Bohr and the Periodic table :: essays research papers

Bohr's Model   Ã‚  Ã‚  Ã‚  Ã‚  There are three main parts of an atom the electrons, protons and the neutrons. Each part has charge. It is rather positive, negative, or neutral. An electron always has a negative charge. Protons always have negative charges. Then finally the neutron is a neutral charge or a charge of zero. If the charge of the whole atom it zero that means there are an equal number of positive and negative pieces. An electron can be found anywhere around the nucleus, and the protons and neutrons are in the nucleus. You can not pin point were the electrons are but the area that it can be in is called a shell. Periodic Table   Ã‚  Ã‚  Ã‚  Ã‚  On the periodic table the horizontal rows are called periods, and the Vertical columns are called groups. Elements that are in the same row have something in common. Elements in the same period have the same number of atomic shells. Every element in the top row has one shell for its electrons. The second row has two shells for their electrons. Now, the most shells for one element is seven. Less specific groups are called families. Families are grouped by their chemical properties and how the elements react with the outside world. The columns in the periodic table are mostly used to make families. A family of elements can be found in many different ways. An isotope is an atom that is missing or that has an extra neutron. Ionic Bonds   Ã‚  Ã‚  Ã‚  Ã‚  Ions are atoms with an extra electron or a missing electron. But a normal atom would be neutral because it has the same number of electrons as the atomic number. If you are an atom and you are missing one electron, it does not mean that you are another atom, but you are not a complete atom either. You are something new, an ion. The goal of an atom is to be happy. If you have filled shells you are called stable. When you give up the extra electron you are attractive and other atoms want to bond with you. The two main types of bonding are covaent and electrovalent. Ionic bonds are really groups of charged ions held together by electric forces. Covailent Bonds   Ã‚  Ã‚  Ã‚  Ã‚  Covailent compounds happen when the electrons are shared by the atoms.

Critically evaluate whether flexible working arrangements are beneficial for employers and employees?

Flexible work options provides an alternative approache to getting work done through non traditional work hours, job structures ,and locations. The availability of flexible work options grants an opportunity for individuals to mould their careers in order to optimise their work and personal commitments. As for organisation it promises an increase in productivity,boost ‘employer of choice’,reduce fix cost. However flexibility is also reputed as costly for employers and favours unequal treatment in terms of pay and benefits for employees.This essay aims to examine the nature of flexibility and further highlight the different types of flexibility throught the flexible firm model(Atkinson) . In the 1990’s up til present day flexible work practices has become a central point for Uk government policies with Fagan et al (2006) believing globalisation; competition,productivity,active ageing; the long hours culture were particularly the source for the rise of flexible work ing practices.It is important to note that this belief remains the same today, except that advancement in technology is an additional influencing factor. Atkinson’s model of the flexible firm is an arrangement in which mangament offers employees different forms of flexibility practices namely functional,numerial and financial flexibility in order to optimize the use of human resources and quality of work. It is mainly focused on dividing the workforce into core and peripheral groups. The core group entails full time,well paid,secure professional jobs,functional flexible and difficult to replace.Whereas the peripheral group consist of employees who are numerically flexible(Legge) because their skills are abundant in the labour market hence relatively despensible thus low job security,consequently may lead to low productivity due to low morale or they are only needed to complete particular task e. g lawyers. From the employees view,it is better to be part of the core than the p eriphery since the former provides job security,increase career opportunities and better work conditions.Alteration in job design grants the core workers the benefit of soft HR practices implemented to achieve high performance, high commitment and high motivation and thus loyalty to the organisation despite managements persuasion to work across demarcation line as it reduces cost for them. But on the other hand it enhances the ‘its not my job syndrome’in employees(Mcdonals,2010). If employees don’t practice their new skill regularly they loose it. Therefore the cost of training and retraining does not serve the purpose significantly.However in the Uk there is a liking for numerical and temporal flexibility at the expense of functional flexibility(Macdonald,2010). This can be witnessed in an increased use of part timers,short term contract,cleaning agencies. This facilitates the firms ability to adjust the level of labour inputs to meet flunctuations in output(Jen kins,2004). However campos and Cunhas highlights the downside of outsourcing as there is a loss of control over proprietary information and less job security. Nontheless numerical flexibility through part timers helps to reduce costs for employers, for example, workers can be employed when they are needed.It is not necessary to pay for workers who are not productive. This helps attract inward investment. Unlike temporal flexibility it relates to variation in the number of working hours. Flexi time gives employees control over their work schedule thus not only benefiting the employee in terms of achieving a work life balance,job satisfaction but the employer too as it reduces absentism(Lee,1991) therefore higher productivity. Furtheremore teleworking allows employees individual choice in the location of work and covers the possibility to work from home and cutting down job related expenses e. g food,clothes,communiting expense.However Brannen (2005) argues that what appears on the su rface to represent a ceding of control by management to empower employees actually results in a loss of control,because flexible work arrangements unsettles what is a ‘reasonable amount of time’ to spend at work. This is because individuals find it hard to disengage from work. Hence critics of the flexible firm model by Legge. She believed there is a hidden agenda in the flexible firm model,which craftiliy promotes flexibility is good,but the real question is for whom? Futhermore there tends to be a pattern of professional isolation(Macdonald,2010).To conclude one can note that flexibility promises to provide organisations with a competitive edge by cutting down cost for employers,boost employer choice,increase in productivity and assure employees job satisfaction,motivations,work life balance. However,there still appears to be many unresolved issues relating to the flexibility debate. This is highlighted by legge’s critism of mixed empirical support for the flex ible firm model and the advantages of the flexibility is not equally shared. Notedly due to unequal treatment in terms of pay and increased job insecurity for workers.

