United States Abortion Laws Pro Choice - 1252 Words

United States Abortion Laws Pro-life versus pro-choice has always been a controversial issue due to religious reasons and our countries constitutional rights. The woman’s right to have a say on her pregnancy has slowly progressed throughout our countries history, while only allowing women the right to make their own choice on whether or not to keep their unborn child within the past 50 years. â€Å"The 1973 Roe v. Wade decision guaranteed a woman s right to an abortion,† states Judith S. Baughman, editor of American Decades. However, this was not always the case and still causes controversy among many people living in America due to religious reasons. Those who follow specific religions argue that abortion is a murderous act and that it is the government’s duty to protect all life. On the other hand though, the other side believes that it should be the woman’s choice on whether or not to keep her child. This is because it is her own body and she has the right to do as she please with it. No matter what the woman decides though, both sides make strong points and raise questions to what actually should be the right decision. â€Å"When you deny me a means to end my unwanted pregnancy, you deny me the opportunity to participate in society in the way that my brother or husband can. Better nurseries, better financial support can mitigate some of the consequences of motherhood—but nothing can mitigate the impact of pregnancy itself, which is why women need the means to end it† mentionsShow MoreRelatedEssay on Should Abortion Be Determined by the State or the Mother?1414 Words   |  6 PagesHistory and overview of the Policy Issue Should Abortion be determined by the State or Mother?

Differences Between the Excitation-Contraction Coupling Mechanism Between Skeletal and Cardiac Muscles free essay sample

Outline the differences between the excitation-contraction coupling mechanism between skeletal and cardiac muscles. Excitation-contraction coupling is the combination of the electrical and mechanical events in the muscle fibres and is related by the release of calcium from the sarcoplasmic reticulum. (Silverthorn, 2007) In the skeletal muscle, action potential in the nerves is generated when the somatic motor neurons releases the neurotransmitter acetylcholine (ACh), at the neuromuscular junction. This initiates muscle action potential which is then transmitted to the t-tubules. Action potential in the t-tubules leads to the release of calcium in the sarcoplasmic reticulum triggering muscle contraction. In the cardiac muscles, the initial depolarisation in sino-atrial node initiates the action potential in the muscles. This is then transmitted to T-Tubule which leads to calcium influx from extracellular space. This leads to the sarcoplasmic reticulum releasing calcium which causes the muscle contraction. The skeletal muscles need ACh from the somatic motor neuron, in order for skeletal muscle action potential to initiate excitation- contraction coupling. We will write a custom essay sample on Differences Between the Excitation-Contraction Coupling Mechanism Between Skeletal and Cardiac Muscles or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In cardiac muscles, the action potential also initiates EC coupling, but it originates impulsively in the hearts pace maker cells and spreads via gap junctions. (Richard and Pocock, 2006) The skeletal muscles and cardiac muscles differ mainly in mechanisms by which the depolarisation in the membrane leads to the release of Ca2+. In the skeletal muscle, the T-tubule membrane is coupled closely to the sarcoplasmic reticulum via the L-type calcium channel and the ryanodine receptor. However, in the cardiac muscle the Ca2+ enters via voltage-gated calcium channels which initiate a regenerative release, through activation of the Ca2+ sensitive ryanodine receptor and this initial entry triggers further release from the sarcoplasmic reticulum. (Rang and Dale, 2003) The mechanism of excitation- contraction coupling in the skeletal muscle relies on the ryanodine receptor being activated to produce the Ca2+ from the sarcoplasmic reticulum that is responsible for allowing muscle contraction. This is evident of direct coupling between the calcium channels of the T-tubule and the ryanodine receptors of the sarcoplasmic reticulum. The cardiac muscles lack T-tubules and therefore, there is no direct coupling between the plasma membrane and the sarcoplasmic reticulum. In cardiac muscles, the mechanism relies on a calcium-induced calcium release, which includes the conduction of calcium ions into the cell, causing the further release of ions. (Rang and Dale, 2003) The duration of action potential also differs for the skeletal and cardiac muscles. In the skeletal muscles, the action potential short and ends as the related twitch contraction begins. The twitch contraction is short and ends as the sarcoplasmic reticulum recovers the Ca2+ that it released. In the cardiac muscle cells, the action potential is long-lasting, and Ca2+ carries on entering the cell throughout the plateau period. As a result, the muscle cell contraction continues until the plateau ends. Therefore, the cardiac muscle contractions are nearly 10 times as long as those of skeletal muscles fibres. (Silverthorn, 2007) The cardiac muscle tissue can contract without neural stimulation, via automaticity and the specialized cardiac muscle cells called pacemaker cells control the timing of contractions.

