Social and Cultural Impact on the Carnival of Rio de Janeiro Essay

Social and Cultural Impact on the Carnival of Rio de Janeiro - Essay Example â€Å"Rio de Janeiro, in Brazil is home to the world's most famous carnival, and what many people consider to be the world's biggest and best party. The basis of Rio’s Carnival is the samba schools, which social clubs are named after the famous Brazilian samba dance† (Richard 2011). Samba schools are found in various places of Rio de Janeiro, and competition between them is fierce. Members work all through the year to make the best floats, themes, costumes, and dance performances. â€Å"Education and rehabilitation are among the primary responsibilities that these samba schools undertake† (About Rio Samba Schools: Understand Overview of Samba Schools 2011). During the four day carnival, schools parade and struggle against each other in the Sambadrome, a building that can hold nearly 60,000 spectators. Millions of people get involved in merry making all through the city, especially on Rio's famous beaches, Copacabana and Ipanema. â€Å"Rio de Janeiro and the carn ival the two attractions are inseparable. Although the carnival in Rio is very commercial nowadays, it still is the carnival in Brazil, even though there are more authentic celebrations held elsewhere. Five days of samba and partying make the event as famous over the world as the World Cup or Olympics. Rio de Janeiro is also an attraction worth of seeing† (Tourism in Brazil Essay 2012). Social Impact on the Carnival of Rio De Janeiro: Rio de Janeiro is remembered for its strange natural beauty and excitement of popular culture. â€Å"Carnival has a different effect on each person, but it was created just with one objective for everyone, and that is to have a lot of fun, to forget our routine life, worries, responsibilities and to adventure at least once in our lives, because this experience no one will ever forget† (Kathyvargas 2004). The city is also marked by tremendous differences, reflecting a high degree of social disparity. The gap between the poor and the rich an d their close geographic nearness, characterized Rio. â€Å"Rio de Janeiro has major social problems, in the same neighborhood, such as Gavea for example, there is a difference that has developed over 60 years. Opposing realities are seen within a few meters of each other. On one side we have the upper class, with its mansions and high levels of education, and on the other side groups who in poor conditions, living in shacks, without even a basic education† (Social Problems in Rio De Janeiro 2012). This chasm of disparity makes many other impacts in the day-to-day city life. Crime, violence, police corruption, drug trafficking, deficiencies in health, inefficient transportation systems defective and education form the crux of Rio’s daily routine. The city has high levels of crime, particularly homicides. â€Å"Between 1978 and 2000, almost 50,000† (The Top 10 Most Dangerous City Breaks 2012) citizens were killed in Rio, the majority of victims being affected by stray bullets, and drug trafficking. There is a huge burden of teenage homicides, the age for the majority at risk in the drug gangs for and those who endure most from police fighting. â€Å"In 2010, Rio received 800.000 visitors during carnival which represents an R$ 950 million industry for the city† (Carnival of Rio De Janeiro 2012). Urban violence is an increasing problem that that has influenced every

Online Social Network Bring More Benefits Than Harm for Teens Essay Example for Free

Online Social Network Bring More Benefits Than Harm for Teens Essay Social networking is even used to prove the legitimacy or credibility of the individual. From entertainment, information to career improvement, social networking has practically changed the way people communicate and interact online. But social networks still have to face certain challenges especially on the users’ end since these challenges could harm users and the social network’s reputation. It is important for users of social network to consider these issues that surround the social network. By remembering these challenges, users will be able to protect themselves from negative repercussions on some issues on social network. Privacy as the Main Concern The number one problem users as well as social network administrators face everyday is security. It can happen in any given time with or without the user online. Attacks on different social networking website are always a possibility because the data protected by social networks are too precious to be ignored by attackers. Viruses, spywares and worms that aim to crawl through security protocols of social networks are constantly threatening social networks. Considerable time and resources are always spent by social networks in order to maintain privacy of their users. A single attack could make every user vulnerable to security related problems such as identity theft. Information Access Access to social networking websites varies. Some website will allow any user to access information of persons even though they are not part of the user’s network while some social network prohibit access to any form of information without confirmation from the profile owner. Problems regarding information access could be completely controlled by user but unauthorized access could still happen especially for those who are just starting to understand the rules of different social networks. Updated Notification Every social network provides real time notification usually through email if there are any changes in the user’s profile. But most notifications are very limited and they are usually on the positive things that happened on the social network. For example, when a request to connect is asked, the user will automatically be notified through email or any messaging system the user prefers. But social networks will never inform the user if someone willingly removes their connection. This is done to avoid confrontations between users which significantly affect the relationship. Misuse of Social Networks Unfortunately, there are those who use social network for scams and other illegal purposes. There have been reports around the world that social networks are used to spread rumors, lies or degrading messages that could affect the person’s reputation. â€Å"Cyber bullying† or an act of being hostile to another user online has also been observed in some social networks. This type of actions should never be allowed in any social network. Users have to be careful on the veracity of the data they receive and to take actions as soon as possible as soon as something undesirable is found on social networks. Protection for Children Aside from privacy and misuse of social networks, the vulnerability of minors is also a big problem for all social networks. While some social networks are geared towards adults, most social networks are open to everyone – including minors. Unfortunately, minors on social networks could become targets of sexual predators that can cloak their real identity in different social networks. While some legislators have taken steps in preventing these offenders from using social networks these efforts could be easily curtailed especially when the offender is more than familiar with the internet.

