Commentary on An Enquiry into the Nature and Origin of Literary Property (1762)

One of a number of published commentaries contributing to the mid-eighteenth century debate concerning the nature of literary property. The author of An Enquiry sought to repudiate the concept of a natural authorial property right existing at common law. In so doing, he specifically engaged with various aspects of William Warburton's earlier commentary (see: uk_1747), as well as presenting arguments that drew upon the nature of property in general, the differences between the right claimed by proponents of the common law right and other acknowledged incorporeal properties, the similarities between patents and copyright, the history of literary property, the experience of other jurisdictions (drawing upon Venice in particular), and the consequences that would follow from conceding the existence of a perpetual right both for authors in particular and society in general. This commentary, in turn, drew its own response in the guise of A Vindication of the Exclusive Rights of Authors, to their own work (1762).

Noise resilient discrete-time cross-relation sensor characterisation

In-situ characterisation of thermocouple sensors is a challenging problem. Recently the authors presented a blind characterisation technique based on the cross-relation method of blind identification. The method allows in-situ identification of two thermocouple probes, each with a different dynamic response, using only sampled sensor measurement data. While the technique offers certain advantages over alternative methods, including low estimation variance and the ability to compensate for noise induced bias, the robustness of the method is limited by the multimodal nature of the cost function. In this paper, a normalisation term is proposed which improves the convexity of
the cost function. Further, a normalisation and bias compensation hybrid approach is presented that exploits the advantages of both normalisation and bias compensation. It is found that the optimum of the hybrid cost function is less biased and more stable than when only normalisation is applied. All results were verified by simulation.

Soil-less systems vs. soil-based systems for cultivating edible plants on buildings in relation to the contribution towards sustainable cities

Food production and consumption for cities has become a global concern due to increasing numbers of people living in urban areas, threatening food security. There is the contention that people living in cities have become disconnected with food production, leading to reduced nutrition in diets and increased food waste. Integrating food production into cities (urban agriculture) can help alleviate some of these issues. Lack of space at ground level in high-density urban areas has accelerated the idea of using spare building surfaces for food production. There are various growing methods being used for food production on buildings, which can be split into two main types, soil-less systems and soil-based systems. This paper is a holistic assessment (underpinned by the triple bottom line of sustainable development) of these two types of systems for food production on buildings, looking at the benefits and limitation of each type in this context. The results illustrate that soil-less systems are more productive per square metre, which increases the amount of locally grown, fresh produce available in urban areas. The results also show that soil-based systems for cultivation on buildings are more environmentally and socially beneficial overall for urban areas than soil-less systems.

Étude du livre de Daniel Lerner "The passing of traditional society: modernizing the Middle East" et de sa réception par la communauté scientifique

Cette étude a pour but de mettre en contexte la thèse de la modernisation psychique de Daniel Lerner, de faire une analyse interne de l’ouvrage et d’étudier sa réception par les sociologues de l’époque. Comme démarche de recherche, dans un premier temps, nous replacerons l’ouvrage dans la situation historique des deux premières décennies de la guerre froide (les années 50 et 60). Ce faisant, nous tenterons de comprendre la logique de la politique de développement des États-Unis à l’endroit des pays en voie de développement et la place des recherches universitaires dans la politique coloniale américaine. L’approche du développement exogène a largement inspiré les politiques étrangères des pays occidentaux et leurs efforts pour lancer le développement des pays plus nécessiteux. C’est pour cela que Lerner se concentre sur l’effet des médias américains, et surtout du Voice of America, pour analyser le rôle que ceux-ci jouent dans le processus de transformation de la personnalité. Pour aborder cette étape de la recherche, nous devrons comprendre davantage le contexte de l’ouvrage et mieux analyser la relation entre les facteurs externes et les éléments internes qui ont influencé la formation de l’ouvrage. Dans un deuxième temps, nous étudierons l’ouvrage de Lerner et nous discuterons des différents aspects relatifs aux changements sociaux que l’ouvrage a examinés. Dans notre analyse de l’ouvrage, nous critiquerons divers aspects de la pensée sociologique de Lerner et sa manière d’interpréter les faits sociaux et les statistiques. Dans un troisième temps, nous réviserons la réception de l’ouvrage par la communauté scientifique de son époque pour obtenir une large vision de la place de l’oeuvre dans l’histoire de la pensée sociologique américaine du développement. Nous établirons une catégorisation des recensions de l’ouvrage portant sur l’approche sociologique de Lerner et nous mettrons ces recensions dans l’éclairage des champs de recherches universitaires américaines. Nous nous concentrerons sur la réception de cette théorie chez les sociologues de l’époque pour comprendre la dialectique entre la thèse qui y est défendue et la société. Ce faisant, nous éviterons de nous éloigner de la sociologie comme étant la discipline de l’étude des liens sociaux et des interactions symboliques et nous éviterons de réduire notre démarche sociologique à une simple étude historique des idées. En gros, nous discuterons de la vision sociologique de l’auteur, de la façon dont son ouvrage a été formé au fil du temps et comment il a été influencé par l’esprit de son époque. De plus, nous verrons comment l’écrivain s’est nourri des théories sociologiques et à quel point il a influencé la pensée sociologique de son temps. Tout cela, en parallèle à l’analyse interne de l’ouvrage, nous permettra de saisir la place de «The Passing of Traditional Society» dans la pensée sociologique américaine. Cette recherche nous aidera à mieux comprendre la vision américaine de l’empathie en tant qu’un élément modernisateur, par rapport à la question du développement dans le contexte historique de l’époque. Cette compréhension nous mènera à approfondir notre analyse des programmes de développement des États-Unis dans le monde en voie du développement. Cette étude nous amènera aussi à élargir notre vision quant aux idées construites et formées dans leur contexte historique (en général) et à découvrir comment la communauté scientifique reste toujours en parti prisonnière de son contexte historique. Cette étude nous permettra de mieux voir les idées (le texte) en relation avec la société, ce qui est vital pour ne pas tomber dans la réduction des idées seulement au texte ou seulement au contexte. En outre, elle nous aidera à comprendre davantage la façon dont la société intervient dans la formation des idées et comment en retour les idées influencent la société.

