All living things

All living things use some way to survive and defend themselves. Frogs use their skin in many ways for these reasons. So how do frogs use their skin, color and poison to survive and defend themselves? In this paper you will learn how frogs use their skin to live, survive and defend themselves. Frog skin is thin and naked. It has no scales, no hair, and no feathers. However, the skin of a frog is critical to their survival. Through it, they both drink and breathe. They also use their skin to absorb all the moisture they need through their skin because they do not swallow. Although frogs do have lungs, they rely on the extra oxygen they absorb through their skin, especially when theyre underwater. Frogs must keep their skin moist. Otherwise, oxygen cant pass easily through their skin and they suffocate. Frog skin secretes a mucus that helps them keep moist. Even so, their skin tends to dry out which is why they usually stay near bodies of water. They rely on dew for moisture or burrow themselves underground in moist soil. Although they rely on their skin for a lot of purposes they do rejuvenate themselves by shedding their skin once a week. This process consists of a lot of twisting, bending and stretching to loosen the skin. Once the frog has loosened ! it enough it pulls the skin over its head like a sweater and usually eats it. I have been describing simple and logical reasons for the importance of frog skin. However, there are more reasons to make it all the more fascinating. In frogs, pigmentation or skin color depends on the presence of specialized cells and the resulting optical phenomena. These cells are differentiated from the so-called neural crest during the stage when the brain and the spine are being formed and then migrate to the surface of the skin. The evolutionary history of the biology of pigmentation may be dry material, but it is the basis for the dazzling ...

No Culture Is an Island Essays

No Culture Is an Island Essays No Culture Is an Island Essay No Culture Is an Island Essay No culture is an island means, cultures aren’t bound to say in one area as it’s stuck on an island. It influences people to people, community to community, country to country. All human interaction is influenced to some degree by the cultural, social, and physical settings in which it occurs. It’s given that culture powerfully influences thoughts, emotions and behaviors. Every person’s culture is his own mindset that they develop during childhood grooming and socialization.Social Change, every culture has its own lifestyle the way people dress, what roles genders have, what role children have and what they do in their leisure time. But the culture is influencing social change on other parts of the world too. As it’s the 21stcentury media helps people in other parts of the world to observe and most of them feel attracted to because it’s new to them and adopt in their culture.Example Jeans was a western culture gradually with time passing by rest of the world got familiar with it and now it’s been adopted in almost every culture. Arts, by arts I mean music, theatre and their creator/performers. They have a big influence on people all over the world. If they are really famous some people set celebrities as there role model and start adopting their cultures. The world come to knows what other cultures exist through Arts. Hollywood had a big role in changing cultures all over the world.The influence of Musicians and Actors is effective and brings a change in their fans culture really quick. Technology, now a day’s same technology is being used all over the developed and developing countries. Again I would say media helps spread the news that what types of technology is out there and rest of the world tries to obtain it and adopt it, because no one wants stay behind in the matter of technology and the people who adopt the new technology helps them compete with the world.

Data Analysis - Research Paper Example The period under study is from 1997 to 2001, a five year period. The basis for this particular study is the fact that the company promises to replace the copiers if the service personnel are not in a position to rectify or resolve service complaints within a period of 72 hours and the service commitment given to the customer is that the non-functional or problematic copier would be replaced within a period of 48 hours. Exhibit 1 below shows the sales figures for the five years under study across the different geographic locations and the annual growth rate. The sales across were achieved by deploying extensive sales force in the marketplace. One of the principles that were used to increase revenues was to increase the sales force. The following table and graphs give the number of sales personnel during the study period. While sales is one of the parameters for increasing the revenues, it was found that the commitment of replacing un-serviceable photocopiers was eating directly into the bottom-lines of the company. The number of complaints received is captured as under - Exhibit 4 and graph 4: While measuring the effectiveness of the sales personnel, similar data is captured for service personnel.

