Sonnets 18 and 130 Defending and Defying the Petrarchan...

Sonnets 18 and 130: Defending and Defying the Petrarchan Convention During the Renaissance, it was common for poets to employ Petrarchan conceit to praise their lovers. Applying this type of metaphor, an author makes elaborate comparisons of his beloved to one or more very dissimilar things. Such hyperbole was often used to idolize a mistress while lamenting her cruelty. Shakespeare, in Sonnet 18, conforms somewhat to this custom of love poetry, but later breaks out of the mold entirely, writing his clearly anti-Petrarchan work, Sonnet 130. In Sonnet 18, Shakespeare employs a Petrarchan conceit to immortalize his beloved. He initiates the extended metaphor in the first line of the sonnet by posing the rhetorical†¦show more content†¦Although Shakespeare appears to be conforming, he still elevates his work above the exhausted conventions of other Elizabethan sonneteers. Instead of objectifying his lover through trite comparisons, he declares that she is too beautiful and pleasant to be compared even to a day of the most enjoyable season of the year. While most consider the realm of nature to be eternal and that of humans to be transitory, Shakespeare accentuates the death of a season and imbues his sweetheart with everlasting life. He ingeniously inverts the scheme of things in order to grant his love perpetual existence through his poetry. Unlike Sonnet 18, Shakespeare utterly abandons the poetic convention of Petrarchan conceit in Sonnet 130. In this poem, Shakespeare denies his mistress all of the praises Renaissance poets customarily attributed to their lovers. The first quatrain is filled exclusively with the Shakespeares seeming insults of his mistress. While Sir Thomas Wyatt authors a poem entitled Avising the Bright Beams of These Fair Eyes, in the first line of Sonnet 130, Shakespeare affirms that his mistresss eyes are nothing like the sun. John Wootton, in a poem published in Englands Helicon, boasts that his love has lips like scarlet of the finest dye, but in Sonnet 130 , Shakespeare is sure that his beloveds lips are not nearly quite as red as coral (11; 2). Michael Drayton, in his poem, To His Coy Love, begs his lover, Show me no more those snowy

Much Madness Is Divinest Sense - 963 Words

Amelia Hughes ENG 102 November 21, 2012 Much Madness is divinest Sense Emily Dickinson is was a talented and unique poet; some might even call her strange or mad. This poem, in a way, represents her life that was far from what was considered normal. In the 1800s, a certain type of behavior was expected from people, especially from women. Women cooked, cleaned, and nurtured their families, while under the control of men. It was not looked upon well when women strayed from this status quo. Emily Dickinson did, and this poem demonstrates this rebellion. This poem is short in length, like most of Emily Dickinson s other poems. It contains the use of perfect rhymes, imperfect rhymes, and end rhymes. An example of the perfect rhyme is†¦show more content†¦Ã¢â‚¬Å"Perhaps Dickinson was negatively referring to being â€Å"handled† or controlled by marriage, or worse, in an insane asylum† (Victoriana Online). This seems to be the central focus or message of this poem; escaping the chains of men, society, or anything else that restricts a person from being themselves. Emily Dickinson was a very important poet of the nineteenth century, even though she did not have any of her poems published under her name until after her death. She did have some published anonymously and she put poems in letters to her friends after her isolation. Dickinson s writing obviously did not stop at this though. â€Å"Upon her death, Dickinson s family discovered 40 handbound volumes of nearly 1800 of her poems, or fascicles as they are sometimes called† (Poets Online). She wrote all of these poems for herself with seemingly no intent to get rich or famous off of them, but just to use her intelligence or express her emotions that could not be expressed during this time period. â€Å"Much Madness is divinest Sense† is a very good representation of Emily Dickinson and her life; it was full of intelligence, creativity, and rebellion. Emily Dickinson did not assent with the majority, she demurred and created her own status quo. Works Cited â€Å"Emily Dickinson.† Poets.org: From the Academy of American Poets. Copyright 1997-2012.

