description: The OPERA neutrino oscillation experiment foresees the construction of two magnetized iron spectrometers located after the lead-nuclear emulsion targets. The magnet is made up of two vertical walls of rectangular cross section connected by return yokes. The particle trajectories are measured by high precision drift tubes located before and after the arms of the magnet. Moreover, the magnet steel is instrumented with Resistive Plate Chambers that ease pattern recognition and allow a calorimetric measurement of the hadronic showers. In this paper we review the construction of the spectrometers. In particular, we describe the results obtained from the magnet and RPC prototypes and the installation of the final apparatus at the Gran Sasso laboratories. We discuss the mechanical and magnetic properties of the steel and the techniques employed to calibrate the field in the bulk of the magnet. Moreover, results of the tests and issues concerning the mass production of the Resistive Plate Chambers are reported. Finally, the expected physics performance of the detector is described; estimates rely on numerical simulations and the outcome of the tests described above.

description: We apply the spectral energy distribution (SED) fitting code ProSpect to multiwavelength imaging for $\sim$7,000 galaxies from the GAMA survey at $z<0.06$, in order to extract their star formation histories. We combine a parametric description of the star formation history with a closed-box evolution of metallicity where the present-day gas-phase metallicity of the galaxy is a free parameter. We show with this approach that we are able to recover the observationally determined cosmic star formation history (CSFH), an indication that stars are being formed in the correct epoch of the Universe, on average, for the manner in which we are conducting SED fitting. We also show the contribution to the CSFH of galaxies of different present-day visual morphologies, and stellar masses. Our analysis suggests that half of the mass in present-day elliptical galaxies was in place 11 Gyr ago. In other morphological types, the stellar mass formed later, up to 6 Gyr ago for present-day irregular galaxies. Similarly, the most massive galaxies in our sample were shown to have formed half their stellar mass by 11 Gyr ago, whereas the least massive galaxies reached this stage as late as 4 Gyr ago (the well-known effect of "galaxy downsizing"). Finally, our metallicity approach allows us to follow the average evolution in gas-phase metallicity for populations of galaxies, and extract the evolution of the cosmic metal mass density in stars and in gas, producing results in broad agreement with independent, higher-redshift observations of metal densities in the Universe.

description: The aim of this systematic review was to synthesise the research identifying possible influences on CBT outcomes in chronic pain. Variations in the effectiveness of psychological therapies, such as CBT, in chronic pain have led to research investigating predictors of improved treatment outcomes. We identified randomised controlled and cohort studies of CBT for chronic pain, published between 1974 to 2nd August 2023, which identified predictors of CBT outcomes. Nineteen studies were included in the review. Baseline sociodemographic, physical and emotional factors that influence the outcomes of CBT for chronic pain were identified. The most commonly reported predictors of CBT outcome, with medium to large effect sizes, were anxiety, depression and negative cognitions about pain and coping. Sociodemographic predictors of outcomes demonstrated small effects and lacked replicability. There was variability across study designs, CBT delivery and outcomes measures. Further research is needed in chronic pain to identify the predictive factors which influence treatment outcomes, and consistency across study designs and outcome variables is needed to reduce heterogeneity. This review synthesised research identifying factors predicting outcomes of Cognitive Behavioural Therapy for chronic pain.The most commonly reported predictors of Cognitive Behavioural Therapy outcome, with medium to large effect sizes, were anxiety, depression, and negative cognitions about pain and coping. sociodemographic predictors of outcomes demonstrated small effects and lacked replicability.There is a move towards more individualised treatments in chronic pain.Our results suggest that decisions regarding Cognitive Behavioural Therapy for chronic pain should carefully consider baseline levels of anxiety, depression, and negative cognitions about pain.

