Why Google s Digital Library Project Is A Violation Of...

A co-operation about digitizing the books in libraries was announced by Google and several major libraries on December 14, 2004. In this project, all the books in these libraries will be sent to Google for scanning and making digital copies, then they will entered into the Google search engine. At last, all the library books will be returned to libraries unharmed. Allowing all Google’ s users search the full text the these books by using Google search engine, which is the purpose of this project, can huge increase the assessment to the works open to public (Hanratty, 2004:1). This article will analyze why Google’ s Digital Library Project is a violation of international copyright law and discuss the practical implications for legislature†¦show more content†¦These rules require rigidly the users of fair use can not unjustly earn money by using these works, then the nature of the copyrighted work that can not do harm to the copyrightholder, at the same time the use which can decrease the value of the works in future market is also prohibited (Prasad and Agarwala, 2008:253).

First of all, Google is a ‘for-profit’ company, Prasad and Agarwala argued that although Google can not received money from books directly, it still can make profit by the advertising space which Google sell on its digital library web page (2008:258). Moreover, Google can improve its value of service by this project, which increase the value and the reputation of Google, which is might not intentional.

Why Overpopulation Is A Major Issue - 1653 Words

Everyone knows that overpopulation is a major issue; an issue is only going to increase over the next few decades. Every person should have a general understanding of this problem because it is going to affect everyone on the planet if it has not done so already. Many countries on our planet now are already overpopulated. In many third world countries, parents do not have enough money to feed themselves, let alone food for their own children. It is estimated that over one billion people wake up every day and do not have enough food or safe drinking water. In addition, according to many scientists, we are supposed to exceed 14 billion people by 2100 and nine billion by the year 2048. Even though we will most likely all be passed on, imagine a world with seven billion more people. How will people be able to have jobs and support their families? What is our world’s carrying capacity? Before we can try to answer that, we need to understand what carrying capacity is, according to the Merriam-Webster: Dictionary it is the maximum number of individuals of a species that can exist in a habitat indefinitely without threatening other species in that habitat (â€Å"Carrying Capacity†). Some might try to say that technically, by that definition we have already reached out carrying capacity in some parts of the world. We might not truly know the carrying capacity of the Earth is until we reach that limit. That is a scary question to think about, but hopefully by then we will have found otherShow MoreRelatedOverpopulation Is An Issue Of Overpopulation930 Words   |  4 PagesOverpopulation is an issue that many in the world may never face, however, the ones that do experience this issue know the struggles that it can pose to the overall quality of life.

Pinnacle Foods Ipo Free Essays

Pinnacle Foods Inc. : Initial Public Offering MACKK Consulting Group BSAD 444. 20 April 1st, 2013 Company History Pinnacle Foods Group is a food packaging company specializing in shelf stable and frozen food categories. We will write a custom essay sample on Pinnacle Foods Ipo or any similar topic only for you Order Now The company was formed in 1998 as Vlasic Foods International, acquiring several food-manufacturing brands such as Swanson TV dinners and Open Pit from the Campbell Soup Company. Pinnacle’s portfolio of iconic brands dates back in existence to the 1800s. The earliest brand owned by Pinnacle Foods, Armour Star, has existed since 1867 when Philip Armour founded it as Armour and Company. Armour was the first company to produce canned meat and was once Chicago’s most important business, helping to make the city and its stockyards the center of the American meatpacking industry. Throughout the late 1800s and 1900s, iconic brands such as Duncan Hines, Log Cabin, Aunt Jemima and Hungry Man were introduced and now are a part of the Pinnacle Foods name. Pinnacle Foods acquired Aurora Foods in 2003 when the company’s health was in jeopardy due to lawsuits in 2001. Ian Wilson, a former executive with Coco-Cola, founded Aurora Foods in 1995 using the company to purchase Van de Kamp Seafood from Pillsbury along with several other brands. As a result of major lawsuits in 2001, Wilson and other Aurora executives plead guilty to securities fraud for misrepresentation of the company’s financial statements. Jim Smith replaced Wilson as CEO of Aurora Foods until 2002, at which time motions were set in place that lead to Pinnacle’s acquisition of Aurora. Pinnacle closed Aurora’s Missouri offices and moved them to Cherry Hill, New Jersey where the currently remain. In 2007 The Blackstone Group, a New York City private equity firm, bought Pinnacle Foods for $2. 