A Brief Note On Wealth And Income Inequality Essay

Wealth and Income Inequality in America: Bridging the Gap Wealth and income inequality in America has progressively gotten worse. The recession in 2007 did not help to reduce the gap between the two either. Wealth is determined by everything a person owns and income is determined by how much a person makes at their job. The better the job a person has, the more income they have and this helps to increase their overall wealth. Wealth and income inequality can be reduced by lowering the cost of higher education, implementing a progressive tax, working with one another to end the stigma of the color of one’s skin, deportation of illegal immigrants, and by putting an end to the gender wage gap. Reducing the costs associated with furthering one’s education would make it possible for anyone who wishes to further their education to do so. Most high paying jobs require the employee to have a degree of some sort. In many cases having a degree gives a person an overall advantage or edge when applying for a job. Some employers will forgo the experience over education because it can be viewed that the employee is dedicated because they made a serious commitment and took the time to further their education. Making college affordable for all would make it so everyone would have the same advantages in the job market. A person’s education determines their wages. The higher the education, the greater the opportunity to seek a higher paying job.

Test Incentives For Organ Donations - 1027 Words

No one wants to voluntarily sign up for an unnecessary surgery, which is why there is a five to ten year wait limit for an organ donation. The New York Times Article â€Å"Test Incentives for Organ Donations – There’s No Reason Not To,† written by Sally Satel, states that in order to raise the number of donations, people should be rewarded (Satel). Based on the statistics Satel provides, she says altruism is not producing enough donations. Instead, she believes the government should offer some form of incentive to lure people into doing a good deed (Satel). Satel’s article does develop solid points to teach readers about her topic effectively while simultaneously providing evidence to endorse her argument. She gets her purpose across by†¦show more content†¦She productively argues that not enough deceased donations will be enough to satisfy the wait limit (Satel). Satel’s purpose here is to let her readers know that patients in need o f a transplant do not have all the time in the world to wait for someone to save their life. She wants people to understand that waiting until death to donate organs kills others in the process of time. Not enough people die a day that actually qualify as organ donors to help the 100,000 people on the wait list (Satel). Satel uses this information as evidence as to why we need incentives for people to donate their organs; there is simply not enough willing participants that want to save another person’s life. Satel’s purpose was to inform readers of the crucial need of organ donors, which she believes can be solved by incentives (Satel). She managed this argument effectively by connecting the problem to someone’s reality while addressing the issue with practical evidence. Since her purpose was executed flawlessly, so was her evidence. Every new issue that was brought up had supporting information that validated it. She admitted that many people would assu me incentives for organ donations would just act as another way for the rich to feed off the poor. To counter that, she says, â€Å"the demographics of the waiting list indicate that recipients, themselves, are likely to be low-income† (Satel).

