An Unlicensed Engineer for Constructing Engineers Case Study

An Unlicensed Engineer for Constructing Engineers - Case Study Example It is evidently clear from the discussion that Charles Landers, unlicensed engineer for constructing engineers forged his partner Henry Wilson’s signature and used his professional seal on at least 40 documents. The falsified documents certified to the Anchorage City Health Department that local septic systems met all city wastewater disposal regulations. No violations of standards except for the forgery and misuse of the seal were reported. The circuit judge Michael Wolverton in his judgment banned Landers for one year from practicing as an engineer’s assistant. Furthermore, he sentenced him to 20 days in jail, 160 hours of community service, $4000 in fines and a year of probation. The judge cited that Landers’ actions constituted a breach of public trust as the public relies on the word of professional engineers to ensure the safety of systems. The first important element is that of forgery of signatures and unauthorized use of an engineer’s seal. This i s not only wrong in engineering but also in other professions where specialized professionals are required to provide their expertise on an issue. This can lead to a destruction of property, loss of lives and reputational damage to the profession among others. The second element is the aspect of canvassing and behaving like a competent engineer while in the real sense one is not. This amounts to deceiving the public for purposes of individual gains, which is unethical as this could still have far-reaching consequences because a violation of standards may be experienced. The third element concerns relationship with fellow engineers such that they are supposed to respect one another in the provision of their services. The relationship is important for personal and also for professional growth.

Relationship between science and Bible Essay Example | Topics and Well Written Essays - 3500 words

Relationship between science and Bible - Essay Example This idea is neither a biblical nor logical inference (Yasri & Mancy 2). The Bible even states it clearly that the earth is by the heavens and not the other way round (Jaki 224). The paper discusses the relationship that exists between the Bible and science. Zigerell (314) explains that the early proponents such as Galileo Galilei, Johannes Kepler and Nicholas Copernicus were all Christians. The famous scientist Isaac Newton stated that the most beautiful system of the planets, comets and sun could proceed only from the dominion and counsel on a powerful and intelligent being (Zigerell 315). Therefore, the Bible and science are closely related. Scientists agree with the physical world described in the Bible. Zigerell (315) asserts that some of the scientific principles described in the Bible in the thousands years ago are (El-Hani & Claudia 103). The Bible and science relate in various ways as discussed below. The bible addresses statements consistent with the astronomy (Zigerell 315 ). The Bible refers frequently to the great number of stars that are in heaven. The book of Genesis talks of the stars (Schroeder 178). In chapter twenty-two, verse seventeen of Genesis book states how God was to bless Abraham. God will bless Abraham abundantly, and he will multiply the descendants of Abraham as the heavenly stars and as the sand that are on the seashore (Zigerell 315). The descendants of Abraham will be able to possess the gates of their enemies. The book of Jeremiah also addresses the issue of stars (Zigerell 316). Chapter thirty three of the book of Jeremiah explains how God was to bless the descendants of His servant David and the Levites who were ministering to him. â€Å"As the host of the heavens cannot be numbered, nor the sand of the sea be measured, so I will multiply the descendants of David My servant and the Levites who minister to me† (Jer. 33:1). The number of stars that are in heaven is not in the two books, but they are to be many (Yasri & Ma ncy 3). Scientists even today admit that they are not aware of the number of stars in the heaven (Yasri & Mancy 3). With the naked eyes, the scientists are only able to account for 3,000 stars. Scientists have estimated the number of stars and seashore sand grains of the earth to be great numbers, but they don’t give the exact values of each (Jaki 225). The Bible states that the stars are unique (Zigerell 316). The book of I Corinthians 15:41 express the uniqueness of each star. The book states that, â€Å"there is one glory of the sun, another glory of the moon and another glory of the stars; for one star differs from another star in glory† (Jaki 226). Scientists explain that all stars look the same when observed with the naked eyes (El-Hani & Claudia 104). The stars seem to be just light points when seen from a telescope. When the light spectra of stars are, it reveals that each star is unique and is different from the others (Yasri & Mancy 3). The movement precision in the universe has in the Bible (Zigerell 317). The book of Jeremiah 31:35-36 describes the movement precision in the universe. Scientists have also explained the movements that occur within the universe (Yasri & Mancy 4). The Bible also describes how the earth is in the space (Zigerell 317).

