Determine the distribution of shear force, bending moment and stress Essay

Determine the distribution of shear force, bending moment and stress due to bending in simply supported beams - Essay Example to Identify the measurements to be taken, they should be variables and they both should be able to be measured at the same time (the measurements should be as specific as possible to reduce variation and increase the chance of higher correlation). The third part is to make 50 to 100 pairs of the measurement, ensure that the measurements are as steady as possible so as they do not interfere with the final figures. The next step will be to plot the measured pairs on a scatter Diagram, plot them to give maximum visual spread points; this may involve using different scales and making the axes cross at non-zero value. The last step is that the diagram will be seen and it should be interpreted and action taken accordingly Sketch graphs of shear force and bending moment distribution and validation of calculations by alternative checking methods, plus analysis of safety factor for a chosen material, incorporating referenced additional data, are required for M/D criteria. The strength of a correlation is determined in various statistical angles. It is in this aspect that this Correlation, which is represented by the value that fall between, values of -1.00 to +1.00. If the value is 1 positive or negative it means it is a perfect correlation, this rarely occurs as it means that when the variables both change with the same magnitude, while a correlation of 0 means that there is no relationship between the two variables. A correlation of .8, .9 or even .7 is a strong correlation and it means that there is a great relationship between the scores of one variables and the other, while a correlation of .2 or .3 is a weak correlation meaning that there are some relationships between two variables a but it is a weak one. Q1: Select a standard rolled steel I-section for the simply supported beam shown in figure below. Select an appropriate factor of safety and material strength. Include references for all source information employed. The self-weight of the beam itself may be

Computer Technician Essay Memory: Your memory does not store everything forever. The computer memory refers to computer components, devices and recording media that retain digital information. The computer data storage provides one of the core functions of a computer that of information retention. How a Computer Remembers: A computer has two memories, called RAM and ROM. ROM stands for Read Only Memory. It carries the information. The computer needs to carry out, it’s task, and it cannot be altered. It stays there even when the computer switch off. RAM stands for Random Access Memory or Read and Write Memory. This contains the information the computer needs to carry out the particular task you want. When you switch off the computer, RAM empties itself. You can save your work on CD-ROM, DVD ROM Disk, Floppy Disk, Flash Drives, etc. Storing Information: Each memory cells stores binary digits. It is easy to see that the size of computers RAM is important because the computer can only do the amount of work that it has room for. Computer Memory Memory Imagine that you are going to the park to play with your friends. You know the way because you have been there before. The route is stored in your memory. On the way, you meet someone and stop for a chat. If it’s not about anything important, you will probably soon forget. Your memory does not store everything forever. The computer memory refers to computer components, devices and recording media that retain digital information used for computing for some interval of time. The computer data storage provides one of the core functions of a computer, that of information retention. How a Computer Remembers A computer’s memory works in similar way. There are some pieces of information that need to be stored away. Others can be forgotten once the computer has worked on them. To separate the two types of information, a computer has two memories called ROM and RAM. ROM stands for Read Only Memory. ROM carries the information the computer needs to carry out its task. This information is built into the computer and cannot be altered. It stays there even when the computer is switched off, just as your memory of how to get to the park stays with you until you need it again. RAM stands for Random Access Memory, or read and write memory. This contains the information the computer needs to carry out the particular task you want it to do now. When you switch off the computer, RAM empties itself. You can save your work on CD-ROM. DVD ROM disks, floppy disks, flash drives, etc. Storing Information ROM and RAM are both made up of memory cells, Each memory cell stores binary digits. A chip may be able to store millions of bits. It is easy to see that the size of the computer’s RAM is important because RAM has room for it. With some computers, it is possible to add extra memory chips to increase the RAM.

