Satie, Erik Essay Example For Students

Satie, Erik Essay Satie, ErikThe French author Erik Satie was conceived on May 17, 1866, and passed on onJuly 1, 1925, was the child of an English mother and a Parisian music distributer. He entered the Paris Conservatory in 1879 yet neglected to profit fromacademic instruction, which he set out on again just in his 40th year, when heenrolled as a student of Vincent dIndy and Albert Roussel at the Schola Cantorum. Some time before that, in any case, he had made a number out of short piano pieces, whoseeccentric titles and unfashionable but then persuading straightforwardness regarding tune werematched by an individual feeling of congruity. It is as yet an unsettled issue whetherSatie got his symphonious thoughts from his kindred understudy and companion Claude Debussy,or whether the obligation was on Debussys side. It is very clear, in any case, thatSaties classy standards impacted Debussy in the structure of his operaPelleas et Melisande and that Satie was simply the primary impact in helping Debussy tofree himself from the melodic mastery of Richard Wagner. Satie becameinterested in plainsong through his relationship with a purported Rosicruciangroup, while he earned his living as a bistro musician in Montmartre. Satie was a cognizant unpredictable and a decided adversary of allestablishments, including the melodic. The silly titles that he joined tohis little piano pieces are normal for the Bohemian mind in the Paris ofhis day. Incongruity and a misleadingly innocent disposition, an abhorrence for grandiosity ofall sorts, and an instinctual mystery were signs of both the man andhis music. In 1916, Satie was gotten to know by Jean Cocteau and composed the musicfor an artful dance, Parade, on which Pablo Picasso and Leonid Massine alsocollaborated. By a wide margin the most significant of Saties works is Socrate , a harshsetting for four sopranos and chamber ensemble of Platos record of the deathof Socrates. The youthful arrangers who shaped the basically Parisian groupknown as Les Six viewed Satie as a sort of tutelary virtuoso, and in 1923 one ofthem, Darius Milhaud, attempted to establish an Ecole dArcueil, named for the obscureParis suburb where Satie lived in extraordinary neediness.

Health Effects of Electromagnetic Radiation in Cellular Phones Free Essays

Wellbeing EFFECTS OF EM RADIATION IN CELLULAR PHONES Wellbeing impacts of EM radiation in phones Section 1 ( Identifying a Subject ) Distinguished subject isHealth impacts of EM radiation in mobile phones Phones convey by means of remote frequence ( RF ) transmittal in a web abiding of aerials or base Stationss. The term â€Å"cellular telephone† alludes to the confined or divided nature of the general web. Base Stationss give association with a little part. We will compose a custom paper test on Wellbeing Effects of Electromagnetic Radiation in Cellular Phones or on the other hand any comparable theme just for you Request Now The networks utilized in itinerant phone following four boss standards viz. GSM, WCDMA, UMTS, and LTE ( Nair and Morgan 89 ) . Recieving wires each piece great as the traveling French phone are two beginnings of electromagnetic radiation ( EMR ) . Radiation from the flying is commonly low however that from the French phone is increasingly extreme. There are numerous beginnings of electromagnetic radiation and this radiation has attractive each piece great as electric Fieldss. The study of the attractive each piece great as electric Fieldss has numerous tremendous advantages to mankind. It permits applied researchers to use radiation for useful and safe applications. Electromagnetic radiation is estimated in frequency as the chart beneath appears. img alt= src=https://s3-eu-west-1.amazonaws.com/aaimagestore/papers/1533416.001.png/ [ starting: Oatley 56 ] The more extended frequency has low vitality, the shorter frequency has more vitality, and in this way a potential start of ionizing radiation. The roaming telephone framework falls most of the way along the range. The vitality is the start of ionizing outcome that causes threatening neoplastic malady when in contact with human natural structure. This subject identifies with the essential develops of the class since it manages electromagnetic radiation. I discovered this subject fascinating in light of the fact that on one manus, it manages use of electromagnetisms in conveying and on the manus conceivable health effect of clients. I feel that in this occurrence, designing is viewed as a twofold edged edge. Lifes of one million a huge number of individuals known to mankind have changed because of acknowledgment of cell gadgets. Notwithstanding, there are waiting requests about the security of the gadgets. Section two ( study ) Wellbeing impacts of EM radiation in Cellular Telephones Subject Overview and Background Universally, more than 6.9 billion individuals utilize migrant telephones. Blending to International Agency for Research on Cancer, the electromagnetic Fieldss delivered by phones are perchance cancer-causing. This averment is non all around acknowledged and more research is being done to discover how traveling telephones are. World wellbeing association ( WHO ) is relied upon to carry on formal peril examination following twelvemonth to locate the full effect of introduction to PDAs electromagnetic Fieldss. None of the cutting edge engineerings is each piece inescapable as phone. In certain states, the greater part of the populace utilizes a migrant telephone gadget. The figure of wireless gadgets known to man is required to make a shocking 9 billion by 2020. The