Structure analysis for NEA - Essay Example President Barrack Obama has emerged revised policies to approach the challenges of VC fund flow structure of the country with appropriate revision of all existing norms to benefit the emerging companies. NEA environment of the liquidity of VC’s fund is described better by Porter’s Five Forces which identifies five different constraints in the fund governance of an emerging company. Firstly, the status of a company needs to be largely approved and of a huge size of operation to enter into NEA’s investment stream. Legal formalities of many of the entrants become complicated as they need to produce assurance of liquidity to the investors. Secondly, the superior power of investors over the company stands on the way of its operation. Investors are usually very selective about the choice and manner of business. This rigidness is somehow dissolved in the gradual course of longer term of the investment and illiquidity of the fund owing to low growth rate of the company’s income. Another force that suspends the VC’s fund flow is threat of substitutes. Thus the entrepreneur’s power is seized by the influence of investors as they are the decisive force behind the work. At the foremost stage, the VC fund flow was largely hit by the rapid growth in low flexibility and illiquidity which resulted in unethical entry of rival groups in the operation of similar activities. In the trial of accumulating funds, more than 650 Funded Companies, over 165 IPOs and as many as 265 Mergers and Acquisitions were drawn in favor of the venture capital stream. Thus formation of enhanced capital funding from various fields encouraged the process of forming top 100 companies aligned with an NEA found opportunity for employing over 300000 people and gathered their efforts positively generate $100bn in annual revenues. A great achievement of NEA stream was that it associated over 65 investment

Damned If You Do Essay In my Chemistry class, there are two students who always ask make remarks or ask questions about the topics discussed: a male and a female. When the male student asks questions, the people in my class sit quietly and listen to the professor’s explanation, but when the female student asks questions, the class—including myself— gets annoyed. They begin to roll their eyes and sneer. Even my professor seems to be annoyed at times. Often I hear my classmates complaining about her during break. They nag about how much she interrupts class with her foolish questions and interpretations, yet no one complains about the male classmate. I thought to myself, â€Å"Maybe he asks better questions than she? † But after a few weeks I began to realize that the intelligence of their questions and comments tends to be the same. So why do my classmates favor the male student’s remarks over the female student’s? Everyone has their own way of saying things, however the way we hear what a women says is often completely different in comparison to how we would hear it if a man had said it instead. When hearing both genders communicating, we unintentionally put males above females. We look at men as more powerful than women. In Deborah Tannen’s book, You Just Don’t Understand, she explains that the reasons for this starts at a very young age. Girls were raised to never boast. Tannen says, â€Å"Girls learn that displaying superiority will not get them what they want—affiliation with peers. For this, they have to appear the same as, not better than, their friends† (218). Females look at boasting as â€Å"showing off† and â€Å"rude†, and feel they will be rejected if they do so. They rarely compare themselves to others. In fact, women try to keep the status between them mutual. The best example is my little sister, Julie. When she plays with her friend Natalie, they always play the same character. They will agree to be â€Å"sister princesses in a big castle. † On the other hand, when I see her play with her friend Jake, he always insists on being superior to her. He says things such as â€Å"I’ll be Batman and you’ll be Robin,† immediately taking the higher status. Boys feel that if they don’t act dominant and take charge people won’t take them seriously. Naturally we expect women not to boast, while with men we don’t seem to care. If a woman told a group of people she was a founder of a huge company worth millions of dollars, they would think she was â€Å"showing off† and the group would automatically leave her out of the conversation. If a man were to say the same thing—because we are so used to them boasting—we would not look at it as â€Å"showing off†. We would think highly of him. This is why men and women are judged differently even when they speak the same way. Tannen says, â€Å"If a linguistic strategy is used by a woman, it is seen as powerless; if it’s done by a man it is seen as powerful† (225). Since females don’t try to be at a higher status, their speech is often ineffective. Along with women not addressing a higher status, they also do not ask for something directly. They are more covert when asking for a favor. When my mom says, â€Å"It would be nice if someone would put the dishes away for me,† most of the time I don’t. Because she is asking indirectly, I don’t see the power in her question. On the other hand, if my dad says â€Å"Hey†¦ put those away for me,† I automatically listen. Although they were both implying the same thing, my mom’s statement was powerless because it was polite and indirect. Females use â€Å"tag questions† (227-28), such as â€Å"That’s a nice dress, isn’t it? † The â€Å"tag question† makes women seem unsure. Women don’t mean to sound hesitant. They say â€Å"Isn’t it? † expecting the other person to say â€Å"yes† or â€Å"no,† and therefore starting a conversation. Tannen says, â€Å"[P]eople expect women to use tags† (228). We expect women to be unsure, and as a result, when they make statements or ask questions, we assume they don’t know that they are talking about. Researcher Patricia Hayes Bradley says, â€Å"When women used tag questions and disclaimers, subjects judged them as less intelligent and knowledgeable than men who also used them† (qtd. in Tannen 228). In other words, because of the different stereotypes of men and women, we have distinctive attitudes towards what they say, and we make men dominant. Looking back at the issue in my Chemistry class, I see why I found the female student aggravating. When comparing her to the male classmate, I unconsciously looked at her as lower than him. Both males and females become accustomed to this power vs. powerless ways. It becomes everyday life. People are less likely to pay attention to an idea that is raised by a woman who doesn’t assert her status, therefore making us unconsciously look at them as below men.

