Briefing a Case - Essay Example was an appeal against the decision of Erie County Court of Common Pleas. The lower court had denied the claimant negligence claims by from Pfeil Funeral Homes for the injury she sustained within the latter’s premises. The primary issues set for determination by the court of appeal were whether: a) the escort of the claimant by an agent of the defendant and his failure to warn her over the sharp drop on the public sidewalk was a matter of fact or law, and b) the junior court overlooked the facts about the case regarding the failure of the defendant to put a notice warning the guests of the risks of the eight-inch step down in the sidewalk. The Appellate court held that the issues of case were merely factual and not legal. As such the court affirmed the earlier ruling of the trial court, saying the claimant was not entitled to any negligence claims from the defendant. The court began by legitimizing the summary judgment of the lower court which it said was valid because: a) the issues in question did not meet the thresholds of material fact; b) the issues in question lacked the required basis in law to facilitate a fair, legal and reasonable verdict of the court and c) it would be unreasonable to impose any claims upon the defendant for the injury sustained at their premises because by doing so, the claimant would have gained more than she deserved while the defendant would have been unfairly disadvantaged by such a ruling. In addition, the court said the claimant would have been entitled to negligence claims if the statement of facts were supported by law. The court cited the precedent set in the case of Mussivand v. David (1989), 45 Ohio St.3d 314, 318, 544 N.E.2d 265, in which grounds for the awarding negligence claims arose. In the Musivand case, the court said that any negligence claims must meet three conditions: a) the duty of care owed to the claimant; b) a violation of the term, and c); the violation of the term being the proximate cause of the

Evolution of the Use of Wool and History of the Plow Term Paper

Evolution of the Use of Wool and History of the Plow - Term Paper Example The discovery of the plow also helped man in his activities such as farming. Science and technology has enhanced the improvisation of wool over the years thus keeping wool in the forefront of the rest of the fabrics. Wool has thus adapted to the modern standards in spite maintaining its previous features. It also takes a large part in the history of Britain. During the cradle of humankind around 1900 BC, weaving of wool into cloth became the main activity practiced. Domestication of sheep in the other areas started earlier (Lewis and John 1). Man soon realized that sheep produced milk and during the milking process, sheep shed its fleece, which made its acquisition easy and woven into cloth. Man discovered the several benefits he got from the sheep and thus decided to domesticate and rear it. Soon after domesticating sheep, man devised a way of getting cloth from fleece. He invented weaving and spinning the fleece into clothing. Man continued with the production of wool until it reached time where wool became the major export (Lewis and John 13). With time, the wool industry expanded a great deal. Exporting of wool increased and so did the manufacturing of wool fabrics and thus it became localized and specialized. Countries such as East Anglia and districts of Pennine had soft water, which makes the fabric more firm and compact surface. The Huguenot refugee weavers who sort refuge in France in the sixteenth century brought their weaving techniques with them and thus England surpassed Flanders in the wool manufacturing company and it stimulated the export rate. Introduction of machinery and mechanization in the industry of wool raised the standard of production of wool (Holsaert 105). This resulted into introduction of several other types of wool, which includes shape-Leeds, Bradford, Udders field, Halifax, and Wakefield. The sheep industry has greatly increased in the world. The natural coat of the sheep needed

Design And Construction Fundamentals Of Earth Dams Environmental Sciences Essay

Design And Construction Fundamentals Of Earth Dams Environmental Sciences Essay This paper focuses on earth dams, one of the oldest earth dams. Forming service reservoir for domestic water supply and irrigation purpose, earth dams comprise the most numerous class. The design and construction of Earth dams are complex because of the nature of the varying foundation conditions and the different properties of the materials available for the construction of the embankment. Last but not least, an understanding of the potential failure of Earth dams is important in the design and construction process of the Earth dams. Earth dams, also called earthen or earth-filled dams are generally built in or near drainage line which has the variety of purposes including domestic water supplies, agricultural irrigation, water for landscape improvement and others. One advantage of the Earth dams is because it can adapt to a weak foundation provided proper consideration is given to the foundation and design of the Earth dams. However, failure of any important part of the Earth dams such as seepage, structural and foundation will lead to the collapse of the whole dam. Types of Earth Dams Constructed as a simple homogenous embankment of well compacted earth, earth dams are classified as Homogenous Earth Dams, Zoned Earth Dams and Diaphragm Dams. A brief discussion of the types of dams is as follow: Homogenous Earth Dam is a kind of common earth dams which consist of two main components; the impervious to semi-pervious structure and the toe filter and the drain. The purpose of the filter and the drain is to provide a through way for seepage to exit the dam structure without causing erosion. This type of dam is usually built on an impervious foundation such as solid rock or clay. The next type of Earth dam is Diaphragm Dam. A diaphragm dam, can be used when there is no impervious layer below the dam and modification of the dam can be made to suit at an impervious layer. Besides, this type of dam is limited to a height of 8.0m in order to keep seepage forces at a safe level. Last type of Earth Dam is Zoned Dam. A Zoned Dam is known to be the most efficient use of soil as each material is used to its greatest potential. The slope protection protects the shoulder from erosion and wave action, the core retains the water and the shoulders stabilize the core. Lastly, figure 1 shows the 3 types of earth dams. Figure 1. Cross section of Homogenous Earth dam, Zoned earth Dam and Diaphragm Dams 2. DESIGN OF EARTH DAM Earth dam is built for the purpose of storing water and is made of compacted earth. It is usually more convenient when concrete is expensive and timber is scarce. 