Implementing and evaluating my e-Learning design model in my workplace Assignment

Implementing and evaluating my e-Learning design model in my workplace - Assignment Example As a producer of information, every professional is expected to be able to share the information and ideas they have produced in their course of work. As consumers, they expect to have an easy way to access the information that has been produced by others in the same profession. This applies to all types of professions. Teachers are no except from this need of information production and sharing. In fact, this need to produce share and information and collaborate is highly necessary for teachers, regardless of the subject they are teaching (Cowen, 2014). As part of the Arabic teachers’ community, I have identified a need to have collaboration and sharing system for Arabic teachers. As a result of this, I have in the past come up with the design which when implemented will help in teaching Arabic teachers to share their ideas and to build each other. The following is an implementation and evaluation of the design I have designed in the past. The system is designed to aid learning and sharing of ideas. The system is geared towards helping teachers who are engaged in teaching Arabic to high school students. The system must be able to meet some pedagogical principles in order to aid in helping the teachers to not only share the knowledge but also to be able learn from the system. It must be able to motivate the teachers in using the system to enhance the system. The system is not going to be useful unless and until the system is used by the teachers. For this to to be a reality, the system should be easy to use, and must prove its self useful to the users in order for them to find it useful. This means that the system must be intuitive which means that the users must be find it easy to learn how the various components work and how they can navigate the system (Klopotek, 2002). It must also be able to act as a knowledge management system which means that it will be able to

Microbial physiology and culture (Practical Oxygen Transfer in a Essay

Microbial physiology and culture (Practical Oxygen Transfer in a Stirred Tank Reactor) - Essay Example In this experiment, this method is used in the determination of KLa. This process is important since it is applied in many fermentation processes which undergo aerobic reactions. This allows meeting the necessary metabolic demands of aerobic microorganisms. In this process, air is passed through a reactor at a constant flow rate at given speed in revolutions per minute. From the data, CL and time, it’s able to calculate KLa using the formula. Drawing a graph of  against time produces a straight line whose gradient is KLa (Karimi, 2013). Question 1 RPM = 200 From the graph, Thus M=0.0594 KLa=3.564 RPM at 400 From the graph, Thus Therefore the slope, m=0.0146 Thus, KLa = 0.0146*60 = 0.876 h-1 RPM at 600 From the graph, Thus Therefore the slope, m=0.0343 Thus, KLa = 0.0343*60 = 2.058 h-1 RPM at 800 From the graph, Thus Therefore the slope, m=0.0344 Thus, KLa = 0.0344*60 = 2.064h-1 Second practical Flow rate 0.5 Rpm 500 From the graph, Thus Therefore the slope, m=0.0114 Thus, KLa = 0.0114*60 = 0.684h-1 Flow rate 1.50 Rpm 500 Start air concentration 5.7 From the graph, Thus Therefore the slope, m= Thus, KLa = *60 = 2.07h-1 Flow rate 2.0 Rpm 500 Start air concentration 5.7 From the graph, Thus Therefore the slope, m= 0.0594 Thus, KLa = 0.0594*60 = 3.564h-1 Question 2 KLa F N Log KLa Log N 3.564 1 200 0.551938 2.30103 2.058 1 600 0.313445 2.778151 2.064 1 800 0.31471 2.90309 Since Log KLa= y log N + constant From the graph, The equation y=-0.4234X + 1.5199 Therefore the constant y=0.4234 KLa F N Log KLa Log F 0.684 0.5 500 -0.16494 -0.30103 2.07 1 500 0.31597 0 3.564 1.5 500 0.551938 0.176091 Since Log KLa= X log F + constant From the graph, The equation y=-1.5127X + 0.2973 Therefore the constant x=1.5127 Question 3 Factors affecting KLa in STR: 1. Culture Conditions 2. Operation of the fermenter 3. Impeller Design Question 4 Increase in the values of the above stated factors reduces the time for the dissolved oxygen concentration. Question 5 Why KLa ra ther than KL It is extremely impossible to measure KL alone. Therefore, to make KL measurable it has to be combined with a to form KLa (Volumetric mass – transfer coefficient) which is easier to determine Question 6 Polarographic oxygen electrode measure Polarographic system is used to measure dissolved oxygen. In this system, the measurement device known as a transducer is the Clark oxygen electrode. An oxygen monitor is the processing (coupling Device) and the recording device is a computer aided data system. Question 7 Importance of KLa KLa is important since it facilitates establishment of efficiency and also it helps in quantifying effects of operating variables that has to be applied on the provision of oxygen. Question 8 Techniques of determining KLa Sulfite oxidation technique In this process, the Oxygen transfer rate is determined by the oxidation of sulfite solution. Gassing-out techniques In this process, the estimation of KLa is done by monitoring the increase of dissolved oxygen in during the process of aeration and agitation. Question 9 From the graphing and the trend of the graph, it can be determined that as the agitation speed increases, the time taken for the dissolved oxygen to reach dissolved oxygen concentration is shortened.