Analysis of Web Service Efficiency

Analysis of Web Service Efficiency Abstract Web service standards used nowadays are Extensible Markup Language based and the important technology in communication between heterogeneous applications are over Internet. Thereby selecting an efficient web services among numerous options satisfying client requirements has become a challenging and time consuming road block. The path for the optimal execution of all the user request is done using the Hidden Markov Model (HMM). The results have shown how our proposed methodology can help the user to select the most reliable web service available. Our analysis is about creating a cost effective servicing mechanism for web services, if effectively implemented this concept will reduce the need for network engineers in maintenance of web services. As a result of the parallelism technique used in this analysis significant reduction in RT and increase in composition speed has been observed. Keywords: Hidden Markov Model (HMM), Extensible Markup Language, Web Services, Service Quality Architecture (SQA)   1. Introduction In the Service Web the feedback of customers constitutes a substantial component of Web Service trustworthiness and reputation, this in turn affects the consumer service uptake in the future. All that we presents here is an approach to predict and assess the various reputations that are prevalent in the services oriented environment that is prevalent. All the web services enable computer-computer (c2c) communication in a heterogeneous environment, hence they are very suitable for an environment such as the internet. People can use the standardized web service model for rapid design, implement and extended applications. Many enterprises and corporations provide different web services to be more responsive and cost-effective. All activities that are composite services in nature may be defined by the graphs of control flow and the after coming data graphs. As a service provider, the foremost importance is for the bound(upper), the mean RT of a request given some request load and some architectural environment. Furthermore, this computation should be only performed before the actual deployment and usage of the service. In exceptional cases of service thats of composite nature this performance of the service depends on only the hypotheses about all the invoked service that are elementary in nature. Component approaches another very important benefit is reuse. In the web service definition language all the service that are of elementary nature are conceptually limited to relatively very simple features that can be only modeled by a collection of operations that co exist. Moreover, in due to the application kind its very much necessary to combine a set of all the web services into a single composite web servic e. All of the proposed methodology exploits is the ideas from the Software Architecture- and Component-based approaches to software design. The process of web service selection and discovery of system is essential to provide the clients with proper results and that fulfills their requirements. Its impossible for anybody to fulfill the task without considering all the ranking relations that exist between thousands of various available candidates that have similar functionalities. Thus, ranking is a fundamental process of a Web service selection system, as this integrates all the results thats gathered from previous stages and presents them to those requested. This paper is focused on the various ranking process by considering users SQA requirements. Hidden Markov Model (HMM) A Hidden Markov Model is very well related to the study of how likely or unlikely things are going to happen in the graphical model that is available and well suited in dealing with a sequence of data that are related. The very basic way of thinking this is that we have a set of states, but the road block is we wouldnt know the state directly (this is the reason that makes it hidden). Instead of this, we can only make a state, but we are not in position to tell the state of proceedings for sure. Addition to this is that there are changes (from one thing to another) that is in between states. Each of the change (from one thing to another) between the states is also called as a chance. Sometimes these are known, sometimes they are not known. These states are very flexible instrument that can be put to use not just for clarification purpose but also for (division of something to smaller parts) the purpose and even to create or see or hear things that arent there data. The property of ge nerative works by training a model on this data and then randomly creating chances of (instance of watching, noticing or making a statement) and change (from one thing to another). In this way, you can create data using a hidden markov model. 2.1 Definition Our model of HMM is defined by specifying the following variables: X = {x1, x2, , xn} = set of states Z ={z1, z2, , zm} = the output alphabet à Ã¢â€š ¬(i) = probability of being in state xi at time t = 0 A = transitional probability = {aij}, where aij= P r[entering state xj at time t + 1 | in state xiat time t]. Note that the probabilities of going from state i to state j doesnt depend on the previous states at earlier times. B = output probability ={bj(k)}, where bj(k) = P r[zk at time t | in state xj at time t]. For the purpose of giving an example, lets say that we have two biased coins, which we are ipping, and an observer is seeing the results of our coin ips (not which coin were ipping). In fact, suppose that what we are actually doing can be described by Figure1.Here, the states of the HMM are q1 and q2 (the coins), the output alphabet is fH; Tg, and the transition and output probabilities are as labeled. If we let(q1)=1and(q2) = 0 then the following is a example of a possible transition sequence and output sequence for the HMM in the following diagram. We can easily calculate probabilities for the following events. 1. The probability of the above transition sequence: Pr[x1x1x1x2x2x1x1]= à Ã¢â€š ¬(x1)a11a11a12a22a21a11à ¢Ã¢â‚¬ °Ã‹â€  0.025 The probability of the above output sequence given the above transition sequence: Pr[HHTTTTH]|(x1x1x1x2x2x1x1)] = 2/3,2/3,1/3,5/ 6,1/3 ,2/3 à ¢Ã¢â‚¬ °Ã‹â€ 0.023 The probability of the above output sequenceandtheabovetransition sequence: Pr[(HHTTTTH)^(x1x1x1x2x2x1x1)] à ¢Ã¢â‚¬ °Ã‹â€  (0.025).