Big 5 Sporting Goods External and Internal Environmental Analysis Big 5 Sporting Goods (Big 5) has operated within the sporting goods industry, predominantly in the western United States, for over 50 years (Hoovers, 2013). To understand the organizational structure and strategic path chosen by Big 5, it is critical to analyze various factors found within its external and internal environments. Big 5’s external environment includes remote, industry, and operating factors whereas the internal environment includes human capital resources and organizational structure factors. Ultimately these external and internal environmental factors provide opportunities and threats that help to develop and alter generic and grand strategies to meet Big†¦show more content†¦Ultimately understanding and analyzing the effect of each remote environmental factor will allow Big 5 to implement targeted strategies to capitalize on opportunities and minimize threats. Industry Environment Industry environment pertains to how an organization copes with the five basic forces that shape the competitive market in which it operates. How these forces relate to each other will determine the competitive nature of the industry and control how much profit can be made. In a perfectly competitive market, where new entrants are fairly consistent and lack barriers, the likelihood of long-term profits is low. This is seen in such industries as plastics and rubber. The five basic forces consist of suppliers, buyers, new entrants, substitutes, and industry competitors (Pearce, Robinson, 2011). Big 5 Sporting Goods industry environment starts with determining the possibility or ease of new entrants into the market. The ease of the market depends on how many barriers exist for entrants. There are six major sources of barriers, the first being economies of scale. Economies of scale allows Big 5 to purchase a large quantity of a product at a reduced per item cost. This in turn allows them to sell that product at a competitive price in the market. This creates a capital barrier for new entrants.

Pursuit of the American Dream in Great Gatsby and Death...

Comparing the Pursuit of the American Dream by Jay Gatsby and Willy Loman (Essay outline also included in the word count.) People from all around the world have dreamed of coming to America and building a successful life for themselves. The American Dream is the idea that, through hard work and perseverance, the sky is the limit in terms of financial success and a reliable future. While everyone has a different interpretation of the American Dream, some people use it as an excuse to justify their own greed and selfish desires. Two respected works of modern American literature, The Great Gatsby and Death of a Salesman, give us insight into how the individual interpretation and pursuit of the American Dream can produce tragic†¦show more content†¦Despite receiving little payoff for his efforts, he regularly gives extravagant parties to impress others, always half expecting [Daisy] to wander [in] some night (84). Similar to Gatsby, Willy Loman from Arthur Millers Death of a Salesman, bases his American Dream on the idea that public acceptance would bring him wealth. Willy believes that appearing well liked makes him successful. Willy has based his life on the idea that if you are well liked, you will never want (Miller 33). Moreover, he believes his sons appearance will make them successful because they are both built like Adonises (33). Furthermore, Willys obsession with money leads him to equate the value of an individual with their financial worth. Willy idealized his older brother Ben because he is rich (41). Willy, reflecting on his own worth, concludes you end up worth more dead than alive (98). Finally, Willy thinks that being a popular and successful businessman will win him the love of his wife and children. Willy lies to his family, by telling his sons [if there is] one thing boys: I have friends(31). He also exaggerates terribly by telling his wife he sold five hundred gro ss in Providence and seven hundred gross in Boston (35). In his final imagined discussion with his brother Ben, Willy concludes that by taking his own life he will finance his sons business venture, and [Biff will] worship me for it (135).

Don Quixote Reality vs. Illusion free essay sample

An analytical paper which compares and contrasts the theme of reality vs. illusion in Don Quixotes world. A paper which shows how reality and illusion are interwoven not only throughout the story line of Don Quixote exploits, but how author, Miguel de Cervantes, even leaves the true authorship of this tale in question, suggesting that he is merely translating the story from the original writings of Cide Hamete. The paper discusses the madness of Don Quixote who sees people and objects in his everyday life as the counterparts in his knights and damsels world of chivalry, and how Don Quixote charging the windmills has become a classic scene and now serves to symbolize bravery in vain. Cervantes begins Part Two of Don Quixote again referring to the writings of Cide Hamete, thus, lending credence to both, Don Quixote and Hamete as real historic characters (Cervantes, 529). This further adds confusion between reality and fantasy. We will write a custom essay sample on Don Quixote: Reality vs. Illusion or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Throughout the novel there are countless scenes crossing the line of reality and illusion.

