    Flexible copyright: the law and economics of introducing an open norm in the Netherlands

    This study analyses the law and economics of introducing flexibility in the system of exceptions and limitations in Dutch copyright law. Such flexibility would exist in an open norm, on the basis of which the courts can decide whether certain uses of copyrighted material are permissible or not, instead of explicitly defining this in the law. First, it assesses problem areas where the lack of flexibility creates legal disputes and potential barriers to innovation and commercialisation. Second, it analyses the economic rationale and economic effects of introducing flexibility. The study was commissioned by the Dutch Ministry of Economic Affairs, Agriculture & Innovation. Research methods used are literature review and in-depth interviews. The study includes a case study of Israel, where a fair use exception was introduced in the Copyright Act in 2007. Exceptions and limitations in the current copyright system are meant to balance the protection granted to rights owners with the public interest’s need to make certain unauthorized uses. However, this report identified a number of situations that do not fit well within the current set of exceptions and limitations and attributes this to a lack of flexibility. Among these uses are the activities of search engines, the use of works in User Created Content, cloud computing, data mining, distance learning, and transformative uses by, for instance, documentary filmmakers. Several of these problem areas have given rise to court proceedings with varying outcomes. The interpretation given by courts to existing exceptions and limitations - such as the quotation right, the exception for transient and incidental copying, the private copying exception, and the incidental use exception - is usually too narrow to respond to new technological developments, new developments in the creation process, or new commercialisation models. These types of uses generally do not ‘fit’ the narrowly defined exceptions and limitations and therefore lack legal basis. The same is true for things not yet invented. Because the law is not flexible in itself, courts have increasingly found inventive ways to create legal space for uses that are not covered by the exhaustive list of exceptions. In these cases flexibility with specific evaluation criteria could have been more satisfactory from a legal perspective. Flexibility could be obtained by introducing an open norm in the copyright system. This report defines such an open norm for the purpose of analysing the effects of more flexibility in copyright law. The norm has two main properties. First, it would coexist with the exhaustive list of exceptions and limitations in the current Dutch Copyright Act. Second, a use of a work would only benefit from the open norm if it passes the so-called three-step test, which takes the interests of the author or right holder into account. The first category of economic effects of introducing an open norm is that for some known uses that otherwise require licensing, the open norm would allow unlicensed use. Thispotentially reduces the reward to the creator of a work and therefore decreases the incentive to create. By contrast, it is also likely to reduce the creator’s costs of using another work as an input when producing a new work, and therefore to increase the incentive to create. It is difficult to predict which of these two opposing effects ultimately turns the scale in specific markets. Traditional creators generally worry about the negative effect on their reward and seem to believe that the first effect dominates. For businesses that use large numbers of protected works as an input for their services, such as Google, the opposite is true. They emphasise the benefits of reduced input costs and are likely to improve their legal position with an open norm. Collective rights management organisations in turn fear that their bargaining power vis-à-vis users like UCC-platforms, such as YouTube, would suffer from an open norm. However, given the design of the open norm, it is unlikely that rewards for creators are significantly affected. The application of the open norm by the courts tests for adverse effects on the business model of the rights holder (the previously mentioned three-step test). In case of severe adverse effects on the rights holder, the open norm does not apply. The shift in bargaining power from rights holders to user (platforms) is limited to cases that are currently licensed and where parties are sufficiently confident that the use benefits from the open norm. The second category of economic effects of introducing an open norm is that the legal delineation between infringement and permissible use becomes capable of accommodating developments in technology and society. This enables entrepreneurs to develop new products and services that rely on currently unforeseen use of protected material. On the downside, flexibility may reduce legal certainty in the short run, until jurisprudence on the practice of flexible copyright has developed. The countries that have recently introduced an open norm in their copyright laws have not produced any ex-ante or ex-post studies on the magnitude of these economic effects. The case study of fair use in Israel shows that the change may decrease legal certainty in the short run (as case law needs time to develop), but improve legal certainty in the longer run, as the legal position of acts that do not ‘fit’ a rigid system with an exhaustive list of static exceptions is being clarified. In sum, the main effects of introducing an open norm seem to be of a legal nature: it changes the legal position of some businesses and therefore affects the costs these businesses make to comply with copyright. ‘Tomorrow’s inventions’ are likely to be facilitated by an open norm. Since most businesses seem currently not chilled by the lack of flexibility, the effect on products and services available in the market is likely to be secondary to the legal effects