(whatever you want) - Essay Example But the 21st century may see the end of this global system. The peripheral regions have been exploited, and new powers and systems are rising up to challenge the established order, namely religious fundamentalism and the failed state. With a lack of new regions to exploit, the primacy of the United States will wane as these other competing powers gain momentum. In the article, â€Å"In U.S. Visit, Brown to Urge ‘New Deal’†, (Sullivan, 2009) we read of Prime Minister Tony Brown’s visit to the United States to visit President Barak Obama. They are there to discuss the global financial crisis that their countries find themselves in. They pledged to cooperate with the other Group of 20 (G-20) countries that have all seen considerable amounts of capital and supposed wealth disappear over the past year. This article exemplifies this theory because the whole meeting is concerned with returning the global economy to a status quo, namely the continuation of concentration of capital in the United States and the other strongly capitalistic countries of the world. Talk centered exclusively on stimulating the economies of the G-20 nations while nations on the fringe of the core capitalistic nations were

Land Law - Essay Example Therefore, it is important to now that Under (Law of Property Act 1925 s 199(1)(ii)(a)), the occupant(s) of the property have major interests ‘since it is implicit in Williams & Glyn’s Bank v Boland [1981] AC 487, Midland Bank v Dobson [1986] 1 FLR 171 and Lloyds Bank v Rosset [1991] 1 AC 107 that the beneficial interest (of the third parties) under this trust precedes the court order’ (Milney, 1997). It is an important consideration that belief involved in proprietary estoppel cases can be in any rights in and over the property. Tom, another third party, through a properly executed deed, was given exclusive possession over a cottage in the property for a period of six years. In simpler words, the said cottage was given on lease to Tom by the sole registered owner, Simon. The deed is a legal contact between the two parties with specified terms and conditions. The contractual obligations are legally binding on the two parties. When the property is transferred or sold to another person, the liabilities and other encumbrances, unless discounted, are also carried forward, without affecting the rights of the people, especially those who are leased part of the property through proper legal deals. According to LRA 2002(c.9) Section 12(8), ‘registration with possessory title has the same effect as registration with absolute title, except that it does not affect the enforcement of any estate, right or interest adverse to, or in derogation of, the proprietor’s title subsisting at the time of registration or then capable of arising’ (www.opsi.gov.uk). Simon had also given right of way over his driveway to his neighbour Nora, for ‘as long as you live’. This law of easement primarily provides a right to use a piece of land by the neighbours for performing specific functions. The most popular easement is ‘right to

