CONTOUR EXTRACTION OF PLANAR ELEMENTS OF BUILDING FACADES FROM POINT CLOUDS USING GLOBAL GRAPH-BASED CLUSTERING
Authors: Xu Y. , Stilla U.
Published: September 2019

Abstract. In this work, we present a surface-based method to extract the contours of planar building elements in the urban scene. A bottom-up segmentation method that utilizes global graph-based optimization and supervoxel structure is developed, enabling an automatic and unsupervised segmentation of point clouds. Then, a planarity-based extraction is conducted to segments, and only the planar segments, as well as their neighborhoods, are selected as candidates for the plane fitting. The points of the plane can be identified by the parametric model given by the planarity calculation. Afterward, the boundary points of the extracted plane are extracted by the alpha-shape. Optionally, line segments can be fitted and optimized by the energy minimization with the local graphical model. The experimental results using different datasets reveal that our proposed segmentation methods can be effective and comparable with other method, and the contours of planar building elements can be well extracted from the complex urban scene.

Abstract. High-precision on-orbit geometric calibration of spaceborne laser altimetry data is essential to its effective applications. Firstly, the existing calibration methods for laser altimeter data are analyzed. Then, a geometric calibration method based on curve matching is proposed. Compared to the existing methods, the proposed method does not rely on ground calibration field. Thus, it is efficiency in expense and time. Notably, three factors, i.e. matching method, initial control point selection and the step size of matching step, which significantly affect the results of calibration are analyzed respectively. The analysis was validated based on the original laser altimetry data obtained by ZY3-02 satellite. According to the results, the following conclusions can be drawn preliminarily: (1) Both the correlation coefficient maximum (COR) criterion and the mean square error minimum (MSD) criterion in the curve matching can be used to correct the systematic error in altimetry data. (2) The initial control points of the selected track should have a significant change trend and the slope within the laser footprints should be less than 15°. (3) Current experimental data show that the best step size for matching search is 10 m. The relevant conclusions can provide reference for the research of geometrical calibration and data processing of the same type of laser altimetry satellite.

Abstract. This work follows a line of research dedicated to the parallelization of image segmentation algorithms on distributed computing environments, which is motivated by the increasing resolutions and availability of Remote Sensing (RS) images. Here we focus on region-growing segmentation, which is regarded as a time consuming and demanding approach in terms of computational resources. Its parallelization is a complex problem since it usually affects the final outcome in comparison to what would be delivered by a sequential solution. This is due to the fact that subdividing an image to perform segmentation of its tiles concurrently usually introduces undesirable artifacts near to the borders of the image tiles. Additional processing steps are then required to properly stitch together the segments alongside tiles borders in order to eliminate such artifacts. In this work we evaluated alternative implementations of a previously proposed region-growing distributed segmentation approach, which was originally built on top of the Hadoop distributed computing framework. We developed a new implementation of the approach, which was built with the Spark framework, and compared its performance with that of the original implementation. In this investigation RS images of various sizes were processed using different configurations of a physical computer cluster. We evaluated computational performances and accessed the differences among the segmentation outcomes generated by the alternative implementations. We also assessed the stability of the implementations by comparing the segmentations produced with different cluster configurations. Although the approach is, in principle, suitable to any region growing algorithm, the experiments were performed with a particular segmentation method, and the results showed that the Spark implementation consistently outperformed the Hadoop counterpart, bringing in most cases a significant improvement in terms of processing time. The experiment results also attested the stability of the distributed segmentation approach, as very similar results were produced with the alternative implementations, running on different cluster configurations.
DEVELOPMENT OF A HIGH-SPEED VIDEOGRAMMETRIC MEASUREMENT SYSTEM WITH APPLICATION IN LARGE-SCALE SHAKING TABLE TEST

Published: September 2019

Abstract. The high-speed videogrammetric measurement system, which provides a convenient way to capture three-dimensional (3D) dynamic response of moving objects, has been widely used in various applications due to its remarkable advantages including non-contact, flexibility and high precision. This paper presents a distributed high-speed videogrammetric measurement system suitable for monitoring of large-scale structures. The overall framework consists of hardware and software two parts, namely observation network construction and data processing. The core component of the observation network is high-speed cameras to provide multiview image sequences. The data processing part automatically obtains the 3D structural deformations of the key points from the captured image sequences. A distributed parallel processing framework is adopted to speed up the image sequence processing. An empirical experiment was conducted to measure the dynamics of a double-tube five-layer building structure on the shaking table using the presented videogrammetric measurement system. Compared with the high-accuracy total station measurement, the presented system can achieve a sub-millimeter level of coordinates discrepancy. The 3D deformation results demonstrate the potential of the non-contact high-speed videogrammetric measurement system in dynamic monitoring of large-scale shake table tests.
A REPRESENTATION OF MLS DATA AS A BASIS FOR TERRAIN NAVIGABILITY ANALYSIS AND SENSOR DEPLOYMENT PLANNING
Authors: Gehrung J. , Hebel M. , Arens M. , Stilla U.
Published: September 2019