Nature-based solutions to climate change mitigation and adaptation in urban areas: perspectives on indicators, knowledge gaps, barriers, and opportunities for action

Nature-based solutions promoting green and blue urban areas have significant potential to decrease the vulnerability and enhance the resilience of cities in light of climatic change. They can thereby help to mitigate climate change-induced impacts and serve as proactive adaptation options for municipalities. We explore the various contexts in which nature-based solutions are relevant for climate mitigation and adaptation in urban areas, identify indicators for assessing the effectiveness of nature-based solutions and related knowledge gaps. In addition, we explore existing barriers and potential opportunities for increasing the scale and effectiveness of nature-based solution implementation. The results were derived from an inter- and transdisciplinary workshop with experts from research, municipalities, policy, and society. As an outcome of the workshop discussions and building on existing evidence, we highlight three main needs for future science and policy agendas when dealing with nature-based solutions: (i) produce stronger evidence on nature-based solutions for climate change adaptation and mitigation and raise awareness by increasing implementation; (ii) adapt for governance challenges in implementing nature-based solutions by using reflexive approaches, which implies bringing together new networks of society, nature-based solution ambassadors, and practitioners; (iii) consider socio-environmental justice and social cohesion when implementing nature-based solutions by using integrated governance approaches that take into account an integrative and transdisciplinary participation of diverse actors. Taking these needs into account, nature-based solutions can serve as climate mitigation and adaptation tools that produce additional cobenefits for societal well-being, thereby serving as strong investment options for sustainable urban planning.

SMART social science? Examining the nature and role of social scientific expertise in institutional design

Daniel Bromley argues against Oran Young’s FIT model as a basis for environmental governance, on the grounds that humans cannot manage nature and that attempts to do so are based on a scientistic, modernist conceit. At issue is the role of natural and social scientists in adjudicating questions about what we ought to do to close governance gaps and address unsustainable behaviors. If Bromley is right, then the lessons of the American pragmatist tradition recommend against attempts to “fit” social institutions to the natural world. The first objective of this paper is to argue that Bromley’s view is not in keeping with the pragmatism of C. S. Peirce and John Dewey, which actually places a high value on natural and social scientific modes of inquiry in the service of social ends. I argue that Young’s proposal is in fact a development of the pragmatist idea that social institutions must be fit in the sense of fitness, i.e., resilient and able to navigate uncertainty. Social institutions must also evolve to accommodate the emerging values of the agents who operate within them. The second objective of this paper is to examine the role of social science expertise in the design of social policies. Governance institutions typically rely on the testimony of natural scientists, at least in part, to understand the natural systems they operate within. However, natural systems are also social systems, so it seems pertinent to ask whether there is a role for social systems experts to play in helping to design environmental governance institutions. I argue that social scientists can make a unique contribution as experts on social institutions, and as such, are necessary to bring about a transformation of the unsustainable institutions that are preventing us from achieving stated sustainable development goals.

