    This Bachelor thesis provides an analysis of Runge-Kutta methods using Butcher tableaus. Runge-Kutta method are numerical methods used for approximating initial value problems. A Runge-Kutta method can be classified as either an explicit or an implicit method. A special kind of implicit methods are diagonally implicit methods. The type of method can be recognised by the Butcher tableau. Using the entries of the Butcher tableau, one can compute the amplification factor of a Runge-Kutta method. The amplification factor can then be used to compute the order of the local truncation error and the stability region. Examples of these computations are given for seven methods. Furthermore, this thesis provides an algorithm to perform time steps for each of the three types of Runge-Kutta methods. Finally, in order to analyse the global truncation error of the seven methods, the algorithm to perform time steps is used with different step sizes.Applied Mathematic

    Exclusion, Inclusion and Enclosure: Historical Commons and Modern Intellectual Property

    No full text
    The global debate over intellectual property rights (IPR) relating to genomics, soft- ware, and scientific information has divided developed and developing countries in international fora. Fundamental issues undergird these debates: who is to be excluded from various kinds of information, and who is to be included in the benefits of these ideas? An insight into these issues may be gained from the history and theory of property rights in land, especially the enclosure of lands held in common. After considering successful examples of common property, the paper con- siders the modern debate over common intellectual property

    A restricted Runge-Kutta method

    Consider the differential system dy[subscript r]/dx = f[subscript r](x, y���, y���, ..., y[subscript m]), y[subscript r](x���) = r[subscript r0] (r = 1, 2, ..., m). The Runge-Kutte method applies to all functions f[subscript r](x, y���, y���, ..., y[subscript m]), of suitable differentiability. By restricting the class of functions to g[subscript r](x) + r[subscript r1]y��� + ... + c[subscript rm]y[subscript m] where g[subscript r](x) are arbitrary functions of x and c[subscript rj] arbitrary constants, the nth order of this restricted Runge-Kutte method for the explicit case can be defined as [y bar][subscript r1] = y[subscript r0] + [sigma q i=1] R[subscript i]k[subscript ri]. ..

    Community College Goal Alignment: Executive Goal Setting within Performance Management

    No full text
    As state and local funding for public community colleges has decreased and students bear a greater proportion of educational costs, a community college education is being considered more frequently as a “private good” in contrast to a “public good” (Katsinas, 2005; Phelan, 2005). Community college leaders are realizing the limit of what students can and should bear for tuition and fees, especially in light of equity and access issues (Dowd, 2007). To manage tuition rates and sustain open access, community colleges must rely on employees to achieve organizational objectives with fewer resources. Therefore, quality employee performance directed to the accomplishment of organizational goals is essential to organizational performance. Very little is known about how goals are aligned through strategic planning and performance appraisal processes in community colleges, as evidenced by the few scholarly articles about community colleges available in the literature. This study explored how public community college leaders and human resource departments can assist executives with the alignment of organizational goals and individual goals through a performance appraisal review process that incorporates professional development. Goal theory was the primary motivational COMMUNITY COLLEGE GOAL ALIGNMENT theory utilized in this study. Psychological contract theory provided a relevant theoretical basis for understanding the employer-employee relationship in this study. A mixed-methods research methodology was applied. An exploratory and descriptive multiple-case study of four community colleges selected through purposeful sampling provided in-depth information about how community colleges align organizational and individual goals at the executive level and how this alignment impacted organizational performance. Analysis of the findings indicated that best practice community colleges achieved performance improvement through the following managerial actions: 1) senior leadership endorsed performance appraisal review processes; 2) performance appraisal reviews referenced college goal-setting processes; 3) managerial controls were implemented to facilitate performance appraisal review completion; 4) regular feedback opportunities were ensured; 5) executives were encouraged to plan and invest in professional development; and 6) community colleges or their respective system offices continually evaluated their performance management systems.COMMUNITY COLLEGE GOAL ALIGNMENT ABSTRACT Title of Dissertation Community College Goal Alignment: Executive Goal Setting within Performance Management Carol E.

