A Summation Of The Safe Medical Devices Act

The SMDA Act is an act that sanctions the progressive reporting as well as tracking the regulations for the use of the medical devices. The medical devices defined under the Act involve the devices classified within the consent of the Medical Device Regulation Act. The Act is responsible for the mandate of reporting the requirements made by the manufacturers of medical devices. The requirements hold with regards to the safety events as well as the product efficiency of the said devices. Based on the Act, the devices are classified with a substantial equivalence to the class II medical devices ( ...

Demographic aging refers to the shift of the age structure or age distribution of a population as the population moves towards older ages. The effect of demographic aging is a decline in fertility transition, reduced mortality rate of older persons, increased dependency ratio and a shrinking labor force. Historians see a great divide between the traditional and modern view of aging. In traditional societies, families maintained closer ties for their entire lives. Besides, the people kept childhood friendships active as they moved into old age and community members integrated. Cultural values entrenched a strong respect for the elderly, which ...

In the article titled, “Longevity Among Hunter- Gatherers: A Cross-Cultural Examination”, by Michael Gurven and Hillar Kaplan, the authors find that survival of Homo sapiens has gradually increased and people who lived before us, has a shorter life span than people of the current time. The longevity in this article is described as senescence-associated age of death. If human lifespan is divided into three phases: childhood, adulthood and older adult (after 40 years of age), mortality rates are higher among older adults. Lifestyle changes and better sanitation practices have helped to reduce mortality rates across all three phases of ...

Opinion on Genetic Engineering

In my opinion, genetic engineering is one of the key forces that will help humanity survive and live better lives in the future. Despite the proliferation of views against genetic engineering, I still believe that it can do more good than harm. Many people are already benefitting from it, and we cannot these benefits. Diabetic patients for example have been taking insulin to live longer. Note that the current insulin drug is prepared through genetic engineering. Nevertheless, I also believe that there should be strict rules on applying genetic engineering because I consider it a double edge sword that ...

There has been increasing awareness of the role of waste in the production of greenhouse gas emissions and its impacts on climate change. Diminishing natural resources has led to the recognition that what is discarded as waste has the potential to be reused as resources. Governmental legislation on prohibiting toxic materials and prevention and control of the volume of waste has helped in decreasing adverse environmental effects. There is a growing public awareness about waste prevention and its beneficial effects. The society has to replace the linear model of extract-produce-consume-dispose to closed Loop's approach of resource recovery and waste ...

Introduction

The negative or positive experiences of early childhood play a very significant role in the development of the social and emotional behavior of an individual. According to Fagundes, Bennett, Derry, and Kiecolt-Glaser (2011), the ability to understand the social and emotional behavior of an adult is complex because it requires one to have a comprehensive understanding of their entire lifespan (p. 40). This is because the social and emotional development of an individual are influenced by several factors that they encounter during their major stages of growth in their lifespan (McClelland, Ponitz, Messersmith, & Tominey, 2010, p. 35). Some of ...

Sleep, Memory, And Aging. The Link between Slow-Wave Sleep and Episodic Memory Changes from Younger to Older Adults. Sleep, Memory, And Aging. The Link between Slow-Wave Sleep and Episodic Memory Changes from Younger to Older Adults.

Introduction

An interesting modern healthcare development has been found in the discovery of slow wave sleep in the reactivation of episodic memories. It, however, decreases its effect while the age of the patient is increasing. Also, little research has been found on the use of slow wave sleep on the elderly with the majority of the volunteers for the test being of the younger ...

Question 1

DNA replication can be defined as the process by which during cell division the DNA duplicates itself to several copies. In this process, the first step involves the unzipping of the double helix found in the DNA structure. This is done by the helicase enzyme, which breaks hydrogen bonds holding the DNA together. When separated the two DNA strands form a replication fork with a Y shape (Craig et al. 2014). This causes the strands to be oriented in different directions, forming the leading and the lagging strands. Once the two orientations are formed, a short RNA piece called ...

Developmental psychologists study how humans develop throughout their lives. Their studies often rely on differentiating between perception and sensation, as a human develops over the course of its life. It is important to understand how these two concepts are connected and what makes them different, in order to understand problems faced by developmental psychologists. These two facets of human existence seem integrated, yet are completely different from one another. This paper will attempt to define and distinguish between perception and sensation, discuss problems for study that these concepts present developmental psychologists, and discuss practical problems that the study of ...

Abstract

The uses of radiation revolutionized medicine when experimentation on its potential applications begun. X-Ray technology, discovered by Wilhem Roentgen, is currently used as a common tool for diagnostics; Henri Becquerel, Marie Curie and Pierre Curie dedicated themselves to further investigations in the field, discovering additional radioactive materials (polonium and radium); radiation therapy is a popular treatment for cancer. This paper analyzes the historical background behind these two applications of radiation in the medical field. Moreover, the different types of radiotherapy are described (external-beam radiation therapy, internal radiation therapy). The concept of radiation homeostasis, which is the notion that low-dose ...

