Learn More About Inventer Thomas Elkins

Dr. Thomas Elkins, an African-American inventor, was a pharmacist and respected member of the Albany community. An abolitionist, Elkins was the secretary of the Vigilance Committee. As the 1830s drew to a close and the decade of the 1840s began, committees of citizens were formed all across the north with the intention of protecting fugitive slaves from re-enslavement. As slave catchers sought fugitives vigilance committees provided legal assistance, food, clothing, money, sometimes employment, temporary shelter and assisted fugitives in making their way toward freedom. Albany had a vigilance committee in the early 1840s and into the 1850s. Thomas Elkins - Patents and Inventions An improved  refrigerator  design was patented by Elkins on November 4, 1879. He designed the device to help people have a way of preserving perishable foods. At that time, the common way of keeping food cold was to place items in a large container and surround them with large blocks of ice. Unfortunately, the ice generally melted very quickly and the food soon perished. One unusual fact about Elkins refrigerator was that it was also designed to chill human corpses. An improved chamber commode (toilet) was patented by Elkins on January 9, 1872. Elkins commode was a combination bureau, mirror, book-rack, washstand, table, easy chair, and chamber stool. It was a very unusual piece of furniture. On February 22, 1870, Elkins invented a combined dining, ironing table, and quilting frame. The Refrigerator Elkins patent was for an insulated cabinet into which ice is placed to cool the interior. As such, it was a refrigerator only in the old sense of the term, which included non-mechanical coolers. Elkins acknowledged in his patent that, I am aware that chilling substances enclosed within a porous box or jar  by wetting its outer surface is an old and well-known process.   Unique Folding Table A patent was also issued to Elkins on February 22, 1870, for a Dining, Ironing Table and Quilting Frame Combined (No. 100,020). The table seems to be little more than a folding table. The Commode The Minoans of Crete are said to have invented a flush toilet thousands of years ago; however, there is probably no direct ancestral relationship between it and the modern one that evolved primarily in England starting in the late 16th century, when Sir John Harrington devised a flushing device for his godmother Queen Elizabeth. In 1775, Alexander Cummings patented a toilet in which some water remained after each flush, thereby suppressing odors from below. The water closet continued to evolve, and in 1885, Thomas Twyford provided us with a single-piece ceramic toilet similar to the one we know today. In 1872, a U.S. patent was issued to Elkins for a new article of chamber furniture which he designated a Chamber Commode (Patent No. 122,518). It provided a combination of a bureau, mirror, book-rack, washstand, table, easy chair, and earth-closet or chamber-stool, which might otherwise be constructed as several separate articles.

