Least-squares Polynomial Lters for Ill-conditioned Linear Systems

An important problem which arises in several applications is to nd the solution of an ill-conditioned Symmetric Semi-Positive Deenite linear system whose right-hand side is perturbed by noise. In this situation, it is desirable for the solution to be accurate in the directions of eigenvectors associated with large eigenvalues, and to have small components in the space associated with smallest eigenvalues. A method is presented to satisfy these requirements, which is based on constructing a polynomial lter using least-squares techniques.
WebTraff: a GUI for Web proxy cache workload modeling and analysis

The paper describes an interactive graphical user interface (GUI) that can be used for the modeling and analysis of Web proxy workloads. The WebTraff GUI has three main components. First, the WebTraff tool provides a visual front-end to ProWGen, a Web proxy workload generation tool developed in prior work (see Busari, M. and Williamson, C., Computer Networks, vol.38, no.6, p.779-94, 2002), which can be used for generating synthetic Web proxy workloads of arbitrary length, with user-specified statistical properties. Second, the WebTraff GUI provides tools for the analysis of Web proxy workload characteristics, including document size distribution, document popularity profile, and temporal locality properties. Third, the GUI provides a front-end to a simple Web proxy cache simulation program, which can be used in studies of Web proxy cache performance and cache filter effects.
Does Turnover Intention Matter? Evaluating the Usefulness of Turnover Intention Rate as a Predictor of Actual Turnover Rate

Turnover research has traditionally examined intention to turnover rather than actual turnover. Such studies assume that leave intent serves equally well as both a proxy for and predictor of employees’ actual turnover behavior. The purpose of this study is to provide an agency-level evaluation of the usefulness of turnover intention as a reliable proxy and predictor of actual turnover across 180 U.S. federal agencies, using hierarchical (stepwise) multiple regression. Our findings suggest that, at the organizational level, turnover intention and actual turnover are distinct concepts, predicted by different sets of variables. Based on these findings, we conclude that public managers tasked with retention might have better foresight concentrating on their agencies’ unique demographic characteristics and specific management practices, rather than on their employees’ self-reported aggregated turnover intention rate.
Supervision and monitoring

§ 115.241 Screening for risk of victimization and abusiveness. (a) All residents shall be assessed during an intake screening and upon transfer to another facility for their risk of being sexually abused by other residents or sexually abusive toward other residents. (b) Intake screening shall ordinarily take place within 72 hours of arrival at the facility. (c) Such assessments shall be conducted using an objective screening instrument. (d) The intake screening shall consider, at a minimum, the following criteria to assess residents for risk of sexual victimization: (1) Whether the resident has a mental, physical, or developmental disability; (2) The age of the resident; (3) The physical build of the resident; (4) Whether the resident has previously been incarcerated; (5) Whether the resident’s criminal history is exclusively nonviolent; (6) Whether the resident has prior convictions for sex offenses against an adult or child; (7) Whether the resident is or is perceived to be gay, lesbian, bisexual, transgender, intersex, or gender nonconforming; (8) Whether the resident has previously experienced sexual victimization; and (9) The resident’s own perception of vulnerability.
Human motion imitation for humanoid by Recurrent Neural Network

In this paper, it is investigated how a humanoid can be controlled from a human motion in a tele-operation system. The proposed method is based on Recurrent Neural Networks (RNN) to extract features in nonlinear sequential data. Therefore, our proposed RNN model can extract the features of the relation between a human and a robot, and generate motion of a robot using these features. Also, the generated robot motion is modified to maintain balance with stable contact on the ground. The effectiveness of the proposed new mapping algorithm is verified through simulations.
QUESC: an instrument for assessing the service quality of sport centers in Korea.

This research study developed an instrument that would serve as an important part of a quality improvement program for sport centers. The developed instrument may be used on an ongoing basis to identify the kinds of services customers want, the level of service they desire, and specific areas requiring managerial attention. An analysis of survey data from sport center users in Korea shows 33 important customer needs that can be classified into 11 distinct dimensions. Using the QUESC instrument, this study found that the performance of Korean sport centers is lagging behind user expectations. Although data was obtained from Korean sport centers, the approach of this Study and most of its findings may be applied to the North American sport center market as well.
The Underprepared College Student: How Non-Cognitive Factors Influence Academic Preparedness

