Complete Guide to Fractions and Ratios in ACT Math

Complete Guide to Fractions and Ratios in ACT Math SAT/ACT Prep Online Guides and Tips Parts and proportions (and by expansion objective numbers) are surrounding us and, purposely or not, we use them consistently. On the off chance that you needed to gloat over the way that you ate a large portion of a pizza without anyone else (and why not?) or you had to realize what number of parts water to rice you need when making rice on the oven (two sections water to one section rice), at that point you have to impart this utilizing divisions and proportions. Basically, divisions and proportions speak to bits of an entire by contrasting those pieces either with one another or to the entire itself. Don’t stress if that sentence has neither rhyme nor reason at this moment. We’ll disrupt down all the norms and functions of these ideas all through this guideboth how these numerical ideas work when all is said in done and how they will be introduced to you on the ACT. Regardless of whether you are a predictable at managing portions, proportions, and rationals, or a fledgling, this guide is for you. This guide will separate what these terms mean, how to control these sorts of issues, and how to answer the most troublesome division, proportion, and objective number inquiries on the ACT. What are Fractions? $${apiece}/{ hewhole}$$ Divisions are bits of an entirety. They are communicated as the sum you have (the numerator) over the entire (the denominator). Amy’s feline brought forth 8 cats. 5 of the little cats had stripes and 3 had spots. What part of the litter had stripes? $5/8$ of the litter had stripes. 5 is the numerator (top number) since that was the measure of striped little cats, and 8 is the denominator (base number) in light of the fact that there are 8 cats aggregate in the litter (the entirety). Little cat math is the best sort of math. Extraordinary Fractions There are a few various types of extraordinary divisions that you should know so as to take care of the more mind boggling part issues. Release us through each of these: A number over itself rises to 1 $6/6 = 1$ $47/47 = 1$ ${xy}/{xy} = 1$ An entire number can be communicated as itself more than 1 $17 = 17/1$ $108 = 108/1$ $xy = {xy}/1$ 0 partitioned by any number is 0 $0/0 = 0$ $0/5 = 0$ $0/{xy} = 0$ Any number separated by 0 is unclear Zero can't go about as a denominator. For more data on this look at our manual for cutting edge numbers. However, until further notice, the only thing that is in any way important is that you realize that 0 can't go about as a denominator. Presently we should discover how to control divisions until we open the appropriate responses we need. Lessening Fractions On the off chance that you have a division wherein both the numerator and the denominator can be partitioned by a similar number (called a â€Å"common factor†), at that point the portion can be decreased. More often than not, your last answer will be introduced in its most decreased structure. So as to diminish a division, you should locate the normal factor between each bit of the part and gap both the numerator and the denominator by that equivalent sum. By isolating both the numerator and the denominator by a similar number, you can keep up the best possible connection between each bit of your portion. So on the off chance that your portion is $5/25$, at that point it tends to be composed as $1/5$. Why? Since both 5 and 25 are detachable by 5. $5/5 = 1$ Also, $25/5 = 5$. So your last portion is $1/5$. Including or Subtracting Fractions You can include or take away divisions as long as their denominators are the equivalent. To do as such, you keep the denominator reliable and essentially include the numerators. $2/+ 6/= 8/$ Be that as it may, you CANNOT include or deduct divisions if your denominators are inconsistent. $2/+ 4/5 = ?$ So what would you be able to do when your denominators are inconsistent? You should make them equivalent by finding a typical different (number the two of them can duplicate equitably into) of their denominators. $2/+ 4/5$ Here, a typical numerous (a number the two of them can be increased uniformly into) of the two denominators 5 is 55. To change over the part, you should increase both the numerator and the denominator by the sum the denominator took to accomplish the new denominator (the regular various). Why increase both? Much the same as when we decreased portions and needed to separate the numerator and denominator by a similar sum, presently we should duplicate the numerator and denominator by a similar sum. This procedure keeps the portion (the connection among numerator and denominator) predictable. To get to the shared factor of 55, $2/$ must be duplicated by $5/5$. Why? Since $ * 5 = 55$. $(2/)(5/5) = 10/55$. To get to the shared factor of 55, $4/5$ must be increased by $/$. Why? Since $5 * = 55$. $(4/5)(/) = 44/55$. Presently we can include them, as they have a similar denominator. $10/55 + 44/55 = 54/55$ We can't lessen $54/55$ any further as the two numbers don't share a typical factor. So our last answer is $54/55$. Here, we are not being asked to really include the divisions, just to locate the lowest shared factor with the goal that we could include the portions. Since we are being solicited to locate minimal sum from something, we should begin at the most modest number and work our way down (for additional on utilizing answer decisions to help take care of your concern in the fastest and least demanding manner, look at our article on connecting answers). Answer decision An is disposed of, as 40 isn't uniformly separable by 12. 