MUSICFX: an arbiter of group preferences for computer supported collaborative workouts

Environmental factors affecting shared spaces are typically designed to appeal to the broadest potential audiences they will serve, while ignoring the preferences of the actual inhabitants found in the environment at any given time. Examples of such factors include the lighting, temperature and décor in the common areas of an office building. MUSICFX is a group preference arbitration system that allows the members of a fitness center to influence, but not directly control, one of these shared factors: the selection of music in the fitness center. The system includes a database of member preferences, a badge reader to track who is in the fitness center, and a group preference arbitration algorithm that sorts the 91 genres of music (available via satellite) according to the preferences of the current group of members. MUSICFX has been in daily operation at the fitness center in the Northbrook office of Andersen Consulting since November 1997, and currently has over 800 members enrolled in the system. This video illustrates the impact of MUSICFX in a series of vignettes and describes how the system allocates influence among the inhabitants of the fitness center environment. Further details on the system can be found in our CSCW ’98 paper.
Local Feature Selection for Generation of Ensembles in Text Clustering

In the context of text clustering, global feature selection tries to identify a single subset of features which are relevant to all clusters. However, the clustering process might be improved by considering different subsets of features for locally describing each cluster. In experiments with local feature selection, it was observed that the resulting partitions were unstable but there were cohesive groups that did not occur in all executions. Based on this result, local feature selection was proposed to generate partitions to be used in ensemble clustering. New experiments were performed to evaluate the generated ensembles and a gain in precision was observed.
LTL-UDE @ EmpiriST 2015: Tokenization and PoS Tagging of Social Media Text

We present a detailed description of our submission to the EmpiriST shared task 2015 for tokenization and part-of-speech tagging of German social media text. As relatively little training data is provided, neither tokenization nor PoS tagging can be learned from the data alone. For tok-enization, our system uses regular expressions for general cases and word lists for exceptions. For PoS tagging, adding unsupervised knowledge beyond the available training data is the most important factor for reaching acceptable tagging accuracy. A learning curve experiment shows furthermore that more in-domain training data is very likely to further increase accuracy.
The impact of smartphones on social behaviour and relationships

Previous research suggests that people use phones mostly as a means to enhance interpersonal closeness. The current study examined the impact of smartphones on social behaviour and relationships, investigating smartphone use, present absence, phone etiquette, face-to-face communication and computer-mediated communication. The study used internet testing with a quasi-experimental and correlational design. A snowball sample of 279 participants aged between 18 and 77 years completed self-report questionnaires: Smartphone Problematic Use Questionnaire; Face-to-face or Computer-mediated communication Questionnaire; Present Absence Scale; and Cellular Phone Etiquette Questionnaire. Results showed that smartphone use and preference for computer-mediated communication were predictors of present absence. Additionally, age was positively related to phone etiquette and preference for face-to-face communication and negatively related to smartphone use, present absence, and computer-mediated communication. Differences highlighted, included higher levels of phone use and present absence, and lower levels of phone etiquette among smartphone users, compared to standard mobile phone users. In conclusion, smartphones undoubtedly have both pervasive and negative influences over users and it would be valuable if future research focussed on the possible reasons for this.
Critical role of RecA and RecF proteins in strand break rejoining and maintenance of fidelity of rejoining following γ-radiation-induced damage to pMTa4 DNA in E. coli

Purpose: This study was undertaken to understand the roles of RecA and RecF proteins in strand break rejoining and maintenance of fidelity of the process following exposure of E. coli to γ-radiation in vivo. Materials and methods: A plasmid DNA construct, pMTa4, was transformed into isogenic repair proficient (wild) and deficient (recF and recA) E. coli strains and γ-irradiated up to 30 Gy in vivo. The plasmid DNA was isolated under repair non-permissive (R−)and permissive (R+) conditions and analyzed by gel electrophoresis for the yields of single strand breaks (SSB) and double strand breaks (DSB) and their repair. The clonogenic survival of the E. coli was also recorded. The effects of γ-irradiation on recA reconstituted with cell free extract of wild strain or ultra-violet (UV)-irradiation were also monitored. Results: None of the strains used in this investigation showed effects of radiation-induced oxidative base damage. The dose dependent increase in SSB and DSB on pMTa4 in wild and recF mutants in R− condition were abolished upon repair incubation. The recA mutant exhibited a disturbed yield of SSB and DSB along with formation of γ-radiation-induced ‘ladder’. The ‘ladder’ was not observed after repair incubation, UV-irradiation or γ-irradiation in presence of cell-free extract of wild strain. The survival of recA mutants was seriously compromised. Conclusions: Wild, recF and recA strains of E. coli could repair γ-irradiation-induced oxidative damage to base or nucleotide (NT) in vivo. In absence of either RecA or RecF proteins, efficiency of rejoining of strand went down; RecA proteins seemed more critical than RecF in this. High fidelity or correct rejoining of strand breaks, on the other hand, seemed to require simultaneous presence of both RecA and RecF proteins.
C. elegans bicd-1, homolog of the Drosophila dynein accessory factor Bicaudal D, regulates the branching of PVD sensory neuron dendrites

