Locating Operations Essays - Economy, Money, Finance,

Locating Operations Quick revise Regional Location Businesses need to choose which regional locations are best for their operations.There are a number of factors that impact regional location. Location is based on a combination of quantitative (measurable) and qualitative factors Cost Cost of land varies between locations Costs of labour and services also vary The choice of business location therefore affects profitability Resources The availability of resource can influence location These may be natural resources or could be technological resources Businesses often cluster together in areas where there is particular expertise e.g. hi-tech organisations are centred on the M4 corridor in the UK Infrastructure Infrastructure refers to energy and transport facilities These factors influence the ease, speed and costs of production The impact of infrastructure on firms is dependent on the type of business and their needs Market Location of the market may influence location choice For some businesses it is important to be close to the market If businesses don't need to be close to their market they may need to have good access to the market Government Intervention Government grants are offered in certain areas these make the area more attractive to businesses Qualitative Factors Businesses may also consider qualitative factors including: Quality of life Image Ethical issues Analysis of Factors Businesses will use a number of methods to analyse the best location: Break even analysis They will calculate costs and revenues to see how many units they need to break even. If fixed costs e.g. rent are lower in one location than another this will reduce break even output If variable costs e.g. wages are lower in one location than another this will reduce break even output The greater the margin of safety at a particular location the lower the risk Investment Appraisal Techniques Businesses can use investment appraisal techniques such as payback, ARR and NPV to see which location is best Businesses usually select the option with the quickest payback, the highest ARR and the highest NPV Types of Location Decision Organisations have a number of different location decisions: Where to locate their business When they start up Relocation Expansion International Location Multinational businesses locate in more than one country. If you locate overseas you need to consider additional factors Why locate overseas? Businesses often locate overseas to: Exploit lower costs Benefit from less regulation Benefit from cheaper labour Use minerals / resources in a country Exploit market opportunities overseas To be closer to overseas customers To overcome protectionist trade barriers To decrease trade union power To decrease exchange rate problems Sources of finance These are how businesses get money to finance growth, to overcome working capital / cash flow problems etc. Choosing the right source of finance Businesses need to consider a number of factors when deciding what sources of finance to use External sources of finance are more expensive as you need to pay interest To use retained profits you need to get agreement from shareholders The source of finance chosen also depends on the time period and what you need the finance for The key questions that managers have to answer are: how much finance is needed whether it can be obtained internally whether it should be borrowed temporarily, with a view to paying back, or obtained as permanent (e.g. share) capital ( if borrowed) whether the loan is for the short (up to one year), medium (1-5 years) or long term. The amount and nature of this finance varies from firm to firm, and is influenced by a firm's size, its form of ownership, the type of technology currently being used within the firm, the relationship between capital and labour, the length of credit periods (taken and allowed), and the age of the firm's assets. Internal sources From inside the business e.g. directors No external body to pay Generally No time limit Internal Sources - Retained Profit Cheap and flexible Technically profit is shareholders so they need convincing its used effectively Usually okay infrequently Idea retained profit used to generate future profits and therefore used for purchase of fixed assets Opportunity cost needs to be assessed Internal Sources - Control of working capital and cashflow Working capital measures the amount of money the business

American Qualities essays

American Qualities essays American is freedom. We have many freedoms that many other countries are not as fortunate to have. As the melting pot of many races and religions, we are responsible for keeping the opportunities available that were promised by our forefathers when they founded this country: life, liberty and the pursuit of happiness. America was built on multiple cultural backgrounds fleeing persecution, poverty and lives without simple freedoms. An American quality that is seen in various works of literature stemming from our freedoms is individuality. Individuality allows us to express our inner most feelings. In the poem, The Road Not Taken, by Robert Frost, is an insightful and idealistic attempt to illustrate the paradox of free will. In the first line, Frost uses the metaphor, Two roads diverged in a yellow wood, to establish not only the hard decision a traveler must make in the poem, but in life itself. Life is like those woods because no one can clearly see or predict what will happen in the future, only hope to choose a path that will lead, one to good fortune and happiness. The freedom of choice allows us to be individuals. Many have a desire to be adventurous, yet we fear possibilities of failing if we are different from others. In Frosts poem, the road he decides to take is wanted wear. This road is not a well traveled path, and no one has taken it before. This shows that the speaker may not want to be like everyone else, a follower, but instead, chose a different path and be himself, a leader. The ce ntral idea of this poem is individuality. Frost shows that being his own person is the more difficult path. Frost shows that we should all express our feelings and be our own person, even if no one else will follow. We can see, therefore, that American qualities do imitate the essential thoughts of the American mind. Most American pe ...

