Aim of the Homogenisation Process

Aim of the Homogenisation extremityIntroductionEukaryotic cells such(prenominal) as liver-colored cells enclose a variety of unlike attributes of membrane bound structures c eithered organelles (nuclei, mitochondria) as well as macromolecules (ribosomes) (Padh, 1992).Subcellular divideation is an invaluable technique allowing scientists and researchers alike to successfully isolate and dissever limited subcellular components within the cell (Becker et al, 2009). This allows researchers to study the contrary organelles ( victimisation biochemical techniques) in a spaciouser degree of detail wherefore increasing our familiarity ab start the umteen distinct types of organelles and macromolecules, then leading to new scientific advances in this ever advancing era of lore and technology (Bonney, 1982 Berns, 1986).It is this real method which in the past allowed Christian de Duve to discover the lysosomes and peroxisomes for which he dual-lane a Nobel Prize with Albert C laude and George Palade in 1974 (Becker et al, 2009).Subcellular segmentation basis be safely divided under 3 major headings Homogenisation proceeded by cypheration and last-placely purification.HomogenisationThe aim of the homogenization crop is to effectively and efficiently disrupt and break the cells outer membrane thereby releasing their subcellular components (nuclei, mitochondria). This recess and breaking of the cells must be achieved in a manner that leave leave the delicate organelles of interest un rail atd and morphologically intact (Loewen, 2003).The cells to be homogenised ar kept in an isotonic buffer (0.25M sucrose, 1mM EDTA and 1mM of Tris at pH 7.0). This is to protect the fragile organelles from osmotic damage due(p) to osmotic unbalance as well as environmental instability such as pH interference (Guteriezze, 2010).Many antithetic homogenisation techniques hit up and are avai research lable, some such include mechanical grinding using Potter-Elveh jen water ice homogeniser, cutting methods using warren blender, ultrasonic vibrations in a suffice called sonication and utilising high pressure such as in the french Press (Loewen, 2003).The Potter-Elvehjen folderol homogenizer was utilize in this experimentation. The Potter-Elvehjen sugarcoat homogeniser consists of a polytetrafluoroethylene bray which is closely fitted into a glass homogeniser. The homogenising machine moves the Teflon pestle in a verticle up-down motion succession simultaneously rotating within the glass homogeniser containing the cells to be homogenised (Mangiapane, 2010).The space surrounded by the Teflon pestle and glass homogeniser is incredibly small (0.004-0.006). therefore as the Teflon pestle moves throught the glass homogeniser a fleece force is gene rated which causes flicker of the cells. The organelles which are released by this process pass undamaged, safetly through the gap between the pestle and glass homogeniser (Loewn, 2003 Mangipan e, 2010).The shear forces produced butt sometime be destructive to the organelles causing irreversible damage and therefore shear forces need to be controlled. This washstand be controlled by adjusting the gap width between the pestle and glass homogeniser. A big width undersurface protect organelles from damage but the negative position effect of this is that the generated shear forces impart non be strong bountiful to disrupt the cells and therefore few or none organelles will be stick in the homogenate. Therefore a careful balance between cell disruption and organelle damage must be of importtained.Chemical, animal(prenominal) and structural damage can be ca utilise to organelles due to shear forces which can cause errors when purifying the organelle using biochemical techniques due to enzymes proper(postnominal) to the particular organelle being damage or rendered inactive and these problems must therefore be castigate. Some such precautions which when utilised can overcome or minimise un required damage includes the use of different homogenisation techniques which are more sui gameboard for the cells being homogenised (osmotic disruption, chemical disruption may be considered). Carefull usage of the homogenising equipment (Lowen, 2003). sectionationOnce the homogenate has been make, it is ready to be placed in a cartridge remover and undergo centrifugation which will set off the different separates/organelles. Centrifugation generates a centrifugal force which separates the different types of organelles based on their size and density as well as the density and viscousity of the response the homogenate is in. Therefore the the high the molecular weight of the organelle the greater the exceed I will travel down the cartridge extractor vacuum tubes or the higher its depositionation rate and consequently the smaller the molecular weight of the organelle the smaller the distance it will travel down the centrifuge tube or the lower its sedimentation rate (Becker et al,2008 Mangipane, 2010). The greater an organelles sedimentation rate is the greater the organelles sedimentation coefficient (in Svedberg units, named after Theodor Sveber who developed the ultracentrifuge) will besides summation (Becker et al, 2009).Centrifugal forces can be reason usingFor example, if a homogenate containing nuclei, mitochondria and ribosomes is subjected to a centrifugal force, logically the nuclei will be near the bottom of the tube, the ribosomes at the top part of the tube and the mitochondria somewhere in between the nuclei and ribosomes.There are 2 main type of centrifugation methods contraryial centrifugation and density slope centrifugation.Differential centrifugationThis type of centrifugation plant life on the principles that large threatening molecules (nucei) will dedicate a higher sedimentation rate compared to small and less(prenominal) dense molecules (ribosomes) (Becker et al, 2009). During low centrifuge spee ds and short times the heavy and dense organelles sediment and can be collected, fleck as high centrifuge speeds and longer timer the lighter and less dense molecules will sediment and can in addition be collected (manipulative techniques).Therefore in the homogenate use in the experiment, by using appropriate centrifuge speeds and times the nuclei and mitochondria can be disjointed using 1500g for 10min and 20000g for 10min respectively.Density inc parameter centrifugationThe method utilize in density gradient centrifugation, also known as rate-zonal centrifugation works on the principle of separating molecules based on their densities and is achieved by using a density gradient in the centrifuge tube (manipulative techniques Becker et al, 2009). The density gradient is normally provided by a concentrated sucrose stem which increases in density towards the bottom of the centrifuge tube. The sample requiring fractionation is placed in a layer over the density gradient sucrose solution (Becker et al, 2009). As the centrigugation process proceeds, the different molecules or organelled of different densities are separated based on their densities and that of the increasing sucrose density. When the fractionation bands have been formed are are distinctive the fraction may be remover via a syringe or legal separation methods. This type of centrifugation can be used to tho separate mitochondria from lysosomes and peroxisomes since separately of them has a different density.Measurements of enzyme practise and macromolecular composition of fractions. purity of fractions.During the centrifugation processes, such as in the differential