Synthes Case - 727 Words
Synthes Case Study Team S Santiago Sanchez Villalba Bharat Pawar Morris Li Jose Llanos Tiia Paananen What are the different threats to the sustainability of Synthes` competitive advantage? Synthes has several threats to consider in the near and upcoming future. The first threat we can talk about is with regards to imitation. Imitation is a big deal in the internal fixation device industry. Synthes has become the leader in this market due to several competitive advantages, for example the affiliation with AO, which surgeons take as a sign of confidence. These advantages have been able to sustain them with huge market share and very high sales during the last 20 years. They have also created other competitive advantages withinâ⬠¦show more contentâ⬠¦The threat level is still low because the first trial of bioresorbable failed and the second generation has not yet fully convinced surgeons. But most doctors seem open to the idea or already use some of the bioresorbable derivatives to substitute some of Synthes` products today. The difference from the first generation bioresorbable products to the second one improved drastically and the third generation could eventua lly be almost as effective as todayââ¬â¢s solutions. If Synthes is not fully prepared there could be a very big threat to the company not only in sales but also reputation because they are known for being the top dog and always offering the newest products for internal fixation. A company with a similar strategy (affiliation to AO, good sales reps, high quality product) could not only imitate but also substitute if the product part were to be able to be effective and accepted by doctors. Although there are threats in a competitive industry such as this one, we believe that Synthes has enough actual and probable competitive advantages to sustain throughout time as a leader in the internal fixation industry. When we discuss the S-Curve for Synthes, we could see that bioresorbable technology is slow and improving poorly because it is not understood quite well. If anybody gets it right we could see the acceleration process and this is where Synthes would be highlyShow MoreRelatedSyn thes Analysis Essay3120 Words à |à 13 PagesCASE ANALYSIS Synthes 1.

Convertibility and its problems in the 1999/2001 period 1. 1 Previous Devaluation Process in Argentina Three main large devaluation episodes prior to the monetary reform of 1991 can be identified in the graph: 1975-1976 (the so called ââ¬Å"Rodrigazoâ⬠), 1982-1984 (the ââ¬Å"Post Malvinas Warâ⬠monetary collapse) and 1989-1990 (the ââ¬Å"Hyperinflationâ⠬ ). (http://www. cavallo. om. ar/wp-content/uploads/2012/05/Devaluation-and-Inflation-. pdf) 2. First moments of devaluation Basically you can distinguish three half-year periods centered on the political and financial collapse at the end of 2001 namely: Precollapse (to September, 2001); Collapse (October 2001 to March 2002); and Depression (from April 2002). This section will focus on the end of the Collapse and the beginning and ongoing Depression. As earlier mentioned Argentina applied a currency board at the beginning of the 90ââ¬â¢s which pegged the peso to the dollar and formed a fixed exchange rate. After the Crisis of Argentina had begun they had to decide how they can diminish the effect of the emerging depression. In December 2001 Argentina officially defaulted and in February 2002, the value of the pesos was almost half of the dollar, Eduardo Duhalde became president. He had to manage a country which was in a really bad condition. Different economists favored different strategies to stabilize the economy. Some favored a ââ¬Å"pesification followed by a free-floating regimeâ⬠and others ââ¬Å"devaluation and subsequent dollarizationâ⬠. Both of those possibilities are heavily discussed between the leading economists worldwide. After the financial crises in the 1990ââ¬â¢s they suggested for developing countries to choose a corner solution and all intermediate exchange rate regimes were dismissed in order to be too risky. But in 2003, after the crisis of Argentina had reached its peak, the bi-polar view might be a good solution as well. The next section will be examine what Argentina did try to escape the crisis, after they had already implemented a currency board (fixed exchange rate), which eventually, with a lot of accompanying factors, evoked the crisis. They actually started floating their currency and implemented several other measures to save their economy. If this mixture of policies was successful will be analyzed in the following. 2. 1 Fixed exchange rate vs. floating exchange rate regimes For a better understanding what the next section is talking about, a brief introduction about the different exchange rate possibilities and their advantages and disadvantages will be implemented. A fixed exchange rate regime can be created in three different ways. The first two are either a Soft Peg or a Hard Peg of the currency. Hard Pegs are for example currency boards or currency Unions (Eurozone) and mean a complete fix to the currency of a foreign country (e. g. the currency board of Argentina pegged the Peso to the Dollar). Soft Pegs are the less strict version and link to other currencies is less direct. The third possibility is a fixed exchange rate peg to several countries. The main focus of this paper lies on the currency board as it was the case in Argentina. The main economic advantage of a hard peg (currency board) is, that it comes to a better trade between the countries that are part of the arrangement. Since the volatility of floating rates causes costs for exports and imports. It also encourages