EXPLORATION OF OPEN DATA IN SOUTHEAST ASIA TO GENERATE 3D BUILDING MODELS
Authors: Biljecki F.
Published: September 2020

Abstract. This article investigates the current status of generating 3D building models across 11 countries in Southeast Asia from publicly available data, primarily volunteered geoinformation (OpenStreetMap). The following countries are analysed: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Timor-Leste, and Vietnam. This cross-country study includes multiple spatial levels of analysis: country, town, and micro-level (smaller neighbourhood). The main finding is that authoritative data to generate 3D building models is almost non-existent while building completeness in OpenStreetMap is highly heterogeneous, yielding location-dependent conclusions. While in general just a fraction of mapped buildings has height information and none of the administrative areas provides sufficient information to generate 3D building models, on a micro-level some areas are fully complete, providing a high potential to generate 3D building models on a precinct scale, which may be useful for certain spatial analyses. Furthermore, some areas have high building completeness, requiring only half of the work necessary for the extrusion: the collection of building height attributes. As a part of this work, a semantic 3D building model of a selected set of buildings in Singapore has been generated and released as open data (CityJSON), and the developed code was open-sourced.

Abstract. This article presents a spatio-temporal web application dedicated to the co-exploitation of heterogeneous data spatialized in a common 3D environment, providing several paradigms for supporting their co-visualization and interactions within the 3D environment and across time. The relevance of this tool is demonstrated here with two use cases involving historians and sociologists with the common objective of better understanding the formation of the Parisian metropolis. The study focuses on the evolution of the city of Nanterre (Paris area), which underwent many changes in the 1950s, and in particular on shantytown areas. Through census as statistical data and aerial imagery as visual data, a group of historians and sociologists experimented the relevance of the joint exploitation of those heterogeneous data within the proposed spatio-temporal web application.
A SEMANTICALLY ENRICHED AND WEB-BASED 3D ENERGY MODEL VISUALIZATION AND RETRIEVAL FOR SMART BUILDING IMPLEMENTATION USING CITYGML AND DYNAMIZER ADE

Published: September 2020

Abstract. Smart Cities are complex distributed systems which may involve services, applications, sensors and IoT devices. In order to be able to link and use such heterogeneous data, spatial data infrastructures for Smart Cities can play an important role in establishing interoperability between systems and platforms. Semantic 3D city models describe spatial, graphical and thematic aspects of the city objects according to the CityGML international standard, issued by the Open Geospatial Consortium (OGC). The requirement to support energy time-dynamic properties within CityGML objects arises from the fact that cities yield great potential in terms of energy consumption reduction and efficiency increase. In order to support such time-varying energy properties concerning city objects, recent extensions of the CityGML in the form of Application Domain Extensions (ADEs) are researched and developed, such as the Energy ADE and the Dynamizer ADE. Starting from a Building Information Model (BIM) and evaluating energy use of the building through the created Building Energy Model (BEM), the aim of this study is to integrate and visualize the time-based energy simulation results with the 3D building model within a 3D semantic city model. Using the latter ADE, the highly detailed static 3D Building (LOD 4) is extended to support those energy variations of individual feature properties and associations over time. Moreover, the web-based visualization approaches and data retrieval were further researched, and an interoperable web-based application was developed, in order to accomplish an integrated knowledge on how time-series data can be distributed in a virtual 3D environment.
IMPACT OF INFORMATION MANAGEMENT DURING DESIGN & CONSTRUCTION ON DOWNSTREAM BIM-GIS INTEROPERABILITY FOR RAIL INFRASTRUCTURE
Authors: Floros G. S. , Ruff P. , Ellul C.
Published: September 2020

Abstract. The need for efficient and sustainable infrastructure – always critical to a city – is further gaining momentum as urbanisation creates the challenge of sustainably designing, constructing and operating the built environment. The AECOO industry, directly responsible for addressing this challenge, has adopted the use of BIM and GIS to aid in this endeavour. Both BIM and GIS overlap with respect to capturing aspects of the built environment, but are not interoperable by nature. To ensure a consistent and structured way of managing the information produced within these environments, industry standards such as IFC are implemented. Research to date focuses on addressing the integration between BIM and GIS for buildings by delving into the IFC and CityGML interoperability, which has highlighted significant geometric and semantic barriers that in the stage of integration, cannot be easily manoeuvred. The purpose of this paper is to provide an insight regarding the information lifecycle during Design & Construction in the HS2 Rail Infrastructure project and investigate the impact of current information management processes – and in particular Standards such as IFC, – on BIM-GIS interoperability and lifecycle management of an asset. Results demonstrate the levels of mis mapping during the export to IFC which varies depending on the infrastructure asset type. Discussion shows that these can be addressed by the introduction of additional semantic property sets to facilitate downstream BIM-GIS interoperability for O & M, enabling scope for future work.
EVALUATION OF MOBILE MAPPING SYSTEMS FOR INDOOR SURVEYS
Authors: Salgues H. , Macher H. , Landes T.
Published: September 2020

