Sustainability Practices In The Turkish Construction Sector Environmental Sciences Essay

Abstract. The Turkish building services bunch is the thirteenth largest in the universe in footings of exports and has demonstrated really high growing of 63 % in international projects. Katsarakis et Al ( 2007 ) split this bunch into two parts and call them as the lower-quality domestic-only set of houses and the higher choice international houses. On the domestic side, there are more than 30,000 active local houses ( TCA, 2009 ) . On the international houses ‘ side, there are over 140 houses, 23 of which are among the 225 largest building companies worldwide in footings of abroad activities per ENR 2008 listing. This degree of activity, peculiarly the international activity, places upon the Turkish building bunch a duty to guarantee good working conditions for all its employees and to play a polar function in continuing the environment, extenuating bing polluted countries, salvaging natural resources such as H2O, energy and natural stuffs. This paper examines, through a liter ature survey, the current degree of sustainability apprehension in the Turkish building sector. The survey concludes that the degree of sustainability apprehension and hence its execution is unstructured, bit-by-bit, and inappropriate for the prima regional function that the Turkish building bunch will play. The paper concludes that a more holistic attack is required, which will necessitate political policy and larning from best pattern from other states and immensely increased instruction and preparation in the constructs of sustainability. Keywords: Construction bunch, policy, scheme, Sustainability, Turkey 1. Introduction Sustainability is more and more going a cardinal concern of every person. It is a concern that has grown out of a wider acknowledgment that lifting populations and economic development are endangering a progressive debasement of the Earth ‘s resources per CIOB ( 2009 ) . The building, care and usage of edifices have significant impact on our environment and are presently lending significantly to irreversible alterations in the universe ‘s clime, atmosphere and ecosystem. Endeavoring for sustainability is a uninterrupted procedure of alteration. The building industry is confronting ever-increasing demands to better its sustainability public presentation. Sustainable development applies at the political and macro economic degree to communities. The clients and stakeholders of the building industry demand betterments of its patterns and its public image. Karacay ( 2003 ) stated that the epoch of â€Å" more production-more ingestion † is over and a great trade of accent should be to sustainability for uninterrupted sustainable economical growing and development. Sustainable building is a manner for the building industry to travel towards accomplishing sustainable development, taking into history environmental, socio-economic and cultural issues. Specifically, it involves issues such as design and direction of edifices, stuffs and edifice public presentation, energy and resource ingestion – within the larger orbit of urban development and direction. In this paper, sustainability of the substructure undertakings will be concentrated on. Recent publications related to sustainable building in the context of Private Finance Initiative ( PFI ) route undertakings ( AkbA ±yA ±klA ± & A ; Eaton, ( 2009a and B ) ) and sustainable substructure developments in the instance of Public-Private Partnership ( PPP ) ( Eaton & A ; AkbA ±yA ±klA ± , ( 2008 ) ) are available. 2. Sustainability Sustainability, as stated by Werbach ( 2009 ) , is more than â€Å" green † ; it is concern agencies, above all, guaranting that the concern thrives in the long term and takes into history every dimension of the concern environment. Sustainability is the concern with long-run profitableness. Sustainability needs a scheme behind that includes all the supply concatenation, top direction engagement and support ; and it relates all the concern organisation. We are in an epoch that the Nature and the equilibrium in the Nature that will govern and regulate the developments in our industry. We will be concerned more than of all time in the value adding in the building concern that will be a combination between sustainability ( societal, economic, environmental and cultural ) , efficiency and effectivity. In Werbach ‘s ( 2009 ) words, â€Å" Until the 1980 ‘s concern leaders used the word sustainability to intend a company ‘s ability to increase its net incomes stea dily ( Werbach, 2009 ) . Sustainability represents the best technology attack of all – the acknowledgment that no undertaking exists in a vacuity, but in a societal and natural context that affects the undertaking and is affected by it in bend. If we take this holistic position of technology, which involves esteeming the natural and human environment in the design, building and operation of our undertakings, we find distinguishable benefits in footings of quality, proficient inventions, and long-run societal, economic and environmental returns ( Tanal ( 2004 ) ) . Harmonizing to Werbach ( 2009 ) , a sustainable concern means a concern that can boom in the long term. Brundtland Report ( 1987 ) , besides known as Our Common Future, alerted the universe to the urgency of doing advancement toward economic development that could be sustained without consuming natural resources or harming the environment. The study was published by an international group of politicians, civil retainers and experts on the environment and development, and provided a cardinal statement on sustainable development specifying it as â€Å" development that meets the demands of the present without compromising the ability of future coevalss to run into their ain demands † . The study besides suggested that equity, growing and environmental care are at the same time possible and that each state is capable of accomplishing its full economic potency whilst at the same clip heightening its resource base. Furthermore, in the same survey it is reported that accomplishing the equity and sustainable growing would necessitate technological and societal alteration. In stead to this fact, Sage ( 1998 ) stated that sustainability necessitates the development of enlightened establishments and substructure and appropriate direction of hazards, uncertainnesss, and knowledge imperfectnesss to guarantee intergenerational equity, intergenerational equity, and preservation of the ability of Earth ‘s natural systems to function world. As defined by Chaharbaghi & A ; Willis ( 1999 ) and presented in a study on sustainability by FIEC ( 2005 ) , sustainable development is a construct based on a construction which stands on 3 pillars, viz. economic, societal and environmental. This inter-related model is shown in Figure 1. Fig. 1. Three pillars of sustainability ( Chaharbaghi & A ; Willis ( 1999 ) in â€Å" Managing Knowledge in the Context of Sustainable Construction † ITcon Vol. 11 ( 2006 ) ) 3. The building industry and sustainability Sustainable building can be defined as a building procedure which incorporates the basic subjects of sustainable development ( Parkin ( 2000 ) , Chaharbaghi & A ; Willis ( 1999 ) , Sage ( 1998 ) ) . Such building procedures would therefore convey environmental duty, societal consciousness, and economic profitableness aims to the bow in the reinforced environment and installations for the wider community ( Langston & A ; Ding ( 2001 ) , Miyatake ( 1996 ) , Raynsford ( 2000 ) ) . Companies are the cardinal elements of modern economic life and they have an of import function in conveying about the alterations needed for sustainable development. Harmonizing to Wilson ( 2003 ) â€Å" corporate sustainability is a concern attack that creates long term stockholder value by encompassing chances and pull offing hazards deducing from economic, environmental and societal developments. While corporate sustainability recognizes that corporate growing and profitableness are of import ; it besides requires the corporation to prosecute social ends, specifically those associating to sustainable development such as environmental protection, societal justness and equity and economic development † . Werbach ( 2009 ) argues that, if imagined and implemented to the full, sustainability drives a bottom-line scheme to salvage costs, a top-line scheme to make a new consumer base, and a endowment scheme to acquire, maintain, and develop originative employees. The three pillars or as named by Fiksel ( 2001 ) , the â€Å" ternary underside line † , economic prosperity and chance societal equity and quality of life and ecological resource saving represents sustainability as an organisational committedness to accomplishing competitory