international capital flows which can profit the welfare of a country. Especially in case of developing countries these capital flows can be very large. One big Problem of the exchange rate regimes is the loss of monetary and fiscal possibilities to stabilize the economy as well as Limitation of the ability to pursue domestic goals. There is a slight difference between a hard peg and a fixed exchange rate, since the fix exchange rate can be with several countries whereas the hard peg only pegs it currency to one foreign country. They have more or less the same ad- and disadvantages, but with a fixed exchange rate, which is pegged to more than one country, the pursuit of domestic goals is easier, since the country does not depend on one foreign economy. One major weakness of the fixed exchange rate is, that when devaluation becomes necessary through fundamental changes in economy. Even the announcement of devaluation creates the danger of a crisis and eventually ends in a crisis, like the case of Argentina shows. It is also likely that a currency crisis after devaluation can end up in a banking crisis, since fixed exchange rates give incentives to take on debt. see below for further information) Floating exchange rates can be found for example in the arrangement of the U. S. with their major trading partners. It means that the value of the exchange rate will be freely determined in the market, depending on demand and supply. The main economic advantages of floating exchange rates are that they leave the monet ary and fiscal authorities free to pursue internal goals. They can concentrate to generate full employment, stable growth, and price stability. Exchange rate adjustment often works as an automatic stabilizer to promote those goals. One main disadvantage of floating exchange rates is, that the exchange rate volatility and uncertainty, concerning costs on trade and investments, may discourage international investment. If foreign investment is a main source, as it is the case for most developing countries, floating exchange rate may impose real costs, not only for the exporters but also for the whole society. Whether a country should choose a fixed or a floating exchange rate depends on the dependency of the country on their neighbors and therefore their sensibility to external shocks. If it is very dependent on their neighbors and especially their neighborsââ¬â¢ economy the country is better of with a fixed exchange rate. But if the country is economically independent, a floating exchange rate would be the better choice in order to favor macroeconomic stability. 2. 2 Two types of exchange rates and free floating currency As the era of the currency board of Argentina was described earlier, the following focuses on the measures taken after the default of Argentina. The government chose a mixture of the two strategies mentioned before. Duhalde implemented his measures in a ââ¬Å"schizophrenicâ⬠way. They started to devaluate the Peso from the originally 1 Peso to 1 Dollar rate to a 1. 4 pesos to 1 dollar rate (January 6 2002). On January 9th the government ââ¬Å"pesifiedâ⬠dollar assets and liabilities, by converting the dollar to pesos at a 1 to 1 rate. This led to a ââ¬Å"massive destruction of property rightsâ⬠and a lot of utilities and companies ended up in bankruptcy. On February 9th they floated the peso by using the asymmetric pesification. This meant that dollar deposits were converted to pesos at the rate of 1 to 1. and dollar loans converted to pesos one to one. This imposed a large loss on the banking system and favored debtors owing dollar debts. A wide range of dollar denominated debt would be converted into pesos at the old parity of one peso to one dollar. The holders of dollar deposits in the bank could convert those at a much more favorable exchange rate 1. 4 pesos to one dollar. It followed a great loss on the balance sheet of the Banks, who could only remain one peso for one dollar in debt owed by borrowers but owed 1. 4 peso for each dollar to the debtors. The asymmetric pesification amounted a total loss of $ 10- 15 Million Dollar compared to their equity of $ 17 million they had at the end of 2001. The government finally realized that it could not risk a total collapse of the banking system and offered to help the banks. They granted $ 9 million in the form of government bonds in order of compensation. This compensation covered most of the losses in nominal accounting but since the market value of the bonds was far below par not in real terms. 2. 2 Free floating currency http://www. nber. org/papers/w9808. pdf? new_window=1 in many emerging market economies, exports, imports, and nternational capital flows are a relatively large share of the economy, so large swings in the exchange rate can cause very substantial swings in the real economy. (p6) Under these circumstances, the monetary authority is likely to display ââ¬Å"fear of floatingâ⬠(Calvo and Reinhart, 2002), defined as a reluctance to allow totally free fluctuations in the nominal or real exchange rate, which Mussa (1986) showed are very closely linked. To ââ¬Å"pesofyâ⬠all savings and debts Currency apparently has destroyed more the trust into the financial sector than the hyperinflation in 1989 did, although it was created to generate more trust. Argentina suffered from diverse devaluations of other currencies and then they devaluated their own currencies. Which effects did that have on other economies and their own? This question will be answered in the following section. 3. Effects of Devaluation process on 3. 1 Trade Balance 3. 2 Productive capacity 3. 3 Salaries 3. 4 National Accounts 4. Conclusion 5.

