Problems in Gov essays

Problems in Gov essays Major issues state governments confront in the U.S. are basic issues that people have a lot to say about. These issues are interest group pressure, waste management, gambling, abortion, gun control, capital punishment, and emergency services. But first lets look at why people vote or do not vote. Why vote is a question that people try and figure out but just can not see reasons why they should take the time to make there way out on an election day and cast there vote. Local and state elections get about 30% of the people in there county, city, or state to come out and vote. Presidential elections always get larger amounts of people to come out and vote. Why do people stay home on Election Day? In class we rationally theorized to try and understand the nonvoting in the states. We came up with a few reasons, they are as follows: Registration requirements that are restrictive, there must be a good competition between the candidates, and peoples civic attachments and education. Hate, l ie, and vote this is the way a rational voter thinks. Rational voters are ones who seek to maximize personal benefits and minimize costs. Then you have your loyal voter. A loyal voter is someone who votes every time and is there for every election, no matter what its for. People who are loyal voters are usually old, wealthy, educated, and/or white. It takes a certain type of person to run for office or participate in the election campaign in someway. The following percentages are of the people who participate in politics: How do you get people to vote/register to vote? You could go door to door to peoples houses, usually job of a councilman. When someone applies for a license they have an opportunity to register. This is the Voter/Motor Law. When a person applies for welfare they have the opportunity to apply to vote also. This is part of the welfare reform. People will go to the polls when they feel that the election is close because t...