Abstract. Recording an ever-changing urban environment in a structured manner requires sensor deployment planning. In case of mobile sensor platforms, this also includes verifying the terrain navigability. Solving both tasks would usually require different application-specific data structures and tools. In this work, we propose a theoretical framework that provides a uniform representation for spatial information as well as the tools required to combine, manipulate and visualize it. We provide an efficient implementation of the framework utilizing octree-based evidence grids. Our approach can be used to solve complex tasks by combining simple spatial information sources, which we demonstrate by providing simple solutions to the aforementioned applications. Despite the use of a volumetric approach, our runtimes are within the range of minutes.
MONOCULAR-DEPTH ASSISTED SEMI-GLOBAL MATCHING

Published: September 2019

Abstract. Reconstruction of dense photogrammetric point clouds is often based on depth estimation of rectified image pairs by means of pixel-wise matching. The main drawback lies in the high computational complexity compared to that of the relatively straightforward task of laser triangulation. Dense image matching needs oriented and rectified images and looks for point correspondences between them. The search for these correspondences is based on two assumptions: pixels and their local neighborhood show a similar radiometry and image scenes are mostly homogeneous, meaning that neighboring points in one image are most likely also neighbors in the second. These rules are violated, however, at depth changes in the scene. Optimization strategies tend to find the best depth estimation based on the resulting disparities in the two images. One new field in neural networks is the estimation of a depth image from a single input image through learning geometric relations in images. These networks are able to find homogeneous areas as well as depth changes, but result in a much lower geometric accuracy of the estimated depth compared to dense matching strategies. In this paper, a method is proposed extending the Semi-Global-Matching algorithm by utilizing a-priori knowledge from a monocular depth estimating neural network to improve the point correspondence search by predicting the disparity range from the single-image depth estimation (SIDE). The method also saves resources through path optimization and parallelization. The algorithm is benchmarked on Middlebury data and results are presented both quantitatively and qualitatively.
SEMANTIC LABELING AND REFINEMENT OF LIDAR POINT CLOUDS USING DEEP NEURAL NETWORK IN URBAN AREAS
Authors: Huang R. , Ye Z. , Hong D. , Xu Y. , Stilla U.
Published: September 2019

Abstract. In this paper, we propose a framework for obtaining semantic labels of LiDAR point clouds and refining the classification results by combining a deep neural network with a graph-structured smoothing technique. In general, the goal of the semantic scene analysis is to assign a semantic label to each point in the point cloud. Although various related researches have been reported, due to the complexity of urban areas, the semantic labeling of point clouds in urban areas is still a challenging task. In this paper, we address the issues of how to effectively extract features from each point and its local surrounding and how to refine the initial soft labels by considering contextual information in the spatial domain. Specifically, we improve the effectiveness of classification of point cloud in two aspects. Firstly, instead of utilizing handcrafted features as input for classification and refinement, the local context of a point is embedded into deep dimensional space and classified via a deep neural network (PointNet++), and simultaneously soft labels are obtained as initial results for next refinement. Secondly, the initial label probability set is improved by taking the context both in the spatial domain into consideration by constructing a graph structure, and the final labels are optimized by a graph cuts algorithm. To evaluate the performance of our proposed framework, experiments are conducted on a mobile laser scanning (MLS) point cloud dataset. We demonstrate that our approach can achieve higher accuracy in comparison to several commonly-used state-of-the-art baselines. The overall accuracy of our proposed method on TUM dataset can reach 85.38% for labeling eight semantic classes.
SEMANTIC CHANGE DETECTION OF RIVER GROUND POINTS IN AIRBORNE LIDAR BATHYMETRY DATA USING VOXEL OCCUPANCIES
Authors: Boerner R. , Hoegner L. , Stilla U.
Published: September 2019