Optically Active Pharmaceutical Compounds Biology Essay

Optically Active Pharmaceutical Compounds Biology Essay The molecules which are non super imposable mirror images of one another are termed as chiral. These are a pair of enantiomers and are diasymmetric as well as optically active. Since they promote optical rotation, these enantiomers are also known as optical isomers. These chiral molecules consist of a tetrahedral carbon atom which is attached to four different groups. The carbon atom is the stereogenic or the asymmetric centre of the molecule. The enantiomers are similar in their physical and chemical properties in an achiral environment. Enantiomers have different biological properties. This influences the efficacy and the toxicity of the compounds. Usually, one of the enantiomers is bioactive and the others may be inactive or toxic. Example, Verapamil is a calcium channel blocker used for the treatment for blood pressure, angina. The (S) isomer treats the increase in BP more effectively than the racemate form. The (R) isoform inhibits resistance of cancer cells to anti cancer drugs (Crosby, 1991). The enantiomerically pure compounds are very useful and vital in the pharmaceutical and agrochemical industries. It has also been shown that the optically pure and chiral compounds should be used rather than mixture of enantiomers. The optically active pure compounds are used to produce antibodies, hormones, anti inflammatory, amino acids, vitamins, anti cancer drugs, cardiovascular drugs. Chiral chromatography or ligand exchange chromatography was an analytical technique used for separating enantiomers. High performance liquid chromatography whereby chiral stationary phase is used was efficient in separation of enantiomers. The optically active ligands like amino acids are bound covalently to a solid support, thereby forming a chiral stationary phase. Various amino acid derivatives like N -(3,5-dinitrobenzoyl) phenyl glycines are also used.(Pirkle and Pochapsky,1987). The major advantage of chromatography is that it results in high enantiomeric excess and is suitable on the analytical scale. However, its drawback is that the scale up is difficult. The production of enantiomers for optically active drugs may be produced by different methods. Pure compounds are recovered by various extraction techniques from chiral compounds (alkaloids, carbohydrates) exist as pure enantiomers naturally. Fermentation of cheap substrates which are available in abundance (like molasses and sucrose) was a widely used source of single chiral molecules lactic, tartaric and L- amino acids and also for complex substances which include vitamins, antibiotics and hormones.(Buchta,1983). Optically pure compounds may be prepared from inactive starting materials by asymmetric synthesis and resolution of racemates. In the process of asymmetric synthesis (Stinson,1993) an enantiomeric reagent or catalyst is used for carrying out a specific reaction on an achiral substrate (prochiral) to produce a single chiral product. Overall, it is a selective technique as it leads to product selectivity. Its disadvantages are that it may be expensive due to the numerous steps involved and also because of the use of costly enantiomeric reagents. It is cheaper to produce a racemic mixture and then separate the enantiomers by physical methods like kinetic resolution or diastereomeric crystallization. Covalent derivatives are formed using optically pure resolving agents in the diastereomic crystallization method. The drawback is that it is wasteful since the unwanted isomer may be discarded. On the other hand, kinetic resolution is based on the principle that two enantiomers react at vari able rates in the presence of a chiral catalyst like an enzyme. This method involves product selectivity. Biotransformation has also become a key technology used to produce chiral substances. It was used by many companies Eg. Celgene Corporation developed procedures to produce amines by using amino transferase (Celgene corporation,1990).The main advantage of this procedure is that it allows 100% theoretical conversion of the substrate into the final product. Membrane chirotechnology is also a widely used method for producing optically pure isomers. In this procedure, the membrane itself maybe intrinsically enantioselective. This means that the membrane represents a chiral system that separates the desired isomers on the basis of spatial conformation. On the other hand, a membrane separation process may be combined with kinetic resolution by making use of an enantiospecific biocatalyst.That is, the membrane helps in the separation of the product from the substrate on the basis of their chemical properties like solubility. Enantiospecific catalytic membrane reactors may also be used. These comprise of membrane processes which are advantageous as they have the ability to work in a continuous mode and enormous amounts of material could be processes at once. The competitive production