Bond Energy Definition in Chemistry

Bond Energy Definition in Chemistry Bond energy (E)Â  is defined as the amount of energy required to break apart a mole of molecules into its component atoms. It is a measure of the strength of a chemical bond. Bond energy is also known as bond enthalpy (H) or simply as bond strength. Bond Energy Explained Bond energy is based on an average of bond dissociation values for species in the gas phase, typically at a temperature of 298 Kelvin. It may be found by measuring or calculating the enthalpy change of breaking a molecule into its component atoms and ions and dividing the value by the number of chemical bonds. For example, the enthalpy change of breaking methane (CH4) into a carbon atom and four hydrogen ions, divided by four (the number of C-H) bonds, yields the bond energy. Bond energy is not the same thing as bond-dissociation energy. Bond energy values are an average of the bond-dissociation energies within a molecule. Breaking subsequent bonds requires a different amount of energy.

One Percenters Motorcycle Gang

One Percenters Motorcycle Gang The term One-Percenters originated from the July 4, 1947, annual Gypsy Tour race sanctioned by the American Motorcyclist Association (AMA) which was held in Hollister, California. The  Gypsy Tour race,  which was the  pià ¨ce de rà ©sistance of motorcycle racing events during that time, was held at different locations across America and had been previously held in Hollister in 1936. The Event A location near the town was chosen again in 1947 partly because of  its  long relationship with bikers and various biker-related events that were held throughout the years, and also because of the welcome the   AMA  received by the town merchants who knew the positive impact it would have on the local economy. Approximately 4,000 attended the  Gypsy Tour  race and many of the riders and non-riders ended up celebrating in the town of Hollister. For three days there was a lot of hard-core beer drinking and street racing that went on in the town. By  Sunday,  the California Highway Patrol was called in armed with tear gas to help put an end to the event. The Aftermath After it was over, there was a record of about 55 bikers being arrested on misdemeanor charges. There were no reports of property being destroyed or of looting and not a single report of any local people being harmed in any way. However, the San Francisco Chronicle ran articles that exaggerated and sensationalized the event. Headlines like  Riots... Cyclists Take Over Town and words such as â€Å"terrorism† described the general atmosphere in Hollister over the holiday weekend. To top it off, a  San Francisco Chronicle  photographer by the name of Barney Peterson  staged  a photograph of an intoxicated biker holding a bottle of beer in each hand while leaning against a  Harley-Davidson motorcycle,  with broken beer bottles scattered on the ground. Life magazine picked up on the story and in the  July 21,  1947,  edition it ran  Petersons staged photograph   on full-page display titled, â€Å"Cyclist’s Holiday: He and Friends Terrorize Town.†Ã‚  Ultimately, to the dismay of the AMA, the image sparked both fascination and concern about the violent, unruly nature of the growing subculture of motorcycle groups. Afterward, films about motorcycle clubs with members depicting bad behavior began hitting the movie theaters.  The Wild One, starring  Marlon Brando, brought particular attention to gang-type behavior displayed by members of motorcycle clubs. The event became known as the Hollister Riot although there is no documentation that an actual riot occurred and the town of Hollister invited the race back, other cities across the country believed what the press reported and it resulted in numerous cancelations of the  Gypsy Tour races. AMA Responds It was rumored that the AMA defended the reputation of its association and member, with an alleged press release stating that, The trouble was caused by the one percent deviant that tarnishes the public image of both motorcycles and motorcyclists and going on to say  that 99 percent of bikers are law-abiding citizens, and the one percent are nothing more than outlaws.   However,  in 2005 the AMA denied credit for the term, saying that there was no record of any AMA official or published statement that originally used the one percent reference. No matter where it actually originated from, the  term caught on  and  new outlaw motorcycle gangs   (OMGs) emerged and embraced the concept of being referred to as  one-percenters. The Impact of War A number of veterans returning from the Vietnam War joined motorcycle clubs after being ostracized by many Americans, especially within their same age group. They were discriminated against by colleges, employers, often spat upon when in uniform and some considered them nothing but government-grown killing machines. The fact that 25 percent were drafted into the war and that the rest were trying to survive it did not seem to sway opinions. As a result, in the  mid-1960-70s, a  surge of outlaw motorcycle gangs emerged across the country and created their own association which they proudly called, One Percenters.  Within  the association, each club could have its own rules, operate independently and given a designated territory.   The outlaw motorcycle clubs; the  Hells Angels, Pagans, Outlaws, and Bandidos emerged as what authorities  refer to the Big Four with hundreds of other one-percenters clubs existing within the subculture. Differences Between Outlaws and One Percenters Defining the differences (and if any exists) between outlaw motorcycle groups and one-percenters depends on where you go for the answer. According to the AMA,  any motorcycle club that does not adhere to AMA rules is considered an outlaw motorcycle club. The term outlaw, in this case, is not  synonymous with criminal or illegal activity. Others, including some outlaw motorcycle clubs, believe that while all one-percent motorcycle clubs are  outlaw  clubs, meaning that they do not follow AMA rules, not all outlaw motorcycle clubs are one-percenters, (meaning that they do not participate in illegal activity. The Department of Justice does not differentiate between outlaw motorcycle gangs (or clubs) and one-percenters. It defines one-percenter  outlaw motorcycle gangs as being highly structured criminal organizations, whose members use their  motorcycle clubs as conduits for criminal enterprises.

