making the researcher understand easily about the responses of individuals regarding the impact of training and development on performances of employees. The various ways of analysing data are reliability test, normality test, descriptive analysis, regression analysis, correction analysis and validity test (Giuliani and Macchi 2013). Analysis Reasons Source Normality test To check whether the data set is properly structured or not and how random variables are distributed (Salleh and Omar 2013) Reliability test For checking the data and information gathered are valid or not. (Sethi 2012) Descriptive It is used to manage proper design and ensure strategic formulation if research. (Manzoor 2012) Correlation Manage learning for linear association between two variables. (Mohamed et al. 2013) Regression For ensuring development and testing of software and manage changes in configuration, patches, software developments, etc. (Ramayah, Ahmad and Hong 2012) Research limitations Time and cost are the major constraints of the research while the respondents may also not provide the answers without bias. There are language barriers too, which can create difficulties for individuals to understand the questionnaires and for that, they may even skip few questions. Though the research has been completed within the allocated time frame, still some additional time and money are needed for completing the research in a much more detailed manner in the future too (Gunnigle, Lavelle and Monaghan 2013).

Managing Change The Case of FastLink Logistics Company

Introduction Contextual Information Cut-throat competition, technological advances, geopolitical realignments and other related pressures are combining with concerns for security, shifting customer demands, expansion urges and organizational governance to generate momentous pressure for organizational change (Howard, 1994). Current literature as demonstrated by Kotter (2007) reveals that organizations need to continually change and reinvent their strategies, structures, processes and culture to remain relevant as well as maintain competitive advantage.Advertising We will write a custom essay sample on Managing Change: The Case of FastLink Logistics Company specifically for you for only $16.05 $11/page Learn More But as observed by McGahan (2004), the change process itself need to be planned beforehand and aligned to the business strategy and objectives if it is to achieve success. The capacity of an organization to plan and implement the change process is therefore fundamental for success. By presenting a case of the current challenges facing FastLink Logistics Company, this paper will focus on providing an outline through which the underlying challenges can be adequately addressed by initiating a change process. Headquartered in Boston, MA, FastLink Logistics has been in operation for the last 20 years, and has consistently maintained a leadership position in the industry judging from its financial returns and competitiveness. An interview with the company’s operations manager revealed that the company operates a fleet of 3000 trucks and 10 cargo airplanes for purposes of transporting goods to various destinations across the U.S. and internationally. From the beginning of the current financial year, however, the company’s management has been receiving sustained customer complaints regarding delayed deliveries of their orders, especially from truck drivers. Indeed, some of FastLink’s traditional customers have opted to look for other logistics companies who keep their word on deliveries, implying that profits for FastLink Logistics have been on a downward trend. The management, having studied all the facts, identified massive paperwork in cargo clearing departments and irresponsible behaviour on the part of truck drivers, who engage in personal business while performing official duties. Upon holding several consultative meetings, the management decided to undertake a change process that will automate the clearing departments and install remote sensors on their trucks to monitor their movements and timeliness. The intended change process, however, is likely to experience some challenges, especially from employees who may oppose the intended automation of duties for fear of being rendered redundant. Still, truck drivers may feel that the intended introduction of remote sensors on their trucks may impinge on their privacy, hence perceive the new system negatively. Overall, the change proces s may be resisted by employees since it requires dramatic shifts in business processes and employee roles (Suntano et al., 2008). The management, therefore, must come up with strategies that ensure employee participation, commitment and identification to the change process so as to achieve success. In line with the above, FastLink’s management decides to enrol the services of a consultant to prepare a project feasibility study that could be effectively used to manage the change process.Advertising Looking for essay on business economics?