Career Options for Archaeology Degrees

Career Options for Archaeology Degrees What are my career choices in archaeology? There are several levels of being an archaeologist, and where you are at in your career is related to the level of education you have and the experience you’ve received. There are two common types of archaeologists: those based at universities, and those based at cultural resource management (CRM) firms, firms that conduct archaeological investigations associated with federal construction projects. Other archaeology-related jobs are found at National Parks, Museums, and State Historical Societies. Field Technician/Crew Chief/Field Supervisor A field technician is the first paid level of field experience anyone gets in archaeology. As a field tech, you travel the world as a freelancer, excavating or conducting survey anywhere the jobs are. Like most other kinds of freelancers, you are generally on your own when it comes to health benefits, but there are benefits to the ‘travel the world on your own’ lifestyle. You can find work on CRM projects or academic projects, but in general CRM jobs are paid positions, while the academic field jobs are sometimes volunteer positions or even require tuition. A Crew Chief and Field Supervisor are Field Technicians who have had enough experience to earn additional responsibilities and better pay. You’ll need at least a Bachelors level (BA, BS) college degree in archaeology or anthropology (or be working on one) to get this job, and unpaid experience from at least one field school. Project Archaeologist/Manager A project archaeologist is the middle level of the  cultural resource manager jobs, who supervises excavations, and writes reports on excavations conducted. These are permanent jobs, and health benefits and 401K plans are common. You can work on CRM projects or academic projects, and under normal circumstances, both are paid positions. A CRM Office Manager supervises several PA/PI positions. You’ll need a Masters Degree (MA/MS) in archaeology or anthropology to get one of these jobs, and a couple of years experience as a field technician is very helpful, to be able to do the job. Principal Investigator A Principal Investigator is a Project Archaeologist with additional responsibilities. She conducts archaeological research for a cultural resource management company, writes proposals, prepares budgets, schedules projects, hires the crew, supervises archaeological survey and excavations, supervises laboratory processing and analysis and prepares as sole or co-author technical reports. PIs are typically full-time, permanent positions with benefits and some retirement plan. However, in special cases, a PI will be hired for a specific project lasting between a few months to several years. An advanced degree in anthropology or archaeology is required (MA/Ph.D.), as well as supervisory experience at the Field Supervisor level is also required for first time PIs. Academic Archaeologist The academic archaeologist or college professor is probably more familiar to most people. This person teaches classes on various archaeology, anthropology or ancient history topics at a university or college through the school year, and conducts archaeological expeditions during the summer terms. Typically a tenured faculty member teaches between two and five courses a semester to college students, mentor a select number of undergraduates/graduate students, run field schools, conduct archaeological fieldwork during the summers. Academic archaeologists can be found in Anthropology Departments, Art History Departments, Ancient History Departments, and Religious Studies Departments. But these are relatively difficult to get because there arent that many universities with more than one archaeologist on staff- there are very few Archaeology Departments outside of the larger Canadian universities. There are Adjunct positions easier to get, but they pay less and are often temporary. You’ll need a Ph.D. to get an academic job. SHPO Archaeologist A State Historical Preservation Officer (or SHPO Archaeologist) identifies, evaluates, registers, interprets and protects historic properties, from significant buildings to shipwrecked vessels. The SHPO provides communities and preservation organizations with a variety of services, training and funding opportunities. It also reviews nominations to the National Register of Historic Places and oversees the State Register of Historic Sites. Has a very large role to play in a given states public archaeology effort, and is often in political hot water. These jobs are permanent and full-time. The SHPO, him/herself, is usually an appointed position and may not be in cultural resources at all; however, most SHPO offices hire archaeologists or architectural historians to assist in the review process. Cultural Resource Lawyer A cultural resource lawyer is a specially-trained attorney who is self-employed or working for a law firm. The lawyer works with private clients such as developers, corporations, government, and individuals in connection with a variety of cultural resource-related issues that may arise. Those issues include regulations that must be followed in connection with property  development projects, ownership of cultural property, treatment of cemeteries located on the private or government-acquired property, etc. A cultural resource attorney may also be employed by a government agency to oversee all cultural resource issues that may arise, but will probably entail work in other environmental and land development areas as well. She may also be employed by a university or law school to teach subjects related to the law and cultural resources. A JD from an accredited law school is required. An undergraduate degree in Anthropology, Archaeology, Environmental Science or History is helpful, and its beneficial to take law school courses in administrative law, environmental law and litigation, real estate law and land use planning. Lab Director A laboratory director is typically a full-time position at a large CRM firm or university, with full benefits. The director is in charge of maintaining artifact collections and the analysis and processing of new artifacts as they come in out of the field. Typically, this job is filled by an archaeologist who has additional training as a museum curator. Youll need an MA in Archaeology or Museum Studies. Research Librarian Most large CRM firms have libraries- both to keep their an archive of their own reports on file, and to keep a research collection. Research librarians are typically librarians with a degree in library science: experience with archaeology is typically beneficial, but not necessary. GIS Specialist GIS Specialists (Geographic Information Systems (GIS) Analysts, GIS Technicians) are people who process spatial data for an archaeological site or sites. They need to use software to produce maps and digitize data from geographic information services in universities or large cultural resource management companies. These can be part-time temporary jobs to permanent full time, sometimes benefited. Since the 1990s, the growth of Geographic Information Systems as a career; and archaeology has not been slow in including GIS as a sub-discipline. Youll need a BA, plus specialized training; archaeology background helpful but not necessary.