120 is equitably distinguishable by 8, 12, and 15, so it is our lowest shared factor. So our last answer is B, 120. Duplicating Fractions Fortunately it is a lot less complex to increase portions than it is to include or separate them. There is no compelling reason to locate a shared factor when multiplyingyou can simply duplicate the divisions straight over. To increase a portion, first duplicate the numerators. This item turns into your new numerator. Next, increase your two denominators. This item turns into your new denominator. $2/3 * 3/4 = (2 * 3)/(3 * 4) = 6/12$ Also, once more, we decrease our portion. Both the numerator and the denominator are distinct by 6, so our last answer becomes: $1/2$ Unique note: you can accelerate the augmentation and decrease process by finding a typical factor of your cross products before you duplicate. $2/3 * 3/4$ = $1/1 * 1/2$ = $1/2$. Both 3’s are products of 3, so we can supplant them with 1 ($3/3 = 1$). Our different cross products are 2 and 4, which are the two products of 2, so we had the option to supplant them with 1 and 2, individually ($2/2 = 1$ and $4/2 = 2$). Since our cross products shared elements for all intents and purpose, we had the option to decrease the cross products before we even started. This spared us time in decreasing the last portion toward the end. Observe that we can possibly decrease cross products when duplicating parts, never while including or taking away them! It is additionally a totally discretionary advance, so don't feel committed to diminish your cross multiplesyou can generally basically lessen your division toward the end. Isolating Fractions So as to partition portions, we should initially take the equal (the inversion) of one of the divisions. A short time later, we just duplicate the two divisions together as should be expected. For what reason do we do this? Since division is something contrary to augmentation, so we should invert one of the portions to transform it once more into a duplication question. ${1/3} à · {3/8} = {1/3} * {8/3}$ (we took the complementary of $3/8$, which implies we turned the portion over to become $8/3$) ${1/3} * {8/3} = 8/9$ Since we've perceived how to tackle a division issue the long way, we should talk easy routes. Decimal Points Since divisions are bits of an entire, you can likewise communicate parts as either a decimal point or a rate. To change over a portion into a decimal, basically isolate the numerator by the denominator. (The $/$ image additionally goes about as a division sign) $3/10 = 3 + 10 = 0.3$ Some of the time it is simpler to change over a portion to a decimal so as to work through an issue. This can spare you time and exertion attempting to make sense of how to isolate or duplicate portions. This is an ideal case of when it may be simpler to work with decimals than with portions. We’ll experience this issue the two different ways. Quickest waywith decimals: Basically locate the decimal structure for each division and afterward think about their sizes. To discover the decimals, isolate the numerator by the denominator. $5/3 = 1.667$ $7/4 = 1.75$ $6/5 = 1.2$ $9/8 = 1.125$ We can obviously observe which divisions are littler and bigger since they are in decimal structure. In climbing request, they would be: $1.125, 1.2, 1.667, 1.75$ Which, when changed over back to their part structure, is: $9/8, 6/5, 5/3, 7/4$ So our last answer is A. More slow waywith parts: On the other hand, we could look at the portions by finding a shared factor of each division and afterward contrasting the extents of their numerators. Our denominators are: 3, 4, 5, 8. We realize that there are no products of 4 or 8 that end in an odd number (on the grounds that a much number * a considerably number = a significantly number), so a shared factor for all must end in 0. (Why? Since all products of 5 end in 0 or 5.) Products of 8 that end in 0 are additionally products of 40 (on the grounds that $8 * 5 = 40$). 40 isn't distinguishable by 3 nor is 80, however 120 is. 120 is distinguishable by each of the four digits, so it is a shared factor. Presently we should discover how often every denominator must be increased to rise to 120. That number will at that point be the sum to which we duplicate the numerator so as to keep the portion steady. $120/3 = 40$ $5/3$ = ${5(40)}/{3(40)}$ = $200/120$ $120/4 = 30$ $7/4$ = ${7(30)}/{4(30)}$= $210/120$ $120/5 = 24$ $6/5$ = ${6(24)}/{5(24)}$= $144/120$ $120/8 = 15$ $9/8$ = ${9(15)}/{8(15)}$= $135/120$ Presently that they all offer a shared factor, we can essentially look to the size of their numerators and think about the littlest and the biggest. So the request for the divisions from least to most noteworthy would be: $135/120, 144/120, 200/120, 210/120$ Which, when changed over go into their unique divisions, is: $9/8, 6/5, 5/3, 7/4$ So indeed, our last answer is A. As should be obvious, we had the option to

The qualities of compelling Groups Much can be found out about the craft of building a compelling gathering. We presently comprehend a significant number of the rules that make the best possible condition wherein gatherings can bloom and prosper. However we stay unfit to "guarantee" that any given gathering will arrive at its objectives or be anything over unassumingly effective. Notwithstanding, even a gathering made out of "the absolute best people" has some likelihood of disappointment.( ) Gatherings can take on quite a lot more hazard than people and can endeavor a degree of enormity that is past the sensible any expectation of any person.

