Uplifting news for their bank adjusts maybe yet not uplifting news for your wellbeing, this is the reason you should be educated regarding the benefits of natural food. Did you realize that in the event that you expended a normal apple you would eat more than 30 pesticides, considerably after you have washed it? Natural food is known to contain half more supplements, minerals and nutrients than produce that has been seriously cultivated. You should gobble more natural product these days to make up the inadequacy, yet sadly that implies eating more synthetic compounds, progressively negative effects on your wellbeing eating something that ought to be beneficial for you! Some all the more surprising realities now. Pesticides in food have been connected to numerous illnesses including: ? Disease ?Obesity ?Alzheimer’s ?some birth surrenders There are most likely others however looking at this logically, how might it be alright for you to eat synthetic compounds and not anticipate some type of response in your body. Our bodies are delicwonderful machines. Any type of outside synthetic will undoubtedly cause aggravation in any event. (3)Some natural nourishments, including organic product, vegetables and milk, might be more nutritious than non-natural produce, as indicated by an examination by British researchers. Early outcomes from a ? 12m examination indicated that natural products of the soil contained up to 40% a greater number of cancer prevention agents than non-natural assortments, as per Professor Carlo Leifert at Newcastle University, who drives the EU-financed Quality Low Input Food venture. Bigger contrasts were found in milk, with natural assortments containing over 60% more cancer prevention agents and solid unsaturated fats, he said. Cancer prevention agent rich food is regularly advanced as more advantageous in light of the fact that in lab tests the mixes kill free radicals that are thought to add to maturing. (4) Ben Gold section of land says the Soil Associations analysis of the ongoing Food Standards Agency research on supplements isn't about natural food and that the emotive discourse for natural cultivating packs together differing and genuine worries about unchecked free enterprise in our food gracefully, actually, our contention with the FSA research is about whether it gives a reasonable and precise image of natural food. Gold section of land. In the first place, he said we were attempting to change the contention by saying that the significant issue with natural food isn't close to home medical advantages, yet rather advantage to the earth. More farmland natural life, high animal government assistance and lower contamination were not referenced in our own underlying reaction, yet were advanced unequivocally by the administration when the FSA propelled its report, and we rehashed it as the legislatures see, with which I concur. Second he contended that nonattendance of pesticides, no standard utilization of anti-infection agents on livestock and far less added substances permitted in natural food all convey medical advantages. Goldacre says that as these can't be estimated by the FSA research, referencing them is gamesmanship. These are genuine advantages, affirmed by other examination. The natural development speaks to a range of practices, mentalities, and ways of thinking. From one perspective are those natural experts who might not utilize compound composts or pesticides under any conditions. These makers hold unbendingly to their idealist theory. At the opposite finish of the range, natural ranchers embrace a progressively adaptable methodology. While endeavoring to keep away from the utilization of synthetic manures and pesticides, these experts don't preclude them totally. Rather, when totally fundamental, a few composts and furthermore herbicides are specifically and sparingly utilized as a second line of guard. By the by, these ranchers, as well, believe themselves to be natural ranchers [6]. For raising creatures, anti-microbials would not be allowed as development energizers yet would be allowed to counter contaminations. The standards license up to 20% of creature feed to be gotten from non-natural sources. This was done on the grounds that a few supplements, (for example, follow minerals) are not generally accessible naturally. Illumination, which can decrease or wipe out specific irritations, murder illness causing microscopic organisms, and delay food time span of usability, would be allowed during handling. Hereditary designing would likewise be passable. Increasingly Nutritious? Natural nourishments are positively not progressively nutritious The supplement substance of plants is resolved basically by heredity. Mineral substance might be influenced by the mineral substance of the dirt, yet this has no centrality in the general eating regimen. In the event that basic supplements are absent from the dirt, the plant won't develop. In the event that plants develop, that implies the fundamental supplements are available. Investigations directed for a long time have discovered no distinction in the supplement substance of naturally developed yields and those become under standard agrarian conditions. More secure? Numerous natural defenders recommend that their nourishments are more secure on the grounds that they have lower levels of pesticide deposits. Be that as it may, the pesticide levels in our food flexibly are not high. In certain circumstances, pesticides even decrease wellbeing dangers by forestalling the development of hurtful life forms, including molds that produce harmful substances . To ensure buyers, the FDA sets resistance levels in nourishments and behaviors visit showcase container contemplates wherein food sources from areas all through the United States are bought and investigated. Its 1997 tests found that about 60% of products of the soil had no recognizable pesticides and just around 1. 2% of residential and 1. 6% of imported nourishments had violative levels [13]. Its yearly Total Diet Study has consistently discovered that Americas dietary admissions are well inside universal and Environmental Protection Agency principles. Most examinations directed since the mid 1970s have discovered that the pesticide levels in nourishments assigned natural were like those that were definitely not. In 1997, Consumer Reports bought around a thousand pounds of tomatoes, peaches, green ringer peppers, and apples in five urban communities and tried them for in excess of 300 manufactured pesticides. Follows were recognized in 77% of ordinary nourishments and 25% of naturally marked nourishments, yet just one example of each surpassed as far as possible Pesticides can situate on the outside of food sources just as underneath the surface. The sum that washing can evacuate relies upon their area, the sum and temperature of the flush water, and whether cleanser is utilized. A great many people wash their products of the soil with plain Tastier? Naturally developed nourishments are not innately more delectable than routinely developed nourishments. Taste is affected by newness, which may rely upon how far the items must be dispatched from rancher to customer. What sorts of privately developed products of the soil are accessible differs from network to network. Regardless of whether they are naturally or customarily created is probably not going to have any effect. In the mid 1990s, Israeli analysts made 460 appraisals of 9 distinct products of the soil and no huge contrast in quality among natural and traditionally developed examples. The Consumer Reports study found no predictable contrasts in appearance, flavor, or surface. Better for the Environment? Numerous purchasers of natural nourishments accept that the additional cash they pay will eventually profit the earth by urging more ranchers to utilize natural strategies. Be that as it may, doing this can't have a lot of impact since natural horticulture is too wasteful to even consider meeting the universes food needs. Additionally, the isolating line among natural and customary agribusiness isn't sharp in light of the fact that different practices are not limited to either. For instance, natural ranchers tend not to utilize pesticides, however confronted with undermined loss of harvests, they may alter their perspective. In the event that specific examples of pesticide use cause more damage than anything else and there is an approach to cure the circumstance, the individuals worried about it can look for administrative arrangements. I dont accept that paying extra for food will profit anyone yet the individuals who sell it. This exploration appears there are benefits, said Dr Kirsten Brandt of Newcastle University, which drove the examination. The motivation behind why its such an ill defined situation is on the grounds that its very hard to quantify the medical advantage in any food, yet we can say that on the off chance that you eat 400g of products of the soil every day you would get 20 percent more supplements in natural food. Dwindle Melchett, strategy executive of the Soil Association, invited the new exploration. He stated: There is clear proof that a scope of natural nourishments contain progressively gainful supplements and nutrients and less of things known to have a negative wellbeing impact.

