Das Biobankgeheimnis : Schutz der Persönlichkeitsrechte in der biomedizinischen Forschung

Biobanken sind Sammlungen von Körpersubstanzen, die mit umfangreichen gesundheits- und lebensstilbezogenen sowie geneologischen Daten ihrer Spender verknüpft sind. Sie dienen der Erforschung weit verbreiteter Krankheiten. Diese sog. Volkskrankheiten sind multifaktoriell bedingte Krankheiten. Dies bedeutet, dass diese Krankheiten das Ergebnis eines komplizierten Zusammenspiels von umwelt- und verhaltensrelevanten Faktoren mit individuellen genetischen Prädispositionen sind. Forschungen im Bereich von Pharmakogenomik und Pharmakogenetik untersuchen den Einfluss von Genen und Genexpressionen auf die individuelle Wirksamkeit von Medikamenten sowie auf die Entstehung ungewollter Nebenwirkungen und könnten so den Weg zu einer individualisierten Medizin ebnen. Menschliches Material ist ein wichtiger Bestandteil dieser Forschungen und die Nachfrage nach Sammlungen, die Proben mit Daten verknüpfen, steigt. Einerseits sehen Mediziner in Biobanken eine Chance für die Weiterentwicklung der medizinischen Forschung und des Gesundheitswesens. Andererseits lösen Biobanken auch Ängste und Misstrauen aus. Insbesondere wird befürchtet, dass Proben und Daten unkontrolliert verwendet werden und sensible Bereiche des Persönlichkeitsrechts und der persönlichen Identität betroffen sind. Diese Gefahren und Befürchtungen sind nicht neu, sondern bestanden schon in der Vergangenheit bei jeglicher Form der Spende von Körpersubstanzen. Neu ist aber der Umfang an Informationen, der durch die Genanalyse entsteht und den Spender in ganz besonderer Weise betreffen kann. Bei der Speicherung und Nutzung der medizinischen und genetischen Daten ergibt sich somit ein Spannungsfeld insbesondere zwischen dem Recht der betroffenen Datenspender auf informationelle Selbstbestimmung und den Forschungsinteressen der Datennutzer. Im Kern dreht sich die ethisch-rechtliche Bewertung der Biobanken um die Frage, ob diese Forschung zusätzliche Regeln braucht, und falls ja, wie umfassend diese sein müssten. Im Zentrum dieser Diskussion stehen dabei v.a. ethische Fragen im Zusammenhang mit der informierten Einwilligung, dem Datenschutz, der Wiederverwendung von Proben und Daten, der Information der Spender über Forschungsergebnisse und der Nutzungsrechte an den Daten. Ziel dieser Arbeit ist es, vor dem Hintergrund des Verfassungsrechts, insbesondere dem Recht auf informationelle Selbstbestimmung, das Datenschutzrecht im Hinblick auf die Risiken zu untersuchen, die sich aus der Speicherung, Verarbeitung und Kommunikation von persönlichen genetischen Informationen beim Aufbau von Biobanken ergeben. Daraus ergibt sich die weitere Untersuchung, ob und unter welchen Voraussetzungen die sich entgegenstehenden Interessen und Rechte aus verfassungsrechtlichem Blickwinkel in Einklang zu bringen sind. Eine wesentliche Frage lautet, ob die bisherigen rechtlichen Rahmenbedingungen ausreichen, um den Schutz der gespeicherten höchstpersönlichen Daten und zugleich ihre angemessene Nutzung zu gewährleisten. Das Thema ist interdisziplinär im Schnittfeld von Datenschutz, Verfassungsrecht sowie Rechts- und Medizinethik angelegt.

