Art, Science, and a Balanced Life essays
Art, Science, and a Balanced Life essays One of the things that differentiate the human race from other forms of life is our ability to reason. The uniqueness of each individual, however, causes us to reason in different ways. An individual's reasoning can be categorized into two primary groups: reasoning based on emotion and instinct versus reasoning based on logic and concrete facts. These two categories are sometimes known as art and science, respectively. It is commonly believed that "Art upsets, while science reassures," however further philosophical analysis questions this, by examining "Science reassures, while art upsets" as an equally valid statement. Although both art and science are branches of knowledge that have the ability to simultaneously reassure and upset, they use different approaches in their formation. Art is the spontaneous documentation of emotions based on one's own perception of life. This is contrasted with science, which is a systemized process involving observation and experiments that results in the formation of a hypothesis leading to a theory. Science that is at the foundation is systematized, based on logic, and has a set structure. The laboratory science, however, can be messy and tentative, complicating the question of whether science upsets or reassures. A scientific fact can be fully explained, leaving nothing to chance or imagination. It is interesting to note that the famous quote, "Art upsets, science reassures", was made by the French sculptor, painter, and designer, Georges Braque. The difficulty one experiences with art is its inability to be explained due to its basis on feelings experienced by no two individuals. Art is upsetting because one cannot convey the exact picture or feelings that he has towards a piece of art. Ironically, in the words of Braque, "There is only one valuable thing in art: the thing you cannot explain." A feeling of discouragement is often felt when you cannot explain the beauty you see, instead, others m...

The requirements of the Defense Industrial Security Program (DISP) would apply to which of the following contracts? Classified. The major determining factor in deciding if information qualifies as contractor bid or proposal information or source selection information is that it contains information that has not previously been made available to the public. Which of these is not an example of contractor bid or proposal information? Cost or technical evaluation of proposals. How is source selection information marked? Mark the cover and each page containing information ;Source Selection Information-See FAR 3.104.; Services of a type offered and sold competitively in substantial quantities in the commercial marketplace for tasks performed under standard commercial terms and conditions can be considered commercial items if they are based on established catalog or market prices for specific tasks performed. For acquisitions estimated below the simplified acquisition threshold (SAT), market research must be done when adequate information is not available and the circumstances justify the cost. Simplified acquisition procedures (SAP) may be used for the acquisition of commercial itemsup to a maximum of $5,000,000. What factors affect the amount of market research conducted? Urgency, complexity, estimated dollar value, and past experience. If you determine that the requirement in a purchase request meets the definition of a commercial item and the item is customarily available in the commercial marketplace, what part of the Federal Acquisition Regulation (FAR) should you consult for procedures for the solicitation and award? 12 The contracting officer (CO) must always ensure the final description in a purchase request specifies needs using market research in a manner designed to do all of the following except include restrictive provisions or conditions. Who is responsible for the final description of need used in a solicitation? Contracting officer. Supplies and services identified in a purchase request must be stated in terms of functions to be performed, performance required, or essential physical characteristics. All of the following should be included in a ;brand name or equal; purchase description except a request for bid samples of brand name specified. What requirement may be used in place of ;minimum needs of the government; to get the best value for your customer and increase competition? Performance target. Unnecessarily short or difficult delivery schedules tend to restrict competition. The government may recoup some or all of its probable damages caused by delayed delivery or performance of the contractor by invoking the liquidated damages clause. FAR Subpart 4.8 establishes procedures for maintaining contract files to ensure uniformity from one activity to another. Why is this important? Ensure all documents regarding contract actions are kept in conformance with agency regulations for file location and maintenance. Which types of copies of contractual instruments can become part of the official contract file? Original, authenticated copies, and conformed copies.

