Leverage and Asset Bubbles: Averting Armageddon with Chapter 11?
Creators: name: Stiglitz, Joseph E.
name: Miller, Marcus
Publisher: name: Columbia University
Year: 2010
Subjects: Economics

description: An iconic model with high leverage and overvalued collateral assets is used to illustrate the amplification mechanism driving asset prices to 'overshoot' equilibrium when an asset bubble burst--threatening widespread insolvency and what Richard Koo calls a 'balance sheet recession'. Besides interest rates cuts, asset purchases and capital restructuring are key to crisis resolution. The usual bankruptcy procedures for doing this fail to internalise the price effects of asset 'fire-sales' to pay down debts, however. We discuss how official intervention in the form of 'super' Chapter 11 actions can help prevent asset price correction causing widespread economic disruption.

description: Technical innovations for esophageal testing are continuously evolving to help people better understand and treat various esophageal disorders. In this work, efforts have been focused on the developments of two innovative systems for improving the diagnosis of gastroesophageal reflux disease (GERD) and esophageal motility disorders (EMDs). Determining the volume of gastroesophageal reflux (GER) is important for the diagnosis and treatment of GERD. However, a reliable diagnostic method for accomplishing this task is still missing. This research provided an integrated tool for automated monitoring of GER volume. A simple, low-cost ultrasonic probe was developed as a volumetric sensing component and it was combined with a commercially available multichannel intraluminal impedance catheter. The integrated tool was successfully tested in in-vitro laboratory and in-vivo human studies. In-vitro testing results demonstrated the accuracy of the volumetric measurement. In-vivo human testing was undertaken on two healthy human subjects. Results confirmed the feasibility of the proposed system for measuring volume of liquid GER in the vicinity of the ultrasonic probe. The proposed method paved the way towards an improved diagnosis and treatment of GERD. Ambulatory esophageal manometry has been considered the optimal technique for precise classification of various types of EMDs. However, current ambulatory manometry systems are not widely accepted due to their high costs, incomplete circumferential pressure sensing capabilities, and other practical issues. In this study, a novel manometry catheter containing a cost-effective pressure sensor capable of circumferential sensing was presented to overcome these limitations. A portable-size capacitance measurement device was used as an interface between the sensor and a graphical user interface on a personal computer. Experimental results confirmed the feasibility of the new manometry system for measuring circumferential pressure. This study provided a significant contribution towards a disposable esophageal manometry catheter to facilitate a low-cost and reliable ambulatory monitoring of esophageal motility.
Risk and Global Economic Architecture: Why Full Financial Integration May Be Undesirable
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University

Subjects: Economics

description: Integration of global financial markets was supposed to lead to greater financial stability, as risks were spread around the world. The financial crisis has thrown doubt on this conclusion. A failure in one part of the global economic system caused a global "meltdown." The recent crisis has shown that in the absence of appropriate government intervention, privately profitable transactions may lead to systemic risk. This paper provides a general analytic framework within which we can analyze the optimal degree (and form) of financial integration. Within this general framework, full integration is not in general optimal. Indeed, faced with a choice between two polar regimes, full integration or autarky, in the simplified model autarky may be superior.

description: The cognitive complexity of software is a new approach to the functional and semantic complexity of programs, which is a product of the operational complexity and architectural complexity of software. Software cognitive complexity is an emerging measure for the functional complexity of programs complementing the Line of Code (LOC) and Cyclomatic measures. LOC is a linear size measure that is commonly used by industry as a gauge of software complexity [Chelf & Chou 2008]. It assumes that the larger the software system in LOC, the more complex it is [Jay et al. 2009]. However, theoretical and empirical studies indicate that the actual functional complexity of software is not simply proportional to its LOC. Therefore, cognitive complexity is introduced to reveal programs with identical or similar LOC that may have significant variants in their complexities. To enable the study on cognitive complexity and its automatic calculation, a software tool is developed to parse and measure software cognitive complexity of a set of programs from real-world samples. The data and analysis results demonstrate a variety of attributes of software complexities from the facets of symbolic, cyclomatic, functional and cognitive complexities. The design and implementation of a tool, which provides an efficient analyzer not only for cognitive complexity measurement for practitioners and researches, but also for comparative measurements with classic software complexities of LOC and Cyclomatic features. Essentially, a single tool incorporating known classical complexity measures plus the new form of cognitive complexity measures to ease the process of measuring software complexity by eliminating the need for multiple tools while aggregating the results after analyzing in an automatic batch process. Since this specific form of cognitive complexity measurement is new, a measurement tool is not readily available in the software industry and must be developed for use as part of this software engineering research. Finally, through exploratory case studies and investigations, this thesis has characterized practical low values of software cognitive complexity measure, revealed that Wang's original theoretical experimental results and characterizations are applicable to real world software, and shown the potential use of this measure for some phases of software product life such as in capital phase, and operation and maintenance phases.

