Nicaragua Geography, History, Climate Facts
Nicaragua Geography, History, Climate Facts Population: 5,891,199 (July 2010 estimate)Capital: ManaguaBordering Countries: Costa Rica and HondurasLand Area: 50,336 square miles (130,370 sq km)Coastline: 565 miles (910 km)Highest Point: Mogoton at 7,998 feet (2,438 m) Nicaragua is a country located in Central America to the south of Honduras and to the north of Costa Rica. It is the largest country by area in Central America and its capital and largest city is Managua. One-quarter of the countrys population lives in the city. Like many other countries in Central America, Nicaragua is known for its high levels of biodiversity and unique ecosystems. History of Nicaragua Nicaraguas name comes from its native peoples that lived there in the late 1400s and early 1500s. Their chief was named Nicarao. Europeans did not arrive in Nicaragua until 1524 when Hernandez de Cordoba founded Spanish settlements there. In 1821, Nicaragua gained its independence from Spain. Following its independence, Nicaragua underwent frequent civil wars as rival political groups struggled for power. In 1909, the United States intervened in the country after hostilities grew between Conservatives and Liberals due to plans to build a trans-isthmian canal. From 1912 to 1933, the U.S. had troops in the country to prevent hostile actions towards Americans working on the canal there. In 1933, U.S. troops left Nicaragua and Nation Guard Commander Anastasio Somoza Garcia became president in 1936. He attempted to keep strong ties with the U.S. and his two sons succeeded him in office. In 1979, there was an uprising by the Sandinista National Liberation Front (FSLN) and the Somoza familys time in office ended. Shortly thereafter, the FSLN formed a dictatorship under leader Daniel Ortega. The actions of Ortega and his dictatorship ended friendly relations with the U.S. and in 1981, the U.S. suspended all foreign aid to Nicaragua. In 1985, an embargo was also placed on trade between the two countries. In 1990 due to pressure from within and outside of Nicaragua, Ortegas regime agreed to hold elections in February of that year. Violeta Barrios de Chamorro won the election. During Chamorros time in office, Nicaragua moved toward creating a more democratic government, stabilizing the economy and improving human rights issues that had occurred during Ortegas time in office. In 1996, there was another election and the former mayor of Managua, Arnoldo Aleman won the presidency. Alemans presidency, however, had severe issues with corruption and in 2001, Nicaragua again held presidential elections. This time, Enrique Bolanos won the presidency and his campaign pledged to improve the economy, build jobs and end government corruption. Despite these goals,à however, subsequent Nicaraguan elections have been marred with corruption and in 2006 Daniel Ortega ââ¬â¹Saavdra, an FSLN candidate, was elected. Government of Nicaragua Today Nicaraguas government is considered a republic. It has an executive branch made up of a chief of state and a head of government, both of which are filled by the president and a legislative branch comprised of a unicameral National Assembly. Nicaraguas judicial branch consists of a Supreme Court. Nicaragua is divided into 15 departments and two autonomous regions for local administration. Economics and Land Use in Nicaragua Nicaragua is considered the poorest country in Central America and as such, it has very high unemployment and poverty. Its economy is based mainly on agriculture and industry, with its top industrial products being food processing, chemicals, machinery and metal products, textiles, clothing, petroleum refining and distribution, beverages, footwear,à and wood. Nicaraguas main crops are coffee, bananas, sugarcane, cotton, rice, corn, tobacco, sesame, soya, and beans. Beef, veal, pork, poultry, dairy products, shrimp,à and lobster are also large industries in Nicaragua.ââ¬â¹ Geography, Climate,à and Biodiversity of Nicaragua Nicaragua is a large country located in Central America between the Pacific Ocean and the Caribbean Sea. Its terrain is mostly coastal plains that eventually rise up to interior mountains. On the Pacific side of the country, there is a narrow coastal plain that is dotted with volcanoes. The climate of Nicaragua is considered tropical in its lowlands with cool temperatures at its higher elevations. Nicaraguas capital, Managua, has warm temperatures year-round that hover around 88ÃÅ¡F (31ÃÅ¡C). Nicaragua is known for its biodiversity because rainforest covers 7,722 square miles (20,000 sq km) of the countrys Caribbean lowlands. As such, Nicaragua is home to large cats like the jaguar and cougar, as well as primates, insects and a plethora of different plants.