    Technical debt and waste in non-functional requirements documentation:an exploratory study

    Get PDF
    Background: To adequately attend to non-functional requirements (NFRs), they must be documented; otherwise, developers would not know about their existence. However, the documentation of NFRs may be subject to Technical Debt and Waste, as any other software artefact. Aims: The goal is to explore indicators of potential Technical Debt and Waste in NFRs documentation. Method: Based on a subset of data acquired from the most recent NaPiRE (Naming the Pain in Requirements Engineering) survey, we calculate, for a standard set of NFR types, how often respondents state they document a specific type of NFR when they also state that it is important. This allows us to quantify the occurrence of potential Technical Debt and Waste. Results: Based on 398 survey responses, four NFR types (Maintainability, Reliability, Usability, and Performance) are labelled as important but they are not documented by more than 22% of the respondents. We interpret that these NFR types have a higher risk of Technical Debt than other NFR types. Regarding Waste, 15% of the respondents state they document NFRs related to Security and they do not consider it important. Conclusions: There is a clear indication that there is a risk of Technical Debt for a fixed set of NFRs since there is a lack of documentation of important NFRs. The potential risk of incurring Waste is also present but to a lesser extent

    Selection of microsatellite markers for bladder cancer diagnosis without the need for corresponding blood

    Get PDF
    Microsatellite markers are used for loss-of-heterozygosity, allelic imbalance and clonality analyses in cancers. Usually, tumor DNA is compared to corresponding normal DNA. However, normal DNA is not always available and can display aberrant allele ratios due to copy number variations in the genome. Moreover, stutter peaks may complicate the analysis. To use microsatellite markers for diagnosis of recurrent bladder cancer, we aimed to select markers without stutter peaks and a constant ratio between alleles, thereby avoiding the need for a control DNA sample. We investigated 49 microsatellite markers with tri- and tetranucleotide repeats in regions commonly lost in bladder cancer. Based on analysis of 50 blood DNAs the 12 best performing markers were selected with few stutter peaks and a constant ratio between peaks heights. Per marker upper and lower cut off values for allele ratios were determined. LOH of the markers was observed in 59/104 tumor DNAs. We then determined the sensitivity of the marker panel for detection of recurrent bladder cancer by assaying 102 urine samples of these patients. Sensitivity was 63% when patients were stratified for LOH in their primary tumors. We demonstrate that up-front selection of microsatellite markers obliterates the need for a corresponding blood sample. For diagnosis of bladder cancer recurrences in urine this significantly reduces costs. Moreover, this approach facilitates retrospective analysis of archival tumor samples for allelic imbalance

    Public trust and 'ethics review' as a commodity: the case of Genomics England Limited and the UK's 100,000 genomes project.

    Get PDF
    The UK Chief Medical Officer's 2016 Annual Report, Generation Genome, focused on a vision to fully integrate genomics into all aspects of the UK's National Health Service (NHS). This process of integration, which has now already begun, raises a wide range of social and ethical concerns, many of which were discussed in the final Chapter of the report. This paper explores how the UK's 100,000 Genomes Project (100 kGP)-the catalyst for Generation Genome, and for bringing genomics into the NHS-is negotiating these ethical concerns. The UK's 100 kGP, promoted and delivered by Genomics England Limited (GEL), is an innovative venture aiming to sequence 100,000 genomes from NHS patients who have a rare disease, cancer, or an infectious disease. GEL has emphasised the importance of ethical governance and decision-making. However, some sociological critique argues that biomedical/technological organisations presenting themselves as 'ethical' entities do not necessarily reflect a space within which moral thinking occurs. Rather, the 'ethical work' conducted (and displayed) by organisations is more strategic, relating to the politics of the organisation and the need to build public confidence. We set out to explore whether GEL's ethical framework was reflective of this critique, and what this tells us more broadly about how genomics is being integrated into the NHS in response to the ethical and social concerns raised in Generation Genome. We do this by drawing on a series of 20 interviews with individuals associated with or working at GEL