Materials and Methods - Fly Experiment free essay sample
A heterozygous female will always display the dominant wild-type gene if present. The uncertainty of female genotype is cleared by the acquisition of an F0 stock which is homozygous dominant or recessive. Determining Sex Aside from determining eye colour, recognising the sex of D. melanogaster was paramount to this experiment. This can be accomplished by observation of the unconscious flies through the dissecting microscope. Males are distinguishable by the presence of heavy dark bristles surrounding the male genitalia, bristles not present on the females. Examination of the front legs provided another distinction, as males carry a sex comb which females do not. Size and shape cannot be used to determine sex as both vary depending on age. The abdomen of an older male will be darker than that of an older female; however abdominal colour also varies with age, making it an unreliable method of sexing. Life Cycle Observed throughout the experiment were four life stages of D. We will write a custom essay sample on Materials and Methods Fly Experiment or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page melanogaster. Eggs hatch a day after being laid by the female, and are in 1st instar larval form. Over the next 6 days, the larvae would molt to the 2nd and 3rd instar. The cuticle of the 3rd instar hardens into a pupa, and after 6 days in the puparium, metamorphosis is complete and the adult fly forces its way through the anterior end of the puparium. Older males would attempt to mate with very young females; therefore it was important to be vigilant in removing all adult flies prior to the emergence of the newest generation. This was done at one week intervals. The flies were raised in vials with a commercially available medium supplying all nutrients, with a new medium prepared for each new generation. Handling D. elanogaster First and foremost in the handling of Drosophila melanogaster was to ensure that the specimens were not exposed to condensation at any time, as this is fatal to the flies. Transportation, examination and counting were all accomplished with the flies unconscious, a reaction triggered by cold temperatures. Vials containing the specimens were put on ice for five minutes, and during examination under a microscope, the sorting pl ate was placed over a petri dish filled with ice. Once unconscious, flies were sucked into vials with an aspirator. Care was taken at all times to be gentle with the specimens, and a sable paintbrush was used to move the specimens around to avoid damage, however those that were damaged were discarded into a supplied oil jar (morgue). Experimental Procedure For the small population group, a population of four males and four females was established, two of each eye colour per sex. All eight flies were placed in the culture vial still unconscious after sexing (care must be taken to keep the vial on its side until all specimens are conscious, or the flies will become stuck to the medium), and the culture vials stored at room temperature for a week. For the large population group, an initial population of 40 was established. This population consisted of 20 males and 20 females, 10 of each eye colour per sex. The same procedure was followed as with the small population. After a one week period, the initial population was removed from the two vials, the eight parents from the small population and the 40 parents from the large population. One week after the removal of the parents, the first data was recorded. Eight flies (four male, four female) were randomly removed from the small population, and 40 flies (20 male, 20 female) were randomly removed from the large population.

Essay on Psychology and Children
Essay on Psychology and Children Essay on Psychology and Children CU1520.4-Understand how working practises can impact on the development of children and young people. 1. Explain how own working practise can affect children and young peopleââ¬â¢s development As a practitioner it is our duty to observe and maintain the right procedures to ensure that the children are offered an exciting environment which will allow the best possibilities for development. So it can be stated that how we set up our own working practices can affect children and young peopleââ¬â¢s development. As, role models we need to practice good behavior methods for example, saying 'Please' and 'Thankyou' to the manner of our voice as we use to speak to one another. Children are able to sense any kind of atmosphere even when adults are speaking between each other. It is important to encourage children to understand the importance of good physical and mental health through their diet, exercise and healthy lifestyle. If we do not promote and encourage a healthy and balanced lifestyle, it could result in the children having poorly developed immune system which in turn would cause them to be ill and have days off school which would affect their development. Promoting good hygiene is very important. In my nursery we encourage hygiene throughout the day. We do this by washing the tweeniesââ¬â¢ hands before meal times, we take them to the toilets to do this. As they have been doing this for a while they are used to the routine. They ask for the soap themselves and they know they have to dry their hands with the paper towels. Also when the children have eaten they wipe their hands and face with wet flannels, again as they are used to this idea most of the children ask themselves for the flannels when they have eaten. 2. Explain how institutions, agencies and services can affect children and young peoples development. Speech and language can help children overcome most of their problems. By helping children gain the ability to use language they can help children gain confidence and self-esteem I have seen this in my setting with children who have had communication and language needs. These children have gained confidence and their language is now at a level that they can interact with other children and not show frustration. This is because they can now express themselves. The Senco is in an educational setting that gives support to children and families with special need, this person is also responsible for identification of special needs. Other learning support staff work within and outside schools providing a range of services to help children who have certain specific educational needs. This might include people like teaching assistants or advisors to provide support and train staff. Also Youth justice are based on children with behavioural problems these people will work with them and social workers to help them. Social workers help vulnerable children and young people and their families this might include children on the child protection register or disabled children. A Psychologist is a professional who helps support children