A special form of written approval by an authorized official that is required by statute or regulation as a prerequisite to taking certain contracting actions is known as a determination and finding. Each determination and finding shall set forth enough facts and circumstances to clearly and convincingly justify the specific determination made. The approval granted by a determination and finding is restricted to proposed contract actions described in that determination and finding. What is the first required source of services for federal agencies? JWOD participating nonprofit agencies. General Services Administration (GSA), Defense Logistics Agency (DLA), and the Veterans Affairs (VA) are all examples of what type of supply source? Wholesale. One of the biggest advantages to purchasing items estimated at less than $2,500 from a Government Services Administration (GSA) contract is that the price has already been determined fair and reasonable By establishing an indefinite delivery contract, you are allowing for prepriced deliveries of items under contract. The terms and conditions of an indefinite contract delivery order are established by the terms and conditions of the basic contract. What information may be used to ensure that small business concerns are given opportunities to respond to solicitations issued using simplified acquisition procedures (SAP)? Business status information from the source list. Acquisitions estimated at what dollar amount are reserved exclusively for small business concerns? Exceeding the micro-purchase threshold, but less than the SAT. If the contracting officer receives only one acceptable offer from a responsible small business concern in response to a small business set-aside, what action should the contracting officer take? Award to the responding small business. If the contracting officer suspects, or has information to indicate, that the price received from a contractor on a micro-purchase may not be reasonable, the contracting officer should take actions to verify price reasonableness. For purchases exceeding the micro-purchase threshold, but not exceeding the simplified acquisition threshold (SAT), what procedures may the contracting officer elect to use? SAP, sealed bidding, or negotiations. When must contracting officers use the government-wide point of entry (GPE) to solicit? When soliciting purchases exceeding $25,000.

Streamlined synopsis/solicitation procedures may be used for acquisition of commercial items using a written solicitation. The contracting officer may establish a response time of less than 30 days when issuing a synopsis/solicitation for items not expected to exceed the SAT. Public law requires that contracts for the acquisition of commercial items shall, to the maximum extent practicable, include only those clauses required to implement provisions of law or executive orders, or those clauses determined to be consistent with customary commercial practice. Because of the broad range of items acquired by the government, the variations in commercial practices, and the relative volume of the government;s acquisition in specific markets, contracting officers may tailor provisions to adapt to the market conditions for each acquisition. How is tailoring accomplished? By addenda to the solicitation and contract. If only one reply is received in response to a solicitation estimated at less than the simplified acquisition threshold (SAT), what action must the contracting officer take before making the award? Include a statement in the contract file giving the basis of the determination of fair and reasonable price. What may be used in lieu of obtaining individual quotations each time a purchase for the same item is contemplated? Standing price quotation. When, in response to a solicitation for commercial items, a contractor proposes more than one product that will meet a government need, the contracting officer shall evaluate each product as a separate offer. It is not necessary to describe the relative importance of evaluation factors when using simplified acquisition procedures (SAP) of FAR Part 13. If the government issues an order resulting from a quotation, when may the government withdraw, amend, or cancel its offer? At any time before acceptance occurs. ; If a contractor has been excluded from government contracting for a reasonable, specified period of time because of conviction on a criminal offense in connection with obtaining a public contract, that contractor is considered to be debarred.