(0.023) à ¢Ã¢â‚¬ °Ã‹â€  5.7 ÃÆ'- 10-4 2.2 HMM Applications Classification: speech recognition (time series), handwriting recognition (sequence of points), patterns and motifs in DNA (sequence of characters), analyzing video sequences. Modeling transitions: road snapping to work out which segment the user was most likely on (a sequence of points). Generation: text to speech (another time series application). Calculating the transition probability depends on the problem you are trying to address. In some cases (e.g. road snapping) you can compute it directly from the data. If you know the observation probabilities, then working out the transition probabilities is relatively easy (it comes down to finding the path that maximizes the observation probabilities and doing a count to get a measure of the transition probabilities). The most popular of all probability estimation approaches for HMM is the Baum-Welch algorithm, which allows the estimation of both observation and transition probabilities simultaneously. 3. Service Quality Architecture (SQA) The most important Service Quality Architecture that is used in this paper are RT, cost of execution, availability of space, all the reputation and the successful rate of execution. The RT can be defined in quite a few ways. For instance, RT can be stated as the time in between the sending of request and that of receiving the response. This is the period that involves all the receiving request of message time, QT(queuing time), ET(execution time) and receiving RT by the requester. Measuring these time sections is very difficult because they depend on network conditions. Alternatively, it can be measured as the time between receiving request by service provider and sending response to service requestor. This time it includes QT and ET only affected by the workload of the web service. This is the value that must be continuously updated in each and every web services because of the work load thats of changing nature and web service may change during the work time. Execution cost of this process is a fee received by the service provider from the service requestor during each and every execution. The fee for this is determined solely by the service provider and can change due to the web service providers financial policy at that moment. The availability is a very important degree, that is a web service is accessible and ready for immediate use at any given point. From service requester for each execution. This fee is determined by service provider and may change according to web service providers financial policy. Availability is the degree that a web service is accessible and ready for immediate use. 3.1 SQA Notations The Service Quality Architecture used in this paper is summarized in Table1: SQA Description RT It is the time between receiving and sending request EC Execution cost request Availability Up time Up time down time Reputation Repi Total no.of usage Successful ER No.of successful request Total no.of request Descriptions of notations used in this paper are as follow: m: number of tasks. n: number of candidate web services for each task. pi: i-th atomic process of a composition schema (1 à ¢Ã¢â‚¬ °Ã‚ ¤ ià ¢Ã¢â‚¬ °Ã‚ ¤ m). wsij: j-th candidate web service for the ith atomic process, (1 à ¢Ã¢â‚¬ °Ã‚ ¤ ià ¢Ã¢â‚¬ °Ã‚ ¤ m , 1 à ¢Ã¢â‚¬ °Ã‚ ¤ j à ¢Ã¢â‚¬ °Ã‚ ¤ n). d: index of SQA . wd: weight of the d-th SQA constraint defined by a client. Cond:permissiblevalueofthe d-th SQA (constraints). Aggd: aggregated value of the d-th S Q A of a composition plan. bij: binary decision variable (0 or 1). If bij=1 then j-th candidate web service is selected for i-th process. 3.1 Aggregation Value of SQA Generally, composition plans are constituted from serial, cycle, XOR-parallel and AND-parallel execution patterns. According to the definition of SQA, the aggregative value of web service composition is calculated regarding to its workflow pattern. The description and aggregation values of workflow patterns are discussed below. For the negative criteria, all the values are scaled to equation 2. For positive criteria, all the values are scaled to equation 1. In our paper the values of n SQA attributes of a service S as a vector: Qs = (Qs1, Qs2, ,Qsn) are modeled and all the value of SQA requirement requested by a consumer are vector Qr = (Qr1, Qr2,Qrn) are considered. All the consumers preference values thus are set on SQA attribute that are each in a vector pr = (pr1,pr2,,prn)where pri[1,n].Thus if a consumer has no preferences over an attribute, n will be considered the default preference value for that specific parameter. Related Works The times of server for the database of composite nature Web services have been examined in full detail, this follows the fork-join execution model. The proposal of the author here is that while performing a join operation or execution, the servers with slow RTs will be eliminated to maximize the performance of the server. All the work here is the more orientation towards examination of the fork-join model thereby to understand the resulting merger of data from various servers. All the work in this domain regarding the performance of the Web services is more inclined towards the composite web services and their RT. When the execution of a composite service that have been examined as a fork-join model. Thus here in the model of the states that a single application in the Internet that invokes many different Web services that are in parallel and thereby gathers their responses and from all the launched services to return thereby, all the results to a client are not affected in general. The perfect explanation of the fork and the join system, that is under some hypothesis is to be found. This hypothesis states that the number of servers that is equal to 2, when the job arrival is in the Poisson process and that the task are in exponential service time distribution in general. The great scientist Nelson and Tantawi proposed that an approximation in the case where all the number of servers is much greater or equal to that of 2 and a homogeneous and exponential servers. After which, a more general case that is presented is where the arrival and service process are general in nature. Particle Swarm Optimization (PSQ, Interactive Evolutionary Computation(IEC),) and Differential evolution (DE) are the major 3 evolutionary algorithm that are on focus in this paper. When IEC is the suitable algorithm for discrete optimization (DO), PSO and DE that offer the continuous optimization are more natural. In this paper we give an introduction to all the 3 similar type of EA techniques to highlight all the common procedures of computation. The most common one we have is the observations in the similarities and differences among the 3 algorithms that are based on various computational steps that are discussed here contrasting to their basic performances. Overall the summary of the literatures discussed is given on the location allocation, flexibility in job shop, multimode resource project that have scheduling road blocks and vehicle routing constraints. 