Bharatnatyam Free Essays

Introduction to Semiotics Bharatanatyam A journey from temples to the proscenium An introduction Bharatanatyam is a Sanskrit word, which means the dance of Bharata (India). True to its name, it is one of the oldest and most popular dance forms of India. It originated in the temples of Southern India and was later codified and documented as a performing art by the Tanjore Quartet. We will write a custom essay sample on Bharatnatyam or any similar topic only for you Order Now It is now the most popular Indian classical dance and is appreciated worldwide. Bharatanatyam is a language in itself. Like Sanskrit language, bharatanatyam follows strict rules and is technically sound. The grammar of the steps is followed rigorously. It is danced to Carnatic music and the mathematical precision of the dance equals the Carnatic music measure of measure. The three significant ingredients of bharatanatyam are: bhava (emotion), raga (music) and taal (rhythm); governed by Bharata muni’s Natya Shastra and Nandikeshwar’s Abhinaya Darpana. Hence, the interpretation BHAva +  RAga (music) +  TAla+  NATYAM(dance) =  Bharatanatyam. The technique and presentation â€Å"Bharatanatyam in its highest moment, is the embodiment of music in a visual form† -Balasaraswati The three major attributes of a Bharatanatyam performance are Nritta (technique), Nritya and Natya (drama). Nritta is pure dance. It is the movement of hands and feet on the rhythm and speed. It is a collage of rhythmic lines, forms and shapes. The movements, mudras or gestures do not signify anything. Then why nritta? Indian music and dance forms are based on the concept of cyclic rhythm or taal. Various musical patterns are woven with the musical notes and rhythmic patterns which can be beautifully executed through nritta. Nritya is interpretative dance. It is used to exhibit the underlying meaning of the song and the emotion attached with it. It is a combination of nritta and abhinaya or expressions. The meaning of the song is expressed systematic gesture language and facial expressions. Natya is equivalent to dance-drama. It is a language of gestures, poses, dialogues and mime. It depicts a story usually from the Indian mythology like Ramayan or Mahabharata. Here, the emphasis is majorly on abhinaya or expression rather than the rhythmic movements. The Abinaya is divided as: Angikabhinaya:  Expression through the limbs and body like the Head, Hands, and Legs. Vachikabhinaya:  Expression through narrations and voice. Aharyabhinaya:  Expression through dress, ornaments and other aids. Satvikabhinaya: Mental expression of feeling and emotion by facial expression and use of eyes. Bharatanatyam: The Journey The journey of bharatnatyam from the temples of south India to the proscenium of the world is a very exciting one. Dasi-attam (Origin and decline) Bharatnatyam as a very ancient and traditional art form has been associated with the temples of South India. It is believed that Bharatnatyam used to be known as the â€Å"temple dance†. Bharatnatyam was also known as the dasi-attam (dance performed by the dasis – the servants of God) or the sadir-attam (court dance). It was choreographed to be performed solo by the devadasis in the temples as an offering to the deities. These women, called devadasis, are said to have devoted their lives to God. They were considered to be united with the Gods. Infact, they were considered so close to the gods and so pure, that a pearl form their necklace was considered auspicious for the mangalsutra of a woman. They performed useful functions at temples like cleaning, lighting lamps, dressing the deities etc. They also sang devotional songs and danced in devotion to the deities. Apart from this, they taught music and dance to young girls. These devadasis were accomplished artistes who could play many musical instruments. They were well versed in Sanskrit and other languages, which helped them to interpret the compositions that they would perform. They were instrumental in developing a tradition of classical music and dance in South India. The devadasis were celibate and were not allowed to have a family as they were considered to be married to the Gods. Therefore, initially most of the dances in Bharatnatyam were choreographed to be in praise of God. Many padams (narrative pieces) depicted the love story of a nayak (hero) and a nayika (heroine). In most cases, the nayak was in the form of Lord Krishna, or Shiva or any other mythological hero. While Shiva was said to be serious, Krishna was full of pathos and love. Thus, the choreographies mainly concentrated on Sringara rasa (love). Gradually the devadasi system started getting plagued with several notorious ills. Around this time, it was customary for the Indian people hailing from royal or aristocratic families to invite a devadasi to a celebration, to sing and dance and perform. The best dancers were invited to the royal courts to perform, in return which they were provided with a shelter. In this period, the position of the devadasis could be compared to that of an apsara (celestial