Is it possible to be Muslim feminist - Essay Example This is especially due to the rise of women’s rights awareness throughout the world. However, what is neglected when feminist related issues are discussed regarding Islamic oppression of women is the situation of women throughout the world in contemporary times which led to the need for a separate feminist movement. Simultaneously, the situation of women in the past and in the pre-Islamic era also needs to be given sufficient weightage in order to understand the notions of modern day feminism and the teachings of Islam. Firstly, let us take a look at the situation of women in Pre-Islamic Arabia. The women at the time were not considered a part of society. Rather they were considered assets, possessions and ornaments to embellish, use and discard as a source of masculine power. The culture which was largely prevalent at the time was a tribal. But not a kind of tribal culture which is visible in our current day world situation, as for instance, in war-torn Afghanistan. The tribal culture’s motto was to put first, and foremost, the unity and brotherhood of the tribe. The tribe was an entity in its own right. However, it did not have the infrastructure that any highly developed society of modern times would have. Individual rights and properties were not maintained rigidly since the clan consisted of all blood relatives. The property, which included women, remained within the bonds of the tribe and its authority figures who were known as the ‘sheikhs’. Female infanticide was a common practice of the time. Female children were considered disgraceful and unwanted. Male children represented a form of power, wealth, and richness in fertility. As the sole heir of the family they were given full property rights as daughters were being swiped off from the face of the earth. But the main reasons behind killing female infants were relevant to poverty, pride, and the avoidance of

Library Classification Essay Example for Free

Library Classification Essay A library classification is a system of coding and organizing library materials (books, serials, audiovisual materials, computer files, maps, manuscripts, realia) according to their subject and allocating a call number to that information resource. Similar to classification systems used in biology, bibliographic classification systems group entities together that are similar, typically arranged in a hierarchical tree structure. A different kind of classification system, called a faceted classification system, is also widely used which allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in multiple ways. DescriptionLibrary classification forms part of the field of library and information science. It is a form of bibliographic classification (library classifications are used in library catalogs, while bibliographic classification also covers classification used in other kinds of bibliographic databases). It goes hand in hand with library (descriptive) cataloging under the rubric of cataloging and classification, sometimes grouped together as technical services. The library professional who engages in the process of cataloging and classifying library materials is called a cataloguer or catalog librarian. Library classification systems are one of the two tools used to facilitate subject access. The other consists of alphabetical indexing languages such as Thesauri and Subject Headings systems. Library classification of a piece of work consists of two steps. Firstly the aboutness of the material is ascertained. Next, a call number (essentially a books address), based on the classification system in use at the particular library will be assigned to the work using the notation of the system. It is important to note that unlike subject heading or thesauri where multiple terms can be assigned to the same work, in library classification systems, each work can only be placed in one class. This is due to shelving purposes: A book can have only one physical place. However in classified catalogs one may have main entries as well as added entries. Most classification systems like the Dewey Decimal Classification (DDC) and Library of Congress classification also add a cutter number to each work which adds a code for the author of the work. Classification systems in libraries generally play two roles. Firstly they facilitate subject access by allowing the user to find out what works or documents the library has on a certain subject. [1] Secondly, they provide a known location for the information source to be located (e. g. where it is shelved). Until the 19th century, most libraries had closed stacks, so the library classification only served to organize the subject catalog. In the 20th century, libraries opened their stacks to the public and started to shelve the library material itself according to some library classification to simplify subject browsing. Some classification systems are more suitable for aiding subject access, rather than for shelf location. For example, UDC which uses a complicated notation including plus, colons are more difficult to use for the purpose of shelf arrangement but are more expressive compared to DDC in terms of showing relationships between subjects. Similarly faceted classification schemes are more difficult to use for shelf arrangement, unless the user has knowledge of the citation order. Depending on the size of the library collection, some libraries might use classification systems solely for one purpose or the other. In extreme cases a public library with a small collection might just use a classification system for location of resources but might not use a complicated subject classification system. Instead all resources might just be put into a couple of wide classes (Travel, Crime, Magazines etc. ). This is known as a mark and park classification method, more formally called reader interest classification. . see more from: http://en. wikipedia. org/wiki/Library_system.

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.

Moll Flanders by Daniel Defoe :: Moll Flanders Daniel Defoe Essays

Moll Flanders by Daniel Defoe Three recurring themes in Moll Flanders by Daniel Defoe are greed, vanity, and repentance. Theme is defined as an underlying or essential subject of artistic representation. These three themes play an important role in the development of the story of Moll Flanders.   Ã‚  Ã‚  Ã‚  Ã‚  The first theme, greed, is shown in Moll's acts of prostitution. Moll turns to thievery in many instances to support herself. She also allows her morals to disintegrate; a result of her greediness.   Ã‚  Ã‚  Ã‚  Ã‚  Moll's first act of prostitution is thrust upon her unknowingly. In the beginning of the story, she is living with a gentle woman and her family. One of the brothers takes interest in Moll and seduces her into becoming his lover. "He took these freedoms with me†¦ when this was over he stayed but a little while, but he put almost a handful of gold in my hand†¦" (Defoe 26). Moll lets down her guard and meets with the brother frequently. "†¦ so putting the purse into my bosom, I made no more resistance to him, but let him do just what he pleased and as often as he pleased†¦" (Defoe 30). Later in the story, Moll becomes acquainted with a woman who persuades Moll to work for her as a prostitute. Even though Moll is now married, she agrees to sell her body for profit. "I found presently that whether I was a whore or a wife, I was to pass for a whore here†¦" (Defoe 144). Moll's acts of prostitution show that she will carry out illegal practices in order to get money.   Ã‚  Ã‚  Ã‚  Ã‚  Moll's many instances involving thievery also express the theme of greed. At the end of the story, Moll gives her son a stolen watch. "†¦ I stole it from a gentlewoman's side at a meeting house in London" (Defoe 297). Moll says this is the only thing of value she has to give him. One Christmas Day Moll discovers an unattended silversmith's shop. "I went boldly in and was just going to lay my hand upon a piece of plate, and might have done it and carried it clear off†¦" (Defoe 238). Moll resists the temptation to steal because a nearby shopkeeper rushes over after having seen her enter the empty store. While Moll is living with the old governess she has some luck swindling a man at a gaming-house who seems "†¦to be of more than ordinary fashion†¦" (Defoe 230). Moll wins him some money and secretly keeps a part for herself each time. "†¦he divided it with me, and I brought away 30 (sic) guineas besides about forty-

