Podcasting Lectures: The Next Silver Bullet?
Authors: Williams Brett , Bearman Margaret
Published: December 2018

This paper will be the first in a series outlining the contemporary use of educational technology in paramedic higher education.

Objectives

This paper describes a pilot study, which examines the student use of podcasting service within a Bachelor of Emergency Health (BEH) degree. The aim of this study is to report student usage patterns of the podcasting service as well as any perceived advantages or disadvantages to podcasting.

Methods

Second and third year undergraduate paramedic students (n=67) were surveyed with respect to their use of the podcasting service in 2006. An annual audit of students’ learning needs was taken from 2006-2008 with respect to relevant general student profile information.

Results

Almost two-thirds n=42 (62.7%) of the students did not download the Podcast lecture material. Of those that did, twenty students (29.9%) used Podcasts for reviewing lecture content; only two (3%) as a substitute to attending the lecture. Students described positive benefits as well as difficulties with the technology; seventeen (25.4%) reported revising concepts which they had not understood. The audit demonstrated that in Semester 1, 2008, 83% of students owned iPods or equivalent.

Conclusion

While only a minority of BEH students listened to the podcast lectures, those that did reported use for revision of theoretical concepts and revision for examinations. Podcasting appears to have significant potential for mobile learning (m-learning) allowing some students the capacity to utilise their study time more effectively. Podcasting may well prove useful for particular students, and should be given some qualified support.
Multidisciplinary Practice in Action: The Rural Paramedic – It's not Only Lights and Sirens
Authors: Mulholland Peter , O'Meara Peter , Walker Judith , Stirling Christine , Tourle Vianne
Published: December 2018

Objectives

This paper examines the Tasmanian portion of a four state study commissioned by the Australian Council of Ambulance Authorities in order to examine the expanded scope of practice for Australian rural paramedics. The objectives of this paper were to describe the expanded role for the rural paramedic on the East Coast of Tasmania and determine what factors facilitate this role.

Methods

This study uses qualitative methods. Three sources of data were used for this study: a) semi-structured interviews with key informants; b) direct observation of key processes and events, and c) review of documents describing the paramedic role and required organisational and educational support. The semi-structured interviews included questions relating to the role of the paramedic, involvement with other health disciplines, and interactions within the general community.

Findings

The study revealed how paramedics on the East Coast of Tasmania have developed a multidisciplinary and multifaceted approach to health care. Emergency care does not end at the hospital doorstep and involves co-operation between paramedics and hospital staff in ongoing care. Doctors and other health professionals who have previously been involved in after hours call outs, training of volunteer ambulance personnel are now free from these additional and often time-consuming tasks. Paramedics have been welcomed as part of the health care team in the area and have been responsible for development of effective working relationships with hospital staff and doctors, volunteers and community members. An important part of these relationships is the health education provided by paramedics.

Conclusion

Emergency response in rural areas is only a small part of paramedic practice. This study has identified elements of rural paramedic practice that highlight the importance of a multidisciplinary and community based response to patient care in rural areas namely community involvement, organisational support, professional support, and appropriate education and training. Much of these are rooted in a footing of informality. The move from informality to a more formal framework will perhaps enable rural paramedic practice to emerge as a discipline in its own right, as an integral part of a rural multidisciplinary health care team.
The Effect of Provider Level Triage in a Military Treatment Facility Emergency Department
Authors: Barbee George , Berry-Cabán Cristóbal , Daymude Marc , Oliver Jeffrey , Gay Steven
Published: December 2018

Introduction

Studies show that patients who spend more than 2 hours in the emergency department (ED) report more dissatisfaction with their visits. To remedy this situation, several EDs have implemented programs that insert a medical provider into triage. The objective of this study was to determine whether a Physician Assistant (PA) and Combat Medic performing triage care during peak hours could increase patient throughput.

Methods

This study is a comparative analysis. We implemented an Emergency Department Provider Level Triage Team (PLTT) that consisted of 1 Emergency Medicine Physician Assistant and 1 Combat Medic to intervene in patient care in the ED at Womack Army Medical Center (WAMC), Fort Bragg, North Carolina, USA. Three days of 12 hours shifts were selected during the peak hours of the ED and compared to the same period on days that did not have the intervention. Only patients categorized with an Emergency Severity Index of 2 or 3 were selected and compared. No additional medical, nursing and medic staff were used. This study was approved by the WAMC Institutional Review Board.