Organization and Organizational Change Assignment - 1

Organization and Organizational Change - Assignment Example The solution might require instituting drastic changes in policies or purchase of new machinery to facilitate the work process. However, as common in contemporary organizations, difficulties in the economic condition make financial resources scarce. As such, organizations usually resort to proposed changes which could be unconventional but feasible – if only in the short run. The article discussed the University of Pittsburgh Medical Center (UPMC) Presbyterian Hospital’s strategies for implementing change with regards to the implementation of the Electronic Health Records (EHR) project; especially ways to address resistance to change (Sesack). One is convinced that overcoming resistance to change requires understanding of the need for the change that is to be instituted and communicating the relevance of implementing that change in the work setting. If the need for the change is justified to benefit various stakeholders in the work setting, over and above the current system, inevitably, implementation for change would ensue in a smooth and conflict free manner. It was therefore commendable that the key to overcoming resistance is the ability of leaders to communicate the need for change and allow the personnel to be affected by the change process to see the benefits of the change that would be implemented. The article therefore asserts that there really is nothing to fear with proposed changes. Managers should be able to motivate workers to see that changes would ultimately benefit all concerned in the long run. The article focuses on reasons why implementing change in the work setting fails (Ashkenas). The author evaluated the change theories and ways of implementing change to discern if there is a need to change a crucial facet in the process. As asserted, â€Å"the content of change management is reasonably correct, but the managerial capacity to implement it has been woefully

Risk in the business world Essay Example | Topics and Well Written Essays - 250 words

Risk in the business world - Essay Example There are four basic ways in which a CFO can handle risk; avoid, reduce, assume, or transfer the risk (Silverman, n.d.). A CFO’s attempts should be directed at managing risk in the very order as mentioned here. Personally, a CFO handles risks by collaborating with and influencing the CEO, and also by maintaining independence (Egon Zehnder International, 2008). The challenge for a CFO is to focus on controls, and at the same time, on business partnering. Being able to balance the two conflicting claims enables a CFO to deliver business results. Professionally, a CFO handles risk by trying to assess it in advance and informing the concerned authorities so that it can be managed in time and effectively, if encountered. The best source of risk assessment is historical records and past experiences coupled with expert opinion. In addition, various software like Primavera Risk Analysis can be used to assess and manage risks involved in a

