Time displacement - Wikipedia

Time displacement hypothesisThis article discusses a concept in sociology. For the concept in physics, see time dilation. Time displacement in sociology refers to the idea that new forms of activities may replace older ones. New activities that cause time displacement are usually technology-based, most common are the information and communication. All organisms have certain habitable zones delimited by physical parameters outside of which they cannot persist by themselves. This can be a result of parasitism and predation, or of gross physical stresses. Within the habitable zone long established species usually exhibit a typical average density with generally narrow fluctuations. Species may be designated as rare, common or abundant. Ecologists have paid most attention to fluctuations of abundance, while too little thought has been given to reasons for the rarity or absence of a species altogether. Such scarcity is especially intriguing when physical conditions seem optimum. Some species reach these areas from time to time, but they do not persist. Extinction will often occur in a particular area when residence had been temporarily established. De Bach (1966) discussed the competitive displacement "principle." Various synonyms for this idea are Gause's Law (1934), Grinnell's Axiom (1943), the Volterra-Gause Principle (Hutchinson 1957, 1960), and the Competitive Exclusion Principle (Hardin 1960). Next

Peacock and Wiseman's Displacement Effect - SSRN papers

Time displacement hypothesisAbstract Although Peacock and Wiseman's "displacement effect" is frequently cited as an explanation of increases in government spending over time, the theory has so far been inadequately tested. In this paper four versions of the hypothesis are identified, and earlier empirical tests are reviewed and found efficient. A new. A new study argues that while a lot has been said by scientists and paediatricians about the possible dangers of teenagers spending time on digital devices or computers, there is little robust evidence to back up their claims. The researchers say they are the first to systematically test for links between well-being and screen time measured continuously, separately for different digital activities and days of the week. They have proposed the Goldilocks theory: that there is a point between low and high use of technology that is ‘just right’ for teenagers when their sense of wellbeing is boosted by having ‘moderate’ amounts of screen time. The researchers suggest this may be because digital connectivity can enhance creativity, communication skills and development. Their findings also suggests that the relationship between screen time and well-being is weak at best, even when young people overuse their digital devices. The paper is published in the journal, Psychological Science. Using a well-established self-report measure of mental well-being, researchers from Oxford and Cardiff universities analysed how 120,000 15 year olds in Britain felt after using digital technology and how much time they spent on different devices. Nearly all (99.9%) of the participating adolescents reported spending time using at least one type of digital technology on a daily basis. Next

Television Use and Social Capital Testing Putnam's Time.

Time displacement hypothesisJun 22, 2011. Robert Putnam 1995a, 19956 charged that television is the driving force behind the decline in social capital in America. He argued that television viewing has privatized our leisure time, thus inhibiting participation outside the home. However, Putnam's time displacement hypothesis never has been tested. Amy is aroused by Penny's ex-boyfriend Zack Johnson and is unfamiliar with the feeling. Sheldon thinks she has contracted an alien parasite. Meanwhile, Howard and Raj battle out who is the hero and who is the sidekick in their friendship. While eating their take-out dinner around the coffee table, Sheldon complains that the next person who ate with their mouth full will be put to death. This comment is followed later by Sheldon asking what everyone thought the best number was. Not 5,318,008, as suggested by Raj, since upside-down on a calculator it spells “Boobies”. Next

Displacing the Displacement Hypothesis? Does the Internet Really.

Time displacement hypothesisThis displacement hypothesis has been tested not only on time spent on specific media e.g. Ha & Fang, 2012; Lee & Leung, 2008 but also on how much households spend on mass communication consumption e.g. McCombs & Nolan, 1992; Son & McCombs, 1993. The literature, however, is not unanimous in finding that. Time displacement in sociology refers to the idea that new forms of activities may replace older ones. New activities that cause time displacement are usually technology-based, most common are the information and communication technologies such as Internet and television. Those technologies are seen as responsible for declines of previously more common activities such as in- and out-of-home socializing, work, and even personal care and sleep. For example, Internet users may spend time online using it as a substitute of other activities that served similar function(s) (watching television, reading printed media, face to face interaction, etc.). Internet is not the first technology to result in time displacement. Next