nymph) who danced in the courts of the Gods in order to please them. Eventually, the rich men and the aristocrats attracted the devadasis with good money and luxurious lifestyles and lured them into being their mistresses. The devadasis were easily enticed to the kind of lifestyle offered to them. Thus, the sringara rasa in their choreographies converted into eroticism and they danced merely to appease the rich men. As consequence of which, these devadasis who were held at par with the temple priests lost their respect in the society. By this time, the Europeans had arrived to India. Their advent was like addition of fuel to the fire of the already deteriorating dance form. The Europeans ridiculed this entire system of dancing to please the lords and considered this to be no better than prostitution. Under the British rule, propaganda prevailed to against Indian art, misinterpreting it as crude and immoral. Also other factors like loss of patronage due to the unstable political conditions, lack of recognition in the education system and lack of appreciation as compared to that given to ballet ; played a major role in the set back of the dance form. Due to the degenerated status of the devadasis, the Indian reformers started a movement against the devadasis. Thus the devadasi tradition was banned. The government started working with various non-governmental organizations to help reinstate these women into the society, as well as raise public awareness of the demeaning nature of their life work Thus, the devadasi tradition and with it the performing art (bharatanatyam) took a back seat in the history of Indian art and culture. Revival Against all odds, a few families preserved the knowledge of this dance form. These included individuals from varied backgrounds: Indian freedom fighters, Westerners interested in Indian arts, people outside the  devadasi  class who learnt Bharatanatyam, and  devadasis  themselves. The pioneers in reviving this art for are: E. Krishna Iyer, Rukmini Devi, Balasaraswati etc. Bharatanatyam now attracted young artists from respectable  Brahmin  families. Initially met with shock, their participation ultimately helped to shift public opinion in favor of reviving the art. An association of  devadasis  joined the effort to revive Bharatanatyam. Its ranks included an eventual teacher of Rukmini Devi’s, as well as the family of the legendary dancer Balasaraswati. Rukmini Devi’s debut performance in 1935 was a milestone. Her efforts won over much of the orthodox community of Madras. Her reforms of costume, stage setting, repertoire, introduction of dance drama,musical accompaniment, and thematic content, overcame the objections of conservatives that Bharatanatyam was vulgar. She went on to found the Kalakshetra institute, to which she attracted many great artists and musicians, with whom she trained generations of dancers. Balasaraswati promoted the traditional art of the  devadasis, maintaining that reforms were unnecessary and detracted from the art. Staying true to her  devadasi  lineage, she achieved great renown for her excellence. The renewed awareness of Bharatanatyam in Indian society allowed many nattuvanars  to resume their training activities, and many artists to enter the field of classical dance. Rukmini Devi’s desire to restore the full spiritual potential of the dance motivated reforms that led to what was known as the Kalakshetra style of Bharatanatyam. Bharatanatyam soon became the most widespread and popular of the Indian classical dance forms. It wasn’t long before it achieved international recognition as one of India’s treasures. Rukmini Devi versus Balasaraswati Differences in the similarity of trying to revive the Indian traditional art form The two towering figures that played a major role in the revival of das-attam as bharatantyam: Tanjore Balasaraswati and Rukmini Devi. Balasaraswati was affiliated with the school known as Tanjore court style while Rukmini devi was associated with a style that she developed at Kalakshetra. By focusing on these two dancers, we can throw light on the historical event of the upgradation of bharatanatyam. They were contemporaries. Balasaraswati gave her first performance in 1925 in a temple and Rukmini Devi gave her first performance in 1935 for the Theosophical Society’s anniversary celebration. Both performed Bharatanatyam regularly on concert stage and considered it a means of salvaging the endangered dance form. In the Indian dance world, both of them are legendary figures. Their names have become synonymous to classicism and traditionalism. Around both of them instructional communities have developed, which led to idea of development of various styles in Bharatnatyam. They led on to take Bharatnatyam on a whole new international level, in their own way. Despite the similarities and the oneness in the agenda of working for the up gradation of the lost dance form, the difference in their ideologies held them in opposition – which has affected the background of Bharatanatyam ever since. Rukmini Devi was a Brahmin who was married to an English