centrifugation the confused types of organelles and macromolecules form gelatinous shooters at the end of for each one consecutive centrifuge (Dyson, 1979). The different pellets produced contain a variety of different fractions of subcellular organelles and macromolecules and is non ad hoc for just a single type of organel le or macromolecule. As an example in the first centrifugation process to form the nuclei fraction at 1500g for 10mins, the nuclei is pelleted along with former(a) molecules of similar size and molecular weight such as unbroken cells, cell debris and pieces of the cell membranes (Bonney, 1982). In the bet on centrifugation to form the mitochondrial fraction at 20000g for 10min the pellet contains mitochondria, lysosomes and peroxisomes due to their similar sizes and molecular weight. In the final centrifugation process at 20000g for 10min a supported fraction was formed containing many small and low molecular weight molecules such as the endoplasmic reticulum, microsomes and ribosomes (Minorsky, 2009 Berns, 1986).As tell before fractions will not exactly require the organelles of interest but also other organelles and macromolecules. It is therefore necessary to be able to assess the purity of the fractions. This can be do in a variety of ways.Microscopic analysis via the light microscope or even electron microscope can be used to identify the different macromolecules present within the fraction, therefore giving an indicator whether or not the fractionation procedure has been successful. A mitochondrian therefore can be secern from a peroxisome or lysosome basen on its structure (Bonney, 1982). Microscopic anaylsis can also be used in assessing the biochemistry of the fraction by using different cytochemical techniques.Biochemical techniques are a really good way of assessing the type of organelle present as well as the purity of a fraction. Measuring enzyme performance is an excellet method sine some enzymes are very ad hoc and found in one particular organelle.Marker enzymes present in fractions and importance of the techniques involoved in the advancement of biochemistry and cell biology.Marker enzyems are routinely used in subcellular fractionation to differentiate between the many different types of organelles and macromolecules present within the cell. Mitochondria for example can be detect indirectly by the presence of succinate dehydrogenase while lysosomes can be observe by Acid Phosphatase (Bonner, 2007).The function of the mitochondria for example is to generate adenosine triphosphate (ATP) by a process called oxidative phosphorylation and an enzyme detail to the mitochondrion called succinate dehydrogenase can be used as a marker enzyme to differentiate between the presence of mitochondria and other organelles and macromolecules present in the fraction (Padh, 1992). Succinate dehydrogenase (SDH) is specific to the inner mitochondria membrane and is responsible for(p) for catalysing the oxidation reply of Succinate, which is a component of the citric acid cycle, into fumarate which is some other component of the citric acid cycle. Since flavin adenine dinucleotide (FAD) is reduced producing FADH2 (Guterize, 2010 Padh, 1992Girolamo, 2010).Succinate is the electron doner while FAD is the electron acceptor. The p roducts of the above answer are then reacted with an schmaltzy electron acceptor called INT(a tetrazolium salt) to form a red faded compound called formazan.This reaction is required because some(prenominal) the fumarate and FADH2 produced in reaction are colourless and therefore there is no certain way of determining succinate dehydrogenase natural action, therefore the loudness of the red coloured formazan produced during a specific timeframe in the second reaction can be measured using a spectrophotometer gives an indirect indication of succinate dehydrogenase application and therefore an indication of the presence of mitochondria as well as its purity within the fraction (guterize, 2010 padh, 1992).Electron microscopy of the isolated organelles is generally the final step in assessing the purity of the fractions as well as perusing their morphology (padh, 1992).It is these methods and techniques used in subcellular fractionation which has allowed researchers such as Geor ge Palade and Christian de Duve studying to understand and discover the structures, biochemistry and roles played by the various organelles.Resultsmesa 1 shows the slews of the homogenate, nuclei fraction, mitochondrial fraction and supernatant fraction. The Homogenate garishness was obtained after rat liver homogenisation NF volume was obtained after 2 consecutive centrifugations at 1500g for 10min MF volume was also obtained by 2 consecutive centrifugations at 20000g for 10min SF volume was obtained from the supernatant of the MF centrifugation. tabulate 2 shows known bills of bovine serum albumin (BSA) which underwent the biuret reaction the absorbances were measure using a spectrophotometer at 550nm. As protein amount increases so do the absorbances. This data was used to plot a BSA standard curve.Figure 1 illustrates the BSA standard curve which is a line of best fit. From this graph, the protein amount is determined by using the absorbance values for the different fraction shown in fudge 3 below. H, NF, MF and SF correspond to homogenate, nuclei fraction, mitochondrial fraction and supernatant fraction respectively. The vertical and horizontal red, blue, green and black coloured lines represent H, NF, MF and SF respectively.From the above graphical data Protein concentration (mg/ml), perfect protein amount (mg) and protein retrieval for each fraction coition to the homogenate can be calculated.HomogenateNuclei FractionMitochondrial Fractionsupernatant FractionFrom the above results the summate constituent of protein recovery relative to the homogenate can be determinedThe above calculated results are show together in add-in 3.Table 3 shows the absorbance values obtained from the spectrophotometer. form B shows the amount of protein that was determined from the BSA standard curve. Row C showed the amount of protein present in 1ml of each fraction the homogenate had the highest protein concentration, followed by the SF and MF and finally by the N F containing the lowest amount of protein concentration. Row D shows the total amount of protein in each of the fraction and therefore follows the equal pattern as the values for Row C. Row E shows the amount of protein regain relative to the homogenate The percentage of protein recovery was as follows SFMFNF.Table 4 shows the actual fraction concentrations used, obtained by diluting the original fractions (table 3) with phosphate buffer. The supernatant fraction was left undiluted.Table 5 shows absorbance of each of the fractions (0.2ml) which were diluted by the accompaniment of 4ml of ethyl acetate within formazan. The average absorbance minus the control gives the turn mean absorbance for each of the fractions. The control values for all 4 fractions were 0 because they were given as negative values by the spectrophotometer. The highest absorbance was recorded for the SF followed by the homogenate, MF and NF.By obtaining the data collected from the previously calculations in tables 1, 3 and 5 it is possible to calculate the total practise of Succinate Dehydrogenase (SDH), the percentage recovery of SDH relative to the homogenate, the specific action mechanism of SDH and the relative specific performance of SDH relative to the homogenate in all 4 fractions (H, NF, MF and SF).Below are the equations which will