Proliferasi In Vitro Plb Anggrek Dendrobium lasianthera Hasil Induksi Mutasi Genetik dengan Kolkisin Melalui Penambahan Benzyl Adenine
Authors: Bawonoadi Gilar , Wiendi Ni Made Armini , Krisantini .
Published: June 2018

Dendrobium lasianthera merupakan spesies anggrek yang endemik di Papua. Proliferasi atau perbanyakan tanaman melalui kultur jaringan merupakan salah satu alternatif dalam memperbanyak spesies tanaman dengan jumlah individu yang terbatas. Keragaman karakteristik pada tanaman hias, baik yang bersifat alami atau hasil dari induksi mutasi, dianggap penting dalam menentukan nilai ekonomisnya. Pengembangan protokol produksi membutuhkan penelitian terkait media yang sesuai untuk memperbanyak tanaman. Penelitian dilakukan dengan mengkulturkan eksplan anggrek Dendrobium lasianthera berupa plb (protocorm-like body) dari anggrek D. lasianthera yang telah diinduksi mutasi melalui perendaman dalam larutan mutagen kolkisin pada penelitian sebelumnya. Pengamatan dilakukan terhadap kemampuan pertumbuhan 960 eksplan dari 16 kombinasi perlakuan (termasuk kontrol) perendaman kolkisin ditumbuhkan pada media MS0 yang ditambahkan sitokinin BA (6-Benzyladenine) sebanyak 1 mgL-1 dan 2 mgL-1. Hasil penelitian menunjukkan bahwa eksplan dengan kombinasi perlakuan perendaman yang berbeda memiliki kemampuan pertumbuhan yang berbeda secara nyata, dilihat dari jumlah daun, akar, plb dan tunas baru yang terbentuk selama periode pengamatan.Perbedaan dalam konsentrasi BA dalam media tidak menunjukkan respon yang berbeda nyata dalam jumlah daun dan akar baru yang terbentuk, namun nyata meningkatkan jumlah tunas baru yang terbentuk dan mempercepat pembentukan tunas. Eksplan yang ditumbuhkan pada media BA 1 mgL-1 memiliki rata-rata waktu awal pembentukan tunas yang lebih singkat dibandingkan dengan media BA 2 mgL-1. Beberapa planlet hasil induksi mutasi menunjukkan perbedaan fenotipe dari planlet kontrol berupa bentuk daun yang berbeda.

Memoria en Arendt, olvido en Nietzsche y su relación con la promesa. Soluciones al problema de la acción y su relación con los orígenes del Derecho Penal
Authors: Barnes Débora Vanesa Clara
Published: June 2018

El presente artículo analiza el tópico de la memoria en Arendt, del olvido en Nietzsche, y su relación con la promesa, como formas de brindar solución al problema de la acción del hombre en el contexto de sociedad o comunidad que es, precisamente, el contexto del desarrollo humano, el que históricamente remite a prácticas comunitarias signadas por la violencia, así como a la génesis del Derecho Penal y del concepto de Justicia. No obstante, aunque algunos autores se han ocupado de señalar similitudes y diferencias entre el pensamiento de Arendt y Nietzsche, en orden a la promesa y su relación con la memoria y el olvido, no lo han hecho en referencia al Derecho, trabajo que resulta necesario realizar a través del presente artículo. En orden a ello, el estudio se centra en el pensamiento contenido en el Capítulo V de La Condición Humana y posee breves remisiones a los Capítulos I y II de la obra citada, en función del contenido del Tratado Segundo de La Genealogía de la Moral, sin perjuicio del recurso a otras fuentes con contribuciones en el tema estudiado.
McLuhan y las estructuras de la experiencia El caso del alfabeto y el espacio euclidiano
Authors: Carrillo Canán Alberto J. L.
Published: June 2018