of chiral substances requires a large scale, cheap process for the production and separation of the enantiomers. Eg. Pyridoxal phosphate dependant lyase and transferase were used as catalyst in the synthesis of L- amino acid via the carbon carbon bond formation. (Sheldon,1993) The widely used enantiospecific membrane reactors are ultrafiltration hollow fibre membrane reactor (Responsible for production of L phenylalanine by using dehydrogenase catalyst (Schimdt et al, 1987) ) immobilized enzyme membrane reactor, packed bed continuous bioreactor, biphasic membrane reactor etc. Ultra filtration, electrodialysis and membrane extraction are common separation processes that are combined with biotransformation. Matson and Quinn(1979) showed the optimization in production of amino acids enantiomers and studied the separation of L amino acids from the racemate solution by making use of an impregnated liquid membrane alone with an enzyme immobilised membrane. Production of L-phenylalanine from racemic mixture of D,L phenyl lactate was shown by 2 consecutive biotransformation in an enzyme membrane reactor whereby the enzyme and cofactor(NAD/H) had been compartmentalised behind an ultra filtration membrane.(Schmidt et al, 1987). Intrinsically enantioselective membranes are also widely used. Substances which are optically active can be separated on the basis of there physical stereo selectivity. Polymeric membranes having the enantioselective properties intrinsically may be prepared making use of chiral polymers or by chiral modifications of the achiral porous membrane in the presence of chiral recognition agent like cyclodextrins, cyclophane and oligopeptides. In order to prepare the enantioselective membranes, optically active polyacryl amides and cellulose derivatives may be used. Yoshikawa et al,1996, showed separation of tryptophan, phenylalanine and alanine by ultra filtration using the chiral selector which was molecularly imprinted polymeric membranes(DIDE derivatives). Enzymes have the ability to catalyse a broad spectrum of chemical reactions with great efficiency and selectivity under mild and environmentally friendly conditions. By exploiting the selectivity of enzymes for one form of the enantiomer of a racemic mixture, the enantiomerically enriched compound can be obtained by biocatalytic resolution.(Thomas et al,2002) Most commonly, the hydrolytic enzyme are used since they display a range of advantages like stability, specificity, no requirement of cofactors. Among hydrolases, lipase is most commonly used because of high enantioselectivity, commercial availability and good stability in various media.(Seung Hwan et al,2004) Recently a new technique was introduced to display the peptides and proteins on the surface of gram negative and gram positive bacteria, yeast or mammalian cells. This was done by fusing the peptides to surface anchoring motif; and the technique is known as cell surface display. The cell surface display lipase proved to be an excellent biocatalytic system for the kinetic chiral resolution of the racemic compound. Recent advances have shown the use of enzymes in the synthesis of optically pure drugs and biologically active compounds. Enzymes have the ability to distinguish between the enantiomers of racemic substrates. Various strategies have been developed to improve the stereoselectivity of resolutions catalysed by the enzyme. This includes modification of the substrate, recycling of the product and altering the reaction conditions. By making use of these strategies, enzymes with modest stereoselectivity can also be used but only one enantiomer is produced with high yield. Enzyme can catalyse transformations with high region selectivity and chemo selectivity under mild reactions. This is important in the modification of chiral drugs. Eg. Penicillin acylase causes the hydrolysis of benzyl penicillin without affecting the beta lactam ring and allows the industrial preparation of 6-aminopenicillanic acid which is a precursor for many semi synthetic penicillins. Enzymes (hydrolases) have success fully been used in the synthesis of chiral pharmaceuticals, however modern methods of protein engineering and industrial microbiology help in the production of enzymes which are more inexpensive, stable with broad substrate specificity and high stereoselectivity.