Left And Right Brain Essays (668 words) - Cerebrum, Neuroscience

Left And Right Brain Psychology Right Brain, Left Brain The human brain is a miraculous organ. It regulates thought, memory, judgment, personal identity, and other aspects of what is commonly called mind. It also regulates aspects of the body including body temperature, blood pressure, and the activity of internal organs to help the body respond to its environment and to maintain the body's health. In fact, the brain is considered so central to human well-being and survival that the death of the brain is considered in many parts of the world to be equal legally to the death of the person. In the past fifteen years or so there has been a lot of talk of left brain and right brain people. Clearly their are misconceptions and truths about how our brain hemispheres operate. First of all the myth of the left brain and right brain theory. This states that generally people see the left hemisphere of the brain controlling logic and language and the right, creativity and intuition. In addition people differ in their styles of thought, depending on which half of the brain is dominant. Some people believe that most of what these notions state is farce. Next the article explores the history of this fascination of the left and right hemispheres of the brain.. It wasn't until 1962 when Roger W. Sperry began experimenting on certain aspects of the brain that contribute to the truth of the left and right brain theory. Sperry studied people who had undergone surgical division of the corpus callosum, the bridge between the two hemispheres. His studies showed that, an object placed in th e right hand (left hemisphere) could be named readily, but one placed in the left hand (nonverbal right hemisphere) could be neither named nor described. Doreen Kimura. Kimura developed behavioral methods which involved presenting visual stimuli rapidly to either the left or right visual fields. Another important method developed was dichotic listening which centered around the use of sound to study the hemispheres. Through these tests and the continual study the theory that the left brain controlled ended. Instead a new theory was born known as the two-brain theory. This said that at different times one of the two hemispheres would be operating. An example of this is that the right hemisphere is in control when an artist paints but the left hemisphere was in control when a novelist wrote a book. This theory failed because of one physical studies showed that people with hemispheres surgically disconnected could operate in everyday life. Also, research demonstrated that each hemisphere had its own functional expertise, and that the two halves were complementary. There are five pionts two each hemisphere. 1. The two hemispheres are so similar that when they are disconnected by split-brain surgery, each can function remarkably well, although quite imperfectly 2. Although they are remarkably similar they are also different. The differences are seen in contrasting contributions. Each hemisphere contributes something to every action a person takes. 3. Logic is not confined to the left hemisphere. Although dominant in the left logic is present in the right hemisphere. 4. There is no evidence that either creativity or intuition is an exclusive property of the right hemisphere. 5. Since the two hemispheres do not function independently, and since each hemisphere contributes its special capacities to all cognitive activities, it is quite impossible to educate one hemisphere at a time in a normal brain. Through my research I came to the conclusion that people are not purely left or right brained. There is a continuum in which the hemispheres work together in harmony. Often the left or right hemisphere is more active in some people but it is never the sole operator. We have a single brain that generates a single mental self. , but merely somewhere on the scale between left and right brain. Some of us are extreme left, few extreme right and most in the middle leaning left a bit (this is where I fell). Psychology

It Isnt About Luck

It Isnt About Luck You were lucky to have FundsforWriters to sell your books. I dont have that luxury. I hear this so much, in one version or another. First of all, there is no serious luck in this business. Its a matter of constantly putting yourself out there in terms of writing, publishing, appearing, working social media, fighting to be current, taking chances. There is no one right way or best way, only the way that happens to work for you at that moment in time. Frankly, I started FundsforWriters because I could NOT sell my mysteries. I wanted to be a writer and make an income from writing, so I figured any sort of reputable recognition could only help me in becoming a professional writer. As someone who loved stringing words, I walked through whatever door opened for me, wrote whatever might help me take one step further in my career. However, I had my conditions and parameters in who I wrote for and what I wrote and how I proceeded: 1) Markets had to pay. Even as a beginner, I recognized that being paid mattered not only in my pocketbook but also in the eyes of editors I pitched. They knew who paid and who didnt, and that mattered in their judgment of me. I wrote a column once for nothing, hoping to aid my resume, but after several issues, when the editor still could not afford to pay, I stepped away. And I learned that nobody cared that Id written that column. 2) I had to build and retain a following. I couldnt just write and build up credits. I had to have someplace to flaunt those credits (website, then social media) and some means to retain those people who read my work and liked it (newsletter). 3) Repetition matters. I wanted to become Google-able, which meant frequent and reputable appearances. If I wasnt on the first page of a Google search for my name, I strived to submit to enough magazines, websites, newsletters, and blogs to improve my search ranking. A book a year wasnt going to work. 4) Quality matters. Its a given that your writing quality matters, but be careful where you make your appearances. I wish I knew way back when what I know now about that. I wouldve been a tad more selective in some instances as to whom I wrote for. You might be new. You might be a struggling mid-lister. You might be seasoned and coming back into the fold, trying to remain pertinent. Fight to present yourself as strong, diligent, and reliable. Keep putting yourself out there, but dont give it away. People will respect you so much more.

