Network Security Planning - Research Paper Example Over the year network infrastructure has always been suffering major threats and immeasurable attacks of the data panel. The following has been established as the major threats to the network infrastructure: In order to secure network infrastructure one must secure and manage the access of such infrastructure devices. Compromising with the infrastructure devise access, compromises the management and security of the entire network. This calls for the establishment of critical and suitable controls necessary to curb unauthorized invasion to the infrastructure devices. Network infrastructure devices aims at providing a wide range and different variety of access protocols. This includes asynchronous and console connections, In addition to protocols based on remote access such as HTTP, Telnet, rlogin and SSH. Therefore, every infrastructure device should be skillfully configured and reviewed to ensure that only allowed access procedures are enhanced and that they are thoroughly protected. Enhance confidentiality of data- protect all the sensitive data stored from copying or viewing. Protect all the information in a communication channel from session hijacking, sniffing, and man in the middle attacks. Cisco safe architecture, like any other network security system, is not immune to limitations. However, it has successfully developed threat mitigation and detection programs readily available on Cisco security agents, Cisco firewalls, Cisco network admissions control, and Cisco IPS and web safety appliances. In addition, these devices alerts and generate information centrally gathered and correlated using the Cisco security monitoring, analysis and response system which recognize the source of threats, envisage the attack route, give the possible suggestions and sometimes optionally implements the response actions. The visibility of Cisco IPS reduces many instances of false positives thus allowing for dynamic quarantine impositions of unsecured

Various Factors in the Preparation and cooking of Fruit and Vegetables Essay Example for Free

Various Factors in the Preparation and cooking of Fruit and Vegetables Essay Pilot Method 1. Use a syringe (or Measuring Cylinder for measuring equal amounts) and pour out 10ml of DCPIP (Solution used to detect Vit.C) into a small beaker. 2. Using a separate Syringe, draw up 10ml of solution 0.1% Vitamin C 3. Slowly add the Vit.C into the DCPIP solution beaker, swirling around a few times. (swirling helps solutions to mix) 4. Continue to add the Vit.C until DCPIP turns a permanent straw colour. 5. Note the amount of Vit.C it took to change the colour of the DCPIP. 6. Repeat steps 1-5 5 3 times and take an average.

Compared with the other Juices (excluding juice one as it is pure Vitamin C) it takes less of this Juice to turn the DCPIP straw coloured (an average of 13ml). In comparison to the others there was not much difference between them all. The Pure Orange Juice with Pure Mango took an average of 14ml to turn the DCPIP straw coloured. After doing some research on the Vitamin content on different fruits, it was seen that both mangos and grapefruits, Mangos and Oranges are excellent vitamin C sources. Fruit Latin name mg vitamin C / 100 grams mg vitamin C per average size fruit/slice* Ranking Grapefruit Citrus paradisi 34 44* excellent Mango Mangifera indica 28 57 Excelent Orange Citrus sinenis 53 70 Excellent * The values are for one whole fruit, however not many would eat a whole medium sized watermelon at a sitting, so for these larger fruit the value is for a slice, a slice being, very generally, about an eighth of a medium sized fruit, or a quarter of a smaller fruit. In the particular case of lemon and lime, the slice value is juice of one wedge. For a few small fruit, such as Kei apple, the ranking is adjusted upward where the fruit mg/100 gram analysis shows it has large amounts of vitamin C, but the small size of the fruit gives it a lower per fruit vitamin C content. You are likely to eat more than one at a serving. In the case of tiny fruit, like red or black currants, a lot more, but probably still only 20-30 raw fruit, especially if they are a bit acid.. The chart states that Mangos have a higher Vitamin C level than Grapefruits implying that the results should have been the other way around with the Orange and Mango Juice having more Vitamin C present. However it could be due to the preparation process that has taken an effect on the amount of Vitamin C present. Vitamin C is a particularly fragile vitamin and is easily destroyed when in contact with oxygen in the air or if it is exposed to light. The vitamin C content of sliced, cut or bruised fruit and vegetables diminish rapidly when such foods are left standing. Freshly squeezed orange juice will lose half of its vitamin C content by the next morning. Vitamin C is one of the least stable vitamins, and cooking can destroy much of this water-soluble vitamin from foods. Vitamin C is a weak acid and is stable in weak acids. Alkalis, such as baking soda, however, destroy ascorbic acid. It is also easily oxidized in air and sensitive to heat and light. Since it is contained in the watery part of fruits and vegetables, it is easily lost during cooking in water. Evaluation The experiment went very