Nike Considered Index TNS Review Final Essay Example

Nike Considered Index TNS Review Final Paper We refer to different aspects of the Index in this review, so a ascription of the approach and its parts is provided. We then give an overall assessment, followed by technical examination of different parts of the Index and commentary on its public release. 1) Insight into the environmental impacts of materials used in product creation (material scores). 2) Incentives for Nikkei to make more sustainable products, in line with the companys priorities and goals (product scores). 3) Communication of the performance results using Nines internal standards (Considered benchmarks e. . Gold standard). 4) Company targets for continual improvement (stretch goals for eating com panky-wide benchmarks of product performance by a given year e. G. All footwear to be Considered Bronze by 2011). The two main tools that make up the approach are: Assessment Method Backdating from Success The assessment has been conducted using both the sustainability principles and backdating planning method of the un ifying Framework for Strategic Sustainable Development, promoted by The Natural Step in collaboration with its international research and practitioner networks. Four science-based sustainability principles from the framework describe success in terms of the conditions added for a sustainable society, providing an operational definition of sustainability that allows for a gap analysis between where we are today and where we need to arrive at in the future. From this whole systems perspective, it needs to be clearly stated that there is no such thing as a sustainable or an unsustainable material or product; there are only sustainable material and resource management practices. Product and material sustainability claims therefore need to be viewed carefully, and as part of a journey toward sustainability one that has many possible pathways. Material Assessment Tool (MAT). This tool scores and ranks the material types used to manufacture Nikkei products from least to most preferred. The scoring is based on: Major, known supply chain environmental issues within defined impact categories. A life cycle perspective, from cradle to gate.

Third party input from specialists in materials environmental impact assessment methods. Weightings are assigned to impact categories, based on Nikkei priorities. 2. Understanding purpose and Context for the Index All tools serve a purpose. They need to be examined with their purpose in mind, and understood within the context in which they are used. To judge if this Index is a good tool for supporting Nines movement toward sustainability, Nines overall approach to sustainability must be understood: The Index has been developed to aid design and material choices as part of Nines Considered design ethos, which is part of an overall company sustainability agenda. Nikkei has long-standing commitments to sustainability in place. ; The tool is integrated into Nines innovation process. Dedicated personnel support the tools development and integration across the organization. The Index connects with, draws from and supports many other aspects of Nines sustainable business and innovation agenda (for example, procurement sustainability and audit programs, restricted substances lists, company targets and policies etc). The Considered Index. The Index rewards design innovation choices related to product creation by assigning scores to products. It encourages the selection of environmentally preferred materials (as scored in the Material Assessment Tool) as well as other practices where the designer can improve the environmental profile of the product, I. . Less waste generation, use of desired chemistry and an innovation bonus for breakthroughs that can be transferred across models. Nikkei uses these tools in a number of ways for example, aiding procurement decisions, setting of internal standards and more broadly for defining sustainable design performance. Nikkei has chosen to externally label Silver and Gold standard products, sending a signal to the consumer about Nines Considered design ethos. 2 Overall Assessment Using Sustainability as a Driver of Innovation Many traditional tools and approaches for measuring product or eternal sustainability take a static perspective, attempting to measure and assess the scale and severity of known issues and impacts today (primarily a risk avoidance approach). On their own these life cycle assessment approaches have limitations in terms of guiding strategic decision-making toward 1) sustainable resource management and 2) related business opportunities. Just as an analysis of any single move or piece of sports gear used in a football game cannot tell you who will win, one needs to look at the whole picture. Organizations wishing to use the Index and build from Nines experience should bear this in mind and ensure they build the necessary competencies and structures in place to make the best use of the results from the Index. It is therefore refreshing to see the approach Nikkei has taken combining quantitative material assessment with qualitatively- derived scores rewarding improvements in product creation. This approach highlights an evolution in thinking on measuring sustainability away from solely impact minimization and movement toward an innovation enabling strategic perspective. We believe this Index is a powerful demonstration of an overall backdating approach for enabling sustainable design innovation, not simply a set of tools for measuring movement away from environmental impacts.
