Rethinking the role of experts and expertise in behavioural public policy
Authors: John Peter , Stoker Gerry
Published: March 2019

Nudge and behavioural public policy tools have won support from governments across the world for improving the effectiveness of public interventions. Yet nudge still attracts strong criticisms for promoting paternalism and manipulation as legitimate government actions. To move beyond this divide, this paper offers a comprehensive reorientation, which is necessary because the intellectual foundations of the policy are at fault. A more secure foundation can be achieved by expanding the cognitive scope of behavioural policy, and ensuring that it does not rely on the narrow assumption that intuitive reasoning is flawed and that expert advice is always preferable. This shift in the cognitive range of nudge moves behavioural policy toward citizen reflection and initiative, pointing away from expert-led interventions. It amounts to more than incremental advances in nudge practice. As a result, nudge can escape the charge of not respecting individual autonomy. What we call ‘nudge plus’ would link more closely with other types of governmental intervention that embrace citizen involvement.
Job precariousness among lawyers in Spain
Authors: Obiol-Francés Sandra , Santos-Ortega Antonio , Muñoz-Rodríguez David
Published: March 2019

This article stems from an interest in discovering how working conditions have changed in qualified professions in Spain, concentrating on lawyers. Using a qualitative method, we have found significant sources of precariousness that are transforming the profession's ways. Throughout this article, light has been cast on the connections between the changing professional model of the lawyer's job over the past three decades and the emergence of precarious situations. Our findings highlight that there has been a transformation in the occupation of lawyers in Spain: income and professional careers are marked by extreme uncertainty, raising psychosocial risks.

For the first time, complexes of glycyrrhetinic acid (GLA) with the antibiotic streptomycin (ST) have been studied. The complexes, obtained at different molar ratios of "host - GLA: guest - ST": 1 : 1, 2 : 1, 3 : 1 and 4 : 1, were studied using both spectrophotometry and electrospray ionization mass spectrometry. With increasing GLA concentration using spectrophotometry, the bathochromic shift of the maximum absorption of the MFR (203–210 nm) and the formation of an additional peak (260–273 nm) in the ST absorption spectrum are observed, indicating the formation of supramolecular complexes of different glycyrrhetinic acid stoichiometry with streptomycin antibiotic. Using electrospray ionization mass spectrometry, signals of nGLK-ST heterocomplexes containing GLA and CTP in the ratio of 1 : 1, 2 : 1, 3 : 1 and 4 : 1 were recorded, respectively. It has been shown that with increasing GLA concentration, the supramolecular structures are enlarged due to an increase in the number of GLA molecules in its composition.

The presented data can be used in the development of a new dosage form of streptomycin based on supramolecular complexes with GLA.

A fragment of the supramolecular structure of lignin was simulated by cross-linking the C546H600O196 structural units along the corresponding CH–bonds followed by geometric optimization by the Polac-Ribier’s conjugate gradient method in the MNDO field of the HyperChem 8.0 software and ChemBio 13.0. The pore structure of lignin was simulated as well with optimization by the molecular mechanic’s method according to the MM2 Norman-Alinger’s algorithm taking into account the dipole-dipole interaction. Сoumaric alcohol molecule was a building block. The calculation of the energy parameters of lignin’s pore structure filling by the molecules of organic substances and water were carried out. It included a search for a global minimum of the potential energy by the molecular mechanic’s method according to the MM2 program and by the molecular dynamics method. The calculation had its basis in the “closed” pores existence in lignin. The calculated values of pore volume and specific surface area correlate with the experimental data. The way of prediction of organic substances sorption activity to lignin was proposed. This is evident from their calculated hydrophobicity parameter that correlates with the interaction energy of the molecules in the lignin pore.

Specific features of fluoride accumulation by two species of herbaceous plants – Chamerion angustifolium (L.) Holub and Tanacetum vulgare L., were found at different distances from the aluminum smelter located in the Baikal region. The highest fluorine content was recorded at the distance of 3 km from the smelter: 433 mg / kg of dry weight in C. angustifolium, 306 mg / kg in T. vulgare. According to the level of accumulation of fluorine, the organs of C. angustifolium were arranged in the following order (as the concentration decreases): leaves> roots> stems ≥ flowers, for T. vulgare the another sequence was typical: roots> leaves> flowers ≥ stems. Calculation of the root barrier coefficient for different organs of C. angustifolium and T. vulgare indicates the existence of barrier mechanisms that prevent the entry of fluorine from the soil into the aerial part of plants. A feature of the accumulation of fluoride in the leaves of C. angustifolium is its active foliar absorption and barrier-free intake from the soil. It has been established that the rate of fluoride accumulation by the reproductive organs of both species is much lower than by the assimilation organs. The data obtained make it possible to recommend using C. angustifolium for monitoring air fluorine pollution, and T. vulgare – for soil fluorine pollution.

