Question: Talk about the Case Study of Gillette Company. Answer: This paper plans to examine the Gillette Company which propelled the primary sharp edge framework in 1998. The Company grasped innovation and it acquainted the five-sharp edge framework with exceed its rivals (Nye, 2016). Be that as it may, the three-sharp edge framework was the huge component of the Gillette Company. Additionally, the three-cutting edge framework was acquainted with limit the disturbance which was brought about by the three-sharp edge framework when shaving. Along these lines, the Gillette has its advantages and disadvantages in the showcasing procedures as examined in this paper. In any case the geniuses, The Gillette grasped another innovation to improve the structures in the market. Through the system of grasping new innovation Gillette would keep up its clients. The Gillette utilized the methodology for progress by propelling the five-sharp edge framework to diminish the disturbance caused to the clients when utilizing the item (Dhebar, 2016). The promoting plan for the Gillette turned out to be increasingly forceful when they propelled the new items. Along these lines, the Gillette made a high benefit and attempted to exceed its key rivals in the market. Then again, the Gillette has cons in the advertising methodologies as illustrated in this paper. Because of the new innovation, the Company was obliged to retrain the staff for them to comprehend the innovation (Barrow Stowers, 2013). Simultaneously the Gillette limited the dedication for the clients consequently the piece of the pie declined. Additionally, the forceful showcasing rollout methodology made the Gillette acquire costs in publicizing the items. Likewise, the Gillette got analysis because of the crusades held when promoting the items (Stowell, Stowell,Grogan Grogan, 2017).

Stages of Personality Development

Acquaintance Personality alludes with the qualities of a person that sets him/her separated from others when exposed to fluctuating conditions. The improvement of character is because of the association between an individual’s hereditary arrangement and the encompassing. Character improvement starts even before birth and is affected by numerous outer factors.Advertising We will compose a custom research paper test on Stages of Personality Development explicitly for you for just $16.05 $11/page Learn More Many speculations have been designed to clarify the idea of character advancement. This conversation investigates the phases of character improvement created by Sigmund Freud and Erik Erikson. The psychoanalytic hypothesis was created by Sigmund Freud and managed the passionate advancement from a sexual viewpoint. This hypothesis was later altered by Erik Erikson who concentrated on the job of social cooperations in character improvement. Sigmund Freud’s Psychosexual Th eory According to Sigmund Freud’s hypothesis, a creating youngster has a specific â€Å"erogenous zones† like the butt, mouth and private parts that are delicate at each stage. In this manner, a youngster centers around what invigorates his â€Å"erogenous zones† at each stage. The requirements of a kid at each stage should be met, else he/she will wind up stalling out in that stage and this will influence him in adulthood. Freud thought of five phases of advancement which incorporate the oral, butt-centric, phallic, idleness, and genital stages (Engler, 2008). The oral stage begins when a youngster is conceived. This stage goes on for around one and half years. At this stage, the mouth is the central matter of center for the kid and the youngster invests the majority of the energy sucking and attempting to place everything in the mouth. At this stage, the sense of self and superego are not yet completely created and, consequently, the youngster utilizes the id. With time, the child understands that fulfillment of its needs probably won't happen quickly and, in this manner, he/she should act with a particular goal in mind so as to speed it up. For example, a child cries when he/she needs the should be fulfilled. At the point when an infant is weaned, he/she encounters a feeling of misfortune and the infant understands that he/she should not generally get what he/she needs. A kid whose requests are not met at this stage builds up a character of mockery, jealousy, negativity, and doubt. To an extreme or too minimal oral fulfillment has a negative effect. An individual who stalls out in this stage may create propensities like gnawing nails and biting things like pens as a grown-up. Somebody who doesn't get enough oral fulfillment at this stage may likewise create propensities for eating and drinking exorbitantly. Be that as it may, a kid whose necessities are met at this stage winds up being hopeful and appreciates the general condition (Engl er, 2008). The butt-centric stage starts when the youngster is around one and half years; when he/she begins getting prepared on the best way to utilize the latrine. At this stage, the child’s center is around removing body squanders. A kid may pick either to remove or hold the waste. The manner by which the guardians handle this contention decides its resolution.Advertising Looking for research paper on brain research? How about we check whether we can support you! Get your first paper with 15% OFF Learn More This emergency gets settled when the kid figures out how to conform to the requests of the guardians and the guardians handle the youngster sensibly. In this manner, with time the kid will comprehend the significance of being methodical and clean, and will, subsequently, wind up being a grown-up with poise. On the off chance that the guardians are extremely unforgiving when preparing the kid to utilize the can, the kid may decide to consent and build up a character of d eliberateness. Be that as it may, a kid who will not consent to the requests of the guardians winds up being untidy in future. A youngster who appreciates discharging flippantly will wind up being imprudent, careless, untidy, resistant, and scattered. Then again, a youngster who appreciates dragging out the maintenance of body squanders winds