Humans Senses and Perceptions Essay examples - 1418 Words

Humanity is blessed with at least five senses with which we observe and perceive our surroundings. Although our senses, and sense perceptions indeed are amazing, the knowledge gained by these faculties is sometimes misleading. The reason why our senses, at times, err is twofold, first the sensory organs we are endowed with are not entirely accurate, and are not equipped to perceive and measure all information. The second reason for errors in perception is that we all interpret the data we revived via there organs differently. As Penelope Fitzgerald puts it, â€Å"No two people see the external world in exactly the same way. To every separate person a thing is what he thinks it is -- in other words, not a thing, but a think.† The combination of†¦show more content†¦We err in this case because other people want us to, and they have easy access to our perception and opinion through our fallible senses. It is because our senses are fallible that scientists try to create i nstruments that will allow us to hear and see better: such as telescopes, microscopes and microphones. Also ultrasound and x-ray refraction can be used to â€Å"see† things like atoms, which would otherwise be impossible with our eyes alone. Although, if the only reason we err came from flaws in sensory organs technology should be able to give us completely accurate perception...right? However while light and sound may enter the ears and eyes it is not perceived until it reaches the brain. Therefore the acquisition of knowledge, or sensory deception relies on the mind , making it nearly impossible to attain perfect perception. So, we will always err because of our mind, and its limitations. Although we do have eyes to see with and ears to hear with, there sensory organs are imperfect, and only perceive a fraction of what is really going on around us. In order to prevent our brain from overloading with the massive amounts of sense data it receives, our brain tends to filter wh at is going on around us. For example, in a classroom there is an instructor, other students, and various other distractions. A student cannot possibly focus on all of these and oftentimes chooses to focus only on the other students and various distractions.

Case Study Autism 7th Grade - 1066 Words

Task 2 Case Study The first day of student teaching in the first period I observed a child named ‘Kyle.’ Kyle seemed to get out of his seat even after my mentor teacher asked him to sit in his seat. He was at the front of the class very close to where the teacher taught. After a few times of this he growled at the teacher. I could tell that he was different than the typical student because of his constant interruptions. I found out after the class Kyle was autistic and had behavior problems. I also found out he was operating at an age level of 6 to 7 years old. This behavior happened often so all the 7th grade teachers composed a chart for Kyle to reward him for staying on task but didn’t seem to work. Kyle is interested in science,†¦show more content†¦Once I graded Kyle’s note-taking sheet with map, he had all labels on his map. This also made me believe he liked the visual map and being able to see countries, bodies of water, and cities. I will use a map in the n ext unit as well. Besides his assignments I had a few objectives I wanted Kyle to accomplish but with no punishment if they were not met. After a gladiator video we watched together, Kyle’s objective was to state the main idea of the video with 80% accuracy, and since it was verbal he was able to correctly state the main idea. Another objective he was able to reach was to transition appropriately from tasks and activities and school environments 80% of the time given visual and verbal prompts. This objective was met 6 out of 8 times throughout the unit. Overall, a big objective for Kyle was to follow classroom rules and directives given visual and verbal prompts 90% of the time. He was able to reach slightly under 90% of the time in the class I taught but this was a yearlong objective that all his teachers participated in. Finally, it is so important that Autistic children have structure, routine, and praise. In Kyle’s case he did not like writing which is an important part in history. By reducing his assignments, asking for verbal answers instead of written answers, verbally reminding everyone to stay on task, and providing written and verbal instructions, I was able to meet my objectives through the assessments.