Software als Schutzgegenstand des Europäischen Urheberrechts

After 20 years of silence, two recent references from the Czech Republic (Bezpečnostní softwarová asociace, Case C-393/09) and from the English High Court (SAS Institute, Case C-406/10) touch upon several questions that are fundamental for the extent of copyright protection for software under the Computer Program Directive 91/25 (now 2009/24) and the Information Society Directive 2001/29. In Case C-393/09, the European Court of Justice held that “the object of the protection conferred by that directive is the expression in any form of a computer program which permits reproduction in different computer languages, such as the source code and the object code.” As “any form of expression of a computer program must be protected from the moment when its reproduction would engender the reproduction of the computer program itself, thus enabling the computer to perform its task,” a graphical user interface (GUI) is not protected under the Computer Program Directive, as it does “not enable the reproduction of that computer program, but merely constitutes one element of that program by means of which users make use of the features of that program.” While the definition of computer program and the exclusion of GUIs mirror earlier jurisprudence in the Member States and therefore do not come as a surprise, the main significance of Case C-393/09 lies in its interpretation of the Information Society Directive. In confirming that a GUI “can, as a work, be protected by copyright if it is its author’s own intellectual creation,” the ECJ continues the Europeanization of the definition of “work” which began in Infopaq (Case C-5/08). Moreover, the Court elaborated this concept further by excluding expressions from copyright protection which are dictated by their technical function. Even more importantly, the ECJ held that a television broadcasting of a GUI does not constitute a communication to the public, as the individuals cannot have access to the “essential element characterising the interface,” i.e., the interaction with the user. The exclusion of elements dictated by technical functions from copyright protection and the interpretation of the right of communication to the public with reference to the “essential element characterising” the work may be seen as welcome limitations of copyright protection in the interest of a free public domain which were not yet apparent in Infopaq. While Case C-393/09 has given a first definition of the computer program, the pending reference in Case C-406/10 is likely to clarify the scope of protection against nonliteral copying, namely in how far the protection extends beyond the text of the source code to the design of a computer program and where the limits of protection lie as regards the functionality of a program and mere “principles and ideas.” In light of the travaux préparatoires, it is submitted that the ECJ is also likely to grant protection for the design of a computer program, while excluding both the functionality and underlying principles and ideas from protection under the European copyright directives.

Creative Commons licences and design Are the two compatible?

This article analyses whether Creative Commons licences are applicable to and compatible with design. The first part focuses on the peculiar and complex nature of a design, which can benefit from a copyright and a design protection. This shows how it can affect the use of Creative Commons licences. The second and third parts deal with a specific case study. Some Internet platforms have recently emerged that offer users the possibility to download blueprints of design products in order to build them. Designers and creative users are invited to share their blueprints and creations under Creative Commons licences. The second part of the article assesses whether digital blueprints can be copyrightable and serve as the subject matter of Creative Commons licences, while the last part assesses whether the right to reproduce the digital blueprint, as provided by Creative Commons licences, extends to the right to build the product.

Privacy in the Post-NSA Era: Time for a Fundamental Revision?

Big Brother Watch and others have filed a complaint against the United Kingdom under the European Convention on Human Rights about a violation of Article 8, the right to privacy. It regards the NSA affair and UK-based surveillance activities operated by secret services. The question is whether it will be declared admissible and, if so, whether the European Court of Human Rights will find a violation. This article discusses three possible challenges for these types of complaints and analyses whether the current privacy paradigm is still adequate in view of the development known as Big Data.

Oblivion, Erasure and Forgetting in the Digital Age

In light of the recent European Court of Justice ruling (ECJ C-131/12, Google Spain v Spanish Data Protection Agency),the “right to be forgotten” has once again gained worldwide media attention. Already in 2012, whenthe European Commission proposed aright to be forgotten,this proposal received broad public interest and was debated intensively. Under certain conditions, individuals should thereby be able todelete personal data concerning them. More recently – in light of the European Parliament’s approval of the LIBE Committee’samendments onMarch 14, 2014 – the concept seems tobe close to its final form.Although it remains, for the most part,unchanged from the previously circulated drafts, it has beenre-labelled as a“right of erasure”. This article argues that, despite its catchy terminology, the right to be forgotten can be understood as a generic term, bringing together existing legal provisions: the substantial right of oblivion and the rather procedural right to erasure derived from data protection. Hereinafter, the article presents an analysis of selected national legal frameworks and corresponding case law, accounting for data protection, privacy, and general tort law as well as defamation law. This comparative analysis grasps the practical challenges which the attempt to strengthen individual control and informational self-determination faces. Consequently, it is argued that narrowing the focus on the data protection law amendments neglects the elaborate balancing of conflicting interests in European legal tradition. It is shown thatthe attemptto implement oblivion, erasure and forgetting in the digital age is a complex undertaking.

