Method and Reflection While researching about major depressive disorder, we tried to find valid articles that had a great explanation of the disorder. We were looking for deeper information as to why people have this disorder, how do they come about having this disorder and how/if people can overcome this common disorder. There was a great amount of resources through the internet with helpful information. The internet is a great resource because they even include several experiments to explain their research. Another method of research was looking through the library to find helpful books that are filled with information. To prevent any challenges as a group, we would get together and look over what we needed to accomplish. Then we would evenly divide the work load and send our information to each other when we were done. If we had any questions about the research or written aspect, we would reach out to each other via email and help each other. Discussion How is it that this disorder could have a negative impact on a personÃ¢â¬â¢s life? The negative impact on a personÃ¢â¬â¢s life with major depression disorder is endless. Unfortunately, there are no positive impacts that this disorder can offer in an individuals life. Relationships can quickly waver, work can slowly become a difficult task to complete properly, and self-esteem can be strongly effected in a negative way. All these things which harm an individual with this psychological disorder.

The trouble with television My viewpoints on the book written by Marie Winn Ã¢â¬Å"The Trouble with TelevisionÃ¢â¬ which talks about how television has a negative effects on children and family. IÃ¢â¬â¢ve read the book and I agreed with everything author Marie Winn wrote, so I have decided to argue for her on the major points of the book. My first argument for the book will be about the family, it talks about how Ã¢â¬Å"TV Keeps Families From Doing Other ThingsÃ¢â¬ , which it explains how a child that spends too much time watching TVs will miss out on a very important part of their learning development, because in the home its where much of the child learns an if the child is watching TV and not learning and bonding with their family, the television will turn off the process that transforms children into people. We will write a custom essay sample on Trouble with Television or any similar topic only for you Order Now My second argument will be about TVs is a hidden competitor for all other activities Ã this topic is about how TVs takes most of your time so you donÃ¢â¬â¢t have time to do anything else ,TVs is competing with every activities an TVs is the one of the reason why some activities people never get to do The book also says Ã¢â¬Å"That TVs takes the place of physical fitness and playÃ¢â¬ , I totally agree with that statement because too many kids are just watching TV, not doing any physical activities at all, studies are showing that people are watching more TVs an getting more obese due to a lack of physical activities, to me after finding that out too much TVs has such a negative effect on physical health, IÃ¢â¬â¢ve decide to cut down on the number of hours I spend watching TVs. TV has such a negative effect on school achievement ,that was one of the main points in The Trouble with Television book ,it explains how excessive TVs watching directly negatively affects the brain ,in other words Ã turns the brain into mush due to more watching TVs and less studying. In my opinion I agree with everything author Marie Winn wrote in The Trouble with Television book. I agree that too TVs is a big problem . I once use to watch TVs so much and never studied I was failing in school, and when I finally turned off the TVs and picked up a book, my grades an my life became so much better, when you turn off the TVs you come back to reality an so some world that wastes your time How to cite Trouble with Television, Essay examples

Pyramids Pyramids Imagine living in Ancient Egypt about 3,000 B.C. Imagine a society teeming with life and happiness. Imagine looking around and seeing beautiful buildings, fields of crops, and the great pyramids with their white limestone faade blazing in the sun of the midday. It would be quite the experience to have lived back then. The history of Egypt begins with the unification of Upper and Lower Egypt into one united kingdom. The first ruler under this new system was Menes. Thirty other dynasty's would follow. To further unify Upper and Lower Egypt Menes founded a capital city where the two met: at the apex of the Nile, where it fans out into the silt plain. This city was named "White walls" by the Egyptians but later called Memphis by the Greeks. It is here at Memphis that the great pyramids where built. The pyramids were built to house the dead pharaoh of that time. Death was seen by the Egyptians as just the beginning of a journey to the other world. In Egyptian society each individual believed that his eternal life was dependant on the continued existence of their king, a belief that made the building of the pyramid a concern of the entire kingdom. Many people would be called to duty to work on the pyramids and many would go at will. It was found that the Egyptian people actually liked working on the pyramids. Many youths would travel down the Nile to work on the pyramids so that they could see the great city of Memphis. Furniture and riches not to mention body parts of the dead king were buried with him in the pyramid, so that in the afterlife the king would be able to have all the comforts that he had in his life. Wives and people of high standing in the king's court were buried beside his tomb when they died. The queens pyramid was always much smaller than the kings. The other wives and attendants tombs were built beside the king's pyramid but were only small rectangular tombs or mastabas. In early tombs, the central area was the burial chamber. The other surrounding rooms contained the king's furniture, jewelry, and other things that were owned by the King. False doors of heavy stone represented