Parents are the first to guide children in their individual, social, academic and professional development, as they are the first point of contact for their youngsters. Even when they grow up and enter a formal educational program, parents are still important actors in providing children with education and guidance in life. This is why, it is recommended designing a family life educational (FLE) program that addresses parent education and guidance. This FLE program would provide an understanding of how parents teach and influence their children and adolescence to make sound decisions throughout their life. The program is also intended ...

In Tissenbaum and Guarente's research study, they concluded that increasing the dosage of a SIR2 gene is associated with extended lifespan of roundworms, Caenorhabditis elegans (Tissenbaum & Guarente 228). To easily understand their research study, let us discuss a little background abound longevity of C. elegans. In 1997, a research study headed by Kimura, Tissenbaum, Liu and Ruvkun found the gene that potentially regulates the longevity and diapause in Caenorhabditis elegans. In C. elegans, their life cycle after the initial larval stage can proceed to two different stages: either the reproductive stage, or the dauer diapause stage (Hu). In their ...

Going Green with Technology.

Many people are trying to find ways to save on grocery bills and electric bills. Some find it easier as well as less expensive to just plant their own crops rather than buy them. But not everyone has a beautiful home with a full front and back yard. Even now of these days those parts of the establishment are rather small and giving less room than they would three decades ago. What about the people who live in apartments and condos? They would also like to have similar experience but don’t have the room to do it. There ...

Adages are associated with a long history tracing back centuries ago, and they, therefore, are widely known by people having a shared history with no individual claiming ownership. “As the twig is bent, so grows the tree” use is claimed to have started in the 16th century where it was put that one may straighten a stick when green, and it may not be crooked. The current form of this saying can is attributed to Alexander Pope's Epistles to Several Persons (1732). Despite being pithy-short and straightforward, sayings have a deeper meaning which is utterly different from the outward ...

Explain the Life Span Perspective of Development

The life span perspective of development focuses on individuals’ development through their respective lifespan. It is concerned with who people are and how they gradually gain their identity. Research suggests that psychoanalytic theories attempt to provide insight into an individual’s lifespan development as well as the developmental stages that a person undergoes in their life (Doise, 1998). Ideally, the lifespan perspective offers useful information regarding the way environmental and hereditary factors interact to create the differences in individuals’ lifespan development. The perspective is essential in the study of human development because it provides significant insight into an individual’ ...

Use of Fossil Fuels for Power Generation and the Need for Renewable Energy

According to Nelson (2011), more than 85% of the world’s energy consumption, which is estimated at 520 exajoules, is generated through the burning of fossil fuels such as petroleum, natural gas and coal (p.19). Electric power generation from non-renewable sources will, unequivocally, result in their exhaustion and creation of a major energy crisis. For this reason, it appears primordial to shift in a greater scale to alternate power generation, such as solar, wind, hydroelectric, etc. Amongst these, Sorensen (2011) explains that though hydroelectric power does represent one of the major forms of power generation, its growth is stagnant ...

Claim

It is extremely legal for manufacturers in the United States to intentionally practice planned obsolescence in the design of their product.

Explanation for the Claim

Planned obsolescence is a business practice of deliberately designing products limiting its lifespan or making it unfashionable after a given period. The main purpose of this strategy is to make consumers feel the need to buy new products that the manufacturer will have provided. Most of the time, the products are purposely intended to fizzle out after the warranty has expired. This manufacturing strategy is widespread in America with digital device companies being the most notorious for its ...

Invented and patented by Thomas Edison in 1879, the incandescent bulb comprises of a wired filament placed inside a glass bulb (“The History”). When electricity is provided to the filament, it heats up thereby making the bulb glow and emit light (“Incandescent, LED”). The wired filament of the incandescent bulb was initially made using carbon obtained from a cotton thread that was uncoated. This filament gave the bulb a lifespan of just 14.5 hours. Later, the carbon filament was made using bamboo, which gave the bulb a longer lifespan of up to 1200 hours (“The History”). Much later, in ...

The debate on whether to consider aging either as a natural and inevitable process or as a disease has been raging on for decades. Those who consider aging a natural process such as Callahan (1990) and Fukuyama (2002) argue that the quest to extend life does not necessarily imply a better life or is inconsistent with human nature (Caplan, 2005). Conversely, contemporary scientists are increasingly adopting the view that aging is a disease because it fits the biological definition of a disease and has a distinct cause and recognizable signs and symptoms (Bulterijis, Hull, Bjork, & Roy, 2015). The fact ...