Be that as it may, the inquiry here is, if actually a specialist has a deep understanding of his field, for what reason does he need to lead tests and attempt various anti-microbials? Why doesnt he simply give the patient the ideal anti-microbials for his nourishment? Furthermore, the appropriate response is on the grounds that even a specialist isn't great and in this manner, needs to attempt various things in other to arrive at a resolution. Another model is that of a proofreader, crafted by an editorial manager is to ensure a book is fit to be distributed and offered to the general population; he evacuates what should be and puts what should be in a book. On the off chance that a book is taken to him, he checks the book and advances it to another editorial manager, the subsequent supervisor offers it to another proofreader which is the third editorial manager and the third supervisor offers it to the fourth individual who is the editor and afterward he edits and afterward at last to the central supervisor who at long last checks the book. Be that as it may, considerably after the book has been checked by very nearly five individuals, by the day's end, you despite everything discover you dont have the best work. Why? Since a manager alone can't check and edit a book. And furthermore no one is immaculate throughout everyday life. One thing that is consistent in life is change, which likewise influences the efficiency of specialists. Change is dynamic, things continue changing and individuals learn new things at each point throughout everyday life. For instance a specialist who has directed an exploration a year back wont hope to have a similar outcome on the off chance that he leads another examination on something very similar following a year. Since it may be conceivable that even at the hour of his past research, a certain something or different has changed and it will continue changing on the grounds that change is dynamic. A model is that of an architect who is supposed to be extremely inventive and a specialist in his field, if a vehicle is broken, he doesnt simply make sense of what the issue is by insignificant taking a gander at the vehicle, he needs to check the whole motor of the vehicle before recognizing what the issue is and how the issue happened yet significantly after he fixes the vehicle, it doesnt mean the vehicle wont confront additional issues later on, or regardless of whether the vehicle faces a similar issue later on, it doesnt mean its a similar expertise or technique he utilized in fixing the vehicle already that would be utilized whenever the issue happens. Why? Since change is dynamic, everything will undoubtedly change with time and there can be further developed methods of fixing it. Another factor that influences the efficiency of specialists is presumptuousness. In view of the accept individuals have in specialists, how they think specialists dont commit errors and how individuals think they are all-knowing, they will in general ignore the little necessities in their work. They become imprudent and commit a ton of errors. A case of a specialists remissness is an activity completed by a specialist. Who is a specialist A specialist is a specialist in his field which is to work patients however that doesnt mean his tasks are constantly fruitful and that he will undoubtedly commit errors. Much the same as on account of Dr. Nitin Aggarwal and his patient Gurcharan Singh which occurred in sat master Nagar on Sunday. Urologist Dr. Nitin being a specialist identified a tumor in his patients urinary bladder which he worked on the 31st walk. In any case, at that point, after the activity, the patient grumbled of fever and was again appeared to a similar specialist who determined him to have malignant growth and begun chemotherapy. Following a month his X-beam was done in an administration run medical clinic in Dhanaula and the X-beam indicated some scissors inside his mid-region. He was then alluded to a common emergency clinic where he was worked once more. For this situation despite the fact that the specialist was a specialist in his field, he neglected the easily overlooked details he should focus on d uring the activity and committed an extraordinary error which could have cost the patients life. On the off chance that somebody is arrogant or excessively brimming with himself, he will undoubtedly be indiscreet and in the event that he is thoughtless, at that point he will undoubtedly commit errors throughout everyday life. Specialists make an enormous thing out of what they have simply to get what they need from you. For instance, specialists have distinctive logical names for a specific infection, when a wiped out individual is taken to a specialist; he inspects the patient and gives the sustenance a logical name, if the patient happens to go to another specialist, the specialist will likewise analyze him and give the sickness an alternate name. This happens in light of the fact that, they additionally utilize their genuine beliefs and individuals dont question them since they believe they are specialists in their own field and that they can't commit any type of error. A few specialists utilize their genuine beliefs in camouflage of a very much done research and toward the day's end, they neglect to give supporting confirmations to back up what they state or write in a book. Indisputably, specialists can't generally be correct in light of the fact that no man is an island of information so nobody can know it all, nobody is great, and they will in general commit errors. Presumptuousness and lack of regard likewise influences their profitability which additionally drives them to committing bunches of errors. They make an exceptionally gigantic thing out of what they have simply to get what they need and change is dynamic which additionally influences their efficiency.

