After universe assigned an elderly gentleman by the name of Ken, it quickly became evident the reasoning behind his care. Ken was suffering the early stages of dementia often forgetting name calling and having short-term memory loss. According to the Alzheimers Association in Queensland, early stages of dementia involves the destruction of brain cells in isolated areas often with first signs universe short-term memory loss. He was also suffering severe arthritis of the left knee that seemed to be afflicting each of his elbows as well. Arthritis is a term loosely use to inflammatory, metabolic, or degenerative diseases involving one or more of the joints (Colliers Encyclopedia). It is a preval ent, crippling disease affecting tens of millions worldwide (www.arthritis.org/). The final health concern detect was Kens social unacceptance. Often reluctant to join in with conversations and games, Ken seemed very isolated and lonely, probably further reinforcing the signs of dementia setting in. decision maker SUMMARYOn completion of the weekly visits and looking back on the time spent with the residents, ... ... the facility encouraging a more sociable and homy setting.

There were 17 bands of Shuswaps that controlled the vast country ofBritish Columbia for 10,000 years and compulsory 56,000 square miles oftraditional land.

Basics of Ghost Stories :: Ghost Story Stories Ghosts Essays
Basics of ghost StoriesINTRODUCTIONThe ghost story writer has to attract the indorsers care straightaway. The way story begins is master(prenominal) and often links with the restof the narrative. The opening of a short story must try to engage the lector quickly. I think all ghost stories should always deliver a lot ofsuspense in it, to create anticipation and excitement. Some symbolic disapprove/place for example a knife, a key must play a major part in thenarrative. The story should also have a lot of detail to get thefeeling as if the reader is there to create different types ofatmospheres, such as horror, terror, and excitement. They should alsohave a mysterious end, to do work the reader go away thinking about it.Most people are interested in ghost stories because of the thrill andhorror that is in it. Ghost storys challenges us to see how much ofthe paranormal we can take onboard and because it is a story they canalways back away from it if it gets too unnerving.I have re ad Wish Master, in which a demon awakes from an ancient potthat is destroyed in a robbery in a museum. then the demon goes aroundasking people for their wishes and he always does something oppositeto fulfil the wish.Ghost stories always seem to be set in lone(prenominal) or isolated places. Thelanguage writers use to describe settings in ghost stories are usuallyquite unpredictable because there is a lot of descriptive use ofimagery to paint a specific kind of picture for the reader. Ghoststories gained prominence in the Victorian period and a lot of stainlessstories were written during this period. They were written toentertain and feed the imagination of the populace who were intriguedby stories of the supernatural.Atmosphere is mood the writer is trying to create in a story. It isimportant because it builds a good impression on the reader. It iscreated through the use of language tools such as similes, metaphorsand onomatopoeia. The atmosphere of the story is developed right f romthe beginning. It largely depends on the writers purpose/intentions.So you do expect different kind of atmosphere to be created in both ofthese stories because in the The Signalman Charles Dickens is tryingto scare the reader and in The Deadfall Ted Hughes is trying to geta message across. Atmosphere is important in building tension in thestory, which I believe is vital for a ghost story.In The Signalman by Charles Dickens the narrator meets a lonelysignalman. At first he seems to be scared of him.

They are go awaying not only to give up their life for their country, but also to lead likeminded men and women who are willing to do the same. They have to confine split second decisions that test who they are and will vastly impact the lives of those under their command. This is the type of person I want to be I want to be a Naval Officer.I realize that becoming a Naval Officer isnt going to be easy, that officers have to go through rigorous amiable and physical training before they can receive their commissions.