The metallic elements, most sulfides, and some oxides belong in this category. Submetallic - Describes a mineral that is opaque to nearly opaque and reflects well. Thin splinters or sections of submetallic minerals are translucent. Vitreous - This luster accounts for roughly 70 percent of all minerals. Minerals with a vitreous luster have reflective properties similar to glass. Most of the silicates, carbonates, phosphates, sulfates, halides, and hydroxides have a vitreous luster. Adamantine - Transparent to translucent minerals with a high refractive index yield an adamantine luster, meaning they display extraordinary brilliance and shine. Next

Nonverbal Communication is a type of communication that occurs without the use of words and is continuous. This includes the act of communicating with one another via body language or other symbolism to convey meanings. It can be communicated through gestures, touch, body language, posture, facial expression, and eye contact. Non-verbal communication is different from person to person and especially from one culture to another. For example, if you are a Foreigner and you are traveling to Japan but you don’t speak Japanese, you don’t have a translator either or a dictionary and you can only use non-verbal communication to communicate with people, you go to a restaurant and order food by pointing at something.

Questions of Temporal and Spatial Displacement in Animal Cognition

Time displacement hypothesisThis chapter examines whether these displacement abilities of humans can be found in animals. With regard to the temporal displacement question, it considers the hypothesis that animals are “stuck in time.” A parallel “stuck-in-space” hypothesis may be advanced regarding spatial displacement. This chapter reviews some. ) hypothesis postulates an inverted-U-shaped relationship between different pollutants and per capita income, i.e., environmental pressure increases up to a certain level as income goes up; after that, it decreases. An EKC actually reveals how a technically specified measurement of environmental quality changes as the fortunes of a country change. A sizeable literature on EKC has grown in recent period. The common point of all the studies is the assertion that the environmental quality deteriorates at the early stages of economic development/growth and subsequently improves at the later stages. In other words, environmental pressure increases faster than income at early stages of development and slows down relative to GDP growth at higher income levels. This paper reviews some theoretical developments and empirical studies dealing with EKC phenomenon. Possible explanations for this EKC are seen in (i) the progress of economic development, from clean agrarian economy to polluting industrial economy to clean service economy; (ii) tendency of people with higher income having higher preference for environmental quality, etc. Evidence of the existence of the EKC has been questioned from several corners.

The Displacement Hypothesis — a tangentially-related research.

Time displacement hypothesisMar 9, 2010. The Displacement Hypothesis says that one activity can displace another activity. In the following research by Robert Weis and Brittany Cerankosky, boys given video games 1 did worse in school, 2 spent less time in other after-school activities, 3 had more behavioral problems, and 4 had lower. A quasi-experimental design is one that looks a bit like an experimental design but lacks the key ingredient -- random assignment. My mentor, Don Campbell, often referred to them as "queasy" experiments because they give the experimental purists a queasy feeling. With respect to internal validity, they often appear to be inferior to randomized experiments. But there is something compelling about these designs; taken as a group, they are easily more frequently implemented than their randomized cousins. I'm not going to try to cover the quasi-experimental designs comprehensively. Instead, I'll present two of the classic quasi-experimental designs in some detail and show how we analyze them. Probably the most commonly used quasi-experimental design (and it may be the most commonly used of all designs) is the nonequivalent groups design. In its simplest form it requires a pretest and posttest for a treated and comparison group. Next