well in that that the investigation was carried out in a safe and efficient way. The investigation was planned to produce an out come showing the strength of Vitamin C concentrations in different Juice types. This was done and a conclusion was gathered showing what was being looked for. In hindsight it was seen that the calculation could have caused problems in the reliability of the results. All the calculation were done with one main equation. However if there was any point were the calculations were not dome properly it would mean that the given numbers would not have been correct. Also, the calculator did not round up decimals; therefore figures given would have been dependant on if the numbers were rounded up or not. Making sure that the same method was used at all stages could have rectified this. This would have ensured that all the figures were reliable. Another problem that could have caused results to be unreliable is the readings that were taken. The syringes that were used had markings that went up in 5s. Its possible that the reading were not done very accurate and not made at their actual point. If this problem were consistent all of the readings would have been inaccurate. By having the same person doing the readings and also having used a syringe that has more reading points would have made them more accurate in that the individual points would have been easier to read. Another possible problem that was seen was the fact that the aim was to look for colour changes. It would not have been able to come to a sure conclusion of what was straw colour and what was not. It would have not been able to come to a sure mark of straw coloured. There would not no real solution to this problem as it would be dependant on the person. The only solution that could minimise this problem would be to have the same person making the judgments, as their perception of Straw coloured would be the same. Apart from the above points the investigation was went well and was carried out smoothly. The team were able to conclude the investigation with the use of gained figures and reactions.

Peer Pressure in Gang Violence

Peer Pressure in Gang Violence One of the Gang Peer group pressure is a major problem for teens now days, caused by pressure require by others and their wanting to fit into certain groups. The negative peer group is being named by the society as gangs. Adolescents associated with these groups feel they gained prestige. Nevertheless, not all peer group pressure has negative influence, like academic and athletic achievement. (Ayres Nalebuff, 2005) Based on studies, most teens/adolescents think that joining a group gives them popularity with their peers. The average teen feels pressure either from the school, peers, or parents; thus enticing the need to belong to groups. Oftentimes, they get involved in violence, alcohol or drugs users, and sex. Studies will prove that high school students give more time with their friends than with parents or other influential adults. Teenagers who get involved with delinquent friends shun themselves away from good or straight kids and choose to fit in to their own kind. Nowadays, majority of families are headed by single parents, most of them mothers, who work extra jobs. Single parent are spending little time with their teens, thus leaving them victim to peer group pressure. Research shows that peer group pressure may lead to delinquent behavior among teenagers, which includes criminal acts such as motor vehicle theft, burglary, and robbery and others (Cabot, M. (2007). Peer pressure can manipulate a person into smoking, drinking, or doing drugs and other things that is harmful to his/her body. Nevertheless, peer pressure can also be supportive by influencing someone to do the right thing instead of wrong. For instance, a person can be a model to his/her friends and let them know he/she wants to do right and he/she wants to change how he/she acts or what he/she was like. Some people struggle because they are depressed by what they have done or what people done to hurt their feelings in the past (Healey, J. 2007). Peer Pressure is said to be responsible for teenagers behaviors starting from choice in clothing to drug usage. A study shows that the outcome of peer pressure on teenagers behavior may be highly overestimated. This study was published in Addiction (Vol. 91, No. 2), adds to a increasing body of research that implies peer pressure is a weaker factor in adolescent behavior than many had believed. Much emphasis is not given on peer pressure, dont discuss or do not look hard for evidence of other factors. Going back and try to critically examine the importance of peer pressure. Researchers did studies over a twenty year span to find that peer pressure was easily blamed for teenage behavior but never examined. Other issues such as family life, economic background, environment, and biological tendencies all may be as important as or even more important than peer pressure in determining behavior. Teenagers who smoke tends to choose peers who smoke as friends and children with the same habit s have a tendency to hang together. Peer pressure can be least factor in the use of drugs and other habits related to adolescent life, but nonetheless peer pressure is a factor that influences drug use among