4.1 Average RT Calculation The average RT calculation is a measure of the time that an Enterprise Server consumes in order to return the result that is correct and needed. The RT gets affected by numerous factors such as the quantity of user, bandwidth of network thats available at that point of time, average think time of the server and the basic request type submitted to the server. Here in this section, the RT refers to the average or mean RT. Each and every type of the request has own minimal RT. Even though, when during the evaluation or the testing of the system performance, RT is based on the analysis of average RT of all the requests that is sent to the server. More faster the RT of web service, the more requests/min are being processed overall. However, as the number of users on the system rises, the RT starts to rise proportionally, all though the number of request/min decreases. The below mentioned graph of the system performance of all the server indicates that after a point, the requests/min are inversely proportional to RT. The more sharper the downfall in the requests/min, the steeper the increase in RT. The below mentioned figure clearly point at peak load which is when there quests/min starts to fall. Before this point, RT calculations are not precisely done and was not necessary because they do not use the peak numbers in the formula. But from now on, this point in the graph, the admin is more precisely calculated RT by using maximum number of users and requests/min. The formula used above is calculated using the below method and notations. Tresponse, thats the RT(in seconds) at peak load: Tresponse = n/r Tthink No.of con-current users is denoted by n No. of requests/sec that the server receives is denoted by r The avg think time (in sec) is denoted by Tthink The think time is always included in the equation to get a precise and accurate RT result. If n is max, then the system supports at peak load is6,500/second. r is at peak load, then the system can process at peak load is 2,770/second. The avg think time, Tthink, is 5 sec/request. Therefore RT is calculated by the following formula: Tresponse = n/r Tthink = (5000/ 1000) 3 sec. = 5 3 sec. Thus, the RT is 2 seconds. Application Server performances critical factors are RT, along with throughput. Everything after the systems RT is being calculated at the peak load. 5. Proposed Methodology Optimal web service composition plan that is a composition plans of this road block is very large (nm), is proposed in our paper that presents an approach to find and improve GA that are presented, it quickly converges all the appropriate composition plan. The Tabu search that is being used for generating the neighbor plans and are simulated annealing the heuristic that is applied for accepting or rejecting the neighbor plan. In this phase, all the services thats located after the users requirement will be deleted. Thereby, the remaining services that fulfill the user request. Now among these services, a service with the higher score will be selected. We have proposed the Tabu search and the simulated annealing (SA) that is a constrained satisfaction based approach. Yet, the approach has a high possibility of not completing the local optimum because it is unable to work on more than 1 composition plan simultaneously. We presented an approach in which genetic algorithm is used to find the optimal composition plan. The SA method applies progressive updates to the further generation and the selection of chromosomes to increment the speed of the algorithm performance. Thus, Self-orchestration explains all the Interaction between and within the services that itself orchestrates, before doing anything it actually does the execution. One of the primary languages for the defining self choreographies is the Web Service Choreography Description Language. When this is used partial initialization of chromosomes to escape all the local optimums in general. After all, this proposed method will works on a test sample of composition plans, which is on the contrary to the Tabu method. The different composition approaches that describes the different composition models is provided, which are self-orchestration, self-choreography, self-coordination and part of the component. Self-Orchestration is a description of how the services that participate in the composition of interaction at the message level, including the various order in which iterations that possibly should be executed as well as the business logic. Fig 1: Values of All Web Services and Tasks 5.1 Proposed Design The following diagram shows the activity functions. By using the database it will show all the relevant content to the user. And it tells about the flow of activity of each object. Activity diagram is another important diagram to describe dynamic aspects of the system. Its basically a flow chart that represent the flow from one activity to next activity. In this case the following diagram consist of Server, User, database, checking various query and Sub query. Each actor will perform certain function to achieve the desired goal. First a user enters into a system by providing correct user name and password. After this we will be able to type the query. A use case diagram in its simplest form is a representation of a users interaction with the all the system and depicting the various specifications of a use case. This should be noted that the process of filtering all the web services consists of functional match making and non-functional matchmaking as well. In functional matchmaking, all the web services that have different functionalities from the client are filtered out fully and on the other hand, in non- functional matchmaking, the web services that dont have the appropriate quality are only eliminated. At this stage, the candidate web services for each task are selected. Now the details of the user are fetched into the web agent memory or a temporary storage allocation site. Further the web agents analysis the various web applications in order to finalize the optimal web servers and the resulting information are displayed with user comments and reviews. Fig 2: Flowchart The below diagram tells about the different sequence we are following to make a user to view his related content. In this diagram contain different object like User, database, Validate, relevant and web access. And it tells about the flow of sequence between the objects. A sequence diagram is a kind of interaction diagram that shows how processes operate with one another and