Abstract. With their high recording rate of hundreds of thousands of points acquired per second, speed of execution and a remote acquisition mode, SLAM based mobile mapping systems (MMS) are a very powerful solution for capturing 3D point clouds in real time, simply by walking in the area of interest. Regarding indoor surveys, these MMS have been integrated in handheld or backpack solutions and become fast scanning sensors. Despite their advantages, the geometric accuracy of 3D point clouds guaranteed with these sensors is lower than the one reachable with static TLS. In this paper the effectiveness of two recent mobile mapping systems namely the GeoSLAM ZEB-REVO RT and the more recent GreenValley LiBackPack C50 is investigated for indoor surveys. In order to perform a reliable assessment study, several datasets produced with each sensor are compared to the high-cost georeferenced point cloud obtained with static laser scanning target-based technique.
AUTOMATIC CONVERSION OF CITYGML TO IFC
Authors: Salheb N. , Arroyo Ohori K. , Stoter J.
Published: September 2020

Abstract. The trend of increased usage of both BIM and 3D GIS and the similarity between the two has led to an increase in the overlap between them. A key application of such overlap is providing geospatial context data for BIM models through importing 3D GIS-data to BIM software to help in different design-related issues. However, this is currently difficult because of the lack of support in BIM software for the formats and data models of 3D Geo-information. This paper deals with this issue by developing and implementing a methodology to convert the common open 3D city model data model into the most common open BIM data format, namely CityGML (Gröger et al., 2012) to IFC (buildingsmart, 2019b). For the aim of this study, the two standards are divided into 5 comparable subparts: Semantics, Geometry, Geographical coordinates, Topology, and Encoding. The characteristics of each of these subparts are studied and a conversion method is proposed for each of them from the former standard to the latter. This is done by performing a semantic and geometrical mapping between the two standards, converting the georeferencing from global to local, converting the encoding that the two standards use from XML to STEP, and deciding which topological relations are to be retained. A prototype implementation has been created using Python to combine the above tasks. The work presented in this paper can provide a foundation for future work in converting CityGML to IFC. It provides an insight into the relationship between the two standards and a methodology for the conversion from one to the other, and the process of developing software to perform such conversion. This is done in a way that can be extended for future specific needs.

Published: September 2020

Abstract. Visualization applications are an increasingly significant component in the field of 3D geo-information. In them, the utilization of consumer grade virtual reality (VR) head mounted displays (HMD) has become a topical research question. It is notable, that in most presented implementations, the VR visualization is accomplished by a game engine. As game engines rely on textured mesh models as their conventional 3D asset format, the challenge in applying photogrammetric or laser scanning data is in producing models than are suitable for game engine use. We present an example of leveraging immersive visualization in geo-information, including the acquisition of data from the intended environment, processing it to a game engine compatible form, developing the required functions on the game engine and finally utilizing VR HMDs to deploy the application. The presented application combines 3D indoor models obtained via a commercial indoor mapping system, a 3D city model segment obtained by processing airborne laser scanning data, and a set of manually created 3D models. The performance of the application is evaluated on two different VR systems. The observed capabilities of interactive VR applications include: 1) intuitive and free exploration of 3D data, 2) ability of operate in different scales, and with different scales of data, 3) integration of different data types (such as 2D imaging and 3D models) in interactive scenes and 4) the possibility to leverage the rich interaction functions offered by the game engine platform. These capabilities could support several use cases in geo-information.
VISUALIZATION OF POINT CLOUD MODELS IN MOBILE AUGMENTED REALITY USING CONTINUOUS LEVEL OF DETAIL METHOD
Authors: Zhang L. , van Oosterom P. , Liu H.
Published: September 2020

Abstract. Point clouds have become one of the most popular sources of data in geospatial fields due to their availability and flexibility. However, because of the large amount of data and the limited resources of mobile devices, the use of point clouds in mobile Augmented Reality applications is still quite limited. Many current mobile AR applications of point clouds lack fluent interactions with users. In our paper, a cLoD (continuous level-of-detail) method is introduced to filter the number of points to be rendered considerably, together with an adaptive point size rendering strategy, thus improve the rendering performance and remove visual artifacts of mobile AR point cloud applications. Our method uses a cLoD model that has an ideal distribution over LoDs, with which can remove unnecessary points without sudden changes in density as present in the commonly used discrete level-of-detail approaches. Besides, camera position, orientation and distance from the camera to point cloud model is taken into consideration as well. With our method, good interactive visualization of point clouds can be realized in the mobile AR environment, with both nice visual quality and proper resource consumption.