There be many approaches to learning in the zone of proximal development such as scaffolding, reciprocal teaching, cognitive apprenticeships and communities of learning, each with their own unique way of transporting the learner into an easier to a greater extent motivated state of learning.Comp bed to Pia draw offs theory of cognitive development where the child is seen to go through four stag es of development sensorimotor, preoperational, concrete operations, and formal operations, Vygotsky believed that the cognitive developmental process should be analysed through social contexts. He believed that this was a lifelong process that was influenced by social interaction with family, instructors, and friends in the cultural residential area surrounding the pupil. He emphasised the instruments that specific cultures provide to maintain thinking, and the idea that children use the instruments theyre given to build their own comprehension of the physical and inbred world. He named this the Zone of Proximal Development. Vygotsky defines this as the distance in the midst of the actual development level as determined by nonsymbiotic problem work and the level of potential development as determined through problem solving under adult pleader or in collaboration with more competent peers (Vygotsky, 1978, cited from McInerney and McInerney, 2006,part 1,ch 2,p58).During thi s m cognitive development takes place. Throughout this development the child is said to go through four stages of growth (Gallimore and Tharp, 1990) 1. Assistance in their bend from other more cap commensurate peers, parents, and teachers. 2. Growing independence from their more capable peers as they begin to build their own ideas by using self enjoin speech and assume responsibility for their learning. 3. Automation of response they develop, make the movement of idea automatic and internalise their thinking.Assistance from others is not needed. 4. De-automatisation and recursion constant practice of second is necessary so as not to lose the make outledge and re-enter the zone of proximal development. Sometimes there is always a movement between in and out of the zone of proximal development. Vygotskian principles are evident in e rattlingday teaching practices and are maintained by parents, peers and teachers who believe that using a social constructivist perspective for educa tion will give their child or pupils the opportunity to grow within themselves through the sustain of others from different levels of knowledge.Vygotsky believed that the role of the teacher using the zone of proximal development for learning is to find an appropriate stage of complexity for the learner to handle. This is called assisted learning. Teachers provide strategic support in the initial stages of learning, gradually diminishing as students gain independence (Woolfolk, 2001, p49). The teacher must simplify tasks so that they are manageable for the student to deal with. This guidance or help is called scaffolding. It is the support for learning and problem solving. The support could be clues, reminders, encouragement, breaking down the problem into steps, providing and lawsuit, or anything else that allows the student to grow as an independent learner. They provide students with the opportunities to further extend their current skills and knowledge.For example, think abo ut a mathematics problem. Assume that the learner has made good progress and the time has tot up to learn how to do a Pythagoras theorem question. We know that the leaner cannot complete the task independently but has enough knowledge to master the problem with the help from a mathematics teacher. The learner is in the zone of proximal development and will be able to benefit from the scaffolding, in the form of explaining, demonstrating and guiding by the teacher. enchantment doing this, teachers look for discrepancies between students effort and the solution they come up with.They are looking to fake the frustration and risk that the student encounters. also they model an idealised version of the act of learning so the learner can use it to help them solve their educational problems (Hausfather, 1996). The key to getting students to help themselves learn independently is not to make the students reinvent information or rediscover it themselves. The teacher must make the informa tion available for the learner to audition and work out their own ideas and solutions whilst allowing them to be open to advice from deal who are more informed on the subject. So although scaffolding is an extremely helpful lance for teachers to use in their teaching and their students learning, they must make sure that the child is educated in the right approach so as not to deter the child from making advances on their own educational capabilities.Cognitive apprenticeships have proved very useful over the centuries as an impelling form of education. The bond that is formed between master and apprentice is both personal and motivating. By working alongside more experienced people, young people are able to learn the tricks of the trade first hand. There is a creation of dialogue between student and teachers that goes beyond answering questions and engages in the cover more informally (Driscoll, 1994). Communication is important between master and apprentice and the teacher must learn to properly use proxemics, paralanguage, and kinesics right for the outcomes to be reached. The performances required of the learner are real and important and grow more complex as the learner becomes more competent (Collins, Brown, & Holum, 1991).Some academics believe that knowledge and skills learned in school have become separated from the everyday world. To compensate for this, many schools have adopted many of the features of apprenticeships. Apprenticeships in schools would focus on cognitive objectives such as reading, writing, problem solving and mathematical problems. There are six main features of cognitive apprenticeships 1. Students esteem an expert model the performance2. Students get external support through coaching or tutoring 3. Students receive conceptual scaffolding, which is then gradually faded as the student becomes more competent and salutary 4. Students continually articulate their knowledge putting into words their understanding of the processes and content being learned. 5. Students reflect on their progress, comparing their problem solving to an experts performance and to their own earlier performances 6. Students are required to explore new ways to apply what they are learning ways that they have not safe at the masters side. (Woolfolk, 2001)In the classroom there is normally one teacher to 30 or so students, so where is there time for cognitive apprenticeships? Often there are students on the class that are at a much higher level of capabilities than other less capable students. Teachers put these students into groups where they can learn at a comfortable rate whilst have been immersed in a master and apprentice style learning environment.An example of a cognitive apprenticeship is the notion of reciprocal teaching. This is a method based on modelling, to teach reading comprehension strategies. The goal of reciprocal teaching is to help students understand and think deeply about what they read (Palincsar, 1986). Pali ncsars explore has focused attention on strategies that improve reading comprehension. In Brown and Palincsars 1989 case study students and teachers took it in turns to lead small group discussions on an important issue. They were shown 4 reading strategies and the students began to teach themselves.This type of educational style showed profound gains over other instructional strategies as they did not allow students to gradually teach themselves. Research on reciprocal teaching has shown some remarkable results. just about research was carried out with students who were younger adolescents who can read fairly accurately so therefore the research doe not have results and data from students who are in a different age group and who are not very capable in reading comprehension skills. So the overall research is not very reliable, however of the students that was involved their reading abilities improved. Those who were in the lower bottom half of their class moved up to average or supra average level on tests of reading comprehension.Palincsar has recognized there are three guiding principles for effective reciprocal teaching (Palincsar & Brown, 1984). 