description: Drought is part of the normal climate variability in the Great Plains and Intermountain Western United States, but recent severe droughts along with climate change projections have increased the interest and need for better understanding of drought science and decision making. The purpose of this study is to understand how the U.S. Department of the Interior's (DOI) federal land and resource managers and their stakeholders (i.e., National Park Service, Bureau of Land Management, Fish and Wildlife Service, Bureau of Reclamation, Bureau of Indian Affairs and tribes, among others) are experiencing and dealing with drought in their landscapes. The Drought Risk and Adaptation in the Interior (DRAI) project is part of a DOI-sponsored North Central Climate Science Center (NC CSC) crosscutting science initiative on drought across the Center's three foundational science areas: 1. Physical climate, 2. Ecosystems impacts and responses, and 3. Human adaptation and decision making. The overarching goal is to learn more about drought within the DOI public lands and resource management in order to contribute to both the NC CSC regional science as well as providing managers and other decision makers with the most salient, credible, and legitimate research to support land and resource management decisions. Here we will present the project approach along with some initial insights (with a focus on grazing lands and related DOI/tribal resource management) learned from the research to date along with its utility for climate adaptation.

description: The prognosis of schizophrenia and other psychotic disorders may be improved through efforts to identify at-risk individuals and to provide early interventions prior to the first episode of psychosis. Psychosis-risk syndrome is gaining recognition as a distinct clinical condition, and may be included as a diagnosis in the upcoming version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). As direct mental health practitioners, social workers are in an ideal position to both address the diverse psychosocial needs and improve the accessibility of services for this difficult-to-define population. As macro-level practitioners, social workers can provide a valuable perspective on ethical issues while advocating to reduce the stigma surrounding the provision of intensive mental health services to individuals struggling with psychosis-risk syndrome.

description: Recent work has revealed a microdomain m cerebral arterial smooth muscle comprised of caveolae and the sarcoplasmic reticulum. Immunolabeling techniques indicate that T-type Ca2+ channels (Cav3.2) and ryanodine receptors localize to this microdomain while L-type Ca2+ channels do not. Based on these observations, we hypothesize that T-type Ca2+ channels play a major role in triggering RyR receptors and consequently in modulating Ca2+ sparks. To address this hypothesis, we developed a detailed tissue-specific biophysical model that can simulate several aspects of Ca2+ sparks in cerebral arterial SMCs by integrating independent formulations of cellular components with different sets of parameter adjustments. The simulation results show that the Calcium Induced Calcium Release (CICR) process can be initiated in a virtual microdomain containing Cav3.2 and RyR channels. These CICR events are repetitive and voltage dependent in that higher depolarization lead to higher CICR frequencies.

description: Perturbed Kerr black holes emit gravitational radiation, which (for the practical purposes of gravitational-wave astronomy) consists of a superposition of damped sinusoids termed quasi-normal modes. The frequencies and time-constants of the modes depend only on the mass and spin of the black hole - a consequence of the no-hair theorem. It has been proposed that a measurement of two or more quasi-normal modes could be used to confirm that the source is a black hole and to test if general relativity continues to hold in ultra-strong gravitational fields. In this paper we propose a practical approach to testing general relativity with quasi-normal modes. We will also argue that the relative amplitudes of the various quasi-normal modes encode important information about the origin of the perturbation that caused them. This helps in inferring the nature of the perturbation from an observation of the emitted quasi-normal modes. In particular, we will show that the relative amplitudes of the different quasi-normal modes emitted in the process of the merger of a pair of nonspinning black holes can be used to measure the component masses of the progenitor binary.

description: The Newns-Anderson model is ubiquitous in studies of the molecular transport in the presence of solvent (outer) reorganization. The present work demonstrates that intramolecular reorganization can also be significant for the transport through molecules with floppy degrees of freedom, for which the Newns-Anderson model can be extended. The expressions of the model parameters deduced from electronic structure calculations for (4, 4')-bipyridine (44BPY) quantitatively differ from those characteristic for outer reorganization due to strong intramolecular anharmonicities. These expressions can be utilized as input in transport calculations for 44BPY-based molecular junctions of experimental interest [Science 301 (2003) 203, J. Am. Chem. Soc. 130 (2008) 16045, Nano Lett. 12 (2012) 354].