(Alexey L.Margolin,1993) Catalytic asymmetric synthesis is the asymmetric synthesis that is catalysed by chiral (transition) metal complex. The reactions that are involved are Redox transformations or carbon carbon bond forming processes that complement enzymatic hydrolytic process. The three types of chemo catalysts that exist are heterogenous metal catalyst, homogenous complex and soluble chiral acid or bases. Emil Fishers work on asymmetric induction which was based on cyanohydrin synthesis was the first reaction subjected to asymmetric catalysis. Enantiomerically pure amino acids, amino alcohols, amines, alcohols and epoxides play an important role as intermediates in the agrochemical and pharmaceutical industry whereby high level of purity and a large quantity is required. The enantiomerically pure active compounds help in improving the economics of the process, thereby leading to reduced quantities applied and less amount of an environmental impact. Chemical process for the manufacturing of amino acids: Even though asymmetric syntheses of amino acids are known (Michael Breuer et al,2004), no economical process has been developed. Bucherer Bergs sub type which is Strecker synthesis was employed for the industrial manufacturing of the racemic amino acids. The alpha amino nitrile is produced from hydrocyanic acid, ammonia and an aldehyde and may be hydrolysed to the amino acid directly or in the presence of carbon dioxide it gets converted into hydantoin. The hydantoin is then subjected to hydrolysis in a basic media to give the racemic amino acid. Another route to the racemic amino acid is amido carbonylation in the presence of a transition metal. Although, there is no commercially viable chemical process for the synthesis of enantiomerically pure amino acid, the production of racemic amino acid is still of great importance because the racemates may be converted to enantiomerically pure compounds by various biocatalytic methods. The catalysts used in the biotransformation are metabolically inactive cells or isolated enzymes. It is the method of choice for the production of enantiomerically pure D- amino acids and various other non natural amino acids. Lyases may be used as biocatalysts in the production of L- Aspartic acid from fumaric acid (Beller et al,2000). Amino acid dehydrogenase (deaminating amino acid oxido reductase) allows enantioselective biotransformation on an industrial scale. These enzymes have low substrate specificity due to which non natural compounds may also be transformed. In addition, they also require co substrates which help in supplying the hydride ions for the reduction of Schiff base. There is also a chemo enzymatic method for amino acid synthesis. In this, L- amino acid gets oxidised by L- amino acid oxidase. Imine (intermediate) gets reduced by Pd-C in ammonium formate buffer. In the resulting racemic mixture, only L enantiomer is utilised by oxidase where as the D- enantiomer accumulates. Therefore, the enantiomeric form of the amino acid which is produced depends entirely on the specificity of the oxidase. The enantiomerically pure amino acid can also be prepared by the racemate resolution. Eg: L and D amino acid can be prepared with the Hydantoinase-carbamoylase system. Production of carboxylic acids: Carboxylic acid can be isolated from natural sources(chiral pool).Naturally occurring chiral compounds obtained from the chiral pool are an alternative to the synthesis of enantiomerically pure products. An examples of a chiral carboxylic acid that is isolated from the natural sources is L (+) tartaric acid (Mitsugi et al,1978). During the fermentation of grape, the isomeric form of tartaric acid separates out as tartarate (potassium hydrogen tartarate).On reacting with calcium chloride or calcium hydroxide and sulphuric acid, isomeric tartaric acid is released; gypsum and yeast residues occur as the by products. Natural carbohydrate building blocks were used for several decades for the preparation of sugar acids which were enantiomerically pure. Another method is the classical chemical synthesis which involves crystallization with enantiomerically pure amines. The enantiomers of the racemic carboxylic acids are known to separate by fractional crystal lization of the diastereomeric salts which are formed with the enantiomerically pure amines. Eg: Thiazolidine carboxylic acid (enantiomerically pure), an intermediate in the synthesis of CP-060- S is isolated by the resolution of racemate with N- benzyl-1-phenylethylamine. (Pompejus et al, 2001) Production of amines: The chemical process involved is the crystallization with chiral carboxylic acids. Isolation of enantiomerically pure amines can be carried out by the crystallization of diastereomeric salts of chiral carboxylic acids with chiral amines (Jacques et al,1980). Thus (R) or (S) 1- phenylethlyamine may be produced on an industrial scale by the crystallization with either (R)- mandelic acid or (S)- malic acid. Mandelic acid was shown to be an important resolving agent for numerous numbers of amines. Dutch resolution is a variant of the classical racemate resolution. In order to reduce the search for an appropriate resolving agent for an amine through combinatorial approach, a mixture of many optically active acids were used. The salt that was precipitated contained several acid anions. Production of optically active amino alcohols: (S)-2-Aminobutanol is an important amino alcohol intermediate which is used for the synthesis of ethambutol (tuberculostatic)and it must be administered in its enantiomerically pure form as it may lead to blindness. The enantiomerically pure form can be obtained from the racemate by carrying out the crystallization with L-Tartaric acid.