1. The shift from teacher control to student responsibility must be gradual. 2. The difficulty of the task and the responsibility must match the abilities of each student and grow as these abilities develop. 3. Teachers should carefully observe the teaching of each student for clues about how the student is thinking and what kinds of instruction the student needs. By considering reciprocal teaching, instructional approaches are used to emphasise social interaction between students active constructions of meaning.In a community of learners, students and teachers together construct a culture that values the strengths of all participants and regard their interests, abilities, languages, and dialects. Students and teachers shift among the roles of expert, researcher, learner, and teacher, supporting themselves and each other. There are different ways to help create a community of learners. Collaboration is a technique that teachers and student can use to enrich their solutions to harder and complex problems. Students may work with small groups in the classroom, between small groups creating difference of opinions and with others on a larger scale. matchless of the advantages of having students work in groups solving problems is that they will be called on to explain their proposed solutions to one another (Woolfolk, 2001). Putting solutions into words usually improves problem solving. Collaboration provides divided up responsibility, enhanced communication, new questions, new answers, engaged learners and enthused teachers. Research suggests that computer technology is a cultural tool that mediates and internalises the students learning. Changing their learning contexts with different technology is a powerful learning activity (Crawford, 1996). With children learning more about computers at an earlier age they are able to interact with others that are not on the same level of ability as them, thus creating a technological community of learners.Teaching students in the modern era can guarantee a more exciting and unpredictable learning experience sort out by many in society. Vygotsky perspectives uphold many beliefs about how students learn. The zone of proximal development was and still is challenging modern thinking about effective teaching and learning in philosophical ways. By examining Vygotskys zone of proximal development teachers are able to recognise that students of similar ages will be experiencing similar concerns and interests but there will be differences for each individual. Each student is different. Different from adults, different from each other and as such teachers have to provide for these individual differences in each area of learning. The learning process is very active.Vygotsky emphasises the need for experience and social interaction and that t hey play a key role in development. The development of a student is an important factor in deciding on the subject matter to be taught, the resources and knowledge experiences to present, the teaching strategies to be used and the procedures for evaluating learning. In order to appreciate, transmit, correspond and cooperate with students, teachers and peers must know how they think feel and act at different ages. They must learn to use the zone of proximal development to help their students determine their own opinions and ideas on life itself in the classroom and in the home community. From assisted learning and the scaffolding style of teaching, to cognitive apprenticeships and a full community of learners, students are able to mature their knowledge levels through the zone of cognitive development so as to become a stronger and more inquisitive student during their educational years of schooling.

Leading Supply Chain Turn Around
Five eld ago, salespeople at Whirlpool state the companys tot twine stave were sales disablers Now, Whirlpool excels at limit the right product to the right institutionalize at the right time-while retentiveness in showory low. What made the difference? by Reuben C Slone a make out train Turnaround eading T hings would be very different today-for me, my colleagues, and my company if the votes of Whirlpools North the Statesn leadership team had swung in a different direction on May 3,2001.It was a move I hadnt expected Mike Todman, our executive vice president at the time, firm to go around the table and ask each member of his module for a thumbs-up or thumbs-down on the investment that Paul Dittmann and I had just offici bothy proposed. Did I look worried? I shadowert imagine I didnt, even though wed spent hours in individual meetings with each of them, postureting their ideas and buy-in. We thought we had everyones support. just now the facts remained Our proposal had a bigger price tag than any release kitchen stove investment in the companys history. We were asking for tens of millions during a period of general belt-tightening.Some of it was slated for recent hires, even as cutbacks were taking place elsewhere in the company. And Paul and I, the people doing the asking, were coming from the put up chain organization. Let me be clear The supply chain organization was the part of the business that Whirlpools salespeople were in the habit of calling the sales disablers in 2000. We were perpetually behind the octad testicle, tying up in bid manner much capital in finished goods inventory yet failing to provide the product availability our customers needed. Our availability hovered around 87%. Our colleagues grimly joked that in surveys on the de be intimatery performance f the four biggest appliance manufacturers in the U. S. , we came in fifth. 114 HARVARD BUSINESS REVIEW OCTOBER 200 U HBR The 2Xst-Century Supply Chain. spotlight An d here, with all the credibility that track record conferred on us, we were proposing an ambitious new suite of IT solutions intimately-nighthing, too, for which the company had little appetite. It had been just 20 months since Whirlpool North America had flipped the electric switch on a massive new ERP system, with less than desired effect. Normally, Whirlpool ships close to 70,000 appliances a day to North American customers.The day after we went live with SAP, we were able to ship about 2,000. A barrage of bad press followed. Even though the situation was soon righted (SAP remains a valued first mate), the consume of being treated as a sort of poster child for ERP folly had left scars. So imagine our relief when we perceive the first component part say yes. It was the executive who headed up sales to Sears. Paul and I looked anxiously to the next face, and the next.

Now that it was his turn to vote, he did it with a fiourishI am fully committed,he say,to moving our supply chain from a liability to a recognized competitive advantage.

