Domestic Violence Essay Example | Topics and Well Written Essays - 750 words

Domestic Violence - Essay Example Domestic violence has ruined the peace of the society. More and more people are falling into depression and anxiety with the grief of a lost or killed child, parent, sibling or spouse. Ethical dilemma to domestic violence: The ethical dilemma to domestic violence can be understood with the help of an exemplary case study. Let’s suppose that a woman who mothers three children gets hurt by her husband. She approaches a counselor who has newly started his career. The woman tells the counselor that she is physically abused by her husband. The counselor advises the woman to seek divorce and take her kids with her away from the husband. But the woman can not do that as she is afraid her husband would find and kill her along with her children if she attempts escape. In such a case, the counselor feels too inexperienced to give an informed suggestion. If he tells the authorities about this, his competence as a counselor would be suspected. If he gives a decision as he considers approp riate, this might take away four lives. Thus, the counselor is put into ethical dilemma because of the domestic violence experienced by his client. Likewise, several other points can be made from the same case study. Some common forms of abuses in domestic violence: Some of the most common forms of abuses people experience in the domestic violence are physical abuse, sexual abuse, social and emotional abuse, isolation, intimidation, discrimination, racism, threat and neglect. Each of these can be further divided into many forms of violence like punching, hitting, pulling, pushing, restraining, kicking and even hugging. Potential consequences of domestic violence: Consequences of domestic violence are very alarming. It causes homelessness. In order to escape interaction with the dangerous people, people put themselves into social exclusion. Many women who are offered physical, sexual, emotional or verbal abuse by their husbands take divorce get separated from them. This not only dist orts the whole family setup but also ruins the future of the children. Dysfunctional families, broken homes, depression, social exclusion and suicide are some of the potential consequences of domestic violence (Schweitzer, 2011). My stance on domestic violence and the basis for that: I hate domestic violence. I believe that domestic violence ruins the whole society by distorting the family system. I believe that in order to make a healthy society, people need to live in a strong family system. Almost all religions require their followers to live in nuclear family system. In a nuclear family system, everybody has well defined roles and responsibilities. A father earns bread for the family, while a mother nurtures the children. The children are perfectly brought up with the mutual efforts of both the mother and the father. The broken families harm the psychology of the children along with the separating partners, and they are not able to play a constructive role in the society. Applic ations that can be made to me professionally as a member of the Criminal Justice System: As a member of the Criminal Justice System, I can receive applications to make rational decisions and formulate policies that would address the individualistic concerns of the victims. â€Å"Professionals in criminal justice are called upon to enforce laws and also to implement policies. Policies can be formal or informal.† (Pollock, 2010, p. 154). Formal policies are formulated by the government’

Law and management - Essay Example Simply put, if you promise that you will do something for another person and in return, that person agrees to pay you something, then you and that person have made a contract. A contract can be in verbal or written form but the most important thing is that there would be an agreement especially between two parties. Likewise, according to the labour laws of many countries, both the worker and the employee are bound by certain statutory regulations that would ensure that no party will breach the agreed contract. Indeed, when a person has decided to enter into an agreement with someone, both parties should have a common ground of understanding of the nature of the contract they would be agreeing upon so as to avoid conflict and misunderstanding in the future. (ii) When another party has frustrated the contract entered into between the two involved parties, it can be said that this other part would have failed to owner the obligations stated in the contract in the long run as a result of difficult conditions arising during the course of the contract. Thus, according to information obtained online, the issue of frustration here is about the subsequent impossibility of the contract which may be a result of an unforeseeable event to both parties. In most cases, this event would be beyond the control of both parties such as death. No mortal being is able to stop death hence this becomes impossible for both parties to stick to the contractual obligations since it would be difficult to press ahead especially in the absence of a key actor in such a scenario. (b) The case involving Harry and Ian can be attributed to frustration of contract which in this case can be summed up as a legal termination of a contract as a result of unforeseen circumstances which may prevent that particular contract to achieve the intended goals or objectives. Whilst Ian had agreed to buy a motor vehicle from Harry, it is

Processes of Cultural Diffusion

Processes of Cultural Diffusion World has now become a global village. By global village what we mean is that everything is available to every person through the process of free information flow (Ascher, 2010). Globalization has brought everything closer and that has happened through cultural diffusion. Now to understand what cultural diffusion is, we first have to have a fair idea over what is diffusion. Secondly there is well defined process through which a culture is diffused in other cultures and makes it mark. This culture diffusion affects international business to the core because when we say that globalization have made its presence felt in the global economy, we see that it is there because of culture diffusion in different ways. This has also lead to come sort of cultural imperialism which we shall discuss in length in paragraphs to come. Culture diffusion happens when non material and material culture travels to another culture (Wise, 2008). How this happens is a million dollar question which needs to be answered correctly and to the point. To have a profound knowledge over how it happens we go to the basics of it which is culture hearth. Now culture hearth is a place where civilizations first began and then they spread to different areas. Nowadays culture hearths are considered to be in those countries which are well developed and whose culture gets diffused to other developing countries because they have to be in tandem with each other so to have a good and viable trade. If we talk by considering the present world and international trade, we see that this cultural diffusion has spread many cultural straits wherever they got