Synthesis of current research literature on young children's mathematical thinking - Essay Example Number sense is a principal Mathematical component learned in the pre-school and junior levels of education. It is a concise understanding of the meaning of numbers and manner in which these numbers relate. Therefore, the number sense is a very basic yet imperative aspect of junior Mathematics learning that is essential for understanding of the subject. The fundamental concepts of the number senses include mental number line, conceptual structure, constitutive awareness, recognition of the numbers, skills, counting, arithmetic and the feel of numbers. These key components of the numbers sense lead to a comprehensive understanding of the Mathematics subjects. The capability of children to comprehend the number sense is an essential predictor of the future competence in the subjects. Learning and understanding of the number sense concept takes a diverse approach. These methods apply to children as young as 3-4 years old in school and throughout the junior levels. However, the number sense is an intrinsic ability built upon the infant minds even before attending formal education. Due to interaction of the children with adults and other peers, this intrinsic ability remains enhanced. It is made better by the formal number sense learning in the junior school and the pre-school levels. In the formal education system, the following methods are applicable to the learning of the number sense.

Ethical Issues within Information Technology Essay

Ethical Issues within Information Technology - Essay Example Similarly social networking media is used to connect with friend and relatives and share the events of life (Reynolds, 2014). But if someone’s intention is wrong then he may use the shared data or pictures which is not right at all. Security is another important issue. Hackers can easily hack into any computer by using internet protocol and collect data to fulfill some selfish reasons. In case of online banking hackers can easily get information about the transfer of funds and money can be transferred to their desired account by their interruption. So security should be at high level while using information technology (Azari, 2003). Ownership is such kind of ethical issue which indicates the right of an original creator on his work. Information technology has made it easy to get access about any information at any given point of time. There are so many music and book sharing networks through which people can download those data and can use for their own purpose. In such cases the original creators of those works lose the credibility of their work. Extensive use of networks and internet, easy access to technology and advanced wireless telecommunication system gradually losing the control on the whole process and hacker are getting benefits from their mal practices (Brennan and Johnson, 2004). Sharing own data also hamper the accuracy level of the information. People use these data as an authentic source but sometimes they do not get the proper data for using in their work. According to the importance of these ethical issues, these can be ranked as the following order: Privacy, Security, Control, Ownership and Accuracy. Privacy, security and control are three most important parameters for reducing the practice of hacking (George, 2008). Computer crime, viruses, hacking, piracy, plagiarism these are very serious impact on the field of information technology. Current

Literature Review- Gerontology; Benefits of Physical Activity in Older Essay

Literature Review- Gerontology; Benefits of Physical Activity in Older Age - Essay Example Mees (2003) reported that in the United States â€Å"each year, musculoskeletal conditions and injuries account for about 102.3 million visits to physician offices, 10.2 million hospital outpatient visits, 25 million emergency department visits, 3 million hospitalizations, and 7.5 million procedures, and they cost an estimated $300 billion†. She goes to report that â€Å" people in their 50s notice more aches and pains after performing the same activities that were painless in their 40s, and those in their 60s cant do as much as they did in their 50s†. Because the ageing process is multidirectional and multidimensional, in examining the effect of physical activity on the process we must examine the many aspects of health that are affected as one gets older, the different types of physical activity that can be beneficial, and how can elderly people be more motivated to engage in physical activity to help them in the ageing process. Even if there is no disease present there are so many other effects on the body of ageing. Coronary artery disease, hypertension, congestive heart failure, type 2 diabetes mellitus, osteoarthritis, osteoporosis, and cognitive disorders are some of the disorders that become more prevalent as people age. Brennan (2002) describes some of the normal physiological changes that occur in the body during ageing as â€Å"changes in the cardiovascular system include decreased elasticity in blood vessel walls, increases in blood pressure, and myocardial hypertrophy resulting in decreased end-diastolic filling and cardiac output; pulmonary effects include loss of tissue elasticity as well as a gradual decline in the number of alveolar sacs†. In addition he says that â€Å"as humans age, they experience neuronal cell loss, decreases in reaction time, decreases in overall balance, and decreases in nerve conduction velocities. Aging decreases estrogen, androgen, and growth hormone levels. Rates of depression increase with