R ecent interest has been are capable of controlling the release of chemotherapeutic gents directly inside cancer cells[l]. Nanomaterials are expected hopefully to revolutionize the cancer diagnosis and therapy. Nanoscale particles decorated with multiple functionalities are able to target and visualize tumor site via an imaging technology, thereby allowing for the early detection of cancer. Furthermore, intelligent nanosystems can be constructed as controlled delivery vehicles which are capable of delivering anticancer drugs to a predetermined site and then releasing them with a programmed rate, which can improve therapeutic efficacy[2]. In inorganic nanoparticles, metal nanoparticles have eceived considerable attention in recent years because of their unique properties and potential applications in Fathima Stanley Rosarin et al. /Asian Pacific Journal of Tropical Medicine (2012)1-10 catalysis, photonics, optoelectronics, biological tagging and pharmaceutical applications. A number of approaches are available for the synthesis of silver nanoparticles (AgNPs). For example, silver ions are reduced by chemical, electrochemical, radiation, photochemical methods, Langmuir-Blodgett and biological techniques[3-9]. Among these methods, biological synthesis is a good way to fabricate benign nanostructure aterials. Biological technique is less toxic and eco friendly, in the synthesis of nanoparticles capping agents are used. Capping agent is absorbed by nanoparticles. They are usually organic molecules, and used to aid stabilization of nanoparticles. Silver nanoparticles were synthesized by various plant materials as capping agents such as papaya[10] and neem[11]. Polyphenols of Phyllanthus emblica (P. emblica) includes hydrolysable tannins, flavonoids, alkaloids, gallic acid, ellagic acid and quercetin [1 2], and this plant exhibits antioxidant[13], adaptogenic[14], and hepato-protective action[1 5]. Due to the existence of the conjugated ring structures and hydroxyl groups, many phenolic compounds have the potential to function as antioxidants by scavenging superoxide anion[16] and singlet oxygen[17]. Metal nanoparticles can be synthesized in the average size of more than 50 nm, therefore their large surface area has the ability to carry a relatively high drug dose. Functionalizing the surface of conventional metallic nanoparticles like gold and silver to carry drugs is under investigation. investigate the anticancer effect of PE-AgNPs and drug delivery efficacy of Ag nanoparticles on Hep2 (laryngeal pidermoid carcinoma, a common malignant tumor of head and neck)[18] cell line which has not been previously studied. The biological applications of silver nanoparticles (AgNPs), antimicrobial properties in particular have been widely studied[19]. AgNPs are known to be cytotoxic to both normal and cancer cells in mammals [20] and the modes of interactions of AgNPs have been investigated in different prokaryotic and eukaryotic systems [21-23]. Since nanoparticles ( NPs) are more biocompatible than the conventional therapeutics, they are exploited for drug encapsulation and delivery[24]. It has been stressed over he years that size reduction of NPs play an important role in improving their bioavailability as well as compatibility for therapeutical applications in diseases like cancer[25]. Silver nanoparticles (AgNPs) have a great potential in cancer management because it selectively involved in disruption of the mitochondrial respiratory chain by AgNPs leading to production of ROS and interruption of ATP synthesis, which in turn cause DNA damage[26,21]. Based on the conflicting results, here is an urgency to evaluate cytotoxicity and apoptotic properties of PE-AgNPs on hep2 cells. In order to study the properties of PE-AgNPs to induce apoptosis n cancer cells, it was compared with a standard reference drug 5-flourouracil (5-FU) and we also compared P. emblica fruit extract (alone) with its encapsulated AgNPs. For this study, we employed a well characterized AgNPs to access its apoptotic function via its cytotoxicty and oxidative stress. Dose was fixed and applied in the Hep2 cells by the cytotoxicity test. Based on this study and our ability to access the interaction and interference with a wide range of biological functions, PE-AgNPs employed in the present study provide a unique opportunity to investigate oxidative stress, intracellular ROS generation, apoptotic bodies and poptotic DNA fragmentation, and mitochondrial membrane potential and toxicity in human laryngeal carcinoma cells (Hep2 cell line). Though the AgNPs induces mitochondrial mediated apoptosis[27], we have made an attempt to cap the AgNPs with potent biomolecules of P. mblica and we assessed the toxicity and examined the apoptotic function of PE-Ag NPs which comprised of biomolecules of P. emblica and silver precursors. 2. 