Marshall McLuhan forma parte del conjunto de teóricos que de una u otra manera ponen el acento en lo que en sentido estricto, con base en la tradición kantiana, puede ser llamado las estructuras de la experiencia. En términos kantianos las estructuras de la experiencia no son otra cosa que las condiciones de posibilidad de los objetos de la experiencia, es decir, de los fenómenos. Entre otros, E. Husserl, M. Heidegger, E. Durkheim, E. T. Hall, M. Foucault, por mencionar solamente a algunos teóricos además de McLuhan, trabajan con la idea de las estructuras de la experiencia, aislando unas, proponiendo otras y utilizando diferentes terminologías para nombrarlas. En este texto nos concentraremos en el caso de McLuhan. De hecho, las tres épocas mediáticas en la historia de la humanidad distinguidas por McLuhan, a saber, la época “aural oral”, la época “mecánica” y la época “eléctrica”, corresponden cada una a estructuras de la experiencia bien definidas. Podemos decir que la teoría mediática de McLuhan consiste en investigar qué estructuras de la experiencia genera cada medio o combinación de ellos. A fin de cuentas, lo que en ocasiones ha sido considerado un “reduccionismo tecnológico” en McLuhan no es otra cosa que la idea de que los medios dan las condiciones de posibilidad de los objetos de la experiencia. Los medios definen la fenomenalidad o estructura de los fenómenos, es decir, los medios definen la manera en la que experimentamos la realidad. Por eso, “el medio es lo que cuenta”, que es la traducción correcta de la famosa frase de McLuhan the medium is the message. La ventaja de esta aproximación protokantiana a la teoría de que “el medio es lo que cuenta”, es que permite traducir esta noción básica mcluhaniana y la teoría correspondiente a un modelo teórico más claro que el ofrecido por el propio McLuhan, lo que a la vez permite establecer más fácilmente conexiones y diferencias con teóricos tales como Durkheim, Heidegger o Foucault. En este texto nos concentraremos en el espacio euclidiano como forma de la experiencia condicionada por la escritura con base en el alfabeto fonético. 
La errancia como método: la noche de Jacques Rancière
Authors: Rossi María José
Published: June 2018

Tal como se desprende de La Nuit des prolétaires (1981) y de La methode de l’égalité (2012), el método de lectura e investigación de Jacques Rancière encuentra en la inmanencia su principio rector fundamental. El presente trabajo despliega este principio, lo desancla de los planos de referencia y trascendencia, y lo relaciona con el quehacer de la conciencia en el trayecto fenomenológico hegeliano. El objetivo es proveer un derrotero posible a la hermenéutica de la inmanencia del barroco latinoamericano: una lectura de la errancia en el que cada objeto reclama ser interrogado por sí mismo, en el que las palabras son sus propios ecos, y las escenas montajes dispuestos para ser vistos y oídos

The Serendipity of Anthropological Practice
Authors: Martinez Francisco
Published: June 2018

Is fieldwork as anthropologists do it simply a method among others? This article disagrees, drawing on the concept of “serendipity” as introduced by German scholar Ina-Maria Greverus. Beyond the prescribed way of any method, anthropology’s specificity articulates as “discovery”, in this case: an unexpected discovery of remains of the Soviet past in Estonia, through the author’s family life.

With reference to anthropologist Ina-Maria Greverus’ pioneering analyses of human-environment relations since the 1970s, the article pushes the idea of Heimat further to the more processual concept of Beheimatung. This is especially relevant for an anthropology of the transnational worlds of (post-)migrant societies with their current negotiation of cross-border migration in the present and concerning colonial objects from the past in museums.
The Eurozone Crisis, Greece and European Integration

Published: June 2018

Around 2010, a shift in the EU-understanding of austerity took place – from a future-orientated vision based on concepts of solidarity, cohesion and subsidiarity, to a crisis-driven present shaped around the imperatives of immediate fiscal discipline and debt repayment. This has had contradictory effects, producing widespread divisions, disunity and rising nationalism across Europe on one hand, and new forms of social solidarity and resistance on the other.