16 billion (G. S. , 2007). Since then, Pinnacle Foods has acquired Birds Eye Foods, Inc. , adding a mix of frozen and specialty brands to its already iconic portfolio. Industry Overview * Ashley Company Overview Today Fortune Magazine ranks Pinnacle in the Top 1,000 Companies with over 4,000 employees. Pinnacle’s products can be found in more than 85% of American households and are leaders in their respective categories, holding the first or second market share position in 10 of the 12 of the categories in which they compete. Pinnacle currently focuses on growing their â€Å"leadership brands† while reinvigorating their â€Å"foundation brands†. Their leadership brands are those with the most potential for growth and innovation. These include brands such as Vlasic, Duncan Hines, and Ms. Butter-Worth’s. Pinnacle prides themselves on debuting category breakthroughs with these brands. These leading brands are used prominently in marketing campaigns that celebrate their robust vitality. Pinnacle’s foundation brands are those that have a strong and recognizable reputation in most households. Families already know and love these brands such as Aunt Jemima Frozen Breakfast, Open Pit, and Hungry-Man. Pinnacle strives to raise the bar with these familiar foods through new flavours and health benefits. Pinnacle must be innovative with these familiar brands to ensure they remain as popular as they currently are. Financial Overview Financially, Pinnacle has experienced minimal growth over the last year. Net sales increased marginally from $2. 47 billion in 2011 to $2. 48 billion in 2012 and in North America specifically, net sales grew a meager 1% from $2. 07 to $2. 08 billion. EBIT was $284 million in 2012, after giving effect to $66 million in pre-tax charges related to restructuring and refinancing. This restructuring also impacted net earnings, as Pinnacle had to pay $51 million in after-tax charges and was left with $53 million in net earnings. Despite these charges, this net income shows a strong recovery from 2011 when the company suffered a net loss of $47 million. Total capital expenditures were $78 million in 2012, down from $117 million in 2011. These expenditures include footprint consolidation. A summary of these figures can be seen below in Exhibit 1. Exhibit 1: Pinnacle Financial Statements It can be seen in Exhibit 1 that Pinnacle has a substantial amount of acquisition, merger and other restructuring charges. These charges are primarily related to Pinnacle closing facilities in Washington, New York, Wisconsin, and Delaware. A complete breakdown of these expenditures has been included in exhibit 2. Exhibit 2: Acquisition, merger, and other restructuring charges One of the problems that Pinnacle currently faces is their large amount of debt. They have roughly $550 million of a term loan that is due in 2014. This resulted in Pinnacle entering the market with a $300 million incremental term loan last year, dubbed F, with proceeds to be used to help repay the $550 million. Pinnacle has an additional $400 million E term loan that was syndicated earlier in 2012. This loan matures in October 2018 and is covered by a 101 soft call premium until April 17, 2013. Proceeds from that deal were used to issue $199 million in 10. 625% subordinated notes due in 2017. Altogether Pinnacle has about $641 million outstanding under the extended term loan due in 2016 (Bisbey, 2012). This is one of the primary reasons for Pinnacle’s IPO, as will be discussed later in the report. The balance sheet below summarizes Pinnacle’s debt obligations as well as their assets and equity. Exhibit 3: Pinnacle’s Balance Sheet for 2011 and 2012 After performing a two-finger analysis of this balance sheet it can be concluded that Pinnacle has not made any drastic changes over the past two years. Assets have decreased slightly but that was coupled with a decrease in liabilities by roughly the same amount which is reasonable. Exhibit 4 is a portion of Pinnacle’s cash flow statement that helps explain these changes in the balance sheet. Pinnacle’s cash flows from financing increased 212% between 2011 and 2012, the vast majority of this expenditure being the repayment of debt. By making a number of loan repayments, Pinnacle decreased their cash and therefore their assets, while also reducing their liabilities. Exhibit 4: Cash Flows from Financing Activities Ratio| 2012| 2011| Return on Equity| 5. 9%| -5. 54%| Return on Assets| 1. 19%| -1. 05%| Return on Sales| 11. 46%| 7. 4%| Current Ratio| 2. 11| 2. 17| Quick Ratio| 1. 04| 1. 17| Debt-to-Equity Ratio| 3. 95| 4. 