greater part of the new owners will originate from creating states where fixed phone was nonexistent before the presentation of roaming telephones. Given the huge figure of telephones in the market, each piece great as wide acknowledgment, it is of import to comprehend the effect of cell radiation on human wellbeing. Mobile phones transmit remote waves through a snare of base Stationss. The base Stationss are fundamentally reception apparatuses. The remote frequence moving edges transmitted are electromagnetic Fieldss, which are non ionizing like X raies or gamma bars. Phone remote frequence moving edges can non meddle with the body’s compound bonds. Electromagnetic radiation discharged by PDA is a signifier of radiation however non-ionizing one. It is believed that the warmth consumed by the natural structure cells and tissues trigger unnatural cell divisions just like ionizing radiation does. Radiation is dangerous to human health. From research center surveies, radiation mutagenesis causes DNA exclusions, DNA misrepair, and DNA misrecombination. Ionizing radiation makes double strand in DNA interfere. A study did on spacemans recommend that they are presented to radiation degrees of about 147.5 mSv which causes increases frequence of chromosomal variations after trip to unbounded ( David 34 ) . These abnormalities are least or missing before the flight. This recommends chromosomal deviations can be straight ascribed to vast radiation in endless. Researchers have since quite a while ago idea that one time radiation hits the cell, the Deoxyribonucleic corrosive is harmed and work simply happens when the cell can't to the full pa tch the mischief. In any case, rising grounds recommend that when cells are presented to radiation, it produces genomic precariousness. This implies radiation causes hurt that simply gets seeable in future coevalss. Mobile phones are radio frequence senders and they work 450 and 2700 MHz at their extremum inside the extent of 0.1 to 2 Wattss. Transmission happens simply when the gadget is turned on. Introduction to the electromagnetic shafts relies upon the separation between the client and the gadget. As the separation between the French phone and an individual increases, introduction to radio frequence begins to fall rapidly. At the point when a gadget is for outline 30 centimeters from the natural structure just like the example when a client is coordinating message or shoping the internet, introduction to electromagnetic Fieldss is essentially low. For negligible presentation, the best mobile phones are the authorities free 1s. Hands free PDAs permit the client to pass on when the telephone is at a protected good ways from the natural structure. In add-on to using authorities free gadgets, introduction to radio frequence radiation is low while doing a bring in a nation with great reaction. T he nature of reaction decides the entirety of intensity utilized by telephone and the low the force the lower the presentation to radio frequence field introduction. In clinics planes, PDAs are restricted in light of the fact that they can meddle with some clinical and route supplies. Wellbeing impacts of EM radiation in Cellular Telephones The wellbeing danger of itinerant telephone utilization have been concentrated broadly in the last 20 mature ages and research laborers have non had the option to set up for the last time that the use of mobile phones opens clients to risk of harmful neoplastic illness or other ailments. The central system through which the remote frequence vitality communicates with the both is tissue warming. At the point when remote frequence vitality is in enormous aggregates, natural structure tissues can possibly warm up along these lines suffering injury. Mobile phones discharges low remote frequence vitality and in this way the covering ingests the vast majority of the vitality discharged or different tissues found on the outside of the natural structure. Subsequently, cell vitality discharged outcomes in tiny temperature ascend in the encephalon or any fragile assortment meats. Past warming natural structure tissues, researchers have other than concentrated on conceivable mediation of natural structure cardinal system and the outcomes have been negative. Mobile phones remote frequence Fieldss do non meddle with electrical action inside the encephalon, rest structure, intellectual guide, or blood power per unit region. Hypothetically, remote frequence vitality at high degrees ought to meddle with the natural structure maps however at low degrees, it seems safe. remote frequence vitality at degree beneath that can do tissue warming have no effect on voluntaries concentrated by inquire about laborers in numerous surveies. One nation of worry that has been concentrated seriously is side effects of electromagnetic excessive touchiness that a few people have detailed. Surveies on these examples recommend that there is no causal connection between the utilization of phones and advancement of electromagnetic excessive touchiness status. In the short crew, PDAs frequence Fieldss have all the earmarks of being innocuous, in any event orchestrating to surveies did up until now. In any case, there are worries that there is hurt underneath the degree that can non be seen temporarily. Surveies taking a gander at the since quite a while ago run risk of remote frequence field presentation analyze conceivable relationship between encephalon tumor and use of cell gadgets. These kinds of surveies have been hindered by the way that traveling telephones became broad simply a decennary prior. Tumors normally appear