Scientific Research and Writing - Assignment Example As a result, its consumption faced the major set back in its making history. Many physicians, as well as nutritionists, warned their patients against consuming large amounts of chocolate. Recent discoveries on biologically active phenol compounds such as cocoa that are currently used in making chocolate has widely changed the perception of the society about the same. In relation to this recent breakthrough extensive and intensive research has been stimulated into looking at the effects of chocolate consumption on ageing, oxidative stress, blood pressure regulation, and in controlling atherosclerosis (Matsui, Ito, Nishimura al, 2005). This research investigates the association between chocolate consumption and the occurrence of acne among college girls from Oklahoma State University. This research seeks to establish the contributions of chocolate in the occurrence of acne among college girls from Oklahoma State University. The research also seeks to validate the hypothesis that chocolate consumption is the major cause of acne among college girls from Oklahoma State University. The null hypothesis guiding this research is that chocolate consumption is not linked to the occurrence of Acne among college girls from Oklahoma State University. 50 female students were used in this experiment. The population was picked at random and divided into five groups (again at random). Four groups will be subjected to consuming milked chocolate at the rates of 10g, 20g, 30g, and 40g respectively. The fifth group will the control group and will be subjected to 0g of chocolate consumed per day. The experiment will be done mainly during the afternoon hours when most of the students are through with their classes and are relatively willing to consume the food. The relationship between chocolate consumption and the occurrence of acne will be determined by

Genetically Modified Foods Research Paper Example | Topics and Well Written Essays - 1000 words

Genetically Modified Foods - Research Paper Example Despite this, the development of these foods has met sharp critics from various stakeholders in the field of agriculture and medicine, and this has resulted to legal debates in parliaments of various countries, United States of America included. In the production of genetically modified foods, scientists usually select desirable genes from crops, combine them and come out with crops that are more superior in regard to disease and pest attack, as well as production. This is contrary to traditional food reproduction technology, in which unrelated crops were used. The cliche in the technology, as argued by opponents is based on the idea that recombining inter-species genes do not have ways of evaluating the potential threats and long-term effects on the consumption of genetically modified foods by living organisms. Since food affects each and every one of us, the discussion on food safety is of great importance to all humankind, and thus proper evaluation of both thee merits and demerit s associated with the technology is necessary. This essay seeks to outline the merits and demerits of genetically modified foods, and argue that the merits outweigh the demerits, and thus production of foods using this technology should be encouraged. Advantages of genetically modified foods To adapt to the technology of GMO’s, consumers need to be well informed on all aspects of the food starting from its production to preparation and consumption. In this regard, the consumers also need to be informed on the nutrition levels of different foods in order to ensure they purchase and consume foods that meet their health requirements. Opponents argue that GMO’s harm other organisms, human included; the recombination of genes may at times be ineffective and lead to the production of poisonous foods, which when consumed can be fatal. This is contrary to the current standards as all genetically food are tested against health standards before being released to the market. In t he production of genetically modified foods, the recombination of genes is strived to ensure that the crops are less exposed to pest and disease attacks. This is beneficial to the farmers as it reduces their cost of production and consequently increase yields and return. Therefore, the farmers can use the saved money in meeting other economic demands, which is also necessary for the economic development of a country (Skinner and Liang 12-78). On this point, opponent base their argument on the taste of foods and argue that genetically modified food have bad taste in comparison to natural foods. Although the taste of foods affects the appetitive of an individual, the nutritional value of the food is more important and thus their argument does not hold sound ground for an argument. Our ecology is very important in ensuring that all life of living organisms is sustained, and chemical components usually affect our ecology by tampering with the water systems as well as the exposure to che micals, which have adverse effects on humans, as well as animals (Shepard 34). Through the production of genetically modified foods, fewer chemicals are used, and this ensures that humans are less exposed to chemical hazards, as well as our environment remains unpolluted. Opponents argue that since genetically modified food are not good for human consumption, their production may lead to cross-pollination thus making it hard to identify genetically modified foods. Drought and other natural disasters have become a common occurrence in the recent past, and this has led to various organizations across the world striving to innovate new means of producing high yields in crop production