26| | | | Exhibit 5: 2012 Ratio Analysis of Pinnacle Group Inc. These ratios †¦ IPO The food-industry sector is changing due to increased globalization, vertical integration, and mergers and acquisitions. This is forcing many firms to look to alternatives to debt financing in order to keep up with the competition. The public equity market is a valuable option in financing the growth necessary to survive amongst competitors, as it offers access to more equity capital than could be attained from other sources (Stegelin Houston, 2007). With millions of dollars in debt obligations coming up due in the next few years, it is understandable that Pinnacle is having an Initial Public Offering to raise capital. This follows suit with research that has shown that as a food-industry firm’s leverage ratio increases, the likelihood of an IPO increases as well (Stegelin Houston, 2007). It has also been noted that the probability of a food-industry firm IPO decreases with the firm’s size and age (Stegelin Houston, 2007). Pinnacle is currently 15 years old which is incredibly â€Å"young† compared to industry leaders Kraft and Kellogg which are both over 100 years old. This could be a contributing factor to why they are wanting to go public. This IPO will follow 13 other offerings in 2013 backed by financial sponsors such as private-equity firms. These 13 other offerings can be used to loosely predict the success of Pinnacle’s IPO, as Pinnacle is backed by private-equity firm Blackstone. These IPOs were successful, seeing an average first-day gain of 22% and are up an average of 21% from their listing dates. These results are promising in comparison to 30 other IPOs at large, showing an average 15% first-day gain and a gain of 19% from the listing dates (Driscoll, M. 2013). Another important benchmark is the IPOs of other food sellers. There were mixed results regarding the success of food seller IPOs in 2012. The health food sector showed strength with natural food companies Annie’s Inc. , Natural Grocers by Vitamin Cottage Inc. , and WhiteWave Foods Co. performing well since their IPOs. Annie’s shares have more than doubled s ince being listed last March while the value of Natural Grocers has risen over 40% since their listing in July (Driscoll, M. , 2013). On the other hand, Roundy’s Inc. and Amira Nature Foods Ltd. have underperformed since their IPOs. Roundy’s is a Midwestern supermarket chain and Amira is a rice seller, both of which are down about 20% from their offerings in October and February respectively (Driscoll, M. , 2013). Since Pinnacle offers processed, packaged foods, benchmarking their success from the natural, organic food IPOs is not very reliable. With people becoming more and more health conscious these days, it is not surprising that these health food companies found success in their IPOs. Although Pinnacle does carry the frozen vegetable brand Birdseye, they also carry a number of brands that would not be classified as healthy. Of the aforementioned companies, the most reliable comparison for Pinnacle would likely be with Roundy’s, the supermarket chain. Supermarkets sell a wide variety of processed and pre-packaged foods, and are the medium through which Pinnacle’s brands are sold. However, there is still not a strong correlation between the two firms. On March 27th, 2013, Pinnacle announced their Initial Public Offering of 29,000,000 shares of common stock at $20 per share. Pinnacle also granted the underwriters a 30-day option to purchase an additional 4,350,000 shares at the IPO price. It is estimated that Pinnacle will raise net proceeds of about $545. 2 million after subtracting underwriting costs. Pinnacle plans to use the entirety of these earnings to pay off some of their debt. They plan to redeem $465 million in aggregate principal amount of 9. 25% Senior Notes due in 2015 at a redemption price of 100%. The remainder of their IPO proceeds, along with some cash on hand, will be used to repay $119 million of the senior secured term loan B facility maturing in April 2014. IPO Success Pinnacle Foods had a very successful IPO on March 28, 2013. The company issued a total of 33,350,000 shares of common stock, including the entirety of the additional 4,350,000 shares that the underwriters had the option to purchase. Pinnacle now has a total of 117. 2 million common shares outstanding. Net of all underwriting discounts, Pinnacle raised $627 million through this offering, which is $81. 8 million more than they had initially anticipated. Pinnacle will couple this money with $40 million of cash on hand to pay down $667 million in outstanding debt. Instead of their initial plans of repaying $119 million of their term loan B due next April, they will repay $202 million. Exhibit 6: Pinnacle Foods’ Stock Performance Since IPO as Compared to SP 500 As can be seen in Exhibit 6, Pinnacle shares (blue line) seem to be experiencing steady growth since their IPO on March 28, 2013. This is especially positive since the SP 500 (brown line) seems to be doing quite the opposite. Pinnacle shares have increased from their low of $22. 15 to a high of $24. 61, an 11% increase.