The Collaborative Economy Business Model †MyAssignmenthelp.com

Question: Discuss about the Collaborative Economy Business Model. Answer: Introduction The collaborative economy business model is now considered being a known occurrence in respect of customers as well as businesses throughout the globe due to the technological development. The strength of individuals participating in the collaborative economy has increased immensely and businesses like Airbnb as well as Zipcar functioning amid its impact are in equal competition with large chain of hotels as well as car rental services. There will occur the existence of the collaborative economy only when individuals will be having the willingness for sharing. However, in respect of sharing there is the need for both the parties in being reliable. Therefore, it is necessary that the users as well as the owners of the business do the leveraging of reviews for providing assistance in building reliance all through the process. Also, due to the development in the technological aspect, there is occurring a bright future in respect of the collaborative economy. For getting success in the c ollaborative economy, the companies are required building the trust among the users and do the conveying of authenticity as well as transparency. In this respect, there is the requirement for having awareness regarding the four significant values that are associated with the social aspects, economic aspects, practical aspects as well as sustainable aspects, and integrating them as a significant part of the collaborative economy experience. In respect of Airbnb, it can be stated that the company does the selling of products that are considered being uncommoditized. Individuals are caring a lot on respect of where they would stay and therefore, variety is considered being significant. The key is the process of listing. Airbnb is having at present, more than a million listings. In addition with the economic advantages, collaborative economy will be contributing as well to new experiences, new associations and, most importantly, the capability of getting the service or product at a convenient time as well as location. Advantages and disadvantages of the collaborative economy Collaborative economy is also considered as the sharing economy that will be allowing individuals in sharing assets, services as well as time with other individuals and getting incentives, in monetary or in kind. Nevertheless, collaborative economy is having its own advantages as well as disadvantages. Collaborative economy has brought with itself various opportunities related to outsourcing. There occurred benefit for businesses through the supply of part-time workers that are having the availability at reduced expenses. They will be hiring freelance workers and will be continuing to do their employment when they prefer. Uber as well as Task Rabbit are considered being the examples of such organizations (Lu 2016). This aspect states that the collaborative economy is considered being effective in respect of businesses and professionals. Amongst the other advantages of the collaborative economy, lower cost is considered being an advantage along with affordable price and regarded as one of the major criteria associated with the selection of collaborative economy. For instance, to rent a luxury apartment on Airbnb can be compared to the price regarding a hostel and a ride utilizing BlaBlaCar will not be costing more than a train ride. Along with the economic advantages, collaborative economy will be contributing as well to new experiences, new associations and, most significantly, the capability of getting the service or product at a convenient time as well as location (Zhou 2015). For instance, there occurred the launching of the Airbnb service naturally when decision was made by the homeowners for renting it out to the conference visitors when there wasnt the availability of any hotel rooms. Irrespective of the various advantages, collaborative economy is also having certain disadvantages as well. One of the major concerns is associated with the aspect of lacking adequate attention relating to security concerns. For instance, Airbnb can also do the raising of issues relating to customer safety as well as annoyance in respect of the hosts neighbours. Hotels are having regular inspection for ensuring that they there are no fire traps and they are not posing any threat respect of the visitors. But, the hosts of Airbnb are not facing any such scrutiny. Also, in respect of Uber it can be stated that the company is presently having disagreements with the regulators over whether its cars are meeting the safety as well as insurance needs imposed on normal taxis (Norman 2017). One more disadvantage of the collaborative economy is that it will be leading towards the degradation of wages. Description of an industry being challenged by a collaborative economy model The hospitality industry is being challenged by the collaborative economy model. With the coordination of transactions through the internet and taking place amongst private individuals, key brands within the hospitality industry is facing the economic influence of the online resource sharing platforms. It has been estimated that the hotels are losing approximately $450 million in direct revenues every year to Airbnb. According to a report, between September 2014 and August 2015, there occurred the reservation of 480,000 hotel room nights while there occurred the booking of more than 2.8 million room nights on Airbnb. By 2018, it is being estimated that Airbnb room nights will be reaching 5 million every year (Kitchin 2016). Therefore, it is clear that Airbnb (vacation rental site) has reduced the demand in respect of traditional hotel rooms (Dino 2015). In addition, many hotel staffs are facing job losses due to these plummeting demands. Also, the vacation rental site is less labour intensive in comparison to hotels since they are not requiring similar level of service. There have occurred almost 2,800 direct job losses to Airbnb and a loss of around $200 million in income in respect of the staffs of hotels. Because of the reduced demand of the hotel rooms will be occurring an additional adverse impact in respect of the hotels as well as their staffs. When guests will be selecting not to stay in a hotel then the money that would have been spent on foods and beverages at the bars and restaurant of the hotel will be spent somewhere else (Gundry 2014). As a result, the hotels are losing out on the profit they would have otherwise received from the visitors and to be precise, around $108 million of food and beverage revenue is getting lost since travellers are making the choice of booking with Airbnb. The incumbent business model in the hospitality industry