Abstract. As in many countries, in The Netherlands governmental organisations are acquiring 3D city models to support their public tasks. However, this is still being done within individual organisation, resulting in differences in 3D city models within one country and sometimes covering the same area: i.e. differences in data structure, height references used, update cycle, data quality, use of the 3D data etc. In addition, often only large governmental organisations can afford investing in 3D city models (and the required knowledge) and not small organisations, like small municipalities. To address this problem, the Dutch Kadaster is collaborating with the 3D Geoinformation research group at TU Delft to generate and disseminate a 3D city model covering the whole of the Netherlands and to do this in a sustainable manner, i.e. with an implementation that ensures periodical updates and that aligns with the 3D city models of other governmental organisations, such as large cities. This article describes the workflow that has been developed and implemented.
Brief Communication: Ice Sheet Elevation Measurements from the Sentinel-3A / 3B Tandem Phase
Authors: McMillan Malcolm , Muir Alan , Donlon Craig
Published: September 2020

Abstract. Over the coming decade, the quartet of Sentinel-3 satellite altimeters will provide a continuous record of ice sheet elevation change. To ensure consistency of measurement between each of the four satellites, requires rigorous in-flight inter-comparison. To facilitate this, Sentinel-3B was initially flown in a unique tandem formation with Sentinel-3A, enabling near-instantaneous, co-located measurements to be acquired. Here, we analyse tandem measurements of ice sheet elevation, to show that both instruments operate with statistically equivalent accuracy and precision, even over complex ice margin terrain. This analysis demonstrates that both satellites can be used interchangeably to study ice sheet evolution.

Explorando el potencial del teatro en la reinserción de reclusos chilenos
Authors: Sanhueza Guillermo , Sarkis Paulina
Published: September 2020

El presente estudio se propone describir y analizar la influencia de los talleres artístico-teatrales en un grupo de personas privadas de libertad realizados en una cárcel grande masculina ubicada en Santiago de Chile. Desde la perspectiva etnográfica, el artículo recoge el significado adquirido para los internos participantes esta práctica teatral y analiza su potencial de rehabilitación, a partir de los esquemas conceptuales propuestos por Boal, Foucault y Arendt. Los internos participantes señalan que la práctica teatral fue beneficiosa para ellos por varios motivos: a) se convierte en un espacio para la recuperación de la propia dignidad y de reencuentro consigo mismos (más allá de las etiquetas carcelarias); b) pudieron desarrollar habilidades creativas y comunicativas --no violentas--entre ellos, lo cual quiebra la lógica del código carcelario; y c) percibieron que su participación les abrió caminos hacia el trabajo colaborativo, la recuperación de la confianza en el otro, y la apertura de mecanismos de reciprocidad alternativos a los ofrecidos por los patrones antisociales. Los hallazgos, en suma, sugieren que la práctica teatral es promisoria para la reinserción social.
Noesis, and Noema, and Gender—Oh My!
Authors: Rodemeyer Lanei
Published: September 2020

There is no doubt that phenomenology has something to offer to feminist philosophy and analyses of gender. We can see this already in the works of early women phenomenologists, such as Edith Stein and Simone de Beauvoir, as well as in several decades of work by more recent feminist phenomenologists. But who would have thought that Edmund Husserl's concepts of noesis and noema might contribute to contemporary work in feminist, gender, and transgender theories? While some feminist phenomenological work does turn to Husserl—rather than, say, to Maurice Merleau-Ponty or Beauvoir—most often these analyses refer to his work on embodiment (especially Ideas Pertaining to a Pure Phenomenology and to a Phenomenological Philosophy [Ideas II] [1989]), his later work on the lifeworld (The Crisis of European Sciences and Transcendental Phenomenology [1970]), or those of his unpublished manuscripts which deal with questions of intersubjectivity, ethics, and society. In this article, I argue for the usefulness of these two terms, noesis and noema, which are often considered some of Husserl's most problematic—and, if I may say so, most conservative. I begin by providing a brief overview of Husserl's introduction of these terms and what they mean. I then turn to a few later sections in Husserl's Ideas Pertaining to a Pure Phenomenology and to a Phenomenological Philosophy, First Book: General Introduction to a Pure Phenomenology [Ideas I] [1983] in order to explain the nuances of this terminology. Finally, I demonstrate how these complex notions, and the methodology that accompanies them, can be employed in the service of analyses of gender, including transgender.
Toward a “Care-ful Geopolitics” of La Frontera in the Era of Trump
Authors: Velez Emma D.
Published: September 2020

Utilizing a decolonial feminist lens, I develop an account of a “care-ful geopolitics” as alternative approach to considering La Frontera in the era of Trump. Differing from “Great Wall geopolitics,” which relies on a colonial and imperialist imaginary, a care-ful geopolitics engages in a multiscalar analysis through a decolonial imaginary, attends to complexity and contextuality, and takes seriously interdependency. Prescriptively, I argue that a care-ful geopolitics entails a global “duty to care” for and about those humans, nonhumans, and ecosystems that will be impacted by the construction of Trump's “Great Wall.”