French Verbs of Perception Follow Their Own Drum Beat

French Verbs of Perception Follow Their Own Drum Beat French verbs of perception are verbs that, logically enough, indicate a perception or sensation. There are six common French verbs of perception:   Ã‚  Ã‚  apercevoir   to catch a glimpse of  Ã‚  Ã‚  Ãƒ ©couter  Ã‚  to listen to  Ã‚  Ã‚  entendre  Ã‚  to hear  Ã‚  Ã‚  regarder  Ã‚  to watch  Ã‚  Ã‚  sentir  Ã‚  to feel  Ã‚  Ã‚  voir  Ã‚  to see Verbs of perception and sensation may be followed by a noun or an infinitive. Note that in this construction, the French infinitive following the verb of perception is often translated into English as a present participle.For example:   Ã‚  Japerà §ois un arbre.I see (a glimpse of) a tree.   Ã‚  Ã‚  Japerà §ois tomber un arbre.I see (a glimpse of) a tree falling.   Ã‚  Jà ©coute les enfants.Im listening to the children.   Ã‚  Ã‚  Jà ©coute parler les enfants.Im listening to the children talking.   Ã‚  Ã‚  Jentends les à ©tudiants.I hear the students.Jentends arriver les à ©tudiants.I hear the students arriving.   Ã‚  Ã‚  Je regarde là ©quipe.Im watching the team.   Ã‚  Ã‚  Je regarde jouer là ©quipe.Im watching the team play.   Ã‚  Ã‚  Je sens le vent.I feel the wind.Je sens souffler le vent.I feel the wind blowing.   Ã‚  Ã‚  Je vois le chien.I see the dog.Je vois courir le chien.I see the dog running.   Word Order With Verbs of Perception Word order with French verbs of perception depends on whether the infinitive has a subject and/or object and whether these are nouns or pronouns.  How do you know whether the noun or pronoun that precedes the verb is the subject or the direct object? If the noun or pronoun is the person or thing performing the action of the infinitive, it  is the subject of the infinitive. If the person or pronoun is not performing the action but rather is being performed by the infinitive, it is the direct object. When the infinitive has either a subject pronoun or object pronoun, it must be placed in front of the main verb. Subject   Ã‚  Ã‚  Jentends les enfants arriver.(I hear the children arriving.)Je les entends arriver.Je regarde la fille à ©crire.(I see the girl writing.)Je la regarde à ©crire. Object   Ã‚  Ã‚  Jentends lire  lhistoire.(I hear the story being read.)Je lentends lire.   Ã‚  Ã‚  Je  vois  coudre  une robe.(I see the dress being sewn.)Je la vois coudre. If the infinitive has a non-pronoun direct object and no subject, it must be placed after the infinitive.   Ã‚  Ã‚  Jentends lire lhistoire.(I hear the story being read.)   Ã‚  Ã‚  Je vois coudre une robe.(I see the dress being sewn.)   Ã‚  Ã‚  Je regarde nettoyer la chambre.(Im watching the room being cleaned.) If the infinitive has a non-pronoun subject and no object, the subject can be placed either before or after the infinitive.   Ã‚  Ã‚  Jentends les enfants arriver.Jentends arriver les enfants.(I hear the children arriving.)   Ã‚  Ã‚  Je regarde la fille à ©crire.Je  regarde  Ãƒ ©crire la fille.(Im watching the girl write.)   Ã‚  Ã‚  Je sens le vent souffler.Je sens  souffler  le vent.(I feel the wind blowing.) If the infinitive has a non-pronoun subject as well as an object, you must place the subject in front of the infinitive and the object after it.   Ã‚  Ã‚  Jentends les enfants casser le jouet.(I hear the children breaking the toy.)   Ã‚  Ã‚  Je regarde le monsieur à ©crire une lettre.(Im watching the man write a letter.)   Ã‚  Ã‚  Je sens le vent caresser ma peau.(I feel the wind caressing my skin.) If the  subject  is a pronoun  (a.), it precedes the conjugated verb. If the  object  is a pronoun  (b.), it precedes the infinitive.   Ã‚  Ã‚  a.  Je les entends casser le jouet.(I hear them breaking the toy.)b.  Jentends les enfants le casser.(I hear the children breaking it.)   Ã‚  Ã‚  a.  Je le regarde à ©crire une lettre.(Im watching him write a letter.)b.  Je regarde un monsieur là ©crire.(Im watching a man write it.)   Ã‚  Ã‚  a.  Je le sens caresser ma peau.(I feel it caressing my skin.)  b.  Je sens le vent la caresser.(I feel the wind caressing it.) If both the subject and object are pronouns, you must place the subject in front of the main verb and the object after it.   Ã‚  Ã‚  Je les entends le casser.(I hear them breaking it.)   Ã‚  Ã‚  Je le regarde là ©crire.(Im watching him write it.)   Ã‚  Ã‚  Je le sens la caresser(I feel it caressing it.) Agreement With Verbs of Perception The rules of agreement for verbs of perception in the compound tenses are a bit different than for other verbs. Rather than agreeing with the direct object, as for most verbs conjugated with avoir in the compound tenses, verbs of perception only require agreement when the subject precedes the verb.  How do you know whether the noun or pronoun that precedes the verb is the subject or the direct object? If it is the person or thing performing the action of the infinitive, it is the subject of the infinitive and follows agreement  rule 1  below. If it is not performing the action but rather is being performed on by the infinitive, it is the direct object and follows  rule 2  below. 1.  If the  subject  of the infinitive precedes the verb of perception, there is agreement:   Ã‚  Ã‚  Jai vu  tomber  la fille.I saw the girl fall.La fille que jai  vue  tomber.Je  lai  vue  tomber.   Ã‚  Ã‚  Jai regardà ©Ã‚  les  enfants  Ãƒ ©crire.I watched the children write.Les  enfants  que jai regardà ©s à ©crire.Je  les  ai regardà ©s à ©crire.   Ã‚  Ã‚  Jai  entendu  arriver  les  Ãƒ ©tudiants.I watched the students arrive.Les à ©tudiants que jai entendus arriver.Je  les  ai  entendus  arriver. 2.  There is no agreement with the  direct object  of the infinitive.   Ã‚  Ã‚  Jai vu  les  enfants  Ãƒ ©crire  les  lettres.(Enfants  is the subject;  lettres  is the direct object. Even if we leave out  enfants,  lettres  is still the direct object, so there is no agreement.)Jai vu à ©crire  les  lettres.I saw the letters get writtenLes lettres que jai vu à ©crire.Je  les  ai vu à ©crire.   Ã‚  Ã‚  Jai entendu le monsieur lire une histoire.(Monsieur  is the subject;  histoire  is the direct object.)Jai entendu lire une histoireI heard a story get read.Lhistoire que jai entendu lire.Je lai entendu lire.   Ã‚  Ã‚  Jai à ©coutà © une fille chanter les cantiques.(Fille  is the subject;  cantiques  is the direct object.)Jai à ©coutà © chanter les cantiques.I listened to the hymns (get) sung.Les cantiques que jai à ©coutà © chanter.Je les ai à ©coutà © chanter.