a chance to get diffused. Sometimes this spread is so rapid that no one can find out its origin, timing and spread. There are two different ways in which a culture is diffused to another culture ; one is acculturation and another is Assimilation (Howes, 1996). Both are the ways in which culture is diffused in another culture. In acculturation what happens is that some cultural traits of strong cultures are being taken up by weak cultures like in ancient times we see that Spain had some cultural traits which are taken from Aztecs. Similarly if we see examples in the modern world we observe that a very common greeting hello is also a cultural trait which is being taken by many cultures as a greeting by default. Why that happened so? Because it has its roots in western world and as West dominated for the last two centuries, all the trade, rules and policies were being written and implemented by Western countries which influenced weak cultures to adopt the greeting and many other things which now we call globalization. On the other hand, another way in which a culture can be diffused is through assimilation. In assimilation what happens is that cultures are intertwined with each other in such a way that it is hard to distinguish between where its origin had been. Lets for example when Arabs came to Indian Subcontinent, the Indians had nothing than a piece of cloth worn up to their knees with an open jacket as their vests but Arabs brought a new culture of a full length suit of cloth covering whole body. Now after centuries the Mongols and the warriors from Afghanistan brought minor changes to the original dress which made people easy to carry, walk and most of all made it best attire which can be used for combat purposes also. End result was that the whole thing got assimilated with each other so quickly that there was little difference left between what people wear in Arabian countries mainly the natives of Arab Emirates and the people wear in subcontinent. It specially pertains to the dressing of men. Other thing which effects diffusion is the cultural barriers, time and distance delay and lastly physical barriers (Rauth, 2004). Cultural barriers includes things which are not acceptable to other culture at any cost for example Mc Donald came up in India with its different burgers mainly in beef but as Indians hold cow as sacred, they do not go for it so Mc Donald have to introduce veggie burgers instead of beef as local cultural barrier never allowed any assimilation or acculturization to take place. In time and distance delay, diffusion is hampered because time and distance which it would take to reach another culture would be more and then would become less futile for example Eskimos who live at poles, their cultures and way of living is different from us and still they are yet to have culture diffusion (Howes, 1996). Time and distance delay is somewhat linked with the physical barriers also which also helps in making things bad for cultural diffusion to take place for example t he terrain which is very tough to pass would obviously make things worse for people to travel hence making it hard to diffuse a culture or similarly a sharp weather change would also create a physical barrier for culture diffusion to take place as it would be difficult to take things from one culture to another as culture traits differ from each other or not even close to each other. That culture is diffused either in expansionary diffusion or relocated diffusion (Said, 1994). We have seen that expansionary diffusion have taken place in most of the places in world where West culture is being adopted by the elite and now it is being transmitted to the lower end of the population. This sort of diffusion is known as hierarchical diffusion in where the spread of a new culture takes place from top to bottom. Example of this is the coffee shops like star bucks, which had no concept in south Asia but they are brought by Westerners who came here for business purposes. They first inculcated the trend in elite and now it is being adopted by every person as it have has transformed many old kiosks for betel leaves and cigarettes into coffee shops. Similarly blackberries; many corporate customers have this gadget in their hands which is attracting other upper middle class people to have it too so to have some satisfaction. Other types include relocation diffusion which happen s when people take their innovations with them to a new place like for example Jews. Jews in Europe were really good in scientific knowledge and due to their astuteness they were being victimized and were sent to concentration camps. When after the world war they relocated themselves in different parts of the world, they went with their knowledge and innovations which brought a lot of prosperity around the globe. Another example of it can be AIDS which spread through relocation diffusion as disease is carried by one person who migrates to another society with having a different culture. Now as diffusion is discussed at length, we now see that whether cultural imperialism can be established through cultural diffusion? Yes to some extent I would agree to it because in international business when there is trade and goods flow from one place to another, it not only takes a new product across the borders but also takes its culture to another place. In other words level of diffusion depends on the factors discussed above and also on a culture being strong as to the culture where it is being diffused as being weak (Hobson, 2010). Like for example the trend of suits around the world, from where it came? It came and assimilated in our culture because it was being followed by a strong culture or in cultural hearth which is American and Europe and from there it diffused to all parts of the world. Mens formal suitings, as we all know, have such an importance that now if a south Korean business tycoon needs to do a deal with his Indian counterpart to open up a microchip factory in Delhi, they would be following their own business rules and formalities but their attire would be formal and would follow the strong cultures dress code which is to have a formal dress suit. Moreover the casual dress in China, a decade ago was not jeans and a tee shirt but now they have taken the affect of American culture as it diffused into their society but why? Because more than 70 percent of chinas trade is bound for America so Chinese have adopted some practices of American culture which shows us that yes there is diffusion of culture but that does not proves cultural imperialism at any point; people went towards tee shirts and jeans because they were easier to handle, according to the young generation, as compare to traditional safari suits for men and traditional Chinese for women. Apart from this, cultural diffusion does not reflect cultural imperialism for example whole world is following more or less same accounting principles so the rules of debit and credit are same so to imply that it is a product of a particular nation or it is a part of any culture would be a gross mistake. Yes its true that methods of accounting were first brought up by Chinese but significant changes were made throughout.

