Speed Acceleration And Velocity

Speed Acceleration And Velocity In this chapter we will look at the concepts of speed, acceleration, and velocity. As we all know gravity is a large factor in the acceleration of an object. For the purposes of this chapter we will differentiate between linear and vertical acceleration as being objects that move linearly or horizontally i.e. linear acceleration, versus objects that fall, fly, or are thrown etc. i.e. vertical acceleration. Vertical acceleration is much more governed by the force of gravity and is covered in greater detail in chapter 12 Newtons Laws. A short section at the end of the chapter addressing vertical acceleration is however included to put the area into context. You may have heard the old adage Speed kills. And you know whether you are driving your car or playing sport its a dangerous variable. Fast athletes are very difficult to handle, as are fast cars. However, having speed is of vital importance in sports. In this chapter well look at speed, velocity and acceleration and the factors that influence them. Speed, acceleration and velocity are all different. If you have ever watched a 100 meter race, you will notice that some athletes start faster than others, so their acceleration is different. Athletes finish the race at different times so their speed is different and athletes reach top speed at different stages so their velocity is different. The key terms to be covered in this chapter are speed, acceleration, velocity, distance, displacement, vertical and horizontal acceleration and velocity. The variables of speed, acceleration, displacement, etc. are about linear kinematics. Kinematics is a general term related to describing motion. Kinematics is also a branch of mechanics (specifically dynamics) that evaluates moving objects. In order to accurately describe kinematics there are certain terms that we must fully understand. They include the terms mentioned above (speed, acceleration, and displacement) and distance, velocity and position. Accurate understanding of these terms will allow us to accurately describe the movement of any object. There is often a lot of confusion about the terms acceleration, speed, and velocity. We often use the term speed in everyday language to imply all three terms and the word fast is an even more general term. Consider the following: A person can be moving fast and not be accelerating. A person can accelerate fast and not have a high velocity or high speed. A nice sporting example was the great Boston Celtics player Larry Bird. Larry Bird was very quick to accelerate over three or four steps, was not very fast at his top speed. So while Larry was very quick and dangerous over 3-4 steps, he would not make a good sprinter because his top end speed was not high. So if an object is accelerating, it is changing its velocity. Acceleration has to do with the change in how fast an object is moving. Therefore, if an object is not changing its velocity, it is not accelerating. We know that distance and displacement have different meanings. The same is true for speed and velocity. Speed can be considered as the rate at which an object covers a certain distance. Objects that move slowly cover distances in long periods of time, i.e., low speed. An object moving quickly covers distance in shorter amounts of time, i.e., high speed. If an object is not moving at all it has zero speed, zero velocity and zero acceleration. Let us consider some of these simple terms in more detail. Position: Position is simply the location of an object in space. You could consider it using coordinates on a map for example, or on a field, or gymnasium. Displacement: Displacement is simply the straight line distance an object has travelled. Distance: Distance is how far an object has travelled in any direction. It is also viewed as the total amount of displacement (regardless of ending position). Look at this simple example. Lets say a basketball court from baseline to baseline is 25m. If a player runs baseline to baseline and back what is his displacement and distance? Distance. This is the easy one since he ran up and down the court so that is 25m + 25m = 50m. Displacement. Since the player ran down the court and back again he ended up in the same place he started. So even though he covered a distance of 50m his displacement is actually zero, since he is back where he started. Lets say the player now runs up and down the court twice. His distance covered would be 25m + 25m + 25m +25m = 100m. Since he ended up back where he started his displacement is still zero. Finally, lets say the player runs from one baseline to the other and stops. In this case both his displacement and distance are the same at 25m. For the most part we use distance rather than displacement to describe movements as it is difficult to correctly measure