Who are Early Adopters and Why Do They Matter

Who are Early Adopters and Why Do They Matter When established marketers evaluate their most valued brand visibility tools, brand advocates, brand ambassadors, loyalists and fanatics are ranked very highly.But for new companies introducing new products and services, these groups are nowhere in sight, they have to be sought and nurtured from scratch.A review of some of the world’s most successful start-ups provides useful insights into the value of the first users of your product or service and their implication on future success.When Tinder co-founder and then VP for Marketing was faced with the challenge of building the app’s user base, she approached college sororities and fraternities and sold them the idea from university to university creating a network of seed users that propelled Tinder to the mainstream.When she left two years later in the December of 2014, she repeated the exact same thing when she started Bumble.Both these companies are now unicorns (privately held start-ups companies valued at over $1 billion whos e ‘lightning speed’ of growth is a statistical rarity).Joe Gebbia and Brian Chesky, the founders of Airbnb (Another Unicorn) discovered a vital ingredient of the app’s growth after a year or so of feeble uptake, by visiting their earliest seed users’ homes in New York City.They learned of important drawbacks to their service and upgraded their listings with monumental rewards.Similar narratives are reflected in the growth, in the popularity of Apple products, Fubu, Facebook, Reddit, Etsy, Uber, Salesforce and of course Facebook among others.They all have been able to harness the power of seed users/early adopters to propel their brands to staggering market success.WHO ARE EARLY ADOPTERS? In seeking to explain how a new idea, product or service gains momentum and over time is adopted by a population or a social system, social scientist Everett M. Rogers fronted the Diffusion of Innovation Theory in a book published in 1962.His research and subsequent studies show that adoptio n of a new idea or product does not happen simultaneously in a social system, in that some people are quicker at accepting innovations than others.The theory establishes five adopter categories; Innovators, early adopters, early majority, late majority and laggards.Innovators (2.5%) are the first people who want to try an innovation. They are very willing to take risks, usually have the highest social class, have great financial lucidity, are often the first to develop new ideas, very social and have closest contact to scientific sources and interaction with other innovators.Due to their high risk tolerance they do adopt technologies that may ultimately fail but are cushioned by their high financial resources.Early Adopters (13.5%) are the second fastest category to adopt an innovation. They have the highest degrees of opinion leadership on many fronts and are considered by many as ‘the individual to check with’ before adopting a new idea.Unlike innovators who are cosmopolites, Early Adopters are not too far ahead of the average individual in innovativeness and as such serve as role models in the social system.To maintain their central role in social communication system and the esteem of their peers, they realise they have to make more judicious choices in the adoption than innovators.They are nevertheless younger, of higher social status, have advanced education and more socially forward than late adopters. Rogers argues that Early Adopters help trigger the critical mass by decreasing uncertainty about a new idea.Adoption lifecycle for new technologies. The brown line shows a product’s market share growth over time, while the other line shows how the market share is distributed among different types of buyers.Early Majority (34%) are a category of individuals who make the decision to adopt an innovation after a relatively longer period than innovators and Early Adopters. They are theorised to be more deliberative, typically seeking evidence that an inn ovation works before they are willing to adopt it.They usually have above-average social status, they have frequent interactions with early adopters but are rarely in a position to lead opinions within the social system. The position between the very early and the relatively late is an important link in the diffusion process.Late Majority (34%) make the decision to adopt an innovation after the average member of the social system after approaching the new idea with a heightened sense of caution and scepticism.Adoption by this category is theorised to happen, in part, as an economic necessity and as a result of greater peer pressure. They are of lower socio-economic status, have very little financial lucidity and very little opinion leadership.Laggards (16%) are the last to adopt an innovation, they have near-zero opinion leadership, primarily interact with other individuals holding relatively traditional values and typically older. They are averse to change with their point of refer ence being the past.UNDERSTANDING EARLY ADOPTERSGiven how crucial the early stages of a business are on long-term success and the potency of the thought leadership that early adopters wield in triggering a knock-on effect in the product adoption process, it is important to dive deep into their psychographic characteristics.A slow start for a startup has almost always been a strong indicator of a business that might not reach the growth stage in the product life cycle, while a great start is often indicative of a safe product lifespan.This is true of the technology startups reviewed earlier as it is of box office releases and music album launches.Early adopters give you the first impression of the market, they are effectively the metric for how strong your start has been.Taking off from their theorised apparent position of privilege in society, early adopters seek and need to be first.As a general trait, Rogers observes that earlier adopters seek information about innovations more ac tively than do later adopters.They would want to credit for popularising a new idea, app or service to raise their social profile and maintain the respect of their peers.A plausible explanation of early adopters’ restless pursuit of what’s new was offered by author-adventurer Craig Childs on the Living on Earth show while discussing his 2018 book Atlas of a Lost World: Travels in Ice Age America.His research identifies a distinctive trait in the less risk averse people â€" a genetic marker called D4 (a dopamine receptor) â€" those with more D4 tended to be less cautious and adventuresome, settling much further from the Arctic up to South America.Those with lower D4 levels tended to settle earlier. ‘There is a genetic drive to go further,’ Childs suggests.Dopamine is a neurotransmitter chemical whose reputation as the ‘feel-good hormone’ is due to its association with the brain’s reward and pleasure centre.Marketers have for ages deployed dopamine-triggered pleasure in witty adverts to create memorable and euphoric associations with their brands.Early Adopters, similarly ‘feel good’ whenever faced with a prospect of learning and leading in the adoption of a new technology â€" their dopamine system is activated, triggering psychological reward signals and feelings of pleasure and motivation as opposed to fear of failure that sceptical later adopters may harbour.It thus follows that early adopters, while