numerous mature ages after the occasion that prompted unusual cell division that lead to threatening neoplastic illness. Research laborers center around occasions that become obvious after brief periods. Fitting to International Agency for Research on Cancer ( IARC ) , roaming telephone use does non increment the peril of creating conditions, for example, glioma or meningioma ( Herman 56 ) . These conditions have non expanded essentially in the last 10 mature ages since the introduction of Mobile. This aberrant grounds seem to suggest that even in the long haul, the risk of creating dangerous neoplastic sicknesses is low. IARC consider radiofrequency electromagnetic Fieldss as cancer-causing in spite of the fact that there is inadequacy of surveies that have decidedly connected radiofrequency vitality with threatening neoplastic infection. Absence of data is straight inferable from the way that mobile phones have only been in utilization for a couple of mature ages while threatening neoplastic malady creates over an extensive stretch. It is imagined that the issue will be more clear with cut as more youthful coevals that has grown up using PDAs develop holding been presented to telephone radiation for decennaries. My Personal Interest in the subject I am keen regarding this matter since it bargains issues partner to electric, m

5 Common OCD Alternative Treatments and Therapies

5 Common OCD Alternative Treatments and Therapies More in OCD Treatment Causes Symptoms and Diagnosis Types Living With OCD Related Conditions Although there are currently a number of effective medical and psychological treatments for obsessive-compulsive disorder  (OCD), these treatments dont work for everyone. As such, there has been great interest in developing new treatments for OCD or using new methods to improve the effectiveness of existing treatments.   St. Johns Wort Alternative medicines such as herbal remedies have been growing in popularity in both Europe and North America. Many people with anxiety disorders such as OCD have tried alternative therapies at one time or another. One of the most common herbal remedies for anxiety is St. Johns Wort. Because antidepressants that target the serotonin system, such as Paxil (paroxetine) and Anafranil (clomipramine), are effective in treating OCD, it has been suggested that St. Johns Wort, which is said to also have natural antidepressant qualities, could be an alternative therapy for reducing OCD symptoms. Repetitive Transcranial Magnetic Stimulation Repetitive transcranial magnetic stimulation, or rTMS, is a relatively non-invasive procedure that has received considerable attention as a possible alternative treatment to reduce OCD symptoms. Repetitive TMS involves placing a small device directly on the skull. This sealed device contains a coil of wire that carries electricity. The flow of electricity through the device causes cells in the brain called neurons to become either more or less active. The activity level of neurons has been linked to symptoms of mental illness like OCD. Supplementing Behavior Therapy With D-cycloserine   Psychotherapeutic techniques such as exposure and response prevention therapy  (ERP) are highly effective in treating symptoms of OCD. However, these treatments do not always work for everyone. Also, the challenging nature of behavior therapy and the associated cost cause many people to decline or drop out of treatment. Given this, there has been a lot of interest in identifying ways that behavior therapy can be made both more effective and accessible for more people. One possibility may be to supplement behavior therapy with medication. A medication that has generated a lot of interest with respect to this is the drug D-cycloserine. Exercise and OCD We all know that  aerobic exercise  has great physical benefits, including reduced cholesterol levels and lowered risk of heart disease and diabetes. Now there is significant evidence that physical activity may also help to reduce symptoms of mental illness. Indeed, it is now known that aerobic exercise can be used therapeutically to improve mild to moderate symptoms of depression, as well as reduce overall stress and anxiety levels. Recently, preliminary studies have also examined whether aerobic exercise is helpful in reducing the severity of OCD symptoms. Deep Brain Stimulation for OCD Although a number of medications and psychological therapies are available to treat OCD, it has been estimated that between 25% and 40% of people will not respond satisfactorily to these traditional treatments. In the past 20 years, the development of sophisticated brain imaging technologies, such as functional magnetic resonance imaging (FMRI), has led to explosive growth in our knowledge of the inner workings of the brain. Results of these investigations have begun to explain the biological and anatomical basis of OCD. In particular, these studies have suggested that treatments targeting specific circuits in the brain could be helpful in reducing OCD symptoms in those people who have severe symptoms and do not respond to traditional treatment. Deep brain stimulation may offer such alternative treatment. Find Relief With the 9 Best Online Therapy Programs