Humans are rational. Critically discuss the theoretical and empirical Essay

Humans are rational. Critically discuss the theoretical and empirical evidence from psychology for and against this assertion - Essay Example These biases, such as confirmation bias, anchoring, base rate neglect and overconfidence, make up the first section of this essay. The biases are present in behavioral economics, which dictates that humans will behave in a way that is efficient for them in an economic sense, and this makes up the second portion of this essay. There is some indication that humans can be rational when it comes to domain specific tasks – such as exposing cheating or enforcing social contracts. Because of this, more study should be done regarding other domain specific tasks to indicate if there are pockets of rationality in other domain specific areas. Moreover, there is considerable thought that the irrational nature that is detected on the tests could be the result of something other than irrationality at work – such as poorly worded tests, computational errors, incorrect norms being applied, or inattention of the participants. Therefore, it is possible that humans are not as irrational a s these tests might presume. This analysis makes up the third and last portion of this essay. Discussion Reasoning is a part of cognition, which is virtually wholly made up of using inference. There is some question of whether or not reasoning has a separate cognitive system unto itself, or whether or not it is merely a part of the whole of cognition (Manktelow & Chung, 2004, p. 66). That said, reasoning must be distinguished from intuition. The main difference between reason and intuition is that reasoning is done deliberately and consciously, while intuition springs forth from the mind in a spontaneous fashion, without effort or a conscious search (Kahneman, 2003, p. 1450). Thus, when a person is doing an income tax form, he is using reasoning; when that same person revolts at eating a piece of chocolate that is the shape of a cockroach, that person is working from intuition (Kahneman, 2003, p. 1450). Reasoning is a function that is only in the higher order beings, as there has be en no evidence that reasoning is present in animals or children who are pre-verbal (Mercier & Sperber, p. 3). There are three basic types of reasoning, according to Samuels et al. (2004). They are descriptive, which describes how humans actually reason; normative, which describes how humans should reason; and evaluative, which describes the difference between how humans actually reason and how they should reason. In other words, there is an assumed standard that has been established by the normative project, so researchers interested in the evaluative project are interested in finding out how actual reasoning fit the assumed standard (Samuels et al., 2004, p. 1). These are the bases of deciding whether humans are rational or irrational – does their reasoning fit what is normative? If this is the case, then rationality can be presumed, for this would mean that the individual is making decisions that benefit him or herself. There are a series of normative rules that prescribe h ow humans should behave. One of these is cancellation, which means that a human will eliminate â€Å"any state of the world that yields the same results, regardless of one’s choice† (Tverskey & Kahneman, 1986, p. s252). Cancellation is important because only one state will be realized, which makes it easy to evaluate the other options separately for each state. Transivity is another rule, which means that each option in an