advantage through the strategic acceptance and development of ecologically and socially supportive production procedures, merchandises and services and advanced human resource direction patterns. ( Dunphy et al ( 2003 ) ) . For those organisations prosecuting sustainability, it is cardinal to their corporate schemes and a critical ingredient in how they assess their effectivity. A survey by Dunphy ( 2004 ) states that â€Å" sustainability consequences from activities which extend the socially utile life of organisations, heighten the planet ‘s ability to keep and regenerate the viability of the biosphere and protect all life species, enhance society ‘s ability to keep itself and to work out its major jobs, keep a nice degree of public assistance for present and future coevalss of humanity † The building industry and the reinforced environment must be counted as two of the cardinal countries required to achieve a sustainable development in societies. It is a widely known fact that, the edifices are responsible for over 40 % of all the waste produced in the European Union. In developing and passage economic systems, building has a immense part to the Gross National Product ( GDP ) ; but this has to be done in a more sustainable mode while bettering the quality of life and making wealth. However, sustainable building adopts different precedences in different states. There are widely different positions and readings between developed and passage and developing states. The developed economic systems are in a place to give more attending to making a more sustainable constructing stock by upgrading, by new developments or the usage of new advanced engineerings. All public procurance should be made consistent with authorities policies for presenting sustainable development, most notably in footings of waste minimisation, H2O efficiency, community regeneration and societal inclusion. In that sense, Private Finance Initiative ( PFI ) as an advanced procurance path can play a cardinal function within the industry due to the graduated table of investing involved ; the greater easiness of act uponing the little figure of histrions involved ; and the manner in which PFI contracts secure the long-run battle of contractors. However, sustainability considerations are non sufficiently embedded in the PFI procedure to guarantee consistent bringing, and success is extremely reliant on the motive and expertness of single public sector clients and private contractors ( Green Alliance ( 2004 ) ) . Sustainability within the building industry has no clearly settled definition and no settled organic structure of bing pattern and procedures. The industry has to understand what sustainability is in its context and concentrate on creative activity, prolonging and airing of cognition for sustainable building across the multiple interest holders involved in building undertakings ( Shelbourn et al. , 2006 ) . Many building companies in the UK follow the authorities ‘s aim for sustainable development which is economic growing and prosperity, effectual protection of the environment, careful usage of natural resources ( natural resource protection and environmental sweetening ) and societal advancement. The UK authorities has produced enterprises to title-holder sustainability within the building industry to accomplish sustainable development marks. Recent research plans such as ‘Partners in Innovation ( PiI ) ‘ ( Shelbourn et al, ( 2006 ) ) and others have been funded to back up sustainability within the building industry ( Raynsford ( 2000 ) ) . The ‘Government Construction Clients Panel ‘ ( dwelling of representatives with duty for procurance for most authorities organic structures ) besides has a mark to accomplish sustainability in each undertaking. This enables the authorities to take a prima function, and showcase good pattern in advancing sustainable building ( DEFRA, ( 2004 ) ) . It is the writers ‘ contention that, every company in the building concern must hold a sustainability policy which will be developed and communicated within the organisation. Those policies can be Sustainability Policy, Environmental Policy, Health and Safety Policy and Sustainable Procurement Policy. The policy and rules of sustainability creates a sustainable development which is supported by a sound sustainability scheme. The purpose of such schemes is to develop a common apprehension of the sustainability issues and present effectual and targeted attacks for each stakeholder to lend to accomplishing a more sustainable building industry. In order to recognize all these policies and scheme it is perfectly necessary to hold a Board and Advisory Committee within the organisation that supports and commits to sustainability as a scheme and acts as a nexus between office and operational activities at site degree. Having set these marks fiting with the Government ‘s sustainab le development, building houses must put specific one-year marks for each concern unit and each building undertaking as a whole. After that each house must besides put for his undertakings and company a sustainability appraisal standard which is linked to marks and Key Performance Indicators ( KPI ‘s ) aligned with the concern scheme of the house. These are meant to be some sporadic thoughts from the writers to the building houses that are likely to follow in execution of Sustainability Policy and Strategy in their organisations. The experiences from some taking UK building companies have shown that there are strong concern benefits for more sustainable building. As a successful instance â€Å" Early Solutions Together – Eastern time † programme of Morgan-Est ( Part of Morgan Sindall ) and â€Å" Making Tomorrow a Better Topographic point † programme of Carillion can be named as two good illustrations of sustainable thought and execution in the UK building industry ( Morgan-Est, 2009 ; Carillion, 2009 ) . Carillion is winner of its category – Best Green Company in the UK for medium to big houses Awards in 2008 and Morgan-Est is the victor of Green Apple Award for Environmental Best Practice. This is besides demonstrated through research carried out by Sustainable Construction Task Group ( BRE ( 2001 ) , which concluded that there are clear advantages to be gained, but merely if sustainability is portion of a long-run concern program. This is reinforced by the Building Research Esta blishment, where research has concluded that â€Å" aˆÂ ¦being sustainable is every bit much about efficient profit-orientated pattern and value for money as it is about assisting the environmentaˆÂ ¦ † ( BRE Report ( 2002 ) ) . Such consequences have given the building industry an improved consciousness of sustainability issues. In 1999, around 150 quality of life indexs were produced to better the wellbeing of UK citizens ( Audit Commission ( 2002 ) ) . The industry has begun to acknowledge that monitoring and coverage on sustainability is a critical portion of their concern. Cardinal Performance Indicators, Environmental Performance Indicators, and the acceptance of benchmarking have become progressively common topographic point, and many companies are now bring forthing environmental and sustainability studies, with corporate societal duty going common pattern ( Movement for Innovation, ( 2000 ) , CIRIA ( 2001, 2006 ) . Sing building in developing states, Ofori ( 2007 ) states that, an organized action should be taken to guarantee that the high volume of building that will be undertaken in the development states in the procedure of urbanisation in the ways that are socially and ecologically impact of building. He stresses that this will necessitate a wide duologue between authoritiess, building industry, academe and NGO ‘s at national and international degrees towards the development and execution programs for sustainable building. 