Theosophist, George Arundale at the age of sixteen. She came in contact with the famous ballet dancer, Anna Pavlova who accepted her as a student. Pavlova later suggested Rukmini Devi to train in her ‘own dance from’. Following her advice, Rukmini Devi returned to Madras and trained under a traditional guru in the classical dance form, Bharatanatyam. She defied the orthodox custom that upper and middle class girls should not learn dance and set up Kalakshetra to train dancers from the upper and middle class families. The establishment of Kalakshetra played an important role in bringing Bharatanatyam from the temples to the concert stage. Balasaraswati on the other hand hailed from a family of devadasis. She was born in a lineage of women who were associated with the Tanjore music and dance since generations. Her mother and grandmother wanted her to become musician considering the social stigma linked to dance at that time but she decided to become a dancer against all odds. She gave her first performance, arangetram at the temple of Ammanakshi in Kanchipuram, marking the beginning of her legendary career. Rukmini Devi Rukmini Devi entered and Balasaraswati had carved their positions in the world of dance with a radically different perspectives. Rukmini Devi had a very clear goal of purifying the dance form. According to her, the dance form was precious but degraded because its reigns were in the hands of people with ‘ill repute’. She wanted to eradicate the stigma associated with it by passing it on to the hands of people from the upper or middle class. She thought that everything about Bharatnatyam needed to be purified so that it could regain its respectable position in the society. Also, she believed that the main reason for the degradation of this art form was the fact that sringara rasa (love) was the centre of the choreographies. The sringara rasa had led to the degeneration of the art form as introduced eroticism and sexuality in the art to the extent to make it vulgar. â€Å"To depict such things is unthinkable for me†, she said. She was not against the sringara rasa as such (she had performed love poems by jayadeva and kalidasa in her natya), but against the choreographies performed by the devadasi. The actions, mudras and movements included by them in their choreographies had become earthy from beautiful. She strived hard to replace the sringara rasa by bhakti rasa or ‘devotionalism’; devoid of any sexual referrant. Bhakti Rasa Rukmini Devi held Bharatnatyam as a national art form and worked towards its purification and propagating this art form in India and the rest of the world. She established the Kalakshetra – international school of performing arts, to fulfil her goals. Here, students from various upper and middle classes were trained in Bharatnataym and also some other dance forms. She also set up a theatre which gave a platform to her students and also to her innovations in the dance form. Thus, she made reforms to take Bharatnatyam to a whole new international level. Balasaraswati Balsaraswati on the other hand, was very proud of her mother, grandmother and her devadasi ancestors. She was very proud of the achievements of the devadasis in the world of Bharatnatyam. Unlike Devi, she fore grounded the South Indian nativity and stood by the Tamil roots associated with the dance form. She advocated preserving the tradition, and also keeping it in the hands of the  devadasi  community. Her argument was that the art would die if separated from the caste. She believed that Bharatnatyam was in its purest form and it required no modernization or reformation. At many occasions she reprobated efforts to purify the dance form saying. â€Å"Indeed the effort to purify bharatanatyam is like putting gloss on a burnished gold or painting a lotus†. This proves how high Balasaraswati’s respect and love for Bharatanatyam (in its existing form) was. She urged to adhere to the custom of Bharatnatyam being performed in temples and courts. She also urged taking Bharatnatyam on the concert stage. This gave a new dimension to the revival of the dance form. She also defended the maintenance of originality of the dance form, by supporting the long, solo performances being an important component of the dance form. She emphasized the importance of such elements in to context to maintain classicism, integrity and aestheticism of the dance form. She also believed that abiding by the Tanjore Quartet’s format was an important way of honouring the contributions of the court practitioners. Sringara Rasa Balasaraswati was particularly critical of the reformers who believed in transforming the sringara rasa of the form. She was quoted as saying, â€Å"Sringara is bhakti and bhakti is sringara†. She believed that there is an intricate relationship between the expression of love (sringara) and feeling of devotion (bhakti). She believed that sringara is the supreme emotion and that no other emotion could express so beautifully the mystic union of atma (soul) and the paramatma (The almighty). This rasa gives the dancer a wide scope of introducing artistic