Review of Research Techniques for Clinical Social Workers. By Tony Tripodi and Irwin
Epstein. New York: Columbia University Press, 1980
Creators: name: Mullen, Edward Joseph
Publisher: name: Columbia University
Year: 1982
Subjects: Social service

description: Tripodi and Epstein's perspective illustrates the key assumptions in this new
view. Its pragmatic thrust places value on practice that is effective, efficient, and
accountable. A rational, problem-solving process is proposed as the means to
these pragmatic objectives. Intervention is to be based on knowledge obtained
and tested through research methods. To the extent possible, this knowledge
base is to be empirically grounded, objective, eclectic, and open to critical
discussion. And, knowledge-based practice is seen as driven by skepticism as
well as by the ongoing search for new and better methods. From such a perspective
research and practice are seen as not only compatible but fundamentally
related.
Tripodi and Epstein have sought to link research concepts and techniques
with the essentials of clinical practice. Research procedures are presented as
practice tools relevant for obtaining information regarding diagnostic assessment,
treatment implementation, and evaluation. These three phases of the
problem-solving process are seen as reflecting critical areas of decision making
in clinical practice, and the various research techniques presented are viewed as
useful means for informing those decisions. The authors do not attempt an
exhaustive presentation of research methods, but focus on those they consider
easily learned and readily applied. The discussion includes a consideration of
the use of research interviewing, questionnaires, available instruments, systematic
observation, content analysis, client self-monitoring forms, rating scales, survey and time-series designs. Basic techniques of data analysis are considered.
Principles for review of the research literature are discussed, especially from the
perspective of facilitating selection of treatment techniques. The book is organized
into three parts corresponding to each of the three phases of the problem solving
process. The chapters in each part present various research techniques
considered most useful for informing the decisions to be made at that stage.
Each chapter provides principles for implementing the research techniques
under discussion, practice examples, a research exercise, and a brief bibliography.

description: We analyze the influence of the Mg concentration on several important properties of the band structure of ZnMgO alloys in wurtzite structure using ab initio calculations. For this purpose, the band structure for finite concentrations is defined in terms of the Bloch spectral density, which can be calculated within the coherent potential approximation. We investigate the concentration dependence of the band gap and the crystal-field splitting of the valence bands. The effective electron and hole masses are determined by extending the effective mass model to finite concentrations. We compare our results with experimental results and other calculations.

Extending the sufficient component cause model to describe the Stable Unit Treatment Value Assumption (SUTVA)

description: Causal inference requires an understanding of the conditions under which association equals causation. The exchangeability or no confounding assumption is well known and well understood as central to this task. More recently the epidemiologic literature has described additional assumptions related to the stability of causal effects. In this paper we extend the Sufficient Component Cause Model to represent one expression of this stability assumption--the Stable Unit Treatment Value Assumption. Approaching SUTVA from an SCC model helps clarify what SUTVA is and reinforces the connections between interaction and SUTVA.

description: RAVE, the unbiased magnitude limited survey of the southern sky stars, contained 456,676 medium-resolution spectra at the time of our analysis. Spectra cover the CaII IRT range which is a known indicator of chromospheric activity. Our previous work (Matijevič et al. 2012) classified all spectra using locally linear embedding. It identified 53,347 cases with a suggested emission component in calcium lines. Here we use a spectral subtraction technique to measure the properties of this emission. Synthetic templates are replaced by the observed spectra of non-active stars to bypass the difficult computations of non-LTE profiles of the line cores and stellar parameter dependence. We derive both the equivalent width of the excess emission for each calcium line on a 5Å wide interval and their sum EW_IRT for ~44,000 candidate active dwarf stars with S/N>20 and with no respect to the source of their emission flux. From these ~14,000 show a detectable chromospheric flux with at least 2σ confidence level. Our set of active stars vastly enlarges previously known samples. Atmospheric parameters and in some cases radial velocities of active stars derived from automatic pipeline suffer from systematic shifts due to their shallower calcium lines. We re-estimate the effective temperature, metallicity and radial velocities for candidate active stars. The overall distribution of activity levels shows a bimodal shape, with the first peak coinciding with non-active stars and the second with the pre main-sequence cases. The catalogue will be publicly available with the next RAVE public data releases.