Authors: Bozoudis Michail , Lappas Ilias , Kottas Angelos
Published: June 2018

The development of an aircraft maintenance planning optimization tool and its application to an aircraft component is presented. Various reliability concepts and approaches have been analyzed, together with objective criteria which can be used to optimize the maintenance planning of an aircraft system, subsystem or component. Wolfram® Mathematica v10.3 9 (Witney, UK) has been used to develop the novel optimization tool, the application of which is expected to yield significant benefits in selecting the most appropriate maintenance intervention based on objective criteria, in estimating the probability of nonscheduled maintenance and in estimating the required number of spare components for both scheduled and nonscheduled maintenance. As such, the results of the application of the tool can be used to assist the risk planning process for future system malfunctions, providing safe projections to facilitate the supply chain of the end user of the system, resulting in higher aircraft fleet operational availability.

Published: June 2018

The use of biological control agents (BCAs) is of interest within an integrated management strategy of Verticillium wilt of olive (VWO) caused by the soil-borne fungus Verticillium dahliae Kleb. Previous studies have shown that the root/rhizosphere of healthy olive plants is an important reservoir of microorganisms displaying biocontrol activity against VWO (i.e., Pseudomonas strains PICF7 and PIC141). Moreover, these BCAs are already adapted to the ecological niche where they are deployed. Three novel bacteria (strains PIC28, PIC73 and PIC167) from nursery-produced olive plants were in-depth characterized using a previously implemented approach consisting of in situ isolation, in vitro antagonism tests, in planta bioassays, phenotypic and metabolic characterization, genome analyses and in silico identification of traits involved in plant-bacteria interactions, and multi-locus sequence analyses. All strains displayed in vitro growth inhibition of different olive pathogens and biocontrol effectiveness against Verticillium dahliae, with strain PIC73 being the most effective BCA. Strains PIC73 and PIC167 were identified as Paenibacillus polymyxa (Prazmowski) Ash et al. and Paenibacillus terrae Yoon et al., respectively. Strain PIC28 belongs to the Bacillus genus. Some of these Bacillales members showed in vitro compatibility with previously characterized BCAs (Pseudomonas spp. strains) also originating from the olive rhizosphere, paving the way for the future development of tailored bacterial consortia effective against VWO.
Alterations in Metabolic Status and Headshaking Behavior Following Intravenous Administration of Hypertonic Solutions in Horses with Trigeminal-Mediated Headshaking
Authors: Sheldon Shara , Aleman Monica , Costa Lais , Santoyo A. Cristina , Howey Quinn , Madigan John
Published: June 2018

Trigeminal-nerve-mediated headshaking represents a major welfare challenge for owners and veterinarians and is caused by a low threshold firing of the trigeminal nerve resulting in pain manifested as violent head jerking that often terminates the horse’s career and life due to poor quality of life and suffering. As metabolic changes such as acid–base status and electrolytes play a role in nerve firing, this study sought to assess the effects following administration of hypertonic solutions on headshaking behavior in affected horses. This prospective randomized controlled crossover design utilized six horses affected with trigeminal-mediated headshaking and three treatment groups receiving intravenous administration of 5% dextrose solution at 2 mL/kg bwt (DS), NaCl 7.5% at 4 mL/kg bwt (HS), or NaHCO3 8.4% at 2 mmol/kg bwt (HB). Horses were assessed for headshaking behavior changes at times T0 (baseline, before infusion) and T15, 30, 60, 120 min post infusion. Venous blood variables: pH, HCO3−, standard base excess (SBE), Na+, Cl−, K+, Ca2+, Mg2+, total magnesium (tMg), glucose, and lactate were measured at T0 (baseline, before infusion) and T5, 15, 30, 60, 120 min post infusion. Strong ion difference (SID) and anion gap (AG) were calculated for each time point. With HB treatment, there was greater than 50% reduction in headshaking rate. There was an effect of time on increasing headshaking rate. There was an effect of breed on headshaking rate. Changes in blood parameters following DS were virtually absent. Infusion of HS caused mild changes and did not vary much from baseline except for SID and AG. Only infusion of HB caused blood pH and HCO3− to be outside of the physiologic range (alkalemia and metabolic alkalosis, respectively), SBE to double or triple, AG to decrease, and SID to increase compared to baseline. Infusion of DS was followed by increase in blood glucose and decrease in blood Na+. Infusion of HS was followed by increase in Na+ and Cl− and decrease in Mg2+. Infusion of HB was followed by decrease in Mg2+. Blood tMg, K+, and Ca2+ decreased slightly, but did not vary greatly from baseline following any of the treatments, remaining within physiologic ranges. Changes in blood composition were transient. Among all treatments, only HB had an effect on headshaking rate. The limited effects following these fluids were likely due to normal mechanisms of regulation of blood levels of pH and electrolytes. Further investigations of changes in electrolytes that might affect nerve firing should be explored.

