Determinants of the Public's Preference for Social Distance from People with Schizophrenia

Objective: To examine the extent to which the public's desire for social distance from people with schizophrenia is influenced by beliefs about the disorder and stereotypes about those suffering from it. Methods: In spring 2001, we carried out a representative survey of individuals of German nationality aged 18 years and over (n = 5025). Each subject was given a fully structured interview that began with the presentation of a vignette. Results: Both labelling and beliefs about the disorder's causes and prognosis, as well as the perception that those suffering from it are unpredictable and dangerous, had an impact on the public's desire for social distance. However, the latter proved to be more important. As expected, respondents who identified the disorder depicted in the vignette as mental illness, those who blamed the individual for its development, and those who anticipated a poor prognosis expressed a stronger desire for social distance. Endorsing biological factors as a cause was also associated with increased social distance. Conclusions: Our findings have important implications for interventions aimed at reducing stigma and discrimination related to schizophrenia. Targeting the stereotype of unpredictability and dangerousness appears to be particularly important.
Identity-Based Data Aggregation in Wireless Sensor Networks

A data aggregation scheme based on identity is proposed which utilizes the public-key cryptography to realize the negotiation of session keys. The solution uses small- sized seed matrix to generate a mass of public/private key pairs thus consumes little storage space. It realizes the identity authentication independent of the third party and has no use for infrastructure to sustain the key distribution centers. Security of the proposed solution is analyzed and some attacks that can be resisted are listed in this thesis.
Optimism, Distress, Health-Related Quality of Life, and Change in Cancer Antigen 125 Among Patients With Ovarian Cancer Undergoing Chemotherapy

Objective: This study investigated whether situational and dispositional optimism were protective against dimensions of distress and aspects of health-related quality of life (HQoL) in patients with ovarian cancer undergoing chemotherapy. This study also evaluated whether optimism predicted a decrease in cancer antigen (CA) 125 levels during treatment. Methods: Ninety women with epithelial ovarian cancer were assessed at the start and end of chemotherapy. Optimism, distress, and HQoL were measured by self-report; CA 125 levels were gathered from patients' medical charts. Results: Both measures of optimism were inversely associated with baseline anxiety, perceived stress, and depression. In addition, situational optimism was positively associated with baseline social and physical well-being, and dispositional optimism was positively associated with baseline social and functional well-being. However, neither measure of optimism predicted domains of distress or HQoL at the follow-up assessment after controlling for baseline levels. Dispositional optimism predicted CA 125 at the end of treatment after controlling for baseline levels. However, neither situational nor dispositional optimism predicted CA 125 falling to normal levels (≤35 U/mL). Conclusion: Consistent with prior research, optimism was inversely associated with distress and positively associated with HQoL in patients with ovarian cancer undergoing chemotherapy. Higher levels of dispositional optimism at the start of chemotherapy were associated with a greater decline in patients' CA 125 during treatment.

Practical Post- Editing Lexicography with Lexonomy andSketchEngine

In this paper we present an implemented solution for post-editing dictionaries within the Lexonomy dictionary writing system interconnected with the Sketch Engine corpus management system. We follow up on the work on automatic dictionary drafting ("One-Click Dictionary") and assume a dictionary draft to be post-edited, or an existing (edited) dictionary to be extended are in place. We cover focus on features that enable lexicographers to obtain relevant corpus evidence or corpus-driven analysis in a user-friendly way from within the environment of the dictionary writing system and thus speed up their workflow. We exemplify the usage scenario in an ongoing project on Danish-English-Korean bilingual dictionary.
Loss of B7-H1 Expression by Recipient Parenchymal Cells Leads to Expansion of Infiltrating Donor CD8+ T Cells and Persistence of Graft-Versus-Host Disease

