The Elderly and Malnutrition Essay -- Health Nutrition Pyramid Diet

The Elderly and Malnutrition      Ã‚  Ã‚  Ã‚  Ã‚   At any age, nutrition is vital to maintaining health and enhancing quality of life.   However, achieving good nutrition can be especially difficult for the elderly, the fastest growing portion of America's population.   Many factors, including physiological changes, changes in nutritional needs, illness and physical limitations, food-medication interactions, depression and loneliness, and food insecurity are common causes of malnutrition in the elderly.   This paper will explore factors affecting elderly nutrition, provide suggestions for obtaining and maintaining good nutrition after age 65, and describe the services available to help the elderly meet their nutritional needs.  Ã‚        Ã‚  Ã‚  Ã‚  Ã‚   A number of factors influence the nutritional status of the elderly.   First, several physiological changes impact elderly nutritional requirements.   Changes in taste and smell may decrease an individual's appetite or desire for food.   Gastro-intestinal motility decreases with age and may lead to constipation, decreased nutrient absorption, and a decrease in fat and protein absorption.   Metabolism also slows with age; this results in a decrease of lean body mass and an increase in body fat (8).   Lastly, bone mass decreases, leaving the elderly vulnerable to bone fractures from falls and osteoporosis.      Ã‚  Ã‚  Ã‚  Ã‚   Ultimately, these physiological changes result in different nutritional needs for the elderly.   The Food and Nutrition Board of the National Academy of Sciences issues the Recommended Daily Allowances for healthy people over the age of 51.   However, these RDAs are limited in that they have been derived from studies of younger, healthy populations and do not account ... ...;. 5) Good Nutrition is Ageless.