To the maximum extent possible, purchase orders for commercial items should include only those clauses required to implement provisions of law, or executive order, and those clauses that are determined to be consistent with prevailing commercial practice. Which clause must be included in an unpriced purchase order? Notice to Supplier. Under a blanket purchase agreement, the government is obligated for authorized purchases only. The contracting officer shall ensure that each blanket purchase agreement is reviewed at least annually. It is not mandatory for all blanket purchase agreements to contain an approved price list with specific items. How many days written notice must a contractor give to the government to cancel a blanket purchasing agreement? 30 days. Under fast payment procedures, payment is made before verifying receipt and acceptance but after invoicing. The government can exercise its right to the option period during the current performance period. Options are evaluated by adding the total price for all options to the total price for the basic requirement. What types of contracts are authorized for the acquisition of commercial items? Firm-fixed-price and fixed price contracts with EPA. Which is not an accepted price adjustment type used with a fixed-price contract with economic price adjustment? Price averaging. Which type of contract should be used to procure precious metals? fixed-price with economic price adjustment. The contract price of a fixed-price contract with economic price adjustment may be revised a. downward only based on negotiations. upward and downward within the limitations of the clause. A definite-quantity contract may be used when it can be determined in advance that a definite quantity of supplies or services will be required during the contract period and the supplies or services are regularly available or will be available after a short-lead time. When the government cannot predetermine (within stated limits) the precise quantities of supplies or services that will be required during the contract period, the contracting officer would use aindefinite-quantity contract. indefinite-quantity contract. When an indefinite-quantity type contract is being used, performance or deliveries are scheduled by placing an order with the contractor. The contract must clearly define the requirements for the contractor;s control of quality for the supplies or services to be acquired; however, no contract may preclude the government from performing inspections. Unless specifically reserved, responsibility for performing all inspections and tests as required by the contract rests with the contractor. If supplies or services are rejected as nonconforming, notices of rejection shall be promptly furnished to the contractor and will include reasons for rejection. Ordinarily, what option is given to the contractor because of a notice of rejection for nonconformance? Correct or replace any nonconforming supplies at no additional cost to the government. Why are contractors required to mark supplies, or otherwise furnish notice with the supplies, of the existence of the warranty? Inform government personnel who store, stock or use the supplies. The implied warranty of merchantability provides that an item is reasonably fit for the ordinary purposes for which such items are used. The Federal Acquisition Streamlining Act (FASA) requires that contracting officers take advantage of commercial warranties offered to the maximum extent practicable. The principle purpose of a warranty is to delineate the rights and obligations of the contractor and the government for defective items and services and to foster quality performance. A contract action that changes or alters the agreement between the parties of a contract is called a modification. Who has the authority to execute contract modifications on behalf of the government? Contracting officers acting within the scope of their authority. Requests for follow-up should be generated by the requesting activity when the supplies or services have not been received by 1300 hours of the sixth day following the scheduled delivery date. When a contractor has failed to make delivery or cure a delinquency, and has not justified the delay, the contracting officer should take appropriate action to cancel or terminate the order if in the government;s best interest. Which one is not considered an administrative error? Obvious errors in the unit price. If the contractor has yet to deliver or begin performance on an order and you need to make a change not affecting cost of the item or delivery, to what type of agreement should you attempt to have the contractor agree? No cost change to the contract without modification. The two types of contract modifications are unilateral and bilateral. Unilateral modifications are allowed for no cost amended shipping instructions to a unilateral purchase order and for any change made before work begins if the change is within the scope of the original order. Which action should a contracting officer take to accomplish an administrative change? unilateral modification. A contractor has notified the contracting officer of the intent not to accept a unilateral purchase order. In this situation, the contracting officer must proceed with cancellation of the order. The termination of acquisitions of commercial items is covered in Federal Acquisition Regulation (FAR) Part 12, with FAR Part 49 as guidance. The contractor shall be liable to the government for all rights and remedies provided by law if the contract was terminated for cause. Under the Contract Terms and Conditions-Commercial Items clause, the contractor is required to notify the contracting officer of an excusable delay as soon as possible after commencement of an excusable delay. A cure notice notifies the contractor of a specific condition that the government considers to be endangering performance of the contract. When termination is for the government;s convenience, what may a contractor use to demonstrate charges resulting from the termination for which the contractor is entitled to be paid? Records from the contractor;s standard record keeping system. When does the government have the right to terminate a contract for default after issuing a cure notice and the contractor has not corrected the failure? 10 days after receipt of the cure notice. Instead of terminating for default, the contracting officer has several options. This does not include Instead of terminating for default, the contracting officer has several options. This does not include The contracting officer has grounds to terminate a contractor for default when there is an actual failure or fails to progress to perform contractual obligations. When supplies or services are still required after termination for default, the contracting officer should repurchase the same or similar supplies or services against the contractor;s account as soon as possible. Contract files using simplified acquisition procedures are considered closed when the contracting officer receives evidence of receipt of property and final payment. Data transfer, storage, and retrieval procedures must record and reproduce the original document completely, accurately, and clearly. In addition, the procedures must protect the original data from alteration.