A manifesto for an e-lending limitation in copyright

In the European Union, lending is an exclusive right for copyright and related rights, but Member States can transform public lending to a right of remuneration and even exempt some establishments from any payment. The making available of works online is not covered by the public lending right regime of the Rental and Lending Directive but is considered as an act of making available governed by the InfoSoc Directive. As a consequence, libraries are currently not allowed to digitally transmit works to their patrons as lending, but have entered into licenses with publishers to develop an offer of lending of e-books, also called e-lending, with the intermediation of dedicated platforms operated by commercial actors. Compared to physical lending, e-lending is not based on ownership of the book by libraries but on its provision by this intermediary. This paper discusses how the objective of enabling libraries to engage in e-lending should be achieved, and what is the proper dividing line between a market-based solution, as developing today, and a limitation to exclusive rights. The impact of an extension of the public lending right to e-lending should be assessed, but not based on a criterion of direct substitution of a book on loan at the library to a book bought at a retailer. By definition, libraries are substitutes to normal trade. Instead, the overall effect of lending to the commercialisation of books and other works should be verified. Particular conditions for a limitation in favour of lending are also addressed, and notably the modalities of lending (a limited duration, one simultaneous user per title, …), not to make e-lending through libraries easier and preferable to the normal acquisition of an e-book. This paper argues in favour of some and controlled extension of the public lending right to cover the lending of e-books and other digital content. For the role of libraries is essential in providing access to works and culture to readers who would or could not rely only on normal acquisition of books or other items on the market, to works that are not provided by the market, and to material for research. Libraries are a third sector providing access to works, aside the market and non-market exchanges between individuals. This role should not lose its relevance in the digital context, or it would culturally impoverish future generations of readers.

Herbrand Theorems for Substructural Logics

Herbrand and Skolemization theorems are obtained for a broad family of first-order substructural logics. These logics typically lack equivalent prenex forms, a deduction theorem, and reductions of semantic consequence to satisfiability. The Herbrand and Skolemization theorems therefore take various forms, applying either to the left or right of the consequence relation, and to restricted classes of formulas.

Geochemical synthesis for the Effingen Member in boreholes at Oftringen, Gösgen and Küttigen