innovation from within herself. Balasarswati thus, believed that she was entrusted with the task of safeguarding the dance form by not allowing it to be modernized and easily accessible for corruption. In spite of all the discouragement faced from the world, she continued to protect the dance form, the purity and the originality of the dance form. A similarity in the differences In spite of all the difference and such radically opposite perspectives, both Rukmini Devi and Balasaraswati had the same agenda- of saving the dying dance form. They both strived in their own way to protect the dance form and to take it to a whole new level. Their efforts in bringing Bharatnatyam to the concert stage or proscenium against all the opposition and hurdles from the society are commendable. A choreographer should be thankful to the endeavours of these two torchbearers towards the revival of the Bharatnatyam. History was therefore selective. Rukmini Devi and Balasaraswati presented their understandings by emphasizing on some aspects and eschewing the others. How to cite Bharatnatyam, Papers

Static Timing Analysis free essay sample

With  designs becoming increasingly complex  by the day and transistor geometries shrinking, almost all the functional domains across SoC design teams are having a hard time to signoff their functions and Static Timing Analysis (STA) timing closure is also no exception. STA Timing closure is always an important and critical part of SoC design and lower technology nodes have only compounded the challenges for  STA teams. As the VLSI industry has entered  the epoch of a lower technology node,  diminishing transistor sizes and interconnect lengths have disturbed the ratio of cell and interconnect delays. This leads to requirement of signing off the SoC at multiple corners. After timing signoff at multiple Processes, Voltage, Temperature (PVT) corners, the silicon fabricated at submicron technology nodes shows appreciable increase in yield in terms of meeting timing specifications of the design. However, timing closure at multiple PVT corners is in itself a huge challenge for the physical design team. This article will discuss these challenges and touch upon methodologies available to overcome them. We will discuss in detail, our solution to reduce the number of optimization corners in order to achieve efficient and coherent timing closure in minimum time. But before this, let us discuss in brief, the need to have multiple PVT corners for timing signoff. Cell delays and interconnect delays are governed by manufacturing Process (P), operating Voltage (V) and ambient Temperature (T) properties of dies. These factors determine the physical properties of cells and interconnect like W/L ratio of cells and Resistance (R) and Capacitance (C) value of interconnects. At the 180-nm technology node and above, timing signoff at worst and best standard cell PVT corners with 2 RC extraction corners, namely, Cmax Rmin (Cmax)   , and Cmin Rmax ( Cmin) was sufficient. On similar lines at 90 nm node 2 additional process corners Best Hot (Best process, Voltage at max temperature) and Worst cold (Worst process, voltage at min temperature) were introduced for the robust timing signoff, specifically for hold timing signoff as hold is skew dependent . The RC corners for these 2 process corners were similarly Cmax at min temperature and Cmin at max temperature respectively. In 90-nm technology and above, a timing path is predominantly governed by cell delays. However below 90nm node, the contribution of interconnect delay in a timing path is significant and the Coupling Cap component (Cc) in net delay can significantly alter slack values at an endpoint of a timing path. In all we have 4 X 4 = 16 corners for a single Timing Mode/View. If we have 8 STA modes for a design, then in all we have 8 X16 = 128 runs for the design. The first solution to avoid such an enervating analysis for a single mode is to look for a corner that forms a superset of the reset of corners. However a graphical distribution of slack values for a design block across all the 16 corners shows that none of the 16 corners was a complete superset over the others, thereby leaving us with no other option but to signoff the design at 16 corners. A silver lining amid all challenges  listed above is that the situation is not that bad for setup timing analysis. Setup timing violations are primarily dependent on the delay of the timing path (cell delays and interconnect delays, combinational and sequential arcs). These delays are significantly different for cell PVT corners (worst corners have delays considerably greater than the best corners) . For setup timing where worst corners are a complete superset over the best corners, the choice is between worst cold and worst hot standard cell corners to find out most critical corner for setup analysis. Conventionally, worst hot corner has more delays but at lower technology nodes, worst cold can have more delays because the threshold voltage of MOS comes into picture and transistor gets slower at lower temperature due to temperature