in what order. It is a construct of a Message Sequence Chart. The user inputs the login details and connects through we access which are then linked to the time and review request. Now, web agent analysis the various requests from the web applications and provides the information regarding the time and review and gives the possible details to the user. Fig 3: Sequence Diagram In recent years, the application of web-based systems in institutions and government agencies is increasing. Introduction of web services is an effective approach in business structures to provide the required capabilities of service providers for services composition. Selecting the precise user service based on the users request is primarily based upon the service quality of the available web services. Several different methods have been suggested to solve the road block of web services composition based on qualitative characteristics. These methods can be divided into two types of exact methods and approximate methods. The first type is known as non-innovative methods which selects the best design from all available designs by examining and calculating the candidates routes and thus provide a more precise answer. In the second type or innovative methods, contrary to the first type, an ideal design that is close to the best and most accurate answer will be chosen. The below mentioned graph that actually compares the various web services that are available in that field and displays its performance based on RT and user reviews that are given. Fig 4: Resulting Graph Due to the importance of optimal composition of web services in recent years, a lot of works have been done in the field of each method. By studying various types of innovative algorithm, one can conclude that many road blocks still exist to solve in web services composition based on qualitative characteristics. For instance, each of these methods usually have local optimality road block alone or in genetic algorithm that are non complex and basic, the crossover type and the operation of mutation acts randomly and without any guidance, which leads to degeneration of the method. Therefore, efforts to improve efficiency such as using combined methods, operators like revolution operator or adding functions to improve were performed. These techniques are provided for better speed, faster convergence, and higher efficiency in large spaces. Based on the mentioned studies, there is no specific benchmark tool for evaluating the algorithm. Although some researchers used different simulation environments or different data to compare them with each other, the results show that different methods have different disadvantages and they do not have any specific standard. Skyline algorithm method and parallelism technique are used in this proposed method in order to provide the best composition with regard to the shortest RT in high scalability. Conclusion For the purpose of retaining their client all the web services first priority is maintaining Service Quality. This paper pays attention to the RTs of composite Web service that plays a very important role in attaining service quality in web services.. We propose a heuristic model for predicting RT of web service and thereby selecting an optimal web service at the runtime from the list of functionally similar web services. For the purpose of the probabilistic instances of Web Services. We have used Hidden Markov Model. Our model has been made with the assumption of Web Services that is deployed on a cluster of web servers and thereby sometime the delayer crash during WS invocation happens which is because the bad node in sever clustering responds to request of the user. By using HMM where ever needed we have predicted the probabilistic nature and predicted the behavior of these web servers and then selected the Web Services based on their optimal probabilistic value. An approach is proposed to solve the Service Quality Architecture aware Web Service selection road block. To avoid this problem, an SQA based algorithm is presented that will reveal all selection leading to the results thats very close to optimal, efficient solution. This process in arriving at the solution is also done at a rapid speed which is worth mentioning. 7. Reference SalehieTahvildari L. Selfadaptive software: Landscape research challenges.

Galileo Galilei :: essays research papers

Galileo was an Italian mathematician, astronomer, and physicist. He was born in Pisa, Italy on February 15, 1564. In the mid 1570’s, he and his family moved to Florence and he started his formal education in a local monastery. He was sent to the University of Pisa in 1581. While there, he studied medicine and the philosophy of Aristotle until 1585. During these years at the university, he realized that he never really had any interest in medicine but that he had a talent for math. It was in 1585 that he convinced his father to let him leave the university and come home to Florence. Back in Florence, he spent his time as a tutor and began to doubt the Aristotle’s philosophy. In 1589, he was made professor of mathematics at the University of Pisa where he attended school. His position also required him to teach astronomy based on Ptolemy’s theory that all planets and the sun revolved around the earth. In 1592, he left the University of Pisa and went to the University of Padua to become professor of mathematics. During his time there, he constructed a clumsy thermometer which would have work if he had taken into consideration atmospheric pressure but it still has a significance in history as being one of the first measuring instruments in science. He taught he for 18 years and during that time, became convinced that there was truth in the theory of Nicolaus Copernicus a Polish astronomer who believed that all planets including earth revolved around the sun. While still at Padua, in 1609, he built the first astronomical telescope. When he used it to look at the sky, he easily found that most of Aristotle’s and Ptolemy’s theories were wrong. His most important discovery was when he discovered the four moons of Jupiter in 1610. Later that year Cosimo de Medici, Grand Duke of Tuscany, named Galileo his personal mathematician. This brought him back to Florence once again here he continued his studies in astronomy. Galileo also studied motion, especially that of freely falling objects. While watching swinging lamps in church one day, he noticed that it takes the same time between swings no matter how big or small the arc is. This observation led to his invention of the pendulum clock. He also discovered, before Newton, that two objects of different weights fell at the same speed.