description: AGN-driven outflows are believed to play an important role in regulating the growth of galaxies mostly via negative feedback. However, their effects on their hosts are far from clear, especially for low and moderate luminosity Seyferts. To investigate this issue, we have obtained cold molecular gas observations, traced by the CO(2-1) transition, using the NOEMA interferometer of five nearby (distances between 19 and 58 Mpc) Seyfert galaxies. The resolution of approx. 0.3-0.8 arcsec (approx. 30-100 pc) and field of view of NOEMA allowed us to study the CO(2-1) morphology and kinematics in the nuclear regions (approx. 100 pc) and up to radial distances of approx. 900 pc. We have detected CO(2-1) emission in all five galaxies with disky or circumnuclear ring like morphologies. We derived cold molecular gas masses on nuclear (approx. 100 pc) and circumnuclear (approx. 650 pc) scales in the range from $10^6$ to $10^7$M$_{\odot}$ and from $10^7$ to $10^8$ $M_{\odot}$, respectively. In all of our galaxies the bulk of this gas is rotating in the plane of the galaxy. However, non-circular motions are also present. In NGC 4253, NGC 4388 and NGC 7465, we can ascribe the streaming motions to the presence of a large-scale bar. In Mrk 1066 and NGC 4388, the non-circular motions in the nuclear regions are explained as outflowing material due to the interaction of the AGN wind with molecular gas in the galaxy disk. We conclude that for an unambiguous and precise interpretation of the kinematics of the cold molecular gas we need a detailed knowledge of the host galaxy (i.e., presence of bars, interactions, etc) as well as of the ionized gas kinematics and the ionization cone geometry.

Triple-X and beyond: hadronic systems of three and more X(3872)

description: The $X(3872)$ resonance has been conjectured to be a $J^{PC} = 1^{++}$ charm meson-antimeson two-body molecule. Meanwhile, there is no experimental evidence for larger, few-body compounds of multiple charm meson-antimeson pairs which would resemble larger molecules or nuclei. Here, we investigate such multi-meson states to the extent of what can be deduced theoretically from essentials of the interaction between uncharged $D^{0}$ and $D^{*0}$ mesons. From a molecular $X(3872)$, we predict a $4X$ ($4^{++}$) octamer with a binding energy \mbox{$B_{4X} > 2.08\,{\rm MeV}$,} assuming a $D^{*0} \bar{D}^0$ system close to the unitary limit (as suggested by the mass of the $X(3872)$). If we consider heavy-quark spin symmetry explicitly, the $D^{*0} \bar{D}^{*0}$ ($2^{++}$) system is close to unitarity, too. In this case, we predict a bound $3X$ ($3^{++}$) hexamer with $B_{3X} > 2.29\,{\rm MeV}$ and a more deeply bound $4X$ octamer with $B_{4X} > 11.21\,{\rm MeV}$. These results exemplify with hadronic molecules a more general phenomenon of equal-mass two-species Bose systems comprised of equal number of either type: the emergence of unbound four- and six-boson clusters in the limit of a short-range two-body interaction which acts only between bosons of different species. Finally, we also study the conditions under which a $2X$ ($2^{++}$) tetramer might form.

description: The international debate on international monetary reform that began in the early 1960s ha proceeded with a logic and consistency unparalleled in other areas of international relations. The SDR agreement, in particular, constitutes a major breakthrough, deemed until recently to be totally utopian and unattainable, toward a rational management of the international monetary system. The agreement as it now stands, however, still fails to deal adequately with the objective of an allocation of SDRs serving collectively agreed purposes rather than unilaterally decided national policies, potentially disruptive of equilibrium and/or obnoxious to the countries called upon to finance them through forcible SDR accumulation. The author argues that internationally created reserves should be used for internationally agreed upon objectives, rather than the blind financing of national policies that may be financially, economically or politically disruptive.

Bodies of evidence : human decapitation during the early intermediate period in the Acarí Valley, south coast, Peru
Creators: name: Smith, Craig Preston