K-12 and Technology Research Paper Example | Topics and Well Written Essays - 1500 words

K-12 and Technology - Research Paper Example The paper answers the question why technology sources in K-12 curriculums need to be referenced. Keywords: K-12, curriculum, technology, integration, reference. Why Should a Curriculum (K-12) Reference Technology Sources? The positive effects of technologies on student achievement are widely documented. The importance of integrating technologies into K-12 curriculums and their implications for student learning was described in abundance. Instructional technologies are altering the curriculum design landscape and have a potential to enhance the quality of knowledge and learning in K-12. However, not everyone agrees that K-12 curriculums should reference technology sources. Part of the reason is that the benefits of using technologies in the classroom are taken for granted, whereas the importance of having these technologies integrated into K-12 curriculums is either underestimated or simply overlooked.... This is probably because many teachers fail to estimate the scope of instructional technologies and their role in achieving the desired learning outcomes. Contrary to public beliefs, instructional technologies are not limited to computers. More importantly, no instructional technology is possible without a philosophy underlying it (Gulbahar, 2007). Apart from the fact that referencing technologies in K-12 curriculum is important for student achievement, it is also essential to effective technology planning. The latter is required to choose the appropriate technology and guarantee that the instructional program is adapted to fit in the available technology opportunities. Referencing technology sources in K-12 curriculum is a fundamental component of productive educational leadership and contributes to the success of instructional endeavors in K-12 classes (Gulbanar, 2007). Barriers to using technologies in K-12 curriculums have been extensively documented. The six barriers to accessin g and using technologies in K-12 curriculums include stakeholder attitudes, availability of technologies, technical support, stakeholder development, time, and funding (Hew & Brush, 2007). Teachers are either bound to limit the use of technologies in the classroom or must begin with simpler technologies. With the lack of technologies in classroom settings come other problems, related to the integration of these technologies with K-12 curriculums. Therefore, referencing technology sources in K-12 curricula is important to ensure their successful integration with the instruction and effective use in the classroom settings. It should be noted, that curriculum is one of the crucial

Macrowritten1 Essay Example | Topics and Well Written Essays - 1000 words

Macrowritten1 - Essay Example Real GDP (adjusted) is based on the prices of the products and services produced in a year that have been adjusted with inflation and deflation to perfectly predict the decrease or increase in production for comparison of the economic development from year to year. It is calculated in relation to price index of a given particular year (Experimental Economics Centre, 2006). For economic policy makers, real GDP hold enhanced importance compared to the use of nominal GDP. The inflation and deflation need to be considered while calculating the exact outcome of the economic performance of a country in a given year. This will depict the actual growth or decline in the performance of the economy and would help in formulating plans for future developments of the economy. It will also help the government in preparation of the fiscal policy. GDP is calculated only for the gross count of products and services that are purchased and sold with no difference between transactions that sums up to the well being and those that diminishes it. It assumes that every economic contract adds to well being but actually it is not so. GDP overlooks everything that occurs outside the sphere of monetized exchanges despite its significant contribution to well being. The crucial household performance and the sector of volunteer services are completely neglected. The significant contribution of the elder care, childcare and other home based tasks and volunteer works in the community are not taken into consideration in the GDP as those do not involve monetary transactions. When the non-market economy declines and the function shifts to monetized sector, GDP represents such activities as economic advancement. There is a rise in GDP temporarily, but the debt needs to be repaid as it becomes a burden for the economy. The GDP breaches the essential accounting principles by treating the exhaustion of natural capital as income, rather than as the decrease of an asset.