Celebrity Status Free Essays

Celebrity Status â€Å"Everything I do need a news crew’s presence† – kanye west. Think back to the early years and recall the one role model that was looked up to the most go ahead might have to go back as far as childhood. Ok got that amazing individual in mind? Now is that somebody a person who had a lifestyle in luxury, fascinates the media and the influences the public on day-to-day basis? (Commonly denoted as an individual with fame and fortune), implied with great popular appeal, prominence in a particular field, and is easily recognized by the public or also known as a celebrity or celeb. We will write a custom essay sample on Celebrity Status or any similar topic only for you Order Now Known fact most role models are celebrities but why? Celebrities are on TV, front page of magazines, and have their names big and bold in newspapers. Every time they turn their head or scratch their nose it’s going to make the headlines and believe it or not things that small from people with big reputation have a huge impact on the public people. Celebs are bad role models because they effect children, families, and can give the wrong meaning of celebrity status. Children the offspring, the next generation need to grow up healthy and with a excellent mental state and not a fantasy trying to copy the latest and greatest movie actor out. he child needs to be an individual meaning one person as him/herself, â€Å"selfhood†. Who knows the child could be a genius and invent something great that could be helpful for the future, but never know because they are to influenced by their celebrity role model. Having celebrities as role models can also throw a good chance of bad be havior in children for example lindsay lohan she effected thousands of young girls with then good girl gone bad incident made national back in 2004 after she made the movie mean girls then later got caught stealing and no penalties were issued. As a role model she portrayed that stealing was ok and being bad is cool plus you just can’t act bad, you have to be bad! It was just that easy to set the mind of a child off track and to follow the footsteps of a â€Å"role model†. As children get older the role model gets older and will still try to do everything they see their role model do because they think it cool or want to be just like them no matter what the action is going from sex all the way to drugs. Drugs are likely to be used before age twenty six by young adults, but when celebrities use drugs it raises the chances even more with teenagers when celebrities are caught red handed by he media. It gives the wrong impression because the whole incident turns into a phenomenon â€Å"what drug did she/he use† â€Å"how long has she/he been using it† it becomes more a reward then punishment because there are now the biggest topic of the month and really miss the point that person made a mistake in l ife and is now addicted when they needed to be taking out of the spotlight so child viewers don’t think twice of making that mistake; but its not that easy. It also gives the impression that everything will be perfectly using drugs and life goes on perfect example Charlie sheen. when Charlie got fired from two and a half men then left for rehab he came back the same man that left but came back with a hit catch phrase duh winning and was offered he’s job back plus endorsements. Celebrities that use drugs are a easy way to influence children to experiment and use drugs so why let them take it that far? The celebrity doesn’t care about their effect on children but their own. Family is the group of people who are willing to do anything for each other and won’t let anything between, so why let a celebrity ruin that? Celebrity role models effect families nationwide by giving the wrong message all the time; like its ok to live young wild and free or better like the new saying of 2012 Yolo so popular it made it to the dictionary. (yo-lo) you only live once. If a role model says it’s ok â€Å"Yolo† it’s just the same as saying its ok to do anything crazy, it’s ok go head live fast because you once live once (Yolo). That saying is being promoted by celebrities and it’s pretty scary. kids have a reason to do something crazy and then are sent to the grave and left mom and dad to mourn the day with the feeling that life will never be the same. A role model should be a positive person and have nothing but good intentions Like a super hero and doesn’t want to harm anyone or do drugs also would lead by example those are true role models. No matter if they’re popular or not that role model will always be above celebrity status! How to cite Celebrity Status, Essay examples

The Road free essay sample

Story Living in a post-apocalyptic world would leave one feeling terrified, alone, and on the brink of going mad, but it is hard to imagine these feelings to the actual extent. In the book The Road, McCarthy is able to draw the readers in for them to experience the real emotions of living in a post-apocalyptic world. The readers are able to feel this fear and realness because McCarthy impersonalizes the two main characters and clearly depicts the differences of life before and after the traumatic experience. When speaking about the two main characters in the book, McCarthy uses no names. The small boy is referred to as â€Å"the boy† and the father of the small boy is referred to as â€Å"the man. † The author described these characters in such a vague way in order to make the readers stray away from thinking that this experience is unique only for the man and the boy. We will write a custom essay sample on The Road or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The reader can now understand that this could happen to anybody. Now the reader can put himself/herself into this role and experience every emotion and experiences to the fullest extent. Also, by giving little description of the characters, the reader can now focus on the relationship of the man and boy as a whole rather than on each separate character. The relationship intensifies the feeling for the readers and allows them to be a part of the bond between the boy and the man. The unknown details about the main characters, ironically, draw the reader in and allow him/her to experience the setting and relationships more thoroughly. Often in the story, there are anecdotes or objects found that make the characters think about the pre-apocalyptic world. The man and the boy visit the house they once lived in. The familiarity of the house sparks memories of their old life. The reader can now compare their house to the man’s house and realize how scary it would be to see their house in such a negative way. Also, the man and the boy find a coke in the beginning of the story. The man explains how that soda is probably the last soda they will ever see. The rarity of a soda puts things in perspective. In normal society, having a soda is a normal occurrence. The readers can now imagine that other regular occurrences in their life that they enjoy would also become an infrequent happening. The comparison that McCarthy makes between the pre-apocalyptic world and the post-apocalyptic world gives the reader the ability to vividly imagine this drastic change of lifestyle. McCarthy is able to paint out, not only, a story, but a dramatic experience. The reader is able to actually live through and feel the emotions of this strange world. They understand how alone and terrified the boy and the man felt throughout their journey. The emotional connection with the story that the readers have is reached with the unique way the author writes and tells this story.

He stills the bottle from hermit’s house. The author also introduces Liu Yun whom he says that though he looked innocent, he was behind all forms of mischief in the village (Ying 49). This shows how young people get introduced to criminal behavior like stealing of books. Although Yun is only three years than the boy, he extremely likes girls in the village. His mischievous behavior had ruined his dream and failed to finish school. As a result, he spends most of his time drinking, smoking, singing dirty songs and hanging in the streets (Ying 49). As the story progresses, we learn about the disappearance of cigarettes from the factory and the police are out man-hunting those behind the crime.

He is intercepted time and again on the road to examine and diagnose sick people in the village. He however hates hospitals and has a negative attitude towards them. Additionally, Big Brother’s description of the family’s financial status demonstrates how poverty has found its way in the family and rooted in the society. Big Brother spends most of his time taking care of other people’s children and laundry. He confesses that it was not his wish but it was away of making ends meet. He notes that they were only left with their father’s wages and pension which was not enough to meet their daily needs (Ying 49). As a single man who wishes to marry in future, Big Brother understands that money was paramount for him to think of marriage. Poverty is further manifested through the kind of meals served. The boy’s mother serves him with soya beans without oil which she considers to be expensive. This illustrates the low quality of meals which the family survives on. Additionally, family members have to carry mats and bamboo beds outside after every dinner in order to allow houses to cool to reasonable temperatures to allow sleep (Ying 54). The description of this scenario depicts a case of poverty facing the society. The author notes that the boy’s mother had a close eye on him, monitoring his single move. She always went along supervising his homework, his time to be in and out of bed, meals and visiting the toilet. The boy further remembers their dad who used to take them fishing and make them laugh especially when he was in his highest spirit (Ying 53). The boy’s mother gets touched so much when the boy comes back with a bleeding noise caused by Liu. She nurses him gentl y although the boy is not willing to mention his attacker.