has started evolving in due course of time, because of the impact of the technological, social as well as economic factors. The social factor, the changing aspect regarding the customer behaviour was having the highest influence in relation to evolution of the business models towards the innovative model of business. The new technological developments has turned out to be a way to ensure success as it is offering the scope to expand the channels of distribution, reducing the reservation processing time as well as creating the organizational network that is having the involvement towards the maintenance of the value chain (Ahlin 2014). For meeting the higher power of negotiation regarding the buyers as well as competition, hospitality companies are required making continuous innovation for maintaining their market position. Moreover, there is occurring continuous change relating to the needs of the customers, and there occurs th e triggering of this change through new technological aspects. Porters Framework of Competitive Advantage The framework of Porter will also be referring to the power of suppliers as well as buyers. The suppliers of Airbnb will be having limited power, or else their rooms will be remaining vacant. The buyers of Airbnb are similarly having limitation due to the dearth of competition in the space. They could possibly do the identification of the space they would like renting on the website of Airbnb and then contacting the seller in a direct way, evading the Airbnb premium, but to do the seller will be bypassing the insurance clause of Airbnb as well as the payment collection process. The last part of the Porters framework is concerned with the threat that the substitutes are posing. There is another service similar to Airbnb that did the actualization of remarkable opportunity but has not been able to achieve Airbnb-type profits. Couchsurfing.org will be facilitating free stays on couches in respect of members regarding their network, but the business model and experience is very much diff erent from Airbnb (Dawson 2014). Selection of an existing collaborative economy firm within the hospitality industry An existing collaborative economy firm within the hospitality industry is Airbnb. Within a span of only seven years, Airbnb did the disruption of the 1300-year-old hotel industry through the creation of a collaborative travel revolution where everyone will be capturing superior value. Airbnb started its operation in 2008 and did the creation of an online marketplace that connects travellers to the potential hosts. At present, Airbnb is having more than 1,50,000 host listings offered in more than 30,000 cities and more than 190 countries. It all begins with the basic supposition that home owners are having vacant rooms that might not be getting used. Airbnb is allowing these home owners in making some additional cash by posting these rooms on listings, together with photographs as well as details, making connection with potential guests and renting them out (Florida 2014). Airbnb is considered being a marketplace that is facilitating the exchange between the home owners as well as tra vellers and providing an online method of reservation that is facilitating transactions in an honest as well as dependable way. Having a flexible platform, transparency, trust as well as dependability, Airbnb did the management of relying upon listings as well as contents that are generated by the users. Its function is facilitating as well as assisting the value creation of other individuals and through that the value is getting multiplied in an exponential manner. In respect of that, Airbnb is charging a 3% host service fee in respect of every booking as well as 6 to 12% of the cost of reservation in respect of the guest. Unlike linear businesses within the hotel industry, Airbnb will be scaling at an incredibly fast rate at little to no marginal expense. By making their customers partners, Airbnb did the creation of a platform for the creation of value for every individual as well as sharing that value through the orchestration of the network as well as facilitation of the connections. With a solid platform, a better reputation as well as a developing community, Airbnb will be finding itself to be in a strong position for the sustenance of its competitive advantage. Through innovation as well as proven consistency, Airbnb will be continuing with the creation of value. The ways by which the collaborative business model in respect of Airbnb will be maintaining a competitive advantage is mentioned as under, One of the competitive advantages of Airbnb is that unlike hotels, it is not controlled by the growing variable costs. As an alternative, Airbnb will be offering an incredibly generous list of rooms, in countries throughout the globe. The company website is having listings in 192 different countries as well as 34,000 varied cities. Airbnb will be allowing the users in navigating these listings in an intuitive manner because of the various characteristics on its website. The Airbnb model is therefore, an example of ICT that might be lowering the costs of searching by offering a plethora of information as well as the methods for managing, processing as well as evaluating it easily (Carland 2015). Another competitive advantage of the expansiveness regarding the listing of Airbnb is the manner in which the organization will be tracking the users preferences. Along with the collection of data through the tracking of the browsing behaviour, Airbnb will be having the ability for gaining a better portrayal of its users when they sign-up for the service via the websites Facebook Application Programming Interface (API). Another competitive advantage of the company is also associated with its major investment regarding big data information technology. The major objective of such an investment is mainly learning more about the users habits as well as preferences (Anderson 2014). Identifying certain unintended outcomes of the collaborative economy model The collaborative economy is having a steadfast growth. Websites such as EBay, TripAdvisor that are relying on peer to peer communications are established, everyday services. An increasing number of sectors are having a peer to peer component, from accommodation and travel to lending as well as retail. In general, this has been a positive growth. There is occurring the circumvention of the old structures of power as individuals are providing things in respect of one another. Increasing number of individuals is having the ability of making an income from their interests, their vacant rooms as well as with the spare time they have. But from a different perspective, it can be stated that the broad shift in the cultural aspect is creating winners as well as