Authors: Castiglione Dora , Platania Armando , Conti Alessandra , Falla Mariagiovanna , D’Urso Maurizio , Marranzano Marina
Published: June 2018

Background: Dietary vitamins and minerals are essential compounds for the proper functioning of metabolic enzymes, regulation of gene transcription, and powering the body’s defense against oxidative stress. The aim of the present study was to investigate micronutrient consumption separately by age and sex, major dietary sources, and percentage of individuals meeting the recommended requirements according to Italian (Livelli di Assunzione di Riferimento di Nutrienti (LARN)) and European (European Food Safety Agency (EFSA)) agencies. Methods: Data were obtained from the Mediterranean Healthy Eating, Ageing, and Lifestyle (MEAL) study, which included a sample of 1838 individuals randomly collected in the city of Catania, southern Italy. A validated food frequency questionnaire was used to collect information on diet. Results: Intake of vitamin A, vitamin C, and vitamin B group (except vitamin B9) was in line with other reports and was adequate according to the guidelines, while the percentage of individuals meeting the guidelines for vitamin D, vitamin E, and vitamin B9 was about 3%, 10%, and 40%, respectively. Among minerals, intake of iron, magnesium, and selenium was adequate for most of the sample, while the percentage of individuals meeting the recommendations for calcium, sodium, and potassium intake was about 20%, 8%, and 35%, respectively. Conclusions: An important percentage of the population would benefit from campaigns raising awareness of micronutrient deficiency or excessive consumption potentially affecting their health.
Evaluation of Ultrasonic Bonding Strength with Optoacoustic Methods
Authors: Kamimura Takumi , Yoshida Sanichiro , Sasaki Tomohiro
Published: June 2018

This study reports the application of an optoacoustic method for evaluating the bonding strength of ultrasonically bonded joints in a non-destructive and non-contact fashion. It is proposed that the bonding strength is correlated with the resonant frequency of bonded joints. The bonding strength measured with a destructive tensile test roughly increased with the vibration time, however, it varied, causing the transitional and dispersed formation of micro-bonds at the bonding interface. Scanning Electron Microscopic observation of the fractured surface suggested that the bonding strength depends on the total bonded area of micro-bonds. Frequency response of the bonded joint was examined with a non-destructive method using a piezo-electric vibrator. The experiment revealed that the resonant frequency exponentially increased with the bonding strength. In addition, this vibration behavior was dynamically visualized with electronic speckle pattern interferometry (ESPI). The correlation between the bonded area and the resonant frequency is discussed based on finite element analysis. The results indicate the possibility for in-situ evaluation of the ultrasonic bonding strength.
A UAV-Based Visual Inspection Method for Rail Surface Defects
Authors: Wu Yunpeng , Qin Yong , Wang Zhipeng , Jia Limin
Published: June 2018