The Economic Struggles of Landlocked Countries

The Economic Struggles of Landlocked Countries If a country is landlocked, it is likely to be poor. In fact, most countries that lack coastal access are among the world’s Least Developed Countries (LDCs), and their inhabitants occupy the â€Å"bottom billion† tier of the worlds population in terms of poverty.* Outside Europe, there is not a single successful, highly developed, landlocked country when measured with the  Human Development Index  (HDI), and most of the countries with the lowest HDI scores are landlocked. Export Costs Are High The  United Nations  has an Office of the High Representative for the Least Developed Countries, Landlocked Developing Countries, and Small Island Developing States. The UN-OHRLLS holds the view that high transport costs due to distance and terrain detract from landlocked countries’ competitive edge for exports.   Landlocked countries that do attempt to participate in the global economy must contend with the administrative burden of transporting goods through neighboring countries or must pursue costly alternatives to shipping, such as air-freight. The Wealthiest Landlocked Countries However, despite the challenges that most landlocked countries face, a few of the world’s wealthiest countries, when measured by GDP per capita (PPP), happen to be landlocked, including: Luxembourg ($92,400)Liechtenstein ($89,400)Switzerland ($55,200)San Marino ($55,000)Austria ($45,000)Andorra ($37,000) Strong and Stable Neighbors There are several factors that have contributed to the success of these landlocked countries. First, they are simply more geographically fortunate than most other landlocked countries by virtue of being located in Europe, where no country is very far from a coast. Furthermore, the coastal neighbors of these wealthy countries enjoy strong economies, political stability, internal peace, reliable infrastructure and friendly relations across their borders. Luxembourg, for example, is well-connected to the rest of Europe by roads, railways, and airlines and can count on being able to export goods and labor through Belgium, the Netherlands, and France almost effortlessly. In contrast, Ethiopia’s nearest coasts are across borders with Somalia and Eritrea, which are usually beset with political turmoil, internal conflict, and poor infrastructure. The political boundaries that separate countries from coasts are not as meaningful in Europe as they are in the developing world. Small Countries Europe’s landlocked powerhouses also benefit from being smaller countries with longer legacies of independence. Nearly all of the landlocked countries of Africa, Asia, and South America were at one time colonized by European powers that were attracted to their vast size and plentiful natural resources. Even when they gained independence, most landlocked economies remained dependent on natural resource exports. Tiny countries like Luxembourg, Liechtenstein, and Andorra do not have the option of relying on natural resource exports, so they have invested heavily in their financial, technology, and service sectors. To remain competitive in these sectors, wealthy landlocked countries invest heavily in the education of their populations and enact policies that encourage business. International companies like eBay and Skype maintain European headquarters in Luxembourg because of its low taxes and friendly business climate. Poor landlocked countries, on the other hand, have been known to invest very little into education, sometimes in order to protect authoritarian governments, and they are plagued by corruption that keeps their populations poor and bereft of public services – all of which precludes international investment. Helping Landlocked Countries While it may appear that geography has condemned many landlocked countries to poverty, efforts have been made to soften the limitations posed by a lack of sea-access through policy and international cooperation. In 2003, the International Ministerial Conference of Landlocked and Transit Developing Countries and Donor Countries on Transit Transport Cooperation was held in  Almaty, Kazakhstan. Participants designed a Program of Action, recommending that landlocked countries and their neighbors, Reduce customs processes and fees to minimize costs and transport delaysImprove infrastructure with respect to existing preferences of local transport modes, with a focus of roads in Africa and rail in South AsiaImplement preferences for landlocked countries’ commodities to boost their competitiveness in the international marketEstablish relationships between donor countries with landlocked and transit countries for technical, financial, and policy improvements Were these plans to succeed, politically-stable, landlocked countries could feasibly overcome their geographical barriers, as Europe’s landlocked countries have done. * Paudel. 2005, p. 2.

The Montgomery County Public Schools (MCPSa), in Rockville, Maryland have developed their strategic plan for the schools in their district along these lines. MCPS (2008b) have developed their financial resources plan to provide effective business services which provide efficient running of the schools. These are seen as vital for the educational accomplishments of the students. They have involved a larger parental and community support in their planning and budgeting, and in their outreach and partnerships. The business services either meet or go above the requirements of the schools, and they have implemented an arrangement to employ, support and keep hold of highly qualified teachers and other staff members. The financial resources invested each year has increased from 2002 when the budgeted costs for ‘all strategic functions’ at $1.10 per square foot, in 2007 it was $1.22 per square foot (MCPS, 2008b). The human resources that the plan endeavors to produce are equally successful. MCPS (2008) main criteria in these area of resource is to develop and reinforce dynamic partnerships for the education of the students. They also support the relationship from the outside community and their participation in the school to encourage success. Continuous professional training has been implemented; the staff are now offered more support and mentoring has been put into practice for all staff. The plan has enabled the schools to train 138 more staff in leadership training in 2007, than it did in 2002 (MCPSa, 2008). Furthermore, MCPS

Policies & Regulations of Social Media Essay Example | Topics and Well Written Essays - 14500 words