up being systematic, stingy, difficult, exact, and flawless. This stage goes on for around two years (Larsen and Buss, 2009). Next is the phallic stage where the child’s consideration is on the genital zone. The kids become mindful of the distinctions in their bodies and that of other offspring of the other gender. At this stage the youngster is fixated on the parent of the other gender and wants to dispose of the other one. A male youngster will want to have the mother yet considers his to be as a prevention. He begins getting desirous of the dad who he sees as his opponent in the opposition for the mother’s love. Notwithstanding , the kid is worried about the possibility that that the dad may emasculate him. At the point when the kid understands that he can't have the mother, he attempts to resemble his dad with the goal that he can win her. Thusly, he attempts to get the attributes of his dad. Hence, he learns his male sexual job, and this denotes the goals of the emergency. Then again, the female kid understands that she doesn't have a penis and starts aching to have one. She reprimands her mom for her absence of a penis and creates â€Å"penis envy†. She feels that she can't claim the mother since she doesn't have a penis. At the point when she understands that she can't get the mother, she gets pulled in to the dad. The young lady learns her sexual job by attempting to become like the mother in order to have the dad. In this manner, the contention is settled. Inability to determine this contention may prompt ladies having low confidence, a craving to demonstrate that they are better than men or c reating propensities for playing with men. For the men, inability to beat this stage prompts them having high goals and pomposity. Inability to determine the contentions in this stage and relate to the parent of a similar sex prompts foolishness, pride, dread of close love, and conditions like homosexuality (Larsen and Buss, 2009). The following stage is the idleness time frame in which the child’s sexual wants stay inert. At this stage, kids center around different exercises like games, tutoring, and making fellowships of a similar sex. This stage happens not long before pubescence. Inability to conquer the contentions in the phallic stage may influence a person in this stage and forestall him/her from participating in the normal exercises (Larsen and Buss, 2009).Advertising We will compose a custom research project test on Stages of Personality Development explicitly for you for just $16.05 $11/page Learn More The following stage is the genital stage. At this stage, a child ’s consideration moves back to the private parts and he/she begins making fellowships with individuals from the other gender. At this stage, people attempt to disengage themselves from guardians and manage the contentions that were not settled in the previous stages. A kid who settled all the contentions in the phallic stage will have sound and appropriate associations with the individuals from the other gender. Nonetheless, a kid who didn't beat the contentions at that stage will cut off up having upset associations with the other gender (Larsen and Buss, 2009). Sigmund Freud’s hypothesis has a few shortcomings. Initially, character can't be grown distinctly based on sexuality. Erik Erikson likewise doesn't concede to the idea of putting together character improvement with respect to sexual drive alone. Additionally, the phases of improvement are not upheld by any logical information however on contextual analyses. As opposed to Freud’s hypothesis that an indiv idual can't have the self image and superego since the beginning, contemplates show that these elements are clear in kids sooner than at the ages he recommended (Ewen, 1998). Erik Erikson’s Psychosocial Theory Erikson additionally accepts that character advancement happens in stages. Be that as it may, he doesn't concur with Sigmund Freud’s hypothesis of psychosexual stages. He accepts that character improvement happens because of social cooperation with nature. Through association with the earth, people build up an inner self. At each phase of improvement, an individual is worried about getting skillful. On the off chance that one figures out how to experience a phase effectively, their personality will be helped and they will build up a feeling of skill. Nonetheless, inability to deal with the stage appropriately will bring about a sentiment of inadequacy. At each stage, an individual experiences a contention that can either assemble or wreck their character (Engler, 2008). The primary phase of character advancement is that of trust or doubt and happens since a kid is brought into the world up to when he/she accomplishes the age of one year. At this stage the kid is vulnerable and relies completely upon others to deal with him/her. The baby will create sentiments of either trust or doubt contingent upon the consideration that he/she gets from the guardians. On the off chance that the individuals dealing with the youngster can proficiently deal with the kid, he/she will create trust and will consistently have a sense of safety and safe. Be that as it may, if the guardians of the youngster show dismissal and disregard to the kid, he/she will create doubt and will have sentiments of frailty. This kid may create wretchedness as a kid and this may go on even in adulthood (Larsen and Buss, 2009).Advertising Searching for research paper on brain research?

Get your first paper with 15% OFF Find out More The following stage is the point at which the kids create as sense to control the elements of the body and a feeling of self-sufficiency. This happens between the ages of one and three. Youngsters start to settle on decisions between food, garments and toys. During this stage, a kid can either build up a character of self-sufficiency or that of uncertainty or disgrace. A youngster who practices self-rule is continually investigating the general condition and attempting to make new disclosures on his/her own. A kid who creates sentiments of uncertainty or disgrace is less certain and is less keen on investigating new environmental factors.

