...In this method the sender uses a key with some enhanced rules and regulations to encrypt the simple text (plain text) into cipher text that need to send to receiver. The receiver also applies the same enhanced rules to decrypt the cipher text in-order to get the Original content of the message. Actually a single key employs for both process, so it is called as symmetric key cryptography. Figure 1.1 Specific Key Cryptography Secret key cryptography contains continuous ciphers (stream ciphers) or complex ciphers (block ciphers). Continuous ciphers (stream ciphers) are applied on a single bit (computer word or byte) at a time, so that the key constantly in changing form due to some form of observation (feedback) mechanism employed. The block cipher also employed by same nature but it applies on 1 block of information (data) at the same time by using the similar key on each of the block. In stream cipher plain text will be encrypted to different cipher text but in block cipher plain text block is always encrypted to same cipher data block. 1.3.1.1 Classification of Private Key Cryptography There are two classes of private-key cryptography scheme which are commonly distinguished as block ciphers and stream...

Change can be caused by conflict or in itself can create conflict. In leading team development, managers must understand their employees and their team in order to lead them forward through daily conflict resolution. By using non-defensive mediation techniques, a manager can help each team member create a voice, invest them in the process of change, and lead their team to success. Conflict transformation has been used to resolve international issues since the 1970’s. Strategic and powerful, these tactics can poise a manager for corporate success. Systemic conflict analysis and conflict monitoring, with key shareholders, creativity in the imagination of sustainable solutions, strategic planning of systemic interventions, and mobilization of agents of peaceful change are the core elements of conflict transformation. 1 Engaging key shareholders requires understanding the people and team dynamics within the conflict. This gives managers a place to begin. Analyzing and monitoring conflict transformation using non-defensive communication allows the manager to creatively develop and implement solutions within a supportive team environment. Consider the following case study.2 An annual staff meeting included...

...In this paper we are going to follow King Lear through his journey from being an arrogant King to finding his humanity and point to key moments that help him to gain a clear vision or open his mind’s eye as opposed to his short sightedness. This is a very important theme and throughout history alchemists, poets and writers have been focused on it. For example Rumi in his poetry mentions that if we open the mind’s eye then we see all the secrets of the world in front of us. Before diving into the details of words and imagery let’s have a look at key synopsis and events in the play related to our theme: * 1.1.130 Lear uses flattery test to divide his kingdom (shortsightedness) * 1.1.161 Overtaken by anger Lear says “out of my sight” to Cordelia his favorite daughter (anger) * 1.1.16 Lear banishes loyal Kent for his honesty (anger) * 1.4.9 Lear does not recognize Kent in disguise and employs him again (shortsightedness) * 1.4.200 Lear asks “Where are his eyes?” (confusion) * 1.4.204 “Lear’s shadow” is fool’s answer to Lear question about how he is (fool wise words) * 1.5.20-21 “To keep one’s eyes of either side’s nose, that what a man cannot smell out he may spy into” (Fool wise word) * 1.5.36-37 “If thou wert my fool, nuncle, I’d have thee beaten for being old before your time.” (Fool) * 3.2.1-13 “Blow winds and crack your cheeks!

There are two variables in the study, the mental set and behavior. Mental set is defined as the tendency to solve certain problems in a fixed way based on previous solutions to similar problems. Behavior is the response of an individual or group to an action, environment, person, or stimulus. The construct of a mental set in classroom management is quite similar to the construct of “mindfulness” in psychology. Langer explains that mindfulness involves a heightened sense of situational awareness and a conscious control over one's thoughts and behavior relative to that situation. http://www.ascd.org/publications/books/103027/chapters/Mental-Set.aspx Introduction Mental sets are subconscious tendencies to approach a problem in a particular way. It is a framework for thinking about a problem and can be shaped by habit, past experiences or by desire. Mental sets can make it easy to solve a class of problem, but attachment to the wrong mental set...