Peyton Budget and Analyzing Assignment Example | Topics and Well Written Essays - 1250 words

Peyton Budget and Analyzing - Assignment Example The sales budget for Peyton Approved shows that the company forecasts sales to be $1,080,000 for the quarter ending September 2015. To cover the sales and the required ending inventory, the company needs to produce 60,000 units. That would require 27,380 units of raw material at a cost of $212,195. The total labor requirement is 30,000 hours at a cost of $480,000. While the budget estimate for direct material for the period is 36,320 units, the actual amount of direct labor is 31,000 units. The budgeted price per unit of direct material is $7.75. It is also the actual price. Given the difference is only on the number of units of direct material, the direct material price variance is zero. As for the direct material efficiency variance, the company records a favorable efficiency variance of $41,230. That gives a favorable total material variance of $41,230. There was no material price variance as the budget price and the actual price were the same. As for the favorable efficiency variance, there may have been several causes. As the actual production shows, there was less direct material usage than the budget estimates. That may have been a result of efficiency in utilizing material in the production process. The procurement process may also have contributed to the favorable efficiency variance. Where there is purchase of high quality material, there would probably be no wastage and the production may use up less material than the estimates (Nobles, Mattison and Matsumura, 2014).

Computer Forensics And Crime Investigations Information Technology Essay

Computer Forensics And Crime Investigations Information Technology Essay With the progression of time and advancement in technology, our digitized nation has and will become more dependent on computers as we use them in our daily lives whether it be at school, work, or for personal use. By evaluating past trends it is safe to calculate a rise in crimes using computers. Today criminals put a strain on computer forensic examiners, because there are few crimes that are committed without the involvement of a computer or any other computing device of some sort. Today with computer hardware and software becoming more sophisticated and portable along with wireless technology this broadens the definition of computers, but for this research a personal computer is the extent of the subject. With technology constantly evolving and with the definition updating what is to be considered evidence, this is why proper training and education is necessary. This is why it is imperative to examine crimes where computers play a role in a crime and it is essential to find any potential evidence located on the digital media. For a person charged with an offense, their charge in the case can be weakened if the investigation fails to find any such evidence. This is why it is imperative to create, build, and improve a national standardization and certification for the computer forensics field. The Statement of the Problem The definition of computer forensics may vary slightly depending on the authors on the subject. One of commonly known definition refers computer forensics as the acquisition, examination, and reporting of information found on computers and networks that pertain to a criminal or civil investigation (Kessler, 2005). Computer forensics is becoming increasingly important due to growth of crime-rates involving the use of computers and the Internet. Although such a trend is difficult to control completely, computer forensics technologies and applications provide necessary tools to law enforcement and other agencies to assist in crime investigations. Computer forensics is effectively used in solving cybercrimes; however, its use reaches far beyond just that. As many criminals engage in more sinister crimes-such as murder, kidnapping, sexual assault, and terrorism-also maintain incriminating information on their computers, recovering damning evidence from their computers often provides law enforcement crucial discoveries during investigations. There are numerous real-life crimes that were solved by use of computer forensics, and the significance of computer forensics continues to increase as technologies develop. However, computer evidence does not always provide solid traces of information necessary to prosecute a criminal due to computers volatile and virtual nature of data storage. Proper processing of computer evidence is essential to establishing credibility of evidence collected from computers and other peripherals, and it is computer forensics experts responsibility to ensure that the evidence is valid, uncorrupted, and unq uestionable. Why research this topic During a computer investigation, the computer system that is suspected to have to possible evidence must be properly handled by a professional. They investigator must create a copy or true image (bit stream) of the original media, which would be inspected later in the process for crucial evidence. When inspecting the copy the investigator will look for specific expressions or key words to establish any vital digital evidence that exists or has been deleted. The types of incriminating digital evidence could be many such as: racial discrimination, sexual discrimination, stock fraud, blackmail, and numerous others. To help promote fast turnaround time computer forensic professionals have the aid of commercial software packages like X-Ways Forensics, Encase, and several other commercial and open source utilities. Unfortunately, the consequences of not following precisely these steps can lead to the lost of evidence itself, and therefore it is important to create, build, and improve the m ethods of performing well-organized searches in order to trace evidence. The need for a current study in the computer forensics field is important for the future of not only the computer forensics field, and law enforcement, but for the legal system and everyone else who uses a computer. Today in our digital nation, we are becoming more dependable on technology and its many branches of devices. This has lead to make investigators ask themselves what type of computer crime has happened, what is considered evidence, and how to handle it. Methodology As time and technology progresses computer forensics is a very important factor on the war in computer crimes in our nation. Most reading suggest in order for computer forensics to properly be considered by the courts as a scientific discipline there has to be proper education, training, and testing for adequate certification. The time frames from the readings were 2000-2010, but a majority of them