Middle School Speech Essay Example for Free

Middle School Speech Essay I have been at Englewood School for four years. I am pleased to say that during these years I have created new friends and lived many exciting experiences. As a new student in third grade, my classmates and teachers made me feel as if I was among my family. From class time discussions to Christmas plays, we have enjoyed every single day within this community. Days filled with joy, laughter, and even sometimes sorrows have been our foundation to move to our next step. Our teachers have completed their mission and successfully prepared us for middle school. Our future experiences will be influenced from the exciting and moving moments that we cherish from the elementary years. Although we cannot go back to relive the moments we have spent together, we will remember them forever. During the upcoming years we will encounter difficult tasks but those will only make us stronger. We have to look forward to this new beginning. We must work hard, enjoy and above all, we must always stand together and united as we are today. The change we will face is not an easy one. As every other class before us we have been the oldest and the roles models for the little ones. Now, we will enter a new stage in which we will be the youngest and the new kids on the block. As we live new experiences, we must be prepared to win or lose. As long as we make the best of it, we will not regret it when looked back. Today we close a chapter of our school life. Tomorrow we begin writing another. Let us make that writing on our new chapter an interesting one. Thank you for being part of this class and let’s enjoy our future together.

Social Media marketing is modern marketing communication tool that helps marketers to engage with customers, prospects and other stakeholders of the business online. These are relatively low-cost communication channels that help firms to personalize theirs brands among the target audience. Primarily social media marketing assists companies to spread their intended messages mainly with the use of words, videos and photos. Some of the widely used social media channels are Facebook, LinkedIn, Twitter, Google+, Pinterest and Myspace. One of the major objectives of social media marketing is to communicate product and service offerings to those who interested in and also to make them visible to new target markets. Importantly social media channels create brand personalities, strong presence and relationships within the selected audiences. Social media provides firms with the opportunity of creating repeat and loyal customer base. The flowing can be identified as some key differences between social and traditional media tactics. Building relationships through adverts It is evident that there’s less or no interaction with target audiences with the use of traditional media tactics. They will only help firms to present their product or service. Whereas with use of social media, companies will be able to truly interact with customers and will help to build sustainable relationships through active and real communication. Operates within the boundaries of internet Traditional media tactics go beyond internet to try to reach people in off-line. Even today there are significant amount of customers who are yet connect online due to a number of reasons. By concentrating only on social media tactics, a company would not be able to communicate ... ... as 1) to determine whether the campaign adds value to the brand 2) to determine any necessary changes to make to the campaign 3) to obtain customer feedback 4) follow up leads. The effectiveness of a social marketing program will mainly depend on the following factors, 1) Align with the set objectives of the campaign (Targeted and focused) 2) Effects on brand awareness and reach (Number of people follows on Twitter; number of Facebook likes, number of downloads etc.) 3) Lead generation (people who shown interest via Twitter, returning visitors etc.) 4) Sales/ conversion rate (online purchases, favorable comments, referrals, number of people registered) 5) Level of interaction/ dedication of the marketing team (regular updates, comments, tweets) 6) Value additions within the campaign (games, mobile apps) – encourage people to actively participate in the campaign.