Results

In total, there were 241 cases during the trial period and 231 controls. Median times were significantly reduced (p=<0.001) during the intervention period. Times to analgesia (97.4 min v 171.1 min, p=0.03), time to laboratory results (103.8 min v 143.9 min, p=0.01), radiology (136.3 min v 181.6 min, p=<0.001), and to disposition (317.4 min v 334.6 min, p=0.05) were all decreased. Nearly 90% of patients in the intervention group said that their experience with the intervention was very good or outstanding.

Conclusion

The implementation of the PLTT model in our ED was associated with reduced time to healthcare provider assessment, decreased overall ED length of stay, and improved patient satisfaction.
Transformasi Agropolitan TV dari Penyiaran Pemerintah menjadi LPP Lokal (The Transformation of Agropolitan TV from Government Broadcasting to Public Broadcasting)
Authors: Putra I. Gusti Ngurah
Published: December 2018

Disahkannya Undang-Undang Penyiaran tahun 2002 telah mengubah sistem penyiaran Indonesia dari sistem penyiaran yang berpusat pada negara ke sistem penyiaran yang lebih demokratis. Lembaga penyiaran pemerintah harus diubah menjadi lembaga penyiaran publik yang memberi masyarakat kekuatan untuk mengendalikan penyiaran melalui dewan direksi yang seharusnya menjadi perwakilan publik. Penyiaran publik diharapkan menjadi ruang publik, tempat warga masyarakat bisa mendiskusikan berbagai persoalan bersama tanpa kontrol oleh kekuatan politik, ekonomi dan sosio-kultural. Tulisan ini berdasarkan penelitian yang menggunakan studi kasus mengeksplorasi transformasi Agropolitan TV dari televisi pemerintah ke penyiaran publik lokal. Melalui wawancara mendalam dengan manajemen, kantor humas, dewan direktur, aktivis organisasi masyarakat sipil dan pemanfaatan dokumen, paper ini menemukan bahwa ATV memerlukan waktu yang lama untuk diakui secara hukum sebagai penyiaran publik lokal karena faktor eksternal dan faktor internal seperti keputusan ATV untuk bekerja sama dengan stasiun TV komersil yang dilarang oleh Undang-Undang. Meski, status ATV relatif independen, orang yang mengelola ATV adalah mereka yang memiliki kedekatan dengan pengambil kebijakan di Kota Batu.
Chat about Cars in Gran Turismo Indonesia Discussion Club: a Virtual Gemeinschaft in Netnography (Pembicaraan tentang Mobil di Gran Turismo Indonesia Discuss Club: Sebuah Virtual Gemeinschaft dalam Netnografi)
Authors: Pritadi Muhammad Ardi
Published: December 2018

The paper discusses the existence of Gran Turismo Indonesia Discussion Club (GTIDC) as a virtual gemeinschaft whose members like to play Gran Turismo (GT). Based on netnographical methodology, the research explains that offline activities of this group have developed certain norm, called fun culture, while the norms of the online ones are described as generalized reciprocity. Both norms are applied by routine activities of discussing the experience of driving cars in GT. Henceforth, this virtual gemeinschaft could be explained by physical-atomically analogy: the atom would be its social structure or virtual gemeinschaft, the flow rotation would be its discussion activities, the positive pole would be speaker or thread starter, and the negative pole would be commentators. Finally, the paper concludes that the social equilibrium could lead GTIDC to maintain social inclusion among its members. Nowadays, the use of social media like Facebook could establish such sociocultural phenomenon.
Geometric Effect for Biological Reactors and Biological Fluids

Published: December 2018

As expressed “God made the bulk; the surface was invented by the devil” by W. Pauli, the surface has remarkable properties because broken symmetry in surface alters the material properties. In biological systems, the smallest functional and structural unit, which has a functional bulk space enclosed by a thin interface, is a cell. Cells contain inner cytosolic soup in which genetic information stored in DNA can be expressed through transcription (TX) and translation (TL). The exploration of cell-sized confinement has been recently investigated by using micron-scale droplets and microfluidic devices. In the first part of this review article, we describe recent developments of cell-free bioreactors where bacterial TX-TL machinery and DNA are encapsulated in these cell-sized compartments. Since synthetic biology and microfluidics meet toward the bottom-up assembly of cell-free bioreactors, the interplay between cellular geometry and TX-TL advances better control of biological structure and dynamics in vitro system. Furthermore, biological systems that show self-organization in confined space are not limited to a single cell, but are also involved in the collective behavior of motile cells, named active matter. In the second part, we describe recent studies where collectively ordered patterns of active matter, from bacterial suspensions to active cytoskeleton, are self-organized. Since geometry and topology are vital concepts to understand the ordered phase of active matter, a microfluidic device with designed compartments allows one to explore geometric principles behind self-organization across the molecular scale to cellular scale. Finally, we discuss the future perspectives of a microfluidic approach to explore the further understanding of biological systems from geometric and topological aspects.