Education - Essay Example nderstand the role of language in the learning process as supported by McConachie and Petrosky (2010) who claim that ââ¬Å"content knowledge cannot be separated from the language to represent itâ⬠(p.4). Van Lier and Walqui (2012) also stress the importance of content language by asserting that student comprehension of numerical, graphical and algebraic illustrations is in many cases a product of verbally working out the problems the help of a teacher or peer then articulate such understanding through language. However, even as studentââ¬â¢s grasp of the technical language is important, this must be enabled through a well-prepared lesson plan. Therefore, giving student teachers adequate time and flexibility to assess student needs is essential as it allows a teacher to undertake adequate background check on studentsââ¬â¢ prior academic learning. A teacher trainee can also undertake a reconciliation of state standards and the various developmental, personal and cultural dispositions of the students in order to create teaching resources and approaches that reflect to specific needs of the students (Feiman-Nemser, 2003). Although the requirements of the New York education department through the curriculum provides important guidelines for a teacher to identify essential teaching and learning experiences for the learners, there are some differences at the level of school and individual students that must be considered when planning for a lesson. Therefore, the requirements for a lesson p lan provide teachers with the power to determine complexities that might require changes for them to be implemented successfully. Videotaping of the teaching process helps in creating evidence that the teaching process actually took place. However, this has no real value to educators especially since it provides room for teacher trainees to edit the content until they feel they have a perfect copy. Therefore, the videotape can be considered as being unnecessary for educators, as there are

Envisioning America & What Caused the Pueblo Revolt Essay - 7
Envisioning America & What Caused the Pueblo Revolt - Essay Example There was no meeting ground between them which finally ended in the Pueblo revolt. According to Mancall, ââ¬Å"Richard Hakluyt the elder, a prominent London lawyer, succinctly described the rationale for those efforts. After enumerating the varied rewards, he further stated three goals of colonization. 1. To plant Christian religion 2.To trafficks 3.To conquer.â⬠(p.1) Weber states, "Pueblos religious beliefs were more important than Apache raids or drought in causing them to revolt" (p. 22). In his review of Webersââ¬â¢s book Lorraine Coops writes, ââ¬Å"Primary sources also help the students to "get inside the heads" of people in the past--to try and understand individuals motivations and experiences from their perspective. Peeling away the layers of the colonial facade can help students discover both sides of the story. If our goal as teachers is to make history "real" to the students, then primary sources need to be incorporated into our work.â⬠The goal of the colonists was selfish. They did not arrive with friendly intentions. But something unexpected also happened which worked to the tremendous disadvantage of the American Indians. Mancall observes, ââ¬Å"When the Spaniards moved across the Atlantic, they became the first Europeans to unleash deadly diseases among the native peoples of the Americas.â⬠(p.5) The American Indians suffered exploitation from all ends, people starved and many thousands died of diseases, for which they had no immunity or medicines. Considering the Pueblo revolt: Is there any room for disagreement within each group? Did the Pueblos have cause to support the Spanish? Were there Spaniards who opposed the subjugation of the Pueblos (or at least the way(s) in which people told the stories of conquest and subjugation)? Would a common Spanish soldier relate the same story as a Captain? A New Mexican colonist and a Franciscan friar? No room for disagreement

Causes of Variation in Construction Projects
Causes of Variation in Construction Projects Literature reviews that of Variations and Variation Orders requires a comprehensive understanding of the root causes of Variations (Hester et al., 1991).Variations some of which are financial, design aesthetics, changes in drawings, weather, geological and geotechnical reasons. From the literature review, there were 53 causes of Variations identified and these Variations are mainly caused by the Employer, Consultants and Contractors. As shown in Figure 1, these causes of Variations were grouped under four categories: Employer related Variations, Consultants related Variations, Contractor related Variations and other Variations. These Causes of Variations have been identified by many researchers (CII, 1990a; Thomas and Napolitan, 1994; Clough and Sears, 1994; Fisk, 1997; Ibbs et al., 1998; OBrien, 1998; Mokhtar et al., 2000; Gray and Hughes, 2001; Arain et al., 2004). The causes of Variations can be categorized according to the originators (CII, 1990a; Thomas and Napolitan, 