(Sheldon et al,1993) Production of alcohols: The main process involved was the asymmetric hydrogenation of ketones. Noyori et al showed the development of asymmetric hydrogenation of keto esters and ketones. The catalysts used were ruthenium complexes of binap and derivatives like tol-binap (Akutagawa,1995)and segphos. The biotechnological process is mainly the enzyme catalysed resolution. For the resolution of racemate alcohols, enzymatic acylations were developed in early 1980s.The racemic alcohols are made to react with an acylating agent under enzyme catalysis whereby one enantiomer is unconverted whereas the other enantiomer is esterified. The biocatalysts used are bacterial and fungal lipases. Production of epoxides: This includes sharpless asymmetric dihydroxylation. The route to the formation of chiral epoxides is based on the optically active diols which may be converted to their respective oxiranes. Another method is the Jacobsen asymmetric epoxidation which is based on (salen) manganese III precatalyst and the hypochlorite is used as the stoichiometric oxidizing agent. The chemical processes may be compared with the biotransformation with respect to the environmental impact and economic efficiency. The drawbacks of the chemical routes are solvent emission or toxicity of certain compounds. On the other hand, chiral technologies are developing rapidly. Highly versatile technologies and procedures are introduced. Most chiral intermediates are produced in minute quantities. Therefore, the criteria that should be considered for the methods introduced are that they should have a broad substrate spectrum, not require specialised equipment and have a cost effective access to a range of products. It is not possible to make general conclusions about the superiority of one type of technology in comparison with the others. The most economic technique will depend on their component which is why each case should be investigated individually. However, in the overall process, the chiral step should be introduced as early as possible but this may be hindered by other factors like racemisation of the unwanted isomer. Membrane chirotechnology is also an emerging technique having several advantages with respect to the purity of simple isomers, productivity and ease of scale up. These techniques have mainly been used at the laboratory scale. Application on a large scale needs more investment especially in developing the experimental set up rather than investigations which have been carried out on chirality that have been developed in the chromatographic field.

last don :: essays research papers

Mario Puzo, the author of many famous mafia books, such as the Godfather, writes the best-selling novel called, â€Å"The Last Don†. â€Å"The Last Don† is about a mafia don, Domenico Clericuizio, who was making arrangements, on the day his grandson and nephew were being christened, for his family to get out of the business and go straight. Don Clericuzio is the head of the most powerful crime family in America. He is a greatly feared man who has built a billion dollar empire, and believes that every debt must be paid and that family comes before anything.  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  The book, which has a very intresting plot, is a hard book to read. I liked this book for many reasons, but I also disliked it. Mario Puzo, trying to make the book as realistic as possible, had the speech in the book sound like a bunch of nonsense. The characters in the book, sounded very uneducated and it took some effort to think about what they meant and were trying to say. I guess it would be easier to watch the story on the television, but reading it is very confusing. I rarely ever read for pleasure, and I guess I picked the wrong book to try it out with. This book had me very frustrated with the language, and it took me a couple of times to get what was going on in the story.   Ã‚  Ã‚  Ã‚  Ã‚  One of the intresting things about the book, as well as most of the mafia-based stories is the way Puzo can take characters that are big in crime and violence and turn them into likeable characters. In this novel, the majority of the characters are likeable. Cross De Lena, the don’s great nephew, had feelings for Athena, the most beautiful and talented woman in Hollywood. His feelings grew so strong that Cross decides to make movies. This was one of the most surprising part of the novel because Cross’s desire to make movies causes him to take action without his family’s approval, which in return is a major problem that shocked the family.   Ã‚  Ã‚  Ã‚  Ã‚  This book is different then other books I have read because, usually I don’t get to pick out a book to read, it is usually assigned to me, so when I started to read a book that interests me, I thought I would be intrigued. I enjoyed reading this book at times, but I felt it was a hard book to get in to.