Contemporary leadership issues - Assignment Example The third issue is difference between what science knows and what business does, in which he concludes that organizations make decisions that are based on assumptions that are outdate, unexamined, and rooted more in folklore that in science (Pink). A fourth issue is brought out by another speaker, Sir Ken Robinson. The issue is that schools are killing creativity by stigmatizing mistakes, which learners have to make in order to be ultimately accomplished. The fifth issue is schools train people to be what they want them to be, as opposed allowing them to learn to become what they wish to become, which kills they creative capacity (Robinson). Sixthly, modern education systems brought to meet the needs of industrialism, have brought academic inflation ââ¬â better leadership through education should be focused on the diversity of talent. Seventh is that modern leadership does not appreciate the dynamism of intelligence. The eighth, coming from Simon Sinek, is outside-in organizational communication (guided by ââ¬Å"whatâ⬠), as opposed to inside-out communication (guided by ââ¬Å"whyâ⬠or purpose) (Sinek). Pursue the purpose, not the result. The ninth point is about hiring people who believe in the same thing as the organization, not because they need money. Finally, it is the understanding that driving potential is more important financial

Othello Essay Example | Topics and Well Written Essays - 1000 words - 3
Othello - Essay Example ful reevaluation of the play points to the fact that the ultimate victim in this classic play by Shakespeare is not Desdemona but Brabantio ââ¬â Desdemonaââ¬â¢s father. Brabantio, a Venetian Senator, awoke one night from a commotion brought about by Iago and Roderigo as they notify him that Desdemona has absconded with the "black ram" or "Barbary horse," or Othello. The two men tells the senator that the "lascivious Moor" has taken Desdemona and she has "made a gross revolt,/ Tying her duty, beauty, wit, and fortunes/ In an extravagant and wheeling stranger/ Of here and every where (1.1.126-137)." When sense that his daughter is not in her bed, he ensues to place the culpability on his daughter and likewise blames Othello. Most critics would argue that Brabantio should have blamed himself more that anyone else (Hageman 67). On the other hand, Brabantio is deceived by the two, eloping without his consent. Brabantioââ¬â¢s sensibilities are injured by this act as first, he is a respected senator in Venice, and second, he is the father of a girl who ran away with a person he considered friend. Embarrassed and furious, Brabantio anxiously cries out t o Roderigo, "O unhappy girl!--/ With the Moor, sayst thou?--Who would be a father!--/ How didst thou know twas she?---O, she deceives me/ Past thought!......O treason of the blood!/ Fathers, from hence trust not your daughters minds/ By what you see them act (1.1.163-171)." Brabantioââ¬â¢s initial reaction demonstrates fury as he suffers betrayal from Desdemona, the daughter he adores. The words "treason of the blood" are particularly significant as they propose not only an act of unjustifiable trickery but also a profundity of fervor for his daughter ââ¬â which in effect, a trickery he fails to grasp. Eventually, he illustrates Desdemonas temperament as "A maiden, never bold;/ Of spirit so still and quiet that her motion/ Blushd at herself (1.3.94-96)." Brabantio asks himself how the two are able to deceive him. Failing to

Synthetic Rubber Lab Report Example | Topics and Well Written Essays - 1500 words
Synthetic Rubber - Lab Report Example During polymerization the double bonds of the isoprene monomers give way to single bonds which will lead to further increase in length of product chain. Butyl rubber-also known as polyisobutylene (C4H8)-is a synthetic rubber and is produced by polymerization of about 98% of isobutylene with about 2% of isoprene (Wikipedia, 2006) using BF3, H2O, CH2CL2 as reaction activators under -78C temperature. e.g Similarities and Differencies: In both natural and synthetic rubbers production, the monomers can be mixed in various desirable proportions to achieve a wider range of physical, mechanical, and chemical properties through the use additive. The formation of natural and synthetic rubbers are three step Free radical eliminations and substitutions reactions. Both Natural and synthetic rubber reactions require protectants against deterioration during the coagulation and drying (CIWMB). 2. In its natural form rubber is too soft to be used for any useful purposes.Natural rubbers tends to be sticky and soft at high temperatures; while at low temperatures they are brittle and stiff, making them difficult to process. This is due to a high degree of entropy. Therefore, its properties were improved using special processing techniques. During vulcanization, or curing, of rubber, individual polymer molecules are linked to other polymer molecules by polysulphide