be used in the calculationsBeer-Lamberts Law The calculations below will make (concentration) the subject of the formula as well as prove that the units for = or . this can be rearranged to form,, since always equals to , the equation can now be represented as,, the units of this new formula can be calculated as follows,the in the bottom fraction can be cancelled out with the at the top giving,Which gives which is Molarity or concentration.The equation will be used throughout the rest of the calculations. The Formazan molar extinction coefficient= and the assay volume used will be 0.004L (4ml).HomogenateThe absorbance for the homogenate in table 5 was 1.1385 therefore, since this can be arranged to give,The volume used was which gives therefore, legal action total natural process of in -1The answer is required in sinceTherefore total activity for Homogenate =Therefore specific activity for HomogenateNuclei Fraction (NF)The absorbance for the nuclei fraction in table 5 was 0.117 therefore, since this can be arranged to give,This gives,Activity total activity of inThe answer is required in sinceTherefore total activity for Nuclei Fraction =Therefore specific activity for Nuclei FractionMitochondrial Fraction (MF)The absorbance for the mitochondrial fraction in table 5 was 0.398 therefore, since this can be arranged to give,This gives,Activity total activity in in The answer is required in sinceTherefore total activity for Mitochondrial Fraction =Therefore specific activity for Mitochondrial FractionSupernatant Fraction (SF)The absorbance for the supernatant fraction in table 5 was 1.485 therefore, since this can be arr anged to give,This gives,Activity total activity in inThe answer is required in sinceTherefore total activity for Supernatant Fraction =Therefore specific activity Supernatant FractionCalculations for the % SDH recovery and specific SDH activity relative to the homogenateSince the % SDH recovery and specific SDH activity is to be calculated relative to the homogenate, therefore the homogenate percentage for them both will be 100%Nuclei FractionMitochondrial FractionSupernatant FractionThe main findings of these calculations can be summarized in the table belowTable 6 shows that SDH activity is highest in the SF, followed by the homogenate, MF and finally by NF. The %of SDH recovery (relative to the homogenate) was greatest in the SF, followed by the MF and the NF. The specific SDH activity was greatest in the SF followed by the MF, NF and lastly by the homogenate. The % of specific SDH activity (relative to the homogenate) was greatest in the SF, followed by the MF and NF.Figure 2 illustrates the main findings from table 6. It can be seen that % SDH recovery increases from the Nuclei fraction to the supernatant fraction. The % of specific SDH activity steadily falls from the supernatant fraction to the nuclei fraction.Discussion concord to the results obtained in table 3, it was seen that 99.25% of the protein relative to the homogenate was still present within all the fractions. This high percentage recovery indicates that very little protein was lost during the formations of the nuclei, mitochondrial and supernatant fractions by centrifugation. The 0.75% of protein that was lost is most likely to have been lost while homogenizing the pellets formed during each consecutive centrifugation process. During the usage of hand homogenizers small quantities of the pellet containing the proteins are stuck to the homogenizing vessel or the pestle. These small quantities of proteins being lost during each hand homogenizing process therefore contributes to the loss of proteins recovery. From this high protein recovery it can be said that the overall homogenisation process was very efficient.During each successive centrifugation at different speeds a distinct pellet was formed, thus indicating the separation of organelles. In table 3, different amounts of proteins were present within the pellets. Since these proteins are associated with the different organelles present, this indicates that since different amounts of proteins were found in the fractions therefore various different types of organelles must also be present. however this is not always the sequel since proteins from other fractions could have been damaged due to the homogenization and centrifugation processes. Therefore the calculations performed on Succinate Dehydrogenase activity, recovery and specificity (table 6, figure 2) showed that that the total SDH activity was highest in the supernatant fraction. Since SDH is a specific marker enzyme to the mitochondrion organelle as expla ined earlier, the data suggests that the separation of mitochondria during centrifugation to be present within the suspected mitochondrial dfraction was not optimal. The supernatant also had a very high protein content of 885mg (table3) which indicated therefore that most of the organelles have separated into this freaction, thus indicating the hight amount of SDH activity within the supernatant fraction.In a differential centrifugation process the successive increases in the centrifugal forces employ should create a gradient of the presence of different organelles, with the heaviest molecules in the centrifuge tubes with lowed centrifugal forces, the mediam molecular weighted organelles such as mitochondria in a centriguge in the centrifuge with a medium centrifugal force is use and small molecular weight organelles such as ribosomes in the centrigue tubes where the highest centrifugal forces are applies.Therefore the separation of organelles has occurred but not to a great extent as seen by the reults in table 3 and table 6. Seperation of organelles could have been greatly improved by possibly refining the lab protocol. To ahieve better mitochondrial separation and therefore more accurate SDH activity measurments the centrifugation process should be done at 20000g but for 20min and not 10min as stated by Loewen (2003) and Becker et al (2009). This will help separate the mitochondria out better.Different centrifugation methods such as density gradient centrifugation can be utilise after the intital differential centrifugation to better separate organelles of similar sizes such as mitochondria, lysosomes and peroxisomes. The new fractions produced can by the densiy gradient centrifugation can be recovered with the use of a syringe. Many other techniques such as the initail homogenisation stage could also have been changed and other techniques could have been used as described earlier.ConclusionIt was found by this experiment that subcellular fractionation is not a perfect method and therefore inaccuracies must be expected. But it is a process that has revolutionaised our understanding of cell structure and function.It was found in the experiment that differential centrifugation can separate organelles to an extent to form a nucleic fraction, mitochondrial fraction and supernatant fraction. Marker enzymes which are present in specific organelles can be used to help distinguish between different organelles as well as the fractions relative purity. SDH was used in this experiment and was found to be present higher in the supernatant, possibly due to experimental error. SDH was specific to the supernatant fraction therore again indicating the presence of mitochondria in the supernatant.The usage of such techniques in this ever advancing era of science and technology has set the stage for future studies and techniques involved in further studying the cells and increasing our knowledge of life as each mean solar day passes.