Challenges of Microfinance Banking in Nigeria

CHALLENGES OF MICROFINANCE BANKING IN NIGERIA-1 Nigerians, like many other Africans are generally known as their brother’s keepers in view of the extended family system. But when truly analyzed, there is a possibility that this may not be so? Perhaps a hypothetical deep may reveal that not up to 10% of Nigerians would invest in ventures or people that would yield them nothing in return and here I mean, â€Å"Returns in the short run or in the immediate†. The returns may be financial, emotional, spiritual, relational or social. But fact is, there is something the investors expect in return when they give and these could include being worshipped as personal heroes, fear of harassments, fear of being harmed, for family ties, religious ties, being perceived as a caring corporate organization with the intent of bigger business tickets etc. Hardly do the â€Å"Nigerian rich† set aside a portion of their riches for the â€Å"unknown poor† or for true charity except such gifts are meant to make them be seen by the Society or Divinity as good or circumvent some threatening harms etc. This anti-poor behavior is projected into organizations; corporate, social, religious and sometimes even Government and parastatals as people see only the short end of developments without heeding the social woes of economic imbalance and insecurity. Consequent upon my above beliefs, I may classify the challenges of Microfinance banking in Nigeria under five (5) main headings: 1. COMMUNICATION GAPS AND INADEQUATE AWARENESS As a background to the undeniable problem of communication for effective microfinance, listen to this quote by Stan Paris on his article on Microfinance As A Means of Reaching The People â€Å"Problems of communication are endemic in the industry, dating back to what could be considered the first micro-loan. In 1976, Muhammad Yunus, a young economics professor at Chittagong University, Bangladesh, took his students into a small village where he discovered a woman crafting beautiful stools out of bamboo. He inquired what the woman earned for her work after repaying the trader from hom she borrowed. She told him she earned the equivalent of 2 cents in net profit. Yunus was appalled. He wanted to help her find a means of financing that would allow her to make more net profit. But, first, Yunus had an enormous communication barrier to overcome. That was a time in Bangladesh when women didn't touch money and didn't talk to men, explains Sam Daley-Harris, director of the Microcredit Summi t Campaign, an important facilitator of dialogue in the industry. Yunus had to have a female student ask the woman a question, then return to tell him the answer. There were barriers of communication even in explaining the value proposition. † Truth is that today, communication barriers exists heavily in Nigeria particularly given that even within a State, there exist as many languages and dialects as exists ethnic groups. Also, high level of illiteracy even among the educated who fails to read important things that would enable them take positive steps towards personal, interpersonal and national development. I recall given many flyers of Elim Kit â€Å"n† Kin to a friend of mine who is well educated and is on a billion naira business locally and international. This guy was in a church service when a play-lets on Kit â€Å"n† Kin was delivered by a group of young people. But after the service, he approached me on how to go about empowering a friend he wants to help and when I suggested kit â€Å"n† Kin, he asked me what that was? Obviously, my educated friend neither read the flyer which is comprehensive and explanatory nor listened to the play†¦.. here lies the problem of many Nigerians of all classes, hence my concern for communication on micro financing. Lets now look at some of areas of specific communication challenges in Nigerian Microbanking In adequate awareness campaigns and supports by the regulators: The CBN and the NDIC as Federal Government’s engine of economic development need to do greater and continuous campaigns to all stake holders; investors, universal banks, the banking public, the micro targeted poor and low-medium scale entrepreneurs until the micro banking ideas sink in the society and gets well accepted. I hear and read the Governor of CBN assuring the public of safety of the Consolidated Banks. But the Similar truths and campaigns should also be carried for the microfinance industry Lack of trust by the oor themselves who believe that the microfinance banks are just like the unregulated community banks and unregulated finance houses. Going by the antecedents of the banking industry in general, no one would blame the people for lack of trust. Only effective and far-reaching campaigns and exhibited trust in the microfinance banks by the government and the regulators can achieve this desirable confi dence. An Uneducated Population: A critical ill of the populace in Nigeria is the bottom, bottom level of poor education of the people. A country where less than 10% of the populace pays attention to the print media, less than 20% listen or watch educative audio-visuals is a great challenge to information dissemination. Incidentally, the literally â€Å"very† educated people do not read handbills and communicative documents that deal with those things like microfinance banking since they have no interest in such activities. A survey of how many people would read this documentary would shock you even if the Guardian Newspapers circulate it free to just the middle and upper classers. This attitude is worse with the targeted microfinance clients. They are more interested in chasing their â€Å"kobos† than reading or listening to programs that would help them build up and improve on their standards of living The Active Poor’s Current Preference for Gifts Than Loans. Generally, a hindrance to economic development in Nigeria is the gift preference of the poor as a culture from political and religious biases. The politicians, the rich in religious circles, towns and villages all over Nigeria have cultured the poor to beggarliness and dependence rather than empowerment for productive and financial independence. Gifts are not usually regarded as re-investment treasures by the receivers. This is why givers ought to challenge the receivers to effectively put their gifts to work by rendering these helps through microfinance banks. Products such as ELIM Kit â€Å"n† Kin are meant for well intended givers to assist the poor live above perpetual begging. It is known internationally that micro-financing is not charity. Micro funds are meant for the productive activities of the beneficiaries. Consequently, only people who fall within the active poor or low income earners who are willing and able to utilize the loans for productive activities and repay both interest and capital are the bona-fide candidates for microfinance. 2. ANTI-POOR ATTITUDES OF NIGERIANS Dearth of quality investments in microfinance banks:. Most surplus spenders and investors in Nigeria, because of the lethargic attitudes to the poor, would not invest in Micro finance banks. They prefer to invest in the â€Å"billion naira profit making consolidated banks†. Again, Nigeria investors are coasted by the quick-return and trader-like attitudes which surely does not result in a meaningful development for the Nation. They are therefore unable to go through the gestation period required in the young microfinance industry for their investments to start yielding good dividends. The Grameen Bank of Mohammad Yunus did not start making profit in year one, but today, that bank is one of the most profitable financial institutions in Asia and yet, it is a financial institution with classic recognition for adding the greatest value to humanity. Snobbish and selfish attitudes by the financially well to do Nigerians. Hopefully, good campaigns and direct involvement by the who is who in Nigeria would solve the current snub by the rich on poverty alleviation programs and enable these categories of Nigerians see that Microfinance is both a good and rewarding investment and a good development project that directly and indirectly impact their lives. 3. INSUFFICIENT SUPPORT FROM THE REGULATORS AND GOVERNMENTS Poor buy-ins and competitive approaches by the State Governments and Local Governments. The policy direction towards the millennium development goals is that one percent of the annual votes of the State and Local Governments should be channeled to Microfinance banks for on-lending to the poor and low to medium scale entrepreneurs. So far, very few states have taken steps to get this started. Lagos state is a shinning example that has taken the lead to effectively and efficiently put microfinance banking into focus. Their microfinance institutionalization, the dept of involvement of the Ministry of Women Affairs and Poverty Alleviation in developmental activities at the grassroots is equaled by non I know in Nigeria of today. This Ministry is not just a moribund ministry; it is a ministry that is empowered and achieving evidential results. This ministry needs to be copied by every state in Nigeria. Today, some 800 microfinance banks are established in Nigeria, but some states rather than use the services of these banks licensed by the CBN, choose to find a round about way of dealing with mega banks or establishing their â€Å"owned† micro credit institutions. It is my candid opinion that government involvements in microfinance banking would be counterproductive as they should concern themselves with policy formulation and control rather than implementation. How can someone formulate policies, implement it and effectively control it? Nigerian Microfinance banks have what it takes to manage micro funds for states and international bodies and should be given the chance to do so under strict supervision and controls.