The Craziest of Weeks

The Craziest of Weeks Hello homies. Its been a while, right? I feel like I start off every blog entry like that. I should work on it. Anyway, I would like to formally welcome you admitted and delightful goobers to the Institute. Four years ago my Pi Day was filled with lots of screaming of excited expletives (that I cant post on the blogs) with my dad. I earnestly hope that you celebrated accordingly, and similarly. Flash forward four years and youll see that my 2013 Pi Day was equally exciting, though in a totally different way. Actually, I had a week that was a little nuts. Shall we recap? Lets do it! It all started a couple weeks ago, when I had an email exchange with my academic advisor that went a little something like this: Advisor: Yo dawg do you want to go to London next week? Me:  (Calmly) UmmmmOKAY.* *Note: Liberally adapted from original discussion. Figure 1. My internal reaction to my advisor. Wednesday night: Travel agent books my airline tickets and hotel confirmation for my trip thats supposed to start in less than 48 hours. Figure 2. MITs travel agent. Thursday morning: Spend the morning with my 20.380 group working on our design pitch. Im currently taking the Course 20 (Biological Engineering) senior capstone class, which is essentially a course on How To Make Stuff And Not Have It Suck as it is related to microbes. We spend a semester together with our team and develop a novel product to tackle antibiotic resistance, cancer, and/or manufacturing/synthetic biology while considering experimental design, testing, business models, patent issues, cost analysis, and all the fun things that you sort of forget about when youre taking regular classes. I frantically assemble some slides to illustrate the motivation behind our teams product for the upcoming design pitches. Figure 3. Making things work. Thursday afternoon: Swing by lab to finish up some experiments for my undergrad research project (UROP). I work for this guy on caged nanoparticle drug delivery. Then go to 21A.301 (Medical Anthropology of Disease and Health in Society) and watch a pretty intriguing documentary. Also, only at MIT would the entire class stick around voluntarily after a movie to discuss it, even though the professor isnt there. Figure 4. My UROP. Thursday evening: Go to MITSO (MIT Symphony Orchestra) rehearsal to prep for our upcoming Rite of Spring CD recording session and concert. I return home and feel like Im forgetting something. O RITE (get it?), IM LEAVING THE COUNTRY TOMORROW MORNING. Frantic packing ensues. Friday: I mosey on over to Logan Airport not-so-bright and early in the morning. I have no idea whos going on the trip from MIT, nor do I really know much about what Im supposed to do there. I arrive in Heathrow Airport, and marginally expect my life to play out like a scene from Love Actually, because all scenes in Heathrow Airport play out like this, right? No? Well, thats okay, because I got to ride the Heathrow Express from the airport to the heart of the city, and the Heathrow Express sure beats Bostons equivalent Silver Line. Figure 5. Maybe if we host the Olympics we can have nice things, too. Saturday: Wake up and meet up with a friend from high school who is studying abroad in London this semester. We galavant around the Natural History Museum and the Science Museum like typical American tourists (or about as typical as a Peruvian American and Korean American can get?), which involves being loud, running into things, and looking the wrong way before crossing the street. Admission to almost all of Londons museums is free. And as we all know, free is my favorite number. Figure 6. Seb and me hanging out with Darwin at the Natural History Museum of London. Sunday: My liberal arts side geeks out as I visit the National Gallery of London to see works by Saurat, Van Gogh, Michelangelo, Monet, Manet, Cezanne, Da Vinci, Raphael, Vermeer, and a new favorite JMW Turner. Then I book it to Tate Modern where high school Elizabeth sees works from her heros, Man Ray, Mark Rothko, Kandinsky, Picasso, Matisse, and Magritte. Then I get massive LOLz trying to locate a Roman Catholic church in the heart of London. Figure 7. Not my hotel, although it was right next door to it. Monday: The real reason why Im in London! I put on big girl clothes (wut iz this business attire you speak of??) and walk over to the Royal Academy of Engineering, where folks from RAE have organized a Microsoft-sponsored student day gathering around 60 engineering students from around the world to tackle one of 6 global challenges. After splitting up into groups consisting of undergraduate and graduate students from all over the U.S. and U.K., we hear from industry professionals everyone from the guy who designed the 2012 Olympics velodrome to an academia spin-out company founder who teach us principles about design and presentation. On my team are students from London, Chicago, Ohio, and even an MIT alum who also worked in the Langer lab! We get roughly 5 hours to come up with a design pitch of a solution to one of the global challenges, and then have to present it to a team of mock angel investors who will select a team to present to the RAE, National Academy of Engineering, and Chinese Academy of Engineering-sponsored 400-person conference on Wednesday. Basically, we had about 5 hours to solve the worlds problems. NBD. Well our team ends up not doing too shabby, as we win the thing, despite us literally coming up with an idea 30 minutes before the pitches were supposed to happen and as I literally doodled a Powerpoint presentation together minutes before we went up to present. Where is that Beyonce gif when you need it? Figure 8. Our team tackling the challenge of health care accessibility. Many thanks to the Global Grand Challenges Summit Staff for the photo! Monday night: A hilarious dinner with rowdy Americans, Brits, an Italian, and a Cypriot. I wish I had photos now but youll have to hold on and trust me on this one. Meeting new people = the best. I met so many thoughtful folks from all over the world, from so many universities, all trying to make the world a better place. Never has it been more evident to me that it doesnt matter where you are so much as what you do. It was humbling and exciting and gave me a renewed sense of purpose, which was unexpected but something Im grateful for nonetheless. Figure 9. How I feel when I meet new people. Tuesday: The other real reason why I came to London The first ever Global Grand Challenges Summit begins, as roughly 400 engineers gather to discuss how to literally solve the worlds problems.  