inversion phenomena). When it comes to RC extraction corners, cmin is never more critical than other 3 RC corners. So for multi mode multi corner optimization for setup we can select 2 worst corner cell corners and cmax RC extraction corner (xtalk corner also if necessary) for meeting most of the setup paths in the design. But the situation is completely different for Hold Timing. As hold is skew driven, it is very difficult to judge which combination of process cell corner and RC extraction corner out of the 16 combinations would have most of the hold violations in the design. As the slack distribution plots for hold violations show, none of the 16 combination is a superset over the other (4 plots have been shown here for convenience). The challenge is to find the optimum number of optimization corners so as to ensure that appreciable numbers of violations are fixed ithout compromising the memory and runtime requirements of timing and placement tool. This task becomes more daunting as extraction corners depend heavily on design layout. Even in the same design, different blocks are found to have different RC combinations that yield maximum violations, and so is the case across different designs. The graphs shown below represent slack distribution of? a design in   two different RC Corners while keeping cell corner common. Here each graph shows the slack at each endpoint for the corner combination specified in x and y axis. The frequency of blue dots both above and below the unity slope line indicates that some  endpoints are more critical for x axis corner while an equally considerable  number are more critical for y axis  corner. Thus no RC corner is superset over other RC corner. So our focus here is to find   a generic approach that help us in deciding few optimization corners out of all signoff corners such that by fixing timing violations in only these few corners   by   APR tool,   most of the timing violations are fixed in one go. Our methodology is to find the optimum number of corners for hold timing signoff and Multi Mode Multi Corner hold optimization. We took 2 design blocks and did a comprehensive hold analysis across all 16 corners individually. It isn’t necessary that selecting the top most critical corners for optimization would solve this issue but instead we can look for finding out corner that have the maximum common violations with   the other 15 corners . The magnitude of violations could be taken care by adding extra pessimism in the optimization runs through uncertainties. 1. For this we prepared a 16 X 16 matrix where an element of the matrix m (i,j) showed the number of common violations between ith  and   jth combination corner. . In the next step we considered one  best process corner, among the 8  (highlighted in blue color) having   most number of common violations with   each of the 8 worst process corners,   for example best xtalk (in blue)   has the   maximum number of common violations with each of   the 8 worst corners and similarly we considered one worst   process corner, among the 8 (highlighted in purple) having most number of common violations with each of the   8 best cases. As shown in the figure worst cold xtalk (in purple) has the maximum number of common violations with each of the 8 best corners. Please note that this case can be already covered under Step 2 listed above but in our case violations in worst process and best process violations were not correlating. In some designs one of best corner can have most common number of violations with worst corner and can be marked with different color code. Now for each row/column the corner with the maximum number of red,green and (blue/puple) elements would be out best choice for hold optimization. In our case, this gave us the hold optimization corners as â€Å"best xtalk† and â€Å"worst cold   xtalk†. After that we fixed hold violations in these two corners best xtalk and worst cold xtalk. Again a 16 X 16 matrix was made with the same rules as the first. Corners fixed : Best cmin and worst cold xtalk Again step 2 was followed and this time the worst corner with maximum common violations was found to best cmin. The first 2 set of fixes plus a third set of fixes on best cmin were sourced across all corners to give us extremely positive results. Corners fixed : Best cmin ,Worst_cold_xtalk, Best Xtalk Observation : The matrix formed after this third level of hold fixing showed us that on an average more than 98 % of each of the 16 corners ‘s original violations were found to be fixed. The only violations remaining were the uncommon or mutually exclusive violations. We were able to narrow down from 16 corners to 3 corners which can be a part of the MMMC hold optimization thereby reducing tool run time/memory requirement and also reducing the number of hold violations to a far extent. The exercise can be repeated further to improve the percentage of fixed hold violations. The same methodology can be extended across multiple STA modes also to find mode and corner combinations having most common violations among multiple modes and multiple corners.