2.1 Foundation A site investigation should be conducted prior to construction so as to investigate the nature of the foundation. By knowing the actual foundation condition at site, the earth dam can then be designed according to it. A dam foundation is said to be adequate if it is capable of providing a stable support for the embankment under all condition of saturation and loading and that it provide enough resistance to seepage to avoid excessive loss of water (Bureau of reclamation 1987). According to Bureau of reclamation (1987), dam foundation can be generally classified into three types namely foundations of rock, foundations of coarse-grained material and foundation of fine-grained material. These foundations may need to be treated to stabilize any weakness as well as to reduce seepage. For instance, coarse-grained, pervious foundations present no difficulties in the matter of settlement or stability whereas a fine-grained, weak foundation is subject to settlement or displacement usually present no problem in seepage. Rock foundation on the other hand must be checked for erosive leakage and excessive uplift pressure. If such conditions exist, grouting to the foundation must be considered. 2.2 Soil Earth dam is usually built with clay, sand and gravel and hence is also known as earth fill dam. The type of soil used in the construction of an earth dam must be suitable to allow for optimum compaction as well to reduce seepage. Soil permeability is one of important criteria to be considered in dam design, seepage-confinement units, drainage and other structural elements (Goldin, AL Rasskazov, LN 1992). Seepage usually occurs in fine-grained soils such, with greater permeability, as well as in some coarse-grained soils (Goldin, AL Rasskazov, LN 1992). Higher frictional resistance and greater permeability in granular soils is the reason for its greater stability as compared to cohesive soils. Greater permeability permits rapid dissipation of pore water pressures resulting from compressive forces. 2.3 Embankment In determining the height of the embankment, it is necessary to allocate for a settlement between 5 to 10 percent. This is to prevent its height becoming lower than the spillway height (Figure 1) since settlement is unavoidable despite having a good compaction since air and water out are being forced out of the voids by the weight of the dam, hence causing consolidation (Shaw, R Smout, I 2009). During compaction, equal effort should be applied throughout the dam to prevent differential settlement. The minimum compaction effort should not be less than 95% of the Standard Maximum Dry Density (Department of Primary Industries and Water 2008). The stability of the embankment depends largely on its ability to resist shear stress which comes from internally applied loads such as the weight of the soil and the embankment slopes, and externally applied loads such as reservoir and earthquake loads. As mentioned earlier, steeper slopes can be adopted for granular soils since they are more stable. In contrast, a gentler slope needs to be applied for homogenous material with low permeability. Figure 1. Cross section of an earth dam 2.4 Spillway Spillway plays an important role in earth dam since it allows excessive water to flow without overtopping the dam wall. There are two types of spillway namely the cut spillway (Figure 2) and natural spillway. Figure 2. The position of a cut spillway In order to reduce water velocity and subsequently minimize erosion, a gentle slope for the spillway must be provided. However, for steep slope, loose stones or geotextile can be provided to reduce erosion. Apart from that, adequate capacity of the spillway must be provided to prevent overtopping and to enable the spillway to effectively handle run-off. 3. CONSTRUCTION ON EARTH DAMS Stripping Organic soil and vegetation must be removed from the area that will covered by the dam base. The removed organic soil are stockpiled and used on the downstream slope of the fill. Key trench Key trench which is also known as cutoff trench is excavated below the base of the fill to a minimum of three feet deep for dam with 10 to 12 feet height. The key trench is included in the dam design to secure the dam to the base material and to prevent seepage under the fill. Diversion tunnel Diversion channels are excavated before the dam can be constructed. This tunnel often lined with concrete. The tunnel is built around the dam construction area at one side of the valley. In the drill holes, explosive materials are placed and blasting will takes place. The soil or broken rock is then removed. The steps are repeated until the tunnel is completed. Figure : Building a diversion channel In Figure, after the dam construction is completed, the diversion channel is closed o allow the lake to begin filling. Figure : Closure of diversion tunnel Cofferdam In summer, the construction on diverting the river starts when the river levels are low. At the upstream of the upstream of the main dam construction area, small dam which is also called as cofferdam are built. It is built using earth-moving equipment. The cofferdam will acts as a barrier to the river and the water will flow to the diversion tunnels. The second cofferdam will be built downstream of the main dam construction area. At this area, the cofferdam will prevent the river flow to flow back into the construction area. Figure : Cofferdams act as barriers to the river Foundation Grouting Grouting consists of lines or a line of holes that are drilled into the dam foundation. The types of foundation grouting are curtain and consolidation grouting. Curtain grouting Curtain grouting consists