displacement as we make a lot of turns when we travel. You say displacement is really like the old saying as the crow flies which means straight line. For example, the distance you travel in a car from New York City to Boston might be 250 miles (but your displacement is only 175 miles). When you drive in a car you get on the highway and follow the roads around the coast, over bridges, around hills, around towns etc. However, when you fly the plane flies right over everything in a straight line and you end up only travelling 175 miles (your displacement). Speed Speed is a very general term. Speed is a scalar quantity and is described as Distance divided by time (D/T, where D=distance and T=time). Scalar implies that speed has magnitude but not necessarily any direction, for example temperature or volume. People often use speed and velocity interchangeably but they are different. Speed relates to the distance an object has traveled, while velocity refers to the displacement that has taken place. So, the speed of an object tells us how far an object has traveled in a given amount of time but doesnt tell us anything about the direction in which it traveled. It all sounds a little heavy on the definitions but these are important. Therefore: Average speed = Distance traveled (m) Time (s) Now there are also different types of speed. We refer to them as average speed versus instantaneous speed. When an object is moving it often changes its speed (or direction) during its motion. When there is a change in speed we can alter our definitions. Instantaneous speed is the speed at any given instant, while average speed is the average of all the instantaneous speeds. For example, lets say a runner runs 400m in 60 seconds and crosses the line at 18 kmh or 5 m/s. This means his average speed over the 400m was 6.66 m/s even though he crossed the line at 5 m/s which is his instantaneous speed at the finish line. In other words, he was slowing down as he was getting to the end. If you have ever ran a 400m race then you will now how tired you are at the end and are definitely slowing down. How did we do these calculations? Average speed = Distance/time 400m/60 seconds 6.66 m/s The instantaneous speed recording of 5 m/s would have been measured with a radar or timing device. You could also look at various split times for different portions of the race. Many coaches do in fact do this, so a 400m coach might look at each 100m split and look at both the acceleration and deceleration patterns and average speeds during each of the four separate 100 meters. Here is another problem for you to try. Can you calculate the average speed of a swimmer that completes the 200m butterfly in 2.15 seconds? Answer: 2.15 seconds = 135 seconds. So 200m/135 seconds = 1.48 m/s A 400m freestyler swims the race in 4.10 seconds. The 200m split was 2.02 seconds. Can you calculate the following? a. What was the swimmers average speed for the race? b. What was the difference in speed for the first 200m versus the second 200m? Answer: a. 400m/250 seconds = 1.6 m/s b. First 200m split = 1.64 m/s Second 200m split 1.56 m/s As you can see, the swimmer slowed down over the second 200m. Velocity Velocity is somewhat similar to speed but velocity involves both direction and speed. So, whereas speed is a scalar quantity, velocity is a vector quantity, that is, it has both magnitude and direction. Velocity also uses displacement as opposed to distance. Remember displacement is measured as the straight line distance an object travels from starting to ending position. Velocity is direction sensitive since it is dependent upon displacement. Therefore, when you calculate velocity, you must also keep track of direction. Therefore, if you say an airplane has a velocity of 600 kmh, you would actually be a little vague. You should really say the airplane has a velocity of 600 kmh North. So, speed doesnt worry about direction, velocity does. Velocity is a positive number as we dont have negative velocity. So to summarize, a airplane traveling at 600 kmh as a speed of 600 kmh. The same airplane has a velocity of 600 kmh, North. Finally, the same airplane probably had little acceleration in the middle of its trip as it would only need positive acceleration and negative acceleration during take off and landing. Here is an interesting and challenging little problem for you to solve. Can you fill in the following table with acceleration, speed, and velocity data? We know the following, the direction of travel is south and acceleration doubles every second. If youre feeling confident you can also try and calculate the total distance that was covered over the 6 seconds. Hint! You can use the velocity for each second to help you. Average velocity = Displacement Time Let try some additional calculation examples: For example, if an athlete runs around a 400 meter track in 50 seconds we can calculate numerous factors. What was the distance traveled? What was the displacement? What was the average speed? What was the average velocity? 