Insect Behavior, Communication and Learning

Insect Behavior, Communication and Learning Most insect behavior is genetically programmed, or innate. A caterpillar with no prior experience or instruction can still spin a silken cocoon. But can an insect change its behavior as a result of its experiences? In other words, can insects learn? Insects Use Memories to Change Their Behavior You wont see one graduating from Harvard anytime soon, but indeed, most insects can learn. Smart insects will change their behaviors to reflect their associations with and memories of environmental stimuli. For the simple insect nervous system, learning to ignore repetitive and meaningless stimuli is a fairly easy task. Blow air on a cockroachs rear end, and it will flee. If you continue to blow air on the cockroach over and over, it will eventually conclude that the sudden breeze is no cause for concern, and stay put. This learning, called habituation, helps insects save energy by training them to ignore what is harmless. Otherwise, the poor cockroach would spend all its time running away from the wind. Insects Learn From Their Earliest Experiences Imprinting occurs during a brief period of sensitivity to certain stimuli. Youve probably heard stories of baby ducks falling in line behind a human caretaker, or of nesting sea turtles that return to the beach where they hatched years earlier. Some insects also learn this way. Upon emerging from their pupal cases, ants notice and retain the scent of their colony. Other insects imprint on their first food plant, showing a clear preference for that plant for the remainder of their lives. Insects Can Be Trained   Like Pavlovs dogs, insects can also learn through classical conditioning. An insect exposed repeatedly to two unrelated stimuli will soon associate one with the other. Wasps can be given food rewards each time they detect a certain scent. Once a wasp associates food with the smell, it will continue to go to that scent. Some scientists believe trained wasps may replace bomb and drug sniffing dogs in the near future. Honeybees Memorize Flight Routes and Communicate with Dance Routines A honeybee demonstrates its ability to learn each time it leaves its colony to forage. The bee must memorize patterns of landmarks within its environment to guide it back to the colony. Often, she is following the instructions of a fellow worker, as taught to her through the waggle dance. This memorization of details and events is a form of latent learning.

American History Questions - Essay Example He explains that the wealthy have failed to employ the poor immigrants living in the slums a feature that enhances the problems the slum dwellers face. In Aftershocks on the other hand, Reich argues that the large inequality gap between the wealthy and the middle class stoked the credit bubble thus leading to the crisis. Reich begins his book by countering the arguments by Timothy F. Geithner, the Treasury secretary at the time that the middle class was buying too much while saving too little. Reich believes that the middle class did not make adequate amounts of money and was instead employing a number of survival techniques none of which could sustain the economic growth. The difference in the book lies in their structures with Aftershocks is a book while Riis’ is a publication of photojournalism. I disagree with Mrs. Rodgers assessment that the era of the FDR a welfare state that continues to plague the country. I believe that President Franklin D. Roosevelt employed every feature including the welfare programs to help the economy and in deed, he did. He for example authorized the utilization of about $5 million in relief programs that sought to create employment for the public. The president understood the importance of employment in enhancing the economic growth. The public assistance relief program helped cushion the public from the adverse effects of the great depression. The Works progress Administration did not only see the development of mega infrastructure at a time the country was facing the worst economic crisis but also provided the citizenry with adequate income capable of sustaining their lives thus overcome the crisis. The country has consistently employed similar strategies including the systematic bailouts in 2007 and 2008 financial crisis that helped keep th e largest corporations operational. Inequality for all has been a factual indictment for the economic condition in the United