teenagers. From ages twelve to nineteen is a stage in a teenagers life that determines what kind of adult he or she will become. This stage of adolescence, known as the formative years, is the subject of deeper study and research to establish why adolescents are vulnerable to the phenomenon called peer pressure. Disturbing number of incidents of teenage drug use, pregnancy and teenage suicide is the best reason to fuel the need for such research. Probably because as children they are taught the importance of having and maintaining friends or maybe they dont feel that they can talk to their parents or teachers when problems arise. Or perhaps simple reason as wanting to rebel against the pressures placed on them as youths. Because adolescents spend their time either at home or in school, it is within these confines that the answers to adolescents behavior lay. In other words, family and school can sometimes cause adolescents to give in to peer pressure because of an overemphasis on the importance of social adjustment, a lack of interest or communication on the part of the parents and teachers, and the unrealistic expectations that these entities create. Even if the reason for attending school is to receive an education, it also gives children with a medium through which they can develop relationships with other children that eventually turn into friendships. Their capability in forming friendships can be traced back to even the pre-school years and its importance emphasized by eager parents who want their children to fit in at school. Interactions with friends or other peers are crucial for the development of a mature morality. Almost all would agree that social interaction is essential but at times parents are guilty of over-stressing this importance. For Example, the birthday parties where every child in the neighborhood was invited to come regardless of whether or not they were actual friends. The need to socialize children also happens in the classroom at school. The classroom represents not only an educational ground but a powerful social context in which the psychological adjustment of children and adolescents can be influence d. Teachers promote social interaction by assigning exercises that necessitate working in pairs or groups. Besides, when a teacher notice a child playing alone, they will persuade him or her to join the other children failing to notice the possibility that the child might have preferred to be alone. Therefore, from an early age, children are taught to value the importance of social interaction and this value remains in them as they move into the adolescent years. Result of which is that adolescents value their friendships deeply and in some cases more so than their relationships with family members. This accounts for the adolescent not being able to deny their friends for fear of losing the bonds that they have formed and is the cause of their greater vulnerability to peer pressure. Having experienced peer pressure, during my adolescent years in order to fit in, because its not easy being the only one doing something different. Oftentimes, I feel worried Ill be picked on if I dont go with the crowd, or I lose my friends. Other times I do stuff because I think my friends will like me more, or because my gangs are doing it, so it seems normal. Both close friendships and wider friendship groups have provided opportunities for me to join them, and that was to smoking. Until I realized that I was into smoking for a longer period of time and hard to quit. But I asked myself if I was doing what I really think is right or just giving in to my peers pressure to impress my friends and my gang. But as I grow older, I was faced with some challenging decisions. Some of them dont have a clear right or wrong answer. Meaning I dont really know if what I was doing was really good for me. I realized that making decisions on my own was hard enough, but when people got involved and tried to pressure me one way or another, it was even harder. People, who were my age, like classmates and gangs. They tried to influence how I act, to get me to do something I do not really want to do. But because I want to stay in the gang, I was pressured to do things and sometimes overdo them to impress my gang. The peer pressure during my adolescent years was really something I had to deal with, maybe even adults too. I underwent a peer mentoring program, which matches older youths with younger ones. The former provide the latter with guidance, advice, and all forms of support I need to be able to meet challengers of my adolescent life. The older youth do not only serve as mentors but as role models to the younger ones like me. They were not perfect but having been through the same stage and most likely, the same problems, predicaments, and challenges in their homes, school and community; they are in the position to provide friendly advice, positive influences, attention and moral support to me and other younger teens. I learned to choose my friends wisely. Focus on developing firm friendships with people with the same values and ideas like me. Even having one friend who will back me up when I want to go against the group will help. I learned to be strong and just go with what I know is right. Good friends respect my individuality and I stood up for what