Re replay the example - Essay Example New York: Sterling." , which I started reading, and as I proceeded a number of points became clear in my mind. But as I started knowing more about the subject, a number of questions came to my mind. To resolve those questions, I started looking for more stuff in the library. I wanted to know about the economic impact of global warming and how it affects agriculture, and while doing my search with the keyword "economic impact of global warming" I found this article; " Mendelsohn, R., Nordhaus, W. D., & Shaw, D. (January 01, 1994). The impact of global warming on agriculture: A Ricardian analysis.  American Economic Review. ,  844,  753-771." which opened new horizons of thought for me. A very clear account of the impact of global warming on agriculture is given in this article. Now I started to think how after all is it possible to stay prepared for global warming as it is a growing concern these days, and one should know the consequence of this phenomenon, in order to stay prepared. So I searched the library with the keywords "preparing for global warming". This time I found this very interesting article " Sanders, S. (January 01, 2008). Preparing for a warmer world.  Western City,  84,  1, 7-10." After reading this I have come to know that improving our environment is a collective effort of a society as a whole and everyone among us should play his/her role to accomplish the task of preparing for global warming. In my opinion, writing a report of the research that I conducted using library is very rewarding. I was of the idea that there is no need to learn more about how to use a library, but after writing this report I feel to emphasize the need to learn more about how libraries are built, and how to effectively use them for our own benefits. Libraries have a complete system of their own, and one needs to know the basics of using them. This not only improves our efficiency, but also increases the yield of our research

Health and Long Term Policies and Programs in the Asian Cultures Essay

Health and Long Term Policies and Programs in the Asian Cultures - Essay Example China was worried then that it may have too many children to feed but after twenty-five years, it is now worried that an aging population may have too few workers to provide care services. Health care costs for both China and Japan can be expected to rise exponentially as fewer workers are present within the system to provide for a growing population of older citizens (Kaneda, 2006). Further, the problem of AIDS will certainly be an issue perhaps to the level of some sub-Saharan African nations which have found AIDS to be a growing menace. Human trafficking and the sex trade certainly adds to the problem and while the issue may not be that critical in Japan, it certainly is on the horizon for China and some other lesser developed countries in the Asian region such as Thailand and Burma. The government policies of creating awareness, educating the masses and providing positive social support could certainly help improve the matter (ASIP, 2008). On the other hand, the problem of an aging population may be a more critical one for China due to the devastating economic consequences it can have for the country as it seeks to become the economic superpower of the world. While the government has started to allocate more funds for the care of the elderly, a lot remains to be done and as reported by Kaneda (2006), â€Å"The rate of increase in health care costs has already exceeded the growth of the national economy and individual earnings (Kaneda, 2006, Pg. 1)†. In such a situation, the coming demographic shift for China would only worsen the situation as a whole generation of Chinese reach the age of retirement. It has to be understood that the trend of an aging population is inevitable for many countries and may even become accelerated where mortality rates as well as fertility are declining. However, the governments of Asia are focusing on policies which are geared