Published: December 2018

Obesity-related non-alcoholic fatty liver disease (NAFLD) represents the most common cause of pediatric liver disease due to overweight/obesity large-scale epidemics. In clinical practice, diagnosis is usually based on clinical features, blood tests, and liver imaging. Here, we underline the need to make a correct differential diagnosis for a number of genetic, metabolic, gastrointestinal, nutritional, endocrine, muscular, and systemic disorders, and for iatrogenic/viral/autoimmune hepatitis as well. This is all the more important for patients who are not in the NAFLD classical age range and for those for whom a satisfactory response of liver test abnormalities to weight loss after dietary counseling and physical activity measures cannot be obtained or verified due to poor compliance. A correct diagnosis may be life-saving, as some of these conditions which appear similar to NAFLD have a specific therapy. In this study, the characteristics of the main conditions which require consideration are summarized, and a practical diagnostic algorithm is discussed.

Published: December 2018

Similar text fragments extraction from weakly formalized data is the task of natural language processing and intelligent data analysis and is used for solving the problem of automatic identification of connected knowledge fields. In order to search such common communities in Wikipedia, we propose to use as an additional stage a logical-algebraic model for similar collocations extraction. With Stanford Part-Of-Speech tagger and Stanford Universal Dependencies parser, we identify the grammatical characteristics of collocation words. With WordNet synsets, we choose their synonyms. Our dataset includes Wikipedia articles from different portals and projects. The experimental results show the frequencies of synonymous text fragments in Wikipedia articles that form common information spaces. The number of highly frequented synonymous collocations can obtain an indication of key common up-to-date Wikipedia communities.

Published: December 2018

As a non-invasive diagnostic tool, Magnetic Resonance Imaging (MRI) has been widely used in the field of brain imaging. The classification of MRI brain image conditions poses challenges both technically and clinically, as MRI is primarily used for soft tissue anatomy and can generate large amounts of detailed information about the brain conditions of a subject. To classify benign and malignant MRI brain images, we propose a new method. Discrete wavelet transform (DWT) is used to extract wavelet coefficients from MRI images. Then, Tsallis entropy with DNA genetic algorithm (DNA-GA) optimization parameters (called DNAGA-TE) was used to obtain entropy characteristics from DWT coefficients. At last, DNA-GA optimized support vector machine (called DNAGA-KSVM) with radial basis function (RBF) kernel, is applied as a classifier. In our experimental procedure, we use two kinds of images to validate the availability and effectiveness of the algorithm. One kind of data is the Simulated Brain Database and another kind of image is real MRI images which downloaded from Harvard Medical School website. Experimental results demonstrate that our method (DNAGA-TE+KSVM) obtained better classification accuracy.

Authors: Wu Chan-Sheng , Tsai Ping-Hsiu , Kuo Chia-Ming , Tsai Che-Wei
Published: December 2018

The effects of atomic size difference on the microstructure and mechanical properties of single face-centered cubic (FCC) phase high-entropy alloys are studied. Single FCC phase high-entropy alloys, namely, CoCrFeMnNi, Al0.2CoCrFeMnNi, and Al0.3CoCrCu0.3FeNi, display good workability. The recrystallization and grain growth rates are compared during annealing. Adding Al with 0.2 molar ratio into CoCrFeMnNi retains the single FCC phase. Its atomic size difference increases from 1.18% to 2.77%, and the activation energy of grain growth becomes larger than that of CoCrFeMnNi. The as-homogenized state of Al0.3CoCrCu0.3FeNi high-entropy alloy becomes a single FCC structure. Its atomic size difference is 3.65%, and the grain growth activation energy is the largest among these three kinds of single-phase high-entropy alloys. At ambient temperature, the mechanical properties of Al0.3CoCrCu0.3FeNi are better than those of CoCrFeMnNi because of high lattice distortion and high solid solution hardening.