I believe in and learned to respect myself more. Giving in to peer pressure tapers off later in life. If adolescents realize that social interaction is important but only to a certain point, then they will have the strength to say no to their friends. Similarly, if parents and teachers somehow found a way to better communicate with their children and students respectively, these adolescents would most likely come to share their feelings with them and not rely so much on their peers for feedback. (Havelin, K. 2000) And lastly, if parents and teachers became aware of the unrealistic expectations they place on teenagers, the result would be a decrease in conflict as well as a decrease in the number of adolescents who feel the need to rebel through conformity to peer pressure. In other words, examining the ways in which family and school cause adolescents to give in to peer pressure leads to a resolution of the causes. What is the overall result? Adolescents have a healthier sense of the meaning of friendships, they have an alternative other than peers to whom they can turn to and they are freed from any unrealistic expectations that they themselves cant understand. But most importantly, they become less susceptible to the traps of peer pressure, thereby, giving in to peer pressure is narrow (Kaplan, 1983). Learning about human development should give you a deeper understanding of the many different pathways humans can take as they grown and develop through the lifespan. It is important to understand child life from the childs point of view. This means understanding how the way we see and make sense of the world is affected by cognitive-developmental factors. The same applies to understanding adolescents and adults or all ages. Physical, cognitive and social capacities are intertwined. A change in how we understand the world has implications for how we interact with others which in turn has an impact on physical development. Conversely, playing games provides experiences with groups that foster new understandings about the physical and social universe. Development is profoundly affected by social context (culture and social institutions). Our beliefs about the nature of development what is normal and what is not normal are anchored in a particular social, historical and cultural conte xt. Understanding human development can help you better understand your own life experiences and life course. It can foster enhanced self-understanding and personal growth. Beneficial societal change is possible and individuals and groups can change social institutions and policies for the better. Understanding human development deeply and in context can help us better appreciate human wisdom and human fallibility. This, in turn, can help us become more creative, innovative and effective teachers. Peer pressure can be described as a positive or negative reaction that occurs when one is influenced by certain people or peers. Peer pressure is constantly surrounding us. One can first be introduced to peer pressure at a very young age and young people can be influenced easier then mature adults. I believe family members, friends and religious institutions have the strongest influence of peer pressure on society. But from past experiences, friends have the strongest influence on teenagers. With the proper guidance and right choice of friends, one will not have any trouble with lifes difficult decisions, and will hopefully, do the right thing. Ayres, I., Nalebuff, B. (2005).

The Influence and the Role of the Jewish Community in Ancient and Conte

The Influence and the Role of the Jewish Community in Ancient and Contemporary Turkey Antiquity A Jewish community has existed in the land that is modern day Turkey for many centuries. In fact, many important figures of the Old Testament lived in Turkey during at least part of their lives. Abraham was born in Ur of Chaldea, according to the Old Testament, which is believed to be the Turkish city Sanhurfa (located close to the Euphrates River) (G 3). It is also believed that Abraham lived in Harran in the 18th century BC. Jacob sought refuge in Turkey when he was escaping from his brother Esau and his well is still found there today. Noah and his family ran aground on Mount Ararat (Agri Dag), which is located in eastern Turkey near Dogubayazit. Noah's descendents would become the Hittites who ruled central Anatolia (modern day Turkey), the Assyrians, and Abrahams ancestors among others (Burke 1). Due to multiple invasions of Palestine, many Jews were forced into exile. These Jews, and subsequently all Jews residing abroad, or "dispersed", were referred to as the Jews of the Diaspora or simply the Diaspora. In 560 BCE, Babylon conquered Judah and a relatively small number of Jews were exiled. Some would eventually return to Jerusalem but others built centers of Jewish culture throughout Mesopotamia (Burke 1). The remnants of Jewish settlement have been discovered in the Aegean Region that date to the 4th century BCE confirming Josephus Flavius' records of Aristotle having met and exchanged ideas with some Jewish people in Asia Minor. Other Jewish settlements have been found in various parts of modern Turkey that date to the third century BCE most notably the remains of an ancient synagogue in Sardis (Guleryuz ... ...exis.com.