Abstract. This paper proposes a method to get semantic information of changes in bathymetric point clouds. This method aims for assigning labels to river ground points which determine if either the point can be compared with a reference DEM, if there are no data in the reference or if there are no water points inside the new Data of wet areas of the reference data. This labels can be further used to specify areas where differences of DEMS can be calculated, the comparable areas. The Areas where no reference data is found specify areas where the reference DEM will have a higher variance due to interpolation which should be considered in the comparison. The areas where no water in the new data was found specify areas there no refraction correction in the new data can be done and which should be considered with a higher variance of the ground points or there the water surface should be tried to reconstruct. The proposed approach uses semantic reference data to specify water areas in the new scan. An occupancy analysis is used to specify if voxels of the new data exist in the reference or not. In case of occupancy, the labels of the reference are assigned to the new data and in case of no occupancy, the label of changed data is assigned. A histogram based method is used to separate ground and water points in wet areas and a second occupancy analysis is used to specify the semantic changes in wet areas. The proposed method is evaluated on a proposed data set of the Mangfall area where the ground truth is manually labelled.
RULE-BASED MAPPING OF PARKED VEHICLES USING AERIAL IMAGE SEQUENCES

Published: September 2019

Abstract. Mapping of parking spaces in cities is a prerequisite for future applications in parking space management like community-based parking. Although terrestrial or vehicle based sensors will be the favorite data source for parking space mapping, airborne monitoring can play a role in building up city wide basis maps which include also parking spaces on ancillary and suburban roads. We present a novel framework for automatic city wide classification of vehicles in moving, stopped and parked using aerial image sequences and information from a road database. The time span of observation of a specific vehicle during an image sequence is usually not long enough to decide unambiguously, whether a vehicle stopped e.g. before a traffic light or is parking along the road. Thus, the workflow includes a vehicle detection and tracking method as well as a rule-based fuzzy-logic workflow for the classification of vehicles. The workflow classifies stopped and parked vehicles by including the neighbourhood of each vehicle via a Delaunay-Graph. The presented method reaches correctness values of around 86.3%, which is demonstrated using three different aerial image sequences. The results depend on several factors like detection quality and road database accuracy.
La durée dans la dureté: Espaces de la mémoire et mémoires de l’espace chez Paul Ricœur
Authors: D'Alessandris Francesca
Published: September 2019

Dans La mémoire, l’histoire, l’oubli, Ricœur ne parvient pas à donner une définition claire de la mémoire collective. Dans cet article, nous cherchons à montrer comment elle se laisse néanmoins décrire, à partir de ce même texte, comme la capacité à reconnaître, à travers l’attribution réciproque, des souvenirs qui s’inscrivent dans les espaces temporels partagés avec nos proches et, à travers ces derniers, avec les étrangers. Afin d’appuyer cette hypothèse, nous analysons les réflexions de Ricœur sur l’architecture en tant qu’inscription de la mémoire publique dans l’espace, présentées pour la première fois dans le texte “Architecture et narrativité.” Deuxièmement, nous considérons l’imagination et la mémoire corporelle, à savoir l’habitude qui découle de l’acte d’habiter, comme les conditions de possibilité de la cristallisation des souvenirs dans les lieux partagés.
Ricoeur et la mémoire des proches: “Moi, les collectifs, les proches”
Authors: Mouratian Anaïd
Published: September 2019

“Moi, les collectifs, les proches”: Ricœur désigne par-là les sujets d’attribution du souvenir pour clore le parcours de la première partie de son œuvre, La mémoire, l’histoire, l’oubli, publiée en 2000. Ricœur, lecteur des sciences sociales, évoque dans ce chapitre le travail d’Alfred Schütz et la sociologie phénoménologique. L’exploration d’un plan intermédiaire de la mémoire (entre la mémoire personnelle et la mémoire collective) dans la relation aux proches sera l’occasion d’un détour herméneutique vers ce lien social de la proximité. “Sur quel trajet d’attribution de la mémoire se situent les proches?” se demande Ricœur. C’est dans un dialogue instructif avec Schütz que nous tenterons de poser des jalons. En effet, les proches sont l’occasion de penser la reconnaissance par le chemin du souvenir. Dans cette exploration de l’attribution des souvenirs s’ouvre la connexion de la mémoire à la reconnaissance à une échelle particulière du lien social, celle de la proximité.
Paul Ricœur et Emmanuel Levinas: vulnérabilité, mémoire et narration: Peut-on raconter la vulnérabilité?
Authors: Galabru Sophie
Published: September 2019