passageways between these rooms and others. There were no real doors because it was believed that the king, in the afterlife, would be able to move about without the help of structural passageways. The first pyramid was the step pyramid of King Zozer built at Saquarra in 2750 B.C. The structure of the pyramid was that of six steps all of larger size if you were to decending from the top of the pyramid. I was 200 feet high and covered around 12,000 square meters. The pyramid was made mostly of limestone blocks and desert clay. Inside the pyramid Zozers burial chamber was quarried 25 meters below out of the rock beneath it. The tomb, like those that followed, was meant to be a replica of the royal palace. The pyramids built on the Giza plateau at Memphis are the largest of all of the pyramids. The largest is the Great Pyramid, or the pyramid of Khufu. It stands 450 feet high. The second largest is the pyramid of Khafre. It stands 448 feet high and still has some of the original limestone at the top. The third is the pyramid of Menakaure. The pyramids at Giza are primarily built of Granite and Limestone. The blocks of granite were quarried out of the plateau nearby and the limestone out of many different quarries as far away as fifty miles upriver. All the blocks were checked for dimensions with special rods made specifically for that purpose. Most of the blocks used for the main structure weighed about two and a half tons. In all, around 2,300,000 blocks of stone are used to build a pyramid, with a workforce of around 30,000 people. The burial chamber was built first and contained the largest and heaviest blocks, some weighing around 40-60 tons a piece. During the building of the burial chamber work was started on the procession ramp leading from the Nile river up to the pyramid. The ramp provided a way to get the king up into the pyramid after being embalmed and floated to the site. After the blocks were checked they would then be slid up slightly inclined ramps that were built on the side of the pyramid. As the pyramid grew, the ramps grew along with it curling up and around the pyramid on all four sides. The ramps were

Speech on Environmental Issues Today Essays Speech on Environmental Issues Today Essay Speech on Environmental Issues Today Essay Our Environment how can you and I help save it? Albert Einstein said Look deep into nature, and then you will understand everything better. Our planet is in trouble! Pretty much everywhere you look today you will hear or see something reminding you that our planetÃ¢â¬â¢s health is failing. If our planet where a person it would be about time to buy the burial plot and write out the last will and testament. Just a brief list of the things that is ailing her is pollution, acid rain, climate change, the destruction of rainforests and other wild habitats, the decline and extinction of thousands of species of animals and plants. nd so on. I think everyone in here can agree that all of these issues exist and that humans have caused them. Thankfully many of us are concerned about the future of our planet and unless we can find a way of solving the problems then the environment will suffer. I know this all sounds so depressing but we canÃ¢â¬â¢t get overwhelmed. Every one of us can do something to help slow down and reverse some of the damage. We cannot leave the problem-solving entirely to the experts we all have a responsibility to our environment.We must learn to live in way that will sustain our world like learn to use our natural resources which include air, freshwater, forests, wildlife, farmland and seas without damaging them. As populations expand and lifestyles change, we have to keep the world in a condition so that future generations will have the same natural resources that we have today. Here I am going to list just a few examples of the threats to our environment as well as some ideas to help you to do something about them. WasteWe humans create a lot of trash! Between 1992 and 2008 household waste increased by 16% and we now produce just under half a ton per person each year. Most of this trash is hauled away by the garbage man and buried in a huge landfill or it is burned. Both of these options are harmful in their own way. Is all our trash really trash? If you think about it, a lot of what we throw away could be used again. It makes sense to reuse and recycle our trash instead of just trying to solve the problem of where to put it!Much of our waste is made up of glass, metal, plastic and paper. Our natural resources such as trees, oil, coal and aluminum are used up in enormous amounts to make these products and the resources will one day be completely used up. So in order to cut down on the energy used lets reuse. What can you do? * Sort out your trash. Organic matter (e. g. potato peelings, left over food, tea leaves etc. ) can be put in to a compost heap in the garden and used as a good, natural fertilizer for the plants. Aluminum cans, glass bottles and newspapers are often collected from our doorsteps, but other items such as plastic bottles, juice cartons and cardboard may not be, in which case they can be taken to nearby recycling banks. You can find out where they are by just searching on line. * Use recycled paper to help save trees. Chlorine bleach is usually used to make newspapers and this pollutes rivers. Its better to use unbleached, recycled paper whenever you can. * Take your old clothes to charity shops.Some are sold, others are returned to textile mills for recycling. * Try to avoid buying plastic. Its hard to recycle. One way to cut down on plastic is to refuse to use plastic bags offered by supermarkets and use cloth re-useable shopping bags instead, or re-use plastic bags over and over again, until they wear out and then recycle them. Pollution The air, water and soil of habitats all over the world have been, and are being polluted in many different ways. This pollution affects the health of living things.Air is damaged by vehicle emissions, and power stations create acid rain which destroys