How Number System Is Used In IT

How Number System Is Used In IT In this documentation I have discussed of how the application of number system is used in IT applications in both hardware and applications, operating system and in programming language. I have discussed about the use of base 2 in the 8 bit bytes form use with the operation for subnet. The use of hexadecimal form addressing memory and classless inter Domain Routing. There are number of different numbering system which is in use for the unique ability to represent different numbers. Binary, Octal, Denary and Hexadecimal are number systems that are used in different aspects Denary number is the most commonly used number system which is frequently used in daily life. Nevertheless each number system has associated benefits which are the reason that different number systems are used in different areas. Each of the number system has a fix number of representation of numbers which are used to represent the numbers like, say for example Binary numbers are represented by either one or zero, Octal numbers are represented by numbers from 0, 1, 2, 3, 4, 5, 6, 7 whereas Denary and Hexadecimal numbers are represented by the number of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0, 1,2. 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, respectively. Binary Numbers Binary numbers are mostly used when there are only two options available so if one is false then the other is true. Examples of binary system can be their usage to represent bits in a computer which can have only 0 or 1 value a switch in a electric circuit which can be either on (1) or off (0). Binary system is widely used to represent situations in everyday normal life as well for example for electronic gates in electricity circuits, false or true statements can also be displaced in terms of binary digits where 0 represents false and 1 represents true states. Denary Numbers Denary numbers are frequently used in everyday life in accounting, calendar systems, financial systems or daily routine counting. The main benefits of Denary number system is that they are easier to use as compared to other number systems and have more number to present different situations though Hexadecimal number system has more representations but that representation can include characters in them as well which makes them more difficult to understand and use as compare to denary system. Denary number systems are so frequently used that a person even do not need to have a formal education to know or use them. One of the reasons can be that it is frequently use in daily life accounting. Other number systems are used in more specified fields such as computing and hence would need to be learned. Octal Numbers Octal numbers are not that commonly used as compared to other numbers and are mostly used in computing graphics, text and famous operating system such as UNIX also uses octal numbers for their file protection system. Octal numbers have total of 8 unique representations which can be combined together to make more octal number representations. Octal numbers are difficult to understand for a normal person who has limited number of understanding about the number system. As after 7 different numbers are used to represent numbers from 7 onwards and hence they seem physically bit difficult to comprehend. The number system needs to use a subscript of 8 with is number to represented they are not Denary but octal number otherwise confusion can easily occurred. Hexadecimal Number System Hexadecimal number are used where there are more options which needs to be represented off and are mostly commonly used in computing to represent different memory locations. Since binary, octal and hexadecimal have representations which are powers of 2 (power of 0 in binary, 3 in octal and 4 in hexadecimal) hence that makes them more suitable to different situations, which require different number representations. They are positively contributing to the daily life and to the technology and logical world as well and needs to be understood properly if one needs to take advantage of such technology. Whilst the above gives uses of the binary, octal and hex number systems in different areas of IT and while some example are given the manager encourages you to research a wide range of examples for him to look at. Binary Number System used in ASCII table and IP Address Binary number system are also used in the ASCII table to represent different codes for different characters which then can be used into computing as well. ASCII number is more like a combination of binary numbers. Binary numbers are also used in IP addressing system again which is a combination of Binary number and are used in computing field. These IP addresses are of two different versions now one is known as IP 4 and other one is known as IP 6. These IP addresses are further sub divided into different classes such as class A, B and C where each class has a different number of hosts and network address. The ASCII character set, each binary value between 0 and 127 is given a specific character. Most computers extend the ASCII characters set to use the full range of 256 characters available in a byte. The upper 128 characters handle special things like accented characters from common foreign languages. In ASCII character set, each character is represented by 7 bits when stored in the computer and in an extended ASCII character set, each character is represented by 8 bits. Say for example: ASCII 0000000 represents NULL Similar the word HELLO if converted into binary using the ASCII to binary conversation could be represented as follows. 