A Comparison of Treatment Outcomes Among Chronically Homelessness Adults Receiving Comprehensive Housing and Health Care Services Versus Usual Local Care

Service use and 2-year treatment outcomes were compared between chronically homelessness clients receiving comprehensive housing and healthcare services through the federal Collaborative Initiative on Chronic Homelessness (CICH) program (n = 281) a sample of similarly chronically homeless individuals receiving usual care (n = 104) in the same 5 communities. CICH clients were housed an average of 23 of 90 days (52%) more than comparison group subjects averaging over all assessments over a 2-year follow-up period. CICH clients were significantly more likely to report having a usual mental health/substance abuse treater (55% vs. 23%) or a primary case manager (26% vs. 9%) and to receive community case management visits (64% vs. 14%). They reported receiving more outpatient visits for medical (2.3 vs. 1.7), mental health (2.8 vs. 1.0), substance abuse treatment (6.4 vs. 3.6), and all healthcare services (11.6 vs. 6.1) than comparison subjects. Total quarterly healthcare costs were significantly higher for CICH clients than comparison subjects ($4,544 vs. $3,326) due to increased use of outpatient mental health and substance abuse services. Although CICH clients were also more likely to receive public assistance income (80% vs. 75%), and to have a mental health/substance provider at all, they expressed slightly less satisfaction with their primary mental health/substance abuse provider (satisfaction score of 5.0 vs. 5.4). No significant differences were found between the groups on measures of substance use, community adjustment, or health status. These findings suggest that access to a well funded, comprehensive array of permanent housing, intensive case management, and healthcare services is associated with improved housing outcomes, but not substance use, health status or community adjustment outcomes, among chronically homeless adults.
Quantifying Device Degradation in Live Power Converters Using SSTDR Assisted Impedance Matrix

A noninterfering measurement technique designed around spread spectrum time domain reflectometry (SSTDR) has been proposed in this paper to identify the level of aging associated with power semiconductor switches inside a live converter circuit. Power MOSFETs are one of the most age-sensitive components in power converter circuits, and this paper demonstrates how SSTDR can be used to determine the characteristic degradation of the switching MOSFETs used in various power converters. An SSTDR technique was applied to determine the aging in power MOSFETs, while they remained energized in live circuits. In addition, SSTDR was applied to various test nodes of an H-bridge ac-ac converter, and multiple impedance matrices were created based on the measured reflections. An error minimization technique has been developed to locate and determine the origin and amount of aging in this circuit, and this technique provides key information about the level of aging associated to the components of interest. By conducting component level failure analysis, the overall reliability of an H-bridge ac-ac converter has been derived and incorporated in this paper.
IDEAL spiral CSI for dynamic metabolic MR imaging of hyperpolarized [1-13C]pyruvate.

Metabolic imaging with hyperpolarized [1-(13)C]pyruvate offers the unique opportunity for a minimally invasive detection of cellular metabolism. Efficient and robust acquisition and reconstruction techniques are required for capturing the wealth of information present for the limited duration of the hyperpolarized state (~1 min). In this study, the Dixon/IDEAL type of water-fat separation is expanded toward spectroscopic imaging of [1-(13) C]pyruvate and its down-stream metabolites. For this purpose, the spectral-spatial encoding is based on single-shot spiral image encoding and echo-time shifting in between excitations for the chemical-shift encoding. In addition, also a free-induction decay spectrum is acquired and the obtained chemical-shift prior knowledge is efficiently used in the reconstruction. The spectral-spatial reconstruction problem is found to efficiently separate into a chemical-shift inversion followed by a spatial reconstruction. The method is successfully demonstrated for dynamic, multislice [1-(13)C]pyruvate metabolic MR imaging in phantom and in vivo rat experiments.
Illumination invariant face recognition based on neural network ensemble

An illumination invariant face recognition method based on neural network ensemble architecture is proposed. Given a face image with an arbitrary illumination direction, it can complete recognition in a uniform way with high performance without knowing or estimating the illumination direction. Experimental result shows that the recognition ratio of the ensemble architecture is higher than the conventional approach that uses a single neural network to recognize faces of a specific illumination direction.
Nitroglycerin infusion after percutaneous coronary intervention does not influence short- and long-term outcome--a prospective NAPI (Nitroglycerin Administration after Percutaneous Intervention) study.

BACKGROUND
Although the benefit of nitroglycerin infusion in patients after elective coronary angioplasty has not been established, this regimen is routinely used in some centres.


AIM
The Nitroglycerin Administration after Percutaneous Intervention (NAPI) study tested the efficacy of routine nitroglycerin infusion on the 1st day after percutaneous coronary intervention (PCI) in a double-blind randomised single-centre clinical trial.