The establishment of cell type-specific dendritic arborization patterns is a key phase in the assembly of neuronal circuitry that facilitates the integration and processing of synaptic and sensory input. Although studies in Drosophila and vertebrate systems have identified a variety of factors that regulate dendrite branch formation, the molecular mechanisms that control this process remain poorly defined. Here, we introduce the use of the Caenorhabditis elegans PVD neurons, a pair of putative nociceptors that elaborate complex dendritic arbors, as a tractable model for conducting high-throughput RNAi screens aimed at identifying key regulators of dendritic branch formation. By carrying out two separate RNAi screens, a small-scale candidate-based screen and a large-scale screen of the ∼3000 genes on chromosome IV, we retrieved 11 genes that either promote or suppress the formation of PVD-associated dendrites. We present a detailed functional characterization of one of the genes, bicd-1, which encodes a microtubule-associated protein previously shown to modulate the transport of mRNAs and organelles in a variety of organisms. Specifically, we describe a novel role for bicd-1 in regulating dendrite branch formation and show that bicd-1 is likely to be expressed, and primarily required, in PVD neurons to control dendritic branching. We also present evidence that bicd-1 operates in a conserved pathway with dhc-1 and unc-116, components of the dynein minus-end-directed and kinesin-1 plus-end-directed microtubule-based motor complexes, respectively, and interacts genetically with the repulsive guidance receptor unc-5.
LICENSE TO COMMENT

Commentators have become a widely used news source and popular work force in many news organizations. Previous research, however, has done little to help describe and discuss the background for the rise, reach and relevance of commentators in a specific journalistic context—even though many commentators have originally worked as journalists, depend on journalistic work as daily points of reference and appear in journalistic settings, whenever they comment on politics. This neglect is addressed in this article that takes the biography and bibliography of Walter Lippmann as a starting point for analyzing the popularization of political commentators. Building on Lippmann's life and the books, columns and other texts he produced during his career, this article presents a new analytical framework that might help explain the practical and principal potentials—and problems—those past and present commentators represent in a journalistic context.
Thermokarst rates intensify due to climate change and forest fragmentation in an Alaskan boreal forest lowland

Lowland boreal forest ecosystems in Alaska are dominated by wetlands comprised of a complex mosaic of fens, collapse‐scar bogs, low shrub/scrub, and forests growing on elevated ice‐rich permafrost soils. Thermokarst has affected the lowlands of the Tanana Flats in central Alaska for centuries, as thawing permafrost collapses forests that transition to wetlands. Located within the discontinuous permafrost zone, this region has significantly warmed over the past half‐century, and much of these carbon‐rich permafrost soils are now within ~0.5 °C of thawing. Increased permafrost thaw in lowland boreal forests in response to warming may have consequences for the climate system. This study evaluates the trajectories and potential drivers of 60 years of forest change in a landscape subjected to permafrost thaw in unburned dominant forest types (paper birch and black spruce) associated with location on elevated permafrost plateau and across multiple time periods (1949, 1978, 1986, 1998, and 2009) using historical and contemporary aerial and satellite images for change detection. We developed (i) a deterministic statistical model to evaluate the potential climatic controls on forest change using gradient boosting and regression tree analysis, and (ii) a 30 × 30 m land cover map of the Tanana Flats to estimate the potential landscape‐level losses of forest area due to thermokarst from 1949 to 2009. Over the 60‐year period, we observed a nonlinear loss of birch forests and a relatively continuous gain of spruce forest associated with thermokarst and forest succession, while gradient boosting/regression tree models identify precipitation and forest fragmentation as the primary factors controlling birch and spruce forest change, respectively. Between 1950 and 2009, landscape‐level analysis estimates a transition of ~15 km² or ~7% of birch forests to wetlands, where the greatest change followed warm periods. This work highlights that the vulnerability and resilience of lowland ice‐rich permafrost ecosystems to climate changes depend on forest type.
Wnt signaling promoter hypermethylation distinguishes lung primary adenocarcinomas from colorectal metastasis to the lung