...than another bargain with a more certain, but possibly lower, expected payoff. For example, a risk-averse investor might choose to put his or her money into a bank account with a low but guaranteed interest rate, rather than into a stock that may have high expected returns, but also involves a chance of losing value. ------------------------------------------------- Utility of money[edit source | editbeta] In expected utility theory, an agent has a utility function u(x) where x represents the value that he might receive in money or goods (in the above example x could be 0 or 100). Time does not come into this calculation, so inflation does not appear. (The utility function u(x) is defined only up to positive linear affine transformation - in other words a constant offset could be added to the value of u(x) for all x, and/or u(x) could be multiplied by a positive constant factor, without affecting the conclusions.) An agent possesses risk aversion if and only if the utility function is concave. For instance u(0) could be 0, u(100) might be 10, u(40) might be 5, and for comparison u(50) might be 6. The expected utility of the above bet (with a 50% chance of receiving 100 and a 50% chance of receiving 0) is, , and if the person has the utility function with u(0)=0, u(40)=5, and u(100)=10 then the expected utility of the bet equals 5, which is the same as the known utility of the amount 40. Hence the certainty equivalent is 40. The risk premium is ($50 minus $40)=$10, or in...

Marlene Fiol University of Colorado - Denver Drew Harris Fairleigh Dickinson University Robert House University of Pennsylvania Second revision February 1999 Please address all correspondence to: C. Marlene Fiol University of Colorado at Denver College of Business CB 165 PO Box 173364 Denver CO 80217-3364 303-556-5812 mfiol@castle.cudenver.edu CHARISMATIC LEADERSHIP: STRATEGIES FOR EFFECTING SOCIAL CHANGE ABSTRACT Due to their unique relationship with followers, charismatic leaders can be powerful agents of social change. Current theories of charismatic leadership have emphasized primarily the personality and behavior of leaders and their effects on followers, organizations, and society. This emphasis fails to uncover why and how the charismatic leader-follower interaction can generate social change. Our study draws on theories of social meaning to develop a process model of charismatic leadership. Empirical exploration of our model suggests that charismatic leaders employ a set of consistent communication strategies for effecting social change. INTRODUCTION We have substantial evidence that charismatic leaders behave differently than non-charismatic leaders. Further, we know that charismatic leaders can generate radical social changes, and that the performance of charismatic leaders and their followers tends to exceed that...

...regression, and residual assessment. SUMMARY: Researchers are often faced with the need to describe quantitatively the relationships between outcomes andpre d i c t o r s , with the objective of ex p l a i n i n g trends, testing hypotheses, or developing models for forecasting. Regression models are able to incorporate complex mathematical functions and operands (the variables that are manipulated) to best describe the associations between sets of variables. Unlike many other statistical techniques, regression allows for the inclusion of variables that may control for confounding phenomena or risk factors. For robust analyses to be conducted, however, the assumptions of regression must be understood and researchers must be aware of diagnostic tests and the appropriate procedures that may be used to correct for violations in model assumptions. CONCLUSION: Despite the complexities and intricacies that can exist in re gre s s i o n , this statistical technique may be applied to a wide range of studies in managed care settings. Given the increased availability of data in administrative databases, the application of these procedures to pharmacoeconomics and outc o m e s assessments may result in more varied and useful scientific investigationsand provide a more solid foundation for health care decision making.

Change takes time and cost money. The objective of the paper is to discuss the failure of ineffective transformation and clarifying the process for change to save guide leaders to successfully implement effective transformation. Keywords: Five Ps, Resistance, Vision, Strategy, tactics and People INTRODUCTION Today change is universal. Change is essential in both public and private sector organization to be competitive in today’s turbulent environment. Often leaders failed to successfully transform their organizations in achieving their business goals. In fact, most of the leaders fails to understand the type of resistance involve, therefore ending up wasting a lot time in inappropriate measure of trying to solve the problem. Further more we often miss some of the significant part of the transformation process in which our change efforts turns to be not that effective as we expect to. In order to successfully bring transformation we need to sail out to all the three islands of change 1. RESISTANCE TO CHANGE Change is dealing more with the behaviors. As often when trying to get people out of their comfort zones it’s...