4. Turkish building services bunch Harmonizing to Katsarakis et Al ( 2007 ) , the building services bunch in Turkey is the thirteenth largest in footings of exports and has demonstrated a compound one-year growing rate ( CAGR ) of 63 % for the period of 2002 – 2006 in international projects. While the building services bunch represents merely the 6 % of Turkey ‘s gross domestic merchandise ( GDP ) , together with all complementary and related industries, it still accounts for 30 % of GDP harmonizing to the TCA ( 2009 ) records. Construction plays a important function in Turkey ‘s economic system using about 1.4 million people which is about 5.5 % of Turkey ‘s entire employment. Turkish building sector is chiefly composed of Small and Medium Enterprises. This composing is really similar to the European building sector. The building sector is chiefly a domestic sector and merely 4 % is international building. The European building industry excessively is composed of about 97 % of SME ‘s. The bunch is divided into two groups: the lower-quality domestic-only set of houses and the higher choice international houses by Katsarakis et Al ( 2007 ) . These two groups portion some but non all bunch participants. On the domestic side, there are more than 30,000 active local houses. On the international side, there are over 140 houses registered to the Turkish Contractors Association, 23 of which are among the 225 largest building companies worldwide in footings of abroad activities ( ENR, Engineering News records ( 2008 ) ) . Harmonizing to a study on the web site of TCA about the Turkish Contracting in the International Market, â€Å" in the last 36 old ages, u p until the terminal of 2008, Turkish Contractors have undertaken about 5,000 undertakings in 70 states, with a combined value of some 130 billion USD. Turkey ranks among the top 12 manufacturers of edifice stuffs in the universe, with such merchandises as cement, glass, steel and ceramic tiles taking a prima function. † Further detailed information is provided in a publication by Yapi Endustri Merkezi ( 2007 ) as follows sing the services of the building and the related industries, Turkey is the 11th largest manufacturer of steel in the universe and third-largest in Europe. Turkey ranks 6th in Europe and 15th in the universe in the production of articles of steel. Turkey is the universe ‘s richest state in marble, with a 40 per centum portion of entire planetary militias. Turkey is the universe ‘s 5th and 4th largest manufacturer of ceramic tiles and ceramic healthful ware, severally. Turkey is among the top glass makers of the universe. Turkey is the 6th largest manufacturer of pigments in Europe. Turkey is the 3rd largest manufacturer of plastic doors and Windowss in Europe. There are 200 major technology confer withing companies in Turkey which are supplying 65 % of the proficient consultancy services realized in Turkey and 90 % of the consultancy services required by the Turkish houses abroad, harmonizing to the records of Association of Turkish Consulting Engineers and Architects ( ATCEA ) presented at their web site. Their one-year turnover is about $ 350 million, and they employ about 5,000 people. 5. Turkey ‘s place on sustainable development Business involvement in corporate sustainability is turning in Turkey. Nemli ( 2009 ) investigated taking Turkish companies ‘ attack to corporate sustainability regarding, Their attitudes and attacks toward sustainability, Their chief patterns associating to environmental and societal sustainability, The grounds why companies adopted sustainability patterns, The grounds why companies have non adopted sustainability patterns and Which companies produce environmental, societal or sustainability studies. Nemli ‘s pre-research surveies showed that merely a few of these companies had formal sustainability schemes. Therefore an scrutiny of the sustainability patterns of these few companies would be more enlightening about sustainability in Turkey. The fact that there are so few companies prosecuting sustainability schemes in Turkey indicates that Turkish companies are at the beginning of sustainability execution in their concern. Nemli ‘s research was related to the fabrication companies and none of the examined companies was involved in the building sector. Harmonizing to Turkey ‘s National Report on Sustainable Development by Ministry of Environment ( 2002 ) and besides summarized in a survey made by Ozkan ( 2003 ) , most of the environmental statute law in Turkey has been affected during the past decennary. An overall appraisal of the Turkish environmental statute law indicates that during the past two old ages, the construct of sustainability was clearly included in the Torahs and ordinances put into consequence. The undermentioned ordinances are considered to be vitally of import, Environmental Impact Assessment Regulations, Solid Waste Control Regulations, Hazardous Waste Control Regulations, Air Quality Control Regulations, Water Pollution Control Regulations, Waste Control Regulations, Hazardous Waste Control Regulations. Furthermore, the Ministry of Environment is taking farther legal steps to forestall and command environmental pollution. In this respect, the bing statute law is being reviewed as portion of the attempts to harmonise them with EU statute law. It is anticipated that this measure will lend well towards accomplishing the ends for sustainable development. Turkey had been prosecuting policies in the countries of energy efficiency and environmentally sound engineerings, every bit good as industrial pollution control.A To accomplish sustainable energy development and energy efficiency, the Government had been beef uping attempts to develop and utilize safe engineerings, advancing research and development for appropriate methodological analysiss, raising public consciousness of the issues, and measuring environmental impacts ( A °lkin ( 2006 ) ) .A Harmonizing to the National Report on Sustainable Development 2002, during the past few old ages at that place has been an addition in industrial preparation plans related to work safety, environmental direction systems, quality confidence, and in-service preparation. These plans have been initiated by the Union of Chambers of Commerce and Industry, stock exchanges, Small and Medium Industry Development Organization ( KOSGEB ) , the Quality Association ( KALDER ) , universities, and research establishments ( Ozkan, ( 2003 ) ) . Recycling of edifice stuffs is a really new construct in Turkey. It is merely after the lay waste toing temblor of 1999 in the Marmara part, that some attending has been paid to the huge sum of constructing dust accumulated from the collapsed and dismantled edifices. Waste recycling is recommended and encouraged by the Turkish Ministry of Environment ( Ozkan, ( 2003 ) ) . The Regulations for solid waste disposal go so far as to order that recycled stuffs should be preferred to new 1s. However, the waste referred to in the ordinances belongs to industrial procedures or boxing merely. Harmonizing to the National Report on Sustainability, â€Å" Waste direction is one of the major constituents of the execution of the sustainability rules. Industrial waste direction requires that wastes caused by industry, production and services be managed for the protection of environmental and human wellness by cut downing the loss of natural stuffs used in fabrication. Reducing the sum of waste at the beginning, waste recovery and recycling, every bit good as implementing appropriate waste disposal techniques are among the basic constituents of sustainable development. † ( Ministry of Environment, 2002 ) Harmonizing to Turkey ‘s National Report on Sustainable Development ( 2002 ) , the type of industrial waste in Turkey as a underdeveloped state, is non much different from the type of waste encountered in the developed states of the universe. In order to quantify the sum and composing of industrial waste and to look into the attendant environmental jobs caused Turkish Statistical Institute ( TUIK ) and assorted local authoritiess and industrial organisations ( Union of Chambers of Commerce, Industry, Maritime Trade and Commodity Exchanges of Turkey, Chambers of Industry of Istanbul and Kocaeli ) have conducted independent surveies to develop industrial waste stock lists for the period of 1991-1995. Although the industrial waste stock lists of the fabrication sector for 1994-1997, prepared by the TUIK, did non cover the full state, it is the lone legitimate waste stock list informations bank that exists in Turkey. Besides the Industrial Waste Statistics of TUIK, the Ministry of Environment has besides concluded a elaborate industrial waste stock list undertaking in 2002, which encompasses the Marmara, the Mediterranean, and the Western Anatolia Regions ( Ozkan, 2003 ) . Waste generated by the building industry has non been accounted for in the statistics for industrial or family wastes. Since information for waste produced or disposed by the building industry has non been collected by any of these bureaus, the impact of waste from building industries is besides non known. Esin and Cosgun ( 2007 ) argue that retrieving of building waste is non yet prevailing in Turkey. The primary environmental concern should be the prevention/reduction of the coevals of building waste. Sing the sum of waste generated, Turkey declared in the 9th Five Year Development Plan that the primary mark for commanding solid waste is the decrease of the sum of waste generated ( State Planning Organization ( SPO ) , ( 2006 ) ) . One of the basic rules of the said Development Plan is â€Å" Natural resources, cultural assets and the environment will be protected sing the hereafter coevalss, every bit good † . The study furthermore underscores the Turkish State ‘s decision and will sing the sustainability in resource use in following diction: â€Å" Rapid population growing and industrialisation continue to be of import factors endangering sustainable usage of natural resources. The uncertainnesss about the responsibility and authorization distribution among establishments, for the sustainable usage of natural resources while protecting the environment without adversely impacting the production procedure, could non be adequately eliminated ( Item 159, p.38 ) † and â€Å" More efficient production and less waste will be achieved by increasing the effectivity in natural stuff usage with the execution of environment friendly techniques in industry ( Item 463, p.87 ) † . 