Sales had risen to record takes in 2000 as our launch of well-nigh nnovative products coincided with an uptick in housing starts. With the stay put of the company chugging on all cylinders, there was only one thing holding us back our supply chain. Jeff called me into his office and gave me a two-word order heap it. If that constitutes a mandate, we had one. just it was up to us to figure out what fixing the sup ply chain would entail. At the legislate level, of course, its a fair formulation getting the right product to the right place at the right time all the time. That gets complicated very quickly, however, when you consider the scale of the challenge.Whirlpool makes a diverse pass of washers, dryers, refrigerators, dishwashers, and ovens, with manufacturing facilities in 13 countries. We sell those appliances in lOO countries, through retailers big and small and to the construction companies and developers that build new homes. In the United States alone, our logistics network consists of eight factory distri providedion centers, ten regional distribution centers, 60 local distribution centers, and nearly 20,000 retail and contract customers. M We needed to formulate a battle innovation that would include new information technology, processes, roles, and talents. however before we could begin to imagine those, we needed to define our st cropgy. Looking to the future, what would i t mean to be world-class in supply chain performance? The decision we made at this very early point in the process was, 1 think, a pivotal one.

Give a date, hit a date is what theyre asking for. This sounded familiar to me, coming from the automotive industry.In my previous position at General Motors, Id been involved in several studies that emphasized the psychology of delivery date commitments. Identifying Trade Partners Priorities. Moving upstream, we needed to understand the desires of our direct customers split. We conducted our own interviews to define requirements by segment. As well as looking at smaller retailers versus larger ones, we focused individually on Sears, Lowes, and Best Buy, our three biggest customers. And within the contract-builder market, we studied many subdivisions, from contract distributors and flatcar developers to ingle-family-home builders. We asked about their overall availability requirements, their preferences in communicating with us, and what they would like to see along the lines of e-business. We asked about inventory management and how they might want Whirlpool to answer in it. In all, we discovered 27 different proportions along which our performance was being judged, each varying in importance according to the customer. Benchmarking the Competition. Naturally, our customers expectations and perceptions were shaped in large part by what others in our industry were doing.So we benchmarked our competitors-primarily GE, which was our biggest rival. We ob tained cross-industry information and competitive intelligence from AMR, Gartner, and Forrester Research to make sure we had a broad and objective sagacity of supply chain capabilities. Then we mapped out what would be considered world-class (versus sufficient or transitional) performance for each of the 27 capabilities and how much it would cost us to delve that top level. It turned out that to prevail on every front would require a nitty-gritty investment of much than $85 million, which we knew wasnt feasible.It was time to get serious about priorities. Now that we had established the cost of world-beating performance, we asked ourselves For each capability, what improvement could we accomplish at a low investOCTOBER 2004 ment level, and at a medium level? We quickly staked out the areas where a relatively small investment would yield supremacy, usually due to an active strength. A few areas we simply decided to cede. Our plan was to meet or beat the competition in most areas , at minimum cost. Building for the Future. Strategy, of course, does not simply address the needs of the moment.It anticipates the challenges of the future. A final component of our supply chain strategy was identifying the probable range of future operating scenarios based on industry, economic, and technological trends. The point was to assure ourselves that our proposal was fat enough to withstand these various scenarios. To date, the planning has worked. Having set a course, weve been able to deal with situations we hadnt conceived of and to continue evolving in the alike(p) basic direction. Selling the Revolution I ts always a difficult decision-when to involve your internal customers in the planning of a major capital investment.Their time is scarce, and they typically 117 HBR T h e Spotlight Chain. dont want to be embroiled in the details of what you, after all, are getting paid to do. You must have your act together and have a solid plan to which they can respond. On the other hand, you cant be so far along in the process that youve become inflexible. You need to nurture a careful balance between seeking their guidance and selling your vision. Paul and 1 liked to think we had that mandate from Jeff Fettig to get the supply chain fixed. But it wasnt the frame of mandate that comes with a blank check.Like most well-managed companies, Whirlpool will not undertake a capital investment without a have business case. As a cost center in the company, we had to justify our project wholly on expense reductions and working capital improvements. Even if we viewd that better product availability would boost sales, we couldnt count those chickens in the business case. We spent an enormous amount of time talking with the brand general managers and others who would be needed. They said they had nothing more to add. But we persisted. I cogitate telling Paul, If they wont let us in the door, well go through the window.And if they lock the window, theres always the air vent. Along the way, wed been particularly concerned about cherry-picking. We knew that, in a company of smart businesspeople, the first reaction to a multimillion-dollar price tag would be, OK, what can I get for 80% of that score? And indeed, from a project management standpoint, we knew it was important to break out each component of the plan into a stand-alone initiative, reassert by its own business case. Yet we knew the whole thing came together as a sort of basket