The play centers around Blanche DuBois, who has been fired from her teaching job, and arrives unannounced at the small two-room apartment of her pregnant sister, Stella Kowalski. Stella, who lives with Stanley, her rough and domineering husband in a poor section of the French Quarter in New Orleans, welcomes her older sister. Although Blanche portrays the part of an aristocratic young woman, in actuality she is nothing more than an aging Southern belle who has come to tell her sister that she has lost everything, including their childhood home, Belle Reve. Stanley’s suspicious nature causes him to assume that Blanche is keeping money from Stella and immediately puts him at odds with her. Stanley’s nature is violent and Blanche sees him as "common" in every way, so advises her sister to strike out against him. Stanley overhears this and cannot forgive Blanche, realizing her as a threat to his marriage. The two argue about everything, causing Stella to choose be tween them. The main problem comes when Stanley unearths Blanche’s sordid past. Mitch, Stanley’s gentle friend, has gradually been seeing Blanche from the time of her arrival. As a last resort to save herself from Stanley and poverty, Blanche expresses her hopes to marry him. Blanche’s past however, is tainted due to her promiscuity and her affection for young boys. She blames this on her ex-husband, whom she found lying with another man and soon afterward killed himself. On her birthday, Stanley informs Mitch of her many affairs, causing the deterioration of their relationship and killing Blanche’s hopes for the future. This causes a scene between Stanley and Stella, and as a result, she goes into early labor. The final conflict comes when Stanley and Blanche are alone in the apartment waiting for Stella to come home from the hospital. Stanley decides to take advantage of the situation and when he expresses his intentions, Blanche tries in vain to defend herself. The scene ends with her brutal rape by Stanley.

Examination of Clinical Psychology Essay

Clinical psychology is a broad science that involves psychologists ensuring the mental well-being of a patient. Its focus is diagnosing, treating, and if possible, averting psychological disorders. The field of clinical psychology applies to every demographic from young children to the elderly, families or individuals, and one’s socioeconomic status is not a factor in whether he or she should receive treatment. Clinical psychology deals with a broad range of specialties, including individuals who have been diagnosed with disorders such as schizophrenia and bipolar disorder or those who are coping with personal issues, such as being fired from his or her place of employment or going through a divorce. Psychologists in this field offer patients the opportunity to voice his or her frustrations while helping the patient to understand and manage their situations in a healthy manner. Clinical psychologists are skilled in using numerous methods intended to help patients, all depending on his or her area of expertise. History of Clinical Psychology Although established as a legitimate field in the late 1800s, the study of psychology has been dated back as far as 2500 B. C. In those days, approaches to examining mental health included the supernatural, holistic, religious and medical perspectives. Greek physician Hippocrates, also known as the father of ancient medicine, played a considerable role in the development of psychology. Hippocrates developed the theory of humors, which states that four humors, or bodily fluids, are the key to good health. These fluids were black bile, yellow bile, phlegm, and blood (Plante, 2010). Too much phlegm in the body will make an individual tired and lethargic; too much blood in the body would cause irritability; too much black bile causes melancholy, and too much yellow bile causes anxiety. Not unlike present-day doctors, Hippocrates believed a healthy diet and exercise could aid in preventing or treating these symptoms but he was also a promoter of blood-letting, which essentially meant the patient would be bled dry with the intention of returning the four humors to their natural state. Greek philosopher Plato strongly believed that the soul has free will and the body will perform as the soul wills it to. He felt that mental illness is caused by something malfunctioning in the part of the soul that controls reason and an individual’s lack of self-awareness were the cause of the symptoms. Aristotle maintained a scientific emphasis and felt that certain distinct emotional states including joy, anger, fear, and courage impacted the functioning of the human body (Plante, 2010). Another Greek physician, Galen, took all of these perspectives and created one of the most influential medical programs in the history of psychology. Galen shared the same beliefs as his predecessors concerning the theory of humors and blood-letting, and although some of his ideas were imperfect, he was able to make great strides in medicine with his rationalizations of poor health and its origins. With the Middle Ages came a different type of explanation of mental illness. During this time, many people thought the reasoning behind abnormal behavior had more to do with supernatural forces rather than the body or soul. There were some, however, such as Saint Thomas Aquinas and Bishop Nicholas Oresme, who did not believe that mental illness had anything to do with supernatural forces and correctly speculated that these afflictions were caused by physical or mental abnormalities. In the 16th century, Swiss physician Paracelsus went as far as to reveal that he believed the movements of the stars had an effect on one’s mood and developed more civilized treatments for the mentally ill. Subsequent to Paracelsus, Juan Luis Vives and Johann Weyer switched the focus of what causes mental illnesses from the soul and supernatural forces to behavior, and like Paracelsus, advocated for humane treatment of patients. The Renaissance era and the 19th