All About My Mother, 1999 | Analysis

any around My Mformer(a), 1999 compendiumThis is essay will attempt to examine the photograph both About My Mformer(a) using different interpretations and theories about gender roles in connection to create a view of Almadovars work. I shall explore Almadovars work in terms of his difficulty to interpret effeminate identification and how he uses kindly inter secondions as a short cut to portraying women and men as one. The movie was released in 1999 at a time when homosexuality was silent politically oppressed especially in proportion to gay marriage. Almadovar uses his video to show a more politically accepted view towards homosexuality between both men and women in a radical way of life than at the time of release were accepted. As Stephen Maddison suggests Almadovar is believed and been labelled as a Womens director in as much as he, as salutary as others (typically Tennessee Williams), signify a standard for the identification of women and/or homosexuality.All A bout My Mother, predominately uses barbs from Tennessee Williams tamper A Streetcar Named Desire and it can outright be seen that this is a benchmark for Almadovars concerns in relation to the characters and their backgrounds, especially that of the injects fe staminate protagonist, mankinduela. We also repeatedly see the uniform scene from Streetcar which is never the less done on purpose. The scene is that of the end of the play where Stella supposedly leaves her husband, Stanley. The director obviously wanted us to see this scene for what it was as he shows this scene in relation to women and their strength. The particular that this scene is shown repeatedly throughout the film (Manuela and her son watch it together and we see the scene and again after he dies) shows us how varied productions of the same play direct changed Williams ending, most notably from the original where Stella is left sobbing on a step while Stanley kneels beside her and puts his hand across her bl ouse in that locationfore re demeanor his control over her. In Almadovars film however, Stella leaves stage right unspoiled after calling Stanley a bastard. In Almadovars case, he is trying to show how heterosexuality seems insufferable today as it appeared in Williams play. It also denotes that women have choices in life and are not controlled by men.As Mulvey suggests in Performance analysis with the relation of women to men women are simultaneously looked at and displayed, with their appearance coded for strong visual and titillating impact so that they can be said to connote to-be-looked-at-ness. All about my mother seems to take this surmise and turn it on its head and throughout the entire film there seems to be this allure towards creating a performance that is different from the way courtly performances are held. Mulvey goes on to explain that Budd Boetticher saysWhat counts is what the heroine provokes, or quite an what she represents. She is the one, or rather the l ove or fear she inspires in the hero, or else the concern feels for her, who makes him act the way he does. In herself the women has not the slightest importance.Almadovar uses this as a agent to show the opposite of such belief. It becomes quite clear that in All about my mother the focus is concentrated on the relationships that Manuela holds and creates with the other women in the film. She is the heroine the main objective of the film is for Manuela to aim Estabans father which takes the central put at the start but this is pushed aside quite quickly and the film becomes Manuelas journey through the past. Finding Estabans father resurfaces later on in the film but does not arrange the narrative. Of course theorists including Mulvey suggest that Man is the bearer of the look of the spectator whereas Almadovar shows us in Mother it is the women that controls the look. The focal point of the film if on Women.Almadovars film makes obvious note and eccentric to the film All abou t Eve (1950). The actress in the film Margo seems to contradict the idea that she could be seen as just a consistency and a voice but at the same time we are interpreted through the story by a man watching from a nearby stall. The man is still the bearer of the look and with this in understanding we are in some ways forced to side with the staminate protagonist in the piece.In Mother, we can see that Manuela does not equivalence with Mulveys views on the act of the female in cinema. While Mulvey suggests that women are looked at for erotic pleasure which in direct correlation to the leitmotif of erotic spectacle from pin ups to strip-tease, Manuela becomes a mother, not only to her son but to the other women in the film and shows professional mothering skills. We essential not forget that in the film she displays her skill for cooking and nursing and she is also an actress whom can improvise and lie convincingly. Predominantly the film is about mothering. And this is seen thr oughout the film and coincidently the film lacks all fathering. The only father in the film is that of sis Rosas father whom suffering from Alzheimers has become child like, dependant on a women.The consensus that is the men that are the heroes of the film and also the bearer of the look does find its way back into the picture by the end of the film. It is Esteban the second who creates the miracle at the end of the film, when his HIV passed on by sister Rosa, is neutralized. However we must realise that this comes from a child dependant on the other the women in the film and that his HIV miracle is from the utopian of his gender dissident mothers.A observe character in this film which we can interpret in some(prenominal) different ways and use to look at Almodovars work as a whole is that of Agrado. She is the lead transvestite character in the film and still bears the male hood of a penis. Almodovar uses Agrado to go against the convention of traditionalistic cinema. Like so many other lead transvestites in film Agrado does not seek camouflage or the suppression of herself. She does not profess to be anything else but what she is and this is how she gains her affirmation. The topic of Transgender is one which falls under fierce debate and with relation to drag has its place in films. Topics about the body and gender in relation to transgender and drag will help us to reconsider such concepts which, in this film, are overlaid throughout the whole film. Transgender is. as expected, one factor that has led to a reconstruction of views and theories in relation to gender. As butler says in Gender Trouble Feminism and the putrefaction of identify (1990) imitating gender, a drag queen reveals the imitative structure of gender as well as its contingency. It is hard to pick up on or read Almodovars transgender characters especially in relation to Agrado. Butler goes on to cite that of Esther Newton where Newton describes the drag as a doubly inversion where by the appearance is an illusion. The external appearance is feminine to the shopping center but the interior is very much masculine but the same can be said vice versa. With this is mind we cannot take Agrado as either a man or a women in fact her position between the two provides the dramatic escape from the male heed that is intended. Agrado, however, still portrays the characteristics of a man especially with her speech when the play is cancelled. She is brassy with her body and explains that her authenticity comes from the production of herself that she has created. Even though Agrado is not your conventional drag cabaret esque, she is a type of gender parody as Butler explains. Agrado becomes this parody of the original that of the normal gender identification. Butler explains that it is a production which, in effect that is, in its effect postures as an imitation. Agrado is nevertheless an imitation of a women and an imitation of a man. We somewhat feel sided with Agra do though with her openness and he disregard for peoples approval. Although this is somewhat because of the comical portrayal presumption by the actor. However, even though Agrado is somewhat a parody and an imitation, Butler argues still that maybe all gender is just an act. in other ritual social dramas, the action of gender requires a performance that is repeated. which leads her on to This repetition is at once a re-enactment and re-experiencing of a dictated of meanings already socially established. With this in mind we can take Agrados image in the film as one for both men and women. The male still receives some of the male gaze as it were but it is mimicked by the act of the drag.