Critically discuss the contribution of positivism to the study of society - Essay Example This paper would however move forward with narrowing its focus on epistemology, which is concerned about the sources, nature, and limitations of knowledge. Moreover, epistemology also attempts to look at the process of acquiring knowledge, differentiating between reliable and unreliable knowledge, nature of the knowledge and all other factors involved in the process. Epistemologists differ greatly, as they do in all other aspects of philosophy and there are different schools of thought in epistemology as well. Rationalism believes that knowledge comes with reason, thinking, and discovering ideas, knowledge or reality resides in the ideas, and ideas are â€Å"a priori† which come before experience. Empiricism believes that the source of knowledge remains experience and humans only have the access to the ideas of the things and not things. For having the knowledge, we need to use experience. Transcendental idealism is another school of thought, which tries to accommodate both em piricism and rationalism by saying that knowledge is something, which begins with experience and ends at the structural arrangement of knowledge in mind with the use of logic and reasoning. However, there are other schools of thought like intuitionism, authoritarianism, postmodern view and others but we once again narrow down or focus on empiricism since that concerns our rest of the decision. Positivism is one of the most important concepts and developments in the empiricist school of thought, which holds the view that reliable knowledge is only attainable with proper experience and demands verification, very much similar to the scientific way of acquiring knowledge. Famous sociologist and philosopher Auguste Comte deserves all the credit for coming up with a comprehensive framework and layout for this term (Kaines, pp. 16-24, 1880). However, contributions from Hebert Spencer, Emile Durkenheim, and Charles Darwin have also been

Temporary agencies in organisation Essay Example | Topics and Well Written Essays - 1000 words

Temporary agencies in organisation - Essay Example Generally, client organizations divide its workforce between core and peripherals. Core workforces are derived within the organization, while peripherals are obtained outside the organization. Literature indicates those firms are responsible in making the decision on the jobs that should be retained for the permanent employees and tasks to outsource (Booth, Francesconi and Frank, 2002). Outsourced tasks require less organizations skills and knowledge such as routine. Based on this model, firms distinguish core labour in order to reduce turnover of skilled workers. In other words, the addition of the temporary agency staff in a firm helps to make quicker adjustments of the number of staffs when need arises. Therefore, during economic contraction, firms hire the temporary agency workers. The firm will no longer have the need to sack the permanent members of the workforce (Forde, 2000). In addition, the firm may opt to use temporary staffing agencies to reduce the increasing labour costs. Research indicates that most temporary agency workers receive less pay compared to the permanent members of the workforce (Booth, Francesconi and Frank, 2002). However, this may differ between the bottom and top end of the labour market. In addition, firms are able to reduce operation costs by reducing liabilities such as holiday pay sick pay and maternity cover, although this may differ in various countries. In some countries, the temporary agency workers are entitled for payments. Moreover, the use of the temporary agency workers reduces the fixed cost of hiring permanent staffs. Outsourcing some functions allows a firm to reduce their non-core proficiencies. Therefore, the firm has more time to focus on its main functions. The client organizations get opportunity for screening the temporary workers for potential permanent employees at low cost. Hiring core workforce from a pool of temporary staff can be

Beowulf Essay Example for Free

Beowulf Essay In the epic poem â€Å"Beowulf†, the poet presents both the elements courage and cowardice. These elements are very important and show up continuously throughout the poem. Although the poem is mainly about heroic battles, there are also many cowardly acts among the villagers. The poet significantly develops courage throughout the poem. It is shown when Beowulf challenges Grendel to a battle and ends up defeating him. It is stated that Beowulf fought without any armor and still won. Once done with the fight, he is faced with another battle which is Grendel’s mother. After a tough and long fight, Beowulf ends up winning as well. The brave and courageous thing about Beowulf is that he is willing to do anything and fight for his people, he gives it all his strength to save his village. For example, the challenge with Grendel started because he was terrorizing the Danes. Another example of courage in the poem is when Beowulf fights the dragon, it is clear that this is one of his toughest battles but he cares for his people and puts himself in danger. Beowulf accomplishes a lot for the survival of the Danes and the Geats. On the other hand, cowardice is also shown in the poem through Unferth. Unferth does not want to live under the â€Å"courageous† culture that is so popular in many men anymore. By this, he is letting so much happen to his kingdom and doesn’t care. The most coward thing that Unferth does is give away his sword, it was known back then that a virtuous warrior never parted from his sword. Just like Beowulf is very brave, he has his bad moment as well, he doesn’t want to admit that his time has come and that he is too old to fight the dragon. But the people in Geats show cowardice by not helping their king on his battle. Instead, they hide and just watch not even helping their king who has done so much for them. In conclusion, the epic poem â€Å"Beowulf† may have many brave people but it also shows how some throw away their position as king or do not want to fight for their people anymore, as well as the inconsiderate villagers. Both courage and cowardice are very well portrayed in the poem.

