Growth with Exhaustible Natural Resources: Efficient and Optimal Growth Paths
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University
Year: 1974
Subjects: Economics

description: The proposition that limited natural resources provide a limit to growth and to the sustainable size of population is an old one. The natural resource that was the centre of the discussion in Malthus' day was land; more recently, some concern has been expressed over the limitations imposed by the supplies of oil, or more generally, energy sources, of phosphorus, and of other materials required for production. Those who predicted imminent doom in the nineteenth century were obviously wrong. Were they simply wrong about the immediacy of catastrophe, or did they leave out something fundamental from their calculations? There are at least three economic forces offsetting the limitations imposed by natural resources: technical change, the substitution of man-made factors of production (capital) for natural resources, and returns to scale. This study is an attempt to determine more precisely under what conditions a sustainable level of per capita consumption is feasible, to characterize steady state paths in economies with natural resources, and to describe the optimal growth path of the economy, in particular to derive the optimal rate of extraction and the optimal savings rate in the presence of exhaustible natural resources.

A light Higgs scenario based on the TeV-scale supersymmetric strong dynamics

description: We consider a model based on the supersymmetric QCD theory with N_c=2 and N_f=3. The theory is strongly coupled at the infrared scale Λ_H. Its low energy effective theory below Λ_H is described by the supersymmetric standard model with the Higgs sector that contains four iso-spin doublets, two neutral iso-spin singlets and two charged iso-spin singlets. If Λ_H is at the multi-TeV to 10 TeV, coupling constants for the F-terms of these composite fields are relatively large at the electroweak scale. Nevertheless, the SM-like Higgs boson is predicted to be as light as 125 GeV because these F-terms contribute to the mass of the SM-like Higgs boson not at the tree level but at the one-loop level. A large non-decoupling effect due to these F-terms appears in the one-loop correction to the triple Higgs boson coupling, which amounts to a few tens percent. Such a non-decoupling property in the Higgs potential realizes the strong first order phase transition, which is required for a successful scenario of electroweak baryogenesis.

description: A quantum coherent interface between optical and microwave photons can be used as a basic building block within a future quantum information network. The interface is envisioned as an ensemble of rare-earth ions coupled to a superconducting resonator, allowing for coherent transfer between optical and microwave photons. Towards this end, we have realized a hybrid device coupling a Er$^{3+}$ doped Y$_2$SiO$_5$ crystal in a superconducting coplanar waveguide cavity. We observe a collective spin coupling of 4 MHz and a spin linewdith of down to 75 MHz.

Stratégies matrimoniales et émigration vers l’Amérique au 18e siècle: la maison Berrio de La Bastide Clairence
Creators: name: Force, Pierre
Publisher: name: Columbia University
Year: 2013

description: Prior to the massive emigration to South America in the 19th century, rural communities in the Western French Pyrenees produced a significant emigration to Saint-Domingue and other Caribbean islands. This study focuses on the connections between migratory movements and the organization of these communities as “house societies” (Lévi-Strauss) in which the continuity of the “house” was paramount and no new “houses” could be added. Using a micro-historical approach, it analyzes the complex role of inheritance rights in the decision to emigrate, and reconstructs the networks that made emigration possible. Against the traditional image of the son who had to leave because he was deprived of his share of inheritance, it shows that the migration of cadets had the full support of the family group. It also argues that emigration supported the “house system” and undermined it at the same time.

To Negotiate a Carbon Tax: A Rough Map of Policy Interactions, Tradeoffs, and Risks
Creators: name: Gundlach, Justin M.
Publisher: name: Columbia University
Year: 2017
Subjects: Carbon taxes
Carbon dioxide mitigation

description: Sooner or later, the federal government will assign a price to carbon dioxide emissions via legislation. The contents of that legislation will reflect negotiated agreement—built on various political tradeoffs—over a host of policy issues, ranging from taxes to energy efficiency standards. These tradeoffs would implicate not only the scope and price assigned by the carbon pricing policy, but also the policies with which it would interact. This paper anticipates that price will take the form of a carbon tax and describes interactions between that tax and various existing and proposed policies relating to climate change, energy, and environmental protection. Specifically, it proposes a typology for those interactions and applies it to characterize particular policies. It also notes how trading off particular policies for a more robust carbon tax could undermine the climate change mitigation goal of such a tax.
Examining a model of self-conscious emotions : the relationship of physical self-perception and shame and guilt proneness with appraisals in the experience of body-related shame and guilt
Creators: name: Brune, Sara Marlene
Publisher: name: University of British Columbia
Year: 2011