Submit this completed document by the assignment due date found in the Syllabus. Please make sure that your answers are typed in RED. Respiratory Volumes Activity 2: Measuring Normal Respiratory Volumes 1. Minute respiratory volume: 7,500 ml 2. Judging from the trace you generated, inspiration took place over how many seconds? 2 seconds 3. Expiration took place over how many seconds? seconds 4. Does the duration of inspiration or expiration vary during ERV or FVC? Yes Activity 3: Effect of Restricted Air Flow on Respiratory Volumes 1. How does this set of data compare to the data you recorded for Activity 2? The MRV is 3075 and the breathing is not as strong. 2. Is the respiratory system functioning better or worse than it did in the previous activity? It is worse. Explain why. The breathing is more shallow and incomplete. The lungs are not able to inhale or exhale as much as in Activity 2 3. What is the effect of reducing the radius of the air flow tube on respiratory volumes? We will write a custom essay on Respiratory System Mechanics Worksheet specifically for you for only $16.38 $13.9/page Order now The air flow was decreasing, which decreased the respiratory volume. 4. What does the air flow tube simulate in the human body? The trachea 5. What could be some possible causes of reduction in air flow to the lungs? An allergic reaction could cause the trachea to swell which would restrict air flow or an obstruction could block some or the entire trachea causing the air flow to decrease as well. Factors Affecting Respiration Activity 4: Effect of Surfactant on Respiratory Volumes 1. When surfactant is added, what happens to the tidal volume? It increases the amount of air being inhaled 2. As a result of the tidal volume change, what happens to the flow into each lung and total air flow? The air flow increases into the lungs and the total air flow increases 3. Why does this happen? Surfactant allows the wet surface of the alveoli to expand and not stick together. Activity 5: Effect of Thoracic Cavity Puncture 1. What happened to the left lung when you clicked on the valve button? It collapsed and lost the ability to fill with air 2. Why? Because it is no longer has one way in and one way out. The opened valve does not allow air to enter and stay in the lung to become oxygenated. . What has happened to the â€Å"Total Flow† rate? It decreased 4. What is the pressure in the left lung? 0 5. Has the pressure in the right lung been affected? No 6. If there was nothing separating the left lung from the right lung, what would have happened when you opened the valve for the left lung? It would also collapse Why? There would be nothing separating them so they would act a s one lung. If the valve opened, it would have the same affect on both as what happened to the left lung when the valve was opened. 7. Now click the valve for the left lung again, closing it. What happens? It stays collapsed. Why? The lungs valve was only closed, but the lung itself was not repaired. 8. Describe the relationship required between intrathoracic pressure and atmospheric pressure in order to draw air into the lungs. The intrathoracic pressure has to be the opposite of the atmospheric pressure in order to cause the air to be pulled into the lungs. 9. Design your own experiment for testing the effect of opening the valve of the right lung. Was there any difference from the effect of opening the valve of the left lung? No Variations in Breathing Activity 6: Rapid Breathing . What happens to the PCO2 level during rapid breathing? It decreased 2. Why? The breathing became quick and very shallow so the amount of oxygen being inhaled was less. Activity 7: Rebreathing 1. What happens to the PCO2 level during rebreathing? 2. Why? The breathing became deeper and more oxygen was inhaled with each breath. 