weave, with each part supporting and relying on multiple other parts.What helped here was our competitive analysis, in which we had plotted our capability levels against others. We charted our current position against our number one competitor on each dimension valued by customers, then extrapolated to show how, depending on the level We staked out the areas where a relatively small investment would yield supremacy, usually due to an existing strength. affected by the changes we were proposing. The Japan ese call this kind of consensus-building nemawashi (literally, it means root binding), and it is im thinkable to overstate its importance.Yet it is often neglected in the midst of a complex project. Note that, at the same time we needed to be meeting with key decision makers, we were also in the thick of the analysis and soma of the solution. In those early months, the project needed leadership in two directions the kind of work people typically refer to as needing a Mr. at bottom and Mr. Outside. I made sure we had sufficient consulting resources for the inside work while Paul and I devoted 50% of our time to the out-of-door work interfacing with the trade, outside experts, and internal stakeholders.In our initial meetings with these key people, wed essentially say, Heres what were doing. What do you think? Typically,the executive would half pay attention, half blow us off. But wed get some input. In a second meeting, wed show how our work had evolved to incorporate their ide as and others. Usually, wed see more engagement at this point. By the time we were asking for a three meeting, reactions were mixed. People were more or less on board, but some felt another meeting wasnt 118 of investment, we could overtake that company or allow the hoo-hah to widen.Sure enough, the competitive instincts of our colleagues kicked in. No one wanted to fall behind. Getting Focused O ne of the earliest successes in the retroversion of Whirlpools supply chain was the rollout of a new sales and operations planning (S&OP) process. Our previous planning environment had been inadequate. What passed for planning tools didnt go far beyond Excel spreadsheets. Now, we had the ability to pull together the long-term and short-term perspectives of marketing, sales, finance, and manufacturing and produce forecasts that all the participants could base their game plans on.We soon pushed our forecasting capability further by launching a CPFR pilot. The acronym stands for collaborati ve planning, forecasting, and replenishment, with the coaction happening across different companies within a supply chain. The idea is straightforward. Traditionally, we forecast how many appliances we will sell through a trade partner (Sears, for example) to a given HARVARD BUSINESS REVIEW Leading a Supply Chain TumarouiuL market And at the same time, that trade partner develops its own forecast.Each of us has some information that the other lacks. With CPFR, we use a Web-based tool to share our forecasts (without sharing the sensitive data behind them), and we collaborate on the exceptions. As simple as it sounds, it isnt easy to pull off. But we have, and its been a real home run. Within 30 days of launch, our forecast accuracy error was cut in half. Where we had close to 100% error (which isnt hard, given the small quantities involved in forecasting individual SKUs for specific warehouse locations), today were at about 44% or 45%.To put this in perspective, a one-point improve ment in forecast accuracy across the board reduces our total finished goods position by several million dollars. These were just two of many initiatives we launched in rapid succession after May 2001. A couple things were absolutely critical to keeping them all on track a highly disciplined project management office and stringent performance metrics. The key was to think big but focus relentlessly on near-term deadlines. We organized the change effort into 30-day chunks, with three new capabilities, or business releases, rolling out monthly-some on the supply side, some on the demand side.The job of the project management office was to ensure the completion of projects on time, on budget, and on benefit. Paul oversaw this for me. Also keeping us honest were new metrics and the man 1 brought in to enforce them. My colleague bottom Kerr, now general manager of quality for the North America division, was then in charge of Whirlpools Six Sigma program. Hes a real black belt when it co mes to performance management. It took some persuading, aimed at both John and the North American leadership team, before he was freed up and allowed to dedicate himself to the supply chain turnaround.But we absolutely needed his data-driven perspective. When one of my team would say, We need to take this action tofixthis issue, John would always counter with,Please show me the data that allowed you to draw that conclusion. Were these demands sometimes a source of irritation? Id be lying if 1 said they werent. But they forced all of us to rebuild the metric fact base and hone our problem-solving skills. By the third quarter of 2001, we had already done a lot to stabilize product availability and reduce overall supply chain costs.And, after a challenging fourth quarter, we took a huge step forward by implementing a suite of software products from i2, which specializes in supply chain integration tools. That was in January 2002. Six months later. Whirlpool had historic low inventorie s and a bear on high service level. Before the year was out, we were delivering very near our design of 93% availability across ail brands and products. (Momentum has since carried us OCTOBER 2004 well into the mid-nineties. ) We delivered slightly more than promised by reducing finished goods working capital by 10% and improving total cost productivity by 5. 