Feasability Study Report - Assignment Example Growing Business and Entrepreneurs (2008) suggests that India along with five countries account for nearly half the GDP of total world as measured in PPP. More than half of the world’s total population lives in just two countries of the world –India and China. Moreover these are the developing countries of the world which offer higher growth rate as compared to the already developed markets; and the economically developed countries like US and Germany are facing greater heat of recession with surging economic crises. Therefore the investment can be in either of India and China finally. There are a few points, however, that work in favor of India as compared to China which are as follows:- 1. Most of the people in India are well versed with English. So there will be no communication gap while working with the people of India which may not be the case in China. 2. Indian economy is more or less insulated with the global economy so the repercussions of the global meltdown will be minimized. 3. Chinese population has a higher ratio of old people whereas Singhal (2006) suggests that in India more than half of total population is below 25 years of age. Target consumer for the restaurants generally being young and dynamic, India offers better market penetration. 4. China has a poor record on human rights. 5. India has a closer association with the British culture than China.... Globalization has entered India in the year 1992. With the emergence of globalization, the GDP of the country has grown many folds in just a few years. Most of the major brands started outsourcing their work to India owning to the younger population of the country and the difference in the cost. With number of companies operating from India, the spending capacity of the youth has increased many folds. There is a close association of the country with British culture as the English have ruled the country as recently as 1947 A.D. which will definitely be suited to an Englishman. Moreover India generally offering outsourcing to western nations has westernized a lot in the last five years and most of the youth have started preferring Western meals to the traditional Indian spicy food. Owing to the sudden surge in the spending capacity and the latest trends of westernization offer a huge potential of growth to any authentic British restaurant. 'The Diner's Park', an authentic British restaurant, can therefore be finalized to start in Pune, the city having highest number of youths in the country. Moreover, the city has largest number of IT companies, 212 registered IT companies in 2007 as per the data reported by India Design Festivals (2009), in India. Come to the Diners Park and Feel the difference!! British Dining at its Best... The current supply side:- Most of the Indians quite like the Western culture as represented in the modern day trends in India. Currently there is a dearth of an authentic British restaurant in the city and the young crowd of India is food savvy. This is quite apparent from their behavior where they are

In theory, Parliament is sovereign in New Zealand. In practice, it is Essay

In theory, Parliament is sovereign in New Zealand. In practice, it is not - Essay Example Sovereignty and Function of New Zealand Parliament The New Zealand Legislature is Sovereign. The arm of government can call parliamentarians to meet. Secondly, it can dissolve parliament and assent to bills passed in the house before they become laws. The major function of the parliament is to make laws. The parliament also provides the government with members to be appointed in various ministerial positions. This enables the government to maintain majority and confidence among parliamentarians. The parliament also serves as a watchdog for the people by controlling and scrutinizing the government. The ministers are answerable to the parliament and are often asked questions in parliament regarding their ministries. The final function of the parliament is to represent the people in parliament. It fulfils this function by airing views and wishes of the electorate in parliament (NZCU South, 2013).   The three Arms of the Government The first arm of the government is the Executive. It i s made up of the crown that is represented by Governor-General, the cabinet ministers and the civil servants. The executive is concerned with initiating, developing and implementing government policy. It also publishes and administers legislations (Salter, 2013). The legislature has a single chamber called the House of Representatives. Its main duty is to make laws by drafting, evaluating and debating bills before they become laws. The people elect the MPs after every three years (Salter, 2013). The last arm of the government is the judiciary. It is made up of the judges and courts. Its main duty is to interpret and apply law as per the constitution. Apart from this, the judiciary punishes offenders and arbitrates any conflict between the legislature and executive (Salter, 2013). Powers of Parliament Various ways can be used to increase the powers of parliament. One of them is giving parliamentarians immunity when debating. According to this provision, parliamentarians will be free to express their views without fear of imprisonment. This would enable them to check the government without fear. The parliament should also be allowed to discuss any matter before the courts or the executive. The court and executive proceedings should not hinder parliamentary proceedings. This would enable the parliament to oversee implementation of government policies that are beneficial to the public. In addition to this, parliament should have the powers to summon any one including the members of the judiciary and the executive to question them on various matters of the state. Lastly, the parliament should be allowed to scrutinize and assent to all executive appointees in order to ensure they serve the public and not the executive (New Zealand Parliament, 2013). The role of Executives The executive is made up of the Prime Minister, Governor General, cabinet ministers, civil servants and government departments. The executive draft government bills and present them in parliament f or debating. It is also charged with developing and implementing various policies that would improve the welfare of the citizens. However, the sole function of the executive is to advise the Governor-General on his duties such as appointment of ministers. The ministers head various ministries such as finance and judiciary. Civil servants are charged with implementation of the