Services for the newly dependent: An assessment

Subjects: Social service

description: The number of people receiving public assistance in the United
States rose from an estimated 6.2 million persons in 1950 to 14.4
million in February 1971-two decades of unparalleled economic
growth. It was in this climate that the Community Service Society of
New York (CSS) and the City Department of Social Services (DSS)
in November 1966 undertook a service demonstration to test an
approach to helping newly dependent public assistance families.
This article reports the results of that demonstration.
This effort began with the assumption that many families receiving
public assistance for the first time were in need not only of
financial help but also of skilled individualized counseling. It was
assumed that many of these families would be applying for public
assistance because of serious personal and social problems in
addition to their economic situations. That is, families would be
seeking help following crises such as death, marital dissolution, job
loss, and so forth. In such situations it was proposed that skilled
individualized counseling would help families cope with their feelings
and changed situations and, over time, would facilitate their
adjustment. It was expected that many of these families would need
help finding and using community resources, such as low-cost health
services, housing, employment, and job-training programs. Unless
individualized professional casework was made available in addition
to financial assistance, it was thought that many of these families
would be unable to deal effectively with these problems. Some
critics of the public welfare system suggested that the absence of
professional counseling services was contributing to the rapidly
growing public welfare rolls. They held that the situations leading to
a family's need for public assistance were not usually dealt with by
the current welfare system, with the result that many families that
could otherwise return to independent functioning remained chronically
on public assistance. The effects of this chronic dependency
and absence of needed services were viewed as detrimental both to
society and to the individuals involved. In line with this view, it was
held that professional social caseworkers were especially equipped,
through their dual skills in personal counseling and environmental
intervention, to provide needed services.
Review of Agency-based Social Work: Neglected Aspects of Clinical Practice. By Harold
Weissman, Irwin Epstein, and Andrea Savage. Philadelphia: Temple University
Press, 1984
Creators: name: Mullen, Edward Joseph
Publisher: name: Columbia University
Year: 1985
Subjects: Social service

description: Weissman, Epstein, and Savage make a unique and important contribution
through their publication of Agency-based Social Work. They create a vision of
what clinical social work practice could become, and they describe practice
roles that if adopted could result in effective services pertinent to the needs
of disadvantaged populations. Essentially, this book presents an argument for
the centrality of administrative (organizational) roles in agency-based clinical
practice. In addition, the rich descriptions make the learning of such roles
feasible.
The authors present results of a NIHM-funded project that sought to identify
the administrative skills and knowledge involved in clinical social work, and
to develop as well as evaluate a curriculum for training M.S.W. students in
the administrative aspects of their practice. Although the book is described
as the project's major effort to disseminate its central ideas, no discussion of
the curriculum is provided. Rather, the volume focuses on a description of
administrative roles performed by clinical social workers. As a result, the book
does not address the difficult curricular issues that the project must have
encountered, and that educators seeking to incorporate these ideas into existing
curricula will have to address.

description: We compare methods to resum logarithms in event shape distributions as they have been used in perturbative QCD directly and in effective field theory. We demonstrate that they are equivalent. In showing this equivalence, we are able to put standard soft-collinear effective theory (SCET) formulae for cross sections in momentum space into a novel form more directly comparable with standard QCD formulae, and endow the QCD formulae with dependence on separated hard, jet, and soft scales, providing potential ways to improve estimates of theoretical uncertainty. We show how to compute cross sections in momentum space to keep them as accurate as the corresponding expressions in Laplace space. In particular, we point out that that care is required in truncating differential distributions at N$^k$LL accuracy to ensure they match the accuracy of the corresponding cumulant or Laplace transform. We explain how to avoid such mismatches at N$^k$LL accuracy, and observe why they can also be avoided by working to N$^k$LL$'$ accuracy.

