Advanced Internet Development - Essay Example The next step after acquiring people to the page is a means of converting and keeping them for long time as customers in order to get value from them. After the website has captured their real customers, it should now come up with a means of retaining them in the website by making them come back even with visitors. There should be potential in doing all these to ensure the website is successful (Read, 2001). Web applications and websites in the recent world come to be the most popular tool that businesses and organizations like to connect with their customers, users, and prospects (Welling and Thomson, 2008). Attacks can occur in these web applications due certain security flaws. These attacks can harm the business by exposing sensitive information of the customers and the business, steal customer’s information and finally ruin the business reputation. Recent studies conducted showed that over 70% of all web applications are vulnerable to security flaws. Most of security flaws occur in the PHP coding (Standing, 2000). Attacks that may occur in web applications include Remote code execution, SQL injection, Format string vulnerabilities, Cross Site Scripting, and Username enumeration. These attacks occur due to somewhat poor programming approach. It is therefore important for web developers and designers to have knowledge on these attacks. These attacks results from factors discuss ed below. Remote Code Execution is where any desired information is retrieved from the web application. This is done when the attacker runs system code on the vulnerable server. The attacker access information and may go undiscovered by the web administrators (Weber, 2004). The attacker may also include any arbitrary files on the web application. An example of such attack is carried when an attack executes such an exploit code. SQL Injection is considered an old approach in web application security but it is still popular with the attackers. Here the attacker retrieves crucial and

The Role of Hamartia in Oedipus the King Essay -- Oedipus the King Oed

The Role of Hamartia in Oedipus the King Literary tragedy has roots that extend two and a half millennia into the past, but throughout this history the genre's defining characteristics have remained the same. At the very core of tragedy lies an uncertainty over the cause of the tragic predicament. The leading candidate for an explanation of this cause often comes under the name of hamartia, a Greek word that translates into "a defect in character", "an error" or "a mistake." However, the most common conception (or misconception) of this notion is that it involves "a moral or intellectual weakness," a view that often leads scholars to regard hamartia as the answer to questions of tragic flaw. Care must be taken in making this assumption since no element in tragedy bears easy explanation and since the exact nature of hamartia itself is impossible to pinpoint.   Ã‚  Ã‚   In this spirit of uncertainty and as Aristotle's conception of the "ideal" tragedy, Oedipus the King revolves around just such an elusive "why". This play, like all tragedies, defies our notions of cause and effect--no single action or fault of the hero could have rightly vaulted him into the intense shame of incest and patricide. In the incessant search for what could have created this downfall, one line of thought gives responsibility for Oedipus' story to the heavy hand of destiny. If this theory is to be believed, his entire life can be viewed as a confirmation of a prophesized fate, much as a reading of the text is a fulfillment of the story we already know. Whether a prewritten destiny dictated the king's actions, or whether he earned this destiny with the faulted life foreseen by the gods, an analysis of Oedipus' behaviors may suggest why he was forced to f... ...sible to call Oedipus' faults an object of Sophocles' exploration. Perhaps, too, the great tragedian sought to illustrate the consequence of such behaviors by associating them with a doomed individual. Though it is difficult to imagine Sophocles offering an Aesop-like lesson, the Greek tragedies always served a civic function to the audience that gathered to view them. Thus it may be reasonable to believe that this drama meant to illuminate the faults that could lead to downfall in the ancient world, and even to caution against them. The unpredictable influences destiny and divinity surely played a role in Oedipus' decline, but just as significant a contribution to the tragic predicament came from his own failings.