Published: December 2018

Objective: The use of high-performance sports technology to describe the physiological load of stress and the quality of recovery in a population of executives during the workday. Methodology: Heart rate variability values were recorded during 48 h from which the relationship between stress/recovery quality (stress balance) was obtained for three differentiated time slots: work, after work, and night in a workday. Results: We observed a negative stress balance during the 24 h of measurement in the course of a workday, being negative at work and after work, and positive at night. The stress generated or maintained outside working hours correlates significantly with a lower quality of recovery during the 24 h workday. Conclusions: It is necessary to prioritize strategies that help improve stress management in executives through the improvement of tools and strategies that mainly promote greater relaxation outside working hours.
Friendship of Stock Market Indices: A Cluster-Based Investigation of Stock Markets
Authors: Nagy László , Ormos Mihály
Published: December 2018

This paper introduces a spectral clustering-based method to show that stock prices contain not only firm but also network-level information. We cluster different stock indices and reconstruct the equity index graph from historical daily closing prices. We show that tail events have a minor effect on the equity index structure. Moreover, covariance and Shannon entropy do not provide enough information about the network. However, Gaussian clusters can explain a substantial part of the total variance. In addition, cluster-wise regressions provide significant and stationer results.

Published: December 2018

Schisandra Fructus (SF) is a traditional Chinese herb used in the treatment of inflammatory disorders like hepatitis. One of the main anti-inflammatory components of SF is the lignans. However, the underlying anti-inflammatory mechanism of Schisandra Chinensis lignans (SCL) remains unclear. This study aims to investigate the effects of SCL on inflammatory mediators in lipopolysaccharide-stimulated RAW264.7 cells and explore the underlying mechanism. The production of nitric oxide (NO) was determined by Griess reaction. ELISA was used to determine cytokine levels and chemokines secretion. To estimate protein levels and enzyme activities, we employed Western blotting. Nuclear localization of NF-κB, AP-1, and IRF3 was detected using immunofluorescence analyses. The results showed that SCL significantly reduced the release of inflammatory mediators, including NO and PGE2, which may be related to down-regulation of iNOS and COX-2 expression. The production of cytokines and chemokines was suppressed by SCL treatment. SCL also decreased the phosphorylation of IKKα/β, IκB-α, Akt, TBK1, ERK, p38, JNK, NF-κB (p65), AP-1 (c-Jun), and IRF3 in RAW264.7 macrophages activated with LPS. The nuclear protein levels and nuclear translocation of AP-1, NF-κB and IRF3 were suppressed by SCL. These results indicated that SCL suppressed the IKKα/β/NF-κB, MAPKs/AP-1 and TBK1/IRF3 signaling pathways in LPS-stimulated RAW264.7 macrophages.
Cassava Waste Management and Biogas Generation Potential in Selected Local Government Areas in Ogun State, Nigeria
Authors: Olukanni David O. , Olatunji Tope O.
Published: December 2018

Agricultural products such as cassava produce huge amounts of waste when processed into consumable goods. The waste generated is generally considered to contribute largely to environmental pollution. This study therefore investigates the waste management practice that is adopted by cassava processors in Ogun State, Nigeria. Five local government areas (LGAs) dominant in processing cassava were selected for the study on the basis of spatial location distribution, landmass, and population. The survey involved the use of structured questionnaires administered to cassava processors of the selected LGAs. The Statistical Package for Social Sciences (SPSS) software application and descriptive statistics were used for data analysis. Results of the analysis show that the majority (70%) of the cassava processors are females. Cassava peel constitutes 10% of the waste produced, of which 91% is heaped at refuse dumps in most communities. Results also reveal that 86.3% of cassava residues are used for animal feeds. Other findings show that the peels, when dried, are used as biofuel for cooking and there is a significant potential for biogas production. From the data captured from respondents during the study, most processors are willing to pay for an improved waste management system. The study therefore recommends the proper waste management of cassava waste to minimize environmental pollution.
Estimating Pore Water Electrical Conductivity of Sandy Soil from Time Domain Reflectometry Records Using a Time-Varying Dynamic Linear Model
Authors: Aljoumani Basem , Sanchez-Espigares Jose A. , Wessolek Gerd
Published: December 2018