Policies & Regulations of Social Media - Essay Example In social network, users (such as friends or acquaintances) with common interests often share hobbies, information and interests, depending on the privacy settings. Nowadays, Social Networking Sites (SNS) have become prevalent ways of communication. For instance, Government agencies are using SNS such as Facebook, Twitter, MySpace, and Orkut, to execute their e-government functions (McNamara, 2011). Currently, E-governance is widely accepted around the world, especially because it provides different opportunities such as encouraging delivery of service at the government level, reducing the cost of government operations and improving the effectiveness of government functions. Therefore, many governments have adopted e-governance and its related technologies to their perceived benefits. In this view of this, this study will analyse and highlight Saudi Arabia’s social media regulations and policies. 1.1 Aim The aim of this research is to evaluate social media policies and regulat ions in government organizations in Saudi Arabia, which is essential in ensuring effective adoption and usage of social media. 1.2 Objectives These are the main objectives for undertaking this study. To identify the existing social media policies (if any) among government organizations in Saudi Arabia. To document policies and regulations that facilitates and enhances the successful adoption and usage of social media in government organizations. To encourage the government organization in Saudi Arabia to use social media tools because none exists at the moment. To come up with recommendations regarding relevant policies and to control the use of social media 1.3 Research Questions Particularly, through this research, the aim is to answer four major questions regarding the use of social media in Saudi Arabia’s government organizations. These include the following: How are Saudi government organizations using social media? What are some of the difficulties reported in the use o f social media by both the staff and organizational heads? Are there policies and regulations that govern the use of social media in these organizations? If not, why not? What are some of the regulations and policies that can be adopted to enhance effective use of social media in Saudi’s government organizations? 1.4 Research Background In the 1990s, the Internet transformed people’s lives and now social media come with new horizon of sharing information and collaboration. However, to enhance the effectiveness of social media usage for government organizations, social media policy is fundamental. According to Hrdinova et al., (2010), with the increasing demand of the social media, many organizations are trying to cope with the current social media atmosphere and its recent transformation by changing the design of the old policy and regulations of Internet use. However, in these organizations, the manner in which social media has been used, has led to the development of social media policies. Therefore, the study will demonstrate the procedure of implementation, technological application and efficient policy of social media. However, to execute all these, Jana Hrdinova and Natalie Helbig (2011) suggested three core points by which social media can be efficiently used by the government agencies. First, to support the