description: The Nasca, who occupied parts of the Peruvian south coast during the Early Intermediate Period (EIP; ca. A.D. 1-750), are famous for their immense ground drawings, elaborate textiles, and attractive polychrome pottery. They are also well-known for their practice of collecting and modifying human heads. Caches of these well-preserved, and often mummified, "trophy" heads have been found by archaeologists working in the valleys of the Rio Grande de Nazca drainage, once the heartland of Nasca society. Based on the contexts in which they are found, as well as their depiction in the iconography of the Nasca and earlier Paracas culture (ca. 800 B.C. - A.D. 1), the heads have come to be seen as important ideological symbols, which were likely incorporated in rituals centered on themes of water, fertility, and regeneration. While the interpretation of the ritual purpose of Nasca "trophy" heads is widely accepted, the nature and context in which the heads were obtained is the subject of much debate. Until recently, however, there has been a dearth of skeletal evidence with which to test the competing hypotheses about the source of Nasca trophy heads. During the 2005 and 2006 field seasons of the Acari Valley Archaeological Project, investigators found the remains of 54 decapitated individuals at the site of Amato, just 80 km south of the Nasca ceremonial center of Cahuachi. Demographic analysis of the skeletons revealed that both sexes and all age groups are represented. Not only does this discovery represent the largest-known association of its kind in the south coast, but the presence of such a large sampling of the population, including all ages and sexes, is unprecedented in the Andes. Based on the osteological analysis of the individuals from Amato, and through a parsimonious reconstruction of the events that led to their death and decapitation, I present a case for the non-ritual nature of head taking in the south coast during the early EIP. I propose that decapitation likely took place in the context of raiding, conducted primarily for economic reasons. Furthermore, there is sufficient evidence to suggest that the raiding group was from the Southern Nasca Region. These conclusions are significant not only for our understanding of the nature of warfare and head taking during the Early Intermediate Period on the south coast, but they also inform broader questions about inter- and intra-valley interaction and culture change in this part of the preHispanic Andes.
title: How do registered nurses learn about practice? A qualitative study
Creators: name: Thomas, Megan Patricia Louise
Publisher: name: The Open University
Year: 2011

description: Lifelong learning is strongly encouraged within healthcare, through government and professional initiatives. The emphasis of this learning is to positively influence practice thereby enhancing the patient experience and patient care. However, within these initiatives there is little consideration of the impact of this lifelong learning on the individual, nor their ability to engage with it.

This study employed a hermeneutic approach which explored the feelings, perceptions and experiences of a group of registered nurses relating to their learning about practice. The study provides insight into how nurses view themselves professionally and academically.

Data were collected in three ways. Demographic data was collected to situate the sample group. Written and verbal data were collected through the use of meta-planned focus groups (Davies et al 2001). Linguistic metaphor analysis was carried out on the written and verbal data which was coded, categorized and organised into themes.

The study revealed a number of attributes in relation to learning about practice. Whilst many participants were intrinsically motivated to develop new skills and ways of working, they were also extrinsically motivated through the relationships they had with colleagues. It was recognised that a supportive environment and collaborative partnership led to a successful learning experience. However, whilst many of the participants recognised their own need to develop skills of assertiveness, they identified that professional inequalities and the inappropriate use of power within their relationship with colleagues adversely affected their learning.

The findings from the study resulted in the development of a model of support for learning in practice. This is based on the individual nature of learning, the social environment of learning and cultural aspects of learning. These three areas encompassed the feelings, perceptions and experiences of registered nurses related to their learning about practice.

description: The proposal that the creation of international reserves by the IMF be linked with development assistance to less developed countries has become more insistent in recent years. The primary and basic purpose of the Link is to increase the flow of development aid to less developed countries from more developed countries. It is safe to say, however, that if it could be shown that the basic objective cannot be achieved, or only to a small and uncertain extent, the enthusiasm for the Link would quickly die down. While the author does not question the desirability of the basic objective, it is argued that a sizeable increase in the flow of aid cannot be achieved through the Link and that it would be an inefficient method for providing aid.

description: The article presents a detailed description of the money markets in the U.S. In recent years, new markets such as bankers’ acceptances, commercial paper, Negotiable Certificates of Deposit and the external extension of the New York market into Euro-dollars have have been established. Despite the growth in some of these markets, however, the main markets in the U.S. remain those in Government securities and Federal funds. It is through these markets that idle money in the U.S. is mobilised and distributed across the country as a whole. In this context, full use is made of correspondent relationships and both the banks and the dealers attempt to tap every possible source of funds. The intensity of this search for new sources of money has had the effect of binding together much more closely the various parts of the financial mechanism and has made it much more sensitive to Federal Reserve action.