Dans Temps et récit puis dans Soi-même comme un autre, Paul Ricœur propose une philosophie de l’identité personnelle et collective, à travers des recherches menées sur le temps et la narration. Le récit, selon ces ouvrages, permettrait de synthétiser et de réconcilier la discordance temporelle subie par un sujet. L’éclatement du sujet par l’altérité du temps pourrait alors définir sa vulnérabilité. Nous voudrions revenir sur cette triade temps-vulnérabilité-narration en la confrontant à la philosophie d’Emmanuel Levinas. Contrairement à Ricœur, Levinas critique sévèrement l’idée de la mémoire et du récit afin de respecter la vulnérabilité d’autrui. Pourtant, l’analyse ricœurienne de la responsabilité affirme la nécessité d’un Soi capable et non point dépossédé. De ce point de vue, Ricœur nous aide à questionner les limites posées par Levinas à la narration et nous pousse à nous demander si l’intrigue éthique pour la vulnérabilité d’autrui n’a pas besoin de la mémoire et du récit.
Paul Ricœur: Raconter, se souvenir et oublier
Authors: Waldenfels Bernhard
Published: September 2019

Ce texte de Bernhard Waldenfels est issu de la seconde partie de son livre Socialité et altérité – modes de l’expérience sociale (Sozialität und Alterität – Modi sozialer Erfahrung (Berlin, Suhrkamp, 2015), 363-85), où l’auteur met à l’épreuve et approfondit sa théorie de la responsivité à travers une série de débats avec Husserl, Schütz et Gurwitsch, Searle, Castoriadis, Foucault et Ricœur. Dans sa discussion avec ce dernier, il insiste sur les thèmes du souvenir et de l’oubli, en prenant pour base Temps et récit et La mémoire, l’histoire, l’oubli. Le texte se compose de quatre sections. Dans les deux premières, Waldenfels retrace les arguments de Ricœur en insistant notamment sur le manque d’importance accordé à l’oubli dans le récit par Ricœur. Dans les deux dernières, l’auteur propose une révision de la philosophie ricoeurienne de l’oubli sous le signe d’une phénoménologie responsive. À la fois à partir de Ricœur et aussi contre lui, Waldenfels considère l’oubli comme un pathos face auquel nous n’avons pas d’autre choix que répondre.
The Time of Collective Memory: Social Cohesion and Historical Discontinuity in Paul Ricœur’s Memory, History, Forgetting
Authors: Barash Jeffrey Andrew
Published: September 2019

One of principal tasks of Paul Ricoeur’s Memory, History, Forgetting is to analyze the phenomenon of social cohesion, understood not as a uniform bond, but in terms of human plurality that arises from a diversity of perspectives of remembering groups rooted in complex stratifications and concatenations. This paper focuses on the role of remembrance and of its historical inscription as a source of social cohesion, which is subject to rupture and dissolution over time. It first identifies the way in which, according to Ricœur, memory and history function as essential preconditions of social cohesion; following this, it examines the significance and scope of temporal rupture and discontinuity to which this cohesion is subject. In examining Ricœur’s reflection on social cohesion and on the discontinuity to which it is subject over time, I aim to place his thought in a critical light in order to set in relief what I take to be an important aporia it encounters.

Gallbladder Agenesis in a Dog: Clinicopathological, Histopathology, and Computed Tomography Findings
Authors: Kelly Darren , Moreno-Aguado Beatriz , Lamb Valerie
Published: September 2019

Three cases of gallbladder agenesis (GA) have been previously reported in the English-speaking veterinary literature. Affected dogs can be either asymptomatic or symptomatic with vomiting, retching, and anorexia previously reported. The previously reported cases and the dog in this report had marked elevations in alanine aminotransferase concentrations, and liver histopathology consistently showed bridging fibrosis and biliary hyperplasia. The condition is most often diagnosed in humans during exploratory surgery, which was also the case in the previous three dogs reported with GA. Computed tomography (CT) or MRI is now recommended for diagnosis of the condition in humans, and this is the first report of CT findings in an affected dog diagnosed without surgery. Bile stasis and cholangiohepatits have been proposed as secondary pathologies in both humans and dogs with GA, and histopathology and CT findings in this case support those theories.

Published: September 2019

Tail docking is a routine procedure for rottweilers in the United States and Canada. A cross-sectional comparative study was conducted in tailed (n = 25) and docked (n = 39) rottweilers ≥5 yr old to compare prevalence and severity of spondylosis deformans in the lumbar spine between groups. The prevalence of spondylosis was 68.0% in tailed dogs and 76.9% in docked dogs, which was not significantly different (P = .563). Distribution of spondylosis severity did not significantly differ between tailed and docked dogs (P = .102). Logistic regression found moderate to severe spondylosis was associated with age and sex. Females were three times at greater risk than males (odds ratio 3.10, 95% confidence interval 1.060–9.08; P = .039). Risk increased 1.4 times for each additional year (odds ratio 1.43, 95% confidence interval 1.02–1.99, P = .036). Tail docking may not impact or only play a minor role in spondylosis deformans in rottweilers.
O Customer-Based Brand Equity do Complexo Turístico Itaipu: uma comparação entre as percepções dos visitantes do lado brasileiro e paraguaio
Authors: Chibiaqui Rodrigo , Neto Eduardo Hack
Published: September 2019