Partnership Working Essay

Partnership work is essential when providing person centred support and it also the only way to address some of the govements most challenging long term social objectives. The national services frame work for older people 2001 (24-25) also outlines expectations around integrated working bet between health services and social care agencies working towards a single assessment process and joint commissioning. The health act reinforces the importance of joint working The white paper July 2012 also state about working together long term paths and goals for a single assessment proses all working together to ensure all needs are met and people are in control know where to go and how to access making it easier to get what you need and when preventing delays lack of support the wrong support etc. Change work in partnership and provide the services people need and want in a streamlined and readily accessible manner. When organisations work closely together it has a positive impact on peoples lives. When they develop shared protocols and co-ordinated interventions, people are able to access and use services more easily and effectively. It requires innovation and leadership and leads to reduced time, cost and duplication as well as simplified and accessible services, which improve wellbeing. Successful partnerships need will address the tensions between structures and cultures particularly in relation to national targets. They need to face the challenges associated with integrating services that are based on fundamentally different principles of governance and different types of central and local government accountability. The outcome is always to improve the quality of life and improved health and emotional wellbeing for all individuals using or needed services. At a time when the whole of the public sector must find significant savings, reports are saying: that integrated working across health and social care offers opportunities for efficiencies and improvements to services. Without it there is a risk of duplication and cost shunting where savings made by one organisation or sector create costs for others. And a lack of integrated working means that people are less likely  to receive the best care. Some of the Befits of good partnership working Being able to offer a whole informed service Being able to tap in to resource which other agency hold which leads to a better outcome for the service user Assistance and help from appropriate people single assessment approach†¦ helping the individual reduce the need to repeat their story to different professionals Clear roles and responsibilities Being able to put in place effective and safe practices around confidentiality and information sharing services user has a legal and moral right to know what information is being shared regarding them The sharing of knowledge and good work practices Services user and staff know when to access further support and how to gain that it in turn providing both with more confidence and better service provision and better outcomes for the services user Benefits for people Services designed to meet people’s needs Improved choice and control Independence and inclusion Targeted help Benefits for partnerships Sharing of knowledge and understanding Pools resources Reduced cost, time and duplication Strong local ownership Benefits for organisation Increased capacity to deliver community services Increased satisfaction with the service Improved performance assessment Improving information sharing between professionals. Improving the efficiency of the care system as a whole. Co-ordinating the provision of care. Improving the planning and commissioning of care so that health and social care services complement rather than disrupt each other. Some of the general Problems with partnership working Despite the introduction of government legislation and initiatives during this time to promote closer multi-agency partnership working there is still: A lack of information sharing across agencies and services Duplicated assessments to identify needs and subsequent provision Poorly co-ordinated integrated activities across agencies Too much ‘buck passing’ and referring on of clients between agencies A lack of continuity and inconsistent levels of service provision Unclear accountability. Despite longstanding support for joint working, it has been beset by problems across all client groups that have been found. Delayed discharges from hospital, mainly of older people. These involve cases when a patient cannot leave hospital because of the unavailability of health or social care services in the community or because of administrative issues within hospitals. NHS cuts to continuing healthcare. This has led to disputes between NHS and social care professionals and shunted costs on to councils, who often have to fund care packages for people no longer fully funded by the NHS. The break-up of community mental health teams. In some areas of England councils have withdrawn social care staff from mental health teams, run by mental health trusts, because of cost pressures or concerns over trusts’ approach to issues including adult safeguarding and the  personalisation of care. A lack of NHS engagement in child protection and a lack of co-ordination of health and social care services for children. Pooled budgets have not translated into improved outcomes. Formal partnership arrangements in some areas have been scrapped following disagreements between partners. More generally, barriers to good partnership working include: Health and social care agencies facing different government performance regimes. Health and social care agencies using different IT systems. Cuts in one budget creating demand pressures in the other. Health and social care staff being on different terms and conditions in integrated teams. Policy and legislation on joint working Some of the agency challenges Financial resources: conflicts within or between agencies, a general lack of funding, concerns about sustainability, staffing. Roles and responsibilities: understanding the roles of others, conflicts over areas of responsibility, the need to move beyond existing roles. Non-financial resources: Time, staff, Communication, Being able to talk to the right person at the right time, All parties getting the information, Build the communication link up, Getting the right people together. Professional and agency cultures: Polices and procedure, training, ways of working, finances knowledge Management: how the management work, how they train and inform the staff the working philosophy, support, structure Government plans and initiatives towards partnership working Under section 75 of the NHS Act 2006, NHS bodies and local authorities in England can pool budgets, join together their staff and management structures or delegate commissioning responsibilities to each other. The Local Government and Public Involvement in Health Act 2007 require primary care trusts and local authorities to produce joint strategic needs assessments of the health and well-being of  their populations. This should shape joint planning of services. The Health and Social Care Bill would establish health and well-being boards in every local authority area to co-ordinate the The 10-year plan for social services, published in 2011, also includes plans to drive integration, for instance by requiring councils and health boards to jointly commission and arrange enablement services, to support people to regain independence. Good practice in joint working The while paper No secrets Outcomes inspected by CQC†¦. etc. What is working in partnership and why is it important Partnerships are about a way of working together rather than about a way of meeting together they involve the dissolution of organisational service and sometimes geographical boundaries and are about overcoming the constraints that these can place around effective outcomes and behaviour Partnership is therefore about focusing on objectives and outcomes that require considerable mutual understanding and trust in order to achieve them, including an awareness of the way in which they can contribute to the objectives of each organisation Crucially, this is likely to mean that the activities of individual members and member organisations will be carried out in a way that contributes wider benefits and longer term gains than if they were carried out in isolation. Partnership working is perhaps best seen as a spectrum, ranging from informal networking forums, consulting and sharing an information and intelligence, through to formal strategic alliances where partners come together to achieve common goals by changing the way that they work. It is critical for partnerships to understand where they lie on this spectrum as it will shape the way the partners work together, the commitment required and the achievements expected. There can often be confusions among partners about the nature of the partnership and this can seriously undermine progress. Partnerships should focus on doing those things that only they can do by working together – and that no-one  else can do better or more efficiently on their own. They should ensure that all the required members are round the table and that they are represented at the right level, and that they have ways of drawing on a much wider range of insights, experience, perspectives and expertise. Organisations should encourage and support partnership working across all their staff. They should offer opportunities to develop partnership skills and they should recognise and reward effective partnership behaviour. Good training and information on partnership working to staff so they can ensure good partnership working that they have the knowledge to support the services users and their families to ensure on going best support and practises. The more partnership working we as an organisation can do the more effective safe and services user focused sevice we can deliver. Partnerships need to maintain a strong connection to clients in terms of: Being able to draw on the service user experience of support and the extent to which this helps them make progress in their lives Creating ways of involving service user in the design of services Capturing the difference that services user perceive in the accessibility, quality and coherence of services.