01001000 01000101 01001100 01001100 01001111(in decimal 72 69 76 79) Please refer an ASCII character table for further understanding of this conversion. ASCII Binary Conversation Octal numbering system for file protection in UNIX Every file or folder in UNIX has access permission. There are three types of permissions (what allowed to do with a file): Read Access Write Access Execute Access Permissions are defined for three types of users: The owner of the file The group that the owner belongs to Other users Thus, UNIX file permission are nine bits of information (3 types x 3 type of users), each of them may have just one of two values: allowed or denied. Simply put, for each file it can be specified who can read or write from/to the file. For programs or scripts it also can be set if they are allowed to be executed. Textual representation like -rwxr-r- It is used in UNIX long directory listings. It consists of 10 characters. The first character shows the file type. Next 9 characters are permissions, consisting of three groups: owner, groups, others. Each group consists of three symbols: rwx (in this order), if some permission is denied, then a dash -is used instead. For example -rrwxrr- 0123456789 Symbol in the position 0 (-) is the type of the file. It is either d if the item is a directory or l if it is a link, or - if the item is a regular file. Symbols in positions 1 to 3 (rwx) are permissions for the owner of the file. Symbols in positions 4 to 6 (r) are permissions for the group. Symbols in positions 7 to 9 (r) are permissions for others. r Read access is allowed w Write access is allowed x Execute access is allowed Replaces r, w or x if according access type is denied Numeric (octal) representation like 664 If a numeric representation is used (like in chmod-command, for example), then it is in the octal format (with the base of 8), and digits involved are 0 to 7. Octal format is used for the simplicity of understanding: every octal digit combines read, write and execute permissions together. Respective access rights for owner group and others (in this order) are the last three digits of the numeric file permissions representation. Example: 0644. Here the second digit (6 in the example) stands for rights of the owner, the third digit (4 in the example) stands for rights of the group, the fourth digit (4 in the example) stands for rights of others. The below tales show what numeric values mean: Octal digit Text equivalent Binary value Meaning 0 000 All types of access are denied 1 x 001 Execute access is allowed only 2 -w- 010 Write access is allowed only 3 -wx 011 Write and execute access are allowed 4 r 100 Read access is allowed only 5 r-x 101 Read and execute access are allowed 6 rw- 110 Read and write access are allowed 7 rwx 111 Everything is allowed According to the above table we can see that 1 stands for execute only, 2 stands for write only, 4stands for read only. To combine the permission you can simply add 1, 2 and 4 to get a needed combination. For instance, to get read and write permission, you add 4 (read) and 2 (write), thus getting 6 (read and write). To get read and execute permissions, you add 4 (read) and 1 (execute), this getting 5 (read and execute). Example: 755 on a file would mean rwx r-x r-w permission on the file. Simply convert the octal number to the binary equivalent and enable the permission where the bits are 1. 755 would mean 111 101 101 In addition there is one more octet representing the Set user ID, set group ID, sticky bit which works in a similar way. Octal digit Binary value Meaning 0 000 setuid, setgid, sticky bits are cleared 1 001 sticky bit is set 2 010 setgid bit is set 3 011 setgid and sticky bits are set 4 100 setuid bit is set 5 101 setuid and sticky bits are set 6 110 setuid and setgid bits are set 7 111 setuid, setgid, sticky bits are set Explain the use of binary in IP addressing for both V4 and V6? Use of binary in IP addressing for V4: Each IP in a V4 IP addressing consists of 32 bits. These 32 bits are divided into 4 octets of 8 bits each. An IP address is represented like this: 172.12.12.46. A computer can understand only binary values and therefore each IP is stored in binary. Each octet is represented as follows. For example if the value of the first octet is 128, it would be represented as follows: 128 64 32 16 8 4 2 1 1 0 0 0 0 0 0 0 Therefore an IP 128.128.128.128 would be stored as follows: 10000000 10000000 10000000 10000000 Use of binary in IP addressing for V6: While IPv4 allows 32 bits for an Internet Protocol address, and can therefore support 232 (4,294,967,296) addresses, IPv6 uses 128-bit addresses, so the new address space supports 2128(3.4 x 1038) addresses. This