Atrativos turísticos são normalmente analisados sob o enfoque da imagem, desconsiderando outras dimensões que compõem o Customer-Based Brand Equity (CBBE). O atrativo objeto desta pesquisa é a usina Itaipu Binacional, que possui complexos turísticos em suas duas margens (no Brasil e no Paraguai) e que apresentam diferença no número e no perfil dos visitantes. Neste trabalho se propôs mensurar o CBBE do Complexo Turístico Itaipu no lado brasileiro e no lado paraguaio por meio de uma pesquisa quantitativa, tipo survey, com 671 visitantes, através de um questionário baseado em escalas multidimensionais utilizadas em medições de destinos turísticos. Os dados foram coletados em 2016 e 2017 e analisados através de estatística descritiva e análise estratificada. Foi observado alto valor de marca para todos os itens do CBBE, sobretudo na dimensão conhecimento, e evidenciaram-se diferenças entre a percepção de marca dos visitantes nacionais (brasileiros e paraguaios) em relação aos estrangeiros, bem como entre a percepção dos viajantes experientes em relação aos esporádicos, principalmente nas dimensões conhecimento e qualidade percebida.
Cidades dos mortos originando cidades para os vivos: Um estudo da representatividade do Cemitério do Alecrim, Natal (RN, Brasil) como opção de atrativo para o Turismo Mórbido
Authors: Silva Weslley Carlos
Published: September 2019

O Turismo Mórbido é decorrente do cenário da pós-modernidade, segmentação que vem se estabelecendo ao poucos em âmbito nacional, nas cidades europeias e em cidades da própria América do Sul, como é o caso de Buenos Aires em que já se promove este tipo de prática. O objetivo desta pesquisa foi fazer uma discussão acerca do uso da morbidade no Turismo, evidenciando casos em que o contexto mórbido estava ocorrendo de fato e que existe uma demanda turística emergindo em busca de espaços alternativos se contrapondo ao convencional do Turismo massivo. Ressalta-se, no decorrer deste trabalho, a importância de se prospectar o uso do espaço cemiterial como atrativo turístico e que é necessário romper as devidas rotulações que escondem um imensurável potencial que possui para o Turismo. Através da metodologia de análise bibliográfica se verificou com os autores mais relevantes da história do Rio Grande do Norte (ALVEAL, 2011; CARDOSO, 2000; CABRAL, 2006; CASCUDO, 1999) os apontamentos históricos sobre o Cemitério do Alecrim, situado na cidade de Natal (RN, Brasil). Consultas a documentos que contivessem informações históricas sobre o cemitério também foram realizadas. Como objeto de pesquisa deste trabalho vinculou-se esta modalidade do Turismo, sua apropriação como uma oferta turística potencial que deve ser utilizada. Verificou-se que a literatura sobre o Turismo mórbido é escassa dispondo-se de poucas pesquisas e abordagens neste campo do Turismo. Desta forma, o incremento de mais artigos científicos permitirá um melhor envolvimento do tema, propiciando maior clareza sobre suas vertentes.

Authors: Al Fannah Jehan , Al Rashdi Ismail , Al Harithy Harith , Al Salmi Qasem
Published: September 2019

Healthcare systems at an organizational level need to equip its people with tools that ensure continuous performance improvement to help sustain Universal Health Coverage (UHC). A large tertiary care public hospital in Oman (Royal Hospital [RH]), is sharing its experience in performance improvement using lean methodology. The RH introduced lean performance improvement to improve the efficiency of its administrative and clinical processes. This remarkable change was a cultural shift as it empowered clinical and non-clinical teams to improve the performance of the hospital operations continuously. Hospital leaders need to create opportunities for sustainable UHC at an organizational level. Introducing lean improvement methods at the hospital level leads to better problem definition and resolution. The people who do the work, need to improve the work, and eliminate waste in the processes as a day to day work style.
Lean thinking in total nursing care for mechanically ventilated patients: A new concept in ICU
Authors: Farghaly Sally Mohammed , Ahmed Fatma Refaat
Published: September 2019