Fiberboards are producing of vegetable raw materials and urea-formaldehyde glues. The necessity to bind formaldehyde led to the search for modifiers that are capable to reduce the toxicity of wood boards without impairment of their physico-mechanical properties. It was researched how guanylurea sulfate influences on some process, which are occur during the formation of wood boards. The salts were synthesized at molar ratios of cyanoguanidine : sulfuric acid from 1 : 0.1 to 1 : 0.5 and their effects on the technological parameters of the glue were investigated. It was found that in combination with the urea-formaldehyde resin guanylurea sulfate sworn GUS-0.5 synthesized at a 1 : 0.5 molar ratio is most suitable as it accelerates hardening of the resin without negative influence on other standard parameters. Physicochemical tests and 13C solid-state NMR spectroscopy have shown that upon injection into the glue GUS-0.5 reacts with the functional groups of the urea-formaldehyde oligomer while embedding into the structure of the curing resin. At temperatures of hot pressing of wood boards in case of injection into the composition separately from the glue GUS-0.5 is subject to thermal transformations with the formation of ammonia. It’s shown that the properties of fiberboards depend on the method of injection of the modifier into the composition. To effectively reduce toxicity without impairment of their physico-mechanical properties should be used a combined method of using the modifier when one half is injected into the glue and the other half separately.

Aqueous suspensions of nanocrystalline cellulose (NCC) were obtained by sulfuric acid hydrolysis using the standard procedure. Suspensions, films and airgel of NCC were characterized by various methods: the degree of polymerization was determined, elemental analysis was carried out, the degree of crystallinity and crystallite size were calculated on the basis of X-ray data, the morphology of NCC aerogels was studied using scanning electron microscopy. The particle size of the NCC was determined using a transmission electron microscope, a scanning atomic-force microscope and the method of dynamic light scattering. NFC hydrosols with different pH were used to prepare lyophilized NCC samples. From NCC hydrosols with pH 2.2, by gradual replacement of water with an organic solvent, NCC organogels with acetone, acetonitrile and ethanol were obtained.

The process of dispersion of lyophilized NCC and NCC organogels (acetone, acetonitrile and ethanol) in water and in 11 organic solvents was investigated. The effect of the pH of the initial aqueous suspension of the NCC and the solvent forming the NCC organogel on the repeated dispersibility of the NCC is shown. The optimum pH value of the initial aqueous suspension of NCC was determined, which determines the maximum dispersibility of the lyophilized samples in each specific solvent. It was shown that dispersion of acetone, acetonitrile and ethanol organogels in most of the solvents studied occurs with the formation of particles less than 100 nm.

The composition of lipophilic components of sea buckthorn leafy shoots, a large tonnage waste in the production of sea buckthorn oil and during renewing the cultural plantings of sea buckthorn, was studied. Tert-butyl methyl ether (TBME) was used as an extraction solvent for raw materials having all the advantages of diethyl ether, but devoid of its disadvantages. It does not form peroxides and does not create increased gas content due to the higher boiling point. The chemical composition of the TBME extract of sea buckthorn leafy shoots was studied by gas chromatography–mass-spectrometry and high-performance liquid chromatography. Seventy-four neutral and thirty-eight acidic components, including polyprenols, dolichols, triterpene alcohols and acids, sterols, were identified. TBME as an extragent provides more high yields of bioactive triterpenoic acids and diols including uvaol, eritrodiol and betulin in comparison with n-hexane. These compounds can increase some useful properties of obtained extract.
USE OF FINELY GROUND RECYCLED CONCRETE FOR IMPROVEMENT OF INTERFACIAL ADHESION IN FIBER-REINFORCED CEMENTITIOUS COMPOSITES
Authors: Hlůžek Radim , Trejbal Jan
Published: March 2019

