A Review of existing GDPR Solutions for Citizens and SMEs

The GDPR grants data subjects certain rights, like the right to access their data from companies, but in practice multiple problems exist with exercising these rights such as unknown data holders or interpreting the received data. Small and medium enterprises on the other hand need to facilitate the obligations given by the GDPR, but often lack proper systems, staff and other resources to do so effectively. For the GDPR to be effective in practice, these problems need to be addressed. With the work at hand we provide an overview of existing software solutions for these problems (from an internet research), discuss to which degree they solve the various problems and what issues remain.Comment: 46 page

Solvent Annealing of Striped Ellipsoidal Block Copolymer Particles: Reversible Control over Lamellae Asymmetry, Aspect Ratio, and Particle Surface

Solvent annealing is a versatile tool to adjust the shape and morphology of block copolymer (BCP) particles. During this process, polar solvents are often used for block-selective swelling. However, such water-miscible solvents can induce (partial) solubilization of one block in the surrounding aqueous medium, thus, causing complex structural variations and even particle disassembly. To reduce the complexity in morphology control, we focused on toluene as a nonpolar polystyrene-selective solvent for the annealing of striped polystyrene-b-poly(2-vinylpyridine) (PS-b-P2VP) ellipsoids. The selective stretching of PS chains produces unique asymmetric lamellae structures, which translate to an increase in the particle aspect ratio after toluene evaporation. Complete reversibility is achieved by changing to chloroform as a nonselective solvent. Moreover, surfactants can be used to tune block-selective wetting of the particle surface during the annealing; for example, a PS shell can protect the internal lamellae structure from disassembly. Overall, this versatile postassembly process enables the tailoring of the structural features of striped colloidal ellipsoids by only using commercial BCPs and solvents.Fil: Navarro, Lucila.

Hierarchical and dynamic threshold Paillier cryptosystem without trusted dealer

We propose the first hierarchical and dynamic threshold Paillier cryptosystem without trusted dealer and prove its security in the malicious adversary model. The new cryptosystem is fully distributed, i. e., public and private key generation is performed without a trusted dealer. The private key is shared with a hierarchical and dynamic secret sharing scheme over the integers. In such a scheme not only the amount of shareholders, but also their levels in the hierarchy decide whether or not they can reconstruct the secret and new shareholders can be added or removed without reconstruction of the secret

Towards Secure Evaluation of Online Functionalities (Corrected and Extended Version)

To date, ideal functionalities securely realized with secure multi-party computation (SMPC) mainly considers functions of the private inputs of a fixed number of a priori known parties. In this paper, we generalize these definitions such that protocols implementing online algorithms in a distributed fashion can be proven to be privacy-preserving. Online algorithms compute online functionalities that allow parties to arrive and leave over time, to provide multiple inputs and to obtain multiple outputs. In particular, the set of parties participating changes over time, i.e., at different points in time different sets of parties evaluate a function over their private inputs. To this end, we propose the notion of an online trusted third party that allows to prove the security of SMPC protocols implementing online functionalities or online algorithms, respectively. We show that any online functionality can be implemented perfectly secure in the presence of a semi-honest adversary, if strictly less than 1/2 of the parties participating are corrupted. We show that the same result holds in the presence of a malicious adversary if it corrupts strictly less than 1/3 of the parties and always allows the corrupted parties to arrive and provide input. Note, this is the corrected and extended version of the work presented in [24]

Radioprotective effect of lidocaine on neurotransmitter agonist-induced secretion in irradiated salivary glands.

Previously we verified the radioprotective effect of lidocaine on the function and ultrastructure of salivary glands in rabbits. However, the underlying mechanism of lidocaine's radioprotective effect is unknown. We hypothesized that lidocaine, as a membrane stabilization agent, has a protective effect on intracellular neuroreceptor-mediated signaling and hence can help preserve the secretory function of salivary glands during radiotherapy. Rabbits were irradiated with or without pretreatment with lidocaine before receiving fractionated radiation to a total dose of 35 Gy. Sialoscintigraphy and saliva total protein assay were performed before radiation and 1 week after the last radiation fraction. Isolated salivary gland acini were stimulated with either carbachol or adrenaline. Ca(2+) influx in response to the stimulation with these agonists was measured using laser scanning confocal microscopy. The uptake of activity and the excretion fraction of the parotid glands were significantly reduced after radiation, but lidocaine had a protective effect. Saliva total protein concentration was not altered after radiation. For isolated acini, Ca(2+) influx in response to stimulation with carbachol, but not adrenaline, was impaired after irradiation; lidocaine pretreatment attenuated this effect. Lidocaine has a radioprotective effect on the capacity of muscarinic agonist-induced water secretion in irradiated salivary glands

"Stars in der Manege?" Demokratietheoretische Überlegungen zur Dynamik partizipativer Forschung