of a single row of gout holes that are drilled and grouted in sequence by packer testing to the base of the permeable rock or to a depth that acceptable hydraulic gradients are achieved (Fell et al 2005). Based on Figure, primary holes are drilled first. The last hole spacing will normally be 1.5m or 4m, but also may be as close as 0.5m (Fell et al 2005). This approach allows control over the efficiency of the curtain grouting. Figure : Curtain and consolidation grouting (Fell et al, 2005) Figure :Grouting downstage with packer (WRC, 1981) Fill construction Earth dam is usually constructed from impervious material which is clay or clay-based material. The construction materials, taken from the surrounding area have to be placed and compacted horizontally in the fill. Dry soil are usually added with moisture and compaction equipment such as a sheepsfoot packer used to obtain the proper compaction. The construction started by filling the cutoff trench with well-compacted material and six inch layers is added until the maximum height is obtained. The top of the dam at the center of the draw is usually built 10 per cent higher than the design to allow settlement of the fill. Based on Figure, a riparian pipe is placed through the bottom of the fill and a frost-free valve is placed on the riparian pipe. This pipe and valve system function is to allow water to be released downstream to other water storage facilities during water shortages. Figure : Elevation view of dam 4. POTENTIAL FAILURES OF EARTH DAMS Potential failures of dams have always been great importance and much attention has been given to safety evaluation and research due to their disastrous effects. According to Fell, MacGregor, Stapledon and Bell (2005), 79% of Earth dams with less than 30m high suffer more failures than higher dams. This may reflect better design, monitoring and surveillance of larger dams. Potential failures of earth dam can be grouped into three categories: Hydraulics failure, seepage failure and structural failures. A detail discussion of the types of potential failure of earth dam is as follow: 4.1 Hydraulics Failure Hydraulics failure occurs by the surface erosion of the dam by water. Hydraulics failure is due to several reasons. One of hydraulics failure is overtopping of dams. Overtopping failure occurs when the level of the reservoir exceeds the capacity of the dam. According to Fell, MacGregor, Stapledon and Bell (2005), over-topping is one of the main causes of failure in Earth dams. Overtopping may also be caused by insufficient freeboard provided. Next, erosion of upstream force due to continuous wave action caused erosion of the dam. However, this can be avoided if the surface is protected by stone rip-rap and filter. The next reason is due to erosion of downstream slope by rain water. Although the downstream face of the embankment is not affected by reservoir water, it may get eroded by heavy rain flowing down the face of the dam, causing the formation of gullies and finally collapse of the whole dam. 4.2 Seepage failure Seepage failure is also known as piping failure. Seepage failures are generally caused by pervious foundation, leakage through embankments, conduit leakage and sloughing. All dams have seepage as the impounded water seeks path of least resistance through the dam structure and its foundation. If the surface seepage intersects the upstream face of the dam, erosion may occur which will lead to possible failure of the dam. Typical method used to control the quantity of seepage is rock fills installed at the downstream toe or gravel blankets to intersect the line of seepage before it reaches downstream toe as shown in Figure 1. Figure 1. Seepage through a dam or embankment with rock toe or gravel blanket. 4.3 Structural Failure Structural failure includes failure of the upstream, downstream slopes of the earth dam, foundation as well as cracking deformation and settlement of the dam structure that may lead to overtopping or seepage failure. Slides in Embankment occur when the slopes are too steep for the shear strength of the embankment material to resist the stresses imposed. Failure of this type usually cause by faulty design and construction. As for foundation failure, it occurs because of excessive pore water pressure which reduces the strength of the soil which it may not be able to resist the shear stresses induced by the embankment. Furthermore, damage caused by burrowing animals lead to structural failure. This causes seepage water to flow out quickly, carrying fine materials along which consequently leads to piping failure within the structure of the dam and finally lead to a complete collapse of the dam. 5. CONCLUSION

Feminism and Masculinity Essay -- Manhood Hegemonic Masculinity

In contemporary society, hegemonic masculinity is defined by physical strength and boldness, heterosexuality, economic independence, authority over women and other men, and an interest in sexual relationships. While most men do not embody all of these qualities, society supports hegemonic masculinity within all its institutions, including the educational institute, the religious institute and other institutes which form the ideological state apparatus. Standards of masculinity vary from time to time, from culture to culture. However, masculinity always defines itself as superior and different from femininity. For example, gay men and househusbands exemplify "subordinate" masculinities in our culture. They are not considered to be "real men". And yet, many still support hegemonic masculinity, for example, men being the main breadwinner for the family. Easthope (1990) states that, â€Å"masculinity tries to stay invisible by passing itself off as normal and universal† (Easthope, 1990: 1). The notion of masculinity tries to become a norm in society so then its counterpart, femininity is seen as different and deviant. Against this backdrop, femininity is constructed around the adaptation to male power. Its central feature is attractiveness to men, which includes physical appearance, suppression of "power", and nurturance of children, heterosexuality, sexual availability, and sociability. Masculinity and femininity are societal euphemisms for male dominance and female subordinat...

