Sustainable Decision-Making in Road Development: Analysis of Road Preservation Policies
Authors: Ruiz Angie , Guevara Jose
Published: January 2020

Road infrastructure in appropriate conditions is a requirement for the development of any country. The formulation of policies oriented to preserve road networks responds to political, socio-economic, and environmental interests. Through a hybrid methodology that integrates system dynamics (SD) and analytic hierarchical process (AHP) approaches, this paper compares some strategies employed in the development of sustainable road maintenance policies in Colombia. Using a hypothetical case study of a national road network, a set of maintenance policy alternatives are evaluated through the SD model in order to analyze the evolution of road conditions, and quantify costs and emissions. Then, a multi-criteria evaluation is performed applying the AHP methodology. Results show that in the Colombian context, decision-making processes regarding maintenance policies are highly influenced by economic factors, which lead to short-term strategies such as performing corrective maintenance over predictive maintenance. However, further analysis demonstrates that predictive maintenance allows the road network to remain in good conditions. Simultaneously, roadways in adequate conditions contribute to mitigate the environmental impact, because CO2 emissions are directly related to the interventions performed to preserve these roads. The proposed methodology can be used as a support tool to formulate maintenance policies that consider the long-term effects at the technical, environmental, and economic levels.
Treatment Assessment of Road Runoff Water in Zones filled with ZVI, Activated Carbon and Mineral Materials
Authors: Fronczyk Joanna , Markowska-Lech Katarzyna , Bilgin Ayla
Published: January 2020

Reducing the discharge of contaminants present in runoff water is important for a clean environment. This paper analyses field test results of three pilot-scale horizontal runoff water treatment zones filled with mixtures of zero valent iron (ZVI), activated carbon (AC), silica spongolite (SS), zeolite (Z), and limestone (LS). The investigated systems were (S1) ZVI/AC/SS, (S2) ZVI/AC/Z and (S3) ZVI/AC/LS. The efficiency of the three systems in the removal of Cd, Cu, Ni, Pb, Zn, COD and ammonium ions from runoff water was compared and the factors (temperature, pH, redox potential, hydraulic conductivity) and relationships affecting treatment effectiveness were determined. A statistical analysis of effluent contaminant concentrations and physicochemical parameters of effluent solutions included descriptive statistics, analysis of variance (ANOVA), a multidimensional analysis using a Principal Component Analysis (PCA), a factor analysis (FA) and a cluster analysis (CA). The ANOVA and cluster analyses indicated similarities between systems containing SS and LS. As a consequence, using cheaper SS can reduce investment costs. In addition, there were no significant differences between the three systems regarding Cd and Ni removal, while Cu and Pb were removed to almost 100%. The results indicate that all the tested materials supported ZVI and AC in the removal of heavy metals in a similar way. However, runoff water was enriched with nitrogen oxides and sulfates while flowing through treatment zones with SS and LS. The enrichment increased with increasing temperature and redox potential. The conducted analyses indicate that the most suitable mixture is ZVI/AC/Z. It should be emphasized that the ongoing processes (precipitation and ZVI corrosion) reduced the hydraulic conductivity of the filters up to two orders of magnitude. Expansive iron corrosion was the most limiting factor in ZVI filtration systems. In the future, applications decreasing the percentage of ZVI in the mixture are suggested.

Published: January 2020

New and cutting-edge technologies causing deep changes in societies, playing the role of game modifiers, and having a significant impact on global markets in small and medium-sized towns in Europe (SMSTEs) are the focus of this research. In this context, an analysis was carried out to identify the main dimensions of a model for promoting innovation in SMSTEs. The literature review on the main dimensions boosting the innovation in SMSTEs and the methodological approach was the application of a survey directed to experts on this issue. The findings from the literature review reflect that technologies, governance, and sustainability dimensions are enablers of SMSTEs’ innovation, and based on the results of the survey, a model was implemented to boost innovation, being this the major add-on of this research.
Curvature Invariants for Charged and Rotating Black Holes
Authors: Overduin James , Coplan Max , Wilcomb Kielan , Henry Richard Conn
Published: January 2020

Riemann curvature invariants are important in general relativity because they encode the geometrical properties of spacetime in a manifestly coordinate-invariant way. Fourteen such invariants are required to characterize four-dimensional spacetime in general, and Zakhary and McIntosh showed that as many as seventeen can be required in certain degenerate cases. We calculate explicit expressions for all seventeen of these Zakhary–McIntosh curvature invariants for the Kerr–Newman metric that describes spacetime around black holes of the most general kind (those with mass, charge, and spin), and confirm that they are related by eight algebraic conditions (dubbed syzygies by Zakhary and McIntosh), which serve as a useful check on our results. Plots of these invariants show richer structure than is suggested by traditional (coordinate-dependent) textbook depictions, and may repay further investigation.