Undertaking Sensitive Interviews: Reflections on Interviewing Bereaved Parents

Paediatric palliative care is a rare experience for many GPs. Although they recognise that they have a role to play, and can be is value in providing palliative care, their ability to fulfil this role can be hindered by a lack of role clarity. A qualitative study set in the West Midlands, examined the role of the GP in children's oncology palliative care from the perspective of the GP who had cared for the child receiving palliative scare for cancer at home and the bereaved parent. One-to-one semi-sturcured interviews were undertaken with 18 GPs an 11 bereaved parent following the death. A ground theory data analysis was undertaken: identifying generated themes through chronological comparative data analysis. Reflecting on my experiences working with bereaved families both as a paediatric Macmillan nurse and a researcher, the challenges of undertaking sensitive research, in relation to the vulnerability of the particular group and the nature of questions being asked will be explored.

A guideline to improve qualitative social science publishing in ecology and conservation journals

A rise in qualitative social science manuscripts published in ecology and conservation journals speaks to the growing awareness of the importance of the human dimension in maintaining and improving Earth’s ecosystems. Given the rise in the quantity of qualitative social science research published in ecology and conservation journals, it is worthwhile quantifying the extent to which this research is meeting established criteria for research design, conduct, and interpretation. Through a comprehensive review of this literature, we aimed to gather and assess data on the nature and extent of information presented on research design published qualitative research articles, which could be used to judge research quality. Our review was based on 146 studies from across nine ecology and conservation journals. We reviewed and summarized elements of quality that could be used by reviewers and readers to evaluate qualitative research (dependability, credibility, confirmability, and transferability); assessed the prevalence of these elements in research published in ecology and conservation journals; and explored the implications of sound qualitative research reporting for applying research findings. We found that dependability and credibility were reasonably well reported, albeit poorly evolved in relation to critical aspects of qualitative social science such as methodology and triangulation, including reflexivity. Confirmability was, on average, inadequately accounted for, particularly with respect to researchers’ ontology, epistemology, or philosophical perspective and their choice of methodology. Transferability was often poorly developed in terms of triangulation methods and the suitability of the sample for answering the research question/s. Based on these findings, we provide a guideline that may be used to evaluate qualitative research presented in ecology and conservation journals to help secure the role of qualitative research and its application to decision making.

How game changers catalyzed, disrupted, and incentivized social innovation: three historical cases of nature conservation, assimilation, and women’s rights

We explore the impact of “game changers” on the dynamics of innovation over time in three problem domains, that of wilderness protection, women’s rights, and assimilation of indigenous children in Canada. Taking a specifically historical and cross-scale approach, we look at one social innovation in each problem domain. We explore the origins and history of the development of the National Parks in the USA, the legalization of contraception in the USA and Canada, and the residential school system in Canada. Based on a comparison of these cases, we identify three kinds of game changers, those that catalyze social innovation, which we define as “seminal,” those that disrupt the continuity of social innovation, which we label exogenous shocks, and those that provide opportunities for novel combinations and recombinations, which we label as endogamous game changers.

La invocación de los antepasados en "De divinatione" y "De natura deorum" de Cicerón. "Religio e identidad" romana a fines de la república

La invocación del ideal del mos maiorum, entendido como conjunto de virtudes o rasgos ejemplares de los romanos, ha sido estudiada repetidamente en los textos de Cicerón. Analiza el tópico en relación con la discusión en torno a la identidad romana en textos del siglo I a.C. y delimita tres empleos diferentes: uno al que define como típicamente aristocrático, referido a la ascendencia noble de un individuo en particular; un segundo uso que, en vez de individualizar, amalgama a todos los ancestros en un mismo conjunto y establece una continuidad entre pasado y presente; finalmente, una tercera modalidad que propone una ruptura total entre el mundo de los antepasados y el de los contemporáneos. En este trabajo indagaremos el funcionamiento de este tópico en De diuinatione y De natura deorum de Cicerón. Desde nuestro punto de vista, el ideal del mos maiorum no solamente involucra virtudes éticas y morales sino que también supone una especial actitud con respecto a los dioses y el culto que resulta central en la definición de la identidad romana.

Development of a model to predict the life of pneumatic conveyor bends subject to erosive wear