1994). The 53 causes identified from the literature review are also discussed below. A. Employer Related Changes This section discusses the causes of variations that were initiated by the Employer. In some cases, the Employer directly initiates Variations or the Variations are required because the Employer fails to fulfil certain requirements for carrying out the project. Change of plans or scope by Employer: Change of plan or scope of project is one of the most significant causes of Variations in construction projects (CII, 1990b) and is usually the result of insufficient planning at the project planning stage, or also i can because of lack of involvement of the Employer in the design phase (Arain et al., 2004). This cause the Variations affects the project severely during the later phases. Change of schedule by Employer: A change of schedule or master programme during the project construction phase may result in major resource reallocation (Fisk, 1997; OBrien, 1998). This is because time has an equivalent money value. A change in schedule means that the Contractor will either provide additional resources, or keep some resources idle in the construction site. In both cases additional cost is incurred. Employers financial problems: The Employer of the project may run into difficult financial situations that force him to make changes in an attempt to reduce cost of the project. Employers financial problems affect project progress and quality (Clough and Sears, 1994; OBrien, 1998). Proper financial planning and review of project cash flow would be effective in avoid this problem to from happening. Inadequate project objectives: Inadequate project objectives are one of the causes of Variations in construction projects (Ibbs and Allen, 1995). Due to inadequate project objectives, the designers would not be able to develop a comprehensive design which leads to many of Variations during the project construction phase. Replacement of materials or procedures: Replacement of materials or procedures may cause major Variations during the construction phase. The substitution of procedures includes Variations in application methods (Chappell and Willis, 1996). Therefore, an adjustment to the original contract value is required if there is a change in procedures. Impediment in prompt decision making process: Prompt decision making is an important factor for project success (Sanvido et al., 1992; Gray and Hughes, 2001). A delay in decision making may obstruct the progress of subsequent construction activities and that may eventually delay the entire project progress. Obstinate nature of Employer: A building project is the result of the combined efforts of the professionals. They have to work at the various interfaces of a project (Wang, 2000; Arain et al., 2004). If the Employer is obstinate, he may not accommodate other creative and beneficial ideas. Eventually, this may cause major Variations in the later stages and affect the project negatively. Change in specifications by owner: Changes in specifications are frequent in construction projects with inadequate project objectives (OBrien, 1998). In a multi-player environment like any construction project, change in specifications by the Employer during the construction phase may require major Variations and adjustments in project planning and procurement activities. B. Consultant Related Variations This section discusses the causes of Variations that were initiated by the consultant. In some cases, the consultant directly initiates Variations or the Variations are required because the consultant fails to fulfil certain requirements for carrying out the project. Change in design by Consultants: Change in design for improvement by the Consultant is a norm in contemporary professional practice (Arain et al., 2004). The changes in design are frequent in projects where construction starts before the design is finalized (Fisk, 1997). Design changes can affect a project adversely depending on the timing of the occurrence of the changes. Errors and omissions in design: Errors and omissions in design are an important cause of project to delays (Arain et al., 2004). Design errors and omissions may lead to loss of productivity and delay in project schedule (Assaf et al., 1995). Hence, errors and omissions in design can affect a project adversely depending on the timing of the occurrence of the errors. Conflicts between contract documents: Conflict between contract documents can result in misinterpretation of the actual requirement of a project (CII, 1986a). To convey complete project scope for participants, the contract documents must be clear and straight to the point. Insufficient details in contract documents may adversely affect the project, leading to delay in project completion. Inadequate scope of work for contractor: In a multi-player environment like construction, the scope of work for all the players must be clear and without uncertainty for successful project completion (Fisk, 1997; Arain et al., 2004). Inadequate scope of work for the contractor can cause major Variations that may negatively affect the project, and