Previous experimental studies have shown that acute graft-versus-host disease (GVHD) is associated with two waves of donor CD8+ T cell expansion. In the current studies, we used in vivo bioluminescent imaging, in vivo BrdU labeling, and three different experimental GVHD systems to show that B7-H1 expression by recipient parenchymal cells controls the second wave of alloreactive donor CD8+ T cell expansion and the associated second phase of GVHD. Loss of B7-H1 expression by parenchymal cells during the course of GVHD was associated with persistent proliferation of donor CD8+ T cells in GVHD target tissues and continued tissue injury, whereas persistent expression of B7-H1 expression by parenchymal cells led to reduced proliferation of donor CD8+ T cells in GVHD target tissues and resolution of GVHD. These studies demonstrate that parenchymal cell expression of B7-H1 is required for tolerizing infiltrating T cells and preventing the persistence of GVHD. Our results suggest that therapies designed to preserve or restore expression of B7-H1 expression by parenchymal tissues in the recipient could prevent or ameliorate GVHD in humans.
A prospective evaluation of the symptom-based screening approach to the management of children who are contacts of tuberculosis cases.

BACKGROUND Child tuberculosis contact screening and management can enhance case finding and prevent tuberculosis disease. It is universally recommended but rarely implemented in tuberculosis-endemic settings. The World Health Organization (WHO)-recommended symptom-based screening approach could improve implementation but has not been prospectively evaluated. METHODS We conducted a cohort study of children who were close contacts of pulmonary tuberculosis patients in Indonesia from August 2010 to December 2012. We performed clinical assessment, tuberculin skin test, and chest radiography in all eligible children irrespective of symptoms at baseline. Mycobacterial culture and Xpert MTB/RIF assay were performed on sputum from children with persistent symptoms of suspected tuberculosis. Children were managed according to WHO guidelines and were prospectively followed for 12 months. RESULTS A total of 269 child contacts of 140 index cases were evaluated. At baseline, 21 (8%) children had tuberculosis diagnosed clinically; an additional 102 (38%) had evidence of infection without disease. Of children with any tuberculosis-related symptoms at baseline, 21% had tuberculosis diagnosed compared with none of the asymptomatic children (P < .001). After 12 months of follow-up, none of the 99 eligible young child contacts (<5 years) who received isoniazid preventive therapy (IPT) had developed disease compared with 4 of 149 (2.6%) asymptomatic older children who did not receive IPT. CONCLUSIONS Symptom-based screening is an effective and simple approach to child tuberculosis contact management that can be implemented at the primary healthcare level.
TR-SDTN: Trust based efficient routing in hostile social DTNs

With the development of mobile internet, wireless communications via mobile devices in the form of Delay Tolerant Networks (DTNs), becomes a hot research topic. One critical issue in the DTNs with social characteristics is that there could exist selfish nodes which are unwilling to forward messages from strangers and malicious nodes which intentionally impair normal communication. Although there are a lot research works addressing various issues in the DTNs, most current research works only take communication behavior into account. In view of these defects in the existing works, we propose a novel solution to address the selfish and security issues in the social DTNs. A dynamic trust model is proposed to prevent bad-mouthing and ballot stuffing attacks and the Shannon entropy function is introduced to avoid blackhole and greyhole attacks. The simulation results show that our proposed scheme can significantly improve the performance of the social DTNs.
APPRAISAL KEBERLANJUTAN MULTIDIMENSI PENGGUNAAN LAHAN UNTUK SAWAH DI KARAWANG - JAWA BARAT