The Learning Experience of Huck Funn in The Adventures of...

Mark Twain’s novel, The Adventures of Huckleberry Finn, is a story of a boy, Huck Finn, who runs away from home and travels down the Mississippi River with a â€Å"runaway nigger† named Jim. Huck’s father, Pap, is a drunken low life who doesn’t seem to care for his son. He comes from a poor, troubled family and isn’t very educated which is something he seems to embrace. â€Å"Huck Finn runs away not only from an abusive father but also from his good-intentioned guardian, Miss Watson, who tries to civilize Huck, educate him, and make him a Christian† (Sienkewicz). Whether he knows it or not his journey down the river isn’t just an escape, it is a learning experience. Huck learns a few life lessons from dealing with his conscience, to friendship and†¦show more content†¦His whole life has been taught that â€Å"niggers† are property and are not meant to be free but In his heart he knew helping Jim was the right thing to d o, no matter what anybody else says. â€Å"both Huck and Jim are depicted as characters who are capable of learning from their own mistakes, empathizing with others, and acting on the behalf of others† (Evans). As the journey down the river continues they run into two con men. These men pretend to be the Wilks brothers in order to rob this family of all of their possessions. Huck couldn’t see them do this poor family wrong. He spends some time really contemplating telling one of the girls, Mary Jane, the truth about these liars (Twain 175). He knows inside that it is the right thing to do but he doesn’t want to put himself at risk. He plans out every little detail of how he is going to tell her and how he is going to expose these men (Twain 175-178). His actions result from his sympathy for others and his conscience and show major growth as the story continues. True friendship is something you didn’t see very often back then between a little white boy and a grown black man. True friends care and only wish the best for each other. One foggy night Huck and Jim got separated. Huck found the raft again with Jim on it sleeping. He wakes him up and Jim was so happy to see him because he was so worried and thought he was dead (Twain 83). Huck tries to play a trick on Jim and tell him he was only

After finally forming the company group another task was to find out the purpose of the project and understood why this experience could be useful for us (It took almost all day). Furthermore we had to take decisions about how group is going to look like and what tasks we have to do personally: we find out which persons are going to be leaders who are generating the idea and who are going to work with developing and presenting it. * Storming. Secondly we as a very fresh and inexperienced group had to come up with real and innovative business plan. It was the hardest part of all because we didn’t knew each other very good. We had many conflicts about different ideas while finally after many disagreements we find out the best decision of our idea. * Norming. During the working time our relationships grown up significantly. It became much easier to work with each other.