Then started sharing my idea with my best friend, Stalin Gomes, who is currently studying at Bridgeport University in Connecticut and is also a under Of this company. He also shared a similar idea and we started working towards building our company in 2010. Then we named it â€Å"Athletic Footwear†. Our company's USPS is â€Å"The best you can have†. We are committed to provide our customers with varieties of top quality footwear. We are working with all the top athletic footwear brands like Nikkei, Aids, Rebook, Puma, New Balance, Gender Armor, Acacias, Sketchers, Vans and Umbra to bring all the new gears to our customers.Our company's marketing targets are runners, athletics, sneaker lovers and others. Our company's top priority ND goal is to provide the best customer service possible and going global. We want to run our business successfully and also want to go international. To reach our goal we need a very successful website and to make it; we need storefront softw are that offers us similar options and services we are looking for. In the article, Starting an online store made easy and ‘really sexy': E- commerce TTY McMahon and DOD Jones talk about the future of e-commerce.They wrote, â€Å"A whole new era of e-commerce is emerging – one where just about anyone can create high-end, custom branded online stores for next to thing. This is being made possible by a crop of emerging online e- commerce platforms backed by venture capital† (McMahon & Jones 2011). These days it's very tricky to find the right storefront software as there are so many storefront software offering different features like hosting, design, pricing and payment options, marketing tools, reports etc.There are also many fake web builders which might be harmful for businesses. The purpose of my research is to find the right storefront software for building a website for our business. The research that I have completed describes the important features that we need to consider when choosing storefront software. Below I have detailed each key features required for building a perfect website for my business. Also, I have selected three storefront software and compared their key features. At the end I have chosen the best one for my business.IMPORTANT STOREFRONT FEATURES FOR BUILDING A WEBSITE There are a lot of different storefront software companies these days offering different options and services. The most important thing to keep in mind when choosing a storefront software is our business needs, like it loudest make sense to use a smaller web hosting if we are building a huge website that requires multiple servers, it wouldn't make sense to pay for a lot of storage and features that we are not going to use if we are launching a small blob. I have decided to compare key features between three storefront software. They are Spiffy, Evolution and Precision Web Hosting.The important features that I have chosen to write about are unlimited w eb hosting, customizable web design, 24/ 7 customer service & security, shopping cart & payment options, product management, marketing & SEE, bile commerce and social media connectivity. Kari Fabian writes, â€Å"This type of application should help you design your website, upload and manage your inventory, connect to a shopping cart, and provide secure payment options to your customers† (commerce Software Review 2014). UNLIMITED WEB HOSTING Unlimited web hosting is the most important feature for building a website.I Want to expand my business in domestic level and also internationally, so it's very important for me to choose storefront software that offers unlimited web hosting. Spiffy and Evolution both offers unlimited be hosting but precision web offers very limited web hosting. In the article, Spiffy; The brains behind the online business the author writes, â€Å"Spiffy takes care of coding storage, backup servers, security and payment administration, in return for a su bscription fee and, with basic plans, a fee on each transaction† (Canadian Business 2011).Spiffy offers Content Delivery Network (CDC) which is large network of servers placed across the world to ensure that customers can load any website store quickly, no matter where they are. According to the article, For busy Evolution, e-business is good, Lori Hopkins talks about the features of Evolution. He writes, ‘Evolution helps businesses build their websites, update product information, offer online coupons, handle credit card transactions and track inventory, all in one place.Its social shopping feature lets customers add e-commerce stores to their Faceable and Namespace fan pages† (Hopkins 2010). Evolution also offers CDC, powered by Zamia, consists of tens of thousands of servers across the globe, allowing shoppers to access any site at lightning speed. Precision Web Hosting doesn't have servers all around the web, shoppers can't have access o all sites and also some loads slowly. That is a clear negative side of Precision Web Hosting as I want to expand my business globally. Ant my customers to access my website from any part of the world at lightning speed. All three storefront software also offer mobile common:e feature which lets users pull up smart phone ready storefronts. Evolution and Spiffy come with multiple hosted email accounts to help business owners communicate with customers. These web-based accounts allow owners to access their messages any†here they have an internet connection. On the there hand Precision Web Hosting comes with very few hosted email accounts to help business owners communicate with customers.I want to communicate with my customers so that I can let them know about new merchandise and sales, so think Evolution and Spiffy are in a better position in this case than Precision Web Hosting. CUSTOMIZABLE WEB DESIGN Choosing storefront software that offers customizable web design is also very important for a build ing a perfect website. In this feature we can customize our web page just as we want it or choose from different readmes templates to make it user friendly and website attractive.Spiffy offers â€Å"Spiffy Theme Store† which hosts a collection of over 1 00 premium and free commerce templates. The Theme Store includes professional looking templates for cloth ins & fashion, jewelry, electronics, art & photography, and other types of commerce sites. According to spiffy, many of the