Rail surface defects seriously affect the safety of railway systems. At present, human inspection and rail vehicle inspection are the main approaches for the detection of rail surface defects. However, there are many shortcomings to these approaches, such as low efficiency, high cost, and so on. This paper presents a novel visual inspection approach based on unmanned aerial vehicle (UAV) images, and focuses on two key issues of UAV-based rail images: image enhancement and defects segmentation. With regards to the first aspect, a novel image enhancement algorithm named Local Weber-like Contrast (LWLC) is proposed to enhance rail images. The rail surface defects and backgrounds can be highlighted and homogenized under various sunlight intensity by LWLC, due to its illuminance independent, local nonlinear and other advantages. With regards to the second, a new threshold segmentation method named gray stretch maximum entropy (GSME) is presented in this paper. The proposed GSME method emphasizes gray stretch and de-noising on UAV-based rail images, and selects an optimal segmentation threshold for defects detection. Two visual comparison experiments were carried out to demonstrate the efficiency of the proposed methods. Finally, a quantitative comparison experiment shows the LWLC-GSME model achieves a recall of 93.75% for T-I defects and of 94.26% for T-II defects. Therefore, LWLC for image enhancement, in conjunction with GSME for defects segmentation, is efficient and feasible for the detection of rail surface defects based on UAV Images.

Published: June 2018

This study was initiated to evaluate the performance of asphalt binders and mixtures incorporating linear low-density polyethylene- calcium carbonate (LLDPE-CaCO3) pellet, either with or without titanate coupling agent. The detailed manufacturing process of modifier pellets was displayed. The coupling agent was used to enhance the cross-linking between materials by means of winding up covalent bonds or molecule chains, thus improving the performance of composites. In the preparation of modified bitumen, the preheated asphalt binder was mixed with the modifiers using a high shear mixer at 5000 rpm rotational speed for 45 min. Experimental works were conducted to evaluate the performance of asphalt binders in terms of volatile loss, viscosity, rutting potential, and low temperature cracking. Meanwhile, the asphalt mixtures were tested using the flow number test and tensile strength ratio (TSR) test. The addition of LLDPE-CaCO3 modifiers and coupling agent does not significantly affect the volatile loss of modified asphalt binders. The addition of modifiers and coupling agent has significantly improved the resistance to permanent deformation of asphalt binders. Even though, the addition of LLDPE-CaCO3 modifier and coupling agent remarkably increased the mixture stiffness that contributed to lower rutting potential, the resistance to low temperature cracking of asphalt binder was not adversely affected. The combination of 1% coupling agent with 3% PECC is optimum dosage for asphalt binder to have satisfactory performance in resistance to moisture damage and rutting.
Study on the Mechanism of the Variable-Speed Rotor Affecting Rotor Aerodynamic Performance
Authors: Xie Jiayi , Guan Nanxiang , Zhou Ming , Xie Zhifeng
Published: June 2018

The variable-speed rotor has proven to be a promising means to improve helicopter performance. Previous investigations on the aeromechanics of the variable-speed rotor are scarce. This work studies the mechanism of the variable-speed rotor affecting the rotor aerodynamic performance by means of dimensionless parameter analysis and reveals the various effect mechanisms under the various flight speeds and take-off weights. The current work shows that, during hover, the variable-speed rotor improves the rotor aerodynamic performance by reducing the blade dynamic pressure, while the non-uniform thrust distribution is attributed to the reduced rotor speed suppresses the performance improvement. In slow forward flight, the blade dynamic pressure reduction improves the rotor aerodynamic performance. In cruise and fast forward flight, both the blade dynamic pressure and advancing blade tip compression loss reductions improve the rotor aerodynamic performance. The study also shows that in forward flight, the rotor loading is smaller, and the effect of reducing the advancing blade tip compression loss through the variable-speed rotor is greater.

Various types of amine-functionalized silica/organosilica membranes have been developed due to their potentially superior CO2 separation performance. This article reviews the progress made in this field and special attention is paid to elucidating the role of amine type in CO2 separation performance within amine-functionalized silica/organosilica membranes. This review includes a systematic comparison of various organosilica membranes with either unhindered or sterically hindered amines developed in our previous studies. Herein, we thoroughly discuss the structural characterizations and CO2 adsorption/desorption properties of amine-functionalized xerogel powders and CO2 transport/separation performance across the relevant membranes. Future directions for the design and development of high-performance CO2 separation membranes are suggested, and particular attention is paid to the future of activation energies for gas permeation.