Get your first paper with 15% OFF Learn More Project Feasibility Study for FastLink Logistics Company The Project Scope Greer Conradi (2009) observes that â€Å"†¦the feasibility study usually refers to an assessment of the product/project against technical, operational, financial and social/political criteria† (p. 357). Academics and practitioners are in agreement that recognizing the challenges facing an organization and justifying the need for change must form the initial step of a system change effort (Suntano et al., 2008). Section A of this report demonstrates that FastLink is currently being faced with challenges arising from slower business processes and inability of some employees, particularly truck drivers, to identify with the values of the company. These challenges have caused the company to lose its traditional customers to competitors due to late delivery of orders, implying that the company’s profitability and competitive advantage in the market have been negatively affected. This particular feasibility study, hereafter identified as PFS, will therefore aim to come up with ways to balance business processes and technology constraints facing the firm so as to select a cost-effective solution. More importantly, the PFS will also involve matching the new system to organizational objectives in terms of deliverables, ability to meet customersâ⠂¬â„¢ requirements, efficient utilization of resources, budgetary allocations and time-frames. The PFS will be presented in the form of a short report. The Current Analysis FastLink logistics has for a very long time employed a manual process in its operations across all the offices located in the U.S. and abroad. This implies that the work environment has been largely paper-based and personnel-intensive. It is also imperative to note that FastLink’s working environment has been largely distributed over expansive geographical areas due to the nature of the transportation business. The advantages derived from the above working methodology may in fact be minimal as opposed to the disadvantages. In terms of advantages of the ‘status-quo’, it is important to note that manual processes of doing business in a way motivates employees to offer more, not mentioning that they are beneficial in aligning members of staff to organizational objectives and strategies (McGahan, 2004). A paper-based working environment also implies that information can be retrieved from the cabinets anytime without undue regard to other externalities such as the availability of power to run the machines, computer viruses, and end-user capabilities. In terms of the disadvantages arising from the current business processes, it is evident that FastLink has been losing, productively, due to delay occasioned by the tedious paper-based working environment and centralized information architecture.Advertising We will write a custom essay sample on Managing Change: The Case of FastLink Logistics Company specifically for you for only $16.05 $11/page Learn More Preliminary observations reveals that the distributed information architecture coupled with lax rules are to blame for the truck drivers’ unbecoming behaviour by virtue of the fact that critical information aimed at necessitating effective order deliveries to customers is either delayed due to the manual operational processes, or the information does not get to the intended recipients at all due to lax operational rules. Another problematic area for the company is the fact that it has to employ a large number of employees to do the paperwork needed to necessitate order deliveries, implying that the company’s wage bill may exceed profitable limits. These disadvantages, according to preliminary observations, are to blame for the company’s continued dip in profitability and competitive advantage within the logistics industry. According to Davies (1994), these challenges are functional in nature owing to the fact that they hinder effective work-flow processes for the company, thus they demand functional solutions. Benefits Pitfalls of the Proposed System The next stage of designing a project feasibility study, according to Greer Conradi (2009), is to develop specific objectives and limits of the proposed system. Here, it is proposed that the company redesig n and automate its database management system for the obvious advantages of faster and better customer service as well as ensuring the distributed use and processing of order information. Automated work systems, according to Howard (1994), not only simplify and streamline work processes, but they also enhance efficiency by curtailing excessive use of an organization’s scarce resources. The proposed remote sensors to be installed on trucks will go a long way to ensure that truck drivers follow their routes in the process of delivering orders to customers, and the orders are delivered on a timely basis. However, financial resources must be channelled to purchase the needed automation hardware and software as well as the remote sensors. The decisions to automate the offices and install remote sensors on trucks will most probably be met with resistance from members of staff who may fear loosing their jobs or who may argue that their privacy is being impinged on. Here, Suntano et al (2008) advises that the company should take an all-inclusive approach to enable employees participate in the change process; hence offer their views, fears and expectations as concerns the intended change. In addition, the management should exercise an open-door policy, whereby employees should be encouraged to raise any underlying issues and seek clarifications to better understand the proposed change.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More According to Davies (1994), involving employees and effectively answering their concerns in any change process is advantageous since it minimizes resistance during the implementation process, not mentioning that it facilitates employees to identify more with the change process once it is operationalized. Alternatives Companies in the 21st century are increasingly faced with the dilemma of whether to automate their operations or to continue with paper-based working environment (Alkuwaiti, 2010). In the present case, one of the viable alternatives would be to recruit more human resources to clear the backlog, hence necessitate timely delivery of orders to customers. Another alternative would be to enlist the services of security firms to escort trucks so that drivers do not engage in personal business during official working hours. The company may also consider investing in telecommunications to facilitate a more distributed information infrastructure. Assessment The assessment of any viable change process or alternatives must be evaluated against a backdrop of risk management controls, ability to meet fundamental objectives of the project’s attention, program needs and costs, intensity of effort, time-scale, security features, and flexibility for future modification and expansion, among others (Kotter, 2007; Bryce, 2011). It is indeed true that the proposed automated process may in the short-term be costly for the company in terms of purchasing the needed hardware and software as well as training staff members to operate the automated systems. In the long-term, however, the company will largely benefit from enhanced customer satisfaction, improved sales and reduced overhead costs. The alternative of employing more members of staff to clear the backlog may not be tenable in these circumstances, especially when the company is working on new modalities that will enable it to return to profitability and maintain competitive advantage. The time-scale needed f or implementing automated systems and installing the remote sensors may indeed be minimal when it is compared to the time-scale and resources needed to advertise for positions, recruit, orient and train new members of staff. According to Howard (1994), companies must always be on the lookout for proposals that enhance value creation as well as offer viable solutions to the problems that triggered the change process. In this perspective, the proposed system change should be recommended over the other stated alternatives. Automation of business process and introduction of remote sensors for trucks seem the only way to go for FastLink Logistics Company if it has to overcome its present challenges. Lastly, it is indeed true that automated systems can be expanded or modified to meet future needs and expectations (Suntano et al., 2008). The same cannot be said of other alternatives such as utilizing security firms to make the company drivers toe the line. List of References Alkuwaiti, A. J. (2010).