1%.Our customers were voicing their approval. By May 2002, a blind Internet survey given to our trade partners showed us to be most improved,easiest to do business with, and most progressive. I remember that after these results came out, our VP of sales said, Youre good nowbut more important, youre consistently good. It was a turning point in the trades perception of Whirlpool. Engaging Talent I ve touched on the state-of-the-art technologies weve employed in our turnaround-the Web-based collaboration tools, the planning software, i2s rocket-science optimization-but let me correct any impression that this is a tory about te chnology. More than anything. Whirlpools supply chain turnaround is a talent renaissance. Its sometimes hard for us to remember how demoralized this 3,000-person organization had become. In 2000, many people in supply chain roles had been with the company for years and had watched in frustration as competitors outspent and outperformed us. Part of the problem was the massive effort required by the ERP implementation. As an early adopter of enterprise systems in our industry (SAP and other vendors got their start with process-manufacturing concerns like industrial chemicals).Whirlpool had bitten off a lot. With limited attention and resources to spare, it put other projects on hold. We took our eye off the ball in supply chain innovation and fell behind. As a newcomer, I tried to inject some fresh energy into the organization and give people a reason to be confident Paul Dittmann told me this project gave him a second race wind. Hes a brilliant guy, with a PhD in operations researc h and industrial engineering, and suddenly, he had the opportunity to innovate in ways he had only dreamed of in his first 20 years at the company.Other people benefited from changes to how we develop, assess, and reward talent. With help from Michigan State University and the American Production and Inventory Control Society (APICS), we developed a supply chain aptitude model. This is essentially an outline of the skills required in a top-tier organization, the roles in which they should reside, and how they need to be developed over time. And we created a new banding system, which expanded the allowance levels in the organization. Now people can be rewarded for increasing their expertise even if they are not being promoted into supervisory roles. 19 The 21st-century Supply Chain We also put a heavy emphasis on developing peoples project management skills. Here, we relied on a model developed by the intercommunicate Management Institute (PMI), a sort of standard for assessing a nd enhancing an organizations project management capabilities. I wanted as many supply chain professionals as possible to become PMI-certified, and not just because of the glut of projects we were facing at the moment. My view is that project managements disciplined planning and execution is just as vital to on-going operations management.After all, the only real difference between running an operation and running a project is the due date of the deliverable. Over time, my operating staff stopped dismissing project management as a lot of overhead from a former management consultant and car guy. Now theyre the ones insisting on things like project charters and weekly project reviews. Meanwhile, we hired at least(prenominal) 13 new people on the business side and at least as many more on the information systems side, and I made sure that every one of them was top-notch.To fill out our project management ranks, we recruited little people from companies with strong supply chains and from premier operations-oriented MBA programs like Michigan State and the University of Tennessee. Perhaps we were lucky that our talent drive coincided with a downturn in the consulting industry. On the other hand, it might have been the excitement of a turnaround situation that drew the best and brightest to Whirlpool. Finally, I wasnt so arrogant as to believe that my senior team and 1 didnt need development ourselves. We assembled a supply chain advisory board and chartered its members to keep challenging us.The group includes academics forefather Bowersox of Michigan State and Tom Mentzer of the University of Tennessee, and practitioners Ralph Drayer (the Procter & Gamble executive who pioneered Efficient Consumer Response) and Larry Sur (who mastered transportation and warehouse management in a long career at Schneider National and GENCO). Get a group like this together, and you can count on creative sparks flying. These experts keep us on our toes in a way no consulting firm could. Sustaining Momentum refrigerators, washing machines, and other products that appeal to a broad range of consumers.They are the equivalent of a supermarkets milk and nut running out of them has a disproportionately negative impact on customers perceptions. Were now formulating a supply chain strategy that allows us to identify these SKUs across all of our trade partners in all of our channels and to ensure that the replenishment system for our regional warehouses keeps them in stock. That constitutes the plan to sell part of the program. At the same time, for our smallest-volume SKUs, we are taking out all the inventory and operating on a pure pull basis, with a new, more flexible build-toorder process. The inventory avings on the small-volume SKUs helps offset the costs of stocking up on the highvolume SKUs. Were also working on the capability to set service levels by SKU. That is, instead of having one availability target for all our products, we are recognizing that some products are of greater strategic importance than others. Some of them, for instance, are more profitable. Some hold a unique place in our brand strategy. Again, its easy to grasp the value of being able to vary service levels accordingly. But in a sprawling business like ours, shipping thousands of different SKUs daily, its a very difficult thing to accomplish.We continue to develop new Web-based tools. Recently, weve been focused on system-to-system transactions, in which our system talks immediately to a customers system for purposes of transmitting orders, exchanging sales data, and even submitting and paying invoices. Weve rolled out this capability with a number of trade partners over the past i8 months. At the same time, we keep enhancing our Partner Store, which allows customers to check availability and place orders via the Internet. The site allows them to find near equivalents of models, for those times when a SKU is out of stock or retired. They can even find deals on o bsolete inventory.By the time this article appears in print, well also have implemented event-management technology, which will allow us to be more on top of the movement of goods through the supply chain. An event manager provides an alert whenever an action in the process has taken place-for example, when a washer is prankish into a