Corporate Governance and Firm Value-Free-Samples for Students

Question: Prepare a report to be submitted to the AICD evaluating the evidence that the responsibility of a Company director is to place Shareholder Interests above those of other Stakeholders. Answer: Introduction Corporate governance is a type of organization or working place that deals with the functioning of the various stakeholders with an aim of earning maximum profit. There is board of directors that run or govern the organization. Any problem occurs to the organization is undertaken by the board of directors in order to solve the issue. A board of directors includes group of those representatives who looks after the behavior and the performances of the stakeholders in the organization. These representatives appointed by the shareholders of the other company that are board members of the organization. Stakeholder is a party who can be a shareholder, debtor, creditor, an investor, customers, and employees, one who does business with interest. Whole business or companys performance depends on the activity of stakeholders. on the others side, shareholders are the ones who put money into the business thereby creating more capital leading to more profit , due to which they share the amount of companys profit afterwards, play a dominating role. The report deals with the discussion on the functions of stakeholders and shareholder of the organization. By providing various features about the other stakeholders with compare to shareholders, it gives a proper reason to place the interest of the shareholder above those other stakeholders. As the Australia institute of company directors is concerned with the opinion to place the interest of shareholder above that of other stakeholders. Stakeholders Meaning Stakeholder is a party who can be a shareholder, debtor, creditor, an investor, customers, and employees, one who does business with interest. Whole business or companys performance depends on the activity of stakeholders. The decision of business is largely depends on the activities of stakeholders (Arjoon 2017). Stockholders are important because they create profit to the business or organization. Nature of stakeholder Stakeholders can be positive or negative depending on the organization work culture and environment. If the stakeholder gets success and satisfaction from the work then it is a positive stakeholder. Negative stakeholder means if an individual is unsatisfied, does not get enough success from the work and the organization. The organization is unable to fulfill the requirements of stakeholders therefore creates negative impacts on stakeholders (Boddewyn and Buckley 2017). Due to negative impacts, stakeholders might not help in the work of the organization, will not follow lean manufacturing practices. Stakeholders when acts as investors, then they deal with decision making, policies and plans of an organization to run smoothly. They also check the financial stability of the organization if the stakeholders are the committed investors. Stakeholders can be internal as well as external. Internal stakeholders are the customers, employees. For instance, if the employees do not get proper facilities or good salaries in return of their efficient and hard work, they are bound to act as negative stakeholder for those organizations and they will not be motivated anymore to help that organization in generating profit. Other way round, if the employees get good facilities and salaries, they are motivated to work more with utmost dedication and efficiency finishes their targets before time that in turn helps the organization to generate more output and profit (Coffee and Palia 2016). One who functions inside the organizational structure or in the business sphere is the internal stakeholders. External stakeholders are the ones who perform their functions outside the organization (Cumming et al. 2017). Examples of external stakeholders are the consumers, shareholders, suppliers. For instance, consumers, if not satisfied with the products they use then become the negative stakeholders and they will not invest their money in that business anymore from where they do not get satisfaction. On the other side if they are satisfied consumers then it is good for that business , because when consumer gets satisfaction, then there is more demand for that product leading to more production , as a result business earns more income (Dias, Rodrigues and Craig 2017). Types of stakeholders There are two types of stakeholders, financials stakeholders and non-financial stakeholders of an organization. Financial stakeholders are those like bondholders, whereas non-financial shareholders are the employees, customers, suppliers and non-governmental organization (NGO). Primary stakeholders are the internal stakeholders who are involved in financial transactions with the organization to earn profit. Internal stakeholders are customers, suppliers and employees. Secondary stakeholders are the external stakeholders that functions in an indirect way with the organization. They are business support group, public, media group. Employees are the main source of creating profit to the organization. With their hard work and knowledge, they contribute their work to the organization. An organization appoints an employee through interview, then training and proper job designation with an aim to earn profit. Customers are those when get satisfaction from their products, then their satisfaction creates more demand for the product to the organization. More demand leads to more production of that product leading to more sales and success to the organization. Suppliers are the ones who are engaged in supplying of the resources and raw materials. It depends on the production unit, if there is growth in sales, there will be more demand for that product, thereby if there is more demands for production then there will be increase in the supply also (Denis 2016). Nongovernmental organizations are that type of organization that runs with an aim to provide social benefit to the people. Board of directors also comes under primary stakeholders or the internal stakeholders. They hold the strong powers and responsibilities to the organization. They keep the record of the workings and the functioning of the employees. Board of directors acts as pillars to the organization. It governs the organization, creates rules and regulations for the organization to maintain standards and discipline, it appoints new employees and it reviews the performances and functions of the employees. It provides finance for the resources required to meet the targets. It creates annual budget and accounting task for analyzing the performance of the organization. Finally, it provides the salary, compensation and extra incentives to the employees for their efficient work and output. Shareholders Shareholders are those types of stakeholders who hold the company shares