High Level Design (HLD)
High Level Design (HLD) High level design High level design (HLD) gives the complete system design of functional architecture and database design. For the developers it is very much important to understand how the flow of the system is. In this phase the system design team testers team and the customers plays an important role. For this entry criteria are required the document that is SRS and the then exit criteria will be high level design, projects standards, functional design documents, and the database design documents. Problem specification Data has to be processed in a effective and efficient way. Time consumption should be less. Easy to implement. Data Definition/ Dictionary Data dictionary is a repository that contains all the description of all data produced by the application.

The user must be aware of the government rules and regulations that are to be implemented on the terms. The user must be aware of the flow at which the process of system takes place. Low level design Low level design (LLD) is like detailing the High level design. It defines the real logic for each and the each every component of the system. Class diagrams with the methods and relation between the classes comes under the low level design. The main phase of the object oriented approach is as follows:- Object modeling Dynamic modeling Object modeling Object modeling technique describes a method for the analysis, design, and implementation of a system using an object-oriented technique. Object modeling technique consists of four phases, which can be performed iteratively are Analysis, system design, object design, implementation Dynamic modeling The dynamic model describes the functionalities involved in the project and the person performing those functionalities. Following are the different kind of dynamic diagrams namely; Use case, Sequence, Activity diagrams. Use case diagram Ause case diagramis the simple and it is a represented as the userââ¬â¢s interaction with the system and describes the specifications of ause case. A use case diagram can represent the different kinds of users of a system and the different ways that they will interact with the system. Such diagrams is typically used in conjunction with the textualuse caseas well as it will often be accompanied by other kinds of diagrams. It is the high level piece of functionality that the system provides. An actor is one who interacts with the system. This Use Case diagrams are included into two modeling languages defined by the Object Management Group (OMG). Both the UML and SysML standards define a graphical notation for modeling use cases with diagrams. One complain is that they will not define the format for depicting these use cases. Generally both the graphical notation and the descriptions are very important as they document the use case and it is showing the reason for which an actor uses a system. The use case diagram shows the place of use case with the other use cases. As organizing the mechanism a set of consistent and coherent use cases promotes important figure of system behavior and have a common understanding between the customer or owner or user and the development team. Sequence diagrams Asequence diagramis a kind ofinteraction diagramthat shows how processes is operated with one another and in what order the processes is operated. It is the construction of aMessage Sequence Chart. A sequence diagram shows how the object interaction is arranged in time sequence. It describes the objects and classes which is involved in the scenario as well as in the sequence of messages that has been exchanged between the objects and it is needed to carry out the functions of the scenario. Sequence diagrams are typically mixed with use case in the Logical View of the system in the development. Sequence diagrams are calledevent diagrams orevent scenarios andtiming diagrams. A sequence diagram shows the parallel vertical lines (lifelines), the different processes or objects that live parallel and the horizontal arrow. The messages exchanged between them in an order in which they have occurred. This allows the specification of simple runtime in a graphical manner. Sequence diagrams Create the account Account Acceptance res Upload the file File received confirmation Create the End User account Account confirmation Request the file File request confirmation File sending response VMââ¬â¢s details Threshold Details Account details Figure 5.2 : Sequence diagrams Activity diagram