INTRODUCTION: The purpose of the study was to assess sociodemographic determinants of patients' satisfaction with the quality of care in the General Hospitals in Ebonyi State. Four hypotheses were formulated for the study. Demographic characteristics of age, level of education, marital status, and income level on patients' satisfaction were ascertained.

METHODS: A cross-sectional survey research design was used for the study. The population of the study comprised 1, 363, 633 (18 years and above) who attended general out-patient clinics in the General Hospitals using a sample of 400. Data were analyzed using mean ( ), t-test, and analysis of variance (ANOVA) were used to answer the hypothesis at 0.05 level of significance. The SPSS version 20 was employed for the analysis.

RESULTS: Findings showed that patients who were 40–60 years ( = 2.96), had tertiary education ( = 2.97), earned income of N40, 000 – N59, 000 ( = 2.96) and were married ( = 3.09) were most satisfied. Besides, age, marital status, and income were not significantly associated (p>0.05) with patients’ satisfaction while the level of education was significant (p<0.05).

CONCLUSION: The study revealed that older age, more educated, middle-class income earners, being married were more satisfied with the quality of care received. Efforts should be made by Health workers to ensure that all patients are satisfied irrespective of their demographic characteristics.
Bevisrelaterte kompetanser i læreplanen LK20 for matematikk i grunnskolen
Authors: Valenta Anita , Enge Ole
Published: September 2020

Forskere innen matematikkdidaktikk er tydelige på at økt vektlegging av arbeid med bevis allerede i grunnskolen støtter elevers meningsskaping i matematikk og danner grunnlag for utvikling av dyp forståelse for begreper og sammenhenger. Med bevis i grunnskolen menes matematisk gyldig argumentasjon som er uttrykt på en måte som passer og er kjent for en gitt elevgruppe. I den nye læreplanen i matematikk for grunnskolen inngår bevis som en del av et kjerneelement i faget, og i denne studien ser vi nærmere på hvordan kompetanser knyttet til arbeid med bevis fremkommer på trinn 1–10. Vi har analysert læreplanen ved å bruke et rammeverk som ser på bevisrelaterte kompetanser som bestående av seks kategorier. For å tydeliggjøre relasjonene mellom de ulike kategoriene har vi sett på bevis som et element av matematisk resonnering. Analysen vår viser at læreplanen legger opp til at elever skal arbeide med flere bevisrelaterte kompetanser – de skal utforske og argumentere i matematikk og arbeide med ulike representasjoner og sammenhenger. På den annen side nevnes ikke bevis eksplisitt i den trinnspesifikke delen av læreplanen, og det er lite fokus på utvikling av logisk tankegang og arbeid med definisjoner. Det kan være til hindring for utvikling av elevers kompetanse knyttet til arbeid med bevis i grunnskolen.

Proof-related competences in the mathematics curriculum LK20 for grades 1–10

AbstractResearchers in mathematics education have long stated that a greater emphasis on proof in primary school supports students’ meaning-making in mathematics and creates foundations for deep understanding of concepts and connections. We take proof in primary and lower secondary school to mean mathematical valid argumentation using forms of expressions that are appropriate and known to a given group of students. The new Norwegian curriculum for school mathematics includes proof as a part of one of its core elements, and in this study we explore how competences connected to work with proof are spelled out for grades 1–10. We have analyzed the curriculum using a framework which conceptualizes proof-related competences into six categories. In order to uncover relationships between the categories, we see proof as a part of mathematical reasoning. Our analysis shows that the curriculum addresses several of the proof-related categories – students shall work with investigations, representations, relationships and argumentation. However, the notion of proof is not mentioned as a part of the goals for each grade, and there is very little focus on development of logical thinking and work with definitions. This can hinder the development of students’ competence with proof and proof related work in primary and lower secondary school.

The high-performance HRM systems in shaping employee performance – an analysis into the mediating effect of the psychological contract based on organisations in Central Poland
Authors: Rogozińska-Pawełczyk Anna
Published: September 2020

This paper uses independent and intermediate variables (individual and organisational) to study employee performance. It was prepared based on a literature review and a study of relations between the high-performance systems (the main predictor) and employee performance (composed of their behaviours and performance) mediated by the fulfilment of psychological contract. The research showed that the high-performance HRM systems (consisting of content, process and climate) directly and indirectly influence employee performance through the mediating effect of the psychological contract setting out the obligations of employers and employees towards each other.
Die normative Grundlage intergenerationeller Unternehmensethik Zwei Ansätze, zwei Schwierigkeiten
Authors: Seidel Christian
Published: September 2020

