Doonesbury Conclusion
Doonesbury Conclusion Ive received this link multiple times today (thanks Kevin and Susan), so I might as well post it before I go see Fanaa From this weeks Doonesbury FAQ: The previous Straw Poll invited readers to choose among three academic futures for Alex Doonesbury: Should she go to Rennselaer, Cornell, or MIT? Voting was brisk. Wait, let us rephrase that: Voting was insane, rampant, ingenious, and impressively ruthless. An MIT student put up Doonesbury Voting Hack, a web site (adorned with art borrowed from the Town Hall) which enabled would-be-ballot-stuffers to spew out over a million votes in a single night. Were all running cgi hack scripts lold one MIT blogger, Ive voted 3 or 4 thousand times! Fortunately the prophylactic measures swiftly implemented by the DTHs crack tech crew kept most of the votes from making it into the poll. The idea of outing the main culprit was briefly considered (a 58, 115-lb. freshman from New York its amazing what you can find out about a person online), but as he left a clear trail and probably didnt expect the hack to be as successful as it was, it seemed enough to deny the MIT network access to our servers. Besides, we had to take his thoughtfulness into account: Please, he cautioned on the updated version of his hack site, only keep one instance of the program running at a time so we dont kill the server again. Meanwhile Rennselaer had also stepped up to the plate or rather made their own attempt to move it. As campus blog entries indicate, token reservations were overcome (It would be entirely unethical of me to stuff a ballot box, or suggest any others use the same, with command lines such as) and a curl was disseminated, intended to accomplish pretty what the MIT script had done using Flash. The Rensselaer effort was less successful still, several hundred thousand votes bounced off our servers. By the time a handful of indy hackers made their run at the Straw Poll, the ballot box was adequately unstuffable. Cornell blogage shows that students there were watching the fray (Me thinks the site is being bombarded by a script war between Troy and Cambridge), but a higher, or more urgent, course was taken. (Were at a disadvantage, because weve got finals now and presumably no one has the free time to write a Cornell spamming script.) The Cornell alumni office had early-on taken an above-board interest, alerting alums to the situation and urging them to vote, but this effort did not bring Cornellians to the poll in numbers sufficient for Big Red to catch up. Were obviously not trying hard enough to cheat, lamented a dismayed blogger. However, students and alums managed to post many passionate, articulate, humorous, and convincing posts on our Blowback page, all making the case that Alex should head to Ithaca. In acknowledgement of this impressive and moving effort, the Doonesbury Town Hall is pleased to award Cornell the Doonesbury Straw Poll Congeniality Award. As for the question at hand Where will Alex go to school? the will, chutzpah, and bodacious craft of the voting public will be respected. A careful check of the applicable rulebook indicates that queering the results was not specifically prohibited. And by tradition, engineers, hackers and techfolk will assume that in a problem-solving situation of this nature, there is no box out of which they are not expected to climb. The Doonesbury Town Hall thanks all those who took the time and trouble to vote, even those who voted only once. Ms. Doonesbury will be attending MIT. According to a story at Editor Publisher, More than 175,000 votes legitimate or otherwise had come in when the poll was removed from Doonesbury.com Tuesday morning. Final percentages were not posted on the site today. But when contacted by EP this morning, a Doonesbury Town Hall spokesman said MIT had 48%, Rensselaer 32%, and Cornell 19%. Off to the movies I go

History of American Economic Growth in the 20th Century
As the American economy matured in the 20th century, the freewheeling business mogul lost luster as an American ideal. The crucial change came with the emergence of the corporation, which appeared first in the railroad industry. Other industries soon followed. Business barons were being replaced by technocrats, high-salaried managers who became the heads of corporations. By the start of the 20th century, the era of the industrialist and the robber baron was coming to a close. It was not so much that these influential and wealthy entrepreneurs (who generally personally owned majority and controlling stakes in their industry) disappeared, but rather that they were replaced with corporations.