Despite the importance of computing soil pore water electrical conductivity (σp) from soil bulk electrical conductivity (σb) in ecological and hydrological applications, a good method of doing so remains elusive. The Hilhorst concept offers a theoretical model describing a linear relationship between σb, and relative dielectric permittivity (εb) in moist soil. The reciprocal of pore water electrical conductivity (1/σp) appears as a slope of the Hilhorst model and the ordinary least squares (OLS) of this linear relationship yields a single estimate ( 1 / σ p ^ ) of the regression parameter vector (σp) for the entire data. This study was carried out on a sandy soil under laboratory conditions. We used a time-varying dynamic linear model (DLM) and the Kalman filter (Kf) to estimate the evolution of σp over time. A time series of the relative dielectric permittivity (εb) and σb of the soil were measured using time domain reflectometry (TDR) at different depths in a soil column to transform the deterministic Hilhorst model into a stochastic model and evaluate the linear relationship between εb and σb in order to capture deterministic changes to (1/σp). Applying the Hilhorst model, strong positive autocorrelations between the residuals could be found. By using and modifying them to DLM, the observed and modeled data of εb obtain a much better match and the estimated evolution of σp converged to its true value. Moreover, the offset of this linear relation varies for each soil depth.
Relay-Assisted D2D Transmission for Mobile Health Applications

Published: December 2018

Relay-assisted Device-to-Device (D2D) communication, one of the important transmission modes in mobile health systems, can provide high transmission quality for servicing users at the edge of system coverage. However, the quality of the D2D relay communication is largely limited by the relay nodes. When a poor node is selected to assist the source node in the data transmission, it is likely to result in the loss of medical data and inaccurate transmission. Therefore, this paper focuses on how to select relay modes and relay nodes to improve the reliability of medical data transmission. Firstly, in order to eliminate the relay nodes with low energy or poor willingness, the acceptable energy consumption metric of relay nodes is proposed in this paper. The relay mode of each relay node is determined by the acceptable energy consumption metric, which can ensure the physical reliability of the relay communication links. Then a trust metric is proposed to measure the social reliability of each relay link, further excluding the malicious relay nodes. Finally, this paper proposes a relay selection algorithm based on compromise factors (RSCF). With the help of the proposed algorithm, the reliability of the relay communication can be guaranteed, and the spectrum efficiency can be promoted greatly. The simulation results show that the relay nodes selected by RSCF algorithm can greatly improve transmission rate and reliability compared with the traditional relay-assisted D2D communication schemes.

Published: December 2018

An emerging prognostic and health management (PHM) technology has recently attracted a great deal of attention from academies, industries, and governments. The need for higher equipment availability and lower maintenance cost is driving the development and integration of prognostic and health management systems. PHM models depend on the smart sensors and data generated from sensors. This paper proposed a machine learning-based methods for developing PHM models from sensor data to perform fault diagnostic for transformer systems in a smart grid. In particular, we apply the Cuckoo Search (CS) algorithm to optimize the Back-propagation (BP) neural network in order to build high performance fault diagnostics models. The models were developed using sensor data called dissolved gas data in oil of the power transformer. We validated the models using real sensor data collected from power transformers in China. The results demonstrate that the developed meta heuristic algorithm for optimizing the parameters of the neural network is effective and useful; and machine learning-based models significantly improved the performance and accuracy of fault diagnosis/detection for power transformer PHM.
@choo: Tracking Pollen and Hayfever in the UK Using Social Media

Published: December 2018

Allergic rhinitis (hayfever) affects a large proportion of the population in the United Kingdom. Although relatively easily treated with medication, symptoms nonetheless have a substantial adverse effect on wellbeing during the summer pollen season. Provision of accurate pollen forecasts can help sufferers to manage their condition and minimise adverse effects. Current pollen forecasts in the UK are based on a sparse network of pollen monitoring stations. Here, we explore the use of “social sensing” (analysis of unsolicited social media content) as an alternative source of pollen and hayfever observations. We use data from the Twitter platform to generate a dynamic spatial map of pollen levels based on user reports of hayfever symptoms. We show that social sensing alone creates a spatiotemporal pollen measurement with remarkable similarity to measurements taken from the established physical pollen monitoring network. This demonstrates that social sensing of pollen can be accurate, relative to current methods, and suggests a variety of future applications of this method to help hayfever sufferers manage their condition.
Vulnerability Assessment of Soil and Water Loss in Loess Plateau and Its Impact on Farmers’ Soil and Water Conservation Adaptive Behavior
Authors: Huang Xiaohui , Wang Lili , Lu Qian
Published: December 2018