Pearl Buck: The Bridge Builder :: essays research papers fc

Pearl Buck: The Bridge Builder Humans fear and loathe that which they do not understand. This fact has been true for ages and still exists today. Fortunately, there are people such as Pearl Buck. People like her see the injustice in this simple fact and work to break down the walls of separation between other people. She took on the seemingly impossible task of building a â€Å"bridge† across the Pacific Ocean to China from America and broke down many walls through her writings, doing a great service to many. Biographical Information Pearl Sydenstricker Buck started her eventful life as Pearl Comfort Sydenstricker in Hillsboro, Virginia on June 26, 1892. Important events took place before this that made her birth even more special than a normal birth. Theodore Harris says that Buck’s mother Carie married a man named Andrew Sydenstricker, a Presbyterian missionary in China. The couple had a daughter and raised her there. When the child was four years old, she and her mother contracted cholera. Only the mother survived (18). Buck was born two years after this tragedy while the family was on hiatus from their mission work in China. When Buck was three months old, they returned to Chinkiang, China. According to Theodore Harris, Buck spent her whole childhood there with many Chinese influences. Wang Amah, a Chinese nurse, assisted her mother. She played with Chinese children and lived in a house along the Yangtze River (30-31). These influences later played an integral role in Buck’s success as a novelist. The Encyclopedia Britannica Online says Buck’s early schooling was received in Shanghai. Later, she returned to the United States and graduated from Randolph-Macon Woman's College in the year 1914. After graduation, Buck went back to China and became a college professor in Nanking (1). According to Dr. Bette Reagan, Pearl Comfort Sydenstricker married John Lossing Buck, also a missionary in China, and became known as Pearl Sydenstricker Buck. The ceremony took place in China in 1917. During their marriage, the couple had a daughter named Carol. While delivering the baby a uterine tumor was found in Buck, forcing her to have a hysterectomy. This left her with no possibility of bearing children again. To add to the pain of this blow, Buck later noticed that their only child was mentally retarded, suffering from a disease called PKU. The family decided to return to the United States to place Carol in a care facility in Vineland, New Jersey (1).

History of Filmmaking Essay

The main problem with assigning national identity to films is the enticement to pick movies to fit the premise. Hardly ever does a director present any significant standards by which particular films have been chosen for analysis. To give a specific example, one merely has to consider the Japanese instance of Kurosawa Akira whose movies regularly received positive commendation both overseas and in domestic ratings, yet several of Akira’s films remain difficult to get to to the mainstream Japanese viewers. Another problem for assigning national identity to films is the relative lack of engagement with modern social and political concerns or conditions. It’s pretty evident with Australian films (Nadia Tass, Malcolm and The Big Steal). Australian movies do not create a point of plainly and continually pondering over national identity. They take the method of conveying tales in a local context and allowing inquiries of national identity work out themselves in the backdrop through the working of their diverse and unlikely narratives. The issue of â€Å"what does it mean to be Australian? is responded upon by illustrating various Australians, in unusual situations, with several problems. In my humble opinion, studies with this stature helps shine a ray of light on how and why the nation pass on a meaningful masterpiece in their local perspective, the focal point should be on reputation within the related/state/area as the major norm for selection.. Whether they have established vital praise at ‘key film festivals’ is another material connected to ‘art house’ films, which is frequently not a fine statistic of admired appeal and consequently not a superior indicator of community communication.