container in Schomdorf, when that container full of washers is loaded onto a ship in Rotterdam, when the ship departs, when the ship arrives, when the container is drop off from the ship in Norfolk, when the container leaves the port via truck, and, finally, when the washer is unloaded at the Findlay, Ohio, warehouse.The result is that peoples attention is directed to what needs to be done. Well also be further along in our application of HARVARD BUSINESS REVIEW T 120 hree years into the project now, we continue to assign ourselves and deliver three new capabilities per month. This doesnt get simpler over time, either. As I write this, for example, w ere focused on something we call Plan to Sell/Build to Order. Here, the notion is that certain high-volume SKUs should never be out of stock. These are the heart-ofthe-line dishwashers. .lading a Supply Chain Turnaround ean techniques (usually associated with manufacturing operations) to our total supply chain. This involves using pull concepts and kanbanlike triggers to speed up processes, reduce inventory, and enhance customer service. On the Hoz4zon W hirlpool has much to show for its supply chain efforts. By the end of 2003, our product availability had reached over 93%, up from 88. 3% in 2001. (Today its more than 95%. ) That allowed us to attain an order fill rate for key trade partners of over 96%. The number of days worth of finished goods we were holding in inventory had dropped from 32. 8 to just 26.We drove freight and storage total cost productivity from 4% to 7. 2%. From 2002 to 2003, we lowered working capital by almost $100 million and supply chain costs by almost $ 20 million. Does all this add up to value in excess of the expense our leadership team approved? Absolutely. In fact, total payback on that original investment occurred within the first two years. Still, our work is far from finished. In October 2001, just months after we kicked off our turnaround, we were fortunate in that the new executive vice president brought in to run Whirlpools North America region had deep supply chain knowledge.Dave Swift, who came to us from Kodak, believes strongly in the strategic importance of the supply chain both for building brands and for creating sustainable competitive advantage. Immediately after joining us, he elevated our sales and operations planning process by personally chairing monthly executive S&OP meetings. These meetings have become the model for the company and the basis for much of our just-started global supply chain efforts. In the future, well face greater demands for end-toend accountability. Were already responsible for the resal e of any returns. Soon well be accountable for the disassembly of products in Europe.Its only a upshot of time before similar laws are enacted in the United States. And well be taking an even closer look at the design of the products themselves. If we can design a productOCTOBER 2004 make it in a smaller plant, make it with smaller parts, ship it in smaller pieces we can dramatically affect supply chain economics. Its great to improve forecasts, optimize transportation, and speed up our processes with existing SKUs. But what if we could push the end stages of production closer to the consumer and get higher leverage from those SKUs? Thats the kind of thing that can change the rules of the game.Its a wonderful thing about our business We have fierce competition all over the world, and on top of that we have very smart trade partners who deal with numerous other suppliers. We may be a white goods, big box supplier, but because our customers also buy electronics and apparel and so o n, were constantly being challenged by the benchmarks of other, more nimble industries. Technologies continue to evolve, channel power continues to shift, and the bar is constantly being raised. But Im confident that the talent in Whirlpools supply chain organization will be equal to it all. Reprint RO4IOG To order, see page 159. 121

Qualitative Analysis of Anions Essay
The objective of this experiment was to use qualitative analysis to determine the chemical substance characteristics of four known anions by systemic collateral testing. The chemical characteristics observed were to be used to identify an unknown model. Sulphuric acid was to be added to a carbonate ancestor and an effervescent reaction would confirm the forepart of carbonate anions. Another essay of carbonate firmness was to be reacted with hydrochloric acid and the gaseous harvest-feast was to be reacted with a suspend drop of barium carbonate. The front line of clouding in the droplet would also confirm the movement of carbonate anions. smooth nitrate was to be added to chloride upshot and the formation of a ashen flow, ash grey chloride, would confirm the charge of chloride anions. Ammonium hydroxide would be added to dissolve part of the precipitate.The resultant supernatant beginning was to be decanted and re-acidified with nitric acid to reform the precipitate a nd definitively confirm the presence of the chloride anion. Silver nitrate was to be added to iodide event and the formation of a yellow-bellied precipitate, silverish iodide, would confirm the presence of iodide anions. Another strain of iodide solution was to be reacted with drops of acetic acid until suitablely acidic. Potassium nitrate was to be added to the solution causing a colour flip-flop. Methylene chloride was to be added to this sample and shaken to confirm the presence of iodide anions by forming two separate and differently coloured levels. A barium chloride-calcium chloride garland was to be added to sulphate solution and heated to 90oC. The sample was to stand for a period of time to allow the formation of awhite precipitate, barium sulphate, sustain the presence of the sulphate anion. The extension of hydrochloric acid and subsequent passion were to devour no effect on the presence, further corroborate the presence of sulphate anions.MATERIALS AND METH ODSEQUIPMENTCHEMICALS turn out thermionic vacuum tubesCarbonate Solution,Test tube rackConcentrated Sulphuric acid, H2SO4Eye dropper6M Hydrochloric acid, HCLGraduated pipetteBarium hydroxide solution Ba(OH)2Pipette medulla oblongataChloride solution, Cl-Pasteur pipetteIodide solution, I-Beaker0.1M Silver nitrate, AgNO3ThermometerConcentrated Ammonium hydroxide, NH4OH6M Nitric acid, HNO36M Acetic acid.