Scripture Assignment Example | Topics and Well Written Essays - 2000 words

Scripture - Assignment Example The section ends with a detailed development of three topics from the Dei Verbum. How did the Church settle on the 27 books of the New Testament? The early Church was prompted to come up with the 27 books of the New Testament by a number of factors. These factors were of, religious, socio-political, or cultural nature. A combination of these factors compelled the early Church leaders, as it were, to come up with the list of authentic and authoritative books in the New Testament. These factors are: Gnosticism: This was a sect of heretical believers who posed a great challenge to the early Christians on the teachings of the church. The central view of the Gnostic scholars was that, the elect souls are divine sparks temporarily imprisoned in the physical bodies as a result of precosmic catastrophe, and as such, these souls have a natural knowledge (gnosis) of their origin and destiny, and this natural knowledge will lead them to salvation. As it can be deduced from this position, for th e Gnostics, there was absolutely no need of an authoritative body of knowledge or traditions that would serve as a condition for salvation. Some of the Gnostic scholars were, Basilides, Carpocrates, and Valentinus and Marcion. The early Christians, therefore, had to come up with an authoritative body of knowledge that contained the teachings of their founder, JesusChrist, and the apostles, that would serve as a guide for their followers and that would enlighten the Christians against the heresies and the fallacies of the Gnostics. Montanism was another heretical religious sect that prompted the formation of the New Testament in the early centuries of Christianity. This Christian movement was a charismatic movement that claimed to be a religion of the Holy Spirit, and it was marked by ecstatic outbursts. This sect claimed that this kind of ecstatic outbursts was the only true form of Christianity. To counter this heretical movement and its teachings, the early church came had to come up with correct teachings of the Church which would act as a guide for its adherents. This led to the formation of the 27 books in the New Testament. Apart from the heretical teachings that precipitated the need for the formulation of the authoritative teachings of the Church, another phenomenon in form of persecution of Christians, further, necessitated the need for the articulation of the authoritative teachings of the Church based on the teachings of Jesus Christ and the apostles. When the imperial police started persecuting the Christians and demanding from the the teachings of Christianity, it became necessary for the Christians of the early Church to determine the correct teachings of Christianity, from a myriad of other teachings that claimed to be the true teachings of Jesus Christ and the apostles. This circumstance, therefore, led to the formation of the 27 books of the New Testament that constitute the authoritative teachings of the Church. Settling on the 27 books in th e New Testament Having been influenced by the above factors, the early Church set out to assemble the Christian books that contained the authentic teachings of Christianity. And to distinguish between the authentic and the inauthentic Christian books, the Church employed four guidelines (How the New Testament Canon was Formed, online). These guidelines

One of Jesus miracle is to be born by virgin woman Essay

One of Jesus miracle is to be born by virgin woman - Essay Example Therefore, this is a miracle. If Jesus had been born into the world just like all other men, this would have had grave consequences since it would disqualify Jesus Christ from being the worlds savior. The virgin birth is so basic for the incarnation that it leaves no room for compromise. The bible states or implies that Mary (Jesus’s mother) was immune from the original sin. She was more so preserved from all stains of original sin. The original sin is normally removed by baptism, but in Mary’s case she was never subjected to the active essence of original sin. At the same time the state of original sanctity, innocence, justice i.e. Opposition to original sin was conferred upon Mary thereby excluding every stain and fault, depraved emotions, passions and disabilities pertaining the original sin. However, she was not exempted from the temporal penalties of Adam; that is from sorrow, sickness and death. The reincarnation of Jesus Christ therefore, demanded for a perfect human nature. His coming through the womb of a virgin was significant so that he could have a perfect human nature. The eternal Son assumed a nature, not a person in the incarnation. The nature is called the holy thing. Therefore, the virgin birth of Jesus is tenet to Christianity and Isl am, which holds that Mary miraculously became pregnant with Jesus Christ while still remaining a virgin. This is because the conception did not involve a natural father, and sexual intercourse or male seed implanted in her womb, but, instead brought about by the Holy Spirit.3 God sent angel Gabriel to Nazareth to a town named Galilee to find the Virgin Mary4. Mary, the mother of Jesus was pledged to have been married to Joseph5, a descendant of David, but before they could come together she became heavy with a child conceived by the power of the Holy Spirit6. Since Joseph, her husband, was a righteous