were from 2004 2006. There has been improvement in recent years to develop a national unified approach in undergraduate and graduate programs. Hypothesis Computer forensics is a relatively new field and discipline in the private sector compared to other forensic sciences. Computer forensics is the science of acquiring, preservation, identification, extraction/retrieving, and documentation of computer evidence that has been processed by electronic means and stored on a computer without altering any of the data in the process. With our rapidly evolving improving technology this has lead the definition of computer forensics to be interchangeable with digital forensics, which expands the definition to include PDAs, cell phones, and other portable devices. When conducting a forensic investigation with computer evidence; the investigator must perform particular procedures to guarantee successful evidence collection. The evidence collected can be useful in civil disputes, criminal cases, computer system break in, recover data, and human resources/employment proceedings. As our homes, workplaces, and organizations become more incorporated wit h the aid of information technology and the Internet; we also have to take into consideration the human element as a factor. This is why current research is needed to tailor programs for computer forensics to keep up with advanced criminals. background In order to prepare for the future we need to look in the past and try to figure out how we got here and how to fix some of the problems. Technological progress is like an axe in the hands of a pathological criminal. (Albert Einstein) As technology changes and the words that explain it there is the unchanged motives and emotional needs that drives the criminal behavior. With this in mind we need to understand the intentions of the inventors for the computer and the Internet. Before the invention of personal computers and the Internet these technological tools were used exclusively for scientific leaders and the military; which were located in either military bases or major university campuses. Half a century ago, the technology we use today might have seemed like science fiction. The first general-purpose electronic computer was the ENIAC, Electronic Numerical Integrator And Computer. The intentions of the creators were to design a machine for mathematical power for computing. The Un ited States Department of Defense began funding of ARPA (the Advanced Research Projects Agency) and in 1969 the Internets first long distance electronic communication was made. The intentions of the creators were to create an instrument to guarantee an infrastructure between military installations. The goal of computer forensics is to recover and preserve digital evidence and to understand as much information regarding to the data as possible. The need for a computer forensics examiner is after the fact electronic information has been altered, deleted, or stolen in a computer crime. As with any other types of crimes it is a fact that the criminal leaves behind traces of their activity and these traces are the smoking gun that leads to prosecution in the court system. A computer forensics specialist is more than a computer expert; they must know how to effectively perform complex evidence recover procedures. These procedures include: data duplication/preservation, data seizure, data recover, document searches, expert witness services, media conversion, computer evidence service options, and miscellaneous services. A computer forensic examiner must follow federal guidelines for data seizure. One course of action allows a representative to examine and duplicate designated documents or data compilations that may include evidence, and it is The Federal Rules of Civil Procedure. When data is duplicated or preserved the main concern is that data must not be altered in any way. Data recover is performed using dedicated tools for computer forensics to safely recover and analyze evidence. A document search is the ability to understand storage technology and perform a search with speed and efficiency. Media conversion is the ability to find and cross-examine data from the source or unreadable device, extract data and convert it into readable formats. Part of being a computer forensic specialist is to at times be an expert witness, and explain complex technical processes in an easy to understand manner. Some level of services that should be offered is on-site, standard, emergency, priority, and weekend s ervices. Other miscellaneous services include analysis of computers and data, on-site seizure in criminal investigations. Also an advantage is the ability to work on both PC and Mac O/S and a fast turnaround of time. Overview of Computer Crime Today criminals usually are one step ahead of law enforcement agencies and they have the knowledge to use computers to their gain, and they have the ability to cover their tracks. Since technology is constantly changing definitions are quickly becoming outdated as new definitions expand new offenses to computer crimes. However, computer crime can be generally categorize into four categories and they are criminal activity that involves using a computer as an instrument to commit a crime, criminal activity that has a computer as a target, such as hacking into, criminal activity when the computer was unintentionally part of the crime, and crimes frequently associated with the use of computers. With this new definition computer crimes in 2009 have increased 22% from 2008. The computer as an instrument of a crime When a criminal uses a computer as an instrument in a crime we can think of it as when a burglar uses a crowbar or lock picks as in instrument to enter a house. For this research, when a computer is used as an instrument of a crime there objective is to obtain data to commit fraud, theft of service, harassment and other illegal activities through a network by copying data rather than deleting. Theft is when a criminal unlawfully takes and carries away property or service without the permission of the owner. The property and service can range from personal/private information, financial information, security information, human resources information, internet access and trade secrets. With the stolen property or services the criminal can reproduce false identification, copyright material, and distribute child pornography among other types of crimes. Another use of a computer is by writing letters or e-mails to make threats, harassments, or stalk individuals. Computer as a target When a criminal targets a computer as part of the crime they launch an attack on computers or networks trying to deny service by denying the rightful user access to their own computer system