Usually bonds are measured to be those debt securities with terms to maturity of over one year. Debt issued with a maturity of less than one year is considered to be money market debt. There are many different types of bonds that can be issued. The most common bond is the conventional Bond. This is a bond paying periodic interest payments at a fixed rate over a fixed period to maturity or redemption, with the return of principal {the par or nominal value of the bond} on the maturity date. All other bonds will be variations of this basic structure. A bond is therefore a financial contract from the person or body that has issued the bond, that is, the borrowed funds. Unlike shares or equity capital, bonds carry no ownership privileges. The bond remains an interest bearing obligation of the issuer until it is repaid, which is usually on its maturity date. The some types of bonds in the European market reflect the different types of issuers and their respective requirements. Some bonds are safer investments than others. The advantage of bonds to an investor is that they represent a fixed source of current income with an assurance of repayment of the loan on maturity, Bonds issued by developed country governments are deemed to be guaranteed investments in that the final repayment is virtually certain. For a corporate bond in the event of default of the issuing entity, bondholders rank above shareholders for compensation payments, There is lower risk associated with bonds compared to shares as an investment, and therefore almost invariably a lower return in the long term. In this chapter we will provide a basic exp lanation of the various types of fixed income instruments encountered in the European markets as well as the definitions of some key terms and concepts that will assist the reader throughout the remainder of the book. Important groups of investors in these markets are briefly discussed in the last section of the chapter DESCRIPTION OF THE BASIC FEATURES A bond, like any security can be thought of as a package of cash flows,, A bonds cash flows come in two forms coupon interest payments and the maturity value or par value. In European markets many bonds deliver annual cash flows, As an illustration, consider a 6% coupon bond issued by the Spanish government that matures on 31 January 2008,The coupon rate is the rate of interest that is multiplied by the maturity value to determine the size of the bonds coupon payments, Note that this bond delivers annual coupon payment, Suppose one owns this bond in June 2003. what cash flows can the bondholder expect between now and the mat urity date assuming the maturity value is ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒâ€šÃ‚ ¬A 100 On each 31 January for the years 2004 through 2008 the bondholder will receive annual coupon payments of ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒâ€šÃ‚ ¬A 6. Moreover on the maturity date the bondholder receives the maturity value of ÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒâ€šÃ‚ ¬A 100 which is the bonds terminal cash flow, Type of Issuer A primary distinguishing feature of a bond is its issuer. The nature of the issuer will affect the way the bond is viewed in the market. There are four issuers of bonds: sovereign governments and their agencies, local government authorities, supranational bodies such as the World Bank, and corporations. Within the corporate bond market there is a wide range of issuers, each with differing abilities to satisfy their contractual obligations to investors. The largest bond markets are those of sovereign borrowers, the government bond markets. Term to Maturity The term to maturity of a bond is the number of years after which the issuer will repay the requirement, During the term the issuer will also make periodic interest payments on the debt. The maturity of a bond refers to the date that the debt will cease to exist, at which time the issuer will redeem the bond by paying the principal. The practice in the market is often to refer simply to a bonds term or maturity The provisions under which a bond is issued may allow either the issuer or investor to alter a bonds term to maturity after a set notice period, and such bonds need to be analyses in a different way. The term to maturity is an important consideration in the makeup of a bond. It indicates the time period over which the bondholder can expect to receive the coupon payments and the number of years before the principal will be paid in full, The bonds give up also depends on the term to maturity. Finally the price of a bond will change over its life as yields in the market change and as it approaches maturity. As we will discover later the volatility of a bonds price is dependent on its maturity, assuming other factors constant the longer a bonds maturity the greater the price volatility resulting from a change in market yields. Coupon Types As noted the coupon rate is the interest rate the issuer agrees to pay each year. The coupon rate is used to determine the annual coupon payment which can be delivered to the bondholder once per year or in two or more equal installments, As noted for bonds issued in European bond markets and the Eurobond markets coupon payments are made annually, Conversely in the UK US, and Japan, the usual practice is for the issuer to pay the coupon in two semiannual installments. An important exception is structured products which often deliver cash flows more frequently certain bonds do not make any coupon payments at all and these issues are known as zerocoupon bond,. A zerocoupon bond has only one cash flow which is the maturity value. Zerocoupon bonds are i ssued by corporations and governments. Security Description screen of a zerocoupon bond issued by the French bank BNP Paribus that matures March 11, 2005. Since the maturity value is AÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒâ€šÃ‚ ¬1000 the price will be at a discount to AÃÆ' ¢Ãƒ ¢Ã¢â€š ¬Ã… ¡Ãƒâ€šÃ‚ ¬ 1000, The difference between the price paid