CRITICAL ANALYSIS - Essay Example Although, microscopic urine sediment analysis is generally regarded as the gold standard for urinalysis, its flaws are also acknowledged. Besides the problem with interobserver variability and imprecision, this method is also labour intensive and very time consuming (Langlois et al., 1999). While the culture method is the preferred method of detecting and quantifying bacteria in urine (Graham and Galloway, 2001), non-culture tests include Gram staining of uncentrifuged urine specimens, Gram staining of centrifuged specimens, or direct observation of bacteria in urine specimens, Nitrite test, leukocyte esterase tests etc. Suprapubic aspiration is generally considered the best method to avoid contamination of specimen, however, this method is rarely used because it is invasive and thus uncomfortable and dangerous (Wilson and Loretta, 2004). Semi-automatic equipments like the Yellow IRIS, followed by the UA-1000 and UA-2000 (Sysmex Corporation, Kobe, Japan) were early attempts at automation of urine analysis. With the Yellow IRIS, precision and sensitivity is reported to be considerably better as compared to visual microscopy, especially at the lower concentration range. The Yellow IRIS device after removing mucus strands from native urine, adds a dye and the stained urine is passed through an optical pathway. A strobe lamp interrupts the motion of the fluid and the particles in it are captured on a colour video-camera. The resulting images of the particles are differentiated with respect to their lengthwise dimensions and then presented for validation by a trained analyst. UA-1000 and UA-2000 follow the same principle, but provide better image resolution compared with the Yellow IRIS because the particles are captured by a colour CCD camera Several studies evaluating and/or validating these automated urine examination methods have been carried out and published. From its findings, a few authors concluded that though the UF-100 might not be seen as a

Cyber Crimes - Essay Example The first of these that will be discussed is that of piracy. Although piracy has traditionally been viewed as a problem that is specific to a young generation of music down loaders and video game players, the fact of the matter is that the market for software, video, music, and data piracy has exploded within recent years and is a multi-billion dollar a year loss for the industries whose intellectual rights are being infringed upon. Moreover, if the firm in question is one that distributes or creates a software product, their overall revenues are in dire danger of being lowered as a result of the actions of pirates. Likewise, the firm must be aware of the fact that software piracy usually takes place from within first as an unscrupulous employee having access to the information in question usually is responsible for taking this information home on their own and uploading it to any number of a host of sites as a means of beginning the snow-ball effect of data piracy. As such, one of t he ways in which a firm can seek to ameliorate the way in which it is exposed to the risk of software piracy is to ensure that all data movements within the firm are well tracked as well as having a robust legal department that operates in close concert with the human resources department to ensure that limited numbers of the employees have access to the finished product and those that do are well accounted for and have been explained to the ramifications, both ethical and criminal, with relation to stealing the company’s product. Secondly, if the firm itself is not one that relies on the development of software as a means to earn its revenues, the firm will need to be responsible for the ways in which its employees download and utilize the data that they might find on the internet. For this reason, a robust internet usage policy must be delineated to the employees upon their employment and watch groups should be established to ensure that compliance is met at every step of t he process. The second issue that relates to cyber crimes is that of cyber terrorism. Although this is of course a lower level incidence than the one that has been thus far mentioned, it is of primary importance not only to governmental instruments but to the very foundations of a nation’s economy. Therefore, the threat of cyber terrorism can include any and all firms that deal with an entire litany of different industries and/or businesses. In order to guard against the threat of cyber terrorism, it should be the goal of the firms in question to seek to review their security policies in dept on a quarterly and yearly basis as a means of ensuring that key oversights are addressed and no blatant flaws are exhibited in their systems. Even though it is never possible to ensure that a given firm will be 100% secure from cyber terrorism, the engagement of key assets to review the security procedures is integral in protecting the firm from such an eventuality. Finally, this analysi s will discuss the threat of fraud. This is perhaps the easiest of the three to seek to prevent as it involves the instruction of shareholders with regards to how to interpret threats that present themselves on a daily basis. Furthermore, with respect to fraud, this is almost always the type of situation in which employee lack of knowledge