Global Logistics Assignment Example | Topics and Well Written Essays - 500 words

Global Logistics - Assignment Example Trucking transportation is suitable for relatively bulky goods and when there is need for faster and economical mode of transport. Marine transport is suitable for transporting bulky goods through water bodies when it is available and cheaper than air transport. Important factors for selecting any mode of transport above are availability, efficiency and cost. From the mining fields, the unrefined copper ore is transported by rail from the minefields to the facilities in Toronto where they get processed and smelted to extract copper for export. From Toronto the copper is transported by rail to CentrePort Canada, where the copper is transported by trucks to the Port of Churchill, an Arctic deep sea port. This sea port has air, rail and road modes of transport, and the closest connection of sea between Asia and the mid-West of North America.CentrePort Canada has one unique difference from the rest of the inland ports because of the vibrant operations of air cargo combined with rail and truck transport connections at James Armstrong International Airport.The Copper is then loaded at Winnipeg Manitoba port and Transported by sea to the port of Nanjing in China. From the port, the copper is transported by rail from the port Nanjing to BeijingAirport China. The expected transit time by ocean from Winnipeg to Nanjing would be about eleven days ( Bauhmol, 2013). The suitable incoterm to be used while transporting these goods is CIF because it is suitable for inland or waterway transport mode, and ensures that the seller is liable until the goods are delivered at the destination port.It covers many risks involved in water transportation in comparison to air transport. In China, electronic goods for export would be transported by rail from the companies of manufacture to Beijing International Airport. From the airport the goods will get transported out of China by Air to CentrePort in Canada, a leading port for cargo

History 1112 Essay Example | Topics and Well Written Essays - 250 words

History 1112 - Essay Example reatest of the social changes that occurred out of these contacts and interactions between the continents is colonization, where the Western/central Europe sought to colonize America and Africa, in search for resources, free labor and settlements (Prak, 41). Slavery is yet another social change that occurred, resulting to the shipment of Africans from their continent to Europe and America to provide the required free labor. A range of economic changes also took place as a result of these contacts. The first notable economic change that occurred following the contacts is industrialization, which was majorly promoted by the availability of labor and raw material which could easily be sourced from America and Africa and then shipped to Europe (Prak, 60). Infrastructural development is yet the other economic change that occurred as a result of the contacts, where the Europeans had to construct infrastructural facilities in their colonies both in Africa and America, as well as at home to enhance the transportation of labor as well as raw materials required by the established