Promoter hypermethylation is responsible for gene inactivation during carcinogenesis. It has been proposed that there is some degree of specificity in the set of genes that become altered by this mechanism in distinct tumor types. To understand whether promoter hypermethylation may differentiate the site of origin, 49 lung adenocarcinomas from 31 lung primaries and 18 metastases from colorectal primaries, respectively, were tested for the presence of this alteration in the APC, CDH1, DAPK, GSTP1, MLH1, MGMT, P14, P16, RARβ2, RASSF1, sFRP1 and WIF‐1 genes. A distinct profile was apparent for the 2 groups of lung tumors and the frequencies of promoter hypermethylation at sFRP1 and WIF‐1, 2 genes involved in Wnt signaling, and at CDH1 were significantly higher in colorectal metastases than in lung primaries, whereas methylation of the APC promoter was significantly more common in lung primary adenocarcinomas. Some tumors showed concomitant APC, sFRP1 and WIF‐1 gene inactivation, indicating that multiple DNA methylation events must have occurred to definitively down‐regulate the signaling through Wnt. However, promoter hypermethylation at the APC and CDH1 genes tended to be mutually exclusive (Fisher's exact test, p = 0.006), suggesting a similar role in carcinogenesis. In conclusion, we propose that inactivation by promoter hypermethylation at the APC, CDH1, sFRP1 and WIF‐1 genes may contribute to the discrimination of lung primary adenocarcinomas from colorectal metastasis to the lung, and report the simultaneous presence of methylation at the promoters of multiple genes involved in the Wnt signaling. This may have biological consequences for carcinogenesis. © 2006 Wiley‐Liss, Inc.
Over diagnosis of chronic obstructive pulmonary disease in an underserved patient population

Introduction While cross-national studies have documented rates of chronic obstructive pulmonary disease (COPD) misdiagnosis among patients in primary care, US studies are scarce. Studies investigating diagnosis among uninsured patients are lacking. Objective The purpose of this study is to identify patients who are over diagnosed and thus, mistreated, for COPD in a federally qualified health center. Methods A descriptive study was conducted for a retrospective cohort from February 2011 to June 2012. Spirometry was performed by trained personnel following American Thoracic Society recommendations. Patients were referred for spirometry to confirm previous COPD diagnosis or to assess uncontrolled COPD symptoms. Airway obstruction was defined as a forced expiratory volume in the first second of expiration (FEV1) to forced vital capacity ratio less than 0.7. Reversibility was defined as a postbronchodilator increase in FEV1 greater than 200 mL and greater than 12%. Results Eighty patients treated for a previous diagnosis of COPD (n = 72) or on anticholinergic inhalers (n = 8) with no COPD diagnosis were evaluated. The average age was 52.9 years; 71% were uninsured. Only 17.5% (14/80) of patients reported previous spirometry. Spirometry revealed that 42.5% had no obstruction, 22.5% had reversible obstruction, and 35% had non-reversible obstruction. Conclusion Symptoms and smoking history are insufficient to diagnose COPD. Prevalence of COPD over diagnosis among uninsured patient populations may be higher than previously reported. Confirming previous COPD diagnosis with spirometry is essential to avoid unnecessary and potentially harmful treatment.
Ju l 2 00 1 THE REST-FRAME OPTICAL PROPERTIES OF z ≃ 3 GALAXIES 1

We present the results of a near-infrared imaging survey of z ∼ 3 Lyman Break Galaxies (LBGs). The survey covers a total of 30 arcmin2 and includes 118 photometrically selected LBGs with Ks band measurements, 63 of which also have J band measurements, and 81 of which have spectroscopic redshifts. Using the distribution of optical R magnitudes from previous work and R− Ks colors for this sub-sample, we compute the rest-frame optical luminosity function of LBGs. This luminosity function is described by an analytic Schechter fit with a very steep faint end slope of α = −1.85 ± 0.15, and it strikingly exceeds locally determined optical luminosity functions at brighter magnitudes, where it is fairly well constrained. The V -band luminosity density of only the observed bright end of the z ∼ 3 LBG luminosity function already approaches that of all stars in the local universe. For the 81 galaxies with measured redshifts, we investigate the range of LBG stellar populations implied by the photometry which generally spans the range 900–5500 Å in the rest-frame. The parameters under consideration are the star-formation rate as a function of time, the time since the onset of star-formation, and the degree of reddening and extinction by dust. While there are only weak constraints on the parameters for most of the individual galaxies, there are strong trends in the sample as a whole. With a wider wavelength baseline than most previous studies at similar redshifts, we confirm the trend that intrinsically more luminous galaxies are dustier. We also find that there is a strong correlation between extinction and the age of the star-formation episode, in Based on data obtained at the W.M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California, and NASA, and was made possible by the generous financial support of the W.M. Keck Foundation.
Single Cell Impedance Measurements using Microfabricated Electrodes and Labview Graphical Programming