Participatory methods aim to democratize and critique societies. However, their understanding of democracy has never been questioned. It is crucial to undertake such an analysis in order to fullyrecognize the critical potential of research  employing a participatory approach. Looking at participatory research we raise the following questions: Who are the real “stars” within participatory research and why? Who is participating and for what reasons, to what extent of time and at which phase of the research process? We argue that participatory research can only reach its full potential if one applies for example insights of democracy theory to it. In our approach we reject conceptions of democracy that are based on one-sided majorities and polarizations of power. We see the essential indicator for participatory research of high quality in its capability to question power relations and power distributions within the socialarena. This implies that participatory research maintains a critical watch on the reciprocity between researchers and research participants.. It further calls for a transparent method and the possibility for different parties to contribute in order to render the research productive for everybody involved.URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs120140Los métodos participativos buscan democratizar y criticar a las sociedades. Sin embrago, su entendimiento de la democracia nunca ha sido cuestionada. Es crucial emprender este análisis para poder reconocer completamente el potencial crítico de investigaciones que utilizan un enfoque participativo. Al mirar la investigación participativa nos surgen las siguientes preguntas: ¿Quiénes son las "estrellas" verdaderas dentro de la investigación participativa y por qué? ¿quién está participando y por qué razones?, ¿hasta cuándo y en qué fase del proceso de investigación? Planteamos que la investigación participativa solo puede alcanzar su potencial más alto si uno aplica, por ejemplo, las ideas de la teoría de la democracia. En nuestro enfoque rechazamos las concepciones de democracia basadas en mayorías unilaterales y polarizaciones del poder. Vemos el indicador esencial de la investigación participativa de alta calidad en su capacidad para cuestionar relaciones de poder y distribuciones de poder dentro de la arena social. Esto implica que la investigación participativa mantiene una visión crítica sobre la reciprocidad entre investigadores y participantes de una investigación. Se convoca, así, a un método transparente y la posibilidad de que diferentes partidos contribuyan a realizar una investigación productiva para todos los involucrados.URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs120140Partizipative Forschung hat einen demokratisierenden und damit zugleich einen gesellschaftskritischen Anspruch. Allerdings ist von den Anfängen der Aktionsforschung in den 1970er Jahren bis heute kaum reflektiert worden, welches Demokratieverständnis partizipativen Ansätzen zugrunde liegt: Wer partizipiert aus welchen Gründen, in welchem Umfang und zu welchem Zeitpunkt am Forschungsprozess? Wie stellen sich Machtverhältnisse zwischen den unterschiedlichen AkteurInnen dar? Wer sind die eigentlichen "Stars" in der Manege partizipativer qualitativer Forschung? Unter Hinzuziehung unterschiedlicher demokratietheoretischer Überlegungen wollen wir aufzeigen, wie der gesellschaftskritische Anspruch partizipativer Forschung nicht nur formuliert, sondern auch in der Praxis eingelöst werden kann.URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs12014

"Fragend schreiten wir voran" – eine Replik auf die Altvorderen der qualitativen Sozialforschung

Las reflexiones de REICHERTZ sobre el desarollo de la investigación cualitativa durante la Reunión de Berlín sobre Métodos de Investigación Cualitativa (http://www.berliner-methodentreffen.de/) en 2009 han conducido a las siguientes preguntas centrales: ¿Estamos enfrentando el fin de la investigación social crítica? ¿Se correlaciona este fin posible con una masa acrítica de científicos jóvenes? En su respuesta a los antepasados de la investigación cualitativa, los autores aquí presentes favorecen la destrucción de un pensamiento bipolar sobre estos temas y apoyan un giro híbrido. Ese giro híbrido apoya la prueba mediante una actitud del investigador fundamentalmente reflexiva, deconstructiva y de mente abierta. Usando el ejemplo de la etnografía y de los estudios degéenro, demostramos que, en efecto, hay oportunidades para el futuro de la investigación social crítica: Este enfoque tendria lugar más allá de los esclavos de la investigación a contrato controlada por el mercado y adelante de los caracteres del salón de la fama eterno de las ciencias sociales. URN: urn:nbn:de:0114-fqs0903306REICHERTZ' reflections on the development of qualitative research during the Berlin Meeting on Qualitative Research Methods in 2009 (http://www.berliner-methodentreffen.de/) have led to the following central questions: Are we facing the end of critical social research? Is this possible end correlated with an uncritical mass of young scientists? In their reply to the ancestors of qualitative research the present authors advocate the abolition of a bipolar thinking about the issues and support a hybrid turn, standing the test through a fundamentally open-minded, reflexive, and deconstructive researcher`s attitude. Using the example of ethnography and gender studies we show that there are indeed opportunities for the future of critical social research: This approach would take place beyond the slaves of market-controlled contract research and ahead of the characters of the eternal hall of fame of social research. URN: urn:nbn:de:0114-fqs0903306Angestoßen durch die von Jo REICHERTZ dargelegten Einschätzungen zur Entwicklung qualitativer Sozialforschung hat das Berliner Methodentreffen Qualitative Forschung 2009 (http://www.berliner-methodentreffen.de/) folgende zentrale Fragen aufgeworfen: Stehen wir vor dem Ende der kritischen Sozialforschung? Kann ihr mögliches Finitum mit einer unkritischen Masse junger Nachwuchsforscher/innen in Verbindung gebracht werden? Wir plädieren in unserer Replik auf die "Altvorderen" der qualitativen Sozialforschung für eine Auflösung bipolar-konstruierter Denkschemata und einen hybriden Turn, der sich durch eine grundsätzlich offene, reflexive und dekonstruierende Haltung der Forschenden zu bewähren hat. Am Beispiel der Ethnografie und der Geschlechterforschung versuchen wir zu zeigen, dass es durchaus Potenziale für eine Zukunft kritischer Sozialforschung gibt, jenseits von Sklav/innen marktgesteuerter Auftragsforschung und den Charakterdarsteller/innen der ewigen Hall of Fame der Sozialforschung.