Breaking Through Essay

Throughout the book â€Å"Breaking Through,† Francisco Jinemez discusses many themes. This book is an interesting and a must read book for people who moving to another country and trying to get a better life. There are three themes in the novel that one must follow in order to understand and earn a meaningful life: family, work, and education. First of all, family is the first school in which a child receives the basic values of life. When Francisco was young, his family moved to America, hoping to get a better life. He grew up in a poor family. The six members in his family are his parents, (how many? 3? ) brothers, and sister. His family suffers and struggles with many hardships because they were not coherent English speakers. His mother is a caring and thoughtful woman who places her family as an important priority. She gives Francisco a lot of advice that helped him solve many of his problems. All the members of his family are friendly except his father. His father always yells at him and Roberto when they ask to go out. Although his mood changes invariably like the weather, they still respect him completely. Francisco spends a lot of time with his big brother since their ages are close to each other. Francisco’s love for his family is never-ending. In one part of the book, Francisco and his brother, Roberto, moved away from their family to a different city to live by themselves. At the beginning, Francisco misses his family so much that he can’t help but reminisce about the time when they still lived together. Francisco often misses â€Å"the sounds of [his] Papa’s coughing, the rattle of his aspirin bottle, and the rolling of Mama’s twelve-inch lead pipe† (19). Being away from his family occasionally makes Francisco think of all the little things about his life when he lived with his parents. Jimeneez illustrated an image of Francisco’s life before he moved to _____ in order to demonstrate how Francisco’s strong ties to his family causes him to think about when they were still living together. Everyone has to work whether to earn money or get experience for a better future. When Francisco was still in middle school, he supported his family by working. His work was to pick cotton, carrot, or strawberry, depending on the season. Francisco’s father has trouble with his back, so he could not work as well as he did before. Things get worse when Roberto got married because he is unable to support the family anymore because he needs the money to build his own family. Francisco and his father become depressed as they worry for their life and survival. They often wonder how they will survive with the limited amount of money they receive from their work. Life is tough for them. Why do we have to go to school? It is the best option for our future. In general, achieving an education is not an easy thing to do. It is even harder for Francisco who moved to another country. Although he has problem with English, he never stop trying to learn it. In addition to getting a good education, Francisco also has to help support his family. This caused him to miss many school days. In his senior year, he hears good news from his teacher that he might be able to get a scholarship. He discusses the news with his family, but his father did not approve. Francisco could not control himself and finally talk back to his father that why cannot he get into college. Francisco felt ‘’anger [swallowing him] and [he] could not escape it† (168) Francisco felt passionate about his education because it is the only hope for Francisco to escape his poor life. He believes that he must fight for it because education is not only a ladder to success, but it will also give him knowledge to become a useful person in the future. In conclusion, Jimenez is trying to demonstrate survival and hardship through these themes. These are themes that would help us break through all the hardships in life. A better future depends on our hope and courage.

Globalisation in Australia essays

Globalisation in Australia essays However, many will agree with me that globalisation has come to affect nearly every aspect of daily life, and has a profound effect on the development of the policies which shape our future lives. Globalisation perhaps the buzz-word of the nineties has come to mean many things to people, and our perspective of what it means is largely influenced by how we are affected. Some view globalisation as removed from human values - a bloodless enterprise, made up of computer blips, stock market figures and sales graphs. One person I asked joked globalisation meant 1950s lighting. My local Loys soft drink deliverer tells of his fears that Schweppes will be swallowed up by Coca Cola and no more discounts will be available to home deliverers like himself. He sees that globalisation once a buzzword used only by politicians and economists could intimately affect his life and his ability to bring up his children. People see globalisation like a giant pacman: eating up their familiar brands they took pride in. They went through the angst of losing the corner store thirty years or so ago, now they see they are losing everything that was home grown and familiar in which they had a stake. They feel disenfranchised, angry and diminished. They intend to make someone pay a price for that. Theyll take their anger to the ballot box and heaven help the political Party which pleads globalisation as an excuse. People are wary of change, especially when they are told they have no say in it. The most profound change in the workings of international financial, trade, political and security relations is being passed off as inevitable. National governments have facilitated the growth of globalisation through their dedication to the creation of a global level playing field - a concept in which people have as much faith as, say, Collingwood winning this years Grand Final (with all due respect to Mr ...