METHODS
We randomly assigned 200 patients scheduled for elective PCI to treatment with nitroglycerin (100 patients, age 58+/-6 years, infusion up to 100 microg/min) or placebo (100 patients, age 57+/-5 years, p=NS, NaCl 0.9%) for 12 hours after PCI. Patients with acute myocardial infarction, haemodynamic instability during PCI and known intolerance to nitrates were excluded. Patients who were randomised to the placebo group had the possibility to receive nitroglycerin infusion according to the attending physician's decision. Clinical endpoints (cardiac death, myocardial infarction, postprocedural chest pain, unstable angina and repeated PCI) were assessed in hospital and out of hospital with follow-up extended to 24 months.


RESULTS
There were no differences during in-hospital stay between those receiving nitroglycerin and receiving placebo, regarding mortality (0 vs. 0%, NS), myocardial infarction (0 vs. 2%, NS), postprocedural chest pain (10 vs. 8%, NS) or repeated PCI (0 vs. 2%, NS). Similarly, 24-month follow-up also revealed no significant differences between those receiving nitroglycerin and placebo (mortality: 0 vs. 0%, NS; myocardial infarction: 4 vs. 4%, NS; repeated PCI: 10 vs. 8%, NS or CABG: 0 vs. 0%, NS).


CONCLUSIONS
Routine use of intravenous nitroglycerin after elective PCI has no influence on in-hospital and long-term outcome, including cardiac death, myocardial infarction, postprocedural chest pain, unstable angina and repeated PCI.

We prove strong normalization of tq-reduction for all standard versions of sequent calculus for classical and intuitionistic (second and rst order) logic and give a perspicuous argument for the completeness of the focusing restriction on sequent derivations.
Learning by Doing with Asymmetric Information : Evidence from Prosper

This paper examines the nature of information asymmetry in online peer-to-peer (P2P) lending markets. These markets use the Internet to match individual borrowers and lenders of consumer loans without financial institutions as intermediaries. Like other anonymous interactions, P2P lending may face additional information asymmetry as compared to offline because P2P lenders have less access to “hard” information such as borrower credit history, income, or employment. However, the shortage of “hard” information could be mitigated by “soft” information via online social networks. We examine this tradeoff using data from all requested and funded loans between June 1, 2006 and July 31, 2008 on Prosper.com. We have three main findings. First, Prosper lenders understand the ordinal difference across credit grades but the incomplete disclosure of a borrower’s credit history leads to additional adverse selection relative to traditional markets. Second, some social networks help to mitigate information asymmetry and others do not, depending on the institutional incentives. Third, lenders, especially those who joined Prosper early, did not fully understand the market risk. We estimate, on average, lenders would have expected an annualized internal rate of return of -0.62% to -1.38% on a dollar invested if they had correctly understood the risk distribution of Prosper loans. However, lender learning is effective in reducing the risk of funded loans over time. As a result, the market has excluded more and more sub-prime borrowers and evolved towards the population served by traditional credit markets.
Performance analysis: experimental computer science at its best

In the third installment of this symposium, which originally appeared in the Communication the ACM, we go back to 1981. More than 30 years ago, I called on ACM members to employ more experimental methods and avoid confusing hacking (tinkering) with true science. Joining a long tradition of ACM Presidents speaking up about computing as science.
Compassion: a scoping review of the healthcare literature.

BACKGROUND
Recent concerns about suboptimal patient care and a lack of compassion have prompted policymakers to question the preparedness of clinicians for the challenging environment in which they practice. Compassionate care is expected by patients and is a professional obligation of clinicians; however, little is known about the state of research on clinical compassion. The purpose of this scoping review was to map the literature on compassion in clinical healthcare.


METHODS
Searches of eight electronic databases and the grey literature were conducted to identify empirical studies published over the last 25 years. Eligible studies explored perceptions or interventions of compassionate care in clinical populations, healthcare professionals, and healthcare students. Following the title and abstract review, two reviewers independently screened full-texts articles, and extracted study data. A narrative approach to synthesizing and mapping the literature was used.


RESULTS AND DISCUSSION
Of 36,637 records, 648 studies were retrieved and 44 studies were included in the review. Less than one third of studies included patients. Six themes emerged from studies that explored perceptions of compassionate care: nature of compassion, development of compassion, interpersonal factors related to compassion, action and practical compassion, barriers and enablers of compassion, and outcomes of compassion. Intervention studies included two compassionate care trials with patients and eight educational programs that aimed to improve compassionate care in clinicians and students.