This entry has a surprise ending

This entry has a surprise ending DID YOU KNOW? About 25% of my blog posts are partially written while doing laundry. (The “Did You Know?” opener is a throwback to the olden days of MITblogs, circa 2006. Long before my time, Sam 07 would prelude each of his blog entries with a snappy yet life-changing piece of trivia like “Paula Abdul actually isnt African American” or “McDonalds in Hawaii sell Spam.” I, however, sorely lack his flair for distinguishing useless information from interesting useless information, so I usually opt to start my entries with some useless metaphor instead.) A few weeks past, I observed that my calendar looked like it was about to suffer an aneurysm. Little denouement did I provide, so let me resolve it now: after finishing the last of four exams on Monday, I had a pleasant four-hour lapse into the depths of meditative relaxation, AKA, I ate some fruit and read Wikipedia. Later that evening, I checked my Linear Algebra grade online: Exam 1: 52.5%. I may have choked. Turn on the slow-motion cameras, and observe the brain-chilling shock in all its bizarre detail: In the beginning, there was numbness, trailed moments later by slightly grayer shades of numbness. I considered having a stroke and then decided against it, mostly because I needed to go to class the next day. Emotionally, the discovery that you have failed a test is the equivalent of eating a burrito smothered in wasabi and filled with crushed glass: confusing, painful, wildly disorienting, and refreshing in an absurd way. Now, back to normal playback: I swallowed it and moved on, eventually. I knew I understood the material, so the situation was far short of alarming. The logical conclusion was that the test somehow misrepresented my abilities in a grossly disastrous manner, by which I mean that I had probably forgotten how to add properly. Over the course of a long and ponderous night, revelations tiptoed through my streams of thought: the brutal, knife-sharp truth is that failure at MIT happens more often than some people do laundry. Best to get it over with, soak up the life lessons, and hope for a brighter future. At least I was in good company. The next morning, I felt oddly sympathetic to the enduring spirit of the Institute, as if I were suddenly engulfed in the camaraderie of endless generations of students who had been betrayed by simple arithmetic errors in their moments of greatest need. Everywhere I looked, I glimpsed the honest hallmarks of a community that was deeply, wonderfully tolerant of failure- one might even say fundamentally rooted in the acceptance of failure. There were open office hours throughout the day, tutoring sessions far into the night. Counselors. Advisors. Study breaks. Student support services. Stress-prevention pamphlets. Upperclassmen who had no doubt lived through worse. Free hand sanitizer. There it was, glaring me in the face, the luminescent fact that MIT wants you to succeed and will extend to you as many ropes as you need to pull yourself away from your mistakes and weaknesses. All you need to do is reach out. So I did. I went to extra recitation hours the next day. My back-up plan was to compose an elegant but slightly insane letter to the head of the math department demonstrating my ability to perform Gaussian Elimination on matrices. After recitation, I approached the instructor with cautious intent to eviscerate the gory inner consequences of my abysmally low test grade. I hovered. And hovered. And waited, hovering. And then, with the nonchalant grace of someone who unknowingly steps on a match and prevents a forest fire, she mentioned that the test score was out of 60. Pause. Repeat: I got a 52.5 out of 60, not 100. Which, most likely, was an A. I think this calls for additional punctuation marks!!! In retrospect, at least I built character. Now please excuse me while I check my blood pressure. Addendum: Topping my list of preferred study spots on campus is the Physics Undergraduate lounge, which, unfortunately, is accessible only to Physics undergrads and people like myself who accidentally overheard the password. Reason: Couches. I once sat down at 5:30 pm to start an 8.022 (Electricity and Magnetism) problem set and forgot to go home until 10 pm, thanks to the couches. The caffeinated murmurs of jaded upperclassmen scrambling to finish their quantum problem sets also provided for soothing waves of ambient noise during the night hours. Should anyone be interested, the textbook for 8.022 is Purcells Volume II of the Berkeley Physics Course, a borrowed copy of which I am reading right now as I type this. Be warned: its liberally salted with formulas and skimps on the meat of satisfying explanations, sort of like canned soup but easier to open. I do, however, like the spots where Purcell is like, “Oops, I forgot that Im writing an introductory-level text and now Im going to spew random theoretical physics all over the page.” Theres literally a section on Page 6 where hes like, “Charges can be positive or negative. By the way, I think quarks exist!” Also, theres a window in case the existence of outside has fled your memory. Im going to stop writing now so you guys can get back to thinking about regular action decisions. A final word: In the inexorable yet mysterious course of a human life, its not whether you get in or not that truly matters; the important thing is that you dont go to Caltech.