This day and the following merit their own blog post, so worry not there will be LOTS more on this, I promise! But in a nutshell, I heard speakers ranging from Craig Venter (who I have some serious beef with, which made for an interesting experience) to MITs own Bob Langer (oh hey!), Angela Belcher, Neil Gershenfeld, to fashion designers, to FIRSTs Dean Kamen. Quick highlights: When Jeffery Sachs totally called out policymakers for their total bull when it comes to stiffling necessary innovation and doing good in the world, and then when Shells Environment VP had to follow him on the panel. AMEN to J. Sachs. When Neil Gersenfeld was trying to describe MIT to the audience and he said, MIT is a place where strange people who dont fit in anywhere else go. When will.i.am of the Black Eyed Peas randomly showed up to the education panel and point-blank told the audience, Kids dont worship the people who are solving the worlds problems like they do athletes or movie stars, and its no ones fault but yours. I disagreed with some of the details, but agreed with the overall sentiment. When half the nerds at the conference didnt know who will.i.am was. Wednesday (Pi day): More conference! More speakers! More on this later! Our team presents to the conference and we even get some people e-mailing us about investing in the project. So, who knows where itll go? Figure 10. Two of our team members pitching the idea of Telehealth Express. Then I book it to the airport, where I BARELY make check-in thanks to a delayed flight. I pull out some papers I need to write and a manuscript I need to finish, but end up talking to the lady sitting next to me for hours. Turns out that shes from France, but flying to Boston from Vienna, and shes recently met one of my documentary professors from last year. The world is so small! We talk about Mozart, my research, her research (turns out she lectures at Harvard Medical School), and pastries. Like I said, meeting new people = the best. Figure 11. Go team! Many thanks to the GGCS team for the photo. Thursday: I wake up in a bit of a daze and join my 20.380 team early in the morning to rehearse our design pitch (ack so many pitches!) and in an hour, we deliver it to the class. More class in the afternoon, a quick dinner, and I head over to Kresge Auditorium to join MITSO as we begin our first day of recording Rite of Spring. Its the first time weve recorded a CD since Ive been in MITSO, so itll all pretty exciting. Figure 12. My crappy photo of MITSO getting ready to record. Friday: To be honest, I dont really remember what happens. But I do remember playing the MITSO concert to a sold-out Kresge. Figure 13. How I feel when Im playing Stravinsky. Saturday: Work work work to make up all the work I didnt do in London. Then I head over to WMBR to host my radio show (P.S. remember that one time I blogged about crossing off #12 on my senior bucket list? Well I loved hosting a radio show so much that I decided to apply to have my own, so now thats a thing.). Then more work! When the evening rolls around, I meet my friend, Steven, who has given me possibly the GREATEST BIRTHDAY PRESENT OF ALL TIME We end up having a hilarious conversation with a random Emerson College student on the #9 bus (again, meeting new people = the best), who ends up showing us the way to our destination Brighton Music Hall, where the Dropkick Murphys are about to play one of their annual St. Patricks Day/weekend concerts (which I get to witness because I have an awesome friend who knew what #5 on my senior buck list was). We squeeze in with a couple hundred diehard, Bostonian fans, and proceed to witness a most supreme show. So much noise. So much sweat. So many Bruins jerseys. So. Much. Fun. Also, can I just comment that punk musicians and fans are some of the most women-respecting and considerate people around? Really. And the guys in the band were incredibly nice, bringing people on stage at the end for Dropkick Karaoke, where they had fans pick songs to sing. I cannot think of a better way to ring in St. Patricks Day and my birthday. Figure 14. Is there anybody hooooommmmeee?? Sunday: For the first time, I actually go into Boston on St. Patricks Day, to meet up with a friend from middle school. I talk to some random people also trying to navigate their way to South Boston, but we end up giving up nagivating above ground because the parades have slowed the buses down. For once, Bostonians are friendly and awesome to talk to maybe St. Patricks Day has put everyone in a better mood? I proceed the next hour going in a circle because I accidentally get on the subway going the wrong direction, but eventually I DO make it over, find my friend, and toast to 22. The city is surprisingly civil and unrowdy, and I absolutely love seeing everyone dressed up in tacky amounts of green. I love it. Then its back to MIT where everyone seems to be wearing black (hahahaha) and where I finish up some work. Another study break ensues in the late evening as some of us head out to the Asgard, a nearby Irish pub, for one last hurrah before the week and see Tin Can Hooley, a local Irish band. And here I am now, almost a week later, still a little out of breath and still catching up on some stuff. Was it worth it? HECK. YES. Figure 15. How I feel now.