Impact of Exposing Personal Data Research Proposal

Impact of Exposing Personal Data - Research Proposal Example Customers provide information online due to many reasons, but most importantly, they provide information mostly on the website. Due to the lack of technology and measures of customer personal privacy, online businesses fail to protect their database by security breaches conducted by hackers or cybercriminals. The data including all the personal information of the customer is breached resulting in exposure of thousands of authentic customer personal information and financial status. In order to conduct a security breach on the web server, cybercriminals use the Internet, as a carrier along with intelligent codes that are purposefully constructed to extract confidential information, the most favorable point of attack is the web server. The information that is provided online by the users is gathered in a database that is connected to the web server. Hackers and cyber criminals deploy various methods to attack web servers in order to extract information that is stored in the database. D ue to this reason, business suffers severe losses from data theft issues as in 2009 investigators related to data breach reported from Verizon business that crooks nabbed 285 million records. (Larkin 2009) Peter Tippett, who is the author of the report and vice president of innovation and technology with Verizon Business, says that the report includes all the IP addresses associated with the account that is used in the thefts, and criminals are identified only because of in-depth investigations by collaborative support of law enforcement agencies including FBI and Scotland Yard,. From this particular report, 90 security breaches were studied out of which 68 were reversed for further investigation to a specific IP address and location. The conclusions highlighted Eastern Europe as a common source followed by East Asia and North America (Larkin 2009). 1.1 Social Networking Sites Moreover, social network sites are another domain that is of prime concerned, in the context of exposing pe rsonal privacy. People are spending an enormous amount of time on these websites, and are becoming habitual of online communication, which portrays a negative impact on face-to-face communication. The teenagers are not aware that the information and published material including pictures can be retrieved even after deletion from the social networking site. By oversharing, personal information may attract cybercriminals, burglars and even employers who can evaluate values of a person by reviewing comments on the site that may compromise the individual to lose his job. There is no credibility of the user authentication of what they are claiming to be on social networking sites. Users trust textual communication from these social networking sites more than emails. The security of these websites can be compromised anytime and can publish communication or personal pictures on the web if breached.  

Evaluate costa customers service approach through observation and a Assignment

Evaluate costa customers service approach through observation and a Mystery shop (report ) - Assignment Example The report outlines the â€Å"push and pull† theory as a method of addressing customer concerns; it further evaluates the validity of this approach in handling customer issues in modern day business environment that is getting increasingly competitive. This theory is applied in supporting my arguments that place customer care as a vital component of business processes. The relationship between good customer relationships and business success is explored with an aim of giving you the justifications for adopting a customer oriented strategy that contributes to overall business sustainability over time. Customer service training is vital in making the employees responsive to customer needs and in establishing it as part of the firm’s culture. If a firm owner wants to be successful in achieving the objectives set forth, then customer service is of paramount importance because positive responses increase client numbers. In Adam Smith’s basic theory of competition, he says that businesses need to be very involved in this initiative to satisfy individual customer needs. Clients treated in a humane way and in a respectful manner have a high chance of coming back to the premises. Costa Coffee is a business outlet in the hospitality industry; this is a highly competitive field with new shops opening at city corners every day (Brody, 2009)1. In order to remain competitive in this growing field, customer relationship building initiatives is therefore of vital importance to keep them coming. This is enhanced by offering them the best services at a reasonable cost and maintaining a feedback mechanism that ensures their specific needs are met. For instance, coffee is available in a variety of grades and types; we have the Arabica and Robusta coffee varieties which also have different tastes. Giving clients these brew options provides a one stop shop where different taste needs are met. We used

Investigating arson and bombings Essay Example | Topics and Well Written Essays - 500 words

Investigating arson and bombings - Essay Example In a preliminary investigation, an investigator should be searching for two things once the fire has been extinguished: the point of origin and the cause of the fire. The point of origin is where the fire began; it is easier to determine the cause of the fire once the point of origin is discovered. For instance, the presence of combustible materials far away from an electrical outlet could indicate the point of origin and a candidate for the cause of the fire. In addition, the United States Justice Department recommends that arson investigators, upon arriving to the scene, mentally note evidence at the scene, recognize threats to evidence, and protect evidence from threats. Part of the advantage of arriving on the scene of a potential arson is the identification of the color and height of smoke and flames. The intensity of the fire and the role that accelerants played in starting it can be inferred from the nature of its flames. Depending on the temperature, flames range from red to yellow to blue to white. According to Burke (2006), normal flames tend to burn with a combination of yellow and orange; generally, hydrocarbon accelerants produce a yellow-to-deep red flame and deep red flames with dense black smoke indicates petroleum products. By arriving at the scene early enough, the arson investigator can visually observe these signs of accelerants and infer additional clues. In addition, the flame and smoke of arson cases also gives clues to the other senses, including the sense of smell. The seasoned arson investigator should be able to recognize the scent of accelerants. Gasoline and kerosene, for instance, have noticeably different smells. The investigator should also be able to distinguish between paint thinner and lacquer, which are common accelerants used in arson cases. These various scents are given off and carried when they fuel a fire. Evidence comes in a number of forms. Primary evidence includes direct, material evidence of a crime