and profits. They considered as the most powerful stakeholders compared to others. They have the right to sale and purchase the shares of the company to trade in the stock market. They nominate the directors and the shareholders for resolution purpose. If there is a declaration then the company earns dividend (Dimopoulos and Wagner 2016). They always purchase new shares given by the company. As they are the corporate heads of the organization, therefore they are the biggest dominators of the organization. They provide financial investment to the organization using the voting powers. A shareholder and a director of an organization are different. Both cannot replace each other. Shareholder owes the company properties whereas a director directs and manages the entire system of the organization. Shareholders invest money in the organization therefore that is why they are the most dominating heads of the organization. The investment organization uses the money to purchase shares from different sectors in the market with the aim of achieving profit. Proper management in the trading and investments with efficiency will create good output and income to the organization. Impact of stakeholders on the organization- A stakeholder plays a strong role in the functioning of the organization. To maintain organization profit and stability, employees must get proper benefits and recognition from their work. Efficiency in the production of the organization creates more profit. Organization must encouragement more and more in order to create employees interest. When employees are motivated, they tend to do their work with more interest and dedication. This can benefit the organization in a long way in terms of profit and reputation. Employee motivation and good working environment creates a strong positive impact on the organization. Likewise, when the customers are satisfied with the service they get, they tend to make more and more purchase from the same business unit. More selling creates more business, leading to more profit to the business. Again, customer satisfaction adds a positive impact on the business (Filatotchev, Wright and Bruton 2017). Therefore, positive impact of stakeholders will create positive impact on the organization as well. Organizational performances determined on the functioning of the various stakeholders. Reasons to place the shareholder interest above all other stakeholders The subject of report is to provide some specific evidence regarding the decision of board for placing interest above the shareholders. The board of members makes the decision on the behalf of shareholders for the benefit of the organization. They act as a fiduciary body in order to look after the financial position of the company. They have the authority to hire the executives and to cancel their job designations. Their main functions are to set desired target to achieve maximum output and profit. The board also looks after the availability of adequate resources in order to meet the desired set targets successfully (Fox et al. 2016). The head authority also aims for efficient and efficiency of utilization of various resources and technology in order to avoid wastage of resources. It aims for creating more profit and output using the updated technology and resources. In recent times, they are focusing more and more on the fiduciary activities for the betterment of the organization financial system (Goranova et al. 2017). To place the interest of the shareholders above all other stakeholders is not as per the law but an idea given by the organizational heads. The main objective of the organization is to achieve success by surviving for long term and to make profit. The aim of shareholder is not the ultimate purpose of the organization, it invest capital to the organization (Olson and Wright 2016). They act as one of the audience to the organization just like other stakeholders. Shareholders vote for the election of the board members with addition to other kinds of the stakeholders that also work for the concerns of society. From last one year, there are collection of legal memos given by law firms of 20 countries about the fiduciary powers and rights of the boards. The memos develop in collaboration with linklaters, a global organization of law (M cConnell, jj and Qi 2016). These memos will be in G20 countries that are in collaboration with a motive to earn some profit. In case of United States, according to some law, board members, separate corporate person is equal to the duty and responsibilities of the directors to shareholders (Oyewunmi et al. 2017). Whereas on the other hand according to some jurisdiction, role of shareholder is more than just a corporate head. In Brazil, fiduciary rights mean corporation authority to non-financial stakeholders like customers, suppliers. According to board members, there are many stakeholders with their rights and duties, therefore due to this there must be a statement of purpose to issue an annual statement on significant audience and materiality (Pratheepkanth, Hettihewa and Wright 2016). The statement includes companys significant audiences or stakeholders and the non-financial stakeholders as well. To elaborate the statement, it should include the workings of various organization in relation to fiduciary rights to the corporation others stakeholders, not only the shareholders (Whincop 2017). The legal memos is distributed across various countries that are Australia, Brazil, China, Chile, Columbia, Denmark, France, Germany, Hungary, India, Italy, new Zealand, Poland, Russia, Spain, Switzerland, Turkey, United Kingdom and United States. It will be available to other parts of the world soon. There is another category principle of responsible investment for the investors regarding fiduciary authority. The principle that includes law and policy for investments on investors fiduciary authority will publish soon (Yermack 2017). In sum to build, the legal issue regarding the fiduciary rights to placed above the shareholder by the organization is a good step for the betterment and good financial growth of the corporate governance. Conclusion The report gives the meaning of corporate governance with addition to the nature and impact of various stakeholders on the organization. Corporate governance is a type of organization or working place that deals with the functioning of the various stakeholders with an aim of earning maximum profit. It provides brief note on the different types of stakeholders and their nature at the organization. As the report is to provide the reason of placing the interest of various other stakeholders above the shareholder, therefore it gives a brief summary on the shareholders and their impact and contributions to the organization. Therefore, corporate governance must place the interest of shareholders above other stakeholders in order to achieve the betterment and efficiency. References Arjoon, S., 2017.