leads to changes in construction planning. Technology change: Technology change is a potential cause of Variations in a project. Project planning should be flexible for accommodating new beneficial Variations (CII, 1994b). This is because the new technology can be beneficial in the project life cycle, for instance, reducing maintenance cost of the project. Or new methods of constructions that reduce construction cost. Value engineering: Value engineering should ideally be carried out during the design phase (DellIsola, 1982). During the construction phase, value engineering can be a costly exercise, as Variation in any design element would initiate and leads to Variations to other relevant design components (Mokhtar et al., 2000). Lack of coordination: A lack of coordination between parties may cause major variations that could eventually impact the project adversely (Arain et al., 2004). Unfavourable Variations, which affect the projects negatively, can usually be managed at an early stage by paying extra focus in coordination. Design complexity: Complex designs require unique skills and construction methods (Arain et al., 2004). Complexity affects the flow of construction activities, whereas simple and linear construction works are relatively easy to handle (Fisk, 1997). Hence, complexity may cause major Variations in construction projects. Inadequate working drawing details: To convey a complete concept of the project design, the working drawings must be clear and concise (Geok, 2002). Insufficient working drawing details can result in misinterpretation of the actual requirement of a project (Arain et al., 2004). Thorough reviewing of design details would assist in minimizing Variations. Inadequate shop drawing details: Shop drawings are usually developed for construction work details for site professionals (Cox and Hamilton, 1995). As mentioned earlier with regard to working drawing details, likewise, inadequacy of shop drawing details can be a potential cause of Variations in the construction projects. Consultants lack of judgment and experience: Professional experience and judgment is an important factor for a successful completion of a building project (Clough and Sears, 1994; OBrien, 1998). The lack of professional experience increases the risk of errors in design as well as during construction. Eventually, this may affect the project quality and delay the project completion. Lack of consultants knowledge of available materials and equipment: Knowledge of available materials and equipment is an important factor for developing a comprehensive design (Geok, 2002). In the construction industry where material standardization is not common, the consultants lack of knowledge of available materials and equipment can cause numerous major Variations during various project phases. Honest wrong beliefs of consultant: Honest wrong beliefs may cause construction professionals to contribute poor value add in projects (Arain, 2002; Arain et al., 2004). Consultants, without having firsthand knowledge, may make decisions based on their wrong beliefs which would adversely affect the pace of the project. Consultants lack of required data: A lack of data can result in misinterpretation of the actual requirements of a project (Assaf et al., 1995; Arain, 2002). When there is insufficient data, consultants are prone to develop designs based on their own perceptions, which may not be what the Employer wants. Eventually, this may cause major Variations and affect the project negatively. Obstinate nature of consultant: In a multi-player environment like construction, the professionals have to work as team at the various interfaces of a project (Wang, 2000; Arain et al., 2004). If the consultant is obstinate, he may not accommodate other creative and beneficial ideas. Eventually, this may cause major Variations in the later stages and affect the project Negatively. Ambiguous design details: A clearer design tends to be comprehended more readily (OBrien, 1998). Ambiguity or Doubtfulness or uncertainty in design is a potential cause of Variations in a project. This is because ambiguity in design can be misinterpreted by project participants, leading to rework and delay in the project completion. Eventually, this may affect the project progress negatively. Design discrepancies (inadequate design): Inadequate design can be a frequent cause of Variations in construction projects (CII, 1990a; Fisk, 1997). Design discrepancies affect the project functionality and quality. Eventually, this can affect a project adversely depending on the timing of the occurrence of the Variations. Noncompliance of design with government regulations: Noncompliance of design with government regulations or policies would cost the project difficult to execute (Clough and Sears, 1994). Noncompliance with government regulations may affect the project safety and progress negatively, leading to serious accidents and delays in the project completion. Noncompliance of design with owners requirements: A comprehensive design is one that accommodates the owners requirements (Cox and Hamilton, 1995). A