Effectiveness Ultrasound Tens Osteoarthritis Knee Health And Social Care Essay

Knee degenerative arthritis is perceived as the most common and unsafe degenerative arthritis. Besides, this is referred to as the most common cause of disablement in the United States of America, ( Eustice 2008 ) . Knee degenerative arthritis is a state of affairs consequential from weakening of articular gristle. Articular gristle is the soft coating whose intent is to cover the terminal of the leg castanetss where they convene underneath the articular gristle called Subchondral bone. Research has identified that articular gristle deteriorates due to a figure of factors including but non limited to ; old articulatio genus hurt, insistent strain on the articulatio genus, breaks, ligament tear, and muscular hurt which can impact alliance and promote wear and tear. Geneticss which make some people more likely to develop articulatio genus degenerative arthritis and jobs with subchondral borne or the bone bed underneath gristle. Research besides unfolds that of articulatio genus degenerative arthritis develops bit by bit and its symptoms include ; hurting which is moderate, mild or terrible, stiffness, limited scope of gesture in the articulatio genus and localised puffiness. Most research findings indicate that articulatio genus degenerative arthritis can non be cured but that there are interventions available which can be applied to pull off cut down the symptoms. These reportedly include ; medicines with Datril, non steroidal anti-inflammatory drugs and opioid analgetic medicines availed to those who need strong stronger hurting alleviation. Scientists use X raies to name knee OA is said to be the lone particular trial required in most instances. Trans-ceutaneous nervus stimulation or curative ultrasound ( US ) has been discovered to be so reactive in advancing effectivity of exercising on hurting, map, musculus strength and quality of life for articulatio genus degenerative arthritis. Research by pupils in United States of America unfold that 40 five patients with the articulatio genus OA diagnosing were consecutive divided into three random groups. Those in the first group were exposed to trans-cutaneous electrical nervus stimulation with superficial heat and exercising ; their opposite numbers in the 2nd group reportedly received ultrasound with superficial heat and exercising ; Group three acted as controls ( ace heat and exercising ) . Research unfolds that result steps were so included as ocular parallel graduated table, a 20 metre walking trial ; lequesne index, WOMAC shops ; isokinetic musculus proving. After this, in all intervention groups, physical modes were reportedly carried out for 15 Sessionss. Treatment groups were subjected to six hebdomads of exercising plan. FOCUSED CLINICAL Question: Does trans-cutaneous electrical nervus stimulation or curative or extremist sound addition the effectivity of exercising for articulatio genus degenerative arthritis? SUMMARY OF SEARCH: ‘Best Evidence ‘ appraised, and Key Findingss: Two articles were selected to supply best grounds about the subject. The first article is by Vladimir ( 2010 ) and it describes TENS as one of the most normally used electro analgesia and that 100s of clinical studies exist refering the usage of TENS for assorted types of conditions including that of Osteoarthritis. However, the really article unfolds failings involved in utilizing TENS and these include: It should non be used in patients with a pacesetter particularly of the demand type. Should non be used during gestation because it may bring on premature labour TENS is non applicable to carotid fistulas due to hazards of acute hypotension through a vasovagal physiological reaction. It should non be placed over anterior cervix because laryngospasm due to laryngeal musculus contraction may happen The electrodes should non be placed in an country of centripetal damage like in instances of nervus lesions, neuropathies ) where possibility of Burnss exist and TENS unit should be used carefully in patients with spinal cord stimulator or an intrathecal pump The 2nd article was extracted from plants of Brims ( 2009 ) who identified that much as TENS is good in alleviating hurting, it has some inauspicious effects among which are a possibility to go addicted in that it, a patient will hold to make more of the TENS in order to acquire to the same status. As an observation made, it has been identified that TENS is one and in fact the extremely recommended no medicative hurting alleviating agent of the musculuss non merely of the OA but even in the back hurting. At the same clip, it has been identified that TENS has got short approachs which I believe are in most instances ignored by doctors though obvious to them. If the usage of TENS does merely reduces pain but does non end or retard the acceleration of hurting to the extent that the expiration of application of TENS is the recommencement to further hurting, so it would non be recommended. Alternatively, it would be easier to use other agencies like articulatio genus replacing or any other possible options besides TENS and this would enable a patient to acquire alleviation from patronizing TENS and US activities. CLINICAL BOTTOM LINE: All the research findings identified show that articulatio genus degenerative arthritis is a strong infection without any agencies of remedy. However research findings merely identify that the status of a patient with Knee degenerative arthritis can merely be improved through usage of assorted drugs including but non limited to non steroidal anti-inflammatory drugs among many other drugs and application of trans-cutaneous electrical stimulation. On the same note, Brims ( 2009 ) identifies that taking pain medicine sums to decrease of the hurting but can be habit-forming and will construct up a tolerance in one ‘s system implying that a patient needs to take an increasing sum of the hurting medicine in order to acquire the same consequence. Pain medicine is said to extinguish hurting but is besides said to be impermanent and hence can hold negative long term effects. Cortsone trunkss can be every effectual at relieving the hurting brought approximately by terrible articulatio ge nus degenerative arthritis but it is said to merely be a impermanent hole and that the consequence will decline as conditions wear out. SEARCH STRATEGY: Footings used to steer Search Strategy: aˆ? Ultrasound which is referred to as a process that uses high frequence sound waves to see internal variety meats and produce images of a human organic structure ( Nucleus medical art 2011 ) aˆ? Trans-cutaneous electrical stimulation ; aˆ? Knee degenerative arthritis which is a status ensuing from impairment of articular gristle aˆ? The causes of articulatio genus degenerative arthritis. These can be traced from the causes of impairment in the articular gristle which include but non limited to old articulatio genus hurts and insistent articulatio genus strivings The effectivity of ultrasound and trans-cutaneous electrical stimulation in bettering articulatio genus degenerative arthritis as taken from a consideration of a randomized survey by Eyigor s. demoing how the effectivity of exercising for articulatio genus degenerative arthritis can be increased by trans-cutaneous electrical stimulation and ultrasound The difference between bettering articulatio genus degenerative arthritis hurting and bring arounding articulatio genus degenerative arthritis ; Harmonizing to research findings accessed, knee osteoarthritis hurting can be improved but non healed. The gradual procedure that is said to take to knee degenerative arthritis must be perceived as a non idiot able status in that when a simple break develops into articulatio genus degenerative arthritis, there are no opportunities of retrieving from the complication.

The aim was to analyse the research findings about the effectivity of extremist sound and trans-cutaneous electrical stimulation in relation to betterment in degenerative arthritis articulatio genus hurting by different research workers. Study Design ( including scenes and participants ) : The survey design was a success holding used the findings of Research by pupils in United States of America who unfold that 40 five patients with the articulatio genus OA diagnosing were consecutive divided into three random groups. Those in the first group were exposed to trans-cutaneous electrical nervus stimulation with superficial heat and exercising ; their opposite numbers in the 2nd group reportedly received ultrasound with superficial heat and exercising ; Group three acted as controls ( ace heat and exercising ) . Research unfolds that result steps were so included as ocular parallel graduated table, a 20 metre walking trial ; lequesne index, WOMAC shops ; isokinetic musculus testing ; and the short signifier 36. After this, in all intervention groups, physical modes were reportedly carried out for 15 Sessionss. Treatment groups were subjected to six hebdomads of exercising plan. These findings were compared with findings by other research workers about TENS which had unfavo rable judgments unveiling that TENS was non perfect as it hard some inauspicious long-run effects Result MEASURES: 1. When TENS and US are used to better conditions ensuing from Osteoarthritis, a patient improves but does non acquire healed. Harmonizing to some findings accessed, it has been identified that there are long term inauspicious effects alongside the usage of TENS hence TENS was non recognized as a perfect non medicative application towards OA by some writers yet it was recommended by others. 2. The effectivity of TENS was measured from research findings by some pupils which involved three groups of patients upon which TENS was tested and it worked 3. On the other manus, the ineffectualness of TENS was identified holding identified the long-run inauspicious effects alongside it. Consequence: 1. Amidst the surveies the findings accessed, it is difficult to believe that TENS and US can be used to absolutely better hurting of a patient with OA due to the inauspicious effects yet it can non be recommended to reason establishing on the findings that the experiment is good. What is of import nevertheless is to sensitise patients about the pros and cons of utilizing TENS and US so that it becomes their ain enterprises to take on the right place 2. On the other manus, it would be good if the usage of other drugs is promoted AUTHORS ‘ Decision: 1. â€Å" TENS and US can work efficaciously if done addictively but at the same clip it is good to educate the patients about the pros and cons of utilizing TENS and US before their application Critical Appraisal: ( Validity ) 1. Based on the experimnt by Eustice ( 2008 ) Trans-cutaneous electrical stimulation and ultrasound are so powerful in bettering the conditions of a patient with OA hurting However harmonizing to Daniel Sims, TENS should be applied sing the side long-run inauspicious effects? INTERPRETATION OF RESULTS: Comparing Eusten ‘s and Brims ‘ assertations and findings, the usage of Trans-cutaneous electrical stimulation should be to the right people, in appropriate conditions and establishing on right determinations Execution FOR PRACTICE: The deductions of the surveies and findings indicate that TENS being a powerful no medicative hurting stand-in can be used but the usage of drugs could be the top most precedence.