6. Discussion Turkey has a strong building sector which can easy be considered as a regional leader in quality building and building stuffs. From the literature study it is evident that Turkey ‘s building industry ‘s sustainability place is non to the full structured yet. A few writers indicate that Turkish companies are at the beginning of implementing policies for sustainability. A study done by Turk ( 2009 ) studies that out 68 companies which are members of TCA surveyed had revealed that merely 28 of them had ISO-14001 enfranchisement. The prevailing governmental sustainability papers in Turkey is dated to 2002. Sustainability is a path that all building industries must travel through. This necessitates the industry to alter their concern scheme and organisational constructions and civilizations. This is a long-run and uninterrupted procedure that needs alteration and version of the sustainability attack to make competitory advantage over other challengers in the industry. Global challenges associated with sustainable development are multifaceted, affecting economic, societal, and environmental concerns. These challenges have deductions for virtually every facet of a building house ‘s scheme and concern theoretical account. Most directors frame sustainable development non as a multidimensional chance, but instead as a unidimensional job, affecting ordinances, added cost, and liability. The jobs of stuff ingestion, waste, and pollution associated with industrialisation nowadays an chance for houses to lower cost through the development of accomplishments and capablenesss in pollution bar and eco-efficiency. Investings made to protect the environment or as portion of societal duty were seen as investings that increase the overall costs and diminish fiscal return. Clean engineerings are normally more efficient therefore cut downing emanations and increasing productiveness. Reducing natural stuff usage and increasing recycling and recovery can cut down production costs. There are chances for cost nest eggs that may non go evident even though the benefits accrue straight to the company, until the company is motivated either by ordinance or concerns to better sustainability public presentation to analyze ways of turn toing these jobs and to put in the necessary research ( Nemli, ( 2009 ) ) . The companies ‘ committedness to corporate societal duty and overall repute may be an of import motivation factor for its current and prospective employees. There is besides an insurance value associated with repute. In the event of a job, a company with a good repute can bring on more supportive responses from stakeholders. Output extends beyond organisational boundaries to include the full merchandise life cycle-from natural stuff entree, through production procedures, to merchandise usage and disposal of spent merchandises. Output therefore involves incorporating the desire of the stakeholder into concern procedures through extended interaction with external parties such as providers, clients, regulators, communities, non-governmental organisations, and the media. As such, it offers a manner to both lower environmental impacts across the value concatenation and enhance legitimacy and repute by affecting stakeholders in the behavior of ongoing operations. ( Hart et Al ( 2003 ) ) . The industry and the disposal have to develop a macro policy which will incorporate societal, economical and environmental policies needed to accomplish a sustainable development of the Turkish building industry as a whole. A holistic sustainability policy covering the full building bunch does non be in Turkey yet. The industry needs to make a political organizational organic structure which is compatible with the demands of sustainable development and which is compatible with similar organisations across the universe. For case, The UK Government ‘s scheme for more sustainable building ( DETR, 2000 ) suggests cardinal factors for action by the building industry by widening the basic subjects. These include design for minimal waste ; thin building ; minimise energy in building and usage ; make non foul ; preserve and enhance biodiversity ; conserve H2O resources ; respect people and local environment ; and put marks, proctor and study, in order to benchmark public presentation ( Raynsford ( 2000 ) , Langston & A ; Ding ( 2001 ) , Miyatake ( 1996 ) ) . These could every bit use to Turkey. Advanced experiments from good illustrations in other states can be adapted to the constitutions of the Turkish building sustainable development attempt. The sector requires more funding to build sustainable undertakings due to the current higher monetary value of stuffs, substructure costs and the land-use ratio. It is expected, nevertheless, that the high cost of sustainable building will worsen in line with a rise in the figure of such undertakings. Many clients and end-users are going witting of the sensitive state of affairs of the environment, and are demoing an increasing penchant for buying sustainable terminal merchandises. For illustration, sustainable lodging reduces operational costs and H2O use, and offers improved security. Meanwhile, lodging investors, though willing to establish nature-sensitive undertakings, are hesitating about the hereafter of the sustainable lodging sector given the high costs associated with it. Sustainable development is one of the most outstanding issues which are emphasized in the Turkey. National Environment Strategy and Action Plan prepared in order to accommodate to the societal and economic state of affairss in Turkey. In the Turkish National Report ( 2002 ) , it is emphasized that in order to sum up the current state of affairs, it has benefited from the Environment subdivision of the 9th Five Year Development Plan ( 2007-2013 ) increased sensitiveness to the demand for a clean environment. Although the environment is a moderately of import issue in Turkey, it has some advantages and disadvantages in respects to environment and sustainable development. The advantages are as stated by TUBITAK ( 2003 ) , Our natural resources ‘ non being wholly polluted, The increasing consciousness of the environment particularly among the immature population, The adequateness of scientific and proficient human resources who can work in this field make it favoured in respects of accomplishing sustainable development. The disadvantages of Turkey in this field are, In malice of non being wholly polluted, their is go oning pollution of natural resources, Making usage of natural resources related to an investing for environmental betterment without taking attention of the set purposes, Not maintaining a record of information and informations consistently related to environment, Data which are recorded holding no criterion in footings of informations aggregation, confirmation, rating and transforming into information. In relation to development programs and sustainable development in Turkish metropoliss, Ercoskun ( 2005 ) argues that the current development programs of metropoliss do non see urban individuality and ecological values and the regional programs do non see infinites between edifices, clime, illuming, way, air circulation, natural energy, etc. , ensuing the Turkish metropoliss to be unsustainable. Furthermore, she states that planning is one of the chief tools in Turkish sustainable development and concluding that the Turkish planning system ( Development Plans, Laws and Applications ) has to be challenged from the sustainability point of position. Supplying sustainable development is non merely limited to direction of natural resources, providing equipment or commanding them. Persons should carry through their responsibilities as responsible citizens in order to accomplish sustainable development with respects of environmental protection. Therefore, it is imperative that persons be taught the topic of sustainable development get downing in primary school, every bit good as doing them cognizant of the environment.