The aging process occurs during a person’s lifespan. Nobody can escape this process and it happens to everyone. Aging is associated with maturation, growth, and discovery (Cohen et al., 2015). Many abilities of human beings peak before the age of 30, but there are other abilities that continue to grow and develop throughout the life of a person. Most people who are over the age of 65 are healthy, fully independent, and happy while others start experiencing signs of deterioration. These changes are normal and not harmful. The hair thins and start turning gray and skins thins and ...

Introduction

Old age marks the end of the human life cycle and involves surpassing or nearing the set life expectancy of people. Most states have set the life expectancy of persons to be between 60 and 65 years, and this marks the termination of many life cycles. At this particular stage, we have reduced regenerative abilities as opposed to young people. Our bodies have the capacity to dispose and destroy worn out cells at a faster rate, but this is not the case in the old age where all life processes have ultimately slowed down. Bronfenbrenner, suggests that our environment ...

Abstract

This paper explores development of adolescents and young adults by involving adjustments and changes, which can vary in people of the same age. While studying their developments, I have considered emotional, social, cognitive, sensory and physical processes and even their combination. For instance, when individuals enter the puberty period, they may feel some implications for personal development and personality in whole. Although during adulthood and adolescence there are a lot of developmental aspects, wide personal variations occur because of core issues, achievements and circumstances. For example, not all people can attain stages of psychological development in early adulthood. There ...

1) Brief summary: The article focuses on research that was done regarding the effects of aging of the brain and its relationship with interactions of the brain's network. The researchers believed that there would be a positive correlation between the increased interactions among these brain networks and the healthy aging of cognitive functions. Generative models were used in order to overcome the challenges related to natural changes in the brain related to aging as well as the flexibility of neural activity. The study found that aging does in fact influence the cognitive capacities of adults. As people grow older, ...

What explains the decline in mortality in developed countries? Are there lessons to be learned in relation to the poor in developing countries today? I. Introduction

In general, the mortality level is deservedly considered to be among one of the characteristics that reveals both economic and social health of the certain state and that clearly describes the effectiveness of the policies that governments get used to adopt. In this context, the most significant particular demographic indicators are commonly the following: 1) Infant mortality rate; 2) Maternal mortality rate; 3) Mortality amid able-bodied citizens; 4) Mortality caused by external factors; ...

Adapting Sports for the Younger Performer

Introduction Many kids want to be famous athletes when they are young and will work towards that faraway goal depending on how long their desire persists. Some will realize the hard work and dedication that is required is too much and will seek an easier or different course in life to follow. Others will try even harder, but only a select few will find that they possess the skills to transcend to the next level of competition. For all young performers that compete it is important to recognize that kids are not to be treated as adults despite their ...

Introduction

Development is defined as the act of adaptation while personality development basically refers to the mental, emotional, psychological, temperamental and behavioral growth that one acquires (Schulz and Heckhausen, 1996). Also, personality development can be described as the averagely constant and stable features and characteristics a person bears with time (Alea, Diehl and Bluck, 2004). Personality development usually is an attribute associated with age and experience.

Success can be defined as the achievement or realization of desired goals or objectives hoped for. On the other hand, successful ageing is basically the eminent and prosperous growth in personality, self-concept and values acquired ...

Abstract

The lifespan development study came as a result of Charles Darwin’s aspiration to appreciate the concept of evolution. Stanley Hall published the first study of children; his book pioneered the models and adolescence to scientists (Boyd & Bee, 2006). Lifespan involves the period from conception all through to death. This essay tends to describe the growth and development of human beings during the lifespan period at the same time describing each stage’s attributes consistent with the lifespan perceptions. The various human development domains and periods are acknowledged and modern apprehensions as connected to lifespan development are also identified.

Introduction

...

Life span development is a window into the nature of human development from conception to death. The life span perspective involves seven basic contentions: development is lifelong, covers the various life aspects , multidirectional, plastic, historically embedded, multidisciplinary, and contextual (Papaya, 1981)

Development is lifelong. Development includes changes that take place from conception to death.

Development covers various aspects of life. Development consists of biological,cognitive, and social dimensions.

Development is plastic. Depending on the individuals life conditions, development may take many paths.

Development is embedded in history. People's life paths are influenced by the happenings of that particular time.

The human development ...

When people make their choices in life, they are influenced by the society that surrounds them by changing their social conditions in ways that may at some point encumber or even support their life with family. Interplay exists between an individual’s family and the society, and throughout the adulthood stage, an individual makes choices that are family related. Development is the movement, growth, and transition made by an individual from one state to another in life. This research has been able to state clearly the stages made by people who are developing from one stage to another. This ...