Indonesian national food sovereignty is very dependent on the supply of rice from paddy fields in Java Island. Various factors influence the farmer’s decision to continue using his farm. This study aims to analyze the sustainable use of paddy field, determinant factors and strategies for improving sustainability. The study was conducted in Karawang Regency, one of the centers of rice production in West Java. The methodology used is a multi-dimensional scaling (MDS) using 43 attributes of 5 dimensions (ecological, social, economical, technological and legal and institutional dimension). Against the sensitive attribute analysis resulting from MDS, a prospective analysis was conducted to determine the key factors of sustainability. Priority policies for improving sustainability are developed based on the location of the key factors in the prospective diagram. The research results showed that the land utilization for paddy field in Karawang is actually less sustainable. Increasing the sustainability can be done through intervention and improving performance, preferably on sensitive attributes resulting from leverage analysis, covering 16 attributes. Priority policies is directed in the 5 key factors resulting from prospective analysis. Policies suggested are the tightening of new permits for building, strict implementation of the official spatial land use planning and delineation of agricultural land for sustainable food crops, counseling the community, revitalizing the role of BULOG, provision of subsidies as well as capital assistance to farmers.
Identification of patients with acute myeloblastic leukemia who benefit from the addition of gemtuzumab ozogamicin: results of the MRC AML15 trial.

PURPOSE Antibody-directed chemotherapy for acute myeloid leukemia (AML) may permit more treatment to be administered without escalating toxicity. Gemtuzumab ozogamicin (GO) is an immunoconjugate between CD33 and calicheamicin that is internalized when binding to the epitope. We previously established that it is feasible to combine GO with conventional chemotherapy. We now report a large randomized trial testing the addition of GO to induction and/or consolidation chemotherapy in untreated younger patients. PATIENTS AND METHODS In this open-label trial, 1,113 patients, predominantly younger than age 60 years, were randomly assigned to receive a single dose of GO (3 mg/m(2)) on day 1 of induction course 1 with one of the following three induction schedules: daunorubicin and cytarabine; cytarabine, daunorubicin, and etoposide; or fludarabine, cytarabine, granulocyte colony-stimulating factor, and idarubicin. In remission, 948 patients were randomly assigned to GO in course 3 in combination with amsacrine, cytarabine, and etoposide or high-dose cytarabine. The primary end points were response rate and survival. RESULTS The addition of GO was well tolerated with no significant increase in toxicity. There was no overall difference in response or survival in either induction of consolidation. However, a predefined analysis by cytogenetics showed highly significant interaction with induction GO (P = .001), with significant survival benefit for patients with favorable cytogenetics, no benefit for patients with poor-risk disease, and a trend for benefit in intermediate-risk patients. An internally validated prognostic index identified approximately 70% of patients with a predicted benefit of 10% in 5-year survival. CONCLUSION A substantial proportion of younger patients with AML have improved survival with the addition of GO to induction chemotherapy with little additional toxicity.
Fair Non-Orthogonal Multiple Access for Visible Light Communication Downlinks

This letter investigates a downlink power control strategy for visible light communication (VLC) systems with non-orthogonal multiple access. Our goal is to maximize sum throughput of the multiuser VLC systems subject to both user fairness and unique intensity constraints for optical modulations. Though the original problem is nonconvex, we first transform it into an equivalent convex one by introducing auxiliary variables and applying variable transformation. Then, we present an optimal power control algorithm with low complexity. Numerical results show large rate gains compared to the conventional OFDM scheme.
Pulmonary Hypertension in Chronic Renal Failure Patients

BACKGROUND/AIMS Pulmonary hypertension (PHT) has been reported to be high among end-stage renal disease (ESRD) patients. This study evaluated PHT in ESRD patients and the role of arteriovenous fistula (AVF), thromboxane B(2) (TXB(2)) and pro-BNP in this complication. METHODS 45 ESRD patients on regular hemodialysis (HD) (group 1) and 31 ESRD patients on conservative treatment (group 2) underwent clinical and biochemical testing. Pulmonary artery pressure (PAP) was evaluated using Doppler echocardiography. Cardiac assessment by echocardiography and AVF flow measurement by Doppler ultrasound were done. Levels of TXB(2) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in plasma were determined. RESULTS PHT was found in 44.4% in group 1 and in 32.3% in group 2. Comparing the two groups shows a significant difference with regard to PAP, proBNP, and TXB(2). Patients with PHT have a significantly higher AVF blood flow, proBNP, and TXB(2). In patients with PHT, 76.7% have left ventricular diastolic dysfunction (LVDD). PAP correlates with AVF flow, proBNP, and TXB(2). CONCLUSIONS Results show a high prevalence of PHT among patients with ESRD on chronic HD or on conservative treatment. PHT in such patients is related to AVF flow, TXB(2) and NT-proBNP level and LVDD. AVF flow is an important correctable cause of PHT.
Impaired Work Productivity After Aneurysmal Subarachnoid Hemorrhage