Abstract Selecting an appropriate career path is one of the most important decisions in an individual’s life span. People end up getting into a profession where they neither enjoy nor get out of it due to several reasons like financial situation, family pressure, single source of income, cost of education and availability of vast career opportunities. Thus, student may select a wrong career option and the consequences of this wrong decision could be job dissatisfaction. Don’t waste time! Our writers will create an original "Mining Patterns for Career path based on Innate Talents" essay for you Create order An ultimate motive behind this research is to identify the most suitable career path that fits personality and working environment resulting positive outcome such as job satisfaction by using an appropriate data mining technique and a validated Holland’s theory, which is one of the most popular models used for career personality tests. Apart from this, other three factors will be obtained. Thus, for finding the Intersection, four factors are going to be considered: their personality traits, their interests, market trends and pay scales. The proposed system would help students to select an appropriate career path based on their personality traits by matching their â€Å"three-letter code† with the employee’s code. I. INTRODUCTION In Today’s world Career recommendation to the college students is a herculean task. The awareness of Career among the students is very less. Some students don’t know their abilities. Some students choose the career because his/her friend has chosen the same or their guardian forces them to opt for a career without knowing the actual interests, strengths and abilities in a particular area. Some parents force to satisfy his dream which they have seen in their childhood. Thus, students suffer a whole life. So, to help students from such conditions people have started the career counselling organizations. They provide guidance regarding career but does not analyse the abilities of the students. So, they allow students to choose career on their own. Here same problems occur that students don’t know their actual interest, abilities and strengths. Thus, to overcome such situation this project aims at evaluating some patterns by applying data mining techniques on employee’s data that would help students to select an appropriate career path based on their personality traits, their interests, market trends and pay scales. II. RELATED WORK There are various websites and web applications over the internet which helps students to know their suitable career path. But most of those systems only used personality traits as the only factor to predict the career, which might result in an inconsistent answer. Similarly, there are few sites that suggest career based on only the interests of the students. But the systems did not consider market trends and pay scales to increase the job satisfaction. None of the system has considered all the four factors namely personality traits, interests, market trends and pay scales. Also, the suggestion provided by the system for course is much generalized. For example, the results of few systems were a group of courses like data analyst, accountant, law etc. Thus, if a student gets such a recommendation then he/she might again get confused as the above specified course belong to different streams. The paper by [1] Elakia, Gayathri, Aarthi and Naren J suggest suitable career options for high school students based on every student’s interests, skills, likes, hobbies etc. and they have considered â€Å"discipline† as an important factor to continue higher studies and pursue one’s career. hence the chance of a student to get violent in future is predicted. The main objective of the paper by [2] Avinsh Kumar, Akshat Gawankar, Kunal Borge Mr Nilesh M Patil is to provide an overview on the data mining algorithm that are been used to predict student profile and personality. They have created online survey system that will help student to make career choices and understand their personality traits. Another paper by [3] Gentaneh Berie Tarekegn Dr. Vuda Sreenivasarao have attempted to use data mining techniques to analyse student’s entrance exam result to predict student’s placement into departments. The paper by [4] Nikita Gorad, Ishani Zalte, Aishwarya Nandi Deepali Nayak recommends the student, a career option based on their personality trait, interest and their capacity to take up the course. According to the paper by [5] Lokesh S. Katore, Bhakti S. Ratnaparkhi Dr. Jayant S. Umale they have developed the career recommendation system which will recommend the career to the students based on their personality traits. The paper by [6] Ms. Roshani Ade Dr. P.R. Deshmukh suggested incremental ensemble of classifiers in which the hypothesis from number of classifiers were experimented and by using ‘Majority voting rule’, the fin al result was determined. III. OVERVIEW The basic idea of this research is to acquire the data from the employees and to evaluate some patterns from that data. From that evaluated patterns certain career can be suggested to the students. For evaluating patterns from the employee’s data, four factors are going to be considered: their personality traits, their interests, market trends and pay scales. Figure 1: Four factors 1. Personality traits: Hollands six personality types are considered here as various personality traits. According to Holland’s theory of career choice most people are one of six personality types: Realistic Investigative Artistic Social Enterprising Conventional Thus, using these personality types, different careers will be classified. [7] Here, 42 questions are asked for evaluating personality traits. The â€Å"three-letter code† with the highest scores will be determined from these six personality types. Then after this â€Å"three-letter code† will be matched with some already defined professions and if there is a match between this profession and a code then it will return â€Å"Yes† in â€Å"P-E fit† field otherwise â€Å"No†. Thus, first factor named â€Å"P-E fit† will be evaluated. 2. Interest: Interest in this context means asking employees whether they are doing interest-based job or not. If â€Å"yes† then only we will consider their data for pattern evaluation and if â€Å"no† then we will simply ignore that entries because we aim to suggest the career on the basis of the employee’s data and if employee is not satisfied with his/her job then that is not the perfect match for him/her also, ultimately they are doing something in what they not even interested so, how can we suggest it to students? So, its mandatory that we verify the data which we are going to use for suggesting the career path to the students. Thus, second factor named â€Å"Interest based† will be evaluated. 