Assume that a body of mass m is dropped from a great height above the surface of the earth. Our task is to answer the following Important Question: How far does the object fall in the first 100 seconds? We assume that there are two forces affecting the vertical descent of the object: gravity and air resistance. Here's what we are going to do: Introduce some new calculus magic to answer the important question---this material is discussed in Section 5.1 of your text; it involves the introduction of a rectangle approximation technique to estimate the area under the speed graph. It was Galileo who offered the hypothesis that the acceleration due to gravity near the Earth's surface is essentially constant. Newton's law, force = mass x acceleration, then implies that . Let s(t) be the downward speed of the object t seconds after it is dropped, measured in m/sec. One hypothesis governing air resistance is the following: Look at it this way, as the object moves through the air, it collides with air molecules, displacing them as it falls. The faster the object moves, the more collisions and so the greater the overall force due to air resistance. The positive constant k is the constant of proportionality and its units are kg/sec; the numerical value of k depends upon the shape of the object being dropped and the density of the atmosphere. An alternative hypothesis is that the force due to air resistance is proportional to the square of the speed..might be more reasonable, for example, at very high speeds. We now see that the total force acting on the falling object at any time t is given by Now comes the first real conclusion involving calculus. Remember that acceleration is the rate of change of speed. Next

Time displacement hypothesisPeacock and Wiseman/ in a notable study of the historical patterns of the British government expenditure over the 1890-1955 period, formulated the 'displacement hypothesis' that may help to explain the time profile of government expenditure growth also in other countries and at other times. Peacock and Wiseman, 196lJ. Crust displacement was a hypothesis put forward by Charles Hapgood (1904—1982). In short, it asserts that sometimes the Earth spins really fast and the continents rearrange. Hapgood believed that this happened relatively recently and was what caused the continent Mu to disappear. Hapgood's theory stands in stark contrast to the theory of plate tectonics that eventually became accepted. It is the progenitor to the somewhat more cataclysmic idea of a "pole shift". Hapgood was an American historian working towards his Ph D on the French Revolution when the Great Depression dried up his funding. After several stints in different military and federal agencies during World War II, he settled down and taught history at Springfield College in Massachusetts until he was fatally hit by a car in 1982. Hapgood wrote a number of books detailing his theory including The Earth's Shifting Crust (1958), Maps of the Ancient Sea Kings (1966), and The Path of the Pole (1970). Next

Children's Creativity and Television Use - Stimulation Hypothesis.

Time displacement hypothesisThe displacement hypothesis argues that children spend a considerable portion of their free time watching television at the expense of other leisure activities. In the case of imaginative play, the displacement hypothesis assumes that television viewing takes up time that could otherwise be spent on imaginative play. If a nail and a toothpick are simultaneously dropped from the same height, they do not reach the ground at exactly the same instant. (Try it with these or similar objects.) In Galileo's attack on the Aristotelian cosmology, few details were actually new. However, his approach and his findings together provided the first coherent presentation of the science of motion. Galileo realized that, out of all the observable motions in nature, free-fall motion is the key to the understanding of all motions of all bodies. To decide which is the key phenomenon to study is the real gift of genius. But Galileo is also in many ways typical of scientists in general. His approach to the problem of motion makes a good "case" to be used in the following sections as an opportunity to discuss strategies of inquiry that are still used in science. These are some of the reasons why we study in detail Galileo's attack on the problem of free fall. Next

Internet and Displacement Effect Children's Media Use and.

Time displacement hypothesisTime spent on various media becomes an issue since the underlying assumption is that individuals have a limited amount of time, which can be seen as a kind of social. The literature shows that the displacement hypothesis has conceptual and methodological problems, and the answer is far from being conclusive Mutz. How should American teens spend their leisure time? I recently asked* American adults this question, after explaining that the typical teen enjoys approximately five hours of leisure time each weekday. The activity with the highest response, irrespective of race, education, and other demographic factors, was reading. What prompts a teen to choose reading over a different activity during her leisure time? Reading will hold little appeal if a student has trouble decoding or has problems with comprehension. Adults thought teens ought to spend about an hour and 15 minutes reading for pleasure each day. But what if a student is a fluent decoder and generally understands texts that she tackles? What might be done to motivate her, both at school and at home? In a nutshell, the problem of motivation is this: we want the student to do something we think is important, but she chooses not to do it. That is, of course, not an unusual problem in classrooms, and a potential motivator is some kind of negative consequence. A student who doesn’t do the required work will receive low grades, or perhaps feel guilty for disappointing the teacher, or feel embarrassed should the failure become public. But by the time a student is in middle school, these blades have long lost their edge. Next