description: Although many symptoms of Major Depressive Disorder (MDD) are assessed through patient-report, there are currently no patient-reported outcome (PRO) instruments that incorporate documented evidence of patient input in PRO instrument development. A review of existing PROs used in MDD suggested the need to conduct qualitative research with patients with MDD to better understand their experience of MDD and develop an evaluative instrument with content validity. The aim of this study was to develop a disease-specific questionnaire to assess symptoms important and relevant to adult MDD patients. The questionnaire development involved qualitative interviews for concept elicitation, instrument development, and cognitive interviews to support content validity. For concept elicitation, ten MDD severity-specific focus group interviews with thirty-eight patients having clinician-confirmed diagnoses of MDD were conducted in January 2009. A semi-structured discussion guide was used to elicit patients' spontaneous descriptions of MDD symptoms. Verbatim transcripts of focus groups were coded and analyzed to develop a conceptual framework to describe MDD. A PRO instrument was developed by operationalizing concepts elicited in the conceptual framework. Cognitive interviews were carried out in patients (n = 20) to refine and test the content validity of the instrument in terms of item relevance and comprehension, instructions, recall period, and response categories. Concept elicitation focus groups identified thirty-five unique concepts falling into several domains: i) emotional, ii) cognitive, iii) motivation, iv) work, v) sleep, vi) appetite, vii) social, viii) activities of daily living, ix) tired/fatigue, x) body pain, and xi) suicidality. Concept saturation, the point at which no new relevant information emerges in later interviews, was achieved for each of the concepts. Based on the qualitative findings, the PRO instrument developed had 15 daily and 20 weekly items. The cognitive interviews confirmed that the instructions, item content, and response scales were understood by the patients. Rigorous qualitative research resulted in the development of a PRO measure for MDD with supported content validity. The MDD PRO can assist in understanding and assessing MDD symptoms from patients' perspectives as well as evaluating treatment benefit of new targeted therapies.

The aim of this technique is to eventually measure weak electron capture branching ratios (ECBRs) and by this to consequently determine GT matrix elements of $ββ$ decaying nuclei. These branching ratios provide important input to the theoretical description of these decays. The feasibility and power of the technique is demonstrated by measuring the ECBR of $^{124}$Cs.

description: Recent studies suggest that concrete creep may be further exacerbated by climate change. However, up to now this effect has not been quantified in literature. The current study addresses this gap and presents a probabilistic approach for quantitatively assessing this effect. For this purpose, five different stochastic creep models (i.e. Model Code 1999, Model Code 2010, B3, B4, and B4s models) are used under considerations of the historical and future climatic conditions in Sweden to assess the long-term creep coefficient and the subsequent stress redistribution of an axially loaded column. While some creep models show similar percentage increases in the long-term creep coefficient in all Swedish counties, other creep models show higher percentage increase values for northern than for southern counties. The highest increase in the end-of-century creep coefficient is found using models B4 and B4s (e.g. over 40% increase is possible for northernmost Sweden, i.e. Norrbotten county, under RCP8.5). Furthermore, the current article also shows that the end-of-century creep coefficient is more sensitive to uncertainties not related to the climate (i.e. parameter and creep modelling uncertainties) than to climate uncertainty.

description: Obesity researchers increasingly use geographic information systems to measure exposure and access in neighborhood food and physical activity environments. This paper proposes a network buffering approach, the “sausage” buffer. This method can be consistently and easily replicated across software versions and platforms, avoiding problems with proprietary systems that use different approaches in creating such buffers. In this paper, we describe how the sausage buffering approach was developed to be repeatable across platforms and places. We also examine how the sausage buffer compares with existing alternatives in terms of buffer size and shape, measurements of the food and physical activity environments, and associations between environmental features and health-related behaviors. We test the proposed buffering approach using data from EAT 2010 (Eating and Activity in Teens), a study examining multi-level factors associated with eating, physical activity, and weight status in adolescents (n = 2,724) in the Minneapolis/St. Paul metropolitan area of Minnesota. Results show that the sausage buffer is comparable in area to the classic ArcView 3.3 network buffer particularly for larger buffer sizes. It obtains similar results to other buffering techniques when measuring variables associated with the food and physical activity environments and when measuring the correlations between such variables and outcomes such as physical activity and food purchases. Findings from various tests in the current study show that researchers can obtain results using sausage buffers that are similar to results they would obtain by using other buffering techniques. However, unlike proprietary buffering techniques, the sausage buffer approach can be replicated across software programs and versions, allowing more independence of research from specific software.

