    Effective Systems Engineering Training

    The need for systems engineering training is steadily increasing, as both the defense and commercial markets take on more complex "systems of systems" work. A variety of universities and commercial training vendors have assembled courses of various lengths, format, and content to meet this need. This presentation looks at the requirements for systems engineering training, and discusses techniques for increasing its effectiveness. Several format and content options for meeting these requirements are compared and contrasted, and an experience-based curriculum is shown

    Muslims, Catholics, and the secular state

    Full text link
    Any attempt to explore the relationship between representations of Muslims and public advocacy in modern Western societies must at some point situate both processes in relation to the broader crises of liberal citizenship currently afflicting Western democracies. Calls heard in the 1990s for multicultural citizenship and pluralist “recognition” have long since given way to demands for the exclusion of new immigrants and the coercive assimilation of those – especially Muslims -- long since arrived. This essay examines French Catholic and Muslim perspectives on secularism and citizenship in contemporary France. It highlights disagreements among progressive secularists as well as mainline Catholics and Muslims over how to engage the secular state as well as one’s fellow citizens. It explores the ways in which Catholic advocacy for and with Muslim citizens has been challenged by conservative trends in French Catholicism, as well as the perceived rise of Salafism and, most important, growing support for far-right and Islamophobic movements. The example shows that real-and-existing public spheres look less like the genteelly deliberative public spaces Jurgen Habermas described a generation ago. They are landscapes reshaped by movements, social media, and political entrepreneurs making use of reductionist arguments and media caricature (“fake news”) as much as or even more than deliberative reasoning. These realities present serious challenges to those who hope to use education and dialogue in public advocacy with and for Muslim citizens.Accepted manuscrip

    Emergent Landscape: Urban Shadow Space, Illuminated

    Get PDF
    This study defines a new approach to the transformation of unmaintained land within cities, or urban shadow space. Although urban shadow space can offer a place of free expression for the community and spontaneous vegetative growth within a city, it is often dismissed as blighted land by public authority. This study maximizes existing opportunities of these spaces, illuminating a realm of the city that is currently dark to the public eye. A proposed set of guidelines is utilized in the creation of three alternative designs that illustrate the emergent landscape, a sensitively designed, evolving landscape that encourages user interaction with the site. These guidelines and the results of their application are intended to assist design professionals who wish to move beyond the typical “clean and green” strategy currently employed by many municipalities to embrace a site’s existing characteristics

    Status of linear boundary-layer stability and the e to the nth method, with emphasis on swept-wing applications

    Get PDF
    The-state-of-the-art for the application of linear stability theory and the e to the nth power method for transition prediction and laminar flow control design are summarized, with analyses of previously published low disturbance, swept wing data presented. For any set of transition data with similar stream distrubance levels and spectra, the e to the nth power method for estimating the beginning of transition works reasonably well; however, the value of n can vary significantly, depending upon variations in disturbance field or receptivity. Where disturbance levels are high, the values of n are appreciably below the usual average value of 9 to 10 obtained for relatively low disturbance levels. It is recommended that the design of laminar flow control systems be based on conservative estimates of n and that, in considering the values of n obtained from different analytical approaches or investigations, the designer explore the various assumptions which entered into the analyses

    Combined riblet and lebu drag reduction system

    Get PDF
    The invention is a system of flow control devices which result in reduced skin friction on aerodynamic and hydrodynamic surfaces. The devices cause a breakup of large-scale disturbances in the boundary layer of the flow field. The riblet device acts to reduce disturbances near the boundary layer wall by the use of longitudinal striations forming V-shaped grooves. These grooves are dimensional on the order of the wall vortices and turbulent burst dimensions. The large eddy breakup device is a small strip or airfoil which is suspended in the upper region of the boundary layer. Various physical mechanisms cause a disruption of the large-scale vortices. The combination of the devices of this invention result in a substantial reduction in skin friction drag

    The politics of Indonesia's new criminal code

    Get PDF
    The new Criminal Code released in Indonesia in early 2023 is intended to free the country's legal system of lingering colonial heritages. However, the Code has also stirred controversy because of its criminalization of certain sexual behaviors not previously subject to legal penalty. In this report I review the major features of the new Criminal Code, and explore their implications for human rights and sexual freedoms.Published versio

    Using Planned Reading Circles to Increase Pre-service Special Education Teachers\u27 Content Knowledge

    Get PDF
    This presentation will describe the implementation of an appropriate and effective teaching method to help pre-service teacher candidates learn about major course topics. As a method of teaching course content the presenter implements reading circles and the use of the wiki to teach course content in a college course for pre-service special education teacher candidates. The reading circles offer a direct way to encourage reading of course content and, in turn, lead to a better understanding of course content. The wiki allows the students to construct, discuss, revise, and fine-tune their understandings and interpretations of assigned readings. Both the reading circle and the wiki emphasize collaboration through an ongoing process and, as such, complement each other in very powerful ways. This approach to teaching course content allows future teachers to not only increase their knowledge of course content but to develop an understanding of how the implementation of reading circles along with the wiki might be useful to them in their own classrooms. This presentation will offer participants information on how to implement this approach to teaching content in almost any college course. This is a research project in progres