Zika virus (ZIKV) is a mosquito-borne flavivirus associated with a febrile illness as well as severe complications, including microcephaly and Guillain-Barré Syndrome. Antibody cross-reactivity between flaviviruses has been documented, and in regions where ZIKV is circulating, dengue virus (DENV) is also endemic, leaving the potential that previous exposure to DENV could alter clinical features of ZIKV infection. To investigate this, we performed a retrospective case-control study in which we compared Canadian travellers who had been infected with ZIKV and had serological findings indicating previous DENV or other flavivirus exposure (n = 16) to those without any previous exposure (n = 44). Patient samples were collected between February 2016 and September 2017 and submitted to Public Health Ontario for testing. ZIKV infection was determined using real-time RT-PCR and antibodies against DENV were identified by the plaque-reduction neutralization test. The mean time from symptom onset to sample collection was 5 days for both groups; the magnitude of viremia was not statistically different (Ct values: 35.6 vs. 34.9, p-value = 0.2). Clinical scores were also similar. Our findings indicate that previous DENV or other flavivirus exposure did not result in greater viremia or a higher illness score.

Maximizing band degeneracy and minimizing phonon relaxation time are proven to be successful for advancing thermoelectrics. Alloying with monotellurides has been known to be an effective approach for converging the valence bands of PbTe for electronic improvements, while the lattice thermal conductivity of the materials remains available room for being further reduced. It is recently revealed that the broadening of phonon dispersion measures the strength of phonon scattering, and lattice dislocations are particularly effective sources for such broadening through lattice strain fluctuations. In this work, a fine control of MnTe and EuTe alloying enables a significant increase in density of electron states near the valence band edge of PbTe due to involvement of multiple transporting bands, while the creation of dense in-grain dislocations leads to an effective broadening in phonon dispersion for reduced phonon lifetime due to the large strain fluctuations of dislocations as confirmed by synchrotron X-ray diffraction. The synergy of both electronic and thermal improvements successfully leads the average thermoelectric figure of merit to be higher than that ever reported for p-type PbTe at working temperatures.
Effect of Combinations of Mycobacteriophages and Drugs against Mycobacterium Spp.
Authors: Satish Rajitha , Desouza Anita
Published: January 2020

The emergence of multidrug-resistant tuberculosis (MDR-TB) is a matter of global concern. The use of mycobacteriophages alone or in combination with antibiotics could be used as an alternative approach to treat drug-resistant Mycobacteria. The aim of the study was the evaluation of the effect of an isolated mycobacteriophage in combination with Isoniazid, Rifampicin, Streptomycin, and Ampicillin against Mycobacterium tuberculosis and Mycobacterium smegmatis. Determination of the MIC of the above drugs for each strain was done by the standard tube dilution method. Further, the inhibitory effect of varying drug concentrations in combination with different dilutions of the mycobacteriophage was studied. The growth inhibition pattern for both the organisms was also studied in the presence of different dilutions of mycobacteriophage by turbidometric and resazurin dye reduction method. The killing pattern of drugs, at concentrations below the MIC, when combined with mycobacteriophage, was determined. The phage induced lysis of bacteria assisted in decreasing the inhibitory concentration of the drugs.

Achieving greater crop yields remains a pressing challenge for both farmers and governments. This research examines the use and implementation of Gradient Boosting Regression in predicting crop yields for numerous districts in France. XGBoost, an efficient, optimized and flexible distributed gradient boosting library was used. Agricultural data was sourced from the CLAND Institute’s ‘Crop Data Challenge 2018’, which contains approximately 38 years of maize data compiled by various departments from the months of January to September from regions in France. Average monthly climatic parameters such as evapotranspiration, maximum and minimum temperature, cumulative precipitation, yield anomaly, solar radiation levels and an irrigation coefficient were used as input variables. The best result obtained was an RMSE value of 0.755 and MAE error of 0.54 was obtained using a tuned XGBoost Regressor trained on original variables. This paper aims to compare various regression techniques in order to improve yield prediction thus giving farmers a chance to improve their cultivation with better insights as well as enabling them to harness the power of predictive analytics.

