This is one of the reasons why music/sound therapy has become an increasingly popular method of addressing the problem of stress caused by environmental sounds.Advertising We will write a custom essay sample on Mrà ¡zovà ¡ and Celec specifically for you for only $16.05 $11/page Learn More However, it must be questioned what aspect of music/sound therapy actually contributes the most towards a better mental state. In certain cases it has been shown that the higher the decibel level of the ambient noise produced (applied through music/sound therapy or even through the general environment), th e greater the adverse impact on the human body. This means that just because a person plays loud music to counter the ambient environmental noise does not mean that this constitutes proper music/sound therapy. It is based on this that this study will examine two characteristics of music/sound therapy, namely sound and rhythm. This study assumes that sound, while an important component of musical therapy is supplanted in its level of importance by rhythm due to the ability of the latter to induce positive psychological reactions. Reasons behind the use of Sound Therapy From the point of view of Maguire, daily sounds associated with human activity (i.e. ranging from the sounds of ship engines, the noise heard during the construction of a nearby building or the general environmental noise brought about by cars) can cause an adverse reaction in the human body (Maguire 947-961). This is one of the reasons why the term â€Å"noise pollution† came into being within the past 40 years or so due to the effect that loud environmental sounds had on the human psyche and body. As a result, prolonged exposure resulted in a continued deterioration of an individual’s mental and physical health to the point that it can cause significant health problems in the future. The O’Callaghan study which attempted to examine the problems associated with noise pollution stated that some of the common symptoms of sound induced psychological stress come in the form of higher levels of stress hormones as well as an increase in the amount of headaches a person gets (O’Callaghan 779-788). It can also have an impact on the body creating issues with a person’s blood pressure, heart rate and has even been shown in the most extreme cases to cause strokes in the individuals that have been exposed to adverse environmental sounds (O’Callaghan 779-788).Advertising Looking for essay on art and design?