Prometheus and Pandora free essay sample

Prometheus was punished for bringing fire to man; made to remain chained to a rock, where a Roc, a legendary bird, was ordered to mangle him every day, in order for him to learn his lesson. Prometheus was rescued by the demi-god, Hercules, who was forced to do 12 acts in order to redeem himself for killing his wife and children, and after his rescue, little was said or heard of him, if anything was said at all. Prometheus was not punished for bringing what occurred in nature to us, not for that type of fire, but punished for instilling within us the fire of the gods, the fire that no man could create. What is the fire of the gods, if not the fire of nature itself, you ask, well, the fire not found in nature is something that must be found outside of or separated from nature, in one form or another. We will write a custom essay sample on Prometheus and Pandora or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page What are the things that have ridden above nature, leaned to control nature itself, to become a separate entity entirely; ask yourself what has managed to rise from pure instinct to take over what once held it captive. You will find only one answer to the question, one being, one entity, who has managed to rise up, against all odds, and take control of themselves, effectively gaining control of everything without mind; you. You alone have defied all odds, defied all natural laws, broke through the barrier of instinct to become a creature of mind, a creature of control, a creature of consciousness. Prometheus did not give us something we could forcefully take from nature, he gave us the ability to be aware, to be conscious of ourselves and our surroundings; the ability to rise up from the mindless, the ability to be rational. That is the fire spoken of when Prometheus is spoken of, the reason why the immortal was chained to a rock, left there for all of eternity as a punishment, because he gave us out mind, our very consciousness. What have we done with it, what horrors have we chosen to release upon the natural world, what destruction have we used it for, what savages we have become, where have we lost ourselves at? Pandora and her box, it was a gift from the gods, it was an object that contained emotions, but Pandora was not told of its contents, she was only informed that the box should not be opened. Prometheus had already given us his fire by this time, and we had risen enough to create pockets of civilization, but there was no emotion, so everything was natural, the fire was controlled. We were given out fire, and we looked for things to feed our fire, both to keep it going and to let it grow, because we grow as our fire grows. And our fire is all that separated us from nature, something still fresh in our mind at the time. Pandora kept her box closed for a long time, but as the time grew longer, she began to think of the box more, and how it could contain knowledge (fire) to put more distance between herself and nature. Prometheus was punished for his actions; the gods gave us a box, leaving it up to us to receive our punishment or not, letting Pandora, one of us, a typical one of us, cho ose to release that punishment, because if Pandora opened the box, than a typical one of us would have opened the box, and was met face to face with out punishment, which came pouring out of the box quickly. Whatever emotion she was struck first with caused her to snap the box shut, just as quickly as the emotions had ejected, and because of that, man must seek out the emotions left in the box, while others are a part of man. This was the point where man became individual, because man could no longer work together without getting in one another’s way, and began to lose sight of their mind and their fire. When nature came creeping up on man, because he had forgotten that staying above nature was essential, he would destroy it, because it was the one thing he feared, sinking back into mindlessness. What he did not realize was that by destroying the root of his past he was destroying the root of his present and future, for generations later, when man had lost sight of their roots, they would seek to destroy anything that threatened their place as man. That is where we are now, destroying anything we see as a threat, but what we do not realize, is that what we consider a threat is ou r very roots. Those who are productive and do nothing to destroy our roots, rather embrace them, are those who still contain the fire that Prometheus instilled within us. There are those of us who understand the fire we were given; the punishment we suffer because of our actions, and yet we endure, because we know that our gift is all we have, and that it can work in tandem with the emotions we were given. Prometheus knew the gods would punish us for his actions, so he gave us the one thing that could use against them, the mind. The gods punished us with emotions, because they knew it would most likely destroy us, but when the two are combined, the mind and emotions, it becomes something greater than what Prometheus gave us, or a worse punishment then intended. We have the power to become gods, because of Prometheus’s and the gods’ gifts, but we have lost our path, disgraced Prometheus and the vision he saw in us. We are losing ourselves back to nature, because it wants to re-claim what was rightfully its, and we fight each other because we can’t see our enemy, because all we can see is each other, but have never even thought that the solution is production, doing what one wants, and when that has become lost, moving on to something else we love.