description: Fritz Machlup recently reproposed the issue of the logical foundation underlying the flows of funds denominated in dollars and other “strong” currencies which are traded in the so-called Euro-dollar market. The present paper shows that Machlup’s study picks out only some of the aspects of a more general theory presented elsewhere and underestimates the possibilities to empirical research opened up by the present statistical endowment. The central thrust of the analysis is the incorporation of the demand for and the supply of international liquidity within a unified framework. The authors first discuss the relationship between the U.S. balance of payments and the Eurodollar market. An interpretation of the empirical content to assign to the reserve position of Eurobanks is then suggested. Finally, the authors postpone to an appendix the discussion of Machlup’s six propositions in terms of a more general framework of international financial flows. JEL: E44, F32

title: User experience design and agile development : integration as an on-going achievement in practice
Creators: name: Ferreira, Jennifer
Publisher: name: The Open University
Year: 2012

description: This research investigates how Agile development is combined with User Experience (UX) design. Agile development and UX design have roots in different disciplines and practitioners have to reconcile their perspectives on developing software if they are to work together. To date, there has been no sustained academic study on how Agile developers and UX designers work together in practical settings on a day-to-day basis. The ethnographically-informed research in this dissertation consists of three studies of teams in organisational settings, combined with an analysis of accounts of Agile development and UX design practice found in the literature. Together, they provide evidence for the complex, multifaceted nature of the work that integrates Agile development with UX design.

 The studies of day-to-day practice conducted for this research, found the work of the Agile developers and UX designers to be localised, contingent and purposeful. Agile devolopment and UX design integration, as it was achieved in the teams studied, was negotiated and achieved on a day-to-day basis between the developers and designers. The findings from the analysis of accounts of practice from the literature show that integration is achieved with the right tools, techniques and processes that coordinate between the tasks of the developers and designers and establish a focus on usability and on releasing working software. However, the accounts contain little and conflicting evidence for what constitutes the day-to-day work of Agile developers and UX designers in practical settings and as a result the utility of tools, techniques and processes for practice is not clear.

 Informed by the findings from the accounts in the literature and the studies of practice, five facets emerged as integral to an understanding of how the integration of Agile development and UX design is an on-going achievement in practice. These facets are (1) focus and coordination, (2) mutual awareness, (3) expectations about acceptable behaviour, (4) negotiating progress and (5) engaging with each other. The extent to which these facets enable integration, depend on contextual values concerning the combination of Agile development and UX design endorsed in the organisation. These findings serve to establish conditions which can constrain and enable Agile developers and UX designers in their integration work, while being sympathetic to the values embedded in the settings in which they work.

The kink solution is BPS, and in an appropriate conformal frame all solutions asymptotically approach AdS. The thermodynamics of the Hawking effect yields interesting behavior for the specific heat and hints at a Hawking-Page-like transition at T_{critical} \sim c^{3/2}. We address implications for higher dimensions ("oxidation"), in particular D=3,4 and 11, and comment briefly on AdS/CFT aspects of the kink.

description: Generally speaking, the application of credit ceilings confronts the monetary authorities with a number of political and technical problems, such as the acceptability of distortions of and limits to market forces, the difficulty of administrative controls, and so on. Moreover, a systematic analysis of the economic implications of credit ceilings still has to be made, probably because of the novelty of these policy instruments. The present paper studies the effects and scope of the application of credit ceilings, whether they be considered a substitute for monetary base management or as an additional tool. The analysis is developed on the assumption that the banking system is made of a single large bank with many branches. JEL: E51, E52, G28

Insights from the edge : farmers' perspectives on agricultural viability near urban centres
Creators: name: Frye, Amy Lynn
Publisher: name: University of British Columbia
Year: 2011

description: In British Columbia, Canada, 80 percent of agricultural revenue comes from the same three percent of the land on which 80 percent of the population lives. This close proximity of farmland and urban areas creates a unique context in which agriculture operates. Many factors that influence the viability of farms on the urban edge aren't accounted for by traditional land valuation tools that only consider physical characteristics of the land, such as soil quality, topography and climate. Farmland near urban areas is also affected by factors such as access to customers, conflict with neighbours and municipal bylaws. Many of these non-biophysical factors are becoming increasingly important to farmers due to the growth in direct farm marketing. The goal of this research is to help improve farmland management by providing information with which to update planning and land valuation tools. Specifically, the objective was to assess factors that influence the viability of farmland on the urban edge and expand the criteria by which agricultural land is valued. To do this, interviews were conducted with 29 farmers in British Columbia. The results of this study have implications for land management, edge planning, food security and local food systems. They confirm that a variety of factors unrelated to land's physical characteristics often determine a farm's success or failure. The results indicate that urban-edge agriculture is valuable to British Columbia for both economic and food security reasons, and is characterized by high risks and high rewards. Innovative planning and government support are needed to keep pace with the evolving face of agriculture and ensure that farmers can reap the benefits of an urban-edge location while avoiding its risks.