How to Start Green Fire With a Drop of Water

You dont need a match to start a fire. In this project, start a fire by adding a drop of water to a dry chemical mixture. The best part? The flames will be green! Fire Safety You should be able to tell from the premise that this  is an adult-only project, best performed by someone with prior pyrotechnic project experience. Follow the instructions carefully to minimize the risk of a fire. Youre using water to start a combustion reaction, so keep your materials away from moisture, soft drinks, perspiration, etc. Got it? Green Materials Instant cold pack (3 grams ammonium nitrate)7 grams zinc filings or powder1/2 gram table salt (sodium chloride)Mortar and pestle If you dont have a cold pack, you can use pure ammonium nitrate, which is available online. You can buy zinc filings or powder online or you can sand a galvanized piece of metal from a hardware store to get the element. If you have to file or sand the zinc, its a good idea to wear a mask, such as the kind used for home repair,  so you dont inhale zinc particles. Procedure for Starting the Green Flames Open the cold pack. Remove and discard the bag of water. Open the bag of ammonium nitrate. Measure out 3 grams of the granules and put them in the mortar.Add 1/2 gram of sodium chloride (salt).Use the pestle to grind together the salt and ammonium nitrate to form a powder.Carefully grind the 7 grams of zinc powder into this mixture. Water can ignite the mixture at this point, so dont spill your drink or drip sweat into the powder. Its a good idea to wear disposable plastic gloves, because you dont want the final mixture reacting with water on your hands.Transfer the mixture to a metal or otherwise fire-proof container. Take it outdoors to start the reaction. Use a pipette or other long-handled dispensing device to add a few drops of water. The reaction can be spectacular, so move back immediately. Another reaction you can do using these materials is to mix ammonium nitrate with zinc and initiate combustion by adding a few drops of hydrochloric (muriatic) acid.

Harry Potter - The Next Chapter - 1202 Words

Harry looked at me. He looked a little shocked, scared, and sad. Understandably. He had just read a letter from his dead mother. Our dead mother. How odd. I didn’t know how I would tell my living parents†¦ The Grangers. I eventually decided that they didn’t need to know. Whether they know they adopted me or they were obliviated and think I am their daughter, no harm would come to them by my not telling them about this. Harry handed my letter to Ron, who read it as well. â€Å"Blimey! So you two, you’re brother and sister? That’s bloody mad!† he exclaimed in his cute, crude, blunt way. â€Å"So, you get why you can’t tell anyone, right? Not even your family?† I asked Ron. â€Å"’Course, Mione, but you won’t even tell the Grangers?† â€Å"Why†¦show more content†¦Ã¢â‚¬Å"I think we should,† I say resolutely. Harry and Ron looked at each other. â€Å"Same here,† said Ron. Harry motioned to Ginny and Luna. â€Å"Hey guys, we have something to show†¦er†¦tell you†¦ just not here. Later. How about the astronomy tower at 9 o’clock? If you see Neville, tell him to come too, cool?† Harry said. Luna, Ron, his sister, and I showed signs of affirmation and Luna and Ginny scattered, probably to their common rooms to get their coats for the match. A few hours later, I was sitting in the Quidditch stands with Ginny, Lavender, and Parvati. Ron was actually playing quite well and had stopped several attempts on the rings. Harry was flying around very high, looking for the snitch and vaguely watching the proceedings with the Quaffle meters below. Every time Ronald made a save, Lavender, sitting to my right screeched in some unearthly pitch and blubbered over how wonderful he was. I wanted to vomit. And no, I wasn’t jealous. He didn’t like her, so there was nothing to be jealous of. Gryffindor and Slytherin were tied at 60-60. Harry seemed to finally see the snitch, and Draco, watching Harry, flew off after him. The two boys went into a steep dive and were moving so fast I felt queasy. Oh, Harry! Be careful!! I could hardly watch. Quidditch scared me. Watching my best friends flying at extremely high speeds, with heavy Bludgers flying around trying to knock them off their thin, little brooms to the hard ground, so far below.Show MoreRelatedHarry Potter : The Book Is Better1304 Words   |  6 PagesIn recent years, two books have come about to be immensely popular on the market.