motivated by career, family and entertainment like regular consumer the psychological motivations that set them apart from the general population as proposed by Forrester’s 2009 Research and Ad Age Insights are information, novelty and status.They do not just buy something first without conducting significantly more research than the average consumer mitigating the inherent risks of arguably untested products.While they might be emotional impulse buyers, they are rational researchers first.In their novelty-seeking mode, early adopters are cons tantly looking for what’s new as part of a personal entertainment goal which also feeds off the probably strongest psychological motivation â€" status.We all know the first person to blog about the iPhone X’s notch or post on Facebook about Google Pixel’s incredible image quality early in its launch.WHY YOU SHOULD BE CONCERNED ABOUT EARLY ADOPTERSBeing your very first users, they give you a glimpse into how the market responds to your product.They are aware that your product is in its infant stages and by purchasing it, the financial risk involved is well known to them hence the need to conduct extensive research.They are loud people, thought leaders who will blog, post on Facebook and Tweet about their experience with your product. If the product delivers value it will receive praise from them and with it recommendations to their social networks composed of later adopters.If they reject your product for whatever reason, your brand is bound to suffer significantly.You will hav e significantly lost your biggest converting marketing tool.As illustrated in the bell-curve of technology adoption above, research shows that for start-ups the leap from Early Adopters to Early Majority is the toughest to make of the entire life cycle.Your product must survive the rigors of early adopter testing to overcome the initial scepticism of the deliberative early majority if it is to gain mainstream marketplace acceptance.Early adopters are exceptionally good at influencing others based on their credibility that is anchored on their authority, knowledge, position or relationship with the target audience which is a part of their often huge fan following.WHAT CAN EARLY ADOPTERS DO FOR YOU?After a very high-profile startup failure, American Entrepreneur and Author of the book, The Lean Startup, Eric Reis co-founded the virtual reality metaverse IMVU in just six months and went on to experiment with early adopter testing of the then highly buggy version.Ries says by including early adopters from the early stages of product development, the start-up was able to produce a better engineered product and the transition to mainstream acceptance, or what Geoffrey Moore calls ‘crossing the chasm’ was seamless.“[They]… were people buying from us not the product as existed at that time, but the vision of the product that we thought it would be… Visionary customers are often smarter and more visionary than the companies that serve them.And so by being in constant dialogue with them from almost day one of our company’s life, we were able to learn a lot of important lessons about what the product needed to become in order to eventually achieve mainstream success,” Reis says in a 2009 presentation at Stanford University.Some of the benefits to be gained by working with early adopters include:Product-Market FitAs in the IMVU product development journey, early adopters can make it easier for you to achieve a product-market fit early in the product life cyc le and save you the risk of rejection in the mainstream market.As already established, early adopters do not necessarily get on board your idea because it is perfect and exhaustively engineered. They care about the aspirational value it offers, functionality and getting a competitive edge in the social system.In The lean Startup, Eric Reis offers examples of the scramble for Apple’s original iPhone by early adopters even if it lacked basic features like 3G Internet speed, as well as the praises they sang for Google’s initial search engine years before it could topple Yahoo to be king of web search.They are happy with the 80 percent that is perfect and are willing to contribute to improving the remaining 20 percent.They will provide you with useful feedback that will be monumental in the rethinking of problematic product features as Joe Gebbia and Brian Chesky found in the early stages of Airbnb.They care about the problem as long as they have seen the core value and resonate wit h the product’s vision.Predictive ValueEarly adopters literally get the party started for a product at its launch or upgrade phase and can be a reliable measure of whether the company’s purported solution to an existing problem has an underlying demand in the market or a boardroom myth.Apple’s every upgrade of the iPhone and yearly introduction of a new Macbook is one demonstration of the predictive potential of early adopters.The queues at its global retail stores on the launch week are indicative of the product’s longer-term market performance.The same goes for reports of first week ticket sales or album release purchases.A Pointer to Growth ChannelsAcquiring your first users can be a crucial factor in discovering the channels to focus on in order to achieve growth.Once the product-market fit has been established, you should begin to have a better picture of the ideal channel(s) that maximise growth for your new product.This is what former Hubspot VP for Growth and Reforge founder, Brian Balfour calls Product/Channel fit in his conviction that PMF alone will not propel your product to runaway profitability.He argues that products are built to fit into channels for the simple reason that channels such as Facebook, Google or email clients do not mould into products but rather define their own rules that the product has to map into.Each product is theorised to have its optimal distribution channel and early adopters are your best at identifying it before scaling distribution.Product EvangelismThis one is more obvious. Once your early adopters have experience the product or service and they love it there is a huge chance they will freely attempt to convince others to try it.It is distinct from influencer marketing where, while both could be public figures commanding a significant following, influencers charge relatively cheap fees to post about the product and their endorsements may be viewed with suspicion while evangelists recommend the product out of pure belief.Once your product achieves the acceptance of early adopters, two cultural phenomena that have arisen from today’s interconnected world should work in your favour.First is the share effect where word of mouth on social networking channels can organically improve your brand reach and work double-duty as endorsement.The second is FOMO â€" Fear of Missing Out â€" which corresponds with the unique position that early adopters occupy in the innovation adoption life cycle.This will potentially create the bandwagon effect.This MIT study on Bitcoin adoption illustrates how early adopters influence the decisions of a majority of consumers in a social system.HOW DO YOU GET YOUR EARLY ADOPTERS?Like Eric Reis did when launching IMVU, a user-gathering strategy is the first thing you must come up with after your ground-breaking idea.It is even more important to ask yourself who your early adopters are more than who the target audience is â€" they are your ultimate