3. Market trend: Top trending jobs from the market will be taken into consideration. The labour market is changing rapidly. No one can be sure of what will happen in the future, but some trends in the labour market do give clues about what is likely to happen. When making decisions about your education or career, it is important to understand these trends and to make good choices based on this information. [11] As of now, for this research purpose, its assumed that â€Å"Travel agent† is not a trending job as the internet has turned vacationers into their own travel agents. Websites, such as Kayak and Expedia, and Web applications, such as MakeMyTrip, Trivago, TripAdvisor enable travellers to book flights, cruises, and hotel rooms with ease. Hence, no travel agents are needed any more. So, if there is a travel agent in the responses then it will return â€Å"No† in â€Å"Trending job† field otherwise â€Å"Yes†. Thus, third factor named â€Å"Trending job † can be evaluated. 4. Pay scale: A pay scale (also known as a salary structure) is a system that determines how much an employee is to be paid as a wage or salary, based on one or more factors such as the employees level, rank or status within the employers organization, the length of time that the employee has been employed, and the difficulty of the specific work performed. [8] For evaluating fourth factor named â€Å"Pays well†, we have assumed that 10,000 should be the minimum salary for any employees working in any field, so if their salary is less than 10,000 then it will return â€Å"No† in â€Å"Pays well† field otherwise â€Å"Yes†. IV. IMPLEMENTATION Figure 2: Implementation steps Step 1. Data collection (using google form-spreadsheet): The first step of implementation was to collect data from employees working in different fields. For this purpose, an online survey was conducted using Google forms. The questions asked in the survey are based on personality traits (42), and two more questions for asking about their interest and income. This data has been collected from the employees working in various job sectors such as State Bank of India(Modasa), Union Bank(Gandhinagar), Travel Infoline(Ahmedabad), Institute for Photography Excellence(Ahmedabad), inifd(Gandhinagar), District court(Gandhinagar), Rajshree Studio(Idar), Torrent Pharmaceuticals Limited (Mehsana) and Nootan Vidyalaya(Kadi). As this is the google form, I shared the link with all my friends and family members and asked them to fill it and forward it in their groups. Figure 3: Google form sample Step 2. Downloaded as MS Excel: Responses was downloaded as MS Excel (.xlsx) Figure 4: Raw dataset Step 3. Pre-processing (in excel): Then data obtained from the survey had to pre-processed and consolidated into a common format as required by the system in MS Excel. Based on the answers given by employees, three-letter code for each individual was generated. For example, with a code of RIA you would most resemble the Realistic type, somewhat but less resemble the Investigative type, and somewhat but even less resemble the Artistic type. The types that are not in your code are the types you resemble least of all. Most people, and most jobs, are some combination of two or three of the Holland interest areas. [9] By using this data â€Å"P-E fit†, â€Å"Interest based†, â€Å"Trending job† and â€Å"Pays well† was determined and then after â€Å"Intersection† was calculated by considering all these four factors. If all the four factor’s values are â€Å"Yes† then â€Å"Intersection† field’s value will be â€Å"Yes† otherwise â€Å"No†. Thus, target attribute named â€Å"Intersection† will be evaluated. Figure 5: Pre-processed dataset Step 4. DM Tool (RStudio): RStudio is a data mining open source tool for applying data mining algorithms over the data collected from the users. It is an â€Å"Integrated development environment (IDE)† that helps you develop programs in R that means R is a â€Å"Programming language† while R studio is a â€Å"Platform† to use R. You can use R without using RStudio, but you cant use RStudio without using R, so R comes first. [10] Step 5. DM Algorithm: Data mining is all about extracting patterns from an organizations stored or warehoused data. These patterns can be used to gain insight into aspects of the organizations operations, and to predict outcomes for future situations as an aid to decision-making. [4] A. Decision tree algorithm: A decision tree is a structure that includes a root node, branches, and leaf nodes. Each internal node denotes a test on an attribute, each branch denotes the outcome of a test, and each leaf node holds a class label. The topmost node in the tree is the root node. [22] 1. ID3: In decision tree learning, ID3 (Iterative Dichotomiser 3) is an algorithm invented by Ross Quinlan, used to generate a decision tree from a dataset. ID3 is the precursor to the C4.5 algorithm, and is typically used in the machine learning and natural language processing domains.[12] 2. C4.5: C4.5 is an algorithm used to generate a decision tree developed by Ross Quinlan. C4.5 is an extension of Quinlans earlier ID3 algorithm. The decision trees generated by C4.5 can be used for classification, and for this reason, C4.5 is often referred to as a statistical classifier. Authors of the Weka machine learning software described the C4.5 algorithm as a landmark decision tree program that is probably the machine learning workhorse most widely used in practice to date. It became quite popular after ranking #1 in the Top 10 Algorithms in Data Mining pre-eminent paper published by Springer LNCS in 2008. Improvements from ID.3 algorithm: C4.5 made a number of improvements to ID3. Some of these are: Handling both continuous and discrete attributes In order to handle continuous attributes, C4.5 creates a threshold and then splits the list into those whose attribute value is above the threshold and those that are less than or equal to it. Handling training data with missing attribute values C4.5 allows attribute values to be marked as â€Å"?