The first recorded use of rammed earth was by the Babylonians in 5000BC. Parts of the western portion of the Great Wall of China 300BC are built of rammed earth. Almost every European country has a history of rammed earth construction but is usually a material associated with arid areas. 780-1850 Rammed earth experienced popularity in the USA until mass production of fire bricks and sawed lumber became readily available. These materials were now favoured for being more elegant and modern than using rammed earth – or â€Å"dirt†. However during World War I and the Great depression, supply shortages prompted a return to Rammed Earth. Rammed Earth remained fairly unpopular then until the 1970’s when it began to be rejuvenated by the environmentally conscious.Despite Rammed Earths extensive use throughout history, its use is still not so popular within the UK. Reason for this is largely due to architects/ Builders not knowing enough about the material and sticking to the familiar concrete, timber and brick ways that they know, rammed earth can often also be perceived as having cruder finishing and not in keeping with the clean-sharp lined finished which are so often preferred in today’s archi tecture- Though with the appropriate shuttering clean finishes can be achieved.Building with rammed earth is considered to carry greater risk and uncertainty, the material is yes, more suited to arid climates, but even in arid climates modern method of construction using rammed earth are being continually tried and tested e. g. in Australia. Rammed earth is a perfectly viable and good material to be used within the UK – there is a need to get past the reluctance to use and experiment with it more here – the climate presents a challenge which can be won in innovative ways. [pic] The Use of Rammed Earth within the UKThings which prohibit the wider use of Rammed earth within the UK †¢ The longer than average period needed for construction. †¢ The formwork and Labour costs. †¢ The climates high humidity climate – Moderate external temperatures. †¢ Concerns which are had about the careful detailing which can be required. †¢ Poor thermal resis tance – The need for external walls to require additional insulation. †¢ Not all soil types are appropriate importation of soil for a rammed earth construction will significantly detract from its environmental credentials. The Quality control required for rammed earth constructions is quite high. †¢ Moisture movement can be caused by high clay content. †¢ The UK has few modern examples of rammed earth buildings – relatively untested in this climate – comparative to other countries. †¢ There are currently no UK codes of practice on rammed earth construction. †¢ Adding cement stabilisation can compromise its attributes as a sustainable material. †¢ It can be difficult to find insurance for rammed earth construction. It needs to be kept dry during construction which can result in the need for temporary roof structures. After construction this presents the needs for overhangs or on exposed sights structures to protect from prevailing el ements- can compromise aesthetics. †¢ People hungry construction. †¢ Some more high profile examples of rammed earth building in the UK have experienced problems e. g. the Eden project- over hangs were not big enough and the splash back of rainwater has eroded some of the facade. Reasons why rammed earth would be chosen over other materials It distinct appearance. †¢ Natural and readily available. †¢ It has a low embodied energy. †¢ Rammed earth is hygroscopic – due to high moisture mass – it will regulate humidity. †¢ Post demolition – unstabilised earth is reusable. †¢ Supports sustainable practices by using local soils. †¢ High Thermal mass – though the extent of which has yet to be quantified. †¢ Airtight construction is achievable. †¢ It can be considered a traditional form of construction. †¢ Modern methods have and continue to be widely tried and tested overseas. An integrity of building is exp ressed which is often lacking nowadays. †¢ Expression of cultural conditions. †¢ Acoustic properties- its dry density (pd) is typically 2,100 kg/m3 therefore the weighted sound reduction index (Rw) would be 58. 3dB [1] and thus more than satisfies Building regulations (2000), Doc E Resistance to the Passage of Sound. Other considerations when Using rammed earth Rammed earth is hygroscopic, therefore external cladding systems must be vapour permeable to allow for evaporation.Important for unstabilised walls and less so for stabilised walls where stabilising agents will impair breathing, still it is better to consider vapour permeable solutions for both instances to reduce chances of condensation build up on the inside face of insulation. Water resistance the need to keep the structure dry post construction is done in various ways, large overhangs, plinths upon which the wall is constructed, rendering or cladding to the facade- these options will affect the structures sustai nability, look and thermal mass.A comparison between the calculated U-values for both ‘conventional' masonry and Stabilised rammed Earth wall designs [pic][2] Rammed earth as a sustainable material CO2 Emissions are greatly reduced with the use of rammed earth, as opposed to cement which due to the need for burning limestone produces CO2 contributing about 10% of the global CO2 emissions. Rammed earth taking soil from the site not using a stabiliser is the most sustainable method; however the addition of a cement stabiliser is common practice and considered to reduce considerably the risk and uncertainty, cement is used making up 6-7% of the mix.The embodied energy is low- its inherent recyclability and reduction of CO2 during the structures lifetime, high thermal mass and low operating costs. If the clay can be sourced from site, and is suitable then it eliminates all transportations cost. If the clay is not so suitable, then a stabiliser of cement can be added. If the soil o n site is not at all suited for a rammed earth construction then clay can be transported to site- however both of these options will compromise the environmental integrity of the building, the latter of which doing so quite considerably.Also due to the need for rammed earth to be kept dry at all times during construction there can be a need for temporary roof structures to keep the rain away, this will therefore impact its sustainability. Depending also on what type of