target at this stag e and from there will lead the way as discussed above.To identify your Early Adopters you have to consider three inherent aspects of this group of adopters; they have a problem they seek to solve, they are well aware of what the problem is and are actively seeking a solution for it.Paul Friederichsen, founder of The Blake Project, advises that the best success in attracting them is by presenting your product or idea as the ultimate solution to their problem in addition to factoring their psychological motivations.But where do you find them? Below are some places you can find early adopters.CommunitiesWeb forums, slack channels and Subreddits are some of the most effective platforms to begin engaging your potential first users.You want to become a power user so that you can use this credibility to advertise your idea, get in touch with other power users who can be your product advocates and to also get exposed to your target audience and acquainted with the problem they are trying to solve.Finding the appropriate community can be as easy as a Google search but becoming a power user takes some significant work and patience.Social NetworksUnlike the niche communities above, for social network such Facebook, Instagram and Twitter, you have to find the sub-groups and address them individually.Facebook and LinkedIn Groups are one example where you can succeed in finding your first users.You have to abide by a set of rules and contribute to discussions and help other users while documenting their needs and frustrations that your innovation can solve and then time your pitch once you have acquired some appreciable level of respect.You can also follow hashtags to identify topics and most knowledgeable users to approach appropriately.An analysis of influencers’ followership using tools like Followerwonk and Facebook Insights could also point you to you first users.Blogging at your own site (leveraging already-built audience), guest blogging and direct outreach through emails and messengers like WhatsApp or a soft launch as in the case of Dropbox on Digg could also be effective options based on the product type.HOW DO YOU TURN THEM INTO BRAND ASSETS?Once your first users begin testing your product you need to start a conversation; make your forum or email address easily identifiable, create a hashtag you can communicate through in real time, make the comment section on your open and ask for feedback regularly making sure they are aware that you are always listening for feedback and leave easily noticeable appreciative notes.Remember to also share your success with them. Below are some tips on how to turn early adopters into brand assets:Treat your early adopters as VIPs: Early adopters are your most valued customers given the fact that they have taken the risk of purchasing your product which might be flawed and could become cheaper in the longer-term.They are to a large extent your team members and such are entitled to some form of reward even i n the simplest form of taking extra time to answer their queries and educate them about the novel product you are introducing.One of the best ways to reward your early adopters for the risk they are taking is by giving them access to pre-releases. You will be giving them exclusive access to a new feature or upgrade as an appreciation for what is effectively working with you.Another approach that works well for SaaS products is the freemium model   where you reduce the amount of risk your early adopters are taking that, which could in turn help spread word further or in fact, get you your very first users.You should also consider setting up a referral program where an existing user is rewarded for referring a new user effectively increasing the user base for small incentives.Referral marketing has been proven to be successful for a range of products from electric car maker Tesla to UK mobile telephone operator GiffGaff that offers double incentives for both referrer and the new user. It has been particularly effective for mobile apps such as Dropbox and Uber. For early adopters, referrals make sense as they extend their influence in the social system as pioneers giving them ‘feel-good’ effect.While Early Adopters can serve your startup or new idea immensely, they should not substitute good product design.Clarity of communication, in-depth research, reflexivity and tolerance to criticism will complement the imminent gains to your business.WRAPPING UPEarly adopters are critical for the success of any new product or service.They take the risk of testing a product to see how it works, and are responsible for eliminating some of the inhibitions the rest of the population might have about adopting your new product.They also provide you with an opportunity to test and improve your product before it gets to the mass market.As such, it is important to nurture your product’s early adopters and work with them to drive mass adoption of your product.

Effect of Acetaminophen Sulfate on the Growth of Neurite in PC 12 Cells under Various Concentrations (Lab Report Sample) Content: Firstname LastnameInstructors NameCourse NumberDateEffect of Acetaminophen Sulfate on the Growth of Neurite in PC 12 Cells under Various Concentrations SummaryBackground: Neurite outgrowth is the process by which the nerve cells undergo a development process to produce new projects in neuron cells which can result in increased activities of the neurons in the brain. Acetaminophen sulfate is an inactive metabolite of acetaminophen (paracetamol), a low therapeutic drug which is widely used to control pain and reduce fever. Materials and Methods: The experiment presumes that different concentrations of acetaminophen sulfate can influence the neurite outgrowth in PC 12 cells lines derived from the  HYPERLINK "https://en.wikipedia.org/wiki/Pheochromocytoma" \o "Pheochromocytoma"
Pheochromocytoma in the medulla of a rat. Different concentrations of acetaminophen sulfate were mixed with NGF-induced PC12 cells to test whether or not acetaminophen sulfate would affect neur ites outgrowth. The test also analyzed the rate of the neurite outgrowth among the different concentration of acetaminophen sulfate. Results: With acetaminophen sulfate treatment at varying concentrations, there was no effect on the growth of neurites on the NGF primed PC12 cells. Conclusion: The results are similar to previous observations from in-vitro studies which concluded that acetaminophen sulfate does not affect neurite outgrowth in PC12 cells. IntroductionNeurons are the basic functional units of the nervous system that receive and communicate information in the brain by transmitting electrical impulses (signals) from one part of the brain to another, the sensory organs to the spinal cord and from the spinal cord to the receptor organs. There are over 100 billion nerve cells in the brain which communicate with each other in an organized manner to form a neuron network (Byrne np). A single neuron is made up of three parts, the dendrite, the axon and the cell body. The dendri tes receive input information from sensory organs and other neurons. The cell body interprets the information and sends an output signal through the axon to the effector organs and other neurons (Cherry np). Electrical impulses from the axon stimulate the release of specialized chemical signals called neurotransmitters such as the endorphins, epinephrine, and acetylcholine. These neurotransmitters