This Master's Thesis project consists of the research, design, and fabrication of a system that could perform broadband impedance measurements (1kHz-20Mhz) of single cells using National Instruments Labview data acquisition and programming in coordination with a single cell capture device. Presented first is the background information on cells and their electrical properties, along with background in micro-total-analysis systems as well as impedance spectroscopy. Experimental Methods are then discussed for the electrode design, cellular modeling in COMSOL, fabrication methods, and Labview 8.0 Setup and programming. Measurements were performed using the single-cell capture device on saline, yeast cells, and a polysterene bead. Analysis of the impedance data showed a clear visual and statistically significant difference between live yeast, the bead, and saline. A comparison of live yeast cells to nutrient-starved yeast cells was also performed and a distinct difference in spectra was observed. v ACKNOWLEDGMENTS First and foremost I'd like to thank my professors and advisors Dr. Dave Clague and Dr. Robert Szlavik for giving me the chance to work on a project with such exciting implications, and also supporting and encouraging me over the last several years.

British Psychoanalytic Attitudes Towards Homosexuality

SUMMARY This paper describes the attitudes of British Psychoanalysis toward homosexuality, starting from the time of Ernest Jones to the present day. It traces the development of psychoanalytic theory from its total pathologising of all expressions of homosexuality towards a more questioning and non-pathologising formulation. The article illustrates how changes in psychoanalytic theory and practice both mirror and are influenced by the changing legal and societal status of homosexuality in the United Kingdom. Although openly gay and lesbian candidates are beginning to be accepted into psychoanalytic training, the continued existence of antihomosexual prejudice and bias suggest an ongoing need for continuing education and concern.
Claves interoceptivas y exteroceptivas en la tolerancia al efecto atáxico del etanol en ratas

evidence of interoceptive pharmacologic cues and of exteroceptive cues, which are associated with the effect of the drug. The former could overshadow the latter. The aim of the present investigation was to contribute experimental data about the interaction that occurs between these two kinds of cues. For this purpose, a set of interoceptive and exteroceptive cues was presented as conditioned stimulus, together with an unconditioned stimulus that corresponded to the ataxic effects of ethanol. The results showed that the interoceptive cues were associated with the ataxic effect of ethanol, and they produced a tolerance response of the same intensity as the exteroceptive cues.
Numerical Analysis of Flow around Rectangular Cylinders with Various Side Ratios

Three-dimensional numerical analysis of the flow around rectangular cylinders with various side ratios, D/H, from 0.2 to 2.0, was carried out for Reynolds number of 10³ by using a multi-directional finite difference method on a regular-arranged multi-grid. The predicted results are in good agreement with the experimental data. It is found that fluid dynamic characteristics of rectangular cylinders alternate between the high-pressure mode and the low-pressure mode of the base pressure for D/H=0.2-0.6. We show that this phenomenon is induced by the change of the flow pattern around rectangular cylinders.
Using subcategorization knowledge to improve case prediction for translation to German

This paper demonstrates the need and impact of subcategorization information for SMT. We combine (i) features on sourceside syntactic subcategorization and (ii) an external knowledge base with quantitative, dependency-based information about target-side subcategorization frames. A manual evaluation of an English-toGerman translation task shows that the subcategorization information has a positive impact on translation quality through better prediction of case.
Using an Extended Theory of Planned Behavior to Study Nurses' Adoption of Healthcare Information Systems in Nova Scotia

This study used the theory of planned behavior TPB, which was extended to include relevant constructs such as computer self-efficacy, anxiety and habit, to investigate registered nurses' RNs' adoption of healthcare information systems HIS in Nova Scotia, Canada. An analysis of data collected from 197 RNs in a cross-sectional survey showed that their attitudes towards HIS were positively impacted by computer self-efficacy and computer anxiety lack thereof. RNs' attitudes toward HIS and facilitating organizational conditions significantly influenced intentions to use HIS at work. Contrary to prediction, subjective norm did not influence RNs' intentions to use HIS in the research setting. Computer habit mattered for RNs' acceptance of HIS. Information from the study benefits the management of RNs' HIS use in Nova Scotia, in particular, and comparable parts of Canada and the world.