Death penalty Term Paper Example | Topics and Well Written Essays - 1000 words - 2

Death penalty - Term Paper Example g at sea and crucifixion (Melusky & Pesto 8).Unlike in the present where many people do not witness such punishments, in the past death penalties were done in public. Apart from explaining on various forms of death penalties, the essay will also relay more information on its effects to the society. In the US, before the rise of legal institutions, cases of death penalties were quite rampant in all states. Since there were no modern legal institutions, many crimes ranked as capital whose punishment was death. For instance, in the US, crimes such as rape, kidnapping, arson and forgery were punishable by death (Walker 19). Most of these crimes were punishable by hanging and the process normally took place in public places where everybody would see. In the past, such events were quite common and usually attracted a large number of spectators some of whom came to do business during the occasion (Melusky & Pesto 2). Tens of thousands normally showed up in such events with the intension of viewing the hanging. This changed as from the 1960s when a modern legal institution was set up. To date, there have been numerous debates on the whether sentencing a person to death is justice as claimed. Most legal firms claim that a death penalty is justice only if one has committed a capital crime such as killing another person. Legal officers claim that one ought to receive punishment that is equal to the crime he or she has committed. According to Guernsey (9), even Biblically, an offender was to receive an eye for an eye; this implied that punishment was to fit the crime committed. Studies show that death penalties began in the US around the 1600 when the first English colonialists landed in the US (Guernsey 10). Captain George Kendall went down on record as the first person to die because of a death sentence. According to Melusky and Pesto (7), Captain Kendall was sentenced to death by the firing squad method. This was after an accusation of spying for the Spanish nation

HRM 'Managing Human Resources' Assignment Example | Topics and Well Written Essays - 1750 words

HRM 'Managing Human Resources' - Assignment Example The HRM function is of particular importance in the post-industrial economy (Harris, 2003) In this emerging system, the critical factor in production has shifted from machines and equipment to the "knowledge" worker (Marchington, 2002). That is, service has replaced production as the driving force in the economy, and the prominent way value is added is through the expertise of knowledge workers and the ministrations of service providers. In systems like this, it becomes even more important to obtain and use the full talents of all employees in the organization. Thus, the skilful adoption and use of HRM policies becomes a significant lever through which to move and direct the performance of the organization. As Gibb (2000) noted, HRM is really a series of policy choices about how employees are to be treated, paid, and worked. These policies will in turn impact and condition the nature of the employment relationship. Different policies lead to different outcomes in employee commitment, competence, and congruence with organizational goals. Likewise, each policy choice presents the decision maker with a distinctive cost and benefit alternative. For example, compensation policy choices to pay either at the low, average, or high end of the labour market have rather dramatic implications for employee commitment to the organization and for costs to the employer. The fundamental rationale for effective management of human resources should be to identify and implement those policies, programs, and procedures that will yield the desired levels of loyalty, skill, and direction in the most cost-effective manner possible. In this sense, HRM offers to organizational decision makers a set of people in vestment opportunities. Managing human resources effectively has never been as important as it is today and will be tomorrow. In today's service economy of knowledge-based, high-discretion jobs, the commitment and competence of employees can spell the difference between those organizations that win and those that are merely in the race. Establishing policies, programs, and practices that produce these results on a cost-effective basis and comply with laws and regulations is a complex undertaking. HRM can and should play a strategic role in the management of the organization. According to Chandy (2001), a large number of organizations have encountered severe difficulties finding personnel in recent years. We have little knowledge about how organizations are coping with these difficulties and are going about hiring staff. Considering the supply/demand trends of the last few decades - when the labour market used to be a buyers' market and a considerable pool of unemployed formed a buffer that could absorb cyclic fluctuations in labour demand - it is almost not astounding that most studies focused on employees' job seeking activities. (Chandy, 2001, pp 403-405) Research on the theoretical and empirical facet of organizations' behaviour to find appropriate staff, has studied first and foremost the selection behaviour: how to select personnel from a group of applicants. Nearly all vacancies are filled from a group of applicants that is created soon after posting the vacancy. On account of the economic expansion of the first