CONCLUSIONS
This review identifies the limited empirical understanding of compassion in healthcare, highlighting the lack of patient and family voices in compassion research. A deeper understanding of the key behaviors and attitudes that lead to improved patient-reported outcomes through compassionate care is necessary.
Subjective and objective measurement of human accommodative amplitude.

PURPOSE
To assess objective and subjective methods to measure accommodation in a young human population.


SETTING
Research laboratory, University of Houston, College of Optometry, Houston, Texas, USA.


METHODS
Accommodation was measured in the right eye of 15 young subjects (9 women and 6 men) whose ages ranged from 23 to 28 years and 1 36-year-old subject. The mean age of all subjects was 26 years. Accommodation was stimulated and measured with 4 techniques. Two subjective measures (focometer and minus-lens procedures) were used. Accommodation was also stimulated with minus-lens-induced blur and with pilocarpine 6% and measured objectively with a Hartinger coincidence refractometer.


RESULTS
Accommodative amplitudes measured with the 2 subjective methods agreed with each other but differed from the objectively measured amplitudes. Objectively measured accommodative amplitudes were similar in all subjects, with a mean of about 7.0 diopters. Accommodation stimulated with pilocarpine reached a maximum 33 minutes after administration. Individuals with light irides showed a stronger accommodative response to pilocarpine than subjects with dark irides.


CONCLUSIONS
Subjective measures of accommodation tend to overestimate true accommodative amplitude. Methods exist to measure accommodation objectively. These include stimulating accommodation with trial lenses or pilocarpine 6% and measuring the accommodative response with an objective optometer such as a Hartinger coincidence refractometer. Objective measures of accommodation should be used to determine whether accommodation can be restored in presbyopes.
Paving the way for CRM success: The mediating role of knowledge management and organizational commitment

Customer relationship management (CRM) has become one of the most influential technologies in the world, and companies are increasingly implementing it to create value. However, despite significant investment in CRM technology infrastructure, empirical research offers inconsistent support for its positive impact on performance. This study develops and tests a research model analyzing the process through which CRM technology infrastructure translates into organizational performance, drawing on the resource-based view (RBV) and the knowledge-based view (KBV) of the firm. Based on an international sample of 125 hotels, the results suggest that organizational commitment and knowledge management fully mediate this process. 2014 Elsevier B.V. All rights reserved.
GPS-less low-cost outdoor localization for very small devices

Instrumenting the physical world through large networks of wireless sensor nodes, particularly for applications like marine biology, requires that these nodes be very small, light, un-tethered and unobtrusive, imposing substantial restrictions on the amount of additional hardware that can be placed at each node. Practical considerations such as the small size, form factor, cost and power constraints of nodes preclude the use of GPS(Global Positioning System) for all nodes in these networks. The problem of localization, i.e., determining where a given node is physically located in a network is a challenging one, and yet extremely crucial for many applications of very large device networks. It needs to be solved in the absence of GPS on all the nodes in outdoor environments. In this paper, we propose a simple connectivity-metric based method for localization in outdoor environments that makes use of the inherent radiofrequency(RF) communications capabilities of these devices. A fixed number of reference points in the network transmit periodic beacon signals. Nodes use a simple connectivity metric to infer proximity to a given subset of these reference points and then localize themselves to the centroid of the latter. The accuracy of localization is then dependent on the separation distance between two adjacent reference points and the transmission range of these reference points. Initial experimental results show that the accuracy for 90% of our data points is within one-third of the separation distance. Keywords—localization, radio, wireless, GPS-less, connectivity, sensor networks.
A Stochastic Model for Order Book Dynamics

We propose a stochastic model for the continuous-time dynamics of a limit order book. The model strikes a balance between two desirable features: it captures key empirical properties of order book dynamics and its analytical tractability allows for fast computation of various quantities of interest without resorting to simulation. We describe a simple parameter estimation procedure based on high-frequency observations of the order book and illustrate the results on data from the Tokyo stock exchange. Using Laplace transform methods, we are able to efficiently compute probabilities of various events, conditional on the state of the order book: an increase in the mid-price, execution of an order at the bid before the ask quote moves, and execution of both a buy and a sell order at the best quotes before the price moves. Comparison with highfrequency data shows that our model can capture accurately the short term dynamics of the limit order book.