description: Ezatiostat, a glutathione S-transferase P1-1 inhibitor, promotes the maturation of hematopoietic progenitors and induces apoptosis in cancer cells. Ezatiostat was administered to 19 patients with non-deletion(5q) myelodysplastic syndrome (MDS) at one of two doses (2000 mg or 2500 mg/day) in combination with 10 mg of lenalidomide on days 1–21 of a 28-day cycle. No unexpected toxicities occurred and the incidence and severity of adverse events (AEs) were consistent with that expected for each drug alone. The most common non-hematologic AEs related to ezatiostat in combination with lenalidomide were mostly grade 1 and 2 fatigue, anorexia, nausea, diarrhea, and vomiting; hematologic AEs due to lenalidomide were thrombocytopenia, neutropenia, and anemia. One of 4 evaluable patients (25%) in the 2500/10 mg dose group experienced an erythroid hematologic improvement (HI-E) response by 2006 MDS International Working Group (IWG) criteria. Four of 10 evaluable patients (40%) in the 2000 mg/10 mg dose group experienced an HI-E response. Three of 7 (43%) red blood cell (RBC) transfusion-dependent patients became RBC transfusion independent, including one patient for whom prior lenalidomide monotherapy was ineffective. Three of 5 (60%) thrombocytopenic patients had an HI-platelet (HI-P) response. Bilineage HI-E and HI-P responses occurred in 3 of 5 (60%), 1 of 3 with HI-E and HI-N (33%), and 1 of 3 with HI-N and HI-P (33%). One of 3 patients (33%) with pancytopenia experienced a complete trilineage response. All multilineage responses were observed in the 2000/10 mg doses recommended for future studies. The tolerability and activity profile of ezatiostat co-administered with lenalidomide supports the further development of ezatiostat in combination with lenalidomide in MDS and also encourages studies of this combination in other hematologic malignancies where lenalidomide is active.

description: We use a recently introduced combinatorial object, the interval-poset, to describe two bijections on intervals of the Tamari lattice. Both bijections give a combinatorial proof of some previously known results. The first one is an inner bijection between Tamari intervals that exchanges the initial rise and lower contacts statistics. Those were introduced by Bousquet-Mélou, Fusy, and Préville-Ratelle who proved they were symmetrically distributed but had no combinatorial explanation. The second bijection sends a Tamari interval to a closed flow of an ordered forest. These combinatorial objects were studied by Chapoton in the context of the Pre-Lie operad and the connection with the Tamari order was still unclear.

We selected 59 Bp stars, which account for 13.4% of the total number of B type stars in the association. The fraction of peculiar B type stars in the association is found to be twice higher than that of peculiar A type stars. Magnetic field are found in 22 stars, 17 of them are objects with anomalous helium lines. No significant differences are found between the field strengths in the Bp type stars of the association and Bp type field stars. We identified 17 binaries, which make up 20% of the total number of peculiar stars studied which is the standard ratio for CP stars.

description: We consider two-dimensional metals near a Pomeranchuk instability which breaks 90$^\circ$ lattice rotation symmetry. Such metals realize strongly-coupled non-Fermi liquids with critical fluctuations of an Ising-nematic order. At low temperatures, impurity scattering provides the dominant source of momentum relaxation, and hence a non-zero electrical resistivity. We use the memory matrix method to compute the resistivity of this non-Fermi liquid to second order in the impurity potential, without assuming the existence of quasiparticles. Impurity scattering in the $d$-wave channel acts as a random "field" on the Ising-nematic order. We find contributions to the resistivity with a nearly linear temperature dependence, along with more singular terms; the most singular is the random-field contribution which diverges in the limit of zero temperature.