1 . Silver nanoparticles The silver nanoparticles were synthesized using previously published procedure in which AgNPs were produced through ion reduction and subsequent stabilization using aqueous xtract of P. emblica fruits. In this method P. emblica pericorps were initially rinsed thrice in distil led water and dried on paper toweling. About 25 g of fruit were cut into fine pieces and boiled with 100 mL sterile distilled water for 5 minutes and filtered through Whatman No. l filter paper twice. The filtrate was stored at 4 C and used for the present study. About 10 mL of aqueous fruit extract was added into the 100 mL aqueous solution of 1 mM AgN03 (AR)[28]. The 100 mL of 1 mM silver nitrate solution was reduced using 10 mL of P. emblica extract at room temperature within 10 min. Ag ion reduction was monitored by measuring the UV-vis spectrum of the reaction medium at various time intervals (5 min to 78 h) in room temperature. The pellet of AgNPs obtained after centrifugation was air dried and mixed with KBr and the KBr-AgNPs pellet was subjected to FTIR to ensure the formation of silver nanoparticles with encapsulation of biomolecules of P. emblica. A scanning electron microscope was used to record the micrograph images of synthesized AgNPs, the particle size distribution of AgNPs was evaluated using dynamic light scattering measurements. These well characterized silver nanoparticles ere further used for cytotoxicity and oxidative stress on cancer cells. 2. 2. Cell culture The human laryngeal carcinoma cell line ( Hep2) was purchased from National Centre for Cell Science, Pune, I ndia. T he cells were cultured as monolayer in MEM supplemented with 10% FBS, 1% glutamine and 100 IJ/mL penicillin-streptomycin at 37 C in 5% C02 atmosphere, stocks were maintained in 25 cm2 tissue culture flasks. A stock solution of PE (1 mg/mL) and PE-AgNPs (1 mg/mL) was prepared in 0. 5% dimethyl sulphoxide (DMSO) (w/v) and stored at 4 C further dilution was made in culture media to obtain the desired oncentrations. The final concentrations of DMSO in the culture medium were not more than 0. 01% (wv). 0. 01% DMSO was used as a sham control. C ells were treated with different concentration of PE and PE-AgNPS (1, 5, 10, 20, 30, 40, 50 fig,t-nL) and the cytotoxicity was observed by (3-4, 5-dimethyl thiaz012yl)-2, 5-di phenyl tetrazolium bromide (MTT) assay. MTT assay was first proposed by mossmon[29]. IC50 value was calculated and optimum dose of PE and PE-AgNPs was fixed in this assay for further study. It is a colorimetric assay for measuring the activity of enzymes that reduce MTT to purple color. Formazan product is directly proportional to viable cells. 10 GL of MTT solution (5 mg/mL in PBS) was added to each culture well after 24 hours of incubation with PE and PE-AgNPs treatment. The color was allowed to develop for additional 4 hours incubation. An equal volume of DMSO was added to stop the reaction and to solubilize the blue crystals. The absorbance was taken using UV-visible spectrophotometer (Elico SLl 59, India) at a wavelength of 570 nm. OD value was subjected to sort-out percentage of viability by using the following formula, OD value of experimental samples. Percentage of cell viability= OD value of experimental sample (AgNPs) OD value of experimental control (untreated) 2. 4. Cell treatment The Hep2 cells were treated with PE and PE-AgNPs in the following concentrations as revealed by MTT assay. They are Group l- Control (untreated cancer cells), Group ll- Hep2 cells (30 Gg/mL PE), Group Ill Hep2 cells + 20 fig/mL PE-AgNPs and Group IV Hep2 cells + 30 Gg/mL 5-FU. After treatment they were incubated at 37 C in 5% C02 incubator after 24 h incubation. The cells were harvested by trypsinization for further experiments. . 5. Reactive oxygen species generation R eactive oxygen species was assessed following the rocedure described by J esudason et al [30]. C ells were seeded in 96 well plate and incubated with PE extract (30 figmL), PE-AgNPS (20 fig,t-nL) and 5-FU (30 for 24 h. A fter incubation, fluorescent dye 2 , 7 dichlorfluorescein-diacetate (DCFH- DA) a non-fluorescent probe that can penetrate into the intracellular matrix of cells, wh ich were then kept in incubator for 30 min. Then the cells were washed with PBS to remove the excess dye. . 6. Mitochondrial membrane potential Mitochondrial membrane potential was evaluated following the procedure described by B hosle et al [31] using the Rhodamine-123 (Rh-123) which is a lipophilic cationic dye, 3 highly specific for mitochondria. The cells were seeded in 96 well plate and treated with PE (30 fig/mL), PE-AgNPs (20 fig/mL) and 5-FIJ (30 fig/mL) and incubated for 24 h. A fter incubation of the cells, fluorescent dye R h- 123 (5 mmol/L) was added to the cells and kept in incubator for 30 min. Then the cells were washed with PBS and viewed under fluorescent microscope using blue filter. 2. 7. Apoptotic morphological changes The apoptotic bodies which were the result of treatment with PE-Ag NPs was assessed by the method of Lakshmi et al[32]. Apoptotic nuclei exhibits typical changes such as nuclear condensation and fragmentation were stained by AO/EtBr to know the dead apoptotic cells. Cells were treated with PE (30 Gg/mL), PE- AgNPS (20 fig/TlL) and 5-FIJ (30 fig/mL), and incubated in C02 incubator for 24 h. The cells were fixed in methanol: glacial acetic acid (3:1) for 30 min at 37 C. The cells were washed with PBS and stained in 1:1 ratio of AO/EtBr, stained cells were immediately washed and viewed under a fluorescent microscope with a magnification of 40x. 2. 8. Apoptotic DNA fragmentation A poptotic DNA fragmentation is a key feature of rogrammed cell death and also occurs in certain stages of necrosis. DNA damage was estimated by agarose gel electrophoresis of DNA fragmentation[33]. Hep2 cells were treated with PE ( 30 g/m L), PE A g NP s (20 g/m L) and 5-FU (30 Gg/mL). Treated and untreated cells were collected by centrifugation at 3 000 rpm for 15 min at 4 C. The cell pellet was suspended in cell lysis buffer (Tris Hcl 10 mmol/L pH 7. 4, Triton-xlOO, 0. 5%) and kept at 4 C for 20 minutes.