ABSTRACT Background: Aneurysmal subarachnoid hemorrhage (aSAH) is a sudden debilitating condition affecting individuals during the most productive times of their lives. Treatment advances have reduced mortality rates but increased the number of survivors facing deficits in physical and neuropsychological function. Objective: This study examined associations between neuropsychological function and work productivity after aSAH. Methods: Fifty-two patients with aSAH, employed before hemorrhage, were recruited from an ongoing National Institutes of Health study. Work Limitations Questionnaire (WLQ), neuropsychological tests (executive function, psychomotor speed, attention and mental flexibility, memory), and Patient Assessment of Own Function were completed at 3 and 12 months after aSAH. Results: Subjects in this analysis reported some level of difficulty in work productivity at 3 and 12 months (35% and 30%, respectively) after hemorrhage. Lower WLQ scores in time management and mental/interpersonal subscales were associated with poorer performance in psychomotor function (r = .5, p = .04 and r = .42, p = .09). Poorer mental flexibility and working memory correlated with time management difficulty at 3 months (r = −.4, p = .09 and r = .54, p = .02). Patients performing poorly on story recall tests were more likely to report difficulty with job physical performance (r = −.42, p = .09) and completing work effectively (r = .61, p = .009). Poorer working memory performance was associated with lower scores on mental/interpersonal WLQ subscales (r = .45, p = .05) and overall health-related work productivity loss (r = .47, p = .04). WLQ areas also correlated with participants’ perception of their neuropsychological function after aSAH. Conclusions: These results suggest that neuropsychological deficits impact work quality after hemorrhage and provide strong impetus for future studies so that domain-specific interventions can be implemented to improve outcomes that affect quality of life including work productivity.
Coding techniques for the noisy magnetic recording channel: a state-of-the-art report

Coding techniques for improving the reliability of information storage on noisy magnetic recording channels are considered. It is assumed that the Lorentzian channel model applies and that the retrieved signal is perturbed with additive white Gaussian noise. The immunity against additive noise of state-of-the-art codes such as DC-free, runlength-limited, and trellis codes are assessed. >
Discovery of bridgmanite, the most abundant mineral in Earth, in a shocked meteorite

Meteorites exposed to high pressures and temperatures during impact-induced shock often contain minerals whose occurrence and stability normally confine them to the deeper portions of Earth’s mantle. One exception has been MgSiO3 in the perovskite structure, which is the most abundant solid phase in Earth. Here we report the discovery of this important phase as a mineral in the Tenham L6 chondrite and approved by the International Mineralogical Association (specimen IMA 2014-017). MgSiO3-perovskite is now called bridgmanite. The associated phase assemblage constrains peak shock conditions to ~ 24 gigapascals and 2300 kelvin. The discovery concludes a half century of efforts to find, identify, and characterize a natural specimen of this important mineral. X-ray analysis identifies magnesium silicate perovskite, now known as bridgmanite, in a heavily shocked meteorite. [Also see Perspective by Sharp] A mineral name for mantle perovskite A rock from outer space finally puts a name to Earth's most abundant mineral, frequently referred to as perovskite. Mineral names are only bestowed on specimens that are found in nature and characterized. Tschauner et al. isolate a magnesium silicate in the perovskite structure, now called bridgmanite, in the Tenham L6 chondrite meteorite (see the Perspective by Sharp). Bridgmanite formed in this meteorite during a high-pressure and -temperature shock event. Other minerals associated with bridgmanite allow the pressure-temperature conditions to be narrowly bound, giving insight into the shock process. The long-sought-after specimen finally puts to rest a confusing nomenclature of this dense deep mantle silicate. Science, this issue p. 1100; see also p. 1057
A Simple Numerical Method for Pricing an American Put Option