1. What was the distance traveled? Answer: Easy enough = 400 meters 2. What was the displacement? Answer: Since the athlete ended up in the same place as they started, displacement is equal to zero. 3. What was the average speed? Answer: Speed = Distance/Time = 400 m/60 seconds = 6.66 m/sec 4. What was the average velocity? Answer: Velocity = Displacement/Time = 0/60 seconds. In this case we end up with a value of zero and in this scenario average speed is a better indicator of overall performance. In many situations we actually calculate average velocity as speed because we cant gather the correct information to calculate speed. For example, if a punt returner catches the ball on the 20 yard line and then avoids a few tackles to ultimately score a touchdown twelve seconds later, we assume the punt returner ran 80 yards. In fact, they may have run 100 yards with all the turning and weaving but we cant accurately calculate the true distance traveled and instead use displacement. For our purposes in sports, thats okay. You try the following problem. Review Problems Can you accurately calculate average speed, velocity, distance and displacement for each of the following situations? Hint: You may not be able to calculate them all accurately. Problem: 1. A punt returner catches the ball on his own 40 yard line and scores a touchdown nine seconds later. 2. A 100 meter sprinter runs the 100 meter in 10.0 seconds flat. Acceleration The law of acceleration is Newtons second law and basically states The change of motion of an object is proportional to the force impressed and occurs in the direction in which the force is impressed. So far we have talked about speed and velocity and performed some calculations. However, while speed and velocity are valuable components, they tend to provide us with summary information and very little about specific detail. For example, if we consider the data for a 200 meter race run in 20 seconds we know that average speed was 10 m/sec. However, we would not know any information about who accelerated the fastest or who was leading after 100 meters. This information is also important as it helps with identifying strength and weaknesses in athletes and in developing training programs for particular athletes. The measurement of acceleration is important. Acceleration is the rate of change in velocity. Therefore, when acceleration is zero, velocity is constant. So when an object changes speed either by slowing up or down, or changes direction, it is accelerating (or decelerating). We can calculate acceleration by measuring the difference in velocity over the time it took for that ch ange in velocity to occur. Consider this: If you were to watch a 100M race the person leading at the 50M mark doesnt always win the race. The reason for this is that runners have different acceleration and deceleration rates, in other words their speed changes. Athletes vary dramatically in their acceleration. Some athletes are very fast over 40M but not over 100M and vice versa. So: Acceleration (a) = Velocity2 Velocity1 Where V2 is velocity at T2 Tim Where V1 is velocity at T1 Sometimes you will see this presented as the change in velocity (Delta sign à ¢Ã‹â€ Ã¢â‚¬  ) or the change in time (à ¢Ã‹â€ Ã¢â‚¬  T) A = à ¢Ã‹â€ Ã¢â‚¬  V à ¢Ã‹â€ Ã¢â‚¬  T Look at the following acceleration example. Question: A sprinter leaves the starting block at 2.5 m/s. One second later they are traveling at 5.5 m/s. What is the acceleration rate? Answer: V2 V1 = 5.5 m/s 2.5 m/s = 3 m/s squared T 1 You will note that we end up with meters per second squared as our answer would really be presented as 3 m/s/s. Heres another problem to try. Question: A punt returner catches the ball standing still and begins to return. Two seconds later his velocity was 5 m/s. What was his average acceleration over the first two seconds? Answer: V2 V1 = 5 m/s 0 m/s = 3.5 m/s squared T 2 So far we have looked at relatively straightforward examples of speed, acceleration and velocity in that they have all been examples of horizontal movement. Now let us discuss the vertical components of projectile acceleration, speed and velocity. Factors Affecting Acceleration Linear acceleration is affected by many factors and you will recall from chapter ? that the mass of an object is a very important one. Heavier objects accelerate more slowly with a given force. This has to do with both inertia and mass. Heavier objects are harder to both accelerate and decelerate. Think about how easy it is to throw a basketball versus a medicine ball. There are some other points to consider when looking at acceleration, speed, and velocity. First, we now know the units for velocity are