Effect of Carbon Atoms Number in Alcohol on Combustion

Effect of Carbon Atoms Number in Alcohol on Combustion Research Question How does the number of carbon atoms in the hydrocarbon chain of primary alcohol affect its enthalpy change of combustion? Independent Variable The independent variable in this investigation is the number of carbon atoms in the hydrocarbon chain of primary alcohol. Five different primary alcohol will be used, namely, methanol, ethanol, propan-1-ol, butan-1-ol and pentan-1-ol. Dependent Variable: The dependent variable in this investigation is the enthalpy change of combustion of primary alcohol. Enthalpy change of combustion is the energy released when one mole of fuel is completely burnt in oxygen to form carbon dioxide and water. To measure the enthalpy change of combustion, the heat given out during combustion is first absorbed by water which is calculated by q = mc à ¯Ã‚ Ã¢â‚¬Å¾T where m is the mass of water, c is the specific heat capacity of water and à ¯Ã‚ Ã¢â‚¬Å¾T is the temperature change of water. The heat given out is then divided by the number of moles of alcohol used during the investigation. As combustion is an exothermic reaction, a negative sign is added to give the final enthalpy change of combustion. Control Variables: The table below shows the variables that have to be controlled: Hypothesis: The higher the number of carbon is in the hydrocarbon chain, the greater the enthalpy change of combustion of the primary alcohol. One of the evidence for this hypothesis comes from the IB Chemistry data booklet. The standard enthalpy change of combustion for methanol, ethanol, propan-1-ol and butan-1-ol are –726 kJmol-1, –1367 kJmol-1, –2021 kJmol-1 and –2676 kJmol-1 [1]respectively. Another way to get this trend is to use the average bond enthalpy to estimate the enthalpy change of combustion. Though average bond enthalpies are just average values only, they do give an insight on the trend of the enthalpy change of combustion of different alcohol. The general formula for alcohol is CnH2n+2O. The general equation for combustion of alcohol is CnH2n+2O (l) + 1.5nO2 (g) à ¯Ã†â€™Ã‚   nCO2(g) + (n+1)H2O(l) When the number of carbon increases by one, the following table shows the extra bonds to be broken and extra bonds formed: The average bond enthalpies for the above bonds are shown in the table below: [2] The net change in enthalpy change when one more carbon is added = + 2 Ãâ€" 413 + 347 – 2 Ãâ€" 746 – 2 Ãâ€" 464 = – 1247 kJmol-1 Thus, the enthalpy change of combustion of primary alcohol will decrease by 1247 kJmol-1 (more negative) when one more carbon is added to the hydrocarbon chain. Apparatus: 100 cm3 measuring cylinder ( ±1 cm3) Ãâ€" 6 (one for each alcohol and the other for water) (2 d.p. ) Electronic balance ( ±0.01 g) Ãâ€" 1 Tripod Ãâ€" 1 Copper container with lid Ãâ€" 15 (one for each trial) Stand and clamp Ãâ€" 1 (use to hold the thermometer in position) Mercury in glass thermometer ( ±0.1à ¯Ã¢â‚¬Å¡Ã‚ °C) Ãâ€" 2 (one is used to measure temperature of water and the other used for monitoring the temperature of surrounding) Stirrer Ãâ€" 1 Aluminium heat shield Ãâ€" 4 (to reduce heat loss) Spirit burner with wick Ãâ€" 15 (one for each trial) Lid Ãâ€" 1 (for extinguishing the flame) Stopwatch ( ±0.01 s) Ãâ€" 1 Ruler ( ±0.1 cm) to measure the length of wire and the position of the thermometer Scissor Ãâ€" 1 (used to cut the wick) Chemicals 750 cm3 of distilled water (50 cm3 for each trial) 100 g of each of the following primary alcohol at a concentration of 90%. Methanol, ethanol, propan-1-ol, butan-1-ol and pentan-1-ol Procedures Prepare a spirit burner. Cut the length of its wick to approximately 3.0 cm (the portion outside the burner) with a pair of scissors and a ruler. Measure 50 cm3 of methanol with a 100 cm3 measuring cylinder and pour it in a spirit burner. Weight the spirit burner with an electronic balance. Record the mass of the spirit burner in the table below. Measure 50 cm3 of distilled water with another 100 cm3 measuring cylinder and pour it in a copper container. Place the copper container on a tripod and cover it with a lid. Use stand and clamp to hold a thermometer in the beaker of water. Use a ruler to make sure that the bottom of the thermometer is 1.0 cm from the bottom of the beaker and make sure the thermometer is approximately located at the centre of the beaker. Record the initial temperature of the water and put it in the table below. Place a stirrer in the water. Stir the water throughout the process of heating. Surround the whole setup with heat shield made of aluminium to reduce heat loss. Ignite the wick of the spirit burner with a lighter. Place the spirit burner under the beaker. Immediately start the stopwatch and wait for two minutes. Stop the stopwatch after two minutes. Use a lid to extinguish the flame. Record the highest temperature reached by the thermometer and put it in the table below. Allow the spirit burner to cool. Weigh the final mass of the spirit burner with an electronic balance. Put the mass in the table shown below. Repeat the experiment (Step 1 to 16) two more times. Repeat the same experiment (Step 1 to 17) for other primary alcohols (i.e. ethanol, propan-1-ol, butan-1-ol and pentan-1-ol). Table for recording raw data and some processed data: Data Processing The mass of fuel used (m) is calculated by subtracting the final mass of spirit burner from the initial mass of spirit burner. The temperature change (à ¯Ã‚ Ã¢â‚¬Å¾T) is calculated by subtracting the final temperature by the initial temperature. The heat (q) absorbed by water can be calculated by the formula q = mc à ¯Ã‚ Ã¢â‚¬Å¾T where m is the mass of water used: 50 g (as the density of water is 1 g cm-3) c is specific heat capacity of water: 4.18 Jg-1K-1 Number of moles of fuel used can be calculated by dividing the mass of fuel used (m) by the molar mass of the fuel. The molar mass is found by adding up the relative atomic mass of the element involved. For example, the molar mass of methanol (CH3OH) is 12.01 + 4 Ãâ€" 1.01 + 16.00 = 32.05 gmol-1. The enthalpy change of combustion of alcohol is found by dividing the heat by the number of moles of fuel with a negative sign added to show that it is exothermic. A graph is plotted with enthalpy change of combustion (y-axis) against the number of carbon atom is the hydrocarbon chain of the primary alcohol (x-axis). Compare this graph with the graph in the hypothesis. Safety Alcohols are flammable. Avoid naked flame near alcohol. [1] Chemistry data booklet (First examinations 2009).