Commentary on Testing the Reality Essay Example for Free

Commentary on Testing the Reality Essay This short but powerfully descriptive poem tells the story of a young man who comes to discover just how fragile the boundary between life and death really is. Written in the form of a dramatic lyric, the poem highlights the moment of revelation and reflection as the man realizes his mother hadnt died; instead she had moved on to another place. The themes of death and abandonment are clearly depicted by the poet through the use of tone, setting, rhythm, symbolism, hyperbole, alliteration and time. Through all these methods, the poet builds a sense of sorrow and feeling of utter reliance the narrator has upon his mother. It emphasizes the mans lifelong journey, from a young child learning to count to a fully grown man mourning the death of his 70-year-old mother. As he grows in body and matures in mind, he fills his head with knowledge and pushes at the boundaries of his world, testing it. The name Testing the Reality arises because the son has to face the reality of life, and the deaths that occur in life. The poem takes place in a church, in a funeral set-up, with flocking birds in the sky. We understand this because of the phrase so crammed church roof and belfry. I can comprehend that it is a funeral because the poet relates the hibernation of the birds to a 70 year old woman. The writer also illustrates a picture of a myriad of birds as he writes There must have been 10,000 there or more. Even though he feels immense loneliness and sadness after the passing on of his mother, he is not yet ready to follow her, and must remain in reality, hence he is the last soul still unhatched. The poem begins in the first person as the poet describes his experiences as a boy. We learn that his mother taught him to count to a ragged 20 but no higher. When he was still a boy, the sheer number of birds perching on the belfry exceeded his counting abilities, cramming church roof and belfry, cross and spire. At this later stage in his life, however, it is not due to his counting skills that he cannot count but due to the sheer immeasurable quantity and their uncontrollable, free nature, unable to be caged or catalogued. Their numbers were so great that their final taking off blacked Beestons sky. These birds feature throughout the poem, creating a sense of activity and movement and dramatic symbolism. Here, the black sky symbolises the unfortunate and sad mood. While the flocking birds represent what the man is looking at and his memories of them as a boy, they also have a metaphorical meaning, symbolizing the life and death of his mother. The crossroad of reality and imagery appears in line six with the following alliteration: picketed piercingly the passing of each day. The power of the repeated P sound reflects the sound of the birds cries. In the poets mind, each bird also represents a single day in the life of his mother. In fact, as the second stanza progresses, the birds only exist to measure the accumulated days in the life of the mans mother. Her attraction towards the birds is completed when they suddenly depart, taking her life with them. The shock of the mothers death is so deep that the first person used throughout the first two stanzas is obliterated and transformed into the third person in the last stanza, the man suddenly being referred to as her son. The third stanza also dramatizes the metaphorical blend of his mother and the birds. Death becomes the wings of night, her life becomes the flocking days. Her departure from the earth is an effusion, a release, of all her physical experiences which are soaring away. So significant was she to her son that her departing life blocked the light. In the final line the son becomes an unhatched egg/soul left behind in the clutch or the nest. Having come to associate the birds with his mother, his memories of her are immediately summoned whenever he sees them. She may be dead but she lives on in his memories of the birds. At first they shrilly hailed the first new light they saw, greeting the new day in what initially seems to be an irritating way because they are portrayed as having loud, high-pitched cries that are not particularly pleasant to the ears. However, after his mother dies, and they leave too, he comes to see them in a different light, after they soared away. His opinion of them has now changed and he sees them as graceful and elegant creatures. This imagery also successfully implies life after death, and the setting of the poem becomes important when looked at in this light. A church is a place of peaceful meditation, praying and holiness, a place where the boundaries between the physical and the spiritual, the barriers between life and death, merge. For these reasons it becomes the nest that hatches souls into the heavens. Even though the birds, and the mans mother with them, fly beyond all sight, hearing, taste, smell, touch they do not fly beyond love or memories, instead leaving a path for the man to follow when it is his turn to be hatched. The lesson the mother taught her son began with counting, but ended with a realization of life after death and the possibility of living, in spirit, for infinity.