Population and economic growth Essay

It seems obvious that more rapidly growing populations have fewer natural resources per person, less physical capital per worker, more dependents, and greater needs for new social infrastructure. Perceptibly, they must be accounted as economically worse off. These intuitions shaped the earlier studies of population and economic development such as Coale and Hoover  model (1958). Later studies developed more neoclassical versions of these ideas, featuring that more rapid population growth led to per capita income. Noble prize economist Kuznets (1956), as well as Boserup (1956, 1981) and Simon (1981) suggested many possible positive effects of population growth, including economies of scale, acceleration of technological progress, flexible market response to emerging shortages , induces institutional changes , cheaper communication and transportation, and easier collective social investments. Kuznets examined per capita income growth and population growth rates across nations and found positive correlation, which seemed inconsistent with Koale – Hoover view. Their study was replicate by many others. In another advance, human capital was explicitly incorporated in growth model, and cross – national empirical analysis in the convergence framework indicated larger positive effects of population growth (Mankiw, Romer and W2EIL 1994). As Dawson and Tiffin (1998, p.149) put it that â€Å" the relationship between population growth and the economic development has long been thought to be fundamental to our understanding of less developed countries . Indeed most text book on economic development includes a section of population and development.† However there is no consensus whether population growth is beneficial or detrimental in the economic growth in the developing countries. As Thirwall (1994, p.143) commented â€Å"the relationship between population growth and economic development is a complex one and the historical evidence is ambiguous particularly concerning what is the cause what is the effect.† It is traditionally seen that the people of Bhutan are, by virtue of the circumstances of their habitat and precipice terrain, subjected to serious handicaps and constrained to scratch the earth for rather squalid and miserable living. The general impression in the minds of Bhutanese and foreigners alike who visit the nation is one of total abandonment and salutary neglect of the people. For most of the people of rural area, electricity, portable water supply, clinic, health centers and hospital which are by and large concentrated in the alleged urban areas, are just illusive luxurious. High proportion of the population still lives in the state of nature, by –passed by the modernizing influences and forces, which revolutionize traditional societies to progressive modern societies. The state of the life of the population kills its enthusiasm, dampens their morale and mitigates their sense of motivation and initiative. The scarcity  of these pre-requisites in the country is faced for the wanting of human capital that linearly depends upon the size of its Population. For this reason, it seems that low population growth rate of the country has, to large extent, been blamed for its state of affairs. Acrimonious debate regarding the economies and diseconomies of population has spurted between two schools of thought. One argument, presented by Clark and Ohlin, is in favour of unrepressed population growth based on the contention that it stimulates business and general economic growth cycles and therefore necessary for development. The other argument of Malthus is in favour of repressed population growth on the ground that unrestrained rise in population will mean less resources for individual members leading to considerable reduction in the euphoric life and well being of the people in that society, thus constituting an impediment to the socio-economic development of the society. The practical import of these divergent views is that positively or negatively, population question is intricately related to development which by all considerations is man –centered. Alluding to the positive and negative impact of rapid population growth, Ude asserted that â€Å"though there can be no development without human beings, any development that does not lead to overall increase in the welfare of the people is deficient. However, despite the merit of Malthus school’s arguments in favour of repressed population growth, the rapid population growth has unequivocally been a panacea in dealing with the problem of human capital whereby underdevelopment and poverty was in prevalent in Bhutan. Therefore Bhutanese in general should be sensitized to the realities of their abject miserable situation. Steps should be taken to mobilize the energies and efforts of the people to increase the growth rate of the population to the level that considered sufficient enough to beget human capital drastically needed for revolutionizing the economy through starting imminent developmental work with their help. In this paper, efforts are made to discuss the issue of population growth in Bhutan in its various ramifications. In the first place, the author takes the critical look at the deplorable economic conditions of the people. This is followed by an incisive examination of the implications of the phenomenon of population growth on the beleaguered economy. In like manner, the importance of the population growth, particularly in relation to the  generation of human resources and consequent development in the country are highlighted. Next, some suggestions and recommendations are made to ameliorate the economic conditions of the people, arising as a result of lack slow population growth rate in the country. METHODLOGY This is paper is based upon literature and theoretical evidences rendered by various school of economic thought. We have used Kuznets and W.W. Rostow model to explain the implication of population and economic development in Bhutan. In addition to this we used time series data for economic growth and population from the different issues of National Accounts Statistics reports of Bhutan, and population and census of Bhutan 2005. The State of Economy in Bhutan The plight to Communities in Bhutan is the focus of current discussions by many economists and a matter of concern for all levels of government in the Country. The picture of the country is described as being pathetic and the main features of the pre-requisites of economic development are found to be under-developed because of under utilization of its natural resources. In most areas in Bhutan, the basic infrastructural facilities which have been considered by W.W Rostow as prerequisites for development and tolerable human existence are generally lacking3. One of the pre-requisites of the well being of the community of any country is its roads. there are no functional roads for vehicles in rural areas and in some part of the country, roads construction work has not been yet started, thus leaving the people in those areas in dreary