affect several physiological functions such metabolism, learning, sleep, appetite and movement. Neurons can undergo a development process known as neurite outgrowth to produce new projections which can mature into dendrites or axons. The development of the neurites increases the neuron network and the activities of the nervous system in the brain. The inhibition of the neurite outgrowth can result in impaired cognitive functions (Meldoles np). The neurite outgrowth can be stimulated by several factors such as nerve growth factors and neurotrophins. Medications and pharmacological ingredien ts can also affect neurite outgrowth. Understanding the physiology and mechanism of neurite outgrowth can help to shed more light on the biology of some neurodegenerative diseases. Scientists apply several special techniques to grow neuron cells using specialized cell lines such the PC12 cells, stimulate neurite growth using neurogenic compounds and monitor the behavior of the growing neurites (Millecamps Jean-Pierre np).PC 12 cells are used to assess how varying concentration so of acetaminophen sulfate affects the outgrowth of neurites. PC 12 cells are cell lines that are extracted from the  HYPERLINK "https://en.wikipedia.org/wiki/Pheochromocytoma" \o "Pheochromocytoma"
pheochromocytoma of the rat.  HYPERLINK "https://en.wikipedia.org/wiki/Pheochromocytoma" \o "Pheochromocytoma"
Pheochromocytoma is a malignant tumor in the medulla of the adrenal glands or the chromaffin tissue which produces and stores a lot of catecholamines such as norepinephrine and epinephrine. PC12 cells are small and irregular scattered cells which grow in suspension or liquid media (Wang et al. 62). The PC12 cells originate from the neural crest which has both the primitive nerve cells and eosinophilic cells. The embryonic nature of the PC12 cells means that they can be cultured indefinitely and can readily differentiate into cells that share the same properties as the nerve cells such as the release of neurotransmitters (Mingorance-Le, Alma Timothy np). Immature and undifferentiated PC12 cells have no neurites and have a little responsive capacity to neurotransmitters. When exposed to nerve growth factor (NGF), the PC12 cells stop the replication process and start to differentiate into irregular neuron-like cells with many long projections similar to those seen in neurites. NGF is essential in regulating the growth and differentiation of the neurons, and the performance of the central and peripheral nerve cells. The differentiated PC12 cells can be excited by electrical i mpulses and respond to neurotransmitters (Oliveira et al. 78).Because of the similarities between the differentiated PC12 cells and the nerve cells, PC12 cells have extensive application in the study neurological diseases by creating artificial tissues of the nervous, which can be used to study neurodegenerative and neurochemicals. PC12 cells are preferred for neurological studies such as the NGF-induced neurite formation over other cells lines because of their unique abilities to exit the cell division cycle and differentiate into other cells types when exposed to certain chemicals. Unlike the chromaffin cell lines, PC12 cell lines can also proliferate easily in growth media and release hormones such as catecholamines upon stimulation (Malagelada Lloyd 376).In cell culture, the PC12 cell lines are grown in suspension media which contains amino acids, serum, glucose, vitamins, and antibiotics such as penicillin to prevent the contamination of the cell culture by bacteria and fungi. The media also constrains a red indicator which turns to yellow when the cells are alive and purple when the cells are dead. Laminin is a glycoprotein that forms part of the extracellular matrix in human and animals. The extracellular matrix is located outside the cells and is important in providing support and attachment to the cells in the tissue and organs. The structure of laminin is vital to its functions. Laminin is a cross-linked molecule that is made up of a combination of alpha, beta and gamma chains located on three short extensions and one long extension (Aumailley 48). The extensions on the laminin are essential in cell adhesion. The short extensions of the laminin molecules allow them to bind to each other to form long sheets while the long extension can attach to cells and anchor them to the plasma membrane. Currently, there are more than 16 laminin molecules which are important in gluing cells to the connective tissues and promote normal cellular functions (Domogatsk aya, Sergey Karl np).The function of laminin in the body is to facilitate cellular attachment and enhance motility, proliferation, and differentiation of cells. Laminin binds to cell membranes using the integrin receptors and other glycoprotein molecules such as dystroglycan (Yurchenco 5-7). This ensures the survival of tissues and that the shape of the cells and the structure of the tissues are maintained efficiently. Laminin glycoprotein is secreted outside the cells and incorporated into the extracellular matrix of the cells. Laminin is used to enhance cell cultures and provide a conducive environment for the neuron cells, cardiomyocytes and endothelial cells to adhere, proliferate and differentiate in-vitro. Commercially available laminin are extracted from mouse sarcoma (Laminin-111) and human placenta (laminin-211, 411 or 511). Laminin-111 serves as a substrate for the growth of nerve cells in the body and cell cultures. In vitro cells, studies have demonstrated the importanc e of laminin in enhancing cell adhesion, neurite growth and survival of cells under stress (Miyazaki et al. 7).Impaired laminin can result in the improper formation of tissues and organs such as the brain, the kidney, and the skin, resulting in muscular dystrophy and nephrotic syndrome. Some laminin has also been linked to the spread and invasive nature of malignant cancers. A recent human study has reported that over-expression of the laminin-511 was critical in the dissemination and invasion of tissue in patients with advanced breast carcinoma. Therefore, by targeting laminin-511, scientists can develop therapeutic strategies in cancer patients (Pouliot Nicole 142-143). Acetaminophen sulfate is a pharmaceutical metabolite of acetaminophen (paracetamol). Acetaminophen is commonly used medicine for the management of pain and fever. It is a commonly prescribe over the shelf medication in adults and children and has a low therapeutic index. Acetaminophen inhibits the production of pr ostaglandins in the tissues during injuries, by inhibiting the activities of cyclooxygenase 2 (COX) enzymes (Hinz Kay 20). Prostaglandins are a group of lipid hormones that are involved in the healing processes, resulting in inflammation, pain, and fever. By reducing the synthesis of prostaglandins, the pain threshold in the body and the temperature control center are regulated, thus reducing pain and fever (Ricciotti Garret 987). In Humans, mice, and rats, acetaminophen is metabolized in the liver and converted to inactive substances which are eliminated from the body through the urine. In the liver, the cytochrome P450 enzyme system metabolizes a small concentration of acetaminophen. Acetaminophen is oxidized to produce a reactive and toxic intermediary metabolite N-acetyl-p-benzoquinone imine (NAPQI). The toxic acetaminophen compound combines with the sulfhydryl group and is converted t...