century brought along with them the re-emergence of medical treatments, leaving supernatural and religious approaches behind. It was during this time psychologists learned that affected organs in the body could cause illness and possibly lead to death. Ultimately, the discovery of such scientific findings would usher in a new era of clinical psychology and render Greek ideologies a thing of the past. Psychology officially became a valid field in 1879 when German physician Wilhelm Wundt opened his laboratory of psychology at the University of Leipzig in Germany. Wundt conducted many experiments in his laboratory, with a focus on human reaction. His intent was to study behavior in order to acquire a better understanding of the mind and its workings by using scientific methods. Four years later, Lightner Witmer opened the first sychological clinic in Pennsylvania (Plante, 2010). During this time, many professionals in the field were more interested in experimental psychology and were against the idea of human behavior being applied to clinical situations. Despite misgivings concerning the new field, clinical psychology was able to flourish and has come a long way since earlier opposition. Evolving Nature of Clinical Psychology The evolution of methods of diagnosis and treatment in medicine has been characterized by the gradual accumulation over many centuries of a large body of objectively recorded observations (Routh, 2000). With technology ever-changing to fit the modern standards of today, so too does the field of clinical psychology. New scientific breakthroughs are made constantly in regard to human behavior, the brain and how they relate to one another. To correspond with these new empirical-based findings, clinical psychology evolves its methods as well. A key factor in this evolution is the immense effort put into attempting to understand the human mind, its abnormalities, and where they originate from. Modern clinical psychology is the epitome of scientific progression as it improves its methods of learning as much as possible about the evolving human mind. Research and Statistics in Clinical Psychology Research and statistics are an essential element to clinical psychology. Research is used to verify or refute a theory, while statistics are used to prove the validity and reliability of a theory. The collected empirical results aid researchers in creating helpful approaches to advanced treatments for those who need it. With these findings, psychologists are able to help individuals with a broad spectrum of issues, from relationship problems to more serious matters, such as depression or the death of a loved one. Statistics are applied to determine how essential the gathered data is to the research conducted. The two disciplines combined assist researchers in developing more useful approaches in the treatment of patients. Differences between Clinical Psychology and Other Mental Health Professions Some of the differences between clinical psychology and other disciplines are education requirements, work duties and salary. Individuals who desire to become clinical psychologists must obtain either a Doctorate of Philosophy (Ph. D. ) or a Doctorate of Psychology (Psy. D. ). Those who choose the Ph. D. are focused on the research of psychology and those who choose the Psy. D. are more interested in working in a clinical setting. The work duties of a clinical psychologist include assessing an individual’s mental health and trying to find the most appropriate treatment for him or her by analyzing the patient’s surroundings and interpersonal relationships. Regarding salary, psychologists can earn anywhere from $45,000-150,000 annually, depending on how long he or she has been in practice and how successful that practice is (Grohol, 2011). To become a social worker, one must obtain a Master’s degree (MSW) to work in a school or mental health environment. Social workers help individuals or families to deal with issues such as domestic strife, social problems, or child abuse just to name a few. Depending on the subfield, the salary of a social worker varies. Psychiatry is a field that is often confused with psychology. Though there is not much of a difference between the two, psychiatry deals with the treatment of the mind while psychology deals with the science of the mind. To become a psychiatrist, one must obtain a medical degree followed by an additional four years of training in a medical facility. The one huge difference between psychiatrists and psychologists is psychiatrists have the authority to prescribe medication to his patients as well as psychotherapy. Psychiatrists may earn between $66,000-180,000 annually (Healthcare Salary Online, 2010). Like clinical psychologists, school psychologists must also obtain a four-year undergraduate degree. As the title suggests, school psychologists typically work in school settings evaluating students and creating school plans to fit the student’s needs. However, school psychologists are not only limited to working inside schools. They may also work in private practice, providing consultations for education-based companies. The salary for this field differs, depending on the area. The average annual salary for a 190-day contract ranges from $47,880. 00 to $67,070. 00, while top salaries can exceed $100,000 (National Association of School Psychologists, n. d. ). Conclusion To sum up, the field of psychology has come a long way since its roots in 2500 B. C. Thanks to physicians like Hippocrates, Plato, Wundt, and many others who were able to pave the way for psychologists of today, many people are able to reap the benefits and receive the help that is needed. Technology is ever changing, and with it comes the evolution of high-tech approaches to analyzing and treating the human psyche. Although all of the disciplines under psychology may differ somewhat, they all have the same goal, which is to assist in complying with the necessities of the human mind to impart a continuing aptitude to survive.