The purpose of this exploratory phenomenological study was to explore the influence of non-cognitive factors on academic preparedness. Interviews were conducted with a sample of underprepared college students concerning several areas of non-cognitive factors: early educational factors; personal factors; affective factors; and, non-cognitive skill factors. The students' attitudes and experiences revealed several themes concerning the influence of non-cognitive factors and academic preparedness. Findings related to textual categories indicated personal factors such as the students' experiences of coming from a broken home and family strife, or personal issues such as alcohol abuse and bad decision-making skills were possible reasons for their negative educational experiences. Additionally, their narratives about their youth suggested a lack of parental involvement in their early educational experiences. Structural theme findings suggested the malleability of non-cognitive skill factors such as their creative and practical skills, as well as affective factors, were a positive influence on the students’ motivation to continue their degree aspirations. Key findings included a creative
Study of Excess Heat Capacity and Suppressed Kapitza Conductance in TES Devices

A number of groups have produced TES bolometers and other devices using dielectric membranes for thermal isolation in which excess heat capacity is reported. We have fabricated a series of TES devices using large area membranes and narrow legs for thermal isolation to study the scaling of intrinsic parameters like the heat capacity of the membrane. The devices are arranged on a single chip to ensure similarity of devices parameters (i.e., film thicknesses) and processing history. Measurements (non-multiplexed) of the current-voltage characteristic and complex impedance are made using a well-characterized, highly uniform, multichannel SQUID setup. We have developed model for non-ideal transition edge sensor performance that enables extraction of heat capacities and thermal conductances identified in the models. We report on the magnitude of excess heat capacity in the dielectric membrane and thermal conductance of the metal-to-dielectric interface in each of the designs.
The Social Construction of Entrepreneurship: Narrative and Dramatic Processes in the Coproduction of Organizations and Identities

A social dimension to business development and inertia is currently acknowledged in several accounts of learning, business models, vision building, and innovation, and through more general concepts of networking, social capital, and embeddedness. Here a constructionist perspective is developed to improve our understanding of the interactions between entrepreneurs and stakeholders in all of these areas. This identifies narrative and dramatic processes that describe how notions of individual and collective identity and organization are coproduced over time. A framework is created to show how selective and emotional processes that produce storylines, emplotment, and narrative structure support sense making and action making.
The Emergence of Prosocial Behavior: Why Do Infants and Toddlers Help, Comfort, and Share?

The early development of prosocial behavior has become a major topic in developmental psychology. Although findings on the early presence of prosocial tendencies in infants and toddlers have received much attention and the examination of their subsequent developmental pathways has fostered ample research, little is known about the mechanisms and motives that bring about the first emergence of these prosocial actions. In this article, I introduce and review theoretical approaches, then evaluate them in light of recent findings. I conclude that the forms of early prosocial behavior are related to different social-cognitive mechanisms and underpinned by various motives.
Phosphonium alkyl PEG sulfate ionic liquids as coating materials for activation of Burkholderia cepacia lipase

Lipases are among the most widely used enzymes applicable for various substrates; however, the slow reactions or poor enantioselective reactions are sometimes obtained. To develop ionic liquid type activating agents for lipase, four types of phosphonium cetyl(PEG)10 sulfate ionic liquids have been synthesized and used as coating materials of Burkholderia cepacia lipase (Lipase PS) through the lyophilization process. Tributyl ([2‐methoxy]ethoxymethyl)phosphonium cetyl(PEG)10 sulfate ([P444MEM][C16(PEG)10SO4]) (PL1) worked best among them, and PL1‐coated lipase PS displayed high reactivity in transesterification of broad types of secondary alcohols using vinyl acetate as an acylating reagent with perfect enantioselectivity (E > 200). The substrate preference of PL1‐PS differs from that of commercial lipase PS or [bdmim] [C16(PEG)10SO4]‐coated lipase (IL1‐PS); PL1‐PS displayed excellent enantioselectivity in the reaction of 2‐chloro‐1‐phenylethanol with E > 200, though insufficient E values were recorded for lipase PS (E = 12) and IL1‐PS (E = 123) for this alcohol. PL1‐PS also showed perfect enantioselectivity (E > 200) for the reaction of 1‐(pyridin‐2‐yl)ethanol, while IL1‐PS showed E = 130 for this compound. We further succeeded in demonstrating the recyclable use of PL1‐PS five times in tributyl(3‐methoxypropyl)phosphonium bis(trifluoromethylsulfonyl)amide ([P444PM][Tf2N]) as a solvent. Since PL1‐PS is easily applicable to 10–20 gram‐scaled reactions, it is expected that the IL‐coated enzyme might be useful for practical preparation of a wide variety of chiral secondary alcohols.
What’s Fat Got to Do with It? On Different Kinds of Losses and Gains in the Analytic Relationship

