The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Observation of psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi
No full textKolcu, Onur Buğra (Arel Author)Using 4.479 x 10(8) psi(3686) events collected with the BESIII detector, we search for the decays psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi, where J = 0, 1, 2. The decays psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi are observed for the first time. The measured branching fractions are B(psi(3686) -> e(+)e(-)chi(cJ)) = (11.7 +/- 2.5 +/- 1.0) x 10(-4), (8.6 +/- 0.3 +/- 0.6) x 10(-4), (6.9 +/- 0.5 +/- 0.6) x 10(-4) for J = 0, 1, 2, and B(chi(cJ) -> e(+)e(-)J/psi) = (1.51 +/- 0.30 +/- 0.13)x10(-4), (3.73 +/- 0.09 +/- 0.25)x10(-3), (2.48 +/- 0.08 +/- 0.16)x10(-3) for J = 0, 1, 2, respectively. The ratios of the branching fractions B(psi(3686) -> e(+)e(-)chi(cJ))/B(psi(3686) -> gamma chi(cJ)) and B(chi(cJ) -> e(+)e(-)J/psi)/B(chi(cJ) -> gamma J/psi) are also reported. Also, the alpha values of helicity angular distributions of the e(+)e(-) pair are determined for psi(3686) -> e(+)e(-)chi(c1,2) and chi(c1,2) -> e(+)e(-)J/psi
IN-CJ Development Model
No full textThe IN-CJ Development Model serves as a foundational framework for the International Network for Criminal Justice (IN-CJ), aimed at enhancing collaboration and knowledge sharing within the criminal justice field. This model, guided by values such as equality, peace, and respect, focuses on bridging the gaps between different criminal justice practices and perspectives across various countries.The development of a model that emphasises the significance of criminal justice as an international professional activity is of paramount importance in today’s interconnected world. The model acknowledges that criminal justice issues are not confined within national borders but are complex, transnational challenges that require a broad, global perspective. By fostering international collaboration and knowledge exchange, this development model helps criminal justice professionals from diverse jurisdictions to share best practices, innovative solutions, and varied experiences.This international approach also enriches the professional practice of criminal justice by exposing practitioners to a wide array of legal, social, and cultural contexts. It encourages them to think beyond their local environments and consider a wider range of strategies and methodologies, potentially leading to more effective and culturally sensitive justice solutions. Additionally, an international focus promotes the understanding of global crime trends, cross-border issues, and the impact of international policies, enabling practitioners to develop more comprehensive strategies to address crime and justice issues.Moreover, by valuing criminal justice as an international professional activity, this development model cultivates a diverse professional community. It bridges gaps between countries and disciplines, creating a network of professionals who are better equipped to tackle complex, global challenges collaboratively. This network not only enhances individual professional development but also contributes to the evolution of criminal justice as a field, making it more adaptable, inclusive, and effective in responding to the ever-changing landscape of international crime and justice.From fostering international partnerships to encouraging innovative approaches in policy development, the model provides a structured yet flexible approach to understanding and improving criminal justice systems globally. The model emphasises how community of practice principles and networks of practice approaches contribute to more effective and inclusive criminal justice practices. We hope that the IN-CJ Development Model will have significance in shaping a collaborative and informed approach to criminal justice worldwide.Key themes and issues include:Core Values: The model is centred around values of equality, peace, sustainability, respect, accountability, inclusivity, curiosity, and recognition. These values are integrated with various activities like knowledge exchange, experience exchange, ideas exchange, partnerships, collaboration, crowdsourcing, social value creation, individual and group agency, social capital, policy development, publishing, and learning and research.Aims and Purposes: The IN-CJ model aims to facilitate knowledge exchange, indirectly influence policy development, foster an inclusive and non-hierarchical environment, and provide an international perspective on criminal justice issues. It encourages exchanging knowledge and ideas between professions and countries, facilitates partnerships and collaborations, and explores crowdsourcing as a funding source. The model also focuses on publishing and learning to contribute to policy development and broaden criminal justice perspectives internationally.Network Development and Community of Practice: The model emphasises self-organizing networks and communities of practice (CoPs) to encourage collaboration, knowledge exchange, and innovation. It focuses