The erosion processes resulting from flow of fluids (gas-solid or liquid-solid) are encountered in nature and many industrial processes. The common feature of these erosion processes is the interaction of the fluid (particle) with its boundary thus resulting in the loss of material from the surface. This type of erosion in detrimental to the equipment used in pneumatic conveying systems. The puncture of pneumatic conveyor bends in industry causes several problems. Some of which are: (1) Escape of the conveyed product causing health and dust hazard; (2) Repairing and cleaning up after punctures necessitates shutting down conveyors, which will affect the operation of the plant, thus reducing profitability. The most common occurrence of process failure in pneumatic conveying systems is when pipe sections at the bends wear away and puncture. The reason for this is particles of varying speed, shape, size and material properties strike the bend wall with greater intensity than in straight sections of the pipe. Currently available models for predicting the lifetime of bends are inaccurate (over predict by 80%. The provision of an accurate predictive method would lead to improvements in the structure of the planned maintenance programmes of processes, thus reducing unplanned shutdowns and ultimately the downtime costs associated with these unplanned shutdowns. This is the main motivation behind the current research. The paper reports on two aspects of the first phases of the study-undertaken for the current project. These are (1) Development and implementation; and (2) Testing of the modelling environment. The model framework encompasses Computational Fluid Dynamics (CFD) related engineering tools, based on Eulerian (gas) and Lagrangian (particle) approaches to represent the two distinct conveyed phases, to predict the lifetime of conveyor bends. The method attempts to account for the effect of erosion on the pipe wall via particle impacts, taking into account the angle of attack, impact velocity, shape/size and material properties of the wall and conveyed material, within a CFD framework. Only a handful of researchers use CFD as the basis of predicting the particle motion, see for example [1-4] . It is hoped that this would lead to more realistic predictions of the wear profile. Results, for two, three-dimensional test cases using the commercially available CFD PHOENICS are presented. These are reported in relation to the impact intensity and sensitivity to the inlet particle distributions.

Quantitative characterization of physico-chemical properties of the active layers of reverse osmosis and nanofiltration membranes, and their relation to membrane performance

The main objectives of this dissertation were: (i) to develop experimental and analytical procedures to quantify different physico-chemical properties of the ultra-thin (~ 100 nm) active layers of reverse osmosis (RO) and nanofiltration (NF) membranes and their interactions with contaminants; (ii) to use such procedures to evaluate the similarities and differences between the active layers of different RO/NF membranes; and (iii) to relate characterization results to membrane performance. Such objectives were motivated by the current limited understanding of the physico-chemical properties of active layers as a result of traditional characterization techniques having limitations associated with the nanometer-scale spatial resolution required to study these ultra-thin films. Functional groups were chosen as the main active layer property of interest. Specific accomplishments of this study include the development of procedures to quantify in active layers as a function of pH: (1) the concentration of both negatively and positively ionized functional groups; (2) the stoichiometry of association between ions (i.e., barium) and ionized functional groups (i.e., carboxylate and sulfonate); and (3) the steric effects experienced by ions (i.e., barium). Conceptual and mathematical models were developed to describe experimental results. The depth heterogeneity of the active layer physico-chemical properties and interactions with contaminants studied in this dissertation was also characterized. Additionally, measured concentrations of ionized functional groups in the polyamide active layers of several commercial RO/NF membranes were used as input in a simplified RO/NF transport model to predict the rejection of a strong electrolyte (i.e., potassium iodide) and a weak acid (i.e., arsenious acid) at different pH values based on rejection results at one pH condition. The good agreement between predicted and experimental results showed that the characterization procedures developed in this study serve as useful tools in the advancement of the understanding of the properties and structure of the active layers of RO/NF membranes, and the mechanisms of contaminant transport through them.

Graphic satire and the rise and fall of the First British Empire: political prints from the Seven Years' War to the Treaty of Paris, c. 1756-1783

This thesis examines the early stages of the transformation of emblematic political prints into political caricature from the beginning of the Seven Years' War (1756) to the Treaty of Paris, which ended the American Revolutionary War (1783). Both contextual and iconographical issues are investigated in relation to the debates occasioned by Britain's imperial project, which marked a period of dramatic expansion during the Seven Years' War, and ended with the loss of the American colonies, consequently framing this thesis as a study of political prints during the rise and fall of the so-called 'First British Empire'. Previous studies of eighteenth-century political prints have largely ignored the complex and lengthy evolutionary process by which the emblematic mode amalgamated with caricatural representation, and have consequently concluded that political prints excluded emblems entirely by the end of the 1770s. However, this study emphasizes the significance of the Wilkite movement for the promotion and preservation of emblems, and investigates how pictorial political argument was perceived and received in eighteenth-century British society, arguing that wider tastes and opinions regarding the utilization of political prints gradually shifted to accept both modes of representation. Moreover, the marketplace, legal status, topicality, and manufacturing methods of political prints are analyzed in terms of understanding the precarious nature of their consumption and those that endeavoured to engage in political printmaking. The evolution, establishment, and subsequent appropriation of pictorial tropes is discussed from the early modern period to the beginning of the so-called Golden Age of caricature, while tracing the adaptation of representational models in American colonial prints that employed emblems already entrenched in British pictorial political debate. Political prints from the two largest print collections, the British Museum and the Lewis Walpole Library at Yale are consulted, along with a number of eighteenth-century newspapers and periodicals, to develop the earlier research by M. Dorothy George, Charles Press, Herbert Atherton, Diana Donald, Amelia Rauser, and Eirwen Nicholson.