Categories and Roles of School Governors Essays

Categories and Roles of School Governors Essays Categories and Roles of School Governors Essay Categories and Roles of School Governors Essay School governors are one of the countrys largest voluntary groups with around 300,000 contributing to strategic development and raising standards of achievement at more than 30,000 schools. School governors are members of their schools governing body, which is known as a corporate body. A corporate body has a legal identity that is separate from its members and as a result, individual governors are generally protected from personal liability as a result of the governing bodys decisions and actions provided they act onestly, reasonably and in good faith. Individual governors have no power or right to act on behalf of the governing body except where the whole governing body has delegated a specific function to that individual or where regulations specify a function is to be exercised in a particular way. School governors are drawn from different parts of the community and can be parents and staff or from the LA, the community and other groups. This helps ensure the governing body has sufficient diversity of views and experience but does not ean governors of a particular category represent that group on the governing body. For example, parent governors do not represent the parents at the school and do not report back to them. Responsibilities The governing body has a range of duties and powers and a general responsibility for the conduct of the school with a view to promoting high standards of educational achievement. Its responsibilities include but are not limited to: setting targets for pupil achievement managing the schools finances aking sure the curriculum is balanced and broadly based appointing staff reviewing staff performance and pay. The governing body has considerable discretion as to how to discharge its responsibilities but is required to constitute itself in line with the regulations and to appoint a chair and vice chair. The governing body may delegate certain of its responsibilities to certain governors or committees of governors, although in general, it is not compelled to do so.

Ribosomes and Protein Assembly

Ribosomes and Protein Assembly There are two major types of cells: prokaryotic and eukaryotic cells. Ribosomes are cell organelles that consist of RNA and proteins. They are responsible for assembling the proteins of the cell. Depending on the protein production level of a particular cell, ribosomes may number in the millions. Key Takeaways: Ribosomes Ribosomes are cell organelles that function in protein synthesis. Ribosomes in plant and animals cells are larger than those found in bacteria.Ribosomes are composed of RNA and proteins that form ribosome subunits: a large ribosome subunit and small subunit. These two subunits are produced in the nucleus and unite in the cytoplasm during protein synthesis.Free ribosomes are found suspended in the cytosol, while bound ribosomes are attached to the endoplasmic reticulum.Mitochondria and chloroplasts are capable of producing their own ribosomes. Distinguishing Characteristics Structure of a Ribosome. Interaction of a ribosome with mRNA.   ttsz/iStock/Getty Images Plus Ribosomes are typically composed of two subunits: a large subunit and a small subunit. Eukarotic ribosomes (80S), such as those in plant cells and animal cells, are larger in size than prokaryotic ribosomes (70S), such as those in bacteria. Ribosomal subunits are synthesized in the nucleolus and cross over the nuclear membrane to the cytoplasm through nuclear pores. Both ribosomal subunits join together when the ribosome attaches to messenger RNA (mRNA) during protein synthesis. Ribosomes along with another RNA molecule, transfer RNA (tRNA), help to translate the protein-coding genes in mRNA into proteins. Ribosomes link amino acids together to form polypeptide chains, which are further modified before becoming functional proteins. Location in the Cell Ribosomes can be found attached to the endoplasmic reticulum or free within the cytoplasm.   ttsz/iStock/Getty Images Plus There are two places where ribosomes commonly exist within a eukaryotic cell: suspended in the cytosol and bound to the endoplasmic reticulum. These ribosomes are called free ribosomes and bound ribosomes respectively. In both cases, the ribosomes usually form aggregates called polysomes or polyribosomes during protein synthesis. Polyribosomes are clusters of ribosomes that attach to a mRNA molecule during protein synthesis. This allows for multiple copies of a protein to be synthesized at once from a single mRNA molecule. Free ribosomes usually make proteins that will function in the cytosol (fluid component of the cytoplasm), while bound ribosomes usually make proteins that are exported from the cell or included in the cells membranes. Interestingly enough, free ribosomes and bound ribosomes are interchangeable and the cell can change their numbers according to metabolic needs. Organelles such as mitochondria and chloroplasts in eukaryotic organisms have their own ribosomes. Ribosomes in these organelles are more like ribosomes found in bacteria with regard to size. The subunits comprising ribosomes in mitochondria and chloroplasts are smaller (30S to 50S) than the subunits of ribosomes found throughout the rest of the cell (40S to 60S). Ribosomes and Protein Assembly Ribosomes interact with mRNA to produce proteins in a process called translation.   ttsz/iStock/Getty Images Plus Protein synthesis occurs by the processes of transcription and translation. In transcription, the genetic code contained within DNA is transcribed into an RNA version of the code known as messenger RNA (mRNA). The mRNA transcript is transported from the nucleus to the cytoplasm where it undergoes translation. In translation, a growing amino acid chain, also called a polypeptide chain, is produced. Ribosomes help to translate mRNA by binding to the molecule and linking amino acids together to produce a polypeptide chain. The polypeptide chain eventually becomes a fully functioning protein. Proteins are very important biological polymers in our cells as they are involved in virtually all cell functions. There are some differences between protein synthesis in eukaryotes and prokaryotes. Since eukaryotic ribosomes are larger than those in prokaryotes, they require more protein components. Other differences include different initiator amino acid sequences to start protein synthesis as well as different elongation and termination factors. Eukaryotic Cell Structures This is a diagram of an animal cell. colematt/iStock/Getty Images Plus   Ribosomes are only one type of cell organelle. The following cell structures can also be found in a typical animal eukaryotic cell: Centrioles - help to organize the assembly of microtubules.​Chromosomes - house cellular DNA.​Cilia and Flagella - aid in cellular locomotion.​Cell Membrane - protects the integrity of the interior of the cell.​Endoplasmic Reticulum - synthesizes carbohydrates and lipids.​Golgi Complex - manufactures, stores and ships certain cellular products.​Lysosomes - digest cellular macromolecules.​Mitochondria - provide energy for the cell.​Nucleus - controls cell growth and reproduction.Peroxisomes - detoxify alcohol, form bile acid, and use oxygen to break down fats.