expansion allows for many more devices and user on the internet as well as extra flexibility in allocating addresses and efficiency for routing traffic. The IPv6 128-bit address is divided along 16-bit boundaries. Each 16-but block is then converted to a 4-digit hexadecimal number, separated by colons. The resulting representation is called colon-hexadecimal. This is in contrast to the 32-bit IPv4 address represented in dotted-decimal format, divided along 8-bit boundaries, and then converted to its decimal equivalent, separated by periods. The following example shows a 128-bit IPv6 address in binary form: 0010000111011010000000001101001100000000000000000010111100111011 0000001010101010000000001111111111111110001010001001110001011010 The following example shows this same address divided along 16-bit boundaries: 0010000111011010 0000000011010011 0000000000000000 00101111001110110000001010101010 0000000011111111 1111111000101000 1001110001011010 The following example shows each 16-bit block in the address converted to hexadecimal and delimited with colons. 21DA:00D3:0000:2F3B:02AA:00FF:FE28:9C5A IPv6 representation can be further simplified by removing the leading zeros within each 16-bit block. However, each block must have at least a single digit. The following example shows the address without the leading zeros: Javascript:CodeSnippet_CopyCode(CodeSnippetContainerCode3); 21DA:D3:0:2F3B:2AA:FF:FE28:9C5A Binary in describing class A, B and C IP addresses The class of the address determines which part belongs to the network address and which part belongs to the node address. All nodes on a given network share the same network prefix but must have a unique host number. Class A Network binary address start with 0, therefore the decimal number can be anywhere from 1 to 126. The first 8 bits (the first octet) identify the network and the remaining 24 bits indicate the host within the network. An example of a Class A IP address is 102.168.212.226, where 102 identifies the network and 168.212.226 identifies the host on that network. Class B Network binary addresses start with 10, therefore the decimal number can be anywhere from 128 to 191. (The number 127 is reserved for loopback and is used for internal testing on the local machine.) The first 16 bits (the first two octets) identify the network and the remaining 16 bits indicate the host within the network. An example of a Class B IP address is 168.212.226.204 where 168.212 identifies the network and 226.204 identifies the host on that network. Class C Network binary addresses start with 110, therefore the decimal number can be anywhere from 192 to 223. The first 24 bits (the first three octets) identify the network and the remaining 8 bits indicate the host within the network. An example of a Class C IP address is 200.168.212.226 where 200.168.212 identifies the network and 226 identifies the host on that network. Hexadecimal for addressing memory Memory addresses are displayed as two hex numbers. An example is C800:5. The part to the left of the colon (C800) is called the segment address, and the part to the right of the colon (5) is called the offset. The offset value can have as many as four hex digits. The actual memory address is calculated by adding a zero to the right of the segment address and adding the offset value, like this: C800:5 = C8000 + 5 = C8005 C8005 is called as the absolute or linear address of the memory. Similarly F000:FFFD can be computed to get the following memory address. F0000 + FFFD FFFFD or 1,048,573(decimal) The Segment: Offset addressing was introduced at a time when the largest register in a CPU was only 16-bits long which meant it could address only 65,536 bytes (64 KB) of memory, directly. But everyone was hungry for a way to run much larger programs! Rather than create a CPU with larger register sizes (as some CPU manufacturers had done), the designers at Intel decided to keep the 16-bit registers for their new 8086 CPU and added a different way to access more memory: They expanded the instruction set, so programs could tell the CPU to group two 16-bit registers together whenever they needed to refer to an Absolute memory location beyond 64 KB. Classless Inter Domain Routing Classless Inter Domain Routing. CIDR was invented several years ago to keep the internet from running out of IP addresses. The classful system of allocating IP addresses is very wasteful. Anyone who could reasonably show a need for more that 254 host addresses was given a Class B address block of 65533 host addresses. Even more wasteful were companies and organisations that were allocated Class A address blocks, which contain over 16 Million host addresses! Only a tiny percentage of the allocated Class A and Class B address space has ever been actually assigned to a host computer on the Internet. CIDR specifies an IP address range using a combination of an IP address and its associated network mask. CIDR notation uses the following format xxx.xxx.xxx.xxx/n where n is the number of (leftmost) 1 bits in the mask. For example, 192.168.12.0/23 applies the network mask 255.255.254.0 to the 192.168 network, starting at 192.168.12.0. This notation represents the address range 192.168.12.0 192.168.13.255. Compared to traditional class-based networking, 192.168.12.0/23 represents an aggregation of the two Class C subnets 192.168.12.0 and 192.168.13.0 each having a subnet mask of 255.255.255.0. In other words, 192.168.12.0/23 = 192.168.12.0/24 + 192.168.13.0/24