Assessing ecosystem health Essay Example for Free

Assessing ecosystem health Essay The simple summary of the article is shown below.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Metaphors drawn from human health can be applied in environmental assessment at ecosystem levels; hence the concept of ecosystem medicine may also be appropriate in trying to understand the environment.   By using metaphors one can understand a difficult concept into more known terms since a comparison as to what is common in medicine and in ecosystem. Human use science but they employ art also in appreciating and studying things. As a necessary consequence of using arts or even science   errors in treatment could also happen as there could also be cased of false alarms in diagnosing the environment.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   But for a successful application of the medical concepts in ecosystem, there could be a need have a greater-defined taxonomy of ecosystems to afford a better correlations and analysis of the different variables involved in ecosystems. Taxonomy will allow more definitions of technical terms in ecosystems which could be used by scientists and scholars to make a thorough investigation and analysis.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The health status of ecosystems in turn could also serve a good barometer to assess the present status or health of the environment. This must be so since the better the ecosystem , the better the environment. Question: 2.    Write a review of Section 1 (p-15: Introduction) and also indicate important points which the author has talked about to be discuss in the paper; any critique; anything missing?   Any important information we get from this section?   Any interesting thing we get from this section, and do we really find it in the following section? The simple introduction is shown below.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The author is saying that whatever the ecosystem now suffers is partly caused by human activity.   He is using a metaphor to convey his message.   That the environment’s health must also be determined like that of a human individual.   Like a human being who is subject to stress, the author illustrates that the ecosystem also suffers from effects of various stresses.   He cited as examples of stresses the following: harvesting, introduction of exotic species, generation of waste residuals, physical restructuring, and even extreme natural events which affect the environment. Question 3.   Write a review of Section 2 (p-16: Ecosystem: a nebulous concept?)   What do we learn from this Section?   What has author tried to communicate and how successful he has been to communicate?   And also indicate the significance of this section related to this article, if you see any critique to this section then write it with a complete logic? Is ecosystem a nebulous concept?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The author is saying that while others my think that term ‘ecosystems’ may be indefinite of meaning   because   of difficulty of delimiting boundaries on the basis of conventional observations.   Ecosystems are not isolated, but intimately connected, or nested within adjacent or larger systems as seen in the continuum from rivers to lakes; from estuaries to the sea; from the sea to the worlds ocean.   The author agrees that for management and assessment, ecosystem constitutes a relevant macro-level unit for describing the environment (Rowe, 1961, 1989; Bird Rapport, 1986).   Ã‚  Ã‚  Ã‚  Ã‚     The author is very clear in describing the ecosystems as a dynamic, complex, and open systems that are in constant change over ecological, evolutionary, and geological time (Rapport Regier, 1992), and such they exhibit chameleon-like properties; that is, they might exist in a number of alternative forms, the particular composition being very much influenced by internal dynamics and by interactions with neighboring systems (Holling, 1985; Rapport Regier, 1992). Question 4.   Write a review of Section 3 (p-16: Towards an Ecosystem Health Model) what do we learn from this Section?   What has author tried to communicate and how successful he has been to communicate?   And also indicate the significance of this section related to this article, if you see any critique to this section then write it with a complete logic? The quest for understanding leads to quest for having health ecosystem.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The author is saying that in the quest for a more comprehensive understanding of the process of ecosystem breakdown and recovery, he has come to think that humans are engaged in some form of ecosystem medicine (Rapport et al., 1979).   He said that introducing the medical metaphor suggests that, like physicians, ecosystem practitioners are in need of systematic procedures by which to recognize illness, devise protocols to rule-in or rule-out possible causes, and prescribe treatment. (Rapport, 1992) (Paraphrasing made)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   When it comes to treatment, medicine suggests several options: following internal medicine, ecosystems may be treated by regulating the blood chemistry of the system; following surgery, ecosystems may be treated by wholesale physical and biological restructuring.   The latter may involve both removal of undesirable elements and introduction (grafting) of desirable ecosystem components. I should hasten to add that we are concerned here with the application of scientific methodologies developed in medicine in order to assess the state of ecosystem health.   In so doing I neither subscribes to the view that ecosystems can be considered as organisms (for clearly there are not not not not substantive differences in both the mechanisms and degree of integration as well as in the dynamics of these two systems) nor do I suggest.   (Rapport, 1992) (Paraphrasing made) Question 5.   Write a review of Section 4 (p-17: The subjective nature of health assessments) what do we learn from this Section?   