Cinderella Argument Paper Essay

From generation to generation stories are always changing. Fairy tales like Cinderella go from mean step sisters to nice sisters, fairy god mother to a tree. After reading 5 different versions of Cinderella I had to choose which I would decide to read, above the others to my favorite child. After difficult thinking I have chosen the Walt Disney’s version of Cinderella for many great reasons. I have chosen the Walt Disney’s version because I feel it is the most fitting for children over all the others which are best suitable for older teens. Walt Disney’s version is the ideal story beginning with â€Å"Once upon a time† and ending with â€Å"lived in the palace and were happy ever after, too†. The fairy tale story of pretty girl by the name of Cinderella who lived with her step mother and 2 step sisters who treat her horrible having her cook, clean, and bake, meanwhile having no rights to do anything without her step mother’s permission. A great ball was given by the king, for the prince and every young girl in the kingdom were invited, even Cinderella†¦ Although the nasty step mother told her no. Cinderella cried her heart out, until an older woman appeared in front of her telling her, I am your fairy godmother and she said â€Å"You are going to the Ball†. Before you knew it with the powers of the step mother Cinderella was beautifully dressed and a coach pulled by horses was ready to take her. Cinderella was told that at the stroke of midnight the powers would be gone and she would, means she would have to be gone. Although no one knowing who she was, she caught the prince’s eye. Forgetting to keep her eye on the clock, at 12 she rushed out losing one of her glass slippers. Every girl in the land tried hard to fit into her lost slipper, until Cinderella was forced to try it on, and it fit her perfectly. Cinderella became the prince’s bride and lived happily ever after. All similar, but yet different, In â€Å"Cinderella†, by Anne Sexton there are minor differences that pointed out to me making me not choose this particular story for my child. Besides the story being set up like a poem, I found this to be more difficult for a younger child to understand. This story starts off stating 4 extremely short but successful stories then leading into Cinderella which in my opinion isn’t needed to understand the story. As the story goes on in line 32 they refer to Cinderella looking like Al Jolson, which no kid would understand causing another story within a story about who Al Jolson is. In Walt Disney’s Cinderella, Cinderella is forced to try the slipper on, after her sisters try it on and are unsuccessful. In both â€Å"Cinderella† by Anne Sexton, and â€Å"Cinderella† by Jakob and Wilhelm Grimm, the step sisters decide to cut body parts to fit into the slipper. One cutting a toe off and the other cutting part of her heel off, until not long after, with help from the fairy god mother, or Cinderella’s mother that the prince finds out. I feel that blood and cutting off body parts because you don’t fit the characteristics you want so you can be with a man isn’t a good trait to teach your children. Lastly In both â€Å"Cinderella† by Anne Sexton, and â€Å"Cinderella† by Jakob and Wilhelm Grimm, the fairy (mother) were doves who pecked the eyes out of both step sisters for the way they treated Cinderella. The step sisters treated Cinderella horrible but did not deserve to have their eyes pecked out. This teaches children a bad lesson as well as giving them a horrible view to picture. Clearly you can now understand why I have chosen what I have. After reading all 5 wonderful versions, Walt Disney’s Cinderella adapted by Campbell Grant is the best for any child, especially mine. After reading a happy story there is a lot less you’ll need to explain to your child that is unnecessary to be explained to until they are older. The Walt Disney’s version I feel it is the most fitting for children over all the others which are best suitable for older teens.