noncompliance design with the owners requirements is considered an inadequate design (Fisk, 1997). Eventually, this may cause Variations for accommodating the Employers requirements. This may affect the project adversely during the construction phase. Change in specifications by consultant: Changes in specifications are frequent in construction projects with inadequate project objectives (OBrien, 1998). As mentioned earlier with respect to changes in specifications by the Employer, this is also a potential cause of Variations in a project, leading to reworks and delays in the project completion. C. Contractor Related Variations This section discusses the causes of Variations that were related to the Contractor. In some cases, the contractor may suggest Variations to the project, or the Variations may be required because the contractor fails to fulfil certain requirements for carrying out the project. Lack of Contractors involvement in design: Involvement of the Contractor in the design may assist in developing better designs by accommodating his creative and practical ideas (Arain et al., 2004). Lack of Contractors involvement in design may eventually cause Variations. Practical ideas which are not accommodated during the design phase will eventually affect the project negatively. Unavailability of equipment: Unavailability of equipment is a procurement problem that can affect the project completion (OBrien, 1998). Occasionally, the lack of equipment may cause major design Variations or adjustments to project scheduling to accommodate the replacement. Unavailability of skills (shortage of skilled manpower): Skilled manpower is one of the major resources required for complex technological projects (Arain et al., 2004). Shortage of skilled manpower is more likely to occur in complex technological projects. This lack can be a cause for Variations that may delay the projects completion date. Contractors financial difficulties: Construction is a labour intensive industry. Whether the Contractor has been paid or not, the wages of the worker must still be paid (Thomas and Napolitan, 1994). Contractors financial difficulties may cause major Variations during a project, affecting its quality and progress and in some cases even the safety of the site is affected if there is an argument. Contractors desired profitability: Contractors desired profitability can be a potential cause of Variations in construction projects. This is because Variations are considered a common source of additional works for the contractor (OBrien, 1998). The Contractor may eventually strive to convince the project Employer to allow certain Variations, leading to additional financial benefits for him. Differing site conditions: Differing site condition can be an important cause of delays in large building projects (Assaf et al., 1995). The contractor may face different soil conditions than those indicated in the tender documents. Eventually this may affect his cost estimates and schedule negatively. Defective workmanship: Defective workmanship may lead to demolition and rework in construction projects (Fisk, 1997; OBrien, 1998). Defective workmanship results in low quality in construction projects (Arain et al., 2004). Even the Contractor bares the cost of the defective work, but this also may affect the project negatively, leading to rework and delay in the project completion. Unfamiliarity with local conditions: Familiarity with local conditions is an important factor for the successful completion of a construction project (Clough and Sears, 1994). If the Contractor is not aware of local conditions, it would be extremely difficult for him to carry out the project. Eventually, project delays may occur that end up with vital Variations in the entire design entity. Lack of a specialized construction manager: The construction manager carries out the construction phase in an organized way to eliminate the risks of delays and other problems. Lack of a specialized construction manager may lead to defective workmanship and delay in the construction project. Fast track construction: Fast track construction requires an organized system to concurrently carry out interdependent project activities (Fisk, 1997). When the public and private sectors have large funds and want to complete projects in a very short time, complete construction drawings and specifications may not be available when the contractor starts work (Arain et al., 2004).Eventually, this procurement mode may cause major Variations. Poor procurement process: Procurement delays have various negative effects on other processes in the construction cycle (Fisk, 1997). Occasionally, the procurement delay may cause an entire change or replacement for originally specified materials or equipment for the project (Arain et al., 2004). This may therefore cause a need for project activities to be reworked. Lack of communication: Detrimental Variations, which affect the projects adversely, can usually be managed at an early stage with strong and incessant communication. A lack of coordination and communication between parties may cause major Variations