meters per second (m/s) and meters per second squared for acceleration (m/s/s). For speed they are also m/s. Since acceleration (like velocity) is a vector quantity, it also has direction associated with it. The direction of acceleration depends on two factors: a. Whether the object is speeding up or slowing down b. Whether the object is moving in a negative (upwards) or positive (downward) direction We can simplify this by saying that if an object is slowing down then its acceleration is in opposite direction of its motion. If it is speeding up then its acceleration is in the same direction as its motion. Therefore: Acceleration (m/s2) = mass (kg)/force (newtons) Vertical speed, acceleration and velocity If you were to throw a ball up in the air and then catch it again at the same height as you released it, how would the ending velocity be? Would it be greater, less, or the same as the release speed? If you guessed the same you would be correct. You see, all objects, whether traveling vertically or horizontally, are subjected to the constant force of gravity (9.81 m/s2). This means that as soon as the ball left your hands it started to negatively (de)accelerate at 9.81 m/s2 until it had no more velocity. Then, it started to positively re-accelerate over the same distance (and time) at a rate of 9.81 m/s2 until you caught it again. This is a very neat relationship as it allows us to make many calculations based on this constant acceleration force. Projectiles are subjected to both vertical and horizontal components in their motion. The horizontal components are affected by the mass of the object and the acceleration force as previously mentioned. The vertical components are also affected by these two factors plus gravity. Consider this statement: A ball shot horizontally (at zero degrees) has the same vertical component as a ball that is simply dropped with no horizontal velocity. What this means is that if you were to throw a pass from your chest and it hit the ground 15 meters away 1.5 seconds later, and at the same time drop a second ball straight down from the same height, they would both hit the ground at the exact same time. What this is showing us is that the force of gravity component is acting consistently regardless of whether the ball has a horizontal component or not. In other words adding a horizon tal acceleration component does not affect in any way the force of gravity. Remember also that gravitational acceleration is a vector quantity comprising both magnitude and direction and acceleration is a squared variable to the magnitude of the force of gravity. This means that for every second an object is in free fall it will accelerate by ad additional 9.81m/s2. Thus the total distance travelled is directly proportional to the square of the time. Or we could say that if an object travels twice the time it will travel four times the distance. If an object travels for three seconds it will cover nine times the distance, for four seconds it is sixteen times the distance travelled in the first second. Look at the following. A coin is dropped from a cliff. The table shows how fast it is travelling at different time points. Question: A boy drops a ball from a balcony and records a time of 3 seconds for the ball to hit the ground. At what velocity did the ball hit the ground? Answer: 29.43 m/s How do we get this answer? Well, remember that gravity acts as a constant 9.81 m/s2. What this means is that for each second the ball is in flight it accelerates an additional 9.81 m/s. So: Insert schematic to demonstrate after 1 second = 9.81 m/s after 2 seconds = 9.81 m/s + 9.81 m/s = 19.62 m/s after 3 seconds + 19.62 m/s + 9.81 m/s = 29.43 m/s This is a simple illustration of the concept. Next question, what velocity would the ball have to be released at ground height for the boy to catch it on the balcony? Answer: A minimum of 29.43 m/s. The answer is the same because gravity and acceleration (or deceleration) is working to the same effect when the ball is moving upwards. This is sometimes referred to a negative acceleration. Question. A boy is standing on a balcony and is curious about how high the balcony is from the ground. The boy drops a ball and records the time it takes to hit the ground. It took 3.2 seconds for the ball to hit the ground. The boy concludes that the balcony is 66.7m high. How did he work it out? Well at the end of the first second the ball was travelling 9.81m/s, at the end of the second the ball was travelling 19.62m/s, at the end of the third second the ball was travelling 29.43m/s. If you add these three distances together you get 58.86 meters travelled after three seconds. If the ball travelled another full second it would travel another 39.24m, but it only travelled in this zone for 0.2 sec. So, 39.24m x 0.2sec =7.84m. Now we add the 58.86m + 7.84m = 66.7m, and