Organizational Behavior Synthesis paper Essay

The study of people at work is generally referred to as the study of organizational behavior. This chapter will start by defining the term organizational behavior and briefly reviewing its origins. Organizational behavior is the systematic study of the actions and attitudes that people exhibit within organizations. Each person regularly uses intuition or our â€Å"gut feelings† in trying to explain phenomena. For example, a friend catches a cold and we’re quick to remind him that he â€Å"didn’t take his vitamins†. The field of organizational behavior seeks to replace intuitive explanations such as this example with systematic study. The objective, of course, is to draw more accurate conclusions (Wilson 1994). What does organizational behavior study? Actions (or behaviors) and attitudes. The behaviors that get the bulk of attention in organizational behavior are three, which have proven to be very important determinants of employee performance. They are productivity, absenteeism, and turnover (Wilson 1994). The importance of productivity is obvious. Managers are clearly concerned with the quantity and quality of the work their employees are performing. But absence and turnover are particularly cause for concern because of the adverse affect it may have on an employee ’s productivity. In terms of absence, it’s hard for an employee to be productive if he or she isn’t at work. High rates of employee turnover increase costs and tend to place less experienced people into jobs (Daniels 1994). Organizational behavior is also concerned with employee job satisfaction, which is an attitude. There are three reasons why managers should be concerned with their employees’ job satisfaction. First, there is a link between satisfaction and productivity. Second, satisfaction appears to be negatively related to absenteeism and turnover. Third managers have a humanistic responsibility to provide their employees with jobs that are challenging and rewarding (Daniels 1994). The second part of organizational behavior’s definition that needs to be explained is â€Å"organization†. For our purposes organizational behavior is specifically concerned with work-related  behavior-and that takes place in organizations. An organization is a formal structure o f planned coordination, involving two or more people, in order to  achieve a common goal (Daniels 1994). Organizational behavior is about studying and understanding people and human nature. Do employee ever make efforts on behalf of their employing organization’s interests or fellow employees’ interest when it is not in their direct self-interest to do so? This question exists in any organization must be address. The problem addressed here is a conflict of self-interest. The question here should be very interesting to people in organization. People should try to understand and address counterintuitive behavior in certain situation (Young 1998). For instance, why does moral hazard exists in organization? Organizational behavior success or failure depends on its goal setting, such as group cohesiveness and productivity. In a case study of 2 groups several researchers have suggested that goal acceptance moderates the relationship between group cohesiveness and group productivity. In Study 1, goal acceptance was found to moderate the relationship between group cohesiveness and the quantity of performance of 40 machine crews in a paper mill located in the north eastern United States. In Study 2, the extent to which leaders fostered the acceptance of group goals was found to moderate the relationships between group cohesiveness and quantitative measures of group productivity in 71 insurance agency units located throughout the United States. The companies’ success or failure in this study will be explained in organizational behavior (Jacob 1985) Goals of Organizational Behavior The field of most organizational behavior has an amount of common goals. In order to reach these goals, people need to effectively predict, explain, and manage the behavior that occurs in our organizations. In order to change behavior, one needs to accept that any behavior is rational and logical to the person exhibiting it because his or her goals may differ from others. If an organization is able to predict which reward systems is most effective in motivating the employees, then one can explain the reasons for this effectiveness and describe how managers can enforce effective reward systems. Our everyday lives are about predictions. Predicting the behavior in an organization is usually wondering â€Å"when people will make ethical decisions, create innovative products, or engage in sexual harassment† (Johns 1996).  The behavior in our organizations licenses us the prediction of its future circumstance. Predictions are not always accurate, however. The field of organizational behavior offers a â€Å"Scientific foundation† (Johns 1996). That helps upgrade predictions of these events. But, being able to predict these organization behaviors do not guarantee a hundred percent that he can explain the reason why this particular behavior had developed. A manger needs to be able to get things accomplished, reach all goals, take control, and knows everything that is going on in their company I know that there varieties of management styles to be effective, depending on the situation. There are some cases when a manager acts without investigation, just looking for that quick solution to solve a problem usually results in an unhappy ending. If an organizational behavior â€Å"Can be predicted and explained, it can often be controlled or managed† (Johns 1996). A great manager would be able to predict a certain behavior and have an act on it before it’s too late. Remember, our lives would be more easier if we anticipate when our friends are anger, what our professors expect out of us, and whose lying and telling the truth, â€Å"Regardless of who we are our actions are in response to a variety of motivations† (Wilson 1994). When one understands, one will understand human behavior. Use the predicting. Explaining, and managing principles, and any manger will have the ability to reach your goals through the efforts of others. The four goals of organizational behavior are: 1. To describe systematically how people behave under variety of conditions 2. To understand why people behave as they do 3. To predict future employee behavior 4. to control & develop human activity at work Theory X and Theory Y Theory X and Theory Y are theories of human motivation created and developed by Douglas McGregor at the MIT Sloan School of Management in the 1960s that have been used in human resource management, organizational behavior,organizational communication and organizational development. They describe two contrasting models of workforce motivation. Theory X and Theory Y have to do with the perceptions managers hold on their employees, not the way they generally behave. It is attitude not attributes. There are two kinds of reinforcement, positive and negative. â€Å"Positive reinforcement causes a behavior to increase because a desired, meaningful consequences follows the behavior. Negative reinforcement causes a behavior to increase in order to escape or avoid some unpleasant consequence† (Daniels 1994). Models of Organizational Behavior There are four major models or frameworks that organizations operate out of, Autocratic, Custodial, Supportive, and Collegial (Cunningham, Eberle, 1990; Davis ,1967): o Autocratic — The basis of this model is power with a managerial orientation of authority. The employees in turn are oriented towards obedience and dependence on the boss. The employee need that is met is subsistence. The performance result is minimal. Custodial — The basis of this model is economic resources with a managerial orientation of money. The employees in turn are oriented towards security and benefits and dependence on the organization. The employee need that is met is security. The performance result is passive cooperation. Supportive — The basis of this model is leadership with a managerial orientation of support. The employees in turn are oriented towards job performance and participation. The employee need that is met is status and recognition. The performance result is awakened drives. Collegial — The basis of this model is partnership with a managerial orientation of teamwork. The employees in turn are oriented towards responsible behavior and self-discipline. The employee need that is met is self-actualization. The performance result is moderate enthusiasm. Although there are four separate models, almost no organization operates exclusively in one. There will usually be a predominate one, with one or more areas over-lapping in the other models. The first model, autocratic, has its roots in the industrial revolution. The managers of this type of organization operate mostly out of McGregor’s Theory X. The next three models begin to build on McGregor’s Theory Y. They have each evolved over a period of time and there is no one best model. In addition, the collegial model should not be thought as the last or best model, but the beginning of a new model or paradigm.