A survey of perioperative clinician’s knowledge and application of the law regarding the classification of deaths in the perioperative period
Authors: Moodley S , Govender K
Published: January 2020

Background: Doctors complete death notification forms poorly, in South Africa and globally. This reduces accuracy of mortality statistics in South Africa, which is needed by policymakers and clinicians to focus on healthcare improvement initiatives. The law on procedure-related deaths was changed in 2008, directly informing on the practice of anaesthesiologists. Perioperative deaths continue to be misclassified, possibly related to doctors’ lack of knowledge or understanding of the law. This study aimed to determine if perioperative clinicians working in theatre and the Intensive Care Unit (ICU) knew and understood the law pertaining to deaths in the perioperative period.

Method: A survey was conducted at eight hospitals in the Durban area amongst specialists and non-specialists who work in theatre and ICU. The questionnaire had three parts: definitions, medico-legal experiences and clinical scenarios.

Results: Eighty responses were received, a response rate of 74%. More non-specialists responded (57%). When undecided on how to classify a death, clinicians mostly seek assistance from their private medico-legal insurance or a senior colleague. However, specialists are unable to define or classify unnatural and procedure-related deaths any better than non-specialists.

Conclusion: Specialist and non-specialist knowledge and application of the law relating to unnatural deaths in the perioperative period is poor. Forensic pathologist assistance is underutilised. More needs be done to empower doctors on medico-legal issues affecting perioperative clinical practice.

Published: January 2020

Dünyada nüfus artışı ile birlikte
sosyo-ekonomik değişmelerin sonucunda, insan ihtiyaçlarının, alışkanlıklarının
ve zevklerinin değişmesi tüketim yapısını da değiştirmiştir. Özellikle tarımsal
ve hayvansal ürünlere dayalı gıda ürünlerinde bu değişim kendini daha fazla
göstermektedir. Son yıllarda bu ürünlerdeki taklit ve tağşişin artması,
tüketicilerin bilinçlenmesine neden olmuştur. Bu da tüketicilerin nispeten daha
doğal olduğunu düşündüğü yöresel ürünlere yönelmelerine ve satın almada öncelik
verdiklerini göstermektedir.

Bu çalışmada tüketicilerin yöresel
ürünlerde satın almayı etkileyen faktörler konusundaki değerlendirmelerini ve
bu değerlendirmelerin tüketicilerin sosyo-demografik özelliklerine göre
farklılaşıp farklılaşmadığını tespit etmek amaçlanmıştır. Veriler anket yöntemi
kullanılarak, Siirt il merkezinde yaşayan tüketicilerden toplanmıştır. Çalışma
sonucunda, tüketicilerin genel anlamda yöresel ürün pazarında faaliyet gösteren
perakendeci işletmelerin satın almada dürüst davranış sergilemeleri konusunda
olumlu değerlendirmelere sahip oldukları ve bu değerlendirmelerin cinsiyet,
meslek ve gelir durumlarına göre farklılık gösterdiği; öğrenim, yaş ve medeni
duruma göre ise farklılık göstermediği tespit edilmiştir.

Nonlinear Estimation of Similarity Among Scientists’ Disciplinary Profiles. A Case Study
Authors: Osińska Veslava , Sokolov Oleksandr , Mreła Aleksandra
Published: January 2020

Purpose/Thesis: Authors estimate the disciplinary similarity of researchers according to selected academic units with a different cross-section of specializations. The paper presents the model for studying disciplinary diversity of scientific units. The premise of the article is that knowledge of di­sciplinary profiles of researchers can be applied to create interdisciplinary teams, or one disciplinary team with a focused specializations.Approach/Methods: The approach is based on the visualization and comparison of disciplinary space and space of co-authorship. Fuzzy logic and aggregation norm were used to calculate disciplinary weights of each journal listed in the database. For visualization, new, dimension reduction algorithm t-SNE was applied. Achieved results were verified by using the expert’s knowledge.Results and conclusions: In the evaluation of scientific collaboration, a co-authorship relationship can be complemented by researchers’ disciplinary profiles represented by aggregation norm. Thanks to the continuity of researchers’ publishing activity, the proposed measure based on the disciplinary profile is stable.Research limitations: The sample of both selected teams and journals database is limited. The journals from WoS/Scopus list were considered because analyzed researchers publish articles there. Additionally, during linking these two databases, problems of matching journals titles appeared.Practical implications: The authors proposed a model of evaluating scientists’ disciplinary similarity and further, to estimate the potential of their collaboration.Originality/Value: This approach applies fuzzy logic algorithms to quantifying scientific interests and is another rare instance of practical application of artificial intelligence algorithms (fuzzy logic) in scientometric studies.
The Evolution of Researchers’ Bibliography: From Systematic Organization to Citation
Authors: Couzinet Viviane , Marteleto Regina , Thiesen Icléia
Published: January 2020

