Effects of Technological Advances - 806 Words

From the time printed publications were the dominant medium to the modern era where the internet has emerged as the dominant medium the field of journalism has experienced colossal growth, development, and evolvement. The changes caused by the gradual introduction of new and more efficient mediums consistently affected journalism and the way journalists delivered content to the public. Prior to the concept of broadcasting, newspapers were the primary means of communication in society. Initially newspapers were a means of spreading news, usually on a local or regional level. In the times of the Civil War newspapers were used to spread news through out connected areas, in that time being the North and the South. The invention of the†¦show more content†¦With the ability to access content at any time and filter through content that you want at your own pace things were again changed dramatically. Journalists and all outlets of the media were forced to adapt to the changes brought on by the internet. Eventually as internet usage skyrocketed and all outlets of the media have in some way integrate into the internet. The popularity of the internet flipped the journalistic world upside down, and today anyone with their own blog can â€Å"report† to people on a wide scale just the same as newspapers, television, and radio. In the modern day world by linking together with satellite and internet communication, the world has finally been able to come together as one global community. The capabilities the internet has brought now allows journalists to reach people from all over the globe, which is a great change from the times of the Civil War and news being spread and created on a local and regional basis. In conclusion, it is important to consider that with each advancement in communication beginning with printed text and then to radio and television and then internet, communication throughout the world at large has increased dramatically. Throughout these advancements journalism has evolved and has remained an important part of our society. Reference Page James G.

Feminist Criticism The Scarlet Letter - 1324 Words

Andrea Rhoden English IV Almack 1st six weeks The Scarlet Letter:Feminism Feminist criticism is a form of literary criticism that uncovers the common mistreatment of women in literature. For centuries, women have been viewed as the minorities, unable to control and protect themselves. In history, women have had little to no voice in the world, what little bit of a voice they have is only obtained through marriage. Men are so dominant that they are able to get away with crimes far easier than women, when a crime is committed it is far more shocking for it to come from a women rather than a man. The Scarlet Letter depicts the concept of feminism perfectly from the very beginning, Women are a tool used to reproduce and men are the main concern to do everything else including make decisions. As far back as the history books go we have accounts where men were the rulers and women were seen as unimportant or even as a blemish on the face of the society. This sadly is demonstrated using Hester Prynne. Majority of the time the women are looked down upon for things that men do as well, for some reason it is viewed that it is worse for a women to perform these acts than it is a man. Hester is found guilty of adultery because she is found to be with child while her husband is away. Hester has vowed to keep the name of her fellow sinner a secret which we later find out is because he is a higher member of society.

Employment Discrimination And Its Significance - 1190 Words

Employment Discrimination and Its Significance in Canada. A majority of immigrants encounter employment disadvantage or discrimination, compared to native-born Canadians. It’s difficult to obtain suitable employment, so immigrant skills are underutilized, earning less income than native-born Canadians (Oreopoulos, 2011; Reitz et al., 2014). It is asserted that discrimination in employment is an act which negatively affects the employment situation of individuals because of membership in a group, and not because of qualification or capacity to contribute to productivity (Lecture 7: Slide#5). Oreopoulos (2011) observed that, immigrants who entered Canada based on their skills do poorly in the labour market. In another study Reitz et al. (2014) argued that, employment discriminatory behavior creates skill underutilization or ‘brain waste’ for immigrants and lowers their human capital value. So, despite entering Canada with high skills level similar to that of native-born Canadians, immigrants have very little success in ob taining skilled-based employment. Prejudice attitude of recruiters or employers may overlap with the social identity theory that asserts that immigrants are seen as cultural threat because they are not distinctly assimilated into the host country (Harrell et al., 2012).

Describe the adaptations of the human placenta and foetus to improve oxygen availability Essay Example For Students