This article uses the blunt term fat to shake up readers’ attitudes and to challenge them to think about how their own prejudices about fatness affect their treatment of fat patients. The clinical work presented is a reconsideration of Bion’s work, with a relational emphasis on projective identification and container/contained. It follows what happens in a treatment where both analyst and patient are unable to examine dysregulating feelings related to the size of their bodies and what their bodies conveyed regarding feeding, overeating, and being fat. This article traces the analyst’s own growth and learning, starting from a position of sharing the patient’s fat hatred, through her own integration of previously dissociated fat hatred, the consequent emergence of an impasse and what she learned in its working through. It highlights how the impact of the patient helped her to change, reciprocally enabling the patient’s growth.
Conceptual and Methodological Challenges in Producing Research Syntheses for Decision-and Policy-Making: An Illustrative Case in Primary Healthcare

This article presents and discusses five challenges encountered in conducting a knowledge synthesis on primary healthcare, commissioned by the Canadian Health Services Research Foundation. These challenges are (1) conceptualizing, defining and operationalizing complex interventions; (2) integrating quantitative and qualitative studies and assessing strength of evidence; (3) incorporating expert opinions and decision-makers’ viewpoints; (4) producing timely results; and (5) presenting the results in a concise yet understandable form. We also propose methods and operational tools to deal with these issues, particularly regarding integration of qualitative and quantitative evidence and incorporation of expert opinions into syntheses. The major challenge of the synthesis was to provide pertinent and useful information for decision- and policy-makers, while maintaining an acceptable level of scientific rigour. This approach seems promising for knowledge syntheses, which sustain a deliberative process that leads to more enlightened decision and policy-making.
Citizen Science Opportunities in Volunteer-Based Online Experiments

Online experimentation with volunteers could be described as a form of citizen science in which participants take part in behavioral studies without financial compensation. However, while citizen science projects aim to improve scientific understanding, volunteer-based online experiment platforms currently provide minimal possibilities for research involvement and learning. The goal of this paper is to uncover opportunities for expanding participant involvement and learning in the research process. Analyzing comments from 8,288 volunteers who took part in four online experiments on LabintheWild, we identified six themes that reveal needs and opportunities for closer interaction between researchers and participants. Our findings demonstrate opportunities for research involvement, such as engaging participants in refining experiment implementations, and learning opportunities, such as providing participants with possibilities to learn about research aims. We translate these findings into ideas for the design of future volunteer-based online experiment platforms that are more mutually beneficial to citizen scientists and researchers.
A Surround Video Capture and Presentation System for Preservation of Eye-Gaze in Teleconferencing Applications

We propose a new video conferencing system that uses an array of cameras to capture a remote user and then show the video of that person on a spherical display. This telepresence system has two key advantages: (i) it can capture a near-correct image for any potential observer viewing direction because the cameras surround the user horizontally; and (ii) with view-dependent graphical representation on the spherical display, it is possible to tell where the remote user is looking from any viewpoint, whereas flat displays are visible only from the front. As a result, the display can more faithfully represent the gaze of the remote user. We evaluate this system by measuring the ability of observers to accurately judge which targets the actor is gazing at in two experiments. Results from the first experiment demonstrate the effectiveness of the camera array and spherical display system, in that it allows observers at multiple observing positions to accurately tell at which targets the remote user is looking. The second experiment further compared a spherical display with a planar display and provided detailed reasons for the improvement of our system in conveying gaze. We found two linear models for predicting the distortion introduced by misalignment of capturing cameras and the observer's viewing angles in video conferencing systems. Those models might be able to enable a correction for this distortion in future display configurations.
Mobile Sensing on GSM Channel Utilization at Metropolitan Scales

Access to accurate GSM power spectrograms in large cities can be of great interest to mobile network operators. Acquiring such information in urban settings is very challenging mainly due to the large area and high dynamics of environments. In this paper, we propose a novel scheme to tackle the large-scale mobile sensing problem. We first utilize an open source GSM project to collect RSSI values of all 194 GSM channels. Combining with moving vehicles, the sensing coverage can be enhanced. We leverage a commercial smartphone to perceive the moving direction and speed of the vehicle. With the motion information, the corresponding GSM power measures can be bound with the trajectory of the vehicle, forming the GSM power spectrograms. We have implemented the design of our system and conducted extensive on-road experiments. The results show the efficacy of the system.
Las Vegas The Impact of the Patient-Centered Medical Home on Health Disparities in Adults : A Systematic Review of the Evidence

Introduction: The objective of this study was to review the empirical evidence on PatientCentered Medical Home (PCMH) impact on health disparities in adults. Methods: We searched PubMed, Scopus, and Google Scholar to identify studies on PCMH/health homes and health disparities published in English between January 1, 2009 and December 31, 2014. Articles met inclusion criteria if they investigated at least one component of PCMH or health homes in vulnerable populations, defined by PROGRESS-PLUS criteria, and reported differences in one of five clinical quality measures. Results: 964 articles were identified through database searching and subsequent snowballing. 60 articles underwent full text screening. Further review eliminated 56 studies. In the final 4 studies, PCMH interventions showed small improvements in health disparities. Discussion: The PCMH has been suggested as a model for improving health disparities. Given rapid implementation in underserved settings, stakeholders should better understand the impact of the PCMH on health disparities.
Enriching Automated Essay Scoring Using Discourse Marking