description: Abstract
A total of 96 guinea fowl hens (28-32 weeks old) were used to study the effect of photoperiod and dietary innovative materials (DIM) (Monk's pepper and Thyme) on the haematological and serum biochemical indices of guinea fowl hens. The birds were weighed and randomly assigned to eight treatment groups in a 2 (two photoperiods) ×4 (DIM) factorial arrangement in a Completely Randomized Design (CRD). The birds were exposed to two photoperiods of 12 hours of normal light (12 L) and 20 hours of extended light (20 L) period using ECKO 100W solar LED lamp with an average light intensity of 5.78 lux. The four diets used contained 6g of monks pepper (M) and thyme (T)/kg diet in different ratios as follows No DIM, 50M50T, 75M25T, and 25M75T. Each treatment was replicated three times having four birds per replicate. Feed and water were provided ad libitum and after nine months, blood samples were collected for haematological and serum biochemical evaluation. The results indicated that photoperiod significantly (P<0.05) influenced White blood cell (WBC) count and monocytes content while DIM significantly (P<0.05) improved all haematological parameters measured except lymphocytes, heterophils and eosinophils. For serum parameters, birds on extended photoperiod had significantly (p<0.05) higher total protein, globulin and uric acid content but no significant difference (p>0.05) was recorded for albumin. DIM inclusion significantly (p<0.05) affected total protein, globulin and uric acid content. However, albumin content was not significantly (p>0.05) affected. It can be concluded that 12 hours of light and DIM at ratio 25M75T/kg diet improved the blood parameters and general health of guinea fowl hens.

description: We propose a modification in the Sznajd sociophysics model defined on the square lattice. For this purpose, we consider reputation-a mechanism limiting the agents' persuasive power. The reputation is introduced as a time-dependent score, which can be positive or negative. This mechanism avoids dictatorship (full consensus, all spins parallel) for a wide range of model parameters. We consider two different situations: case 1, in which the agents' reputation increases for each persuaded neighbor, and case 2, in which the agents' reputation increases for each persuasion and decreases when a neighbor keeps his opinion. Our results show that the introduction of reputation avoids full consensus even for initial densities of up spins greater than 1/2. The relaxation times follow a log-normal-like distribution in both cases, but they are larger in case 2 due to the competition among reputations. In addition, we show that the usual phase transition occurs and depends on the initial concentration $d$ of individuals with the same opinion, but the critical points $d_{c}$ in the two cases are different.

description: From a geopolitical, economic perspective, Jonathan Sacks, chief rabbi of the United Hebrew Congregation of Britain, takes up a problem that has befuddled theologians, especially over the last half century: how to balance—that is, give equal importance to—both identity and difference. Or, How can I be as committed to my own religion as I am open to others? "On this question," Sacks warns us, "the future of the twenty-first century may turn" (p. 43). Only if we can affirm and feel "the dignity of difference" can we "avoid the clash of civilizations."

description: Total knee arthroplasty is a surgical procedure m which the knee is resurfaced with implants to relieve pam. This thesis presents computed tomography and radiography methods to determine the relative position (kinematics) for the patellofemoral and tibiofemoral joints zn vivo for a full range of motion, as well as parameters related to surgical technique. These methods were used to compare: (1) subjects with gender-specific (GS) versus traditional implant designs, (2) symptomatic versus asymptomatic subjects, and (3) static versus dynamic kinematics. Quality of life (QOL) was also measured. GS implants only had a small but significant difference in patellofemoral translation in early flexion; no other differences were found for the kinematics or QOL. For all symptomatic subjects, differences in kinematics or surgical parameters were found, suggesting the cause for the subject's postoperative pain. Static and dynamic kinematics were comparable in all but one case, where internal/external tibial rotation differed.
European Protestant and Catholic approaches to the world religions: complements and contrasts
Creators: name: Knitter, Paul
Publisher: name: Columbia University
Year: 1975
Subjects: Religion

description: Christians of various traditions must engage in a dialogue concerning their attitudes toward other religions in order to develop a more "positive Christian approach to other religions." Basically, contemporary Protestant theologians and post-Vatican II Catholic theologians agree concerning divine revelation's occurrence in non-Christian faiths. Several examples are given of the contributions of Protestant and Catholic theologians to the understanding of divine revelation through human religions. The content of what is perceived to be revealed through other religions is summarized:  a knowledge of a personalized deity, an insight into the human condition and the human need for redemption, and a sense of the absolute transcendence of the deity. On the issue of salvation within other religions, however, the Protestant theologians under investigation are not so positive. One must have contact with the historical Christ event and understand its significance both psychologically and cognitively. However, Catholic theologians affirm the possibility of salvation outside of Christ. Key issues are: "the universal salvific will of God" and "the relation between revelation and salvation."