Purpose/Thesis: This paper analyses the publications of two authors from different countries through a number of citations identified by Google Scholar. Jean Meyriat and Edson Nery da Fonseca are outstanding researchers in France and Brazil, respectively, both contributing to the formation and advancement of information science in their countries. The “traditional” bibliography and the development trajectory of their scientific achievements were considered in this analysis.Approach/Methods: The analysis of the researchers’ publications identified by Google Scholar based on their names helps to understand the role that search engines play in the evaluation of science and its effect on information seeking and in the evaluation of the scientific production. The qualitative research is based on a bibliological analyses focusing on the way in which the written production of the selected authors is reported and highlighted. The carried out study is exploratory in nature, so it proposes to raise questions and to emit hypotheses that could suggest directions for further research.Results and conclusions: The uniformity of controlled metadata used in traditional bibliographies make it possible to follow the progress of an author’s thought. The same is true of other activities he has performed in and out of the field and, it is also true for what has been produced about this author. Searching for information in Google Scholar can show a researcher’s production and publi­cations about her/him in the order of citations but not in the order of the progress of the researcher’s scientific achievements or development of research focused on these achievements. Placed in the context of the analysis of the scientific field as it was defined by Bourdieu (1976), the observation of the visibility of the production Jean Meyriat and Edson Nery da Fonseca, two major actors in information science in France and Brazil , by Google Scholar, shows a tendency to underemphasize the role they played.Practical implications: The functioning of the scientific field has specific effects on the production of research. The search engines such as Google Scholar, made the research output more accessible on Internet. However, the criteria they prioritize, i.e., the number of citations, ignores important aspects of a scientific career. Qualitative analysis that considers the networks of sociability and the development trajectory of researchers’ scientific achievements may reveal relevant contributions to their scientific field.
Jak być kochaną. Kulturowe zapośredniczenie traumy wojennej w filmach z lat 60.
Authors: Łysak Tomasz
Published: January 2020

Teoria traumy pojawiła się w latach 90. jako wyraz rozczarowania tekstową orientacją dekonstrukcji i poststrukturalizmu. Jej celem było zwrócenie teorii ku światu. Jednakże w latach 60. polscy filmowcy z zapałem przedstawiali traumy wojenne, jak też ich echa. Przyłożenie narzędzi teoretycznych teorii traumy do trzech filmów: Dziś w nocy umrze miasto Jana Rybkowskiego (1961), Jak być kochaną Wojciecha Jerzego Hasa (1962) i Pasażerki Andrzeja Munka i Witold Lesiewicza (1963) ma trzy cele: ocenę poziomu rozumienia efektów wojennych stresorów traumatycznych w latach 60., odróżnienie uznawanych form przeżycia/śmierci od psychologicznego zranienia, które nie jest godne upamiętniania, a także potraktowanie kulturowych przedstawień traumy jako symptomów szerszych procesów kulturowych i społecznych.
„Heritage is Dead! Long Live Heritage!” Kino brytyjskie w obliczu kryzysu politycznego
Authors: Korczarowska Natasza
Published: January 2020

Kryzysy polityczne prowokują do stawiania pytań o przeszłość i ufundowaną na niej tożsamość. Niepewne jutro kieruje nas ku historii, w której próbujemy znaleźć potwierdzenie naszego stabilnego (narodowego) „my”. To, kim jesteśmy, wyrasta z nostalgii za przeszłością – pod warunkiem jednak, że owa przeszłość powraca w formie narracji kompensacyjnych. Zrealizowane na Wyspach po 2016 r. dzieła potwierdzają tezę Pierre’a Sorlin, że filmy historyczne dostarczają wiedzy wyłącznie na temat okresu, w którym powstały. Manifestuje się w nich zainteresowanie tymi momentami historii, które okazały się znaczące dla losów nie tylko Wielkiej Brytanii, lecz także całej Europy. Strategie realizowane przez  kino „po Brexicie” przywołują w pamięci ideologiczne spory z epoki rządów Margaret Thatcher skoncentrowane wokół  heritage cinema. Ale czy międzynarodowe sukcesy brytyjskich „filmów o przeszłości” (Dunkierka, Czas mroku, Faworyta) pozwalają spojrzeć na Brexit jak na „pożyteczną katastrofę” i przywołać głoszone w okresie thatcheryzmu hasło Brytyjczycy nadchodzą (lub Up your bum)?
Cztery historie filmowe z miastem w tle. O berlińskim obliczu transformacji w kinie niemieckim
Authors: Fiuk Ewa
Published: January 2020