Reducing your carbon footprint Research Paper Example | Topics and Well Written Essays - 750 words

Reducing your carbon footprint - Research Paper Example The term itself, Carbon Footprint, has very little to do with drawings or the footsteps we make in the sand. In this case, the term is a metaphor for the way that our activities impact the resources of the planet. Carbon Footprints relate to the way we use the natural resources of the planet and how fast we use it. Therefore, a Carbon Footprint: â€Å"... is a shorthand to describe the best estimate that we can get of the full climate change impact of something. That something could be anything – an activity, an item, a lifestyle, a company, a country or even the whole world.† (Berners - Lee, Mike â€Å"What is a Carbon Footprint?†). Using this definition, it is easy to understand that we all participate in releasing carbon emissions and leaving our carbon footprints on the planet. Everything we do, from breathing to throwing away a piece of chewed up gum, has a direct effect on the health of the planet and our environment overall. That is why it is of the utmost importance that we learn to reduce our carbon footprints as we live our lifetime. Global warming is the method by which our planet is letting us know that it is ill. Since the signs of illness exist, it is up to us to cure it of the illness. Unlike human beings who can go to doctors for medication, our planet works differently. We are all its doctor. Our actions can either cure the illnes of make everything worse. According to Hayley Morris, founder and director of Impact Sustainability: Effective carbon management strategies along with corporate social responsibility provide us, as individuals and as businesses, with the foundation to ease that pressure and reduce the size of our carbon footprint that is stamping down on the tail of our beloved environment. Until recently as a society we have been coasting along the same old road, consuming every part of the environment we can possibly get our hands on without any regard for or awareness of the damage we may be doing to it (Morris , Hayley â€Å"reducing Carbon Footprint Benefits You and the Environment†). In other words, we are the cause of what is ailing the planet. By actively pursuing activities that increase carbon emissions into the air and decrease the planet's ability to reproduce our needed natural supplies such as food and chemicals for exygen creation, we are stifling the planet's ability to grow and nurture our existence on it. Climate change is a serious problem that is directly affected by the carbon footprint emissions that we make. In order to slow down or cure the problem, we must strive towards reducing these carbon footprint emissions as best as we can. For starters, we can do simple things such as unplugging appliances when not in use, using public transport or biking once or twice a week to reduce carbon monoxide in the air, buying energy efficient appliances, and properly insulating our homes for the cold months. By implementing these changes, we will find that reducing our carbon footprints also has positive outcomes for us as individuals. For example, opting to walk or take a bike ride rather than taking the car of public transport during short trips will increase our physical activity. This will lead to â€Å"reduced obesity and heart disease among the population while also providing our environment with reduced global CO2 emissions, small particle pollution, noise, and injuries. Another health related benefit of reduced carbon footprints is that by making better dietary choices, such as

