A Brief History of the Selfie

Selfie is the slang term for self-portrait, a photograph you take of yourself, usually taken using a mirror or with a camera held at arms length. The act of taking and sharing selfies has become widely popular due to digital cameras, the internet, the ubiquity of social media platforms like Facebook and, of course, because of peoples endless fascination with their own image. The word selfie was even chosen as the Word of the Year in 2013 by the Oxford English Dictionary, which has the following entry for the word: A photograph that one has taken of oneself, typically with a smartphone or webcam and uploaded to a social media website. History of the Self Portrait So who took the first selfie? In discussing the invention of the first selfie, we have to first pay homage to the film camera and the early history of photography. In photography, self-portraits were taking place long before the invention of Facebook and smartphones. One example is American photographer Robert Cornelius, who took a self portrait daguerreotype (first practical process of photography) of himself in 1839. The image is also considered one of the earliest photographs of a person. In 1914, 13-year-old Russian Grand Duchess Anastasia Nikolaevna took a self-portrait using a Kodak Brownie box camera (invented in 1900) and sent the photograph to a friend with the following note I took this picture of myself looking at the mirror. It was very hard as my hands were trembling. Nikolaevna appears to have been the first teenager to take a selfie. So Who Invented the First Selfie?   Australia has laid claim to inventing the modern-day selfie. In September 2001, a group of Australians created a website and uploaded the first digital self-portraits onto the internet. On September 13, 2002, the first recorded published use of the term selfie to describe a self-portrait photograph occurred on the Australian internet forum (ABC Online). The anonymous poster wrote the following, along with posting a selfie of himself: Um, drunk at a mates 21st, I tripped over and landed lip first (with front teeth coming a very close second) on a set of steps. I had a hole about 1cm long right through my bottom lip. And sorry about the focus, it was a selfie. A Hollywood cameraman named Lester Wisbrod claims he is the first person to take celebrity selfies, (a self-taken photo of himself and a celebrity) and has been doing so since 1981. Medical authorities have begun to associate the taking of too many selfies as a potentially unhealthy sign of mental health issues. Take the case of 19-year-old Danny Bowman, who attempted suicide after failing to take what he considered the perfect selfie. Bowman was spending most of his waking hours taking hundreds of selfies every day, losing weight and dropping out of school in the process. Becoming obsessed with taking selfies is often a sign of body dysmorphic disorder, an anxiety disorder about personal appearance. Danny Bowman was diagnosed with this condition.

Gender, Gender And Gender Roles - 1829 Words

Gender socialization often begins early once parents are shown the sex of their child; from then on, baby showers are planned according to gender â€Å"appropriate† colors, which are often pink for girls and blue for boys. Even differences in how children are spoke to can be picked up easily in Western cultures. Girls are called pretty and sweet, whereas boys are handsome and strong. Ultimately, the way children learn to identify with their gender culture is in part due to not only family and friends, media, schools, and religion, but also from the toys that may inexplicitly advertise gender expectations. Gender-typed toys may be bought for children as a way for parents to encourage and reinforce gender-appropriate behaviors. However, recent debates have engulfed toy manufacturers and major retailers, which has brought about changes in toy design and marketing in an effort to make reflect more realistic and gender neutral options. Gender Differences Gender should not be intertwined with the term sex, which refers to the physical differences in individuals. Instead, gender is the idea of being male or female, and it is well understood by the time children reach the preschool years. Differences in gender become more pronounced as children age, and societal expectations are reinforced by parents and peers.

Materials Scien ce and Engineering involves the survey of the construction. belongingss and behavior of all stuffs. the development of procedures to fabricate utile merchandises from them. and research into recycling and environmentally friendly disposal. The basic edifice block of all affair is the atom and there are 94 different types that occur of course on Earth. These are ‘the elements’ and include H. O. C. Si. Fe. Cu. and aluminum. All stuffs are made up of these atomic edifice blocks but differ in their microstructure: the types of atom they contain. the form in which the atoms are arranged and the manner in which the atoms are joined together. The cardinal construct in Materials Science and Engineering is that the belongingss and behavior of every stuff is dependent on its microstructure. and that microstructure can be controlled by the manner in which the stuff is made and processed. Materials Scientists test the mechanical. physical. chemical and electrical belongingss of stuffs and research how these belongingss depend on the microstructures they engineer and observe utilizing high powered microscopes. Materials Engineers apply this cognition to choose the most appropriate stuff and fabrication procedure for any given application. to foretell how a constituent will execute in service. and to look into how and why stuffs fail. The technological progresss that have transformed our universe over the last 20 old ages have been founded on developments in Materials Science and Engineering. Materials are germinating faster today than at any clip in history ; enabling applied scientists to better the public presentation of bing merchandises and to develop advanced engineerings that will heighten every facet of our lives. Materials Science and Engineering has become a cardinal subject in the competitory planetary economic system and is recognised as one of the proficient subjects with the most exciting calling chances. Glossary: Structure – how the atoms fit together. For crystalline stuffs. so this involves the size and form of the crystals ( normally called grains ) . Microstructure – construction on a little graduated table so that a microscope is needed to see it. Properties – measured behavior. such as strength. electrical conduction. stiffness or coloring material Processing – altering the form or belongingss of a piece of stuff. for case by heating it. turn overing it or stretching it.