Man kann zwei Auffassungen über die normative Grundlage einer intergenerationellen unternehmensethischen Theorie (IUET) unterscheiden, akteursvariante und akteursinvariante IUET. Jede von ihnen ist mit jeweils einer spezifischen Schwierigkeit konfrontiert: Akteursvariante IUET sind dem inversen Nichtidentitätsproblem (INIP) ausgesetzt, akteursinvariante IUET dem Problem des moralischen Verdrängungseffekts (MVEP). Diese Schwierigkeiten sind besonders hartnäckig, wenn man in einem nicht-reduktionistischen Rahmen bleibt und Unternehmen als eigenständige moralische Akteure versteht, deren Verantwortung sich nicht auf die Verantwortung individueller Akteure oder übergeordneter Institutionen zurückführen lässt. Das könnte dafürsprechen, in intergenerationellen Kontexten eher einen reduktionistischen Ansatz zu verfolgen.
A Proposal for a Coherentist-Constitutivist Account of Normativity
Authors: Cheng Yixue (Anna) ,   Ball State University
Published: September 2020

We operate under norms of evaluating actions as good and bad, right and wrong, or reasonable and unreasonable. What justifies the authority of these norms? Christine Korsgaard takes the constitutivist position and argues that self-constitution, as the standard for what constitutes action, is the source of normativity. David Enoch argues that it is impossible for any constitutivist model to justify normative standards, and that realism is the best solution. In this paper, I demonstrate that the best solution to the tensions Enoch raises is not realism, but an original coherentist-constitutivist model of normativity rooted in Korsgaardian constitutivism.
A Step Toward the Elucidation of Quantitative Laws of Nature
Authors: Perry Stephen ,   Ball State University
Published: September 2020

When we mathematically model natural phenomena, there is an assumption concerning how the mathematics relates to the actual phenomenon in question. This assumption is that mathematics represents the world by “mapping on” to it. I argue that this assumption of mapping, or correspondence between mathematics and natural phenomena, breaks down when we ignore the fine grain of our physical concepts. I show that this is a source of trouble for the mapping account of applied mathematics, using the case of Prandtl’s Boundary Layer solution to the Navier-Stokes equations.

Two new species of Kaempferia L. (Zingiberaceae), Kaempferia nemoralis Insis. sp. nov. and Kaempferia pascuorum Insis. sp. nov., from Cambodia and Lao PDR are described and illustrated. Morphological similarities to their closely related taxa are discussed. Kaempferia nemoralis Insis. sp. nov. is compared with Kaempferia larsenii Sirirugsa in its vegetative parts, but distinguished by the following characters: whole plant taller, leaf sheath and young shoot apex green, petiole absent. It differs from Kaempferia rotunda L. in its floral parts by the following characters: presence of peduncle, floral tube longer, labellum purple with white line at centre, anther crest obovate, bifid, apex irregularly rounded and ovary glabrous. Kaempferia pascuorum Insis. sp. nov. is compared with Kaempferia larsenii Sirirugsa. Proposed IUCN conservation assessments are also given: Kaempferia nemoralis Insis. sp. nov. occurs in disturbed, open forest and is assessed as CR, whereas Kaempferia pascuorum Insis. sp. nov. occurs in short grassland and is assessed as EN.
Multiorgan Immune-Related Adverse Events During Treatment With Atezolizumab
Authors: Kichenadasse Ganessan , Miners John O. , Mangoni Arduino A. , Rowland Andrew , Hopkins Ashley M. , Sorich Michael J.
Published: September 2020

Background: Immune-related adverse events (irAEs) are known to occur in patients with cancer who are treated with immune checkpoint inhibitors. However, limited literature exists on the incidence, time of onset, and risk factors for irAEs, particularly those affecting multiple organs, associated with anti–PD-L1 inhibitors. Methods: A post hoc pooled analysis was conducted using individual patient data from atezolizumab monotherapy arms of 4 non–small cell lung cancer clinical trials. Incidence, clinical patterns, outcomes, and risk factors were investigated of selected organ-specific and multiorgan irAEs during treatment using the anti–PD-L1 inhibitor atezolizumab. Results: From a total of 1,548 patients, 730 irAE episodes were reported in 424 patients (27%). Skin irAEs were the most common (42%), followed by laboratory abnormalities (27%) and endocrine (11.6%), neurologic (7.6%), and pulmonary (6.2%) irAEs. A total of 84 patients (5.4%) had multiorgan irAEs, 70 had 2, 13 had 3, and 1 had 4 different organs affected. “Skin plus” or “laboratory plus” were the most common irAE multiorgan clusters. Patients with multiorgan irAEs were more likely to be white and have a good performance status, a lower baseline neutrophil-lymphocyte ratio, and a good or intermediate lung immune prognostic index score. Multiorgan irAEs were also associated with improved overall survival (hazard ratio, 0.47; 95% CI, 0.28–0.78; P<.0001) but not with progression-free survival (hazard ratio, 0.92; 95% CI, 0.62–1.35; P=.74) compared with the cohort with no irAEs. Conclusions: Multiorgan irAEs occurred in 5.4% of patients treated with atezolizumab in non–small cell lung cancer trials. Future trials should consider routine reporting of data on multiorgan toxicities in addition to organ-specific toxicities.
Exact Green's formula for the fractional Laplacian and perturbations
Authors: Grubb Gerd
Published: September 2020