Background: Lean approach is one of the coming revolutions for a better, improved, high-value-based care to maximize the benefit from nursing care activities. Additionally, it can shorten the mechanical ventilation duration and the total intensive care unit stay with a time and cost effective process. Lean is an improvement strategy based on the concept of eliminating the waste and creation of value-added care practices to the patients. Applying lean strategy for mechanically ventilated patients requires critical evaluation of all steps of the care to identify which add value and which do not.Methods: A descriptive research design was used in the current study and two tools were used for data collection in this study: “Lean assessment observational checklist of total care for mechanically ventilated patients”, and “Critical care nurses’ self-report about waste during total care of mechanically ventilated patients”.Results: The differences between value added and non-value added care practice items were not statistically significant in ventilator and patient care practices items (p = .232 and .884) respectively, while there was no statistical difference between the value added and non-value added care practice items in tube care. The differences between the time consumed in all care practices items were statistically significant (p < .001). According to the nurses' self-report, direct care for patients was ranked as the first care category that can increase the cost and effort followed by the indirect care category.Conclusions: Not all care items for mechanically ventilated patients have been added value to the patients. Waste outcomes as reported by nurses resulted in increase their efforts, time of care, in addition to increase the cost of care.

INTRODUCTION: Hand hygiene (HH), one of the most important preventive measures of Healthcare-associated infections (HCAIs), is often neglected by healthcare workers (HCWs) in low and middle-income countries (LMICs).

PURPOSE: The purpose of the study is to assess the role of a multimodal intervention (MMI) for enhancing hand hygiene compliance (HHC) of HCWs in a resource-limited setting.

METHODOLOGY: A pretest-posttest quasi-experimental study was conducted in five hospitals of Bangladesh where 984 HCWs (342 physicians and 642 nurses) were selected purposively. Using a structured checklist, a direct observational assessment was carried out on HCWs’ HHC both before and after the intervention. The MMI provided to HCWs comprised of: (i) system change, (ii) educational intervention, (iii) visual reminders, (iv) monitoring and performance feedback and (v) formation of infection control committees.

RESULTS: Following intervention, overall HH compliance before and after patient contact significantly increased (p<0.00) to 50.1% and 57.2% respectively across all hospitals, professional categories and activities. Nurses were more compliant to HH than physicians (OR = 1.1, 95% CI: 1.0-1.3, P < 0.01) after patient contacts. However, both groups showed equal HHC (OR = 1, CI: 0.9-1.1, P = 0.72) before patient contacts. HCWs of private hospitals were 1.5 times more compliant to HHC than that of public hospitals.

CONCLUSIONS: This study denotes that despite national policies on hand hygiene in Bangladesh, HCW’s compliance to HH is poor. Study findings also illustrate that a multimodal HH program resulted in significant improvement in HCWs’ HHC that deserves the potentials to assist the advancement of infection control practices targeting reduction of HCAIs.
U.S. Latino Leaders Versus the GLOBE’s Latin American and Anglo Cluster
Authors: Gil Karina
Published: September 2019

The current study compares the leadership preferences among Latino leaders in the U.S. and the GLOBE’s Latin American and Anglo Clusters. The study was done with a national sample size of 188 Latino leaders from all over the U.S. The surveying instrument used was sections 2 and 4 of the Alpha form of The Global Leadership and Organizational Behavior Effectiveness Questionnaire (GLOBE) by House et al. (2004) and a demographic survey developed by the researcher. t-Tests were used to compare the overall mean score of the research sample with the grand mean score of both the Latin American and Anglo clusters. Results indicate that Latino leaders in the U.S. had different leadership preference than the GLOBE’s Latin American and Anglo cluster. One of the main contributions of the research to the body of knowledge is that it brings to light the uniqueness of the Latino leadership preferences and shows how dissimilar their preference is from the Latin American and Anglo Clusters of the GLOBE.
Alleviation of ‘Generation Gap’ Through Socio-Economic Issues Involvement
Authors: Buheji Mohamed
Published: September 2019

The generation gap has been an issue that is rising in many communities. This paper investigates the challenges of ‘generation gap’ and propose a model for closing it. The synthesis of the literature review defines the types of generation gaps and the factors that increase this gap. The contemporary practices and measures used to close this intergeneration gap are identified. Two main approaches are retrieved as a reflection from the literature reviewed: mindset approach and socio-economic engagement approach.