This was evidenced by the study of Mrà ¡zovà ¡ and Celec which noted similar symptoms in animals that were in areas with high concentrations of predators and had to be constantly on guard against threats. (Mrà ¡zovà ¡ and Celec 1089-1095) Through such an analysis it can be assumed that if loud annoying environmental sounds can cause an adverse physiological and psychological reaction, then the reverse could also be true wherein soft, soothing sounds can create a positive physiological and psychological reaction (Mrà ¡zovà ¡ and Celec 1089-1095). Sound Sound, within the context of music/sound therapy, is the backbone of the process wherein through the use of soft and melodious music; a person is invited to enter into a state of complete and utter peace. Depending on the type of sound utilized, ranging f rom sound waves, singing, violin playing and an assortment of other types of sources, sound can induce different kinds of internal psychological reactions in a person. The study of Mrà ¡zovà ¡ and Celec, which examined the effect of sound waves on children, showed that when exposed to different types of sound, children were more likely to express different emotional states. It was determined that loud sounds often annoyed children while on the other hand soft and melodious sounds usually calmed them down. Not all sounds though are created equal in terms of their positive impact on a person’s psychological state. The music of Beethoven, Chopin, Mandel and other such composers supposedly help to calm the mind, however, the Abrams study stated that patients preferred the sound of gentle ocean waves, the soft strumming of a guitar or the sound of rain as a better method of relaxation (Abrams 114-119). The apparent basis behind these responses was explained by Abrams as being co nnected to the general rhythm and repetitiveness found in the sound of rain, ocean waves and the soft strumming of a guitar. Rhythm Rhythm, within the context of music/sound therapy, refers to the regulated movement of sound/music based on a series of successive strong and weak elements. In essence, rhythm refers to the way in which sound goes through a cycle of different beats, tempos and patterns to create a coordinated output. When applied to music therapy, various researchers such as Cutshall explain that proper rhythm applied in sound therapy induces a more therapeutic reaction as compared to merely exposing a person to an assortment of sounds (Cutshall 16-23).Advertising We will write a custom essay sample on Mrà ¡zovà ¡ and Celec specifically for you for only $16.05 $11/page Learn More What Cutshall is attempting to say is that the different types of rhythm evident in various types of sounds can create differing levels of psychological reaction s. This is one of the reasons why in the Abrams study the participants explained that they preferred the sound of rain, ocean waves and the soft strumming of a guitar as compared to the work of Beethoven, Chopin, Mandel and other such composers. It is the general repetitiveness of the rhythm evident in the aforementioned â€Å"nature sounds† that is more appealing to an individual as compared to the overly complex sounds evidently found in the music of Beethoven (Sekiya 1). This is not to say that any type of sound would work, rather, when it comes to music therapy soft sounds combined with an equally soft and steady repetitive rhythm seems to work better than overly complex music (Sekiya1). For example, the unique aspect of the song â€Å"Drifting† by Andy McKee is that even though he is merely using a simple string guitar he is able to derive a variety of different tones from a single instrument. There is no singing, no overly elaborate background music, no wailing, shouting, or cursing rather the entire song is the embodiment of simplicity with just one person plucking away at a single instrument. Yet, despite the utter lack of accompaniment the very texture of the song is vibrant, at times overwhelming yet calming. It distinguishes itself from other songs in that the melody is a combination of short plucking combined with idle strumming. It could be considered slightly repetitive due to the rhythmic quality of the plucking involved however this is accompanied by several incorporations of slight strumming which helps to break the repetitive quality of the plucking. It is this very repetitiveness that makes the song easy to remember and identifiable with a conjunctive motion that helps to develop its melodic quality and likeability. Doing a brief YouTube search of the song and merely listening to it is evidence enough of how simplicity in sound and repetitiveness in rhythm help to immediately calm a person down. Different Levels of Appreciation Before proceeding, it was determined that a brief overview should be done regarding the different types of musical appreciation out there and how this impacts the ability of a person to actually be affected by certain types of music therapy. First and foremost, different genres of music appeal to different listeners and different time periods in music appeal to fans from different time periods. Rock music was adopted by teenagers due to its apparent â€Å"shock value† to older generations due to the overtly sexual, anti-establishment and aggressive quality of the songs.Advertising Looking for essay on art and design? Let's see if we can help you! Get your first paper with 15% OFF Learn More Rock music was used as a means of distinction, a manner in which teenagers at the time defined themselves as being separate from the distinctions associated with older generations. As such, rock music composers followed this trend by composing songs in such a way so as to incorporate aggressiveness, anti-establishment and sexuality in the way the songs were sung or played. The reason rock music is mentioned is due to the fact that music created by Beethoven, Chopin and Mandel may not be as appreciated or liked by members of the current generation as compared to the previous generation (Rapoport, Eliezer and Blass 37-60). Thus, if such music is used in their music therapy sessions, it is unlikely that it would be as effective due to the lack of general appreciation the current generation would have towards the music (Rapoport, Eliezer and Blass 37-60). This particular piece of information helps to support the argument that focusing on rhythm instead of sound in music therapy is more important since sounds related to falling rain, ocean beaches and the light strumming of a guitar helps to cross the generational barrier resulting in more or less equal levels of appreciation. Conclusion The issue with high pitched, loud or otherwise annoying environmental sound has been determined by Maguire to be a form of stressor. This can be defined as an outside factor that impacts the ability of normal individuals to continue on with their daily tasks due to increased mental stress which can cause an adverse psychological and physiological reaction over the long term. The inherent problem with the modern day environment is that in most cases you cannot simply turn off the ambient environmental sounds off with a switch. The perceived physical and psychological reactions brought about by high levels of ambient environmental sound has been theorized as a holdover phenomenon from humanity’s evolution wherein perceived loud noises acted as an external trigger reaction towa rds a predatory presence. This is where sound therapy enters into the equation. Based on the findings of this study, it was shown that sound, while an important component of musical therapy is supplanted in its level of importance by rhythm due to the ability of the latter to induce positive psychological reactions. This shows that merely exposing a person to loud sound would be the same as noise pollution and, as such, music/sound therapy needs an appropriate rhythm to the music/sound that is being played to be effective. The reason why this examination was done was so that better processes in music/sound therapy can be created so as to improve the rate by which patients are helped.