    Get PDF
    INTRODUCTION: Foreign bodies' entrapments in the mandibular and submandibular regions are quite common. CASE PRESENTATION: We report an unusual case of foreign body (amalgam filling) entrapment over the mental foramen causing dysaesthesia in the distribution of the mental nerve. An interesting sign was blue discoloration of the overlaying oral mucosa which was interpreted as amalgam tattooing. CONCLUSION: Surgical removal of the foreign object eliminated the reported symptoms

    Rapid synthesis and enhancement in down conversion emission properties of BaAl2O4:Eu2+,RE3+ (RE3+=Y, Pr) nanophosphors

    [EN] BaAl2O4:Eu2+,RE3+ (RE3+=Y, Pr) down conversion nanophosphors were prepared at 600 °C by a rapid gel combustion technique in presence of air using boron as flux and urea as a fuel. A comparative study of the prepared materials was carried out with and without the addition of boric acid. The boric acid was playing the important role of flux and reducer simultaneously. The peaks available in the XPS spectra of BaAl2O4:Eu2+ at 1126.5 and 1154.8 eV was ascribed to Eu2+(3d5/2) and Eu2+(3d3/2) respectively which confirmed the presence of Eu2+ ion in the prepared lattice. Morphology of phosphors was characterized by tunneling electron microscopy. XRD patterns revealed a dominant phase characteristics of hexagonal BaAl2O4 compound and the presence of dopants having unrecognizable effects on basic crystal structure of BaAl2O4. The addition of boric acid showed a remarkable change in luminescence properties and crystal size of nanophosphors. The emission spectra of phosphors had a broad band with maximum at 490–495 nm due to electron transition from 4f65d1 → 4f7 of Eu2+ ion. The codoping of the rare earth (RE3+=Y, Pr) ions help in the enhancement of their luminescent properties. The prepared phosphors had brilliant optoelectronic properties that can be properly used for solid state display device applications.The authors gratefully recognize the financial support from the University Grant Commission (UGC), New Delhi [MRP-40-73/2011(SR)] and the European Commission through Nano CIS project (FP7-PEOPLE-2010-IRSES ref. 269279).Singh, D.; Tanwar, V.; Simantilke, AP.; Marí, B.; Kadyan, PS.; Singh, I.

    We explored the submarine portions of the Enriquillo–Plantain Garden Fault zone (EPGFZ) and the Septentrional–Oriente Fault zone (SOFZ) along the Northern Caribbean plate boundary using high-resolution multibeam echo-sounding and shallow seismic reflection. The bathymetric data shed light on poorly documented or previously unknown submarine fault zones running over 200 km between Haiti and Jamaica (EPGFZ) and 300 km between the Dominican Republic and Cuba (SOFZ). The primary plate-boundary structures are a series of strike-slip fault segments associated with pressure ridges, restraining bends, step overs and dogleg offsets indicating very active tectonics. Several distinct segments 50–100 km long cut across pre-existing structures inherited from former tectonic regimes or bypass recent morphologies formed under the current strike-slip regime. Along the most recent trace of the SOFZ, we measured a strike-slip offset of 16.5 km, which indicates steady activity for the past ~1.8 Ma if its current GPS-derived motion of 9.8 ± 2 mm a−1 has remained stable during the entire Quaternary.Depto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEpu

    Thrombotic gene polymorphisms and postoperative outcome after coronary artery bypass graft surgery

