Catch A Yawn
A trick in every girl's handbook: If you want to know if someone is checking you out, yawn and check to see who, if anyone, yawns back. While we may be using the contagious phenomenon of yawning to our advantage, the age-old question still lingers on - why, in fact, is yawning contagious? Plausible explanations range from historic origins to muscular requirements. However, one answer that encompasses all other questions about the cause and traits of yawning has yet to be found.
First, let's tackle the question of why we yawn. An evolutional/psychological theory has claimed that yawning was once used as a non-verbal form of communication to synchronize group behavior among animals (9). For example, the leader of a pack of wolves would yawn to set a certain mood or signal a change of activity. Humans also being group-oriented animals may have assimilated to this form of agreement. In the same way that one pumped up team member can influence the level of aggression and team-spirit of an entire team, one yawning client can also affect the mood of sales-pitch meeting. Another good example of synchronization among humans is if a group is sitting around a campfire and the leader yawns, it most likely will act as a signal to the others that it may be time to call it a night.
Yawning is commonly perceived to be a sign of boredom or tiredness. Dr. Robert Provine, known as the yawn-expert from the University of Maryland, performed a study on 17-19 year old students to test this perception. In comparison to a group of students who watched music videos for 30 minutes, a group who watched an uninteresting color test bar pattern for 30 minutes yawned more (10). Dr. Provine also suggested that yawning is like stretching (5). Much like stretching, blood pressure and heart rate can be increased just by yawning. Perhaps animals yawn instinctively when bored or tired to get their blood pumping so that they may be physically stimulated to move or seek a new activity. But then why is it that we yawn after waking up? If we yawn after waking as a physical prompt to become active that's one thing. But yawning as a sign of tiredness can be ruled out if we yawn after waking from a restful sleep. Maybe a study could be done in which a comparison could be made between the hours of sleep and the occurrence of yawning when waking.
Normalization is significantly outlined through healthful living styles, positive word choice, and regular development pace in children. In Never Let Me Go, Miss Lucy, who is a guardian
West Virginia has a diverse history and strong record of struggle. From the original settlers to the current citizens, they have always found a way to survive and succeed (Wilson, 1990). The economic struggles of West Virginia have been due to the outsourcing of resources, income, capital, and information for the past 100 years (Cometti, 1966). This has led to reliance on the state and federal government to provide subsidies, and other welfare programs to help the citizens of the area feed, clothe, and shelter their selves (Erickson, 1986). Roughly, since the Kennedy administration’s increase of spending on food stamps and other assistance programs, and the correlated dwindling down of coal mining in the state, the adoption of citizens utilizing assistance programs has increased exponentially (Greenberg. 1969). Historically, democratic representatives display more favor in continuing or increasing these expenditures for assistance programs.
To start off, 3D printing is form of additive manufacturing. It works by building or “printing” a model one layer at time and works from the bottom up. The process starts off by applying a layer of powder onto a platform to which, depending on the printer, sprays liquid binder and a bonding agent as a mean to solidify and strengthen the powder. This process is repeated until finished and can take anywhere from a few hours to a few days. Yet, in order to be able to transform a digital file into a tangible, physical object, the following are required: 1) a design using CAD software, 2) to save the file as a STL, and 3) a 3D printer of some sort.
Technological determinism “sees technology as the cause of cultural and social change” (Morris, 2013). Within technological determinism, there are two different types. Hard technological determinism is “an oversimplified, cause and effect explanation for social change” (Johnson, 2013). Soft technological determinism views “technology is one of many social factors that drive social change” (Johnson, 2013). Viewing the Internet as one of the many factors in shaping social change is a technological determinist view. Young a...
In the United States of America, human trafficking and prostitution is illegal. Human trafficking is the practice of procuring or trading in human beings for the purpose of prostitution, forced labor, or other forms of exploitation (Human trafficking). The buying and selling of children began after slavery ended in the 1860’s, and since then it has become more widespread. The government ruled the act of selling people for profit unconstitutional because it was a violation of human rights. In the past, our government did not do all they could to protect the people from trafficking, currently, there are laws being passed in attempt to eradicate it and in the future, the government should work harder to end human trafficking and prostitution in the United States.