Low Cost Strategy Essay

Low cost strategy is one of the three generic marketing strategies. Companies use this strategy to offer low price in its products/services by focusing on various points in its value chain activities. In order to be a successful low-cost competitor in a competitive environment, companies focus on several issues; which all pass from the ways of margin improvement (in terms of increasing revenue and reducing cost) and asset effectiveness (in the sense of minimizing working capital and maximizing winning on asset). In other words, we can say that low-cost competitors focus on efficiency in its all activities by redefining and cutting costs in their value chain. Here are different attributes which low-cost strategy focused companies make or follow in order to be competitive and have sustainable low-cost strategies: †¢ Forming partnership in some activities which is too costly for the company to do by itself and/or outsourcing manufacturing activities to low-cost countries. For example, Huawei Technologies (which is importing and developing PBX telephone products) made partnership with 3Com and Siemens so enter new markets and also by using its some other competitive strengths it outcompetes Cisco (well-known global network manufacturer) within 5-6 years. †¢ Minimizing complex and expensive activities such as, research and development, product design and marketing; and standardizing products and designs. †¢ Having no-extra service but with the best use of asset utilization. For example, Southwest Airlines lowers its costs by no-frill services but also achieve to maximize its profits by returning the plane from the gate to the air within very short time (about 20 minutes). †¢ Combining low-price with product differentiation. For example, Japanese retailer Muji as a competitor to Wal-Mart and IKEA. It is very important for a low-cost strategy focused company to identify and deal with other low-cost competitors as early as possible before they become strong and successful competitor in market. Therefore, companies should consider their external environment especially its competitors in order to be able to become more competitive and gain more market share as a low-cost provider. There are 4 ways of analyzing competitive environment: 1) Identifying company’s low-cost rivals: Possible by detecting and responding potential low-cost competitors on time; based on focusing low-cost strategies against to the company. 2) Performing a total cost analysis: Made by identifying a potential threats from companies which are more efficient in their product and service costs. ) Developing all potential scenarios: Company makes what-if scenarios by clear understanding of the market and competitor’s sustainable capabilities in order to prepare better for future. 4) Determining company’s best strategic moves: In this case company uses its what-if scenario understandings in a way to be able to compete and beat its low-cost rivals. While developing company’s strategic moves to gain higher market share and sustainable competitive edge, managers should develop both short-term tactics and long-term strategies. Short-term tactics allow company to make stronger its strengths and also gain time for the needed analysis to be able to develop long-term strategies while keeping low-cost rivals in a position that does not threats the company. These tactics include offering low-price product/services or providing some other sale incentives, several legal actions such as patent infringement lawsuits, product/service differentiation and lastly focusing more attractive and profitable customers by letting unprofitable ones to rivals. These short-term tactics also, allow company to maintain market share as well as gain sustainability in its actions. Long-term strategies adjust companies to changing market conditions and also allow them to pursue after new market opportunities. These strategies might be riskier than short-terms’ but bring more profits. Long-term strategy includes offering differentiated products, expanding products/services, entering into new geographical areas, becoming low-cost leader or having low-cost subsidiaries, investing in technology and lastly improving customer services. As an example, IBM was selling personal computers as a first mover but then it started to sell differentiated product of software by offering service solutions as well when Dell and Gateway started to sell lower priced personal computers. Overall, in order to be able to successfully compete with other low-cost rivals and have sustainability as a low-cost competitor in the market; Firstly, company must analyze its internal and external environment by defining its own and also competitors’ market positions and potential threats to the company. Secondly, company must be action oriented by using its strengths and competitive advantage to eliminate early detected potential threats for the company in future. Lastly, company must develop a strong plan of action to support its successful competition in the market by entering into the new markets and developing new products on the time and also adapting other necessary tactics as quick as possible.

Habituation of Exploratory Behavior in Rats - Conditioning...

Abstract This study investigated the effects of displaced objects and spatial reorganization on habituation of exploratory behavior. The subjects, rats, each individually spent 5 minutes in an open field for 6 trials. Throughout the study, exploratory behavior was measured in the number of contacts the subject made, the number of ambulations, and contact time (seconds). Trials 1-5 were mainly used to familiarize the subject with its surroundings, naturally leading to decreasing amounts of exploratory behavior. Trial 6 involves the same routine, except displaced objects are introduced in an attempt to renew exploratory behavior and promote the building up of environmental maps and representations. Additionally, the measured behavior†¦show more content†¦In this present study, behavior tests were used in order to determine the likelihood of renewed exploratory behavior in a familiar environment after the introduction of displaced objects. Additionally, renewed exploratory behavior seem s to play a critical role in building environmental maps, leading to the integration of new spatial relationships Poucet et al. (1986). The primary aim of this experiment was to determine if rats would gain a renewal of exploratory behavior due to displaced objects after habituation had settled in. Based on results from these previously mentioned experiments, we hypothesized that subjects were capable of renewing exploratory behavior in a spatially reorganized environment. However, this was under the assumption that complications such as age and species type were inapplicable. Method Subjects The subjects were Sprague-Dawley male rats. Their age is 150 days. The supplier is Harlan Sprague-Dawley. They are maintained on a 12:12 h light/dark cycle and are provided with ad libitum access to food. Apparatus Materials include an open field (OF) apparatus with a 6x6 grid drawn on the inside. Three objects, a coca-cola can, a plastic cylindrical container with rocks inside, and a plastic bear-shaped bottle were used as the objects. Procedure The study period included one week of familiarization and a second week devoted to experimentation.