The Effingen Member is a low-permeability rock unit of Oxfordian age (ca. 160 Ma) that occurs across northern Switzerland. It comprises sandy calcareous marls and (argillaceous) limestones. This report describes the hydrogeochemistry, mineralogy and supporting physical properties of the Effingen Member in three boreholes in the Jura-Südfuss area: Oftringen, Gösgen and Küttigen, where it is 220–240 m thick. The top of the Effingen Member is at 420, 66 and 32 m depths at the three sites. Core materials are available from Oftringen and Gösgen, whereas information from Küttigen is limited to cuttings, in-situ hydrogeological testing and geophysical logging. Hydrogeological boundaries of the Effingen Member vary between locations. Ground-water flows were identified during drilling at the top (Geissberg Member), but not at the base, of the Effingen Member at Oftringen, at the base (Hauptrogenstein Formation) of the Effingen Member at Gösgen, and in a limestone layer (Gerstenhübel unit) within the Effingen Member at Küttigen. The marls and limestones of the Effingen Member have carbonate contents of 46–91 wt.-% and clay-mineral contents of 5–37 wt.-%. Pyrite contents are up to 1.6 wt.-%, but no sulphate minerals were detected by routine analyses. Clay minerals are predominantly mixed-layer illite-smectite, illite and kaolinite, with sporadic traces of chlorite and smectite. Veins filled with calcite ± celestite occur through the Effingen Member at Oftringen but not at Gösgen or Küttigen. They formed at 50–70 ºC from externally derived fluids, probably of Miocene age. Water contents are 0.7–4.2 wt.-%, corresponding to a water-loss porosity range of 1.9–10.8 vol.-%. Specific surface areas, measured by the BET method, are 2–30 m2/g, correlating with clay-mineral contents. Water activity has been measured and yielded surprisingly low values down to 0.8. These cannot be explained by pore-water salinity alone and include other effects, such as changes in the fabric due to stress release or partial saturation. Observed variations in measurements are not fully understood. Cation exchange capacity (CEC) and exchangeable cation populations have been studied by the Ni-en method. CEC, derived from the consumption of the index cation Ni, is 9–99 meq/kgrock at a solid:liquid ratio of 1, correlating with the clay-mineral content. Cation concentrations in Ni-en extract solutions are in the order Na+≥Ca2+>Mg2+>K+>Sr2+. However, the analytical results from the Ni-en extractions have additional contributions from cations originating from pore water and from mineral dissolution reactions that occurred during extraction, and it was not possible to reliably quantify these contributions. Therefore, in-situ cation populations and selectivity coefficients could not be derived. A suite of methods have been used for characterising the chemical compositions of pore waters in the Effingen Member. Advective displacement was used on one sample from each Oftringen and Gösgen and is the only method that produces results that approach complete hydrochemical compositions. Aqueous extraction was used on core samples from these two boreholes and gives data only for Cl- and, in some cases, Br-. Out-diffusion was used on core samples from Oftringen and similarly gives data for Cl- and Br- only. For both aqueous extraction and out-diffusion, reaction of the experimental water with rock affected concentrations of cations, SO42 and alkalinity in experimental solutions. Another method, centrifugation, failed to extract pore water. Stable isotope ratios (δ18O and δ2H) of pore waters in core samples from Oftringen were analysed by the diffusive exchange method and helium contents of pore water in Oftringen samples were extracted for mass spectrometric analysis by quantitative outgassing of preserved core samples. Several lines of evidence indicate that drillcore samples might not have been fully saturated when opened and subsampled in the laboratory. These include comparisons of water-loss porosities with physical porosities, water-activity measurements, and high contents of dissolved gas as inferred from ground-water samples. There is no clear proof of partial saturation and it is unclear whether this might represent in-situ conditions or is due to exsolution of gas due to the pressure release since drilling. Partial saturation would have no impact on the recalculation of pore-water compositions from aqueous extraction experiments using water-loss porosity data. The largest uncertainty in the pore-water Cl- concentrations recalculated from aqueous extraction and out-diffusion experiments is the magnitude of the anion-accessible fraction of water-loss porosity. General experience of clay-mineral rich formations suggests that the anion-accessible porosity fraction is very often about 0.5 and generally in a range of 0.3 to 0.6 and tends to be inversely correlated with clay-mineral contents. Comparisons of the Cl- concentration in pore water obtained by advective displacement with that recalculated from aqueous extraction of an adjacent core sample suggests a fraction of 0.27 for an Oftringen sample, whereas the same procedure for a Gösgen sample suggests a value of 0.64. The