Issues and results of the second Vatican council Essay

Issues and results of the second Vatican council - Essay Example It opened under Pope John XXIII in 1962 and closed under Pope Paul VI in 1965. It was a response to the changing culture of the post World War II world and a call to the spiritual renewal of the church. Even after all these years, the results of Vatican II continue to be debated and it has its supporters and its critics. It remains a bone of contention for theologians and Catholics, as it is subject to various interpretations. Traditionalists see Vatican II as a departure from the earlier beliefs and practices of the church and condemn the break with the past. Supporters see it as a step in the right direction and as a much-needed move to bring the church in step with the modern world. The opposing positions show that â€Å"Its champions, in many cases, see it as having liberated Catholics from a long night of oppression, thus restoring to the people of God their rightful liberties. Its detractors blame it for shattering the unity and order of the church and introducing an era of co ntestation and doubt† (Dulles, 2003). However, whatever may be the stand taken, it cannot be denied that Vatican II ushered in a new era in the history of the Church and has far-reaching implications for practicing Catholics today. ... It can be seen as the decision of the Church to â€Å"throw in their lot with all the forces making for humanization and progress† (Dulles, 2003). As O’Malley (2003) points out, the language used by Vatican II is a marked departure from that of earlier Church canons. It rejects the authoritarian, judgmental style of the past for a speaking style which conforms to contemporary communication. By opening channels of communication with all people, including non-believers, Vatican II ensures that the Church retains its relevance as a political and religious force to be reckoned with in today’s multicultural, diverse society. A refusal to engage in dialogue would result is a fortress-like mentality and effectively isolate the Church from the affairs of the world. Such isolation would definitely be â€Å"to the detriment of the church's mission† (Dulles, 2003). Vatican II attempts to see that its message â€Å"is extended and broadened to the entire world† (Pope Paul VI Closing Speech, 1965). By proclaiming its readiness to enter into a dialogue, and remain open to diverse viewpoints, Vatican II ensures that the Church can be a legitimate participant in international deliberations and contribute to finding solutions to the problems which beset the world. The purpose of the dialogue is to express the Church’s solidarity with all men, including non-believers. This objective of Vatican II is reiterated by Pope Francis in his recent address to the Diplomatic Corps, in which he expresses his wish that dialogue will help â€Å"to build bridges connecting all people† (Pope Francis, 2013). Pope Francis’ â€Å"embrace of the world† is a true reflection of the spirit of Vatican