shuttering is used can lead to waste, for e. g. timber shutter although can be reused, its reuse is limited as it will become saturated from the moisture in the clay. Thermal Performances, Rammed earth has a high thermal mass – walls will naturally regulate both the internal temperature spaces, and can also regulate the temperatures of external spaces such as courtyards.Energy required to heat and cool a building can be greatly reduced if rammed earth is designed into the heating system, however the UK requires the addition of either internal or external insulation, this aside from affecting the aesthetic of either facade it is fixed to, will compromise the thermal mass of the adjacent space. Structural Performance, whilst the structural strength and stiffness is compromised with increased waster content, if designed correctly and waterproofing measure taken then rammed earth is perfectly capable of acting as a load bearing structure.Rammed earth which is imported in not only contribute to the cost and environmental issue of transportation, it also leaves a scar on the landscape as it is being taken from elsewhere, e. g. a quarry, even if this is later turned into some sort of nature reserve it is still leaving a permanent change to this landscape. Insulation – in the UK there are few examples of rammed earth combining insulation, most contemporary walls are unclad, but there is an increased need for insulation to be used in conjunction with the thermal mass of the walls. |Advanta ges |disadvantages | |External Insulation |Walls protected from weathering |Loss of characteristic appearance | | |Exposed thermal mass internally |Loss of thermal mass externally- which is | | | |sometimes used to regulate temperatures of | | | |spaces such as courtyards | | | | | |Internal Insulation |External appearance is maintained |Loss of available thermal mass. | | | |Internal appearance compromised | [pic][3][pic][4] Weather protection †¢ Weather needs to be drained away from walls †¢ Construction upon raised footings †¢ Avoidance of sites vulnerable to flooding †¢ Protecting wall from rain using adjoining elements e. g. roof overhangs †¢ Allow evaporation of moisture from walls †¢ Onsite which are considerably exposed there is a need to consider rain screen cladding or render. Construction Week AimsThe aim of the work we did within the workshop was to question the building processes as a whole, by means of both small and large scale prototypes , to push the presumed limitations of a material and its formwork, to not just accept, that rules have been predetermined, but to push for innovation. As we studied, the idea of the â€Å"builders yard† allows for just this, meaning a material can be taken and experimented with, in a specific location which possesses the same limiting factors as the actual site e. g. Climate and resources, and test particular means of creating the desired construction before doing so, it is a hub for construction in the area- encouraging risk by means of experimentation rather than out casting it.The advantages of such an idea are that when a material can be experimented with it allows for greater understanding and judgment of its limitation- rather than acceptance of existing limitations, and therefore systems of constructing and spatial relationships can be explored. The community have a personal knowledge of the neighbourhood its character and needs, they are given the power to modify and contribute to it, their personal attachment means, as workmen they have a continued responsibility to the changes which occur with building in the area as well as maintenance of them. The people who work together within the builder’s yard understand and achieve better quality meaningful results; the workmen are uniquely and specifically educated, and the buildings produced are, unlike much of the current construction possess a humane quality, a warm character.The focus on the act of making allows for and evolution and a subsequent greater understanding of everything involved in the construction and about the materials. By making the rammed earth wall within the studio we were pushing the boundaries of predetermined limitations, re-examine the architectural production of rammed earth, and coming up with our own unique response. We explored the possible use of fabric formwork by means of making and testing prototypes on a small scale and then on progressively larger scales we s ee how it uniquely responds to specific methods thus learning learn how the material and structure can better work together, creating a successful wall with fluid innovative shapes, with lower embodied energy.Whilst making our wall every element was specifically made and tested and altered, until the best result were achieved, for example we experimented a lot with the sizes of our buttons, trying to get them to sufficiently restrain the wall –without damaging it when removing them, we were fortunate to stumble upon a size which not only did the job we required but more. This scenario is similar to what happens in the builder’s yard; it is this experimentation –and risk taking which leads to the discovery and sometimes unexpected discovery of innovative solution and inventions. There can be other factors, such as keeping cost down driving the invention of new materials and components. [pic] [pic] [pic] Prototype IAs a group did we met with Roland for a quick bri efing on what direction we should take for our rammed earth wall, he suggested that we should first sit down together and come up with some ideas and sketches to make some prototypes, and that we should also sort out the earth so that it would be ready for when we begin construction. We discussed some ideas about what sort of shaped wall we would like to achieve, including some over ambitious ideas of constructing the walls then flipping it! We agreed we wanted to design a wall to incorporate a curve, a variation in thickness of the wall from bottom to top. We divided into three groups and set about coming up with a design each and building a prototype to text these ideas. Once the earth and fabric had been sorted we each returned to our prototypes, and began to each work out and start making our frame work. Our group decided to make a framework by cutting a .Semi Lunar shape to incorporate some variation in thickness throughout the wall the . Assembling a frame to which we could pi n the fabric to at intervals after each period of . Ramming. The Idea was that one side of the wall would be taut and quite flat and the . other we would periodically place round ties to restrain the wall and create an undulating shape to it. [pic][pic][pic] Basic framework Difficulties with attaching fabric and supporting threads Excessive budging over buttons. Issues highlighted by Prototype 1: †¢ First of all we needed to add further supports as the structure was not as stable as hoped. Tight spaces need to re-think to consider a pneumatic rammer fitting inside the formwork/ framework. †¢ The way the formwork was constructed some of the supports hindered the pinning of the fabric to wood. †¢ The button and tie system we used was not as successful as we hoped- we believed this to be down to the size of the wooden buttons being too small in diameter , which resulted in them become stuck under the overhanging rammed earth and were difficult to remove without causing d amage to the wall. They did not restrain the width of the wall much either, this was also partly due to us leaving the thread too long. Also initially we put on the ties without the wooden disc which resulted in a serious overhang. When we were ramming the earth we did so by hand, using some pieces of wood with flat ends, the highlighted another problem-as due to the way the framework was constructed we had a piece of wood running across the top we made manoeuvring a piece of wood let alone a pneumatic rammer difficult. †¢ Despite having made a definite shape in the base board, to influence the shape of the wall- it in reality had no effect as the fabric took its own shape. †¢ The need to be taught correctly how to mix the earth and test it. †¢ The need to not put too much earth in at each layer as the lower down parts were not getting properly compressed [pic] [pic] Prototype IIThis prototype consisted of 3 wooden sides and a wooden base cut with a curve the fabric w as then pinned to the front and around the curve – the idea being that pinning the fabric to the curved base would create a curved facade. However this prototype was pretty unsuccessful – it suffered structural issues and was not strong enough to withstand the pressure of the rammed earth inside, as it was simply nailed together. The fabric also failed to restrain the form of the wall and budged with little shape. Another issue was that as this prototype required a wooden base beneath it, -not so practical! – In reality this would be likely to make the wall less structurally sound- and would be pretty impossible to remove as a rammed earth wall is extremely heavy. In conclusion this wall was a failure. [pic] SOIL TESTING [pic]Compressing the soil then dropping from arms length away. EARTH PREPARATION Whilst making the first prototype our earth was not of the correct consistency – which resulted in our wall crumbling a bit. We had used the earth which we h ad moved indoor on day one – we added some water to the clay- thinking this would help the earth-stick and compact better. It wasn’t until Rowland came on the 3rd day and was able to tell us immediately, the mistakes we had made, and then showed us the correct for mixing, preparing and testing the earth. We broke down our prototypes returning the earth to the pile and also broke down the previous year’s pillars so the soil could be recycled. [pic] [pic]At first we used the pneumatic rammer to break down these pillars- this was also our first encounter with using the pneumatic rammer, so we learned some general things about using it – safety precautions with turning it on and off, how it must be held, and despite having identified issues of safety in our risk assessment – not many precautions were taken – wearing of safety clothing/boots/goggles. We then began to break it up further using shovels and spades- a lot of dust had been created by this process so we got buckets of water and using bottles threw water over the earth and clay. Once it had all been broken down we began to mix it altogether whilst adding water at the same time. The earth needed to be constantly moved and shovelled – thoroughly so that it’s would be of the same consistency throughout. When the appearance of the mix changed and seemed to be getting close to what we wanted – it looked darker and less dry and dusty, we began to testing it.To test the soil we picked up a handful – squeezed it tightly between both hands, then holding it at arm’s length away from the body- arm held straight – dropped the earth from this height and if it broke into 3 main pieces then we would know that it was ready to ram. It took several testing remixing / adding extra moisture attempts before we did get the earth just right. We also needed to continue testing the earth as over the days it could dry out – so we regularly m ixed the soil and tested it adding water when necessary. PROTOYPE III On the third day, when Rowland came and saw each of our sub groups prototypes. He was able to give us feedback, and give us some explanation to why some things had occurred which we hadn’t expect. In our prototype the spacing of the buttons presenting some issues, as did the several elements of the framework.As a group with the help of Rowland we began work on another prototype, again involving a curve, this time a more defined one with the hope it would have an impact on the shape of the wall. This time however we were to make are formwork as minimal as possible. At first we used just two pieces of wood placed either side of the fabric, and at the other end we used thread to sew it up. Sewing a few inches at a time, to make manoeuvring the pneumatic rammer easier. It was then decided we would place a piece of timber at one end-to achieve a flat surface. We spaced the buttons further apart from each other a nd more evenly spaced. We made planned the wall so it would be 1. 5m long but due to the excess budging which occurred it was approx 1. 