Tidal energy Free Essays

1. Introduction Tidal energy is one of the renewable energies that have a promising hereafter as energy beginnings for the whole universe in general and for some states in peculiar. The purpose of this study is to discourse the current position of tidal energy in footings of engineering, runing rule, environmental effects and its hereafter development. We will write a custom essay sample on Tidal energy or any similar topic only for you Order Now The specific aims are:  · To sketch the current potency of tidal energy throughout the universe  · To discourse the engineerings up to day of the month  · To place the pros and cons of the current engineerings  · To indicate out the environmental impacts of tidal energy and if any accomplishments so far to relieve this consequence  · To discourse the possible hereafter developments 2. Background The Earth and the Moon continuously produce centrifugal forces on one another. This gravitative consequence creates a bump in the oceans confronting to the side of the Moon. A 2nd bump is produced by the centrifugal force due to the rotary motion of the Earth on the opposite side of it. Those two sides of the Earth are the two countries where high tides are produced. The usage of tidal energy has been started since 12th century for grain milling intents in England and France though it has been barely used due to decelerate gait of engineering developments and other inexpensive energy beginning rivals such as fossil fuels. There were no much researches and developments on the engineering and it did n’t acquire adequate attending till recent old ages. But those tidal Millss are the base for the development of modern tidal energy engineerings. 3. Tidal energy Status 3.1. World Tidal Energy Potential The universe ‘s 70 % of its surface covered by H2O has an ability of bring forthing 50000MW tidal current energy yearly ( Atlantis Resource Corporation, 2009 ) . Most of the countries sited in 3.1 are those countries with high potency of tidal energy resources available. But tidal energy is available all over the Earth though the sum of energy to be harnessed is smaller compared to the given 1s. 3.2. Current Tidal Energy Technologies Tidal energy is the energy exploited from the possible and kinetic flow of the tides. There are two presently matured engineerings used to pull out this energy. The possible energy of the tides is exploited utilizing tidal bombardments and the kinetic energy is extracted by the tidal current turbine engineerings ( Fergal O Rourke, 2009 ) . 3.2.1. Tidal Barrages Tidal bombardments are dams constructed at the oral cavity of estuaries to keep up the coming H2O by shuting the piece gates in either side which builds up a possible energy that can be converted in to electricity by utilizing turbines. This has similar rule like the hydro electric power coevals. Advantages  · No demand of fuel  · No waste and nursery gas production  · There is no H2O and air pollution  · Reliable production of electricity  · Predictable and renewable Disadvantage  · Expensive for bombardment edifice  · There is deficit of tidal bombardment sites Policy shapers and companies are loath to pass clip and money in research and development for a wider execution of tidal bombardment engineerings because of their high civil substructure costs and environmental issues. Alternatively, they are concentrating on new engineerings such as tidal current turbines which can minimise the cost of dam buildings due to their simpleness in working rule and suitableness to deploy in different countries of oceans. 3.2.2. Tidal current turbines Tidal current turbines utilises the kinetic energy of H2O currents to revolve the turbines for electricity coevals. The working rule is the same as the windmills that use the air currents to revolve the air current turbines. The transition of kinetic energy in to utile energy is carried out by two widely used turbine systems viz. horizontal and perpendicular axis turbines. Those are the chief competent right now and they are largely under active research stage with a batch of presentations and trials around the universe ( M.J. Khan, G. Bhuyan, M.T. Iqbal, J.E. Quaicoe, 2009 ) . The blades of Horizontal axis tidal turbines rotate about a horizontal axis which is parallel to the flow of H2O as shown in fig 3.3 below. Those constellations and type of blades are non the lone 1s developed so far. Those are merely samples to demo physically how the horizontal axis tidal turbines look like. The blades of Vertical axis tidal turbines rotate about a perpendicular axis which is perpendicular to the way of the flow of H2O as shown in fig 3.4. There are different blade constellations and types under this class though they are non given in this paper. Tidal current turbines have same advantage as the tidal barrages do but relieve the major disadvantages because of their inexpensive building costs and can be deployed in wider countries of the universe. Those are the grounds tidal current turbines are going more attractive and favorable over tidal bombardments and batch of researches and developments are focussed towards those engineerings. 3.3.