This paper deals with an improvement and an assessment of a polymeric macro-fibers adhesion to the cement matrix. For this purpose, two approaches were employed – (i) roughening of fibers using a plasma treatment and (ii) an addition of finely ground recycled concrete (amount 30 wt. %) to the matrix ensuring the roughness of interfacial zones. Polyethylene terephthalate (PET) and polypropylene (PP) fibers, both ca. 0.3mm in a diameter, were used. These were surface roughened using a cold oxygen plasma treatment and then observed by means of the scanning electron microscopy. Consequently, pull-out tests of an individual fiber embedded 25mm in the matrix were performed, while the force needed for fiber pullout was recorded. Results have shown that plasma treated fibers reached on a better adhesion with the matrix by up to ca. 5% (PET) and 20% (PP), if compared to reference fibers. When recycled concrete was used, the adhesion increased further by about 5–10% for both fiber types.

Published: March 2019

Alkali activated fly ash is a widely used admixture to the concrete. Due to the pozzolanic activity, the fly ash can replace up to 60 mass percentage. The impact of fly ash on the concrete depend on the level of it content, i.e. in small levels it improves the macro-mechanical properties and durability as well as chemical resistance. On the other side, fly ash admixture negatively influence the set time and cause slow development of strength. Therefore, the effect of small fly ash admixture levels on the micro-structure of high performance concrete (HPC) is discussed in this study.

Detection and Identification of Ditylenchus dipsaci from Imported Garlic BulbsImportation rate of garlic (Allium sativum) increased significantly in Indonesia lately. This situation may lead to the introduction and spread of quarantine pests, one of them is bulbborne nematode Ditylenchus dipsaci. This research is aimed to detect and identify the presence of D. dipsaci on imported garlic bulb from China. Samples of garlic bulbs were taken from imported garlic through Tanjung Priok Sea Port, North Jakarta, within importation period from August to December 2017. Nematode extraction was performed by modified Baermann funnel method. Nematode identification was carried out based on the D. dipsaci key morphological characters and morphometry according to de Man formula. This nematode was successfully detected from 20% of garlic bulbs samples based on morphological characteristics, i.e.  slender body shape, body length between 0.56 until 1 mm, well-defined stylet (10-13 mm in length), posterior valve between oesophagus and intestine is not overlapping, median bulb obvious with oval shape, and the tail was conoid with a pointed terminus. The findings of D. dipsaci is an important fact because these nematodes have the potential to cause damage to plants in the field.

Krzysztof Kieślowski employed film properties in a creative way in his Three Colours (Trois couleurs, 1993–94) trilogy. They play various roles in Blue (Bleu, 1993), White (Blanc, 1993) and Red (Rogue, 1994): they make the presented world more probable, co-create images of heroes, build dramaturgy and convey symbolic content. Such a treatment of film props is shaped by the director’s film style and creates a specific cinematic atmosphere.
LANGUAGE AND CULTURE LEARNING STRATEGIES IN A STUDY ABROAD CONTEXT
Authors: Róg Tomasz
Published: March 2019

This article takes a step towards bridging the research gap between language-and-culture learning strategies and SLA-oriented outcomes of study abroad programmes. While studies concerning the impact of studying in foreign countries document various language-related benefits of the experience, only a handful addresses the types of language and culture learning strategies employed by study abroad participants. The present study tracks the use of these strategies by Polish students of English philology participating in a semester-long exchange programme in Portugal and Romania. It is revealed that although the use of language and culture learning strategies does not change significantly over the course of students’ stay abroad, the strategies chosen before their departure are used rather consistently.
DEVELOPING WRITING STRATEGIES OF POOR LANGUAGE LEARNERS AT THE LEVEL OF JUNIOR-HIGH SCHOOL
Authors: Droździał-Szelest Krystyna , Domińska Mirosława Anna
Published: March 2019

Although language learning strategy research has been going on for almost forty years and has provided both theorists and practitioners with an abundant body of knowledge on the subject, there are still areas that need further investigation. One such area is the use of strategies in language skills development, with the skill of writing being singled out as deserving special attention. It is suggested that in order to better understand the processes involved, we need more information concerning the development of the skill by learners, as well as more data revealing the effects of strategy based instruction, especially with reference to children and adolescents in different foreign language learning contexts.   Hence, this article makes an attempt to contribute to the ongoing discussion by focusing on a special group of learners – poor language learners, at a risk of educational failure – who are learning a foreign language (English) in the context of junior high school. The article consists of two parts: its theoretical sections focus on some issues related to poor language learners, with emphasis on factors impacting their school problems in general and learning of the writing skill in particular. Then, based on the literature review, some research findings concerning writing strategies and the effects of strategic training are discussed. The second part presents and comments on the data obtained during the course of an informal study carried out in a junior high school within the framework of an educational project which was remedial in character.