or data. Another attack could be to damage or alter the computer system or data by browsing through valuable information stored or saved on the computer. When a computer is vandalized this also is considered as a computer as a target, because valuable information stored in the computer is denied to the rightful owner. The computer as incidental to a crime In a crime scene a computer can be seen as a subsidiary tool to a crime when criminals use the computer to simplify their transactions. These crimes could happen without technology, but the computer assists the criminal in their transactions which might include child pornography, money laundering, leads to other crimes and other criminal information. This computer crime evidence could have names of victims, associates, clients, and perpetrators personal information. Crimes associated with the prevalence of computers Technology advancements have created new targets of conventional crimes and the targets are on the industry. This includes academic property, software piracy/counterfeiting, copyright infringement of computer programs, black market computer equipment, counterfeit equipment, identity theft, and programs, and theft of technological equipment. The most common use of this crime is piracy or the violation of copyright infringement of commercial software COMPUTER FORENSICS SERVICES Today on television there are shows that portray crime scene investigation while using computer forensics, and they give the audience a little glimpse into the world of computer forensics. When in reality computer forensics is meticulous work, but the shows leave out all the details of the process. Computer forensic today based on a theory of trace evidence, and this theory is build upon the development of forensic science. One of the motivating factors in the development of forensic science was by 20th century forensic scientist Edmond Locard, and his theory was called the The Locard Exchange Principle. The Locard exchange principle states there will always be an exchange when two items come into contact, and that the contact(s) will bring something into the scene of the crime and leave behind something in the scene, therefore leaving a trace of evidence. Although trace evidence might be small yet important information found in a computer, it alone is not enough to make a case. Traces evidence can might be the smoking gun that leads to a successfully win in a court case. No matter how well the criminal tries to cover up their tracks, in todays society with computers hooked up to a network or wirelessly leaves traces of stored data on a computer to be found. This is where the skills and services of a computer forensics specialist will come in handy. This section is where computer forensic specialist and self proclaim computer experts get divided into separate groups. The field of computer forensics is vital to law enforcement agencies, because the procedures to protect and present evidence in court are followed by the requirements of the judicial system. There are plenty of computer experts who know how to search through files, point, click, copy, and make directory listings, but a computer forensics specialist does more than this. A computer forensics specialist must be familiar with and understand in detail how files systems are created, accessed, deleted, and changed. With training and experience a computer forensics specialist understands the methods and techniques for securing and acquiring evidence without altering it in a legal manner. Acquisition Just as any other type of evidence, digital evidence also comes across some difficulty. So why go through the trouble of collecting it? It is because if we dont try to figure out who committed the crime, why they did it and how, then we will never be able to stop them or anyone else from committing a crime again. This is why trying to recover all possible deleted files is crucial. Areas to look evidence can be in the hard drive, page files, temporary or swap files, and unallocated space. When collecting evidence in this step no changes or modifications to the evidence must be made or else the evidence will be considered inadmissible. Preservation When a proper warrant is issued the ability to protect data from a recovered system must be protected and unaltered in any way. The computer forensic specialist should pay close attention to this step in trying to avoid the notorious Murphys Law. To avoid this mishap at this point in time an exact duplicate copy should be made in order to preserve the best evidence, the original evidence. One of the most effective ways to back up is the use of bit stream image back-ups. This method copies and preserves all data enclosed partition, logical drive, and physical drive in the hard drive. Another idea to think about when preserving digital evidence is where to save it, and that depends on the investigator and the organization they work for. Analysis The person conducting and analyzing the evidence in the investigation but be able to guarantee that the result of an conclusion came from the evidence, and were not in any way a part of contamination or error. One area that the computer forensic specialist can control is making sure hardware and software are working properly. They can also check to make sure their equipment is up to date with updates, verify licenses, and know how to use the equipment. A vital process to conduct analysis is creating a hash value. The hash value is created with software to produce a unique value, like a digital fingerprint, produce a mathematical value. Documentation This process is crucial in the field, because if one mistake is made in reporting of evidence, then any other evidence could be questioned. Once the evidence has been indentify everything encountered with the use of a digital camera, video camera, or pen and paper or a combination of two. Once this is done, then all evidence must be labeled and any devices attached to the computer along with ports and wires connected the two. In case a computer forensics investigator is testifying in a court case, then the documentation process will help the investigator jog their memory. In conclusion, following these steps is crucial in computer forensics because it builds stronger methods within time. Experience and training of software can result in better search techniques to build a better and faster turnaround time. There is a need for a current study to identify future trends and concerns in judicial system on the subject of digital evidence and computer forensics. With the data gathered on future trends schools and computer forensic field can educate and train future forensic investigators with current and proper techniques to keep up with criminals.