former value for anion-accessible porosity fraction is presumed to be unrepresentative given the local mineralogical heterogeneity at that depth. Through-diffusion experiments with HTO and 36Cl- suggest that the anion-accessible porosity fraction in the Effingen Member at Oftringen and Gösgen is around 0.5. This value is proposed as a typical average for rocks of the Effingen Member, bearing in mind that it varies on a local scale in response to the heterogeneity of lithology and pore-space architecture. The substantial uncertainties associated with the approaches to estimating anion-accessible porosity propagate into the calculated values of in-situ pore-water Cl- concentrations. On the basis of aqueous extraction experiments, and using an anion-accessible porosity fraction of 0.5, Cl- concentrations in the Effingen Member at Oftringen reach a maximum of about 14 g/L in the centre. Cl- decreases upwards and downwards from that, forming a curved depth profile. Cl- contents in the Effingen Member at Gösgen increase with depth from about 3.5 g/L to about 14 g/L at the base of the cored profile (which corresponds to the centre of the formation). Out-diffusion experiments were carried out on four samples from Oftringen, distributed through the Effingen Member. Recalculated Cl- concentrations are similar to those from aqueous extraction for 3 out of the 4 samples, and somewhat lower for one sample. Concentrations of other components, i.e. Na+, K+, Ca2+, Mg2+, Sr2+, SO42- and HCO3- cannot be obtained from the aqueous extraction and out-diffusion experimental data because of mineral dissolution and cation exchange reactions during the experiments. Pore-water pH also is not constrained by those extraction experiments. The only experimental approach to obtain complete pore-water compositions for samples from Oftringen and Gösgen is advective displacement of pore water. The sample from Oftringen used for this experiment is from 445 m depth in the upper part of the Effingen Member and gave eluate with 16.5 g/L Cl- whereas aqueous extraction from a nearby sample indicated about 9 g/L Cl-. The sample from Gösgen used for advective displacement is from 123 m depth in the centre of the Effingen Member sequence and gave eluate with about 9 g/L Cl- whereas aqueous extraction gave 11.5 g/L Cl-. In both cases the pore waters have Na-(Ca)-Cl compositions and SO42- concentrations of about 1.1 g/L. The Gösgen sample has a Br/Cl ratio similar to that of sea water, whereas this ratio is lower for the Oftringen sample. Taking account of uncertainties in the applied experimental approaches, it is reasonable to place an upper limit of ca. 20 g/L on Cl- concentration for pore water in the Effingen Member in this area. There are major discrepancies between pore-water SO42- concentrations inferred from aqueous extraction or out-diffusion experiments and those obtained from advective displacement in both the Oftringen and Gösgen cases. A general conclusion is that all or at least part of the discrepancies are attributable to perturbation of the sulphur system and enhancement of SO42- by sulphate mineral dissolution and possibly minor pyrite oxidation during aqueous extraction and out-diffusion. Therefore, data for SO42- calculated from those pore-water sampling methods are considered not to be representative of in-situ conditions. A reference pore-water composition was defined for the Effingen Member in the Jura Südfuss area. It represents the probable upper limits of Cl- contents and corresponding anion and cation concentrations that are reasonably constrained by experimental data. Except for Cl- and possibly Na+ concentrations, this composition is poorly constrained especially with respect to SO42- and Ca2+ concentrations, and pH and alkalinity. Stable isotope compositions, δ18O and δ2H, of pore waters in the Effingen Member at Oftringen plot to the right of the meteoric water line, suggesting that 18O has been enriched by water-rock exchange, which indicates that the pore waters have a long residence time. A long residence time of pore water is supported by the level of dissolved 4He that has accumulated in pore water of the Effingen Member at Oftringen. This is comparable with, or slightly higher than, the amounts of 4He in the Opalinus Clay at Benken. Ground waters were sampled from flowing zones intersected by boreholes at the three locations. The general interpretation is that pore waters and ground-water solutes may have similar origins in Mesozoic and Cenozoic brackish-marine formations waters, but ground-water solutes have been diluted rather more than pore waters by ingress of Tertiary and Quaternary meteoric waters. The available hydrochemical data for pore waters from the Effingen Member at these three locations in the Jura-Südfuss area suggest that the geochemical system evolved slowly over geological periods of time, in which diffusion was an important mechanism of solute transport. The irregularity of Cl- and δ18O profiles and spatial variability of advective ground-water flows in the Malm-Dogger system suggests that palaeohydrogeological and hydrochemical responses to changing tectonic and surface environmental conditions were complex.