    <p>Abstract</p> <p>Background</p> <p>Emerging perioperative genomics may influence the direction of risk assessment and surgical strategies in cardiac surgery. The aim of this study was to investigate whether single nucleotide polymorphisms (SNP) affect the clinical presentation and predispose to increased risk for postoperative adverse events in patients undergoing coronary artery bypass grafting surgery (CABG).</p> <p>Methods</p> <p>A total of 220 patients undergoing first-time CABG between January 2005 and May 2008 were screened for factor V gene G1691A (FVL), prothrombin/factor II G20210A (PT G20210A), angiotensin I-converting enzyme insertion/deletion (ACE-ins/del) polymorphisms by PCR and Real Time PCR. End points were defined as death, myocardial infarction, stroke, postoperative bleeding, respiratory and renal insufficiency and event-free survival. Patients were compared to assess for any independent association between genotypes for thrombosis and postoperative phenotypes.</p> <p>Results</p> <p>Among 220 patients, the prevalence of the heterozygous FVL mutation was 10.9% (n = 24), and 3.6% (n = 8) were heterozygous carriers of the PT G20210A mutation. Genotype distribution of ACE-ins/del was 16.6%, 51.9%, and 31.5% in genotypes I/I, I/D, and D/D, respectively. FVL and PT G20210A mutations were associated with higher prevalence of totally occluded coronary arteries (p < 0.001). Furthermore the risk of left ventricular aneurysm formation was significantly higher in FVL heterozygote group compared to FVL G1691G (<it>p </it>= 0.002). ACE D/D genotype was associated with hypertension (<it>p </it>= 0.004), peripheral vascular disease (p = 0.006), and previous myocardial infarction (<it>p </it>= 0.007).</p> <p>Conclusions</p> <p>FVL and PT G20210A genotypes had a higher prevalence of totally occluded vessels potentially as a result of atherothrombotic events. However, none of the genotypes investigated were independently associated with mortality.</p

    Genes influencing coagulation and the risk of aneurysmal subarachnoid hemorrhage, and subsequent complications of secondary cerebral ischemia and rebleeding

    We investigated whether genes influencing coagulation are associated with the occurrence of aneurysmal subarachnoid hemorrhage (SAH) and with secondary cerebral ischemia and rebleeding in patients with aneurysmal SAH. Genotyping for factor V Leiden (G1691A), prothrombin G20210A, methylenetetetrahydrofolate reductase (MTHFR) C677T, factor XIII subunit A Val34Leu, Tyr204Phe and Pro564Leu, and factor XIII subunit B His95Arg was performed in 208 patients with aneurysmal SAH and in 925 controls. Secondary cerebral ischemia occurred in 49 (24%) patients and rebleeding in 28 (14%) during their clinical course of 3 months after the aneurysmal SAH. The risk of aneurysmal SAH was assessed as odds ratio (OR) with 95% confidence interval (95% CI). The risk of secondary cerebral ischemia and rebleeding was assessed as hazard ratio (HR) with 95% CI using Cox regression. Carriers of the subunit B His95Arg factor XIII polymorphism had an increased risk of aneurysmal SAH with 23% of the patients homozygous or heterozygous for the variant allele compared to 17% of control subjects (OR 1.5, 95% CI 1.0-2.2). For the remaining genetic variants no effect on the risk of aneurysmal SAH could be demonstrated. A clear relation with the risk of secondary cerebral ischemia and of rebleeding could not be established for any of the genetic variants. We found that aneurysmal SAH patients are more often carriers of the subunit B His95Arg factor XIII polymorphism compared to controls. This suggests that carriers of the subunit B His95Arg factor XIII polymorphism have an increased risk of aneurysmal SAH. Larger studies should confirm our results. As aneurysmal SAH patients who died soon after admission could not be included in the present study, our results only apply to a population of patients who survived the initial hours after the hemorrhage. For the other studied genetic factors involved in coagulation, no association with the occurrence of aneurysmal SAH or with the occurrence of secondary cerebral ischemia or rebleeding after aneurysmal SAH could be demonstrated