Inner Peace- religion Essay

Analyse how the individual is guided towards acheiving inner peace in TWO religious traditions. (18/20)Inner peace is defined as an internal quality of calmness and security which puts the mind at ease and fills the adherent with a sense of tranquility and assurance. For adherents to Christianity and Islam, inner peace is an inevitable and hugely rewarding consequence of genuine faith. It is developed rather than striven for, through a unique combination of personal, communal, scriptural and doctrinal means. Christians believe that inner peace is obtained by being in a close relationship with God. This involves accepting the gift of love from God and accepting that grace is given and not earned. Christianity teaches God lives in the hearts of His people, all are made in His image and likeness, therefore Peace lies within. The Bible states: â€Å"Grace and peace be multiplied unto you through the knowledge of God† (1 Peter 1:2). Christianity seeks to bring adherents to recognit ion; all who love God will gain peace, by living a life modeled after Jesus Christ. Essentially, faith in God instills within the adherent a sense of security and meaning conductive to the development of inner peace.The Christian tradition indicates the primary way of focusing inner peace and improving efforts at peacemaking is by returning to the Gospels and the sacred writings of Christianity. The reason for doing this is to renew the Christian’s knowledge and understanding of Jesus as the model peacemaker. Throughout the New Testament, Jesus’ teachings are echoed by recalling his words and actions: â€Å"Peace I leave with you, my peace I give to you† (John 14:27). The individual is guided toward inner peace through the Bible, which facilitates greater familiarity with the nature of God and acts as a source of practical, ethical and spiritual guidance. Christianity provides guidance for many forms of personal prayer using such means as scripture, writings from religious figures and various forms of meditation and contemplation. Centering prayer provides guidance for the Christian to go to their ‘inner’ place and there encounter God. This sustains the adherent in everyday life and contributes to a sense of peace and wellbeing. In being thankful and expressing gratitude to God, believers experience inner peace. The World Community for Christian Meditation proclaims: â€Å"Meditation and prayer is a practice that can bring peace, not only to individual meditators, but also to the whole world†.A significant means in which Christianity guides  adherents to find inner peace is through the concept of forgiveness. Jesus of Nazareth taught his disciples to pray:â€Å"Forgive us our trespasses as we forgive those who trespass against us† (Matthew 6:12). Through the death of Jesus, forgiveness is available to the repentant sinner, allowing them to have peace with God which is the very foundation of ‘inner peace’. Failure to forgive others leads to stored anger and resentment. The Protestant tradition places the emphasis on each person having the responsibility of speaking directly with God, who will grant absolution. It is the acceptance of the gift from God of forgiveness or wrongdoing which is the obtaining of inner peace for the Christian. Islam teaches that inner peace may only be found through complete submission to God’s will, which is primarily achieved by adherence to a prescribed set of guidelines for living. â€Å"In remembrance of Allah do hearts find satisfaction† (Qur’an 13:28). Acceptance of the will of Allah not only removes the fear and anxiety about the future, but concentrating on God can protect humanity from being overwhelmed by all aspects of life such as greed and fear which destroy inner peace. Jihad is central to this life of submission. Greater Jihad is the concept relating to the ongoing struggle to make