The Online Advertising Overview Media Essay

The Online Advertising Overview Media EssayAs the presence of technology meshes into either aspect of our lives, vigorous advert has been recognized by many if non entirely marketers as being the future, but is it truly? Mobile devices lease vexn over our lives in many aspects. With their ability to shoot video, take pictures, playing your music library, browse the net income and so on these raw(a) features stick come forward marketers to target consumers via wandering(a) ads and vigorous applications. As time passes and technology evolves, new types of advertising venues spring up transitioning from newspapers to billboards, TV and radio, and straight the internet. The authors of a peered reviewed critical article discuss how, Online advertising has three characteristics ease of targeting alter contents and inter exertion (Dhar, Subhankar, and Upkar Varshney, 356). In comparison to TV or radio advertising, the internet medium allows advertisers to create interacti ve advertisements that discount be tailored to be individualize and target the consumers direct pleases. But with the introduction of new methods and technologies to the market, it does non come without its disadvantages.Online Advertising OverviewThe end of the 20th century and the beginning of twenty-first were characterized by rapid developments of communicating weapons. Advertising delivered over the Internet or better known as online advertising has nonplus a large source of tax income for web- ground businesses. Internet- found advertising is a gale of creative destruction (in the speech of Schumpeter, 1942) sweepin g across the advertising and media landscape. Online advertisings humble beginnings began in in 1994 when HotWired, a web magazine, sold a banner ad to ATT and displayed the ad on its webpage (Kaye and Medoff, 2001). But since that time, the e-commerce hype has taken hold, and the focus has already moved on to the officious Internet. The new technology ch anged the world by revolutionizing communication at a time when mobile computing technology as a communication tool was solely limited to telephone. However, due to digitalization and the integration of telecommunication networks and Internet technology, mobile devices name evolved to provide the same realize as full-scale Internet-enabled computers. The convergence of these technologies provides endless possibilities for mobile computing applications and usage. M-advertising is tatty and back tooth be highly targeted towards a certain individual. The strength of mobile devices as direct marketing tools has not gone ignored and advertisers view realized the opportunity to use the mobile channel to school text randomness to targeted consumers. Unlike traditional print, TV, or even email advertising, companies can now acquire specic consumer groups or even individuals, virtually anywhere, anytime, and based on the physical location of the mobile user. In addition, companies cook much association about their client pool than ever before. This provides businesses with the opportunity to reach their prospects when and where it is just about appropriate for the effectiveness of a marketing campaign. M-advertising could some belike become a very powerful new marketing tool enabling businesses to customize and personalize advertising for mobile users.The Negative Side effects of Mobile AdvertisingAlthough at that place are various denitions for the concept of M-advertising, no usually accepted denition exists. This is because not much research is done in the area of M-advertising. In the present article M-advertising is referred to as the sending of electronic advertisements (mobile ads) to consumers tolerateing mobile devices. M-advertising is regarded by many as one of the most lustrous and protable business opportunities amongst mobile computing applications. A recent mobile marketing survey suggests that about 7% of the mobile users would be testamenting to receive mobile ads if they were relevant. Unlike personal computers (PCs), mobile devices typically are not shared, which allows for precise targeting of advertising to a single person. Moreover, mobile users rarely leave their house without their device and use them frequently throughout the day. As a result a message sent to a mobile device commands the immediate attention of the mobile user and whitethorn be perceived as intrusive if the message is unanticipated.Mobile advertising is inexpensive and novel, and can be highly targeted towards a certain individual. The potential of mobile devices as direct marketing tools has not gone unnoticed and advertisers have realized the opportunity to use the mobile channel to text cultivation to targeted consumers. Unlike traditional print, TV, or even email advertising, companies can now reach specic consumer groups or even individuals, virtually anywhere, anytime, and based on the physical location of the mobile user. In addition, companies have more than knowledge about their client pool than ever before. This provides businesses with the opportunity to reach their prospects when and where it is most appropriate for the effectiveness of a marketing campaign. M-advertising could most likely become a very powerful new marketing tool enabling businesses to customize and personalize advertising for mobile users.The authors bring up the negative side effects of mobile advertising which include junk e-mail mail, SMS text messages, and cover invasion. The authors go on to condone that, Since mobile communication is perceived as a truly private way of intercommunication, consumers can easily have a feeling that their privacy is invaded (Dhar, 356). The biggest fears that have arisen in recent years are location based marketing via GPS enabled mobile devices. (Dhar, 356). It isnt a surprise though that the idea of combining location information and user data could raise a serious privacy concerns for consumers because the activity of the individual can possibly be traced, which the authors also bring up. concealment of the consumer can come in many different tolerance levels.Consumers straightaway prefer advertisements which are geared more towards their interests than ones that dont. Email and some other types of internet messaging services are often times the center of email targeting. A scholarly article by Evelyne Beatrix Cleff affirms that, Unanticipated advertising messages, commonly referred to mobile spam, are considered to be a form of privacy misdemeanor (Cleff, 229). Data which is peaceful from the market is used to create a indite of the consumer and help to categorize what that persons interests are. Cleff later states in the article that These practices may go across to an over-collecting of personal data without the proper implementation of personal data privacy, much(prenominal) as providing a set of standards governing the collection as hearty as the u se of personal data and addressing issues of privacy and accuracy (Cleff, 229). Since most of use our smartphones for popular complaisant networks such as Facebook, Twitter or Instagram, our standard of privacy as changed completely. 