that could eventually impact the project negatively (Arain et al., 2004). Contractors lack of judgment and experience: The consultants lack of professional experience increases the risk of errors during construction (OBrien, 1998). This lack may cause major construction Variations in a project, when both Contractor and consultant could not identify or foresee the problems in the planning stage due to both parties are lacking of experience. Eventually, this may affect the project quality and delay the project completion. Long lead procurement: Procurement delays have various adverse affects on other processes in the construction cycle (Fisk, 1997). Occasionally, the procurement delay may cause an entire change or replacement for originally specified materials or equipment for the project. Delay in long lead procurement is a common cause of delays in building projects (Assaf et al., 1995). Honest wrong beliefs of contractor: As mentioned earlier with respect to honest wrong beliefs of the consultant, honest wrong beliefs of the contractor can also be a potential cause of Variations in construction projects. Contractors, without having firsthand knowledge, may make decisions based on their wrong beliefs which would adversely affect the quality and pace of the project. Complex design and technology: Complex design and technology require detailed interpretations by the designer to make it comprehensible for the Contractor (Arain, 2002). A complex design may be experienced for the first time by the Contractor. Eventually, the complexity may affect the flow of construction activities, leading to delays in the project completion. Lack of strategic planning: Proper strategic planning is an important factor for successful completion of a building project (Clough and Sears, 1994; CII, 1994a). The lack of strategic planning is a common cause of Variations in projects where construction starts before the design is finalized, for instance, in concurrent design and construction contracts (OBrien, 1998). Contractors lack of required data: A lack of required data may affect the contractors strategic planning for successful project completion, leading to frequent disruptions during the construction process. This is because a lack of data can result in misinterpretation of the actual requirements of a project (Assaf et al., 1995; Arain et al., 2004). Contractors obstinate nature: As mentioned earlier with regard to the obstinate nature of consultant, likewise, this can be a potential cause of Variations in construction projects. If the Contractor is obstinate, he may not accommodate creative and beneficial ideas suggested by others. Eventually, this may cause major Variations in the later stages and affect the project negatively. D. Other Variations This section discusses the causes of Variations that were not directly related to the project team. Weather conditions: Adverse weather conditions can affect outside activities in construction projects (Fisk, 1997; OBrien, 1998). When weather conditions vary such as the various monsoon seasons in Malaysia, the contractor needs to adjust the construction schedule accordingly. Occasionally, this may affect the project progress negatively, leading to delays in construction. Safety considerations: Safety is an important factor for the successful completion of a building project (Clough and Sears, 1994). Noncompliance with safety requirements may cause major Variations in design. Lack of safety considerations may affect the project progress negatively, leading to serious accidents and delays in the project completion. Change in government regulations: Local authorities may have specific codes and regulations that need to be accommodated in the design (Arain et al., 2004). Change in government regulations during the project construction phase may cause major Variations in design and construction. This can affect a project negatively depending on the timing of the occurrence of the changes. Change in economic conditions: Economic conditions are one of the influential factors that may affect a construction project (Fisk, 1997). The economic situation of a country can affect the whole construction industry and its participants. Eventually, this may affect the project negatively, depending on the timing of the occurrence of the Variations. Socio-cultural factors: Professionals with different socio-cultural backgrounds may encounter problems due to different perceptions, and this may affect the working environment of the construction project (Arain et al., 2004). Lack of coordination is common between professionals with different socio-cultural backgrounds (OBrien, 1998). Eventually, project delays may occur that end up with vital changes in the entire project team. Unforeseen problems: Unforeseen conditions are usually faced by professionals in the construction industry (Clough and Sears, 1994; OBrien, 1998). If these conditions are not solved as soon as possible, they may cause major Variations in the construction projects. Eventually, this may affect the project negatively, leading to reworks and delays in the project completion.