What has author tried to communicate and how successful he has been to communicate?   And also indicate the significance of this section related to this article, if you see any critique to this section then write it with a complete logic? Subjectivity is employed in assessing the ecosystem.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The author is equating the subjective judgment used in health assessment as to what is being done in assessing the ecosystem.   He said that clearly, in many cases, the diagnosis and treatment of sickness also uses gut feel or hunches in addition to the scientific way..   Inevitably, there enters a degree of subjectivity in evaluating the health status of an individual or an ecosystem. (Rapport, 1992) (Paraphrasing made)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The author mentioned some ecosystem transformations that are made without recourse to societal values or limitations of scientific understanding and cited as example the demise of the forest downwind of a smelter.   Nevertheless, he admits that more frequently   social value-judgments and the limitations of science appear   to mix as a form of art.   The author gave as an example the conversion to plantations of radiata pine (Pinus radiata) of highly diversified indigenous forests in New Zealand, where there are opposing view between conservationists and foresters. (Rapport, 1992) (Paraphrasing made) Question 6.   Write a review of Section 5 (p-18: Early Warning Signs of Pathological Ecosystems) what do we learn from this Section? What has author tried to communicate and how successful he has been to communicate?   And also indicate the significance of this section related to this article, if you see any critique to this section then write it with a complete logic?   (This section should cover all sub sections of the main section, one by one) Early warning signs of pathological ecosystems have obstacles.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The author mentioned three obstacles in providing early warning of ecosystem pathology and they are: Firstly, basic processes such as nutrient cycling and primary productivity, is highly cyclical and irregular, varying from year to year, seasonally and diurnally.   Such variability and seemingly random behavior raises havoc with detection of the onset of much pathology that beset aquatic ecosystems. Secondly, early symptoms of ecosystem degradation may be missed or discovered only after pathology is well advanced. Thirdly, false alarms are easily sounded owing to a still far from adequate understanding of the long-term dynamic behavior of ecosystems. Ecosystems have common systems of degradation.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Under section 5.1 on â€Å"Health indicators at the ecosystem level,† the  author is discussing the identification of common symptoms of ecosystem degradation.   These common symptoms are termed the ecosystem distress syndrome (Rapport et al., 1985) and characterize a large number of ecosystems under stresses of various types.   The author citing Rapport, 1991, said that with reference to aquatic ecosystems, the ecosystem distress syndrome comprises the following symptoms: (1) alteration in biotic community structure to favor smaller forms; (2) reduced species diversity; (3) increased dominance by r selected species; (4) increased dominance by exotic species; (5) shortened food-chain length; (6) increased disease prevalence; and (7) reduced population stability. (Rapport, 1992) (Paraphrasing made) Like human diseases, ecosystems have risk factors, too.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Under section 5.2   on â€Å"Ecosystem risk factors,† the author   Ã‚  supports the idea of identification of individuals at risk for certain types of diseases, as those found in coronary disease, which will shift man’s attention from treating illness to prevention.   The author argues that using the same principle of identifying risk in ecosystem, prevention of the ecosystem’s degradation could be prevented. (Rapport, 1992) (Paraphrasing made)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   He believes that this approach works best where a single dominant stress acts to transform ecosystems, such as may occur in the process of eutrophication or acidification of aquatic ecosystems.   He said that much is known about the actions of these two stresses and the vulnerabilities of the recipient aquatic systems (e.g., Minns et al., 1990). He then argued that combining the findings from case studies of impacts of such specific stresses on ecosystems with the knowledge of current stress loadings and sensitivities of recipient ecosystems enables one to arrive at an ecosystem level risk assessment. (Rapport, 1992) (Paraphrasing made)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   He was able to cite the development of various factor analyses similar to the manner in which risks of coronary disease are now assessed in ecosystem health evaluations. He cited the work of Minns et al. (1990) who have examined the impact of acid precipitation on the loss of fish species in vulnerable eastern Canadian lakes. (Rapport, 1992) (Paraphrasing made)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   With these studies the author is really looking forward for the prevention of ecosystem’s degradation. Validation of treatment for ecosystem is a problem, too.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Under section 5.3 on â€Å"Validation of treatment† the author also talks of validation of treatment which is considered the bottom line for medical practitioners. This premised on the idea that once an illness has been diagnosed, the question turns squarely to the most effective treatment. Treatment validation provides a basis for selection among alternative procedures.