Analyzing vulnerability and adaptation to soil and water loss is an important part of the study on the human–environment relationship in the Loess Plateau. It has also provided a new perspective for studying the farmers’ adoption behavior of soil and water conservation technology in the soil erosion area of the Loess Plateau. Based on the Turner vulnerability framework, this paper constructs a household-scale index system of soil and water loss vulnerability in the Loess Plateau and evaluates the soil and water loss vulnerability in the Loess Plateau using the field survey data of the Loess Plateau applied entropy method. Finally, we use the binary logistic model to estimate the impact mechanism of farmers’ soil erosion vulnerability on farmers’ adoption behavior of soil and water conservation technology. The main conclusions are as follows: (1) In the total sample, susceptibility > exposure > adaptability, whereas in the Shaanxi and Gansu subsample, susceptibility > adaptability > exposure. The Ningxia subsample was similar to the total sample. For each index, Ningxia > Gansu > Shaanxi; (2) The exposure and susceptibility of soil and water loss have a positive impact on farmers’ adoption behavior of soil and water conservation technology, and natural capital has a positive impact on farmers’ adoption behavior of soil and water conservation technology. Physical capital has a positive impact on farmers’ adoption behavior of biological measures. Financial capital has a negative impact on farmers’ adoption behavior of biological measures and farming measures. Social capital has a positive impact on farmers’ adoption behavior of engineering measures and biological measures; (3) Overall, the marginal effect of the adoption behavior of farmers’ soil and water conservation techniques, adaptability > susceptibility > exposure. Therefore, it is necessary to strengthen the monitoring of soil and water loss, encourage the government and farmers to respond in time, and reduce the losses caused by soil erosion. Enriching the capital endowment of farmers, breaking through the endowment restriction of farmers’ adoption of soil and water conservation technology.
The Easier the Better: How Processing Fluency Influences Self-Efficacy and Behavioral Intention in Pro-Social Campaign Advertising
Authors: Kim Hee Jin , Jang Jung Min
Published: December 2018

This study examines how processing fluency influences people’s behavioral intention to perform a pro-social behavior. In particular, we predict that high processing fluency enhances self-efficacy perception which, in turn, increases behavioral intention to participate in a pro-social campaign. Study 1 tested the proposed effect in the context of a pro-environmental campaign. Results showed that individual’s subjective feeling of processing fluency affects the degree of self-efficacy and intention to engage in recycling behavior. Study 2 replicated study 1 in the context of organ donation. In addition, we manipulated the degree of conceptual fluency by differently pairing message framing (gain vs. loss) and background color (blue vs. red). As predicted, participants exposed to campaign advertising with conceptually matching framing-color pairs (blue—gain framing and red—loss framing) expressed a greater level of self-efficacy than those who were exposed to mismatched pairs. In addition, self-efficacy mediated the influence of the color–framing match on the intention to donate organs. Our research contributes to the existing literature by identifying critical drivers that promote actions toward pro-social campaigns. It also provides useful guidelines for marketers who design and implement pro-social campaign communications.

T Cell Memory to Vaccination
Authors: Todryk Stephen M.
Published: December 2018

Most immune responses associated with vaccination are controlled by specific T cells of a CD4+ helper phenotype which mediate the generation of effector antibodies, cytotoxic T lymphocytes (CTLs), or the activation of innate immune effector cells. A rapidly growing understanding of the generation, maintenance, activity, and measurement of such T cells is leading to vaccination strategies with greater efficacy and potentially greater microbial coverage.
CONTRACTOR SELECTION FOR PERFORMANCE‐BASED MAINTENANCE PARTNERSHIPS
Authors: Straub Ab , Mossel Henk-Jan van
Published: December 2018

Dutch housing associations use new procurement methods such as performance‐based maintenance partnerships for maintaining their housing stock. Such partnerships promise a range of advantages as compared to the traditional tendering of maintenance projects. For contractors a performance‐based approach implies major changes in methods and work processes. A major change within this performance‐based approach is contractors acting as maintenance‐engineering consultants to clients. This requires new activities to be considered, such as providing advice on maintenance strategies, the design of maintenance scenarios, performance measurements and conducting customer satisfaction surveys. The execution of these activities demands additional capabilities from the contractor. The introduction of the Quality Mark for Real Estate Maintenance VGO KEUR is a first step in quality assurance of maintenance contractors in the Netherlands. It guarantees principals that contractors are able to work according performance‐based methods and procedures. A next step in quality assurance should be to establish a clear relationship between maintenance‐engineering and consulting activities and contractor's performance outcome.