The researcher presents a case study that proposes a theoretical framework about connecting the different generations and engaging them through solving socio-economic issues of common interest. The paper recommends further studies in this line where different generations would be engaged more to share knowledge and values and mitigate risks of further gap widening, while solving their socio-economic problems.
“FOLIA TURISTICA” IN 1990-2018 – A BIBLIOMETRIC ANALYSIS
Authors: Szczechowicz Bartosz
Published: September 2019

Purpose. The aim of this article is to investigate the characteristics of “Folia Turistica” (FT), covering such questions as thematic profile, authors, and affiliations, internationalization, taking into account the content of issues from the origins of the magazine (1990) to the present (2018).

Method. The aim of the work was achieved through two research methods, which were used in a complementary fashion: bibliometric analysis (in which data that quantitatively expressed the content of the relevant issues of FT was gathered, processed, and interpreted) and participatory observation, from the author’s participation in FT’s editorial staff.

Results. FT is predominantly concerned with issues in the social sciences, it is closely tied to the humanities, and the natural sciences are also present, though this profile has changed over time. Contributors to FT have included more than 400 Polish authors over thirty years, representing almost ninety schools, from academies of physical education and universities to economic, agriculture, natural science, and technical colleges, and others. Though the number of foreign authors is limited, we should stress that they represent academies on four continents, and in many cases are figures with very high positions in the international community.

Research and conclusions limitations. The limitations derive from the properties of the methods used, primarily displayed in the identification of FT’s thematic profile. This arbitrarily identified profile subordinates every article to a single overriding field of study – while many articles published in FT are multi- or interdisciplinary.

Practical implications. This diagnosis of FT includes postulates for how the magazine might develop in the future.

Originality. The specialist literature (especially Polish) fairly seldom makes critical evaluations of scholarly publications.

Type of article. Empirical.

The analyses found the numbers of citations of articles published in FT and the sum total of citations of published works in 1990-2016 in sources indexed in Google Scholar, Scopus, and Web of Science. This allowed us to establish the changing percentage of citations over the years and the average impact of articles published in various issues of the journal. Based on the data from the analyzed sources, an h-index was established for the journal, with the most frequently cited articles and their fields, as well as the most frequently cited authors of works of articles published in the relevant period. Data collected at Web of Science and Scopus allowed us to establish the number of references to articles published in „FT”, appearing in various years, titles, authors, sources, and fields, and the most often quoted publications published in „FT” and the countries with which these publications were affiliated. Research and conclusions limitations. The analysis concerns citations in Google Scholar and the Scopus and Web of Science (Core Collection) databases, accessed 8 March 2019 and limited to articles published in “Folia Turistica” in period 1990-2016. Practical implications. This analysis could be a source of information for defining the later publishing policies of “Folia Turistica” and a basis for future comparative analyses. Originality. This is the first analysis of citations of articles published in “Folia Turistica”. Type of work. This article presents the results of empirical studies.
CONTRIBUTION OF "FOLIA TURISTICA" JOURNAL TO THE DEVELOPMENT OF RESEARCH AND POPULARISATION OF ECONOMIC KNOWLEDGE IN THE SCOPE OF TOURISM
Authors: Gołembski Grzegorz
Published: September 2019

Purpose. The aim of the considerations is to evaluate the contribution of scientific articles published in the “Folia Turistica” journal in the years 1990-2018 to the development of research and popularisation of economic knowledge related to management at the micro, meso- and micro-economic level.

Method. For the implementation of the presented objective, scientific articles have been singled out - of all the works published in the given journal - the issues of which form part of the scope of economic sciences. Then, qualitative (expert) analysis of the content of these articles was performed in terms of the research problems undertaken in them, the methods applied for their solution and the results obtained in this manner. Attention was particularly paid to the methodological correctness of the analysed texts and their contribution to the development of economic reflection on the tourist activity of a human being - taking the state of economic knowledge appropriate for the times in which individual articles were created into account.

Findings. As a result of the above procedure, more than 40 scientific articles, strictly economic in nature, published in "Folia ..." were distinguished. These articles were grouped into 6 thematic blocks, which - in general - concerned: (1) the concept of "tourism economy", (2) macro-economic issues, (3) tourist demand and consumption, (4) tourist region, including sustainable development, (5) the competitiveness of hotel enterprises, and (6) knowledge transfer. Analysis of the content of articles included in each of these thematic blocks revealed that the works published on the pages of "Folia ..." create a broad, yet at the same time, coherent, even comprehensive collection of considerations in the field of tourism management. It is also worth noting that the authors publishing their works in the journal often undertook issues that, at the time of their publication, were innovative; a similar remark concerns the research methods used by them.

Research and conclusions limitations. The assessment of articles in the field of economic sciences published in "Folia ..." is qualitative (expert), thus the formulated conclusions are characterised by subjectivism.