description: Recent developments in commercial banking in the United States have exerted a profound impact on the financial structure. The present paper focuses on events which led to commercial bank diversification culminating in the formation of the financial congeneric - a bank dominated IBHC. The authors first looks at recent banking history and the factors that shaped a regulatory philosophy tending to restrict diversification and competition within the banking community, leading to the recently passed legislation extending Federal regulation to one-bank holding companies. Some of the more important functionally-related services offered by financial congenerics are then described, apart from the conventional deposit and loan services of commercial banks. Finally, the economic forces that led toward commercial bank diversification into functionally-related areas are examined. JEL: G21, G28

description: To examine if the association between age and post-stroke cognition is mediated by apathy. A cross-sectional investigation was carried out with 389 stroke survivors and informants. Data were collected through the Apathy Evaluation Scale (AES-C) and the Informant Questionnaire for Cognitive Decline in the Elderly (IQCODE). Bivariate analyses were conducted between the IQCODE total score and each of the demographic and clinical characteristics as well as apathy, while Baron and Kenny’s 4-step approach was used to examine the mediating effect of apathy on the association between age and post-stroke cognition. Participants were aged 64.3 years on average, with a mean IQCODE score of 97.6 (SD: 14.8) and a mean AES-C score of 41.3 (SD: 8.0). IQCODE scores were positively correlated with age (r = 0.32, p < 0.001) and apathy (r = 0.54, p < 0.001). Apathy contributed to 24% of the total effect of age on post-stroke cognition, exerting a significant mediating effect on the relationship between age and post-stroke cognition. Apathy may have a significant impact on the cognitive health of stroke survivors. Therefore, the early identification of apathy symptoms could facilitate consideration of potential interventions, such as multisensory and cognitive stimulation, designed to improve cognitive outcomes in this population. Cognitive impairment after stroke is common and has negative impacts on survivors’ rehabilitation and quality of life.Ageing survivors are prone to mood disorders which may be associated with poorer cognitive outcomes.Apathy was found to significantly mediate the relationship between age and post-stroke cognition.Psychological assessments should be carried out regularly to improve cognitive outcomes through the timely recognition and management of apathy.

description: We experimentally demonstrate the dynamical tuning of the acoustic field in a surface acoustic wave (SAW) cavity defined by a periodic arrangement of metal stripes on LiNbO3 substrate. Applying a DC voltage to the ends of the metal grid results in a temperature rise due to resistive heating that changes the frequency response of the device up to 0.3%, which can be used to control the acoustic transmission through the structure. The time scale of the switching is demonstrated to be of about 200 ms. In addition, we have also performed finite element simulations of the transmission spectrum of a model system which exhibit a temperature dependence consistent with the experimental data. The advances shown here enable easy, continuous, dynamical control and could be applied for a variety of substrates.

description: The effects of thermal fluctuations of the mass (horizon area) and electric charge, on the entropy of non-rotating charged {\it macroscopic} black holes, are analyzed using a grand canonical ensemble. Restricting to Gaussian fluctuations around equilibrium, and assuming a power law type of relation between the black hole mass, charge and horizon area, characterized by two real positive indices, the grand canonical entropy is shown to acquire a logarithmic correction with a positive coefficient proportional to the sum of the indices. However, the root mean squared fluctuations of mass and charge relative to the mean values of these quantities turn out to be independent of the details of the assumed mass-area relation. We also comment on possible cancellation between log (area) corrections arising due to {\it fixed area} quantum spacetime fluctuations and that due to thermal fluctuations of the area and other quantities.

Sulla facoltà della distinzione tra moneta interna e moneta estera.