isolation from their own people and the rest of the World. The existing roads are also in deplorable condition. They are generally characterized by innumerable pot holes, deep enough to snap a car’s shockers or give the rim a terminal damage. The sad story of our rural roads calls for great concern when it is realized that over 70 percent of Bhutanese, as noted above, live in the rural areas and that it is from the latter that most of the food products of the country are derived. Without good roads, it becomes a big problem to send food products from these areas to the urban dwellers mainly depend on the rural folks for their food supply. Hence, every harvest season, thousands of rural farmers watch  helplessly as the crops which they cannot evacuate to the urban markets go waste, thus marginalizing their income from farm proceeds over the years. Being an agricultural predominated economy if it cannot able to produce exportable product, it must produce as much as food grain as is required by the countrymen. The irony of the Bhutanese economy is that all economists see it as rugged mountainous country which has less scope to produce that what is required by its people. They have made such impression Worldwide about this economy that nothing can sufficiently be produced here except remaining dependent on others for each and every thing. Moreover, the Bhutanese economy is suffering of the shortage of pre-requisites necessary for great spurt from backward economy to industrial economy. According to W.W.ROSTW, every developing country has to pass through a certain stages of development that he manifested as per-requisites of economic development. According to Gerschenkron, the existence of certain necessary conditions (pre-requisites) is not required for industrialization as is put forth by Rostow. He based this view on two empirical observations. First, the preconditions for industrialization that existed in England during its industrial revolution was virtually absent in the backward countries of Europe or existed on a very small scale. Secondly, big spurt of industrialization occurred even in those countries where they were not present at all. Without having adequate preconditions, these countries like Italy, France, Germany, and USSR (before 1985) had brought big spurt in their economy. Though they had not sufficient pre-conditions for great spurt, they had an adequate human capital because of high population growth to exploit natural resources and utilize them for generating precondition corresponding to industrialization period of these countries. Since Bhutanese economy is also passing through the same state of affairs by which the present developed nations were passing historically, it can also bring big spurt in its economy provided it should have its own sufficient human capital. This may be possible if it review its National population policy for stepping up its growth to meet the demand of labour force in the country. Population and Economic Growth: Many dynamic and active debates have been held regarding the impact of the increasing population on the economic development of the country since the  existence of the Malthusian theory. No doubt, an increase in the population in most of the countries has adversely affected the per capita output of the nation. Our empirical study related to the impact of population growth rate on economic growth has explored statistically very significant and optimistic findings in case of Bhutanese economy. The basic infrastructural facilities which are required, at the rudimentary development stage of the country, unfortunately found almost missing. This country needs stringent measures towards establishing more academic and vocational institution so that more academicians, engineers, doctors can be trained to enhance the pool of the human capital. Specialization in the works increase the quality and productivity of the labour and this probably be procured, if the country will have a well- versed pool of human capital. The massive group of the human capital will automatically enhance the economic growth of Bhutan. Development of the countries such as India and China are entirely impinging upon the human capital. Economic growth rate of these countries, since their independence, has grown very rapidly because of large group of human capital .Though these countries have suffered because of the high growth rate of population; they are progressing at high rate only because of innovations and technology, which in turn, depend upon the human capital which is linearly related to their population. India is enjoying the status of nourishing almost 16% of the total population of the World and economically stands fourth in the world based on purchasing power parity as per the World Bank report of 2008. Population is not the sole factor for slowdown in the economic growth of the country, but factors like political instability, corruption, inefficient managerial system, misallocation of resources, etc. are more responsible for it. As the Chinese proverb reflects that â€Å"Roads and railways lines are considered as the fate lines of the nation†, the government of Bhutan must pay attention towards the dissemination of the network of roads. Government needs to start some plans and projects to build railway track and Air routes through which tourist can be attracted within the country that will enhance the Foreign Cash Reserves. According to National statistics Bureau of Bhutan (2010), 69%of the total population of Bhutan is living in rural areas (205Gewogs -Bhutan at glance -2008) of the country. Most of the  villages are deprived of the basic amenities like road; safe water supply, education, regulated markets where the surplus product of the peasant could be marketed. There are only 29 hospitals with 145 doctors that are taking care of 6, 71083 people (Population and Census of Bhutan, 2005). It means that there are approximately one doctor per 5000 people that seem to be a very poorest ratio after Ethiopia and many others under developed countries of the world. There is a need for increasing the health related facilities in the country. Geographical conditions of the country become an obstruction in the way of the masses to avail the medical facilities in the hospital. Empirical findings show very dismal progress in the area of health. These entire problem faced by the people are ascribed to lack of human capital which could be solved by increasing the population of the country. â€Å"The economics of scale† phenomenon of population 1. Population and market structure Despite of the Malthus theory of diminishing return when it comes to scarce resource like food and water , some of optimistic population growth economist , like Kuznets (1956), Boserup (1981), believed that population growth can really help the nation economy to turn from ineffective economy into economies of scale state. According to Kendrick (1977), economies of scale are an important factor to increase the productivity of labour of a country. A country with rapid population growth can suffer many