Overview of the Grace-Fo Satellite Mission

Overview of the Grace-Fo Satellite Mission The Gravity Recovery and Climate Experiment Follow-On: An Overview An artist depiction of the GRACE satellite configuration (Sharing, 2017) The field of remote sensing is continuously expanding and adapting to yield new information about the earth and its complex systems. Modern satellite technology has expanded to be able to monitor spatial and temporal variations in Earths global gravity field (Schutze, 2016). The ability to monitor the Earths geoid now allows scientists to understand changes in hydrological characteristics on the surface of the planet including ice mass loss due to climate change and sea level rise (NASA JPL, 2017). The Gravity Recovery and Climate Experiment (GRACE) and its follow-on mission represent the application of this new technology that is essential for obtaining new data about global mass redistribution. The GRACE-FO mission will offer benefits due its use of active sensors and new technological inputs, but with any satellite system, there will be sources of error and challenges in design and data usage. The first GRACE mission was launched in 2002 as a result of the combined efforts of the US National Aeronautics and Space Administration (NASA) and the Helmholtz Centre Potsdam German Research Centre for Geosciences (GFZ) with assistance from partner institutions of both leading agencies (Schutze, 2016). The primary goal of the mission was to provide a new model of Earths gravity field every 30 days (Schlepp et al., 2015). Two identical satellites comprise the system with one trailing behind the other by 220km in a sun-synchronous orbit (Wahr, 2007). The satellites fly in a low polar orbit of 450 km and, the system circles the Earth every 90 minutes (Schutze, 2015). Spatial variations in Earths gravity field lead to different accelerations in the two satellites and therefore, differing inter-satellite separation (Schutze, 2016). Therefore, the GRACE mission is different than many other earth observation satellite missions because it does not make measurements of electromagnetic ener gy reflected back to it from Earths surface. The distance between the two satellites serves as the source of data. Also, uniquely, the satellites are left mostly without intervention to their orbit unless they separate by less than 170 km and more than 250 km (Sheard et al., 2012). Illustration of the positions of the two GRACE satellites in response to variations in Earths gravity field; a)The two satellites pass over the ocean and neither is affected; b)The lead spacecraft encounters a change in gravity over the more dense land mass and pulls away from the trailing spacecraft; c)The lead spacecraft moves back over water but now the trailing spacecraft changes position in response to the greater pull of gravity over the land mass (Ward, 2003) The first GRACE mission was only planned to run for 5 years, but far exceeded this as it is now in its 15th year of operation. The batteries in each satellite are fatiguing and accurate data is increasingly available in more irregular intervals (Gà ¶rth et al., 2016). As a result, NASA and the GFZ created a follow-on mission to prevent data gaps (Schlepp et al., 2015). The follow-on was approved for launch in August 2017 and is known simply as the Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission (Schlepp et al., 2015). The primary objective for this mission is the same as the previous; to create monthly global gravity models for five years (Sharing Earth Observation Resources, 2017). The GRACE-FO mission will use some of the key sensor technology and overall design of the first GRACE mission, but will also include unique features. The same two-satellite design will remain but the inter-satellite distance will be reduced from 220 km to 50 km (Zheng and Xu, 2015).   Several very important pieces of equipment will carry over from the first mission to each of the GRACE-FO satellites but will see improvements in design. This includes a microwave instrument (MWI) dependent on Global Positioning System (GPS) technology. The MWI system measures the distance between the satellites centers of mass and slight changes in distance represent gravitational changes (Tapley, 2008). A very sensitive accelerometer meant to measure the forces acting on the satellites besides gravity including atmospheric drag will also remain (Tapley, 2008). There were previous accelerometer errors and satellite-to-satellite measurement errors that will be reduced by the lower altitude and up dates in design on the follow-on mission (Loomis, Nerem, and Luthcke, 2012). The microwave ranging system employed can measure the distance between satellites to within one micron or about the diameter of one human blood cell (NASA JPL, 2017). It is known as a KBR system because it utilizes microwaves in the K (26 GHz) and Ka (32 GHz) frequency channels (Jiang et al., 2014). Distance measurements between the two satellites are taken by monitoring the time of flight of microwave signals transmitted and received nearly simultaneously between the two spacecraft (Bao et al., 2005). Previously collected data and models created by scientists based on known gravitational differences linked to mountains and ocean trenches, the location of the sun, and the flow of the tides are compared to new measurements of the satellites to interpret gravitational changes (NASA JPL, 2017).   Also, the GPS unit on board is used in tandem with the MWI to be able to understand the gravity field below and can accurately assign capture time to data (Sheard et al., 2012). The accelerometer can then measure non-gravitational forces affecting the satellite as previously mentioned including atmospheric drag and solar radiation pressure (Schutze, 2016). These additional forces are then subtracted from measurements taken by the MWI. At the low altitude of orbit of GRACE comes changing solar radiation and large thermal disturbances to on-board instruments (Schutze, 2016). As a result, one improvement to the accelerometer on the GRACE-FO satellites will be placing the measurement digitalization unit in a temperature controlled area of the spacecraft to prevent temperature variation that can make data inaccurate (Christophe et al., 2015). The FO mission will include new technology known as a laser interferometer that will make measures that are at least 25 times more precise than the on-board microwave ranging system due to shorter wavelength usage (Sharingà ¢Ã¢â€š ¬Ã‚ ¦, 2017). The LRI uses an active transponder principle, which means that the weak incoming received (RX) beam to the trailing satellite is replaced by a strong local oscillator (LO) beam. The LO beam is then reflected back to the lead satellite by a Triple Mirror Assembly (TMA) which directs the beam and influences the amount of light returned (Fledderman et al., 2014). It also serves to effectively route the incoming beam around other important hardware pieces (Fledderman et al., 2014). The use of the new laser interferometer represents the first time an active laser ranging system will be operated between two spacecraft (NASA JPL, 2017). However, the microwave system will remain intact to ensure continuity of data from the first mission and the use of interferometer represents only a technology demonstration (Sharingà ¢Ã¢â€š ¬Ã‚ ¦, 2017). While some studies found the LRI technology could greatly increase the accuracy of gravity data, others found that there would be only moderate improvements in the accuracy models (Flechtner et al., 