entire forests and lakes. When fossil fuels like oil, gas and coal are burned to provide energy for lighting, cooking etc. they create polluting gases. Oils spills pollute sea water and kill marine life; chemical waste from factories and sewage, and artificial fertilizers from farmland, pollute river water, killing wildlife and spreading disease. What can be done? * DonÃ¢â¬â¢t litter. * Use less energy by switching off lights when rooms are not in use, not wasting hot water, not overheating rooms. Use a bicycle or walk instead of using a car when you can. Or rideshare, and use the HOV lane. * If you spot pollution, such as oil on the beach, report it. If you suspect a stream is polluted, report it to the local EPA office. . * Organic foods are produced without the use of artificial fertilizers and pesticides, preventing these pollutants from contaminating habitats and entering the food chain. So it may cost a little more but it is better for you and for the environment. The Greenhouse EffectCertain gases in the atmosphere, mainly carbon dioxide, methane, nitrous oxide and fluorocarbons, act like the glass in a greenhouse, allowing sunlight through to heat the Earths surface but trapping some of the heat as it radiates back into space. Without this the Earth would be frozen and lifeless. However, due to the Human Effect ,greenhouse gases are building up in the atmosphere, causing a greater amount of heat to be reflected back to Earth. This results in an increase in average world temperatures and is already causing more droughts, flooding and extreme weather conditions such as hurricanes which we have all seen on the news.Some ways to Help * Dont waste electricity or heat. Electricity and heating are produced by burning coal, oil and gas and this action gives off carbon dioxide. The more we use the more we pollute. * Car fumes produce carbon dioxide and nitrogen oxide so try to cut down on car trips if possible. Use a bike or walk its good exercise for you too! * Recycle as much of your waste as you can. Methane, the most effective greenhouse gas, is released into the air as the trash in landfill sites rots.Now I realize we canÃ¢â¬â¢t all live on a farm and grow our own food and all drive smart cars. We Texans normally canÃ¢â¬â¢t walk or take a bike places because everything is so far away. My dream job has always been one that I could ride a bike to, that sounds funny but every little bit helps. Some other things I did were to change out all of my light bulbs with energy efficient ones, and reinsulated my house. This and other things save me money but they also save the environment. Let me leave you with one last thing: Reduce, Reuse, Recycle!

Creating Delphi Components Dynamically (at run-time) Most often when programming in Delphi you dont need to dynamically create a component. If you drop a component on a form, Delphi handles the component creation automatically when the form is created. This article will cover the correct way to programmatically create components at run-time. Dynamic Component Creation There are two ways to dynamically create components. One way is to make a form (or some other TComponent) the owner of the new component. This is a common practice when building composite components where a visual container creates and owns the subcomponents. Doing so will ensure that the newly-created component is destroyed when the owning component is destroyed. To create an instance (object) of a class, you call its Create method. The Create constructor is a class method, as opposed to virtually all other methods youÃ¢â¬â¢ll encounter in Delphi programming, which are object methods. For example, the TComponent declares the Create constructor as follows: constructor Create(AOwner: TComponent) ; virtual; Dynamic Creation with OwnersHeres an example of dynamic creation, where Self is a TComponent or TComponent descendant (e.g., an instance of a TForm): with TTimer.Create(Self) dobeginInterval : 1000;Enabled : False;OnTimer : MyTimerEventHandler;end; Dynamic Creation with an Explicit Call to FreeThe second way to create a component is to use nil as the owner. Note that if you do this, you must also explicitly free the object you create as soon as you no longer need it (or youll produce a memory leak). Heres an example of using nil as the owner: with TTable.Create(nil) dotryDataBaseName : MyAlias;TableName : MyTable;Open;Edit;FieldByName(Busy).AsBoolean : True;Post;finallyFree;end; Dynamic Creation and Object ReferencesIt is possible to enhance the two previous examples by assigning the result of the Create call to a variable local to the method or belonging to the class. This is often desirable when references to the component need to be used later, or when scoping problems potentially caused by With blocks need to be avoided. Heres the TTimer creation code from above, using a field variable as a reference to the instantiated TTimer object: FTimer : TTimer.Create(Self) ;with FTimer dobeginInterval : 1000;Enabled : False;OnTimer : MyInternalTimerEventHandler;end; In this example FTimer is a private field variable of the form or visual container (or whatever Self is). When accessing the FTimer variable from methods in this class, it is a very good idea to check to see if the reference is valid before using it. This is done using Delphis Assigned function: if Assigned(FTimer) then FTimer.Enabled : True; Dynamic Creation and Object References without OwnersA variation on this is to create the component with no owner, but maintain the reference for later destruction. The construction code for the TTimer would look like this: FTimer : TTimer.Create(nil) ;with FTimer dobegin...end; And the destruction code (presumably in the forms destructor) would look something like this: FTimer.Free;FTimer : nil;(*Or use FreeAndNil (FTimer) procedure, which frees an object reference and replaces the reference with nil.