Variable Measurement, Sampling Selection, And Empirical...

3. Variable measurement, sample selection, and empirical design 3.1. Variable measurement and sample selection Before the Securities and Exchange Commission (SEC) reformed the executive compensation disclosure requirements regarding inside debt in 2006, it is very difficult to find out information related to the deferred compensation. Therefore, following Sundaram and Yermack (2007), the data set used in this paper for the period before 2006 consists of the pension data only, and ignores the minority of the cases for which deferred compensation data are available. Sundaram and Yermack (2007) calculate the actuarial present values of each CEO’s pension at the end of each fiscal year. They calculated the actuarial present value of a CEO’s pension by using the following formula – ∑_(n=max⠁ ¡(0,R-A))^(K-A)ââ€"’p(n)X/ã€â€"(1+d)ã€â€"^n Where X is the annual pension amount, R is the minimum retirement age, A is the CEO’s current age, p(n) is the probability that the CEO is alive n years in the future, collected separately for male and female CEOs from the actuarial tables published by the U.S Social Security Administration, d is the cost of long term debt, and K is the terminal year of the pension (maximum is set 120). Collecting pension data following the above procedure is time consuming. It involves checking each company’s proxy statement, and identifying the disclosed annual pension payments in matrix form, as required by the SEC.

Case Studies Of Temporary Shelters - 1201 Words

Case Studies of Temporary Shelters: This research on case studies synthesizes three existing temporary or â€Å"transitional† structures. These temporary structures are Global Village Shelters, Butterfly Houses, and Collapsible Woven shelter. This case studies analysis ways structurally sound shelters have been developed for migratory workers and homeless people in different geographical parts of the world. Some of the ideas have been implemented in the USA, Thailand, and Jordan. This research examines an orphanage shelter designed to both serve the purpose of a shelter and help children have fun on a swing tied to the roof of the shelter. All case studies have similar goal of building affordable temporary shelters for the homeless population. Global Village Shelter In 2004, Weyerhauser, a paper company manufactured the Global Village Shelter. The motive behind the manufacturing of the shelter was to create emergency or â€Å"transitional† shelters for people without a place to reside.

