How personality contribute to your career choices |
|
Answer» re many theories around which personality types suit specific job roles. One such theory is Holland’s Theory of Career Choice, which categorises people into six personality types. For example, there are the Realistic ‘Doers’; the carpenters, ELECTRICIANS and engineers, and the Investigative ‘Thinkers’ who are the biologists, mathematicians and computer programmers of the world.More advanced personality measures also provide insights into people’s work preferences. For example, many have explored how the MBTI personality types fit with certain job roles. However, these connections are sometimes oversimplified.Here, we take a look at the 'role elements' associated with each of the five factors in the Facet5 model.WillPeople with High Will are more likely to be SURE of their career direction. They’ll make a decision early and stick to it. They are driven by the ability to influence, and therefore it may come as no surprise that most lawyers are High Will. By contrast, people with Low Will are much more interested in what OTHERS think before making decisions.Work preferences of High Will individuals:Having control over people and situations to shape directionMaking decisions, particularly those that will make a genuine difference to performanceLeading people and taking chargeWork preferences of Low Will individuals:Shared responsibilities in a teamRoles which require research and finding out other people's points of viewsRoles which have a focus on building relationshipsEnergyHigh Energy individuals can be more prone to moving around different roles. They tend to only stay in a role until they feel they have explored it as far as they want, and then become attracted to something different, offering an opportunity for change and to learn new skills. Low Energy people are quite the opposite in this respect. They don’t like to promote themselves, and once they find a job area that interests them they will show a depth of focus in the role.Work preferences of High Energy individuals:Having a variety of challengesBeing involved in new ventures and changesMeeting new people (both internally and externally)Work preferences of Low Energy individuals:Working in a technical speciality where they feel they are an expertRoles which can be done without having to work with othersA more sedate, quieter working environment free from distraction and noiseAffectionPeople who score strongly on Affection need to feel that their work has meaning. Though they tend to stay working in one broad area, they seek to broaden their horizons within that field, looking for interesting alternatives to what they are doing. At the other end of the scale, people with low scores put a much more PERSONAL focus on their career. They want to get out of it what they put in.Work preferences of High Affection individuals:Having a sense of companionship at workWorking for a worthwhile causeThe ability to help others and contribute to the communityWork preferences of Low Affection individuals:Being rewarded proportionately to the effort they put inThe opportunity to shine in a competitive senseHaving clear objectives that aren’t open to interpretationControlPeople with High Control tend to develop their careers in a logical and planned way. They want to know where they are going and that they are on track to reaching their goals. People with Low Control have a very different attitude. They want to work in roles that allow them to do their own thing and give autonomy and flexibility.Work preferences of High Control individuals:The ability to organiseHaving a system or schedule to work to so they know where they standWorking with adequate resources and guidelinesWork preferences of Low Control individuals:Working in a relaxed environment without too many rulesHaving the freedom to be innovativeCompanies where individuality is valuedEmotionalityFacet5 research suggests that Emotionality does have an influence on work preferences, but not in the same way as the other factors. Rather than having specific ACTIVITIES that are appealing, Emotionality seems to be more connected to the conditions of working life. For example, High Emotionality people can worry more and lack confidence in themselves, and therefore may need more support and encouragement.We aren’t all clear of exactly what we want to do with our lives. But people are typically happier and more productive when they work in roles that match their natural preferences. And understanding the natural preferences inherent in our personality can help us to identify the types of job roles and working environments that we are likely to thrive and excel in.It also helps people become aware of why they like or dislike certain elements of their role. Realising this gives people opportunities to find strategies for better managing their working life so they can be more productive and more satisfied in their role. |

Write a activity to finding the normal to a curved surface.. ( NOTICE :- please Don't write wrong or silly answers ) |
|
Answer» -Take a small piece of thin foam or rubber.-Put some pins in a straight line on the foam.-All these pins are perpendicular to the foam.-If the foam was considered as a mirror, each pin WOULD represent the normal at the point.-Any ray incident at the point where the pin makes contact with the surface will reflect at the same angle the incident ray made with the pin - normal.-Now BEND the foam piece inwards.-The pins still represent the normal at various points.-You will OBSERVE that all the pins TEND to coverage at a point.---This will be appear like a CONCAVE mirror.-Now bend the foam piece outwards.-The pins seem to move away from each other that means they diverge.-The pins still represent the normal at various points.---This will be appear like a convex mirror.I hope my efforts will not get ruin and you'll find these answer helpful:) |

What is the meaning of contrast between fringes for optics |
|
Answer» Fringe contrast is a measure of the interference quality. Good fringe contrast is NEEDED to accurately measure interference signals. When the contrast is too low, the signal-to-noise RATIO DECREASES. Fringe contrast is scaled 0 to 1, where 0 is no fringe contrast, and 1 is perfect fringe contrast.Explanation:I HOPE IT HELPS U...PLZZZ MARK IT AS BRAINLIST...PLZZZ FOLLOW ME....❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️ |

A 5000kg elevator is to be designed so that the maximum acceleration is 10% og gravitational acceleration. What are the maximum and minimum forces the motor should exert on the supporting cable? |
|
Answer» imum FORCE is 55000 N,The minimum force is 50000 N EXPLANATION:Given as :The MASS of the elevator = m = 5000 kgThe gravitational acceleration = = 10 m/s²The maximum acceleration = = 10% of Let The maximum force of motor = NLet The minimum force of motor = NACCORDING to question∵ Force = Mass × accelerationFor maximum force∵ = 10% of i.e = 10% × 10 m/s²So, = 1 m/s² Now, Maximum force = mass × maximum acceleration So, = 5000 KG × ( + 10)Or, = 5000 kg × 11 m/s² ∴ = 55000 NAgainMinimum force = mass × minimum acceleration So, = 5000 kg × Or, = 5000 kg × 10 m/s² ∴ = 50000 NHence, The maximum force is 55000 N,And The minimum force is 50000 N Answer |

Car moving with a velocity of 10 metre per second can be stopped by the application of a constant force f in a distance of 20 m if the velocity of the car is 30 metre per second it can be stopped by this force in |
| Answer» 180 metersExplaination:We'll use the EQUATION of motion:v^2 - u^2 = 2×a×sHere, v = 0 m/s as the car stops in the end.Also, since a deceleration is happening, we'll WRITE 'a' as '-a'So, the equation modifies to become as follows:- u^2 = 2×(-a)×su^2 = 2×a×ss = (u^2)/(2×a)20 = 10^2/(2×a) => 2×a = 5s = 30^2/(2×a) => s = 900/5 => [s = 180 meters] | |