3D printers have been linked all the way back to 1952 as an adaption of Computer Numeric Controlled machines which were early computers wired to milling machines (Martin Bowden, & Merrill, 2014, 31). The milling machines would start with one big solid piece of material and then use lasers and water-jet cutting to shave off material until the desired result was achieved (Martin et al., 2014, 31). This is quite the difference from 3D printers nowadays because the more modern printers print out material instead of shaving off material. These machines were used because the reliability and accuracy of a
The process starts with a concept or idea.(Mashable) The first stage of 3D printing is planning out this concept with either computer aided design or animation modeling software. There are tons of programs out there today with these capabilities. Google SketchUp for example is known for being easy to use.(3ders) Using some easy tools that can be learned quickly, edges and faces can come together to make very intricate models. It can even be used with Google Earth. All those models of the world in that software are made in what is basically the same process digitally. Blender is the free 3D creation program that exists for the needs of major operating systems.(3ders) It is a high end software containing features that are much more capable than Google SketchUp. Tinkercad is a newer way of creating designs for 3D printers and works slightly faster than the others.(3ders) Containing only three simple tools, it’s effectiveness for creating models is among the best..
Technology makes people easier to connect with others but more and more connections make people have no room to have intimacy relationships with others. Technology changes people’s mainstream idea and makes people have no time to enjoy or keep those intimacy relationships. However, it can also point out that if people are trying to live in a slow-style life and keep their inner minds, they will finally find the happiness of their intimacy relationships with their friends and families.
In order to understand the role of modern technology on relationships, it is essential to note that there are many types of relationships mainly formal and informal. Formal relationships are those that req...
...ained briefly in this report. In conclusion, 3D printers will be used to begin in many areas. Despite concerns of users and governments about gun producing, many companies are already using the technology to repeatedly produce complex components of their design. As I mention, medical and automotive and aviation industries is commonly used techniques for develop their design. As 3D printers become more affordable, the small scale manufacturing will impossible to avoid use this technology which obtain them a change against large supply manufacturer for many types of product. Consumer units for home use will even become feasible, allowing end users to simply download a design for the product which they require and print it out. Because of its advantages, it will became more popular in recent year. I guess that everybody will have a 3D printer in future in their home.
Why go to stores and spend lots of money buying toys, jewelry, cups and many other plastic utilities when you can only press one button and print them out for yourself. This futuristic idea is not only innovating the scientific and technological world, but it is also innovating modern day households. The possibilities of 3D printing are extremely captivating, making this one of the most exciting innovations in recent times. 3D printing, also known as additive manufacturing, makes three-dimensional solid objects from a digital model or command. To picture how this process works, 3D printers use an additive process, where adding layers of a successive material creates an object. Traditional machines, however, uses a subtractive process by cutting or removing a specific material to shape the desired object. This mean of production can be known as a “democratization” of manufacturing since it promises a huge potential for creativity to let loose, offering a realistic possibility for everyone to produce almost any type of object. With over one-hundred different materials a 3D printer can print in, the possibilities of this new type of technology are marveling. For this reason, this new technological revolution demonstrates great potential because we will be able to use it as a household level of production, it will foster economic growth and it will be of great interest to the public.
3D printing is thought as desktop fabrication or additive producing, it's a prototyping method whereby a true object is formed from a 3D style. The digital 3D-model is saved in STL format then sent to a 3D printer. The 3D printer then prints the look layer by layer and forms a true object. Not like of the common printers. On a 3D printer the item is written by 3 dimensions. A 3D model is constructed up layer by layer. Thus the entire method is termed fast prototyping, or 3D printing.
Sleeping is a simple yet complex process that individuals go through every day. During sleep, a person will go through a total of five stages of sleep. These stages are known as stage 1, stage 2, stage 3, stage 4, and stage 5/REM sleep. http://psychcentral.com provides a good explanation as to what happens during these stages of sleep. During stage one a person is in light sleep mode, meaning that their body temperature and heart rate pretty much stay the same as if they were awake. Their brain also produces brain waves known as theta waves during this s...
The big question about the 3D printer is how to make an object once a 3D printer is obtained. Crafting anything with the 3D printer is quite simple. In order to make a model that a 3D printer can read, one needs to have a computer-aided design (CAD) software. Because CADs use combinations of shapes and specific measurements a good knowledge of geometry is required (Hoffman). Next, the materials needed for the object must be acquired. 3D printing uses a method that melts down the material used to create the object you want (Kovac). Therefore, combustible items such as wood, pape...