2m in length and 1. m high, we positioned 3 rows of 2 button / thread equally spaced. Also when with the previous prototype when we placed the threads simply did so and then proceeded to ram the earth, however this presented a problem when it came to trying to remove then- it was really not possible to remove then without serious damage to the wall occurring. So to avoid this problem, we used some plastic tubing, through which the threads would sit, this would allow use to remove the threads and re use them again within the same wall. When using these we had to be careful whilst ramming and not hit or cause excess pressure on the threads as they could break or bend. [pic][pic][pic][pic]Tubing covering Threads Button buckling under pressure sewing of one side wooden panel at other side When ramming the wall we added a few inches of earth at a time, m aking sure that it was even first then rammed it until it compressed down and then added the next layer- it is quite a long process. It was necessary to ram the edges first keeping the rammer moving at all times moving from the edges inwards, ramming around the thread/tubes until it was at a point where enough earth was above the thread it was safe to ram on top. This prototype was largely successful the few things were again highlighted which we would resolve within the final piece.Again something highlighted by the buttons; was that because of the way we made them- 75mm diameter, bigger than in the first prototype, but they were made using thinner wood than before and due to the pressure of the rammed earth above the buttons- they had actually buckled and bent. This however was a positive thing as they both allowed them to be removed easily-and without damaging the wall, and also created a nice effect on the wall aesthetically. [pic] [pic]Final Wall We had been quite successful in our final prototype so our intention was pretty much scale this up for our final wall. We began by cutting a piece of timber to create a hole sized 1. m by 300mm, to which the fabric which we had cut 4m x 2. 2m was then pinned to the underside of the piece of wood- to keep it in place and restrained during ramming. We used on piece timber 2m x 300mm on one end which we nailed to the fabric and base board at One end, to achieve our flatter surface, and on the other end, we used the method of sewing to create a more curvaceous crafted appearance. The fabric was sewn at intervals, approx 30mm at a time. The Earth which we had prepared as outlined- in Earth preparation, had 2-3 people constantly working to keep its consistency and moisture content even, and at interval shovel it into the structure.Earth was filled and evened out at approx 15mm at a time and then rammed and compressed down. Two people were needed to ram at all times, with 2-3 supporting people, holding material, and als o as we got higher and higher- needed to help hold and steel the pneumatic rammer as it became more and more difficult with height. The process of ramming would begin once the earth had been levelled, begging at edges and moving systematically towards the centre, taking care when approaching the plastic tubes containing the treads and attached to the buttons- directly ramming above them could cause them to bend and distort the shape and support they gave.At 350-400mm vertical spacing’s buttons and threads were attached, piercing the fabric with a knife to create a hole through which the threads within their plastic tubes were placed, to the end of these on the exteriors of the fabric were placed the buttons, which were had cut 75mm in diameter using a piece of thin piece of wood approx 7mm thick. These buttons, along with supporting washers and bolt could later be removed along with the actual thread, and reused. The buttons etc were placed at 300mm horizontal intervals. The Spacing was determined from out prototype as the best spacing to create enough support, least uncontrolled bulging, without over restraining the structure.This added the restraint of the wall, the crafting of curvaceous shapes and ease of removal of components. The making of the wall comprised of adding earth the earth then ramming and repeating this process until 350-400mm height was achieved, then addition of the threads and buttons and repeating again until we reached 2m height. All the while we also were constantly maintaining and controlling the earth consistency by turning, adding moisture and regularly testing as explained earlier. As we reached higher –more people were required to aid the steering and supporting of the pneumatic rammers, but as we had less soil we were able to sacrifice people from this.In reality on a larger scale project this may not be a solution that could work, however as our means of reaching higher and higher was a series of standing on chairs and then tables and even some risque chairs on table, this would definitely not happen on a real site as it would most certainly be violating all sorts of health and safety rules, adequate scaffolding would be used and people the people working on ramming and earth maintenance would remain constant. Once the wall had been rammed until the top and almost all of our soil supply had been used, we were able to take down the fabric formwork, which took comparatively little time to assembly and construction. We unscrewed the buttons removing them which care†¦ just in case†¦. hey had in the same way with the prototype buckled under the strain and had curved round so once removed left a beautiful perfectly ball like shape, and we quite easy to removing, causing no damage to the structure, after that we cut the fabric to remove it, it was very easy on the side with the wood, coming away leaving a very flat surface, on the other side, some more care was taken not to damage the impri nt of the sewing, though more care was taken than was probably needed- the deceptively soft look of the wall made one think it might just crumble away, which was of course not the case, it was more delicate at edges such at the ends that were sewn, but very durable. The only part of the wall which really presented any issues when removing the fabric was the bottom, of course the fabric pinned beneath could not be removed, but as the wall had bulged over the wooden base trapping fabric below, we had to cut around the bulges leaving fragments of the fabric stuck beneath- it was just impossible to remove, but they were not noticeable after edges were trimmed, and neither affected the strength or overall appearance of the wall.The only implication if would have in real building sites would the amount of fabric salvaged from each construction would be less , and whilst it could be reused, the size of fabric over time would shrink and shrink. [pic] The changes to the design we did make fr om our previous prototype were: †¢ We discarded the idea of incorporating the curve as in every attempt so far had been unsuccessful, having no affected on the shape of the wall. So we simply cut a straight rectangular shape