2015). However, seeing the results of the two systems as they operate simultaneously will create meaningful data for the planning of future of gravity field missions. The GRACE-1 mission allowed for new breakthroughs in the fields of hydrology, oceanography, glaciology, geophysics, and geodesy (Sharingà ¢Ã¢â€š ¬Ã‚ ¦, 2017). Since gravity is determined by mass, the GRACE systems have the capability to show how mass is distributed around the planet (Sharingà ¢Ã¢â€š ¬Ã‚ ¦, 2017). However, GRACE has and will continue to have no vertical resolution and can therefore, not distinguish between surface water, soil moisture, and ground water (Bolton and Thomas, 2015). Land surface models therefore allow for the disaggregation of Terrestrial Water Storage (TWS) data by separating these data into layers with known points of distinction (Bolton and Thomas, 2015). For example, in a study of the High Plains region of the US, the variability of snow and surface water were found to make insignificant contributions to TWS variability compared to groundwater and soil moisture changes (Ward, 2003). Therefore, removing moisture data known from previous studies of th e region allowed scientists to subtract these figures from the GRACE gravitational measurements to understand changes in groundwater levels over time (Ward, 2003). Over time, improvements in GRACE data processing have allowed for the detection of changes in TWS within 1.5 cm accuracies for a wide range of spatial and seasonal scales (Jiang et al., 2014). (Ward, 2003) Measuring changes in global mass distribution can help scientists across many disciplines. GRACE data has also been used to observe increases and decreases in the ice and snow masses of glaciers and changes to the solid Earth following seismic activity such as the Fukushima earthquake of 2011 in Japan (Flechtner et al., 2016). Ocean water elevation changes caused by the devastating 2004 Sumatra tsunami had an impact of the inter-satellite distance of the GRACE satellites and showed how oceanic mass redistribution can affect Earths gravity field (Bao et al., 2005). Due to the relatively low spatial resolution of GRACE data, it is more useful for monitoring large-scale terrestrial water changes such as in past studies of the entire Amazon Basin or India (Bolton and Thomas, 2015). Other applications include flood and drought monitoring for management projects and interventions (Bolton and Thomas, 2015).   For example, the US National Drought Mitigation Center uses GRACE data mont hly to generate drought indicators and monitor surface water changes (NASA JPL, 2016). GRACE data also allows for the study of changes in deep ocean currents by measuring pressure changes at great depths. Similar pressure changes in the structure of the solid earth can be studied as well (NASA JPL, 2016). Trends in TWS and water mass redistribution made possible from GRACE data from 2002-2013 (Bolton and Thomas, 2015) One of the benefits of an active satellite system such as the GRACE-1 and GRACE-FO compared to passive systems is that it can collect accurate data 24 hours per day because it creates its own source of electromagnetic energy (Schowengerdt, 2006). Also, the use of microwaves in the GRACE missions means that data is not affected by any type of cloud cover which often greatly affects accurate passive sensor data acquisition because the system only considers inter-satellite distance and GPS location for data retrieval. Active sensors dependent on microwave signals like on the GRACE missions are unique in their capabilities. The launch of the first GRACE mission allowed for data on earths geoid that was 100 to 1000 times more accurate than previous models could estimate depending on the region of the global under consideration (Ward, 2003). GRACE data has also allowed scientists to under the impact of global climate change based on mass redistribution of water around the globe in a comprehensive and consistent manner never previously achieved. With more accurate data from the GRACE-FO mission and the security of continued data creation, changes caused by climate change will continue to be monitored and planning for issues such as drought can be improved. However, compared to passive system data, the analysis of data is more complex and costly overall. The data output of the GRACE systems also requires a lot of manipulation and filtering to create meaningful datasets for a variety of disciplines. The microwave region of the electromagnetic spectrum is far from the visible region and therefore, the resulting data is also less intuitive for human interpretation (Schowengerdt, 2006). The raw data outputs for GRACE are just inter-satellite distance measurements and GPS data about satellite location (Ward, 2003). Therefore, improvements in satellite technology components alone will not improve the data created by GRACE. Improvements also need to be made to the many geophysical models used in data processing (Loomis, Nerem, and Luthcke, 2012). For example, a complete global depiction of the earths gravity field is only available every 30 days while forces such as tidal shifts can change on a minute-to-minute basis. This difference creates an issue in which short-term differences are lost or their impact is underestimated (Sheard et al., 2012). Therefore, understanding gravitational influences not directly linked to mass balance changes is essential. Models of gravity field anomalies on earths geoid created by comparing GRACE data from two different temporal scales (Ward, 2003) Models based on GRACE data are also limited by the noise present in the system data. This noise is linked to instrument errors, uncertainties in background models, and limitations in processing strategies (Siemes et al., 2013). In order to make meaningful measurements of mass changes on the earth using GRACE data, the noise of resulting models needs to be kept at a minimum, usually accomplished by applying filters (Siemes et al., 2013). However, when one problem is solved, another potentially arises. Filtering suppresses noise and blurs the signal, limiting the spatial resolution so much that part of the leak may affect nearby regions and cause errors in mass redistribution data (Siemes et al, 2013). However, more complex filtering methods have been developed to also minimize the blurring of data. Also, the spatial resolution of GRACE data is ultimately limited (Siemes et al., 2013). The spatial range for very accurate GRACE data application was 400km to 40,000 km for the first mission (Tapley, 2008). The strength of GRACE data therefore lies in an ability to monitor mass changes over time rather than to understand the water storage in one area at a specific time. However, there is potential for the lower altitude of the GRACE-FO mission and the LRI technology utilization of shorter wavelengths to allow for higher spatial resolution. The GRACE mission have shown that the use of active sensor technology on earth system satellite missions that utilizes microwave laser instruments and likely laser interferometers is incredibly efficient at understanding changes in earths geoid. With the launch of the GRACE-FO mission later this year, even more accurate measurements and greater understanding of mass redistribution of water around the planet will be possible. Despite the rapidly changing and unpredictable political climate of the United States government, the launch of the GRACE-FO mission seems undeterred and the collection of important data related to climate change-related issues will continue to be gathered.