Practical implications. The results of the analysis presented here and the conclusions drawn from them may prove to be useful for the editorial team of the “Folia Turistica” journal - indicating the right directions for undertaking initiatives related to the publishing of thematic issues with an economic profile.

Originality. The article contains an analysis of existing texts. However, due to the ordering nature and the critical view of the texts mentioned in it, it is an original study - relevant to the evaluation of one of the oldest tourist journals in Poland on the development of economic reflection on spatial mobility of people.
THE CONTRIBUTION OF ”FOLIA TURISTICA” IN THE DEVELOPMENT OF RESEARCH ON MARKETING IN TOURISM
Authors: Żemła Michał
Published: September 2019

Purpose. The aim of the work is to indicate the impact of publications from the "Folia Turistica" journal on the development of knowledge on marketing in tourism in Poland.

Method. The article analyses citability (as of 20 Oct. 2018) of articles published in the journal, addressing marketing issues. However, the article cannot be treated as a typical bibliometric study, because the most important conclusions were derived by deduction.

Findings. From among the very numerous articles published in the "Folia Turistica" issues, those devoted to the problem of marketing in tourism, or at least aspects related to it, are not very numerous. The contribution of this journal to the development of knowledge on marketing in tourism does not result from a large number of publications, but mainly from the publication of several items whose frequency of quoting makes them considered as very important publications (from those published in Poland) in the development of understanding the essence marketing in tourism.

Research and conclusions limitations. In the bibliometric research, the Google Scholar database was used, which although indexes the largest number of Polish scientific journals, is still very incomplete.

Practical implications. The text is an analysis of scientific publications and contains only a few guidelines for practitioners. Such a suggestion may be an indication of particularly scientifically influential texts on marketing in tourism, which may be of interest to economic practitioners.

Originality. So far, this type of analysis has not been conducted in Poland, not only in the case of "Folia Turistica", but also for other scientific journals related to research in the tourism industry.

Type of work. The article is of review nature.

Redução de Dados em Redes de Sensores sem Fio Baseada em Análise de Dispersão
Authors: de Oliveira Samuel Silva , Kniess Janine
Published: September 2019

Nas aplicações de monitoramento com Redes de Sensores sem Fio (RSSF), os sensores podem depender de fontes de energia limitada. Estudos apontam que a principal fonte de consumo de energia em nós sensores está relacionada à transmissão de dados. Neste artigo, apresenta-se uma abordagem para redução de dados baseada na análise da dispersão dos dados de sensores, visando evitar o envio de detecções cujos valores sejam pouco dispersos. Os experimentos realizados com dados de sensores reais e com o simulador Castalia mostraram que a abordagem proposta atingiu uma redução maior que 84%, mantendo um baixo nível de erros e baixo consumo de energia.
Uma Métrica de Roteamento com Eficiência Energética para o RPL da Internet das Coisas
Authors: Pereira Hermano , Moritz Guilherme Luiz , Fonseca Mauro
Published: September 2019

A Internet das Coisas está ganhando a atenção do mercado, da indústria e da comunidade científica. A integração das WSNs com a Internet levou a IETF a especificar novos protocolos. Um dos principais é o RPL, um protocolo de roteamento para redes que possuem perdas de pacotes consideráveis. Dentre as métricas de roteamento, destaca-se a ETX, que contribui na escolha de caminhos confiáveis. No entanto, a rápida exaustão de energia da bateria dos nós de gargalo ainda é um problema. Nesse contexto, apresenta-se aqui uma nova métrica baseada no consumo energético estimado da interface de rede, a qual colabora não apenas na confiabilidade, mas também no balanceamento de carga e no prolongamento do tempo de vida da rede.

Authors: Rettore Paulo H. L. , Araújo Ígor , Maia Guilherme , Villas Leandro A. , Loureiro Antonio A. F.
Published: September 2019

Este trabalho apresenta o T-Incident, uma arquitetura robusta de baixo custo para detecção e enriquecimento de eventos rodoviários baseado na fusão de dados heterogêneos. Foi desenvolvido um modelo espaço-temporal para fusão de dados de incidente, não-incidente e mídia social. Além disso, filtrou-se essa última fonte de dados usando métodos de processamento de linguagem natural para detecção de padrões capazes de descrever o evento e sua vizinhança. Também foi desenvolvido um modelo baseado em aprendizagem para identificar esses padrões e detectar os tipos de eventos. Os resultados da metodologia mostraram os melhores parâmetros para a abordagem T-Incident, fornecendo um serviço apurado de detecção e descrição de incidentes acima de 90% para as métricas F1 score, Recall e Precisão.