He summarised and extended the work of his predecessors in his five-volume Mécanique Céleste (Celestial Mechanics) (1799–1825). This work translated the geometric study of classical mechanics to one based on calculus, opening up a broader range of problems. In statistics, the Bayesian interpretation of probability was developed mainly by Laplace. Laplace formulated Laplace's equation, and pioneered the Laplace transform which appears in many branches of mathematical physics, a field that he took a leading role in forming. The Laplacian differential operator, widely used in mathematics, is also named after him. He restated and developed the nebular hypothesis of the origin of the Solar System and was one of the first scientists to postulate the existence of black holes and the notion of gravitational collapse. Laplace is remembered as one of the greatest scientists of all time. Next

The suggested collection of mathematical folklore might be enjoyable for mathematicians and for students because every joke contains a portion of truth or lie about our profession. The selected jokes and sayings contain something essential about mathematics, the mathematical way of thinking, or mathematical pop-culture. We are concerned that publication of sacral lecture jokes may endanger the respect to math. Our excuse for this risky ethnographic research is that the majority of the jokes already exists on the Internet. Sometimes, people tend to attribute the jokes either to their beloved teachers (Peter Lax is so far the champion) or to legendary figures as Norbert Wiener or Paul Erdos; similarly, physical jokes are attributed to Albert Einstein or Niels Bohr and geometrical theorems - to Euclid.

Partner Phubbing How Cell Phones Impact. - Baylor University

Time displacement hypothesisMar 1, 2017. The displacement hypothesis helps to explain the deleterious effects of Pphubbing on relationship satisfaction. According to the displacement hypothesis, time spent on cell phones may reduce displace meaningful interactions with one's significant other. Conflict over cell phone use may then arise not. We often hear it said that people who use Facebook suffer deteriorating social relationships due to their excessive online preoccupation. However, we know from previous research that people use social media for different reasons, reflecting their “Facebook personality.” The fact remains that a common perception of Facebook users is that, over time, their online habits cause their real-life social relationships to deteriorate. According to the displacement hypothesis, the time that people spend on with their virtual social partners displaces the time they spend with their real ones in Ft F (“face to face”) interaction. If you’re spending 3 or 4 hours a day on Facebook, you won’t have enough time to invest in your relationships with your loved ones and friends. Furthermore, if you’re in your online world, the displacement hypothesis argues, you’ll have less of the time and incentive you need to meet new people who might become your friends or loved ones. As reviewed by University of Wisconsin-Milwaukee communications researcher Hayeon Song and colleagues (2014), prior evidence has suggested that when people spend a great deal of time on Facebook, their social networks shrink. They tend to retreat within themselves, eventually becoming depressed, lonely, and dissatisfied with their lives. point out, there’s also evidence to support the social augmentation hypothesis.

Time-Displacement and Efficiency Journalism in the Digital Age

Time displacement hypothesisThe Time-Displacement Hypothesis is based on the idea that time is zero-sum. As Lars Willnat explains it, “Because there are only 24 hours in a day, time spent on one activity must be traded off against time spent on other activities.” On the other hand the Efficiency Hypothesis argues that the internet increases efficiency so. It is hypothesized that the object that is dropped will endure gradual change acceleration in acceleration. The acceleration for the object in the velocity time graph will be gravity (9.81 m/s^2). And the velocity time graph will be a straight line. I used the table on the given lab sheet to design a table for my results. Me and my lab partners clamped a recording timer in a vertical position above the floor as shown in figure 1. We used masking tape to attach a 50g mass to the end of the 121cm recording tape. We threaded the recording tape through the timer and held the upper end vertical to minimize the friction between the timer and the tape. We started the timer and then released the 50g mass. Next

Our study of 1-dimensional kinematics has been concerned with the multiple means by which the motion of objects can be represented. Such means include the use of words, the use of diagrams, the use of numbers, the use of equations, and the use of graphs. As we will learn, the specific features of the motion of objects are demonstrated by the shape and the slope of the lines on a position vs. The first part of this lesson involves a study of the relationship between the shape of a p-t graph and the motion of the object. To begin, consider a car moving with a If the position-time data for such a car were graphed, then the resulting graph would look like the graph at the right.