Let Ω be an open, smooth, bounded subset of $ \mathbb{R}^n $. In connection with the fractional Laplacian $(-\Delta )^a$ ($a>0$), and more generally for a $2a$-order classical pseudodifferential operator (ψdo) $P$ with even symbol, one can define the Dirichlet value $\gamma _0^{a-1}u$, resp. Neumann value $\gamma _1^{a-1}u$ of $u(x)$, as the trace, resp. normal derivative, of $u/d^{a-1}$ on $\partial \Omega $, where $d(x)$ is the distance from $x\in \Omega $ to $\partial \Omega $; they define well-posed boundary value problems for $P$.

A Green's formula was shown in a preceding paper, containing a generally nonlocal term $(B\gamma _0^{a-1}u,\gamma _0^{a-1}v)_{\partial \Omega }$, where $B$ is a first-order ψdo on $\partial \Omega $. Presently, we determine $B$ from $L$ in the case $P=L^a$, where $L$ is a strongly elliptic second-order differential operator. A particular result is that $B=0$ when $L=-\Delta $, and that $B$ is multiplication by a function (is local) when $L$ equals $-\Delta $ plus a first-order term. In cases of more general $L$, $B$ can be nonlocal.
Jaka jest reprezentacja formalna wsi w Polsce? Studium wojewódzkich programów odnowy wsi = What is the formal representation of the rural in Poland? The case of rural renewal programmes
Authors: Wolski Oskar
Published: September 2020

The paper presents results of the research concerning formal representations of the rural in Poland. K. Halfacree’s (2006) research model of rural space was applied. Theoretical framework of the study also comprises debate on defining the rural under post-structuralism and some considerations of rural renewal. The research employed content analysis of rural renewal programmes in Poland. The outcomes were interpreted and discussed in relation to a broader process of socio-economic and cultural transformation and the notion of change in the rural space. It was explained how the formal representation of the rural is created in the rural renewal programmes. The formal representation of the rural in rural renewal programmes does not vary in regional terms, often being chaotic and incoherent. The rural is perceived through rural community and rural space separately, and as a broader concept opposite to the urban. Representation refers to, first and foremost, rural identity. However, it does not specify what defines such identity. It merely reproduces certain tags and slogans about the rural, and thus it is based on the rural myth. It also dissociates itself from agriculture as an economic function, but not as a culture-forming one.
«We are Here». Economía cultural indie y autenticidad aurática audiovisual
Authors: Arnold Michael
Published: September 2020

Este artículo investiga la economía cultural de la escena indie internacional con un enfoque especial en la banda de neoflamenco indie con base en Sevilla llamada Pony Bravo y, específicamente, en Daniel Alonso Mallén, cantante de la banda y visionario prolífico del montaje gráfico y sonoro. Pony Bravo se basa en una variedad de tradiciones musicales, conectando el sonido y el ritmo de los distintos «sures» marginados: El blues y el rock de sureño de Estados Unidos, el rock andaluz, el flamenco, los ritmos africano y jamaicano, etc. Mientras juegan con estas tradiciones, el grupo utiliza su plataforma para luchar por el derecho a hacerlo: tomar prestado, samplear, citar, remezclar, collagear, reciclar los ritmos, melodías, armonías, letras, ideas e imágenes de los creadores y embaucadores que los precedieron. Con la ayuda de la dicotomía de Walter Benjamin entre formas de arte auráticas y no auráticas, este artículo explora la inflación del capital subcultural en la música indie (a través de la asimilación de los conocimientos no auráticos) y la elevación del artefacto aurático (el concierto en vivo) como una reacción de quienes querrían controlar esa inflación. Daniel Alonso eleva el momento aurático capturado como contenido dentro de la forma no aurático del cartel promocional archivado en línea. Simultáneamente, aboga por la aniquilación de todas las formas de lo no aurático en su abrazo de una especie de socialismo con respecto al capital cultural a través de las licencias Creative Commons en vez de la propiedad intelectual y su postura antagónica hacia las instituciones (SGAE) y la legislación (la ley Sinde) que luchan por la protección de los derechos de propiedad intelectual de artistas nacionales e internacionales.