for the bond and the maturity value is the interest realized by the bondholder. One important type of zerocoupon bond is called strips. In essence strips are government zerocoupon bonds. However, strips are issued by governments directly but are created by dealer firms Conventional coupon bonds can be stripped or broken apart into a series of individual cash flows which would then trade separately as zerocoupon bonds. This is a common practice in European government bond markets.Since zerocoupon bonds can created from coupon payments or the maturity value, a distinction is made between the two. Currency Denomination The cash flows of a fixed income security can be denominated in any currency. For bonds issued by countries within the European Union the issuer typically makes both coupon payments and maturity value payments in Euros. However there is nothing that prohibits the issuer from making payments in other currencies. The bonds indenture can specify that the issuer may make payments in some other specified currency, There are some issues whose coupon payments are in one currency and whose maturity value is in another currency. An issue with this feature is called a dual currency issue . NONCONVENTIONAL BONDS The definition of bonds given earlier in this chapter referred to conventional or plain vanilla bonds. There are many variations on vanilla bonds and we can introduce a few of them here. Securitized Bonds There is a large market in bonds whose interest and principal payments are backed by an underlying cash flow from another assets,. By securitizing the asset a borrower can provide an element of cash flow backing to investors. For instance a mortgage bank can use the cash inflows it receives on its mortgage book as asset backing for an issue of bonds. Such an issue would be known as a mortgage backed security because residential mortgages rarely run to their full term, but are usually paid off earlier by homeowners the notes that are backed by mortgages are also prepaid ahead of their legal final maturity, This feature means that MBS securities are not bullet bonds like vanilla securities, but are instead known as Amortizing bonds . Bonds with Embedded Options Some bonds include a provision in their offer particulars that gives either the bondholder or the issuer an option to enforce early redemption of the bond. The most common type of option fixed in a bond is a call feature A call provision grants the issuer the right to redeem all or part of the debt before the specified maturity date. An issuing company may wish to include such a feature as it allows it to replace an old bond issue with a lower coupon rate issue if interest rates in the market have declined. As a call feature allows the issuer to change the maturity date of a bond it is considered harmful to the bondholders interests therefore the market price of the bond at any time will reflect this, A call option is included in all asset backed securities based on mortgages for obvious reasons. PRICING A CONVENTIONAL BOND The principles of pricing in the bond market are exactly the same as those in other financial markets which states that the price of any financial instrument is equal to the net present value today of all the future cash flows from the instrument In this Chapter bond pricing will be explained. this chapter we will just present the basic elements of bond pricing, ACCRUED INTEREST, CLEAN PRICE, AND DIRTY PRICE All bonds coupon paying bonds accrue interest on a daily basis and this is then paid out on the coupon date, In determination of the fair price for a bond that is not purchased on a coupon date accrued interest must be incorporated into the price. Accrued interest is the amount of interest earned by the bonds seller since the last coupon payment date. The calculation of accrued interest will differ across bonds due to day count conventions that will be discussed shortly. In all major bond markets the convention is to quote price as a clean price. This is the price of the bond as given by the present value of its cash flows but excluding coupon interest that has accrued on the bond since the last dividend payment. As all bonds accrue interest on a daily basis, even if a bond is held for only one day interest will have been earned by the bondholder. However we have referred already to a bonds all in price which is the price that is actually paid for the bond in the market. This is also known as the dirty price which is the clean price of a bond plus accrued interest. In other words the accrued interest must be added to the quote price to get the total consideration for the bond Accrual Day Count Conventions The accrued interest calculation for a bond is dependent on the day count basis specified for the bond in question. We have already seen that when bonds are traded in the market the actual consideration that changes hands is made up of the clean price of the bond together with the accrued that has accumulated on the bond since the last coupon payment these two components make up the dirty price of the bond. When calculating the accrued interest, the market will use the appropriate day count convention for that bond, A particular market will apply one of five different methods to calculate accrued interest. RISKS ASSOCIATED WITH INVESTING IN FIXED INCOME SECURITIES Risk can thought of as the possibility of unpleasant surprise. Fixed income securities expose the investors to one or more of the following types of risk (1) Interest rate risk, (2) Credit risk, (3) Call and prepayment risk, (4) Exchange rate risk, (5) Liquidity risk, (6) Inflation or purchasing