Linear Solution Essays

Linear Solution Essays Linear Solution Essay Linear Solution Essay CHAPTER 8 Linear Programming Applications Teaching Suggestions Teaching Suggestion 8. 1: Importance of Formulating Large LP Problems. Since computers are used to solve virtually all business LP problems, the most important thing a student can do is to get experience in formulating a wide variety of problems. This chapter provides such a variety. Teaching Suggestion 8. 2: Note on Production Scheduling Problems. The Greenberg Motor example in this chapter is largest large problem in terms of the number of constraints, so it provides a good practice environment. An interesting feature to point out is that LP constraints are capable of tying one production period to the next. Teaching Suggestion 8. 3: Labor Planning Problem- Hong Kong Bank of Commerce. This example is a good practice tool and lead-in for the Chase Manhattan Bank case at the end of the chapter. Without this example, the case would probably overpower most students. Teaching Suggestion 8. 4: Ingredient Blending Applications. Three points can be made about the two blending examples in this chapter. First, both the diet and fuel blending problems presented here are tiny compared to huge real-world blending problems. But they do provide some sense of the issues to be faced. Second, diet problems that are missing the constraints that force variety into the diet can be terribly embarrassing. It has been said that a hospital in New Orleans ended up with an LP solution to feed each patient only castor oil for dinner because analysts neglected to add constraints forcing a well-rounded diet. Alternative Examples Alternative Example 8. 1:  Ã‚  Natural Furniture Company manufactures three outdoor products, chairs, benches, and tables. Each product must pass through the following departments before it is shipped: sawing, sanding, assembly, and painting. The time requirements (in hours) are summarized in the tables below. The production time available in each department each week and the minimum weekly production requirement to fulfill contracts are as follows: | | |Minimum | | |Capacity | |Production | |Department |(In Hours) |Product |Level | |Sawing |450 |Chairs |100 | |Sanding |400 |Benches |50 | |Assembly |625 |Tables |50 | |Painting |550 | | | |Hours Required |Unit | |Product |Sawing |Sanding |Assembly |Painting |Profit | |Chairs |1. 5 |1. 0 |2. 0 |1. 5 |$15 | |Benches |1. 5 |1. 5 |2. 0 |2. 0 |$10 | |Tables |2. 0 |2. 0 |2. 5 |2. 0 |$20 | The production manager has the responsibility of specifying production levels for each product for the coming week.

The products require the labor and materials per batch that are shown in the table. Each batch of Grade A phosphate yields 800kg of phosphate; each batch of Grade B phosphate yields 700kg of phosphate; and each batch of Grade C phosphate yields 800 kg. |Grade |Grade |Grade |Available | | |A |B |C |Resources | |Labor hours |4 |4 |5 |80 hr | |Raw material #1 |200 |300 |300 |6,000 kg | |Raw material #2 |600 |400 |500 |5,000 kg | Formulate as an LP problem to maximize profit.

The eight variables correspond to the eight materials available (three alloys, two irons, three carbides) that can be selected for the blend. Six of the constraints deal with maximum and minimum quality limits, one deals with the 2,000 pound total weight restriction, and four deal with the weight availability limits for alloy 2 (300 lb), carbide 1 (50 lb), carbide 2 (200 lb), and carbide 3 (100 lb).

If constraints 5 and 11 are relaxed (or removed), one solution is X2 = 83. lb (alloy 2), X6 = 50 lb (carbide 1), X7 = 83. 6 lb (carbide 2), and X8 = 100 lb (carbide 3). Cost = $34. 91.

This problem, suggested by Professor C. Vertullo, is an excellent exercise in report writing. Here is a chance for students to present management science results in a management format. Basically, the following issues need to be addressed in any report: (a)  Ã‚  As seen in Problem 8-18, there should be 61 medical and 29 surgical beds, yielding $9,551,659 per year. (b)  Ã‚  Referring to the QM for Windows printout, there are no empty beds because the slack for constrain 1 has a value of 0.. (c)  Ã‚  There are 876 (the slack for constraint 2) lab tests of unused capacity. (d)  Ã‚  The x-ray is used to its maximum (slack for constraint 3 is 0) and has a $65. 5 dual price.