thats our answer. There are some other factors to consider with vertical projectiles. The pattern of change in vertical velocity is symmetrical about the apex of the trajectory. So not only does the object land at the same speed it was released, it also follows the reverse flight path on the way down. Using these constant parameters we can now extend our calculations into more complex situations. For example, lets say you are watching a volleyball game in a high school gym with a 10 meter high ceiling. An opponent spikes the ball over the net and a player digs the ball at ground level at which time the ball has a velocity of 15 m/s. The question is will the ball hit the ceiling? To solve for this we can use an equation that combines several variables we talked about already. Where: V2 = velocity at time 2 V1 = velocity at time 1 a = acceleration t = time In order to answer this question we need to look at what we know and what we want to know. Well, we want to know the distance (d) the ball travels. We already know a = 9.81 m/s2 and we know V1 = 15 m/s. We also know that at the apex the velocity is zero, so V2 can be set to zero. So now our formula looks like this: 1. 0 = V1 squared + 2ad 2. 0 = (15 m/s) squared + 2 (-9.81 m/s squared) x d Now if we rearrange to solve for d our formula looks like: = (19.62 m/s squared) x d = 225 m/s squared = d = 11.47 m The answer is yes! The ball will hit the ceiling as it will travel 11.47 m. Heres another similar problem: A ball is deflected vertically at 18 m/s and the ceiling height is 11 meters. Will the ball hit the ceiling? Factors affecting projectile motion We have discussed several factors that affect the movement (or acceleration) of an object. The factors that affect vertical acceleration are the mass of the object, the force (speed) of release and gravity. Horizontal acceleration is affected only by mass and force of release (application). Gravity is of course a factor but not in determining its horizontal component. But sometimes we want to throw objects e.g. discus, hammer, etc. and while these projectiles are influenced by force and mass, there are other factors that influence how far the projectile will travel. We generally recognize three other factors that influence how far a projectile will travel when a constant force is applied. They are: 1. Angle at which projectile is released. 2. The speed of release. 3. The height of release. The optimum angle of release to increase horizontal displacement is 45 °. Projectiles released at over or below this angle will not reach their greatest distance. Look at Table 1 to see how distance traveled varies with changing angles of release. You will see from table 1 that the optimum angle of release is 45 ° and after that the decrease in distance traveled is symmetrical as height compromises distance (I.e. follows the same pattern as increasing angle of release up to 45 °). The greater the speed of release the greater the distance a projectile will travel. This holds true simply because there is a greater acceleration force applied in the first place. Simply put, if you want to throw a ball further you need also to throw it harder. The greater the height of release the greater the distance a projectile will travel. If you consider field sports in athletics you will notice that most successful hammer, discus and javelin throwers are taller, giving the mecha nical advantage over shorter competitors in that event. If you were to throw a ball from the top of a building it would strike the ground much further away than it would if you were to throw it from standing on the ground. If you have watched a discuss competition or a hammer throw you might notice that these athletes are quite tall (often over 1.9m). The reason for this is that these athletes have an advantage over their shorter counterparts as their angle of release is already several centimeters higher. Summary This chapter has provided a basic introduction to the concepts of speed, acceleration and velocity. We have also looked at how differentiating between these variables is important and sometimes difficult. Using some known constants, such as the accelerating force of gravity (9.81 m/s2) allows us to calculate and even predict the speeds, velocities and flight paths of selected projectiles. We have also discussed other factors that affect projectile motion such as height and speed of release. While this information is very important, it is a basic introduction as there are many other more complex factors affecting speed, acceleration and velocity. We did not talk about shape or design or, indeed materials which also play a role in the way particular objects react to forces. The factors are extremely important but for now are beyond the scope of this text. Following this section are additional problems for you to solve and practice.