à The rise of the corporation triggered, in turn, the rise of an organized labor movement that served as a countervailing force to the power and influence of business. The Changing Face of the Early American Corporation The largest early 20th-century corporations were much larger and more complicated than the commercial enterprises that came before. To maintain profitability in a changing economic climate, American companies in industries as diverse as oil refining to whiskey distilling began to emerge in the late 19th century. These new corporations, or trusts, were exploiting a strategy known as horizontal combination, which granted those corporations the ability to limit production in order to raise prices and maintain profitability. But these corporations regularly ran into legal trouble as violations of the Sherman Antitrust Act. Some companies took another route, employing a strategy of vertical integration. Instead of maintaining prices through control of the production supply as in horizontal strategies, vertical strategies relied on obtaining control in all aspects of the supply chain required to produce their product, which gave these corporations more control over their costs. With more control over costs came more stable and protected profitability for the corporation. With the development of these more complicated corporations came the need for new management strategies. Though the highly centralized management of previous eras did not entirely disappear, these new organizations gave rise to more decentralized decision-making through divisions. While still overseen by central leadership, divisional corporate executives would eventually be given more responsibility for business decisions and leadership in their own piece of the corporation. By the 1950s, this multi-divisional organizational structure became the growing norm for large corporations, which generally moved corporations away from reliance on high-profile executives and solidified the fall of the business barons of the past.à à The Technological Revolution of the 1980s and 1990s The technological revolution of the 1980s and 1990s,à however, brought a new entrepreneurial culture that echoed the age of tycoons. For instance, Bill Gates, the head of Microsoft, built an immense fortune developing and selling computer software. Gates carved out an empire so profitable that by the late 1990s, his company was taken into court and accused of intimidating rivals and creating a monopoly by the U.S. Justice Departments antitrust division. But Gates also established a charitable foundation that quickly became the largest of its kind. Most American business leaders of today do not lead the high-profile life of Gates. They differ greatly from the tycoons of the past. While they direct the fate of corporations, they also serve on boards of charities and schools. They are concerned about the state of the national economy and Americas relationship with other nations, and they are likely to fly to Washington to confer with government officials. While they undoubtedly influe nce the government, they do not control it ââ¬â as some tycoons in the Gilded Age believed they did.

Autism Is Classified As A Developmental Disorder - 1281 Words
According to Simmons et al. (2009), autism is classified as a developmental disorder characterized by difficulties with social interaction, social communication, and an unusually restricted range of behaviors and interests. Along with behavioral and social impairments, a diagnosis of autism also requires a clinically significant delay in language development before the age of three. Asperger Syndrome has similar signs and symptoms to autism without the language delay. Together with Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS), these disorders form the category of Autism Spectrum Disorders (Simmons et al., 2009). Because the signs and symptoms of ASDs are almost entirely behavioral, a variety of tests, interviews, and direct or indirect observations are used in different combinations based on age and/or language level to receive the most reliable diagnosis. Although there is controversy regarding the increased prevalence of ASDs, it is obvious that there is highe r regard for understanding the nature of these disorders, causing an increase of research related to this field of study. It is to be noted, however, that there are a handful of general issues to be addressed when running experiments with afflicted individuals.

Right to Information Act in Indian Democracy Free Essays
In modern constitutional democracies, it is axiomatic that citizens have a right to know about the affairs of the Government which, having been elected by them, seeks to formulate sound policies of governance aimed at their welfare. The ideals of modern democracy are built up on the principle that freedom of speech and expression is necessary, for self expression which is an important means of free conscience and self fulfillment. It enables people to contribute to debates of social and moral issues. We will write a custom essay sample on Right to Information Act in Indian Democracy or any similar topic only for you Order Now It is the best way to find a truest model of anything, since it is only through it, that the widest possible range of ideas can circulate. It is the only vehicle of political discourse so essential to democracy and the largest democratic country, India, stands 55th in the list of 68 countries in the enactment of Right to Information. Inorder to promote transparency and accountability in administration, the Indian Parliament enacted the Freedom of Information Act, 2002, which was repealed later and a new act, the Right to Information Act( RTI) came into force on 12 October 2005. The new law empowers Indian citizens to seek information from a public authority, thus making the Government and its functionaries more accountable and responsible.As our former PM Atal Behari Vajpayee had said, â⬠The Government wants to share power with the humblest; it wants to empower the weakest. â⬠It is precisely because of this reason that the RTI has to be ensured for all. It is a matter of pride that we have given to ourselves a tool which has the potential to usher in transparency