Properties of Phagraphene via Hydrogenation and Fluorination

Properties of Phagraphene via Hydrogenation and Fluorination Modulation of electronic and mechanical properties of phagraphene via hydrogenation and fluorination Donghai Wu ab, Shuaiwei Wang ab, Jinyun Yuanab* Baocheng Yang ab, Houyang Chenc* a Institute of Nanostructured Functional Materials, Huanghe Science and Technology College, Zhengzhou, Henan 450006, China b Henan provincial key laboratory of nanocomposite and application, Zhengzhou, Henan 450006, China c Department of Chemical and Biological Engineering, State University of New York at Buffalo, Buffalo, New York 14260-4200, USA ________________ Abstract: Recently, a new carbon sheet, phagraphene, was proposed by theoretical calculations [Nano Lett. 2015, 15, 6182]. In this paper, the hydrogenated and fluorinated phagraphene (denoted as H-PHA and F-PHA) sheets have been systematically studied using first-principles calculations. The results of formation energy, ab initio molecular dynamics, phonon dispersion and elastic constants confirm that the modified phagraphene sheets are thermodynamically and dynamically as well as mechanically stable. We find that hydrogenation or fluorination is an effective way to modulate the bandgap, and we also find that adsorption-induced semimetal-semiconductor transition and adsorption-induced semimetal-insulator transition occur. Configuration-dependent bandgap for partially H-PHA and configuration-independent bandgap for fully H-PHA are determined. Adsorption-ratio-dependent bandgaps of H-PHA and F-PHA are also identified. Calculated bandgaps from HSE06 and PBE functionals of fully H-PHA ar e larger than those of F-PHA, and they are comparable to thehydrogenated/fluorinated penta-graphene while they are larger than their corresponding graphene. Dependence of bandgaps of fully H-PHA and F-PHA on the tensile strain is investigated, and our calculations show that an insulator-semiconductor transition occurs upon increasing the tensile strain. Our results also determined that the mechanical properties are controllable by using hydrogenation and fluorination. The calculations of Youngs modulus and Poissons ratio reveal the functionalized phagraphene sheets possess suitable stiffness and resistance to volume deformation, and both are smaller than the pristine phagraphene. 1. Introduction Two-dimensional (2D) carbon-based materials have been attracting great attention due to their fascinating mechanical, thermal, electronic, optical and magnetic properties.1-11 In particular, graphene is the most representative example. Since synthetized by Novoselov et al.6 in 2004, graphene has been extensively studied for its robust stability,12 high crystal quality,13 captivating mechanical and electronic as well as thermal properties.14-18 The covalently bonded honeycomb lattice with perfect hexagonal symmetry of graphene plays a crucial role in forming Dirac cones,19 which gives graphene massless fermions, resulting in the anomalous quantum Hall effects,20 ultrahigh carrier mobility21 and other properties.22, 23 Recently, a new carbon sheet, phagraphene,19 composed of rings containing five, six, and seven carbon atoms, was proposed by theoretical calculations. It can be considered as a defective graphene.24 This planar carbon allotrope is slightly more unstable than pristine graphene while energetically more favorable than other carbon allotropes.19 The notable stability benefits from its sp2-hybridization and dense atomic packing structure.25 Zhang et al.19 have proven that the electronic structure of phagraphene has direction-dependent Dirac cones, which are robust against external strain with tunable Fermi velocities. This unique performance makes the phagraphene an advanced material for numerous applications in photoelectric technology. However, like graphene, the phagraphene suffers a major drawback of zero bandgap and rather robust gapless state, limiting its potential applications. In order to overcome this disadvantage, we use hydrogenation and fluorination to modulate its bandgap in this paper. Thanks to the surface unsaturated C-C dangling bond,26 the chemical modification by adsorbing non-carbon atoms on the surface is an effective way to create a bandgap and tune the electronic, magnetic and mechanical properties of graphene.14, 24, 26-32 Hydrogenation is not only the simplest and manageable adsorption but also the generating hydrides are promising hydrogen storage materials in energy field.33, 34 The fluorine atoms with ultrahigh electronegativity are adsorbed on the graphene surface forming fluorinated graphene, which have been investigated experimentally and theoretically.14, 35, 36 After adsorbing such atoms, the forming C-H and C-F bonds could give rise to the carbon atoms transforming their hybridizati on state from sp2 to sp3, 33 correspondingly, the structural and electronic properties would undergo dramatic alterations. In this work, by employing first-principles calculations, the effect of hydrogenation and fluorination on the bandgap opening of phagraphene sheet is examined. After hydrogenation or fluorination, the bandgap of phagraphene could be opened sizably, changing its electro-conductivity from Dirac semimetal to semiconductor or from Dirac semimetal to insulator. The structural stability and mechanical properties of the modified phagraphene sheet are also investigated. 2. Computational details All the first-principles calculations and abinitio molecular dynamics (AIMD) were carried out by density functional theory (DFT) with the projector augmented wave (PAW) method and performed by the Vienna abinitio simulation package (VASP)37 . The 2D periodic boundary condition was adopted and a vacuum space of 20 Ã… along the perpendicular direction of the phagraphene sheet was included in order to avoid the interactions between adjacent layers. The generalized gradient approximation (GGA) of Perdew, Burke, and Ernzerhof (PBE)38 was applied as the exchange-correlation functional in most of the calculations. Meanwhile, to accurately calculate the band structures, the hybrid Heyd-Scuseria-Ernzerhof (HSE06)39 was introduced. The Brillouin zone (BZ) was sampled using 2à Ã¢â€š ¬ ÃÆ'- 0.01 Ã…Ã ¢Ã‹â€ Ã¢â‚¬â„¢1 Monkhorst-Pack40 k-point mesh density, and the plane-wave basis set with cutoff energy of 600 eV was adopted. The total energy difference of 10à ¢Ã‹â€ Ã¢â‚¬â„¢5 eV and forc e tolerance of 10à ¢Ã‹â€ Ã¢â‚¬â„¢2 eVà ¢Ã¢â€š ¬Ã‚ ¢Ãƒâ€¦Ãƒ ¢Ã‹â€ Ã¢â‚¬â„¢1 were used for the convergence criteria of geometric optimization and self-consistent field. The phonon properties were calculated by the Phonopy package41 with force constants obtained by the finite displacement method.42 3. Results and discussion 3.1 Structural properties Figure 1 displays the structure of phagraphene19 together with its hydride and fluoride. The hydrogenated or fluorinated phagraphene (denoted as H-PHA or F-PHA) sheet is obtained by adsorbing hydrogen or fluorine atoms on both sides of the plane. For fully H-PHA and F-PHA, the ratio of C : H/F is 1 : 1. After optimization, the structures of both fully H-PHA (Figure 1c) and fully