losers (Ludvig 2016). At times, mistakes are taking place. In certain places, the authorities are acting fast for getting acquainted with the business models that are blurring the boundaries amongst the individual as well as commercia l interests in certain new as well as confusing manners (Dentchev 2016). For instance, when a website such as Zopa will be set up and peer-to-peer lending becomes a possibility, it will be undermining the voracious banking industry and will be feeling like financial power getting redistributed. When collaborative economy substitutes will be undermining the traditional small businesses, it must be dealt with utmost concern. For instance, let us consider the situation of a family-run bed breakfast that will be seeing its number of visitors getting reduced due to the coming up of new Airbnb rooms in close proximity. In another scenario, it might occur that all of a sudden, individuals start facing eviction from their rented apartments due to the fact that owner had felt he could be making more money doing temporary lets (Pacione 2014). In another scenario, taxis in San Francisco might be taken into consideration. In 2012, there was the launching of the ride-sharing app Uber and in the next two years there has been the dropping of the number of cab journeys by 65%. This might be regarded as a matter of ease in respect of the users but on the other hand, this has been proved to be a overwhelming income loss in respect of taxi-drivers (Dawson 2014). This challenging situation is occurring in Britain in recent times in respect of courier services. Certain courier services that are considered being the cheapest are keeping their costs low through the hiring of freelance drivers or lifestyle couriers. These drivers are being paid as less as 35p per delivery in certain cases, making it a very underpaid work in respect of those that are depending upon the income (Pillay 2014). There also occur concerns relating to taxation as individuals who are running little businesses on the side are not making declaration about it. There is also occurring the aspect of overlooking the rules regarding health and safety that will be getting applied to traditional businesses. Finally, it needs to be understood that there is nothing completely positive regarding peer-to-peer models of business (Cropley 2014). It cannot be assumed that these business models are always better, that there always occurs sustainability of the eco-products, or that the digital products are having a reduced carbon footprint in comparison to the physical ones. Conclusion To conclude the assignment it can be stated that the advantages as well as disadvantages regarding the collaborative economy have been explained briefly. Then, there has been the selection of the hotel industry that is being challenged by a collaborative economy model. An explanation has been provided regarding the hotel industrys incumbent model and ways to create as well as capture value. A selection has been made in respect of one existing collaborative economy firm such as Airbnb within the hotel industry. There has also been the requirement for analysing in what ways the collaborative economic business model will be able to do the creation as well as capturing of superior value. Moreover, the competitive advantage regarding the collaborative economic business model has been discussed as well. Also, there has been the identification of certain unintended outcomes of the success regarding the collaborative economy model. References Ahlin, B., Drnovek, M. and Hisrich, R.D., 2014.

Quartz has been found in meteorites and in some rocks collected on the moon. Quartz has the chemical formula SiO2. There are many varieties of quartz, which occurs in nearly all types of igneous, metamorphic and sedimentary rocks. It is an essential mineral in granites, granodiorites and rhyolites. Metamorphism of quartz-bearing igneous and sedimentary rocks typically increases the amount of quartz and its grain size. Quartz is very resistant to weathering and, therefore, concentrates as sandstones and other detrital rocks. Most sands are weathered fragments of quartz. Sandstone and quartzite are the same materials that are re-lithified (compressed into rock). Quartz has many commercial applications. In science and industry, quartz sand is used for manufacturing sandpaper and other abrasives, polishing powders and soaps. It is used to make building materials, heat-resistant materials known as refractories and for the bearings of precision instruments. Quartz sand is also used in the manufacture of porcelain, glass and metal casting molds. Precision-cut plates of quartz are used for frequency control in radios, TVs, clocks and watches. Compositionally, quartz is usually quite pure, with only traces of other elements like aluminum, sodium, potassium and lithium. Quartz is found as large crystals that are often beautifully colored by impurities. The many varieties of quartz are due to formation of different geometric arrangements of its tetrahedral crystals. This accounts for different crystal structures, and, therefore, different physical properties. To form Quartz sandstone, rock particles & remains of living things are deposited in the sea by rivers and waves. These sediments accumulate layer by layer, over thousands or millions of years, forming thick deposits on land or on the sea floor. The weight of the overlying sediments compact those below. Over time, they form sedimentary rocks. Sedimentary rocks usually occur in shallow parts of the sea or in lakes in desert areas where evaporation is higher than precipitation. As evaporation takes place, water is lost and the dissolved minerals form crystals. As evaporation continues, more crystals form and accumulate on the sea or lake floor, becoming sedimentary rocks, i.e. coal. They have a layered appearance because the materials that form them are deposited in layers. Plant and animal fossils can be found in many sedimentary rocks. Color: Very variable; frequently red, brown, greenish, yellow, gray, white. Texture: Medium-grained. Usually well sorted, that is grains all about the same size; grains sub angular to rounded (sandstone). Structure: Bedding usually apparent; current bedding and ripple marks common; graded bedding may occur. Concretions and fossils may be found. Mineralogy: Quartz is the main component but is often accompanied by feldspar, mica or other minerals. The grains may be cemented by silica, calcite or iron oxides. Field relations: Sandstones are associated with most other sedimentary rocks. Most sands accumulated either in water, usually the sea, or as wind-blown deposits in arid continental areas. Desert sandstones tend to be red, and the individual sand grains are often almost spherical and polished."