50 years ago, for example, the general spate would have never dreamed of putting up their personal home phone number up on a billboard for all to see. Yet nowadays, Facebook users will post even their home addresses on their profiles and other social networking websites with millions of eyes to see it.Because these advertising methods interfere into peoples private information, there are opt-out programs when using these services that restrict personalized advertising from company any information from your online browsing habits. A statement made by Cleff brings up the point that Consequently, privacy fears may not only be limiting the growth of m-advertising, but may also be affect the validity and completeness of customer databases and proles, le ading to inaccurate targeting, wasted effort, etc (Cleff, 229). Because online privacy has been a huge issue, there has been doubt that as the consumer becomes more slopped by the presence of advertisements on the internet. Since literally all major social networking and online e-tailors provide opt-out programs for their users, will it be able to provide continued revenue growth in the coming years? pattern and The FutureRegulation in the United States falls under the federal Trade Comission (FTC) with their Federal Trade Commission Act (FTCA) which protects consumers from unfair practices by sellers and marketers alike. A scholarly article in the Texas Law Review by David DeMarco goes indepth on the subject field of privacy issues related to online marketing methods and subsequent regulations that comes with it. He goes on to explain that Although e-companies and Internet users may differ about the degree of access to collected information that companies ought to provide to the ir customers for verification purposes businesses have a compelling interest in maintaining accurate and complete information about their customers (DeMarco, 1042). He goes on later to explain how there has been a push in the finishing two decades to push for industry self-regulation which is considered by a source in his article to be an abject failure. Because the internet is so vast and unregulated by governments, there have been huge doubts as to how consumers privacy will ever be regulated. According to a statement made by DeMarco, At the core of the self-regulatory regime sits a websites privacy policy (DeMarco, 1045). Since websites drug abuse take responsibility for your information, who will? People dont realize as they allow for these websites and applications to access our photos, contacts, emails and so on, we give up ourselves to potential criminals that may frig around on the internet. As social networks come and go, the privacy we give up wont change. Society today as shifted completely due to the internet and without regulation, privacy or the idea of it will become nothing more than a word since all our information will be out there for the taking, regardless of your opinion.Overall, privacy issues and mobile advertising have cancelled into something highly taboo. Opinions on the matter vary from consumer to consumer due to younger people being more open about information their parents generation would have deemed unimaginable to post on the internet for all eyes to see. Laws and regulations by governments cannot keep up with the ever changing fads on the internet. From location based personalized advertising to the billboard you drive past on highway, mobile advertising is becoming embedded into every aspect of our lives. Consumers today carry their phones everywhere and with the mobile internet service providing the link, millions if not billions of people have their information gathered daily to provide a more personalized and creepy ta rgeting campaign for your buying desires.

Exploring the importance of communication in nursing

Exploring the importance of conference in breast feedingThis essay leave alone explore the importance of chat in nursing define converse and look at the different modes of chat and barriers to parley. A reflective model allow for be employ to tell how communication impacted on c ar deli actually in practice. Although distributively soulfulness will bring their own experience of directions to propound, it will discuss how student treats buttocks develop their skills that will assist them to earthly concernipulate tenuous communication and as well how qualified nurtures continue to scam communication through examine up their profession.Baillie, (2009) indicate that It is predominantly imperative for a deem to bewilder and develop powerful communication skills. A nurse will ready contact with a wide range of individuals during nursing this involves the forbearing and their relatives and also members of the health care police squad. (Thompson 2003, cited in Baillie 2009) suggests that communication is non only needed whilst transferring knowledge from one person to another, it plays a signifi pilet role in relationships.Kenworthy et al. (2002) indicates that parley comprises of trey fundamental cyphers the sender, the receiver and the mental object. Successful communication can be defined when the receiver is adapted to interpret the senders message whilst reflecting on their thoughts and feelings and the message received is almost accurate to that of the sender. There are various modes of communication that a nurse whitethorn use. For congresswoman, face to face contact, telephone calls, emails and letters. (Kenworthy et al. 2002)Daniels et al. (2010) explicate that communication has two parts a literal and a non literal message. Verbal communication is associated with legal transfer and usually heard through the persons ears, hitherto paraverbal cues for example, pitch, speech, inflection and volume can be associated w ith verbal messages changing the intelligence meaning. Different cultures whitethorn find spoken language to be toughened to understand be build paraverbal cues whitethorn differ from one culture to another. However, paraverbal cues such as a happy friendly smile or crying with heartache are associated with different cultures and may help with a ethnical barrier. (Daniels et al. 2010) The commission in which a nurse talks and the tone of voice can be very quieten to a patient, however a patient can also misinterpret the tone as being demeaning or they may even become frightened. Another very important factor suggested by time out and Bailey (2008) is the way in which a nurse may choose words ensuring that a patient will understand and not be confused with any aesculapian jargon.A nurse requires excellent awareness of communication theories whilst giving verbal expire overs in both hospital and community settings. A report will only become effective during handover if the n urse has a confident attitude, along with good verbal and non verbal skills cr take in an ideal environment for communication between the healthcare team to examine continuity of care.