oneself and one’s community ‘ perfectly’ Muslim. It embodies peace on a personal level, working through the individual and their role in the community.Inner peace is only possible when the Five Pillars are lived in faithful obedience to God’s will. Obligatory prayers, known as Salat, remind Muslims of Allah’s closeness to them. The Qur’an states: â€Å"Perform the prayer for my remembrance† (Qur’an 20:40). Attention is drawn repeatedly to Allah, marginalizing earthly distraction in order to devote more fully to the divine. Sawm or fasting, reminds participants of those who do not have enough to eat or difficulty living. In being reminded on these things, Muslims are reminded to place too much importance on material goods. They are reminded to place their trust in God for provision of food, which can help them to achieve inner peace. Hajj involves the spiritual, mental and physical journey from one’s normal place of living to Makkah. In the midst of a million pilgrims, the individual Muslim experiences the inner peace of the Ummah. Sufism is an Islamic theology that began to develop in the first century of Islam. Sufism stresses that the traveler on the spiritual path must first abandon himself or herself to the will of God and then only will God’s peace enter their heart. A frequent  Sufi proclamation is: â€Å"There will be no peace until there is inner peace†. The Australian Centre for Sufism and Irfanic Studies offers courses in spiritual development and Sufi psychology that aim to bring people closer to God and inner peace. One of the centre’s aims is to make people more aware that self-centeredness can be a barrier to spiritual enlightenment.Therefore, the religious traditions of Christianity and Islam present several means in guiding the individual to achieve inner peace. It is through the belief systems, actions and thoughts of these religious traditions, that those individual adherents can learn how to achieve inner peace and develop an understanding of peace so that it may be en acted.

Under What Circumstances May a Person Be Criminally Liable for a Failure to Act?

General principleThere is no general liability for failure to act under the common law of England and Wales. A crime can be committed by omission, but there can be no omission in law in the absence of a duty to act. The general basis for imposing liability in criminal law is that the defendant must be proved to have committed a guilty act whilst having had a guilty state of mind. The physical elements are collectively called the actus reus and the accompanied mental state is called the mens rea.Liability for omissionsThe general rule is that there can be no liability for failing to act, unless at the time of the failure to act the defendant was under a legal duty to take positive action. ‘’Unless a statute specifically so provides, or †¦.the common law impose a duty upon a person to act in a particular way towards another†¦ a mere omission to act cannot lead to criminal liability’’.(R Vs Miller[1983]1 All ER 978.) A positive duty to act exists in the following circumstances:(a)Duty arising from statute Liability for failing to act will be imposed where the defendant can be shown to have been under a statutory duty to take positive action. A leading example of such a case is provided by the children and Young Persons Act 1933, which creates the offence of wilfully neglecting a child. Hence by simply failing to provide food for the child or failing to obtain appropriate medical care a parent could be held criminally liable for any harm that results. (Greener Vs DPP[1996] The Times, Feb. 15,1996).(b)Duty arising from a ContractWhere a person is under a positive duty to act because of his obligations under a contract, his failure to perform the contractual duty in question can form the basis of criminal liability. (R Vs Pittwood [1902] 19 TLR 37).