Empowerment of the Employees in the Hospitality Industry Essay

Introduction Human Resource Management group of any type of business group play a great role in any organization’s progressive procedures. This is especially true in terms of the organization’s joined in the hospitality industry. Most likely, it is agreeable among all business organizations that the people or the target market is the main source of the â€Å"blood line† of any business group at that. Constant referral of the people as the main source of life for the said organizations certainly leads to the idea that most of their activities and business operations are aimed to please the clients that they ought to serve basing on the products and the services that they offer for public consumption. This is the reason why understanding the primary role of HRM in the progressive procedures of the said hospitality industry organizations is an important factor that must be dealt with in examining the progressive factors that contribute to the advancement of the hospitality industry within the American society as well as around the world. The fact that the key role of the employees within an organization is to keep its reputation up with regards the service that the company gives to its clients, there should be a certain span of attention given to their motivated progress as part of a progressing company as well. However, to know the most important factor contributing to the progression of this discussion, it is important to examine what really is the hospitality industry pertaining to? Background of the Study The business organizations making up the hospitality industry are mainly those that are serving the social market with the best service that they are able to offer to the human community. Overall, the organizations that are concerned with servicing the human society at the best possible process that they could are considered a member of the hospitality industry. The organization’s constant aim of giving state of the art service to the people makes them survive in the industry that they are involved with. To give at least a much vivid picture of the industry, the discussion of its four major branches shall help in the process of comprehension of the issue being talked about. The said four branches of the hospitality industry include (a) Accommodation Service Providers, which includes hotels, public houses for rent, motels, resorts and sanatoriums; (b) Travel and Tourism, which includes travel agents, airline cabin staff and travel technology; (c)Bars and Clubs which includes nightclubs and public houses; (d) Service and Support such as accountancy as well as occupational health and spa. The branches mentioned herein show the obvious fact that the organizations that are involved within the said industry tries to pioneer in the market of entertainment and servicing activities that actually ease the responsibilities of the human society. Since this is a fact that makes up the entire hospitality industry, it should be considered that human effort is a very important factor in the progress of the said industry. Hence, empowering them and giving them the attention that they need for them to be motivated enough to perform the best possible service that they could offer both the company and their clients as well. This particular procedure of taking care of the inner force of certain servicing organizations indeed affects the overall reputation of the entire business that also affects its performance in the world trade market. This is the main reason why it is very important for the administrations of several servicing organizations to understand the impact that motivational procedures have on the status of the progressive steps that the business groups are trying to aim for and complete within their operational engagements. This is where the involvement of the Human resources Management enters the situation. The motivational procedures that they are taking into consideration actually affects the performance of the entire business organization in the industry. Human Resources Management: The Challenges and Changes The need for having strong health assistance systems in large urban cities in the United States as well as other highly industrialized countries around the world is a challenge to many medical institutions that provide the needed services for such concerns. This is where the role of the Human Resources Management comes in. As known to many, this kind of issue demands a high shift on the human resource systems that a certain company uses. As for medical institutions such as Mt. Carmel and Tucson Medical Center, hiring and retaining employees within the work loading systems of the medical institution was much of a hard challenge for them. In the paragraphs to follow, the issues along with the responsibility of the Human Resource Management team of both medical institutions shall be discussed. The resolutions made for the said issues would also be tackled afterwards. The HRM Responsibilities The Human Resource Management Department or team is a common section that every profit or at times even non-profit organizations have. The reason behind the constant existence of this bisection in every organization is the fact that it has so much control over the staffing systems as well as providing the people within the organization with what they are due as well as with what they need (Clarke, 1998). In this regard, the importance of the presence of this organizational sector is then essential for keeping