description: Self-conscious emotions such as shame and guilt are powerful emotions that can influence an individual’s behaviours and cognitions in many daily activities. These emotions can function as motivators, resulting in increased effort or change of action to reduce or avoid feeling the emotion again. Although considerable research exists regarding self-conscious emotions, little has been done to examine these emotions in relation to the body (Sabiston, Brunet, Kowalski, Wilson, Mack, & Crocker, 2010). Using Tracy and Robins’ (2004) model of self-conscious emotions, the purpose of this study was to examine (a) physical self-concept (PSC) and shame and guilt proneness as predictors of body-related shame and guilt and (b) the mediating role of specific attributions on the relationship in (a). Based on the model, it was hypothesized that shame would be related to stable, global, and uncontrollable attributions whereas guilt would be related to unstable, specific and controllable attributions. These attributions would mediate any effect of physical self-concept, shame proneness, and guilt proneness on body-related shame and guilt. Female participants (N = 284; Mean age = 20.6 ± 1.9 yrs) completed measures of PSC and shame and guilt proneness before reading a hypothetical scenario designed to elicit a negative body-related emotional response, followed by assessment of state shame and guilt and attributions. Shame proneness and PSC were significant predictors of body shame (β = .49; β = -.11) and guilt (β = .41; β = -.14). Control attributions mediated the relationship of PSC with shame and guilt and shame-proneness with body shame. Global attributions mediated the relationship of shame proneness with body shame. Control (β = -.16), stability (β = .16), and global (β = .20) attributions were significant predictors of body guilt, while global (β = .30) and control (β = -.19) attributions were significant predictors of body shame. The study provides partial support for Tracy and Robins’ model for predicting shame, but little support for predicting guilt.
A method for converting aqueous demetallization products into dispersed metal oxide nanocatalysts in heavy oil

Publisher: name: University of Calgary

description: Bibliography: p. 76-82
description: Metallic heteroatoms deactivate expensive catalyst and, thus, should be removed at early stages during crude oil processing. Electro and biological demetallization are examples of two emerging techniques which remove the metallic heteroatoms; mainly nickel and vanadium, into ions or ionic complexes ultimately residing in the aqueous phase of a two phase water/oil system. This work investigates the conversion of the aqueous metallic species into metal oxide nanoparticles, which are effective upgrading catalysts, dispersed in the oil phase. The conversion step commenced in-situ within a water-in-oil emulsion structure, and the resultant nanoparticles remain very well dispersed in the heavy oil phase. The product nanoparticles were characterized, after successful collection from the oil phase, using X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy dispersive X-Ray spectroscopy (EDX). Despite the complexity of the heavy oil system, results confirmed the in-situ formation of NiO and V2 05 nanoparticles with mean sizes of 20 and 15 nm, respectively. Some aggregates have, nevertheless, formed, due to the relatively high temperature requirement of the method. Investigating the catalytic role of the as-prepared nanoparticles was limited to the NiO nanoparticles, since only low concentrations of V20s could be prepared. An attempt to increase the concentration of dispersed V2 05 by using precursors with higher solubility in water was not successful. A semi-batch reactor setup was employed to investigate the catalytic hydrocracking of heavy oil in the presence of dispersed NiO nanoparticles. On the other hand, batch reactor arrangement was employed to study the thermalcracking of heavy oil in the presence of dispersed NiO nanoparticles.

description: We study the electronic transport through a spin-1 molecule in which mechanical stretching produces a magnetic anisotropy. In this type of device, a vibron mode along the stretching axis will couple naturally to the molecular spin. We consider a single molecular vibrational mode and find that the electron-vibron interaction induces an effective correction to the magnetic anisotropy that shifts the ground state of the device toward a non-Fermi liquid phase. A transition into a Fermi liquid phase could then be achieved, by means of mechanical stretching, passing through an underscreened spin-1 Kondo regime. We present numerical renormalization group results for the differential conductance, the spectral density, and the magnetic susceptibility across the transition.