Publisher: name: Moneta e Credito
Year: 2014
Subjects: subject: Money neutrality, monetary policy, money illusion, inside money, outside money, elasticity of price
subject: E52, E40, E31

description: According to neo-classical theory money is neutral and monetary policy in the long run trivial, provided there is no rigidity in prices or incomes, no “money illusion” and that the elasticity of price expectation is not equal to unit. Conversely, according to Gurley and Shaw, the adoption of the distinction between inside and outside money would show that even if all the above conditions were realised, money would not be neutral if, as is true in real life, inside and outside money coexist. They maintain that monetary policy would be neutral only if, and insofar as, there were proportional changes in the quantity of the two types of money. According to the author, however, there appears to be no justification for maintaining that the distinction implies a new condition for the achievement of neutrality, and least of all should it be assumed that it destroys the usefulness of the neutrality of money theorem.

title: Measuring capabilities an empirical investigation of the sen-nussbaum approach to well-being
Creators: name: Hunter, William Mitchell Graham
Publisher: name: The Open University
Year: 2010

description: This thesis argues for the view that Amartya Sen's capabilities approach is a preferable approach to the measurement of welfare by addressing three questions:

 can the capability approach be operationalised?
 what is the relationship between capabilities and satisfaction with life.?
 how do capabilities respond to changes over time?

 Chapter 1 provides a discussion of a widely used economic evaluation model of welfare focussing on some of its key problems and concludes with a discussion of Sen's alternative capabilities approach.

Chapter 2 discusses the three key relationships that Sen uses in evaluating wellbeing and discusses the identification of capabilities based on the account developed by Martha Nussbaum.

description: We explore constraints on the equation of state (EOS) of neutron-rich matter based on microscopic calculations up to nuclear densities and observations of neutron stars. In a previous work we showed that predictions based on modern nuclear interactions derived within chiral effective field theory and the observation of two-solar-mass neutron stars result in a robust uncertainty range for neutron star radii and the EOS over a wide range of densities. In this work we extend this study, employing both the piecewise polytrope extension from Hebeler et al. as well as the speed of sound model of Greif et al., and show that moment of inertia measurements of neutron stars can significantly improve the constraints on the EOS and neutron star radii.

description: We fully solve the quantum geometry of $\Bbb Z_n$ as a polygon graph with arbitrary metric lengths on the edges, finding a $*$-preserving quantum Levi-Civita connection which is unique for $n\ne 4$. As a first application, we numerically compute correlation functions for Euclideanised quantum gravity on $\Bbb Z_n$ for small $n$. We then study an FLRW model on $\Bbb R\times\Bbb Z_n$, finding the same expansion rate as for the classical flat FLRW model in 1+2 dimensions. We also look at particle creation on $\Bbb R\times \Bbb Z_n$ and find an additional $m=0$ adiabatic no particle creation expansion as well as the particle creation spectrum for a smoothed step expansion.

description: The demand for future wireless communication systems is being satisfied for various circumstances through unmanned aerial vehicles (UAVs), which act as flying base stations (BSs). In this letter, we propose an ellipse clustering algorithm that maximizes the user coverage probability of UAV- BSs and avoids inter-cell interference with minimal transmit power. We obtain the coverage of each UAV by adjusting its antenna half-power beamwidth, orientation, and 3D location by minimizing the path loss of the cell-edge user. Simulation results confirm that the proposed algorithm achieves high system throughput and coverage probability with lower transmit power compared to conventional algorithms.

The Baryonic Tully-Fisher relation revisited
Creators: name: Pfenniger, D.
name: Revaz, Y.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The Baryonic Tully-Fisher relation (BTF) can be substantially improved when considering that the galactic baryonic mass is likely to consist not only from the detected baryons, stars and gas, but also from a dark baryonic component proportional to the HI gas. The BTF relation is optimally improved when the HI mass is multiplied by a factor of about 3, but larger factors up to 11-16 still improve the fit over the original one using only the detected baryons. The strength of this improved relation is quantified with up-to-date statistical tests such as the Akaike Information Criterion or the Bayesian Information Criterion. In particular they allow to show that supposing a variable $M_\star/L$ ratio instead is much less significant. This result reinforces the suggestion made in several recent works that mass within galactic disks must be a multiple of the HI mass, and that galactic disks are substantially, but not necessarily fully, self-gravitating.