Dopamine Neuron Characteristics

Dopamine Neuron Characteristics Said Mohammed Al Hakmani The question of this assignment Discuss the characteristics of a dopamine neuron and how does this relate to what has been achieved in the culture dish. Introduction In our body a lot of organs that make our function of movement and control. Parkinson’s disease affect our move. It happen when there is a problem of the certain of nervous cells in the brain. The nerve cells make an important chemical is named dopamine. The dopamine sends signals to the part of the brain that controls movement. Also, the dopamine lets the move of our muscle smoothly. The Parkinson’s disease breakdown the nerve cells that make the dopamine. When the person do not have enough dopamine the problem of move can start and the person cannot control the way where to move. (1) Figure 1 shows the nerve cells in the brain (1) The Parkinson’s disease is progressive, which means it gets worse over time. But this happen slowly many years. Until now no one know what acutely makes the nerve cells breakdown. However, scientists are doing a lot of research to know the reason of the cells breakdown. Some study say Parkinson disease is gene abnormal in some people but so far there is enough proof to show that its always inherited.(1)Braak’s hypothesis proposes that the Parkinson’s disease begins in the digestive tract and in the brain’s centre of smell. The theory is supported by the fact that symptoms associated with digestion and smell happen very early on the disease. Professor Jia- Yi Lis research team has now been able to tack this process further, from the gut to the brain in rat models. The experiment shows how the toxic protein alpha-synculein is transfer from one cell to another before reaching the brain’s movement centre, giving increase to the characteristic of movemen t in the Parkinson’s disease. He prove that disease process actually can travel from the peripheral nervous system to the central nervous system, in this case from the wall of the gut to the brain.(3) Usually people start to have symptoms of Parkinson’s disease between the ages of 50 and 60. But in certain case start earlier. The symptoms of Parkinson’s disease first may be notice is tremor which means shaking or trembling. And these may affect the hands, arms, or legs. It is one of the most common signs but not everyone has it. Also, not everyone with a tremor has Parkinson’s disease. The tremor often starts only one side of the body or just one arm or leg. In addition, Parkinson’s affects the stiff muscles all through the body, so it causes problems like trouble swallowing or constipation. In the later stages of Parkinson’s disease a person may have fixed expression trouble speaking and other problems. Some people lose mental skills. (1) A dopamine Dopamine is a chemical signal that transfers information from one neuron and the next neuron. It released the signals from the first neuron and it floats into the synapse (the space between the two neurons) to the second neuron. The receptors bumps the signals down to the receiving neurons. The dopamine interested in many different important pathways and it known as the mesolimbic pathways which starts with cells in the ventral tegmental area in the midbrain.(2) The dopamine plays numbers of roles in human and other animals. It controls many functions such as movement, memory, pleasurable reward, attention, sleep, learning, mood, inhibition of prolactin production, and behaviour. The increase and deficiency of this dopamine chemical is cause of several disease like Parkinson’ disease. In the brain, part called the basal ganglia regulates movement. Basal ganglia in turn depend on a certain amount of dopamine to function. The action of this occurs by dopamine receptors D 1-5. Th e deficiency in dopamine in the brain may become delayed and uncoordinated the movement and other function of the body. (3) The dopamine is important neurotransmitter in the brain substantial part of the overall dopamine in the body is produced outside the brain by mesenteric organs. The production of dopamine within the central nervous system, depend on the dopamine biosynthesis. There are two steps of dopamine biosynthesis takes place in the cytosol of CAergic neurons and starts with hydroxylase of L-tyrosine at the phenol ring by tyrosine hydroxylase to produce DOPA.(4) Stem cell The stem cell have potential to develop into many different cell types in the body during early life and growth. In many tissues they serve as a sort of internal repair system, divided without limit to replace other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the ability either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell and other cells.(5) The stem cells are featured from other cell types by two important characteristics. First, they are capable of renewing themselves through cell division, sometimes after long periods of inactivity. Second, under some physiologic or experimental conditions, stem cell can be become tissue- or organ-specific cells with special functions. In certain organs, such as the gut and bone marrow, they regularly divide to repair and replace worn out or damaged tissues. In addition, in other organs, such as the pancreas and the heart, stem cells only divide under special conditions. (5) Scientists primarily worked with two types of stem cells from animals and humans: embryonic stem cells and non-embryonic somatic or adult stem cells. In 1981 Scientists discovered ways to derive embryonic stem cells from early mouse embryos nearly 30 years ago. In 1998 the detailed study of the biology of mouse stem cells led to the discovery. After that method to derive stem cells from human embryos and grow the cells in the laboratory. These cells are called human embryonic stem cells. The embryos used to studies were created for reproductive purposes through in vitro fertilization procedures. When they were no longer needed for that purpose, they were donated for research with the informed consent of the donor. Researchers made another breakthrough by identifying conditions that would allow some specialized adult cells to be reprogrammed† to assume a stem cell-like state in 2006. This new kind of stem cell, called induced pluripotent stem cells (iPSCs). (5) The Stem cells are important for living organisms for different reasons. In the three to five days old embryo, called a blastocyst, the inner cells give rise to the en tire body of the organism, include all of the many specialized cell types and organs such as the, lungs, heart, skin and other tissues. In certain adult tissues, such as bone marrow, brain, and muscle, the adult stem cells generate replacements for cells that are lost through normal injury, or disease. The stem cells make new potentials for treating diseases such as heart disease and Parkinson disease. However, much work remains to be done in the laboratory to understand how to use these cells therapies to treat disease.