Think of the training data as a very tall and narrow table with 7130 rows and 78 columns. Note that it is sideways from machine learning point of view. That is the attributes (genes) are in rows, and observations (samples) are in columns. This is the standard format for microarray data, but to use with machine learning algorithms like WEKA, we will need to do matrix transpose (flip) the matrix to make files with genes in columns and samples in rows. We will do that in step 3B.6 of this assignment. Here is a small extract Gene Description Gene Accession Number 1 call 2 call ... GB DEF = GABAa receptor alpha-3 subunit A28102_at 151 A 263 P ... ...

To what extent can Lady Macbeth be seen as a female gothic protagonist at the start of the play Free Essays

At first meeting, Lady Macbeth appears to us as a ruthless predator, an emancipated woman driven by an all-consuming passion and displaying perfectly, the antithesis of womanhood. She has, it seems, acquired all the necessary requirements to fill the role of a female gothic protagonist. Whether or not she utilises these factors to the full extent and can really be called the protagonist will be discussed in further detail. We will write a custom essay sample on To what extent can Lady Macbeth be seen as a female gothic protagonist at the start of the play? or any similar topic only for you Order Now Her character is not unveiled until Act I Scene V where, with the use of three speeches, she exposes the workings of her mind and lay it out for the audience. Her second speech displays perfectly the idea of Lady Macbeth as a ruthless predator. She calls on the supernatural to ‘unsex me here, And fill me from the crown to the toe top-full Of direst cruelty!’ She asks them to ‘Stop up the access and passage to remorse’ and to ‘make thick’ her blood. Here she displays a woman incapable of any feelings of love or amity, but it is important to think of her before she makes this request. If it is necessary for her to ask for the remittal of her remorse, then she must have had the ability to feel such feelings beforehand. We are given no background information on this woman and it is therefore difficult to say if she was always like this or whether it was Macbeth’s letter that changed her; this appeal she makes is one of few insights into her p ossible mind-set as Lady Macbeth before the play. Her status as a woman who displays the antithesis of womanhood can hardly be doubted, but Lady Macbeth would not have publicised these feelings. We know this from her relation with Duncan who refers to her as ‘our honoured hostess.’ The King of Scotland would hardly encourage a woman to act the way Lady Macbeth does on the audience’s initial meeting with her. Indeed, Lady Macbeth is a woman changed entirely when in the presence of people of such high status. She appears to be a domesticated woman, one happy to be at home while her husband goes out to war to serve as a loyal citizen. And yet, we know otherwise. In her second speech, she refers to her home as ‘my battlements.’ This presumption of hers, this idea that she should own her home and not her husband would have been a farcical one. The most menacing speeches uttered by Lady Macbeth occur not just when she summons iniquity, but when she does so with a language that refutes and distorts her maternal nature. In her second speech, she speaks to these ‘spirits’ and asks that they ‘come to my woman’s breasts, And take my milk for gall†¦Ã¢â‚¬â„¢ This line turns this universally natural feature of womanhood into something dark and troubling. Adding to this, the suggestion of changing a mother’s milk, what she feeds her children on, to poison, is a disgusting one. Further on in the play, Shakespeare manipulates this perversion of motherhood again when Lady Macbeth conveys a fantasy of infanticide: ‘I would, while it was smiling in my face, Have pluck’d my nipple from his boneless gums, And dash’d the brains out†¦Ã¢â‚¬â„¢ This horrific image is so against the searing love a mother feels for her child, that it is impossible for the reader to accept that Lady Macbeth fully comprehends firstly, what she is saying and secondly, that maternal love despite her previous statement of ‘I know how tender ‘tis to love the babe that milks me†¦Ã¢â‚¬â„¢ However, Shakespeare has allowed the reader room for doubt. While we are certain that Lady Macbeth is a woman depraved of all the typical qualities of a homemaker, we do see a potential insight into the Macbeth’s sexual relations and Lady Macbeth’s ‘duty’ as a wife. Here, it appears she abides but it does become apparent that it is her who leads the way. Our insight into this idea is in her first speech where she talks of ‘pour[ing] my spirits in thine ear; And chastis[ing] with the valour of my tongue.’ The suggestion here that Lady Macbeth can impress things on her husband through the use of sex, would have been a shocking one. So while these sexual insinuations suggest the ‘wife’ side of Lady Macbeth, the knowledge that she can manipulate him as such, is once again the perfect display of the antithesis of womanhood. The gothic impact of Lady Macbeth’s indiscretion has less to do with her demonic entreaties, but rather more so with the reversals of her female nature, which show how willing she is to contemplate and fulfil her ambition for power. While certain aspects of her speech allow the reader to imagine her, for a second, as a woman happy to live and serve as a reclaimed wife, her ability to twist and distort words and ideas disallow the audience to hold these thoughts for long. This amalgamation of supernatural desires and her willingness to abandon her sex create, for the reader, a potent force of evil and the perfect female, gothic protagonist. disparagingly of her husband’s ‘human kindness’ but she summons demonic powers with her invocation: ‘Come, you spirits, / That tend on mortal thoughts, unsex me here, / And fill me from the crown to the toe top-full / Of direst cruelty’ (1.5.38-41). She continues in similar vein: ‘Come to my woman’s breasts, / And take my milk for gall’ (1.5.45-46). Her communing with the forces of darkness is expressed in terms that seek to remove the ‘compunctious visitings’ of her female nature. Later, in one of the play’s most disturbing images, Lady Macbeth expresses a fantasy of infanticide: I have given suck, and know How tender ‘tis to love the babe that milks me. I would, while it was smiling in my face, Have pluck’d my nipple from his boneless gums And dashed the brains out However, when it comes to her manipulation of Macbeth, she adopts the powerful weapon of sexual taunting: Art thou afeard To be the same in thine own act and valour As thou art in desire? When you durst do it, then you were a man. Lady Macbeth’s evil allows her at one and the same time to deny her maternal nature and to control her husband by invoking her sexuality. It is this capacity to distort her female identity to gain her political ends that makes Lady Macbeth at once a potent force for evil and a transgressive figure of the female gothic.