and reduce corruption . Information is indispen sable for the functioning of a true democracy. People have to be kept informed about current affairs and broad issues-political, financial, social and economic.Soli Sorabjee stressing on the need of RTI aim at bringing transparency in administration and public life, says, â⬠Lack of transparency was one of the main causes for all pervading corruption and RTI would lead to openness, accountability and integrity. â⬠More important than the issue of corruption, each and every one of us being the citizens of a democratic country like India are the unlabeled rulers of our country. We elect our representatives to do our part and so every citizen has the right to be informed of what happens in his country except some information that has confidential nature.RTI is critical for the existence of democracy. Only with the right information, we can work in the right way. With the information, people can fight corruption, they can expose corruption, they can check whether the governmental strategies are aiming the right way, they can engage in democracy. We just get informaton initially and after that we have to participate in governance. Until the implementation of RTI, democracy used to be from election to election that goes for five years. Now we can go out and say that we want to participate in the governance.It has been highlighted in various reports through many case studies that RTI has adequate ââ¬Å"teethâ⬠to bring in transparency and reduce corruption. But the case studies accept the fact that the Act has not yet reached the stage of implementation which was envisioned. The Government/Public Authority machinery was not found well-equipped to respond to the needs of the RTI. There is a serious failure in record management (where there is delay in processing and the PIOs not being aware of record management guidelines). There is also lack of training /knowledge and the usage of information technology is very less. Most of the PIOs have taken up the role unwillingly leading to low motivation among them. A separate study is recommended to improve the current record management systems and make them ââ¬Å"RTI friendlyâ⬠. Inorder to ensure good performance of PIOs in implementing the Right to Information Act, allocation of responsibility of PIOs and AAs to senior level officials in a Public Authority is required. Also,mass awareness campaigns may be conducted to increase public knowledge and awareness.This may also help to encourage citizen involvement and debates. Awareness could be created within the authority by putting displays. A conducive and facilitative environment at Government offices is a necessary condition to ensure that citizens are able to apply and receive information in a convenient manner. If all these flaws and inadequacies in the implementation of the law are rectified, the Act can definitely become a wonderful ââ¬Ëdemocratic toolââ¬â¢ which can help people well informed, be aware of the way our country is progressing, take part in democracy and have a transparent society.

Splice Sleeve Classroom and Shop Manuals
Question: Discuss about theSplice Sleevefor Classroom and Shop Manuals. Answer: Introduction The splice sleeve is a coupler used for compression pre-cast, tilt up and other similar connections. The splice sleeve connectors are very effective for column-to-footing and column-topier cap bridge assembly (Parks et al., 2016). The splice sleeve coupler has proved its durability against earthquakes over the years. Splice sleeve coupler is connected between the prefabricated concrete. It provides great construction tolerance and load transfer mechanism (Amelia et al., 2016). Research has demonstrated that splice sleeve couple provides durability and increases the displacement ductility of the structure. The report discussed the benefits and complexities associated with the coupler. The paper is based on research of literature and practical examples. Innovation of Splice Sleeve (why it is used in Civil Construction Projects) Splice sleeve was innovated in the late 1960s and has been in use in the civil engineering sector for over the past 40 years. The first innovation was done in the USA before it spread to japan and all over the world. Splice sleeve is used in civil engineering because of its high-performance properties. Due to this property, no fatalities have been reported related to the application of this device(Pickerill, 2017, p. 241). It is used I buildings to withstand the deformations and stresses resulting from earthquakes. Design of Splice Sleeve The design of s splice sleeve can best be demonstrated by taking the example of NMB splice sleeve. The NMB splice sleeve is one of a mechanical coupler used in the splicing of reinforcing bars that applies a sleeve which is cylindrical in shape. The cylindrically shaped steel is filled with cement on the basis of high early strength grout. From this step, the reinforcing bars which are to be spliced are entered into the sleeve. These reinforcing bars are inserted in such a way that they converge at almost the sleeve centre. SS Mortar is then used in filling the interior of the sleeve. It is also important to note that SS Mortar is the only grout acceptable grout as certified by SSNA as conforming to the requirements and standards to be used in splice sleeves under ICC-ESR 3433. There are two codes used as guides in the design of splice sleeves i.e. ACI 