Analizamos en este artículo la presencia, en el corto de animación Destino (2003), de algunos de los motivos plásticos más recurrentes en la obra de Salvador Dalí. Por él irán desfilando los relojes blandos, las muletas, la sensación de hormigueo y hasta la más fatídica o la más deseada de las horas. Procedemos a hacer un recuento de dichos motivos, aquí animados, y a darle un sentido a su presencia tanto en el corto como, por extensión, en la obra del pintor de Figueras.
Modernizando la nación: Democracia y autoritarismo en el comité fílmico de la industria petrolera (Venezuela, 1947-1951)
Authors: Colmenares España María Gabriela
Published: September 2020

Tras la reforma petrolera de 1943, las compañías petroleras transnacionales con intereses en Venezuela se alinearon con el nacionalismo moderado de las nuevas élites gobernantes y se presentaron como indispensables para el progreso de la nación. Para esto, establecieron departamentos de relaciones públicas, programas de responsabilidad social y de mecenazgo cultural (Tinker Salas, 2009). En este contexto, también crearon programas fílmicos destinados a su fuerza laboral y al público venezolano. El primero de estos programas fue el Comité Fílmico de la Industria Petrolera (1947-1951). Enfocando este programa fílmico desde la categoría cine empresarial, propuesta por Hediger y Vonderau (2009a), analizaré Venezuela elige su destino (Gunther von Fritsch, 1948) y Vialidad, símbolo de progreso (Arteries of Progress, Henwar Rodakiewicz, 1950). Mi análisis tomará en cuenta sus circunstancias de producción y recepción, y se centrará en la manera en que los filmes representaron la modernización nacional, tal como la entendieron los gobiernos del llamado Trienio Adeco (1945-1948) y la Década Militar (1948-1958). Todo esto para concluir que las películas empresariales del Comité Fílmico de la Industria Petrolera evidenciaron, en primer lugar, la competencia entre el Estado y las transnacionales petroleras por posicionarse como agentes modernizadores y, en segundo lugar, el sometimiento de las compañías a la soberanía del Estado a través de su conformidad con las políticas de los regímenes que, en forma sucesiva, gobernaron el país entre 1947 y 1951.

Identidad cultural latinoamericana: la mirada heteróclita y la reivindicación del indígena
Authors: Moreno Xiomara Leticia
Published: September 2020

Se presentan dos perspectivas que buscan definir la concepción de una identidad cultural latinoamericana. La sustentada en el colonialismo heteróclito y, la más actual, de las reivindicaciones indígenas. Ambas han sido preocupaciones recorridas desde el siglo XIX como posibles salidas para un reconocimiento de un ser cultural identificable por cada uno de los fragmentos que conforman los Estados nacionales en América Latina. La reflexión se sustenta en autores como Mariano Picón Salas, José Carlos Mariátegui, Octavio Paz, Roberto Fernández Retamar, Augusto Roa Bastos, Arturo Uslar Pietri, John Beverley, y Ronny Velasquez, entre otros estudiosos de la cultura.

Published: September 2020

Platelet-rich plasma (PRP) has been reported recently as a potential therapeutic approach for alopecia, such as androgenetic alopecia, but the exact mechanisms and effects of specific components of this recipe remain largely unknown. In this study, we identified that platelet factor 4 (PF4), a component of PRP, significantly suppressed human hair follicle growth and restrained the proliferation of human dermal papilla cells (hDPCs). Furthermore, our results showed that PF4 upregulated androgen receptor (AR) in human dermal papilla cells in vitro and via hair follicle organ culture. Among the hair growth-promoting and DP-signature genes investigated, PF4 decreased the expression of Wnt5a, Wnt10b, LEF1, HEY1 and IGF-1, and increased DKK1 expression, but did not affect BMP2 and BMP4 expression. Collectively, Our data demonstrate that PF4 suppresses human hair follicle growth possibly via upregulating androgen receptor signaling and modulating hair growth-associated genes, which provides thought-provoking insights into the application and optimization of PRP in treating hair loss.

This study was carried out to evaluate the nutritional content of ‘Aju Mbaise’ herbal mixture. The experiment involves the collection of fresh plant samples that make up ‘Aju Mbaise’ cocktail. The study was done in the Research Laboratory of the Department of Biochemistry, Faculty of Science, University of Port Harcourt, Nigeria. The plants samples were collected from Mbaise locality in Imo State, Nigeria, and were identified as Cnestis ferruginea, Xylopia aethiopica, Uvaria chamae, Palisota hirsuta, Scleria sp., Napoleona imperialis, Dialium guineense, Combretum racemosun, and Heterotis rotundifolia respectively. The dietary, mineral, and vitamin compositions were determined accordingly. The proximate, vitamin, and mineral composition of the herbal cocktail were investigated in line with their standard methods of analysis. The proximate analysis revealed that the cocktail extract contains carbohydrate (69.51%), crude protein (10.05%), moisture (8.89%), crude fat (5.17%), fibre (3.745), and ash content (2.65%). The vitamin analysis revealed reasonable concentration of vitamins A, B1, B2, B3, B6, B12, C, D, and K. The mineral evaluation showed high concentration of calcium, magnesium, potassium, sodium, zinc, and iron. This study revealed high nutritional value of ‘Aju Mbaise’ herbal cocktail which is responsible for the plant’s usefulness in the management, treatment, as well as maintenance of good health.