Car-driver cooperation in future vehicles

The two main research branches in intelligent vehicles field are Advanced Driver Assistance Systems (ADAS) [1] and autonomous driving [2]. ADAS generally work on predefined enviroment and limited scenarios such as highway driving, low speed driving, night driving etc. In such situations this systems have sufficiently high performance and the main features that allow their large diffusion and that have enabled commercialization in this years are the low cost, the small size and the easy integration into the vehicle. Autonomous vehicle, on the other hand, should be ready to work over all-scenarios, all-terrain and all-wheather conditions, but nowadays autonomous vehicle are used in protected and structured enviroments or military applications [3], [4]. Generally many differences between ADAS and autonomous vehicles, both hardware and software features, are related on cost and integration: ADAS are embedded into vehicles and might be low cost; on the other hand usually are not heavy limitations on cost and integration related to autonomous vehicles. Obviosly, the main difference is the presence/absence of the driver. Otherwise, most of the undelying ideas are shared, such as perception, planning, actuation needed in this kind of systems.
Translation drafting by professional translators and by translation students

Em experimentos conduzidos entre 2000 e 2001, oito tradutores traduziram, cada um, quatro textos diferentes, dois do dinamarquês para o inglês e dois do inglês para o dinamarquês. Quatro deles eram alunos de tradução do último ano (tradutores semiprofissionais) do Departamento de Inglês da Copenhagen Business School (CBS), e quatro eram tradutores profissionais (expertos) com pelo menos dois anos de experiência em tradução após a graduação. Os textos-fonte foram exibidos no Translog, que também gravou detalhes do processo de digitação dos textos-alvo pelos tradutores. Em Jakobsen (2003), traduzido neste volume, buscou-se determinar o efeito da verbalização concomitante do pensamento em voz alta (do inglês, think aloud protocol, ou TAP) na velocidade da tradução, na revisão e na segmentação. Todas as medições se basearam em tarefas completas de tradução. No presente artigo, procedeu-se a uma nova divisão dos dados: subdividiram-se as tarefas de tradução (32 ao todo) em três fases (orientação, redação e revisão) e fizeram-se cálculos para cada uma dessas fases (i.e., 96 atividades). Dessa forma, foi possível determinar diferenças (e semelhanças) entre indivíduos e grupos em cada uma das três fases de produção. Na análise apresentada em Jakobsen (2003), a velocidade total de tradução dos tradutores profissionais, ao contrário do que se esperava, não se mostrou significativamente mais rápida do que a do grupo de semiprofissionais. A análise aqui relatada ajuda a explicar
Development and external validation of nomograms predicting distant metastases and overall survival after neoadjuvant chemotherapy and surgery for patients with nonmetastatic osteosarcoma: A multi‐institutional study

BACKGROUND
In this era of individualized cancer treatment, data that could be applied to predicting the survival of patients with osteosarcoma are still limited because of the rarity of the disease and the difficulty in accumulating a sufficient number of patients. Therefore, a multi-institutional collaboration was implemented to develop and externally validate nomograms that would predict metastasis-free survival (MFS) and overall survival (OAS) for patients with nonmetastatic osteosarcoma.


METHODS
This study retrospectively examined 1070 patients treated with neoadjuvant chemotherapy and surgery for nonmetastatic osteosarcoma. Data from Japanese patients (n = 557) were used to develop multivariate nomograms based on Cox regression. Six clinical and pathologic variables were built into nomograms estimating the probability of MFS and OAS 3 and 5 years after diagnosis. The model was internally validated for discrimination and calibration with bootstrap resampling and was externally validated with an independent patient cohort from Korea (n = 513).


RESULTS
A patient's age, tumor site, and histologic response were found to have a stronger influence on MFS and OAS in the model than sex, tumor size, or pathologic fracture. The nomograms and calibration plots based on these results well predicted the probability of MFS (concordance index, 0.631) and OAS (concordance index, 0.679). The concordance indices for external validation were 0.682 for MFS and 0.665 for OAS.


CONCLUSIONS
The nomograms were externally validated and verified to be useful for the prediction of MFS and OAS and for the assessment of the postoperative prognosis. They can be used for counseling patients and for establishing appropriate surveillance strategies after surgery.
A robotic finger mechanism for robust industrial applications

Purpose – The purpose of this paper is to present the design and analysis of a robotic finger mechanism for robust industrial applications. Design/methodology/approach – The resultant design is a compact rigid link finger, which is adaptive to different shapes and sizes providing necessary grasping features. A number of such fingers can be assembled to function as a special purpose end effector. Findings – The mechanism removes a number of significant problems usually experienced with tendon-based designs. The finger actuation mechanism forms a compact and positive drive unit within the end effector’s body using solid mechanical linkages and integrated actuators. Practical implications – The paper discusses the design issues associated with a limited number of actuators to operate in a constrained environment and presents various considerations necessary to ensure safe and reliable operations. Originality/value – The design is original in existence and developed for special purpose handling applications that offers a strong and reliable system where space and safety is of prime concern.