(5) Research on stem cells continues to advance about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms. The stem cell research is one of the fascinating areas in contemporary biology.(5) The laboratory of human embryonic stem cell The protocol of the laboratory that culture the stem cells must contain special equipment use to avoiding the contamination during make the HESC culture. The equipment that are use a CO2 incubator, that cannot use the detergent to clean use 70% of ethanol to get the best result to control the contamination. Used a biocontainment hood to control of microorganisms. A microscope with phase contrast optics to see the cell and colony morphology. A refrigerator 20ù and freezers 80ù.Use the liquid nitrogen freezer to store the stocks of HESC and feeders. Also, need small water bath 37 ù to thawing the cell that are frozen.(6) Feeder culture The feeder culture use to growth of HESC. It prepare primary fibroblast that come from the CF-1 mice. The CF-1 mouse embryonic fibroblasts give the optimal growth of HESC without differentiation and recommended for many reason such as function well making feeder, available and cheaper. (6) The methods culture HESC The first thing need to culture the HESC is good feeder. Human embryonic stem cell should be passaged when the colonies reach size 300 to 500 cells. The plate should be passaged large culture of colonies. The cell always passaged to the plate of feeder cell less than seven days. (6) The materials that required for passaging Human embryonic stem cell are ESC medium, 15 ml centrifuge tubes, calcium/magnesium free PBS, collagenase type IV, cell scraper ,10 cm plates and 0.1% gelatin.(6) The procedure: Table show the methods of passaging HESC adopted steps only but I create the table (6) Growth of the HESC To growth the human embryonic stem cell transfer cell from preimplantation stage embryo to the culture dish. The cell will grow on the culture dish and will spread and divided on the surface of the media. The culture dish contain the mouse embryonic cell which provide the nutrients into the culture media to growth the cell. However, researcher now devised to grow the embryonic stem cells without mouse feeder cells to avoid the risk viruses that can transfer from the media to the human. (5) The test use to identify embryonic stem cells in the laboratory. There is no standard test approved yet to the scientists who study human embryonic stem cells. However, the laboratories that grow the human embryonic stem cells use different types of test such as: Growing and subculture of the stem cell for many months to make sure the health of the cell. Use techniques to determine the presence of transcription factors that produced by undifferentiated cells. These are two important transcription factors Nanog and Oct-4. The both factors help the genes to turn on and off to make maintain the stem cell to undifferentiated and self-renewal.(5) The GMP There are many challenges to use the stem cells for replacement therapy. However, the good manufacturing practice (GMP) is quality assurance system that use to make sure the product of stem cells is good and safe to use for treatment. The GMP in human embryonic stem cell culture required several components for good clinical practice. First, the culture or the feeder media that use in the laboratory must be reach to standard of GMP. Second, the inner cell mass of the blastocyst and passaging of the cell. Final, all components of the culture and cryopreservation media should validated to the GMP system. (7) The ethical issue surrounding the use of embryonic cell need be carefully controlled. In UK human embryonic stem cell can collected from left over embryos produced as part of vitro fertilisation. This can done under strict UK guidelines from Human Fertilisation Embryology Authority and only in the early stage embryos can be use in research up to maximum of 14 day of development.(8) The power of stem cell In 1980, the researcher take stem cell inside the developing embryos and growth in the laboratory to make the human embryonic stem cell. However, the adult stem cell are extremely powerful and easier for researcher to make embryonic stem cell and can converted into any type of cell in the body. But there is risk that the stem cell may grow uncontrolled in the body which cause to formation of tumour.(8) Scientist in Japan worked to make stem cell from normal adult cell in 2006 and this called induced pluripotent stem cell (iPS). This iPS cell in the future may use to make for the patient own cell and it be safe from other factor the affect the patient. The researcher attempted to treat the cell that are die from the nervous cell by make experiment on rat and mice. It show improvement to develop of dopamine that make replace of nervous cell. The researcher can measure the increase of dopamine neuron function in striatum of the patient by using positron emission tomography that make image of the brain.(5) Many researchers believe that embryonic stem cell could be excellent source of dopamine neurons because can grow in culture dish and make into any type of cell after long time in culture. Now, the dopamine neurons have been generated from the Human embryonic stem cell. One study research use the special type of companion cell with specific growth factors to promote the differentiation of the embryonic stem cell through several stages into dopamine (5) References Webmd.com, (2014).