Solution to Chase Manhattan Bank Case This very advanced and challenging scheduling problem can be solved most expeditiously using linear programming, preferably integer programming. Let F denote the number of full-time employees. Some number, F1, of them will work 1 hour of overtime between 5 p. m. and 6 p. m. each day and some number, F2, of the full-time employees will work overtime between 6 p. m. and 7 p. m. There will be seven sets of part-time employees; Pj will be the number of part-time employees who begin their workday at hour j, j = 1, 2, . . . , 7, with P1 being the number of workers beginning at 9 a. m. , P2 at 10 a. . , . . . , P7 at 3 p. m. Note that because part-time employees must work a minimum of 4 hours, none can start after 3 p. m. since the entire operation ends at 7 p. m. Similarly, some number of part-time employees, Qj, leave at the end of hour j, j = 4, 5, . . . , 9. The workforce requirements for the first two hours, 9 a. m. a nd 10 a. m. , are: F + P1( 14 F + P1 + P2 ( 25 At 11 a. m. half of the full-time employees go to lunch; the remaining half go at noon.

At the end of the fifth hour, those leaving must be drawn from the P1 – Q4 remaining plus the P2 that arrived at the start of the second hour: Q5 ( P1 + P2 – Q4 Similarly, for the remainder of the day, Q6( P1 + P2 + P3 – Q4 – Q5 Q7( P1 + P2 + P3 + P4 – Q4 – Q5 – Q6 Q8( P1 + P2 + P3 + P4 + P5 – Q4 – Q5 – Q6 – Q7 Q9( P1 + P2 + P3 + P4 + P5 + P6 – Q4 – Q5 – Q6 – Q7 – Q8 To ensure that all part-timers who began at 9 a. m. do not work more than 7 hours: Q4 + Q5 + Q6 + Q7 ( P1 Similarly, Q4 + Q5 + Q6+ Q7 + Q8 ( P1 + P2 Q4 + Q5 + Q+ Q7 + Q8 + Q9 ( P1 + P2 + P3 Finally, to ensure that all part-time employees leave at some time: P1 + P2 + P3 + P4 + P5 + P6 + P7 = Q4 + Q5 + Q6 + Q7 + Q8 + Q9 The resulting problem has 16 integer variables and 22 constraints. If integer programming software is not available, the linear programming problem can be solved and the solution rounded, making certain that none of the constraints have been violated. Note that the integer programming solution might also need to be adjusted- if F is an odd integer, 0. 5F will not be an integer and the requirement that â€Å"half† of the full-time employees go to lunch at 11 a. m. and the other half at noon will have to be altered by assigning the extra employee to the appropriate hour. 1. The least-cost solution requires 29 full-time employees, 9 of whom work two hours of overtime per day. In actuality, 18 of the full-time employees would work overtime on two different days and 9 would work overtime on one day. Fourteen of the full-time workers would take lunch at 11 a. m. and the other 15 would take it at noon. Eleven part-timers would begin at 11 a. m. , with 9 of them leaving at 3 p. m. and the other 2 at 4 p. m. Fifteen part-time employees would work from noon until 4 p. m. , and 5 would work from 2 p. m. until 6 p. m. The resulting cost of 232 hours of straight time, 18 hours of overtime, and 126 hours of part-time work is $3,476. 28 per day. This solution is not unique- other work assignments can be found that result in this same cost. 2. The same staffing would be used every day. In fact, one would expect different patterns to present themselves on different days; for example, Fridays are usually much busier bank days than the others. In addition, the person-hours required for each hour of the day are assumed to be deterministic. In a real situation, wide fluctuations will be experienced in a stochastic manner. The optimal solution results in a considerable amount of idle time, partly caused by the restriction that employees can start at the beginning of an hour and leave at the end. Eliminating this restriction might yield better results at the risk of increasing the problem size.

Pathways to entry into the practice of professional nursing is Essay

Pathways to entry into the practice of professional nursing is confusing - Essay Example I strongly believe that these numerous entry points are not confusing, but they offer a range of benefits to nursing candidates. When there are many entry points to the practice of professional nursing, candidates get a great exposure to several potential entry choices. The numerous entry points greatly assist students to choose the most appropriate one by giving specific focus to their long term career goals, opportunities for college entrance, and personal and work obligations. These options are also beneficial for candidates to choose the most affordable entry point and avoid excess financial burden. To illustrate, as Black (2013, p. 134) purports, typically the annual cost of diploma and associate degree programs is less than baccalaureate degree programs. Those candidates who choose to attend local schools and live at home may incur lesser costs than students attending schools at distance and living in hostels. Hence, they can thoughtfully identify the entry point that would best fit to their financial interests. Another potential benefit is that students can take the issues of accreditation and articula tion into account while considering entry choice. Similarly, the emerging entry points address various issues associated with traditional entry points, and therefore students can avoid unnecessary concerns associated with their entry into the nursing profession. To sum up, the numerous entry points do not cause any confusion to students who have a clear vision of their long term career goals and financial potentials. Maneval, R. E & Teeter, M. M. (2010).
