The economic impact of consumer copyright exceptions: a literature review

Advances in the technology available to consumers have fundamentally altered the relationship between authors, rights-holders and consumers with regard to copyrighted creative works. The copyright system in the UK is undergoing a gradual process of reform to reflect this new reality. In 2006, Andrew Gowers, a former editor of the Financial Times, presented a report into the state of intellectual property in the U.K. Among his policy recommendations were three proposed changes to the copyright exceptions system which alter the way in which consumers can interact with copyrighted works. Gowers proposed introducing copyright exceptions for: - Format shifting, for instance the transfer of a piece of music from a CD to an mp3 player. - Parody, caricature and pastiche. - Creative, transformative or derivative works. In our context, this definition includes user-generated content. Our review examines the existing literature on the possible economic effects of these proposed changes to the copyright exceptions system, specifically whether the introduction of these proposed changes would cause economic damage to rights-holders. Whilst the economic issues surrounding copyright infringement via file-sharing and commercial "mash-ups" are interesting and important, our review is focused solely on copyright

Hunting for neutral, long-lived exotica at the LHC using a missing transverse energy signature

Searches at the Large Hadron Collider (LHC) for neutral, long-lived particles have historically relied on the detection of displaced particles produced by their decay $\textit{within}$ the detector volume. In this paper we study the potential of the complementary signature comprising of the missing transverse energy ($E_T^{miss}$) signal, traditionally used to look for dark matter, e.g., the lightest supersymmetric particle (LSP), to extend the LHC coverage to models with long-lived (LL) particles when they decay $\textit{outside}$ the detector. Using CMS and ATLAS analyses at the 8 TeV LHC, we set an upper limit at the 95% confidence level (CL) on the production cross sections for two specific scenarios: (i) a model with a heavy non-standard model Higgs boson decaying to a LL scalar and (ii) an R-parity violating RPV SUSY model with a LL neutralino. We show that this method can significantly extend the LHC sensitivity to neutral, LL particles with arbitrary large lifetimes and that the limits obtained from a $E_T^{miss}$ signal are comparable to those from displaced particle searches for decay distances above a few meters. Results obtained in this study do not not depend on the specific decay channel of the LL particle and therefore are model-independent in this sense. We provide limits for the whole two-dimensional plane in terms of the mass of the LL particle and the mass of the mediator up to masses of 2 TeV including particular benchmarks studied in the original experimental papers. We have made these limits available in the form of a grid which can be used for the interpretation of various other new physics models.Comment: 28 page

Gender and the Greening of Buddhism: Exploring Scope for a Buddhist Ecofeminism in an Ultramodern Age

Despite its popularity and appeal for many, ecofeminism has been criticized for essentializing and romanticizing women’s roles as close to nature, thereby reproducing colonialist and biologically determinist discourses that contribute to discrimination. In response there have been attempts to defend ecofeminism, arguing that such critiques are hyperbolic and that we need ecofeminism more than ever (Philips and Rumens 2016). In a climate of renewed interest in ecofeminism, I ask why is it that some faith traditions are represented to a far greater extent in ecofeminist literature than others? I pick up on this discrepancy within ecofeminism’s engagement between different religions through examining Buddhist responses to gender and ecology. In the article I adopt a theory of ultramodern Buddhism, developed by Halafoff and Rajkobal (2015), to understand Buddhism in the contemporary era. Three main research questions are addressed: (1) to what extent has ‘green Buddhism’ been gendered?; (2) why has there has been virtually no attempt to bring together feminist analysis with responses to Buddhism and environmentalism? Why have they been approached separately?; and (3) in what ways are Buddhist women (and men) combining gender analysis and environmentalism in practice in reference to or outside the framework of ecofeminism? To better understand why a Buddhist ecofeminism has not been named and claimed by Buddhists in either the West or Asia, there is a need for local-level empirical studies that examine subjective understandings of relationships between gender and environmentalism in the lives of ultramodern Buddhist practitioners rather than assuming a standard ecofeminist position as the primary reference point

b Tagging in CMS

Many of the exotic particles expected at the LHC, such as SUSY, Higgs bosons and top quarks, will decay to b quarks. This paper presents the methods used to identify b-jets at CMS. The algorithms exploit the long B hadron lifetime, semi-leptonic B decays and jet kinematics. The prospect for measuring the performance of these b-tags directly from CMS data is examined. Finally, the use of b-tagging in the High-Level Trigger is explained

Aspects of planning in relation to Claremont shopping centre

The activity with which this thesis is concerned is that of retailing; the area of focus being the shopping centre. This environment is one which displays a complex set of spatial and human relationships involving amongst others location, size, rent structure, shopping mix, movement, fashion, socio-economic status, expenditure patterns and consumer behaviour. It can be demonstrated that if certain of these factors are left to respond to what is generally known as the "market mechanism", the resultant environment usually exhibits certain undesirable features such as congestion, pollution and commercial blight. The planner seeks, amongst other aims to create an environment which is optimal and balanced and which provides for human needs such as convenience and safety

Migrations of spiny rock-lobsters, Jasus Lalandii, at Luderitz : environmental causes, and effects on the fishery and benthic ecology