(Thurgood no date )Nurses are responsible for maintaining confidentiality. (NMC, 2008) Confidentiality is imperative in a alterative relationship with in goation only being shared between take away people. (Sundeen et al. 1998)Nonverbal communication is made up of all types of communication, with the exception of get along verbal communication. Nonverbal communication is usually observed through the shopping center however, other senses in the body can compliment this. (Kenworthy, 2002) Nonverbal aspects of a message can accept kinesis, facial expression, gesture, touch, movement, body language and eye contact. (Baillie, 2009) Nonverbal communication can be divided in three ways sign, action and object. Sign nonverbal communication can hold hand gestures and sign language, action nonverbal commu nication can include how you move around, involving body movements that do not offer precise signals. physical object nonverbal communication can include furnishings, hairstyles and clothing. (Sundeen et al. 1998)Written communication is for sure a significant method of communication and is crucial in a healthcare setting. The (NMC, 2008) states that it is imperative that all records are kept clear and accurate. This essential include all information on assessments, discussions, treatment and the effect of them. Unfortunately, (Bailie, 2009) points out that written communication is an area that is a lot ignored, stating that good written communication is vital to protect the patients welfare, encouraging high standards of continuity and clinical care, ensuring healthcare team members receive accurate information.Bailie, (2009) suggests that there are different barriers that may prevent a nurse from communicating that may influence the development of a therapeutic relationship, a rguing that Physical barriers may possibly include the surrounding environment, a patient who is in need of pain circumspection or any speech, hearing or visual problems. Bailie, (2009) indicates that psychological barriers may include the emotional needs such as anxiety or personality issues such as a person being retract or having different beliefs and social barriers can be caused if a person feels that their own social status is categorised by hierarchy, religious or culture beliefs.Students are promote to keep reflective journals of experiences whilst on clinical placements. Reflective journals change students to learn from their experiences, enhancing their communication development. However, education should be a lifelong experience in that qualified nurses are also encouraged to keep journals. Journals are known as reflective practice and studies grant shown that using these can lead to better practice. (Sully Dallas, 2005)I now devise to use Gibbs model of reflection (1988). This model of reflection is simple to line for a send-off piece of reflective write (please see concomitant 1). The patient who has been used in this scenario will be referred to as Mr Jones. The causal agency for not using the patients real name is to respect the patients confidentiality. (NMC, 2008)On my mo day of placement Mr Jones was transferred to the ward from the Accident and Emergency Department. During handover the nurse explained that Mr Jones had been referred from his world-wide practitioner since he was complaining of pain in the throat area. As anteriorly mentioned, Thurgood, no date states that a handover will only be successful if the nurse has good verbal and non verbal skills. Mr Jones general practitioner was also concerned as he had not eaten anything and drank very little over the previous two days. Past health check history revealed that Mr Jones had been diagnosed with give tongue to and throat crabmeat three months ago and was currently r eceiving chemotherapy treatment at another hospital. However, the nurse described that Mr Jones had become quite angry at times and that he removed his venflon out of his arm and refused fluids.My instruct asked if I would assist her whilst pickings Mr Jones observations. The observations snarled pickings the patients temperature, pulse, respiration and blood pressure. Comparisons were then compared to the patient baseline and plotted on a graph. Baillie, (2009) suggests that all nurses who observe patients should deport the infallible skills and knowledge to understand the measurements and take appropriate action.The medical team trenchant that the way forward with medical treatment was by firstly ensuring that commensurate fluids were given to Mr Jones. The doctor asked Mr Jones for consent to insert a venflon in his hand whilst explaining the importance of fluids in the body, yet he kept shaking his head. The (NMC, 2008) states that we moldiness(prenominal) gain consent to begin with any treatment and respect the patients choice. The doctors trenchant that they would prescribe Mr Jones a supplement make whoopie. ( cancerhelp) suggests that Supplement drinks can be used if a patient has a poor appetite and not competent to take in enough nourishment into the body. The medical team discrete that the nurses on the ward should encourage Mr Jones with oral fluids over the following twenty four hours and assess from there. Mr Jones became quite angry with the doctors and started pushing his arms away, actuate them to leave.Once the medical team had left I volunteered to rag floor with Mr Jones as he appeared to be quite bother. I introduced myself as a student nurse. Mr Jones seemed a very pleasant man however, I shortly realised that Mr Jones found it very knotty responding to my questions due to his speech. Mr Jones became more than upset and at this point he started to cry, I reached out for a interweave and passed it to Mr Jones, I also held his hand to comfort him. As mentioned previously, Bailie, (2009) suggests that non verbal communication such as touch can be reassuring to the patient. I mat up quite nervous at this point, being a student and not experienced, I was not sure what to talk about next, so I stood up and told Mr Jones that I would be back in a minute. I walked to the toilet and became upset, I mat absolutely useless not knowing what to do and more so, to see a grown man similar to my own dads age crying. I barf a abject list of cold water over my face and wiped my eyes before I went back on the ward to prevent people from comprehend that I had been upset.I spoke to my mentor and discussed with her that I thought Mr Jones was struggle to communicate with me as his speech was very poor and how upset he had become. (Maguire 1978, cited in Hanson 1994) states that a patient with cancer may find it difficult to communicate to show any worries that they might piss. My mentor explained to me tha t speech more often does become deteriorated when people have mouth or throat types of cancer. I asked my mentor how she matt-up if I offered Mr Jones a pen and citepad to enable him to write things floor or if that at any time he tangle he could not communicate by speech comfortably. Baillie, (2009) indicates that speech problems can cause a physical barrier to a patient. My mentor said that she thought it was a good idea and that I could drive if I wanted to.I returned to the bay and found that Mr Jones had pulled the curtains around his bed. I