Northern Lights essays

Northern Lights essays The book I decided to read for the assignment is The Northern Lights written by Lucy Jago. This book by Jago details the true story of Kristian Birkeland, the man who put his life aside to figure out the secrets of the Northern Lights. This book describes the Journey of six men who climbed to the tallest peaks of Haldde Mountain to record and study the aurora borealis. These Six men were; Clement Isaakson Haetta, Kristian Olaf Birkeland, Bjorn Helland-Hansen, Elisar Boye, Kristoffer Knudsen, and Sem Saeland. While spending six months during the fierce winter, the six men recorded data off of state of the art instruments like the anemometer, which was used to record wind speeds. Also used was a Barometer to tell whether the air pressure changed during the aurora shows, while the Hygrometer measured the air humidity. The most important instrument used though was the magnetometers, which was used to measure changes in the strength and direction and the Earths magnetic field. Birkeland hoped that these instruments would give them answers to many questions asked about the bright lights. Some questions they were hoping to answer were; are the lights accompanied by a crackling noise, could the lights make hair sta nd on end, did they touch the ground, did they occur during daytime? By the end of the winter Birkeland was convinced that his theory, that the force disturbing the magnetic field came directly from the sun in narrow beams of electrically charged particles called cathode rays, was correct. A British scientist once showed that cathode rays consisted of high velocity streams of negatively charged particles: electrons. Birkeland was convinced that the Sun put out similar rays and that these particles hit the magnetic field of the earth and followed the field lines down toward the poles, where they struck atoms in the atmosphere and the energy created by the collisions was ...

Forest Ecosystem and Biodiversity Definitions

Forest Ecosystem and Biodiversity Definitions A forest ecosystem is the basic ecologic unit in a particular forest that exists as home for a community of both native and introduced classified organisms.  A  forest ecosystem is  named for the primary tree species that form the canopy. It is defined  by all the collective living inhabitants of that forest ecosystem that co-exist together in symbiosis to create a unique ecology.   In other words, a forest ecosystem is typically associated with land masses covered in trees and those trees are often  classified by foresters into  forest cover types. Examples of just a few  broad names in North America are The northern hardwood ecosystem, the ponderosa pine ecosystem, the bottomland hardwood  forest ecosystem, the jack pine forest ecosystem and so on. The forest ecosystem is just one of a number of unique ecosystems including prairies, deserts, polar regions, and great oceans, smaller lakes, and rivers. Forest Ecology and Biodiversity The word ecology comes from the Greek oikos, meaning household or place to live. These ecosystems or communities are usually self-sustaining. The word usually is used because some of these communities can become unbalanced very quickly when detrimental factors occur. Some ecosystems, like tundra, coral reefs, wetlands, and grasslands are very fragile and very small changes can affect their health. Larger ecosystems with wide diversity are much more stable and somewhat resistant to harmful changes. A forest ecosystem community is directly related to species diversity. Generally, you can assume that the more complex the structure, the greater is its species diversity. You should remember that a forest community is much more than just the sum of its trees. A forest is a system that supports interacting units including trees, soil, insects, animals, and man. How a Forest Ecosystem Matures Forest ecosystems tend to always be moving toward maturity or into what foresters call a climax forest. This maturing, also called forest succession, of the ecosystem increases diversity up to the point of old age where the system slowly collapses. One forestry example of this is the growth of trees and the entire system moving  toward an old growth forest. When an ecosystem is exploited and exploitation is maintained or when components of the forest begin to naturally die, then that maturing forest ecosystem goes into declining tree health. Management of forests for sustainability is desirable when forest diversity is threatened by overuse, resource exploitation, old age, and poor management. Forest ecosystems can be disrupted and harmed when not properly sustained. A sustained forest that is certified by a qualified certification program gives some assurance that the forest is managed to allow maximum diversity while satisfying the managers environmental and economic demands. Scientists and foresters have dedicated their entire careers trying to understand even a small part of forest ecosystems. Complex forest ecosystems are extremely diverse, ranging from dry desert shrub land to large temperate rain forests. These natural resource professionals have categorized forest ecosystems in North America by placing them into forest biomes. Forest biomes are broad categories of natural tree/plant communities.