description: As one of IDB’s newest corporate initiatives, the Emerging and Sustainable Cities Initiative (ESCI)ƒ is a technical assistance program that helps intermediate cities in Latin America and the Caribbean identify, prioritize, and structure projects to improve their environmental, urban, and fiscal sustainability, and improve governance. Port of Spain is one of the pilot projects of ESCI. In that context, this Columbia University’s Planning Studio in the Graduate School of Architecture, Planning and Preservation was invited as academic consultants to evaluate the socio-economic viability of some IDB’s ESCI proposals in East Port of Spain, specifically examining: 1) Institutional coordination for improved urban planning; 2) Community engagement in planning; 3) Cultural preservation planning; 4) River revitalization and the creation of a linear park; and 5) An aerial cable car project. We restructured the original five requests presented to us into assessments of three physical interventions complemented by assessments of the broader goals of improved institutional coordination and community engagement, two process-oriented focus areas that ought to support the three urban investment projects. After a semester-long study in spring 2014 and a field work conducted in East Port of Spain in March 2014, we finally offer a reframing of the conceptualization of the three physical interventions and a series of phased proposals. They synergistically support the preservation of cultural heritage, including heritage walks; a series of connected pocket parks lining and permeating the East Dry Rive; and an integrated, multi-modal transit system supported by a data gathering process; along with strategies for enhancing the broader goals of institutional coordination and community engagement. Our goal was to prioritize the residents of East Port of Spain in the development of planning initiatives. In each of the project areas, we are recommending a process rather than specific design recommendations, because we feel it is critical that the community members should be the ones that drive these interventions.

description: Solar wind plasma is supposed to be structured in magnetic flux tubes carried from the solar surface. Tangential velocity discontinuity near the boundaries of individual tubes may result in Kelvin-Helmholtz instability, which may contribute into the solar wind turbulence. While the axial magnetic field may stabilize the instability, a small twist in the magnetic field may allow to sub-Alfvenic motions to be unstable. We aim to study the Kelvin-Helmholtz instability of twisted magnetic flux tube in the solar wind with different configurations of external magnetic field. We use magnetohydrodynamic equations in the cylindrical geometry and derive the dispersion equations governing the dynamics of twisted magnetic flux tube moving along its axis in the cases of untwisted and twisted external fields. Then we solve the dispersion equations analytically and numerically and found thresholds for Kelvin-Helmholtz instability in both cases of external field. Both analytical and numerical solutions show that the Kelvin-Helmholtz instability is suppressed in the twisted tube by external axial magnetic field for sub-Alfvenic motions. However, even small twist in the external magnetic field allows the Kelvin-Helmholtz instability to be developed for any sub-Alfvenic motions. The unstable harmonics correspond to vortices with high azimuthal mode numbers, which are carried by the flow. Twisted magnetic flux tubes can be unstable to Kelvin-Helmholtz instability when they move with small speed relative to main solar wind stream, then the Kelvin-Helmholtz vortices may significantly contribute into the solar wind turbulence.

description: Opioid maintenance treatment (OMT) has a positive impact on substance use and health outcomes among HIV-infected opioid dependent patients. The present study investigates non-medical use of opioids by HIV-infected opioid-dependent individuals treated with buprenorphine or methadone. The MANIF 2000 study is a longitudinal study that enrolled a cohort of 476 HIV-infected opioid-dependent individuals. Data were collected in outpatient hospital services delivering HIV care in France. The sample comprised all patients receiving OMT (either methadone or buprenorphine) who attended at least one follow-up visit with data on adherence to OMT (N = 235 patients, 1056 visits). Non-medical use of opioids during OMT was defined as having reported use of opioids in a non-medical context, and/or the misuse of the prescribed oral OMT by an inappropriate route of administration (injection or sniffing). After adjusting for the non-random assignment of OMT type, a model based on GEE was then used to identify predictors of non-medical use of opioids. Among the 235 patients, 144 (61.3%) and 91 (38.9%) patients were receiving buprenorphine and methadone, respectively, at baseline. Non-medical use of opioids was found in 41.6% of visits for 83% of individual patients. In the multivariate analysis, predictors of non-medical use of opioids were: cocaine, daily cannabis, and benzodiazepine use, experience of opioid withdrawal symptoms, and less time since OMT initiation. Non-medical use of opioids was found to be comparable in OMT patients receiving methadone or buprenorphine. The presence of opioid withdrawal symptoms was a determinant of non-medical use of opioids and may serve as a clinical indicator of inadequate dosage, medication, or type of follow-up. Sustainability and continuity of care with adequate monitoring of withdrawal symptoms and polydrug use may contribute to reduced harms from ongoing non-medical use of opioids.