maladies like capital dilution, shortage of necessity resources and the causality could lead the whole population to poverty, famine and starvation. However, there are three arguments supported for the idea that population growth can boost the country economy by economics of scale phenomenon. Firstly, a nation, which has a rapid population growth rate, means that its population size will develop with a quicker rate. The bigger the population size is, the larger the market size becomes. In order to meet the product demand of the large –size market, bigger and more effective as well as longer performance period manufacturing plants are required to develop (simon, 1994). Countries in the world with larger population size like India and China are growing faster than any other country of the world because of their strong market network. Market base not only generate entrepreneurship among nationals but also causes induced foreign investment in the country. All developing countries like Bhutan need significant funds to expedite economic development programme for making provision of amenities required for higher living standard of the people of the country. The present state of economic affair of Bhutanese economy necessitates the expansion of market base to have an induced foreign investment and the generation of entrepreneurship among nationals to establish spectrum of industries in country to bring about industrial revolution. â€Å"All the developed countries of the present world were backward historically† (Gerschenkron 1947). Germany, Italy, USA, and England have achieved a status of advance industrialized countries, which were also backward in past, due to their strong army of human capital. Therefore, we can conclude that if Bhutan intends to be a developed country, it will have to acquire more human capital but that would be possible only if it increases its population. Population and specialized labour force Large size of the population not only expands a market structure but also possess an impressive number of labours. Because of the avail ability of the labour force it is possible for firms to divide their labor into particular division of labor to do specific tasks. An excellent example of specialization is car assembly line in which each division just takes responsibility of installing only one part of the car such as engine or car wheels. According to Adam Smith, â€Å"division of labor has caused a greater increase in production than any other factor. This diversification is greatest for nations with more industry and improvement, and is responsible for â€Å"universal opulence† in those countries†. Moreover, through specialization, working skill of labor force is likely to improve more quickly with learning-by-doing. Since a large size of population demands a tremendous number of products, these workers have more chances to improve their working skill. As a result, the average time spending for producing one unit of output have tendency to decrease more quickly than in smaller market-size. Correlating with saving producing time, the cost per one product is also deducted and firm is more efficient through specialization. Finally, the rapid population growth rate could cause a positive effect on communication and transportation. Transportation plays an important role in economic development. A good transportation system can help reduce  transportation cost and travel time. Along with high population growth rate, the increase in population density is inevitable. A dense population is likely to pressure the government to develop more in transportation system such as railroad, highways and road. Take China as an example, according to United Nations Population Division, in 1985, its population density was 110 people/km2 and the total amount of railroad was 52,000 km while in 2010, the total length of railroad is 91,000 km (increase 75%) and its population density is 141 people per square kilometer (increases 28%). Transportation improvement is surely a general trend for every economic development, but it is not deniable to state that the population density has a strong impact on number of construction of transportation. As Julian L. Simon stated in â€Å"The Ultimate Resource†, â€Å"population growth clearly leads to an improved transportation system, which in turn stimulates economic development†. Population and self reliant in food grain The falling trend in total arable land is a serious concern for the government of Bhutan .These appalling trend cannot be owed to an increase in population but to an occupation changes in the economy which inherited due the occurring structural changes via economic development as is put forth by Schumper . Since the economy has started growing, the corresponding sector of agriculture sector like service sector and industrial sector have also started developing whereby the agriculturist are induced to migrate from their agricultural occupation to service and industrial sector. When the land owner shifted from agriculture to service and industrial sectors, their land turned barren. Migration of the masses from their earlier main occupation to services and industrial sector must be considered as main cause of fall in arable land but not the pressure of population. we can emphatically favour the economies of population that if the size of the population had high, the size of arable land would not have decreased rather it would have increased. We corroborate our views with the help of classical economist hypothesis that â€Å"supply creates its own demand.† we can apply classical theory to endorse our theory that an addition to the supply of labour because of increase in population will exploit the latent natural resources of the country to meet their demands. An addition to labour force will not only exploit natural resources for their survival but also help in  filling the lag of supply of them to give impetus to the economic growth. Therefore, increase in population will not exploit resources and find new mode and means for the country but will also make this country self –reliant for food grains and many other things including labour force for which this country is totally dependent on other nations. In essence, development of the Bhutanese economy necessitates high growth of population. CONCLUSION The authors optimistically weaves fabric of hope that if the measures outlined above are emphatically implemented, the population itself will be brought to the optimum size and aligned to match its requirement in exploiting and utilizing the latent natural resources of the country for giving impetus to the economic development of the country. Structural changes of the economy via disseminating the spectrum of industrial base are not possible in wanting of human capital that linearly links with size of population of the country. The country’s overdependence for outsourcing all kind of works will dampen if the planners review its population policy to increase it to that level necessary for exploiting the latent resources required for economic development.