Critique OPEC website Essay Example | Topics and Well Written Essays - 1000 words

Critique OPEC website - Essay Example This essay discusses OPEC, that has been quite successful in presenting its case as a joint effort to protect its members from possible exploitation by industrialized countries. For this purpose, it has used several means of propaganda and its website www.opec.org has been quite effective in projecting the serious aspect of OPEC’s loquacious inducements of using oil as a tool of diplomacy, intimidation and restitution. The details and information that have been made available through this website is the sharp example of how fastidious OPEC is about its appearance or presentation to the entire world. A number of causes comes into focus of this essay. The list of reasons starts with restrained production policy of OPEC nations. These nations have the upward trend of oil production since 1999 and have added more problem to the economic crisis that raised its head in 2008 and is still continuing. Though the prices have again fallen to the almost less than one third of the peak val ue of US $145 per barrel but it’s the recession that is responsible for this fall rather than OPEC nations’ contribution towards economic partner to the world as whole. This essay not only analyzes impact and effects that OPEC have on modern oil market, but also researches possible promotional actions of it's website. OPEC website is one of the mouthpiece or better to say a means through the use of electronic media. In conclusion, the researcher states that the website has been developed quite efficiently in pursuing the goals of OPEC as a tool for information and image broadcasting.

Analysis and Evaluation of Current Curricula to Improve Student Coursework

Analysis and Evaluation of Current Curricula to Improve Student Learning and Success - Coursework Example nificant impacts to the overall development of the students both academically and socially, hence the need for the assessment and the need for simultaneous transformational within the institution’s curriculum. As such, this manuscript will assess the curriculum of Centervale University, and evaluate the diversity aspects of the courses, and thereby propose transformational measures, endeavored at improving diversity. The manuscript will look into the community college section of the institution. The college section’s mission is to produce competent graduates that are well acquainted with academic, as well as social aspects, suitable for the job market. The institution’s vision is to advance its courses that include sciences, arts and other courses while incorporating the social aspects that promote diversity to place them for employment (Lindsay & Blanchett, 2011). The document employs the Comprehensive Curriculum Assessment Plan (CCAP) model to review both the academic and other curricula aspects of the college, in its endeavor to improve diversity. From the assessment, various elements are critical within the organization. It is evident that numerous universities across the region (including Centervale build their curricula, with a key consideration of the local students. This aspect disregards the facts that, owing to development and expansion, these institutions ought to grow, thereby creating a significant gap for the diverse students they ought to enroll (Basit & Tomlinson, 2012). This creates significant challenges to the foreign students and gives unwarranted advantages to the locals. As such, the foreign students experience bias, and this elicits discrimination, and hinders diversity, as it is evident in Centervale University. The University of Centervale does not incorporate enough courses that promote the diversity through the open admission of its various schools. This has critically affected diversity and equally among its growing number of

Brown vs. Board of Education Art Exhibit :: Art Museum Exhibit Segregation

Black and White Walking into Krannert Art Museum, I experienced something I have never experienced before. That something was actually analyzing and appreciating artwork. I have been around artwork before and have looked at many times and I have enjoyed it but I have never really sat down with art to break it down and notice the little details that make it so powerful. Today I did at Krannert Art Museum while looking at their Brown vs. Board exhibit. I was able to break everything down and notice the details and by doing this I got a much more influential experience out of it. At first glance it is the colors in the room that jump out at you and draws your attention most but after really looking around you see the colorfulness isn’t the what the artist wants to attract your attention but instead on all of the black and white all over the room which fits perfectly with the idea the exhibit is trying to get across. This idea is that blacks and whites are equal and together, as Americans, they are much more powerful then when they stand apart as whites and blacks. As soon as I walked into the exhibit I noticed it had kind of an eerie aura to it. The lights were dim and there was a peculiar silence that was only interrupted about every ten seconds or so by a low, almost electronic sounding, humming coming from one of the distant rooms. Also, every so often the lights would flicker a little and between that, and the movie that was playing on the side wall switching between clips, it gave the room a very sporadic supernatural atmosphere. I walked into the two different rooms and two things caught my eye. The brightly colored flowers and people wallpaper on the left side of the first room, and the huge colored picture of Brett Charles Cook, on the left side of the second room. I noticed that this huge portrait was done using mostly blue and orange paint, which may have been a way for the artists to get the students there to connect with the painting or just to catch their attention.