Group analysis based on punctuated equilibrium model: Our group development can be good example of punctuated equilibrium model. First day of our work was very efficient. We formed our group, created first business idea and tried to develop and analyzed it. However after a while working with lost things idea we come up with the decision that we are not able to develop and use it. Then it was period of trying to find new ideas. We had about 10 different solutions however we didn’t stick to none of them until the last day when we had to send one page report. Last minutes work helped us to create and generate good idea and present it to others. Based on knowledge on group development why do you think group work often starts with teambuilding activities like wild-life experiences, bowling, outdoor exercises etc.? In group development is very important feeling and atmosphere through the members. Good relationships and knowing each other are the main keys to productive and efficient work. Teambuilding activities give ability to underst and the way how other people are thinking, how active they are. Furthermore, people always feel much comfortable and relaxed in the known environment. As for my experience in teambuilding trip i can strongly agree that it was the best way to quickly get in the new team. 3. Explain how role conflicts might arise from role perceptions differing from role expectations (try to give a real life example that you have experienced). Personal example: In high school our student council (I was fresh member there) were organizing big event. Leading group announced that everybody can join them and take an active part in developing it. I with other â€Å"freshers† had many interesting thoughts and expectations however how come up in the end we were ably only to participate in cleaning after the party. As a result we felt exploited and misunderstood what caused big conflict between leading and new members. 4. Explain how conformity and status of group members effects team work . Conformity and status are very important part in group development. People are used to behave by first impression. Members who have more experience, are more talented or more self-confident (have higher status than other) are used to be treated as a leaders or be more respected from the first minute. It can have both positive and negative effects through the group. It is important that despite status everybody would have equal right to speak and realize themselves. Furthermore, People often conform from a desire for security within a group—typically a group of a similar age, culture, religion, or educational status. It can prevent people from new ideas and innovation. 5. Explain why group cohesiveness can be both positive and negative for team performance Positive performance| Negative performance| * Individuals are proud to be in the group and see group membership important. As a result they look seriously to the tasks, output and achievements of the group. * Members of cohesive groups deal with conflict openly and constructively. They develop and share values and team loyality. Cohesive groups increase job satisfaction and reduce stress. * When working toward a common goal group members can fill in for each others’ lack of knowledge or shortage of skill. | * Teams members have tendency to adopt similar behaviors that became group norm what can couse lowered productivity or lack of creativity and innovation * Group-think. It happ ens when individual group members lose the ability to think for themselves and rely on the group to make their decisions. * cohesive groups find it difficult to change their values, actions or behaviors, particularly when the change is driven by external forces. Opinions held by the majority or by key group members are regarded as unanimous and alternative views are discouraged| 6. Answer the questions in the â€Å"Ethical Dilemma† page 255 1) If group members end up ‘working around’ shirkers, do you think this information should be communicated to the instructor so that individual’s contribution to the project is judged more fairly? If so, does the group have an ethical responsibility to communicate this to the shirking group member? If not, isn’t the shirking group member unfairly reaping the rewards of a â€Å"free ride’’? Personally I believe that decision have to be made based on situation. I think that first of all group has to try to identify the problem why the member is not working. Maybe he/she has personal problems and can’t concentrate or he/she is not experienced enough that could face the task by himself. Furthermore, is very important to try to speak with the member and say your dissatisfaction directly instead of just throwing him out. If it doesn’t work then group must to communicate with instructor. 2) Do you think confronting the shrinking group member is justified? Does this depend on the skills of shirker (weather he is capable of doing good-quality work)? I believe that everything depends on situation and the task what members have to do. If person is able to do that but just is trying to avoid the work than it is justified. 3) Social loafing has been found to be higher in Western, more individual nations, that other countries. Do you think this means we should tolerate shirking in these countries to a greater degree than if it occurred with someone from more collectivistic nation? I think that social and cultural background has great influence to human character. This is the reason that group members have to be tolerant with each other and try to find the best working method. . Make case incident 2 page 256 1) What are some factors that led to groupthink in the cases described here? What can teams do to attempt to prevent groupthink from occurring? People have tendency not to make quick and efficient decisions. They are trying to avoid conflicts in the team and are not making changes related with a work. They tend to strict to more t raditional and safe decisions. I think that leader have to promote people to represent different ideas and not to be afraid of using different ways. 2) How might differences in status among group members contribute to groupthink? For example, how might lover-status members react to group’s decisions? Are lower-status members more or less likely to be dissenters? Why might higher-status group members be more effective dissenters? Status has very big impact through group members. Individuals with lower-status are tend to keep quietly and not make decisions. They pretend that situation is appropriate for them and company. Higher-status group members are mostly more active and innovative. 3) Microsoft CEO Steve Ballmer says that he encourages dissent. Can such norms guard against the occurrence of groupthink? As a manager, how would you try to cultivate norms that prevent groupthink? I personally believe that encouraging dissent is one of the best ways against the occurrence of groupthink. It stimulates people to think and come up with new ideas or improve the old ones. I would choose the same way. 4) How might group characteristics such as size and cohesiveness affect groupthink? If group is very big and cohesive then it has big risk to be unsuccessful. People are not used to say their opinion or take action. I believe that smaller groups are working more efficient because they get more responsibilities.