Active Chemical Ingredients in Topical First Aid Treatments

Active Chemical Ingredients in Topical First Aid Treatments AN INVESTIGATION ON THE EFFECTIVENESS OF THE ACTIVE CHEMICAL INGREDIENTS IN TOPICAL FIRST AID TREATMENTS AGAINST STAPHYLOCOCCUS AUREUS. Aim The aim of this investigation is to experimentally determine which first aid product and its active ingredients are most effective against Staphylococcus aureus, and to establish how and why the chemical compounds of the active ingredients in each product affected the results. Introduction The idea for this exploration was developed as a result of an experiment and study that were conducted and taught in my medical microbiology class. The specific lesson that caught my interest was focused on the skin flora as well as infection causing bacteria. This, combined with the lab about the effects of specific antibiotics on bacteria as well as my considerable experience with first aid and disaster response skills led me to think about the importance of antibiotics for medication and treatments. I decided that my investigation would concentrate on topical first aid products against the occasionally pathogenic bacteria, Staphylococcus aureus, a member of the skin flora. My choice to pick a ubiquitous bacterium was because I wanted to focus on the more practical implementations of the investigation and could evaluate for myself which first aid product would be most useful in real world applications. Background    This investigation requires background information about the biochemistry or mechanisms of action in specific compounds and the Kirby-Bauer test. These are described below. Kirby-Bauer Test The Kirby-Bauer test or disk diffusion tests allows for scientists to test the antibiotic sensitivity of bacteria. A disk is impregnated with a substance and placed on a petri dish and a zone of inhibition or inhibition zone appears after days or hours after incubation. The inhibition zone represents the area in which the bacteria has stopped growing or has been killed by the antibiotic. The size of the inhibition zone indicates the effectiveness of the antibiotic (the larger the diameter of the zone of inhibition the more effective the substance is). Mechanism of Action in Compounds This investigation focuses on five specific compounds which are active first aid antiseptic or antibiotic ingredients in the products that will be tested. These compounds are: benzalkonium chloride, triclosan, bacitracin zinc, polymyxin B sulfate, and neomycin sulfate. This information will be sectioned into Part A, B, C, D, and E. Part A: Benzalkonium Chloride Benzalkonium chloride is a member of the quaternary ammonium compounds (QACs) which are also known as cationic agents/surfactants. Furthermore, quaternary ammonium compounds have positively charged structures. Thus, the cationic zone of benzalkonium chloride disrupts the intermolecular attractions/electrostatic interactions of the negatively charged cell components, destroys the outer membrane, and ultimately kills the pathogen. Part B: Triclosan Triclosan works to inhibit bacterial growth through its mechanomolecular energy. This mechanomolecular energy is as a result of the ether single-bond rotations on the central oxygen atom. Subsequently, the rapid and fluctuating vibratory movements of the bonds in the molecule disrupt bacterial membranes which easily allow the chemical compound to enter the cells membrane. Once triclosan enters the cell membrane, it binds and blocks the active sites of the enoyl-acyl carrier-protein reductase enzyme (ENR) thus preventing the process of fatty acid synthesis. This fatty acid process is critical for building the pathogens cell membrane and its other vital functions necessary for processes like reproduction. Furthermore, at extremely low concentrations, triclosan can develop into a crystalline form by ring stacking, thus interfering with essential enzymes including the nicotinamide adenine dinucleotide (NADH) coenzyme of bacteria. Figure 1: Figure 1 visualizes the two benzene rings and the central oxygen atom in the Triclosan compound. Part C: Bacitracin Zinc Bacitracin has antimicrobial activity primarily because of its ability to bind to divalent metal ions, in this case the Zn ²Ã‚ Ã‚ º cation, resulting in bacitracin zinc. The Zn ²Ã‚ Ã‚ º ion forms a ternary 1:1:1 antibiotic-metal-lipid complex. This means that the divalent metal ion complex can tightly bind to the lipid C‚†¦Ã¢â‚¬Å¡Ã¢â‚¬ ¦-isoprenyl pyrophosphate molecules of the cell, acting like a bridge between the pyrophosphate and bacitracin zinc. Once the C‚†¦Ã¢â‚¬Å¡Ã¢â‚¬ ¦-isoprenyl pyrophosphate has been compromised due to its inability to dephosphorylate or remove its phosphate (PO43ˆ’) through the pyrophosphatase enzyme and hydrolysis process, the pyrophosphate can no longer transport lipids into the cell-wall. Subsequently, this inhibits the process of cell-wall synthesis and results in the weakening of the cell wall and ultimately leads to bacterial death. Part D: Polymyxin B Sulfate The mechanism of action of polymyxin B sulfate is similar to that of benzalkonium chloride, in that it is also classified as a cationic surfactant. Therefore, like benzalkonium chloride, polymyxin B sulfate alters the external membrane of bacterial cells. Additionally, because