Chemistry Research Paper Example | Topics and Well Written Essays - 1750 words

Chemistry - Research Paper Example the historical background of hydrogen, its chemical formula and elements, as well as its use in compounds that make up the fabric of our very existence. Hydrogen was first produced artificially by a scientist named T. Von Hohenheim in the 16th century. In combining metals and strong acids he created a flammable gas; however he didn’t realize that what he had created was hydrogen. It wasn’t until 1671 that Robert Boyle combined iron fillings and dilute acids that the element was rediscovered. In 1766 Henry Cavendish became the first to understand that the gas produced by these combinations itself constituted a wholly unique substance. Finally, in 1783 Antoine Lavosier gave the element the moniker of hydrogen upon discovering that water was produced when the then unnamed substance was burned. (Rigden 2003) The name is derived from hudur, which means water and and gennan, meaning generate, thus giving it water generator. It was named this because of Cavendishs experiment where he combined oxygen and hydrogen. Hydrogen has the atomic number 1 and the symbol H. Hydrogen is a colorless, odorless, tasteless gas (at room tempe rature) and highly explosive. Hydrogen is the least dense gas known to man. Its melting point is 14o K and the boiling point is 20.28o K. The atomic mass of hydrogen is 1.00794 amu. Because it has only one electron it will react very quickly and, in many cases, violently. To view this, combine hydrogen with fluorine. Hydrogen has three isotopes. The first is H-1, Protium, which is stable. Protium makes up 98% of naturally occurring hydrogen. The second is H-2, Deuterium, which is also stable. Deuterium makes up 1.99% of naturally occurring hydrogen. The third is H-3, Tritium, which is radioactive. Tritium has a half-life of 12.3 years. Tritium makes up about 0.001% of naturally occurring hydrogen. Hydrogen has numerous uses, the most common of those are balloons, metal refining, and production of electricity. Some of those uses are dangerous.