AN ANALYSIS OF DWELLING MARKET IN VILNIUS, LITHUANIA
Authors: Ambrasas Gintautas , Stankevičius Danielius
Published: December 2018

The current situation in the real estate market in Lithuania is favourable for real estate developers. Dwelling prices in Vilnius are much lower than those in other EU member‐states. However, the rate of their increase is one of the highest in the European Union. At the end of 2003, one of the causes of the purchasing boom was the anticipated rise in real estate prices, when Lithuania was gradually integrating into the European Union. The growing income of the real estate sector and high profit attracted more and more companies to real estate market. But the situation in the real estate market has changed. Therefore, to protect the investments in real estate, customers should carefully select the investment projects, paying special attention to reliability and competence of project developers. The analysis of financial indicators of six specially selected project developers made by the authors allowed them to state that not all real estate developers in the market are reliable and able to satisfy liability claims because they may face solvency problems. In some cases, indicators even warn about a threat of bankruptcy for a company. In addition to objective factors influencing the market, such as the conditions of crediting, the economic development of the state, standard of living of the population, migration, etc., some negative effects play an important role in the process of price rising. Authors analyzed the difference in price between the cheapest and most expensive dwellings in different segments of real estate market in Vilnius, Lithuania.

We use extensive spectroscopy from the MOSFIRE Deep Evolution Field survey to investigate the relationships between rest-frame optical emission line equivalent widths (W) and a number of galaxy and interstellar medium (ISM) characteristics for a sample of 1134 star-forming galaxies at redshifts 1.4 ≲ z ≲ 3.8. We examine how the equivalent widths of

, and

, depend on stellar mass, UV slope, age, star formation rate (SFR) and specific SFR (sSFR), ionization parameter and excitation conditions (O32 and

/Hβ), gas-phase metallicity, and ionizing photon production efficiency (ξ
ion). The trend of increasing W with decreasing stellar mass is strongest for

(and

+Hβ). More generally, the equivalent widths of all the lines increase with redshift at a fixed stellar mass or fixed gas-phase metallicity, suggesting that high equivalent width galaxies are common at high redshift. This redshift evolution in equivalent widths can be explained by the increase in SFR and decrease in metallicity with redshift at a fixed stellar mass. Consequently, the dependence of W on sSFR is largely invariant with redshift, particularly when examined for galaxies of a given metallicity. Our results show that high equivalent width galaxies, specifically those with high

, have low stellar masses, blue UV slopes, young ages, high sSFRs, ISM line ratios indicative of high ionization parameters, high ξ
ion, and low metallicities. As these characteristics are often attributed to galaxies with high ionizing escape fractions, galaxies with high W are likely candidates for the population that dominates cosmic reionization.
A Ground-based Near-ultraviolet Secondary Eclipse Observation of KELT-9b

Published: December 2018

KELT-9b is a recently discovered exoplanet with a 1.49 day orbit around a B9.5/A0-type star. The unparalleled levels of ultraviolet irradiation that it receives from its host star put KELT-9b in its own unique class of ultra-hot Jupiters, with an equilibrium temperature >4000 K. The high quantities of dissociated hydrogen and atomic metals present in the dayside atmosphere of KELT-9b bear more resemblance to a K-type star than a gas giant. We present a single observation of KELT-9b during its secondary eclipse, taken with the Wide Field Camera on the Isaac Newton Telescope (INT). This observation was taken in the U-band, a window particularly sensitive to Rayleigh scattering. We do not detect a secondary eclipse signal, but our 3σ upper limit of 181 ppm on the depth allows us to constrain the dayside temperature of KELT-9b at pressures of ∼30 mbar to 4995 K (3σ). Although we can place an observational constraint of A

g
 < 0.14, our models suggest that the actual value is considerably lower than this due to H− opacity. This places KELT-9b squarely in the albedo regime populated by its cooler cousins, almost all of which reflect very small components of the light incident on their daysides. This work demonstrates the ability of ground-based 2 m class telescopes like the INT to perform secondary eclipse studies in the near-ultraviolet, which have previously only been conducted from space-based facilities.
Formes littéraires à l’essai. Sur l’agentivité collective des écritures hors du livre
Authors: Murzilli Nancy
Published: December 2018

Il est convenu de regrouper sous l’étiquette de « littérature hors du livre » les pratiques qui remettent en question le modèle institutionnel dominant d’une littérature centrée sur le livre. Il s'agit toutefois de savoir comment une telle critique est non seulement menée, mais également opérante. Adoptant une démarche pragmatiste, ce texte interroge l'agentivité collective des pratiques d'écriture hors du livre. Il fait l'hypothèse que celle-ci passe par la construction de dispositifs fictionnels qui fonctionnent comme des opérateurs d’expériences de pensée instituant nos actions communes futures.
Publier : une pratique artistique
Authors: Gilbert Annette
Published: December 2018