Psychology human development Essay Example | Topics and Well Written Essays - 1000 words

Psychology human development - Essay Example It would elaborate over the human development theories applied to the individual with respect to her interactions and behaviors observed. Location The subject is observed in a playground of a club that the family visits often. The playground has swings and other recreational equipment such as see-saw, slide, monkey bars and overhead ladder for children. The children found in the playground are usually between the ages of 3 to 11 years old. The subject visits the playground with her mother who usually sits on the benches with mothers of other children. Subject The subject of this naturalistic observation is a girl between the age of four and six years old. She is the eldest child with a younger brother who is between three to five years in age. During the observation, the subject showed a variation in behavior and opened up gradually. The observation was for about half an hour during which the mother was present at the location and was looking over the subject. However, she was in clo se proximity throughout the observation. Interactions observed The observation initiated when the subject was brought to the playground early evening accompanied by her mother. For some time, she stayed alongside her mother and observed the children who were playing on the swings and other activities. Finding comfort with her mother in a place where everyone else was unknown to her displayed her reliability over her mother. According to the development theory of Erik Erickson, this shows that the subject has overcome the stage of Trust Vs Mistrust. The subject was not reluctant to go play in the ground, but since she did not know any of the children she stayed with her mother and observed. As the subject began to interact with the children, she started the conversation about the game that they were playing. She had been observing them and went to the group where she thought she would best fit. This decision was made by her own judgment and could prove that she was demonstrating Eric kson's development theory stage of Initiative vs. Guilt. As the girls she approached were swinging, she found a common interest. She said to them that she could do it to and said "you know I can swing faster than that." The conversation did not involve asking names or any other information but they quickly started sharing their routines and talked about other games that they loved playing. The subject told them about the games that she played with her little brother and her cousins. Behaviors observed At first the child showed a shy behavior when she did not go to play with the children right away. Gradually, she moved on to the children who seemed the most similar to her. She chose to play with girls who were around her age instead of going towards boys. As the subject moved on to play with the girls, the theory of Vygotsky's about principles of guided participation and zone of proximal development could be applied as her mom encouraged her to go play on the swings. Eventually, as the child interacted with the other children she opened up and became energetic and active. She showed a competitive behavior as she said that she could also play the game that they were playing.

It was noticed that within the span of ten minutes of interaction, the child had developed close bonds with her new friends and when her mother called her for supper, she did not want to leave her friends.