description: We develop an efficient method to derive a class of surface states in photonic superlattices. In a kind of infinite bichromatic superlattices satisfying some specific conditions, we obtain a finite portion of their in-gap states, which are superpositions of finite numbers of their unstable Bloch waves. By using these unstable in-gap states, we construct exactly several stable surface states near various interfaces in photonic superlattices. We analytically explore the parametric dependence of these exact surface states. Our analysis provides an exact demonstration for the existence of surface states and would be also helpful to understand surface states in other lattice systems.

description: In the midst of accelerating climatic change and observed weather extremes due to long-term natural variation, as well as our more recent and all-too-efficient anthropogenic transfer of carbon from the earth to the atmosphere, Great Plains Indian Tribes see tremendous clean energy and economic development opportunities on the horizon for mitigation and adaptation literally blowing in the wind. Our centralized electrical energy generation capacity is highly water dependent and our transmission and distribution infrastructure, built over the last half-century, is strung out and exposed across the volatile Upper Great Plains. They are extremely vulnerable and highly susceptible to changes in precipitation and other weather variabilities over both the short and long-term. Our electrical generating capacity inextricably relies upon the surface water resources throughout the Missouri River basin to fuel the federal hydropower generators, and to spin and cool the conventional coal and nuclear thermal plants throughout the region. Our rural transmission and distribution systems that deliver electricity are exposed across vast distances and are extremely vulnerable to a variety of weather related disruptions. American Indian Reservations are also spread across this vast expanse where wind, one of America's most abundant renewable energy resources, can be readily tapped through both community-sized, and large, utility-scaled, distributed generation projects. The economic integration of this variable but abundant resource into the coal and hydropower dominated electrical system can benefit from better planning and forecasting in both the short and long term. This paper examines some critical planning and forecasting issues raised in this context.
Simulations of Prominence Formation in the Magnetized Solar Corona by Chromospheric Heating

description: Starting from a realistically sheared magnetic arcade connecting chromospheric, transition region to coronal plasma, we simulate the in-situ formation and sustained growth of a quiescent prominence in the solar corona. Contrary to previous works, our model captures all phases of the prominence formation, including the loss of thermal equilibrium, its successive growth in height and width to macroscopic dimensions, and the gradual bending of the arched loops into dipped loops, as a result of the mass accumulation. Our 2.5-dimensional, fully thermodynamically and magnetohydrodynamically consistent model mimics the magnetic topology of normal-polarity prominences above a photospheric neutral line, and results in a curtain-like prominence above the neutral line through which the ultimately dipped magnetic field lines protrude at a finite angle. The formation results from concentrated heating in the chromosphere, followed by plasma evaporation and later rapid condensation in the corona due to thermal instability, as verified by linear instability criteria. Concentrated heating in the lower atmosphere evaporates plasma from below to accumulate at the top of coronal loops and supply mass to the later prominence constantly. This is the first evaporation-condensation model study where we can demonstrate how the formed prominence stays in a force balanced state, which can be compared to the Kippenhahn-Schluter type magnetohydrostatic model, all in a finite low-beta corona.
Roman Catholic Approaches to Other Religions: Developments and Tensions
Creators: name: Knitter, Paul
Publisher: name: Columbia University
Year: 1984
Subjects: Religion

description: The article traces stages in the development of Roman Catholic attitudes towards other faiths, with special concern for the question of the uniqueness of Christ. Five stages are identified:  1) exclusive ecclesiocentrism -- "no salvation outside the church"; 2) inclusive ecclesiocentrism -- no salvation without the church; 3) constitutive christocentrism -- Christ working anonymously in the religions; 4) normative christocentrism -- Christ the final norm for all religions; and 5) dialogical theocentrism -- the many religions as many co-equal partners in God. The article urges greater inter-Christian dialogue in exploring the validity of this final stage.