Henrik Ibsen’s A Doll’s House Essay

The role, treatment, disadvantages, and sacrifices of women in their societies are vital themes in both Federico L’Orca’s The House Of Bernarda Alba and Henrik Ibsen’s A Doll’s House. In Federico L’Orca’s The House Of Bernarda Alba, to start with, all characters that appear on stage are females, and men are merely talked about. In Ibsen’s A Doll’s House the protagonist is Nora, a woman who gets treated by her husband as though she were a little girl. At the time when Federico L’Orca and Henrik Ibsen wrote their plays, it was normal for women to get treated as anything but equal to men. Women were expected by men and by their society to do nothing more than stay at home, cook for their family, get children, and then take care of their children as well. Although Ibsen and L’Orca wrote these plays several decades apart, since Ibsen wrote his play at the turn of the century in Norway and L’Orca wrote his in 1930’s Spain, the expectations of women were pretty much the same. It was not normal for women to receive an education, let alone a good one, and women were not allowed to vote. In A Doll’s House there are three female characters: Nora, Mrs. Linde, and the maid working for Nora. All of these women have to sacrifice something and have disadvantages, simply because they are women. Every character in The House Of Bernarda Alba has to suffer because they are women. Spanish tradition in the 1930’s forces them all to isolate themselves from the outer world for eight years of their lives. In The House Of Bernarda Alba, Bernarda Alba and all of her daughters have to mourn the death of their father. This is Spanish tradition, and so they all have to live in their house for eight years, completely isolated from the rest of society. They may only wear black, even in the scorching heat of southern Spain. This already shows how harshly women were treated. Bernarda Alba and her daughters are forced to isolate themselves from the outside world completely, whether they want to or not, because of tradition. The eight women are forced to give up eight years of their lives in which they may do nothing but mourn. Also, the fact that a woman has to kill her own child when she gets pregnant, and is then hunted down by the whole town and killed herself, shows how women were viewed and treated. Also, a woman could often not decide who she wanted to marry, and when a women got married it was often just nothing more than a business deal, and the feelings of the woman were completely ignored.

Sociology written assignment - Essay Example People often said that Josie had a bad reputation. Personally, I found Josie to be a nice person. I was in many of her classes and would often have conversations. I thought she was an interesting and curious person. She never made fun of me and always seemed to generally be respectful. However, other people felt that she had a bad reputation. They didn't know her well, but that was their superficial impression. They heard rumours about her which often were not true. Her reputation, which spread quickly in the school, seemed to precede her wherever she want. She became a character that people would talk about even though they didn't actually know her in person. People who had never had a conversation felt that they knew everything about her. They felt they were in a position to judge her because there was a kind of story being told by everyone about her. In a sense her reputation made her a public commodity. It is clear from the research that bad reputations are created when people de viate from social norms. In Josie's case it was clear that a lot of her behaviour set her apart from the other students in the school. She experimented with alcohol before other students and had friends who were a fair amount older. She also took part in a number of disturbance, further marking her out from the social group.