† for missing. Missing attribute values are simply not used in gain and entropy calculations. Handling attributes with differing costs. Pruning trees after creation C4.5 goes back through the tree once its been created and attempts to remove branches that do not help by replacing them with leaf nodes. [13] 3. C5.0: C5.0 is widely used as a decision tree method. It provides the set of rules which is easy to understand. C5.0 algorithm gives acknowledge on noise and missing data. Problem of over fitting and error pruning is solved by the C5.0 algorithm. In classification technique, the C5.0 classifier can anticipate which attributes are relevant and which are not relevant in classification. [4] Improvements in C5.0 algorithm: C5.0 offers a number of improvements on C4.5. Some of these are: Speed C5.0 is significantly faster than C4.5 Memory usage C5.0 is more memory efficient than C4.5 Smaller decision trees C5.0 gets similar results to C4.5 with considerably smaller decision trees. Support for boosting Boosting improves the trees and gives them more accuracy. Weighting C5.0 allows you to weight different cases and misclassification types. Winnowing a C5.0 option automatically winnows the attributes to remove those that may be unhelpful. [14] Boosted C5.0: Adaptive boosting involves making several models that â€Å"vote† how to classify an example. To do this you need to add the ‘trials’ parameter to the code. The ‘trial’ parameter sets the upper limit of the number of models R will iterate if necessary. [15] 4. CART: Classification and Regression Trees (CART) split attributes based on values that minimize a loss function, such as sum of squared errors. [16] Classification and regression trees (CART) are a non-parametric decision tree learning technique that produces either classification or regression trees, depending on whether the dependent variable is categorical or numeric, respectively. Decision trees are formed by a collection of rules based on variables in the modelling data set: Rules based on variables values are selected to get the best split to differentiate observations based on the dependent variable Once a rule is selected and splits a node into two, the same process is applied to each child node (i.e. it is a recursive procedure) Splitting stops when CART detects no further gain can be made, or some pre-set stopping rules are met. (Alternatively, the data are split as much as possible and then the tree is later pruned.) Each branch of the tree ends in a terminal node. Each observation falls into one and exactly one terminal node, and each terminal node is uniquely defined by a set of rules. [17] 5. Random Forest: Random forests or random decision forests are an ensemble learning method for classification, regression and other tasks, that operate by constructing a multitude of decision trees at training time and outputting the class that is the mode of the classes (classification) or mean prediction (regression) of the individual trees. Random decision forests correct for decision trees habit of overfitting to their training set. [18] Random Forest is variation on Bagging of decision trees by reducing the attributes available to making a tree at each decision point to a random sub-sample. This further increases the variance of the trees and more trees are required. [16] 6. This algorithm stands for â€Å"Conditional Inference Tree†. Statistics-based approach that uses non-parametric tests as splitting criteria, corrected for multiple testing to avoid overfitting. This approach results in unbiased predictor selection and does not require pruning. [19] Ctree is a non-parametric class of regression trees embedding tree-structured regression models into a well-defined theory of conditional inference procedures. It is applicable to all kinds of regression problems, including nominal, ordinal, numeric, censored as well as multivariate response variables and arbitrary measurement scales of the covariates. [20] B. Neural Network: An Artificial Neural Network, often just called a neural network, is a mathematical model inspired by biological neural networks. Neural networks are used to model complex relationships between inputs and outputs or to find patterns in data. [21] A neural network is a model characterized by an activation function, which is used by interconnected information processing units to transform input into output. A neural network has always been compared to human nervous system. Information in passed through interconnected units analogous to information passage through neurons in humans. The first layer of the neural network receives the raw input, processes it and passes the processed information to the hidden layers. The hidden layer passes the information to the last layer, which produces the output. The advantage of neural network is that it is adaptive in nature. It learns from the information provided, i.e. trains itself from the data, which has a known outcome and optimizes its weights for a better prediction in situations with unknown outcome. [23] C. Naà ¯ve Bayes: The Naive Bayesian classifier is based on Bayes’ theorem with the independence assumptions between predictors. A Naive Bayesian model is easy to build, with no complicated iterative parameter estimation which makes it particularly useful for very large datasets. Despite its simplicity, the Naive Bayesian classifier often does surprisingly well and is widely used because it often outperforms more sophisticated classification methods. [24] V. RESULTS OF IMPLEMENTATION The dataset was then used to derive the results, using the various packages available in R for generating decision tree. The C5.0 algorithm applied on the dataset had the accuracy of 100%. The output after plotting the decision tree is shown in Figure 6. This tree is generated by considering all the four factors namely personality traits, their interest, market trends and pay scales. Figure 6: decision tree with all the four factors We have also generated the various trees with considering one factor at a time while applying C5.0 algorithm on the dataset. The visualization of the decision trees with â€Å"Trending job†, â€Å"P-E fit†, â€Å"Interest based†, â€Å"Pays well† are â€Å"Figure 7†, â€Å"Figure 8†, â€Å"Figure 9†, â€Å"Figure 10† respectively. Figure 7: decision tree with â€Å"Trending job† Figure 8: decision tree with â€Å"P-E fit† Figure 9: decision tree with â€Å"Interest based† Figure 10: decision tree with â€Å"Pays well† From the following graph, we can get a clear idea of the comparison of the five methods. Figure 11: accuracy with various factors Thus, this graph shows that for selecting a career of a student all the four factors are important namely personality traits, their interest, market trends and pay scales. VII. CONCLUSION This work has discussed the Holland’s theory and various data mining techniques in relation to observations indicating that some students have difficulty in determining a suitable career. As this affects their performance, productivity and satisfaction, it is critically important to understand how to find a career that fits their personality. The results generated from the employee’s data can be useful for evaluating patterns in order to determine a suitable career path for the students based on the four factors namely personality traits, interests, market trends and pay scales.