Mobile Technologies Free Essays

We are indeed living in a very fast-paced world. Everything seems to be found on the World Wide Web, communication is instant, and there are countless of technologies developed that would make our lives easier. These technologies, or most of them, aimed to make the world connected, so that communication is possible beyond distance, space, location or time. We will write a custom essay sample on Mobile Technologies or any similar topic only for you Order Now The history of communication would show us the developments and significance of communication in our everyday lives. The need for an efficient communication has led to the technologies that make communication faster. From messengers as a way to deliver the message in the old times to telegraphs and to telephones in the present time, communication has gone a long way. But the fact is that it didn’t stop there. Today, we can communicate through the vast choices of technologies such as cellular phones, pagers and computers. Further developments continue until today. These technologies have become mobile, meaning we can communicate with others, conduct business and be entertained on the go without being confined to one place, as is the case with desktops (Farooq Carroll n.d.). Thus, we call them mobile technologies. Many studies were conducted about different mobile technologies that can be offered to consumers. One thing those studies have in common is that they showed how important these technologies became, as shown by the demand for them. One significant aspect of mobile technologies is in the area of business. One does not really have to be in his office in front of the computer when conducting business. Even when he eats lunch, he can tie a deal with just a few clicks on his phone or palmtop. It is important to note that with the rise of these mobile technologies, certain things have changed. One example is how we conceptualize things, such as place, locality and physical presence. This paper will try to delve into the role and importance of these mobile technologies and how they affect our conceptualization of place, locality and physical presence. Mobile Technologies on Place and Locality Mobility is fundamentally associated with location (Farooq Carroll n.d.). The question that arises in connection with this is, how does location bring possibilities for the mobile user? Farooq and Carroll mentioned that location-based or place-based awareness for the users can be augmented by the use of Global Positioning System (GPS). The use of GPS will surely bring research possibilities and richer user interaction. According to the article â€Å"Locality in the Age of Virtual Transcendence,† the people’s experiences of place, locale in particular, are bound with the idea of distance. It adds that locale is a â€Å"human-centric concept† which exhibits a spatial relationship between presence – a mobile, for example – and a â€Å"perceivably stationary place.† Moreover, since humans cannot be at more than one location at a given time, this becomes an existential constraint. Today, however, we all experience transition into the virtual extensions of the physical world. Due to the technological advances, temporal and spatial distances have been overcome. In fact, two subjects can dwell in the same place in sound and image despite the physical distance. They can share a virtual space through avatars (Internet user’s representation of her or him) and can access physical spaces through webcams and satellite broadcasts. The article concluded that being at more than one location at the same time has risks. It says that man’s need to conquer distance and break the boundaries of locality may mean the loss of the possibility for transcendence (â€Å"Locality† n.d.). Meyrowitz (2004) agrees with this. He says that a person cannot occupy two places at the same time regardless of the sophistication the technologies offer. He adds that â€Å"the localness of experience is a constant.† The concept of locality persists in our everyday lives. Our basic needs must be â€Å"met locally.† We are also grateful for the local convenience stores when we need something. Meyrowitz (2004) mentions that although locality plays a role in the way we sense the world, those entities that we sense are not just local. Why? It’s because media have extended our perceptual field. He furthered that with the rise of mobile and immobile technologies, the people near us have less influence as they use technologies to interact with others who are more distant but still are local and accessible. Media have also influenced us in a way that we perceive our community as not just the community but one of the many communities where we could live. Our locality, we realize, is not the center of the universe, nor our physical surroundings the foundation of our experiences (Meyrowitz 2004). With the rise of mobile technologies, or those devices that we can carry around and still be connected to the world, we have conquered the concept of place. We can always communicate with our families or friends no matter where we are (as long as there is a signal). This is probably one of the advantages of these mobile technologies. Unlike desktop computers, radios or bulky devices, handheld and portable ones such as cellular phones and laptops and iPods can be carried around and some can even do business while riding the train. The new technologies have enable people to share information with others who are in different localities. Imagine that long ago, we couldn’t have reached the people who are in far localities in the same way we now do. Mobile, and immobile, technologies have enabled us to have access on our families and friends no matter where we are or where they are. In an article of O’Hara, Brown and Perry (2003), they believed that the concept of place in relation to mobility can afford various possibilities for â€Å"ongoing configuration of relationships with other people, and even for performing actions and for habitual action.† However, the configuration of place means more than just location. Technologies have important roles in making work possible for those mobile workers in different places, and devices such as mobile phone and networked laptop make these possible. The authors also mentioned that mobile workers can transform any place, be it restaurants, cafes or bars, into places of work. These leisure spaces become invaded by the mobile technologies. In fact, a testimony to this is the ring of the mobile phone in any of these places (O’Hara, Brown Perry 2003). Ito (n.d.) mentioned that â€Å"place and locality is a technology-enabled achievement.