Introduction to Sordaria Lab Report Essays

Introduction to Sordaria Lab Report Essays Introduction to Sordaria Lab Report Paper Introduction to Sordaria Lab Report Paper The lab experiment examined meiosis and genetic diversity through the model organism, Sardinia familial. Meiosis is part of the sexual life cycle and occurs in all sexually reproducing organisms. It is a method of cell division that produces gametes. Meiosis has two parts: meiosis I and meiosis II. Both parts undergo the same four stages of protease, metaphors, anapest, and Tallahassee. The process begins with one single parent diploid cell (that contain homologous chromosomes) that divides into four daughter haploid cells which each contain half the number of chromosomes that the original parent cell maintained. Both independent assortment and crossing over occur in meiosis I. Crossing over rearranges the DNA sequences that are then inherited and passed down to future offspring. This rearrangement, or recombination results in genetic variation within a species. The mechanisms controlling these crossover events are undefined. Recent existing evidence argues that harsh environmental pressures may lead to heritable changes in mechanisms controlling recombination. Much of this evidence has come from studies done at the Evolution Canyons in Israel. There are four Evolution Canyons, each of which consists of two mountain slopes with varying climates. Evolution Canyon I, located in Lower Inhale Orin, Mount Carmela, contains a south facing slope (SF) which experiences harsh climatic conditions, such as high temperatures and drought. The opposing north facing slope (NFG) is characterized by mild climatic conditions, including cooler temperatures and higher humidity. Evolution Canyon serves as a model for microinstruction and can be used to study how mutation and recombination contribute to adaptation and genetic diversity. The study published in the Genetics Journal and referred to in the logy laboratory manual studied whether there is a natural genetic variation for recombination frequencies and whether it correlates to environmental conditions and adaptation. The research was conducted on Evolution Canyon I and focused on the fungi organism, Sardinia familial. Several asexual filaments of S. Nicola were collected on different levels of each slope. The specimens were grown in the laboratory, where wild type spores from these crosses were then self-crossed to create a second generation of wild type spores. First, the filaments were grown on cornmeal agar with sodium acetate at 18 degrees and hen crosses were completed on minimal medium at 17. 5 degrees. Spontaneous spore color mutations appeared as non-black spores in the wild type strains. Also , the researchers plated the parenthetic (the fruiting body of the S. Nicola that contains acceptors) on growth medium containing sacrificial (a fungicide) and spontaneous sacrificial-resistant mutants formed. The strains were used to study varying mutation frequencies of wild type strains from the two different slopes on Evolution Canyon. Also, these strains were used to study the variations in crossover and gene conversion frequencies on the two opposing slopes. Their exults revealed that wild type strains from the SF experienced higher mutation rates than those strains obtained from the NFG. Although much less apparent, there were also slight differences in crossover frequencies within slopes. The results provide evidence that mechanisms controlling mutation and recombination may adapt heritable changes in response to the harsh climatic demands, particularly with the SF. Therefore, increased genetic diversity within a species may depend on the organisms environmental conditions. By understanding the factors controlling recombination, more can be known about genetic variation within a species.

Essential vs Non- Essential Job Finctions Research Paper

Essential vs Non- Essential Job Finctions - Research Paper Example On the other hand, non-essential job functions are duties that could be reassigned to other employees and effectively execute them (Hammonds & Kapusta, 2003). Some of the non-essential job functions include directing and escorting clients to different offices within the organisation. Employers are required to have knowledge of the employment provisions including disability Act. Essentially, employees are required to comprehend on essential job functions and how they affect employees. Disability Act Stipulates on the basic civil rights for persons with disability, women and the minority groups (Hammonds & Kapusta, 2003). However, an employer is not obliged to modify or eliminate an essential job function in order to accommodate person with disability. This is arguably true because an employee who is not in a position to execute the essential job functions even when considered to have a reasonable accommodation does not qualify for the said job and is not protected by discrimination