of its positively charged amino group in the cyclic peptide region in the compound, it has an electrostatic attraction for the negatively charged lipopolysaccharide layer of bacterial cells and binds to these specific sites. Once these sites have been compromised, the outer membrane of the bacterial cell becomes destabilized and weakened. Figure 2: Figure 2 visualizes the amino group and cyclic peptide region of polymyxin B sulfate which is the primary mechanism of antimicrobial action within the compound. Part E: Neomycin Sulfate Neomycin sulfate is classified as an aminoglycoside antibiotic which means it has an amino group (-NH‚‚) attached to derivatives of sugar called glycosides. Aminoglycosides are highly positive in charge due to the presence of amino groups and have a high electrostatic attraction for the negatively charged outer surface of bacteria. This electrostatic interaction disrupts the membrane of the bacteria due to the displacement of Mg ²Ã‚ Ã‚ º and Ca ²Ã‚ Ã‚ º bridges and creates temporary openings in the bacterial cell membrane. Subsequently, this process causes intracellular content leakage and further increases the antibiotic intake in the bacteria. Additionally, rRNA molecules of bacteria are highly negative in charge because of the presence of phosphate groups. This negative charge has an electrostatic attraction with the positively charged antibiotic and allows the aminoglycoside to easily bind to the rRNA of the bacteria and thereafter inhibits the process of protei n synthesis leading to bacterial cell death. Prediction The initial prediction is that NEOSPORIN ® Original Ointment will be the most effective compared to Bactine Spray and CVS Health Instant First Aid Spray because it is a triple antibiotic and has a greater variety of active ingredients that can kill bacteria. Experimental Procedure and Methodology Variables The independent variables for this experiment are the different first aid products because each product should influence the dependent variable (diameter of inhibition zone). The dependent variable is the size of the inhibition zones because the length depends on what first aid product is used. The controls of the investigation are the incubation time, petri dish, Staphylococcus aureus, method of inoculation, the incubator, and the amount of each drug because they are variables that are kept constant throughout each trial and for each product tested. It is important to maintain the controls throughout all trials so that measurements can be as consistent as possible. Safety and Environmental Ethics It is important to keep in mind the risks and safety precautions before attempting this experiment. These risks include residual bacterial contamination on the skin and burning. It is highly advised to wear gloves or rubber insulator gloves when needed and to wash hands frequently throughout the experiment. Additionally, an environmental ethical consideration must be taken in account because experimenting with antibacterial products can contribute to antibacterial resistance. However, the effects would be negligible due to the small scale size of the experiment. Materials 125 ml of Agar Absorbent bibulous paper Hole puncher Sharpie Ruler (with millimeters) Gloves 12 Petri dishes Incubator @34  °C; set at 4.5 12 strips of Parafilm Forceps Tweezers Large beaker Hot plate Rubber insulator gloves Bunsen burner Strikers Inoculating loop Staphylococcus aureus NEOSPORIN ® Original Ointment Bactine Spray CVS Health Instant First Aid Spray Procedure Heat up 125 ml of agar in a beaker filled with water on a hotplate and wait until the agar is clear all the way through. Use forceps and rubber insulator gloves to remove the agar out of the beaker. Pour about the same amount of agar in each petri dish and wait until the agar sets (5-10 minutes). Use isolated Staphylococcus aureus and a heated and then cooled inoculating loop to carefully swab the culture into the 12 petri dishes. Make sure to go in a zigzag motion and cover all areas. Label each petri dish #1-#3: NEOSPORIN ® Original Ointment #4-#6: Bactine Spray #7-#9: CVS Health Instant First Aid Spray #10-#12: Control Punch at least 12 holes into absorbent bibulous paper. Soak the disks with each of the drug solutions. Use tweezers that have been heated up and cooled down with water to minimize bacterial contamination. Additionally, each time a different product is being impregnated into the disks, reheat and cool the tweezers to minimize cross-product contamination. Place three disks containing NEOSPORIN ® Original Ointment in petri dishes #1, #2, and #3. Place three disks containing Bactine Spray in petri dishes #4, #5, #6. Place three disks containing CVS Health Instant First Aid Spray in petri dishes #7, #8, #9. Leave the remaining three petri dishes with no disks in order to show that the petri dishes have pure cultures of Staphylococcus aureus. Use parafilm to seal all the petri dishes. Flip over all petri dishes and place in incubator at 34  °C on the 4.5 setting (the optimal temperature and conditions for bacterial growth) Measure the diameter of the inhibition zones (including the disk) 48 hours post inoculation with a ruler (in mm) and record data. Repeat all steps for Trial 2 and Trial 3 making sure all conditions are maintained.