Electronic Essay Rater (e-rater) is a prototype automated essay scoring system built at Educational Testing Service (ETS) that uses discourse marking, in addition to syntactic information and topical content vector analyses to automatically assign essay scores. This paper gives a general description ore-rater as a whole, but its emphasis is on the importance of discourse marking and argument partitioning for annotating the argument structure of an essay. We show comparisons between two content vector analysis programs used to predict s c o r e s . EsscQ/'Content and ArgContent. EsscnContent assigns scores to essays by using a standard cosine correlation that treats the essay like a "'bag of words. " in that it does not consider word order. Ark, Content employs a novel content vector analysis approach for score assignment based on the individual arguments in an essay. The average agreement between ArgContent scores and human rater scores is 82%. as compared to 69% agreement between EssavContent and the human raters. These results suggest that discourse marking enriches e-rater's scoring capability. When e-rater uses its whole set of predictive features, agreement with human rater scores ranges from 87°,/o 94% across the 15 sets of essa5 responses used in this study
Subring Homomorphic Encryption Seiko

In this paper, we construct subring homomorphic encryption scheme that is a homomorphic encryption scheme built on the decomposition ring, which is a subring of cyclotomic ring. In the scheme, each plaintext slot contains an integer in Zpl , rather than an element of GF(p) as in conventional homomorphic encryption schemes on cyclotomic rings. Our benchmark results indicate that the subring homomorphic encryption scheme is several times faster than HElib for mod-p integer plaintexts, due to its high parallelism of mod-p integer slot structure. We believe in that such plaintext structure composed of mod-p integer slots will be more natural, easy to handle, and significantly more efficient for many applications such as outsourced data mining, than conventional GF(p) slots.
Antipsychotics and the risk of sudden cardiac death.

BACKGROUND Case reports link antipsychotic drugs with sudden cardiac deaths, which is consistent with dose-related electrophysiologic effects. Because this association has not been confirmed in controlled studies, we conducted a retrospective cohort study in Tennessee Medicaid enrollees, which included many antipsychotic users; there were also computer files describing medication use and comorbidity. The study was conducted before the introduction of risperidone and, thus, did not include the newer atypical agents. METHODS The cohort included 481,744 persons with 1,282,996 person-years of follow-up. This included 26,749 person-years for current moderate-dose antipsychotic use (>100-mg thioridazine equivalents), 31,864 person-years for current low-dose antipsychotic use, 37,881 person-years for use in the past year only, and 1 186,501 person-years for no use. The cohort had 1487 confirmed sudden cardiac deaths; from these, we calculated multivariate rate ratios adjusted for potential confounding factors. RESULTS When current moderate-dose antipsychotic use was compared with nonuse, the multivariate rate ratio was 2.39 (95% confidence interval, 1.77-3.22; P<.001). This was greater than that for current low-dose (rate ratio, 1.30; 95% confidence interval, 0.98-1.72; P=.003) and former (rate ratio, 1.20; 95% confidence interval, 0.91-1.58; P<.001) use. Among cohort members with severe cardiovascular disease, current moderate-dose users had a 3.53-fold (95% confidence interval, 1.66-7.51) increased rate relative to comparable nonusers ( P<.001), resulting in 367 additional deaths per 10,000 person-years of follow-up. CONCLUSIONS Patients prescribed moderate doses of antipsychotics had large relative and absolute increases in the risk of sudden cardiac death. Although the study data cannot demonstrate causality, they suggest that the potential adverse cardiac effects of antipsychotics should be considered in clinical practice, particularly for patients with cardiovascular disease.
Multi‐Ethnic Parties in Bosnia‐Herzegovina: Naša Stranka and the Paradoxes of Postethnic Politics

To what extent is political mobilisation across ethnic boundaries possible in states with highly ethnicised state structures? This article explores the opportunities and obstacles that activists in Bosnia-Herzegovina meet when they seek to develop integrative discourses as a basis for political action. The first part of the article focuses on the role of multi-ethnic parties in deeply divided societies. The second part develops alternative ideas on the obstacles facing multi-ethnic parties in Bosnia, focusing on the case of Nasa Stranka, a political party that was established by civil society actors. There are two conclusions to be drawn. First, despite the centrifugal nationalisms that seem to dominate the top political level, there are civil society actors in Bosnia who engage in integrative political mobilisation. Second, these actors face difficulties that go beyond the often-cited problem of the tendency of the constitutional state structure to reify ethnic identities.