Work Policy and Procedure for Sustainability

Questions: 1) What impact did the previous generations use of industrialised agricultural practices have on this property? 2) What steps did Michael take to understand the issues and address them? 3) What do you think are the benefits of the program that Michael introduced? Answers: Q1:Land is used continuously and not given proper rest. Crops are not rotated in a way that replenishes the soil. Manure and chemical fertilizers are used to feed the soil, but through over-application these additives become a problem (Mineau Whiteside, 2013). Factory farms concentrate an unnatural number of animals in one place, which creates an unmanageable amount of waste. The creation and disposal of such enormous quantities of waste has a devastating effect on the air, water and soil surrounding factory farms (Nelson et al., 2014). Unlike human waste, livestock manure is not processed for sanitation. On factory farms it is commonly mixed with water and held in pits (called lagoons), and then spread or sprayed on cropland. Manure carries with it other substances that are used on industrial farms. These includeantibioticsand artificialgrowth hormones which contaminate waterways and affect the plants and animals that live in them (Conway Prett, 2013). Salt, a common component of manure from industrial dairies can damage soil quality and contributes to erosion (Ponisio et al., 2015). Factory farms emit harmful gases and particles such as methane and hydrogen sulfide, which can contribute to global warming and harm the health of those living or working nearby.Air pollutionoccurs due to the overuse of machinery, the mismanagement of manure, and the irresponsible feeding practices that characterize industrial farming (Zhao et al., 2013). Chemical fertilizers and pesticides have turned agriculture into a leading source ofwater pollutionin the United States. Runoff from factory farms kills fish, degrades aquatic habitats and threatens drinking water supplies. Additionally, factory farms use tremendous amounts of water, which cuts into our precious supplies of water that are not contaminated (Clay, 2013). Q2: Michael changed from conventional farming, that could stand on the top of the wind erosion. To stop the recharge from the area he started collecting water down the hill and use it for the growth, different types of seedlings are being planted to enhance the biodiversity. Other steps taken were: Ecological Footprint measures the amount of biologically productive land and water area an individual, a city, a country, a region, or all of humanity uses to produce the resources it consumes and to absorb the waste it generates with todays technology and resource management practices. This demand on the biosphere can be compared to biocapacity, a measure of the amount of biologically productive land and water available for human use. Biologically productive land includes areas such as cropland, forest, and fishing grounds, and excludes deserts, glaciers, and the open ocean (Herva Roca, 2013). Green Purchasing refers to the procurement of products and services that have a reduced effect on human health and the environment when compared with competing products or services that serve the same purpose (Dubey et al., 2013). This comparison can consider raw materials acquisition, production, manufacturing, packaging, distribution, reuse, operation, maintenance, and disposal of the product or service. Green purchasing is also known as environmentally preferred purchasing (EPP), environmentally responsible purchasing, green procurement, affirmative procurement, eco-procurement, and environmentally responsible purchasing (Ji et al., 2015). Life-cycle assessment(LCA, also known aslife-cycle analysis,ecobalance, andcradle-to-graveanalysis)[1]is a technique to assess environmental impacts associated with all the stages of a product's life from cradle to grave (i.e., from raw material extraction through materials processing, manufacture, distribution, use, repair and maintenance, and disposal or recycling (Kulak et al., 2013). Land use and management practices do not only have impacts on the land unit itself and the direct land users but also on close or distant neighbours and ecosystems. Impacts include effects on land productivity, on runoff, soil erosion and sedimentation, movements of nutrients and chemicals, contamination by wastes, atmospheric deposits through burning and wind blow, as well as wider effects of floods, drought, landslides and climate change (Buckley Carney, 2013). An improved approach must ensure: - development of policies which will result in the best use and sustainable management of land - improvement and strengthening of planning, management, monitoring and evaluation systems - strengthening of institutions and coordinating mechanisms - creation of mechanisms to facilitate the active involvement and participation of communities and people at local level (Morugn-Coronado et al., 2014, May). Q3: Planting sandalwood on his poor soils is stabilising a wind erosion ,water collected by Michael is used for the trees that are recharged away. By putting down 25 species of different types of seedlings and mix of local seedlings has made the wild life coming out and birds are again seen. He is achieving great growth rates for his bio diverse sandalwood plantation in a paddock that was not achieving a return from conventional agriculture. BENEFITS OF PROGRAMS: LCAs can help avoid a narrow outlook on environmental concerns by: Compiling an inventory of relevant energy and material inputs and environmental releases; Evaluating the potential impacts associated with identified inputs and releases; Interpreting the results to help make a more informed decision (Bessou et al., 2013). Green purchasing helps conserve natural resources, minimize pollution, reduce water and energy use, avoid environmental health hazards on our campus and within our community, divert material from the landfill (Grimmer Woolley, 2014).Improve the availability and use of environmentally preferable product, encourage Suppliers to reduce their environmental impact and to send that message up their supply chain, support locally produced goods and services, educate and inform ourselves, campus requestors and end users, and suppliers of the best environmentally responsible purchasing choices (Juwaheer et al., 2012).