Along with this present growth, the field of marketing financial services has also grown in size and scope with new entrants everyday. The relatively stable banking environment is being altered with innovation, opportunism, and government intervention. This era, marked by the government s luminous hand of deregulation (defined as the act of removing regulations or restrictions from a specific entity), has expanded consumer options to the extent that commercial banking must now become an aggressively competing member of the financial services industry. In this new era, important marketing areas such as regulation, environment, product,†¦show more content†¦In making decisions concerning a bank s strategy, the institution must take into account several initial areas that may formulate a restraint in implementation. They are the economic and cultural environment, the competitive banking atmosphere (extremely competitive), the marketing strategy to be implemented, and the pricing/promotion that goes into the marketing function. (McMahon, 1986). III. Environment The foundation of a successful bank marketing scheme lies with a strong understanding of the environment in which the institution is located. The most important environmental variables are those operating outside the bank, known as the external environment and those within the organization, known as the internal environment. (McMahon, 1986). The external environment includes components such as legislation, prime rate, competition in the market, local business practices, and technology. Most importantly, the external environment must look and examine the effect of the national and regional economy as it pertains to the marketing situation. First, bank managers need to examine certain forms of legislation, such as the government s present deregulation process. (Hodges and Tillman, 1968). Due to stiff pressure from customers and the business community alike, bank regulators, federal and state, are releasing their tight grip over the previously controlled industry.

Why is the coefficient for BEDROOMS a positive number? The selling price increa se when the number of rooms increases. Thus the relationship is positive. b. Which is the most statistically significant variable? What evidence shows this? Most statistically significant variable is one with least p value. Here most statistically significant variable is Square feet. c. Which is the least statistically significant variable? What evidence shows this? Least statistically significant variable is one with high p value. Here least statistically significant variable is bedrooms d. For a 0. 05 level of significance, should any variable be dropped from this model? Why or why not? The variable bed rooms can be dropped from the model as the p value is greater than 0. 05. e. Interpret the value of R squared? How does this value from the adjusted R squared? The R2 gives the model adequacy. Here R2 suggest that 72. 22% variability can e explained by the model. Adjusted R2 is a modification of R2 that adjusts for the number of explanatory terms in a model. Unlike R2, the adjusted R2 increases only if the new term improves the model more than would be expected by chance. f.

In what type of regression is it likely to occur? Regressions involving time series data . What is bad about autocorrelation in a regression? The standard error of the estimates will high. c. What method is used to determine if it exists? (Think of statistical test to be used) Durbin Watson Statistic is used determine auto correlation in a regression. d. If found in a regression how is it eliminated? Appropriate transformations can be adopted to eliminate auto correlation. Problem 8 Define Multicollinearity in the following terms: a) In what type of regression is it likely to occur? Multicollinearity occurs in multiple regressions when two or more independent variables are highly correlated. ) Why is multicollinearity in a regression a difficulty to be resolved? Multicollinearity in Regression Models is an unacceptably high level of intercorrelation among the independents, such that the effects of the independents cannot be separated. Under multicollinearity, estimates are unbiased but assessments of the relative strength of the explanatory variables and their joint effect are unreliable. c) How can multicollinearity be determined in a regression? Multicollinearity refers to excessive correlation of the predictor variables. When correlation is excessive (some use the rule of thumb of r 0. 90), tandard errors of the b and beta coefficients become large, making it difficult or impossible to assess the relative importance of the predictor variables. The measures Tolerance and VIF are commonly used to measure multicollinearity. Tolerance is 1 – R2 for the regression of that independent variable on all the other independents, ignoring the dependent. There will be as many tolerance coefficients as there are independents. The higher the inter-correlation of the independents, the more the tolerance wil l approach zero. As a rule of thumb, if tolerance is less than . 20, a problem with multicollinearity is indicated. When tolerance is close to 0 there is high multicollinearity of that variable with other independents and the b and beta coefficients will be unstable. The more the multicollinearity, the lower the tolerance, the more the standard error of the regression coefficients. d) If multicollinearity is found in a regression, how is it eliminated? Multicollinearity occurs because two (or more) variables are related – they measure essentially the same thing.