In this article, well look at some real functional Sinatra code, touching on a few Sinatra features, all of which will be explored in depth in upcoming articles in this series. Before you get started, youll have to go ahead and install Sinatra. Installing Sinatra is as easy as any other gem. Sinatra does have a few dependencies, but nothing major and you shouldnt have any problems installing it on any platform. $ gem install sinatra Hello, World! The Sinatra Hello world application is shockingly simple. Not including the require lines, shebang and whitespace, its just three lines. This is not just some small part of your application, like a controller in a Rails application, this is the entire thing. Another thing you may notice is that you didnt need to run anything like the Rails generator to generate an application. Just paste the following code into a new Ruby file and youre done. #!/usr/bin/env rubyrequire rubygemsrequire sinatraget / doHello, world!end Of course this isnt a very useful program, its just Hello world, but even more useful applications in Sinatra arent much larger. So, how do you run this tiny Web application? Some kind of complex script/server command? Nope, just run the file. Its just a Ruby program, run it! inatra$ ./hello.rb Sinatra/0.9.4 has taken the stage on 4567 for development with backup from Mongrel Not very exciting yet. Its started the server and bound to port 4567, so go ahead and point your Web browser to http://localhost:4567/. Theres your Hello world message. Web applications have never been so easy in Ruby before. Using Parameters So lets look at something a little more interesting. Lets make an application that greets you by name. To do this, well need to use a parameter. Parameters in Sinatra are like everything elsesimple and straightforward. #!/usr/bin/env rubyrequire rubygemsrequire sinatraget /hello/:name doHello #{params[:name]}!end Once youve made this change, youll need to restart the Sinatra application. Kill it with Ctrl-C and run it again. (Theres a way around this, but well look at that in a future article.) Now, the parameters are straightforward. Weve made an action called /hello/:name. This syntax is imitating what the URLs will look like, so go to http://localhost:4567/hello/Your Name to see it in action. The /hello portion matches that portion of the URL from the reqest you made, and :name will absorb any other text you give it and put it in the params hash under the key :name. Parameters are just that easy. There is of course much more you can do with these, including regexp-based parameters, but this is all youll need in almost every case. Adding HTML Finally, lets spiff this application up with a little bit of HTML. Sinatra will return whatever it gets from your URL handler to the web browser. So far, weve just been returning a string of text, but we can add some HTML in there with no problem. Well use ERB here, just like is used in Rails. There are other (arguably better) options, but this is perhaps the most familiar, as it comes with Ruby, and will do fine here. First, Sinatra will render a view called layout if one exists. This layout view should have a yield statement. This yield statement will capture the output of the specific view being rendered. This allows you to create layouts very simply. Finally, we have a hello view, which generates the actual hello message. This is the view that was rendered using the erb :hello method call. Youll notice that there are no seperate view files. There can be, but for such a small application, its best to keep all the code in a single file. Though the views are sepeated at the end of the file. #!/usr/bin/env rubyrequire rubygemsrequire sinatraget /hello/:name doname params[:name]erb :helloend__END__ layouthtmlbody% yield %/body/html helloh3Hello % name %!/h3 And there you have it. We have a complete, functional hello world application in about 15 lines of code including the views. The following articles, well take a closer look at the routes, how you can store and retrieve data, and how to do better views with HAML.

As the societies are becoming litigious, it is important to integrate the aspect of ethics into the volunteer programs. The case will help to bolster an understanding toward the expectations of the communities. Besides, the level of ethics incorporated into the volunteer activities will accentuate the levels of open-mindedness, realism, and the extent of being informed. Further, the situation will guide professional development due interactions with many people from diverse settings (Samuel, Wolf & Schilling, 2013). In the contemporary arena, many people aspire to give back to their communities. Volunteering in a myriad of activities helps in the realization of this situation. The volunteer activities bring moments of happiness into the other peopleââ¬â¢s lives through helping them achieve what they desire (Angood, 2015). Similarly, long-term volunteer activities have lots of rewards to the doer as they satisfy their emotional and spiritual conceptions (Dekker, 2003). Moreover, the beneficiaries will have their social lives enhanced and a there will be a smile left after termination of the volunteer activities. The volunteers will have better social and relational skills, gain experience, build confidence, and retain their physical health (Jenkinson, 2013). Compounded in leadership, volunteerism should build on the principles such as; having a realization that missions motivate while maintenance does not. In this context, the organizations such as the ODNRA need to develop strong missions and mission statements that help and guide the volunteers in the execution of their duties and responsibilities (Volunteer Government, 2015). Also, as a leader, one should avoid falling prey to the trap of a generalist or a specialist. Contextually, the leader must have it in mind that the sole duty is to influence and not to