Assessing the displacement effects of the Internet - CUHK

Time displacement hypothesisPrinciple of relative constancy also applies in this instance, but the reduction of time and expenditure may be seen only in non-media activities or media that serve different needs. For media that serve similar needs, no displacement is to be expected under the user-centric approach. A ''more-more'' hypothesis underlies the. Probes the complicated relationship between loneliness and social internet use. Psychological science researcher Rebecca Nowland at the University of Manchester and colleagues from the University of Chicago performed a literature review of studies focused on the topic and found that social internet use (using platforms like Facebook and Twitter, for example) is associated with loneliness, but the relationship is complex. In their article, Nowland and colleagues attempt to reconcile a number of contradictory study results to pinpoint the relationship between social internet use and loneliness. For example, posting status updates on Facebook reduced feelings of loneliness over a 1-week period. A separate study found that over a 3-month period, posting frequently decreased feelings of to individual members of one’s social network. The researchers note that a lot of the available data comes from cross-sectional studies that measure internet use and loneliness at a single point in time. Studies that follow participants longitudinally are generally required for testing causation. Prior research has led to two major hypotheses to describe the relationship between loneliness and social technology use. Next

Among respondents 59% people agree that they use the internet to renew online contacts with old friends. Whereas only 25% respondents strongly agree they use the internet to intensify online contacts with their relatives. It targeted 440 respondents and got response from 400 (200 male, 200 female) having demographic characteristics like, age, gender, education and income of respondents. Next

Information technology and social time displacement - CiteSeerX

Time displacement hypothesisActivities are most affected by the Internet is through the 24-hour time-diary studies, in which all daily activity is. communication behaviors rather than to displace behavior – which seems to be the case for television as. These above results shape one's hypotheses and expectations, away from simple time displacement. We used geological field studies and diatom biostratigraphy to test a published hypothesis that Neogene marine siliceous strata in the Maricopa and Parkfield areas, located on opposite sides of the San Andreas Fault, were formerly contiguous and then were displaced by about 80–130 kilometers (km) of right-lateral slip along the fault. In the Maricopa area on the northeast side of the San Andreas Fault, the upper Miocene Bitterwater Creek Shale consists of hard, siliceous shale with dolomitic concretions and turbidite sandstone interbeds. Diatom assemblages indicate that the Bitterwater Creek Shale was deposited about 8.0–6.7 million years before present (Ma) at the same time as the uppermost part of the Monterey Formation in parts of coastal California. In the Parkfield area on the southwest side of the San Andreas Fault, the upper Miocene Pancho Rico Formation consists of soft to indurated mudstone and siltstone and fossiliferous, bioturbated sandstone. Diatom assemblages from the Pancho Rico indicate deposition about 6.7–5.7 Ma (latest Miocene), younger than the Bitterwater Creek Shale and at about the same time as parts of the Sisquoc Formation and Purisima Formation in coastal California. Our results show that the Bitterwater Creek Shale and Pancho Rico Formation are lithologically unlike and of different ages and therefore do not constitute a cross-fault tie that can be used to estimate rightlateral displacement along the San Andreas Fault.

Geological Survey Scientific Investigations Report 2017–5125, 26 p., https://doi.org/10.3133/sir20175125. In the Maricopa area northeast of the San Andreas Fault, the Bitterwater Creek Shale overlies conglomeratic fan-delta deposits of the upper Miocene Santa Margarita Formation, which in turn overlie siliceous shale of the Miocene Monterey Formation from which we obtained a diatom assemblage dated at about 10.0–9.3 Ma.

Previous investigations noted that the Santa Margarita Formation in the Maricopa area contains granitic and metamorphic clasts derived from sources in the northern Gabilan Range, on the opposite side of the San Andreas Fault, that have moved relatively northwestward by 254 ± 5 km of right-lateral displacement along the fault.