Hannibal Barca :: essays research papers

Hannibal Barca was born in 247 B.C. in the city of Carthage, which was located in modern Tunis, or the northern tip of Africa. His father, Hamilcar Barca, was a great Carthaginian general of the army who fought in the First Punic War between Rome and Carthage, which the latter lost. At a very young age, Hamilcar made Hannibal promise â€Å"eternal hatred towards Rome† (Lendering, 1). At around age nine, Hannibal accompanied his father on an expedition to gain a hold in Spain. During this time was when Hannibal probably gained most of his military knowledge that helped him greatly later in life. When Hannibal’s father and older brother died in 229 and 226, Hannibal was elected commander-in-chief of the Carthaginian army. About ten years later, Hannibal, acting on his promise to his father, attacked the city of Sagantum in Spain, which was controlled by the Romans. This attack led to the start of the Second Punic War between Carthage and Rome.   Ã‚  Ã‚  Ã‚  Ã‚  Even before the war started, Hannibal knew what he was going to do. Since Carthage had no navy, there was no hope of going directly from Carthage to Italy over the Mediterranean Sea. Hannibal thought up a dangerous but ingenious plan. In order to get to Italy over land, Hannibal and his army would have to travel from Carthage-controlled Spain across the Alps and into the heart of the enemy. Hannibal left in the cold winter of 218 B.C. with 50,000 infantry, 9,000 cavalry, and 37 war elephants. While crossing the Alps, â€Å"Hannibal’s force suffered greatly from the elements and the hostility of the local tribesmen† (Beshara, 3). By the time they reached Italy, after only fourteen days, over 9,000 men had perished along with most of the elephants, but this number was soon replenished after 14,000 northern Gaul rebels joined Hannibal’s army. This group of 60,000 men proved superior to the Roman forces, and after at least three recorded major vic tories, the Roman senate was exasperated. An army of 80,000 Roman soldiers was sent to stop Hannibal’s army of now 50,000 once and for all. In July of 216 B.C., the Romans engaged the Carthaginians in â€Å"the neighborhood of Cannae on the Italian east coast† (Lendering, 2). Greatly outnumbered, Hannibal realized that he would have to win by strategy, and that is exactly what he did. As the two lines met, Hannibal’s cavalry gained the flanks and, moving up the sides, attacked the rear of the Roman line.