Marketing Communications Memo Essay Example for Free

Marketing Communications Memo Essay This year this organization has elected to erect a monument to honor the fallen military heroes of Jacksonville, Florida. Some demographics of this large city are its’ multigenerational and diverse ethnic population, varied socioeconomic span, and of course, the large military representation, both active duty, retired, veterans, and their families. The location of Jacksonville in northeast Florida is a great stopover spot for tourists making their way to Orlando or Tampa and the snowbirds on their journey to southern Florida for the winter. The location of the monument should be centralized and near a major highway, possibly Interstate 95 between Interstate 10 and Interstate 295 South. Jacksonville, Florida is a military town and rich in its military history. According to United States Census Bureau QuickFacts (Jacksonville, 2008-2012) approximately 81,000 veterans live here. This number represents 10.5% of the total Jacksonville population. When including Orange Park and Jacksonville Beach to these numbers the veterans’ total number increases to nearly 85,000. This number is not reflective of the family members surrounding the veterans. The QuickFacts sheet goes on to state that the average household in Jacksonville, Jacksonville Beach, and Orange Park, is approximately 2.50 persons. The number of individuals living in the greater Jacksonville, Florida area directly related to the military member adds another 127,500 people for a total of 170,000 (QuickFacts Orange Park, QuickFacts Jacksonville Beach QuickFacts Jacksonville, 2008-2012). We will want to choose a central location for the monument as Jacksonville, Florida has the greatest land mass in the continental United States with 885 square miles (Insider’s Guide to Jacksonville, Florida, 2014). By centralizing the location we can attract as many of Jacksonville’s residents to visit the monument. We must also take into consideration the ease of access to the monument for out of state visitors. If the location is too complicated to get to many people will not visit the site. The monument site will also have a visitor/gift shop with smaller images of the Fallen Heroes Monument for sale, along with military memorabilia of the two naval military installations, Naval Air Station Jacksonville and Naval Station Mayport, and Marine Corps Support Facility Blount Island Command along with military collectables. The various National Guards outfits along with the Coast Guard will be represented as well. The gift store will be maintain and staffed by Naval Air Station Jacksonville and proceeds will help with the upkeep of the monument. We will build the store as part of the monument site. The City of Jacksonville has donated the land in the name of the local fallen heroes. The project hopes to capture national attention with its innovative design and availability of military collectables. We want not just the Jacksonville, Florida residents to take pride in this monument but the State of Florida and our nation. Fundraising will be accomplished by reaching out to local military and veteran organizations. The Veterans of Foreign War, American Legion, Student Veterans of America, and American Veterans are all onboard to help with fundraising events like car washes, cook-outs, and large yard sales. We have also partnered with the local motorcycle clubs in Jacksonville, Florida who have scheduled several Saturday rides throughout the state. Historically the bikers clubs have donated large sums of money to events such as ours. The Jacksonville Sheriff’s Office and Jacksonville Fire Department are also collecting donations to help defray the total cost of the monument. Naval Station Mayport and Naval Air Station Jacksonville will have golf tournaments to support the building of the monument. Grants from the City of Jacksonville and from the State of Florida have been pledged.  There will be a website featuring the future monument and donations can be accepted there as well. Military personnel come from all ages, racial ethnicities, socioeconomic levels, and religious backgrounds; it is a fair assessment to predict that the visitors to the monument will be of the same diversity. The marketing direction will be of one from pride in our nations’ military men and women, the good work they do the world over, and the sacrifices they have given. The local community is fully committed to the project and is evident by the large number of private contributors. References: Insider’s Guide to Jacksonville, Florida. (2014).