The Swiss Schools have been Governed by Local Lay Authorities

After the introduction of the liberal-democratic constitutions in the Swiss cantons in the first half of the 1830ies the grid of existing schools has been systemized and broadly expanded. The school systems have ever since been characterized by one key element: a special local authority type called „Schulkommission“ or „Schulpflege“. They take the form of committees consisting of laymen that are appointed by democratic elections like all the other executive bodies on the different federal levels in Switzerland. When it comes to their obligations and activities these community level school committees conform very much to the school boards in the American and Canadian school systems. They are accountable for the selection and supervision of the teachers. They approve decisions about the school careers of pupils and about curricular matters like the choice of school books. Normally their members are elected by the local voters for four year terms of office (reelection remains possible) and with regard to pedagogics they normally are non-professionals. The board members are responsible for classes and teachers assigned to them and they have to go to see them periodically. These visitations and the board meetings each month together with the teachers enable the board members to attain a deep insight into what happens in their schools over the course of their term of office. But they are confronted as laymen with a professional teaching staff and with educational experts in the public administration. Nevertheless this form of executive power by non-professionals is constitutive for the state governance in the Swiss as well as in other national political environments. It corresponds to the principles of subsidiarity and militia and therefore allows for a strong accentuation of liberty and the right of self-determination, two axioms at the very base of democratic federalist ideology. This governance architecture with this strong accent on local anchorage features substantial advantages for the legitimacy and acceptability of political and administrative decisions. And this is relevant especially in the educational area because the rearing of the offspring is a project of hope and, besides, quite costly. In the public opinion such supervision bodies staffed by laymen seem to have certain credibility advances in comparison with the professional administration. They are given credit to be capable of impeding the waste of common financial resources and of warranting the protection and the fostering of the community’s children at once. Especially because of their non-professional character they are trusted to be reliably immune against organizational blindness and they seem to be able to defend the interests of the local community against the standardization and centralization aspirations originating from the administrational expertocracy. In the paper these common rationales will be underpinned by results of a comprehensive historical analysis of the Session protocols of three Bernese school commissions from 1835 to 2005.

Skolemization for Substructural Logics

The usual Skolemization procedure, which removes strong quantifiers by introducing new function symbols, is in general unsound for first-order substructural logics defined based on classes of complete residuated lattices. However, it is shown here (following similar ideas of Baaz and Iemhoff for first-order intermediate logics in [1]) that first-order substructural logics with a semantics satisfying certain witnessing conditions admit a “parallel” Skolemization procedure where a strong quantifier is removed by introducing a finite disjunction or conjunction (as appropriate) of formulas with multiple new function symbols. These logics typically lack equivalent prenex forms. Also, semantic consequence does not in general reduce to satisfiability. The Skolemization theorems presented here therefore take various forms, applying to the left or right of the consequence relation, and to all formulas or only prenex formulas.

Fray Alonso de la Veracruz : ensayo de síntesis

El artículo presenta una síntesis de la obra escrita de Veracruz y, en parte, también de su acción. De tal modo, se exponen sus escritos filosóficos, en materia de lógica (Recognitio Summularum y Dialectica Resolutio) y de filosof��a natural (Physica Speculatio), y las relecciones en las que se ocupó de los títulos de la conquista y la condición de los indios (De dominio infidelium y De decimis). También es propósito del trabajo proporcionar, a quien quiera continuar con el tema, una guía de buena parte de la abundante literatura secundaria que se ha ocupado de Fray Alonso de la Veracruz. Veracruz es un importante representante de la escolástica novohispana del siglo XVI, y simboliza el comienzo del trasplante filosófico que bajo el signo de la escolástica se extendería en Iberoamérica hasta el siglo XVIII y parte del XIX.

El impacto de la Ley de Servicios de Comunicación Audiovisual en los diarios mendocinos Los Andes y Uno : un análisis desde la intencionalidad editorial

En base al modelo teórico metodológico de la intencionalidad editorial, que sostiene que el periodismo es objetivo (en tanto remite a fuentes), y parcial (toma de posición), analizamos la cobertura realizada por los diarios Los Andes y UNO sobre la Ley de Servicios de Comunicación Audiovisual. La hipótesis fue que los diarios locales construyeron, a través de piezas periodísticas, un sentido común que respondió a sus intereses corporativos en detrimento del derecho humano a la comunicación. El análisis consistió en un observatorio de medios que combinó metodología cuantitativa y cualitativa, desde el 27 de agosto al 11 de octubre de 2009.