Authors: Pudo Dorota
Published: March 2019

Research on subjective (implicit) theories, similarly to studies on other kinds of beliefs, has a rich tradition in the SLA field. This study presents the results of a survey conducted among 55 Romance Philology students, containing open-ended questions about different aspects of the language learning process: nature of the language itself, learner's personal attributes facilitating learning, effective learning activities, optimal learning environment, obstacles to learning, role played by other people. Due to the use of a qualitative methodology (open-ended questions), a large variety of different answers was collected. The data were analysed and divided into subject categories, and the answers falling into each category were counted in order to provide an overall view of the group's tendencies. The students' answers mainly confirm that they see learning a language as a long process demanding time and effort. Students' motivation and perseverance prove to be the most important factors whereas features such as intelligence or language aptitude are underestimated.

The present paper investigates the relationships between language learning strategies and their determinants, such as learners’ gender, their area of studies, and personality traits. It describes a study conducted on a group of 199 students of the Faculty of Social Sciences at Adam Mickiewicz University in Poznań. The results of the study indicate that a number of statistically significant relationships exist between strategy use and other individual variables, e.g. gender, level of proficiency, or learners’ area of studies. Moreover, the authors of the study make an attempt to identify and characterise students’ profiles in terms of their personal characteristics and strategic preferences so as to cast light on various paths to foreign language proficiency.

The main aim of this paper is to report the outcomes of a questionnaire study diagnosing children’s level of motivation to master English and its potential correlates, conducted among 78 primary school second graders attending one of the biggest public primary schools in Wrocław, Poland. The presentation of results is preceded by a brief overview of motivation models in SLA and analysis of earlier theoretical discussions and research in this area. The data suggest that the motivation level of the participants was high. Interestingly, the internal factors were found to be stronger correlates of motivation intensity (r = .68) than external factors (r = .40/ r = .42). More specifically, the factors most strongly related to motivation were as follows: integrative motives (r = .67), L2 user self-perception (r = .58) and aesthetic assessment of the target language (r = .54).
Villains, Ghosts, and Roses, or, How to Speak with the Dead
Authors: Huber Sandra
Published: March 2019

If narratives that uphold secular humanism have led to an “unparalleled catastrophe” as Sylvia Wynter notes in an interview with Katherine McKittrick, then it is time to unwrite them. In this essay, I examine the dead as a category that exceeds metaphysical classifications of subject and object and provides alternate possibilities of communication and hybridity. To do so, I call on work by Claire Colebrook, Jacques Derrida, John Durham Peters, Eve Tuck, and Unica Zürn, among others, with the cultural work and words of Sylvia Wynter as a guide and galvanising force. Here, I repopulate the life/death seam with gorgons, witches, fates, and revenge stories. If ghosts are seen simply as other beings, albeit taboo ones like bacteria, or require alternate cultural narratives like villains, or exist both in the symbolic sphere of the mystical and the so-called natural world like roses, what kinds of methodologies can be opened? What do the dead have to say and how do we listen?

Dub in the Front Room: Migrant Aesthetics of the Sacred and the Secular
Authors: McMillan Michael
Published: March 2019

This article aims to explore, how the struggle over the sacred and the secular is enacted within the material culture of the front room as an index of the double consciousness that takes place in the black every day. The scared is often reduced to the purely religious, but unshackling it, and engaging with the sacred as a spectrum of spiritual experience that illuminates its dialogic relationship with the political, and therefore the secular. Reclaiming the sacred provides a critical praxis towards decolonising the legacy of coloniality in the context of postcolonial modernity. As a cultural institution of self-making, valorising the material culture of the front room as a space of black interiority resists the racist trope that we live on the street, and have no homes to go to, with families and values. This interiority has shaped, and been shaped by the cultural politics of postwar Caribbean migration, and reveals the rich complexity of “black domestic life” that the “generality of society” rarely understands. Connecting the spiritual with the political provides a psychic recuperation towards resisting and healing from trauma as a process in an ongoing structuring of colonial power, cultural imperialism, and racial violence. This article will draw on research in curating my installation-based exhibitions, The West Indian Front Room (2005-06) and Rockers, Soulheads and Lovers: Sound Systems Back in da Day (2015-16).
Sacred Languages of Pop: Rooted Practices in Globalized and Digital French Popular Music
Authors: Spanu Michael
Published: March 2019