BEETHOVEN :: essays research papers

Ludwig Van Beethoven Born to a drunkard father and an unhappy mother, the young Beethoven was subjected to a brutal training in music at the hands of his father, who hoped that the boy would prove to be another prodigy like Mozart. Failing in this, the young Beethoven nevertheless embraced music and studied for a short time in 1792 with Franz Joseph Haydn in Vienna. Hailed as a genius and a master of improvisation at the piano, Beethoven soon made a name for himself, and by 1794 was known throughout Europe. He faithfully learned the Classical Viennese styles and traditions in music, and then proceeded throughout his career to completely revolutionize them. His earliest compositions reflect the classical restraint of Haydn and Mozart, yet there were always flashes of what was to come. The emotion he displayed while playing his own music was unheard of in his day, and the fiery intensity of his early Piano Sonata in C minor, known as the "Pathetique" is one of the first works in which Beethoven g ives vent to his own dramatic musical voice. By 1800, Beethoven had become aware of his advancing deafness -- surely a most horrible fate for a musician and unendurable to a composer. Agonizing over his fate, Beethoven contemplated suicide, but in the end embraced life, determined to go on composing, if no longer performing. Unhappy with his compositions up to that time and stating that he would now be "making a fresh start," Beethoven began composing music such as had never before been heard. His Symphony no. 3 in E-flat major, subtitle the "Eroica", was completed in 1804, and was almost twice as long as any symphony written up to that time. Taking the classical symphony as a starting point, it introduces more themes, more contrasts, more instruments, more weight and more drama than previously heard in the symphonic form. His sixteen string quartets span his creative life and developed from the classical restraint of the six "Early" quartets to the sublime late quartets which contain music of such personal pain and suffering, that one wonders if an audience was intended to hear them at all. The power of Beethoven's voice can be heard in the String Quartet no. 11 in F minor. Beethoven's musical ideas, the "themes" he used and from which he painstakingly constructed his works, were revolutionary for his day. The well-known opening motto theme of the famous Symphony no.

Prejudice and Racism at Our School :: Sociology Racism Prejudice Essays

Prejudice and Racism at Our School Racism...the belief that a particular race is superior to others; discrimination or prejudice based on race. Racism has been around for a long time and its effects have been seen a lot in the past few centuries: during the 1800s and earlier - in slavery, the Civil War, and slaves being freed; and then recently, during the 1900s - in the Civil Rights Movement. Everyone in the United States is supposed to have equal rights and not be discriminated against because of race, but sadly, that is not always what happens. Racism shouldn’t be around anymore, but it is, even in WCCHS. Sometimes it’s in the form of racist comments or racial slurs, and other times it’s in the form of "who hangs out with whom." Something needs to be done about this. I think that if there were more integration in school-related activities, then students of different races would learn to accept each other the way they are, and racism wouldn’t be an issue at WCCHS. As was stated, even though there shouldn’t be racism at WCCHS, there is. Although once in a while teachers might be involved if someone says something racist against them, most of the racism is between students. Although I don’t really see a whole lot of it and what I do see isn’t major, it is still there. Generally, Hispanics and non-Hispanics get along okay at WCCHS; a lot of the racism expressed in these two groups is just little things, such as racial slurs or mean comments about someone just because they are or aren’t Hispanic. To get a broader view on racism at WCCHS and why it occurs, I interviewed Karen Miller, a freshman of Polish and German descent; Gabe Antonio, a freshman of Mexican descent who knows both English and Spanish; and Mr. Sayner, a World Geography/Global Studies teacher of western European descent. Karen, Gabe, and Mr. Sayner all agreed on their definitions of racism. Gabe said that racism means â€Å"people saying bad stuff about other races and cultures,† Karen said that it means that someone doesn’t like another person just because of their race - they are prejudiced, and Mr. Sayner said it means â€Å"people judging someone else based on physical characteristics like skin color.† In all three definitions you see that people are basing their opinions of others on outward characteristics rather than finding out for themselves what they are like.