Describe the adaptations of the human placenta and foetus to improve oxygen availability Essay Describe the versions of the human placenta and fetus to better O handiness. ( Dr P. Bush ) The human placenta is an organ located in the womb. It plays a immense function in the active conveyance of foods and metabolic wastes across the barrier dividing maternal and fetal compartments. Oxygen conveyance from maternal to fetal blood is a primary map of the placenta. It is improbably of import for the growing of a healthy fetus and to guarantee normal fetal development. The fetus is the name given to the developing immature that is besides located in the womb. Communication between the placenta and fetus is particularly important in order to do certain intrauterine growing deceleration is prevented. ( Garnica AD1and Chan WY, 1996 ) Variations in growing of the placenta and its vascular opposition, alterations in the O transportation in the placenta, and changes in alimentary transportation and interactions between female parent, placenta and fetus all have of import effects on the adaptations of the fetus thought to be cardinal to programming. Therefore future adaptations to better placental map are likely to hold womb-to-tomb wellness benefits for the progeny. ( Keith M. Godfrey, 2002: S20-S27 ) One of arguably the most of import adaptations is the O affinity of fetal hemoglobin. Foetal hemoglobin has an O affinity times three to four times higher than that of maternal hemoglobin. In the blood supply of the placenta to the fetus, the O affinity of fetal blood exceeds the affinity of the maternal blood, this hence facilitates the transportation of O in the fetus. In a human gestation, if maternal and fetal bloods equilibrate at a PO2of 30mm Hg, maternal hemoglobin will be at a impregnation of about 50 % , whilst fetal hemoglobin will hold achieved a impregnation point of about 80 % . This explains why fetal blood is ever rather extremely saturated even at the low PO2degrees found in the umbilical vena. ( A.M. Carter, 2009: 19-25 ).This means oxygen dissociates from the female parents hemoglobin and is therefore transported to the fetus. Both the maternal and foetal haemoglobins have four binding sites for O. The larger the measure of adhering sites that are occupied the highe r the per centum impregnation of O. In the placenta the partial force per unit area of O can be used to mensurate the even the smallest sum of dissolved O. The positive correlativity that occurs between the partial force per unit area of O and the measure of haemoglobin that is saturated is known as the O dissociation curve. The form of the O dissociation curve represents the features of O conveyance. The sum of impregnation in the haemoglobin alterations with a alteration in the PO2, and due to its considerably higher affinity for O the curve that is stand foring foetal hemoglobin displacements to the left. ( McNanley T. and Woods J, 2008 ) This enables the fetus to hold better entree to oxygen from the mother’s blood stream ensuing in a more efficient development of the offspring’s respiring tissues. Besides the development of the beta goblin cistron composite has helped to do an addition in oxygen handiness, duplicate of an embryologic cistron yielded HBG-T2, a cistron that is expressed in the fetus and consequences in a higher O affinity on its hemoglobin. It besides consequences in a fatally expressed fluctuation of hemoglobin ( HBB-T3 ) that besides has a high O affinity. This means more O can be bonded to each hemoglobin and transported to the fetus via the blood supply. ( A.M. Carter, 2009: 19-25 ) Gamma ironss are adapted to hold a high affinity for O, this greatly aids an addition in oxygen handiness The gamma concatenation improves oxygen handiness, it is a molecule that has four rule ligands, these include O, C dioxide, H ions and besides 2,3-diphosphogglycerate ( DGP ) . How it works is that if one of the ligands bonds to the hemoglobin molecule it causes a lessening in the hemoglobins affinity for any of the other three ligands. This construct is known as the Bohr Effect, this is a rule that consequences in exchange of O in the tissues being so efficient. For illustration if C dioxide bonds to a hemoglobin in the gamma concatenation, it decreases its affinity for O and therefore the O is offloaded. However, at the placenta C dioxide is offloaded by fetal blood to maternal blood, this is known as a dual Bohr Effect. Binding of H ions and DGP besides cut down the gamma ironss affinity for O. .u03a853244f1d90af3cf4a2afd6c5f623 , .u03a853244f1d90af3cf4a2afd6c5f623 .postImageUrl , .u03a853244f1d90af3cf4a2afd6c5f623 .centered-text-area { min-height: 80px; position: relative; } .u03a853244f1d90af3cf4a2afd6c5f623 , .u03a853244f1d90af3cf4a2afd6c5f623:hover , .u03a853244f1d90af3cf4a2afd6c5f623:visited , .u03a853244f1d90af3cf4a2afd6c5f623:active { border:0!important; } .u03a853244f1d90af3cf4a2afd6c5f623 .clearfix:after { content: ""; display: table; clear: both; } .u03a853244f1d90af3cf4a2afd6c5f623 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u03a853244f1d90af3cf4a2afd6c5f623:active , .u03a853244f1d90af3cf4a2afd6c5f623:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u03a853244f1d90af3cf4a2afd6c5f623 .centered-text-area { width: 100%; position: relative ; } .u03a853244f1d90af3cf4a2afd6c5f623 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u03a853244f1d90af3cf4a2afd6c5f623 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u03a853244f1d90af3cf4a2afd6c5f623 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u03a853244f1d90af3cf4a2afd6c5f623:hover .ctaButton { background-color: #34495E!important; } .u03a853244f1d90af3cf4a2afd6c5f623 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u03a853244f1d90af3cf4a2afd6c5f623 .u03a853244f1d90af3cf4a2afd6c5f623-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u03a853244f1d90af3cf4a2afd6c5f623:after { content: ""; display: block; clear: both; } READ: How Overpopulation Causes Social Problems. EssayAdaptations that are made to the structureof the placenta can assist do betterments to oxygen handiness for the fetus in a figure of different ways, get downing with the construction of the placenta itself. The mature placenta is normally disc shaped with a radius of 9.5cm and a thickness of 2.5cm. The surface of the placenta that is attached to the endometrium of the uterine wall is called the basal home base and the surface nearest the fetus is called the chorionic home base. Between these two home bases is a complex vascular web through which O, food and waste exchange is undergone. The vascular web subdivisions out from t he chronic home base, this creates a system of villi, which so terminate into terminal villi which finally terminates into a system that contains a bifurcate system of capillaries. The terminal villi are the smallest subdivisions within this system and the country where the villous membrane is thinnest and hence it is here where O is transferred, due to the little diffusion distance for gaseous exchange it therefore plays an of import function in O transportation and hence increasing its handiness to the fetus ( Ahokas, R. McKinney E, 2008 ) The capacity of diffusion of O is straight relative to the distance of diffusion between the placenta and the fetus. This is a lending factor to why we are continually interested by the figure of cell beds that are contained in the placenta. Placentas are ever either, epitheliochorial, endotheliochorial or haemochorial, depending on a figure of factors including of the trophoblast is opposed to uterine epithelial tissue, the endothelium of the maternal vass, or if it straight exposed to maternal blood. However it can be said that the type of placenta is truly of really small functional significance in bettering O handiness, and factors such as extended cutting of the tissues is a batch more effectual, cut downing the diffusion distance between fetal and maternal blood even in a placenta which is of the epitheliochorial type. ( A.M. Carter, 2009: 19-25 ) The capacity of diffusion in a placenta increases with gestational age due to factors including growing and distinction. As the villi in the placenta develop, it causes an additions in their surface countries and a lessening in their thickness. As the villi mature their blood supply improves, and their vass adapt to go closer to the bed called the syncytiotrophoblast. Besides the cutting of the villus stroma and trophoblast bed is responsible for most of the addition in diffusion, as it reduces the diffusion distance for O. During gestation there is the greatest betterments to the placenta in bettering diffusion to the feotus. ( McNanley T. and Woods J, 2008 ) The size of the placenta has a direct consequence on the capacity for alimentary transportation via alterations in surface country for conveyance. The weight of the placenta is positively correlated with birth weight. A little placenta additions alimentary conveyance capacity via morphological versions such as an increased surface country for alimentary exchange, vascularity and decreased barrier thickness. These versions affect placental conveyance capacity and the foetal to placental weight ratio. The transportation of blood is undergone by a system known as the counter current system, it takes topographic point in the capillaries of the placenta. It is a procedure in which two blood streams are fluxing in straight opposite waies to each other. This consequences in a big diffusion gradient for the transportation of O between the two blood streams, as it is transported by simple diffusion. This provides an highly more efficient transportation of O to the fetus than if the system was that of a con-current system in which two blood streams flow in the same way. Besides seting into consideration how O transportation across the placenta merely occurs by simple diffusion, a big diffusion gradient provides an excess drive force. .u6c771855fe3191d99302c1a0a318873d , .u6c771855fe3191d99302c1a0a318873d .postImageUrl , .u6c771855fe3191d99302c1a0a318873d .centered-text-area { min-height: 80px; position: relative; } .u6c771855fe3191d99302c1a0a318873d , .u6c771855fe3191d99302c1a0a318873d:hover , .u6c771855fe3191d99302c1a0a318873d:visited , .u6c771855fe3191d99302c1a0a318873d:active { border:0!important; } .u6c771855fe3191d99302c1a0a318873d .clearfix:after { content: ""; display: table; clear: both; } .u6c771855fe3191d99302c1a0a318873d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u6c771855fe3191d99302c1a0a318873d:active , .u6c771855fe3191d99302c1a0a318873d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u6c771855fe3191d99302c1a0a318873d .centered-text-area { width: 100%; position: relative ; } .u6c771855fe3191d99302c1a0a318873d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u6c771855fe3191d99302c1a0a318873d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u6c771855fe3191d99302c1a0a318873d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u6c771855fe3191d99302c1a0a318873d:hover .ctaButton { background-color: #34495E!important; } .u6c771855fe3191d99302c1a0a318873d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u6c771855fe3191d99302c1a0a318873d .u6c771855fe3191d99302c1a0a318873d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u6c771855fe3191d99302c1a0a318873d:after { content: ""; display: block; clear: both; } READ: Yes To the Bombing EssayIn decision, there are a figure of different adaptations to the placenta and fetus that have resulted in an addition in oxygen handiness. These adaptations have developed of course over many old ages to better O handiness to human fetuss and efficaciously better their opportunities of endurance, growing and wellness.