description: We evaluate semi-inclusive neutral-current quasielastic differential neutrino and antineutrino cross sections within the framework of the relativistic impulse approximation. The results of the relativistic mean field and of the relativistic Green's function models are compared. The sensitivity to the strange-quark content of the nucleon form factor is also discussed. The results of the models are compared with the MiniBooNE experimental data for neutrino scattering. Numerical predictions for flux-averaged antineutrino scattering cross sections are also presented.

description: The Siberian Solar Radio Telescope (SSRT) is a solar-dedicated directly-imaging interferometer observing the Sun at 5.7 GHz. The SSRT operates in the two-dimensional mode since 1996. The imaging principle of the SSRT restricts its opportunities in observations of very bright flare sources, while it is possible to use `dirty' images in studies of low brightness features, which do not overlap with side lobes from bright sources. The interactive CLEAN technique routinely used for the SSRT data provides imaging of active regions but consumes much time and efforts and does not reveal low-brightness features below the CLEAN threshold. The newly developed technique combines the CLEAN routine with the directly imaging capability of the SSRT and provides clean images with an enhanced dynamic range automatically. These elaborations considerably extend the range of tasks, which can be solved with the SSRT. We show some examples of the present opportunities of the SSRT and compare its data with the images produced by the Nobeyama Radioheliograph at 17 GHz as well as observations in different spectral ranges.

description: As a representative of Doctoral candidates and other Early Career Researchers (ECRs) in Europe, Eurodoc advocates for improving the conditions for ECRs as well as for all researchers regarding Academic Freedom. While the conditions of Doctoral Candidates and ECRs vary greatly across Europe, it must be recognised that they are professionals and academia is their workplace – Academic Freedom thus concerns them as well. In the Rome Ministerial Communique, academic freedom is defined as "The freedom of academic staff and students to engage in research, teaching, learning and communication in and with society without interference nor fear of reprisal."  Academic freedom is the freedom of researchers at all levels, and thus it also concerns the academic freedom of doctoral candidates and other early career researchers, just as it concerns the academic freedom of more senior researchers and students. However, from Eurodoc's perspective, there are two aspects of academic freedom that must always be considered, institutional academic freedom and individual academic freedom. These two are not competing from our perspective but are instead closely interlinked. There can be no institutional academic freedom if there is no academic freedom for the individual, and likewise, there can be no proper academic freedom for the individual if there is not also institutional academic freedom. An important part of institutional academic freedom is the independence of academic institutions from governments and others. Here, sufficient funding of academic institutions plays an important role. Academic freedom of individual researchers requires that the researcher does not have to fear reprisal from society, government, academic institutions, other researchers or students. Doctoral candidates and other ECRs have the most precarious positions in academia, and thus they are extremely vulnerable when it comes to reprisals. Yet, as they carry out a significant part of the research, teaching and outreach, there can be no academic freedom if it does not include this group. In this statement, Eurodoc provides a series of recommendations that we advocate must be implemented by governmental and academic institutions to secure academic freedom. While some of these principles concern the academic freedom of doctoral candidates and other early career researchers primarily, most concern the whole of academia. For there can be no academic freedom for any group in academia if there is not both institutional academic freedom and academic freedom for individual researchers in general.

description: Physics and information are intimately connected, and the ultimate information processing devices will be those that harness the principles of quantum mechanics. Many physical systems have been identified as candidates for quantum information processing, but none of them are immune from errors. The challenge remains to find a path from the experiments of today to a reliable and scalable quantum computer. Here, we develop an architecture based on a simple module comprising an optical cavity containing a single negatively-charged nitrogen vacancy centre in diamond. Modules are connected by photons propagating in a fiber-optical network and collectively used to generate a topological cluster state, a robust substrate for quantum information processing. In principle, all processes in the architecture can be deterministic, but current limitations lead to processes that are probabilistic but heralded. We find that the architecture enables large-scale quantum information processing with existing technology.