While Marquis argues that abortion is immoral as killing deprives the fetus of its future and Steinbock believes that abortion is not wrong based on the moral status of the unborn and its lack of consciousness, their arguments continue to confound rather than illuminate the morality or immorality of the issue. Marquis contends that abortion is seriously immoral as taking another person’s life, as for instance, an adult’s, as it dispossesses him of his future. This is akin to the killing of a fetus. Marquis asserts that fetuses are in the same category as adults with regards moral value. Thus, the immorality of abortion rests on strong presumptions such as on the dogma that killing is wrong. The concept that killing is brutal and thus, it is wrong does not explain the depravity of the act. For Marquis, what makes killing unacceptable is its consequences on the victim as the loss of one’s life is considered the greatest loss. This loss constitutes loss of activities and gratifications which make up the valuable future of the victim. As death divests a human being of the ‘value of his future,’ the most justifiable reason against killing an adult individual is the consideration of the ‘loss of his future.’ In addition, Marquis argues that other l iving entities and species have similar ‘future’ like our and believes that it is likewise wrong to kill animals. Although he does not support active euthanasia, he admits that killing the ‘very ill or the dying’ cause no wrong. The heart of Marquis’ arguments, however, lies on his contention that killing an infant or fetuses amounts to immorality as they have acquired ‘futures of value.’ As the personhood theory does not put to light the immorality of killing, this notion should be replaced by the idea that

Clouds Seeding Essay Example | Topics and Well Written Essays - 1000 words

Clouds Seeding - Essay Example This paper takes a closer look at the concept of cloud seeding, the types, uses, and impact on the environment (Keyes 3). The main objective of cloud seeding is to cause enhance the precipitation through rain and snow and reduce the formation of hail and fog. This technology initially launched to research on and to monitor the climatic conditions of various regions in the world has been widely adopted by world’s leading economies with the main objective of negating the effects of extreme weather conditions. Under normal circumstances, harsh weather conditions are mostly experienced in the temperate countries especially during the winter and summer (Keyes 3). Although several methods of cloud seeding exist, the most common categories are the aerial cloud seeding and ground-based cloud seeding. Aerial cloud seeding involves the use of light aircrafts in the modification of weather at a considerable height from the ground. Ground-based cloud seeding on the other hand, entails the launching of intended substances into the earth’s atmosphere to carry out the same purpose. Irrespective of the procedure used to conduct cloud seeding, the underpinning idea is the same as it is the same process conducted in different procedures. Since the essence of cloud seeding is to promote the precipitation of condensed cloud, the methodology involves the injection of certain substances or chemicals into the clouds with the most commonly used being dry ice and silver iodide (Keyes 3). In some cases, the use of propane has proved successful although scholars from certain quarters questioned its efficiency. Since for successful could seeding to take pla ce there has to be super cooled water, the use of silver iodide has solved the problem through its ability to stimulate freezing nucleation because it is crystalline in nature. Research shows that dry ice and propane perform better than silver iodide as far

Innovation and Change (CRITICALLY EVALUATE THE CLAIM THAT ANY Essay

Innovation and Change (CRITICALLY EVALUATE THE CLAIM THAT ANY ORGANISATION CAN LEARN TO BE INNOVATIVE) - Essay Example Innovation fuels improvement: improved products and features, improved methods, and improved knowledge†. In this regard, the essay aims to address the following crucial issues: (1) to define ‘innovation’ and to explore the extent to which it can be promoted and embedded in an organisation; (2) to determine diverse approaches, strategies, techniques and issues around this issue; (3) to respond and address the question: can any organisation draw on them and learn to be innovative? (4) To find out which approaches, strategies and techniques deemed particularly interesting or significant or important vis-a-vis the question and the rationale for one’s choice. ... 39). Tucker’s suggestions also tie in with the incremental innovation strategy, suggesting ‘Building on current resources can increase product innovation’. Therefore it could be argued that any organisation can learn to be innovative with the appropriate resources. The experience of Mark Zuckerberg founder of Facebook is a prime example of an individual’s pursuit to introduce an innovative method of networking. His foundation was instrumental in launching Facebook, a social networking site that revolutionized online interconnections and interface (Carlson, 2010).The application of his innovative design could be synonymous to the concept of fordism, where mass consumption as combined with mass production, produce sustained economic growth and widespread material advancement. Despite the controversies and challenges that Zuckerberg encountered, he remained steadfast and determined to take accountability to adhere to the ideals and philosophies he believed in. Carlson (2010) has revealed that â€Å"the site has become one of the biggest web sites in the world, visited by 400 million people a month† (p. 1). This would also suggest that entrepreneurial talent is required in order to make an innovation successful. Likewise, learning about innovation theories is a matter of decision and commitment. The theories on the 4Ps of innovation (product, process, position and paradigm) (see diagram 1) could easily be learned from academic sources (Kostic, 2003, par. 3). But the experience of Facebook exemplifies innovation as a paradigm due to the major shift in thinking demonstrated by Zuckerberg that has beenradical in revolutionizing social networking

Careers Education System in Cyprus Thesis Proposal

Careers Education System in Cyprus - Thesis Proposal Example Career counselling in Cyprus serves to orient and enlighten the pupils with future employment opportunities and enable them to fully realize their aptitudes and aspirations so they can pursue the most suitable specialization. Having this in mind, the question now is what career guidance program will be suited for fulfilling the needs of the student population. As Cyprus already has a national career guidance program applied in its school system, the issue that seeks to be addressed is the changes that needs to be implemented for it not only to be effective but also responsive to the needs of the students, parent, school management and school staff. This research shall focus on the needed changes in the guidance system of Cyprus as determined by the contemporary social setting so as to be responsive to the needs of the students, educator and parents. To achieve this, the current system of the Cyprus guidance and career provision shall be discussed and analysed for inadequacies pointed out by relevant studies and research. Weak points shall be identified and solutions shall be formulated, again analysed against the backdrop of relevant research. It shall be born in mind of the very important principle pointed out by the National Centre for Guidance and Education (2004, foreword) which is the fact that guidance planning shall rely not only on the expertise of the guidance counsellor but also on the school management, staff, parents and students. In additional, there is a need to go beyond the school premises as the only setting for career guidance programs formulation as there is other equally important externalities that affect such provision directly or indirectly such as government policy and industry trends. The purpose, in summary, is to provide a holistic analysis of different factors affecting Cypriot Career Guidance services and be able to formulate strategies to address any incongruence and insufficiency so as to be responsive to the needs of the students, educators and parents. Review of Related Literature According to the NCGE (2004), career guidance refers to a range of learning experiences provided in a developmental sequence that assist students to make personal and social, educational and career choices about their lives and to make transitions consequent on these choices. A school guidance plan is seen to have these benefits: it provides direction by stating the objectives and priorities of the provision of guidance in a school; it enhances the provision of guidance by targeting the needs of students; it focuses the school's resources to where they are needed most; and lastly, it allows staff to contribute to developments and changes in a positive and collaborative way. Based on these facts, the school guidance system is said to be an integral part of the school plan. (NCGE, 2004) Guidance provision in schools involves a range of guidance and counselling activities and services (Department of Education and Science's Guidelines for Second Level Schools, 1998), relating to students' access to appropriate guidance for an overview on the importance of guidance. Guidance activities that assist students to make choices include: (a) counselling which deals with helping students to explore their thoughts and feelings, and the choices open to them; giving care and support to students learning to cope