Dna, Clues And The Cheetah s Speed And Hurdles - 1235 Words

â€Å"In DNA, Clues to the Cheetah’s Speed and Hurdles,† by Barbara S. Moffet is an article published in the New York Times Science. This article fascinated me when I first read it because the topic not only perfectly aligned with what we have covered in class so far, but the story is the epitome of the power of genetics, genomic diversity, mutations, and natural selection playing in the ecosystem. In the article, Moffet introduces a study done by scientists at the Theodosius Dobzhansky Center for Genome Bioinformatics at St. Peterburg State University In Russia collaborated with BGI-Shenzhen in China and the Cheetah Conservation Fund. It was to analyze the entire genome of the cheetah by using blood samples from a cheetah known as Chewbaaka and six other cheetahs from Namibia and East Africa. Interestingly, the complete sequencing of the genome of cheetahs uncovered many interesting facts about cheetahs, including their impoverished genetic diversity, history of their population bottlenecks, and many mutations that led to their unique physiology and characteristics as one of the fastest animals existing in the current ecosystem. Genetic diversity in an animal is the total number of genetic characteristics in the genetic makeup of a species, and it allows the population to adapt to the changing environment. Therefore, the more variation an animal contains, the higher chance it has the alleles that enable them to cope more successfully in the nature. However, through the genome

Augusto Gutierrez ENGLISH 1303 Instructor Zachary Turpin October 20, 2014 What is Post Traumatic Stress (PTS)? What are the effects and why should it not be considered a disorder? What is Post traumatic Stress Disorder or more commonly known as PTSD? It is unfortunately an affliction that has been generalized to a veteran issue as a negative side effect of enlistment and deployment to Iraq or Afghanistan, it is the â€Å"Agent Orange† of my generation. If you are unaware â€Å"Agent Orange† was a chemical that the military used in Vietnam as a chemical defoliant to ensure leaves would fall of the plants effectively removing forms of cover the Viet Cong troops used, as well as crops that were given in support of them. It has now been linked to causing various types of cancers and other medical issues not previously expected, this of course added more stigma to plague veterans of a long hated war. The biggest difference between Vietnam and now is that we are a volunteer force not like Vietnam which was a draft opposed by many, which has led to an apathy to fall on the American public. The origins of this affliction older than many realize as it dates back to the Bronze Age, Greek historian Herodotus wrote his account at the battle of Marathon 490 B.C.E. about an Athenian soldier who became blind â€Å"without blow of sword or dart†.

The Lord Of The Rings - 1698 Words

People are always looking for good ways to entertain themselves. Over the past few hundred years, several art forms have become a commonplace in society, such as plays, music, drawings, books, and, more recently, movies. Books and movies are two that have stomped their way into society with no remorse. They have been great ways to express people’s opinions, make social statements, and most importantly, entertain audiences. Both of these have had a profound effect on the world, whether it be through changing a way of life or just by making time pass for a few hours. Certain books and movies have played great roles in the world and had many influences. The Lord of the Rings has had a massively positive effect on both literature and film. Its creation has led to many positives and in doing so has become one of the most influential stories ever created. It has also led to some major impacts outside of literature and the film industry as well. Fantasy books have been around for a long time; however, the fantasy that people think of today has only been around for close to a century. Modern fantasy can very much be credited to J.R.R. Tolkien and his Lord of the Rings book series. According to author Katie Behrens’ article â€Å"Myth, Fairy Tales, Children: A Brief History of Fantasy†, The Lord of the Rings has had a profound effect on shaping fantasy into what it is today.

The Age Of The Reformation - 2258 Words

It is a well known fact that the Age of the Reformation was one of the significant movements in Western Christianity. The Protestant Reformation was a turning point in religion. Martin Luther, John Calvin etc. were reformists that allowed the Reformation to occur. However, before them there were other efforts that had been done for the reformation by Peter Waldo, John Wycliffe, Jan Hus, and so forth. According to (Bainton pg. 12) â€Å"the 16th century was an age of faith. It was even more an age of faith than the preceding period. For a parallel, one must go back several hundred years to the years to the days of the First Crusade or even to the founding of the Inquisition.

In that year he experienced some kind of conversion after having been struck by a bolt of lightning. He cried out, Help, St. Anne, I will become a monk. He was struck by the hand of God and felt that God was in everything. He felt doubt within himself – he simply could not reconcile his faith with his worldly ambitions. And so, Luther was plagued by an overwhelming sense of guilt, fear and terror. To relieve his anxiety he joined the Order of the Hermits of St. Augustine. There he would be shielded from worldly distractions. There he would find the true path to heaven. He fasted, prayed and scourged himself relentlessly. But he still felt doubts. One day, as he sat in his cell, he threw his Bible on the table and pointed at a passage at random. The passage was from the Epistles of St. Paul: For the justice of God is revealed from faith to faith in that it is written, for the just shall live by faith.

Reliability and Validity Matrix Free Essays

TEST of Reliability | Application and APPROPRIATENESS| Strengths| Weaknesses| Internal Consistency| This measure of reliability is appropriate when trying to determine the difference in reliability from shortening or lengthening a test (Cohen Swerdlik, 2010). Here I am specifically referring to the Spearman-Brown formula being used to determine internal consistency. A researcher could also use other measures of internal consistency meant for heterogeneous test items, such as Inter-item consistency. We will write a custom essay sample on Reliability and Validity Matrix or any similar topic only for you Order Now The reliability of a test increases with an increase in the number of test items. One of the strengths of the Spearman-Brown Formula is that is can determine how much more or less reliable a test is as a researcher lengthens or shortens the test. This measure can also work in reverse and tell a researcher how many items they need to add to reach a certain reliability coefficient. | The problem with the use of the Spearman-Brown formula to determine internal consistency is that it is only affective with homogenous test items, that is items that are the same difficulty and length. Also, tests of reliability are higher for whole-test vs. half-test applications of the formula, which means that lengthier tests work better with this instrument. | Split-half| The split-half form of measuring reliability entails creating two halves in the same test that can be compared in the same manner as the parallel form of reliability testing uses. This type of measurement is appropriate when using odd-even reliability or random assignment splits, but is most applicable when designing mini-parallel forms of the same test. In this instance, each half is, â€Å"†¦as nearly equal as humanly possible—in format, stylistic, statistical, and related aspects† (Cohen Swerdlik, 2010, p. 145). | The strength of this kind of measure is that it is less time-consuming and less cumbersome for test-takers than the parallel form, but is also a good measure of internal consistency. This type of measurement also help keep in check intermediary variables that might introduce error variance into the analysis, since the both parallel portions of the test are taken at once. However, there are several intermediary variables that are enhanced by this form of measuring reliability: fatigue that is felt during the second part of the test but not the first and variance in the difficulty or content of the items in the first half vs. the second half. It