Creating a Plan of Positive Influence

When creating a plan for positive influence leaderships must focus on an array of characteristics of the employee. Organizational culture is important to the success of the employees and the company. ABC Tax Preparation Company wants to engage its staff in creating new revenue streams for the company. The company must identify traits demonstrated by employees to help create a profile of how individuals are motivated and open to improving his or her performance in the workplace. Research has shown there are several methods to induce motivation, performance, and job satisfaction (Yukl, 2006). This is a description on a plan identifying the implementation strategies to create, engage, and sustain employee in the workplace. The methods employers use to engage employees concentrate on attitudes, emotions, personalities, and values of individuals. In addition, the importance of diverse behavior and the influence it has on team collaboration and cohesion in the workplace is addressed. Objective ABC Tax Preparation Company is a small company attempting to expand its business through the implementation of new products and services. The company has a very small budget so it is important to maximize efforts to stay within the specified budget. The objective is to create a plan to influence employees to generate ideas on how to growth the company with new products and services. ABC Tax Preparation believes by engaging all employees to get involved in the brainstorming process will help the company with its goals and stay within budget. Providing employees with incentives persuades employees to go above and beyond to differentiate performance levels from its competitors (Love 2 rewards,2013). Outline of the Plan ABC Tax Preparation Company creates a profile of all employees to determine individual motivators, skills, creativity, strengths, and weaknesses. This is accomplished thought a series of test and skill determining exercises. First, the company implements motivational exercises and incentive to build moral within the company. Developing employee excitement to accept change and learning new task is a dynamic process important to moving a company in a positive direction. The next phase is getting to know the employees by determining his or her stressors, stimulators, and how individual measure success (Bass, 1990). The individual’s attitude, beliefs, experiences, ethics, and values are evaluated to determine if he or she align with the company’s visions and goals. Once these factors are determined, the company trains employees on conflict resolution and problem-solving techniques to help in the education process. This type of training is important because knowing how to deal with problems helps individuals to learn to deal with situations and create alternative solutions to solve issues. After employees are educated on techniques and other skills the company allows the creative process to occur and wait for the positive feedback. Once feedback is rendered the company will select the best ideas and start the implementation process to build new revenue streams for the company. How differences influence Behavior Diverse workforces interact with leaders, management, and subordinate in a distinctive way. Individuals coming from diverse backgrounds and cultures respond to direction and commands different from individuals in a familiar setting. Behavior has a direct effect on the way people perceive things and how different personality traits play a role on the performance of the individual (Robbins & Judge, 2007). Understanding and recognizing the relationship between variables influences behavior and aids in creating productive and motivated employees. ABC Tax Preparation Company employs a multicultural staff therefore there are different languages, beliefs, customs, and ideas management must consider when make decision. Leadership has to take into consideration when selecting holidays and other factors that all parties are represented equally. If employees do not feel, they are treated like the majority than the company is open for potential legal issues as a result. How plan influences positive change Motivation is a key component to creating an environment offering optimization of performance in the workplace. Change can be difficult for companies some employees embrace change and others fear change. Developing a plan to influences positive change requires understanding, educating, and motivating the employee. Brainstorming allows the employees to highlight creativity, education, and other skill-sets that will develop growth for the individual. Encouraging employees to engage in business activities builds moral and creates a collaborative work environment. Productivity is generated when employees are working together to achieve the same goals and objectives. Setting examples to show employees everyone is important and involved in the developmentally stages of the process give team-members a sense of worth, thus producing positive results. Making the employee understand the behavior presented determines the level of growth him or her may experience. Positive attitude can dive the individual faster than negative or unsure attitude. Conclusion ABC tax Preparation Company chooses to prioritize the engagement of its employees to aid in the implementation of a new revenue source for the company. Creating a plan to influence its employees to experience positive attitude toward changes is imperative to the process. A clear objective is outlined to determine what is needed to reach the goals of the company. ABC Tax Preparation Company outlines the details of the plan as proves motivated employees are productive employees when leadership creates cohesion in the workplace. Diversity in the workplace influences behavior by allowing individuals to express themselves and collaborated among each other to create innovative products and services for the company. The Initiation of a plan produces positive results for the company by setting a blueprint of how the company will use new ideas to generate new revenue streams for the company.