Unit 3 Organisational Behaviour, Unit 5 Aspects of Contract and Assignment

Unit 3 Organisational Behaviour, Unit 5 Aspects of Contract and Negligence for Business, Unit 31 E-Business Operation - Assignment Example Valid contracts act as tools for a business enterprise that can be used as defence mechanism to protect its resources. Contract is essentially a promise between two or more parties, and the promise is legally bound with the implication that court of law will intervene in case there is any breach of the promise (Ryan, 2005, p.3). There are various essential elements for the formation of a valid contract. First of all, there must be an offer made by one or more parties and acceptance of the offer by other parties. An offer is a legally bound promise which means all the terms and conditions attached to the offer have been accepted by both parties. Acceptance occurs when the party responding to the offer expresses agreement to the offer, and the acceptance must be explicit and unequivocal as law will not consider an offer as accepted merely because it has not been expressly refused. There must also be a clear intention of both parties to enter into a legal relationship. The parties to th e contract should also be capable to enter into a legal relationship like the involved persons should be adults, mentally fit, and mentally alert so that they are aware of the terms and conditions of the contract. A person is considered an adult when he or she is of legal age requirement. In most countries the legal age requirement is 18 years. A person is not considered mentally fit if he has been declared mentally incompetent by the court. Finally, a contract signed by an intoxicated person is not considered as valid contract since such a person is not mentally alert to become aware of the terms and conditions of the contract. There should also be free consent from both parties, i.e. neither party should force the other party to enter into a contract. When a valid document is signed it becomes a legally bound contract and is assumed that all the terms and conditions have been understood by both the involved parties. A contract is made up of various terms

The Problems Faced By Archaeologists in Reconstructing Anglo Saxon Society between the 5th And 7th Centuries from Anglo Saxon Cemetery Evidence Essay Example for Free

The Problems Faced By Archaeologists in Reconstructing Anglo Saxon Society between the 5th And 7th Centuries from Anglo Saxon Cemetery Evidence Essay Conquest of England by the Anglo Saxon began in middle of the 5th century. During this time Celts inhabited England and had been ruled by the Romans for more than 360 years. Due to the short lived rule by the roman, the roman civilization started to fade away hence left the most of the towns abandoned. This included most of the villas in the countryside and the Celts went back to live in hill forts and other protected wooden stockades. There was deliberate attempt by Arnold to explain the changes that dated from roman Britain to early Anglo-Saxon England based on an elite migration which is considered as a type of a late reception of processual archaeology as illustrated by Scull. There are a large number of ornaments found in a number of graves and what is so clear about them is that the origin of these ornament is definite in a given district or sate. Also these ornaments are clearly a descendant of the people of which these burial sites are from. Hence it can be conclusively be said that these people did obtain their ornaments right away from their own locality and not outside the district they live in. a problem will arise in deciding on the validity of the archaeological interpretation of the Anglo-Saxon conquest of Britain. Here, the owner of these ornaments is unclear as whether they are the Saxons, Angles or Romano-Britons who are the owners of these ornaments. Lethbrigde’s interpretation would help pin point the real owners of the artifacts and the material remain1. These were done with other archaeologists who in many ways faced a number of challenges. Some of these challenges included the following:               Ã‚  Reconstruction of clothing; there were variations noted on the dress fasteners in the women’s clothes. The clothes had one, two or three brooches that were worn in various positions on the chest and others on the shoulder. Dress-fastening for the men was limited to sleeve fasteners and buckles. Reconstructing clothing from this evidence meant that the range of dress fastening was dictated by a number of factors. These factors include social identity and the mode of display. It was further argued that the dress fasteners placed in graves may have been chosen on other reasons rather than the functional relationship to the garment being worn or the direct relationship of the grave clothing and the daily wear. The textiles of which we have knowledge about had been made into clothing. Though there is a possibility to reconstruct some of the clothing through the remains in graves by using the position of dress fasteners like buckles ( cook 1974; Bell 1981 ; Owen Crocker 1986) Damage of skeletons during excavation. The excavation of skeletons was exceedingly hard as a result of the conditions of the subsoil and dry weather. The skeletons were also not well preserved because of the circum-neutral pH of the local subsoil and the ploughing which later brought about disturbance. The subsoil surface was also experiencing compaction by the box scrappers. The hard and dry subsoil conditions meant that it was difficult to excavate and remove the skeletal remains without sustaining some damage. The removal of skeletons followed a certain process. The box scrapper could first reveal the site in an inadvertently manner and later the whole site cleaned with hoes. This was to be followed by base planning at 1:50 and then excavation by hand. The excavation was done by use of trowels, small chisels and brushes. The fully excavated skeletons in grave pits were then photographed in black and white and drawn at 1:10. The whole process seemed cumbersome and at the end no acc urate results could be sought. At times the burials sites were discovered accidentally hence damage of these artifacts and bones are more likely to happen with the use of metal detecting activities. The requirement of these archaeological studies is that the whole burial grounds should be intact to maximize data recovery process. Methods for protecting and close examination of statigraphy should have been in place. This would minimize the problem of retrieval and analysis of organic materials such as textiles. With the increasing human activities such as formal settlement and cultivation such burial sites are more prone to destruction and hence limited information base. Identification of (vertical status related) and horizontal (gender, age) social groupings. Understanding the physical conditions of the people in the Anglo Saxon was a big problem. Provision of reports on the age, physical height and the biological gender of the dead person and the time of death have only been achieved through the scientific analysis and improved technology. It was also impossible to have information on any signs of genetic traits and deformity or trauma present in the skeleton record. Transformation of these kinds of data into cultural interpretation remains a problem that need to be addressed. Evidence interpretation; Coming into an agreement upon realization of a notable phenomenon was another problem. Taking the case of the suspended floor model where various persons argued out on the purposes on various sections buildings, we see how each person tried to argue out. This argument hindered the ease of putting an all one agreed story on the Anglo Saxon. It leads to inclusion of argument from more than one person hence limiting the accuracy desired. There was an argument on the kind of floors that the vernacular buildings had and also an attempt to relate them to the 12th and 13th century buildings. The earliest surviving buildings which date to the late 12th and early 13th centuries do not have planked ground floors (Walker 2009) and so it will be remarkable if majority of the buildings in the 6th century England possessed them. Difficulty arose in an attempt to explain the validity of the pit as to whether it served as an air-space or not. Decisive evidence mainly on the subject matter about superstructure of Grubenhauser will tend to depend on factors of plausibility. Suspended floors could end up being elusive evidence. Grouped Grubenhauser archaeological features will tend to compromise more than one form of superstructure (West 1986; 116-21). This will in the end require re-evaluation that consists of a detailed study of the Grubenhaus fills to ascertain the artifacts in relation to the date and function of the structures. Re-evaluation is time consuming and costly, hence the study team will be forced to redo their study once more based on a given number of micro morphological studies to come up with exaction records. One notable example of misinterpretation of evidence id that of tertiary deposition of Grubenhaus fills that had little relationship with the use of the building. It brought out this contradictory evidence to the lime light and hence dispelling the notion of assuming little matter of great importance (Tipper, 2004:107) Location of the ancient cemeteries challenged the reconstruction of the Anglo Saxon society. Distinct boundaries where miscreants were disposed based on the customs which were never recorded and documented made it hard to identify areas to focus. The problem of Charters references to access places which exhibit patterns of local practice and dialect was also of big concern. There is a prevalent view that the local estates and the hundreds within which they were grouped are products of the late Anglo Saxon period1. This could be challenges by a series of execution sites with origins scientifically dated to the 7th century. Hence the territorial limits denied the archaeologists a chance of finding the near to exact places of carrying out their work. It proved a hard task to locate cemeteries as it required appreciation of the above ground appearance. This area as usual was characterized by mounds and mortuary houses the only problem arose on how these areas of dignity were maintained o ver time. Putting into record such phenomenon was a hard task for the study team for there existed little management evidence such as paths, internal divisions or vegetation or even buildings associated with burial sites. Other notable challenge was to contrast the difference between shrines as a form of cemetery structures and other mortuary houses (Hirst1985:24). Instances of cremation rendered the archeological study to be narrow; Some instances of the burials have indicated that there was close contact with the Roman culture. This can be exemplified by the right of inhumation which was practiced by the native Romanized population. Cremation was a common practice especially outside the empire5. As recorded y the different times of the AD200-400 in northern and central Europe. There was inconsistency in the differences presented by the Germanic graves. This further led to the much unnoticeable variance of the whole archeological results. Although in some areas burials of different orientations have been brought out in instance where there existed a large cemetery for example at Krefeld-Gellep, in Westphalia. In such instances careful examination of the artifacts and bones was needed in order to ascertain and draw analogies from the historical and ethnographic sources. (McKinley 1994:72-81; Williams 2004b). Cremation involved a sequence of materials practices and places, Williams 2001.this practice did reconfigu re the deed’s identity in many ways including burning the cadaver and treatment of ashes. As seen the most valuable evidence in the cinerary urns included the burnt bones, contrary to the statement the bones sometimes were absent suggesting a possibility that the practice took place without necessarily the body being present (Mckinely2003:11-12). There are notable fragmented remains in most of the urns and the end result is that they offer invaluable information to the study team. Although the positive thing about the remains includes giving information on such variable such as number of individuals present, age and sex. From the estimated weight and degree of fragmentation and also the colour of the bone pyre technology and post cremation aspects can be reconstructed easily (McKinley 1994:82-6). There has been revelation of a wide range of practices such as sacrificed animals placed on pyres. Wild animals such as fox and deer were the ones mostly used to offer sacrifice. Conclusion               Ã‚  As much as Anglo-Saxon religion is difficult to perceive, religion is an important aspect in our daily lives. This implies that religion can’t be ignored as it forms part of our fundamental shaping of our behaviors. There is need to have some level of local institutions that are charged with the sole responsibility of maintaining and running cultic sites such as cemeteries. The enhancement of the understanding of Anglo-Saxon religion will depend on the level of the various responses both social and political changes that aim to safeguard the past, present and the future history that is within the society. Closer exploration of the religious ecological context will tend to shed light on the understanding of the Pre-Christian paganisms. References Carver, (2005). Sutton Hoo.