Nowadays, popular music artists from a wide range of cultures perform in English alongside other local languages. This phenomenon questions the coexistence of different languages within local music practices. In this article, I argue that we cannot fully understand this issue without addressing the sacred dimension of language in popular music, which entails two aspects: 1) the transitory experience of an ideal that challenges intelligibility, and 2) the entanglement with social norms and institutions. Further to which, I compare Latin hegemony during the Middle Ages and the contemporary French popular music, where English and French coexist in a context marked by globalisation and ubiquitous digital technologies. The case of the Middle Ages shows that religious control over Latin led to a massive unintelligible experience of ritual singing, which reflected a strong class divide and created a demand for music rituals in vernacular languages. In the case of contemporary French popular music, asemantical practices of language are employed by artists in order to explore alternative, sacred dimensions of language that challenge nationhood.

Background

Acute rejection (AR) is one of the most frequent complications after kidney transplantation (KT). Scientific evidence reports that some single-nucleotide polymorphisms (SNPs) located in genes involved in the immune response and in the pharmacokinetics and pharmacodynamics of immunosuppressive drugs are associated with rejection in renal transplant patients. The aim of this study was to evaluate some SNPs located in six genes: interleukin-10 (IL-10), tumor necrosis factor (TNF), adenosine triphosphate-binding cassette sub-family B member 1 (ABCB1), uridine diphosphate glucuronosyltransferase family 1 member A9 (UGT1A9), inosine monophosphate dehydrogenase 1 (IMPDH1) and IMPDH2.

Methods

We enrolled cases with at least one AR after KT and two groups of controls: patients without any AR after KT and healthy blood donors. Genetic analysis on DNA was performed. The heterozygosity (HET) was determined and the Hardy-Weinberg equilibrium (HWE) test was performed for each SNP. The sample size was calculated using the QUANTO program and the genetic associations were calculated using the SAS program (SAS Institute Inc., Cary, NC, USA).

Results

In our previous preliminary study (sample size was not reached for cases), the results showed that patients with the C allele in the SNP rs1045642 and the A allele in the SNP rs2032582 of the ABCB1 gene had more frequent AR. In contrast, with the achievement of sample size, the trend of the previous data was not confirmed.

Conclusions

Our study highlights a fundamental aspect of scientific research that is generally presumed, i.e. the sample size of groups enrolled for a scientific study. We believe that our study will make a significant contribution to the scientific community in the discussion of the importance of the analysis and the achievement of sample size to evaluate the associations between SNPs and the studied event.

Background

Specific metabolic changes during physiological pregnancy are characterized by hyperlipidemia and increased oxidative stress. However, these specific changes raise the question of their pro-atherogenic potential during pregnancy and their influence on the risk of developing cardiovascular disease (CVD) in women later in life, as well as complications during pregnancy. The aim of this study was to investigate the changes in lipid indexes and parameters of lipid peroxidation in non-complicated pregnancy in order to estimate their course of change and potential relationship during non-complicated pregnancy.

Methods

The study included 43 healthy pregnant women and 38 non-pregnant healthy women, in appropriate ages, as the control group. Lipid parameters and oxidative stress parameters were monitored in a longitudinal study in the first, second and third trimesters, and before delivery during non-complicated pregnancy.

Results

Results have shown that lipid indexes rise during pregnancy. The values were significantly increased when compared to the first trimester in all lipid indices and in comparison with the control group. Thyobarbituric acid reactive substances (TBARS) and lipid hydroperoxides (LOOH) were not changed significantly during physiological pregnancy, but LOOH showed a significantly higher value in the first trimester compared with the control group. Prooxidative-antioxidative balance (PAB) significantly increases as pregnancy progresses.

Conclusions

We observed the changes in lipids, lipid indexes and parameters that indicate oxidative modification of lipids in physiological pregnancy that may lead to an atherogenic, prooxidant state.