F-PHA (Figure 1d) are greatly distorted compared to pristine phagraphene (Figure 1a), resulting in low symmetry with a space group of P21/m (No. 11). The 5-6-7 carbon rings no longer remain in the same plane and become crumpled. The buckling height hb (i.e. the height between the bottom and top carbon layers) of fully H-PHA (0.856 Ã…, see Table 1) is larger than that of F-PHA (0.704 Ã…), and they are much larger than those of hydrogenated/fluorinated penta-graphene (0.42/0.40 Ã…) and graphene (0.46/0.49 Ã…).12 The calculated C-C bond distances of pristine phagraphene in Table 1 are in agreement wi th previous calculations,19 indicating the computational method is valid. All the C-C bond distances in fully H-PHA and fully F-PHA are enlarged compared to the pristine phagraphene, and are close to that of 1.546 Ã… in diamond43 while larger than that of 1.42 Ã… in graphene.1 These facts indicate the C-C bonds of phagraphene transform from the sp2-hybridization double bond to the sp3 single bond by hydrogenation or fluorination. The C-C bonds of fully F-PHA are longer than those of fully H-PHA, which can be explained by the depopulation of bonding orbitals between carbon atoms.27 The depopulation of these bonding orbitals stems from the electron transfer between carbon and hydrogen/fluorine atoms. The C-C bonds (C4-C4 in Figure 1) connecting the adjacent 5- and 7-carbon rings are enlarged to a greater extent than others, which is because of the repulsive interactions and steric effects between the adjacent two H/F atoms in the same side of phagraphene. The C-H and C-F bond di stances are approximately 1.11 and 1.38 Ã… (Table S1), approaching to the typical hydrocarbon and fluorocarbons compounds.44 Similar structure distortions and C-C bond elongation are found in hydrogenated/fluorinated penta-graphene and graphene.12, 26, 44 3.2 Stability analysis To investigate the stability of H-PHA and F-PHA, the binding energy Eb and formation energyEf are calculated (definitions of Eb and Ef are given at Section S1 of Supporting Information). The values of Eb are -2.540 and -2.977 eV/atom for fully H-PHA and fully F-PHA (see Table 1), respectively, implying strong interactions between C and H/F. A possible explanation of the strong attractive interactions between C atoms (of phagraphene) and H/F atoms is that, by adsorbing H/F atoms, the C-H/C-F bonds are formed, and the C-C bonds of phagraphene elongate greatly, which could partially release the stress imposed by the 5-6-7 carbon rings.12 Another important factor for synthesis is the formation energy, which applies to measure the stability against molecular desorption from the surface.44 The negative Ef (-0.276 eV/atom for fully H-PHA and -1.615 eV/atom for fully F-PHA) means that the surface modification is exothermic process and the H-PHA (or F-PHA) has lower energy than that of pristi ne phagraphene and H2 (or F2) molecules. The Eb and Ef of hydride are larger than those of fluoride, which are in accordance with similar systems of hydrogenated/fluorinated graphene (-2.48 eV > -2.86 eV)27 and penta-graphene (-3.65 eV > -4.22 eV).12 It is noticed that the Eb of fully H-PHA and fully F-PHA are close, whereas the Ef of fully H-PHA and fully F-PHA have huge difference. This is because of large difference in the dissociation energy of H2 and F2 molecules.27 The thermal stability is also important for H-PHA and F-PHA and is evaluated using the AIMD simulations with a 2 ÃÆ'- 2 ÃÆ'- 1 supercell and a time step of 1 fs for 5000 steps at room temperature (300 K) and 1000 K. Temperature (T) and total energy (Et) as functions of simulation time are plotted in Figures 2 and S1. T and Et converge to constants and the fully H-PHA and F-PHA keep their integrated structures during the AIMD simulations at the setting temperature. These facts demonstrate that hydrogenated or fluorinated phagraphene not only possesses robust thermal stability at room temperature, but also is resistant to high temperature such as 1000 K. In order to examine the dynamic stability, the phonon dispersion curves along the high symmetry points in the BZ and the corresponding phonon density of states (PDOS) are calculated  (Figure 3). No imaginary frequencies are found for both fully H-PHA and fully F-PHA, demonstrating that they are dynamically stable. There are three obvious acoustic modes in the bottom of the phonon spectra for the two structures, and the double degenerates arise along the XZ path of the BZ. These features are similar to the pristine phagraphene,19 graphene45 and its derivatives.12 From the PDOS, one can see that the H-PHA has a tremendous phonon gap of approximately 40 THz, while it is small for F-PHA (about 3 THz). The vibration frequency is inversely proportional to the effective atomic mass,12 thus the larger phonon gap of H-PHA than F-PHA may be attributed to the much lighter atomic mass of hydrogen than fluorine atom. Meanwhile, the narrow high frequency zone around 87 THz in Figure 3a is c orresponding to the C-H bond vibration modes of H-PHA, in accordance with the case of hydrocarbon.46 These C-H stretching modes are infrared active and useful in characterizing this compound.44 The low frequency range from 5 to 10 THz in Figure 3b mainly consists of the phonon modes of C-F bonds. The middle frequency range is dominated by the motion of C atoms. The C=C double bonds were broken by hydrogenation/fluorination, resulting in the disappearance of C-C vibration modes in the region of 40-50 THz for pristine phagraphene.19 3.3 Electronic structures In order to explore the electronic properties and bonding features, the band structures and density of states (DOS) of partially and fully hydrogenated/fluorinated phagraphene are calculated using both PBE and HSE06 functionals. As an example for partially H-PHA, 60% hydrogenation of phagraphene is chosen and four stable configurations (see Figure S2) are designed. The band structures of these configurations are shown in Figures 4 and S3. One can see that the band structures disperse greatly to single band, leading to the sharp peak appearing in the DOS at the EF. Meanwhile, a sub-bandgap located below or above the primary bandgap was observed. From calculations with PBE functional (Figure S3), the bandgaps of the four configurations vary from 2.65 eV (Figure S3a) to 1.72 eV (Figure S3b) to 0.93 eV (Figure S3c) to 0 (Figure S3d). The PBE functional usually underestimates the bandgap of materials.12 To obtain a more accurate Egap, the hybrid functional HSE06 is adopted. The calculated bandgaps with HSE functional in Figure 4 are 3.70 eV, 2.46 eV, 1.56 eV and 0.54 eV for the four configurations. Thus, one can conclude that the bandgap of partially hydrogenated phagraphene depends on configuration and adsorptio n-induced semimetal-semiconductor transition occurs. Such a functionalized 2D material with a proper bandgap has promising applications in optoelectronics and microelectronics.29, 47 The band structures and DOS of fully H-PHA and fully F-PHA are shown in Figures 5 and S4. From calculations with PBE functional (Figure S4), fully H-PHA and F-PHA have direct bandgaps of 4.29 eV and 3.23 