Role of commercial banks in causing the financial crisis Term Paper

Role of commercial banks in causing the financial crisis - Term Paper Example On the other side of Europe, the G7 financial ministers have assumed the crisis to be an American problem until much of the European banking system effectively collapsed. In countries such as Germany, the bailing out of the major industries including the Hypo Real estate as well as European mega banks came to hit them hard as they are the big lenders. Other nations like Britain emulated what was happening and commendably made their banking systems to become national. By October 2008 many of the European countries including Canada had gone so far as to guarantee not only the deposits but as well the debts of the banks as well. The financial system in the world is the umbrella body that will be concerned with how all the institutions that deal with finances will work including the borrowing of money in the form of loans that will be repaid in a period that will be short or relatively longer. At times, the webs of debt and credit have always been fragile in times of panic, spreading problems from a part of the global economy to the other. The reason that is responsible for this is that when one link in the very intricate chain becomes weak and breaks and defaults on some debt, it can leave creditors hazardously short of funds, unable to assure the credit of other firms. In this way, the consequences of one failure can spread throughout the entire economy and hence the entire money market (Roubini and Mihm 117) . There are always marketing risks arising when financial institutions trade assets and liabilities as well as derivatives as opposed to holding them for longer investment, funding or hedging purposes, (Saunders and cornett 184). When this happens, the financial institutions are assumed to directly control the maturities of their assets and liabilities as well as the interest issues are concerned. As interest rates fall, many mortgage borrowers seek to repay their existing loans and refinance at a lower rate.