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In applying the medical terminology to the ecosystem, the author said that success rates for a given treatment cannot be evaluated without factoring out the influences of the other stress factors. He cited an example the evaluation of the effectiveness of harvesting regulations on restoring seal populations in the Baltic Sea. He said that it is necessary to take into account impairments to seal reproductive success owing to the presence of PCBs and related toxic substances (Helle et al., 1976). Here, just as in human medicine, he said, â€Å"we have the need to develop methodologies to factor out co-morbidities.†Ã‚   He mentioned the need for a far better taxonomy of ecosystem ills than we presently have. He said that one currently may describe ecosystem pathologies in terms of air pollution damage to forests, eutrophication of aquatic systems, acidification of aquatic and terrestrial systems, etc. but he said that these are very rudimentary categories. He therefore suggested that for each of these classifications there are many finer subdivisions which need to be categorized before one can readily compare case histories. (Rapport, 1992) (Paraphrasing made) Question 7. Write a review of Section 6 (p-21: Reporting on the state of environment from an ecosystem health perspective) what do we learn from this Section? What has author tried to communicate and how successful he has been to communicate? And also indicate the significance of this section related to this article, if you see any critique to this section then write it with a complete logic? Environment could be seen from the health of the ecosystems.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The author is trying to make a picture of the environment on the basis of the status of the ecosystem. He cited Canada as having subdivided its land areas into 15 ecozones, defined on the basis of Physiographic, vegetation type, soils/surface materials, climate, and human use. He reported that the forests of most ecozones are impacted by a combination of natural and cultural stresses (particularly in the Montaine Cordillera, Boreal Shield, and Atlantic Maritime ecozones). Included in the stresses is fire, insects and diseases, over-harvesting, conversion of forests to agriculture, construction of transportation and utility corridors, air pollution, and climate-induced stresses such as red belt and wind throw.   He then cited the relationship of increase disease in ecosystems which are more stressed. (Rapport, 1992) (Paraphrasing made)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The author also mentioned that the other sections of the 1986 Canadian State of Environment Report relate to aquatic ecosystems, both the Laurentian Great Lakes and other Inland Waters, as well as the three marine systems (Atlantic, Pacific and Northern). He also cited that the major stresses affecting these ecosystems include: over-harvesting, construction of dams and diversions, contaminants (including toxic substances), and the purposeful or accidental introduction of exotic species (particularly in the Great Lakes and inland waters). Further, in all but the Northern marine ecosystems, land use change (particularly the drainage of wetlands for agricultural and recreational purposes) and sewage inflows added significant additional stress. (Rapport, 1992) (Paraphrasing made) Question 8. What do we understand from the Conclusions written on p-23, are they appropriate; any critique; any thing missed in conclusion; any thing over emphasized. The simple conclusion could be done as shown below.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   We understand from the conclusion that ecosystem behavior under stress is complex and processes leading to degradation and recovery are only partially understood, nonetheless, ecosystem medicine is coming of age at least as a conjectural art. There therefore many challenges along the way. There also a combination of objective and subjective criteria is called into play in rendering judgments as to the health of ecosystems.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Another thing that   I did understand in the conclusion is that in talking about assessing the ecosystem from a point of view need not involve or borrow concepts from the medical sciences to understand the system but that the author argues that use of the metaphor suggests more systematic approaches to the diagnosis and treatment of ecosystem ills, underscores the importance of validation of remedial action interventions, and draws attention to the inherent subjective nature of health assessments. Further, the metaphor provides a language in which the concern for ecosystem health becomes a natural extension of the concern for individual health The conclusions drawn are appropriate and does not in any way insist that understanding how to manage the ecosystem be necessarily made reference to the medical science field.   It could be made from different points of view and the advantage of using a field of study to bring out the issues via use of metaphor may contribute much to information campaign. Question 9.   Is this article helpful in planning and managing environment, if yes how?   If no, why? What is the relevance of the article in planning and management of the environment?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚     I believe this article is helpful in planning and managing environment.   Different persons belong to different professions and different professions have their own languages.   By using metaphor in medicine to discuss ecosystem and the environment, would be getting the member of the medical profession to understand the issues more clearly and to get their support for the cause of the environment Question 10.   Is the title appropriate, if yes WHY?   if no then suggest some other title, and also justify the title with a logical reasoning. How show the article be titled appropriately?   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The title evaluating ecosystem health seems not to include treatment on ecosystem treatment.   Since it talks also of treatment the title could be modified as â€Å"Evaluating and Maintaining the Ecosystem’s Health.†Ã‚   By simply saying evaluating it the discussion on treatment should not have been part.