Infertility patients are willing to travel abroad to receive the medical treatment of choice. A 2010 study reported that approximately 25,000 couples travel abroad annually seeking infertility treatment. The purpose of this review is to analyze the criteria and risks related to cross-border reproductive care (CBRC) from the perspective of the patients and explore the issues raised regarding the country of origin and the destination country. A computerized search was performed in PubMed employing respective keywords. The total number of published articles provided by our PubMed search was 1905. Criteria for selecting the destination country include: the economic status, legislation, quality of care and anonymity. Despite the fact that CBRC is becoming a familiar concept, it raises concerns for the practitioner and issues of a social and bioethical nature. Most of them stem from the fact that health care acquires a commercialization aspect. Medical tourism entails several risks, such as misconceptions regarding the destination country, and legal issues arising from differences in the judiciary systems. Larger studies evaluating all aspects of CBRC are imperative. Quality assurance, a consensus and a common platform of practice, along with a system of international governance based on human rights, are a necessity for CBRC patients.

Published: March 2019

This article discusses the creation of a 3D archive and physical copies of paper reliefs (estamages). A matrix of the estampage is fabricated by the combined use of 3D scanning technology and additive technologies which can then be used for the documentation and conservation of the original estampage. In order to digitize the relief, an optical 3D scanner based on structured light was used and the processing of the 3D model is discussed in detail. Scanning data is uploaded into the microprocessor of a 3D laser printer using stereolithography technology which then creates a conservation matrix. The accuracy of relief reproduction is assessed by comparing its 3D model with 3D models of replicas obtained with the help of 3D printers. The experimental research showed that it is possible to create 3D archives and reproduction of reliefs. This approach is fundamentally new in the practice of museums and archives.
Nonlinear Model Predictive Control Strategy for Limit Management of Aero-Engines
Authors: Du Xian , Ma Yan-Hua , Sun Xi-Ming
Published: March 2019

A Min-Max structure combined with several linear limit controllers are utilized for conventional aero-engines safety control, which is complex and conservative, therefore a new nonlinear model predictive control strategy is proposed that owns the ability to manage time-varying input/output limits during acceleration/deceleration transient states of aero-engines. Penalty function items are constructed according to the characteristics of input/output limits, and are incorporated in the cost function of online receding horizon optimization for limit management of aero-engines. Considering the large computational burden of nonlinear component-level aero-engine model directly used as prediction model, a piecewise linear model is built to describe the steady-state and dynamic properties of aero-engines and its design process is explained in detail. Further, computational efforts are investigated as control horizon, prediction horizon are varied in the improved nonlinear predictive controller. Particularly, when penalty function items are activated, control performance and computational burden are examined, thus providing guidelines for key parameters tuning. Simulations show two clear results. One is that computational efforts become larger for bigger control horizon or prediction horizon, but it depends more on control horizon than prediction horizon. The other is that the proposed method can handle time-varying input/output limits effectively without resulting in a great increase of computational burden.
Differential Diffusion of Impurities in Isotopic Lithium Matrices
Authors: Lodding A. , Ott A.
Published: March 2019

The diffusion of 22Na and 195Au has been investigated in solid, isotopically pure 8Li and 7Li metal. The Na tracer has been found to diffuse by about 4 % faster in 8Li than in 7Li. For Au the corresponding difference was 4% at the melting point, but as much as about 15% at 2
3 Tm (°K). A formalism is given for the interpretation of diffusion experiments where the matrix isotope mass is varied. The present results for Na in Li can be plausibly explained in terms of the vacancy mechanism. For Au diffusion in Li, the interpretation appears incompatible with a simple vacancy mechanism, and the anomalous departure from the inverse root mass relationship can be connected with recently detected quantum effects in 6Li - 7Li mutual diffusion
Building Medieval Worlds
Authors: Fleisher Jeffrey
Published: March 2019

This paper describes a course that I developed and co-taught with Dr. John Hopkins at Rice University in the spring of 2014, entitled “Virtual Reconstruction of Historic Cities.” In this course, student teams worked to digitally reconstruct ancient Roman and Swahili buildings. The final products followed from a semester-long engagement with research on these pasts, working with archaeological and textual sources, draft iterations of buildings, then digitally modelling the structures and building them into 3D worlds in open-source gaming software. In this paper, I describe the background to the course, how it was organized, and how the course unfolded.
A survey of the management of 16–18-year-olds presenting with diabetic ketoacidosis in the UK: a need for standardisation
Authors: Dhatariya Ketan , Winocour Peter , Raffles Andrew
Published: March 2019

