Analysing FIWAREs Platform - Potential Improvements

The digitalization of the world proceeds continuously. As part of this, we are facing a smart digital future where everything is connected and linked while we are transforming big data into knowledge. The FIWARE platform, which is the result of a series of EU funded projects, supports this transformation. Developers, integrators and end users are able to rapidly create new applications, by using components provided by this platform. We have analyzed central building blocks of the FIWARE platform from different aspects and based on experiments and code reviews - identified various areas of improvements. Our analysis also provides some recommendations for the current code base that can help to improve those FIWARE components under investigation

Archbishop John Ireland and the German National Parishes in St. Paul

Archbishop John Ireland dominated the national debate on German language use in parochial schools at the turn of the century. Because of his outspoken desire that Catholics not be viewed as foreigners on American soil, Ireland has been portrayed by critics as a rabid Americanizer who was insensitive to the cultural heritage of non-English speaking Catholic immigrants. A review of Ireland\u27s correspondence and papers, interviews with individuals who knew him, and a search of the historical records of six German-Catholic national parishes in St. Paul reveal that Ireland\u27s public statements on Americanization and his archdiocesan policies regarding the German national parishes were often contradictory. In contrast to his public statements, John Ireland\u27s educational policies were pragmatic, culturally sensitive, and consistent. The archbishop not only tolerated widespread use of German language in parish schoolrooms, he promoted its growth by encouraging the development of national parishes and schools and by providing German-speaking priests and nuns to the congregations

Sustaining momentum: seizing the opportunity for SSR in Sudan

This paper addresses the challenge of security sector reform (SSR) in democratizing Sudan. The former regime developed a sprawling, expensive, corrupt, brutal and ineffective array of military forces, paramilitaries, and security units. The popular uprising that overthrew this regime sought to bring democracy, end the long-running wars in Darfur and the “Two Areas” of Southern Kordofan and Blue Nile, revitalize the economy, end corruption, and reform and downsize the security sector. All these objectives have faced formidable obstacles. Security sector reform has scarcely made it to the political agenda

Sudan’s political marketplace in 2021: public and political finance, the Juba agreement and contests

This paper examines the continuities and changes in Sudan’s political economy and political marketplace in the two years since the popular uprising that overthrew the regime of former president Omar alBashir, and the subsequent formation of a military-civilian transitional government. The government of Sovereignty Council Chairman Abd al-Fattah al-Burhan and Prime Minister Abdalla Hamdok has the stated goals (among others) of transitioning to full civilian government, achieving peace with armed groups, and stabilizing and reforming the economy. Progress has been achieved on all these fronts. Nonetheless, key aspects of Sudan’s political economy remain unchanged, especially underlying hyper-exploitation of labour and natural resources, a prominent role for businesses associated with the leaders of the security sector, and peace agreements incentivized by promises of material rewards provided through governmental office. Transactional politics continue to trump institutional and civic politics, making it harder to reform these aspects of an inequitable and predatory economy

Southeast Asian Adolescents’ Perceptions of Immigrant Parenting Practices

In their countries of origin, immigrant youth are unlikely to question the age-old child-rearing practices of their elders; however, the parenting of adolescents in an adopted country can become a major source of family conflict. The purpose of this study is to investigate how Southeast Asian adolescents growing up in the United States perceive their parents’ practices in six areas of parenting responsibility identified by the National Extension Parent Education Model: caring for self, understanding, guiding, nurturing, motivating, and advocating. Four focus groups were conducted with 37 Southeast Asian (Cambodian, Hmong, Lao, and Vietnamese) adolescent boys and girls between the ages of 14 to 19 years to ascertain how they perceived parenting behaviors. An analytic induction procedure was used to analyze transcripts from in-depth focus group discussions. Results indicate wide divergence between the idealized practices of the model, the parents’ actual practices, and adolescents’ perceptions of parenting practices. The study has important implications for the growing number of immigrant families from diverse cultures who are parenting adolescents in unfamiliar cultural contexts and for the educators, human service providers, and others who work with them

Sound power and timbre as cues for the dynamic strength of orchestral instruments

In a series of measurements, the sound power of 40 musical instruments, including all standard modern orchestral instruments, as well as some of their historic precursors from the classical and the baroque epoch, was determined using the enveloping surface method with a 32-channel spherical microphone array according to ISO 3745. Single notes were recorded at the extremes of the dynamic range (pp and ff) over the entire pitch range. In a subsequent audio content analysis, audio features were determined for all 3482 single notes using the timbre toolbox. In order to analyze the relative contributions of timbre- and amplitude-related properties to the expression of musical dynamics in different instruments, Bayesian linear discriminant analysis and generalized linear mixed modelling were employed to determine those audio features discriminating best between extremes of dynamics both within and across instruments. The results from these measurements and statistical analyses thus deliver a comprehensive picture of the acoustical manifestation of “musical dynamics” with respect to sound power and timbre for all standard orchestral instruments.DFG, 174776315, FOR 1557: Simulation and Evaluation of Acoustical Environments (SEACEN

On the representation of cells in bone marrow pathology by a scalar field: propagation through serial sections, co-localization and spatial interaction analysis

Background: Immunohistochemical analysis of cellular interactions in the bone marrow in situ is demanding, due to its heterogeneous cellular composition, the poor delineation and overlap of functional compartments and highly complex immunophenotypes of several cell populations (e.g. regulatory T-cells) that require immunohistochemical marker sets for unambiguous characterization. To overcome these difficulties, we herein present an approach to describe objects (e.g. cells, bone trabeculae) by a scalar field that can be propagated through registered images of serial histological sections. Methods: The transformation of objects within images (e.g. cells) to a scalar field was performed by convolution of the object’s centroids with differently formed radial basis function (e.g. for direct or indirect spatial interaction). On the basis of such a scalar field, a summation field described distributed objects within an image. Results: After image registration i) colocalization analysis could be performed on basis scalar field, which is propagated through registered images, and - due to the shape of the field – were barely prone to matching errors and morphological changes by different cutting levels; ii) furthermore, depending on the field shape the colocalization measurements could also quantify spatial interaction (e.g. direct or paracrine cellular contact); ii) the field-overlap, which represents the spatial distance, of different objects (e.g. two cells) could be calculated by the histogram intersection. Conclusions: The description of objects (e.g. cells, cell clusters, bone trabeculae etc.) as a field offers several possibilities: First, co-localization of different markers (e.g. by immunohistochemical staining) in serial sections can be performed in an automatic, objective and quantifiable way. In contrast to multicolour staining (e.g. 10-colour immunofluorescence) the financial and technical requirements are fairly minor. Second, the approach allows searching for different types of spatial interactions (e.g. direct and indirect cellular interaction) between objects by taking field shape into account (e.g. thin vs. broad). Third, by describing spatially distributed groups of objects as summation field, it gives cluster definition that relies rather on the bare object distance than on the modelled spatial cellular interaction