into our baseboard. †¢ Rather than having two pieces of wood either side of the fabric then bolted together and the piece of timber then placed inside the piece, we used the one piece of wood at one end and attached the fabric to that. As the wall was going to be longer we would be using 3 button / threads per row and having 4 rows We stuck with the method of sewing up the other side as it had been quite successful in the last wall, however in the final wall throughout the process of ramming it became apparent that it was leaning quite a bit particularly at the top of the wall- as can be seen in the final photograph. [pic]FINAL WALL [pic] Conclusion During the course of construction we learned a lot about building with rammed earth. Before this week I believed that building the wall would be a lot more complicated than it actually is, and I found it fascinating at how much could be achieved with some Fabric, thread, very little wood, some buttons and some earth!It was interesting the affect that the stitching, buttons and wood had on the wall- a very unique finish could be achieved and the structure was so strong and solid despite of it looking much like a giant cushion. The first thing we did in preparation for construction week was our risk assessment- however despite highlighting various precautionary measures we should take – in reality we took almost none. However I think that the risk assessment was still quite accurate in assessing the risk it was wrong not to observe the suggested measures. We did at times wear goggles when the dust simply made it impossible to see what we were doing when ramming, and we did take great care when using the ramming equipment as its use carried the most danger. But in the end I think fashion won out over the use of goggles, masks, boots and gloves.The Buttons which we used were probably the most successful thing that came out of our construction week. Although by complete accident. Because we had used a thinner piece of wood for our buttons in the final prototype when we rammed the wall – the buttons buckled under the pressure and at first we thought that this was another failure, but in the end it turned out this worked in our favour- they were easy to remove without damaging the wall, but also gave a very clean nice rounded indentation- success! [pic][pic] [pic] The Rammed Earth wall and construction methods we used differs from the conventional way in which a rammed earth wall is made by using fabric as formwork as opposed to wood or metal as is the norm.Within UEL the students and staff are pioneering the use of fabric formwork with rammed earth – which has otherwise been left unexplored as a method. In previous year in UEL students and staff h ave also experimented with fabric to make rammed earth columns. The use of fabric in other construction methods such as concrete has been successful, well received and used more and more in various new and innovative ways. The wall which we built was largely a success in all aspects of shape, height, strength and texture. Making it very possible that this project, could lead the way for further use of fabric formwork within the field of rammed earth constructions.It has been proven successful and there is no reason that this method could not be adopted as a viable means of construction in mainstream rammed earth constructions. The Reasons why constructing a rammed earth wall using fabric is better than current method are numerous: ? Sustainability ? The use of low embodied energy rammed in conjunction with fabric resulted in an ultra ecological combo. ? The fabric can be used and reused, as can the buttons and threads ? Beauty ? Sculpted texture created when using fabric can be quit e desirable, and will be depending upon specific fabric choice ? The Positioning of the buttons will also impact upon the finished appearance. The effect achieved with our wall was that of a large cushion As there are fewer limitations on the size of fabric which can be used as there are when using wood – where marks from joints are unavoidable. ? Rapid construction and deconstruction of formwork. ? Fewer things are needed to construct a wall when using fabric, so in principle this method could be used in obscure locations where communications are poor, as transpiration would not pose as much of a problem as it would if using heavy –bulky formwork, provided of course the earth could be found on site. ? Expense –Fabric is less expensive than conventional formwork, fabric formwork is approx 1/25th [5] the cost of dimensional lumber ? Less Weight- weighting approx 1/300th[6] of rigid formwork. There are too, reasons why using fabric formworks may not be favoured. ? Manpower The way in which we constructed our wall required people to do various different things simultaneously, ramming, holding the fabric to keep it tense, shovelling the earth into the wall, turning the soil to maintain moisture consistency. In general at any one time we required 7-8 people so building on a larger scale could present issues of number of people required. Although alternative method of turning the soil or holding the fabric could be adapted. ? Appearance ? The fabric restrained appearance may not be appropriate to the design and desired look. ? Height restrictions ? Whilst there are no specific height restrictions associated with fabric form work- it is an aspect of this construction method- yet to be explored fully- our wall was just less than 2m, what would happen when the height would be increased?Would there be significant implication affecting thickness of the wall? Budging is not as controlled with fabric as with wooden formwork. One of the great things I s aw from our construction week was working together with a set of people for one week for a common goal- we achieved so much, learning from each other sharing ideas and testing them, One can really see how this is in some small way how the builders yard idea must function, and therefore I would believe it to be a really successful idea. If a small group of people in one week can create this unique rammed earth wall- then communities of people working together on projects of greater long-term significance to them i. e. heir homes their neighbourhood the places they will spend their lives, with such vested interested interests, and working on larger scales over longer periods should be creating all sorts of innovative building techniques, materials and components.