The Spectrum of the Diffuse Galactic Light I: The Milky Way in Scattered Light

description: We measure the optical spectrum of the Diffuse Galactic Light (DGL) -- the local Milky Way in reflection -- using 92,000 blank-sky spectra from the Sloan Digital Sky Survey (SDSS). We correlate the SDSS optical intensity in regions of blank sky against 100 micron intensity independently measured by the COsmic Background Explorer (COBE) and InfraRed Astronomy Satellite (IRAS) satellites, which provides a measure of the dust column density times the intensity of illuminating starlight. The spectrum of scattered light is very blue and shows a clear 4000 Angstrom break and broad Mg b absorption. This is consistent with scattered starlight, and the continuum of the DGL is well-reproduced by a simple radiative transfer model of the Galaxy. We also detect line emission in Hα, Hβ, [N II], and [S II], consistent with scattered light from the local interstellar medium (ISM). The strength of [N II] and [S II], combined with upper limits on [O III] and [He I], indicate a relatively soft ionizing spectrum. We find that our measurements of the DGL can constrain dust models, favoring a grain size distribution with relatively few large grains. We also estimate the fraction of high-latitude Hαwhich is scattered to be 19+/-4%.

description: The study of the ferrites YBaFe4-xGaxO7 shows that the substitution of Ga for Fe in YBaFe4O7 stabilizes the hexagonal symmetry for 0.40 < x < 0.70, at the expense of the cubic one. Using combined measurements of a. c. and d. c. magnetization, we establish that Ga substitution for Fe in YBaFe4O7 leads to an evolution from a geometrically frustrated spin glass (for x = 0) to a cationic disorder induced spin glass (x = 0.70). We also find an intermediate narrow range of doping where the samples are clearly phase separated having small ferrimagnetic clusters embedded in a spin glass matrix. The origin of the ferrimagnetic clusters lies in the change in symmetry of the samples from cubic to hexagonal (and a consequent lifting of the geometrical frustration) as a result of Ga doping. We also show the presence of exchange bias and domain wall pinning in these samples. The cause of both these effects can be traced back to the inherent phase separation present in the samples.

Il mondo rovesciato

description: Despite its title, this book does not belong to the tradition of such studies as James J. Wilhelm's The Cruelest Month or George Economou's The goddess Natura in Medieval Literature. That is, it provides no survey of the topos of the World Turned Upside Down (both Ernst Robert Curtius and the topos as such are mentioned only in passing, 74f.); rather, it is an au courant consideration of some genres which fall within the upside down domain: the Old French resverie, fatrasie, fatras, and-tangentially-the Italian frottola. "Il mondo rovesciato" is, then, not a theme to be pursued, but the author's emblem for specific poetic nonsense forms in which normal function are reversed and the world is plunged into primeval chaos.

description: We present a methodology for summarization of news about current events in the form of briefings that include appropriate background (historical) information. The system that we developed, SUMMONS, uses the output of systems developed for the DARPA Message Understanding Conferences to generate summaries of multiple documents on the same or related events, presenting similarities and differences, contradictions, and generalizations among sources of information. We describe the various components of the system, showing how information from multiple articles is combined, organized into a paragraph, and finally, realized as English sentences. A feature of our work is the extraction of descriptions of entities such as people and places for reuse to enhance a briefing.