We present a simple numerical method to find the optimal exercise boundary in an American put option. We formulate an intermediate function with the fixed free boundary that has Lipschitz character near optimal exercise boundary. Employing it, we can easily determine the optimal exercise boundary by solving a quadratic equation in time-recursive way. We also present several numerical results which illustrate a comparison to other methods.
Microbial contamination of cell phones of nursing department students in Technical Institute of Baqubah, Iraq

This study was aimed to investigate microbiological colonization of cell phones used by nursing students of Baqubah Technical Institute, from June to August 2018. In 150 randomly collected cell phones, 133 bacterial and 74 fungal species were isolated using sterile swabs from cell phones surface. The microbe were identified using conventional methods, bacterial species isolated were: Staphylococcus aureus (48%), Staphylococcus epidermidis (25.2), Pseudomonas aeruginosa (14.1), Bacillus subtilis (7%), Escherichia coli (2.3), Streptococcus viridians (2%) and Proteus spp. (1.2%) whereas, the fungal species isolated were Cladosporium spp. (36.1%), Alternaria spp. (17%), Penicillium (9%), Aspergillus fumigates (6.3%), and Aspergillus niger (32%). The bacterial isolates were tested by antibiotic disks diffusion method. High percentage of bacterial isolates was found resistance to erythromycin, cefoxitin, ciprofloxacin and clindamycin. Several S. aureus and S. epidermides isolates were resistant to erythromycin and cefoxitin. The Proteus spp. and E. coli were found highly sensitive to ampicilin, amikacin, cefepime, cefroxain and imipenem. However, the P. aeruginoae spp. showed two different antibiotics sensitivity profiles for the similar antibiotics. This study confirmed that the students cell phones were contaminated with several pathogenic bacterial and fungal species thus might act as an important source of cross-transmission of human and antibiotics resistant. Key words: Cell phones, microbial contamination, nursing students, fungal species, Staphylococcus aureus.
An intercellular regenerative calcium wave in porcine coronary artery endothelial cells in primary culture

1 A regenerative calcium wave is an increase in cytosolic free calcium concentration ([Ca2+]i) which extends beyond the stimulated cells without decrement of amplitude, kinetics of [Ca2+]i increase and speed of propagation. 2 The aim of the present study was to test the hypothesis that such a wave could be evoked by bradykinin stimulation and by scraping cultured endothelial cells from porcine coronary arteries. 3 Calcium imaging was performed using the calcium‐sensitive dye fura‐2. A wound or a delivery of bradykinin to two to three cells on growing clusters of ≈300 cells caused an increase in [Ca2+]i which was propagated throughout the cluster in a regenerative manner over distances up to 400 μm. This wave spread through gap junctions since it was inhibited by the cell uncoupler palmitoleic acid. 4 The same experiments performed in confluent cultures caused a rise in [Ca2+]i which failed to propagate in a regenerative way. The wave propagation probably failed because the confluent cells were less dye coupled than the growing cells. This was confirmed by immunohistology which detected a dramatic decrease in the number of connexin 40 gap junctions in the confluent cultures. 5 The regenerative propagation of the wave was blocked by inhibitors of calcium‐induced calcium release (CICR) and phospholipase C (PLC), and by suppression of extracellular calcium, but not by clamping the membrane potential with high‐potassium solution. 6 We conclude that regenerative intercellular calcium waves exist in cultured islets but not in confluent cultures of endothelial cells. An increase in [Ca2+]i is not sufficient to trigger a regenerative propagation. The PLC pathway, CICR and extracellular calcium are all necessary for a fully regenerated propagation.