Through this experiment, we might be able to find ways of increasing the growth of the plants found in our garden. Scope and Limitations The researchers will try to determine whether different substances (water with salt, sugar, powdered milk or water only) will affect the growth of the plants. They will be allotting 2 months for us to see if the water mixtures namely water with salt, sugar, and powdered milk can affect the growth of plants. The plants in trial 1 will be receiving enough sunlight while trial 2 will not be receiving enough sunlight, watered equally and have a control set up so that we can compare the results after the time allotted for the experiment. They will not be spending as much because most of the products they will be using are found at home. They will be having a PH. 500 budget to buy materials that we will need but couldnt find them at our houses. The Independent variable will Include the plants we used In testing, water with the mixtures. The dependent variable will be the result of dealing with or experimenting nee Inaepenaenvexperlmental variable. In tens case, It will De ten amount AT sugar, salt, and powdered milk that they will mix with the water to see if these will affect the Peachy plant we will be using for our experiment. Their controlled variable will consist of the peachy plant and water. Review of Related Literature Tap Water on Plants Tap water is good for plants that need water with chlorine in it, spring water is good for carnivorous plants in order for them to grow, and bottled water is good for plants like cactuses that need mineral water to grow. Sugar on Plants Plants require three essentials, light, water and nutrients to thrive and produce optimum yield. Plants naturally produce sugars, such as glucose and sucrose. These sugars are needed to produce energy, promote growth and aide in the processes of respiration and transpiration. Sugar can also be introduced to a plant through watering to enhance growth and production. Sugar, in moderation, is not harmful to plants. If the amount of sugar in the soil becomes too high, this promotes a higher incidence of fungi and bacteria. A typical fungus that thrives on sugar is yeast. In a study at University of Southern California, here groups of bean plants were watered with different degrees of sugar water (O g, 25 g and 50 g solutions). The group of plants which had been watered with the 50 g sugar/water solution was not only the largest and strongest of the plants, they were also the healthiest and highest yielding plants. Effect of Salt Concentration on Plant Growth Many western farmers believe that soil alkali is more detrimental to crop growth during the hot weather than during the cooler seasons of the year. Other agricultural workers have noted that damage to crops due to alkali (soil salinity) is more serious in he hot interior valleys than along the coast where the climate is more moderate. It is not definitely known whether or not soil salinity concentrations are comparable between different seasons of the year or between respective areas. Yet, information on this question is pertinent to the development of management practices which would aid in ameliorating soil salinity conditions at different seasons of the year and under different climatic conditions. The results obtained in this study show that* most crops are injured by salt to a greater extent in warm than cool climates. The Effect of Water Impurities on Plant Growth The purpose of this experiment was to determine the effect of water impurities on the growth of plants. Each plant was put near a big window that let in a lot of sun. Two different stems from each plant were marked with bag ties. The heights of the two stems from each plant were measured. The plants were watered with 157. 6 millimeters of the solution. Each plant was watered on Thursday and Sunday. The first solution contained six millimeters of Colors bleach and 151. millimeters of water. The second solution contained 6 grams of sugar and 157. millimeters of water. The third solution contained 6 grams of salt and 157. 6 millimeters of water. On Friday and Monday the height of the stems of each plant were measured, and the height was recorder. I nerve was also a plant Tanat was watered Just Walt water, Tort ten control setup. This experiment ran for four weeks. The data was analyzed to determine which plant grew the most over that period of four weeks. The conclusions of this experiment are that the plant watered with sugar grew the most. Another conclusion is that the control (the plant watered with water) grew a little less than the plant attired with sugar. The plant watered with salt grew a little less than the control, and the plant watered with bleach grew the least amount. The reason that was discovered for why the plant watered with sugar grew the most was because when plants absorb nutrients, they turn them into some form of sugar. This plant didnt have to do that because it was already absorbing sugar. The other substances, except water, probably Just stopped the plants from growing as much. Plant Growth Experiments The instructions below outline a protocol for conducting plant growth experiments in the laboratory. You may want to make adaptations for use in a greenhouse or outdoors. Purpose: To determine the effect of compost on plant germination and growth. Materials: pots, compost, soil, seeds, light source (sunlight or artificial light) Procedure The first step is to design your own experiment. There are many possibilitiesa few ideas are listed here, but the variations are endless: 0 Test various combinations of soil and compost on plant growth. For example, you might wish to dig a soil sample from your school yard and mix it with various amounts of finished compost for planting experiments. Natural soil is better than prepackaged potting soils for experiments such as this because the potting mixes are formulated for optimal plant growth and already contain significant amounts of compost or humus. ) 0 another possibility is to mix your own potting soil by using vermiculite, sand, and compost. Creating several mixtures using the same percentages but different types of compost is a good way of comparing the influence of the various types of compost on plant growth. For example, you could compare compost at various levels of maturity, compost created using different mixtures of organic wastes, or overoptimistic versus impost created in a thermometric system. 0 if you are interested in investigating the effects of compost tea on plant growth, you could fill the pots with a sandy soil or potting medium such as vermiculite, then use compost extracts for watering. Next, whatever type of experiment you choose, make sure that you design your experiment to include replicates of the various treatments.

Lack of understanding and discriminatory treatment of two-spirit men creates an environment where HIV/AIDS can spread unimpeded. Knowledge of gender and sexual variance in indigenous societies is limited, but what is known is that some tribal communities had more than male and female genders and participated in a variety of sexual orientations (Australian Indigenous 2007).