eV, respectively. To examine the influence of configuration on the electronic properties, another four configurations of fully hydrogenated phagraphene (see Figure S5) are taken into account. The calculated band structures of the five configurations (Figures S4a and S6) are almost the same and the bandgaps are approximately 4.29 eV, indicating that the Egap of fully hydrogenated phagraphene is independent of the configuration. Similar behavior was found for fully hydrogenated graphene.27 We also calculated the band structures and DOS with HSE06 functional (Figure 5), and obtained that Egap for fully H-PHA and fully F-PHA are 5.37 and 4.98 eV, respectively. These values are comparable to the Egap of hydrogenated/fluorinated penta-graphene (5.35 eV and 4.78 eV) while they are larger th an those of corresponding graphene (4.97 eV and 4.74 eV).12 Obviously, the Egap of F-PHA is smaller than that of H-PHA. Similar results are found in cases of hydrogenated/fluorinated graphene26, 27 and penta-graphene.12Compared to the pristine phagraphene with zero bandgap, the surface modification via hydrogenation or fluorination can effectively tune its electronic structure from semimetal to insulator. Analysis of the partial DOS (Figure 5) reveals that, for H-PHA, the electronic states near the Fermi level (EF) are primarily originated from the C atoms, while they are dominated by both C and F atoms for F-PHA. Additional, from Figures 4 and 5, one can conclude that the bandgaps of H-PHA and F-PHA depend on the adsorption ratio of H and F atoms. We also examine the effect of strain on the band structures. The obtained stress-strain curves of fully H-PHA and F-PHA under biaxial loading (Figure S7) show that their fracture strains are 0.17 and 0.13, respectively. By changing the biaxial tensile strain, the bandgaps of fully H-PHA and F-PHA remain the direct gaps (Figures S8 and S9). Furthermore, upon increasing the biaxial tensile strain, the bandgap of fully H-PHA increases first and then decreases (Figure 6a), whereas the bandgap of fully F-PHA decreases monotonically (Figure 6b). These behaviors indicate that bandgaps depend on the strain. Strain-dependent bandgaps of other 2D materials were also determined previously.48-52 More interestingly, our calculations show that the bandgap of H-PHA reduces from 5.62 eV (ÃŽÂ µ = 0.10) to 4.42 eV (ÃŽÂ µ = 0.17) and the bandgap of F-PHA decreases from 4.98 eV (ÃŽÂ µ = 0) to 3.01 eV (ÃŽÂ µ = 0.13), indicating that an insulator-semiconductor transition occurs with the tensil e strain changes. To visually describe the electronic structure of fully H-PHA and F-PHA, we calculate the charge density. As shown in Figure 7, the charges are redistributed after hydrogenation or fluorination. Compared to the charge densities of C=C bonds in pristine phagraphene (see Figure S10), the charge densities of C-C bonds in H-PHA and F-PHA are reduced. For H-PHA, the shared charges donated by hydrogen are mainly located between the carbon and hydrogen atoms. For F-PHA, a large number of charges are focused on the fluorine atoms. This difference is a consequence of the different electronegativity of hydrogen and fluorine. For a selected element, its attraction of electrons becomes stronger with higher electronegativity.53, 54 The electronegativity increases gradually from hydrogen to carbon to fluorine.53 Thus the charge transfer is from hydrogen to carbon atoms in H-PHA while it is from carbon to fluorine atoms in F-PHA, which is consistent with other hydrocarbons and fluorocarbons.12, 55-5 7 Moreover, the charge density between H and C is lower than that between F and C, implying the weaker C-H interaction than C-F. The Mulliken population analysis58 shows that the transfer charge amounts are approximately 0.22 and 0.33 electrons for H-PHA and F-PHA, respectively, manifesting the weaker bond strength of C-H than that of C-F. 3.4 Mechanical properties Since the ultrathin 2D phagraphene as well as its derivatives is susceptible to external influences, including mechanical deformation,24 it is necessary to develop an in-depth understanding of their mechanical properties for practical application. The elastic constants are calculated (definitions are given at Section S2 of Supporting Information) and the obtained results are tabulated in Table 2, together with the existing reference data24 for comparison. All the elastic constants of fully H-PHA and fully F-PHA satisfy the mechanical stability criteria of C11C22 à ¢Ã‹â€ Ã¢â‚¬â„¢ C122 > 0 and C66 > 0 for 2D sheets,3, 59 indicating that they are mechanically stable. The in-plane Youngs modulus (E) and Poissons ratio (ÃŽÂ ½) can be derived from the elastic constants using the formulas of E = (C112 à ¢Ã‹â€ Ã¢â‚¬â„¢ C122) / C11 and ÃŽÂ ½ = C12 / C11.24 The E of fully H-PHA and F-PHA are 151.3 and 176.3 N/m (see Table 2), respectively, which are consistent with the results from the stress-strain curves (149.2 and 178.5 N/m for fully H-PHA and F-PHA, respectively). The Poissons ratio ÃŽÂ ½ of fully H-PHA and F-PHA are 0.078 and 0.152, respectively. Because the larger E implies the stronger stiffness and the larger Poissons ratio signifies the stronger incompressibility,24 the F-PHA has better stiffness and resistance to volume compression than the H-PHA, which may ascribe to the stronger C-F bonds than C-H bonds. Compared to pristine phagraphene, the E and ÃŽÂ ½ of H-PHA and F-PHA are significantly reduced. Such reduction may be related to their different charge density distribution and bond nature.12, 24 4. Conclusions In summary, we systematically study the structure, stability, electronic and mechanical properties of hydrogenated and fluorinated phagraphene sheets. Our results show that H-PHA and F-PHA are thermodynamically and dynamically as well as mechanically stable. The binding energy and formation energy of fully F-PHA are smaller than those of fully H-PHA, implying the stronger stability of F-PHA than H-PHA. After hydrogenation or fluorination, the bandgap of phagraphene is opened properly, resulting in an adsorption-induced semimetal-semiconductor transition or adsorption-induced semimetal-insulator transition. Strain-induced insulator-semiconductor transition is also identified. Our band structures demonstrate that bandgap of fully H-PHA is insensitive to the configuration whereas the bandgap of partially H-PHA is sensitive to the configuration. Adsorption-ratio-dependent of H-PHA and F-PHA is also determined. The obtained bandgaps from both PBE and HSE06 functionals of fully F-PHA are s maller than fully H-PHA. The charges are transferred from hydrogen to carbon atoms in the fully H-PHA while it is from carbon to fluorine atoms in the fully F-PHA. The positive Poissons ratios of fully H-PHA and F-PHA manifest that they can well resist the volume deformation.Both the Youngs moduli and Poissons ratios of the two phagraphene derivatives are significantly smaller than the pristine phagraphene. This investigation suggests that hydrogenation or fluorination is an effective strategy to modulate the electronic and mechanical properties of phagraphene for its possible applications in nanoelectronics.