History and Evolution of Dogs Essay Example for Free

History and Evolution of Dogs Essay Domestic dogs inherited complex behaviors from their wolf ancestors, being pack hunters with complex body language. These sophisticated forms of social cognition and communication may account for their trainability, playfulness, and ability to fit into human households and social situations, and these attributes have given dogs a relationship with humans that has enabled them to become one of the most successful species on the planet today. Although experts largely disagree over the details of dog domestication, it is agreed that human interaction played a significant role in shaping the subspecies. Shortly after domestication, dogs became ubiquitous in human populations, and spread throughout the world. Emigrants from Siberia likely crossed the Bering Strait with dogs in their company, and some experts suggest the use of sled dogs may have been critical to the success of the waves that entered North America roughly 12,000 years ago, although the earliest archaeological evidence of dog-like canids in North America dates from about 9,000 years ago. Dogs were an important part of life for the Athabascan population in North America, and were their only domesticated animal. The divergence date of roughly 15,000 years ago is based in part on archaeological evidence that demonstrates the domestication of dogs occurred more than 15,000 years ago,and some genetic evidence indicates the domestication of dogs from their wolf ancestors began in the late Upper Paleolithic close to the Pleistocene/Holocene boundary, between 17,000 and 14,000 years ago. But there is a wide range of other, contradictory findings that make this issue controversial. Archaeological evidence suggests the latest dogs could have diverged from wolves was roughly 15,000 years ago, although it is possible they diverged much earlier. In 2008, a team of international scientists released findings from an excavation at Goyet Cave in Belgium declaring a large, toothy canine existed 31,700 years ago and ate a diet of horse, musk ox and reindeer. Prior to this Belgian discovery, the earliest dog fossils were two large skulls from Russia and a mandible from Germany dated from roughly 14,000 years ago. Remains of smaller dogs from Natufian cave deposits in the Middle East, including the earliest burial of a human being with a domestic dog, have been dated to around 10,000 to 12,000 years ago. There is a great deal of archaeological evidence for dogs throughout Europe and Asia around this period and through the next two thousand years, with fossils uncovered in Germany, the French Alps, and Iraq, and cave paintings in Turkey The oldest remains of a domesticated dog in the Americas were found in Texas and have been dated to about 9,400 years ago.