Published: September 2020

Background: Since the confirmation of the index case of Covid-19 on the 27th of February in Nigeria, the spread from Lagos to other parts of the country has been on the climb without a plateau in sight.

Objective: To characterize and present epidemiological trends of Covid-19 pandemic in the first three months of index confirmation in Nigeria.

Methods: A descriptive epidemiological study involving a review of the first three-month Covid-19 situation reports and updates in Nigeria using primary data was analyzed by Spatio-temporal analysis with categorical variables reported in percentages and numbers.

Findings: Retrospective analysis revealed 8344 confirmed cases in 35 of the 36 states (with the federal capital territory inclusive), 249 fatalities, 2385 discharged cases, 48544 laboratory testing, 5710 total active cases, a mortality rate of 0.12 per 100,000 population, and a Case Fatality Rate (CFR) of 3. It further showed an increased number of confirmed cases in densely populated states. Transmission via contact with infected persons accounted for 23% of a confirmed case. Additionally, 17% (circa) of the tested population were confirmed positive.

Conclusion: Causation and spread are attributed to travel and contact risk factors. Early epidemiological patterning occurred along population density and outdoor exposure lines. Aggressive and continuous testing would reveal more cases especially asymptomatic cohorts in the population.

Introduction: Created from Brazilian social and sanitary movements, the Unified Health System (SUS) has changed the concept of health, its management, and how society should actively participate in this process. Portrait n. 154, dated January 24, 2008, created the Family Health Support Centers (NASF), and with it emerged the need to organize the professional practices of Physical Therapy in all actions of its responsibility, through the Health Strategy of the family. Physical Therapy in Basic Health Care is a process under construction that faces challenges since the physiotherapist is trained for rehabilitation.

Objective: To demonstrate significantly the importance of the physiotherapist in the Family Health Support Center.

Materials and Methods: This is a qualitative bibliographic review with an exploratory design, carried out through a bibliographical survey related to the theme The Importance of Physical Therapist Performance in the Family Health Support Center, published since 2006, in the Portuguese language. The descriptors were: Physiotherapist; Family Health; Primary Health Care; Public health for search. The exclusion attributes were: publications inferior to the year 2006 and that flee from the selected theme. The surveys will be carried out in the following databases, Medline, VBS, Lilacs, Scielo, Google Scholar, and Official Sites of the Government of Brazil.

Conclusion: The physiotherapist when inserted within the NASF (Family Health Support Nucleus) team is a fundamental piece, fulfilling its role in primary care investing in the promotion and prevention of diseases and their diseases, recovery, rehabilitation and quality improvement of life of the population, with an integral practice that per passes by the education in health, reception, individual attendance. The literary shortage when the subject is Basic Attention mainly in what concerns the NASF, making difficult the understanding of the importance and the role of preventive Physiotherapy in this context. For physiotherapy to be increasingly recognized, the training of professionals capable of acting in this area should be encouraged.
Evaluating the Challenges in Pressure – Volume – Temperature (PVT) Analysis of Gas Condensate Reservoirs
Authors: Usungedo Aniedi B. , Akpabio Julius U.
Published: September 2020

Aims: The variations in production performances of the Black oil and compositional simulation models can be evaluated by simulating oil formation volume factor (Bo), gas formation volume factor (Bg), gas-oil ratio (Rs) and volatilized oil-gas ratio (Rv). The accuracy of these two models could be assessed.

Methodology: To achieve this objective some basic parameters were keyed into matrix laboratory (MATLAB) using the symbolic mathematical toolbox to obtain accurate Pressure Volume Temperature (PVT) properties which were used in a production and systems analysis software to generate the production performance and hydrocarbon recovery estimation. Standard black oil PVT properties for a gas condensate reservoir was simulated by performing a series of ﬂash calculations based on compositional modeling of the gas condensate ﬂuid at the prescribed conditions through a constant volume depletion (CVD) path. These series of calculations will be carried out using the symbolic math toolbox. PVT property values obtained from both compositional modeling and black oil PVT prediction algorithm are incorporated to determine the production performance of each method for comparison.

Results: The absolute open flow for the black oil PVT algorithm and the compositional model for the Rs value of 500 SCF/STB and Rs value of 720SCF/STB were 130,461 stb/d and 146,028 stb/d respectively showing a 10.66% incremental flow rate.

Conclusion: In analyzing PVT properties for complex systems such as gas condensate reservoirs, the use of compositional modeling should be practiced. This will ensure accurate prediction of the reservoir fluid properties.