The Limits of Software Liability Essay -- Legal Business Technology

"Faulty software can cost lives, cause injury, or economic damage. Write an essay to investigate the question, under which circumstances a software company should be liable for the damage caused. Use an example where software failures are potentially dangerous, such as that of the Prius's brake software. Discuss the difference between strict and negligent liability and comment on the social and economic impact stricter liability practices for software could have." It is remarkable, that nowadays, we have complex software systems everywhere. We have them in our dishwashers, and in our wristwatches, though they are not quite so mission-critical. But sometimes, the human factor can be devastating, because of the negligence or the strict liability who dominates, and often devastating implications not only for the man himself, but can affect the whole economy of a country, succeeding or at least trying to succeed, ignoring the institutions, rules and contract. A highly representative example of the failure of human factors in an attempt to â€Å"progress† with the help of a software, is Ariane 5 explosion, that was the cause of a huge economic gap. It took the European Space Agency 10 years and $7 billion to produce Ariane 5, a giant rocket capable of hurling a pair of three-ton satellites into orbit with each launch. It intended to give Europe overwhelming supremacy in the commercial space business. There was no risk of lightning since the strength of the electric field in the spray was negligible. Perhaps, one problem, leading the explosion, was the visibility. The countdown, which also comprises the filling of the core stage, went smoothly until the first seven minutes when the launch was put on hold since the visibility criteria ... ... at what determines the law and contracts, addressing scientists. Lastly, let us continue our efforts to improve our world, even with technological wonders. Works Cited ARIANE 5 / Flight 501 Failure / Prof. J. L.