Environmental Factors

Environmental Factors Heidi Wallen HSM/220 March 21, 2013 Environmental Factors The four external environmental factors are: economic factors, sociological factors, technological factors, and political and professional factors. The six internal factors are: organizational purpose, mission, and philosophy, Organizational planning, Organizational operations, Human resources, Technological resources, financial resources.Economic factors including knowing what financial resources the company has and where funding is coming from weather it is government funds, donated funds, fees for service, or other agency income. Sociological factors include understanding community demographic both in terms of client and community. Understand the makeup in terms of income, education, gender, age, and other demographic factors. Technological factors for human service agencies can understand how to use the equipment such as computer hardware and software as well as new treatment approaches.Political/prof essional factors include knowing laws and regulations from federal, state and local levels as well as a political climate, or the attitudes of community and local leaders and the general public towards the services provided. Professional factors in human services include being aware of licensing and certification standards; and staying in good working relations with these agencies. When looking at all four of the factors it is heard to say what would be the most important.They all have good value, but if I had to I would say that Sociological factors seem to be very important.

Organizational Purpose is to have the understanding of a mission statement and a vision that is intended to provide the logic and the organizing theme . human service agency believes in what it hopes to achieve and what services they will provide to achieve its mi ssion and the vision, goals that were set.Organizational planning is having a strategy and plan to identify were the organization ideally would like to be in a time frame such as five or more years. This takes some brainstorming and looking at available data so they are able to project future needs. Organizational Operations requires regular review and examination of the programs and services offered to make sure that performance is measuring up to expectations. Human Resources refer to the many functions that are involved in the supervision and management of the organization’s employees and volunteers.Staff requires a working knowledge of human resources law. Technological Resources can include support and consulting services, computer resources, financial management expertise, marketing and public relations expertise, and other technologies that may be used to support the work of the organization. Financial Resources requires a careful examination of budget documents to det ermine where the funding is coming from and what obligations the agency assumes in accepting funding from each of the various sources.

Women, Indian, And American Cultures - 969 Words

Childbirth Positions in Chinese, Indian, and American Cultures Culture is an enormous part of our lives. It can affect every part of our daily living from our health, nutrition, religious beliefs, and communication, to even how one is expected to think and behave. This paper explores various cultural beliefs on childbirth and specifically childbirth positions from three different cultures, Chinese, Indian, and American. The basic differences in cultures permeates one’s perspective on birth and is part of why certain beliefs and restrictions are present. How one brings new life into the world is steeped in traditions unique to each culture. The Chinese believe that during childbirth the mother should not cry out or scream during labor. This is due in part to their stoic nature which does not allow them to express or talk about their problems or feelings. If they do, they may bring shame to their family known as a â€Å"loss of face†. Screaming or crying out during labor may also cause interference from evil forces such as malevolent ghosts or spirits according to religious beliefs. Chinese women usually give birth in a hospital in either a sitting or squatting position (Queensland Govenment). In India, women in childbirth are kept isolated from others during the birth because it is believed to be impure and may pollute others. They are usually kept isolated for up to forty days after the birth with their baby. This helps protect the mother and baby from illness and evilShow MoreRelatedThe Roles Of American Indian Women851 Words   |  4 PagesPrior to Western colonization, American Indian women played an important role in their communities.