description: Blue Valley Ranch is the foundation sponsor of our Congress. This all day excursion included stops highlighting its habitat improvement and agricultural programs with discussion of management methods and monitoring results. Blue Valley Ranch is a 25,000 acre (10,100 hectare) conservation property located in Grand and Summit Counties in north-central Colorado. The ranch supports a diversity of mountain vegetation communities, beginning in the Blue River corridor at 7,400 ft (2,250 m), and rising in elevation through mountain meadows and shrublands, aspen, lodgepole and other mixed conifer ecosystems to over 9,000 ft (2,740 m). As a working ranch, Blue Valley also produces hay, cattle and bison and supports a diversity of wildlife species. Blue Valley Ranch's broad-scale conservation goals for land stewardship include agricultural production, building resilient ecosystems for wildlife habitat and local communities, and providing non-commercial recreational opportunities. Integrating these diverse goals is the ranch's largest single challenge, but a collaborative planning process helps to use information and expertise from a similarly diverse team of ranch staff, university resources, outside consultants and local agencies in making management decisions. The ranch has intensively created stream improvements building new water structures, wetlands, streams, and improved riparian corridors for fish, waterfowl, song birds, and mammals. The ranch has intensively harvested lodgepine forests that were killed by bark beetle infestations, encouraged aspen regeneration, and they manage elk to produce trophy class animals while also balancing animal numbers on the ranch, through controlled public access, to prevent over consumption of new aspen regeneration and other habitats. Pronghorn, turkeys and sharptail grouse have been successfully introduced onto the ranch and surrounding properties. A highway overpass for ungulate and other animal movements will be installed through the leadership and financial support of the ranch. The ranch owner and employees have added value to the rural community and the ranch serves as an example of intensive management. Thank you to Blue Valley Ranch for their sponsorship of the event and also for their generosity of this field trip.

description: State estimation is a type of an inverse problem in which some amount of observed data needs to be processed using computer algorithms (which are designed using analytical techniques) to infer or reconstruct the underlying model that produced the data. Due to the ubiquity of data and interconnected control systems in the present day, many engineering domains have become replete with inverse problems that can be formulated as state estimation problems. The interconnectedness of these control systems imparts the associated state estimation problems with distinctive structural properties that must be taken into consideration. For instance, the observed data could be high-dimensional and have a dependency structure that is best described by a graph. Furthermore, the control systems of today interface with each other and with the internet, bringing in new possibilities for large-scale collaborative sensor fusion, while also (potentially) introducing new sources of disturbances, faults, and cyberattacks. The main thesis of this document is to investigate the unique challenges related to the issues of robustness, resilience (to faults and cyberattacks), and scalability of state estimation algorithms. These correspond to research questions such as, "Does the state estimation algorithm retain its performance when the measurements are perturbed by unknown disturbances or adversarial inputs?" and "Does the algorithm have any bottlenecks that restrict the size/dimension of the problems that it could be applied to?". Most of these research questions are motivated by a singular domain of application: autonomous navigation of unmanned aerial vehicles (UAVs). Nevertheless, the mathematical methods and research philosophy employed herein are quite general, making the results of this document applicable to a variety of engineering tasks, including anomaly detection in time-series data, autonomous remote sensing, traffic monitoring, coordinated motion of dynamical systems, and fault-diagnosis of wireless sensor networks (WSNs), among others.
Beyond Bell's Theorem: Correlation Scenarios

description: Bell's Theorem witnesses that the predictions of quantum theory cannot be reproduced by theories of local hidden variables in which observers can choose their measurements independently of the source. Working out an idea of Branciard, Rosset, Gisin and Pironio, we consider scenarios which feature several sources, but no choice of measurement for the observers. Every Bell scenario can be mapped into such a \emph{correlation scenario}, and Bell's Theorem then discards those local hidden variable theories in which the sources are independent. However, most correlation scenarios do not arise from Bell scenarios, and we describe examples of (quantum) nonlocality in some of these scenarios, while posing many open problems along the way. Some of our scenarios have been considered before by mathematicians in the context of causal inference.

description: We formalize the idea that when managers require external investment to expand, higher-skilled firms will be more likely to diversify in equilibrium, even though managers can exploit asymmetric information about their ability to raise capital from investors. We exploit the timing of new fund launches in the hedge fund industry to distinguish between agency and capability effects in firm product diversification decisions, using a large survivor-bias-free panel data set on the hedge fund industry from 1994 to 2006. Empirically we show that diversifying firms' excess returns are high relative to those of other firms prior to diversification and fall within firm following diversification, but are six basis points higher per month per unit of risk ex post compared to a matched sample of focused firms. The evidence suggests that managers exploit asymmetric information about their own ability to time diversification decisions; yet, the discipline of markets ensures that better firms diversify, on average. The results provide large-sample empirical evidence that agency effects and firm capabilities jointly influence diversification decisions.