Irony in Oedipus the King Essay -- Oedipus the King Oedipus Rex

Irony in Oedipus the King      Ã‚   When Sophocles wrote Oedipus the King, he knew that his audience would have some idea as to the outcome, his tale being a Greek tragedy which follows a strict form. Not wanting to write a predictable, bland play, Sophocles used this knowledge to his advantage and created various situations in which dramatic irony plays a key role. Dramatic irony is present when the tragic truth is revealed to the audience before it is revealed to the characters within the story. Through this use of irony, Sophocles succeeds in telling a fresh tale. Even though the audience knows how the story will end, they are intrigued by the presence of irony. By crafting irony into his tale, Sophocles gives the reader a desire to see how Oedipus is going to mentally react to the events that are sure to transpire.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Oedipus is self-confident, intelligent, and strong willed. Ironically these are the very traits which bring about his tragic discovery.   Because of these traits Oedipus was able to solve the riddle given to him by the Sphinx.   When this riddle was solved he acquired great popularity and power.  Ã‚   He was then challanged into a riddle of his own where he had to find out the truth of his past and the fate of his future.   By solving this riddle he lost all the power and glory, left to be exiled and become a beggar in another land.   If Oedipus had not been so determined to escape and prevent the prophecy by the Oracle, he would not have fulfilled it. Possibly, he was doomed to fulfill the prophecy because he believed he could avoid it. Nevertheless, his fate was sealed by his actions of pride and determination. His pride of conquering the Sphinx led him to the marriage of Jocasta, his mother. Whe... ... truth, whereas when he blinded himself he knew the full truth of what the oracles had said. Sophocles successfully attained his objective in "Oedipus the King" through the use of dramatic irony.   Works Cited and Consulted: Abrams, M. H. A Glossary of Literary Terms, 7th ed.