Calculating Torque With Examples

When studying how objects rotate, it quickly becomes necessary to figure out how a given force results in a change in the rotational motion. The tendency of a force to cause or change rotational motion is called torque, and its one of the most important concepts to understand in resolving rotational motion situations. The Meaning of Torque Torque (also called moment — mostly by engineers) is calculated by multiplying force and distance. The SI units of torque are newton-meters, or N*m (even though these units are the same as Joules, torque isnt work or energy, so should just be newton-meters). In calculations, torque is represented by the Greek letter tau: Ï„. Torque is a vector quantity, meaning it has both a direction and a magnitude. This is honestly one of the trickiest parts of working with torque because it is calculated using a vector product, which means you have to apply the right-hand rule. In this case, take your right hand and curl the fingers of your hand in the direction of rotation caused by the force. The thumb of your right hand now points in the direction of the torque vector. (This can occasionally feel slightly silly, as youre holding your hand up and pantomiming in order to figure out the result of a mathematical equation, but its the best way to visualize the direction of the vector.) The vector formula that yields the torque vector Ï„ is: Ï„ r Ãâ€" F The vector r is the position vector with respect to an origin on the axis of rotation (This axis is the Ï„ on the graphic). This is a vector with a magnitude of the distance from where the force is applied to the axis of rotation. It points from the axis of rotation toward the point where the force is applied. The magnitude of the vector is calculated based upon ÃŽ ¸, which is the angle difference between r and F, using the formula: Ï„ rFsin(ÃŽ ¸) Special Cases of Torque A couple of key points about the above equation, with some benchmark values of ÃŽ ¸: ÃŽ ¸ 0 ° (or 0 radians) - The force vector is pointing out in the same direction as r. As you might guess, this is a situation where the force will not cause any rotation around the axis ... and the mathematics bears this out. Since sin(0) 0, this situation results in Ï„ 0.ÃŽ ¸ 180 ° (or Ï€ radians) - This is a situation where the force vector points directly into r. Again, shoving toward the axis of rotation isnt going to cause any rotation either and, once again, the mathematics supports this intuition. Since sin(180 °) 0, the value of the torque is once again Ï„ 0.ÃŽ ¸ 90 ° (or Ï€/2 radians) - Here, the force vector is perpendicular to the position vector. This seems like the most effective way that you could push on the object to get an increase in rotation, but does the mathematics support this? Well, sin(90 °) 1, which is the maximum value that the sine function can reach, yielding a result of Ï„ rF. In other words, a force applied at any other angle would provide less torque than when it is applied at 90 degrees.The same argument as above applies to cases of ÃŽ ¸ -90 ° (or -Ï€/2 radians), but with a value of sin(-90 °) -1 resulting in the maximum torque in the opposite direction. Torque Example Lets consider an example where youre applying a vertical force downward, such as when trying to loosen the lug nuts on a flat tire by stepping on the lug wrench. In this situation, the ideal situation is to have the lug wrench perfectly horizontal, so that you can step on the end of it and get the maximum torque. Unfortunately, that doesnt work. Instead, the lug wrench fits onto the lug nuts so that it is at a 15% incline to the horizontal. The lug wrench is 0.60 m long until the end, where you apply your full weight of 900 N. What is the magnitude of the torque? What about direction?: Applying the lefty-loosey, righty-tighty rule, you will want to have the lug nut rotating to the left - counter-clockwise - in order to loosen it. Using your right hand and curling your fingers in the counter-clockwise direction, the thumb sticks out. So the direction of the torque is away from the tires ... which is also direction you want the lug nuts to ultimately go. To begin calculating the value of the torque, you have to realize that theres a slightly misleading point in the above set-up. (This is a common problem in these situations.) Note that the 15% mentioned above is the incline from the horizontal, but thats not the angle ÃŽ ¸. The angle between r and F has to be calculated. Theres a 15 ° incline from the horizontal plus a 90 ° distance from the horizontal to the downward force vector, resulting in a total of 105 ° as the value of ÃŽ ¸. Thats the only variable that requires set-up, so with that in place we just assign the other variable values: ÃŽ ¸ 105 °r 0.60 mF 900 N Ï„ rF sin(ÃŽ ¸) (0.60 m)(900 N)sin(105 °) 540 Ãâ€" 0.097 Nm 520 Nm Note that the above answer involved maintaining only two significant figures, so it is rounded. Torque and Angular Acceleration The above equations are particularly helpful when there is a single known force acting on an object, but there are many situations where a rotation can be caused by a force that cannot easily be measured (or perhaps many such forces). Here, the torque often isnt calculated directly, but can instead be calculated in reference to the total angular acceleration, ÃŽ ±, that the object undergoes. This relationship is given by the following equation: ÃŽ £Ãâ€ž - The net sum of all torque acting on the objectI - the moment of inertia, which represents the objects resistance to a change in angular velocityÃŽ ± - angular acceleration