Manchild in the promised land

First generation blacks in New York had the unique situation of being in the urban life for the first time, having come from slave work conditions on southern farms, they brought their experiences of living as slaves, they brought their religion and they brought hope that life in the city would be different, that life would be better in the promise land.   As we seen in Manchild in the Promised Land, life in New York is hard, harder than the south in new ways that blacks could not have prepared themselves for. Poverty, violence, and prejudice followed them where ever they went in America, including New York.   Black children growing up in this urban setting are like weeds growing between the cracks in the pavement—they are hearty, they do what they have to do to survive.   The streets are their playground, their school and hope is only in the luck one has that they won’t get busted.   How did this lifestyle develop?   A number of factors, namely poverty and prejudice caused other problems to develop such as violence, child abuse, drugs, prostitution etc. Child Abuse One social ill that often stems from poverty is child abuse.   In the book child abuse is seen in homes such as Claude’s friend Bucky whose mother, who is on welfare, is in such a state of despair that she chooses her drink and gambling over feeding her own four children.   These children liked living in the child welfare house because at least there they had three meals a day and a place to sleep.   Of his friend Claude says, â€Å"Bucky was the only kid I knew who could stay out all night long and not be missed† (p 32). This clearly instilled in these youth the struggle to survive at all costs whether it be violence or stealing.   School also became something that hardly seems worthwhile when a child could be out â€Å"catting† on the streets and come home with food, money, clothes or other items when school only meant that you would probably get in trouble for something and get beat when you got home.   Claude doesn’t seem to realize the benefits of going to school, learning to read etc. until almost his high school years when the prison warden encourages him and believes that he could do well. Just as a master abused the slave, many a black parent abused their children under the pretense of â€Å"spare the rod and spoil the child,† raising them up with violence in their hearts from the start.   Black children in Harlem were to respect their parents and do what they were told or pay the cost. For punishment for his various crimes and school skipping, Claude is beaten progressively more seriously until his father resorts to hitting him with his fists because it seems that no matter what punishment Claude is given, he continues to get into trouble and his father is frustrated to the point of serious violence.   So from the age of six years old, violence is instilled in Claude as a means for upholding authority and for punishing wrong doing but interestingly enough, violence was not enough to make Claude respect his father and the day his father used his fists on Claude seems to be the day that Claude’s relationship with his father was severed. Violence Violence is a part of survival in Harlem.   One must defend their manhood, their reputation or fear losing important alliances with other men who help make street life livable.   In prison one must protect their rank of power, which is more clear cut than on the street. Examples of violence in the book include when Claude disowns his friend for allowing himself to be beat up by white men—to Harlem street youth this was the most disrespectful thing one could do to oneself. Big Bill, a man in Claude’s neighborhood, encouraged the kids to fight because he knew they needed to learn how to defend themselves on those hard streets.   Big Bill was preparing them for life, as he saw it.   In order to survive, Claude learned, you had to be a â€Å"bad nigger,† which meant that you had to be willing to do anything; you had to be willing to die.   One time when Claude was beat up over a quarter he said, â€Å"It wasn’t the value of money†¦ It was just that these things symbolized a man’s manhood or principles† (p. 256). Violence is used to keep racial segregation—Claude is raised being told that if he were to ever sleep with a white woman he would be lynched.   The police use violence to control violence.   Violence is also used by the everyday inhabitants of Harlem to protect themselves against the people who live the street life.   Claude caught a bullet in the stomach from a neighbor who was simply trying to keep their sheets from being stolen.   One man’s head was cracked open by a landlord for peeing in the hallway of his building.     Ã‚  The cycle of wrong doing seems to be perpetuated by violence; it cuts the psyche and makes a person grow callous to what has to be done to protect oneself and one’s belongings in Harlem or any poor urban ghetto. Role of Women Black women in Harlem are the lowest on the totem pole so to speak and are treated as if they were objects to own or use.   Women are considered to only exist to please men and men like Johnny, a pimp, treat women very badly in order to get what they want.   Claude’s own mother is helpless to control her son, simply ringing her hands and saying, â€Å"Boy, why you so bad?† (p 27).   In the case of Sugar and Melvin, Sugar must step up when her man decides that he is not going to struggle to survive in hostile Harlem but simply give up—she must take on a more important role in the relationship and lead the household. Drugs Drugs are another result of urban poverty in Harlem.   