Les pratiques de publication se sont tellement développées ces dernières années dans des zones plutôt expérimentales de l’art et de la littérature qu’elles ont fini par trouver un slogan : « Publishing as artistic practice », la publication comme pratique artistique. Faut-il comprendre de ce slogan que la publication est devenue une nouvelle branche des pratiques artistiques ou bien que seule une part de la publication peut y prétendre ? Dans certaines sphères du monde de l’art, la publication et la fabrication de livres constituent désormais un des éléments centraux des pratiques artistiques. Il n’est ainsi pas rare que l’édition et la publication soient non seulement intégrées dans la conception de l’œuvre elle-même, mais plus encore qu’elles soient l’œuvre véritable.
The Ghost in the Machine . Multimédia, algorithme et littérature artificielle
Authors: Nachtergael Magali
Published: December 2018

La littérature hors du livre, en tant qu’objet critique et d’études, s’est définie en même temps que les écritures en ligne, numériques et sur écran ont connu un essor mondial. Il s’agit dans cet article de comprendre en quoi la technogénèse (N. Katherine Hayles) conditionne la perception de ce que peut être la littérature et la critique littéraire du « hors livre ». En prenant comme point de départ les interactions entre littératures expérimentales et médiums technologiques, l’article analyse l’influence du numérique sur le canon littéraire, le déplacement de la poétique vers une approche multimédiatique et le rôle des algorithmes dans la perception du champ littéraire hors du livre.
L’antiromantisme, l’État et le marché dans la France des années 1820 et 1830
Authors: Guillot Augustin
Published: December 2018

Dès le début des années 1820, le discours antiromantique condamne son ennemi en alléguant sa dimension mercantile, fustigeant ainsi les logiques médiatiques et marchandes qui contribuent au renversement des valeurs littéraires. La réaction est d’autant plus vive que bien des auteurs hostiles à la littérature nouvelle se perçoivent en réalité comme des serviteurs de l’État, et s’investissent d’ailleurs fortement dans le monde académique et savant. Ainsi, la querelle du « classique » et du « romantique », loin de relever d’une opposition doctrinale, serait d’abord le symptôme éruptif d’une dissociation douloureuse du monde lettrée lui-même, de plus en plus déchiré entre la production institutionnelle du savoir d’un côté et la production marchande du littéraire de l’autre.
Un héritage impossible ? Les paradoxes de l’antiromantisme marxiste
Authors: Vanoosthuyse François
Published: December 2018

Bien qu’ils se projettent dans un temps d’après le romantisme, les textes du jeune Marx portent la trace des admirations et des refus, des contacts et des tensions qu’il entretient avec lui. Marx ne tient pas de discours antiromantique, et n’envisage aucune poétique qui le dévaluerait. Mais il existe un antiromantisme marxiste, dont les racines plongent dans l’histoire du mouvement prolétarien, et qui a pris à l’époque stalinienne l’aspect d’une vulgate agressive. La critique d’obédience marxiste s’en est fait ou non l’écho : le romantisme y fait débat. Cette étude interroge la diversité des discours marxistes sur le romantisme, et pointe en particulier l’écart qui sépare Marx de ceux qui revendiquent sa filiation.
EEG ENHANCEMENT USING EXTENDED KALMAN FILTER TO TRAIN MULTI-LAYER PERCEPTRON
Authors: Yakoubi Manel , Hamdi Rachid , Salah Mounir Bousbia
Published: December 2018

In many applications of signal processing, especially in biomedicine, electroencephalogram (EEG) is the recording of electrophysiological brain activity along the scalp over a small interval of time and it is a biological non stationary signal which contains important information. Analysis of EEG signal is useful to identify physiological situations of the human as normal and epileptic subject. EEG signal becomes more complicated to be analyzed by the introduction of the noise. In this paper, a nonlinear Kalman Filter scheme where an extended Kalman filter (EKF) based Multi-layer perceptron (MLP) model is proposed to remove white and colored Gaussian noises from EEG recordings in physiological and pathological states (normal and epileptic). The MLP is one of the artificial neural network (ANN) models that has great track of impacts at solving a variety of problems. Activation function is one of the elements in MLP neural network. Selection of the activation function as sigmoid in the MLP network plays an essential role on the network performance. Thus, the MLP parameters as weights, and outputs are trained by an EKF in order to minimize the difference between the output of the neural network and the desired outputs. The results comparison studies are evaluated with root mean square difference (RMSD) and signal to noise ratio (SNR). The elapsed time is decreased using this method compared to normalised least mean square (NLMS) and Meyer wavelet methods. These parameters applied to EEG signals show the validity and effectiveness of the proposed approach.