can understand that Mr Jones wanted privacy from the other patients and maybe supply as he was clearly upset. I popped my head around the curtain, smiled at Mr Jones and asked if he was happy for me to come and sit ingest with him. Mr Jones smiled and started tapping on the chair, gesturing for me to sit down. I sat down and asked Mr Jones if he found it difficult to communicate with his speech and he nodded. Speech disorder, (2009) s uggests that Cancer of the throat can cause loss of the individuals voice and speaking ability. This can be problematic for a patient who would normally use verbal communication. I then move to show Mr Jones that I had brought a note pad and pen, offering for him to use if he wanted. Mr Jones smiled at me and wrote down thank you. Mr Jones then started to able up, writing down that he felt secluded and on times felt patronised by the doctors because he used to live in Pakistan. I reassured Mr Jones and asked why he did he feel this way, he replied by saying that he was confused, there with things he did not understand, the doctors do not harken, he was very scared of dying and asked me if he going to die. Corner Bailey (2008) indicate that doctors prefer to use closed questions as opposed to open questions, concentrating on the biomedical model and not the emotional needs of the patient. I explained to Mr Jones that I would ask a member of the team to come along and have a chat with him and try to answer the questions that I felt I could not answer being a student nurse. At this point I asked Mr Jones if he would like to have a drink of water and he gave me the thumbs up. I felt really good with myself at this point, I was not experienced however, I had encouraged the patient to drink a small amount of water.I then discussed this with my mentor who agree that this patient absolutely needed to be able to understand what the medical team were explaining to him and equally important that the medical team must listen to the needs of the patient. Corner and Bailey (2008) argue that it is important for a patient to have a balanced relationship, along with good doctor-patient communication to enable a patient to have faith in their professional opinion. My mentor asked me to be present with her, whilst she had a chat with Mr Jones and I agreed. My mentor came down to the patients take aim to ensure good eye contact and allowing the patient to answer some open questions, to enable us to get a good sense of how he was feeling. Wiggens (2006) suggests that open questions will gain an enhanced assessment of the patient, allowing them to speak freely. Mr Jones felt frequently more at ease once my mentor had finished explaining the importance of fluid and nutritional intake that the body needs. Mr Jones was able to write down on the notepad any questions that he felt had been unanswered and anything that he wished to have a better understanding of. Gurrero, (1998) suggest that nurses must be willing to use other means of communication aids, for example white boards, writing pads and pens.The hospital had kept a food chart for Mr Jones since he had been admitted into hospital, clearly showing a very minimal amount of fluid intake and no nutritional intake. My mentor decided to show this to Mr Jones, fortunately he mum and consented to have a new venflon put back in his arm. Mr Jones continued to write down that he felt he was unable to swal low properly and that he would prefer to have fluids this way. My mentor phoned the doctor to come to the ward and Mr Jones happily consented.I felt totally powerless when seeing the frustration that Mr Jones showed towards the medical team during his first assessment on the ward. I could see that there was nothing that the medical team could do to encourage Mr Jones to have the venflon put back in. I believe that because of the breakdown in communication from the doctor, Mr Jones became very distressed. As previously mentioned Corner and Bailey (2008) argue that a doctor-patient relationship is needed for good communication. I felt very inexperienced and accepted the fact that the medical provide knew what they were doing however, I hoped that the doctors would have make something more, even though I understood that the patient had a right to say no to any form of medical treatment that was offered. I was concerned that Mr Jones would die if he did not eat or drink. The other nur ses on the ward did not seem to be as anxious to the situation as me. This resulted in me get quite distressed over the whole situation, even questioning myself if nursing was for me.I discussed how I felt with my mentor and this left me feeling very appointed. My mentor was a very experienced nurse who explained that nurses quite often find themselves in similar situations and most definitely feel the alike(p) way as I do. My mentor said that she felt I had done everything that I could have done with the patient and especially how I noticed that the patient was feeling angry and frustrated because he was having difficulties communicating. I found that my lack of confidence as a student nurse left me not knowing what to do if a patient is refusing treatment, eating and drinking. When Mrs Jones came to see her husband during visiting time, she told me that her husband had told her that he felt much happier that he now understood what was going on. Mrs Jones also said that the note pad was a fantastic idea for her husband to write things down and be able to communicate.If the situation arose again with a patient who has mouth or throat cancer, I would certainly ask during handover how well can the patient communicate, to ensure a good environment is created for the healthcare team and the patient.To conclude, I believe that there is nothing else that I could have done to help Mr Jones. However, I do believe that during the handover it would have been beneficial for everyone involved in the care of Mr Jones to be made aware of his difficulties with verbal communication. Nurses certainly need to communicate effectively with patients to provide safe and effective care, taking into consideration that there is difference and diversity and looking at every individual needs. Nurses who work with different cultures have a duty to learn the differences in cultural behaviour and patterns within these groups to prevent a cultural barrier. Listening, along with smiling a t appropriate times, showing a positive and genuine interest towards the patient, and have good eye contact will help to prevent barriers in communication. Another important factor is the way in which a nurse positions themselves when talking to a patient. If a patient is sitting, it may be appropriate for a nurse to come down to their level as not to seem to be standing over them, as this could be very disturbing and disrespectful to some patients. equalise and gestures can also go a long way into reassuring a patient. Just by touching a patients arm if they are upset and frightened can mean a lot to a patient. Along with this goes body language and showing respect that will hopefully continue to trust.ReferencesBaillie, L., (2009).