commerce templates found in the Spiffy Theme Store have been created by world-renown designers including happy cog, clearest and pixel union.On the other hand, Evolution offers dozens of free, ready-to-use templates by which we can make our website shine in less than sixty seconds y choosing from any of our high-quality commerce templates. With a wide variety of free templates to choose from, we will have a stylishly professional site that's sure to impress our customers. They also offer custom design and branding services to make businesses look unique. Precision Web Hosting also offers some similar services but a bit limited. They don't have options to design larger websites.They have limited ready to use templates and customizing options. I want to expand my business and also go international and for that I need storefront software, which is going to offer me to expand thou charging me more. Based on this information I think Spiffy and Evolution have better web customizing options then precision Web Hosting. 24/7 CUSTOMER SERVICE & SECURITY One very important feature to look at when selecting storefront software is 24/7 customer service and security from the storefront software company to protect the website and also function properly.Security is very important these days. Especially with increased threats of online fraud and identify theft. In the article, Evolution; Evolution announces credit card fraud protection service for online store owners the writer wrote, † In 2009, the umber of personal records that hackers exposed – data like Social Security numbers, medical records and credit card information tied to an individual – exceeded 220 million records, compared with 35 million in 2008†³ (Information technology business 2010). Evolution, spiffy and Precision Web Hosting offers secure and flexible commerce hosting.They offer PC/Clips-certified securities which are dedicated to keep our site's most sensitive sales and customer data safe from harmful activities. But Precision Web Hosting doesn't have 24/7 customer service. As Precision Web Hosting doesn't have 24/7 customer service, think it's not perfect for my business because I want my customers to get 24/7 customer service so that they are ready to do business with my company over and over again. SHOPPING CART & PAYMENT OPTIONS Another very important feature we need to consider when choosing storefront software is shopping cart.Evolution, Spiffy and Precision Web Hosting a ll accept credit cards. With Spiffy Payments, set up is instant, so we can accept Visa, Mastered and American Express the minute we launch our shop. Spiffy offers a low credit card rate, and no hidden fee. Evolution offers legible payment options. We can accept a variety of payment options including credit cards, Papal, Google payments and international currencies. Precision Web Hosting also offers different payment options like credit cards and Papal. Evolution, Spiffy and Precision Web Hosting all offer flexible and simple shipping options.Spiffy has shipping rates that can be set up in a number of different ways, including fixed-price, tiered, weight-based and location-based rates. Also, unlimited plan users can receive automatic shipping rates from major shipping carriers like LASS, USPS and Fed. While Evolution and Precision Web Hosting also has similar features but Spiffy has better product management and product tracking options. So, Spiffy is the best option to setup a shopp ing cart for our business website. PRODUCT MANAGEMENT Products make up the business of commerce.A great range of products keeps customers coming back for more. But adding thousands of products is not an easy task and is often vulnerable to errors. Also delivering and keeping track of the product is also a very important task. Spiffy have Track product inventory option through which they can help us avoid selling rodents that have run out of stock, or let us know when we need to order or make more of our product. Evolution has mass import service which can do exceedingly fast product setup and we can relax as their skilled data feed managers guarantee us error free product updates.While Precision Web has a very limited product management service with no product tracking options. As I am going to expand my business in the feature I will have more products and to track them need a storefront software that has good product management service. So, think Precision Web is not a good option for my business. MARKETING & SEE Marketing and SEE is another very important feature that we need to consider when choosing a effective storefront software for our business. SEE stands for search engine optimization.Spiffy, Evolution both offers advanced SEE built right into our store, we can earn higher organic rankings in Google, Bingo and other search engines. Also, they automatically help to earn rich snippet displays like Star ratings, pricing and stock Status in organic search results. Evolution also offers their customers to sell their products on Amazon and eBay. On the other hand, Precision Web also offers similar eaters like Spiffy and Evolution but are limited. They don't options for selling in Amazon and eBay.Spiffy, Evolution and Precision web all offers email marketing options which helps customers to know about all the latest updates and discounts of the business. I am looking for the best marketing and SEE featured software and I think Spiffy and Evolution are very good options to choose from. MOBILE COMMERCE These days almost 30% of the commerce sales are made through a mobile device. Spiffy plan includes a free, built-in mobile commerce shopping cart. This means our customers can browse and buy from our store hill on the go, using any mobile phone from anywhere.Also, we can manage our store on the go and choose from beautiful mobile responsive themes. Evolution also helps shoppers buy from businesses anytime, an)Where by delivering a completely mobile optimized experience, from browsing all the way to checkout. Instead of making shoppers fumble through the site with their thumbs, site will be fully compatible with any smart phone or tablet device. In Precision web shopping cart automatically re-sizes the Shop template to fit mobile Screen resolutions but doesn't have beautiful mobile themes to choose from. So, I think Precision Web is not a good choice for my business.

