a) Compare interstitial and vacancy atomic mechanisms for diffusion. (b) Cite two reasons why interstitial diffusion is normally more rapid than vacancy diffusion. Solution (a) With vacancy diffusion, atomic motion is from one lattice site to an adjacent vacancy. Self-diffusion and the diffusion of substitutional impurities proceed via this mechanism. On the other hand, atomic motion is from interstitial site to adjacent interstitial site for the interstitial diffusion mechanism. (b) Interstitial diffusion is normally more rapid than vacancy diffusion because: (1) interstitial atoms, being smaller, are more mobile; and (2) the probability of an empty adjacent interstitial site is greater than for a vacancy adjacent to a host (or substitutional impurity) atom. .

B. define decentralization and provide an example of an organization that has successfully implemented this policy. C. How should managers deal with income tax issues when choosing a transfer-pricing method that involves multinational considerations? D. Solution A. Yes, I completely agree with this Statement. Every Organization adopt both the Philosophies. Organization must establish whether its decision-making policies are centralized or decentralized. Highly centralized companies tend to have more bureaucratic traits, while highly decentralized companies tend to appear more out of control. Both extremes appear engulfed with inefficiencies and waste. High performance work systems seem to have more decentralized decision-making features, yet their culture, formed around their philosophy and values, is highly centralized. Creating a centralized philosophy and value system allows employees to become more empowered to make their own decisions, leading to decentralization. B. Decentralization is characterized by relatively few layers of management, with few centralized policies and procedures. Each group, whether a division, location, or team, creates its own practices based mostly on the organization .

Do they have a choice in the matter? Explain how. B. from monitoring employee email communications? Discuss whether or not you think the company has a right to monitor email and personal use of the Internet and explain why. C. Discuss the collection of evidence for audits of an AIS. How is it different from evidence collection for a company that doesn\'t utilize AIS? Solution 1.\"Information is Power\" and this wisdom is being increasingly used in business .Companies collect demographic, psychographic and behavioural information of the customer through direct and indirect methods. While a survey could be a direct method , there are many data analytic tools that are available to collect data on psychographics and behaviour from the purcahse history of the buyers , and all thses are indirect methods. One of the example is of Facebook and Google monitoring the site visits of users and profileing them for more focused advertisements. 2.In this digital world where everyone is connected virtually , it is impossible to survive without mails , whether it is official or personal. Organizations should not snoop into personal mails of employees unless otherwise those mails are affecting official work.It is wrong to tresspass into private matters. 3.Evidence can be collected in traditional way and also digitally. Collection of digital information is more easy and relevant and the wrong doers can be detected online promptly. .

detail the significant ways that an awareness of emotional intelligence can improve a leaderâ€™s effectiveness. Select a situation in which you demonstrated emotional intelligence that improved your effectiveness as a leader, either in your professional or personal life. Solution Emotional intelligence (EI) is the ability to understand and manage your own emotions, and those of the people around you. People with a high degree of emotional intelligence know what they\'re feeling, what their emotions mean, and how these emotions can affect other people. There are five main elements of emotional intelligence, namely: Situation in professional life. When I was working as a manager of business, there was a good performer in the team who was vey intelligent and understood work very well, but was a laszy person on the other hand. There were several others who were hard working, but not as intellegent as him. Hence Motivation amd empathy were two skills that helped me make this person understand his true potential which made him excel in his career. Hence I was positvely able to transform this perfor through emotional intelligence .

Despite theoretical assertions by M-M and others, many investors do care about dividends quite a bit. The chart below lists some factors are likely to make an investor prefer to receive more or fewer dividends. Indicate whether the factors are likely to make an investor prefer to receive more or fewer dividends. Factor Investors will likely prefer More dividends Fewer dividends Dividends are taxed in the year they are received, while capital gains are taxed when the stock is sold. When investors receive dividends today, they may choose to reinvest or consume goods. An investor is on a fixed income and depends upon returns from investment. If an investor dies, his heirs are not liable for taxes on the capital gains generated during the investor\'s life. They are only liable for the capital gains earned since the investor\'s death. The value of a dividend received today is known, but the value of a capital gain received in the future is uncertain.

Develop a research paper providing an overview of what construction design communications are, which project team members (disciplines) use them, and how they are used (what information they provide). Discuss the key aspects of design and the design process (phases) as a whole. Compare and contrast the different types of drawings and discuss their importance to an effective and efficient construction process. Support the paper with research from the online course material, text, and outside sources if necessary. Solution Effectiveness of team communication for the design of buildings is becoming increasingly important due to the growing technical and organizational complexity of construction projects. The development and use of information communication technologies (ICTs) has been seen as one way of improving the performance of design and construction teams . ICTs have also become synonymous with the better integration of project participants (e.g. Warning and Wainwright, 2000) and also a means of improving collaborative working .

Describe, in detail, what would happen if you fell into a black hole, from both your perspective, and the perspective of someone who is watching you fall in. You should include specific effects, including effects on space, time, and what you would see. Solution It\'s safe to say you wouldn\'t survive the trip, so stay on this side of the Event Horizon if you ever want to be seen again. Black Holes are massive objects occupying a tiny volume in space. When a super-massive star (many times larger than the Sun) stops sustaining enough nuclear fusion at its core to support its size, its mass may collapse into itself and form a Black Hole, sucking in everything around it. Our Milky Way galaxy spirals around a super-massive Black Hole at its center. Since nothing can escape from the incredible gravitational pull of a Black Hole (even light itself), scientists can only speculate on what would happen to a person falling into a Black Hole. However, it does seem evident that the crushing gravity would not be kind to your body. Soon after passing the Event Horizon, the point of no return, your body\'s atomic structure would be ripped apart. The parts of your body closer to the singularity experience a stronger gravitational pull than the parts of your body further away from the singularity. This \"tidal gravity\" creates a differential gravitational pull on your body that literally stretches you out as you fall in. Alas, the rack of space-time is unforgiving to even the most pliant mind, and ultimately it\'s impossible to keep yourself together. .

Describe what is meant by the dipole nature of a water molecule. How is this related to adsorbed water? Why does the presence of water in soil typically have a much greater effect on clays than in granular soils (i.e. sand)? Solution Water consist of hydrogen and oxygen atoms. The two hydrogen atoms are not symmetrically arranged around the oxygen atoms which leads to diploe nature of water. Dipole water can be electrically attracted towards the surface of the clay particles. there are 3 mechanism by which water is attracted to surface of clay particles resulting in adsorbed water. 1) Attraction between negatively charged faces of clay particles and positive end of dipoles. 2) Attraction between cations in double layer and negatively charged ends of dipoles. 3) sharing of hydrogen atoms in water molecule by hydrogen bonding between oxygen atoms in clay particles and oxygen atoms in water molecule. Since the water adsorbs on surface of clay particles, it affects various properties of clay like plasticity. The mechanisms by which water is attracted to clay particles does not takes place in granular soil. Hence water has greater effect in clayey soils than granular soils. .