Activity diagrams is a graphical representations of flow of work of steps that have taken in the activities and actions with support for choice and interact and concurrency. In the UML activity diagrams are intends to for both the computational and also for the organizational processes (i.e. workflows).. Activity diagrams 1 Figure 5.3 : Activity diagrams 1 Activity diagrams 2 Figure 5.4 : Activity diagrams 2 Functional modeling Afunction modelorfunctional modelinsystems engineeringandsoftware engineering is a structured representation of thefunctions(activities,actions,processes,operations) within the modeledsystemor subject area. A function model, similar with theactivity modelorprocess model, is a graphical representation of anenterprises function within a defined scope. The main purposes of the function model is to describe the functions and processes, and help with discovery of information needs and also help to identify opportunities, and establish a basis for determine the product and the actual service costs. Data flow diagram Adata flow diagram(DFD) is a graphical representation of the flow of data through aninformation system modeling its process. The step is used to create an overall view of the system which can be elaborated later. DFDs are also used for visualizationofdata processing(structured design). A DFD shows what type of information will be input to and what type of information will the output from the system, and from where the comes and from where it goes to, and where the data will be exactly stored in the system. It does not show information about the time of processes or gives the information about the processes will operate in parallel way or in a sequence way (which is shown on aflowchart). DFDs are the model of the proposed system. They should clearly show the requirements on which the new system should be built. Later during the design activity is taken as the basis for drawing the systemââ¬â¢s structure charts. The Basic Notation used to create a DFDââ¬â¢s are as follows: 1. Dataflow: Data move in a specific direction from an origin to a destination. 2. Process: People, procedures, or devices that use or produce (Transform) Data. The physical component is not identified. 3. Source: External sources or destination of data, which may be People, programs, organizations or other entities 4. Data Store: Here data are stored or referenced by a process in the System. ER Diagram An ER model is an abstract way of describing adatabase. In the case of arelational database, which stores data in tables, some of the data in these tables point to data in other tables. It is essential to have one of these if you want to create a good database design. The patterns help focus on how the database actual works with all of the interactions and data flows. Building Blocks of Entity Diagram are: Entities: An entity is a ââ¬Ëââ¬â¢thingâ⬠that exists and can be uniquely identià ¯Ã ¬Ã ed. Relations: A (binary) relationship type is an association between two entity types. Attributes: Attribute names (or simply attributes) are properties of entity types. The Main Advantages of Entity relation diagrams are: They are relatively simple They are user friendly They can provide a unique view of data, which is independent of any data models Module Description NICE Systems consists of following sub modules such as: Data Owner Cloud Service Provider (CSP) Virtual Machine for Cloud data storage Attack Analyzer Remote User Data Owner: Users who have the data and that have to be stored in the cloud and rely on the cloud for data computation, it consist of both the individual consumers and the organizations. Cloud Service Provider (CSP): A Cloud Service Provider (CSP) who has significant resources and who are expert in building and managing distributed cloud storage servers on different virtual machines, owns and operates live Cloud Computing systems. Virtual Machine for Cloud data storage Cloud data storage, a user will stores his data through a Cloud Service Provider (CSP) into a group of cloud servers, which are running in a simultaneous, the user interacts with the cloud servers via CSP to access or retrieve his data. In some cases, the user may need to perform block level operations on his data. Users should be equipped with security means so that they can make continuous correctness assurance of their stored data even without the existence of local copies. The cloud consists of different Virtual machines on which the owner data will be allocated and shared and the cloud will listen the different types of attackers called Stable. There does not exist any known vulnerability on the VM. Vulnerable. Presence of one or more vulnerabilities on a VM, which remains unexploited.