Published: June 2018

As one of the typical cyber physical systems (CPS), the user energy management system (UEMS) plays an increasingly significant role in the smart grid, such as participating in automated demand response (ADR). Traditional analyses related to the UEMS in ADR programming mainly focus on energy management strategies or algorithms, where the interdependence and interplay between the cyber system and the physical system is neglected. This paper firstly presents an ADR control strategy of the UEMS with the objective of minimizing electricity bills and meeting users’ comfort constraints. Then, a hybrid scheme including Message Queuing Telemetry Transport (MQTT) and Message Queuing Telemetry Transport for Sensor Network (MQTT-SN), which are publish-subscribe communication protocols, is developed to establish the cyber system of the UEMS. To evaluate the cyber-physical performance of the UEMS in ADR programs, the hybrid dynamic models of major behaviors of the UEMS are proposed and a UPPAAL (http://www.uppaal.org/)-based methodology of the formal specification and verification is also proposed. In case studies, the impact of communication reliability on the proposed ADR control strategy is studied and the quality of service (QoS) mechanism provided by MQTT/MQTT-SN is demonstrated as a cost-effective solution for the ADR control strategy under unreliable communication.

A record-breaking dust episode took place in Crete on 22 March 2018. The event was characterized by surface concentrations exceeding 1 mg m−3 for a period of 4–7 h, reaching record values higher than 6 mg m−3 at the background station of Finokalia. We present here a detailed analysis of the atmospheric dynamical processes during this period, to identify the main reasons for such extreme dust advection over Crete. At the synoptic scale, the weakening of the polar vortex and the meridional transport of polar air masses at upper tropospheric layers resulted in a strong jet streak over north Africa and Central Mediterranean and corresponding tropospheric folding that brought cold stratospheric air in mid and upper troposphere. Cyclogenesis occurred at the Gulf of Sirte in Libya, resulting in strong winds over the north-east parts of Libya, enhancing particle emissions. The dust plume traveled at low altitude (0.5–3 km) along the warm conveyor belt preceding the depression cold front. This type of dusty southerly wind is commonly known as “Khamsin”. As the flow approached Crete, Foehn winds at the lee side of the island favored the downward mixing of dust towards the surface, resulting in local maxima of PM10 in Heraklion and Finokalia. The analysis is based on the combination of high-resolution WRF-Chem simulations reaching up to 1 × 1 km grid space over Crete, ground-based and satellite remote sensing of the dust plumes (PollyXT LiDAR, MSG-SEVIRI, MODIS) and detailed surface aerosol in situ measurements at urban (Heraklion, Chania, Greece) and background (Finokalia) stations in Crete.

Published: June 2018

Synthesis of activated carbon from waste biomass is of current interest towards sustainability. The properties of biomass-derived activated carbon largely depend on the carbonization process. This study reports the preparation of mesoporous activated carbon with extremely high surface area from hemp bast fiber using hydrothermal processing. Hot water processing (390–500 °C) followed by activation using KOH and NaOH was investigated at different mass ratios. The described approach was found to enhance the mesoporosity (centered at 3.0 to 4.5 nm) of the hemp-derived activated carbon (HAC) from activation [confirmed by BJH (Barrett-Joyner-Halenda) pore size distribution and TEM (transmission electron microscopy) imaging]. BET (Brunauer-Emmett-Teller) results showed that the product has an extremely high surface area (2425 m2/g) while the surface functional groups (–OH, –COOH, C=C/C–C) were confirmed by FTIR (Fourier transform infrared spectroscopy) and further quantified by XPS (X-ray photoelectron spectroscopy). Increasing KOH concentration was found to enhance the surface area with a maximum biochar-to-KOH (g/g) ratio of 1:3. The crystallite domain size of HAC was determined using Raman spectroscopy of different wavelengths. The procedure described in this study is an environmentally friendly scalable route for the mass production of activated carbon using hemp fiber.
Observation of Hybrid MAPbBr3 Perovskite Bulk Crystals Grown by Repeated Crystallizations
Authors: Chen Lung-Chien , Lee Kuan-Lin , Lin Shao-En
Published: June 2018