Amish Birthing Paper

The religious and cultural beliefs of the Amish, have led to variations in health care practices that are different from main stream American culture. The Amish believe in simple lifestyles and being â€Å"separate from the world,† this is hallmark for the Amish. They don't use modern conveniences that we do, such as electricity, computers, cars, and phones. They travel by horse and buggy, and grow their own gardens and raise their own cattle for food/milk. Their days are filled with hard work and simple pleasures. Babies are a welcomed gift in the Amish culture and are viewed as a blessing rom God. They believe the # of children they have should be left in God's hands, this is why it's forbidden to use birth control, because it would interfere with God's will. Amish families tend to be large; 6-10 kids is common, and occasionally there are families with up to 20 children born to one mother. When a woman gets pregnant; therapeutic abortions, amniocentesis, and other invasive prenatal diagnostic testing (that some of us may use) is not acceptable. They are happy â€Å"to take what God gives them. † The Amish usually have homebirths or give birth at birthing centers with a midwife. The only time they do hospital births, is when there is risk to the mother or the child. At the hospitals, routine interventions of labor and delivery are not used. IVs are available, but optional. Fetal heart rate monitoring is done intermittently by doppler. Amish women usually labor quietly while husbands support them by rubbing their backs, cooling them with hand fans, and holding their hands. Labor tends to be shorter than average and happen peacefully with controlled pushing. Most mothers breastfeed and are anxious to feed the baby after elivery, but some produce no breastmilk at first, because of the huge workload and stress of a large family, and can't feed the baby until the next day. So in the mean time, they give the baby things like jello water or watermelon seed tea, which is supposed to be good for preventing jaundice. Also, they usually don't pick out names before the delivery; they wait and see â€Å"who the baby looks like† before they name him/her. Amish folk wisdom is also an integral part of their prenatal practices, such as walking under a clothes line will result in still birth, or crawling through a window or nder a table will cause the umbilical cord to be wrapped around the baby's neck. Complications such as pregnancy-induced HTN and diabetes (which is higher in Americans) is low in the Amish culture, most likely due to the well-nourished state of the mom, because she eats home-cooked and self-preserved foods (instead of fast food, which is convenient for us. The greatest risk factor for the pregnant women is development of painful varicose veins because of all the heavy work they do. In preparing for the childbirth process, a 5 week formula is sometimes used in the ast 5 weeks of pregnancy to tone and calm the uterus, quiet the nerves, ease pain, and help make labor easier and on time. This formula has also been known to help with menstrual disorders, morning sickness, and hot flashes. It has been passed down from one generation to the next. This formula consists of 5 herbs including: 1.  Red Rasberry leaves: relieves nausea and pain in labor. 2. Butcher's Broom Root: this herb is used for hemorrhoids, varicose veins, and thrombosis. 3. Black Cohosh Root: relieves spastic muscles, dilates peripheral blood vessels, and helps reduce B/P. These actions help the terus and other muscles during labor. 4. Dong Quai Root: it is an anti-inflammatory and diuretic effect and helps to treat swelling prior to labor. During labor it eases smooth muscle contractions and gives a general sedative effect. 5.  Squaw Vine Root: Used to prepare the uterus for childbirth and speed up delivery and encourage regular contractions. It has an antispasmodic action. (This is about the only pain relief/ medications that they use to help with pregnancy/delivery, besides maybe Tylenol. ) A person's life philosophy and religious views profoundly impact the childbirth and parenting experience. Having a positive attitude toward the birthing process, a healthy lifestyle, and adequate support makes childbirth a better experience for the patient. Some nursing interventions that could be used; since varicose veins are the greatest complication for pregnant Amish women (from all of their house work and laundry they do), I would remind her that she should take frequent rest periods from standing and elevate her legs. Maybe if she has older children, they could do some of the house work while mom rests. I would remind her that medication is available for pain relief if she chooses to accept it. I would provide her and her family a warm and comfortable environment, to make them feel at home. I would also encourage the family to bring in home-cooked meals to help her and her husband feel at home. After delivery, if the mother started to feel too tired, and needed some rest I would care for the baby for short periods of time, and help with diaper changes and baths. As I mentioned before, the mother sometimes can't lactate at first and isn't able to feed the baby, so as a nurse I would offer bottles of formula to her so she could feed the baby until shes able to produce er own breastmilk (whether she accepted it or not would be up to her and her husband). The only time an Amish woman gets to rest is right after she has the baby, so the families usually have a â€Å"helper† around for 6 weeks to care for the other children, clean, cook, and do laundry. So before the family leaves the hospital/birthing center, I would make sure they had someone lined up to help them out for at least 6 weeks after birth. I would also make sure she, as well as the family, understands instructions and reasons why interventions are offered.

Moses Maimonides A Scholar Of The Middle Ages Who Decoded

MOSES MAIMONIDES Moses Maimonides, widely known as RaMBaM was a scholar of the Middle Ages who decoded, translated and created major Jewish texts, which much of Judaism has foundations on. Through his works, namely the Commentary of the Mishnah, the Guide for the Perplexed, and the Mishneh Torah, Maimonides aided the Jewish community through the clarifications of beliefs, the challenge of questioning one’s beliefs, maintaining relevances to the Jewish community and shaped interactions within and between Judaism and other cultures and religions. Both the people of his context, and modern Jewish society have been shaped by Maimonides, in scholarship, lifestyle and Jewish renewal, despite criticism from other scholars. Maimonides clarified Jewish principal beliefs, about God, responsibility and various laws. The Mishneh Torah, a reprised version of the Torah logically and systematically indexed (1), and the Commentary on the Mishnah, aided appreciation of Oral Law, without excessive study of the Torah, Talmud, nor Mishnah. His works compiled Judaism’s main beliefs into the ‘13 Articles of Faith’ and the 613 mitzvot. (2) The Articles of Faith defined a focus onto Judaism’s essences on God and His nature, which are standardly incorporated into Jewish literature, creeds, and prayer books. This emphasises its importance to Jewish expression and rituals, domestic and communal celebrations. Similarly, the Mishneh Torah forms the halakhic code, through philosophical essays, Jewish