Cloud Services Go Mainstream

Case Study 3. 4 – Salesforce. Com: Cloud Services Go Mainstream 1. How does Salesforce. com use cloud computing? Salesforce. com provides customer relationship management and other software applications using the software-as-a-service business model over the Internet. Cloud computing, also known as on-demand computing, eliminates the need for a business to make large up-front hardware and software investments and reduces the time to implement new programs. Subscribers to Salesforce. om don’t have to purchase or maintain any hardware (albeit personal computing devices) nor do they have to install any special operating systems, database servers, or application servers. Other than the monthly user subscription fee, businesses reduce their licensing and maintenance fees. Users access the Salesforce. com cloud through a standard Web browser or a mobile handheld device. Businesses using the Salesforce. com’s cloud have an easier time scaling their system as they increa se or decrease their workforce – they adjust the number of subscriptions to the cloud.Salesforce. com offers some customization of its software so a business can adjust the software to unique business processes. It offers three types of clouds: Sales cloud, service cloud, and the custom cloud. The sales and service clouds help businesses improve sales and customer service. The custom cloud provides a venue for customers to develop their own applications for use within the broader Salesforce network. 2. What are some of the challenges facing Salesforce as it continues its growth? How well will it be able to meet those challenges? Challenges include: Increased competition both from traditional industry leaders and new challengers hoping to replicate Salesforce’s success -Expanding its business model into other areas -Ensuring the system is available 24/7 with no outages -Defending the system against security breeches Salesforce is answering the first two challenges by pa rtnering with Google and combining its services with Gmail, GoogleDocs, Google Talk, and Google Calendar to allow its customers to accomplish more tasks via the Web . Salesforce. comand Google both hope that their Salesforce. com for Google Apps nitiative will galvanize further growth in on-demand software. By partnering with Apple, Salesforce. com can expand its applications to iPhone users who will have access to their data anywhere any time. Through its partnership with Amazon. com, Force customers can tap into Amazon. com’s cloud computing services that can handle â€Å"cloud burst computing† tasks that require extra processing power or storage capacity. Salesforce opened up its Custom Cloud (also known as Force. com) application development platform to other independent software developers and listed their programs on its AppExchange.The company introduced a development tool for integrating with Facebook’s social network that allows customers to build appli cations that call functions at the Facebook site. Small businesses can go online and download software applications, some add-ons to Salesforce. com and others that are unrelated. In order to grow its revenues to levels that industry observers and Wall Street eventually expects, Salesforce will need to change its focus from selling a suite of software applications to providing a broader cloud computing â€Å"platform† on which many software companies can deliver applications.To ensure system availability, Salesforce. com provides tools to assure customers about its system reliability and also offers PC applications that tie into their services so users can work offline. 3. What kinds of businesses could benefit from switching to Salesforce and why? Small to medium-size businesses are probably the most likely ones to switch to Salesforce. com because of cost factors and the lack of having in-house resources to provide the same level of computing capacity.Businesses that are tr ying to increase the sophistication of their computing capabilities could also benefit from switching to Salesforce as long as the two are compatible. Businesses that rely on smart customer management would benefit greatly from using the tools available at Salesforce. com. Also companies that have small sales and marketing teams can benefit from the software-as-a-service business model. 4. What factors would you take into account in deciding whether to use Saleforce. com for your business?Businesses should assess the costs and benefits of the service, weighing all people, organization, and technology issues. Does the software-as-a-service application integrate well with the existing systems? Does it deliver a level of service and performance that’s acceptable for the business? Does the SaaS fit with the business’ overall competitive strategy and allow the company to focus on core business issues instead of technology challenges? 5. Could a company run its entire busine ss using Salesforce. com, Force. com, and App Exchange?Explain your answer. Depending on the type of business, a company probably could run its entire operations using Salesforce. com, Force. com, and App Exchange. All four major functional areas of a business are supported: Sales and Marketing, Manufacturing and Production, Finance, and Human Resources. There are dozens of applications available to fully support all of these areas. It would be a matter of integrating the software from Salesforce. com and App Exchange with any existing legacy systems within the business.