is also not advised to simply split a test down the middle. The different halves should have the same content and difficulty of question for the measure of reli ability to be accurate. Test/retest| This type of test is applicable when the construct being measured is relatively stable over time, but is inappropriate for constructs that are not stable over time (Cohen Swerdlik, 2010). This is because test/retest reliability is based on taking the same test, with the same people, at two different times. If the construct being measured is purported to change over time, then the scores of the test would vary because of true variance, rather than error variance—which is the basis of reliability, the latter that is. An example of this principle might be an achievement test measuring grammatical skills. If the test-taker undergoes a series of lessons on grammar between the first test and the second test, then the test will show variance, but not due to error but due to the intermediary variable of education. Test/retest reliability would be inappropriate in this situation. | The strength of this measurement of reliability are in tests that, â€Å"†¦employ outcome measures such as reaction time or perceptual judgment† (Cohen Swerdlik, 2010, p. 143). This is because these types of psychometric traits do not vary greatly over time and are not sensitive to many types of intervening variable. The weakness of test/retest reliability is, of course, that the underlying constructs being tested can change over time, and therefore lower the test/retest reliability due to true variance rather than error variance. In this case, the overall reliability of a test might be seen as lower even though the actual measurement of the construct is stable (it is just that the construct itself varies). | Parallel and alternate forms| Both parallel and alternative forms of test reliability utilize multiple instances of the same test items at two different times with the same participants (Cohen Swerdlik, 2010). These types of measures of reliability would be most appropriate with tests that measure traits that are stable over a long period of time and inappropriate when measuring finite emotional states or anxiety levels. | The strength of this measure of reliability is that it measures the core construct through several variances of the same test item. If equivalent scores are found on multiple forms of the same test item, then the reliability of the test will go up. Moreover, there are ways to perform this type of reliability analysis without having the test-taker undergo multiple examinations: internal onsistency estimate of reliability. This type of analysis would save time and money. | Designing these types of measures are time-consuming, expensive, and tiresome for the test-taker who has to take variations of the same test items over and over again. Also, these forms of testing reliability are not dependable for measuring constructs that change over time, such as anxiety levels. Anoth er weakness is that if the tests are taken some time apart, then intervening variables might have an effect on the scores, thereby increasing error variance. Test of Validity| Application and APPROPRIATENESS| Strengths| Weaknesses| Face validity| Face validity is a description of the subjective perception of the test-taker of the test’s validity (Cohen Swerdlik, 2010). This measure is not so much a quantification of the test’s actual validity, but a measure of the test-taker’s perception of the test’s validity. Face validity is most appropriate when measuring the test-takers confidence that a test measures what it purports to measure. The strength of face validity is that if the test-taker has confidence in the validity of test, then they are more likely to take the test, and further the test user is more likely to administer the test. Without face validity, the test might be perfectly valid, but it is not administered or taken properly because the user/ taker does not have confidence in the test. | The weakness of face validity is that it might not measure actual validity. A test can appear to be valid to the user/taker while also being completely invalid for the construct/time/place of the test. A good example might be the inkblot test. Psychologists that adhere to the psychodynamic perspective of psychopathology would say that the test is perfectly valid for determining personality characteristics, but the test taker might not understanding how the test applies to personality development, thereby undermining the face validity of the test. | Content validity| Measures of content validity are most useful in situations a test designer is trying to create test items that match the content of the material being tested (Cohen Swerdlik, 2010). For instance, a final course exam should test the content area that the course covered. Further, this measure might not be applicable in situations where the skills that the test designer are looking for in the applicant are not currently part of the skill-set of the already employed, such as in cases of new positions. | One of the strengths of content validity is that it can used to work backwards from job responsibilities to job applicant requirements. First, the test designer would examine veteran workers perform their job, and then design an application process that looks for these qualities in a potential employee. The items that are judge essential for the job are the ones that are most advantageous for the applicant to possess. | The downfall of content validity is that the perspective of the material being covered is culturally and chronologically subjective, meaning that the questions can have different answers in different areas of the world or at different times. Therefore, the test items must be culturally and chronologically accurate for the test-takers for content validity to be used. | Criterion related| I know this is personal opinion, but I think that criterion-related validity is the most powerful of all of the methods of verifying validity—especially concurrent validity. This type of validity is used to verify that the criterion that the test score purports to represent is actually in the sample of individuals being tested (Cohen Swerdlik, 2010). For instance, a group of people who have already been diagnosed with schizophrenia could be tested using a new instruments and if they all score high on the test for schizophrenia, then the test can be said to have acceptable validity. | One of the strengths of criterion-related validity is that it is a very powerful measure of the actual validity of a test score. This type of validity uses methods external to the test itself to verify that the test covers the subject matter and criterion that it purports to cover. This fact alone makes this measure the most objective and verifiable of the measures of validity. A weakness of content validity is that criterion contaminations can occur, which is when the same predictor measure and criterion measure are used. As an example, if the diagnosis of a mental disorder by a panel of diagnosticians is used both as the test criterion and the measure of test validity. | Construct| Construct validity is the umbrella under which all of the other sub -types of validity fall (Cohen Swerdlik, 2010). Construct validity is appropriate to use in cases where a test is trying to measure some underlying construct, such as intelligence or anxiety. I suppose this measure of validity might not be appropriate in situations where there is not one clear construct that is being measured, such as generalized achievement tests. | One of the main strengths of construct validity is that the procedures used to verify underlying constructs follow the edicts of the scientific method. A hypothesis is formulated, predicting that if someone possesses in great quantity the construct of intelligences—as verified through other measures—then they will score high on a test purporting to measure intelligence. In this way, a predictions is made based on scientific facts and then the test is used to determine if the prediction holds true. If it does not, then the test items, predictions, or underlying construct might need to be revised. | The downfall of this measure of validity is that if there is not one clear construct or if the construct is vaguely defined, then the validity of the test score is not measurable. So, the validity of the test rests on the underlying construct definition and specificity. | How to cite Reliability and Validity Matrix, Papers