Includes bibliographical references.A dispute arose in the Luderitz rock-lobster, Jasus lalandii, fishery as to whether declines in CPUE were due to changes in rock-lobster migration patterns or a reduction in fishable biomass. Rock-lobster migrations were studied at two sites by estimating in situ density in the 10-12m and 15-20m depth zones. Water temperature and dissolved oxygen concentration profiles were obtained at several sites at approximately monthly intervals. Observations over a period of six years indicated that rock-lobster underwent seasonal in- offshore migrations and that marked interannual variation in those migration patterns did, indeed, occur. The movements and their interannual variation were directly related to the inshore presence of water with very low dissolved oxygen concentrations. CPUE was closely related to the density of legal sized rock-lobster on the fishing grounds (observed by SCUBA diving) and hence it is feasible that at least a part of the decline in CPUE at Luderitz was due to an alteration in the "normal" pattern of in-offshore migration. The hypothesis that environmental change caused the major decline in rock-lobster catches at Luderitz was examined by time series analysis of 21 years of CPUE, wind, SST and sea-level data. Luderitz rocklobster CPUE was found to be negatively correlated with the southerly component of summer wind stress at Diaz Point six years previously. On this basis it was hypothesised that variable settlement of puerulus larvae is an important factor driving changes in recruitment to the fishable population. The mechanism may be increased mortality of larvae as they attempt to cross the continental shelf (due to greater northward and offshore drift during periods of strong southerly wind). The dramatic interannual changes in rock-lobster density provided an opportunity to carry out a "natural" experiment on the interaction between rock-lobsters and the associated benthic species assemblage. It was found that, although there were changes in the benthos (notably an increase and subsequent decline in whelk density), these were unrelated to variation in rock-lobster density. In addition, no relationship between per capita food availability and rock-lobster growth on four grounds, was apparent. As regards temporal changes in food supply and subsequent effects on rock-lobster growth rates; there was no temporal reduction in food supply at the main study site which could be related to the reduction in CPUE since 1988

Quarantining online hate speech: technical and ethical perspectives

Abstract: In this paper we explore quarantining as a more ethical method for delimiting the spread of Hate Speech via online social media platforms. Currently, companies like Facebook, Twitter, and Google generally respond reactively to such material: offensive messages that have already been posted are reviewed by human moderators if complaints from users are received. The offensive posts are only subsequently removed if the complaints are upheld; therefore, they still cause the recipients psychological harm. In addition, this approach has frequently been criticised for delimiting freedom of expression, since it requires the service providers to elaborate and implement censorship regimes. In the last few years, an emerging generation of automatic Hate Speech detection systems has started to offer new strategies for dealing with this particular kind of offensive online material. Anticipating the future efficacy of such systems, the present article advocates an approach to online Hate Speech detection that is analogous to the quarantining of malicious computer software. If a given post is automatically classified as being harmful in a reliable manner, then it can be temporarily quarantined, and the direct recipients can receive an alert, which protects them from the harmful content in the first instance. The quarantining framework is an example of more ethical online safety technology that can be extended to the handling of Hate Speech. Crucially, it provides flexible options for obtaining a more justifiable balance between freedom of expression and appropriate censorship

Measuring perceived empathy in dialogue systems

Dialogue systems, from Virtual Personal Assistants such as Siri, Cortana, and Alexa to state-of-the-art systems such as BlenderBot3 and ChatGPT, are already widely available, used in a variety of applications, and are increasingly part of many people’s lives. However, the task of enabling them to use empathetic language more convincingly is still an emerging research topic. Such systems generally make use of complex neural networks to learn the patterns of typical human language use, and the interactions in which the systems participate are usually mediated either via interactive text-based or speech-based interfaces. In human–human interaction, empathy has been shown to promote prosocial behaviour and improve interaction. In the context of dialogue systems, to advance the understanding of how perceptions of empathy affect interactions, it is necessary to bring greater clarity to how empathy is measured and assessed. Assessing the way dialogue systems create perceptions of empathy brings together a range of technological, psychological, and ethical considerations that merit greater scrutiny than they have received so far. However, there is currently no widely accepted evaluation method for determining the degree of empathy that any given system possesses (or, at least, appears to possess). Currently, different research teams use a variety of automated metrics, alongside different forms of subjective human assessment such as questionnaires, self-assessment measures and narrative engagement scales. This diversity of evaluation practice means that, given two DSs, it is usually impossible to determine which of them conveys the greater degree of empathy in its dialogic exchanges with human users. Acknowledging this problem, the present article provides an overview of how empathy is measured in human–human interactions and considers some of the ways it is currently measured in human–DS interactions. Finally, it introduces a novel third-person analytical framework, called the Empathy Scale for Human–Computer Communication (ESHCC), to support greater uniformity in how perceived empathy is measured during interactions with state-of-the-art DSs

"And he knew our language"

This ambitious and ground-breaking book examines the linguistic studies produced by missionaries based on the Pacific Northwest Coast of North America (and particularly Haida Gwaii) during the late nineteenth and early twentieth centuries. Making extensive use of unpublished archival materials, the author demonstrates that the missionaries were responsible for introducing many innovative and insightful grammatical analyses. Rather than merely adopting Graeco-Roman models, they drew extensively upon studies of non-European languages, and a careful exploration of their scripture translations reveal the origins of the Haida sociolect that emerged as a result of the missionary activity. The complex interactions between the missionaries and anthropologists are also discussed, and it is shown that the former sometimes anticipated linguistic analyses that are now incorrectly attributed to the latter