and motivating employees do their best in their assigned duties. As mentioned earlier, the challenge that has mainly directed HRM teams of both Mount Carmel Medical Institution and Tucson Medical Center to resorting to some revolutionary solutions to be able to meet the said challenges. Indeed, the responsibility that they have towards the employees that include providing them with what they need while still upholding the objectives of the institution to gain the best possible profit solution for the organization. The balanced view towards these needs have to be addressed thoroughly by the HRM team. By doing so, they are expected to provide the stakeholders of the organization with what they needed at a best possible solution (Keener, 1999). Before, the solution that both company’s HRM team was hiring temporary nurses to fill in the need. However, in due time, temporary nurses were not able to fill much of the needs of the said medical institutions. The Best Solution With the introduction of new technology and information processing systems through the internet, the revolution of network based staffing remedies hosted by some information programming companies has been the best possible solution for many people support techniques that different organizations in the business industry use today. This fact has also been proven true by the way Mount Carmel and Tucson Medical Center have faced the challenge of effectively using the human resources that they already have and doing away with hiring temporary nurses to fill in the void positions in the hospitals. At first, the HRM team of both medical institutions has had doubts on how effective the online processes could be for their employees. However, when they saw that the said program would be much beneficial both for the hospital’s objectives as well as with the employees, they took the chance of implementing the said resolution. As a result, this system has provided both institutions with so much ease and best results for the services that they offer to their clients who are hoping for excellent healthcare provisions. Implementing such programs have fully equipped the Human Resource Management teams to rearrange the staffing system in the institutions they work for while also being able to provide the organization with what they expect from their service operations. However, the said implementation also has its own disadvantages as further enlisted by Maureen Minehan in the article â€Å"Technology’s increasing impact on the workplace†. The said advantages are as follows: †¢ Portability †¢ Discrimination †¢ Legal issues †¢ Worker’s compensation and liability scheduling (1997) The said issues are considered to be among the least yet most important details that must be considered in the implementation of online programs for staffing employees. Minehan further adds that it would not be so much a surprise that because of the implementation f such technological systems, the said techniques that are governed by technological advancement â€Å"would eventually change, thus also affecting the activities of the HRM teams of the organizations† (1997). The existence of the new technological innovations on information sharing is indeed a gift to the social systems, especially organizational systems that exists today. However, like other remedies, the said innovations have their own advantages and disadvantages once they are implied. Hence, this is the main reason why the Human Resources Management teams are further faced with the challenge of whether to apply the said technological innovations in their company’s system or not. The important thing though is the idea that whether they would implement it or not, the main focus of their job is to provide the company and its employees with the best benefit that could get from the service that they render the clients of the organization. By being focused in the said responsibility, it would be easier to choose on whether to implement the technological programs or not. Management and the Hospitality Industry T, take for example the Australian economy. The Australian community is made up of a large number of minorities or immigrants who have been entering the boundaries of the country searching for employment. Hence, through this particular truth, it could be observed that the management teams of the business organizations in Australia faces the challenge of dealing with the differences of the people who are employed in the country especially in the hospitalityindustry (Leat, 2001, 14). This is particularly the one of the reasons why management and its procedural applications could not simply be passive agent in the foundation of a fine employee relations structure.