Background: The standard of care of 16–18-year-olds presenting with diabetic ketoacidosis (DKA) is uncertain. It is unknown who looks after them or what guidelines are used to manage their DKA.Methods: We carried out a survey using a standardised questionnaire sent to diabetes and emergency care teams across the UK using mailing lists from the Association of British Clinical Diabetologists, The Diabetes Specialist Nurse Group (UK) and the British Society of Paediatric Endocrinology and Diabetes.Results: There was a relatively poor response rate; only 32 completed questionnaires were received between May and November 2018. The data suggest that the care was highly variable across the UK. There were no consistencies on how ‘16–18 years old’ was defined; who looked after them either during the acute phase once they had been triaged through the emergency department or during the later stages of their admission; or what guideline was used to treat their DKA. Several other aspects of care were also varied.Conclusions: The care of 16–18-year-olds presenting with DKA needs to be standardised across the UK. Furthermore, because a large number are looked after by adult non- specialist general medical teams, there is a clear need to ensure a consistent straightforward joint guideline that can be readily applied in all acute clinical settings regardless of whether care takes place in a paediatric or an adult clinical setting.

Published: March 2019

The article presents an advanced driver assistance system (ADAS) based on a situational recognition solution and provides alert levels in the context of actual traffic. The solution is a process in which a single image is segmented to detect pedestrians’ position as well as extract features of pedestrian posture to predict the action. The main purpose of this process is to improve accuracy and provide warning levels, which supports autonomous vehicle navigation to avoid collisions. The process of the situation prediction and issuing of warning levels consists of two phases: (1) Segmenting in order to definite the located pedestrians and other objects in traffic environment, (2) Judging the situation according to the position and posture of pedestrians in traffic. The accuracy rate of the action prediction is 99.59% and the speed is 5 frames per second.
A DIGITAL CERTIFICATION MANAGEMENT MECHANISMS AND SECURITY ROUTING PROTOCOL IN MOBILE AD HOC NETWORK
Authors: Ngoc Luong Thai , Tu Vo Thanh
Published: March 2019

Routing services in Mobile Ad hoc Network (MANET) are the goal of denial of service (DoS) attack forms, such as: Blackhole, Sinkhole, Grayhole, Wormhole, Flooding and Whirlwind. There are some related researches to improve of security performance of routing services, such as H(AODV), OTP_AODV, SAODV and ARAN. They require hypothetical conditions that public key infrastructure (PKI) is available.  TAMAN routing protocol supported a digital certificate verification service adaptively and quickly to the dynamic topology of the network without relying on any certification authorities (CA). However, node's digital certificate is installed manually and TAMAN has not digital certificate provision and revocation mechanisms. Hence, it is restricted to operate on MANET  where nodes move randomly. In this article, we propose a Digital Certification Management Mechanisms (DCMM) based on X.509 standard which supports storing digital certificate, provision and revocation without any PKI. We have implemented DCMM on TAMAN protocol and simulated with NS2 using static and mobility scenarios with speed 30m/s. Simulation results show that digital certificates providing process completely after 70 seconds for 100 member nodes using static scenario and 270 seconds using mobility scenario, and TAMAN performance using DCMM is reduced slightly in terms of packet delivery ratio, end-to-end delay and routing load.

Published: March 2019

The dissimilarity measures between fuzzy sets/intuitionistic fuzzy sets/picture fuzzy sets are studied and applied in various matters. In this paper, we propose some new dissimilarity measures on picture fuzzy sets. This new dissimilarity measures overcome the restrictions of all existing dissimilarity measures on picture fuzzy sets. After that, we apply these new measures to the pattern recognition problems. Finally, we introduce a multi-criteria decision making (MCDM) method that used the new dissimilarity measures and apply them in the supplier selection problems.
A Feature-Based Model for Nested Named-Entity Recognition at VLSP-2018 NER Evaluation Campaign
Authors: Pham Minh Quang Nhat
Published: March 2019

In this report, we describe our participant named-entity recognition system at VLSP 2018 evaluation campaign. We formalized the task as a sequence labeling problem using BIO encoding scheme. We applied a feature-based model which combines word, word-shape features, Brown-cluster-based features, and word-embedding-based features. We compare several methods to deal with nested entities in the dataset. We showed that combining tags of entities at all levels for training a sequence labeling model (joint-tag model) improved the accuracy of nested named-entity recognition.