Drugs are an escape, a chance to make a quick buck.   Claude also said that drugs became associated with manhood, â€Å"the young cats wanted to take drugs because they used to listen to the way the junkies talked, with a drag in their voice† (p 261).   Many a black man in Harlem got caught in the web of Heroine, thinking that they were in control and selling it, the drug took control of them.   Pimp, Claude’s little brother, was just such a character and Claude spent a lot of time trying to show his brother that this just wasn’t the way. Religion Religion in Harlem harks back to the spirituals of the South.   Charismatic church services were held in old stores, apartments or where ever there is space to be had. The preachers, such as Mrs. Rogers, a jackleg preacher, have no formal training but lead their family and peers in a sermon and loud prayer sessions. Claude was very skeptical of his experience in Mrs. Roger’s church and for years later he remembered church as a place where, â€Å" somebody lined up a lot of kitchen chairs in a few rows, a preacher did a lot of shouting about the Lord, people jumping up and down until they got knocked down by the spirit, and Mrs. Rogers put bowls of money on a kitchen table and kept pointing to it and asking from more† (p. 27).   Claude believes throughout the book that religion is just another distraction, like a drug, to take one’s mind away from the suffering of hard living. Black Muslims in Harlem represented a little different form of faith that dealt with the issues of the ghetto by turning the philosophy of prejudice around so that the black man was the superior race and the whites inferior and according to Floyd Saks, â€Å"The time has come for all back men to rise up, band together and do something for themselves† (p 319).   These Muslim’s encouraged blacks to â€Å"buy black† to better the black economy.   Although Claude recognizes the need for change in his community he quickly sees that Floyd’s faith is simply exchanging one hate for another. Role Models The only role models that urban youth in Harlem seemed to have were negative ones.   Those that worked hard did not make enough money to survive or live well.   Those that seemed to have enough money and to have control over their life were the â€Å"street heroes† or the men who were able to lie, cheat and steal their living.   Claude was influenced by friends his own age such as Danny, who taught him how to steal from cash registers and skip school or Johnny who taught him how to hustle on the street. Claude in turn became a â€Å"street hero† and influenced his little brother Pimp who then ended up becoming a drug user.   The influence of siblings was such that Pimp was expected to live up to his brother’s tough reputation so he had to be a â€Å"bad nigger† and he had to get in as much trouble as possible to catch up to his brother’s years of street experience.   Claude has to beat up an older boy for his sister Carole’s honor in order to preserve his own as well as hers. Claude finds a positive influence only in the â€Å"comforts† of the regimented prison where everything is clearly laid out with purpose.   Mr. Papanek and Mrs. Coen are the only two people in Claude’s life who positively influenced his actions and helped him to realize that he was going no where doing the same things that got him in trouble before and got other men in trouble before and after him. Papanek kept telling people that, â€Å"Claude Brown is going to be a real success† and as a result, Claude believed it and made it happen (p 167).   Doing something different had not occurred to Claude before this or to other youth like him because there just weren’t any successful young black men to be found. Reverend James was a positive role model in the Harlem community that Claude sought to help his brother Pimp get off drugs and to find a track into college.   Claude respected Reverend James because he was as intelligent as Mr. Papanek but he was black and he lived in Harlem with the rest of those struggling to survive and had found a way to survive outside of the mores of the street.   â€Å"Reverend James is a pretty hip guy for a minister,†Ã‚   Claude admitted to Pimp and it is the Reverend’s ability to be â€Å"hip† that made him capable of really making a difference in the lives of Harlem youth (p 390). The Ghetto Mentality Poverty, violence, crime and the lack of any hope or any positive role models caused a â€Å"ghetto mentality† to develop that made people have low aspirations and to focus on the appearance of things such as making sure to have fine clothes rather than planning ahead with finances for the future.   Success was seen only in the street heroes: pimps and successful criminals. Tilto, Danny and Mac are good examples of boys with no aspiration to ever do anything else but hustle and hope for a quick showy success.   When asked what he was going to do with his life Claude’s friend Mac says, â€Å"I don’t know man. I guess I’ll deal drugs† like every one else in the neighborhood was already doing (p 237).   This ghetto mentality was re-enforced by the fact that men with a criminal record after the age of sixteen were unable to find gainful employment or become a successful citizen in society so there was a sense of, â€Å"why try, I can’t do anything about it now.† This mentality is broken only by the influence of someone like Claude, who everyone respects on the street and who decided to get out of the lifestyle and to find something more fulfilling in life.   The likelihood of urban youth to come in contact with a Mr. Pancheck, like Claude did is less likely than for them to be impressed to change by someone like Claude.