What accelerates and counteracts global warming?

Global warming is the worst challenge facing the world in the 21st century. Since the second half of the 20th century, there has been sudden increase in global temperature leading to global warming effect. Increased human activities and natural activities have contributed to increase global warming.Global warming has had various negative effects in the world including melting of polar ice and rise in sea levels, changes in weather pattern with prolonged drought and torrents of rain, disappearance of species, and many others. One of the main factors that have contributed to global warming is release of green house gases to the atmosphere. Release of gases like carbon dioxide, carbon monoxide, nitrite oxide, and others has contributed to green house effect leading to global warming.Although green house gases has been cited as the main source of global warming, there are other minor sources which over the time has led to   substantial increase in global temperature. However, there are alternative factors counteracting global warming effects which include aerosols and soot, solar variation, and many others.Alternative causes of global warmingThe most common indicator used to indicate global warming is the change in average global temperature at the near earth’s surface.   Between 1860 and 1900 it is recorded that the earth surface temperature increased by  Ã‚   0.75oC which is approximately 1.35oF.Since 1979, the global temperature at the lower trosphere has recorded an increase of more than 0.22oC. Before 1850, it is believed that temperature was relatively stable for more than two thousands years and therefore it is the increase in human activities especially industrialization that has led to increase in global temperature. According to recent records, 2005 was recorded as the warmest year ever since the scientific world started keeping reliable records.The main factor contributing to increased global temperature has been release of green house gases to the atmosphere (Pierce and Adams, 2009). It is believed that gases like carbon dioxide, carbon monoxide, nitrite oxide, nitrogen dioxide and others leads to green house effects which increases global temperature.While green house gases contribute to global warming effects, it is believed that there are factors which had previously been thought to cause global warming but counteract global warming effects.Although their contribution may be minimal and difficult to notice, these factors can led to substantial cooling of the earth over a long period of time. Let us look at some of these factors including aerosols and soot which counteract global warming and solar variation which may accelerates global warmingAerosols and soot Aerosols and soot contribute to global cooling through global dimming. This is an effect in which there is gradual reduction in the range of direct irradiance to the earth that greatly counteracts global warming effect.This phenomenon, which has been studied s ince 1960 evidence that global dimming, can contribute to cooling of the earth over a long period of time.   Global dimming is mainly caused by aerosols which are produced through volcanic activities and other emissions like sulfur dioxide (Pierce and Adams, 2009).Aerosols produce a cooling effect through increase of reflection of some of the incoming sunlight.   Ã‚  Through scattering and absorbing of the solar radiation, aerosols have also been shown to have indirect effects on the net radiation budget.For example sulfate aerosols have been found to form cloud condensation nuclei which lead to clouds having smaller could droplets.   The formed clouds have been shown to reflect solar radiation when compared to clouds with fewer and large droplets.Soot can lead to cool or warm effect on the globe depending on its state whether airborne or deposition. Soot aerosols in the atmosphere absorb solar radiation thereby cooling the earth since solar radiation heats the atmosphere.Howe ver, soot deposited at the glaciers has been shown to heat the earth surfaces.   Aerosols have more pronounced effects in the tropical and sub-tropical regions especially in Asia.