The initial aims of the investigation have been reached. The results of the experiment have suggested that Bactine Spray is the most effective against Staphylococcus aureus followed by NEOSPORIN ® Original Ointment then CVS Health Instant First Aid Spray. Thus, the initial prediction was incorrect. Bactine Spray contained 0.13% of benzalkonium chloride and in this investigation had an average length of 16.3 mm for its zone of inhibition (Table 1). According to a study done by Ali Fazlara (a member of the Department of Food Hygiene at Shahid Chamran University) and Maryam Ekhtelat (a researcher at Shahid Chamran University in the Department of Microbiology) found that because Staphylococcus aureus has a highly negative charge on its cell wall due to its slight anionic teichoic acids and peptidoglycan molecules, it allows for the cationic benzalkonium chloride to bind easily to specficically Staphylococcus aureus cell wall and thus block the active sites for essential enzymes to undergo their normal biochemical reactions for the bacterial cell. Therefore, benzalkonium chloride should theoretically be highly effective against Staphylococcus aureus. The data collected seems to support this and underpins the known fact that benzalkonium chloride is bacteriostatic (a chemical agent t hat stops bacteria from reproducing) at low concentrations. The investigation also suggests that NEOSPORIN ® Original Ointment was the second most effective against Staphylococcus aureus compared with the Bactine Spray and CVS Health Instant First Aid Spray. The active ingredients within this first aid product are bacitracin zinc (400 units), neomycin sulfate (3.5mg), and polymyxin B sulfate (5,000 units). NEOSPORIN ® Original Ointment resulted in an average zone of inhibition diameter of 15.4 mm, as shown in Table 1. The possible reason for why NEOSPORIN ® Original Ointment was not as effective against Staphylococcus aureus in this investigation is because of antibacterial resistance to some or all of the active ingredients by the bacteria. Studies have proposed that the isolate primarily found in the United States called USA300 methicillin-resistant Staphylococcus aureus (MRSA), has been increasingly discovered to have been resistant to neomycin sulfate, bacitracin zinc, and polymyxin B sulfate. In this investigation, it can be suggested that CVS Health Instant First Aid Spray, with a concentration of 0.13% of triclosan was the least effective against Staphylococcus aureus. It resulted in an average zone of inhibition diameter of 5.2 mm according to Table 1. A possible conclusion that can be reached based on the results is the increasingly proven theory that Staphylococcus aureus has a progressively high antimicrobial resistance to triclosan. This is due in part because triclosan was the most common active ingredient in over the counter (OTC) products, which contributed greatly to Staphylococcus aureus antimicrobial resistance. As a matter of fact, the FDA banned triclosan on consumer antibacterial wash products because of the health related risks from bacterial resistance. However, some products still use triclosan because it banned to be used in soaps. These conclusions are incomplete and require improvements in order to thoroughly and further confirm the results and achieve consistent values. The addition of more trials would further eliminate any systematic errors that may have occurred such as error when impregnating disks with the products or cross-product contamination. Any instances of random error can be best alleviated by the use of a Vernier calliper (a measuring instrument that is used for measuring diameters) instead of a ruler. The use of a calliper to measure would contribute to higher precision and less measurement uncertainty. Extending the investigation to other normal bacterial skin flora would be interesting to see the extent of the effectiveness of Bactine Spray, NEOSPORIN ® Original Ointment, and CVS Health Instant First Aid Spray on different bacteria.