*) Setting the object reference to nil is critical when freeing objects. The call to Free first checks to see if the object reference is nil or not, and if it isnt, it calls the objects destructor Destroy. Dynamic Creation and Local Object References without Owners Heres the TTable creation code from above, using a local variable as a reference to the instantiated TTable object: localTable : TTable.Create(nil) ;trywith localTable dobeginDataBaseName : MyAlias;TableName : MyTable;end;...// Later, if we want to explicitly specify scope:localTable.Open;localTable.Edit;localTable.FieldByName(Busy).AsBoolean : True;localTable.Post;finallylocalTable.Free;localTable : nil;end; In the example above, localTable is a local variable declared in the same method containing this code. Note that after freeing any object, in general it is a very good idea to set the reference to nil. A Word of Warning IMPORTANT: Do not mix a call to Free with passing a valid owner to the constructor. All of the previous techniques will work and are valid, but the following should never occur in your code: with TTable.Create(self) dotry...finallyFree;end; The code example above introduces unnecessary performance hits, impacts memory slightly, and has the potential to introduce hard to find bugs. Find out why. Note: If a dynamically created component has an owner (specified by the AOwner parameter of the Create constructor), then that owner is responsible for destroying the component. Otherwise, you must explicitly call Free when you no longer need the component. Article originally written by Mark Miller A test program was created in Delphi to time the dynamic creation of 1000 components with varying initial component counts. The test program appears at the bottom of this page. The chart shows a set of results from the test program, comparing the time it takes to create components both with owners and without. Note that this is only a portion of the hit. A similar performance delay can be expected when destroying components. The time to dynamically create components with owners is 1200% to 107960% slower than that to create components without owners, depending on the number of components on the form and the component being created. The Test Program Warning: This test program does not track and free components that are created without owners. By not tracking and freeing these components, times measured for the dynamic creation code more accurately reflect the real time to dynamically create a component. Download Source Code Warning! If you want to dynamically instantiate a Delphi component and explicitly free it sometime later, always pass nil as the owner. Failure to do so can introduce unnecessary risk, as well as performance and code maintenance problems. Read the A warning on dynamically instantiating Delphi components article to learn more...

The Scottish Parliament Building - Essay Example One of the major reasons of undertaking the project management activities is to add value to a project as well as to meet the set objectives in order to generate sustainable benefits from the project. According to Lewis (2006) the temporary nature of projects stands in contrast withÃ operations which are rhythmic, semi-permanent as well as permanent functional activities with the aim of producing products or services. In practice, the management of these two systems is often quite different, and as such requires the development of distinct technical skills and management strategies. Project management has been practiced since early civilization. Joseph (2003) stipulates that creating an appropriate project plan is the first thing a firm should adopt when undertaking any kind of project. However, many project managers fail to realise the value of a project plan in saving time, money and other related problems. There are a number of approaches emulated by project managers during init iating a project. Lewis (2006) stipulates that the major approaches include agile, interactive, incremental, and phased approaches. Regardless of the methodology employed, project managers must adopt careful consideration in order to achieve the overall project objectives. In order to achieve the goals of a project, it is paramount for project managers to be articulate in way they manage their teams. It is important to note that even though adequate financial resources are needed for a project to be successful, motivation of team members is an important aspect that project managers should not overlook. Effective motivation of human labour force, for instance through training and salary increment greatly contributes to completion of a project within the preset duration. The section below candidly discusses various aspects that led to the success of Scottish Parliament. Particularly, the section will cover optimal allocation of financial resources, proper planning of time and recruitm ent of skilled and experienced labour force as the main factors that ensured the success of Scottish Parliament. Factors that contributed to success in the construction of Scottish Parliament There are various factors that contribute to a success or failure of any project in progress. One of the major aspects that led to the success in the construction of Scottish Parliament was effective allocation of financial resources by the external donors. As stipulated by Dennis (2007) it is paramount for project managers to emulate proper use of financial resources so as to avoid vices such as corruption and frauds which are major hindrance of timely completion of a project. Based on the regular financial audit that was carried on during the construction of the Scottish Parliament, the possibilities of occurrence of misuse of funds were minimal. Effective time planning by the project managers is another vital aspect that contributed to the success of Scottish Parliament. Taylor (1999) depict s that failure by some project managers to properly manage their time, is a major factor that causes delay in the completion of the project. In this regard, managers who were responsible for the construction of the Scottish Parliament ensured proper scheduling of activities that were involved in the completion of the entire project.