on developing relationships within the network and leveraging them for collective learning and improvement.Networking Principles: The model incorporates principles like homophily, mutuality, transitivity, and decentralization. These principles shape the network’s configuration and enhance its effectiveness in knowledge exchange and concept development.Network Dynamics: The development of the network is influenced by collaborative choices, existing relationships, and a dynamic process that evolves, affecting the network’s structure and effectiveness.Network of Practice and CoPs: The model incorporates a network of practice for information exchange and perspectival empathy, enhancing learning, innovation, and collaboration. CoPs are used to promote cross-disciplinary dialogue, innovation, and knowledge sharing.Reflexive and Self-Evaluative Approach: The model adopts a reflexive and self-evaluative approach in developing the CoP, focusing on regular activities, conflict management, and continuous improvement.Broadening Perspectives and Policy Development: IN-CJ encourages broadening criminal justice perspectives and fostering better understanding among practitioners, policymakers, and researchers. It emphasises the importance of international perspectives, partnerships, collaboration, and policy development.Value Themes Matrix: The model uses a matrix to associate specific activities with the core values, providing clarity, guiding decision-making, and serving as a communication and evaluation tool.Specific Activities and Their Significance: Activities like knowledge exchange, experience exchange, ideas exchange, collaborative partnerships, crowdsourcing, social value creation, agency, and social capital are highlighted for their significance in enhancing the criminal justice system, fostering inclusivity, and influencing policy development.Overall, the IN-CJ Development Model is a start in the development of a comprehensive framework focusing on value-driven activities, international collaboration, and innovative practices to enhance the effectiveness and efficiency of criminal justice systems.</p
Asymptotic Stability of a Plane CJ Detonation Wave
No full text. We study the asymptotic stability of a plane CJ detonation wave under the assumption of small resolved heat release (SRHR). We prove that the solution exists globally and that the solution converges uniformly to a shifted CJ detonation wave as t!+ 1 for initial data which are small perturbations of the CJ detonation wave. The weighted energy method is used to overcome the difficulty arising from the sonic property at the end of the reaction. The SRHR model allows us to treat the non-monotone spike in the profile of the CJ detonation wave by the characteristic energy estimate. Key words. CJ detonation, shock wave, traveling wave, sonic point, asymptotic behavior, weighted energy estimate, characteristic energy estimate.

chi(cJ) polarizations at the Fermilab Tevatron
No full textWe propose the measurement of chi (cJ) polarizations at high energy hadron colliders to study heavy quarkonium production mechanism. We find that the color-singlet model in the k(t) factorization approach predicts very different behavior for chi (cJ) polarizations at the Fermilab Tevatron compared with the NRQCD predictions in the collinear parton model. In the color-singlet k(t) factorization approach, for both chi (c1) and chi (c2) productions, the helicity h = 0 states dominate over other helicity states at large p(T). These properties are very useful in distinguishing between the two production mechanisms which are related to the interesting issue of J psi and psi' polarizations, and may provide a crucial test for the k(t) factorization approach.

QCD radiative corrections to chi(cJ) production at hadron colliders
No full textTo clarify the outstanding problem in charmonium production that existing theories cannot explain the observed cross sections of chi(cJ)(J = 0, 1, 2) and ratio R-chi c = sigma(chi c2)/sigma(chi c1) approximate to 0.75(in contrast to the spin counting value 5/3) at the Tevatron, we study the complete next-to-leading order radiative corrections in nonrelativistic QCD, and find next-to-leading order contributions of P-3(J)vertical bar 1 vertical bar are more important than leading order at high p(T), and P-3(1)vertical bar 1 vertical bar decreases slower than P-3(2)vertical bar 1 vertical bar, implying a natural explanation for the R-chi c puzzle. By fitting R-chi c, the predicted cross sections of chi(cJ) are found to agree with data. The result indicates coloroctet contribution is crucially needed, thus providing a unique test for heavy quarkonium production mechanisms. Feed-down contributions of chi(cJ) to prompt J/psi production are estimated to be substantial, about 30%-40% at p(T) = 20 GeV. Production of chi(cJ)(J = 0, 1, 2) at the LHC is also predicted.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000291464100001&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Astronomy & AstrophysicsPhysics, Particles & FieldsSCI(E)71ARTICLE11null8