3. Did the total flow change? Yes it increased 4. Why? More oxygen was being tak en in with each breath 5. How does the rebreathing trace compare to your baseline trace? The inhales and exhales become deeper and the get deeper with each breath 6. Why? .ue48f3e068d9b21ffb7e334a28c91ba45 , .ue48f3e068d9b21ffb7e334a28c91ba45 .postImageUrl , .ue48f3e068d9b21ffb7e334a28c91ba45 .centered-text-area { min-height: 80px; position: relative; } .ue48f3e068d9b21ffb7e334a28c91ba45 , .ue48f3e068d9b21ffb7e334a28c91ba45:hover , .ue48f3e068d9b21ffb7e334a28c91ba45:visited , .ue48f3e068d9b21ffb7e334a28c91ba45:active { border:0!important; } .ue48f3e068d9b21ffb7e334a28c91ba45 .clearfix:after { content: ""; display: table; clear: both; } .ue48f3e068d9b21ffb7e334a28c91ba45 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ue48f3e068d9b21ffb7e334a28c91ba45:active , .ue48f3e068d9b21ffb7e334a28c91ba45:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ue48f3e068d9b21ffb7e334a28c91ba45 .centered-text-area { width: 100%; position: relative ; } .ue48f3e068d9b21ffb7e334a28c91ba45 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ue48f3e068d9b21ffb7e334a28c91ba45 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ue48f3e068d9b21ffb7e334a28c91ba45 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ue48f3e068d9b21ffb7e334a28c91ba45:hover .ctaButton { background-color: #34495E!important; } .ue48f3e068d9b21ffb7e334a28c91ba45 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ue48f3e068d9b21ffb7e334a28c91ba45 .ue48f3e068d9b21ffb7e334a28c91ba45-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ue48f3e068d9b21ffb7e334a28c91ba45:after { content: ""; display: block; clear: both; } READ: Henrik Ibsen Essay ThesisRebreathing happens to try and reoxygenate the body to a normal level and to bring the heart beat back to a normal level. Activity 8: Breath Holding 1. What happens to the PCO2 level during breath holding? It increases 2. Why? All the oxygen from the breath is being held in and nothing is being expelled. 3. What change was seen when you returned to â€Å"Normal Breathing†? The breathing resembled rebreathing and the PCO2 level increased even more. Activity 9: Comparative Spirometry Normal Breathing: What do you think is the clinical importance of the FVC and FEV1 values? It measures the strength and health of the lungs 1. Why do you think the ratio of these two values is important to the clinician when diagnosing respiratory diseases? To see if a person is equal in the FVC and FEV1, depending on this could give a better insight on determining the problem. Emphysema Breathing: 2. Is the FVC reduced or increased? Decreased 3. Is the FEV1 reduced or increased? Decreased 4. Which of these two changed more? FEV1 5. Explain the physiological reasons for the lung volumes and capacities that changed in the spirogram for this condition. The amount of air being pulled into the lungs was decreased and the amount of air the lungs could hold was decreased. Acute Asthma Attack Breathing: 6. Is the FVC reduced or increased? Increased 7. Is the FEV1 reduced or increased? Decreased 8. Which of these two changed more? FVC 9. Explain the physiological reasons for the lung volumes and capacities that changed in the spirogram for this condition. The air flow is being blocked so the volume of air going into the lungs is a lot less. 10. How is this condition similar to having emphysema? Both conditions restrict the airway. How is it different? In asthma, the windpipes gets blocked my mucus, in emphysema, the alveoli in the lungs get clogged by mucus. 11. Emphysema and asthma are called obstructive lung diseases as they limit expiratory flow and volume. How would a spirogram look for someone with a restrictive lung disease, such as pulmonary fibrosis? It would look similar as the volume of the lungs would decrease but the breaths would not be quick, only shallow. 12. What volumes and capacities would change in this case, and would these values be increased or decreased? FVC,FEV,TLC, IRV would decrease, IRV increase 13. In an acute asthma attack, the compliance of the lung is decreased, not increased as it was for emphysema, and air flows freely through the bronchioles. Therefore, will the FEV1/FVC percentage be less than normal, equal to normal, or higher than normal? Less than normal Acute Asthma Attack Breathing with Inhaler Medication Applied: 14. Has the FVC reduced or increased? Is it â€Å"normal? Increased 15. Has the FEV1 reduced or increased? Is it â€Å"normal†? Increased 16. Which of these two changed more? FEV1 17. Explain the physiological reasons for the lung volumes and capacities that changed in the spirogram with the application of the medication. The medication allows the airways to open up more so that more oxygen can enter the lungs and the amount of oxygen the lungs can hold also increases.