Nanotheranostic Approach for Cancer Therapy and Imaging

Nanotheranostic Approach for Cancer Therapy and Imaging HER 2 conjugated multifunctional cubic phase nanoparticles (CPNPs): A nanotheranostic approach for cancer therapy and imaging Abstract Recently, cubic phase nanoparticulate systems are used as attractive vehicle in drug delivery research due to sustained release of both hydrophilic and hydrophobic drugs for cancer therapy. Currently, theranostic approach also emerged as frontier proposition for cancer therapeutics and diagnostics for better cancer management. Moreover, targeted drug delivery systems may be applied to increase the therapeutic index of the drugs and imaging agents at the targeted site. With an aim to develop a theranostic nanoformulation capable of drug delivery and imaging in a single shot, in the present study, HER 2 antibody conjugated cubic phase nanoparticles (CPNPs) were prepared by entrapping rapamycin (as a model anticancer drug) and QD 605 (as an imaging agent). The physicochemical characterisations of CPNPs were performed by different techniques. The antibody conjugated to CPNPs was confirmed by FT-IR and 1H NMR spectral analysis. In vitro studies were performed and demonstrated that, HER 2 conjugated rapamycin loaded CPNPs showed improved therapeutic efficacy than that of native rapamycin and rapamycin loaded CPNPs in HER 2 positive SKBr 3 cell line following enhanced cellular uptake through receptor mediated endocytosis. The molecular mechanisms of the particulate system on different signalling pathways were evaluated by western blot analysis. Further, the use of above system as an imaging modality was elucidated through optical imaging under in vitro system. Thus, these multifunctional CPNPs can be used as an effective targeted drug delivery system for cancer therapy and diagnosis in coming future. Introduction The life threatening disease cancer now becomes a challenge for survival worldwide due to its high mortality rate. So to achieve a better treatment modality, researchers are trying to develop new methodology for better management of cancer. Though chemotherapeutic agents are effective to some extent, however, clinical applications of these anticancer drugs are remained as a major problem due to their hydrophobic nature, low accessibility at the targeted site and dose limiting toxicity. With cancer tissues these drugs also affect the normal tissues with detrimental side effects [1, 2]. To overcome the lack of tumor specificity of cancer chemotherapy and diagnosis, till date nanomedicinal approaches have emerged as a hope for better therapeutics in cancer by using different nanocarriers like micelles, liposomes, solid lipid nanoparticles and nanoparticles consisting of biodegradable polymers etc. These approaches ultimately enhance the therapeutic potentiality of the drug in a sustaine d, controlled and targeted manner for longer period of time reducing the lethal side effects arose due to the drugs [3-5]. Recently, due to the capability to solubilise the hydrophilic, hydrophobic and amphiphilic molecules, cubic phase nanoparticulate systems are used as attractive vehicle in controlled drug delivery research [6]. In this regard, glyceryl monooleate (GMO) a synthetic lipid amphiphilic molecule approved by food and drug administration is known to form different lyotropic liquid crystalline phases depending upon water content. The cubic phase formed from GMO is a three dimensional network of curved lipid bilayers separated by intricate network of congruent water channels, now has been used for controlled drug delivery of different water soluble and insoluble drugs in the form of CPNPs [7, 8]. The use of surfactants may modulate the phase behaviour by controlling the shape and size of the nanoparticles which is an important parameter to cross different physiological barriers. In this current scenario, usually the surfactants like poly vinyl alcohol (PVA), tween 80, Pluronic F-127, Pluronic F-68, polysorbate 80 and vitamin-E TPGS etc are used as stabilisers in clinical studies to increase the therapeutic efficacy of the drug at the tumor site. In this regard, Barauskas et al have demonstrated that using Pluronic F-127 as a stabilising agent, stable aqueous nanoparticle dispersions may be obtained from the cubic phase of GMO [9]. Also it is shown that Pluronic F-127 through passive targeting can enhance the transportation of the drug towards cancerous tissues by inhibiting the drug efflux transporters [10]. Similarly, a well known natural polymer vitamin-E TPGS due to its biocompatible nature and excellent emulsifier in nanotechnology, is used for lipid-based drug delivery formulations. Moreover, also it can be used as an absorption enhancer and bioavailability promoter and facilitates the nanoparticles for carrying the drugs through gastrointestinal barrier. Apart from the above properties, recently vitamin-E TPGS is reported to inhibit p-gp pump effectively [11-13]. Recently, rapamycin and it analogs has been shown to inhibit the cancer cell growth obtained from breast cancer, pancreatic cancer, prostate cancer, lung cancer, rehabdomyosarcoma, glioblastoma, neuroblastoma, osteosarcoma, leukemia and ÃŽ ²-cell lymphoma. Rapamycin is a cytostatic agent and it shows its function by arresting the cells in G1 phase of cell cycle. The antitumor activity of rapamycin is found by blocking mTOR pathway, proposed to be an important target for treatment of cancer due to its involvement in tumorigenesis and angiogenesis on aberrant activation [14-16]. In spite of having potent anticancer effects of rapamycin, the clinical application is restricted due to its low bioavailability and hydrophobic nature [17]. In this milieu, nowadays different nanoparticulate systems are being used by different group of researchers to improve the therapeutic efficacy of rapamycin with a smaller dose for longer period of time in a controlled manner [2, 18]. Targeted drug deliver y vehicles are now emerged for improvement of treatment modality of the therapeutic agents and/or imaging agents strictly localising its pharmacological activity at the site of action through active targeting [1]. The surfaces of nanoparticles are decorated with peripheral ligands which bind specifically to the receptors those are over expressed in cancer cells arbitrating ligand-receptor interaction. Human epidermal growth factor receptor-2 (HER 2), tyrosine kinase transmembrane receptor are highly expressed in different types of cancers like breast cancer, pancreatic cancer, gastric cancer, glioblastoma, ovarian cancer etc. Humanized anti-HER2 monoclonal antibody (mAb) trastuzumab (Herceptin) was approved by U.S. Food and Drug Administration for clinical trials and it exclusively binds to HER 2 receptors preventing the cell growth in breast cancers. Targeted drug delivery with the help of mAb has drawn attention as an alternative approach for antibody mediated drug delivery of the chemotherapeutic agents for effective clinical translation [19, 20]. Nowadays optical imaging has been explored in biomedical research due to its high sensitivity, cost effectiveness, portability and lack of radiation and it shows marvellous implication by providing information for both in vitro and in vivo studies [21, 22]. The development of light emitting semiconductor nanocrystals known as quantum dots (QDs) have emerged as one of the most exciting interface of nanotechnology due to its unique optical and chemical properties over organic dyes. The unique properties of these QDs lead powerfully to study in molecular, cellular and in vivo imaging with advantages including narrow, symmetrical and tunable emission spectra according to their size and material composition, broad absorption spectra, high quantum yield, extremely photostable, more brightness and resistance to chemical degradation [23, 24]. In this study, we have formulated a theranostic nanocarrier for targeted drug delivery and imaging in treatment of cancer. Here, preparation and characterisation of HER 2 conjugated rapamycin and QD 605 loaded CPNPs based on GMO was done by blending pluronic F-127, vitamin-E TPGS, TPGS-HER 2 as a targeting moiety. Therapeutic evaluation of our formulated CPNPs was performed by taking both HER 2 positive and negative cell line through different in vitro experiments. Results confirmed that HER 2 conjugated rapamycin loaded CPNPs due to their higher uptake through receptor mediated endocytosis were more effective than that of unconjugated CPNPs and native drug treated case. Furthermore, in vitro cellular imaging study of formulated multifunctional CPNPs was validated by confocal microscopy and the results suggested that this multifunctional particulate system can act as a single bullet capable of obtaining a new concept for better therapeutics and diagnostics in cancer.