(Greenwood, 2005, 19) The fact that the internal effects of globalization is focused upon the idea of employing people more than ever, the Australian retailing industry primarily aims to commit its services to the people as much as it could. Along with this, the business organizations are given the high privilege of making a difference in the society, aiming to continuously allowing people see the fact that through employment, they could be able to satisfy their needs and their demands with regards an aimed lifestyle that they have always dreamed of for them and their families as well (Kaufman, 2003, 25). This particular truth on employment satisfaction is the primary reason why the management teams are established. TO be able to motivate the employed personnels for them to work with the goals of the organization along with their personal aims as well, It is necessary to develop the ways by which the management is able to provide them with the satisfaction that they need (Kaufman, 2003, 19). This is the way by which an employee relations procedure is established for the betterment of the entire workforce of business organizations. Hospitality Organizations are expected to control a large number of employees as they are mainly empowered by the selling abilities of salesclerks and cashiers and other rank and file positions within the organization. Creating a fine working environment for the employees would certainly help in the establishment of a strong business organization. Through policing and employee relations establishment the said motivational factor that would assist the employees in working their efforts towards the right path of success is indeed needed.(Greenwood, 2005, 56) This is where the management procedures practiced by the management teams of different organizations enters the scene. Several hospitality companies in Australia are paying much to be able to help their workforce have a clear motivation towards their goals as well as with the company’s goals (Bruce, 2004, 21). Conclusion Continuously sticking to the example carried herein with regards the Australian economy, it could be noted that there are those that preempt the industries in Australia as neither as strong or even a weak status in the world economy. At some point, the said reactions are derived form the fact that the hospitality industries are at some point lacking the capability to assist their employees in reaching their goals making it harder for the workforce to perform well, which might result to lesser successful accounts of profitable outcome for the Australian economy. This is where the importance of human resource management should be strongly applied among hospitality organizations. From this perspective, it could be observed and thus proven that the management sector of any organization is definitely not a passive agent when it comes to empowering the human relations of certain business companies especially in the Australian Hospitality Industry (George, 2005, 65). Most often than not, it could be noted that the Management team even has the largest responsibility in creating the possibilities for a larger, more successful employee relations within the hospitality industry systems. Especially taking into consideration the major role of the human resource management in empowering the people of those who are working within the hospitality industries, it could be observed that people are supposed to be served and be serviced at the same time. The ability of the human resource management to create possibilities by which the stakeholders of the organization would actually benefit from could actually help the said industry grow towards its peak servicing operations within the human society. From the study presented herein, it could be noted that there are several responsibilities that the HRM need to attend to. However, because of the focus that they have to put on empowering their own people, they need to balance the aspects that they ought to take into consideration in actually completing their responsibilities.

How Hair Detangler Works and Recipes to Make It

If you have long hair, chances are youve experienced the pain and frustration of trying to comb out snarls. Hair detangler is like a magical elixir, able to smooth away your cares with the spritz of a pump or wave of your hand. How does it work? Its an example of chemistry in action. Hair Detangler Basics Although there are many possible ingredients in hair detangler, they all work by altering the surface of your hair. Hair detangler is a type of hair conditioner that smooths your hair by coating it with an oil or polymer and/or by acidifying it so that the hairs surface tightens up, smoothing the scales on the hairs outer surface or cuticle and imparting a positive electrical charge to prevent the static that can worsen tangles. Common Chemicals in Hair Detanglers If you check the ingredients list of a hair detangler, youll likely see one or more of these ingredients: Silicone (e.g., dimethicone or Cyclomethicone), a polymer that adds gloss to hair by binding to its surface.Acidifier, a ​chemical that lowers the pH of the detangler, strengthening the hydrogen bonds between keratin molecules in hair, smoothing and tightening each strand.Hydrolyzed Protein helps to repair damaged keratin, smoothing the broken edges so strands of hair dont catch on each other as much.Cationic Surfactants binds to the negatively charged keratin, becoming the new smoother surface of the hair.Oils fill in the pores of dry or damaged hair, making it softer, more pliable, and less likely to tangle. Homemade Hair Detangler If you dont have detangler on hand, you can mix up some yourself. There are several options: Dilute regular hair conditioner. Spritz a mixture of 2 tablespoons conditioner in 16 ounces of water onto damp hair.Fill a spray bottle with the following herbal hair detangler mixture: 8 ounces distilled water1 teaspoon aloe vera gel10-15 drops grapefruit seed extract1-2 drops glycerin1-2 drops essential oil (e.g., lavender, jojoba, chamomile) Rinse hair with rainwater (usually acidic) or make your own acidifying rinse by adding 2 tablespoons apple cider vinegar to an empty 20-ounce water bottle. Fill the remainder of the bottle with water and use the mixture to rinse clean hair.Rub tangled dry hair with a dryer sheet prior to combing it out.