Project Management for Operators of Large Assets

Question: Discuss about the Project Management for Operators of Large Assets. Answer: Reflection In the second week, the topic was related to the project management for operators of large assets. It helped me to develop an in-depth knowledge about the topic. Further, it helped me to develop a skill how to assess and select the appropriate project. Through this course, I learnt that cost and benefit analysis is important aspect for selecting the project. Because this analysis helped the project manager to take feasible investment decisions and also provide basis to evaluate the project. Moreover, I have gained the understanding about different types of risks that incurred within the project such as implementation risks, operational risks, financial risks and revenue risks. Before this course, I had no experience about how to manage the risk but, after this course, I have learnt the logical process to manage the risk of the project. In this week, Dr. Deming quotes that Quality management is everyones responsibility (Wong). Through this, I have gained experience and information wha t management could do to address the quality. In addition, Dr. Juran states that without a standard there is no logical basis for making the decision and taking the action (Wong). Hence, I have learnt that quality improvement, quality planning, and quality control are effective for fitness of customers. During this course, from the Crosby quote, I have gained understanding that motivation and role of senior management are beneficial to meet the requirements of the project. From this course, I have gained awareness about different cost of quality such as prevention costs, appraisal costs, internal failure costs and external failure costs. Further, I have enhanced my skills in the quality management and process improvement plan that helped to meet the projects objectives. From the Taguchi Approach, I have learnt that quality can be achieved in the project by minimizing the variation from the objective of the project. From this week portfolio, I have gained my in-depth understanding about the Malcolm Baldrige National Quality Award. This award could be achieved by developing the leadership skills, strategic planning, customer and market information analysis, human resource development, process management and obtain the best quality business result. Along with this, I have gained detailed understanding about the ISO 9000s that helped project manager to develop and implement the quality standard in the project. Moreover, I have learned that project may has an adverse impact on the environment like air, water, human aspects, economic and natural resources hence, environment management is effective to successful implement t he project within the environment. During this course, I have studied the Project Management in Construction book written by Sidney Levy, which helped me to enhance my knowledge about the different skills such as team management, quality control and quality assurance, safety and another topic that necessary to project manager in construction project (Levy, 2011). It also supports me to complete the construction project on time and within the budget. After completing this course, this skill facilitates me to become a good project manager.