We calculate and analyze the steady state, collective-excitation modes and instability of MPCs. Within excitation modes, there exist Nambu-Goldstone modes that can reveal the pattern of the spontaneous symmetry breaking of MPCs. Bifurcation of the stable and unstable modes is identified in terms of the pumping power and spot size. The unstable mechanism associated with the inward supercurrent flow is characterized by the existence of a supersonic region within the condensate.

description: The electronic structure and the anisotropy of the Al - N π and σ chemical bonding of wurtzite AlN has been investigated by bulk-sensitive total fluorescence yield absorption and soft x-ray emission spectroscopies. The measured N K, Al L1, and Al L2,3 x-ray emission and N 1s x-ray absorption spectra are compared with calculated spectra using first principles density-functional theory including dipole transition matrix elements. The main N 2p - Al 3p hybridization regions are identified at -1.0 to -1.8 eV and -5.0 to -5.5 eV below the top of the valence band. In addition, N 2s - Al 3p and N 2s - Al 3s hybridization regions are found at the bottom of the valence band around -13.5 eV and -15 eV, respectively. A strongly modified spectral shape of Al 3s states in the Al L2,3 emission from AlN in comparison to Al metal is found, which is also reflected in the N 2p - Al 3p hybridization observed in the Al L1 emission. The differences between the electronic structure and chemical bonding of AlN and Al metal are discussed in relation to the position of the hybridization regions and the valence band edge influencing the magnitude of the large band gap.

description: There have been few studies predicting institutionalization or death in home care settings. We examined risk factors for nursing home placement (NHP) and death among home care patients. A prospective one-year follow-up study. Persons aged ≥65 years living in Eastern Finland and receiving regular home care services (n = 293). Risk factors for NHP or death were investigated using Cox proportional hazards model. Explanatory variables included demographics, health status (Charlson Comorbidity Index, CCI), physical (Timed Up and Go, TUG), and cognitive (Mini-Mental State Examination, MMSE) functioning, Basic and Instrumental Activities of Daily Living (BADL, IADL) and mood (Geriatric Depression Scale, GDS-15). Of the 293 patients (mean age 82.6 years, 70.6% women), 27 (9.2%) moved to a nursing home and 25 (6.9%) died during the follow-up (mean 350 days). The combined outcome of NHP or death was predicted by BADL (HR 0.73, CI 95% 0.62–0.86), IADL (0.75, 0.65–0.87) MMSE (0.92, 0.87–0.96), and TUG (1.02, 1.01–1.03). NHP alone was predicted by BADL (0.62, 0.50–0.78), IADL (0.57, 0.45–0.73), and MMSE (0.88, 0.82–0.94) and mortality by TUG (1.02, 1.01–1.03). Basic measures of functioning can be used to identify high-risk patients in home care. Decreasing BADL, IADL and MMSE predict NHP and longer TUG-times death within a year. Factors associated with institutionalization or death in community-dwelling older populations are studied comprehensively but far less in known about the risks in home care settings Lower BADL, IADL and MMSE scores predict NHP, and a longer TUG time predicted death within a one-year timeframe among home care patients. The basic tests of functioning and mobility can be used to identify high-risk patients in home care. Identification of high-risk patients may also help in targeting of care and rehabilitation

File-based autobiographies after 1989
Creators: name: Roy, Catherine Karen
Publisher: name: University of British Columbia
Year: 2011