CHAPTER 1: INTRODUCTION Statement of the Problem Public community colleges have been asked to provide additional educational opportunities and services to their communities with fewer resources. State and local budgets, which are sources of a high percentage of community college funding, have been significantly reduced (Katsinas, 2005; Phelan, 2005). Because of one of the most extensive recessions within the last 80 years, community college enrollment has surged. College leaders realize that there is a limit to the financial burdens students can and should bear, especially in light of equity and access issues (Dowd, 2007). Legislators, taxpayers, families, and students have demanded increased accountability for student success from community colleges (The Secretary’s Commission on the Future of Higher Education, 2006). In addition, community colleges have been urged to focus their efforts upon the national degree completion initiative (McPhail, 2011). Shults (2008) contends that community colleges must undergo major restructuring to achieve success and that one area to manage is maximizing human capital to gain a competitive advantage. The typical community college workforce is rapidly changing as increased numbers of long-time employees retire. For example, retirement of senior administrators and faculty is underway and may accelerate as retirement incentives are offered to reduce the number of employees during the current budget crises (Flannigan, Jones, & Moore, 2004). Those who remain employed face increased workloads. In one study, 84% of 114 chief academic officers indicated that administrator training/career development and technological competence were important issues to manage (Cejda & Leist, 2006). Community college leadership has responded to these challenges by altering organizational structures and practices. Efforts to improve performance have been in place for COMMUNITY COLLEGE GOAL ALIGNMENT 2 over 15 years, as exemplified by six community college leaders who described their efforts to focus the college mission on student learning (O’Banion, 1997). Following these efforts, evidenc

    Are Fe and P availabilities involved in determining the occurrence and distribution of Calluna vulgaris (L.) Hull in semi-arid grasslands on calcareous soils?

    Calluna vulgaris (L.) Hull is primarily found on acid soils and is generally classified as a calcifuge species. Therefore, its occasional growth in semi-arid grassland on shallow calcareous soils gave rise to the question as to whether special soil conditions, deviating from the typical conditions in calcareous soils, enable this unusual occurrence. In an attempt to answer this question, we analysed selected soil factors, comparing plots where C. vulgaris was growing besides calcicole species (=CF plots) with neighbouring plots where only calcicole species were present (=CC plots). Main emphasis was placed on Fe and P availability because results from growth experiments indicate that the availability of either Fe or P to calcifuges causes calcifuge species to fail on calcareous soils. The results of our investigations do not support the hypothesis that the occurrence of C. vulgaris in semi-arid calcareous grasslands depends on higher Fe and/or P availability. Rather, its growth on carbonate-buffered soils shows that this species is not really calcifuge. Since the CF plots differ from the CC plots either by a lower inclination or by a more northerly exposition, we assume that the primary establishment and this species' distribution pattern in the investigated semi-arid grassland are not dependent on soil chemical factors, but are governed by topography and its consequences for soil humidity and drought stress.Deutsche Forschungsgemeinschaft [Ru 136/10-1, 10-2

    Mixed collocation methods for y” = f(x , y)

    The second-order initial value problem y" = f(x,y), y(x(_0)) = y(_0), y'(x(_0)) = z(_0) which does not contain the first derivative explicitly and where the solution is oscillatory has been of great interest for many years. Our aim is to construct numerical methods which are tuned to act efficiently on strongly oscillating functions. The frequencies involved determine the oscillatory character of the function and as the frequencies approach zero, the classical methods are obtained. The exponential- fitting tool has become increasingly popular as it is specially tailored for oscillating functions. Many classes of methods have been used with exponential-fitting and this will be discussed in more detail in the thesis. Collocation methods are considered for which the basis functions are combinations of polynomial and trigonometric terms. The resulting methods can be regarded as Runge-Kutta-Nyström methods with steplength dependent coefficients. We show how order conditions may be obtained, investigate the stability and other properties of particular methods and present some numerical results