318-08(IBC-2006, UBC-970), Type 1 and 2. According to type 1, the specified mean rebar point should be a minimum of 125%. On the other hand, for the case of type 2, ACI31808 provides the guideline in the spacing of the bars for any specified tensile strength of the splice sleeve(Loo, 2009, p. 188). In this type, a specified minimum of 160% of the yield point of rebar can as well be adopted in line with ICBO UBC-97. Importantly, if the splice lies within a moderate to the high seismic region of a plastic hinge joint, then type 2 must be specified. On one end of the precast element, sleeves are embedded at the precast plant. The principal reinforcing bars are inserted midway into the sleeves and the bars are made to protrude from the other end of the precast element. During the construction stage, the precast members that were precast at the precasting plant are joined. This is done through the insertion of protruding bars from the end of the precast element into the sleeves of the adjacent member. This is followed by grouting of the sleeves thereby creating a continuity of the reinforcing bars throughout the connection. This process is called emulation and the splice sleeve made through this process is known to be an emulative connection for precast systems. Strength of Splice Sleeve Splice sleeves have both compressive and tensional strengths which are above the minimum provisions by ASTM A706 and A615. The strength is achieved through embedding the sleeve bars to one end of the precast elements after the precast(Pickerill, 2017, p. 216). The material components are partly a reason for the consistency excellent performance including steel. Durability of Splice Sleeve Due to their high strength and ability to withstand both compressive and tensile forces, splice sleeves are very durable and can be used for a long duration. By embedding sleeve bars into precast elements, a stronger and more durable structure is formed. Splice sleeves have been made even more durable by fabrication and design of mechanical splices. These splices are made by modifying the conventional steel pipes with steel spiral reinforcement, bolts, steel bars which are straight and tapered shapes which improve the strength of the bond and the confinement pressure. Still, some sleeve spices are made of hollow sections square in shape, aluminium tubes besides polymer reinforced with fibre instead of the cylindrical steel pipe initially used in the splice region. These modifications aid in the elimination of the spread of splitting cracks in the grout (mechanical locking material) around bars of steel. All these end up in increasing the overall strength of splice sleeves and hence the durability. Uses of Splice Sleeve Due to their high performance in the provision of solid support for the structure, splice sleeves find their applications in: Retaining walls Concrete Barge Sound Barrier walls Concrete box culvert; and Caisson In all these above applications, the strength and durability form the basis of the preference of sleeve splice (Amelia et al., 2016). Merits and Demerits of Splice Sleeve Merits Include: High compressive and tensile strength: Slip sleeves take advantage of the mechanical gripping of the reinforcing bars and the slip-bond resistance of the grout to achieve maximum tensile strength. In such a setup, the grout serves to be the medium of transfer of load as well as the bonding material between sleeves and bars. High durability: as a result of the high tensile and compressive strengths and the nature of the materials used in the design of splice sleeves their durability is highly enhanced. High stiffness of the components: Steel, hollow square sections and aluminum tubes and Portland cement which are the main materials used in the design of slip sleeves are very stiff hence able to withstand external forces which would otherwise lead to breakage and therefore failure of the system. Saves time as it is quick to assemble: The design of slip sleeves involves not only a few components but also simple components. The simplicity of the components extends to the simplicity with which the assemblage is done. It basically involves inserting the reinforcing bars into sleeves and protruding it from the other end of the already precast elements. The bars are joined adjacent to each other and then reinforced for continuity. High performance: for over the 40 years since slip sleeves were first deployed in the construction, there have not been any reported serious cases of failure of systems built on them. Instead, excellent and high-quality performances have been recorded thereby the reason for the continued increase in the popularity and use of the material. Disadvantages Costly construct splice sleeves: The construction of splice sleeves involve two stages which occur at different places i.e. precasting of elements done at the precasting plant and the actual design and assemblage of the sleeves which is done at the construction stage/industry. Can easily shrink under bad environmental conditions hence proper storage against environmental hazards is required. The sleeves must be kept away from extra heat to maintain its usefulness. This makes it quite challenging to be used in regions with hot and dry climates. Requires proper management of slack to avoid any future connectors damage. An omission of such care would lead to considerable design failures. References Parks, J., Papulak, T., Pantelides, C. (2016).