power risk, Interest Rate Risk A fundamental property is that an upward change in a bonds price results in a downward move in the yield and vice versa. This result makes sense because the bonds price is the present value of the expected future cash flows. As the required yield decreases the present value of the bonds cash flows will increase, This inverse relationship embodies the major risk faced by investors in fixed income securities interest rate risk. Interest rate risk is the possibility that the value of a bond or bond portfolio will decline due to an adverse movement in interest rates, Call and Prepayment Risk As noted a bond may contain an embedded option which permits the issuer to call or retire all or part of the issue before the maturity date. The bondholder, in effect is the writer of the call option. From the bondholders perspective there are three disadvantages of the embedded call option. First relative to bond that is option free the call option introduces uncertainty into the cash flow pattern. Second since the issuer is more likely to call the bond when interest rates have fallen, if the bond is called, then the bondholder must reinvest the proceeds received at the lower interest rates. Third a callable bonds upside potential is reduced because the bond price will not rise above the price at which the issuer can call the bond. Collectively these three disadvantages are referred to as call risk. MBS and ABS that are securitized by loans where the borrower has the option to prepay are exposed to similar risks. This is called prepayment risk, Exchange Rate Risk If a European investor buys a bond whose cash flows are denominated in a currency other than euros they are exposed to an additional risk. Namely the euro denominated cash flows are dependent on the exchange rate at the time the payments are received. For example suppose a European investor purchases a US corporate bond whose payments are denominated in US dollars. If the dollar depreciates relative to the euro, then fewer euros will be received. This risk is called exchange rate risk. Thus, if an investor buys a bond in a currency other than her own, she is, in essence, making two investments an investment in the bond and an investment in the currency. Liquidity Risk Liquidity involves the ease with which investors can buy or sell securities quickly at close to their perceived true values. Liquidity risk is the risk that the investor will have to buy or sell at security at a price above or below its true value. One widely used indicator of liquidity is the size of the spread between the bid price and the ask price other things equal the wider the bid ask spread the greater the liquidity risk. For investors who buy bonds with the intent of holding them until maturity liquidity risk is of secondary importance, Inflation or Purchasing Power Risk Inflation or purchasing power risk reflects the possibility of the erosion of the purchasing power of bonds cash flows due to inflation. Bonds whose coupon payments are fixed with long maturities are especially vulnerable to this type of risk. Floaters and inflation indexed bonds have relatively low exposures to inflation risk. INVESTORS There is a large variety of players in the bond markets each trading some or all of the different instruments available to suit their own purposes. We can group the main types of investors according to the time horizon of their investment activity, Short-Term Institutional Investors Short term institutional investors include banks and building societies, money market fund managers, central banks and the treasury desks of some types of corporate. Such bodies are driven by short-term investment views, often subject to close guidelines, and will be driven by the total return available on their investments. Banks will have an additional requirement to maintain liquidity often in fulfillment of regulatory authority rules, by holding a proportion of their assets in the form of easily tradable short-term instruments, Long-Term Institutional Investors Typically long term institutional investors include pension funds and life assurance companies. Their investment horizon is long-term, reflecting the nature of their liabilities. Often they will seek to match these liabilities by holding long-dated bonds. Mixed Horizon Institutional Investors Mixed horizon institutional investors are possibly the largest category of investors and will include general insurance companies and most corporate bodies. Like banks and financial sector companies, they are also very active in the primary market, issuing bonds to finance their operations. Market Professionals Market professionals include the banks and specialist financial mediators mentioned above, firms that one would not automatically classify as investors although they will also have an investment objective. Their time horizon will range from one day to the very long term. They include the proprietary trading desks of investment banks as well as bonds market makers in securities houses and banks who are providing a service to their customers. Proprietary traders will actively position themselves in the market in order to gain trading profit, for example, in response to their view on where they think interest rate levels are headed. These participants will trade direct with other market professionals and investors, or via brokers. Market makers or traders are wholesalers in the bond markets; they make two-way prices in selected bonds. Firms will not necessarily be active market makers in all types of bonds; smaller firms often specialize in certain sectors.