Adult Education is very important Essay

The problem in India is that we have adopted democracy without preparing the ground for it by educating population. But even now it is not too late if the programme of mass Adult educa ¬tion, or Social education is undertaken in right earnest as a mass movement. No doubt the provision of universal, compulsory and free primary education is the only solution to the problem of illiteracy. But the country cannot afford to leave out a whole mass of adults and grown-ups of our society from the benefits of the literacy-drive. Apart from the political justification to the problem, Adult education is needed because it is a powerful auxiliary and an essential incentive to primary education. No programme of compulsory universal education can bear fruit without the active support and co-operation of adults. It is, therefore, imperative that educational facilities should be provided to adults. Adult education, as the term signifies, is the education of grown-up men and women who are above eighteen years. Bryson says, â€Å"Adult education includes all activities with an educational purpose, carried on by people, in the ordinary business of life who use only part of their energy to acquire intellectual equipment. † Ernst Baker says, â€Å"Adult education is given on a part-time basis and, therefore, given concurrently with work and the earning of a living. † Maulana Azad re-oriented the concept of Adult education for preparing every citizen to play his part effectively in a democratic social order. So he renamed Adult education as ‘Social Education’. In our country, adult education is imparted tinder two aspects: (1) Adult Literacy i. e. education for those adults who never had schooling before; and, (2) Continuation education i. e. education for those adults who had some schooling before. Agencies of Social (Adult) education include all the bodies, organizations or institutions which ‘deliver the goods’ which contact the ‘consumers’ of social education and satisfy their needs. They may be categorized as under: (a) Teachers, Government servants, NSS and other volunteers, social education workers etc. b) Regular educational institutions like schools, colleges, rural colleges, community centres, agriculture extension groups, worker’s educational associations and voluntary organiza ¬tions. (c) Informal educational devices like forums, study circles, group discussions, listening groups, camps. (d) Recreational, educational bodies like theatres, cinemas, clubs, societies, fairs, melas, nautanki etc. (e) Institutions whose primary aim is not education, such as eligious bodies, the Army, Parents Associations, Co-operative Societies and other Government Departments. The scope of Adult education is very comprehensive. Social education covers all those topics that are not touched by education in general at school. Topics like religion, politics and family planning can now be discussed with adults who have a mature under ¬standing. Moreover, it aims at givi ng a new orientation to the outlook of adults to suit the dynamic world. Then, the growth grooves of each individual are different from those of others. Social education harmonizes differences in growth and it also provides an opportunity for growth to those who have not been able to grow properly or completely earlier. About the need and importance of Social (Adult) education Swami Vivekananda remarked : â€Å"So long as the millions live in hunger and ignorance, I hold every man a traitor, who having been educated at their expense, pays not the heed to them. Our great natural sin is the neglect of the masses and that is the cause of our downfall. No amount of politics would be of any avail until the mas ¬ses are well educated, well fed and well cared for. National development and reconstruction is closely allied to Adult Education. If democracy is to survive, we must educate the masses for social education is the new hope for illiterate masses. Social education is heeded to widen the intellectual and political horizon of the illiterate adults. It is also needed to sharpen the aesthetic sensibility of the adults and to set the cultural tone of the community. Moreover, social educa ¬tion is needed in order to guide in spending their leisure in healthful recreations and useful activities. Lastly, illiteracy and ignorance is a sin; an illiterate adult is a burden on society. Adult education emancipates people from the tyranny of illiteracy. The objects, or purposes, or functions of social education may be stated generally or pragmatically. The philosophically oriented functions of Adult education are clearing concepts of reality of universe and life, reconciling the old and the new approaches to life, balance and independent judgment, self-realisation, human relationship and citizenship training and economic efficiency. According to the second approach which is more pragmatic and practical education has to perform two-fold purposes to the indivi-dual and to the society. From the individual’s point of view social education fulfils various purposes remedial, vocational, health, recreational, self-development and social skills. From the social and national point of view the purposes of social education are social cohesion, national efficiency and development of national resources. On the practical plane, however, there are some difficulties that confront a Social education planner or worker. Some of the main difficulties and problems are : isolation of adult education in education, accommodating difficulties, age structure of the adults, the family circumstances and background of learners, occupational grouping, cultural background, socio-economic background, geo ¬graphical location of the social education centre, level of the social education worker teacher, lack of proper knowledge of adult psy ¬chology, paucity of leisure lack of equipment, lack of motivation, fatigue of adults and their constitutional and temperamental lethargy, lack of proper publicity, hostility from certain vested interests, poor supervision of centres and half-hearted implement ¬ation. The difficulties have to be overcome either by cleverness, or by fact or by compromise, or may be, by intentional avoidance. Only then we can hope to spread Adult Education. The purpose of all good teaching is to produce changes in human behavior. All adult education teacher must adopt a positive approach; he should help the adults learn quickly and effectively and willing by using any of the three prevalent methods – the Teacher Dominated methods, the Learner Dominated Method or the Co-operative Method. He may make use of any or all the seven types of aids given in the Govern ¬ment of India Handbook on Social Education viz, Spoken words, spoken words reproduced through radio or recording, written words, chart, graphs and maps, objects produced or reproduced as models, demonstrations, pageants, dramas, television and other objects represented as pictures, pictures reproduced by episcopate-slides etc. actual objects, field trips and specially arranged exhibitions, museums or films shows. Gandhiji’s idea of social service for college students during the vacation and, later on full time basis will prove invaluable in this regard. Young men and women taking up Adult education as a drive should be fired with a missionary zeal to eradicate illiteracy and ignorance from our country. The slogan should be â€Å"Each one, teach one. † Happily, greater emphasis has been laid on Adult Education in the Seventh Five-Year Plan. The tenth point in Prime Minister Rajiv Gandhi’s 20-point Programme-‘Expansion of Education’-also makes special mention of stimulating Adult literacy. Sizeable funds have been allocated and separate staff, including the block and Aanganwari people has been deployed to foster Adult education. Adult education officers have been appointed in each college and they supervise the running of adult schools by student volunteers. The programme of Adult education has to be undertaken on war-footing. adult education is very important . adults must know the basic things of life. adult education is needed because it is an essential part of primary education. some people in their early age did not get chance to education because of some reasons but if they are old they can get education and discover their live in a new way. people who are not making effort for the success cant succeed in their lives . we can get education in any age . education helps us in many ways. such knowledge is necessary for every person living in a democratic country. education is a important part of our life. education means knowledge and it is very important for us. in old times people do not send their girls to schools for education but now people want that there childern should be educated. if we are not educated we have to depend on others but if we are educated we do not have to depend on others. educated person can differentiate between good or bad. education increase our knowledge