Accelerated aging in COPD : the relationship of telomere length and mortality in COPD
Creators: name: Lee, Jeeyoung
Publisher: name: University of British Columbia

description: The evidence for the role of accelerated aging in COPD progression is growing and the senescence hypothesis is one possible molecular pathway by which COPD develops. Telomeres are used as a biomarker of cellular aging, and cellular aging is accelerated by the presence of oxidative stress and inflammation. Previous studies have shown that telomeres of peripheral blood cells are significantly shorter in COPD patients, but no studies to date explored the relationship of telomere length to important health outcomes such as mortality. Using samples from Lung Health Study (LHS), we examined the role of telomere length and polymorphisms in genes involved in aging process in health outcomes in COPD patients. There were no significant differences in age, sex, BMI, race of cumulative smoking exposure (pack-years) among 4 groups, divided on basis of telomere length. However, the risk of all cause mortality was similar across the first 3 quartiles (short telomere) but dropped significantly in the 4th quartile (longest telomere, hazard ratio (HR), 1.30). Compared to individuals in the 4th quartile of relative telomere length, the remaining participants had significantly higher risk of cancer mortality (HR, 1.48). Smoking status did not make a significant difference in leukocyte telomere length but when compared to non-COPD, age matched control group, all smoker groups in LHS had shorter telomeres. We also investigated the role of SNPs that were previously associated with leukocyte telomere length in disease outcome. Although no SNPs were associated with leukocyte telomere length, several SNPs of telomere biology genes were associated with cardiovascular and lung cancer mortality. The rate of telomere attrition is influenced by both extrinsic factors, such as inflammation and oxidative stress and intrinsic factors such as genetic predisposition. Here, we have shown that accelerated aging of peripheral blood cells, indicated by short telomeres, seems to play a role in disease outcome of COPD. Although we failed to show significant associations between leukocyte telomere length and genetic polymorphisms of telomere regulatory genes, the SNPs may contribute to risk of mortality. Further research is needed to elucidate the pathways underlying these observations.

description: The maintenance of balanced immune responses is vital to the health of an individual. This is of particular importance in the intestine, as it represents a vast immunological challenge due to the enormous antigenic potential of the commensal microbiota. The body has therefore developed a number of homeostatic strategies to ensure that inflammatory reactions are freely able to clear foreign material such as bacteria in a manner that is self-limiting. The dysregulation of these processes, however, can lead to the development of chronic diseases such as inflammatory bowel disease (IBO). A cell type that plays a vital role in maintaining this homeostasis is the macrophage. In this thesis, I have demonstrated how the phagocytosis of bacteria is enhanced in these cells by lipoxins, a family of lipid mediators that are involved in inducing the resolution of inflammation. This phenomenon was associated with a concomitant decrease in pro-inflammatory mediator production, suggesting that lipoxins are able to induce a macrophage phenotype that is geared towards eliminating any residual infections at the end stages of inflammation, and return tissues to sterile homeostasis. The functions of lipoxin were also found to be dependent on the signalling molecule phosphoinositide 3-kinase pl l0y (PI3Ky). This enzyme has previously been shown to be involved in the recruitment of leukocytes to inflamed tissues, and thus its inhibition or genetic knock-out has been shown to effectively treat a number of mouse models of inflammatory disease. We show here that mice deficient in PB Ky are initially protected from acute experimental colitis induced by the haptenizing agent trinitrobenzene sulfonic acid (TNBS), but fail to heal properly due to an inability to clear bacteria that have infected the colonic tissue. Taken together, these studies highlight the importance of bacterial clearance from inflamed tissues, and suggest that the development of novel anti-inflammatory therapies that promote, rather than hinder the antimicrobial functions of phagocytes such as macrophages could be of use in the treatment of IBD.
Graded cluster expansion for lattice systems

description: In this paper we develop a general theory which provides a unified treatment of two apparently different problems. The weak Gibbs property of measures arising from the application of Renormalization Group maps and the mixing properties of disordered lattice systems in the Griffiths' phase. We suppose that the system satisfies a mixing condition in a subset of the lattice whose complement is sparse enough namely, large regions are widely separated. We then show how it is possible to construct a convergent multi-scale cluster expansion.

A common creation story? interreligious dialogue and ecology
Creators: name: Knitter, Paul
Publisher: name: Columbia University
Year: 2000
Subjects: Religion

description: This essay explores the contemporary proposal that our scientific understanding of the earth—how it originated and how it functions—can serve as a common creation story for all religions and as the basis, therefore, for interreligious dialogue. Recognizing the danger that such a proposal can become another "meta-narrative" imposed by the West, the author suggests that these dangers might be avoided if the religious communities approach the earth first of all as an ethical story rather than a creation story. By first taking up, together, the ethical challenges of an endangered planet, the religions can determine the common ground on which they might, as a second step, hear each other's religious stories about the earth and develop, together, a common creation story. The shared praxis of ecological engagement can become the common ground for deeper ecological religious dialogue.