The bottom layer was reddish-purple, and the top layer was an orange-brown 2 drops of acetic acid, HC2H3O2, were added to acidify sample Upon confirming the sample was indeed acidic, it reacted with the potassium nitrate to change to a mustard-orange colour. The addition of the methy lene chloride formed 2 distinctly coloured layers, thus confirming that the solution had iodide anions present. Table 8 Testing and confirming Unknown Sample for the presence of Sulphate SO42- anions0.5mL of BaCl2-CaCl2 mixture addedTest tube heated, stood for 10 minutes5 drops 6M HCl, test tube heatedUnknown Sample, 3mLno precipitate formedno noticeable precipitate formedno change to solutionIn each instance of heating, the test tube was placed in a stewing water bath at 90oC The final heating of the test tube was for approximately 5minutes at 90oC The lack of precipitate formation in the test indicated that the sample was absent of sulphate anions. This result was further confirmed by the subsequent addition of hydrochloric acid and reheating failing to produce a precipitate.DISCUSSIONA strengthened acid such as H2SO4, sulphuric acid, combined with carbonate produces an effervescent reaction due to the formation of carbon dioxide. The heat felt from the test tube was a result of the exothermic reaction that the carbonate solution underwent in the presence of a strong acid. Sulfuric acid is a strong acid, but only for the first H, so it dissociates into H+ ion and the bisulfate ion, HSO4-. HSO4- is a weak acid and does not dissociate to a great extent, but it also reacts with carbonate (Dartmouth College, 2003). The presence of sulphur may have accounted for the mildly unpleasant scent wafted during the experiment. As indicated by the results of Table 1b, the formation of CO2 acted as a positive index for the presence of CO32- in a solution, as expressed by 2H+(aq) + CO32-(aq) H2O(l) + CO2(g).The exposure of the produced gas, carbon dioxide, to barium hydroxide resulted in the a cloudy white precipitate due to the formation of barium carbonate as expressed by H2O (l) + CO2 (aq) + Ba2+(aq) BaCO2 (s) + 2 H+(aq). The addition of 01M AgNO3, silver nitrate, to the chloride solution resulted in the formation of a white precipitate due to the formation of silve r chloride as expressed by AgNO3 (aq) + Cl-(aq) AgCl(s) + NO3 (g). It is interesting to note that chlorides are generally soluble, with the exception of lead(II) and silver chloride. When concentrated NH4OH was added to the silver chloride precipitate dissolved due to the formation of an ammine complex, Ag(NH3)2+. Silver nitrate is generally acidified with dilute nitric acid to prevent the downfall of other non-halide silver salts (Brown, 2012).Nitric acid acidified the solution due to the addition of H+ ions to the solution, resulting in re-precipitation, thus definitively indicating the presence of chloride anions. This is expressed as AgCl(s) +2NH3(aq) Ag(NH3)2+(aq) + Cl-(aq) Ag(NH3)2+(aq) + Cl-(aq) + 2H+(aq) AgCl(s) + 2NH4+(aq) The addition of 0.1M AgNO3 to the iodide solution resulted in the formation of a cloudy yellow precipitate as expressed by AgNO3(aq) + I- AgI(s), which as a precipitate is indissoluble in concentrated ammonia. The addition of 6M acetic acid, HC2H3O2 , acidified the solution, as confirmed by the litmus test. The newly acidic solution reacted with potassium nitrite, KNO2, reducing the nitrite to nitrogen dioxide as expressed by I-(aq) + KNO2 KI(aq) + NO2(g). The liberation of iodine in the reaction resulted in a brownish change in colouration of the solution (SUNY Chemisty, 2005). The failure of the sample to turn a reddish-brown may have been a source of error due to a failure to sufficiently rinse the cleaned test tube with DI water.Methylene chloride, CH2Cl2, which is a non-polar organic compound was added to the solution reacted with the iodide in the solution to form a violet coloured layer of denser solution, which settled at the bottom of the test tube. An substitute means of testing for the presence of iodide anions would have been to use starch, which forma a characteristic blue-black complex. The addition of the barium chloride-calcium chloride mixture, BaCl2-CaCl2, to the sulfate solution resulted in the formation of an insoluble white sulphate, barium sulphate as expressed by Ba2+(aq) + SO42-(aq) BaSO4(s). Other insoluble barium salts contain anions of weak acids (CO32-, SO32-and PO43-). Precipitation of these anions is generally prevented by acidifying the solution (Yoder, 2014). The products of the reaction were made more prominent by the catalyzing the reaction with heat, resulting in a more noticeably fine white precipitate distributed throughout the solution.The addition of 6M HCl, hydrochloric acid, served to acidify the solution, further illustrating the insolubility of the barium sulfate precipitate, thereby confirming the presence of sulphate anions. The unknown sample was placed through all confirmatory tests. It failed to react with Sulphuric acid and hydrochloric acid to produce an effervescent reaction, indicating it was carbonate absent. Unknown Sample 7 did not react with the BaCl2-CaCl2 mixture to form a precipitate regardless of heat, indicating the absence of sulphate anions . Unknown Sample 7 formed a pale cloudy yellow precipitate upon the addition of silver nitrate, immediately indicating the presence of iodide anions, disqualifying the need to testfurther for chloride. The addition of acetic acid to Unknown Sample 7 provide a sufficient acidic environment for the potassium nitrate to release iodine, thus the solution appeared as a dark mustard orange. The methylene chloride confirmed the presence of iodide anion when a distinct reddish-purple layer settled at the bottom of another distinctly coloured layer of solution.CONCLUSIONBased on the results of the experiment, Unknown Sample 7 demonstrated the formation of a precipitate in the presence silver nitrate, a change in colouration when mixed with potassium nitrate, and the formation of 2 distinctly coloured layers when methylene chloride was added to the solution and shaken. In accordance with the chemical properties exhibited by the 4 known anions during the qualitative testing, it can be conclude d the Unknown Sample 4 clearly demonstrated the characteristic chemical responses of a solution with I- ions present.QUESTIONS1.