Fiuk odnosi się do transformacji ustrojowej lat 1989 i 1990 w Niemczech i spogląda na nią przez pryzmat filmowego obrazu Berlina, zarówno w porządku chronologicznym (okres przed, podczas i po transformacji), jak i estetyczno-autorskim (osobisty styl autorów, ich przynależność generacyjna, pochodzenie). Spośród wielu filmów poświęconych Berlinowi wybiera cztery, które – jej zdaniem – wyraźnie i w ciekawy sposób oddają atmosferę towarzyszącą transformacji, jej przebieg bądź konsekwencje, a także zaświadczają o specyficznym i różnorodnym charakterze miasta, będącego miejscem akcji, oraz o zmianach, które nastąpiły w nim od czasów zimnowojennych do dziś, w tym zmianach w jego wizerunku medialnym. Produkcje, do których nawiązuje autorka, to: Coming out (1989, reż. Heiner Carow), Niebo nad Berlinem (Der Himmel über Berlin, 1987, reż. Wim Wenders), Good bye, Lenin! (2003, reż. Wolfgang Becker) i Oh, Boy! (Oh Boy, 2012, reż. Jan-Ole Gerster).
Perturbacje kinematografii słoweńskiej
Authors: Guštin Maša
Published: January 2020

Słoweńska kinematografia rozwinęła się wyraźnie po 1945 r., kiedy socjalistyczne państwo rozpoczęło budowę struktur nowej kinematografii jugosłowiańskiej, a KC ZKJ decydował o wszystkim, co dotyczyło świata filmowego. W latach 50. i 60. pod skrzydłami studia Triglav Film powstało wiele obrazów, które odniosły sukces i dziś uważane są za klasyki filmu słoweńskiego. Kinematografia słoweńska przeżywała w owym czasie odrodzenie na płaszczyźnie instytucjonalnej: w Lublanie działała Kinoteka, wychodził magazyn filmowy „Ekran”, został otwarty Wydział Reżyserii Filmowej i Telewizyjnej, powstało Słoweńskie Archiwum Filmowe. W latach 70. w filmach widać krytykę społeczną oraz problematykę jednostki znajdującej się na krawędzi upadku. Lata 80. to ciężki kryzys ekonomiczny i polityczny; pojawiają się także kasety wideo konkurujące z filmami hollywoodzkimi i programami telewizyjnymi. Tym niemniej powstaje wówczas pierwszy „niezależny” film zrealizowany poza głównymi strukturami produkcyjnymi, punkt przełomowy w liberalizacji słoweńskiej kinematografii. Po uzyskaniu niepodległości Republika Słowenii przejmuje odpowiedzialność za subwencjonowanie produkcji filmowej, którą w dużej mierze tworzy nowe pokolenie reżyserów, skupione na problematyce współczesności i okresu transformacji.

Factores que influyen en la incorporación de las Tecnologías de la Información y la Comunicación en universidades públicas: una aproximación desde la autopercepción docente
Authors: Zempoalteca Beatriz , González Juan , Barragán Jorge , Guzmán Teresa
Published: January 2020

La incorporación de las Tecnologías de la Información y la Comunicación (TIC) aún no se percibe consolidada en la praxis pedagógica en las Instituciones de Educación Superior (IES). La presente investigación identifica factores que influyen en la incorporación de las tic tomando en consideración la autopercepción de docentes adscritos a carreras del área de Ciencias Administrativas de IES públicas. El estudio fue realizado por medio de un método cuantitativo-descriptivo correlacional, con una técnica de encuestas. Se encontró que existen factores internos y externos que favorecen la incorporación de las nuevas tecnologías por parte de la docencia, que resultan de interés para el desarrollo de políticas institucionales sobre la formación del profesorado en las TIC.
La Responsabilidad Social de la Educación Superior como Bien Común. Concepto y desafíos
Authors: Martí Noguera Juan José , Licandro Óscar , Gaete Quezada Ricardo
Published: January 2020

Este artículo atiende al planteamiento de la Unesco de considerar como bien común a la Educación Superior, en un momento en que las Instituciones de Educación Superior están inmersas en procesos caracterizados por una progresiva mercantilización del conocimiento que condiciona el acceso a la financiación por posicionamiento en rankings internacionales, poniendo en riesgo el objeto de contribuir a un desarrollo sostenible en sus contextos. Mediante un particular análisis de aspectos relacionados con la Responsabilidad Social y la relación con los grupos de interés, se realiza una contribución a la reflexión teórica y a los desafíos para conceptualizar la Educación Superior como un bien común.