In this study, the inverse temperature crystallization method was used to produce bulk crystal CH3NH3PbBr3 (MAPbBr3) perovskite, and repeated crystallization processes were carried out to obtain a larger crystal size and develop a bulk material for application in semiconductor devices. The material and optoelectronic properties of the MAPbBr3 perovskite crystals after the repeated processes were characterized. The X-ray diffraction (XRD) patterns of all samples demonstrated a pure perovskite phase. One strong diffraction peak located at 29.4°, which corresponds to the (200) perovskite plane, was observed after the first growth cycle. The mobilities for the samples after the first, second, and third growth cycles were calculated and resulted to be 0.9, 5.6, and 54.7 cm2/Vs, respectively, according to Mott–Gurney law. A higher mobility after the multiple crystallization processes indicated that the surface states caused by voids in the crystals favored electron transition in the perovskite material.

Published: June 2018

Being aware of a personal context is a promising task for various applications, such as biometry, human-computer interactions, telemonitoring, remote care, mobile marketing and security. The task can be formally defined as the classification of a person being considered into one of predefined labels, which may correspond to his/her identity, gender, physical properties, the activity that he/she performs or any other attribute related to the environment being involved. Here, we offer a solution to the problem with a set of multiple motion sensors worn on the wrist. We first provide an annotated and publicly accessible benchmark set for context-awareness through wrist-worn sensors, namely, accelerometers, magnetometers and gyroscopes. Second, we present an evaluation of recent computational methods for two relevant tasks: activity recognition and person identification from hand movements. Finally, we show that fusion of two motion sensors (i.e., accelerometers and magnetometers), leads to higher accuracy for both tasks, compared with the individual use of each sensor type.

Published: June 2018

The rapid proliferation of sensors and big data repositories offer many new opportunities for data science. Among many application domains, the analysis of large trajectory datasets generated from people’s movements at the city scale is one of the most promising research avenues still to explore. Extracting trajectory patterns and outliers in urban environments is a direction still requiring exploration for many management and planning tasks. The research developed in this paper introduces a spatio-temporal framework, so-called STE-SD (Spatio-Temporal Entropy for Similarity Detection), based on the initial concept of entropy as introduced by Shannon in his seminal theory of information and as recently extended to the spatial and temporal dimensions. Our approach considers several complementary trajectory descriptors whose distribution in space and time are quantitatively evaluated. The trajectory primitives considered include curvatures, stop-points, self-intersections and velocities. These primitives are identified and then qualified using the notion of entropy as applied to the spatial and temporal dimensions. The whole approach is experimented and applied to urban trajectories derived from the Geolife dataset, a reference data benchmark available in the city of Beijing.
Econometric Fine Art Valuation by Combining Hedonic and Repeat-Sales Information
Authors: Galbraith John W. , Hodgson Douglas J.
Published: June 2018

Statistical methods are widely used for valuation (prediction of the value at sale or auction) of a unique object such as a work of art. The usual approach is estimation of a hedonic model for objects of a given class, such as paintings from a particular school or period, or in the context of real estate, houses in a neighborhood. Where the object itself has previously sold, an alternative is to base an estimate on the previous sale price. The combination of these approaches has been employed in real estate price index construction (e.g., Jiang et al. 2015); in the present context, we treat the use of these different sources of information as a forecast combination problem. We first optimize the hedonic model, considering the level of aggregation that is appropriate for pooling observations into a sample, and applying model-averaging methods to estimate predictive models at the individual-artist level. Next, we consider an additional stage in which we incorporate repeat-sale information, in a subset of cases for which this information is available. The methods are applied to a data set of auction prices for Canadian paintings. We compare the out-of-sample predictive accuracy of different methods and find that those that allow us to use single-artist samples produce superior results, that data-driven averaging across predictive models tends to produce clear gains, and that, where available, repeat-sale information appears to yield further improvements in predictive accuracy.