description: This study analyzes four autobiographical accounts written after the fall of the Berlin Wall by former data subjects, i.e., by individuals who have been under the surveillance of the East German Stasi (Staatssicherheit). Following a suggestion by Cornelia Vismann, I refer to these texts as “file-based autobiographies.” The term reflects the fact that they were written in response to the opening of the Stasi archives and the passing of the Stasi Files Act, which allowed data subjects to access their files. By constructing narratives using files written and compiled by informers and secret police officials rather than relying on their own, personal memories, these data subjects challenge the traditional aesthetics of autobiographies and subvert the usual expectations of autobiographical reading. “File-based autobiographies" constitute nothing less than a new autobiographical sub-genre. Rather than offering a personal story that begins in early childhood and ends later in life, data subjects engage in a revision of their lives using files written by a hostile third party. The four case studies show how people under surveillance may need to draw on such documents, even if they are inaccurate, in order to support their claims of authenticity and thus fulfill the autobiographical pact. In this way, these autobiographers acquire and re-functionalize the hostile documents, thus challenging the original purposes for which the files were kept. They show that using their files not only results in unexpected memory processes, but is also a political and literary process that supports their personal agendas and targets particular audiences. Access to and subsequent use of their files gives them the authority to discuss their reaction to the opening of the Stasi files as well as the records themselves.
Review of Kenelm Foster and Patrick Boyde, eds., Cambridge Readings in Dante's "Comedy"
Creators: name: Barolini, Teodolinda
Publisher: name: Columbia University
Year: 1984
Subjects: Romance literature

description: This Volume constitutes a sentimental as well as chronological sequel to a previous collection of lecturae on the Comedy published by Cambridge University Press, entitled The Mind of Dante; whereas the earlier effort was edited by Uberto Limentani, the  current volume consists of ten essays dedicated to Professor Limentani by his colleagues on the occasion of his retirement. The editors take care to point out in the  preface that the essays were intended as lectures for nonspecialists (indeed, footnotes  are kept to a minimum); whatever the cause, these Cambridge readings are, as a group, characterized by an elucidative rather than critical zeal, which tends to make for a competent but somewhat plodding approach to the Comedy

Dante and Francesca da Rimini: Realpolitik, Romance, Gender
Creators: name: Barolini, Teodolinda
Publisher: name: Columbia University
Year: 2000
Subjects: Romance literature

description: While we are accustomed to Dante's appropriations ad revisions of history, the case of Francesca da Rimini (Inf. 5.73-142) is rather different from the norm, since in her case no trace remains of the historical record that the poet could have appropriated. There is no completely independent documentation of Francesca's story; we are indebted for what we know to Dante and to his commentators. A fourteenth-century chronicler of Rimini, Marco Battagli, alludes in passing to the event, but his history was written in 1352, thus postdating by three decades Dante's death in 1321.Therefore, Battagli's passing and indirect reference (to which we shall return in due course) serves at best as plausibly independent confirmation of an occurrence about which the contemporary historical record is silent. That silence is broken by Dante.By reintegrating history-including the silence of history-into our reading of canto, we restore a context in which to remember that in the case of Francesca da Rimini Dante is the historian of record: in effect he saved Francesca from oblivion, giving her a voice and a name.

A Phase Transition for Circle Maps and Cherry Flows

description: We study $C^{2}$ weakly order preserving circle maps with a flat interval. The main result of the paper is about a sharp transition from degenerate geometry to bounded geometry depending on the degree of the singularities at the boundary of the flat interval. We prove that the non-wandering set has zero Hausdorff dimension in the case of degenerate geometry and it has Hausdorff dimension strictly greater than zero in the case of bounded geometry. Our results about circle maps allow to establish a sharp phase transition in the dynamics of Cherry flows.
The missing compact star of SN1987A: a solid quark star?

description: To investigate the missing compact star of Supernova 1987A, we analyzed both the cooling and the heating processes of a possible compact star based on the upper limit of observational X-ray luminosity. From the cooling process we found that a solid quark-cluster star, which has a stiffer equation of state than that of conventional liquid quark star, has a heat capacity much smaller than a neutron star. It can cool down quickly, which can naturally explain the non-detection of a point source (neutron star or quark star) in X-ray band. On the other hand, we consider the heating process from magnetospheric activity and possible accretion, and obtain some constraints to the parameters of a possible pulsar. We conclude that a solid quark-cluster star can be fine with the observational limit in a large and acceptable parameter space. A pulsar with a short period and a strong magnetic field (or with a long period and a weak field) would has luminosity higher than the luminosity limit if the optical depth is not large enough to hide the compact star. The constraints of the pulsar parameters can be tested if the central compact object in 1987A is discovered by advanced facilities in the future.