description: Relatively small, reproductively isolated populations with reduced genetic diversity may have advantages for genomewide association mapping in disease genetics. The Ashkenazi Jewish population represents a unique population for study based on its recent (< 1,000 year) history of a limited number of founders, population bottlenecks and tradition of marriage within the community. We genotyped more than 1,300 Ashkenazi Jewish healthy volunteers from the Hebrew University Genetic Resource with the Illumina HumanOmni1-Quad platform. Comparison of the genotyping data with that of neighboring European and Asian populations enabled the Ashkenazi Jewish-specific component of the variance to be characterized with respect to disease-relevant alleles and pathways. Using clustering, principal components, and pairwise genetic distance as converging approaches, we identified an Ashkenazi Jewish-specific genetic signature that differentiated these subjects from both European and Middle Eastern samples. Most notably, gene ontology analysis of the Ashkenazi Jewish genetic signature revealed an enrichment of genes functioning in transepithelial chloride transport, such as CFTR, and in equilibrioception, potentially shedding light on cystic fibrosis, Usher syndrome and other diseases over-represented in the Ashkenazi Jewish population. Results also impact risk profiles for autoimmune and metabolic disorders in this population. Finally, residual intra-Ashkenazi population structure was minimal, primarily determined by class 1 MHC alleles, and not related to host country of origin. The Ashkenazi Jewish population is of potential utility in disease-mapping studies due to its relative homogeneity and distinct genomic signature. Results suggest that Ashkenazi-associated disease genes may be components of population-specific genomic differences in key functional pathways.

description: Topological states of matter present a wide variety of striking new phenomena. Prominent among these is the fractionalisation of electrons into unusual particles: Majorana fermions [1], Laughlin quasiparticles [2] or magnetic monopoles [3]. Their detection, however, is fundamentally complicated by the lack of any local order, such as, for example, the magnetisation in a ferromagnet. While there are now several instances of candidate topological spin liquids [4], their identification remains challenging [5]. Here, we provide a complete and exact theoretical study of the dynamical structure factor of a two-dimensional quantum spin liquid in gapless and gapped phases. We show that there are direct signatures - qualitative and quantitative - of the Majorana fermions and gauge fluxes emerging in Kitaev's honeycomb model. These include counterintuitive manifestations of quantum number fractionalisation, such as a neutron scattering response with a gap even in the presence of gapless excitations, and a sharp component despite the fractionalisation of electron spin. Our analysis identifies new varieties of the venerable X-ray edge problem and explores connections to the physics of quantum quenches.

The Rebound Effect and Energy Efficiency Policy

description: What do we know about the size of the rebound effect? Should we believe claims that energy
efficiency improvements lead to an increase in energy use? This paper clarifies what the rebound effect is,
and provides a guide for economists and policymakers interested in its magnitude. We describe how some
papers in the literature consider the rebound effect from a costless exogenous increase in energy
efficiency, while others examine the effects of a particular energy efficiency policy—a distinction that
leads to very different welfare and policy implications. We present the most reliable evidence available
quantifying the energy efficiency rebound, and discuss areas where estimation is extraordinarily difficult.
Along these lines, we offer a new way of thinking about the macroeconomic rebound effect. Overall, the
existing research provides little support for the so-called “backfire” hypothesis. Still, much remains to be
understood, particularly relating to induced innovation and productivity growth.

description: The legitimacy of democratic systems requires the protection of minority preferences while ideally treating every voter equally. During the 2006 student elections at Columbia University, we asked voters to rank the importance of different contests and to choose where to cast a single extra "bonus vote," had one been available — a simple version of Storable Votes. We then constructed distributions of intensities and electoral outcomes and estimated the probable impact of the bonus vote through bootstrapping techniques. The bonus vote performs well: when minority preferences are particularly intense, the minority wins at least one contest with 15-30 percent probability; when the minority wins, aggregate welfare increases with 85-95 percent probability. The paper makes two contributions: it tests the performance of storable votes in a setting where preferences were not controlled, and it suggests the use of bootstrapping techniques when appropriate replications of the data cannot be obtained.