† This is probably because with technologies in our hands, place and locality is not a hindrance. We can communicate, do business, and be entertained in places that seemed impossible in the first place. Perlman (2005) added that technologies have made the Internet to be anywhere. In fact, they can even bring the Internet into the streets. When we look around us, we see people holding phones where they can access the Internet, or typing in a laptop. Perlman also said that people used to just view webpage, but now they can also create them. However, Farooq and Carroll (n.d.) countered by saying that users of mobile technologies have no access to peers or resources compared to desktop users. This is because mobile users are in a different contextual situation since everything within the environment has changed. The authors said that this usually leads to uncertainty, or heterogeneity. Moreover, mobile users of these technologies do not have much control over the configuration of their environment. Thus, they do not have much control on the way they manage work. People began to subscribe to these mobile technologies for whatever they’re worth. Today there are cellular phones that can help in tracking another person through location-awareness and presence. There are also phones that can receive information about that house you want to buy through a transmitter. Moreover, some phones today have built-in Global Positioning System (GPS) and outfitted with WiFi (Wireless Fidelity) technology. All of these are created to enhance communication or social networking or business (Smith Grubb 2004). Meyrowitz (2004) mentioned that through the electronic media (including the mobile technologies), people have become emotionally attached to certain places. Just think that long ago, when we are moving in another locality, we miss our old place along with its people and places and the experiences we have gathered there. But the media have helped us in a way that â€Å"we can now transport most of our nexus interactions with us wherever we go† (6). Smith and Grubb (2004) reported that consumers and businesses using location-aware computing will increase from 150,000 to 42 million in just three years. This was brought about by the 1996 FCC mandate that requires mobile carriers to find any subscriber making an emergency call to within 50 to 100 meters. They added that through location-awareness and presence, both of which enable a device to be geographically located, the way people use networked services will still change. Moreover, designers of such technologies are finding out ways that location-awareness, mobility and presence can further improve each service and application so that they can offer their users superior experience. Mobile Technologies on Physical Presence Through mobile technologies, one doesn’t really have to be with the person he communicates with just to talk with him or send him a message. This is one of the advantages offered by the mobile technologies. Today there are 3G (third generation) phones that enable someone to communicate with another while looking at that person on the phone. Several companies can also do a meeting while on different countries through a screen where they can see each other. It’s almost face to face. Farooq and Carroll (n.d.) believed that a sense of physical presence is associated with a common place wherein people meet and interact. But Harper, Goble and Pettitt (2004) argued that today, the virtual world tends to be more respected than the physical. They have mentioned that people are becoming too reliant on the ‘net’ because it is their gateway to other worlds or their way of communicating with remote people and a better form of self-expression. Moreover, the focus on the virtual distorts our perception in overestimating the importance of these technologies. As a result, the local environment becomes ignored when it comes to information giving. Harper, Goble and Pettitt (2004) added that the virtual and the physical must be connected because the latter is important to realize the full potential and importance of the virtual world. They also suggested that the ‘net’ and the mobile technologies must relate to the users’ physical location and real-world artifacts to be able to arrive at choices and decisions about what information will be useful or required. Smith and Grubb (2004) said that the introduction of the aspect of presence will bring changes in the way we use person-to-person communication media and will influence network service. For instance, when we know the location of a family member in advance, it eliminates the need to send a voice call when the reason for calling is to find out that information. Moreover, if we know the mood and activity of that person, we can determine the method of communication that is appropriate. Another example is that, if we want to call a friend just for a friendly chat, it would be better to know first if he is not busy or in a bad mood. In the same way, if I need to contact an associate about an urgent business decision, I would like for him to know this urgency so that he can let me know what he thinks. Farooq and Carroll (n.d.) commented that handheld devices are now engrained in our everyday lives. But that would mean we should consider the existing application and how the standard will change with the emerging mobile technologies. They added that handheld technologies, which are also mobile in a sense, can create even better interactions and consequences for different users, whether they are in their homes or outside. This just shows that the addition of mobility to the various technological devices will supply more channels of communication that are beyond the exchange of information. Rheingold (2005), along with some friends, has interviewed several mobile technologies users, preferably those who use telephones. Their survey showed that the people of Shibuya, particularly the teenagers, were very much into sending text messages and ring tones and logos. In fact, they are called â€Å"the thumb tribe† (Rheingold 2005). The article also showed that the advent of mobile phones in Japan has freed youth in one way or another. It was mentioned that they are no longer constrained by the landline shared by inquisitive family members. Mobile phones have offered youth privacy, something the landline cannot give them. This is just one of the reasons why the mobile phones started an intergenerational power shift in the country (Rheingold 2005). More and more developments will arise that would further affect how we conceptualize place, locality and physical presence. One thing is for sure: these technological developments are there to help us in making our lives easier and giving us richer experiences. However, as these technological advancements cannot be avoided and must be embraced to realize their full potential, users must bear in mind that they must still appreciate and give importance to the things that would somehow affect them. It is still better to go visit and see our friends and families no matter how far they are and despite that mobile phone in our pockets. And it is still better to treasure the places and the locality that have been a part of our lives. References The Beginnings of Communication. N.d. Swinburne University of Technology. Farooq, U.
